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 months ended March 31, 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 March 31, 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 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 periods beginning after December 15, 2024, and requires retrospective application to all prior periods presented in the financial statements. The Company is currently evaluating the impact of the guidance on the consolidated financial statements and disclosures.
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. This guidance is effective for fiscal years beginning after December 15, 2024, and requires prospective application with the option to apply it retrospectively. Early adoption is permitted. The Company is currently evaluating the impact of this guidance on the consolidated financial statements and disclosures.

(a)The three-month period ended March 31, 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 determined. Net revenue recognized during the three months ended March 31, 2024 related to performance obligations satisfied (or partially satisfied) in prior periods was immaterial. Revenue was negatively impacted during the three months ended March 31, 2023 related to performance obligations satisfied (or partially satisfied) in prior periods by $108.0 million. 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 March 31, 2024, the aggregate amounts of the transaction prices allocated to the remaining performance obligations of the Company’s construction contracts were $4.1 billion, $1.8 billion and $1.1 billion f or the Civil, Building and Specialty Contractors segments, respectively. As of March 31, 2023, the aggregate amounts of the transaction prices allocated to the remaining performance obligations of the Company’s construction contracts were $4.4 billion, $2.2 billion and $1.2 billion for 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 March 31, 2024 |  | As of December 31, 2023
Retention receivable |  | $ | 550,224 |  |  | $ | 580,926 |
Costs and estimated earnings in excess of billings: |  |  |  |
Claims |  | 519,399 |  |  | 562,646 |
Unapproved change orders |  | 558,521 |  |  | 512,831 |
Other unbilled costs and profits |  | 78,651 |  |  | 68,369 |
Total costs and estimated earnings in excess of billings |  | 1,156,571 |  |  | 1,143,846 |
Capitalized contract costs |  | 103,946 |  |  | 117,913 |

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.
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 xpensed to the associated contract over the period of anticipated use on the project. During the three months ended March 31, 2024, $16.3 million of previously capitalized contract costs were amortized and recognized as expense on the related contracts. During the three months ended March 31, 2023, $10.8 million 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 March 31, 2024 |  | As of December 31, 2023
Retention payable |  | $ | 227,731 |  |  | $ | 223,138 |
Billings in excess of costs and estimated earnings |  | 1,002,268 |  |  | 1,103,530 |
Total contract liabilities |  | $ | 1,229,999 |  |  | $ | 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 months ended March 31, 2024 and 2023 and included in the opening billings in excess of costs and estimated earnings balances for each period totaled $482.0 million and $365.1 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 March 31, 2024 |  | As of December 31, 2023
Cash and cash equivalents available for general corporate purposes |  | $ | 128,942 |  |  | $ | 145,055 |

Restricted cash |  | 14,749 |  |  | 14,116 |
Total cash, cash equivalents and restricted cash |  | $ | 373,053 |  |  | $ | 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.

Anti-dilutive securities not included above |  | 1,421 |  |  | 2,857 |  |  |  |

For the three months ended March 31, 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 period.
(7)Income Taxes
The Company recognized an income tax expense for the three months ended March 31, 2024 of $7.3 million resulting in an effective income tax rate of 21.0%. The effective income tax rate for the three months ended March 31, 2024 was consistent with the 21.0% federal statutory rate as the impacts of rate reductions from earnings attributable to noncontrolling interests (for

which income taxes are not the responsibility of the Company) and federal income tax credits were offset by non-deductible expenses, share-based compensation adjustments and state income taxes (net of federal tax benefit).
The Company recognized an income tax benefit for the three months ended March 31, 2023 of $48.1 million resulting in an effective income tax rate of 49.6%. The effective income tax rate was higher than the 21.0% federal statutory rate primarily due to the pre-tax loss for the period and projected for the year. In periods reporting pre-tax losses, a tax benefit increases the effective income tax rate because it increases the tax benefit generated from the pre-tax loss. The tax benefits that caused a higher effective tax rate were primarily the 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.
(8)Goodwill and Intangible Assets
Goodwill
The following table presents the changes in the carrying amount of goodwill since its inception through March 31, 2024:

Goodwill as of March 31, 2024 |  | $ | 205,143 |  |  | $ | — |  |  | $ | — |  |  | $ | 205,143 |

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 our 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 both the three months ended March 31, 2024 and 2023 was $0.6 million. As of March 31, 2024, future amortization expense related to amortizable intangible assets will be approximately $1.7 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 our 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 months ended March 31, 2024 or 2023.

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 provided for a $425.0 million term loan B facility (the “Term Loan B”) and a $175.0 million (which will be reduced to $170.0 million following the effectiveness of the amendment to the 2020 Credit Agreement entered into on April 15, 2024, as described in further detail in Note 19, Subsequent Events) revolving credit facility (the “Revolver”), 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, except that if any of the 2017 Senior Notes (defined below) remain outstanding beyond future dates specified below, the maturity of certain amounts of the Term Loan B will be accelerated (“spring-forward maturity”). The spring-forward maturity provisions are as follows: (i) if on January 30, 2025, any of the 2017 Senior Notes remain outstanding, the maturity date for one tranche of the Term Loan B (representing 10.2% of the principal balance) shall be January 30, 2025 (which is 91 days prior to the maturity of the 2017 Senior Notes) and (ii) if on April 21, 2025, any of the 2017 Senior Notes remain outstanding, the maturity date for another tranche of the Term Loan B (representing 89.8% of the principal balance) shall be April 21, 2025 (which is 10 days prior to the maturity of the 2017 Senior Notes), subject to certain further exceptions. However, following the redemption of the 2017 Senior Notes, which will occur on May 2, 2024 (as described in further detail in Note 19, Subsequent Events), the spring-forward maturity in respect of both tranches of the Term Loan B will no longer be in effect. The Revolver will mature on August 18, 2025, unless any of the 2017 Senior Notes are outstanding on January 30, 2025, in which case any extensions of credit under the Revolver will mature and the commitments under the Revolver will be reduced to zero, in each case, on January 30, 2025, subject to certain further exceptions. However, following the effectiveness of the April 15, 2024 amendment described in further detail in Note 19, the Revolver will mature (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.
On April 15, 2024, as described in further detail in Note 19, Subsequent Events, the Company entered into an amendment in respect of the 2020 Credit Agreement to, among other things, extend the maturity of the Revolver and permanently reduce the aggregate commitments in respect of the Revolver by $5.0 million from $175.0 million to $170.0 million. The effectiveness of the amendment is subject to the satisfaction or waiver of certain conditions precedent more fully described in Note 19, Subsequent Events.
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.

(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 has 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 is also asserting extra-contractual and statutory claims

UNAUDITED
against the Insurers. STP submitted damages to the Insurers in the King County lawsuit in the amount of $532 million. WSDOT is deemed a plaintiff since WSDOT is an insured under the Policy and had filed its own claim for damages. Hitachi Zosen (“Hitachi”), the manufacturer of the TBM, joined the case as a plaintiff for costs incurred to repair the damages to the TBM.
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 limits recovery of certain damages under the Policy. Based on the rulings of the Court of Appeals, the case will continue 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 also has claims for costs, fees, pre-judgment interest and extra-contractual and statutory claims, which are not subject to the Policy limits. The case has been scheduled for trial commencing September 23, 2024.
In addition, STP has a pending case in the Washington Superior Court against HNTB Corporation (“HNTB”), its 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. STP’s complaint seeks in excess of $640 million. The case is scheduled for trial to commence on April 27, 2025.
With respect to STP’s direct and indirect claims against the Insurers and 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.
(12)Share-Based Compensation
As of March 31, 2024, there were 1,457,658 share s of common stock available for grant under the Tutor Perini Corporation Omnibus Incentive Plan. During the three months ended March 31, 2024 and 2023, the Company granted the following share-based instruments: (1) RSUs totaling 30,000 and 590,188, respectively, with weighted-average grant date fair values per unit of $12.68 and $8.66, respectively; (2) cash-settled performance stock units (“CPSUs”) totaling 645,180 and 901,541, respectively, with weighted-average grant date fair values per unit of $19.17 and $13.78, respectively; and (3) deferred cash awards (“DCAs”), including cash-settled stock units, with service-based vesting conditions and payouts indexed to shares of the Company’s common stock totaling 673,855 and 90,000, respectively, with weighted-average grant date fair values per unit of $12.75 and $8.98, respectively.
As of March 31, 2024 and December 31, 2023, the Company recognized liabilities for CPSUs, RSUs with guaranteed minimum payouts and DCAs on the Condensed Consolidated Balance Sheets totaling approximately $7.5 million and $4.9 million, respectively. During the three months ended March 31, 2024, the Company paid approximately $1.0 million, respectively, to settle certain awards.
For the three months ended March 31, 2024 and 2023, the Company recognized, as part of general and administrative expenses, costs for share-based payment arrangements totaling $5.5 million and $3.1 million, respectively. As of March 31, 2024, the balance of unamortized share-based compensation expense was $37.5 million, which is expected to be recognized over a weighted-average period of 2.4 years.

(13)Employee Pension Plans
The Company has a defined benefit pension plan and an unfunded supplemental retirement plan. Effective June 1, 2004, all benefit accruals under these plans were frozen; however, the current vested benefit was preserved. The pension disclosure presented below includes aggregated amounts for both of the Company’s plans.
The following table sets forth a summary of the net periodic benefit cost for the three months ended March 31, 2024 and 2023:

| Three Months Ended March 31, |  |

Recognized net actuarial losses | 437 |  | 413 |  |  |  |
Net periodic benefit cost | $ | 635 |  | $ | 659 |  |  |  |

The Company contributed $0.7 million to its defined benefit pension plan during the three months ended March 31, 2024. The Company expects to contribute an additional $1.8 million in cash by the end of 2024. Due to availability of our prefunded pension balance related to the defined benefit pension plan, the Company was not required to make any cash payments during the three months ended March 31, 2023.
(14)Fair Value Measurements
The fair value hierarchy established by ASC 820, Fair Value Measurement, prioritizes the use of inputs used in valuation techniques into the following three levels:
•Level 1 inputs are observable quoted prices in active markets for identical assets or liabilities
•Level 2 inputs are observable, either directly or indirectly, but are not Level 1 inputs
•Level 3 inputs are unobservable
The following fair value hierarchy table presents the Company’s assets that are measured at fair value on a recurring basis as of March 31, 2024 and December 31, 2023:

Total investments in lieu of retention | 11,398 |  | (55) |  |  | 49,726 |  | (1,895) |  |  | 61,124 |  | (1,950) |

The unrealized losses in AFS debt securities as of March 31, 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 March 31, 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 three months ended March 31, 2024.

The amortized cost and fair value of AFS debt securities by contractual maturity as of March 31, 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 | $ | 38,792 |  | $ | 38,009 |
Due after one year through five years | 174,478 |  | 171,095 |
Due after five years | 10,030 |  | 9,009 |
Total | $ | 223,300 |  | $ | 218,113 |

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 2017 Senior Notes was $495.4 million and $490.9 million as of March 31, 2024 and December 31, 2023, respectively. The fair values of the 2017 Senior Notes were determined using Level 1 inputs, specifically current observable market prices. The fair value of the Term Loan B was $274.4 million and $358.9 million as of March 31, 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 March 31, 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 March 31, 2024, 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. 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 March 31, 2024.
As of March 31, 2024, the Company’s Condensed Consolidated Balance Sheets included current and noncurrent assets of $473.2 million and $33.8 million, respectively, as well as current liabilities of $481.2 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.

____________________________________________________________________________________________________
(a)During the three months ended March 31, 2024, the Company’s income (loss) from construction operations was impacted by an unfavorable adjustment of $12.0 million ($8.8 million, or $0.17 per diluted share, after tax) 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, as well as by a favorable adjustment of $10.2 million ($7.5 million, or $0.14 per diluted share, after tax) on a Civil segment mass-transit project in California related to a dispute resolution and associated expected cost savings.
(b)Consists primarily of corporate general and administrative expenses.
(c)Depreciation and amortization is included in income (loss) from construction operations.
(d)During the three months ended March 31, 2023, the Company’s income (loss) from construction operations was unfavorably 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, or $1.17 per diluted share, after-tax), of which $72.2 million impacted the Building segment and $11.4 million impacted the Specialty Contractors segment, as well as an unfavorable adjustment of $28.0 million ($22.2 million, or $0.43 per diluted share, after tax) for a Civil segment mass-transit project in California, resulting from the successful negotiation of significant lower margin (and lower risk) change orders which increased the project’s overall estimated profit but reduced the project’s percentage of completion and overall margin percentage as of March 31, 2023.

(19)Subsequent Events
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 notes at a redemption price of 111.875% of their principal amount with the proceeds received by the Company from any offering of the Company’s equity. On or after April 30, 2026, the Company may redeem the 2024 Senior Notes at specified redemption prices described in the indenture. Upon a change of control, 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 cov enants on restricting certain payments and includes customary events of default.
The proceeds of the 2024 Senior Notes, together with cash on hand, will be used to redeem in full, all of the outstanding obligations in respect of the 2017 Senior Notes, resulting in a total net reduction to the Company’s outstanding principal debt balance of $100.0 million. A Notice of Conditional Full Redemption was delivered to holders of the 2017 Senior Notes on April 17, 2024, and the redemption of the 2017 Senior Notes will occur on May 2, 2024.

Executive Overview
Operating Results
Consolidated revenue for the three months ended March 31, 2024 was $1.05 billion compared to $776.3 million for the same period in 2023. The change was primarily driven by increased project execution activities on a Civil segment mass-transit project in California, a Building segment detention facility project in New York and a Building segment mass-transit project in California, as well as by the absence of certain prior-year unfavorable adjustments, as discussed in more detail below in Results of Segment Operations.
Income from construction operations for the three months ended March 31, 2024 was $48.8 million, an improvement of $130.7 million compared to loss from construction operations of $81.9 million for the same period in 2023. The significant improvement was principally due to the absence of certain prior-year unfavorable adjustments, as discussed further below in Results of Segment Operations, as well as contributions related to the increased project execution activities discussed above. The improvement was also due to a favorable adjustment in the first quarter of 2024 of $10.2 million on a Civil segment mass-transit project in California related to a dispute resolution and associated expected cost savings. The results for the first quarter of 2024 were negatively impacted by an unfavorable adjustment of $12.0 million 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.
The effective tax rate was 21.0% for the three months ended March 31, 2024 compared to 49.6% for the comparable period in 2023. See Corporate, Tax and Other Matters below for a discussion of the change in the effective tax rate.
Diluted earnings per common share for the three months ended March 31, 2024 was $0.30, compared to diluted loss per common share of $0.95 for the same period in 2023. The improvement for the first quarter of 2024, as compared to the same quarter last year, was primarily due to the factors discussed above that resulted in the change in income (loss) from construction operations.
Consolidated new awards for the three months ended March 31, 2024 totaled $872.8 million compared to $766.7 million for the same period in 2023. The Building and Civil segments were the primary contributors to the new award activity in the first quarter of 2024. The most significant new awards and contract adjustments in the first quarter of 2024 included a $243 million health care facility project in California; a $73 million airport hangar project in Florida; $66 million of additional funding for several other health care projects in California; $55 million for three U.S. Navy projects in Diego Garcia; and $52 million of additional funding for three mass-transit projects in California.
Consolidated backlog as of March 31, 2024 was $10.0 billion, down slightly compared to $10.2 billion as of December 31, 2023. As of March 31, 2024, the mix of backlog by segment was approximately 41% for Civil, 42% for Building and 17% for Specialty Contractors.
The following table presents the Company’s backlog by business segment, reflecting changes from December 31, 2023 to March 31, 2024:

(in millions) | Backlog at December 31, 2023 | New Awards(a) | Revenue Recognized | Backlog at March 31, 2024(b)
Civil | $ | 4,240.6 |  | $ | 328.2 |  | $ | (472.2) |  | $ | 4,096.6 |
Building | 4,177.5 |  | 404.3 |  | (411.9) |  | 4,169.9 |
Specialty Contractors | 1,740.3 |  | 140.3 |  | (164.9) |  | 1,715.7 |
Total | $ | 10,158.4 |  | $ | 872.8 |  | $ | (1,049.0) |  | $ | 9,982.2 |

____________________________________________________________________________________________________
(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.

Table of Contents
(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 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. 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 some of the largest project opportunities.
In elections over the past decade, voters have approved thousands of 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. Despite numerous interest rate increases since March 2022, rates are still 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 health care, educational, and correctional and detention facilities, among others. Many economists believe that interest rates will begin falling sometime during 2024, although the timing and extent of any reductions remains uncertain as a result of continued inflation volatility. Lower interest rates would likely support additional demand for continued infrastructure spending. In contrast, should interest rates rise further, they could reach levels that may negatively impact demand, especially for certain types of Building segment projects, 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 Law was enacted into law in November 2021, and 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 next 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 from construction operations for the Civil segment are summarized as follows:

| Three Months Ended March 31, |  |
(in millions) | 2024 | 2023 |  |  |
Revenue | $ | 472.2 |  | $ | 349.9 |  |  |  |
Income from construction operations | 70.7 |  | 18.0 |  |  |  |

Revenue for the three months ended March 31, 2024 increased 35% compared to the same period in 2023. The growth was largely due to increased project execution activities on a mass-transit project in California and the tunneling component of an energy project in British Columbia. The change was also favorably impacted by the absence of a prior-year unfavorable adjustment, as further discussed in the paragraph below.
32

Table of Contents
Income from construction operations for the three months ended March 31, 2024 was $70.7 million, up 293% compared to $18.0 million for the same period in 2023. The increase was primarily due to the absence of a prior-year temporary unfavorable impact of $28.0 million from the successful negotiation of significant lower margin (and lower risk) change orders on a mass-transit project in California, as well as contributions related to the increased project execution activities discussed above. The increase was also due to 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.
Operating margin was 15.0% for the three months ended March 31, 2024 compared to 5.1% for the same period in 2023. The increase in operating margin was principally due to the above-mentioned factors that drove the changes in revenue and income from construction operations.
New awards in the Civil segment totaled $328.2 million for the three months ended March 31, 2024 compared to $379.1 million for the same period in 2023. The most significant new awards and contract adjustments in the first quarter of 2024 included $55 million for three U.S. Navy projects in Diego Garcia and $52 million of additional funding for three mass-transit projects in California.
Backlog for the Civil segment was $4.1 billion as of March 31, 2024 compared to $4.4 billion as of March 31, 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 and the BIL, and by public agencies’ long-term spending plans. The Civil segment is well-positioned to capture its share of these prospective projects.
Building Segment
Revenue and income (loss) f rom construction operations for the Building segment are summarized as follows:

| Three Months Ended March 31, |  |
(in millions) | 2024 | 2023 |  |  |
Revenue | $ | 411.9 |  | $ | 229.6 |  |  |  |
Income (loss) from construction operations | 16.1 |  | (70.2) |  |  |  |

Revenue for the three months ended March 31, 2024 increased 79% compared to the same period in 2023 primarily due to increased project execution activities on a detention facility project in New York, a mass-transit project in California and a health care facility project in California, 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.
Income from construction operations for the three months ended March 31, 2024 was $16.1 million compared to loss from construction operations of $70.2 million for the same period in 2023. The significant improvement was principally due to the absence of the aforementioned 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. The improvement was also driven by contributions related to increased project execution activities in revenue discussed above, as well as an immaterial favorable adjustment in the 2024 period resulting from a legal ruling related to a completed hospitality and gaming project.
Operating margin was 3.9% for the three months ended March 31, 2024 compared to (30.6)% for the same period in 2023. The change in operating margin was 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 $404.3 million for the three months ended March 31, 2024 compared to $233.5 million for the same period in 2023. The most significant new awards and contract adjustments in the first quarter of 2024 included a $243 million health care facility project in California; a $73 million airport hangar project in Florida; and $66 million of additional funding for several other health care projects in California. The lingering effects of COVID-19, including the proliferation of remote and hybrid work for many businesses, as well as slowed economic conditions caused by inflation and higher interest rates, could continue to result in certain delayed or even canceled Building segment project opportunities, particularly in the corporate office end market. However, other Building segment end markets, such as correctional and detention facilities, health care, education, industrial/manufacturing, and hospitality and gaming, continue to show strong demand for new and renovated facilities.
33

Table of Contents
Backlog for the Building segment was $4.2 billion as of March 31, 2024, up 87% compared to $2.2 billion as of March 31, 2023. 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.
Specialty Contractors Segment
Revenue and loss from construction operations for the Specialty Contractors segment are summarized as follows:

| Three Months Ended March 31, |  |
(in millions) | 2024 | 2023 |  |  |
Revenue | $ | 164.9 |  | $ | 196.8 |  |  |  |
Loss from construction operations | (18.3) |  | (12.4) |  |  |  |

Revenue for the three months ended March 31, 2024 decreased 16% compared to the same period in 2023. The decrease was principally due to reduced project execution activities on an industrial facility project in Arizona and the electrical and mechanical components of a completed transportation project in the Northeast. The decrease was also the result of an unfavorable adjustment in the first quarter of 2024 due to an arbitration ruling that only provided a partial award to the Company pertaining to a completed electrical project in New York. The revenue decline was partially offset by the absence of a prior-year unfavorable adjustment related to the adverse legal ruling on a completed mixed-use project in New York.
Loss from construction operations for the three months ended March 31, 2024 was $18.3 million compared to $12.4 million for the same period in 2023. The change was primarily the result of an unfavorable adjustment in the first quarter of 2024 of $12.0 million due to the above-mentioned arbitration ruling on a completed electrical project in New York, as well as an immaterial unfavorable adjustment due to a settlement on a completed mass-transit project in California. The impact of these unfavorable adjustments was largely offset by the absence of a 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 $11.4 million impacted the Specialty Contractors segment.
Operating margin was (11.1)% for the three months ended March 31, 2024 compared to (6.3)% for the same period in 2023. The change in operating margin was 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 $140.3 million for the three months ended March 31, 2024, slightly down compared to $154.1 million for the same period in 2023.
Backlog for the Specialty Contractors segment was $1.7 billion as of March 31, 2024, up 37.6% compared to $1.2 billion as of March 31, 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. 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 $19.7 million and $16.4 million during the three months ended March 31, 2024 and 2023, respectively. The increase in the three months ended March 31, 2024 was primarily due to higher compensation-related expenses, mainly attributable to higher share-based compensation expense on liability-classified awards resulting from the impact of the increase in the Company’s stock price during the 2024 period.
Other Income, Net, Interest Expense and Income Tax (Expense) Benefit

| Three Months Ended March 31, |  |
(in millions) | 2024 | 2023 |  |  |
Other income, net | $ | 5.3 |  | $ | 6.4 |  |  |  |
Interest expense | (19.3) |  | (21.5) |  |  |  |
Income tax (expense) benefit | (7.3) |  | 48.1 |  |  |  |

34

Table of Contents
Other income, net for the three months ended March 31, 2024 decreased by $1.1 million compared to the same period in 2023.
Interest expense for the three months ended March 31, 2024 decreased by $2.2 million compared to the same period in 2023. The decrease in the 2024 period was substantially due to absence of Revolver borrowings, as well as a lower balance of outstanding Term Loan B borrowings, primarily resulting from the $91.0 million prepayment of Term Loan B principal in February 2024, as discussed below in Liquidity and Capital Resources.
The Company recognized an income tax expense for the three months ended March 31, 2024 of $7.3 million resulting in an effective income tax rate of 21.0%. The effective income tax rate for the three months ended March 31, 2024 was consistent with the 21.0% federal statutory rate as the impacts of rate reductions from earnings attributable to noncontrolling interests (for which income taxes are not the responsibility of the Company) and federal income tax credits were offset by non-deductible expenses, share-based compensation adjustments and state income taxes (net of federal tax benefit).
The effective income tax rate was 49.6% for the three months ended March 31, 2023. The effective income tax rate for the 2023 period was higher than the 21.0% federal statutory rate primarily due to the pre-tax loss for the period and projected for the year. In periods reporting pre-tax losses, a tax benefit increases the effective income tax rate because it increases the tax benefit generated from the pre-tax loss. The tax benefits that caused a higher effective tax rate were primarily the 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.
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 $175.0 million (to be reduced to $170.0 million as discussed further in Debt and in Note 19 of the Notes to Condensed Consolidated Financial Statements), 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 March 31, 2024, will be sufficient to fund working capital needs and debt maturities for the next 12 months and beyond, as discussed further in Debt below. We generated significant operating cash flow in the first quarter of 2024 as discussed below in Cash and Working Capital. We expect strong operating cash flow to continue for the remainder of 2024, based on projected cash collections, both from project execution activities and the resolution of additional outstanding claims and unapproved change orders, including COVID-19-related cost recoveries from certain customers. 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 $358.3 million as of March 31, 2024 compared to $380.6 million as of December 31, 2023. Cash immediately available for general corporate purposes was $128.9 million and $145.1 million as of March 31, 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 $145.2 million as of March 31, 2024 compared to $144.4 million as of December 31, 2023. Restricted cash and restricted investments at March 31, 2024 were primarily held to secure insurance-related contingent obligations and deposits.
During the three months ended March 31, 2024, net cash provided by operating activities was $98.3 million, the second-largest result for the first three 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 2024 period was primarily due to cash generated by earnings sources and a decrease in investment in project working capital. The decrease in investment in project working capital was primarily due to an increase in accounts payable, as a result of the timing of payments to subcontractors and vendors, partially offset by a decrease in billings in excess of costs and estimated earnings (“BIE”). During the three months ended March 31, 2023, net cash provided by operating activities was $21.3 million. The net cash provided by operating activities for the 2023 period 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 costs and estimated earnings in excess of billings (“CIE”) and decreases in accounts receivable and retention receivable that resulted from improved collection activity.
Cash flow from operating activities increased $76.9 million when comparing the first three months of 2024 with the same period in 2023. The increase in cash flow from operating activities for the first three months of 2024 compared to 2023 primarily reflects cash generated by earning sources in the current period compared to cash used by earnings sources in the same period last year, partially offset by a smaller decrease in investment in working capital in the current period compared to the prior-year period. The smaller decrease in investment in working capital in the 2024 period was primarily due to a current-

year decrease in BIE compared to an increase last year, a current-year increase in CIE compared to a decrease last year and a current-year increase in accounts receivable compared to a decrease last year, partially offset by a current-year increase in accounts payable compared to a decrease last year. Both periods were positively impacted by collections associated with previously disputed matters.
Net cash used in investing activities during the first three months of 2024 was $10.3 million primarily due to the acquisition of property and equipment for projects (i.e., capital expenditures) totaling $10.4 million. Net cash used in investing activities during the first three months of 2023 was $6.9 million primarily due to the acquisition of property and equipment for projects totaling $17.8 million, partially offset by proceeds from the sale of property and equipment of $6.5 million and net proceeds from investment transactions of $4.4 million.
Net cash used in financing activities was $109.6 million for the first three months of 2024, which was primarily driven by $100.2 million of repayments of debt (including the $91.0 million principal repayment on the Term Loan B as discussed below in Debt) and $7.4 million of distributions to noncontrolling interests. Net cash provided by financing activities was $14.4 million for the first three months of 2023, which was primarily driven by $21.4 million of net proceeds from borrowings, partially offset by $6.5 million of net distributions to noncontrolling interests.
At March 31, 2024, we had working capital of $1.4 billion, a ratio of current assets to current liabilities of 1.70 and a ratio of debt to equity of 0.61, 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
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 provides for a $425.0 million term loan B facility (the “Term Loan B”) and a $175.0 million revolving credit facility (the “Revolver”), which will be reduced to $170.0 million following the effectiveness of the amendment to the 2020 Credit Agreement entered into on April 15, 2024, as described further detail below and in Note 19 of the Notes to Condensed Consolidated Financial Statements, 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.
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.
The Term Loan B will mature on August 18, 2027, except that if any of the 2017 Senior Notes (defined below) remain outstanding beyond future dates specified below, the maturity of certain amounts of the Term Loan B will be accelerated (“spring-forward maturity”). The spring-forward maturity provisions are as follows: (i) if, on January 30, 2025, any of the 2017 Senior Notes remain outstanding, the maturity date for one tranche of the Term Loan B (representing 10.2% of the principal balance) shall be January 30, 2025 (which is 91 days prior to the maturity of the 2017 Senior Notes) and (ii) if on April 21, 2025, any of the 2017 Senior Notes remain outstanding, the maturity date for another tranche of the Term Loan B (representing 89.8% of the principal balance) shall be April 21, 2025 (which is 10 days prior to the maturity of the 2017 Senior Notes), subject to certain further exceptions. However, following the redemption of the 2017 Senior Notes, which will occur on May 2, 2024 (as described in further detail below), the spring-forward maturity in respect of both tranches of the Term Loan B will no longer be in effect.

The Revolver will mature on August 18, 2025, unless any of the 2017 Senior Notes are outstanding on January 30, 2025, in which case any extensions of credit under the Revolver will mature and the commitments available under the Revolver will be reduced to zero, in each case, on January 30, 2025, subject to certain further exceptions. However, following the effectiveness of the April 15, 2024 amendment discussed below, the Revolver will mature (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.
On April 15, 2024, as described in further detail in Note 19 of the Notes to the Condensed Consolidated Financial Statements, the Company entered into an amendment in respect of the 2020 Credit Agreement to, among other things, extend the maturity of the Revolver (as described above) and permanently reduce the aggregate commitments in respect of the Revolver by $5.0 million from $175.0 million to $170.0 million. The effectiveness of the amendment is subject to the satisfaction or waiver of certain conditions precedent more fully described in Note 19 of the Notes to Condensed Consolidated Financial Statements.
As of March 31, 2024, the Revolver had unused available borrowing capacity of $175.0 million, and the outstanding balance of the Term Loan B and the 2017 Senior Notes were $275.1 million and $500.0 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 for the three months ended March 31, 2024 was approximately 9.2%. There were no borrowings under the Revolver during the three months ended March 31, 2024. At March 31, 2024, the borrowing rates on the Term Loan B and the Revolver were 10.2% and 12.3%, 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
| March 31, 2024
| Actual | Required
First lien net leverage ratio | 1.12 to 1.00 | ≤ 2.25 : 1.00

On October 31, 2022, the 2020 Credit Agreement was amended to increase the maximum First Lien Net Leverage Ratio covenant level for certain fiscal quarters. On March 10, 2023, the 2020 Credit Agreement was further amended to set the maximum First Lien Net Leverage Ratio covenant level to 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 March 31, 2024, we were in compliance and expect to continue to be in compliance with the covenants under the 2020 Credit Agreement.
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 notes at a redemption price of 111.875% of their principal amount with the proceeds received by the Company from any offering of the Company’s equity. On or after April 30, 2026, the Company may redeem the 2024 Senior Notes at specified redemption prices described in the indenture. Upon a change of control, 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 on certain payments and includes customary events of default.
The proceeds of the 2024 Senior Notes, together with cash on hand, will be used to redeem in full, all of the outstanding obligations in respect of the 2017 Senior Notes, resulting in a total net reduction to the Company’s outstanding principal debt balance of $100.0 million. A Notice of Conditional Full Redemption was delivered to holders of the 2017 Senior Notes on April 17, 2024, and the redemption of the 2017 Senior Notes will occur on May 2, 2024.
