Earnings per Share (EPS)
Earnings Per Share
Earnings per share (EPS) measures a company's profitability by calculating how much of its net income is allocated to each outstanding share of common stock. It serves as a key profitability ratio used by investors during fundamental analysis to evaluate a company's financial health and performance. EPS helps determine stock valuation and influences important metrics such as the price-to-earnings ratio (P/E ratio) and return on equity (ROE).
This single-share value is widely used by investors to assess a company’s profitability and compare market performance across companies. Across exchanges, any two companies likely list vastly different amounts of shares, and their profits may also have wide ranges. EPS is a simple way to account for these differences when comparing companies.
How to calculate earnings per share (EPS)
Earnings per share can be calculated using a very simple formula: net profit divided by weighted average shares outstanding. To calculate net profit, you take the company’s net income and subtract all dividend payments for that period.
Earnings per share formula
EPS = (Net Income – Dividend Payments) / Weighted Average Shares Outstanding
Net income represents the company’s total earnings after expenses and taxes. Dividend payments refer to preferred dividends paid out to shareholders. The weighted average shares outstanding reflect the average number of shares held by investors over the reporting period.
Diluted EPS formula
Diluted earnings per share accounts for convertible securities like stock options and convertible bonds that could potentially increase a company’s total number of shares. Diluted EPS reflects a more conservative view of a company’s earnings potential.
The formula for diluted EPS is:
Diluted EPS = (Net Income – Preferred Dividends + Convertible Securities) / (Weighted Average Shares Outstanding + Convertible Securities)
Adjusted EPS
Adjusted EPS excludes non-recurring expenses or one-time events to give a clearer picture of a company’s core profitability. It’s often used to assess long-term performance and remove short-term volatility.
Earnings per share calculation example
Here’s an example to compare EPS for two companies:
Company A has a net income of €6.8B, no preferred dividends, and 3.24B total weighted common shares.
- Company A EPS: 6.8/3.24 = €2.01 EPS
Company B has a net income of €19.57B, €2.11B in preferred dividends, and 10.6B total weighted common shares.
- Company B EPS: 19.57-2.11/10.6 = €1.65 EPS
Comparing EPS values helps assess which company is more profitable on a per-share basis. Additionally, trailing twelve months (TTM) EPS reflects the company’s earnings over the past 12 months, while forward EPS estimates future earnings based on analysts' projections.
Why EPS matters in stock market analysis
EPS is a widely used tool in stock market analysis to evaluate a company's profitability and investment potential. Comparing EPS with the stock price helps investors determine whether a stock is overvalued or undervalued, influencing stock valuation.
For example, the P/E ratio is calculated by dividing the stock price by EPS, providing insight into how much investors are willing to pay for each dollar of earnings. A higher EPS typically signals strong profitability, but it should be analyzed alongside other metrics like ROE and market capitalization for a more complete picture.
Limitations of EPS as a performance indicator
While EPS is a useful measure of profitability, it has limitations. It does not account for factors like debt levels, cash flow sustainability, or capital structure. A company can inflate EPS through share buybacks, which reduce the number of shares outstanding without improving actual profitability.
EPS also overlooks the cost of capital and future growth potential, which are critical in investment decision-making. Comparing EPS with other metrics such as ROE, P/E ratio, and adjusted EPS provides a more balanced view of a company's true financial health.
