Vancouver, British Columbia--(Newsfile Corp. - September 29, 2026) - Battery Mineral Resources Corp. (TSXV: BMR) (OTCQB: BTRMF) (the "Company" or "BMR") provides an update on its wholly owned subsidiary, ESI Energy Services Inc. ("ESI"), including its performance for the six months ended June 30, 2026 and the proposed expansion of its manufacturing operations in Phoenix, Arizona.

ESI Performance and Manufacturing Expansion Update

As previously reported, for the six months ended June 30, 2026, ESI generated revenue of approximately C$16.4 million, representing a 51% increase from approximately C$10.9 million in the corresponding period of 2025. Income from continuing operations was approximately C$4.8 million, compared with approximately C$1.5 million in the corresponding period of 2025.

To provide additional information regarding ESI's operating performance, the Company is also reporting Adjusted EBITDA for ESI. Adjusted EBITDA for the six months ended June 30, 2026, was approximately C$6.6 million, compared with approximately C$3.2 million in the corresponding period of 2025.^*

^*Adjusted EBITDA is a non-IFRS financial measure. This measure does not have a standardized meaning prescribed by IFRS and may not be comparable to similar measures presented by other issuers. See "Non-IFRS Financial Measure" below for additional information and a reconciliation of Adjusted EBITDA to income from continuing operations.

Laz Nikeas, CEO of BMR, commented:

"ESI continues to see increased demand for its products and services. In 6M 2026, ESI generated revenue growth of approximately 51% compared with 6M 2025. Adjusted EBITDA for the six months ended June 30, 2026 was approximately C$6.6 million, representing an approximately 108% increase compared with the same period in 2025. With continued investment in energy infrastructure in the United States and abroad to support both industrial demand and artificial intelligence ("AI") data center growth, ESI is well positioned to capitalize on these opportunities. Supported by our new commercial banking partner, we are advancing plans to expand ESI's manufacturing footprint to support continued growth, increased manufacturing capacity and improved operating efficiencies."

ESI continues to advance its manufacturing expansion plans and is in the process of finalizing arrangements for a proposed new facility in Phoenix. Subject to completion of the lease and related arrangements, equipment installation and relocation activities are expected to begin in December 2026, with the facility expected to become fully operational in early Q2 2027. The proposed facility would approximately triple ESI's current manufacturing footprint, providing greater manufacturing capacity, improved production flow and additional space to support its expanding portfolio of specialized energy equipment.

If completed as planned, the expanded facility is expected to provide ESI with the infrastructure and flexibility to scale production, increase vertical integration and improve operating efficiencies, accelerate new product development and pursue growth opportunities across its existing and emerging markets.

Non-IFRS Financial Measure

Adjusted EBITDA: Adjusted EBITDA is defined as income from continuing operations before foreign exchange gains and losses, net interest expense, income taxes, depreciation and amortization and intercompany transactions.
