Insights

Equity Compensation & Governance Analyst

Routine stock grant increases executive equity stake through time‑vested RSUs.

Olivier Blachier, SVP and Chief Strategy Officer, received 15,278 restricted stock units of Entegris common stock as an equity award under the 2020 Stock Plan. The grant is compensation for services as an employee, with no cash paid by the insider.

The units vest in two equal installments on February 19, 2027 and February 19, 2028, tying value realization to continued service. After this grant and earlier employee stock purchase activity, he directly beneficially owns 29,533.95 shares. This appears to be a standard executive compensation transaction rather than a market signal.
