How to Read an Earnings Report: 5 Numbers to Check Before You Trust the Headline

Intro
A company reports earnings. Revenue is above estimates. Profit is above estimates. The headline says "beat."
And the stock falls 8% the next morning.
If that has ever confused you, you are not alone. It happens because the headline answers one question, how did last quarter go, while the market is busy asking another: what happens next?
You do not need to read every page of a report to answer both. Five numbers do most of the work.
The short version: check revenue, earnings per share, margins, cash flow and guidance, in that order, and compare each against last year, not only against estimates.
1. Know Where to Find the Real Report
Press coverage is a summary of a summary. The source is easy to reach.
- The earnings release. Public companies publish results on their investor relations website. This is the fastest read.
- The 10-Q and the 10-K. These are the quarterly and annual filings submitted to the US Securities and Exchange Commission. They are longer and include the explanations behind the numbers.
- EDGAR. The SEC's database lets you search any US company's filings for free.
Start with the release, then use the filing when something needs explaining.
2. Revenue: Is the Business Growing?
Revenue is how much the company sold. It is the cleanest starting point because it is hard to dress up.
Compare it with the same quarter last year, not only with the previous quarter. Many businesses are seasonal, and a quarter-to-quarter drop can be normal.
Question to ask: is revenue growing faster, slower, or about the same as it was a year ago?
3. Earnings per Share: Beat or Miss?
Earnings per share (EPS) is profit divided by the number of shares. It is the number the headline usually leads with.
Analysts publish estimates before the report. Above the estimate is a beat. Below is a miss.
Two cautions. First, companies often report a "GAAP" figure and an "adjusted" figure, and they can differ a lot. Check which one the headline uses. Second, one quarter is one data point, not a trend.
Question to ask: is EPS higher or lower than last year, and than analysts expected?
4. Margins: How Much of Each Dollar Is Left?
Margins show how much of each dollar of sales becomes profit. Gross margin looks at the cost of making the product. Operating margin includes the cost of running the business.
A company can grow revenue and still look worse if its margins shrink. The reverse can also happen.
Question to ask: are margins rising, flat or shrinking, and does management explain why?
5. Cash Flow: Does the Cash Back Up the Profit?
Profit is an accounting number. Cash flow is the money that actually came in and went out.
If profit is rising while cash flow is falling, ask why. Sometimes the answer is harmless, such as timing. Sometimes it is a warning.
Question to ask: does cash flow support the profit that was reported?
6. Guidance: Why Stocks Move on What Comes Next
Guidance is what the company expects for the next period. It is often the most important part of the release.
This is why a stock can fall after a beat. The market prices the future. If the outlook is weaker than investors hoped, a good quarter can still disappoint. The reverse is also true.
For an example of how a stock can react in ways the headline does not predict, see our look at why Alphabet fell 10% after Q3 earnings.
Question to ask: is the outlook above or below what analysts expected, and did the company change it?
7. A 15-Minute Reading Order
When you only have a quarter of an hour:
- Read the summary at the top of the earnings release.
- Compare revenue and EPS with the same quarter last year.
- Check margins and cash flow.
- Read the guidance, and any change to it.
- Skim the management discussion for the reasons behind the numbers.
- Scan the risk factors for anything new.
Once you have the basics, the next step is judging the stock itself. Our guide on how to approach analyzing a stock picks up from here, and understanding the price-to-earnings ratio explains how earnings relate to price.
8. Using AI to Summarize Without Being Misled
AI tools can summarize long reports and earnings call transcripts in minutes. They are good at one thing in particular: finding what changed.
They can also misread a number or leave out a detail that matters. So use them for the first pass, then check any figure you plan to rely on against the report itself.

FAQ
How often do companies report earnings?
US public companies report quarterly, which is four times a year, and publish an annual report after the fiscal year ends.
What is a good EPS?
There is no single good number. Compare EPS with the same company's past results and with analyst estimates.
Does a beat mean I should buy?
No. A beat describes one quarter. It is not a reason to buy or sell.
Where can I read the full report for free?
On the company's investor relations page, and in the SEC's EDGAR database.
Final Thoughts
An earnings report is easier than it looks. Five numbers, one comparison with last year, and the guidance will get you most of the way.
Next time a headline says "beat," read those five numbers before you decide what it means.
