Lesson Objective: To construct the core Accretion/Dilution model that assesses the impact of the transaction on the acquirer’s earnings per share (EPS), incorporating the impact of financing costs, synergies, purchase accounting adjustments, and the combined entity’s pro forma tax rate.

In-Depth Notes:

1. The Core Concept of Accretion/Dilution:
The Accretion/Dilution analysis is the primary financial metric used by public company acquirers to evaluate a deal. It answers the question: “Will the acquisition increase (accrete) or decrease (dilute) the acquirer’s EPS relative to its standalone EPS?”

• Accretion: If the combined entity’s pro forma EPS is higher than the acquirer’s standalone EPS, the deal is “accretive.” This is generally viewed favorably by shareholders (as long as the EPS growth is not driven by unsustainable accounting gimmicks).

• Dilution: If the combined entity’s pro forma EPS is lower than the acquirer’s standalone EPS, the deal is “dilutive.” This is generally viewed negatively, as it reduces shareholder earnings. Dilutive deals can still be value-creative in the long term if the strategic rationale (e.g., future growth potential) justifies the short-term EPS hit.

2. The Accretion/Dilution Formula:
The model calculates a single percentage to express the impact:

Accretion/Dilution (%) = (Pro Forma EPS / Standalone Acquirer EPS) – 1

• Standalone Acquirer EPS: The acquirer’s projected EPS without the transaction.

• Pro Forma EPS: The combined EPS after the transaction.

3. Building the Accretion/Dilution Model:
The model requires several key calculations:

• Step 1 – Determine the Net Increase to EBIT (Pre-Tax Income):

  • The Target’s Net Income Contribution: The target’s standalone net income is added to the acquirer’s net income.

  • Synergies: The expected cost and revenue synergies are added to the combined EBIT.

  • Transaction Integration Costs: One-time integration costs (e.g., severance, facility closure costs) are subtracted in the first year of the forecast.

  • Incremental D&A (Purchase Accounting): The acquisition will typically increase the value of PP&E and identifiable intangible assets (Step-Up). This increases the annual depreciation and amortization expense. This is subtracted from EBIT.

• Step 2 – Determine the Net Increase to Interest Expense (Financing Impact):

  • New Debt Interest: The interest expense on the new debt raised to finance the transaction is subtracted. The interest rate is based on the new debt’s yield.

  • Repayment of Target’s Debt: The interest expense that the target was paying on its existing debt is eliminated (since the debt was repaid at closing). This is a “saving” that partially offsets the new interest expense.

  • Fees and Amortization of Financing Costs: Financing fees are amortized over the life of the debt (adding to non-cash D&A).

• Step 3 – Calculate Pro Forma Pre-Tax Income: Acquirer Pre-Tax Income + Target Pre-Tax Income + Synergies - Integration Costs - Incremental D&A - Net Interest Expense Impact.

• Step 4 – Calculate Pro Forma Taxes: The pro forma tax rate is typically the acquirer’s marginal tax rate (unless the target operates in a significantly different tax jurisdiction). The tax rate must account for the tax-deductibility of interest expense and the tax shield from the step-up in D&A.

• Step 5 – Calculate Pro Forma Net Income: Pro Forma Pre-Tax Income x (1 - Pro Forma Tax Rate).

• Step 6 – Calculate Pro Forma EPS: Pro Forma Net Income / Pro Forma Fully Diluted Shares Outstanding.

  • New Shares Issued: If the deal is financed with stock, the number of new shares issued must be added to the acquirer’s share count.

  • Target’s Shares Converted: The number of target shares converted into acquirer shares must be added.

  • Rollover Equity: Any management rollover equity is added to the share count.

4. The “Breakeven” Synergy Analysis:
A critical component of the Accretion/Dilution analysis is determining the “breakeven synergies” required to make the deal accretive.

• The Breakeven Calculation: The model uses Goal Seek to determine the minimum level of synergies required to make the Pro Forma EPS equal to the Standalone Acquirer EPS. This is a critical metric for the investment committee. If the required synergies are unrealistically high (e.g., 20% of the target’s revenue), the deal is risky. If the required synergies are low (e.g., 2% of revenue), the deal is safe.

• The “Synergy Bridge”: A waterfall chart that shows the starting point (Acquirer EPS), the dilution from financing costs, the dilution from purchase accounting (D&A step-up), and the accretion from synergies. This bridge visually shows how the deal moves from dilution to accretion (or vice versa).

5. The “Stub Period” EPS (Critical for Deal Timing):
If the deal closes mid-year, the pro forma EPS calculation must account for a “stub period.”

• The Mechanics: The model calculates the EPS for the stub period by weighting the acquirer’s standalone EPS for the part of the year before the deal closes and the pro forma EPS for the part of the year after the deal closes.

• Formula: Stub Period EPS = (Acquirer EPS x Pre-Closing Months/12) + (Pro Forma EPS x Post-Closing Months/12).

• Global Nuance: In the US, deal closings are often timed to the end of a fiscal quarter to simplify accounting. In Europe, deal closings are often subject to regulatory approvals (antitrust, foreign investment), making stub period assumptions highly uncertain. The model must include a “Closing Date Sensitivity” toggle.
