“Forest Pharmaceuticals deliberately chose to pursue corporate profits over its obligations to the F.D.A. and the American public,” Carmen Ortiz, the U.S. attorney for Massachusetts, said when the settlement was announced.
The company denied the allegations. In a statement at the time, Mr. Solomon said, “We remain dedicated to ensuring that we operate in full compliance with all laws and regulations.”
In 2011, Forest Labs won a proxy fight against the shareholder activist Carl C. Icahn, who had argued that the company had, among other things, lost billions of dollars of shareholder value over the previous decade. Mr. Icahn continued to pursue Forest Labs with a second proxy fight in 2012, which ended with one of his nominees elected to the company’s board.
In a letter to Mr. Icahn during that fight, Mr. Solomon wrote: “Your discourse thus far has shown a striking lack of strategic ideas. Instead, it has been replete with wild and baseless accusations, innuendo and distortion of facts.”
Still, at some point, Mr. Solomon reached out to Mr. Icahn, and they had a series of dinners.
“We got friendly,” Mr. Icahn said in a phone interview. “I thought he was a nice gentleman, a courtly guy.” He added: “I didn’t agree with the way he ran the business necessarily, but he was a nice guy who was thrilled with the outcome. He made a lot of money.”
In 2013, Mr. Solomon announced his retirement as chief executive and was replaced by Brent Saunders, an executive friendly with Mr. Icahn. Then, in early 2014, Actavis (now Allergan) paid $25 billion to acquire Forest Labs. Mr. Solomon, still the chairman, left after the acquisition and formed a family investment firm with his younger son, David, who had been a Forest Labs executive.
In addition to his sons, Mr. Solomon is survived by his wife, Sarah Billinghurst Solomon, a former assistant general manager of artistic affairs at the Metropolitan Opera, and five grandchildren. His first wife, Carolyn (Bower) Solomon, died in 1991.
