What the filing says
Sotera Health appointed Alton E. Shader as Chief Executive Officer, effective May 26, 2026, with annual base salary of $1,000,000, an AIP target of 110% of base salary ($1,100,000), a sign-on equity grant of $6,000,000 in RSUs, an initial equity award of $6,500,000 (50% RSUs, 50% PSUs), and initial SAU award of $1,625,000. Michael B. Petras, Jr., the prior CEO, transitioned to Executive Chairman with reduced base salary from $1,000,000+ to $900,000 annually and equity target reduced from $6,500,000 to $5,000,000 beginning 2027. Total first-year compensation to Shader is approximately $14,725,000; Petras's annual run-rate compensation decreased by approximately $1,600,000+ in equity value plus $100,000 salary reduction.
Why this rating
CEO succession is meaningful governance event; total pay packages material relative to $1.7B market cap (~0.9% for Shader, ~0.1% annual equity reduction for Petras). Leadership transition risk balanced against planned continuity via Executive Chairman role.
