Pro Forma Financial Statements: How to Build Them for M&A and Planning
When Pro Forma Statements Are Used
Pro forma financials appear in virtually every major corporate transaction. Investment bankers build them for merger models, CFOs use them for capital planning, and management teams present them to boards to support strategic decisions. They’re also required in SEC filings (Form 8-K) for material acquisitions.
| Context | Purpose | Key Adjustments |
|---|---|---|
| M&A | Show combined entity financials | Purchase accounting, synergies, new debt/equity |
| Capital Raise (Debt) | Show post-financing leverage and coverage | New debt, interest expense, use of proceeds |
| Capital Raise (Equity) | Show post-offering dilution and cash position | New shares, use of proceeds, reduced leverage |
| Restructuring | Show financials after divesting or closing segments | Remove divested segment, restructuring charges |
| Strategic Planning | Show impact of new initiatives, pricing changes, expansion | Revenue/cost changes from the initiative |
Pro Forma Income Statement — M&A Context
The pro forma income statement in a merger model combines both companies’ P&Ls and layers in transaction adjustments. Here’s the structure:
| Line Item | Acquirer | Target | Adjustments | Pro Forma |
|---|---|---|---|---|
| Revenue | Acquirer revenue | Target revenue | Revenue synergies (phased) | Sum |
| COGS | Acquirer COGS | Target COGS | COGS synergies | Sum |
| Gross Profit | — | — | — | Revenue − COGS |
| Operating Expenses | Acquirer OpEx | Target OpEx | Cost synergies, incremental D&A from write-ups | Sum |
| EBIT | — | — | — | Gross Profit − OpEx |
| Interest Expense | Acquirer interest | Target interest (refinanced) | New acquisition debt interest | Sum |
| Pre-Tax Income | — | — | — | EBIT − Interest |
| Taxes | — | — | Blended tax rate | Pre-Tax × Tax Rate |
| Net Income | — | — | — | Pre-Tax − Taxes |
| Pro Forma EPS | — | — | New diluted share count | Net Income ÷ Shares |
Pro Forma Balance Sheet — M&A Context
Step 1 — Combine Both Balance Sheets
Add the acquirer’s and target’s balance sheets line by line. This is the starting point before any adjustments.
Step 2 — Apply Purchase Price Allocation
Eliminate the target’s existing shareholders’ equity (it’s been “purchased”). Write up assets to fair market value. Record goodwill for the excess of purchase price over fair value of net identifiable assets. Create deferred tax liabilities on asset write-ups.
Step 3 — Record Transaction Financing
Add new debt (term loans, bonds) to liabilities. Remove cash used for the purchase. Add new equity issued (at par plus additional paid-in capital). Record financing fees as a deferred asset (amortized over the debt term).
Step 4 — Verify the Balance Sheet Balances
Total Assets must equal Total Liabilities + Shareholders’ Equity. If they don’t, there’s an error in your adjustments. This is the critical check — a balanced pro forma balance sheet is non-negotiable.
Pro Forma Cash Flow Statement
The pro forma cash flow statement combines operating, investing, and financing activities for both companies and reflects transaction impacts. Key adjustments include higher D&A add-backs (from write-ups), changed interest payments, and debt repayment schedules. This statement is critical for assessing the combined entity’s ability to service debt, fund capex, and generate free cash flow.
Common Adjustments Summary
| Adjustment | Income Statement Impact | Balance Sheet Impact |
|---|---|---|
| Asset Write-Ups | Higher D&A (reduces net income) | Higher PP&E and intangibles, deferred tax liability |
| New Acquisition Debt | Higher interest expense | Higher long-term debt, financing fees as asset |
| Cash Used | Lost interest income | Lower cash and equivalents |
| Shares Issued | Higher share count → lower EPS | Higher common stock + APIC |
| Cost Synergies | Lower operating expenses | No direct impact (indirect via retained earnings) |
| Eliminate Target Equity | No income statement impact | Remove target’s equity, replace with goodwill + adjustments |
| Transaction Fees | One-time expense or capitalized | Reduce cash or capitalize into goodwill |
Key Takeaways
- Pro forma financials show “what if” — the combined entity’s finances as if the transaction already occurred.
- In M&A, combine both P&Ls and balance sheets, then apply purchase accounting, financing, and synergy adjustments.
- The pro forma balance sheet must balance — assets = liabilities + equity after all adjustments.
- Eliminate the target’s existing equity and replace it with goodwill and fair value adjustments.
- Present at least two years of pro forma projections to show both the integration transition and the run-rate picture.
Frequently Asked Questions
What is the difference between pro forma and GAAP financial statements?
GAAP statements follow standardized accounting rules and reflect actual historical results. Pro forma statements are hypothetical — they adjust historical financials for a proposed transaction or event. Pro forma is “as-if” reporting. Public companies must clearly label pro forma figures and reconcile them to GAAP in SEC filings.
How do I handle different fiscal year ends in a merger?
If the acquirer and target have different fiscal year ends, calendarize one set of financials to match the other. For example, if the acquirer uses December year-end and the target uses September, create a December-ending target P&L by combining the last quarter of fiscal 2024 and the first three quarters of fiscal 2025. This ensures the pro forma is apples-to-apples.
Should I include one-time transaction costs in pro forma statements?
In your full model, yes — show them separately as a non-recurring adjustment. For the pro forma P&L used in accretion/dilution analysis, most analysts exclude one-time costs and focus on the run-rate picture. In SEC filings, one-time costs must be included but are typically broken out for clarity.
How are pro forma statements used in an IPO?
Pre-IPO companies present pro forma financials in the S-1 filing to show what financials would look like after the offering — incorporating the use of IPO proceeds (debt paydown, cash on hand), the new share count, and any pre-IPO restructuring. This gives investors the post-IPO financial picture.
What’s the relationship between pro forma statements and the three-statement model?
A three-statement model projects standalone financials forward. Pro forma statements layer transaction adjustments on top of those projections. The three-statement model is the foundation — pro forma is the “what changes” overlay. In practice, bankers often build the three-statement model first for both companies, then combine them with adjustments to create the pro forma output.
