Big Tech companies are scrambling to secure electricity for the long term. For many, this means investing in nuclear power generation.

Constellation Energy Corp.’s Clinton Clean Energy Center in Rural Harp Township, Ill., will supply energy to Meta Platforms Inc. under an agreement announced by the companies on June 3.

Meta Platforms Inc.’s big nuclear energy contract with Constellation Energy Corp. is the latest in a slew of deals by Big Tech players, including Amazon.com Inc., Microsoft Corp. and Alphabet Inc., to secure enough electricity to support the development of generative-artificial-intelligence technology.

And that means it is time to screen stocks in the nuclear-energy space to see which ones analysts believe have the most upside potential.

Early on Tuesday, Meta announced a 20-year deal through which Constellation Energy will provide the social media giant with electricity generated at the Clinton Clean Energy Center — a nuclear-power plant in Rural Harp Township, Ill.

Shares of Constellation rose 1.4% in morning trading, while Meta’s stock was down slightly.

In order to screen stocks of companies involved in nuclear power generation, as well as providers of related equipment and services, we began with a list of stocks held by four exchange-traded funds that track indexes designed to track nuclear-related industries using a variety of approaches:

• The Global X Uranium ETF (URA) has $3.2 billion in assets under management (AUM) and holds 47 stocks of companies involved in uranium mining and the manufacturing of nuclear components. This fund was established in November 2010, and its annual expenses come to 0.69% of assets under management. The portfolio is weighted by market capitalization, with maximum levels set according to how much of a “pure play” each company is within the nuclear space. The underlying index is rebalanced quarterly.

• The VanEck Uranium & Nuclear ETF (NLR) has $1.2 billion in AUM, was established in August 2007 and holds 25 stocks. The underlying index is designed to track the overall performance of companies involved with uranium mining, construction of nuclear reactors and nuclear power generation. According to FactSet, the fund “heavily overweights utilities and carries little weight in [the energy sector], giving it a large-cap tilt.” This fund’s expense ratio is 0.56%.

• The Range Nuclear Renaissance Index ETF (NUKZ) has $256 million in AUM, holds 44 stocks weighted by market cap with limits meant to ensure that the portfolio is diverse by industry and geography. The fund was established in January 2024. The fund’s expense ratio is 0.85%.

• The Themes Uranium & Nuclear ETF (URAN) has $6 million in AUM. This fund was launched in September and its expense ratio of 0.35% is the lowest among the funds listed here. URAN holds 33 stocks to track the BITA Global Uranium and Nuclear Select Index, which is weighted according to the index provider’s thematic-exposure score, based on revenue derived from nuclear-related industries.

While URA doesn’t hold shares of any utilities, Constellation Energy is the largest holding for each of the other ETFs. It makes up 9.1% of the NLR portfolio, 9.5% of NUKZ and 10.2% of URAN.

A nuclear stock screen

Together, the four nuclear-focused ETFs hold 91 stocks. For a list of companies that are widely followed, we have pared the group to 48 that are each covered by at least nine analysts working for brokerage of research firms polled by FactSet.

Among the remaining stocks with majority “buy” or equivalent ratings, these 10 have the most upside potential over the next year, based on the consensus price targets. Share prices and targets are in local currencies where the stocks are listed.

Before buying any individual security, you should do your own research and form your own opinion about how likely a company is to grow and remain competitive over the long term. One way to begin that process is to click the tickers for more about each company.

Despite being favored by 14 of 19 analysts covering the stock, Constellation Energy didn’t make the list. The stock closed at $313.43 Monday and was already 2% above the consensus price target of $307.77.
