("Company"), Gilead Sciences, Inc. ("Parent"), and Ravens Sub, Inc., a wholly owned subsidiary of Parent ("Purchaser"), the shares of common stock of Company that were tendered to Purchaser prior to the expiration time of the offer were exchanged for (x) $115.00 per share ("Closing Amount"), net to the seller in cash, without interest, subject to withholding tax, plus (y) one contractual contingent value right (a "CVR"), which represents the right to receive one contingent payment of $5.00 per CVR in cash, without interest, and subject to any withholding tax, pursuant to the terms and subject to the conditions of a contingent value rights agreement. After completion of the tender offer, pursuant to the terms of the Merger Agreement, Purchaser merged with and into Company (the "Merger"), with Company surviving the Merger as a wholly owned subsidiary of Parent. The Reporting Person is a trustee of the Ali Behbahani Revocable Trust Dated June 26, 2015 (the "Behbahani Trust"), which is the direct beneficial owner of the securities. The Reporting Person disclaims beneficial ownership within the meaning of Section 16 of the 1934 Act, as amended, or otherwise of such portion of the securities held by the Behbahani Trust in which the Reporting Person has no pecuniary interest. Pursuant to the Merger Agreement, each outstanding option to purchase shares of Common Stock (a "Company Option"), whether or not vested, and which had a per share exercise price that was less than the Closing Amount, was canceled and converted into the right of the holder to receive (i) (subject to any applicable withholding taxes) a lump-sum cash payment equal to (x) the excess (if any) of (a) the Closing Amount over (b) the per share exercise price subject to such Company Option, multiplied by (y) the total number of shares subject to such Company Option immediately prior to the effective time of the Merger, and (ii) one (1) CVR for each share subject to such Company Option immediately prior to the effective time of the Merger. /s/ Nicole Hatcher, attorney-in-fact 2026-04-28
