Core idea

Overview

Earnings Per Share (EPS) is a fundamental financial metric that represents the portion of a company's net income assigned to each outstanding share of common stock. It provides a standardized way for investors to evaluate profitability across companies of different sizes or share structures.

When to use: Analysts use EPS during financial statement reviews to track a company's earnings trajectory over multiple fiscal periods. It is also an essential component in valuation models, such as the Price-to-Earnings ratio, used to determine if a stock is fairly priced.

Why it matters: EPS directly influences stock prices as it signals the potential for dividend payouts and future business expansion. A consistently growing EPS reflects strong operational performance and management's ability to generate value for shareholders.

Derivation

Formula: Earnings Per Share (EPS)

EPS allocates a company's net profit to each individual share, indicating how much profit 'belongs' to a single share of stock.

  • Net profit used is after tax and preference dividends.
  • Share count is the weighted average number of ordinary shares in issue.

Divide net profit by total shares outstanding:

EPS is one of the most watched metrics in equity analysis. Rising EPS signals growing profitability per share. It is also the denominator of the Price-to-Earnings ratio.

Graph

The graph of Earnings Per Share (eps) against the independent variable Net Profit is a straight line starting at the origin. This linear shape occurs because Earnings Per Share is directly proportional to Net Profit, assuming the Total Shares remain constant.

Why it behaves this way

Intuition

Imagine a company's total net profit as a single pie, and the total shares outstanding as the number of equal slices this pie is divided into, with each slice representing the earnings attributable to one share.

EPS
The portion of a company's net income assigned to each outstanding share of common stock.
It shows how much profit the company made for each share, directly indicating a shareholder's claim on earnings.
Net Profit
The total profit remaining after all operating expenses, interest, and taxes have been deducted from revenue.
This is the total amount of earnings available to shareholders and for potential reinvestment.
Total Shares
The total number of common stock shares currently held by investors.
This represents the total number of units into which the net profit is divided.

Avoid these traps

Common Mistakes

  • Using revenue instead of net profit.
  • Convert units and scales before substituting, especially when the inputs mix £, shares, £/share.
