NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1 – Business, Basis of Presentation and Significant Accounting Policies

Nature of the Business

MasTec, Inc. (collectively with its subsidiaries, “MasTec” or the “Company”) is a leading infrastructure construction company operating mainly throughout North America across a range of industries. The Company’s primary activities include the engineering, building, installation, maintenance and upgrade of communications, energy, utility and other infrastructure, such as: power delivery services, including transmission, distribution, environmental planning and compliance; wireless, wireline/fiber and customer fulfillment activities; power generation, primarily from clean energy and renewable sources; pipeline distribution infrastructure, including natural gas, carbon capture sequestration, water and pipeline integrity services; heavy civil; industrial infrastructure; and environmental remediation services. MasTec’s customers are primarily in these industries. MasTec reports its results under five reportable segments: (1) Communications; (2) Clean Energy and Infrastructure; (3) Oil and Gas; (4) Power Delivery and (5) Other.

Basis of Presentation

The accompanying consolidated financial statements are unaudited and have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and with the instructions for Form 10-Q and Rule 10-01 of Regulation S-X. Pursuant to these rules and regulations, certain information and footnote disclosures normally included in the annual audited consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. The accompanying consolidated balance sheet as of December 31, 2022 is derived from the Company’s audited financial statements as of that date. Because certain information and footnote disclosures have been condensed or omitted, these consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto as of and for the year ended December 31, 2022 contained in the Company’s 2022 Annual Report on Form 10-K (the “2022 Form 10-K”). In management’s opinion, all normal and recurring adjustments considered necessary for a fair presentation of the financial position, results of operations and cash flows for the periods presented have been included. When appropriate, prior year amounts are reclassified to conform with the current period presentation. Interim period operating results do not necessarily indicate the results that may be expected for any other interim period or for the full fiscal year. The Company believes that the disclosures made in these consolidated financial statements are adequate to make the information not misleading.

Principles of Consolidation

The accompanying consolidated financial statements include MasTec, Inc. and its subsidiaries and include the accounts of all majority owned subsidiaries over which the Company exercises control and, when applicable, entities in which the Company has a controlling financial interest. All significant intercompany balances and transactions have been eliminated in consolidation. Other parties’ interests in entities that MasTec consolidates are reported as non-controlling interests within equity, except for mandatorily redeemable non-controlling interests, which are recorded within other liabilities. Net income or loss attributable to non-controlling interests is reported as a separate line item below net income or loss. Investments in entities for which the Company does not have a controlling financial interest, but over which it has the ability to exert significant influence, are accounted for under the equity method of accounting. For equity investees in which the Company has an undivided interest in the assets, liabilities and profits or losses of an unincorporated entity, but does not exercise control over the entity, the Company consolidates its proportional interest in the accounts of the entity.

Translation of Foreign Currencies

The assets and liabilities of foreign subsidiaries with a functional currency other than the U.S. dollar are translated into U.S. dollars at period-end exchange rates, with resulting translation gains or losses included within other comprehensive income or loss. Revenue and expenses are translated into U.S. dollars at average rates of exchange during the applicable period. Substantially all of the Company’s foreign operations use their local currency as their functional currency. For foreign operations for which the local currency is not the functional currency, the operation’s non-monetary assets are remeasured into U.S. dollars at historical exchange rates. All other accounts are remeasured at current exchange rates. Gains or losses from remeasurement are included in other income or expense, net. Currency gains or losses resulting from transactions executed in currencies other than the functional currency are included in other income or expense, net.

In these consolidated financial statements, “$” means U.S. dollars unless otherwise noted.

Management Estimates

The preparation of consolidated financial statements in accordance with U.S. GAAP requires the use of estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. These estimates are based on historical experience and various other assumptions that management believes to be reasonable under the circumstances, including the potential future effects of macroeconomic trends and events, such as inflation and interest rate levels; uncertainty from potential market volatility; supply chain disruptions; climate-related matters; other market, industry and regulatory factors, including permitting issues; global events, such as military conflicts; and public health matters. These estimates form the basis for making judgments about the Company’s operating results and the carrying values of assets and liabilities that are not readily apparent from other sources. While management believes that such estimates are reasonable when considered in conjunction with the Company’s consolidated financial position and results of operations taken as a whole, actual results could differ materially from these estimates.

Key estimates include: the recognition of revenue and project profit or loss, which the Company defines as project revenue less project costs of revenue, including project-related depreciation, in particular, on construction contracts accounted for under the cost-to-cost method, for which the recorded amounts require estimates of costs to complete and the amount and probability of variable consideration included in the contract

transaction price; fair value estimates, including acquisition-related assets, such as goodwill and intangible assets, equity investments, long-lived and other assets; acquisition-related liabilities, including contingent consideration, other liabilities and debt obligations; allowances for credit losses; asset lives used in computing depreciation and amortization; fair values of financial instruments; self-insurance liabilities; certain other accruals and allowances; income taxes; and the estimated effects of litigation and other contingencies.

General Economic, Market and Regulatory Conditions

The Company has experienced, and may continue to experience, direct and indirect negative effects on its business and operations from negative economic, market, and regulatory conditions, including permitting issues, market interest rates, inflationary effects on fuel prices, labor and materials costs, supply chain disruptions, and uncertainty from potential market volatility that could negatively affect demand for future projects and/or delay existing project timing or cause increased project costs. The extent to which general economic, market and regulatory conditions could affect the Company’s business, operations and financial results is uncertain as it will depend upon numerous evolving factors that management may not be able to accurately predict, and, therefore, any future impacts on the Company’s business, financial condition and/or results of operations cannot be quantified or predicted with specificity.

Significant Accounting Policies

Revenue Recognition

The Company recognizes revenue from contracts with customers when, or as, control of promised services and goods is transferred to customers. The amount of revenue recognized reflects the consideration to which the Company expects to be entitled in exchange for the services and goods transferred. The Company primarily recognizes revenue over time utilizing the cost-to-cost measure of progress, which best depicts the continuous transfer of control of goods or services to the customer, and correspondingly, when performance obligations are satisfied for the related contracts.

Contracts. The Company derives revenue primarily from construction projects performed under: (i) master service and other service agreements, which generally provide a menu of available services in a specific geographic territory that are utilized on an as-needed basis, and are typically priced using either a time and materials or a fixed price per unit basis; and (ii) contracts for specific projects requiring the construction and installation of an entire infrastructure system, or specified units within an infrastructure system, which are subject to multiple pricing options, including fixed price, unit price, time and materials, or cost plus a markup. Revenue derived from projects performed under master service and other service agreements totaled 43% and 54% of consolidated revenue for the three month periods ended June 30, 2023 and 2022, respectively, and totaled 45% and 56% for the six month periods ended June 30, 2023 and 2022, respectively.

For certain master service and other service agreements, revenue is recognized at a point in time, primarily for install-to-the-home and certain other wireless services in the Company’s Communications segment, and to a lesser extent, certain revenue in the Company’s Clean Energy and Infrastructure and Oil and Gas segments. Point in time revenue is recognized when the work order has been fulfilled, which, for the majority of the Company’s point in time revenue, is the same day it is initiated. Point in time revenue accounted for approximately 3% of consolidated revenue for both the three and six month periods ended June 30, 2023, and totaled approximately 4% for both the three and six month periods ended June 30, 2022.

The total contract transaction price and cost estimation processes used for recognizing revenue over time under the cost-to-cost method is based on the professional knowledge and experience of the Company’s project managers, engineers, operational and financial professionals. Management reviews estimates of total contract transaction price and total project costs on an ongoing basis. Changes in job performance, job conditions and management’s assessment of expected variable consideration are factors that influence estimates of the total contract transaction price, total costs to complete those contracts and the Company’s profit recognition. Changes in these factors could result in revisions to revenue in the period in which the revisions are determined, which revisions could materially affect the Company’s consolidated results of operations for that period. Provisions for losses on uncompleted contracts are recorded in the period in which such losses are determined. For the six month periods ended June 30, 2023 and 2022, project profit was affected by less than 5% as a result of changes in contract estimates included in projects that were in process as of December 31, 2022 and 2021. Changes in recognized revenue, net, as a result of changes in total contract transaction price estimates, including from variable consideration, and/or changes in cost estimates, related to performance obligations satisfied or partially satisfied in prior periods, for the three month period ended June 30, 2023 positively affected revenue by approximately 1.5%, and for the three month period ended June 30, 2022, there was no net effect. For the six month periods ended June 30, 2023 and 2022, such net changes positively affected revenue by approximately 0.6% and 0.2%, respectively.

Performance Obligations. A performance obligation is a contractual promise to transfer a distinct good or service to a customer. The transaction price of a contract is allocated to each distinct performance obligation and recognized as revenue when or as the performance obligation is satisfied. The majority of the Company’s performance obligations are completed within one year.

Remaining performance obligations represent the amount of unearned transaction prices under contracts for which work is wholly or partially unperformed, including the Company’s share of unearned transaction prices from its proportionately consolidated non-controlled joint ventures. As of June 30, 2023, the amount of the Company’s remaining performance obligations was $8.0 billion. Based on current expectations, the Company anticipates it will recognize approximately $4.6 billion of its remaining performance obligations as revenue during 2023, with the majority of the remaining balance expected to be recognized in 2024.

Variable Consideration. Transaction prices for the Company’s contracts may include variable consideration, which comprises items such as change orders, claims and incentives. Management estimates variable consideration for a performance obligation utilizing estimation methods that it believes best predict the amount of consideration to which the Company will be entitled. Management’s estimates of variable consideration and the determination of whether to include estimated amounts in transaction prices are based largely on specific discussions, correspondence or preliminary negotiations and past practices with the customer, engineering studies and legal advice and all other relevant information that is reasonably available at the time of the estimate. To the extent unapproved change orders, claims and other variable consideration reflected in transaction prices are not

resolved in the Company’s favor, or to the extent incentives reflected in transaction prices are not earned, there could be reductions in, or reversals of, previously recognized revenue.

As of June 30, 2023 and December 31, 2022, the Company included in its contract transaction prices approximately $317 million and $271 million, respectively, of change orders and/or claims for certain contracts that were in the process of being resolved in the ordinary course of business, including through negotiation, arbitration and other proceedings. These transaction price adjustments, when earned, are included within contract assets or accounts receivable, net of allowance, as appropriate. As of both June 30, 2023 and December 31, 2022, these change orders and/or claims primarily related to certain projects in the Company’s Clean Energy and Infrastructure and Power Delivery segments and include amounts related to recently acquired businesses. The Company actively engages with its customers to complete the final approval process and generally expects these processes to be completed within one year. Amounts ultimately realized upon final agreement by customers could be higher or lower than such estimated amounts.

Recent Accounting Pronouncements

The discussion below describes the effects of recent accounting pronouncements, as updated from the discussion in the Company’s 2022 Form 10-K.

Accounting Pronouncements Adopted in 2023

In October 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers (“ASU 2021-08”) to improve consistency for revenue recognition in the post-acquisition period for acquired contracts as compared to contracts entered into subsequent to acquisition. ASU 2021-08 requires an acquirer to recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606, Revenue from Contracts with Customers, rather than at fair value. ASU 2021-08, which the Company adopted in the first quarter of 2023, did not have a material effect on the Company’s consolidated financial statements.

Recently Issued Accounting Pronouncements

In March 2023, the FASB issued ASU 2023-01, Leases (Topic 842): Common Control Arrangements (“ASU 2023-01”) to improve the guidance for applying Topic 842, Leases, to arrangements between entities under common control. ASU 2023-01 improves current GAAP by clarifying the accounting for leasehold improvements associated with common control leases, thereby reducing diversity in practice. The provisions of this ASU that apply to public companies include a requirement for entities to amortize leasehold improvements associated with common control leases over the useful life of the common control group. ASU 2023-01 is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2023, with early adoption permitted. The Company is currently evaluating the effects of this ASU, however, this ASU is not expected to have a material effect on the Company’s consolidated financial statements.

Note 2 – Earnings Per Share

Basic earnings or loss per share is computed by dividing net income or loss attributable to MasTec by the weighted average number of common shares outstanding for the period, which excludes non-participating unvested restricted share awards. Diluted earnings per share is computed by dividing net income attributable to MasTec by the weighted average number of fully diluted shares, as calculated primarily under the treasury stock method, which includes the potential effect of dilutive common stock equivalents, such as issued but unvested restricted shares. If the Company reports a loss, rather than income, the computation of diluted loss per share excludes the effect of dilutive common stock equivalents, if their effect would be anti-dilutive.

The following table provides details underlying the Company’s earnings per share calculations for the periods indicated (in thousands):


	For the Three Months Ended June 30,				For the Six Months Ended June 30,
	2023		2022		2023		2022
Net income (loss) attributable to MasTec:
Net income (loss) - basic (a)	$	15,542	$	16,212	$	(64,998)	$	(18,766)
Fair value gain related to resolved contingent payments (b)	$	—	$	1,025	$	—	$	1,025
Net income (loss) - diluted (a)	$	15,542	$	15,187	$	(64,998)	$	(19,791)
Weighted average shares outstanding:
Weighted average shares outstanding - basic(c)	77,635		74,445		77,306		74,615
Dilutive common stock equivalents (d)(e)	737		1,092		—		32
Weighted average shares outstanding - diluted	78,372		75,537		77,306		74,647

(a)Basic net income or loss is calculated as total net income or loss, less amounts attributable to non-controlling interests. Diluted net income or loss is calculated as total net income or loss, less amounts attributable to non-controlling interests, adjusted for the fair value gain or loss, if any, related to additional contingent payments to the former owners of an acquired business for which the contingency has been resolved as of the respective period. See Note 3 - Acquisitions, Goodwill and Other Intangible Assets, Net, for additional information.

(b)For the three and six month periods ended June 30, 2022, represents the fair value gain related to additional contingent payments for which the contingency had been resolved as of June 30, 2022. See Note 3 – Acquisitions, Goodwill and Other Intangible Assets, Net for additional information.

(c)For the three month periods ended June 30, 2023 and 2022, basic shares include approximately 88,000 and 132,000 weighted average shares, respectively, related to additional contingent payments, and for the six month periods ended June 30, 2023 and 2022, basic shares include approximately 88,000 and 101,000 of such weighted average shares, respectively.

(d)For the three month periods ended June 30, 2023, and 2022, weighted average anti-dilutive common stock equivalents totaled approximately 2,000 and 178,000 shares, respectively, and for the six month periods ended June 30, 2023 and 2022, such shares totaled approximately 1,147,000 and 1,273,000, respectively.

(e)For the three and six month periods ended June 30, 2023, weighted average common stock equivalents related to additional contingent payments to the former owners of an acquired business, which shares were anti-dilutive, were de minimis, and for the three and six month periods ended June 30, 2022, weighted average common stock equivalents related to such additional contingent payments, which shares were dilutive, totaled approximately 1,000 and 32,000, respectively.

Share repurchases. There were no share repurchases under the Company’s share repurchase programs in either of the three or six month periods ended June 30, 2023. For the three and six month periods ended June 30, 2022, the Company repurchased approximately 936,000 and 1,124,000 shares of its common stock, respectively, the effect of which on the Company’s weighted average shares outstanding for the respective periods was a reduction of approximately 554,000 and 330,000 shares. See Note 11 - Equity for details of the Company’s share repurchase transactions.

Shares issued for acquisitions. In the fourth quarter of 2022, the Company issued approximately 2,758,000 shares of its common stock in conjunction with the October 2022 acquisition of Infrastructure and Energy Alternatives, Inc. (“IEA”). In the second quarter of 2022, the Company issued 133,000 shares in connection with the December 2021 acquisition of Henkels & McCoy Holdings, Inc., formerly known as Henkels & McCoy Group, Inc. (“HMG”). See Note 3 - Acquisitions, Goodwill and Other Intangible Assets, Net for additional information.

Note 3 – Acquisitions, Goodwill and Other Intangible Assets, Net

The following table provides a reconciliation of changes in goodwill by reportable segment for the six month period ended June 30, 2023 (in millions):


	Communications		Clean Energy and Infrastructure		Oil and Gas		Power Delivery		Total Goodwill
Goodwill, gross, as of December 31, 2022	$	606.1	$	703.3	$	582.2	$	270.1	$	2,161.7
Accumulated impairment loss (a)	—		—		(116.7)		—		(116.7)

(a) Accumulated impairment losses include the effects of currency translation gains and/or losses.

(b) Measurement period adjustments represent adjustments, net, to preliminary estimates of fair value within the measurement period of up to one year from the date of acquisition. Measurement period adjustments, net, for the six month period ended June 30, 2023 were primarily the result of updated valuations of certain fixed assets and updated estimates of certain assets and liabilities, including contract assets and liabilities. As a result of certain of these adjustments, depreciation expense decreased by approximately $6 million, revenue increased by approximately $13 million and costs of revenue, excluding depreciation and amortization decreased by approximately $3 million.

The following table provides a reconciliation of changes in other intangible assets, net, for the period indicated (in millions):


	Other Intangible Assets, Net
	Customer Relationships and Backlog		Trade Names (a)		Other (b)		Total
Other intangible assets, gross, as of December 31, 2022	$	1,089.4	$	228.9	$	86.6	$	1,404.9
Accumulated amortization	(388.8)		(28.9)		(40.9)		(458.6)
Other intangible assets, net, as of December 31, 2022	$	700.6	$	200.0	$	45.7	$	946.3


Currency translation adjustments	—		—		0.5		0.5
Amortization expense	(69.7)		(10.1)		(4.2)		(84.0)
Other intangible assets, net, as of June 30, 2023	$	630.9	$	189.9	$	42.0	$	862.8

(a)Includes approximately $34.5 million of non-amortizing trade names as of both June 30, 2023 and December 31, 2022.

(b)Consists principally of pre-qualifications and non-compete agreements.

Quarterly Assessment for Indicators of Impairment. During the second quarter of 2023, the Company performed a quarterly review for indicators of impairment, which considered its results for the six month period ended June 30, 2023, together with its expectations of future results, including consideration of the potential effects of shifts in timing for projects and macroeconomic factors. In conjunction with this quarterly review, management performed a quantitative assessment of the goodwill associated with one reporting unit within the Clean Energy and Infrastructure segment. Based on the results of this assessment, management determined that the estimated fair value of this reporting unit substantially exceeded its carrying value as of June 30, 2023. Significant changes in the assumptions or estimates used in management’s assessment, such as a reduction in profitability and/or cash flows, changes in market or other conditions, including decreases in project activity levels and/or the effects of elevated levels of inflation or market interest rates, could result in non-cash impairment charges to goodwill and indefinite-lived intangible assets in the future.

Recent Acquisitions

The Company seeks to grow and diversify its business both organically and through acquisitions and/or strategic arrangements in order to deepen its market presence and customer base, broaden its geographic reach and expand its service offerings. In 2021, the Company initiated a significant transformation of its end-market business operations to focus on the nation’s transition to low-carbon energy sources and position the Company for expected future opportunities. This transformation has included significant business combination activity, including expansion of the Company’s scale and capacity in renewable energy, power delivery, heavy civil and telecommunications services, which activity has resulted in significant acquisition and integration costs, both in the Company’s existing and recently acquired operations. Acquisitions are funded with cash on hand, borrowings under the Company’s senior unsecured credit facility and other debt financing and, for certain recent acquisitions, with shares of the Company’s common stock, and are generally subject to customary purchase price adjustments.

2023 Acquisitions. For the six month period ended June 30, 2023, MasTec acquired certain of the assets of a telecommunications company specializing in wireless services that is included within the Company’s Communications segment, which acquisition was effective in January and has been accounted for as a business combination under ASC 805, “Business Combinations” (“ASC 805”). Determination of the estimated fair values of the net assets acquired and consideration transferred for this acquisition was preliminary as of June 30, 2023; as a result, further adjustments to these estimates may occur. Additionally, MasTec acquired 68% and 42% of the equity interests of two equipment companies, both of which are accounted for as asset acquisitions under ASC 805, and were effective in May and included within the Company’s Oil and Gas segment. Based on an evaluation of the respective entities’ operating agreements, under which the Company has voting control with respect to the entities’ operating management, the Company determined that it has control over these entities, and, therefore, has consolidated these entities within the Company’s results of operations, with the other parties’ interests accounted for as non-controlling interests. The aggregate purchase price of the Company’s 2023 acquisitions was composed of approximately $62 million in cash, net of cash acquired.

2022 Acquisitions. During 2022, MasTec completed five acquisitions, which included all of the equity interests of the following: (i) within the Company’s Clean Energy and Infrastructure segment: IEA, a leading utility-scale infrastructure solutions provider in North America, with expertise in renewable energy and heavy civil projects, as well as rail and environmental remediation services, which acquisition was effective in October; and a company specializing in the production of concrete and aggregate products, which acquisition was effective in August; (ii) within the Company’s Oil and Gas segment: an infrastructure construction company focusing on water, sewer and utility projects and with expertise in excavation and site work, which acquisition was effective in January; (iii) within the Company’s Communications segment: a telecommunications company specializing in wireline services, which acquisition was effective as of the end of May; and (iv) within the Company’s Power Delivery segment: a company specializing in the construction of overhead high voltage transmission lines, which acquisition was effective in July.

Determination of the estimated fair values of the net assets acquired and the estimated earn-out liabilities and consideration transferred for three of the Company’s 2022 acquisitions was preliminary as of June 30, 2023 while the Company finalizes certain working capital and other valuation and contingency-related estimates; as a result, further adjustments to such estimates may occur. The following table summarizes, as of June 30, 2023, the estimated fair values of the consideration paid and net assets acquired, as adjusted, for the Company’s 2022 acquisitions (in millions):


Acquisition consideration:	IEA		All other		Total
Cash, net of cash acquired	$	564.5	$	48.4	$	612.9
Shares transferred	173.7		—		173.7
Estimated fair value of warrants	10.3		—		10.3
Estimated fair value of contingent consideration	—		2.8		2.8
Total consideration	$	748.5	$	51.2	$	799.7
Identifiable assets acquired and liabilities assumed:
Accounts receivable and contract assets	$	585.7	$	6.1	$	591.8
Current assets	36.1		1.5		37.6
Property and equipment	213.0		30.1		243.1
Long-term assets, primarily operating lease right-of-use assets	40.6		0.3		40.9
Amortizing intangible assets	362.2		5.9		368.1
Accounts payable	(136.5)		(4.6)		(141.1)
Current liabilities, including current portion of operating lease liabilities	(444.6)		(2.9)		(447.5)
Long-term debt, including finance lease obligations	(330.8)		(0.2)		(331.0)
Long-term liabilities, primarily operating lease liabilities and deferred income taxes	(131.4)		(0.2)		(131.6)
Total identifiable net assets	$	194.3	$	36.0	$	230.3
Goodwill	554.2		15.2		569.4
Total net assets acquired, including goodwill	$	748.5	$	51.2	$	799.7

Amortizing intangible assets related to the IEA acquisition are primarily composed of customer relationships, and to a lesser extent, trade names and backlog. Customer relationship and trade name intangible assets for IEA, in the aggregate, totaled approximately $321 million, which each had a weighted average life of approximately 14 years based on IEA’s operational history and established relationships with, and the nature of, its customers, which are primarily in the renewable energy and specialty civil industries. Backlog intangible assets for IEA totaled approximately

$42 million with a weighted average life of approximately 1 year based on estimated cash flows expected to be derived from future work on acquired contracts with customers. The weighted average life of amortizing intangible assets in the aggregate for the IEA acquisition was 13 years. Amortizing intangible assets related to “All other” acquisitions are primarily composed of customer relationships with an aggregate weighted average life of 9 years. Amortizing intangible assets are amortized in a manner consistent with the pattern in which the related benefits are expected to be consumed.

The goodwill balances for each of the respective acquisitions represent the estimated values of each acquired company’s geographic presence in key markets, assembled workforce, management team’s industry-specific project management expertise and synergies expected to be achieved from the combined operations of each of the acquired companies and MasTec. Approximately $38 million of the goodwill balance related to the 2022 acquisitions is expected to be tax deductible as of June 30, 2023.

The shares of MasTec common stock included in consideration transferred for IEA in the table above consist of approximately 2.7 million shares, valued at approximately $174 million based on the market price of MasTec common stock on the date of closing. Total cash paid for acquisitions, net, includes approximately $44 million of cash acquired. Long-term debt in the table above includes $300 million aggregate principal balance of 6.625% senior unsecured notes that were assumed in connection with the acquisition of IEA. See Note 7 - Debt for additional information.

Consideration transferred for IEA includes the value of certain warrants that were originally issued by IEA, for which the remaining outstanding warrants as of December 31, 2022 had an estimated fair value of $3.1 million. Under the terms of the IEA merger agreement, holders of the IEA warrants became entitled to receive an amount in cash and shares of MasTec common stock upon exercise of the IEA warrants. The number of MasTec shares issued in connection with exercises of such IEA warrants in the first quarter of 2023 was de minimis. All remaining IEA warrants expired unexercised on March 26, 2023. Fair value gains related primarily to the expired warrants totaled approximately $2.6 million for the six month period ended June 30, 2023, which amount is reflected in other income.

Contingent consideration included in the table above is composed of earn-out liabilities, which generally equal a portion of the acquired companies’ earnings before interest, taxes, depreciation and amortization (“EBITDA”) in excess of thresholds agreed upon with the sellers, if applicable. The earn-out arrangements for the 2022 acquisitions are payable annually and have five-year terms, as set forth in the respective purchase agreements, and were valued at approximately $3 million in the aggregate. Earn-outs are recorded within other current and other long-term liabilities, as appropriate, in the consolidated balance sheets. See Note 4 - Fair Value of Financial Instruments for details pertaining to fair value estimates for the Company’s earn-out arrangements. As of June 30, 2023, the range of remaining potential undiscounted earn-out liabilities for the 2022 acquisitions was estimated to be up to $4 million; however, there is no maximum payment amount. Current liabilities reflected in the table above include contingent liabilities for insurance and other matters.

HMG Additional Payments. The HMG purchase agreement, for which the subject acquisition was effective in December 2021, provides for certain additional payments to be made to the sellers if certain acquired receivables are collected by the Company (the “Additional Payments”). Pursuant to the terms of the purchase agreement, a portion of the Additional Payments will be made in cash, with the remainder due in shares of MasTec common stock. The estimated number of potential shares that could be issued related to such Additional Payments will be based on the amounts ultimately collected and the share price as defined within the purchase agreement. Changes in the estimated fair value of potential shares that could be issued, which result from changes in MasTec’s share price as compared with the share price as defined within the purchase agreement, are reflected within other income or expense, as appropriate. For the three and six month periods ended June 30, 2023, unrealized fair value measurement activity related to the contingent shares totaled losses of approximately $3.8 million and $5.4 million, respectively. For both the three and six month periods ended June 30, 2022, unrealized fair value measurement activity related to the contingent shares totaled a gain of approximately $3.2 million. An Additional Payment of approximately $29.4 million was made in May 2022, which payment was composed of approximately $18 million in cash and 133,157 shares of MasTec common stock.

As of June 30, 2023 and December 31, 2022, the estimated fair value of remaining Additional Payments totaled approximately $40 million and $37 million, respectively, which amounts are included within other current liabilities in the consolidated balance sheet. For the six month period ended June 30, 2023, the estimated fair value of remaining Additional Payments included the effect of unrealized fair value losses related to the contingent shares of approximately $5.4 million and a reduction of approximately $2.4 million from changes in collections attributed to acquired balances. The estimated number of shares that would be paid in connection with the remaining Additional Payment liability totaled approximately 160,000 and 170,000 shares as of June 30, 2023 and December 31, 2022, respectively. Of the total remaining Additional Payments as of June 30, 2023, the amount due to the sellers, based on amounts collected as of June 30, 2023, totaled approximately $19.4 million, of which the amount due in shares totaled approximately $10.4 million, or 87,900 shares. See Note 2 - Earnings Per Share for the effect of the above referenced shares on the Company’s earnings per share calculations.

Pro forma results. For the three month periods ended June 30, 2023 and 2022, unaudited supplemental pro forma revenue totaled approximately $2.9 billion and $3.0 billion, respectively, and unaudited supplemental pro forma net income totaled approximately $14.5 million and $27.2 million, respectively. For the six month periods ended June 30, 2023 and 2022, unaudited supplemental pro forma revenue totaled approximately $5.4 billion and $5.3 billion, respectively, and unaudited supplemental pro forma net loss totaled approximately $68.7 million and $47.4 million, respectively. Supplemental pro forma information for the Company’s first quarter 2023 acquisition has not been presented for the pre-acquisition periods due to the impracticability of obtaining accurate or reliable historical financial information for the assets of the entity that was acquired.

Acquisition-related results. For the three and six month periods ended June 30, 2023, the Company’s consolidated results of operations included acquisition-related revenue of approximately $569.7 million and $970.3 million, respectively, including a total of approximately $520.6 million and $890.6 million, respectively, for IEA. For the three and six month periods ended June 30, 2022, the Company’s consolidated results of operations included acquisition-related revenue of approximately $602.3 million and $1,307.0 million, respectively, including a total of approximately $480.4 million and $1,028.5 million, respectively, for HMG and INTREN in the aggregate. For the three and six month periods ended June 30, 2023, the Company’s consolidated results of operations included acquisition-related net losses of approximately $13.3 million and $41.5

million, respectively, based on the Company’s consolidated effective tax rates, and for the three and six month periods ended June 30, 2022, the Company’s consolidated results of operations included acquisition-related net income of approximately $18.7 million and $9.4 million, respectively, based on the Company’s consolidated effective tax rates. These acquisition-related results include amortization of acquired intangible assets and certain acquisition integration costs, and exclude the effects of interest expense associated with consideration paid for the related acquisitions.

Acquisition and integration costs. The Company has incurred certain acquisition and integration costs in connection with its recent acquisitions, which costs are included within general and administrative expenses, costs of revenue, excluding depreciation and amortization, and other expense, as appropriate. Acquisition and integration costs include: i) the costs of integrating acquired entities, such as: employee termination expenses, including employee compensation relating to the elimination of certain positions that were determined to be redundant, and other integration-type costs, including operating cost redundancies, facility consolidation expenses, lease termination expenses, losses on disposal of identified assets, system migration expenses, training and other integration costs; and ii) legal, professional and other fees associated with the consummation of these acquisitions, including fees paid in connection with certain transaction-related financing commitments, including, in the second half of 2022, bridge financing related to the IEA acquisition. The Company is currently in the process of integrating these acquisitions and expects to incur additional acquisition and integration expenses. For the three and six month periods ended June 30, 2023, such acquisition and integration costs totaled approximately $22.7 million and $39.8 million, respectively, of which $20.4 million and $35.0 million, respectively, was included within general and administrative expenses, and $2.3 million and $4.8 million, respectively, was included within costs of revenue, excluding depreciation and amortization, for the respective periods. Acquisition and integration costs for the three and six month periods ended June 30, 2022 totaled approximately $12.5 million and $26.1 million, respectively, which amounts were included within general and administrative expenses. As of June 30, 2023 and December 31, 2022, approximately $7.0 million and $5.5 million, respectively, was included within current liabilities within the consolidated balance sheets related to such costs.

Note 4 – Fair Value of Financial Instruments

The Company’s financial instruments are primarily composed of cash and cash equivalents, accounts and notes receivable, cash collateral deposited with insurance carriers, life insurance assets, equity investments, certain other assets and investments, deferred compensation plan assets and liabilities, accounts payable and other current liabilities, acquisition-related contingent consideration and other liabilities, mandatorily redeemable non-controlling interests and debt obligations.

Fair value is the price that would be received to sell an asset or the amount paid to transfer a liability, also referred to as the “exit price,” in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value guidance establishes a valuation hierarchy, which requires maximizing the use of observable inputs when measuring fair value. The three levels of inputs that may be used are: (i) Level 1 - quoted market prices in active markets for identical assets or liabilities; (ii) Level 2 - observable market-based inputs or other observable inputs; and (iii) Level 3 - significant unobservable inputs that cannot be corroborated by observable market data, which are generally determined using valuation models incorporating management estimates of market participant assumptions.

Acquisition-Related Contingent Consideration and Other Liabilities

Acquisition-related contingent consideration and other liabilities is composed of earn-outs, which represent the estimated fair value of future amounts payable for businesses, including for mandatorily redeemable non-controlling interests (together, “Earn-outs”), that are contingent upon the acquired business achieving certain levels of earnings in the future. As of June 30, 2023 and December 31, 2022, the estimated fair value of the Company’s Earn-out liabilities totaled $99.2 million and $127.4 million, respectively, of which $0.7 million and $13.9 million, respectively, related to mandatorily redeemable non-controlling interests. Earn-out liabilities included within other current liabilities totaled approximately $31.5 million and $37.7 million as of June 30, 2023 and December 31, 2022, respectively. The fair values of the Company’s Earn-out liabilities are estimated using income approaches such as discounted cash flows or option pricing models, both of which incorporate significant inputs not observable in the market (Level 3 inputs), including management’s estimates and entity-specific assumptions, and are evaluated on an ongoing basis. Key assumptions include the discount rate, which was 12.0% as of June 30, 2023, and probability-weighted projections of earnings before interest, taxes, depreciation and amortization (“EBITDA”). Significant changes in any of these assumptions could result in significantly higher or lower potential Earn-out liabilities. The ultimate payment amounts for the Company’s Earn-out liabilities will be determined based on the actual results achieved by the acquired businesses. As of June 30, 2023, the range of potential undiscounted Earn-out liabilities was estimated to be between $16 million and $121 million; however, there is no maximum payment amount.

Earn-out activity consists primarily of additions from new business combinations; changes in the expected fair value of future payment obligations; and payments. For both the three and six month periods ended June 30, 2023, there were no additions from new business combinations. For the three month period ended June 30, 2022, there were no additions from new business combinations, and additions for the six month period ended June 30, 2022 totaled approximately $1.7 million. There were no measurement period adjustments in either of the three or six month periods ended June 30, 2023. Measurement period adjustments totaled an increase of approximately $3.4 million for the three month period ended June 30, 2022 and related to the Company’s Oil and Gas segment, and for the six month period ended June 30, 2022, totaled an increase, net, of approximately $1.5 million and related to a net increase in the Company’s Oil and Gas segment, partially offset by a decrease in its Communications segment. For the three and six month periods ended June 30, 2023, fair value adjustments totaled a decrease, net, of approximately $1.8 million and $2.1 million, respectively, and related to a net decrease in the Company’s Communications segment, partially offset by a net increase, primarily within the Company’s Clean Energy and Infrastructure and Oil and Gas segments. The decrease in the Communications segment included a reduction of approximately $11.6 million related to mandatorily redeemable non-controlling interests for both periods. For both the three and six month periods ended June 30, 2022, fair value adjustments totaled a decrease, net, of approximately $1.3 million and related primarily to the Company’s Communications segment. For the three and six month periods ended June 30, 2023, Earn-out payments totaled approximately $24.5 million and $26.1 million, respectively, including approximately $1.7 million related to mandatorily redeemable non-controlling interests for the six month period ended June 30, 2023. For both the three and six month periods ended June 30, 2022, Earn-out payments totaled $26.8 million.

Equity Investments

The Company’s equity investments as of June 30, 2023 include: (i) the Company’s 33% equity interests in Trans-Pecos Pipeline, LLC (“TPP”) and Comanche Trail Pipeline, LLC (“CTP,” and together with TPP, the “Waha JVs”); (ii) a 15% equity interest in Cross Country Infrastructure Services, Inc. (“CCI”); (iii) the Company’s 50% equity interests in each of FM Technology Holdings, LLC, FM USA Holdings, LLC and All Communications Solutions Holdings, LLC, collectively “FM Tech”; (iv) the Company’s interests in certain proportionately consolidated non-controlled contractual joint ventures; and (v) certain other equity investments.

Investment Arrangements. From time to time, the Company may participate in selected investment or strategic arrangements, including equity interests in various business entities and participation in contractual joint ventures, some of which may involve the extension of loans or other types of financing arrangements. The Company has determined that certain of its investment arrangements are variable interest entities (“VIEs”). As of June 30, 2023, except for one individually insignificant VIE, the Company does not have the power to direct the primary activities that most significantly impact the economic performance of its VIEs, nor is it the primary beneficiary. Accordingly, except for the previously mentioned VIE, the Company’s VIEs are not consolidated. The carrying values of the Company’s VIEs totaled approximately $26 million and $24 million as of June 30, 2023 and December 31, 2022, respectively, which amounts are recorded within other long-term assets in the consolidated balance sheets, and management believes that the Company’s maximum exposure to loss for its VIEs, inclusive of additional financing commitments, approximated $37 million for both periods.

Equity investments, other than those accounted for as equity method investments or those that are proportionately consolidated, are measured at fair value if their fair values are readily determinable. Equity investments that do not have readily determinable fair values are measured at cost, adjusted for changes from observable market transactions, if any, less impairment, which is referred to as the “adjusted cost basis.” As of June 30, 2023 and December 31, 2022, the aggregate carrying value of the Company’s equity investments, including equity investments measured on an adjusted cost basis, totaled approximately $321 million and $306 million, respectively. As of both June 30, 2023 and December 31, 2022, equity investments measured on an adjusted cost basis, including the Company’s $15 million investment in CCI, totaled approximately $20 million. There were no impairments related to these investments in any of the three or six month periods ended June 30, 2023 or 2022.

The Waha JVs. The Waha JVs own and operate certain pipeline infrastructure that transports natural gas to the Mexican border for export. The Company’s investments in the Waha JVs are accounted for as equity method investments. Equity in earnings related to the Company’s proportionate share of income from the Waha JVs, which is included within the Company’s Other segment, totaled approximately $7.5 million and $15.4 million for the three and six month periods ended June 30, 2023, respectively, and totaled approximately $7.6 million and $15.0 million for the three and six month periods ended June 30, 2022, respectively. Distributions of earnings from the Waha JVs, which are included within operating cash flows, totaled approximately $1.5 million and $5.8 million for the three and six month periods ended June 30, 2023, respectively, and totaled approximately $4.6 million and $7.6 million for the three and six month periods ended June 30, 2022, respectively. Cumulative undistributed earnings from the Waha JVs, which represents cumulative equity in earnings for the Waha JVs less distributions of earnings, totaled $120.2 million as of June 30, 2023. The Company’s net investment in the Waha JVs, which differs from its proportionate share of the net assets of the Waha JVs due primarily to equity method goodwill associated with capitalized investment costs, totaled approximately $273 million and $263 million as of June 30, 2023 and December 31, 2022, respectively.

The Waha JVs are party to separate non-recourse financing facilities, each of which are secured by pledges of the equity interests in the respective entities, as well as a first lien security interest over virtually all of their assets. The Waha JVs are also party to certain interest rate swaps (the “Waha JV swaps”), which are accounted for as qualifying cash flow hedges. The Company reflects its proportionate share of any unrealized fair market value gains or losses from fluctuations in interest rates associated with these swaps within other comprehensive income or loss, as appropriate. For the three and six month periods ended June 30, 2023, the Company’s proportionate share of unrecognized unrealized activity on the Waha JV swaps totaled gains of approximately $6.1 million and $0.5 million, respectively, or $4.6 million and $0.4 million, net of tax, respectively. For the three and six month periods ended June 30, 2022, unrecognized unrealized activity related to the Waha JV swaps totaled gains of approximately $10.4 million and $28.7 million, respectively, or $7.8 million and $21.6 million, net of tax, respectively.

Other Investments. The Company has equity interests in certain telecommunications entities that are accounted for as equity method investments. As of June 30, 2023 and December 31, 2022, the Company had an aggregate investment of approximately $22 million and $21 million, respectively, in these entities, including $18 million for FM Tech as of both periods.

Unbilled receivables	1,496.8		1,328.0
Contract assets	$	1,850.7	$	1,729.9

Contract billings represent the amount of performance obligations that have been billed but not yet collected, whereas contract assets consist of unbilled receivables and retainage. Unbilled receivables represent the estimated value of unbilled work for projects with performance obligations recognized over time. Retainage represents a portion of the contract amount that has been billed, but for which the contract allows the customer to retain a portion of the billed amount until final contract settlement (generally, from 5% to 10% of contract billings). For the six month period ended June 30, 2023, provisions for credit losses totaled a recovery of approximately $0.7 million, and for the six month period ended June 30, 2022, provisions for credit losses totaled approximately $0.5 million. Impairment losses on contract assets were not material in either period.

For the six month periods ended June 30, 2023 and 2022, rent expense for such leases totaled approximately $72.7 million and $67.9 million, respectively, of which $7.6 million and $5.5 million, respectively, represented variable lease costs. The Company also incurred rent expense for leases with terms of one year or less totaling approximately $130.7 million and $53.7 million for the three month periods ended June 30, 2023 and 2022, respectively, and totaling approximately $241.8 million and $159.3 million for the six month periods ended June 30, 2023 and 2022, respectively. Rent expense for operating leases is

generally consistent with the amount of the related payments, which payments are included within operating activities in the consolidated statements of cash flows.

Employee Stock Purchase Plans

The Company has certain employee stock purchase plans (collectively, “ESPPs”), under which shares of the Company’s common stock are available for purchase by eligible participants. Under the ESPPs, eligible participants are permitted to purchase MasTec, Inc. common stock at 85% of the fair market value of the shares on the date of purchase, which occurs on the last trading day of each two week offering period. At the Company’s discretion, share purchases may be satisfied by delivering either newly issued common shares, or common shares reacquired on the open market or in privately negotiated transactions.

For the three month periods ended June 30, 2023 and 2022, 25,353 shares and 31,888 shares, respectively, were purchased by participants under the Company’s ESPPs for $2.1 million and $1.8 million, respectively, and for the six month periods ended June 30, 2023 and 2022, 46,651 shares and 56,625 shares, respectively, were purchased for $3.8 million and $3.6 million, respectively. Shares purchased by participants under the Company’s ESPPs in each of the three and six month periods ended June 30, 2023 and 2022 were reacquired by the Company on the open market. Compensation expense associated with the Company’s ESPPs totaled approximately $0.4 million and $0.3 million for the three month periods ended June 30, 2023 and 2022, respectively, and totaled approximately $0.7 million for both the six month periods ended June 30, 2023 and 2022.

Note 10 – Other Retirement Plans

Multiemployer Plans. Certain of MasTec’s subsidiaries contribute amounts to multiemployer pension and other multiemployer benefit plans and trusts (“MEPPs”). Contributions are generally based on fixed amounts per hour per employee for employees covered under these plans. Multiemployer plan contribution rates are determined annually and are assessed on a “pay-as-you-go” basis based on union employee payrolls. Union payrolls cannot be determined for future periods because the number of union employees employed at a given time, and the plans in which they participate, vary depending upon the location and number of ongoing projects and the need for union resources in connection with those projects. Total contributions to multiemployer plans and the related number of employees covered by these plans for the periods indicated were as follows:


	Multiemployer Plans
	Covered Employees		Contributions (in millions)
	Low	High	Pension		Other Multiemployer		Total
For the Three Months Ended June 30:
2023	7,581	7,727	$	21.3	$	16.5	$	37.8
2022	6,672	7,136	$	22.3	$	13.9	$	36.2
For the Six Months Ended June 30:
2023	6,806	7,727	$	43.1	$	29.9	$	73.0
2022	6,601	7,136	$	39.3	$	27.1	$	66.4

The fluctuations in the number of employees covered under multiemployer plans and associated contributions in the table above related primarily to the timing of activity for the Company’s union resource-based projects, as well as the effects of the Company’s recent acquisitions. For the three and six month periods ended June 30, 2023, multiemployer plan activity was driven primarily by project work within the Company’s Power Delivery operations and acquisition-related project work within the Company’s Clean Energy and Infrastructure operations, whereas for the three and six month periods ended June 30, 2022, activity was driven primarily by acquisition-related project work within the Company’s Power Delivery operations.

Note 11 – Equity

Share Activity

The Company’s share repurchase programs provide for the repurchase, from time to time, of MasTec common shares in open market transactions or in privately negotiated transactions in accordance with applicable securities laws. The Company’s share repurchase programs do not have an expiration date and may be modified or suspended at any time at the Company’s discretion. There were no share repurchases under the Company’s share repurchase programs in either of the three or six month periods ended June 30, 2023. For the three and six month periods ended June 30, 2022, the Company repurchased 0.9 million and 1.1 million shares of its common stock, respectively, under its share repurchase programs for an aggregate purchase price of approximately $67.5 million and $81.3 million, respectively. Of the total repurchased shares, 0.1 million shares were repurchased in the first quarter of 2022 for $8.6 million under the Company’s December 2018 $100 million share repurchase program, which completed the program. The remaining 1.0 million shares were repurchased for $72.7 million under the Company’s March 2020 $150 million share repurchase program. As of June 30, 2023, $77.3 million was available for future share repurchases under the Company’s March 2020 share repurchase program.

Accumulated Other Comprehensive Loss

Unrealized foreign currency translation activity, net, in each of the three and six month periods ended June 30, 2023 and 2022 relates primarily to the Company’s operations in Canada and Mexico. Unrealized investment activity in each of the three and six month periods ended June 30, 2023 and 2022 relates to unrealized fair value gains or losses associated with the Waha JV interest rate swaps. See Note 4 - Fair Value of Financial Instruments for additional information.

Note 12 – Income Taxes

In determining the quarterly provision for income taxes, management uses an estimated annual effective tax rate based on forecasted annual pre-tax income, permanent tax differences, statutory tax rates and tax planning opportunities in the various jurisdictions in which the Company operates. The effect of significant discrete items is separately recognized in the quarter(s) in which they occur. For the three month periods ended June 30, 2023 and 2022, the Company’s consolidated effective tax rates were 14.9% and 10.9%, respectively, and for the six month periods ended June 30, 2023 and 2022 were 39.6% and 37.4%, respectively. The Company’s effective tax rate for the six month period ended June 30, 2023 included the effects of a net tax benefit of approximately $8.9 million related to share-based payment awards offset by an increase in non-deductible expenses, and for the six month period ended June 30, 2022, included a net benefit of approximately $1.0 million related to share-based payment awards as well as a benefit of approximately $2.0 million from the true-up of certain prior year non-deductible expenses.

Note 13 – Segments and Related Information

Segment Discussion

The Company manages its operations under five operating segments, which represent its five reportable segments: (1) Communications; (2) Clean Energy and Infrastructure; (3) Oil and Gas; (4) Power Delivery and (5) Other. This structure is generally focused on broad end-user markets for the Company’s labor-based construction services. All five reportable segments derive their revenue primarily from the engineering, installation and maintenance of infrastructure, primarily in North America.

The Communications segment performs engineering, construction, maintenance and customer fulfillment activities related to communications infrastructure, primarily for wireless and wireline/fiber communications and install-to-the-home customers, as well as infrastructure for utilities, among others. The Clean Energy and Infrastructure segment primarily serves energy, utility, government and other end-markets through the installation and construction of power generation facilities, primarily from clean energy and renewable sources, such as wind, solar, biomass, natural gas and hydrogen, as well as battery storage for renewable energy; various types of heavy civil and industrial infrastructure, including rail; and environmental remediation services. The Company performs engineering, construction, maintenance and other services for pipeline distribution, including natural gas, carbon capture sequestration, water and pipeline integrity and other services for the energy and utilities industries through its Oil and Gas segment. The Power Delivery segment primarily serves the energy and utility industries through the engineering, construction and maintenance of power transmission and distribution infrastructure, including electrical and gas transmission lines, distribution network systems and substations; and environmental planning and compliance services. The Other segment includes certain equity investees, the services of which may vary from those provided by the Company’s primary segments, as well as other small business units that perform construction and other services for certain international end-markets.

Earnings before interest, taxes, depreciation and amortization (“EBITDA”) is the measure of profitability used by management to manage its segments and, accordingly, in its segment reporting. As appropriate, the Company supplements the reporting of its consolidated financial information determined in accordance with U.S. GAAP with certain non-U.S. GAAP financial measures, including EBITDA. The Company believes these non-U.S. GAAP measures provide meaningful information and help investors understand the Company’s financial results and assess its prospects for future performance. The Company uses EBITDA to evaluate its performance, both internally and as compared with its peers, because it excludes certain items that may not be indicative of the Company’s core operating results for its reportable segments, as well as items that can vary widely across different industries or among companies within the same industry. Segment EBITDA is calculated in a manner consistent with consolidated EBITDA.

Summarized financial information for MasTec’s reportable segments is presented and reconciled to consolidated financial information for total MasTec in the following tables, including a reconciliation of consolidated income before income taxes to EBITDA, all of which are presented in millions. The tables below may contain slight summation differences due to rounding.

Foreign Operations and Other. MasTec operates primarily in the United States and Canada, and, to a far lesser extent, in Mexico, the Caribbean and India. Revenue derived from U.S. operations totaled $2.9 billion and $2.3 billion for the three month periods ended June 30, 2023 and

2022, respectively, and totaled $5.4 billion and $4.2 billion for the six month periods ended June 30, 2023 and 2022, respectively. Revenue derived from foreign operations totaled $22.1 million and $51.3 million for the three month periods ended June 30, 2023 and 2022, respectively, and totaled $49.6 million and $75.8 million for the six month periods ended June 30, 2023 and 2022, respectively. Revenue from foreign operations was derived primarily from the Company’s Canadian operations in its Oil and Gas segment. Long-lived assets held in the U.S. included property and equipment, net, of $1.7 billion as of both June 30, 2023 and December 31, 2022, and for the Company’s businesses in foreign countries, totaled $19.4 million and $21.0 million, for the respective periods. Intangible assets and goodwill, net, related to the Company’s U.S. operations totaled approximately $2.9 billion and $3.0 billion as of June 30, 2023 and December 31, 2022, respectively, and for the Company’s businesses in foreign countries, totaled approximately $34.7 million and $35.5 million, respectively. Substantially all of the Company’s long-lived and intangible assets and goodwill in foreign countries relate to its Canadian operations. As of June 30, 2023 amounts due from customers from which foreign revenue was derived accounted for less than 1% of the Company’s consolidated net accounts receivable position, which is calculated as accounts receivable, net, less deferred revenue, and as of December 31, 2022, such amounts accounted for approximately 1% of the Company’s consolidated net accounts receivable position. Revenue from governmental entities for the three and six month periods ended June 30, 2023 totaled approximately 12% and 10%, of total revenue, respectively, and for both the three and six month periods ended June 30, 2022, totaled approximately 7% of total revenue, substantially all of which was derived from the Company’s U.S. operations.

Significant Customers

No customer represented greater than 10% of the Company’s total consolidated revenue in any of the three or six month periods ended June 30, 2023 and 2022.

Note 14 – Commitments and Contingencies

MasTec is subject to a variety of legal cases, claims and other disputes that arise from time to time in the ordinary course of its business, including project contract price and other project disputes, other project-related liabilities and acquisition purchase price disputes. MasTec cannot provide assurance that it will be successful in recovering all or any of the potential damages it has claimed or in defending claims against the Company. The outcome of such cases, claims and disputes cannot be predicted with certainty and an unfavorable resolution of one or more of them could have a material adverse effect on the Company’s business, financial condition, results of operations and cash flows.

Acquired Legacy Solar Matter. On April 28, 2023, a jury found IEA and its subsidiary, IEA Constructors, LLC (“IEAC” and, together with IEA, the “IEA Entities”), liable to plaintiffs H&L Farms LLC, Shaun Harris, and Amie Harris following a trial in the U.S. District Court for the Middle District of Georgia, Columbus Division (the “Court”), against the IEA Entities, IEAC’s customer, Silicon Ranch Corporation (“SRC”), and engineering firm Westwood Professional Services, Inc. The suit, filed in August 2021, arose out of a project that commenced in 2021 involving the construction by IEAC of a solar farm for SRC. The project was constructed on SRC’s property located adjacent to a 1,400 acre tract of land that plaintiffs purchased in March 2021 for approximately $3.3 million.

The plaintiffs brought various causes of action under Georgia law, including trespass, nuisance, and negligence, arising out of the defendants’ alleged failure to exercise appropriate efforts required by Georgia law to prevent and remediate soil erosion and sedimentary run-off that flowed from SRC’s property into a 21-acre lake on plaintiffs’ property. Following trial, the jury awarded Mr. and Mrs. Harris $4.5 million each for loss of use and enjoyment of the lake and awarded H&L Farms (the legal owner) another $1.5 million in remediation costs. These damages were apportioned 30% to SRC, 40% to IEA, and 30% to IEAC. The jury also awarded $25 million in punitive damages against SRC and $50 million in punitive damages against each of the IEA Entities. The Court entered judgment on the verdict and issued an injunction requiring IEAC to remediate the sedimentary run-off as quickly as possible.

Subsequently, the IEA Entities filed a post-trial motion seeking multiple avenues of relief from the verdict, including elimination of all damages against IEA because they believe there was no evidence to support holding it liable, a new trial for both IEA Entities because of serial misconduct of plaintiffs’ counsel, a substantial reduction of the remediation award because it was not supported by the evidence and of the loss of use and enjoyment awards because they far exceed the appraised value of the lake. The motion also seeks a reduction of the punitive damages to $250,000 per plaintiff under Georgia’s statutory cap based on the IEA entities’ belief of an absence of evidence that either of the IEA Entities acted with a specific intent to cause harm and, failing that, to no more than the amount of the compensatory damages left standing after post-trial review. Plaintiffs have filed their opposition to the motion, which is now pending the Court’s ruling.

Following trial, Mr. and Mrs. Harris filed a motion for damages under the Georgia frivolous claim/defense statute, seeking $1 million in damages for each of them in compensation for their ostensible stress in pursuing their claims in litigation and an unspecified amount of attorneys’ fees which could be as much as 45% of any amount of damages remaining after post-verdict review. The IEA Entities have challenged this motion, which is now pending the Court’s determination, on both substantive and procedural grounds.

Other Commitments and Contingencies

Leases. In the ordinary course of business, the Company enters into non-cancelable operating leases for certain of its facility, vehicle and equipment needs, including related party leases. See Note 8 - Lease Obligations and Note 15 - Related Party Transactions.

Letters of Credit. In the ordinary course of business, the Company is required to post letters of credit for its insurance carriers and surety bond providers and in support of performance under certain contracts as well as certain obligations associated with the Company’s equity investments and other strategic arrangements, including its variable interest entities. Such letters of credit are generally issued by a bank or similar financial institution. The letter of credit commits the issuer to pay specified amounts to the holder of the letter of credit under certain conditions. If this were to occur, the Company would be required to reimburse the issuer of the letter of credit, which, depending upon the circumstances, could result in a charge to earnings. As of June 30, 2023 and December 31, 2022, there were $128.2 million and $166.7 million, respectively, of letters of credit issued under the Company’s credit facilities. Letter of credit claims have historically not been material. The Company is not aware of any material claims relating to its outstanding letters of credit as of June 30, 2023 or December 31, 2022.

Performance and Payment Bonds. In the ordinary course of business, MasTec is required by certain customers to provide performance and payment bonds for contractual commitments related to its projects. These bonds provide a guarantee to the customer that the Company will perform under the terms of a contract and that the Company will pay its subcontractors and vendors. If the Company fails to perform under a contract or to pay its subcontractors and vendors, the customer may demand that the surety make payments or provide services under the bond. The Company must reimburse the surety for expenses or outlays it incurs. As of June 30, 2023 and December 31, 2022, outstanding performance and payment bonds approximated $5,389.2 million and $4,855.5 million, respectively, and estimated costs to complete projects secured by these bonds totaled $1,789.7 million and $1,739.9 million, respectively. Included in these balances as of June 30, 2023 and December 31, 2022 are $357.9 million and $115.8 million, respectively, of outstanding performance and payment bonds issued on behalf of the Company’s proportionately consolidated non-controlled contractual joint ventures, representing the Company’s proportionate share of the total bond obligation for the related projects.

Investment and Strategic Arrangements. The Company holds undivided interests, ranging from 85% to 90%, in multiple proportionately consolidated non-controlled contractual joint ventures that provide infrastructure construction services for electrical transmission projects, as well as undivided interests, ranging from 25% to 50%, in each of four civil construction projects, and one 49% undivided interest in pipeline project work. Income and/or losses incurred by these joint ventures are generally shared proportionally by the respective joint venture members, with the members of the joint ventures jointly and severally liable for all of the obligations of the joint venture. The respective joint venture agreements provide that each joint venture partner indemnify the other party for any liabilities incurred by such joint venture in excess of its ratable portion of such liabilities. Thus, it is possible that the Company could be required to pay or perform obligations in excess of its share if the other joint venture partners fail or refuse to pay or perform their respective share of the obligations. As of June 30, 2023, the Company was not aware of material future claims against it in connection with these arrangements. For the six month period ended June 30, 2023, the Company provided $0.5 million of project-related financing to its contractual joint ventures, which amount was outstanding as of June 30, 2023. Included in the Company’s cash balances as of June 30, 2023 and December 31, 2022 are amounts held by entities that are proportionately consolidated totaling $23.2 million and $25.7 million, respectively. These amounts are available to support the operations of those entities, but are not available for the Company’s other operations.

The Company has other investment and strategic arrangements, under which it may incur costs or provide financing, performance, financial and/or other guarantees. See Note 4 - Fair Value of Financial Instruments and Note 15 - Related Party Transactions for additional information pertaining to the Company’s investment and strategic arrangements.

Self-Insurance. MasTec maintains insurance policies for workers’ compensation, general liability and automobile liability, which are subject to per claim deductibles. The Company is self-insured up to the amount of the deductible. The Company also maintains excess umbrella coverage. The Company manages certain of its insurance liabilities indirectly through its wholly-owned captive insurance company, which reimburses claims up to the applicable insurance limits. Captive insurance-related cash balances totaled approximately $0.9 million and $1.1 million as of June 30, 2023 and December 31, 2022, respectively, and are generally not available for use in the Company’s other operations.

As of June 30, 2023 and December 31, 2022, MasTec’s estimated liability for unpaid claims and associated expenses, including incurred but not reported losses related to these policies, totaled $196.0 million and $176.7 million, respectively, of which $123.9 million and $109.3 million, respectively, were reflected within other long-term liabilities in the consolidated balance sheets. MasTec also maintains an insurance policy with respect to employee group medical claims, which is subject to annual per employee maximum losses. MasTec’s estimated liability for employee group medical claims totaled $4.4 million and $4.1 million as of June 30, 2023 and December 31, 2022, respectively.

The Company is required to post collateral, generally in the form of letters of credit, surety bonds and cash to certain of its insurance carriers. Insurance-related letters of credit for the Company’s workers’ compensation, general liability and automobile liability policies amounted to $56.4 million and $95.6 million as of June 30, 2023 and December 31, 2022, respectively. Outstanding surety bonds related to self-insurance programs amounted to $148.6 million and $110.9 million as of June 30, 2023 and December 31, 2022, respectively.

Collective Bargaining Agreements and Multiemployer Plans. As discussed in Note 10 - Other Retirement Plans, certain of MasTec’s subsidiaries are party to various collective bargaining agreements with unions representing certain of their employees, which require the Company to pay specified wages, provide certain benefits and contribute certain amounts to MEPPs. The Employee Retirement Income Security Act of 1974, as amended by the Multiemployer Pension Plan Amendments Act of 1980 (collectively, “ERISA”), which governs U.S.-registered MEPPs, subjects employers to substantial liabilities in the event of an employer’s complete or partial withdrawal from, or upon termination of, such plans.

The Company currently contributes, and in the past, has contributed to, plans that are underfunded, and, therefore, could have potential liability associated with a voluntary or involuntary withdrawal from, or termination of, these plans. As of June 30, 2023, the Company does not have plans to withdraw from, and is not aware of circumstances that would reasonably lead to material claims against it, in connection with the MEPPs in which it participates. There can be no assurance, however, that the Company will not be assessed liabilities in the future, including in the form of a surcharge on future benefit contributions or increased contributions on underfunded plans. The amount the Company could be obligated to pay or contribute in the future cannot be estimated, as these amounts are based on future levels of work of the union employees covered by these plans, investment returns, which could be negatively affected by economic and market conditions, and the level of underfunding of such plans. In connection with the IEA acquisition, the Company assumed a multiemployer pension plan withdrawal liability, under which IEA is currently obligated to make monthly payments of approximately $10,000. As of both June 30, 2023 and December 31, 2022, the remaining obligation approximated $1.9 million.

Indemnities. The Company generally indemnifies its customers for the services it provides under its contracts, as well as other specified liabilities, which may subject the Company to indemnity claims, liabilities and related litigation. As of June 30, 2023 and December 31, 2022, the Company had accrued project close-out liabilities of approximately $20 million and $40 million, respectively. The Company is not aware of any other material asserted or unasserted claims in connection with its potential indemnity obligations.

Other Guarantees. From time to time in the ordinary course of its business, MasTec guarantees the obligations of its subsidiaries, including obligations under certain contracts with customers, certain lease obligations, and in some states, obligations in connection with obtaining

contractors’ licenses. MasTec has also issued performance and other guarantees in connection with certain of its equity investments. MasTec also generally warrants the work it performs following substantial completion of a project. Much of the work performed by the Company is evaluated for defects shortly after the work is completed. If warranty claims occur, the Company could be required to repair or replace warrantied items, or, if customers elect to repair or replace the warrantied item using the services of another provider, the Company could be required to pay for the cost of the repair or replacement. Warranty claims have historically not been material.

Concentrations of Risk. The Company had approximately 1,305 customers for the six month period ended June 30, 2023. No customer represented greater than 10% of the Company’s consolidated net accounts receivable position, which is calculated as accounts receivable, net, less deferred revenue, as of either June 30, 2023 or December 31, 2022. For the three month periods ended June 30, 2023 and 2022, the Company derived approximately 35% and 42%, respectively, of its revenue from its top ten customers, and derived 36% and 43% for the six month periods ended June 30, 2023 and 2022, respectively.

Mas has a minority interest, and of which a member of management of a MasTec subsidiary owns the remaining interest. For the three month periods ended June 30, 2023 and 2022, revenue recognized by MasTec under this arrangement totaled approximately $36.1 million and $31.9 million, respectively, and totaled approximately $77.9 million and $60.7 million, respectively, for the six month periods ended June 30, 2023 and 2022. As of June 30, 2023 and December 31, 2022, related amounts receivable totaled approximately $50.4 million and $42.0 million, respectively. MasTec pays a management fee to this entity in connection with the subcontracting arrangement, under which MasTec incurred approximately $0.7 million and $0.5 million for the three month periods ended June 30, 2023 and 2022, respectively, and totaled approximately $1.2 million and $0.7 million, respectively, for the six month periods ended June 30, 2023 and 2022. As of June 30, 2023 and December 31, 2022, related amounts payable totaled approximately $0.1 million and $0.3 million, respectively.

From time to time, the Company advances amounts to the former owners of acquired businesses, which, under the provisions of the related purchase agreements, the former owners are obligated to repay. The Company made no advances for the three month period ended June 30, 2023, and for the three month period ended June 30, 2022, such advances totaled approximately $0.1 million. For the six month periods ended June 30, 2023 and 2022, such advances totaled approximately $0.1 million and $1.4 million, respectively. Amounts receivable for such advances totaled approximately $2.1 million and $2.0 million as of June 30, 2023 and December 31, 2022, respectively. In addition, the Company has a subcontracting arrangement with an entity in which it has a 25% interest. The Company’s interest in this entity is accounted for as an equity method investment. For both the three and six month periods ended June 30, 2023, the Company made equity contributions of approximately $3.6 million to this entity, of which $0.2 million was paid in cash. The Company made no equity contributions for the three month period ended June 30, 2022, and for the six month period ended June 30, 2022 equity contributions totaled approximately $0.5 million. As of June 30, 2023 and December 31, 2022,

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following is a discussion and analysis of our business, financial condition and results of operations as of and for the three and six month periods ended June 30, 2023 and 2022. This discussion and analysis should be read in conjunction with our consolidated financial statements and notes thereto in Item 1 of this Quarterly Report on Form 10-Q (this “Form 10-Q”), and the audited consolidated financial statements, accompanying notes and Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) contained in our 2022 Form 10-K. In this MD&A, “$” means U.S. dollars unless specified otherwise.

General Economic, Market and Regulatory Conditions

We have experienced, and may continue to experience, direct and indirect negative effects on our business and operations from negative economic, market and regulatory conditions, including permitting issues, market interest rates, inflationary effects on fuel prices, labor and materials costs, supply chain disruptions and uncertainty from potential market volatility that could adversely affect demand for future projects, delay existing project timing and/or cause increased project costs. We expect the remainder of 2023 to continue to be a dynamic macroeconomic environment, with elevated market interest rates and continuing, but moderating levels of cost inflation, any or all of which could adversely affect our costs and customer demand. These conditions could affect the cost of capital of both us and our customers, as well as our customers’ plans for capital investments and ongoing maintenance expenditures, which could negatively affect demand for our services. The extent to which general economic, market and regulatory conditions could affect our business, operations and financial results is uncertain as it will depend upon numerous evolving factors that we may neither be able to accurately predict nor quantify with specificity.

We believe that our financial position, cash flows and operational strengths will enable us to manage the current uncertainties resulting from general economic, market and regulatory conditions. We carefully manage our liquidity and monitor any potential effects from changing economic, market and regulatory conditions on our financial results, cash flows and/or working capital and will take appropriate actions in efforts to mitigate any impacts.

Business Overview

We are a leading infrastructure construction company operating mainly throughout North America across a range of industries. Our primary activities include the engineering, building, installation, maintenance and upgrade of communications, energy, utility and other infrastructure, such as: power delivery services, including transmission, distribution, environmental planning and compliance; wireless, wireline/fiber and customer fulfillment activities; power generation, primarily from clean energy and renewable sources; pipeline distribution infrastructure, including natural gas, carbon capture sequestration, water and pipeline integrity services; heavy civil; industrial infrastructure; and environmental remediation services. Our customers are primarily in these industries. Including our predecessor companies, we have been in business for over 90 years. For the twelve month period ended June 30, 2023, we had an average of approximately 810 locations and 32,000 employees, respectively, and as of June 30, 2023, we had approximately 860 locations and 33,000 employees, respectively. We offer our services under the MasTec® and other service marks and are ranked among the Top 400 Contractors by Engineering News-Record.

We provide our services to a diversified base of customers and a significant portion of our services are provided under master service and other service agreements, which are generally multi-year agreements. The remainder of our work is generated pursuant to contracts for specific projects or jobs that require the construction or installation of an entire infrastructure system or specified units within an infrastructure system.

We manage our operations under five operating segments, which represent our five reportable segments: (1) Communications; (2) Clean Energy and Infrastructure; (3) Oil and Gas; (4) Power Delivery; and (5) Other. This structure is generally focused on broad end-user markets for our labor-based construction services. See Note 13 - Segments and Related Information and Note 14 - Commitments and Contingencies in the notes to the consolidated financial statements, which are incorporated by reference, for additional information regarding our segment reporting and significant customer concentrations.

Backlog

Estimated backlog represents the amount of revenue we expect to realize over the next 18 months from future work on uncompleted construction contracts, including new contracts under which work has not begun, as well as revenue from change orders and renewal options. Our estimated backlog also includes amounts under master service and other service agreements and our proportionate share of estimated revenue from proportionately consolidated non-controlled contractual joint ventures. Estimated backlog for work under master service and other service agreements is determined based on historical trends, anticipated seasonal impacts, experience from similar projects and estimates of customer demand based on communications with our customers. Based on current expectations of our customers’ requirements, we anticipate that we will realize approximately 47% of our estimated June 30, 2023 backlog in 2023. The following table presents 18-month estimated backlog by reportable segment as of the dates indicated:


Reportable Segment (in millions):	June 30, 2023		March 31, 2023		June 30, 2022
Communications	$	5,420	$	5,602	$	5,031
Clean Energy and Infrastructure	3,324		3,546		1,896
Oil and Gas	2,042		2,013		1,456
Power Delivery	2,656		2,731		2,622
Other	—		—		—
Estimated 18-month backlog	$	13,442	$	13,892	$	11,005

As of June 30, 2023, 54% of our backlog is estimated to be attributable to amounts under master service or other service agreements, pursuant to which our customers are not contractually committed to purchase a minimum amount of services. Most of these agreements can be canceled on short or no advance notice. Timing of revenue for construction and installation projects included in our backlog can be subject to change as a result of customer, regulatory or other delays or cancellations, including from economic or other conditions, supply chain disruptions, inflationary effects, potential market uncertainty, permitting delays, climate-related matters, political unrest, such as military conflicts, effects of public health matters and/or other project-related factors. These effects, among others, could cause estimated revenue to be realized in periods later than originally expected, or not at all. We occasionally experience postponements, cancellations and reductions in expected future work due to changes in our customers’ spending plans, market volatility, changes in governmental permitting, regulatory delays and/or other factors. There can be no assurance as to our customers’ requirements or that actual results will be consistent with the estimates included in our forecasts. As a result, our backlog as of any particular date is an uncertain indicator of future revenue and earnings.

Backlog is a common measurement used in our industry. Our methodology for determining backlog may not, however, be comparable to the methodologies used by others. Backlog differs from the amount of our remaining performance obligations, which are described in Note 1 - Business, Basis of Presentation and Significant Accounting Policies in the notes to the consolidated financial statements, which is incorporated by reference. As of June 30, 2023, total 18-month backlog differed from the amount of our remaining performance obligations due primarily to the inclusion of $7.5 billion of estimated future revenue under master service and other service agreements within our backlog estimates, as described above, and the exclusion of approximately $2.1 billion of remaining performance obligations and estimated future revenue under master service and other service agreements in excess of 18 months, which amount is not included in the backlog estimates above. Backlog expected to be realized in 2023 differs from the amount of remaining performance obligations expected to be recognized for the same period due primarily to the inclusion of approximately $1.8 billion of estimated future revenue under master service and other service agreements that is included within the related backlog estimate.

Economic, Industry and Market Factors

We closely monitor the effects of changes in economic, industry and market conditions on our customers, including the potential effects of market conditions, including interest rates, inflation or other macroeconomic factors, as well as regulatory and climate-related matters. Changes in general economic and market conditions can affect demand for our customers’ products and services, which can increase or decrease our customers’ planned capital and maintenance budgets in certain end-markets. Market, regulatory and industry factors could affect demand for our services, or the cost to provide such services, including (i) changes to our customers’ capital spending plans, including any potential effects from market interest rates or levels of inflation, market uncertainty and/or volatility, supply chain issues and/or public health matters; (ii) new or changing regulatory requirements, governmental policy changes, and/or customer or industry initiatives, including with respect to climate change, environmental or sustainability matters and/or from changes in governmental permitting; (iii) economic, political or other market developments or uncertainty, including access to capital for customers in the industries we serve and/or political unrest, including military conflicts; (iv) changes in technology, tax and other incentives; and (v) mergers, acquisitions or other business transactions among the customers we serve.

Changes in demand and fluctuations in market prices for energy sources, including oil and gas products, can affect demand for our services. In particular, such changes can affect the level of activity in energy generation projects, including from renewable energy sources, as well as pipeline construction and carbon capture projects. The availability of transportation and transmission capacity can also affect demand for our services, including energy generation, electric grid and pipeline construction projects. These factors, as well as the highly competitive nature of our industry, can result in changes in levels of activity, project mix, and/or the profitability of the services we provide. In the face of increased pricing pressure or other market developments, we strive to maintain our profit margins through productivity improvements, cost reduction programs and/or business streamlining efforts. Market developments, including inflationary effects on fuel, labor and materials costs, and rising market interest rates, have had, and could continue to have, a negative effect on our profitability, to the extent that we have not been, and in the future are not able, to pass these costs through to our customers. While we actively monitor economic, industry and market factors that could affect our business, we cannot predict the effect that changes in such factors could have on our future results of operations, liquidity and cash flows, and we may be unable to fully mitigate, or benefit from, such changes.

Effect of Seasonality and Cyclical Nature of Business

Our revenue and results of operations are cyclical and can be subject to seasonal and other variations. For additional information regarding the effects of seasonality and the cyclical nature of our business, see Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in our 2022 Form 10-K.

Critical Accounting Estimates

This discussion and analysis of our financial condition and results of operations is based upon our consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of our consolidated financial statements requires the use of estimates and assumptions that affect the amounts reported in our consolidated financial statements and accompanying notes. A summary of our critical accounting estimates is included in Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in our 2022 Form 10-K. We are required to make estimates and judgments in the preparation of our financial statements that affect the reported amounts of assets and liabilities, revenues and expenses and related disclosures. We continually review these estimates and their underlying assumptions to ensure they are appropriate for the circumstances. Changes in the estimates and assumptions we use could have a material impact on our financial results. During the three and six months period ended June 30, 2023, there were no material changes in our critical accounting estimates or policies.

For details of our second quarter 2023 quarterly review for indicators of impairment, refer to Note 3 - Acquisitions, Goodwill and Other Intangible Assets, Net, in the notes to the consolidated financial statements, which is incorporated by reference.

Results of Operations

Comparison of Quarterly Results

The following table, which may contain slight summation differences due to rounding, reflects our consolidated results of operations in dollar and percentage of revenue terms for the periods indicated (dollar amounts in millions). Our consolidated results of operations are not necessarily comparable from period to period due to the effect of recent acquisitions and certain other items, which are described in the comparison of results section below. In this discussion, “acquisition” results are defined as results from acquired businesses for the first twelve months following the dates of the respective acquisitions, with the balance of results for a particular item attributed to “organic” activity.

EBITDA for our Power Delivery segment was $105 million, or 7.4% of revenue, for the six month period ended June 30, 2023, as compared with EBITDA of $88 million, or 6.7% of revenue, for the same period in 2022, an increase in EBITDA of approximately $17 million, or 19%. As a percentage of revenue, EBITDA increased by approximately 70 basis points, or $9 million, due primarily to improved project efficiencies, project mix and a reduction of approximately $12 million in acquisition and integration costs, offset, in part, by the effects of inflation on labor, fuel and materials costs. Higher levels of revenue contributed an increase in EBITDA of $8 million.

Other Segment. EBITDA from Other businesses totaled approximately $14 million for both the six month periods ended June 30, 2023 and 2022. EBITDA from Other businesses relates primarily to equity in earnings from our investments in the Waha JVs, offset, in part, by losses from other businesses and investments.

Corporate. Corporate EBITDA was negative $90 million for the six month period ended June 30, 2023, as compared with EBITDA of negative $85 million for the same period in 2022, for a decrease in EBITDA of approximately $5 million. Acquisition and integration costs included within general and administrative expenses decreased to $3 million for the six month period ended June 30, 2023 from $7 million for the same period in 2022. For the six month period ended June 30, 2023, Corporate EBITDA included approximately $2 million of income, net, from changes to estimated Earn-out accruals, $3 million of income from the final settlement and expiration of certain warrants related to the acquisition of IEA, and $5 million of expense from changes in the fair value of additional contingent payments to the former owners of an acquired business. For the six month period ended June 30, 2022, Corporate EBITDA included approximately $1 million of income, net, from changes to estimated Earn-out accruals and $4 million of income from changes in the fair value of additional contingent payments to the former owners of an acquired business, offset by approximately $7 million of expense from changes in the fair value of certain investments, net of income from strategic arrangements. For the six month period ended June 30, 2023, Corporate expenses not related to the above-described items increased by approximately $11 million as compared with the same period in the prior year, due primarily to increases in compensation expense and professional fees, as well as the effects of timing of ordinary course legal and other settlement matters.

Foreign Operations

Our foreign operations are primarily in Canada and, to a far lesser extent, in Mexico, the Caribbean and India. See Note 13 - Segments and Related Information in the notes to the consolidated financial statements, which is incorporated by reference.

Non-U.S. GAAP Financial Measures

As appropriate, we supplement our reported U.S. GAAP financial information with certain non-U.S. GAAP financial measures, including earnings before interest, income taxes, depreciation and amortization (“EBITDA”), adjusted EBITDA (“Adjusted EBITDA”), adjusted net income (“Adjusted Net Income”) and adjusted diluted earnings per share (“Adjusted Diluted Earnings Per Share”). These “adjusted” non-U.S. GAAP measures exclude, as applicable to the particular periods, non-cash stock-based compensation expense; acquisition and integration costs related to our recent acquisitions; fair value gains or losses, net, on an investment; and the bargain purchase gain from a 2021 acquisition; and, for Adjusted Net Income and Adjusted Diluted Earnings Per Share, amortization of intangible assets, and the tax effects of the adjusted items. These definitions of EBITDA and Adjusted EBITDA are not the same as in our Credit Facility or in the indenture governing our senior notes; therefore, EBITDA and Adjusted EBITDA as presented in this discussion should not be used for purposes of determining our compliance with the covenants contained in our debt instruments.

We use EBITDA and Adjusted EBITDA, as well as Adjusted Net Income and Adjusted Diluted Earnings Per Share to evaluate our performance, both internally and as compared with our peers, because these measures exclude certain items that may not be indicative of our core operating results, as well as items that can vary widely across different industries or among companies within the same industry. We believe that these adjusted measures provide a baseline for analyzing trends in our underlying business. Non-cash stock-based compensation expense can be subject to volatility from changes in the market price per share of our common stock or variations in the value and number of shares granted, and amortization of intangible assets is subject to acquisition activity, which varies from period to period. In 2021, we initiated a significant

transformation of our end-market business operations to position the Company for expected future opportunities. This transformation included significant acquisition activity to expand our scale and capacity in renewable energy, power delivery, heavy civil and telecommunications services, and has resulted in significant acquisition and integration costs. Beginning in the fourth quarter of 2021, due to the extent of the acquisition costs related to this acquisition activity and the extent of the integration efforts that have been, and continue to be, required in connection with such acquisitions, we are excluding acquisition and integration costs in calculating Adjusted EBITDA and Adjusted Net Income for these acquisitions.

In addition, since the second quarter of 2022, we exclude fair value gains or losses, net, for our investment in American Virtual Cloud Technologies, Inc. (“AVCT”) in calculating our adjusted results, with prior periods updated to conform to this presentation. We believe that fair value gains or losses for our investment in AVCT, a company in which we had no active involvement and which varied from period to period based on fluctuations in the market price of the investment, are not indicative of our core operations, and that this presentation improves comparability of our results with those of our peers. AVCT filed for bankruptcy in the first quarter of 2023, and our investment was fully written off. We exclude intangible asset amortization and selected purchase accounting adjustments, including the bargain purchase gain from a 2021 acquisition, from our adjusted measures due to their non-operational nature and inherent volatility, as acquisition activity varies from period to period. Note that while intangible asset amortization related to the assets of acquired entities is excluded from our non-U.S. GAAP financial measures, our non-U.S. GAAP financial measures include the revenue and all other expenses of the acquired entities, unless otherwise stated. We also believe that this presentation is common practice in our industry and improves comparability of our results with those of our peers. Each company’s definitions of these adjusted measures may vary as they are not standardized and should be used in light of the provided reconciliations.

We believe that these non-U.S. GAAP financial measures provide meaningful information and help investors understand our financial results and assess our prospects for future performance. Because non-U.S. GAAP financial measures are not standardized, it may not be possible to compare these financial measures with other companies’ non-U.S. GAAP financial measures having the same or similar names. These financial measures should not be considered in isolation from, as substitutes for, or alternative measures of, reported net income or diluted earnings per share, and should be viewed in conjunction with the most comparable U.S. GAAP financial measures and the provided reconciliations thereto. We believe these non-U.S. GAAP financial measures, when viewed together with our U.S. GAAP results and related reconciliations, provide a more complete understanding of our business. We strongly encourage investors to review our consolidated financial statements and publicly filed reports in their entirety and not rely on any single financial measure.

The following table presents a reconciliation of net income to EBITDA and Adjusted EBITDA in dollar and percentage of revenue terms, for the periods indicated. The tables below (dollar amounts in millions) may contain slight summation differences due to rounding.

(a) Represents the tax effects of the adjusted items that are subject to tax, including the tax effects of non-cash stock-based compensation expense, including from share-based payment awards. Tax effects are determined based on the tax treatment of the related item, the incremental statutory tax rate of the jurisdictions pertaining to the adjustment, and their effects on pre-tax income. For the three and six month periods ended June 30, 2023, our consolidated effective tax rates, as reported, were 14.9% and 39.6%, respectively, and as adjusted, were 23.9% and 18.9%, respectively. For the three and six month periods ended June 30, 2022, our consolidated effective tax rates, as reported, were 10.9% and 37.4%, respectively, and as adjusted, were 22.5% and 22.4%, respectively.

Financial Condition, Liquidity and Capital Resources

Our primary sources of liquidity are cash flows from operations, availability under our Credit Facility and our cash balances. Our primary liquidity needs are for working capital, capital expenditures, insurance and performance collateral in the form of cash and letters of credit, debt service, income taxes, earn-out obligations and equity and other investment funding requirements. We also evaluate opportunities for strategic acquisitions, investments and other arrangements from time to time, and we may consider opportunities to borrow additional funds, which may include borrowings under our Credit Facility or debt issuances, or to refinance, extend the terms of our existing indebtedness or retire outstanding debt, or to repurchase additional shares of our outstanding common stock under share repurchase authorizations, any of which may require our use of cash.

Capital Expenditures. For the six month period ended June 30, 2023, we spent approximately $119 million on capital expenditures, or $76 million, net of asset disposals, and incurred approximately $84 million of equipment purchases under finance leases and other financing arrangements. We estimate that we will spend approximately $175 million on capital expenditures, or approximately $100 million, net of asset disposals, in 2023, and we expect to incur approximately $150 million of equipment purchases under finance leases and other financing arrangements. Actual capital expenditures may increase or decrease in the future depending upon business activity levels, as well as ongoing assessments of equipment lease versus purchase decisions based on short and long-term equipment requirements.

Acquisitions and Earn-Out Liabilities. We typically utilize cash for business acquisitions and other strategic arrangements, and for the six month period ended June 30, 2023, we used $64 million of cash for this purpose. In addition, in most of our acquisitions, we have agreed to make future payments to the sellers that are contingent upon the future earnings performance of the acquired businesses, which we also refer to as “Earn-out” payments. Earn-out payments may be paid in cash or, under specific circumstances, MasTec common stock, or a combination thereof, generally at our option. The estimated total value of future Earn-out liabilities as of June 30, 2023 was approximately $99 million. Of this amount, approximately $16 million represents the liability for earned amounts. The remainder is management’s estimate of Earn-out liabilities that are contingent upon future performance. For the six month periods ended June 30, 2023 and 2022, we made $26 million and $27 million, respectively, of payments for Earn-outs.

Our acquisition of HMG provides for certain additional payments to be made to the sellers if certain acquired receivables are collected, which we refer to as the “Additional Payments.” Pursuant to the terms of the HMG purchase agreement, a portion of the Additional Payments will be made in cash, with the remainder due in shares of MasTec common stock. An Additional Payment of approximately $29.4 million was made in May 2022, which payment was composed of approximately $18 million in cash and 133,157 shares of MasTec common stock. As of June 30, 2023, the estimated fair value of remaining Additional Payments was approximately $40 million, which, for the six month period ended June 30, 2023, includes the effect of unrealized fair value losses related to the contingent shares of approximately $5 million and a reduction of approximately $2 million in the estimated remaining liability from changes in collections attributed to acquired balances. The number of shares that would be paid in connection with the remaining Additional Payments as of June 30, 2023 is approximately 160,000 shares. In addition, for the six month period ended June 30, 2023, a fair value gain of approximately $3 million was recognized related primarily to the remaining unexercised IEA warrants that expired on March 26, 2023.

Income Taxes. For the six month periods ended June 30, 2023 and 2022, tax payments, net of tax refunds totaled approximately $14 million and $1 million, respectively. Our tax payments vary with changes in taxable income and earnings based on estimates of full year taxable income activity and estimated tax rates.

Working Capital. We need working capital to support seasonal variations in our business, primarily due to the effect of weather conditions on external construction and maintenance work and the spending patterns of our customers, both of which influence the timing of associated

spending to support related customer demand. Working capital needs are generally higher during the summer and fall months due to increased demand for our services when favorable weather conditions exist in many of the regions in which we operate. Conversely, working capital needs are typically converted to cash during the winter months. These seasonal trends, however, can be offset by changes in the timing of projects, which can be affected by project delays or accelerations and/or other factors that may affect customer spending.

Working capital requirements also tend to increase when we commence multiple projects or particularly large projects because labor, including subcontractor costs, and certain other costs, including inventory, typically become payable before the receivables resulting from work performed are collected. The timing of billings and project close-outs can also contribute to changes in unbilled revenue. As of June 30, 2023, we expect that substantially all of our unbilled receivables will be billed to customers in the normal course of business within the next twelve months. Total accounts receivable, which consists of contract billings, unbilled receivables and retainage, net of allowance, increased to approximately $3.3 billion as of June 30, 2023 from $3.1 billion as of December 31, 2022 due, in part, to timing of project billings and collections. See below for discussion of our days sales outstanding, net of contract liabilities, which we refer to as days sales outstanding, or “DSO.”

Our payment billing terms are generally net 30 days, and some of our contracts allow our customers to retain a portion of the contract amount (generally, from 5% to 10% of billings) until the job is completed. As part of our ongoing working capital management practices, we evaluate opportunities to improve our working capital cycle time through contractual provisions and certain financing arrangements. For certain customers, we maintain inventory to meet the materials requirements of the contracts. Occasionally, certain of our customers pay us in advance for a portion of the materials we purchase for their projects or allow us to pre-bill them for materials purchases up to specified amounts. Vendor terms are generally 30 days. Our agreements with subcontractors often contain a “pay-if-paid” provision, whereby our payments to subcontractors are made only after we are paid by our customers.

Summary of Financial Condition, Liquidity and Capital Resources

Including our current assessment of general economic conditions on our results of operations and capital resource requirements, we anticipate that funds generated from operations, borrowings under our credit facilities and our cash balances will be sufficient to meet our working capital requirements, anticipated capital expenditures, debt service obligations, insurance and performance collateral requirements, letter of credit needs, earn-out obligations, required income tax payments, acquisition, strategic arrangement and investment funding requirements, share repurchase activity and other liquidity needs for the next twelve months and the foreseeable future.

Sources and Uses of Cash

As of June 30, 2023, we had approximately $1,388 million in working capital, defined as current assets less current liabilities, as compared with $1,363 million as of December 31, 2022, an increase of approximately $25 million. Cash and cash equivalents totaled approximately $120 million and $371 million as of June 30, 2023 and December 31, 2022, respectively, for a decrease of approximately $251 million. See discussion below for further detail regarding our cash flows.

Sources and uses of cash are summarized below (in millions):


	For the Six Months Ended June 30,
	2023		2022
Net cash (used in) provided by operating activities	$	(97.9)	$	1.5
Net cash used in investing activities	$	(141.5)	$	(220.0)
Net cash used in financing activities	$	(12.2)	$	(3.0)

Operating Activities. Cash flow from operations is primarily influenced by changes in the timing of demand for our services and operating margins, but can also be affected by working capital needs associated with the various types of services we provide. Working capital is affected by changes in total accounts receivable, prepaid expenses and other current assets, accounts payable and payroll tax payments, accrued expenses and contract liabilities, all of which tend to be related. These working capital items are affected by changes in revenue resulting from the timing and volume of work performed, variability in the timing of customer billings and collections of receivables, as well as settlement of payables and other obligations. Net cash used in operating activities for the six month period ended June 30, 2023 was $98 million, as compared with approximately $2 million of net cash provided by operating activities for the same period in 2022, for a decrease in net cash provided by operating activities of approximately $99 million, due to an increase in net loss, as well as the effect of timing-related changes in working capital-related assets and liabilities, net, including a reduction in accounts payable and accrued expenses and an increase in contract assets due to ordinary course project activity, offset, in part, by a net increase in expenses that reconcile net income to operating cash flows, including depreciation and amortization of intangible assets.

DSO is calculated as total accounts receivable, net of allowance, less contract liabilities, divided by average daily revenue for the most recently completed quarter as of the balance sheet date. Our days sales outstanding, net of contract liabilities (“DSO”), was 90 as of June 30, 2023, and as of December 31, 2022, was 83. Our DSOs can fluctuate from period to period due to timing of billings, billing terms, collections and settlements, timing of project close-outs and retainage collections, changes in project and customer mix and the effect of working capital initiatives. The increase in DSO as of June 30, 2023 as compared with December 31, 2022 was due to timing of ordinary course billing and collection activities. Other than ordinary course matters subject to litigation, we do not anticipate material collection issues related to our outstanding accounts receivable balances, nor do we believe that we have material amounts due from customers experiencing financial difficulties. Based on current information, we expect to collect substantially all of our outstanding accounts receivable balances within the next twelve months.

Investing Activities. Net cash used in investing activities decreased by approximately $79 million to $141 million for the six month period ended June 30, 2023 from $220 million for the same period in 2022. Capital expenditures for the six month period ended June 30, 2023 totaled $119

million, or $76 million, net of asset disposals, as compared with $190 million, or $172 million, net of asset disposals, for the same period in 2022, for a decrease in cash used in investing activities of approximately $96 million, due to the effect in the prior year period of acceleration of capital expenditures to address supply chain disruption concerns. The decrease in cash used in investing activities from capital expenditure activity was offset, in part, by an increase in cash used in investing activities from acquisition activity. For the six month period ended June 30, 2023, we paid $64 million related to acquisitions, in which period we completed three acquisitions, as compared with $45 million for the same period in 2022, in which period we completed two acquisitions, for an increase of approximately $19 million of cash used in investing activities.

Financing Activities. Net cash used in financing activities for the six month period ended June 30, 2023 was $12 million, as compared with $3 million for the same period in 2022, for an increase in cash used in financing activities of $9 million. For the six month period ended June 30, 2023, we had $107 million of borrowings, net of repayments, under our credit facility and term loans, as compared with $214 million for the same period in 2022, for a decrease in cash provided by financing activities of approximately $107 million. Additionally, for the six month period ended June 30, 2023, we paid approximately $12 million to holders of our non-controlling interests, including $10 million to acquire the remaining 15% interests of one of these entities, whereas for the same period in 2022, we made no payments. The increase in cash used in financing activities from the above described items was offset, in part, by the effects of share repurchase activity, which totaled $81 million for the six month period ended June 30, 2022, whereas there were no share repurchases for the same period in 2023. Additionally, payments of acquisition-related contingent consideration included within financing activities totaled $9 million for the six month period ended June 30, 2023 as compared with $27 million for the same period in 2022, for a decrease in cash used in financing activities of $18 million. Total payments with respect to acquisition-related contingent consideration, including payments in excess of acquisition-date liabilities, which are classified within operating activities, totaled $26 million for the six month period ended June 30, 2023 as compared with $27 million for the same period in 2022. Additional Payments for acquisition-related contingent assets related to the acquisition of HMG totaled approximately $18 million for the six month period ended June 30, 2022, whereas for the same period in 2023, we made no payments.

Senior Credit Facility

We have a senior unsecured credit facility (the “Credit Facility”) that matures on November 1, 2026 and has aggregate borrowing commitments totaling $2.25 billion, which amount is composed of $1.9 billion of revolving commitments and a Term Loan totaling $350 million in original principal amount. Aggregate outstanding borrowings under the Credit Facility as of June 30, 2023 totaled approximately $1.4 billion. Borrowings under the Credit Facility are used for working capital requirements, capital expenditures and other corporate purposes, including potential acquisitions, equity investments or other strategic arrangements, and/or the repurchase or prepayment of indebtedness, among other corporate borrowing requirements, including potential share repurchases.

We are dependent upon borrowings and letters of credit under our Credit Facility to fund our operations. Should we be unable to comply with the terms and conditions of our Credit Facility, we would be required to obtain modifications to the Credit Facility or obtain an alternative source of financing to continue to operate, neither of which may be available to us on commercially reasonable terms, or at all. The Credit Facility is subject to certain provisions and covenants, as more fully described in Note 7 - Debt in the notes to the audited consolidated financial statements included in our 2022 Form 10-K.

4.50% Senior Notes

We have $600 million aggregate principal amount of 4.50% Senior Notes due August 15, 2028 (the “4.50% Senior Notes”). The 4.50% Senior Notes are subject to certain provisions and covenants, as more fully described in Note 7 - Debt in the notes to the audited consolidated financial statements included in our 2022 Form 10-K.

6.625% Senior Notes

We have $300 million aggregate principal amount of 6.625% Senior Notes due August 15, 2029, which amount is composed of $225.1 million aggregate principal amount of 6.625%% IEA senior notes (the “6.625% IEA Senior Notes”) and $74.9 million aggregate principal amount of 6.625% MasTec senior notes (the “6.625% MasTec Senior Notes”). The 6.625% IEA Senior Notes are structurally subordinated to all indebtedness and other liabilities, including trade payables, of the Company’s subsidiaries and are effectively subordinated to any secured indebtedness of IEA Energy Services LLC, the issuer of the IEA 6.625% Senior Notes, to the extent of the value of the collateral securing such indebtedness. The 6.625% MasTec Senior Notes are general senior unsecured obligations of the Company, and rank equal in right of payment with all of the Company’s existing and future senior unsecured indebtedness and senior in right of payment to any of the Company’s future subordinated indebtedness. The 6.625% MasTec Senior Notes are effectively subordinated to all secured indebtedness of the Company to the extent of the value of the assets securing such indebtedness, and are structurally subordinated to all obligations of the subsidiaries of the Company, including trade payables and the 6.625% IEA Senior Notes. The 6.625% Senior Notes are subject to certain provisions and covenants, as more fully described in Note 7 - Debt in the notes to the audited consolidated financial statements included in our 2022 Form 10-K.

2022 Term Loan Facility

We have $700.0 million of unsecured term loans that were entered into in connection with the IEA acquisition, composed of $400.0 million in principal amount of three-year loans maturing on October 7, 2025, and $300.0 million in principal amount of five-year loans maturing on October 7, 2027 (together, the “2022 Term Loan Facility”). The obligations under the 2022 Term Loan Facility are unsecured and are not guaranteed by any of the Company or its subsidiaries. The 2022 Term Loan Facility is subject to certain provisions and covenants, as more fully described in Note 7 - Debt in the notes to the audited consolidated financial statements included in our 2022 Form 10-K.

Debt Covenants

We were in compliance with the provisions and covenants contained in our outstanding debt instruments as of June 30, 2023.

Additional Information

For detailed discussion and additional information pertaining to our debt instruments, see Note 7 - Debt in the notes to the audited consolidated financial statements included in our 2022 Form 10-K. Also, see Note 7 - Debt in the notes to the consolidated financial statements in this Form 10-Q, which is incorporated by reference, for current period balances and discussion.

Off-Balance Sheet Arrangements

As is common in our industry, we have entered into certain off-balance sheet arrangements in the ordinary course of business. Our significant off-balance sheet transactions include liabilities associated with non-cancelable operating leases with durations of less than twelve months, letter of credit obligations, surety and performance and payment bonds entered into in the normal course of business, self-insurance liabilities, liabilities associated with multiemployer pension plans, liabilities associated with potential funding obligations and indemnification and/or guarantee arrangements relating to our equity and other investment arrangements, including our variable interest entities. These off-balance sheet arrangements have not had, and are not reasonably likely to have, a material impact on our financial condition, revenues or expenses, results of operations, liquidity, cash requirements or capital resources in the next twelve months or in the foreseeable future. Refer to Note 14 - Commitments and Contingencies, Note 4 - Fair Value of Financial Instruments and Note 15 - Related Party Transactions in the notes to the consolidated financial statements, which are incorporated by reference.

Impact of Inflation

Over the past year, inflation, supply chain and labor constraints have had a significant impact on the global economy, including on the construction industry in the United States. We expect elevated market interest rates and continuing, but moderating levels of cost inflation for the remainder of 2023. The primary inflationary factors directly affecting our operations are labor, fuel and material costs. The current elevated levels of inflation have caused an increase in consumer prices and regulatory actions to increase interest rates, while the labor market remains at historically low levels of unemployment, creating further pressure on the supply of skilled labor. In times of low unemployment and/or high inflation, our labor costs may increase due to shortages in the supply of skilled labor and increases in compensation rates generally. Although most project materials are provided by our customers, increases in the cost of materials could negatively affect the economic viability of our customers’ projects, and accordingly, demand for our services. Material and commodity prices are subject to unexpected fluctuations due to events outside of our control, including fluctuations in global supply and demand, climate-related effects, and geopolitical events, including military conflicts, which events have recently caused market volatility. The recent elevation in levels of labor, fuel and materials costs, to the extent we have been unable to pass such increases along to our customers, has negatively affected our project margins, and could continue to affect our profitability in the future. Market volatility and/or uncertainty can also affect our customers’ investment decisions and subject us to project cancellations, deferrals or unexpected changes in the timing of project work. Market prices for goods can also be affected by supply chain disruptions. Additionally, as discussed within “Interest Rate Risk” below, the current inflationary environment has also resulted in an increase in market interest rates, which has increased the rates of interest on our variable rate debt, which rates may continue to increase depending on further monetary and fiscal actions taken to reduce inflation.

We closely monitor inflationary factors, including current rates of inflation, and any potential effects they may have on our business operations, operating results and/or financial condition. While the impact of these factors cannot be fully eliminated, we proactively work to mitigate their effects; however, inflationary pressures and interest rate increases could adversely affect our business operations in the future.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

As of June 30, 2023, our variable interest rate debt was primarily related to our Credit Facility and our term loans. Outstanding borrowings under our Credit Facility bear interest, at the Company’s option, at a rate equal to either (a) Term Secured Overnight Financing Rate (“SOFR”), as defined in the Credit Facility, plus a margin of 1.125% to 1.625%, or (b) a Base Rate, as defined in the Credit Facility, plus a margin of 0.125% to 0.625%. As of June 30, 2023, we had approximately $1 billion aggregate principal amount of outstanding revolving loans under our Credit Facility with a weighted average interest rate of 6.90% and a Term Loan with a balance of $346 million and an interest rate of 6.83% The current year interest rates for outstanding revolving loans under our Credit Facility and Term Loan reflect basis point increases of approximately 430 and 390, respectively, over the comparable period in 2022.

Outstanding loans under the $400 million Three-Year Tranche of our 2022 Term Loan Facility bear interest, at the Company’s option, at a rate equal to either (a) SOFR, as defined in the 2022 Term Loan Facility, plus a margin of 1.125% to 1.500%, or (b) a Base Rate, as defined in the 2022 Term Loan Facility, plus a margin of 0.125% to 0.500%. Outstanding loans under the $300 million Five-Year Tranche of our 2022 Term Loan Facility bear interest, at the Company’s option, at a rate equal to either (a) Term SOFR plus a margin of 1.250% to 1.625%, or (b) a Base Rate, plus a margin of 0.250% to 0.625%. As of June 30, 2023, the Three-Year Tranche and Five-Year Tranche term loans accrued interest at weighted average rates of 6.621% and 6.746%, respectively.

Our interest expense is affected by the overall interest rate environment. Our variable rate interest debt subjects us to risk from increases in prevailing interest rates. This risk has increased in the current market environment, in which the Federal Reserve has increased interest rates, resulting in an increase in our variable interest rates and related interest expense. We manage interest rate risk by maintaining a mix of fixed and variable rate debt obligations. An additional 100 basis point increase in the applicable interest rates under our Credit Facility and term loans would have increased our interest expense by approximately $11 million for the six month period ended June 30, 2023.

As of June 30, 2023, our fixed interest rate debt primarily included $600 million aggregate principal amount of 4.50% Senior Notes, $300 million aggregate principal amount of 6.625% Senior Notes and $368 million of finance lease obligations, which accrued interest at a weighted average interest rate of approximately 4.4%. None of this debt subjects us to interest rate risk, but we may be subject to changes in interest rates if and when we refinance this debt at maturity or otherwise.

Foreign Currency Risk

Certain of our consolidated revenue and operating expenses are in foreign currencies. Our foreign operations are primarily in Canada. Revenue generated from foreign operations represented 1% of our total revenue for the six month period ended June 30, 2023. Revenue and expense related to our foreign operations are, for the most part, denominated in the functional currency of the foreign operation, which minimizes the impact that fluctuations in exchange rates would have on net income or loss. We are, however, subject to fluctuations in foreign currency exchange rates when transactions are denominated in currencies other than the functional currencies and for our foreign operations with a functional currency other than the local currency. Such activity was not material to our operations for the six month period ended June 30, 2023. Translation gains or losses, which are recorded in other comprehensive income or loss, result from translation of the assets and liabilities of our foreign subsidiaries into U.S. dollars. For the six month period ended June 30, 2023, foreign currency translation gains, net, totaled approximately $2 million and related to our operations in Canada and Mexico.

Our exposure to fluctuations in foreign currency exchange rates could increase in the future if we continue to expand our operations outside of the United States. We seek to manage foreign currency exposure by minimizing our consolidated net asset and liability positions in currencies other than the functional currency, which exposure was not significant to our consolidated financial position as of June 30, 2023. We may enter into foreign currency derivative contracts in the future to manage such exposure.

Other Market Risk

As discussed in Note 4 - Fair Value of Financial Instruments in the notes to the consolidated financial statements, which is incorporated by reference, we have certain investments that may be subject to market risk and could be subject to volatility based on market conditions.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures. As of the end of the period covered by this Quarterly Report on Form 10-Q, our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)). We maintain disclosure controls and procedures designed to ensure that information required to be disclosed in reports filed or submitted by us under the Exchange Act is recorded, processed, summarized and reported within time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, or persons performing similar functions, as appropriate, to allow timely decisions regarding required disclosure. In conducting the evaluation of disclosure controls and procedures and internal control over financial reporting as of December 31, 2022, as described in the 2022 Form 10-K, we identified the following material weaknesses in our internal control over financial reporting:

•Design and operating effectiveness of controls over the order to cash cycle predominantly related to the assessment of certain 2021 acquired entities that underwent initial controls evaluation in 2022 (the “2021 Acquired Entities”).

•Operating effectiveness of controls related to the initial purchase price allocation of the 2022 IEA acquisition.

•Design of the precision level for a variance analysis management review control within the period end reporting cycle.

In addition, for certain 2021 Acquired Entities, we identified control deficiencies that, when aggregated, constitute material weaknesses as follows:

•Design and operating effectiveness of information technology general computer controls (“ITGCs”) in the areas of user access and program change-management for certain information technology systems (the “affected IT systems”) that are critical to capturing, processing, and reporting financial transactions. These ineffective information technology controls contributed to (i) improper segregation of duties among certain business process controls and (ii) ineffective data validation of spreadsheets and system-generated reports.

•Design and operating effectiveness of business process controls in each of the following business cycles: procure to pay, asset management, hire to pay, and period-end reporting.

As a result, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were not effective at the reasonable assurance level as of June 30, 2023.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.

Notwithstanding the material weaknesses in our internal control over financial reporting, the consolidated financial statements included in this Quarterly Report on Form 10-Q fairly present, in all material respects, our financial position, results of operations, and cash flows for the periods presented in conformity with accounting principles generally accepted in the United States of America. In addition, the material weaknesses did not result in any restatements of the Company’s audited or unaudited consolidated financial statements and disclosures for any prior period previously reported by the Company.

To the extent permitted under SEC guidance, the disclosure controls and procedures of two businesses in 2022, including IEA, and of one business acquired in 2023, were excluded from the evaluation of effectiveness of the Company’s disclosure controls and procedures as of June 30, 2023 due to the timing of the acquisitions. These three acquisitions’ total assets constituted approximately 20% of the Company’s total assets as of June 30, 2023, and represented approximately 18% of the Company’s revenue for the six month period then ended.

Management’s Plans for Remediation of Material Weaknesses. Management has implemented and continues to implement measures designed to ensure that control deficiencies contributing to the material weaknesses are remediated, such that these controls are designed,

implemented, and operating effectively. These remediation actions are ongoing and include or are expected to include the following actions, predominately at 2021 Acquired Entities: (i) expanding functions of IT compliance from the existing, effective ITGC environment at the enterprise level to the 2021 Acquired Entities; (ii) developing a training program addressing ITGCs and IT policies with appropriate IT personnel; (iii) implementing procedures to ensure enforcement of proper segregation of duties; (iv) enhancing IT management review and testing plans to monitor ITGCs and (v) adding resources and training programs addressing the design, implementation and documentary evidence requirements of control procedures over the order to cash, procure to pay, asset management, hire to pay, initial acquisition purchase price allocation and period-end reporting processes for appropriate personnel. We may take additional measures to remediate the underlying control deficiencies identified or modify the remediation plans described above. Although we believe that these actions will remediate the material weaknesses, the weaknesses will not be considered remediated until the applicable controls operate for a sufficient period of time and management has concluded, through testing, that these controls are operating effectively.

Changes in Internal Control Over Financial Reporting. There have been no changes in the Company’s internal control over financial reporting during the quarter ended June 30, 2023 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting other than remediation efforts related to the material weaknesses identified above.
