Insights

Corporate Governance Specialist

Insider sale details clarified with an amendment; ownership remains substantial.

The amendment documents an officer-level sale of 248,168 shares at a weighted average of $15.78, reducing direct holdings to 2,261,157 shares. Including the Power of Attorney formalizes the representative signature and ensures filing completeness.

Such filings routinely disclose liquidity events by insiders; monitor any patterned sales in subsequent filings over the next 3–6 months to assess whether this was isolated or part of a broader disposition schedule.

Equity Transactions Analyst

Sale magnitude is measurable but not disclosure of trading program; price range and weighted average are provided.

The sale was executed in multiple transactions with prices between $15.69 and $15.885, and the filer offers to supply detailed per-trade quantities on request. The weighted-average price $15.78 gives a concise view of proceeds but the total cash amount is not explicitly stated.

Investors seeking transaction-level clarity can request the per-trade breakdown; absent that, treat this as a confirmed, single-day disposal reported under Section 16 with clear post-sale ownership figures as of 09/10/2025.
