Select Water Solutions (WTTR) CEO John Schmitz discloses December insider share sales

Rhea-AI Filing Summary

Select Water Solutions President & CEO John D. Schmitz, who also serves as a director, reported multiple sales of Class A common stock in early December 2025. On December 4, 2025, a family trust sold 187,442 shares at a weighted average price of $11.15, and on December 5, 2025, the same trust sold an additional 62,480 shares at a weighted average price of $11.21. Separate family trusts for six children each sold 3,946 shares on December 4 and around 1,316 shares on December 5 at similar prices.

The filing notes that the sale prices reflect weighted averages for trades executed in ranges between $11.00–$11.27 and $11.09–$11.33, and that detailed trade breakdowns are available on request. It also states that certain indirect holdings for the children’s trusts were adjusted by one share each to correct a prior clerical error.

Insights

Equity Ownership and Governance Analyst

CEO and director reports trust sales around $11 while retaining significant direct and indirect ownership stakes.

The filing shows that **John D. Schmitz**, President, CEO, and director of **Select Water Solutions, Inc.**, executed multiple sales of **Class A Common Stock** on 12/04/2025 and 12/05/2025. The sales occurred primarily through a **Family Trust** and several **Family Trusts for Children**, at weighted average prices of about $11.15 and $11.21, based on trade ranges disclosed in the footnotes. These are open-market sales coded "S" and reduce indirect positions in those trusts.

Despite these dispositions, the reporting person continues to show substantial holdings across several vehicles. There are **544,444** shares held directly, **300,000** through **B-29 Investments, LP**, **539,388** and **539,387** through the two 2024 annuity trusts, **13,126** through **B-29 GP, LLC**, and **1,496,626** through the **Family Trust**, in addition to tens of thousands of shares in each child’s trust. Footnote (5) also reveals a small upward adjustment of one share per child trust to fix a prior clerical understatement, which slightly increases previously reported indirect amounts.

The key practical points to watch are the ongoing pattern and scale of dispositions by this key executive and director, and any further corrections to reported holdings. The weighted-average pricing and trade ranges in notes (3) and (4) give a clear reference for the sale levels during early December 2025. Monitoring future Forms 4 over the next few months can indicate whether these sales represent a one-off rebalancing of trust accounts or a continuing reduction in reported beneficial ownership.
