Aviragen Therapeutics, Inc. (NASDAQ:AVIR) Files An 8-K Entry into a Material Definitive Agreement

Aviragen Therapeutics, Inc. (NASDAQ:AVIR) Files An 8-K Entry into a Material Definitive AgreementItem 1.01

As of December 31, 2017 and June 30, 2017, the Company had investments in an unrealized gain (loss) position below material disclosure thresholds in the table above. The Company determined that the unrealized gains and losses on these investments were temporary in nature and expected the security to mature at its stated maturity principal. All available-for-sale securities held at December 31, 2017, will mature in less than one year. The fair value of cash, accounts receivable, accounts payable and accrued liabilities approximate their carrying value because of the short-term nature of these financial instruments at December 31, and June 30, 2017, respectively. The fair value of the Companys short-term note payable, which is measured using Level inputs, approximates book value, at December 31, and June 30, 2017.

() Accrued and Other Current Liabilities

Accrued expenses consist of the following (in millions):

()Liabilities Related to Sale of Future Royalties

In April 2016, the Company sold certain royalty rights related to the approved product Inavir, sold by Daiichi Sankyo Company, Limited (Daiichi Sankyo) in the Japanese market, for $20 million to HealthCare Royalty Partners III, L.P. (HCRP). Under the relevant accounting guidance, due to a limit on the amount of royalties that HCRP can earn under the arrangement, this transaction was accounted for as a liability that will be 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 with Daiichi Sankyo and the payments that will be passed through to HCRP over the life of the agreement. The sum of the pass through amounts less the net proceeds received will be recorded as non-cash interest expense over the life of the liability. 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 Company will periodically assess the expected royalty payments, and to the extent such payments are greater or less than the initial estimate, the Company will adjust the amortization of the liability and interest rate. As a result of this accounting, even though the Company does not retain HCRPs share of the royalties, it will continue to record non-cash revenue related to those royalties until the amount of the associated liability and related interest is fully amortized.

Table of Contents

The following table shows the activity within the liability account during the six months ended December 31, 2017:

() Net Loss per share

Basic and diluted net loss per share has been computed based on net loss and the weighted-average number of common shares outstanding during the applicable period. For diluted net loss per share, common stock equivalents (shares of common stock issuable upon the exercise of stock options and unvested restricted stock units) are excluded from the calculation as their inclusion would be anti-dilutive. The Company has excluded all anti-dilutive share-based awards to purchase common stock in periods indicating a loss, as their effect is anti-dilutive.

The following tables set forth the computation of historical basic and diluted net loss per share.

Royalty agreements

The Company entered into a royalty-bearing research and license agreement with GlaxoSmithKline (GSK) in for the development and commercialization of zanamivir, a neuraminidase inhibitor marketed by GSK as Relenza to treat influenza. Under the terms of the agreement, the Company licensed zanamivir to GSK on an exclusive, worldwide basis. Most of the Companys Relenza patents have expired and the only substantial remaining intellectual property related to the Relenza patent portfolio is scheduled to expire in July 2019 in Japan. Until that patent expires, the Company will receive a 7% royalty on GSKs annual net sales of Relenza in Japan.

The Company also generates royalty revenue from the sale of Inavir (laninamivir octanoate or LANI) in Japan, to a collaboration and license agreement and a related commercialization agreement (collectively, the Inavir License Agreement) with Daiichi Sankyo. Under the Inavir License Agreement, the Company currently receives a 4% royalty on net sales of Inavir in Japan and is eligible to earn sales milestone payments. Under the Inavir License Agreement, the Company and Daiichi Sankyo have cross-licensed the world-wide rights to develop and commercialize the related intellectual property, and have agreed to share equally in any royalties, license fees, or milestone or other payments received from any third party licenses outside of Japan. The patent relating to hydrates and the crystalline form of LANI used in Inavir expires in (not including extensions) in the U.S. and EU and in in Japan. In February 2015, a patent containing claims relevant to the manufacture of Inavir was issued in Japan and expires in December 2029.

In April 2016, the Company entered into a Royalty Interest Acquisition Agreement (Agreement) with HCRP. Under the Agreement, HCRP made a $20 million cash payment to the Company in consideration for acquiring from the Company certain royalty rights (Royalty Rights) related to Inavir in the Japanese market.

The following tables summarize the key components of the Companys revenues (in millions):

Relenza revenue declined to zero in the three and six months ended December 31, 2017 from $1.5 million in the same periods of the prior fiscal year due to the cessation of royalties on U.S. sales at the end of 2016 and the unfavorable impact of a returns adjustment in the current quarter.

Collaborative and contract arrangements

In July 2016, the Company entered into an exclusive, worldwide license for RSV replication inhibitors intellectual property with Georgia State University Research Foundation (GSURF) in exchange for an upfront fee, future milestone payments and royalties on future net sales of any products that utilize the underlying RSV intellectual property. The Company has an obligation to make a minimum payment of $10,000 to GSURF annually until the license agreement expires or is terminated. The Company also entered into a two year sponsored research agreement with GSURF for annual sponsored research payments.

Table of Contents

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the Tax Act). The Tax Act significantly revises the future ongoing U.S. corporate income tax by, among other things, lowering U. S. corporate income tax rates and implementing a territorial tax system. Since the Company is a calendar year tax filer, the lower corporate income tax rate will be effective beginning January 1, 2018.

Based upon the provisions of the Tax Act, the Companys deferred tax assets and liabilities will be remeasured to incorporate the lower corporate tax rate of 21% into its tax provision; however, since the Company maintains a full valuation allowance, there is no net impact to income tax expense reported in the Companys financial statements for the periods presented as the provisional valuation allowance will be adjusted accordingly. At this time, the Company is still evaluating the impact of this remeasurement.

There are also certain transitional impacts of the Tax Act. As part of the transition to the new territorial tax system, the Tax Act imposes a one-time repatriation tax on deemed repatriation of historical earnings and profits (EP) of foreign subsidiaries. Due to the complexity of this calculation and the information required to complete such a calculation, the Company is still reviewing its EP from our foreign subsidiaries in connection with the one-time transition tax.

The Company is also currently analyzing its global working capital and cash requirements and the potential tax liabilities attributable to a repatriation, including calculating any excess of the amount for financial reporting over the tax basis in its foreign subsidiaries, but has yet to determine whether it plans to change its prior assertion and repatriate earnings. Accordingly, the Company has not recorded any deferred taxes attributable to its investments in its foreign subsidiaries. The Company will record the tax effects of any change in its prior assertion in the period that it completes its analysis and are able to make a reasonable estimate, and disclose any unrecognized deferred tax liability for temporary differences related to its foreign investments, if practicable.

The changes included in the Tax Act are broad and complex. The final transition impacts of the Tax Act may affect our financial statements and/or disclosures, possibly materially, due to, among other things, changes in interpretations of the Tax Act, any legislative action to address questions that arise because of the Tax Act, any changes in accounting standards for income taxes or related interpretations in response to the Tax Act. The Securities Exchange Commission has issued rules that would allow for a measurement period of up to one year after the enactment date of the Tax Act to finalize the recording of the related tax impacts.

The following is a discussion and analysis of the major factors contributing to ourresults of operations for the three and six months ended December 31, 2017, and our financial condition at that date, and should be read in conjunction with the financial statements and the notes thereto included in Part I, Item 1 of this Quarterly Report on Form 10-Q.

Company Overview

We are focused on the discovery and development of direct-acting antivirals to treat infections that have limited therapeutic options and affect a significant number of patients globally. The Company has three Phase 2 clinical stage compounds: BTA074 (teslexivir), an antiviral treatment for condyloma caused by human papillomavirus types 6 11; vapendavir, a capsid inhibitor for the prevention or treatment of rhinovirus (RV) upper respiratory infections; and BTA585 (enzaplatovir), a fusion protein inhibitor in development for the treatment of respiratory syncytial virus infections.

Although several of our influenza product candidates have been successfully developed and commercialized to date by other larger pharmaceutical companies under license, collaboration or commercialization agreements with us, we have not independently developed or received regulatory approval for any product candidate, and we do not currently have any sales, marketing or commercial capabilities. Therefore, it is possible that we may not derive any significant product revenues from any product candidates that we are developing now, or may develop in the future. We expect to incur losses for the foreseeable future as we intend to support the clinical and preclinical development of our product candidates.

On October 30, 2017, the Company announced that it had entered into the Merger Agreement to which Vaxart, a privately-held clinical-stage company focused on developing oral recombinant vaccines from its proprietary delivery platform, would become a wholly-owned subsidiary of the Company. This transaction marks the culmination of the Companys Strategic Review process which was initiated in April. The Merger will result in a clinical-stage pharmaceutical company focused on developing Vaxarts oral recombinant vaccines and our direct-acting antivirals to treat infections that have limited therapeutic options. We believe Vaxarts oral tablet vaccines have the potential to be major products in the worldwide vaccine market.

The exchange ratio in the merger agreement was determined by Vaxart assigning $60,000,000 in value to Aviragen for its financial and clinical assets, and $90,000,000 in value for its own assets. On a pro forma basis after giving effect to the number of shares of Aviragen common stock that will be issued to Vaxart security holders in the Merger and assuming no adjustments for cash balances as provided for in the Merger Agreement, current Vaxart security holders will own approximately 60% of the combined company and current Aviragen security holders will own approximately 40% of the combined company. The transaction has been approved by the boards of directors of both companies. The Merger is expected to close in February 2018, subject to the approval of the stockholders of each company as well as other customary conditions.

At the end of the quarter, a small group of dissident stockholders, who call themselves the Concerned Aviragen Shareholders (CAS) Group, launched a proxy contest against the proposed merger with Vaxart and are seeking an opportunity to nominate individuals for election to the Companys Board at our upcoming Annual Meeting. We continue to believe the proposed merger with Vaxart is the best possible strategic alternative, and together, Aviragen and Vaxart will have the potential to create meaningful value for stockholders.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Managements Discussion and Analysis of Results of Operations discusses our financial results, which (except to the extent described in the Notes thereto) have been presented in accordance with U.S. generally accepted accounting principles (U.S. GAAP). The preparation of financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.

Table of Contents

We base our estimates and judgments on historical experience, current economic and industry conditions, and various other factors that we believe to be reasonable under the circumstances. This forms the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. We believe there have been no changes to our critical accounting policies that require significant judgment and estimates as discussed in detail in our 2017 annual 10-K filing:

For a description of recent accounting policies and the impact on our financial statements, refer to Note 2 in the condensed consolidated financial statements.

Results of Operations for the Three months ended December 31, 2017 and December 31, 2016

Summary. For the three months ended December 31, 2017, we reported a net loss of $3.4 million, as compared to a net loss of $9.1 million in the same period of the prior fiscal year. Basic and diluted net loss per share was $0.09 for the three month period ended December 31, 2017, as compared to a basic and diluted net loss per share of $0.24 in the same period of 2016. The following commentary provides details underlying changes from last year in the major line items of our statement of operations:

Revenue. Revenue decreased to $2.7 million for the three month periods ended December 31, 2017, as compared to $3.8 million in the same period in 2016, mostly due to a decrease in our Relenza royalties. Relenza revenue declined to zero in the three months ended December 31, 2017 from $1.5 million in the same period of the prior fiscal year due to the cessation of royalties on U.S. sales at the end of 2016 and the unfavorable impact of a returns adjustment in the current quarter. The following table summarizes the key components of our revenue for the three months ended December 31, 2017 and 2016:

Research and Development Expense. Research and development expense decreased to $2.5million for the three months ended December 31, 2017 from $10.2 million for the same period in 2016. The following table summarizes the components of our research and development expense for the three months ended December 31, 2017 and 2016.

Table of Contents

Direct preclinical, clinical and product development expense decreased largely due to reduced clinical trial activity and manufacturing costs, as two of our three Phase 2 clinical trials came to a close at the end of the prior fiscal year. Salaries, severance and share-based compensation expenses did not change as compared to the same period in 2016, as decreases due to reductions in personnel in the last quarter of the prior fiscal year were offset by severance expense for employees terminated in the current quarter.

General and Administrative Expense. General and administrative expenseincreased to $3.1million for the three months ended December 31, 2017 from $2.1 million for the same period in 2016, largely due to legal and professional fees related to the proposed merger with Vaxart announced in October 2017 and severance due to a reduction in personnel. The following table summarizes the components of our general and administrative expense for the three months ended December 31, 2017 and 2016.

Foreign Exchange Loss (Gain), net. The impact of foreign exchange changed from a loss of $0.1 million in December 31, 2016 to no gain or loss for three months ended December 31, 2017. The positive impact on foreign exchange on our statement of operations was due to fluctuations in foreign currency exchange rates versus the U.S. dollar, largely related to the British Pound and Australian dollar. The vast majority of our cash holdings are held in the U.S. dollar. We re-measure all of our foreign assets and liabilities at the period-end exchange rate and the net effect of these translation adjustments is shown as a foreign currency loss or gain.

Results of Operations for the Six months ended December 31, 2017 and December 31, 2016

Summary. For the six months ended December 31, 2017, we reported a net loss of $8.7 million, as compared to a net loss of $19.1 million in the same period of the prior fiscal year. Basic and diluted net loss per share was $0.23 for the six month period ended December 31, 2017, as compared to a basic and diluted net loss per share of $0.49 in the same period of 2016. The following commentary provides details underlying changes from last year in the major line items of our statement of operations:

Table of Contents

Revenue. Revenue decreased to $2.8 million for the six month periods ended December 31, 2017, as compared to $3.9 million in the same period in 2016, mostly due to a decrease in our Relenza royalties. Relenza revenue declined to zero in the six months ended December 31, 2017 from $1.6 million in the same period of the prior fiscal year due to the cessation of royalties on U.S. sales at the end of 2016 and the unfavorable impact of a returns adjustment in the current year. The following table summarizes the key components of our revenue for the six months ended December 31, 2017 and 2016:

Research and Development Expense. Research and development expense decreased to $5.3million for the six months ended December 31, 2017 from $17.8 million for the same period in 2016. The following table summarizes the components of our research and development expense for the six months ended December 31, 2017 and 2016.

Direct preclinical, clinical and product development expense decreased largely due to reduced clinical trial activity and manufacturing costs, as two of our three Phase 2 clinical trials came to a close at the end of the prior fiscal year. Salaries, severance and share-based compensation expenses decreased compared to the same period in 2016 due to a reduction in personnel in the last quarter of the prior fiscal year, partially offset by severance expense for employees terminated in the current year.

General and Administrative Expense. General and administrative expenseincreased to $5.4million for the six months ended December 31, 2017 from $4.3 million for the same period in 2016, largely due to legal and professional fees related to the proposed merger with Vaxart announced in October 2017 and severance due to a reduction in personnel. The following table summarizes the components of our general and administrative expense for the six months ended December 31, 2017 and 2016.

LIQUIDITY AND CAPITAL RESOURCES

For the six months ended December 31, 2017, cash and cash equivalents increased by $11.7 million. This increase was primarily the result of the maturities of our short-term investments.

Net cash used by operating activities was $9.2 million for the six months ended December 31, 2017, which reflected our net loss during the period of $8.7 million, a net decrease in a net operating assets of $0.5 million and a decrease in operating liabilities of $0.1 million, partially offset by net non-cash adjustments of $1.1 million. Non-cash adjustments consist of $2.7 million in non-cash royalty income, net of withholding taxes, partially offset by $0.8 million in non-cash interest expense and $0.8 million in share-based compensation expense.

Table of Contents

Our net loss resulted largely from our funding of research and development activities including conducting the CT4 clinical trial for BTA074 (teslexivir), as well as ongoing general and administrative expenses including legal and professional fees related to the proposed merger with Vaxart. The net changes in operating assets and liabilities primarily reflects a $0.1 million decrease in accounts payable and accrued expense due to reduced clinical trial activity, offset by a $0.2 million decrease in prepaid expenses, also due to reduced clinical trial activity and a $0.3 million decrease in cash receivables primarily related to receipt of a research and development tax credit.

Net cash provided by investing activities during the six months ended December 31, 2017 consisted ofthe maturity of $27.9 million of investments, partially offset by the purchase of $7.0 million of investments.

At December 31, 2017, our cash and cash equivalents totaled $29.4 million. Our cash and cash equivalents are currently held in the form of short-term deposits with large U.S. banks, commercial paper and highly-rated corporate securities.

Based on our current strategy and operating plan, and considering the potential costs associated with advancing the preclinical and clinical development of our product candidates, we believe that our existing cash and cash equivalents of approximately $29.4 million as of December 31, 2017, along with the anticipated proceeds from existing royalty-bearing licenses will enable us to operate for a period of at least 12 months from the date of this report.

We have an ATM facility in place, which may allow us to quickly access the equity capital markets if we think it is prudent to do so and if market conditions allow. However, we currently do not have any commitments for future funding, nor do we anticipate that we will generate significant revenue, aside from revenue from existing royalty-bearing arrangements.

Contractual and Commercial Commitments

There have been no material changes from the information included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2017.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements, as defined in Item303(a)(4) (ii)of Regulation S-K under the Securities Exchange Act of 1934, as amended.

ITEM 3: Quantitative and Qualitative Disclosures about Market Risk

There has been no material change in our assessment of sensitivity to market risk since our presentation set forth in Item 7A Quantitative and Qualitative Disclosures about Market Risk in the our Annual Report on Form 10-K for the fiscal year ended June 30, 2017.

PART II OTHER INFORMATION

ITEM1. LEGAL PROCEEDINGS

The Company is involved in various legal proceedings that are incidental to the conduct of its business. The Company is not involved in any pending or threatened legal proceedings that it believes could reasonably be expected to have a material adverse effect on its financial condition or results of operations.

ITEM 1A. RISK FACTORS

Any investment in our business involves a high degree of risk. Before making an investment decision, you should carefully consider the information we include in this Quarterly Report on Form 10-Q, including our condensed consolidated financial statements and accompanying notes, and the additional information in the other reports we file with the Securities and Exchange Commission along with the risks described in our Annual Report on Form 10-K for the fiscal year ended June 30, 2017. The Company is also subject to the risk factors set forth under the captions Risks Related to the Merger, Risks Related to Aviragen and Risks Related to the Combined Company in the Prospectus that is part of the Registration Statement on Form S-4 (File No. 333-222009), as amended, filed with the Securities and Exchange Commission by the Company and declared effective on December 29, 2017. We have also described below those risks that reflect substantive changes from, or additions to, the risks described in our Annual Report on Form 10-K and Form S-4, as amended, referred to above. These risks may result in material harm to our business and our financial condition and results of operations. In this event, the market price of our common stock may decline and you could lose part or all of your investment.

We may be subject to the actions of activist shareholders.

We have been the subject of increased activity by activist shareholders, including Digirad Corporation, East Hill Management Company, LLC, Thomas M. Clay, and certain other investors (collectively, the Activist Group). Responding to shareholder activism can be costly and time-consuming, disrupt our operations and divert the attention of management and our employees. Activist campaigns, including the Activist Groups ongoing campaign against our proposed transaction with Vaxart and the Activist Groups notice of its intention to nominate a competing director slate for election at our annual stockholder meeting scheduled for April 11, 2018, can create uncertainties as to our future direction, strategy and leadership and may result in the loss of potential business opportunities and cause our stock price to experience periods of volatility. Moreover, if individuals are elected to our board of directors with a specific agenda, our ability to effectively and timely implement our current initiatives, retain and attract experienced executives and employees and execute on our current business strategy may be adversely affected.
