Nano One® Materials Corp. ("Nano One" or the "Company") is a clean technology company with patented processes for the production of lithium-ion battery cathode materials that enable secure and resilient supply chains by driving down cost, complexity, energy intensity, and environmental footprint. Nano One has filed its condensed interim consolidated financial statements (the "financial statements"), and management's discussion & analysis ("MD&A") as at and for the nine months ended September 30, 2023 ("Q3 2023") and is pleased to provide the following highlights from Q3 2023.

Corporate Milestones and Developments for Q3 2023

Strategic Investment and Collaboration Agreement with Sumitomo Metal Mining

On October 5, 2023, Nano One and Sumitomo Metal Mining Co., Ltd. ( "SMM", together with Nano One, the "Companies") closed a transaction whereby the Companies agreed to a strategic equity investment in Nano One by SMM of approximately $17,000,000 and entered into a collaboration agreement under which the Companies will work together to accelerate the commercial production of lithium iron phosphate ("LFP"), cathode active materials ("CAM") and nickel-rich CAM chemistries, such as lithium nickel manganese cobalt oxide ("NMC"). SMM is a leading vertically integrated miner, refiner and producer of CAM.

Nano One issued a total of 5,498,355 common shares (the "Shares"), representing approximately 5% of the current issued and outstanding Shares of Nano One, at $3.07 per Share ($16,879,950) in a non-brokered private placement.

Nano One intends to use the proceeds principally towards the conversion of its existing Candiac LFP manufacturing facility to a One-Pot production scale pilot plant, nickel and manganese-rich engineering, and piloting activities, and for working capital purposes.

Pre-Feasibility Study of One-Pot LFP Production Lines Completed

On October 23, 2023, the Company announced the completion of its Front-End Loading (FEL) 2 pre-feasibility study with Hatch Ltd., which estimates that the capacity for a One-Pot LFP production line is 12,500 tonnes per annum ("tpa") and that two such lines (25,000 tpa) could be built within a 167,000 sq. ft. building, making it more efficient in size, footprint, and capital cost than other commercial methods of making LFP.

Nano One is actively exploring site locations for its expansion plans, including but not limited to its existing site in Candiac, Québec, and is engaged with governments in various jurisdictions where access to financial incentives and technology attraction programs could further increase shareholder value and stakeholder interests.

LFP from Commercial Size Reactors and Customer Samples Delivered

On September 14, 2023, the Company announced that recent One-Pot trials in the existing reactors at the Candiac plant have produced LFP at commercial scale with performance results consistent to lab scale. Nano One has leapfrogged to full commercial size reactors and its LFP can be shipped to select customers for evaluation.

With Nano One's existing commercial reactors, it has continued to optimize trials in the existing commercial scale reactors, reproducing lab and development results. This demonstrates the One-Pot process can scale to commercial volumes and advances the de-risking of the technology at commercial scale. This rapid advancement allows commercial scale LFP samples to be sent to qualified customers, for thorough evaluation and validation for the purposes of entering binding offtake agreements.

Q3 2023 Financial Position and Results

• Cash position at quarter end of $26.0 million, plus approximately $17.0 million subsequently raised through a strategic equity investment by SMM resulting in a cash position post-SMM investment of $43.0 million
• Working capital at quarter end of $22.0 million ($39.0 million post-SMM investment)
• Total assets of $46.0M (pre-SMM investment) at quarter end
• Total liabilities of $7.4M with no long-term debt at quarter end
• Net use of cash and cash equivalents of $8.4M for the quarter ($13.4M year-to-date)
• Total gross investment (capitalized and expensed) before allocations of government funding on at its Candiac plant including equipment, retrofitting, engineering, and expansion totalled $8.6M (year-to-date)

Annual budgeting planning activities are underway, with a base shelf prospectus to be filed following standard company governance practices to fund expansion plans.
