Top Companies by Operating Cash Flow — Energy

Trailing twelve months (TTM) operating cash flow (OCF) is the cash a company generated from running its core business over its four most recent fiscal quarters. It starts from net income and adds back non-cash charges like depreciation and stock-based compensation, then adjusts for changes in working capital — so it reflects cash actually collected, not accrual-based profit.

OCF is the root of free cash flow: subtract capex and what's left is available for buybacks, dividends and debt reduction. Comparing OCF with net income reveals earnings quality — persistently higher OCF signals conservative accounting. Figures are ranked in USD after period-average FX translation (IAS 21).
