Seven questions, 60-second thesis frame.

What changed, and when

Novo Nordisk disclosed on 30 Oct 2025 that it submitted an unsolicited proposal to acquire Metsera, including CVRs tied to clinical and regulatory milestones. (Company announcement) Independent reports confirm the $56.50 per share cash headline price and intent to top Pfizer’s signed deal. (Reuters)

60-second thesis frame

Novo is trying to pre-empt a future obesity competitor by outbidding Pfizer’s 22 Sept 2025 definitive agreement for Metsera, which carried $47.50 cash per share plus CVRs up to $22.50. (Pfizer press release, Financial Times) Novo’s proposal offers $56.50 per share in cash and CVRs up to $21.25, with a two-step structure issuing non-voting preferred to 50% at signing, then CVRs at closing. (Company announcement, Metsera PR detailing “Superior Company Proposal” and 4-business-day match right) Metsera’s draw is MET-097i, an ultra-long-acting, fully biased GLP-1 RA that showed up to 14.1% placebo-adjusted weight loss at 28 weeks in Phase 2b, with a tolerability profile Metsera positions as favorable, and a path to Phase 3 starting late 2025. (GlobeNewswire topline, Metsera 8-K) If Novo succeeds, it deepens its obesity portfolio around Wegovy, now with a CV risk reduction label in the US, and potentially adds a monthly-dosing contender. (FDA Wegovy label s011)

The seven diligence questions

Clinical

• How robust are MET-097i’s Phase 2b effects across BMI bands and subgroups, and do monthly regimens maintain efficacy beyond 28 weeks without safety drift, especially GI events? (GlobeNewswire topline)
• Are the mechanism claims around “fully biased” GLP-1 translating into clinically meaningful tolerability advantages versus weekly semaglutide or tirzepatide in like-for-like populations? (GlobeNewswire topline)

Payer or Access

• If MET-097i targets monthly dosing, does that improve adherence and payer economics versus weekly GLP-1s, and would CV-outcome evidence be required for premium positioning in the US and EU? (FDA CV label expansion for Wegovy)
• How would codes, prior auth criteria, and step edits evolve if monthly GLP-1s enter, given current GLP-1 utilization controls and evolving shortages guidance? (FDA GLP-1 compounding/shortage notice)

Ops or Adoption

• Can Novo scale monthly-dose supply chains and devices without constraining Wegovy growth in 2026–2027, and what are the fill-finish implications?

Competitive

• How does a monthly GLP-1 stack up against Lilly’s Zepbound trajectory and future orals or duals, and could combo strategies outflank mono-agonists by 2028–2030? (FDA Zepbound approval)

Team or Cap table

• What restrictions sit in Pfizer’s merger agreement regarding superior proposals, voting agreements, fees, and timing, and how do they shape the board’s freedom to pivot? (Metsera 8-K summary, Merger Agreement, Sec. 5.02(e) 4-business-day match right)

Red flags

• Deal certainty, Pfizer signed first. A $190 million termination fee applies if Metsera exits to a superior proposal, and Pfizer holds a four-business-day matching right. (Metsera 8-K, Merger Agreement 5.02(e))
• Antitrust risk, incumbent acquiring a pipeline rival in obesity, triggering HSR and likely EC review. (FTC HSR overview, EU merger procedures)
• Clinical execution, Phase 3 generalizability and monthly regimen durability must replicate 2b magnitude and tolerability. (GlobeNewswire topline)

Next catalyst

Four-business-day Pfizer “match” window runs through roughly Wed 5 Nov 2025, subject to the agreement’s notice mechanics, after Metsera declared Novo’s bid a “Superior Company Proposal.” (Metsera PR, Merger Agreement 5.02(e))

FAQ

• What exactly changed by Novo Nordisk’s “unsolicited proposal” on 30 Oct 2025, and why does it matter for obesity therapeutics?
  Novo offered $56.50 per share cash plus CVRs up to $21.25, aiming to top Pfizer’s signed deal, which could shift the ownership of a potential monthly GLP-1 entrant. (Company announcement, Reuters)
• What is the regulatory path after “unsolicited proposal,” and what are the next formal steps in the US and EU?
  Any definitive deal would require HSR filing and waiting period in the US, plus EU merger control if thresholds are met. (FTC HSR overview, EU merger procedures)
• Which endpoints in Metsera’s program drove the result cited in “positive Phase 2b results” on 29 Sept 2025, and how meaningful was the effect size?
  VESPER-1 showed up to 14.1% placebo-adjusted weight loss at 28 weeks with low discontinuation, supporting late-2025 Phase 3 initiation plans. (GlobeNewswire topline, Metsera 8-K)
• What safety issues matter post-“positive Phase 2b results,” and do they change real-world use?
  Early topline flagged a relatively modest GI AE profile at evaluated doses, but Phase 3 must confirm tolerability at monthly dosing. (GlobeNewswire topline)
• How will major US payers treat access after “unsolicited proposal,” including prior auth and codes, and are analogues informative?
  CV-risk labeling helped Wegovy’s medical-necessity positioning, but GLP-1 utilization controls persist, so monthly dosing must show adherence value. (FDA CV label expansion for Wegovy, FDA compounding/shortage policy note)
