Earnings

Quick Definition

Earnings are a company's net profit, calculated as total revenue minus all expenses, taxes, interest, and costs. When divided by the number of shares outstanding, earnings become earnings per share (EPS), the number that drives stock prices more than any other metric. Companies report earnings quarterly, and these reports move markets instantly.

What It Means

Earnings are the bottom line. They represent what is left over after a company has paid for everything it needs to operate: inventory, salaries, rent, research, marketing, interest on debt, and taxes. If revenue is the top line (what came in), earnings are the bottom line (what stayed). Investors care about earnings because they represent the profit that can be reinvested in the business, paid out as dividends, or used to buy back shares.

The stock market is obsessed with earnings. Every quarter, publicly traded companies release earnings reports, and analysts compare the actual results to their estimates. When a company beats expectations, the stock often jumps. When it misses, the stock often falls. This reaction happens because stock prices are built on expectations of future earnings. A company does not need to have high earnings to have a high stock price, but it needs to deliver earnings that meet or exceed what investors expect.

In August 2026, the S&P 500 traded at a trailing price-to-earnings (P/E) ratio of about 27 and a forward P/E of about 20.0, according to FactSet. The forward P/E was above the 5-year average of 19.9 and the 10-year average of 19.0. The trailing 12-month earnings for the S&P 500 were approximately $276 per share, while forward 12-month earnings estimates were about $374 per share. This gap between trailing and forward earnings reflects expected earnings growth of roughly 36 percent, driven by strong corporate profitability and expanding margins.

Earnings growth has been remarkable in recent years. According to Yardeni Research, S&P 500 forward earnings grew 24.9 percent year-to-date through August 2026, while the S&P 500 index itself rose 12.1 percent. This means earnings are growing twice as fast as stock prices, which has actually pushed the forward P/E down by about 10 percent since the start of the year. BNY noted that net margins are well above their long-term historical averages, reflecting improved operating efficiency and resilient business models.

How It Works

The Earnings Calculation

Earnings are calculated on the income statement, which follows this structure:

1. Revenue (total sales)
2. Minus Cost of Goods Sold (COGS) = Gross Profit
3. Minus Operating Expenses (SG&A, R&D, depreciation) = Operating Income (EBIT)
4. Minus Interest Expense = Pre-Tax Income
5. Minus Taxes = Net Income (Earnings)

Earnings Per Share (EPS)

EPS is the most common way to express earnings. It divides net income by the weighted average number of shares outstanding:

EPS = Net Income / Shares Outstanding

For example, if a company has $1 billion in net income and 500 million shares outstanding, its EPS is $2.00. There are two versions of EPS:

• Basic EPS: Uses actual shares outstanding
• Diluted EPS: Includes all potential shares from stock options, RSUs, and convertible bonds. Diluted EPS is always lower than basic EPS and is the number most analysts use.

GAAP vs. Non-GAAP Earnings

Companies report two versions of earnings:

• GAAP earnings: Calculated according to Generally Accepted Accounting Principles. These are the official, audited numbers required by the SEC.
• Non-GAAP earnings: Adjusted by management to exclude one-time charges, stock-based compensation, restructuring costs, and other items they consider non-recurring. Non-GAAP earnings are almost always higher than GAAP earnings.

The gap between GAAP and non-GAAP earnings has widened over time. According to FactSet, the average S&P 500 company's non-GAAP EPS was about 15 to 20 percent higher than its GAAP EPS in recent years. Investors should look at both numbers and understand what adjustments management is making. The SEC requires companies to reconcile non-GAAP measures to their GAAP equivalents.

How Earnings Move Stock Prices

Stock prices are driven by the relationship between actual earnings and expected earnings. Analysts publish earnings estimates before each quarterly report. When the actual number comes out:

The reaction also depends on guidance (management's forecast for future quarters). A company can beat current earnings but lower its guidance, causing the stock to fall. Conversely, a company can miss earnings but raise guidance, causing the stock to rise.

Real-World Examples

Example 1: Reading an Earnings Report

A technology company reports the following quarterly results:

Analysts expected EPS of $1.80, so the company beat by $0.05 (2.8 percent). Revenue beat expectations of $24.5 billion. The company also raised its full-year guidance. The stock likely rises on this report because both earnings and revenue beat estimates, margins expanded, and guidance improved.

Example 2: GAAP vs. Non-GAAP

A company reports the following:

The $300 million gap comes from:

• $150M stock-based compensation (a real cost that dilutes shareholders)
• $100M restructuring charge (layoffs and office closures)
• $50M amortization of acquired intangibles

An investor needs to decide which number to trust. Stock-based compensation is a real economic cost, even though it does not involve cash. Restructuring charges may be truly one-time or may recur every few years. Amortization of intangibles is a non-cash charge from past acquisitions. Most value investors focus on GAAP earnings or carefully adjusted non-GAAP earnings that only exclude genuinely non-recurring items.

Example 3: S&P 500 Earnings in 2026

The S&P 500's aggregate earnings tell the story of the overall market. As of August 2026:

The market is trading at a forward P/E of 20.0, slightly above its 5-year average. However, earnings are growing so fast that the forward P/E has actually declined this year despite rising stock prices. This suggests that the market's gains are being driven by earnings growth rather than valuation expansion. Read our guide on how the stock market actually works for more on this dynamic.

Key Points to Remember

• Earnings are net profit: revenue minus all expenses, interest, and taxes. EPS divides earnings by shares outstanding.
• Companies report earnings quarterly. The market reacts to whether results beat, meet, or miss analyst estimates, plus management's guidance.
• GAAP earnings follow strict accounting rules. Non-GAAP earnings exclude items management deems non-recurring. Non-GAAP is almost always higher. Always check the reconciliation.
• In August 2026, the S&P 500 traded at a forward P/E of about 20.0, above the 10-year average of 19.0. Trailing earnings were about $276 per share, and forward earnings were about $374.
• Earnings growth has outpaced stock price growth in 2026, with forward earnings up 24.9 percent versus a 12.1 percent index gain year-to-date.
• Diluted EPS accounts for all potential shares from options and convertibles. It is the more conservative and widely used measure.

Common Mistakes to Avoid

• Focusing only on the earnings beat: Beating estimates by a penny does not mean the business is healthy. Look at revenue growth, margin trends, cash flow, and guidance. A company can beat earnings by cutting costs (layoffs, reduced R&D) while revenue declines, which is not sustainable.
• Ignoring the gap between GAAP and non-GAAP: Some companies exclude stock-based compensation, which is a real cost. Over time, these exclusions can make non-GAAP earnings look far better than the economic reality. Always compare GAAP and non-GAAP and understand the adjustments.
• Extrapolating one quarter into a trend: One strong or weak quarter does not define a company's trajectory. Look at multiple quarters and years to identify trends. A single quarter can be distorted by one-time events, tax changes, or accounting adjustments.
• Confusing earnings with cash flow: Earnings include non-cash items like depreciation and amortization. A company can report positive earnings while burning cash, or report losses while generating cash. Always check free cash flow alongside earnings. Read about free cash flow for the difference.
• Ignoring share count changes: Buybacks reduce shares outstanding, which boosts EPS even if net income is flat. A company can show EPS growth of 10 percent while net income is flat, purely from buybacks. Check both net income growth and EPS growth.
• Trading on earnings without understanding expectations: The market moves on surprises, not absolute numbers. A company reporting $2.00 EPS might crash if analysts expected $2.20, while a company reporting $1.00 EPS might surge if analysts expected $0.80. Always know the consensus estimate before earnings season.

Related Concepts

Earnings are the foundation of stock valuation. The price-to-earnings ratio (P/E ratio) compares stock price to EPS. Earnings yield inverts the P/E ratio to compare stock returns to bond yields. Revenue is the top line that feeds into earnings. Free cash flow is a cash-based alternative to earnings that excludes non-cash items. Dividends are paid out of earnings, and the dividend payout ratio shows what percentage of earnings is distributed. Earnings are reported on the income statement, one of the three main financial statements. Fundamental analysis uses earnings to estimate intrinsic value.

Frequently Asked Questions

Q: What is the difference between earnings and revenue? A: Revenue is the total amount of money a company brings in from sales before any expenses. Earnings (net income) are what is left after subtracting all costs, including COGS, operating expenses, interest, and taxes. A company can have high revenue and low earnings if its costs are high, or low revenue and high earnings if its margins are strong.

Q: How often do companies report earnings? A: Publicly traded companies in the US report earnings quarterly (four times per year) in filings called 10-Q reports, plus an annual report called the 10-K. Quarterly reports are filed within 40 to 45 days of quarter-end, and annual reports within 60 to 90 days of year-end. Companies also issue earnings press releases and hold earnings calls with analysts.

Q: Why do stocks sometimes fall after a company beats earnings estimates? A: The market prices in expectations before the report. If a company beats estimates but raises guidance less than expected, or signals slowing growth in future quarters, the stock can fall despite the beat. The market is forward-looking, so current earnings matter less than what management says about the future.

Q: Are non-GAAP earnings reliable? A: Non-GAAP earnings can be useful if the adjustments are genuinely non-recurring (like a one-time legal settlement). However, many companies exclude recurring costs like stock-based compensation, which inflates the reported earnings. The SEC requires companies to reconcile non-GAAP to GAAP and prohibits misleading presentations. Always review the reconciliation.

Q: What is a good earnings growth rate? A: It depends on the company and industry. For the S&P 500 overall, long-term earnings growth has averaged about 7 to 8 percent annually. In 2026, forward earnings growth was running at about 25 to 36 percent, which is well above average and driven by expanding margins. For individual companies, growth rates of 10 to 15 percent are considered strong for mature companies, while growth stocks may target 20 percent or higher.
