Fortress Value Acquisition Corp. II (NYSE: FAII), a special purpose acquisition company, and ATI Physical Therapy, a portfolio company of Advent International and the largest single-branded outpatient physical therapy provider in the United States, announced today that they have entered into a definitive merger agreement. Upon closing of the transaction, the combined company will operate as "ATI Physical Therapy, Inc." and remain NYSE-listed under a new ticker symbol. The transaction is expected to close in the second quarter of this year, subject to approval by FVAC II's stockholders and other customary closing conditions.

ATI owns and operates nearly 900 physical therapy clinics across 25 states. The Company operates its business based on data and analytics, augmented by a relentless focus on delivering superior patient outcomes that exceed industry benchmarks and service excellence to its patient, provider and payor customers.

The existing management team, led by CEO Labeed Diab, CFO Joe Jordan and COO Ray Wahl, will continue to lead the business, and Advent will remain ATI's largest stockholder.

A Record of Growth in an Evolving Industry

ATI operates in the growing outpatient physical therapy segment of the musculoskeletal ("MSK") treatment industry, which represents an estimated $22 billion market, within a broader MSK treatment industry representing $300-$400 billion in total spend.1 Multiple secular tailwinds are driving increased demand for outpatient physical therapy services, including: favorable demographic trends, specifically the rise in individuals over the age of 65; greater desire for active lifestyles throughout life; and continued shift towards outpatient care. In addition, there is an increasing shift away from invasive and cost inefficient treatment modalities such as surgeries and opioids to physical therapy as an effective first line of treatment for many MSK conditions.

The combination of a fast-growing market and transition to value-based healthcare has allowed ATI to execute a strategy of organic growth, accretive acquisitions and market-leading profitability in a highly fragmented industry. Since 2016, ATI has opened approximately 300 new clinics and acquired and integrated approximately 125 clinics. And with its EMR database of 2.5+ million patient cases, the Company believes it is uniquely equipped to not only deliver consistent, high-quality patient outcomes but also intelligently design and capitalize on value-based healthcare risk sharing arrangements.

"I am extremely proud of our team and the leadership role ATI plays across the nation in consistently delivering exceptional musculoskeletal outcomes, driving efficiencies and cost savings that benefit the healthcare ecosystem and delivering great results for our patients, providers and payors," said Labeed Diab, CEO of ATI. "We expect to remain an active participant in the evolution of the industry and look forward to this next, exciting phase of our growth."

Drew McKnight, CEO of FVAC II, commented, "We have followed ATI for a long time, having been an investor in the credit for over ten years. Since Advent bought the business in 2016, we've watched and admired the company's growth, in particular their approximately 300 new clinics through their de novo growth effort. With this strong leadership team and strong balance sheet, we believe ATI is well positioned to continue this de novo growth as well as be a primary and preferred acquirer in what is still a fragmented industry."

John Maldonado, a Managing Partner at Advent, said, "We are proud of what we have achieved in our partnership with ATI. Together, we strengthened ATI's industry leadership through a focus on outcomes and value-based care initiatives that have further differentiated the Company's physical therapy offering. Our tech and operational investments have enabled ATI to grow its clinic footprint by 50 percent while consistently putting patient care first and further enhancing its clinician-centric culture. We look forward to working more closely with Fortress in supporting ATI's continued growth."
