Third Quarter 2025 Results August 6, 2025

Non-GAAP Measures While we report our financial results in accordance with U.S. GAAP, in this presentation and the associated remarks, we also make reference to certain non-GAAP measures, including: Adjusted EBITDA, Adjusted EBITDA Margin, Free Cash Flow, Net Debt, Net Leverage Ratio, Trailing Twelve Months Covenant Adjusted EBITDA, and Return on Working Capital. We include these non-GAAP financial measures to assist investors in the evaluation of our operating performance, and we believe that presentation of these measures also helps investors because the measures enable better comparisons of our historical results and allow investors to evaluate our performance based on the same metrics that we use to evaluate our performance and trends in our results. These measures should not be considered in isolation or as a substitute for our results as reported under U.S. GAAP, and non-GAAP financial measures as presented by us may not be comparable to other similarly titled measures of other companies because not all companies use identical calculations. These non-GAAP measures are explained and reconciled at the end of this presentation. This presentation and the remarks made during the associated conference call are integrally related and are intended to be presented and understood together. Forward-Looking Statements This presentation contains “forward-looking statements” within the meaning of the securities laws. All statements that reflect our expectations, assumptions or projections about the future, other than statements of historical fact, are forward-looking statements, including, without limitation, forecasts relating to discussions of future operations and financial performance and statements regarding our strategy for growth, future product development, regulatory approvals, competitive position and expenditures.

These forward-looking statements are subject to risks and uncertainties that may change at any time, and actual results or outcomes may differ materially from those that we expected. Forward-looking statements are not guarantees of future performance and are subject to risks, uncertainties, and changes in circumstances that are difficult to predict including, but not limited to: unfavorable macroeconomic conditions including inflationary pressures and higher interest rates; the failure to retain current customers, renew existing customer contracts and obtain new customer contracts, which could result in continued stock volatility and potential future goodwill impairment charges; competition in our industry; our ability to comply with certain financial ratios, tests and covenants in our credit agreement, including the Net Leverage Ratio; our significant indebtedness and ability to meet debt obligations and our reliance on an accounts receivable securitization facility; increases in fuel and energy costs and other supply chain challenges and disruptions, including as a result of ongoing military conflicts in Ukraine and the Middle East; implementation of new or increased tariffs and ongoing changes in U.S. and foreign government trade policies, including potential modifications to existing trade agreements and retaliatory measures by foreign governments; increased operating costs and obstacles to cost recovery due to the pricing and cancellation terms of our support services contracts; a determination by our customers to reduce their outsourcing or use of preferred vendors; the outcome of legal proceedings to which we are or may become subject; risks associated with suppliers from whom our products are sourced; challenge of contracts by our customers; currency risks and other risks associated with international operations, including compliance with a broad range of laws and regulations, including the United States Foreign Corrupt Practices Act; increases in labor costs or inability to hire and retain key or sufficient qualified personnel; continued or further unionization of our workforce; our expansion strategy and our ability to successfully integrate the businesses we acquire and costs and timing related thereto; natural disasters, global calamities, climate change, pandemics, and other adverse incidents; liability resulting from our participation in multiemployer-defined benefit pension plans; liability associated with noncompliance with applicable law or other governmental regulations; laws and governmental regulations including those relating to the environment, wage and hour and government contracting; unanticipated changes in tax law; new interpretations of or changes in the enforcement of the government regulatory framework; a cybersecurity incident or other disruptions in the availability of our computer systems or privacy breaches; stakeholder expectations relating to environmental, social and governance (“ESG”) considerations which may expose us to liabilities and other adverse effects on our business; any failure by Aramark to perform its obligations under the various separation agreements entered into in connection with the separation; and a determination by the IRS that the distribution or certain related transactions are taxable. The above list of factors is not exhaustive or necessarily in order of importance. For additional information on identifying factors that may cause actual results to vary materially from those stated in forward-looking statements, see the Company’s filings with the Securities and Exchange Commission (“SEC”), including “Item 1A-Risk Factors” in the Company’s most recent Annual Report on Form 10-K and in “Item 1A-Risk Factors” of Part II in subsequently-filed Quarterly Reports on Form 10-Q, which are available on the SEC’s website at www.sec.gov.

We calculate recurring rental revenue as base rental revenue for uniforms and workplace supplies, including service charges and the impacts of rebates and other discounts, plus recurring loss and ruin and auxiliary charges such as emblems and embroidery in addition to select consumables we determine to be recurring in nature. Our calculations are approximate and may in some cases rely on estimates which may differ from period to period.

Non-GAAP Definitions ©2025 Vestis. All rights reserved. 15 Vestis reports its financial results in accordance with U.S. GAAP, but in this presentation and the non-GAAP reconciliations that follow, Vestis also uses the following non-GAAP measures: Adjusted EBITDA, Adjusted EBITDA Margin, Free Cash Flow, Net Debt, Net Leverage Ratio, and Trailing Twelve Months Covenant Adjusted EBITDA. Vestis believes that non-GAAP financial measures, both together with and in addition to the corresponding U.S. GAAP financial measure, are important supplemental measures that exclude non-cash or other items that may not be indicative of or are unrelated to Vestis’ core operating results. Vestis uses these non-GAAP financial measures with U.S. GAAP financial measures and other comparable tools to assist in the evaluation of its operating performance. Vestis believes that presentation of these measures also helps investors because the measures enable better comparisons of Vestis’ historical results and allow investors to evaluate Vestis’ performance based on the same metrics that Vestis uses to evaluate its performance and trends in its results. However, these measures have limitations as analytical tools and should not be considered in isolation or as a substitute for Vestis’ results as reported under U.S. GAAP. Specifically, you should not consider these measures as alternatives to revenue, operating income, operating income margin, net income, net income margin or net cash provided by operating activities determined in accordance with U.S. GAAP. These non-GAAP financial measures also should not be considered as measures of cash available to Vestis to invest in the growth of Vestis’ business or cash that will be available to Vestis to meet its obligations. Non-GAAP financial measures as presented by Vestis may not be comparable to other similarly titled measures of other companies because not all companies use identical calculations. These non-GAAP measures are reconciled in the tables at the end of this presentation. Adjusted EBITDA Adjusted EBITDA represents net income adjusted for provision for income taxes; interest expense, net; and depreciation and amortization (EBITDA), further adjusted for share-based compensation expense; severance; separation related charges; securitization fees; loss (gain) on sale of equity investment; third party debt amendment fees; legal reserves and settlements; gains, losses, and other items impacting comparability. Adjusted EBITDA is presented in order to reflect Vestis’ results in a manner that allows a better understanding of operational activities separate from the financial impact of decisions made for the long-term benefit of Vestis and other items impacting comparability between periods. Similar adjustments have been recorded in Adjusted EBITDA for earlier periods and similar types of adjustments can reasonably be expected to be recorded in Adjusted EBITDA in future periods. Adjusted EBITDA Margin Adjusted EBITDA Margin represents Adjusted EBITDA as a percentage of Revenue Free Cash Flow Free Cash Flow represents net cash provided by operating activities adjusted for purchases of property and equipment and other. Free Cash Flow is presented because it relates the operating cash flow of Vestis to the capital that is spent to continue and improve business operations, and indicates the amount of cash generated or used after capital expenditures that can be used for, among other things, investment in the Vestis business, strengthening the balance sheet, and repayment of debt obligations. Free cash flow does not represent the residual cash flow available for discretionary expenditures since there may be other nondiscretionary expenditures that are not deducted from the measure. Net Leverage Ratio, Net Debt, Covenant Adjusted EBITDA, Covenant Adjusted EBITDA Margin and Trailing Twelve Months Covenant Adjusted EBITDA Net Leverage Ratio is defined in Vestis’ credit agreement and is calculated as consolidated total indebtedness in excess of unrestricted cash (referred to herein as “Net Debt”), divided by the Trailing Twelve Months Covenant Adjusted EBITDA. Net Debt represents total principal debt outstanding, letters of credit outstanding, and finance lease obligations, less cash and cash equivalents. Covenant Adjusted EBITDA represents Adjusted EBITDA, as further modified by certain items specifically permitted under the credit agreement to assess compliance with its financial covenants. Covenant Adjusted EBITDA Margin is Covenant Adjusted EBITDA as a percentage of Revenue. Trailing Twelve Months Covenant Adjusted EBITDA represents Covenant Adjusted EBITDA for the preceding four fiscal quarters. Vestis believes that Net Leverage Ratio and its components are useful to investors because they are indicators of Vestis’ ability to meet its future financial obligations and are measures that are frequently used by investors and creditors. Return on Working Capital Return on working capital is calculated by dividing trailing twelve months Adjusted EBITDA with operating working capital.
