Values are as tagged by the issuer in XBRL. Revenue for banks and insurers is net of interest expense where that is the reported line. Fiscal years that do not follow the calendar are shown by their period-end date. No price, market cap, or valuation multiple is shown because Yield Theory does not republish unlicensed market data.
Diluted EPS is the earnings figure behind the price-to-earnings ratio; the P/E multiple compression calculator shows how a change in that multiple moves a share price. Shares outstanding multiplied by the share price gives market capitalization.

Each question starts with what the filings show, then why it matters. None of these is a rating or a forecast.
Operating cash flow was $758M, 0.94 times net income of $806M, for the fiscal year ended December 31, 2025.
Cash from operations trailed reported earnings. Working-capital build (receivables, inventory, prepayments) or non-cash gains are the usual reasons; check the cash-flow statement before relying on reported profit.
Net income was 15.5% of revenue for the fiscal year ended December 31, 2025, based on revenue and net income reported for the same period.
Net margin reflects the business model as much as execution, so compare it with companies in the same SEC industry and read the income statement for one-time items before treating it as a run rate.
