Merger model in one page
Focus on the mechanics that change EPS: deal consideration, financing cost, synergies, and purchase accounting.
Core steps
- Set deal terms (price, mix, timing).
- Forecast standalone buyer and target.
- Add synergies and one-time costs.
- Run purchase accounting adjustments.
- Model financing impacts (interest, share count).
- Calculate pro forma EPS and accretion.
Accretion drivers
| Driver | Effect | Why it matters |
|---|---|---|
| Synergies | Accretive | Boosts EBITDA and EPS |
| Financing cost | Dilutive if high | Interest expense can erode EPS |
| Purchase accounting | Often dilutive | Intangible amortization reduces earnings |
Decision-ready conclusion
"If the synergy capture and financing cost keep EPS accretive within two years, the deal makes sense. Otherwise, the price or structure needs adjustment."
