Figure is already net of five completed buybacks (56,140,350 shares extinguished 2017; 76,190,476 in 2018; 53,333,333 in 2021; 40,000,000 in 2022; 40,963,855 in 2023) - Indian buybacks extinguish shares, so there is no treasury stock to add back. TCS does not issue fresh equity for employee plans, so the count has been static since Dec 2023 and should not drift. No ADR or GDR programme - TCS is not listed or quoted in the US.
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. Provenance.
