Tenet Healthcare Corporation is an American for-profit healthcare services company headquartered in Dallas, Texas. Its origins trace back to 1969 when attorneys Richard Eamer, Leonard Cohen, and John Bedrosian incorporated National Medical Enterprises in Los Angeles. Through decades of expansion, divestiture, and reinvention, the company became Tenet Healthcare in 1995 and has since built one of the country’s largest platforms of hospitals and ambulatory care facilities. Today it operates approximately 50 acute care hospitals, more than 535 ambulatory surgery centers and surgical hospitals, and Conifer Health Solutions, a revenue cycle management business. Tenet employed approximately 98,000 people as of year-end 2024 and reported $20.67 billion in revenue. Its stock trades on the NYSE under the ticker THC.
Key Stats
Tenet Healthcare History
Tenet Healthcare’s history spans over five decades and four distinct business identities — National Medical Enterprises, a specialty hospital era, the Tenet rebrand, and the current ambulatory-led structure. The company has been alternately one of the most aggressive acquirers and most active hospital sellers in the US healthcare industry.
-
1969Founded as National Medical Enterprises Attorneys Richard Eamer, Leonard Cohen, and John Bedrosian incorporate National Medical Enterprises (NME) in Los Angeles, California. Within months the company acquires four hospitals, launching what becomes one of the fastest-growing hospital networks in the country.
-
1975Rapid Expansion NME owns, operates, and manages 23 hospitals alongside a home health care business. The company’s growth pace accelerates through the late 1970s as the for-profit hospital sector expands rapidly under favorable Medicare reimbursement conditions.
-
1982Four Operating Groups NME restructures its business into four groups: international, hospitals, nursing homes, and medical products and services. By this point the company has grown to the point where structured divisional management becomes necessary.
-
1990Second-Largest Hospital Company NME operates approximately 200 hospitals and becomes the second-largest hospital company in the United States. The network’s concentration in specialty psychiatric and substance abuse hospitals later becomes a legal and reputational liability.
-
1994Scandal and Restructuring NME reaches a $379 million settlement with federal and state investigators over allegations of psychiatric patient admissions fraud and Medicare/Medicaid overbilling — one of the largest healthcare fraud settlements to that date. The company divests its specialty facilities and refocuses on acute care hospitals.
-
1995Renamed Tenet Healthcare NME acquires American Medical International (AMI) and changes its name to Tenet Healthcare Corporation. The new name was chosen to signal a fresh start and a commitment to a set of principles — a “tenet” — for operating the business.
-
1998USPI Founded United Surgical Partners International (USPI) is founded as an independent company to develop and operate ambulatory surgery centers and surgical hospitals. Tenet later acquires USPI, making it the foundation of its non-hospital ambulatory platform.
-
2008Conifer Health Solutions Launched Tenet launches Conifer Health Solutions from its existing patient financial services operations. The business provides revenue cycle management and healthcare support services, initially to Tenet’s own facilities and eventually to hundreds of external hospital and health system clients.
-
2013Vanguard Health Systems Acquired Tenet acquires Vanguard Health Systems for approximately $4.3 billion, including the assumption of $2.5 billion in Vanguard debt. The deal adds 28 hospitals and 39 outpatient centers across Arizona, California, Illinois, Massachusetts, Michigan, and Texas, making Tenet the third-largest investor-owned hospital company in the US.
-
2015USPI Merger Tenet merges with USPI to create one of the largest ambulatory surgery platforms in the United States. The transaction gives Tenet a majority stake in USPI with a path to full ownership, and is the pivotal strategic move that shifts the company’s growth model from hospital acquisitions toward lower-cost ambulatory care.
-
2021SurgCenter Development Acquired USPI completes the acquisition of SurgCenter Development (SCD) for approximately $1.1 billion, adding 86 ambulatory surgery centers and a pipeline for new de novo center development. The deal, following an earlier SCD transaction in 2020, is the largest single expansion of USPI’s ambulatory footprint.
-
2024Hospital Divestiture Wave Tenet completes the sale of 14 hospitals during 2024, selling facilities to systems including UCI Health, Adventist Health, and Novant Health, among others. CEO Saum Sutaria describes the year as one of “portfolio transformation” that reduces hospital count to around 50 while driving balance sheet deleveraging and earnings growth.
Tenet Healthcare Co-founders
Richard Eamer
An attorney by training, Eamer co-founded National Medical Enterprises in 1969 and served as the company’s chairman and CEO for over two decades. Under his leadership, NME grew from four hospitals to one of the largest hospital networks in the United States. He stepped down in the early 1990s as the company confronted federal investigations into its specialty hospital practices.
Leonard Cohen & John Bedrosian
Cohen and Bedrosian co-founded National Medical Enterprises alongside Eamer in 1969. Both were attorneys who saw the opportunity to bring corporate management discipline to the fragmented hospital market. They helped structure the company’s early financing, acquisitions, and governance framework as NME built its initial network across California and beyond.
Tenet Healthcare Revenue
Tenet’s revenue grew sharply after the 2013 Vanguard acquisition and the 2015 USPI merger, peaking at around $19.6 billion in 2016. Revenue declined through 2018 and 2019 as the company sold hospitals to reduce debt and focus on higher-margin markets. Recovery came in 2021 as ambulatory volumes rebounded post-COVID, and revenue has continued growing, reaching $20.67 billion in 2024 despite the ongoing hospital divestiture program.
Tenet Healthcare Market Cap
Tenet’s market cap has been volatile, reflecting the company’s high debt load and the cyclicality of US hospital utilization. It bottomed below $3 billion in 2019 before recovering strongly. The 2024 hospital divestiture program — which generated substantial cash for debt reduction — drove a significant re-rating; by early 2026 Tenet’s market cap had reached approximately $20 billion, well above its range for most of the prior decade.
Tenet Healthcare Acquisitions
Tenet has spent its history alternating between aggressive acquisition phases and disciplined divestiture periods. The pattern has repeated twice — a build-up in the 1980s, a sell-off in the 1990s, a second build-up from 2013 to 2015, and a second round of hospital sales from 2016 through 2024.
The most transformative acquisition was the 2013 Vanguard Health Systems deal at $4.3 billion. Vanguard added 28 hospitals in markets including Detroit, Phoenix, Chicago, and San Antonio — many cities where Tenet had no previous presence. The deal nearly doubled the hospital count overnight but also added significant debt that weighed on the stock for years afterward.
The 2015 merger with USPI was equally consequential, though structured differently. Rather than a cash-funded hospital purchase, the USPI transaction gave Tenet a majority stake in an ambulatory platform with a built-in growth engine. USPI’s model — partnering with health systems and physician groups to develop and operate surgery centers — proved more durable than hospital ownership, generating higher margins with lower capital intensity.
The 2020 and 2021 SurgCenter Development acquisitions built USPI into the largest ambulatory surgery operator in the United States. The two transactions added more than 100 surgery centers and a pipeline for future development, fundamentally shifting the balance of Tenet’s revenue mix toward ambulatory care.
On the divestiture side, Tenet sold hospitals throughout 2016 to 2019 to reduce debt accumulated from Vanguard, and then accelerated that process in 2024. The hospital sales to UCI Health, Adventist Health, and Novant Health were part of a deliberate strategy to concentrate the hospital portfolio in markets where Tenet holds strong competitive positions, while using proceeds to pay down leverage and invest in USPI growth.
Tenet Healthcare Competitors
In hospital operations, Tenet’s closest rivals are HCA Healthcare — the largest for-profit hospital company — Community Health Systems, and Universal Health Services. In ambulatory surgery, USPI competes with Surgery Partners and SCA Health, as well as with the ASC divisions of several large non-profit health systems.
