DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q contains statements that we believe are, or may be considered to be, “forward-looking statements.” Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are based on current beliefs, expectations or assumptions regarding the future of the business, future plans and strategies, operational results and other future conditions of the Company. All statements other than statements of historical fact included in this Quarterly Report on Form 10-Q regarding the prospects of our industry or our prospects, plans, financial position or business strategy may constitute forward-looking statements. In addition, forward-looking statements generally can be identified by the use of forward-looking words such as “plans,” “expects” or “does not expect,” “is expected,” “look forward to,” “budget,” “scheduled,” “estimates,” “forecasts,” “will continue,” “intends,” “the intent of,” “have the potential,” “anticipates,” “does not anticipate,” “believes,” “should,” “should not,” or variations of such words and phrases that indicate that certain actions, events or results “may,” “could,” “would,” “might,” or “will,” “be taken,” “occur,” or “be achieved,” or the negative of these terms or variations of them or similar terms. Furthermore, forward-looking statements may be included in various filings that we make with the Securities and Exchange Commission (“SEC”) or press releases or oral statements made by or with the approval of one of our authorized executive officers. Although we believe that the expectations reflected in these forward-looking statements are reasonable, we cannot assure you that these expectations will prove to be correct. These forward-looking statements are subject to certain known and unknown risks and uncertainties, as well as assumptions that could cause actual results to differ materially from those reflected in these forward-looking statements.

Forward-looking statements contained in this Quarterly Report on Form 10-Q include, but are not limited to:

●

the anticipated amount, timing and accounting of contingent, milestone, royalty and other payments under licensing or collaboration agreements;

●

tax positions and contingencies; research and development costs; compensation and other selling, general and administrative expense;

●

foreign currency exchange risk;

●

estimated fair value of assets and liabilities; and impairment assessments;

●

the potential impact of increased competition in the markets in which we compete;

●

patent terms, patent term extensions, patent office actions and expected availability and period of regulatory exclusivity;

●

our plans and investments in our portfolio as well as implementation of our corporate strategy;

●

the risk that we will maintain enough liquidity to execute our business plan;

our expected use of proceeds from sales of our common shares or common share equivalents in offerings or “at-the-market” offerings and the period over which such proceeds, together with existing cash, will be sufficient to meet our operating needs;

the drivers for growing our business, including our plans and intention to commit resources relating to discovery, research and development programs and business development opportunities as well as the potential benefits and results of, and the anticipated completion of, certain business development transactions;

●

the expectations, development plans and anticipated timelines, including costs and timing of clinical trials, filings and approvals, of our products candidates and pipeline programs, including collaborations with third-parties, as well as the potential therapeutic scope of the development and commercialization of our and our collaborators’ pipeline product candidates, if approved;

the timing, outcome and impact of administrative, regulatory, legal and other proceedings related to our patents and other proprietary and intellectual property rights, tax audits, assessments and settlements, pricing matters, sales and promotional practices, product liability and other matters;

our ability to finance our operations and business initiatives and obtain funding for such activities;

●

the direct and indirect impact of health crises on our business and operations, including expenses, the supply chain, manufacturing, cyber-attacks or other privacy or data security incidents, research and development costs, clinical trials and employees;

●

the potential impact of healthcare reform in the United States and measures being taken worldwide designed to reduce healthcare costs and limit the overall level of government expenditures, including the impact of pricing actions and reduced reimbursement for our product candidates, if approved;

●

the impact of the continued uncertainty of the credit and economic conditions in certain countries and our collection of accounts receivable in such countries;

By their very nature, forward-looking statements involve inherent risks and uncertainties, both general and specific, and risks exist that predictions, forecasts, projections and other forward-looking statements will not be achieved. We caution readers not to place undue reliance on these statements as a number of important factors could cause the actual results to differ materially from the beliefs, plans, objectives, expectations, anticipations, estimates and intentions expressed in such forward-looking statements. Risks, uncertainties and other factors which may cause the actual results, performance or achievements of ProMIS Neurosciences Inc. (the “Company”), as applicable, to be materially different from any future results, performance or achievements expressed or implied by such forward-looking information and statements include, but are not limited to, the risks described under the heading “Risk Factors Summary” and in Item 1A—“Risk Factors” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025 filed with the SEC on March 25, 2026 (the “Form 10-K”) as well as the risks described in Item 1A—“Risk Factors” in subsequently filed Quarterly Reports on Form 10-Q.

Readers are cautioned not to place undue reliance on any forward-looking statements contained in this Quarterly Report on Form 10-Q, which reflect management’s opinions only as of the date hereof. Except as required by law, we undertake no obligation to revise or publicly release the results of any revision to any forward-looking statements. You are advised, however, to consult any additional disclosures we make in our reports to the SEC. All subsequent written and oral forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by the cautionary statements contained in this Quarterly Report on Form 10-Q.
