Companies in the United Kingdom with the highest operating cash flow

Operating cash flow is the cash the business itself produced over the year, before anything is spent on new assets or paid out to lenders and shareholders. It strips out the non-cash charges that separate profit from cash. 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.
