Mergers & Acquisitions

M&A Summary Table

Genmab Acquires Merus for $8.0 Billion

Transaction Date: September 29, 2025

Acquiring Company: Genmab A/S (Copenhagen, Denmark; NASDAQ: GMAB)
Target Company: Merus N.V. (Utrecht, Netherlands; NASDAQ: MRUS)

Transaction Structure and Valuation: The all-cash tender offer values Merus at $97.00 per share, representing a 41% premium over the September 26 closing price of $68.89 and a 44% premium over the 30-day volume-weighted average price of $67.42. The total enterprise value reaches $8.0 billion, with Genmab financing the acquisition through cash on hand plus approximately $5.5 billion in non-convertible debt from Morgan Stanley Senior Funding. The company targets a leverage ratio below 3x within two years of closing, with the transaction requiring minimum 80% shareholder acceptance (reducible to 75%).

Crown Jewel Asset - Petosemtamab: The acquisition centers on petosemtamab, a bispecific antibody targeting EGFRxLGR5 for head and neck squamous cell carcinoma (HNSCC). This asset holds two FDA Breakthrough Therapy Designations for both first-line and second-line-plus treatment settings. Phase 2 results presented at ASCO 2025 demonstrated compelling efficacy: 79% overall survival at 12 months, 63% confirmed response rate (27 of 43 patients), and median progression-free survival of 9 months when combined with Keytruda. Two Phase 3 trials are currently ongoing (NCT06525220 and NCT06496178) with topline interim data expected in 2026 and anticipated launch in 2027.

Financial Projections and Strategic Rationale: Analysts project petosemtamab will generate over $1 billion in annual sales by 2029, with multi-billion-dollar peak sales potential (estimated $3-4 billion in HNSCC alone). The transaction should become EBITDA accretive by end of 2029. This represents the third-largest biotech M&A of 2025, accelerating Genmab's transition to a wholly-owned business model while adding a late-stage best-in-class asset that complements its existing portfolio (Darzalex, Tivdak, Epkinly). The transaction is expected to close in early Q1 2026.

Halozyme Acquires Elektrofi for Up to $900 Million

Transaction Date: October 1, 2025

Acquiring Company: Halozyme Therapeutics, Inc. (San Diego, CA; NASDAQ: HALO)
Target Company: Elektrofi, Inc. (privately held, US-based)

Deal Economics: Halozyme will pay $750 million upfront with potential milestone payments of up to $150 million (structured as three $50 million payments tied to product regulatory approvals), bringing total potential value to $900 million. The company is financing the acquisition through cash reserves and its credit facility, with post-close leverage expected at approximately 2X net debt-to-EBITDA.

Revolutionary Hypercon™ Technology: Elektrofi's proprietary Hypercon™ platform represents a breakthrough in biologic delivery, enabling drug concentrations of 400-500 mg/mL (4-5 times standard concentrations). This microparticle technology enables low-volume at-home subcutaneous delivery with long-term IP protection extending into the 2040s, perfectly complementing Halozyme's existing Enhanze technology for rapid, high-volume delivery.

Existing Partnership Portfolio: Elektrofi brings valuable partnerships including Eli Lilly (October 2023: $20 million upfront plus over $150 million per target for 3 targets, up to $470 million total), Johnson & Johnson/Janssen (January 2024: $18 million upfront for 5 programs with over $155 million per target in milestones, approximately $800 million total), and argenx (April 2021: subcutaneous formulation development).

Commercial Timeline and Advisors: Two partner products are expected to enter clinical development by end of 2026, with royalty revenue contribution anticipated as early as 2030. The company could receive up to $275 million in development and commercial milestones from the initial two products. The transaction, expected to close in Q4 2025, was advised by BofA Securities (Halozyme) and Centerview Partners (Elektrofi) as financial advisors, with Weil, Gotshal & Manges (Halozyme) and Morgan, Lewis & Bockius (Elektrofi) serving as legal counsel.

Market Context & Emerging Trends

M&A Market Dynamics

The Genmab-Merus transaction represents the third-largest biotech M&A of 2025, following J&J's $14.6 billion acquisition of Intra-Cellular and Sanofi's up to $9.5 billion acquisition of Blueprint. Strategic buyers continue focusing on de-risked, late-stage assets with near-term approval potential. Smaller tactical acquisitions (Boston Scientific, Halozyme) demonstrate ongoing appetite for technology platform deals, while private biotech M&A activity accelerates.

Venture Capital Trends

"Megarounds" of $100 million or more dominated the week, with 2 of 4 venture deals exceeding this threshold. Investors strongly favor experienced teams with de-risked assets. Despite Q2 2025 seeing biotech VC funding fall to $4.8 billion (lowest in 3 years) and first financings dropping to $900 million (5-quarter low), quality companies continue attracting substantial capital. Corporate venture firms including Pfizer Ventures, Amgen Ventures, and Sanofi Ventures remain actively engaged.

Public Markets Performance

Ocular's $475 million offering demonstrates sustained appetite for late-stage ophthalmology assets. Public biotech fundraising outperformed private markets in September 2025 for the third time this year. However, the IPO market remains largely frozen with only 3 biotech IPOs in Q2 2024. The biotech sector continues underperforming broader markets, up just 1.13% in 2024 versus the S&P 500's 18.5% gain.

Alternative Financing Mechanisms

Royalty financing provides a critical "lifeline" for biotechs with $5.42 billion annualized in H1 2025. Companies increasingly seek non-dilutive alternatives including licensing deals and royalty monetizations. Rising interest rates near 20-year highs continue constraining venture lending options. Big Pharma maintains strong negotiating positions with deeper cash reserves.

Therapeutic Innovation Focus

Oncology remains the hottest therapeutic area with 6 deals this week. Hematology and bleeding disorders attract significant capital with innovative approaches. Brain health and neurology emerge as growth areas with 2 licensing deals and 1 venture investment. Drug delivery platforms gain traction as enabling technologies. CNS drug delivery addressing the blood-brain barrier represents a key innovation frontier.

Deal Timing Analysis

The week of September 29-October 5 represented relatively normal deal flow, falling between Q3 end and Q4 start (typical transition period). Major conference activity (J.P. Morgan Healthcare Conference in January, BIO International Convention in June) drives peak deal announcements. This period showed steady but not exceptional activity.
