## Exhibit 99.1

**Exhibit 99.1**

**SCHEDULE 51-102F3**

**Material Change Report**

**1.** **Name and Address of the Corporation** 

**NOUVEAU MONDE GRAPHITE INC.** (the "**Corporation**")<br> 481 Rue Brassard<br> Saint-Michel-des-Saints QC, J0K 3B0

**2.** **Date of Material Change** 

November 12, 2025

**3.** **News Release** 

A news release, in French and English versions, was issued on November 12, 2025 through Business Wire and filed on SEDAR+.

**4.** **Summary of Material Change** 

The Corporation announced the issuance of the results of a segregated and updated feasibility study for the Phase-2 Matawinie Mine.

**5.** **Full Description of Material Change** 

**Matawinie Mine Feasibility Study Results**

The Corporation released the results of its feasibility study completed in accordance with the National Instrument 43-101 – *Standards of Disclosure for Mineral Projects* ("**NI 43-101**") for the Phase-2 Matawinie Mine ("**NI 43-101 Technical Report: 2025 Feasibility Study for the Matawinie Graphite Mine**"). The Corporation tasked BBA Inc. and various specialized consultants with the preparation of a segregated and updated feasibility study in light of the contemplated potential sequenced final investment decision starting with the Phase-2 Matawinie Mine followed by the Phase-2 Bécancour Battery Material Plant.

With a project globally unchanged, other than the exclusion of Phase 2 of the Bécancour Battery Material Plant, the NI 43-101 Technical Report: 2025 Feasibility Study for the Matawinie Graphite Mine refined some financial parameters to reflect the commercial agreements and latest capital expenditures ("**CAPEX**") projections in line with ongoing procurement activities. Results continue to demonstrate technical and economic viability of the Phase-2 Matawinie Mine.

| 1 | The Mineral Resources provided in this table were estimated by Yann Camus P.Eng., Qualified Person of SGS Geological Services, using current Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") Standards on Mineral Resources and Reserves, Definitions and Guidelines. |
| 2 | Mineral Resources that are not Mineral Reserves have not demonstrated economic viability. Additional trenching and/or drilling will be required to convert Inferred and Indicated Mineral Resources to Measured Mineral Resources. There is no certainty that any part of a Mineral Resource will ever be converted into Reserves. |
| 3 | All analyses used for the Resource Estimates were performed by ALS Minerals Laboratories and delivered as % C(g), internal analytical code C-IR18. |
| 4 | Inferred Mineral Resources represent material that is considered too speculative to be included in economic evaluations. Additional trenching and/or drilling will be required to convert Inferred Mineral Resources to Indicated or Measured Mineral Resources. It cannot be assumed that all or any part of the Inferred Resources will ever be upgraded to a higher Resource category. |
| 5 | Current Resources effective November 12, 2025. |
| 6 | Mineral Resources are stated at a cut-off grade of 1.78% C(g). |
| 7 | Quality control standards used for these Mineral Resources returned within acceptable limits, no significant bias was found. |

There is no certainty that the economic forecasts on which the NI 43-101 Technical Report: 2025 Feasibility Study for the Matawinie Graphite Mine is based will be realized. There are a number of risks and uncertainties identifiable to any new project and usually cover the mineralization, process, financial, environment and permitting aspects. Following an analysis of the major risks to the project, a P50 management risk reserve of $21M is recommended. This reserve is not included in the capital cost estimate but is within the range of the financial sensitivity analysis of the capital cost. The top risks are 1) construction productivity differing from baseline estimate; 2) longer-than-expected specialized equipment delivery times; and 3) contractor bids differing from the budget.

A sensitivity analysis reveals that the viability of the Phase-2 Matawinie Mine will not be significantly vulnerable to variations in capital and operating costs within the margins of error associated with the NI 43-101 Technical Report: 2025 Feasibility Study for the Matawinie Graphite Mine estimates. However, the viability of the Phase-2 Matawinie Mine remains more vulnerable to the USD/CAD exchange rate and the larger uncertainty in future market prices.

Scientific and technical information presented in this material change report was reviewed and approved by Jean L'Heureux, P.Eng. (BBA), Yann Camus, P.Eng. (SGS Geological Services) and Jeffrey Cassoff, P.Eng. (BBA), Qualified Persons as defined under NI 43-101.
