• Tax Reform Impact: The company is evaluating the impact of the "One Big Beautiful Bill Act" (OBBB), signed in July 2025, which makes permanent many of the tax provisions originally enacted under the Tax Cuts and Jobs Act of 2017 and introduces modifications to certain U.S. corporate tax provisions. The company does not expect it to have a material effect on its financial statements as of June 30, 2025.

Insurance & Risk Transfer

Risk Management Framework: 5E Advanced Materials, Inc. maintains workers’ compensation insurance and a general liability policy to address potential liabilities for injury or death. However, there is no assurance that coverage will be adequate or available on acceptable terms in the future.

• Insurance Coverage: The company maintains insurance policies to mitigate risks, but acknowledges that potential costs associated with liabilities not covered by insurance, or in excess of coverage, could be substantial.
• Risk Transfer Mechanisms: Reclamation obligations at the 5E Boron Americas (Fort Cady) Complex are secured by a surety bond and pledged certificates of deposits, totaling $1.5 million as of June 30, 2025, held for the benefit of state and federal regulatory agencies.

Business Cyclicality & Seasonality

Demand Patterns: The company's business is exposed to cyclicality due to its dependence on industries such as energy, automotive, agriculture, transportation, petrochemical, and original equipment manufacturing. Demand for its products can fluctuate based on broader economic conditions, energy prices, consumer demand, and government infrastructure funding decisions. While there are no material restrictions on operations due to seasonality, the Project's location in the Mojave Desert makes it susceptible to extreme summer heat and flash flooding, which could impact operations. Planning & Forecasting: Demand forecasting and planning are informed by preliminary market studies evaluating future supply and demand dynamics for boric acid, calcium chloride, and gypsum.
