Insights

Financial Analyst

TL;DR: Insider executed repeated stock sales totaling 276,319 shares; a proposed further sale of 21,376 shares is disclosed.

The data show substantial insider disposals over a short window (09/10/2025–09/25/2025) by James A. Burke, totaling 276,319 shares with individual gross proceeds reported per trade. The Form 144 notifies a proposed sale of an additional 21,376 shares valued at $4.3 million using Fidelity as the broker. For a company with 338,820,324 shares outstanding, the proposed sale represents a very small fraction of total equity, and the filing indicates the shares were acquired via an option grant (04/09/2018) with settlement noted on 09/26/2025.

Corporate Governance Expert

TL;DR: Pattern of scheduled insider sales is disclosed; representation asserts no undisclosed material information.

The Form 144 and accompanying sales history indicate compliance with disclosure requirements for proposed officer/director/affiliate sales. The signer represents there is no known undisclosed material adverse information, and a trading/option exercise settlement is documented. The frequency of sales over consecutive days suggests routine liquidation following option exercise rather than a single large ad hoc disposition.
