How to Read Company Financial Statements for Investing

Reading financial statements is the fundamental skill that separates real investors from speculators. While it may seem intimidating at first, the core concepts are simpler than most people think. You do not need an accounting degree -- you need to understand what matters and what to ignore.

Warren Buffett reads hundreds of annual reports every year and has done so for over six decades. He describes financial statements as the language of business, and like any language, it becomes natural with practice. Buffett focuses on three financial statements: the income statement (how much the company earns), the balance sheet (what the company owns and owes), and the cash flow statement (how cash actually moves through the business). Of these three, Buffett considers the cash flow statement the most important because "earnings can be manipulated, but cash is cash."

The income statement tells you whether the business is profitable and how those profits are trending. Buffett looks for consistent revenue growth, stable or expanding profit margins, and growing earnings per share over 5-10 year periods. He avoids companies with volatile earnings because unpredictability makes it impossible to estimate intrinsic value with any confidence. The key numbers to examine are revenue growth rate, gross margin, operating margin, and net income margin.

The balance sheet reveals the financial strength of the company. Charlie Munger pays particular attention to the debt-to-equity ratio. Companies with low debt have more flexibility during economic downturns and are less likely to face financial distress. Buffett looks for companies with high return on equity (ROE) -- ideally above 15% consistently -- because this indicates the business generates strong profits relative to shareholder investment. He also examines working capital (current assets minus current liabilities) to ensure the company can meet its short-term obligations.

The cash flow statement is where the truth lives. Benjamin Graham taught that the difference between reported earnings and actual cash flow is one of the most important things an investor can examine. Companies can show growing earnings while actually burning cash through aggressive accounting practices. Free cash flow -- operating cash flow minus capital expenditures -- is the real profit that a company generates. Buffett calls free cash flow "owner earnings" and considers it the truest measure of a company's economic value.

Howard Marks emphasizes that financial statements should be read comparatively, not in isolation. Compare the company's metrics to its competitors, to its own historical performance, and to the industry averages. A 20% profit margin means very different things in software (where it might be below average) versus retail (where it would be exceptional). Context transforms raw numbers into genuine insight.
