Arcellx Inc's stock surged 78.13% in pre-market trading, reaching a 52-week high, following Gilead's announcement of its acquisition agreement.
Gilead Sciences has entered into a definitive agreement to acquire Arcellx for $115 per share in cash, totaling $7.8 billion. This acquisition reflects Gilead's confidence in Arcellx's innovative therapies, particularly the potential FDA approval of Anito-cel for multiple myeloma, which is expected to enhance Gilead's market position significantly. The deal is anticipated to close in Q2 2026, with Gilead projecting an increase in earnings per share starting in 2028, driven by the expected success of Anito-cel.
The acquisition is seen as a strategic move for Gilead, solidifying its leadership in oncology and expanding its portfolio in blood cancer treatments. The strong market reaction to the acquisition indicates heightened investor interest in Arcellx, which may lead to further stock price appreciation.

About ACLX
Arcellx Inc. is a clinical-stage biotechnology company reimagining cell therapy by engineering immunotherapies for patients with cancer and other incurable diseases. Its lead program is a BCMA-targeting ddCAR product candidate called anitocabtagene autoleucel, which is being evaluated in its pivotal Phase II iMMagine-1 and the Phase III iMMagine-3 trials in patients with relapsed or refractory multiple myeloma (rrMM). Anitocabtagene is the first BCMA-directed CAR T-cell therapy to be investigated in multiple myeloma that utilizes its 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. It is also developing two clinical-stage ARC-SparX programs in Phase I trials: ACLX-001, which targets BCMA in rrMM, and ACLX-002, which targets CD123 in relapsed or refractory acute myeloid leukemia (AML) and high-risk myelodysplastic syndrome (MDS).

Arcellx Executive Sells $10.24 Million in Shares Amid Acquisition
- Executive Stock Sale: Rami Elghandour, President of Arcellx, sold 89,916 shares for approximately $10.24 million on February 27, 2026, indicating a potential shift in confidence despite retaining 276,051 shares directly and 416,500 shares indirectly.
- Sale Size Comparison: This sale is significantly larger than Elghandour's historical median sell size of 38,300 shares since January 2025, suggesting he may be adjusting his portfolio or adopting a cautious outlook on the company's future.
- Market Performance and Acquisition Dynamics: While Arcellx's stock has surged 75.55% over the past year, the company announced its acquisition by Gilead Sciences for approximately $7.8 billion, with a purchase price of $115 per share, indicating an impending delisting of the stock.
- Clinical Progress and Future Potential: Arcellx has recently achieved a breakthrough in its multiple myeloma treatment, advancing to Phase 2 development, and if its blood cancer immunotherapy receives FDA approval, it could generate significant revenue, yet the approaching merger introduces uncertainty for investors.
