Business Case Development for M&A

The business case provides the financial justification for an acquisition, demonstrating that the deal will create shareholder value and generate acceptable returns on investment.

What is an M&A Business Case?

An M&A business case is a comprehensive financial analysis that:

• Quantifies value creation from the acquisition
• Projects financial performance of combined entity
• Calculates ROI and other return metrics
• Demonstrates deal meets hurdle rates
• Identifies key value drivers and risks
• Provides financial scenarios (base, upside, downside)

Purpose: Secure internal approval (Board, IC) by proving the deal makes financial sense.

Business Case Components

1. Transaction Overview

Deal Summary

• Target company name and description
• Deal structure (cash, stock, combination)
• Purchase price and enterprise value
• Financing approach
• Expected close timeline

Deal Economics at a Glance

2. Financial Projections

Standalone Projections

Build 5-year standalone forecasts for both:

• Acquirer (current business trajectory)
• Target (based on historical performance + management projections)

Key Assumptions

• Revenue growth rates by segment
• EBITDA margins and operating leverage
• Capex and working capital needs
• Tax rates and NOLs
• D&A and amortization

Pro Forma Projections

Combine acquirer + target with adjustments:

• Synergies (revenue and cost)
• Deal costs (one-time integration expenses)
• Purchase accounting impacts (step-up depreciation, goodwill)
• Financing costs (interest on new debt)

3. Synergy Analysis

Revenue Synergies

Cost Synergies

Synergy Realization Timeline

• Year 1: [X]% of run-rate synergies
• Year 2: [X]% of run-rate synergies
• Year 3: 100% of run-rate synergies

Integration Costs

Rule of Thumb: Integration costs typically = 10-15% of deal value for transformational deals, 5-10% for bolt-ons.

4. Valuation Analysis

Valuation Methods

Run multiple methodologies to triangulate fair value:

Purchase Price Analysis

Purchase Price:              $500M
Less: Synergy PV (3-year):  ($150M)
Net Purchase Price:          $350M

Implied Net Multiples:
- Net EV/Revenue:            2.5x (vs. 3.5x gross)
- Net EV/EBITDA:             8.0x (vs. 11.5x gross)

Value Creation Bridge

5. Returns Analysis

Key Return Metrics

IRR Calculation

Year 0:  -$500M (purchase price) - $40M (transaction costs) = -$540M
Year 1:  $45M (incremental FCF)
Year 2:  $75M (incremental FCF)
Year 3:  $95M (incremental FCF)
Year 4:  $110M (incremental FCF)
Year 5:  $125M (incremental FCF) + $600M (terminal value)

IRR = 18.5%

Return Hurdles by Deal Type

6. Scenario Analysis

Three-Scenario Framework

Build detailed models for each scenario:

Base Case (60% probability)

• Management plan adjusted for conservatism
• 75% of identified synergies achieved
• Market conditions remain stable
• Integration proceeds on schedule

Upside Case (20% probability)

• Strong market tailwinds
• 100%+ synergies captured
• Revenue synergies materialize
• Faster integration

Downside Case (20% probability)

• Market headwinds or recession
• 50% of synergies achieved
• Integration delays/cost overruns
• Customer/employee attrition

Probability-Weighted Returns

Expected IRR = (60% × 18.5%) + (20% × 24.2%) + (20% × 12.1%) = 18.4%
Expected NPV = (60% × $120M) + (20% × $250M) + (20% × $40M) = $130M

Sensitivity Analysis

7. Financial Impact

P&L Impact (Pro Forma)

Balance Sheet Impact

Credit Metrics Impact

Equity Impact

8. Financing Plan

Sources & Uses

Financing Strategy

• Maintain investment-grade rating
• Target leverage of 2.5-3.0x Net Debt/EBITDA
• Refi existing revolver to $500M
• Commitment letter from banks secured
• Deleveraging plan: reach <2.0x by Year 3

Building the Business Case: Step-by-Step

Step 1: Gather Inputs

Required Data

• Target financial statements (3-5 years historical)
• Target management projections
• Acquirer financial model
• Market comps and transaction comps
• Synergy estimates from functional teams
• Integration cost estimates
• Financing terms and costs

Step 2: Build Financial Model

Model Structure

1. Historical actuals (3-5 years for both companies)
2. Standalone projections (5 years for both companies)
3. Transaction assumptions (purchase price, structure, financing)
4. Purchase price allocation (goodwill, intangibles, step-ups)
5. Pro forma adjustments (synergies, integration costs, financing)
6. Integrated projections (5 years pro forma P&L, BS, CF)
7. Returns calculations (IRR, NPV, ROIC, payback)
8. Scenarios (upside, base, downside)
9. Sensitivities (key drivers, tornado chart)

Model Best Practices

• Separate assumptions from calculations
• Color code (blue = input, black = formula, green = link)
• Include scenario toggles
• Build circular reference solver for revolver/cash
• Include detailed footnotes and sources

Step 3: Validate Assumptions

Sanity Checks

• Revenue growth rates vs. historical and market growth
• Margins vs. industry benchmarks and historical trends
• Synergies vs. % of revenue/cost base (reasonability)
• Integration costs vs. deal size and complexity
• Valuation multiples vs. comps range
• Return metrics vs. hurdle rates and alternatives

Red Flags

• ❌ Revenue growth >2x historical without clear drivers
• ❌ Margin expansion >500bps without specific initiatives
• ❌ Synergies >30% of target revenue (too aggressive)
• ❌ No integration costs (unrealistic)
• ❌ IRR just barely clears hurdle (no margin of safety)

Step 4: Test Scenarios

Scenario Testing Questions

• What if revenue growth is 50% lower than projected?
• What if synergies are only 50% realized?
• What if integration takes 2x longer and costs 2x more?
• What if we face a recession in Year 2?
• What if key customers leave (customer concentration risk)?

Break-Even Analysis

• What's the minimum synergy capture needed to hit hurdle rate?
• What's the maximum price we can pay and still create value?
• How long can we afford delayed synergy realization?

Step 5: Prepare Recommendation
