United Homes Group’s controlling shareholders have updated their ownership and governance details and confirmed support for a planned merger. Michael P. Nieri reports beneficial ownership of 41,186,045 Class A common shares on an as-converted basis, representing 69.4% of the class, through direct holdings, options, Class B shares and family trusts.
The reporting persons together may be deemed to beneficially own 42,455,327 Class A shares, or 71.2% of the Class A shares outstanding, based on 21,853,341 Class A shares as of March 10, 2026. The amendment reflects trustee changes in the Nieri family trusts and notes that Nieri and affiliates holding about 80% of total voting power have already delivered written consent approving a merger in which United Homes Group will become a wholly owned subsidiary of Stanley Martin Homes, LLC.

Insights
Nieri family confirms super‑majority control and formal backing of UHG’s merger.
This amendment details how Michael P. Nieri and related trusts and entities collectively control most of United Homes Group through Class A and higher‑vote Class B shares. It clarifies precise beneficial stakes and trustee roles across multiple Nieri family vehicles.
A key point is that the reporting persons may be deemed to own 42,455,327 Class A shares, or 71.2% of the outstanding Class A, while Nieri and certain affiliates hold about 80% of total voting power. That concentration enables them to approve major corporate actions unilaterally.
The filing notes they have already executed written consent adopting the Merger Agreement under which United Homes Group will merge into a subsidiary of Stanley Martin Homes, LLC, leaving UHG as a wholly owned subsidiary. Future company disclosures about the merger’s closing and consideration will frame how this control position translates into outcomes for minority shareholders.

This Amendment No. 6 is being filed to remove R.

Nieri to reflect the vesting of options and Pennington W. Nieri to reflect the forfeiture of options and acquisition of shares, all disclosures set forth in the Initial Schedule 13D, as amended by Amendment No. 1, Amendment No. 2, Amendment No. 3, Amendment No. 4, and Amendment No. 5, are materially unchanged.
