American
Battery Technology Company Announces Highest Ever Gross Profit and Successful Appeal for Reinstatement of $57 Million US Department of
Energy Grant in Fourth Quarter FY2026 Financial Results
Increase
in gross profit of 86% through continued scale-up and implementation of operational efficiencies at its domestic-US critical mineral
recycling facility, and reinstatement of competitive $57 million grant from U.S. Department of Energy
Reno,
Nev., August 20, 2026 — American Battery Technology Company (NASDAQ: ABAT),
an integrated domestic critical mineral manufacturing company that is commercializing its internally-developed technologies for both
primary critical mineral manufacturing and secondary critical mineral recycling, released the unaudited financial results for its fourth
quarter of fiscal year 2026 (FY26) ended on June 30, 2026.
During
the quarter, American Battery Technology Company (ABTC) continued to scale-up and implement operational efficiencies at its Nevada critical
mineral recycling facility and achieved record breaking quarterly revenue of $8.2 million, while simultaneously decreasing cost of goods
sold, resulting in a quarter-over-quarter increase in gross profit of 86% to $1.3 million. This substantial growth in gross profit of
its recycling facility further demonstrates the advantages of ABTC’s internally-developed technologies and its position as one
of the dominant critical mineral recyclers in the U.S.
In
addition to operating its critical mineral recycling facility, ABTC is also developing and constructing its critical mineral mine and
refinery at its Tonopah Flats Lithium Project (TFLP) near Tonopah, Nevada. During the quarter, ABTC announced that it had successfully
won its appeal with the U.S. Department of Energy and had its previously terminated grant for $57 million supporting the $115 million
construction of the first processing train at the TFLP fully reinstated.

Regulatory
Update
A
recently-issued federal directive effectively prohibits the export of black mass for any domestic company from the United States effective
as of August 27, 2026, unless an exception or adjustment is obtained from the Department of Commerce, and if the company is unable to
obtain an exception, the company may be unable to sell black mass to foreign customers, which could result in a material adverse effect
on its revenue, results of operations, financial condition, and ability to fund ongoing operations.
On
July 30, 2026, President Trump issued a Presidential Determination pursuant to Section 101 of the Defense Production Act of 1950, as
amended (the “DPA”), declaring black mass produced from the recycling of lithium-ion batteries to be a critical material
essential to the national security of the United States. On August 6, 2026, the Bureau of Industry and Security (“BIS”) within
the U.S. Department of Commerce published a Temporary Final Rule in the Federal Register titled “DPAS Directive Allocation Order
and Additional Requirements for Recoverable Critical Minerals and Materials” (the “Directive”), which imposes a requirement
that U.S. entities selling black mass allocate 100% of their monthly sales to U.S. persons. The Directive takes effect on August 27,
2026, and remains in effect for approximately one year from the date of publication. The practical effect of the Directive is to prohibit
the export of black mass from the United States unless BIS grants an exception or adjustment.
Sales
of black mass represents the majority of the company’s total revenue, and substantially all of its current black mass customers
are located outside the United States in OECD countries. The company has submitted a request to BIS for an exception from the Directive’s
domestic allocation requirement and is actively engaging with Congressional representatives, government affairs advisors, and other stakeholders
regarding this matter. Under the Directive, companies may submit exception requests on a rolling basis, and BIS intends to respond within
14 days of receipt. Companies may also request a temporary license to continue exports while an exception request is pending.
However,
there can be no assurance that the company’s request for an exception will be granted, that any exception will be granted on terms
that are commercially favorable to the company, or that any exception will be granted within a timeframe that avoids material disruption
to its business and operations. If the company is unable to obtain an exception or other relief from the Directive, or if any exception
is subject to conditions that are commercially impracticable, the company may be unable to sell black mass to all of its foreign customers.
The
loss of its foreign black mass sales revenue could have a material adverse effect on its revenue, results of operations, financial condition,
cash flows, and our ability to fund ongoing operations and growth initiatives. The company may be required to seek alternative income
sources, reduce operating costs, or pursue additional financing. Additionally, even if the company is able to identify and develop domestic
customers for our black mass over time, such development efforts may take considerable time, and the terms of domestic sales may be significantly
less favorable than our existing international arrangements.
The
company is monitoring developments regarding the Directive, including the public comment period (which remains open until November 4,
2026), potential legislative action, and any modifications BIS may make to the Directive or exception process. The company intends to
pursue all available avenues to obtain relief, but it cannot predict the outcome of these efforts or their timing.
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.
