DEEP FISSION CFO William Schmitz Receives 15,000-Share Award

What Happened
William Mark Schmitz, Chief Financial Officer of DEEP FISSION, INC., was awarded 15,000 derivative shares (an equity award, likely stock options) on 2026-02-18. The filing reports an acquisition at $0.00 per share (total reported value $0), meaning no cash changed hands at grant. This is a compensation award rather than a market purchase or sale.

Key Details

  • Transaction date: 2026-02-18; Filing date (accession): 2026-02-23.
  • Reported price: $0.00 per share; reported total value: $0.
  • Shares/derivatives granted: 15,000 (derivative securities).
  • Shares owned after transaction: Not specified in the summary provided.
  • Vesting: Footnote indicates 25% vests at the first vesting date, then 1/36 of the total vests each month thereafter until fully vested (typical 4‑year schedule). The specific first vesting date was not shown here.
  • Timeliness: Filing occurred 5 calendar days (3 business days) after the transaction; Form 4s are generally due within 2 business days, so this appears later than the usual deadline.

Context
This award is a form of equity compensation (likely options) that gives the holder future rights to acquire stock subject to vesting and any exercise price. It is not an immediate purchase or sale and does not by itself signal intent to buy or sell in the open market. The reported $0 value reflects no cash paid at grant; any future value depends on the company’s share price and the award’s exercise terms.
