Curium Agrees to Buy Lantheus in Deal Valued at Up to $8 Billion

The all-cash offer includes contingent payments and will be financed with debt and equity as the companies prepare for regulatory review and integration.

Overview

  • The agreement announced Monday gives Lantheus shareholders $102.50 per share in cash plus non-transferable contingent value rights that could add up to $12 by 2030, bringing total possible consideration to $114.50 per share.
  • The transaction will take Nasdaq-listed Lantheus private and is expected to close in the first half of 2027 with funding from a mix of debt and equity provided by Curium and its backer CapVest Partners.
  • Analysts described the $102.50 upfront as fair but not generous and noted the premium over recent trading; Lantheus stock rose after the announcement.
  • Market watchers warned the deal may face heightened regulatory scrutiny because both firms are major providers in diagnostic radiopharmaceuticals, a fast-growing area used in PET imaging and targeted therapies.
  • Lantheus’s lead product Pylarify and Curium’s global manufacturing and theranostics capabilities are central to the rationale for the tie-up, which industry deals suggest will further consolidate the radiopharmaceuticals market and could affect patient access and competition.
