AI for Merger Models: Claude Tools for M&A Accretion/Dilution and Pro Forma Analysis

Merger Models and AI

Merger modeling (sometimes called accretion/dilution analysis or pro forma combination analysis) is the core analytical tool for evaluating acquisitions from the acquirer's perspective. It tests whether a deal enhances or reduces EPS, computes the combined entity's credit profile, and models synergy impact. Claude with ClaudeFinLab builds complete merger models from deal terms, allocates purchase price, and stress-tests the accretion across different deal structures.

Accretion/Dilution Analysis

• "Accretion/dilution for an all-stock deal: Acquirer EPS $3.20, shares outstanding 84M. Target net income $28M, purchase price $480M. Exchange ratio: $480M / acquirer share price $38 = 12.63M new shares issued. New share count: 84M + 12.63M = 96.63M shares. Combined net income: acquirer NI $268.8M + target NI $28M = $296.8M. But: add back D&A step-up ($18M pre-tax → $13.5M after-tax at 25% tax rate → subtract). And add synergies (Year 1: $15M pre-tax → $11.25M after-tax). Pro forma EPS: $296.8M − $13.5M + $11.25M = $294.55M / 96.63M = $3.05. Accretion/dilution: ($3.05 − $3.20) / $3.20 = -4.7% dilutive."
• "Accretion/dilution for a cash deal: same acquisition but funded 50% cash ($240M) at 6.5% pre-tax cost + 50% debt ($240M) at 7.2% pre-tax cost. After-tax financing cost: ($240M × 6.5% + $240M × 7.2%) × (1 − 25%) = ($15.6M + $17.28M) × 75% = $24.66M annual. Combined NI: $296.8M − $24.66M (financing) − $13.5M (D&A step-up) + $11.25M (synergies) = $269.89M / 84M shares (no dilution from new shares) = $3.21. Accretion: +0.3% — modestly accretive."
• "Breakeven analysis: at what price per share (all-stock deal) is the transaction EPS-neutral? If target NI = $28M + $11.25M synergies − $13.5M D&A step-up = $25.75M incremental. At neutral EPS $3.20: new shares needed = $25.75M / $3.20 = 8.05M shares. Share price = $480M / 8.05M = $59.63 (vs current $38). Acquirer would need to be at $59.63 for the deal to be EPS-neutral. What is the implied premium?"

Purchase Price Allocation (PPA)

• "Purchase price allocation for $480M acquisition: Target book value net assets $85M. Step 1 — identify and value tangible assets at fair value: PP&E step-up from $42M book to $58M fair value (+$16M). Inventory step-up from $28M to $34M (+$6M). Total tangible step-up $22M. Step 2 — identified intangibles: customer relationships $65M (useful life 12 years → $5.4M annual amortization); technology IP $28M (5 years → $5.6M); trade name $12M (indefinite life — no amortization). Step 3 — goodwill = $480M − ($85M + $22M + $65M + $28M + $12M) = $268M."
• "D&A step-up impact on pro forma earnings: identified intangible amortization: customer relationships $5.4M + technology $5.6M = $11M/year. PP&E step-up depreciation: $16M / 10 years = $1.6M/year. Inventory step-up ($6M) expensed in Year 1 only (COGS). Total D&A step-up Year 1: $11M + $1.6M + $6M = $18.6M. Years 2+: $12.6M (no inventory step-up recurrence). After-tax impact Year 1: $18.6M × 0.75 = $13.95M earnings reduction."
• "Goodwill impairment sensitivity: goodwill $268M allocated to a single reporting unit. Reporting unit fair value at acquisition: $480M (purchase price). If enterprise value declines 30% to $336M, and reporting unit carrying value is $480M → impairment test fails ($336M < $480M carrying). Impairment charge: $480M − $336M = $144M (non-cash). Impact on equity: reduces retained earnings $144M. Impact on EPS: $144M / 84M shares = $1.71 EPS charge. What leverage covenant metric (debt/EBITDA) is affected if the impairment reduces EBITDA by being in the covenant definition?"

Deal Structure Analysis

• "Cash vs stock vs mixed deal comparison: $480M acquisition. Option A: 100% cash (debt-financed $240M + existing cash $240M). Option B: 100% stock (exchange ratio 12.63M new shares). Option C: 60/40 mixed ($288M cash + $192M stock = 5.05M new shares). Compare: (1) EPS impact of each structure; (2) leverage post-close; (3) earnings retention (cash has interest cost, stock has dilution, mixed has both); (4) tax treatment (cash is taxable to target shareholders; stock may be tax-free under IRC §368)."
• "Collar structure in stock deals: in volatile markets, fixed exchange ratios create price risk for both parties. A collar protects both sides: fixed ratio only if acquirer stock stays in a $34-$42 band around $38. Below $34: ratio adjusts so target shareholders receive value = $34 × base ratio / $38. Above $42: ratio adjusts downward. Model the target shareholder's proceeds at acquirer prices: $28, $34, $38, $42, $48. When does the collar provide protection and when does it leave price risk?"

Synergy Analysis

• "Cost synergy analysis: combined entity will reduce headcount by 180 people (target redundant back-office functions). Average total comp per person $85K (salary + benefits). Annual savings: 180 × $85K = $15.3M. One-time restructuring costs: 180 × $25K severance + integration costs $8.4M = $12.9M. Revenue synergies (Year 3): cross-sell acquirer products to target customers — expected $8M incremental revenue at 40% margin = $3.2M. Total synergies Year 3: $15.3M cost + $3.2M revenue = $18.5M. NPV of synergies at 10% WACC over 5 years: PV = $18.5M / 10% = $185M (perpetuity). This represents 38.5% of the $480M purchase price — a reasonable synergy assumption?"
• "Synergy risk-adjusted value: cost synergies have higher confidence (85%) than revenue synergies (40%). Risk-adjusted synergy value: $15.3M × 85% + $3.2M × 40% = $13.0M + $1.28M = $14.28M risk-adjusted annual. Synergy NPV at 10%: $142.8M. The acquirer pays $480M and gets $142.8M of risk-adjusted synergies = 29.8% of price. Maximum price a buyer should pay to avoid synergy overpayment: standalone value + synergies NPV = (target standalone value $380M) + $142.8M = $522.8M. So $480M is within range, assuming the standalone $380M valuation holds."

Contribution Analysis

• "Contribution analysis for swap ratio negotiation: combined entity — acquirer contributes 78% of revenue, 81% of EBITDA, 76% of book value, 74% of net income. Target contributes 22%, 19%, 24%, 26%. Average contribution to value drivers: ~23% for target. If the deal implies target shareholders own 13.1% of combined (12.63M / 96.63M), are they getting fair value for their 23% contribution? This creates negotiating tension — target will argue for a higher exchange ratio."
