The Sabra-Landmark Unwind Was Not a Surprise
Short answer: The Sabra-Landmark split is a behavioral health story, not a senior housing story, and operators should expect more of these unwinds over the next 24 months because founders signed triple-net leases against pro formas that never stress-tested licensure delay, payer credentialing lag, or census ramp. The fix is honest feasibility work before the lease is executed, not after.
When Landmark Recovery filed for Chapter 11 in August 2025 in the U.S. Bankruptcy Court for the Middle District of Tennessee, the trade press initially framed it as a landlord dispute. It was not. Court filings showed CEO Matt Boyle blamed Sabra Health Care REIT (Nasdaq: SBRA) for inappropriately assessing the rent owed and for the “cross-collateralization” of several facilities. The dispute involved one of the largest healthcare landlords in the country.
The April 2026 settlement put a price on the unwind. A court-approved settlement dated April 8 resolved the dispute over missed rent payments and cross-collateralization, ending a years-long partnership between the addiction treatment provider and the REIT. Public reporting on the bankruptcy also shows Sabra Healthcare Holdings III LLC was listed as Landmark’s largest unsecured creditor at over $840,000. That is the operator-versus-real-estate playbook in behavioral health, and the same pattern is running right now across PE-backed platforms in Arizona, Tennessee, and North Carolina.
The REIT is not the villain here. The villain is feasibility work that never happened.
Licensure Timing Risk Is the Single Most Ignored Variable
Here is the pattern our AHS team sees repeatedly. An operator signs a lease. Construction starts. The pro forma assumes patient one walks through the door 60 days after certificate of occupancy. Then the licensure file sits with AHCA or DCF in Florida, LARA in Michigan, or the Tennessee Department of Mental Health and Substance Abuse Services for seven, nine, sometimes 14 months. Rent is accruing the entire time. A $4.2M annual lease obligation against zero revenue will eat a Series B in under a year.
AHS was asked last year to assist an operator who had closed on a 32-bed clinically managed residential site in a southeastern state before the change-of-ownership licensure was approved. The building sat dark for 11 months. Burn ran roughly $380K per month between rent, utilities, security, and skeleton staff retention. That is $4.18M of cash incinerated before a single admission. No pro forma I have ever reviewed modeled that scenario, because the operator’s broker and the REIT’s underwriter both treated licensure as a checkbox. It is not a checkbox. It is the gating event for the entire investment thesis.
Landmark’s public timeline showed how quickly the math unravels. Reporting on the first-day declaration noted that Landmark reportedly owed roughly $1 million in rent for facilities that never opened. Empty buildings still trigger rent. Every operator underwriting a triple-net lease should burn that sentence into their pro forma.
What an Honest Pro Forma Actually Looks Like
An honest behavioral health pro forma stress-tests three things the optimistic version never does.
- Licensure delay scenarios at 90, 180, and 365 days past target, mapped against the actual state agency queue and surveyor focus areas.
- Payer credentialing lag. Commercial credentialing typically runs 60 to 120 days per major payer assuming a clean CAQH ProView profile. Anthem tends to run 90 to 120 days, Carelon Behavioral Health 60 to 120 days, Optum / UnitedHealthcare 60 to 90 days. Medicaid runway should be planned at 120 to 180 days from the date the state provider portal application is submitted. The revenue cycle vendor’s promise of 30 days is fiction.
- Ramp curves that reflect actual referral pattern development in a market where the operator has no brand, not the curves from a flagship site that took four years to build.
When our team runs feasibility for a PE sponsor evaluating a multi-site expansion, we model census ramp at roughly 40% slower than the operator’s internal projection. That is not pessimism. That is what the data shows across the 60-plus sites AHS has touched. If the deal still pencils with that haircut, it is real. If it only works on the operator’s curve, the REIT lease is going to become someone’s problem in year two.
The macro backdrop is exactly what you would expect for this pattern to repeat. Researchers publishing in Health Affairs Scholar found that behavioral health facility acquisitions grew from 32 facilities in 2010 to 1,330 in 2021, with private equity-backed acquisitions accounting for roughly 60% of that activity (1,678 of 2,806 facilities). A separate study in JAMA Psychiatry by researchers at Oregon Health & Science University, Wharton, and Yale found that PE firms own roughly 6.2% of mental health facilities and 7.1% of addiction treatment facilities nationwide, with penetration reaching approximately a quarter of all mental health facilities in Colorado, Texas, and North Carolina. Lead author Jane Zhu, M.D., put it plainly: “At this point, there is no stone left unturned by private equity investors.”
The Operational Backbone Has to Exist Before the Real Estate Does
Rapid expansion fueled by REIT capital fails for a reason that has nothing to do with capital markets. The operational backbone (clinical leadership, utilization management, billing, compliance, HR infrastructure) does not scale at the same rate as the real estate footprint. Founders can build six buildings in 18 months. They cannot build six clinical directors, six medical directors, and six fully credentialed billing operations in 18 months. Not well.
And the regulators are watching. The HHS Office of Inspector General announced on November 17, 2025 an audit of Certified Community Behavioral Health Clinics’ Medicaid reimbursement and compliance with demonstration requirements, noting that states participating in the CCBHC demonstration receive federal funds at the enhanced FMAP for qualifying expenditures and must implement standardized certification and payment structures. Separately, HHS-OIG audited Pennsylvania’s largest behavioral health managed care organization and reported that none of the 100 denied service requests sampled met all requirements for denying behavioral health service requests that required prior authorization. SIU audits from commercial payers on multi-site operators whose documentation quality dropped as they scaled are increasingly common. When that audit hits and the recoupment letter shows up for $1.8M, the REIT lease still does not care.
The response window is also compressed. Under the revised CMS 60-Day Rule effective January 1, 2025, the rule changes when an overpayment is “identified,” replacing the “reasonable diligence” standard with the False Claims Act definition of “knowingly”, meaning actual knowledge, reckless disregard, or deliberate ignorance. A new provision suspends the obligation to report and return overpayments for up to 180 days if the provider conducts a timely, good-faith investigation to determine whether related overpayments exist. Miss that math and you are looking at False Claims Act exposure on top of whatever rent problem you already had.
Stress-Test Before You Sign, Not After
The disciplined version of this looks straightforward. Before any lease is executed, an operator should commission a feasibility study that maps the licensure pathway with the actual state agency, names the surveyor focus areas, models payer credentialing timelines against real contracting data, and tests the pro forma against three downside scenarios.
Operators should validate the ASAM Criteria, 4th Edition level of care assumptions against actual market need, not against what the founder wants to build. A Level 2.5 partial hospitalization program (an outpatient level of care) in a market already saturated with PHP capacity is a different investment than the deck suggests. A residential withdrawal management site has a different licensure pathway and a different surveyor focus than a clinically managed residential program. The paperwork, the staffing ratios, and the payer contracting timeline are all different.
The market signal from the REIT side matters too. Behavioral Health Business reported that the Landmark engagement helped accelerate development and expansion through real estate deals, but also brought renewed relevance to real estate in an era of behavioral health care that increasingly deprioritizes facility-based care, especially the residential treatment Landmark Recovery provides. That is a landlord book of business being recalibrated, not a landlord exiting behavioral health.
The Sabra-Landmark situation will repeat itself across behavioral health over the next 24 months. Several PE-backed platforms are sitting on lease obligations underwritten in a different reimbursement environment. Some will restructure quietly. Some will not. The operators who survive this cycle are the ones whose leadership teams treated feasibility and pro forma discipline as non-negotiable before they signed.
Frequently asked questions
What actually happened in the Sabra Health Care REIT and Landmark Recovery dispute?
Landmark Recovery filed for Chapter 11 in August 2025 in the U.S. Bankruptcy Court for the Middle District of Tennessee. Behavioral Health Business reported that CEO Matt Boyle blamed Sabra Health Care REIT for inappropriately assessing the rent owed and for cross-collateralizing multiple Landmark entities. A court-approved settlement dated April 8, 2026 resolved the dispute and ended the years-long partnership. TheStreet’s reporting on the bankruptcy filing also documented Sabra Healthcare Holdings III LLC as the largest unsecured creditor at over $840,000.
How long should an operator budget for behavioral health payer credentialing in a pro forma?
Commercial credentialing in behavioral health typically runs 60 to 120 days per major payer, assuming a clean CAQH ProView profile. Anthem usually takes 90 to 120 days, Carelon Behavioral Health 60 to 120 days, and Optum / UnitedHealthcare roughly 60 to 90 days. Medicaid facility credentialing should be planned at 120 to 180 days from the date of the state provider portal submission. AHS recommends modeling a 150-day blended assumption with downside scenarios at 180 and 270 days, because parallel state licensure delays and CAQH attestation lapses commonly extend the real-world timeline.
Is private equity actually a major force in behavioral health acquisitions, or is that overstated?
It is not overstated. Research published in JAMA Psychiatry by Zhu and colleagues found that private equity firms own roughly 6.2% of mental health facilities and 7.1% of addiction treatment facilities nationally, with penetration reaching approximately a quarter of all mental health facilities in Colorado, Texas, and North Carolina. A separate peer-reviewed study in Health Affairs Scholar found that behavioral health facility acquisition activity grew from 32 facilities in 2010 to 1,330 in 2021, with PE-backed deals representing roughly 60% of that activity (1,678 of 2,806 facilities).
How fast does an operator have to return an identified overpayment under federal rules?
Under the revised CMS 60-Day Rule effective January 1, 2025, providers must report and return an identified Medicare or Medicaid overpayment within 60 days of identification. The rule now aligns the identification standard with the False Claims Act’s “knowingly” standard, meaning actual knowledge, reckless disregard, or deliberate ignorance. It also allows a suspension of up to 180 days when the provider is conducting a timely, good-faith investigation of related overpayments arising from the same or similar cause. Failure to comply can create False Claims Act exposure.
