Tax Strategy & Considerations

Tax Profile:

• Effective Tax Rate: 31% in 2024, up from 25% in 2023.
• Geographic Tax Planning: Operates in many countries and U.S. states. Subject to changes in tax laws, treaties, or regulations.
• Tax Reform Impact:
  • Louisiana Tax Reform Bills: Signed into law December 4, 2024, effective January 1, 2025, and January 1, 2026. Reduces corporate state income tax rate, repeals corporate state franchise tax, and eliminates preferential apportionment treatment for foreign trade zones. Resulted in a one-time charge of approximately $45 million in Q4 2024 for revaluation of state deferred tax assets and liabilities.
  • Pillar Two (Global Minimum Tax): EU member states agreed to adopt a 15% minimum tax, effective 2024. Other jurisdictions (Canada, Japan, South Korea, Vietnam, UK, Singapore, Switzerland) have enacted similar legislation. Westlake Corporation anticipates qualifying for at least one safe harbor in most jurisdictions, with immaterial impact for others.
  • Inflation Reduction Act of 2022 (IRA): Contains revisions including a 15% corporate minimum income tax and a 1% excise tax on stock repurchases. Not expected to have a material impact on consolidated financial statements.

Insurance & Risk Transfer

Risk Management Framework:

• Insurance Coverage: Maintains property, business interruption, and casualty insurance in accordance with customary industry practices. However, not fully insured against all potential hazards, including losses from wars or terrorist acts, and certain policies may have coverage limitations and deductibles. Terrorism insurance coverage is limited and expensive, with exclusions for acts of war, foreign governments, nuclear, biological, and chemical attacks.
• Risk Transfer Mechanisms: Uses derivative instruments (commodity swaps, futures, forwards, options) to reduce price volatility risk on some feedstock commodities. Uses foreign exchange hedging contracts (e.g., net investment hedges with €150 million notional value at December 31, 2024) and euro-denominated debt as non-derivative net investment hedges to mitigate foreign currency exchange rate risk. Does not currently hedge variable interest rate debt but may do so in the future.
