Weiser Charles Maurice 4

What Happened

• Weiser Charles Maurice, Chief Financial Officer of 374Water Inc. (SCWO), was granted two equity awards on July 1, 2026: a stock option for 150,000 shares (derivative) and 125,000 restricted stock units (RSUs). Both awards were reported as acquisitions at $0.00 (grant). The option’s exercise price is set equal to the closing price of 374Water common stock on the Nasdaq on the grant date.

Key Details

• Transaction date: July 1, 2026; Filing date: July 8, 2026 (filed 7 days after grant).

• Shares owned after transaction: Not disclosed in this Form 4.
• Footnote F1 (option): 25% vests immediately (37,500 shares); remaining 75% (112,500 shares) vests in 12 equal quarterly installments of 9,375 shares starting Oct 1, 2026 (final installment may be rounded). Exercise price = Nasdaq closing price on grant date.
• Footnote F2 (RSUs): 25% vests immediately (31,250 shares); remaining 75% (93,750 shares) vests in 12 equal quarterly installments of 7,813 shares starting Oct 1, 2026 (final installment rounded to reach 93,750 aggregate).
• Filing timeliness: The Form 4 was filed on July 8 for a July 1 grant. Form 4s are generally due within two business days of a reportable transaction, so this filing appears later than the typical reporting window.

Context

• These were compensation awards (an option grant and RSUs), not open‑market purchases or sales. The option grant creates a right to buy shares at the specified exercise price in the future; RSUs convert to shares as they vest. Immediate 25% vesting provides some near‑term ownership; the remainder vests quarterly over three years.
