Insights

Corporate Governance Analyst

Insider sales were executed under a pre-established 10b5-1 plan, and a family trust retains large indirect holdings.

The filing confirms the sales on 10/01/2025 were made pursuant to a Rule 10b5-1 plan adopted 12/31/2024, which indicates the transactions were pre-planned and compliant with insider-trading rules. The disclosure of 1,098,512 shares held by the Phillips Family Trust shows continued significant indirect ownership. The transfer of 18,904 shares from the trust to Mr. Phillips increases his direct stake and is explicitly reported in the filing.

Equity Markets Specialist

The CFO sold 18,904 shares across two reported dispositions at prices between $37.13 and $38.76.

The reported weighted-average prices are $37.7442 and $38.2519 for the two sale lines totaling 18,904 shares. These sales modestly reduce direct holdings reported on the form (shown as 686,495 and 683,425 on the respective lines). Because the trades were under a 10b5-1 plan, they reflect scheduled liquidity rather than ad hoc dispositions according to the filing.
