The number of shares in Atlas Copco AB after redemption procedure

Stockholm, Sweden, June 30, 2011: The number of shares outstanding in
Atlas Copco AB was during June decreased to 1 229 613 104 from
2 459 226 208. The change is a result of the share redemption procedure
resolved by the Annual General Meeting on April 20, which has now been
completed.

The share redemption procedure commenced with a 2:1 share split, which
was carried out in May. After the split there were 1 678 788 192 series
A shares (carrying 1 vote per share) in the company and 780 438 016
series B shares (0.1 vote/share).

Half of the shares in each series were redemption shares. All of these
shares were in June redeemed by Atlas Copco for SEK 5 per share. The
number of outstanding shares and votes is now the same as before the
procedure was carried out.
