W.W. Grainger (GWW) Earnings: Q3 2026 Results and Next Report Date

The quarter ended September 30, 2026 and W.W. Grainger published the results on November 4, 2026. Revenue and diluted EPS are shown against Q3 2025, the same quarter a year earlier, which takes seasonal swings out of the comparison. W.W. Grainger reports EPS two ways: GAAP, under the accounting rules every US filer follows, and adjusted, which leaves out items the company considers outside its operating results. The release reconciles the two, and when they diverge, the reconciliation says why.

• Grainger exited the U.K. market in the fourth quarter of 2025 by selling Cromwell and closing Zoro U.K. Those other businesses had $87 million of sales in Q3 2025 and none in Q3 2026, which is why the segment rows do not add up to the year-ago total.
• MonotaRO, part of Endless Assortment, is majority owned and fully consolidated, and its results are reported one month in arrears.

How W.W. Grainger splits revenue in its own release, under its own labels, for Q3 2026 against Q3 2025. Indented lines are parts of the line above them.

• W.W. Grainger's High-Touch Solutions N.A. revenue was $4.1 billion in Q3 2026, up 14% from $3.6 billion in Q3 2025, 80% of total revenue.
• W.W. Grainger's Endless Assortment (Zoro and MonotaRO) revenue was $1.0 billion in Q3 2026, up 12% from $935 million in Q3 2025, 20% of total revenue.

Segment lines are the figures writers cite most often, because they show where the growth in a quarter came from. Companies redraw their segments from time to time and restate the prior year to match, so a year-ago figure here can differ from the one printed a year ago. When that has happened, the note above says so.

• Q3 2026 (this page), reported Nov 4, 2026

Grainger's net sales were $5,181 million in Q3 2026, up 11.3% from $4,657 million a year earlier.

High-Touch Solutions N.A., the Grainger-branded businesses in the U.S., Canada, Mexico and Puerto Rico, had sales of $4,135 million, up 13.8%, and was 80% of total company revenue. Grainger said the growth came from double-digit volume growth and continued price inflation as cost increases were passed. The segment's gross profit margin was 40.8%, down 30 basis points on unfavorable freight expense and mix. (Grainger Q3 2026 release, Nov 4, 2026; Grainger Form 10-Q, Q3 2026, Nov 4, 2026; Grainger Form 10-K, 2025, Feb 19, 2026)

Endless Assortment, the Zoro and MonotaRO online channels operating mainly in the U.S. and Japan, had sales of $1,046 million, up 11.9%, or 19.3% on a daily, organic constant currency basis. Grainger credited repeat business and enterprise customer growth at MonotaRO, while a weaker yen reduced growth by 6%. Segment operating earnings rose 48.8% to $122 million.

Manufacturing customers made up 30% of Grainger's Q3 2026 sales and government 16%, followed by wholesale (9%) and commercial services (8%). Grainger serves more than 4.6 million customers, and no single end customer accounted for more than 10% of total sales in 2025. (Grainger Form 10-Q, Q3 2026, Nov 4, 2026; Grainger Form 10-K, 2025, Feb 19, 2026)

Grainger's diluted EPS was $12.42 in Q3 2026, up 102.9% from $6.12, and adjusted diluted EPS was $12.54, up 22.8% from $10.21. The year-ago GAAP figure carried a $196 million loss from the U.K. exit, $4.09 a share. This quarter's only adjustment was $0.12 a share of transaction costs for the technology, intellectual property and talent assets Grainger bought from Adroit Worldwide Media, Inc. for $215 million on August 26, 2026. (Grainger Q3 2026 release, Nov 4, 2026; Grainger Form 10-Q, Q3 2026, Nov 4, 2026)

Grainger's effective tax rate fell to 24.3% from 34.7%; on an adjusted basis it was 24.3% against 24.8%, which Grainger attributed to additional tax credit benefits. Reported operating margin was 16.0% and adjusted operating margin 16.1%, against 15.2% adjusted a year earlier. (Grainger Q3 2026 release, Nov 4, 2026)

Diluted shares averaged 47.1 million, against 47.9 million. Grainger bought back 215,766 shares in the quarter, at average prices of $1,302.30 in August and $1,275.29 in September, and returned $396 million to shareholders through dividends and repurchases. Net earnings of $29 million went to MonotaRO's noncontrolling interest. (Grainger Form 10-Q, Q3 2026, Nov 4, 2026; Grainger Q3 2026 release, Nov 4, 2026)

Diluted EPS divides net income by the weighted average number of shares outstanding in the quarter, plus the shares that options and other equity awards could add. Buybacks shrink that count and lift EPS for the same profit; share issuance and stock awards enlarge it.

Grainger gives full-year guidance, on an adjusted basis, in its release. With Q3 2026 it raised 2026 diluted EPS guidance to $47.00 to $48.00 from $45.50 to $47.25, net sales to $19.8 to $20.0 billion from $19.4 to $19.7 billion, and daily, organic constant currency sales growth to 13.0% to 14.5%. (Grainger Q3 2026 release, Nov 4, 2026)

The updated 2026 ranges also call for operating margin of 16.0% to 16.2%, segment operating margin of 17.3% to 17.5% for High-Touch Solutions N.A. and 10.9% to 11.1% for Endless Assortment, and an effective tax rate of about 24.7%. (Grainger Q3 2026 release, Nov 4, 2026)

A consensus figure is the average of the models published by the analysts who cover W.W. Grainger, collected by a data provider and revised up to the day of the report. A quarter that lands above it says how expectations were set as much as how the business did, and the share price on the day also reflects the guidance and the lines no consensus covers.

The consensus figures on this page are Yahoo Finance's, as pulled on the date shown. Each comes with the number of analysts behind it; the smaller that number, the more one revised estimate can move the average.

The figures below are the ones W.W. Grainger's own release and filings put weight on for Q3 2026, with the latest reported value for each.

What the quarter means for a holding is a separate question from what it reported. The case for and against owning GWW is on is GWW a buy or a sell?, what analysts expect next is on the GWW forecast, and what the company does is on the W.W. Grainger (GWW) stock page.

Every number on this page can be traced to a document W.W. Grainger published. Checking one takes a couple of minutes, and it is worth doing before you quote a figure anywhere.

• The results release is the document linked in the source line above. Companies publish it on their investor relations site at the moment results go out, and it carries the headline tables: revenue, operating income, net income and EPS for the quarter and the year-ago quarter.
• The same release is filed with the SEC as Exhibit 99.1 to a Form 8-K under Item 2.02, usually on the day of the report. The SEC copy does not change after the fact, which makes it the safer thing to link when you cite a number.
• The quarterly report (Form 10-Q) follows within a few weeks and carries the full financial statements, the segment note and management's discussion of what changed. The fourth quarter is covered by the annual report (Form 10-K) instead.
• Restated comparisons are flagged in the notes on this page. When a company redraws its segments or changes how it adjusts EPS, it restates the year-ago column, so the year-ago figure in a new release can differ from the one printed a year ago. This page always uses the comparison in the newer release, because that is the like-for-like one.
