Notes to Condensed Financial Statements (Unaudited)

Note 1. COMPANY AND NATURE OF BUSINESS

Vaccinex, Inc. (the “Company”) was incorporated in Delaware in April 2001 and is headquartered in Rochester, New York. The Company is a clinical-stage biotechnology company engaged in the discovery and development of targeted biotherapeutics to treat serious diseases and conditions with unmet medical needs, including cancer, neurodegenerative diseases, and autoimmune disorders. Since its inception, the Company has devoted substantially all of its efforts toward product research, manufacturing and clinical development, and raising capital.

The Company is subject to a number of risks and uncertainties common to other early-stage biotechnology companies including, but not limited to, dependency on the successful development and commercialization of its product candidates, rapid technological change and competition, dependence on key personnel and collaborative partners, uncertainty of protection of proprietary technology and patents, clinical trial uncertainty, fluctuation in operating results and financial performance, the need to obtain additional funding, compliance with governmental regulations, technological and medical risks, management of growth and effectiveness of marketing by the Company. If the Company does not successfully commercialize or partner any of its product candidates, it will be unable to generate product revenue or achieve profitability.

Going Concern

These condensed financial statements have been prepared in accordance with generally accepted accounting principles applicable to a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business.

The Company has incurred significant losses and negative cash flows from operations since inception and expects to incur additional losses until such a time it can generate significant revenue from the commercialization of its product candidates. The Company had negative cash flow from operations of $13.6 million for the nine months ended September 30, 2023, and an accumulated deficit of $336.6 million as of September 30, 2023. Given the Company’s projected operating requirements and its existing cash and cash equivalents, the Company is projecting insufficient liquidity to sustain its operations through one year following the date that the condensed financial statements are issued. These conditions and events raise substantial doubt about the Company’s ability to continue as a going concern.

In response to these conditions, management is currently evaluating different strategies to obtain the required funding of future operations. Financing strategies may include, but are not limited to, the public or private sale of equity, debt financing or funds from other capital sources, such as government funding, collaborations, strategic alliances, divestment of non-core assets, or licensing arrangements with third parties. There can be no assurances that the Company will be able to secure additional financing, or if available, that it will be sufficient to meet its needs or on favorable terms. Because management’s plans have not yet been finalized and are not within the Company’s control, the implementation of such plans cannot be considered probable. As a result, the Company has concluded that management’s plans do not alleviate substantial doubt about the Company’s ability to continue as a going concern.

The condensed financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of this uncertainty.

Note 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation and Consolidation

The accompanying unaudited condensed financial statements reflect the accounts and operations of the Company and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information (Accounting Standards Codification (“ASC”) 270, Interim Reporting) and with the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, these financial statements do not include all of the information necessary for a full presentation of financial position, results of operations, and cash flows in conformity with GAAP. In the opinion of management, the condensed financial statements reflect all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of the results of the Company for the periods presented.

These condensed financial statements should be read in conjunction with the Company’s audited financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, filed with the SEC on March 31, 2023.

Common Stock Reverse Split

On September 25, 2023, the Company effected a 1-for-15 reverse stock split of its issued shares of common stock (the "Reverse Stock Split"). All per share amounts, common shares outstanding and stock-based compensation amounts for all periods presented have been retroactively adjusted to reflect the Reverse Stock Split. The shares of common stock retain a par value of $0.0001 per share.

Use of Estimates

These condensed financial statements have been prepared in conformity with U.S. GAAP. The preparation 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 the disclosure of contingent assets and liabilities as of the date of the condensed financial statements and the reported amount of expenses during the reporting period. Such management estimates include those relating to assumptions used in the valuation of stock option awards, and valuation allowances against deferred income tax assets. Actual results could differ from those estimates.

Concentration of Credit Risk, Other Risks and Uncertainties

The Company is subject to a number of risks, including, but not limited to, the lack of available capital; the possible delisting of our common stock from Nasdaq, possible failure of preclinical testing or clinical trials; inability to obtain regulatory approval of product candidates; competitors developing new technological innovations; potential interruptions in the manufacturing and commercial supply operations; unsuccessful commercialization strategy and launch plans for its proprietary drug candidates; risks inherent in litigation, including purported class actions; market acceptance of the Company’s products; and protection of proprietary technology.

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents. Cash equivalents are deposited in interest-bearing money market accounts. Although the Company deposits its cash with multiple financial institutions, cash balances may occasionally be in excess of the amounts insured by the Federal Deposit Insurance Corporation. Management believes the financial risk associated with these balances is minimal and has not experienced any losses to date.

The Company has historically raised capital in transactions with investors that include members of its board of directors and entities controlled by certain board members. As such, the Company's directors, directly and indirectly, control a significant ownership percentage of the Company. The Company can provide no assurances that future financing will be available in sufficient amounts or on terms acceptable to it or that its directors or entities controlled by certain board members will be willing or able to participate in future capital raises by the Company.

The Company depends on third-party manufacturers for the manufacture of drug substances and drug product for clinical trials. The Company also relies on certain third parties for its supply chain. Disputes with these third- party manufacturers or shortages in goods or services from third-party suppliers could delay the manufacturing of the Company’s product candidates and adversely impact its results of operations.

Employee Retention Credit

The Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) provided refundable employee retention credits, which could be used to offset payroll tax liabilities. Under the provisions of the extension of the CARES Act, the Company qualified for the employee retention credit for the last three quarters of 2020, and first three quarters of 2021, and the Company applied for the credit in September 2023. As there is no authoritative guidance under U.S. GAAP for accounting for grants to for-profit business entities, the Company accounted for the grant by applying Accounting Standards Codification (“ASC”) 450, Contingencies. The Company recognized an employee retention credit receivable of $0.9 million as of September 30, 2023 in accounts receivable on the condensed balance sheet. The Company recognized the employee retention credit during the three and nine months ended September 30, 2023 as a component of other income (expense), net on the condensed statement of operations and comprehensive income (loss).

Recently Issued Accounting Pronouncements

In the normal course of business, the Company evaluates all new Accounting Standards Updates ("ASU") and other accounting pronouncements issued by the Financial Accounting Standards Board ("FASB"), Securities and Exchange Commission ("SEC"), or other authoritative accounting bodies to determine the potential impact they may have on its condensed financial statements. The Company does not expect any of the recently issued accounting pronouncements, which have not already been adopted, to have a material impact on its condensed financial statements.

Note 4. FAIR VALUE MEASUREMENTS OF FINANCIAL MEASUREMENTS

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

Assets and liabilities recorded at fair value on a nonrecurring basis in the condensed balance sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair values. Financial instruments consist of cash, accounts receivable, accounts payable, accrued liabilities, and long-term debt. Cash, accounts receivable, accounts payable, accrued liabilities, and debt, are stated at their carrying value, which approximates fair value due to the short time to the expected receipt or payment date of such amounts.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

Fair value measurement standards also apply to certain financial assets and liabilities that are measured at fair value on a recurring basis (each reporting period). For the Company, these financial assets and liabilities include its cash equivalents deposited in money market funds. The Company does not have any nonfinancial assets or liabilities that are measured at fair value on a recurring basis.

The assets’ or liabilities’ fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

The following table sets forth the fair value of the Company’s financial assets by level within the fair value hierarchy (in thousands):

As of September 30, 2023

The Company did not transfer any assets measured at fair value on a recurring basis to or from Level 1 and Level 2 during either of the nine months ended September 30, 2023 and 2022.

Note 5. COLLABORATION AGREEMENTS

Surface Oncology, Inc.

In November 2017, the Company entered into a research collaboration and license option agreement with Surface Oncology, Inc. (“Surface”) to identify and select antibodies against two target antigens, using the Company’s proprietary technology as described in the agreement. Under the agreement, Surface may purchase exclusive options, exercisable by providing a written notice to the Company, to obtain (i) an exclusive product license to make, use, sell and import products incorporating antibodies targeting the first antigen and (ii) an exclusive research tool license to use antibodies targeting the second antigen to perform research. Surface purchased the first option and exercised the second option and we entered into an exclusive research tool license agreement with Surface in the third quarter of 2019.

Under the research collaboration and license option agreement, Surface paid an upfront technology access fee of $250,000 and makes milestone payments upon completion of each of four designated milestones for the first target antigen specified in the agreement. For the second target antigen, Surface is obligated to make payments to the Company based on time incurred by the Company in the conduct of the work plan described in the agreement. Surface is required to reimburse the Company for expenses incurred (i) in the conduct of the work plan as detailed in the research funding budget and (ii) for patent filings and prosecution of the Company’s program intellectual property as described in the agreement. The exercise of each option would also entail a license fee and annual maintenance fees, and in the case of the product license, royalties and additional milestone payments. This agreement will expire upon the latest of the expiration of both research programs and all evaluation and testing periods. During the nine months ended September 30, 2023, the Company recorded $500,000 of revenue for achievement of a milestone event.

Note 6. COMMITMENTS AND CONTINGENCIES

Nasdaq Deficiency Notices

On October 10, 2022, the Company received a letter from the Listing Qualifications staff of The Nasdaq Stock Market ("Nasdaq") notifying the Company that it is no longer in compliance with the minimum bid price requirement for continued listing on the Nasdaq Capital Market. Nasdaq Listing Rule 5550(a)(2) requires listed companies to maintain a minimum bid price of $1.00 per share. In accordance with Nasdaq Listing Rule 5810(c)(3)(A), the Company received a second 180-day compliance period, or until October 9, 2023, to regain compliance with the minimum bid price requirement. The Company did not regain compliance by October 9, 2023 and received a notice from Nasdaq that its stock is subject to delisting. The Company appealed the delisting notice and has received an extension until March 4, 2024 to regain compliance with the minimum bid price requirement, subject to fulfilling its commitments to regain compliance by such date. There can be no assurance that the Company will be able to regain compliance with the Nasdaq minimum bid price requirements or that its common stock will continue to be listed on Nasdaq.

On May 25, 2023, the Company received a letter from the Listing Qualifications staff of Nasdaq notifying the Company that it no longer complies with the requirement under Nasdaq Listing Rule 5550(b)(1) to maintain a minimum of $2.5 million in stockholders’ equity for continued listing on the Nasdaq Capital Market (the “Equity Standard”) or the alternative requirements of having a market value of listed securities of $35.0 million or net income from continuing operations of $500,000 in the most recently completed fiscal year or two of the last three most recently completed fiscal years (the “Alternative Standards”). The notification letter noted that the Company’s Form 10-Q for the period ended March 31, 2023 disclosed stockholders’ equity of $2.4 million as of March 31, 2023 and that, as of May 24, 2023, the Company did not meet the Alternative Standards. The notification letter had no immediate effect on the Company’s listing on the Nasdaq Capital Market. Nasdaq provided the Company 45 calendar days from the date of the notification letter, or until July 9, 2023, to submit a plan to regain compliance with the Equity Standard (the “Compliance Plan”). A plan to regain compliance was submitted on July 7, 2023 and was accepted on July 18, 2023, and therefore the Company was granted an extension of up to 180 calendar days from the date of the notification letter, or until November 21, 2023, to regain compliance with the Equity Standard. As of September 30, 2023, we had a stockholder's deficit of $3.9 million and had not regained compliance with the Equity Standard.

On October 3, 2023 the Company’s raised aggregate gross proceeds of $9.6 million in a public offering of common stock and common stock equivalents, with accompanying warrants, discussed in Note 15 below. After conducting the public offering we received a letter from Nasdaq indicating we were in compliance with Nasdaq’s Equity Standard. We anticipate we will be in compliance with the Equity Standard for the period ended December 31, 2023. However, there can be no assurance that the Company will be able to regain or maintain compliance with the Equity Standard.

Other Contingencies

The Company is subject to claims and assessments from time to time in the ordinary course of business. The Company records a provision for a liability when it believes that it is both probable that a liability has been incurred and the amount can be reasonably estimated. Significant judgment is required to determine both probability and the estimated amount.

In the normal course of business, the Company may become involved in legal proceedings. The Company will accrue a liability for such matters when it is probable that a liability has been incurred and the amount can be reasonably estimated. When only a range of possible loss can be established, the most probable amount in the range is accrued. If no amount within this range is a better estimate than any other amount within the range, the minimum amount in the range is accrued. The accrual for a litigation loss contingency might include, for example, estimates of potential damages, outside legal fees and other directly related costs expected to be incurred. As of September 30, 2023 and December 31, 2022 the Company was not involved in any material legal proceedings.

Note 7. LEASES

The Company leases its facilities from 1895 Management, Ltd., a New York corporation controlled by an entity affiliated with a director of the Company, under non-cancellable operating leases. Following entry into a lease extension agreement in August 2022, the lease agreement requires monthly rental payments of $15,048 through October 31, 2024. The Company is responsible for all maintenance, utilities, insurance and taxes related to the facility. The Company has elected the practical expedient on not separating lease components from non-lease components.

The Company accounts for its leases under ASC 842, Leases. Leases with an initial term of 12 months or less are not recorded on the condensed balance sheet. The Company determines if an arrangement is a lease at inception. Right-of-use assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease right-of-use assets and lease liabilities are recognized based on the present value of lease payments over the lease term. The leases do not provide an implicit rate so in determining the present value of lease payments, the Company its incremental borrowing rate for the applicable lease, which was 7.0%. The Company recognizes lease expense on a straight-line basis over the remaining lease term.

As of September 30, 2023, the future minimum payments for the operating leases total $195,626, less imputed interest of $7,760, for an operating lease liability of $187,866 as of September 30, 2023. For the nine months ended September 30, 2023, cash paid for amounts included in the measurement of lease liabilities was $135,434.

Lease expense incurred under the operating lease for the three month periods ended September 30, 2023 and 2022 was $45,144 and $44,000 respectively, and $135,433 and $131,000 for the nine month periods ended September 30, 2023 and 2022, respectively. Lease expense is a component of general and administrative expense.

Note 8. LONG-TERM DEBT

On May 8, 2020, the Company received a loan under the Small Business Administration's Paycheck Protection Program (the "PPP Loan") in the amount of $1,133,600. The PPP Loan originally matured on May 8, 2022, with no principal payments required prior to the maturity date, and bearing interest at an annual rate of 1.0%, with interest payments commencing on November 8, 2020, less the amount of any potential forgiveness. On November 8, 2021, the Company was awarded loan forgiveness of $876,171 and the remaining balance of the loan was refinanced. The loan has a maturity date of May 8, 2025, bears interest of 1%, and is being repaid in monthly

payments of $6,334. The Company has recorded interest expense of $336 and $1,141 for the three and nine month periods ended September 30, 2023 and $523 and $1,764 for the three and nine month periods ended September 30, 2022, respectively on its condensed statements of operations and comprehensive loss.

Note 10. STOCK-BASED COMPENSATION

2011 Employee Equity Plan

In connection with the adoption of the Company’s 2018 Omnibus Incentive Plan (the “2018 Plan”) in August 2018, the Company ceased granting stock options under the Company’s 2011 Employee Equity Plan (the “2011 Plan”). However, the 2011 Plan will continue to govern the terms and conditions of the outstanding stock options previously granted thereunder. Any shares of stock related to awards outstanding under the 2011 Plan that terminate by expiration, forfeiture, cancellation, or otherwise without the issuance of such shares will become available for grant under the 2018 Plan. Stock options granted under the 2011 Plan expire in five or ten years from the date of grant.

2018 Omnibus Incentive Plan

In August 2018, the Company’s board of directors adopted, and its stockholders approved, the 2018 Plan, which allows for the granting of stock, stock options, and stock appreciation rights awards to employees, advisors and consultants. Stock options granted under the 2018 Plan may be either incentive stock options or non-statutory stock options. Incentive stock options may be granted to employees, advisors and consultants at exercise prices of no less than the fair value of the common stock on the grant date. If at the time of grant, the optionee owns stock representing more than 10% of the voting power of all classes of stock of the Company, the exercise price must be at least 110% of the fair value of the common stock on the grant date as determined by the board of directors. Non-statutory stock options may be granted to employees, advisors and consultants at exercise prices of less than the fair market value of a share of common stock on the date the non-statutory stock option is granted but shall under no circumstances be less than adequate consideration as determined by the board of directors for such a share. The vesting period of stock option grants is determined by the board of directors, ranging from zero to eight years. Stock options granted under the 2018 Plan expire in five or ten years from the date of grant.

The Company initially reserved 28,333 shares of common stock for issuance, subject to certain adjustments, pursuant to awards under the 2018 Plan. Any shares of common stock related to awards outstanding under the 2011 Plan as of the effective date of the 2018 Plan, which thereafter terminate by expiration, forfeiture, cancellation or otherwise without the issuance of such shares, will be added to, and included in, the number of shares of common stock available for grant under the 2018 Plan. In addition, effective January 1, 2020 and continuing until the expiration of the 2018 Plan, the number of shares of common stock available for issuance under the 2018 Plan will automatically increase annually by 2% of the total number of issued and outstanding shares of the Company’s common stock as of December 31 of the preceding year or such lesser number as the Company’s board of directors may decide, which may be zero. Accordingly, on January 1, 2023, 66,508 additional shares of common stock became available for issuance under the 2018 Plan.

A summary of the Company’s stock option activity and related information is as follows:


	Stock Options			Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Life (Years)		Aggregate Intrinsic Value (in thousands)
Balance as of January 1, 2023		118,795		$	59.68		7.1	$	4

Exercisable as of September 30, 2023		95,956		$	56.76		6.4	$	-

The weighted-average grant date fair value of stock options granted to employees and directors for the nine months ended September 30, 2023 and 2022 was $4.15 per share and $11.94 per share, respectively. The aggregate grant date fair value of stock options that vested during the nine months ended September 30, 2023 and 2022 was $513,718 and $604,626, respectively.

The intrinsic value of stock options vested and exercisable and expected to vest and become exercisable is calculated based on the difference between the exercise price and the fair value of the Company’s common stock as of September 30, 2023 and December 31, 2022. The intrinsic value of exercised stock options is the difference between the fair value of the underlying common stock and the exercise price as of the exercise date.

As of September 30, 2023 and December 31, 2022, total unrecognized compensation cost related to stock options granted to employees was $572,490 and $561,198, respectively, which is expected to be recognized over a weighted-average period of 2.2 and 2.1 years, respectively.

The grant date fair value of employee stock options was estimated using a Black-Scholes option-pricing model with the following weighted-average assumptions:


	Nine Months Ended September 30,
	2023			2022
Expected term (in years)		6.0			6.0
Expected volatility		75	%		75	%
Risk-free interest rate		3.7	%		2.3	%

Note 11. INCOME TAXES

No provision for income taxes was recorded in either of the three or nine month periods ended September 30, 2023 and 2022. The Company remains in a cumulative loss position with a full valuation allowance recorded against its net deferred income tax assets as of September 30, 2023.

The Company evaluates tax positions for recognition using a more-likely-than-not recognition threshold, and those tax positions eligible for recognition are measured as the largest amount of tax benefit that is greater than 50% likely of being realized upon the effective settlement with a taxing authority that has full knowledge of all relevant information. As of September 30, 2023 and December 31, 2022, the Company had no unrecognized income tax benefits that would affect the Company’s effective tax rate if recognized.

Note 12. NET LOSS PER SHARE ATTRIBUTABLE TO COMMON STOCKHOLDERS

The following weighted-average common stock equivalents were excluded from the calculation of diluted net loss per share for the periods presented as they had an anti-dilutive effect:

Company Overview

We are a clinical-stage biotechnology company engaged in the discovery and development of targeted biotherapeutics to treat serious diseases and conditions with unmet medical needs, including neurodegenerative diseases, cancer, and autoimmune disorders. We believe we are the leader in the field of semaphorin 4D, or SEMA4D, biology and that we are the only company targeting SEMA4D as a potential treatment for neurodegenerative diseases, cancer, and autoimmune disorders. SEMA4D is an extracellular signaling molecule that regulates the activity of immune and inflammatory cells at sites of injury, cancer, or infection. We are leveraging our SEMA4D antibody platform and our extensive knowledge of SEMA4D biology to develop our lead product candidate, pepinemab, an antibody that we believe utilizes novel mechanisms of action. We are focused on developing pepinemab for the treatment of Alzheimer’s disease, Huntington’s disease, head and neck cancer, and pancreatic cancer. Additionally, third party investigators are studying pepinemab in clinical trials in breast cancer, as well as in “window of opportunity” studies in other indications, including head and neck cancer, and melanoma. We have developed multiple proprietary platform technologies and are developing product candidates to address serious diseases or conditions that have a substantial impact on day-to-day functioning and for which treatment is not addressed adequately by available therapies. We employ our proprietary platform technologies, including through our work with our academic collaborators, to identify potential product candidates for sustained expansion of our internal product pipeline and to facilitate strategic development and commercial partnerships.

Our lead platform technologies include our SEMA4D antibody platform and our ActivMAb antibody discovery platform. Our lead product candidate, pepinemab, is currently in clinical development for the treatment of Alzheimer’s disease, head and neck, pancreatic and breast cancer, through our efforts or through investigator-sponsored trials. Our additional product candidate VX5 is in an earlier stage of development and was selected using our ActivMAb platform. We believe our multiple platform technologies position us well for continued pipeline expansion and partnership opportunities going forward.

We have generated a limited amount of service revenue from collaboration agreements but have not generated any revenue from product sales to date. We continue to incur significant development and other expenses related to our ongoing operations. As a result, we are not and have never been profitable and have incurred losses in each period since our inception, resulting in substantial doubt in our ability to continue as a going concern. We reported a net loss of $4.9 million and $4.8 million for the three months ended September 30, 2023 and 2022, respectively, and a net loss of $16.9 million and $14.7 million for the nine months ended September 30, 2023 and 2022, respectively. As of September 30, 2023, and December 31, 2022, we had cash and cash equivalents of $0.1 million and $6.4 million, respectively. We expect to continue to incur significant losses for the foreseeable future, and we expect these losses to increase as we continue our research and development of, and seek regulatory approvals for, our product candidates. We may also encounter unforeseen expenses, difficulties, complications, delays and other unknown factors which may adversely affect our business. The size of our future net losses will depend, in part, on the rate of future growth of our expenses and our ability to generate revenues, if any.

Our recurring net losses and negative cash flows from operations raised substantial doubt regarding our ability to continue as a going concern within one year after the issuance of our condensed financial statements for the three and nine months ended September 30, 2023. Until we can generate sufficient revenue from the commercialization of our product candidates, we expect to finance our operations through the public or private sale of equity, debt financing or other capital sources, such as government funding, collaborations, strategic alliances, divestment of non-core assets, or licensing arrangements with third parties. To date, the Company has relied on equity and debt financing to fund its operations, in addition to capital contributions from noncontrolling interests and a limited amount of service revenue from collaboration agreements. On March 30, 2023, the Company entered into a stock purchase agreement pursuant (the “Stock Purchase Agreement”) to which the Company issued and sold 331,708 shares of its common stock to affiliated investors, at a purchase price of $6.15 per share for aggregate gross proceeds of $2.04 million. On May 12, 2023, pursuant to the March 2023 Stock Purchase Agreement, the Company issued and sold to certain investors 527,234 shares of its common stock at a purchase price of $5.6142 per share for aggregate gross proceeds of $2.96 million (the "May 2023 Private Placement”). FCMI Parent Co. ("FCMI"), the Company's largest stockholder, purchased 447,437 shares of our common stock in the May 2023 Private Placement for a purchase price of $2.51 million. Albert D. Friedberg, the Company’s chairman and beneficial owner of a majority of the Company’s outstanding common stock, controls FCMI. In May 2023, the Company received $1.0 million through an award from the Alzheimer’s Drug Discovery Foundation in the form of an investment in our common stock. On August 18, 2023, we entered into a Stock Purchase Agreement, pursuant to which we issued and sold 209,340 shares of our common stock at a purchase price of $3.105 per share for aggregate gross proceeds of $0.65 million. On September 20, 2023, the Company entered into the Stock Purchase Agreement, pursuant to which the Company issued and sold 248,932 shares of its common stock at a purchase price of $2.34 per share for aggregate gross proceeds of $0.58 million (the "September 2023 Private Placement”). Vaccinex (Rochester) L.L.C. purchased 136,752 shares of the Company's common stock in the September 2023 Private Placement for a purchase price of $0.32 million.

Our cash and cash equivalents were $0.1 million and total current assets were $2.2 million at September 30, 2023, which will be insufficient to fund our planned operations through one year of the date that these condensed financial statements are available for issuance. See Note 1 of our unaudited condensed financial statements.

Nasdaq Deficiency Notices

On October 10, 2022, the Company received a letter from the Listing Qualifications staff of The Nasdaq Stock Market ("Nasdaq") notifying the Company that it is no longer in compliance with the minimum bid price requirement for continued listing on the Nasdaq Capital Market. Nasdaq Listing Rule 5550(a)(2) requires listed companies to maintain a minimum bid price of $1.00 per share. In accordance with Nasdaq Listing Rule 5810(c)(3)(A), the Company received a second 180-day compliance period, or until October 9, 2023, to regain compliance with the minimum bid price requirement. The Company did not regain compliance by October 9, 2023 and received a notice from Nasdaq that our stock is subject to delisting. The Company appealed the delisting notice and has received an extension until March 4, 2024 to regain compliance with the minimum bid price requirement, subject to fulfilling its commitments to regain compliance by such date. There can be no assurance that we will be able to regain compliance with the Nasdaq minimum bid price requirement or that our common stock will continue to be listed on Nasdaq.

minimum of $2.5 million in stockholders’ equity for continued listing on the Nasdaq Capital Market (the “Equity Standard”) or the alternative requirements of having a market value of listed securities of $35.0 million or net income from continuing operations of $500,000 in the most recently completed fiscal year or two of the last three most recently completed fiscal years (the “Alternative Standards”). The notification letter noted that the Company’s Form 10-Q for the period ended March 31, 2023 disclosed stockholders’ equity of $2.4 million as of March 31, 2023 and that, as of May 24, 2023, the Company did not meet the Alternative Standards. The notification letter had no immediate effect on the Company’s listing on the Nasdaq Capital Market. Nasdaq provided the Company 45 calendar days from the date of the notification letter, or until July 9, 2023, to submit a plan to regain compliance with the Equity Standard (the “Compliance Plan”). A plan to regain compliance was submitted on July 7, 2023 and was accepted on July 18, 2023, and therefore the Company was granted an extension of up to 180 calendar days from the date of the notification letter, or until November 21, 2023, to regain compliance with the Equity Standard. As of September 30, 2023, we had a stockholders' deficit of $3.9 million and had not regained compliance with the Equity Standard. On October 3, 2023 the Company raised aggregate gross proceeds of $9.6 million in a public offering of common stock and common stock equivalents, with accompanying warrants, discussed in Note 15 to the financial statements. After conducting the public offering received a letter from Nasdaq indicating we were in compliance with Nasdaq’s Equity Standard. We anticipate we will be in compliance with the Equity Standard for the period ended December 31, 2023. However, there can be no assurance that the Company will be able to retain or maintain compliance with the Equity Standard.

Corporate Update

On September 20, 2023, the Company entered into the Stock Purchase Agreement, pursuant to which the Company issued and sold 248,932 shares of its common stock at a purchase price of $2.34 per share for aggregate gross proceeds of $0.58 million (the "September 2023 Private Placement”). Vaccinex (Rochester) L.L.C., purchased 136,752 shares of the Company’s common stock in the September 2023 Private Placement for a purchase price of $0.32 million.

On September 22, 2023, the Company filed a Certificate of Amendment (the “Amendment”) to the Company’s Amended and Restated Certificate of Incorporation, with the Delaware Secretary of State to implement a reverse stock split of the Company’s issued shares of common stock at a ratio of 1-for-15, effective at 5:00 p.m. Eastern Time on September 25, 2023 (the “Reverse Stock Split”), previously approved by the Company’s Board of Directors and the Company’s stockholders. As a result of the Reverse Stock Split, every fifteen shares of the Company’s issued common stock were automatically combined into one share of common stock. The Reverse Stock Split affected all stockholders uniformly and did not alter any stockholders’ percentage interest in the Company’s common stock, except to the extent that the Reverse Stock Split resulted in any of our stockholders receiving whole shares in lieu of fractional shares, as any fractional shares resulting from the Reverse Stock Split were rounded up to the nearest whole share. Proportionate adjustments for the Reverse Stock Split were made to the exercise prices and number of shares issuable under the Company’s equity incentive plans, and the number of shares underlying outstanding equity awards, as applicable. The Reverse Stock Split did not change the par value of the common stock, modify any voting rights or other terms of the common stock, or change the number of authorized shares of the Company.

The Company’s common stock began trading on the Nasdaq Stock Market on a post-Reverse Stock Split basis under the Company’s existing trading symbol “VCNX” when the market opened on September 26, 2023. The new CUSIP number for the Company’s common stock post-Reverse Stock Split is 918640202.

On November 2, 2023, the Company entered into Securities Purchase Agreements with certain investors from the August and September 2023 private placements, pursuant to which the Company issued and sold 527,714 warrants to purchase up to 527,714 shares of its common stock at a purchase price of $0.125 per warrant for aggregate gross proceeds of $70,000. Vaccinex (Rochester) L.L.C. purchased 136,752 warrants in the November Warrant Offering for a purchase price of $17,000.

Clinical Update

As prespecified in the study protocol, the Company analyzed interim data from the first 36 patients in the open-label, single-arm, Phase 2 KEYNOTE B-84 study (NCT04815720) evaluating pepinemab and KEYTRUDA™ in immunotherapy naïve patients with recurrent or metastatic head and neck squamous cell carcinoma (HNSCC). The study was based on preclinical and clinical studies demonstrating that antibody blockade of semaphorin 4D (SEMA4D) in combination with immune checkpoint inhibitors (ICI) promotes infiltration of CD8+ cytotoxic T cells and inhibits the recruitment and function of myeloid derived suppressor cells (MDSC) in tumors, enabling enhanced ICI efficacy. The study results showed that pepinemab in combination with KEYTRUDA™ resulted in an approximately 2X increase in objective responses (ORR) and median progression free survival (PFS) in patients with hard-to-treat PD-L1-low tumors, those with combined positive score <20 (CPS<20), compared to historical response rates for ICI monotherapy in this population. ORR for the CPS<20 population was 21.1% with median PFS of 5.79 months, which is almost 2X that of historical response to checkpoint monotherapy in this population, ORR 11.9% and PFS 2.2 months. In contrast, patients in the CPS>20 subgroup (n=17) responded similarly to historical ICI monotherapy data. Biopsy data suggest that treatment-induced formation of highly organized lymphoid aggregates, tertiary lymphoid structures (TLS), correlate with disease control. TLS are characterized by a high density of B cells, antigen-presenting dendritic cells and activated T cells including stem-like TCF-1+, PD-1+, CD8+ T cells whose expansion and differentiation has previously been shown to be central for response to checkpoint inhibitors. The safety of pepinemab in combination with KEYTRUDA is regularly reviewed by an independent safety committee and has to date been found to be well tolerated.

In June 2023 the Company and its collaborators presented two posters in the “Trial in Progress” sessions at the American Society for Clinical Oncology (“ASCO23”):

•

Phase 1b/2 PDAC Study: The team from University of Rochester Cancer Center and Wilmot Cancer Institute presented the plan for the single-arm, open-label study to evaluate pepinemab in combination with BAVENCIO®(avelumab) as second line combination immunotherapy for patients with metastatic pancreatic ductal adenocarcinoma (PDAC, TPS4195, NCT05102721). The Company-sponsored study will employ a Bayesian Optimal Interval (BOIN) Design in the Phase 1b segment and a Simon two stage assessment in the Phase 2 segment and is expected to enroll 40 subjects. The trial rationale is supported by data from prior studies suggesting that pepinemab may reduce immune suppression in the TME, rendering “cold” tumors such as PDAC to become “hot” and enhancing efficacy of ICIs such as avelumab. The study is being conducted with grant support from the Gateway Discovery Award.

•

Phase 1 Metastatic Breast Cancer Study: The team from the Moffitt Cancer Center presented the plan for an open-label, Phase I study to evaluate up to 28 patients with HER2+ metastatic breast cancer (MBC, TPS1113, NCT05378464). Patients will receive a pulsed combination of dendritic cell vaccines (DC1) plus trastuzumab (an anti-HER-2 antibody) and pepinemab followed by treatment with HER2-specific T cells and lymphodepletion. The study rationale builds on results of the CLASSICAL Lung study of pepinemab and avelumab in lung cancer and the observation that pepinemab appears to modulate the TME by increasing effector cell infiltration and reducing immunosuppression.

Financial Overview

Revenue

To date, we have not generated any revenue from product sales. During the nine months ended September 30, 2023, we generated $500,000 from our collaboration agreement with Surface Oncology, and $70,000 of service revenue.

Our ability to generate revenue and become profitable depends on our ability to successfully obtain marketing approval of and commercialize our product candidates. We do not expect to generate product revenue in the foreseeable future as we continue our development of, and seek regulatory approvals for, our product candidates, and potentially commercialize approved products, if any.

Operating Expenses

Research and Development. Research and development expenses consist primarily of costs for our clinical trials and activities related to regulatory filings, employee compensation-related costs, supply expenses, equipment depreciation and amortization, consulting and other miscellaneous costs. The following table sets forth the components of our research and development expenses and the amount as a percentage of total research and development expenses for the periods indicated.


	Three Months Ended September 30,										Nine Months Ended September 30,
	2023					2022					2023					2022

Total research and development expenses	$	4,355				$	3,429				$	13,217				$	10,238

We expense research and development costs as incurred. We record costs for certain development activities, such as clinical trials, based on an evaluation of the progress to completion of specific tasks using data such as patient enrollment. We do not allocate employee-related costs, depreciation, rental and other indirect costs to specific research and development programs because these costs are deployed across multiple product programs under research and development.

Our current research and development activities primarily relate to clinical development in the following indications:

•

Alzheimer’s Disease. In April 2023, we reached our enrollment target of 49 participants for the Phase 1b/2 SIGNAL-AD study evaluating pepinemab as a potential treatment for people with mild dementia due to Alzheimer's disease. It is anticipated that all participants will have completed 12-months treatment in June 2024, and SIGNAL-AD topline data will be reported in the second half of 2024.

•

Cancer Studies. We and others have shown that SEMA4D, the target of pepinemab, is highly expressed in head and neck cancer where it impedes recruitment and activation of dendritic cells and cytotoxic T cells that can attack the tumor while also inducing differentiation of myeloid derived suppressor cells that inhibit tumoricidal immune activity. Head and neck cancer is, therefore, a cancer in which immunotherapy with pepinemab in combination with a checkpoint inhibitor such as KEYTRUDA could be uniquely effective. We have entered into a collaboration with Merck, Sharp & Dohme, who is supplying KEYTRUDA, for first-line treatment of recurrent or metastatic head and neck cancer (R/M HNSCC). Vaccinex has analyzed interim data from the first 36 patients in the open-label, single-arm, Phase 2 KEYNOTE B-84 study (NCT04815720). Study results showed that the combination therapy was well tolerated and resulted in an approximately 2X increase in objective response (ORR) and median progression free survival (PFS) in patients with hard-to-treat PD-L1-low tumors, those with combined positive score <20 (CPS<20), compared to historical response rates for checkpoint monotherapy in this population. ORR for the CPS<20 population was 21.1% with median PFS of 5.79 months, which is almost 2X that of historical response to checkpoint monotherapy in this population, ORR 11.9% and PFS 2.2 months. In contrast, the ORR and PFS for combination therapy with pepinemab in the CPS ≥20 subgroup was similar to that for historical checkpoint monotherapy. This data is consistent with a prior study in which the combination of pepinemab with PD-L1 inhibitor BAVENCIO® (avelumab) also appeared to approximately double ORR in patients with PD-L1-low non-small cell lung cancer (NCT03268057). We are also collaborating with Merck KGaA (EMD Serono in the U.S.), who is supplying Bavencio (avelumab), another checkpoint inhibitor, for combination with pepinemab in pancreatic cancer. While Pepinemab is being evaluated by third parties in investigator-sponsored trials

for breast cancer, and in multiple “window of opportunity” studies in additional cancer indications, we have currently paused our development efforts related to Cancer research as we focus on our development of Alzheimer's research.

•

Huntington’s Disease. We evaluated pepinemab for the treatment of Huntington's disease in our Phase 2 SIGNAL trial. Topline data for this trial, consisting of 265 subjects, was reported in late September 2020. Although the study did not meet its prespecified primary endpoints, it provided important new information, including evidence of cognitive benefit and a reduction in brain atrophy and increase in brain metabolic activity in patients with manifest disease symptoms. An improved study design would focus on patients with early signs of cognitive or functional deficits since they appeared to derive the greatest treatment benefit. The Company is evaluating its development strategy in terms of business opportunities and other near-term clinical activities. To advance planning for a potential phase 3 study of pepinemab in Huntington's disease, we requested a Type C meeting with the FDA to discuss details of the study design and key endpoints. The Company has received the requested clarifications regarding suitable endpoints for regulatory review from the FDA, and these will be incorporated in a possible future phase 3 study. We have currently paused our development efforts for Huntington’s disease research as we focus on our development of Alzheimer’s research.

Liquidity and Capital Resources

To date, we have not generated any revenue from product sales. Our recurring net losses and negative cash flows from operations raised substantial doubt regarding our ability to continue as a going concern within one year after the issuance of our unaudited condensed financial statements. See Note 1 of our unaudited condensed financial statements. Since our inception in 2001, we have relied on public and private sales of equity and debt financing to

fund our operations, in addition to capital contributions from noncontrolling interests and limited-service revenue from collaboration agreements.

On November 2, 2023, the Company entered into Securities Purchase Agreements with certain investors from the August and September 2023 private placements, pursuant to which the Company issued and sold 527,714 warrants to purchase up to 527,714 shares of its common stock at a purchase price of $0.125 per warrant for aggregate gross proceeds of $70,000. Vaccinex (Rochester) L.L.C., which is controlled by Maurice Zauderer, Ph.D., the Company’s president, chief executive officer and a member of its board of directors, purchased 136,752 warrants in the November Warrant Offering for a purchase price of $17,000.

During the three months ended September 30, 2023, 21,123 shares were sold through the Open Market Sale Agreement for proceeds of $0.1 million, net of commission.

In May 2023 we received $1.0 million through an award from the Alzheimer’s Drug Discovery Foundation in the form of an investment in our common stock.

On May 12, 2023, pursuant to the March 2023 Stock Purchase Agreement, we issued and sold 527,234 shares of our common stock at a purchase price of $5.6142 per share for aggregate gross proceeds of $2.96 million. FCMI purchased 447,437 shares of our common stock in May 2023 for a purchase price of $2.51 million.

On March 30, 2023, we entered into a Stock Purchase Agreement, pursuant to which we issued and sold 331,708 shares of our common stock at a purchase price of $6.15 per share for aggregate gross proceeds of $2.04 million (the "March 2023 Private Placement”). FCMI and Vaccinex (Rochester) L.L.C. purchased 325,204 shares of our common stock for aggregate purchase price of $2.0 million in the March 2023 Private Placement.

On November 18, 2022 and November 22, 2022, we entered into a stock purchase agreement and joinder thereto pursuant to which we issued and sold 476,167 shares of our common stock at a purchase price of $7.9395 per share for aggregate gross proceeds of approximately $3.8 million (the "November 2022 Private Placement"). Vaccinex (Rochester), L.L.C.; FCMI; Gee Eff Services Limited, which is controlled by Jacob Frieberg, one of our directors; and Gerald E. Van Strydonck, another of our directors, purchased 368,411 shares of our common stock for aggregate purchase price of $2.9 million in the November 2022 Private Placement.

In January 2022 we completed a private placement of 583,183 shares of our common stock and received $9.7 million and entered into an Open Market Sale Agreement with Jefferies pursuant to which we may sell up to $113.0 million shares of our common stock through Jefferies. During the year ended December 31, 2022, 212,627 shares were sold through the Open Market Sale Agreement for proceeds of $3.6 million, net of commission.

In May 2020, we received the PPP Loan in the amount of $1.1 million. During October 2021 through our intermediary lenders, the SBA communicated that it would grant forgiveness of $876,171 of the $1.1 million PPP Loan. The remaining balance of $257,429, along with applicable interest, will be amortized over the remaining term of the loan. We have extended the term of the PPP Loan to 5 years, as is currently permitted by the SBA, resulting in a maturity date of May 8, 2025. As of September 30, 2023, the remaining principal balance of the PPP Loan is approximately $119,000.

Operating Capital Requirements

Our primary uses of capital are, and we expect will continue to be, compensation and related expenses, third-party research services and amounts due to vendors for research supplies. As of September 30, 2023 and December 31, 2022, our principal source of liquidity was cash and cash equivalents in the amount of $0.1 million and $6.4 million, respectively.

Since our inception in 2001, we have incurred significant net losses and negative cash flows from operations. For the nine months ended September 30, 2023 and 2022, we reported a net loss of $16.9 million and $14.7 million, respectively. For the nine months ended September 30, 2023 and 2022, we reported cash used in operations of $13.6 million and $14.5 million, respectively. As of September 30, 2023 and December 31, 2022, we had an accumulated deficit of $336.6 million and $319.7 million, respectively. We anticipate that we will continue to generate losses for the foreseeable future, and we expect the losses to increase as we continue the development of, and seek regulatory approvals for, our product candidates. We are subject to risks associated with the development of new biopharmaceutical products, and we may encounter unforeseen expenses, difficulties, complications, delays and other unknown factors, which may adversely affect our business.

Until we can generate a sufficient amount of revenue from the commercialization of our product candidates, we expect to finance our operations through the public or private sale of equity, debt financing, or other capital sources, such as government funding, collaborations, strategic alliances, divestment of non-core assets, or licensing arrangements with third parties. We intend to use the net proceeds from our private placements, the agreements with Jefferies, and the funding we received from the Alzheimer’s Drug Discovery Foundation to fund the ongoing development of pepinemab and for working capital and general corporate purposes.

Financing strategies we may pursue include, but are not limited to, the public or private sale of equity, debt financing or funds from other capital sources, such as government funding, collaborations, strategic alliances or licensing arrangements with third parties. There can be no assurances additional capital will be available to secure additional financing, or if available, that it will be sufficient to meet our needs on favorable terms. If we are unable to raise additional capital in sufficient amounts or on terms acceptable to us, we may have to significantly delay, scale back or discontinue the development of one or more of our product candidates. If we raise additional funds through the public or private sale of equity or debt financing, it could result in dilution to our existing stockholders or increased fixed payment obligations and these securities may have rights senior to those of our common stock and could contain covenants that would restrict our operations and potentially impair our competitiveness, such as limitations on our ability to incur additional debt, limitations on our ability to acquire, sell or license our intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. Any of these events could significantly harm our business, financial condition and prospects.

Cash Flows

The following table summarizes our cash flows for the periods presented:


	Nine Months Ended September 30,
	2023			2022
	(in thousands)
Cash used in operating activities	$	(13,642	)	$	(14,475	)
Cash used in investing activities		(67	)		(101	)
Cash provided by financing activities		7,445			13,173

Operating Activities. We have historically experienced negative cash flows as we have developed our product candidates and continued to expand our business. Our net cash used in operating activities primarily results from our net loss adjusted for non-cash expenses and changes in working capital components as we have continued our research and development and is influenced by the timing of cash payments for research related expenses. Our primary uses of cash from operating activities are compensation and related expenses, employee-related expenditures, third-party research services and amounts due to vendors for research supplies. Our cash flows from operating activities will continue to be affected principally by the extent to which we increase spending on personnel, research and development and other operating activities as our business grows.

During the nine months ended September 30, 2023 and 2022, operating activities used $13.6 million and $14.5 million, respectively, in cash, primarily as a result of our continued efforts of discovery and development of targeted biotherapeutics to treat serious diseases and conditions with unmet medical needs without any product revenue, resulting in a net loss of $16.9 million and $14.7 million, respectively.

Investing Activities. The investing activities during the nine months ended September 30, 2023 and 2022, were due to purchases of property and equipment.

Financing Activities. During the nine months ended September 30, 2023, financing activities provided a net of $7.4 million, of which $6.3 million was due to private placements of common stock, $1.0 million through an award from the Alzheimer’s Drug Discovery Foundation in the form of an investment in our common stock and $0.2 million was due to the issuance of the Company’s common stock pursuant to the Open Market Sale Agreement. During the nine months ended September 30, 2022, financing activities provided a net of $13.2 million, of which $9.6 million was due to the private placement of common stock and $3.5 million was due to the issuance of the Company’s common stock pursuant to the Open Market Sale Agreement, net of underwriting commissions and discounts.

JOBS Act Accounting Election

We are an “emerging growth company” within the meaning of the Jumpstart Our Business Startups Act or the JOBS Act. Section 107(b) of the JOBS Act provides that an emerging growth company can leverage the extended transition period, provided in Section 102(b) of the JOBS Act, for complying with new or revised accounting standards. Thus, an emerging growth company can delay the adoption of new or revised accounting standards that have different effective dates for public and private companies until those standards apply to private companies. We have elected to use this extended transition period and, as a result, our condensed financial statements may not be comparable to companies that comply with public company effective dates of such accounting standards.

We will no longer be an "emerging growth company" after December 30, 2023 and will be unable to take advantage of the exemptions from various requirements applicable to public companies including those discussed above.

Critical Accounting Policies and Estimates

Our unaudited condensed financial statements are prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these condensed financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, expenses and related disclosures. We evaluate our estimates and assumptions on an ongoing basis. Our estimates are based on historical experience and various other assumptions that we believe to be reasonable under the circumstances. Our actual results could differ from these estimates.

There have been no material changes to our critical accounting policies and significant judgments as compared to the critical accounting policies and estimates disclosed in our Annual Report on Form 10-K for the year ended December 31, 2022.

Impact of Recent Accounting Pronouncements

For a discussion on the impact of recent accounting pronouncements on our business, see Note 2 to our unaudited condensed financial statements.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

As a smaller reporting company, we are not required to provide the information required by this item.

Item 4. Controls and Procedures

Evaluation of disclosure controls and procedures

Our Chief Executive Officer (our principal executive officer) and Chief Financial Officer (our principal financial officer), with the participation of our management evaluated the effectiveness of the design and operation 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 amended, or the Exchange Act, as of September 30, 2023, the end of the period covered by this Form 10-Q. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of September 30, 2023, 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 identified in connection with the evaluation required by Rules 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the quarter ended September 30, 2023 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

An investment in our stock involves a high degree of risk. You should carefully consider the risks set forth in this section, and in Part I, Item 1A of the Annual Report on Form 10-K for the fiscal year ended December 31, 2022 (the "Annual Report"), and all of the other information set forth in this Report, the Annual Report, and in the other reports we file with the SEC. If any of the risks contained in those reports actually occur, our business, results of operation, financial condition, and liquidity could be harmed, the value of our securities could decline, and you could lose all or part of your investment. Except as set forth below, there have been no material changes from risk factors disclosed in the Annual Report. See the discussion of the Company’s risk factors under Part I, Item 1A. of the Annual Report.

We are currently not in compliance with the continued listing standards of the Nasdaq Capital Market, and if we are unable to regain compliance, our common stock will be delisted from the exchange.

Our common stock is currently listed for trading on the Nasdaq Capital Market under the symbol “VCNX." The continued listing of our common stock on The Nasdaq Stock Market ("Nasdaq") is subject to our compliance with a number of listing standards.

Minimum Bid Price Requirement

On October 10, 2022, we received a letter from the Listing Qualifications Staff of Nasdaq indicating that we no longer met the requirements of Nasdaq Listing Rule 5550(a)(2), which requires listed companies to maintain a minimum bid price of at least $1.00 per share.

In accordance with Nasdaq Listing Rule 5810(c)(3)(A), the Company received a second 180-day compliance period, or until October 9, 2023 to regain compliance with the minimum bid price requirement. We did not regain compliance by October 9, 2023 and received a notice from Nasdaq that our stock is subject to delisting. We appealed the delisting notice and have received an extension until March 4, 2024 to regain compliance with the minimum bid price requirement, subject to fulfilling our commitments to regain compliance by such date. There can be no assurance that we will be able to regain compliance with the Nasdaq minimum bid price requirements or that our common stock will continue to be listed on Nasdaq.

Minimum Stockholders’ Equity Requirement

On May 25, 2023, we received a letter from the Listing Qualifications staff of Nasdaq indicating that we no longer met the requirement under Nasdaq Listing Rule 5550(b)(1) which requires listed companies to maintain a minimum of $2.5 million in stockholders’ equity for continued listing on the Nasdaq Capital Market (the “Equity Standard”) or the alternative requirements of having a market value of listed securities of $35 million or net income from continuing operations of $500,000 in the most recently completed fiscal year or two of the last three most recently completed fiscal years (the “Alternative Standards”). Nasdaq noted that our Form 10-Q for the period ended March 31, 2023 disclosed stockholders’ equity of $2.4 million as of March 31, 2023 and that, as of May 24, 2023, we did not meet the Alternative Standards.

The notification letter has no immediate effect on the Company’s listing on the Nasdaq Capital Market. Nasdaq is providing the Company 45 calendar days from the date of the notification letter, or until July 9, 2023, to submit a plan to regain compliance with the Equity Standard (the “Compliance Plan”). A plan to regain compliance was submitted on July 7, 2023 and was accepted on July 18, 2023, and therefore the Company was granted an extension of up to 180 calendar days from the date of the notification letter, or until November 21, 2023, to regain compliance with the Equity Standard. As of September 30, 2023, we had a stockholder’s deficit of $3,869 thousand and had not regained compliance with the Equity Standard. On October 3, 2023 the Company raised aggregate gross proceeds of $9.60 million in a public offering. After conducting the public offering we received a letter from Nasdaq indicating we were in compliance with Nasdaq’s Equity Standard. We anticipate we will be in compliance with the Equity Standard for the period ended December 31, 2023. However, if the Company is not found to have regained compliance, Nasdaq could provide notice that the Company’s common stock is subject to delisting. In the

event the Company receives notice that its common stock is being delisted, Nasdaq rules permit the Company to appeal any delisting determination by the Nasdaq staff to a Hearings Panel.

A delisting due to either the minimum bid price requirement or minimum stockholders' equity requirement or even notification of failure to comply with such requirements would likely have a negative effect on the price of our common stock and would impair your ability to sell or purchase our common stock when you wish to do so. In addition, the delisting of our common stock could lead to a number of other negative implications such as a loss of media and analyst coverage, a determination that our common stock is a “penny stock” which will require brokers trading in our common stock to adhere to more stringent rules and likely result in a reduced level of trading activity in the secondary trading market for our securities, and materially adversely impact our ability to raise capital on acceptable terms or at all. Delisting from Nasdaq could also have other negative results, including the potential loss of confidence by our current or prospective third-party providers and collaboration partners, the loss of institutional investor interest, and fewer licensing and partnering opportunities. In the event of a delisting, we would take actions to restore our compliance with Nasdaq’s listing requirements, but we can provide no assurance that any such action would allow our common stock to become listed again, stabilize the market price or improve the liquidity of our common stock, prevent our common stock from dropping below the Nasdaq minimum bid price requirement, prevent our stockholders' equity to fail to meet the Equity Standard or Alternative Standards, or prevent future non-compliance with Nasdaq’s listing requirements.

If our common stock were no longer listed on Nasdaq, investors might only be able to trade on one of the over-the-counter markets. There is no assurance, however, that prices for our common stock would be quoted on one of these other trading systems or that an active trading market for our common stock would exist, which would materially and adversely impact the market value of our common stock and your ability to sell our common stock.

We may need to conduct a reverse stock split to affect an increase in the price of our common stock. We cannot assure you that any reverse stock split, if approved and implemented, will increase the price of our common stock or cause us to satisfy the Nasdaq continued listing requirements.

We may need to conduct a reverse stock split to increase the price of our common stock. We cannot assure you that any reverse stock split, if approved and implemented, will increase the market price of our common stock. The effect of a reverse stock split on the market price of our common stock cannot be predicted with any certainty, and the history of reverse stock splits for other companies in our industry is varied, particularly since some investors may view a reverse stock split negatively. It is possible that the per share price of our common stock after a reverse stock split will not increase in the same proportion as the reduction in the number of outstanding shares of common stock following a reverse stock split, and a reverse stock split may not result in a per share price that would attract investors who do not trade in lower priced stocks. In addition, we cannot assure you that our common stock will be more attractive to investors. Even if we implement a reverse stock split, the market price of our common stock may decrease due to factors unrelated to the reverse stock split, including our future performance. If we seek to effect a reverse stock split and it is consummated and the trading price of our common stock declines, the percentage decline as an absolute number and as a percentage of our overall market capitalization may be greater than would occur in the absence of the reverse stock split.

We may not satisfy the Nasdaq continued listing requirements following a reverse stock split, even if it is approved and implemented.

Even if a reverse stock split is approved and implemented, we may not be able to regain compliance with the bid price requirement of the Nasdaq listing standards. If our common stock ultimately were to be delisted from Nasdaq for any reason, it could negatively impact us because it would reduce the liquidity and market price of our common stock; reduce the number of investors willing to hold or acquire our common stock; negatively impact our ability to access equity markets, issue additional securities and obtain additional financing in the future; affect our ability to provide equity incentives to our employees; and negatively impact our reputation and, as a consequence, our business.

A reverse stock split, if approved and implemented, may decrease the liquidity of our common stock and result in higher transaction costs.

The liquidity of our common stock may be negatively impacted if a reverse stock split is approved and implemented, given the reduced number of shares that would be outstanding after the reverse stock split, particularly if the stock price does not increase as a result of the reverse stock split. In addition, if a reverse stock split is implemented, it may increase the number of our stockholders who own “odd lots” of fewer than 100 shares of common stock, which may be more difficult to sell. Brokerage commissions and other costs of transactions in odd lots are generally higher than the costs of transactions of more than 100 shares or of even multiples of 100 shares of common stock. Accordingly, a reverse stock split may not achieve the desired results of increasing marketability of our common stock.
