Recent capital reduction: Siemens cancelled 18,000,000 treasury shares in March 2026, taking capital stock from the long-standing 800,000,000 down to 782,000,000 - any share count sourced before March 2026 (including the Feb-2026 AGM notice) is 2.3% too high. Treasury still held: EUR 1,994m at cost at 30 June 2026 (vs EUR 3,520m at 30 Sep 2025); Q3 FY2026 weighted-average shares outstanding (basic) were 774,050 thousand, first nine months 777,542 thousand - use ~774m for an outstanding-basis market cap.
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 (SIEGY), where one receipt represents 0.5 ordinary shares; the price is put on an ordinary-share basis before it meets the share count.
