NuScale Power Stock: Buy, Sell, or Hold?

In This Article:

NuScale Power (NYSE: SMR) has taken its investors on a wild ride since its public debut. The producer of small modular reactors (SMRs) went public by merging with a special purpose acquisition company (SPAC) on May 3, 2022, and its stock started trading at $10.70 per share. It rallied as high as $15 over the following four months.

But by January 2024, NuScale's stock had sunk below $2. Like many other SPAC-backed companies, it lost its luster as it missed its pre-merger targets and racked up steep losses. Rising interest rates also popped its bubbly valuations as it lost a major deal and faced regulatory headwinds. Yet NuScale's stock subsequently rallied about 1,400% and now trades at $30. Let's see why it soared -- and if it's the right time to buy, sell, or hold this volatile stock.

Why did the bulls retreat from NuScale?

NuScale produces the only SMRs that have been certified with a Standard Design Approval (SDA) from the U.S. Nuclear Regulatory Commission (NRC). These reactors, which are installed in vessels with a diameter of just 9 feet (2.7m) and a height of 65 feet (20m), can be deployed in areas that aren't suited for larger nuclear reactors. NuScale's designs are modular, which means its pieces are pre-fabricated, delivered, and assembled on site.

That approach could significantly reduce the costs and deployment time for a working nuclear reactor. However, NuScale's NRC certification only covers the construction of a reactor that can generate 50 megawatts of electricity. For its SMRs to be more cost-effective and replace coal-fired power plants, NuScale needs its reactor clusters to generate at least 77 megawatts of electricity. It's expecting the NRC to certify the SDA for its 77-megawatt reactors, which will take up about 1% of the space of a conventional reactor generating just as much power, in 2025.

That plan sounds promising, but NuScale has struggled with growing pains over the past two years. In 2023, it canceled a plan to build six nuclear reactors across Idaho through 2030 amid skyrocketing costs. It laid off 40% of its workforce at the beginning of this year, and the U.S. Securities and Exchange Commission (SEC) subsequently launched a probe into its employment, severance, and confidentiality agreements.

A prolific short seller, Iceberg Research, repeatedly accused NuScale of signing deals with "fake" customers and misleading its investors about the certification roadmap for its 77-megawatt reactors. NuScale has also increased its share count by more than 130% since its public debut to raise more funds and cover its stock-based compensation.
