UNIFIRST ANNOUNCES FINANCIAL RESULTS FOR THE SECOND QUARTER OF FISCAL 2025

Wilmington, MA – April 2, 2025 – UniFirst Corporation (NYSE: UNF) (the “Company,” “UniFirst” or “we”) today reported results for its second quarter ended March 1, 2025 as compared to the corresponding period in the prior fiscal year:

Q2 2025 Financial Highlights

The Company's financial results for the second quarter of fiscal 2025 and 2024 included approximately $1.9 million and $3.2 million, respectively, of costs directly attributable to its customer relationship management (“CRM”) computer system and enterprise resource planning (“ERP”) projects. The Company refers to the CRM and ERP projects together as its “Key Initiatives”. The effect of these items on the second quarter of fiscal 2025 and 2024 combined to decrease:

Steven Sintros, UniFirst President and Chief Executive Officer, said, “We are pleased with the results from our second quarter, which were largely in line with our expectations. We are excited that our investments in the business are starting to show returns in several areas, including improved profitability, cash flow and overall operational execution. I want to sincerely thank all of our Team Partners who continue to Always Deliver for each other and our customers as we strive towards our vision of being universally recognized as the best service provider in the industry. …all while living our mission of Serving the People Who do the Hard Work.”

Segment Reporting Highlights

Core Laundry Operations

The costs we incurred related to the Key Initiatives were recorded to the Core Laundry Operations’ segment, and decreased both the Core Laundry Operations’ operating and Adjusted EBITDA margins for the second quarters of fiscal 2025 and 2024 by 0.3% and 0.6%, respectively.

The segment's operating and Adjusted EBITDA margin increases were primarily due to lower merchandise and production costs as a percentage of revenues. These were partially offset by higher healthcare claims expense and selling and administrative costs as a percentage of revenues in the second quarter of fiscal 2025.

Specialty Garments

Balance Sheet and Capital Allocation

Financial Outlook

Mr. Sintros continued, “At this time, we expect our revenues for fiscal 2025 to be between $2.422 billion and $2.432 billion which reflects the anticipated negative impact of the Canadian Dollar exchange rate compared to our original expectations. We further expect that our diluted earnings per share will be between $7.30 and $7.70, which reflects improved anticipated operating income in our Core Laundry Operations and an assumption that our Key Initiative costs in fiscal 2025 will approximate $12.0 million, revised down from prior estimates."

Please note the guidance does not include the impact of any future share buybacks or unexpected events affecting the economy generally.

Reconciliation of GAAP to Non-GAAP Financial Measures

The Company reports its consolidated financial results in accordance with generally accepted accounting principles (“GAAP”). To supplement the Company’s consolidated financial results in this press release, the Company also presents Adjusted EBITDA and Adjusted EBITDA margin, which are non-GAAP financial measures. The Company defines Adjusted EBITDA as net income before interest, income taxes, depreciation and amortization, further adjusted for share-based compensation expense, acquisition costs, executive transition costs and other items impacting the comparability of the Company’s underlying operating performance between periods. Adjusted EBITDA margin is defined as Adjusted EBITDA for a period divided by revenue for the same period.

The Company believes these non-GAAP financial measures provide useful supplemental information regarding the performance of the Company and its segments to both management and investors. In addition, by excluding certain items, these non-GAAP financial measures enable management and investors to further evaluate the underlying operating performance of the Company.

Supplemental reconciliations of the Company’s consolidated net income on a GAAP basis to Adjusted EBITDA and Adjusted EBITDA margin, are presented in the following table. Investors are encouraged to review the reconciliations of the non-GAAP financial measures to their most directly comparable GAAP financial measures, which are provided below. Adjusted EBITDA and Adjusted EBITDA margin should be considered in addition to, and not as substitutes for, or in isolation from, measures prepared in accordance with GAAP.

The Company does not allocate its provision for income taxes to its business segments and as a result, presents it in a separate column in the following tables.
