A.H.Robbins became part of American Home Products in 1989, which in turn was acquired by Wyeth in 2002. In 2004, SPL was spun out of Wyeth as an independent company. Its stock was first held by financial investors Arsenal Capital Partners, then in 2006 by American Capital Strategies. In 2013, SPL was acquired by Shenzhen Hepalink Pharmaceutical Company, a leading heparin manufacturer in China.
