VANCOUVER, British Columbia & SEATTLE--(BUSINESS WIRE)--Sep. 8, 2022-- Zymeworks Inc. (“Zymeworks” or the “Company”) (NYSE: ZYME), a clinical-stage biopharmaceutical company developing multifunctional biotherapeutics, today announced that the proxy statement (“Proxy Statement”) and related materials, dated September 2, 2022 for its special meeting of securityholders (the “Special Meeting”) have been filed publicly and are being mailed to securityholders. The Special Meeting will be held on Friday, October 7, 2022, at 9:00 a.m. Pacific time at the Pearl Room, Fairmont Pacific Rim, 1038 Canada Place, Vancouver, BC V6C 0B9 to approve the previously announced plan to become a Delaware corporation (the “Redomicile”). The record date for the meeting is August 24, 2022. Proxies submitted must be received by 9:00 a.m. Pacific time on Wednesday, October 5, 2022.

At the Special Meeting, Zymeworks securityholders will be asked to consider the Redomicile resolution to approve a series of transactions, including a corporate redomicile (collectively, the “Redomicile Transactions”). Pursuant to the Redomicile Transactions, holders of Zymeworks’ common shares will receive one share of common stock of Zymeworks Delaware Inc., a wholly-owned subsidiary of Zymeworks Inc., and which will become the parent corporation in connection with the completion of the Redomicile (“New Zymeworks”), or one exchangeable share in the capital of an indirect, wholly-owned subsidiary of New Zymeworks, as applicable, for each Zymeworks’ common share owned immediately prior to the Redomicile Transactions (with the aggregate number of exchangeable shares issued subject to a cap) as further outlined in the proxy statement.

The board of directors of Zymeworks (the “Zymeworks Board”) recommends that Zymeworks securityholders vote FOR the Redomicile resolution. The Company believes that the Redomicile will enhance long-term value for securityholders, as well as better position the Company for future growth. The Company also believes that the Redomicile may provide greater opportunities to expand its institutional investor base and may enable New Zymeworks to be eligible for inclusion in certain leading indices, providing opportunities for increased value of Zymeworks common shares and enabling New Zymeworks to be more closely aligned with its peers in the biotechnology sector. Moreover, the Zymeworks Board believes that, if zanidatamab is approved, the United States will be a key geography for the commercialization of zanidatamab, and that a significant portion of counterparties in potential monetization opportunities for the Company’s early-stage product candidates are located in the United States.

Subject to receipt of necessary approvals, including from securityholders, the New York Stock Exchange and the Supreme Court of British Columbia, it is anticipated that the Redomicile will be completed as soon as practicable following the date of the Special Meeting. A Notice of Special Meeting and Proxy Statement/Prospectus and a form of proxy or voting instruction form are being mailed to all securityholders and will also be available under the Company’s issuer profile on SEDAR at and on EDGAR at

Your vote is very important regardless of the number of Zymeworks common shares, Zymeworks warrants and/or Zymeworks incentive awards that you own. If you have questions or need help voting, contact Kingsdale Advisors at 1-855-476-7981 (within North America), or at 1-416-867-2272 (outside North America), or by email at
