SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS
This Quarterly Report on Form 10-Q may contain “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Securities Exchange Act of 1934, as amended. The Company’s forward-looking statements include, but are not limited to, statements regarding the Company’s or its management team’s expectations, hopes, beliefs, intentions or strategies regarding the future, including the Company’s expectations regarding the plans and strategy for our business, future financial performance, expense levels and liquidity sources. In addition, any statements that refer to projections, forecasts or other characterizations of future events or circumstances, including any underlying assumptions, are forward-looking statements. The words “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intends,” “may,” “might,” “plan,” “possible,” “potential,” “predict,” “project,” “should,” “would,” “goal” and similar expressions may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking.
The forward-looking statements contained in this Quarterly Report on Form 10-Q and in documents incorporated herein are based on the Company’s current expectations and beliefs concerning future developments and their potential effects on us taking into account information currently available to the Company. There can be no assurance that future developments affecting the Company will be those that the Company has anticipated. These forward-looking statements involve a number of risks, uncertainties (many of which are difficult to predict and beyond the Company’s control) or other assumptions that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements.
As a result of a number of known and unknown risks and uncertainties, the Company’s actual results or performance may be materially different from those expressed or implied by these forward-looking statements. Some factors that could cause actual results to differ include:
*the Company’s ability to raise financing in the future;
*the Company’s ability to service its operations and expenses and other liquidity needs and to address its ability to continue as a going concern;
*the ability to recognize the anticipated benefits of the Business Combination;
*the ability to maintain the listing of the NKGen common stock on the Nasdaq Global Market and its warrants on the Nasdaq Capital Market, and the potential liquidity and trading of such securities;
*the risk that the consummation of the Business Combination disrupts current plans and operations of the Company;
*costs related to the Business Combination and expenses and/or payments due to third parties;
*changes in applicable laws or regulations;
*the Company’s success in retaining or recruiting, or changes required in, our officers, key employees or directors after the Business Combination;
*the Company’s ability to successfully commercialize any product candidates that it successfully develops and that are approved by applicable regulatory authorities;
*the Company’s expectations for the timing and results of data from clinical trials and regulatory approval applications;
*the Company’s business, operations and financial performance including:
*the Company’s history of operating losses and expectations of significant expenses and continuing losses for the foreseeable future;
*the Company’s ability to execute its business strategy;
*the Company’s ability to develop and maintain its brand and reputation;
*the Company’s ability to partner with other companies;
*the size of the addressable markets for the Company’s product candidates;
*the Company’s expectations regarding its ability to obtain and maintain intellectual property protection and not infringe on the rights of others;
*the outcome of any legal proceedings that may be instituted against the Company; and
*unfavorable conditions in the Company’s industry, the global economy or global supply chain, including financial and credit market fluctuations, international trade relations, pandemics, political turmoil, natural catastrophes, warfare (such as the war between Russia and Ukraine and the armed conflict in Israel and the Gaza Strip and Israel’s declaration of war against Hamas), and terrorist attacks.
These forward-looking statements are based on information available as of the date of this Quarterly Report on Form 10-Q, and current expectations, forecasts and assumptions, and involve a number of risks and uncertainties. Accordingly, forward-looking statements in this Quarterly Report on Form 10-Q and in any document incorporated herein by reference should not be relied upon as representing the Company’s views as of any subsequent date, and the Company does not undertake any obligation to update forward-looking statements to reflect events or circumstances after the date they were made, whether as a result of new information, future events or otherwise, except as may be required under applicable securities laws.
You should read this Quarterly Report on Form 10-Q and the documents incorporated herein, completely and with the understanding that our actual future results may be materially different from what we expect. We qualify all of our forward-looking statements by these cautionary statements.
In addition, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based upon information available to us as of the date of this Quarterly Report on Form 10-Q and while we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and such statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain, and investors are cautioned not to unduly rely upon these statements.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
1.Company Information
NKGen Biotech, Inc. (“Company” or “NKGen”), a Delaware corporation headquartered in Santa Ana, California, is a clinical-stage biotechnology company focused on the development and commercialization of innovative autologous, allogeneic and CAR-NK natural killer cell therapies utilizing their proprietary SNK (Super-Natural-Killer) platform. The Company was formerly majority owned and controlled by NKMAX Co., Ltd. (“NKMAX”), a company formed under the laws of the Republic of Korea.
The Company was originally incorporated in Delaware on January 28, 2021 under the name Graf Acquisition Corp. IV (“Graf”), as a special-purpose acquisition company for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or engaging in any other similar business combination with one or more businesses or entities.
On April 14, 2023, the Company entered into the Agreement and Plan of Merger by and among Graf, Austria Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of Graf (“Merger Sub”), and NKGen Biotech, Inc. (“Merger Agreement”). Upon consummation of the transactions under the Merger Agreement on September 29, 2023 (the “Business Combination”), Merger Sub merged with and into NKGen Biotech, Inc. (“Legacy NKGen”) with Legacy NKGen surviving the merger as a wholly owned subsidiary of Graf (the “Merger”). In connection with the consummation of the Business Combination (the “Closing”), Graf was renamed to “NKGen Biotech, Inc.” and Legacy NKGen changed its name to “NKGen Operating Biotech, Inc.” The common stock and warrants of the combined company began trading on The Nasdaq Stock Market LLC under the symbols “NKGN” and “NKGNW”, respectively, on October 2, 2023.
Throughout the notes to the unaudited condensed consolidated financial statements, unless otherwise noted or otherwise suggested by context, the “Company” refers to Legacy NKGen prior to the consummation of the Business Combination, and the Company after the consummation of the Business Combination.
Liquidity
The Company follows Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 205-40, Presentation of Financial Statements — Going Concern, which requires that management evaluate whether there are relevant conditions and events that in aggregate raise substantial doubt about the entity’s ability to continue as a going concern and to meet its obligations as they become due within one year after the date that the unaudited condensed consolidated financial statements are issued. Under the guidance, the Company must first evaluate whether there are conditions and events that raise substantial doubt about the entity’s ability to continue as a going concern (step 1). If the Company concludes substantial doubt is raised, management also is required to consider whether its plans alleviate that doubt (step 2).
The Company has a limited operating history, has incurred significant operating losses since its inception, and the revenue and income potential of the Company’s business and market are unproven. The Company’s unaudited condensed consolidated financial statements are prepared using the generally accepted accounting principles applicable to a going concern, which contemplates the realization of assets and liquidation of liabilities in the normal course of business. As of March 31, 2024, the Company had an accumulated deficit of $167.5 million and cash and cash equivalents of less than $0.1 million. To date, the Company has funded its operations primarily with the net proceeds from the issuance of senior convertible promissory notes, the issuance of related party loans, the issuance of bridge loans, the issuance of convertible bridge loans, the issuance of convertible 12% promissory notes, draws upon a revolving line of credit, the issuance and sale of equity securities, PIPE warrants, private placements, the amendment of private placements, and proceeds from the Business Combination. The Company expects to incur substantial operating losses for the next several years and will need to obtain additional near-term financing in order to continue its research and development activities, initiate and complete clinical trials and launch and commercialize any product candidates for which it receives regulatory approval. Management has prepared cash flow forecasts which indicate that based on the Company’s expected operating losses and negative cash flows, there is substantial doubt about the Company’s ability to continue as a going concern for twelve months from the issuance of these unaudited condensed consolidated financial statements.
The Company plans to continue to fund its losses from operations and capital funding needs through additional debt or equity financings to be received from related parties, private equity, or other sources. If the Company is not able to secure adequate additional funding, the Company may be forced to make reductions in spending, extend payment terms with suppliers, liquidate assets where possible, suspend or curtail planned programs, or may be forced to cease operations or file for bankruptcy protection. Any of these actions could materially harm the Company’s business, results of operations and future prospects. There can be no assurance that such financing will be available or will be at terms acceptable to the Company. The preparation of these unaudited condensed consolidated financial statements does not include any adjustments that may result from the outcome of this uncertainty.
2.Summary of Significant Accounting Policies
Basis of Presentation
NKMAX held a majority of the voting power of Legacy NKGen before the Business Combination and continued to hold a majority of the voting power of the Company after the Business Combination. Therefore, as there was no change in control, the Business Combination was accounted for as a common control transaction with respect to Legacy NKGen along with a reverse recapitalization of the Company. Accordingly, for accounting purposes, the financial statements of the Company represent a continuation of the financial statements of Legacy NKGen with the Business Combination being treated as the equivalent of Legacy NKGen issuing shares for the net assets of Graf, accompanied by a recapitalization. The net assets of Graf were recognized as of the Closing at historical cost, with no goodwill or other intangible assets recorded. Operations prior to the Business Combination are presented as those of Legacy NKGen and the accumulated deficit of Legacy NKGen has been carried forward after Closing.
Upon the consummation of the Business Combination, all of Legacy NKGen’s equity was converted into equity of the Company based upon an exchange ratio (“Exchange Ratio”). In addition, all stock options of Legacy NKGen were converted using the Exchange Ratio into options exercisable for shares of the Company with the same terms and vesting conditions. The Exchange Ratio as of September 29, 2023, the date of Closing, was approximately 0.408.
All periods prior to the Business Combination have been retrospectively adjusted using the Exchange Ratio to reflect the reverse recapitalization. In connection with the reverse recapitalization treatment of the Business Combination, all issued and outstanding securities of Graf upon Closing were treated as issuances of the Company upon the consummation of the Business Combination.
The accompanying financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) and generally accepted accounting principles in the United States of America (“US GAAP”). The Company maintains its accounting records under the accrual method of accounting in conformity with US GAAP. The condensed consolidated balance sheet as of December 31, 2023 included herein was derived from the audited financial statements as of that date. Certain information and disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such regulations. Accordingly, these unaudited condensed consolidated financial statements and accompanying footnotes should be read in conjunction with NKGen’s financial statements as of and for the year ended December 31, 2023. The results for the interim periods are not necessarily indicative of results for the full year.
In the opinion of management, all adjustments, of a normal recurring nature, considered necessary for a fair presentation have been included in the unaudited condensed consolidated financial statements. The Company believes that the disclosures provided herein are adequate to prevent the information presented from being misleading.
Principles of Consolidation
The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiary. All significant intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates
The preparation of unaudited condensed consolidated financial statements in accordance with US GAAP requires management to make estimates and assumptions that impact the reported amounts of certain assets and liabilities, certain disclosures at the date of the unaudited condensed consolidated financial statements, as well as the reported amounts of revenues and expenses during the reporting period. The most significant estimates in the Company’s unaudited condensed consolidated financial statements include, but are not limited to, accrued clinical and research and development expenses, legacy convertible notes, convertible 12% promissory notes, senior convertible promissory notes due to related parties, forward purchase derivative liabilities, derivative warrant liabilities, derivative warrant assets, common stock, and equity awards. These estimates and assumptions are based upon historical experience, knowledge of current events, and various other factors believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the recording of expenses that are not readily apparent from other sources. Actual results could differ materially from those estimates.
Restricted Cash
Restricted cash consists of funds that are contractually restricted due to a revolving line of credit, which was entered into during June 2023. In accordance with the terms of the revolving line of credit, the Company was required to maintain $15.0 million in cash balances with the lender from March 31, 2024 until repayment of all principals and other payables to the lender under the revolving line of credit was made as additional collateral for the borrowings. In April 2024, the lender subsequently waived the minimum cash deposit requirement in exchange for the Company's agreement to use the lender as their primary banking relationship. As of both March 31, 2024 and December 31, 2023, $0.3 million in restricted cash was recorded on the unaudited condensed consolidated balance sheet. The Company includes its restricted bank deposits in cash, cash equivalents and restricted cash when reconciling beginning-of-period and end-of-period total amounts shown on the unaudited condensed consolidated statements of cash flows for the three months ended March 31, 2024.
Deferred Debt Issuance Costs
Costs incurred through the issuance of the revolving line of credit to parties who are providing short-term financing availability are reflected as deferred debt issuance costs. These costs are generally amortized to interest expense over the life of the financing instrument using the effective interest rate method or other methods approximating the effective interest method. As of both March 31, 2024 and December 31, 2023, less than $0.1 million in deferred debt issuance costs were recorded to prepaid expenses and other current assets on the unaudited condensed consolidated balance sheets.
Hybrid Instruments
The Company follows Financial Accounting Standards Board (“FASB”) Accounting Standard Codification (“ASC”) 480, Distinguishing Liabilities from Equity, when evaluating the accounting for its hybrid instruments. A financial instrument that embodies an unconditional obligation, or a financial instrument other than an outstanding share that embodies a conditional obligation, that the issuer must or may settle by issuing a variable number of its equity shares shall be classified as a liability (or an asset in some circumstances) if, at inception, the monetary value of the obligation is based solely or predominantly on any one of the following: (a) a fixed monetary amount known at inception; (b) variations in something other than the fair value of the issuer’s equity shares; or (c) variations inversely related to changes in the fair value of the issuer’s equity shares. Hybrid instruments meeting these criteria are not further evaluated for any embedded derivatives and are carried as a liability at fair value at each balance sheet date.
Derivative Instruments
FASB ASC 815, Derivatives and Hedging Activities, requires companies to bifurcate certain features from their host instruments and account for them as free-standing derivative financial instruments should certain criteria be met. The Company does not use derivative instruments to hedge exposures to interest rate, market, or foreign currency risks. The Company evaluates its financial instruments to determine whether such instruments are derivatives or contain features that qualify as embedded derivatives. Embedded derivatives must be separately measured from the host contract if all the requirements for bifurcation are met. The assessment of the conditions surrounding the bifurcation of embedded derivatives depends on the nature of the host contract and the features of the derivatives. Bifurcated embedded derivatives are recognized at fair value, with changes in fair value recognized in the unaudited condensed consolidated statements of operations and comprehensive loss each period. Bifurcated embedded derivatives are classified with the related host contract in the Company’s unaudited condensed consolidated balance sheets. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is re-assessed at the end of each reporting period.
Debt
For convertible debt instruments that are not considered liabilities under ASC 480 or ASC 815, the Company applies ASC 470, Debt, for the accounting of such instruments, including any premiums or discounts. The Company’s bridge loans, senior convertible promissory notes, and convertible bridge loans accounted for under ASC 470. Accrued interest paid-in-kind is added to the carrying amount of the Company’s senior convertible promissory notes.
Subscription and Shareholder Receivables
The Company records stock issuances at the effective date. If the amounts are not funded upon issuance, the Company records a subscription receivable or shareholder receivable as an asset on the balance sheet. When subscription receivables or shareholder receivables are not received prior to the balance sheet date in satisfaction of the requirements under ASC 505, Equity, the subscription or shareholder receivable is reclassified as a contra account to stockholder’s equity (deficit) on the balance sheet.
Shareholder receivables represent amounts due from shareholders. If the shareholder does not fund the receivable prior to the balance sheet date, the Company records a receivable that is reclassified as a contra account to stockholder’s deficit on the balance sheet. During March 31, 2024, $0.5 million due from shareholders was received by the Company.
Impairment of Long-Lived Assets
The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate the carrying amount of an asset, or asset group, may not be recoverable. Recoverability is measured by a comparison of the carrying amount of an asset or asset group to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset or asset group exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset or asset group exceeds the fair value of the asset or asset group. The Company has not recognized any impairment losses for the three months ended March 31, 2024 and 2023.
Fair Value Option
In lieu of bifurcation, on an instrument-by-instrument basis, the Company may elect the fair value option for certain financial instruments that meet the required criteria under ASC 825, Financial Instruments. The Company elected the fair value option for both its legacy convertible notes and convertible 12% promissory notes, which met the required criteria under ASC 825, Financial Instruments. Interest expense associated with both the legacy convertible and convertible 12% promissory notes is included in the change in fair value of such instruments.
Fair Value of Financial Instruments
The Company accounts for the fair value of its financial instruments under the framework established by US GAAP which defines fair value and expands disclosures about fair value measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The standard describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value. These estimates may be subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision.
Level 1 — Quoted prices in active markets for identical assets or liabilities the Company has the ability to access at the measurement date.
Level 2 — Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of assets or liabilities.
Level 3 — Pricing inputs that are unobservable, supported by little or no market activity and are significant to the fair value of the assets or liabilities.
Transfers to/from Levels 1, 2, and 3 are recognized at the beginning of the reporting period. There were no transfers to/from Levels 1, 2, and 3 during three months ended March 31, 2024 and 2023.
ASC 820, Fair Value Measurement, states that in many cases, the transaction price will equal the fair value (for example, that might be the case when on the transaction date, the transaction to buy an asset takes place in the market in which the asset is sold). In determining whether a transaction price represents the fair value at initial recognition, the Company considers various factors such as whether the transaction was between related parties, is a forced transaction, or whether the unit of account for the transaction price does not represent the unit of account for the measured instrument.
The Company does not measure assets at fair value on a recurring basis. The Company's liabilities that are measured at fair value on a recurring basis are its liability classified warrants, convertible 12% promissory notes, and forward purchase derivative liabilities. Refer to Note 9, Fair Value of Financial Instruments, for further discussion regarding the Company’s fair value measurements. The carrying value of the Company’s related party loans approximates fair value as the stated interest rate approximates market rates for similar loans and due to the short-term nature of such loans, which are due within three years or less from issuance. The carrying value of the Company’s cash, restricted cash, accounts payable, accrued expenses, bridge loans, convertible bridge loans, other current liabilities, and revolving line of credit approximates fair value primarily due to the short-term nature of such accounts.
Leases
The Company accounts for its leases under ASC 842, Leases. The operating lease right-of-use (“ROU”) asset represents the Company’s right to use an underlying asset during the lease term, and operating lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating leases are included in the ROU asset, current operating lease liabilities, and non-current operating lease liabilities in the accompanying condensed consolidated balance sheets. The operating lease ROU asset and lease liabilities are initially recognized based on the present value of the future minimum lease payments over the lease term at commencement date calculated using the Company’s incremental borrowing rate applicable to the lease asset, unless the implicit rate is readily determinable. The operating lease ROU asset also includes any lease payments made at or before lease commencement and exclude any lease incentives received. The Company determines the lease term as the noncancelable period of the lease and may include options to extend or terminate the lease when it is reasonably certain the Company will exercise that option. Leases with a term of 12 months or less are not recognized in the balance sheet. The Company’s leases do not contain any residual value guarantees. Lease expense for minimum lease payments is recognized as rent expense on a straight-line basis over the lease term. Operating expenses such as common area maintenance and utilities are treated as variable lease payments.
Stock-Based Compensation
Stock-based compensation expense is comprised of stock options awarded to employees and consultants. The Company accounts for share-based awards under the fair value method prescribed by ASC 718-10, Stock Compensation. The fair value of stock options is estimated using the Black-Scholes option pricing model on the date of grant. This option pricing model involves a number of estimates, including the per share value of the underlying common stock, exercise price, estimate of future volatility, expected term of the stock option award, risk-free interest rate and expected annual dividend yield.
The fair value of the shares of common stock underlying the stock options has historically been determined by the Company’s board of directors as there was no public market for the underlying common stock prior to October 2, 2023. The Company’s board of directors determines the fair value of the Company’s common stock by considering a number of objective and subjective factors including contemporaneous third-party valuations of its common stock, the valuation of comparable companies, sales of the Company’s common stock to outside investors in arms-length transactions, the Company’s operating and financial performance, the lack of marketability, and general and industry specific economic outlook, and the implied fair values upon a merger transaction, amongst other factors.
The Company recognizes the expense for options with graded-vesting schedules on a straight-line basis over the requisite service period, which is generally the vesting period. Forfeitures are recognized as they occur.
Basic and Diluted Net Loss Per Common Share
Basic net loss per common share is computed by dividing net loss for the year by the weighted-average number of common shares outstanding during the year. Diluted net loss per share is computed by dividing the net loss by the weighted-average number of common shares outstanding and potentially dilutive securities outstanding for the period using the treasury stock or if-converted method if their inclusion is dilutive. Diluted net loss per common share is the same as basic net loss per common share because the inclusion of potentially dilutive shares would be anti-dilutive to the calculation of net loss per common share.
The Company has one class of shares issued and outstanding. Accordingly, basic and diluted net loss per share is not allocated among multiple classes of shares. Basic and diluted net loss per share for all periods prior to the Closing have been retrospectively adjusted by the Exchange Ratio to affect the reverse recapitalization.
Potentially anti-dilutive shares excluded from the calculation of diluted net loss per share for three months ended March 31, 2024 include the following:
| | | | | |
Private warrants | 4,721,533 |
Working capital warrants | 523,140 |
Public warrants | 3,432,286 |
PIPE warrants | 10,209,994 |
Stock options | 1,969,261 |
SPA warrants | 1,000,000 |
Senior convertible notes’ shares | 1,000,000 |
Deferred founder shares (1) | 1,173,631 |
Convertible bridge loan warrants | 1,250,000 |
Convertible bridge loan consideration shares | 7,334 |
Convertible bridge loans | 619,146 |
Convertible 12% promissory note warrants | 660,000 |
Convertible 12% promissory notes | 367,850 |
Total | 26,934,175 |
(1)As described in Note 8, Related Party Transactions, deferred founder shares do not have voting rights, do not participate in dividends and are not transferrable absent the Company’s consent. Therefore, while deferred founder shares are considered outstanding for legal purposes and are included in the total quantity of outstanding shares on the unaudited condensed consolidated statements of stockholders’ deficit, they are not considered outstanding for accounting purposes, including basic and diluted net loss per share purposes.
Emerging Growth Company
The Company is an “Emerging Growth Company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart our Business Startups Act of 2012, (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved.
Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s unaudited condensed consolidated financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.
Recently Issued Accounting Pronouncements Not Yet Adopted
In December 2023, the FASB issued ASU No. 2023-09, Improvements to Income Tax Disclosures (Topic 740). The ASU requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as additional information on income taxes paid. The ASU is effective on a prospective basis for annual periods beginning after December 15, 2024. Early adoption is also permitted for annual financial statements that have not yet been issued or made available for issuance. This ASU will result in the required additional disclosures being included in the Company's unaudited condensed consolidated financial statements, once adopted. The Company is currently evaluating the impact of this standard on its financial statements and related disclosures.
3.Reverse Recapitalization
As discussed in Note 1, Company Information, the Closing of the Business Combination occurred on September 29, 2023. In connection with the Business Combination:
•All of Legacy NKGen’s legacy convertible notes were converted into shares of Legacy NKGen common stock immediately prior to Closing and pursuant to their terms, totaling 5,579,266 shares, which were then cancelled and converted into 2,278,598 shares of the Company’s common stock after giving effect to the Exchange Ratio;
•All of Legacy NKGen’s 38,185,814 issued and outstanding shares were cancelled and converted into 15,595,262 shares of the Company’s common stock after giving effect to the Exchange Ratio (inclusive of shares attributable to the Legacy NKGen convertible notes);
•All of Legacy NKGen’s 5,146,354 issued and outstanding stock options were cancelled and converted into 2,101,760 outstanding stock options of the Company;
•The Company’s amended and restated certificate of incorporation and amended and restated bylaws were adopted;
•The Company adopted an employee stock purchase plan; and

(1)The Graf transaction costs includes a $4.0 million accrual related to a certain vendor to be paid in cash and common stock of $2.0 million each. At Closing, a cash payment of $1.3 million was disbursed to this vendor. The remaining $2.7 million amount was recognized as a component of the unpaid transaction costs assumed from Graf, of which $0.7 million represents a cash settlement obligation, and the remaining $2.0 million represents an obligation to issue a variable number of shares for a fixed monetary amount which was accounted for as a liability under ASC 480, Distinguishing Liabilities from Equity (“ASC 480”). Under ASC 480, the obligation to issue shares is not subsequently measured at fair value with changes recorded in earnings because the monetary amount is fixed.
(2)Represents allocated fair value.
4.Private Placement
Initial Recognition
Background
Prior to the Closing, the Company entered into private agreements (“Private Placement Agreements”) with investors (“FPA Investors”) consisting of forward purchase agreements (“Forward Purchase Agreements”), subscription agreements, a side letter, and escrow agreements. The Private Placement Agreements closed on September 29, 2023. Pursuant to the Private Placement Agreements, the FPA Investors purchased 3,168,121 shares of common stock (“FPA Shares”) for $32.9 million (“Prepayment Amount”).
The Prepayment Amount was deposited into escrow accounts. The terms of the Private Placement Agreements provide that following a one-year period after the Closing, subject to early termination and settlement with respect to any number of FPA Shares at the election of the FPA Investors (“Measurement Period”), funds in the escrow accounts may be released to the FPA Investors, the Company or a combination of both based on a combination of factors, including the volume weighted average price of the Company’s common stock (“VWAP”) over a specified valuation period during the Measurement Period (“Reset Price”), the number of shares sold by the FPA Investors during the Measurement Period, and the application of anti-dilution provisions. The Private Placement Agreements expire at the end of the Measurement Period.
All funds in escrow will be released to the Company, the FPA Investors, or a combination of both, at or before the one year anniversary of the Closing. The maximum and minimum that could be released from escrow is the Prepayment Amount and zero, respectively, for both the FPA Investors and the Company. In addition, all interest earned on the funds in the escrow accounts will be released to the FPA Investors.
During the Measurement Period, to the extent the Company’s share price approaches or exceeds $10.44 per share, the likelihood and amount of escrow funds to be released to the Company increases and the likelihood and amount of escrow funds to be released to the FPA Investors decreases. Conversely, during the Measurement Period, to the extent the Company’s share price decreases below $10.44 per share, the likelihood and amount of escrow funds to be released to the Company decreases and the likelihood and amount of escrow funds to be released to the FPA Investors increases. Other drivers of settlement outcomes include the number of shares sold by FPA Investors to third parties during the Measurement Period, whereby the selling of shares may decrease portions of escrow funds to be released to the FPA Investors by up to $2.00 per share sold, the application of antidilution provisions, the timing of sales and settlements, among other factors. Additionally, a prepayment shortfall of $0.1 million was established in connection with the Private Placement Agreements (“Prepayment Shortfall”). Pursuant to the terms and conditions of the Private Placement Agreements, sales of FPA Shares to third-parties are required to first be applied towards the Prepayment Shortfall prior to the subscription receivable (described further below).
In addition to the FPA Shares, the FPA Investors received 514,889 shares of common stock for no incremental consideration (“Bonus Shares”). The Bonus Shares are not subject to an escrow arrangement.
Accounting
All FPA Shares and Bonus Shares are outstanding shares of the Company that are not held in escrow, are transferable without restrictions, and have the same voting as well as dividend and liquidation participation rights as other shares of the Company. Accordingly, such shares are equity classified and presented together with other shares of common stock in the unaudited condensed consolidated financial statements.
The escrow agreements provide that funds placed into escrow are held in escrow for the benefit of the FPA Investors until they are released to the Company pursuant to the terms of the Private Placement Agreements and the Company’s creditors do not have access to the funds held in escrow in the event of bankruptcy of the Company. Accordingly, the Company accounted for the original Prepayment Amount of $32.9 million as a contra-equity subscription receivable because the funds held in escrow represent receivables from shareholders.
The features of the Private Placement Agreements met the derivatives criteria under ASC 815 because they contained an underlying, notional amount, payment provision, and net settlement. Accordingly, a derivative liability was recognized based on the estimated measurement of the portion of the funds in escrow that could be released to the FPA Investors, based on circumstances existing as of Closing. The net balance of the Prepayment Amount presented as a subscription receivable and the derivative liability when considered together represents the estimated amount of escrow funds the Company expects to receive from the escrow accounts. Subsequent changes in fair value of the derivative liability associated with the Private Placement Agreements will be recognized through earnings on a quarterly basis.
Upon the Closing, in addition to the $32.9 million subscription receivable, a loss on issuance of forward purchase contract totaling $24.5 million was recorded, which consisted of fair value of the derivative liabilities of $20.2 million plus the fair value of the Bonus Shares of $4.3 million. The forward purchase derivative liabilities are treated as a current liabilities because the Private Placement Agreements mature or otherwise are subject to early termination at or prior to the one year at or before the one year anniversary of the Closing.
December 2023 Amendment
On December 26, 2023, the Company and an FPA Investor entered into an amendment to their Forward Purchase Agreement ("December 2023 FPA Amendment") for total proceeds of $0.5 million. No other Private Placement agreements were amended during the year ended December 31, 2023. The FPA Amendment provided that, (i) 200,000 FPA Shares were re-designated to Bonus Shares, (ii) the definition of Reset Price was changed (“Amended Reset Price”), (iii) the definition of the prepayment shortfall was amended (“Amended Prepayment Shortfall”), and (iv) the funds in the escrow account were transferred to a separate account held by the FPA Investor. The funds from the FPA Investor in connection with the amendment were not received by the Company until January 2024.
The terms of the Amended Reset Price provide for (i) a rolling ceiling effective as of the FPA Amendment execution date based on a weekly trailing VWAP such that the Company does not benefit from increases in share price during the Measurement Period, and (ii) discounts of generally 10.0% to the VWAP measurement that benefit the FPA Investor.
Proceeds from the sale of FPA Shares by FPA Investors to third parties are required to be treated as a reduction to the prepayment shortfall until no balance remains in the prepayment shortfall (“Shortfall Sales”), at which point proceeds from such sales of stock may be treated as reductions to the subscription receivable that may result in cash proceeds to the Company. If all FPA Shares are sold without full satisfaction of the prepayment shortfall, the Company is required, at their election, to either pay a cash amount equal to the remaining prepayment shortfall balance or issue additional shares at 90.0% of the VWAP for the trailing 20 trading days.
The terms of the Amended Prepayment Shortfall provide for a $0.5 million increase to the FPA Investor’s pre-existing prepayment shortfall of $0.1 million.
Upon execution of the FPA Amendment in December 2023, the Company recognized a loss on amendment to forward purchase contract as set forth below (in thousands):
| | | | | |
| Loss on Amendment |
Reduction of subscription receivable | $ | 15,123 |
Change in fair value in connection with the amendment of forward purchase contracts | (14,181) |
Cash received in connection with the amendments | (500) |
Loss on amendment to forward purchase contracts | $ | 442 |
The $0.4 million loss recognized in connection with the FPA Amendment represents the reduction in cash proceeds the Company may receive under the forward purchase contract, partially offset by the reduction in the forward purchase derivative liabilities and the shareholder receivable. As a result of the FPA Amendment, the maximum cash proceeds the Company could receive under the forward purchase contract, reflected in the subscription receivable balance, was lowered. The reduction in the subscription receivable of $15.1 million was caused by (i) the Amended Reset Price, which reduced the maximum price per FPA Share the Company could receive (initially, $10.44 per share), (ii) the re-designation of 200,000 FPA Shares to Bonus Shares, reducing the total quantity of FPA Shares, and (iii) the Amended Prepayment Shortfall, which increased the prepayment shortfall amount. The Company does not receive any consideration for sales or settlements of Bonus Shares or Shortfall Sales, described further below. In addition to the reduction in the subscription receivable, the Company recognized a corresponding reduction in the fair value of the forward purchase derivative liabilities of $14.2 million.
January and February 2024 Amendments
From January to February 2024, the Company and certain FPA Investors entered into several additional amendments to the Forward Purchase Agreements ("2024 FPA Amendments") for total proceeds to the Company of $1.0 million. The 2024 FPA Amendments provided that, (i) 200,000 additional FPA Shares were re-designated to Bonus Shares, (ii) the definition of the prepayment shortfall consideration was further amended (“2024 Amended Prepayment Shortfall”), and (iii) for the FPA Investor who was not party to the December 2023 FPA Amendment, the definition of Reset Price was changed (“2024 Amended Reset Price”).
The terms of the 2024 Amended Reset Price provide the FPA Investor (i) a rolling price per share effective as of the FPA Amendment execution date based on a weekly trailing VWAP, subject to a ceiling of $10.44 per share ("Initial Price"), and (ii) discounts of generally 10.0% to the VWAP measurement that benefit the FPA Investor.
The terms of the 2024 Amended Prepayment Shortfall provide for an aggregate $1.1 million increase to the FPA Investors’ pre-existing prepayment shortfall of $0.7 million.
Upon execution of the 2024 FPA Amendments, the Company recognized a loss on amendment to forward purchase contract as set forth below (in thousands):
| | | | | |
| Loss on Amendment |
Reduction of subscription receivable | $ | 2,764 |
Reduction in forward purchase derivative liabilities | (1,418) |
Cash received in connection with the amendments | (950) |
Loss on amendment to forward purchase contracts | $ | 396 |
The $0.4 million loss recognized in connection with the 2024 FPA Amendments represents the reduction in cash proceeds the Company may receive under the forward purchase contract, partially offset by the reduction in the forward purchase derivative liability and the shareholder receivable. As a result of the 2024 FPA Amendments, the maximum cash proceeds the Company could receive under the forward purchase contract, reflected in the subscription receivable balance, was lowered. The reduction in the subscription receivable of $2.8 million was caused by (i) the existing 2024 Amended Reset Price provisions as of the effective date of the 2024 FPA Amendments, (ii) the re-designation of 200,000 additional FPA Shares to Bonus Shares, further reducing the total quantity of FPA Shares outstanding, and (iii) the 2024 Amended Prepayment Shortfall, which increased the prepayment shortfall amount by an incremental $1.1 million. In addition to the reduction in the subscription receivable, the Company recognized a corresponding reduction in the fair value of the forward purchase derivative liabilities of $1.4 million.
Sales of FPA Shares and Settlements of Forward Purchase Contracts
Pursuant to the terms and conditions of the Private Placement Agreements, any sales of the Company’s common stock associated with the Private Placement Agreements may not be treated as sales of Bonus Shares until all FPA Shares are sold, at which point such sales of stock may be considered sales of Bonus Shares.
As set forth above in this note, the forward purchase derivative liabilities represent the portion of the subscription receivable that may be released to the FPA Investors rather than the Company. Immediately prior to the settlement of a forward purchase contract, the derivative liability balance is adjusted to the applicable subscription receivable balance less the cash proceeds to be received as of the settlement date, recognized within the change in fair value of forward purchase derivative liabilities. Upon settlement of a forward purchase contract, the respective derivative liability and subscription receivable balances are derecognized and the cash proceeds to be received are recognized by the Company. Refer to Note 9, Fair Value of Financial Instruments, for further discussion.
As of March 31, 2024, certain FPA Investors sold an aggregate of 1,768,121 shares of the Company’s common stock to third parties, representing all of the outstanding FPA Shares under the respective agreements. No other sales of FPA Shares occurred during the three months ended March 31, 2024.

In connection with Graf’s initial public offering (“IPO”), 3,432,286 warrants were issued to Graf’s investors (“Public Warrants”). The Public Warrants, which entitle the registered holder to purchase one share of the Company’s common stock, have an exercise price of $11.50 per warrant, became exercisable 30 days after the completion of the Business Combination, and are set to expire five years from the completion of the Business Combination, or earlier upon redemption. The Public Warrants may be called for redemption at the sole discretion of the Company if the Company’s stock price equals or exceeds $18.00 per share and other certain conditions are met. The Public Warrants are equity classified due to terms indexed to the Company’s own stock and the satisfaction of other equity classification criteria.
Private Warrants
Concurrently with Graf’s IPO, Graf issued 4,721,533 warrants to Graf Acquisition Partners IV LLC (“Private Warrants”). The terms of the Private Warrants are identical to the Public Warrants with an exercise price of $11.50 per warrant, except that they are subject to certain transfer and sale restrictions and are not optionally redeemable so long as they are held by the initial purchasers or their permitted transferees. Additionally, the Private Warrants are exercisable on a cashless basis. If the Private Warrants are held by a party other than the initial purchasers or their permitted transferees, the Private Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants. The Private Warrants are liability classified due to terms not indexed to the Company’s own stock. As described in Note 8, Related Party Transactions, the Private Warrants are a related party financial instrument. Private Warrants are classified to non-current liabilities because their term ends beyond one year from the latest unaudited condensed consolidated balance sheet date.
SPA Warrants
Together with the issuance of the Senior Convertible Notes described in Note 6, Convertible Notes, 1,000,000 warrants were issued to NKMAX at an exercise price of $11.50 per warrant (“SPA Warrants”). The terms of the SPA Warrants are identical to the terms of the Public Warrants with redemption at the sole discretion of the Company if the Company’s stock price equals or exceeds $18.00 per share and other certain conditions are met. The SPA Warrants are equity classified due to terms indexed to the Company’s own stock and the satisfaction of other equity classification criteria, including redemption in the Company’s control if the Company’s stock price equals or exceeds $18.00 per share. As described in Note 8, Related Party Transactions, the SPA Warrants are a related party financial instrument.
Working Capital Warrants
Prior to the Closing, Graf executed drawdowns upon a working capital loan facility. Upon Closing, the $0.8 million balance of the working capital loan facility was settled through the issuance of 523,140 warrants (“Working Capital Warrants”). The terms of the Working Capital Warrants are identical to the terms of the Private Warrants with an exercise price of $11.50 per warrant. The Working Capital Warrants are liability classified due to terms not indexed to the Company’s own stock. As described in Note 8, Related Party Transactions, the Working Capital Warrants are a related party financial instrument. Working Capital Warrants are classified to non-current liabilities because their term ends beyond one year from the latest unaudited condensed consolidated balance sheet date.
PIPE Warrants
Prior to the Closing, the Company entered into warrant subscription agreements (the “Warrant Subscription Agreements”) with certain investors (“Warrant Investors”), which closed on September 29, 2023. Pursuant to the Warrant Subscription Agreements, the Warrant Investors purchased an aggregate of 10,209,994 warrants, at a purchase price of $1.00 per warrant (“PIPE Warrants”) for total proceeds of $10.2 million. The PIPE Warrants are exercisable for cash (or by “cashless” exercise under certain circumstances) during the five-year period beginning on the Closing. One-third of the PIPE Warrants are exercisable initially at $10.00 per warrant, one-third of the PIPE Warrants are exercisable initially at $12.50 per warrant, and one-third of the PIPE Warrants are exercisable initially at $15.00 per warrant. The initial exercise prices of each tranche are subject to adjustment every 180 days after the Closing based upon declines in trading prices of the Company’s common stock, as well as antidilutive adjustments for stock splits, stock dividends, and the like. In addition, the PIPE Warrants contain a downside protection provision, pursuant to which the Warrant Investors may demand a cashless exchange of certain PIPE Warrants and, to the extent the relevant reference price is less than $1.50 per share, a cash payment calculated as the difference between $1.50 per share and the then-current exercise price multiplied by the applicable number of warrant shares shall be paid to the Warrant Investors. The PIPE Warrants are liability classified due to terms not indexed to the Company’s own stock and their cash settlement provisions. PIPE Warrants are classified to non-current liabilities because their term ends beyond one year from the latest unaudited condensed consolidated balance sheet date.
PIPE Warrant Amendment
On February 9, 2024, the Company amended their Warrant Subscription Agreement with a Warrant Investor ("PIPE Warrant Amendment") to, among other things, grant the Warrant Investor, (i) the right to exchange each PIPE Warrant for a newly registered share, effectively waiving the original strike price, (ii) a “Most Favored Nation” status with respect to warrant restructuring such that they may amend the terms upon the Company executing a similar transaction with more favorable terms for so long as any subscription warrants remain outstanding, and (iii) certain registration rights. In exchange, the Company received an upfront cash payment of $0.3 million and the right to receive a second cash payment of up to $0.3 million based on the trailing 5-day VWAP following the effective registration of the shares ("Deferred Payment"). The Deferred Payment is reflected within the fair value of the PIPE Warrant derivative liabilities under ASC 815, Derivatives and Hedging. All other terms and conditions remained unchanged.
| | | | | |
| PIPE Warrant Amendment |
Cash proceeds | $ | 250 |
Reduction in PIPE Warrant derivative liability | 429 |
Gain on amendment of PIPE warrant agreement | $ | 679 |
The reduction in the PIPE Warrant derivative liability was primarily attributable to the removal of the downside protection feature as well as the recognition of the Deferred Payment.
Convertible Bridge Loan Warrants
Together with the issuance of the Convertible Bridge Loans described in Note 6, Convertible Notes, 1,250,000 warrants were issued to lenders (“Convertible Bridge Loan Warrants”). The Convertible Bridge Loan Warrants, which entitle the registered holder to purchase one share of the Company’s common stock, have an exercise price of $1.50 to $2.00 per warrant, became exercisable on the date of the issuance of the warrant, and are set to expire five years from issuance or earlier upon redemption. Additionally, the Convertible Bridge Loan Warrants are exercisable on a cashless basis if mutually agreed upon with the Company. Some of the warrants also have most favored nation status and reset provisions with respect to new warrant issues and existing warrant restructuring. The Convertible Bridge Loan Warrants are liability classified due to the Company not having a sufficient amount of authorized shares to satisfy the hypothetical conversion of the Convertible Bridge Loans as they do not contain a maximum number of shares that they are convertible into. Such warrants are classified to non-current liabilities because their term ends beyond one year from the latest unaudited condensed consolidated balance sheet date.
Convertible 12% Promissory Note Warrants
Together with the issuance of the Convertible 12% Promissory Notes described in Note 6, Convertible Notes, 660,000 warrants were issued to lenders (“Convertible 12% Promissory Note Warrants”). The terms of the Convertible 12% Promissory Note Warrants are identical to the Convertible Bridge Loan Warrants, as they entitle the registered holder to purchase one share of the Company’s common stock, have an exercise price of $2.00 per warrant, became exercisable on the date of the issuance of the warrant, and are set to expire five years from issuance or earlier upon redemption. The Convertible 12% Promissory Note Warrants are liability classified due to the Company having an insufficient amount of authorized shares to satisfy the hypothetical conversion of the Convertible 12% Promissory Notes as they do not contain a maximum number of shares that they are convertible into. Such warrants are classified to non-current liabilities because their term ends beyond one year from the latest unaudited condensed consolidated balance sheet date.
6.Convertible Notes
Legacy Convertible Notes
From November to December 2019 and from March to September 2023, the Company issued convertible promissory notes for aggregate proceeds of $17.3 million, of which $0.4 million were issued to related parties (“Legacy Convertible Notes”). The convertible notes issued during 2019 and 2023 bore an interest rate of 1.7% and 4.6% per year, respectively.
Pursuant to their terms, immediately prior to Closing, all of the Legacy Convertible Notes were converted into 5,579,266 shares of Legacy NKGen common stock, which then converted into 2,278,598 shares of the Company’s common stock at Closing based on the Exchange Ratio.
Senior Convertible Notes
Prior to the Closing, the Company entered into convertible note subscription agreements (“Securities Purchase Agreement”) with NKMAX for total proceeds of $10.0 million, with a four-year term and an interest rate of 5.0% paid in cash semi-annually or 8.0% paid in kind (“Senior Convertible Notes”), which closed on September 29, 2023. Interest began accruing at Closing and is payable semi-annually in arrears, with interest that is paid in kind (if applicable) increasing the principal amount outstanding on each interest payment date. The Company currently expects to make their interest payments in-kind in lieu of periodic cash payments. The Senior Convertible Notes are convertible at any time, in whole or in part, at NKMAX’s option at a conversion price of $10.00 per share of common stock (subject to anti-dilution adjustments in the event of stock splits and the like). The Senior Convertible Notes have a put option which may be exercised by NKMAX 2.5 years after the issuance of the Senior Convertible Notes. No less than six months after exercise of the put option, the Company will be required to repay all principal and accrued interest of the Senior Convertible Notes. Should the put option remain unexercised, the outstanding principal and accrued interest will be due and payable on September 29, 2027. Additionally, as described in Note 5, Warrants, together with the Securities Purchase Agreement, the SPA Warrants were issued to NKMAX. Accordingly, a relative fair value allocation was applied and discount was recognized on the Senior Convertible Notes as set forth in Note 9, Fair Value of Financial Instruments. There are no financial or non-financial covenants associated with the Senior Convertible Notes. During the three months ended March 31, 2024, the Company recorded $0.2 million of interest expense and discount amortization related to the Senior Convertible Notes. As described in Note 8, Related Party Transactions, the Senior Convertible Notes are a related party financial instrument.
The following table presents a reconciliation of the Senior Convertible Notes (in thousands):
| | | | | |
| Senior Convertible Notes |
Balance as of December 31, 2023 | $ | 9,930 |
Amortization of discount | 11 |
Paid-in-kind interest | 206 |
Balance as of March 31, 2024 | $ | 10,147 |
Convertible Bridge Loans
From February to March 2024, the Company issued convertible bridge loans to holders ("2024 Convertible Bridge Loans") and related parties ("2024 Related Party Convertible Bridge Loan"), collectively referred to as ("Convertible Bridge Loans") for total proceeds of $0.3 million and $0.4 million, respectively, with a 20.0% premium due at maturity. The Convertible Bridge Loans mature at the earlier of (i) 60 days from the respective issuance dates, (ii) upon a financing event with third parties exceeding between $5.0 million and $10.0 million, depending on the agreement, (iii) the occurrence of any event of default, or (iv) the acceleration of the short term bridge note. The loans are convertible at any time, in whole or in part, at the holder's option into the Company's common stock at a 15.0% discount to the VWAP 10 days prior to conversion, with the conversion being limited to converting at no more than $2.00 per share. Certain Convertible Bridge Loans also entitle the holder to 7,334 shares of the Company's common stock (“Consideration Shares”). Consideration Shares are liability classified until issuance due to the insufficiency of authorized and unissued shares. Additionally, as described in Note 5, Warrants, concurrently with the Convertible Bridge Loans, the Company issued the Convertible Bridge Loan Warrants to holders which were recognized at fair value of $1.4 million. There are no other financial or non-financial covenants associated with the Convertible Bridge Loans.
The Company recognized a loss of $0.7 million upon issuance of the Convertible Bridge Loans, Convertible Bridge Loan Warrants and Consideration Shares representing the excess of the $1.4 million initial fair value of the Convertible Bridge Loan Warrants over the $0.7 million proceeds received. Accordingly, a discount was recognized on the Convertible Bridge Loans. Refer to Note 9, Fair Value of Financial Instruments.
The Company accretes the balance of the Convertible Bridge Loans on a straight-line basis to its repayment amount through interest expense. During the three months ended March 31, 2024, the Company recorded $0.2 million of interest expense and discount amortization related to the 2024 Convertible Bridge Loans and $0.4 million interest expense and discount amortization related to the 2024 Related Party Convertible Bridge Loan. As of March 31, 2024, $0.2 million remained to be accreted through interest expense on the Convertible Bridge Loans. No interest expense was incurred for the Convertible Bridge Loans during the three months ended March 31, 2023.
In April 2024, the outstanding principal and interest of two of the 2024 Convertible Bridge Loans and the 2024 Related Party Convertible Bridge Loan were repaid in full, for an aggregate payment of $0.3 million and $0.5 million, respectively.
On April 19, 2024, one of the Convertible Bridge Loans was amended to extend the maturity date to be the earliest of (i) 90 days from issuance, (ii) upon a financing event with third parties exceeding $5.0 million, (iii) the occurrence of any event of default, or (iv) the acceleration of the amended and restated short term bridge note. On April 25, 2024, $0.1 million, representing a portion of the outstanding balance was repaid to the lender with less than $0.1 million remaining outstanding under the related Convertible Bridge Loan.
Convertible 12% Promissory Notes
In March 2024, the Company issued convertible 12% promissory notes ("Convertible 12% Promissory Notes") to two holders, one of which is an FPA Investor, with a one year term, for total proceeds of $0.6 million and an original issue discount of $0.1 million. The first 12 months of interest is due and payable as of each respective issuance date. All or any portion of the then outstanding and unpaid principal amount and interest of the Convertible 12% Promissory Notes are convertible at any time at the holder's option into the Company's common stock at a conversion price of $2.00 per share. The Company also issued 500,000 shares of the Company's common stock to holders. Concurrently with the issuance of the Convertible 12% Promissory Notes, the Convertible 12% Promissory Note Warrants were issued to holders, as described in Note 5, Warrants. The Company elected to measure the Convertible 12% Promissory Notes, including accrued interest, using the fair value option under ASC 825, Financial Instruments. Changes in fair value are included in change in fair value of Convertible 12% Promissory Notes on the unaudited condensed consolidated statements of operations. See Note 9, Fair Value of Financial Instruments, for further information. There are no financial or non-financial covenants associated with the Convertible 12% Promissory Notes.
During the three months ended March 31, 2024, the Company recorded a change in fair value of Convertible 12% Promissory Notes of $0.5 million related to the Convertible 12% Promissory Notes. On April 8, 2024 and May 9, 2024 both of the Convertible 12% Promissory Notes were repaid in full for an aggregate repayment of $0.8 million.
7.Debt
Revolving Line of Credit
In June 2023, the Company entered into a $5.0 million revolving line of credit agreement (as amended on September 19, 2023, January 30, 2024 and April 5, 2024) with a commercial bank with a one-year term and an interest rate based on the higher of (i) the one month secured overnight financing rate plus 2.9% or (ii) 7.5%. Issuance fees of $0.1 million were incurred in connection with this revolving line of credit. All outstanding balances under the revolving line of credit were due and payable on June 20, 2024. In April 2024, the agreement was amended to extended the maturity date of the revolving line of credit to September 18, 2024. The revolving line of credit is secured by all of the Company’s assets, including a deed of trust over the Company’s owned real property located in Santa Ana, California. The Company was required to maintain deposits with the lender in an amount of at least $15.0 million from a certain period of time as long as there was a debt balance outstanding. Pursuant to a letter of intent signed in March 2024, in April 2024, the lender subsequently waived the minimum cash deposit requirement in exchange for a $0.1 million payment and the Company's agreement to use the lender as their primary banking relationship. The Company was in compliance with its debt covenants as of March 31, 2024. Additionally, the Company is required to maintain a restricted cash balance of $0.3 million following the issuance. As of March 31, 2024, the interest rate for the revolving line of credit was 8.2%.
Through March 31, 2024, the Company drew down $4.9 million upon the revolving line of credit and no repayments of drawdowns occurred. Interest expense of $0.1 million was incurred upon the revolving line of credit, which was paid in cash during the three months ended March 31, 2024. No interest expense was incurred for the revolving line of credit during the three months ended March 31, 2023 as it was not outstanding.
Related Party Loans
Between August 2019 and April 2023, the Company entered into related party loans with NKMAX (“Related Party Loans”).
From January through April 2023, the Company entered into additional Related Party Loans with NKMAX for aggregate gross proceeds of $5.0 million. These additional Related Party Loans bear an interest rate of 4.6% and mature on December 31, 2024. There are no financial or non-financial covenants associated with the Related Party Loans. The additional Related Party Loans are not convertible into equity.
In connection with the Related Party Loans, interest expenses incurred were $0.1 million and less than $0.1 million for the three months ended March 31, 2024 and 2023, respectively. Related party interest payable amounts recorded to other current liabilities on the unaudited condensed consolidated balance sheets were $0.1 million and $0.2 million as of March 31, 2024 and December 31, 2023, respectively.
Bridge Loans
In March 2024, the Company entered into bridge loan agreements ("Bridge Loans") for total proceeds of $0.2 million, with a premium of 7.5% of the principal, and a maturity date 15 days from funding. The bridge loans were subsequently paid in full on April 10, 2024.
8.Related Party Transactions
Founder Shares
Contemporaneously with the execution of the Merger Agreement, Graf and NKGen entered into an amended and restated sponsor support and lockup agreement (“Amended and Restated Sponsor Support and Lockup Agreement”). In connection with the Amended and Restated Sponsor Support and Lockup Agreement, of the 4,290,375 shares of Graf formerly held by Graf’s sponsor and insiders (“Founder Shares”): (i) 1,773,631 shares were forfeited, (ii) 1,173,631 shares became restricted shares subject to vesting conditions (“Deferred Founder Shares”), and (iii) the remaining 1,343,113 shares are subject to trading restrictions for up to two years and continue to be outstanding and fully vested shares.
Deferred Founder Shares do not have voting rights, do not participate in dividends and are not transferable. During the vesting period of five years from Closing (“Vesting Period”), if the trading price or price per share consideration upon a change in control for common stock is greater than or equal to $14.00 at any 20 trading days in a 30 consecutive trading-day period, then 873,631 Deferred Founder Shares will immediately vest; and if greater than or equal to $20.00 at any 20 trading days in a 30 consecutive trading-day period, then an additional 300,000 Deferred Founder Shares will immediately vest. In the event there is a sale of the Company, then immediately prior to the consummation of such sale, the calculated Acquiror Sale Price, as defined in the agreement, will take into account the number of Deferred Founder Shares that will vest upon a change in control. Upon the expiration of the Vesting Period, unvested Founder Shares will be forfeited and cancelled for no consideration.
All Founder Shares, including Deferred Founder Shares, are equity classified primarily due to terms indexed to the Company’s own stock, including upon a change in control.
Related Party Financial Instruments
The Company’s related party financial instruments include (i) the Founder Shares, including Deferred Founder Shares described above in this Note 8, (ii) the SPA Warrants described in Note 5, Warrants, (iii) the Working Capital Warrants described in Note 5, Warrants, (iv) the Senior Convertible Notes described in Note 6, Convertible Notes, (v) 2024 Related Party Convertible Bridge Loan described in Note 6, Convertible Notes, (vi) select Legacy Convertible Notes described in Note 6, Convertible Notes, (vii) the Related Party Loans described in Note 7, Debt, (viii) the Private Warrants described in Note 5, Warrants, and (ix) 400,000 Convertible Bridge Warrants described in Note 5, Warrants.
Purchases of laboratory supplies
For the three months ended March 31, 2024 and 2023, the Company did not record any research and development expenses associated with the purchase of laboratory supplies from NKMAX. As of March 31, 2024 no amounts payable remained outstanding relating to the purchase of laboratory supplies. As of December 31, 2023, $0.6 million remained outstanding relating to the purchase of laboratory supplies from NKMAX, which were recorded to accounts payable and accrued expenses on the consolidated balance sheets.
9.Fair Value of Financial Instruments
The Company accounts for the fair value of its financial instruments under the framework established by US GAAP which defines fair value and expands disclosures about fair value measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The standard describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value.
The Company’s management used the following methods and assumptions to estimate the fair value of its financial instruments:
Level 1 — Quoted prices in active markets for identical assets or liabilities the Company has the ability to access at the measurement date.
Level 2 — Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of assets or liabilities.
Level 3 — Pricing inputs that are unobservable, supported by little or no market activity and are significant to the fair value of the assets or liabilities.
The carrying amounts of the Company’s financial assets and financial liabilities are considered to be representative of their respective fair values because of the short-term nature of those instruments. The Company does not measure assets at fair value on a recurring basis.
Liabilities measured at fair value on a recurring basis as of March 31, 2024 are as follows (in thousands):
| | | | | | | | | | | | | | | | | | | | | | | |
| Fair Value Measurements at Reporting Date Using |

Total | $ | 34,187 | | | $ | 14 | | | $ | — | | | $ | 34,173 | |
In addition to items that are measured at fair value on a recurring basis, the Company also has liabilities that are measured at fair value on a nonrecurring basis and therefore are not included in the tables above. Liabilities that are measured at fair value on a nonrecurring basis as of March 31, 2024 include the Senior Convertible Notes. The Senior Convertible Notes were determined to be in-scope of ASC 470, Debt. Accordingly, this instrument will not be measured at fair value on a recurring basis as the fair value measurement of this instrument was for purposes of the relative fair value allocation as the Senior Convertible Notes were issued together with the SPA Warrants.
Legacy Convertible Notes
For the three months ended March 31, 2023, the Company recognized $1.5 million of expense associated with the change in fair value of the Legacy Convertible Notes.
The Legacy Convertible Notes converted at Closing on September 29, 2023. The fair value of the notes immediately prior to their conversion at Closing was based upon the fair value of the 2,278,598 shares of the Company’s common stock issued upon their conversion totaling $18.9 million, at a per share value of $8.30 based upon the fair value of the Company’s common stock at Closing.
Convertible 12% Promissory Notes

Change in fair value | $ | 478 | |
Balance as of March 31, 2024 | $ | 728 | |
The fair value of the Convertible 12% Promissory Notes was measured using a binomial lattice model. A binomial stock lattice model generates two probable outcomes of stock price -one up and another down -emanating at each point in time or "node", starting from the valuation date until the maturity date. This lattice generates a distribution of stock price. Based on the stock price at each corresponding node, the value of the Notes was determined by evaluating the optimal decision that a holder and/or the issuer would make to maximize its payoff (the "Decision Tree"). At maturity, the value of the notes was calculated as the maximum between the principal amount and the conversion value. At each node prior to maturity, the lattice model determines whether the notes would be (i) converted by the holder, or (ii) held by the holder, based on the payoff related to each decision. Volatility in the model was estimated from historical equity volatility, median asset volatility of comparable companies, and was adjusted using the Company's capital structure. The cost of debt used in discounting the Notes was estimated based on (i) market yield curve corresponding to the estimated synthetic credit rating of the Company, and (ii) observed market spreads of publicly traded comparable debt with similar credit rating and industry as that of the Company.
The following unobservable assumptions were used in determining the fair value of the Convertible 12% Promissory Notes at March 31, 2024:
| | | | | |
Credit spread | 27.5 | % |
Equity volatility | 45.0 | % |

The fair value of the Private Warrants, Working Capital Warrants, Convertible Bridge Loan Warrants, and Convertible 12% Promissory Note Warrants were measured using a Black-Scholes model. The estimated fair value of the liability classified warrants was determined using Level 3 inputs. Inherent in a Black-Scholes model are assumptions related to expected stock-price volatility, expected life, risk-free interest rate and dividend yield. The Company estimates the volatility of its liability classified warrants based on implied volatility from the Company’s traded warrants and from historical volatility of select peer company’s common stock that matches the expected remaining life of each class of warrants as well as historical volatility of select peer company’s traded options. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a maturity similar to the expected remaining life of each class of warrants. The expected life of each class of warrants is assumed to be equivalent to their remaining contractual term. The dividend rate is based on the historical rate, which the Company anticipates remaining at zero.
The fair value of the PIPE Warrants was valued using level three inputs and was estimated using a Monte Carlo simulation approach. The Company’s common share price was assumed to follow a Geometric Brownian Motion over a period from the Valuation Date to the Expiration Date. The breadth of all possible scenarios was captured in an estimate of volatility, based on comparable companies’ historical equity volatilities, considering differences in their capital structure. For each simulation path, the test price and Reset Price were calculated based on the daily stock price during the measurement period. On each reset date, the downside protection condition was assessed to see if it was met by comparing the test price with the downside protection threshold price. The value of each tranche of warrants was then computed, factoring in any downside protection shares and downside protection cash, if applicable. The average value across this range of possible scenarios, discounted to present using the risk-free rate, was used as the fair value of the PIPE Warrants. The change in fair value of the PIPE Warrants was primarily attributable to select features of the Warrant Subscription Agreements, including strike price resets and downside protection which results in decreased value as the Company’s stock price volatility increases and the stock price declines.
The following unobservable assumptions were used in determining the fair value of the liability classified warrants at March 31, 2024 and December 31, 2023:

The following unobservable assumptions were used in determining the fair value of the PIPE Warrants immediately before and after modification at February 9, 2024:
| | | | | |
Credit spread | 17.8 | % |
Equity volatility | 105.0 | % |
Forward Purchase Derivative Liabilities
The forward purchase derivative liabilities were recognized at Closing on September 29, 2023. The fair value as of March 31, 2024 was $10.1 million.
Refer to Note 4, Private Placements, for a reconciliation of the forward purchase derivative liabilities.
The fair value of the forward purchase derivative liabilities was estimated using a Monte Carlo simulation approach. The Company’s common share price was simulated with daily time steps for a range of various possible scenarios. The breadth of all possible scenarios was captured in an estimate of volatility, based on comparable companies’ historical equity volatilities, considering differences in their capital structure. The simulated prices were compared against the settlement adjustment features of the Forward Purchase Agreements. Under each simulated scenario of future stock price, the Company calculated the value of the forward purchase derivative liability arrangement. The average value across this range of possible scenarios, discounted to present using the risk-free rate, was used as the fair value of the forward purchase derivative liabilities.
The following unobservable assumptions were used in determining the fair value of the forward purchase derivative liabilities at the respective balance sheet and amendment dates:
| | | | | | | | | | | | | | | | | | | | | | | |
| March 31, 2024 | | February 21, 2024 | | January 19, 2024 | | December 31, 2023 |
Dividend yield | 0.0 | % | | 0.0 | % | | 0.0 | % | | 0.0 | % |
Equity volatility | 120.0 | % | | 145.0 | % | | 105.0 | % | | 115.0 | % |
Consideration Shares
The Consideration Shares are recorded at fair value on a recurring basis within Accounts payable and accrued expenses. These shares are liability-classified until issuance and relate to the Convertible Bridge Loans. The liability associated with these Consideration Shares is carried at fair value, demonstrating the obligation to the lenders. The estimated fair value of the Consideration Shares is based on quoted market prices that are readily and regularly available in an active market.
Relative Fair Values
The Convertible 12% Promissory Notes were issued together with the Convertible 12% Promissory Note Warrants. Thus, each instrument was recorded at its fair value, limited to a relative fair value based upon the percentage of its fair value to the total fair value based on the transaction price of $0.6 million at issuance. The Company elected to record the Convertible 12% Promissory Notes at fair value under ASC 825, Financial Instruments.
The relative fair value at initial recognition for the Convertible 12% Promissory Notes and Convertible 12% Promissory Note Warrants was $0.3 million and $0.3 million, respectively. The stand-alone fair value of the Convertible 12% Promissory Notes and Convertible 12% Promissory Note Warrants was $0.7 million and $0.9 million as of March 31, 2024.
Residual Fair Values
The Convertible Bridge Loans were issued together with the Convertible Bridge Loan Warrants. The Convertible Bridge Loan Warrants were recorded at fair value, under ASC 815, Derivatives and Hedging, and the Convertible Bridge Loans were determined to be in-scope of 470, Debt. Accordingly, the Company recorded the fair value of the Convertible Bridge Loan Warrants at issuance, with the residual amount of the proceeds allocated to the convertible debt instrument.
The fair value of the Convertible Bridge Loan Warrants was treated as a discount to the Convertible Bridge Loans, which will be amortized to interest expense over the term of the Convertible Bridge Loans. The stand-alone fair value at initial recognition for the Convertible Bridge Loan Warrants was $1.4 million. Less than $0.1 million residual value allocated to the Convertible Bridge Loans. The Company received total proceeds of $0.7 million from the issuance of the Convertible Bridge Loans. Accordingly, upon issuance, the Company recognized a loss of $0.7 million within loss on issuance of convertible bridge loans unaudited condensed consolidated statements of operations representing the fair value of the Convertible Bridge Loan Warrants over the proceeds received for the issuance of the Convertible Bridge Loans, Convertible Bridge Loan Warrants and Consideration Shares.
10.Stockholder’s Equity
Reverse Recapitalization
As described in Note 2, Summary of Significant Accounting Policies, all historical equity data, including stock option data, in these unaudited condensed consolidated financial statements has been retrospectively adjusted by the Exchange Ratio to reflect the reverse recapitalization that occurred on September 29, 2023.
Common Stock
As of March 31, 2024, the Company had authorized 500,000,000 shares of common stock, par value $0.0001 per share. As of March 31, 2024, 22,388,976 shares of common stock were issued and outstanding, and 477,611,024 shares of common stock were reserved for future issuance.
Preferred Stock
As of March 31, 2024, the Company had authorized 10,000,000 shares of preferred stock, par value $0.0001. As of March 31, 2024, zero shares of preferred stock were issued or outstanding.
Employee Stock Purchase Plan
Upon consummation of the Business Combination, the Company adopted an employee stock purchase plan (“ESPP”). The maximum number of shares of the Company’s common stock that may be issued under the ESPP is 3.0% of the fully diluted common stock of the Company, determined as of immediately following Closing. Such maximum number of shares is subject to automatic annual increases. The Company’s employees and the employees of any designated affiliates may participate in the ESPP. The purchase price of the ESPP shares is 85.0% of the lesser of the fair market value of the Company’s common stock on the first day of an offering or on the applicable date of purchase. As of March 31, 2024, there were no transactions with respect to the ESPP.
2019 Plan
The Company’s 2019 Plan (“2019 Plan”) became effective on October 23, 2019. The 2019 Plan provides for the grant of incentive stock options, non-qualified stock options, stock appreciation rights, restricted stock unit awards and performance share awards to employees, directors, and consultants of the Company. As of March 31, 2024, the Company has only issued stock options.
Stock options granted under the 2019 Plan expire no later than ten years from the date of grant and generally vest over a four-year period, with vesting occurring at a rate of 25.0% at the end of the first and thereafter in 36 equal monthly installments, or in the case of awards granted to board members, on a monthly basis over three or four years. In general, vested options expire if not exercised within three months after termination of service.
2023 Plan
Upon consummation of the Business Combination, the Company adopted the 2023 equity incentive plan (“2023 Plan”). The maximum number of shares of common stock that may be issued under the 2023 Plan is 12.0% of the fully diluted common stock of the Company, determined as of immediately following Closing. Such maximum number of shares is subject to automatic annual increases. Under the 2023 Plan, restricted shares and stock options with service or performance based conditions may be granted to employees and nonemployees.
Upon the effective date of the 2023 Plan, the Company may not grant any additional awards under the 2019 Plan. As of March 31, 2024, certain awards to executives and non-employee directors were granted under the 2023 Plan. Stock options granted under the 2023 Plan expire no later than ten years from the date of grant and generally vest on a monthly basis over three or four years. In general, vested options expire if not exercised within three months after termination of service.
The fair value of each employee and non-employee stock option grant under the 2019 Plan and 2023 Plan are estimated on the date of grant using the Black-Scholes option-pricing model. Due to the Company’s limited operating history and a lack of company-specific historical and implied volatility data, the Company estimated expected volatility based on the historical volatility of a group of similar companies that are publicly traded. The historical volatility data was computed using the daily closing prices for the selected companies’ shares during the equivalent period of the calculated expected term of the stock-based awards. Due to the lack of historical exercise history, the expected term of the Company’s stock options for employees has been determined utilizing the “simplified” method for awards. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected term of the award. The expected dividend yield is zero since the Company has never paid cash dividends and does not expect to pay any cash dividends in the foreseeable future.
A summary of the Company’s stock option activity for the three months ended March 31, 2024 is as follows:
| | | | | | | | | | | |

License Agreements
The Company has entered into exclusive license agreements with NKMAX, as amended in October 2021, April 2023 and August 2023 (“Intercompany License”), pursuant to which the Company acquired certain intellectual property for the development of treatments for cancer and other fields of use. Pursuant to each license agreement, as consideration for an exclusive license to the intellectual property, the Company paid an upfront fee of $1.0 million (“Licensed Technology”), which was recognized as research and development expense in the period paid as the license has no alternative future use.
Additionally, the Company is also required to pay one-time milestone payments for the first receipt of regulatory approval by the Company or any of its affiliates for a Licensed Technology in the following jurisdictions (and amounts): the United States ($5.0 million), the European Union (“EU”) ($4.0 million), and four other countries ($1.0 million each). The Company is obligated to pay a mid-single digit royalty on net sales of Licensed Technology by it, its affiliates or its sublicensees, subject to customary reductions. The Company is also required to pay a percentage of its sublicensing revenue ranging from a low double-digit percentage to a mid-single digit percentage. As of March 31, 2024, the Company has not paid any milestone payments and no sales of Licensed Technology have occurred.
Litigation
The Company is subject to legal proceedings and claims, which arise in the ordinary course of business.
The Company is not subject to any currently pending legal matters or claims that would have a material adverse effect on its financial position, results of operations or cash flows.
In the normal course of business, the Company enters into contracts and agreements that contain a variety of representations and warranties and provide for general indemnifications. The Company’s exposure under these agreements is unknown because it involves claims that may be made against the Company in the future but have not yet been made. The Company accrues a liability for such matters when it is probable that future expenditures will be made, and such expenditures can be reasonably estimated. No amounts were accrued as of March 31, 2024 and December 31, 2023.
15.Income Taxes
The Company is subject to taxation in the U.S. and various state jurisdictions. The Company is not subject to taxation in foreign countries. The Company’s effective tax rate is calculated quarterly based upon current assumptions relating to the full year’s estimated operating results and various tax-related items. Each quarter, an estimate of the annual effective tax rate is updated should the Company revise its forecast of earnings based upon its operating results. If there is a change in the estimated effective annual tax rate, a cumulative adjustment is made. The Company’s effective tax rate was 0.0% for the three months ended March 31, 2024 and 2023.
The difference between the effective tax rate of 0.0% and the U.S. federal statutory rate of 21.0% for the three months ended March 31, 2024 and 2023 was primarily due to changes in deferred tax balances, partially offset by valuation allowances. As of March 31, 2024 and 2023, the Company determined that, based on an evaluation of the Company's history of net losses and all available evidence, both positive and negative, including the Company's latest forecasts and cumulative losses in recent years, it was more likely than not that none or substantially none of the Company's deferred tax assets would be realized and, therefore, the Company continued to record a valuation allowance.

In connection with the three additional tranches, the Company may issue an aggregate of up to 750,000 additional shares of common stock and issue warrants that entitle holders to an aggregate of up to 990,000 shares of common stock at the lender’s sole discretion. Each additional promissory note will have identical terms as the original note, and each additional common stock purchase warrant will have identical terms as the original warrant.
Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.
The following discussion and analysis of our financial condition and results of operations should be read in conjunction with the unaudited condensed consolidated financial statements and related notes included elsewhere in this Quarterly Report on Form 10-Q. In addition to the unaudited condensed consolidated financial information, the following discussion contains forward-looking statements that reflect our plans, estimates, beliefs, and expectations that involve risks and uncertainties. Our actual results and the timing of events could differ materially from those discussed in these forward-looking statements. Factors that could cause or contribute to these differences include those discussed below and elsewhere in this Quarterly Report on Form 10-Q, particularly in Item 1A. “Risk Factors” and “Special Note Regarding Forward-Looking Statements”. Defined terms included below have the same meaning as terms defined and included elsewhere in this Quarterly Report on Form 10-Q.
Overview
We are a clinical-stage biotechnology company focused on the development and commercialization of innovative autologous, allogeneic, and CAR-NK cell therapies utilizing a proprietary SNK platform. Our product candidates are based on a proprietary manufacturing and cryopreservation process which produces SNK cells that have increased activity as compared to the starting population of NK cells, based on the results of in vitro experiments performed by NKMAX, as defined by parameters such as cytotoxicity, cytokine production and activating receptor expression. NKGen believes that SNK cells have the potential to deliver transformational benefits to patients with neurodegenerative diseases, such as Alzheimer’s disease (“AD”) and Parkinson’s disease (“PD”), and cancer.
We were originally incorporated in Delaware on January 28, 2021 under the name Graf Acquisition Corp. IV, a special-purpose acquisition company for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or engaging in any other similar business combination with one or more businesses or entities.
On April 14, 2023, we entered into the Agreement and Plan of Merger by and among Graf, Merger Sub, and Legacy NKGen. Upon consummation of the transactions under the Merger Agreement on September 29, 2023, Merger Sub merged with and into the Company with Legacy NKGen surviving the merger as a wholly owned subsidiary of Graf. In connection with the consummation of the Business Combination, Graf was renamed to “NKGen Biotech, Inc.” and Legacy NKGen changed its name to “NKGen Operating Biotech, Inc.” The common stock and warrants of the combined company began trading on The Nasdaq Stock Market LLC under the symbols “NKGN” and “NKGNW”, respectively, on October 2, 2023.
Throughout the notes to the unaudited condensed consolidated financial statements, unless otherwise noted or otherwise suggested by context, the “Company”, “we”, “us”, “our” refers to Legacy NKGen prior to the consummation of the Business Combination, and the Company after the consummation of the Business Combination.
The Business Combination
In connection with the Business Combination, several financial instruments were issued. This included the Senior Convertible Notes, the SPA Warrants, the PIPE Warrants, and the Forward Purchase Agreements. In addition, several pre-existing financial instruments of Graf were deemed issued pursuant to the reverse recapitalization treatment of the Business Combination, including Graf’s remaining public shares, the Private Warrants, the Public Warrants, and the Working Capital Warrants. Furthermore, we incurred transaction costs, certain Founder Shares were terminated or placed under vesting conditions, our Legacy Convertible Notes converted, all assets and liabilities of Graf were combined with the assets and liabilities of NKGen on a historical cost basis, all of Legacy NKGen’s common stock and stock options were exchanged for common stock of the Company based upon the Exchange Ratio, among other material events. Refer to Note 3, Reverse Recapitalization, of the unaudited condensed consolidated financial statements for details surrounding the Business Combination.
Business Highlights
Our goal is to bring transformative Natural Killer (“NK”) cell therapies to patients with both neurodegenerative and oncological diseases and thereby realize the potential of our extensive NK cell expertise. On October 14, 2022, we received investigational new drug (“IND”) clearance from the U.S. Food and Drug Administration (“FDA”) for SNK02 allogenic NK cell therapy for solid tumors. On October 20, 2023, we received IND clearance from the FDA for SNK01 in AD. On December 21, 2023, we received the No Objection Letter from Health Canada for our clinical trial application of SNK01 in AD. On December 28, 2023, we dosed our first participant in the US on the SNK01-AD01 clinical trial. During 2024 and beyond, we intend to (i) advance the clinical development of SNK01 and continue enrolling the Phase I/IIa trial in the United States and Canada for AD, and (ii) complete the Phase I trial with SNK02 in refractory solid tumors. We also intend to conduct a trial in PD, to evaluate the expansion into other neurodegenerative diseases, accelerate development in oncology through strategic collaborations, and continue investment in our manufacturing technology.
NKGen presented its Phase I clinical trial data at the 16th Annual Clinical Trials on Alzheimer’s Disease conference on October 25, 2023. Ten AD patients from the first three cohorts in our ten-week Phase I dose escalation clinical trial were analyzed. NK cells were successfully activated and expanded for 100% of the patients in the trial. No treatment-related adverse events were observed. One week after the last dose (Week 11), 30% of patients showed clinical improvement on the AD composite score (“ADCOMS”) compared to baseline, 60% of patients showed a stable ADCOMS score compared to baseline, and 50–70% of patients were stable or improved on the clinical dementia rating sum of boxes (“CDR-SB”), Alzheimer’s Disease assessment scale-cognitive subscale (“ADAS-Cog”) and/or mini-mental state examination (“MMSE”) scores. One patient’s score showed a switch from a moderate classification on the ADCOMS to a mild classification. Twelve weeks after the last dose (Week 22), 44–89% of patients remained stable or improved in all cognitive scores compared to Week 11, and 50% of patients’ ADCOMS scores remained stable compared to Week 11. Based on the CSF biomarker data, SNK01 given via IV appears to cross the blood-brain barrier to reduce CSF pTau181 levels and neuroinflammation, as measured by GFAP; this effect appears to be persistent at Week 22. Our goal is to utilize our extensive NK cell expertise and bring transformative NK cell therapies to patients with neurodegenerative disease.
Factors Affecting Our Performance
Our operations to date have been limited to business planning, raising capital, developing, and identifying NK cell therapies utilizing our SNK platform, clinical studies, and other research and development activities. We have never been profitable from operations and our net losses were $5.4 million and $8.3 million for the three months ended March 31, 2024 and 2023, respectively. As of March 31, 2024, our accumulated deficit was $167.5 million. We expect to continue incurring significant expenses and operating losses for at least the next several years associated with our ongoing activities as we:
•initiate and complete nonclinical studies and clinical trials for our product candidates;
•contract to manufacture and perform additional process development for our product candidates;
•continue research and development efforts to build our pipeline beyond the current product candidates;
•maintain, expand, and protect our intellectual property portfolio;
•hire additional clinical, quality control, scientific, and management personnel;
•add operational and financial personnel to support our product development efforts and planned future commercialization; and
•add operational and administrative capabilities applicable to operating as a public company.
We do not expect to generate any revenues from product sales unless and until we successfully complete development and obtain regulatory approval for one or more product candidates, which will not be for many years, if ever. Accordingly, until such time as we can generate significant revenue from sales of our product candidates, if ever, we expect to finance our cash needs through equity offerings, debt financings or other capital sources, including from related parties, and potentially grants, collaborations, licenses, or other similar arrangements. However, we may be unable to raise additional funds or enter into such other arrangements when needed on favorable terms or at all. Our failure to raise capital or enter into such other arrangements when needed would have a negative impact on our financial condition and could force us to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market product candidates or to our platform technologies that we would otherwise prefer to develop and market ourselves.
We do not currently have, and do not currently expect to have, sufficient funds to service our operations and our expenses and other liquidity needs and will require additional capital immediately. In addition, we have expressed substantial doubt as to our ability to continue as a going concern. There can be no assurance that we will be able to timely secure such additional funding on acceptable terms and conditions, or at all. If we are unable to raise sufficient capital immediately, we will not have sufficient cash and liquidity to finance our business operations and make required payments and may be required to delay, limit, curtail or terminate our product development or may be forced to cease operations or file for bankruptcy protection.
Key Components of Results of Operations
Revenues
We do not currently have any products approved for sale and have not recognized any product revenue to date. In the future, we may generate revenue from a combination of sources, including, without limitation, product sales, payments from licenses, milestone payments or collaboration arrangements. If we fail to achieve clinical success or obtain regulatory approval of any of our product candidates, our ability to generate future revenue will be limited.
There was no revenue recognized during the three months ended March 31, 2024 and the three months ended March 31, 2023.
Costs and Expenses
Research and Development Expenses
We primarily focus our resources on research and development activities, including the conduct of preclinical studies, product development, regulatory support, and clinical trials for our product candidates. Our research and development expenses consist of:
•employee-related expenses, including salaries, benefits, taxes, travel, and stock-based compensation expense, for personnel in research and development functions;
•expenses related to process development and production of product candidates;
•costs associated with preclinical activities and regulatory operations, including the costs of acquiring, developing, and manufacturing research material;
•clinical trials and activities related to regulatory filings for our product candidates; and
•allocation of facilities, overhead, depreciation, and amortization of laboratory equipment and other expenses.
We expect our direct and indirect research and development expenses to increase in the future as we continue to develop our platform and product candidates.
The successful development of our platform and product candidates is highly uncertain. The process of conducting the necessary preclinical and clinical research to obtain regulatory approval is costly and time consuming. At this time, we cannot reasonably estimate the nature, timing, or costs of the efforts necessary to finish developing any of our product candidates or the period in which material net cash, if any, from these product candidates may commence. This is due to the numerous risks and uncertainties associated with developing therapeutics and will depend on a variety of factors, including, but not limited to:
•the scope, rate of progress, expense, and results of clinical trials;
•the scope, rate of progress and expense of process development and manufacturing;
•preclinical and other research activities; and
•the timing of regulatory approvals.
Research and development expenses consist of expenses incurred while performing research and development activities to discover and develop our product candidates. Direct research and development costs include external research and development expenses incurred under agreements with contract research organizations, consultants and other vendors that conduct our preclinical and clinical activities, expenses related to manufacturing our product candidates for preclinical and clinical studies, laboratory supplies and license fees. Indirect research and development costs include personnel-related expenses, consisting of employee salaries, payroll taxes, bonuses, benefits, and stock-based compensation charges for those individuals involved in research and development efforts. Costs incurred in our research and development efforts are expensed as incurred.
We typically use employee, consultant, facility, equipment and certain supply resources across our research and development programs. We track outsourced development costs by product candidate or development program, but we do not allocate personnel costs, other internal costs or certain external consultant costs to specific product candidates or development programs. These costs are included in indirect research and development expenses. All direct research and development expenses during the three months ended March 31, 2024 and 2023 relate to SNK01 and SNK02.
General and Administrative Expenses
General and administrative expenses consist primarily of personnel-related expenses for executives, human resources, finance, and other general and administrative employees, including salary and stock-based compensation, professional services costs and allocation of facility and overhead costs.
We anticipate that general and administrative expenses will increase in the future in connection with the ongoing costs of operating as a public company, including expanding headcount and increased fees for directors and outside advisors. We expect to incur significant costs to comply with corporate governance, internal controls, and similar requirements applicable to public companies. Additionally, we expect to incur increased costs associated with establishing sales, marketing and commercialization functions prior to any potential future regulatory approvals or commercialization of our product candidates.
Interest Expense
For the three months ended March 31, 2024, interest expense primarily consists of interest incurred for our revolving line of credit, Convertible Bridge Loans, Bridge Loans, and Senior Convertible Notes.
For the three months ended March 31, 2023, interest expense primarily consists of interest incurred associated with our Related Party Loans.
Interest expense associated with both the Legacy Convertible Notes and Convertible 12% Promissory Notes, which we have elected to account for at fair value, is included in the change in fair value for such notes.
Loss on Amendment of Forward Purchase Contracts
On December 26, 2023, in exchange for $0.5 million of consideration, the FPA Amendment was executed with an FPA Investor, which impacted the cash proceeds we may receive under the forward purchase agreement. As a result of the FPA Amendment, the maximum cash proceeds we could receive under the forward purchase contract, reflected in the subscription receivable balance, was lowered. The reduction in the subscription receivable was caused by (i) the Amended Reset Price, which reduced the maximum price per FPA Share we could receive (initially, $10.44 per share), (ii) the re-designation of 200,000 FPA Shares to Bonus Shares, reducing the total quantity of FPA Shares, and (iii) the Amended Prepayment Shortfall, which increased the prepayment shortfall amount. We do not receive any consideration for sales or settlements of Bonus Shares or Shortfall Sales. The proceeds from the sale of FPA Shares by FPA Investors to third parties are required to be treated as a reduction to the prepayment shortfall until no balance remains, at which point, the Company may start to receive proceeds from such sales of the FPA Shares. The Company recognized a corresponding reduction to the forward purchase derivative liabilities on the amendment date as it represents the portion of the subscription receivable that may be released to the FPA Investors rather than to us.
From January to February 2024, in exchange for $1.0 million of consideration, the 2024 FPA Amendments were executed with certain FPA Investors, which further impacted the cash proceeds we may receive under the forward purchase agreement. As a result of the 2024 FPA Amendments, the subscription receivable balance was further lowered due to (i) the 2024 Amended Reset Price for one of the FPA Investors, which reduced the maximum price per FPA Share we could receive (initially, $10.44 per share), (ii) the re-designation of 200,000 FPA Shares to Bonus Shares, reducing the total quantity of FPA Shares, and (iii) the 2024 Amended Prepayment Shortfall, which increased the prepayment shortfall amount. The Company recognized a corresponding reduction to the forward purchase derivative liabilities on the amendment date as it represents the portion of the subscription receivable that may be released to the FPA Investors rather than to us.
Loss on Issuance of Convertible Bridge Loans
From February to March 2024, in exchange for $0.7 million of consideration, the Convertible Bridge Loans were issued to holders with a 20.0% premium due at maturity. Together with the issuance of the Convertible Bridge Loans, the Consideration Shares and Convertible Bridge Loan Warrants were issued to lenders. The fair value of wthe Convertible Bridge Loan Warrants is recognized as a debt discount. The loss on issuance represents the excess of the fair value of the Convertible Bridge Loan Warrants over the proceeds received from the issuance of the convertible loans.
Gain on Amendment of PIPE Warrant Agreement
In February 2024, the PIPE Warrant Amendment accelerated the share conversion provision of the Warrant Subscription Agreement. The gain on the amendment represents the cash proceeds and the change in fair value of the PIPE Warrant derivative liability in connection with the PIPE Warrant Amendment.
Change in Fair Value of the Forward Purchase Derivative Liabilities
The change in fair value of the forward purchase derivative liabilities represents the recognition of changes in fair value of the forward purchase derivative liabilities, which are recognized in net losses on a quarterly basis at each balance sheet date.
Change in Fair Value of Derivative Warrant Liabilities
The change in fair value of derivative warrant liabilities represents the recognition of changes in the fair value of the Private Warrants, Working Capital Warrants, PIPE Warrants, Convertible Bridge Loan Warrants, and Convertible 12% Promissory Note Warrants, which are recognized in net losses on a quarterly basis at each balance sheet date.
Change in Fair Value of Convertible 12% Promissory Notes
The change in fair value of the Convertible 12% Promissory Notes represents the recognition of changes in fair value of the Convertible 12% Promissory Notes, which are carried at fair value and related changes are recognized in net losses on a quarterly basis at each balance sheet date. The Convertible 12% Promissory Notes were issued in March and April 2024.
Change in Fair Value of Legacy Convertible Notes
Change in fair value of the Legacy Convertible Notes for the three months ended March 31, 2024 and 2023, consists of gains or losses on the Legacy Convertible Notes, previously included within other expenses. Immediately prior to the Closing, all Legacy Convertible Notes were converted into shares of Legacy NKGen common stock, which then converted into our Common Stock at Closing. Senior Convertible Notes are not carried at fair value and, thus, are not included within this financial statement caption.
Other Income (Loss), Net
Other income (loss), net primarily consists of the loss on disposal of fixed assets, and the change in fair value of the Consideration Shares for the three months ended March 31, 2024. Other income (loss), net includes sublease income and other expense for the three months ended March 31, 2023.
Provision for Income Taxes
We are subject to U.S. federal and state income taxes based on enacted rates, as adjusted for allowable credits, deductions, uncertain tax positions, changes in deferred tax assets and liabilities and changes in tax laws.
Provision for income taxes primarily relates to changes in deferred taxes, partially offset by valuation allowances.

Total research and development expenses decreased by $0.4 million, or 10%, for the three months ended March 31, 2024 as compared to the three months ended March 31, 2023. The decrease was primarily attributable to a decrease in total indirect research and development expenses of $0.3 million, or 8%.
The decrease of $0.1 million in direct research and development expenses for the three months ended March 31, 2024 as compared to the three months ended March 31, 2023 was primarily attributable to the decrease of $0.1 million, or 32%, in clinical costs.
The decrease in total indirect research and development expenses for the three months ended March 31, 2024 as compared to three months ended March 31, 2023 was primarily attributable to a $0.4 million, or 17%, decrease in personnel-related costs, and a less than $0.1 million, or 4%, decrease in research and development supplies and services, offset by a $0.1 million, or 46%, increase in allocated facility, equipment, and other expenses.
The decrease in personnel-related costs for the three months ended March 31, 2024 as compared to the three months ended March 31, 2023 was primarily attributable to a $0.2 million, or 10%, decrease in compensation costs for research and development personnel and a $0.2 million, or 56%, decrease in stock-based compensation expense as a result of stock option grants that were granted and subject to vesting from immediately upon grant to four years during the first quarter of 2023, where as no such options were granted to research and development personnel during the first quarter of 2024.
The decrease in research and development supplies and services for the three months ended March 31, 2024 as compared to the three months ended March 31, 2023 was primarily attributable to a $0.1 million, or 21%, decrease in laboratory supply costs due to decreased purchases of research and development materials during the three months ended March 31, 2024 as compared to the three months ended March 31, 2023. The expenses were offset by a $0.1 million, or 19%, increase in professional fees due to increased consulting and regulatory affairs costs.
The increase in allocated facility, equipment, and other expenses for the three months ended March 31, 2024 as compared to the three months ended March 31, 2023 was primarily attributable to a $0.1 million, or 50%, increase in depreciation expense and a less than $0.1 million increase in 401K expenses for research and development personnel.
General and Administrative Expenses
General and administrative expenses increased by $1.2 million, or 37%, for the three months ended March 31, 2024 as compared to the three months ended March 31, 2023. The increase was primarily attributable to an increase in professional fees of $1.2 million due to increases in legal, consultant, and accounting costs incurred in relation to being a public company, an increase of $0.1 million in taxes and licenses and an increase in stock-option compensation expense of less than $0.1. The increase was offset by a decrease in salaries of $0.3 million.
Interest Expense
Interest expense increased by $1.0 million the three months ended March 31, 2024 as compared to the three months ended March 31, 2023. The increase was primarily attributable to increase in interest expense related to the Convertible Bridge Loans, Bridge Loans, Related Party Loans, revolving line of credit, and Senior Convertible Notes.
Interest expense associated with the Convertible Bridge Loans, Senior Convertible Notes, and revolving line of credit were $0.6 million, $0.2 million, and $0.1 million, respectively during the three months ended March 31, 2024. None of which were issued or outstanding as of March 31, 2023.
Loss on Amendment of Forward Purchase Contracts
The loss on amendment of forward purchase contracts of $0.4 million was recorded in the three months ended March 31, 2024. The loss on amendment of forward purchase contracts represents the $2.8 million reduction of the subscription receivable, partially offset by the corresponding reduction in the forward purchase derivative liabilities of $1.4 million and the $1.0 million of consideration received by the Company. There were no forward purchase contracts recorded as of March 31, 2023.
Loss on Issuance of Convertible Bridge Loans
The loss on issuance of the Convertible Bridge Loans of $0.7 million was recorded in the three months ended March 31, 2024, primarily attributable to the excess fair value of the Convertible Bridge Loan Warrants of $1.4 million over proceeds of $0.7 million received as part of the transaction. No residual value was attributable to the Convertible Bridge Loans at issuance. There were no Convertible Bridge Loans recorded as of March 31, 2023.
Gain on Amendment of PIPE Warrant Agreement
The gain on amendment of the PIPE warrant agreement of $0.7 million was recorded in the three months ended March 31, 2024. The gain on the amendment represents the cash proceeds of $0.3 million and the reduction in fair value of the PIPE Warrant derivative liability of $0.4 million in connection with the PIPE Warrant Amendment. The reduction in fair value was primarily related to the Deferred Payment and removal of downside protection cash provisions in connection with the amendment. There were no PIPE Warrants recorded as of March 31, 2023.
Change in Fair Value of Forward Purchase Derivative Liabilities
The change in fair value of forward purchase derivative liabilities of $0.5 million was recorded in the three months ended March 31, 2024. The change in fair value was attributed to the recognition of gains and losses resulting from the remeasurement of the fair value of the forward purchase derivative liabilities at each balance sheet date. The reduction in fair value was primarily related to the effect of share price reduction as compared to the initial issuance, which decreased the potential amounts to be received under the subscription receivable, which has a corresponding reduction in the fair value of the forward purchase derivative liabilities. There were no forward purchase derivative liabilities recorded as of March 31, 2023.
Change in Fair Value of Derivative Warrant Liabilities
The change in fair value of the derivative warrant liabilities of $3.7 million was recorded in the three months ended March 31, 2024. The change represents the recognition of gains and losses resulting from the remeasurement of the fair value of the Private Warrants, Working Capital Warrants, PIPE Warrants, Convertible Bridge Loan Warrants and Convertible 12% Promissory Note Warrants at each balance sheet date. The change in fair value of the derivative warrant liabilities is primarily related to the decrease in fair value of the PIPE Warrants of $5.2 million, partially offset by increases in fair value of the Convertible 12% Promissory Note Warrants, Private Warrants, Convertible Bridge Loan Warrants, and of $0.6 million, $0.4 million, and $0.4 million, respectively.
The reduction in the fair value of the PIPE Warrants was primarily attributable to decreases in share price during the three months ended March 31, 2023. The increases in fair value of the Private Warrants, Convertible Bridge Loan Warrants, and Convertible 12% Promissory Note Warrants were primarily attributable to increases in stock price volatility during the three months ended March 31, 2024. There were no derivative warrant liabilities recorded as of March 31, 2023.
Change in Fair Value of Convertible 12% Promissory Notes
The change in fair value of the Convertible 12% Promissory Notes of $0.5 million was recorded during the three months ended March 31, 2024, compared to no change in fair value during the three months ended March 31, 2023. The $0.5 million change in the Convertible 12% Promissory Notes was primarily related to their standalone value at March 31, 2024 in excess of the proceeds allocated on a relative fair value basis at issuance. There were no Convertible 12% Promissory Notes recorded as of March 31, 2023.
Change in Fair Value of Legacy Convertible Notes
The change in fair value of Legacy Convertible Notes was $1.5 million for the three months ended March 31, 2023. The change is attributed to the conversion of the Legacy Convertible Notes upon Closing (exclusive of increases in fair value due to issuances). Changes in fair value were as a result of expected conversion prices, probabilities of conversion, and the recognition of accrued interest from issuance during the periods leading to conversion. There were no outstanding Legacy Convertible Notes for the three months ended March 31, 2024.
Other Income (Loss), Net
Other income (loss), net, decreased by less than $0.1 million, for the three months ended March 31, 2024 as compared to the three months ended March 31, 2023. The increase was primarily attributable to the expiration of the sublease arrangement prior to July 2023 for which NKGen was the lessor, partially offset by the less than $0.1 million increase in fair value of liability classified common stock issued during the three months ended March 31, 2024.
Liquidity and Capital Resources
Funding Requirements and Going Concern
We have incurred operating losses and negative cash flows from operations since inception. We are still in our early stages of development and expect to continue to incur significant expenses and operating losses for the foreseeable future as we continue our research and preclinical studies and clinical trials, including our Phase 1 and Phase 1/2 clinical trials and anticipated Phase 2 clinical trials, expand our pipeline or scope of our current studies for our product candidates, initiate additional preclinical or other studies or clinical trials for our product candidates, change or add additional manufacturers or suppliers, seek regulatory and marketing approvals for any of our product candidates that successfully complete clinical studies, if any, acquire or in-license other product candidates and technologies, maintain, protect and expand our intellectual property portfolio, attract and retain skilled personnel, and experience any delays or encounter issues with any of the above.
Until such time as we can generate substantial product revenue, if ever, we expect to finance our cash needs through a combination of equity and debt financings, or other capital sources, including with related parties. To the extent that we raise additional capital through the future sale of equity or debt, the ownership interest of our stockholders will be diluted. The terms of these securities may include liquidation or other preferences that adversely affect the rights of our existing common stockholders. If we raise additional funds through collaboration agreements, marketing agreements, or licensing arrangements, we may have to relinquish valuable rights to our technologies, future revenue streams or product candidates on terms that may not be favorable to us. If we are unable to raise sufficient funds through equity or debt financings, we may be required to delay, limit, curtail or terminate our product development or future commercialization efforts or may be forced to cease operations or file for bankruptcy protection. Additionally, we may never become profitable, or if we do, may not be able to sustain profitability on a recurring basis.
As of each of the periods ended March 31, 2024 and December 31, 2023, we had cash and cash equivalents of less than $0.1 million and working capital deficits of approximately $35.9 million and $37.5 million, respectively. We have incurred substantial transaction expenses in connection with the Business Combination. As of March 31, 2024, we had accrued approximately $15.3 million in accounts payable and accrued expenses, including the transaction expenses from the Business Combination and our ongoing business operations. However, we continue to have substantial transaction expenses accrued and unpaid subsequent to the Business Combination. Furthermore, we have and expect to incur additional expenses in connection with transitioning to, and operating as, a public company. Additionally, we have $21.7 million in outstanding debts as of March 31, 2024, inclusive of our revolving line of credit, debts with related parties, and debts due within less than one year following March 31, 2024. In April 2024, the Company issued additional debts of $7.5 million in the form of a $5.0 million convertible secured promissory note, $1.5 million of additional Convertible 12% Promissory Notes and $1.0 million zero coupon convertible promissory notes.
Our revolving line of credit, as amended, with East West Bank, which is secured by all of our assets, required us to maintain a minimum cash balance of $15.0 million with the bank by a certain period of time as long as there was an outstanding balance under the revolving line of credit. Such cash balance requirement has been contractually waived by East West Bank prior to March 31, 2024, and pursuant to an amendment entered into on April 5, 2024, East West Bank has agreed to replace such minimum cash balance requirement with a covenant to use East West Bank as the Company's only commercial bank for cash deposits and extend the maturity date to September 18, 2024. See “Risk Factors — Risks Related to Our Financial Position — The East West Bank Loan Agreement and Equity and Business Loan Agreement (as defined below) provide each lender with a security interest in all of our assets, and contain financial covenants and other restrictions on our actions that may limit our operational flexibility or otherwise adversely affect our results of operations” for more details.
We entered into certain forward purchase arrangements with various investors in order to facilitate the consummation of the Business Combination. However, in accordance with such Forward Purchase Agreements, the funds raised in connection with such transactions were placed into escrow accounts and not received by the Company at the Closing of the Business Combination. As of March 31, 2024, we had settled substantially all amounts previously outstanding under two of the Forward Purchase Agreements and related amendments for aggregate proceeds of $2.4 million. There is no guarantee that the Company will receive substantial amounts of additional funds or any in connection with the outstanding Forward Purchase Agreements. In addition, we may be required to pay cash or issue additional shares of our common stock to holders of the PIPE Warrants under certain circumstances, which could adversely affect our financial position and results of operations. See “Risk Factors — Risks Related to Ownership of Our Securities — We may not receive any cash proceeds from the exercise of certain outstanding warrants and we may be required to pay cash or issue additional shares of common stock under certain circumstances” for more details.
We have considered that our long-term operations anticipate continuing net losses and the need for potential debt or equity financing. However, there can be no assurances that additional funding or other sources of capital will be available on terms acceptable to us, or at all. If additional capital is not secured when required, we may need to delay or curtail our operations until such funding is received. If we cannot expand our operations or otherwise capitalize on our business opportunities because we lack sufficient capital, our business, financial condition, and results of operations could be materially and adversely affected.
We do not currently have, and do not currently expect to have, sufficient funds to service our operations and our expenses and other liquidity needs and will require additional capital immediately. In addition, we have expressed substantial doubt as to our ability to continue as a going concern. There can be no assurance that we will be able to timely secure such additional funding on acceptable terms and conditions, or at all. If we are unable to raise sufficient capital immediately, we will not have sufficient cash and liquidity to finance our business operations and make required payments and may be required to delay, limit, curtail or terminate our product development or may be forced to cease operations or file for bankruptcy protection.
Because the proceeds from our financing arrangements will not be adequate to cover our accrued and unpaid expenses and provide the cash and liquidity necessary to operate our business, we continue to seek opportunities for raising additional funds through potential alternatives, which may include, among other things, the issuance of equity, equity-linked, and/or debt securities, debt financings, forward purchase arrangements or other capital sources. However, we may not be successful in securing additional financing on a timely basis, on acceptable terms and conditions or at all. In addition, substantial doubt about our ability to continue as a going concern may cause investors or other financing sources to be unwilling to provide funding to us on commercially reasonable terms, if at all. If sufficient funds are not available, we will have to delay, reduce the scope of, or eliminate some of our business activities, including related operating expenses, which would adversely affect our business prospects and our ability to continue our operations and would have a negative impact on our financial condition and ability to pursue our business strategies. In addition, we may have to liquidate our assets and may receive less than the value at which those assets are carried on our financial statements, and/or seek protection under Chapters 7 or 11 of the United States Bankruptcy Code which could potentially cause us to cease operations and result in a complete or partial loss for our investors.
As a result of these conditions, we have concluded that there is substantial doubt over our ability to continue as a going concern as conditions and events, considered in the aggregate, indicate that we are currently unable to meet our obligations as they become due and expect to be unable to meet our obligations within one year after the date that the financial statements are issued. The accompanying financial statements have been prepared on a going concern basis, which contemplates the realization of assets and settlement of liabilities and commitments in the normal course of business. The financial information and financial statements do not include any adjustments that might be necessary if the Company is unable to continue as a going concern. Our ability to continue as a going concern is dependent upon our ability to raise additional funds and financing. We will need to raise additional capital immediately to continue operations based on our current business plan, and expectations and assumptions considering current macroeconomic conditions. There can be no assurance that we will be able to secure such additional funding on acceptable terms and conditions, or at all. If we cannot obtain sufficient capital immediately, we will not have sufficient cash flows and liquidity to finance our business operations as currently contemplated and we may need to substantially alter, or possibly even discontinue, our operations. In the event of a bankruptcy proceeding or insolvency, or restructuring of our capital structure, our stockholders could suffer a total loss of their investment.
Sources of Liquidity
To date, we have funded our operations primarily with the net proceeds from the issuance of various convertible note financings, Bridge Loans, Related Party Loans, draws upon a revolving line of credit, the issuance and sale of equity securities, warrants, private placements, and proceeds from the Business Combination. As of March 31, 2024, we have cash and cash equivalents of less than $0.1 million and restricted cash of $0.3 million. In the future, we expect to finance our cash needs through a combination of equity and debt financings, including with related parties.
Senior Convertible Notes
We entered into convertible note subscription agreements with NKMAX for total proceeds of $10.0 million upon Closing with a four-year term and for which we expect to make interest payments of 8.0% paid in kind rather than 5.0% paid in cash semi-annually.
Legacy Convertible Notes
From November to December 2019 and from March to September 2023, the Company issued the Legacy Convertible Notes for an aggregate proceeds of $17.3 million, of which $0.4 million were issued to related parties.
The Closing of the Business combination triggered the conversion of the Legacy Convertible Notes at their contractual discounts. Pursuant to their terms, all of the Legacy Convertible Notes were converted into 5,579,266 shares of Legacy NKGen common stock, which then converted into 2,278,598 shares of common stock at Closing based on the Exchange Ratio.
Revolving Line of Credit
In June 2023, we entered into a $5.0 million revolving line of credit agreement with a commercial bank with a one year term. The revolving line of credit is secured by all of our assets, including a deed of trust over our owned real property located in Santa Ana, California. Additionally, we are required to maintain a restricted cash balance of $0.3 million following the issuance. Through March 31, 2024, we drew down $4.9 million upon the revolving line of credit and no repayments of drawdown occurred.
Related Party Loans
Between August 2019 and April 2023, we entered into Related Party Loans with NKMAX.
In December 2022, the then-outstanding aggregate Related Party Loans’ principal and interest of $66.1 million was converted into 6,943,789 shares of common stock (after the application of the Exchange Ratio) which was recognized as a capital contribution for the year ended December 31, 2022.
From January through April 2023, we entered into additional Related Party Loans with NKMAX for aggregate gross proceeds of $5.0 million. These additional Related Party Loans bear an interest rate of 4.6% and mature on December 31, 2024. There are no financial or non-financial covenants associated with the Related Party Loans. The additional Related Party Loans are not convertible into equity.
Convertible Bridge Loans
From February to March 2024, the Company issued Convertible Bridge Loans for total proceeds of $0.6 million, inclusive of $0.4 million issued to a related party with a 20.0% premium due at maturity. The loans are convertible at any time, in whole or in part, at the holder's option into the Company's common stock at a 15.0% discount to the 10 day VWAP prior to conversion, with the conversion being limited to converting at no more than $2.00 per share. To date, of the $0.9 million total repayment amount, $0.8 million was repaid and less than $0.1 million remained outstanding.
Bridge Loans
On March 7, 2024, we entered into two bridge loan agreements for total proceeds of $0.2 million that mature 15 days from issuance, with a 7.5% premium due at maturity. Both loans were repaid upon closing of the convertible secured promissory note.
Convertible 12% Promissory Notes
From March to May 2024, we entered into several convertible 12% promissory note agreements for $1.5 million with a one year term, issued at a 10.0% discount. The lenders retain the option to convert any or all outstanding and unpaid principal amount and interest into shares of the Company's common stock from the date of issuance until the maturity date. One of the Convertible 12% Promissory Notes was repaid and settled in April 2024 for $0.4 million. In May, another was repaid in full for $0.4 million. To date, $0.7 million related to the Convertible 12% Promissory Notes was repaid.
Convertible Secured Promissory Note
On April 5, 2024, the Company entered into a Convertible Secured Promissory note agreement for $5.0 million with an interest rate of the one month secured overnight financing rate plus 2.9% payable in cash in arrears on a monthly basis, with payments commencing one month from issuance which will mature on October 4, 2026. The convertible secured promissory note is secured by a second lien on the Company’s owned real property located in Santa Ana, California and subordinate to the $5.0 million revolving line of credit.
Private Placement
From the three months ended March 31, 2024, the Company received total proceeds of $1.5 million in connection with the FPA Amendment in December 2023 and the 2024 FPA Amendments in January and February 2024. We received additional proceeds of $0.9 million from sales of FPA Shares settling all outstanding obligations as of March 31, 2024 under certain of our Forward Purchase Agreements.
SPA Warrants
We did not receive any proceeds from the SPA Warrants upon the issuance at Closing but may receive proceeds upon their exercise.
PIPE Warrants
Prior to the Closing, we entered into warrant subscription agreements with certain investors, which closed on September 29, 2023. Pursuant to the Warrant Subscription Agreements, the Warrant Investors purchased an aggregate of 10,209,994 warrants, at a purchase price of $1.00 per warrant for total proceeds of $10.2 million.
On February 9, 2024, we amended our Warrant Subscription Agreement with a Warrant Investor to, among other things, grant the Warrant Investor, (i) the right to exchange each PIPE Warrant for a newly registered share, effectively waiving the original strike price, (ii) a “Most Favored Nation” status with respect to warrant restructuring such that they may amend the terms upon the Company executing a similar transaction with more favorable terms for so long as any subscription warrants remain outstanding, and (iii) certain registration rights. In exchange, we received an upfront cash payment of $0.3 million during the three months ended March 31, 2024 and the right to receive a second cash payment of up to $0.3 million based on the trailing 5-day VWAP following the effective registration of the shares, which has not yet been achieved.
All other PIPE Warrant arrangements remained unchanged.
Working Capital Warrants
We did not receive any proceeds from the Working Capital Warrants upon the issuance at Closing but may receive proceeds upon their exercise.
Public Warrants
We did not receive proceeds from the Public Warrants at Closing but may receive proceeds upon their exercise.
Private Warrants
Concurrently with Graf’s IPO, Graf issued 4,721,533 warrants to Graf Acquisition Partners IV LLC. We did not receive any additional proceeds from the Private Warrants at Closing but may receive proceeds upon their exercise.
Convertible Bridge Loans Warrants
We did not receive proceeds from the Convertible Bridge Loans Warrants upon issuance but may receive proceeds upon their exercise.
Convertible 12% Promissory Notes Warrants
We did not receive proceeds from the Convertible 12% Promissory Note Warrants upon issuance but may receive proceeds upon their exercise.
Zero Coupon Convertible Promissory Note
On May 7, 2024, the Company entered into a zero coupon convertible promissory note agreement for $0.6 million with a one year term, issued at $0.1 million discount. The lender retains the option to convert any or all outstanding and unpaid principal amount and interest into shares of the Company's common stock from the date of issuance until the maturity date. Concurrently with this agreement, the Company issued the lender 416,667 shares of common stock as well as warrants that allow the lender to acquire up to 550,000 shares of common stock at an initial exercise price of $2.00 per share, subject to adjustment. Pursuant to the agreement, the Company may issue up to three additional zero coupon convertible promissory notes in the aggregate principal amount of $1.8 million.
Convertible Promissory Notes
On May 9, 2024, the Company entered into a convertible promissory note agreement for $0.4 million with a one year term, issued at $0.1 million discount. The lender retains the option to convert any or all outstanding and unpaid principal amount and interest into shares of the Company's common stock from the date of issuance until the maturity date. Concurrently with this agreement, the Company issued the lender 250,000 shares of common stock as well as warrants that allow the lender to acquire up to 330,000 shares of common stock at an initial exercise price of $2.00 per share, subject to adjustment. Pursuant to the agreement, the Company may issue up to three additional convertible promissory notes in the aggregate principal amount of $1.1 million. In connection with the three additional tranches, the Company may issue an aggregate of up to 750,000 additional shares of common stock and issue warrants that entitle holders to an aggregate of up to 990,000 shares of common stock at the lender’s sole discretion. Each additional promissory note will have identical terms as the original note, and each additional common stock purchase warrant will have identical terms as the original warrant.
Cash Flows
The following is a summary of our cash flows (in thousands):
| | | | | | | | | | | |
| For the Three Months Ended March 31, |
| 2024 | | 2023 |
Net cash used in operating activities | $ | (4,034) | | | $ | (4,914) | |
Net cash provided by (used in) investing activities | $ | 35 | | | $ | (13) | |
Net cash provided by financing activities | $ | 4,007 | | | $ | 5,558 | |
Net cash used in operating activities
Net cash used in operating activities decreased by $0.9 million for the three months ended March 31, 2024 as compared to the three months ended March 31, 2023 was primarily attributable to the use of current liabilities that increased the accounts payable and accrued expenses in lieu of cash.
Net cash used in operating activities of $4.0 million for the three months ended March 31, 2024 comprises primarily of NKGen’s net loss of $5.4 million and of non-cash charges of $0.9 million partially offset by $2.3 million in changes related to our operating assets and liabilities. The changes in our operating assets and liabilities comprise primarily of a $1.9 million change in the accounts payable and accrued expenses.
Net cash used in operating activities of $4.9 million for the three months ended March 31, 2023 comprises primarily of NKGen’s net loss of $8.3 million partially offset by $1.7 million in non-cash charges. The non-cash charges are primarily comprised of a $1.5 million change in fair value of Legacy Convertible Notes due to related parties and $1.3 million of stock-based compensation.
Net cash provided by (used in) investing activities
Net cash provided by (used in) investing activities increased by less than $0.1 million for the three months ended March 31, 2024 as compared to the three months ended March 31, 2023. The increase was primarily attributable to the sale of property and equipment.
Net cash provided by investing activities was less than $0.1 million for three months ended March 31, 2024, which consisted of sales of property and equipment.
Net cash used in investing activities was less than $0.1 million for the three months ended March 31, 2023, which consisted of purchases of capitalized software.
Net cash provided by financing activities
Net cash provided by financing activities decreased by $1.6 million for the three months ended March 31, 2024 as compared to the three months ended March 31, 2023. The decrease was primarily due to proceeds from related party loans in 2023, offset by the proceeds received from the amendment to the FPA agreements and issuance of Convertible 12% Promissory Notes, Convertible Bridge Loans, and Bridge Loans in 2024.
Net cash provided by financing activities was $4.0 million for the three months ended March 31, 2024, which primarily consisted of $1.8 million from the amendment to the FPA agreements, $0.7 million from the issuance of the Convertible Bridge Loans, $0.6 million from the issuance of Convertible 12% Promissory Notes, $0.5 million from repayments of receivables from shareholder, $0.3 million from the amendment to the PIPE Warrants, and $0.2 million from the issuance of bridge loans offset by less than $0.1 million in payments of transaction costs.
Net cash provided by financing activities was $5.6 million for the three months ended March 31, 2023, which primarily consisted of proceeds of $4.5 million from Related Party Loan and $1.1 million from issuance of Legacy Convertible Notes, partially offset by less than $0.1 million in repayments on payroll protection program loans.
Contractual Obligations and Commitments
Leases
Our operating leases primarily consist of corporate offices. For additional information, see Note 14, Commitments and Contingencies, in the notes to the unaudited condensed consolidated financial statements included in Item 1, “Financial Statements" of this Quarterly Report on Form 10-Q.
Long-Term Debt
We have long-term debt which matures in 2027. For additional information, see Note 6, Convertible Notes, and Note 7, Debt, in the notes to the unaudited condensed consolidated financial statements included in Item 1, “Financial Statements,” of this Quarterly Report on Form 10-Q.
Critical Accounting Policies and Estimates
Our management’s discussion and analysis of our financial condition and results of operations is based on our financial statements, which have been prepared in accordance with generally accepted accounting principles in the United States, or GAAP. The preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported revenues and expenses during the reporting periods. We evaluate these estimates and judgments on an ongoing basis. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Our actual results may differ from these estimates under different assumptions or conditions.
While our significant accounting policies are more fully described in Note 2, Summary of Significant Accounting Policies, to our financial statements, we believe that the following accounting policies are the most critical to fully understanding and evaluating our financial condition and results of operations.
Accrued Clinical and Research and Development Expenses
All research and development costs are expensed in the period incurred. Research and development expenses primarily consist of services provided by contract organizations for clinical development, salaries, and related expenses for personnel, including stock-based compensation expense, outside service providers, facilities costs, fees paid to consultants and other professional services, license fees, depreciation and supplies used in research and development. Payments made prior to the receipt of goods or services to be used in research and development are capitalized until the related goods or services are received.
As part of the process of preparing our financial statements, we are required to estimate our accrued expenses as of each balance sheet date. This process involves reviewing open contracts and purchase orders, communicating with our personnel to identify services that have been performed on our behalf and estimating the level of service performed and the associated cost incurred for the service when we have not yet been invoiced or otherwise notified of the actual cost. We make estimates of our accrued expenses as of each balance sheet date based on facts and circumstances known to us at that time. We periodically confirm the accuracy of our estimates with the service providers and make adjustments, if necessary. The significant estimates in our accrued clinical trial and research and development expenses include the costs incurred for services performed by our vendors in connection with clinical trial and research and development activities for which we have not yet been invoiced.
We determine our expenses related to clinical trial and research and development activities on our estimates of the services received and efforts expended pursuant to quotes and contracts with vendors that conduct clinical trials and research and development on our behalf. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows. There may be instances in which payments made to our vendors will exceed the level of services provided and result in a prepayment of the clinical trial and research and development expense. In accruing service fees, we estimate the time period over which services will be performed and the level of effort to be expended in each period. If the actual timing of the performance of services or the level of effort varies from our estimate, we adjust the accrual or prepaid expense accordingly. Advance payments for goods and services that will be used in future clinical trial or research and development activities are expensed when the activity has been performed or when the goods have been received rather than when the payment is made.
Although we do not expect our estimates to be materially different from amounts actually incurred, if our estimates of the status and timing of services performed differ from the actual status and timing of services performed, it could result in our reporting amounts that are too high or too low in any particular period. To date, there have been no material differences between our estimates of such expenses and the amounts actually incurred.
Stock-Based Compensation
Stock-based compensation expense is comprised of stock options awarded to employees and consultants. Our stock option awards granted to date contain service based vesting conditions only and do not require the achievement of a market or performance condition in order to vest. These share-based awards are accounted for under the fair-value-based method prescribed by ASC 718-10, Stock Compensation. The fair value of stock options is estimated using the Black-Scholes option pricing model on the date of grant. This option pricing model involves a number of estimates, including the per share value of the underlying common stock, exercise price, estimate of future volatility, expected term of the stock option award, risk-free interest rate and expected annual dividend yield.
We recognize the expense for options with graded-vesting schedules on a straight-line basis over the requisite service period, which is generally the vesting period. Forfeitures are recognized as they occur.
Valuation of Common Shares
Given the absence of a public trading market for our common shares prior to October 2, 2023, which was the first day of trading of our common stock following the Closing, and in accordance with the American Institute of Certified Public Accountants Accounting and Valuation Guide, Valuation of Privately- Held-Company Equity Securities Issued as Compensation, our board of directors exercises its reasonable judgment and considered numerous objective and subjective factors to determine the best estimate of fair value of our common shares, including, but not limited to:
•independent third-party valuations of our common shares;
•capital resources and financial condition;
•the likelihood and timing of achieving a liquidity event;
•historical operating and financial performance as well as our estimates of future financial performance;
•valuations of comparable companies;
•the status of our development;
•the relative lack of marketability of our common shares prior to the October 2, 2023;
•industry information such as market growth and volume and macro-economic events;
•additional objective and subjective factors relating to our business; and
•implied fair values upon a merger transaction.
Prior to October 2, 2023, our board of directors determined the fair value of our common shares using both the income and market approach valuation methods. The income approach estimates value based on the expectation of future cash flows that a company will generate. The market approach estimates value based on a comparison of the subject company to comparable public companies in a similar line of business as well as implied fair values upon a merger transaction such as the Business Combination. Under the market approach, based on a comparison of the subject company to comparable public companies in a similar line of business, a discount for lack of marketability (“DLOM”) was applied to arrive at a fair value of common shares. A DLOM was meant to account for the lack of marketability of shares that were not publicly traded. The valuation of common shares underlying common stock options granted during the year ended December 31, 2023 were estimated under the market approach, based upon the implied fair value of common stock agreed upon in the Business Combination, where the fair values of our common shares as of the respective grant dates were determined using a linear interpolation between the previous valuation and the anticipated closing date of the Business Combination based on circumstances existing as of the respective grant dates. It was determined that the straight-line calculation provides the most reasonable basis for the valuation of our common stock because there was no single event that occurred during the period between the valuation dates that would have caused a material change in fair value.
Applying these valuation approaches involves the use of estimates, judgments and assumptions that are highly complex and subjective, including our expected future revenue and expenses, the determination of discount rates, interpolations, valuation multiples, the selection of comparable public companies and the probability of future events. Changes in any or all of these estimates and assumptions impact our valuation as of each valuation date. Such changes may have a material impact on the valuation of our common shares and our share-based awards.
Beginning October 2, 2023, the fair value of our common shares was based upon our publicly listed share price.
Accounting for Select Financial Instruments
In connection with and following the Business Combination, among other instruments, we issued Public Warrants, Private Warrants, PIPE Warrants, SPA Warrants, Working Capital Warrants, Convertible Bridge Loan Warrants, Convertible 12% Promissory Note Warrants, Convertible 12% Promissory Notes, Senior Convertible Notes, Deferred Founder Shares, and a forward purchase derivative (collectively, “Select Financial Instruments”). The accounting determinations surrounding the Select Financial Instruments has a significant effect on our reported financial position and results of operations.
We determine the accounting classification of the Select Financial Instruments by first assessing each instrument under Financial Accounting Standards Board (“FASB”) Accounting Standard Codification (“ASC”) 480, Distinguishing Liabilities from Equity, then assessing each instrument under ASC 815, Derivatives and Hedging Activities. Under ASC 480, instruments are considered liability classified if they are mandatorily redeemable, obligate us to settle the warrants or the underlying shares by paying cash or other assets, and instruments that must or may require settlement by issuing variable number of shares. If instruments do not meet the liability classification under ASC 480-10, we assess the requirements under ASC 815-40, which states that contracts that require or may require the issuer to settle the contract for cash are liabilities recorded at fair value, irrespective of the likelihood of the transaction occurring that triggers the net cash settlement feature. If the financial instruments do not require liability classification under ASC 815-40, in order to conclude equity classification, we also assess whether the instruments are indexed to our own common stock and whether the instruments are classified as equity under ASC 815-40 or other GAAP. After all such assessments, we conclude whether the instruments are classified as liability or equity.
In addition, ASC 815 requires companies to bifurcate certain features from their host instruments and account for them as free-standing derivative financial instruments should certain criteria be met. We evaluate our financial instruments to determine whether such instruments are derivatives or contain features that qualify as embedded derivatives. Embedded derivatives must be separately measured from the host contract if all the requirements for bifurcation are met. The assessment of the conditions surrounding the bifurcation of embedded derivatives depends on the nature of the host contract and the features of the derivatives. Bifurcated embedded derivatives are recognized at fair value, with changes in fair value recognized in the unaudited condensed consolidated statements of operations and comprehensive loss each period. Bifurcated embedded derivatives are classified with the related host contract in our unaudited condensed consolidated balance sheets. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is re-assessed at the end of each reporting period.
For convertible debt instruments that are not considered liabilities under ASC 480 or ASC 815, we apply ASC 470, Debt, for the accounting of such instruments, including any premiums or discounts.
Liability classified instruments require fair value accounting at issuance and subsequent to initial issuance with all changes in fair value after the issuance date recorded in the unaudited condensed consolidated statements of operations and comprehensive loss. Equity classified instruments only require fair value accounting at issuance with no changes recognized subsequent to the issuance date.
Based upon the application of the foregoing accounting guidance to the terms, features, and circumstances surrounding the Company’s Select Financial Instruments, the Public Warrants, SPA Warrants, and Deferred Founder Shares were determined to be equity classified instruments, and the Senior Convertible Notes, Private Warrants, PIPE Warrants, Working Capital Warrants, Legacy Convertible Notes, Convertible Bridge Loan Warrants, Convertible 12% Promissory Note Warrants, Convertible 12% Promissory Notes, and forward purchase derivative were determined to be liability classified instruments. While the Senior Convertible Notes were determined to be liability-classified, they were determined to be in-scope of ASC 470 and not in-scope of ASC 480 or ASC 815. Accordingly, Senior Convertible Notes will not be measured at fair value on a recurring basis as the fair value measurement of this instrument was for purposes of the relative fair value allocation described below as the Senior Convertible Notes were issued together with the SPA Warrants.
Fair Value of Financial Instruments
We account for the fair value of our financial instruments under the framework established by US GAAP which defines fair value and expands disclosures about fair value measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The standard describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value. These estimates may be subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision.
Level 1 — Quoted prices in active markets for identical assets or liabilities we have the ability to access at the measurement date.
Level 2 — Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of assets or liabilities.
Level 3 — Pricing inputs that are unobservable, supported by little or no market activity and are significant to the fair value of the assets or liabilities.
Transfers to/from Levels 1, 2, and 3 are recognized at the beginning of the reporting period. There were no transfers to/from Levels 1, 2, and 3 during the three months ended March 31, 2024 and 2023.
ASC 820, Fair Value Measurement, states that in many cases, the transaction price will equal the fair value (for example, that might be the case when on the transaction date the transaction to buy an asset takes place in the market in which the asset would be sold). In determining whether a transaction price represents the fair value at initial recognition, we consider various factors such as whether the transaction was between related parties, is a forced transaction, or whether the unit of account for the transaction price does not represent the unit of account for the measured instrument.
We do not measure assets at fair value on a recurring basis. The Company's liabilities that are measured at fair value on a recurring basis are its liability classified warrants, Convertible 12% Promissory Notes, and forward purchase derivative liabilities. Refer to Note 9, Fair Value of Financial Instruments, for further discussion regarding the Company’s fair value measurements. The carrying value of our related party loans approximates fair value as the stated interest rate approximates market rates for similar loans and due to the short-term nature of such loans, which are due within three years or less from issuance. The carrying value of our cash, restricted cash, accounts payable, accrued expenses, other current liabilities, prepaid expenses and other current assets, capitalized software, related party loans, and revolving line of credit approximates fair value primarily due to the short-term nature of such accounts.
The fair value of equity-classified instruments are determined based on trading prices of identical securities as of the measurement date. Liability-classified instruments measured at fair value on a recurring basis include the Private Warrants, Working Capital Warrants, forward purchase derivative liabilities, PIPE Warrants, Convertible Bridge Loans, Convertible 12% Promissory Note Warrants, Convertible 12% Promissory Notes and the Legacy Convertible Notes. Determining the fair value of the liability classified instruments requires the use of accounting estimates and assumptions. Liability-classified instruments measured at fair value on a non-recurring basis include the Senior Convertible Notes.
These estimates and assumptions are judgmental in nature and could have a significant effect on our reported financial position and results of operations.
The fair value of the Private Warrants, Working Capital Warrants, Convertible Bridge Loan Warrants, and Convertible 12% Promissory Note Warrants were measured using a Black-Scholes model. The estimated fair value of the liability classified warrants was determined using Level 3 inputs. Inherent in a Black-Scholes model are assumptions related to expected stock-price volatility, expected life, risk-free interest rate and dividend yield. The Company estimates the volatility of its liability classified warrants based on implied volatility from the Company’s traded warrants and from historical volatility of select peer company’s common stock that matches the expected remaining life of each class of warrants. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a maturity similar to the expected remaining life of each class of warrants. The expected life of each class of warrants is assumed to be equivalent to their remaining contractual term. The dividend rate is based on the historical rate, which the Company anticipates remaining at zero.
The fair value of the forward purchase derivative liabilities and PIPE Warrants were estimated using a Monte Carlo simulation approach. Our common share price was simulated with daily time steps for a range of various possible scenarios. The breadth of all possible scenarios was captured in an estimate of volatility, based on comparable companies’ historical equity volatilities, considering differences in their capital structure. The simulated prices were compared against the features of the Forward Purchase Agreements and the PIPE Warrants, including the settlement adjustment and downside protection features. The average value for the forward purchase derivative liabilities and the PIPE warrants across the range of possible scenarios for the respective instrument, discounted to present using the risk-free rate, was used as the fair value of the liabilities.
The fair value of the Convertible 12% Promissory Notes was valued using level three inputs and was estimated using a binomial lattice model. This model generates two probable outcomes of stock price at each point in time or "node", starting from the valuation date until the maturity date. This lattice generates a distribution of stock price. Based on the stock price at each corresponding node, the value of the Notes was determined by evaluating the optimal decision that a holder and/or the issuer would make to maximize its payoff. At maturity, the value of the notes was calculated as the maximum between the principal amount and the conversion value. At each node prior to maturity, the lattice model determines whether the notes would be (i) converted by the holder, or (ii) held by the holder, based on the payoff related to each decision. Volatility in the model was estimated from historical equity volatility, median asset volatility of comparable companies, and was adjusted using our capital structure. The cost of debt used in discounting the notes was estimated based on (i) market yield curve corresponding to our estimated synthetic credit rating, and (ii) observed market spreads of publicly traded comparable debt with similar credit rating and industry.
The Convertible Bridge Loans were issued together with the Convertible Bridge Loan Warrants. The Convertible Bridge Loan Warrants were recorded at fair value, with the residual amount of the proceeds allocated to the convertible debt instrument. The fair value of the Convertible Bridge Loan Warrants was treated as a discount to the Convertible Bridge Loans, which will be amortized to interest expense over the term of the Convertible Bridge Loans.
The Senior Convertible Notes were issued together with the SPA Warrants. Each instrument was recorded at its fair value, limited to a relative fair value based upon the percentage of its fair value to the total fair value based on the transaction price at Closing on September 29, 2023. The relative fair value of the SPA Warrants was treated as a discount to the Senior Convertible Notes, which will be amortized to interest expense over the term of the Senior Convertible Notes.
We determined the stand-alone fair value of the Senior Convertible Notes using a binomial lattice model, which generates a distribution of stock prices over the term of the note, calculates the associated payoff for the note, and discounts the probability-weighted values from the lattice back to the valuation date. The fair value was estimated by using assumptions that market participants would use in pricing a convertible debt instrument, including market interest rates, credit rating, yield curves, and volatilities.
Recently Issued and Adopted Accounting Pronouncements
We describe the recently issued accounting pronouncements that apply in Note 2, Summary of Significant Accounting Policies, of the unaudited condensed consolidated financial statements as of and for the three months ended March 31, 2024.
Emerging Growth Company Status
We qualify as an emerging growth company, as defined in the Jumpstart Our Business Startups (“JOBS Act”) and may remain an emerging growth company for up to five years following the completion of Graf’s initial public offering. For so long as we remain an emerging growth company, we are permitted and intends to rely on certain exemptions from various public company reporting requirements, including delaying adopting new or revised accounting standards issued until such time as those standards apply to private companies, not being required to have our internal control over financial reporting audited by our independent registered public accounting firm pursuant to Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a non-binding advisory vote on executive compensation and any golden parachute payments not previously approved. Accordingly, the information contained herein may be different than the information you receive from other public companies in which you hold stock.
Following the closing of the Business Combination, we are an emerging growth company until the earliest of (i) the last day of the fiscal year following the fifth anniversary of the consummation of Graf’s initial public offering, (ii) the last day of the fiscal year in which we have total annual gross revenue of at least $1.235 billion, (iii) the last day of the fiscal year in which we are deemed to be a “large accelerated filer” as defined in Rule 12b-2 under the Exchange Act, which would occur if the market value of our common stock held by non-affiliates exceeded $700.0 million as of the last business day of the second fiscal quarter of such year, or (iv) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the prior three-year period.
We qualify as a “smaller reporting company,” as such term is defined in Rule 12b-2 of the Exchange Act, meaning that the market value of our common stock held by non-affiliates plus the proposed aggregate amount of gross proceeds to the Company as a result of the Business Combination is less than $700.0 million and our annual revenue is less than $100.0 million during the most recently completed fiscal year. We may continue to be a smaller reporting company following the closing of the Business Combination if either (i) the market value of our common stock held by non-affiliates is less than $250.0 million or (ii) our annual revenue is less than $100.0 million during the most recently completed fiscal year and the market value of our common stock held by non-affiliates is less than $700.0 million. If we are a smaller reporting company at the time we cease to be an emerging growth company, we may continue to rely on exemptions from certain disclosure requirements that are available to smaller reporting companies. Specifically, as a smaller reporting company, we may choose to present only the two most recent fiscal years of audited financial statements in our Annual Report on Form 10-K and, similar to emerging growth companies, smaller reporting companies have reduced disclosure obligations regarding executive compensation.
Item 3. Quantitative and Qualitative Disclosures about Market Risk.
We are a smaller reporting company as defined by Rule 12b-2 of the Securities Exchange Act of 1934 and are not required to provide the information under this item.
Item 4. Controls and Procedures.
Evaluation of Disclosure Controls and Procedures.
We maintain “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act, that are designed to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is (1) recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms and (2) accumulated and communicated to our management, including our principal executive officer and principal financial officer, to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.
Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2024. Based upon the evaluation, our principal executive officer and principal financial officer concluded that, as of such date, our disclosure controls and procedures were effective and were operating at a reasonable assurance level.
Changes in Internal Control over Financial Reporting.
There were no changes in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the period covered by this Quarterly Report on Form 10-Q that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
PART II. OTHER INFORMATION
Item 1. Legal Proceedings.
From time to time, we may be involved in various legal proceedings relating to claims arising from the ordinary course of business. Our management believes that there are currently no claims or actions pending against us, the ultimate disposition of which could have a material adverse effect on our results of operations, financial condition or cash flows.
Item 1A. Risk Factors.
In addition to the other information set forth in this report, you should carefully consider the risk factors disclosed in Item 1A. “Risk Factors,” of our Annual Report on Form 10-K for the year ended December 31, 2023.

- DefinitionThe number of securities classified as temporary equity that have been issued and are held by the entity's shareholders. Securities outstanding equals securities issued minus securities held in treasury. Temporary equity is a security with redemption features that are outside the control of the issuer, is not classified as an asset or liability in conformity with GAAP, and is not mandatorily redeemable. Includes any type of security that is redeemable at a fixed or determinable price or on a fixed or determinable date or dates, is redeemable at the option of the holder, or has conditions for redemption which are not solely within the control of the issuer. If convertible, the issuer does not control the actions or events necessary to issue the maximum number of shares that could be required to be delivered under the conversion option if the holder exercises the option to convert the stock to another class of equity. If the security is a warrant or a rights issue, the warrant or rights issue is considered to be temporary equity if the issuer cannot demonstrate that it would be able to deliver upon the exercise of the option by the holder in all cases. Includes stock with put option held by ESOP and stock redeemable by holder only in the event of a change in control of the issuer.

Company Information |
Company Information NKGen Biotech, Inc. (“Company” or “NKGen”), a Delaware corporation headquartered in Santa Ana, California, is a clinical-stage biotechnology company focused on the development and commercialization of innovative autologous, allogeneic and CAR-NK natural killer cell therapies utilizing their proprietary SNK (Super-Natural-Killer) platform. The Company was formerly majority owned and controlled by NKMAX Co., Ltd. (“NKMAX”), a company formed under the laws of the Republic of Korea. The Company was originally incorporated in Delaware on January 28, 2021 under the name Graf Acquisition Corp. IV (“Graf”), as a special-purpose acquisition company for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or engaging in any other similar business combination with one or more businesses or entities. On April 14, 2023, the Company entered into the Agreement and Plan of Merger by and among Graf, Austria Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of Graf (“Merger Sub”), and NKGen Biotech, Inc. (“Merger Agreement”). Upon consummation of the transactions under the Merger Agreement on September 29, 2023 (the “Business Combination”), Merger Sub merged with and into NKGen Biotech, Inc. (“Legacy NKGen”) with Legacy NKGen surviving the merger as a wholly owned subsidiary of Graf (the “Merger”). In connection with the consummation of the Business Combination (the “Closing”), Graf was renamed to “NKGen Biotech, Inc.” and Legacy NKGen changed its name to “NKGen Operating Biotech, Inc.” The common stock and warrants of the combined company began trading on The Nasdaq Stock Market LLC under the symbols “NKGN” and “NKGNW”, respectively, on October 2, 2023. Throughout the notes to the unaudited condensed consolidated financial statements, unless otherwise noted or otherwise suggested by context, the “Company” refers to Legacy NKGen prior to the consummation of the Business Combination, and the Company after the consummation of the Business Combination. Liquidity The Company follows Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 205-40, Presentation of Financial Statements — Going Concern, which requires that management evaluate whether there are relevant conditions and events that in aggregate raise substantial doubt about the entity’s ability to continue as a going concern and to meet its obligations as they become due within one year after the date that the unaudited condensed consolidated financial statements are issued. Under the guidance, the Company must first evaluate whether there are conditions and events that raise substantial doubt about the entity’s ability to continue as a going concern (step 1). If the Company concludes substantial doubt is raised, management also is required to consider whether its plans alleviate that doubt (step 2). The Company has a limited operating history, has incurred significant operating losses since its inception, and the revenue and income potential of the Company’s business and market are unproven. The Company’s unaudited condensed consolidated financial statements are prepared using the generally accepted accounting principles applicable to a going concern, which contemplates the realization of assets and liquidation of liabilities in the normal course of business. As of March 31, 2024, the Company had an accumulated deficit of $167.5 million and cash and cash equivalents of less than $0.1 million. To date, the Company has funded its operations primarily with the net proceeds from the issuance of senior convertible promissory notes, the issuance of related party loans, the issuance of bridge loans, the issuance of convertible bridge loans, the issuance of convertible 12% promissory notes, draws upon a revolving line of credit, the issuance and sale of equity securities, PIPE warrants, private placements, the amendment of private placements, and proceeds from the Business Combination. The Company expects to incur substantial operating losses for the next several years and will need to obtain additional near-term financing in order to continue its research and development activities, initiate and complete clinical trials and launch and commercialize any product candidates for which it receives regulatory approval. Management has prepared cash flow forecasts which indicate that based on the Company’s expected operating losses and negative cash flows, there is substantial doubt about the Company’s ability to continue as a going concern for twelve months from the issuance of these unaudited condensed consolidated financial statements. The Company plans to continue to fund its losses from operations and capital funding needs through additional debt or equity financings to be received from related parties, private equity, or other sources. If the Company is not able to secure adequate additional funding, the Company may be forced to make reductions in spending, extend payment terms with suppliers, liquidate assets where possible, suspend or curtail planned programs, or may be forced to cease operations or file for bankruptcy protection. Any of these actions could materially harm the Company’s business, results of operations and future prospects. There can be no assurance that such financing will be available or will be at terms acceptable to the Company. The preparation of these unaudited condensed consolidated financial statements does not include any adjustments that may result from the outcome of this uncertainty.

Summary of Significant Accounting Policies |
Summary of Significant Accounting Policies Basis of Presentation NKMAX held a majority of the voting power of Legacy NKGen before the Business Combination and continued to hold a majority of the voting power of the Company after the Business Combination. Therefore, as there was no change in control, the Business Combination was accounted for as a common control transaction with respect to Legacy NKGen along with a reverse recapitalization of the Company. Accordingly, for accounting purposes, the financial statements of the Company represent a continuation of the financial statements of Legacy NKGen with the Business Combination being treated as the equivalent of Legacy NKGen issuing shares for the net assets of Graf, accompanied by a recapitalization. The net assets of Graf were recognized as of the Closing at historical cost, with no goodwill or other intangible assets recorded. Operations prior to the Business Combination are presented as those of Legacy NKGen and the accumulated deficit of Legacy NKGen has been carried forward after Closing. Upon the consummation of the Business Combination, all of Legacy NKGen’s equity was converted into equity of the Company based upon an exchange ratio (“Exchange Ratio”). In addition, all stock options of Legacy NKGen were converted using the Exchange Ratio into options exercisable for shares of the Company with the same terms and vesting conditions. The Exchange Ratio as of September 29, 2023, the date of Closing, was approximately 0.408. All periods prior to the Business Combination have been retrospectively adjusted using the Exchange Ratio to reflect the reverse recapitalization. In connection with the reverse recapitalization treatment of the Business Combination, all issued and outstanding securities of Graf upon Closing were treated as issuances of the Company upon the consummation of the Business Combination. The accompanying financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) and generally accepted accounting principles in the United States of America (“US GAAP”). The Company maintains its accounting records under the accrual method of accounting in conformity with US GAAP. The condensed consolidated balance sheet as of December 31, 2023 included herein was derived from the audited financial statements as of that date. Certain information and disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such regulations. Accordingly, these unaudited condensed consolidated financial statements and accompanying footnotes should be read in conjunction with NKGen’s financial statements as of and for the year ended December 31, 2023. The results for the interim periods are not necessarily indicative of results for the full year. In the opinion of management, all adjustments, of a normal recurring nature, considered necessary for a fair presentation have been included in the unaudited condensed consolidated financial statements. The Company believes that the disclosures provided herein are adequate to prevent the information presented from being misleading. Principles of Consolidation The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiary. All significant intercompany balances and transactions have been eliminated in consolidation. Use of Estimates The preparation of unaudited condensed consolidated financial statements in accordance with US GAAP requires management to make estimates and assumptions that impact the reported amounts of certain assets and liabilities, certain disclosures at the date of the unaudited condensed consolidated financial statements, as well as the reported amounts of revenues and expenses during the reporting period. The most significant estimates in the Company’s unaudited condensed consolidated financial statements include, but are not limited to, accrued clinical and research and development expenses, legacy convertible notes, convertible 12% promissory notes, senior convertible promissory notes due to related parties, forward purchase derivative liabilities, derivative warrant liabilities, derivative warrant assets, common stock, and equity awards. These estimates and assumptions are based upon historical experience, knowledge of current events, and various other factors believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the recording of expenses that are not readily apparent from other sources. Actual results could differ materially from those estimates. Restricted Cash Restricted cash consists of funds that are contractually restricted due to a revolving line of credit, which was entered into during June 2023. In accordance with the terms of the revolving line of credit, the Company was required to maintain $15.0 million in cash balances with the lender from March 31, 2024 until repayment of all principals and other payables to the lender under the revolving line of credit was made as additional collateral for the borrowings. In April 2024, the lender subsequently waived the minimum cash deposit requirement in exchange for the Company's agreement to use the lender as their primary banking relationship. As of both March 31, 2024 and December 31, 2023, $0.3 million in restricted cash was recorded on the unaudited condensed consolidated balance sheet. The Company includes its restricted bank deposits in cash, cash equivalents and restricted cash when reconciling beginning-of-period and end-of-period total amounts shown on the unaudited condensed consolidated statements of cash flows for the three months ended March 31, 2024. Deferred Debt Issuance Costs Costs incurred through the issuance of the revolving line of credit to parties who are providing short-term financing availability are reflected as deferred debt issuance costs. These costs are generally amortized to interest expense over the life of the financing instrument using the effective interest rate method or other methods approximating the effective interest method. As of both March 31, 2024 and December 31, 2023, less than $0.1 million in deferred debt issuance costs were recorded to prepaid expenses and other current assets on the unaudited condensed consolidated balance sheets. Hybrid Instruments The Company follows Financial Accounting Standards Board (“FASB”) Accounting Standard Codification (“ASC”) 480, Distinguishing Liabilities from Equity, when evaluating the accounting for its hybrid instruments. A financial instrument that embodies an unconditional obligation, or a financial instrument other than an outstanding share that embodies a conditional obligation, that the issuer must or may settle by issuing a variable number of its equity shares shall be classified as a liability (or an asset in some circumstances) if, at inception, the monetary value of the obligation is based solely or predominantly on any one of the following: (a) a fixed monetary amount known at inception; (b) variations in something other than the fair value of the issuer’s equity shares; or (c) variations inversely related to changes in the fair value of the issuer’s equity shares. Hybrid instruments meeting these criteria are not further evaluated for any embedded derivatives and are carried as a liability at fair value at each balance sheet date. Derivative Instruments FASB ASC 815, Derivatives and Hedging Activities, requires companies to bifurcate certain features from their host instruments and account for them as free-standing derivative financial instruments should certain criteria be met. The Company does not use derivative instruments to hedge exposures to interest rate, market, or foreign currency risks. The Company evaluates its financial instruments to determine whether such instruments are derivatives or contain features that qualify as embedded derivatives. Embedded derivatives must be separately measured from the host contract if all the requirements for bifurcation are met. The assessment of the conditions surrounding the bifurcation of embedded derivatives depends on the nature of the host contract and the features of the derivatives. Bifurcated embedded derivatives are recognized at fair value, with changes in fair value recognized in the unaudited condensed consolidated statements of operations and comprehensive loss each period. Bifurcated embedded derivatives are classified with the related host contract in the Company’s unaudited condensed consolidated balance sheets. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is re-assessed at the end of each reporting period. Debt For convertible debt instruments that are not considered liabilities under ASC 480 or ASC 815, the Company applies ASC 470, Debt, for the accounting of such instruments, including any premiums or discounts. The Company’s bridge loans, senior convertible promissory notes, and convertible bridge loans accounted for under ASC 470. Accrued interest paid-in-kind is added to the carrying amount of the Company’s senior convertible promissory notes. Subscription and Shareholder Receivables The Company records stock issuances at the effective date. If the amounts are not funded upon issuance, the Company records a subscription receivable or shareholder receivable as an asset on the balance sheet. When subscription receivables or shareholder receivables are not received prior to the balance sheet date in satisfaction of the requirements under ASC 505, Equity, the subscription or shareholder receivable is reclassified as a contra account to stockholder’s equity (deficit) on the balance sheet. Shareholder receivables represent amounts due from shareholders. If the shareholder does not fund the receivable prior to the balance sheet date, the Company records a receivable that is reclassified as a contra account to stockholder’s deficit on the balance sheet. During March 31, 2024, $0.5 million due from shareholders was received by the Company. Impairment of Long-Lived Assets The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate the carrying amount of an asset, or asset group, may not be recoverable. Recoverability is measured by a comparison of the carrying amount of an asset or asset group to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset or asset group exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset or asset group exceeds the fair value of the asset or asset group. The Company has not recognized any impairment losses for the three months ended March 31, 2024 and 2023. Fair Value Option In lieu of bifurcation, on an instrument-by-instrument basis, the Company may elect the fair value option for certain financial instruments that meet the required criteria under ASC 825, Financial Instruments. The Company elected the fair value option for both its legacy convertible notes and convertible 12% promissory notes, which met the required criteria under ASC 825, Financial Instruments. Interest expense associated with both the legacy convertible and convertible 12% promissory notes is included in the change in fair value of such instruments. Fair Value of Financial Instruments The Company accounts for the fair value of its financial instruments under the framework established by US GAAP which defines fair value and expands disclosures about fair value measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The standard describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value. These estimates may be subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Level 1 — Quoted prices in active markets for identical assets or liabilities the Company has the ability to access at the measurement date. Level 2 — Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of assets or liabilities. Level 3 — Pricing inputs that are unobservable, supported by little or no market activity and are significant to the fair value of the assets or liabilities. Transfers to/from Levels 1, 2, and 3 are recognized at the beginning of the reporting period. There were no transfers to/from Levels 1, 2, and 3 during three months ended March 31, 2024 and 2023. ASC 820, Fair Value Measurement, states that in many cases, the transaction price will equal the fair value (for example, that might be the case when on the transaction date, the transaction to buy an asset takes place in the market in which the asset is sold). In determining whether a transaction price represents the fair value at initial recognition, the Company considers various factors such as whether the transaction was between related parties, is a forced transaction, or whether the unit of account for the transaction price does not represent the unit of account for the measured instrument. The Company does not measure assets at fair value on a recurring basis. The Company's liabilities that are measured at fair value on a recurring basis are its liability classified warrants, convertible 12% promissory notes, and forward purchase derivative liabilities. Refer to Note 9, Fair Value of Financial Instruments, for further discussion regarding the Company’s fair value measurements. The carrying value of the Company’s related party loans approximates fair value as the stated interest rate approximates market rates for similar loans and due to the short-term nature of such loans, which are due within three years or less from issuance. The carrying value of the Company’s cash, restricted cash, accounts payable, accrued expenses, bridge loans, convertible bridge loans, other current liabilities, and revolving line of credit approximates fair value primarily due to the short-term nature of such accounts. Leases The Company accounts for its leases under ASC 842, Leases. The operating lease right-of-use (“ROU”) asset represents the Company’s right to use an underlying asset during the lease term, and operating lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating leases are included in the ROU asset, current operating lease liabilities, and non-current operating lease liabilities in the accompanying condensed consolidated balance sheets. The operating lease ROU asset and lease liabilities are initially recognized based on the present value of the future minimum lease payments over the lease term at commencement date calculated using the Company’s incremental borrowing rate applicable to the lease asset, unless the implicit rate is readily determinable. The operating lease ROU asset also includes any lease payments made at or before lease commencement and exclude any lease incentives received. The Company determines the lease term as the noncancelable period of the lease and may include options to extend or terminate the lease when it is reasonably certain the Company will exercise that option. Leases with a term of 12 months or less are not recognized in the balance sheet. The Company’s leases do not contain any residual value guarantees. Lease expense for minimum lease payments is recognized as rent expense on a straight-line basis over the lease term. Operating expenses such as common area maintenance and utilities are treated as variable lease payments. Stock-Based Compensation Stock-based compensation expense is comprised of stock options awarded to employees and consultants. The Company accounts for share-based awards under the fair value method prescribed by ASC 718-10, Stock Compensation. The fair value of stock options is estimated using the Black-Scholes option pricing model on the date of grant. This option pricing model involves a number of estimates, including the per share value of the underlying common stock, exercise price, estimate of future volatility, expected term of the stock option award, risk-free interest rate and expected annual dividend yield. The fair value of the shares of common stock underlying the stock options has historically been determined by the Company’s board of directors as there was no public market for the underlying common stock prior to October 2, 2023. The Company’s board of directors determines the fair value of the Company’s common stock by considering a number of objective and subjective factors including contemporaneous third-party valuations of its common stock, the valuation of comparable companies, sales of the Company’s common stock to outside investors in arms-length transactions, the Company’s operating and financial performance, the lack of marketability, and general and industry specific economic outlook, and the implied fair values upon a merger transaction, amongst other factors. The Company recognizes the expense for options with graded-vesting schedules on a straight-line basis over the requisite service period, which is generally the vesting period. Forfeitures are recognized as they occur. Basic and Diluted Net Loss Per Common Share Basic net loss per common share is computed by dividing net loss for the year by the weighted-average number of common shares outstanding during the year. Diluted net loss per share is computed by dividing the net loss by the weighted-average number of common shares outstanding and potentially dilutive securities outstanding for the period using the treasury stock or if-converted method if their inclusion is dilutive. Diluted net loss per common share is the same as basic net loss per common share because the inclusion of potentially dilutive shares would be anti-dilutive to the calculation of net loss per common share. The Company has one class of shares issued and outstanding. Accordingly, basic and diluted net loss per share is not allocated among multiple classes of shares. Basic and diluted net loss per share for all periods prior to the Closing have been retrospectively adjusted by the Exchange Ratio to affect the reverse recapitalization. Potentially anti-dilutive shares excluded from the calculation of diluted net loss per share for three months ended March 31, 2024 include the following: | | | | | | Private warrants | 4,721,533 | Working capital warrants | 523,140 | Public warrants | 3,432,286 | PIPE warrants | 10,209,994 | Stock options | 1,969,261 | SPA warrants | 1,000,000 | Senior convertible notes’ shares | 1,000,000 | Deferred founder shares (1) | 1,173,631 | Convertible bridge loan warrants | 1,250,000 | Convertible bridge loan consideration shares | 7,334 | Convertible bridge loans | 619,146 | Convertible 12% promissory note warrants | 660,000 | Convertible 12% promissory notes | 367,850 | Total | 26,934,175 |
(1)As described in Note 8, Related Party Transactions, deferred founder shares do not have voting rights, do not participate in dividends and are not transferrable absent the Company’s consent. Therefore, while deferred founder shares are considered outstanding for legal purposes and are included in the total quantity of outstanding shares on the unaudited condensed consolidated statements of stockholders’ deficit, they are not considered outstanding for accounting purposes, including basic and diluted net loss per share purposes. Emerging Growth Company The Company is an “Emerging Growth Company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart our Business Startups Act of 2012, (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s unaudited condensed consolidated financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. Recently Issued Accounting Pronouncements Not Yet Adopted In December 2023, the FASB issued ASU No. 2023-09, Improvements to Income Tax Disclosures (Topic 740). The ASU requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as additional information on income taxes paid. The ASU is effective on a prospective basis for annual periods beginning after December 15, 2024. Early adoption is also permitted for annual financial statements that have not yet been issued or made available for issuance. This ASU will result in the required additional disclosures being included in the Company's unaudited condensed consolidated financial statements, once adopted. The Company is currently evaluating the impact of this standard on its financial statements and related disclosures.

In connection with the Business Combination: •All of Legacy NKGen’s legacy convertible notes were converted into shares of Legacy NKGen common stock immediately prior to Closing and pursuant to their terms, totaling 5,579,266 shares, which were then cancelled and converted into 2,278,598 shares of the Company’s common stock after giving effect to the Exchange Ratio; •All of Legacy NKGen’s 38,185,814 issued and outstanding shares were cancelled and converted into 15,595,262 shares of the Company’s common stock after giving effect to the Exchange Ratio (inclusive of shares attributable to the Legacy NKGen convertible notes); •All of Legacy NKGen’s 5,146,354 issued and outstanding stock options were cancelled and converted into 2,101,760 outstanding stock options of the Company; •The Company’s amended and restated certificate of incorporation and amended and restated bylaws were adopted; •The Company adopted an employee stock purchase plan; and •The Company adopted the 2024 equity incentive plan. The other related events that occurred in connection with the Closing include the following: •The execution of the private placement agreements, as described in Note 4, Private Placement; •The assumption of the public and private warrants, as described in Note 5, Warrants; •The execution of the warrant subscription agreements, as described in Note 5, Warrants; •The conversion of Legacy NKGen’s legacy convertible notes, as described in Note 6, Convertible Notes; •The execution of the securities purchase agreement, as described in Note 6, Convertible Notes; and •The execution of the amended and restated sponsor support and lockup agreement, as described in Note 8, Related Party Transactions. Refer to Note 9, Fair Value of Financial Instruments, for the Company’s measurements with respect to the financial instruments issued in connection with the foregoing agreements. Legacy NKGen incurred $7.5 million of transaction costs in connection with the Business Combination, which was determined to be a capital-raising transaction for Legacy NKGen. Of the $7.5 million in transaction costs, $4.2 million and $3.3 million was allocated on a relative fair value basis to equity-classified instruments and liability-classified instruments, respectively. The following tables reconcile elements of the Business Combination to the Company’s unaudited condensed consolidated financial statements, and should be read in conjunction with the footnotes referenced above (in thousands, except share amounts): | | | | | | | Shares | Graf public shares, net of redemptions | 93,962 | Private placement investors’ shares | 3,683,010 | Graf founder shares | 2,516,744 | Total Graf shares outstanding immediately prior to the Business Combination | 6,293,716 | Conversion of Legacy NKGen convertible promissory notes (after the application of the Exchange Ratio) | 2,278,598 | Legacy NKGen rollover shares (after the application of the Exchange Ratio) | 13,316,662 | Total Legacy NKGen shares | 15,595,260 | Total Company common stock outstanding immediately following the Business Combination | 21,888,976 |

(1)The Graf transaction costs includes a $4.0 million accrual related to a certain vendor to be paid in cash and common stock of $2.0 million each. At Closing, a cash payment of $1.3 million was disbursed to this vendor. The remaining $2.7 million amount was recognized as a component of the unpaid transaction costs assumed from Graf, of which $0.7 million represents a cash settlement obligation, and the remaining $2.0 million represents an obligation to issue a variable number of shares for a fixed monetary amount which was accounted for as a liability under ASC 480, Distinguishing Liabilities from Equity (“ASC 480”). Under ASC 480, the obligation to issue shares is not subsequently measured at fair value with changes recorded in earnings because the monetary amount is fixed. (2)Represents allocated fair value.

Private Placement |
Private Placement Initial Recognition Background Prior to the Closing, the Company entered into private agreements (“Private Placement Agreements”) with investors (“FPA Investors”) consisting of forward purchase agreements (“Forward Purchase Agreements”), subscription agreements, a side letter, and escrow agreements. The Private Placement Agreements closed on September 29, 2023. Pursuant to the Private Placement Agreements, the FPA Investors purchased 3,168,121 shares of common stock (“FPA Shares”) for $32.9 million (“Prepayment Amount”). The Prepayment Amount was deposited into escrow accounts. The terms of the Private Placement Agreements provide that following a one-year period after the Closing, subject to early termination and settlement with respect to any number of FPA Shares at the election of the FPA Investors (“Measurement Period”), funds in the escrow accounts may be released to the FPA Investors, the Company or a combination of both based on a combination of factors, including the volume weighted average price of the Company’s common stock (“VWAP”) over a specified valuation period during the Measurement Period (“Reset Price”), the number of shares sold by the FPA Investors during the Measurement Period, and the application of anti-dilution provisions. The Private Placement Agreements expire at the end of the Measurement Period. All funds in escrow will be released to the Company, the FPA Investors, or a combination of both, at or before the one year anniversary of the Closing. The maximum and minimum that could be released from escrow is the Prepayment Amount and zero, respectively, for both the FPA Investors and the Company. In addition, all interest earned on the funds in the escrow accounts will be released to the FPA Investors. During the Measurement Period, to the extent the Company’s share price approaches or exceeds $10.44 per share, the likelihood and amount of escrow funds to be released to the Company increases and the likelihood and amount of escrow funds to be released to the FPA Investors decreases. Conversely, during the Measurement Period, to the extent the Company’s share price decreases below $10.44 per share, the likelihood and amount of escrow funds to be released to the Company decreases and the likelihood and amount of escrow funds to be released to the FPA Investors increases. Other drivers of settlement outcomes include the number of shares sold by FPA Investors to third parties during the Measurement Period, whereby the selling of shares may decrease portions of escrow funds to be released to the FPA Investors by up to $2.00 per share sold, the application of antidilution provisions, the timing of sales and settlements, among other factors. Additionally, a prepayment shortfall of $0.1 million was established in connection with the Private Placement Agreements (“Prepayment Shortfall”). Pursuant to the terms and conditions of the Private Placement Agreements, sales of FPA Shares to third-parties are required to first be applied towards the Prepayment Shortfall prior to the subscription receivable (described further below). In addition to the FPA Shares, the FPA Investors received 514,889 shares of common stock for no incremental consideration (“Bonus Shares”). The Bonus Shares are not subject to an escrow arrangement. Accounting All FPA Shares and Bonus Shares are outstanding shares of the Company that are not held in escrow, are transferable without restrictions, and have the same voting as well as dividend and liquidation participation rights as other shares of the Company. Accordingly, such shares are equity classified and presented together with other shares of common stock in the unaudited condensed consolidated financial statements. The escrow agreements provide that funds placed into escrow are held in escrow for the benefit of the FPA Investors until they are released to the Company pursuant to the terms of the Private Placement Agreements and the Company’s creditors do not have access to the funds held in escrow in the event of bankruptcy of the Company. Accordingly, the Company accounted for the original Prepayment Amount of $32.9 million as a contra-equity subscription receivable because the funds held in escrow represent receivables from shareholders. The features of the Private Placement Agreements met the derivatives criteria under ASC 815 because they contained an underlying, notional amount, payment provision, and net settlement. Accordingly, a derivative liability was recognized based on the estimated measurement of the portion of the funds in escrow that could be released to the FPA Investors, based on circumstances existing as of Closing. The net balance of the Prepayment Amount presented as a subscription receivable and the derivative liability when considered together represents the estimated amount of escrow funds the Company expects to receive from the escrow accounts. Subsequent changes in fair value of the derivative liability associated with the Private Placement Agreements will be recognized through earnings on a quarterly basis. Upon the Closing, in addition to the $32.9 million subscription receivable, a loss on issuance of forward purchase contract totaling $24.5 million was recorded, which consisted of fair value of the derivative liabilities of $20.2 million plus the fair value of the Bonus Shares of $4.3 million. The forward purchase derivative liabilities are treated as a current liabilities because the Private Placement Agreements mature or otherwise are subject to early termination at or prior to the one year at or before the one year anniversary of the Closing. December 2023 Amendment On December 26, 2023, the Company and an FPA Investor entered into an amendment to their Forward Purchase Agreement ("December 2023 FPA Amendment") for total proceeds of $0.5 million. No other Private Placement agreements were amended during the year ended December 31, 2023. The FPA Amendment provided that, (i) 200,000 FPA Shares were re-designated to Bonus Shares, (ii) the definition of Reset Price was changed (“Amended Reset Price”), (iii) the definition of the prepayment shortfall was amended (“Amended Prepayment Shortfall”), and (iv) the funds in the escrow account were transferred to a separate account held by the FPA Investor. The funds from the FPA Investor in connection with the amendment were not received by the Company until January 2024. The terms of the Amended Reset Price provide for (i) a rolling ceiling effective as of the FPA Amendment execution date based on a weekly trailing VWAP such that the Company does not benefit from increases in share price during the Measurement Period, and (ii) discounts of generally 10.0% to the VWAP measurement that benefit the FPA Investor. Proceeds from the sale of FPA Shares by FPA Investors to third parties are required to be treated as a reduction to the prepayment shortfall until no balance remains in the prepayment shortfall (“Shortfall Sales”), at which point proceeds from such sales of stock may be treated as reductions to the subscription receivable that may result in cash proceeds to the Company. If all FPA Shares are sold without full satisfaction of the prepayment shortfall, the Company is required, at their election, to either pay a cash amount equal to the remaining prepayment shortfall balance or issue additional shares at 90.0% of the VWAP for the trailing 20 trading days. The terms of the Amended Prepayment Shortfall provide for a $0.5 million increase to the FPA Investor’s pre-existing prepayment shortfall of $0.1 million. Upon execution of the FPA Amendment in December 2023, the Company recognized a loss on amendment to forward purchase contract as set forth below (in thousands): | | | | | | | Loss on Amendment | Reduction of subscription receivable | $ | 15,123 | Change in fair value in connection with the amendment of forward purchase contracts | (14,181) | Cash received in connection with the amendments | (500) | Loss on amendment to forward purchase contracts | $ | 442 |
The $0.4 million loss recognized in connection with the FPA Amendment represents the reduction in cash proceeds the Company may receive under the forward purchase contract, partially offset by the reduction in the forward purchase derivative liabilities and the shareholder receivable. As a result of the FPA Amendment, the maximum cash proceeds the Company could receive under the forward purchase contract, reflected in the subscription receivable balance, was lowered. The reduction in the subscription receivable of $15.1 million was caused by (i) the Amended Reset Price, which reduced the maximum price per FPA Share the Company could receive (initially, $10.44 per share), (ii) the re-designation of 200,000 FPA Shares to Bonus Shares, reducing the total quantity of FPA Shares, and (iii) the Amended Prepayment Shortfall, which increased the prepayment shortfall amount. The Company does not receive any consideration for sales or settlements of Bonus Shares or Shortfall Sales, described further below. In addition to the reduction in the subscription receivable, the Company recognized a corresponding reduction in the fair value of the forward purchase derivative liabilities of $14.2 million. January and February 2024 Amendments From January to February 2024, the Company and certain FPA Investors entered into several additional amendments to the Forward Purchase Agreements ("2024 FPA Amendments") for total proceeds to the Company of $1.0 million. The 2024 FPA Amendments provided that, (i) 200,000 additional FPA Shares were re-designated to Bonus Shares, (ii) the definition of the prepayment shortfall consideration was further amended (“2024 Amended Prepayment Shortfall”), and (iii) for the FPA Investor who was not party to the December 2023 FPA Amendment, the definition of Reset Price was changed (“2024 Amended Reset Price”). The terms of the 2024 Amended Reset Price provide the FPA Investor (i) a rolling price per share effective as of the FPA Amendment execution date based on a weekly trailing VWAP, subject to a ceiling of $10.44 per share ("Initial Price"), and (ii) discounts of generally 10.0% to the VWAP measurement that benefit the FPA Investor. The terms of the 2024 Amended Prepayment Shortfall provide for an aggregate $1.1 million increase to the FPA Investors’ pre-existing prepayment shortfall of $0.7 million. Upon execution of the 2024 FPA Amendments, the Company recognized a loss on amendment to forward purchase contract as set forth below (in thousands): | | | | | | | Loss on Amendment | Reduction of subscription receivable | $ | 2,764 | Reduction in forward purchase derivative liabilities | (1,418) | Cash received in connection with the amendments | (950) | Loss on amendment to forward purchase contracts | $ | 396 |
The $0.4 million loss recognized in connection with the 2024 FPA Amendments represents the reduction in cash proceeds the Company may receive under the forward purchase contract, partially offset by the reduction in the forward purchase derivative liability and the shareholder receivable. As a result of the 2024 FPA Amendments, the maximum cash proceeds the Company could receive under the forward purchase contract, reflected in the subscription receivable balance, was lowered. The reduction in the subscription receivable of $2.8 million was caused by (i) the existing 2024 Amended Reset Price provisions as of the effective date of the 2024 FPA Amendments, (ii) the re-designation of 200,000 additional FPA Shares to Bonus Shares, further reducing the total quantity of FPA Shares outstanding, and (iii) the 2024 Amended Prepayment Shortfall, which increased the prepayment shortfall amount by an incremental $1.1 million. In addition to the reduction in the subscription receivable, the Company recognized a corresponding reduction in the fair value of the forward purchase derivative liabilities of $1.4 million. Sales of FPA Shares and Settlements of Forward Purchase Contracts Pursuant to the terms and conditions of the Private Placement Agreements, any sales of the Company’s common stock associated with the Private Placement Agreements may not be treated as sales of Bonus Shares until all FPA Shares are sold, at which point such sales of stock may be considered sales of Bonus Shares. As set forth above in this note, the forward purchase derivative liabilities represent the portion of the subscription receivable that may be released to the FPA Investors rather than the Company. Immediately prior to the settlement of a forward purchase contract, the derivative liability balance is adjusted to the applicable subscription receivable balance less the cash proceeds to be received as of the settlement date, recognized within the change in fair value of forward purchase derivative liabilities. Upon settlement of a forward purchase contract, the respective derivative liability and subscription receivable balances are derecognized and the cash proceeds to be received are recognized by the Company. Refer to Note 9, Fair Value of Financial Instruments, for further discussion. As of March 31, 2024, certain FPA Investors sold an aggregate of 1,768,121 shares of the Company’s common stock to third parties, representing all of the outstanding FPA Shares under the respective agreements. No other sales of FPA Shares occurred during the three months ended March 31, 2024. The following table summarizes the sales of FPA Shares and proceeds to the Company as of March 31, 2024 (in thousands): | | | | | | | Sales of FPA Shares | Total sales of FPA Shares | $ | 2,626 | Shortfall Sales | (1,753) | Proceeds received from sales of FPA Shares | $ | 873 |
The following presents a reconciliation of the subscription receivable and forward purchase derivative liabilities during the three months ended March 31, 2024 (in thousands): | | | | | | | | | | | | | Subscription Receivables | | Forward Purchase Derivative Liabilities | Balance at December 31, 2023 | $ | 17,792 | | $ | 15,804 | Amendment of forward purchase contracts | (2,764) | | (1,418) | Change in fair value of forward purchase derivative liabilities | — | | (535) | Sales and settlement of forward purchase contracts | (4,639) | | (3,766) | Ending balance at March 31, 2024 | $ | 10,389 | | $ | 10,085 |

Warrants |
Warrants As of March 31, 2024, all warrants described below remained outstanding and unexercised. Public Warrants In connection with Graf’s initial public offering (“IPO”), 3,432,286 warrants were issued to Graf’s investors (“Public Warrants”). The Public Warrants, which entitle the registered holder to purchase one share of the Company’s common stock, have an exercise price of $11.50 per warrant, became exercisable 30 days after the completion of the Business Combination, and are set to expire five years from the completion of the Business Combination, or earlier upon redemption. The Public Warrants may be called for redemption at the sole discretion of the Company if the Company’s stock price equals or exceeds $18.00 per share and other certain conditions are met. The Public Warrants are equity classified due to terms indexed to the Company’s own stock and the satisfaction of other equity classification criteria. Private Warrants Concurrently with Graf’s IPO, Graf issued 4,721,533 warrants to Graf Acquisition Partners IV LLC (“Private Warrants”). The terms of the Private Warrants are identical to the Public Warrants with an exercise price of $11.50 per warrant, except that they are subject to certain transfer and sale restrictions and are not optionally redeemable so long as they are held by the initial purchasers or their permitted transferees. Additionally, the Private Warrants are exercisable on a cashless basis. If the Private Warrants are held by a party other than the initial purchasers or their permitted transferees, the Private Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants. The Private Warrants are liability classified due to terms not indexed to the Company’s own stock. As described in Note 8, Related Party Transactions, the Private Warrants are a related party financial instrument. Private Warrants are classified to non-current liabilities because their term ends beyond one year from the latest unaudited condensed consolidated balance sheet date. SPA Warrants Together with the issuance of the Senior Convertible Notes described in Note 6, Convertible Notes, 1,000,000 warrants were issued to NKMAX at an exercise price of $11.50 per warrant (“SPA Warrants”). The terms of the SPA Warrants are identical to the terms of the Public Warrants with redemption at the sole discretion of the Company if the Company’s stock price equals or exceeds $18.00 per share and other certain conditions are met. The SPA Warrants are equity classified due to terms indexed to the Company’s own stock and the satisfaction of other equity classification criteria, including redemption in the Company’s control if the Company’s stock price equals or exceeds $18.00 per share. As described in Note 8, Related Party Transactions, the SPA Warrants are a related party financial instrument. Working Capital Warrants Prior to the Closing, Graf executed drawdowns upon a working capital loan facility. Upon Closing, the $0.8 million balance of the working capital loan facility was settled through the issuance of 523,140 warrants (“Working Capital Warrants”). The terms of the Working Capital Warrants are identical to the terms of the Private Warrants with an exercise price of $11.50 per warrant. The Working Capital Warrants are liability classified due to terms not indexed to the Company’s own stock. As described in Note 8, Related Party Transactions, the Working Capital Warrants are a related party financial instrument. Working Capital Warrants are classified to non-current liabilities because their term ends beyond one year from the latest unaudited condensed consolidated balance sheet date. PIPE Warrants Prior to the Closing, the Company entered into warrant subscription agreements (the “Warrant Subscription Agreements”) with certain investors (“Warrant Investors”), which closed on September 29, 2023. Pursuant to the Warrant Subscription Agreements, the Warrant Investors purchased an aggregate of 10,209,994 warrants, at a purchase price of $1.00 per warrant (“PIPE Warrants”) for total proceeds of $10.2 million. The PIPE Warrants are exercisable for cash (or by “cashless” exercise under certain circumstances) during the five-year period beginning on the Closing. One-third of the PIPE Warrants are exercisable initially at $10.00 per warrant, one-third of the PIPE Warrants are exercisable initially at $12.50 per warrant, and one-third of the PIPE Warrants are exercisable initially at $15.00 per warrant. The initial exercise prices of each tranche are subject to adjustment every 180 days after the Closing based upon declines in trading prices of the Company’s common stock, as well as antidilutive adjustments for stock splits, stock dividends, and the like. In addition, the PIPE Warrants contain a downside protection provision, pursuant to which the Warrant Investors may demand a cashless exchange of certain PIPE Warrants and, to the extent the relevant reference price is less than $1.50 per share, a cash payment calculated as the difference between $1.50 per share and the then-current exercise price multiplied by the applicable number of warrant shares shall be paid to the Warrant Investors. The PIPE Warrants are liability classified due to terms not indexed to the Company’s own stock and their cash settlement provisions. PIPE Warrants are classified to non-current liabilities because their term ends beyond one year from the latest unaudited condensed consolidated balance sheet date. PIPE Warrant Amendment On February 9, 2024, the Company amended their Warrant Subscription Agreement with a Warrant Investor ("PIPE Warrant Amendment") to, among other things, grant the Warrant Investor, (i) the right to exchange each PIPE Warrant for a newly registered share, effectively waiving the original strike price, (ii) a “Most Favored Nation” status with respect to warrant restructuring such that they may amend the terms upon the Company executing a similar transaction with more favorable terms for so long as any subscription warrants remain outstanding, and (iii) certain registration rights. In exchange, the Company received an upfront cash payment of $0.3 million and the right to receive a second cash payment of up to $0.3 million based on the trailing 5-day VWAP following the effective registration of the shares ("Deferred Payment"). The Deferred Payment is reflected within the fair value of the PIPE Warrant derivative liabilities under ASC 815, Derivatives and Hedging. All other terms and conditions remained unchanged. | | | | | | | PIPE Warrant Amendment | Cash proceeds | $ | 250 | Reduction in PIPE Warrant derivative liability | 429 | Gain on amendment of PIPE warrant agreement | $ | 679 |
The reduction in the PIPE Warrant derivative liability was primarily attributable to the removal of the downside protection feature as well as the recognition of the Deferred Payment. Convertible Bridge Loan Warrants Together with the issuance of the Convertible Bridge Loans described in Note 6, Convertible Notes, 1,250,000 warrants were issued to lenders (“Convertible Bridge Loan Warrants”). The Convertible Bridge Loan Warrants, which entitle the registered holder to purchase one share of the Company’s common stock, have an exercise price of $1.50 to $2.00 per warrant, became exercisable on the date of the issuance of the warrant, and are set to expire five years from issuance or earlier upon redemption. Additionally, the Convertible Bridge Loan Warrants are exercisable on a cashless basis if mutually agreed upon with the Company. Some of the warrants also have most favored nation status and reset provisions with respect to new warrant issues and existing warrant restructuring. The Convertible Bridge Loan Warrants are liability classified due to the Company not having a sufficient amount of authorized shares to satisfy the hypothetical conversion of the Convertible Bridge Loans as they do not contain a maximum number of shares that they are convertible into. Such warrants are classified to non-current liabilities because their term ends beyond one year from the latest unaudited condensed consolidated balance sheet date. Convertible 12% Promissory Note Warrants Together with the issuance of the Convertible 12% Promissory Notes described in Note 6, Convertible Notes, 660,000 warrants were issued to lenders (“Convertible 12% Promissory Note Warrants”). The terms of the Convertible 12% Promissory Note Warrants are identical to the Convertible Bridge Loan Warrants, as they entitle the registered holder to purchase one share of the Company’s common stock, have an exercise price of $2.00 per warrant, became exercisable on the date of the issuance of the warrant, and are set to expire five years from issuance or earlier upon redemption. The Convertible 12% Promissory Note Warrants are liability classified due to the Company having an insufficient amount of authorized shares to satisfy the hypothetical conversion of the Convertible 12% Promissory Notes as they do not contain a maximum number of shares that they are convertible into. Such warrants are classified to non-current liabilities because their term ends beyond one year from the latest unaudited condensed consolidated balance sheet date.

Convertible Notes |
Convertible Notes Legacy Convertible Notes From November to December 2019 and from March to September 2023, the Company issued convertible promissory notes for aggregate proceeds of $17.3 million, of which $0.4 million were issued to related parties (“Legacy Convertible Notes”). The convertible notes issued during 2019 and 2023 bore an interest rate of 1.7% and 4.6% per year, respectively. Pursuant to their terms, immediately prior to Closing, all of the Legacy Convertible Notes were converted into 5,579,266 shares of Legacy NKGen common stock, which then converted into 2,278,598 shares of the Company’s common stock at Closing based on the Exchange Ratio. Senior Convertible Notes Prior to the Closing, the Company entered into convertible note subscription agreements (“Securities Purchase Agreement”) with NKMAX for total proceeds of $10.0 million, with a four-year term and an interest rate of 5.0% paid in cash semi-annually or 8.0% paid in kind (“Senior Convertible Notes”), which closed on September 29, 2023. Interest began accruing at Closing and is payable semi-annually in arrears, with interest that is paid in kind (if applicable) increasing the principal amount outstanding on each interest payment date. The Company currently expects to make their interest payments in-kind in lieu of periodic cash payments. The Senior Convertible Notes are convertible at any time, in whole or in part, at NKMAX’s option at a conversion price of $10.00 per share of common stock (subject to anti-dilution adjustments in the event of stock splits and the like). The Senior Convertible Notes have a put option which may be exercised by NKMAX 2.5 years after the issuance of the Senior Convertible Notes. No less than six months after exercise of the put option, the Company will be required to repay all principal and accrued interest of the Senior Convertible Notes. Should the put option remain unexercised, the outstanding principal and accrued interest will be due and payable on September 29, 2027. Additionally, as described in Note 5, Warrants, together with the Securities Purchase Agreement, the SPA Warrants were issued to NKMAX. Accordingly, a relative fair value allocation was applied and discount was recognized on the Senior Convertible Notes as set forth in Note 9, Fair Value of Financial Instruments. There are no financial or non-financial covenants associated with the Senior Convertible Notes. During the three months ended March 31, 2024, the Company recorded $0.2 million of interest expense and discount amortization related to the Senior Convertible Notes. As described in Note 8, Related Party Transactions, the Senior Convertible Notes are a related party financial instrument. The following table presents a reconciliation of the Senior Convertible Notes (in thousands): | | | | | | | Senior Convertible Notes | Balance as of December 31, 2023 | $ | 9,930 | Amortization of discount | 11 | Paid-in-kind interest | 206 | Balance as of March 31, 2024 | $ | 10,147 |
Convertible Bridge Loans From February to March 2024, the Company issued convertible bridge loans to holders ("2024 Convertible Bridge Loans") and related parties ("2024 Related Party Convertible Bridge Loan"), collectively referred to as ("Convertible Bridge Loans") for total proceeds of $0.3 million and $0.4 million, respectively, with a 20.0% premium due at maturity. The Convertible Bridge Loans mature at the earlier of (i) 60 days from the respective issuance dates, (ii) upon a financing event with third parties exceeding between $5.0 million and $10.0 million, depending on the agreement, (iii) the occurrence of any event of default, or (iv) the acceleration of the short term bridge note. The loans are convertible at any time, in whole or in part, at the holder's option into the Company's common stock at a 15.0% discount to the VWAP 10 days prior to conversion, with the conversion being limited to converting at no more than $2.00 per share. Certain Convertible Bridge Loans also entitle the holder to 7,334 shares of the Company's common stock (“Consideration Shares”). Consideration Shares are liability classified until issuance due to the insufficiency of authorized and unissued shares. Additionally, as described in Note 5, Warrants, concurrently with the Convertible Bridge Loans, the Company issued the Convertible Bridge Loan Warrants to holders which were recognized at fair value of $1.4 million. There are no other financial or non-financial covenants associated with the Convertible Bridge Loans. The Company recognized a loss of $0.7 million upon issuance of the Convertible Bridge Loans, Convertible Bridge Loan Warrants and Consideration Shares representing the excess of the $1.4 million initial fair value of the Convertible Bridge Loan Warrants over the $0.7 million proceeds received. Accordingly, a discount was recognized on the Convertible Bridge Loans. Refer to Note 9, Fair Value of Financial Instruments. The Company accretes the balance of the Convertible Bridge Loans on a straight-line basis to its repayment amount through interest expense. During the three months ended March 31, 2024, the Company recorded $0.2 million of interest expense and discount amortization related to the 2024 Convertible Bridge Loans and $0.4 million interest expense and discount amortization related to the 2024 Related Party Convertible Bridge Loan. As of March 31, 2024, $0.2 million remained to be accreted through interest expense on the Convertible Bridge Loans. No interest expense was incurred for the Convertible Bridge Loans during the three months ended March 31, 2023.

Convertible Notes Legacy Convertible Notes From November to December 2019 and from March to September 2023, the Company issued convertible promissory notes for aggregate proceeds of $17.3 million, of which $0.4 million were issued to related parties (“Legacy Convertible Notes”). The convertible notes issued during 2019 and 2023 bore an interest rate of 1.7% and 4.6% per year, respectively. Pursuant to their terms, immediately prior to Closing, all of the Legacy Convertible Notes were converted into 5,579,266 shares of Legacy NKGen common stock, which then converted into 2,278,598 shares of the Company’s common stock at Closing based on the Exchange Ratio. Senior Convertible Notes Prior to the Closing, the Company entered into convertible note subscription agreements (“Securities Purchase Agreement”) with NKMAX for total proceeds of $10.0 million, with a four-year term and an interest rate of 5.0% paid in cash semi-annually or 8.0% paid in kind (“Senior Convertible Notes”), which closed on September 29, 2023. Interest began accruing at Closing and is payable semi-annually in arrears, with interest that is paid in kind (if applicable) increasing the principal amount outstanding on each interest payment date. The Company currently expects to make their interest payments in-kind in lieu of periodic cash payments. The Senior Convertible Notes are convertible at any time, in whole or in part, at NKMAX’s option at a conversion price of $10.00 per share of common stock (subject to anti-dilution adjustments in the event of stock splits and the like). The Senior Convertible Notes have a put option which may be exercised by NKMAX 2.5 years after the issuance of the Senior Convertible Notes. No less than six months after exercise of the put option, the Company will be required to repay all principal and accrued interest of the Senior Convertible Notes. Should the put option remain unexercised, the outstanding principal and accrued interest will be due and payable on September 29, 2027. Additionally, as described in Note 5, Warrants, together with the Securities Purchase Agreement, the SPA Warrants were issued to NKMAX. Accordingly, a relative fair value allocation was applied and discount was recognized on the Senior Convertible Notes as set forth in Note 9, Fair Value of Financial Instruments. There are no financial or non-financial covenants associated with the Senior Convertible Notes. During the three months ended March 31, 2024, the Company recorded $0.2 million of interest expense and discount amortization related to the Senior Convertible Notes. As described in Note 8, Related Party Transactions, the Senior Convertible Notes are a related party financial instrument. The following table presents a reconciliation of the Senior Convertible Notes (in thousands): | | | | | | | Senior Convertible Notes | Balance as of December 31, 2023 | $ | 9,930 | Amortization of discount | 11 | Paid-in-kind interest | 206 | Balance as of March 31, 2024 | $ | 10,147 |

The Convertible Bridge Loans mature at the earlier of (i) 60 days from the respective issuance dates, (ii) upon a financing event with third parties exceeding between $5.0 million and $10.0 million, depending on the agreement, (iii) the occurrence of any event of default, or (iv) the acceleration of the short term bridge note. The loans are convertible at any time, in whole or in part, at the holder's option into the Company's common stock at a 15.0% discount to the VWAP 10 days prior to conversion, with the conversion being limited to converting at no more than $2.00 per share. Certain Convertible Bridge Loans also entitle the holder to 7,334 shares of the Company's common stock (“Consideration Shares”). Consideration Shares are liability classified until issuance due to the insufficiency of authorized and unissued shares. Additionally, as described in Note 5, Warrants, concurrently with the Convertible Bridge Loans, the Company issued the Convertible Bridge Loan Warrants to holders which were recognized at fair value of $1.4 million. There are no other financial or non-financial covenants associated with the Convertible Bridge Loans. The Company recognized a loss of $0.7 million upon issuance of the Convertible Bridge Loans, Convertible Bridge Loan Warrants and Consideration Shares representing the excess of the $1.4 million initial fair value of the Convertible Bridge Loan Warrants over the $0.7 million proceeds received. Accordingly, a discount was recognized on the Convertible Bridge Loans. Refer to Note 9, Fair Value of Financial Instruments.

Related-Party Transactions |
Related Party Transactions Founder Shares Contemporaneously with the execution of the Merger Agreement, Graf and NKGen entered into an amended and restated sponsor support and lockup agreement (“Amended and Restated Sponsor Support and Lockup Agreement”). In connection with the Amended and Restated Sponsor Support and Lockup Agreement, of the 4,290,375 shares of Graf formerly held by Graf’s sponsor and insiders (“Founder Shares”): (i) 1,773,631 shares were forfeited, (ii) 1,173,631 shares became restricted shares subject to vesting conditions (“Deferred Founder Shares”), and (iii) the remaining 1,343,113 shares are subject to trading restrictions for up to two years and continue to be outstanding and fully vested shares. Deferred Founder Shares do not have voting rights, do not participate in dividends and are not transferable. During the vesting period of five years from Closing (“Vesting Period”), if the trading price or price per share consideration upon a change in control for common stock is greater than or equal to $14.00 at any 20 trading days in a 30 consecutive trading-day period, then 873,631 Deferred Founder Shares will immediately vest; and if greater than or equal to $20.00 at any 20 trading days in a 30 consecutive trading-day period, then an additional 300,000 Deferred Founder Shares will immediately vest. In the event there is a sale of the Company, then immediately prior to the consummation of such sale, the calculated Acquiror Sale Price, as defined in the agreement, will take into account the number of Deferred Founder Shares that will vest upon a change in control. Upon the expiration of the Vesting Period, unvested Founder Shares will be forfeited and cancelled for no consideration.

Fair Value Disclosures [Abstract] |

Fair Value of Financial Instruments |
Fair Value of Financial Instruments The Company accounts for the fair value of its financial instruments under the framework established by US GAAP which defines fair value and expands disclosures about fair value measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The standard describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value. The Company’s management used the following methods and assumptions to estimate the fair value of its financial instruments: Level 1 — Quoted prices in active markets for identical assets or liabilities the Company has the ability to access at the measurement date. Level 2 — Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of assets or liabilities. Level 3 — Pricing inputs that are unobservable, supported by little or no market activity and are significant to the fair value of the assets or liabilities. The carrying amounts of the Company’s financial assets and financial liabilities are considered to be representative of their respective fair values because of the short-term nature of those instruments. The Company does not measure assets at fair value on a recurring basis. Liabilities measured at fair value on a recurring basis as of March 31, 2024 are as follows (in thousands): | | | | | | | | | | | | | | | | | | | | | | | | | Fair Value Measurements at Reporting Date Using | | Balance as of March 31, 2024 | | Level 1 | | Level 2 | | Level 3 | Convertible 12% Promissory Notes | $ | 728 | | | $ | — | | | $ | — | | | $ | 728 | | Private Warrants | 803 | | | — | | | — | | | 803 | | Working Capital Warrants | 89 | | | — | | | — | | | 89 | | PIPE Warrants | 19,704 | | | — | | | — | | | 19,704 | | Convertible Bridge Loan Warrants | 1,822 | | | — | | | — | | | 1,822 | | Convertible 12% Promissory Note Warrants | 942 | | | — | | | — | | | 942 | | Forward Purchase Derivative Liabilities | 10,085 | | | — | | | — | | | 10,085 | | Consideration Shares | 14 | | | 14 | | | — | | | — | | Total | $ | 34,187 | | | $ | 14 | | | $ | — | | | $ | 34,173 | |
In addition to items that are measured at fair value on a recurring basis, the Company also has liabilities that are measured at fair value on a nonrecurring basis and therefore are not included in the tables above. Liabilities that are measured at fair value on a nonrecurring basis as of March 31, 2024 include the Senior Convertible Notes. The Senior Convertible Notes were determined to be in-scope of ASC 470, Debt. Accordingly, this instrument will not be measured at fair value on a recurring basis as the fair value measurement of this instrument was for purposes of the relative fair value allocation as the Senior Convertible Notes were issued together with the SPA Warrants. Legacy Convertible Notes For the three months ended March 31, 2023, the Company recognized $1.5 million of expense associated with the change in fair value of the Legacy Convertible Notes. The Legacy Convertible Notes converted at Closing on September 29, 2023. The fair value of the notes immediately prior to their conversion at Closing was based upon the fair value of the 2,278,598 shares of the Company’s common stock issued upon their conversion totaling $18.9 million, at a per share value of $8.30 based upon the fair value of the Company’s common stock at Closing. Convertible 12% Promissory Notes The following table presents a reconciliation of the Convertible 12% Promissory Notes (in thousands):
| | | | | |
| Convertible 12% Promissory Notes | Balance as of December 31, 2023 | $ | — | | Issuance | 250 | | Change in fair value | $ | 478 | | Balance as of March 31, 2024 | $ | 728 | |
The fair value of the Convertible 12% Promissory Notes was measured using a binomial lattice model. A binomial stock lattice model generates two probable outcomes of stock price -one up and another down -emanating at each point in time or "node", starting from the valuation date until the maturity date. This lattice generates a distribution of stock price. Based on the stock price at each corresponding node, the value of the Notes was determined by evaluating the optimal decision that a holder and/or the issuer would make to maximize its payoff (the "Decision Tree"). At maturity, the value of the notes was calculated as the maximum between the principal amount and the conversion value. At each node prior to maturity, the lattice model determines whether the notes would be (i) converted by the holder, or (ii) held by the holder, based on the payoff related to each decision. Volatility in the model was estimated from historical equity volatility, median asset volatility of comparable companies, and was adjusted using the Company's capital structure. The cost of debt used in discounting the Notes was estimated based on (i) market yield curve corresponding to the estimated synthetic credit rating of the Company, and (ii) observed market spreads of publicly traded comparable debt with similar credit rating and industry as that of the Company. The following unobservable assumptions were used in determining the fair value of the Convertible 12% Promissory Notes at March 31, 2024: | | | | | | Credit spread | 27.5 | % | Equity volatility | 45.0 | % |
Liability Classified Warrants The following table represent a reconciliation of all liability classified warrants (in thousands): | | | | | | | | | | | | | | | | | | | | | | Private Warrants | Working Capital Warrants | Convertible Bridge Loan Warrants | Convertible 12% Promissory Note Warrants | PIPE Warrants | Total | Balance December 31, 2023 | $ | 377 | | $ | 42 | | $ | — | | $ | — | | $ | 25,339 | | $ | 25,758 | | Issuances | — | — | 1,424 | 323 | — | | 1,747 | | Change in fair value in connection with PIPE Warrants Amendment | — | — | — | — | (429) | | (429) | | Change in fair value | 426 | 47 | 398 | 619 | (5,206) | | (3,716) | | Balance as of March 31, 2024 | $803 | $89 | $1,822 | $942 | $ | 19,704 | | $ | 23,360 | |
The fair value of the Private Warrants, Working Capital Warrants, Convertible Bridge Loan Warrants, and Convertible 12% Promissory Note Warrants were measured using a Black-Scholes model. The estimated fair value of the liability classified warrants was determined using Level 3 inputs. Inherent in a Black-Scholes model are assumptions related to expected stock-price volatility, expected life, risk-free interest rate and dividend yield. The Company estimates the volatility of its liability classified warrants based on implied volatility from the Company’s traded warrants and from historical volatility of select peer company’s common stock that matches the expected remaining life of each class of warrants as well as historical volatility of select peer company’s traded options. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a maturity similar to the expected remaining life of each class of warrants. The expected life of each class of warrants is assumed to be equivalent to their remaining contractual term. The dividend rate is based on the historical rate, which the Company anticipates remaining at zero. The fair value of the PIPE Warrants was valued using level three inputs and was estimated using a Monte Carlo simulation approach. The Company’s common share price was assumed to follow a Geometric Brownian Motion over a period from the Valuation Date to the Expiration Date. The breadth of all possible scenarios was captured in an estimate of volatility, based on comparable companies’ historical equity volatilities, considering differences in their capital structure. For each simulation path, the test price and Reset Price were calculated based on the daily stock price during the measurement period. On each reset date, the downside protection condition was assessed to see if it was met by comparing the test price with the downside protection threshold price. The value of each tranche of warrants was then computed, factoring in any downside protection shares and downside protection cash, if applicable. The average value across this range of possible scenarios, discounted to present using the risk-free rate, was used as the fair value of the PIPE Warrants. The change in fair value of the PIPE Warrants was primarily attributable to select features of the Warrant Subscription Agreements, including strike price resets and downside protection which results in decreased value as the Company’s stock price volatility increases and the stock price declines. The following unobservable assumptions were used in determining the fair value of the liability classified warrants at March 31, 2024 and December 31, 2023: | | | | | | | | | | At March 31, 2024 | At December 31, 2023 or closing date if later | Private Warrants and Working Capital Warrants | | | Private Warrants’ volatility | 55.5 | % | 35.3 | % | Dividend yield (per share) | — | | — | | Convertible Bridge Loan Warrants | | | Volatility | 100.0 | % | 105.0 | % | Dividend yield (per share) | — | | — | | Convertible 12% Promissory Note Warrants | | | Equity volatility | 100.0 | % | — | | PIPE Warrants | | | Credit spread | 19.0 | % | 12.7 | % | Equity volatility | 105.0 | % | 100.0 | % |
The following unobservable assumptions were used in determining the fair value of the PIPE Warrants immediately before and after modification at February 9, 2024: | | | | | | Credit spread | 17.8 | % | Equity volatility | 105.0 | % |
Forward Purchase Derivative Liabilities The forward purchase derivative liabilities were recognized at Closing on September 29, 2023. The fair value as of March 31, 2024 was $10.1 million. Refer to Note 4, Private Placements, for a reconciliation of the forward purchase derivative liabilities. The fair value of the forward purchase derivative liabilities was estimated using a Monte Carlo simulation approach. The Company’s common share price was simulated with daily time steps for a range of various possible scenarios. The breadth of all possible scenarios was captured in an estimate of volatility, based on comparable companies’ historical equity volatilities, considering differences in their capital structure. The simulated prices were compared against the settlement adjustment features of the Forward Purchase Agreements. Under each simulated scenario of future stock price, the Company calculated the value of the forward purchase derivative liability arrangement. The average value across this range of possible scenarios, discounted to present using the risk-free rate, was used as the fair value of the forward purchase derivative liabilities. The following unobservable assumptions were used in determining the fair value of the forward purchase derivative liabilities at the respective balance sheet and amendment dates: | | | | | | | | | | | | | | | | | | | | | | | | | March 31, 2024 | | February 21, 2024 | | January 19, 2024 | | December 31, 2023 | Dividend yield | 0.0 | % | | 0.0 | % | | 0.0 | % | | 0.0 | % | Equity volatility | 120.0 | % | | 145.0 | % | | 105.0 | % | | 115.0 | % |
Consideration Shares The Consideration Shares are recorded at fair value on a recurring basis within Accounts payable and accrued expenses. These shares are liability-classified until issuance and relate to the Convertible Bridge Loans. The liability associated with these Consideration Shares is carried at fair value, demonstrating the obligation to the lenders. The estimated fair value of the Consideration Shares is based on quoted market prices that are readily and regularly available in an active market. Relative Fair Values The Convertible 12% Promissory Notes were issued together with the Convertible 12% Promissory Note Warrants. Thus, each instrument was recorded at its fair value, limited to a relative fair value based upon the percentage of its fair value to the total fair value based on the transaction price of $0.6 million at issuance. The Company elected to record the Convertible 12% Promissory Notes at fair value under ASC 825, Financial Instruments. The relative fair value at initial recognition for the Convertible 12% Promissory Notes and Convertible 12% Promissory Note Warrants was $0.3 million and $0.3 million, respectively. The stand-alone fair value of the Convertible 12% Promissory Notes and Convertible 12% Promissory Note Warrants was $0.7 million and $0.9 million as of March 31, 2024.
Residual Fair Values The Convertible Bridge Loans were issued together with the Convertible Bridge Loan Warrants. The Convertible Bridge Loan Warrants were recorded at fair value, under ASC 815, Derivatives and Hedging, and the Convertible Bridge Loans were determined to be in-scope of 470, Debt. Accordingly, the Company recorded the fair value of the Convertible Bridge Loan Warrants at issuance, with the residual amount of the proceeds allocated to the convertible debt instrument. The fair value of the Convertible Bridge Loan Warrants was treated as a discount to the Convertible Bridge Loans, which will be amortized to interest expense over the term of the Convertible Bridge Loans. The stand-alone fair value at initial recognition for the Convertible Bridge Loan Warrants was $1.4 million. Less than $0.1 million residual value allocated to the Convertible Bridge Loans. The Company received total proceeds of $0.7 million from the issuance of the Convertible Bridge Loans. Accordingly, upon issuance, the Company recognized a loss of $0.7 million within loss on issuance of convertible bridge loans unaudited condensed consolidated statements of operations representing the fair value of the Convertible Bridge Loan Warrants over the proceeds received for the issuance of the Convertible Bridge Loans, Convertible Bridge Loan Warrants and Consideration Shares.

Stockholders' Equity |
Stockholder’s Equity Reverse Recapitalization As described in Note 2, Summary of Significant Accounting Policies, all historical equity data, including stock option data, in these unaudited condensed consolidated financial statements has been retrospectively adjusted by the Exchange Ratio to reflect the reverse recapitalization that occurred on September 29, 2023. Common Stock As of March 31, 2024, the Company had authorized 500,000,000 shares of common stock, par value $0.0001 per share. As of March 31, 2024, 22,388,976 shares of common stock were issued and outstanding, and 477,611,024 shares of common stock were reserved for future issuance. Preferred Stock As of March 31, 2024, the Company had authorized 10,000,000 shares of preferred stock, par value $0.0001. As of March 31, 2024, zero shares of preferred stock were issued or outstanding. Employee Stock Purchase Plan Upon consummation of the Business Combination, the Company adopted an employee stock purchase plan (“ESPP”). The maximum number of shares of the Company’s common stock that may be issued under the ESPP is 3.0% of the fully diluted common stock of the Company, determined as of immediately following Closing. Such maximum number of shares is subject to automatic annual increases. The Company’s employees and the employees of any designated affiliates may participate in the ESPP. The purchase price of the ESPP shares is 85.0% of the lesser of the fair market value of the Company’s common stock on the first day of an offering or on the applicable date of purchase. As of March 31, 2024, there were no transactions with respect to the ESPP. 2019 Plan The Company’s 2019 Plan (“2019 Plan”) became effective on October 23, 2019. The 2019 Plan provides for the grant of incentive stock options, non-qualified stock options, stock appreciation rights, restricted stock unit awards and performance share awards to employees, directors, and consultants of the Company. As of March 31, 2024, the Company has only issued stock options. Stock options granted under the 2019 Plan expire no later than ten years from the date of grant and generally vest over a four-year period, with vesting occurring at a rate of 25.0% at the end of the first and thereafter in 36 equal monthly installments, or in the case of awards granted to board members, on a monthly basis over three or four years. In general, vested options expire if not exercised within three months after termination of service. 2023 Plan Upon consummation of the Business Combination, the Company adopted the 2023 equity incentive plan (“2023 Plan”). The maximum number of shares of common stock that may be issued under the 2023 Plan is 12.0% of the fully diluted common stock of the Company, determined as of immediately following Closing. Such maximum number of shares is subject to automatic annual increases. Under the 2023 Plan, restricted shares and stock options with service or performance based conditions may be granted to employees and nonemployees. Upon the effective date of the 2023 Plan, the Company may not grant any additional awards under the 2019 Plan. As of March 31, 2024, certain awards to executives and non-employee directors were granted under the 2023 Plan. Stock options granted under the 2023 Plan expire no later than ten years from the date of grant and generally vest on a monthly basis over three or four years. In general, vested options expire if not exercised within three months after termination of service. The fair value of each employee and non-employee stock option grant under the 2019 Plan and 2023 Plan are estimated on the date of grant using the Black-Scholes option-pricing model. Due to the Company’s limited operating history and a lack of company-specific historical and implied volatility data, the Company estimated expected volatility based on the historical volatility of a group of similar companies that are publicly traded. The historical volatility data was computed using the daily closing prices for the selected companies’ shares during the equivalent period of the calculated expected term of the stock-based awards. Due to the lack of historical exercise history, the expected term of the Company’s stock options for employees has been determined utilizing the “simplified” method for awards. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected term of the award. The expected dividend yield is zero since the Company has never paid cash dividends and does not expect to pay any cash dividends in the foreseeable future. A summary of the Company’s stock option activity for the three months ended March 31, 2024 is as follows: | | | | | | | | | | | | | Number of Stock Options | | Weighted Average Exercise Price | Outstanding as of December 31, 2023 | 2,078,986 | | $ | 6.25 | | Granted | 2,295,000 | | 1.62 | | Forfeited | (109,725) | | 6.65 | | Exercised | — | | — | | Outstanding as of March 31, 2024 | 4,264,261 | | $ | 3.75 | |
The weighted average assumptions used in the Black-Scholes option pricing model to determine the fair value of stock option grants for the three months ended March 31, 2024 were as follows: | | | | | | | 2023 Plan | Common stock fair value | $ | 1.62 | | Risk-free interest rate | 4.2 | % | Expected volatility | 92.0 | % | Expected term (in years) | 6.9 | Expected dividend yield | — | % |
Stock options outstanding, vested and expected to vest and exercisable as of March 31, 2024 are as follows: | | | | | | | | | | | | | | | | | | | | | | | | | Number of Stock Options | | Weighted Average Remaining Contractual Life (Years) | | Weighted- Average Exercise Price | | Total Aggregate Intrinsic Value (in thousands) | Outstanding as of December 31, 2023 | 2,078,986 | | 8.86 | | $ | 6.25 | | | $ | 317 | | Outstanding as of March 31, 2024 | 4,264,261 | | 3.97 | | $ | 3.75 | | | $ | 825 | | Vested and expected to vest as of March 31, 2024 | 4,264,261 | | 3.97 | | $ | 3.75 | | | $ | 825 | | Exercisable as of March 31, 2024 | 1,038,115 | | 8.68 | | $ | 4.31 | | | $ | 289 | |
Intrinsic value is calculated as the difference between the exercise price of the underlying options and the estimated fair value of the common stock for the options that had exercise prices that were lower than the per share fair value of the common stock on the related measurement date. The aggregate fair value of stock options vested during the three months ended March 31, 2024 was $3.8 million. As of March 31, 2024, the total unrecognized stock-based compensation related to unvested stock option awards granted was $12.4 million, which the Company expects to recognize over a remaining weighted- average period of approximately 3.1 years. Stock-based compensation expense, recognized in the Company’s unaudited condensed consolidated statements of operations and comprehensive loss for the 2019 Plan was recorded as follows (in thousands): | | | | | | | | | | | | | Three Months Ended March 31 | | 2024 | | 2023 | Research and development | $ | 145 | | | $ | 330 | | General and administrative | 972 | | | 928 | | Total stock-based compensation expense | $ | 1,117 | | | $ | 1,258 | |

Commitments and Contingencies |
Commitments and Contingencies Leases In February 2018, the Company entered into an operating lease agreement for office space located in 10 Pasteur, Irvine with a lease term of approximately five years. Rent payments commenced in February 2018. The lease expired on February 5, 2023. In October 2021, the Company entered into an operating lease agreement for office space located in 19700 Fairchild with a lease term of approximately two years with an option to extend the term for one two-year term, which at the time was not reasonably assured of exercise and therefore, not included in the lease term. Rent payments commenced in December 2021. The lease expired on December 31, 2023. On November 9, 2023, the Company entered into a new operating lease agreement for office space located in Irvine, California with a lease term of approximately three years and rent payments commencing on January 1, 2024. The lease commencement date is January 1, 2024. As of March 31, 2024, the Company recorded an aggregate ROU asset of $0.5 million with an accumulated amortization of less than $0.1 million in the unaudited condensed consolidated balance sheets as operating lease right of use assets, net, and an aggregate lease liability of $0.5 million in the balance sheet, which is comprised of $0.2 million operating lease liability, current and $0.3 million of operating lease liability, non-current. As of March 31, 2024, the weighted-average remaining lease term is 2.8 years and the weighted-average discount rate is 22.4%. Future minimum lease payments under the new office lease are as follows (in thousands): | | | | | | | Minimum lease payments | 2024 (excluding the three months ended 3/31/2024) | $ | 176 | | 2025 | 242 | | 2026 | 249 | | Total operating lease liability | $ | 667 | |
License Agreements The Company has entered into exclusive license agreements with NKMAX, as amended in October 2021, April 2023 and August 2023 (“Intercompany License”), pursuant to which the Company acquired certain intellectual property for the development of treatments for cancer and other fields of use. Pursuant to each license agreement, as consideration for an exclusive license to the intellectual property, the Company paid an upfront fee of $1.0 million (“Licensed Technology”), which was recognized as research and development expense in the period paid as the license has no alternative future use. Additionally, the Company is also required to pay one-time milestone payments for the first receipt of regulatory approval by the Company or any of its affiliates for a Licensed Technology in the following jurisdictions (and amounts): the United States ($5.0 million), the European Union (“EU”) ($4.0 million), and four other countries ($1.0 million each). The Company is obligated to pay a mid-single digit royalty on net sales of Licensed Technology by it, its affiliates or its sublicensees, subject to customary reductions. The Company is also required to pay a percentage of its sublicensing revenue ranging from a low double-digit percentage to a mid-single digit percentage. As of March 31, 2024, the Company has not paid any milestone payments and no sales of Licensed Technology have occurred. Litigation The Company is subject to legal proceedings and claims, which arise in the ordinary course of business. The Company is not subject to any currently pending legal matters or claims that would have a material adverse effect on its financial position, results of operations or cash flows. In the normal course of business, the Company enters into contracts and agreements that contain a variety of representations and warranties and provide for general indemnifications. The Company’s exposure under these agreements is unknown because it involves claims that may be made against the Company in the future but have not yet been made. The Company accrues a liability for such matters when it is probable that future expenditures will be made, and such expenditures can be reasonably estimated. No amounts were accrued as of March 31, 2024 and December 31, 2023.

In connection with the three additional tranches, the Company may issue an aggregate of up to 750,000 additional shares of common stock and issue warrants that entitle holders to an aggregate of up to 990,000 shares of common stock at the lender’s sole discretion. Each additional promissory note will have identical terms as the original note, and each additional common stock purchase warrant will have identical terms as the original warrant.

Accounting Policies [Abstract] |
|
Basis of Presentation |
Basis of Presentation NKMAX held a majority of the voting power of Legacy NKGen before the Business Combination and continued to hold a majority of the voting power of the Company after the Business Combination. Therefore, as there was no change in control, the Business Combination was accounted for as a common control transaction with respect to Legacy NKGen along with a reverse recapitalization of the Company. Accordingly, for accounting purposes, the financial statements of the Company represent a continuation of the financial statements of Legacy NKGen with the Business Combination being treated as the equivalent of Legacy NKGen issuing shares for the net assets of Graf, accompanied by a recapitalization. The net assets of Graf were recognized as of the Closing at historical cost, with no goodwill or other intangible assets recorded. Operations prior to the Business Combination are presented as those of Legacy NKGen and the accumulated deficit of Legacy NKGen has been carried forward after Closing. Upon the consummation of the Business Combination, all of Legacy NKGen’s equity was converted into equity of the Company based upon an exchange ratio (“Exchange Ratio”). In addition, all stock options of Legacy NKGen were converted using the Exchange Ratio into options exercisable for shares of the Company with the same terms and vesting conditions. The Exchange Ratio as of September 29, 2023, the date of Closing, was approximately 0.408. All periods prior to the Business Combination have been retrospectively adjusted using the Exchange Ratio to reflect the reverse recapitalization. In connection with the reverse recapitalization treatment of the Business Combination, all issued and outstanding securities of Graf upon Closing were treated as issuances of the Company upon the consummation of the Business Combination. The accompanying financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) and generally accepted accounting principles in the United States of America (“US GAAP”). The Company maintains its accounting records under the accrual method of accounting in conformity with US GAAP. The condensed consolidated balance sheet as of December 31, 2023 included herein was derived from the audited financial statements as of that date. Certain information and disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such regulations. Accordingly, these unaudited condensed consolidated financial statements and accompanying footnotes should be read in conjunction with NKGen’s financial statements as of and for the year ended December 31, 2023. The results for the interim periods are not necessarily indicative of results for the full year. In the opinion of management, all adjustments, of a normal recurring nature, considered necessary for a fair presentation have been included in the unaudited condensed consolidated financial statements. The Company believes that the disclosures provided herein are adequate to prevent the information presented from being misleading.
|
Principles of Consolidation |
Principles of Consolidation The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiary. All significant intercompany balances and transactions have been eliminated in consolidation.
|
Use of Estimates |
Use of Estimates The preparation of unaudited condensed consolidated financial statements in accordance with US GAAP requires management to make estimates and assumptions that impact the reported amounts of certain assets and liabilities, certain disclosures at the date of the unaudited condensed consolidated financial statements, as well as the reported amounts of revenues and expenses during the reporting period. The most significant estimates in the Company’s unaudited condensed consolidated financial statements include, but are not limited to, accrued clinical and research and development expenses, legacy convertible notes, convertible 12% promissory notes, senior convertible promissory notes due to related parties, forward purchase derivative liabilities, derivative warrant liabilities, derivative warrant assets, common stock, and equity awards. These estimates and assumptions are based upon historical experience, knowledge of current events, and various other factors believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the recording of expenses that are not readily apparent from other sources. Actual results could differ materially from those estimates.
|
Restricted Cash |
Restricted Cash Restricted cash consists of funds that are contractually restricted due to a revolving line of credit, which was entered into during June 2023. In accordance with the terms of the revolving line of credit, the Company was required to maintain $15.0 million in cash balances with the lender from March 31, 2024 until repayment of all principals and other payables to the lender under the revolving line of credit was made as additional collateral for the borrowings. In April 2024, the lender subsequently waived the minimum cash deposit requirement in exchange for the Company's agreement to use the lender as their primary banking relationship. As of both March 31, 2024 and December 31, 2023, $0.3 million in restricted cash was recorded on the unaudited condensed consolidated balance sheet. The Company includes its restricted bank deposits in cash, cash equivalents and restricted cash when reconciling beginning-of-period and end-of-period total amounts shown on the unaudited condensed consolidated statements of cash flows for the three months ended March 31, 2024.
|
Deferred Debt Issuance Costs / Debt |
Deferred Debt Issuance Costs Costs incurred through the issuance of the revolving line of credit to parties who are providing short-term financing availability are reflected as deferred debt issuance costs. These costs are generally amortized to interest expense over the life of the financing instrument using the effective interest rate method or other methods approximating the effective interest method.Debt For convertible debt instruments that are not considered liabilities under ASC 480 or ASC 815, the Company applies ASC 470, Debt, for the accounting of such instruments, including any premiums or discounts. The Company’s bridge loans, senior convertible promissory notes, and convertible bridge loans accounted for under ASC 470. Accrued interest paid-in-kind is added to the carrying amount of the Company’s senior convertible promissory notes. The Company accretes the balance of the Convertible Bridge Loans on a straight-line basis to its repayment amount through interest expense.
|
Hybrid Instruments |
Hybrid Instruments The Company follows Financial Accounting Standards Board (“FASB”) Accounting Standard Codification (“ASC”) 480, Distinguishing Liabilities from Equity, when evaluating the accounting for its hybrid instruments. A financial instrument that embodies an unconditional obligation, or a financial instrument other than an outstanding share that embodies a conditional obligation, that the issuer must or may settle by issuing a variable number of its equity shares shall be classified as a liability (or an asset in some circumstances) if, at inception, the monetary value of the obligation is based solely or predominantly on any one of the following: (a) a fixed monetary amount known at inception; (b) variations in something other than the fair value of the issuer’s equity shares; or (c) variations inversely related to changes in the fair value of the issuer’s equity shares. Hybrid instruments meeting these criteria are not further evaluated for any embedded derivatives and are carried as a liability at fair value at each balance sheet date.
|
Derivative Instruments |
Derivative Instruments FASB ASC 815, Derivatives and Hedging Activities, requires companies to bifurcate certain features from their host instruments and account for them as free-standing derivative financial instruments should certain criteria be met. The Company does not use derivative instruments to hedge exposures to interest rate, market, or foreign currency risks. The Company evaluates its financial instruments to determine whether such instruments are derivatives or contain features that qualify as embedded derivatives. Embedded derivatives must be separately measured from the host contract if all the requirements for bifurcation are met. The assessment of the conditions surrounding the bifurcation of embedded derivatives depends on the nature of the host contract and the features of the derivatives. Bifurcated embedded derivatives are recognized at fair value, with changes in fair value recognized in the unaudited condensed consolidated statements of operations and comprehensive loss each period. Bifurcated embedded derivatives are classified with the related host contract in the Company’s unaudited condensed consolidated balance sheets. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is re-assessed at the end of each reporting period.
|
Subscription and Shareholder Receivables |
Subscription and Shareholder Receivables The Company records stock issuances at the effective date. If the amounts are not funded upon issuance, the Company records a subscription receivable or shareholder receivable as an asset on the balance sheet. When subscription receivables or shareholder receivables are not received prior to the balance sheet date in satisfaction of the requirements under ASC 505, Equity, the subscription or shareholder receivable is reclassified as a contra account to stockholder’s equity (deficit) on the balance sheet. Shareholder receivables represent amounts due from shareholders. If the shareholder does not fund the receivable prior to the balance sheet date, the Company records a receivable that is reclassified as a contra account to stockholder’s deficit on the balance sheet.
|
Impairment of Long-Lived Assets |
Impairment of Long-Lived Assets The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate the carrying amount of an asset, or asset group, may not be recoverable. Recoverability is measured by a comparison of the carrying amount of an asset or asset group to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset or asset group exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset or asset group exceeds the fair value of the asset or asset group. The Company has not recognized any impairment losses for the three months ended March 31, 2024 and 2023.
|
Fair Value Option |
Fair Value Option In lieu of bifurcation, on an instrument-by-instrument basis, the Company may elect the fair value option for certain financial instruments that meet the required criteria under ASC 825, Financial Instruments. The Company elected the fair value option for both its legacy convertible notes and convertible 12% promissory notes, which met the required criteria under ASC 825, Financial Instruments. Interest expense associated with both the legacy convertible and convertible 12% promissory notes is included in the change in fair value of such instruments.
|
Fair Value of Financial Instruments |
Fair Value of Financial Instruments The Company accounts for the fair value of its financial instruments under the framework established by US GAAP which defines fair value and expands disclosures about fair value measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The standard describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value. These estimates may be subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Level 1 — Quoted prices in active markets for identical assets or liabilities the Company has the ability to access at the measurement date. Level 2 — Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of assets or liabilities. Level 3 — Pricing inputs that are unobservable, supported by little or no market activity and are significant to the fair value of the assets or liabilities. Transfers to/from Levels 1, 2, and 3 are recognized at the beginning of the reporting period. There were no transfers to/from Levels 1, 2, and 3 during three months ended March 31, 2024 and 2023. ASC 820, Fair Value Measurement, states that in many cases, the transaction price will equal the fair value (for example, that might be the case when on the transaction date, the transaction to buy an asset takes place in the market in which the asset is sold). In determining whether a transaction price represents the fair value at initial recognition, the Company considers various factors such as whether the transaction was between related parties, is a forced transaction, or whether the unit of account for the transaction price does not represent the unit of account for the measured instrument. The Company does not measure assets at fair value on a recurring basis. The Company's liabilities that are measured at fair value on a recurring basis are its liability classified warrants, convertible 12% promissory notes, and forward purchase derivative liabilities. Refer to Note 9, Fair Value of Financial Instruments, for further discussion regarding the Company’s fair value measurements. The carrying value of the Company’s related party loans approximates fair value as the stated interest rate approximates market rates for similar loans and due to the short-term nature of such loans, which are due within three years or less from issuance. The carrying value of the Company’s cash, restricted cash, accounts payable, accrued expenses, bridge loans, convertible bridge loans, other current liabilities, and revolving line of credit approximates fair value primarily due to the short-term nature of such accounts.
|
Leases |
Leases The Company accounts for its leases under ASC 842, Leases. The operating lease right-of-use (“ROU”) asset represents the Company’s right to use an underlying asset during the lease term, and operating lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating leases are included in the ROU asset, current operating lease liabilities, and non-current operating lease liabilities in the accompanying condensed consolidated balance sheets. The operating lease ROU asset and lease liabilities are initially recognized based on the present value of the future minimum lease payments over the lease term at commencement date calculated using the Company’s incremental borrowing rate applicable to the lease asset, unless the implicit rate is readily determinable. The operating lease ROU asset also includes any lease payments made at or before lease commencement and exclude any lease incentives received. The Company determines the lease term as the noncancelable period of the lease and may include options to extend or terminate the lease when it is reasonably certain the Company will exercise that option. Leases with a term of 12 months or less are not recognized in the balance sheet. The Company’s leases do not contain any residual value guarantees. Lease expense for minimum lease payments is recognized as rent expense on a straight-line basis over the lease term. Operating expenses such as common area maintenance and utilities are treated as variable lease payments.
|
Stock-Based Compensation |
Stock-Based Compensation Stock-based compensation expense is comprised of stock options awarded to employees and consultants. The Company accounts for share-based awards under the fair value method prescribed by ASC 718-10, Stock Compensation. The fair value of stock options is estimated using the Black-Scholes option pricing model on the date of grant. This option pricing model involves a number of estimates, including the per share value of the underlying common stock, exercise price, estimate of future volatility, expected term of the stock option award, risk-free interest rate and expected annual dividend yield. The fair value of the shares of common stock underlying the stock options has historically been determined by the Company’s board of directors as there was no public market for the underlying common stock prior to October 2, 2023. The Company’s board of directors determines the fair value of the Company’s common stock by considering a number of objective and subjective factors including contemporaneous third-party valuations of its common stock, the valuation of comparable companies, sales of the Company’s common stock to outside investors in arms-length transactions, the Company’s operating and financial performance, the lack of marketability, and general and industry specific economic outlook, and the implied fair values upon a merger transaction, amongst other factors. The Company recognizes the expense for options with graded-vesting schedules on a straight-line basis over the requisite service period, which is generally the vesting period. Forfeitures are recognized as they occur.
|
Basic and Diluted Net Loss Per Common Share |
Basic and Diluted Net Loss Per Common Share Basic net loss per common share is computed by dividing net loss for the year by the weighted-average number of common shares outstanding during the year. Diluted net loss per share is computed by dividing the net loss by the weighted-average number of common shares outstanding and potentially dilutive securities outstanding for the period using the treasury stock or if-converted method if their inclusion is dilutive. Diluted net loss per common share is the same as basic net loss per common share because the inclusion of potentially dilutive shares would be anti-dilutive to the calculation of net loss per common share. The Company has one class of shares issued and outstanding. Accordingly, basic and diluted net loss per share is not allocated among multiple classes of shares. Basic and diluted net loss per share for all periods prior to the Closing have been retrospectively adjusted by the Exchange Ratio to affect the reverse recapitalization. Potentially anti-dilutive shares excluded from the calculation of diluted net loss per share for three months ended March 31, 2024 include the following: | | | | | | Private warrants | 4,721,533 | Working capital warrants | 523,140 | Public warrants | 3,432,286 | PIPE warrants | 10,209,994 | Stock options | 1,969,261 | SPA warrants | 1,000,000 | Senior convertible notes’ shares | 1,000,000 | Deferred founder shares (1) | 1,173,631 | Convertible bridge loan warrants | 1,250,000 | Convertible bridge loan consideration shares | 7,334 | Convertible bridge loans | 619,146 | Convertible 12% promissory note warrants | 660,000 | Convertible 12% promissory notes | 367,850 | Total | 26,934,175 |
(1)As described in Note 8, Related Party Transactions, deferred founder shares do not have voting rights, do not participate in dividends and are not transferrable absent the Company’s consent. Therefore, while deferred founder shares are considered outstanding for legal purposes and are included in the total quantity of outstanding shares on the unaudited condensed consolidated statements of stockholders’ deficit, they are not considered outstanding for accounting purposes, including basic and diluted net loss per share purposes.
|
Recently Issued Accounting Pronouncements Not Yet Adopted |
Recently Issued Accounting Pronouncements Not Yet Adopted In December 2023, the FASB issued ASU No. 2023-09, Improvements to Income Tax Disclosures (Topic 740). The ASU requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as additional information on income taxes paid. The ASU is effective on a prospective basis for annual periods beginning after December 15, 2024. Early adoption is also permitted for annual financial statements that have not yet been issued or made available for issuance. This ASU will result in the required additional disclosures being included in the Company's unaudited condensed consolidated financial statements, once adopted. The Company is currently evaluating the impact of this standard on its financial statements and related disclosures.

At Closing, a cash payment of $1.3 million was disbursed to this vendor. The remaining $2.7 million amount was recognized as a component of the unpaid transaction costs assumed from Graf, of which $0.7 million represents a cash settlement obligation, and the remaining $2.0 million represents an obligation to issue a variable number of shares for a fixed monetary amount which was accounted for as a liability under ASC 480, Distinguishing Liabilities from Equity (“ASC 480”). Under ASC 480, the obligation to issue shares is not subsequently measured at fair value with changes recorded in earnings because the monetary amount is fixed. (2)Represents allocated fair value.

- DefinitionTabular disclosure of liabilities, including [financial] instruments measured at fair value that are classified in stockholders' equity, if any, by class that are measured at fair value on a recurring basis. The disclosures contemplated herein include the fair value measurements at the reporting date by the level within the fair value hierarchy in which the fair value measurements in their entirety fall, segregating fair value measurements using quoted prices in active markets for identical assets (Level 1), significant other observable inputs (Level 2), and significant unobservable inputs (Level 3). Where the quoted price in an active market for the identical liability is not available, the Level 1 input is the quoted price of an identical liability when traded as an asset.

- DefinitionThe estimated measure of the percentage by which a share price is expected to fluctuate during a period. Volatility also may be defined as a probability-weighted measure of the dispersion of returns about the mean. The volatility of a share price is the standard deviation of the continuously compounded rates of return on the share over a specified period. That is the same as the standard deviation of the differences in the natural logarithms of the stock prices plus dividends, if any, over the period.
