What happened: American Electric Power (AEP), with its extensive U.S. transmission system, and GE Vernova, serving 25% of global electricity needs, are prominent utility stocks. AEP's market cap of $70.3 billion places it among large-cap utilities. Ameren (AEE), with a $30.3 billion market cap, operates in electric and natural gas utilities. Sempra Energy, with $13.7 billion in 2025 revenues, has seen its shares outperform the Utility ETF.
