Neither measure is automatically more important. Compare them for matching periods, then use margins, operating cash flow, share counts, and the definition of “earnings” to understand what is driving the difference.
Revenue and earnings measure different things
Revenue is the top line: sales recognized during a reporting period. It is not necessarily the cash collected in that period. Earnings are what remains after the income statement accounts for costs and expenses, interest, and taxes. The SEC’s guide to reading company financial statements explains how an income statement starts with sales and deducts costs and expenses to arrive at net earnings.

“Earnings” can refer to several measures, so name the one you are comparing. Net income is different from operating income, adjusted earnings, and earnings per share (EPS). EPS divides net income by outstanding shares, so a change in share count can make EPS growth diverge from net income growth.

For each measure, compare the current period with the equivalent prior period: a quarter with the same quarter a year earlier, or a full year with the prior full year. Keep the accounting basis consistent and use continuing operations when available.

- 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 can be undefined or misleading. Describe the direction and scale of the change instead of forcing a percentage that obscures the starting point.
What the gap between growth rates can tell you
If earnings grow faster than revenue, the company may have improved margins, sold more higher-margin products or services, reduced costs, or benefited from changes in interest or tax expense. If you are comparing EPS, a lower share count can also boost per-share growth. These are explanations to investigate, not conclusions the growth rates prove.

If revenue grows faster than earnings—or revenue rises while earnings fall—profitability may be under pressure. Possible causes include weaker margins, higher operating costs, spending on an acquisition or launch, increased interest or taxes, or a one-time charge. The growth-rate comparison flags a question; it does not identify the cause by itself.

Margins show how much profit a company keeps at different stages of the income statement. Gross margin can help reveal changes in production or service-delivery economics; operating margin shows the share of revenue remaining as operating income. The SEC defines operating margin as income from operations divided by net revenues, a measure of the portion of each sales dollar that is profit at that stage.
Rank #3
Compare gross and operating margins over time to see where improvement or pressure appears. Ratios differ across industries, so compare a company with its own history and with similar businesses rather than applying one universal target. The SEC’s financial statement guide also cautions that desirable ratios vary by industry.
Put net income beside operating cash flow
Net income is an accounting measure; operating cash flow tracks cash inflows and outflows from operations. For most companies, the cash flow statement reconciles net income to cash from operating activities by adjusting for noncash items and changes in operating assets and liabilities.
Rank #4
When earnings rise but operating cash flow is weak or falling, investigate working-capital changes, noncash gains, and whether customers are paying on time. That divergence merits attention, but it does not by itself prove that earnings are poor quality.
Separate GAAP results, adjusted measures, and EPS
Start with reported net income and diluted EPS, clearly labeled. If a company also reports adjusted earnings or adjusted EPS, read its reconciliation: identify the expenses or gains excluded, related tax effects, and the share count used. Adjusted measures are not interchangeable with GAAP results, and similarly named non-GAAP measures may be calculated differently across companies. One recent SEC-filed issuer release explicitly warns that its non-GAAP measures are not substitutes for GAAP measures and may not be comparable with similarly titled measures at other companies.

FactSet Research Systems’ fiscal 2026 fourth-quarter release is a useful company-specific illustration, not a market benchmark. FactSet reported year-over-year revenue growth of 6.3%, while net income fell 21.1%. Adjusted net income rose 4.1%; diluted EPS fell 15.4%, while adjusted diluted EPS rose 11.6%. The company attributed the GAAP EPS decline mainly to higher operating expenses, including non-recurring items, and a prior-year divestiture gain, partly offset by revenue growth and a lower share count. Its release also cautions that non-GAAP information is not a substitute for GAAP financial information. Read FactSet’s fiscal 2026 fourth-quarter results.

- Compare revenue growth and net income growth over the same periods, using continuing operations when available.
- Review gross and operating margin trends to locate changes in profitability.
- Compare operating cash flow with net income and investigate meaningful divergence.
- If discussing per-share growth, check diluted EPS alongside diluted share count.
- Compare GAAP results with adjusted measures only after reading the company’s reconciliation and the reason for each adjustment.
- Use organic, constant-currency, or acquisition-adjusted growth only when the company defines the measure and provides comparable reconciliations; definitions can differ.
There is no universal ideal gap between earnings growth and revenue growth. The SEC’s guidance notes that ratios vary by industry, and the figures must be interpreted in the context of the company, period, and accounting measures being compared.
