Correction of the periodic report for the third quarter of 2012

Current report 55/2012 dated 22.11.2012

Legal basis: Article 56 (1) (2) of the Act on Public Offering — current and periodic information

The Management Board of ATM S.A. would like to inform you that incorrect comparative data for 2011 were disclosed in the periodic report for the third quarter 2012. This is due to the fact that the dividend of PLN 4 million received from ATM SI S.A. in the third quarter 2011 should have been disclosed as revenues from discontinued operations, rather than financial revenues, since it referred to shares held in ATM SI S.A. that were classified to discontinued operations in 2012.

As a result of correction of this mistake, “Financial revenues” for the period 01/01-30/09/2011 and for the period 1/07-30/09/2011, disclosed in the consolidated and individual statements of total income would be reduced by PLN 4 million, while “Net profit on discontinued activity” shall be increased by the same amount. Net profit amount would not change.

All amendments to the report resulting due to this correction are as follows:
