Walk Me Through an LBO: Interview Answer and Full Framework
The PE and IB interview LBO walkthrough: sources and uses, operating case, debt schedule, exit, MoIC and IRR, with a timed verbal structure and follow-ups.
PE · 5 min read
"Walk me through an LBO" is the core PE technical and a common IB follow-up once valuation basics are cleared. Interviewers want a structured tour of the model, not a history of leveraged buyouts. If you can narrate entry, financing, operations, debt paydown, exit, and returns in about 90 seconds, then survive follow-ups, you clear a huge filter.
The 90-second answer
"A leveraged buyout is buying a company using a mix of debt and equity. I start with entry enterprise value from EBITDA times an entry multiple, then build sources and uses so debt tranches plus sponsor equity plus any rollover fund the purchase price, fees, and refinancing needs. I project the operating case to free cash flow, run a debt schedule with interest, amortization, and optional prepay from excess cash, then exit at an exit multiple on forward EBITDA. Exit equity is exit EV minus net debt. MoIC is exit equity over entry equity, and IRR is the annualized return over the hold. Returns come from deleveraging, EBITDA growth, and multiple change."
Stop. Let them dig.
The full framework
Entry
Entry EV = Entry EBITDA × entry multiple. Bridge to equity value if needed.
Sources and uses
How the deal is funded and what cash is spent at close.
Operating case
Revenue, EBITDA, taxes, CapEx, NWC → free cash flow.
Debt schedule
Interest, mandatory amort, revolver, cash sweep.
Exit
Exit EV = Exit EBITDA × exit multiple. Subtract net debt.
Returns
MoIC, IRR, and attribution (delever / EBITDA / multiple).
Step 1: Entry valuation
Most prompts give LTM EBITDA and an entry multiple.
Entry EV = Entry EBITDA × Entry Multiple
Clarify LTM vs NTM if both appear. Paying "10x" of the wrong earnings base is a classic miss.
Step 2: Sources and uses
Uses (what you need at close):
- Equity purchase price / enterprise value economics (cash-free debt-free conventions matter)
- Refinance existing debt (often)
- Transaction fees and financing fees
- Minimum cash left on the balance sheet
Sources (how you fund it):
- New debt tranches (revolver, term loan, notes, mezz)
- Sponsor equity
- Management rollover
- Seller note (sometimes)
Sources must equal uses. Sponsor equity is often the plug.
Step 3: Operating case and free cash flow
You need a path from EBITDA to cash available for debt paydown:
EBITDA
− D&A (if you need EBIT)
− Cash interest (careful with timing / circularity)
− Taxes
− CapEx
− ΔNWC
± other
= Free cash flow available for debt repayment (definition varies by model)
In interviews, say your FCF definition. Do not pretend every shop uses the identical bridge.
Step 4: Debt schedule
Walk senior to junior:
- Beginning balance
- Draws / mandatory amortization
- Optional prepay (cash sweep)
- Interest (cash vs PIK if relevant)
- Ending balance
Revolver usually sits at the top of the sweep after minimum cash. Term loans amortize. Bonds may be interest-only with bullet maturity.
Step 5: Exit
Exit EV = Exit EBITDA × Exit Multiple
Exit Equity ≈ Exit EV − Ending Net Debt (+/− other adjustments)
Flat exit multiple is a common base case. Compression is a stress. Expansion needs a story.
Step 6: Returns
MoIC = Exit Equity ÷ Entry Equity
IRR ≈ MoIC^(1/n) − 1 (terminal-only shortcut)
Then attribution:
- Deleveraging: debt paydown increases equity value
- EBITDA growth: more earnings at a given multiple
- Multiple expansion / compression: exit vs entry multiple

Follow-ups you should expect
| Follow-up | Clean direction |
|---|---|
| What makes a good LBO candidate? | Stable FCF, leverage capacity, actionable plan, exit options |
| How do sponsors create returns? | Delever, grow EBITDA, multiple (least controllable) |
| What if exit multiple compresses one turn? | Walk the equity hit |
| Where does MoIC differ from IRR? | Timing / interim cash |
| How does a dividend recap change returns? | Pulls cash forward, can boost IRR |
| Revolver vs term loan? | Flexibility vs amortizing funded debt |
Weak vs strong walkthroughs
Weak
An LBO is when PE uses debt to buy a company and improve it and then sells it for a profit using IRR.
Strong
Structured tour of entry, S&U, FCF, debt schedule, exit equity, MoIC/IRR, and the three return drivers, with definitions stated as you go.
Paper LBO vs full walkthrough
The verbal walkthrough is the map. A paper LBO is the same map with numbers and mental math. A modeling test is the map in Excel under time. Learn them as one skill with three interfaces.
Practice plan
Day 1: memorize the 90-second script until boring.
Day 2: add a numeric paper LBO on top.
Day 3: explain debt schedule mechanics without notes.
Day 4: attribution on a finished case (flat multiple vs compression).
Day 5: mock with interruptions every 20 seconds.
Practice on SheetRank
Build full LBOs until sources equal uses and returns reconcile without hoping. Apollo-style cases grade the live model so your verbal walkthrough is describing work you have actually done.
