M&A

What Is Merger Model?

A merger model combines the financial statements of an acquirer and target to assess the pro forma impact of an M&A transaction, including accretion/dilution to EPS, combined credit metrics, and the overall financial profile of the combined entity.

What Is a Merger Model?

A merger model combines two companies' financials to evaluate a potential acquisition. It is one of the core models built by IB analysts and is essential for M&A advisory.

Key Components

Standalone projections for both companies. Transaction assumptions: purchase price, funding mix (cash/stock/debt), fees, and synergies. Purchase price allocation determines goodwill and new intangibles. Pro forma statements combine both companies with all adjustments.

Building the Model

Step 1: Standalone models for both companies. Step 2: Purchase price and implied multiples. Step 3: Funding structure specification. Step 4: Goodwill calculation. Step 5: Adjustment entries for financing costs, synergies, transaction costs, and new intangible amortization. Step 6: Combine financials. Step 7: Calculate pro forma EPS (accretion/dilution). Step 8: Analyze credit metrics.

Outputs

Accretion/dilution to EPS over multiple years, pro forma leverage and coverage, contribution analysis (revenue/EBITDA/earnings splits), synergy sensitivity, and purchase price sensitivity.

In Practice

Merger models are built for buy-side advisory (evaluate and price), sell-side advisory (demonstrate value), and fairness opinions. They answer: Can the acquirer afford it? Will it be accretive? What financing is optimal? How much can be paid before value is destroyed? What synergy level makes it work?

Why Interviewers Ask About This

The merger model is a critical technical skill. Interviewers ask candidates to walk through a simplified model, explain accretion/dilution, or describe how funding sources affect outcomes. Fluency with purchase price allocation through pro forma EPS is essential for M&A roles.

Common Mistakes

Forgetting lost interest income on cash used for the acquisition

Not phasing synergies over multiple years

Ignoring transaction costs that reduce pro forma earnings

Failing to create new intangible assets and corresponding amortization

Related Terms

Enterprise Value (EV)

Valuation

Enterprise Value represents the total value of a company's operations, calculated as market capitalization plus debt, minority interest, and preferred shares, minus cash and cash equivalents. It reflects what an acquirer would pay to own the entire business.

Goodwill

Accounting

Goodwill is an intangible asset created in an acquisition when the purchase price exceeds the fair value of the target's identifiable net assets. It represents the premium paid for synergies, brand value, workforce, and other factors that cannot be separately identified.

Accretion/Dilution Analysis

M&A

Accretion/dilution analysis determines whether a proposed M&A transaction will increase (accretive) or decrease (dilutive) the acquirer's earnings per share. It is one of the most critical tests used by boards and bankers to evaluate the financial impact of a deal.

Synergies

M&A

Synergies are the additional value created when two companies combine, categorized as cost synergies (expense reductions from eliminating redundancies) or revenue synergies (incremental sales from cross-selling). They are the key justification for paying acquisition premiums in M&A.

Due Diligence

M&A

Due diligence is the comprehensive investigation of a target company before an M&A transaction closes. It covers financial, legal, operational, tax, and commercial aspects to identify risks, validate assumptions, and inform the final purchase price and deal terms.

Frequently Asked Questions

What are the key assumptions?

Purchase price, funding mix (cash/stock/debt), synergies and phase-in, transaction costs, tax rate, and purchase price allocation. Each significantly impacts accretion/dilution.

How does funding mix affect the model?

Cash loses interest income, debt adds interest expense, stock dilutes shares. An optimal mix minimizes dilution while maintaining acceptable credit metrics. Most large deals use a combination.

What is contribution analysis?

It shows what percentage of combined revenue, EBITDA, and earnings each company contributes. It helps determine whether the exchange ratio in a stock deal fairly reflects each party's contribution.
