Financial Statements Glossary

Income statement (P&L)

The income statement (also called the profit-and-loss statement, statement of operations, or statement of earnings) shows revenue, costs, and resulting profit over a defined period — typically a quarter or year. Standard structure: revenue at the top, COGS deducted to get gross profit, operating expenses deducted to get operating profit (EBIT), then interest and tax to arrive at net income. Public companies report in this order under both GAAP and IFRS.

The income statement is accrual-based — it shows revenue earned and expenses incurred regardless of when cash moved. A business can be profitable on the P&L and bleeding cash. The cash flow statement reconciles the two; reading the P&L without the cash flow statement is half the picture.

Balance sheet

The balance sheet describes the company's financial position at a single point in time — typically the last day of a quarter or year. The fundamental equation: assets equal liabilities plus equity. Assets are what the company owns or controls (cash, receivables, inventory, equipment, intangibles). Liabilities are what it owes (payables, debt, deferred revenue). Equity is the residual claim of shareholders.

Balance sheet analysis reveals capital structure (debt vs. equity), liquidity (current assets vs. current liabilities), and asset composition (heavy on tangible vs. intangible). Trends across multiple balance sheets — how working capital is changing, how debt is moving, how goodwill is accumulating from acquisitions — often tell a richer story than any single snapshot.

Cash flow statement

The cash flow statement reconciles the P&L's accrual-based net income to the actual change in cash on the balance sheet. It's organized into three sections: operating (cash from running the business), investing (cash spent on capex and acquisitions or received from divestitures), and financing (cash raised from debt or equity, or returned via debt repayment, dividends, or buybacks). The three sections sum to the change in cash.

The cash flow statement is the most reliable indicator of business health because cash is harder to manipulate than accrual earnings. A business with growing reported earnings but persistently weak operating cash flow is showing either heavy accruals (deferred revenue, capitalized costs) or deteriorating receivables — either way, a flag. Free cash flow (operating cash flow minus capex) is the most-watched derived metric.

Revenue

Revenue is the top line — value of goods or services delivered to customers in the period, recognized under accrual rules (ASC 606 in the US, IFRS 15 internationally). For a product company, revenue is recognized when the product is delivered. For a subscription business, revenue is recognized over the service period (a 12-month subscription generates 1/12 of revenue per month, even if billed upfront). For a services company, revenue is recognized as the service is delivered — sometimes via percentage of completion.

The revenue recognition rules are technical and consequential. Companies that bundle services with products, sell multi-element arrangements, or have long-term contracts deal with revenue recognition complexity that materially affects reported numbers. ASC 606 standardized this in 2018; the standardization improved comparability but the underlying rules remain intricate.

Gross profit and gross margin

Gross profit is what's left from revenue after the direct cost of producing what was sold. Gross margin is gross profit divided by revenue, expressed as a percentage. The metric isolates the unit economics of the product itself — pricing power, manufacturing efficiency, scale economics — from the company's choices about overhead, sales, and marketing.

Gross margin sets the ceiling on every other margin. A 30% gross margin business cannot be a 30% operating margin business; the math doesn't work. Industry gross margin benchmarks vary widely: software at 70-85%, hardware at 30-50%, distribution at 15-30%, services at 40-60%. See the gross margin calculator.

Operating expenses (OpEx)

Operating expenses are the costs of running the business that aren't directly tied to producing the goods or services sold — sales and marketing (S&M), research and development (R&D), and general and administrative (G&A). Each line tells a different strategic story. Heavy S&M relative to revenue indicates a sales-led growth strategy; heavy R&D indicates a product-led one; heavy G&A is usually a scale problem.

Tracking the three OpEx lines as a percentage of revenue over time is one of the cleanest reads on operating efficiency. SaaS benchmarks: S&M at 25-50% of revenue (higher in early stage), R&D at 15-30%, G&A at 8-15%. Outliers in any direction warrant explanation.

Operating income (EBIT)

Operating income (or operating profit, or EBIT) is what's left after operating expenses are deducted from gross profit. It captures the profitability of the core business — what the operations actually earned, before paying interest on debt or income tax. Operating margin (operating income / revenue) is the standard cross-company comparability metric for company-level profitability.

Net income

Net income is the bottom line of the income statement: revenue minus all expenses including COGS, operating expenses, interest, and tax. It's the figure that flows to retained earnings on the balance sheet and is the basis for earnings per share calculations. Net income includes one-time items (gains on sales, restructuring charges, impairments), which is why "adjusted" or "normalized" net income is often reported alongside.

Net income volatility is normal — tax true-ups, non-recurring items, and one-time gains/losses produce swings that don't reflect operating performance. Investors typically focus more on operating income and free cash flow for trend analysis, using net income as a closing data point rather than a primary metric.

Current vs. non-current

The balance sheet is divided between current items (expected to be settled or converted to cash within 12 months) and non-current items (longer horizon). Current assets: cash, accounts receivable, inventory, prepaid expenses. Non-current assets: PP&E, goodwill, intangibles, long-term investments. Current liabilities: accounts payable, accrued expenses, short-term debt, current portion of long-term debt, current portion of deferred revenue. Non-current liabilities: long-term debt, long-term deferred revenue, pension obligations.

The current/non-current split feeds liquidity ratios — current ratio, quick ratio — and surfaces near-term cash needs. A company with $50M of current liabilities and $30M of current assets has a working capital problem regardless of how strong its long-term balance sheet looks.

Free cash flow

Free cash flow is the cash a business generates after funding the capital investments needed to maintain or grow operations. It's the cash actually available to pay down debt, return to shareholders, or fund new initiatives. FCF is the truer measure of business performance than net income because it accounts for actual cash spent on equipment, software development, and other capex.

Two common variants: unlevered FCF (before interest payments) is the standard for enterprise-value DCF analysis; levered FCF (after interest) is what flows to equity holders. FCF margin (FCF / revenue) is the cleanest single number for cross-company profitability comparison. See the DCF calculator for the role of FCF in valuation.

Stockholders' equity

Stockholders' equity (or shareholders' equity, or book value) is what's left on the balance sheet after all liabilities are subtracted from all assets — the residual claim of shareholders. Components: paid-in capital (par value of issued shares plus additional paid-in capital from share sales), retained earnings (cumulative profits not distributed as dividends), and treasury stock (shares the company has repurchased, deducted from equity).

For early-stage companies, equity is usually small relative to market value; for mature companies with decades of retained earnings, it can be substantial. Book value per share (equity divided by shares outstanding) is one anchor for valuation but rarely the most important; market value typically exceeds book value by a wide margin for going concerns.
