CVS Health (NYSE: CVS) today announced that it has entered into an agreement with the U.S. Department of Justice (DOJ) that allows it to proceed with its proposed acquisition of Aetna (NYSE: AET). DOJ clearance is a key milestone toward finalizing the transaction, which is also subject to state regulatory approvals, many of which have been granted. CVS Health’s acquisition of Aetna remains on track to close in the early part of Q4 2018.

“DOJ clearance is an important step toward bringing together the strengths and capabilities of our two companies to improve the consumer health care experience,” said CVS Health President and Chief Executive Officer Larry J. Merlo. “We are pleased to have reached an agreement with the DOJ that maintains the strategic benefits and value creation potential of our combination with Aetna. We are now working to complete the remaining state reviews.”

Merlo added, “CVS Health and Aetna have the opportunity to combine capabilities in technology, data and analytics to develop new ways to engage patients in their total health and wellness. Our focus will be at the local and community level, taking advantage of our thousands of locations and touchpoints throughout the country to intervene with consumers to help predict and prevent potential health problems before they occur. Together, we will help address the challenges our health care system is facing, and we’ll be able to offer better care and convenience at a lower cost for patients and payors.”

Following the close of the transaction, Aetna will operate as a standalone business within the CVS Health enterprise and will be led by members of its current management team.

As part of the agreement reached with the DOJ, as previously announced, Aetna entered into an asset purchase agreement with a subsidiary of WellCare Health Plans, Inc. (NYSE: WCG) for the divestiture of Aetna’s standalone Medicare Part D prescription drug plans, which have an aggregate of approximately 2.2 million members. Aetna will provide administrative services to and will retain the financial results of the divested plans through 2019. DOJ’s clearance, subject to this limited divestiture, moves CVS Health closer to realizing the substantial synergies and value expected from the combination.
