Battery Mineral Resources' ESI delivers strong monthly results and advances Universal Carrier Platform

Vancouver, British Columbia--(Newsfile Corp. - June 17, 2026) - Battery Mineral Resources Corp. (TSXV: BMR) (OTCQB: BTRMF) (" Battery " or " BMR " or the " Company ") is pleased to provide shareholders with an update on its wholly owned subsidiary, ESI Energy Services Inc. ( "ESI" ), operating under the brand Ozzie's, Inc. ( "Ozzie's" ). ESI is a leading designer and manufacturer of specialized equipment serving the renewable and conventional energy sectors and is headquartered in Phoenix, Arizona. "The first half of 2026 represents a significant milestone in ESI's growth trajectory," said Laz Nikeas, CEO of BMR.

"Strong financial performance and the advancement of the Universal Carrier platform highlight the strength of our business and the progress we are making in executing our long-term growth strategy. We believe Ozzie's is well positioned to benefit from growing demand for specialized and autonomous equipment across utility-scale solar, battery storage, data center, and broader energy infrastructure markets." Strong First Quarter 2026 Financial Results ESI delivered a strong start to 2026, reporting revenue of $7.3 million for the three months ended March 31, 2026, representing a 50% increase over the same period in 2025. Growth was driven by robust rental demand and machine sales across the Company's core product lines.

Income from continuing operations for the quarter was $1.9 million compared to $0.6 million in the first quarter of 2025. Adjusted EBITDA * for the quarter was $2.8 million, representing an adjusted EBITDA margin * of 38% and an 85% improvement compared to the first quarter of 2025. The results reflect continued operating leverage and disciplined cost management across the business. * Adjusted EBITDA is a non-IFRS financial measure and adjusted EBITDA margin is a non-IFRS ratio.

See "Non-IFRS Financial Measures" below. Strong Monthly Performance Projected in April and May 2026 Building on its strong first quarter results, ESI projects monthly revenue of approximately $3.2 million for each of April and May 2026 and an adjusted EBITDA margin * in the cumulative April and May period generally consistent with first quarter 2026. Management believes this performance reflects sustained demand across ESI's rental and equipment sales businesses, supported by active project activity throughout the utility-scale solar and broader energy infrastructure markets.

These unaudited financial results are preliminary in nature, have not been reviewed by the Company's auditors, and remain subject to quarter-end financial closing procedures and potential adjustment. Actual results may differ from these estimates. * Adjusted EBITDA margin is a non-IFRS financial measure. See "Non-IFRS Financial Measures" below.

Universal Carrier Field Testing Underway Ozzie's is pleased to announce that field testing has commenced on its Universal Carrier, previously disclosed as the Omni Crawler platform, a next-generation modular tracked vehicle platform designed to address labor challenges in the utility-scale solar and broader energy construction sectors. Production models of the Universal Carrier are expected to be unveiled in November at the 2026 RE+ Conference in Las Vegas, one of the largest solar and clean energy events in North America. The Universal Carrier is a purpose-built, tracked vehicle platform featuring a modular attachment architecture intended to enable a single machine to perform multiple construction functions.

Contractors are expected to be able to configure the platform with a range of proprietary and third-party attachments, which management believes may reduce equipment fleet requirements, support lower labor requirements, and improve project execution efficiency. The platform is being designed to operate in the demanding terrain commonly encountered in large-scale solar installations and other utility-scale construction environments. Management believes that the autonomous and modular technologies being developed for the Universal Carrier may provide future applications across Ozzie's existing and future product lines.

The underlying platform capabilities, including autonomous operation, precision navigation, and interchangeable tooling interfaces, may support future opportunities in battery storage construction, data center development, and other utility infrastructure markets. Outlook for Remainder of 2026 ESI enters the remainder of 2026 with strong operating momentum and an expanding product development pipeline. Key anticipated milestones include: Completion of Universal Carrier field trials; Unveiling of the production model at RE+ 2026; Continued ramp-up of expanded manufacturing operations; and Ongoing growth in equipment rentals and equipment sales.

Based on current operating performance and management's expectations regarding future business activity, ESI is projecting full-year 2026 revenue of approximately $30 million to 32 million, with adjusted EBITDA margins generally consistent with year-to-date performance. Management remains focused on delivering profitable growth while positioning Ozzie's as a provider of autonomous equipment for the energy infrastructure sector.
