Investment Banking Analyst Interview Questions (Valuation & M&A)

A DCF values a company based on the present value of its projected free cash flows. Start by projecting unlevered free cash flows for a forecast period, typically five to ten years. Unlevered free cash flow equals EBIT times one minus the tax rate, plus depreciation and amortization, minus capital expenditures, minus changes in working capital. This represents cash available to all capital providers before financing costs.

Next, calculate terminal value to capture value beyond the forecast period – either using a perpetuity growth method or an exit multiple approach. Discount both the projected cash flows and terminal value to present value using the Weighted Average Cost of Capital (WACC). The sum equals enterprise value. Subtract net debt to arrive at equity value, then divide by diluted shares outstanding for equity value per share. The key is defending your assumptions – revenue growth, margins, discount rate, and terminal value assumptions significantly impact the output.

There are two approaches to terminal value. The perpetuity growth method assumes cash flows grow at a constant rate forever. The formula is: Final Year Free Cash Flow times one plus the growth rate, divided by the discount rate minus the growth rate. The growth rate should be modest – typically around GDP growth or inflation – since no company grows faster than the economy indefinitely.

The exit multiple approach applies a trading multiple to the terminal year’s financial metric – for example, terminal year EBITDA times an EV/EBITDA multiple from your comparable companies. This method doesn’t assume perpetual growth but relies on the assumption that market multiples will remain relatively stable. Both methods should yield similar results if assumptions are consistent. I typically calculate both as a sanity check and present terminal value as a range.

WACC is the Weighted Average Cost of Capital – the blended required return for all capital providers based on the company’s capital structure. The formula weights the cost of equity and after-tax cost of debt by their respective proportions of total capital. Cost of debt is multiplied by one minus the tax rate because interest is tax-deductible.

Cost of equity is calculated using the Capital Asset Pricing Model (CAPM): risk-free rate plus beta times the equity risk premium. Beta measures the stock’s volatility relative to the market. For private companies, you unlever comparable company betas, average them, and relever to the target’s capital structure. WACC typically ranges from high single digits to low double digits for most companies. Lower WACC means higher present values, so this assumption significantly impacts DCF output.

Levered beta measures a company’s stock volatility relative to the market including the effects of its capital structure – debt amplifies both returns and risk. Unlevered beta removes the impact of debt, isolating the business risk inherent in the company’s operations. It represents how risky the core business is regardless of how it’s financed.

In valuation, we unlever comparable company betas to remove their specific capital structures, average the unlevered betas to get industry business risk, then relever using the target company’s capital structure. The relevering formula adds back the risk associated with the target’s specific debt level. This ensures we’re capturing the appropriate risk premium for the target’s actual financing rather than blindly applying another company’s levered beta.

An acquisition is accretive if the combined company’s earnings per share exceeds the acquirer’s standalone EPS; it’s dilutive if combined EPS is lower. The analysis compares what you gain (target’s earnings contribution) versus what you give up (shares issued or interest on debt). For stock deals, you calculate how many shares the acquirer issues and whether the target’s earnings contribution exceeds the dilution from additional shares.

For cash or debt-financed deals, you compare the target’s earnings to the after-tax interest cost on debt used for financing. If you pay cash, you also lose interest income on that cash. Synergies improve accretion by adding to combined earnings. Purchase accounting adjustments – like increased depreciation from asset write-ups or amortization of intangibles – typically reduce reported earnings. The timeline matters too; a deal might be dilutive initially but become accretive as synergies are realized.

Start by determining the purchase price and financing mix – how much cash, debt, and stock. Create a sources and uses schedule showing where funds come from (debt, equity, cash on hand) and where they go (equity purchase, debt refinancing, transaction fees). Adjust the target’s balance sheet for purchase accounting – write assets to fair value, create goodwill for the excess of purchase price over fair value of net assets.

Project the combined company’s financials. Add the acquirer’s and target’s income statements, incorporating synergies and dis-synergies. Adjust for financing costs – interest on new debt, foregone interest on cash used, shares issued for stock consideration. Apply purchase accounting adjustments like increased D&A from asset write-ups. Calculate combined net income and EPS. Compare to the acquirer’s standalone EPS to determine accretion or dilution. Analyze at various purchase prices and financing mixes to understand sensitivities.

Goodwill is an intangible asset created in acquisitions when the purchase price exceeds the fair value of identifiable net assets acquired. It represents the premium paid for factors that aren’t separately identifiable – brand value, customer relationships, assembled workforce, and expected synergies. Goodwill only appears through acquisitions; you can’t create it internally.

For example, if you pay $100 million for a company with $70 million in fair value of net assets, you record $30 million in goodwill. Under current accounting rules, goodwill isn’t amortized but is tested annually for impairment. If the acquired business underperforms, goodwill may be written down, creating a non-cash charge. Understanding goodwill is important for M&A analysis because it affects reported assets and can create future earnings volatility through impairment charges.

Synergies are the additional value created by combining two companies that wouldn’t exist if they remained separate. Cost synergies come from eliminating redundancies – consolidating facilities, reducing headcount, leveraging purchasing power, and eliminating duplicate functions. These are typically more predictable and achievable. Revenue synergies come from cross-selling products, entering new markets, or combining capabilities to win business neither could alone. These are harder to achieve and often take longer to realize.

Acquirers must balance synergy expectations against execution risk. Announced synergy targets often prove optimistic, and integration costs can exceed expectations. When valuing synergies, apply a discount for execution risk and consider timing – synergies aren’t realized immediately. In competitive auctions, buyers willing to pay more for synergies may win, but overpaying for synergies that don’t materialize destroys value. The best synergy analysis is specific and bottoms-up, identifying exactly where savings or growth will come from.

A Leveraged Buyout (LBO) is an acquisition financed primarily with debt, where the acquired company’s cash flows and assets serve as collateral. Private equity firms typically execute LBOs, contributing a relatively small equity portion while borrowing the majority of the purchase price. The goal is to generate returns through debt paydown, operational improvements, and eventual exit at a higher valuation.

LBOs work best for companies with stable, predictable cash flows that can service significant debt loads. Ideal candidates have strong market positions, limited capital requirements, opportunities for operational improvement, and potential for strategic exits. Industries with recurring revenue, contractual cash flows, or non-cyclical demand are attractive. Highly cyclical businesses or those requiring heavy capital investment are riskier LBO candidates because cash flow volatility threatens debt service ability.

Start with the transaction structure – purchase price, financing mix (debt tranches and equity), and sources and uses. Determine how much senior debt, subordinated debt, and equity the deal requires. Project the target’s operating performance over the holding period, typically five years. Model revenue growth, margin expansion, and working capital efficiency based on the investment thesis.

Project debt paydown using excess cash flow after debt service. Calculate the exit value using an assumed exit multiple applied to projected EBITDA. Determine proceeds to equity holders after debt repayment and calculate returns – IRR (Internal Rate of Return) and MOIC (Multiple on Invested Capital). Sensitize the model to key assumptions: entry multiple, exit multiple, revenue growth, margin improvement, and debt paydown. PE firms typically target IRRs above twenty percent and MOICs above two times.
