Pay and ownership Proxy statement filed 27 April 2026

Chief executive’s pay

Year Total pay Actually paid $100 invested
2025 4.70m 4.29m 74.43
2024 3.93m 6.05m 71.70
2023 3.68m (1.22m) 50.43

Ownership

Directors and executive officers, together 11.80%
Perceptive Advisors LLC 6.90%
Todd C. Brady, M.D., Ph.D. 6.80%
Knoll Capital Management, LLC 6.00%
BlackRock, Inc. 5.70%
Total pay is as the Summary Compensation Table states it; actually paid revalues the year’s share awards at its end, as the SEC’s pay-versus-performance rule asks. $100 invested is what $100 in the company’s shares at the start of the earliest year shown was worth at each year’s end. Ownership is the proxy’s own table: the directors and officers as a group, and every holder of 5% or more. Read the proxy statement
