CHICAGO, Feb. 3, 2026 - Grainger (NYSE: GWW) today reported results for the fourth quarter and full year 2025. Sales of $4.4 billion in the fourth quarter of 2025 increased 4.5%, or 4.6% on a daily, organic constant currency basis versus the fourth quarter of 2024. For the full year, sales of $17.9 billion increased 4.5%, or 4.9% on a daily, organic constant currency basis compared to the prior year.

“In 2025, we executed well, delivering exceptional service and a best-in-class experience for our customers across both our High-Touch Solutions and Endless Assortment segments,” said D.G. Macpherson, Chairman and CEO. “Despite a challenging macro environment, we drove profitable share gain, made strong progress with our strategic initiatives, and operated with resiliency. I’m very proud of the Grainger team and believe we are poised to drive strong performance moving forward."

(1)Reflects the loss from the Company's exit of the U.K. market, including the sale of the Cromwell business and closure of Zoro U.K. announced in the third quarter of 2025 and completed in the fourth quarter of 2025.

(2)Reflects restructuring costs incurred in the second quarter of 2024.

(3)See the supplemental information of this release for further information regarding the Company's non-GAAP financial measures including reconciliations to the most directly comparable GAAP measure.

For the fourth quarter of 2025, total Company sales were up 4.5%, or up 4.6% on a daily, organic constant currency basis compared to the fourth quarter of 2024.

In the High-Touch Solutions - N.A. segment, sales were up 2.2%, or 2.1% on a daily, constant currency basis versus the fourth quarter of 2024 driven by continued growth in the U.S. and Canada, including increases across most customer end markets. In the Endless Assortment segment, sales were up 14.3%, or 15.7% on a daily, organic constant currency basis versus the prior year quarter. Growth for the segment was driven by strong performance at both MonotaRO and Zoro.

For the full year 2025, total Company sales increased 4.5% versus the full year of 2024. Daily sales on an organic, constant currency basis increased 4.9% versus the prior year driven by growth in both segments.

For the fourth quarter of 2025, total Company gross profit margin was 39.5%, a decrease of 10 basis points compared to the fourth quarter of 2024 due primarily to segment mix headwinds.

In the High-Touch Solutions - N.A. segment, gross margin was flat compared to the prior year quarter as various factors offset. In the Endless Assortment segment, gross margin increased by 70 basis points versus the fourth quarter of 2024 due to improvement across the segment.

For the full year 2025, total Company gross profit margin was 39.1%, down 30 basis points versus the prior year. The decrease in gross profit margin was primarily driven by tariff-related inflation which caused unfavorable price / cost timing and last-in, first-out (LIFO) inventory valuation headwinds in the High-Touch Solutions - N.A. segment.

For the fourth quarter of 2025, operating earnings for the total Company were $634 million, up 0.2% over the fourth quarter of 2024, as sales growth was largely offset by lower margin. Operating margin was 14.3%, a 70 basis point decrease compared to the prior year quarter. This decrease in operating margin was primarily due to increased expense, including unforeseen healthcare costs, and slower sales growth in the High-Touch Solutions - N.A. segment.

Diluted EPS for the fourth quarter of 2025 was $9.44, down 2.8% versus the prior year quarter. The decrease was primarily due to an unfavorable tax rate compared to the prior year quarter which was only partially offset by fewer shares outstanding.

For the full year 2025, reported operating earnings for the total Company of $2.5 billion were down 5.4% versus the prior year, as sales growth was offset by lower margin including the loss recorded in the third quarter of 2025 related to the Company’s exit from the U.K. market. Reported operating margin was 13.9%, a decrease of 150 basis points over prior year. Diluted EPS for the full year 2025 was $35.40 on a reported basis, down 8.6% versus 2024, as fewer shares outstanding were more than offset by an unfavorable tax rate compared to the prior year.

On an adjusted basis, which excludes the loss related to the Company’s exit from the U.K. market in the third quarter of 2025 and restructuring costs incurred in the second quarter of 2024, full year 2025 operating earnings were up 1.4%, or $2.7 billion, as sales growth was largely offset by lower margin. Adjusted operating margin of 15.0% decreased 50 basis points compared to 2024 due primarily to lower gross margin, higher operating expenses, and slower sales growth in the High-Touch Solutions - N.A. segment. Adjusted diluted EPS was $39.48, up 1.3% versus the prior year, as fewer shares outstanding were offset by an unfavorable tax rate compared to the prior year.

For the fourth quarter of 2025, the effective tax rate was 22.8% compared to 20.1% in the fourth quarter of 2024. The variance was driven primarily by the release of a tax reserve following the expiration of a statute of limitation period that occurred in the prior year quarter.

For the full year 2025, the reported effective tax rate was 25.6% versus 23.0% in 2024, with the increase primarily due to the loss from the Company's exit of the U.K. market, for which there was no corresponding tax benefit. On an adjusted basis, the full year effective tax rate was 23.7% versus 23.0% in 2024, with the increase driven primarily by the release of a tax reserve following the expiration of a statute of limitation period that occurred in the prior year.

During the fourth quarter of 2025, the Company generated $395 million of cash flow from operating activities as net earnings were partially offset by unfavorable working capital. The Company invested $126 million in capital expenditures, resulting in free cash flow of $269 million. During the quarter, the Company returned $355 million to Grainger shareholders through dividends and share repurchases.

For the full year 2025, the Company generated $2.0 billion of cash flow from operating activities. The Company invested $684 million in capital expenditures, resulting in free cash flow of $1.3 billion in 2025. During the year, the Company returned $1.5 billion to Grainger shareholders through dividends and share repurchases.

The Company is providing the following outlook for 2026:

(1)Guidance provided is on an adjusted basis.

The Company supplements the reporting of financial information determined under U.S. generally accepted accounting principles (GAAP) with the non-GAAP financial measures as defined below. The Company believes these non-GAAP financial measures provide meaningful information to assist investors in understanding financial results and assessing prospects for future performance as they provide a better baseline for analyzing the ongoing performance of its business by excluding items that may not be indicative of core operating results.

Basis of presentation

The Company has a controlling ownership interest in MonotaRO, which is part of our Endless Assortment segment. MonotaRO’s results are fully consolidated, reflected in U.S. GAAP, and reported one-month in arrears. Results will differ from MonotaRO’s externally reported financials which follow Japanese GAAP.

Adjusted gross profit, adjusted SG&A, adjusted operating earnings, adjusted operating margin, adjusted net earnings, adjusted diluted EPS

Exclude certain non-recurring items, like restructuring charges, asset impairments, gains and losses associated with business divestitures and other non-recurring, infrequent or unusual gains and losses (together referred to as “non-GAAP adjustments”), from the Company’s most directly comparable reported U.S. GAAP figures (reported gross profit, SG&A, operating earnings, net earnings and EPS). The Company believes these non-GAAP adjustments provide meaningful information to assist investors in understanding financial results and assessing prospects for future performance as they provide a better baseline for analyzing the ongoing performance of its business by excluding items that may not be indicative of core operating results.

Free cash flow (FCF)

Calculated using total cash provided by operating activities less capital expenditures. The Company believes the presentation of FCF allows investors to evaluate the capacity of the Company's operations to generate free cash flow.

Daily sales

Refers to sales for the period divided by the number of U.S. selling days for the period.

Daily, constant currency sales

Refers to the daily sales adjusted for changes in foreign currency exchange rates.

Daily, organic constant currency sales

Refers to daily sales excluding the sales of certain divested or closed businesses in the comparable prior year period post date of divestiture or closure and changes in foreign currency exchange rates.

Foreign currency exchange

Calculated by dividing current period local currency daily sales by current period average exchange rate and subtracting the current period local currency daily sales divided by the prior period average exchange rate.

U.S. selling days:

2024: Q1-64, Q2-64, Q3-64, Q4-64, FY-256

2025: Q1-63, Q2-64, Q3-64, Q4-64, FY-255

2026: Q1-63, Q2-64, Q3-64, Q4-64, FY-255

As non-GAAP financial measures are not standardized, it may not be possible to compare these measures with other companies' non-GAAP measures having the same or similar names. These non-GAAP measures should not be considered in isolation or as a substitute for reported results. These non-GAAP measures reflect an additional way of viewing aspects of operations that, when viewed with GAAP results, provide a more complete understanding of the business. This press release also includes certain non-GAAP forward-looking information. The Company believes that a quantitative reconciliation of such forward-looking information to the most comparable financial measure calculated and presented in accordance with GAAP cannot be made available without unreasonable efforts. A reconciliation of these non-GAAP financial measures would require the Company to predict the timing and likelihood of future restructurings, asset impairments, and other charges. Neither of these forward-looking measures, nor their probable significance, can be quantified with a reasonable degree of accuracy. Accordingly, a reconciliation of the most directly comparable forward-looking GAAP measures is not provided.

The reconciliations provided reconcile GAAP financial measures to non-GAAP financial measures used in this release: daily sales; daily, organic constant currency sales; free cash flow; adjusted operating margin; and adjustments reflected in the consolidated statements of earnings.
