Insights

Corporate Governance / Insider Trading Expert

TL;DR: Significant open-market sales by an affiliated investor reduced holdings; disclosure is explicit with weighted-average pricing.

The filings report four separate sale events on 10/08/2025 and 10/09/2025 totaling 124,146 shares sold at weighted-average prices between $31.9181 and $34.3391. The reporting structure shows sales executed by Reprogrammed Interchange LLC and by an individual reporting person, with beneficial ownership attributed to Reprogrammed at 1,374,775 shares after the transactions.

Risk dependencies include market impact and timing: these are open-market dispositions (transaction code S), and the filings disclose only weighted-average prices while offering to provide per-trade detail on request. Monitor subsequent Forms 4 for additional disposals or changes in beneficial ownership in the near term (weeks to months) to assess ongoing insider positioning.
