The Company experienced increases in the majority of the sectors in which it operates, with the most significant growth coming from Network and Communications, Water and Wastewater, Institutional, and Manufacturing and Industrial. These increases were partially offset by a reduction in RPOs within the High-Tech Manufacturing sector, as the Company completed certain semiconductor manufacturing construction projects. Tony Guzzi, Chairman, President, and Chief Executive Officer of EMCOR, commented, “We had an outstanding third quarter, with revenue growth of 16.4% and an exceptional 9.4% operating margin. Our results were driven by strong execution within the diverse sectors we serve as we continue to perform on complex and challenging projects. Our Remaining Performance Obligations are again at an all-time high as we continue to win and earn new business across multiple sectors, geographies, and trades. Our pipeline remains strong, reflecting the demand for our services and supporting our positive outlook for the rest of the year."

Net income for the first nine months of 2025 included $9.4 million, or $6.9 million after taxes, of transaction related costs associated with the acquisition of Miller Electric Company (“Miller Electric”), which closed during the first quarter of 2025. Excluding these transaction costs, non-GAAP net income for the first nine months of 2025 was $845.2 million, or $18.68 per diluted share. Operating income for the first nine months of 2025 was $1.14 billion, or 9.1% of revenues, compared to operating income of $956.3 million, or 8.9% of revenues, for the first nine months of 2024.

Refer to the attached tables for a reconciliation of non-GAAP operating income, non-GAAP operating margin, non-GAAP net income, and non-GAAP diluted earnings per share to the comparable GAAP measures. Selling, general and administrative expenses totaled $1.25 billion, or 10.0% of revenues, for the first nine months of 2025, compared to $1.05 million, or 9.7% of revenues, for the first nine months of 2024.

We are executing well across numerous sectors where demand for our services persists, bolstered by long-term underlying secular trends. Our Electrical and Mechanical Construction segments continue to drive our overall performance with combined year-to-date revenue growth of 23.3% and a combined operating margin of 12.4%. Our performance is further supported by our organic investments in virtual design construction technologies and prefabrication capabilities, which have increased our productivity and efficiency.

Such statements speak only as of October 30, 2025, and EMCOR assumes no obligation to update any such forward-looking statements, unless required by law. These forward-looking statements include statements regarding anticipated future operating and financial performance; financial guidance and projections underlying that guidance; the nature and impact of our remaining performance obligations; the timing of future projects; our ability to support organic growth and balanced capital allocation, including the anticipated impact of our strategic investments; the financial and operational impact of acquisitions and/or dispositions, including the acquisition of Miller Electric Company and pending sale of EMCOR UK and the anticipated use of proceeds from such sale; our competitiveness, market opportunities, and growth prospects; customer trends; and project mix. These forward-looking statements involve risks and uncertainties that could cause actual results to differ materially from those anticipated (whether expressly or implied) by the forward-looking statements. Accordingly, these statements do not guarantee future performance or events. Applicable risks and uncertainties include, but are not limited to, adverse effects of general economic conditions; domestic and international political developments and/or conflicts; changes in the specific markets for EMCOR’s services; weakness of the sectors from which we generate revenues; adverse business conditions; scarcity of skilled labor; productivity challenges; the nature and extent of supply chain disruptions impacting availability and pricing of materials; inflationary trends, including fluctuations in energy costs; the impact of legislation and/or government regulations; adverse effects from the U.S. government shutdown; changes in foreign trade policy including the effect of tariffs; changes in interest rates; the lack of availability of adequate levels of surety bonding; increased competition; the impact of legal proceedings, claims, lawsuits, or governmental investigations; and unfavorable developments in the mix of our business. Certain of the risk factors associated with EMCOR’s business are also discussed in Part I, Item 1A “Risk Factors,” of the Company’s 2024 Form 10-K, and in other reports filed from time to time with the Securities and Exchange Commission and available at www.sec.gov and www.emcorgroup.com. Such risk factors should be taken into account in evaluating our business, including any forward-looking statements. Non-GAAP Measures: This release and related presentation also include certain financial measures that were not prepared in accordance with U.S. generally accepted accounting principles (GAAP). Reconciliations of those non-GAAP financial measures to the most directly comparable GAAP financial measures are included in this release. The Company uses these non-GAAP measures as key performance indicators for the purpose of evaluating performance internally. We also believe that these non-GAAP measures provide investors with useful information with respect to our ongoing operations. Any non-GAAP financial measures presented are not, and should not be viewed as, substitutes for financial measures required by GAAP, have no standardized meaning prescribed by GAAP, and may not be comparable to the calculation of similar measures of other companies. In addition, forecast non-GAAP diluted earnings per share and non-GAAP operating margin for full-year 2025 are forward-looking non-GAAP financial measures. The Company does not provide a reconciliation of forward-looking non-GAAP financial measures to the most directly comparable financial measures calculated and presented in accordance with GAAP on a forward-looking basis because such reconciliations are not accessible with reasonable effort, due to the uncertainty and inherent difficulty of predicting the occurrence and financial impact of adjustments such as transaction costs or gains/losses arising from such transactions that impact comparability and the periods in which such items may be recognized. – MORE – EMCOR GROUP, INC.
