Investment Banker interview questions

I bridge reported carve-out cash flow to a sustainable post-separation run rate before discounting it.

• Recast revenue and EBITDA to the deal perimeter, replacing parent allocations with recurring standalone costs and removing stranded parent costs that do not transfer.
• Normalize working capital, capital expenditures, and cash taxes for independent operations rather than carrying historical carve-out patterns forward.
• Model TSA payments and separation costs as finite cash flows, not terminal economics, and reconcile every adjustment to source financials.

WACC is the market-value-weighted after-tax cost of debt and cost of equity.

• Calculate equity cost with CAPM using a normalized risk-free rate, equity premium, and relevered beta.
• Use marginal borrowing cost for debt and multiply it by one minus the marginal tax rate.
• Weight debt and equity by market value and a sustainable target capital structure.

I remove each peer’s financing risk, estimate business risk, and apply the target leverage.

• Unlever beta with the peer tax rate and debt-to-equity ratio to obtain asset beta.
• Use the median of clean peers so one unusual capital structure does not drive the result.
• Relever with the subject company’s sustainable target debt-to-equity ratio.

I use it when cash flow is earned throughout the year rather than only at year-end.

• Discount annual cash flow by half a period less to reflect average receipt timing.
• Model a stub explicitly when the valuation date falls inside a fiscal year.
• Apply the same timing to terminal value and adjust for highly seasonal businesses.

I anchor it to sustainable nominal growth for a mature company in its end market.

• Keep it below long-run nominal GDP growth in the relevant currency and geography.
• Make terminal margins, working capital, and reinvestment consistent with that growth.
• Add a fade period if growth remains unusually high in the last forecast year.

I use forward trading evidence adjusted for the company’s expected terminal profile.

• Match the terminal metric and benchmark period, such as year-six EBITDA and forward EV/EBITDA.
• Normalize for the cycle and compare terminal growth, margin, and ROIC with peers.
• Calculate the implied perpetual growth rate at the selected WACC as a cross-check.

I test its share of enterprise value and the economics embedded in it.

• A very high share is a warning when the explicit forecast is short or loss-making.
• Compare implied growth and exit multiples with macro growth, peers, and precedents.
• Confirm mature margins and ROIC are defensible and reinvestment supports growth.

Higher rates usually reduce value, but I separate discount-rate and operating effects.

• A higher risk-free rate raises equity cost and often debt cost, increasing WACC.
• Terminal value is especially sensitive because it contains distant cash flows.
• Effects on demand or investment belong in cash flows and must not be counted again in WACC.

I prioritize similarity in business model and earnings drivers before size.

• Compare products, customers, geography, recurring revenue, growth, margins, and capital intensity.
• Separate close peers from broader references so weak analogs do not drive the median.
• Use unaffected prices and consensus from one date and document exclusions.

I bridge from diluted equity value by adding senior claims and subtracting nonoperating assets.

• Use current price and fully diluted shares, including in-the-money options and relevant awards.
• Add debt, preferred stock, noncontrolling interest, and material debt-like items.
• Subtract available cash and investments, treating leases consistently with the earnings metric.

I normalize the valuation numerator and earnings denominator under one convention.

• Remove material one-time gains, restructuring charges, and nonrecurring acquisition effects.
• Calendarize periods or use NTM estimates rather than comparing different forecast windows.
• Treat leases, stock compensation, and development costs consistently and reconcile consensus to filings.

I adapt public evidence for the private company’s scale, liquidity, governance, and data quality.

• Normalize owner compensation, related-party items, and nonrecurring expenses.
• Explain discounts for scale, concentration, or disclosure instead of applying a blanket discount.
• Apply EV multiples to matching metrics, bridge net debt separately, and present a range.

I select similar assets and buyer motives, then normalize value and earnings consistently.

• Use unaffected prices and financials from before credible deal speculation.
• Include assumed debt and claims while using standalone LTM or NTM earnings.
• Adjust for minority stakes, earnouts, divestitures, and unusual consideration.

Precedents often include payment for control and expected synergies absent from minority prices.

• Control lets a buyer direct strategy, use cash flow, and remove duplicated costs.
• Auctions and scarce strategic assets can raise price above unaffected trading value.
• Distressed sales or weak financing can reverse the pattern, so no premium is automatic.

It connects purchase price, financing, purchase accounting, combined earnings, and pro forma ownership.

• Sources and uses captures consideration, refinanced debt, fees, and funding.
• Purchase accounting allocates step-ups, deferred taxes, intangibles, and goodwill.
• Combined earnings drive EPS accretion or dilution, leverage, ownership, and sensitivities.

I convert the common-equity offer into total consideration and reconcile it to EV.

• Offer price times fully diluted shares gives equity purchase price with award treatment.
• Add debt assumed or repaid, preferred stock, minority interests, and debt-like obligations.
• Subtract only available acquired cash and keep fees separate from consideration.

It resets acquired assets and liabilities to fair value and creates post-deal earnings charges.

• Inventory and fixed-asset step-ups affect cost of sales and depreciation.
• Identifiable intangibles create amortization over estimated useful lives.
• Deferred taxes change net assets, while goodwill remains the residual.

It occurs when accounting basis rises but tax basis does not.

• Future book amortization exceeds tax deductions, creating a taxable temporary difference.
• The liability equals that difference times the applicable tax rate.
• It reduces acquired net assets and initially increases residual goodwill equally.

It reflects target earnings versus the incremental cost of buying and financing them.

• Cash loses interest, debt adds after-tax interest, and stock increases shares.
• Synergies add earnings while amortization, inventory step-up, and fees reduce them.
• Price, funding mix, close date, and accounting determine first-year EPS impact.

EPS accretion is an accounting result, not proof of adequate return on price.

• Cheap debt or a high buyer P/E can create accretion below the cost of capital.
• Overpaying for uncertain synergies can reduce intrinsic value while EPS rises.
• Compare acquisition ROIC with WACC and review DCF value, leverage, and integration costs.
