February 2026
Arcellx 23-Feb-2026
Acquirer: Gilead Sciences
Total deal value: US$7.8B implied equity value (payable at closing) | Upfront: US$115/share cash (+ US$5/share CVR contingent)
Structure: Tender offer + second-step merger (all-cash + CVR) | Type: Public | 1D Premium: 68% (to 30-day VWAP)
Therapeutic area: Oncology / Hematology | Stage / lead assets: BLA accepted anito-cel (anitocabtagene autoleucel; ddBCMA CAR-T) for relapsed/refractory multiple myeloma
Why it matters: Gilead buys out its partner to take full control/economics of anito-cel ahead of a potential launch, accelerating development + commercialization while eliminating the existing profit-share, milestones, and royalties.
Orna Therapeutics 09-Feb-2026
Acquirer: Eli Lilly and Company
Total deal value: Up to US$2.4B (cash; upfront + clinical development milestones) | Upfront: Undisclosed
Structure: Acquisition (cash upfront + contingent clinical milestone payments) | Type: Private
Therapeutic area: Autoimmune / Immunology (in vivo cell therapy) | Stage / lead assets: ORN-252 (CD19) in vivo CAR-T (clinical-trial-ready / preclinical)
Why it matters: Lilly’s entry into in vivo CAR-T—aiming to turn cell therapy from a bespoke, ex vivo manufacturing model into something more scalable (and potentially usable across broader autoimmune indications).
January 2026
Surf Bio 28-Jan-2026
Acquirer: Halozyme Therapeutics
Total deal value: Up to US$400M | Upfront: US$300M (subject to customary purchase price adjustments)

Therapeutic area: Drug delivery / formulation platform | Stage / lead assets: “Hyperconcentration” formulation tech enabling ultrahigh drug concentrations (reported up to ~500 mg/mL) for single-shot SC delivery via standard autoinjectors
Why it matters: Broadens Halozyme’s delivery stack beyond ENHANZE, adding a differentiated formulation capability that could expand the set of biologics feasible for at-home SC dosing and support additional partnering/royalty pathways.
Note: acquisition completed in late Dec 2025; first publicly disclosed 28-Jan-2026.
RAPT Therapeutics 20-Jan-2026
Acquirer: GSK
Total deal value: US$2.2B ($1.9B net of cash acquired) | Upfront: US$2.2B

Therapeutic area: Allergy / Immunology | Stage / lead assets: Phase 2b ozureprubart (long-acting anti-IgE mAb) for prophylactic protection against food allergens
