GlaxoSmithKline is nearing a deal to acquire Stiefel Laboratories, a US maker of skin care pharmaceuticals, for about $3bn. A deal between UK-based GlaxoSmithKline and privately-held Stiefel, controlled by the Stiefel family and part-owned by buyout group Blackstone, could be announced as early as Monday, although the two companies were still discussing terms of an agreement on Sunday.
