Amprius (AMPX) CEO Thomas Stepien Receives 150,000-Share Award

What Happened

  • Thomas M. Stepien, CEO of Amprius Technologies (AMPX), was granted 150,000 restricted stock units (RSUs) on March 4, 2026. The award is reported as an "A" (award/grant) transaction at $0.00 per share (no cash exchanged at grant).
  • This is a compensation award rather than a purchase or sale; RSUs typically vest over time and do not represent immediately tradable shares.

Key Details

  • Transaction date: 2026-03-04; Form 4 filed: 2026-03-06 (timely filing).
  • Grant amount and price: 150,000 RSUs granted at $0.00.
  • Vesting: Per footnote F1, 1/16th of the award vests on May 20, 2026 and then quarterly on Aug 20, Nov 20, Feb 20 and May 20 thereafter, with full vesting on Feb 20, 2030, subject to continued service.
  • Additional holdings: Footnote F2 references 750,000 RSUs that represent contingent rights to receive shares (included in the filing); the filing excerpt provided does not state total shares beneficially owned after this grant.
  • Transaction code: A = Award/Grant (not a market buy/sell). No 10b5-1 or tax-withholding details disclosed in the excerpt.

Context

  • RSU grants are typical executive compensation and do not indicate an immediate market purchase or sale. Vesting schedule means the CEO will only receive actual shares over time if service conditions are met.
  • Because the grant was reported promptly (filed two days after the transaction), there is no late-filing concern indicated in the provided information.
