NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
UNAUDITED
(1)Basis of Presentation
The Condensed Consolidated Financial Statements do not include footnotes and certain financial information normally presented annually under generally accepted accounting principles in the United States (“GAAP”). Therefore, they should be read in conjunction with the audited consolidated financial statements and the related notes included in Tutor Perini Corporation’s (the “Company”) Annual Report on Form 10-K for the year ended December 31, 2023. The results of operations for the three and nine months ended September 30, 2024 may not be indicative of the results that will be achieved for the full year ending December 31, 2024.
In the opinion of management, the accompanying unaudited Condensed Consolidated Financial Statements reflect all adjustments, including those of a normal recurring nature, necessary to present fairly the Company’s consolidated financial position as of September 30, 2024 and its consolidated statements of operations and cash flows for the interim periods presented. Intercompany balances and transactions have been eliminated. Certain amounts in the condensed consolidated financial statements and notes thereto of prior years have been reclassified to conform to the current year presentation.
(2)Recent Accounting Pronouncements
In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07, Segment Reporting (“Topic 280”): Improvements to Reportable Segment Disclosures (“ASU 2023-07”), which requires disclosure of incremental segment information on an interim and annual basis. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, and requires retrospective application to all prior periods presented in the financial statements. Early adoption is permitted. The Company does not anticipate that the adoption of this ASU will have a material impact on its consolidated financial statements.
In December 2023, the FASB issued ASU 2023-09, Income Taxes (“Topic 740”): Improvements to Income Tax Disclosures (“ASU 2023-09”), which requires public entities to disclose specific categories in its annual effective tax rate reconciliation and disaggregated information about significant reconciling items by jurisdiction and by nature. ASU 2023-09 also requires entities to disclose their income tax payments (net of refunds) to international, federal, and state and local jurisdictions.

(a)The three and nine-month periods ended September 30, 2024 include the negative impact of a $101.6 million adjustment related to an adverse arbitration ruling on a completed Civil segment bridge project in California, of which $79.4 million was a reversal of previously recognized revenue. Refer to Note 18, Business Segments, for additional details.
(b)The nine-month period ended September 30, 2023 includes the negative impact of a non-cash charge of $83.6 million that resulted from an adverse legal ruling (of which $72.2 million impacted the Building segment and $11.4 million impacted the Specialty Contractors segment). Refer to Note 18, Business Segments, for additional details.
Changes in Contract Estimates that Impact Revenue
Changes to the total estimated contract revenue or cost for a given project, either due to unexpected events or revisions to management’s initial estimates, are recognized in the period in which they are determine d. Revenue was negatively impacted during the three and nine months ended September 30, 2024 related to performance obligations satisfied (or partially satisfied) in prior periods by $163.5 million and $180.4 million, respectively. Revenue was negatively impacted during the three and nine months ended September 30, 2023 related to performance obligations satisfied (or partially satisfied) in prior periods by $55.3 million and $167.4 million, respectively. Refe r to Note 18, Business Segments, for additional details on significant adjustments.
Remaining Performance Obligations
Remaining performance obligations represent the transaction price of firm orders for which work has not been performed and exclude unexercised contract options. As of September 30, 2024, the aggregate amounts of the transaction prices allocated to the remaining performance obligations of the Company’s construction contracts we re $4.1 billion, $3.2 billion and $1.3 billion for the Civil, Building and Specialty Contractors segments, respectively. As of September 30, 2023, the aggregate amounts of the transaction prices allocated to the remaining performance obligations of the Company’s construction contracts were $4.5 billion, $2.3 billion and $1.1 billion f or the Civil, Building and Specialty Contractors segments, respectively. The Company typically recognizes revenue on Civil segment projects over a period of three to five years, whereas for projects in the Building and Specialty Contractors segments, the Company typically recognizes revenue over a period of one to three years.

(4)Contract Assets and Liabilities
The Company classifies contract assets and liabilities that may be settled beyond one year from the balance sheet date as current, consistent with the length of time of the Company’s project operating cycle.
Contract assets include amounts due under retention provisions, costs and estimated earnings in excess of billings and capitalized contract costs. The amounts as included on the Condensed Consolidated Balance Sheets consisted of the following:

(in thousands) |  | As of September 30, 2024 |  | As of December 31, 2023
Retention receivable |  | $ | 549,736 |  |  | $ | 580,926 |
Costs and estimated earnings in excess of billings: |  |  |  |
Claims |  | 411,026 |  |  | 562,646 |
Unapproved change orders |  | 461,825 |  |  | 512,831 |
Other unbilled costs and profits |  | 93,400 |  |  | 68,369 |
Total costs and estimated earnings in excess of billings |  | 966,251 |  |  | 1,143,846 |
Capitalized contract costs |  | 93,118 |  |  | 117,913 |
Total contract assets |  | $ | 1,609,105 |  |  | $ | 1,842,685 |

Retention receivable represents amounts invoiced to customers where payments have been partially withheld pending the completion of certain milestones, satisfaction of other contractual conditions or the completion of the project. Retention agreements vary from project to project, and balances could be outstanding for several months or years depending on a number of circumstances such as contract-specific terms, project performance and other variables that may arise as the Company makes progress toward completion.
Costs and estimated earnings in excess of billings represent the excess of contract costs and profits (or contract revenue) over the amount of contract billings to date and are classified as a current asset. Costs and estimated earnings in excess of billings result when either: (1) the appropriate contract revenue amount has been recognized over time in accordance with Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers (“ASC 606”), but a portion of the revenue recorded cannot be billed currently due to the billing terms defined in the contract, or (2) costs are incurred related to certain claims and unapproved change orders. Claims occur when there is a dispute regarding both a change in the scope of work and the price associated with that change. Unapproved change orders occur when a change in the scope of work results in additional work being performed before the parties have agreed on the corresponding change in the contract price. The Company routinely estimates recovery related to claims and unapproved change orders as a form of variable consideration at the most likely amount it expects to receive and to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Claims and unapproved change orders are billable upon the agreement and resolution between the contractual parties and after the execution of contractual amendments. Increases in claims and unapproved change orders typically result from costs being incurred against existing or new positions; decreases normally result from resolutions and subsequent billings. As discussed in Note 11, Commitments and Contingencies, the resolution of these claims and unapproved change orders may require litigation or other forms of dispute resolution proceedings. Other unbilled costs and profits are billable in accordance with the billing terms of each of the existing contractual arrangements and, as such, the timing of contract billing cycles can cause fluctuations in the balance of unbilled costs and profits. Ultimate resolution of other unbilled costs and profits typically involves incremental progress toward contractual requirements or milestones. The amount of costs and estimated earnings in excess of billings as of September 30, 2024 estimated by management to be collected beyond one year is approximately $515.7 million.
Capitalized contract costs are included in other current assets and primarily represent costs to fulfill a contract that (1) directly relate to an existing or anticipated contract, (2) generate or enhance resources that will be used in satisfying performance obligations in the future and (3) are expected to be recovered through the contract. Capitalized contract costs are generally e xpense d to the associated contract over the period of anticipated use on the project. During the three and nine months ended September 30, 2024, $15.1 million and $47.0 million, respectively, of previously capitalized contract costs were amortized and recognized as expense on the related contracts. During the three and nine months ended September 30, 2023, $14.7 million and $34.5 million, respectively, of previously capitalized contract costs were amortized and recognized as expense on the related contracts.

Contract liabilities include amounts owed under retention provisions and billings in excess of costs and estimated earnings. The amount as reported on the Condensed Consolidated Balance Sheets consisted of the following:

(in thousands) |  | As of September 30, 2024 |  | As of December 31, 2023
Retention payable |  | $ | 226,033 |  |  | $ | 223,138 |
Billings in excess of costs and estimated earnings |  | 1,052,007 |  |  | 1,103,530 |
Total contract liabilities |  | $ | 1,278,040 |  |  | $ | 1,326,668 |

Retention payable represents amounts invoiced to the Company by subcontractors where payments have been partially withheld pending the completion of certain milestones, other contractual conditions or upon the completion of the project. Generally, retention payable is not remitted to subcontractors until the associated retention receivable from customers is collected.
Billings in excess of costs and estimated earnings represent the excess of contract billings to date over the amount of contract costs and profits (or contract revenue) recognized to date. The balance may fluctuate depending on the timing of contract billings and the recognition of contract revenue. Revenue recognized during the three and nine months ended September 30, 2024 and included in the opening billings in excess of costs and estimated earnings balances for each period totale d $534.2 million and $891.4 million, respectively. Revenue recognized during the three and nine months ended September 30, 2023 and included in the opening billings in excess of costs and estimated earnings balances for each period totaled $439.8 million and $663.6 million, respectively.
(5)Cash, Cash Equivalents and Restricted Cash
The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the Condensed Consolidated Balance Sheets to the amounts shown in the Condensed Consolidated Statements of Cash Flows:

(in thousands) |  | As of September 30, 2024 |  | As of December 31, 2023
Cash and cash equivalents available for general corporate purposes |  | $ | 118,433 |  |  | $ | 145,055 |
Joint venture cash and cash equivalents |  | 168,970 |  |  | 235,509 |
Cash and cash equivalents |  | 287,403 |  |  | 380,564 |
Restricted cash |  | 13,994 |  |  | 14,116 |
Total cash, cash equivalents and restricted cash |  | $ | 301,397 |  |  | $ | 394,680 |

Cash equivalents include short-term, highly liquid investments with maturities of three months or less when acquired. Cash and cash equivalents consist of amounts available for the Company’s general purposes, the Company’s proportionate share of cash held by the Company’s unconsolidated joint ventures and 100% of amounts held by the Company’s consolidated joint ventures. In both cases, cash held by joint ventures is available only for joint venture-related uses, including future distributions to joint venture partners.
Restricted cash includes amounts primarily held as collateral to secure insurance-related contingent obligations, such as insurance claim deductibles, in lieu of letters of credit.
(6)Earnings Per Common Share
Basic earnings per common share (“EPS”) and diluted EPS are calculated by dividing net income (loss) attributable to Tutor Perini Corporation by the following: for basic EPS, the weighted-average number of common shares outstanding during the period; and for diluted EPS, the sum of the weighted-average number of both outstanding common shares and potentially dilutive securities, which for the Company can include restricted stock units (“RSUs”) and unexercised stock options. The Company calculates the effect of the potentially dilutive RSUs and stock options using the treasury stock method.

For the three and nine months ended September 30, 2024 and 2023, all outstanding RSUs and stock options were excluded from the calculation of weighted-average diluted shares outstanding, as the shares have an anti-dilutive effect due to the net loss for the periods.
(7)Income Taxes
The Company recognized an income tax benefit of $33.9 million and $19.4 million for the three and nine months ended September 30, 2024, respectively. The effective income tax rate was 27.5% and 29.6% for the three and nine months ended September 30, 2024, respectively. The effective income tax rates for both periods were impacted by relatively large tax benefits generated against a forecasted pre-tax loss for the year, which magnified the impact these tax benefits had on the effective income tax rate. In periods with pre-tax losses, tax benefits generated during the period increase the effective income tax rate (and, thus, the income tax benefit to the Company) rather than decreasing the effective rate, as in periods with pre-tax income. The effective income tax rate for both the three and nine months ended September 30, 2024 was higher than the 21.0% federal statutory income tax rate primarily due to earnings attributable to noncontrolling interests (for which income taxes are not the responsibility of the Company) and state income taxes (net of the federal tax benefit), partially offset by non-deductible expenses.
The Company rec ognized an income tax benefit of $4.1 million and $52.0 million for the three and nine months ended September 30, 2023, respectively. The effective income tax rate was 13.7% and 36.2% for the three and nine months ended September 30, 2023, respectively. The effective income tax rate for the three months ended September 30, 2023 was lower than the 21.0% federal statutory rate primarily due to the impact of a cumulative catch-up adjustment associated with the change in the Company’s projected 2023 effective tax rate that resulted from the revision of the Company’s forecast. The effective income tax rates for both periods were impacted by relatively large tax benefits generated against a forecasted pre-tax loss for the year, which magnified the impact these tax benefits had on the effective income tax rate. In periods with pre-tax losses, tax benefits generated during the period increase the effective income tax rate (and, thus, the income tax benefit to the Company) rather than decreasing the effective rate, as in periods with pre-tax income. The tax benefits that caused a higher effective tax rate were primarily state income taxes (net of the federal tax benefit), earnings attributable to noncontrolling interests (for which income taxes are not the responsibility of the Company) and a reduction in reserves for unrecognized tax benefits, partially offset by non-deductible expenses.

The Company performed its annual impairment test in the fourth quarter of 2023 and concluded goodwill was not impaired. In addition, the Company determined that no triggering events occurred and no circumstances changed since the date of its annual impairment test that would more likely than not reduce the fair value of the Civil reporting unit below its carrying amount.
The Company will continue to monitor events and circumstances for changes that indicate the Civil reporting unit goodwill would need to be reevaluated for impairment during future interim periods prior to the annual impairment test. These future events and circumstances include, but are not limited to, changes in the overall financial performance of the Civil reporting unit, as well as other quantitative and qualitative factors which could indicate potential triggering events for possible impairment.

Amortization expense related to amortizable intangible assets for each of the three and nine months ended September 30, 2024 and 2023 was $0.6 million and $1.7 million, respectively. As of September 30, 2024, future amortization expense related to amortizable intangible assets will be approximately $0.6 million for the remainder of 2024, $2.2 million per year for the years 2025 through 2029 and $4.6 million thereafter.
The Company performed its annual impairment test for non-amortizable trade names during the fourth quarter of 2023. Based on this assessment, the Company concluded that its non-amortizable trade names were not impaired. In addition, the Company determined that no triggering events occurred and no circumstances changed since the date of its annual impairment test that would indicate impairment of its non-amortizable trade names. Other amortizable intangible assets are reviewed for impairment whenever circumstances indicate that the future cash flows generated by the assets might be less than the assets’ net carrying value. The Company had no impairment of intangible assets during the three and nine months ended September 30, 2024 or 2023.

2024 Senior Notes
On April 22, 2024, the Company issued $400.0 million in aggregate principal amount of 11.875% Senior Notes due April 30, 2029 (the “2024 Senior Notes”) in a private placement offering. Interest on the 2024 Senior Notes is payable in arrears semi-annually in April and October of each year, beginning in October 2024. The proceeds from the 2024 Senior Notes were used to redeem the 2017 Senior Notes (as discussed below).

Prior to April 30, 2026, the Company may redeem the 2024 Senior Notes at a redemption price equal to 100% of the principal amount plus a “make-whole” premium described in the indenture. In addition, prior to April 30, 2026, the Company may redeem up to 40% of the original aggregate principal amount of the 2024 Senior Notes at a redemption price of 111.875% of their principal amount with the “net cash proceeds” received by the Company from one or more equity offerings, as described in the indenture. On or after April 30, 2026, the Company may redeem the 2024 Senior Notes at specified redemption prices described in the indenture. If the Company experiences certain change of control events, holders of the 2024 Senior Notes may require the Company to repurchase all or part of the 2024 Senior Notes at 101% of the principal amount thereof, plus accrued and unpaid interest to the redemption date.
The 2024 Senior Notes are senior unsecured obligations of the Company and are guaranteed by the Company’s existing and future subsidiaries that also guarantee obligations under the Company’s 2020 Credit Agreement. In addition, the indenture for the 2024 Senior Notes provides for customary covenants, including restrictions on the payment of dividends and share repurchases, and includes customary events of default.
Redemption of 2017 Senior Notes
On April 20, 2017, the Company issued $500.0 million in aggregate principal amount of 6.875% Senior Notes due May 1, 2025 (the “2017 Senior Notes”) in a private placement offering.
The proceeds of the 2024 Senior Notes, together with cash on hand, were used to redeem in full, all of the outstanding obligations in respect of the 2017 Senior Notes. The redemption of the 2017 Senior Notes occurred on May 2, 2024 (the “2017 Senior Notes Redemption”).
2020 Credit Agreement
On August 18, 2020, the Company entered into a credit agreement (as amended, the “2020 Credit Agreement”) with BMO Bank N.A. (f/k/a BMO Harris Bank N.A.), as Administrative Agent, Swing Line Lender and L/C Issuer and other lenders. The 2020 Credit Agreement originally provided for a $425.0 million term loan B facility (the “Term Loan B”) and a $175.0 million revolving credit facility (the “Revolver”), which was subsequently reduced to $170.0 million following the effectiveness of the 2024 Amendment (as defined and discussed below), with sub-limits for the issuance of letters of credit and swing line loans up to the aggregate amounts of $75.0 million and $10.0 million, respectively. The Term Loan B will mature on August 18, 2027. Prior to the 2017 Senior Notes Redemption, if any of the 2017 Senior Notes had remained outstanding beyond certain dates, the maturities of the Term Loan B and the Revolver would have been subject to acceleration (“spring-forward maturity”). However, following the 2017 Senior Notes Redemption and the consummation of the 2024 Amendment, the spring-forward maturity of the Term Loan B is no longer in effect and the spring-forward maturity of the Revolver has been extended (as described below).
On April 15, 2024, the Company entered into an amendment in respect of the 2020 Credit Agreement (the “2024 Amendment”) which, among other changes, (1) extends the existing Revolver maturity date from August 18, 2025 to (a) if any tranche of the Term Loan B, any incremental term loan or any refinancing term loan (or any refinancing or replacement thereof) remains outstanding, the earlier of (i) May 20, 2027 and (ii) the date that is ninety (90) days prior to the final maturity of any tranche of the Term Loan B, any incremental term loan or any refinancing term loan (or any refinancing or replacement thereof), as applicable, and (b) if no obligations are outstanding with respect to any tranche of the Term Loan B, any incremental term loan or any refinancing term loan, August 18, 2027 and (2) permanently reduces the aggregate commitments in respect of the Revolver by $5.0 million from $175.0 million to $170.0 million. The 2024 Amendment became effective on May 2, 2024 upon the completion of the 2017 Senior Notes Redemption.
The 2020 Credit Agreement permits the Company to repay any or all borrowings outstanding under the 2020 Credit Agreement at any time prior to maturity without penalty. The 2020 Credit Agreement requires the Company to make regularly scheduled payments of principal on the Term Loan B in quarterly installments equal to 0.25% of the initial principal amount of the Term Loan B. The 2020 Credit Agreement also requires the Company to make prepayments on the Term Loan B in connection with certain asset sales, receipts of insurance proceeds, incurrences of certain indebtedness and annual excess cash flow (in each case, subject to certain customary exceptions). At December 31, 2023, current maturities of long-term debt in the accompanying Condensed Consolidated Balance Sheet included $91.0 million prepayment of principal on the Term Loan B, relating to the mandatory prepayment provision of the 2020 Credit Agreement in respect of annual excess cash flow. The $91.0 million prepayment included in current maturities at December 31, 2023, which was due by the first week of April 2024, was paid in February 2024.

Subject to certain exceptions, at any time prior to maturity, the 2020 Credit Agreement provides the Company with the right to increase the commitments under the Revolver and/or to establish one or more term loan facilities in an aggregate amount up to (i) the greater of $173.5 million and 50% LTM EBITDA (as defined in the 2020 Credit Agreement) plus (ii) additional amounts if (A) in the case of pari passu first lien secured indebtedness, the First Lien Net Leverage Ratio (as defined in the 2020 Credit Agreement) does not exceed 1.35:1.00, (B) in the case of junior lien secured indebtedness, the Total Net Leverage Ratio (as defined in the 2020 Credit Agreement) does not exceed 3.50:1.00 and (C) in the case of unsecured indebtedness, (x) the Total Net Leverage Ratio does not exceed 3.50:1.00 or (y) the Fixed Charge Coverage Ratio (as defined in the 2020 Credit Agreement) is no less than 2.00:1.00.
Borrowings under the 2020 Credit Agreement bear interest, at the Company’s option, at a rate equal to (i) (A) in the case of the Term Loan B, following the amendment to the 2020 Credit Agreement on May 2, 2023 (as discussed below), (x) the Adjusted Term Secured Overnight Financing Rate (“Adjusted Term SOFR”) (calculated with a 11.448 basis point, 26.161 basis point and 42.826 basis point credit spread adjustment for a 1, 3 and 6 month interest period, respectively) or (y) a base rate (determined by reference to the highest of (1) the administrative agent’s prime lending rate, (2) the federal funds effective rate plus 50 basis points and (3) the Adjusted Term SOFR rate for a one-month interest period plus 100 basis points) and (B) in case of the Revolver, following the amendment to the 2020 Credit Agreement on October 31, 2022 (as discussed below), (x) the Adjusted Term SOFR rate (calculated with a 10 basis point credit spread adjustment for all interest periods) or (y) a base rate (determined by reference to the highest of (1) the administrative agent’s prime lending rate, (2) the federal funds effective rate plus 50 basis points and (3) the Adjusted Term SOFR rate for a one-month interest period plus 100 basis points) plus, in each case, (ii) an applicable margin. The margin applicable to the Term Loan B is between 4.50% and 4.75% for Adjusted Term SOFR and between 3.50% and 3.75% for base rate, and, in each case, is based on the Total Net Leverage Ratio. The margin applicable to the Revolver is between 4.25% and 4.75% for Adjusted Term SOFR and 3.25% and 3.75% for base rate, and, in each case, is based on the First Lien Net Leverage Ratio. Effective following the amendment to the 2020 Credit Agreement on October 31, 2022, the Company’s original London Interbank Offered Rate (“LIBOR”) option in respect of the Revolver was transitioned to Adjusted Term SOFR. Effective May 2, 2023, the 2020 Credit Agreement was further amended to transition the Company’s original LIBOR option in respect of the Term Loan B to Adjusted Term SOFR. In addition to paying interest on outstanding principal under the 2020 Credit Agreement, the Company will pay a commitment fee to the lenders under the Revolver in respect of the unutilized commitments thereunder. The Company will pay customary letter of credit fees. If a payment or bankruptcy event of default occurs and is continuing, the otherwise applicable margin on overdue amounts will be increased by 2% per annum. The 2020 Credit Agreement includes customary provisions for the replacement of Adjusted Term SOFR with an alternative benchmark rate upon Adjusted Term SOFR being discontinued. The weighted-average annual interest rate on borrowings under the Revolver w as 12.0% durin g the nine months ended September 30, 2024.
The 2020 Credit Agreement requires, solely with respect to the Revolver, the Company and its restricted subsidiaries to maintain a maximum First Lien Net Leverage Ratio of 3.50:1.00, effective the fiscal quarter ended December 31, 2022 and increasing to 3.75:1.00 for the fiscal quarter ending March 31, 2023 and subsequently stepping down to 3.00:1.00 for the fiscal quarter ending June 30, 2023, 2.50:1.00 for the fiscal quarter ending September 30, 2023 and 2.25:1.00 for the fiscal quarter ending December 31, 2023 and each fiscal quarter thereafter. The 2020 Credit Agreement also includes certain customary representations and warranties, affirmative covenants and events of default. Subject to certain exceptions, substantially all of the Company’s existing and future material wholly-owned subsidiaries unconditionally guarantee the obligations of the Company under the 2020 Credit Agreement; additionally, subject to certain exceptions, the obligations are secured by a lien on substantially all of the assets of the Company and its subsidiaries guaranteeing these obligations.
As of September 30, 2024, the entire $170.0 million was available under the Revolver. The Company was in compliance with the financial covenant under the 2020 Credit Agreement for the period ended September 30, 2024.

(11)Commitments and Contingencies
The Company and certain of its subsidiaries are involved in litigation and other legal proceedings and forms of dispute resolution in the ordinary course of business, including but not limited to disputes over contract payment and/or performance-related issues (such as disagreements regarding delay or a change in the scope of work of a project and/or the price associated with that change) and other matters incidental to the Company’s business. In accordance with ASC 606, the Company makes assessments of these types of matters on a routine basis and, to the extent permitted by ASC 606, estimates and records recovery related to these matters as a form of variable consideration at the most likely amount the Company expects to receive, as discussed further in Note 4, Contract Assets and Liabilities. In addition, the Company is contingently liable for litigation, performance guarantees and other commitments arising in the ordinary course of business, which are accounted for in accordance with ASC 450, Contingencies. Management reviews these matters regularly and updates or revises its estimates as warranted by subsequent information and developments. These assessments require judgments concerning matters that are inherently uncertain, such as litigation developments and outcomes, the anticipated outcome of negotiations and the estimated

cost of resolving disputes. Consequently, these assessments are estimates, and actual amounts may vary from such estimates. In addition, because such matters are typically resolved over long periods of time, the Company’s assets and liabilities may change over time should the circumstances dictate. The description of the legal proceedings listed below include management’s assessment of those proceedings. Management believes that, based on current information and discussions with the Company’s legal counsel, the ultimate resolution of other matters is not expected to have a material effect on the Company’s consolidated financial position, results of operations or cash flows.
A description of the material pending legal proceedings, other than ordinary routine litigation incidental to the business, is as follows:
Alaskan Way Viaduct Matter
In January 2011, Seattle Tunnel Partners (“STP”), a joint venture between Dragados USA, Inc. and the Company, entered into a design-build contract with the Washington State Department of Transportation (“WSDOT”) for the construction of a large-diameter bored tunnel in downtown Seattle, King County, Washington to replace the Alaskan Way Viaduct, also known as State Route 99. The Company has a 45% interest in STP.
The construction of the large-diameter bored tunnel required the use of a tunnel boring machine (“TBM”). In December 2013, the TBM struck a steel pipe, installed by WSDOT as a well casing for an exploratory well. The TBM was significantly damaged and was required to be repaired. STP asserted that the steel pipe casing was a differing site condition that WSDOT failed to properly disclose. The Disputes Review Board mandated by the contract to hear disputes issued a decision finding the steel casing was a Type I (material) differing site condition. WSDOT did not accept that finding.
The TBM was insured under a Builder’s Risk Insurance Policy (the “Policy”) with Great Lakes Reinsurance (UK) PLC and a consortium of other insurers (the “Insurers”). STP submitted the claims to the Insurers and requested interim payments under the Policy. The Insurers refused to pay and denied coverage. In June 2015, STP filed a lawsuit in the King County Superior Court, State of Washington seeking declaratory relief concerning contract interpretation, as well as damages as a result of the Insurers’ breach of their obligations under the terms of the Policy. STP also asserted extra-contractual and statutory claims against the Insurers.
In April and September 2018, rulings received on pre-trial motions limited some of the potential recoveries under the Policy for STP, WSDOT and Hitachi. On August 2, 2021, the Court of Appeals reversed in part certain of those limitations but affirmed other parts of those rulings. On September 15, 2022, the Washington Supreme Court affirmed the decision of the Court of Appeals, which limited recovery of certain damages under the Policy. Based on the rulings of the Court of Appeals, the case was continued for adjudication on the remaining facts and legal issues, including the number of covered occurrences which could increase the amount of available coverage under the Policy and the amount of investigative costs that are subject to the Policy limits. STP advanced damages to the Insurers in the King County lawsuit in the amount of $145.5 million, plus $152.8 million in interest, plus attorney fees and costs, plus STP’s supplier, Hitachi Zosen (“Hitachi”), the manufacturer of the TBM, sought $70.0 million in insurance proceeds. On September 30, 2024, a confidential settlement was reached resolving the case in full for a substantial sum. Payment was received in October 2024 and the case was dismissed.
In addition, STP has a pending case in the Washington Superior Court against HNTB Corporation (“HNTB”), STP’s design firm on the project, wherein STP alleges that HNTB is liable for providing design services that resulted in the TBM striking the steel pipe described above and for additional steel quantity costs associated with the project. Due to the resolution of the matter against the Insurers discussed above, STP’s current complaint against HNTB seeking in excess of $640 million is expected to be reduced to reflect only the remaining damages being sought. The case is scheduled for trial to commence on July 14, 2025. With respect to STP’s claims against HNTB, management has included in receivables an estimate of the total anticipated recovery concluded to be probable.
In March 2016, WSDOT filed a complaint against STP in Thurston County Superior Court alleging breach of contract, seeking $57.2 million in delay-related damages and seeking declaratory relief concerning contract interpretation. STP subsequently filed a counterclaim against WSDOT seeking the same damages in excess of $640 million. The jury trial between STP and WSDOT commenced on October 7, 2019 and concluded on December 13, 2019, with a jury verdict in favor of WSDOT awarding them $57.2 million in damages. The Company recorded the impact of the jury verdict during the fourth quarter of 2019, resulting in a pre-tax charge of $166.8 million, which included $25.7 million for the Company’s 45% proportionate share of the $57.2 million in damages awarded by the jury to WSDOT. The charge was for non-cash write-downs primarily related to the costs and

estimated earnings in excess of billings and receivables that the Company previously recorded to reflect its expected recovery in this case.
STP filed a petition for discretionary review by the Washington Supreme Court on July 12, 2022, which was denied by the Supreme Court on October 10, 2022. On October 18, 2022, STP paid the damages and associated interest from the judgment, which included the Company’s proportionate share of $34.6 million. As a result, the lawsuit between STP and WSDOT has concluded.

The unrealized losses in AFS debt securities as of September 30, 2024 and December 31, 2023 are primarily attributable to market interest rate increases and not a deterioration in credit quality of the issuers. Management evaluated the unrealized losses in AFS debt securities considering factors including credit ratings and other relevant information, which may indicate that contractual cash flows are not expected to occur. Based on the analysis, management determined that credit losses did not exist for AFS debt securities in an unrealized loss position as of September 30, 2024 and December 31, 2023.
It is not considered likely that the Company will be required to sell the investments before full recovery of the amortized cost basis of the AFS debt securities, which may be at maturity. As a result, consistent with the same period in 2023, the Company has not recognized any impairment losses in earnings during the nine months ended September 30, 2024.

The amortized cost and fair value of AFS debt securities by contractual maturity as of September 30, 2024 are summarized in the table below. Actual maturities may differ from contractual maturities because certain borrowers have the right to call or prepay certain obligations.

(in thousands) | Amortized Cost | Fair Value
Due within one year | $ | 73,458 |  | $ | 72,601 |
Due after one year through five years | 149,868 |  | 151,220 |

Total | $ | 233,488 |  | $ | 233,326 |

The carrying values of receivables, payables and other amounts arising out of normal contract activities, including retention, which may be settled beyond one year, are estimated to approximate fair value. Of the Company’s long-term debt, the fair value of the 2024 Senior Notes was $447.0 million as of September 30, 2024 and the fair value of the 2017 Senior Notes was $490.9 million as of December 31, 2023. The fair values of the 2024 Senior Notes and 2017 Senior Notes were determined using Level 1 inputs, specifically current observable market prices. The fair value of the Term Loan B was $272.2 million and $358.9 million as of September 30, 2024 and December 31, 2023, respectively. The fair values of the Term Loan B were determined using Level 2 inputs, specifically third-party quoted market prices. The reported value of the Company’s remaining borrowings approximates fair value as of September 30, 2024 and December 31, 2023.
(15)Variable Interest Entities (VIEs)
The Company may form joint ventures or partnerships with third parties for the execution of projects. In accordance with ASC 810, Consolidation (“ASC 810”), the Company assesses its partnerships and joint ventures at inception to determine if any meet the qualifications of a VIE. The Company considers a joint venture a VIE if either (a) the total equity investment is not sufficient to permit the entity to finance its activities without additional subordinated financial support, (b) characteristics of a controlling financial interest are missing (either the ability to make decisions through voting or other rights, the obligation to absorb the expected losses of the entity or the right to receive the expected residual returns of the entity), or (c) the voting rights of the equity holders are not proportional to their obligations to absorb the expected losses of the entity and/or their rights to receive the expected residual returns of the entity, and substantially all of the entity’s activities either involve or are conducted on behalf of an investor that has disproportionately few voting rights. Upon the occurrence of certain events outlined in ASC 810, the Company reassesses its initial determination of whether a joint venture is a VIE.
ASC 810 also requires the Company to determine whether it is the primary beneficiary of the VIE. The Company concludes that it is the primary beneficiary and consolidates the VIE if the Company has both (a) the power to direct the economically significant activities of the VIE and (b) the obligation to absorb losses of, or the right to receive benefits from, the VIE that could potentially be significant to the VIE. The Company considers the contractual agreements that define the ownership structure, distribution of profits and losses, risks, responsibilities, indebtedness, voting rights and board representation of the respective parties in determining if the Company is the primary beneficiary. The Company also considers all parties that have direct or implicit variable interests when determining whether it is the primary beneficiary. In accordance with ASC 810, management’s assessment of whether the Company is the primary beneficiary of a VIE is performed continuously.
As of September 30, 2024, the Company had unconsolidated VIE-related current assets and liabilities of $3.5 million and $0.1 million, respectively, included in the Company’s Condensed Consolidated Balance Sheets. As of December 31, 2023, the Company had unconsolidated VIE-related current assets and liabilities of $0.5 million and $0.1 million, respectively, included in the Company’s Condensed Consolidated Balance Sheets. The Company’s maximum exposure to loss as a result of its investments in unconsolidated VIEs is typically limited to the aggregate of the carrying value of the investment and future funding commitments. There were no future funding requirements for the unconsolidated VIEs as of September 30, 2024.
As of September 30, 2024, the Company’s Condensed Consolidated Balance Sheets included current and noncurrent assets of $506.5 million and $25.5 million, respectively, as well as current liabilities of $432.4 million related to the operations of its consolidated VIEs. As of December 31, 2023, the Company’s Condensed Consolidated Balance Sheets included current and noncurrent assets of $503.1 million and $35.1 million, respectively, as well as current liabilities of $505.0 million related to the operations of its consolidated VIEs.

Below is a discussion of some of the Company’s more significant or unique VIEs.
The Company established a joint venture to construct the Purple Line Extension Section 2 (Tunnels and Stations) and Section 3 (Stations) mass-transit projects in Los Angeles, California with an original combined value of approximately $2.8 billion. The Company has a 75% interest in the joint venture with the remaining 25% held by O&G Industries, Inc. The joint venture was initially financed with contributions from the partners and, per the terms of the joint venture agreement, the partners may be required to provide additional capital contributions in the future. The Company has determined that this joint venture is a VIE for which the Company is the primary beneficiary.
The Company also established a joint venture with Parsons Corporation (“Parsons”) to construct the Newark Liberty International Airport Terminal One project, a transportation infrastructure project in Newark, New Jersey with an original value of approximately $1.4 billion. The Company has an 80% interest in the joint venture with the remaining 20% held by Parsons. The joint venture was initially financed with contributions from the partners and, per the terms of the joint venture agreement, the partners may be required to provide additional capital contributions in the future. The Company has determined that this joint venture is a VIE for which the Company is the primary beneficiary.

The Specialty Contractors segment specializes in electrical, mechanical, plumbing, HVAC and fire protection systems for a full range of civil and building construction projects in the industrial, commercial, hospitality and gaming, and mass-transit end markets. This segment provides the Company with unique strengths and capabilities that allow the Company to position itself as a full-service contractor with greater control over scheduled work, project delivery, and cost and risk management.
To the extent that a contract is co-managed and co-executed among segments, the Company allocates the share of revenues and costs of the contract to each segment to reflect the shared responsibilities in the management and execution of the project.
The following tables set forth certain reportable segment information relating to the Company’s operations for the three and nine months ended September 30, 2024 and 2023:

____________________________________________________________________________________________________
(a)During the three months ended September 30, 2024, the Company’s loss from construction operations was impacted by unfavorable adjustments of $101.6 million ($74.5 million after tax, or $1.42 per diluted share) related to an unexpected adverse arbitration decision on a legacy dispute related to a completed Civil segment bridge project in California, which the Company will appeal; $20.0 million ($14.7 million after tax, or $0.28 per diluted share) related to a settlement on a legacy dispute related to a completed Building segment government facility project in Florida; $17.7 million ($13.0 million after tax, or $0.25 per diluted share) due to an unfavorable judgment on a completed Specialty Contractors segment mass-transit project in California; and $11.5 million ($8.4 million after tax, or $0.16 per diluted share) due to an unfavorable arbitration ruling on a completed Specialty Contractors segment mass-transit project in New York. The period was also impacted by a favorable adjustment of $18.4 million ($13.5 million after tax, or $0.26 per diluted share) due to a settlement of a claim associated with a completed Civil segment highway tunneling project in the Western United States.
(b)Consists primarily of corporate general and administrative expenses. Corporate general and administrative expenses for the three months ended September 30, 2024 and 2023 included share-based compensation expense of $16.5 million ($12.1 million after tax, or $0.23 per diluted share) and $3.5 million ($2.5 million after tax, or $0.05 per diluted share), respectively. The increase in share-based compensation expense in the third quarter of 2024 was primarily due to a substantial increase in the Company’s stock price during the period, which impacted the fair value of liability-classified awards. These awards are remeasured at fair value at the end of each reporting period with the change recognized in earnings.
(c)Depreciation and amortization is included in income (loss) from construction operations.
(d)During the three months ended September 30, 2023, the Company’s income (loss) from construction operations was adversely impacted by $16.9 million ($12.3 million after tax, or $0.24 per diluted share) of unfavorable non-cash adjustments due to changes in estimates on the Specialty Contractors segment’s electrical and mechanical scope of a transportation project in the Northeast associated with changes in the expected recovery on certain unapproved change orders resulting from ongoing negotiations, $14.0 million ($10.9 million after tax, or $0.21 per diluted share) of

unfavorable adjustments on the same transportation project in the Northeast, split evenly between the Civil and Building segments, primarily due to the settlement of certain change orders, changes in estimates due to recent negotiations and incremental cost incurred during project closeout, and a $9.4 million ($6.8 million after tax, or $0.13 per diluted share) unfavorable adjustment due to ongoing negotiations and an anticipated settlement on a completed Specialty Contractors segment mass-transit project in California. During the third quarter of 2023, the Company reached a settlement that impacted multiple components of a Civil segment mass-transit project in California, which included the resolution of certain ongoing disputes and increased the expected profit from work to be performed in the future. The settlement resulted in an unfavorable non-cash adjustment of $23.2 million ($16.8 million after tax, or $0.32 per diluted share) to one component of the project that is nearing completion, partially offset by a favorable adjustment of $8.8 million ($7.0 million after tax, or $0.13 per diluted share) on the other component of the project that has substantial scope of work remaining. As a result of the settlement, the net unfavorable impact to the period from these two adjustments is expected to be mitigated by the increased profit generated from future work on the project.

(b)Consists primarily of corporate general and administrative expenses. Corporate general and administrative expenses for the nine months ended September 30, 2024 and 2023 included share-based compensation expense of $39.0 million ($28.6 million after tax, or $0.55 per diluted share) and $9.1 million ($6.6 million after tax, or $0.13 per diluted share),

respectively. The increase in share-based compensation expense in the current-year period was primarily due to a substantial increase in the Company’s stock price during the period, which impacted the fair value of liability-classified awards. These awards are remeasured at fair value at the end of each reporting period with the change recognized in earnings.
(c)Depreciation and amortization is included in income (loss) from construction operations.
(d)During the nine months ended September 30, 2023, the Company’s income (loss) from construction operations was impacted by an adverse legal ruling on a completed mixed-use project in New York, which resulted in a non-cash, pre-tax charge of $83.6 million ($60.1 million after tax, or $1.16 per diluted share) in the first quarter, of which $72.2 million impacted the Building segment and $11.4 million impacted the Specialty Contractors segment; $57.0 million ($41.4 million after tax, or $0.80 per diluted share) of unfavorable non-cash adjustments due to changes in estimates on the Specialty Contractors segment’s electrical and mechanical scope of a transportation project in the Northeast associated with changes in the expected recovery on certain unapproved change orders resulting from ongoing negotiations; $27.5 million ($21.4 million after tax, or $0.41 per diluted share) of unfavorable adjustments on the same transportation project in the Northeast, split evenly between the Civil and Building segments, primarily due to the settlement of certain change orders, changes in estimates due to recent negotiations and incremental cost incurred during project closeout; net favorable adjustments of $25.6 million ($20.3 million after tax, or $0.39 per diluted share) for a Civil segment mass-transit project in California that resulted from changes in estimates due to improved performance; a non-cash charge of $25.1 million ($18.2 million after tax, or $0.35 per diluted share) in the second quarter of 2023 that resulted from an adverse legal ruling on a Specialty Contractors segment educational facilities project in New York; and a $9.4 million ($6.8 million after tax, or $0.13 per diluted share) unfavorable adjustment in the third quarter due to ongoing negotiations and an anticipated settlement on a completed Specialty Contractors segment mass-transit project in California. During the third quarter of 2023, the Company reached a settlement that impacted multiple components of a Civil segment mass-transit project in California, which included the resolution of certain ongoing disputes and increased the expected profit from work to be performed in the future. The settlement resulted in an unfavorable non-cash adjustment of $23.2 million ($16.8 million after tax, or $0.32 per diluted share) to one component of the project that is nearing completion, partially offset by a favorable adjustment of $8.8 million ($7.0 million after tax, or $0.14 per diluted share) on the other component of the project that has substantial scope of work remaining. As a result of the settlement, the net unfavorable impact to the period from these two adjustments is expected to be mitigated by the increased profit generated from future work on the project.

Executive Overview
Operating Results
Consolidated revenue for the three months ended September 30, 2024 was $1.1 billion, up slightly compared to the same period in 2023. Consolidated revenue for the nine months ended September 30, 2024 was $3.3 billion, up 14% compared to the same period in 2023. For the nine-month period of 2024, the growth was primarily driven by increased project execution activities on certain Building segment projects, including various healthcare and educational facility projects in California and a detention facility project in New York. The growth was also due to increased project execution activities on various Civil segment projects, including certain mass-transit projects in California, two airport projects in the Northern Mariana Islands and the tunneling component of an energy project in British Columbia, as well as the absence of certain prior-year net unfavorable adjustments, as discussed in more detail below in Results of Segment Operations. The improvement for the nine-month period of 2024 was partially offset by reduced project execution activities on a Civil segment mass-transit project in the Midwest that is nearing completion, as well as certain net unfavorable adjustments in the current-year period, also discussed in more detail below.
Loss from construction operations for the three months ended September 30, 2024 was $106.8 million compared to $12.6 million for the same period in 2023. For the third quarter of 2024, the higher loss was primarily due to current-quarter unfavorable adjustments, including $101.6 million related to an unexpected adverse arbitration decision on a legacy dispute related to a completed Civil segment bridge project in California, which the Company will appeal; $20.0 million related to a settlement on a legacy dispute related to a completed Building segment government facility project in Florida; $17.7 million due to an unfavorable judgment on a completed Specialty Contractors segment mass-transit project in California; and $11.5 million due to an unfavorable arbitration ruling on a completed Specialty Contractors segment mass-transit project in New York. The higher loss was partially offset by contributions related to increased project execution activities in the Building and Civil segments, an $18.4 million favorable adjustment due to a settlement of a claim associated with a completed Civil segment highway tunneling project in the Western United States and the absence of certain prior-year net unfavorable adjustments, as discussed further below in Results of Segment Operations.
Loss from construction operations for the nine months ended September 30, 2024 was $17.5 million compared to $92.1 million for the same period in 2023. For the nine-month period of 2024, the improvement was primarily due to the absence of certain prior-year net unfavorable adjustments, as discussed further below in Results of Segment Operations, contributions totaling $78.5 million related to the increased project execution activities discussed above, and a favorable adjustment of $10.2 million in the first quarter of 2024 on a Civil segment mass-transit project in California related to a dispute resolution and associated expected cost savings. The improvement for the period was partially offset by the impact of the net unfavorable adjustments in the third quarter of 2024 discussed in the paragraph above, an unfavorable adjustment of $12.4 million in the second quarter of 2024 due to the impact of a settlement on two completed Civil segment highway projects in the Northeast, and an unfavorable adjustment of $12.0 million in the first quarter of 2024 due to an arbitration ruling that only provided a partial award to the Company pertaining to a completed Specialty Contractors segment electrical project in New York.
Furthermore, loss from construction operations for the three and nine months ended September 30, 2024 was negatively impacted by share-based compensation expense of $16.5 million and $39.0 million, respectively, compared to share-based compensation expense of $3.5 million and $9.1 million for the respective periods in 2023. The increase in share-based compensation expense in both 2024 periods was primarily due to a substantial increase in the Company’s stock price throughout the first three quarters of 2024, which impacted the fair value of liability-classified awards. These awards are remeasured at fair value at the end of each reporting period with the change recognized in earnings.

The Company generated strong cash from operations in the first nine months of 2024, and as a result of significant progress made in the resolution of various disputed matters, including those discussed above, and cash generation related to project execution activities for new and existing projects, it expects to generate cash flow from operations in the range of $250 million to $400 million in the fourth quarter of 2024 (and, consequently, $425 million to $575 million of anticipated cash flow from operations for the full year of 2024). Cash flow from operations anticipated for the fourth quarter is expected to be driven by collections of approximately $180 million related to the resolution of the above-mentioned third-quarter 2024 settlements, as well as cash generation related to project execution activities for new and existing projects. The wide range in the estimated generation of operating cash in the fourth quarter of 2024 is due to the uncertainty as to the precise timing of when certain large payments will be collected, though any amounts in this range that are not collected in the fourth quarter of 2024 are expected to be collected in the first quarter of 2025. The Company intends to utilize some of the cash flow from operations expected in the fourth quarter of 2024 to prepay $100 million to $150 million of its outstanding Term Loan B debt by the end of 2024, of which $50 million has already been prepaid subsequent to the third quarter of 2024. Further estimated prepayments of $50 million to $75 million of the Term Loan B debt are anticipated in the first quarter of 2025.
Income tax benefit was $33.9 million and $19.4 million for the three and nine months ended September 30, 2024, respectively, compared to $4.1 million and $52.0 million for the same periods in 2023. See Corporate, Tax and Other Matters below for a discussion of the changes in the effective tax rate.
Diluted loss per common share for the three and nine months ended September 30, 2024 was $1.92 and $1.61, respectively, compared to diluted loss per common share of $0.71 and $2.39, respectively, for the same periods in 2023. The change for both periods in 2024 was primarily due to the factors discussed above that resulted in the change in loss from construction operations for such periods.
Consolidated new awards for the three and nine months ended September 30, 2024 totaled $4.7 billion and $7.1 billion, respectively, compared to $0.8 billion and $5.6 billion for the same periods in 2023. The Civil and Building segments were the primary contributors to the new awards activity in the third quarter of 2024. The most significant new awards and contract adjustments in the third quarter of 2024 included a $1.66 billion mass-transit project in Hawaii; a $1.1 billion water conveyance tunnel project in New York; a healthcare campus project in California valued at more than $1 billion; $138 million of additional funding for certain mass-transit projects in California; and a $113 million military facility project in Guam.
Consolidated backlog as of September 30, 2024 was $14.0 billion, up 38% compared to $10.2 billion as of December 31, 2023, setting a new all-time record that far exceeded the previous record backlog of $11.6 billion reported for the first quarter of 2019. As of September 30, 2024, the mix of backlog by segment was approximately 49% for Civil, 37% for Building and 14% for Specialty Contractors. The Company has submitted or will submit proposals on various large projects and expects owners’ decisions in the fourth quarter of 2024. Accordingly, ending backlog for the fourth quarter of 2024 could reflect further significant growth.
The following table presents the Company’s backlog by business segment, reflecting changes from December 31, 2023 to September 30, 2024:

(in millions) | Backlog at December 31, 2023 | New Awards(a) | Revenue Recognized | Backlog at September 30, 2024(b)
Civil | $ | 4,240.6 |  | $ | 4,218.9 |  | $ | (1,564.5) |  | $ | 6,895.0 |
Building | 4,177.5 |  | 2,226.1 |  | (1,265.6) |  | 5,138.0 |
Specialty Contractors | 1,740.3 |  | 681.1 |  | (429.2) |  | 1,992.2 |
Total | $ | 10,158.4 |  | $ | 7,126.1 |  | $ | (3,259.3) |  | $ | 14,025.2 |

____________________________________________________________________________________________________
(a)New awards consist of the original contract price of projects added to backlog plus or minus subsequent changes to the estimated total contract price of existing contracts.
(b)Backlog may differ from the transaction prices allocated to the remaining performance obligations as disclosed in Note 3 of the Notes to Condensed Consolidated Financial Statements. Such differences relate to the timing of executing a formal contract or receiving a notice to proceed. More specifically, backlog may include awards for which a contract has not yet been executed or a notice to proceed has not yet been issued, but for which there are no remaining major uncertainties that we will proceed with our work on the project (e.g., adequate funding is in place, we have received a notice of intent to award a contract, etc.).
The outlook for the Company’s revenue growth over the next several years remains favorable, especially due to strong new award bookings in the third quarter of 2024, as well as other significant awards that could potentially be booked over the next few months. Many of these newer projects will be executed over a longer timeframe compared to other projects booked in

recent years. However, revenue growth could be hampered by unanticipated project delays or the timing of project bids, awards, commencements, ramp-up activities and completions. We anticipate that we will continue to win our share of significant new project awards resulting from long-term, well-funded capital spending plans by state, local and federal customers, as well as limited competition for many of the larger project opportunities.
Since 2014, voters in 43 states have approved 85 percent of over 3,000 state and local ballot measures, raising an estimated $342 billion in new and renewed revenue funding for transportation investments. The largest of these was in Los Angeles County, where Measure M, a half-cent sales tax increase, was approved in 2016 and is expected to generate $120 billion of funding over 40 years. Funding from this measure is supporting, and is expected to continue to support, several of the Company’s current and prospective projects. More recently, there were more than $50 billion in various state and local transit funding measures on the ballots for elections in November 2024. Despite numerous interest rate increases since March 2022, rates remain at levels that we believe are conducive to continued spending on certain types of projects that have strong end-market demand with adequate available funding, such as mass transit, transportation, bridges, and healthcare, education, and correctional and detention facilities, among others. For the first time in four years, interest rates were lowered in September 2024, and many economists expect further rate reductions over the remainder of 2024 and in 2025, though the actual timing and extent of any future rate reductions remains uncertain. Lower interest rates could support additional demand for continued infrastructure spending. In contrast, should interest rates rise, they could reach levels that may negatively impact demand, especially for certain types of Building segment projects that have already been experiencing such impacts, such as commercial offices and tenant improvement projects, which tend to be more economically sensitive than projects handled by our Civil segment.
The bipartisan Infrastructure Investment and Jobs Act (the “Bipartisan Infrastructure Law” or “BIL”), enacted into law in November 2021, provides for $1.2 trillion of federal infrastructure funding, including $550 billion in new spending for improvements to the country’s surface-transportation network and enhancements to core infrastructure. The law initiated the largest federal investment in public transit ever, the single largest dedicated bridge investment since the construction of the interstate highway system and the largest federal investment in passenger rail since the creation of Amtrak, all in addition to providing for regular annual spending for numerous infrastructure projects. This significant incremental funding is anticipated to be spent over the 10 years from its enactment through 2031, and much of it is allocated for investment in end markets that are directly aligned with the Company’s market focus. Accordingly, the Company believes that this significant level of sustained, incremental funding has benefited, and will continue to favorably impact, the Company’s current work and prospective opportunities over the next decade.
For a more detailed discussion of the operating performance of each business segment, corporate general and administrative expenses and other items, see Results of Segment Operations, Corporate, Tax and Other Matters and Liquidity and Capital Resources below.
Results of Segment Operations
The results of our Civil, Building and Specialty Contractors segments are discussed below.
Civil Segment
Revenue and income (loss) from construction operations for the Civil segment are summarized as follows:

| Three Months Ended September 30, |  | Nine Months Ended September 30,
(in millions) | 2024 | 2023 |  | 2024 | 2023
Revenue | $ | 545.8 |  | $ | 520.5 |  |  | $ | 1,564.5 |  | $ | 1,424.5 |
Income (loss) from construction operations | (12.5) |  | 46.9 |  |  | 133.8 |  | 170.3 |

Revenue for the three months ended September 30, 2024 increased 5% compared to the same period in 2023, primarily due to a net increase in project execution activities driven by certain large mass-transit projects, two airport projects in the Northern Mariana Islands, and the tunneling component of an energy project in British Columbia, partially offset by reduced project execution activities on a mass-transit project in the Midwest that is nearing completion. The increase was also due to the absence of certain prior-year net unfavorable adjustments discussed in the paragraph below. Revenue for the nine months ended September 30, 2024 increased 10% compared to the same period in 2023, primarily due to contributions from the net increased project execution activities mentioned above. The increase for both periods of 2024 was partially offset by an unfavorable adjustment related to an unexpected adverse arbitration decision on a legacy dispute related to a completed bridge project in California, which the Company will appeal.
37

Table of Contents
Loss from construction operations for the three months ended September 30, 2024 was $12.5 million compared to income from construction operations of $46.9 million for the same period in 2023. The decrease was primarily due to a current-quarter unfavorable adjustment of $101.6 million related to an unexpected adverse arbitration decision on a legacy dispute related to the same bridge project in California, which the Company will appeal. The decrease was partially offset by contributions totaling $17.4 million related to the net increase in project execution activities discussed above, an $18.4 million favorable adjustment due to a settlement of a claim associated with a completed highway tunneling project in the Western United States, as well as the absence of prior-year net unfavorable adjustments due to a settlement in 2023 that impacted multiple components of a mass-transit project in California. That settlement resulted in an unfavorable non-cash adjustment in the prior-year period of $23.2 million to one component of the project that was nearing completion, partially offset by a favorable adjustment in the prior-year period of $8.8 million on the other component of the project that had substantial scope of work remaining.
Income from construction operations for the nine months ended September 30, 2024 was $133.8 million compared to $170.3 million for the same period in 2023. The decrease was due to the same factors discussed above for the third quarter of 2024, as well as an unfavorable adjustment of $12.4 million in the second quarter of 2024 that was due to the impact of a settlement on two completed highway projects in the Northeast, mostly offset by a $10.2 million favorable adjustment in the first quarter of 2024 on a mass-transit project in California related to a dispute resolution and associated expected cost savings. The decrease was also due to the absence of prior-year net favorable adjustments totaling $25.6 million on a mass-transit project in California associated with changes in estimates due to improved performance, partially offset by contributions totaling $57.7 million related to the net increase in project execution activities discussed above and the absence of the Civil segment’s portion of prior-year unfavorable adjustments of $13.8 million on a completed transportation project in the Northeast due to the settlement of certain change orders during project closeout.
Operating margin was (2.3)% and 8.6% for the three and nine months ended September 30, 2024, respectively, compared to 9.0% and 12.0% for the same periods in 2023. The changes in operating margin were principally due to the above-mentioned factors that drove the changes in revenue and income (loss) fr om construction operations.
New awards in the Civil segment totaled $3.1 billion and $4.2 billion for the three and nine months ended September 30, 2024, respectively, compared to $469.0 million and $1.5 billion for the same periods in 2023. The most significant new awards and contract adjustments in the third quarter of 2024 included a $1.66 billion mass-transit project in Hawaii; a $1.1 billion water conveyance tunnel project in New York; $138 million of additional funding for certain mass-transit projects in California; and a $113 million military facility project in Guam.
Backlog for the Civil segment was $6.9 billion as of September 30, 2024, up 52% compared to $4.5 billion as of September 30, 2023. The segment continues to experience strong demand reflected in a large, multi-year pipeline of prospective projects, supported by substantial anticipated funding from various voter-approved transportation measures, the BIL, and by public agencies’ long-term spending plans. We believe that the Civil segment is well-positioned to capture its share of these prospective projects.
Building Segment
Revenue and income (loss) from construction operations for the Building segment are summarized as follows:

| Three Months Ended September 30, |  | Nine Months Ended September 30,
(in millions) | 2024 | 2023 |  | 2024 | 2023
Revenue | $ | 435.8 |  | $ | 365.4 |  |  | $ | 1,265.6 |  | $ | 926.4 |
Income (loss) from construction operations | (3.9) |  | 0.1 |  |  | 17.3 |  | (83.9) |

Revenue for the three months ended September 30, 2024 increased 19% compared to the same period in 2023, primarily due to increased project execution activities on various healthcare and educational facility projects in California and a detention facility project in New York. Revenue for the nine months ended September 30, 2024 increased 37% compared to the same period in 2023, primarily due to contributions from the increased project execution activities mentioned above, as well as the absence of a prior-year unfavorable adjustment related to an adverse legal ruling on a completed mixed-use project in New York. The increase for both periods of 2024 was partially offset by an unfavorable adjustment in the third quarter of 2024 related to a settlement on a legacy dispute related to a completed government facility project in Florida.
Loss from construction operations for the three months ended September 30, 2024 was $3.9 million and income from construction operations for the nine months ended September 30, 2024 was $17.3 million, compared to income from construction operations of $0.1 million and loss from construction operations of $83.9 million for the respective periods in 2023. For the third quarter of 2024, the decrease was primarily the result of an unfavorable adjustment of $20.0 million related

to the same settlement on a legacy dispute related to a completed government facility project in Florida, mostly offset by the increased project execution activities discussed above, as well as the absence of the Building segment’s portion of a prior-year unfavorable adjustment of $7.0 million on a completed transportation project in the Northeast due to the settlement of certain change orders during project closeout. For the first nine months of 2024, the significant improvement was principally due to the absence of the aforementioned prior-year unfavorable adjustment related to the adverse legal ruling on a completed mixed-use project in New York that resulted in a non-cash charge of $83.6 million, of which $72.2 million impacted the Building segment, and contributions related to the increased current-year project execution activities discussed above. The improvement was partially offset by the unfavorable impact of the aforementioned settlement on a legacy dispute related to a completed government facility project in Florida.
Operating margin was (0.9)% and 1.4% for the three and nine months ended September 30, 2024, respectively, compared to 0.0% and (9.1)% for the same periods in 2023. The changes in operating margin were principally due to the aforementioned factors that drove the changes in revenue and income (loss) from construction operations.
New awards in the Building segment totaled $1.4 billion and $2.2 billion for the three and nine months ended September 30, 2024, respectively, compared to $249.0 million and $3.0 billion for the same periods in 2023. The nine-month period of 2023 included the award of the Brooklyn Jail project in New York. The most significant new awards and contract adjustments in the third quarter of 2024 included more than $1 billion of additional funding for a healthcare campus project in California. Certain Building segment end markets, such as correctional and detention facilities, healthcare, education, industrial/manufacturing, and hospitality and gaming, continue to show strong demand for new and renovated facilities. However, the proliferation of remote and hybrid work settings at many companies, along with continued higher interest rates, could continue to result in delayed or even canceled Building segment project opportunities, particularly in the corporate office end market.
Backlog for the Building segment was $5.1 billion as of September 30, 2024, the highest backlog for the segment since 2008, and up 18% compared to $4.3 billion as of September 30, 2023. We believe that the Building segment continues to experience strong customer demand as reflected by a large volume of prospective projects across various end markets and geographic locations. In addition, there are various healthcare and education projects underway in California that are in the pre-construction phase, with only a relatively modest amount of our current backlog represented by those projects. Over the next one to two years, these projects are expected to advance into the construction phase, and subsequently we anticipate that we will book significant additional backlog for these projects as a result.
Specialty Contractors Segment
Revenue and loss from construction operations for the Specialty Contractors segment are summarized as follows:

| Three Months Ended September 30, |  | Nine Months Ended September 30,
(in millions) | 2024 | 2023 |  | 2024 | 2023
Revenue | $ | 101.2 |  | $ | 174.8 |  |  | $ | 429.2 |  | $ | 507.9 |
Loss from construction operations | (56.9) |  | (38.4) |  |  | (83.1) |  | (120.7) |

Revenue for the three months ended September 30, 2024 decreased 42% compared to the same period in 2023, primarily due to reduced project execution activities on various electrical and mechanical projects in New York and Florida, all of which are complete or nearing completion. Revenue for the nine months ended September 30, 2024 decreased 15% compared to the same period in 2023, primarily due to the same factors discussed above for the third quarter, as well as reduced project execution activities on an industrial facility project in Arizona. The decrease for the first nine months of 2024 was partially offset by the absence of certain prior-year unfavorable adjustments described in the paragraph below.
Loss from construction operations for the three months ended September 30, 2024 was $56.9 million compared to $38.4 million for the same period in 2023. The higher loss was primarily due to unfavorable adjustments that totaled $43.4 million in the aggregate on several completed projects due to the impact of judgments and settlements, including $17.7 million related to an unfavorable judgment on a completed mass-transit project in California, $11.5 million related to an unfavorable arbitration ruling on a completed mass-transit project in New York, and certain other adjustments that were individually immaterial, as well as the reduced project execution activities discussed above. The higher loss was partially offset by the absence of certain prior-year unfavorable adjustments, including $16.9 million due to changes in estimates on the electrical and mechanical scope of a transportation project in the Northeast and a $9.4 million unfavorable adjustment due to a settlement on a completed mass-transit project in California.
Loss from construction operations for the nine months ended September 30, 2024 was $83.1 million compared to $120.7 million for the same period in 2023. The improvement was primarily due to the absence of certain prior-year
39

Table of Contents
unfavorable adjustments, including $57.0 million due to changes in estimates on the electrical and mechanical scope of the above-mentioned transportation project in the Northeast; a non-cash charge of $25.1 million on an educational facilities project in New York that resulted from an adverse court ruling; an adverse legal ruling on a completed mixed-use project in New York that resulted in a non-cash charge of $83.6 million, of which $11.4 million impacted the Specialty Contractors segment; and the aforementioned $9.4 million unfavorable adjustment on a completed mass-transit project in California. The improvement was partially offset by the unfavorable adjustments impacting the third quarter of 2024, reduced project execution activities for the nine-month period of 2024 discussed above and an unfavorable adjustment of $12.0 million in the first quarter of 2024 due to an arbitration ruling pertaining to a completed electrical project in New York that only provided a partial award to the Company.
Operating margin was (56.2)% and (19.4)% for the three and nine months ended September 30, 2024, respectively, compared to (22.0)% and (23.8)% for the same periods in 2023. The changes in operating margin were principally due to the aforementioned factors that drove the changes in revenue and loss from construction operations.
New awards in the Specialty Contractors segment totaled $227.8 million and $681.1 million for the three and nine months ended September 30, 2024, respectively, compared to $128.5 million and $1.0 billion for the same periods in 2023.
Backlog for the Specialty Contractors segment was $2.0 billion as of September 30, 2024, up 12% compared to $1.8 billion as of September 30, 2023. The Specialty Contractors segment continues to be primarily focused on servicing the Company’s current and prospective large Civil and Building segment projects, particularly in the Northeast and California. We believe that the segment remains well-positioned to capture its share of new projects, leveraging the size and scale of our business units that operate in New York, Texas, Florida and California and the strong reputation held by these business units for high-quality work on large, complex projects.
Corporate, Tax and Other Matters
Corporate General and Administrative Expenses
Corporate general and administrative expenses were $32.5 million and $83.8 million during the three and nine months ended September 30, 2024, respectively, compared to $21.1 million and $56.1 million for the same periods in 2023. The increase in the three and nine months ended September 30, 2024 was primarily due to higher compensation-related expenses, mainly attributable to higher share-based compensation expense. The increase in share-based compensation expense was primarily due to a substantial increase in the Company’s stock price during the 2024 periods, which impacted the fair value of liability-classified awards. These awards are remeasured at fair value at the end of each reporting period with the change recognized in earnings.
Other Income, Net, Interest Expense and Income Tax Benefit

| Three Months Ended September 30, |  | Nine Months Ended September 30,
(in millions) | 2024 | 2023 |  | 2024 | 2023
Other income, net | $ | 4.5 |  | $ | 3.0 |  |  | $ | 15.6 |  | $ | 12.4 |
Interest expense | (21.2) |  | (20.3) |  |  | (63.6) |  | (63.8) |
Income tax benefit | 33.9 |  | 4.1 |  |  | 19.4 |  | 52.0 |

Other income, net for the three and nine months ended September 30, 2024 increased $1.5 million and $3.2 million, respectively, compared to the same periods in 2023.
Interest expense for the three months ended September 30, 2024 increased by $0.9 million compared to the same period in 2023. Interest expense for the nine months ended September 30, 2024 decreased by $0.2 million compared to the same period in 2023. With the anticipated prepayment of a portion of the outstanding Term Loan B in the fourth quarter of 2024 and the first quarter of 2025, as discussed further in Liquidity and Capital Resources, the Company expects interest expense to decrease in 2025 and beyond.
The Company recognized an income tax benefit of $33.9 million and $19.4 million for the three and nine months ended September 30, 2024, respectively. The effective income tax rate was 27.5% and 29.6% for the three and nine months ended September 30, 2024, respectively. The effective income tax rates for both periods were impacted by relatively large tax benefits generated against a forecasted pre-tax loss for the year, which magnified the impact these tax benefits had on the effective income tax rate. In periods with pre-tax losses, tax benefits generated during the period increase the effective income tax rate (and, thus, the income tax benefit to the Company) rather than decreasing the effective rate, as in periods with pre-tax income.

Table of Contents
The effective income tax rate for both the three and nine months ended September 30, 2024 was higher than the 21.0% federal statutory income tax rate primarily due to earnings attributable to noncontrolling interests (for which income taxes are not the responsibility of the Company) and state income taxes (net of the federal tax benefit), partially offset by non-deductible expenses.
The Company recognized an income tax benefit of $4.1 million and $52.0 million for the three and nine months ended September 30, 2023. The effective income tax rate was 13.7% and 36.2% for the three and nine months ended September 30, 2023, respectively. The effective income tax rate for the three months ended September 30, 2023 was lower than the 21.0% federal statutory rate primarily due to the impact of a cumulative catch-up adjustment associated with the change in the Company’s projected 2023 effective tax rate that resulted from the revision of the Company’s forecast. The effective income tax rates for both periods were impacted by relatively large tax benefits generated against a forecasted pre-tax loss for the year, which magnified the impact these tax benefits had on the effective income tax rate. In periods with pre-tax losses, tax benefits generated during the period increase the effective income tax rate (and, thus, the income tax benefit to the Company) rather than decreasing the effective rate, as in periods with pre-tax income. The tax benefits that caused a higher effective tax rate were primarily state income taxes (net of the federal tax benefit), earnings attributable to noncontrolling interests (for which income taxes are not the responsibility of the Company) and a reduction in reserves for unrecognized tax benefits, partially offset by non-deductible expenses.
Liquidity and Capital Resources
Liquidity is provided by available cash and cash equivalents, cash generated from operations, credit facilities and access to capital markets. We have a committed line of credit totaling $170.0 million, which may be used for revolving loans, letters of credit and/or general purposes. We believe that cash generated from operations, along with our unused credit capacity and available cash balances as of September 30, 2024, will be sufficient to fund working capital needs and debt maturities for the next 12 months and beyond, as discussed further below in Debt. We generated significant cash from operations in the first nine months of 2024 as discussed below in Cash and Working Capital. As discussed above in Operating Results, we expect cash generated from operations ranging from $250 million to $400 million in the fourth quarter of 2024 (and, consequently, $425 million to $575 million of cash generated from operations for the full year of 2024), expected to be driven by collections of approximately $180 million related to the resolution of the aforementioned third-quarter 2024 settlements, as well as cash generation related to project execution activities for new and existing projects. The wide range in the estimated generation of operating cash in the fourth quarter of 2024 is due to the uncertainty as to the precise timing of when certain large payments will be collected, though any amounts in this range that are not collected in the fourth quarter of 2024 are expected to be collected in the first quarter of 2025. We intend to utilize some of the cash flow from operations expected in the fourth quarter of 2024 to prepay $100 million to $150 million of our outstanding Term Loan B debt by the end of 2024, of which $50 million has already been prepaid subsequent to the third quarter of 2024. Further estimated prepayments of $50 million to $75 million of the Term Loan B debt are anticipated in the first quarter of 2025. In addition, we expect to benefit from the utilization of available net operating loss carryforwards to reduce our cash outflows for income taxes.
Cash and Working Capital
Cash and cash equivalents were $287.4 million as of September 30, 2024 compared to $380.6 million as of December 31, 2023. Cash immediately available for general corporate purposes was $118.4 million and $145.1 million as of September 30, 2024 and December 31, 2023, respectively, with the remainder being amounts held by our consolidated joint ventures and also our proportionate share of cash held by our unconsolidated joint ventures. Cash held by our joint ventures is available only for joint venture-related uses, including distributions to joint venture partners. In addition, our restricted cash and restricted investments totaled $149.5 million as of September 30, 2024 compared to $144.4 million as of December 31, 2023. Restricted cash and restricted investments at September 30, 2024 were primarily held to secure insurance-related contingent obligations and deposits.
During the nine months ended September 30, 2024, net cash provided by operating activities was $174.0 million. The net cash provided by operating activities for the 2024 period was primarily due to cash generated by earnings sources and a reduction in net project working capital. The reduction in net project working capital was primarily due to an increase in accounts payable, as a result of the timing of payments to subcontractors and vendors, and a decrease in costs and estimated earnings in excess of billings (“CIE”), partially offset by an increase in accounts receivable and a decrease in billings in excess of costs and estimated earnings (“BIE”). As of September 30, 2024, BIE of $1.05 billion exceeded CIE of $966.3 million resulting in a net BIE position for the first time since 2011. During the nine months ended September 30, 2023, net cash provided by operating activities was $180.8 million, which was the second-largest result for the first nine months of any year since the merger between Tutor-Saliba Corporation and Perini Corporation in 2008. The net cash provided by operating activities for the nine-month period of 2023 was primarily due to a decrease in investments in project working capital, partially offset by cash utilized

by earnings sources. The decrease in investments in project working capital was primarily due to a decrease in CIE, an increase in accounts payable due to the timing of payments to suppliers and subcontractors and an increase in BIE.
Cash flow from operating activities for the first nine months of 2024 decreased $6.8 million compared to the same period in 2023. The decrease in cash flow from operating activities for the first nine months of 2024 compared to 2023 primarily reflects a smaller reduction in net project working capital in the current period compared to the prior-year period, mostly offset by cash generated by earning sources in the current period compared to cash used by earnings sources in the same period last year. The smaller reduction in net project working capital in the 2024 period was primarily due to a current-year increase in accounts receivable compared to a decrease last year, a current-year decrease in BIE compared to an increase last year, and a smaller current-year decrease in CIE compared to last year, partially offset by a larger current-year increase in accounts payable compared to last year. Both periods were positively impacted by collections associated with previously disputed matters.
Net cash used in investing activities during the first nine months of 2024 was $27.3 million primarily due to the acquisition of property and equipment for projects (i.e., capital expenditures) totaling $28.3 million and net cash used in investment transactions of $2.0 million, partially offset by proceeds from the sale of property and equipment of $2.9 million. Net cash used in investing activities during the first nine months of 2023 was $43.4 million primarily due to the acquisition of property and equipment for projects totaling $45.6 million, as well as net cash used in investment transactions of $6.9 million, partially offset by proceeds from the sale of property and equipment of $9.0 million.
Net cash used in financing activities was $240.0 million for the first nine months of 2024, which was primarily driven by a $199.3 million net repayment of debt (including the 2024 Senior Notes issuance of $400.0 million and the 2017 Senior Notes redemption of $500.0 million, as well as the $91.0 million principal prepayment on the Term Loan B, all of which are discussed below in Debt), $25.1 million of payments for debt issuance costs related to debt transactions during the period and $12.3 million of net distributions to noncontrolling interests. Net cash used in financing activities was $79.3 million for the first nine months of 2023, which was primarily driven by a $56.0 million net repayment of debt and $22.0 million of net distributions to noncontrolling interests.
At September 30, 2024, we had working capital of $1.2 billion, a ratio of current assets to current liabilities of 1.55 and a ratio of debt to equity of 0.55, compared to working capital of $1.4 billion, a ratio of current assets to current liabilities of 1.66 and a ratio of debt to equity of 0.70 at December 31, 2023.
Debt
2024 Senior Notes Issuance and 2017 Senior Notes Redemption
On April 22, 2024, the Company issued $400.0 million in aggregate principal amount of 11.875% Senior Notes due April 30, 2029 (the “2024 Senior Notes”) in a private placement offering. Interest on the 2024 Senior Notes is payable in arrears semi-annually in April and October of each year, beginning in October 2024.
Prior to April 30, 2026, the Company may redeem the 2024 Senior Notes at a redemption price equal to 100% of the principal amount plus a “make-whole” premium described in the indenture. In addition, prior to April 30, 2026, the Company may redeem up to 40% of the original aggregate principal amount of the 2024 Senior Notes at a redemption price of 111.875% of their principal amount with the “net cash proceeds” received by the Company from one or more equity offerings, as described in the indenture. On or after April 30, 2026, the Company may redeem the 2024 Senior Notes at specified redemption prices described in the indenture. If the Company experiences certain change of control events, holders of the 2024 Senior Notes may require the Company to repurchase all or part of the 2024 Senior Notes at 101% of the principal amount thereof, plus accrued and unpaid interest to the redemption date.
The 2024 Senior Notes are senior unsecured obligations of the Company and are guaranteed by the Company’s existing and future subsidiaries that also guarantee obligations under the Company’s 2020 Credit Agreement. In addition, the indenture for the 2024 Senior Notes provides for customary covenants and includes customary events of default.
The proceeds of the 2024 Senior Notes, together with cash on hand, were used to redeem in full, all of the outstanding obligations in respect of the 2017 Senior Notes. The redemption of the 2017 Senior Notes occurred on May 2, 2024 (the “2017 Senior Notes Redemption”).
2020 Credit Agreement
On August 18, 2020, the Company entered into a credit agreement (as amended, the “2020 Credit Agreement”) with BMO Bank N.A. (f/k/a BMO Harris Bank N.A.), as Administrative Agent, Swing Line Lender and L/C Issuer and other lenders. The 2020 Credit Agreement originally provided for a $425.0 million term loan B facility (the “Term Loan B”) and a $175.0 million
42

Table of Contents
revolving credit facility (the “Revolver”), which was subsequently reduced to $170.0 million following the effectiveness of the 2024 Amendment (as defined and discussed below), with sub-limits for the issuance of letters of credit and swing line loans up to the aggregate amounts of $75.0 million and $10.0 million, respectively. Prior to the 2017 Senior Notes Redemption, if any of the 2017 Senior Notes had remained outstanding beyond certain dates, the maturities of the Term Loan B and the Revolver would have been subject to acceleration (“spring-forward maturity”). However, following the 2017 Senior Notes Redemption and the consummation of the 2024 Amendment, the spring-forward maturity of the Term Loan B is no longer in effect and the spring-forward maturity of the Revolver has been extended (as described below).
On April 15, 2024, the Company entered into an amendment in respect of the 2020 Credit Agreement (the “2024 Amendment”) which, among other changes, (1) extends the existing Revolver maturity date from August 18, 2025 to (a) if any tranche of the Term Loan B, any incremental term loan or any refinancing term loan (or any refinancing or replacement thereof) remains outstanding, the earlier of (i) May 20, 2027 and (ii) the date that is ninety (90) days prior to the final maturity of any tranche of the Term Loan B, any incremental term loan or any refinancing term loan (or any refinancing or replacement thereof), as applicable, and (b) if no obligations are outstanding with respect to any tranche of the Term Loan B, any incremental term loan or any refinancing term loan, August 18, 2027 and (2) permanently reduces the aggregate commitments in respect of the Revolver by $5.0 million from $175.0 million to $170.0 million. The 2024 Amendment became effective on May 2, 2024 upon the completion of the 2017 Senior Notes Redemption.
Subject to certain exceptions, at any time prior to maturity, the 2020 Credit Agreement provides the Company with the right to increase the commitments under the Revolver and/or to establish one or more term loan facilities in an aggregate amount up to (i) the greater of $173.5 million and 50% LTM EBITDA (as defined in the 2020 Credit Agreement) plus (ii) additional amounts if (A) in the case of pari passu first lien secured indebtedness, the First Lien Net Leverage Ratio (as defined in the 2020 Credit Agreement) does not exceed 1.35:1.00, (B) in the case of junior lien secured indebtedness, the Total Net Leverage Ratio, as defined in the 2020 Credit Agreement, does not exceed 3.50:1.00, and (C) in the case of unsecured indebtedness, (x) the Total Net Leverage Ratio does not exceed 3.50:1.00 or (y) the Fixed Charge Coverage Ratio (as defined in the 2020 Credit Agreement) is no less than 2.00:1.00. The balances of indebtedness used in the calculations of the First Lien Net Leverage Ratio and the Total Net Leverage Ratio include offsets for cash and cash equivalents available for general corporate purposes.
As of September 30, 2024, the Revolver had unused available borrowing capacity of $170.0 million, and the outstanding balance of the Term Loan B and the 2024 Senior Notes wer e $272.9 million and $400.0 million, respectively.
The 2020 Credit Agreement requires the Company to make prepayments on the Term Loan B in connection with certain asset sales, receipts of insurance proceeds, incurrences of certain indebtedness and annual excess cash flow (in each case, subject to certain customary exceptions). At December 31, 2023, current maturities of long-term debt in the accompanying Condensed Consolidated Balance Sheets included $91.0 million of principal on the Term Loan B, relating to the mandatory prepayment provision of the 2020 Credit Agreement in respect of annual excess cash flow. The $91.0 million principal prepayment, which was due by the first week of April 2024, was paid in February 2024.
Borrowings under the 2020 Credit Agreement bear interest at variable rates, which have increased since the latter part of 2022 due to changes in market conditions that resulted in increases in the Secured Overnight Financing Rate (“SOFR”) (and the London Interbank Offered Rate (“LIBOR”) prior to the transition to SOFR), in the case of the Term Loan B, and the administrative agent’s prime lending rate, in the case of the Revolver. Effective May 2, 2023, the 2020 Credit Agreement was amended to transition the Company’s original LIBOR option in respect of the Term Loan B to Adjusted Term SOFR. The average borrowing rates on the Term Loan B and the Revolver for the nine months ended September 30, 2024 were approximately 10.2% and 12.0%, respectively. At September 30, 2024, the borrowing rates on the Term Loan B and the Revolver were 9.7% and 11.5%, respectively. For more information regarding the terms of our 2020 Credit Agreement, refer to Note 9 of the Notes to Condensed Consolidated Financial Statements.
The table below presents our actual and required First Lien Net Leverage ratio under the 2020 Credit Agreement for the period, which is calculated on a rolling four-quarter basis:

| Trailing Four Fiscal Quarters Ended
| September 30, 2024
| Actual | Required
First lien net leverage ratio | 0.77 to 1.00 | ≤ 2.25 : 1.00

The 2020 Credit Agreement requires, solely with respect to the Revolver, the Company and its restricted subsidiaries to maintain a maximum First Lien Net Leverage Ratio of 3.50:1.00, effective the fiscal quarter ended December 31, 2022 and increasing to 3.75:1.00 for the fiscal quarter ending March 31, 2023 and subsequently stepping down to 3.00:1.00 for the fiscal

quarter ending June 30, 2023, 2.50:1.00 for the fiscal quarter ending September 30, 2023 and 2.25:1.00 for the fiscal quarter ending December 31, 2023 and each fiscal quarter thereafter. As of September 30, 2024, we were in compliance and expect to continue to be in compliance with the covenants under the 2020 Credit Agreement.
