Notes to Consolidated Financial Statements

(unaudited)

Note 1. Overview and Summary of Significant Accounting Policies

Basis of Presentation

Arcosa, Inc. and its consolidated subsidiaries (“Arcosa,” the “Company,” “we,” or “our”), headquartered in Dallas, Texas, is a provider of infrastructure-related products and solutions with leading positions in construction, engineered structures, and transportation markets in North America. Arcosa is a Delaware corporation and was incorporated in 2018 as an independent, publicly-traded company, listed on the New York Stock Exchange.

The accompanying Consolidated Financial Statements are unaudited and have been prepared from the books and records of Arcosa, Inc. and its consolidated subsidiaries. All normal and recurring adjustments necessary for a fair presentation of the financial position of the Company and the results of operations, comprehensive income/loss, and cash flows have been made in conformity with accounting principles generally accepted in the U.S. (“GAAP”). All significant intercompany accounts and transactions have been eliminated. Because of seasonal and other factors, the financial condition and results of operations for the three and six months ended June 30, 2024 may not be indicative of Arcosa's expected business, financial condition, and results of operations for the year ending December 31, 2024.

These interim financial statements and notes are condensed as permitted by the instructions to Form 10-Q and should be read in conjunction with the audited Consolidated Financial Statements of the Company included in its Annual Report on Form 10-K for the year ended December 31, 2023.

Stockholders' Equity

In December 2022, the Company’s Board of Directors (the “Board") authorized a new $50.0 million share repurchase program effective January 1, 2023 through December 31, 2024 to replace a program of the same amount that expired on December 31, 2022. For the three and six months ended June 30, 2024, the Company did not repurchase any shares. As of June 30, 2024, the Company had a remaining authorization of $36.2 million under the program.

Revenue Recognition

Revenue is measured based on the allocation of the transaction price in a contract to satisfied performance obligations. The transaction price does not include any amounts collected on behalf of third parties. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer. The following is a description of principal activities from which the Company generates its revenue, separated by reportable segments. Payments for our products and services are generally due within normal commercial terms. For a further discussion regarding the Company’s reportable segments, see Note 4 Segment Information.

Construction Products

The Construction Products segment recognizes substantially all revenue when the customer has accepted the product and legal title of the product has passed to the customer.

Engineered Structures

Within the Engineered Structures segment, revenue is recognized for wind towers and certain utility structures over time as the products are manufactured using an input approach based on the costs incurred relative to the total estimated costs of production. We recognize revenue over time for these products as they are highly customized to the needs of an individual customer resulting in no alternative use to the Company if not purchased by the customer after the contract is executed. In addition, we have the right to bill the customer for our work performed to date plus at least a reasonable profit margin for work performed. As of June 30, 2024, we had a contract asset of $76.7 million related to these contracts, compared to $66.8 million as of December 31, 2023, which is included in receivables, net of allowance, within the Consolidated Balance Sheets. The increase in the contract asset is attributed to timing of deliveries of finished structures to customers during the period. For all other products, revenue is recognized when the customer has accepted the product and legal title of the product has passed to the customer.

Transportation Products

The Transportation Products segment recognizes revenue when the customer has accepted the product and legal title of the product has passed to the customer.

Table of Contents

Unsatisfied Performance Obligations

The following table includes estimated revenue expected to be recognized in future periods related to performance obligations that are unsatisfied or partially satisfied as of June 30, 2024 and the percentage of the outstanding performance obligations as of June 30, 2024 expected to be delivered during the remainder of 2024:


	Unsatisfied performance obligations as of June 30, 2024
	Total Amount		Percent expected to be delivered in 2024
	(in millions)
Engineered Structures:
Utility, wind, and related structures	$	1,338.7	37	%


Transportation Products:
Inland barges	$	251.5	69	%

Of the remaining unsatisfied performance obligations for utility, wind, and related structures, 32% are expected to be delivered during 2025 with the remainder expected to be delivered through 2028. All of the remaining unsatisfied performance obligations for inland barges are expected to be delivered during 2025.

Income Taxes

The liability method is used to account for income taxes. Deferred income taxes represent the tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Valuation allowances reduce deferred tax assets to an amount that will more likely than not be realized.

The Company regularly evaluates the likelihood of realization of tax benefits derived from positions it has taken in various federal and state filings after consideration of all relevant facts, circumstances, and available information. For those tax positions that are deemed more likely than not to be sustained, the Company recognizes the benefit it believes is cumulatively greater than 50% likely to be realized. To the extent the Company were to prevail in matters for which accruals have been established or be required to pay amounts in excess of recorded reserves, the effective tax rate in a given financial statement period could be materially impacted.

Financial Instruments

The Company considers all highly liquid debt instruments to be cash and cash equivalents if purchased with a maturity of three months or less. Financial instruments that potentially subject the Company to a concentration of credit risk are primarily cash investments and receivables. The Company places its cash investments in bank deposits and highly-rated money market funds, and its investment policy limits the amount of credit exposure to any one commercial issuer. We seek to limit concentrations of credit risk with respect to receivables with control procedures that monitor the credit worthiness of customers, together with the large number of customers in the Company's customer base and their dispersion across different industries and geographic areas. As receivables are generally unsecured, the Company maintains an allowance for doubtful accounts based upon the expected credit losses. Receivable balances determined to be uncollectible are charged against the allowance. To accelerate the conversion to cash, the Company may sell a portion of its trade receivables to third parties. The Company has no recourse to these receivables once they are sold but may have continuing involvement related to servicing and collection activities. The impact of these transactions in the Company's Consolidated Statements of Operations for the three and six months ended June 30, 2024 was not significant. The carrying values of cash, receivables, and accounts payable are considered to be representative of their respective fair values.

Table of Contents

Derivative Instruments

The Company may, from time to time, use derivative instruments to mitigate the impact of changes in interest rates, commodity prices, or changes in foreign currency exchange rates. For derivative instruments designated as hedges, the Company formally documents the relationship between the derivative instrument and the hedged item, as well as the risk management objective and strategy for the use of the derivative instrument. This documentation includes linking the derivative to specific assets or liabilities on the balance sheet, commitments, or forecasted transactions. At the time a derivative instrument is entered into, and at least quarterly thereafter, the Company assesses whether the derivative instrument is effective in offsetting the changes in fair value or cash flows of the hedged item. Any change in the fair value of the hedged instrument is recorded in accumulated other comprehensive loss (“AOCL”) as a separate component of stockholders' equity and reclassified into earnings in the period during which the hedged transaction affects earnings. When derivative instruments are in place, the Company monitors its positions and the credit ratings of its counterparties to mitigate the risk of loss due to counterparties' non-performance.

Recent Accounting Pronouncements

Recently adopted accounting pronouncements

Effective January 1, 2024, the Company adopted Accounting Standards Update No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” (“ASU 2023-07”), which is intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The Company will adopt additional disclosure requirements within its annual reporting for the year ending December 31, 2024 and its interim reporting for the quarter ending March 31, 2025.

Recently issued accounting pronouncements not adopted as of June 30, 2024

In December 2023, the FASB issued Accounting Standards Update No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”), which is intended to improve the transparency of income tax disclosures by requiring 1) consistent categories and greater disaggregation of information in the rate reconciliation and 2) income taxes paid disaggregated by jurisdiction. The standard also includes certain other amendments to improve the effectiveness of income tax disclosures. ASU 2023-09 will become effective for public companies during annual reporting periods beginning after December 15, 2024, with early adoption permitted. Although ASU 2023-09 only modifies the Company's required income tax disclosures, the Company is currently evaluating the impact of adopting this guidance on its Consolidated Financial Statements.

Note 2. Acquisitions and Divestitures

2024 Acquisitions

On August 1, 2024, we entered into an agreement to acquire the construction materials business of Stavola Holding Corporation and its affiliated entities ("Stavola") for $1.2 billion in cash. Stavola, which will be reported within the Construction Products segment, serves the New York-New Jersey market through its network of five natural aggregates quarries, twelve asphalt plants, and three recycled aggregates sites. The Company has obtained $1.2 billion of committed secured bridge loan financing, as well as a backstop to its existing $600.0 million revolving credit facility. Prior to the transaction close, the Company anticipates accessing the long-term debt capital markets for permanent financing with a mix of secured and unsecured debt. The transaction is expected to close in the fourth quarter.

In July 2024, we completed the acquisition of a Phoenix, Arizona based natural aggregates business in our Construction Products segment, for a total purchase price of $35.0 million.

Table of Contents

On April 9, 2024, we completed the acquisition of Ameron Pole Products LLC ("Ameron"), a leading manufacturer of highly engineered, premium concrete and steel poles for a broad range of infrastructure applications, including lighting, traffic, electric distribution, and small-cell telecom, for a total purchase price of $180.0 million. With operations in Alabama, California, and Oklahoma, Ameron is included in our Engineered Structures segment. The acquisition was funded with $160.0 million of borrowings under our revolving credit facility and cash on hand. The acquisition was recorded as a business combination based on a preliminary valuation of the assets acquired and liabilities assumed at their acquisition date fair value using unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities ("Level 3" inputs). The preliminary valuation resulted in the recognition of, among others, $55.9 million of property, plant, and equipment, $27.9 million of customer relationships, $18.2 million of inventory, $12.8 million of technology, $12.1 million of accounts receivable, $8.9 million of trademarks and $42.9 million of goodwill in our Engineered Structures segment. The goodwill acquired, which is tax-deductible, primarily relates to Ameron's market position and existing workforce. We expect to complete our purchase price allocation as soon as reasonably possible, not to exceed one year from the acquisition date. Adjustments to the preliminary purchase price allocation could be material, particularly with respect to our preliminary estimates of property, plant, and equipment, customer relationships, and technology.

2023 Acquisitions

On December 20, 2023, we completed the acquisition of certain assets and liabilities of Lake Point Holdings, LLC and Lake Point Restoration LLC, (collectively "Lake Point") a Florida based natural aggregates business in our Construction Products segment, for a total purchase price of $65.1 million. The acquisition was funded with $60.0 million of borrowings under our revolving credit facility and cash on hand. The acquisition was recorded as a business combination based on a valuation of the assets acquired and liabilities assumed at their acquisition date fair value using Level 3 inputs. The preliminary valuation resulted in the recognition of, among others, $13.2 million of property, plant, and equipment, $19.1 million of mineral reserves, $11.5 million of permits, and $15.4 million of goodwill in our Construction Products segment. We expect to complete our purchase price allocation as soon as reasonably possible, not to exceed one year from the acquisition date. Adjustments to the preliminary purchase price allocation could be material, particularly with respect to our preliminary estimates of mineral reserves, permits, and property, plant, and equipment.

In October 2023, we completed the acquisition of certain assets and liabilities of a Phoenix, Arizona based recycled aggregates business and the acquisition of certain assets and liabilities of a Florida based recycled aggregates business in our Construction Products segment. The purchase prices of these acquisitions were not significant.

In September 2023, we completed the acquisition of certain assets and liabilities of a Houston, Texas based stabilized sand producer in our Construction Products segment. The purchase price of the acquisition was not significant.

In March 2023, we completed the stock acquisition of a Houston, Texas based shoring, trench, and excavation products business in our Construction Products segment. In February 2023, we completed the acquisition of certain assets and liabilities of a Phoenix, Arizona based recycled aggregates business in our Construction Products segment. The purchase prices of these acquisitions were not significant.

Divestitures

On August 1, 2024, the Company entered into an agreement to sell its steel components business. The steel components business, reported in the Transportation Products segment, is a leading supplier of railcar coupling devices, railcar axles, and circular forgings. The transaction is expected to close during the third quarter.

During the three months ended June 30, 2024, we completed the divestiture of certain assets and liabilities of a single-location asphalt and paving operation in our Construction Products segment and the sale of a non-operating facility in our Engineered Structures segment.

The total consideration for these divestitures is expected to be approximately $137.3 million. For the divestitures that closed during the three months ended June 30, 2024, the Company recognized a pre-tax gain of $12.5 million which is reflected in gain on sale of businesses on the Consolidated Statement of Operations.

There were no divestitures completed during the three and six months ended June 30, 2023.

In June 2023, the Company settled a $15.0 million holdback obligation from the 2021 acquisition of Southwest Rock Products, LLC upon the extension of a certain mineral reserve lease. Based on final negotiations with the seller, the holdback was settled for $10.0 million and paid during the three months ended June 30, 2023. The $5.0 million difference between the settlement amount and the amount accrued at the time of acquisition was recorded as a reduction in cost of revenues in the Consolidated Statement of Operations.

(1) Current portion included in accrued liabilities and non-current portion included in other liabilities on the Consolidated Balance Sheets.

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for that asset or liability in an orderly transaction between market participants on the measurement date. An entity is required to establish a fair value hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. The three levels of inputs that may be used to measure fair values are listed below:

Level 1 – This level is defined as quoted prices in active markets for identical assets or liabilities. The Company’s cash equivalents are instruments of the U.S. Treasury or highly-rated money market mutual funds.

Level 2 – This level is defined as observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Interest rate hedges are valued at exit prices obtained from each counterparty. See Note 7 Debt.

Level 3 – This level is defined as unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Contingent consideration relates to estimated future payments owed to the sellers of businesses previously acquired. We estimate the fair value of the contingent consideration using a discounted cash flow model. The fair value is sensitive to changes in the forecast of sales and changes in discount rates and is reassessed quarterly based on assumptions used in our latest projections.

	$	1,023.4	$	990.7

The decrease in Construction Products goodwill during the six months ended June 30, 2024 is due to measurement period adjustments from the 2023 acquisitions and the divestiture of a single-location asphalt and paving business completed in April 2024. The increase in Engineered Structures goodwill during the six months ended June 30, 2024 is due to the recent acquisition of Ameron. See Note 2 Acquisitions and Divestitures.

Revolving Credit Facility

On August 23, 2023, we entered into a Second Amended and Restated Credit Agreement to increase our revolving credit facility from $500.0 million to $600.0 million, extend the maturity date of the revolving credit facility from January 2, 2025 to August 23, 2028, and refinance and repay in full the remaining balance of the term loan then outstanding under our prior credit facility.

In April 2024, we borrowed an additional $160.0 million under our revolving credit facility to fund, in part, the acquisition of Ameron, of which $60.0 million was repaid during the three months ended June 30, 2024. As of June 30, 2024, we had $300.0 million of outstanding loans borrowed under the revolving credit facility, and there were approximately $10.7 million of letters of credit issued, leaving $289.3 million available for borrowing. Of the outstanding letters of credit as of June 30, 2024, $10.7 million are expected to expire in 2025. The majority of our letters of credit obligations support the Company’s various insurance programs and generally renew by their terms each year.

The interest rates under the revolving credit facility are variable based on the daily simple or term Secured Overnight Financing Rate ("SOFR"), plus a 10-basis point credit spread adjustment, or an alternate base rate, in each case plus a margin for borrowing. A commitment fee accrues on the average daily unused portion of the revolving facility. The margin for borrowing and commitment fee rate are determined based on the Company’s leverage as measured by a consolidated total indebtedness to consolidated EBITDA ratio. The margin for borrowing based on SOFR ranges from 1.25% to 2.00% and was set at 1.50% as of June 30, 2024. The commitment fee rate ranges from 0.20% to 0.35% and was set at 0.25% at June 30, 2024.

The Company's revolving credit facility requires the maintenance of certain ratios related to leverage and interest coverage. As of June 30, 2024, we were in compliance with all such financial covenants. Borrowings under the revolving credit facility are guaranteed by certain domestic subsidiaries of the Company.

The carrying value of borrowings under our revolving credit approximates fair value because the interest rate adjusts to the market interest rate (Level 3 input). See Note 3 Fair Value Accounting.

As of June 30, 2024, the Company had $2.1 million of unamortized debt issuance costs related to the revolving credit facility, which are included in other assets on the Consolidated Balance Sheet.

Senior Notes

On April 6, 2021, the Company issued $400.0 million aggregate principal amount of 4.375% senior notes (the “Notes”) that mature in April 2029. Interest on the Notes is payable semiannually in April and October. The Notes are senior unsecured obligations of the Company and are guaranteed on a senior unsecured basis by each of the Company’s domestic subsidiaries that is a guarantor under our revolving credit facility. The terms of the indenture governing the Notes, among other things, limit the ability of the Company and each of its subsidiaries to create liens on assets, enter into sale and leaseback transactions, and consolidate, merge or transfer all or substantially all of its assets and the assets of its subsidiaries. The terms of the indenture also limit the ability of the Company’s non-guarantor subsidiaries to incur certain types of debt.

The Company has the option to redeem all or a portion of the Notes at redemption prices set forth in the indenture, plus accrued and unpaid interest to the redemption date. If a Change of Control Triggering Event (as defined in the indenture) occurs, the Company must offer to repurchase the Notes at a price equal to 101% of the principal amount of the Notes, plus accrued and unpaid interest to the date of repurchase.

Table of Contents

The estimated fair value of the Notes as of June 30, 2024 was $370.3 million based on a quoted market price in a market with little activity (Level 2 input).

In connection with the issuance of the Notes, the Company paid $6.6 million of debt issuance costs.

The remaining principal payments under existing debt agreements as of June 30, 2024 are as follows:

Interest rate hedges

In December 2018, the Company entered into a $100.0 million interest rate swap instrument, effective as of January 2, 2019, to reduce the effect of changes in the variable interest rates associated with the first $100.0 million of borrowings under the Company's committed credit facility. In conjunction with the replacement of LIBOR with SOFR as a benchmark for borrowings under the Amended and Restated Credit Agreement, on July 1, 2023 the swap instrument transitioned from LIBOR to SOFR. The instrument effectively fixed the SOFR component of borrowings under the revolving credit facility at a monthly rate of 2.71% until such instrument's termination. The interest rate swap instrument expired in October 2023.

Note 8. Leases

We have various leases primarily for office space and certain equipment. At inception, we determine if an arrangement contains a lease and whether that lease meets the classification criteria of a finance or operating lease. For leases that contain options to purchase, terminate, or extend, such options are included in the lease term when it is reasonably certain that the option will be exercised. Some of our lease arrangements contain lease components and non-lease components which are accounted for as a single lease component as we have elected the practical expedient to group lease and non-lease components for all leases.

As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on information available at commencement date in determining the present value of lease payments.

Future minimum lease payments for operating and finance lease obligations as of June 30, 2024 consisted of the following:


	Operating Leases		Finance Leases
	(in millions)
2024 (remaining)	$	5.0	$	3.7

Note 10. Income Taxes

For interim income tax reporting, we estimate our annual effective tax rate and apply it to our year-to-date ordinary income (loss). Tax jurisdictions with a projected or year to date loss for which a tax benefit cannot be realized are excluded. The tax effects of unusual or infrequently occurring items, including changes in judgment about valuation allowances and effects of changes in tax laws or rates, are reported in the interim period in which they occur. We have open tax years from 2014 to 2023 with various significant tax jurisdictions.

Our effective tax rates of 14.3% and 15.6% for the three and six months ended June 30, 2024, respectively, differed from the U.S. federal statutory rate of 21.0% due to Advanced Manufacturing Production ("AMP") tax credits, compensation-related items, state income taxes, statutory depletion deductions, and tax effects of foreign currency translations. Our effective tax rates of 12.0% and 17.0% for the three and six months ended June 30, 2023, respectively, differed from the U.S. federal statutory rate of 21.0% due to AMP tax credits, tax effects of foreign currency translations, compensation-related items, state income taxes, and statutory depletion deductions.

Note 14. Earnings Per Common Share

Basic earnings per common share is computed by dividing net income remaining after allocation to participating unvested restricted shares by the weighted average number of basic common shares outstanding for the period. Except when the effect would be antidilutive, the calculation of diluted earnings per common share includes the weighted average net impact of nonparticipating unvested restricted shares. Total weighted average restricted shares were 1.2 million for the three and six months ended June 30, 2024. Total weighted average restricted shares were 1.3 million and 1.4 million for the three and six months ended June 30, 2023, respectively.

The computation of basic and diluted earnings per share follows.

Note 15. Contingencies

The Company is involved in claims and lawsuits incidental to our business arising from various matters including commercial disputes, alleged product defect and/or warranty claims, intellectual property matters, personal injury claims, environmental issues, employment and/or workplace-related matters, and various governmental and environmental regulations. The Company evaluates its exposure to such claims and suits periodically and establishes accruals for these contingencies when probable losses can be reasonably estimated. At June 30, 2024, the reasonably possible losses and any related accruals for such matters were not significant.

Estimates of liability arising from future proceedings, assessments, or remediation are inherently imprecise. Accordingly, there can be no assurance that we will not become involved in future litigation or other proceedings, including those related to the environment or, if we are found to be responsible or liable in any such litigation or proceeding, that such costs would not be material to the Company.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) is intended to provide a reader of our financial statements with a narrative from the perspective of our management on our financial condition, results of operations, liquidity, and certain other factors that may affect our future results. Our MD&A is presented in the following sections:

•Company Overview

•Market Outlook

•Executive Overview

•Results of Operations

•Liquidity and Capital Resources

•Recent Accounting Pronouncements

•Forward-Looking Statements

Our MD&A should be read in conjunction with the Consolidated Financial Statements of Arcosa, Inc. and its consolidated subsidiaries (“Arcosa,” “Company,” “we,” or “our”) and related Notes in Part I, Item 1 of this Quarterly Report on Form 10-Q and the Consolidated Financial Statements and related Notes in Item 8, “Financial Statements and Supplementary Data”, of our Annual Report on Form 10-K for the year ended December 31, 2023 (“2023 Annual Report on Form 10-K”).

Company Overview

Arcosa, headquartered in Dallas, Texas, is a provider of infrastructure-related products and solutions with leading positions in construction, engineered structures, and transportation markets in North America. Arcosa is a Delaware corporation and was incorporated in 2018 as an independent, publicly-traded company, listed on the New York Stock Exchange.

Market Outlook

•Within our Construction Products segment, market demand remains healthy overall when seasonal weather conditions have been normal, supported by increased infrastructure spending and private non-residential activity. The outlook for single-family residential housing continues to be impacted by higher interest rates and home affordability, which has negatively impacted volumes. We have been successful in managing inflationary cost pressures through proactive price increases.

•Within our Engineered Structures segment, our backlog as of June 30, 2024 provides good production visibility for the remainder of 2024. Our customers remain committed to taking delivery of these orders. In utility structures, order and inquiry activity continues to be healthy, as customers remain focused on grid hardening and reliability initiatives. The passage of the Inflation Reduction Act ("IRA") on August 16, 2022, which included a long-term extension of the Production Tax Credit (“PTC”) for new wind farm projects and introduced new Advanced Manufacturing Production (“AMP”) tax credits for companies that domestically manufacture and sell clean energy equipment in the U.S., is a significant catalyst for our wind towers business. As demonstrated by more than $1.1 billion of new orders for delivery through 2028, which we have received since the passage of the IRA, our wind towers business is at the beginning stages of a market recovery. A large portion of these orders will support wind energy expansion projects in the Southwest. As a result, we have opened a new plant in New Mexico and have started delivering towers from this facility late in the second quarter of 2024.

•Within our Transportation Products segment, our backlog for inland barges as of June 30, 2024 was $251.5 million and extends into 2025. Our customers remain committed to taking delivery of these orders. Our barge business is recovering from cyclical lows resulting from the onset of the COVID-19 pandemic when order levels fell sharply and have remained low due to persistently high steel prices. Over this time, customer inquiries have remained healthy, initially for dry barges and more recently for tank barges. The fleet continues to age as new builds have not kept pace with scrapping, and utilization rates are high. We have been successful in filling orders when we can strategically source steel. During the second quarter, we received orders of $33 million primarily for tank barges. Demand for steel components has stabilized as the near-term outlook for the new railcar market indicates replacement-level demand.

Executive Overview

Recent Developments

In August 2024, the Company entered into an agreement to acquire the construction materials business of Stavola Holding Corporation and its affiliated entities ("Stavola") for $1.2 billion in cash. Stavola, which will be reported within the Construction Products segment, serves the New York-New Jersey market through its network of five natural aggregates quarries, twelve asphalt plants, and three recycled aggregates sites. The Company has obtained $1.2 billion of committed secured bridge loan financing, as well as a backstop to its existing $600 million revolving credit facility. Prior to the transaction close, the Company anticipates accessing the long-term debt capital markets for permanent financing with a mix of secured and unsecured debt. The transaction is expected to close in the fourth quarter.

Concurrently, the Company announced it has entered into an agreement to sell its steel components business. The steel components business, reported in the Transportation Products segment, is a leading supplier of railcar coupling devices, railcar axles, and circular forgings. The transaction is expected to close during the third quarter.

In April 2024, we completed the acquisition of Ameron Pole Products, LLC ("Ameron"), a leading manufacturer of highly engineered, premium concrete and steel poles for a broad range of infrastructure applications, including lighting, traffic, electric distribution, and small-cell telecom, for a total purchase price of $180.0 million. With operations in Alabama, California, and Oklahoma, Ameron is included in our Engineered Structures segment. The acquisition was funded with $160.0 million of borrowings under our revolving credit facility and cash on hand.

Three Months Ended June 30, 2024 versus Three Months Ended June 30, 2023

•Revenues increased 4.3% primarily due to recent acquisitions. Organic revenues in our aggregates and specialty materials businesses were roughly flat as higher pricing was mostly offset by lower volumes primarily due to elevated rainfall during the period, a decrease in freight revenue, and a reduction in revenue from recently divested operations. Revenues in our trench shoring business increased 7.7% primarily due to higher volumes.

•Cost of revenues increased 3.4% primarily due to increased costs from the recently acquired businesses, including higher depreciation, depletion, and amortization expense and the cost impact of the fair market value write-up of acquired inventory and a $5.0 million benefit recognized in the prior period related to the reduction in a holdback obligation owed on a previous acquisition. The increase was partially offset by lower organic volumes in our aggregates and specialty materials businesses and operating improvements in our specialty materials and trench shoring businesses. As a percentage of revenues, cost of revenues decreased to 75.4% in the current period, compared to 76.1% in the prior period.

•Selling, general, and administrative expenses decreased 1.4% due to lower costs in our aggregates and trench shoring businesses. Selling, general, and administrative expenses as a percentage of revenues was 10.5% in the current period, compared to 11.1% in the prior period.

•During the current period, the segment recognized a $5.0 million gain on the sale of an under-performing single-location asphalt and paving operation and an impairment charge of $5.8 million related to the closure of its aggregates operations in west Texas for a net reduction in operating profit of $0.8 million.

•Operating profit increased 14.5% primarily due to the accretive impact of recent acquisitions and operating improvements in our specialty materials business and trench shoring businesses, partially offset by the benefit from the holdback payment in the prior period.

•Depreciation, depletion, and amortization expense increased 5.8% primarily due to the fair market value write-up of long-lived assets from recent acquisitions and organic growth investments.

Six Months Ended June 30, 2024 versus Six Months Ended June 30, 2023

•Revenues increased 5.3% primarily due to recent acquisitions. Organic revenue in our aggregates and specialty materials businesses were up slightly as higher pricing more than offset the lower volumes driven by abnormally wet weather, a decrease in freight revenue, and a reduction in revenue from recently divested operations.

Liquidity and Capital Resources

Arcosa’s primary liquidity requirement consists of funding our business operations, including capital expenditures, working capital investment, and disciplined acquisitions. Our primary sources of liquidity include cash flow from operations, our existing cash balance, availability under the revolving credit facility, and, as necessary, the issuance of additional long-term debt or equity. To the extent we have available liquidity, we may also consider undertaking new capital investment projects, executing additional strategic acquisitions, returning capital to stockholders, or funding other general corporate purposes.

Cash Flows

Other Investing and Financing Activities

Revolving Credit Facility and Senior Notes

On August 23, 2023, we entered into a Second Amended and Restated Credit Agreement to increase the revolving credit facility from $500.0 million to $600.0 million, extend the maturity date of the revolving credit facility from January 2, 2025 to August 23, 2028, and refinance and repay in full the remaining balance of the term loan then outstanding under the prior credit facility.

Table of Contents

The interest rates under the revolving credit facility are variable based on the daily simple or term Secured Overnight Financing Rate ("SOFR"), plus a 10-basis point credit spread adjustment, or an alternate base rate, in each case plus a margin for borrowing. A commitment fee accrues on the average daily unused portion of the revolving facility. The margin for borrowing and commitment fee rate are determined based on Arcosa’s leverage as measured by a consolidated total indebtedness to consolidated EBITDA ratio. The margin for borrowing based on SOFR ranges from 1.25% to 2.00% and was set at 1.50% as of June 30, 2024. The commitment fee rate ranges from 0.20% to 0.35% and was set at 0.25% as of June 30, 2024.

We believe, based on our current business plans, that our existing cash, available liquidity, and cash flow from operations will be sufficient to fund necessary capital expenditures and operating cash requirements for the foreseeable future.

Any forward-looking statement speaks only as of the date on which such statement is made. Arcosa undertakes no obligation to update any forward-looking statement to reflect events or circumstances after the date on which such statement is made. For a discussion of risks and uncertainties that could cause actual results to differ from those contained in the forward-looking statements, see Item 1A, “Risk Factors” in our 2023 Annual Report on Form 10-K and future Quarterly Reports on Form 10-Q and Current Reports on Form 8-K.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

There has been no material change in our market risks since December 31, 2023 as set forth in our 2023 Annual Report on Form 10-K. See Note 9 Other, Net of the Notes to the Consolidated Financial Statements for the impact of foreign exchange rate fluctuations for the three and six months ended June 30, 2024.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

The Company maintains disclosure controls and procedures designed to ensure that it is able to collect and record the information it is required to disclose in the reports it files or submits under the Securities Exchange Act of 1934 (the “Exchange Act”) with the Securities and Exchange Commission (“SEC”), to process, summarize, and disclose this information within the time periods specified in the rules of the SEC, and that such information is accumulated and communicated to management, including our Chief Executive and Chief Financial Officers, in a timely fashion. The Company’s Chief Executive and Chief Financial Officers are responsible for establishing and maintaining these disclosure controls and procedures and evaluating their effectiveness (as defined in Rule 13(a)-15l under the Exchange Act). Based on their evaluation of the Company’s disclosure controls and procedures that took place as of the end of the period covered by this report, the Chief Executive and Chief Financial Officers believe that these disclosure controls and procedures were effective.

Changes in Internal Control over Financial Reporting

During the period covered by this report, there have been no changes in the Company’s internal control over financial reporting that have materially affected or are reasonably likely to materially affect the Company’s internal control over financial reporting.

As permitted by the SEC Staff interpretive guidance for recently acquired businesses, management's assessment and conclusion on the effectiveness of the Company's disclosure controls and procedures as of June 30, 2024 excludes an assessment of the internal control over financial reporting of the Ameron business acquired in April 2024. Ameron represents approximately 5% of consolidated total assets and 2% of consolidated revenues as of and for the six months ended June 30, 2024.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

This table provides information with respect to purchases by the Company of shares of its common stock during the quarter ended June 30, 2024:


Period	Number of Shares Purchased (1)	Average Price Paid per Share (1)		Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs (2)	Maximum Number (or Approximate Dollar Value) of Shares that May Yet Be Purchased Under the Plans or Programs (2)
April 1, 2024 through April 30, 2024	24	$	84.14	—	$	36,247,953
May 1, 2024 through May 31, 2024	101,943	$	89.23	—	$	36,247,953
June 1, 2024 through June 30, 2024	990	$	86.41	—	$	36,247,953
Total	102,957	$	89.20	—	$	36,247,953

(1) These columns include the following transactions during the three months ended June 30, 2024: (i) the surrender to the Company of 102,957 shares of common stock to satisfy tax withholding obligations in connection with the vesting of restricted stock issued to employees and (ii) the purchase of no shares of common stock on the open market as part of the stock repurchase program.

Among other things, the IRA imposes a 1% excise tax on the fair market value of stock repurchases made by covered corporations after December 31, 2022. We have evaluated these new provisions, concluded there is no impact for the three and six months ended June 30, 2024, and continue to evaluate the impact of these tax law changes on future periods.

Acquisitions and Divestitures	Jun. 30, 2024
Business Combinations [Abstract]
Acquisitions and Divestitures	Acquisitions and Divestitures 2024 Acquisitions On August 1, 2024, we entered into an agreement to acquire the construction materials business of Stavola Holding Corporation and its affiliated entities ("Stavola") for $1.2 billion in cash. Stavola, which will be reported within the Construction Products segment, serves the New York-New Jersey market through its network of five natural aggregates quarries, twelve asphalt plants, and three recycled aggregates sites. The Company has obtained $1.2 billion of committed secured bridge loan financing, as well as a backstop to its existing $600.0 million revolving credit facility. Prior to the transaction close, the Company anticipates accessing the long-term debt capital markets for permanent financing with a mix of secured and unsecured debt. The transaction is expected to close in the fourth quarter. In July 2024, we completed the acquisition of a Phoenix, Arizona based natural aggregates business in our Construction Products segment, for a total purchase price of $35.0 million. On April 9, 2024, we completed the acquisition of Ameron Pole Products LLC ("Ameron"), a leading manufacturer of highly engineered, premium concrete and steel poles for a broad range of infrastructure applications, including lighting, traffic, electric distribution, and small-cell telecom, for a total purchase price of $180.0 million. With operations in Alabama, California, and Oklahoma, Ameron is included in our Engineered Structures segment. The acquisition was funded with $160.0 million of borrowings under our revolving credit facility and cash on hand. The acquisition was recorded as a business combination based on a preliminary valuation of the assets acquired and liabilities assumed at their acquisition date fair value using unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities ("Level 3" inputs). The preliminary valuation resulted in the recognition of, among others, $55.9 million of property, plant, and equipment, $27.9 million of customer relationships, $18.2 million of inventory, $12.8 million of technology, $12.1 million of accounts receivable, $8.9 million of trademarks and $42.9 million of goodwill in our Engineered Structures segment. The goodwill acquired, which is tax-deductible, primarily relates to Ameron's market position and existing workforce. We expect to complete our purchase price allocation as soon as reasonably possible, not to exceed one year from the acquisition date. Adjustments to the preliminary purchase price allocation could be material, particularly with respect to our preliminary estimates of property, plant, and equipment, customer relationships, and technology. 2023 Acquisitions On December 20, 2023, we completed the acquisition of certain assets and liabilities of Lake Point Holdings, LLC and Lake Point Restoration LLC, (collectively "Lake Point") a Florida based natural aggregates business in our Construction Products segment, for a total purchase price of $65.1 million. The acquisition was funded with $60.0 million of borrowings under our revolving credit facility and cash on hand. The acquisition was recorded as a business combination based on a valuation of the assets acquired and liabilities assumed at their acquisition date fair value using Level 3 inputs. The preliminary valuation resulted in the recognition of, among others, $13.2 million of property, plant, and equipment, $19.1 million of mineral reserves, $11.5 million of permits, and $15.4 million of goodwill in our Construction Products segment. We expect to complete our purchase price allocation as soon as reasonably possible, not to exceed one year from the acquisition date. Adjustments to the preliminary purchase price allocation could be material, particularly with respect to our preliminary estimates of mineral reserves, permits, and property, plant, and equipment. In October 2023, we completed the acquisition of certain assets and liabilities of a Phoenix, Arizona based recycled aggregates business and the acquisition of certain assets and liabilities of a Florida based recycled aggregates business in our Construction Products segment. The purchase prices of these acquisitions were not significant. In September 2023, we completed the acquisition of certain assets and liabilities of a Houston, Texas based stabilized sand producer in our Construction Products segment. The purchase price of the acquisition was not significant. In March 2023, we completed the stock acquisition of a Houston, Texas based shoring, trench, and excavation products business in our Construction Products segment. In February 2023, we completed the acquisition of certain assets and liabilities of a Phoenix, Arizona based recycled aggregates business in our Construction Products segment. The purchase prices of these acquisitions were not significant. Divestitures On August 1, 2024, the Company entered into an agreement to sell its steel components business. The steel components business, reported in the Transportation Products segment, is a leading supplier of railcar coupling devices, railcar axles, and circular forgings. The transaction is expected to close during the third quarter. During the three months ended June 30, 2024, we completed the divestiture of certain assets and liabilities of a single-location asphalt and paving operation in our Construction Products segment and the sale of a non-operating facility in our Engineered Structures segment. The total consideration for these divestitures is expected to be approximately $137.3 million. For the divestitures that closed during the three months ended June 30, 2024, the Company recognized a pre-tax gain of $12.5 million which is reflected in gain on sale of businesses on the Consolidated Statement of Operations. There were no divestitures completed during the three and six months ended June 30, 2023. Other In June 2023, the Company settled a $15.0 million holdback obligation from the 2021 acquisition of Southwest Rock Products, LLC upon the extension of a certain mineral reserve lease. Based on final negotiations with the seller, the holdback was settled for $10.0 million and paid during the three months ended June 30, 2023. The $5.0 million difference between the settlement amount and the amount accrued at the time of acquisition was recorded as a reduction in cost of revenues in the Consolidated Statement of Operations.

Revolving Credit Facility

The carrying value of borrowings under our revolving credit approximates fair value because the interest rate adjusts to the market interest rate (Level 3 input). See Note 3 Fair Value Accounting.

As of June 30, 2024, the Company had $2.1 million of unamortized debt issuance costs related to the revolving credit facility, which are included in other assets on the Consolidated Balance Sheet.

Senior Notes

The estimated fair value of the Notes as of June 30, 2024 was $370.3 million based on a quoted market price in a market with little activity (Level 2 input).

In connection with the issuance of the Notes, the Company paid $6.6 million of debt issuance costs.

Income Taxes	Income Taxes For interim income tax reporting, we estimate our annual effective tax rate and apply it to our year-to-date ordinary income (loss). Tax jurisdictions with a projected or year to date loss for which a tax benefit cannot be realized are excluded. The tax effects of unusual or infrequently occurring items, including changes in judgment about valuation allowances and effects of changes in tax laws or rates, are reported in the interim period in which they occur. We have open tax years from 2014 to 2023 with various significant tax jurisdictions. Our effective tax rates of 14.3% and 15.6% for the three and six months ended June 30, 2024, respectively, differed from the U.S. federal statutory rate of 21.0% due to Advanced Manufacturing Production ("AMP") tax credits, compensation-related items, state income taxes, statutory depletion deductions, and tax effects of foreign currency translations. Our effective tax rates of 12.0% and 17.0% for the three and six months ended June 30, 2023, respectively, differed from the U.S. federal statutory rate of 21.0% due to AMP tax credits, tax effects of foreign currency translations, compensation-related items, state income taxes, and statutory depletion deductions.

Contingencies	Note 15. Contingencies The Company is involved in claims and lawsuits incidental to our business arising from various matters including commercial disputes, alleged product defect and/or warranty claims, intellectual property matters, personal injury claims, environmental issues, employment and/or workplace-related matters, and various governmental and environmental regulations. The Company evaluates its exposure to such claims and suits periodically and establishes accruals for these contingencies when probable losses can be reasonably estimated. At June 30, 2024, the reasonably possible losses and any related accruals for such matters were not significant. Estimates of liability arising from future proceedings, assessments, or remediation are inherently imprecise. Accordingly, there can be no assurance that we will not become involved in future litigation or other proceedings, including those related to the environment or, if we are found to be responsible or liable in any such litigation or proceeding, that such costs would not be material to the Company.

Cash and Cash Equivalents

Financial Instruments

The Company considers all highly liquid debt instruments to be cash and cash equivalents if purchased with a maturity of three months or less.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to a concentration of credit risk are primarily cash investments and receivables. The Company places its cash investments in bank deposits and highly-rated money market funds, and its investment policy limits the amount of credit exposure to any one commercial issuer. We seek to limit concentrations of credit risk with respect to receivables with control procedures that monitor the credit worthiness of customers, together with the large number of customers in the Company's customer base and their dispersion across different industries and geographic areas. As receivables are generally unsecured, the Company maintains an allowance for doubtful accounts based upon the expected credit losses. Receivable balances determined to be uncollectible are charged against the allowance. To accelerate the conversion to cash, the Company may sell a portion of its trade receivables to third parties. The Company has no recourse to these receivables once they are sold but may have continuing involvement related to servicing and collection activities. The impact of these transactions in the Company's Consolidated Statements of Operations for the three and six months ended June 30, 2024 was not significant. The carrying values of cash, receivables, and accounts payable are considered to be representative of their respective fair values.
