5E Advanced Materials, Inc. reported a net loss of $12.1M for the quarter ended March 31, 2026 and a nine‑month loss of $33.7M. Operating expenses were $12.3M for the quarter, driven largely by depreciation, project expenses and a $1.6M impairment of horizontal sidetrack wells.
Cash and cash equivalents increased to $25.4M as of March 31, 2026, helped by equity financings including a February 2026 offering that generated net proceeds of about $33.2M. Despite these financings, management states there is substantial doubt about the company’s ability to continue as a going concern without additional capital.

5E Advanced Materials, Inc. is exiting its Australian listing while keeping its U.S. listing. The company plans to voluntarily delist its CHESS Depositary Interests from the Australian Securities Exchange, with trading suspension expected on May 26, 2026 and delisting effective after the close on May 28, 2026.
After the suspension date, holders will no longer be able to trade CDIs on the ASX, but the company’s common stock will continue to trade on the Nasdaq Global Select Market under the symbol FEAM. The change is not expected to have a material impact on financial position or operating results apart from savings in compliance and other costs associated with the ASX listing. The company intends to provide CDI holders additional information about their rights related to the delisting.
5E Advanced Materials, Inc. director Jonathan A. Siegler has filed an initial Form 3, which identifies him as a board member of the company. The filing shows no reported transactions or derivative positions and no buy, sell, acquire, or dispose activity in this disclosure.
5E Advanced Materials, Inc. appointed Jonathan Siegler to its board of directors, effective April 13, 2026. He will serve until the next annual meeting and until a successor is elected or he departs earlier.
Siegler was designated by BEP Special Situations IV LLC (Bluescape) under a Fourth Amended and Restated Investor and Registration Rights Agreement with Bluescape and Ascend Global Investment Fund SPC.

Siegler replaces Graham van’t Hoff as one of Bluescape’s designees but van’t Hoff remains board chair.

His RSUs also vest in full upon voluntary resignation effectiveness, a change in control, or death or disability. He entered into the company’s standard director and officer indemnification agreement, and the company notes he may be deemed to have an interest in transactions with Bluescape described in prior disclosures.
