SOLV Energy, Inc. Schedule 13G: a group of affiliated American Securities entities jointly reports large shared voting and dispositive power over Class A common stock based on direct holdings and convertible LLC Interests.
The filing lists 115,348,571 shares of Class A common stock outstanding as of March 24, 2026 and states ownership figures that assume conversion of LLC Interests on a one‑for‑one basis. Examples: ASP Manager Corp. holds 174,776,147 shared voting/dispositive power (reported 88.1%); ASP VIII Alternative Investments Solstice, L.P. holds 91,573,571 shared voting/dispositive power (reported 79.4%).

Insights
Joint filing shows concentrated voting power within American Securities affiliates.
The Schedule 13G details shared voting and dispositive power across multiple affiliated entities, driven by direct Class A shares and substantial LLC Interests that may convert one‑for‑one into Class A common stock pursuant to the LLCA. The filing quantifies ownership using March 24, 2026 outstanding shares as a base.
The operative dependency is the LLCA redemption/conversion mechanism and the assumed exchange of LLC Interests for Class A shares. Future filings or redemptions would clarify actual conversion timing and cash vs. share settlement; until then, the filing reports potential voting concentration based on the conversion assumption.

"shares of Class B common stock of the Issuer also held by the Reporting Person"
A class B common stock is one of multiple types of a company’s ordinary shares that carries specific rights—often different voting power or dividend priority—compared with other classes. For investors it matters because those differences affect how much influence you have over company decisions, the income you might receive, and how freely the shares trade; think of it like owning a car with different keys: some keys let you start the engine and open the trunk, others only unlock the door.

In reference to Rows 6, 8 and 9 above, amounts consist of 52,201 shares of Class A common stock, par value $0.0001 per share ("Class A common stock), of SOLV Energy, Inc.

Upon a redemption of LLC Interests, an equal number of shares of Class B common stock of the Issuer also held by the Reporting Person will be surrendered to and cancelled by the Issuer for no additional consideration. Each share of Class B common stock entitles the holder thereof to one vote per share but carries no economic rights.
