Insights

Corporate Insider / Securities Compliance Analyst

TL;DR: Insider sales were routine, executed under an established 10b5-1 plan; sizes are small relative to typical executive holdings.

The reported sales on 10/06/2025 were carried out under a Rule 10b5-1 trading plan adopted on 08/21/2024, which is a pre‑arranged framework allowing scheduled transactions. The filing discloses weighted average prices and the specific per‑share ranges: $128.30–$129.26 and $129.40–$129.63, and reports post‑transaction beneficial ownership levels in the filing.

The primary dependency is the plan's preauthorization; no new material disclosures (such as unusual timing or open‑market block sales) are stated. Investors might note timing relative to public disclosures or market moves; any further detail on per‑price share counts is available only upon SEC staff request. Expect no immediate governance implications unless additional transactions are reported.
