Stonepeak-backed Akumin, a provider of freestanding outpatient radiology services, agreed to acquire Alliance Healthcare Services, a provider of radiology and oncology solutions to hospitals, health systems and physician groups, from Tahoe Investment Group, a real estate development company, for $820m. "We have always said Akumin’s vision is to drive patient-centered innovation, service delivery standardization, and exceptional healthcare value, all in an outpatient care setting. The acquisition of Alliance is transformative in a changing healthcare ecosystem that continues to shift toward outpatient, price-transparent, value-based care. There’s no other organization that has the complement of attributes we will offer together as outpatient healthcare services experts, in particular with Alliance’s longstanding hospital and health system relationships and Akumin’s freestanding operational expertise," Riadh Zine, Akumin President and CEO.
