In the fourth quarter of 2024, we will begin accounting for our investment in NuScale using the fair value option for equity method investments, under which we will measure our investment at fair value on a recurring basis using the prevailing price of NuScale's stock on our balance sheet dates. The fair value of our investment in NuScale is subject to the fluctuations of NuScale's stock price, which may subject our consolidated earnings to volatility. The price of NuScale's stock has experienced significant volatility since it commenced trading in May 2022, and the volatility may continue in the future in response to many factors, including factors beyond the control of NuScale. As a result of the recurring fair value measurements, we may recognize non-cash gains or losses in future periods, some of which which could be material.

Because our projects are often technically complex, with multiple phases occurring over several years, we incur risks in our project execution activities. These risks could result in project delays, cost overruns or other problems and can include the following: - Evolving estimates related to productivity, scheduling estimates or future economic conditions, including with respect to the impacts of inflation on lump-sum contracts;- Unanticipated technical problems, including design or engineering issues;- Inaccurate representations of site conditions and unanticipated changes in the project execution plan;- Project modifications creating unanticipated costs or delays and failure to properly manage project modifications;- Inability to achieve guaranteed performance or quality standards with regard to engineering, construction or project management obligations;- Insufficient or inadequate project execution tools and systems needed to record, track, forecast and control cost and schedule;- Reliance on historical cost and/or execution data that is not representative of current economic and/or execution conditions;- Failure to accurately estimate the timing and cost of projects, including due to inflation, supply chain disruption, rising construction costs or unforeseen increases in the cost of labor;- Unanticipated increases in the cost of raw materials, components or equipment, including due to inflation or the imposition of import tariffs;- Failure to properly make judgments in accordance with applicable professional standards, including engineering standards;- Failure to properly assess and update appropriate risk mitigation strategies and measures;- Poor performance of our clients, partners, subcontractors, suppliers or other third parties;- Delays or productivity issues caused by weather; and - Changes in local laws or difficulties or delays in obtaining permits, rights of way or approvals. These and other risks have in the past, and may in the future, result in our failure to achieve contractual cost or schedule commitments, safety performance, overall client satisfaction or other performance criteria. As a result, we may receive lower fees or lose our ability to earn incentive fees. In other cases, our fee will not change but we will have to continue to perform work without additional fees until the performance criteria is achieved. We may also incur liquidated damages if we fail to complete a project on schedule. In addition, if we fail to meet guaranteed performance or quality standards, we may be held responsible under the guarantee or warranty provisions of our contract for cost impact to the client, generally in the form of contractually agreed-upon liquidated damages or an obligation to re-perform work. To the extent these events occur, the total cost to the project (including any liquidated damages) could be material and could, in some circumstances, equal or exceed the full value of the contract. In such events, our financial condition or results of operations could be materially and negatively impacted. In circumstances where the contract is lump-sum or the revenue is otherwise fixed, we bear significant risk for delays and cost overruns. Reimbursable contract types, such as those that include negotiated hourly billing rates, may restrict the kinds or amounts of costs that are reimbursable, therefore exposing us to the risk that we may incur certain costs in executing these contracts that are above our estimates and not recoverable from our clients.

The awarding and timing of projects is unpredictable and driven by our clients. Awards, including expansions of existing projects, often involve complex and lengthy negotiations and competitive bidding processes. These processes can be impacted by a wide variety of factors including a client's decision to not proceed with the development of a project, governmental approvals, financing contingencies, oil prices, environmental conditions and overall market and economic conditions. We may not win contracts that we have bid on due to price, a client's perception of our ability to perform and/or perceived technology advantages held by others. Many of our competitors may be more inclined to take greater risks or include terms and conditions that we might not deem acceptable, especially when the markets for the services we typically offer are relatively soft. Because a significant portion of our revenue is generated from large projects, our results can fluctuate depending on whether and when large project awards occur and the commencement and progress of work under large contracts already awarded. As a result, we are subject to the risk of losing new awards to competitors or the risk that revenue may not be derived from awarded projects as quickly as anticipated. Additionally, uncertain economic and political conditions may make it difficult for our clients, our vendors and us to accurately forecast and plan future business activities. For example, changes to U.S. policies related to global trade and tariffs in recent years, and responsive changes in policy by foreign jurisdictions, have resulted in uncertainty surrounding the future of the global economy as well as retaliatory trade measures implemented by other countries. We cannot predict the outcome of changing trade policies or other unanticipated economic or political conditions, nor can we predict the timing, strength or duration of any worldwide economic recovery or downturn or in the markets that we serve.

We have a significant portfolio of government contracts, including those that we have in place with the DOE and U.S. Department of Defense. U.S. government contracts are subject to various uncertainties, restrictions and regulations, including oversight audits by government agencies and profit and cost controls, which could result in withholding or delay of payments to us. U.S. government contracts are also subject to uncertainties associated with congressional funding, including the potential impacts of budget deficits, government shutdowns and federal sequestration. A significant reduction in federal government spending or a change in budgetary priorities could reduce demand for our services, cancel or delay federal projects, and result in the closure of federal facilities and significant personnel reductions. Changes in U.S. government priorities, which can occur due to policy changes or economic changes, could adversely impact our revenues. The U.S. government is under no obligation to maintain program funding at any specific level, and funds for a program may even be eliminated. Our U.S. government clients may terminate or decide not to renew our contracts with little or no prior notice. In addition, U.S. government contracts are subject to specific regulations such as the Federal Acquisition Regulation ("FAR"), the Truth in Negotiations Act, the Cost Accounting Standards ("CAS"), the Service Contract Act and Department of Defense security regulations. Failure to comply with any of these regulations and other government requirements may result in contract price adjustments, financial penalties or contract termination. Our U.S. government contracts are also subject to audits, cost reviews and investigations by U.S. government oversight agencies such as the U.S. Defense Contract Audit Agency (the "DCAA"). The DCAA reviews the adequacy of, and our compliance with, our internal controls and policies (including our labor, billing, accounting, purchasing, estimating, compensation and management information systems). The DCAA also has the ability to review how we have accounted for costs under the FAR and CAS. The DCAA presents its findings to the Defense Contract Management Agency ("DCMA"). Should the DCMA determine that we have not complied with the terms of our contract and applicable statutes and regulations, or if they believe that we have engaged in inappropriate accounting or other activities, payments to us may be disallowed or we could be required to refund previously collected payments. Additionally, we may be subject to criminal and civil penalties, suspension or debarment from future government contracts, and qui tam litigation brought by private individuals on behalf of the U.S. government under the False Claims Act, which could include claims for treble damages. These suits may remain under seal (and hence, be unknown to us) for some time while the government decides whether to intervene on behalf of the qui tam plaintiff. Furthermore, if we have significant disagreements with our government clients concerning costs incurred, negative publicity could arise, which could adversely affect our industry reputation and our ability to compete for new contracts in the government arena or otherwise. Most U.S. government contracts are awarded through a rigorous competitive process. The U.S. government has increasingly relied upon multiple-year contracts with pre-established terms and conditions that generally require those contractors that have been previously awarded the contract to engage in an additional competitive bidding process for each task order issued under the contract. Such processes require successful contractors to anticipate requirements and develop rapid-response bid and proposal teams as well as dedicated supplier relationships and delivery systems to react to these needs. We face rigorous competition and significant pricing pressures in order to win these task orders. If we are not successful in containing costs or able to timely respond to government requests, we may not win additional awards. Moreover, even if we are qualified to work on a government contract, we may be impacted in our pursuit of work by government policies designed to protect small businesses and under- represented minority contractors. Many of our U.S. government contracts require security clearances. Depending upon the level of clearance required, security clearances can be difficult and time-consuming to obtain. If we or our employees are unable to obtain or retain necessary security clearances, we may not be able to win new business, and our existing government clients could terminate their contracts with us or decide not to renew them.

We often work on complex projects, frequently in geographically remote or high-risk locations that are subject to political, social or economic risks, or war or civil unrest. In those locations where we have employees or operations, we may expend significant efforts and incur substantial security costs to maintain safety. In addition, our project sites can place our employees and others near large equipment, dangerous processes or substances or highly regulated materials, and in challenging environments. Safety is a primary focus of our business and is critical to our reputation and performance. Many of our clients require that we meet certain safety criteria to be eligible to bid on contracts, and some of our contract fees or profits are subject to satisfying safety criteria. Unsafe work conditions also have the potential of increasing employee turnover, increasing project costs and raising our operating costs. If we fail to implement appropriate safety procedures and/or if our procedures fail, our employees or others may suffer injuries or loss of life, the completion of a project could be delayed and we could experience investigations or litigation. Although we have a safety function to implement effective health, safety and environmental procedures throughout our company, the failure to comply with such procedures, client contracts or applicable regulations could subject us to losses and liability. Despite these activities we cannot guarantee the safety of our personnel, nor can we guarantee our work, equipment or supplies will be free from damage.
