What Changed

Risk factors · Feb 28, 2025 → Feb 26, 2026

52 added · 57 removed between the two most recent 10-Ks. The risks a company starts — or stops — disclosing are often the story.

Newly disclosed

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.
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.
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.
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.
While we seek to minimize these conflicts of interest through the terms set in the agreements for these investments, as well as processes in place to manage these relationships, any failure to adequately manage a potential conflict of interest, or the perception of a conflict, could damage our relationships with investment partners, result in litigation, or harm our professional reputation.
We have recorded impairment losses in the past, and any future impairments to goodwill, other intangible assets, or long-lived assets could materially and adversely affect our results of operations and financial condition.
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.
Impairment testing of goodwill involves qualitative assessments and quantitative tests to determine the fair value of our reporting units and is dependent upon estimates and assumptions.
If we determine the fair value of a reporting unit with goodwill is less than its carrying value as a result of an annual or interim test, an impairment loss is recognized.
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.
GAAP, we are required to test goodwill for possible impairment annually, and whenever events occur that indicate impairment may exist.
Although the Federal Reserve lowered short-term interest rates in 2025, interest rates, particularly long-term rates, remain elevated.

No longer disclosed

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.
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.
For example, if new regulations were adopted regulating greenhouse gas emissions, or if we were otherwise required to undertake carbon emission reduction efforts, we could experience a significant increase in environmental compliance costs considering our large fleet and the amount of construction machinery we own.
These factors, as well as advances in artificial intelligence and government policies, including spending policies, related to artificial intelligence, could have an adverse effect on our customers, reduce demand for our services and adversely affect our results of operations, cash flows and liquidity.
GAAP, we are required to test goodwill and intangible assets carried in our consolidated balance sheets for possible impairment on an annual basis based upon a fair value approach and whenever events occur that indicate impairment could exist.
These events and circumstances could adversely affect the estimated fair values of the related reporting units and result in an impairment of the recorded balances of goodwill or intangible assets, which could materially and adversely affect our business, results of operations and financial condition.
If we do not adapt to or comply with stakeholder expectations and standards on ESG matters as they continue to evolve, or if we are perceived to have not responded appropriately or quickly enough to growing concern for ESG and sustainability issues, regardless of whether there is a regulatory or legal requirement to do so, it could result in loss of business and an inability to attract and retain customers and talented personnel, or we could suffer reputational damage and/or increased risk of potential litigation, all of which could adversely affect our business, results of operations and financial condition, and could result in an increase in our cost of capital and/or a decline in the price per share of our common stock.
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”).
In addition, although the Federal Reserve has periodically lowered short-term interest rates since September 2024, interest rates, particularly long-term rates, remain elevated along with levels of inflation, and we have been subject to, and may continue to be subject to, the general effect of such inflationary market pressures on our business, particularly with respect to interest expense and labor, materials and fuel costs.
Failures or delays in achieving our strategies or expectations, whether actual or perceived, could adversely affect our business, operations and reputation, and could increase our risk of litigation.
New regulations requiring us to acquire different equipment or change processes could result in an impairment of our current fleet or other equipment assets.
In January 2025, President Trump announced a temporary pause on new and renewed federal permits and leasing for wind turbine projects, with no end date to such pause specified.
