Changes to Operating and Reportable Segments

Beginning with the fourth quarter of 2025, we are reporting results under three operating and reportable segments. This shift in reportable segments reflects how our leadership oversees and manages the business. Our three operating and reportable segments consist of the following:

Uniform & Facility Service Solutions

First Aid & Safety Solutions

Other

To assist investors, we have provided certain recast unaudited historical financial and operational data that is on a basis consistent with our revised segment structure. This data can be found both in our Form 8-K filed on October 17, 2025 and on our Investor Relations webpage under "News Releases." These changes only affect segment allocation of results and do not revise or restate our previously reported consolidated financial statements.

Q4 2025 Segment Financial Highlights

Uniform & Facility Service Solutions

The costs we incurred related to the Key Initiatives were recorded to the Uniform & Facility Service Solutions’ segment, and decreased both the Uniform & Facility Service Solutions’ operating and Adjusted EBITDA margins for the fourth quarters of fiscal 2025 and 2024 by 0.2% and 0.3%, respectively.

The segment’s operating and Adjusted EBITDA margins in the fourth quarter of fiscal 2025 were down slightly from the fourth quarter of fiscal 2024, which benefited from the extra week of operations. In addition, the quarterly results reflect additional investments in accelerating growth, improving customer retention and our digital transformation.

First Aid & Safety Solutions

The segment’s results continue to reflect the investments we are making in our First Aid van business.

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 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:
