Every figure above comes from the company profiles linked below, where each revenue number carries its fiscal year and source. Run-rates are never used as annual revenue, and revenue reported in other currencies is converted to US dollars at approximate 2025 average rates, so treat the comparison as an order of scale rather than an exact gap.
