Utilities companies that buy back the most stock

Share buybacks are the cash a company spent during the year repurchasing its own stock, taken from the financing section of the cash-flow statement. Most companies buy back nothing at all — the line is absent rather than zero — so this ranking covers the minority that do. Figures are for fiscal year 2025 and are read directly from each company's SEC filings; the source column on every row links to the document.
