OTI Greentech AG: Publication of annual and consolidated financial statements and Annual General Meeting for fiscal year 2021 postponed once again

Berlin, August 30, 2022 – OTI Greentech AG (ISIN DE000A2TSL22), an international provider of innovative and sustainable chemical products and services for industry, listed on the Düsseldorf Stock Exchange, announces that the Management Board and Supervisory Board have decided to publish the annual and consolidated financial statements for fiscal year 2021, on September 21, 2022. The Annual General Meeting for fiscal year 2021 will take place on November 4, 2022. The further postponement of the dates has become necessary because the required audit work for the first consolidation of the US subsidiary KMI Cleaning Solutions, Inc. acquired in 2021 is significantly more extensive than planned. There are no operational reasons for the postponement; preliminary figures for fiscal year 2021 had already been published by OTI Greentech on May 24, 2022.
