Key Facts on Nuclear Energy Stocks
Constellation Energy, the largest nuclear energy company in the U.S., provides power to approximately 2.5 million customers and services 75% of the Fortune 100. Recently acquiring Calpine, this move diversifies Constellation’s portfolio in the clean energy sector. The company’s 20-year power purchase agreements with Microsoft and Meta are expected to generate predictable long-term revenue.
Cameco, a major player in uranium mining, holds the position of the largest uranium stock by market cap and the second-largest global uranium producer, contributing roughly 24% of the world’s supply. Its strategic advantage stems from ties to U.S. and European nuclear companies, especially given Kazakhstan’s geopolitical landscape.
In contrast, companies like Oklo and NuScale Power are developing Small Modular Reactors (SMRs) but currently lack profitability. While SMRs offer potential cost-effective solutions, investors remain cautious due to the volatility and the companies’ absence of established profits.
