Top Utilities Stocks by Revenue

Top utilities companies ranked by revenue, latest annual filings.

What Revenue Means for Utilities Companies

Revenue in utilities is dollars billed to customers for regulated electricity, gas, or water service, along with smaller amounts from unregulated generation and energy services. Because most utility revenue flows through rate structures set by state commissions, the top line grows largely in line with the approved rate base, customer count, and allowed pass-through of fuel costs, rather than through market pricing decisions.

Why It Matters in Utilities

Utility revenue is typically among the most stable in the market because regulated monopoly service areas and cost-of-service ratemaking produce predictable cash flows that support long reinvestment cycles. Still, revenue growth is constrained by regulation: commissions ultimately decide how much of a utility's capital investment earns a return, and adverse rulings, disallowed costs, or slower-than-expected rate-case outcomes can compress top-line growth even as the company keeps spending capex.

What to Read Alongside

Pair revenue with [Capex](/financials/biggest-capex-stocks/utilities/) to understand rate-base growth that drives future earnings, [Free Cash Flow](/financials/top-free-cash-flow-stocks/utilities/) for self-funding capacity against dividend commitments, and [Debt](/financials/most-indebted-stocks/utilities/) since leverage is structurally high and shapes financial flexibility.

How this ranking is built

Companies are ranked by revenue as reported in their most recent annual filing with the SEC. Figures shown are in US dollars (or percent, as noted), rounded to two decimals.

  • Source: annual 10-K / 20-F filings from companies trading on US exchanges (NYSE, Nasdaq, AMEX).
  • Fiscal year: whichever annual period the company has most recently filed. Fiscal years don't always align with the calendar year, so the "as of FY" stamp above reflects the most common year across the table.
  • Filtered out: warrants, preferred shares, and duplicate listings that share a parent company's financials.
  • Update cadence: refreshed as companies file new annual reports (typically within 60–90 days of fiscal year end).
