Pay and ownership Proxy statement filed 30 March 2026

Chief executive’s pay

Year Total pay Actually paid $100 invested
2025 2.50m 2.20m (12.00)
2024 2.76m 3.02m 79.00
2023 2.36m 2.65m (67.00)

Ownership

Directors and executive officers, together 9.80%
Steven C. Quay, M.D., Ph.D. 8.30%
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
