Emcor Group, Inc,
Fiscal Year 2025 Q2.

Gross profit margin19.4 %18.7 %19.0 %17.9 % Our gross profit for the three months ended June 30, 2025 was $833.8 million, or 19.4% of revenues, compared to gross profit of $684.0 million, or 18.7% of revenues, for the three months ended June 30, 2024. Gross profit for the six months ended June 30, 2025 was $1,556.5 million, or 19.0% of revenues, compared to gross profit of $1,273.3 million, or 17.9% of revenues, for the six months ended June 30, 2024. The year-over-year increases in gross profit and the expansion in gross profit margin were driven by both of our United States construction segments, as well as our United States building services segment, in each case due to an improved revenue mix and excellent project execution. Our gross profit for the three and six months ended June 30, 2025 included incremental acquisition contribution of $43.7 million and $85.4 million, respectively, net of amortization expense attributable to identifiable intangible assets of $7.0 million and $12.4 million, respectively.

SG&A margin9.7 %9.6 %10.1 %9.6 % Our selling, general and administrative expenses for the three months ended June 30, 2025 were $418.6 million, or 9.7% of revenues, compared to selling, general and administrative expenses of $351.2 million, or 9.6% of revenues, for the three months ended June 30, 2024. Selling, general and administrative expenses for the six months ended June 30, 2025 were $822.5 million, or 10.1% of revenues, compared to selling, general and administrative expenses of $680.5 million, or 9.6% of revenues, for the six months ended June 30, 2024. Selling, general and administrative expenses for the three and six months ended June 30, 2025 included $34.4 million and $62.0 million, respectively, of incremental expenses directly related to companies acquired, including amortization expense attributable to identifiable intangible assets of $5.5 million and $10.6 million, respectively. Included in selling, general and administrative expenses for the six months ended June 30, 2025 were $9.4 million of transaction related costs incurred during the first quarter in connection with the acquisition of Miller Electric. Excluding incremental expenses resulting from acquisitions, our selling, general and administrative expenses for the three and six months ended June 30, 2025 increased by $32.9 million and $80.0 million, respectively, primarily as a result of greater: (a) incentive compensation expense, predominantly within our United States construction segments, given higher projected annual operating results, (b) salaries and related employment expenses, due to additional headcount to support our organic revenue growth as well as annual cost of living adjustments, and (c) computer hardware and software costs due to various information technology and cybersecurity initiatives currently in process. The 50 basis point increase in our SG&A margin for the six months ended June 30, 2025 was primarily due to: (a) improved gross profit and gross profit margin, which resulted in the above referenced increase in incentive compensation expense across certain of our operating subsidiaries, (b) a decrease in revenues, without a commensurate decrease in selling, general and administrative expenses, within our United States building services and United States industrial services segments, and (c) the impact of the $9.4 million of transaction related costs referenced above. 35

Other items For the three months ended June 30, 2025, net interest expense was $3.2 million, compared to net interest income of $6.1 million for the three months ended June 30, 2024. For the six months ended June 30, 2025, net interest income was $2.1 million, compared to net interest income of $13.6 million for the six months ended June 30, 2024. These year-over-year fluctuations were a result of an increase in interest expense, given the outstanding borrowings under our revolving credit facility during the first half of 2025, coupled with a reduction in interest income due to a lower average daily invested cash balance. For the three and six months ended June 30, 2025, our income tax provision was $109.9 million and $193.4 million, respectively, compared to an income tax provision of $91.6 million and $162.1 million for the three and six months ended June 30, 2024, respectively. Our effective income tax rate for the three and six months ended June 30, 2025 was 26.7% and 26.3%, respectively, compared to an effective income tax rate for the three and six months ended June 30, 2024 of 27.0% and 26.7%, respectively. Refer to Note 9 - Income Taxes of the notes to consolidated financial statements for further discussion regarding our income tax provision and effective income tax rate.

Impact of Acquisitions In order to provide a more meaningful period-over-period discussion of our operating results, we may discuss amounts generated or incurred (revenues, gross profit, selling, general and administrative expenses, and operating income) from companies acquired. These amounts reflect the acquired companies' operating results in the current reported period only for the time period these entities were not owned by EMCOR in the comparable prior reported period. For further discussion regarding our acquisitions, refer to Note 4 - Acquisitions of Businesses of the notes to consolidated financial statements. During the first quarter of 2025, we completed the acquisition of Miller Electric Company ("Miller Electric"), a leading electrical contractor predominantly operating across the Southeastern United States, for total consideration of approximately $868.6 million. The results of operations for Miller Electric have been included within our United States electrical construction and facilities services segment. In addition, during the first half of 2025, we acquired three companies for upfront consideration of $38.8 million, inclusive of customary working capital adjustments. Such acquisitions include: (a) a company in the Midwestern region of the United States that provides building automation controls and solutions to commercial, institutional, and industrial customers, (b) a company that adds capabilities to our national fire protection offerings, and (c) a provider of mechanical construction and maintenance services in the Western region of the United States. The results of operations of these three companies have been included within our United States mechanical construction and facilities services segment. We acquired seven companies during calendar year 2024 for upfront consideration of $231.1 million, inclusive of customary working capital adjustments. These acquisitions are comprised of: (a) an electrical contractor in the Southeast region of the United States, that has been included in our United States electrical construction and facilities services segment, (b) two companies that have been included within our United States mechanical construction and facilities services segment, including: (i) a leading plumbing services provider in the Southeast region of the United States and (ii) a full service provider of mechanical construction and maintenance services in Central Texas, (c) three companies that have been included in our United States building services segment, including: (i) a provider of building automation and controls solutions in the Northeast region of the United States, (ii) a mechanical services company in the Western region of the United States, and (iii) a mechanical services company in the Eastern region of the United States, and (d) an instrumentation and electrical contractor, that has been included in our United States industrial services segment, which provides electrical, automation, digital integration, and fabrication services to various energy sector and process equipment customers.

Operating margin for the three months ended June 30, 2025 was 9.6% compared to an operating margin of 9.1% for the three months ended June 30, 2024. For the six months ended June 30, 2025, operating income was $734.0 million, an increase of $141.2 million compared to operating income of $592.8 million for the six months ended June 30, 2024. Operating margin for the six months ended June 30, 2025 was 9.0% compared to an operating margin of 8.3% for the six months ended June 30, 2024. As described in more detail below, these increases in profitability were predominantly a result of improved operating performance within our United States construction segments, due to a more favorable mix of work and better project execution, including enhanced productivity, due in part to investments in virtual design and construction, prefabrication, and automation. Operating income for the three and six months ended June 30, 2025 included incremental acquisition contribution of $9.2 million and $23.5 million, respectively, net of amortization expense attributable to identifiable intangible assets of $12.5 million and $23.0 million, respectively. 36 Operating income of our United States electrical construction and facilities services segment was $157.6 million, or 11.8% of revenues, for the three months ended June 30, 2025, compared to $88.6 million, or 11.1% of revenues, for the three months ended June 30, 2024. Operating income of this segment for the six months ended June 30, 2025 was $293.7 million, or 12.1% of revenues, compared to $180.2 million, or 11.5% of revenues, for the six months ended June 30, 2024. Operating income and operating margin of this segment for both 2025 periods benefited from greater gross profit and gross profit margin due to an increase in revenues, excellent project execution, and a more favorable mix of work. While the most significant increase in gross profit was generated within the network and communications market sector, this segment additionally experienced increases within the majority of the other market sectors in which we operate, generally in line with the revenue trends described above. Largely driven by Miller Electric, this segment's operating income for the three and six months ended June 30, 2025 included incremental acquisition contribution of $9.8 million and $21.8 million, respectively, net of amortization expense attributable to identifiable intangible assets of $11.4 million and $19.4 million, respectively. Our United States mechanical construction and facilities services segment's operating income for the three months ended June 30, 2025 was $238.7 million, or 13.6% of revenues, compared to operating income of $213.4 million, or 12.9% of revenues, for the three months ended June 30, 2024. Operating income of this segment for the six months ended June 30, 2025 was $425.5 million, or 12.8% of revenues, compared to $364.2 million, or 11.8% of revenues, for the six months ended June 30, 2024. Similar to our United States electrical construction and facilities services segment, this improved performance for both 2025 periods was a result of greater gross profit and gross profit margin due to an increase in revenues, excellent project execution, and a more favorable mix of work. From a market sector perspective, this segment also experienced greater profitability across a number of the sectors in which we operate, with the most significant increase in gross profit coming from network and communications. This segment's operating income for the six months ended June 30, 2025 included incremental acquisition contribution of $2.3 million, net of amortization expense attributable to identifiable intangible assets of $2.1 million. Partially offsetting this increased profitability was a decrease in gross profit from the commercial market sector, primarily as a result of the reduced revenues previously referenced. Operating income of our United States building services segment was $50.0 million, or 6.3% of revenues, for the three months ended June 30, 2025 compared to $46.8 million, or 6.0% of revenues, for the three months ended June 30, 2024. Operating income of this segment for the six months ended June 30, 2025 was $86.5 million, or 5.6% of revenues, compared to $80.3 million, or 5.1% of revenues, for the six months ended June 30, 2024. For both 2025 periods, this segment's mechanical services division continued to produce strong margins across its portfolio of HVAC retrofits, building automation and controls projects, and repair service work orders. Headwinds faced in this segment's commercial site-based services and government site-based services divisions, given the loss of the previously referenced facilities maintenance contracts, partially offset such profitability during the first six months of 2025. The results of this segment for the six months ended June 30, 2024 included an $11.0 million reserve for a specific customer bankruptcy within its commercial site-based services division, which negatively impacted the segment's operating margin by 70 basis points in such prior year period.

When compared to December 31, 2024, remaining performance obligations increased by approximately $1.81 billion. Acquisitions, notably Miller Electric, account for approximately $0.96 billion of such increase, with the remaining growth resulting from new contract awards across all of our reportable segments. From a market sector perspective, we experienced growth within the majority of the sectors we serve, with the most significant increases within: (a) network and communications, largely as a result of several data center construction contracts, (b) institutional, (c) manufacturing and industrial, due to certain: (i) food processing construction projects and (ii) renewable energy projects, (d) commercial, including various warehousing and distribution projects, and (e) hospitality and entertainment. See Note 3 - Revenue from Contracts with Customers of the notes to consolidated financial statements for further disclosure regarding our remaining performance obligations.

Cash Flows The following table presents a summary of our operating, investing, and financing cash flows (in thousands): For the six months ended June 30,

$(853,234)$18,448 During the six months ended June 30, 2025, our cash balance, including cash equivalents and restricted cash, decreased by approximately $853.2 million from $1,340.4 million at December 31, 2024 to $487.2 million at June 30, 2025. Changes in our cash position from December 31, 2024 to June 30, 2025 are described in further detail below. Operating Activities - Operating cash flows generally represent our net income as adjusted for certain non-cash items and changes in assets and liabilities. Net cash provided by operating activities for the six months ended June 30, 2025 was approximately $302.2 million compared to approximately $412.0 million for the six months ended June 30, 2024. The decrease in our operating cash flow period-over-period was a result of an increase in working capital, primarily on our construction projects, given the progression on a number of contracts for which we were previously billed ahead. As we worked through these upfront payments, we saw the expected decrease in operating cash as our cash outflows exceeded our inflows on these projects. Such decrease was partially offset by an increase in our net income for the six months ended June 30, 2025 compared to the six months ended June 30, 2024. Investing Activities - Investing cash flows consist primarily of payments for acquisition of businesses, capital expenditures, and proceeds from the sale or disposal of property, plant, and equipment. Net cash used in investing activities for the six months ended June 30, 2025 increased by approximately $727.7 million compared to the six months ended June 30, 2024, predominantly due to the acquisition of Miller Electric. Financing Activities - Financing cash flows consist primarily of the issuance and repayment of short-term and long-term debt, repurchases of common stock, payments of dividends to stockholders, and the issuance of common stock through certain equity plans. Net cash used in financing activities was $231.1 million for the six months ended June 30, 2025 compared to $181.4 million for the six months ended June 30, 2024. The $49.7 million variance was primarily due to a $283.2 million increase in common stock repurchases made by us, partially offset by $250.0 million in net borrowings made under our revolving credit facility during the first half of 2025. The timing of common stock repurchases is at management's discretion subject to securities laws and other legal requirements and depends upon several factors, including market and business conditions, current and anticipated future liquidity, share price, and share availability, among others. For additional detail regarding our share repurchase program, refer to Note 10 - Common Stock of the notes to consolidated financial statements. 39 We currently pay a regular quarterly dividend of $0.25 per share. For the six months ended June 30, 2025 and 2024, cash payments related to dividends were $22.6 million and $20.2 million, respectively. Our credit agreement places limitations on the payment of dividends on our common stock. However, we do not believe that the terms of such agreement currently materially limit our ability to pay such quarterly dividends for the foreseeable future. Effect of Exchange Rate Changes on Cash, Cash Equivalents, and Restricted Cash - We are exposed to fluctuations in foreign currency exchange rates, almost entirely with respect to the British pound. Therefore, the $15.5 million variance between the six months ended June 30, 2025 and 2024 was a direct result of exchange rate movements for the British pound versus the United States dollar.

Material Cash Requirements from Contractual and Other Obligations As of June 30, 2025, our short-term and long-term material cash requirements for known contractual and other obligations were as follows: Outstanding Debt and Interest Payments - As of June 30, 2025, we had $250.0 million in direct borrowings outstanding under our revolving credit facility. Future interest payments will be determined based on prevailing interest rates at that time. Refer to Note 7 - Debt of the notes to consolidated financial statements for further detail of our debt obligations, including our revolving credit facility. Operating and Finance Leases - In the normal course of business, we lease real estate, vehicles, and equipment under various arrangements which are classified as either operating or finance leases. Future payments for such leases, excluding leases with initial terms of one year or less, were $499.3 million at June 30, 2025, with $112.1 million payable within the next 12 months. Open Purchase Obligations - As of June 30, 2025, we had $2.82 billion of open purchase obligations, of which payments totaling approximately $2.39 billion are expected to become due within the next 12 months. These obligations represent open purchase orders to suppliers and subcontractors related to our construction and services contracts. These purchase orders are not reflected in the Consolidated Balance Sheets and are not expected to impact future liquidity as amounts should be recovered through customer billings. Insurance Obligations - As described in further detail in Note 12 - Commitments and Contingencies of the notes to consolidated financial statements, we have loss payment deductibles and/or self-insured retentions for certain insurance matters. As of June 30, 2025, our insurance liabilities, net of estimated recoveries, were $262.1 million. Of this net amount, approximately $56.6 million is estimated to be payable within the next 12 months. Due to many uncertainties inherent in resolving these matters, it is not practical to estimate these payments beyond such period. To the extent that the amount required to settle claims covered by insurance continues to increase, the cost of our insurance coverage, including premiums and deductibles, is likely to increase. Contingent Consideration Liabilities - We have incurred liabilities related to contingent consideration arrangements associated with certain acquisitions, payable in the event discrete performance objectives are achieved by the acquired businesses during designated post-acquisition periods. The aggregate amount of these liabilities can change due to additional business acquisitions, settlement of outstanding liabilities, changes in the fair value of amounts owed based on performance during such post-acquisition periods, and accretion in present value. As of June 30, 2025, the present value of expected future payments relating to these contingent consideration arrangements was $15.0 million. Of this amount, $13.5 million is estimated as being payable within the next 12 months, with the remainder due pursuant to the terms of our contractual agreements, some of which extend into 2027.

$302,160 $247,572 Diluted earnings per common share$6.72 $5.25 Revenues of $4.30 billion for the quarter ended June 30, 2025 set a new quarterly record for the Company and represent an increase of 17.4% from revenues of $3.67 billion for the quarter ended June 30, 2024. Demand for our services continues to be strong across most of the market sectors we serve and, as described in further detail below, we experienced revenue growth within all of our reportable segments, except for our United States industrial services segment. Revenues for the second quarter of 2025 included incremental acquisition contribution of approximately $330.3 million. Operating income for the quarter ended June 30, 2025 was $415.2 million, establishing a new quarterly record for the Company, and operating margin was 9.6%, a record for the Company with respect to a second quarter. This compares to operating income of $332.8 million, or 9.1% of revenues, for the quarter ended June 30, 2024. The $82.4 million increase in operating income, and corresponding 50 basis point expansion in operating margin, were predominantly a result of improved operating performance within our United States construction segments, as described in further detail below. Operating income for the quarter ended June 30, 2025 included incremental acquisition contribution of $9.2 million, net of amortization expense attributable to identifiable intangible assets of $12.5 million. Net income of $302.2 million, or $6.72 per diluted share, for the quarter ended June 30, 2025 compares favorably to net income of $247.6 million, or $5.25 per diluted share, for the quarter ended June 30, 2024. While the majority of the increase in our net income and diluted earnings per share was a result of the increased operating income referenced above, diluted earnings per share for the quarter ended June 30, 2025 additionally benefited from a reduced weighted average share count given the impact of common stock repurchases made by us throughout 2024 and the first half of 2025.
