Insights

Large, disclosed insider sales by a 10% beneficial group; filing shows standard disclaimers.

The filings show the Southpoint group executed multiple open-market sales totaling 67,114 shares over three days ending on 10/09/2025

These sales were reported under the investment-manager/general-partner structure and include the customary disclaimer of beneficial ownership except for pecuniary interest. Monitor subsequent Form 4s for further reductions or any director-level sales that change board alignment within the next 30–90 days.

Sales occurred at prices near $9.35–$9.59, likely modest market impact given multi-day execution.

Transaction notes state each tranche was executed in multiple trades with reported weighted-average prices of $9.5871, $9.4732, and $9.3461

If these represent liquidation of fund holdings, watch volume and share-price movements in the days around 10/07/2025–10/09/2025 and any further disclosures of sales or transfers within the next quarter.
