UnitedHealth Group expects its nearly $8 billion acquisition of Change Healthcare to close in early 2022, executives told investors on Thursday. Chief Operating Officer Dirk McMahon said on the company's earnings call that the regulatory process is proceeding apace. "We continue to work diligently to satisfy regulatory requests and now believe, based on our experience so far, the transaction should close in the first part of 2022," he said. "We are highly energized about the positive impact we can have working together with the exceptional Change team; a team aligned with our mission and values and focused on delivering substantial benefits for the health care system," he added. UnitedHealth Group intends to fold Change into its Optum subsidiary, which features a large data analytics arm, OptumInsight. McMahon said that the company believes the combination will allow it to address gaps in care, reduce administrative waste and allow for greater simplicity in healthcare payments. "Optum and ChangeHealthcare’s capabilities fundamentally are complementary and distinct. Because both companies already successfully serve health plans and state governments, care providers and consumers in a highly competitive market, we believe this combination will make the health care system work better for everyone, and bring exceptional value to those we serve," McMahon said.
