Capital Expenditure (CapEx)
Quick Definition
Funds spent by a company to acquire, upgrade, or maintain physical assets like property, buildings, equipment, or technology.
Key Takeaways
- Money spent on long-term physical assets that are capitalized on the balance sheet
- Maintenance CapEx maintains existing operations; growth CapEx expands capacity
- Free cash flow = Operating cash flow minus CapEx
- Capital-intensive businesses require more CapEx relative to revenue
- Compare CapEx to depreciation to assess whether a company is investing for growth
What Is Capital Expenditure (CapEx)?
Capital expenditure (CapEx) represents the money a company spends on acquiring, improving, or maintaining long-term physical assets. These investments include purchasing new equipment, building factories, upgrading technology systems, and buying land or buildings. CapEx appears on the cash flow statement under "investing activities" and is capitalized on the balance sheet rather than expensed immediately on the income statement.
CapEx is crucial for fundamental analysis because it reveals how much a company is investing in its future productive capacity. There are two types: maintenance CapEx (spending required just to keep existing assets functioning) and growth CapEx (spending to expand capacity or enter new markets). The distinction matters enormously — maintenance CapEx is essentially a required cost, while growth CapEx is discretionary and hopefully value-creating.
Free cash flow, one of the most important metrics in valuation, is calculated as operating cash flow minus CapEx. Companies with high CapEx requirements (capital-intensive businesses like airlines, utilities, and manufacturers) typically generate lower free cash flow relative to their earnings, while asset-light businesses (software, consulting, financial services) convert a higher percentage of earnings into free cash flow. Warren Buffett has historically preferred businesses with low capital requirements, as they can grow without constantly reinvesting large sums. When analyzing CapEx, compare it to depreciation — if CapEx consistently exceeds depreciation, the company is investing for growth; if they're roughly equal, the company is mainly maintaining existing assets.
Capital Expenditure (CapEx) Example
- 1Amazon spent over $50 billion in CapEx in 2023, primarily on AWS data centers and fulfillment infrastructure.
- 2A software company might have CapEx of only 3-5% of revenue, while an oil company might spend 20-30%.
- 3Tesla's massive CapEx for Gigafactories eventually enabled economies of scale that reduced per-unit costs.
