Notes to the Condensed Consolidated Financial Statements (Unaudited)

NOTE 1. Organization and Basis of Presentation

General

Vaxart Biosciences, Inc. was originally incorporated in California in March 2004, under the name West Coast Biologicals, Inc. The Company changed its name to Vaxart, Inc. (“Private Vaxart”) in July 2007, and reincorporated in the state of Delaware.

On February 13, 2018, Private Vaxart completed a business combination with Aviragen Therapeutics, Inc. (“Aviragen”), pursuant to which Aviragen merged with Private Vaxart, with Private Vaxart surviving as a wholly owned subsidiary of Aviragen (the “Merger”). Pursuant to the terms of the Merger, Aviragen changed its name to Vaxart, Inc. (together with its subsidiaries, the “Company” or “Vaxart”) and Private Vaxart changed its name to Vaxart Biosciences, Inc.

On June 8, 2020, the Company’s shareholders approved an amendment to the Company’s certificate of incorporation to change the par value of its common and preferred stock from $0.10 per share to $0.0001 per share and to increase the number of authorized shares of common stock from 100,000,000 to 150,000,000. Except as otherwise noted in these condensed consolidated financial statements, all share, equity security and per share amounts are presented to give retroactive effect to these changes.

On October 13, 2020, the Company entered into the Open Market Sale Agreement, (the “October 2020 ATM”) pursuant to which it could offer and sell, from time to time through sales agents, shares of its common stock having an aggregate offering price of up to $250 million. The Company incurred direct expenses of approximately $0.3 million in connection with filing a prospectus supplement, dated October 13, 2020, with the U.S. Securities and Exchange Commission (the “SEC”), and paid sales commissions of up to 4.5% of gross proceeds from the sale of shares. As of December 31, 2020, the Company had sold 692,651 shares for gross proceeds of $5.5 million which, after deducting sales commissions and expenses, resulted in net proceeds under the October 2020 ATM of $4.9 million in 2020.

In the nine months ended September 30, 2021, the Company sold an additional 13,239,839 shares under the October 2020 ATM for gross proceeds of $127.9 million which, after deducting sales commissions and expenses, resulted in net proceeds under the October 2020 ATM of $122.2 million. As of September 30, 2021, a total of 13,932,490 shares had been issued and sold under the October 2020 ATM since its inception for gross proceeds of $133.4 million which, after deducting sales commissions and expenses, resulted in net proceeds of $127.1 million.

On September 13, 2021, the October 2020 ATM was terminated and on September 15, 2021, the Company entered into a Controlled Equity Offering Sales Agreement (the “September 2021 ATM”), pursuant to which it may offer and sell, from time to time through sales agents, shares of its common stock having an aggregate offering price of up to $100 million. The Company incurred direct expenses of approximately $0.2 million in connection with filing a prospectus supplement with the SEC on September 16, 2021, and will pay sales commissions of up to 3.0% of gross proceeds from the sale of shares. As of September 30, 2021, no shares had been issued under the September 2021 ATM.

The Company’s principal operations are based in South San Francisco, California, and it operates in one reportable segment, which is the discovery and development of oral recombinant protein vaccines, based on its proprietary oral vaccine platform.

NOTE 2. Summary of Significant Accounting Policies

Basis of Presentation – The Company has prepared the accompanying condensed consolidated financial statements pursuant to the rules and regulations of the SEC. Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been condensed or omitted pursuant to these rules and regulations. These condensed consolidated financial statements should be read in conjunction with the Company’s audited financial statements and footnotes related thereto for the year ended December 31, 2020, included in the Company’s Annual Report on Form 10-K filed with the SEC on February 25, 2021 (the “Annual Report”). Unless noted below, there have been no material changes to the Company’s significant accounting policies described in Note 2 to the consolidated financial statements included in the Annual Report. In the opinion of management, the unaudited condensed consolidated financial statements include all adjustments (consisting only of normal recurring adjustments) necessary to present fairly the Company’s financial position and the results of its operations and cash flows. The results of operations for such interim periods are not necessarily indicative of the results to be expected for the full year or any future periods.

VAXART, INC.

Notes to the Condensed Consolidated Financial Statements (Unaudited)

Basis of Consolidation – The condensed consolidated financial statements include the financial statements of Vaxart, Inc. and its subsidiaries. All significant transactions and balances between Vaxart, Inc. and its subsidiaries have been eliminated in consolidation.

Use of Estimates – 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, liabilities, revenues and expenses and disclosure of contingent assets and liabilities in the financial statements and accompanying notes. Actual results and outcomes could differ from these estimates and assumptions.

Investments – Excess cash balances may be invested in marketable debt securities. All investments that are readily convertible to known amounts of cash with stated maturities greater than three months when purchased are classified as investments.

The Company determines the appropriate classification of its investments in marketable securities at the time of purchase and reevaluates such designation at each balance sheet date. Marketable debt securities are classified and accounted for as available-for-sale. After consideration of the Company’s objectives to preserve capital, as well as its liquidity requirements, it may sell these debt securities prior to their stated maturities. These securities are carried at fair value and unrealized gains and losses, net of taxes, are reported as a component of stockholders’ equity, except for unrealized losses determined to be other-than-temporary, which are recorded within other income and (expenses). Any realized gains or losses on the sale of marketable debt securities are determined on a specific identification method, and such gains and losses are recorded as a component of other income and (expenses). Available-for-sale investments are classified as either current or non-current assets based on each instrument’s underlying effective maturity date and whether the Company has the intent and ability to hold the investment for a period of greater than 12 months. Marketable securities with remaining maturities of 12 months or less are classified as current and are reported as short-term investments in the condensed consolidated balance sheets. Marketable securities with remaining maturities of more than 12 months for which the Company has the intent and ability to hold the investment for more than 12 months are classified as non-current and are included in long-term investments in the condensed consolidated balance sheets.

Securities are evaluated for impairment at the end of each reporting period. Impairment is evaluated considering numerous factors, including whether a decline in fair value below the amortized cost basis is due to credit-related factors or non-credit-related factors, the financial condition and near-term prospects of the issuer, and intent and ability to hold the investment to allow for an anticipated recovery in fair value. A credit-related impairment is recognized as an allowance on the balance sheet with a corresponding adjustment to earnings. Any impairment that is not credit-related is recognized in other comprehensive loss, net of applicable taxes.

Concentration of Credit Risk – Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash, cash equivalents and available-for-sale investments. The Company places its cash, cash equivalents and available-for-sale investments at financial institutions that management believes are of high credit quality. The Company is exposed to credit risk in the event of default by the financial institutions holding the cash and cash equivalents to the extent such amounts are in excess of the federally insured limits. The Company has not experienced any losses on its deposits since inception.

The primary focus of the Company’s investment strategy is to preserve capital and meet liquidity requirements. The Company’s investment policy addresses the level of credit exposure by limiting the concentration in any one corporate issuer or sector and establishing a minimum allowable credit rating.

Recent Accounting Pronouncements

In August 2020, the FASB issued Accounting Standards Update (ASU) 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in an Entity’s Own Equity (Subtopic 815-40). In addition to simplifying the accounting for certain debt and equity instruments, none of which the Company presently has outstanding, this standard update provides guidance on how certain instruments should be treated in the computation of earnings per share. The Company adopted the new guidance effective January 1, 2021, using the modified retrospective method. Its adoption had an immaterial impact on the number of shares used in the computation of year-to-date basic and diluted earnings per share.

The Company has reviewed all other significant newly-issued accounting pronouncements that are not yet effective and concluded that they are either not applicable to its operations or their adoption is not expected to have a material impact on its financial position or results of operations.

NOTE 3. Fair Value of Financial Instruments

Fair value accounting is applied for all financial assets and liabilities and nonfinancial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually). Financial instruments include cash and cash equivalents, marketable securities, accounts receivable, accounts payable and accrued liabilities that approximate fair value due to their relatively short maturities.

Assets and liabilities recorded at fair value on a recurring basis in the balance sheets are categorized based upon the level of judgment associated with inputs used to measure their fair values. The accounting guidance for fair value provides a framework for measuring fair value and requires certain disclosures about how fair value is determined. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the reporting date. The accounting guidance also establishes a three-level valuation hierarchy that prioritizes the inputs to valuation techniques used to measure fair value based upon whether such inputs are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect market assumptions made by the reporting entity.

The three-level hierarchy for the inputs to valuation techniques is briefly summarized as follows:

Level 1 – Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date;

Level 2 – Inputs are observable, unadjusted quoted prices in active markets for similar assets or liabilities, unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the related assets or liabilities; and

Level 3 – Unobservable inputs that are significant to the measurement of the fair value of the assets or liabilities that are supported by little or no market data.

The following table sets forth the fair value of the Company’s financial assets that are measured on a recurring basis as of September 30, 2021 and December 31, 2020 (in thousands):

	*Level 1*		*Level 2*		*Level 3*		*Total*

Royalty Agreements

Aviragen entered into a royalty-generating research and license agreement with GlaxoSmithKline, plc (“GSK”) in 1990 for the development and commercialization of zanamivir, a neuraminidase inhibitor marketed by GSK as Relenza, to treat influenza. All of the Company’s Relenza patents have expired, with the last remaining patent expiring in July 2019 in Japan, at which time royalty revenue ceased, although until April 30, 2020, it remained subject to adjustments for sales returns and exchange rate differences. There was no royalty revenue related to Relenza recognized in the nine months ended September 30, 2021, and in the nine months ended September 30, 2020, the Company recognized revenue of $193,000, all in the three months ended June 30, 2020.

The Company also generates royalty revenue from the sale of Inavir in Japan, pursuant to a collaboration and license agreement that Aviragen entered into with Daiichi Sankyo Company, Limited (“Daiichi Sankyo”) in 2009. In September 2010, laninamivir octanoate was approved for sale by the Japanese Ministry of Health and Welfare for the treatment of influenza in adults and children, which Daiichi Sankyo markets as Inavir. Under the agreement, the Company currently receives a 4% royalty on net sales of Inavir in Japan. The last patent related to Inavir is set to expire in December 2029, at which time royalty revenue will cease. The royalty revenue related to Inavirrecognized in the nine months ended September 30, 2021 and 2020, was nil and $2.8 million, respectively. In addition, the Company recognized non-cash royalty revenue related to the sale of future royalties (see Note 6) of $200,000 and $263,000 in the three months ended September 30, 2021 and 2020, respectively, and $805,000 and $535,000 in the nine months ended September 30, 2021 and 2020, respectively. Both the royalty revenue and the non-cash royalty revenue related to sale of future royalties have been subjected to a 5% withholding tax in Japan, for which $10,000 and $13,000 was included in income tax expense in the three months ended September 30, 2021 and 2020, respectively, and $40,000 and $165,000 was included in income tax expense in the nine months ended September 30, 2021 and 2020, respectively.

The Company’s royalty revenue is seasonal, in line with the flu season, so the majority of the Company’s royalty revenue is earned in the first and fourth fiscal quarters.

NOTE 6. Liabilities Related to Sale of Future Royalties

In April 2016, Aviragen entered into a Royalty Interest Acquisition Agreement (the “RIAA”) with HealthCare Royalty Partners III, L.P. (“HCRP”). Under the RIAA, HCRP made a $20.0 million cash payment to Aviragen in consideration for acquiring certain royalty rights (“Royalty Rights”) related to the approved product Inavir in the Japanese market. The Royalty Rights were obtained pursuant to the collaboration and license agreements (the “License Agreement”) and a commercialization agreement that the Company entered into with Daiichi Sankyo. Per the terms of the RIAA, HCRP is entitled to the first $3.0 million plus 15% of the next $1.0 million in royalties earned in each year commencing on April 1, with any excess revenue being retained by the Company.

Under the relevant accounting guidance, due to a limit on the amount of royalties that HCRP can earn under the RIAA, this transaction is accounted for as a liability that is being amortized using the interest method over the life of the arrangement. The Company has no obligation to pay any amounts to HCRP other than to pass through to HCRP its share of royalties as they are received from Daiichi Sankyo. In order to record the amortization of the liability, the Company is required to estimate the total amount of future royalty payments to be received under the License Agreement and the payments that will be passed through to HCRP over the life of this agreement. Consequently, the Company imputes interest on the unamortized portion of the liability and records non-cash interest expense using an estimated effective interest rate. The royalties earned in each period that will be passed through to HCRP are recorded as non-cash royalty revenue related to sale of future royalties, with any excess not subject to pass-through being recorded as royalty revenue. When the pass-through royalties are paid to HCRP in the following quarter, the imputed liability related to sale of future royalties is commensurately reduced. The Company periodically assesses the expected royalty payments, and to the extent such payments are greater or less than the initial estimate, the Company adjusts the amortization of the liability and interest rate. As a result of this accounting, even though the Company does not retain HCRP’s share of the royalties, it will continue to record non-cash revenue related to those royalties until the amount of the associated liability, including the related interest, is fully amortized.

The following table shows the activity within the liability account during the nine months ended September 30, 2021 (in thousands):

Total liability related to sale of future royalties, start of period	$	14,929
Non-cash royalty revenue paid to HCRP		(908	)
Non-cash interest expense recognized		1,137
Total liability related to sale of future royalties, end of period		15,158
Current portion		(3,118	)

NOTE 7. Leases

The Company has the right of use for office and manufacturing facilities under five operating lease agreements with initial terms exceeding one year, and has two operating lease agreements for manufacturing facilities and one for manufacturing equipment with initial terms of one year or less.

The Company obtained the right of use of real estate located in South San Francisco, California, in November 2020 under a lease that was scheduled to terminate on September 30, 2025, which has been extended until March 31, 2029, with no extension option. The Company also obtained the right of use of real estate located in South San Francisco, California, in June 2015 that was scheduled to terminate on April 30, 2020, with a five-year extension option that the Company exercised in July 2019, extending the lease until April 30, 2025, which has been extended until March 31, 2029, with an option to extend for an additional eight years. Further, the Company obtained, via the Merger in February 2018, the right of use of facilities located in Alpharetta, Georgia, that terminated on February 28, 2021, with no extension option. These facilities were subleased for the remainder of the lease term effective November 30, 2018. In addition, the Company has the right of use of a facility located in South San Francisco, California, under a lease that, following a one-year extension, now terminates on July 31, 2022, with no extension option. Further, the Company has the right of use of a facility located in South San Francisco, California, under a lease that terminates on March 30, 2029, with a five-year renewal option. The Company has also identified an embedded lease for the rental of facilities in Burlingame, California, within a Statement of Work for the manufacture of bulk vaccine product that is expected to be completed in 2022, and short-term embedded leases for the rental of facilities in South San Francisco, California and Lodi, Wisconsin.

As of September 30, 2021, the weighted average discount rate for operating leases with initial terms of more than one year was 9.26% and the weighted average remaining term of these leases was 7.17 years. Discount rates were determined using the Company’s marginal rate of borrowing at the time each lease commenced or was extended.

The following table summarizes the Company’s undiscounted cash payment obligations for its operating lease liabilities with initial terms of more than twelve months as of September 30, 2021 (in thousands):

Year Ending December 31,
2021 (three months remaining)	$	556
2022		2,256

NOTE 8. Commitments and Contingencies

(a)

Purchase Commitments

As of September 30, 2021, the Company had approximately $18.2 million of non-cancelable purchase commitments, principally for contract manufacturing and clinical services which are expected to be paid within the next year. In addition, the Company has operating lease commitments as detailed in Note 7 and a further commitment for an operating lease with rental payments totaling $14.9 million payable by March 31, 2029, which has been executed but has not yet commenced.

(b)

Indemnifications

In the ordinary course of business, the Company enters into agreements that may include indemnification provisions. Pursuant to such agreements, the Company may indemnify, hold harmless and defend indemnified parties for losses suffered or incurred by the indemnified party. Some of the provisions will limit losses to those arising from third-party actions. In some cases, the indemnification will continue after the termination of the agreement. The maximum potential amount of future payments the Company could be required to make under these provisions is not determinable. The Company has also entered into indemnification agreements with its directors and officers that require the Company to indemnify its directors and officers against liabilities that may arise by reason of their status or service as directors or officers to the fullest extent permitted by Delaware corporate law. The Company currently has directors’ and officers’ insurance.

(c)

Litigation

From time to time the Company may be involved in legal proceedings arising in connection with its business. Based on information currently available, the Company believes that the amount, or range, of reasonably possible losses in connection with any pending actions against it in excess of established reserves, in the aggregate, is not material to its consolidated financial condition or cash flows. However, any current or future dispute resolution or legal proceeding, regardless of the merits of any such proceeding, could result in substantial costs and a diversion of management’s attention and resources that are needed to run the Company successfully, and could have a material adverse impact on its business, financial condition and results of operations.

On August 4, 2020, a purported shareholder derivative complaint was filed in the Superior Court of California, San Mateo County, entitled Godfrey v. Latour, et al. An amended complaint was filed on September 4, 2020, and the case was re-named Ennis v. Latour, et al. A second amended complaint was filed on November 25, 2020. On March 15, 2021, the court sustained demurrers to the second amended complaint, without prejudice to file a further amended complaint. A third amended complaint was filed on June 11, 2021. The third amended complaint names certain current and former Vaxart directors as defendants, asserting claims against them for breach of fiduciary duty, unjust enrichment, and waste and seeking, among other things, an award of unspecified damages, certain equitable relief, and attorneys’ fees and costs. The complaint also asserts claims for breach of fiduciary duty and aiding and abetting breach of fiduciary duty against Armistice Capital, LLC (“Armistice”). The complaint challenges certain stock options granted to certain of the Company’s officers and directors between March 24, 2020 and June 15, 2020; certain alleged statements and omissions made in the Company’s April 24, 2020 proxy statement; and certain amendments to two warrants held by Armistice, as disclosed on June 8, 2020. The third amended complaint purports to bring the lawsuit derivatively on behalf of and for the benefit of the Company and names the Company as a “nominal defendant” against which no damages are sought. On August 31, 2021, all defendants filed their respective demurrers to the third amended complaint, which remains pending.

On September 8, 2020, a purported shareholder derivative complaint was filed in the Court of Chancery of the State of Delaware, entitled Galjour v. Floroiu, et al. On October 20, 2020, a purported shareholder derivative and class action complaint, entitled Jaquith v. Vaxart, Inc., was filed in the Court of Chancery of the State of Delaware. On November 12, 2020, the two actions were consolidated under the caption In re Vaxart, Inc. Stockholder Litigation and the complaint filed in the Jaquith action was deemed the operative pleading. The operative complaint names as defendants certain current and former Vaxart directors, asserting claims against them for breach of fiduciary duty and unjust enrichment and seeking, among other things, an award of unspecified damages, certain equitable relief, and attorneys’ fees and costs. The complaint also asserts claims for unjust enrichment and breach of fiduciary duty or alternatively aiding and abetting breach of fiduciary duty against Armistice. The complaint challenges certain stock options granted to certain of the Company’s officers and directors between March 24, 2020 and June 15, 2020; certain alleged statements and omissions made in the Company’s April 24, 2020 proxy statement; and certain amendments to two warrants held by Armistice, as disclosed on June 8, 2020. The complaint purports to bring all but one of the claims derivatively on behalf of and for the benefit of the Company. It also purports to bring one claim, for breach of fiduciary duty based on alleged statements and omissions in the Company’s April 24, 2020 proxy statement, directly on behalf of a class of Vaxart stockholders. The complaint names the Company as a “nominal defendant” against which no damages are sought. On January 4, 2021, all defendants filed motions to dismiss. These motions are pending.

In August and September 2020, two substantially similar securities class actions were filed in the U.S. District Court for the Northern District of California. The first, entitled Himmelberg v. Vaxart, Inc. et al. was filed on August 24, 2020. The second action, entitled Hovhannisyan v. Vaxart, Inc. et al. was filed on September 1, 2020 (together, the “Putative Class Action”). By Order dated September 17, 2020, the two actions were deemed related; lead plaintiffs and lead plaintiffs’ counsel were subsequently appointed on December 9, 2020. On January 29, 2021, the lead plaintiffs filed their consolidated amended complaint. On July 8, 2021, all defendants moved to dismiss the consolidated amended complaint. On May 14, 2021, the court granted lead plaintiffs’ request to amend the consolidated amended complaint and denied defendants’ motions to dismiss as moot. On June 10, 2021, lead plaintiffs filed a first amended consolidated complaint. The first amended consolidated complaint names as defendants certain of Vaxart’s current and former executive officers and directors, as well as Armistice. It claims three violations of federal civil securities laws; violation of Section 10(b) of the Exchange Act and SEC Rule 10b-5, as against the Company and all individual defendants; violation of Section 20(a) of the Exchange Act, as against Armistice and all individual defendants; and violation of Section 20A of the Exchange Act against Armistice. The first amended consolidated complaint alleges that the defendants violated securities laws by misstating and/or omitting information regarding the Company’s development of a norovirus vaccine, the vaccine manufacturing capabilities of a business counterparty, and the Company’s involvement with Operation Warp Speed (“OWS”); and by engaging in a scheme to inflate Vaxart’s stock price. The first amended consolidated complaint seeks to be certified as a class action for similarly situated shareholders and seeks, among other things, an unspecified amount of damages and attorneys’ fees and costs. On July 8, 2021, all defendants moved to dismiss the first amended consolidated complaint. The motion is pending.

On October 23, 2020, a complaint was filed in the U.S. District Court for the Southern District of New York, entitled Roth v. Armistice Capital LLC, et al. The complaint names Armistice and certain Armistice-related parties as defendants, asserting a violation of Exchange Act Section 16(b) and seeking the disgorgement of short-swing profits. The complaint purports to bring the lawsuit on behalf of and for the benefit of the Company and names the Company as a “nominal defendant” for whose benefit damages are sought.

On January 8, 2021, a purported shareholder, Phillip Chan, commenced a pro se lawsuit in the U.S. District Court for the Northern District of California entitled Chan v. Vaxart, Inc. et al. (the “Opt-Out Action”). This complaint is nearly identical to an earlier version of a complaint filed in the Putative Class Actions, naming the same defendants, certain of Vaxart’s current and former executive officers and directors and Armistice, and asserting identical legal claims relating to the same factual allegations. The complaint asserts two violations of federal civil securities laws, violation of Section 10(b) of the Exchange Act and SEC Rule 10b-5 as against all defendants, and violation of Section 20(a) of the Exchange Act as against the individual defendants. The Opt-Out Action alleges that the defendants violated securities laws by misstating and omitting information regarding the Company’s development of a Covid-19 vaccine as well as its OWS involvement to deceive the investing public and inflate Vaxart’s stock price. The Opt-Out Action has been stayed pending resolution of the Putative Class Actions.

On February 4, 2021, a purported shareholder, Stephen Barker, commenced a lawsuit in the Delaware Court of Chancery entitled Barker v. Vaxart, Inc. et al. The complaint named as defendants the Company and its then-current board of directors. The complaint asserted a single claim seeking a declaration that one of the Company’s bylaws, which required a supermajority vote to remove a Company director from office, violated Delaware General Corporate Law Section 141(k). On May 14, 2021, the Court entered an Order voluntarily dismissing the action as moot.

On March 5, 2021, a purported shareholder, Kathleen Sanetel, served a demand letter on the Company’s board of directors demanding that it investigate and commence appropriate legal action against certain members of the board of directors and/or executive officers, and Armistice to remedy purportedly wrongful conduct beginning in April 2020. On or about June 2, 2021, another purported shareholder, Jerry Besa, served a substantially identical demand letter. The specific allegations and alleged wrongful conduct set forth in the demand letter are, in all material respects, substantially similar to the allegations and claims made in the consolidated amended complaint in the Putative Class Actions. After receipt of the Sanetel demand letter, the Board appointed a committee of the Board (the “Demand Committee”) and delegated to the Demand Committee the authority to investigate the matters referenced in the demand letter and determine action(s), if any, to be taken by the Company in response to the demand.

No amounts have been accrued because the Company’s management does not presently believe that any loss is probable and it is not possible to reasonably estimate the loss, or range of losses, if any, that may result from any of the ongoing litigation. The Company’s legal costs incurred in its defense against these claims are expensed as incurred.

NOTE 9. Stockholders’ Equity

(a)

Preferred Stock

The Company is authorized to issue 5,000,000 shares of preferred stock, $0.0001 par value per share. The Company’s board of directors may, without further action by the stockholders, fix the rights, preferences, privileges and restrictions of up to an aggregate of 5,000,000 shares of preferred stock in one or more series and authorize their issuance. These rights, preferences and privileges could include dividend rights, conversion rights, voting rights, terms of redemption, liquidation preferences, sinking fund terms and the number of shares constituting any series or the designation of such series, any or all of which may be greater than the rights of the Company’s common stock. The issuance of preferred stock could adversely affect the voting power of holders of common stock and the likelihood that such holders will receive dividend payments and payments upon liquidation. In addition, the issuance of preferred stock could have the effect of delaying, deterring or preventing a change of control or other corporate action. No shares of preferred stock are currently outstanding, and the Company has no present plan to issue any shares of preferred stock.

Common Stock

Except as otherwise required by law or as otherwise provided in any certificate of designation for any series of preferred stock, the holders of common stock possess all voting power for the election of the Company’s directors and all other matters requiring stockholder action. Holders of common stock are entitled to one vote per share on matters to be voted on by stockholders. Holders of common stock are entitled to receive such dividends, if any, as may be declared from time to time by the Company’s board of directors in its discretion out of funds legally available therefor. In no event will any stock dividends or stock splits or combinations of stock be declared or made on common stock unless the shares of common stock at the time outstanding are treated equally and identically. As of September 30, 2021, no dividends had been declared by the board of directors.

NOTE 10. Equity Incentive Plans

On April 23, 2019, the Company’s stockholders approved the adoption of the 2019 Equity Incentive Plan (the “2019 Plan”), under which the Company is authorized to issue incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock awards and restricted stock units, other stock awards and performance awards that may be settled in cash, stock, or other property. The 2019 Plan is designed to secure and retain the services of employees, directors and consultants, provide incentives for the Company’s employees, directors and consultants to exert maximum efforts for the success of the Company and its affiliates, and provide a means by which employees, directors and consultants may be given an opportunity to benefit from increases in the value of the Company’s common stock. Following adoption of the 2019 Plan, all previous plans were frozen, and on forfeiture, cancellation and expiration, awards under those plans are not assumed by the 2019 Plan.

The aggregate number of shares of common stock authorized for issuance under the 2019 Plan was initially 1,600,000 shares, which was increased through an amendment to the 2019 Plan adopted by the Company’s stockholders (a “Plan Amendment”) on June 8, 2020, to 8,000,000, and by a Plan Amendment on June 16, 2021, to 16,900,000. Further amendments to the 2019 Plan to increase the share reserve would require stockholder approval. Awards that are forfeited or canceled generally become available for issuance again under the 2019 Plan. Awards have a maximum term of ten years from the grant date and may vest over varying periods, as specified by the Company’s board of directors for each grant.

A summary of stock option transactions in the nine months ended September 30, 2021, is as follows:

							*Weighted*
	*Shares*			*Number of*			*Average*
	*Available*			*Options*			*Exercise*
	*For Grant*			*Outstanding*			*Price*

Balance at January 1, 2021		1,230,863			6,813,033		$	2.70
2019 Plan Amendment		8,900,000			—		$	—
Granted		(4,122,438	)		4,122,438		$	7.24
Exercised		—			(771,344	)	$	1.61
Forfeited		554,317			(574,054	)	$	2.44

Balance at September 30, 2021		6,562,742			9,553,758		$	4.74

As of September 30, 2021, there were 9,553,758 options outstanding with a weighted average exercise price of $4.74, a weighted average remaining term of 8.55 years and an aggregate intrinsic value of $32.1 million. Of these options, 3,665,542 were vested, with a weighted average exercise price of $2.67, a weighted average remaining term of 7.27 years and an aggregate intrinsic value of $20.1 million. The Company received $1.2 million for the 771,344 options exercised during the nine months ended September 30, 2021, which had an intrinsic value of $4.6 million, and received $402,000 for the 305,179 options exercised during the nine months ended September 30, 2020, which had an intrinsic value of $1.6 million.

The weighted average grant date fair value of options awarded in the nine months ended September 30, 2021 and 2020, was $6.67 and $1.98, respectively. Their fair values were estimated using the following assumptions:

	*Nine Months Ended September 30,*
	*2021*			*2020*

Risk-free interest rate		0.91% - 1.19%			0.40% - 0.88%
Expected term (in years)		5.44 - 6.08			5.22 - 10.00
Expected volatility		122% - 131%			94% - 108%
Dividend yield		—	%		—	%

The Company measures the fair value of all stock-based awards on the grant date and records the fair value of these awards, net of estimated forfeitures, to compensation expense over the service period. Total stock-based compensation recognized for options was as follows:

	*Three Months Ended September 30,*				*Nine Months Ended September 30,*
	*2021*		*2020*		*2021*		*2020*

Research and development	$	1,206	$	268	$	2,429	$	1,405
General and administrative		893		647		3,525		2,466
Total stock-based compensation	$	2,099	$	915	$	5,954	$	3,871

Effective June 16, 2021, the Company modified the terms of outstanding options awarded to its former Chairman of the Board, Wouter W. Latour, such that the vesting of 100,000 options that would otherwise have been forfeited was accelerated. Further, the post-termination exercise period for all his vested and outstanding options as of the termination date was extended from three months to the earlier of the expiry of their ten-year term and June 16, 2023. The Company recorded a charge for the incremental increase in fair value of $1.3 million, which was included in stock-based compensation expense within general and administrative expenses in the three months ended June 30, 2021.

As of September 30, 2021, the unrecognized stock-based compensation cost related to outstanding unvested stock options was $25.8 million, which the Company expects to recognize over an estimated weighted average period of 3.08 years.

NOTE 11. Related Party Transaction

In April 2020 the Company recorded a net amount of $652,000 related to the disgorgement of stockholder short-swing profits under Section 16(b) of the Securities Exchange Act of 1934, as amended. The Company recognized these related party proceeds as an increase to contributed capital on the condensed consolidated balance sheet.

Company Overview and Background

We are a clinical-stage biotechnology company primarily focused on the development of oral recombinant vaccines based on our Vector-Adjuvant-Antigen Standardized Technology (“VAAST”) proprietary oral vaccine platform. Our oral vaccines are designed to generate broad and durable immune responses that may protect against a wide range of infectious diseases and may be useful for the treatment of chronic viral infections and cancer. Our investigational vaccines are administered using a room temperature-stable tablet, rather than by injection.

We are developing prophylactic vaccine candidates that target a range of infectious diseases, including SARS-CoV-2, (the virus that causes coronavirus disease 2019 (“COVID-19”)), norovirus (a widespread cause of acute gastro-intestinal enteritis), seasonal influenza and respiratory syncytial virus (“RSV”) (a common cause of respiratory tract infections). We have completed human dosing and the active phase of our Phase 1 clinical trial for our SARS CoV-2 vaccine candidate that commenced in October 2020; the study met its primary and secondary endpoints. Three Phase 1 human studies for our norovirus vaccine candidate have been completed, including a study with a bivalent norovirus vaccine which, as we disclosed in September 2019, met its primary and secondary endpoints. Our monovalent H1 influenza vaccine generated protective immunity, similar to a licensed intramuscular vaccine, against H1 influenza infection in a Phase 2 challenge study. In addition, we are developing our first therapeutic vaccine targeting cervical cancer and dysplasia caused by human papillomavirus (“HPV”).

For the current Good Manufacturing Practice (“cGMP”) manufacturing of our candidate vaccines we are using both internal capacity and third-party manufacturers. In addition, we are developing the vaccine programs currently in our pipeline, including the SARS-CoV-2 vaccine program, the norovirus vaccine program, our seasonal flu vaccine, and the Universal Influenza vaccine collaboration with Janssen Vaccines & Prevention B.V. (“Janssen”) while also exploring partnership opportunities. Pending licensing, partnering or collaboration agreements, our RSV and HPV programs are currently on hold.

Vaxart Biosciences, Inc. was originally incorporated in California in March 2004, under the name West Coast Biologicals, Inc. and changed its name to Vaxart, Inc. (“Private Vaxart”), in July 2007, and reincorporated in the state of Delaware. On February 13, 2018, Private Vaxart completed a reverse merger (the “Merger”), with Aviragen Therapeutics, Inc. (“Aviragen”), pursuant to which Private Vaxart survived as a wholly owned subsidiary of Aviragen. Under the terms of the Merger, Aviragen changed its name to Vaxart, Inc. and Private Vaxart changed its name to Vaxart Biosciences, Inc.

Business Update Regarding COVID-19

The COVID-19 pandemic continues to present a substantial public health and economic challenge around the world and is affecting employers, employees, patients, communities and business operations, as well as the U.S. economy and financial markets. The full extent to which the continuing severity and magnitude of the COVID-19 pandemic will directly or indirectly impact our business, operations and financial condition will depend on future developments that remain highly uncertain and cannot be accurately predicted, including new information that may emerge concerning COVID-19, including its variants, the actions taken to contain it or treat its impact, the success of worldwide vaccination efforts and the economic impact on local, regional, national and international markets.

To date, we have been able to continue our operations and do not anticipate any material interruptions in the foreseeable future. However, we continue to assess the potential impact of the COVID-19 pandemic and the development of other competing COVID-19 vaccines on our business and operations, including our expenses, supply chain and clinical trials. Our partners have mostly continued to operate their facilities at or near normal levels. While we currently do not anticipate any interruptions in our operations, it is possible that the COVID-19 pandemic and response efforts may have an impact in the future on our operations and/or the operations of our third-party suppliers and partners. Any recovery from negative impacts to our business and related economic impact due to the COVID-19 pandemic may also be slowed or reversed by a number of factors, including the emergence of new variants which are more contagious.

Our Product Pipeline

The following table outlines the status of our oral vaccine development programs:

Bivalent GI.1 - GII.4 Norovirus vaccine generated IgA ASC response rates of 78 – 86% for GI.1 and 90 – 93% for GII.4. Program restarted with second dosing.

Monovalent H1 flu vaccine completed Phase 2 Proof of Concept efficacy study. Quadrivalent flu Phase 1 on hold pending partnering process.

Janssen collaboration. Initial report submitted to Janssen, discussions are ongoing.

RSV program to be partnered with new antigen partner. Program presently on hold.

HPV therapeutic pre-IND feedback received. Program presently on hold.

We are developing the following tablet vaccine candidates, which are based on our proprietary platform:

●

Coronavirus Vaccine. We are developing an oral tablet vaccine to protect against SARS-CoV-2 infection, the virus that causes COVID-19. We generated multiple vaccine candidates based on the published genome of SARS-CoV-2 and evaluated them in preclinical models for their ability to generate both mucosal and systemic immune responses. Of particular interest will be the mucosal immune responses, as coronavirus is primarily an infection of the respiratory tract. We believe the logistical advantages of an oral vaccine that is administered using a convenient room temperature-stable tablet could be of critical benefit when rolling out a major public health vaccination campaign. Given the recent emergence of coronavirus strains with mutated S proteins that are considered more contagious than the original strain, serum antibodies from injected vaccines may not adequately protect against these SARS-CoV-2 variants over time, whereas a vaccine that is able to create cross-reactive T cells against conserved epitopes may have significant advantages.

According to the U.S. Centers for Disease Control and Prevention (the “CDC”), an outbreak of COVID-19, caused by the virus SARS-CoV-2, began in Wuhan, China, in late 2019 and rapidly spread worldwide. By November 3, 2021, more than 248 million COVID-19 cases had been identified globally, including in the United States, where the CDC had reported over 46.1 million infections and 746,000 deaths. While most COVID-19 restrictions, such as stay-at-home orders, have been lifted, COVID-19 continues to spread, particularly among the unvaccinated population, and remains a public health threat, not least due to the emergence of new variants.

On September 14, 2020, we announced that the U.S. Food and Drug Administration (the “FDA”) had cleared our Investigational New Drug (“IND”) application to allow initiation of human clinical testing. On October 13, 2020, we announced that Phase 1 clinical testing had commenced and on February 3, 2021, we announced the preliminary results of the trial. The study achieved both its primary and secondary endpoints of safety and immunogenicity, respectively. We announced in February 2021 that we would evaluate vaccine candidates that contain just the Spike protein, and different variant-specific vaccines in research. After preclinical evaluations (including in non-human primate studies) showed that an improved antibody response could be achieved with a new vaccine candidate that expressed just the Spike protein, we decided to move this candidate forward for clinical evaluation. This new vaccine candidate, VXA-CoV2-1.1-S, was also able to elicit antibody responses against human coronavirus strain variants such as Beta (first identified in South Africa) and Delta (first identified in India) in animals. Further, this new vaccine candidate was tested in a vaccine breakthrough/transmission model led by Duke University and found to inhibit aerosol transmission to vaccine-naïve animals better than an injected S-protein-based vaccine candidate. These results were published in bioRxiv in October 2021.

A new IND was filed for this S-only vaccine candidate in June 2021 and was cleared by the FDA in July 2021. We initiated human trials with this candidate in a Phase 2a study in October 2021, with approximately 896 participants enrolled in a two-part study. The first part will enroll 48 participants aged 18 to 55 and 48 participants aged 56 to 75 years old, to further evaluate safety and immunogenicity and to assess optimal dosage. The second part of the study will enroll approximately 800 subjects aged 18 to 75 years old. Further, half the subjects in the trial will have already received an mRNA vaccine to test the ability of the Vaxart COVID-19 vaccine candidate to boost immune responses and enhance variant-specific cross-reactivity.

●

Norovirus Vaccine. We are developing an oral tablet vaccine for norovirus, a leading cause of acute gastroenteritis in the United States and Europe. Because norovirus infects the small intestine, we believe that our vaccine, which is designed to generate mucosal antibodies locally in the intestine in addition to systemic antibodies in the blood, may better protect against norovirus infection than an injectable vaccine. Clinical evidence that vaccines based on our platform technology can protect against infection is described in the “Seasonal Influenza Vaccine” section below. Early in 2021 we resumed this program by adding a boost dose more than 12 months after their initial dose in participants that were enrolled in the bivalent Phase 1b norovirus trial. We began a Phase 1b placebo-controlled dose ranging study in healthy elderly adults aged 55 to 80 years old in May 2021. Study enrollment is nearing completion; sample analyses to support database lock is expected in late 2021. Topline data for this trial is expected early in 2022. Lastly, a Phase 1b open-label, boost optimization study evaluating the effectiveness of boosting at different timepoints has completed enrollment and all subjects have completed visits and assessments for the study’s primary objectives. Data analysis is underway and topline results are expected before the end of 2021.

Table of Contents

Norovirus is the leading cause of acute gastroenteritis symptoms, such as vomiting and diarrhea, among people of all ages in the United States. Each year, on average, norovirus causes 19 to 21 million cases of acute gastroenteritis and contributes to 56,000 to 71,000 hospitalizations and 570 to 800 deaths, mostly among young children and older adults. Typical symptoms include dehydration, vomiting, diarrhea with abdominal cramps, and nausea. In a study by the CDC and Johns Hopkins University, published in 2016, the global economic impact of norovirus disease was estimated at $60 billion, $34 billion of which occurred in high income countries including the United States, Europe and Japan. An update by the lead authors estimated the burden in the U.S. alone to be $10.5 billion in 2018. Virtually all norovirus disease is caused by norovirus GI and GII genotypes, and we are developing a bivalent vaccine designed to protect against both. We anticipate that, if approved, the vaccine will be an annual, one-time administration ahead of the winter season when norovirus incidence is at its peak, similar to the influenza season.

Clinical Trial Update. In 2019, we completed the active phase of a Phase 1b clinical trial with our bivalent oral tablet vaccines for the GI.1 and GII.4 norovirus strains. Both the oral norovirus GI.1 and GII.4 vaccines were well tolerated with no serious adverse events reported. Most solicited and unsolicited adverse events were mild in severity, and there were no significant differences observed between the vaccine and placebo treatment groups.

Vaxart’s bivalent vaccine demonstrated robust immunogenicity, with an IgA ASC response rate of 78% for the GI.1 strain and 93% for the GII.4 strain for the bivalent cohort of the study, and 86% and 90%, respectively, for the two monovalent cohorts of the study. There was no interference observed in the bivalent arm of the study.

Having suspended our norovirus program in late 2019, we resumed clinical development of our norovirus vaccine candidate in October 2020. We have completed the boost phase (second dose after more than one year) in the Phase 1b bivalent study and recently initiated conduct of a placebo-controlled, dose ranging study in elderly adult subjects and a boost (second dose) schedule optimization study in young adults. In results announced on July 29, 2021, we showed that we were able to successfully boost immune responses with the G1.1 norovirus tablets. These responses include IgA antibody secreting cells, as well as IgG and IgA serum antibody responses. Currently, we are planning a Phase 2 safety and dose confirmation study with Vaxart’s bivalent norovirus vaccine in subjects aged 18 years and older and considering the feasibility of conducting a Phase 2 norovirus challenge study in parallel with the Phase 2 dose confirmation study. These sets of studies would form the basis (safety, immunogenicity and preliminary efficacy data) for an End of Phase 2 Meeting with the FDA to gain concurrence on the scope of the Phase 3 pivotal efficacy study in adults over 18 years of age.

Seasonal Influenza Vaccine. Influenza is a major cause of morbidity and mortality in the U.S. and worldwide and, according to the CDC, only 49% of eligible U.S. citizens were vaccinated in 2018/2019, with particularly low vaccination rates among adults between ages 18 and 49. We believe our oral tablet vaccine has the potential to improve the protective efficacy of currently available influenza vaccines and increase flu vaccination rates.

Influenza is one of the most common global infectious diseases, causing mild to life-threatening illness and even death. Approximately 350 million cases of seasonal influenza occur annually worldwide, of which three to five million cases are considered severe, causing 290,000 to 650,000 deaths per year. During the flu season of 2018/2019 there were 34,200 flu related deaths in the U.S. alone, according to the CDC. Very young children and the elderly are at the greatest risk. In the United States, between 5% and 20% of the population contracts influenza, 226,000 people are hospitalized with complications of influenza, and between 3,000 and 49,000 people die from influenza and its complications each year, with up to 90% of the influenza-related deaths occurring in adults older than 65. The total economic burden of seasonal influenza has been estimated to be $87.1 billion, including medical costs which average $10.4 billion annually, while lost earnings due to illness and loss of life amount to $16.3 billion annually.

We believe our tablet vaccine candidate may potentially address many of the limitations presented by injectable egg-based influenza vaccines for the following reasons: (i) our tablet vaccine candidates are designed to create broad and durable immune responses, which may provide more effective immunity and protect against additional strain variants; (ii) our vaccine is delivered as a room temperature-stable tablet, which we believe would provide a more convenient method of administration, enhancing patient acceptance and simplifying the distribution and administration process; (iii) we believe our tablet vaccine may be manufactured more rapidly than vaccines manufactured using egg-based methods by using recombinant methods; and (iv) using our tablet vaccine in lieu of egg-based vaccines would eliminate the risk of experiencing allergic reactions to egg protein.

In September 2018, we completed a $15.7 million contract with the U.S. Government through the Department of Health and Human Services, Office of Biomedical Advanced Research and Development Authority (“HHS BARDA”) under which a Phase 2 challenge study of our H1N1 flu vaccine candidate was conducted. Previously, we had announced that, in healthy volunteers immunized and then experimentally infected with H1 influenza, our H1 influenza oral tablet vaccine reduced clinical disease by 39% relative to placebo. Fluzone, the market-leading injectable quadrivalent influenza vaccine, reduced clinical disease by only 27%. Our tablet vaccine also showed a favorable safety profile, indistinguishable from placebo.

On October 4, 2018, we presented data from the study demonstrating that our vaccine elicited a significant expansion of mucosal homing receptor plasmablasts to approximately 60% of all activated B cells. We believe these mucosal plasmablasts are a key indicator of a protective mucosal immune response and a unique feature of our vaccines. This data also indicates that our vaccines provide protection by inducing mucosal immunity (the first line of defense against mucosal infections such as flu, norovirus and RSV), marking what could be a key advantage over injectable vaccines.

At this time, we aim to finance development and commercialization of our seasonal quadrivalent influenza oral tablet vaccine through third-party collaboration and licensing arrangements and/or non-dilutive funding. In the future, we may also consider equity offerings and/or debt financings to fund the program. Pending a licensing, partnering or collaboration agreement, the seasonal flu program is currently on hold.

Table of Contents

In addition to our conventional seasonal flu vaccine, we entered into a research collaboration agreement with Janssen in July 2019 to evaluate our proprietary oral vaccine platform for the Janssen universal influenza vaccine program. Under the agreement, we produced a non-GMP oral vaccine candidate containing certain proprietary antigens from Janssen and tested the product in a preclinical challenge model. The preclinical study has been completed and we have submitted a report to Janssen.

●

RSV Vaccine. RSV is a major respiratory pathogen with a significant burden of disease in the very young and in the elderly.

Based on the positive results of our preclinical cotton rat study, we believe our proprietary oral vaccine platform has the potential to be the optimal vaccine delivery system for RSV, offering significant advantages over injectable vaccines. We will seek to develop a tablet RSV vaccine by licensing one or more RSV protein antigens that have demonstrated protection against RSV infection in clinical studies, or by partnering with a third party with RSV antigens that can be delivered with our platform. Pending a licensing, partnering or collaboration agreement, the RSV program is currently on hold.

●

HPV Therapeutic Vaccine. Our first therapeutic oral vaccine candidate targets HPV-16 and HPV-18, the two strains responsible for 70% of cervical cancers and precancerous cervical dysplasia.

Cervical cancer is the fourth most common cancer in women worldwide and in the United States with about 13,000 new cases diagnosed annually in the United States according to the National Cervical Cancer Coalition.

We have tested our HPV-16 vaccine candidate in two different HPV-16 solid tumor models in mice. The vaccine candidate successfully elicited T cell responses and promoted migration of the activated T cells into the tumors, leading to tumor cell killing. Mice that received our HPV-16 vaccine generally showed a significant reduction in volume of their established tumors.

In October 2018, we filed a pre-IND meeting request with the FDA for our first therapeutic vaccine targeting HPV16 and HPV18 and we subsequently submitted our pre-IND briefing package. We received feedback from the FDA in January 2019 to support submission of an IND application to support initiation of clinical testing. However, the program is currently on hold while the Company is focusing its efforts on the COVID-19 vaccine.

●

Through the Merger, we acquired two royalty earning products, Relenza and Inavir. We also acquired three Phase 2 clinical stage antiviral compounds, which we have discontinued, but for one of these, Vapendavir, we have entered into an exclusive worldwide license agreement with Altesa Biosciences, Inc. (“Altesa”) on July 6, 2021, permitting Altesa to develop and commercialize this capsid-binding broad spectrum antiviral.

●

Relenza and Inavir are antivirals for the treatment of influenza, marketed by GlaxoSmithKline, plc (“GSK”) and Daiichi Sankyo Company, Limited (“Daiichi Sankyo”), respectively. We have earned royalties on the net sales of Relenza and Inavir in Japan. The last patent for Relenza expired in July 2019 and the last patent for Inavir expires in December 2029. Sales of these antivirals vary significantly by quarter, because influenza virus activity displays strong seasonal cycles, and by year depending on the intensity and duration of the flu season and competition with other antivirals such as Tamiflu. Importantly, on February 23, 2018, Xofluza, a new drug that treats influenza developed by Shionogi, was approved in Japan. The drug has gained significant market share, substantially reducing sales of Inavir.

Financial Operations Overview

Revenue

Revenue from Customer Service Contracts

We earned revenue from a fixed price service contract, as amended, for a total of $617,000, which we completed in the first three months of 2021.

Royalty Revenue

We earn royalty revenue on sales of Inavir and, until the patent expired, Relenza,both treatments for influenza, from our licensees, Daiichi Sankyo and GSK, respectively, under royalty agreements with expiry dates in December 2029 and July 2019, respectively, based on fixed percentages of net sales of these drugs.

Non-Cash Royalty Revenue Related to the Sale of Future Royalties

In April 2016, Aviragen sold certain royalty rights related to Inavir in the Japanese market for $20.0 million to HealthCare Royalty Partners III, L.P. (“HCRP”). At the time of the Merger, the fair value of the estimated future benefit to HCRP was $15.9 million, which we recorded as a liability that we are amortizing using the effective interest method over the remaining estimated life of the arrangement. Even though we did not retain the related royalties under the transaction, as the amounts are remitted to HCRP, we will continue to record revenue related to these royalties until the amount of the associated liability and related interest is fully amortized.

Research and Development Expenses

Research and development expenses represent costs incurred on conducting research, such as developing our tablet vaccine platform, and supporting preclinical and clinical development activities of our tablet vaccine candidates. We recognize all research and development costs as they are incurred. Research and development expenses consist primarily of the following:

●

employee-related expenses, which include salaries, benefits and stock-based compensation;

●

expenses incurred under agreements with contract research organizations (“CROs”), that conduct clinical trials on our behalf;

●

expenses incurred under agreements with contract manufacturing organizations (“CMOs”), that manufacture product used in the clinical trials;

●

expenses incurred in procuring materials and for analytical and release testing services required to produce vaccine candidates used in clinical trials;

●

process development expenses incurred internally and externally to improve the efficiency and yield of the bulk vaccine and tablet manufacturing activities;

●

laboratory supplies and vendor expenses related to preclinical research activities;

●

consultant expenses for services supporting our clinical, regulatory and manufacturing activities; and

●

facilities, depreciation and allocated overhead expenses.

We do not allocate our internal expenses to specific programs. Our employees and other internal resources are not directly tied to any one research program and are typically deployed across multiple projects. Internal research and development expenses are presented as one total.

We incur significant external costs to manufacture our tablet vaccine candidates, and for CROs that conduct clinical trials on our behalf. We capture these expenses for each vaccine program. We do not allocate external costs incurred on preclinical research or process development to specific programs.

The following table shows our period-over-period research and development expenses, identifying external costs that were incurred in each of our vaccine programs and, separately, on preclinical research and process development (in thousands):

	Three Months Ended September 30,				Nine Months Ended September 30,
	2021		2020		2021		2020
External program costs:
COVID-19 program	$	1,860	$	1,436	$	8,020	$	3,301
Norovirus program		1,202		215		2,746		475
All other programs		—		—		—		7
Preclinical research		870		323		1,811		695
Process development		386		90		1,680		136
Total external costs		4,318		2,064		14,257		4,614
Internal costs		8,091		2,552		18,962		6,658
Total research and development	$	12,409	$	4,616	$	33,219	$	11,272

We expect that research and development expenses will continue to increase as we advance our tablet vaccine candidates further into and through additional clinical trials, pursue regulatory approval of our tablet vaccine candidates and prepare for a possible commercial launch, all of which will also require a significant investment in manufacturing and inventory related costs. To the extent that we enter into licensing, partnering or collaboration agreements, a significant portion of such costs may be borne by third parties.

The process of conducting clinical trials necessary to obtain regulatory approval is costly and time consuming. We may never succeed in achieving marketing approval for an oral tablet COVID-19 vaccine candidate, or any of our tablet vaccine candidates. The probability of successful commercialization of our tablet vaccine candidates may be affected by numerous factors, including clinical data obtained in future trials, competition, manufacturing capability and commercial viability. As a result, we are unable to determine the duration and completion costs of our research and development projects or when and to what extent we will generate revenue from the commercialization and sale of any of our tablet vaccine candidates.

General and Administrative Expense

General and administrative expenses consist of personnel costs, allocated expenses and expenses for outside professional services, including legal, audit, accounting, public relations, market research and other consulting services. Personnel costs consist of salaries, benefits and stock-based compensation. Allocated expenses consist of rent, depreciation and other facilities related expenses.

Revenue from Customer Service Contracts

We earned revenue from customer service contracts of $13,000 in the nine months ended September 30, 2021, all in the first quarter, and $2,000 and $193,000 in the three and nine months ended September 30, 2020, respectively. This revenue was recognized from a fixed price contract executed in July 2019, as amended, for a total of $617,000, which we have now completed.

Table of Contents

Royalty Revenue

For the three months ended September 30, 2021 and 2020 we earned no royalty revenue. For the nine months ended September 30, 2021, we earned no royalty revenue, compared to $3.0 million earned in the nine months ended September 30, 2020, $2.8 million of which related to Inavir and was earned in the three months ended March 31, 2020, with the remainder related to Relenza, for which we are no longer entitled to receive royalties. We do not recognize any royalty revenue from sales of Inavir until the first $3 million net of 5% withholding tax in years ending on March 31 has been recognized as non-cash royalty revenue related to sale of future royalties. We recognized no royalty revenue in the year ended March 31, 2021, because net royalties were only $1.3 million, compared to $6.4 million in the year ended March 31, 2020. We believe this 80% decrease is primarily because social distancing, mask wearing and increased influenza vaccination rates due to the COVID-19 pandemic have caused the number of influenza infections to decline. Due to the unpredictability of the impact of COVID-19 on future flu seasons we are unable to forecast the amount of royalty revenue, if any, that we will earn in the future.

Non-cash Royalty Revenue Related to Sale of Future Royalties

For the three months ended September 30, 2021, non-cash royalty revenue related to sale of future royalties was $200,000, compared to $263,000 in the three months ended September 30, 2020, the decrease being due to a reduction in sales of Inavir in Japan. For the nine months ended September 30, 2021, non-cash royalty revenue related to sale of future royalties was $805,000, compared to $535,000 in the nine months ended September 30, 2020. The increase is due to a ceiling of $3.3 million that may be earned in years ending on March 31, and for the year ended March 31, 2020, we recognized all but $34,000 of this in the nine months ended December 31, 2019, whereas in the year ended March 31, 2021, total royalty revenue from Inavir sales was only $1.3 million, including $493,000 in the three months ended March 31, 2021, all of which was recognized as non-cash royalty revenue.

Total Operating Expenses

The following table presents our operating expenses for the three and nine months ended September 30, 2021 and 2020 (in thousands, except percentages):

	Three Months Ended September 30,								Nine Months Ended September 30,
	2021		2020			% Change			2021		2020			% Change

Total operating expenses	$	17,451	$	7,854			122	%	$	49,355	$	20,499			141	%

Research and Development

For the three months ended September 30,2021, research and development expenses increased by $7.8 million, or 169%, compared to the three months ended September 30,2020, and for the nine months ended September 30, 2021, they increased by $21.9 million, or 195%, compared to the nine months ended September 30, 2020. The increase in both periods is primarily due to preclinical, manufacturing and clinical expenses related to our COVID-19 and norovirus vaccine candidates and increased personnel costs, including stock-based compensation, and facilities allocation related to headcount increases.

We expect that research and development expenses will be significantly higher in 2021 and beyond than in 2020 as we continue to increase our headcount and incur significant expenditures on manufacturing and clinical trials for our COVID-19 and norovirus vaccine candidates.

General and Administrative

For the three months ended September 30, 2021, general and administrative expenses increased by $852,000, or 20%, compared to the corresponding period in 2020. The principal reasons are higher professional fees other than attorney costs, increased personnel costs and facilities allocation in line with our corporate growth and additional directors and officers liability insurance costs, partially offset by a reduction in net legal fees, mainly due to reimbursements.

For the nine months ended September 30, 2021, general and administrative expenses increased by $6.1 million, or 60%, compared to the corresponding period in 2020. The principal reasons are higher legal fees and other professional costs, additional directors and officers liability insurance costs, the non-cash expense for modifying the terms of outstanding options awarded to our former Chairman of the Board and increased personnel costs, facilities allocation and recruitment costs, in line with our corporate growth, partially offset by the absence of severance expenses for our former Chief Executive Officer.

Restructuring Costs

The net reversal of restructuring costs in the three months ended September 30, 2020, relates to the settlement for less than the maximum amount potentially payable for a manufacturing work order that we suspended in conjunction with our restructuring at the end of 2019. In the nine months ended September 30, 2020, this was partially offset by legal fees and accretion costs. We have not incurred any charges related to restructuring since September 30, 2020, and do not expect any further adjustments.

Net non-operating income and (expenses)	$	(311	)	$	(470	)		(34	)%	$	(1,080	)	$	(1,345	)		(20	)%

For the three months ended September 30, 2021, we recorded net non-operating expenses of $311,000, a 34% decrease from the $470,000 recorded in the three months ended September 30, 2020. For the nine months ended September 30, 2021, we recorded net non-operating expenses of $1.1 million, a 20% decrease from the $1.3 million recorded in the nine months ended September 30, 2020.

Interest income decreased in the nine months ended September 30, 2021, compared to the nine months ended September 30, 2020, despite higher cash and investment balances, because of lower interest rates, although rates did increase in the three months ended September 30, 2021. Non-cash interest expense related to sale of future royalties, which relates to accounting for amounts that will become payable to HCRP for royalty revenue earned from Inavir as debt, decreased in both the three and nine months ended September 30, 2021, compared to the respective corresponding periods in the prior year, as the outstanding balance due to HCRP has been paid down and, effective April 1, 2021, the imputed interest rate decreased.

Provision for Income Taxes

The following table presents our provision for income taxes for the three and nine months ended September 30, 2021 and 2020, respectively (in thousands, except percentages):

	Three Months Ended September 30,								Nine Months Ended September 30,
	2021			2020		% Change			2021		2020		% Change
Foreign withholding tax on royalty revenue	$	10		$	13		(23	)%	$	40	$	165		(76	)%
Foreign taxes payable on intercompany interest		15			13		15	%		48		39		23	%
State income taxes		(4	)		—		N/A			1		1		—	%
Provision for income taxes	$	21		$	26		(19	)%	$	89	$	205		(57	)%

The provision for income taxes comprises $21,000 and $26,000 in the three months ended September 30, 2021 and 2020, respectively. The majority of the charge relates to interest on an intercompany loan from a foreign subsidiary on which the balance due has increased.

The provision for income taxes comprises $89,000 and $205,000 in the nine months ended September 30, 2021 and 2020, respectively. A significant portion of the charge represents withholding tax on royalty revenue earned on sales of Inavir in Japan, which is potentially recoverable as a foreign tax credit but expensed because we record a 100% valuation allowance against our deferred tax assets. The decrease arose because Inavir royalties, net of withholding tax, including the portion that we pass through to HCRP, fell from $3.1 million in the nine months ended September 30, 2020, to $765,000 in the nine months ended September 30, 2021. In addition, we incur charges relating to interest on our intercompany loan from a foreign subsidiary and U.S. state income taxes.

Liquidity and Capital Resources

Our primary source of financing is from the sale and issuance of common stock and common stock warrants in public offerings, along with proceeds from the exercise of warrants. In the past, we have also obtained funds from the issuance of secured debt and preferred stock and from collaboration agreements. In October 2020 we entered into an Open Market Sale Agreement (the “October 2020 ATM”), under which we could sell shares of our common stock having an aggregate offering price of up to $250 million. Having sold shares under the October 2020 ATM for aggregate gross proceeds of $133.4 million, we terminated the October 2020 ATM in September 2021 and entered into a Controlled Equity Offering Sales Agreement (the “September 2021 ATM”), under which we may offer and sell, from time to time through sales agents, shares of our common stock having an aggregate offering price of up to $100 million. We will incur direct expenses and pay sales commissions of up to 3.0% of gross proceeds from the sale of shares under the September 2021 ATM.

As of September 30, 2021, we had approximately $204.0 million of cash, cash equivalents and liquid investments. There is approximately $96 million in net proceeds available to us under the September 2021 ATM.

We believe our existing funds are sufficient to fund us into 2023. To continue operations thereafter, we expect that we will need to raise further capital, through the sale of additional securities or otherwise. Our operating needs include the planned costs to operate our business, including amounts required to fund working capital and capital expenditures. Our future capital requirements and the adequacy of our available funds will depend on many factors, most notably our ability to successfully commercialize our products and services.

We may fund a significant portion of our ongoing operations through partnering and collaboration agreements which, while reducing our risks and extending our cash runway, will also reduce our share of eventual revenues, if any, from our vaccine product candidates. We may be able to fund certain activities with assistance from government programs including HHS BARDA. The sale of additional equity would result in additional dilution to our stockholders. We may also fund our operations through debt financing. Incurring debt would result in debt service obligations, and the instruments governing such debt could provide for operating and financing covenants that would restrict our operations. If we are unable to raise additional capital in sufficient amounts or on acceptable terms, we may be required to delay, limit, reduce, or terminate our product development or future commercialization efforts or grant rights to develop and market vaccine candidates that we would otherwise prefer to develop and market ourselves. Any of these actions could harm our business, results of operations and prospects.

Our future funding requirements will depend on many factors, including the following:

●

the timing and costs of our planned preclinical studies for our product candidates;

●

the timing and costs of our planned clinical trials of our product candidates;

●

our manufacturing capabilities, including the availability of contract manufacturing organizations to supply our product candidates at reasonable cost;

●

the amount and timing of royalties received on sales of Inavir;

●

the number and characteristics of product candidates that we pursue;

●

the outcome, timing and costs of seeking regulatory approvals;

●

revenue received from commercial sales of our future products, which will be subject to receipt of regulatory approval;

●

the terms and timing of any future collaborations, licensing, consulting or other arrangements that we may enter into;

●

the amount and timing of any payments that may be required in connection with the licensing, filing, prosecution, maintenance, defense and enforcement of any patents or patent applications or other intellectual property rights; and

●

the extent to which we in-license or acquire other products and technologies.

Net Cash Used in Operating Activities

Vaxart experienced negative cash flow from operating activities for the nine months ended September 30, 2021 and 2020, in the amounts of $44.0 million and $13.0 million, respectively. The cash used in operating activities in the nine months ended September 30, 2021, was due to cash used to fund a net loss of $49.7 million and an increase in working capital of $3.6 million, partially offset by adjustments for net non-cash income related to depreciation and amortization, accretion of premium on investments, stock-based compensation, non-cash interest expense related to sale of future royalties and non-cash revenue related to sale of future royalties totaling $9.3 million. The cash used in operating activities in the nine months ended September 30, 2020, was due to cash used to fund a net loss of $18.4 million, partially offset by adjustments for net non-cash income related to depreciation and amortization, stock-based compensation, non-cash interest expense related to sale of future royalties and non-cash revenue related to sale of future royalties totaling $4.1 million and a decrease in working capital of $1.3 million.

Net Cash Used in Investing Activities

In the nine months ended September 30, 2021, we used $36.8 million to purchase marketable securities, net of maturities. We used $4.1 million and $321,000 to purchase property and equipment in the nine months ended September 30, 2021 and 2020, respectively. We received cash of $3,000 for the sale of equipment in the nine months ended September 30, 2020.

Net Cash Provided by Financing Activities

In the nine months ended September 30, 2021, we received $122.2 million from the sale of common stock under the October 2020 ATM and $3.1 million from the exercise of common stock warrants and stock options. In the nine months ended September 30, 2020, we received $9.2 million from the sale of common stock and warrants in a registered direct offering in March, $97.0 million from the sale of common stock under an at-the-market facility in July, $26.4 million from the exercise of common stock warrants and stock options, and net proceeds of $652,000 from the disgorgement of related party short-swing profits.

Contractual Obligations and Commercial Commitments

We have the following contractual obligations and commercial commitments as of September 30, 2021 (in thousands):

Contractual Obligation	Total		< 1 Year		1 - 3 Years		3 - 5 Years		> 5 Years

Long Term Debt, HCRP	$	20,675	$	3,118	$	6,102	$	5,261	$	6,194

Total	$	71,961	$	24,661	$	13,642	$	14,248	$	19,410

Long Term Debt, HCRP. Under an agreement executed in 2016, we are obligated to pay HCRP the first $3 million plus 15% of the next $1 million of royalty revenues that we earn for sales of Inavir in each year ending on March 31. See Note 6 to the Condensed Consolidated Financial Statements in Part I, Item 1 for further details.

Operating leases. Operating lease amounts include future minimum lease payments under all our non-cancellable operating leases with an initial term in excess of one year, including a total of $14.9 million for one lease that has been executed but has not yet commenced. See Note 7 to the Condensed Consolidated Financial Statements in Part I, Item 1 for further details of leases that have commenced.

Purchase obligations. These amounts include an estimate of all open purchase orders and contractual obligations in the ordinary course of business, including commitments with contract manufacturers and suppliers for which we have not received the goods or services. We consider all open purchase orders, which are generally enforceable and legally binding, to be commitments, although the terms may afford us the option to cancel based on our business needs prior to the delivery of goods or performance of services.

Off-Balance Sheet Arrangements

We had no off-balance sheet arrangements in the periods presented.

Table of Contents

Critical Accounting Policies and Estimates

Our management’s discussion and analysis of financial condition and results of operations is based on our condensed consolidated financial statements, which have been prepared in accordance with generally accepted accounting principles in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities and expenses. On an ongoing basis, we evaluate these estimates and judgments. We base our estimates on historical experience and on various assumptions that we believe to be reasonable under the circumstances. These estimates and assumptions form the basis for making judgments about the carrying values of assets and liabilities and the recording of expenses that are not readily apparent from other sources. Actual results may differ materially from these estimates. We believe that the accounting policies discussed below are critical to understanding our historical and future performance, as these policies relate to the more significant areas involving management’s judgments and estimates.

Accrued Research and Development Expenses

We record accrued expenses for estimated costs of research and development activities conducted by third-party service providers, which include the conduct of preclinical studies, clinical trials and manufacturing activities. We record the estimated costs of research and development activities based upon the estimated amount of services provided and include the costs incurred but not yet invoiced within accrued liabilities in the condensed consolidated balance sheets and within research and development expense in the condensed consolidated statements of operations and comprehensive loss. These costs can be a significant component of our research and development expenses.

We estimate the amount of work completed through discussions with internal personnel and external service providers as to the progress or stage of completion of the services and the agreed-upon fee to be paid for such services. We make significant judgments and estimates in determining the accrued balance in each reporting period. As actual costs become known, we adjust our accrued estimates.

Intangible Assets

Intangible assets acquired in the Merger were recorded at their estimated fair values of $20.3 million for developed technology related to Inavir which is being amortized on a straight-line basis over the estimated period of future royalties of 11.75 years and $1.8 million for the developed technology related to Relenza which was fully amortized over the remaining royalty period of 1.3 years. These valuations were prepared by an independent third party based on estimated discounted cash flows based on probability-weighted future development expenditures and revenue streams, which are highly subjective.

Recent Accounting Pronouncements

See the “Recent Accounting Pronouncements” in Note 2 to the Condensed Consolidated Financial Statements in Part I, Item 1 for information related to the issuance of new accounting standards in the first nine months of 2021, none of which had a material impact on our condensed consolidated financial statements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Sensitivity

Our exposure to market risk for changes in interest rates relates primarily to our investments in marketable debt securities. The primary objective of our investment activities is to preserve principal, maintain liquidity that is sufficient to meet cash needs and maximize total return without significantly increasing risk. To achieve this goal, we maintain our excess cash and cash equivalents in money market funds and debt securities. We do not enter into investments for trading or speculative purposes and we hold no equity securities. We presently have no borrowings or lines of credit.

Specifically, as of September 30, 2021, we had cash, cash equivalents and investments of approximately $204.0 million, which consist of bank deposits, money market funds, direct obligations of the U.S. government or its agencies, commercial paper and corporate bonds. All of our investments must satisfy high credit rating requirements at the time of purchase. Such interest-earning instruments carry a degree of interest rate risk, however, because our investments are rated highly and mostly short-term, we believe that our exposure to risk of loss due to interest rate changes is not significant.

Table of Contents

Exchange Rate Sensitivity

Our royalty revenue, which is calculated in U.S. dollars, is based on sales in Japanese yen, so a 1% increase in the strength of the U.S. dollar against the yen would lead to a 1% reduction in royalty revenue. Presently, we are not retaining any cash related to our income from royalties and all of our other revenue, and substantially all of our expenses, assets and liabilities, are denominated in U.S. dollars. As a result, we have not experienced significant foreign exchange gains or losses recently and consider our exposure to exchange rate fluctuations to be insignificant.

Our management, with the participation of our President and Chief Executive Officer (who serves as our principal executive officer and principal financial officer), has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on such evaluation, our management has concluded that our disclosure controls and procedures were effective at a reasonable assurance level as of September 30, 2021.

Changes in Internal Control over Financial Reporting

There was no material change in our internal control over financial reporting that occurred during the quarter ended September 30, 2021, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls

Our management, including our President and Chief Executive Officer, does not expect that our disclosure controls and procedures or our internal controls will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within Vaxart have been detected.

PART II OTHER INFORMATION

Item 1. Legal Proceedings

The information included in “Note 8. Commitments and Contingencies—(c) Litigation” to the Condensed Consolidated Financial Statements in Part I, Item 1 is incorporated by reference into this Item.

We may also from time to time be involved in legal proceedings arising in connection with our business. Based on information currently available, we believe that the amount, or range, of reasonably possible losses in connection with any pending actions against us in excess of established reserves, in the aggregate, is not material to our consolidated financial condition or cash flows. However, any current or future dispute resolution or legal proceeding, regardless of the merits of any such proceeding, could result in substantial costs and a diversion of management’s attention and resources that are needed to run our business successfully, and could have a material adverse impact on our business, financial condition and results of operations.

Item 1A. Risk Factors

You should consider the risks and uncertainties described under Item 1A of Part I of our Annual Report on Form 10-K for the fiscal year ended December 31, 2020, which we filed with the Securities and Exchange Commission on February 25, 2021, together with all other information contained or incorporated by reference in this Quarterly Report on Form 10-Q, including the risk factor described below, when evaluating our business and our prospects. Other than as set forth below, there are no material changes to the risk factors set forth in Part I, Item 1A, in our Annual Report on Form 10-K for the year ended December 31, 2020.

We are currently engaged in an ongoing opposition proceeding of a Vaxart European patent in the European Patent Office. If we are not successful in these proceedings, we may not be able to prevent others in Europe from copying some of our product candidates for as long as we otherwise would if the European patent is upheld.

We are currently engaged in an ongoing opposition proceeding of one of our European patents in the European Patent Office. European Patent No. 3307239, which has claims directed to vaccine compositions for norovirus and Respiratory Syncytial Virus (“RSV”), was opposed in the European Patent Office. The ultimate outcome of the opposition remains uncertain. If Vaxart is not ultimately successful in the proceedings, it may not be able to prevent others from copying its norovirus and RSV products in some or all European countries for as long as it otherwise might be able to if the patent’s validity is upheld in the opposition. If the opposed European patent is partially or fully revoked by the European Patent Office, competitors may be able to sell competing vaccines for norovirus or RSV earlier without Vaxart being able to assert patents against them. Vaxart has another patent in Europe that covers its norovirus and RSV products, but lack of success in the opposition would prevent us from extending that patent protection out to 2036.
