Risk Assessment Framework

Strategic & Market Risks

Market Dynamics: The Company's business is highly dependent on the residential homebuilding and repair and remodeling industries, which are sensitive to economic conditions, interest rates, consumer confidence, and housing affordability. Cyclical market pressures, including fluctuations in building product prices (lumber and lumber sheet goods represented 26% of 2025 net sales), can significantly impact financial performance. A shift in homebuyer demand towards smaller homes could also affect product demand. Growth Strategy Execution: Risks include the inability to successfully implement growth initiatives, such as increasing sales of value-added products, pursuing strategic acquisitions, opening new facilities, and realizing anticipated benefits from digital and technology investments. Acquisition Risks: Strategic acquisitions, while a core growth strategy, involve risks such as integration difficulties, failure to realize anticipated synergies, unforeseen liabilities, and potential dilution from new debt or equity issuance. Customer & Pricing Pressure: The Company faces competitive pricing pressure from large production homebuilders and multi-family builders, which may limit its ability to pass on cost increases. The loss of significant customers or a reduction in their purchasing volumes could materially affect financial health. Supply Chain & Operational Disruptions: Dependence on third-party suppliers for adequate product supply exposes the Company to risks of product shortages or loss of key suppliers. Quarterly revenues, earnings, and cash flows are variable due to factors like commodity price volatility, industry cyclicality, weather, and labor costs/shortages.

Operational & Execution Risks

Information Technology Systems: Operations are highly dependent on IT systems, including a new ERP system currently being implemented. Disruptions, delays, or failures in these systems, or those of third-party service providers, could impair operations, financial reporting, and customer service. Cybersecurity Risks: The Company is exposed to cybersecurity threats, which could lead to data loss, litigation, reputational damage, and increased compliance costs. Human Capital: Failure to attract, hire, train, and retain qualified personnel, including senior management, could adversely impact business execution. Competition for labor has led to higher costs and shortages. Facility Leases: Most facilities are leased under long-term, non-cancelable agreements. Closing or idling facilities would still incur lease obligations, and renewal at acceptable terms is not guaranteed. Legal & Safety Claims: The nature of the business exposes the Company to product liability, product warranty, construction defect, asbestos, vehicle, and workplace safety claims. While insurance is maintained, it may not provide adequate protection against all potential liabilities.

Financial & Regulatory Risks

Indebtedness & Liquidity: As of December 31, 2025, the Company had $4.5 billion in total debt. This level of indebtedness could limit financial flexibility, increase vulnerability to economic conditions, and require a substantial portion of operating cash flow for debt service. Variable rate indebtedness exposes the Company to interest rate risk. Debt instruments contain covenants that restrict business operations. Impairment Charges: A decline in the housing market could necessitate goodwill and/or asset impairment charges, negatively affecting financial results. Regulatory Compliance: Operations are subject to complex and evolving federal, state, and local laws and regulations (e.g., transportation, work safety, employment, tariffs, data privacy, environmental). Non-compliance could result in fines, penalties, and operational restrictions. Tax Laws: Future changes to tax laws, such as the H.R.1 - One Big Beautiful Bill Act, could impact the effective tax rate, corporate taxes, and cash flows. The Act is anticipated to reduce cash tax payments and increase operating cash flows in future years.

Geopolitical & External Risks

Global Economic & Geopolitical Instability: Unstable global economic conditions and geopolitical conflicts (e.g., in Ukraine, Venezuela, the Middle East) can adversely affect the business through impacts on commodity and energy prices, global supply chains, and financial markets. Natural Disasters & Climate Change: Widespread disruptions from natural disasters (e.g., fires, earthquakes, severe weather) or man-made events could damage facilities, inventory, and impair distribution. Climate change could also reduce or delay construction activity and make certain markets less desirable for homebuilding.

Legal Proceedings:

• Construction Defect Claims: Builders FirstSource, Inc. is involved in a number of known and threatened construction defect legal claims. While generally covered by existing insurance programs above deductibles, the possibility of a non-estimable loss exists due to the early stage of proceedings, uncertain outcomes, and complex nature of claims, which could have a material adverse effect.
• Other Claims: The Company is involved in various other claims and lawsuits incidental to its ordinary course of business, including asbestos personal injury suits related to legacy acquired businesses. Management believes the outcome of these other proceedings will not have a material adverse effect, though future adverse judgments could be material.

Tax Strategy & Considerations

Tax Profile:

• Effective Tax Rate: The effective tax rate for 2025 was 15.1%, a decrease from 22.3% in 2024. This decrease was primarily driven by the benefit of income tax credits, the impact of state income taxes, and discrete tax adjustments, relative to a decreased income before income taxes.
• Geographic Tax Planning: The Company is primarily subject to income and other taxes in the U.S., with very limited exposure in certain foreign jurisdictions.
• Tax Reform Impact: The H.R.1 - One Big Beautiful Bill Act, enacted on July 4, 2025, made permanent key elements of the Tax Cuts and Jobs Act, including 100% bonus depreciation and domestic research cost expensing. While it did not materially impact 2025 income tax expense, it is anticipated to have a material impact on future financial results, including cash flows, by reducing cash tax payments and increasing operating cash flows.
• Deferred Tax Assets/Liabilities: As of December 31, 2025, the Company reported a net deferred tax liability of $155.0 million, an increase from $148.2 million in 2024, primarily due to the bonus depreciation and domestic research cost expensing elements of the Act.

• Tax Credit Carryforwards: Includes $4.9 million in state tax credit carryforwards and $65.4 million in federal tax credit carryforwards, most of which have no expiration date.
• Unrecognized Tax Benefits: The balance for uncertain tax positions was $20.3 million as of December 31, 2025, excluding penalties and interest.
• Tax Audits: The Company is currently under IRS audit for its 2019, 2020, and 2021 tax years and reports income-based tax in 42 states with various years open to examination.

Insurance & Risk Transfer

Risk Management Framework:

• Insurance Coverage: Builders FirstSource, Inc. maintains what it believes to be suitable and adequate insurance coverage in excess of its self-insured amounts. This coverage primarily addresses physical loss to property, business interruptions, workers’ compensation, employee healthcare, and comprehensive general and auto liability.
• Self-Insurance Programs: The Company operates self-insurance programs, which are supported by $79.6 million in outstanding letters of credit under its Revolving Facility as of December 31, 2025.
• Risk Transfer Mechanisms: The Company engages an external actuarial professional quarterly to assess and estimate total outstanding insurance liabilities, which are developed from past claims experience and discounted based on estimated future payment streams at the risk-free rate.
• Insurance Reserves: Total insurance reserve balances were $216.6 million as of December 31, 2025. Of this, $121.4 million was recorded as other long-term liabilities. Claims exceeding stop-loss limits, amounting to $25.9 million, are expected to be recovered under insurance policies.
