Insights

Securities Analyst

TL;DR: Insider proposes to sell 34,?170 common shares via two brokers on 09/16/2025, mostly from RSU vestings and some open-market purchases.

The Form 144 lists proposed dispositions of 11,530 shares through Morgan Stanley and 23,640 shares through Merrill EDGE, both on NASDAQ, with aggregate market values supplied per broker line. Acquisition records show most shares originate from multiple RSU vesting events (2024–2025) and an open-market purchase in March 2023. No prior sales in the past three months are reported, and the filer attests there is no nonpublic material adverse information. For investors, this is a routine report of an insider selling vested shares rather than a corporate disclosure of operational or financial change.

Corporate Governance Expert

TL;DR: Filing documents routine insider disposition of vested shares with required attestation; no red flags in disclosures provided.

The notice includes required compliance language and lists the nature of acquisitions (RSU vestings and an open-market purchase). The schedule indicates proper aggregation of shares and identifies brokers and sale dates. Absence of reported sales in the prior three months simplifies assessment of recent insider trading activity. The representation regarding material adverse information is present, as required. The document appears procedural and compliant based on the information shown.
