Qwen3 Max Thinking's response to the 'Mini LBO Underwrite' challenge.
You are underwriting a 5-year LBO for a private equity investment committee. Company (fictional): HarborTech Services (HTS) – mission-critical HVAC maintenance + monitoring for data centers (mostly recurring service contracts). Use only the information below. Do NOT browse the web. This is a fictional exercise. ENTRY (close at end of FY2025) - FY2025 revenue: $900m - FY2025 EBITDA: $120m (13.3% margin) - Purchase price: 12.0x EBITDA - Transaction fees: 2.0% of enterprise value (paid at close, funded by equity) SOURCES & USES (simplified) - Total leverage at close: 5.5x EBITDA - Term Loan: 4.0x EBITDA, 9.0% cash interest, 1.0% annual amortization - Mezzanine: 1.5x EBITDA, 12.0% cash interest + 2.0% PIK (PIK accrues to principal) - Equity funds the remainder - Assume starting cash is $0. - Assume all free cash flow after required payments is used for optional Term Loan paydown (no dividends). OPERATING ASSUMPTIONS (FY2026–FY2030) Base case: - Revenue growth: 8%, 7%, 6%, 5%, 5% - EBITDA margin: 14.0%, 15.0%, 16.0%, 16.5%, 17.0% - Capex: 3.0% of revenue - Change in NWC: 0.5% of incremental revenue (cash outflow) - Cash tax rate: 25% applied to max(0, EBITDA - cash interest) (simplified) EXIT (end of FY2030) - Exit multiple: 10.5x FY2030 EBITDA - Exit fees: 1.0% of enterprise value - Mezzanine (including PIK) is repaid at exit. TASK 1) Build a simplified year-by-year table (FY2026–FY2030) with: revenue, EBITDA, cash interest (by tranche), cash taxes, capex, ΔNWC, free cash flow after debt service, and ending debt balances (Term Loan + Mezz). 2) Compute equity IRR and MOIC. 3) Provide a sensitivity table of equity IRR vs exit multiple (9.5x / 10.5x / 11.5x) and exit-year EBITDA margin (16% / 17% / 18%). 4) List 5 underwriting risks and 5 concrete downside protection levers. Keep it concise, but show the math clearly.
All FCF after mandatory payments applied to optional Term Loan paydown. Mezz PIK compounds annually. Starting cash = $0.
| FY | Rev | EBITDA | TL Cash Int | Mezz Cash Int | Cash Taxes | Capex | ΔNWC | FCF After Debt Service* | Ending TL | Ending Mezz |
|---|---|---|---|---|---|---|---|---|---|---|
| 2026 | 972.0 | 136.1 | 43.2 | 21.6 | 17.8 | 29.2 | 0.4 | 19.1 | 456.0 | 183.6 |
| 2027 | 1,040.0 | 156.0 | 41.0 | 22.0 | 23.2 | 31.2 | 0.3 | 33.4 | 417.9 | 187.3 |
| 2028 | 1,102.4 | 176.4 | 37.6 | 22.5 | 29.1 | 33.0 | 0.3 | 49.0 | 364.1 | 191.0 |
| 2029 | 1,157.4 | 191.0 | 32.8 | 22.9 | 33.8 | 34.7 | 0.3 | 61.7 | 297.6 | 194.8 |
| 2030 | 1,215.4 | 206.6 | 26.8 | 23.4 | 39.1 | 36.5 | 0.3 | 75.8 | 217.0 | 198.7 |
*FCF After Debt Service = UFCF (EBITDA – Taxes – Capex – ΔNWC) – (Total Cash Interest + $4.8M Mandatory Amortization). Represents optional Term Loan paydown capacity.
IRR calculated from MOIC = (Exit Equity Proceeds / $808.8M)^(1/5) – 1. FY2030 EBITDA = Revenue × Margin; all other assumptions unchanged.
| Exit Multiple ↓ / FY2030 EBITDA Margin → | 16% | 17% (Base) | 18% |
|---|---|---|---|
| 9.5x | 11.7% | 13.6% | 15.4% |
| 10.5x | 14.6% | 16.5% | 18.2% |
| 11.5x | 17.3% | 19.1% | 20.9% |
Key insight: IRR is more elastic to exit multiple than margin (e.g., ±1.0x multiple swing ≈ ±2.9% IRR; ±1% margin swing ≈ ±1.8% IRR at 10.5x).
5 Critical Underwriting Risks
5 Concrete Downside Protection Levers
Note: Exit fee (1%) is intentionally low to preserve equity value; no dividend recap assumed (all FCF de-levers senior debt).
