Insights

Securities Analyst

Insider purchases documented across two days increased indirect holdings to 3.19M shares.

The Form 4 recordsRule 10b5-1 purchases of 22,085 shares on 08/06/2025 at a weighted-average $13.0112 and 25,104 shares on 08/07/2025 at $12.7104, totaling 47,189 shares. These transactions were executed under a 10b5-1 plan adopted June 5, 2025 and are reported as indirect ownership held of record by Hill City. The filing provides clear purchase sizes and prices but does not provide context such as percentage ownership of outstanding shares or timing rationale, so materiality to shareholders cannot be determined from this Form 4 alone.

Corporate Governance Specialist

Filing emphasizes structured ownership and voting control across multiple entities with standard disclaimers.

The disclosure details a layered ownership chain: Hill City holds the shares of record, with ECP ControlCo as managing member of the general partner entities. The filing names board managers who collectively share voting and dispositive power and includes the customary disclaimer of beneficial ownership except for pecuniary interest. The use of a 10b5-1 plan and the separate filings by related entities are explicitly noted, reflecting procedural compliance and coordination among affiliated filers.
