Earnings per share

As explained in Investing for Programmers

Earnings per share is a company’s net income attributable to common shareholders divided by its outstanding common shares.

Earnings per share (EPS) measures a company’s profit attributable to each outstanding common share: (profit − preferred dividends) ÷ shares outstanding. It is calculated from income-statement earnings and supports valuation analysis. section 2.4.3 section 2.4

EPS is useful, but not decisive. Compare it with other metrics, industry peers, and the company’s broader financial condition. Earnings-call results above or below expectations can affect the stock price. section 2.4 section 2.4.3

Reading EPS trends

Annual EPS data for four LiDAR producers shows mostly negative earnings from 2020 through 2024, with some lower values during the COVID years. Early-stage companies may remain unprofitable while investors focus on projected earnings, but that outlook carries risk. section 4.2.1 section 4.2.1

(Profit – Preferred dividends) ÷ Shares outstanding

Use the equation to calculate EPS consistently before comparing companies or applying valuation ratios such as P/E. section 2.4.3
