MELVILLE, N.Y. and DAVIDSON, N.C. (JANUARY 7, 2026) - 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 2026 first quarter ended November 29, 2025.

Martina McIsaac, President and Chief Executive Officer, said, “We began the fiscal year on solid footing by executing on the continued momentum from our recent growth initiatives. This resulted in average daily sales growth at the midpoint of our outlook and approximately 180 basis points above the Industrial Production Index, despite headwinds related to the government shutdown of roughly 100 basis points. As a result of our improving levels of execution and focus on optimizing costs, we returned to profitable growth in the fiscal first quarter.”

Greg Clark, Vice President and Interim Chief Financial Officer, added, “We successfully capitalized on growth by delivering 10 basis points of operating margin expansion, or 40 basis points on an adjusted basis year over year and towards the higher end of our guidance range. This resulted in double digit improvement in earnings per share on both a reported and adjusted basis.”

McIsaac concluded, “Looking ahead, I am encouraged by our performance early in the fiscal year. We will continue advancing the benefits from our growth initiatives and identifying areas to optimize our cost to serve that supported our return to operating margin expansion this quarter. The timing of holidays created a soft start to the fiscal second quarter, which is affecting our outlook for average daily sales in the quarter, but I remain confident in profitable growth remaining a trend throughout fiscal 2026 and beyond as this momentum continues.”

•Depreciation and amortization expense of ~$95M-$100M

•Interest and other expense of ~$35M

•Capital expenditures of ~$100M-$110M

•Free cash flow conversion1 of ~90%

•Tax rate of ~24.5%-25.5%

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 and share reclassification litigation costs, 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, including adjusted operating margin and free cash flow conversion. 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, 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.

•Free Cash Flow (“FCF”) and Free Cash Flow Conversion (“FCF Conversion”)

FCF is a non-GAAP financial measure. FCF is used in addition to and in conjunction with results presented in accordance with GAAP, and FCF should not be relied upon to the exclusion of GAAP financial measures. Management strongly encourages investors to review our financial statements and publicly-filed reports in their entirety and to not rely on any single financial measure. FCF, which we reconcile to “Net cash provided by operating activities,” is cash flow from operations reduced by “Expenditures for property, plant and equipment”. We believe that FCF, although similar to cash flow from operations, is a useful additional measure since capital expenditures are a necessary component of ongoing operations. Management also views FCF, as a measure of the Company’s ability to reduce debt, add to cash balances, pay dividends, and repurchase stock. FCF has limitations due to the fact that it does not represent the residual cash flow available for discretionary expenditures. For example, FCF does not incorporate payments made on finance lease obligations or required debt service payments. In addition, different companies define FCF differently. Therefore, we believe it is important to view FCF as a complement to our entire consolidated statements of cash flows. FCF Conversion is useful to investors for the foregoing reasons and as a measure of the rate at which the Company converts its net income reported in accordance with GAAP to cash inflows, which helps investors assess whether the Company is generating sufficient cash flow to provide an adequate return.

•Results Excluding Restructuring and Other Costs and Share Reclassification Litigation Costs

In calculating certain non-GAAP financial measures, we exclude items such as restructuring and other costs and share reclassification litigation costs, 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.
