Simultaneously with this sale the Company purchased buildings and operated an addiction treatment center in Delray Beach, Florida under its Addiction Recovery Institute of America subsidiary with a license obtained in December 2016, initially through owned properties in Delray Beach and subsequently though leased properties in West Palm Beach, Florida. Since June 30, 2020, the Company has been actively involved in the management of a treatment center operated by Evernia in West Palm Beach, Florida. On July 1, 2021, the Company closed on the acquisition of 75% of ATHI, which owns 100% of Evernia, once the probationary approval of a license was obtained from the Department of Children and Family Services of Florida.
