It has agreed terms with the family-owned Rolland business, which makes branded, own-label and licensed ice cream products for French customers such as Carrefour, Metro and E. Leclerc, as well as Tesco.
If approved by the French Competition Authority, the deal will increase R&R's turnover from about 400m to more than 500m, creating the second-largest ice cream group for supermarket sales in the UK, Germany and France, said R&R chief executive James Lambert.
The deal marks the start of an ambitious expansion plan for R&R, which was created in 2006 when Richmond Ice Cream merged with Italian supplier Roncadin.
"This acquisition marks an important stage in our strategy to grow our company on mainland Europe," Lambert added. "The ice cream manufacturing sector continues to consolidate and this will result in further growth opportunities. I fully expect to be announcing more acquisitions soon."
