Financial Modeling & Valuation
Module 1: Financial Statement Analysis for Modeling
Module Overview
Before you can build a financial model, you need to understand the raw materials. Financial statements aren't just historical records—they're the foundation for every projection you'll make. In this module, you'll learn to read financial statements through a modeler's lens, focusing on the relationships and drivers that make forecasting possible.
Learning Objectives:
By the end of this module, you will be able to:
- Analyze financial statements to identify modeling drivers
- Understand the linkages between the three financial statements
- Calculate key ratios and metrics used in financial modeling
- Normalize historical financials for comparability
- Identify the assumptions needed for a 3-statement model
Estimated Time: 4-5 hours
1.1 The Modeler's Perspective
Thinking Like a Modeler
When accountants look at financial statements, they ask: "Are these accurate?" When analysts look at financial statements, they ask: "What does this tell us about the company?" When modelers look at financial statements, they ask: "How can I project this forward?"
The modeler's questions:
- What drives this line item?
- How does it relate to other items?
- What assumptions would I need to forecast it?
- How has it behaved historically?
- What's a reasonable growth rate or margin?
This mindset shift is crucial. You're not just reading history—you're extracting the patterns and relationships that will power your projections.
The Three Statements Revisited
You know the three financial statements. Now let's understand them as a modeler does:
Income Statement
- Measures performance over a period
- Key outputs: Revenue, Gross Profit, Operating Income, Net Income
- Modeler's focus: What drives revenue? How stable are margins?
Balance Sheet
- Snapshot of position at a point in time
- Key outputs: Assets, Liabilities, Equity
- Modeler's focus: What's the working capital pattern? How much CapEx is needed?
Cash Flow Statement
- Explains changes in cash
- Key outputs: Operating, Investing, Financing cash flows
- Modeler's focus: What's the cash conversion? How is the company funded?
The Critical Insight: These statements aren't independent. They're deeply interconnected. Understand the linkages, and you can build a model where one change cascades correctly through all three statements.
1.2 The Linkages Between Statements
How the Statements Connect
Understanding statement linkages is fundamental to financial modeling. Here's how they interconnect:
Income Statement → Balance Sheet
Net Income → Retained Earnings (Equity)
Depreciation Expense → Accumulated Depreciation (PP&E)
Interest Expense → Accrued Interest (Current Liabilities)
Balance Sheet → Cash Flow Statement
Change in Working Capital → Operating Cash Flow
Change in PP&E (net of depreciation) → Investing Cash Flow
Change in Debt → Financing Cash Flow
Change in Equity → Financing Cash Flow
Cash Flow Statement → Balance Sheet
Net Change in Cash → Cash on Balance Sheet
The Circular Reference: Interest Expense
Here's where it gets interesting. Interest expense depends on debt levels. But debt levels depend on cash flow. And cash flow depends on interest expense.
This creates a circular reference:
- Interest expense reduces net income
- Lower net income reduces cash flow
- Lower cash flow may require more debt
- More debt increases interest expense
- Return to step 1
In Excel, you'll handle this with iterative calculations. For now, understand that this circularity is why building integrated models requires careful thought.
The Balancing Act
The balance sheet must balance: Assets = Liabilities + Equity
In a financial model, you typically:
- Project all asset items except cash
- Project all liability items
- Project equity (including retained earnings from net income)
- Cash becomes the "plug" that balances the balance sheet
Alternatively, some models use debt as the plug (the "revolver" approach), where the company draws or repays a credit facility to balance.
Key Insight: If your balance sheet doesn't balance, something is wrong. This is your primary error-check in financial modeling.
1.3 Income Statement Drivers
Revenue Drivers
Revenue is the most important—and often most uncertain—projection. Different businesses require different approaches:
Volume × Price
Revenue = Units Sold × Price per Unit
Best for: Product companies, manufacturing, retail
Example:
Year 1: 1,000,000 units × $50 = $50,000,000
Year 2: 1,100,000 units × $52 = $57,200,000
Growth: 14.4%
Same-Store Growth + New Stores
Revenue = Existing Store Revenue × (1 + Same-Store Growth) + New Store Revenue
Best for: Retail chains, restaurant groups
Recurring + New Business
Revenue = Beginning ARR × (1 - Churn) + New ARR
Best for: SaaS companies, subscription businesses
Market Size × Market Share
Revenue = Total Addressable Market × Market Share
Best for: Market analysis, competitive positioning
Segment Build-Up
Revenue = Segment A Revenue + Segment B Revenue + Segment C Revenue
Best for: Diversified companies, conglomerates
Cost Drivers
Cost of Goods Sold (COGS)
COGS typically relates to revenue:
COGS = Revenue × COGS %
Or for more detail:
COGS = Direct Materials + Direct Labor + Manufacturing Overhead
Key metrics:
- Gross Margin = (Revenue - COGS) / Revenue
- COGS as % of Revenue
Operating Expenses
Operating expenses often have fixed and variable components:
Selling, General & Administrative (SG&A)
SG&A = Fixed Costs + (Variable % × Revenue)
Research & Development (R&D)
- Often modeled as % of revenue
- Or as headcount × cost per employee
Depreciation & Amortization
- Modeled from the asset base
- Depreciation = PP&E / Average Useful Life
- Or use detailed depreciation schedule
Margins to Watch
Gross Margin
Gross Margin = (Revenue - COGS) / Revenue
- Reflects pricing power and cost efficiency
- Typically stable for mature companies
- Watch for trends and industry comparisons
Operating Margin (EBIT Margin)
Operating Margin = Operating Income / Revenue
- Shows operational efficiency
- Excludes financing effects
- Key for comparing companies with different capital structures
EBITDA Margin
EBITDA Margin = EBITDA / Revenue
- Approximates cash operating margin
- Popular in leveraged finance
- Useful for capital-intensive industries
Net Margin
Net Margin = Net Income / Revenue
- Bottom-line profitability
- Includes all costs including interest and taxes
- Varies significantly with capital structure
1.4 Balance Sheet Drivers
Working Capital
Working capital items are typically driven by revenue or COGS:
Accounts Receivable
A/R = Revenue × (Days Sales Outstanding / 365)
Or:
A/R Turnover = Revenue / Average A/R
Inventory
Inventory = COGS × (Days Inventory Outstanding / 365)
Or:
Inventory Turnover = COGS / Average Inventory
Accounts Payable
A/P = COGS × (Days Payable Outstanding / 365)
Or:
A/P Turnover = COGS / Average A/P
Net Working Capital
NWC = Current Assets - Current Liabilities
(Excluding cash and debt)
The Cash Conversion Cycle
CCC = DSO + DIO - DPO
This tells you how long cash is tied up in operations. Lower is better.
Capital Expenditures and PP&E
Capital Expenditures (CapEx)
CapEx can be modeled several ways:
As % of Revenue:
CapEx = Revenue × CapEx %
Maintenance vs. Growth:
CapEx = Maintenance CapEx + Growth CapEx
Maintenance CapEx ≈ Depreciation
Growth CapEx = function of expansion plans
As % of Depreciation:
CapEx = Depreciation × CapEx/D&A ratio
PP&E Roll-Forward
Ending PP&E = Beginning PP&E + CapEx - Depreciation
This is a critical schedule in your model. Get it right, and your balance sheet will reconcile. Get it wrong, and nothing will balance.
Debt and Interest
Debt Schedule
A proper debt schedule tracks:
- Beginning balance
- New borrowings
- Repayments (scheduled and voluntary)
- Ending balance
- Interest expense
Interest Expense = Average Debt Balance × Interest Rate
Or for more precision:
Interest Expense = Beginning Debt × Interest Rate
(This avoids circularity but is less accurate)
Types of Debt to Model:
- Revolving credit facility (the "revolver")
- Term loans
- Senior notes/bonds
- Subordinated debt
- Capital leases
Each may have different interest rates and repayment terms.
1.5 Cash Flow Statement Drivers
Operating Cash Flow
The cash flow statement starts with net income and adjusts for non-cash items and working capital changes.
Non-Cash Adjustments:
- Add back Depreciation & Amortization
- Add back Stock-Based Compensation
- Adjust for Deferred Taxes
- Add back other non-cash charges
Working Capital Adjustments:
- Decrease in A/R = Cash Inflow
- Increase in A/R = Cash Outflow
- Decrease in Inventory = Cash Inflow
- Increase in Inventory = Cash Outflow
- Increase in A/P = Cash Inflow
- Decrease in A/P = Cash Outflow
Key Formula:
Operating Cash Flow = Net Income + Non-Cash Charges - Increase in Working Capital
Investing Cash Flow
Components:
- Capital Expenditures (outflow)
- Acquisitions (outflow)
- Asset Sales (inflow)
- Investment Purchases (outflow)
- Investment Sales (inflow)
In most models:
Investing Cash Flow = -CapEx + Asset Sales - Acquisitions
Financing Cash Flow
Components:
- Debt Issuance (inflow)
- Debt Repayment (outflow)
- Equity Issuance (inflow)
- Share Repurchases (outflow)
- Dividend Payments (outflow)
In models:
Financing Cash Flow = ΔDebt + ΔEquity - Dividends - Buybacks
Free Cash Flow
Free Cash Flow to Firm (FCFF)
FCFF = EBIT × (1 - Tax Rate) + D&A - CapEx - ΔNWC
This is the cash available to all capital providers (debt and equity).
Free Cash Flow to Equity (FCFE)
FCFE = Net Income + D&A - CapEx - ΔNWC - Net Debt Repayment
This is the cash available to equity holders after debt service.
Why It Matters: FCFF is used in DCF valuation (discounted at WACC). FCFE is used for equity valuation (discounted at cost of equity).
1.6 Normalizing Historical Financials
Why Normalize?
Historical financials contain noise:
- One-time charges
- Non-recurring gains/losses
- Accounting changes
- Unusual events
Before modeling, you need to understand the underlying performance.
Common Adjustments
Non-Recurring Items
- Restructuring charges
- Litigation settlements
- Impairment charges
- Gains/losses on asset sales
- Natural disaster impacts
Accounting Adjustments
- Operating lease adjustments (pre-ASC 842)
- Stock option expense normalization
- Pension adjustments
- Changes in accounting policies
Pro Forma Adjustments
- Full-year impact of acquisitions
- Full-year impact of divestitures
- Removing discontinued operations
Example Normalization
Reported EBITDA: $100M
Adjustments:
- Add back: Restructuring charges $5M
- Add back: Litigation settlement $3M
- Remove: Gain on asset sale ($2M)
- Add back: One-time consulting fees $1M
Adjusted EBITDA: $107M
This adjusted figure is what you'd use for forecasting and valuation multiples.
Red Flags in Normalization
Be skeptical when companies:
- Add back "non-recurring" items every year
- Have adjustments that always increase earnings
- Provide minimal detail on adjustments
- Use aggressive definitions of "adjusted" metrics
Rule of thumb: If an expense recurs, it's not non-recurring.
