Item 1A. Risk Factors.

Please refer to Item 1A- Risk Factors in our 2024 Form 10-K, which is incorporated herein by reference, for a discussion of some of the factors that have affected our business, financial condition, and results of operations in the past and which could affect us in the future. There have been no material changes to those risk factors, except for the information disclosed elsewhere in this Quarterly Report on Form 10-Q that provides factual updates to those risk factors and the inclusion of the additional risk factors set forth below. Before making an investment decision with respect to our common stock, you should carefully consider those risk factors, as well as the financial and business disclosures contained in this Quarterly Report on Form 10-Q and our other current and periodic reports filed with the SEC.

Recent international trade issues, including tariffs and counter tariffs, if continued, may have a negative impact on our business generally.

Recently, there have been notable developments in international trade from the imposition of tariffs and counter tariffs in the United States, and in other countries in which we or our customers and suppliers operate. Increases in protectionist measures such as tariffs or import or export licensing requirements, whether imposed by the United States or such other countries, may adversely impact our business by causing a slowdown in global trade and a decrease in government or corporate spending.

These measures may also have the effect of heightening many of the other risks applicable to our business, including risks relating to:

• the impact of inflation and rising interest rates and/or construction costs, particularly on any fixed-price contract, which we may not be able to fully mitigate,

• our failure to meet performance requirements or contractual schedules, including as a result of supply chain disruptions,

• a reduction in the amount of available governmental funding,

• our international operations, including risks of facing backlash from potential customers as a result of being headquartered in the United States, and

• our indebtedness and credit markets.

While tariffs on goods and other trade measures have not yet had a significant impact on our business or results of operations, we are monitoring and evaluating any potential impacts that the imposition of tariffs and other trade measures may have on our business, and considering ways in which we, or our clients, may mitigate the potential impact of such tariffs and other trade measures. There is no assurance that we will be successful in mitigating such impacts. Additionally, we cannot fully predict the further developments that could have a material adverse impact on our business, financial condition and results of operations.
