    Revenue in constant purchasing power

    USD revenue expressed in 2026-09 consumer-price dollars. Each annual period uses a CPI-U average weighted by the days in its actual reporting interval. This is a purchasing-power comparison, not a company-specific price or volume measure.

    No USD annual revenue periods with complete CPI coverage are available. Non-USD statements are not converted with U.S. CPI.
