NuScale Power's stock plummeted 8.15% during intraday trading, reflecting significant investor concern following the release of disappointing financial results and negative sector sentiment.

The decline was primarily driven by the company's first-quarter earnings report, which revealed a substantial miss on key financial metrics. NuScale Power reported a larger-than-expected loss per share and revenue that fell drastically short of analyst forecasts. The company's net loss also widened significantly compared to the same period last year.

Adding to the selling pressure, a major cornerstone shareholder was reported to have liquidated its entire position in the company, further eroding market confidence. The decline was compounded by broad-based weakness across the Heavy Electrical Equipment sector, with several peer companies also experiencing significant losses during the session.
