5E Advanced Materials, Inc.

Purchase Obligations

As of June 30, 2025, the Company had purchase order commitments of approximately $3.5 million primarily for drilling and other services related to the Company’s wellfield development program, raw materials for the operation of the SSF, engineering services and vendor tested related to the design of the proposed commercial-scale facility, environmental testing and other corporate services.

Litigation

On July 17, 2023, the Company filed a complaint (the “Complaint”) against a previous construction contractor in the United States District Court for the Central District of California, Eastern Division, alleging, among other things, numerous breaches by the contractor of its contractual obligations to 5EBA under the Procurement and Construction Contract, effective April 26, 2022, by and between 5EBA and the contractor, relating to the construction of the SSF in California (the “Contract”). On August 10, 2023, the contractor filed an answer to the Complaint as well as a counterclaim for, among other things, alleged breaches by 5EBA of its contractual obligations to the contractor under the Contract and has requested relief in the approximate amount of $5.5 million. The Company has filed a response disputing the counterclaims asserted by the contractor. Discovery has begun and is ongoing. During July 2025, the Company and contractor attended mediation, which did not result in a resolution relating to the litigation. An estimate of reasonably probable outcomes cannot be made at this time.
