Wieser's contract will end on December 31, and Deissner is expected to take over from Feb. 1, 2023 the statement said.

Wieser was involved in the takeover of the remaining shares in Media Markt and Saturn from the Kellerhals family. Under the deal, the Kellerhals family's vehicle Convergenta will become an anchor minority shareholder in Ceconomy.

Reuters reported in August that Wieser was considering leaving the firm but the terms were still being negotiated.
