SUPPLEMENT TO THE PROXY STATEMENT
FOR THE 2026 ANNUAL MEETING OF STOCKHOLDERS
To Be Held On July 23, 2026
On June 9, 2026, Loop Industries, Inc. (the “Company”) filed its definitive proxy statement (the “Proxy Statement”) relating to its 2026 Annual Meeting of Stockholders (the “2026 Annual Meeting”) with the Securities and Exchange Commission, and made the Proxy Statement available to stockholders on or about that same day. Subsequent to that date, the Company’s Board of Directors (the “Board”) has appointed Jeffrey R. Geygan as a director and has nominated him for election at the 2026 Annual Meeting. In connection with the appointment, the Board increased the authorized number of directors of the Company.
This Proxy Statement Supplement (the “Supplement”), dated June 22, 2026, is being made available to stockholders of the Company on or about June 22, 2026, in connection with the solicitation of proxies by the Board for the 2026 Annual Meeting. This Supplement, which adds to and amends the Proxy Statement, includes a new proposal to elect an additional director to the Board and includes an amended notice and proxy card.
New Proposal Five — Election of Jeffrey R. Geygan. Proposal Five, which was added to the agenda for the 2026 Annual Meeting, proposes that Mr. Geygan be elected at the 2026 Annual Meeting to serve until the next annual meeting of stockholders or until his successor has been elected and qualified, or if earlier, his death, resignation, retirement, disqualification or removal.
The amended proxy card or voting instruction form enclosed with this Supplement differs from the proxy card or voting instruction form previously furnished to you with the Proxy Statement dated June 9, 2026. The enclosed proxy card or voting instruction form includes the election of the additional director nominee as a new Proposal Five. If you have already voted, we encourage you to resubmit your vote on all five proposals by submitting the amended proxy card or voting instruction form enclosed with this Supplement or by submitting a proxy by Internet by following the procedures on your amended proxy card or voting instruction form. However, if you return, or have returned, an original proxy card or voting instruction form, your proxy will still remain valid for all of the other proposals and director nominees except Mr. Geygan because he is not listed as a nominee on the original proxy card or voting instruction form, and will be voted at the 2026 Annual Meeting unless revoked. PLEASE NOTE THAT IF YOU SUBMIT A NEW PROXY CARD OR VOTING INSTRUCTION FORM, IT WILL REVOKE ALL PRIOR PROXY CARDS OR VOTING INSTRUCTION FORMS, SO IT IS IMPORTANT TO INDICATE YOUR VOTE ON EACH PROPOSAL ON THE NEW PROXY CARD OR VOTING INSTRUCTION FORM.
Except for the new Proposal Five and the amended notice and proxy card, this Supplement does not modify, amend, supplement or otherwise affect any matter presented for consideration in the Proxy Statement. This Supplement should be read in conjunction with the Proxy Statement, which contains important additional information.
