What Is The Lawsuit About?

The lawsuit has been filed on behalf of investors who purchased securities during the period of May 13, 2025 through November 6, 2025, inclusive (“the Class Period”). Prior to the start of the class period, NuScale entered into a global commercialization partnership with ENTRA1 Energy LLC (“ENTRA1”). The Company claimed that this critical partnership would allow the Company to take its NuScale Power Modules (“NPM”) technology from development to deployment, enabling NuScale’s NPMs to serve as meaningful, revenue-generating components in power plants.

The lawsuit alleges that (i) ENTRA1 had never built, financed, or operated any significant projects, let alone projects in the highly technical and complicated field of nuclear power generation, during its entire operating history; (ii) NuScale had entrusted its commercialization, distribution, and deployment of its NPM and hundreds of millions of dollars of NuScale capital to an entity that lacked any significant prior experience owning, financing, or operating nuclear energy generation facilities; (iii) the purported experience and qualifications attributed to ENTRA1 by defendants during the class period in fact referred to the purported experience and qualifications of the principals of the Habboush Group, a distinct entity without significant experience in the field of nuclear power generation; and (iv) as a result, NuScale’s commercialization strategy was exposed to material, undisclosed risks of failure, delays, regulatory challenges, or other negative setbacks.

On November 6, 2025, NuScale revealed that the Company’s general and administrative expenses had grown over 3,000% to $519 million during its third fiscal quarter, up from $17 million in the prior year period, due largely to NuScale’s payment of $495 million to ENTRA1 for its TVA agreement. As a result, NuScale’s quarterly net loss rose to $532 million, up from $46 million in the prior year period. On this news, the price of NuScale shares declined by $5.45 per share, or approximately 14.4%, from $37.91 per share on November 5, 2025 to close at $32.46 on November 6, 2025.

The price of NuScale stock continued to fall in subsequent days, dropping to a low of $17 per share by November 21, 2025, more than 70% below the class period high of more than $57 per share.
