Comparison of 2023 to 2022 Results

For a discussion comparing our 2023 results to our 2022 results, refer to Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations in our Form 10-K for the year ended December 31, 2023, as filed with the SEC on February 28, 2024.

Executive Overview

Operating Results

Consolidated revenue for 2024 was $4.3 billion, up 12% compared to $3.9 billion for 2023. The increase was primarily driven by significant growth in the Building and Civil segments, as the Company has been successful in pursuing and winning new work and has experienced increased project execution activities on several of the newer projects. The increase was partially offset by reduced project execution activities in the Specialty Contractors segment due to several projects that have completed or are nearing completion. The increase in 2024 was also due to the absence of certain prior-year net unfavorable adjustments, as discussed in more detail below and in Results of Segment Operations. The 2024 period was also adversely impacted by certain current-year net unfavorable adjustments, also discussed in more detail below and in Results of Segment Operations.

Loss from construction operations for 2024 was $103.8 million compared to $114.6 million for 2023. The reduced loss from construction operations in 2024 was primarily due to contributions related to an overall net increase in project execution activities that totaled $93.2 million. The improvement was also driven by 1) various changes in estimates for project charges, net of positive impacts from improved productivity and efficiencies on certain projects, which had an aggregate net unfavorable impact of $36.4 million in 2024 compared to $117.2 million in 2023, partially offset by 2) certain legal judgments or decisions that had net unfavorable impacts totaling $167.7 million in 2024 compared to $122.2 million in 2023; 3) various settlements that had a net unfavorable impact of $45.8 million in 2024 compared to a net favorable impact of $8.4 million in 2023; and 4) temporary aggregate negative project adjustments of $97.2 million in 2024 compared to $79.2 million in 2023 due to both the successful negotiation of significant lower margin (and lower risk) change orders and increases in unapproved work on various projects, the temporary impacts to earnings of which are expected to reverse themselves over the remaining lives of the projects.

Legal judgments or decisions during 2024 resulted in net unfavorable impacts of $167.7 million, including $101.6 million pertaining to an unexpected adverse arbitration decision on a legacy dispute related to a completed Civil segment bridge project in California, which the Company is appealing; $17.7 million due to an unfavorable judgment on a completed Specialty Contractors segment mass-transit project in California; and $17.4 million due to an unfavorable legal ruling on a completed Civil segment highway project in Virginia.

Legal judgments or decisions during 2023 resulted in net unfavorable impacts of $122.2 million, including an adverse legal ruling on a completed mixed-use project in New York, which resulted in a non-cash charge of $83.6 million, of which $72.2 million impacted the Building segment and $11.4 million impacted the Specialty Contractors segment, and a $24.7 million non-cash charge that resulted from an adverse court ruling on a Specialty Contractors segment educational facilities project in New York.

Settlements during 2024 had a net unfavorable impact of $45.8 million, which included an unfavorable adjustment of $20.0 million associated with the settlement of a legacy dispute related to a completed Building segment government facility project in Florida and the net unfavorable impact of various other settlements that were individually immaterial. The impact of these unfavorable adjustments was partially offset by a favorable adjustment of $18.4 million due to a settlement of a claim associated with a completed Civil segment highway tunneling project in the western United States.

Settlements during 2023 had a net favorable impact of $8.4 million, which included favorable adjustments totaling $58.1 million resulting from the settlement of change orders and changes in estimates due to improved performance on a Civil segment project on the West Coast. This favorable impact was mostly offset by the net unfavorable impacts from other settlements including the net unfavorable impact of $14.4 million from a settlement that affected multiple components of a Civil segment mass-transit project in California. This settlement 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 to one component of the project that is nearing completion, partially offset by a favorable adjustment of $8.8 million on the other component of the project that has substantial scope of work remaining. The net unfavorable impact in 2023 from these two adjustments is expected to be mitigated by the increased profit generated from future work on the project. Other settlements in 2023 included a $13.1 million unfavorable non-cash impact (split evenly between the Civil and Building segments) related to a completed transportation project in the Northeast and the net unfavorable impact of various other settlements that were individually immaterial.

Temporary aggregate negative project adjustments referred to above for 2024 of $97.2 million included a temporary non-cash impact of $31.8 million in the fourth quarter for a Civil segment project on the West Coast, which primarily resulted from significant changes that have been negotiated, or are being negotiated, that carry lower margin (and lower risk) that reduced the project’s percentage of completion and overall margin percentage. The remaining amount of temporary negative project adjustments reflected individually immaterial non-cash adjustments due to the successful negotiation of significant lower margin (and lower risk) change orders and growth of unapproved change orders. The temporary impact to earnings resulting from these adjustments is expected to reverse itself over the remaining life of the project.

Temporary aggregate negative project adjustments referred to above for 2023 of $79.2 million included a temporary unfavorable non-cash impact of $40.7 million resulting from the successful negotiation of significant lower margin (and lower risk) change orders on a Civil segment project on the West Coast. These approved change orders increased the project’s overall estimated profit but reduced the project’s percentage of completion and overall margin percentage. This temporary reduction to earnings is expected to reverse itself over the remaining life of the project. The remaining amount of temporary negative project adjustments were individually immaterial and were due to growth in unapproved change orders on various projects that reduced the projects’ percentage of completion and profit margin, which are also expected to reverse over the remaining lives of the projects.

Table of Contents

Other significant project charges during 2024 had a net unfavorable impact of $36.4 million, as discussed above, which consisted of the negative impact from changes in estimates on various projects, mostly offset by positive impacts from improved productivity and efficiencies on certain projects. Other significant project charges during 2024 included unfavorable adjustments of $25.9 million on a Building segment government building project in Florida that is now nearing completion, primarily due to increased costs associated with external subcontractors and resolution of certain delay change orders, $15.1 million due to changes in estimates on an otherwise profitable Civil segment mass-transit project in California that is nearly complete, and the net favorable impact of changes in estimates on various other projects that were individually immaterial. All of these project charges and changes in estimates were due to changes in facts and circumstances that were identified in 2024.

Other significant project charges during 2023 had a net unfavorable impact of $117.2 million, and included $62.2 million of unfavorable non-cash adjustments due to changes in estimates on the electrical and mechanical scope of a completed transportation project in the Northeast associated with changes in the expected recovery on certain unapproved change orders resulting from ongoing negotiations; an unfavorable adjustment of $16.9 million on a Specialty Contractors segment multi-unit residential project in New York due to changes in estimates resulting from incremental costs to complete the project and ongoing negotiations on unapproved change orders; a $14.9 million unfavorable adjustment due to changes in estimates due to recent negotiations and incremental cost incurred during project closeout (split evenly between the Civil and Building segments) on the same completed transportation project in the Northeast discussed above; a $14.6 million unfavorable adjustment on a Building segment government building project in Florida primarily due to increased costs associated with an external subcontractor; and the net unfavorable impact of changes in estimates on various other projects that were individually immaterial. All of these project charges and changes in estimates were due to changes in facts and circumstances that were identified in 2023.

Furthermore, loss from construction operations for the year ended December 31, 2024 was negatively impacted by share-based compensation expense of $40.4 million compared to share-based compensation expense of $12.3 million in 2023. The increase in share-based compensation expense in 2024 was primarily due to a substantial increase in the Company’s stock price throughout the year, which impacted the fair value of liability-classified awards. These liability-classified awards are remeasured at fair value at the end of each reporting period with the change recognized in earnings. These types of awards were issued in past years as a short-term solution to deal with a depleted share pool under the Tutor Perini Corporation Omnibus Incentive Plan and a low stock price.

The effective income tax rate for 2024 was 29.3% compared to 30.1% for 2023. See Corporate, Tax and Other Matters below for a discussion of the change in the effective tax rate.

Diluted loss per common share for 2024 was $3.13 compared to $3.30 for 2023. The change in 2024 was primarily due to the factors discussed above that led to the change in loss from construction operations.

The Company generated record cash flow from operations of $503.5 million in 2024 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. The Company utilized some of its cash flow from operations for repayments of its outstanding Term Loan B debt, which was paid down by $245.3 million in 2024. During the first quarter of 2025, the Company voluntarily repaid the remaining $121.9 million outstanding balance of the Term Loan B.

Consolidated new awards in 2024 were $12.8 billion compared to $6.1 billion in 2023. The Civil and Building segments were the primary contributors to the new award activity in 2024. Significant new awards and contract adjustments in 2024 included the $3.76 billion Manhattan Jail project in New York; the $1.66 billion City Center Guideway and Stations project in Hawaii; a $1.4 billion healthcare campus project in California; the $1.13 billion Newark AirTrain Replacement project in New Jersey; the $1.1 billion Kensico-Eastview Connection Tunnel project in New York; $479 million of additional funding for certain mass-transit projects in California; $449 million for two healthcare facility projects in California; $331 million for the Apra Harbor Waterfront Repairs project in Guam; a $229 million airport terminal connectors project at Fort Lauderdale-Hollywood International Airport in Florida; and the Company’s proportionate share of the $1.3 billion Connecticut River Bridge Replacement project in Connecticut.

Consolidated backlog as of December 31, 2024 was $18.7 billion, up 84% compared to $10.2 billion as of December 31, 2023, and set a new all-time record that far exceeded the previous record backlog of $14.0 billion reported for the third quarter of 2024. Backlog as of December 31, 2024 for all three segments also set new all-time records. As of December 31, 2024, the mix of backlog by segment was 47% for Civil, 38% for Building and 15% for Specialty Contractors, compared to 42% for Civil, 41% for Building and 17% for Specialty Contractors at the end of 2023.

Table of Contents

Most projects in the Civil segment’s backlog typically convert to revenue over a period of three to five years and in the Building and Specialty Contractors segments over a period of one to three years. We estimate that approximately $4.5 billion, or approximately 24%, of our backlog as of December 31, 2024 will be recognized as revenue in 2025.

The following table presents the changes in backlog in 2024:

_____________________________________________________________________________________________________________

(a)New awards consist of the original contract price of projects added to our 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 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 is highly favorable, particularly due to strong new award bookings in 2024, as well as other significant new awards that have been and could be booked in 2025. For example, the Company announced in the first quarter of 2025 the award of the $1.18 billion Manhattan Tunnel project in New York and $232 million for several owner-authorized scope options on the Apra Harbor Waterfront Repairs project in Guam. The Company plans to bid various other large new projects in 2025, including the multi-billion-dollar Midtown Bus Terminal Replacement project in New York that is expected to bid in March 2025. Many of the Company’s newer projects are design-build projects that have an initial design phase over the first six to eighteen months during which smaller revenue and earnings are generated prior to the start of a multi-year construction phase that generates substantially larger revenue and earnings. Revenue growth could be impacted 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.

Nationally, support for transportation-related ballot measures has remained high over the last decade. Since 2014, voters in 43 states approved 84 percent of nearly 3,000 state and local measures on general election ballots. The largest of these was in Los Angeles County, where in 2016 Measure M, a half-cent sales tax increase, was approved 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, in the November 2024 elections, voters approved 77 percent of 370 transportation funding measures on state and local ballots throughout the country. These measures are expected to generate an estimated $41.4 billion in new and renewed funding for roads, bridges, rail and other infrastructure. For the first time in four years, interest rates were lowered in September 2024, and some economists expect further rate reductions 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 Law 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 Bipartisan Infrastructure 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.

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:

Revenue for 2024 increased 12% compared to 2023, primarily due to a net increase in project execution activities driven by certain large mass-transit projects in California and Hawaii, 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 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 is appealing.

Income from construction operations for 2024 decreased $60.3 million compared to 2023. The decrease was primarily due to unfavorable adjustments in 2024, including $101.6 million in the third quarter pertaining to the aforementioned unexpected adverse arbitration decision on a legacy dispute related to a completed bridge project in California, which the Company is appealing; a temporary non-cash impact of $31.8 million in the fourth quarter for a project on the West Coast, which primarily resulted from significant changes that have been negotiated, or are being negotiated, that carry lower margin (and lower risk) that reduced the project’s percentage of completion and overall margin percentage; $17.4 million due to an unfavorable legal ruling on a completed highway project in Virginia; and $15.1 million due to changes in estimates on an otherwise profitable mass-transit project in California that is nearly complete. The decrease was partially offset by contributions related to the net increase in project execution activities discussed above that totaled $70.4 million, as well as a favorable adjustment in 2024 of $18.4 million due to a settlement of a claim associated with a completed highway tunneling project in the western United States.

The decrease in income from construction operations was also partially offset by a net favorable impact of $9.6 million due to the absence of the following prior-year adjustments: 1) a net unfavorable adjustment of $14.4 million due to the aforementioned settlement that affected multiple components of a mass-transit project in California; 2) an unfavorable adjustment of $14.2 million due to changes in estimates on the Civil segment’s portion of a completed transportation project in the Northeast primarily related to the settlement of certain change orders, changes in estimates associated with recent negotiations and incremental cost incurred during project closeout; and 3) net favorable adjustments totaling $19.0 million for a project on the West Coast.

Operating margin was 6.5% for 2024 compared to 10.5% in 2023. The decrease in operating margin for 2024 was primarily due to the aforementioned unfavorable adjustment of $101.6 million related to the unexpected adverse arbitration decision on a legacy dispute related to a completed bridge project in California.

New awards in the Civil segment totaled $6.7 billion in 2024 compared to $1.7 billion in 2023. Significant new awards and contract adjustments in 2024 included the $1.66 billion City Center Guideway and Stations project in Hawaii; the $1.13 billion Newark AirTrain Replacement project in New Jersey; the $1.1 billion Kensico-Eastview Connection Tunnel project in New York; the Civil segment’s share of both the $3.76 billion Manhattan Jail project and the $2.95 billion Brooklyn Jail project, both in New York; $479 million of additional funding for certain mass-transit projects in California; $331 million for the Apra Harbor Waterfront Repairs project in Guam; and the Company’s proportionate share of the $1.3 billion Connecticut River Bridge Replacement project in Connecticut.

New awards and contract adjustments in 2023 included $788 million of additional funding for certain mass-transit projects in California; a $222 million military facilities project at Tinian International Airport in the Commonwealth of the Northern Mariana Islands; and $127 million of additional funding for a mass-transit project in Minnesota.

Table of Contents

Backlog for the Civil segment was $8.8 billion as of December 31, 2024, up 108% compared to $4.2 billion as of December 31, 2023, and set a new all-time record for the segment. 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 Bipartisan Infrastructure Law, 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 loss from construction operations for the Building segment are summarized as follows:

Revenue for 2024 increased 24% compared to 2023, with the growth driven by increased project execution activities on various healthcare and educational facility projects in California and a detention facility project in New York with substantial scope of work remaining, 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.

Loss from construction operations for 2024 was $24.1 million compared to a loss of $91.2 million for 2023. The significant improvement was principally due to the absence of prior-year unfavorable adjustments, including 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, a $14.6 million unfavorable adjustment on a government building project in Florida primarily due to increased costs associated with an external subcontractor, and a $14.2 million unfavorable adjustment due to changes in estimates on the Building segment’s portion of the aforementioned completed transportation project in the Northeast. The improvement was also due to contributions related to the increased project execution activities discussed above that totaled $26.6 million, partially offset by the impact of unfavorable adjustments in 2024 of $25.9 million on the government building project in Florida mentioned above, which is now nearing completion, primarily due to increased costs associated with external subcontractors and resolution of certain delay change orders, and $20.0 million associated with the settlement of a legacy dispute related to a completed government facility project in Florida.

Operating margin was (1.5)% in 2024 compared to (7.0)% in 2023. The increase in operating margin was driven by the factors mentioned above that drove the improved revenue and loss from construction operations.

New awards in the Building segment totaled $4.5 billion in 2024 compared to $3.3 billion in 2023. Significant new awards and contract adjustments in 2024 included the Building segment’s portion of the $3.76 billion Manhattan Jail project in New York (which includes a substantial amount of electrical and mechanical scope of work that is expected to be performed by the Specialty Contractors segment); a $1.4 billion healthcare campus project in California; $449 million for two healthcare facility projects in California; and a $229 million airport terminal connectors project at Fort Lauderdale-Hollywood International Airport in Florida.

Certain Building segment end markets, such as 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 elevated interest rates, could continue to result in delayed or canceled Building segment project opportunities, particularly in the corporate office end market.

New awards and contract adjustments in 2023 included the $2.95 billion Brooklyn Jail project in New York (which includes more than $630 million of electrical and mechanical subcontract work to be performed by the Specialty Contractors segment) and $287 million of additional funding for two large healthcare projects in California.

Backlog for the Building segment was $7.0 billion as of December 31, 2024, up 68% compared to $4.2 billion as of December 31, 2023, and set a new all-time record for the segment, with the increase largely driven by the award of the Manhattan Jail project mentioned above. 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 preconstruction phase, with only a small amount of current backlog recorded for them. Some of these projects are soon expected to advance into the construction phase, and we anticipate that we will book significant additional backlog for these projects as a result.

Table of Contents

Specialty Contractors Segment

Revenue and loss from construction operations for the Specialty Contractors segment are summarized as follows:

Revenue for 2024 decreased 15% compared to 2023, principally due to reduced project execution activities on various electrical and mechanical projects in New York and Florida and an industrial facility project in Arizona, all of which are completed or nearing completion. The decrease was partially offset by the absence of certain prior-year unfavorable adjustments described in the paragraph below.

Loss from construction operations for 2024 was $103.3 million compared to a loss of $144.8 million for 2023. The improvement was primarily due to the absence of certain prior-year unfavorable adjustments, including $62.2 million of unfavorable non-cash adjustments due to changes in estimates on the electrical and mechanical scope of a completed transportation project in the Northeast associated with changes in the expected recovery on certain unapproved change orders resulting from ongoing negotiations; a non-cash charge of $24.7 million on an educational facilities project in New York that resulted from an adverse court ruling; an unfavorable adjustment of $16.9 million on a multi-unit residential project in New York due to changes in estimates resulting from incremental costs to complete the project and ongoing negotiations on unapproved change orders; and 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. The improvement was partially offset by certain 2024 unfavorable adjustments on several completed projects due to the impact of judgments and settlements totaling $57.2 million, including $17.7 million due to an unfavorable judgment on a completed mass-transit project in California and certain other adjustments that were individually immaterial. The improvement was also offset by the reduced project execution activities discussed above.

Operating margin was (17.5)% in 2024 compared to (20.9)% in 2023. The change in operating margin was mainly attributable to the aforementioned factors that drove the lower loss from construction operations in 2024.

New awards in the Specialty Contractors segment totaled $1.7 billion in 2024 compared to $1.1 billion in 2023. The most significant new awards and contract adjustments in 2024 included the Specialty Contractors segment’s electrical and mechanical scope of work booked as part of the Manhattan Jail project discussed above, two electrical projects in New York collectively valued at $195 million and a $64 million electrical project in Connecticut.

New awards in 2023 included more than $630 million of electrical and mechanical subcontract work to be performed on the Brooklyn Jail project in New York; a $67 million communications systems integration project in New York; and the Central District Wastewater Treatment Plant electrical project in Florida, valued at more than $40 million.

Backlog for the Specialty Contractors segment was $2.8 billion as of December 31, 2024, up 62% compared to $1.7 billion as of December 31, 2023, and set a new all-time record for the segment. 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 $110.2 million in 2024 compared to $75.2 million in 2023. The increase in corporate general and administrative expenses in 2024 compared to 2023 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 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.

Table of Contents

Other Income, Net, Interest Expense and Income Tax Benefit

Other income, net increased by $2.7 million in 2024 compared to 2023 primarily due to an increase in interest income associated with a larger amount of cash on hand in 2024 compared to the prior year.

Interest expense increased $3.9 million in 2024 compared to 2023. The Company expects interest expense to decrease in 2025 and beyond as a result of the paydown of $245.3 million of the outstanding Term Loan B during 2024, as well as the repayment of the remaining $121.9 million Term Loan B balance in the first quarter of 2025, as discussed further in Liquidity and Capital Resources. Interest expense on the Term Loan B amounted to $36.9 million and $41.9 million for 2024 and 2023, respectively.

The effective income tax rate was 29.3% for 2024 compared to 30.1% for 2023. The items that caused a lower effective tax rate in 2024 as compared to 2023 were primarily non-deductible compensation expenses and an increase in the valuation allowance, offset by higher state income taxes. For a further discussion of income taxes, refer to Note 5 of the Notes to Consolidated Financial Statements.

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 December 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 record cash flow from operations in 2024 which was greater than the previous record set in 2023, as discussed below in Cash and Working Capital. This represented the third consecutive year in which we generated record cash flows from operations. We expect strong operating cash flow to continue in 2025 based on projected cash collections, both from project execution activities and the resolution of outstanding claims and change orders. We utilized some of our record cash flow from operations in 2024 to repay a total of $245.3 million of our outstanding Term Loan B during 2024. During the first quarter of 2025, we voluntarily repaid the remaining $121.9 million outstanding balance of the Term Loan B. 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 $455.1 million as of December 31, 2024 compared to $380.6 million as of December 31, 2023. Cash immediately available for general corporate purposes was $265.6 million and $145.1 million as of December 31, 2024 and 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 $149.1 million as of December 31, 2024 compared to $144.4 million as of December 31, 2023. Restricted cash and restricted investments at December 31, 2024 were primarily held to secure insurance-related contingent obligations and deposits.

During the year ended December 31, 2024, net cash provided by operating activities was $503.5 million, compared to $308.5 million in 2023, representing an increase of $195.1 million, or 63%. The operating cash flow for 2024 was the largest result for any year since the merger between Tutor-Saliba Corporation and Perini Corporation in 2008, exceeding the previous records achieved in 2023 and 2022. The record operating cash flow in 2024 was primarily due to a decrease in costs and estimated earnings in excess of billings (“CIE”) largely associated with the resolution of various legacy disputed matters, an increase in accounts payable resulting from the timing of payments to subcontractors and vendors, and an increase in billings in excess of costs and estimated earnings (“BIE”) primarily due to advanced payments on newer projects for mobilization and other initial project costs, partially offset by cash utilized by earnings sources. During the year ended December 31, 2023, net cash provided by operating activities was $308.5 million 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 improved collection activity, as reflected by a decrease in CIE and accounts receivable, and an increase in BIE.

As noted above, cash flow from operating activities increased $195.1 million when comparing 2024 with 2023. The increase was primarily driven by a larger decrease in investments in working capital and a lower use of cash from earnings sources in

2024 compared to the prior year. Both periods benefited from strong cash collections related to project execution activities on newer and ongoing projects, as well as significant cash collections associated with the resolution of previously disputed matters.

Net cash used in investing activities during 2024 was $40.7 million, which was primarily due to the acquisition of property and equipment (i.e., capital expenditures) totaling $37.4 million and net cash used in investment transactions of $8.0 million, partially offset by proceeds from the sale of property and equipment of $4.8 million. Net cash used in investing activities during 2023 was $78.2 million, which was primarily due to the acquisition of property and equipment totaling $53.0 million and net cash used in investment transactions of $35.4 million, partially offset by proceeds from the sale of property and equipment of $10.1 million.

Net cash used in financing activities during 2024 was $393.3 million, which was primarily driven by a $354.6 million net repayment of debt (including the 2024 Senior Notes issuance of $400 million and the 2017 Senior Notes redemption of $500 million, as well as additional principal prepayments 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 year and $23.3 million of cash distributions to noncontrolling interests, partially offset by $15.2 million of cash contributions from noncontrolling interests. Net cash used in financing activities during 2023 was $109.4 million, which was primarily driven by net repayment of borrowings of $61.7 million and $46.5 million of cash distributions to noncontrolling interests, partially offset by $2.0 million of cash contributions from noncontrolling interests.

As of December 31, 2024, we had working capital of $1.0 billion, a ratio of current assets to current liabilities of 1.41 and a ratio of debt to equity of 0.46 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.

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 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 December 31, 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 were $121.9 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 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, which was due by the first week of April 2024 and paid in February 2024. In addition to the mandatory prepayment discussed above, the Company made voluntary, early prepayments totaling $150.0 million of the Term Loan B during 2024. During the first quarter of 2025, the Company voluntarily repaid the remaining $121.9 million outstanding balance of the Term Loan B.

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 year ended December 31, 2024 were approximately 10.0% and 11.8%, respectively. At December 31, 2024, the borrowing rates on the Term Loan B and the Revolver were 9.2% and 10.8%, respectively. For more information regarding the terms of our 2020 Credit Agreement, refer to Note 7 of the Notes to Consolidated Financial Statements.

Table of Contents

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:

As amended, 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 December 31, 2024, we were in compliance and expect to continue to be in compliance with the covenants under the 2020 Credit Agreement.

Equipment Financing and Mortgages

The Company has certain loans entered into for the purchase of specific property, plant and equipment and secured by the assets purchased. The aggregate balance of equipment financing loans was approximately $19.3 million and $26.4 million at December 31, 2024 and 2023, respectively, with interest rates ranging from 2.54% to 7.32% with equal monthly installment payments over periods up to 5 years. The aggregate balance of mortgage loans was approximately $5.8 million and $8.4 million at December 31, 2024 and 2023, respectively, with interest rates of SOFR plus 2.00% and monthly installment payments over periods up to 10 years.

Contractual Obligations

Our contractual obligations and commitments as of December 31, 2024 include:

•Debt obligations of $556.1 million (of which $24.1 million are due in 2025) and interest payments of $221.1 million (of which $53.4 million are due in 2025) based on rates in effect as of December 31, 2024. See Note 7 of the Notes to Consolidated Financial Statements for further detail of our debt and the timing of expected future principal and interest payments.

•Operating lease obligations of $67.1 million (of which $11.0 million are due in 2025). See Note 9 of the Notes to Consolidated Financial Statements for further detail of our lease obligations and the timing of expected future payments.

Critical Accounting Estimates

Our discussion and analysis of our financial condition and results of operations is based upon our Consolidated Financial Statements, which have been prepared in accordance with GAAP. Our significant accounting policies are described in Note 1 of the Notes to Consolidated Financial Statements. The preparation of the Consolidated Financial Statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. Estimates are based on information available through the date of the issuance of the financial statements; accordingly, actual results in future periods could differ from these estimates. Significant judgments and estimates used in the preparation of the Consolidated Financial Statements apply to the following critical accounting policies:

Method of Accounting for Contracts — Contract revenue is recognized over time using the cost-to-cost method which measures progress towards completion based on the ratio of contract costs incurred to date compared to total estimated costs for each performance obligation. The estimates used in accounting for contracts with customers require judgment and assumptions regarding both future events and the evaluation of contingencies such as the impact of change orders, liability claims, other contract disputes, the achievement of contractual performance standards and potential variances in project schedule and costs. Changes to the total estimated contract cost, either due to unexpected events or revisions to management’s initial estimates, for a given project are recognized in the period in which they are determined.

In certain instances, we provide guaranteed completion dates and/or achievement of other performance criteria. Failure to meet schedule or performance guarantees could result in unrealized incentive fees and/or liquidated damages. In addition, depending on the type of contract, unexpected increases in contract cost may be unrecoverable, resulting in total cost exceeding revenue realized from the projects. The Company generally provides limited warranties for work performed, with warranty periods

29

Table of Contents

typically extending for a limited duration following substantial completion of the Company’s work on a project. Historically, warranty claims have not resulted in material costs incurred.

Claims arising from construction contracts have been made against the Company by customers, and the Company has made claims against customers for costs incurred in excess of current contract provisions. The Company recognizes revenue for claims as variable consideration in accordance with Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers (“ASC 606”). Assumptions as to the occurrence of future events and the likelihood and amount of variable consideration are made during the contract performance period. Estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of anticipated performance and all information (historical, current and forecasted) that is reasonably available to management. Estimated amounts are only included in the transaction price 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. Back charges to suppliers or subcontractors are recognized as a reduction of cost when it is determined that recovery of such cost is probable and the amounts can be reliably estimated. Disputed back charges are recognized when the same requirements described above for variable consideration have been satisfied.

See Executive Overview and Results of Segment Operations sections for further discussion and quantification of material charges related to changes in estimates resulting from legal judgments or decisions, settlements and other project charges.

Construction Joint Ventures — Certain contracts are executed through joint ventures. The arrangements are often formed for the execution of single contracts or projects and allow the Company to share risks and secure specialty skills required for project execution.

In accordance with ASC 810, Consolidation (“ASC 810”) the Company assesses its joint ventures at inception to determine if any meet the qualifications of a variable interest entity (“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 the joint venture is a VIE.

The Company also evaluates whether it is the primary beneficiary of each VIE and consolidates the VIE if the Company has both (a) the power to direct the economically significant activities of the entity and (b) the obligation to absorb losses of, or the right to receive benefits from, the entity 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 whether it qualifies as the primary beneficiary. The Company also considers all parties that have direct or implicit variable interests when determining whether it is the primary beneficiary. When the Company is determined to be the primary beneficiary, the VIE is consolidated. In accordance with ASC 810, management’s assessment of whether the Company is the primary beneficiary of a VIE is performed continuously.

For construction joint ventures that do not need to be fully consolidated but qualify for the equity method of accounting, the Company accounts for its interest in the joint ventures using the proportionate consolidation method, whereby the Company’s proportionate share of the joint ventures’ assets, liabilities, revenue and cost of operations are included in the appropriate classifications in the Company’s consolidated financial statements. Intercompany balances and transactions are eliminated. See Note 1(b) and Note 13 of the Notes to Consolidated Financial Statements for additional discussion regarding VIEs.

Recoverability of Goodwill — Goodwill represents the excess of amounts paid over the fair value of net assets acquired from an acquisition. In order to determine the amount of goodwill resulting from an acquisition, we perform an assessment to determine the value of the acquired company's tangible and identifiable intangible assets and liabilities. In our assessment, we determine whether identifiable intangible assets exist, which typically include backlog, customer relationships and trade names.

We test goodwill for impairment annually as of October 1 of each year. This test requires us to estimate the fair value of each reporting unit carrying goodwill using income and market approaches, and to compare the calculated fair value of each reporting unit to its carrying value, which is equal to the reporting unit’s net assets. If the calculated fair value of a reporting unit is less than its carrying value, we recognize an impairment charge equal to the difference.

30

Table of Contents

The impairment evaluation process requires assumptions that are subject to a high degree of judgment such as revenue growth rates, profitability levels, discount rates, industry market multiples and weighted-average cost of capital. Changes in these assumptions would impact the results of our impairment tests.

During interim periods, including those subsequent to the Company’s October 1 annual test date, we evaluate events and circumstances, including, but not limited to, an examination of macroeconomic conditions, cost factors, overall financial performance by each reporting unit, other relevant entity-specific events, and trends in the stock prices of our Company and peers to determine if such factors indicate that it is likely that the goodwill for one or more of our reporting units is impaired, thus warranting the performance of a quantitative impairment test sooner than the fourth quarter of the year.

During the fourth quarter of 2024, we conducted our annual goodwill impairment test and determined that goodwill was not impaired since the estimated fair value of the Civil reporting unit exceeded its net book value by a significant amount. However, there is a risk of goodwill impairment if future events are less favorable than what we assumed or estimated in our impairment analysis.

The Company has considered relevant events and circumstances since the annual goodwill impairment test, including, but not limited to, an examination of macroeconomic conditions, industry and market conditions, cost factors, overall financial performance by each reporting unit, other relevant entity-specific events, and trends in the stock prices of the Company and its peers. In considering the totality of qualitative factors known as of the reporting date, we determined that no triggering events occurred or circumstances changed since our October 1, 2024 annual test that would more likely than not reduce the fair value of the Civil reporting unit below its carrying amount. We will continue to monitor events occurring or circumstances changing which may suggest that goodwill should be reevaluated. These events and circumstances include, but are not limited to, changes in the overall financial performance of the Civil reporting unit and other quantitative and qualitative factors specific to the Civil reporting unit which indicate potential triggering events that would more likely than not reduce the fair value of the Civil reporting unit below its carrying amount.

Executive Overview

COVID-19 Update

During 2020 and 2021, COVID-19 caused shut-downs or significant reductions in the operations of various courts and arbitrations, which hindered the Company’s ability to resolve disputes related to unapproved work and resulted in the need for the Company to temporarily fund certain project costs that historically would have been promptly negotiated, billed to and collected from customers. This negative impact from the pandemic lessened in 2022 and remained low in 2023, with certain previously delayed disputes finally resolved and other settlement conferences and trials progressing or scheduled to be addressed soon. Consequently, the Company has made and expects to continue to make substantial progress in the resolution of various disputes in 2024 and 2025.

Through the latter part of 2021, the pandemic also significantly delayed the bidding and awarding of various large prospective civil projects, which affected the volume and timing of our new awards. The follow-on impact was a substantial but temporary reduction in our backlog, revenue and income from construction operations over the past three years. For example, the Company’s consolidated backlog had been near a record level at $11.2 billion as of December 31, 2019, just prior to the onset of COVID-19, but declined in each subsequent year through 2022, and was $7.9 billion as of December 31, 2022, a 29% decrease compared to the end of 2019. Similarly, revenue declined from $5.3 billion in 2020 to $3.8 billion and $3.9 billion in 2022 and 2023, respectively, though there were other factors that contributed to the revenue decline since 2020 as discussed below. The current impacts of the pandemic on new project awards have lessened, as evidenced by the recent strong growth in the Company’s backlog to $10.2 billion as of December 31, 2023, due primarily to new awards in 2023, the largest of which was the $2.95 billion Brooklyn Jail project. However, the follow-on impact from delayed project bids and large contract awards has continued to have a negative impact on our revenue and profitability. In addition, many of our state and local government customers’ revenue sources were negatively impacted by the pandemic due to a reduction of commuter and business travel. Despite improved commuter and business travel conditions, the significant revenue reductions experienced by these customers have, in some cases, continued to adversely impact their timely payment to the Company for amounts due, although these impacts moderated in 2023.

Operating Results

Consolidated revenue for 2023 was $3.9 billion, up slightly compared to $3.8 billion for 2022. Higher revenue in the Civil and Building segments was offset by lower revenue in the Specialty Contractors segment, as discussed in more detail below in Results of Segment Operations. In addition, customer budgetary constraints previously induced by COVID-19, combined with certain political and other factors, resulted in the Company not being awarded certain Civil segment projects over the last few years totaling more than $10.0 billion despite having been the low or preferred bidder. Not being awarded these projects also impacted revenue for both 2022 and 2023, and most of these projects are now expected to be re-bid in 2024. Furthermore, the Company was unsuccessful in its pursuit of certain large prospective Civil segment projects in the second half of 2021, which also unfavorably impacted revenue in 2022 and 2023.

Table of Contents

Loss from construction operations for 2023 was $114.6 million compared to $204.8 million for 2022. In 2022, the Company implemented changes to its business strategy, primarily with respect to collections and operations in its Specialty Contractors segment in New York. These changes were implemented in response to COVID-19’s negative impacts on the Company’s net working capital, cash collections, and liquidity, as discussed above, the Company’s desire to reduce its legal expenses and allow management to focus more on the successful execution of projects and on growing the business, and in consideration of certain unfavorable legal judgments and decisions in recent years and the possibility that future litigation and arbitration, particularly in New York, could have a similar negative impact. Specifically, in the latter part of 2022, management increasingly focused on expeditiously negotiating settlements of certain Specialty Contractors segment disputes in New York to accelerate the collection of cash and reduce the risk and uncertainty associated with continued lengthy and costly litigation, arbitration proceedings and settlement negotiations. In implementing this change in collections strategy, management concluded that significant concessions would be required in a number of disputes to facilitate settlements. Ultimately, the Company agreed to settle these disputes for amounts less than what had previously been estimated and might have been obtained if the disputes had been litigated to conclusion. This shift in collections strategy contributed to the significant decline in income from construction operations in 2022. In 2023, as dispute resolution processes progressed on certain projects (not just limited to the Specialty Contractors segment in New York), the Company continued to focus on expediting settlements, which contributed to the strong cash collections, but also to some of the loss from construction operations in 2023. The strong cash collections in 2023 enabled the Company to pay down certain debt, and the Company believes that its improved liquidity will be beneficial to its ability to refinance the 2017 Senior Notes (and possibly other outstanding indebtedness).

The reduced loss from construction operations in 2023 was primarily due to a lower amount of net unfavorable impacts in 2023 as compared to 2022, including: 1) certain adverse legal judgments or decisions that had net unfavorable impacts totaling $122.2 million in 2023 compared to $147.8 million in 2022; and 2) various settlements that had a net favorable impact of $8.4 million in 2023 compared to a net unfavorable impact of $85.4 million in 2022. The improvement was partially offset by higher net unfavorable impacts in 2023 related to various changes in estimates for project charges, net of positive impacts from improved productivity and efficiencies on certain projects, which had an aggregate net negative impact of $117.2 million in 2023 compared to $96.8 million in 2022. Also contributing to the change between 2023 and 2022 were temporary aggregate negative project adjustments of $79.2 million in 2023 compared to $119.7 million in 2022 due to increases in unapproved work on various projects, all of which are expected to reverse themselves over the remaining lives of the projects. The material project adjustments associated with these factors are discussed below.

Adverse legal judgments or decisions during 2023 included an adverse legal ruling on a completed mixed-use project in New York, which resulted in a non-cash charge of $83.6 million, of which $72.2 million impacted the Building segment and $11.4 million impacted the Specialty Contractors segment, and a $24.7 million non-cash charge that resulted from an adverse court ruling on a Specialty Contractors segment educational facilities project in New York.

Adverse legal judgments or decisions during 2022 included a $43.2 million non-cash impact related to the electrical component of a completed mass-transit project in New York in the Specialty Contractors segment, a $26.2 million unfavorable non-cash impact due to the reversal on appeal of a previously favorable lower-court ruling related to a completed Civil segment highway project in the Northeast, a $25.5 million non-cash impact related to a completed Civil segment bridge project in New York, a $17.8 million non-cash impact associated with the partial reversal by an appellate court of previously awarded legal damages related to a completed electrical project in New York in the Specialty Contractors segment, an $11.3 million impact related to a Building segment hospitality project in Florida and a $10.0 million non-cash impact related to a Civil segment mass-transit project in New York.

Settlements during 2023 had a net favorable impact of $8.4 million, as discussed above, which included favorable adjustments totaling $58.1 million resulting from the settlement of change orders and changes in estimates due to improved performance on a Civil segment project on the West Coast. This favorable impact was mostly offset by the net unfavorable impacts from other settlements including the net unfavorable impact from a settlement that affected multiple components of a Civil segment mass-transit project in California. This settlement 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 to one component of the project that is nearing completion, partially offset by a favorable adjustment of $8.8 million on the other component of the project that has substantial scope of work remaining. The net unfavorable impact in 2023 from these two adjustments is expected to be mitigated by the increased profit generated from future work on the project. Other settlements in 2023 included a $13.1 million unfavorable non-cash impact (split evenly between the Civil and Building segments) related to a completed transportation project in the Northeast, a $9.4 million unfavorable adjustment on a completed Specialty Contractors mass-transit project in California and the net unfavorable impact of various other settlements that were individually immaterial.

Settlements during 2022 had an aggregate net negative impact of $85.4 million, as noted above, which included unfavorable impacts related to certain Specialty Contractors segment projects in New York that collectively totaled $32.9 million, one of

which negatively impacted profitability by $11.3 million, with the remainder of the negative impacts in the Specialty Contractors segment composed of unfavorable settlements that were individually immaterial. Other settlements in 2022 included a $16.2 million unfavorable non-cash impact related to a long-disputed, completed Civil segment project in Maryland, a $13.4 million unfavorable non-cash impact (split evenly between the Civil and Building segments) related to a completed transportation project in the Northeast, an $11.6 million unfavorable non-cash impact related to a Civil segment mass-transit project in California, as well as the unfavorable impact of various other settlements that were individually immaterial, partially offset by a $12.7 million favorable impact related to a Civil segment bridge project in the Midwest.

Other significant project charges of $117.2 million in 2023 included $62.2 million of unfavorable non-cash adjustments due to changes in estimates on the 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; an unfavorable adjustment of $16.9 million on a Specialty Contractors segment multi-unit residential project in New York due to changes in estimates resulting from incremental costs to complete the project and ongoing negotiations on unapproved change orders; a $14.9 million unfavorable adjustment due to changes in estimates due to recent negotiations and incremental cost incurred during project closeout (split evenly between the Civil and Building segments) on the same completed transportation project in the Northeast discussed above; a $14.6 million unfavorable adjustment on a Building segment government building project in Florida primarily due to increased costs associated with an external subcontractor; unfavorable adjustments of $12.8 million on a completed Civil segment highway project in Virginia due to changes in estimates that resulted from progress in the dispute resolution process; and the net favorable impact of changes in estimates on various other projects that were individually immaterial. All of the project charges were due to changes in facts and circumstances that were identified in 2023.

Significant project charges in 2022 of $96.8 million included a $36.1 million charge due to unfavorable adjustments related to the unforeseen cost of project close-out issues, remediation work, extended project supervision and associated labor inefficiencies on the electrical (Specialty Contractors segment) component of a transportation project in the Northeast; an $18.0 million charge related to similar project close-out issues (split evenly between the Civil and Building segments) on the same transportation project in the Northeast; a $13.1 million charge due to inefficiencies and cost overruns on a Civil segment mass-transit project in California; and $11.1 million of charges related to close-out discussions for a mechanical project in New York in the Specialty Contractors segment, as well as the net unfavorable impact of changes in estimates on numerous other projects that were individually immaterial. In certain cases, the changes in facts and circumstances resulted in changes in estimates to the expected recoveries for certain disputed matters, which were identified as part of the implementation of a new collections strategy in the latter part of 2022 and were primarily related to the Specialty Contractors segment in New York. All of the project charges were due to changes in facts and circumstances that were identified in 2022.

Temporary aggregate negative project adjustments referred to above for 2023 of $79.2 million included a temporary unfavorable non-cash impact of $40.7 million resulting from the successful negotiation of significant lower margin (and lower risk) change orders on a Civil segment project on the West Coast. These approved change orders increased the project’s overall estimated profit but reduced the project’s percentage of completion and overall margin percentage. This temporary reduction to earnings is expected to reverse itself over the remaining life of the project. The remaining amount of temporary negative project adjustments were individually immaterial and were due to growth in unapproved change orders on various projects that reduced the projects’ percentage of completion and profit margin, which are also expected to reverse over the remaining lives of the projects.

The 2022 temporary aggregate negative project adjustments of $119.7 million referred to above included a temporary unfavorable non-cash impact of $38.8 million resulting from the successful negotiation of significant lower margin (and lower risk) change orders on the same Civil segment project on the West Coast. These approved change orders increased the project’s overall estimated profit but reduced the project’s percentage of completion and overall margin percentage. As indicated above, this temporary reduction to earnings is expected to reverse itself over the remaining life of the project. The remaining amount of temporary negative project adjustments was due to growth in unapproved change orders on various projects that reduced the projects’ percentage of completion and profit margin, which are also expected to reverse over the remaining lives of the projects. The largest portion of this remaining amount was a $10.1 million temporary unfavorable impact on the electrical (Specialty Contractors segment) component of a transportation project in the Northeast.

The effective income tax rate for 2023 was 30.1% compared to 28.1% for 2022. See Corporate, Tax and Other Matters below for a discussion of the change in the effective tax rate.

Diluted loss per common share for 2023 was $3.30 compared to diluted loss per common share of $4.09 for 2022. The change in 2023 was primarily due to the factors discussed above that led to the change in loss from construction operations.

Consolidated new awards in 2023 were $6.1 billion compared to $3.5 billion in 2022. The Building and Civil segments were the primary contributors to the new award activity in 2023. Significant new awards and contract adjustments in 2023 included

the $2.95 billion Brooklyn Jail project in New York; $788 million of additional funding for certain mass-transit projects in California; $287 million of additional funding for two large health care projects in California; a $222 million military facilities project at Tinian International Airport in the Commonwealth of the Northern Mariana Islands; and $127 million of additional funding for a mass-transit project in Minnesota.

Consolidated backlog as of December 31, 2023 was $10.2 billion, up 28% compared to $7.9 billion as of December 31, 2022. As of December 31, 2023, the mix of backlog by segment was 42% for Civil, 41% for Building and 17% for Specialty Contractors, compared to 56% for Civil, 28% for Building and 16% for Specialty Contractors at the end of 2022.

Most projects in the Civil segment’s backlog typically convert to revenue over a period of three to five years and in the Building and Specialty Contractors segments over a period of one to three years. We estimate that approximately $4 billion, or approximately 40%, of our backlog as of December 31, 2023 will be recognized as revenue in 2024.

The following table presents the changes in backlog in 2023:

_____________________________________________________________________________________________________________

(a)New awards consist of the original contract price of projects added to our 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 2 of the Notes to 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 in 44 states have approved 85% of nearly 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. Despite numerous increases since March 2022, interest 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. Lower interest rates would likely support additional demand for continued infrastructure spending. In contrast, should interest rates climb further, they could reach levels that may negatively impact demand, especially for certain types of Building segment projects that tend to be more economically sensitive, such as commercial offices and tenant improvement projects.

The BIL 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, 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.

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:

Revenue for 2023 increased 9% compared to 2022, primarily due to the absence of certain prior-year unfavorable adjustments, as further discussed below, partially offset by the unfavorable impacts in 2023 from various project adjustments, also discussed below. In addition, revenue growth was also impacted by increased project execution activities on a mass-transit project in California and various projects in Guam and the Northern Mariana Islands, largely offset by reduced project execution activities on the tunneling portion of another mass-transit project in California that is substantially complete. Revenue for both years was also adversely impacted by the follow-on impacts of COVID-19, which delayed bidding activities and awards of certain new projects during 2020 and much of 2021 and continued to negatively impact revenue for both 2022 and 2023. Furthermore, revenue for both periods was adversely impacted by certain projects totaling more than $10.0 billion for which the Company was the low or preferred bidder but no contract was awarded over the last few years due to COVID-19-induced customer budget constraints, as well as the Company’s lack of success in its pursuit of certain large prospective Civil segment projects in the second half of 2021.

Income from construction operations for 2023 increased $177.5 million compared to 2022. The change was favorably impacted by current-year net favorable adjustments totaling $19.0 million for a project on the West Coast, primarily resulting from the favorable impact of $58.1 million on the settlement of change orders and changes in estimates due to improved performance, partially offset by a temporary unfavorable non-cash impact of $40.7 million 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. The change was also favorably impacted by contributions from higher volume from this project and the other projects discussed in the paragraph above. Also contributing to the favorable change was the absence of significant prior-year unfavorable adjustments including the temporary unfavorable impact of $38.8 million resulting from the successful negotiation of significant lower margin (and lower risk) change orders on the same project on the West Coast (where the temporary reduction to earnings is expected to reverse itself over the remaining life of the project); the $26.2 million unfavorable non-cash impact related to a completed highway project in the Northeast due to the reversal on appeal of a previously favorable lower-court ruling; the $25.5 million unfavorable non-cash impact related to the adverse legal judgment on a dispute related to a completed bridge project in New York; the $16.2 million unfavorable non-cash impact related to the settlement of a long-disputed, completed project in Maryland; the $13.1 million charge due to inefficiencies and cost overruns and the unfavorable non-cash settlement impact of $11.6 million, both related to another mass-transit project in California; and the $10.0 million non-cash impact related to an unfavorable adjustment resulting from an adverse legal decision on a mass-transit project in the Northeast. These prior-year unfavorable impacts were partially offset by a prior-year favorable project close-out adjustment of $12.7 million on a bridge project in the Midwest. In addition, income from construction operations for both 2023 and 2022 was similarly unfavorably impacted by adjustments due to changes in estimates on the Civil segment’s portion of a completed transportation project in the Northeast primarily due to the settlement of certain change orders, changes in estimates due to recent negotiations and incremental cost incurred during project closeout ($14.2 million in 2023 and $15.7 million in 2022).

The favorable changes in income from construction operations described above were partially offset by a settlement in 2023 that impacted multiple components of a mass-transit project in California. This settlement 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 to one component of the project that is nearing completion, partially offset by a favorable adjustment of $8.8 million on the other component of the project that has substantial scope of work remaining. The net unfavorable impact in 2023 from these two adjustments is expected to be mitigated by the increased profit generated from future work on the project. The change in income from construction operations was also adversely impacted by unfavorable

adjustments of $12.8 million on a completed highway project in Virginia due to changes in estimates that resulted from progress in the dispute resolution process.

Operating margin was 10.5% for 2023 compared to 1.2% in 2022. The increase in operating margin for 2023 was primarily due to the factors discussed above that drove the increase in income from construction operations.

New awards in the Civil segment totaled $1.7 billion in 2023 compared to $1.6 billion in 2022. Significant new awards and contract adjustments in 2023 included $788 million of additional funding for certain mass-transit projects in California; a $222 million military facilities project at Tinian International Airport in the Commonwealth of the Northern Mariana Islands; and $127 million of additional funding for a mass-transit project in Minnesota.

New awards in 2022 included $466 million of additional funding for a mass-transit project in California; the $260 million Eagle Mountain - Woodfibre Gas Pipeline project in British Columbia, Canada; $118 million of additional funding for a mass-transit project in the Midwest; and several projects in Guam, including a $107 million military housing project, an $84 million wharf improvement project and two other military facilities projects valued at $73 million and $49 million.

Backlog for the Civil segment was $4.2 billion as of December 31, 2023, down slightly compared to $4.4 billion as of December 31, 2022. 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) from construction operations for the Building segment are summarized as follows:

Revenue for 2023 increased 5% compared to 2022, with the growth driven by increased project execution activities on various projects in California and a detention facility project in New York, all with substantial scope of work remaining, mostly offset by the impact of the aforementioned unfavorable adjustment related to the adverse legal ruling on a completed mixed-use project in New York, and reduced project execution activities on substantially completed projects, including two commercial and industrial facilities in California and two hospitality and gaming projects in Arkansas and California. As discussed above in Executive Overview, revenue for both years was adversely impacted by the follow-on impacts of COVID-19, which delayed certain project bids and awards in 2020 and 2021.

Loss from construction operations for 2023 was $91.2 million compared to income from construction operations of $7.2 million for 2022. For 2023, the loss was primarily due to 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, pre-tax charge of $83.6 million, of which $72.2 million impacted the Building segment and $11.4 million impacted the Specialty Contractors segment, and an unfavorable adjustment of $14.6 million on a government building project in Florida primarily due to increased costs associated with an external subcontractor. The impact of these unfavorable adjustments was partially offset by the absence of a prior-year unfavorable adjustment of $11.3 million related to an adverse legal decision on a hospitality project in Florida. In addition, income (loss) from construction operations for both 2023 and 2022 was similarly unfavorably impacted by adjustments due to changes in estimates on the Building segment’s portion of the aforementioned completed transportation project in the Northeast primarily due to the settlement of certain change orders, changes in estimates due to recent negotiations and incremental cost incurred during project closeout ($14.2 million in 2023 and $15.7 million in 2022).

Operating margin was (7.0)% in 2023 compared to 0.6% in 2022. The decrease in operating margin was driven by the factors mentioned above that drove the lower revenue and income (loss) from construction operations.

New awards in the Building segment totaled $3.3 billion in 2023 compared to $1.2 billion in 2022. Significant new awards and contract adjustments in 2023 included the $2.95 billion Brooklyn Jail project in New York (which includes more than $630 million of electrical and mechanical subcontract work to be performed by the Specialty Contractors segment) and $287 million of additional funding for two large health care projects in California.

Table of Contents

The proliferation of remote and hybrid work for many businesses that began during COVID-19, as well as weaker current 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 commercial 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.

New awards in 2022 included $211 million of additional funding for two educational facility projects in California; a $126 million military facility project in Puerto Rico; a $95 million educational facility project in California; an $85 million military housing project in Alaska; and a $78 million health care project in California.

Backlog for the Building segment was $4.2 billion as of December 31, 2023, up 88% compared to $2.2 billion as of December 31, 2022, with the increase largely driven by the award of the Brooklyn Jail project mentioned above. 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:

Revenue for 2023 decreased 15% compared to 2022, principally due to reduced project execution activities on the electrical and mechanical components of a completed transportation project in the Northeast, as well as the aforementioned unfavorable non-cash adjustments due to changes in estimates on the electrical and mechanical scope of this same project associated with changes in the expected recovery on certain unapproved change orders resulting from ongoing negotiations and the adverse legal ruling on an educational facilities project in New York. The overall revenue decline was partially offset by the absence of prior-year unfavorable adjustments on the same transportation project in the Northeast, a prior-year unfavorable adjustment related to an adverse appellate court decision involving the electrical component of a completed mass-transit project in New York, as well as unfavorable adjustments on two separate mechanical projects in New York, discussed below. As discussed above in Executive Overview, operating results continue to be adversely impacted by the follow-on impacts of COVID-19, which delayed certain project bids and awards in 2020 and 2021, including projects that would have had considerable components of electrical and mechanical scope in the 2022 and 2023 periods had the projects been awarded and the Company won its share of such projects.

Loss from construction operations for 2023 was $144.8 million compared to $168.0 million for 2022, a decrease of $23.2 million. The reduced loss from construction operations was primarily due to the absence of certain prior-year unfavorable adjustments, mostly offset by unfavorable adjustments in 2023. The unfavorable prior-year adjustments included a $46.2 million unfavorable adjustment on the aforementioned transportation project in the Northeast related to the unforeseen cost of project close-out issues, remediation work, extended project supervision and associated labor inefficiencies; the $43.2 million non-cash impact from an unfavorable adjustment related to an adverse appellate court decision involving the electrical component of a completed mass-transit project in New York; a non-cash charge of $17.8 million that increased cost of operations associated with the partial reversal by an appellate court of previously awarded legal damages related to a completed electrical project in New York; the $11.3 million non-cash impact related to settlement negotiations on a mechanical project in New York; and the $11.1 million unfavorable non-cash adjustment related to another mechanical project in New York. The impact from the absence of these prior-year adjustments was mostly offset by unfavorable adjustments in 2023 including $62.2 million of unfavorable non-cash adjustments due to changes in estimates on the electrical and mechanical scope of the above-mentioned completed transportation project in the Northeast associated with changes in the expected recovery on certain unapproved change orders resulting from ongoing negotiations; a non-cash charge of $24.7 million on the educational facilities project in New York that resulted from an adverse court ruling; an unfavorable adjustment of $16.9 million on a multi-unit residential project in New York due to changes in estimates resulting from incremental costs to complete the project and ongoing negotiations on unapproved change orders; and a $9.4 million unfavorable adjustment due to a settlement on a completed mass-transit project in California.

Operating margin was (20.9)% in 2023 compared to (20.7)% in 2022. The change in operating margin was mainly attributable to the aforementioned factors that drove the lower loss from construction operations in 2023.

Table of Contents

New awards in the Specialty Contractors segment totaled $1.1 billion in 2023 compared to $729.3 million in 2022. The most significant new awards in 2023 included more than $630 million of electrical and mechanical subcontract work to be performed on the Brooklyn Jail project in New York; a $67 million communications systems integration project in New York; and the Central District Wastewater Treatment Plant electrical project in Florida, valued at more than $40 million.

Backlog for the Specialty Contractors segment was $1.7 billion as of December 31, 2023, up 35% compared to $1.3 billion as of December 31, 2022, with the increase largely driven by the significant amount of subcontract work booked as part of the Brooklyn Jail project mentioned above. 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 $75.2 million in 2023 compared to $62.2 million in 2022. The increase in corporate general and administrative expenses in 2023 compared to 2022 was primarily due to higher compensation-related expenses including certain employee separation costs and higher salaries associated with additional headcount primarily due to transfers of employees to the corporate group, as well as increased outside professional fees.

Other Income, Net, Interest Expense and Income Tax Benefit

Other income, net increased by $10.5 million in 2023 compared to 2022 primarily due to a gain on sale of property in 2023.

Interest expense increased $15.6 million in 2023 compared to 2022. The increase in 2023 compared to 2022 was substantially due to higher interest rates on the Term Loan B and the Revolver, as discussed below in Liquidity and Capital Resources.

The effective income tax rate was 30.1% for 2023 compared to 28.1% for 2022. The items that caused a higher effective tax rate in 2023 as compared to 2022 were primarily higher earnings attributable to noncontrolling interests (for which income taxes are not the responsibility of the Company), partially offset by lower state income taxes (net of the federal tax benefit). For a further discussion of income taxes, refer to Note 5 of the Notes to Consolidated Financial Statements.

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 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 of $175 million and available cash balances as of December 31, 2023, 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 a record operating cash flow in 2023 which was greater than the previous record set in 2022, as discussed below in Cash and Working Capital. We expect strong operating cash flow to continue in 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. We expect to benefit from the utilization of net operating loss carryforwards to reduce our cash outflows for income taxes.

Cash and Working Capital

Cash and cash equivalents were $380.6 million as of December 31, 2023 compared to $259.4 million as of December 31, 2022. Cash immediately available for general corporate purposes was $145.1 million and $47.7 million as of December 31, 2023 and 2022, 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

27

Table of Contents

$144.4 million as of December 31, 2023 compared to $106.0 million as of December 31, 2022. Restricted cash and restricted investments at December 31, 2023 were primarily held to secure insurance-related contingent obligations and deposits.

During the year ended December 31, 2023, net cash provided by operating activities was $308.5 million, compared to $207.0 million in 2022, representing an increase of $101.5 million. The operating cash flow for 2023 was the largest result for any year since the merger between Tutor-Saliba Corporation and Perini Corporation in 2008, exceeding the previous record achieved in 2022. The record operating cash flow in 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 improved collection activity, as reflected by a decrease in costs and estimated earnings in excess of billings and accounts receivable, and an increase in billings in excess of costs and estimated earnings (“BIE”). During the year ended December 31, 2022, net cash provided by operating activities was $207.0 million 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 improved collection activity, as reflected by a decrease in accounts receivable and an increase in BIE.

As noted above, cash flow from operating activities increased $101.5 million when comparing 2023 with 2022. The increase was primarily driven by higher collections in 2023 compared to 2022, as well as a larger decrease in investments in working capital in 2023 compared to the prior year. Both periods generated significant cash from decreased investments in working capital as collection activities were strong in both 2023 and 2022, which included the positive impacts of collections associated with previously disputed matters.

During 2023, net cash used in investing activities was $78.2 million, which was primarily due to the acquisition of property and equipment (i.e., capital expenditures), which totaled $53.0 million, as well as net cash used in investment transactions of $35.4 million, partially offset by proceeds from the sale of property and equipment of $10.1 million. During 2022, net cash used in investing activities was $65.6 million, which was primarily due to the acquisition of property and equipment of $59.8 million, as well as net cash used in investment transactions of $14.5 million, partially offset by proceeds from the sale of property and equipment of $8.6 million.

During 2023, net cash used in financing activities was $109.4 million, which was primarily driven by net repayment of borrowings of $61.7 million and $46.5 million of cash distributions to noncontrolling interests, partially offset by $2.0 million of cash contributions from noncontrolling interests. During 2022, net cash used in financing activities was $78.9 million, which was primarily driven by net repayment of borrowings of $38.3 million and $47.4 million of cash distributions to noncontrolling interests, partially offset by $8.7 million of cash contributions from noncontrolling interests.

As of December 31, 2023, we had 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 compared to working capital of $1.7 billion, a ratio of current assets to current liabilities of 1.87 and a ratio of debt to equity of 0.66 at December 31, 2022.

Debt

Summarized below are the key terms of our debt as of December 31, 2023. For additional information, refer to Note 7 of the Notes to Consolidated Financial Statements, as applicable.

2020 Credit Agreement

On August 18, 2020, the Company entered into a credit agreement (the “2020 Credit Agreement”) with 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”), 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 (which is 5.95:1.00 for the year ended December 31, 2023), 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”). As amended on December 20, 2023, 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. 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.

The Company is working to refinance the 2017 Senior Notes and anticipates that it will complete a refinancing transaction by the end of April 2024. The Company expects the terms of any refinanced debt to include interest rates that are higher than those of its current issuances under the 2017 Senior Notes. The Company’s strong operating cash flow in 2023 and continuing robust cash collections in early 2024 have enabled it to begin utilizing some of its accumulated cash for debt reduction, as discussed below.

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 and 2022, current maturities of long-term debt in the accompanying Consolidated Balance Sheets included $91.0 million and $44.0 million, respectively, 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, and the $44.0 million principal prepayment was made in April 2023. After the February 2024 prepayment, the Company still has significant cash available, which is anticipated to be used for further debt reduction in conjunction with the expected refinancing.

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 year ended December 31, 2023 were approximately 10.1% and 11.8%, respectively. At December 31, 2023, 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 7 of the Notes to 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:

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 December 31, 2023, we were in compliance and expect to continue to be in compliance with the covenants under the 2020 Credit Agreement.

2017 Senior Notes

On April 20, 2017, the Company issued $500 million in aggregate principal amount of 6.875% Senior Notes due May 1, 2025 (the “2017 Senior Notes”) in a private placement offering. Interest on the 2017 Senior Notes is payable in arrears semi-annually in May and November of each year, beginning in November 2017.

Equipment Financing and Mortgages

The Company has certain loans entered into for the purchase of specific property, plant and equipment and secured by the assets purchased. The aggregate balance of equipment financing loans was approximately $26.4 million and $37.0 million at December 31, 2023 and 2022, respectively, with interest rates ranging from 2.54% to 7.32% with equal monthly installment payments over periods up to 5 years. The aggregate balance of mortgage loans was approximately $8.4 million and $11.6 million at December 31, 2023 and 2022, respectively, with interest rates ranging from a fixed 2.25% to SOFR plus 2.00% and monthly installment payments over periods up to 10 years.

Contractual Obligations

Our contractual obligations and commitments as of December 31, 2023 include:

•Debt obligations of $910.7 million (of which $117.4 million are due in 2024) and interest payments of $151.3 million (of which $66.4 million are due in 2024) based on rates in effect as of December 31, 2023. See Note 7 of the Notes to Consolidated Financial Statements for further detail of our debt and the timing of expected future principal and interest payments.

•Operating lease obligations of $97.2 million (of which $12.0 million are due in 2024). See Note 9 of the Notes to Consolidated Financial Statements for further detail of our lease obligations and the timing of expected future payments.

Critical Accounting Estimates

Our discussion and analysis of our financial condition and results of operations is based upon our Consolidated Financial Statements, which have been prepared in accordance with GAAP. Our significant accounting policies are described in Note 1 of the Notes to Consolidated Financial Statements. The preparation of the Consolidated Financial Statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. Estimates are based on information available through the date of the issuance of the financial statements; accordingly, actual results in future periods could differ from these estimates. Significant judgments and estimates used in the preparation of the Consolidated Financial Statements apply to the following critical accounting policies:

Method of Accounting for Contracts — Contract revenue is recognized over time using the cost-to-cost method which measures progress towards completion based on the ratio of contract costs incurred to date compared to total estimated costs for each performance obligation. The estimates used in accounting for contracts with customers require judgment and assumptions regarding both future events and the evaluation of contingencies such as the impact of change orders, liability claims, other contract disputes, the achievement of contractual performance standards and potential variances in project schedule and costs. Changes to the total estimated contract cost, either due to unexpected events or revisions to management’s initial estimates, for a given project are recognized in the period in which they are determined.

In certain instances, we provide guaranteed completion dates and/or achievement of other performance criteria. Failure to meet schedule or performance guarantees could result in unrealized incentive fees and/or liquidated damages. In addition, depending on the type of contract, unexpected increases in contract cost may be unrecoverable, resulting in total cost exceeding revenue realized from the projects. The Company generally provides limited warranties for work performed, with warranty periods typically extending for a limited duration following substantial completion of the Company’s work on a project. Historically, warranty claims have not resulted in material costs incurred.

Claims arising from construction contracts have been made against the Company by customers, and the Company has made claims against customers for costs incurred in excess of current contract provisions. The Company recognizes revenue for claims as variable consideration in accordance with Accounting Standards Codification (“ASC”) 606, Revenue from Contracts

30

Table of Contents

with Customers (“ASC 606”). Assumptions as to the occurrence of future events and the likelihood and amount of variable consideration are made during the contract performance period. Estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of anticipated performance and all information (historical, current and forecasted) that is reasonably available to management. Estimated amounts are only included in the transaction price 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. Back charges to suppliers or subcontractors are recognized as a reduction of cost when it is determined that recovery of such cost is probable and the amounts can be reliably estimated. Disputed back charges are recognized when the same requirements described above for variable consideration have been satisfied.

See Executive Overview and Results of Segment Operations sections for further discussion and quantification of material charges related to changes in estimates resulting from legal judgments or decisions, settlements and other project charges.

Construction Joint Ventures — Certain contracts are executed through joint ventures. The arrangements are often formed for the execution of single contracts or projects and allow the Company to share risks and secure specialty skills required for project execution.

In accordance with ASC 810, Consolidation (“ASC 810”) the Company assesses its joint ventures at inception to determine if any meet the qualifications of a variable interest entity (“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 the joint venture is a VIE.

The Company also evaluates whether it is the primary beneficiary of each VIE and consolidates the VIE if the Company has both (a) the power to direct the economically significant activities of the entity and (b) the obligation to absorb losses of, or the right to receive benefits from, the entity 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 whether it qualifies as the primary beneficiary. The Company also considers all parties that have direct or implicit variable interests when determining whether it is the primary beneficiary. When the Company is determined to be the primary beneficiary, the VIE is consolidated. In accordance with ASC 810, management’s assessment of whether the Company is the primary beneficiary of a VIE is performed continuously.

For construction joint ventures that do not need to be fully consolidated but qualify for the equity method of accounting, the Company accounts for its interest in the joint ventures using the proportionate consolidation method, whereby the Company’s proportionate share of the joint ventures’ assets, liabilities, revenue and cost of operations are included in the appropriate classifications in the Company’s consolidated financial statements. Intercompany balances and transactions are eliminated. See Note 1(b) and Note 13 of the Notes to Consolidated Financial Statements for additional discussion regarding VIEs.

Recoverability of Goodwill — Goodwill represents the excess of amounts paid over the fair value of net assets acquired from an acquisition. In order to determine the amount of goodwill resulting from an acquisition, we perform an assessment to determine the value of the acquired company's tangible and identifiable intangible assets and liabilities. In our assessment, we determine whether identifiable intangible assets exist, which typically include backlog, customer relationships and trade names.

We test goodwill for impairment annually as of October 1 of each year. This test requires us to estimate the fair value of each reporting unit carrying goodwill using income and market approaches, and to compare the calculated fair value of each reporting unit to its carrying value, which is equal to the reporting unit’s net assets. If the calculated fair value of a reporting unit is less than its carrying value, we recognize an impairment charge equal to the difference.

The impairment evaluation process requires assumptions that are subject to a high degree of judgment such as revenue growth rates, profitability levels, discount rates, industry market multiples and weighted-average cost of capital. Changes in these assumptions would impact the results of our impairment tests.

During interim periods, including those subsequent to the Company’s October 1 annual test date, we evaluate events and circumstances, including, but not limited to, an examination of macroeconomic conditions, cost factors, overall financial performance by each reporting unit, other relevant entity-specific events, and trends in the stock prices of our Company and

31

Table of Contents

peers to determine if such factors indicate that it is likely that the goodwill for one or more of our reporting units is impaired, thus warranting the performance of a quantitative impairment test sooner than the fourth quarter of the year.

During the fourth quarter of 2023, we conducted our annual goodwill impairment test and determined that goodwill was not impaired since the estimated fair value of the Civil reporting unit exceeded its net book value by a significant amount. However, there is a risk of goodwill impairment if future events are less favorable than what we assumed or estimated in our impairment analysis.

The Company has considered relevant events and circumstances since the annual goodwill impairment test, including, but not limited to, an examination of macroeconomic conditions, industry and market conditions, cost factors, overall financial performance by each reporting unit, other relevant entity-specific events, and trends in the stock prices of the Company and its peers. In considering the totality of qualitative factors known as of the reporting date, we determined that no triggering events occurred or circumstances changed since our October 1, 2023 annual test that would more likely than not reduce the fair value of the Civil reporting unit below its carrying amount. We will continue to monitor events occurring or circumstances changing which may suggest that goodwill should be reevaluated. These events and circumstances include, but are not limited to, changes in the overall financial performance of the Civil reporting unit and other quantitative and qualitative factors specific to the Civil reporting unit which indicate potential triggering events that would more likely than not reduce the fair value of the Civil reporting unit below its carrying amount.

Executive Overview

COVID-19 Update

From its onset at the beginning of 2020 through the early months of 2022, the COVID-19 pandemic caused occasional temporary shortages in available manpower, reductions in field labor productivity, other inefficiencies, delays to project schedules and deferrals of project execution. As a result, during that period we incurred incremental costs, much of which we have sought to recover from our customers as allowed by contractual terms. The relief sought from customers, together with certain incremental project opportunities that resulted from the pandemic, helped to mitigate the pandemic's negative impact on our financial results over that period. We also experienced significant delays in certain legal proceedings from the onset of the pandemic through the latter part of 2021, during which time the operations of various courts and arbitrations were shut down or

Table of Contents

reduced, and after which they faced processing a backlog of delayed cases. The COVID-19 pandemic also previously hindered the Company’s ability to resolve disputes related to unapproved work, which resulted in the need for the Company to temporarily fund certain project costs that historically would have been promptly negotiated, billed to and collected from customers. These delays in resolving and recovering on such claims adversely affected our liquidity and financial results from the onset of the pandemic through the end of 2021. These various negative impacts from the pandemic lessened in 2022, with certain previously delayed disputes finally resolved and other settlement conferences and trial dates now scheduled or being scheduled. The Company expects to make substantial continued progress in the resolution of certain other disputes and unapproved change orders in 2023 and beyond.

Through the latter part of 2021, the pandemic also significantly delayed the bidding and awarding of various large prospective civil projects, which affected the volume and timing of our new awards. The follow-on impact has been a substantial reduction in our backlog, revenue and income from construction operations over the past three years. For example, the Company’s consolidated backlog had been near a record level at $11.2 billion as of December 31, 2019, just prior to the onset of the COVID-19 pandemic, but has declined in each subsequent year and was $7.9 billion as of December 31, 2022, a 29% decrease compared to the end of 2019. Similarly, revenue declined 29% from $5.3 billion for 2020 to $3.8 billion for 2022, though there are other factors which contributed to the revenue decline, as discussed below. While the current impacts from the pandemic have lessened in 2022, the follow-on impact continues to limit our backlog and operating results. In addition, many of our state and local government customers’ revenue sources were negatively impacted by the pandemic due to a reduction of commuter and business travel. In many places, commuter travel, particularly on mass-transit systems, has yet to return to pre-pandemic levels and may not reach those levels for several more years, which may continue to constrain revenue sources for certain customers. The significant revenue reductions experienced by some of our customers have adversely impacted their ability to pay the Company on a timely basis for amounts due, although these impacts have continued to moderate.

Operating Results

Consolidated revenue for 2022 was $3.8 billion compared to $4.6 billion for 2021. The decrease was primarily due to reduced project execution activities on various projects in all three segments, most of which are completed or nearing completion, partially offset by increased activities on certain newer Civil and Building segment projects in California and the Midwest. As certain large existing projects have completed or are nearing completion, several factors have contributed to delays or have prevented significant revenue contributions from new and prospective projects. The primary factor was the COVID-19 pandemic, which delayed bidding activities and awards of certain new projects during 2020 and much of 2021 and induced customer budgetary constraints. The impact of the pandemic combined with certain political and other factors resulted in the Company not being awarded certain Civil segment projects totaling more than $10.0 billion despite having been the low or preferred bidder. Most of these projects impacted revenue in 2022 and are expected to be re-bid in 2023 or 2024. In addition, the Company was unsuccessful in its pursuit of certain large prospective Civil segment projects in the second half of 2021. The decrease for 2022 was also due to the net unfavorable impact of various project adjustments in 2022 that resulted from certain adverse legal judgments, significant settlement activity, project charges due to changes in estimates, and increases in unapproved work that reduced the percentage of completion and profit margin on certain projects. These effects were partially offset by the positive impacts from the release of cost contingencies on certain projects.

Loss from construction operations for 2022 was $204.8 million compared to income from construction operations of $226.8 million for 2021. The decrease was primarily due to the following net impacts in 2022 that also reduced revenue: 1) certain adverse legal judgments or decisions of $147.8 million in the aggregate; 2) various settlements that had a net negative impact of $85.4 million in the aggregate; and 3) various changes in estimates for project charges, net of positive impacts from improved productivity and efficiencies on certain projects, which had an aggregate net negative impact of $96.8 million. In addition, there was $119.7 million of temporary aggregate negative project adjustments in 2022 due to increases in unapproved work on various projects, as well as the successful negotiation of significant lower margin (and lower risk) change orders on a Civil segment mass-transit project in California, all of which are expected to reverse themselves over the remaining lives of the projects. The reduced revenue volume discussed above also contributed to a $58.2 million decline in income (loss) from construction operations in 2022 as compared to 2021. The material project adjustments associated with these factors are discussed below.

Adverse legal judgments or decisions during 2022 included a $43.2 million non-cash impact related to the electrical component of a completed mass-transit project in New York in the Specialty Contractors segment, a $26.2 million unfavorable non-cash impact due to the reversal on appeal of a previously favorable lower-court ruling related to a completed Civil segment highway project in the Northeast, a $25.5 million non-cash impact related to a completed Civil segment bridge project in New York, a $17.8 million non-cash impact associated with the partial reversal by an appellate court of previously awarded legal damages related to a completed electrical project in New York in the Specialty Contractors segment, an $11.3 million impact related to a Building segment hospitality project in Florida and a $10.0 million non-cash impact related to a Civil segment mass-transit project in New York.

Table of Contents

Settlements during 2022 had an aggregate net negative impact of $85.4 million, as referred to above, which included unfavorable impacts related to certain Specialty Contractors segment projects in New York that collectively totaled $32.9 million, one of which negatively impacted profitability by $11.3 million, with the remainder of the negative impacts in the Specialty Contractors segment comprised of unfavorable settlements that were individually immaterial. Other settlements in 2022 included a $16.2 million unfavorable non-cash impact related to a long-disputed, completed Civil segment project in Maryland, a $13.4 million unfavorable non-cash impact (split evenly between the Civil and Building segments) related to a transportation project in the Northeast, an $11.6 million unfavorable non-cash impact related to a Civil segment mass-transit project in California, as well as the unfavorable impact of various other settlements that were individually immaterial, partially offset by a $12.7 million favorable impact related to a Civil segment bridge project in the Midwest.

In 2022, the Company began to implement changes to its business strategy, primarily with respect to collections and operations in its Specialty Contractors segment in New York. Specifically, in the latter part of 2022, management increasingly focused on expeditiously negotiating settlements of certain Specialty Contractors segment disputes in New York to accelerate the collection of cash and reduce the risk and uncertainty associated with continued lengthy and costly litigation, arbitration proceedings and settlement negotiations. This new strategic approach to collections also took account of certain unfavorable legal judgments and decisions in recent years, particularly in New York, and the possibility that future litigation and arbitration in New York could have a similar outcome. The new approach is also intended to reduce the Company’s legal expenses and allow management to focus more on the successful execution of projects and on growing the business. In implementing this change in collections strategy, management concluded that significant concessions would be required in a number of disputes to facilitate settlements. Ultimately, the Company agreed to settle these disputes for amounts less than what had previously been estimated and might have been obtained if the disputes had been litigated to conclusion. This shift in collections strategy contributed to the significant decline in income from construction operations in 2022 and most of the resulting cash is expected to be collected in 2023.

Also as part of the Company’s change in business strategy, the Company made certain key leadership changes that it expects will have a positive impact on the Specialty Contractors segment’s future operations. First, management replaced key members of the leadership team at WDF, the Company’s New York mechanical business unit, with experienced Company veterans. In the latter part of 2022, the Company also appointed one of its seasoned senior executives with previous experience in dealing with New York public agencies and customers to a new role overseeing the Specialty Contractors and Building segments, and expects that he will successfully lead efforts to drive growth, increased profitability and operational improvements, particularly in the Specialty Contractors segment. The Company also increasingly became more selective in the types of projects that it will pursue and execute in New York, particularly in its Specialty Contractors operations, and it has implemented certain risk diversification measures aimed at better managing larger components of electrical work expected to be performed. Finally, because of more limited competition and high customer demand for large, complex Civil and Building segment projects, since the latter part of 2021, the Company has been successfully negotiating improved project contractual terms, which the Company believes will contribute to a more equitable allocation of risk by making certain delays and events compensable, as well as promoting better working capital efficiency in all three segments.

As noted above, other significant project charges due to changes in estimates in 2022 had a net negative impact of $96.8 million. These included a $36.1 million charge due to unfavorable adjustments related to the unforeseen cost of project close-out issues, remediation work, extended project supervision and associated labor inefficiencies on the electrical (Specialty Contractors segment) component of a transportation project in the Northeast; an $18.0 million charge related to similar project close-out issues (split evenly between the Civil and Building segments) on the same transportation project in the Northeast; a $13.1 million charge due to inefficiencies and cost overruns on a Civil segment mass-transit project in California; and $11.1 million of charges related to close-out discussions for a mechanical project in New York in the Specialty Contractors segment, as well as the net unfavorable impact of changes in estimates on numerous other projects that were individually immaterial. All of the project charges were due to changes in facts and circumstances that were identified in 2022. In certain cases, the changes in facts and circumstances resulted in changes in estimates to the expected recoveries for certain disputed matters, which were identified as part of the implementation of the new collections strategy and were primarily related to the Specialty Contractors segment in New York.

The 2022 temporary aggregate negative project adjustments of $119.7 million referred to above included a temporary unfavorable non-cash impact of $38.8 million resulting from the successful negotiation of significant lower margin (and lower risk) change orders on a Civil segment mass-transit project in California. These approved change orders increased the project’s overall estimated profit but reduced the project’s percentage of completion and overall margin percentage. As indicated above, this temporary reduction to earnings is expected to reverse itself over the remaining life of the project. The remaining amount of temporary negative project adjustments was due to growth in unapproved change orders on various projects that reduced the projects’ percentage of completion and profit margin, which are also expected to reverse over the remaining lives of the projects. The largest portion of this remaining amount was a $10.1 million temporary unfavorable impact on the electrical (Specialty Contractors segment) component of a transportation project in the Northeast.

Other prior-year factors also contributed to the change in income (loss) from construction operations in 2022 as compared to 2021, including the absence in 2022 of a $29.0 million favorable adjustment in 2021 on a Civil segment mass-transit project in California, the absence in 2022 of a $20.1 million favorable adjustment in 2021 related to the same completed electrical project in New York in the Specialty Contractors segment that resulted in a $17.8 million non-cash charge in 2022 associated with the partial reversal by an appellate court of previously awarded legal damages and the absence in 2022 of $16.3 million of favorable adjustments in 2021 on a Civil segment mass-transit project. These favorable adjustments in 2021 were partially offset by the impact in 2021 of unfavorable adjustments on the aforementioned transportation project in the Northeast totaling $63.2 million ($19.0 million and $17.6 million on the project’s mechanical and electrical components, respectively, impacting the Specialty Contractors segment, and $26.6 million split evenly between the Civil and Building segments), and $16.2 million from changes in estimates on an electrical mass-transit project in New York in the Specialty Contractors segment.

The effective income tax rate for 2022 was 28.1% compared to 16.0% for 2021. See Corporate, Tax and Other Matters below for a discussion of the changes in the effective tax rate.

Diluted loss per common share for 2022 was $4.09 compared to diluted earnings per common share of $1.79 for 2021. The decrease in 2022 was principally due to the factors discussed above that drove the decrease in income (loss) from construction operations.

Consolidated new awards in 2022 were $3.5 billion compared to $4.5 billion in 2021. The Civil and Building segments were the primary contributors to the new award activity in 2022. Significant new awards in 2022 included $466 million of additional funding for a mass-transit project in California; the $260 million Eagle Mountain - Woodfibre Gas Pipeline project in British Columbia, Canada; $211 million of additional funding for two educational facility projects in California; $126 million for a military facilities project in Puerto Rico; $118 million of additional funding for a mass-transit project in the Midwest; and a $107 million military housing project in Guam.

Consolidated backlog as of December 31, 2022 was $7.9 billion, down modestly compared to $8.2 billion as of December 31, 2021. Backlog for both 2021 and 2022 was negatively impacted by several factors discussed above, including the COVID-19 pandemic due to reduced bidding and proposal activity. As of December 31, 2022, the mix of backlog by segment was 56% for Civil, 28% for Building and 16% for Specialty Contractors, compared to 55% for Civil, 28% for Building and 17% for Specialty Contractors at the end of 2021.

The Company had certain large Civil segment projects in the Northeast that were completed or were nearing completion in 2022. The Company has several pending significant new projects with contract awards expected in 2023 totaling a combined value that could exceed $3 billion. However, the timing and magnitude of revenue contributions from these prospective projects may not fully offset revenue reductions associated with the projects that have been completed or are nearing completion. In addition, the COVID-19 pandemic resulted in significant revenue shortfalls for certain state and local government agencies since 2020, and it could continue to cause deferrals or cancellations of certain new projects, depending on the allocation and prioritization of state and local funding, as well as the availability, timing and magnitude of funding from the federal government, including anticipated funding from the BIL.

Most projects in the Civil segment’s backlog typically convert to revenue over a period of three to five years and in the Building and Specialty Contractors segments over a period of one to three years. We estimate that approximately $4 billion, or 45%, of our backlog as of December 31, 2022 will be recognized as revenue in 2023.

The following table presents the changes in backlog in 2022:

_____________________________________________________________________________________________________________

(a)New awards consist of the original contract price of projects added to our 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 Consolidated Financial Statements. Such differences relate to the timing of executing a formal contract or receiving a notice to proceed. More specifically, backlog sometimes 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 growth over the next several years remains favorable, but it could be negatively impacted by future project delays or the timing of project bids, awards, commencements, ramp-up activities and completions, as well as by any adverse follow-on consequences of the COVID-19 pandemic. We anticipate that we will continue to win our share of significant new awards resulting from long-term 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 in 44 states have approved 85% of nearly 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. In addition, California's Senate Bill 1, which was signed into law in 2017, is providing an average of $5.4 billion annually through 2027 for various transportation, mass-transit and bridge projects. Interest rates have risen over the past year, as anticipated, but are still at levels which we believe remain conducive to continued spending on various types of projects. However, if borrowing rates continue to increase, they could reach levels that may negatively impact demand, particularly for certain Building segment end markets which tend to be more closely correlated to economic conditions.

The BIL was enacted into law on November 15, 2021, and it 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 marks 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, 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 will favorably impact the Company’s current work and prospective opportunities over the next decade, as initial funds have begun flowing to project owners and substantially increased funding from the BIL is expected to occur over the next several years.

For a more detailed discussion of 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:

Revenue for 2022 decreased 17% compared to 2021, primarily due to reduced project execution activities on certain mass-transit, transportation and bridge projects in California, the Northeast and the Midwest, respectively, that are completed or nearing completion, partially offset by increased activities on certain projects in the Midwest and California. Revenue for both 2021 and 2022 was also reduced by a lower level of new awards partly due to the impact of the COVID-19 pandemic, the Company’s lack of success in its pursuit of certain large prospective Civil segment projects in the second half of 2021, certain projects for which the Company was the lowest bidder but no contract was awarded due to customer budget constraints, and revenue reductions associated with the various unfavorable impacts discussed in the paragraph below.

Income from construction operations for 2022 decreased 92% compared to 2021 due to various factors, including the lower profitability associated with the temporary unfavorable impact of $38.8 million resulting from the successful negotiation of significant lower margin (and lower risk) change orders on a mass-transit project in California (where the temporary reduction to earnings is expected to reverse itself over the remaining life of the project), the $26.2 million unfavorable non-cash impact related to a completed highway project in the Northeast due to the reversal on appeal of a previously favorable lower-court

Table of Contents

ruling, the $25.5 million unfavorable non-cash impact related to the adverse legal judgment on a dispute related to a completed bridge project in New York, the $16.2 million unfavorable non-cash impact related to the settlement of a long-disputed, completed project in Maryland, the $13.1 million charge due to inefficiencies and cost overruns and the $11.6 million unfavorable non-cash settlement impact, both related to another mass-transit project in California and the $10.0 million non-cash impact related to an unfavorable adjustment resulting from an adverse legal decision on a mass-transit project in the Northeast. These unfavorable impacts were partially offset by the favorable impact of a project close-out adjustment of $12.7 million on a bridge project in the Midwest. Other factors that contributed to the decrease in income from construction operations included the absence in 2022 of certain favorable adjustments in 2021, including a $29.0 million favorable adjustment on a mass-transit project in California and $16.3 million of favorable adjustments on a mass-transit project in the Midwest. In addition, the income from construction operations for both 2022 and 2021 were similarly unfavorably impacted by adjustments due to changes in estimates on a transportation project in the Northeast ($15.7 million in 2022 and $13.3 million in 2021). Income from construction operations in 2022 was also negatively impacted due to the reduced revenue volume discussed above.

Operating margin was 1.2% for 2022 compared to 12.7% in 2021. The decrease in operating margin for 2022 was primarily due to the factors discussed above that drove the decrease in income from construction operations.

New awards in the Civil segment totaled $1.6 billion in 2022 compared to $1.9 billion in 2021. New awards in 2022 included $466 million of additional funding for a mass-transit project in California; the $260 million Eagle Mountain - Woodfibre Gas Pipeline project in British Columbia, Canada; $118 million of additional funding for a mass-transit project in the Midwest; and several projects in Guam, including a $107 million military housing project, an $84 million wharf improvement project and two other military facilities projects valued at $73 million and $49 million. The COVID-19 pandemic has caused significant revenue shortfalls for certain state and local government agencies since 2020, and it could continue to cause deferrals or cancellations of certain new projects, depending on the allocation and prioritization of state and local funding, as well as the availability, timing and magnitude of funding from the federal government, including anticipated funding from the BIL. The Company is pursuing and expects to win its share of several large Civil segment projects in 2023.

New awards in 2021 included $434 million for various Civil segment projects in the Midwest; more than $385 million of additional funding for certain mass-transit projects in California; the $220 million I-70 Missouri River Bridge project; the $162 million Tinian International Airport aircraft parking apron and taxiway project in the Northern Mariana Islands; and a $122 million military range project and a $98 million military housing project, both in Guam.

Backlog for the Civil segment was $4.4 billion as of December 31, 2022, down slightly compared to $4.6 billion as of December 31, 2021. 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, but the timing of new awards remains uncertain.

Building Segment

Revenue and income from construction operations for the Building segment are summarized as follows:

Revenue for 2022 decreased 13% compared to 2021, primarily due to reduced project execution activities on various projects in California, Oklahoma and the Northeast that are completed or nearing completion, partially offset by contributions from certain newer projects in California. Revenue for both 2021 and 2022 was also reduced by the aforementioned COVID-19 impacts.

Income from construction operations for 2022 decreased 75% compared to 2021, primarily due to reduced project execution activities on a transportation project in the Northeast that is nearing completion and the $11.3 million impact related to an adverse legal decision on a hospitality project in Florida. In addition, the income from construction operations for both 2022 and 2021 were similarly unfavorably impacted by adjustments due to changes in estimates on the same transportation project in the Northeast ($15.7 million in 2022 and $13.3 million in 2021).

Operating margin was 0.6% in 2022 compared to 2.0% in 2021. The decrease in operating margin was driven by the factors mentioned above that drove the lower revenue and income from construction operations.

23

Table of Contents

New awards in the Building segment totaled $1.2 billion in 2022 compared to $2.0 billion in 2021. New awards in 2022 included $211 million of additional funding for two educational facility projects in California; a $126 million military facility project in Puerto Rico; a $95 million educational facility project in California; an $85 million military housing project in Alaska; and a $78 million health care project in California. The lingering effects of the COVID-19 pandemic, including the proliferation of remote and hybrid work, as well as slowing economic conditions caused by higher inflation and rising interest rates, could continue to result in certain delayed or even canceled building project opportunities, particularly in the corporate office end market. However, other building end markets, such as correctional facilities, health care, education, and hospitality and gaming, continue to show strong demand for new and renovated facilities.

New awards in 2021 included the Cedars-Sinai Marina del Rey Hospital in California (contract value undisclosed); the $471 million LAX Airport Metro Connector project; the $269 million Yountville Veterans Home in California; and the $152 million Santa Rosa Courthouse project in California.

Backlog for the Building segment was $2.2 billion as of December 31, 2022, down slightly compared to $2.3 billion as of December 31, 2021. The Building segment continues to have a large volume of prospective projects across various end markets and geographic locations. However, as discussed above, there could continue to be reduced demand for our services in certain building end markets.

Specialty Contractors Segment

Revenue and loss from construction operations for the Specialty Contractors segment are summarized as follows:

Revenue for 2022 decreased 27% compared to 2021, primarily due to reduced project execution activities on the electrical and mechanical components of a transportation project in the Northeast that is nearing completion, reduced project execution activities on various other electrical and mechanical projects in the Northeast and California that are completed or nearing completion, as well as revenue reductions associated with the various unfavorable impacts discussed in the paragraph below. Revenue for both 2021 and 2022 was also reduced by the aforementioned COVID-19 impacts.

Loss from construction operations for 2022 was $168.0 million compared to $10.0 million for 2021. The change in loss from construction operations was due to various factors discussed above in the section titled Operating Results, including the $43.2 million non-cash impact from an unfavorable adjustment related to an adverse appellate court decision involving the electrical component of a completed mass-transit project in New York, the $17.8 million unfavorable impact associated with the partial reversal by an appellate court of previously awarded legal damages related to a completed electrical project in New York, the $11.3 million non-cash impact related to settlement negotiations on a mechanical project in New York and the $11.1 million charge related to another mechanical project in New York. The volume reduction mentioned above also contributed to the increase in loss from construction operations, as did the absence of a $20.1 million prior-year favorable adjustment that resulted from damages awarded by the trial court’s ruling on the same completed electrical project in New York that resulted in a $17.8 million non-cash charge (due to a partial appellate court reversal) in 2022, partially offset by the unfavorable prior-year impact of $16.2 million from changes in estimates on an electrical mass-transit project in New York. The loss from construction operations for both 2022 and 2021 were similarly unfavorably impacted by adjustments including $36.1 million in 2022 related to the unforeseen cost of project close-out issues, remediation work, extended project supervision and associated labor inefficiencies on the electrical component of a transportation project in the Northeast, the $10.1 million impact in 2022 on this same project due to growth in unapproved change orders that reduced the project’s percentage of completion and profit margin, and unfavorable adjustments in 2021 of $19.0 million and $17.6 million on the mechanical and electrical components of the same project, respectively, due to changes in estimates that included charges and/or the negative impact to earnings from growth in unapproved change orders.

Operating margin was (20.7)% in 2022 compared to (0.9)% in 2021. The decrease in operating margin was mainly attributable to the aforementioned factors that drove the larger loss from construction operations in 2022.

New awards in the Specialty Contractors segment totaled $729 million in 2022 compared to $631 million in 2021. The increase in new awards in 2022 was due in part to fewer lingering impacts from the COVID-19 pandemic as compared to the prior year, as project bidding and awarding activities resumed. However, the COVID-19 pandemic has resulted in, and could continue to result in, reduced demand from certain customers, particularly in New York, that continue to experiencing funding constraints.

24

Table of Contents

New awards in 2021 were mostly comprised of $370 million for various electrical and mechanical projects in the Northeast, and $260 million for various electrical and mechanical projects in Florida, Texas and California.

Backlog for the Specialty Contractors segment was $1.3 billion as of December 31, 2022, down modestly compared to $1.4 billion as of December 31, 2021. The Specialty Contractors segment continues to be increasingly focused on servicing the Company’s current and prospective large Civil and Building segment projects, particularly in the Northeast and California. In addition, 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 $62.2 million in 2022 compared to $58.0 million in 2021. The increase in corporate general and administrative expenses in 2022 compared to 2021 was predominantly due to higher compensation-related expenses.

Other Income, Net, Interest Expense and Income Tax (Expense) Benefit

Other income, net increased by $4.7 million in 2022 compared to 2021 primarily due to interest earned on federal income tax receivable balances.

Interest expense increased $0.6 million in 2022 compared to 2021. Cash interest expense increased $2.7 million in 2022 compared to 2021 primarily due to interest rate increases, partially offset by $2.1 million in lower amortization of debt discounts and debt issuance costs, as well as lower average outstanding debt balances.

The effective income tax rate was 28.1% for 2022 compared to 16.0% for 2021. In periods reporting pre-tax losses, tax benefits generated during the period increase the effective income tax rate (and, thus, the income tax benefit to the Company). The tax benefits in 2022 that increased the tax rate compared to 2021 were primarily earnings attributable to noncontrolling interests (for which income taxes are not the responsibility of the Company) and state income taxes (net of federal benefits). In addition, the 2021 effective income tax rate reflects an $8.2 million benefit related to a federal claim of right tax credit, which contributed to the lower effective income tax rate. For a further discussion of income taxes, refer to Note 5 of the Notes to Consolidated Financial Statements.

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 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 of $175 million and available cash balances as of December 31, 2022, will be sufficient to fund any working capital needs and debt maturities for the next 12 months and beyond, including the expected prepayment of $44.0 million on the Term Loan B in the second quarter of 2023 due to a prepayment requirement in the Credit Agreement as a result of the Company generating “excess” cash flow in 2022, as discussed below in Debt. Despite our record operating cash flow for the year ended December 31, 2022 (as discussed below in Cash and Working Capital), liquidity has been and could continue to be constrained by the follow-on impacts of the COVID-19 pandemic, which delayed bidding activities and awards of certain large civil projects, as well as the associated cash collection opportunities. We are also still pursuing COVID-19-related cost recoveries from certain customers. Our liquidity was also adversely impacted by the Company’s lack of success in its pursuit of certain large prospective Civil segment projects in the second half of 2021, as well as by instances where the Company was the lowest bidder but no contract was awarded due to customer budget constraints. In addition, as discussed above in Executive Overview - COVID-19 Update, the COVID-19 pandemic delayed court and arbitration schedules and also hindered the Company’s ability to resolve certain unapproved work. We believe that future funding from the BIL and increasing revenue to government customers as travel and commuting levels rise, as discussed above, could offset or mitigate these and other possible lingering future negative impacts from the COVID-19 pandemic, though it remains difficult to predict any of these factors. Furthermore,

25

Table of Contents

the backlog of accumulated court and arbitration proceedings that grew as a result of the pandemic during 2020 and 2021 has begun to recede, with certain disputes having been resolved in 2022 and other settlement conferences and trial dates now scheduled or being scheduled. In addition, certain disputes and related collection delays were resolved during the latter part of 2021, as well as during 2022. We experienced substantially improved operating cash flows in 2022 compared to 2021 and expect strong operating cash flows to continue into 2023, based on projected cash collections, both from project execution activities and the resolution of additional outstanding claims and unapproved change orders. The Company expects that its recent strategic decision to emphasize accelerating settlements and collections, primarily in the Specialty Contractors segment in New York, as discussed above, will contribute to operating cash generation in 2023.

Cash and Working Capital

Cash and cash equivalents were $259.4 million as of December 31, 2022 compared to $202.2 million as of December 31, 2021. Cash immediately available for general corporate purposes was $47.7 million and $60.2 million as of December 31, 2022 and 2021, 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 $106.0 million as of December 31, 2022 compared to $93.6 million as of December 31, 2021. Restricted cash and restricted investments at December 31, 2022 were primarily held to secure insurance-related contingent obligations.

During the year ended December 31, 2022, net cash provided by operating activities was $207.0 million, compared to net cash used in operating activities of $148.5 million in 2021, representing an increase of $355.5 million compared to 2021. The operating cash flow for 2022 was the largest result for any year since the merger between Tutor-Saliba Corporation and Perini Corporation in 2008. The record operating cash flow in 2022 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 improved collection activity, as reflected by a decrease in accounts receivable and an increase in billings in excess of costs and estimated earnings. During the year ended December 31, 2021, net cash used in operating activities was $148.5 million due primarily to investments in project working capital, partially offset by cash generated from earnings sources. The increase in working capital in 2021 primarily reflected a decrease in accounts payable due to timing of payments to suppliers and subcontractors and an increase in costs and estimated earnings in excess of billings (“CIE”). The increase in CIE was primarily due to the follow-on impacts of the COVID-19 pandemic, which caused delays in the negotiation and resolution of certain claims and unapproved change orders (due to the postponement or deferrals of certain legal and arbitration proceedings and settlement discussions), and constrained customers’ revenue and funding sources, thereby limiting their budgetary discretion to pay the Company for changes approved in scope but for which pricing was pending.

As noted above, cash flow from operating activities increased $355.5 million when comparing 2022 with 2021. The significant increase was primarily driven by a decrease in investment in working capital in 2022 compared to an increase in 2021. The decrease was largely due to improved collection activity, including collections associated with the continued resolution of certain claims and unapproved change orders that previously required the use of cash, as well as a smaller decrease in accounts payable in 2022 as compared to 2021 due primarily to the timing of payments to vendors and subcontractors. The increase driven by the changes in investment in working capital was partially offset by changes in cash from earnings sources.

During 2022 and 2021, we used $65.6 million and $37.3 million of net cash in investing activities, respectively. The net cash used in investing activities for 2022 and 2021 was primarily due to the acquisition of property and equipment (i.e., capital expenditures), which totaled $59.8 million and $38.6 million, respectively. The increase in capital expenditures in 2022 was primarily due to higher capital expenditures in 2022 related to project-specific equipment funded directly by our customers.

During 2022, net cash used in financing activities was $78.9 million, which was primarily driven by net repayment of borrowings of $38.3 million and $47.4 million of cash distributions to noncontrolling interests, partially offset by $8.7 million of cash contributions from noncontrolling interests. During 2021, net cash used in financing activities was $54.7 million, which was primarily driven by net repayment of borrowings of $37.0 million and $22.7 million of cash distributions to noncontrolling interests, partially offset by $7.0 million of cash contributions from noncontrolling interests.

As of December 31, 2022, we had working capital of $1.7 billion, a ratio of current assets to current liabilities of 1.87 and a ratio of debt to equity of 0.66 compared to working capital of $2.1 billion, a ratio of current assets to current liabilities of 2.17 and a ratio of debt to equity of 0.59 at December 31, 2021.

Debt

Summarized below are the key terms of our debt as of December 31, 2022. For additional information, refer to Note 7 of the Notes to Consolidated Financial Statements, as applicable.

2020 Credit Agreement

On August 18, 2020, the Company entered into a credit agreement (the “2020 Credit Agreement”) with 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”), with sublimits 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 and the Revolver will mature on August 18, 2025, in each case, unless any of the 2017 Senior Notes are outstanding on January 30, 2025 (which is 91 days prior to the maturity of the 2017 Senior Notes), in which case, both the Term Loan B and the Revolver will mature on January 30, 2025 (subject to certain further exceptions).

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, 2022, included in current maturities of long-term debt in the accompanying Consolidated Balance Sheets is an expected $44.0 million prepayment of principal on the Term Loan B that will become due in the second quarter of 2023. The prepayment results from our record operating cash flow in 2022, which produced “excess” cash flow under the terms of the 2020 Credit Agreement, as discussed above.

Borrowings under the 2020 Credit Agreement bear interest at variable rates, which increased during 2022 due to changes in market conditions that resulted in increases in LIBOR, in the case of the Term Loan B, and the administrative agent’s prime lending rate in the case of the Revolver. The average borrowing rates on the Term Loan B and the Revolver for the year ended December 31, 2022 were approximately 6.7% and 8.8%, respectively. At December 31, 2022, the borrowing rates on the Term Loan B and the Revolver were 9.1% and 11.3%, respectively. For more information regarding the terms of our 2020 Credit Agreement, refer to Note 7 of the Notes to 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:

On October 31, 2022, the 2020 Credit Agreement was amended to set the maximum First Lien Net Leverage Ratio covenant level to 2.75:1.00 (from 2.25:1.00), effective the fiscal quarter ending September 30, 2022, and subsequently stepping back down to 2.25:1.00 beginning the fiscal quarter ending June 30, 2023. 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 December 31, 2022, we were in compliance and expect to continue to be in compliance with the covenants under the 2020 Credit Agreement.

2017 Senior Notes

On April 20, 2017, the Company issued $500 million in aggregate principal amount of 6.875% Senior Notes due May 1, 2025 (the “2017 Senior Notes”) in a private placement offering. Interest on the 2017 Senior Notes is payable in arrears semi-annually in May and November of each year, beginning in November 2017.

Equipment Financing and Mortgages

The Company has certain loans entered into for the purchase of specific property, plant and equipment and secured by the assets purchased. The aggregate balance of equipment financing loans was approximately $37.0 million and $41.7 million at December 31, 2022 and 2021, respectively, with interest rates ranging from 2.54% to 7.32% with equal monthly installment payments over periods up to 5 years. The aggregate balance of mortgage loans was approximately $11.6 million and

27

Table of Contents

$14.6 million at December 31, 2022 and 2021, respectively, with interest rates ranging from a fixed 2.25% to Secured Overnight Financing Rate (“SOFR”) plus 2.00% and monthly installment payments over periods up to 10 years.

Contractual Obligations

Our contractual obligations and commitments as of December 31, 2022 include:

•Debt obligations of $972.4 million (of which $70.3 million are due in 2023) and interest payments of $240.8 million (of which $71.3 million are due in 2023) based on rates in effect as of December 31, 2022. See Note 7 of the Notes to Consolidated Financial Statements for further detail of our debt and the timing of expected future principal and interest payments.

•Operating lease obligations of $103.5 million (of which $12.4 million are due in 2023). See Note 9 of the Notes to Consolidated Financial Statements for further detail of our lease obligations and the timing of expected future payments.

Critical Accounting Estimates

Our discussion and analysis of our financial condition and results of operations is based upon our Consolidated Financial Statements, which have been prepared in accordance with GAAP. Our significant accounting policies are described in Note 1 of the Notes to Consolidated Financial Statements. The preparation of the Consolidated Financial Statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. Estimates are based on information available through the date of the issuance of the financial statements; accordingly, actual results in future periods could differ from these estimates. Significant judgments and estimates used in the preparation of the Consolidated Financial Statements apply to the following critical accounting policies:

Method of Accounting for Contracts — Contract revenue is recognized over time using the cost-to-cost method which measures progress towards completion based on the ratio of contract costs incurred to date compared to total estimated costs for each performance obligation. The estimates used in accounting for contracts with customers require judgment and assumptions regarding both future events and the evaluation of contingencies such as the impact of change orders, liability claims, other contract disputes, the achievement of contractual performance standards and potential variances in project schedule and costs. Changes to the total estimated contract cost, either due to unexpected events or revisions to management’s initial estimates, for a given project are recognized in the period in which they are determined.

In certain instances, we provide guaranteed completion dates and/or achievement of other performance criteria. Failure to meet schedule or performance guarantees could result in unrealized incentive fees and/or liquidated damages. In addition, depending on the type of contract, unexpected increases in contract cost may be unrecoverable, resulting in total cost exceeding revenue realized from the projects. The Company generally provides limited warranties for work performed, with warranty periods typically extending for a limited duration following substantial completion of the Company’s work on a project. Historically, warranty claims have not resulted in material costs incurred.

Claims arising from construction contracts have been made against the Company by customers, and the Company has made claims against customers for costs incurred in excess of current contract provisions. The Company recognizes revenue for claims as variable consideration in accordance with Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers (“ASC 606”). Assumptions as to the occurrence of future events and the likelihood and amount of variable consideration are made during the contract performance period. Estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of anticipated performance and all information (historical, current and forecasted) that is reasonably available to management. Estimated amounts are only included in the transaction price 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. Back charges to suppliers or subcontractors are recognized as a reduction of cost when it is determined that recovery of such cost is probable and the amounts can be reliably estimated. Disputed back charges are recognized when the same requirements described above for variable consideration have been satisfied.

See Executive Overview and Results of Segment Operations sections for further discussion and quantification of material charges related to changes in estimates resulting from legal judgments or decisions, settlements and other project charges.

Construction Joint Ventures — Certain contracts are executed through joint ventures. The arrangements are often formed for the execution of single contracts or projects and allow the Company to share risks and secure specialty skills required for project execution.

In accordance with ASC 810, Consolidation (“ASC 810”) the Company assesses its joint ventures at inception to determine if any meet the qualifications of a variable interest entity (“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 the joint venture is a VIE.

The Company also evaluates whether it is the primary beneficiary of each VIE and consolidates the VIE if the Company has both (a) the power to direct the economically significant activities of the entity and (b) the obligation to absorb losses of, or the right to receive benefits from, the entity 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 whether it qualifies as the primary beneficiary. The Company also considers all parties that have direct or implicit variable interests when determining whether it is the primary beneficiary. When the Company is determined to be the primary beneficiary, the VIE is consolidated. In accordance with ASC 810, management’s assessment of whether the Company is the primary beneficiary of a VIE is performed continuously.

For construction joint ventures that do not need to be fully consolidated, the Company accounts for its interest in the joint ventures using the proportionate consolidation method, whereby the Company’s proportionate share of the joint ventures’ assets, liabilities, revenue and cost of operations are included in the appropriate classifications in the Company’s consolidated financial statements. Intercompany balances and transactions are eliminated. See Note 1(b) and Note 13 of the Notes to Consolidated Financial Statements for additional discussion regarding VIEs.

Recoverability of Goodwill — Goodwill represents the excess of amounts paid over the fair value of net assets acquired from an acquisition. In order to determine the amount of goodwill resulting from an acquisition, we perform an assessment to determine the value of the acquired company's tangible and identifiable intangible assets and liabilities. In our assessment, we determine whether identifiable intangible assets exist, which typically include backlog, customer relationships and trade names.

We test goodwill for impairment annually as of October 1 of each year. This test requires us to estimate the fair value of each reporting unit carrying goodwill using income and market approaches, and to compare the calculated fair value of each reporting unit to its carrying value, which is equal to the reporting unit’s net assets. If the calculated fair value of a reporting unit is less than its carrying value, we recognize an impairment charge equal to the difference.

The impairment evaluation process requires assumptions that are subject to a high degree of judgment such as revenue growth rates, profitability levels, discount rates, industry market multiples and weighted-average cost of capital. Changes in these assumptions would impact the results of our impairment tests.

During interim periods, including those subsequent to the Company’s October 1 annual test date, we evaluate events and circumstances, including, but not limited to, an examination of macroeconomic conditions, cost factors, overall financial performance by each reporting unit, other relevant entity-specific events, and trends in the stock prices of our Company and peers to determine if such factors indicate that it is likely that the goodwill for one or more of our reporting units is impaired, thus warranting the performance of a quantitative impairment test sooner than the fourth quarter of the year.

During the fourth quarter of 2022, we conducted our annual goodwill impairment test and determined that goodwill was not impaired since the estimated fair value of the Civil reporting unit exceeded its net book value by a significant amount. However, there is a risk of goodwill impairment if future events are less favorable than what we assumed or estimated in our impairment analysis.

The Company has considered relevant events and circumstances since the annual goodwill impairment test, including, but not limited to, an examination of macroeconomic conditions, industry and market conditions, cost factors, overall financial performance by each reporting unit, other relevant entity-specific events, and trends in the stock prices of the Company and its peers. In considering the totality of qualitative factors known as of the reporting date, we determined that no triggering events occurred or circumstances changed since our October 1, 2022 annual test that would more likely than not reduce the fair value of the Civil reporting unit below its carrying amount. We will continue to monitor events occurring or circumstances changing which may suggest that goodwill should be reevaluated. These events and circumstances include, but are not limited to, changes in the overall financial performance of the Civil reporting unit and other quantitative and qualitative factors specific to the Civil reporting unit which indicate potential triggering events that would more likely than not reduce the fair value of the Civil reporting unit below its carrying amount.

could differ materially from those anticipated in the forward-looking statements as a result of certain factors, including, but not limited to, those discussed in Item 1A. Risk Factors and elsewhere in this Annual Report.

Comparison of 2020 to 2019 Results

For a discussion comparing our 2020 results to our 2019 results, refer to Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations in our Form 10-K for the year ended December 31, 2020, as filed with the Securities and Exchange Commission on February 24, 2021.

Our 2019 results of operations were negatively impacted by a $379.9 million pre-tax, non-cash goodwill impairment charge and a $166.8 million pre-tax charge related to the adverse SR 99 jury verdict. The goodwill impairment charge reduced income from construction operations for the Civil, Building and Specialty Contractors segments by $210.2 million, $13.5 million and $156.2 million, respectively, for the year ended December 31, 2019. The SR 99-related charge principally reduced revenue and income from construction operations in the Civil segment. For additional information on the goodwill impairment charge, refer to the Second Quarter of 2019 Goodwill Impairment discussion in Note 6 of the Notes to Consolidated Financial Statements. For additional information on the SR 99-related charge, refer to the Alaskan Way Viaduct Matter discussion in Note 8 of the Notes to Consolidated Financial Statements.

Executive Overview

COVID-19 Update

Since its onset in early 2020, the COVID-19 pandemic has caused occasional temporary shortages in available manpower, reductions in field labor productivity, other inefficiencies, delays to project schedules and deferrals of project execution. As a result, we continue to incur incremental costs, much of which we are seeking to recover from our customers as allowed by contractual terms. The relief sought from customers, together with certain incremental project opportunities that resulted from the pandemic, has helped to mitigate the pandemic's negative impact on our financial results. In addition, we have experienced delays in certain legal proceedings, as various courts and arbitrators process a large backlog of cases that were impacted by the pandemic. The COVID-19 pandemic has also hindered the Company’s ability to resolve unapproved work, resulting in the need for the Company to temporarily fund certain project costs that would normally be more promptly negotiated, billed to and collected from customers, which has largely contributed to an increase in costs and estimated earnings in excess of billings (“CIE”). These delays in resolving and recovering on such claims adversely affected our liquidity and financial results in 2021. However, we anticipate a significant improvement in the pace and magnitude of dispute resolutions and corresponding cash recoveries in 2022, assuming there is no worsening of the pandemic.

Throughout 2020 and much of 2021, the pandemic also adversely affected the volume and timing of our new awards, which has negatively impacted our backlog and operating results, and the negative impact on operating results in 2022 is expected to continue due to previously limited bidding and proposal opportunities. In addition, many of our state and local government customers’ revenue sources have been negatively impacted by the pandemic due to curtailed ridership on mass-transit systems (buses, subways, trains, etc.), travel on commercial airlines, and driving by the general public, which resulted in reduced fare and toll collections, lower fuel tax receipts and reduced airport and other facility usage fees. The significant revenue reductions experienced by some of our customers have adversely impacted their ability to pay the Company timely for amounts due. The revenue reductions have also led to, and could continue to result in, customers delaying bid solicitations and contract awards for some of their planned infrastructure projects. The potential for continued or new pandemic-related delays in project bids and awards could result in lower-than-expected revenue and earnings until such time as the substantial funding relating to the recently enacted federal infrastructure legislation is distributed to our customers.

Due to the continued fluidity of the COVID-19 pandemic, uncertainties as to its scope and duration, and ongoing changes in the way that governments, businesses and individuals respond to the pandemic, the Company is unable at this time to accurately predict the pandemic’s future impact on the Company’s business, results of operations, financial condition or liquidity.

Operating Results

Consolidated revenue for 2021 was $4.6 billion compared to $5.3 billion for 2020. The decrease was primarily due to reduced project execution activities in the Building segment, as various projects have completed or are nearing completion, while newer projects that have been recently awarded are yet to contribute meaningfully to revenue. Revenue for both 2020 and 2021 was negatively impacted by the COVID-19 pandemic, which resulted in delays in new awards. The pandemic also caused delays in the execution of certain projects, which negatively impacted revenue for both years.

19

Table of Contents

Income from construction operations for 2021 was $226.8 million compared to $262.3 million for 2020. The decrease was primarily due to the revenue decline discussed above, as well as various unfavorable impacts due to changes in estimates totaling $63.1 million on a transportation project in the Northeast that affected all three segments and a separate $16.2 million impact due to a change in estimate on a Specialty Contractors segment mass-transit project. These changes in estimates reflected the temporary negative impact to earnings from growth in unapproved change orders, which resulted in a reduction in the projects’ percentage of completion (and, correspondingly, a reduction in the percentage of estimated profit recognized for the year ended December 31, 2021 for these projects), and, to a lesser degree, project charges. The temporary reduction to earnings is expected to reverse itself as the projects progress toward completion and the negotiation and settlement of the unapproved change orders could result in additional profit for the incremental work. The decrease was partially offset by favorable impacts due to changes in estimates totaling $45.3 million on certain Civil segment mass-transit projects and a $20.1 million favorable adjustment related to a legal judgment on a completed project in the Specialty Contractors segment. Further details are provided below in the Results of Segment Operations section.

The effective income tax rate for 2021 was 16.0% compared to 12.6% for 2020. The lower effective tax rate in 2020 primarily reflects one-time tax benefits related to provisions of the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”). See Corporate, Tax and Other Matters below for a discussion of the changes in the effective tax rate.

Diluted earnings per share for 2021 was $1.79 compared to diluted earnings per share of $2.12 for 2020. The decrease in 2021 was principally due to the factors discussed above that drove the decrease in income from construction operations, as well as the higher effective tax rate in 2021 compared to 2020.

Consolidated new awards in 2021 were $4.5 billion compared to $2.4 billion in 2020. The increase in new awards in 2021 was primarily due to the impacts of the COVID-19 pandemic in 2020, which delayed certain customers from moving forward with planned project bid solicitations and contract awards until 2021 and beyond, due to budgetary impacts, funding uncertainties and customer staffing challenges. The Building and Civil segments were the primary contributors to the new award activity in 2021. Significant new awards included the Cedars-Sinai Marina del Rey Hospital in California (contract value was not publicly announced); the $471 million LAX Airport Metro Connector project; $434 million for various Civil segment projects in the Midwest; more than $385 million of additional funding for certain mass-transit projects in California; the $269 million Yountville Veterans Home in California; the $220 million I-70 Missouri River Bridge project; the $162 million Tinian International Airport aircraft parking apron and taxiway project in the Northern Mariana Islands; the $152 million Santa Rosa Courthouse project in California; and a $122 million military range project and a $98 million military housing project, both in Guam.

Consolidated backlog as of December 31, 2021 was $8.2 billion, essentially level compared to $8.3 billion as of December 31, 2020. Backlog for both 2020 and 2021 was negatively impacted by the COVID-19 pandemic due to reduced bidding and proposal activity. In addition, the Company’s lack of success in its pursuit of certain large prospective Civil segment projects in the second half of 2021 also negatively impacted backlog. As of December 31, 2021, the mix of backlog by segment was 55% for Civil, 28% for Building and 17% for Specialty Contractors, compared to 57% for Civil, 20% for Building and 23% for Specialty Contractors at the end of 2020. Importantly, Building segment backlog, which carries a substantially lower margin, increased $607 million year-over-year, whereas backlog for the higher-margin Civil and Specialty Contractors segments declined $230 million and $487 million, respectively, year-over-year.

Most projects in the Civil segment’s backlog typically convert to revenue over a period of three to five years and in the Building and Specialty Contractors segments over a period of one to three years. We estimate that approximately $4 billion, or 46%, of our backlog as of December 31, 2021 will be recognized as revenue in 2022. As a result of the changes in the backlog mix and the rate of conversion from backlog to revenue discussed above, we anticipate that in 2022 the Building segment will contribute proportionately higher revenue at a lower operating margin relative to contributions from the Civil and Specialty Contractors segments.

Table of Contents

The following table presents the changes in backlog in 2021:

_____________________________________________________________________________________________________________

(a)New awards consist of the original contract price of projects added to our 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 Consolidated Financial Statements. Such differences relate to the timing of executing a formal contract or receiving a notice to proceed. More specifically, backlog sometimes 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).

The outlook for the Company’s growth over the next several years remains favorable, but the impact of the COVID-19 pandemic could continue to adversely affect performance and operations, and the amount and timing of new work awarded. In addition, the Company’s growth could continue to be impacted by future project delays or the timing of project commencements, ramp-up activities and completions. We anticipate that we will continue to win our share of significant new awards resulting from long-term 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 several years, voters in numerous states approved dozens of long-term transportation funding measures totaling approximately $200 billion in long-term funding. The largest of these was in Los Angeles County, where Measure M, a half-cent sales tax increase, was approved and is expected to generate $120 billion of funding over 40 years. In addition, California's Senate Bill 1, which was signed into law in 2017, is providing an average of $5.4 billion annually through 2027 for various transportation, mass-transit and bridge projects. Interest rates have remained near historically low levels, which may be conducive to continued, and potentially increased, spending on infrastructure projects if borrowing rates remain at relatively low levels following anticipated interest rate increases by the Federal Reserve in 2022.

As discussed above, the IIJA was enacted into law on November 15, 2021, and it 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 IIJA marks 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, and much of it will be invested 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 will favorably impact the Company’s current work and prospective opportunities over the next decade.

The Company has certain large Civil segment projects in the Northeast that completed or were nearing completion in 2021. The Company is pursuing several large prospective projects on the West Coast, in the Northeast and in Guam that are expected to be bid and/or awarded in 2022 and 2023. However, the timing and magnitude of revenue contributions from these prospective projects may not fully offset revenue reductions associated with the projects that have completed or are progressing toward completion in 2021. In addition, as discussed above, the COVID-19 pandemic has resulted in, and could again result in, delays in the bidding and awarding of certain projects the Company is pursuing, which may further delay large, new revenue streams.

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:

Revenue for 2021 decreased 5% compared to 2020. The decrease was primarily due to reduced project execution activities on various completed or nearly completed projects in the Northeast, partially offset by increased activities on various projects in California and Guam. Revenue for both 2020 and 2021 was reduced by the aforementioned COVID-19 impacts.

Income from construction operations for 2021 increased 8% compared to 2020. Despite the modest revenue decline, income from construction operations increased primarily due to $29.0 million of favorable adjustments on a mass‐transit project and $16.3 million of favorable adjustments on another mass-transit project, both reflecting improved profitability as a result of the negotiation and settlement of certain change orders in 2021. The increase was partially offset by a $13.3 million negative impact due to changes in estimates on a transportation project in the Northeast that included a charge and the temporary negative impact to earnings from growth in unapproved change orders.

Operating margin was 12.7% for 2021 compared to 11.2% in 2020. The increase in operating margin for 2021 was primarily due to the factors discussed above that drove the increase in income from construction operations.

New awards in the Civil segment totaled $1.9 billion in 2021 compared to $946 million in 2020. As discussed earlier, the larger volume of new awards in 2021 was primarily due to the impacts of the COVID-19 pandemic, which delayed the bidding and awards for various projects until 2021 and beyond. In spite of the improvement in new award activity in 2021, the level of new awards was negatively impacted by the Company’s lack of success in its pursuit of certain large Civil segment projects in the second half of 2021. New awards in 2021 included $434 million for various Civil segment projects in the Midwest; more than $385 million of additional funding for certain mass-transit projects in California; the $220 million I-70 Missouri River Bridge project; the $162 million Tinian International Airport aircraft parking apron and taxiway project in the Northern Mariana Islands; and a $122 million military range project and a $98 million military housing project, both in Guam. The COVID-19 pandemic has resulted in significant revenue shortfalls for many state and local government agencies since 2020, and could continue to cause deferrals or cancellations of certain new projects, depending on the allocation and prioritization of state and local funding, as well as the availability, timing and magnitude of anticipated funding from the federal government, including funding from the recently enacted IIJA.

New awards in 2020 included more than $732 million of additional funding for various mass-transit projects, the Company’s $121 million share of a joint-venture mass-transit project in Massachusetts, and a $64 million mining project in Alabama.

Backlog for the Civil segment was $4.6 billion as of December 31, 2021, a modest decrease of 5% compared to $4.8 billion as of December 31, 2020. 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 IIJA, 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 from construction operations for the Building segment are summarized as follows:

22

Table of Contents

Revenue for 2021 decreased 28% compared to 2020, primarily due to reduced project execution activities on certain projects in California and Oklahoma that are completed or nearing completion. Revenue for both 2020 and 2021 was reduced by the aforementioned COVID-19 impacts.

Income from construction operations for 2021 decreased 46% compared to 2020, primarily due to volume reductions mentioned above, as well as a $13.3 million negative impact due to changes in estimates on a transportation project in the Northeast that included a charge and the temporary negative impact to earnings from growth in unapproved change orders.

Operating margin was 2.0% in 2021 compared to 2.7% in 2020. The decrease in operating margin was driven by the factors mentioned above that drove the lower revenue and income from construction operations.

New awards in the Building segment totaled $2.0 billion in 2021 compared to $897 million in 2020. The substantially increased level of new awards in 2021 was due to delays of certain new awards in 2020 that resulted from impacts of the COVID-19 pandemic. New awards in 2021 included the Cedars-Sinai Marina del Rey Hospital in California (contract value was not publicly announced); the $471 million LAX Airport Metro Connector project; the $269 million Yountville Veterans Home in California; and the $152 million Santa Rosa Courthouse project in California. The COVID-19 pandemic could continue to result in certain delayed project opportunities.

New awards in 2020 included approximately $615 million for various building projects in California and $271 million for several government facilities projects nationwide.

Backlog for the Building segment was $2.3 billion as of December 31, 2021, an increase of 36% compared to $1.7 billion as of December 31, 2020. The increase was driven by the heightened new award activity mentioned above. The Building segment continues to have a large volume of prospective projects across various end markets and geographic locations. We expect demand to grow as economic conditions remain conducive to increased customer spending on new building facilities and renovations to existing buildings, supported by what has been and is expected to remain a favorable, relatively low interest rate environment despite the prospect of higher interest rates in 2022. However, the COVID-19 pandemic has resulted in, and could continue to result in, reduced demand for our building construction services.

Specialty Contractors Segment

Revenue and income (loss) from construction operations for the Specialty Contractors segment are summarized as follows:

Revenue for 2021 declined slightly compared to 2020. Revenue for 2020 and 2021 was reduced by the aforementioned COVID-19 impacts.

Loss from construction operations for 2021 was $10.0 million compared to income from construction operations of $17.2 million for 2020. The change was due to negative impacts of $19.0 million and $17.6 million on the mechanical and electrical components, respectively, of a transportation project in the Northeast and $16.2 million on an electrical mass-transit project also in the Northeast, all of which were due to changes in estimates that included charges and/or the temporary negative impact to earnings from growth in unapproved change orders. The decrease was partially offset by a $20.1 million favorable adjustment related to a legal judgment on a completed electrical project in New York, as well as the absence of the following largely offsetting items that had a net negative impact on the Company’s results in 2020: a $25.7 million prior-year gain as a result of a favorable arbitration decision and subsequent settlement of the related employment dispute, a $15.2 million prior-year unfavorable legal ruling pertaining to a mechanical project in California and a $13.2 million prior-year impact from an adverse arbitration ruling related to another electrical project in New York.

Operating margin was (0.9)% in 2021 compared to 1.5% in 2020. The decrease in operating margin was mainly attributable to the aforementioned factors that drove the lower income from construction operations.

New awards in the Specialty Contractors segment totaled $631 million in 2021 compared to $600 million in 2020. New awards in 2021 were mostly comprised of $370 million for various electrical and mechanical projects in the Northeast, and $260 million for various electrical and mechanical projects in Florida, Texas and California. The COVID-19 pandemic has resulted in, and could continue to result in, reduced demand from certain commercial and government customers that have been experiencing funding constraints.

23

Table of Contents

New awards in 2020 included $286 million for various electrical projects in Texas, California and Florida, and $158 million for various electrical projects in New York.

Backlog for the Specialty Contractors segment was $1.4 billion as of December 31, 2021, a decrease of 26% compared to $1.9 billion as of December 31, 2020. The decrease corresponds with the reduction in Civil segment backlog, as certain large Civil segment projects that were not awarded to the Company would have included substantial amounts of subcontract work for the Specialty Contractors segment. The decrease is also due to lower demand from certain customers, particularly in New York, that have experienced adverse budgetary impacts as a result of the COVID-19 pandemic and that have consequently delayed and/or reduced certain spending. The Specialty Contractors segment continues to be increasingly focused on servicing the Company’s backlog of large Civil and Building segment projects, but also remains well-positioned to capture its share of new projects for external customers, 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 $58.0 million in 2021 compared to $53.9 million in 2020. The increase in corporate general and administrative expenses in 2021 was predominantly due to higher travel-related expenses compared to 2020, when the COVID-19 pandemic caused significant travel reductions.

Other Income (Expense), Interest Expense and Income Tax Expense

Net other income for 2021 was $2.0 million compared to net other expense of $11.9 million for 2020. The improvement in 2021 was primarily due to the absence of charges incurred in 2020 related to the unfavorable resolutions of certain disputes pertaining to past business acquisitions, which were not material.

Interest expense decreased $7.2 million in 2021 compared to 2020. The decrease in 2021 was primarily due to the absence of extinguishment costs recognized in 2020 related to debt refinancing.

The effective income tax rate was 16.0% for 2021 compared to 12.6% for 2020. The 2021 effective income tax rate reflects an $8.2 million benefit related to a federal claim of right tax credit, which resulted in a tax rate adjustment associated with an adverse 2019 jury verdict that rendered certain income recognized in 2016 to be uncollectible.

The effective income tax rate for 2020 primarily reflected the favorable tax rate differential realized on the 2019 net operating loss (“NOL”) carryback. Under the CARES Act, enacted on March 27, 2020, the NOL generated in 2019 may be carried back up to five years, whereas under previous rules NOLs were only allowed to be carried forward. This allowed the Company to realize the benefit of the tax rate differential by carrying back the NOL to tax years when the federal statutory tax rate was 35% rather than the current rate of 21%. For a further discussion of income taxes, refer to Note 5 of the Notes to Consolidated Financial Statements.

The effective income tax rates for 2021 and 2020 were unfavorably impacted by state income taxes and favorably impacted by earnings attributable to noncontrolling interests, for which income taxes are not the responsibility of the Company.

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 million, with sublimits 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, 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 of $148 million and available cash balances as of December 31, 2021, will be sufficient to fund any working capital needs and debt maturities for the next 12 months and beyond, provided that we are not adversely impacted by unanticipated future events, including further impacts related to the COVID-19 pandemic as discussed above in COVID-19 Update. Liquidity has been, and could continue to be, adversely impacted by our inability to collect cash due to the follow-on impacts of

24

Table of Contents

COVID-19, which have constrained certain customers’ funding sources and delayed their ability to make payments on approved contract work. As discussed above in COVID-19 Update, the COVID-19 pandemic has delayed court and arbitration schedules and also hindered the Company’s ability to resolve unapproved work, which has largely contributed to an increase in CIE. We believe that the follow-on impacts of COVID-19 could be alleviated with the anticipated funding from the IIJA, as discussed above, and the relief of customers’ revenue and funding constraints as travel and commuting continue to resume, providing higher fare, toll and fuel tax revenue. Furthermore, the bottleneck of accumulated court and arbitration proceedings that grew during 2020 and 2021 due to the pandemic has recently begun to alleviate, although the timing of resolution and collection of amounts due to the Company related to such matters remains uncertain. We anticipate substantially improved operating cash generation in 2022 compared to 2021, as a result of projected cash collections, both from project execution activities and the resolution of various outstanding claims and change orders.

Cash and Working Capital

Cash and cash equivalents were $202.2 million as of December 31, 2021 compared to $374.3 million as of December 31, 2020. Cash immediately available for general corporate purposes was $60.2 million and $210.8 million as of December 31, 2021 and 2020, 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 was available only for joint venture-related uses, including distributions to joint venture partners. In addition, our restricted cash and restricted investments totaled $93.6 million as of December 31, 2021 compared to $156.5 million as of December 31, 2020. Restricted cash and restricted investments are primarily held to secure insurance-related contingent obligations. Restricted cash as of December 31, 2020 also included $69.9 million of cash held to repay the outstanding principal balance of the Convertible Notes, which were repaid at maturity on June 15, 2021 (see Note 7 of the Notes to Consolidated Financial Statements).

During the year ended December 31, 2021, net cash used in operating activities was $148.5 million due primarily to investments in project working capital, partially offset by cash generated from earnings sources. The increase in working capital in 2021 primarily reflects a decrease in accounts payable due to timing of payments to suppliers and subcontractors and an increase in CIE. The increase in CIE was primarily due to the follow-on impacts of the COVID-19 pandemic, which has caused delays in the negotiation and resolution of certain claims and unapproved change orders (due to the postponement or deferrals of certain legal and arbitration proceedings and settlement discussions, which have recently begun to resume), and constrained customers’ revenue and funding sources, thereby limiting their budgetary discretion to pay the Company for changes approved in scope but for which pricing is pending. As discussed above, we expect the follow-on impacts of COVID-19 to ease as a result of anticipated funding from the IIJA and improved customer revenue and funding sources. During the year ended December 31, 2020, net cash provided by operating activities was $172.8 million due primarily to cash generated from earnings sources, partially offset by investment in working capital.

The $321.3 million decrease in cash provided by operating activities when comparing 2021 with 2020 substantially reflects an increased investment in working capital principally as a result of a current-year decrease in accounts payable compared to an increase in the prior year due to timing of payments to vendors and subcontractors, partially offset by a current-year decrease in retainage receivable compared to an increase in the prior year.

During 2021 and 2020, we used $37.3 million and $46.4 million of cash from investing activities, respectively. The net cash used in investing activities for 2021 and 2020 was primarily due to the acquisition of property and equipment for projects, which totaled $38.6 million and $54.8 million, respectively. The decrease in capital expenditures in 2021 was primarily due to higher capital expenditures in 2020 related to project-specific equipment funded directly by our customers.

During 2021, net cash used in financing activities was $54.7 million, which was primarily driven by net repayment of borrowings of $37.0 million and $22.7 million of cash distributions to noncontrolling interests, partially offset by $7.0 million of cash contributions from noncontrolling interests. During 2020, net cash provided by financing activities was $123.3 million, which was primarily driven by increased net borrowings of $181.4 million, partially offset by $48.5 million of cash distributions to noncontrolling interests and debt issuance costs of $11.2 million.

As of December 31, 2021, we had working capital of $2.1 billion, a ratio of current assets to current liabilities of 2.17 and a ratio of debt to equity of 0.59 compared to working capital of $1.8 billion, a ratio of current assets to current liabilities of 1.80 and a ratio of debt to equity of 0.66 at December 31, 2020.

Debt

Summarized below are the key terms of our debt as of December 31, 2021. For additional information, refer to Note 7 of the Notes to Consolidated Financial Statements, as applicable.

2020 Credit Agreement

On August 18, 2020, the Company entered into a credit agreement (the “2020 Credit Agreement”) with 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 “2020 Revolver”), with sublimits 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 and the 2020 Revolver will mature on August 18, 2025, in each case, unless any of the 2017 Senior Notes are outstanding on January 30, 2025 (which is 91 days prior to the maturity of the 2017 Senior Notes), in which case, both the Term Loan B and the 2020 Revolver will mature on January 30, 2025 (subject to certain further exceptions). For more information regarding the terms of our 2020 Credit Agreement, refer to Note 7 of the Notes to 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:

As of December 31, 2021, we were in compliance and expect to continue to be in compliance with the covenants under the 2020 Credit Agreement.

On August 19, 2020, the Company used proceeds from the Term Loan B to repurchase $130.1 million aggregate principal amount of the Convertible Notes for an aggregate purchase price of $132.4 million (including accrued and unpaid interest to the repurchase date). The Company repaid the remaining principal balance of the Convertible Notes at maturity on June 15, 2021 using proceeds from the Term Loan B, which were held in a restricted cash account for this purpose. None of the Convertible Notes remained outstanding as of December 31, 2021.

2017 Senior Notes

On April 20, 2017, the Company issued $500 million in aggregate principal amount of 6.875% Senior Notes due May 1, 2025 (the “2017 Senior Notes”) in a private placement offering.

Critical Accounting Estimates

Our discussion and analysis of our financial condition and results of operations is based upon our Consolidated Financial Statements, which have been prepared in accordance with GAAP. Our significant accounting policies are described in Note 1 of the Notes to Consolidated Financial Statements. The preparation of the Consolidated Financial Statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. Estimates are based on information available through the date of the issuance of the financial statements; accordingly, actual results in future periods could differ from these estimates. Significant judgments and estimates used in the preparation of the Consolidated Financial Statements apply to the following critical accounting policies:

Method of Accounting for Contracts — Contract revenue is recognized over time using the cost-to-cost method which measures progress towards completion based on the ratio of contract costs incurred to date compared to total estimated costs for each performance obligation. The estimates used in accounting for contracts with customers require judgment and assumptions regarding both future events and the evaluation of contingencies such as the impact of change orders, liability claims, other contract disputes, the achievement of contractual performance standards and potential variances in project schedule and costs. Changes to the total estimated contract cost, either due to unexpected events or revisions to management’s initial estimates, for a given project are recognized in the period in which they are determined.

In certain instances, we provide guaranteed completion dates and/or achievement of other performance criteria. Failure to meet schedule or performance guarantees could result in unrealized incentive fees and/or liquidated damages. In addition, depending on the type of contract, unexpected increases in contract cost may be unrecoverable, resulting in total cost exceeding revenue realized from the projects. The Company generally provides limited warranties for work performed, with warranty periods typically extending for a limited duration following substantial completion of the Company’s work on a project. Historically, warranty claims have not resulted in material costs incurred.

Claims arising from construction contracts have been made against the Company by customers, and the Company has made claims against customers for costs incurred in excess of current contract provisions. The Company recognizes revenue for claims as variable consideration in accordance with Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers (“ASC 606”). Assumptions as to the occurrence of future events and the likelihood and amount of variable consideration are made during the contract performance period. Estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of anticipated performance and all information (historical, current and forecasted) that is reasonably available to management. Estimated amounts are only included in the transaction price 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. Back charges to suppliers or subcontractors are recognized as a reduction of cost when it is determined that recovery of such cost is probable and the amounts can be reliably estimated. Disputed back charges are recognized when the same requirements described above for variable consideration have been satisfied.

Construction Joint Ventures — Certain contracts are executed through joint ventures. The arrangements are often formed for the execution of single contracts or projects and allow the Company to share risks and secure specialty skills required for project execution.

In accordance with ASC 810, Consolidation (“ASC 810”) the Company assesses its joint ventures at inception to determine if any meet the qualifications of a variable interest entity (“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 the joint venture is a VIE.

The Company also evaluates whether it is the primary beneficiary of each VIE and consolidates the VIE if the Company has both (a) the power to direct the economically significant activities of the entity and (b) the obligation to absorb losses of, or the right to receive benefits from, the entity 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 whether it qualifies as the primary beneficiary. The Company also considers all parties that have direct or implicit variable interests when determining whether it is the primary beneficiary. When the Company is determined to be the primary beneficiary, the VIE is consolidated. In accordance with ASC 810, management’s assessment of whether the Company is the primary beneficiary of a VIE is performed continuously.

For construction joint ventures that do not need to be fully consolidated, the Company accounts for its interest in the joint ventures using the proportionate consolidation method, whereby the Company’s proportionate share of the joint ventures’ assets, liabilities, revenue and cost of operations are included in the appropriate classifications in the Company’s consolidated financial statements. Intercompany balances and transactions are eliminated. See Note 1(b) and Note 13 of the Notes to Consolidated Financial Statements for additional discussion regarding VIEs.

Recoverability of Goodwill — Goodwill represents the excess of amounts paid over the fair value of net assets acquired from an acquisition. In order to determine the amount of goodwill resulting from an acquisition, we perform an assessment to determine the value of the acquired company's tangible and identifiable intangible assets and liabilities. In our assessment, we determine whether identifiable intangible assets exist, which typically include backlog, customer relationships and trade names.

We test goodwill for impairment annually as of October 1 of each year. This test requires us to estimate the fair value of each reporting unit carrying goodwill using income and market approaches, and to compare the calculated fair value of each reporting unit to its carrying value, which is equal to the reporting unit’s net assets. If the calculated fair value of a reporting unit is less than its carrying value, we recognize an impairment charge equal to the difference.

The impairment evaluation process requires assumptions that are subject to a high degree of judgment such as revenue growth rates, profitability levels, discount rates, industry market multiples and weighted-average cost of capital. Changes in these assumptions would impact the results of our impairment tests.

During interim periods, including those subsequent to the Company’s October 1 annual test date, we evaluate events and circumstances, including, but not limited to, an examination of macroeconomic conditions, cost factors, overall financial performance by each reporting unit, other relevant entity-specific events, and trends in the stock prices of our Company and peers to determine if such factors indicate that it is likely that the goodwill for one or more of our reporting units is impaired, thus warranting the performance of a quantitative impairment test sooner than the fourth quarter of the year. The Company performed an interim impairment test as of June 1, 2019 and recognized a non-cash impairment loss totaling $379.9 million, which eliminated the carrying value of goodwill for the Building and Specialty Contractors reporting units. See Note 1(g) and Note 6 of the Notes to Consolidated Financial Statements.

During the fourth quarter of 2021, we conducted our annual goodwill impairment test and determined that goodwill was not impaired since the estimated fair value of the Civil reporting unit exceeded its net book value by a significant amount. As such, there is a risk of goodwill impairment if future events are less favorable than what we assumed or estimated in our impairment analysis.

The Company has considered relevant events and circumstances since the annual goodwill impairment test, including, but not limited to, an examination of macroeconomic conditions, industry and market conditions, impacts from the COVID-19 pandemic, cost factors, overall financial performance by each reporting unit, other relevant entity-specific events, and trends in the stock prices of the Company and its peers. In considering the totality of qualitative factors known as of the reporting date, we determined that no triggering events occurred or circumstances changed since our October 1, 2021 annual test that would more likely than not reduce the fair value of the Civil reporting unit below its carrying amount. We will continue to monitor events occurring or circumstances changing which may suggest that goodwill should be reevaluated. These events and circumstances include, but are not limited to, changes in the overall financial performance of the Civil reporting unit, impacts to our business as a result of the COVID-19 pandemic, as well as other quantitative and qualitative factors specific to the Civil reporting unit which indicate potential triggering events that would more likely than not reduce the fair value of the Civil reporting unit below its carrying amount.
