Measure returns, not just growth

A company can grow sales without improving the value of the business. It may need so much additional capital to produce each dollar of growth that the benefit to owners is limited.

Return on equity

Return on equity (ROE) = Net profit ÷ Average shareholders’ equity × 100

Suppose a company earns $1 million on average equity of $5 million. Its ROE is 20%. That seems encouraging, but ROE does not explain how much risk the company assumed to produce the result.

Imagine the company borrows heavily and uses the money to repurchase shares. Its accounting equity may shrink, causing ROE to increase even if operating performance stays unchanged. This is why high ROE must be investigated alongside leverage.

Return on invested capital

Return on invested capital (ROIC) tries to compare operating profit after tax with capital supplied for operating purposes. Different analysts use different adjustments and definitions, so comparisons need consistent methods.

Its broader lesson is straightforward: What economic profit does the business earn from the capital it requires?

Earnings per share and buybacks

Earnings per share (EPS) measures earnings attributable to each share. If total profit remains unchanged while the number of shares declines, EPS may rise because each remaining share represents a larger ownership fraction.

Buybacks can be beneficial when shares are purchased at sensible prices without harming financial flexibility. They can destroy value when funded imprudently or made at excessive valuations. Always review share counts, buyback prices and debt levels together.

Growth deserves a return test

Suppose a proposed project requires $4 million of new capital and is expected to generate $200,000 in additional annual operating profit after tax. That is a 5% illustrative return on incremental capital. Whether it creates value depends on project risk and the company’s cost of capital.

Growth that consumes capital at poor returns can make a business bigger without making it better.

Key takeaway

The strongest businesses do not merely grow—they use capital productively and maintain that performance without excessive risk.

Quick reference

• Check five-year profitability, share count and equity trends.
• Explain why ROE changed.
• Compare returns with the cost and risks of financing.
• Review whether new investments are generating useful results.
