LBO vs. Growth Equity: Key Differences for Interview Prep

LBO and growth equity are the two dominant strategies in private equity, and interviewers at both buyout and growth equity firms frequently ask candidates to explain the differences. The models look similar on the surface (entry valuation, hold period, exit), but the investment thesis, capital structure, return drivers, and risk profiles are fundamentally different. This guide covers both strategies side by side with the comparison framework interviewers expect.

The core distinction

LBO (Leveraged Buyout): Acquire a mature, cash-generative business using significant debt. Returns driven by deleveraging, EBITDA growth, and multiple expansion. The business pays for itself.

Growth Equity: Invest minority (or majority) equity in a high-growth company that needs capital to scale. Little or no debt. Returns driven by revenue/EBITDA growth and multiple expansion. The business needs capital to reach its potential.

LBO: "This business generates enough cash to support debt and pay it down."
Growth Equity: "This business needs our capital to grow faster than it could alone."

Side-by-side comparison

LBO model structure (review)

Entry EV = EBITDA × Entry Multiple (typically 8x-12x)
Debt = 4.0-6.0x EBITDA (55%-65% of EV)
Equity = EV − Debt (the plug)

Hold: debt paydown from cash flow + EBITDA growth + potential multiple expansion
Exit: Exit EV − Remaining Debt = Exit Equity
Returns: MoIC and IRR on equity invested

Key LBO characteristics tested in interviews:

• Sources & uses with debt sized first, equity as plug
• Debt schedule with cash sweep
• Returns attribution (deleveraging vs. growth vs. multiple expansion)
• LBO candidate screening (cash flow, low capex, defensible market)

Growth equity model structure

Entry Valuation = Revenue × Revenue Multiple (or EBITDA × EBITDA Multiple if profitable)
Investment = Minority stake (e.g., 20% ownership for $50M)
No debt (or minimal venture debt)

Hold: revenue scales, margins expand, company reaches profitability
Exit: Exit Revenue × Exit Multiple (or Exit EBITDA × Exit EBITDA Multiple)
Returns: MoIC and IRR on equity invested (no deleveraging component)

Key growth equity characteristics:

Revenue-based valuation

Many growth equity investments are valued on revenue multiples because the company isn't profitable yet:

SaaS example:
  Entry: $20M revenue × 8x = $160M EV
  Investment: $40M for 25% stake
  Exit (Year 5): $80M revenue × 6x = $480M EV
  Exit value of stake: $480M × 25% = $120M
  MoIC: $120M ÷ $40M = 3.0x

No deleveraging return driver

Without debt, there's no deleveraging component. Returns come entirely from:

1. Revenue growth (the primary driver)
2. Margin expansion (operating leverage as the company scales)
3. Multiple expansion or compression (market sentiment at exit)

Minority protections

Growth equity investors typically negotiate:

• Board seat or observer rights
• Information rights
• Pro-rata participation in future rounds
• Anti-dilution protection
• Liquidation preference (1x non-participating typical)

These aren't modeled in a simple returns build but matter for investment structure discussions in interviews.

When each strategy applies

LBO candidates

• Mature, profitable businesses with predictable cash flow
• Low capex relative to EBITDA
• Defensible market position
• Headroom for operational improvement
• Debt capacity (4.0x+ EBITDA leverage supportable)

Examples: industrial services, business services, consumer staples, healthcare services, software with recurring revenue and high margins.

Growth equity candidates

• High-revenue-growth businesses (30%+ annually)
• Large addressable market with room to capture share
• Proven product-market fit (not pre-revenue)
• Capital needed for sales/marketing scale, geographic expansion, or product development
• Path to profitability visible (even if not yet profitable)

Examples: SaaS, fintech, healthcare IT, e-commerce, consumer brands scaling nationally.

Return comparison: worked example

Same company, two approaches:

Company: $50M revenue, $10M EBITDA, growing 25%/year

LBO approach (8x EBITDA entry, 5x leverage, 5-year hold):

• Entry EV: $80M; Debt: $50M; Equity: $30M
• Exit EBITDA: $30.5M (25% CAGR); Exit at 8x = $244M EV
• Exit debt (paid down): $10M; Exit equity: $234M
• MoIC: 7.8x; IRR: ~50% (but requires execution on debt paydown + growth)

Growth equity approach (6x revenue entry, no debt, 20% stake, 5-year hold):

• Entry valuation: $300M; Investment: $60M for 20%
• Exit revenue: $152M; Exit at 5x = $762M EV
• Exit value of stake: $152M
• MoIC: 2.5x; IRR: ~20%

The LBO produces higher returns if the company can support leverage and grow, but the risk is higher (debt service, covenant breach). Growth equity produces lower returns but with less downside risk (no debt, minority stake, diversification across portfolio).

What interviewers ask

"What's the difference between LBO and growth equity?" LBO: mature company, significant debt, returns from deleveraging + growth + multiple expansion. Growth equity: high-growth company, minimal debt, returns from revenue scaling + margin expansion. Different risk profiles and return drivers.

"Can you LBO a high-growth company?" Difficult, since high-growth companies often have negative or thin free cash flow, making debt service challenging. Some growth companies transition to LBO candidates as they mature and generate cash. The "graduation" from growth equity to LBO is a common path.

"Which has higher returns?" Growth equity targets higher IRRs (25%-35%+) because of the growth premium, but on a per-deal basis, successful LBOs can produce higher MoIC (3x-5x) through leverage amplification. Portfolio-level returns depend on hit rate and loss ratio.

"Which is riskier?" Different types of risk. LBO: financial risk (leverage, covenants, debt service). Growth equity: execution risk (growth stalls, competition, market shifts). LBO downside is losing equity to debt; growth equity downside is dilution or write-down.

"How would you model a growth equity investment?" Revenue projection → margin expansion → exit valuation (revenue or EBITDA multiple) → returns on equity invested. No debt schedule, no deleveraging. Focus on revenue growth assumptions and exit multiple justification.

Prep implications

If you're interviewing at a buyout fund: master LBO mechanics, returns attribution, paper LBO, QoE, and buy-and-build. Know growth equity conceptually but don't deep-dive.

If you're interviewing at a growth equity fund: master revenue-based valuation, growth modeling, unit economics (CAC, LTV, churn for SaaS), and market sizing. Know LBO basics but focus on growth drivers.

If you're interviewing at a multi-strategy fund (Blackstone, KKR, Carlyle): know both deeply and be ready to compare.

The takeaway

LBO and growth equity are different strategies for different companies at different stages. The interview skill is articulating why a specific company fits one strategy and not the other, and building the right model for each. Buyout candidates who can explain growth equity (and vice versa) demonstrate breadth that single-strategy candidates lack. Know both frameworks, go deep on the one that matches your target firm, and always connect the strategy to the company's characteristics.
