Even without a price disclosed, this is one of the biggest deals we’ll probably see in the Behavioral Health Care sector this year.

Bain Capital Private Equity and Diamond Castle Holdings are selling Beacon Health Options, the largest independently held behavioral health organization in the country. The buyer is managed care giant Anthem, Inc. (NYSE: ANTM).

Its service lines incldue clinical mental health and substance use disorder management, a comprehensive employee assistance program, work/life support, specialty programs for autism and depression, and analytics to more than 36 million individuals nationwide.

The combination will also create one of the most comprehensive behavioral health networks capable of offering more accsesible and affordable care for consumers. Beacon will operate within Anthem’s Diversified Business Group. The acquisition is expected to close in the fourth quarter of 2019.
