Clear Street Group Inc. has acquired a new position in NuScale Power Corporation (NYSE:SMR), purchasing 4,322,653 shares valued at approximately $155.62 million. This represents about 1.45% ownership of NuScale Power. The investment comes as NuScale secures its first confirmed commercial deployment in Europe and expands a fuel-supply partnership, bolstering the company's growth and supply chain credibility. However, the news also coincides with a wave of securities class action lawsuits, creating legal overhang and potential damages exposure.

Why it matters

NuScale Power is a pioneering developer of small modular nuclear reactors, a technology seen as crucial for delivering zero-carbon baseload power. Clear Street Group's substantial investment signals confidence in NuScale's growth potential, but the concurrent legal challenges could weigh on the stock's valuation and management's focus.

The details

Clear Street Group acquired the 4,322,653 shares of NuScale Power in the third quarter, making it the company's 11th largest holding. This investment represents about 1.45% ownership of NuScale. The news comes as NuScale secures its first confirmed commercial deployment in Europe through an agreement with RoPower, as well as an expanded fuel-supply partnership with Framatome.
