Blackstone Inc. is in talks about a potential merger of its European building materials retailer with a similar business owned by CVC Capital Partners, people with knowledge of the matter said.

New York-based Blackstone is discussing a possible combination of the business, known as Building Materials Europe BV, with CVC’s Stark Group A/S, the people said. It has also been studying other potential partners alongside concurrent preparations for a listing of BME, they said, asking not to be identified because the information is private.
