Corrigan Catherine 4

What Happened
Catherine Corrigan, President & CEO and a director of Exponent (EXPO), exercised stock options and sold a portion of the resulting shares on March 16, 2026 and April 15, 2026. She exercised a total of 11,211 option shares (3,226 + 2,380 on 3/16; 3,225 + 2,380 on 4/15) at exercise prices of $25.41 (3,226/3,225 shares) and $29.05 (2,380 shares each date), incurring aggregate exercise costs of about $302,166. On the same dates she sold a total of 7,821 shares (3,912 on 3/16 and 3,909 on 4/15) in open-market transactions at prices of $67.49 and $67.70, generating combined proceeds of approximately $528,639. The sequence — option exercise followed by sales on the same days — is consistent with a cashless exercise where some exercised shares are immediately sold to cover costs/taxes.

Context

• These filings show option exercises (derivative transactions) followed by open-market sales of shares — commonly a cashless exercise pattern used to cover exercise costs and taxes. Exercises are informative (management converting options into shares), while routine sales after exercise do not necessarily signal a change in view of the company.
• The filing does not provide additional plans (e.g., a 10b5‑1 plan) or indicate gift/tax‑withholding codes beyond the standard exercise and sale entries.
