PolyMet Disclosures
This news release contains certain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, which include all statements that do not relate solely to historical or current facts, such as statements regarding PolyMet’s expectations, intentions or strategies regarding the future, including strategies or plans as they relate to the Arrangement. Forward-looking statements are frequently, but not always, identified by words such as “expects,” “anticipates,” “believes,” “intends,” “estimates,” “potential,” “possible,” “projects,” “plans,” and similar expressions, or statements that events, conditions or results “will,” “may,” “could,” or “should” occur or be achieved or their negatives or other comparable words. Forward–looking statements relate to future events or future performance and reflect management’s expectations or beliefs regarding future events including, but not limited to, statements with respect to the Arrangement, including the anticipated timing of the Special Meeting and of the completion of the Arrangement, and other statements that are not historical facts. Because such statements are based on expectations as to future results and are not statements of fact, actual results may differ materially from those projected and are subject to a number of known and unknown risks and uncertainties, including: (i) uncertainties relating to the ability of the parties to receive in a timely manner and on satisfactory terms, the necessary shareholder approval (including the minority approval), and final court approval; (ii) risks relating to the ability of the parties to satisfy, in a timely manner, the other conditions to the completion of the Arrangement, and other expectations and assumptions concerning the Arrangement; (iii) risks and uncertainties relating to present and future business strategies; and (iv) local and global economic condition risks. The anticipated dates indicated may change for a number of reasons, including the inability to receive, in a timely manner, the necessary shareholder (including the minority approval) and final court approval, the necessity to extend the time limits for satisfying the other conditions to the completion of the Arrangement or the ability of the Board of Directors to consider and approve, subject to compliance by the Company of its obligations in this respect under the agreement providing for the Arrangement, a superior proposal for the Company. All such factors are difficult to predict and are beyond PolyMet’s control. While the list of risks and uncertainties presented here is, and the discussion of risks and uncertainties to be presented in the information circular will be, considered representative, no such list or discussion should be considered a complete statement of all potential risks and uncertainties. Unlisted factors may present significant additional obstacles to the realization of forward-looking statements. Consequences of material differences in results as compared with those anticipated in the forward-looking statements could include, among other things, business disruption, operational problems, financial loss, and legal liability to third parties and similar risks, any of which could have a material adverse effect on the completion of the Arrangement and/or PolyMet’s consolidated financial condition and results of operations. In light of the significant uncertainties in these forward-looking statements, PolyMet cannot assure you that the forward-looking statements in this communication will prove to be accurate, and you should not regard these statements as a representation or warranty by PolyMet, its directors, officers or employees or any other person that PolyMet will achieve its objectives and plans in any specified time frame, or at all.

The forward-looking statements speak only as of the date they are made. PolyMet undertakes no obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by applicable law. Readers are cautioned not to place undue reliance on these forward-looking statements.

Specific reference is also made to risk factors and other considerations underlying forward-looking statements discussed in the Circular under the heading “Risk Factors”, PolyMet’s most recent Annual Report on Form 40-F for the fiscal year ended December 31, 2022, and in our other filings with Canadian securities authorities and the U.S. Securities and Exchange Commission.

The Annual Report on Form 40-F also contains the Company’s mineral resource and other data as required under National Instrument 43-101.
