Insights

Corporate Governance Expert

TL;DR: Routine insider disposition disclosed; senior executive retains substantial direct and indirect ownership.

The Form 4 documents a single reported disposition (Code G) of 40,000 shares by Wendell P. Weeks on 09/15/2025. Code G filings commonly indicate a transaction under a written plan or similar mechanism; the form itself includes no commentary beyond the transaction and ownership tallies. Post-transaction direct ownership of 772,101 shares suggests the CEO maintains a significant equity stake. Indirect holdings through spouse and the issuer's 401(k) plan are disclosed and the reporting person expressly disclaims beneficial ownership of spouse-held shares. From a governance perspective, the company received timely disclosure and the filing is complete for the items reported.
