Merger Model — Key Mechanics

Sources & uses, goodwill calculation, pro forma EPS, and synergy modeling. A complete walkthrough of the IB deal model using a real industrial acquisition scenario.

The Deal Overview

A merger model is the quantitative backbone of an M&A advisory engagement. It answers two fundamental questions: (1) what does the deal cost and how is it funded, and (2) what happens to the combined company's financials after close? We will walk through every major section using a realistic industrial acquisition.

The acquirer is paying 12.0x EBITDA for the target — in line with the acquirer's own trading multiple of 12.5x, suggesting this is a strategic acquisition at a fair price, not a distressed purchase or a stretched premium deal. The target's $300M of existing debt must be refinanced at close (standard in most acquisitions).

Step 1 — Sources & Uses

Every merger model begins with the sources & uses table. It is the balance sheet of the transaction itself — every dollar that flows in (sources) must equal every dollar that flows out (uses). If they don't balance, the model has an error.

The deal is primarily debt-financed ($2,222M of new debt on top of the acquirer's existing $2,500M), which is typical for an investment-grade industrial acquirer with stable cash flows. The 5% stock component gives target management a small equity stake in the combined company — a common retention mechanism.

Step 2 — Purchase Price Allocation and Goodwill

After close, the acquirer's accountants must allocate the purchase price to the target's net assets at fair value. Anything left over is goodwill — the premium paid for expected future economic benefits (brand, customer relationships, synergies).

The $1,800M of goodwill goes on the acquirer's balance sheet and is NOT amortized under US GAAP (ASC 350 — Intangibles). Instead, it is tested annually for impairment. If the acquisition underperforms, goodwill impairment charges can be large and are non-cash but hit the income statement.

The $150M PP&E step-up and $200M of identified intangibles DO create incremental D&A. The intangibles are typically amortized over 5–15 years; PP&E step-up is depreciated over the remaining useful life of the assets. This is an important income statement impact.

Step 3 — Synergy Modeling

Synergies are what justify paying a premium. Bankers model them in two categories: cost synergies (easier to achieve and quantify) and revenue synergies (harder to achieve, often discounted by the market). The ramp matters — synergies rarely hit on Day 1.

Revenue synergies are kept at zero in Year 1 because they require sales team integration, training, and pipeline development. Conservative analysts often haircut revenue synergies by 50% because they are highly uncertain. Cost synergies, by contrast, are often given more credit because headcount and facility decisions are largely under management control.

Step 4 — Pro Forma Income Statement (Year 1)

Combine both companies' income statements, layer in the deal adjustments (incremental D&A, interest expense, synergies, integration costs), and compute pro forma EPS.

Year 1 is substantially dilutive — driven by $155M of incremental interest expense on the new debt and $95M of integration costs. This is expected and acceptable as long as Year 2–3 shows a credible path to accretion. Sophisticated investors look through Year 1 noise.

Step 5 — Accretion/Dilution Timeline

The accretion/dilution story is really a Year 1-to-Year-3 trajectory. Year 1 dilution driven by integration costs is expected. By Year 3, synergies have ramped and integration costs have faded — the deal should be accretive.

The deal reaches EPS neutrality in Year 2 and becomes meaningfully accretive in Year 3, once the full synergy ramp is realized and integration costs have faded. This is the standard "J-curve" pattern in industrial M&A: pain upfront, gain over time. A well-structured bank book will present this trajectory explicitly.

Step 6 — Credit Metrics Post-Deal

Beyond EPS, the acquirer's credit metrics will be scrutinized by rating agencies, lenders, and fixed income investors. Heavy debt loads can trigger rating downgrades, widen spreads on all outstanding debt, and constrain future borrowing capacity.

The leverage jump from 2.4x to 4.2x net debt/EBITDA is likely to push the acquirer from investment-grade (BBB) to high-yield territory (BB/BB+). This is a significant consequence: high-yield issuers face higher borrowing costs, more restrictive covenants, and a smaller investor base. Management would typically commit to a deleveraging plan (target ≤3.0x by Year 3) to reassure ratings agencies.
