TPG (NASDAQ: TPG), a global alternative asset management firm, and AmerisourceBergen Corporation (NYSE: ABC) today announced that they have agreed to acquire OneOncology, a network of leading oncology practices, from General Atlantic, a leading global growth equity firm. TPG has agreed to acquire a majority interest in OneOncology, and AmerisourceBergen will acquire a minority interest in the company. OneOncology’s affiliated practices, physicians, and management team will also retain a minority interest in the company. The transaction values OneOncology at $2.1 billion.

“OneOncology has been focused on strengthening independent oncology practices by helping them grow and deliver high-value cancer services, and General Atlantic’s involvement and investment have been central to our success,” said Dr. Jeff Patton, Chief Executive Officer of OneOncology. “As we look ahead, we are excited to continue building the platform in partnership with TPG, a proven investor in the healthcare provider space, and AmerisourceBergen, a healthcare leader with significant capabilities and solutions for community oncology practices.”

“OneOncology’s physician leadership and partnership model provide access to the latest clinical pathways, research, and technology to deliver personalized care with market-leading patient outcomes and experiences. The company is enabling high-quality and efficient cancer care by empowering leading practices and physicians to remain independent while providing benefits of scale that create value for the entire healthcare ecosystem,” said Kendall Garrison, Partner at TPG. “We believe that lower cost, higher quality models represent the future of care delivery, and we are proud to partner with Dr. Patton and the OneOncology team as well as AmerisourceBergen to invest behind accessible, best-in-class clinical care,” said John Schilling, Partner at TPG.

“The investment in OneOncology will allow AmerisourceBergen to further deepen our relationships with community oncologists and expand on our solutions in specialty,” said Steven H. Collis, Chairman, President & Chief Executive Officer of AmerisourceBergen. “As a platform built by and for community oncologists, OneOncology understands the operational complexities oncologists face and works to simplify the provider experience to drive improved patient outcomes. We are excited to work closely with OneOncology’s team and our partners at TPG, who have deep experience and a track record of success in supporting high-quality healthcare companies. Our complementary skill sets and focus on operational excellence and innovation uniquely position us to continue to partner and support OneOncology’s network. We look forward to discussing the transaction in greater detail on our earnings call on May 2, when we will also discuss the continued strength of our business.”

“Our 2018 investment in OneOncology helped launch a shared vision to improve the future of cancer care amidst prevailing cost, quality and access issues,” said Justin Sunshine, Managing Director at General Atlantic. “We are proud that this mission-driven approach has resulted in a leading oncology platform that empowers high-quality and innovative cancer care in the community setting. We wish Dr. Patton and the OneOncology team continued success in their next phase of growth.”

TPG is investing in OneOncology through its U.S. and European late-stage private equity platform, TPG Capital. TPG Capital has a long history of partnering with leading management teams to invest behind healthcare providers and services that are enhancing and transforming how healthcare is delivered for the benefit of patients and the broader healthcare community, including Kelsey-Seybold Clinic, a leading value-based multi-specialty physician group in Greater Houston, Kindred at Home, one of the largest home health and hospice providers in the U.S., and Monogram Health, a value-based specialty provider of in-home evidence-based care and benefit management services for patients living with chronic kidney disease and end-stage renal disease.

Broadens AmerisourceBergen’s Reach in Key Area of Focus and Advances the Company’s Long-Term Vision

The proposed transaction will build on AmerisourceBergen’s key strategic imperatives and areas of focus by:

  • Deepening relationships with a leading network of community oncology practices. OneOncology is one of the largest and fastest growing community oncology practice management platforms in the United States with over 900 affiliated providers across 14 states. Adding this leading network builds on AmerisourceBergen’s strong ties to community healthcare providers.
  • Expanding solutions for community oncology practices. AmerisourceBergen is focused on developing technology, practice management, and data & analytics solutions to help address evolving needs and complexity for community oncology practices. OneOncology’s practice management services are complementary to AmerisourceBergen’s existing capabilities in inventory management, practice analytics and clinical trial support.
  • Investing in a commercial and strategic strength – Specialty. AmerisourceBergen’s legacy of strength and solutions in Specialty, oncology in particular, have been important drivers of its historical growth and will continue to contribute to its long-term growth. This strategic investment further enhances AmerisourceBergen’s oncology platform.

Transaction Overview
TPG, AmerisourceBergen, and OneOncology’s affiliated practices, physicians, and management team will form a new joint venture that will acquire OneOncology from its existing shareholders, including current majority owner General Atlantic. AmerisourceBergen will purchase its minority interest in the joint venture for approximately $685 million in cash, which will represent approximately 35% ownership in the joint venture.

Beginning on the third anniversary of the closing of the joint venture’s acquisition of OneOncology and ending on the day before the fourth anniversary of that closing, TPG will have a put option under which TPG may require AmerisourceBergen to purchase all of the other interests in the joint venture, including TPG’s interest, at a price equal to 19 times OneOncology’s adjusted earnings before interest, taxes, depreciation and amortization (EBITDA) for the most recently ended 12-month period prior to TPG’s exercise of the put option, all of which is subject to various other adjustments and qualifications. In addition, on the date that is the third anniversary of the closing and again beginning on the fourth anniversary of the closing and ending on the day before the fifth anniversary of the closing, AmerisourceBergen will have a call option to purchase all of the other interests in the joint venture, including TPG’s, also at the price set forth above subject to various other adjustments and qualifications.

The transaction is expected to close by the end of September 2023 and is subject to the satisfaction of customary closing conditions, including receipt of required regulatory approvals.

AmerisourceBergen Accounting Summary
Upon closing, the minority interest in OneOncology is expected to contribute a few cents to AmerisourceBergen’s adjusted diluted EPS in the first 12 months following closing.
