Risk Assessment Framework

Strategic & Market Risks

Market Dynamics:

• U.S. Federal Government Dependency: 81% of revenues from U.S. federal government contracts, subject to termination for convenience, competitive procurement, security clearance requirements, and small business set-aside programs. Negative publicity or performance issues could harm reputation and contract awards.
• Government Budget & Spending: Delays in budget approval, continuing resolutions, government shutdowns, or declines/shifts in federal spending priorities (e.g., defense, national security, intelligence, homeland security) could adversely affect revenue, cash flow, and operating results.
• Competition: Intense competition from well-established and specialized companies, potentially leading to market share loss, reduced profitability, and increased pricing pressure.
• Contract Awards Timing: Revenues depend on new contract awards; delays or cancellations can impact projected results and workforce utilization, leading to increased costs.
• Economic Downturns: Demand for services is impacted by economic downturns, reductions in government or private spending, and political uncertainty, potentially reducing capital expenditures and increasing pricing pressure.

Operational & Execution Risks

Supply Chain Vulnerabilities:

• Cost Overruns: Fixed-price contracts (24% of FY25 revenues) expose the Company to risks of cost overruns due to inaccurate estimates, unanticipated technical problems, delays, changes in costs of equipment/materials, or subcontractor failures.
• Performance Requirements: Failure to meet performance requirements or contractual schedules can result in penalties, liquidity impacts, and potential liability claims.
• Safety & Environmental Risks: Work sites involve inherent safety and environmental risks (e.g., large equipment, hazardous materials, nuclear waste), potentially leading to injuries, disabilities, loss of life, significant financial losses, reputational harm, and civil/criminal liabilities.
• Employee/Agent Misconduct: Risk of misconduct, fraud, or non-compliance with laws/regulations (e.g., procurement, classified information, anti-bribery), potentially leading to fines, contract cancellation, loss of security clearance, and debarment.
• Cybersecurity & IT Interruptions: Threats from unauthorized access, viruses, ransomware, and system failures could impact operations, compromise sensitive information, and lead to financial losses and reputational harm.
• Nuclear Services Indemnification: Inadequate indemnification for nuclear services or delays due to extensive regulatory processes/socio-political opposition could adversely affect business.

Financial & Regulatory Risks

Market & Financial Risks:

• Inflation & Interest Rates: Continuing elevated inflation, rising or high interest rates could reduce demand for services and decrease profit on fixed-price contracts. Variable rate debt (Term Loan, Revolver) exposes the Company to interest rate risk.
• Indebtedness: Significant amount of indebtedness ($3,943 million as of October 3, 2025) could affect financial condition, reduce business flexibility, and require a substantial portion of cash flow for debt service.
• Goodwill & Intangible Assets Impairment: $5.7 billion of goodwill (49.8% of total assets) is subject to annual impairment testing, and a significant charge could materially impact financial position.
• Litigation & Claims: Exposure to significant monetary damages or criminal violations from liabilities, noncompliance with regulations, professional judgments, or contractual disputes. Insurance may not provide adequate coverage.
• Taxation: Changes in domestic and foreign tax laws, statutory tax rates, or unanticipated outcomes from tax audits could adversely affect profitability.
• Cash Concentration: Cash balances at financial institutions may exceed federally insured limits, posing a risk of loss if institutions fail.

Regulatory & Compliance Risks:

• Government Contractor Regulations: Subject to extensive procurement laws (FAR, Truthful Cost or Pricing Data Act, CAS, FCPA, ITAR, FCA), with non-compliance leading to penalties, contract termination, or debarment.
• Data Privacy & Security: Complex and evolving laws (GDPR, NIST SP 800-171, CMMC) impose compliance challenges, potential investigations, monetary penalties, and reputational harm.
• Sustainability Regulations: Increased scrutiny and changing expectations regarding sustainability practices may impose additional costs or risks, impacting reputation and ability to attract business/talent.

Geopolitical & External Risks

Geopolitical Exposure:

• International Operations Risks: Exposure to political developments, weak foreign economies, staffing difficulties, changes in government policies, non-compliance with anti-corruption/export control laws, lack of legal enforcement, expropriation, trade restrictions, and acts of war/terrorism in over 70 countries.
• Global Tariffs: Uncertainty over global tariffs and trade policies could increase material costs, disrupt deliveries, and impact planning.
• Climate Change: Climate-related weather issues (storms, floods, wildfires) could damage equipment/infrastructure, disrupt operations, cause delays, and increase costs. Market or regulatory responses to climate change could also impact demand for services or increase compliance costs.

Revenues may be unfavorably impacted in summer and holiday seasons due to more holidays and higher vacation utilization.
• Economic Sensitivity: Demand for services is subject to significant fluctuations due to economic conditions and changes in customer spending, particularly during periods of economic or political uncertainty.
• Industry Cycles: The Company's diverse portfolio aims to position it in areas of government funding tailwinds while mitigating risk during periods of transition.

Tax Strategy & Considerations

Tax Profile (FY25):

• Effective Tax Rate: 48.7% (compared to 32.5% in FY24).
• Rate Drivers: Primarily due to the recognition of a valuation allowance against a deferred tax asset related to disallowed interest expense, release of a valuation allowance related to domestic capital losses, and the tax effect of the Rapid Solutions divestiture.
• Geographic Tax Planning: International tax structure and transfer pricing are not explicitly detailed, but the Company is subject to taxation in multiple jurisdictions.
• Tax Reform Impact: The One Big, Beautiful Bill Act ("OBBBA") enacted on July 4, 2025, permanently restored EBITDA as the basis for computing business interest expense limitations and allowed immediate expensing of research expenditures, impacting the FY25 income tax provision.

Insurance & Risk Transfer

Risk Management Framework:

• Insurance Coverage: The Company has adopted a range of insurance, risk management, and risk avoidance programs designed to reduce potential liabilities. However, liabilities may exceed insurance limits or not be covered due to exclusions.
• Risk Transfer Mechanisms: Indemnification from customers or subcontractors may be sought, but may not always be available or sufficient. The Price-Anderson Nuclear Industries Indemnity Act ("PAA") provides certain protections and indemnification for nuclear services in the U.S., with similar protections in other jurisdictions through treaties, domestic laws, and contractual indemnifications.
