Power of Attorney for SEC Filings

This filing details a Power of Attorney granted by Victor Sandor, a director of AbCellera Biologics Inc., to Tryn Stimart. Ms. Stimart, as Chief Legal and Compliance Officer, is authorized to execute various U.S. Securities and Exchange Commission (SEC) forms on behalf of Mr. Sandor. These forms include Form ID, Form 3 (Initial Statement of Beneficial Ownership), Form 4 (Statement of Changes in Beneficial Ownership), Form 5 (Annual Statement of Beneficial Ownership), and Schedules 13D and 13G, along with any necessary amendments. The authorization covers the completion, execution, and timely filing of these documents with the SEC and other relevant authorities. The Power of Attorney also grants broad authority for any action deemed beneficial, in the best interest of, or legally required by Mr. Sandor. It specifies that the attorneys-in-fact are not assuming Mr. Sandor's compliance responsibilities under Section 16 or Regulation 13D-G. The Power of Attorney remains in effect until Mr. Sandor is no longer required to file such forms or until earlier revoked in writing. It supersedes any prior powers of attorney and will expire if the attorney-in-fact ceases to be a director of the Company. The document was executed on June 11, 2026.
