Fluor's stock surged 5.78% during intraday trading on Tuesday, marking a significant upward movement for the engineering and construction company.

The sharp rise appears to be primarily driven by the company's announcement that it has received $1.35 billion from the sale of 71 million shares of NuScale Power. Furthermore, Fluor has launched a trading program to monetize its remaining 40 million NuScale shares, with completion expected in the second quarter of 2026. This substantial cash infusion is a key factor behind the positive investor sentiment.

Additional supportive factors include the company reporting a robust backlog of $25.5 billion and providing forward-looking guidance for fiscal year 2026 adjusted EBITDA in the range of $525 million to $585 million. The announcement of a share buyback plan may have also contributed to the optimistic market reaction.
