Model Assumptions
  • Educational purposes only - not financial advice
  • 7 inputs used - share price is explicit (not derived from P/E)
  • Diluted basis - EPS and shares should be on same diluted basis
  • No purchase accounting - intangible amortization, write-ups excluded
  • No transaction costs - advisory/financing fees excluded
  • Synergies fully realized - run-rate, after-tax, Year 1
  • Single-period analysis - no multi-year EPS trajectory
  • Cash is debt-funded - at the stated after-tax rate

Understanding Accretion/Dilution Analysis

What is Accretion/Dilution Analysis?

Accretion/dilution analysis measures the pro forma effects of an M&A transaction on the acquirer's earnings per share (EPS). By comparing post-deal EPS to standalone EPS, analysts determine whether a transaction creates or destroys shareholder value on an EPS basis.

Core Logic
Accretive: Pro Forma EPS > Standalone EPS
Dilutive: Pro Forma EPS < Standalone EPS
Public companies generally avoid dilutive transactions

Cash vs Stock Financing Trade-off

Cash (Debt) Financing

Creates interest expense
Reduces pro forma net income by financing cost, but does not dilute share count. Favorable when cost of debt < acquirer's earnings yield.

Stock Financing

Dilutes share count
No interest expense, but increases shares outstanding. Favorable when acquirer's stock is highly valued (high P/E multiple).

Key Drivers of Accretion

  • Higher target earnings: More net income contribution improves pro forma EPS
  • Lower purchase price: Fewer new shares issued, less debt interest
  • Greater synergies: Cost savings and revenue enhancements boost earnings
  • Cheaper financing: Lower interest rate on debt portion
  • Higher acquirer P/E: Stock consideration dilutes less per dollar
Crossover Premium: The maximum price an acquirer can pay before a deal turns dilutive. Sell-side advisors use this to push buyers to increase bids.
Limitations: This simplified model excludes purchase accounting (intangible amortization, write-ups), transaction costs, and multi-year EPS trajectories. Real M&A analysis involves significantly more complexity.

Frequently Asked Questions

Accretion/dilution analysis measures how an M&A transaction affects the acquirer's earnings per share (EPS). If pro forma EPS exceeds standalone EPS, the deal is accretive. If pro forma EPS falls below standalone EPS, the deal is dilutive. Public companies are generally reluctant to pursue dilutive transactions due to potential negative effects on share price.

A deal is accretive when pro forma EPS exceeds the acquirer's standalone EPS. This occurs when the target's earnings contribution (net income plus synergies minus financing costs) adds more to the numerator than the impact on the denominator from new shares issued or reduced earnings from interest expense. Higher target earnings, lower purchase price, cheaper financing, and greater synergies all increase accretion.

Cash financing creates interest expense that reduces pro forma net income, but doesn't dilute share count. Stock financing dilutes shares outstanding but adds no interest expense. The optimal mix depends on the acquirer's cost of debt (after-tax interest rate) versus its earnings yield (inverse of P/E ratio). When interest rate < earnings yield, cash financing is more accretive.

The crossover premium is the maximum price (or premium to target's unaffected share price) an acquirer can pay before a deal turns from accretive to dilutive. It's a key negotiation benchmark - sellers push buyers to this ceiling while buyers resist paying more than their accretion analysis supports. Note: this calculator helps analyze specific scenarios but does not directly solve for crossover premium.

Synergies (cost savings, revenue enhancements) flow directly to pro forma net income and improve accretion. Higher synergies allow acquirers to pay higher premiums while maintaining accretion. Synergy assumptions are often scrutinized in deal negotiations - sellers want buyers to credit more synergies (justifying higher prices), while buyers are cautious about achievability.

This calculator excludes purchase accounting (intangible amortization, asset write-ups), transaction costs (advisory fees, financing costs), and multi-year EPS trajectories. Real M&A models also consider cash flow impact, balance sheet effects, control premiums, and deal structure nuances. Use this for directional analysis and learning, not final deal decisions.
