Investor Presentation May/June 2025 Exhibit 99.1

Forward-Looking Statements 2 This presentation, and oral comments that Everus may make, contain or incorporate by reference certain “forward-looking statements” within the meaning of the securities laws. All statements that reflect Everus’ expectations, assumptions or projections about the future, other than statements of historical facts, including, without limitation, statements regarding plans, trends, objectives, goals, business and growth strategies, market potential, our 4EVER strategy, future performance, financial guidance, long-term targets and other matters are consider forward-looking statements. The words “believe,” “expect,” “estimate,” “could,” “should,” “would,” “intend,” “may,” “plan,” “predict,” “seek,” “anticipate,” “project” and similar expressions generally identify forward-looking statements, which speak only as of the date the statements were made. In particular, information included within this presentation contains forward-looking statements. The matters discussed in this presentation are subject to risks, uncertainties and other factors that could cause actual results to differ materially from those projected, anticipated or implied in the forward looking statements. Although Everus believes that the expectations reflected in any forward-looking statements it makes are based on reasonable assumptions as of the date they are made, it can give no assurance that the expectation will be attained and it is possible that actual results may differ materially from those indicated by these forward-looking statements due to a variety of risks and uncertainties. For additional information on identifying factors that may cause actual results to vary materially from those stated in forward-looking statements, see the discussion under “Item 1A. Risk Factors” in the Company's 2024 Annual Report on Form 10-K and subsequent filings with the Securities and Exchange Commission. You should read this presentation completely and with the understanding that actual future results may be materially different from expectations. All forward-looking statements made in this presentation are qualified by these cautionary statements. These forward-looking statements are made only as of the date of this presentation, and Everus does not undertake any obligation, other than as may be required by law, to update or revise any forward-looking or cautionary statements to reflect changes in assumptions, the occurrence of events, unanticipated or otherwise, and changes in future operating results over time or otherwise. Comparisons of results for current and any prior periods are not intended to express any future trends, or indications of future performance, unless expressed as such, and should only be viewed as historical data. All financial information presented in this presentation has been prepared in U.S. dollars in accordance with generally accepted accounting principles in the United States (“GAAP”), except for the presentation of the following non-GAAP financial measures: organic revenue, organic revenue growth, EBITDA, EBITDA margin, free cash flow, net debt and net leverage, and, in some cases, applicable measures by segment. Organic revenue is most comparable to the GAAP measure of revenue and is defined as the difference between current year and prior year revenues less the impact of acquired and divested companies in the past 12 months. Organic revenue growth is most comparable to the GAAP measure of revenue growth and is calculated by dividing organic revenue by prior year revenues. EBITDA is most comparable to the GAAP measure of net income and is defined as net income before interest expense, net of interest income, income taxes and depreciation and amortization. EBITDA margin is most comparable to the GAAP measure of net income margin and is defined as EBITDA as a percentage of operating revenues. Free cash flow is most comparable to the GAAP measure of cash flows provided by (used in) operating activities. Free cash flow is defined as net cash provided by (used in) operating activities less net capital expenditures. Net debt and net leverage are most comparable to the GAAP measure of total debt. Net debt is calculated by adding unamortized debt issuance costs to the total debt balance presented on the balance sheet, less any unrestricted cash. Net leverage is calculated by dividing net debt divided by EBITDA, as defined. Our non-GAAP financial measures are not standardized; therefore, it may not be possible to compare them with other companies’ measures of organic revenue, organic revenue growth, EBITDA, EBITDA margin, free cash flow, net debt and net leverage having the same or similar names. Everus presents organic revenue, organic revenue growth, EBITDA, EBITDA margin, free cash flow, net debt and net leverage, and, in some cases, applicable measures by segment, in this presentation because it believes such measures, in addition to corresponding GAAP measures, provide investors with additional information to measure Everus’ performance and liquidity. These non-GAAP financial measures are not intended as alternatives to GAAP financial measures. Everus uses organic revenue, organic revenue growth, EBITDA and EBITDA margin, as well as the comparable GAAP measures of revenue, revenue growth, net income and net income margin, as indicators of Everus’ operating performance. Everus uses free cash flow as well as the comparable GAAP measure of cash flows provided by (used in) operating activities, as a measure of cash available to Everus to invest in the growth of Everus’ business or that will be available to Everus to meet its obligations. Everus uses net debt and net leverage as well as the comparable GAAP measure of total debt to provide a measure of how quickly Everus could repay its debt if net debt and EBITDA were constant. Net leverage also provides insight into Everus' borrowing capacity and leverage ratio. Reconciliations of the non-GAAP measures used to their respective most directly comparable GAAP measure can be found in the Appendix.

Non-GAAP Financial Measures 25 We are unable to reconcile long-term organic revenue, organic revenue growth, EBITDA and net leverage to their respective nearest U.S. GAAP measure because we are unable to predict the timing of these adjustments with a reasonable degree of certainty. By their very nature, non-GAAP adjustments are difficult to anticipate with precision because they are generally associated with unexpected and unplanned events that impact our company and our financial results. Therefore, we are unable to provide reconciliations of these non-GAAP financial measures without unreasonable efforts.
