The paper LBO
Returns, an exit sensitivity, and the most you could pay. Do it on paper first; the checks below name the mistake if one slips in. Try new numbers gives a fresh deal aimed at the same skills.

Not triedHarbor Maintenance: the paper LBO
A maintenance company has entry EBITDA of 25 and is bought for 8× EBITDA on a cash-free, debt-free basis. New acquisition debt is 120. Sponsor equity also funds 4 of transaction fees. Hold for 5 years.
Exit EBITDA is 32 at 8×, and cumulative debt repayment is 10. Calculate sponsor returns.
Then change only the exit: EBITDA 28 at 7×, repayment unchanged. Finally: what is the most the sponsor could pay for a 20% IRR, holding the exit, debt, fees and timing fixed?
Assumptions
- All values in $ millions.
- The 10 of repayment is supplied after interest, taxes, capex and working capital. Don't subtract those again.
- No excess cash, interim distributions, additional equity, management dilution or exit fees.
- The downside changes the exit only. It is an isolated sensitivity, not a linked operating downside.
MODE 2 · ONE HOUR · IN THE WORKBOOK
The one-hour model
- Open the blank workbook. The Inputs tab is filled in; the Base tab is laid out and empty.
- Build revenue, EBITDA, D&A, interest, taxes, working capital and capex for five years.
- Run the debt schedule: 1% mandatory amortisation, then a full cash sweep, holding 5.0 of cash. Interest on beginning balances.
- Exit at 8.0× year 5 EBITDA; take off net debt; compute MOIC and IRR.
- Enter your outputs below.

Not triedHarbor Maintenance: check your one-hour model
Build the base case in the blank workbook, then enter your outputs here. Every check uses the conventions on the Inputs tab: interest on beginning balances, SOFR assumption plus spread with a floor, a 100% sweep after 1% mandatory amortisation, and a 5.0 minimum cash balance.
Assumptions
- All values in $ millions. Enter to one decimal unless asked otherwise.
MODE 3 · THREE HOURS · DOWNSIDE AND MEMO
The linked downside
The largest customer, 18% of revenue, doesn't renew after year 1. Transition costs of 14.0 hit in year 2, SOFR rises to 5.00%, and the exit multiple falls to 7.0×. Run it through the whole model on the Downside tab, add the revolver, and see whether the business can pay its way.
PRACTICE · LEVEL 3 · ABOUT 180 MIN
Not triedHarbor Maintenance: check your linked downside
Run the downside through the whole model: the largest customer leaves after year 1, transition costs of 14.0 land in year 2, SOFR rises to 5.00% from year 2, and the exit multiple falls to 7.0×. Add the revolver: 20.0 committed, 7.5% on drawn balances, drawn only when cash would fall below the 5.0 minimum, repaid before any sweep.
Assumptions
- All values in $ millions.
