Closing of the merger is subject to customary closing conditions. The current owners of GfK SE, Nürnberg Institut für Marktentscheidungen e.V. (NIM) und Acceleratio Topco S.C.A., a holding company owned by funds advised by KKR, remain invested in the combined company as significant shareholders. Advent International will hold the majority. Advent International had acquired NielsenIQ in 2021.
