Nouveau Monde Graphite Inc. filed Prospectus Supplement No. 2 dated April 13, 2026 to qualify a treasury offering of 45,600,000 subscription receipts at US$1.84 each, for gross proceeds of US$83,904,000 (approximately CAD$116.2 million). Each subscription receipt entitles the holder to one common share upon satisfaction of escrow release conditions, including obtaining shareholder approvals and completing a concurrent private placement.

Concurrently, the company entered into subscription agreements with Investissement Québec, Canada Growth Fund and ENI S.p.A. for 115,847,791 common shares at the same price, for gross proceeds of US$213,159,935.44 (approximately CAD$295.2 million). Together with senior secured project debt facilities of US$335 million (approximately CAD$464.0 million) from Export Development Canada and Canada Infrastructure Bank, the equity financings are expected to fully fund construction of the 106 ktpy Phase-2 Matawinie Mine.

Net proceeds from the public offering will fund the design, engineering and construction of the Phase-2 Matawinie Mine, with a portion allocated to general and administrative expenses and working capital. Half of the underwriters' 5% fee is paid at closing and half is escrowed; if escrow release conditions are not met by the July 31, 2026 termination time, investors receive back the full issue price plus their pro rata share of earned interest.

Canadian legal counsel are Stein Monast L.L.P. for the corporation and Fasken Martineau DuMoulin LLP for the underwriters. U.S. counsel are Dorsey & Whitney LLP for the corporation and DLA Piper LLP (US) for the underwriters.
