NuScale Faces Securities Class Action Over ENTRA1 Disclosures as Investors Eye Lead‑Plaintiff Bid

The case is in the pre‑certification stage with plaintiff firms recruiting investors to seek the lead role.

Overview

Robbins Geller says the filed case, Truedson v. NuScale Power Corporation (No. 26‑cv‑00328, D. Or.), names NuScale, certain executives, and Fluor Corporation under the Securities Exchange Act of 1934.
Plaintiffs allege NuScale misled investors about ENTRA1’s capabilities and entrusted commercialization of its small modular reactor program and significant capital to a partner lacking nuclear project experience.
The complaint cites ENTRA1’s September 2, 2025 announcement with TVA as key context for NuScale’s commercialization narrative and projected deployment of NuScale Power Modules.
On November 6, 2025, NuScale disclosed $519 million in G&A expenses driven largely by a $495 million payment to ENTRA1, reporting a $532 million quarterly loss and a share price decline of more than 12% over two trading days.
Robbins Geller, Rosen Law Firm, and the Law Offices of Howard G. Smith are inviting NuScale shareholders who bought Class A stock from May 13 to November 6, 2025 to contact them about participating or seeking lead‑plaintiff status.
