On October 5, 2022, we entered into definitive agreements to sell three Prospect facilities located in Connecticut to Yale New Haven Health ("Yale") for approximately $457 million. This transaction is expected to close in 2023 subject to certain regulatory approvals and the completion of Yale's acquisition of the hospital operations from Prospect.
