Half-Life of the Truth? Complaint Alleges NuScale Misled Investors on ENTRA1

NuScale told investors its small modular reactors were the future of clean energy.

A game changer. A faster, safer path to nuclear power. And they had the perfect partner to make it happen.

Starting in May 2025, NuScale pointed to ENTRA1 as its exclusive global commercialization partner. Executives called it a one stop shop. A seasoned energy platform. A team with decades of experience building and financing major power projects.

In September 2025, ENTRA1 announced a massive deal with the Tennessee Valley Authority. Up to six gigawatts of nuclear power. NuScale celebrated. The stock traded above $57 a share during the Class Period.

Then November hit.

NuScale revealed it had paid ENTRA1 about $495 million in milestone payments tied to that deal. Quarterly losses exploded to more than $530 million. Analysts started asking a simple question. Had ENTRA1 ever actually built or operated anything?

Reports said no. Just three employees. No track record in nuclear. The stock plunged more than 70% from its high.

Now, investors are joining the lawsuit.
