NANO ONE ANNOUNCES AT-THE-MARKET OFFERING

Nano One Materials Corp. has entered into an equity distribution agreement with Canaccord Genuity Corp. and Roth Canada Inc. to establish an at-the-market equity issuance program (the ATM program). Pursuant to the distribution agreement, the company may distribute up to $15-million of common shares in the capital of the company, from time to time through the agents, subject to the approval of the Toronto Stock Exchange (the TSX).

The ATM program is being established pursuant to a prospectus supplement dated the date hereof to the company's short form base shelf prospectus dated April 26, 2024, each filed with the securities regulatory authorities in all the provinces of Canada. Sales, if any, will be made as at-the-market distributions as defined in NI 44-102 -- Shelf Distributions, including sales made directly on the TSX or any other Canadian marketplace, at the prevailing market price at the time of sale; as such, prices may vary among purchasers and over time.

The ATM program will be effective until the earliest of: (i) April 27, 2026; (ii) the issuance and sale of all of the offered shares subject to the distribution agreement by the agents; (iii) the receipt of notice from the British Columbia Securities Commission that the base shelf prospectus has ceased to be effective in accordance with applicable Canadian securities laws; and (iv) termination of the distribution agreement in accordance with its terms.

"ATM programs are a cost-effective and flexible way to raise capital over time, and they enhance our ability to respond when ideal market conditions exist," said Carlo Valente, chief financial officer. "The ATM program will provide us with an additional opportunity to strengthen our balance sheet incrementally and it also leverages previously announced policy funding support from the governments of Quebec and Canada, as well as the U.S. Department of Defense."

The company currently intends to use the net proceeds, if any, to finance continuing operations. The company may reallocate the net proceeds of the ATM program from time to time, giving consideration to its strategy relative to the market, development, and changes in the industry and regulatory landscape, as well as other conditions relevant at the applicable time.
