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 “Sales Agreement”) 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 $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 will pay sales commissions of 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 Sales Agreement of $4.9 million in 2020.

In the three months ended March 31, 2021, the Company sold an additional 6,654,367 shares for gross proceeds of $68.9 million which, after deducting sales commissions and expenses, resulted in net proceeds to date under the Sales Agreement of $65.7 million. A total of 7,347,018 shares have been issued under the Sales Agreement since its inception for gross proceeds of $74.4 million which, after deducting sales commissions and expenses, has resulted in net proceeds of $70.6 million.

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”). Except as 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.

VAXART, INC. AND SUBSIDIARIES

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, available-for-sale investments and accounts receivable. 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. The Company generally requires no collateral from its customers.

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 has 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 March 31, 2021 (in thousands):

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

NOTE 5. Revenue

Service Contracts with Customers

Contract Balances. Accounts receivable related to service contracts with customers as of March 31, 2021 and December 31, 2020, was $232,000 and nil, respectively. Contract assets, representing unbilled receivables where revenue has been recognized in advance of customer billings, as of March 31, 2021 and December 31, 2020, was nil and $219,000, respectively, which is included in prepaid expenses and other current assets.

Remaining Performance Obligations. Remaining Performance Obligations (“RPO”) comprise deferred revenue plus unbilled contract revenue. As of March 31, 2021 and December 31, 2020, there was no deferred revenue and the aggregate amount of RPO was nil and $13,000, respectively, all of which was unbilled contract revenue which is not recorded on the balance sheet. Unbilled contract revenue represents non-cancelable contracts under which the Company has an obligation to perform, for which revenue has not yet been recognized in the financial statements and the fixed amounts billable have not yet been invoiced.

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 three months ended March 31, 2021 or 2020.

Table of Contents

VAXART, INC. AND SUBSIDIARIES

Notes to the Condensed Consolidated Financial Statements (Unaudited)

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 three months ended March 31, 2021 and 2020, was nil and $2,769,000, respectively, representing 4% of net sales in Japan. In addition, the Company recognized non-cash royalty revenue related to the sale of future royalties (see Note 6) of $493,000 and $34,000 in the three months ended March 31, 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 $25,000 and $140,000 was included in income tax expense in the three months ended March 31, 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 three months ended March 31, 2021 (in thousands):

Total liability related to sale of future royalties, start of period	$	14,929
Non-cash royalty revenue paid to HCRP		(334	)
Non-cash interest expense recognized		466
Total liability related to sale of future royalties, end of period		15,061

The Company obtained the right of use of real estate located in South San Francisco, California, in November 2020 under a lease that terminates on September 30, 2025, 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. 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 two facilities located in South San Francisco, California, under leases that terminate on July 31, 2021, with no extension options, and the right of use of equipment under a lease that terminates in September 2021. Further, the Company has 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 early in 2022, and a short-term embedded lease for the rental of facilities in Lodi, California.

As of March 31, 2021, the weighted average discount rate for operating leases with initial terms of more than one year was 9.92% and the weighted average remaining term of these leases was 3.96 years. Discount rates were determined using the Company’s marginal rate of borrowing at the time each lease was executed or 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 March 31, 2021 (in thousands):

Year Ending December 31,
2021 (nine months remaining)	$	1,887
2022		1,801
2023		1,585
2024		1,641
2025		1,112
Undiscounted total		8,026
Less: imputed interest		(1,392	)
Present value of future minimum payments		6,634
Current portion of operating lease liability		(2,006	)
Operating lease liability, net of current portion	$	4,628

The Company presently has no finance leases and no future obligations under operating leases for equipment with initial terms of one year or less.

Certain operating lease agreements for facilities include non-lease costs, such as common area maintenance, which are recorded as variable lease costs. Operating lease expenses for the three months ended March 31, 2021 and 2020, are summarized as follows (in thousands):

	*Three Months Ended March 31,*
	*2021*			*2020*
Lease cost
Operating lease cost	$	662		$	189
Short-term lease cost		60			3
Variable lease cost		293			11
Sublease income		(36	)		(54	)
Total lease cost	$	979		$	149

Net cash outflows associated with operating leases totaled $934,000 and $237,000 in the three months ended March 31, 2021 and 2020, respectively.

NOTE 8. Commitments and Contingencies

(a)

Purchase Commitments

As of March 31, 2021, the Company had approximately $26.8 million of non-cancelable purchase commitments, principally for contract manufacturing and clinical services which are expected to be paid within the next eighteen months. In addition, the Company has operating lease commitments as detailed in Note 7.

(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. The second amended complaint names certain of Vaxart’s officers and 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, unjust enrichment, and aiding and abetting breach of fiduciary duty against Armistice Capital, LLC (“Armistice”). The claims challenge certain stock options granted to certain of the Company’s officers and directors between March 24, 2020 and June 15, 2020 and certain amendments to two warrants held by Armistice, as disclosed on June 8, 2020. The second 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 December 30, 2020, all defendants in the action filed a demurrer with the court addressing the second amended complaint, seeking to have the entire case dismissed. On March 15, 2021, the court sustained the demurrer, dismissing the complaint in its entirety, without prejudice to file a newly-amended complaint.

On September 8, 2020, a purported shareholder derivative complaint was filed in the Chancery Court in 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. The complaints name as defendants certain of Vaxart’s current and former directors, 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 complaints also assert claims against Armistice. The complaints challenge certain stock options granted to certain of the Company’s officers and directors between March 24, 2020 and June 15, 2020 and certain amendments made to two warrants held by Armistice, as disclosed on June 8, 2020. Both complaints purport to bring suit derivatively on behalf of and for the benefit of the Company, and the Jaquith complaint also purports to assert a direct claim for breach of fiduciary duty on behalf of a class of Vaxart stockholders. Both complaints name the Company as a “nominal defendant” against which no claims are asserted and no damages are sought. On October 9, 2020, all defendants moved to dismiss the Galjour complaint and to stay the action pending disposition of the Ennis action in California. On November 12, 2020, the Galjour and Jaquith actions were consolidated under the caption In re Vaxart, Inc. Stockholder Litigation and the complaint filed in the Jaquith v. Latour action was deemed the operative pleading. On January 4, 2021, all defendants filed motions to dismiss, seeking to have the case dismissed. Those motions remain pending.

On September 17, 2020, a purported derivative complaint was filed in the U.S. District Court for the Northern District of California, entitled Stachowski v. Boyd, et al. The complaint names as defendants certain of Vaxart’s current 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 alleges a violation of §14(a) of the Securities Exchange Act of 1934 for allegedly false statements or omissions in the Company’s April 24, 2020, proxy statement regarding the Company’s options practices. The complaint also asserts a claim for breach of fiduciary duty against Armistice. The claims are based on allegations that certain stock options granted to certain of the Company’s officers and directors between March 24, 2020 and June 15, 2020, were allegedly improper and that certain warrants held by Armistice were amended on June 8, 2020, allegedly for no consideration. The 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 claims are asserted and no damages are sought. On November 13, 2020, plaintiffs voluntarily withdrew their claims and the case was dismissed.

VAXART, INC. AND SUBSIDIARIES

Notes to the Condensed Consolidated Financial Statements (Unaudited)

Two substantially similar securities class actions were filed in the U.S. District Court for the Northern District of California, the first, titled Himmelberg v. Vaxart, Inc. et al. was filed on August 24, 2020 (the “Himmelberg Action”), and the second action, titled Hovhannisyan v. Vaxart, Inc. et al. was filed on September 1, 2020 (the “Hovhannisyan Action,” and together, the “Putative Class Actions”). On September 17, 2020, the court issued an order that the Putative Class Actions were related and would proceed as one consolidated action. On December 9, 2020, the court appointed the lead plaintiffs and lead plaintiffs’ counsel and on January 29, 2021, the lead plaintiffs filed their consolidated amended complaint. The consolidated amended complaint names as defendants certain of Vaxart’s current and former executive officers and directors, and Armistice. It claims two violations of federal civil securities laws, violation of SEC Rule 10b-5, as against all defendants; violation of Section 20(a) of the Exchange Act, as against all defendants except for Vaxart; and violation of Section 20A of the Exchange Act against Armistice. The consolidated amended complaint alleges that the defendants violated securities laws by misstating and omitting information regarding the Company’s development of a norovirus vaccine, the vaccine manufacturing capabilities of a business counterparty, as well as the Company’s Operation Warp Speed (“OWS”) involvement to deceive the investing public and inflate Vaxart’s stock price. The consolidated amended complaint seeks to be certified as a class action for similarly situated shareholders and seek, among other things, an uncertain amount of damages and attorneys’ fees and costs. Defendants have filed motions to dismiss the consolidated amended complaint, which is pending.

On October 23, 2020, a purported shareholder derivative 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 an Armistice-affiliated Company director as defendants, asserting a violation of Exchange Act Section 16(b) and seeking the disgorgement of short-swing profits obtained in violation thereof. The 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 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 titled Chan v. Vaxart, Inc. et al. (the “Opt-Out Action”). This complaint is nearly identical to an earlier version of the 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 titled Barker v. Vaxart, Inc. et al. The complaint names as defendants the Company and its current board of directors. The complaint asserts a single claim for declaratory relief seeking a declaration that one of the Company’s bylaws, which requires a supermajority vote to remove a Company director from office, is in violation of Delaware General Corporate Law Section 141(k). It does not seek damages.

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. 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 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.

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.

VAXART, INC. AND SUBSIDIARIES

Notes to the Condensed Consolidated Financial Statements (Unaudited)

(b)

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 March 31, 2021, no dividends had been declared by the board of directors.

In the event of the Company’s voluntary or involuntary liquidation, dissolution, distribution of assets or winding-up, the holders of the common stock will be entitled to receive an equal amount per share of all of the Company’s assets of whatever kind available for distribution to stockholders, after the rights of the holders of the preferred stock have been satisfied. There are no sinking fund provisions applicable to the common stock.

The Company had shares of common stock reserved for issuance as follows:

	*March 31, 2021*		*December 31, 2020*

Options issued and outstanding		7,764,164		6,813,033
Available for future grants of equity awards		67,863		1,230,863
Common stock warrants		414,252		1,244,974
Total		8,246,279		9,288,870

(c)

Warrants

The following warrants were outstanding as of March 31, 2021, all of which contain standard anti-dilution protections in the event of subsequent rights offerings, stock splits, stock dividends or other extraordinary dividends, or other similar changes in the Company’s common stock or capital structure, and none of which have any participating rights for any losses:

Securities into which warrants are convertible	Warrants outstanding		Exercise Price		Expiration Date

Common Stock		5,000	$	0.30	September 2024
Common Stock		225,966	$	1.10	April 2024
Common Stock		26,515	$	1.375	April 2024
Common Stock		29,150	$	2.50	March 2025
Common Stock		100,532	$	3.125	February 2025
Common Stock		16,175	$	3.125	March 2024
Common Stock		10,914	$	22.99	December 2026
Total		414,252

In the event of a Fundamental Transaction (a transfer of ownership of the Company as defined in the warrant) within the Company’s control, the holders of the unexercised common stock warrants exercisable for $0.30, $1.10 and $2.50 and those exercisable for $3.125 expiring in February 2025 shall be entitled to receive cash consideration equal to a Black-Scholes valuation, as defined in the warrant. If such Fundamental Transaction is not within the Company’s control, the warrantholders would only be entitled to receive the same form of consideration (and in the same proportion) as the holders of the Company’s common stock, hence these warrants are classified as a component of permanent equity.

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 on June 8, 2020, to 8,000,000 (the “Plan Amendment”). Further amendments to the 2019 Plan to increase the share reserve would require stockholder approval. Awards that expire or are 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 three months ended March 31, 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
Granted		(1,163,000	)		1,163,000		$	6.27
Exercised		—			(207,730	)	$	1.11
Canceled		—			(4,139	)	$	5.17

Balance at March 31, 2021		67,863			7,764,164		$	3.28

As of March 31, 2021, there were 7,764,164 options outstanding with a weighted average exercise price of $3.28, a weighted average remaining term of 8.91 years and an aggregate intrinsic value of $23.5 million. Of these options, 3,007,780 were vested, with a weighted average exercise price of $2.65, a weighted average remaining term of 8.48 years and an aggregate intrinsic value of $11.3 million. The Company received $231,000 for the 207,730 options exercised during the three months ended March 31, 2021, which had an intrinsic value of $1.1 million, and received $18,000 for the 23,606 options exercised during the three months ended March 31, 2020, which had an intrinsic value of $25,000.

VAXART, INC. AND SUBSIDIARIES

Notes to the Condensed Consolidated Financial Statements (Unaudited)

The weighted average grant date fair value of options awarded in the three months ended March 31, 2021, was $5.46. Their fair values were estimated using the following assumptions:

Risk-free interest rate		1.02% - 1.07%
Expected term	5.87 - 6.07 Years
Expected volatility		122% - 124%
Dividend yield		—	%

No options were awarded in the three months ended March 31, 2020. 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 March 31,*
	*2021*		*2020*

Research and development	$	579	$	22
General and administrative		672		74
Total stock-based compensation	$	1,251	$	96

As of March 31, 2021, the unrecognized stock-based compensation cost related to outstanding unvested stock options was $13.3 million, which the Company expects to recognize over an estimated weighted average period of 2.55 years.

NOTE 11. Net Loss Per Share

The following table presents the calculation of basic and diluted net loss per share (in thousands, except share and per share amounts):

	*Three Months Ended March 31,*
	*2021*			*2020*

Net loss	$	(16,007	)	$	(1,297	)

Shares used to compute net loss per share – basic and diluted		115,422,628			60,677,145

Net loss per share – basic and diluted	$	(0.14	)	$	(0.02	)

No adjustment has been made to the net loss in the three months ended March 31, 2021 or 2020, as the effect would be anti-dilutive due to the net loss.

The following potentially dilutive securities were excluded from the computation of diluted weighted average shares outstanding because they would have been antidilutive:

	*Three Months Ended March 31,*
	*2021*		*2020*

Options to purchase common stock		6,834,510		1,773,779

Performance-based restricted stock units		—		36,132

Warrants to purchase common stock		622,942		33,023,381

Total potentially dilutive securities excluded from denominator of the diluted earnings per share computation		7,457,452		34,833,292

NOTE 12. Subsequent Events

Since March 31, 2021, the Company has issued 4,304,541 shares of common stock under the Sales Agreement (see Note 1) for net proceeds totaling $36.3 million.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our condensed consolidated financial statements and related notes included elsewhere in this in this Quarterly Report on Form 10-Q and with our audited consolidated financial statements included in our Annual Report on Form 10-K filed with the SEC on February 25, 2021. This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, which are subject to the “safe harbor” created by those sections. Forward-looking statements are based on our management’s beliefs and assumptions and on information currently available to our management. In some cases, you can identify forward-looking statements by terms such as “may,” “will,” “should,” “could,” “goal,” “would,” “expect,” “plan,” “anticipate,” “believe,” “estimate,” “project,” “predict,” “potential” and similar expressions intended to identify forward-looking statements and reflect our beliefs and opinions on the relevant subject. Our actual results could differ materially from those discussed in the forward-looking statements. Factors that could cause or contribute to these differences include those discussed below and in this Quarterly Report on Form 10-Q, particularly in the section entitled “Risk Factors” in Part II, Item 1A. The forward-looking statements included in this Quarterly Report on Form 10-Q are made only as of the date hereof. These statements are based upon information available to us as of the filing date of this Quarterly Report on Form 10-Q, and while we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain, and we caution investors against unduly relying upon these statements. In all events, we undertake no obligation to revise or update any forward-looking statements, whether as a result of new information, change in circumstances, future events or otherwise, and you are advised to consult any additional disclosures that we may make directly to you or through reports that we, in the future, may file with the SEC, including annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K.

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 for our Phase 1 clinical trial for our SARS CoV-2 vaccine candidate that commenced in October 2020 and 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 bivalent 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. Finally, we are focusing on the development of a coronavirus vaccine candidate utilizing our proprietary oral vaccine platform. 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 outbreak 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 outbreak 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, 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 office-based employees have been mostly working from home since mid-March 2020 and will continue to do so until we believe it is safe to return to the workplace. 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 outbreak may also be slowed or reversed by a number of factors, including the emergence of coronavirus strains with mutated S proteins 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. Janssen had an option to negotiate an exclusive license.

RSV program to be partnered with new antigen partner, pending which the program is 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”), in late 2019 an outbreak of COVID-19, caused by the virus SARS-CoV-2, began in Wuhan, China. The disease spread rapidly and person-to-person transmission has been widely documented. Stay-at-home orders or similar mandates were issued in all 50 states in the U.S. and throughout Europe and restrictions on certain activities, especially those involving large gatherings of people, remain in place, with regional variations. By May 5, 2021, more than 155 million COVID-19 cases had been identified in over 200 countries and territories worldwide, including the United States, where the CDC had reported over 32.3 million infections and 575,000 deaths.

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 plan to commence a Phase 2a study in the third quarter of 2021, with 24 participants aged 18 to 55 and 24 participants aged 56 to 75 years old, to further evaluate safety and immunogenicity and to assess optimal dosage.

●

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. Recently, we resumed this program by adding a second dose, which will be administered to participants in the Phase 1b norovirus trial more than 12 months after their first vaccination.

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 are currently completing the boost phase (second dose after 1 year) in the Phase 1b bivalent study. The next steps in the clinical development of our norovirus oral vaccine will include (i) the initiation of a Phase 1b placebo-controlled, dose ranging study in elderly adult subjects, and (ii) initiation of a boost (second dose) schedule optimization study in young adults. Additionally, a Phase 2 safety and dose confirmation study with Vaxart’s bivalent norovirus vaccine in subjects age 18 years and older is being planned. Lastly, the feasibility of a Phase 2 norovirus challenge study may also be considered; this study would possibly be conducted in parallel with the Phase 2 dose confirmation study. These set 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.

In addition to our conventional seasonal flu vaccine, we entered into a research collaboration agreement with Janssen 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. Janssen had an option to negotiate an exclusive worldwide license to our technology encompassing the Janssen antigens.

●

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.

Anti-Virals

●

Through the Merger, we acquired two royalty earning products, Relenza and Inavir.

●

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 have been earning 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 March 31,
	2021		2020
External program costs:
COVID-19 program	$	2,939	$	—
Norovirus program		454		112
All other programs		—		7
Preclinical research		422		121
Process development		1,106		—
Total external costs		4,921		240
Internal costs		5,152		1,302
Total research and development	$	10,073	$	1,542

We expect that research and development expenses will increase in 2021 and beyond 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 VXA-CoV2-1 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 and $99,000 in the three months ended March 31, 2021 and 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 March 31, 2021, we earned no royalty revenue, compared to $2.8 million earned in the three months ended March 31, 2020. 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 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 March 31, 2021, non-cash royalty revenue related to sale of future royalties was $493,000, compared to $34,000 in the three months ended March 31, 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, all of which was recognized as non-cash royalty revenue.

Total Operating Expenses

The following table presents our operating expenses for the three months ended March 31, 2021 and 2020 (in thousands, except percentages):

	Three Months Ended March 31,
	2021		2020		% Change
Research and development	$	10,073	$	1,542		553	%
General and administrative		5,944		1,990		199	%
Restructuring costs		—		64		(100	)%
Total operating expenses	$	16,017	$	3,596		345	%

Research and Development

For the three months ended March 31, 2021, research and development expenses increased by $8.5 million, or 553%, compared to the three months ended March 31, 2020. The increase 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 higher in 2021 than in 2020 as we expect significant expenditures on manufacturing and clinical trials for our COVID-19 and norovirus vaccine candidates.

General and Administrative

For the three months ended March 31, 2021, general and administrative expenses increased by $4.0 million, or 199%, compared to the corresponding period in 2020. The principal reasons are increased legal fees to defend ourselves against various shareholder lawsuits and class actions, additional directors and officers liability insurance costs and increased personnel costs, including stock-based compensation and facilities allocation, in line with our corporate growth.

Other Income and (Expenses)

The following table presents our non-operating income and expenses for the three months ended March 31, 2021 and 2020 (in thousands, except percentages):

	Three Months Ended March 31,
	2021			2020			% Change
Interest income	$	9		$	41			(78	)%
Non-cash interest expense related to sale of future royalties		(466	)		(491	)		(5	)%
Foreign exchange loss, net		(1	)		—			N/A
Net non-operating income and (expenses)	$	(458	)	$	(450	)		2	%

For the three months ended March 31, 2021, we recorded net non-operating expenses of $458,000, a 2% increase from the $450,000 recorded in the three months ended March 31, 2020.

Interest income decreased in 2021, despite higher cash balances, because rates of interest were lower. Non-cash interest expense related to sale of future royalties, which relates to accounting for sums that will become payable to HCRP for royalty revenue earned from Inavir as debt, decreased in 2021 as the outstanding balance due to HCRP has been paid down.

Provision for Income Taxes

The following table presents our provision for income taxes for the three months ended March 31, 2021 and 2020, respectively:

	Three Months Ended March 31,
	2021		2020		% Change
Foreign withholding tax on royalty revenue	$	25	$	140		(82	)%
Foreign taxes payable on intercompany interest		13		13		—	%
Provision for income taxes	$	38	$	153		(75	)%

The provision for income taxes comprises $38,000 and $153,000 in the three months ended March 31, 2021 and 2020, respectively. The majority 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 $2.7 million in the three months ended March 31, 2020 to $468,000 in the three months ended March 31, 2021. In addition, we incur charges relating to interest on an intercompany loan from a foreign subsidiary.

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. Most recently, in October 2020 we entered into an Open Market Sale Agreement, (the “Sales Agreement”) under which we may sell shares of our common stock having an aggregate offering price of up to $250 million.

As of March 31, 2021, we had $177.3 million of cash, cash equivalents and liquid investments. Since then, we have received net proceeds of $36.3 million from the sale of common stock under the Sales Agreement, with approximately $131 million in net proceeds still available to us.

We believe our existing funds are sufficient to fund us well into 2022 and possibly beyond. 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. We may also need to fund our operations through equity and/or debt financing. The sale of additional equity would result in additional dilution to our stockholders. Incurring debt financing 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.

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. See Note 7 to the Condensed Consolidated Financial Statements in Part I, Item 1 for further details.

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.

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 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 three 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 March 31, 2021, we had cash, cash equivalents and investments of $177.3 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.

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 of 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.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

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 March 31, 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 March 31, 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

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.
