SMR Stock: Q2 Earnings Snapshot

NuScale Power reported second-quarter (Q2) 2026 earnings in August, posting revenue of $75,000, down roughly 99% year-over-year from $8.1 million. The decline was primarily due to the impact of the completion of front-end engineering design (FEED) work for its RoPower project in Romania. 

The company’s adjusted loss per share of $0.13 matched Wall Street estimates. 

Despite the sharp revenue decline, NuScale ended the quarter with approximately $1.9 billion in cash, cash equivalents and investments, strengthening its liquidity by around $900 million from Q1 following capital-raising and other financing actions.
