Quick answer
Private equity due diligence is the financial, legal, operational and commercial review a sponsor runs on a target before closing.
It rarely checks a target’s prior ownership and transaction history. Sale-leasebacks, dividend recapitalizations and past sponsor conduct sit in the public record instead, and a growing number of state healthcare laws now put that record inside the closing timeline.
Key takeaways
Private equity due diligence is the investigation a sponsor runs on a target company before it commits capital. The due diligence process confirms the numbers in the confidential information memorandum, tests the investment thesis and surfaces risk before the deal closes.
Most of what a deal team learns during private equity due diligence comes from the target itself: management interviews, financial statements, contracts and the data room the seller assembles. The seller controls what goes into that data room. A target has no legal obligation to volunteer how a previous owner structured an earlier deal, even when that structure explains the company’s current financial condition.
A standard private equity due diligence process runs across eight workstreams. Each answers a different question about the target, and each draws on a different part of the data room.
| Workstream | What it checks | Usual source |
|---|---|---|
| Financial | Revenue quality, margins, working capital, debt | Audited statements, management accounts |
| Commercial | Market position, customer concentration, pipeline | Customer interviews, market data |
| Legal | Contracts, litigation, ownership rights | Corporate records, disclosed filings |
| Operational | Systems, supply chain, process maturity | Site visits, process documentation |
| Tax | Exposure, structuring, transfer pricing | Tax returns, advisor memos |
| IT | Systems, security, data ownership | IT documentation, vendor contracts |
| HR and management | Leadership depth, retention, incentive design | Management interviews, HR records |
| ESG | Environmental, social and governance exposure | Policies, disclosures, site data |
For a workstream-by-workstream breakdown with red flags and a post-close action plan, see the private equity due diligence checklist. What that checklist and most private equity due diligence processes do not include is a systematic check of who owned the target before, and what that owner did to it.
The eight workstreams above answer whether the target’s current numbers are real. They do not answer a different question: what happened to this company under its last owner, and does that history change what the numbers mean.
Sale-leaseback history
A prior owner sold the target’s real estate and leased it back, often at rent the operating business cannot sustain over the full lease term.
Dividend recapitalization history
A prior owner raised debt against the company specifically to fund a payout to itself, adding leverage without adding operating value.
Beneficial ownership and sanctions exposure
Complex holding structures can obscure who actually controls the target, including ultimate beneficial owners with undisclosed sanctions or litigation history.
Adverse regulatory findings
FDA warning letters, Joint Commission citations or CMS quality findings that a confidential information memorandum has no obligation to surface.
Two documented healthcare cases show why ownership and transaction history matters to private equity due diligence. Both are matters of public record, not internal company data.
| Case | Structure | Outcome |
|---|---|---|
| Steward Health Care, owned by Cerberus Capital Management | 2016 sale-leaseback moved $1.25 billion of hospital real estate to Medical Properties Trust [6] | Chapter 11 bankruptcy filed May 6, 2024, followed by hospital closures [1] |
| Prospect Medical Holdings, owned by Leonard Green & Partners, 2010 to 2021 | Debt-funded dividends and preferred stock redemption totaling $645 million | $424 million went to Leonard Green investors before Prospect’s 2025 bankruptcy filing [2] |
The Senate Budget Committee’s bipartisan January 2025 report, based on more than a million pages of subpoenaed documents, examined Leonard Green & Partners’ ownership of Prospect and Apollo Global Management’s ownership of Lifepoint Health, and concluded that both sponsors’ financial decisions worsened patient care while extracting outsized returns. [2] Steward’s collapse is documented separately, through securities filings and Massachusetts’s own account of the “loopholes” the state closed in response. [7] Both patterns, real estate stripping and dividend recapitalization, sit in filings and reports a current seller has no duty to hand a buyer during private equity due diligence.
The 2010s brought a separate reckoning for records like these. The Pandora Papers showed how much ownership history sits outside any single company’s filings, spread across corporate registries, court records and financial disclosures in different jurisdictions.

A scoped call maps the target’s beneficial ownership, prior sponsors and sale-leaseback or dividend recap history, with findings returned as a board-ready written report.
Ownership history used to be a diligence choice. In healthcare deals, it is becoming a closing-timeline requirement.
| Law | Requirement | Penalty for non-compliance |
|---|---|---|
| California AB 1415, effective January 1, 2026 | 90 days’ written notice to the Office of Health Care Affordability before closing a material transaction [3] | Transaction cannot close until notice and any review is resolved |
| Massachusetts H.5159, signed January 8, 2025 | Discloses equity investors, REITs, MSOs and sale-leaseback arrangements in annual financial reporting [4] | Up to $25,000 per week of delay, with no annual cap [4] |
At least 11 states have enacted laws specifically expanding oversight of private equity healthcare transactions since 2024, and a broader group of roughly 25 states have proposed or passed some form of healthcare transaction notification requirement, according to state policy tracking cited by Medscape. [5] A deal team running private equity due diligence on a healthcare target now needs to check which of these regimes apply before setting a closing date, not after signing.
Once a transaction sits inside a mandatory notice window, a target’s ownership and transaction history is exactly what a regulator, or a competing bidder, has time to find. Private equity due diligence that has not traced that history before filing is running the same search a regulator will, just later.
Scope the ownership question before the data room opens
Define what needs tracing: beneficial ownership, prior sponsors, name changes and any real estate or capital structure history tied to the target.
Search corporate records and court records, not just the CIM
Corporate registries, court filings and prior transaction records show ownership changes a confidential information memorandum will not mention.
Add open source intelligence to trace names, roles and past conduct
Analyst-led OSINT-powered due diligence connects founders and executives to prior litigation, regulatory action or media coverage that standard background checks miss.
Fold findings into enhanced due diligence, not a side memo
Ownership and transaction history findings belong in the same investment committee memo as financial and commercial diligence, with the same level of evidence.
Check the notice window before the deal team sets a closing date
Confirm whether AB 1415, a state material-change law or another notification regime applies, and build the review period into the timeline before signing.
Most deal teams can describe their financial diligence process step by step. Fewer can answer these questions about the same target with the same confidence.
Who owned this target before
Not just the current cap table. Every owner back to formation, and what each one did with the balance sheet.
Was the real estate ever separated from the operating business
A sale-leaseback years ago can still be setting the rent the target pays today.
Has the target or its holding company changed names
Name changes can separate a company from its own regulatory or litigation history in a standard search.
Does a state notice window apply to this deal
If the target operates in a state with a material-change law, the closing timeline may already be longer than the deal model assumes.
