AMERICAN BATTERY TECHNOLOGY COMPANY FY26 Q3 Earnings

Unaudited Condensed Consolidated Balance Sheets

Reno, Nev., May 11, 2026 (GLOBE NEWSWIRE) -- American Battery Technology Company  (NASDAQ: ABAT), an integrated domestic critical mineral company that is commercializing its internally-developed technologies for both primary critical mineral manufacturing and secondary critical mineral recycling, released the financial results for the third quarter of fiscal year 2026 (FY26) ended on March 31, 2026.

Over the quarter, American Battery Technology Company (ABTC) significantly ramped and streamlined operations at its Nevada critical mineral recycling facility and achieved record breaking revenue with a 64% increase quarter-over-quarter, while cost of goods sold increased only 11% over the same period, and correspondingly the Company achieved its first-ever positive gross margin. This substantial growth in the throughput of its recycling facility has allowed ABTC to capitalize on strong market conditions and solidify itself as one of the dominant critical mineral recyclers in the United States.

Financial Highlights, Third Quarter of FY26:

$7.8 million in Revenue, a 64% increase from the previous quarter
- And an additional $0.3 million income from interest for the quarter

$7.1 million in Cost of Goods Sold, an 11% increase from the previous quarter
- $5.8 million cash cost of goods sold (non-GAAP1), with exclusion of non-cash expenses of depreciation and stock-based compensation
$0.7 million in Gross Margin, ABTC’s first positive gross margin operations
- $2.0 million in Adjusted Gross Margin (non-GAAP1), with exclusion of non-cash expenses of depreciation and stock-based compensation
$38.5 million cash, balance as of end of quarter
- Includes $37.7 million in unrestricted and $0.8 million in restricted cash
$0.0 million debt, Company currently holds zero debt

“Demonstrating positive gross margin from operations is a major milestone that many growth companies never achieve and allows us to enable self-sustaining operations of our critical mineral recycling facility,” stated American Battery Technology Company CEO Ryan Melsert. “The gross profit generated by this facility provides additional resources as we continue to scale the operations at this first critical mineral recycling facility, construct and bring to operations our second recycling facility, and construct and ramp our critical mineral lithium mine and refinery to support the U.S. establishing dominance with a closed loop domestic critical mineral supply chain.”

Critical Mineral Recycling Highlights: Scaled and Streamlined Operations

Significantly increased throughput and operational effectiveness of recycling operations, resulting in substantially increased revenue and only relatively lower increase in cost of goods sold

Growth was fueled by increased processing of high-value recycled products from Battery Energy Storage Systems (BESS) supporting datacenters and artificial intelligence (AI) facilities, end-of-life electric and hybrid vehicles, and consumer electronics

Continued innovation and cost-down optimizations drove improvements in gross margins and facility utilization

As one of the few recyclers in the Western U.S capable of handling CERCLA-classified waste, ABTC’s Nevada lithium-ion battery recycling facility, permitted by the EPA in the spring of 2025 under CERCLA, has emerged as a critical revenue engine recovering valuable metals from high-demand, hard-to-recycle battery sources

Continued development of a second critical mineral recycling facility in the Southeast U.S., with plans to substantially scale capacity compared to company’s existing recycling plant in Nevada, positioning the company for expanded, matched-market impact

The establishment of new supply chain partnerships with leading BESS facilities and automotive OEMs, providing near-term and long-term material flows to support the Company’s growing operations

Primary Lithium from Claystone Highlights: Accelerating a Domestic Supply Chain

ABTC’s Tonopah Flats Lithium Project (TFLP), one of the largest lithium deposits in the U.S., continues to secure its position as a cornerstone of the domestic critical mineral supply chain to support demand and drive future growth

ABTC has successfully advanced its claystone-to-lithium hydroxide demonstration plant and is now focused on scaling through construction of a full-scale commercial mine and refinery

Designated as a Fast-41Transparency Covered Project under federal initiatives to boost and onshore domestic critical mineral supply, the TFLP benefits from streamlined federal permitting efforts, accelerating its path to commercialization of a new U.S. lithium resource and domestic production of critical mineral lithium hydroxide (LiOH)

The Company achieved a critical milestone by completing and submitting all baseline studies for the National Environmental Policy Act (NEPA) review process, a two-year effort overseen by the Department of Interior’s Bureau of Land Management (BLM), involving over 40 regulatory agencies and stakeholders across 21 study areas

The Company has initiated its Definitive Feasibility Study, the final phase of engineering and financial analysis required to move the project into commercial production, with recommendations published in its October 2025 Pre-Feasibility Study (PFS) for its Tonopah Flats Lithium Project

The PFS detailed the technical and financial roadmap for commercialization of this domestic-US critical mineral lithium mine and refinery, and supports the project’s robust economic potential and potential strategic importance:

- Designed production of 30,000 tonnes per year of lithium hydroxide monohydrate (LHM), with project economics calculated for a 45-year life-of-min

- After-tax NPV at 8% of $2.57 billion and IRR of 21.8%, underscoring its financial viability

- Highly competitive production cost of $4,307 per tonne, representing a 9.2% reduction from the Company’s April 2024 Initial Assessment

- Total TFLP lithium resources (measured, indicated, and inferred) increased approximately 11% to 21.3 million tonnes LHM, and establishment of 2.73 million tonnes of proven (0.98) and probable (1.75) reserves, compared to April 2024 Initial Assessment

The company will host a listen-only earnings webcast today, Monday, May 11 at 4:30 p.m. ET.

Inferred Resource
Inferred Mineral Resource is that part of a mineral resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. The level of geological uncertainty associated with an Inferred Mineral Resource is too high to apply relevant technical and economic factors likely to influence the prospects of economic extraction in a manner useful for evaluation of economic viability. Because an Inferred Mineral Resource has the lowest level of geological confidence of all mineral resources, which prevents the application of the modifying factors in a manner useful for evaluation of economic viability, an Inferred Mineral Resource may not be considered when assessing the economic viability of a mining project, and may not be converted to a mineral reserve.

Indicated Resource
Indicated Mineral Resource is that part of a mineral resource for which quantity and grade or quality are estimated on the basis of adequate geological evidence and sampling. The level of geological certainty associated with an Indicated Mineral Resource is sufficient to allow a qualified person to apply modifying factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit. Because an Indicated Mineral Resource has a lower level of confidence than the level of confidence of a Measured Mineral Resource, an Indicated Mineral Resource may only be converted to a Probable Mineral Reserve.

Measured Resource
Measured Mineral Resource is that part of a mineral resource for which quantity and grade or quality are estimated on the basis of conclusive geological evidence and sampling. The level of geological certainty associated with a Measured Mineral Resource is sufficient to allow a qualified person to apply modifying factors, as defined in this section, in sufficient detail to support detailed mine planning and final evaluation of the economic viability of the deposit. Because a Measured Mineral Resource has a higher level of confidence than the level of confidence of either an Indicated Mineral Resource or an Inferred Mineral Resource, a Measured Mineral Resource may be converted to a Proven Mineral Reserve or to a Probable Mineral Reserve.

Mineral Reserve
Mineral Reserve is an estimate of tonnage and grade or quality of indicated and measured mineral resources that, in the opinion of the qualified person, can be the basis of an economically viable project. More specifically, it is the economically mineable part of a measured or indicated mineral resource, which includes diluting materials and allowances for losses that may occur when the material is mined or extracted.

Probable Mineral Reserve
Probable Mineral Reserve is the economically mineable part of an indicated and, in some cases, a measured mineral resource.

Proven Mineral Reserve
Proven Mineral Reserve is the economically mineable part of a measured mineral resource and can only result from conversion of a measured mineral resource.

Pre-Feasibility Study
A Preliminary Feasibility Study (or Pre-Feasibility Study) is a comprehensive study of a range of options for the technical and economic viability of a mineral project that has advanced to a stage where a qualified person has determined (in the case of underground mining) a preferred mining method, or (in the case of surface mining) a pit configuration, and in all cases has determined an effective method of mineral processing and an effective plan to sell the product. A Pre-Feasibility Study includes a financial analysis based on reasonable assumptions, based on appropriate testing, about the modifying factors and the evaluation of any other relevant factors that are sufficient for a qualified person to determine if all or part of the Indicated and Measured Mineral Resources may be converted to mineral reserves at the time of reporting. The financial analysis must have the level of detail necessary to demonstrate, at the time of reporting, that extraction is economically viable. A Pre-Feasibility Study is less comprehensive and results in a lower confidence level than a feasibility study. A Pre-Feasibility study is more comprehensive and results in a higher confidence level than an Initial Assessment.

Initial Assessment
An Initial Assessment is a preliminary technical and economic study of the economic potential of all or parts of mineralization to support the disclosure of mineral resources. The Initial Assessment must be prepared by a qualified person and must include appropriate assessments of reasonably assumed technical and economic factors, together with any other relevant operational factors, that are necessary to demonstrate at the time of reporting that there are reasonable prospects for economic extraction. An Initial Assessment is required for disclosure of mineral resources but cannot be used as the basis for disclosure of mineral reserves. An Initial Assessment is preliminary in nature and includes Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied that would enable them to be classified as mineral reserves. There is no certainty that the economic results of an initial assessment will be realized. The mineral resource estimates presented in the ABTC Tonopah Flats Initial Assessment were performed by third-party, qualified person RESPEC, LLC and were classified by geological and quantitative confidence in accordance with the Securities and Exchange Commission (SEC) Regulation S-K 1300.
