Green marks the reading conventionally read as cheaper or stronger on that row — a direction, not a recommendation, and the two companies frequently win different rows. * Price-based multiples are a snapshot taken 2026-09-09; the rest come from filed accounts. A dash means the measure could not be computed — each company page says why.
