Latest fiscal year per company: ASML FY2025, KLA FY2026. Fiscal years end on different dates, so years are not calendar-aligned.
ASML reports in EUR and KLA in USD. Amounts are never converted between currencies, so revenue and free cash flow are shown in each filing currency and their size is not compared; margins, growth and percentages of revenue are ratios within one filing and are comparable.
Why this pair: Lithography and process control; reported in EUR and USD, so revenue size is not compared. Peer groups are curated by hand from each company's business as described in its own 10-K/20-F (what it sells, not its SIC code). A company can sit in more than one group. Within a group, a pair is listed when both companies report in the same currency and the larger company's latest fiscal-year revenue is at most 4x the smaller one's; each company keeps its 4 nearest peers by revenue ratio. Companies reporting in different currencies are never size-matched (amounts are not converted); a short list of obvious same-industry pairs across currencies is added by hand, with the reason, as are two direct competitor pairs outside the size rule (AMD vs NVIDIA, Intel vs NVIDIA).

Definitions: Revenue = Total revenue; Revenue growth (1 year) = Revenue FYt ÷ revenue FYt−1 − 1; Revenue growth (3-year CAGR) = (Revenue FYt ÷ revenue FYt−3)^(1/3) − 1; Gross margin = Gross profit ÷ revenue; Operating margin = Operating income ÷ revenue; Net margin = Net income ÷ revenue; Free cash flow = Operating cash flow − capital expenditures (one formula for all companies); FCF margin = Free cash flow ÷ revenue; R&D as % of revenue = Research and development expense ÷ revenue; Stock-based compensation as % of revenue = Stock-based compensation ÷ revenue.
