Pay and ownership Proxy statement filed 23 April 2026

Chief executive’s pay

Year Total pay Actually paid $100 invested
2025 1.88m 4.43m 159.75
2024 1.19m 1.33m 44.07
2023 1.75m 801.28k 44.92

Ownership

Directors and executive officers, together 1.30%
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
