MONTRÉAL, CANADA, November 12, 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 third quarter ended September
30, 2026. This period was defined by the continued advancement of the Company’s cornerstone projects: the Matawinie Mine and the
13ktpy Bécancour Battery Material Plant. Construction activities at the Matawinie Mine progressed as planned and within the overall
project budget, while required activities in support of a FID targeted in the upcoming months continued to advance for the 13ktpy Bécancour
Battery Material plant.
“The third quarter was about disciplined
execution and steady progress across key areas of our business,” said Eric Desaulniers, NMG Founder, President and Chief Executive
Officer. “At the Matawinie Mine, our teams continued to translate plans into infrastructure on the ground, while maintaining our
focus on schedule, cost control and responsible project delivery. In parallel, working closely with our partners, we continued to advance
the work required to support a targeted FID for our 13ktpy Bécancour Battery Material Plant in the upcoming months. Beyond project
development, we continued to strengthen the capabilities and relationships that will support NMG over the long term, from applied innovation
to our strengthening collaboration with Eni with the addition of one of their representatives to our Board. We remain focused on delivering
each step with rigour and building a strong foundation for the integrated graphite platform we are developing in Québec, Canada.”

 |
 |
In the third quarter, construction activities
continued to progress as planned and remained within the overall budget, with C$67 million incurred in project expenditures as of September
30, 2026.
The Company reports close to 71,000 on-site
construction and engineering hours worked over the third quarter. Construction activities included:
| · | Concrete pours for building and mineral processing
equipment foundations; |
| · | Excavation and backfill of infrastructure at
the industrial platform; |
| · | Excavation of water control structures; |
| · | Backfill of material into the overburden and
organic stockpiles; |
| · | Ongoing permit/authorization applications for
the construction managed in line with the project execution schedule; |
| · | Continued advancement of detailed engineering
and procurement of key equipment and construction packages. |
Furthermore, NMG continues to advance the remaining
steps toward financial close of the senior debt facilities which is expected in the upcoming weeks.
In October, the Company obtained mining lease
no. 1057 for its Matawinie Mine from Québec’s Ministry of Natural Resources and Forests. The mining lease grants the Company
the right to mine the graphite deposit and marks a major regulatory milestone for the project. This milestone follows several years of
environmental, social and regulatory processes and reflects NMG’s commitment to developing the Matawinie Mine according to high
standards of environmental performance and sustainable development.
In addition, following the approval of the Closure
Plan for the Matawinie Mine in the second quarter, the first instalment of the required financial guarantee was completed in October through
the placement of a surety bond.
Planned key construction activities in the fourth quarter include:
| · | Continued advancement of civil and concrete works,
with focus on maximizing concrete placement prior to the winter period; |
| · | Advancement of awards for construction and equipment
packages required in 2027; |
| · | Continued progress in detailed engineering to
support tender and construction needs. |
13ktpy Bécancour Battery Material Plant
In the third quarter, the Company continued to advance the required
technical, commercial and financing activities supporting a FID targeted in the upcoming months.
Key activities during this period included:
| · | The advancement into the detailed engineering
phase to refine and optimize the process design; |
| · | Ongoing due diligence activities with partners; |
| · | The continued advancement of optimization activities;
and |
| · | The ongoing collaboration with Panasonic Energy
to ensure the plant design meets their key requirements and expectations. |
In addition, Panasonic Energy has reiterated its
intent to support this project, which may entail an equity investment by Panasonic at the FID of the 13ktpy Bécancour Battery Material
Plant, in line with their initial investment in 2024.
Planned key activities in the fourth quarter include
further advancement of the above-mentioned activities as well as the continued optimization of capital structure and negotiations of major
contracts for the production equipment and for the construction.
In parallel, 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.
Commercial Strategy and Value Creation
NMG has established a diversified commercial foundation
across key graphite markets through binding offtake agreements with Panasonic Energy for the lithium-ion battery market, Traxys for the
refractory market, and the Government of Canada for specialized graphite applications. These agreements, representing approximately 70%
of the Matawinie Mine production, provide commercial visibility across large-volume and specialized markets and validate the relevance
of NMG’s planned product portfolio. In addition, the Company continues to advance its commercialization strategy and is actively
engaged with other tier-1 potential customers interested in the remaining volume of NMG’s Phase 2 production for natural flake graphite,
active anode material, and/or specialized graphite materials for niche applications.
Building on this foundation, NMG’s strategy
is focused on maximizing the value generated from its planned graphite production through the development of additional value-added opportunities.
Potential avenues include additional active anode material capacity and the valorization of by-products and tailings. The execution of
these initiatives could enable NMG to capture additional value across its production base, diversify its sources of potential revenue
and progressively expand its earnings-generating capacity.
In the immediate near-term, NMG remains focused on the disciplined
and rigorous execution of the construction of the Matawinie Mine and on advancing the remaining activities in support of a targeted FID
for the 13ktpy Bécancour Battery Material Plant project, while continuing to work closely with its partners and stakeholders to
advance these priorities.
