Insights

Securities Analyst

TL;DR Insider plans to sell 105,000 restricted shares via Morgan Stanley, representing a small fraction of outstanding stock.

The filing documents a Rule 144 proposed sale of 105,000 common shares valued at about $1.14 million, executed through Morgan Stanley on NASDAQ. The securities were received as restricted stock across multiple grants from 2022 to 2025, with the largest single grant on 05/21/2025 for 77,363 shares. No sales in the prior three months were reported. From a market-impact perspective, 105,000 shares equal roughly 0.085% of the reported 123,160,881 shares outstanding, which is unlikely to meaningfully affect supply-demand dynamics. The disclosure is procedural and compliant with Rule 144 requirements.

Corporate Governance Expert

TL;DR The filing is a routine insider sale notice showing restricted-stock vesting and planned disposition; no governance red flags are apparent.

The report lists multiple restricted-stock acquisitions from the issuer between 2022 and 2025 and a planned aggregated sale of those vested shares. The signer affirms absence of undisclosed material information and that no sales occurred in the prior three months. Documentation of acquisition dates and broker details aligns with standard Rule 144 compliance. There is no indication of unusual timing, clustered insider activity, or departures; the notice reads as a standard liquidity event by an insider or related person.
