As previously disclosed, on February 22, 2026, Gilead entered into an Agreement and Plan of Merger (the "<u>Merger Agreement</u>"), among Parent, the Company and Ravens Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of Parent ("<u>Purchaser</u>"). In accordance with the terms of the Merger Agreement, on April 28, 2026, Gilead completed the acquisition of the Company.

Pursuant to the Merger Agreement, and upon the terms and subject to the conditions thereof, on March 6, 2026, Purchaser commenced a tender offer (the "<u>Offer</u>"), to purchase all of the issued and outstanding shares (the "<u>Shares</u>") of common stock, par value $0.001 per share, of the Company (other than any Shares owned immediately prior to the effective time of the Merger (as defined below) by the Company (including those held in the Company's treasury), and any Shares owned both as of the date of the commencement of the Offer and immediately prior to the effective time of the Merger by Parent, Purchaser or any other direct or indirect wholly owned subsidiary of Parent, at a price per Share of (i) $115.00 per Share (the "<u>Closing Amount</u>"), net to the seller in cash, without interest, subject to any withholding tax, *plus* (ii) one contractual contingent value right (a "<u>CVR</u>"), which represents the right to receive one contingent payment of $5.00 per CVR, in cash, without interest, and subject to any withholding tax, payable on March 31, 2030, subject to cumulative worldwide Sales (as defined in the CVR Agreement (as defined below)) of the Company's anitocabtagene autoleucel (anito-cel) product exceeding $6.0 billion on or prior to December 31, 2029 and the other terms and conditions set forth in a contingent value rights agreement (the "<u>CVR Agreement</u>"), entered into by and among Parent, Computershare, Inc., a Delaware corporation, and its affiliate, Computershare Trust Company, N.A., a federally chartered trust company.

The Offer expired at 5:00 p.m., Eastern Time, on April 27, 2026 (the ''Expiration Time''). According to Computershare Trust Company, N.A., the depositary and paying agent for the Offer, as of the Expiration Time, 38,795,604 Shares were validly tendered and not validly withdrawn in the Offer, representing, together with Shares already owned by Parent, approximately 77.2% of the outstanding Shares. The number of Shares tendered satisfied the condition to the Offer that there be validly tendered, and not validly withdrawn, in the Offer a number of Shares that, considered together with all other Shares owned by Purchaser and its affiliates (as such term is defined in Section 251(h)(6) of the General Corporation Law of the State of Delaware (the "<u>DGCL</u>")), represent one more Share than 50% of the total number of Shares outstanding at the Expiration Time. All conditions to the Offer having been satisfied or waived, Gilead and Purchaser accepted for payment all Shares validly tendered and not validly withdrawn.

Following the consummation of the Offer, the remaining conditions to the Merger set forth in the Merger Agreement were satisfied or waived, and on April 28, 2026, Purchaser merged with and into the Company (the "<u>Merger</u>") pursuant to Section 251(h) of the DGCL, with the Company continuing as the surviving corporation and a wholly owned subsidiary of Parent. Each Share outstanding immediately prior to the effective time of the Merger (other than (i) Shares owned immediately prior to the effective time of the Merger by the Company (including those held in the Company's treasury), (ii) Shares owned both as of the commencement of the Offer and immediately prior to the effective time of the Merger by Parent, Purchaser, or any other direct or indirect wholly owned subsidiary of Parent, (iii) Shares irrevocably accepted for purchase pursuant to the Offer and (iv) Shares held by stockholders who are entitled to appraisal rights under Section 262 of the DGCL and have properly exercised and perfected their respective demands for appraisal of such Shares in the time and manner provided in Section 262 of the DGCL and, as of the effective time of the Merger, have neither effectively withdrawn nor lost their rights to such appraisal and payment under the DGCL) was converted into the right to receive, on a per Share basis, (i) the Closing Amount in cash, without any interest thereon, subject to any withholding tax, *plus* (ii) one CVR per Share.

The aggregate amount of funds used by Gilead to consummate the Offer and Merger (including payments for options, restricted stock units and other payments referred to in the Merger Agreement) was approximately $7.1 billion.

**GILEAD SCIENCES COMPLETES ACQUISITION OF ARCELLX AHEAD OF POTENTIAL COMMERCIAL LAUNCH OF ANITO-CEL**

**FOSTER CITY, Calif., April 28, 2026** – Gilead Sciences, Inc. (Nasdaq: GILD) today announced the successful completion of its <u>previously announced</u> acquisition of Arcellx, Inc. (Nasdaq: ACLX). Under the terms of the transaction, Gilead acquired Arcellx for $115 per share in cash, plus one non-transferable contingent value right (CVR) of $5 per share, representing a total implied equity value of approximately $7.8 billion at the time of closing.

The acquisition builds on Kite, a Gilead Company, and Arcellx's successful collaboration and provides Gilead with full control of anitocabtagene autoleucel (anito-cel), an investigational BCMA-directed CAR T-cell therapy for multiple myeloma. By consolidating ownership of anito-cel and eliminating future profit-share, milestone and royalty obligations, Gilead is positioned to accelerate development, streamline decision-making and maximize the long-term potential of the program.

"With the Arcellx acquisition, our focus turns to executing with speed and discipline as we prepare to bring anito-cel to patients," said Cindy Perettie, Executive Vice President and Global Head of Kite. "I want to thank the Arcellx team for their scientific leadership, close collaboration to date and deep expertise they bring as we advance anito-cel. With this acquisition, anito-cel and the differentiated D-Domain BCMA binder will advance within Kite, combining this science with our global manufacturing, regulatory and commercial capabilities to unlock the full value of this potentially transformative therapy for people living with multiple myeloma."

On April 28, 2026, Gilead successfully completed its tender offer for all outstanding shares of common stock of Arcellx and accepted for payment all shares validly tendered and not validly withdrawn as of the expiration time of the tender offer, which shares represented, together with shares already owned by Gilead, approximately 77.2% of Arcellx's outstanding shares. Following completion of the offer, Gilead completed the acquisition of Arcellx through a merger of Gilead's wholly owned subsidiary with and into Arcellx, in which shares of Arcellx common stock were cancelled and converted into the right to receive the same $115 per share in cash and one CVR of $5 per share as shares tendered in the offer.

The CVR is payable upon achievement of cumulative global net sales of anito-cel of at least $6.0 billion from launch through the end of 2029.

As a result of the completion of the merger, Arcellx has become a wholly owned subsidiary of Gilead and the common stock of Arcellx will be delisted from the Nasdaq Global Select Market.

This transaction is expected to be accounted for as an asset acquisition and reduce Gilead's GAAP and non-GAAP 2026 diluted EPS by approximately $5.57 - $5.67. Excluding the impact of acquired in-process research and development expenses, Gilead expects the transaction to be modestly dilutive to earnings per share in 2026 and 2027, and accretive in 2028 and thereafter, subject to FDA approval of anito-cel.

**<u>About Anito-cel</u>**

Anitocabtagene autoleucel (anito-cel, previously ddBCMA) is the first BCMA-directed CAR T-cell therapy to be investigated in multiple myeloma that utilizes a novel and compact binder known as the D-Domain. The small, stable D-Domain binder enables high CAR expression without tonic signaling and is designed to quickly release from the BCMA target. This combination may allow for the effective elimination of multiple myeloma cells without severe immunotoxicity. Anito-cel has been granted Fast Track, Orphan Drug, and Regenerative Medicine Advanced Therapy Designations by the U.S. Food and Drug Administration.
