06:28 AM EDT, 10/21/2025 (MT Newswires) -- Fluor (FLR) shares were up 6.6% pre-bell Tuesday after The Wall Street Journal reported that Starboard Value has amassed a roughly 5% stake in the engineering and construction company and intends to push for ways to boost the stock value.

The activist investor is of the opinion that Fluor's core business is being undervalued in the market relative to its value that investors are attributing to its stake in NuScale Power ( SMR ) , the unnamed sources told the news outlet. Starboard believes Fluor should weigh options for its interest in NuScale, including a potential sale, according to the Monday report.

Starboard thinks that Fluor should take advantage of new government policies under President Donald Trump and that the company is well placed in a market where many of its competitors have actually exited the construction industry, the WSJ reported.

Fluor, Starboard, and NuScale didn't immediately respond to MT Newswires' requests for comments.

NuScale shares were down 4.9% in recent premarket activity.
