GSK Completes $950 Million Acquisition of 35Pharma to Enhance Pipeline
- Acquisition Completed: On April 15, 2026, GSK plc announced the completion of its $950 million acquisition of Canadian clinical-stage biopharmaceutical firm 35Pharma Inc., granting GSK full control over 35Pharma and its pipeline, strategically enhancing its market position in pulmonary hypertension treatment.
