Insights

Equity Ownership and Governance Analyst

Director‑related entity sold 200,000 NPWR shares at a weighted average price near $2.94, modestly trimming but not exiting a large indirect position.

The filing shows that **NPEH, LLC**, an entity linked to NET Power director **Damian R. Beauchamp** through **8 Rivers Capital, LLC**, sold **200,000** shares of **Class A Common Stock** on 11/28/2025. The weighted average sale price was about $2.9354, with individual trades between $2.885 and $3.015. After this sale, NPEH still indirectly holds **2,900,000** shares, so this is a position reduction rather than an exit.

Control and beneficial ownership are layered: 8 Rivers manages NPEH and holds about 90.9% of its equity, and Mr. Beauchamp independently indirectly owns about 68.5% of 8 Rivers. Both 8 Rivers and Mr. Beauchamp expressly disclaim beneficial ownership beyond their pecuniary interests, which is standard language to limit legal inferences about control. The form does not indicate use of a Rule 10b5‑1 trading plan, so this appears as a discretionary sale by the NPEH vehicle.

This transaction modestly reduces the director‑linked indirect stake while leaving a substantial block of **2.9 million** shares still held via NPEH. Points to watch include any repetition or scaling up of similar sales in future Forms 4 and changes in the reported indirect holdings of NPEH, 8 Rivers, or Mr. Beauchamp over the coming quarters.
