SIX AB decides on delisting

The Board of Directors has earlier this day resolved to delist SIX AB (publ)’s class B share from First
North.

The Board of Director’s decision is based on the facts that the trading in the company’s class B share
on First North is very limited and that the share is only held by a small number of shareholders
following the public cash offer that was rendered by SIX Group AG’s, former Swiss Financial Market
Services AG, Swedish subsidiary Telekurs Sweden AB and which was declared unconditional on
October 27, 2008.

A formal application to delist will be submitted to First North and the last day of trading with SIX
AB (publ)’s class B share will be publicly announced in connection with First North’s delisting
decision.
