The quarter tells you what already happened. The line that often decides the market reaction is written in the future tense.
Published on September 16, 2026 · by Alex · Guide · Earnings · Fundamentals
To read a quarterly earnings report, start with revenue and its growth, then move through gross and operating margin, compare EPS with the prior period and expectations, and test profit against cash flow. Next, read guidance for the coming quarter, non-GAAP adjustments and the 10-Q risks: a record result may not be enough when the expected future was better.
A headline can say “record revenue” while the stock falls. The contradiction disappears when you separate three columns: what the company did, what it was expected to do, and what it now says it will do. The report contains all three, but not in the same place. The last one often moves the price most, and it usually comes after the numbers celebrated in the headline.
For a US company, “earnings” usually arrive as a package: the press release, a presentation, the analyst call and the Form 10-Q filed with the SEC. They do not carry the same weight.
| Document | What it is for | What may be missing |
|---|---|---|
| Release | Fast summary, comparisons and guidance | Full notes, risks and accounting policies |
| Presentation | Segments and visual operating metrics | Full context and less favourable items |
| Call | Management questions and nuance | Ordered regulatory text that is easy to compare |
| 10-Q | Financial statements, notes, MD&A, risks and controls | A simple explanation or investment thesis |
The quarterly 10-Q contains unaudited interim financial statements. The SEC advises reading them with the notes and MD&A, management's discussion of results, liquidity, trends and estimates. The release provides the map; the 10-Q verifies it. With the right source open, the reading starts at the top line.
Revenue is the sales recognised during the period. The first useful comparison is with the same quarter a year earlier; the second is with the previous quarter when the business is not highly seasonal. An isolated number does not show whether the company is accelerating, slowing or buying growth.
In its second quarter of fiscal 2027, ended July 26, 2026, NVIDIA reported $96.221 billion in revenue, up 18% from the previous quarter and 106% from a year earlier. That is a reported fact. The inference — that the business can sustain that pace — has not yet been proved and must be tested against demand, capacity, customer concentration and guidance.
Separate price, volume, acquisitions and currency when the company explains them. Two companies can both grow 20% while living opposite stories: one sells more units and the other merely charges more. To see how much of each sale is kept, move down one line.
Gross profit is revenue minus the direct cost of what was sold. Gross margin divides gross profit by revenue and shows how much of every dollar remains before research, sales, administration, interest and tax.
NVIDIA reported GAAP gross margin of 75.0% for the quarter, versus 72.4% a year earlier. The 2.6-percentage-point improvement is not the same as a 2.6% increase: margins are compared in points. The figure suggests better product economics or mix, but the cause belongs in the notes and MD&A; it should not be invented from the percentage.
A falling gross margin while revenue rises may signal discounting, higher costs, a less profitable mix or a product transition. No explanation is automatic. The next line shows whether the company converts gross profit into profit after running the business.
Operating income deducts costs such as research and development, sales and administration. Operating margin is operating income divided by revenue: it measures what the business keeps before interest and tax.
In this example, NVIDIA reported GAAP operating income of $63.734 billion. Divided by $96.221 billion in revenue, that is an operating margin of roughly 66.2%. The 66.2% is a calculation derived from reported figures, not a line published under that name. Operating expenses rose 55% year over year while operating income rose 124%: revenue scaled faster than operating spending during that period.
The trend matters more than an exceptional quarter. Keep the accounting basis consistent and check whether the margin depends on capitalised costs, share-based payments or adjustments that reappear. That leads to the per-share figure.
EPS divides attributable net income by the average share count. Start with diluted EPS, which includes instruments that could increase the number of shares. Compare three things: current EPS with the prior-year period, reported EPS with expectations, and EPS growth with net-income growth.
NVIDIA reported GAAP diluted EPS of $2.46, 128% above the prior year, and non-GAAP EPS of $2.22. The adjusted figure being lower is a useful reminder: “adjusted” does not automatically mean higher or more truthful. Open the reconciliation and read what was added or removed.
EPS also changes with buybacks, share issuance and stock-based compensation. If net income rises 10% but EPS rises 15%, part of the gap may come from fewer shares; if the reverse happens, dilution may be involved. EPS describes the result per share, not the quality of the cash behind it.
Profit uses accrual accounting: a sale may be recognised before it is collected. The cash-flow statement shows operating, investing and financing cash. Put net income beside operating cash flow and then estimate or read free cash flow, remembering that its definition can vary.
In the cited 10-Q, NVIDIA reported $63.059 billion in accounts receivable and $31.575 billion in inventory at July 26, 2026. Those figures are prompts for investigation, not proof of a problem by themselves. The balance sheet opens the questions; the notes show which ones have support.
EBITDA, adjusted EPS and adjusted free cash flow may help isolate items, but they do not replace GAAP figures. The SEC requires a comparable GAAP measure and quantitative reconciliation when applicable, and warns that non-GAAP measures can mislead or fail to be comparable when they are poorly labelled or adjusted.
A practical test uses three columns: adjustment, amount and recurrence. A one-time severance charge may deserve separate analysis. Stock compensation excluded every quarter for years is a recurring cost to shareholders even when no cash leaves that day. If the company changes a definition, recalculate previous periods before comparing.
Once the past is reconciled, the section the market is trying to anticipate comes next.
Guidance is management's estimate for a future period: revenue, margin, expenses or other metrics. It is neither a promise nor a realised GAAP figure. Compare it with prior guidance, consensus and what appears to be embedded in the share price.
On August 26, 2026, NVIDIA guided fiscal third-quarter revenue to $108.0 billion, plus or minus 2%, GAAP and non-GAAP gross margin to 74.0%, plus or minus 0.5 percentage points, and GAAP operating expenses to about $9.2 billion. It also said the outlook assumed no Data Center compute revenue from China. That assumption matters as much as the midpoint because it defines what scenario the guidance includes.
Guidance above the prior quarter may still disappoint if the market expected more. Guidance below the prior figure may be welcomed if the price already reflected something worse. Without a reliable source for the prior consensus, do not label the difference a “surprise.”
Imagine the market expected record revenue of 100, EPS of 2.50 and guidance of 120. The company reports 105 and 2.60 — both records — but guides to 108 and says margin will fall. The past beat the record; the future fell short of the expectation. An 8% drop would be consistent with that revision, although the percentage alone could never prove the cause.
Customer concentration, regulatory change, an accounting item, inventory, dilution or the tone of the call may also matter. The price reaction is evidence that the combined expectation changed, not a single explanation. The mistake is to invent the cause after seeing the chart.
This closes the loop from the opening: the decisive line was not hidden inside record revenue. It was in the comparison between guidance, assumptions and expectations.
An earnings report does not give a buy or sell order. It gives evidence with which to update a thesis. Reported figures are facts; calculated margins are derivations; claims about sustainability are inferences; guidance is an estimate subject to risks.
Nothing in this guide is financial, accounting, legal or tax advice. If a report is used to estimate after-tax returns, treatment depends on the investor's tax residence, the fund or vehicle domicile and the rules currently in force. Check the applicable rules before making a decision.
Main sources consulted: SEC/Investor.gov, how to read a 10-K or 10-Q; NVIDIA Form 10-Q for the quarter ended July 26, 2026; NVIDIA fiscal Q2 2027 results (Aug. 26, 2026); SEC interpretations on non-GAAP measures. NVIDIA figures and guidance reflect those publications and may become outdated; check the latest filing.
Identify the reporting period and units first; then read revenue, gross margin, operating margin and EPS in that order. Compare each line with the same quarter a year earlier and, when seasonality matters, with the immediately preceding quarter. Only then compare the result with expectations and forward guidance.
The release summarises the numbers and the message the company wants to highlight. The 10-Q is the regulatory filing with the SEC: it contains unaudited interim financial statements, notes, management discussion, risks and controls. Use the release to orient yourself and the 10-Q to verify.
Because price reacts to the difference between what happened and what the market already expected. A record can arrive with slower growth, lower margin, guidance below expectations or a new risk. The fall alone does not prove the business deteriorated; it shows that the new information was worse than what the price had reflected.
Use both. GAAP EPS follows standardised accounting rules; adjusted EPS removes items selected by the company and may help isolate operations, but it is not automatically comparable across companies. The reconciliation and the recurrence of supposedly exceptional adjustments often contain the most useful information.
No. Guidance is management’s estimate based on information available at the time and is subject to assumptions and risks. Use it to compare what the company expects now with what it expected before and what the market had priced in, not as a guarantee of the next result.
