NextSource Materials Executes Binding Offtake

Agreement with Mitsubishi Chemical Corporation to

Supply SuperFlake® Graphite Anode Material

for the North American EV Market

Highlights

• Multi-year offtake agreement signed with Mitsubishi Chemical Corporation for supply

of c. 9,000 tonnes per annum (tpa) of anode active material

• Partnering with Mitsubishi Chemical Corporation to supply major OEM manufacturer

anode active material for its North American electric vehicle (EV) market

• Accelerates development of NextSource’s Battery Anode Facility in the Middle East

• Significant milestone towards achieving vertical integration by 2027

TORONTO, ON / ACCESS Newswire / August 5, 2025 / NextSource Materials Inc. (TSX:NEXT)

(OTCQB:NSRCF) (NextSource or the Company) and Mitsubishi Chemical Corporation (MCC),

Japan’s largest chemical company and a leading supplier of anode active material (AAM) to original

automotive equipment manufacturers (OEMs), have enter ed into a binding, multi -year offtake

agreement (the Offtake Agreement). Under the terms of the Offtake Agreement, NextSource and

MCC have partnered to supply AAM to a major OEM for the North American EV market. NextSource

will produce and supply intermediate AAM to MCC’s Japan plant where MCC will produce final AAM

for the OEM’s EV battery cell manufacturing facilities in North America.

This Offtake Agreement represents a major milestone for NextSource in its strategy to become one

of very few vertically integrated graphite producers outside of China. The Company is now prioritizing

the development of a large-scale Battery Anode Facility (BAF) in the Middle East to meet the volume

capacities required for MCC and has identified several prospective sites in the United Arab Emirates

(UAE). These locations offer streamlined permitting processes, robust infrastructure, and strategic

proximity to other OEMs, enabling the Company to accelerate its timeline and meet growing demand

for high-value graphite anode active material.

Hanré Rossouw, President and CEO of NextSource, stated,

“We are excited to have entered into a partnership with Mitsubishi Chemical Corporation through a

binding offtake agreement for the production of active anode material in the Middle East, leveraging

high-quality graphite feedstock from our Molo mine in Madagascar. This partnership underscores our

commitment to delivering sustainable, high -performance anode materials to meet the growing

demand from OEM and battery manufacturers. By integra ting world -class resource supply with

advanced processing capabilities, we are building a resilient and scalable solution that supports

global electrification efforts.”

Through the phased development of its BAFs, NextSource is establishing a significant downstream

value-added business capable of large -scale production of coated, spheronized, and purified

graphite (CSPG). These facilities will serve as a secure, transparent, and fully traceable source of

supply for battery and OEM customers, entirely decoupled from existing Asian supply chains, and a

critical alternative for US Government-compliant supply chains. In July 2025, the U.S. imposed a

substantial 160% total tariff on anode -grade graphite imports from China, combining a 93.5% anti -

dumping duty with additional countervailing measures.

More than 95% of the anode (negative) side of EV batteries is made from graphite, making it the

most critical raw material of all battery metals (Benchmark Mineral Intelligence, July 2025). In parallel,

NextSource has begun preparations to expand its Molo mine operations to ensure sufficient and

secure graphite feedstock supply to support the Offtake Agreement with MCC.

Today’s announcement also underpins NextSource’s engagement with strategic financing partners

where it is in advanced discussions regarding assistance in funding construction of both the large -

scale BAF and Molo mine expansion.

Offtake Agreement Terms

The Offtake Agreement designates NextSource as the sole supplier of c. 9,000 tpa of intermediate

AAM to MCC for a multi-year term from the commencement of production of the Company’s BAF.

This Agreement is further underpinned by a rigorous qualification process. Through close technical

collaboration between NextSource and MCC to supply AAM from high-quality SuperFlake®

graphite concentrate, the qualification process will be finalized in 2026 through the installation of

BAF processing equipment, of which approximately half has already been purchased and awaiting

installation. SuperFlake® anode active material will be processed by MCC in Japan and supplied to

its OEM customer’s cell manufacturing facility in North America, with full-scale ramp-up from 2027.

The pricing formula negotiated with MCC is based on an agreed upon price formula that comprises

both a fixed and variable price component which underpins the economics of the project and

secures capacity for the offtaker.

The Offtake Agreement is subject to conditions precedent and contains standard termination rights,

which are customary for an Offtake Agreement of this nature.

Offtake Capacity Requirements Underpin NextSource’s Growth Strategy

Through close technical collaboration, qualification AAM from NextSource, using SuperFlake®

graphite from Molo Phase 1 as feedstock, has been provided to and evaluated by MCC for the OEM’s

battery manufacturer, confirming compliance with its specific anode quality and performance

requirements.

The Company has begun preparations for an industry -scale Molo Phase 2 expansion , which is

expected to benefit from larger economies of scale, while continuing to qualifying its graphite

products and servicing existing key customers through Phase 1 campaign production.

The completion of the technical and economic studies for both the mine and a UAE-based BAF will

inform the final investment decision s, including capital requirements and detailed financing plans.

The significant potential of an expanded Molo Phase 2 and large-scale BAF in the Middle East offer

a strong foundation for growth by securing further offtake agreements for SuperFlake® AAM.
