Amedisys stock climbed Friday after the provider of home health care agreed to waive its right to terminate a merger agreement with UnitedHealth Group, bolstering expectations that the deal will succeed despite a government attempt to block it. Shares of Amedisys were up 4.7% to $89.97, marking a fifth consecutive days of gains. Amedisys agreed to be acquired for $3.3 billion, or $101 a share in cash, in June 2023, but the Justice Department filed a civil antitrust lawsuit last month, saying the proposal would eliminate competition in the hospice industry.
