Therapeutic area
Vaccines / Infectious disease / Shingles
Stage / lead assets
Amezosvatein, a next-generation shingles vaccine candidate designed to improve tolerability versus existing shingles vaccines
Why it matters

Part of Lilly's three-deal push back into infectious disease prevention. Curevo gives Lilly a clinically advanced shingles vaccine challenger with a tolerability-led positioning angle — a reminder that vaccine M&A can be strategic again when the asset targets large adult populations and could improve adherence versus entrenched incumbents.

Vaccines / Infectious disease / Epstein-Barr virus
Stage / lead assets
Phase 1-ready five-antigen Epstein-Barr virus vaccine candidate, plus broader virus-like particle vaccine technology
Why it matters

The highest-value of Lilly's three vaccine acquisitions and strategically notable because EBV biology sits at the intersection of infectious disease, neurology, and oncology risk. For investors, the read-through is that Big Pharma may again underwrite prevention platforms where the pathogen has links to long-term, high-cost disease rather than only acute infection.

Stage / lead assets
LTB-SA7, a Phase 1 vaccine candidate against Staphylococcus aureus, plus additional bacterial-pathogen vaccine programs
Why it matters

Adds bacterial-vaccine capability to Lilly's revived infectious-disease franchise. The strategic signal is that pharma appetite is not limited to viral vaccines: prevention of high-burden bacterial complications such as surgical-site infections can still attract M&A if the platform creates a pipeline of pathogen-specific shots.

Commercial specialty-pharma and rare-disease portfolio
Why it matters

A sponsor-led specialty-pharma take-private rather than a pipeline biotech takeout, but too large to ignore. The deal shows that private capital remains willing to underwrite scaled commercial biopharma assets with rare-disease exposure, even where the strategic logic is portfolio durability, operating control, and delisting rather than single-asset R&D upside.

IBC101, an autologous CD19xCD22 bivalent CAR-T for relapsed/refractory B-cell malignancies; INC101 preclinical dual-antigen CAR-T
Why it matters

A smaller and higher-risk public-acquirer / private-target transaction, but relevant as a recapitalization-style oncology platform deal. Liminatus is using stock to pivot toward CAR-T optionality despite limited cash, showing how distressed or microcap biotechs may use M&A to rebuild pipeline narratives when conventional financing remains constrained.

Genetic medicine / Non-viral DNA delivery
Stage / lead assets
Tethosome non-viral DNA delivery platform for genetic medicines
Why it matters

A platform tuck-in that extends Lilly's genetic-medicine toolkit rather than adding a near-term clinical asset. The read-through is that delivery remains a strategic bottleneck: large pharmas are willing to buy enabling technologies that could improve potency, tolerability, redosing, or tissue localization across broader genetic-medicine portfolios.

FIRDAPSE for Lambert-Eaton myasthenic syndrome
Why it matters

Angelini is using M&A to enter the U.S. market and scale its brain-health / rare-disease presence around a commercial neuromuscular platform. The read-through is that commercial rare-disease assets with concentrated specialist infrastructure remain strategic — particularly for ex-U.S. buyers seeking a U.S. beachhead rather than building one organically.

Why it matters

Strategically notable because Pathos is positioning it as an AI-sourced clinical oncology acquisition. The read-through is that AI-native developers are starting to use proprietary asset-screening platforms not just to design programs internally, but to identify and buy clinical-stage assets with differentiated early data.

Why it matters

UCB is doubling down on immunology with a platform-style acquisition built around T-cell engagers for autoimmune disease. The deal reinforces the broader sector push toward immune reset approaches, where oncology-derived modalities are being repurposed for chronic autoimmune indications with potentially deeper and more durable efficacy.

Stage / lead assets
NEXLETOL and NEXLIZET, approved oral non-statin LDL-C lowering therapies
Why it matters

A public-to-private commercial-stage cardiovascular takeout rather than a classic discovery-platform deal. The read-through is that financial sponsors are prepared to underwrite commercial execution where public markets have struggled to price specialty-pharma assets — especially with an approved product base and clearer operating levers outside the public-company spotlight.

EKTERLY / sebetralstat, an oral on-demand treatment for HAE attacks
Why it matters

Chiesi is buying a near-commercial rare-disease asset that could change the HAE treatment paradigm by moving on-demand therapy toward an oral option. Strategics will pay meaningful premiums for late-stage / launch-ready rare-disease assets where convenience can drive differentiation and the buyer can plug the product into an existing rare-disease infrastructure.

Why it matters

Teva is adding an NDA-ready neuroscience asset that fits its pivot toward branded growth and specialty neurology. Buyers are willing to pay for late-stage CNS assets when the regulatory path is close and the product can slot into an existing commercial footprint — even in indications that historically have seen limited therapeutic innovation.

Biopharma royalties / royalty aggregation
Stage / lead assets
Diversified portfolio of biopharma royalty and milestone interests
Why it matters

Shows consolidation in royalty aggregation. The read-through is that royalty portfolios remain attractive strategic assets when acquirers can combine diversified cash-flow streams, lower public-company costs, and create scale in non-dilutive biopharma financing infrastructure.

Why it matters

Lilly is again using private-company M&A to deepen oncology / hematology exposure, this time around a potentially differentiated JAK2 profile in MPNs. Strategic appetite remains strong for targeted hematology assets when the mechanism is validated but the product profile could still improve on tolerability, selectivity, or depth of response.

Why it matters

The largest disclosed 2026 biopharma M&A deal on the tracker — more about commercial scale than single-asset R&D risk. Sun Pharma is using M&A to add a global branded portfolio, women's-health infrastructure, and biosimilar exposure, reinforcing that strategics will pay up for durable commercial platforms when growth, geographic reach, and portfolio breadth are immediately accretive.

Why it matters

Gilead is expanding beyond cell therapy and immunology into a deeper ADC capability set — buying not just a clinical ovarian-cancer asset but differentiated linker-payload and conjugation technology. Buyers are still willing to pay heavily for clinically anchored oncology platforms when they can strengthen a broader franchise rather than add a single isolated asset.

Methodology

This tracker focuses on company-level control transactions announced or first publicly disclosed in 2026 across biotech/biopharma, including selected royalty and biopharma-infrastructure transactions where the target is a public biopharma-linked company. Headline values are shown on the basis most prominently disclosed (enterprise value, equity value, upfront cash plus milestones, or per-share cash plus CVR structure). Rumour-only situations are excluded and tracked separately.
