No shares were sold or otherwise disposed of, so the director’s beneficial ownership rose while the company incurred no immediate cash expense.
ClearSign Technologies Corp. (CLIR) – Form 4 filing dated 07/03/2025
Non-executive director Catharine de Lacy received 32,175 Restricted Stock Units (RSUs) on 07/01/2025 under the company’s 2021 Equity Incentive Plan as quarterly board compensation. Each RSU entitles the holder to one share of common stock (or cash equivalent) at vesting. Following the award, the director now beneficially owns 218,957 derivative securities tied to CLIR common stock and retains direct ownership (no indirect ownership reported).
The RSUs vest upon the earliest of: (1) a change in control, (2) the director’s disability, (3) death, or (4) separation from service. No open-market purchase or sale occurred; the transaction code “A” denotes an award.
For investors, this filing signals routine equity-based compensation designed to align director interests with shareholder value. It does not reflect cash outflows by the company nor insider buying pressure in the open market.
ClearSign Technologies Corp. (CLIR) Form 4 filing shows that non-executive director Judith S. Schrecker received 46,296 Restricted Stock Units (RSUs) on 01 July 2025 as quarterly board compensation under the 2021 Equity Incentive Plan.
The RSUs carry an exercise price of $0.00 and will vest upon the earliest of: (1) a Change in Control; (2) the director’s disability; (3) death; or (4) separation from service. Each RSU converts into one share of common stock or its cash equivalent.
Following the grant, Schrecker’s total derivative holdings increased to 431,957 RSUs. No common shares were sold or otherwise disposed of, and the transaction was filed individually by the reporting person.
Because the award represents routine board compensation without immediate vesting or open-market activity, the market impact is expected to be limited, though it modestly enhances insider equity alignment.
