Single class. 5,711,848,120 includes 12,798,731 treasury shares (small, ~0.2%); ex-treasury count is 5,699,049,389. Critical: 4-for-1 share split with record date 31 Dec 2025, effective 1 Jan 2026 - any share count sourced before 2026 (roughly 1.43bn shares) is 4x too small, and unadjusted price history before Jan 2026 is 4x too high.
Share counts move on a filing cadence, prices move continuously — so this figure is exact only as of the two dates above, and we publish both rather than a single undated number. This company is quoted here through a depositary receipt (SFTBY), where one receipt represents 0.5 ordinary shares; the price is put on an ordinary-share basis before it meets the share count.
