NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

March 31, 2026

(Unaudited)

2.			BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

Presentation Basis—The accompanying Condensed Consolidated Financial Statements are presented in accordance with accounting policies generally accepted in the United States (“GAAP”) and reflect all wholly owned subsidiaries and those entities the Company is required to consolidate. See Note 5 - 50% Owned Subsidiary and Note 6 - Construction Joint Ventures for further discussion of the Company’s consolidation policy for those entities that are not wholly owned. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, considered necessary for a fair presentation have been included. All significant intercompany accounts and transactions have been eliminated in consolidation. Reclassifications have been made to historical financial data in the Condensed Consolidated Financial Statements to conform to the current year presentation.

Estimates and Judgments—The preparation of the accompanying Condensed Consolidated Financial Statements in conformance with GAAP requires management to make estimates and judgments that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Certain accounting estimates of the Company require a higher degree of judgment than others in their application. These include the recognition of revenue and earnings from construction contracts over time, the valuation of long-lived assets, goodwill and purchase accounting estimates. Management continually evaluates all of its estimates and judgments based on available information and experience; however, actual results could differ from these estimates.

Significant Accounting Policies

Consistent with Regulation S-X Rule 10-01(a), the Company has omitted significant accounting policies in this quarterly report that would duplicate the disclosures contained in the Company’s annual report on Form 10-K for the year ended December 31, 2025 under “Part II, Item 8. Financial Statements and Supplementary Data - Notes to Consolidated Financial Statements.” This quarterly report should be read in conjunction with the Company’s most recent annual report on Form 10-K.

Accounts Receivable—Receivables are generally based on amounts billed to the customer in accordance with contractual provisions. Receivables are written off based on the individual credit evaluation and specific circumstances of the customer, when such treatment is warranted. The Company performs a review of outstanding receivables, historical collection information and existing economic conditions to determine if there are potential uncollectible receivables. At March 31, 2026 and December 31, 2025, our allowance for our estimate of expected credit losses was zero.

Contracts in Progress—For performance obligations satisfied over time, amounts are billed as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals (e.g., biweekly or monthly) or upon achievement of contractual milestones. Contract liabilities arise when the Company bills its customers prior to revenue recognition. Conversely, contract assets are generated when customer billing occurs subsequent to revenue recognition.

Many of the contracts under which the Company performs work also contain retainage provisions. Retainage refers to that portion of our billings held for payment by the customer pending satisfactory completion of the project. Unless reserved, the Company assumes that all amounts retained by customers under such provisions are fully collectible. At March 31, 2026 and December 31, 2025, contract assets included $59.1 million and $40.7 million of retainage, respectively, and contract liabilities included $158.7 million and $147.6 million of retainage, respectively. Retainage on active contracts is classified as current regardless of the term of the contract and is generally collected within one year of the completion of a contract. We anticipate collecting approximately 65% of our March 31, 2026 retainage during the next twelve months, and the balance thereafter. Retainage is reported on the Condensed Consolidated Balance Sheets within “Contract assets” and “Contract liabilities” on a contract-by-contract basis at the end of each reporting period.

Contract assets increased by $30.6 million compared to December 31, 2025, primarily due to higher unbilled revenue and an increase in retainage. Contract liabilities increased by $43.3 million compared to December 31, 2025, due to the timing of billings and work progression, partly offset by an increase in retainage. Revenue recognized for the three months ended March 31, 2026 that was included in the contract liability balance on December 31, 2025 was $312.7 million. Revenue recognized for the three months ended March 31, 2025 that was included in the contract liability balance on December 31, 2024 was $172.6 million.

Cash, Cash Equivalents and Restricted Cash—Our cash and cash equivalents are comprised of highly liquid investments with original maturities of three months or less. The Company maintains its cash and cash equivalents at major financial institutions. The cash and cash equivalents balance at one or more of these financial institutions exceeds the Federal Depository Insurance Corporation (“FDIC”) insurance coverage. The Company periodically assesses the credit risk associated with these financial institutions and believes that the risk of loss is minimal. There was no restricted cash included in the Condensed Consolidated Balance Sheets at March 31, 2026 and December 31, 2025, respectively.

New Accounting Pronouncements

In November 2024, the FASB issued ASU No. 2024-03, “Disaggregation of Income Statement Expenses” which requires companies to disclose disaggregated information for prescribed expense categories within relevant income statement expense line items. The guidance is effective for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the impact of adopting the standard and plans to adopt the provisions of ASU 2024-03 in fiscal year 2027. This ASU affects financial statement disclosure only, and its adoption will not affect our results of operations or financial position.


3.			ACQUISITIONS

CEC Acquisition

On September 1, 2025, Sterling acquired substantially all of the assets of Irving, Texas-based CEC Facilities Group, LLC, et al (“CEC”) (the “CEC Acquisition”). The integration of CEC, a leading specialty electrical and mechanical contractor, broadens Sterling's array of valuable E-Infrastructure services, extends the segment into the next critical phases of the project lifecycle, and creates significant opportunities to cross-sell services. The CEC Acquisition is accounted for using the acquisition method of accounting in accordance with ASC Topic 805, Business Combinations. The results of CEC since the date of acquisition are included within our E-Infrastructure Solutions segment.

Purchase Consideration—Sterling completed the CEC Acquisition for a purchase price of $561.6 million, net of cash acquired, detailed as follows:


(In thousands, except per share data)
Cash consideration transferred	$	442,937
Equity consideration transferred (285 thousand shares at $278.53 per share(1))	79,458
Earn-out (2)	39,194

Total fair value of consideration	$	561,589

(1) Sterling’s closing stock price on August 29, 2025.

(2) The earn-out arrangement requires the Company to pay up to $80 million based upon CEC’s achievement of certain operating income targets.

Preliminary Purchase Price Allocation—The aggregate purchase price noted above was allocated to the assets and liabilities acquired based upon their estimated fair values at the acquisition closing date, which were based, in part, upon a preliminary external appraisal and valuation of certain assets, including specifically identified intangible assets. The excess of the fair value of consideration over the preliminary estimated fair value of the net tangible and identifiable intangible assets acquired totaling $308.9 million was recorded as goodwill. This goodwill represents the value of expected future earnings and cash flows, as well as the synergies created by the integration of the new business within our organization, including cross-selling opportunities to help strengthen our existing service offerings and expand our market position. The goodwill and intangibles related to the acquisition are expected to be deductible for tax purposes.

The following table summarizes our preliminary purchase price allocation at the acquisition closing date, net of cash acquired:


(In thousands)
Net tangible assets:
Accounts receivable	$	73,549
Contract assets	40,632
Other current assets	20,117
Property and equipment, net	15,363

Other non-current assets, net	25,820
Accounts payable	(45,460)
Contract liabilities	(53,555)
Current portion of long-term lease obligations	(3,860)
Other current and non-current liabilities	(47,673)
Total net tangible assets	24,933
Identifiable intangible assets	227,800
Goodwill	308,856
Total fair value of consideration transferred	$	561,589

The purchase price allocation for the CEC Acquisition is preliminary. Amounts provisionally assigned to working capital, identifiable intangible assets, and certain other assets and liabilities are subject to change as we complete our valuation procedures. We expect to finalize the allocation as soon as practicable within the measurement period, which will not exceed one year from the acquisition date. Measurement‑period adjustments, if any, will be recorded in the period they are identified and may affect the amounts recognized for assets acquired, liabilities assumed, goodwill, and the intangible amortization in our results of operations.

Identifiable Intangible Assets—Intangible assets identified as part of the CEC Acquisition are reflected in the table below and are recorded at their estimated fair value, as determined by the Company’s management, based on available information which includes a preliminary valuation from external experts. The estimated useful lives for intangible assets were determined based upon the remaining useful economic lives of the intangible assets that are expected to contribute directly or indirectly to future cash flows.


(In thousands, except life data)	Weighted Average Life (Years)	September 1, 2025 Fair Value
Customer relationships (1)	25	$	156,300
Trade names (2)	25	71,500
Total		$	227,800

(1) The customer relationship intangible asset was valued using the multi‑period excess earnings method (MPEEM), an income‑based approach. This method estimates the present value of the future cash flows attributable to existing customers with consideration given to estimated customer attrition rates. Significant assumptions used in the valuation included projected revenues, operating margins, a customer attrition rate of 10%, and a discount rate reflecting the risk inherent in the projected cash flows of 13.5%.

(2) The trade name intangible asset was valued using the relief‑from‑royalty method. Significant assumptions used in the valuation included projected revenues, an estimated royalty rate of 1.5%, and a discount rate of 12.5%.

Supplemental Pro Forma Information (Unaudited)—The following unaudited pro forma combined financial information (“the pro forma financial information”) gives effect to the CEC Acquisition and related events as if they occurred at the beginning of the earliest comparative period and includes adjustments to (1) include additional intangible asset amortization associated with the CEC Acquisition (approximately $9.1 million annually), (2) include tax and interest impacts, and (3) include the pro forma results of CEC for the three months ended March 31, 2025. This pro forma financial information has been presented for illustrative purposes only and is not necessarily indicative of the operating results that would have been achieved had the pro forma events taken place on the dates indicated. Further, the pro forma financial information does not purport to project the future operating results of the combined company following the CEC Acquisition.


(In thousands)	Three Months Ended March 31, 2025

Pro forma revenue	$	518,405
Pro forma net income attributable to Sterling common stockholders	$	45,447


4.			REVENUE FROM CUSTOMERS

Remaining Performance Obligations (“RPOs”)—RPOs represent the aggregate amount of our contract transaction price related to performance obligations that are unsatisfied or partially satisfied at the end of the period. RPOs include the entire expected revenue values for joint ventures we consolidate and our proportionate value for those we proportionately consolidate. RPOs may not be indicative of future operating results. Projects included in RPOs may be canceled or modified by customers; however, the customer would be obligated to compensate the Company for work performed through the date of termination and for any applicable contractual costs for cancellations or modifications. Excluded from RPOs are potential orders under master service agreements and expected revenues under certain non-fixed price contracts. The following table presents the Company’s RPOs, by segment:


(In thousands)	March 31, 2026		December 31, 2025
E-Infrastructure Solutions RPOs	$	2,711,311	$	1,843,536
Transportation Solutions RPOs	1,035,124		1,124,429
Building Solutions RPOs - Commercial	49,319		42,977
Total RPOs	$	3,795,754	$	3,010,942

At March 31, 2026, the Company expects to recognize approximately 70% of its RPOs as revenue during the next 12 months, and substantially all of the remaining balance in the 12 to 24 months thereafter.

Revenue Disaggregation—The following tables present the Company’s revenue disaggregated by major end market and contract type:


(In thousands)	Three Months Ended March 31,
Revenues by major end market	2026		2025
E-Infrastructure Solutions Revenues	$	597,732	$	218,263

Residential and Other	91,964		80,199
Total Revenues	$	825,675	$	430,949

Variable Consideration

The Company has projects that it is in the process of negotiating, or awaiting final approval of, unapproved change orders and claims with its customers. The Company is proceeding with its contractual rights to recoup additional costs incurred from its customers based on completing work associated with change orders, including change orders with pending change order pricing, or claims related to significant changes in scope which resulted in substantial delays and additional costs in completing the work. Unapproved change order and claim information has been provided to the Company’s customers and negotiations with the customers are ongoing. If additional progress with an acceptable resolution is not reached, legal action will be taken. Based upon the Company’s review of the provisions of its contracts, specific costs incurred and other related evidence supporting the unapproved change orders and claims, together in some cases as necessary with the views of the Company’s outside claim consultants, the Company concluded it was appropriate to include in project price amounts of $2.9 million, at both March 31, 2026 and December 31, 2025, relating to unapproved change orders and claims. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined.

Contract Estimates

Accounting for long-term contracts and programs involves the use of various techniques to estimate total contract revenue and costs. For long-term contracts, the Company estimates the profit on a contract as the difference between the total estimated revenue and expected costs to complete a contract and recognizes such profit over the life of the contract. Contract estimates are based on various assumptions to project the outcome of future events that often span several years. These assumptions include labor productivity and availability, the complexity of the work to be performed, the cost and availability of materials and the performance of subcontractors. Changes in job performance, job conditions and estimated profitability, including those changes arising from contract penalty provisions and final contract settlements, may result in changes in revenue and are recognized in the period in which the changes are determined. Changes in contract estimates on performance obligations satisfied or partially satisfied in previous periods resulted in net revenue increases of $55.8 million and $30.5 million for the three months ended March 31, 2026 and 2025, respectively.


5.			50% OWNED SUBSIDIARY

The Company holds a 50% ownership interest in Road and Highway Builders, LLC (“RHB”), with Rich Buenting holding the remaining 50% ownership interest. The Company uses the equity method of accounting for its ownership interest, reporting its portion of RHB’s income as a single line item (“Other operating income (expense), net”) in the Condensed Consolidated Statements of Operations and reporting its interest in RHB as a single line item (“Investment in unconsolidated subsidiary”) in the Condensed Consolidated Balance Sheets.

Financial amounts of RHB and the Company’s share of such amounts are shown below:


(In thousands)	March 31, 2026		December 31, 2025
Current assets - RHB’s Balance Sheets	$	121,928	$	118,101
Current liabilities - RHB’s Balance Sheets	$	120,675	$	123,940
Investment in unconsolidated subsidiary - Sterling’s Balance Sheets (1)	$	100,482	$	105,813

(1) Includes a basis difference of $89.8 million and $91.9 million at March 31, 2026 and December 31, 2025, respectively.


	Three Months Ended March 31,
(In thousands)	2026		2025
RHB’s Statements of Operations
Revenues	$	44,052	$	43,446
Income before tax	$	7,629	$	8,075
Sterling’s Statements of Operations
Revenues	$	—	$	—
Income before tax (1)	$	1,668	$	1,892

(1) For the three months ended March 31, 2026 and 2025, Sterling’s portion of income before tax includes approximately $1.9 million, in each period, of intangible asset amortization and $275 thousand, in each period, of depreciation expense related to the basis difference recognized in the deconsolidation of RHB on December 31, 2024.


6.			CONSTRUCTION JOINT VENTURES

Joint Ventures with a Controlling Interest—We consolidate any venture that is determined to be a VIE for which we are the primary beneficiary, or which we otherwise effectively control. The equity held by the remaining owners and their portions of net income (loss) are reflected in stockholders’ equity on the Condensed Consolidated Balance Sheets line item “Noncontrolling interests” and in the Condensed Consolidated Statements of Operations line item “Net income attributable to noncontrolling interests,” respectively.

Joint Ventures with a Noncontrolling Interest—The Company accounts for unconsolidated joint ventures using a pro-rata basis in the Condensed Consolidated Statements of Operations and as a single line item (“Receivables from and equity in construction joint ventures”) in the Condensed Consolidated Balance Sheets. This method is a permissible modification of the equity method of accounting which is a common practice in the construction industry. Combined financial amounts of joint ventures in which the Company has a noncontrolling interest and the Company’s share of such amounts which are included in the Company’s Condensed Consolidated Financial Statements are shown below:


(In thousands)	March 31, 2026		December 31, 2025
Current assets - Joint Ventures’ Balance Sheets	$	55,099	$	33,326
Current liabilities - Joint Ventures’ Balance Sheets	$	(37,024)	$	(17,877)
Receivables from and equity in construction joint ventures - Sterling's Balance Sheets	$	7,229	$	6,179


	Three Months Ended March 31,
(In thousands)	2026		2025
Joint Ventures’ Statements of Operations:
Revenues	$	21,557	$	19,626
Income before tax	$	2,626	$	163
Sterling’s noncontrolling interest:
Revenues	$	8,623	$	7,850
Income before tax	$	1,050	$	65

The caption “Receivables from and equity in construction joint ventures” includes undistributed earnings and receivables owed to the Company. Undistributed earnings are typically released to the joint venture partners after the customer accepts the project as completed and the warranty period, if any, has passed.

Other—The use of joint ventures exposes us to a number of risks, including the risk that our partners may be unable or unwilling to provide their share of capital investment to fund the operations of the venture or complete their obligations to us, the venture, or ultimately, the customer. Differences in opinions or views among joint venture partners could also result in delayed decision-making or failure to agree on material issues, which could adversely affect the business and operations of the joint venture. In addition, agreement terms may subject us to joint and several liability for our venture partners, and the failure of our venture partners to perform their obligations could impose additional performance and financial obligations on us. The aforementioned factors could result in unanticipated costs to complete the projects, liquidated damages or contract disputes, including claims against our partners.


7.			PROPERTY AND EQUIPMENT

Property and equipment are summarized as follows:


(In thousands)	March 31, 2026		December 31, 2025

Credit Facility—The Company and the subsidiary guarantors have an Amended and Restated Credit Agreement (the “Credit Agreement”) that provides the Company with senior secured debt financing consisting of the following (collectively, the “Credit Facility”): (i) a senior secured first lien term loan facility (the “Term Loan Facility”) in the aggregate principal amount of $300 million and (ii) a senior secured first lien revolving credit facility (the “Revolving Credit Facility”) in an aggregate principal amount of up to $150 million (with a $75 million limit for the issuance of letters of credit and a $15 million sublimit for swing line loans). The obligations under the Credit Facility are secured by substantially all assets of the Company and the subsidiary guarantors, subject to certain permitted liens and other customary exceptions. The Credit Facility will mature on June 5, 2028.

As specified in the Credit Agreement, the loans under the Credit Facility bear interest at a base rate or the Secured Overnight Financing Rate (“SOFR”) plus an applicable margin based on the Total Net Leverage Ratio, at the Company’s election. At March 31, 2026, the Company calculated interest using a SOFR rate of 3.77% and an applicable margin of 1.25% per annum, and had a weighted average interest rate of approximately 5.02% per annum during the three months ended March 31, 2026. Scheduled principal payments on the Term Loan Facility are made quarterly and total approximately $11.3 million for the remainder of 2026, and $15 million and $3.8 million for the years ending 2027 and 2028, respectively. A final payment of all principal and interest then outstanding on the Term Loan Facility is due on June 5, 2028. For the three months ended March 31, 2026, the Company made term loan payments of $3.8 million. Repayments under the Term Loan Facility may not be reborrowed under the terms of the Credit Agreement.

In addition to interest on debt borrowings, we are assessed quarterly commitment fees on the unutilized portion of the Revolving Credit Facility as well as letter of credit fees on outstanding instruments. At March 31, 2026, we had no outstanding borrowings under the $150 million Revolving Credit Facility. Borrowings under the Revolving Credit Facility may be repaid and reborrowed under the terms of the Credit Agreement.

Debt Issuance Costs—The costs associated with the Credit Facility are reflected on the Condensed Consolidated Balance Sheets as a direct reduction from the related debt liability and amortized over the term of the facility. Amortization of debt issuance costs was $204 thousand and $307 thousand for the three months ended March 31, 2026 and 2025, respectively, and was recorded as interest expense.

Compliance and Other—The Credit Agreement contains various affirmative and negative covenants that may, subject to certain exceptions, restrict our ability and the ability of our subsidiaries to, among other things, grant liens, incur additional indebtedness, make loans, advances or other investments, make non-ordinary course asset sales, declare or pay dividends or make other distributions with respect to equity interests, purchase, redeem or otherwise acquire or retire capital stock or other equity interests, or merge or consolidate with any other person, among various other things. In addition, the Company is required to maintain certain financial covenants. As of March 31, 2026, we were in compliance with all of our restrictive and financial covenants. The Company’s debt is recorded at its carrying amount in the Condensed Consolidated Balance Sheets. Based upon the current market rates for debt with similar credit risk and maturities, at March 31, 2026 and December 31, 2025, the fair value of our debt outstanding approximated the carrying value, as interest is based on SOFR plus an applicable margin.


10.			LEASE OBLIGATIONS

11.			COMMITMENTS AND CONTINGENCIES

Insurance

The Company is required by its insurance providers to obtain and hold standby letters of credit. These letters of credit serve as a guarantee by the issuer to pay the Company’s insurance providers the incurred claim costs attributable to its general liability, workers’ compensation and automobile liability claims, up to the amount stated in the standby letters of credit, in the event that these claims were not paid by the Company.

Property and Casualty—The Company has a three-year Structured Reinsurance Program for Workers’ Compensation, General Liability and Auto Liability, which is subject to a $1 million deductible per occurrence, followed by an umbrella program (Workers’ Compensation, General Liability and Auto Liability) that is subject to a corridor deductible of $9 million. We accrue for probable losses, both reported and unreported, that are reasonably estimable using actuarial methods based on historic trends, modified, if necessary, by recent events. Changes in the Company's loss assumptions caused by changes in actual experience would affect our assessment of the ultimate liability and could have an effect on our operating results and

financial position. The Company also maintains commercial insurance coverage in excess of the limits of our primary and umbrella commercial automobile, general liability and employers’ liability policies, in the amount of $70 million.

Medical—The Company maintains fully insured and self-insured medical benefit plans, which provide medical benefits to employees electing coverage under the plans. Under its self-insured plans, the Company has stop-loss coverage per claim to limit the exposure arising from these claims. Self-insured claims filed and claims incurred but not reported are accrued based upon management’s estimates of the ultimate cost of claims incurred using actuarial assumptions followed in the insurance industry and historical experience. Although management believes it has the ability to reasonably estimate losses related to claims, it is possible that actual results could differ from recorded self-insured liabilities.

Guarantees

The Company obtains bonding on construction contracts primarily through Travelers Casualty and Surety Company of America (“Travelers”). As is customary in the construction industry, the Company indemnifies Travelers for any losses incurred by it in connection with bonds that are issued. The Company has granted Travelers a security interest in accounts receivable and contract rights for that obligation.

On certain projects, the Company issues performance guarantees for the remaining cost of work to be performed. For lump-sum contracts, the performance guarantee amount is the cost to complete the contracted work, less amounts remaining to be billed to the client under the contract. Remaining billable amounts could be greater or less than the cost to complete. In those cases where costs exceed the remaining amount billable under the contract, we may have recourse to third parties, such as owners, partners, subcontractors or vendors for claims.

The Company typically indemnifies contract owners for claims arising during the construction process and carries insurance coverage for such claims, which in the past have not been material.

The Company’s Certificate of Incorporation provides for indemnification of its officers and directors. The Company has a directors and officers insurance policy that limits their exposure to litigation against them in their capacities as such.

Litigation

The Company, including its construction joint ventures and its 50% owned subsidiary, is now and may in the future be involved as a party to various legal proceedings that are incidental to the ordinary course of business. Management, after consultation with legal counsel, does not believe that the outcome of these actions will have a material impact on the Condensed Consolidated Financial Statements of the Company. As of March 31, 2026, the Company is not aware of any pending legal proceedings that are expected to result in a material loss.

Purchase Commitments

To manage the risk of changes in material prices and subcontracting costs used in tendering bids for construction contracts, most of the time, we obtain firm quotations from suppliers and subcontractors before submitting a bid. These quotations do not include any quantity guarantees. As soon as we are advised that our bid is successful, we enter into firm contracts with most of our materials suppliers and sub-contractors, thereby mitigating the risk of future price variations affecting the contract costs.


12.			INCOME TAXES

The Company and its subsidiaries are based in the U.S. and file federal and various state income tax returns. The components of the provision for income taxes were as follows:


	Three Months Ended March 31,
(In thousands)	2026		2025
Current federal tax expense	$	24,332	$	10,918
Current state tax expense	7,432		3,512
Deferred federal tax expense	1,982		436
Deferred state tax (benefit) expense	(73)		214
Income tax expense	$	33,673	$	15,080

Cash paid (received) for income taxes	$	—	$	(39)

The effective income tax rate for the three months ended March 31, 2026 was 24.5%. The rate varied from the statutory rate primarily as a result of non-deductible compensation, state income taxes, and other permanent differences. The Company

incurred an approximately $900 thousand tax benefit for the three months ended March 31, 2026 for increased tax deductions related to stock compensation.

The Company's U.S. federal and state income tax returns for 2023 and later are open and subject to examination. Additionally, the federal and state net operating loss (“NOL”) may be adjusted by the taxing authorities for the 2014 and later tax years.

Uncertain Tax Positions (“UTP”)—The Company has a UTP liability of $5.2 million and an additional liability related to the UTP for penalties of $1 million and interest of $1.4 million at March 31, 2026. We recognize interest and penalties related to the UTP as interest and administrative expense, respectively. The UTP, including penalties and interest, is fully offset by an indemnification receivable at March 31, 2026. The Company recognized $1.5 million of the recorded UTP in 2025, with no material impact to the Condensed Consolidated Statement of Operations due to the associated indemnification receivable.


13.			STOCK INCENTIVE PLAN AND OTHER EQUITY ACTIVITY

General—The Company has a stock incentive plan (the “Stock Incentive Plan”) and an employee stock purchase plan (the “ESPP”) that are administered by the Compensation and Talent Development Committee of the Board of Directors. Under the Stock Incentive Plan, the Company can issue shares to employees and directors in the form of restricted stock awards (“RSAs”), restricted stock units (“RSUs”) and performance share units (“PSUs”). Changes in common stock and additional paid in capital during the three months ended March 31, 2026 primarily relate to activity associated with the Stock Incentive Plan, the ESPP, shares withheld for taxes and repurchases of the Company’s common stock.

Share Grants—During the three months ended March 31, 2026, the Company granted the following awards under the Stock Incentive Plan:


(In thousands, except per share data)	Shares	Weighted Average Grant-Date Fair Value per Share

RSUs	20	$	340.17
PSUs – EPS Based (at target)	17	$	306.23
PSUs – Market Based	5	$	428.56

Total shares granted	42

Share Issuances—During the three months ended March 31, 2026, the Company issued the following shares under the Stock Incentive Plan and the ESPP:


(In thousands)						Shares

RSUs (issued upon vesting)						7
PSUs – EPS Based (issued upon vesting)						56


Total shares issued						63

Stock-Based Compensation—The Company recognized $7.3 million and $6.3 million of stock-based compensation expense during the three months ended March 31, 2026 and 2025, respectively. ESPP expense, which is included in the total stock-based compensation expense, was $139 thousand and $87 thousand for the three months ended March 31, 2026 and 2025, respectively. Additionally, the Company has liability-based PSUs for which the number of shares awarded is not determined until the vesting date. During the three months ended March 31, 2026 and 2025, the Company recognized $206 thousand and $339 thousand, respectively, as a liability and compensation expense, and upon vesting, reclassified the grant date fair value of $732 thousand and $632 thousand, respectively, from a liability to additional paid in capital. Stock-based compensation expense is primarily recognized within general and administrative expense. The Company recognizes forfeitures as they occur, rather than estimating expected forfeitures.

Shares Withheld for Taxes—The Company withheld 24 thousand shares for taxes on the vesting of employee stock-based compensation for $10.7 million during the three months ended March 31, 2026.

Treasury Stock—Effective November 12, 2025, the Board of Directors authorized a stock repurchase program, permitting the repurchase of up to $400 million of the Company’s outstanding common stock. The stock repurchase program expires on November 12, 2027 and may be modified, extended or terminated by the Board of Directors at any time. Under the program, the Company may repurchase its common stock in the open market or through privately negotiated transactions at such times and at such prices as determined to be in the Company’s best interest. The Company accounts for the repurchase of treasury shares under the cost method and during the three months ended March 31, 2026, the Company repurchased 40 thousand shares of its common stock for $12.3 million.


14.			EARNINGS PER SHARE

The following table reconciles the numerators and denominators of the basic and diluted earnings per share computations for the three months ended March 31, 2026 and 2025:


(In thousands, except per share data)	Three Months Ended March 31,

Net income per share attributable to Sterling common stockholders:
Basic	$	3.13	$	1.29
Diluted	$	3.09	$	1.28

There were zero and 34 thousand weighted average unvested shares that were excluded from the calculation of diluted EPS under the treasury stock method, as they were anti-dilutive, for the three months ended March 31, 2026 and 2025, respectively.


15.			SUPPLEMENTAL CASH FLOW INFORMATION

Accrued compensation and other liabilities	16,293		(4,128)
Changes in operating assets and liabilities	$	24,602	$	20,386


16.			RELATED PARTY TRANSACTIONS

The Company has a limited number of related party transactions. The most significant transactions relate to property leases with the management of certain subsidiaries who own or have an ownership interest in real estate and other companies. The leases are for office space, equipment yards or maintenance shops and have an annual cost of approximately $5 million. The leases expire at various points over the next one to seven years. During the three months ended March 31, 2026, the Company has performed work for and received services from entities owned or partially owned by the management of certain subsidiaries. For the work performed, the Company earned approximately $1.2 million in revenue, and for the services received, incurred approximately $42 thousand of expense for the three months ended March 31, 2026.

In connection with the CEC Acquisition, the Company recorded a payable to the sellers, some of whom are now related parties, that is directly linked to a project‑specific receivable of approximately $15 million owed to CEC as of the acquisition date. Consistent with the closing settlement mechanics, amounts received from the customer on this receivable will be remitted to the sellers and, accordingly, the Company recognized a liability for the expected remittance. The arrangement does not impact gross profit, as the payable represents a pass‑through of cash collected on a pre‑close balance rather than consideration for post‑close performance. The asset and liability are presented within other current assets and liabilities, respectively, given the expected collection and remittance timeframe of less than 12 months.


17.			SEGMENT INFORMATION

The Company’s internal and public segment reporting are aligned based upon the services offered by its operating segments. The Company’s operations consist of three reportable segments: E-Infrastructure Solutions, Transportation Solutions and Building Solutions. The Company’s CODM, which is the Company’s Chief Executive Officer, uses both segment gross profit and operating income for each segment predominantly in the annual budget and forecasting process. The CODM considers budget-to-actual variances of both profit measures when making decisions about allocating capital and personnel to the segments. We incur certain expenses at the corporate level that relate to our business as a whole. Our business segments receive a portion of these expenses through various allocation methods, predominantly determined by usage and volume. The balance of the corporate level expenses are reported in the “Corporate G&A Expense” line, which is primarily comprised of corporate headquarters facility expense, the cost of the executive management team, and other expenses pertaining to certain centralized functions that benefit the entire Company but are not directly attributable to any specific business segment, such as corporate human resources, legal, governance, compliance and finance functions. Total assets held at Corporate primarily include cash, PP&E, and prepaid and leased assets.

The following tables present segment revenues, significant segment expenses, and measures of segment profit or loss for the three months ended March 31, 2026 and 2025:

•any prolonged shutdown of the government;

•our ability to successfully identify, finance, complete and integrate recent and potential acquisitions or our ability to identify all liabilities associated with an acquired business or asset prior to our acquisition;

•our ability to raise additional capital in the future on favorable terms or at all;

Some of these expectations may be based upon assumptions or judgments that prove to be incorrect. Additional factors or risks that we currently deem immaterial, that are not presently known to us or that arise in the future could also cause our actual results to differ materially from our expected results. Given these uncertainties, investors are cautioned that many of the assumptions upon which our forward-looking statements are based are likely to change after the date the forward-looking statements are made. Further, we may make changes to our business plans that could affect our results.

SIGNIFICANT TRANSACTIONS

CEC Acquisition—On September 1, 2025, the Company acquired substantially all of the assets of Irving, Texas-based CEC Facilities Group, LLC (“CEC”) a leading specialty electrical and mechanical contractor. The purchase price was $561.6 million, consisting primarily of $442.9 million in cash and $79.5 million in common stock. Additionally, CEC has an earn-out opportunity of up to an aggregate of $80 million, contingent upon achieving certain operating income targets. CEC is included in the Company’s E-Infrastructure Solutions segment.

MARKET OUTLOOK AND TRENDS

We see favorable opportunities for long-term growth across each of our business segments. We remain focused on our strategic objectives, which include: 1) growth in our E-Infrastructure Solutions segment, with particular focus on large, high-value projects; 2) risk reduction through a continued shift in our Transportation Solutions business away from low-bid heavy highway work, and toward alternative delivery and design-build projects; 3) continuing to grow market share and geographic presence in Building Solutions; and 4) improving our margins in each of our segments.

E-Infrastructure Solutions—Our E-Infrastructure Solutions business is driven by our customers’ investments in the development of data centers, advanced manufacturing centers, e-commerce distribution centers and warehouses. We foresee significant growth opportunities tied to the implementation of multi-year capital deployment plans by data center customers, including hyperscalers, colocation providers and others. These investments are driven by the need to support the increasing use of cloud computing applications, increasing adoption and complexity of artificial intelligence applications and digital transformation across industries. Additionally, we continue to see significant opportunity related to the construction of manufacturing capacity in the U.S., including semiconductor fabrication. Following a decline that began in 2023, the e-commerce distribution sector began to strengthen in 2025 and we expect this momentum to continue in 2026.

Transportation Solutions—Our Transportation Solutions business is primarily driven by federal, state and municipal funding. Federal funds, on average, provide 50% of annual State Department of Transportation capital outlays for highway and bridge projects. We benefit from a number of federal, state and local infrastructure investment programs. At the Federal level, the Infrastructure Investments and Jobs Act (“IIJA”), which establishes funding for the fiscal 2022 through 2026 time period, drove significant increases in transportation funding relative to the previous five-year law. The IIJA includes approximately $643 billion in funding for transportation programs ($432 billion for highways, $109 billion for transportation and $102 billion for rail), of which $284 billion is an increase over historic investment levels that will fund new transportation infrastructure. The IIJA also includes $25 billion of funding for airport modernization. As a result of the IIJA, we saw an increase in bid activity and project awards which started in the third quarter of 2022 and continued through 2025. In 2026, we expect that the combination of strong state-level funding in our core geographies and elevated federal funding will allow the transportation market to remain strong relative to historical levels.

Building Solutions—Our Building Solutions segment is comprised of our residential and commercial businesses. The segment is driven by new home starts in Dallas-Fort Worth, the segment’s largest market, and continued expansion in the Houston and Phoenix markets. Building Solutions' core customer base includes top national, regional and custom home builders in our areas. Beginning in the second half of 2024, demand from residential home builder customers began to decline, as prospective homebuyers struggled with affordability challenges. We anticipate that demand will remain muted in the near-term, but believe the dynamics in our markets, including population growth and structural housing shortages, support a return to growth over a multi-year time period.

BACKLOG

Our remaining performance obligations on our projects, as defined in ASC 606, do not differ from what we refer to as “Backlog.” Our Backlog represents the amount of revenues we expect to recognize in the future from our contract commitments on projects. The contracts in Backlog are typically completed in 6 to 36 months. Our unsigned awards (“Unsigned Awards”) are excluded from Backlog until the contract is executed by our customer. We refer to the combination of our Backlog and Unsigned Awards as “Combined Backlog.” Our book-to-burn ratio is determined by taking our additions to Backlog and dividing it by revenue for the applicable period. This metric allows management to monitor the Company’s business development efforts to ensure we grow our Backlog and our business over time, and management believes that this measure is useful to investors for the same reason.

At March 31, 2026, our Backlog was $3.80 billion, as compared to $3.01 billion at December 31, 2025, with a book-to-burn ratio of 2.1X for the three months ended March 31, 2026. Unsigned Awards were $1.36 billion at March 31, 2026 and $300.7 million at December 31, 2025. Combined Backlog totaled $5.15 billion and $3.31 billion at March 31, 2026 and December 31, 2025, respectively, with a book-to-burn ratio of 3.5X for the three months ended March 31, 2026.

Gross margin			23.5		%				22.0		%

Revenues—Revenues were $825.7 million for the first quarter of 2026, an increase of $394.7 million, or 92%, compared to the first quarter of 2025. The increase was driven by a $379.5 million increase in E-Infrastructure Solutions, a $12.2 million increase in Transportation Solutions, and a $3.1 million increase in Building Solutions.

Gross profit and margin—Gross profit was $194.3 million for the first quarter of 2026, an increase of $99.5 million, or 105%, compared to the first quarter of 2025. The Company’s gross margin as a percentage of revenue increased to 23.5% in the first quarter of 2026, as compared to 22.0% in the first quarter of 2025. The increases were driven by the aforementioned higher revenue volume and an improved project margin mix in our Transportation Solutions segment.

Our contracts are of various sizes, of different expected profitability and in various stages of completion. The nearer a contract progresses toward completion, the more visibility the Company has in refining its estimate of total revenues (including incentives, delay penalties and change orders), costs and gross profit. Thus, gross profit as a percentage of revenues can increase or decrease from comparable and subsequent quarters due to variations among contracts and the stage of completion of contracts.

General and administrative expense—General and administrative expenses were $47.9 million, or 5.8% of revenue, for the first quarter of 2026, compared to $34.6 million, or 8.0% of revenue, for the first quarter of 2025. The increase in expense reflects higher performance based compensation, increased headcount to support growth, and inflation in 2026.

Interest, net—Combined interest expense and income was net interest expense of $0.4 million for the first quarter of 2026, compared to net interest income of $1.6 million for the first quarter of 2025. The lower interest income was due to decreased interest rates on our lower average cash balance compared to the first quarter of 2025.

Income taxes—The effective income tax rate was 24.5% for the first quarter of 2026. The rate varied from the statutory rate primarily as a result of non-deductible compensation, state income taxes and other permanent differences. See Note 12 - Income Taxes for more information.

Segment Results

The Company’s operations consist of three reportable segments: E-Infrastructure Solutions, Transportation Solutions and Building Solutions. We incur certain expenses at the corporate level that relate to our business as a whole. A portion of these expenses are allocated to our business segments by various methods, but primarily on the basis of usage. The balance of the corporate level expenses are reported in the “Corporate G&A Expense” line, which is primarily comprised of corporate headquarters facility expense, the cost of the executive management team and other expenses pertaining to certain centralized functions that benefit the entire Company, but are not directly attributable to any specific business segment, such as corporate human resources, legal, governance, compliance and finance functions.

E-Infrastructure Solutions

Revenues—Revenues were $597.7 million for the first quarter of 2026, an increase of $379.5 million, or 173.9%, compared to the first quarter of 2025. The increase was primarily driven by higher volume from data centers and the inclusion of $156.1 million of revenue from the electrical and mechanical business acquired late in the third quarter of 2025.

Operating Income—Operating income was $133.8 million, or 22.4% of revenue, for the first quarter of 2026, an increase of $87.1 million, compared to $46.6 million, or 21.4% of revenue, for the first quarter of 2025. The increase in operating income is primarily driven by higher volume from large mission-critical projects, and partly attributable to a $12.3 million (inclusive of $2.3 million of intangible amortization) contribution from the electrical and mechanical business acquired late in the third quarter of 2025.

Transportation Solutions

Revenues—Revenues were $132.9 million for the first quarter of 2026, an increase of $12.2 million, or 10.1%, compared to the first quarter of 2025. The increase was driven by higher aviation and heavy highway revenue.

Operating Income—Operating income was $14.8 million, or 11.1% of revenue, for the first quarter of 2026, an increase of $3.5 million, compared to $11.3 million, or 9.3% of revenue, for the first quarter of 2025. The increase in operating income and margin were driven by the aforementioned revenue volume and an improved project margin mix.

Building Solutions

Revenues—Revenues were $95.1 million for the first quarter of 2026, an increase of $3.1 million, or 3.3%, compared to the first quarter of 2025. The increase was driven by slightly higher residential and commercial volume compared to 2025. Our businesses specializing in residential concrete slabs and plumbing are still being affected by a market downturn, as affordability issues continue to impact potential homebuyers.

Operating Income—Operating income was $6.2 million, or 6.5% of revenue, for the first quarter of 2026, a decrease of $6.1 million, compared to $12.4 million, or 13.4% of revenue, for the first quarter of 2025. The decrease in operating income and margin were driven by a continued downturn in residential markets compared to the first quarter of 2025.

LIQUIDITY AND SOURCES OF CAPITAL

Cash and Cash Equivalents—Total cash and cash equivalents at March 31, 2026 and December 31, 2025 includes the following components:


(In thousands)	March 31, 2026		December 31, 2025
Generally Available	$	406,461	$	314,567
Construction Joint Ventures	105,397		76,154
Cash and cash equivalents	$	511,858	$	390,721

The following table presents consolidated information about our cash flows:


(In thousands)	Three Months Ended March 31,
Net cash provided by (used in):	2026		2025

Operating activities	$	165,568	$	84,883
Investing activities	(17,684)		(54,211)
Financing activities	(26,747)		(56,220)
Net change in cash and cash equivalents	$	121,137	$	(25,548)

Operating Activities—During the three months ended March 31, 2026, net cash provided by operating activities was $165.6 million, compared to net cash provided by operating activities of $84.9 million for the three months ended March 31, 2025. Cash flows provided by operating activities were primarily driven by higher operating income, the collection of receivables from affiliate, distributions of earnings from our unconsolidated subsidiary, and changes in our accounts receivable, net contracts in progress and accounts payable balances (collectively, “Contract Capital”), as discussed below.

Changes in Contract Capital—The change in operating assets and liabilities varies due to fluctuations in operating activities and investments in Contract Capital. The changes in components of Contract Capital during the three months ended March 31, 2026 and 2025 were as follows:


	Three Months Ended March 31,
(In thousands)	2026		2025


Contracts in progress, net	$	12,690	$	31,428
Accounts receivable	(12,740)		(32,233)
Receivables from and equity in construction joint ventures	(1,050)		(1,101)
Accounts payable	4,115		(5,438)
Change in Contract Capital, net	$	3,015	$	(7,344)

During the three months ended March 31, 2026, the change in Contract Capital was $3.0 million. The Company’s Contract Capital fluctuations are impacted by the mix of projects in Backlog, seasonality, the timing of new awards and related payments for work performed and the contract billings to the customer as projects are completed. Contract Capital is also impacted at period-end by the timing of accounts receivable collections and accounts payable payments for projects.

Investing Activities—During the three months ended March 31, 2026, net cash used in investing activities was $17.7 million, compared to net cash used of $54.2 million in the three months ended March 31, 2025. The net cash used during the current period was driven by $19.6 million for purchases of capital equipment, partly offset by $1.9 million of cash proceeds from the sale of property and equipment. Capital equipment is acquired as needed to support changing levels of production activities and to replace retiring equipment.

Financing Activities—During the three months ended March 31, 2026, net cash used in financing activities was $26.7 million, compared to net cash used of $56.2 million for the three months ended March 31, 2025. The financing cash outflow during the period was primarily driven by $12.3 million for the repurchase of common stock, $10.7 million for withholding taxes paid on the net share settlement of vested equity awards, and $3.8 million of repayments on the Term Loan Facility.

Capital Strategy—The Company will continue to explore additional revenue growth and capital alternatives to improve leverage and strengthen its financial position in order to take advantage of trends in the markets in which we operate. The Company also expects to continue to pursue strategic uses of its cash, such as investing in projects or businesses that meet its gross margin and overall profitability targets, managing its debt balances and repurchasing shares of its common stock.

JOINT VENTURES

We participate in various construction joint venture partnerships in order to share expertise, risk and resources for certain highly complex projects. The joint venture’s contract with the project owner typically requires joint and several liability among the joint venture partners. Although our agreements with our joint venture partners provide that each party will assume and fund its share of any losses resulting from a project, if one of our partners is unable to pay its share, we would be fully liable for such share under our contract with the project owner. Circumstances that could lead to a loss under these guarantee arrangements include a partner’s inability to contribute additional funds to the venture in the event that the project incurred a loss or additional costs that we could incur should the partner fail to provide the services and resources toward project completion to which it committed in the joint venture agreement. See the 2025 Form 10-K under “Part I, Item 1A. Risk Factors.”

At March 31, 2026, there was approximately $375 million of construction work to be completed on unconsolidated construction joint venture contracts, of which approximately $150 million represented our proportionate share. Due to the joint and several liability under our joint venture arrangements, if one of our joint venture partners fails to perform, we and the remaining joint venture partners would be responsible for completion of the outstanding work. As of March 31, 2026, we are not aware of any situation that would require us to fulfill responsibilities of our joint venture partners pursuant to the joint and several liability under our contracts.

NEW ACCOUNTING STANDARDS

See the applicable section of Note 2 - Basis of Presentation and Significant Accounting Policies for a discussion of new accounting standards.

CRITICAL ACCOUNTING ESTIMATES

There have been no material changes to the Company’s discussion of critical accounting estimates from those described in Item 7 of our 2025 Form 10-K.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Interest Rate Risk

Our interest rate risk relates primarily to fluctuations in variable interest rates on our revolving credit facility and term loan facility (collectively, the “Credit Facility”) and our cash and cash equivalents balance. Our indebtedness as of March 31, 2026 included $288.8 million of variable rate debt under our Credit Facility. At March 31, 2026 a 100-basis point (or 1%) increase or decrease in the interest rate would increase or decrease interest expense by approximately $3 million per year. As of March 31, 2026, we held cash and cash equivalents of $511.9 million. At March 31, 2026 a 100-basis point (or 1%) increase or decrease in the interest rate would increase or decrease interest income by approximately $5 million per year.

Other

Fair Value—The carrying values of the Company’s cash and cash equivalents, accounts receivable and accounts payable approximate their fair values because of the short-term nature of these instruments. Based upon the current market rates for debt with similar credit risk and maturities, at March 31, 2026, the fair value of our debt outstanding approximated the carrying value, as interest is based on SOFR plus an applicable margin.

Inflation—Since 2021, supply chain volatility and inflation has resulted in price increases in oil, fuel, lumber, concrete, steel and labor which have increased our cost of operations, and inflation has increased our general and administrative expense. Anticipated cost increases are considered in our bids to customers; however, inflation has had, and may continue to have, a negative impact on the Company’s financial results.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures include, but are not limited to, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Securities Exchange Act of 1934 is accumulated and communicated to the issuer’s management, including the principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

The Company’s principal executive officer and principal financial officer reviewed and evaluated the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) as of March 31, 2026. The Company acquired CEC in the third quarter of 2025 and, as permitted by SEC guidance for newly acquired businesses, the scope of management’s assessment of our disclosure controls and procedures as of March 31, 2026 did not include the disclosure controls and procedures, to the extent that they are subsumed by internal control over financial reporting, of CEC, whose financial statements reflect total assets and revenues constituting 28.8% and 18.9%, respectively, of the related Condensed Consolidated Financial Statements of the Company as of, and for the quarter ended, March 31, 2026. Based on that evaluation, the Company’s principal executive officer and principal financial officer concluded that the Company’s disclosure controls and procedures were effective at March 31, 2026 to ensure that the information required to be disclosed by the Company in this Report is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms and is accumulated and communicated to the Company’s management including the principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) during the quarter ended March 31, 2026 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls

Internal control over financial reporting may not prevent or detect all errors and all fraud. Also, projections of any evaluation of effectiveness of internal control to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

PART II—OTHER INFORMATION

Item 1. Legal Proceedings

The Company, including its construction joint ventures and its 50% owned subsidiary, is now and may in the future be involved as a party to various legal proceedings that are incidental to the ordinary course of business. The Company reviews current information about these proceedings and, as necessary, provides accruals for probable liabilities on the eventual disposition of these matters. See Note 11 - “Commitments and Contingencies”, included in the unaudited Notes to our Condensed Consolidated Financial Statements included in Part 1 Item 1. Condensed Consolidated Financial Statements of this Report for additional information.

Item 1A. Risk Factors

There have not been any material changes from the risk factors previously disclosed in “Part I, Item 1A. Risk Factors” of the 2025 Form 10-K. These risk factors should be carefully considered, as they could materially affect the Company’s business, financial condition, or future results.

Items 3 and 4 are not applicable and have been omitted.

Item 5. Other Information

During the quarter ended March 31, 2026, no director or officer (as defined in Rule 16a-1(f) of the Securities Exchange Act of 1934) of the Company adopted or terminated a “Rule 10b5-1 trading arrangement” or “non-Rule 10b5-1 trading arrangement,” as each term is defined in Item 408(a) of Regulation S-K.
