Earnings per share (EPS) is one of the most widely used financial metrics in investing. It helps investors understand how profitable a company is on a per-share basis and plays a key role in stock valuation and earnings analysis.
EPS shows how much profit a company earns per share of common stock, making it easier to compare performance across companies.
The EPS calculation depends on accurate net income and weighted average shares outstanding, not just total shares at year-end.
EPS should generally be used alongside other metrics, such as cash flow and revenue growth, for a complete picture of financial health.
Earnings per share (EPS) measures how much profit a company generates per outstanding share of common stock. It represents the portion of a company’s earnings allocated to each share owned by investors.
EPS helps investors understand:
Profitability on a per-share basis
How a company’s performance changes over time
How one company compares to others in the same industry
Because EPS standardizes earnings across share counts, it’s often especially useful for comparisons.
EPS is commonly reported on:
Income statements
Quarterly and annual earnings reports
Financial news websites and stock screeners
Most public companies report both basic and diluted EPS.
The standard EPS formula is:
EPS = (Net income − preferred dividends) ÷ weighted average shares outstanding
EPS measures earnings available to common shareholders. Since preferred shareholders have priority claims on dividends, their dividends are subtracted before calculating earnings attributable to common stock.
Companies rarely have the same number of shares outstanding all year. The weighted average accounts for changes caused by:
Stock issuance
Share buybacks
Stock splits
Using a weighted average can prevent EPS from being distorted by timing differences.
Locate net income on the income statement. This figure generally appears at the bottom and reflects earnings after taxes and expenses.
If the company has preferred stock, subtract preferred dividends. Many companies do not issue preferred stock, in which case this step equals zero.
Use the weighted average number of shares outstanding over the reporting period, not just the ending share count.
Divide earnings available to common shareholders by the weighted average shares to calculate EPS.
Let’s use the following company information as an example:
Net income: $10 million
Preferred dividends: $1 million
Weighted average shares outstanding: 5 million
Calculation:
($10 million − $1 million) ÷ 5 million = $1.80 EPS
An EPS of $1.80 means the company earned $1.80 in profit for each outstanding share of common stock during the period.
Basic EPS uses only the shares of common stock currently outstanding.
Diluted EPS includes the impact of potential additional shares issued in the form of:
Stock options
Warrants
Convertible bonds or preferred stock
Diluted EPS reflects the potential impact on earnings per share if all convertible securities were exercised.
Public companies typically report:
Basic EPS
Diluted EPS
These figures usually appear near the bottom of the income statement.
EPS can be reported as:
Quarterly EPS: performance for a single quarter
Trailing twelve months (TTM) EPS: combined results from the last four quarters
TTM EPS is often used for valuation ratios.
Consistent EPS growth can reflect improving profitability, though it should be evaluated alongside other financial indicators.
EPS is commonly used in valuation metrics such as the price-to-earnings (P/E) ratio, which compares stock price to earnings.
EPS allows investors to compare companies of different sizes and track performance over time.
EPS can increase without real business improvement through:
Share buybacks that reduce share count
Accounting changes that affect reported earnings
EPS is based on accounting profit, not actual cash generated by the business.
Capital-intensive industries often have different EPS profiles than asset-light businesses, making cross-industry comparisons less meaningful.
Net income shows total profit while EPS shows profit per share.
Free cash flow per share focuses on actual cash generation rather than accounting earnings.
EPS is more shareholder focused. Earnings before interest, taxes, depreciation, and amortization (EBITDA) focuses more on a company’s profitability from its daily operations.
This may overstate earnings available to common shareholders.
Using end-of-period shares instead of weighted average shares may distort EPS.
EPS should not replace broader financial analysis.
EPS is a foundational metric for evaluating company profitability and stock valuation, but it often works best when used in context. Understanding how EPS is calculated along with its limitations helps investors make more informed decisions.
It’s also important to keep in mind that investments can go down as well as up in value. Past performance and earnings growth do not guarantee future results.

Divide earnings available to common shareholders by the weighted average number of shares outstanding.
There’s no universal “good” EPS — it depends on the company, industry, and growth trends.
A higher EPS may indicate stronger profitability, but context matters. Investors often consider growth trends, industry conditions, and overall financial health.
Reporting both can show current earnings per share and potential dilution risk for shareholders.
