NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. Nature of Business and Basis of Presentation

Nature of Business

Altimmune, Inc., headquartered in Gaithersburg, Maryland, United States, together with its subsidiaries (collectively, the “Company” or “Altimmune”) is a clinical stage biopharmaceutical company incorporated under the laws of the State of Delaware.

The Company is focused on developing treatments for obesity and liver diseases. The Company’s pipeline includes next generation peptide therapeutics for obesity and non-alcoholic steatohepatitis (“NASH”) (for both, pemvidutide, formerly known as ALT-801), and for chronic hepatitis B (“HepTcellTM”). Since its inception, the Company has devoted substantially all of its efforts to business planning, research and development, recruiting management and technical staff and raising capital, and has financed its operations through the issuance of common and preferred stock, long-term debt and proceeds from research grants and government contracts. The Company has not generated any revenues from the sale of any products to date, and there is no assurance of any future revenues from product sales.

Basis of Presentation

The accompanying unaudited consolidated financial statements are prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Accordingly, they do not include all of the information and disclosures required by accounting principles generally accepted in the United States (“U.S. GAAP”) for complete consolidated financial statements and should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2022 included in the Annual Report on Form 10-K which was filed with the SEC on February 28, 2023. In the opinion of management, the Company has prepared the accompanying unaudited consolidated financial statements on the same basis as the audited consolidated financial statements, and these consolidated financial statements include all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the results of the interim periods presented. The operating results for the interim periods presented are not necessarily indicative of the results expected for the full year 2023 or any future years or periods.

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

The accompanying unaudited consolidated financial statements have been prepared on the basis of continuity of operations, realization of assets, and the satisfaction of liabilities in the ordinary course of business. The financial statements do not include any adjustments relating to the recoverability and classification of recorded assets and liabilities that might be necessary should the Company be unable to continue as a going concern.

2. Summary of Significant Accounting Policies

During the six months ended June 30, 2023, there have been no significant changes to the Company’s summary of significant accounting policies contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 as filed with the SEC, except for the recently adopted accounting standard for ASU No. 2016-13 as disclosed below.

Use of Estimates

The preparation of these financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Significant estimates and assumptions made in the accompanying condensed consolidated financial statements include, but are not

6

Table of Contents

limited to, the valuation of share-based awards, income taxes, and accruals for research and development activities. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable. However, actual results could differ from those estimates and there may be changes to the Company’s estimates in future periods.

Short-term Investments

The Company’s short-term investments are comprised of U.S. Treasuries, corporate debt securities and certificates of deposit that have original maturities less than or equal to one year and are classified as available-for-sale (“AFS”) securities. Such securities are carried at estimated fair value, net of allowance for credit loss determined based on the Current Expected Credit Loss. Any unrealized holding gains or losses are reported as accumulated other comprehensive income or loss, which is a separate component of stockholders’ equity. In the event that the AFS security's fair value is below the amortized cost and (i) the Company intends to sell the AFS security and (ii) the AFS security is required to be sold before recovery of the loss, the AFS security's amortized cost base will be written down to its fair value and the loss will be recognized in the income statement. If the Company intends not to sell the AFS security and the AFS security is not required to be sold before recovery of the loss, the Company evaluates whether a portion of the unrealized loss is a result of credit loss. The portion of unrealized loss related to credit loss will be recorded as allowance for credit loss in the balance sheet with the corresponding credit loss in the income statement and the portion of unrealized loss not related to credit loss will be recognized in other comprehensive income (“OCI”). Dividend and interest income are recognized in other income when earned. The cost of securities sold is calculated using the specific identification method. The Company places all investments with government agencies, or corporate institutions whose debt is rated as investment grade. As of June 30, 2023, none of the unrealized losses on the Company’s short-term investments are a result of credit loss, and therefore, the unrealized losses were recognized in OCI.

Income Taxes

Due to a full valuation allowance, the Company did not record an income tax expense (benefit) for either of the three and six months ended June 30, 2023 or 2022. The Company calculates its quarterly income tax provision based on an estimated, annual effective tax rates applied to ordinary income (or loss) and other known items computed and recognized as they occur. The Company’s total provision is based on the United States statutory rate, increased by state and foreign taxes and reduced by a full valuation allowance on the Company’s deferred tax assets.

Recently adopted accounting pronouncements

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU No. 2016-13”). ASU No. 2016-13 requires financial assets measured at amortized cost to be presented at the net amount expected to be collected and any unrealized loss relating to available-for-sale debt securities to be recorded through an allowance for credit losses. The Company adopted this new accounting standard on January 1, 2023 using a modified retrospective method. Adoption of this update did not have a material impact on the Company’s financial statements and related disclosures.

3. Fair Value Measurements

Separate disclosure is required for assets and liabilities measured at fair value on a recurring basis from those measured at fair value on a non-recurring basis. Assets recorded at fair value on a non-recurring basis, such as property and equipment and intangible assets are recognized at fair value when they are impaired. During the six months ended June 30, 2023 and year ended December 31, 2022, the Company had no significant assets or liabilities that were measured at fair value on a non-recurring basis.

4. Operating Leases

The Company’s operating leases consist of leases for office and laboratory space in the United States, which expire in April 2025. Rent expense under the Company’s operating leases was $0.1 million and $0.3 million during the three and six months ended June 30, 2023. During the three and six months ended June 30, 2022, rent expense under the Company’s operating leases was $0.1 million and $0.2 million, respectively. Rent expense includes short-term leases and variable lease costs that are not included in the lease obligation.

At-the-Market Offerings

On February 28, 2023, the Company entered into an Equity Distribution Agreement (the “2023 Agreement”) with Evercore Group L.L.C., JMP Securities LLC and B. Riley Securities, Inc., serving as sales agents (the “Sales Agents”), with respect to an at-the-market offerings program under which the Company may offer and sell, from time to time at its sole discretion, shares of its common stock, having an aggregate offering price of up to $150.0 million (the “Shares”) through the Sales Agents (the “2023 Offering”). All Shares offered and sold in the 2023 Offering will be issued pursuant to the Company’s Registration Statement on Form S-3ASR filed with the SEC on February 28, 2023, which was declared effective immediately, the prospectus supplement relating to the 2023 Offering filed with the SEC on February 28, 2023 and any applicable additional prospectus supplements related to the 2023 Offering that form a part of the Registration Statement. The Company capitalized approximately $0.2 million of other offering costs which will offset the proceeds received from the shares sold under the 2023 Agreement. During the six months ended June 30, 2023, the Company sold 3,364,631 shares of common stock under the 2023 Agreement resulting in approximately $13.4 million in proceeds, net of $0.4 million commission and other offering costs. As of June 30, 2023, $136.2 million remained available to be sold under the 2023 Agreement. As of June 30, 2023, there was $0.2 million deferred offering costs included in prepaid expenses and other current assets on the accompanying consolidated balance sheets.

On February 25, 2021, the Company entered into an Equity Distribution Agreement (the “2021 Agreement”) with Piper Sandler & Co., Evercore Group L.L.C. and B. Riley Securities, Inc., serving as sales agents (the “2021 Sales Agents”), with respect to an at-the-market offerings program under which the Company offered and sold shares of its common stock, having an aggregate offering price of up to $125.0 million (the “2021 Shares”) through the 2021 Sales Agents (the “2021 Offering”). All 2021 Shares offered and sold in the 2021 Offering were issued pursuant to the Company’s Registration Statement on Form S-3 filed with the SEC on December 31, 2020, which was declared effective on January 11, 2021, the prospectus supplement relating to the 2021 Offering filed with the SEC on February 25, 2021 and any applicable additional prospectus supplements related to the 2021 Offering that form a part of the Registration Statement. Under the 2021 Agreement, the Company sold 10,004,869 shares of common stock resulting in approximately $121.0 million in proceeds, net of $4.0 million commission and other offering costs. As of June 30, 2023, there were no remaining shares available under the 2021 Agreement.

Public Offering

On July 16, 2020, the Company offered and sold (i) 3,369,564 shares of common stock, at a price to the public of $23.00 per share, and (ii) pre-funded warrants of the Company to purchase 1,630,436 shares of common stock at an exercise price equal to $0.0001 per share (the “Pre-Funded Warrants”), at a price to the public of $22.9999 per share of common stock underlying the Pre-Funded Warrants (equal to the public offering price per share of common stock, minus the exercise price of each Pre-Funded Warrant). The Pre-Funded Warrants are exercisable at any time, provided that each Pre-Funded Warrant holder will be prohibited from exercising such Pre-Funded Warrants into shares of the Company’s common stock if, as a result of such exercise, the holder, together with its affiliates, would own more than 4.99% of the total number of shares of the Company’s common stock then issued and outstanding, which percentage may change at the holders’ election to any other number less than or equal to 19.99% upon 61 days’ notice to the Company.

The Company has assessed the Pre-Funded Warrants for appropriate equity or liability classification and determined that the Pre-Funded Warrants are freestanding instruments that do not meet the definition of a liability pursuant to ASC 480 and do not meet the definition of a derivative pursuant to FASB Accounting Standards Codification Topic 815, Derivatives and Hedging (“ASC 815”). The Pre-Funded Warrants are indexed to the Company’s common stock and meet all other conditions for equity classification under ASC 480 and ASC 815. Accordingly, the Pre-Funded Warrants were classified as equity and are accounted for as a component of additional paid-in capital at the time of issuance. On January 24, 2022, 760,870 of the Pre-Funded Warrants were exercised, resulting in the issuance of 760,870 shares of common stock. As of June 30, 2023, there were 869,566 remaining Pre-Funded Warrants unexercised.

As of June 30, 2023, including the remaining 869,566 Pre-Funded Warrants, there were 1,015,166 outstanding warrants with a weighted-average exercise price of $0.66 and weighted-average contractual term of 0.4 years.

9. Net Loss Per Share

Because the Company has reported a net loss attributable to common stockholders for the six months ended June 30, 2023 and 2022, basic and diluted net loss per share attributable to common stockholders in each period are the same.

Basic net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted average numbers of shares of common stock outstanding for the period. Basic

11

Table of Contents

shares outstanding includes the weighted average effect of the Company’s outstanding pre-funded warrants, the exercise of which requires little or no consideration for the delivery of shares of common stock.

Diluted net loss per share is calculated by adjusting weighted average shares outstanding for the dilutive effect of common stock equivalents outstanding for the period. As such, all unvested restricted stock, RSUs, common stock warrants, and stock options have been excluded from the computation of diluted weighted average shares outstanding because such securities would have an anti-dilutive impact for all periods presented.

Potential common shares issuable upon conversion, vesting or exercise of unvested restricted stock, RSUs, common stock warrants, and stock options that are excluded from the computation of diluted weighted-average shares outstanding, as they are anti-dilutive, are as follows:

Overview

Altimmune, Inc. is a clinical stage biopharmaceutical company focused on developing treatments for obesity and liver diseases. Our lead product candidate, pemvidutide (formerly known as ALT-801), is a GLP-1/glucagon dual receptor agonist that is being developed for the treatment of obesity and non-alcoholic steatohepatitis (“NASH”). In addition, we are developing HepTcell, an immunotherapeutic agent designed to achieve a functional cure for chronic hepatitis B. Except where the context indicates otherwise, references to “we,” “us,” “our,” “Altimmune” or the “Company” refer to the company and its subsidiaries.

Recent Business Update

Pemvidutide

On August 1, 2023 we announced that we enrolled the first subject in the Phase 2b IMPACT trial evaluating the safety and efficacy of pemvidutide in subjects with NASH. The biopsy-driven trial is expected to enroll approximately 190 subjects with and without diabetes randomized 1:2:2 to receive either 1.2 mg, 1.8 mg pemvidutide or placebo weekly for 48 weeks. The key efficacy endpoints are NASH resolution and fibrosis improvement after 24 weeks of treatment, with subjects followed for an additional 24 weeks to a total of 48 weeks for assessment of safety and additional biomarker responses. Top-line results from this trial are expected in the first quarter of 2025.

On March 21, 2023 we announced the topline results from a Week 24 interim analysis of 160 subjects in our 48-week MOMENTUM Phase 2 obesity trial of pemvidutide. The MOMENTUM Phase 2 obesity trial is being conducted at 30 sites across the U.S., designed to enroll approximately 320 subjects with subjects randomized 1:1:1:1 to 1.2 mg, 1.8 mg, 2.4 mg pemvidutide or placebo administered weekly for 48 weeks in conjunction with diet and exercise. A pre-specified interim analysis was conducted after 160 subjects completed 24 weeks of treatment.

13

Table of Contents

At Week 24, subjects receiving pemvidutide achieved mean weight losses of 7.3%, 9.4% and 10.7% at the 1.2 mg, 1.8 mg, and 2.4 mg doses, respectively, with the placebo group experiencing a mean weight loss of 1.0% (efficacy estimand using a mixed model of repeated measures (“MMRM”) analysis). Approximately 50% of subjects achieved 10% or more weight loss and approximately 20% of subjects achieved 15% or more weight loss at Week 24 at the 1.8 mg and 2.4 mg doses. Robust reductions in waist circumference (a measure of visceral fat) and serum lipids were also observed, and clinically meaningful reductions in blood pressure were achieved without clinically significant increases in heart rate.

On March 21, 2023, we also announced the results of the 12-week Phase 1b safety trial of pemvidutide in subjects with type 2 diabetes. The Phase 1b trial, which was conducted to evaluate the safety profile of pemvidutide in overweight and obese subjects with type 2 diabetes, was comprised of 54 subjects randomized 1:1:1:1 to 1.2 mg, 1.8 mg, 2.4 mg pemvidutide or placebo administered weekly for 12 weeks.

Subjects receiving pemvidutide achieved mean weight losses of 4.4%, 6.1% and 7.7% at the 1.2 mg, 1.8 mg, and 2.4 mg doses, respectively, over only 12 weeks of treatment, with the placebo group experiencing a mean weight gain of 0.8% (efficacy estimand using MMRM analysis).

HepTcell

On April 11, 2023, we announced the completion of enrollment in our Phase 2 clinical trial of HepTcell, an immunotherapeutic for the treatment of chronic hepatitis B (“CHB”). With the achievement of this milestone, data readout is planned for the first quarter of 2024.

The multicenter clinical trial, which is being conducted at 26 sites in North America, Europe and Southeast Asia, enrolled approximately 80 subjects with inactive CHB and low levels of hepatitis B surface antigen (“HBsAg”). Subjects were randomized 1:1 to HepTcell or placebo. The primary endpoint of the trial is clinical response, defined as a 1-log or greater reduction or clearance in HBsAg. Secondary endpoints include changes in the levels of hepatitis B virus (“HBV”) DNA, pre-genomic RNA and other markers of virologic response.

Revenue

We have not generated any revenues from the sale of any products to date. Our revenue in previous years consisted primarily of government and foundation grants and contracts that supported our efforts on specific research projects.

Research and development expenses

Research and development expense decreased by $2.7 million, or 17%, for the three months ended June 30, 2023, as compared to the three months ended June 30, 2022. The decrease was primarily the result of:

a decrease of $3.1 million due to the development activities for pemvidutide primarily due to the NAFLD trials, which were ongoing during the three months ended June 30, 2022 and which substantially completed by March 31, 2023, offset by startup costs related to the IMPACT Phase 2b trial in NASH;
a decrease of $1.9 million due to change in the three months ended June 30, 2022 of the fair value of contingent consideration liability with respect to the acquisition of pemvidutide, which was fully paid on June 10, 2022;
an increase of $0.4 million due to development activities for HepTcell; and
a net increase of $1.8 million due primarily to costs associated with non-project specific research and development costs such as employee compensation including stock compensation, contractors and electronic document management system (“EDMS”) implementation and service costs.

General and administrative expenses

General and administrative expense increased by $0.4 million, or 8% for the three months ended June 30, 2023, as compared to the three months ended June 30, 2022, primarily due to increase in stock compensation and other labor related expense.

Total other income (expense), net

Total other income (expense), net increased by $1.7 million or 576%, for the three months ended June 30, 2023, as compared to the three months ended June 30, 2022, primarily due to increase in interest income earned on our cash equivalents and short-term investments.

Revenue

We have not generated any revenues from the sale of any products to date. Our revenue in previous years consisted primarily of government and foundation grants and contracts that supported our efforts on specific research projects. We are closing out one of the remaining such contracts and any revenue reported during the six months ended June 30, 2023 and 2022 were for indirect rate adjustments.

Research and development expenses

Research and development expense decreased by $0.6 million, or 2%, for the six months ended June 30, 2023, as compared to the six months ended June 30, 2022. The decrease was primarily the result of:

a decrease of $4.5 million due to the development activities for pemvidutide primarily due to the NAFLD trials, which were ongoing during the six months ended June 30, 2022 and which substantially completed by March 31, 2023, offset by startup costs related to the IMPACT Phase 2b trial in NASH; and
a net increase of $3.6 million due primarily to costs associated with non-project specific research and development costs such as employee compensation including stock compensation, contractors and EDMS implementation and service costs.

General and administrative expenses

General and administrative expense increased by $0.5 million, or 5% for the six months ended June 30, 2023, as compared to the six months ended June 30, 2022, primarily due to a $0.7 million increase in stock compensation and other labor related expense.

Total other income (expense), net

Total other income (expense), net increased by $3.3 million or 917%, for the six months ended June 30, 2023, as compared to the six months ended June 30, 2022, primarily due to increase in interest income earned on our cash equivalents and short-term investments.

Our primary sources of cash during the six months ended June 30, 2023 were from equity transactions, interest and dividends from our money market funds and short-term investments, and proceeds from maturity of our short-term investments. Our cash, cash equivalents, restricted cash and short-term investments were $160.0 million as of June 30, 2023. We believe, based on the operating cash requirements and capital expenditures expected for 2023 and 2024, our cash on hand as of June 30, 2023, together with expected cash receipts from our income tax refunds and R&D incentives, are sufficient to fund operations for at least a twelve-month period from the issuance date of our June 30, 2023 consolidated financial statements.

We have not generated any revenues from the sale of any products to date, and there is no assurance of any future revenues from product sales. In the past, our sources of revenue have consisted of grant revenues under our arrangements with BARDA for the development of NasoShield, MTEC for a clinical trial and development work on T-COVID, and to a lesser degree from other licensing arrangements. The MTEC contract was closed out in June 2021 and we are currently closing out the BARDA contract which was not renewed after December 31, 2021. We have incurred significant losses since we commenced operations. As of June 30, 2023, we had an accumulated deficit of $414.0 million. In addition, we have not generated positive cash flows from operations. We have had to rely on a variety of financing sources, including the issuance of debt and equity securities. As capital resources are consumed to fund our research and development activities, we may require additional capital beyond our currently anticipated amounts. In order to address our capital

needs, including our planned clinical trials, we must continue to actively pursue additional equity or debt financing, government funding, and monetization of our existing programs through partnership arrangements or sales to third parties.

Sources of Liquidity

Public Offering

On July 16, 2020, we offered and sold (i) 3,369,564 shares of our common stock, at a price to the public of $23.00 per share, and (ii) Pre-Funded Warrants, at a price to the public of $22.9999 per share of common stock underlying the Pre-Funded Warrants (equal to the public offering price per share of common stock, minus the exercise price of each Pre-Funded Warrant). The Pre-Funded Warrants are exercisable at any time, provided that each Pre-Funded Warrant holder will be prohibited from exercising such Pre-Funded Warrants into shares of our common stock if, as a result of such exercise, the holder, together with its affiliates, would own more than 4.99% of the total number of shares of our common stock then issued and outstanding, which percentage may change at the holders’ election to any other number less than or equal to 19.99% upon 61 days’ notice to us. The gross proceeds of this offering were approximately $132.2 million, which includes the exercise in full of the underwriters’ option to purchase an additional 750,000 shares of common stock, before deducting underwriting discounts and commissions and offering expenses during the third quarter of 2020. The net proceeds of this offering were approximately $124.0 million, after deducting underwriting discounts and commissions and offering expenses payable by us. On January 24, 2022, 760,870 of the Pre-Funded Warrants were exercised, resulting in the issuance of 760,870 shares of common stock. As of June 30, 2023, there were 869,566 remaining Pre-Funded Warrants unexercised.

Shelf Registrations

On February 28, 2023, we filed a shelf registration statement on Form S-3ASR, which was declared effective immediately. This shelf registration allows us to offer and sell any amount of our common stock, preferred stock, debt securities, warrants, rights and units (the “2023 Shelf”) for a period of 3 years from effectiveness or until such determination that we no longer qualify as a well-known seasoned issuer.

On December 31, 2020, we filed a shelf registration statement on Form S-3, which was declared effective by the SEC on January 11, 2021. This shelf registration statement covered the offering, issuance and sale by us of up to an aggregate of $250.0 million of our common stock, preferred stock, debt securities, warrants, rights and units (the “2021 Shelf”).

At-the-Market Offerings

On February 28, 2023, we entered an Equity Distribution Agreement (“the 2023 Agreement”) with Evercore Group L.L.C., JMP Securities LLC and B. Riley Securities, Inc., serving as sales agents, with respect to an at-the-market offerings program under which we may offer and sell, from time to time at our sole discretion, shares of our common stock, having an aggregate offering price of up to $150.0 million. During the six months ended June 30, 2023, we sold 3,364,631 shares of common stock under the 2023 Agreement resulting in approximately $13.4 million in net proceeds, and as of June 30, 2023, $136.2 million remained available to be sold under the 2023 Shelf.

On February 25, 2021, we entered into an Equity Distribution Agreement (the “2021 Agreement”) with Piper Sandler & Co., Evercore Group L.L.C. and B. Riley Securities, Inc., serving as sales agents, with respect to an at-the-market offerings program under which we offered and sold shares of our common stock, having an aggregate offering price of up to $125.0 million. Under the 2021 Agreement, we sold 10,004,869 shares of common stock resulting in approximately $121.0 million in proceeds, net of $4.0 million commission and other offering costs. As of June 30, 2023, there were no remaining 2021 Shares available under the 2021 Agreement.

Operating Activities

Net cash used in operating activities was $38.8 million for the six months ended June 30, 2023 compared to $30.2 million during the six months ended June 30, 2022. The primary uses of cash from our operating activities include payments for labor and labor-related costs, professional fees, research and development costs associated with our clinical trials and other general corporate expenditures. The increase in cash used in operations of $8.6 million year over year is due to changes in working capital accounts of $12.2 million, partially offset by an increase in net loss as adjusted for non-cash items of $3.7 million.

Investing Activities

Net cash provided by investing activities was $17.3 million for the six months ended June 30, 2023 compared to $49.0 million net cash used in during the six months ended June 30, 2022. The net cash provided by investing activities during the six months ended June 30, 2023 was primarily due to $60.6 million proceeds from sale and maturities of short-term investments, partially offset by $43.2 million purchase of short-term investments. The net cash used in investing activities during the six months ended June 30, 2022 was primarily due to $48.9 million purchase of short-term investments.

Financing Activities

Net cash provided by financing activities during the six months ended June 30, 2023 was $12.8 million compared to $24.8 million for the six months ended June 30, 2022. The net cash provided by financing activities during the six months ended June 30, 2023 was primarily the result of the receipt of $13.2 million in net proceeds from the issuance of common stock from our at-the-market offerings program, partially offset by $0.5 million payment for tax withholding obligations related to share-based compensation. The net cash provided by financing activities during the six months ended June 30, 2022 was primarily the result of the receipt of $24.3 million in proceeds from the issuance of common stock from our at-the-market offerings program and $0.6 million in proceeds from exercise of stock options, partially offset by $0.3 million payment for tax withholding obligations related to share-based compensation.

Current Resources

We have financed our operations to date principally through our equity offerings and proceeds from issuances of our preferred stock, common stock and warrants. As of June 30, 2023, we had $102.4 million of cash, cash equivalents and restricted cash and $57.6 million of short-term investments. Accordingly, management believes that we have sufficient capital to fund our plan of operations for at least a twelve-month period from the issuance date of our June 30, 2023 financial statements. However, in order to address our capital needs in the long-term, including our planned clinical trials, we must continue to actively pursue additional equity or debt financing, government funding, and monetization of our existing programs through partnership arrangements or sales to third parties.

Critical Accounting Estimates

Management’s Discussion and Analysis of Financial Condition and Results of Operations is based upon our unaudited consolidated financial statements, which have been prepared in accordance with U.S. GAAP and the rules and regulations of the SEC for interim financial reporting. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, expenses, and the disclosure of contingent liabilities in our consolidated financial statements. We base our estimates and judgments on historical experience, knowledge of current conditions, and expectations of what could occur in the future given available information.

There have been no changes in our critical accounting policies and significant judgment and estimates as disclosed in our Annual Report on Form 10-K for the year ended December 31, 2022, except for the recently adopted accounting standard for ASU No. 2016-13 as disclosed in Note 2. For more information regarding our critical accounting policies, we encourage you to read the discussion contained in Item 7 under the heading “Critical Accounting Estimates” and Note 2 “Summary of Significant Accounting Policies” included in the notes to the consolidated financial statements contained in our Annual Report on Form 10-K for the year ended December 31, 2022.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures pursuant to Rule 13a-15 under the Securities Exchange Act of 1934, as amended (“the “Exchange Act”) as of the end of the period covered by this Quarterly Report on Form 10-Q.

Based on this evaluation, our principal executive officer and principal financial officer concluded that, as of June 30, 2023, our disclosure controls and procedures were effective to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) and Rule 15d-15(f) under the Exchange Act) during the quarter ended June 30, 2023 identified in connection with the evaluation thereof by our management, including the Chief Executive Officer and Chief Financial Officer, that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
