Insights

Securities Analyst

TL;DR Routine insider notice of a proposed sale: moderate size, no recent sales, not necessarily material to company fundamentals.

The Form 144 notifies the SEC of a proposed sale by an insider or affiliate totaling 93,276 shares valued at about $2.14 million. Sales will be brokered by Stifel on Nasdaq on 09/19/2025. The holdings were acquired over 2013–2017 and paid in cash to the issuer, indicating long-standing ownership rather than recent option exercises. Absence of sales in the past three months reduces concerns about an accelerated disposition program. This filing is transactional and does not disclose operational or financial performance changes.

Corporate Governance Expert

TL;DR Compliance disclosure appears complete for a Rule 144 sale; no red flags from the filing alone.

The filer attests they are unaware of undisclosed material adverse information and provides acquisition dates and payment nature for the shares. The form includes broker and execution date details, meeting standard Rule 144 notice requirements. There is no indication of a 10b5-1 plan adoption date, and no prior three-month sales are reported. From a governance perspective, the document satisfies routine transparency expectations for insider dispositions.
