1 It should be noted that the revenue figures shown here are not equal to the figures in the consolidated financial statements prepared in accordance with German commercial law but instead show the figures of the BDO Group incl. the following companies.

2 The global BDO Network uniformly reports its financial figures for the duration of Oct. 1 until Sept. 30. of the following year. The figures shown here for 2023 are therefore valid for the time period ranging from Oct. 1 2022 until Sept. 30, 2023 and are therefore not entirely comparable to those made in the consolidated financial statements of the BDO AG Wirtschaftsprüfungsgesellschaft as per June 30th, 2023.
