Business Context and Reporting Period
This Form 6-K filing by GSK plc, dated April 18, 2023, announces a definitive agreement to acquire BELLUS Health Inc., a Canada-based late-stage biopharmaceutical company. The transaction is designed to strengthen GSK's specialty medicines and respiratory pipeline by adding camlipixant, a highly selective P2X3 antagonist in Phase III development for refractory chronic cough (RCC).
Key Financial Metrics and Transaction Details
- Acquisition Price: US$14.75 per share in cash.
- Total Equity Value: Approximately US$2.0 billion (approx. £1.6 billion).
- Premium: Represents a ~103% premium to BELLUS' closing stock price on April 17, 2023, and a ~101% premium to the 30-day volume-weighted average price.

- EPS Impact: Expected to be accretive to adjusted earnings per share (EPS) from 2027, the anticipated first full year of camlipixant sales.
- Closing Timeline: Expected in the third quarter of 2023 or earlier, subject to customary conditions.
Material Changes and Strategic Rationale
The acquisition marks a strategic expansion into the treatment of RCC, a condition affecting an estimated 10 million patients globally with no currently approved medicines in the US or EU. Camlipixant is positioned as a potential best-in-class treatment due to its high selectivity, which clinical data suggests may result in a lower incidence of dysgeusia (taste disturbance) compared to broader P2X2/3 antagonists. The deal leverages GSK's existing expertise in respiratory therapies, R&D, and commercialization.
Guidance, Outlook, and Risks

- Risks and Contingencies: The transaction is subject to regulatory approvals, court approval, and shareholder approval (requiring at least 66.67% of votes cast).
