Neither revenue growth nor earnings growth is automatically the better sign. Revenue shows how sales are changing; earnings show what remains after costs and other income-statement items. Compare both over matching periods, then use margins, operating cash flow, share count and the definition of earnings to understand what the gap means.

Revenue, earnings and EPS measure different things

Revenue is sales recognized during a reporting period. It is not necessarily cash collected during that period. Earnings can refer to several measures, so specify which one you mean; a common starting point is net income, or net earnings, after costs, expenses, interest and taxes. The SEC’s beginner’s guide to financial statements explains how an income statement moves from sales through deductions to net earnings.

Earnings per share (EPS) divides net income by the number of outstanding shares. As a result, EPS growth can differ from net income growth when the share count changes. A claim that “earnings grew” is incomplete unless it identifies whether it refers to net income, operating income, adjusted earnings or EPS.

How to calculate growth fairly

Compare like with like: a quarter with the same quarter a year earlier, or a full year with the prior full year. Use the same accounting basis and, where available, compare continuing operations rather than mixing them with discontinued businesses.

  • Revenue growth: (current-period revenue − comparable prior-period revenue) ÷ comparable prior-period revenue.
  • Earnings growth: (current-period earnings − comparable prior-period earnings) ÷ comparable prior-period earnings.

If prior-period earnings were zero or negative, a percentage growth rate may be undefined or misleading. Describe the change in amount and direction instead of presenting a percentage that suggests a meaningful rate.

What a gap between revenue and earnings growth can signal

The gap is a prompt to investigate, not a verdict on the business. Earnings growing faster than revenue may reflect better margins, a mix shift toward higher-margin products or customers, lower costs, changes in interest or tax expense, or—when the comparison is EPS—a lower share count. Revenue growing faster than earnings may reflect margin pressure, higher operating costs, investment in a launch or acquisition, higher interest or taxes, or one-off charges. Growth rates alone do not establish which explanation applies.

Start with gross and operating margins

Margins help locate where profitability is changing. Gross margin shows profit after the direct costs of goods or services; operating margin measures income from operations divided by net revenues. The SEC’s guide describes operating margin as the portion of each sales dollar that remains as operating income. Compare the company with its own history and with similar businesses: desirable ratios vary by industry, so there is no universal margin target.

Check operating cash flow against net income

The cash flow statement reports cash inflows and outflows. For most companies, it reconciles net income to cash from operating activities by adjusting for noncash items and changes in operating assets and liabilities. If earnings rise while operating cash flow is weak or falling, investigate working capital, noncash gains and collections. That divergence merits attention but does not, by itself, prove that earnings are poor quality.

Keep GAAP, adjusted results and per-share growth distinct

Use reported net income and diluted EPS as clearly labeled starting points. If a company also reports adjusted earnings or adjusted EPS, read its reconciliation: note the expenses or gains excluded, related tax effects and share-count basis. Adjusted measures are not interchangeable with GAAP results, and companies may calculate similarly named measures differently. A recent SEC-filed issuer release, for example, cautions that its specified non-GAAP measures are not substitutes for GAAP measures and may not be comparable with similarly titled measures from other companies.

FactSet Research Systems Inc.’s fiscal 2026 fourth-quarter release illustrates why the labels matter. For that specific quarter, FactSet reported revenue growth of 6.3% year over year, net income decline of 21.1%, adjusted net income growth of 4.1%, diluted EPS decline of 15.4% and adjusted diluted EPS growth of 11.6%. The company attributed the GAAP EPS decline mainly to higher operating expenses, including non-recurring items, and a prior-year divestiture gain; revenue growth and a lower share count partly offset those effects. These are FactSet’s figures for one quarter, not a market benchmark. Its release also says non-GAAP information is not a substitute for GAAP financial information.

A practical comparison checklist

  1. Match the periods and basis. Compare equivalent quarters or full years, use the same accounting basis, and check whether the figures include continuing operations.
  2. Compare revenue with net income. This shows whether recognized sales and bottom-line profit are moving at similar rates.
  3. Trace margin trends. Review gross and operating margins over time to see whether the change appears in product economics or later operating costs.
  4. Compare net income with operating cash flow. Look for working-capital movements, noncash items and collection patterns that help explain a divergence.
  5. Separate total earnings from per-share results. Check diluted share count before interpreting diluted EPS growth.
  6. Inspect adjusted figures. Compare them with GAAP results and read the company’s reconciliation and definitions.
  7. Qualify growth adjustments. Use organic, constant-currency or acquisition-adjusted growth only when the company defines the measure and provides comparable reconciliations; definitions can differ.

Is earnings growth more important than revenue growth?

Neither measure is sufficient on its own. Revenue growth indicates whether recognized sales are expanding; earnings growth shows how profit is changing after costs and other items. Their relationship, together with margin trends, cash generation and share-count effects, provides a more useful picture than choosing one growth rate as universally more important. SEC Chief Accountant Lynn E. Turner made a similar point about top-line trends in remarks dated May 31, 2001, while noting that the views were his own and not necessarily those of the Commission or colleagues: “Trends and growth in the top line of a company’s income statement are barometers investors use when assessing the company’s past performance and future prospects.”
