What is an Earnings Report?

An earnings report is a quarterly update that publicly listed companies are required to publish showing their financial results for the past three months. It is one of the most closely watched events in the investing calendar, often causing significant moves in a company's share price on the day it is released.

What does an earnings report contain?

The headline figures are revenue and earnings per share, which shows how much profit was generated for each outstanding share. Companies also typically provide guidance, meaning their own forecasts for the coming quarter or year. Beyond the numbers, most companies hold an earnings call where management discusses the results and takes questions from analysts.

Why do share prices move so much on earnings day?

Because the market is constantly forming expectations. Analysts and investors build models predicting what a company will earn. If the actual results beat those expectations, the stock often rises. If they miss, it often falls sometimes sharply, even if the company is still profitable. The reaction is about surprise, not just performance in absolute terms.

Do you need to follow every earnings report?

If you invest in broad index funds, no. Earnings reports matter most to investors who hold individual stocks. If you own shares in a specific company, reading its quarterly earnings is part of staying informed about what you own.
