Factors considered by management in determining the reporting units for which quantitative assessments were performed included the effects of current or expected changes in market conditions on the future business outlook, including, as described above, the potential future effects of macroeconomic trends and events, industry, market and regulatory factors, climate-related or other factors, rates of success on new project awards and levels of operating activity.
Added
If, after performing a qualitative assessment, we determine that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, we then perform a quantitative impairment test for those reporting units.
Removed
Significant assumptions used in testing the reporting units included terminal values based on a terminal growth rate of 3.0%, five to seven years of discounted cash flows prior to the terminal value, including revenue growth and EBITDA margin assumptions, and discount rates ranging from 9.5% to 11.0%.
Added
For the year ended December 31, 2025, we completed our annual impairment test of goodwill as part of which we performed a qualitative assessment of all reporting units and concluded that it was more likely than not that the fair value of each reporting unit was greater than its carrying value.
Removed
Based on the results of the quantitative assessments, the estimated fair values of all of the tested reporting units were determined to substantially exceed their carrying values. A 100 basis point increase in the discount rate would not have resulted in any of the tested reporting units’ carrying values exceeding their fair values.
Added
Accordingly, a quantitative goodwill impairment test was not required for any of our reporting units, and no goodwill impairment was recognized in 2025.

The details of these changes have not yet emerged, but may include reducing the corporate tax rate for domestic oil and gas production, repealing green energy tax credits and extending certain provisions of the Tax Cuts and Jobs Act of 2017 (“TCJA”).
Added
Demand for LNG exports has risen in recent years and North American export capacity is on track to more than double by 2029, according to an October 2025 publication by the U.S. Energy Information Administration.
Removed
In early February 2025, President Trump announced 25% tariffs on imports from Canada (10% tariff in the case of oil) and Mexico, which tariffs were subsequently delayed until early March 2025, a 10% tariff on imports from China (which President Trump subsequently doubled), and a 25% tariff on all steel and aluminum imports into the United States.
Added
At the same time, the U.S. federal administration has eased environmental regulations, including accelerating permitting reviews of natural gas pipelines and lifting prior pauses on LNG export approvals.
Removed
Many political and economic commentators believe that the impacts of extending certain tax benefits pursuant to the TCJA and new tariffs could potentially cause inflationary pressure that could, in turn, contribute to increases in market interest rates and a decrease in U.S. economic growth.
Added
As a result, we expect sustained demand for new pipeline infrastructure to transport LNG to coastal export facilities over the coming years, including interstate and intrastate pipelines connecting producers to key export terminals.
Removed
We cannot predict, however, whether, when, or to what extent these potential changes in law or policy will become effective, nor can we predict the long-term impact of these potential changes on the industries in which we operate.
Added
Further, according to IBISWorld’s April 2025 publication, “Oil & Gas Pipeline Construction in the U.S.”, many mainline gas pipelines in the United States were built more than 60 years ago, increasing the importance of maintaining the aging infrastructure.
Removed
Elimination of, reduction of, or changes to the IIJA, IRA, existing renewable portfolio standards, environmental policies, tax incentives and/or similar programs, including as a result of the change in administration in the United States, could negatively affect demand for our services.
Added
We believe that gas utility distribution spending for replacement and rehabilitation of aging infrastructure will accelerate over the next several years due to regulatory, sustainability and safety concerns. Similarly, we expect that aging pipeline infrastructure will increasingly require replacement lines and pipeline integrity services as our customers look to enhance the safety, productivity and lives of existing infrastructure.
Removed
All of the above factors could result in fewer projects than anticipated or a delay in the timing of these projects, which could negatively affect demand for our services and have a material adverse effect on our results of operations, cash flows and liquidity.
Added
The United States Environmental Protection Agency (“EPA”) has identified significant long-term funding needs for water and sewer infrastructure, which we expect will drive demand across our diverse water service offerings. According to the EPA’s 2022 Clean Watersheds Needs Survey, over $630 billion will be required over 20 years to address wastewater and stormwater infrastructure needs.
Removed
Unfavorable market conditions, including rising or elevated levels of inflation or interest rates, changes to tariffs and/or trade policies affecting macroeconomic conditions, including inflation, as well as the industries we serve and related projects and expenditures, access to capital, material and costs, supply chain disruptions or political, regulatory or market uncertainty, including economic downturns and heightened geopolitical tensions and conflicts, could reduce capital expenditures in the industries we serve or could adversely affect our customers and result in decreased demand for our services.
Added
Similarly, the EPA’s 2023 Drinking Water Infrastructure Needs Survey and Assessment estimates an additional $625 billion will be required for drinking water infrastructure over a 20 year period. These investments are driven by aging infrastructure, emerging contaminants, and the need for climate resilience.
Removed
Demand for our services has been, and will likely continue to be, cyclical in nature and vulnerable to unfavorable market conditions and/or downturns in the economy.
Added
Ongoing decarbonization efforts and carbon emission reduction initiatives are expected to drive demand for carbon capture and sequestration technologies, as well as the use of hydrogen as a clean energy power source.
Removed
Unfavorable market conditions, including rising or elevated levels of inflation and/or interest rates, supply chain disruptions, changes to tariffs or trade policies, affecting macroeconomic conditions, including inflation, as well as the industries we serve and related projects and expenditures, access to capital, material and costs, political, regulatory or market uncertainty or public health matters could have a negative effect on demand for, or the profitability of, our customers’ services, which could have a material adverse effect on our business, financial condition and results of operations.
Added
Pipeline infrastructure is expected to play a key role in the transformation to low carbon energy sources, which could involve constructing new pipelines or repurposing existing infrastructure, and supporting new carbon capture and hydrogen technologies, and we believe that we are well positioned to support these developing market trends in the energy transition.
Removed
During past administrations, increased tariffs were implemented on goods imported into the United States, particularly from China, Canada, and Mexico. As China is a major global exporter of steel, solar panels, and aluminum, the tariffs on these specific imports led to price increases and supply chain issues for materials used in the construction of many of our customers projects.
Added
In light of these trends, we are continuously investing in capabilities to further support carbon capture and hydrogen technology infrastructure. We believe that the above-mentioned trends will support continued levels of future project activity across our diversified pipeline capabilities and that we are well-positioned to benefit from these trends.
Removed
In early February 2025, the Trump administration announced 25% tariffs on imports from Canada (10% tariff in the case of energy exports) and Mexico, which tariffs were subsequently delayed until early March 2025, a 10% tariff on imports from China (which President Trump subsequently doubled), and a 25% tariff on all steel and aluminum imports into the United States.

As of December 31, 2025, 47% of our backlog is estimated to be attributable to amounts under master service or other service agreements, pursuant to which our customers are not contractually committed to purchase a minimum amount of services. Most of these agreements can be canceled on short or no advance notice.
Added
Suppliers, Materials and Working Capital Under many of our contracts, our customers provide the necessary materials and supplies for projects and we are responsible for the installation of, but not the cost or warranty of, those materials.

For example, during the year ended December 31, 2025, the U.S. government announced or imposed a variety of tariff or other trade actions, in response to which many countries have announced retaliatory trade actions, including tariffs on U.S. exports or bans by foreign countries on certain of their exports.
Added
These actions have increased the cost of importing certain construction materials into the U.S., including steel, concrete, copper and solar panels, and have caused disruption and uncertainty to both international trade and supply chains. More recently, on February 20, 2026, the U.S.
Added
Supreme Court ruled that certain trade tariffs imposed by the U.S. federal government under the International Emergency Economic Powers Act (“IEEPA”) were unconstitutional. Following the U.S. Supreme Court’s decision, the U.S. presidential administration announced its intention to invoke other laws to collect tariffs and announced new tariffs on imports from all countries, in addition to any existing non-IEEPA tariffs.
Added
Significant uncertainty remains regarding the status of existing and newly announced tariffs, potential changes or pauses to such tariffs, tariff levels, and whether further additional tariffs or other retaliatory actions may be imposed, modified, or suspended.
Added
We are driven by our commitment to safety and our “Zero Harm” culture to develop and implement safety programs and processes with safety excellence as our goal.
Added
Additional risks and uncertainties not known to us or not described below could also negatively affect our operations. If any of the risks described below or other risks that are unknown to us were to occur, our business, financial condition, results of operations and cash flows could suffer, and/or the trading price of our common stock could decline.
Added
We also may not be able to achieve our goals or expectations. You should carefully consider the risks described below, together with all of the other information in this Form 10-K, including our Cautionary Statement Regarding Forward-Looking Statements above.
Added
Risks Related to the Industries We Serve Changes to laws, governmental regulations and policies, including those pertaining to governmental permitting, tax incentives, government funding programs and spending policies, as well as advances in artificial intelligence, could affect demand for our services, or cause delays or cancellations of projects.
Added
Additionally, demand for construction services depends on industry activity and expenditure levels, which can be affected by a variety of political, macro-economic and market factors. Our inability or failure to adjust to such changes or factors could adversely affect our results of operations, cash flows and liquidity.
Added
The industries we serve are subject to effects of new or changing governmental regulation, including for climate-related matters, governmental permitting, environmental approval processes, stricter enforcement of existing laws and regulations, climate change litigation, and political or social activism, any of which could result in reduced demand for our services, delays in the timing of projects, or cancellations of current or planned future projects.
Added
Many of our customers face stringent regulatory and environmental requirements and permitting processes, including governmental regulations and policies. Most of our communications customers are regulated by the FCC, and our energy customers are regulated by the Federal Energy Regulatory Commission, among others. In addition, our utility customers are regulated by state public utility commissions.
Added
These agencies or governments could change their interpretation of current regulations and/or may impose additional regulations, or change government funding programs or spending policies, including the potential for reduced support for renewable energy projects.
Added
Our customers could be adversely affected by regulatory initiatives or additional requirements, restrictions or legislation imposed by federal, state, local, or foreign governments, including from climate-related matters and/or any related changes in end-customer demand.
Added
The current U.S. administration has implemented various policies and actions that could inhibit wind or renewable energy development activity and, although to date these have been overturned by the courts, or are the subject of ongoing litigation, these policies and actions could create uncertainty that could cause customers to reduce the scope of, delay or cancel renewable energy projects.
Added
Additionally, the current U.S. administration has established initiatives to reform federal government processes and reduce expenditures. Implementation of these initiatives, along with pressures on and uncertainty surrounding the federal budget and budgetary priorities, could adversely affect funding and, as a result, demand for our services.
Added
These factors, as well as potential disruptions related to artificial intelligence in the industries we serve, could have an adverse effect on our customers and reduce demand for our services and adversely affect our results of operations, cash flows and liquidity. 18 We build renewable energy and other infrastructure for which the development may be partially dependent upon federal tax credits, including from the IIJA and IRA, and for renewable infrastructure, existing renewable portfolio standards and other federal or state tax incentives.
Added
The IIJA and IRA provide funding in many of the markets in which we operate. Delays and uncertainty related to the implementation and pace of spending, or to project permitting or other matters under the IIJA, IRA and/or other programs, has caused, and could continue to cause, uncertainty related to the timing of our current and future project work expectations.
Added
Additionally, elimination of, reduction of, or changes to the IIJA, IRA, existing renewable portfolio standards, environmental policies, tax incentives and/or similar programs could negatively affect demand for our services.
Added
In July 2025, OBBBA was signed into law, and while it extended many provisions of the Tax Cuts and Jobs Act of 2017 (“TCJA”), it also accelerated the phaseout of certain clean energy tax credits established under the IRA, including the clean electricity investment and clean energy production credits for solar and wind projects, which may reduce longer term demand for such projects.
Added
We cannot predict, however, whether, when, or to what extent these changes in governmental programs and spending policies will impact the industries in which we operate in the long term.
Added
All of the above factors could result in fewer projects than anticipated or a delay in the timing of these projects, which could negatively affect demand for our services and have a material adverse effect on our results of operations, cash flows and liquidity.
Added
Tariff and trade actions by the United States and other countries could have a material adverse effect on our business, financial condition, and results of operations.
Added
During the year ended December 31, 2025, the U.S. government announced significant trade policy and tariff actions on imports from a broad set of countries, including Canada, Mexico, European Union member states, Japan, Germany and China, in response to which many countries announced retaliatory trade actions, including tariffs on U.S. exports or bans by foreign countries on certain of their exports.
Added
These actions have increased the cost of importing certain construction materials into the U.S., including steel, concrete and solar panels, and have caused disruption and uncertainty to both international trade and supply chains. More recently, on February 20, 2026, the U.S. Supreme Court ruled that certain trade tariffs imposed by the U.S. federal government under the IEEPA were unconstitutional.

The interest we are charged on our variable-rate debt will fluctuate as a result of changes in market interest. Interest on our fixed-rate debt would not change.
