Corbus Pharmaceuticals Holdings, Inc.

Notes to Unaudited Condensed Consolidated Financial Statements

June 30, 2024

1. NATURE OF BUSINESS AND BASIS OF PRESENTATION

Nature of Business

Corbus Pharmaceuticals Holdings, Inc. (the "Company" or "Corbus") is a precision oncology company with a diversified portfolio and is committed to helping people defeat serious illness by bringing innovative scientific approaches to well-understood biological pathways. Corbus’ pipeline is comprised of two experimental drugs targeting solid tumors: CRB-701, a next-generation antibody drug conjugate ("ADC") that targets the expression of Nectin-4 on cancer cells to release a cytotoxic payload and CRB-601, an anti-integrin monoclonal antibody that blocks the activation of TGFβ expressed on cancer cells. The pipeline also includes CRB-913, a highly peripherally restricted cannabinoid type-1 ("CB1") receptor inverse agonist for the treatment of obesity. Since its inception, the Company has devoted substantially all of its efforts to business planning, research and development, recruiting management and technical staff, acquiring operating assets and raising capital. The Company’s business is subject to significant risks and uncertainties and the Company will be dependent on raising substantial additional capital before it becomes profitable, and it may never achieve profitability.

Basis of Presentation

The accompanying unaudited financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP") for interim financial reporting. In the opinion of management of the Company, the accompanying unaudited condensed consolidated interim financial statements reflect all adjustments (which include only normal recurring adjustments) necessary to present fairly, in all material respects, the condensed consolidated financial position of the Company as of June 30, 2024 and the results of its operations and changes in stockholders’ equity for the three and six months ended June 30, 2024 and 2023 and its cash flows for the six months ended June 30, 2024 and 2023. The December 31, 2023 condensed consolidated balance sheet was derived from audited financial statements. The Company prepared the condensed consolidated financial statements following the requirements of the U.S. Securities and Exchange Commission (the “SEC”) for interim reporting. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. It is suggested that these condensed consolidated financial statements be read in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, filed on March 12, 2024 (the “2023 Annual Report”). The results of operations for such interim periods are not necessarily indicative of the operating results for the full fiscal year.

Basis of Consolidation

The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany transactions and accounts have been eliminated in consolidation.

The significant accounting policies used in preparation of these condensed consolidated financial statements in this Form 10-Q are consistent with those discussed in Note 3, “Significant Accounting Policies,” in our 2023 Annual Report.

2. LIQUIDITY

The accompanying condensed consolidated financial statements have been prepared assuming the Company will continue as a going concern, which contemplates continuity of operations, realization of assets and the satisfaction of liabilities and commitments in the normal course of business. The Company has incurred recurring losses since inception and as of June 30, 2024, had an accumulated deficit of approximately $453.6 million. The Company anticipates operating losses to continue for the foreseeable future due to, among other things, costs related to research funding, development of its product candidates and its pre-clinical and clinical programs, strategic alliances, and the development of its administrative organization. The Company expects that its cash, cash equivalents, and investments of approximately $147.0 million at June 30, 2024 will be sufficient to meet its operating and capital requirements at least twelve months from the issuance of this Quarterly Report on Form 10-Q.

-8-

The source, timing and availability of any future financing will depend principally upon market conditions, and, more specifically, on the progress of the Company’s clinical development programs. Funding may not be available when needed, at all, or on terms acceptable to the Company. Lack of necessary funds may require the Company to, among other things, delay, scale back or eliminate some or all of the Company’s planned clinical or pre-clinical trials. Refer to Note 12 for additional information related to the Company's recent financings.

3. CASH, CASH EQUIVALENTS, AND RESTRICTED CASH

The Company considers only those investments which are highly liquid, readily convertible to cash, and that mature within 90 days from the date of purchase to be cash equivalents. At June 30, 2024 and December 31, 2023, cash equivalents were comprised of money market funds and corporate debt securities with maturities less than 90 days from the date of purchase.

Restricted cash as of June 30, 2024 included security for a stand-by letter of credit issued in favor of a landlord for $0.7 million of which $0.3 million was classified in current assets and $0.4 million was classified in noncurrent assets as of June 30, 2024.

Cash, cash equivalents, and restricted cash consist of the following (in thousands):


	June 30, 2024		December 31, 2023
Cash	$	4,502	$	4,029
Cash equivalents		19,184		9,695
Cash and cash equivalents		23,686		13,724

Restricted cash, current		285		192
Restricted cash, noncurrent		385		478
Restricted cash		670		670
Total cash, cash equivalents, and restricted cash shown in the statement of cash flows	$	24,356	$	14,394

As of June 30, 2024, the Company’s cash and cash equivalents held in the U.S. was approximately $19.4 million and approximately $4.3 million of cash was held in its subsidiaries in the United Kingdom and Australia. As of December 31, 2023, all of the Company’s cash was held in the U.S., except for approximately $3.8 million of cash which was held in its subsidiaries in the United Kingdom and Australia.

Our foreign subsidiaries in the United Kingdom and Australia may qualify for refundable research and development tax credits in the form of cash that were earned on certain research and development expenses incurred primarily outside of the U.S. The Company received no refundable research and development credits from foreign tax authorities for the three months ended June 30, 2024 and 2023 and $2.5 million for the six months ended June 30, 2024 recorded in other income (expense), net. No future conditions impact the recognition of these tax credits.

The Company entered into a license agreement (the “Jenrin License Agreement”) with Jenrin Discovery, LLC ("Jenrin"), a privately-held Delaware limited liability company, effective September 20, 2018. Pursuant to the Jenrin License Agreement, Jenrin granted the Company exclusive worldwide rights to develop and commercialize the Licensed Products (as defined in the Jenrin Agreement) which includes the Jenrin library of over 600 compounds and multiple issued and pending patent filings. The compounds are designed to treat inflammatory and fibrotic diseases by targeting the endocannabinoid system.

In consideration of the license and other rights granted by Jenrin, the Company paid Jenrin a $0.3 million upfront cash payment and is obligated to pay potential milestone payments to Jenrin totaling up to $18.4 million for each compound it elects to develop based upon the achievement of specified development and regulatory milestones.

The Company entered into a license agreement (the “Milky Way License Agreement”) with Milky Way BioPharma, LLC (“Milky Way”), a subsidiary of Panorama Research Inc., effective May 25, 2021. Pursuant to the Milky Way License Agreement, the Company received an exclusive license, under certain patent rights and know-how owned or controlled by Milky Way, to develop, commercialize, and otherwise exploit products containing antibodies against integrin αvβ6 and/or integrin αvβ8 (“Licensed Products”), one of which the Company is referring to as CRB-602. Under the terms of the Milky Way License Agreement, the Company had sole responsibility for research, development, and commercialization of any Licensed Products, and the Company had agreed to use commercially reasonable efforts to perform these activities. The Milky Way Agreement may be terminated earlier in specified situations, including termination for material breach or termination by the Company with advance notice. A notice of termination without reason was executed by the Company and sent to Milky Way on January 25, 2024, terminating the Milky Way Agreement effective as of July 23, 2024.

The Company entered into a license agreement (the “UCSF License Agreement”) with the Regents of the University of California (“The Regents”) effective May 26, 2021. Pursuant to the UCSF License Agreement, the Company received an exclusive license to certain patents relating to humanized antibodies against integrin αvβ8, one of which the Company is referring to as CRB-601, along with non-exclusive licenses to certain related know-how and materials. The Company amended the UCSF License Agreement with The Regents effective November 17, 2022 adding additional antibody patents to the agreement.

In consideration for the license and other rights granted to the Company under the UCSF License Agreement, the Company paid The Regents a license issue fee of $1.5 million. In consideration for the additional antibody patents granted to the Company, the Company paid The Regents a license issue fee of $0.8 million, paid in two equal installments of $0.4 million.

The Company further amended the UCSF License Agreement with The Regents effective August 14, 2023 to incorporate certain new technology rights and amend the payment schedule for the development milestone for the filing of patent rights and the development milestone for the filing of an Investigational New Drug ("IND").

In addition to the license issuance fees, the Company is obligated to pay an annual license maintenance fee, as well as up to $153.2 million in potential milestone payments, excluding indication milestones for antibodies used for diagnostic products

and services that will be an additional $50.0 thousand for each new indication, for the achievement of certain development, regulatory, and sales milestones. In addition, the Company is also obligated to pay royalties in the lower, single digits on sales of products falling within the scope of the licensed patents, which is subject to a minimum annual royalty obligation, and a percentage share of certain payments received by the Company from sublicensees or in connection with the sale of the licensed program.

The Company entered into a license agreement (the “CSPC License Agreement”) with CSPC Megalith Biopharmaceutical Co., Ltd. ("CSPC"), a subsidiary of CSPC Pharmaceutical Group Limited, effective February 12, 2023. Pursuant to the CSPC License Agreement, the Company received an exclusive license to develop and commercialize a novel clinical stage antibody drug conjugate targeting Nectin-4, which the Company is referring to as CRB-701, in the U.S., Canada, the European Union (including the European Free Trade Area), the United Kingdom, and Australia.

In consideration for the license granted to the Company under the CSPC License Agreement, the Company will pay CSPC an upfront payment of $7.5 million ($5.0 million paid at signing during the first quarter 2023 followed by a $2.5 million payment due in August 2024). The Company is obligated to pay potential milestone payments to CSPC totaling up to $130.0 million based upon the achievement of specified development and regulatory milestones and $555.0 million in potential commercial milestone payments. In addition, we are obligated to pay royalties in the low double digits based on net sales of any Licensed Products, as defined in the CSPC License Agreement.

The Company determined that substantially all of the fair value of the Jenrin License Agreement and CSPC License Agreement was attributable to a single in-process research and development asset which did not constitute a business. The Company determined that substantially all of the fair value of the Milky Way License Agreement and the UCSF License Agreement was attributable to separate groups of in-process research and development assets which did not constitute a business. The Company concluded that it did not have any alternative future use for the acquired in-process research and development assets. Thus, the Company recorded the various upfront payments to research and development expenses in the quarter the license deals became effective. The Company will account for the development, regulatory, and sales milestone payments in the period that the relevant milestones are achieved as either research and development expense or as an intangible asset as applicable. As of June 30, 2024, the Company has accrued license costs of $4.1 million included within accrued expenses on the condensed consolidated balance sheet related to the remaining $2.5 million due to CSPC under the CSPC License Agreement for an upfront license payment and $1.6 million due to The Regents under the UCSF License Agreement for achieved milestone payments (due on December 30, 2024 based upon the amended payment schedule). For the three and six months ended June 30, 2024, no research and development expense associated with upfront payments or clinical milestones were incurred under any of the above agreements. Research and development expenses associated with upfront payments and clinical milestones were $0 and $9.1 million, respectively, for the three and six months ended June 30, 2023.

Loan and Security Agreement with K2 HealthVentures LLC

On July 28, 2020, the Company, with its subsidiary, Corbus Pharmaceuticals, Inc., as borrower, entered into a secured Loan and Security Agreement with K2 HealthVentures LLC (“K2HV”), an unrelated third party (the “Loan and Security Agreement”) and received $20.0 million upon signing. The Company entered into an Amendment to the Loan and Security Agreement (the "Amended Loan and Security Agreement") on October 25, 2022. Interest payments are made monthly and accrue at a variable annual rate equal to the greater of (i) 8.5% and (ii) the rate of interest noted in The Wall Street Journal, Money Rates section, as the “Prime Rate” plus 5.25%, in each case, subject to a step-down of 25 basis points upon the funding of the second tranche. The interest rate used at June 30, 2024 was 13.75%.

Pursuant to the Amended Loan and Security Agreement, K2HV may elect to convert up to $5.0 million of the outstanding loan balance into shares of the Company’s common stock at conversion prices as follows: $0.9 million of the loan at $4.50 per share, $1.1 million at $7.875 per share, and $3.0 million at $282.00 per share. On June 1, 2023, K2HV converted $0.9 million of the outstanding loan balance into 194,444 shares of the Company's stock at a conversion price of $4.50 per share. On March 6, 2024, K2HV converted $1.1 million of the outstanding loan balance into 142,857 shares of the Company's stock at a conversion price of $7.875 per share.

The K2 Warrant may be exercised either for cash or on a cashless “net exercise” basis and expires on July 28, 2030.

-13-

The Company is required to make a final payment in excess of the stated principal equal to $1.6 million at the end of the loan. This payment has been amortized over the life of the loan through interest expense, net within the condensed consolidated statements of operations and comprehensive loss and is included in accrued expense on the condensed consolidated balance sheet as of June 30, 2024.

The Loan and Security Agreement includes both financial and non-financial covenants. The Company was in compliance with these covenants as of June 30, 2024. The obligations under the Loan and Security Agreement are secured on a senior basis by a lien on substantially all of the assets of the Company and its subsidiaries. The subsidiaries of the Company are guarantors of the obligations of the Company under the Loan and Security Agreement.

The total debt discount related to the Amended Loan and Security Agreement of approximately $3.0 million is being charged to interest expense using the effective interest method over the term of the debt. At June 30, 2024 and December 31, 2023, the fair value of our outstanding debt, which is considered level 3 in the fair value hierarchy, approximates carrying value. Interest expense for the three and six months ended June 30, 2024 was approximately $0.6 million and $1.5 million, respectively. Interest expense for the three and six months ended June 30, 2023 was $1.0 million and $1.9 million, respectively.

13. STOCK-BASED COMPENSATION AWARDS

On May 16, 2024, the Company's stockholders approved the 2024 Equity Compensation Plan (the “2024 Plan”) authorizing the issuance of up to 2,000,000 shares, succeeding the 2014 Equity Incentive Plan (the “2014 Plan”), under which no further grants may be made pursuant to the terms of the 2014 Plan.

Total stock-based compensation	$	1,288	$	823	$	2,270	$	1,850

Stock Options

The fair value of each stock option award is estimated on the date of grant using the Black-Scholes stock option pricing model that uses the assumptions noted in the following table, except for the expected term for non-employees as noted in the following paragraph. The expected term of employee and non-employee director stock options granted under the 2014 Plan and 2024 Plan, all of which qualify as “plain vanilla” per SEC Staff Accounting Bulletin 107, is determined based on the simplified method due to the Company’s limited operating history. The expected term is applied to the stock option grant group as a whole, as the Company does not expect substantially different exercise or post-vesting termination behavior among our employee population. For non-employee stock options, excluding directors, the Company has elected to utilize the contractual term as the expected term. The risk-free rate is based on the yield of a U.S. Treasury security with a term consistent with that used to value the stock option. The Company accounts for forfeitures as they occur.

The weighted average assumptions used principally in determining the fair value of stock options granted to employees and non-employee directors were as follows:


	Six Months Ended June 30,
	2024			2023
Risk-free interest rate		4.25	%		3.81	%
Expected dividend yield		0	%	0%
Expected term in years (employee options)		6.19		6.25
Expected volatility		124.31	%		101.33	%

A summary of stock option activity for the six months ended June 30, 2024 is presented below:


Stock Options	Shares			Weighted Average Exercise Price		Weighted Average Remaining Contractual Term in Years		Aggregate Intrinsic Value (in thousands)
Outstanding at December 31, 2023		708,762		$	63.96
Granted		236,850			27.22

The weighted average grant date fair value of stock options granted during the six months ended June 30, 2024 and 2023 was $24.30 and $4.20 per share, respectively. The aggregate intrinsic value of stock options exercised during the six months ended June 30, 2024 and 2023 was approximately $4.1 million and $0.1 million, respectively. As of June 30, 2024, there was approximately $6.7 million of total unrecognized compensation expense, related to non-vested share-based stock option compensation arrangements. The unrecognized compensation expense is estimated to be recognized over a weighted average period of 1.53 years as of June 30, 2024.

Restricted Stock Units

A RSU represents the right to receive one share of our common stock upon vesting of the RSU. The fair value of each RSU is based on the closing price of our common stock on the date of grant. The Company accounts for forfeitures as they occur.

A summary of RSU activity for the six months ended June 30, 2024 is presented below:


RSU's	Number of Shares Underlying RSUs			Weighted Average Grant Date Fair Value
Unvested at December 31, 2023		17,911		$	5.14
Granted		236,854		$	26.85
Forfeited		(2,193	)	$	17.15
Vested		(3,764	)	$	4.89
Unvested at June 30, 2024		248,808		$	25.71

15. DERIVATIVE LIABILITY

On July 28, 2020, the Company, with its subsidiary, Corbus Pharmaceuticals, Inc., as borrower, entered into the secured Loan and Security Agreement with K2HV and received $20.0 million upon signing. The Company has determined that a prepayment feature and default feature needed to be separately valued and marked to market each reporting period after assessing the agreement under ASC 815.

The value of these features is determined each reporting period by taking the present value of net cash flows with and without the prepayment features. The significant assumption used to determine the fair value of the debt without any features is the

-18-

discount rate which has been estimated by using published market rates of CCC-rated public companies. All other inputs are taken from the Loan and Security Agreement. The additional significant assumptions used when valuing the prepayment feature is the probability of a change of control event. The Company has determined the probability from December 31, 2023 to June 30, 2024 has decreased from 10% to 0%. The additional significant assumption used when valuing the default feature is the probability of defaulting on the repayment of the loan. The Company has determined the probability from December 31, 2023 to June 30, 2024 has decreased from 55% to 0%. The value of these features was determined to be $0 at June 30, 2024, which resulted in income of $39.0 thousand recognized in the six months ended June 30, 2024. The Company considers the fair value of the derivative liability to be Level 3 under the three-tier fair value hierarchy.

A roll forward of the fair value of the derivative liabilities for the six months ended June 30, 2024 is presented below (in thousands).

Overview

Corbus Pharmaceuticals Holdings, Inc. (the “Company,” “Corbus,” “we,” “us,” or “our”) is a precision oncology company with a diversified portfolio and is committed to helping people defeat serious illness by bringing innovative scientific approaches to well-understood biological pathways. Our pipeline is comprised of two experimental drugs targeting solid tumors: CRB-701, a next-generation antibody drug conjugate (“ADC”) that targets the expression of Nectin-4 on cancer cells to release a cytotoxic payload; and CRB-601, an anti-integrin monoclonal antibody that blocks the activation of TGFβ expressed on cancer cells. The pipeline also includes CRB-913, a highly peripherally restricted cannabinoid type-1 (“CB1”) receptor inverse agonist for the treatment of obesity.

Our oncology pipeline:

•

CRB-701 is a next-generation ADC targeting the expression of Nectin-4 on cancer cells to release a cytotoxic payload. In February 2023, we obtained a license from CSPC Megalith Biopharmaceutical Co. Ltd. (“CSPC”), a subsidiary of CSPC Pharmaceutical Group Limited, to develop and commercialize the drug in the United States ("U.S."), Canada, the European Union (including the European Free Trade Area), the United Kingdom and Australia (the “CSPC License Agreement”). The Investigational New Drug (“IND”) application for CRB-701 was cleared by the U.S. Food and Drug Administration (“FDA”) in 2022 and the drug is currently being investigated by CSPC in a Phase 1 dose-escalation clinical trial in patients with advanced solid tumors in China. On June 1, 2024, updated clinical data was presented at ASCO 2024 by CSPC building upon the data presented at ASCO-GU on January 26, 2024. The larger data set included 37 patients of whom 25 patients reflective of seven dose levels had been evaluated for efficacy at the time of the data cut. The emerging clinical data shows that CRB-701 was well-tolerated and demonstrated an overall response rate ("ORR") of 44% and a disease control rate ("DCR") of 78% in metastatic urothelial cancer ("mUC") and 43% ORR and 86% DCR in cervical cancer. No dose limiting toxicities (“DLTs”) have been observed to date in doses up to and including 4.5 mg/Kg. On April 2, 2024, the first patient in the U.S. Phase 1 clinical trial was dosed. The study is currently enrolling patients with mUC and other Nectin-4 enriched tumors.

•

CRB-601 is a potent and selective anti-αvβ8 monoclonal antibody that blocks the activation of latent TGFβ found on cancer cells. In pre-clinical models, CRB-601 demonstrates enhanced anti-tumor activity when combined with an anti-PD-1 checkpoint inhibitor compared to each single agent on its own. The data suggests that blockade of latent TGFβ production by CRB-601 can lead to changes in immune cell infiltration in the tumor microenvironment, thus potentially enhancing the benefit of PD-1 blockade. CRB-601 is being developed as a potential treatment for patients with solid tumors in combination with existing therapies, including checkpoint inhibitors. On January 9, 2024, we announced that the FDA cleared the IND for CRB-601 and we expect to enroll the first patient in a Phase 1 study in Q4 2024.

Our obesity pipeline:

•

CRB-913 is a second-generation highly peripherally restricted CB1 receptor inverse agonist designed to treat obesity. In a diet-induced obesity (“DIO”) mouse model, CRB-913 demonstrates a reduction in body weight, body fat content, leptinemia, insulin resistance, liver triglycerides, liver fat deposits, and improvements in liver histology. These outcomes were further improved when CRB-913 was used in combination with incretin analogs (tirzepatide, semaglutide, or liraglutide). We are currently conducting IND-enabling studies and we expect to treat the first patient in a Phase 1 study in the first quarter of 2025.

Recent Developments

Open Market Sale Agreement

On May 31, 2023, the Company entered into the Open Market Sale Agreement with Jefferies, as sales agent. Under the Open Market Sale Agreement, the Company may issue and sell, from time to time through Jefferies, shares of its common stock having an aggregate offering price of up to $150.0 million. During the three and six months ended June 30, 2024, the Company sold an aggregate of 881,399 and 1,820,787 shares of common stock, respectively, under the Open Market Sale Agreement, for net proceeds of approximately $35.6 million and $55.8 million, respectively. As of June 30, 2024, approximately $113.2 million was available for issuance and sale under the Open Market Sale Agreement.

Financial Operations Overview

We are a precision oncology company and have not generated any revenues from the sale of products. We do not expect to generate revenue from product sales unless and until we successfully complete development and obtain regulatory approval for the marketing of one of our product candidates, which we expect will take a number of years and is subject to significant uncertainty. We have never been profitable and at June 30, 2024, we had an accumulated deficit of approximately $453.6 million. Our net losses for the three months ended June 30, 2024 and 2023, were approximately $10.0 million and $8.8 million, respectively. For the six months ended June 30, 2024 and 2023, our net losses were approximately $16.9 million and $26.5 million, respectively.

We expect to continue to incur significant expenses for the foreseeable future. We expect our expenses to increase in 2024 as compared to 2023 as we incur Phase 1 clinical trial costs for both CRB-701 and CRB-601. We will continue to incur significant operating losses as we move into the clinical phase and, accordingly, we will need additional financing to support our continuing operations. We will seek to fund our operations through public or private equity, debt financings or other sources, which may include government grants and collaborations with third parties. Adequate additional financing may not be available to us on acceptable terms, or at all. Our failure to raise capital as and when needed would have a negative impact on our financial condition and our ability to pursue our business strategy. We will need to generate significant revenues to achieve profitability, and we may never do so.

We expect to continue to incur operating losses for at least the next several years in connection with our ongoing activities, as we:

•

conduct pre-clinical and clinical trials for our product candidates;

•

continue our research and development efforts; and

•

manufacture and purchase drugs for clinical studies.

Critical Accounting Policies and Estimates

Our condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the U.S. The preparation of these financial statements requires management to make estimates, assumptions, and judgments that affect the reported amounts of assets, liabilities, revenue, costs of expenses and related disclosures in the condensed consolidated financial statements. On an ongoing basis, we evaluate our estimates and judgments. We base our estimates and judgments on historical experience, current economic and industry conditions and on various other factors that are believed to be reasonable under the circumstances. This forms the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

There have been no changes to the critical accounting estimates we identified in "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" in our 2023 Annual Report.

Results of Operations

Comparison of Three Months Ended June 30, 2024 and 2023

Research and Development. Research and development expenses for the three months ended June 30, 2024 totaled approximately $6.9 million, an increase of $2.7 million from approximately $4.2 million recorded for the three months ended June 30, 2023. The increase in fiscal quarter 2024 as compared to 2023 was primarily attributable to increases of $2.0 million in CRB-701 clinical trial costs with our contract research organizations ("CROs") and clinical sites, as well as $0.3 million in drug manufacturing costs for CRB-913 and $0.2 million in higher stock-based compensation costs as stock options are being granted at higher current fair values as compared to earlier grants. These increases are offset by a $0.5 million decrease in toxicology costs as we transition from pre-clinical to clinical phase for CRB-601.

The Company has a subsidiary in each of the United Kingdom and Australia and approximately 35% and 46% of research and development expenses recorded for the three months ended June 30, 2024 and 2023, respectively was recorded in these entities.

General and Administrative. General and administrative expenses for the three months ended June 30, 2024 totaled approximately $4.1 million, an increase of $0.2 million from approximately $3.9 million recorded for the three months ended June 30, 2023. The expense in fiscal 2024 as compared to fiscal 2023 is comparable.

-22-

Other Income (Expense), Net. Other income (expense), net for the three months ended June 30, 2024 was approximately $1.0 million in income as compared to other expense of approximately $0.6 million recorded for the three months ended June 30, 2023. The increase of $1.6 million in 2024 as compared to 2023 was primarily attributable to higher investment income due to higher cash and investment balances and reduced interest expense as principal payments were made on debt in 2024.

Comparison of Six Months Ended June 30, 2024 and 2023

Research and Development. Research and development expenses for the six months ended June 30, 2024 totaled approximately $12.6 million, a decrease of $5.0 million from approximately $17.6 million recorded for the six months ended June 30, 2023. The decrease in fiscal 2024 as compared to fiscal 2023 was primarily attributable to decreases in licensing costs of $7.5 million associated with the CSPC License Agreement and $1.2 million associated with the achievement of a development milestone under the UCSF License Agreement. This decrease is offset by increases of $3.2 million in CRB-701 clinical trial costs with our contract research organizations ("CROs") and clinical sites, as well as $0.9 million in drug manufacturing costs, primarily related to CRB-701 drug purchases, packaging, labeling, and distribution to clinical trial sites.

The Company has a subsidiary in each of the United Kingdom and Australia and approximately 33% and 20% of research and development expenses recorded for the six months ended June 30, 2024 and 2023, respectively was recorded in these entities.

General and Administrative. General and administrative expenses for the six months ended June 30, 2024 totaled approximately $8.0 million, an increase of $0.2 million from approximately $7.8 million recorded for the six months ended June 30, 2023. The expense in fiscal 2024 as compared to fiscal 2023 is comparable. The $0.2 million increase is primarily due to an increase in legal costs and franchise taxes, partially offset by a decrease in personnel related costs associated with prior period reductions in headcount.

Other Income (Expense), Net. Other income (expense), net for the six months ended June 30, 2024 was approximately $3.7 million in income as compared to other expense of approximately $1.0 million recorded for the six months ended June 30, 2023. The increase of $4.7 million in 2024 as compared to 2023 was primarily attributable to receipt of refundable research and development credits from a foreign tax authority of approximately $2.5 million in 2024, as well as higher investment income due to higher cash and investment balances and reduced interest expense as principal payments were made on debt in 2024.

Liquidity and Capital Resources

Since inception, we have experienced negative cash flows from operations. We have financed our operations primarily through sales of equity-related securities. At June 30, 2024, our accumulated deficit since inception was approximately $453.6 million.

At June 30, 2024, we had total current assets of approximately $148.3 million and current liabilities of approximately $24.0 million, resulting in working capital of approximately $124.3 million. Of our total cash, cash equivalents, investments, and restricted cash of $147.7 million at June 30, 2024, approximately $143.4 million was held within the U.S.

Net cash used in operating activities for the six months ended June 30, 2024 was approximately $16.9 million, which includes a net loss of approximately $16.9 million, adjusted for non-cash expenses of approximately $1.0 million largely related to stock-based compensation expense offset by net amortization on discount of investments, and approximately $1.0 million of cash used in net working capital items principally due to decreases in accounts payable and operating lease liabilities offset by a decrease in prepaid expenses and other current assets.

Cash used by investing activities for the six months ended June 30, 2024 totaled approximately $114.7 million, which was principally related to purchases of marketable securities.

Cash provided by financing activities for the six months ended June 30, 2024 totaled approximately $141.5 million, which was related to the issuance of common stock. On January 31, 2024, we entered into an underwriting agreement with Jefferies, as representative of the underwriters, relating to an underwritten public offering of 4,325,000 shares of our common stock at a price to the public of $19.00 per share. The underwriters were also granted a 30-day option to purchase up to an additional 648,750 shares of common stock at the public offering price. On January 31, 2024, Jefferies gave notice of the underwriters’ election to exercise the option to purchase additional shares, in full. On February 2, 2024, we completed the public offering raising gross proceeds of approximately $94.5 million and net proceeds of $88.6 million, after deducting underwriting discounts and commissions and other offering expenses payable by us. In addition, for the six months ended June 30, 2024, we sold an aggregate of 1,820,787 shares of common stock under the Open Market Sale Agreement, for net proceeds of approximately $55.8 million.

-23-

We expect our cash, cash equivalents, and investments of approximately $147.0 million at June 30, 2024 will be sufficient to meet our operating and capital requirements to support our operations through the third quarter of 2027, based on current planned expenditures.

We will need to raise significant additional capital to continue to fund the clinical trials for CRB-701 and CRB-601. We may seek to sell common or preferred equity or convertible debt securities, enter into a credit facility or another form of third-party funding or seek other debt financing. In addition, we may seek to raise cash through collaborative agreements or from government grants. The sale of equity and convertible debt securities may result in dilution to our stockholders and certain of those securities may have rights senior to those of our common shares. If we raise additional funds through the issuance of preferred stock, convertible debt securities or other debt financing, these securities or other debt could contain covenants that would restrict our operations. Any other third-party funding arrangement could require us to relinquish valuable rights.

The source, timing and availability of any future financing will depend principally upon market conditions, and, more specifically, on the progress of our clinical development programs. Funding may not be available when needed, at all, or on terms acceptable to us. Lack of necessary funds may require us, among other things, to delay, scale back or eliminate expenses including some or all of our planned clinical trials.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that is material to investors, other than future royalty payments under license agreements discussed as follows:

PART II — OTHER INFORMATION

Item 1. Legal Proceedings.

We are not currently subject to any material legal proceedings. However, we may from time to time become a party to various legal proceedings arising in the ordinary course of our business.

Item 1A. Risk Factors.

Except as set forth below, there have been no material changes in or additions to the risk factors included in our Annual Report on Form 10-K for the year ended December 31, 2023.

We are, and will be, completely dependent on third parties to manufacture our drug candidates, and our commercialization of our drug candidates could be halted, delayed or made less profitable if those third parties fail to obtain manufacturing approval from the FDA or comparable foreign regulatory authorities, fail to provide us with sufficient quantities of our drug candidates or fail to do so at acceptable quality levels or prices.

We do not currently have, nor do we plan to acquire, the capability or infrastructure to manufacture the active pharmaceutical ingredients of our drug candidates, or the finished drug products, for use in our clinical trials or for commercial product, if any. As a result, we will be obligated to rely on contract manufacturers if and when our drug candidates are approved for commercialization.

We currently rely on contract suppliers for the manufacturing of our drug candidates. We have limited experience contracting third parties to manufacture our drug candidates and we do not control the manufacturing processes of, and are completely dependent on, our contract manufacturing partners for compliance with current good manufacturing practices ("cGMPs") for manufacture of all active drug substances and finished drug products. These cGMP regulations cover all aspects of the manufacturing, testing, quality control and record keeping relating to our drug candidates. If our contract manufacturers cannot successfully manufacture material that conforms to our specifications and the strict regulatory requirements of the FDA or others, they will not be able to secure and/or maintain regulatory approval for their manufacturing facilities. If the FDA or a comparable foreign regulatory authority does not approve these facilities for the manufacture of our product candidates or if it withdraws any such approval in the future, we may need to find alternative manufacturing facilities, which would significantly impact our ability to develop, obtain regulatory approval for or market our drug candidates, if approved.

Our contract manufacturers will be subject to ongoing periodic unannounced inspections by the FDA and corresponding state and foreign agencies for compliance with cGMPs and similar regulatory requirements. We will not have control over our contract manufacturers’ compliance with these regulations and standards. Failure by any of our contract manufacturers to comply with applicable regulations could result in sanctions being imposed on us, including fines, injunctions, civil penalties, failure to grant approval to market our drug candidates, delays, suspensions or withdrawals of approvals, operating restrictions and criminal prosecutions, any of which could significantly and adversely affect our business. In addition, we will not have control over the ability of our contract manufacturers to maintain adequate quality control, quality assurance and qualified personnel. Failure by our contract manufacturers to comply with or maintain any of these standards could adversely affect our ability to develop, obtain regulatory approval for or market our drug candidates.

If, for any reason, these third parties are unable or unwilling to perform, we may not be able to terminate our agreements with them, and we may not be able to locate alternative manufacturers or formulators or enter into favorable agreements with them and we cannot be certain that any such third parties will have the manufacturing capacity to meet future requirements. If these manufacturers or any alternate manufacturer of finished drug product experiences any significant difficulties in its respective manufacturing processes for our active pharmaceutical ingredient, or API, or our finished products or should cease doing business with us, we could experience significant interruptions in the supply of our drug candidates or may not be able to create a supply of our drug candidates at all. Were we to encounter manufacturing issues, our ability to produce a sufficient supply of our drug candidates might be negatively affected. Our inability to coordinate the efforts of our third-party manufacturing partners, or the lack of capacity available at our third-party manufacturing partners, could impair our ability to supply our drug candidates at required levels. Because of the significant regulatory requirements that we would need to satisfy in order to qualify a new bulk or finished product manufacturer, if we face these or other difficulties with our current manufacturing partners, we could experience significant interruptions in the supply of our drug candidates if we decided to transfer the manufacture of our drug candidates to one or more alternative manufacturers in an effort to deal with the difficulties.

-26-

In addition, we currently rely on foreign third parties to manufacture certain materials used in clinical trials of our product candidates or to provide services in connection with certain clinical trials and will likely continue to rely on foreign third parties in the future. Foreign third parties may be subject to U.S. legislation, including the proposed BIOSECURE bill, trade restrictions and other foreign regulatory requirements. Any manufacturing problem or the loss of a contract manufacturer could be disruptive to our operations and result in lost sales. Additionally, we rely on third parties to supply the raw materials needed to manufacture our potential products. Any reliance on suppliers may involve several risks, including a potential inability to obtain critical materials and reduced control over production costs, delivery schedules, reliability, and quality. Any unanticipated disruption to a future contract manufacturer caused by problems at suppliers could delay shipment of our drug candidates, increase our cost of goods sold and result in lost sales.

We cannot guarantee that our manufacturing and supply partners will be able to manufacture our drug candidates at commercial scale on a cost-effective basis. If the commercial-scale manufacturing costs of our drug candidates are higher than expected, these costs may significantly impact our operating results. In order to reduce costs, we may need to develop and implement process improvements. However, in order to do so, we will need, from time to time, to notify or make submissions with regulatory authorities, and the improvements may be subject to approval by such regulatory authorities. We cannot be sure that we will receive these necessary approvals or that these approvals will be granted in a timely fashion. We also cannot guarantee that we will be able to enhance and optimize output in our commercial manufacturing process. If we cannot enhance and optimize output, we may not be able to reduce our costs over time.

We expect that we will rely on third parties to assist us in conducting clinical trials for our drug candidates. If these third parties do not successfully carry out their contractual duties or meet expected deadlines, we may not be able to obtain regulatory approval for or commercialize our drug candidates and our business would be substantially harmed.

We expect to enter into agreements with third-party CROs to assist us in conducting and managing our clinical programs, including contracting with clinical sites to perform our clinical studies. We plan to rely on these parties for execution of clinical studies for our drug candidates and we will control only certain aspects of conducting the clinical studies. Nevertheless, we will be responsible for ensuring that each of our studies is conducted in accordance with the applicable protocol, legal, regulatory and scientific standards, and our reliance on CROs and clinical sites will not relieve us of our regulatory responsibilities. We and our CROs will be required to comply with cGCPs, which are regulations and guidelines enforced by the FDA, the Competent Authorities of the Member States of the European Economic Area and comparable foreign regulatory authorities for any products in clinical development. The FDA enforces these cGCP regulations through periodic inspections of trial sponsors, principal investigators and trial sites. If we or our CROs fail to comply with applicable cGCPs, the clinical data generated in our clinical trials may be deemed unreliable and the FDA or comparable foreign regulatory authorities may require us to perform additional clinical trials before approving our marketing applications. We cannot assure you that, upon inspection, the FDA will determine that any of our clinical trials comply with cGCPs. In addition, our clinical trials must be conducted with products produced under cGMP regulations and will require a large number of test subjects. Our failure or the failure of our CROs or clinical sites to comply with these regulations may require us to repeat clinical trials, which would delay the regulatory approval process and could also subject us to enforcement action up to and including civil and criminal penalties.

Although we intend to design the clinical trials for our drug candidates in consultation with CROs, we expect that the CROs will manage and assist us with the clinical trials conducted at contracted clinical sites. As a result, many important aspects of our drug development programs would be outside of our direct control. In addition, the CROs and clinical sites may not perform all of their obligations under arrangements with us or in compliance with regulatory requirements. If the CROs or clinical sites do not perform clinical trials in a satisfactory manner, or if they breach their obligations to us or fail to comply with regulatory requirements, the development and commercialization of our drug candidates for the subject indications may be delayed or our development program materially and irreversibly harmed. We cannot control the amount and timing of resources these CROs and clinical sites will devote to our program or our drug candidates. If we are unable to rely on clinical data collected by our CROs, we could be required to repeat, extend the duration of, or increase the size of our clinical trials, which could significantly delay commercialization and require significantly greater expenditures.

-27-

In addition, we currently rely on foreign CROs to manufacture certain materials used in clinical trials of our product candidates or to provide services in connection with certain clinical trials and will likely continue to rely on foreign CROs in the future. Foreign CROs may be subject to U.S. legislation, including the proposed BIOSECURE bill, trade restrictions and other foreign regulatory requirements. If any of our relationships with these third-party CROs or clinical sites terminate, we may not be able to enter into arrangements with alternative CROs or clinical sites. If CROs do not successfully carry out their contractual duties or obligations or meet expected deadlines, if they need to be replaced or if the quality or accuracy of the clinical data they obtain is compromised due to the failure to adhere to our clinical protocols, regulatory requirements or for other reasons, any such clinical trials may be extended, delayed or terminated, and we may not be able to obtain regulatory approval for or successfully commercialize our drug candidates. As a result, our financial results and the commercial prospects for our drug candidates would be harmed, our costs could increase and our ability to generate revenue could be delayed.

Changes in geopolitical conditions, U.S.-China trade relations and other factors beyond our control may adversely impact our business and operating results.

Our operations and performance depend, in part, on global and regional economic and geopolitical conditions, given our current third-party license agreement with CSPC, which is headquartered in China. Changes in U.S.-China trade policies, including the proposed BIOSECURE bill, and a number of other economic and geopolitical factors both in China and abroad could have a material adverse effect on our business, financial condition, results of operations or prospects. Such factors may include:

•

instability in political or economic conditions, such as inflation, recession, foreign currency exchange restrictions and devaluations, restrictive governmental controls on the movement and repatriation of earnings and capital, and actual or anticipated military or political conflicts, particularly in emerging markets;

•

expanded jurisdiction of the Committee for Foreign Investment in the U.S. (CFIUS); and

•

intergovernmental conflicts or actions, such as armed conflict, trade wars, retaliatory tariffs, and acts of terrorism or war.

As a result of these events, our ability to obtain data or regulatory support from our China-based licensing partner may be limited or adversely affected, and we may ourselves be subject to sanctions, diminished public perception and operational constraints.

Our product candidates may infringe the intellectual property rights of others, which could increase our costs and delay or prevent our development and commercialization efforts.

Our success depends in part on avoiding infringement of the proprietary technologies of others. The pharmaceutical industry has been characterized by frequent litigation regarding patent and other intellectual property rights. Identification of third-party patent rights that may be relevant to our proprietary technology is difficult because patent searching is imperfect due to differences in terminology among patents, incomplete databases, and the difficulty in assessing the meaning of patent claims. Additionally, because patent applications are maintained in secrecy until the application is published, we may be unaware of third-party patents that may be infringed by any of our product candidates. There may be certain issued patents and patent applications claiming subject matter that we may be required to license in order to research, develop or commercialize our product candidates, and we do not know if such patents and patent applications would be available to license on commercially reasonable terms, or at all. Any claims of patent infringement asserted by third parties would be time-consuming and may:

•

result in costly litigation;

•

divert the time and attention of our technical personnel and management;

•

prevent us from commercializing a product until the asserted patent expires or is held finally invalid or not infringed in a court of law;

•

require us to cease or modify our use of the technology and/or develop non-infringing technology; or

•

require us to enter into royalty or licensing agreements.

-28-

Although no third party has asserted a claim of infringement against us, others may hold proprietary rights that could prevent our product candidates from being marketed. We are aware of patents or patent applications owned by third parties that relate to some aspects of our programs that are still in development. In some cases, because we have not determined the final methods of manufacture, the method of administration or the therapeutic compositions for these programs, we cannot determine whether rights under such third-party positions will be needed. In addition, in some cases, we believe that the claims of these patents are invalid or not infringed or will expire before commercialization. However, if such patents are needed and found to be valid and infringed, we could be required to obtain licenses, which might not be available on commercially reasonable terms, or to cease or delay commercializing certain product candidates, or to change our programs to avoid infringement. Any patent-related legal action against us claiming damages and seeking to enjoin commercial activities relating to our product candidates or our processes could subject us to potential liability for damages and require us to obtain a license to continue to manufacture or market our product candidates. We cannot predict whether we would prevail in any such actions or that any license required under any of these patents would be made available on commercially acceptable terms, if at all. In addition, we cannot be sure that we could redesign any product candidates or processes to avoid infringement, if necessary. Accordingly, an adverse determination in a judicial or administrative proceeding, or the failure to obtain necessary licenses, could prevent us from developing and commercializing our product candidates, which could harm our business, financial condition, and operating results.

A number of companies, including several major pharmaceutical companies, have conducted research in the same therapeutic areas as our company, which resulted in the filing of many patent applications in the same areas as our research. If we were to challenge the validity of these or any U.S.-issued patent in court, we would need to overcome a statutory presumption of validity that attaches to every U.S.-issued patent. This means that, in order to prevail, we would have to present clear and convincing evidence as to the invalidity of the patent’s claims.

If we were to challenge the validity of these or any U.S. issued patent in an administrative trial before the Patent Trial and Appeal Board in the U.S. Patent and Trademark Office, we would have to prove that the claims are unpatentable by a preponderance of the evidence. There is no assurance that a jury and/or court would find in our favor on questions of infringement, validity, or enforceability.
