Hartford HealthCare, one of the two largest health systems in Connecticut, has offered $86.1 million to purchase Manchester Memorial and Rockville General hospitals from Prospect Medical Holdings, the California-based operator that filed for bankruptcy protection in January. ECHN Holdings Inc., a wholly owned subsidiary of Hartford HealthCare, will serve as the “stalking horse bidder” for the two hospitals in the court-supervised sale auction, according to court documents. Prospect Medical Holdings paid $105 million when it purchased the two hospitals in 2016. Hartford HealthCare currently owns a total of seven hospitals across the state, the most of any health system in Connecticut, and earned roughly $6 billion in revenue in 2023. “For years we have been working hard to secure Rockville Hospital’s future and this is a major step towards that,” he said.
