How this market cap is arrived at
| Shares outstanding | 4,918,452,416 |
| Basis | sum of separately listed lines |
| As of | 2026-06-30 |
| Source | Atlas Copco AB Q2 2026 report, Parent Company section "Distribution of shares" |
| class A | 3,357,576,384 × 207.9 SEK (ATCO-A.ST) |
| class B | 1,560,876,032 × 181 SEK (ATCO-B.ST) |
| Priced on | close 2026-08-28, converted at the ECB reference rate |
| Market cap | $103bn |
Two-price problem: A and B shares have identical economic rights (same dividend) but different votes, and they trade at materially different prices - ATCO-A.ST ~SEK 207.9 vs ATCO-B.ST ~SEK 181.0, a ~13% B discount. Correct market cap = 3,317,960,406 x P(A) + 1,560,876,032 x P(B) ~= SEK 972bn; multiplying the total 4,878,836,438 by the A price alone gives ~SEK 1,014bn, about 4.3% too high. The class A and class B lines are separately listed in Stockholm and trade at different prices, so each is priced on its own line.
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 (ATLKY), where one receipt represents 1 ordinary share; the price is put on an ordinary-share basis before it meets the share count.
