374Water Inc. Stock: price and insider trades · United States

This page follows insider dealings at 374Water Inc. as filed with SEC (Form 4). Over the twelve months to 18 October 2026, the company's managers filed 7 filings, from 4 insiders.

Open-market activity splits into 2 purchases totalling €92k and 3 sales totalling €64k; 2 insiders sit on the buying side and 1 insider on the selling side. On balance, insiders were net buyers of €28k. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Among those who bought: 1 finance chief and 1 chief executive. The largest single trade was a purchase of €88k by Jones Stephen J, published on 17 December 2025.

Compared with its exchange (5,808 companies, median 19 filings), a count of 7 filings is below the norm. The full history, which starts in 2023, counts 18 purchases against 31 sales. On the fundamentals side, the SEC filing (10-K) for the period ending 31 December 2025 lists revenue at 215,037 USD and net income at -21.0 m USD.

In all, 1 purchase was made within 30 days of a purchase by another insider of the company. Purchases made close together by different insiders form what is called a cluster. The last purchase on record was published on 18 December 2025, which is 304 days ago. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. Section 16 rules allow two business days to file each Form 4. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify.
