How to evaluate a private markets deal: the GP-led due diligence framework

The institutional vs retail divide in private markets due diligence

When TPG structured its $1.8 billion continuation vehicle for Inclusive Capital Partners in 2023, institutional LPs spent six months dissecting operator incentives, portfolio company governance structures, and exit optionality. Retail investors in similar deals often focus primarily on historical returns and marketing materials. This fundamental difference in approach explains why sophisticated investors consistently achieve better risk-adjusted returns in private markets.

Institutional investors deploy systematic frameworks that examine structural elements beyond surface-level metrics. They understand that private markets investing is fundamentally about information asymmetry, alignment of interests, and operational execution over multi-year horizons.

Layer 1: Asset quality and valuation methodology

Portfolio composition analysis
Start by mapping the underlying assets against market fundamentals. When Blackstone's BREIT faced redemption pressures in late 2022, sophisticated investors who had analyzed the portfolio's concentration in Sun Belt multifamily properties were better positioned to assess downside scenarios.

Key evaluation points:

• Geographic and sector diversification: Does concentration risk match the premium being charged?
• Asset maturity stages: Are you investing in proven cash-flowing assets or development projects with execution risk?
• Competitive positioning: How defensible are the underlying business models or property locations?

Valuation methodology scrutiny
Private markets valuations often rely on comparable company analysis, discounted cash flow models, or net asset value approaches. The methodology matters more than the headline multiple.

Critical questions:

• What discount rates are being applied and how do they compare to current market conditions?
• Are comparable companies truly comparable in terms of growth profile, margins, and market position?
• How frequently are valuations updated and by whom?

When WeWork's valuation collapsed from $47 billion to under $10 billion, investors who had questioned the revenue multiple methodology and unit economics early avoided massive losses.

Layer 2: Operator track record and alignment of interests

Track record beyond headline returns
Net IRR figures tell an incomplete story. Dig into the components: realized vs unrealized gains, timing of cash flows, and performance across different market cycles.

Apply the "full cycle analysis" framework:

• How many complete investment cycles has the GP managed?
• What percentage of historical returns came from multiple expansion vs operational improvements?
• How did the GP perform during the 2008-2009 crisis, COVID-19 disruption, or recent interest rate volatility?

Skin in the game assessment
General partners should have meaningful personal capital invested alongside LPs. Apollo's co-founders have committed over $2 billion of personal wealth to their funds, creating genuine alignment.

Evaluate:

• GP commitment as percentage of fund size
• Whether GP commitment is invested pari passu with LPs
• Clawback provisions and their enforceability

Layer 3: Legal structure and investor protections

Governance rights and information access
Private markets investments often involve long lock-up periods. Your legal protections during this time are critical.

Essential provisions:

• Advisory committee representation: Do LPs have meaningful input on key decisions?
• Reporting requirements: Quarterly financial statements, annual audits, and portfolio company updates
• Transfer rights: Can you sell your interest in secondary markets?

Conflict of interest management
GPs often manage multiple funds or have other business interests. When KKR invested in both Nielsen and IRI (competing market research firms) across different funds, LPs needed clear conflict management protocols.

Red flags include:

• Co-investment opportunities systematically allocated to GP affiliates
• Related party transactions without independent oversight
• Fee arrangements that change based on fund performance

Layer 4: Exit pathway and timeline realism

Market timing and liquidity analysis
Private markets exits depend heavily on market conditions and timing. The IPO market for technology companies remained essentially closed throughout 2022-2023, forcing GPs to extend hold periods or accept lower valuations in trade sales.

Assess exit optionality:

• Strategic buyer universe: How many logical acquirers exist for the underlying assets?
• IPO readiness: Do portfolio companies meet public market size and growth requirements?
• Secondary market depth: Is there an active market for the asset class?

Timeline realism
Be skeptical of aggressive exit timelines, especially for complex assets. Real estate development projects routinely take 2-3 years longer than initial projections due to permitting, construction, and market delays.

Layer 5: Fee structure and carry economics

Total cost of ownership
Private markets fees extend beyond management fees and carried interest. Calculate the all-in cost including:

• Management fees (typically 1.5-2.5% annually)
• Carried interest (usually 20%, but with varying hurdle rates)
• Transaction fees and monitoring fees
• Portfolio company-level costs

When all fees are included, total costs often exceed 3-4% annually, significantly impacting net returns.

Carry structure analysis
Not all carry structures are created equal. European-style catch-up provisions can result in GPs receiving disproportionate economics early in the waterfall.

Prefer structures with:

• Hard hurdle rates (8%+ preferred return to LPs)
• Deal-by-deal carry with clawback provisions
• Transparent fee offset policies

Deal-killing red flags

Certain issues should result in immediate rejection:

• Regulatory or compliance issues: Any history of SEC violations or regulatory sanctions
• Key person departures: Recent exodus of senior investment professionals
• Concentration risk: >20% of assets in a single investment or related party transactions
• Liquidity mismatches: Promising quarterly liquidity on illiquid assets
• Unrealistic projections: IRR projections >25% without corresponding risk levels

Essential GP questions before commitment

Before committing capital, ask these specific questions:

1. "What was your worst investment in the last fund and why?" - Tests honesty and learning capability
2. "How do you source deals that others don't see?" - Evaluates competitive advantages
3. "What happens if interest rates rise another 200 basis points?" - Stress tests assumptions
4. "Can you provide references from LPs in your previous funds?" - Validates track record claims

Reading investment memos effectively

Focus on assumptions, not projections
Investment memos typically lead with attractive return projections. Instead, focus on the underlying assumptions:

• Market growth rates compared to historical averages
• Margin expansion assumptions and their drivers
• Exit multiple assumptions relative to current market conditions

Look for what's not included
Sophisticated memos acknowledge risks and challenges. Be wary of presentations that don't address:

• Competitive threats or market saturation
• Regulatory or environmental risks
• Key person dependencies

Verify third-party data
Many memos cite market research or industry reports. Cross-reference these sources and check publication dates. Outdated market data can significantly skew investment thesis validity.

Start your next private markets evaluation by requesting the investment memo and legal documents simultaneously. This parallel review will reveal inconsistencies between marketing materials and actual deal terms, giving you crucial negotiation leverage before commitment.
