Page 24 © 2025 Helix ESG Non-GAAP Financial MeasuresWe define EBITDA as earnings before income taxes, net interest expense, net other income or expense, and depreciation andamortization expense. Non-cash impairment losses on goodwill and other long-lived assets are also added back if applicable.To arrive at our measure of Adjusted EBITDA, we exclude gains or losses on disposition of assets, acquisition and integrationcosts, gains or losses related to convertible senior notes, the change in fair value of contingent consideration and the generalprovision for (release of) current expected credit losses, if any. We define Free Cash Flow as cash flows from operating activitiesless capital expenditures, net of proceeds from asset sales and insurance recoveries (related to property and equipment), if any.Net debt is calculated as long-term debt including current maturities of long-term debt less cash and cash equivalents andrestricted cash.We use EBITDA, Adjusted EBITDA, Free Cash Flow and Net Debt to monitor and facilitate internal evaluation of theperformance of our business operations, to facilitate external comparison of our business results to those of others in ourindustry, to analyze and evaluate financial and strategic planning decisions regarding future investments and acquisitions, toplan and evaluate operating budgets, and in certain cases, to report our results to the holders of our debt as required by our debtcovenants. We believe that our measures of EBITDA, Adjusted EBITDA, Free Cash Flow and Net Debt provide usefulinformation to the public regarding our operating performance and ability to service debt and fund capital expenditures and mayhelp our investors understand and compare our results to other companies that have different financing, capital and taxstructures. Other companies may calculate their measures of EBITDA, Adjusted EBITDA, Free Cash Flow and Net Debtdifferently from the way we do, which may limit their usefulness as comparative measures. EBITDA, Adjusted EBITDA, FreeCash Flow and Net Debt should not be considered in isolation or as a substitute for, but instead are supplemental to, incomefrom operations, net income, cash flows from operating activities, or other income or cash flow data prepared in accordance withGAAP. Users of this financial information should consider the types of events and transactions that are excluded from thesemeasures. See reconciliation of the non-GAAP financial information presented in this press release to the most directlycomparable financial information presented in accordance with GAAP. We have not provided reconciliations of forward-lookingnon-GAAP financial measures to comparable GAAP measures due to the challenges and impracticability with estimating someof the items without unreasonable effort, which amounts could be significant.
