NMG Pays Accrued
Interests
MONTRÉAL,
CANADA, July 1, 2026 – Nouveau Monde Graphite Inc. (“NMG” or the “Company”) (NYSE: NMG,
TSX: NOU) announces the payment of accrued interests as part of a previously announced private placement.
Settlement of
Accrued Interests
Upon the approval
of the Toronto Stock Exchange and the New York Stock Exchange (the “Exchanges”), the accrued interests owed to Investissement
Québec (“Holder”) for the second quarter of 2026 under the unsecured convertible note, as amended and restated, (the
“Note”) issued in connection with the private placement announced by press release dated November 8, 2022, will
be deemed paid.
227,924 common
shares at a price of US$1.48 (each, a “Common Share”) representing an aggregate amount of US$337,328 will be issued and share
certificates will be delivered to the Holder at the maturity, conversion or redemption of the Note in payment of the accrued interests
due on June 30, 2026, for the second quarter of the year. The issuance of Common Shares is subject to the approval of the Exchanges
and, when issued, will be subject to a hold period of four (4) months and one day.
The payment of
interest in the form of Common Shares of the Corporation takes place in favor of Investissement Québec, a holder of more than
10% of the securities of the Company, which constitutes a “transaction with a related party” within the meaning of Regulation
61-101 on measures to protect minority holders during specific transactions (“Regulation 61-101”). However, the directors
of the Company, who voted, have determined that the exemptions from the official valuation obligation and the approval of minority holders,
provided for in sections 5.5 a) and 5.7 1) a) of Regulation 61-101 respectively, may be invoked as neither the fair market value of the
shares issued to this insider nor the fair market value of the consideration paid does not exceed 25% of the market capitalization of
the Company. No director of the Company has expressed a contrary opinion or disagreement in connection with the foregoing.

Cautionary
Note Regarding Forward-Looking Information
This
press release contains “forward-looking information” and “forward-looking statements” within the meaning of applicable
securities laws (collectively, “forward-looking statements”). All statements other than statements of historical fact are
forward-looking statements.
These
statements include, but are not limited to, statements regarding the scheduled payment of interest on the Note, the Company’s ability

Risk
factors that could impact the Note and the interests payables under such Note include, among others, the Company’s ability to generate
sufficient cashflow from operations to service the payment of the interest in cash or in common shares, the fluctuations in the market
price of the Company’s common shares, which may prevent the conversion criteria from being met and force the debt to remain outstanding
until maturity, and availability of sufficient cash reserves or refinancing options to repay the full principal and accrued interest,
in cash or in common shares, upon the expiry date.
A further description
of risks and uncertainties can be found in NMG’s Annual Information Form dated March 25, 2026, including in the section
thereof captioned “Risk Factors”, which is available on SEDAR+ at www.sedarplus.ca and on EDGAR at www.sec.gov.

expectations and plans relating to the future. The Company disclaims any intention or obligation to update or revise any forward-looking
statements or to explain any material difference between subsequent actual events and such forward-looking statements, except to the

MATERIAL CHANGE REPORT
Name and Address of the Corporation
NOUVEAU MONDE GRAPHITE INC. (the “Corporation”)
481 Rue Brassard
Saint-Michel-des-Saints QC, J0K 3B0
Date of Material Changes
April 9 and April 16, 2026
News Releases
News releases relating to the material
changes described herein were disseminated through the facilities of Business Wire and subsequently filed on SEDAR+ on April 9, 2026,
and April 16, 2026.
Summary of Material Changes
On April 9, 2026, the Corporation
entered into: (a) subscription agreements (the “Subscription Agreements”) with Investissement Québec (“IQ”),
Canada Growth Fund Inc. (“CGF”), and ENI S.p.A., through its subsidiary ENI International B.V. (“ENI”),
pursuant to which the Corporation agreed to issue an aggregate of 115,847,791 common shares of the Corporation (the “Common Shares”)
at a price of US$1.84 (the “Offering Price”) per Common Share, for aggregate gross proceeds of approximately US$213
million (the “Private Placement”); and (b) an agreement with a syndicate of underwriters co-led by BMO Capital
Markets and National Bank Financial (the “Bookrunners”), pursuant to which the Corporation would issue, on a “bought
deal” basis, 45,600,000 subscription receipts (the “Subscription Receipts”) at the Offering Price, for gross
proceeds to the Corporation of approximately US$84 million (the “Public Offering”). On April 16, 2026, the Corporation
announced the closing of the Public Offering, and the gross proceeds have been deposited in escrow pending satisfaction of the Escrow
Release Conditions (as defined below).
Full Description of Material Change
Full Description of Material Change
The Private Placement
On April 9, 2026, the
Corporation announced that it had entered into the Subscription Agreements pursuant to which each of IQ, CGF, and ENI has agreed to
subscribe for 33,351,853 Common Shares, 44,452,460 Common Shares and 38,043,478 Common Shares, respectively, at the Offering Price,
for aggregate gross proceeds to the Corporation of approximately US$213 million (or the Canadian dollar equivalent thereof). The
closing of the Private Placement is subject to, among other things, the receipt of the Shareholder Approvals (as defined below). The
Corporation has agreed to certain covenants that are in force between the date of the Subscription Agreements (being April 9,
2026) and the closing of the Private Placement or earlier termination of the applicable Subscription Agreement. The Private
Placement will be made pursuant to exemptions from the prospectus requirements under Canadian securities laws and the Common Shares
issued thereunder will be subject to restrictions on resale for a period of four months from the closing date of the Private
Placement under Canadian securities laws.
The participation of IQ and CGF in the Private
Placement builds on their prior support for the advancement of the phased development of the commercial operations of its Matawinie mine
(the “Phase-2 Matawinie Mine”) and the broader ore-to-battery-material value chain, while ENI’s investment reflects
growing strategic interest from global energy and industrial players in secure, carbon-neutral critical minerals supply.
The Private Placement is part of the final step
in assembling a comprehensive financing package combining senior debt, strategic equity investments, and public-market capital. Upon closing
of the Private Placement, satisfaction of the Escrow Release Conditions in respect of the Public Offering, and satisfaction of conditions
precedent to the previously announced project debt financing, the Corporation expects to have secured all required funding to declare
the final investment decision on the Phase-2 Matawinie Mine and proceed with its design, engineering and construction.
In connection with the equity investment by ENI,
concurrently to the execution of the Subscription Agreement with ENI, ENI and the Corporation entered into a side letter agreement (the
“ENI Side Letter”) and, as a condition to the closing of the equity investment by ENI, ENI and the Corporation have
agreed to enter into: (i) an investor rights agreement (the “ENI Investor Rights Agreement”); and (ii) a
registration rights agreement (the “ENI Registration Rights Agreement”).
Pursuant to the ENI Investor Rights Agreement,
ENI (i) will be required to “lock-up” its Common Shares for a period of 12 months from the date of closing of the Private
Placement and (ii) will be subject to a two-year standstill period from the date of closing of the Private Placement. The ENI Investor
Rights Agreement will also provide ENI with certain board nomination and observer rights, as well as pre-emptive and top-up rights in
connection with future offerings and certain dilution events, in each case subject to ENI maintaining specified ownership thresholds in
the Corporation.
The ENI Registration Rights Agreement will provide
ENI with demand, piggyback and shelf registration rights in respect of the Common Shares held by ENI, subject to customary terms and conditions.
Pursuant to the ENI Side Letter, the Corporation
has agreed to negotiate in good faith the terms of a potential offtake agreement relating to 15,000 tonnes per annum (“tpa”)
of graphite concentrate from the Phase-2 Matawinie Mine or equivalent in active anode material.
Copies of the Subscription Agreements have been
filed in Canada on SEDAR+ at www.sedarplus.ca and in the United States on the SEC’s
website at www.sec.gov under the Corporation’s corporate profile. A form of each
of the ENI Investor Rights Agreement and the ENI Registration Rights Agreement is attached as a schedule to the Subscription Agreement
with ENI.
Each of CGF and IQ are parties to an investor
rights agreement and a registration rights agreement with the Corporation, respectively, dated December 20, 2024, which agreements
remain in force and have been filed in Canada on SEDAR+ at www.sedarplus.ca and in the
United States on the SEC’s website at www.sec.gov under the Corporation’s
corporate profile.
Currently, IQ has beneficial ownership of,
or control or direction over, directly or indirectly, an aggregate of 25,637,260 Common Shares, which represent 15.94% of the issued and
outstanding Common Shares on a non-diluted basis, 19,841,269 Common Share purchase warrants (“Warrants”) with an exercise
price of US$2.38 per Warrant (the “IQ Warrants”) and, under an unsecured convertible note of the Corporation dated
November 8, 2022, as amended and restated on October 27, 2025 (the “IQ Convertible Note”), units comprising
an aggregate of 2,500,000 Common Shares and 2,500,000 Warrants, as well as up to 1,920,176 additional Common Shares issuable in connection
with accrued interest under the IQ Convertible Note, which in the aggregate represent approximately 25.17% of the issued and outstanding
Common Shares on a partially-diluted basis (assuming exercise of the IQ Warrants and conversion of the IQ Convertible Note only and including
1,920,176 Common Shares issuable to IQ in connection with accrued interest under the IQ Convertible Note). Following the completion of
the Private Placement and satisfaction of the Escrow Release Conditions in respect of the Public Offering, IQ is expected to acquire
33,351,853 Common Shares and hold 58,989,113 Common Shares, representing approximately 18.30% of the issued and outstanding Common Shares,
on a non-diluted basis, and with the IQ warrants and the IQ Convertible Note, 24.57% of the issued and outstanding Common Shares on a
partially-diluted basis (assuming exercise of the IQ Warrants and conversion of the IQ Convertible Note only and including 1,920,176 Common
Shares issuable to IQ in connection with accrued interest under the IQ Convertible Note).
Currently, CGF has beneficial ownership of,
or control or direction over, directly or indirectly, an aggregate of 19,841,269 Common Shares, which represent 12.34% of the issued
and outstanding Common Shares on a non-diluted basis, and 19,841,269 Warrants with an exercise price of US$2.38 per Warrant (the
“CGF Warrants”), which in the aggregate represent approximately 21.96% of the issued and outstanding Common
Shares on a partially-diluted basis (assuming exercise of the CGF Warrants only). Following the completion of the Private Placement
and satisfaction of the Escrow Release Conditions in respect of the Public Offering, CGF is expected to acquire 44,452,460 Common
Shares and hold 64,293,729 Common Shares, representing approximately 19.95% of the issued and outstanding Common Shares, on a
non-diluted basis, and with the CGF Warrants, 24.59% of the issued and outstanding Common Shares on a partially-diluted basis
(assuming exercise of the CGF Warrants only).
Shareholder Approvals
Each of IQ and CGF is an “interested party”
within the meaning of Regulation 61-101 respecting Protection of Minority Security Holders in Special
Transactions (“Regulation 61-101”) and the issuance of Common Shares to each of IQ and CGF pursuant to the
Private Placement constitutes a “related party transaction” (collectively, the “Related Party Transactions”)
within the meaning of Regulation 61-101.
Therefore, the issuance of Common Shares to each
of IQ and CGF under the Private Placement requires the approval of a simple majority of the holders of Common Shares at a duly called
meeting of shareholders (the “Meeting”), other than Common Shares beneficially owned, or over which control or direction
is exercised by: (a) the issuer, being the Corporation; (b) an “interested party” (within the meaning of Regulation
61-101); (c) a “related party” to such interested party (within the meaning of Regulation 61-101) (subject to certain
exceptions); and (d) any person that is a joint actor with any party referred to in (b) or (c), which represent IQ and CGF in
respect of the applicable resolution approving the issuance of Common Shares to IQ and CGF, respectively (the “61-101 Shareholder
Approvals”). The issuance of Common Shares to each of IQ and CGF under the Private Placement is also subject to the formal valuation
requirement set out in Regulation 61-101.
In addition to the above, the TSX Company Manual
will require that the Corporation obtain, (i) approval of the issuance of Common Shares to ENI, IQ and CGF under Section 607(g)(i) of
the TSX Company Manual, as the aggregate number of Common Shares issuable to ENI, IQ and CGF exceeds 25% of the Corporation’s
issued and outstanding Common Shares as of the date hereof; (ii) approval of the issuance of Common Shares to each of IQ and CGF
under Section 607(g)(ii) of the TSX Company Manual, as these private placements to insiders exceed 10% of the Corporation’s
issued and outstanding Common Shares as of the date hereof; and (iii) approval of the pricing of the Private Placement under Section 607(e) of
the TSX Company Manual, as the Common Shares issued pursuant to the Private Placement are to be issued at a price per Common Share lower
than the Common Shares’ Market Price (as defined in the TSX Company Manual) less a 15% discount (the “TSX Shareholder Approvals”,
and collectively with the 61-101 Shareholder Approvals, the “Shareholder Approvals”). The TSX Shareholder Approvals
will be required to be obtained by a simple majority of votes cast by holders of Common Shares eligible to vote (excluding the votes of
IQ, CGF and ENI, if any, and their respective associates and affiliates).
The Corporation convened an annual and special
meeting of shareholders to be held on May 13, 2026 at 10:00 a.m. EDT via webcast at https://virtual-meetings.tsxtrust.com/en/1931
to consider the Shareholder Approvals and any related matters. The foregoing description of the Shareholder Approvals is not complete
and additional details regarding the Shareholder
Approvals and the formal valuation will be provided
in a forthcoming management information circular, which, once filed, will be available in Canada on SEDAR+ at www.sedarplus.ca
and in the United States on the SEC’s website at www.sec.gov under the Corporation’s
corporate profile.
The Public Offering
On April 13, 2026, the Corporation entered
into an underwriting agreement with a syndicate of underwriters comprised of the Bookrunners, ATB Capital Markets Corp., Roth Canada, Inc.,
H.C. Wainwright & Co., LLC and Maxim Group LLC (the “Underwriters”), pursuant to which the Underwriters agreed
to purchase, on a bought deal basis, 45,600,000 Subscription Receipts at the Offering Price, for gross proceeds to the Corporation of
approximately US$84 million (the “Underwriting Agreement”).
A copy of the Underwriting Agreement has been
filed in Canada on SEDAR+ at www.sedarplus.ca and in the United States on the SEC’s
website at www.sec.gov under the Corporation’s corporate profile.
The Corporation granted the Underwriters an over-allotment
option (the “Over-Allotment Option”) to purchase, on the same terms and conditions of the Offering, up to an additional
6,840,000 Subscription Receipts (the “Over-Allotment Subscription Receipts”). The Over-Allotment Option was exercised
in full. The gross proceeds from the sale of 52,440,000 Subscription Receipts (including 6,840,000 Subscription Receipts issued pursuant
to the exercise of the Over-Allotment Option) were approximately US$96.5 million. The Offering closed on April 16, 2026 and the Subscription
Receipts began trading on the same date on the Toronto Stock Exchange under the symbol “NOU.R.U”.
In consideration for the services rendered by
the Underwriters, the Corporation has agreed to pay the Underwriters a cash fee equal to 5% of the gross proceeds of the Offering (the
“Underwriters’ Fee”).
Each Subscription Receipt represents the
right to receive, for no additional consideration and without further action, one Common Share of the Corporation upon satisfaction
of the Escrow Release Conditions. If (i) the notices to be provided to TSX Trust Company (the “Subscription Receipt
Agent”) and the Bookrunners by the Corporation certifying that the Escrow Release Conditions have been satisfied (the
“Escrow Release Notice and Direction”) are not delivered on or before 11:59 p.m. (Montréal time) on
July 31, 2026 (unless extended by the Corporation with the prior written consent of the Bookrunners) (the
“Termination Time”), (ii) a “termination event” as such term is defined in the subscription
receipt agreement (the “Termination Event”) to be entered into in the context of the Public Offering has
occurred, or (iii) the Corporation has advised the Bookrunners and the Subscription Receipt Agent or announced to the public
that it does not intend to proceed with obtaining the Shareholder Approvals or completing of the Private Placement (in either case,
the earliest of such times being the “Termination Date”), holders of Subscription Receipts will receive the full
purchase price of the Subscription Receipt, together with their pro rata portion of income (including interest) generated thereon,
calculated from the date of closing of the Offering and up to but excluding the Termination Date (less any applicable withholding
taxes).
The gross proceeds from the Public Offering, less
50% of the Underwriters’ Fee has been deposited and is being held in escrow by the Subscription Receipt Agent (the “Escrowed
Funds”), together with any interest and other income actually earned thereon, and invested in short-term interest bearing or
discount debt obligations issued or guaranteed by the Government of Canada or a province or a Canadian chartered bank, until the earlier
of (i) satisfaction or waiver of the Escrow Release Conditions, and (ii) the Termination Time. Since 50% of the Underwriters’
Fee has been paid by the Corporation, such amount does not form part of the Escrowed Funds. Therefore, the aggregate amount that holders
of the Subscription Receipts shall be entitled to receive from the Subscription Receipt Agent in the event of a Termination Event will
be greater than the aggregate amount of the Escrowed Funds. The Corporation will therefore be required to pay the Subscription Receipt
Agent as agent on behalf of holders of Subscription Receipts an amount equal to 50% of the Underwriters’ Fee such that 100% of the
gross proceeds of the Public Offering, plus the interest or other income actually earned on the investment of the Escrowed Funds, would
be returned to holders of Subscription Receipts.
On or immediately after the closing of the Private
Placement, the Corporation will deliver the Escrow Release Notice and Direction, and the Escrowed Funds, together with interest and other
income actually earned thereon, less 50% of the Underwriters’ Fee, will be released to or as directed by the Corporation.
The escrow release conditions are: (i) the
Corporation obtaining the Shareholder Approvals, (ii) the closing of the Private Placement, and (iii) the satisfaction or waiver
of the other escrow release conditions under the subscription receipt agreement (the “Subscription Receipt Agreement”)
entered into on April 16, 2026 in the context of the Public Offering among the Corporation, the Bookrunners and the Subscription
Receipt Agent (collectively, the “Escrow Release Conditions”).
In connection with the Public Offering, the Corporation
has filed a prospectus supplement in all provinces of Canada (excluding the territories) (the “Prospectus Supplement”)
to the short form base shelf prospectus of the Corporation dated December 5, 2025 (the “Base Shelf Prospectus”)
and the Corporation’s United States registration statement on Form F-10, as amended (File No. 333291778) (the “Registration
Statement”) filed with the United States Securities and Exchange Commission (the “SEC”) under the United
States Securities Act of 1933, as amended, pursuant to the multijurisdictional disclosure system. The final Prospectus Supplement (together
with the related Base Shelf Prospectus) and the Subscription Receipt Agreement filed in Canada are available on SEDAR+ at www.sedarplus.ca.
The final Prospectus Supplement (together with the Base Shelf Prospectus) and the Subscription Receipt Agreement filed in the United States
are available on the SEC’s website EDGAR at www.sec.gov.
The Corporation intends to use the net
proceeds from the Private Placement, the Public Offering and the previously announced senior secured project debt pursuant to a commitment
letter from Export Development Canada and Canada Infrastructure Bank (the “Facilities”)
for funding the design, engineering and construction of the Phase-2 Matawinie Mine and for general and administrative expenses and general
working capital of the Corporation.
