Insights

Securities Compliance Analyst

Form 144 lists Rule 144 sale notices and recent shareholder disposals.

These entries document a reportable Section 16-type sale pathway: an exercise of stock options producing 9,200 shares dated 04/21/2026, and multiple cash dispositions by the same shareholder earlier in the year. The filing is procedural, notifying the market of planned or completed resale activity under resale rules.

Cash‑flow treatment is apparent in the claimed sale proceeds per line; timing and transfer mechanics follow Rule 144 notice practice. Subsequent SEC disclosures or broker reports would confirm settlement details.
