Muddy Waters concludes that ENSG engages in a systematic scheme at an estimated ~20 of its 379 Skilled Nursing Facilities to rent the licenses of Administrators who are not generally present at, nor actually managing, the facilities. This scheme — which could amount to fraud against states, Medicare, and Medicaid — is the pillar upon which ENSG's acquisition strategy and margins are built. Federal law requires each SNF have a licensed Administrator to be eligible to bill Medicare and Medicaid (69% of revenue). Under the False Claims Act, violations could lead to theoretical sanctions of ~$7 billion. Compliance alone would reduce 2027 EBIT by ~35% vs consensus.

The Core Allegation
ENSG engages in a systematic scheme at an estimated ~20 of its 379 Skilled Nursing Facilities (SNFs) to rent the licenses of Administrators who are not generally present at, nor actually managing, the facilities.
Ensign enters into consulting agreements with these nominal Administrators that appear to cause Ensign to state the facilities have licensed Administrators — when in fact these administrators are seldom on premise and do not substantively manage the facilities.
Why This Is Fraud
Federal law requires each SNF have a licensed Administrator (the state sets the licensing requirement) who manages the facility to meet a Condition of Participation to be eligible to bill Medicare and Medicaid, which account for 69% of ENSG's revenue.
The Administrator is legally responsible for:
- Facility operations
- Staffing
- Regulatory compliance
- Resident safety
- Quality of care
Muddy Waters estimates that ~20% of ENSG's facilities operate without a licensed Administrator supervising them.
The False Claims Act Exposure
Under the False Claims Act, if these practices have been in place for one year at ~20% of facilities, the violations could lead to theoretical sanctions of ~$7 billion.
The Financial Impact
Without the license renting scheme and related practices:
- EBITDAR margins would compress by ~210 bps
- Growth would be limited to the ~2% rate of its peers
- 2027 EBIT would be reduced by ~35% vs consensus (exclusive of any sanctions)
The Investigation
Muddy Waters sent investigators to 57 of Ensign's 379 facilities across eight states. They found red flags consistent with rented licenses at 12 of these facilities (21%).
- MW obtained a "Consulting Agreement" reportedly used to rent an Administrator's license
- Nine former employees detailed how the scheme operates — making clear the practices are intended to deceive regulators
- CMS appears unaware of the systematic behavior, likely due to the numerous brands under which ENSG operates
- In 2023 and 2024, CMS issued reports showing unlicensed operators running four facilities that belong to ENSG — but has not yet connected the dots
Expert Validation
A former DOJ prosecutor and former OIG special agent emphasized the gravity of this apparent conduct, noting that:
- The conduct likely amounts to fraud, particularly if there's evidence of concealment
- These are not minor paperwork violations
- Enforcement is more likely when misconduct involves a vulnerable patient population and a licensing requirement intended to protect health and safety
