Clarus, the holding company previously registered as Black Diamond, has finally made an acquisition, paying $79 million for a highly profitable U.S. firm, Sierra Bullets, whose proprietary manufacturing process is said to give it the tightest tolerances in the ammunition market. The purchase price is equal to 6.3 times the $12.5 million in Ebitda generated by Sierra last year on sales of $32 million. The transaction is expected to be immediately accretive to the results of Clarus, which will be able to make its huge net operating loss carryforwards to good use, while helping Sierra to become more international. It will also add it to its digital platform.
