What is earnings per share (EPS) in stock investing, and what is its significance?

Earnings per share (EPS), also known as net profit per share or earnings per common share, refers to the ratio of a company’s after-tax net income to its total number of outstanding shares. It represents the portion of a company’s net profit (or net loss) attributable to each outstanding common share held by ordinary shareholders. EPS is commonly used to reflect a company’s operating performance, gauge the profitability and investment risk associated with its common stock, and serves as a key financial metric for investors and other stakeholders to evaluate corporate profitability, forecast growth potential, and make related economic decisions. Among the many tools employed in fundamental stock analysis—such as the price-to-earnings (P/E) ratio, price-to-book (P/B) ratio, and discounted cash flow (DCF) analysis—EPS is one of the most frequently referenced indicators. EPS TTM (Trailing Twelve Months) refers to the EPS calculated using the net income from the most recent twelve consecutive months, divided by the latest total number of outstanding shares. TTM data is a rolling figure that changes every quarter. Although its starting point shifts over time, it always encompasses four distinct quarters (e.g., Q1–Q4; Q2–Q1; Q3–Q2; Q4–Q3). Although these four quarters may span two different calendar years, this approach effectively mitigates the impact of seasonal fluctuations inherent in corporate operations.

The P/E ratio equals share price divided by EPS—but why does the calculated value often differ from the actual reported figure?

Your general understanding is correct, but there is a subtle error in the details. EPS stands for earnings per share. Q1 EPS means the earnings per share for the first quarter only. Q2 EPS means the cumulative earnings per share for Q1 plus Q2. Q3 EPS means the cumulative earnings per share for Q1 through Q3. Q4 EPS means the cumulative earnings per share for Q1 through Q4 (i.e., full-year EPS). For example, the EPS shown for December 31, 2018, in the chart is 0.7362. Dividing the current share price by 0.7362 yields the stock’s static P/E ratio. To calculate the sum of EPS for the most recent four quarters (i.e., the trailing twelve-month EPS): Suppose it is now Q1 of the current year. Then: 2018 full-year EPS (0.7362) − 2018 Q1 EPS (0.3373) + 2019 Q1 EPS (0.1549) Dividing the current share price by this result yields the trailing twelve-month P/E ratio (TTM P/E). Additional note: Preferred shares are also equity securities and participate in profit distribution.
