LBO Modeling

name: lbo-modeling description: LBO model construction — sources & uses, debt schedules, returns

When to Activate

• User needs to build or review a leveraged buyout model
• Evaluating a PE acquisition with debt financing
• Constructing debt schedules with multiple tranches
• Calculating IRR/MOIC under various exit and leverage scenarios
• Assessing maximum purchase price a financial sponsor can pay

Core Concepts

LBO Value Creation Levers

An LBO generates returns through three mechanisms:

1. Debt paydown — free cash flow services and reduces debt, equity value grows
2. EBITDA growth — revenue growth and margin expansion increase enterprise value
3. Multiple expansion — exit at a higher multiple than entry (least reliable)

Sources & Uses

Sources (how the deal is funded):

Revolving Credit Facility (drawn at close, if any)
Term Loan A
Term Loan B
Senior Secured Notes
Mezzanine / Subordinated Debt
Sponsor Equity
Management Rollover Equity
-----------------------------
Total Sources

Uses (where the money goes):

Equity Purchase Price (share price × diluted shares, or EV - net debt)
Refinance Existing Debt
Transaction Fees (advisory, financing, legal — typically 2-4% of EV)
Financing Fees (OID, arrangement fees — amortized over debt life)
Cash to Balance Sheet (minimum operating cash)
-----------------------------
Total Uses

Sources must equal Uses. This is the fundamental balancing equation.

Debt Tranches

Leverage Metrics

Total Leverage = Total Debt / LTM EBITDA (typically 4.0-6.5x for PE deals)
Senior Leverage = Senior Debt / LTM EBITDA (typically 3.0-4.5x)
Interest Coverage = EBITDA / Total Interest Expense (minimum 2.0x)
Fixed Charge Coverage = (EBITDA - Capex) / (Interest + Mandatory Amort) (minimum 1.2x)

Debt Schedule Mechanics

Mandatory amortization:

• Scheduled principal payments (e.g., 1% per year for TLB, 5-10% for TLA)
• Contractual obligation regardless of cash flow

Optional prepayment (voluntary):

• Available free cash flow after mandatory payments
• Prepay highest-cost debt first (waterfall)
• Subject to prepayment penalties on some instruments

Cash sweep:

• Percentage (typically 50-75%) of excess cash flow directed to debt repayment
• Excess cash flow = EBITDA - interest - taxes - capex - mandatory amort - working capital changes
• Steps down as leverage ratio improves (e.g., 75% above 4.0x, 50% at 3.0-4.0x, 25% below 3.0x)

Free Cash Flow to Equity

EBITDA
- Cash Interest Expense
- Cash Taxes
- Capital Expenditures
- Change in Net Working Capital
- Mandatory Debt Amortization
= Free Cash Flow Available for Optional Prepayment / Cash Sweep

Methodology

Step-by-Step LBO Build

1. Set entry assumptions — purchase price, entry multiple, transaction fees
2. Build sources & uses — balance debt capacity against equity check
3. Construct operating model — revenue, EBITDA, capex, working capital (5-7 year projection)
4. Build debt schedules — for each tranche: opening balance, interest, mandatory amort, optional prepay, closing balance
5. Calculate free cash flow — determine cash available for debt service and paydown
6. Model cash sweep — apply excess cash flow percentage to debt reduction
7. Set exit assumptions — exit year (typically Year 3-5), exit multiple
8. Calculate exit enterprise value — exit EBITDA × exit multiple
9. Compute equity value at exit — exit EV minus remaining net debt
10. Calculate returns — IRR, MOIC, cash-on-cash

Return Calculations

MOIC (Multiple of Invested Capital):

MOIC = Exit Equity Value / Initial Equity Investment

Example:
Sponsor equity invested: $500m
Exit equity value: $1,250m
MOIC: 2.5x

IRR (Internal Rate of Return):

IRR solves for r in: -Equity₀ + Σ(Dividends_t / (1+r)^t) + Exit Equity / (1+r)^n = 0

Typical PE targets:
- 20-25% gross IRR (before fees)
- 2.0-3.0x MOIC over 4-5 year hold

Include interim dividends/recapitalizations in IRR calculation if applicable.

Sensitivity Analysis

Two-way tables to construct:

Table 1: Entry Multiple vs Exit Multiple

IRR           | Exit 8.0x | Exit 9.0x | Exit 10.0x | Exit 11.0x
Entry 8.0x    |   ___%    |   ___%    |    ___%    |    ___%
Entry 9.0x    |   ___%    |   ___%    |    ___%    |    ___%
Entry 10.0x   |   ___%    |   ___%    |    ___%    |    ___%

Table 2: EBITDA Growth vs Leverage

IRR              | 4.0x Lev | 4.5x Lev | 5.0x Lev | 5.5x Lev
EBITDA CAGR 3%   |   ___%   |   ___%   |   ___%   |   ___%
EBITDA CAGR 5%   |   ___%   |   ___%   |   ___%   |   ___%
EBITDA CAGR 8%   |   ___%   |   ___%   |   ___%   |   ___%

Table 3: MOIC by Exit Year

           | Year 3 | Year 4 | Year 5 | Year 6 | Year 7
MOIC       |  ___x  |  ___x  |  ___x  |  ___x  |  ___x
IRR        |  ___%  |  ___%  |  ___%  |  ___%  |  ___%

Maximum Purchase Price (Ability to Pay)

Work backwards from target IRR:

1. Set target IRR (e.g., 20%) and hold period (e.g., 5 years)
2. Assume exit multiple and projected exit EBITDA
3. Calculate required exit equity value
4. Back into maximum entry equity = exit equity / (1 + IRR)^n
5. Add debt capacity to get maximum enterprise value
6. Implied maximum entry multiple = max EV / entry EBITDA

Quality Gate

Before finalizing an LBO model, verify:

• Sources equal uses exactly
• Debt capacity is realistic for the sector (check leverage vs comparable LBOs)
• Interest coverage ratio stays above 2.0x throughout the projection
• Cash balance never goes negative (model a revolver as liquidity backstop)
• Debt paydown waterfall follows seniority (senior before subordinated)
• Cash sweep mechanics step down with leverage improvement
• Exit multiple assumption is justified (typically assume no expansion)
• IRR includes management fees and carry structure if modeling net returns
• Sensitivity tables cover meaningful range of entry/exit multiples and growth rates
• Circular reference from cash interest on revolver is resolved (iterate or break)
• PIK interest compounds correctly (adds to principal, does not consume cash)
• Working capital and capex assumptions are consistent with operating model
• Transaction and financing fees are realistic (2-4% of EV for transaction, 2-3% of debt for financing)
