No derivative transactions reported, only non-derivative common stock sales

Negative

Total insider dispositions of 50,000 shares on September 18-19, 2025, which represents a material transfer of holdings by the reporting person

Insights

TL;DR: Reporting person sold 50,000 shares under two Rule 10b5-1 plans; remaining direct ownership stays above 2.3 million shares.

The filings show four non-derivative sale transactions on September 18-19, 2025, executed pursuant to two documented 10b5-1 plans. Reported prices are provided as weighted averages with disclosed intra-range trade prices. Total shares sold equal 50,000, and direct beneficial ownership after the sales is 2,320,852 shares, with an additional 15,000 shares held indirectly by a spouse. No options or other derivative activity is reported. The disclosure is clear and follows Section 16 reporting conventions.

TL;DR: Sales were processed via pre-set trading plans, reducing potential signaling but still reflect material insider liquidity.

The Form 4 documents voluntary dispositions executed under Rule 10b5-1 plans adopted earlier in 2025, which typically provides an affirmative defense against claims of trading on material nonpublic information. The report includes weighted-average prices and ranges for each grouped sale, and the signature by an attorney-in-fact is present. The disclosure is procedurally complete: multiple lines for each class were reported and indirect ownership through a spouse is identified.
