Corporate Updates

NMG Provides Q2 2026 Update and Highlights a Defining Quarter Shifting

From Development to Execution of Its Matawinie Mine

Highlights

 Finalization of agreements and establishment of a strategic supply and marketing

framework with the Government of Canada translating into a long-term take-or-

pay agreements covering 30ktpy of flake graphite to be produced at the Matawinie

mine. The marketing structure allows NMG to market the Government of Canada’s

committed volumes with an upside-sharing mechanism on proceeds above a fixed

price, and the ability for Canada to store product.

 On May 15, 2026, the Company completed for the Phase 2 Matawinie Mine a

private placement with strategic investors for aggregate gross proceeds of C$295

million (US$213M). In addition, aggregate gross proceeds of C$132 million

(US$97M) from the Company’s subscription receipts issued on April 16, 2026, were

released upon satisfaction of the applicable escrow release conditions. These

transactions formed part of an aggregate equity financing package of C$427 million

(US$310M).

 The participation of Eni S.p.A., NMG’s new strategic investor, in the private

placement was complemented by a letter of intent to advance commercial

discussions toward a potential 15ktpy graphite concentrate offtake from the Phase 2

Matawinie Mine or equivalent in active anode material.

 Following this successful private placement and the previously announced debt

financing commitment of US$335 million, NMG confirmed the FID for the Phase 2

Matawinie Mine and officially launched construction.

 The Company recently completed a Class 3 AACE cost estimate for the

development of the 13ktpy Bécancour Battery Material Plant, with an estimated

CAPEX of C$374 million (US$267M). In addition, it is pursuing the advancement of

engineering and accelerating due diligence processes of its various stakeholders in

support of a targeted FID in H2 2026.

 Twelve-month rolling Total Recordable Injury Frequency Rate (TRIFR) of 0.95 for

the Company’s employees and 0 for the contractors active at the Matawinie mine

construction site and no major environmental incidents as of June 30, 2026.

 Looking ahead, NMG remains focused on the next phase of execution across its

integrated business model which includes, amongst others, pursuing the civil works

at the Matawinie site, continuing to advance the conditions required to support a

targeted FID for its 13ktpy Bécancour Battery Material Plant and pursuing ongoing

business development.

 Period-end cash position of C$461 million.

MONTRÉAL--(BUSINESS WIRE)--August 13, 2026--Nouveau Monde Graphite Inc. (“NMG”

or the “Company”) (NYSE : NMG, TSX : NOU) provides a quarterly update on its financial

and operational performance and strategic progress for the second quarter ended June 30, 2026.

Aligned with its strategy to develop one of the first fully integrated natural graphite production

platforms in the G7, this second quarter was marked by the Financial Investment Decision (FID)

and construction launch of the Matawinie Mine, while the Company also actively continued to

advance key activities supporting a targeted FID in H2 2026 for its 13ktpy Bécancour Battery

Material plant.

“The second quarter of 2026 was a key chapter in NMG’s journey,” said Eric Desaulniers, NMG

Founder, President and Chief Executive Officer. “With the successful financing and launch of

construction activities at the Matawinie Mine, we transitioned from years of planning and

development into execution all while remaining focused on advancing the next major

development stage for our 13ktpy Bécancour Battery Material Plant. At a time when supply

chain security, industrial resilience and strategic autonomy have become key priorities, these

milestones reflect the dedication of our team, the confidence of our partners and shareholders,

and the continued strategic importance of NMG’s integrated graphite operations in Western

markets. The momentum from the second quarter is carrying us into our next stage of growth,

with a clear focus on advancing construction at the Matawinie Mine, securing FID for our 13ktpy

Bécancour Battery Material Plant, and continuing to position NMG for the opportunities that lie

ahead.”

Matawinie Mine (Phase 2)

In May, following the successful private placement and debt financing commitment, NMG

confirmed the FID for the Phase 2 Matawinie Mine and officially launched construction in the

presence of federal and provincial leaders, including the Prime Minister of Canada, as well as

community representatives, Indigenous partners and industry stakeholders.

Since the launch of construction, the Company reports ongoing progress at the Matawinie Mine,

with activities remaining within the overall budget. As of June 30, 2026, C$33 million had been

incurred in project expenditures and C$167 million had been committed, reflecting ongoing

construction, engineering, procurement and project execution activities. Primary focus has been

on civil works, with first concrete pours undertaken in July 2026. Key activities also included

excavation for the concentrator and associated infrastructure at the industrial platform,

excavation of water control structures, backfill of material into the overburden and organic

stockpiles, continued advancement of detailed engineering and procurement of key equipment

and construction packages and initiation of deposits on critical long-lead equipments.

In addition, the amendment to Decree 47-2021 for the Matawinie Mine (Phase 2) was officially

published on August 5, 2026. It updates the initial government authorization issued in 2021 to

reflect the project's evolution since then. This amendment primarily relates to certain operational

parameters of the project, including a minor southward extension of the open pit made possible

through the acquisition of additional surface rights, and the corresponding increase in the

authorized annual graphite production capacity from 100,000 tonnes to 106,000 tonnes.

13ktpy Bécancour Battery Material Plant

The Company recently completed a Class 3 AACE cost estimate for the development of the

13ktpy Bécancour Battery Material Plant, with an estimated CAPEX of C$374 million

(US$267M). In addition, it is pursuing the advancement of engineering and accelerating due

diligence processes of its various stakeholders in support of a targeted FID in H2 2026.

Panasonic Energy has reiterated its intent to support the development of NMG’s Phase 2 facility,

which may entail an equity investment by Panasonic at the FID of the Phase 2 13ktpy Bécancour

Battery Material Plant, in line with Panasonic’s initial investment in 2024.

To support customer demand, NMG also continues various workstreams to develop Additional

Battery Material Plants of active anode material and/or advanced graphite materials production

that could be developed on its existing 200,000-m² adjacent greenfield or other strategically

positioned sites either in North America or in Europe.

Near-term priorities

Looking ahead, NMG remains focused on the next phase of execution across its integrated

business model.

Key priorities include:

 pursuing civil works at the Matawinie site, pouring of concrete foundations for major

equipment and building foundations in advance of the installation of structural steel in

early 2027;

 continuing to advance the conditions required to support a targeted FID for its 13ktpy

Bécancour Battery Material Plant in H2 2026, including the optimization of the capital

structure;

 pursuing ongoing business development, including securing additional offtake

agreements and diversifying NMG’s mix of products.

Alongside these priorities, the Company will continue to actively engage with customers,

shareholders, investors, government partners, Indigenous communities and other stakeholders to

support, amongst others, commercialization efforts and long-term growth.

Planned engagement activities include participation in key industry and investor forums, such as

for example the H.C. Wainwright 28th Annual Global Investment Conference (September 14-16)

and the Maxim Growth Summit 2026 (October 13-14), as NMG continues to maintain strategic

relationships across the critical minerals value chain.

Current Business Opportunities

The Company has observed growing interest from potential customers seeking to diversify and

secure their critical minerals supply chains as they try to navigate the current geopolitical

situation, characterized by growing trade frictions between Europe, China and the United States

and near-term uncertainty in certain regions of the Middle East and Africa.

NMG’s integrated business model, underpinned by low-cost hydropower, the proximity between

the mine and the planned transformation asset, and Canada’s and Québec’s established industrial

ecosystems, remains a key differentiator.

In the near future, the Corporation intends to expand commercial discussions with respect to the

30,000 tonnes of flake graphite expected to be produced at the Matawinie mine and which is

currently earmarked for the spot market. Amongst others, it intends to advance commercial

discussions with Eni S.p.A towards a potential 15ktpy graphite concentrate offtake or equivalent

in active anode material.

At the same time, it is also exploring various business opportunities, mainly with customers that

are part of the lithium-ion battery supply chain, may it be for electric vehicles or the fast-growing

Battery Energy Storage Systems (BESS) market.

Notwithstanding the outcome of these specific commercial discussions, the Corporation has also

approached other large G7 integrated conglomerates that have investments or investment plans in

battery plants making them potential customers for the Corporation’s natural graphite anode

material.
