Insights

Securities Analyst

TL;DR: Insider plans to sell 2,750 vested RSU shares via UBS; prior recent sales of identical amounts were disclosed.

The filing documents a routine Rule 144 sale of 2,750 common shares through UBS Financial Services with an indicated sale date of 08/15/2025. Acquisition details show these shares were vested RSUs acquired and paid for on 05/19/2022. The filer also reported two recent sales in June and July 2025, each of 2,750 shares, with gross proceeds disclosed. From a market-impact perspective, the absolute size is small relative to the reported outstanding shares, and the disclosure follows required Rule 144 reporting conventions. The absence of completed entries in the remarks/signature area should be confirmed as an administrative omission.

Corporate Compliance Officer

TL;DR: Filing appears procedurally standard but includes missing entries in the remarks/signature fields that warrant attention.

The Form 144 provides the necessary transaction tables: issuer, broker, class, amount, market value, acquisition source
