Reading an Earnings Report: The Lines That Matter

An earnings report is not one document but a sequence: a press release furnished to the SEC on Form 8-K, usually a conference call, and a quarterly report on Form 10-Q (or an annual 10-K) with fuller statements and notes. The lines that carry the most information are revenue and its growth, gross and operating margin, diluted earnings per share, operating cash flow minus capital spending, and the reconciliation that links any adjusted figure back to the GAAP number. Reading those in order, knowing which document each comes from, answers most of what a quarter can tell.

Key takeaways

The press release carries no assurance of its own; the 10-Q's statements are reviewed, not audited; only the 10-K's annual statements are audited.
Diluted EPS divides net income by a share count that includes potential shares from equity awards, so buybacks and new awards move EPS even when profit does not change.
In SEC filings and in earnings releases furnished on Form 8-K, a non-GAAP figure needs the comparable GAAP figure shown with equal or greater prominence and a quantitative reconciliation.
Adjusted earnings are not always higher than GAAP earnings: in the worked example, excluding investment gains made non-GAAP diluted EPS $2.22 against GAAP diluted EPS of $2.46.

Where each number is published

When a company publicly announces results for a completed quarter or year, Item 2.02 of Form 8-K requires it to give the date of the release and attach its text as an exhibit, normally Exhibit 99.1, within four business days of the announcement. That report is "furnished" rather than "filed," a distinction covered in the questions below.

A call needs no 8-K of its own if it begins within 48 hours after a furnished written release, is broadly accessible by phone or webcast, was announced in advance by a widely disseminated press release, and its financial information, with non-GAAP reconciliations, is posted on the company's website (Item 2.02(b)). Item 2.02 does not apply to results disclosed in the 10-Q or 10-K itself.

Document	What it contains	Timing	Level of assurance
8-K, Item 2.02, with Exhibit 99.1	Headline results, summary statements, non-GAAP reconciliations, often guidance	Within four business days of the announcement; sometimes days or weeks before the 10-Q	None required for the release itself; tables are usually marked "unaudited"
Earnings call and slides	Management commentary, analyst questions, sometimes extra metrics	Usually the same day as the release	None
Form 10-Q (quarters 1 to 3)	Condensed statements, notes, segment data, MD&A, risk-factor updates, buyback table	40 days after quarter end (large accelerated and accelerated filers); 45 days (all others)	Reviewed by an independent accountant before filing
Form 10-K (full year)	Full statements and notes, auditor's report, MD&A, business and risk sections	60 days after year end (large accelerated); 75 days (accelerated); 90 days (all others)	Audited

Deadlines are from the general instructions to Form 10-Q and Form 10-K, as of October 2026; filer status is on the 10-Q cover page. Rule 10-01(d) of Regulation S-X requires an independent accountant to review the quarterly statements before the 10-Q is filed. A review under PCAOB standard AS 4105 consists mainly of analytical procedures and inquiries, is much narrower than an audit, and ends without an audit opinion. The 10-K's annual statements are audited and, for most filers, cover three years of income and cash flows under Rule 3-02 of Regulation S-X.

Income statement lines to read

The SEC's beginners' guide to financial statements compares the income statement to a set of stairs: revenue at the top, costs subtracted step by step, net income at the bottom.

Revenue, gross margin and operating income

Revenue is sales for the period; its growth and source matter more than its size.
Gross margin is gross profit (revenue minus cost of revenue) divided by revenue: the share of each sales dollar left after the direct cost of what was sold.
Operating income subtracts operating expenses such as research and development and selling, general and administrative costs; operating margin divides it by revenue.

Other income, net income and diluted EPS

Between operating income and net income sit interest, investment gains and losses, and income tax; a large investment gain can lift net income with no change in operations.

Earnings per share comes in two versions under US GAAP (ASC Topic 260). Basic EPS divides net income by the weighted average number of shares outstanding during the period. Diluted EPS adds the shares that would exist if dilutive stock options, restricted stock units and similar instruments were converted, commonly computed with the treasury stock method. Because the denominator is an average, a buyback partway through a quarter only counts for part of it.

Gross margin      = (Revenue - Cost of revenue) / Revenue
Operating margin  = Operating income / Revenue
Basic EPS         = Net income / Weighted average basic shares
Diluted EPS       = Net income / (Weighted average basic shares
                                  + Dilutive potential shares)
Growth rate       = (Current period / Comparison period) - 1

The formulas are simplified for a company with only common stock; both share counts are in the EPS note of the 10-Q or 10-K.

Cash flow, segments and guidance

Operating cash flow and capital spending

The cash flow statement starts from net income and adjusts for non-cash items and changes in working capital, such as receivables and inventory, to reach operating cash flow. Subtracting capital expenditures (purchases of property and equipment, under investing activities) gives the common version of free cash flow.

Free cash flow is a non-GAAP measure with no uniform definition, so the company's own formula matters; the SEC staff's non-GAAP interpretations (Question 102.07) ask for a clear description and reconciliation. And Rule 10-01(c) requires the 10-Q cash flow statement only for the year-to-date period, so a second- or third-quarter figure is found by subtracting the previous 10-Q, unless the press release shows the quarter separately.

Segment note

The segment note shows revenue and profit by the business units management uses to run the company. Under FASB Accounting Standards Update 2023-07, public companies must also disclose significant segment expenses regularly provided to the chief operating decision maker, in quarterly as well as annual reports, and that person's title in annual reports. According to KPMG's summary of the update, it applies to fiscal years beginning after December 15, 2023, and to interim periods within fiscal years beginning after December 15, 2024. Press releases often group revenue by market or product line instead, so the two do not always match.

Guidance and the safe harbor

Guidance, management's forecast for a coming period, is a forward-looking statement. Under the private-litigation safe harbor in the Private Securities Litigation Reform Act, codified at 15 U.S.C. 78u-5, a reporting company is generally not liable in private lawsuits for such a statement if it is identified as forward-looking and accompanied by meaningful cautionary statements naming important risk factors, if it is immaterial, or if the plaintiff cannot prove it was made with actual knowledge that it was false. It does not cover statements inside GAAP financial statements, in an initial public offering or tender offer, and other listed categories. Hence the long cautionary lists at the end of releases.

GAAP vs non-GAAP figures

Three layers of rules govern "adjusted" figures.

Regulation G applies whenever an SEC-reporting company publicly discloses a non-GAAP measure, in any medium: it must present the most directly comparable GAAP measure and a quantitative reconciliation of the difference, and the presentation must not be misleading.
Item 10(e) of Regulation S-K adds, for filed documents, that the GAAP measure must have equal or greater prominence and that the company must say why management thinks the measure is useful. Instruction 2 to Item 2.02 applies these paragraph (e)(1)(i) requirements to the furnished earnings release as well.
The SEC staff's interpretations give examples of undue prominence (Question 102.10): a non-GAAP number placed before the GAAP one, including in a headline, non-GAAP figures in bolder or larger type, a reconciliation that starts from the non-GAAP figure, or a full non-GAAP income statement.

How "one-time" items are labeled

Item 10(e) bars a filed document from adjusting a performance measure for an item described as non-recurring, infrequent or unusual if a similar charge or gain is reasonably likely within two years or occurred within the prior two years. The staff reads that as a limit on the label, not on the adjustment itself (Question 102.03). Separately, excluding normal, recurring cash operating expenses can make a measure misleading (Question 100.01). The reconciliation shows which adjustments a company used, and changes to the list between periods should be disclosed and explained (Question 100.02).

Restatements and revisions

A 2022 statement by the SEC's chief accountant describes two ways to correct an error in past statements: an error material to them requires reissuing them (a "Big R" restatement), while an error not material to them but material to the current period can be fixed in the comparative figures of the current report (a "little r" revision). Both count as restatements under GAAP. When the board or authorized officers conclude past statements should no longer be relied on, Item 4.02 of Form 8-K requires a filing naming the periods affected; a notice from the auditor triggers one too. A change in segment structure or in a non-GAAP definition recasts prior figures without any error.

A worked example: one real quarter

The figures below come from NVIDIA Corporation's Form 8-K dated August 26, 2026, its Exhibit 99.1 press release, and its Form 10-Q for the quarter ended July 26, 2026 (second quarter of fiscal 2027). The company was chosen only because its filing illustrates several mechanisms; nothing here is a view on the shares.

Line ($ millions except per share)	Q2 FY2027	Q2 FY2026	Calculation
Revenue	96,221	46,743	96,221 / 46,743 - 1 = 105.9% year over year
Gross margin	75.0%	72.4%	72,142 / 96,221 vs 33,853 / 46,743
Operating margin	66.2%	60.8%	63,734 / 96,221 vs 28,440 / 46,743
Net income	59,688	26,422	Up 125.9%
Diluted EPS (GAAP)	$2.46	$1.08	Up $1.38, or 127.8%
Diluted weighted shares (millions)	24,285	24,532	Down 247 million, or 1.0%
Free cash flow, simple (CFO - capex)	21,400	13,471	24,077 - 2,677 vs 15,365 - 1,894

Read together, the lines show four things.

Share count helps EPS a little. Diluted EPS grew slightly faster than net income (127.8% against 125.9%) because the diluted share count was 1.0% lower than a year earlier. In this quarter alone, the 10-Q shows 94 million shares repurchased for $19.7 billion, partly offset by shares issued under employee plans.
Sequential comparison tells a different story below the operating line. Against the previous quarter, revenue rose 17.9% and operating income 19.0%, but net income rose only 2.3%. Other income fell from $16,367 million to $7,773 million, mostly because gains on equity securities dropped from $15,936 million to $7,771 million.
Cash flow was well below net income. Operating cash flow of $24,077 million was about 40% of net income; the two largest reasons were a $22,346 million rise in receivables and the $7,771 million of non-cash investment gains. The company's own free cash flow, which also subtracts $59 million of principal payments on property and intangible assets, was $21,341 million. From the 10-Q alone, the quarter is six-month operating cash flow of $74,421 million minus the first quarter's $50,344 million.
Segments and the release use different groupings. The release reports Data Center revenue of $89.0 billion; the 10-Q's segments are Compute & Networking ($88,299 million) and Graphics ($7,922 million). Segment operating income totals $66,595 million, $2,861 million more than consolidated operating income, because stock-based compensation ($2,027 million), acquisition-related costs ($222 million) and other unallocated expenses ($612 million) are not charged to segments.

The GAAP to non-GAAP bridge

The release's reconciliation starts from the GAAP figure, as the SEC staff expects:

Step	$ millions
GAAP net income	59,688
Add back acquisition-related and other costs in operating income	+222
Remove gains from equity securities, net	-7,771
Other items in other income (derivatives, equity-method results and similar)	+298
Income tax effect of the adjustments	+1,517
Non-GAAP net income	53,954
Divided by 24,285 million diluted shares	$2.22 per share

Non-GAAP diluted EPS was $0.24 below GAAP because the largest adjustment removed a gain, not a cost. The release also states that, starting in the first quarter of fiscal 2027, its non-GAAP measures no longer exclude stock-based compensation, and that earlier periods were updated to match. Comparisons with older non-GAAP figures need the recast numbers.

Comparing quarters and consensus

Year over year or sequential

The 10-Q income statement must show the current quarter next to the same quarter of the prior year (Rule 10-01(c)(2)), and that comparison removes most seasonal effects. Illustrative example: a retailer with $10 billion of revenue in its holiday quarter and $7 billion the next shows a 30% sequential fall that may mean nothing; if the year-earlier figures were $9.5 billion and $6.6 billion, the two quarters grew about 5% and 6% year over year. Sequential comparisons spot a turn sooner, if the business is not strongly seasonal and the quarters are equally long.

Beat or miss

"Beat" and "miss" compare reported results with a consensus estimate: an average of analysts' forecasts compiled by private data providers. Consensus is not part of any SEC filing, and providers differ in which analysts they include and whether the EPS estimate is GAAP or adjusted. A company can beat on one basis and miss on the other, so check the basis and compare with the company's own earlier guidance.

Frequently asked questions

Does "furnished, not filed" make the press release less reliable?

It changes legal liability, not content. Under General Instruction B.2 of Form 8-K, a furnished Item 2.02 report is not subject to Section 18 of the Exchange Act unless the company states otherwise or incorporates it into another filing. Regulation G's ban on misleading non-GAAP presentations still applies, and the same figures normally reappear in the reviewed 10-Q or audited 10-K.

Why is there no 10-Q for the fourth quarter?

Form 10-Q's general instructions require quarterly reports only for the first three fiscal quarters; the 10-K covers the full year instead. Fourth-quarter figures usually appear only in the press release, or can be derived by subtracting nine-month 10-Q totals from 10-K annual amounts.

Does a company have to update its guidance if things change?

The safe harbor statute states that it imposes no duty to update a forward-looking statement (15 U.S.C. 78u-5(d)), though companies may choose to. Separately, releasing new or updated material information about a completed quarter triggers another Item 2.02 report (Instruction 1 to Item 2.02).

Can the numbers be downloaded instead of copied from the PDF?

Yes. The SEC's EDGAR data APIs publish XBRL-tagged financial data from 10-Q, 10-K and 8-K filings as JSON, with no API key required; the companyfacts endpoint returns every tagged figure for one company, with period dates that separate year-to-date from quarterly values.

Can a company report free cash flow per share?

Not in SEC documents. The staff's non-GAAP interpretations (Question 102.07) treat free cash flow as a liquidity measure that must not be presented on a per-share basis, and warn against implying it is cash free for discretionary spending when debt service and other commitments have not been deducted.

Questions to ask of any report

Is this figure from the release, the reviewed 10-Q or the audited 10-K?
How fast did revenue grow year over year, and which segment or product line produced the growth?
Did gross and operating margin widen or narrow, and does the release or MD&A say why?
How much of the change in net income came from below the operating line?
Did diluted shares rise or fall, and how much did that change EPS compared with net income?
Is operating cash flow close to net income, for this quarter alone rather than year to date?
What does the GAAP to non-GAAP reconciliation add back or remove, and did the list change from last year?
Is any adjustment labeled "one-time" that has appeared in the past two years?
Was guidance given, what range does it imply, and on a GAAP or non-GAAP basis?
Has the company filed an Item 4.02 8-K or recast prior periods since the last report?
