Deep Isolation Nuclear (NONE) CFO Nelson Joseph Eugene Receives RSUs & Options

What Happened

Nelson Joseph Eugene, Chief Financial Officer of Deep Isolation Nuclear, was granted two equity awards on 2026-05-27: 100,000 restricted stock units (RSUs) and 40,000 stock options. Both awards were reported as acquisitions (code A) at $0.00 per share (typical for compensation grants), so no cash was exchanged in these transactions.

Key Details

Transaction date: 2026-05-27; Filing date: 2026-05-29 (timely filing).

Options (derivative): 40,000 option shares, $0.00 per share/grant (footnote F2).
Shares owned after the transaction: not specified in the provided filing excerpt.
Footnotes:
- F1: RSUs represent the right to receive one share per RSU upon vesting; vest 25% annually over four years starting Feb 24, 2027, subject to continued service.
- F2: Options vest over four years beginning Feb 24, 2027 (1/4 vesting on that date, then 1/48 monthly thereafter), subject to continued service.
No exercise or sale noted — these are compensation awards, not market purchases or disposals.

Context

RSUs are contingent rights to receive shares when they vest; they do not create immediate share sales or cash proceeds. Stock options are a derivative grant giving the right to buy shares in the future if and when exercised; these options have a multi-year vesting schedule and were not exercised in this filing.
Such grants are common senior-executive compensation. They are informative about management compensation and potential future dilution but do not necessarily indicate an immediate bullish or bearish signal.
