For the third quarter of 2026, revenues totaled a quarterly record of $5.54 billion, an increase of 28.8%, compared to revenues of $4.30 billion for the third quarter of 2025. On an organic basis, when adjusting for incremental acquisition contribution and the impact of the sale of the Company's United Kingdom operations in 2025, third quarter revenues increased by 25.5%.

Net income for the third quarter of 2026 was $399.9 million, or $9.04 per diluted share, compared to net income of $295.4 million, or $6.57 per diluted share, for the third quarter of 2025. Net income for the third quarter of 2026 included a non-cash impairment loss on identifiable intangible assets of $34.0 million, or $24.7 million after taxes.

Refer to the attached tables for a reconciliation of organic revenue growth, 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 for the third quarter of 2026 totaled $528.4 million, or 9.5% of revenues, compared to $429.6 million, or 10.0% of revenues, for the third quarter of 2025.

The Company's income tax rate for the third quarter of 2026 was 27.2%, compared to 27.5% for the third quarter of 2025.

Remaining performance obligations (“RPOs”) as of September 30, 2026 were a record $18.57 billion, compared to $12.61 billion as of September 30, 2025, an increase of $5.96 billion year-over-year, due to new contract awards across the majority of the sectors in which the Company operates. The most significant RPO growth occurred within the Network and Communications market sector as mission critical facilities continue to require substantial electrical infrastructure and increasingly sophisticated cooling systems. The Company also benefited from a broad range of customer investments across other large end markets, including the Healthcare, Water and Wastewater, Institutional, and Manufacturing and Industrial sectors.

Tony Guzzi, Chairman, President, and Chief Executive Officer of EMCOR, commented, “EMCOR delivered another quarter of exceptional growth, margin performance, operating cash flow, and capital allocation. Our strong revenue growth, coupled with excellent field execution and improved SG&A leverage, resulted in meaningful expansion of our operating margin. We continued to outgrow the broader non-residential construction market, reinforcing the depth of demand for our services."

EMCOR Group's third quarter conference call will be broadcast live via the internet today, Thursday, October 29, at 10:30 AM Eastern Daylight Time and can be accessed through the Company's website at www.emcorgroup.com.

About EMCOR

A Fortune 500 company and a member of the S&P 500, EMCOR Group, Inc. is a leader in mechanical and electrical construction services, industrial and energy infrastructure, and building services. This press release and other press releases may be viewed at the Company’s website at www.emcorgroup.com. EMCOR routinely posts information that may be important to investors on the landing page of the Company's website and in the “Investor Relations” section of the website at www.emcorgroup.com/investor-relations. Investors and potential investors are encouraged to consult the EMCOR website regularly for important information about EMCOR.

Forward Looking Statements:

This release and related presentation contain forward-looking statements. Such statements speak only as of October 29, 2026, 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; 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, government regulations, permitting requirements, moratoriums, or other governmental actions; 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 2025 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 2026 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 impairments that impact comparability and the periods in which such items may be recognized.
