For a discussion comparing our 2022 results to our 2021 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, 2022, as filed with the SEC on March 15, 2023.

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.

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.

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

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.
