Revenue

Sales in the quarter increased 4.3% compared to the third quarter of 2023. Normalizing for one more selling day in the current year quarter, foreign currency exchange and the Company's 2023 divestiture of its subsidiary, E & R Industrial Sales, Inc., sales on a daily, organic constant currency basis increased 4.0%compared to the third quarter of 2023.

In the High-Touch Solutions - N.A. segment, sales were up 3.3%, or up 2.5% on a daily, organic constant currency basis, compared to the third quarter of 2023. Increased revenue for the segment was driven by growth in all geographies and included broad-based gains across most customer end markets. In the Endless Assortment segment, sales were up 8.1%, or 11.5% on a daily, constant currency basis, compared to the third quarter of 2023. Revenue growth for the segment was driven by core B2B customers at Zoro and strong performance across MonotaRO, most notably with Enterprise customers.

Gross Profit Margin

Gross profit margin was 39.2% in the third quarter of 2024, a decline of 10 basis points from the third quarter of 2023.

In the High-Touch Solutions - N.A. segment, 2024 third quarter gross profit margin was 41.6%, a 10 basis point decline compared the prior year quarter as various factors largely offset. In the Endless Assortment segment, gross profit margin declined by 10 basis points from the third quarter of 2023 driven primarily by product and customer mix headwinds.

Earnings

For the third quarter of 2024, total company operating earnings were $686 million, up 2.8% compared to the third quarter of 2023. Operating margin in the quarter was 15.6%, a 30-basis point decrease from the third quarter of 2023. Continued investment in demand generating activities, as well as annual merit increases in High-Touch Solutions - N.A., were partially offset by strong leverage across Endless Assortment.

Diluted earnings per share for the third quarter of 2024 were $9.87, up 4.7% compared to the third quarter of 2023. The increase was driven by sales growth and fewer shares outstanding.

Tax Rate

The third quarter 2024 effective tax rate was 24.8%, compared to 24.4% in the third quarter of 2023.

Cash Flow

During the third quarter of 2024, the Company generated $611 million of cash flow from operating activities driven by solid net earnings. Working capital in the period had a neutral impact on operating cash flow. The Company invested $88 million in capital expenditures, resulting in free cash flow of $523 million. During the quarter, the Company returned $328 million to Grainger shareholders through dividends and share repurchases.

SUPPLEMENTAL INFORMATION - RECONCILIATION OF GAAP TO NON-GAAP

FINANCIAL MEASURES (Unaudited)

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 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 businesses in the comparable prior year period 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:

2023: Q1-64, Q2-64, Q3-63, Q4-63, FY-254

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

2025: 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 below reconciles 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.
