William Blair Paper LBO 2027: How to Walk Through It Step by Step

Walk through it in five steps: purchase price, financing, cash flows to pay down debt, exit value, then IRR from equity in versus equity out. The William Blair paper LBO interview prompt is commonly reported by candidates, and interviewers care about logical sequencing and clean assumptions, not arithmetic perfection.

What William blair paper LBO interview Assess

A paper LBO tests whether you understand how leverage creates returns. The interviewer wants to hear the mechanics: entry valuation, debt structure, cash generation, and exit, linked into one coherent story. Getting lost in the middle signals you have memorised steps without understanding them. Expectations may vary by role and region; confirm on the firm's official careers page.

How to Answer Step by Step: william blair paper LBO interview

Purchase price. Start with enterprise value, typically as a multiple of EBITDA. State your assumption clearly: "Assume $100 million EBITDA at a 6x multiple, so $600 million enterprise value."
Financing. Split the price into debt and equity with a leverage assumption: "Assume 4x leverage, so $400 million of debt and $200 million of equity."
Cash flows. Project EBITDA, subtract interest, taxes, capex, and working capital changes to get free cash flow, and use it to pay down debt each year.
Exit. At year five, apply an exit multiple to final EBITDA for enterprise value, subtract remaining debt for equity value.
IRR. Compute the return from $200 million in to the exit equity out: "That implies roughly a 20-something percent IRR," and sanity-check whether it clears a typical hurdle.

State assumptions as you go; interviewers will adjust them to test you.

Common Mistakes

Silent arithmetic. Narrate every step; the interviewer is grading your logic, not your mental math.
Forgetting debt paydown. Cash flow must reduce debt each year, or the exit math breaks.
No sanity check. Always compare your IRR to a hurdle rate and comment on whether the deal works.
