Notes to the Condensed Financial Statements (Unaudited)

Three and Six Month Periods Ended June 30, 2023 and 2022

1. Nature of Business, Basis of Presentation, and Liquidity

Nature of business:

Longeveron was formed as a Delaware limited liability company on October 9, 2014, and was authorized to transact business in Florida on December 15, 2014. On February 12, 2021, Longeveron, LLC converted its corporate form (the “Corporate Conversion”) from a Delaware limited liability company (Longeveron, LLC) to a Delaware corporation, Longeveron Inc. (the “Company,” “Longeveron” or “we,” “us,” or “our”). The Company is a clinical stage biotechnology company developing cellular therapies for specific aging-related and life-threatening conditions and operates out of its leased facilities in Miami, Florida.

The Company’s product candidates are currently in development. There can be no assurance that the Company’s research and development will be successfully completed, that adequate protection for the Company’s intellectual property will be obtained, that any products developed will obtain necessary government regulatory approval or that any approved products will be commercially viable. Even if the Company’s product development efforts are successful, it is uncertain when, if ever, the Company will generate significant revenue from product sales. The Company operates in an environment of rapid technological change and substantial competition from, among others, existing pharmaceutical and biotechnology companies. In addition, the Company is dependent upon the services of its employees, partners and consultants.

The accompanying interim condensed balance sheet as of June 30, 2023, and the condensed statements of operations, statement of comprehensive loss, stockholders’ equity, and cash flows for the three and six months ended June 30, 2023 and 2022, are unaudited. The unaudited condensed financial statements have been prepared according to the rules and regulations of the Securities and Exchange Commission (“SEC”) and, therefore, certain information and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) have been omitted. In the opinion of management, the accompanying unaudited condensed financial statements for the periods presented reflect all adjustments which are normal and recurring, and necessary to fairly state the financial position, results of operations, and cash flows of the Company. These unaudited condensed financial statements and notes should be read in conjunction with the audited financial statements and notes thereto in the Company’s 2022 Annual Report on Form 10-K filed with the SEC on March 14, 2023.

Liquidity:

Since inception, the Company has primarily been engaged in organizational activities, including raising capital, and research and development activities. The Company does not yet have a product that has been approved by the U.S. Food and Drug Administration (“FDA”), and has only generated revenues from grants, clinical trials and contract manufacturing. The Company has not yet achieved profitable operations or generated positive cash flows from operations. The Company intends to continue its efforts to raise additional equity financing, develop its intellectual property, and secure regulatory approvals to commercialize its products. There is no assurance that profitable operations, if achieved, could be sustained on a continuing basis. Further, the Company’s future operations are dependent on the success of the Company’s efforts to raise additional capital, its research and commercialization efforts, regulatory approval, and, ultimately, the market acceptance of the Company’s approved products, if any. These financial statements do not include adjustments that might result from the outcome of these uncertainties.

The Company has incurred recurring losses from operations since its inception, including a net loss of $10.3 million and $9.1 million for the six months ended June 30, 2023 and 2022, respectively. In addition, as of June 30, 2023, the Company had an accumulated deficit of $73.1 million. The Company expects to continue to generate operating losses for the foreseeable future.

As of June 30, 2023, the Company had cash, and cash equivalents of $2.7 million and marketable securities of $5.9 million. The Company has prepared a cash flow forecast which indicates that it does not have sufficient cash to meet its minimum expenditure commitments for one year from the date these condensed financial statements are available to be issued and therefore needs to raise additional funds to continue as a going concern. As a result, there is substantial doubt about the Company’s ability to continue as a going concern. To address the future funding requirements, management has undertaken the following initiatives:

●

On June 27,2023 the Company filed a registration statement with the SEC to conduct a tradeable subscription rights offering for up to $30.0 million of shares of Class A common stock to its stockholders and holders of warrants to purchase common stock as of a future record date to be determined. The Company expects to undertake and close the offering as outlined in the registration statement. On July 28, 2023 the Company filed a first amendment to the registration statement. The Company may seek additional capital in the private and/or public equity markets, to continue its operations, respond to competitive pressures, develop new products and services, and to support new strategic partnerships. The Company is evaluating additional equity/debt financing opportunities on an ongoing basis and may execute them when appropriate. However, there can be no assurances that the Company can consummate the rights offering or any transaction or consummate a transaction at favorable pricing or at all;

●

the Company will attempt to use equity instruments to provide a portion of the compensation due to vendors and collaboration partners;

●

the Company plans to pursue potential partnerships for pipeline programs, however, there can be no assurances that it can consummate such transactions;

●

the Company will continue to support its Bahamas Registry to generate revenue; and

●

since 2016 our clinical programs have received over $16.0 million in competitive extramural grant awards ($11.5 million which has been directly awarded to us and which are recognized as revenue when the performance obligations are met) from the National Institutes of Health (NIH), Alzheimer’s Association, and Maryland Stem Cell Research Fund (MSCRF), and the Company plans to submit additional contract and grant applications for further support of its programs with various funding agencies.

The Company’s condensed financial statements do not include any adjustments to the assets carrying amount, to the expenses presented and to the reclassification of the condensed balance sheets items that could be necessary should the Company be unable to continue its operations.

2. Summary of Significant Accounting Policies

Basis of presentation:

The financial statements of the Company were prepared in accordance with accounting principles generally accepted in the U.S. (“U.S. GAAP”).

Certain reclassifications have been made to prior year financial statements to conform to classifications used in the current year. These reclassifications had no impact on net loss, stockholders’ equity or cash flows as previously reported.

Use of estimates:

The presentation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Accounting Standard Updates

A variety of proposed or otherwise potential accounting standards are currently under consideration by standard-setting organizations and certain regulatory agencies. Because of the tentative and preliminary nature of such proposed standards, management has not yet determined the effect, if any, that the implementation of such proposed standards would have on the Company’s condensed financial statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments. The standard requires that credit losses be reported using an expected losses model rather than the incurred losses model that is currently used, and establishes additional disclosures related to credit risks. For available-for-sale debt securities with unrealized losses, these standards now require allowances to be recorded instead of reducing the amortized cost of the investment. These standards limit the amount of credit losses to be recognized for available-for-sale debt securities to the amount by which carrying value exceeds fair value and requires the reversal of previously recognized credit losses if fair value increases. The adoption of the standard as of January 1, 2023 did not have a material impact on the Company’s condensed financial statements; however, the Company did record net unrealized gains and losses in the condensed statement of comprehensive loss for the three and six month periods ended June 30, 2023.

Cash and cash equivalents:

The Company considers cash to consist of cash on hand and temporary investments having an original maturity of 90 days or less that are readily convertible into cash.

Marketable securities:

Marketable securities at June 30, 2023 and December 31, 2022 consisted of marketable fixed income securities, primarily corporate bonds, as well as U.S. Government and agency obligations which are categorized as trading securities and are thus marked to market and stated at fair value in accordance with ASC 820 Fair Value Measurement. These investments are considered Level 1 and Level 2 investments within the ASC 820 fair value hierarchy. The fair value of Level 1 investments, including cash equivalents, money funds and U.S. government securities, are substantially based on quoted market prices. The fair value of corporate bonds is determined using standard market valuation methodologies, including discounted cash flows, matrix pricing and/or other similar techniques. The inputs to these valuation techniques include but are not limited to market interest rates, credit rating of the issuer or counterparty, industry sector of the issuer, coupon rate, call provisions, maturity, estimated duration and assumptions regarding liquidity and estimated future cash flows. In addition to bond characteristics, the valuation methodologies incorporate market data, such as actual trades completed, bids and actual dealer quotes, where such information is available. Accordingly, the estimated fair values are based on available market information and judgments about financial instruments categorized within Level 1 and Level 2 of the fair value hierarchy. Interest and dividends are recorded when earned. Realized gains and losses on investments are determined by specific identification and are recognized as incurred in the statement of operations. Changes in net unrealized gains and losses are reported in other comprehensive loss and represent the change in the fair value of investment holdings during the reporting period. Changes in net unrealized gains and losses were less than $0.1 million for the three and six months ended June 30, 2023 and 2022.

Accounts and grants receivable:

Accounts and grants receivable include amounts due from customers, granting institutions and others. The amounts as of June 30, 2023 and December 31, 2022 are certain to be collected, and no amount has been recognized for doubtful accounts. In addition, for the Clinical trial revenue, most participants pay in advance of treatment. Advanced grant funds and prepayments for the Clinical trial revenue are recorded to deferred revenue.

Accounts and grants receivable by source, as of (in thousands):

	June 30, 2023		December 31, 2022
National Institutes of Health – Grant	$	96	$	218
Total	$	96	$	218

Deferred offering costs:

The Company recorded certain legal, professional and other third-party fees that were directly associated with in-process equity financings as deferred offering costs until the applicable equity financing was consummated. After consummation of an equity financing, these costs are recorded in stockholders’ equity as a reduction of proceeds generated as a result of the offering.

Property and equipment:

Property and equipment, including improvements that extend useful lives of related assets, are recorded at cost, while maintenance and repairs are charged to operations as incurred. Depreciation is calculated using the straight-line method based on the estimated useful lives of the assets. Leasehold improvements are amortized over the shorter of the estimated useful life of the asset or the original term of the lease. Depreciation expense is recorded in the research and development line of the condensed statements of operations as the assets are primarily related to the Company’s clinical programs.

Intangible assets:

Intangible assets include payments on license agreements with the Company’s co-founder and chief scientific officer (“CSO”) and the University of Miami (“UM”) (see Note 9) and legal costs incurred related to patents and trademarks. License agreements have been recorded at the value of cash consideration, common stock and membership units transferred to the respective parties when acquired.

Payments for license agreements are amortized using the straight-line method over the estimated term of the agreements, which range from 5-20 years. Patents are amortized over their estimated useful life, once issued. The Company considers trademarks to have an indefinite useful life and evaluates them for impairment on an annual basis. Amortization expense is recorded in the research and development line of the condensed statements of operations as the assets are primarily related to the Company’s clinical programs.

Impairment of Long-Lived Assets:

The Company evaluates long-lived assets for impairment, including property and equipment and intangible assets, when events or changes in circumstances indicate that the carrying value of such assets may not be recoverable. Upon the occurrence of a triggering event, the asset is reviewed to assess whether the estimated undiscounted cash flows expected from the use of the asset plus the residual value from the ultimate disposal exceeds the carrying value of the asset. If the carrying value exceeds the estimated recoverable amounts, the asset is written down to the estimated fair value. Any resulting impairment loss is reflected on the condensed statements of operations. Upon evaluation, management determined that there was no impairment of long-lived assets during the three and six months ended June 30, 2023 and 2022.

Deferred revenue:

The unearned portion of advanced grant funds and prepayments for clinical trial revenue, which will be recognized as revenue when the Company meets the respective performance obligations, has been presented as deferred revenue in the accompanying condensed balance sheets. For the six months ended June 30, 2023 and 2022, the Company recognized less than $0.1 million and $0.1 million, respectively of funds that were previously classified as deferred revenue ($0 and $0.1 million, respectively for the three months ended June 30, 2023 and 2022).

Revenue recognition:

The Company recognizes revenue when performance obligations related to respective revenue streams are met. For grant revenue, the Company considers the performance obligation met when the grant related expenses are incurred or supplies and materials are received. The Company is paid in tranches pursuant to terms of the related grant agreements, and then applies payments based on regular expense reimbursement submissions to grantors. There are no remaining performance obligations or variable consideration once grant expense reporting to the grantor is complete. For clinical trial revenue, the Company considers the performance obligation met when the participant has received the treatment. The Company usually receives prepayment for these services or receives payment at the time the treatment is provided, and there are no remaining performance obligations or variable consideration once the participant receives the treatment. For contract manufacturing revenue, the Company considers the performance obligation met when the contractual obligation and/or statement of work has been satisfied. Payment terms may vary depending on specific contract terms. There are no significant judgments affecting the determination of the amount and timing of revenue recognition.

Maryland Stem Cell Research Fund (MSCRF) - Maryland Technology Development Corporation (TEDCO)

The Company records cost of revenues based on expenses directly related to revenue. For Grants, the Company records allocated expenses for Research and development costs to a grant as a cost of revenues. For the Clinical trial revenue, directly related expenses for that program are expensed as incurred. These expenses are similar to those described under “Research and development expense” below.

Research and development expense:

Research and development costs are charged to expense when incurred in accordance with ASC 730 Research and Development. ASC 730 addresses the proper accounting and reporting for research and development costs. It identifies: 1) those activities that should be identified as research and development; 2) the elements of costs that should be identified with research and development activities, and the accounting for these costs; and 3) the financial statement disclosures related to them. Research and development costs include costs such as clinical trial expenses, contracted research and license agreement fees with no alternative future use, supplies and materials, salaries, share-based compensation, employee benefits, property and equipment depreciation and allocation of various corporate costs. The Company accrues for costs incurred by external service providers, including contract research organizations and clinical investigators, based on its estimates of service performed and costs incurred. These estimates include the level of services performed by the third parties, patient enrollment in clinical trials, administrative costs incurred by the third parties, and other indicators of the services completed. Based on the timing of amounts invoiced by service providers, the Company may also record payments made to those providers as prepaid expenses that will be recognized as expense in future periods as the related services are rendered.

Concentrations of credit risk:

Financial instruments which potentially subject the Company to credit risk consist principally of cash and cash equivalents, short-term investments and accounts and grants receivable. Cash and cash equivalents are held in U.S. financial institutions. At times, the Company may maintain balances in excess of the federally insured amounts.

Income taxes:

Prior to its Corporate Conversion, the Company was treated as a partnership for U.S. federal and state income tax purposes. Consequently, the Company passed its earnings and losses through to its members based on the terms of the Company’s Operating Agreement. Accordingly, no provision for income taxes is recorded in the financial statements for periods prior to the conversion.

Following the Corporate Conversion, the Company’s tax provision consists of taxes currently payable or receivable, plus any change during the period in deferred tax assets and liabilities. The Company uses the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. In addition, a valuation allowance is established to reduce any deferred tax asset for which it is determined that it is more likely than not that some portion of the deferred tax asset will not be realized. The Company’s tax provision was $0 for the three and six months ended June 30, 2023 and 2022 due to net operating losses. The Company has not recorded any tax benefit for the net operating losses incurred due to the uncertainty of realizing a benefit in the future.

The Company recognizes the tax benefits from uncertain tax positions that the Company has taken or expects to take on a tax return. In the unlikely event an uncertain tax position exists in which the Company could incur income taxes, the Company would evaluate whether there is a probability that the uncertain tax position taken would be sustained upon examination by a taxing authority. Reserves for uncertain tax positions would then be recorded if the Company determined it is probable that either a position would not be sustained upon examination or a payment would have to be made to a taxing authority and the amount was reasonably estimable. As of June 30, 2023 and December 31, 2022, the Company does not believe it has any uncertain tax positions that would result in the Company having a liability to a taxing authority. It is the Company’s policy to expense any interest and penalties associated with its tax obligations when they are probable and estimable.

Equity-based compensation:

The Company accounts for equity-based compensation expense by the measurement and recognition of compensation expense for stock-based awards based on estimated fair values on the date of grant. The fair value of the stock options is estimated at the date of the grant using the Black-Scholes option-pricing model.

The Black-Scholes option-pricing model requires the input of highly subjective assumptions, the most significant of which are the expected share price volatility, the expected life of the option award, the risk-free rate of return, and dividends during the expected term. Because the option-pricing model is sensitive to changes in the input assumptions, different determinations of the required inputs may result in different fair value estimates of the options.

Neither the Company’s stock options nor its restricted stock units (“RSUs”) trade on an active market. Volatility is a measure of the amount by which a financial variable, such as a stock price, has fluctuated (historical volatility) or is expected to fluctuate (expected volatility) during a period. Given the Company’s limited historical data, the Company utilizes the average historical volatility of similar publicly traded companies that are in the same industry. The risk-free interest rate is the average U.S. treasury rate (having a term that most closely approximates the expected life of the option) for the period in which the option was granted. The expected life is the period of time that the options granted are expected to remain outstanding. Options granted have a maximum term of ten years. The Company has insufficient historical data to utilize in determining its expected life assumptions and, therefore, uses the simplified method for determining expected life.

In part for his agreement to a general release the Company agreed to pay Dr. Min: $112,000 as severance compensation and allowed for the immediate acceleration and vesting of 40,000 RSUs that were previously granted.

RSUs are taxable upon vesting based on the market value on the date of vesting. The Company is required to make mandatory tax withholding for the payment and satisfaction of income tax, social security tax, payroll tax, or payment on account of other tax related to withholding obligations that arise by reason of vesting of an RSU. The taxable income is calculated by multiplying the number of vested RSUs for each individual by the closing share price as of the vesting date ($2.61 on April 3, 2023) and a tax liability is calculated based on each individual’s tax bracket.

On April 3, 2023, a total of 10,648 RSUs granted in connection with the Company’s IPO vested, of which 9,570 were held by Company employees.

Stock Options

Stock options may be granted under the 2021 Incentive Plan. The exercise price of options is set to equal the fair market value of the Company’s Class A Common Stock as of the grant date. Options historically granted have generally become exercisable over four years and expire ten years from the date of grant. The 2021 Incentive Plan provides for equity grants to be granted up to 5% of the outstanding common stock shares.

The fair value of the options issued is estimated using the Black-Scholes option-pricing model and using the following assumptions: a dividend yield of 0%; an expected life of 10 years; volatility of 95%; and risk-free interest rate based on the grant date ranging from of 1.23% to 4.01%. Each option grant made during 2023 and 2022 will be expensed ratably over the option vesting periods, which approximates the service period.

As of June 30, 2023 and December 31, 2022, the Company has recorded issued and outstanding options to purchase a total of 401,681, and 470,191 shares, respectively, of Class A Common Stock pursuant to the 2021 Incentive Plan, at a weighted average exercise price of $6.07, and $7.07 per share, respectively.

For the six months ended June 30, 2023:

	Number of Stock Options
Stock options vested (based on ratable vesting)		183,527
Stock options unvested		218,154
Total stock options outstanding at June 30, 2023		401,681

9. Commitments and Contingencies

Master Services Agreements:

As of June 30, 2023, the Company had three active master services agreements with third parties to conduct its clinical trials and manage clinical research programs and clinical development services on behalf of the Company. The Company expects these agreements or amended current agreements to have total expenditures of approximately $3.4 million over the next two years.

Consulting Services Agreements:

On November 20, 2014, the Company entered into a ten-year consulting services agreement with Dr. Joshua Hare, its CSO. Under the agreement, the Company has agreed to pay the CSO $265,000 annually. The compensation payments are for scientific knowledge, medical research, technical knowledge, skills, and abilities to be provided by the CSO to further develop the intellectual property rights assigned by the CSO to the Company. This agreement requires the CSO to also assign to the Company the exclusive right, title, and interest in any work product developed from his efforts during the term of this agreement. On November 16, 2022, the Company accounted for but had not issued 48,140 RSUs with an aggregate value of $0.2 million as payment for accrued expenses under the consulting agreement with the CSO. These shares were issued on May 24, 2023. As of June 30, 2023 and December 31, 2022, the Company had an accrued balance due to the CSO of less than $0.1 million.

Technology Services Agreement:

On March 27, 2015, the Company entered into a technology services agreement with Optimal Networks, Inc. (a related company owned by Dr. Joshua Hare’s brother-in-law) for use of information technology services. The Company agreed to issue the related party equity incentive units in the amount equal to 50% of the charges for invoiced services, with such equity to be issued annually on or about the anniversary date of the agreement. During 2017, the Company issued 1,901 Series C Units, and on November 22, 2019 and January 29, 2021, the Company issued 820 and 410 Series C Units, respectively, as payment for an aggregate of $0.2 million of accrued technology services.

Exclusive Licensing Agreements:

UM Agreement

On November 20, 2014, the Company entered into an Exclusive License Agreement with UM for the use of certain Aging-related Frailty MSC technology rights developed by our Chief Science Officer at UM. The UM License is a worldwide, exclusive license, with right to sublicense, with respect to any and all know-how specifically related to the development of the culture-expanded MSCs for Aging-related Frailty used at the IMSCs, all SOPs used to create the IMSCs, and all data supporting isolation, culture, expansion, processing, cryopreservation and management of the IMSCs. The Company is required to pay UM (i) a license issue fee of $5,000, (ii) a running royalty in an amount equal to three percent of annual net sales on products or services developed from the technology, payable on a country-by-country basis beginning on the date of first commercial sale through termination of the UM License Agreement, and which may be reduced to the extent we are required to pay royalties to a third party for the same product or process, (iii) escalating annual cash payments of up to $50,000, subject to offset. The agreement extends for up to 20 years from the last date a product or process is commercialized from the technology and was amended in 2017 to modify certain milestone completion dates as detailed below In 2021 the license fee was increased by an additional $100,000, to defray patent costs. In addition, the Company issued 110,387 unregistered shares of Class A Common Stock to UM.

The milestone payment amendments shifted the triggering payments to three payments of $500,000, to be paid within six months of: (a) the completion of the first Phase 3 clinical trial of the products (based upon the final data unblinding); (b) the receipt by the Company of approval for the first new drug application (“NDA”), biologics application (“BLA”), or other marketing or licensing application for the product; and (c) the first sale following product approval. “Approval” refers to Product approval, licensure, or other marketing authorization by the U.S. Food and Drug Administration, or any successor agency. The amendments also provided for the Company’s license of additional technology, to the extent not previously included in the UM License and granted the Company an exclusive option to obtain an exclusive license for (a) the HLHS investigational new drug application (“IND”) with ckit+ cells; and (b) UMP-438 titled “Method of Determining Responsiveness to Cell Therapy in Dilated Cardiomyopathy.”

The Company has the right to terminate the UM License upon 60 days’ prior written notice, and either party has the right to terminate upon a breach of the UM License. To date, the Company has made payments totaling $190,000 to UM, and as of June 30, 2023 and December 31, 2022, we had accrued $40,000 and $50,000 in milestone fees payable to UM, respectively and $70,000 for patent related reimbursements based on the estimated progress to date.

CD271

On December 22, 2016, the Company entered into an exclusive license agreement with an affiliated entity of Dr. Joshua Hare, JMH MD Holdings, LLC (“JMHMD”), for the use of CD271 cellular therapy technology. The Company recorded the value of the cash consideration and membership units issued to obtain this license agreement as an intangible asset. The Company is required to pay as royalty, 1% of the annual net sales of the licensed product(s) used, leased, or sold by or for licensee or its sub-licensees. If the Company sublicenses the technology, it is also required to pay an amount equal to 10% of the net sales of the sub-licensees. In addition, on December 23, 2016, as required by the license agreement, the Company paid an initial fee of $250,000 to JMHMD, and issued to it 10,000 Series C Units, valued at $250,000. The $0.5 million of value provided to JMHMD for the license agreement, along with professional fees of approximately $27,000, were recorded as an intangible asset that is amortized over the life of the license agreement which was defined as 20 years. Further, expenses related to the furtherance of the CD271 technology is being capitalized and amortized as incurred over 20 years. There were no license fees due during the six months ended June 30, 2023 or year ended December 31, 2022 pertaining to this agreement.

Other Royalty

Under the grant award agreement with the Alzheimer’s Association, the Company may be required to make revenue sharing or distribution of revenue payments for products or inventions generated or resulting from this clinical trial program. The potential payments, although not currently defined, could result in a maximum payment of five times (5x) the award amount.

Contingencies – Legal

On September 13, 2021, the Company and certain of its directors and officers were named as defendants in a securities lawsuit filed in the U.S. District Court for the Southern District of Florida and brought on behalf of a purported class. The suit alleges there were materially false and misleading statements made (or omissions of required information) in the Company’s initial public offering materials and in other disclosures during the period from our initial public offering on February 12, 2021, through August 12, 2021, in violation of the federal securities laws. The action sought damages on behalf of a proposed class of purchasers of the Company’s Common Stock during said period. On July 12, 2022, all parties preliminarily agreed to settle the action for approximately $1.4 million, which settlement was preliminarily approved by the Court on or about May 12, 2023, and which settlement amount was paid on May 24, 2023. Legal expenses incurred in ordinary business activities are reported within general and administrative expenses.

10. Employee Benefits Plan

The Company sponsors a defined contribution employee benefit plan (the “Plan”) under the provisions of Section 401(k) of the Internal Revenue Code. The Plan covers substantially all full-time employees of the Company who have completed one year of service. Contributions to the Plan by the Company are at the discretion of the Board of Directors.

The Company contributed approximately $0.1 million to the Plan during both of the six months ended June 30, 2023 and 2022, and less than $0.1 million for both of the three months ended June 30, 2023 and 2022.

11. Loss Per Share

Basic and diluted net loss per share have been computed using the weighted-average number of shares of common stock outstanding during the period. We have outstanding stock-based awards that are not used in the calculation of diluted net loss per share because to do so would be anti-dilutive.

The following instruments (in thousands) were excluded from the calculation of diluted net loss per share because their effects would be antidilutive:

Overview and Recent Developments

Overview

We are a clinical stage biotechnology company developing regenerative medicines to address unmet medical needs. The Company’s lead investigational product is Lomecel-B™, an allogeneic medicinal signaling cell (MSC) formulation sourced from bone marrow of young, healthy adult donors. Lomecel-B™ has multiple potential mechanisms of action that promote tissue repair and healing with broad potential applications across a spectrum of disease areas. The underlying mechanism(s) of action that lead to the tissue repair programs include the stimulation of new blood vessel formation, modulation of the immune system, reduction in tissue fibrosis, and the stimulation of endogenous cells to divide and increase the numbers of certain specialized cells in the body.

We are currently pursuing three pipeline indications: Hypoplastic Left Heart Syndrome (HLHS), Aging-related Frailty, and Alzheimer’s disease (AD). Our mission is to advance Lomecel-B™ and other cell-based candidates into pivotal Phase 3 trials, with the goal of achieving regulatory approvals, subsequent commercialization, and broad use by the healthcare community.

Our HLHS program is focused on the potential clinical benefits of Lomecel-B™ as an adjunct therapeutic to standard-of-care HLHS surgery. HLHS is a rare and devastating congenital heart defect in which the left ventricle is severely underdeveloped. As such, babies born with this condition die shortly after birth without undergoing a complex series of reconstructive heart surgeries. Despite the life-saving surgical interventions, clinical studies show that only 50 to 60 percent of affected individuals survive to adolescence. We have early clinical state evidence supporting pro-vascular, pro-regenerative, and anti-inflammatory properties of Lomecel-B™ to improve heart function in HLHS patients. We have completed a Phase 1 open-label study (ELPIS)¹ that supported the safety and tolerability of Lomecel-B™ for HLHS, when directly injected into the functional right ventricle during the second-stage standard-of-care surgery (adding minimal additional time to the surgical procedure). Preliminary data also suggested potential benefits on heart function. In addition, our early clinical stage data is favorable as compared to historical controls for survival and reduced need for heart transplants. Longeveron is currently conducting a controlled Phase 2a (ELPIS II)study which, if positive, could add to the clinical data suggesting the functional and clinical benefits of Lomecel-B™ in these patients.

Our other clinical programs focus on aging populations. Life-expectancy has substantially increased over the past century due to medical and public health advancements. However, this longevity increase has not been paralleled by healthspan – the period of time one can expect to live in relatively good health and independence. For many developed and developing countries, healthspan lags life-expectancy by over a decade. This has placed tremendous strain on healthcare systems in the management of aging-related ailments, and presents additional socioeconomic consequences due to patient decreased independence and quality-of-life. Since these strains continue to increase with demographic shifts towards an increasingly older population, improving healthspan has become a priority for health agencies, such as the National Institute on Aging (NIA) of the NIH, the Japanese Pharmaceuticals and Medical Devices Agency (PMDA), and the European Medicines Agency (EMA). As we age, we experience a decline in our own stem cells, a decrease in immune system function (known as “immunosenescence”), diminished blood vessel functioning, chronic inflammation (known as “inflammaging”), and other aging-related alterations that affect biological functioning. Our preliminary clinical data suggest that Lomecel-B™ can potentially address these problems through multiple mechanisms of action (MOAs) that simultaneously target key aging-related processes. Longeveron is currently engaged in clinical programs studying Lomecel-B™ for Alzheimer’s disease and Aging-related Frailty under INDs with the US FDA and under the PMDA in Japan, as well as using Lomecel-B™ in registry trials in The Bahamas.

Summary of Clinical Development Strategy

Our core mission is to become a world-leading regenerative medicine company through the development, approval, and commercialization of novel cell therapy products for unmet medical needs, with a focus on HLHS. Key elements of our current business strategy are as follows.

●

Execution of ELPIS II, a Phase 2 randomized controlled trial set forth in greater detail below, to measure the efficacy of Lomecel-B™ in HLHS. This trial is ongoing and is being conducted in collaboration with the National Heart, Lung, and Blood Institute (NHLBI) through grants from the NIH.

●

Continue developing our international programs. Japan is our first non-U.S. territory in which we are conducting a randomized, double-blinded, placebo-controlled clinical trial to evaluate Lomecel-B™ for Aging-related Frailty. With successful completion of this trial and demonstration of safety, we intend to seek marketing approval under the Act on the Safety of Regenerative Medicine (ASRM). We also intend to explore conditional or full approval in Japan of Lomecel-B™ under the Pharmaceuticals and Medical Devices (PMD) Act for the treatment of Aging-related Frailty in the future, which will be guided by results from this trial and potentially others in our Frailty program. We may also explore other indications in Japan, and potentially pursue Aging-related Frailty and other indications in additional international locations for further development and commercialization. We also continue to successfully enroll in our Frailty and Cognitive Impairment registry trials in The Bahamas, and are launching an Osteoarthritis registry trial.

●

Continue to pursue the therapeutic potential of Lomecel-B™ in Alzheimer’s disease (AD). We completed a Phase 1b study, which indicated the potential of Lomecel-B™ to preserve cognition in patients with mild AD through multiple potential mechanisms of action. Based on the outcomes of this trial, we are now conducting a Phase 2a randomized placebo-controlled trial (CLEAR MIND) to determine the safety and effects of up to four doses of Lomecel-B™ infused every 4 weeks in mild AD patients. This study entails a heavy focus on target engagement through multiple endpoints that include evaluation of fluid-based biomarkers, brain imaging, vascular function, and neurocognitive measures.

●

Expand our manufacturing capabilities to commercial-scale production. We operate a current good manufacturing practice (cGMP)-compliant manufacturing facility and produce our own product candidates for testing. We continue to improve and expand our capabilities with the goal of achieving cost-effective manufacturing that may potentially satisfy future commercial demand for potential Lomecel-B™ commercialization.

●

Collaborative arrangements and out-licensing opportunities. We will be opportunistic and consider entering into co-development, out-licensing, or other collaboration agreements for the purpose of eventually commercializing Lomecel-B™ and other products domestically and internationally if appropriate approvals are obtained.

●

Product candidate development pipeline through internal research and development, and in-licensing. Through our research and development program, and through strategic in-licensing agreements, or other business development arrangements, we intend to actively explore promising potential additions to our pipeline.

●

Continue to expand our intellectual property portfolio. Our intellectual property is vitally important to our business strategy, and we take significant steps to develop this property and protect its value. Results from our ongoing research and development efforts are intended to add to our existing intellectual property portfolio.

Clinical Development Pipeline in 2023

We are currently in clinical development of a single product, Lomecel-B™ for three potential indications (See Figure 1).

Figure 1: Lomecel-B™ clinical development pipeline

Hypoplastic Left Heart Syndrome (HLHS). The FDA granted Lomecel-B™ for the treatment of HLHS a Rare Pediatric Disease (RPD) Designation (on November 8, 2021), Orphan Drug Designation (ODD) (on December 2, 2021), and Fast Track Designation (on August 24, 2022). HLHS is a rare congenital heart condition that affects roughly 1,000 to 2,000 newborns annually in the US. HLHS babies are born with a severely underdeveloped left ventricle. To prevent certain death shortly after birth, these babies undergo a series of three heart surgeries that converts the normally 4-chamber heart into a 3-chamber one with a single ventricle (the right ventricle) supporting systemic circulation. Despite these life-saving surgeries, HLHS patients nevertheless still have high early mortality and morbidity rates due primarily to heart failure.

We are currently conducting an ongoing Phase 2 clinical trial (ELPIS II) under FDA IND 017677. ELPIS II is a multi-center, randomized, double-blind, controlled clinical trial designed to evaluate Lomecel-B™ as an adjunct therapy to the standard-of-care second-stage HLHS heart reconstructive surgery. The primary endpoint is to evaluate improvement in heart function after Lomecel-B™ treatment versus standard-of-care surgery alone (38 subjects total: 19 per arm). This trial is over 50% enrolled, and is funded in part by the NHLBI/NIH. While we cannot predict a specific time when the trial will be fully enrolled, the plan is to complete enrollment around mid-2024.

ELPIS II is a next-step trial to our completed 10-patient open-label Phase 1 trial (ELPIS) under the same IND. This Phase 1 trial was designed to evaluate the safety and tolerability of Lomecel-B™ as an adjunct to the second-stage HLHS surgery, and to obtain preliminary evidence of Lomecel-B™ effect to support a next-phase trial. The primary safety endpoint was met: no major adverse cardiac events (MACE) or treatment-related infections during the first month post-treatment, and no triggering of stopping rules. Furthermore, fluid-based and imaging biomarker data supported multiple potential relevant mechanisms-of-action of Lomecel-B™, and the potential to improve post-surgical heart function. In addition to the 12-month follow-up evaluation on ELPIS, we continue to follow these patients on an annual basis. All 10 patients remain alive without the need for a heart transplant for 3.5 to 5.0 years since treatment with Lomecel-B™ (updated as of May 9, 2023), and five have already successfully undergone the third-stage surgery. Based on historical data, over 15% of patients would be expected to have received a heart transplant or have died within 3-years after the second-stage surgery, rising to nearly 20% by 5 years.

We are prosecuting a number of patent applications relating to the administration of mesenchymal stem cells for treating juvenile HLHS in Taiwan and the Bahamas.

Aging-related Frailty. Aging-related Frailty is a life-threatening geriatric condition that disproportionately increases risks for poor clinical outcomes from disease and injury. While the definition of Aging-related Frailty lacks consensus and would be a new indication from a regulatory standpoint, and while Aging-related Frailty has no approved pharmaceutical or biologic treatments, there are a number of companies now working to develop potential therapeutics for this unmet medical need. We will work with regulatory agencies, such as the U.S. FDA and Japan’s PMDA, to advance Lomecel-B™ as potentially the first approved drug for Aging-related Frailty.

○

We have previously completed two U.S. clinical trials under FDA IND 016644. One is a multicenter, randomized, placebo-controlled Phase 2b trial which showed that a single infusion of Lomecel-B™ significantly improved 6-Minute Walk Test (6MWT) distance 9 months after infusion, and also showed a dose-dependent increase in 6MWT distance 6 months after infusion. The second is a multicenter, randomized, placebo-controlled Phase 1/2 trial (“HERA Trial”) that showed that Lomecel-B™ was generally safe and well tolerated in patient with Aging-related Frailty, and showed that hemagglutinin inhibition (HAI) assay results in the Lomecel-B™ and placebo groups to influenza were not statistically different, indicating Lomecel-B™ does not suppress the immune system.

Japan Clinical Trial: The Japanese PMDA has approved a Clinical Trial Notification (CTN), which is equivalent to a U.S. IND, allowing an Investigator-sponsored Phase 2 clinical study for Aging-related Frailty patients in Japan. This study is a 45-patient randomized placebo-controlled study with a primary objective of evaluating the safety of Lomecel-B™ in Japanese patients with Aging-related Frailty. Patient screening began in the 4^thquarter of 2022, and the first patient was randomized in the first quarter of 2023. The goal of this study is to enable ASRM approval when combined with previous clinical results in non-Japanese patients.

We are prosecuting a number of patent applications relating to the administration of mesenchymal stem cells for Aging-related Frailty in Taiwan, the Bahamas and United States.

Alzheimer’s disease. Alzheimer’s disease, a devastating neurologic disease leading to cognitive decline, has very limited therapeutic options. An estimated 6.7 million Americans age 65 and older have Alzheimer’s disease, and this number is projected to more than double by 2060. We have been testing Lomecel-B™ as a therapeutic with the possibility to slow the decline in cognitive function in patients with mild (i.e., early-stage) Alzheimer’s disease. Our completed and published Phase 1 clinical trial results suggest that Lomecel-B™ is safe in this population and does not cause Alzheimer Related Imaging Abnormality (ARIA), a serious complication of certain treatment strategies. Our early study also suggested the possibility of a therapeutic effect, and we are testing this possibility in a new Phase 2 clinical trial.

In the Phase 1 multicenter randomized placebo-controlled trial, patients received a single dose of Lomecel-B™ or placebo, and were evaluated for one year thereafter. The trial met its primary endpoint of safety (incidence of serious adverse events – SAEs – within one month of treatment), and supported the safety and tolerability of Lomecel-B™ through additional endpoint measures. Furthermore, through evaluation of blood-based and imaging biomarkers, neurocognitive assessments and quality-of-life measures, the trial provided insights into mechanisms of action of Lomecel-B™ for Alzheimer’s disease, as well as indications of potential to improve clinical outcomes².

The company is now conducting a next-step Phase 2a trial, CLEAR MIND, to evaluate multiple doses of Lomecel-B™ in patients with mild Alzheimer disease (ClinicalTrials.gov #NCT05233774). Each patient receives 4 treatments with Lomecel-B™, 4 treatments with placebo, or 1 treatment with Lomecel-B™ followed by 3 treatments with placebo, with each treatment delivered by intravenous (IV) infusion separated by 4 weeks. Patients are then followed for 9 months from the start of the first treatment. The primary objective is safety of multiple treatments with Lomecel-B™. This study also entails a rigorous evaluation of target engagement through endpoints that include evaluation of fluid-based biomarkers, brain imaging via magnetic resonance imaging (MRI), vascular function, and neurocognitive measures. Forty-nine (49) subjects have been enrolled and have received Lomacel-B™. The last patient visit is projected near the end of the third quarter of 2023, and topline CLEAR MIND results are expected around early October of 2023.

We are prosecuting a number of patent applications relating to the administration of allogenic mesenchymal stem cells for treating Alzheimer’s Disease in Hong Kong, South Africa, Singapore, Korea, New Zealand, Japan, Israel, Canada, Australia, the Bahamas, and the United States.


	○	The Bahamas Registry Trials: We sponsor and operate Registry Trials in Nassau and Lyford Cay in The Bahamas, where participants may receive Lomecel-B™ for Aging-related Frailty and other indications, at the participant’s own expense. Lomecel-B™ is designated as an investigational product in The Bahamas.

Impact of Macroeconomic Conditions

We have not to date been directly adversely impacted by the current banking sector volatility, and specifically the volatility being experienced within the regional banking sector volatility. However, we previously maintained deposits and marketable securities with a regional bank, and have made the determination, in light of such volatility and uncertainty, to transfer our deposits and marketable securities to a larger bank, so as to mitigate the likelihood of our experiencing a direct adverse impact from any ongoing or future volatility within the regional banking sector.

In addition, although we have experienced some supply constraints and marginal price increases, to date current macroeconomic conditions have not materially impacted our programs or our operations. We continue to monitor economic conditions in the U.S. and globally and expect to act proactively where possible to minimize the impact of continued inflation or supply constraints on materials and inventory needed for operations.

Components of Our Results of Operations

Revenue

We have generated revenue from three sources:

●

Grant awards. Extramural grant award funding, which is non-dilutive, has been a core strategy for supporting our ongoing clinical research. Since 2016 our clinical programs have received over $16.0 million in competitive extramural grant awards ($11.5 million which has been directly awarded to us and which are recognized as revenue when the performance obligations are met) from the NIH, Alzheimer’s Association, and Maryland Stem Cell Research Fund (MSCRF).

●

The Bahamas Registry Trial. Participants in The Bahamas Registry Trial pay us a fee to receive Lomecel-B™, imported into The Bahamas, and administered at one of two private medical clinics in Nassau. While Lomecel-B™ is considered an investigational product in The Bahamas, under the approval terms received from the National Stem Cell Ethics Committee, we are permitted to charge a fee for participation in the Registry Trial. The fee is recognized as revenue, and is used to pay for the costs associated with manufacturing and testing of Lomecel-B™, administration, shipping and importation fees, data collection and management, biological sample collection and sample processing for biomarkers and other data, and overall management of the Registry, including personnel costs. Lomecel-B™ is considered an investigational treatment in The Bahamas and is not licensed for commercial sale.

●

Contract development and manufacturing services. From time to time, we enter into fee-for-service agreements with third parties for our product development and manufacturing capabilities.

Cost of Revenues

We record cost of revenues based on expenses directly related to revenue. For grants we record allocated expenses for research and development costs to a grant as a cost of revenues. For the clinical trial revenue, directly related expenses for that program are allocated and accrued as incurred. These expenses are similar to those described under “Research and Development Expenses” below.

Selling and Marketing Expenses

Selling and marketing expenses consist primarily of royalty and license fees associated with our agreements with the University of Miami as well as attending and sponsoring industry, investment, organization and medical conferences and events.

Research and Development Expenses

Research and development costs are charged to expense when incurred in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 730 Research and Development. ASC 730 addresses the proper accounting and reporting for research and development costs. It identifies: first, those activities that should be identified as research and development; second, the elements of costs that should be identified with research and development activities, and the accounting for these costs; and third, the financial statement disclosures related to them. Research and development include costs such as clinical trial expenses, contracted research and license agreement fees with no alternative future use, supplies and materials, salaries, share-based compensation, employee benefits, property and equipment depreciation and allocation of various corporate costs. We accrue for costs incurred by external service providers, including contract research organizations (CROs) and clinical investigators, based on estimates of service performed and costs incurred. These estimates include the level of services performed by the third parties, subject enrollment in clinical trials, administrative costs incurred by the third parties, and other indicators of the services completed. Based on the timing of amounts invoiced by service providers, we may also record payments made to those providers as prepaid expenses that will be recognized as expense in future periods as the related services are rendered.

We currently do not carry any inventory for our product candidates, as we have yet to receive regulatory approval and launch a product for commercial distribution. Historically our operations have focused on conducting clinical trials, product research and development efforts, and improving and refining our manufacturing processes, and accordingly, manufactured clinical doses of product candidates were expensed as incurred, consistent with the accounting for all other research and development costs. Once we begin commercial distribution, all newly manufactured approved products will be allocated either for use in commercial distribution, which will be carried as inventory and not expensed, or for research and development efforts, which will continue to be expensed as incurred.

We expect that our research and development expenses will increase in the future as we increase our headcount to support increased research and development activities relating to our clinical programs, as well as incur additional expenses related to our clinical trials.

General and Administrative Expenses

General and administrative expenses consist primarily of salaries and other related costs, including stock-based compensation, for personnel in our executive, finance, business development and administrative functions. General and administrative expenses also include public company related expenses; legal fees relating to corporate matters; insurance costs; professional fees for accounting, auditing, tax and consulting services; travel expenses; and facility-related expenses, which include direct depreciation costs and allocated expenses for rent and maintenance of facilities and other operating costs.

We expect that our general and administrative expenses will increase in the future as we increase our headcount to support the administrative activities related to being a public company, including costs of accounting, audit, legal, regulatory and tax-related services associated with maintaining compliance with Nasdaq and SEC requirements, director and officer insurance costs, and investor and public relations costs.

Other Income and Expenses

Interest income consists of interest earned on cash equivalents and marketable securities. We expect our interest income to fluctuate due to changes in the current cash and marketable securities balances. Other income consists of funds earned that are not part of our normal operations. In past years they have been primarily a result of tax refunds received for social security taxes as part of a research and development tax credit program.

Income Taxes

As of February 12, 2021, we are treated as a C corporation for federal and state income tax purposes. Prior to February 12, 2021, we were treated as a partnership for federal and state income tax purposes, whereby we passed our earnings and losses through to our members based on the terms of our Operating Agreement. No provision for income taxes has been recorded for the years ended December 31, 2022 and 2021. We may incur income taxes in the future if we have earnings. At this time the Company has not evaluated the impact of any future profits.

Revenues, Cost of Revenues and Gross Profit: Revenues for each of the three months ended June 30, 2023 and 2022 were approximately $0.2 million and $0.5 million, respectively. Grant revenue for the three months ended June 30, 2023 and 2022 was $0 and $0.1 million, respectively. The decrease of $0.1 million, or 100%, was primarily due to a reduction in grant funds available due in part to the completion of the grant-funded clinical trials. Clinical trial revenue, which is derived from the Bahamas Registry Trial, for the three months ended June 30, 2023 and 2022 was $0.2 million and $0.3 million, respectively. Clinical trial revenue for the three months ended June 30, 2023 was approximately $0.1 million, or 36%, lower when compared to the same period in 2022 as a result of a decrease in participant demand.

Related cost of revenues was approximately $0.1 million and $0.3 million for the three months ended June 30, 2023 and 2022, respectively. The decrease of $0.2 million, or 59%, was primarily due to the decrease in the revenues earned from the Bahamas Registry Trial. This resulted in a gross profit of approximately $0.1 million and $0.2 million for the three months ended June 30, 2023 and 2022, respectively.

General and Administrative Expense: General and administrative expenses for the three months ended June 30, 2023 increased to approximately $3.4 million, compared to $2.4 million for the same period in 2022. The increase of approximately $1.0 million, or 39%, was primarily related to an increase of $0.7 million in compensation and benefit expenses during the current year period and expenses related to professional fees.

Research and Development Expenses: Research and development expenses for the three months ended June 30, 2023 increased to approximately $2.3 million, from approximately $1.7 million for the same period in 2022. The increase of $0.6 million, or 33%, was primarily due to an increase of $0.5 million in research and development expenses that were not reimbursable by grants. Research and development expenses consisted primarily of the following items (less those expenses allocated to the cost of revenues for the grants) (in thousands):

Revenues for the six months ended June 30, 2023 were approximately $0.3 million, or 41% lower when compared to the same period in 2022. Grant revenue for the six months ended June 30, 2023 and 2022 was less than $0.1 million and $0.2 million, respectively. Grant revenue for the six months ended June 30, 2023 was approximately $0.1 million, or 78% lower when compared to the same period in 2022, primarily due to a reduction in grant funds available due in part to the completion of the grant-funded clinical trials. Clinical trial revenue, which is derived from the Bahamas Registry Trial, for the six months ended June 30, 2023 and 2022 was $0.5 million and $0.6 million, respectively. Clinical trial revenue for the six months ended June 30, 2023 was approximately $0.1 million, or 30%, lower when compared to the same period in 2022. During the first half of 2023, clinical trial revenue decreased as a result of a decrease in participant demand.

Related cost of revenues was approximately $0.3 million and $0.4 million for the six months ended June 30, 2023 and 2022, respectively. Cost of revenues for the six months ended June 30, 2023 was $0.1 million, or 13%, less when compared to the same period in 2022, primarily due to the corresponding decrease in the revenues earned from the Bahamas Registry Trial. This resulted in a gross profit of approximately $0.2 million and $0.5 million for the six months ended June 30, 2023 and 2022, respectively.

General and Administrative Expense: General and administrative expenses for the six months ended June 30, 2023 increased to approximately $5.2 million, compared to $4.4 million for the same period in 2022. The increase of approximately $0.8 million, or 19%, was primarily related to an increase of $0.8 million in compensation and benefit expenses.

Research and Development Expenses: Research and development expenses for the six months ended June 30, 2023, increased to approximately $5.1 million, from approximately $3.1 million for the same period in 2022.

Cash Flows

The following table summarizes our sources and uses of cash for the period presented (in thousands):

	Six Months Ended June 30,
	2023			2022
Net cash used in operating activities	$	(10,449	)	$	(7,427	)
Net cash provided by investing activities		2,796			2,282
Net cash used in financing activities		(103	)		(289	)
Change in cash and cash equivalents	$	(7,756	)	$	(5,434	)

Operating Activities. We have incurred losses since inception. Net cash used in operating activities for the six months ended June 30, 2023 was $10.4 million, consisting primarily of our net loss of $10.3 million and payments for prepaid and other assets of $1.1 million and the non-operating lawsuit of $1.4 million. This was partially offset by non-cash expenses of $1.1 million in equity-based compensation expenses, $0.5 million in depreciation and amortization, and an increase in accrued expenses of $0.7 million. Net cash used in operating activities for the six months ended June 30, 2022 was $7.4 million, consisting primarily of our net loss of $9.1 million and payments for prepaid expenses and other assets of $0.8 million and accrued expenses of $0.5 million. This was partially offset by non-cash expenses of $3.3 million, primarily due to $1.4 million in non-operating lawsuit expenses, equity-based compensation expenses of $1.2 million, and depreciation and amortization of $0.4 million.

Investing Activities. Net cash provided by investing activities for the six months ended June 30, 2023 was $2.8 million consisting primarily of proceeds from the sale of marketable securities. Net cash provided by investing activities for the six months ended June 30, 2022 was $2.3 million, consisting primarily of proceeds from the sale of marketable securities.

Financing Activities. Net cash used in financing activities for the six months ended June 30, 2023 was $0.1 million for the payment of taxes upon vesting of RSUs. Net cash provided by financing activities for the six months ended June 30, 2022 was $0.3 million for the payment of taxes upon vesting of RSUs.

LIQUIDITY AND CAPITAL RESOURCES

Since our inception, we have incurred significant operating losses. We expect to incur significant expenses and operating losses as we advance the preclinical and clinical development of our programs. We expect that our sales, research and development and general and administrative costs will increase in connection with conducting additional preclinical studies and clinical trials for our current and future programs and product candidates, contracting with CROs to support preclinical studies and clinical trials, expanding our intellectual property portfolio, and providing general and administrative support for our operations. As a result, we will need additional capital to fund our operations, which we may obtain from additional equity or debt financings, collaborations, licensing arrangements, or other sources.

To date, we have financed our operations primarily through our IPO, private placement equity financings, grant awards, and fees generated from the Bahamas Registry Trial and contract manufacturing services. Since we were formed, we have raised approximately $77.2 million in gross proceeds from the issuance of equity. As of June 30, 2023, the Company had cash, and cash equivalents of $2.7 million, marketable securities of $5.9 million and working capital of approximately $6.2 million.

Capital Raising Efforts

In our IPO, we sold 2,910,000 shares of Class A Common Stock at a public offering price of $10.00 per share for aggregate gross proceeds of $29.1 million, inclusive of the underwriter’s partial exercise of its over-allotment option, prior to deducting underwriting discounts, commissions, and other offering expenses.

The underwriter received warrants to purchase 106,400 Class A Common Stock shares. The warrants are exercisable at any time and from time to time, in whole or in part, during the four and a half-year period commencing August 12, 2021, at a price of $12.00 per Class A Common Stock share. During 2021, the underwriters assigned 95,760 of the warrants to its employees. As of December 31, 2022, 51,061 warrants have been exercised, which provided net proceeds to the Company of $0.6 million.

On December 3, 2021, we closed a private purchase and sale to certain accredited investors of an aggregate of 1,169,288 shares of our Class A Common Stock and warrants to purchase 1,169,288 shares of Class A Common Stock at an initial exercise price of $17.50 per share, which are subject to pricing reset under certain conditions, resulting in aggregate gross proceeds of $20.5 million prior to deducting fees and offering expenses (the 2021 PIPE Offering”). We also issued warrants exercisable for 46,772 shares of Class A Common Stock to affiliates of the Placement Agent, with an initial exercise price of $17.50 per share, and are subject to the same pricing reset under certain conditions.

On June 27, 2023 we announced that we have filed a registration statement with the SEC to conduct a tradeable subscription rights offering for up to $30.0 million of shares of Class A common stock to our stockholders and holders of warrants to purchase common stock as of a future record date to be determined. We filed an amendment to the registration statement with the SEC on July 28, 2023 with additional details regarding the proposed offering We anticipate closing this transaction as outlined in the registration statement, as amended; however there can be no assurances that we can consummate this transaction or any subsequent transaction at favorable pricing or at all.

Grant Awards

Through June 30, 2023, we have been awarded approximately $11.9 million in governmental and non-profit association grants, which have been used to fund our clinical trials, research and development, production and overhead. Grant awards are recognized as revenue, and depending on the funding mechanism, are deposited directly in our accounts as lump sums, which are staggered over a predetermined period, or drawn down from a federal payment management system account for reimbursement of expenses incurred. Revenue recognition occurs when the grant related expenses are incurred, or supplies and materials are received. As of June 30, 2023, and December 31, 2022, the amount of unused grant funds that were available for us to draw was approximately $0.1 million and $0.8 million, respectively.

Terms and Conditions of Grant Awards

Grant projects are typically divided into periods (e.g., a three-year grant may have three one-year periods), and the total amount awarded is divided according to the number of periods. At pre-specified time points, which are detailed in the grant award notifications, we are required to submit interim financial and scientific reports to the granting agency totaling funds spent, and in some cases, detailing use of proceeds and progress made during the reporting period. After funding the initial period, receipt of additional grant funds is contingent upon satisfactory submission of our interim reports to the granting agency.

Grant awards arise from submitting detailed research proposals to granting agencies, and winning a highly competitive and rigorous application review and process that is judged on the merits of the proposal. There are typically multiple applicants applying and competing for a finite amount of funds. As such we cannot be sure that we will be awarded grant funds in the future despite our past success in receiving such awards.

Funding Requirements

Our operating costs will continue to increase substantially for the foreseeable future in connection with our ongoing activities. In past years we have been able to fund a large portion of our clinical programs and our administrative overhead with the use of grant funding.

Specifically, our expenses will increase as we:

●

advance the clinical development of Lomecel-B™ for the treatment of several disease states and indications;

●

pursue the preclinical and clinical development of other current and future research programs and product candidates;

●

in-license or acquire the rights to other products, product candidates or technologies;

●

maintain, expand and protect our intellectual property portfolio;

●

hire additional personnel in research, manufacturing and regulatory and clinical development as well as management personnel;

●

seek regulatory approval for any product candidates that successfully complete clinical development; and

●

expand our operational, financial and management systems and increase personnel, including personnel to support our operations as a public company.

We believe that our existing cash and cash equivalents will enable us to fund our operating expenses and capital expenditure requirements into the first quarter of 2024.We have based these estimates on assumptions that may prove to be imprecise, and we could utilize our available capital resources sooner than we expect.

Because of the numerous risks and uncertainties associated with research, development and commercialization of our product candidates, it is difficult to estimate with certainty the amount of our working capital requirements. Our future funding requirements will depend on many factors, including:

	●	the progress, costs and results of our clinical trials for our programs for our cell-based therapies, and additional research and preclinical studies in other research programs we initiate in the future;

	●	the costs and timing of process development and manufacturing scale-up activities associated with our product candidates and other programs we advance through preclinical and clinical development;

	●	our ability to establish and maintain strategic collaborations, licensing or other agreements and the financial terms of such agreements;

	●	the extent to which we in-license or acquire rights to other products, product candidates or technologies; and

	●	the costs and timing of preparing, filing and prosecuting patent applications, maintaining and protecting our intellectual property rights and defending against any intellectual property-related claims.

Further, our operating results may change in the future, and we may need additional funds to meet operational needs and capital requirements associated with such operating plans. Until such time, if ever, that we can generate product revenue sufficient to achieve profitability, we expect to finance our cash needs through a combination of equity offerings, debt financings, grant awards, collaboration agreements, other third-party funding, strategic alliances, licensing arrangements and marketing and distribution arrangements.

We currently have no credit facility or committed sources of capital. Debt financing and equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If we raise additional funds through other third-party funding, collaboration agreements, strategic alliances, licensing arrangements or marketing and distribution arrangements, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our biologic drug development or future commercialization efforts or grant rights to develop and market products or product candidates that we would otherwise prefer to develop and market ourselves.

In order to meet our operational goals, we will need to obtain additional capital, which we will likely obtain through a variety of means, including through public or private equity, debt financings or other sources, including up-front payments and milestone payments from strategic collaborations. To the extent that we raise additional capital through the sale of convertible debt or equity securities, current stockholder ownership interest will be diluted, and the terms may include liquidation or other preferences that adversely affect stockholder rights. Such financing will likely result in dilution to stockholders, and may result in imposition of debt covenants, increased fixed payment obligations or other restrictions that may affect our business. If we raise additional funds through up-front payments or milestone payments pursuant to strategic collaborations with third parties, we may have to relinquish valuable rights to our product candidates, or grant licenses on terms that are not favorable to us. In addition, we may seek additional capital due to favorable market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans.

Contractual Obligations and Commitments

As of June 30, 2023, we have $2.3 million in operating lease obligations and $1.2 million in CRO payment obligations. We enter into contracts in the normal course of business with third-party contract organizations for clinical trials, preclinical studies, manufacturing and other services and products for operating purposes. These contracts generally provide for termination following a certain period after notice and therefore we believe that our non-cancelable obligations under these agreements are not material.

We have not included milestone or royalty payments or other contractual payment obligations if the timing and amount of such obligations are unknown or uncertain.

Critical Accounting Policies and Use of Estimates

Our management’s discussion and analysis of financial condition, results of operations and liquidity are based on our condensed financial statements, which have been prepared in accordance with generally accepted accounting principles in the U.S. (“U.S. GAAP”). The preparation of our condensed financial statements and related disclosures requires us to make estimates, judgements and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the condensed financial statements and the reported amounts of revenues and expenses during the reporting period. We base our estimates on historical experience, known trends and events and various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may materially differ from these estimates under different assumptions or conditions. On an on-going basis, we review our estimates to ensure that they appropriately reflect changes in our business or new information as it becomes available.

While our significant accounting policies are described in more detail in the notes to our financial statements included in the 2022 10-K, we believe that the following accounting policies are those most critical due to the judgments and estimates used in the preparation of our condensed financial statements.

Impairment of Long-Lived Assets. We evaluate long-lived assets for impairment, including property and equipment and intangible assets, when events or changes in circumstances indicate that the carrying value of such assets may not be recoverable. Upon the occurrence of a triggering event, the asset is reviewed to assess whether the estimated undiscounted cash flows expected from the use of the asset plus the residual value from the ultimate disposal exceeds the carrying value of the asset. If the carrying value exceeds the estimated recoverable amounts, the asset is written down to the estimated fair value. Any resulting impairment loss is reflected on the condensed statements of operations. Management determined that there was no impairment of long-lived assets during the three months ended June 30, 2023 and 2022.

Revenue recognition. Effective January 1, 2018, we adopted ASC Topic 606, Revenue from Contracts with Customers, which establishes a single and comprehensive framework on how much revenue is to be recognized, and when. The core principle is that a vendor should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the vendor expects to be entitled in exchange for those goods or services. Revenue will be recognized by a vendor when control over the goods or services is transferred to the customer.

We recognize revenue when performance obligations related to respective revenue streams are met. For grant revenue, we consider the performance obligation met when the grant related expenses are incurred, or supplies and materials are received. For clinical trial revenue, we consider the performance obligation met when the participant has received the therapy. For contract manufacturing revenue, we consider the performance obligation met when the contractual obligation and/or statement of work has been satisfied.

Research and development expense. Research and development costs are charged to expense when incurred in accordance with FASB ASC 730, Research and Development. Research and development include costs such as clinical trial expenses, contracted research and license agreement fees with no alternative future use, supplies and materials, salaries, share-based compensation, employee benefits, property and equipment depreciation and allocation of various corporate costs. We accrue for costs incurred by external service providers, including contract research organizations and clinical investigators, based on estimates of service performed and costs incurred. These estimates include the level of services performed by the third parties, subject enrollment in clinical trials, administrative costs incurred by the third parties, and other indicators of the services completed. Based on the timing of amounts invoiced by service providers, we may also record payments made to those providers as prepaid expenses that will be recognized as expense in future periods as the related services are rendered.

Emerging Growth Company Status

We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act, or JOBS Act, which is a law intended to encourage funding of small businesses in the U.S. by easing many of the country’s securities regulations, and we may take advantage of reduced reporting requirements that are otherwise applicable to public companies. Section 107 of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies are required to comply with those standards. We have elected to take advantage of the extended transition period for complying with new or revised accounting standards, and as a result of this election, our financial statements may not be comparable to companies that comply with public company effective dates. The JOBS Act also exempts us from having to provide an auditor attestation of internal control over financial reporting under Sarbanes-Oxley Act Section 404(b).

We will remain an “emerging growth company” until the earliest of (1) the last day of the fiscal year in which we have total annual gross revenues of $1.07 billion or more, (2) the last day of the fiscal year following the fifth anniversary of the completion of our IPO, (3) the date on which we have issued more than $1.0 billion in nonconvertible debt during the previous three years or (4) the date on which we are deemed to be a large accelerated filer under the rules of the SEC, which generally is when a company has more than $700 million in market value of its reported class of stock held by non-affiliates and has been a public company for at least 12 months and has filed at least one Annual Report on Form 10-K.

Recent Accounting Pronouncements

A description of recent accounting pronouncements that may potentially impact our financial position, results of operations or cash flows is disclosed in Note 2 to our unaudited condensed financial statements included in Item 1 of this 10-Q.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

There were no material changes in our exposure to market risk since the disclosure included in Management’s Discussion and Analysis of Financial Condition and Results of Operations in our 2022 10-K.

Item 4. Controls and Procedures.

Disclosure controls and procedures

Our management, under the supervision of and with the participation of our Chief Executive Officer and our Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as of the end of the period covered by this Quarterly Report on Form 10-Q. Based upon this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of the period covered by this Quarterly Report on Form 10-Q, our disclosure controls and procedures were effective.

Changes in internal control over financial reporting

There were no changes in our internal control over financial reporting that occurred during the fiscal quarter ended June 30, 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

From time to time, the Company could become involved in disputes and various litigation matters that arise in the normal course of business. These may include disputes and lawsuits related to intellectual property, licensing, contract law and employee relations matters.

As previously disclosed in our 10-Q filed with the SEC on November 12, 2021, a securities class action lawsuit was filed on or about September 13, 2021 against the Company and certain of our directors and officers in the United States District Court for the Southern District of Florida. On or about April 26, 2022, plaintiff filed an amended complaint with related allegations. The complaint, as amended, alleged that there were materially false and misleading statements made (or omissions of material information) in the Company’s initial public offering documents and in other disclosures during the period from our initial public offering on February 12, 2021, through August 12, 2021, in violation of federal securities laws. The complaint sought unspecified damages on behalf of a purported class of purchasers of our common stock during said period. On July 12, 2022, all parties preliminarily agreed to settle the action for approximately $1.4 million, which amount was accrued as of June 30, 2022 and was paid during the quarter ended June 30, 2023.

Item 1A. Risk Factors.

Adverse developments affecting the financial services industry, such as actual events or concerns involving liquidity, defaults, or non-performance by financial institutions or transactional counterparties, could adversely affect the Company’s financial condition and results of operations.

Actual events involving limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions, transactional counterparties or other companies in the financial services industry or the financial services industry generally, or concerns or rumors about any events of these kinds or other similar risks, have in the past and may in the future lead to market-wide liquidity problems. For example, on March 10, 2023, Silicon Valley Bank (“SVB”) was closed by the California Department of Financial Protection and Innovation, which appointed the Federal Deposit Insurance Corporation (“FDIC”) as receiver. Further, on Monday, May 1, 2023, First Republic Bank (“FRB”) was closed by the California Department of Financial Protection and Innovation, the FDIC was appointed as receiver and JPMorgan Chase Bank, National Association (N.A.) acquired all of FRB’s deposit accounts and substantially all of its assets. Although we are not a borrower or party to any such instruments with SVB, FRB or any other financial institution currently in receivership, if any of our banking entities with which we do business were to be placed into receivership, we may be unable to access such funds. In addition, if any of our suppliers or other parties with whom we conduct business are unable to access funds pursuant to such instruments or lending arrangements with such a financial institution, such parties’ ability to satisfy their obligations to us or to enter into new commercial arrangements with us could be adversely affected. Uncertainty remains over liquidity concerns in the broader financial services industry, including financial institutions with which we do business, borrow money or have funds on deposit. The results of or concerns with events like this could include a variety of material and adverse impacts on the Company. In addition, investor concerns regarding the U.S. or international financial systems could result in less favorable commercial financing terms, including higher interest rates or costs and tighter financial and operating covenants, or systemic limitations on access to credit and liquidity sources, thereby making it more difficult for us to acquire financing on acceptable terms or at all. Any decline in available funding generally could, among other risks, adversely impact our ability to meet our operating demands or continue to develop our product candidates, or result in breaches of our financial and/or contractual obligations. Any of these impacts, or any other impacts resulting from the factors described above or other related or similar factors not described above, could have material adverse impacts on our liquidity and our current and/or projected business operations and financial condition and results of operations.
