The directors and executive officers of the Reporting Person are set forth on Schedule I, attached hereto. Schedule I sets forth the following information with respect to each such person:

(i) name;

(ii) business address;

(iii) position with the Reporting Person and present principal occupation or employment and, for persons not employed by the Reporting Person, the name, principal business and address of any corporation or other organization in which such employment is conducted; and

The total consideration for the Initial Purchase was $15.2 million, and such consideration was obtained from the available cash resources of Gilead.

CUSIP No. 0453961080

Item 4. Purpose of Transaction

On October 15, 2023, Gilead and the Issuer entered into an Option, License and Collaboration Agreement (the “Collaboration Agreement”) pursuant to which Gilead (1) exclusively licensed to the Issuer its helicase primase inhibitor program and non-nucleoside polymerase inhibitor (NNPI) program, while retaining opt-in rights to these programs and (2) has an option to take an exclusive license, on a program-by-program basis, to all of the Issuer’s other current and future pipeline programs.

In addition to the Collaboration Agreement, Gilead and the Issuer entered into a Common Stock Purchase Agreement (the “Purchase Agreement”) and an Investor Rights Agreement (the “Investor Rights Agreement” and, together with the Purchase Agreement, the “Equity Agreements”), pursuant to which Gilead made the Initial Purchase. If the Issuer completes an equity financing (or series of financings) by July 15, 2024 that results in at least $30 million of proceeds to the Issuer, then, subject to approval by the Issuer’s stockholders, the Issuer may require Gilead to purchase additional shares of Common Stock from the Issuer in an amount that results in Gilead owning 29.9% of the Issuer’s then-outstanding voting capital stock. If the Issuer does not complete the equity financing or does not provide notice to Gilead that it is requiring Gilead to purchase such additional shares, Gilead may elect to purchase additional shares of Common Stock from the Issuer in an amount that results in Gilead owning 29.9% of the Issuer’s then-outstanding voting capital stock, subject to Issuer stockholder approval. The purchase price per share for additional shares purchased by Gilead will be equal to the lesser of (1) a 35% premium to the 30-day volume weighted average price immediately prior to the date of purchase or (2) a 35% premium to the 30-day volume weighted average price immediately prior to delivery by Gilead of notice of the anticipated closing date for the additional share purchase. The Equity Agreements also include standstill and lockup provisions, with customary exceptions, and provide Gilead with certain other stock purchase rights and registration rights, as well as the right to designate two directors (or, alternatively, board observers, at Gilead’s election) to the Issuer’s Board of Directors.

The acquisitions by the Reporting Person of the Issuer’s securities as described herein were effected in connection with entry into the Collaboration Agreement and the Equity Agreements, and because of the belief that the securities of the Issuer represent an attractive investment. The foregoing description of the Equity Agreements is not complete and is subject to and qualified in its entirety by reference to the full text of such agreements, which are attached as Exhibits 99.1 and 99.2 hereto and incorporated herein by reference.

Except as otherwise described herein, the Reporting Person currently has no plan(s) or proposal(s) that relate to, or would result in, any of the events or transactions described in Item 4(a) through (j) of Schedule 13D, although the Reporting Person reserves the right, at any time and from time to time, to review or reconsider such position and/or change such purpose and/or formulate plans or proposals with respect thereto.

The Reporting Person intends to review from time to time its investment in the Issuer and the Issuer’s business affairs, financial position, performance and other investments considerations. The Reporting Person may from time to time engage in discussions with the Issuer, its directors and officers, other stockholders of the Issuer and other persons on matters that relate to the management, operations, business, assets, capitalization, financial condition, strategic plans, governance and the future of the Issuer and/or its subsidiaries. Based upon such review and discussions, as well as general economic, market and industry conditions and prospectus and the Reporting Person’s liquidity requirements and investment considerations, and subject to the limitations in the agreements described above, the Reporting Person may consider additional courses of action, which may include, in the future, formulating plans or proposals regarding the Issuer and/or its subsidiaries, including possible future plans or proposals concerning events or transactions of the kind described in Item 4(a) through (j) of Schedule 13D.
