Fundamentals iCompany financials — revenue, earnings, margins — from the newest filings shown, each carried with its date.iAs-reported figures and standard ratios from FMP, as of 2026-07-25. Revenue, net income and free cash flow can toggle annual or quarterly; margin, ROE and debt-to-equity are shown by fiscal year. We report the figures and the trend — no target price and no over/under-valued call. More on /methodology.
Fair value — three views iIndependent reference estimates of worth (a cash-flow model, peer multiples, analyst targets), shown as separate views — not a single verdict.
iThree independent estimates of per-share value, each by a different method and each with its own assumptions: a discounted-cash-flow intrinsic value, a peer comparable (the median trailing P/E of 74 sector peers times this company's trailing EPS), and the analyst price-target consensus. They routinely disagree — that gap is the point. We show the three marks and the current price; we do not blend them into a single number or call the stock over- or under-valued.
