Management Discussion synthesis.

•United States building services; and •United States industrial services. We refer to our United States electrical construction and facilities services segment and our United States mechanical construction and facilities services segment together as our United States construction segments. On December 1, 2025, we sold our United Kingdom operations, the results of which are reported within our United Kingdom building services segment through the date of sale.

20252024 Selling, general and administrative expenses$1,714,446 $1,420,188 SG&A margin10.1 %9.7 % Our selling, general and administrative expenses for the year ended December 31, 2025 were $1.71 billion, or 10.1% of revenues, compared to selling, general and administrative expenses of $1.42 billion, or 9.7% of revenues, for the year ended December 31, 2024. Selling, general and administrative expenses for 2025 included $141.3 million of incremental expenses directly related to companies acquired, including amortization expense attributable to identifiable intangible assets of $22.5 million. Additionally included in selling, general and administrative expenses for 2025 were $9.4 million of transaction related costs incurred in connection with the acquisition of Miller Electric and $10.7 million of transaction related costs incurred in connection with the sale of our United Kingdom operations. 25 Excluding incremental expenses resulting from acquisitions and dispositions, our selling, general and administrative expenses increased by $132.9 million, primarily as a result of greater: (a) incentive compensation expense, predominantly within our United States construction segments, given higher 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 40 basis point increase in our SG&A margin for the year ended December 31, 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, and (b) the impact of the transaction related costs referenced above.

Total impact$24,557 $16,464 There were no significant amounts of revenue recognized during the year ended December 31, 2022 related to performance obligations satisfied in prior periods. 32 Included in our results for the year ended December 31, 2024 was $12.3 million of gross profit recognized on two contracts, which are currently in process, as a result of favorable developments on certain claims. Of this amount, $8.4 million was reported within our United States electrical construction and facilities services segment and $3.9 million was reported within our United States mechanical construction and facilities services segment. Based on an evaluation of individual projects that had revisions to total estimated costs or anticipated contract value that resulted in a reduction of profitability in excess of $1.0 million, our operating results were negatively impacted during the years ended December 31, 2024, 2023, and 2022, as summarized in the following table (in thousands):

Liquidity and Capital Resources The following section discusses our principal liquidity and capital resources, as well as our primary liquidity requirements and sources and uses of cash. We are focused on the efficient conversion of operating income into cash to provide for the Company's material cash requirements, including working capital needs, investment in our growth strategies through business acquisitions and capital expenditures, satisfaction of contractual commitments, including principal and interest payments on any outstanding indebtedness, and shareholder return through share repurchases and dividend payments. We strive to maintain a balanced approach to capital allocation in order to achieve growth, deliver value, and minimize risk. Management monitors financial markets and overall economic conditions for factors that may affect our liquidity and capital resources and adjusts our capital allocation strategy as necessary. Negative macroeconomic trends could have an adverse effect on future liquidity if we experience delays in the payment of outstanding receivables beyond normal payment terms, an increase in credit losses, or significant increases in the price of commodities or the materials and equipment utilized for our project and service work, beyond those experienced in recent years. In addition, during economic downturns, there have typically been fewer small discretionary projects from the private sector and our competitors have aggressively bid larger long-term infrastructure and public sector contracts. Our liquidity is also impacted by: (a) the type and length of construction contracts in place, as performance of long duration contracts typically requires greater amounts of working capital, (b) the level of turnaround activities within our United States industrial services segment, as such projects are billed in arrears pursuant to contractual terms that are standard within the industry, and (c) the billing terms of our maintenance contracts, including those within our United States building services segment. While we strive to negotiate favorable billing terms, which allow us to invoice in advance of costs incurred on certain of our contracts, there can be no assurance that such terms will be agreed to by our customers. As of December 31, 2025, we had cash and cash equivalents of $1.11 billion, which are maintained in depository accounts and highly liquid investments with original maturity dates of three months or less. Both our short-term and long-term liquidity requirements are expected to be met through our cash and cash equivalent balances, cash generated from our operations, and, as necessary, the borrowing capacity under our revolving credit facility. Our credit agreement provides for a $1.30 billion revolving credit facility, for which there was $1.23 billion of available capacity as of December 31, 2025. Refer to Note 9 - Debt of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data for further information regarding our credit agreement. Based upon our current credit rating and financial position, we can also reasonably expect to be able to secure long-term debt financing if required to achieve our strategic objectives; however, no assurances can be made that such debt financing will be available on favorable terms. We believe that we have sufficient financial resources available to meet our short-term and foreseeable long-term liquidity requirements.

Cash Flows The following table presents a summary of our operating, investing, and financing cash flows (in thousands): 20252024 Net cash provided by operating activities$1,302,063 $1,407,894

Net cash used in investing activities$(873,586)$(299,284) Net cash used in financing activities$(663,761)$(555,365) Effect of exchange rate changes on cash, cash equivalents, and restricted cash$6,857 $(2,600)

(Decrease) increase in cash, cash equivalents, and restricted cash $(228,427)$550,645 During the year ended December 31, 2025, our cash balance, including cash equivalents and restricted cash, decreased by $228.4 million from $1.34 billion at December 31, 2024 to $1.11 billion at December 31, 2025. Changes in our cash position from December 31, 2024 to December 31, 2025 are described in further detail below. For a discussion of the changes in our cash position from December 31, 2023 to December 31, 2024, refer to the Liquidity and Capital Resources section included in Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations of our Form 10-K for the year ended December 31, 2024. Operating Activities - Operating cash flows generally represent our net income as adjusted for certain non-cash items and changes in assets and liabilities. For 2025, net cash provided by operating activities was approximately $1.30 billion compared to approximately $1.41 billion in 2024. The $105.8 million decrease in our operating cash flow 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 a year-over-year increase in our net income. 29 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 or other long-term assets. Net cash used in investing activities for 2025 increased by approximately $574.3 million compared to 2024, primarily due to an increase in payments for acquisitions, including Miller Electric, partially offset by the proceeds from the sale of our United Kingdom operations. 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 during 2025 was $663.8 million compared to $555.4 million during 2024. The $108.4 million variance was primarily due to an increase in common stock repurchases made by us. 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 12 - Common Stock of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data. During 2025, we paid a regular quarterly dividend of $0.25 per share. For the years ended December 31, 2025 and 2024, cash payments related to dividends were $45.0 million and $43.4 million, respectively. In December 2025, our Board of Directors announced its intention to increase the regular quarterly dividend to $0.40 per share commencing with the dividend to be paid in January 2026. 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 - Prior to the sale of our United Kingdom operations in December of 2025, we were exposed to fluctuations in foreign currency exchange rates with respect to the British pound. Therefore, the $9.5 million variance between the years ended December 31, 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 December 31, 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 December 31, 2025, there were no direct borrowings outstanding under our revolving credit facility. Interest payments on any future borrowings will be determined based on prevailing interest rates at that time. Refer to Note 9 - Debt of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data 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 $570.5 million at December 31, 2025, with $122.3 million payable within the next 12 months. Refer to Note 16 - Leases of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data for further detail surrounding our lease obligations and the timing of expected future payments. Open Purchase Obligations - As of December 31, 2025, we had $3.07 billion of open purchase obligations, of which payments totaling approximately $2.63 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 2 - Summary of Significant Accounting Policies of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data, we have loss payment deductibles and/or self-insured retentions for certain insurance matters. As of December 31, 2025, our insurance liabilities, net of estimated recoveries, were $291.0 million. Of this net amount, approximately $68.5 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 December 31, 2025, the present value of expected future payments relating to these contingent consideration arrangements was $8.8 million. Of this amount, $7.3 million is estimated as being payable during 2026. 30

United States building services- - 5,658 Total impact$85,941 $66,319 $29,057 Due to the significant judgments utilized in the estimation process described above, if subsequent actual results and/or updated assumptions, estimates, or projections related to our underlying project positions were to change from those utilized at December 31, 2025, it could result in a material impact to our results of operations. For example, a 50 basis point increase or decrease in the estimated gross profit margin on our uncompleted construction projects, in the aggregate, as a result of a revision in estimated costs to complete a performance obligation or a revision in estimated transaction price, would have resulted in an increase or decrease to operating income of approximately $175 million for the year ended December 31, 2025. See Note 3 - Revenue from Contracts with Customers of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data for further disclosure regarding revenue recognition.

Insurance Liabilities We have loss payment deductibles for certain workers' compensation, automobile liability, general liability, and property claims, have self-insured retentions for certain other casualty claims, and are self-insured for employee-related healthcare claims. In addition, we maintain a wholly-owned captive insurance subsidiary to manage certain of our insurance liabilities. Losses are recorded based upon estimates of our liability for claims incurred and for claims incurred but not reported. The liabilities are derived from known facts, historical trends, and industry averages, utilizing the assistance of an independent third-party actuary to determine the best estimate for the majority of these obligations. We believe the liabilities recognized on the Consolidated Balance Sheets for these obligations are adequate. However, such obligations are difficult to assess and estimate due to numerous factors, including severity of injury, determination of liability in proportion to other parties, timely reporting of occurrences, and effectiveness of safety and risk management programs. Therefore, if our actual experience differs from the assumptions and estimates used for recording the liabilities, adjustments may be required and will be recorded in the period that the experience becomes known. In addition, an increase in the cost to settle insurance claims could result in higher insurance costs and deductibles. As of December 31, 2025, our estimated net insurance liabilities for workers' compensation, automobile liability, general liability, and property claims increased by $50.8 million when compared to December 31, 2024. Such increase was a result of greater potential exposures, including the impact of acquired companies, and an increase in certain of our deductibles or self-insured retentions. If our estimated insurance liabilities for workers' compensation, automobile liability, general liability, and property claims were to increase by 10%, it would have resulted in $29.1 million of additional expense for the year ended December 31, 2025.

Due to the inherent uncertainties involved in making estimates, our assumptions may change in future periods. Estimates and assumptions made for purposes of our goodwill impairment testing may prove to be inaccurate predictions of the future, and other factors used in assessing fair value, such as the weighted average cost of capital, are outside the control of management. Unfavorable changes in certain of these key assumptions may affect future testing results. For example, keeping all other assumptions constant, a 50 basis point increase in the weighted average cost of capital would cause the estimated fair values of our United States electrical construction and facilities services segment, our United States mechanical construction and facilities services segment, our United States building services segment, and our United States industrial services segment to decrease by approximately $445.2 million, $609.5 million, $99.5 million, and $25.3 million, respectively. In addition, keeping all other assumptions constant, a 50 basis point reduction in the perpetual growth rate would cause the estimated fair values of our United States electrical construction and facilities services segment, our United States mechanical construction and facilities services segment, our United States building services segment, and our United States industrial services segment to decrease by approximately $242.3 million, $342.4 million, $49.2 million, and $9.9 million, respectively. Given the amounts by which the fair value exceeds the carrying value for each of our reporting units, the decreases in estimated fair values described above would not have significantly impacted the results of our 2025 impairment tests. Further, for each of our reporting units, a 10% decline in the estimated fair value of such reporting unit, due to other changes in our assumptions, including forecasted future cash flows, would not have significantly impacted the results of our 2025 impairment tests.

Goodwill, Identifiable Intangible Assets, and Other Long-Lived Assets Goodwill As of December 31, 2025 and 2024, we had goodwill of $1.41 billion and $1.02 billion, respectively, arising out of the acquisition of businesses. Goodwill is not amortized but instead allocated to its respective reporting unit and evaluated for impairment annually, or more frequently if events or circumstances indicate that the carrying amount of goodwill may be impaired. We have determined that our reporting units are consistent with the reportable segments identified in Note 18 - Segment Information of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data. As of December 31, 2025, approximately 36.7% of our goodwill related to our United States electrical construction and facilities services segment, approximately 28.5% related to our United States mechanical construction and facilities services segment, approximately 26.0% related to our United States building services segment, and approximately 8.8% related to our United States industrial services segment. 33 Absent any earlier identified impairment indicators, we perform our annual goodwill impairment assessment on October 1 each fiscal year. Qualitative indicators that may trigger the need for interim quantitative impairment testing include, among others, a deterioration in macroeconomic conditions, declining financial performance, deterioration in the operational environment, or an expectation of selling or disposing of a portion of a reporting unit. Additionally, an interim impairment test may be triggered by a significant change in business climate, a loss of a significant customer, increased competition, or a sustained decrease in share price. In assessing whether our goodwill is impaired, we compare the fair value of the reporting unit to its carrying amount, including goodwill. If the fair value exceeds the carrying amount, no impairment is recognized. However, if the carrying amount of the reporting unit exceeds the fair value, the goodwill of the reporting unit is impaired and an impairment loss in the amount of the excess is recognized and charged to operations. We performed our annual impairment assessment of all reporting units as of October 1, 2025 and determined there was no impairment of goodwill. Based on these impairment assessments, the fair values of our United States electrical construction and facilities services segment, our United States mechanical construction and facilities services segment, our United States building services segment, and our United States industrial services segment exceeded their carrying values by approximately $6.43 billion, $10.11 billion, $1.27 billion, and $120.3 million, respectively. As part of such annual testing, we compared the aggregate fair value of our reporting units to our market capitalization, noting that such comparison supported the reasonableness of the key assumptions utilized in determining the fair value of each of our reporting units. In completing our annual impairment assessment, we determined the fair value of each of our reporting units using an income approach whereby fair value was calculated utilizing discounted estimated future cash flows, assuming a risk-adjusted industry weighted average cost of capital. The weighted average cost of capital used in our annual impairment testing was 10.4% for our United States construction segments, 11.0% for our United States building services segment, and 10.6% for our United States industrial services segment. These weighted average cost of capital estimates were developed with the assistance of an independent third-party valuation specialist and reflect the overall level of inherent risk within the respective reporting unit and the rate of return a market participant would expect to earn. Our cash flow projections were derived from our most recent internal forecasts of anticipated revenue growth rates and operating margins, with cash flows beyond the discrete forecast period estimated using a terminal value calculation which incorporated historical and forecasted trends, an estimate of long-term growth rates, and assumptions about the future demand for our services. The perpetual growth rate used for our annual testing was 2.5% for all of our reporting units.

Identifiable Intangible Assets and Other Long-Lived Assets As of December 31, 2025 and 2024, net identifiable intangible assets (primarily consisting of our customer relationships, subsidiary trade names, contract backlog, and developed technology/vendor network) arising out of the acquisition of businesses were $1.11 billion and $648.2 million, respectively. The determination of identifiable intangible asset values, related estimated useful lives, and whether those assets are impaired involves significant judgments based upon short- and long-term projections of future performance. These forecasts reflect assumptions regarding anticipated macroeconomic conditions as well as our ability to successfully integrate acquired businesses. Absent earlier indicators of impairment, we test for impairment of subsidiary trade names that are not subject to amortization on an annual basis (October 1). In addition, we review for impairment of identifiable intangible assets that are being amortized as well as other long-lived assets whenever facts and circumstances indicate that their carrying values may not be fully recoverable. 34 As of October 1, 2025, we performed our annual impairment testing of all subsidiary trade names that are not subject to amortization and determined that there was no impairment of these assets. In performing this impairment assessment, we considered the sensitivity of the reported amounts to the methods, assumptions, and estimates underlying our testing. For example, we performed sensitivity analyses and concluded that, individually, none of the following changes in estimates or assumptions would have significantly impacted the results of our testing or resulted in a material impairment of our subsidiary trade names: (a) a 50 basis point increase in the discount rate utilized in our testing, (b) a 50 basis point decline in the perpetual growth rate utilized in our testing, or (c) a 10% decrease in the estimated fair value of each trade name. With respect to identifiable intangible assets that are being amortized as well as other long-lived assets, we did not identify any circumstances indicating that their carrying values may not be fully recoverable and, therefore, no impairment testing was required for these assets during the year ended December 31, 2025. During 2023, we identified facts and circumstances that indicated the carrying values of certain long-lived assets within our United States mechanical construction and facilities services segment may not be fully recoverable, necessitating a comparison of their carrying values to the undiscounted pre-tax cash flows estimated to result from the use of such assets. As a result of this test, we determined that these assets were impaired, and recognized a $2.4 million impairment charge as calculated using a discounted cash flow model.

Discussion and Analysis of Results of Operations Revenues The following table presents our revenues for each of our operating segments and the approximate percentages that each segment's revenues were of total revenues for the years ended December 31, 2025 and 2024 (in thousands, except for percentages):

2025% of Total 2024% of Total Revenues from unrelated entities: United States electrical construction and facilities services$5,074,252 30 %$3,342,927 23 %

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. The amounts discussed 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 included in Item 8. Financial Statements and Supplementary Data. During 2024, we acquired seven companies 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. During 2023, we acquired eight companies for total consideration of $99.6 million. Such acquisitions include: (a) a national energy efficiency specialty services firm, the results of operations of which have been included in our United States building services segment, and (b) seven companies, the results of operations of which were de minimis, consisting of: (i) three companies that have been included within our United States mechanical construction and facilities services segment, one of which provides mechanical and pipe fabrication services in the Midwestern region of the United States, and two of which add capabilities to our national fire protection services, and (ii) four mechanical services companies in the Western and Midwestern regions of the United States that have been included within our United States building services segment and enhance our presence in geographies where we have existing operations. During 2022, we acquired six companies for total consideration of $100.8 million. Such acquisitions include: (a) a company that provides electrical construction services in the Greater Boston area, the results of operations of which have been included in our United States electrical construction and facilities services segment, and (b) five companies that enhance our presence in geographies where we have existing operations, the results of operations of which were de minimis, consisting of: (i) two companies that provide fire protection services in the Northeastern and Southern regions of the United States, respectively, and that have been included within our United States mechanical construction and facilities services segment, (ii) two companies that specialize in either building automation and controls or mechanical services in the Southwestern and Southern regions of the United States, respectively, and that have been included within our United States building services segment, and (iii) a company that provides electrical construction services in the Midwestern region of the United States and that has been included within our United States electrical construction and facilities services segment.

Refer to the operating income section below for further discussion regarding the operating performance of each of our reportable segments. Selling, general and administrative expenses The following table presents selling, general and administrative expenses ("SG&A") and selling, general and administrative expenses as a percentage of revenues ("SG&A margin") for the years ended December 31, 2023 and 2022 (in thousands, except for percentages):

20232022 Selling, general and administrative expenses$1,211,233 $1,038,717 SG&A margin9.6 %9.4 % Our selling, general and administrative expenses for the year ended December 31, 2023 were $1,211.2 million, or 9.6% of revenues, compared to selling, general and administrative expenses of $1,038.7 million, or 9.4% of revenues, for the year ended December 31, 2022. For the year ended December 31, 2023, selling, general and administrative expenses included $17.3 million of incremental expenses directly related to companies acquired in 2023 and 2022, including amortization expense attributable to identifiable intangible assets of $4.6 million. Excluding incremental expenses from businesses acquired, the increase in selling, general and administrative expenses, and SG&A margin, was predominantly attributable to increases in incentive compensation expense across the majority of our reportable segments, due to higher operating results than in the prior year, and salaries and related employment expenses, largely as a result of additional headcount to support our organic revenue growth as well as annual cost of living adjustments. In addition to these increases in employment costs, our SG&A for 2023 included incremental: (a) computer hardware and software costs, as a result of various information technology and cybersecurity initiatives currently in process, (b) travel and entertainment expenses, and (c) rent and other occupancy costs driven by: (i) the expansion or addition of certain fabrication facilities, which support our operations, and (ii) the impact of inflation on the real estate market. 26

Increase (decrease) in cash, cash equivalents, and restricted cash $332,682 $(365,500) During the year ended December 31, 2023, our cash balance, including cash equivalents and restricted cash, increased by $332.7 million from $457.1 million at December 31, 2022 to $789.8 million at December 31, 2023. Changes in our cash position from December 31, 2022 to December 31, 2023 are described in further detail below. For a discussion of the changes in our cash position from December 31, 2021 to December 31, 2022, refer to the Liquidity and Capital Resources section included in Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations of our Form 10-K for the year ended December 31, 2022. Operating Activities - Operating cash flows generally represent our net income as adjusted for certain non-cash items and changes in assets and liabilities. For 2023, net cash provided by operating activities was approximately $899.7 million compared to approximately $497.9 million of net cash provided by operating activities in 2022. The $401.7 million increase in operating cash flows during 2023, when compared to 2022, was largely a result of increased income, coupled with customer deposits and advanced payments on certain construction contracts, as evidenced by the growth in our contract liabilities. 30 Investing Activities - Investing cash flows consist primarily of payments for the acquisition of businesses, capital expenditures, and proceeds from the sale or disposal of property, plant, and equipment. During 2023, we utilized approximately $161.3 million of cash for investing activities compared to $140.8 million during 2022. The increase in investing cash outflows year-over-year was primarily driven by higher capital expenditures to support our organic growth, partially offset by an increase in proceeds from the sale or disposal of property, plant, and equipment. Payments for the acquisition of businesses were fairly consistent each year as we utilized $96.5 million in 2023, compared to $98.7 million in 2022. 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 during 2023 was $412.1 million compared to $710.1 million during 2022. The $298.1 million reduction in financing cash outflows was primarily due to a decrease in funds used for the repurchase of our common stock during 2023, partially offset by an increase in net repayments of debt under our credit agreement. 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 12 - Common Stock of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data. We currently pay a regular quarterly dividend of $0.18 per share. For the years ended December 31, 2023 and 2022, cash payments related to dividends were $32.7 million and $27.2 million, respectively. Subsequent to December 31, 2023, our Board of Directors announced its intention to increase the regular quarterly dividend to $0.25 per share commencing with the dividend to be paid in April 2024. 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 $18.9 million variance between the years ended December 31, 2023 and 2022 was a direct result of favorable exchange rate movements for the British pound versus the United States dollar.

10,864 13,679 2,264 United States building services 5,658 1,261 - Total impact $29,057 $48,403 $6,891 During the year ended December 31, 2023, we recognized revenue of approximately $16.5 million on individual projects that were substantially complete in prior periods but had revisions to total estimated cost or anticipated contract value, which resulted in an increase to profitability in excess of $1.0 million. Of this amount, approximately $3.4 million was reported within our United States electrical construction and facilities services segment and approximately $13.1 million was reported within our United States mechanical construction and facilities services segment. There were no significant amounts of revenue recognized during the years ended December 31, 2022 or 2021 related to performance obligations satisfied in prior periods. Due to the significant judgments utilized in the estimation process described above, if subsequent actual results and/or updated assumptions, estimates, or projections related to our underlying project positions were to change from those utilized at December 31, 2023, it could result in a material impact to our results of operations. For example, a 50 basis point increase or decrease in the estimated gross profit margin on our uncompleted construction projects, in the aggregate, as a result of a revision in estimated costs to complete a performance obligation or a revision in estimated transaction price, would have resulted in an increase or decrease to operating income of approximately $100 million for the year ended December 31, 2023. See Note 3 - Revenue from Contracts with Customers of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data for further disclosure regarding revenue recognition.

Other Considerations As referenced above, impairment testing is based upon assumptions and estimates determined by management from a review of our operating results and business plans as well as forecasts of anticipated growth rates and margins, among other considerations. In addition, estimates of weighted average costs of capital are developed with the assistance of an independent third-party valuation specialist. These assumptions and estimates may change in future periods, especially in times of uncertain economic conditions and rising interest rates. Significant adverse changes to external market conditions or our internal forecasts, if any, could result in future impairment charges, particularly with respect to our United States industrial services segment given that the fair value of this reporting unit more closely approximates its carrying value. It is not possible at this time to determine if any future impairment charge will result or, if it does, whether such a charge would be material to our results of operations. Refer to Note 8 - Goodwill, Identifiable Intangible Assets, and Other Long-Lived Assets of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data for further information about our goodwill and identifiable intangible assets as well as our impairment testing. No impairment of our goodwill, identifiable intangible assets, or other long-lived assets was recognized during the years ended December 31, 2022 or 2021.

Other items Interest expense was $3.8 million and $17.2 million for the years ended December 31, 2024 and 2023, respectively. The year-over-year decrease in interest expense was a result of the repayment, in December of 2023, of all previously outstanding direct borrowings under our credit facility. Interest income was $35.4 million and $15.4 million for the years ended December 31, 2024 and 2023, respectively. The increase in annual interest income resulted from greater returns on our invested cash, due to an increase in our average daily invested cash balance. Our income tax provision for the year ended December 31, 2024 was $370.2 million, based on an income tax rate of 26.9%, compared to an income tax provision and an income tax rate of $239.5 million and 27.5%, respectively, for the year ended December 31, 2023.

Material Cash Requirements from Contractual and Other Obligations As of December 31, 2024, 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 December 31, 2024, there were no direct borrowings outstanding under our revolving credit facility. Interest payments on any future borrowings will be determined based on prevailing interest rates at that time. Refer to Note 9 - Debt of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data 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 $390.1 million at December 31, 2024, with $96.9 million payable within the next 12 months. Refer to Note 16 - Leases of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data for further detail surrounding our lease obligations and the timing of expected future payments. Open Purchase Obligations - As of December 31, 2024, we had $2.33 billion of open purchase obligations, of which payments totaling approximately $2.01 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 2 - Summary of Significant Accounting Policies of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data, we have loss payment deductibles and/or self-insured retentions for certain insurance matters. As of December 31, 2024, our insurance liabilities, net of estimated recoveries, were $240.1 million. Of this net amount, approximately $41.6 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 December 31, 2024, the present value of expected future payments relating to these contingent consideration arrangements was $29.7 million. Of this amount, $20.4 million is estimated as being payable during 2025, with the remainder due pursuant to the terms of our contractual agreements, some of which extend into 2027. 30

In addition, material cash requirements for other potential obligations, for which we cannot reasonably estimate future payments, include the following: Legal Proceedings - We are involved in several legal proceedings in which damages and claims have been asserted against us. While litigation is subject to many uncertainties and the outcome of litigation is not predictable with assurance, we do not believe that any such matters will have a material adverse effect on our financial position, results of operations, or liquidity. Refer to Note 15 - Commitments and Contingencies of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data for more information regarding legal proceedings. Multiemployer Benefit Plans - In addition to our Company sponsored benefit plans, we participate in certain multiemployer pension and other post-retirement plans. The cost of these plans is equal to the annual required contributions determined in accordance with the provisions of negotiated collective bargaining agreements. During 2024, 2023, and 2022, contributions made to these plans were $577.0 million, $502.3 million, and $449.9 million, respectively; however, our future contributions to the multiemployer plans are dependent upon a number of factors. Amounts of future contributions that we would be contractually obligated to make pursuant to these plans cannot be reasonably estimated. Refer to Note 14 - Retirement Plans of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data for more information regarding multiemployer benefit plans.

We do not have any other material financial guarantees or off-balance sheet arrangements other than those disclosed herein. 31 Other Items To help mitigate the impacts of greenhouse gas emissions on climate change, EMCOR has established initial carbon-based fuel consumption and greenhouse gas emission reduction targets. Although to date we have not incurred any material costs or capital expenditures associated with achieving our targets, we could be required to expend amounts in future periods as we continue to work towards our goals. It is not possible, at this time, to estimate the impact that future costs and/or capital expenditures may have on our business, financial condition, results of operations, or liquidity.

Revenue Recognition from Contracts with Customers The Company recognizes revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services by applying the following five step model: (1) identify the contract with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; (5) recognize revenue as performance obligations are satisfied. The nature of our contracts gives rise to several types of variable consideration, including pending change orders and claims; contract bonuses and incentive fees; and liquidated damages and penalties. We recognize revenue for such variable consideration when it is probable, in our judgment, that a significant future reversal in the amount of cumulative revenue recognized under the contract will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The Company estimates the amount of variable consideration to be included in the transaction price utilizing one of two prescribed methods, depending on which method better predicts the amount of consideration to which the entity will be entitled. Due to uncertainties inherent in the estimation process, as well as the significant judgment involved in determining variable consideration, it is possible that estimates of costs to complete a performance obligation, and/or our estimates of transaction prices, will be revised in the near term. For those performance obligations for which revenue is recognized using a cost-to-cost input method, changes in total estimated costs, and related progress towards complete satisfaction of the performance obligation, or changes in the estimate of transaction prices, are recognized on a cumulative catch-up basis in the period in which the revisions to the estimates are made. Based on an evaluation of individual projects that were substantially complete in prior periods but had revisions to total estimated costs or anticipated contract value (inclusive of the settlement of previously outstanding change orders and claims) that resulted in an increase to profitability in excess of $1.0 million, we recognized revenue during the years ended December 31, 2024 and 2023, as summarized in the following table (in thousands):

Operating income$1,344,863 $875,756 Operating income as a percentage of revenues9.2 %7.0 % Net income attributable to EMCOR Group, Inc.$1,007,145 $632,994

Due to the inherent uncertainties involved in making estimates, our assumptions may change in future periods. Estimates and assumptions made for purposes of our goodwill impairment testing may prove to be inaccurate predictions of the future, and other factors used in assessing fair value, such as the weighted average cost of capital, are outside the control of management. Unfavorable changes in certain of these key assumptions may affect future testing results. For example, keeping all other assumptions constant, a 50 basis point increase in the weighted average cost of capital would cause the estimated fair values of our United States electrical construction and facilities services segment, our United States mechanical construction and facilities services segment, our United States building services segment, and our United States industrial services segment to decrease by approximately $226.5 million, $383.7 million, $93.5 million, and $32.5 million, respectively. In addition, keeping all other assumptions constant, a 50 basis point reduction in the perpetual growth rate would cause the estimated fair values of our United States electrical construction and facilities services segment, our United States mechanical construction and facilities services segment, our United States building services segment, and our United States industrial services segment to decrease by approximately $123.2 million, $210.1 million, $46.0 million, and $13.0 million, respectively. Given the amounts by which the fair value exceeds the carrying value for each of our reporting units, the decreases in estimated fair values described above would not have significantly impacted the results of our 2024 impairment tests. Further, for each of our reporting units, a 10% decline in the estimated fair value of such reporting unit, due to other changes in our assumptions, including forecasted future cash flows, would not have significantly impacted the results of our 2024 impairment tests.

Goodwill, Identifiable Intangible Assets, and Other Long-Lived Assets Goodwill As of December 31, 2024 and 2023, we had goodwill of $1,018.4 million and $956.5 million, respectively, arising out of the acquisition of businesses. Goodwill is not amortized but instead allocated to its respective reporting unit and evaluated for impairment annually, or more frequently if events or circumstances indicate that the carrying amount of goodwill may be impaired. We have determined that our reporting units are consistent with the reportable segments identified in Note 18 - Segment Information of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data. As of December 31, 2024, approximately 18.8% of our goodwill related to our United States electrical construction and facilities services segment, approximately 33.8% related to our United States mechanical construction and facilities services segment, approximately 35.2% related to our United States building services segment, and approximately 12.2% related to our United States industrial services segment. 33 Absent any earlier identified impairment indicators, we perform our annual goodwill impairment assessment on October 1 each fiscal year. Qualitative indicators that may trigger the need for interim quantitative impairment testing include, among others, a deterioration in macroeconomic conditions, declining financial performance, deterioration in the operational environment, or an expectation of selling or disposing of a portion of a reporting unit. Additionally, an interim impairment test may be triggered by a significant change in business climate, a loss of a significant customer, increased competition, or a sustained decrease in share price. In assessing whether our goodwill is impaired, we compare the fair value of the reporting unit to its carrying amount, including goodwill. If the fair value exceeds the carrying amount, no impairment is recognized. However, if the carrying amount of the reporting unit exceeds the fair value, the goodwill of the reporting unit is impaired and an impairment loss in the amount of the excess is recognized and charged to operations. We performed our annual impairment assessment of all reporting units as of October 1, 2024 and determined there was no impairment of goodwill. Based on these impairment assessments, the fair values of our United States electrical construction and facilities services segment, our United States mechanical construction and facilities services segment, our United States building services segment, and our United States industrial services segment exceeded their carrying values by approximately $3,940.5 million, $6,852.3 million, $1,143.8 million, and $163.1 million, respectively. As part of such annual testing, we compared the aggregate fair value of our reporting units to our market capitalization, noting that such comparison supported the reasonableness of the key assumptions utilized in determining the fair value of each of our reporting units. In completing our annual impairment assessment, we determined the fair value of each of our reporting units using an income approach whereby fair value was calculated utilizing discounted estimated future cash flows, assuming a risk-adjusted industry weighted average cost of capital. The weighted average cost of capital used in our annual impairment testing was 10.6% for our United States construction segments, 10.9% for our United States building services segment, and 10.5% for our United States industrial services segment. These weighted average cost of capital estimates were developed with the assistance of an independent third-party valuation specialist and reflect the overall level of inherent risk within the respective reporting unit and the rate of return a market participant would expect to earn. Our cash flow projections were derived from our most recent internal forecasts of anticipated revenue growth rates and operating margins, with cash flows beyond the discrete forecast period estimated using a terminal value calculation which incorporated historical and forecasted trends, an estimate of long-term growth rates, and assumptions about the future demand for our services. The perpetual growth rate used for our annual testing was 2.5% for all of our reporting units.

Identifiable Intangible Assets and Other Long-Lived Assets As of December 31, 2024 and 2023, net identifiable intangible assets (primarily consisting of our customer relationships, subsidiary trade names, developed technology/vendor network, and contract backlog) arising out of the acquisition of businesses were $648.2 million and $586.0 million, respectively. The determination of related estimated useful lives for identifiable intangible assets and whether those assets are impaired involves significant judgments based upon short- and long-term projections of future performance. These forecasts reflect assumptions regarding anticipated macroeconomic conditions as well as our ability to successfully integrate acquired businesses. Absent earlier indicators of impairment, we test for impairment of subsidiary trade names that are not subject to amortization on an annual basis (October 1). In addition, we review for impairment of identifiable intangible assets that are being amortized as well as other long-lived assets whenever facts and circumstances indicate that their carrying values may not be fully recoverable. 34 As of October 1, 2024, we performed our annual impairment testing of all subsidiary trade names that are not subject to amortization and determined that there was no impairment of these assets. In performing this impairment assessment, we considered the sensitivity of the reported amounts to the methods, assumptions, and estimates underlying our testing. For example, we performed sensitivity analyses and concluded that, individually, none of the following changes in estimates or assumptions would have significantly impacted the results of our testing or resulted in a material impairment of our subsidiary trade names: (a) a 50 basis point increase in the discount rate utilized in our testing, (b) a 50 basis point decline in the perpetual growth rate utilized in our testing, or (c) a 10% decrease in the estimated fair value of each trade name. With respect to identifiable intangible assets that are being amortized as well as other long-lived assets, we did not identify any circumstances indicating that their carrying values may not be fully recoverable and, therefore, no impairment testing was required for these assets during the year ended December 31, 2024. During 2023, we identified facts and circumstances that indicated the carrying values of certain long-lived assets within our United States mechanical construction and facilities services segment may not be fully recoverable, necessitating a comparison of their carrying values to the undiscounted pre-tax cash flows estimated to result from the use of such assets. As a result of this test, we determined that these assets were impaired, and recognized a $2.4 million impairment charge as calculated using a discounted cash flow model.

Discussion and Analysis of Results of Operations Revenues The following table presents our revenues for each of our operating segments and the approximate percentages that each segment's revenues were of total revenues for the years ended December 31, 2024 and 2023 (in thousands, except for percentages):

Selling, general and administrative expenses The following table presents selling, general and administrative expenses ("SG&A") and selling, general and administrative expenses as a percentage of revenues ("SG&A margin") for the years ended December 31, 2023 and 2022 (in thousands, except for percentages):

Identifiable Intangible Assets and Other Long-Lived Assets As of December 31, 2023 and 2022, net identifiable intangible assets (primarily consisting of our customer relationships, subsidiary trade names, developed technology/vendor network, and contract backlog) arising out of the acquisition of businesses were $586.0 million and $594.0 million, respectively. The determination of related estimated useful lives for identifiable intangible assets and whether those assets are impaired involves significant judgments based upon short- and long-term projections of future performance. These forecasts reflect assumptions regarding anticipated macroeconomic conditions as well as our ability to successfully integrate acquired businesses. Absent earlier indicators of impairment, we test for impairment of subsidiary trade names that are not subject to amortization on an annual basis (October 1). In addition, we review for impairment of identifiable intangible assets that are being amortized as well as other long-lived assets whenever facts and circumstances indicate that their carrying values may not be fully recoverable. 35 As of October 1, 2023, we performed our annual impairment testing of all subsidiary trade names that are not subject to amortization and determined that there was no impairment of these assets. In performing this impairment assessment, we considered the sensitivity of the reported amounts to the methods, assumptions, and estimates underlying our testing. For example, we performed sensitivity analyses and concluded that, individually, none of the following changes in estimates or assumptions would have significantly impacted the results of our testing or resulted in a material impairment of our subsidiary trade names: (a) a 50 basis point increase in the discount rate utilized in our testing, (b) a 50 basis point decline in the perpetual growth rate utilized in our testing, or (c) a 10% decrease in the estimated fair value of each trade name. During the quarter ended September 30, 2023, we identified facts and circumstances that indicated the carrying values of certain long-lived assets within our United States mechanical construction and facilities services segment may not be fully recoverable, necessitating a comparison of their carrying values to the undiscounted pre-tax cash flows estimated to result from the use of such assets. As a result of this test, we determined that these assets were impaired, and, during the third quarter of 2023, recognized a $2.4 million impairment charge as calculated using a discounted cash flow model. For the year ended December 31, 2023, there were no other indicators of impairment with respect to identifiable intangible assets that are being amortized as well as other long-lived assets.

For a more complete description of our operations, refer to Item 1. Business. Our reportable segments and related disclosures reflect certain reclassifications of prior year amounts from our United States mechanical construction and facilities services segment to our United States building services segment, and from our United States building services segment to our United States construction segments, due to changes in our internal reporting structure aimed at realigning our service offerings.

Material Cash Requirements from Contractual and Other Obligations As of December 31, 2022, 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 December 31, 2022, there were no direct borrowings outstanding under our revolving credit facility and the amount outstanding under our term loan was $242.8 million. We are required to make annual principal payments on our term loan of $13.9 million on December 31 of each year until maturity. All remaining unpaid amounts are due on March 2, 2025, when the credit agreement governing our term loan and revolving credit facility expires. Until such time, we are required to make periodic interest payments on our outstanding indebtedness. Future interest payments will be determined based on prevailing interest rates during that time, which are anticipated to increase in the near term. Refer to Note 9 - Debt of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data for further detail of our debt obligations, including our term loan and 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 $325.7 million at December 31, 2022, with $78.3 million payable within the next 12 months. Refer to Note 16 - Leases of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data for further detail surrounding our lease obligations and the timing of expected future payments. Open Purchase Obligations - As of December 31, 2022, we had $2.24 billion of open purchase obligations, of which payments totaling approximately $1.94 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 2 - Summary of Significant Accounting Policies of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data, we have loss payment deductibles and/or self-insured retentions for certain insurance matters. As of December 31, 2022, our insurance liabilities, net of estimated recoveries, were $201.5 million. Of this net amount, approximately $38.8 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. 31 Retirement Plan Obligations - As of December 31, 2022, expected future payments relating to our defined benefit post retirement plans were approximately $1.5 million per year. We provide funding to our post retirement plans based on at least the minimum funding required by applicable regulations. In determining the minimum funding required, we utilize current actuarial assumptions and exchange rates to forecast amounts that may be payable. In our judgment, minimum funding estimates cannot be reliably estimated beyond a five-year time horizon. Refer to Note 14 - Retirement Plans of the notes to consolidated financial statements in Item 8. Financial Statements and Supplementary Data for further information about our post retirement plans. 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 December 31, 2022, the present value of expected future payments relating to these contingent consideration arrangements was $16.9 million. Of this amount, $10.0 million is estimated as being payable during 2023, with the remainder due pursuant to the terms of our contractual agreements some of which extend through 2025.

Revenue Recognition from Contracts with Customers The Company recognizes revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services by applying the following five step model: (1) identify the contract with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; (5) recognize revenue as performance obligations are satisfied. The nature of our contracts gives rise to several types of variable consideration, including pending change orders and claims; contract bonuses and incentive fees; and liquidated damages and penalties. We recognize revenue for such variable consideration when it is probable, in our judgment, that a significant future reversal in the amount of cumulative revenue recognized under the contract will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The Company estimates the amount of variable consideration to be included in the transaction price utilizing one of two prescribed methods, depending on which method better predicts the amount of consideration to which the entity will be entitled. 33 Due to uncertainties inherent in the estimation process, as well as the significant judgment involved in determining variable consideration, it is possible that estimates of costs to complete a performance obligation, and/or our estimates of transaction prices, will be revised in the near term. For those performance obligations for which revenue is recognized using a cost-to-cost input method, changes in total estimated costs, and related progress towards complete satisfaction of the performance obligation, or changes in the estimate of transaction prices, are recognized on a cumulative catch-up basis in the period in which the revisions to the estimates are made. Based on an evaluation of individual projects that had revisions to total estimated costs or anticipated contract value, which resulted in a reduction of profitability in excess of $1.0 million, our operating results were negatively impacted by approximately $48.5 million during the year ended December 31, 2022. Of this amount, approximately $33.5 million was reported within our United States electrical construction and facilities services segment, approximately $13.7 million was reported within our United States mechanical construction and facilities services segment, and approximately $1.3 million was reported within our United States building services segment. There were no increases in total estimated costs or reductions to anticipated contract value that had a significant impact on our operating results during each of the years ended December 31, 2021 and 2020. Additionally, there were no significant amounts of revenue recognized during the years ended December 31, 2022 or 2021 related to performance obligations satisfied in prior periods. During the year ended December 31, 2020, we recognized revenue of $6.1 million associated with the final settlement of contract value for two projects within our United States electrical construction and facilities services segment that were completed or substantially completed in prior periods. Due to the significant judgments utilized in the estimation process described above, if subsequent actual results and/or updated assumptions, estimates, or projections related to our underlying project positions were to change from those utilized at December 31, 2022, it could result in a material impact to our results of operations. For example, a 50 basis point increase or decrease in the estimated gross profit margin on our uncompleted construction projects, in the aggregate, as a result of a revision in estimated costs to complete a performance obligation or a revision in estimated transaction price, would have resulted in an increase or decrease to operating income of nearly $90 million for the year ended December 31, 2022. See Note 3 - Revenue from Contracts with Customers of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data for further disclosure regarding revenue recognition.

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. The amounts discussed 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. During 2022, we acquired six companies for total consideration of $100.8 million. Such acquisitions include: (a) a company that provides electrical construction services in the Greater Boston area, the results of operations of which have been included in our United States electrical construction and facilities services segment, and (b) five companies that enhance our presence in geographies where we have existing operations, the results of operations of which were de minimis, consisting of: (i) two companies that provide fire protection services in the Northeastern and Southern regions of the United States, respectively, and that have been included within our United States mechanical construction and facilities services segment, (ii) two companies that specialize in either building automation and controls or mechanical services in the Southwestern and Southern regions of the United States, respectively, and that have been included within our United States building services segment, and (iii) a company that provides electrical construction services in the Midwestern region of the United States and that has been included within our United States electrical construction and facilities services segment. 23 We acquired eight companies during 2021 for total consideration of $131.2 million. Such acquisitions include: (a) two companies, the results of operations of which were de minimis, included within our United States mechanical construction and facilities services segment, consisting of: (i) a company that provides mechanical services within the Southern region of the United States and (ii) a company that provides fire protection services in the Midwestern region of the United States, (b) two companies that provide electrical construction services for a broad array of customers in the Midwestern region of the United States, the results of operations of which have been included in our United States electrical construction and facilities services segment, and (c) four companies included within our United States building services segment, consisting of: (i) a company that provides mobile mechanical services across North Texas and (ii) three companies, the results of operations of which were de minimis, that enhance our presence in geographies where we have existing operations and provide either mobile mechanical services or building automation and controls solutions. Companies acquired in 2022 and 2021 generated incremental revenues of $149.7 million and incremental operating income of $3.9 million, inclusive of $7.3 million of amortization expense associated with identifiable intangible assets, for the year ended December 31, 2022.

Total operations$8,847,421 100 %$7,459,299 100 % Our remaining performance obligations at December 31, 2023 were $8.85 billion compared to $7.46 billion at December 31, 2022. The increase in remaining performance obligations year-over-year was attributable to an increase in remaining performance obligations within: (a) each of our United States construction segments, driven by the award of various projects within the majority of the market sectors in which we operate, and (b) our United States building services segment, largely due to increased project opportunities within its mechanical services division. From a market sector perspective, we experienced the most significant growth in remaining performance obligations within: (a) the high-tech manufacturing market sector, inclusive of projects for customers engaged in: (i) the design and manufacturing of semiconductors, and (ii) the production and development of electric vehicles and/or lithium batteries, (b) the network and communications market sector, driven by data center construction projects, (c) the institutional market sector, and (d) the water and wastewater market sector, due to the award of several construction projects within the Southeastern region of the United States. Remaining performance obligations increased by $23.7 million as a result of acquisitions during 2023. These increases were partially offset by a reduction in remaining performance obligations from the commercial market sector, primarily given the completion of several warehouse and distribution center projects. While the continued growth in our remaining performance obligations is largely due to the strength in demand for our services, a portion of this increase can likely be attributed to external market factors such as material and labor inflation, which has increased the price of certain of our project work. See Note 3 - Revenue from Contracts with Customers of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data for further disclosure regarding our remaining performance obligations.

2022 versus 2021 For discussion and analysis of results of operations for the year ended December 31, 2022 compared to the year ended December 31, 2021, refer to Item 7.

Cash Flows The following table presents a summary of our operating, investing, and financing cash flows (in thousands): 20232022 Net cash provided by operating activities$899,655 $497,933

Increase (decrease) in cash, cash equivalents, and restricted cash $332,682 $(365,500) During the year ended December 31, 2023, our cash balance, including cash equivalents and restricted cash, increased by $332.7 million from $457.1 million at December 31, 2022 to $789.8 million at December 31, 2023. Changes in our cash position from December 31, 2022 to December 31, 2023 are described in further detail below. For a discussion of the changes in our cash position from December 31, 2021 to December 31, 2022, refer to the Liquidity and Capital Resources section included in Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations of our Form 10-K for the year ended December 31, 2022. Operating Activities - Operating cash flows generally represent our net income as adjusted for certain non-cash items and changes in assets and liabilities. For 2023, net cash provided by operating activities was approximately $899.7 million compared to approximately $497.9 million of net cash provided by operating activities in 2022. The $401.7 million increase in operating cash flows during 2023, when compared to 2022, was largely a result of increased income, coupled with customer deposits and advanced payments on certain construction contracts, as evidenced by the growth in our contract liabilities. 30 Investing Activities - Investing cash flows consist primarily of payments for the acquisition of businesses, capital expenditures, and proceeds from the sale or disposal of property, plant, and equipment. During 2023, we utilized approximately $161.3 million of cash for investing activities compared to $140.8 million during 2022. The increase in investing cash outflows year-over-year was primarily driven by higher capital expenditures to support our organic growth, partially offset by an increase in proceeds from the sale or disposal of property, plant, and equipment. Payments for the acquisition of businesses were fairly consistent each year as we utilized $96.5 million in 2023, compared to $98.7 million in 2022. 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 during 2023 was $412.1 million compared to $710.1 million during 2022. The $298.1 million reduction in financing cash outflows was primarily due to a decrease in funds used for the repurchase of our common stock during 2023, partially offset by an increase in net repayments of debt under our credit agreement. 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 12 - Common Stock of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data. We currently pay a regular quarterly dividend of $0.18 per share. For the years ended December 31, 2023 and 2022, cash payments related to dividends were $32.7 million and $27.2 million, respectively. Subsequent to December 31, 2023, our Board of Directors announced its intention to increase the regular quarterly dividend to $0.25 per share commencing with the dividend to be paid in April 2024. 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 $18.9 million variance between the years ended December 31, 2023 and 2022 was a direct result of favorable exchange rate movements for the British pound versus the United States dollar.

We do not have any other material financial guarantees or off-balance sheet arrangements other than those disclosed herein. Other Items To help mitigate the impacts of greenhouse gas emissions on climate change, EMCOR has established initial carbon-based fuel consumption and greenhouse gas emission reduction targets, and has committed to investigating the establishment of science-based greenhouse gas emissions targets. Although to date we have not incurred any material costs or capital expenditures associated with achieving our targets, we could be required to expend amounts in future periods as we continue to work towards our goals. It is not possible, at this time, to estimate the impact that future costs and/or capital expenditures may have on our business, financial condition, results of operations, or liquidity.

2023 versus 2022 Overview The following table presents selected financial data for the fiscal years ended December 31, 2023 and 2022 (in thousands, except percentages and per share data):

Due to the inherent uncertainties involved in making estimates, our assumptions may change in future periods. Estimates and assumptions made for purposes of our goodwill impairment testing may prove to be inaccurate predictions of the future, and other factors used in assessing fair value, such as the weighted average cost of capital, are outside the control of management. Unfavorable changes in certain of these key assumptions may affect future testing results. For example, keeping all other assumptions constant, a 50 basis point increase in the weighted average cost of capital would cause the estimated fair values of our United States electrical construction and facilities services segment, our United States mechanical construction and facilities services segment, our United States building services segment, and our United States industrial services segment to decrease by approximately $115.2 million, $249.9 million, $84.2 million, and $25.2 million, respectively. In addition, keeping all other assumptions constant, a 50 basis point reduction in the perpetual growth rate would cause the estimated fair values of our United States electrical construction and facilities services segment, our United States mechanical construction and facilities services segment, our United States building services segment, and our United States industrial services segment to decrease by approximately $56.5 million, $137.1 million, $40.4 million, and $9.3 million, respectively. Given the amounts by which the fair value exceeds the carrying value for each of our reporting units, the decreases in estimated fair values described above would not have significantly impacted the results of our 2023 impairment tests. Further, for each of our reporting units, a 10% decline in the estimated fair value of such reporting unit, due to other changes in our assumptions, including forecasted future cash flows, would not have significantly impacted the results of our 2023 impairment tests.

Goodwill, Identifiable Intangible Assets, and Other Long-Lived Assets Goodwill As of December 31, 2023 and 2022, we had goodwill of $956.5 million and $919.2 million, respectively, arising out of the acquisition of businesses. Goodwill is not amortized but instead allocated to its respective reporting unit and evaluated for impairment annually, or more frequently if events or circumstances indicate that the carrying amount of goodwill may be impaired. We have determined that our reporting units are consistent with the reportable segments identified in Note 18 - Segment Information of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data. As of December 31, 2023, approximately 18.6% of our goodwill related to our United States electrical construction and facilities services segment, approximately 33.3% related to our United States mechanical construction and facilities services segment, approximately 36.2% related to our United States building services segment, and approximately 11.9% related to our United States industrial services segment. 34 Absent any earlier identified impairment indicators, we perform our annual goodwill impairment assessment on October 1 each fiscal year. Qualitative indicators that may trigger the need for interim quantitative impairment testing include, among others, a deterioration in macroeconomic conditions, declining financial performance, deterioration in the operational environment, or an expectation of selling or disposing of a portion of a reporting unit. Additionally, an interim impairment test may be triggered by a significant change in business climate, a loss of a significant customer, increased competition, or a sustained decrease in share price. In assessing whether our goodwill is impaired, we compare the fair value of the reporting unit to its carrying amount, including goodwill. If the fair value exceeds the carrying amount, no impairment is recognized. However, if the carrying amount of the reporting unit exceeds the fair value, the goodwill of the reporting unit is impaired and an impairment loss in the amount of the excess is recognized and charged to operations. We performed our annual impairment assessment of all reporting units as of October 1, 2023 and determined there was no impairment of goodwill. Based on these impairment assessments, the fair values of our United States electrical construction and facilities services segment, our United States mechanical construction and facilities services segment, our United States building services segment, and our United States industrial services segment exceeded their carrying values by approximately $1,724.3 million, $4,411.7 million, $1,048.0 million, and $89.1 million, respectively. As part of such annual testing, we compared the aggregate fair value of our reporting units to our market capitalization, noting that such comparison supported the reasonableness of the key assumptions utilized in determining the fair value of each of our reporting units. In completing our annual impairment assessment, we determined the fair value of each of our reporting units using an income approach whereby fair value was calculated utilizing discounted estimated future cash flows, assuming a risk-adjusted industry weighted average cost of capital. The weighted average cost of capital used in our annual impairment testing was 10.9% for our United States construction segments, 11.2% for our United States building services segment, and 11.0% for our United States industrial services segment. These weighted average cost of capital estimates were developed with the assistance of an independent third-party valuation specialist and reflect the overall level of inherent risk within the respective reporting unit and the rate of return a market participant would expect to earn. Our cash flow projections were derived from our most recent internal forecasts of anticipated revenue growth rates and operating margins, with cash flows beyond the discrete forecast period estimated using a terminal value calculation which incorporated historical and forecasted trends, an estimate of long-term growth rates, and assumptions about the future demand for our services. The perpetual growth rate used for our annual testing was 2.5% for all of our reporting units.

Other Considerations As referenced above, impairment testing is based upon assumptions and estimates determined by management from a review of our operating results and business plans as well as forecasts of anticipated growth rates and margins, among other considerations. In addition, estimates of weighted average costs of capital are developed with the assistance of an independent third-party valuation specialist. These assumptions and estimates may change in future periods, especially in times of uncertain economic conditions and rising interest rates. Significant adverse changes to external market conditions or our internal forecasts, if any, could result in future impairment charges, particularly with respect to our United States industrial services segment given that the fair value of this reporting unit more closely approximates its carrying value. It is not possible at this time to determine if any future impairment charge will result or, if it does, whether such a charge would be material to our results of operations. Refer to Note 8 - Goodwill, Identifiable Intangible Assets, and Other Long-Lived Assets of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data for further information about our goodwill and identifiable intangible assets as well as our impairment testing. No impairment of our goodwill, identifiable intangible assets, or other long-lived assets was recognized during the years ended December 31, 2022 or 2021.

Discussion and Analysis of Results of Operations Revenues The following table presents our revenues for each of our operating segments and the approximate percentages that each segment's revenues were of total revenues for the years ended December 31, 2023 and 2022 (in thousands, except for percentages):

Accounts Receivable and Allowance for Credit Losses Accounts receivable are recognized in the period we deliver goods or provide services to our customers or when our right to consideration is unconditional. The Company maintains an allowance for credit losses to reduce outstanding receivables to their net realizable value. A considerable amount of judgment is required when determining expected credit losses. Estimates of such losses are recorded when we believe a customer, or group of customers, may not be able to meet their financial obligations due to deterioration in financial condition or credit rating. Factors relevant to our assessment include our prior collection history with our customers, the related aging of past due balances, projections of credit losses based on historical trends in credit quality indicators or past events, and forecasts of future economic conditions. In addition to monitoring delinquent accounts, management reviews the credit quality of its receivables by, among other things, obtaining credit ratings of significant customers, assessing economic and market conditions, and evaluating material changes to a customer's business, cash flows, and financial condition. At December 31, 2022 and 2021, our accounts receivable of $2,567.4 million and $2,204.5 million, respectively, were recorded net of allowances for credit losses of $22.4 million and $23.5 million, respectively. The decrease in our allowance for credit losses was attributable to the write-off of specific amounts deemed uncollectible, partially offset by the provision for credit losses recorded during 2022. We have adjusted our allowance for credit losses during 2022 to account for the impact of changing economic conditions, including rising interest rates. Allowances for credit losses are based on the best facts available and are reassessed and adjusted on a regular basis as additional information is received. The provision for credit losses during 2022, 2021, and 2020 amounted to approximately $5.2 million, $8.0 million, and $3.3 million, respectively. The decrease in the provision for credit losses for the year ended December 31, 2022, when compared to the year ended December 31, 2021, was a result of the impact, in 2021, of $5.8 million of reserves established in connection with two customer bankruptcies within our United States industrial services segment. Such reduction was partially offset by incremental expense taken during 2022, which primarily resulted from the aforementioned change in economic conditions. Should anticipated collections fail to materialize, or if future economic conditions compare unfavorably to our forecasts, we could experience an increase in our allowances for credit losses. For example, if economic conditions were to significantly deteriorate, such as to those experienced during the last global financial crisis, the portion of our allowance for credit losses, which is estimated based on our historical credit loss experience, could increase by up to approximately $12.5 million. 34

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. The amounts discussed 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. During 2022, we acquired six companies for total consideration of $100.8 million. Such acquisitions include: (a) a company that provides electrical construction services in the Greater Boston area, the results of operations of which have been included in our United States electrical construction and facilities services segment, and (b) five companies that enhance our presence in geographies where we have existing operations, the results of operations of which were de minimis, consisting of: (i) two companies that provide fire protection services in the Northeastern and Southern regions of the United States, respectively, and that have been included within our United States mechanical construction and facilities services segment, (ii) two companies that specialize in either building automation and controls or mechanical services in the Southwestern and Southern regions of the United States, respectively, and that have been included within our United States building services segment, and (iii) a company that provides electrical construction services in the Midwestern region of the United States and that has been included within our United States electrical construction and facilities services segment. 23 We acquired eight companies during 2021 for total consideration of $131.2 million. Such acquisitions include: (a) two companies, the results of operations of which were de minimis, included within our United States mechanical construction and facilities services segment, consisting of: (i) a company that provides mechanical services within the Southern region of the United States and (ii) a company that provides fire protection services in the Midwestern region of the United States, (b) two companies that provide electrical construction services for a broad array of customers in the Midwestern region of the United States, the results of operations of which have been included in our United States electrical construction and facilities services segment, and (c) four companies included within our United States building services segment, consisting of: (i) a company that provides mobile mechanical services across North Texas and (ii) three companies, the results of operations of which were de minimis, that enhance our presence in geographies where we have existing operations and provide either mobile mechanical services or building automation and controls solutions. Companies acquired in 2022 and 2021 generated incremental revenues of $149.7 million and incremental operating income of $3.9 million, inclusive of $7.3 million of amortization expense associated with identifiable intangible assets, for the year ended December 31, 2022.

Goodwill, Identifiable Intangible Assets, and Other Long-Lived Assets Goodwill As of December 31, 2021 and 2020, we had goodwill of $890.3 million and $851.8 million, respectively, arising out of the acquisition of businesses. Goodwill is not amortized but instead allocated to its respective reporting unit and evaluated for impairment annually, or more frequently if events or circumstances indicate that the carrying amount of goodwill may be impaired. We have determined that our reporting units are consistent with the reportable segments identified in Note 18 - Segment Information of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data. As of December 31, 2021, approximately 17.9% of our goodwill related to our United States electrical construction and facilities services segment, approximately 34.2% related to our United States mechanical construction and facilities services segment, approximately 35.1% related to our United States building services segment, and approximately 12.8% related to our United States industrial services segment. We performed our annual impairment assessment of all reporting units as of October 1, 2021 and determined there was no impairment of goodwill. Based on these impairment assessments, the fair values of our United States electrical construction and facilities services segment, our United States mechanical construction and facilities services segment, our United States building services segment, and our United States industrial services segment exceeded their carrying values by approximately $1,516.1 million, $2,772.7 million, $784.2 million, and $40.6 million, respectively. In completing our annual impairment assessment, we determined the fair value of each of our reporting units using an income approach whereby fair value was calculated utilizing discounted estimated future cash flows, assuming a risk-adjusted industry weighted average cost of capital. The weighted average cost of capital used in our annual impairment testing was 10.4% for our United States construction segments and our United States building services segment, and 11.3% for our United States industrial services segment. These weighted average cost of capital estimates were developed with the assistance of an independent third-party valuation specialist and reflect the overall level of inherent risk within the respective reporting unit and the rate of return a market participant would expect to earn. Our cash flow projections were derived from our most recent internal forecasts of anticipated revenue growth rates and operating margins, with cash flows beyond the discrete forecast period estimated using a terminal value calculation which incorporated historical and forecasted trends, an estimate of long-term growth rates, and assumptions about the future demand for our services. The perpetual growth rate used for our annual testing was 2.0% for all of our reporting units. Due to the inherent uncertainties involved in making estimates, our assumptions may change in future periods. Estimates and assumptions made for purposes of our goodwill impairment testing may prove to be inaccurate predictions of the future, and other factors used in assessing fair value, such as the weighted average cost of capital, are outside the control of management. Unfavorable changes in certain of these key assumptions may affect future testing results. For example, keeping all other assumptions constant, a 50 basis point increase in the weighted average cost of capital would cause the estimated fair values of our United States electrical construction and facilities services segment, our United States mechanical construction and facilities services segment, our United States building services segment, and our United States industrial services segment to decrease by approximately $103.6 million, $185.5 million, $74.5 million, and $25.9 million, respectively. In addition, keeping all other assumptions constant, a 50 basis point reduction in the perpetual growth rate would cause the estimated fair values of our United States electrical construction and facilities services segment, our United States mechanical construction and facilities services segment, our United States building services segment, and our United States industrial services segment to decrease by approximately $52.4 million, $95.9 million, $35.8 million, and $9.5 million, respectively. Given the amounts by which the fair value exceeds the carrying value for each of our reporting units, the decreases in estimated fair values described above would not have significantly impacted the results of our impairment tests. Further, for each of our reporting units, other than our United States industrial services segment, a 10% decline in the estimated fair value of such reporting unit, due to other changes in our assumptions, including forecasted future cash flows, would not have significantly impacted the results of our impairment tests. In the case of our United States industrial services segment, however, such a 10% decrease would cause the estimated fair value of this reporting unit to approximate its carrying value.

Cost of sales and gross profit The following table presents cost of sales, gross profit (revenues less cost of sales), and gross profit margin (gross profit as a percentage of revenues) for the years ended December 31, 2022 and 2021 (in thousands, except for percentages):

Selling, general and administrative expenses The following table presents selling, general and administrative expenses and SG&A margin (selling, general and administrative expenses as a percentage of revenues) for the years ended December 31, 2022 and 2021 (in thousands, except for percentages):

20222021 Selling, general and administrative expenses$1,038,717 $970,937 SG&A margin9.4 %9.8 % Our selling, general and administrative expenses for the year ended December 31, 2022 were $1,038.7 million compared to selling, general and administrative expenses of $970.9 million for the year ended December 31, 2021. For the year ended December 31, 2022, selling, general and administrative expenses included $17.2 million of incremental expenses directly related to companies acquired in 2022 and 2021, including amortization expense attributable to identifiable intangible assets of $4.5 million. Excluding incremental expenses from businesses acquired, our selling, general and administrative expenses increased by $50.6 million for the year ended December 31, 2022. The organic increase in selling, general and administrative expenses was primarily attributable to an increase in: (a) salaries and related employment expenses, largely as a result of an increase in headcount to support our organic revenue growth, (b) incentive compensation expense within those of our reportable segments which had higher operating results than in the prior year, (c) travel and entertainment expenses, given a resumption in travel and business meals as COVID-19 related restrictions have eased, (d) rent and other occupancy costs driven by: (i) the expansion or addition of certain fabrication facilities, which support our operations, and (ii) the impact of inflation on the real estate market, and (e) computer hardware and software costs, as a result of various information technology and cybersecurity initiatives currently in process. Selling, general and administrative expenses as a percentage of revenues were 9.4% and 9.8% for 2022 and 2021, respectively. The year-over-year decrease in SG&A margin was largely a result of an increase in revenues without a commensurate increase in overhead costs, as we were able to leverage our existing overhead cost structure.

Operating income (loss) The following table presents by segment our operating income (loss) and each segment's operating margin (operating income (loss) as a percentage of such segment's revenues) for the years ended December 31, 2022 and 2021 (in thousands, except for percentages):

Other items Interest expense was $13.2 million and $6.1 million for 2022 and 2021, respectively, and interest income was $2.8 million and $0.9 million for 2022 and 2021, respectively. The increase in both interest expense and interest income for 2022 resulted from higher average interest rates when compared to 2021. In addition, the increase in interest expense was attributable to greater average outstanding borrowings year-over-year. Our income tax provision for the year ended December 31, 2022 was $152.6 million, based on an income tax rate of 27.3%, compared to an income tax provision and an income tax rate of $145.6 million and 27.5%, respectively, for the year ended December 31, 2021. The increase in our income tax provision for 2022 was due to increased income before income taxes, while the slight decrease in our income tax rate for 2022 was attributable to the favorable impact of certain discrete tax items.

Liquidity and Capital Resources The following section discusses our principal liquidity and capital resources, as well as our primary liquidity requirements and sources and uses of cash. We are focused on the efficient conversion of operating income into cash to provide for the Company's material cash requirements, including working capital needs, investment in our growth strategies through business acquisitions and capital expenditures, satisfaction of contractual commitments, including principal and interest payments on our outstanding indebtedness, and shareholder return through dividend payments and share repurchases. We strive to maintain a balanced approach to capital allocation in order to achieve growth, deliver value, and minimize risk. Management monitors financial markets and overall economic conditions for factors that may affect our liquidity and capital resources and adjusts our capital allocation strategy as necessary. Negative macroeconomic trends could have an adverse effect on future liquidity if we experience delays in the payment of outstanding receivables beyond normal payment terms, an increase in credit losses, or significant increases in the price of commodities or the materials and equipment utilized for our project and service work, beyond those experienced to date. In addition, during economic downturns, there have typically been fewer small discretionary projects from the private sector and our competitors have aggressively bid larger long-term infrastructure and public sector contracts. Our liquidity is also impacted by: (a) the type and length of construction contracts in place, as performance of long duration contracts typically requires greater amounts of working capital, (b) the level of turnaround activities within our United States industrial services segment, as such projects are billed in arrears pursuant to contractual terms that are standard within the industry, and (c) the billing terms of our maintenance contracts, including those within our United States and United Kingdom building services segments. While we strive to negotiate favorable billing terms, which allow us to invoice in advance of costs incurred on certain of our contracts, there can be no assurance that such terms will be agreed to by our customers. As of December 31, 2022, we had cash and cash equivalents, excluding restricted cash, of $456.4 million, which are maintained in depository accounts and highly liquid investments with original maturity dates of three months or less. Both our short-term and long-term liquidity requirements are expected to be met through our cash and cash equivalent balances, cash generated from our operations, and, as necessary, the borrowing capacity under our revolving credit facility. Our credit agreement provides for a $1.30 billion revolving credit facility, for which there is $1.23 billion of available capacity as of December 31, 2022. Refer to Note 9 - Debt of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data for further information regarding our credit agreement. Based upon our current credit rating and financial position, we can also reasonably expect to be able to secure long-term debt financing if required to achieve our strategic objectives; however, no assurances can be made that such debt financing will be available on favorable terms. We believe that we have sufficient financial resources available to meet our short-term and foreseeable long-term liquidity requirements.

Decrease in cash, cash equivalents, and restricted cash$(365,500)$(80,994) For the year ended December 31, 2022, our cash balance, including cash equivalents and restricted cash, decreased by $365.5 million from $822.6 million at December 31, 2021 to $457.1 million at December 31, 2022. Changes in our cash position from December 31, 2021 to December 31, 2022 are described in further detail below. For a discussion of the changes in our cash position from December 31, 2020 to December 31, 2021, refer to the Liquidity and Capital Resources section included in Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations of our Form 10-K for the year ended December 31, 2021. Operating Activities - Operating cash flows generally represent our net income as adjusted for certain non-cash items and changes in assets and liabilities. For 2022, net cash provided by operating activities was approximately $497.9 million compared to approximately $318.8 million of net cash provided by operating activities in 2021. The $179.1 million increase in operating cash flows during 2022, when compared to 2021, was primarily a result of the collection of advanced billings on certain of our uncompleted construction projects, as evidenced in part by the growth in our contract liabilities, net of the increase in outstanding accounts receivable. 30 Investing Activities - Investing cash flows consist primarily of payments for the acquisition of businesses, capital expenditures, and proceeds from the sale or disposal of property, plant, and equipment. For 2022, we utilized approximately $140.8 million of cash for investing activities compared to $153.1 million in 2021. The decrease in investing cash outflows year-over-year was primarily driven by a decrease in payments for business acquisitions, partially offset by higher capital expenditures used to invest in organic growth. 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 for 2022 was $710.1 million compared to $245.5 million in 2021. The increase in cash used in financing activities in 2022, when compared to 2021, was primarily due to the increase in funds used for the repurchase of our common stock. During the year ended December 31, 2022, cash payments related to share repurchases were $660.6 million compared to $195.5 million for the year ended December 31, 2021. 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 12 - Common Stock of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data. We currently pay a regular quarterly dividend of $0.15 per share. For the years ended December 31, 2022 and 2021, cash payments related to dividends were $27.2 million and $28.2 million, respectively. Subsequent to December 31, 2022, our Board of Directors announced its intention to increase the regular quarterly dividend to $0.18 per share commencing with the dividend to be paid in April 2023. 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 $11.2 million variance between the years ended December 31, 2022 and 2021 was a direct result of unfavorable exchange rate movements for the British pound versus the United States dollar.

Material Cash Requirements from Contractual and Other Obligations As of December 31, 2022, 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 December 31, 2022, there were no direct borrowings outstanding under our revolving credit facility and the amount outstanding under our term loan was $242.8 million. We are required to make annual principal payments on our term loan of $13.9 million on December 31 of each year until maturity. All remaining unpaid amounts are due on March 2, 2025, when the credit agreement governing our term loan and revolving credit facility expires. Until such time, we are required to make periodic interest payments on our outstanding indebtedness. Future interest payments will be determined based on prevailing interest rates during that time, which are anticipated to increase in the near term. Refer to Note 9 - Debt of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data for further detail of our debt obligations, including our term loan and 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 $325.7 million at December 31, 2022, with $78.3 million payable within the next 12 months. Refer to Note 16 - Leases of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data for further detail surrounding our lease obligations and the timing of expected future payments. Open Purchase Obligations - As of December 31, 2022, we had $2.24 billion of open purchase obligations, of which payments totaling approximately $1.94 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 2 - Summary of Significant Accounting Policies of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data, we have loss payment deductibles and/or self-insured retentions for certain insurance matters. As of December 31, 2022, our insurance liabilities, net of estimated recoveries, were $201.5 million. Of this net amount, approximately $38.8 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. 31 Retirement Plan Obligations - As of December 31, 2022, expected future payments relating to our defined benefit post retirement plans were approximately $1.5 million per year. We provide funding to our post retirement plans based on at least the minimum funding required by applicable regulations. In determining the minimum funding required, we utilize current actuarial assumptions and exchange rates to forecast amounts that may be payable. In our judgment, minimum funding estimates cannot be reliably estimated beyond a five-year time horizon. Refer to Note 14 - Retirement Plans of the notes to consolidated financial statements in Item 8. Financial Statements and Supplementary Data for further information about our post retirement plans. 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 December 31, 2022, the present value of expected future payments relating to these contingent consideration arrangements was $16.9 million. Of this amount, $10.0 million is estimated as being payable during 2023, with the remainder due pursuant to the terms of our contractual agreements some of which extend through 2025.

We do not have any other material financial guarantees or off-balance sheet arrangements other than those disclosed herein. Other Items To help mitigate the impacts of greenhouse gas emissions on climate change, EMCOR has established initial carbon-based fuel consumption and greenhouse gas emission reduction targets, and has committed to setting science-based targets. Although to date we have not incurred any material costs or capital expenditures associated with achieving our targets, we could be required to expend amounts in future periods as we continue to work towards our goals. During 2022, EMCOR purchased carbon credits totaling 31,000 metric tons, for approximately $0.2 million. It is not possible, at this time, to estimate the impact that future costs and/or capital expenditures may have on our business, financial condition, results of operations, or liquidity.

2022 versus 2021 Overview The following table presents selected financial data for the fiscal years ended December 31, 2022 and 2021 (in thousands, except percentages and per share data):

Insurance Liabilities We have loss payment deductibles for certain workers' compensation, automobile liability, general liability, and property claims, have self-insured retentions for certain other casualty claims, and are self-insured for employee-related healthcare claims. In addition, we maintain a wholly-owned captive insurance subsidiary to manage certain of our insurance liabilities. Losses are recorded based upon estimates of our liability for claims incurred and for claims incurred but not reported. The liabilities are derived from known facts, historical trends, and industry averages, utilizing the assistance of an independent third-party actuary to determine the best estimate for the majority of these obligations. We believe the liabilities recognized on the Consolidated Balance Sheets for these obligations are adequate. However, such obligations are difficult to assess and estimate due to numerous factors, including severity of injury, determination of liability in proportion to other parties, timely reporting of occurrences, and effectiveness of safety and risk management programs. Therefore, if our actual experience differs from the assumptions and estimates used for recording the liabilities, adjustments may be required and will be recorded in the period that the experience becomes known. In addition, as discussed above, an increase in the cost to settle insurance claims could result in higher insurance costs and deductibles. Our estimated net insurance liabilities for workers' compensation, automobile liability, general liability, and property claims increased by $22.9 million for the year ended December 31, 2022 compared to the year ended December 31, 2021, partially as a result of greater potential exposures and an increase in certain of our deductibles or self-insured retentions. If our estimated insurance liabilities for workers' compensation, automobile liability, general liability, and property claims were to increase by 10%, it would have resulted in $20.1 million of additional expense for the year ended December 31, 2022.

Income Taxes As of December 31, 2022 and 2021, we had net deferred income tax liabilities of $61.6 million and $51.0 million, respectively, primarily resulting from differences between the carrying value and income tax bases of certain identifiable intangible assets, goodwill, and depreciable fixed assets. Included within these net deferred income tax liabilities are $211.9 million and $212.3 million of deferred income tax assets as of December 31, 2022 and 2021, respectively. The total valuation allowance on deferred income tax assets was approximately $3.6 million and $2.5 million as of December 31, 2022 and 2021, respectively. The ultimate realization of deferred income tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Based on our taxable income, which has generally exceeded the amount of our net deferred income tax asset balance, as well as current projections of future taxable income, we have determined that it is more likely than not that our net deferred income tax assets will be realized. However, revisions to our forecasts or declining macroeconomic conditions could result in changes to our assessment of the realization of these deferred income tax assets. Refer to Note 11 - Income Taxes of the notes to consolidated financial statements in Item 8. Financial Statements and Supplementary Data for further detail regarding our deferred income taxes.

Identifiable Intangible Assets and Other Long-Lived Assets As of December 31, 2022 and 2021, net identifiable intangible assets (primarily consisting of our customer relationships, subsidiary trade names, developed technology/vendor network, and contract backlog) arising out of the acquisition of businesses were $594.0 million and $589.4 million, respectively. The determination of related estimated useful lives for identifiable intangible assets and whether those assets are impaired involves significant judgments based upon short- and long-term projections of future performance. These forecasts reflect assumptions regarding anticipated macroeconomic conditions as well as our ability to successfully integrate acquired businesses. Absent earlier indicators of impairment, we test for impairment of subsidiary trade names that are not subject to amortization on an annual basis (October 1). In addition, we review for impairment of identifiable intangible assets that are being amortized as well as other long-lived assets whenever facts and circumstances indicate that their carrying values may not be fully recoverable. As of October 1, 2022, we performed our annual impairment testing of all subsidiary trade names that are not subject to amortization and determined that there was no impairment of these assets. In performing this impairment assessment, we considered the sensitivity of the reported amounts to the methods, assumptions, and estimates underlying our testing. For example, we performed sensitivity analyses and concluded that, individually, none of the following changes in estimates or assumptions would have significantly impacted the results of our testing or resulted in a material impairment of our subsidiary trade names: (a) a 50 basis point increase in the discount rate utilized in our testing, (b) a 50 basis point decline in the perpetual growth rate utilized in our testing, or (c) a 10% decrease in the estimated fair value of each trade name. With respect to identifiable intangible assets that are being amortized as well as other long-lived assets, no impairment was recognized during the year ended December 31, 2022. 36

Other Considerations As referenced above, impairment testing is based upon assumptions and estimates determined by management from a review of our operating results and business plans as well as forecasts of anticipated growth rates and margins, among other considerations. In addition, estimates of weighted average costs of capital are developed with the assistance of an independent third-party valuation specialist. These assumptions and estimates may change in future periods. Significant adverse changes to external market conditions or our internal forecasts, if any, could result in future impairment charges, particularly with respect to our United States industrial services segment given that the fair value of this reporting unit more closely approximates its carrying value. It is not possible at this time to determine if any future impairment charge will result or, if it does, whether such a charge would be material to our results of operations. Refer to Note 8 - Goodwill, Identifiable Intangible Assets, and Other Long-Lived Assets of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data for further information about our goodwill and identifiable intangible assets as well as our impairment testing, including the $232.8 million of impairment charges recorded during the year ended December 31, 2020. For the year ended December 31, 2021, no impairment of our goodwill, identifiable intangible assets, or other long-lived assets was recognized.

Discussion and Analysis of Results of Operations Revenues The following table presents our revenues for each of our operating segments and the approximate percentages that each segment's revenues were of total revenues for the years ended December 31, 2022 and 2021 (in thousands, except for percentages):
