How to Read an Earnings Report in 20 Minutes

The headline EPS is the least useful number in the release. It describes a quarter that closed weeks ago, against a consensus figure twenty analysts have been converging on for months. It moves the price in the first second because machines read it first. Then the humans arrive, find the guidance line and the margin trend, and the move reverses about as often as it extends. Read the quarter in this order and you will be one of the humans.

What arrives, and when

Companies report after the close or before the open. Almost never during the session. The press release hits the wire at a scheduled minute, the call starts thirty to sixty minutes later, and the 10-Q with the full statements lands anywhere from the same day to several weeks afterward.

Document	Contains	Reading time
Press release	Headline revenue and EPS, segment tables, guidance, management quote	5 minutes
Slide deck	Charts of the same data, unit metrics, sometimes a margin bridge	5 minutes
Conference call	Prepared remarks, then analyst questions	60 minutes
10-Q or 10-K	Full statements, footnotes, risk factors, share count detail	30 minutes and up

The first two documents are written by the company to be read the way the company wants them read, and the filing is written to satisfy the SEC. When they disagree, believe the filing.

Revenue and EPS

Revenue is what the company sold. Earnings per share is net income divided by the weighted average share count. That second number is the one the wire compares against consensus.

Work it through. A company reports net income of $520 million on 130 million average shares. EPS is $520m / 130m = $4.00. Consensus stood at $3.92. The beat is 8 cents, or 0.08 / 3.92 = 2.0%.

Now look at what produced it. The share count is in the denominator, so it moves EPS with no help from the business: spread that same $520 million over 125 million shares after a repurchase program and EPS is $520m / 125m = $4.16. Four percent higher. The company sold nothing extra. That mechanism gets its own treatment in stock buybacks explained.

Then growth. Compare revenue against the same quarter a year earlier, never against the previous quarter, because most businesses have a seasonal shape and a retailer’s December quarter always beats its September quarter. That comparison tells you nothing.

GAAP, and the company’s own version of GAAP

GAAP is the rulebook every US public company reports under. Adjusted earnings, also called non-GAAP, are the company’s own presentation with items it considers unrepresentative removed.

Some of those adjustments are fair. A genuine one-time legal settlement tells you nothing about next year. Others are editorial. Stock-based compensation is the big one. It is a real cost, paid in shares, and it dilutes you, and excluding it flatters earnings every single quarter without exception.

Measure	Hypothetical quarter	What it includes
GAAP net income	$520m	Everything, including stock compensation and restructuring
Adjusted net income	$655m	Excludes $95m stock compensation and $40m restructuring
GAAP EPS	$4.00	130m shares
Adjusted EPS	$5.04	130m shares

That is a 26% gap, and the gap is the company’s opinion of its own results. Track it across several years. When restructuring charges show up in eight consecutive quarters, they are an operating cost wearing a different label, and the company reporting them knows that. Earnings quality and accounting red flags goes through the patterns that surface in accruals and receivables well before they surface in the price.

Cash flow is the check on the story

Net income depends on judgment calls: when revenue is recognized, how costs are spread, what gets capitalized. Cash flow from operations is closer to what actually moved through the bank account.

Put the two side by side over four quarters. Net income that keeps running ahead of operating cash flow means profit is being booked before the cash shows up, and that usually appears as growing receivables or swelling inventory. Free cash flow, which is operating cash flow minus capital spending, is what remains to pay dividends, repurchase stock or reduce debt.

Guidance is the line that moves the price

Everything above describes a finished period the market has already estimated. Guidance is the company telling you what comes next. That is where the move comes from.

Read it as a range and read what changed in the range. Full-year revenue guidance moving from $6.7bn to $6.9bn is a raise. The same range held steady after a strong first half implies a weaker second half than the market was carrying, and the stock will trade on the implication. Check the assumptions attached: currency, tax rate, share count. A guidance raise built on a lower tax rate is worth less than one built on volume, and the sell side will make that distinction on the call within ten minutes.

Some companies give annual ranges only, and some give nothing. Where there is no guidance, the call is the whole story.

The call

Prepared remarks are scripted and add almost nothing to the slide deck. Skip to the questions.

Listen for the question asked more than once by different analysts. That marks the issue the market cares about. Listen for the answer that changes shape between the first asking and the third, and note when management declines to quantify something they quantified last quarter, because a metric that stops being disclosed stopped being flattering first.

Why a beat sells off

Here is the folklore: the company beat, so the stock should go up. Here is what happens.

Published consensus is an average of analyst models. The number that sets the price is what the large holders actually expect, which for a company that has beaten six quarters running sits well above consensus. A 2% beat against a book positioned for 5% is a miss in everything except the headline. Nobody publishes the second number. You infer it from how the stock traded into the print.

Then there is the material the algorithms had not reached yet: margin compression, a guidance range implying a soft second half, a segment that stopped growing, a tax rate doing the work, and the first move often reverses inside the hour as people get to page four. The price twenty minutes after a release is a more considered number than the price twenty seconds after it, and paying for immediacy in that window is expensive.

Options add their own mechanism. Implied volatility is bid up into a report and collapses once the uncertainty resolves, which is covered in implied volatility explained, and how prices behave in the days afterward, including the tendency of surprises to keep drifting the same way, is in trading earnings season.

Once you can read a quarter, the output feeds straight into price. Stock valuation basics turns that $4.00 into a multiple, the P/E ratio calculator does the arithmetic, and the stock screener finds the companies whose growth and multiple have come apart.
