5E Advanced Materials, Inc.: 5E Advanced Materials Reports Key Fiscal Q3 2026 Commercial and Operational Milestones

First Boric Acid Offtake Agreement Signed, Specialty Product Development and Financing Efforts Advance

HESPERIA, CA / ACCESS Newswire / May 13, 2026 / 5E Advanced Materials, Inc. ("5E" or the "Company") highlighted significant commercial, operational, and financing progress during the third quarter of the fiscal 2026 conference call as it advances development of its Fort Cady Project.

Key quarterly highlights included:

First Commercial Offtake Agreement Executed

5E signed its first boric acid heads of agreement with a domestic industrial end user for:

• 7,500 short tons per year of boric acid supply, with optional expansion to 10,000 tons annually

• Fixed pricing with annual escalation

• Initial five-year term with automatic renewal provisions extending up to ten years

Management believes the agreement represents an important milestone towards establishing a portfolio of bankable commercial arrangements to support future project financing activities. The agreement follows a March customer engagement initiative involving meetings with 12 industrial boron customers and distributors across multiple end markets. 5E is advancing a pipeline of multiple proposals at various stages and continues to see growing demand for a reliable domestic boron supply chain.

Meta Boric Acid Development Expands Product Portfolio

5E successfully developed a stable, free-flowing meta boric acid containing approximately 80% B2O3-equivalent content, creating a potential higher-value specialty product opportunity. 5E has filed a provisional patent application related to the technology and has initiated customer qualification testing.

The Company believes the product could provide:

• Enhanced pricing relative to conventional boric acid

• Improved logistics economics due to higher boron concentration

• Access to additional specialty materials markets

Ferroboron Trial Program Progressing

Initial testing has commenced under the Company's magnet-grade ferroboron development program. Samples are expected to be produced in the coming weeks and distributed to potential customers. The initiative supports 5E's strategy to expand into higher-value boron derivative products serving permanent magnet, specialty steel, industrial, and defense applications.

Financing and Balance Sheet Momentum

During the quarter, 5E continued advancing discussions with the Export-Import Bank of the United States ("EXIM") regarding potential project financing support, including under EXIM's "Make More in America" initiative and Engineering Multiplier Program. The Company also highlighted its strengthened balance sheet following completion of a $36 million public equity offering in February 2026, which was more than four times oversubscribed.

Outlook

The Company believes the quarter's progress continued to de-risk the Fort Cady Project through commercial validation, financing advancement, and product diversification. 5E stated that the quarter's progress meaningfully advances the Company's strategy of becoming a vertically integrated domestic supplier of boron and advanced boron derivative products.

Management remains focused on:

• Securing additional offtake agreements

• Advancing financing readiness

• Expanding commercial engagement globally

• Progressing engineering activities for Phase 1 of the Fort Cady Project

These initiatives are intended to position the Company for the next phase of development, including engineering advancement and construction readiness.
