Item 1A. RISK FACTORS

56 rewritten, 29 added, 15 removed, 240 unchanged

Rewritten

*Economic [removed: downturns] [added: downturns, recessions, or periods of slow growth] have historically led to reductions in demand for our services.

Rewritten

Negative conditions in the credit markets, including [removed: rising] [added: elevated] interest rates, may adversely impact our results of operations and our ability to operate our business.* The level of demand from our clients for our services has been, in the past, adversely impacted by slowdowns in the industries we service, as well as in the economy in general.

Rewritten

When the general level of economic activity has [removed: been reduced] [added: declined] from historical levels, certain of our ultimate customers have delayed or canceled projects or capital spending, especially with respect to more profitable private sector work, and such slowdowns adversely affect our ability to grow, reducing our revenues and profitability.

Rewritten

A prolonged stagnation or weakening in financial and macroeconomic conditions, [added: potentially] including [removed: rising] [added: higher] interest rates, supply chain challenges, inflation, [removed: and any continuing impacts of the COVID-19 pandemic,] [added: or geopolitical impacts,] could therefore have a significant adverse effect on our revenues and profitability.

Rewritten

Increases in benchmark interest rates impact our interest expense and cost of capital, which may adversely impact our ability to make payments on future outstanding debt, raise funds through the issuance of debt, fund capital expenditures or [added: meet] other liquidity needs.

Rewritten

[removed: Continued volatility] [added: Volatility] within these markets, including the impact of geopolitical [removed: instability,] [added: instability (such as disruption of shipping lanes),] could negatively impact our financial position, results of operations, and cash flows.

Rewritten

[Table of [removed: Contents](#i5b93746942b5441a93c12246ba215868_7)][added: Contents](#iff155233dd944a23b1f9264cd2aff3a6_7)]

Rewritten

Our business may be adversely affected by significant reductions in government spending, delays or disruptions in the government appropriations process or the failure to [added: fully] fund or implement [removed: recent legislation, including] [added: legislation such as] the CHIPS and Science Act of 2022 and the Inflation Reduction [removed: Act, both of which could benefit our business.][added: Act.]

Rewritten

As a result, reduced or delayed spending by the federal government and/or state and local [removed: governments] [added: governments, potentially including the reduction or elimination of funding for projects or other benefits under relevant legislation,] may have a material and adverse impact on our business, financial condition, results of operations, and cash flows.

Rewritten

Significant reductions in spending aimed at reducing federal, state, or local budget deficits, the absence of a bipartisan agreement on the federal government's budget or raising the debt ceiling (and any disruption caused by a federal government shutdown as a result thereof), [removed: renewed focus on budget deficits following increases in government spending in response to the COVID-19 pandemic,] personnel reductions, [added: elimination of government agencies or programs,] the closure of government facilities and offices, or other changes in budget priorities could result in the deferral, delay, disruption, or cancellation of projects or contracts that we might otherwise have sought to perform.

Rewritten

*Volatility in the prices or availability of certain materials and equipment used in our businesses and those of our customers, including as a result of inflation, [added: supply chain disruptions,] geopolitical instability, and protectionist trade measures, could adversely affect our businesses.* We are exposed to market risk of increases in certain commodity prices of materials, such as copper and steel, which are used as components of supplies or materials utilized in our operations.

Rewritten

We are also exposed to increases in energy prices, particularly as they relate to gasoline prices for our fleet of approximately [removed: 13,800] [added: 14,000] vehicles.

Rewritten

Further, the timing of our price increases may lag the timing of the underlying increases in commodity or material [added: prices and our fixed price contracts generally do not allow us to adjust our] prices.

Rewritten

[removed: Additionally, our fixed price contracts generally do not allow us to adjust our prices and, as] [added: As] a result, increases in material or fuel costs could reduce our profitability with respect to projects in progress.

Rewritten

Fluctuations in the price of energy and commodity materials, whether resulting from fluctuations in market supply or demand, geopolitical [removed: conditions, including] [added: conditions (including] supply chain [removed: disruptions and] [added: disruptions,] sanctions on Russian exports as a result of Russia’s invasion of [removed: Ukraine] [added: Ukraine, armed conflict between Israel] and [removed: recent] [added: Iran, and] shipping lane disruptions following maritime attacks in the Gulf of [removed: Aden,] [added: Aden and the Red Sea),] an increase in trade protection measures such as tariffs, or the disruption, modification, or cancellation of multilateral trade agreements, may adversely affect our customers and as a result cause them to curtail the use of our services.

Rewritten

*The loss of [removed: one or a few] customers could have an adverse effect on us.* Although we provide services to a diverse portfolio of end markets and have long-standing relationships with many of our significant customers, our customers may unilaterally reduce, fail to renew, or terminate their contracts with us at any time.

Rewritten

Certain of our competitors have lower overhead cost structures and, therefore, are able to provide their services at lower rates than we are [added: currently able to provide.]

Rewritten

If we are unable to compete effectively, we may experience a loss of [removed: market share,] [added: customers,] reduced profitability, or both, which if significant, could have a material adverse effect on our business, financial condition, and results of operations.

Rewritten

The actual cost of labor and materials, however, may vary from the costs we originally estimated, something which we have experienced and may continue to experience due to inflationary pressures, supply chain challenges, and [removed: rising] [added: elevated] interest rates.

Rewritten

[removed: Such requirements have become more frequent in recent years and we expect them to be increasingly prevalent, especially under the current administration in Washington, D.C.] If we subsequently fail to meet such guarantees, or comply with such provisions, we may be held responsible for costs resulting from such failures, including payment of penalties or liquidated or other damages.

Rewritten

*Many of our contracts, especially our building and industrial services contracts, may be canceled or delayed on short notice, and we may be unsuccessful in replacing such contracts if they are canceled or as they are completed or expire.* For example, in [added: 2024 and] 2023, our United States building services segment and our United Kingdom building services segment were unsuccessful in retaining certain contracts upon rebid.

Rewritten

*Fluctuating foreign currency exchange rates impact our financial results.* We have operations in the United Kingdom, which in [removed: 2023] [added: 2024] accounted for approximately 3% of our revenues.

Rewritten

The factors that impact exchange rate fluctuation, including macroeconomic and geopolitical conditions, are outside [removed: the control] of [removed: the Company.][added: our control.]

Rewritten

*As part of our risk management strategy, we are effectively self-insured against certain potential liabilities.* Although we maintain insurance policies with respect to a broad range of risks, including automobile liability, general liability, workers’ compensation, and [removed: employee-related healthcare,] [added: property damage,] these policies do not cover all possible claims and certain of the policies are subject to large deductibles and retentions.

Rewritten

Additionally, circumstances beyond our control, such as [removed: rising] [added: elevated] interest rates, inflation and potential [removed: disruptions resulting from public health emergencies, such as those experienced in connection with the COVID-19 pandemic,] [added: macroeconomic disruptions,] may hinder our ability to pursue and complete acquisitions.

Rewritten

Further, realization of the anticipated benefits of an [removed: acquisition,] [added: acquisition such as our acquisition of Miller Electric Company,] and avoiding or mitigating the potential risks associated with an acquisition, will depend, among other things, upon our ability to: (a) effectively conduct due diligence to identify and mitigate potential problems at companies we propose to acquire, (b) recognize incompatibilities or other obstacles to the successful integration of the acquired business with our other operations, and (c) gain greater efficiencies and scale that will translate into reduced costs or anticipated synergies in a timely manner.

Rewritten

*We are increasingly dependent on sophisticated information technology systems; our business and results of operations are subject to adverse impacts due to [added: the] disruption, failure, [removed: and cybersecurity] [added: or] breaches of these systems.* We and our customers and third-party providers rely on information technology systems, hardware, and software, including [removed: third party] [added: third-party] “cloud based” systems, to run critical accounting, project management, and financial information systems.

Rewritten

However, our information technology systems and data, and that of our customers and third-party providers, are subject to cybersecurity incidents, such as hacking, computer viruses or other malicious or destructive software, ransomware, denial of service attacks, malicious social engineering and other intrusions, encryption, erasure, failure, and damage by individuals (which may include our and our [removed: third party] [added: third-party] providers’ employees), groups or nation states or state-sponsored threats.

Rewritten

While we maintain insurance coverage for these types of cybersecurity incidents, such policies may not completely provide coverage for, or completely offset, the costs associated with such incidents, including losses from [added: delays in our ability to provide services to our customers,] reputational [removed: harm] [added: harm,] or the costs to improve security against future similar threats.

Rewritten

The proper functioning of our information technology systems could also be impacted by other causes and circumstances beyond our control, including malware embedded in [removed: third party] [added: third-party] applications, the decision by software vendors to discontinue further development, integration, or long-term software maintenance support for our information systems, or hardware interruption, damage or disruption as a result of power outages, natural disasters, or computer network failures.

Rewritten

[removed: Unsettled regulations and case law regarding the ownership of intellectual property generated or] used by AI could also expose us to claims of copyright or license infringement or other liability resulting from our use of such tools.

Rewritten

In addition, [removed: new or evolving] laws and regulations governing data privacy and the unauthorized disclosure of confidential information, including the European Union General Data Protection Regulation ("GDPR"), the California Consumer Privacy Act, the California Privacy Rights Act, state biometric laws, and other emerging U.S. state privacy laws pose increasingly complex compliance challenges and could potentially elevate our compliance costs.

Rewritten

Any failure to comply with these laws and regulations, or an exposure or exfiltration of information covered by such laws and regulations, including, without limitation, in connection with a cybersecurity incident, could [removed: result in significant penalties and legal liability, and increased costs in this area could] have a negative impact on our reputation [removed: and our financial condition, results of operations,] [added: or result in significant penalties] and [removed: cash flow.][added: legal liability.]

Rewritten

For further discussion of our impairment testing, see Note 8 - Goodwill, Identifiable Intangible Assets, and Other Long-Lived Assets [added: of the notes to consolidated financial statements] included in Item 8.

Rewritten

New laws, rules, and regulations, or changes to existing laws or their interpretations, could [added: create added legal and compliance costs and uncertainty for us.]

Rewritten

*Our failure to comply with environmental laws could result in significant liabilities.* Our operations are subject to various laws, including environmental laws and regulations, among which many deal with the handling and disposal of hazardous or universal waste products, polychlorinated [removed: biphenyls (PCBs),] [added: biphenyls,] per- and polyfluoroalkyl [removed: substances (PFAS),] [added: substances,] and fuel storage.

Rewritten

[removed: In addition, new] [added: New] laws and regulations, stricter enforcement of existing laws and regulations, the discovery of previously unknown contamination or leaks, exposure to or the release of materials subsequently identified as hazardous by a governmental authority, the imposition of new clean-up requirements, or the exposure of our employees or other contractors to hazardous materials, could require us to incur significant costs or become the basis for new or increased liabilities that could harm our financial position and results of operations, although certain of these costs might be covered by insurance.

Rewritten

[removed: Legal Proceedings and] [added: See] Note 15 - Commitments and Contingencies of the notes to consolidated financial statements included in Item 8.

Rewritten

In addition, sanctions against foreign persons and entities have increased in recent years, especially [removed: as a result of] [added: in connection with] the war in [added: Ukraine and ongoing trade and diplomatic disputes between] the [removed: Ukraine.][added: U.S. and China.]

Rewritten

*The [removed: departure] [added: departure, loss or incapacitation] of key personnel could disrupt our business.* We depend on the continued efforts of our senior [removed: management.][added: management and other key employees.]

New in FY2024

Although the Federal Reserve Board began to decrease the federal funds rate in 2024 after increases in 2022 and much of 2023, the pace and extent of additional decreases are uncertain.

New in FY2024

Additionally, we rely on third-party vendors and manufacturers to supply much of the materials and equipment necessary for our operations.

New in FY2024

Disruptions, shortages, or delays in the availability of such materials and equipment have and may continue to adversely impact our result of operations, cash flows, and reputation with our customers.

New in FY2024

*Changes in U.S. foreign trade policies, including as a result of the new presidential administration, could lead to the imposition of additional trade barriers and tariffs*.

New in FY2024

We cannot predict the full extent of new, extended, or changed trade policies, including tariffs, that may be made by the current or a future presidential administration or Congress, including whether existing tariff policies will be maintained or modified or if changes in the U.S. trade policy could result in reactions from U.S. trading partners, such as adopting responsive trade policies making it more difficult or costly for us to purchase materials or supplies.

New in FY2024

These changes in U.S. trade policy or in laws and policies governing foreign trade, and any resulting negative sentiments towards the United States as a result of such changes, could have an adverse impact on our business, financial position, results of operations, and liquidity.

In addition, some of our operations, particularly those servicing oil and natural gas refineries, are subject to the risk of accidental release of hazardous materials that have in the past and have the potential to result in injuries or fatalities involving our employees or third parties, property damage, or environmental contamination.

New in FY2024

If our personnel cause or are alleged to have caused any such release, it may result in claims for indemnification under our contracts with customers, claims from third-parties or local communities impacted by such release, or investigations or regulatory action by federal, state or local environmental, occupational, health and safety or other authorities.

New in FY2024

These risks could result in a material adverse effect on our business, operating results, financial position, and cash flows, and in some cases, on our reputation or our ability to obtain projects from customers.

Our workforce and operations were impacted by the COVID-19 pandemic.

Dropped from FY2023

For example, we experienced disruptions that impacted our ability to perform our work.

Dropped from FY2023

Such impacts included, but were not limited to, access restrictions and temporary job site shutdowns, reduced labor efficiency resulting from adherence to physical distancing, quarantine, and isolation requirements due to illness or exposure to an infected person, and other enhanced safety protocols mandated at the majority of our worksite locations, and the deferral of maintenance and service projects by our customers.

Dropped from FY2023

The extent to which another epidemic, pandemic or public health emergency could impact our business and results of operations in the future remains highly uncertain and will be affected by a number of factors, which could have a material adverse effect on our business, financial condition, results of operations, and/or stock price.

Dropped from FY2023

Additionally, public health emergencies may result in more of our employees accessing our systems remotely as a result of potential business or facility closures or reduced or staggered in-person attendance in response to such emergencies.

New in FY2024

Revenues for the year ended December 31, 2024 included incremental acquisition contribution of approximately $251.5 million.

New in FY2024

Operating income for the year ended December 31, 2024 included incremental acquisition contribution of $13.4 million, net of amortization expense attributable to identifiable intangible assets of $15.3 million.

New in FY2024

While the majority of the increase in our net income and diluted earnings per share was a result of the increased operating income referenced above, these amounts additionally benefited from greater interest income and a reduction in interest expense in 2024.

New in FY2024

For further discussion regarding our acquisitions, refer to Note 4 - Acquisitions of Businesses of the notes to consolidated financial statements included in Item 8.

New in FY2024

During 2024, we acquired seven companies for upfront consideration of $231.1 million, inclusive of customary working capital adjustments.

New in FY2024

These acquisitions are comprised of: (a) an electrical contractor in the Southeast region of the United States, that has been included in our United States electrical construction and facilities services segment, (b) two companies that have been included within our United States mechanical construction and facilities services segment, including: (i) a leading plumbing services provider in the Southeast region of the United States and (ii) a full service provider of mechanical construction and maintenance services in Central Texas, (c) three companies that have been included in our United States building services segment, including: (i) a provider of building automation and controls solutions in the Northeast region of the United States, (ii) a mechanical services company in the Western region of the United States, and (iii) a mechanical services company in the Eastern region of the United States, and (d) an instrumentation and electrical contractor, that has been included in our United States industrial services segment, which provides electrical, automation, digital integration, and fabrication services to various energy sector and process equipment customers.

Additionally, revenues for 2024 included incremental acquisition contribution of approximately $251.5 million.

New in FY2024

This segment’s results for 2024 included $2.7 million of incremental acquisition revenues.

New in FY2024

Excluding the impact of acquisitions, the increase in this segment’s revenues was primarily a result of growth within the network and communications market sector, predominantly due to data center construction projects.

New in FY2024

Increased demand for cloud computing and data storage, driven in part by the emergence of artificial intelligence, has resulted in a greater number of project opportunities for us in several of the geographies in which we operate.

New in FY2024

In addition, this segment benefited from revenue growth within a number of the other market sectors we serve, such as: (a) the high-tech manufacturing market sector, inclusive of construction projects for customers engaged in the design and manufacturing of semiconductors, (b) the manufacturing and industrial market sector, driven by increased activity with various energy sector customers, (c) the transportation market sector, due to certain infrastructure projects currently underway, and (d) the institutional market sector, given increased project revenues from certain schools and universities.

New in FY2024

These increases were partially offset by a reduction in revenues within the commercial market sector due in part to reduced demand across the commercial real estate industry.

New in FY2024

Excluding the impact of acquisitions, the increase in this segment’s revenues was attributable to revenue growth within the majority of the market sectors in which we operate, as well as greater levels of service work.

New in FY2024

Partially offsetting these increases was a reduction in revenues within the commercial market sector, largely as a result of the completion of various warehouse and distribution projects, that were active in 2023.

New in FY2024

Excluding incremental acquisition contribution of $31.0 million, this segment’s revenues decreased by $36.3 million as the strength of its mechanical services division was more than offset by revenue declines within its commercial site-based services and government site-based services divisions due to the loss of certain facilities maintenance contracts not renewed pursuant to rebid.

New in FY2024

This segment’s results included $45.3 million of incremental revenues from an acquired company.

New in FY2024

Excluding such acquisition contribution, the increase in this segment’s revenues resulted from greater demand, including turnarounds of a larger size and scope growth on certain projects, in its field services division.

Operating income for 2024 included incremental acquisition contribution of $13.4 million net of amortization expense attributable to identifiable intangible assets of $15.3 million.

New in FY2024

While the most significant increase in gross profit was experienced within the network and communications market sector, this segment additionally benefited from greater gross profit recognized on projects within the manufacturing and industrial, transportation, institutional, and high-tech manufacturing market sectors.

New in FY2024

This segment’s operating income for 2024 included incremental acquisition contribution of $14.4 million net of amortization expense attributable to identifiable intangible assets of $10.3 million.

New in FY2024

While the most significant increases in gross profit were seen within the above referenced market sectors, this segment also experienced increases in gross profit across all of the other market sectors in which we operate, with notable increases generated within institutional, manufacturing and industrial, and commercial.

New in FY2024

Increased gross profit from this segment’s mechanical services division, due primarily to greater profitability across its portfolio of HVAC and building automation and controls projects and retrofits, was partially offset by reductions in gross profit from its commercial site-based services and government site-based services divisions, given the loss of certain facilities maintenance contracts not renewed pursuant to rebid.

New in FY2024

In addition, operating income and operating margin for the year ended December 31, 2024 were negatively impacted by an $11.0 million reserve recorded during the first quarter for a specific customer bankruptcy within this segment’s commercial site-based services division.

New in FY2024

Such reserve negatively impacted the operating margin of this segment for 2024 by approximately 30 basis points.

New in FY2024

The increase in operating margin of this segment was attributable to the increased gross profit margin within the shop services division.

New in FY2024

The decrease in operating income and operating margin was due to a decline in gross profit and gross profit margin.

New in FY2024

In addition to the impact of lower facilities maintenance revenues, gross profit and gross profit margin were negatively affected by a less favorable mix of work when compared to the prior year, which included a greater number of higher margin projects.

New in FY2024

The increase in corporate expenses was primarily due to: (a) greater employment compensation and related costs, including salaries and benefits, incentive compensation, and share-based compensation, (b) certain severance expenses which were recorded during the first quarter of the year, and (c) higher computer hardware and software costs, due to various information technology and cybersecurity initiatives currently in process.

[Table of Contents](#iff155233dd944a23b1f9264cd2aff3a6_7)

New in FY2024

The year-over-year decrease in interest expense was a result of the repayment, in December of 2023, of all previously outstanding direct borrowings under our credit facility.

Dropped from FY2023

Our reportable segments and related disclosures reflect certain reclassifications of prior year amounts from our United States mechanical construction and facilities services segment to our United States building services segment due to changes in our internal reporting structure aimed at realigning our service offerings.

Market Update

Dropped from FY2023

Our business and end markets remained resilient despite the impact of uncertain global economic conditions, including supply chain, production, and other logistical issues, an inflationary cost environment, elevated interest rates, and skilled labor shortages in certain regions.

Dropped from FY2023

The continued strength in demand for our services is reflected in our results of operations for 2023, during which we experienced an increase in both revenue and operating income when compared to 2022.

Dropped from FY2023

As evidenced by the growth in our remaining performance obligations, which increased to $8.85 billion at December 31, 2023, from $7.46 billion at December 31, 2022, we anticipate a similar level of demand for our services in the near term, provided that the business environment does not significantly deteriorate.

Dropped from FY2023

Although improved from 2022, we continued to experience pressures in our supply chain, which resulted in material and equipment lead times significantly in excess of normal levels.

Dropped from FY2023

Delays in critical material and equipment deliveries additionally resulted in us funding purchases at earlier stages of project progression, or in advance of project commencement.

Dropped from FY2023

While we generally strive to negotiate advanced payments or billing terms with our customers that allow us to invoice for these amounts, such purchases may apply pressure on our working capital requirements in future periods.

Dropped from FY2023

Although we experienced a reduction in commodity prices when compared to 2022, and current economic indicators suggest that inflation is slowing, there continues to be volatility in the price of fuel, certain materials, and other commodities used in our operations.

Dropped from FY2023

Further, in an effort to mitigate inflation, the Federal Reserve Board increased the federal funds rate throughout 2022 and into 2023.

Dropped from FY2023

Our management teams continue to adapt to the challenges of the current operating environment in order to manage our business more effectively through diligent contract negotiations, enhanced labor planning and project scheduling, and increased supplier engagement.

Dropped from FY2023

As contractually permitted, and in order to combat inflationary pressures, we have and will continue to seek increases in pricing to the extent we experience increases in our costs.

Dropped from FY2023

While we believe the actions we have taken continue to be effective, as evidenced in part by our operating performance and operating cash flow in 2023, the impact of these disruptions continues to evolve and there can be no assurance that our actions will serve to mitigate such impacts in future periods.

Dropped from FY2023

Further, while we believe our remaining performance obligations are firm, and we have not experienced any material project cancellations to date, prolonged delays in the receipt of critical equipment could impact our ability to convert such remaining performance obligations to revenues in the near term or result in our customers seeking to delay or terminate existing or pending agreements.

Dropped from FY2023

Lastly, the current interest rate environment may cause a decline in capital or maintenance spending of our customers or prospective customers, particularly as it pertains to short duration project work.

Dropped from FY2023

Any of these events could result in reduced demand for our services or affect our ability to collect payment, and therefore, have a material adverse effect on our business, financial condition, and/or results of operations.

Companies acquired in 2023 and 2022 generated incremental revenues of $107.1 million in 2023.

Dropped from FY2023

Excluding the impact of acquisitions, revenues of this segment increased by $262.1 million as a result of an increase in revenues within many of the market sectors in which we operate, most notably including: (a) the network and communications market sector, predominantly due to our data center projects, (b) the manufacturing and industrial market sector, from contracts with our energy sector customers, including those for renewable energy projects, (c) the healthcare market sector, as a result of greater activity throughout certain of the regions in which we operate, (d) the hospitality and entertainment market sector, given an increase in projects within the Western region of the United States, and (e) the high-tech manufacturing market sector, due to an increase in projects for various biotech, life-sciences, and pharmaceutical customers as well as certain semiconductor manufacturers.

Dropped from FY2023

Partially offsetting these increases were modest revenue declines from the commercial market sector and the institutional market sector as well as a reduction in short duration project volume.

Dropped from FY2023

In addition to increased revenues from its mechanical services division, this segment also experienced revenue growth from its commercial site-based services and government site-based services divisions, due to the award of facilities maintenance contracts with new customers as well as scope or site expansion and increased project work with existing customers.

Dropped from FY2023

The results of operations of this segment continued to improve at a modest pace, as evidenced by the revenue growth within both this segment’s field services and shop services divisions during 2023.

Dropped from FY2023

In addition to steady demand for maintenance and turnaround projects, during 2023, we experienced increased levels of capital spending by our customers, in the form of greater new build heat exchanger orders and the award of certain renewable fuel projects.

Dropped from FY2023

Excluding the impact of foreign exchange rate movements, this segment’s revenues decreased during 2023 as a result of: (a) the loss of certain facilities maintenance contracts not renewed pursuant to rebid, and (b) a reduction in project activity, notably within the network and communications market sector.

Dropped from FY2023

In addition to these increases in employment costs, our SG&A for 2023 included incremental: (a) computer hardware and software costs, as a result of various information technology and cybersecurity initiatives currently in process, (b) travel and entertainment expenses, and (c) rent and other occupancy costs driven by: (i) the expansion or addition of certain fabrication facilities, which support our operations, and (ii) the impact of inflation on the real estate market.

Dropped from FY2023

Our performance in 2023 established new annual records for the Company with respect to operating income and operating margin.

Dropped from FY2023

As described in more detail below, improvements in profitability were a result of: (a) better project execution, (b) a more favorable mix of work, (c) the successful close-out of certain projects within our United States construction segments, and (d) the impact in 2022 of certain supply chain disruptions and delays, which were greater than those experienced in 2023, and which, in the prior year, led to: (i) reduced labor productivity and efficiency, (ii) the under-absorption of labor costs in instances where projects were delayed pending the receipt of materials, or (iii) material and commodity price escalations.

Dropped from FY2023

The largest increases in gross profit and gross profit margin were recognized within the network and communications market sector, the commercial market sector, and the healthcare market sector.

Dropped from FY2023

Although we continue to experience supply chain disruptions and delays, which are impacting project delivery in various ways, market conditions surrounding equipment availability steadily improved over the last year and our management teams continued to adapt to this environment.

Dropped from FY2023

Such developments led to improved job-site and labor productivity as well as more normalized project sequencing, resulting in fewer project write-downs when compared to the prior year.

Dropped from FY2023

While these reductions in estimated project profitability negatively affected operating margin of this segment by 40 basis points for 2023, the impact in 2022 was 140 basis points.

Dropped from FY2023

Partially offsetting the year-over-year improvements in gross profit and gross profit margin were increased selling, general and administrative expenses and SG&A margin, largely as a result of greater incentive compensation expense recognized by several operating subsidiaries of this segment given improvements in profitability year-over-year.

Dropped from FY2023

Operating income and operating margin of this segment were also favorably impacted as a result of the successful close-out of certain projects during 2023 and improved productivity, due in part to investments in building information modeling, prefabrication, and digital tools.

Dropped from FY2023

Similar to our United States electrical construction and facilities services segment, the results of this segment in the prior year were negatively impacted by external market conditions, which manifested themselves through price escalations, particularly for materials and commodities, such as copper and steel, that are used in our mechanical and fire protection operations.

Dropped from FY2023

Although there remains volatility in the pricing of these commodities, more favorable pricing year-over-year has resulted in improved profitability of this segment during 2023.

Dropped from FY2023

Increased gross profit and gross profit margin of this segment were partially offset by higher selling, general and administrative expenses and a slight increase in SG&A margin, given greater: (a) incentive compensation expense, due to improved operating results for certain of the operating subsidiaries within this segment, and (b) salaries and related employment costs, largely as a result of additional headcount to support current and anticipated organic revenue growth.

Dropped from FY2023

The $36.4 million increase in operating income and the 60 basis point increase in operating margin for 2023 was almost entirely attributable to this segment’s mechanical services division, as a result of greater gross profit and gross profit margin across all of its service lines, with the largest incremental contribution from projects and retrofits as well as building automation and controls.

Dropped from FY2023

These improvements were due in part to favorable project execution, greater absorption of indirect costs, and favorable contractual terms.

Dropped from FY2023

Operating performance of this segment continues to improve steadily and we are beginning to experience better pricing, most notably within the shop services division.

The Financial Accounting Standards Board (the “FASB”) has issued an Accounting Standards Update (“ASU”), which provides temporary optional expedients and exceptions to existing U.S. GAAP.

Dropped from FY2023

This guidance is aimed at easing the financial reporting burdens related to reference rate reform, including the market transition from the London interbank offered rate (“LIBOR”), or other interbank offered rates, to alternative reference rates.

Dropped from FY2023

Such accounting pronouncement, as amended, allows entities to account for and present certain contract modifications, which occur before December 31, 2024 and result from the transition to an alternative reference rate, as an event that does not require remeasurement at the modification date or reassessment of a previous accounting determination.

Dropped from FY2023

In order to utilize such guidance, an entity must first conclude that the modified terms directly replace or have the potential to replace an eligible reference rate due to reference rate reform, and that any contemporaneous changes to other terms that change, or have the potential to change, the amount or timing of contractual cash flows are related to the replacement of a reference rate.

Dropped from FY2023

During the second quarter of 2023, we amended our then existing credit agreement to change the reference rate from LIBOR to an interest rate based on the secured overnight financing rate, as administered by the Federal Reserve Bank of New York (“SOFR”).

Dropped from FY2023

As such amendment was within the scope of the aforementioned guidance, we adopted this accounting pronouncement and utilized the optional expedients referenced above.

We are not exposed to any other material contracts that reference LIBOR.
