Top Utilities Stocks by Free Cash Flow

Top utilities companies ranked by free cash flow, latest annual filings.

What Free Cash Flow Means for Utilities Companies

Free cash flow in utilities is shaped by the regulated rate base and the capex programs that expand it. Operating cash flow tends to be unusually predictable because revenues are set by regulators to cover allowed costs plus a return on invested capital. That same regulation, however, pushes capital expenditure high and relatively fixed, which means reported free cash flow is often negative or modest even when the underlying business is performing exactly as expected.

Why It Matters Less in Utilities

For utilities, negative free cash flow is not by itself a warning sign: heavy capex builds the rate base that future earnings are calculated from. The more useful lens is funds from operations against capex, plus the regulatory allowed return. What matters for investors is usually the stability of operating cash generation and the size and approved status of the capex pipeline, both of which shape future earnings and dividend capacity over many years.

What to Read Alongside

Pair free cash flow with Net Income for regulated earnings levels after allowed depreciation, Share Buybacks for any capital returns beyond the steady dividend, and Revenue for the scale of the regulated customer franchise.

How this ranking is built

Companies are ranked by free cash flow 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).
