MELVILLE, N.Y. and DAVIDSON, N.C. (JULY 1, 2025) - MSC INDUSTRIAL SUPPLY CO. (NYSE: MSM) (“MSC,” “MSC Industrial,” the “Company,” “we,” “us,” or “our”), a leading North American distributor of a broad range of metalworking and maintenance, repair and operations (MRO) products and services, today reported financial results for its fiscal 2025 third quarter ended May 31, 2025.

Erik Gershwind, Chief Executive Officer, said, “We delivered fiscal third quarter results that were in line with our expectations for both average daily sales and operating margins. While we certainly have plenty of room for improvement, we saw early signs of progress in each of our three critical strategic areas of focus — reenergizing the core customer, maintaining momentum in high-touch solutions, and optimizing our cost to serve.”

Kristen Actis-Grande, Executive Vice President and Chief Financial Officer, added, “Average daily sales declined 0.8% year-over-year, slightly ahead of the midpoint of our outlook, driven by benefits from price and improving performance in volumes. During the fiscal third quarter, we leveraged our strong free cash flow performance and balance sheet to return approximately $56 million to shareholders in the form of dividends and share repurchases, resulting in approximately $181 million returned to shareholders fiscal year-to-date.”

Gershwind concluded, “The fiscal third quarter included encouraging data points, such as core customer sequential improvement, continued momentum in our high-touch solutions and a building productivity pipeline. Looking longer term, we remain steadfast in our commitment to restoring performance consistent with our long-term objectives of growing to 400 basis points or more above the IP Index and expanding operating margins to the mid-teens.”

•Depreciation and amortization expense of ~$90M-$95M

•Interest and other expense of ~$45M

•Capital expenditures of ~$100M-$110M

•Free cash flow conversion1 of ~120%

In addition, statements which refer to expectations, projections or other characterizations of future events or circumstances, statements involving a discussion of strategy, plans or intentions, statements about management’s assumptions, projections or predictions of future events or market outlook and any other statement other than a statement of present or historical fact are forward-looking statements. The inclusion of any statement in this press release does not constitute an admission by MSC or any other person that the events or circumstances described in such statement are material.

Accordingly, future results may differ materially from historical results or from those discussed or implied by these forward-looking statements. Given these risks and uncertainties, the reader should not place undue reliance on these forward-looking statements. These risks and uncertainties include, but are not limited to, the following: general economic conditions in the markets in which we operate; changing customer and product mixes; volatility in commodity, energy and labor prices, and the impact of prolonged periods of low, high or rapid inflation; competition, including the adoption by competitors of aggressive pricing strategies or sales methods; industry consolidation and other changes in the industrial distribution sector; the applicability of laws and regulations relating to our status as a supplier to the U.S. government and public sector; the credit risk of our customers; our ability to accurately forecast customer demands; interruptions in our ability to make deliveries to customers; supply chain disruptions; our ability to attract and retain sales and customer service personnel; the risk of loss of key suppliers or contractors or key brands; changes to trade policies or trade relationships, including tariff policies; risks associated with opening or expanding our customer fulfillment centers; our ability to estimate the cost of healthcare claims incurred under our self-insurance plan; interruption of operations at our headquarters or customer fulfillment centers; products liability due to the nature of the products that we sell; impairments of goodwill and other indefinite-lived intangible assets; the impact of climate change; operating and financial restrictions imposed by the terms of our material debt instruments; our ability to access additional liquidity; the significant influence that our principal shareholders will continue to have over our decisions; our ability to execute on our E-commerce strategies and maintain our digital platforms; costs associated with maintaining our information technology (“IT”) systems and complying with data privacy laws; disruptions or breaches of our IT systems or violations of data privacy laws, including such disruptions or breaches in connection with our E-commerce channels; risks related to online payment methods and other online transactions; our ability to remediate a material weakness in our internal control over financial reporting and to maintain effective internal control over financial reporting and our disclosure controls and procedures in the future; the retention of key management personnel; litigation risk due to the nature of our business; failure to comply with environmental, health, and safety laws and regulations; and our ability to comply with, and the costs associated with, social and environmental responsibility policies.

Additional information concerning these and other risks is described under “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual and Quarterly Reports on Forms 10-K and 10-Q, respectively, and in the other reports and documents that we file with the United States Securities and Exchange Commission. We expressly disclaim any obligation to update any of these forward-looking statements, except to the extent required by applicable law.

To supplement MSC’s unaudited selected financial data presented consistent with accounting principles generally accepted in the United States (“GAAP”), the Company discloses certain non-GAAP financial measures, including non-GAAP operating expenses, non-GAAP income from operations, non-GAAP operating margin, non-GAAP provision for income taxes, non-GAAP net income and non-GAAP diluted earnings per share, that exclude items such as restructuring and other costs, loss on sale of property, share reclassification litigation costs, share reclassification costs (prior year) and acquisition-related costs (prior year), and tax effects.

These non-GAAP financial measures are not presented in accordance with GAAP or alternatives for GAAP financial measures and may be different from similar non-GAAP financial measures used by other companies. The presentation of this additional information is not meant to be considered in isolation or as a substitute for the most directly comparable GAAP financial measure and should only be used to evaluate MSC’s results of operations in conjunction with the corresponding GAAP financial measure.

This press release also includes certain forward-looking information that is not presented in accordance with GAAP. The Company believes that a quantitative reconciliation of such forward-looking information to the most directly comparable financial measures calculated and presented in accordance with GAAP cannot be made available without unreasonable efforts because a reconciliation of these non-GAAP financial measures would require the Company to predict the timing and likelihood of potential future events such as restructurings, M&A activity, capital expenditures and other infrequent or unusual gains and losses. Neither the timing or likelihood of these events, nor their probable significance, can be quantified with a reasonable degree of accuracy. Accordingly, a reconciliation of such forward-looking information to the most directly comparable GAAP financial measures is not provided.

•Results Excluding Restructuring and Other Costs, Loss on Sale of Property, Share Reclassification Litigation Costs, Share Reclassification Costs (prior year) and Acquisition-Related Costs (prior year)

In calculating certain non-GAAP financial measures, we exclude items such as restructuring and other costs, loss on sale of property, share reclassification litigation costs, share reclassification costs (prior year) and acquisition-related costs (prior year), and tax effects. Management makes these adjustments to facilitate a review of the Company’s operating performance on a comparable basis between periods, for comparing with forecasts and strategic plans, for identifying and analyzing trends in the Company’s underlying business and for benchmarking performance externally against competitors. We believe that investors benefit from seeing results from the perspective of management in addition to seeing results presented in accordance with GAAP for the same reasons and purposes for which management uses such non-GAAP financial measures.
