Item 4.01 Changes in Registrant's Certifying Accountant

(a) Dismissal of Previous Independent Registered Public Accounting Firm

On November 24, 2025, the Audit Committee of the Board of Directors (the "Audit Committee") of AbCellera Biologics Inc. (the "Company") approved the dismissal of KPMG LLP ("KPMG") as the Company's independent registered public accounting firm, effective following the completion of KPMG's audit of the Company's consolidated financial statements for the fiscal year ending December 31, 2025, and the filing of the Company's Annual Report on Form 10-K for that fiscal year. The dismissal was not related to any disagreements with KPMG on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure.

The audit reports of KPMG on the Company's consolidated financial statements for the fiscal years ended December 31, 2024 and December 31, 2023 did not contain an adverse opinion or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope, or accounting principles.

During the fiscal years ended December 31, 2024 and December 31, 2023, and the subsequent interim period through the date of this Current Report on Form 8-K, there were no i) disagreements as defined in Item 304(a)(1)(iv) of Regulation S-K between the Company and KPMG on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, and ii) no reportable events as defined in Item 304(a)(1)(v) of Regulation S-K.

The Company has provided KPMG with a copy of the disclosures it is making in this Current Report on Form 8-K and has requested that KPMG furnish the Company with a letter addressed to the Securities and Exchange Commission stating whether it agrees with the statements made herein and, if not, stating the respects in which it does not agree. A copy of such letter provided by KPMG, dated November 28, 2025, is filed as Exhibit 16.1 to this Current Report on Form 8-K.

(b) Engagement of New Independent Registered Public Accounting Firm

As part of the Audit Committee’s ongoing oversight and assessment of the independent registered public accounting firm, the Audit Committee initiated a formal audit firm tender process earlier this year. The Committee invited several registered public accounting firms to participate in this process. Following this extensive evaluation process, on November 24, 2025, the Audit Committee selected Ernst & Young LLP ("EY") as the Company's new independent registered public accounting firm for the fiscal year ending December 31, 2026, subject to the completion of EY's standard client acceptance and independence procedures and execution of an engagement letter, and effective following the completion of KPMG’s audit of the Company’s consolidated financial statements for the fiscal year ending December 31, 2025, and the filing of the Company’s Annual Report on Form 10-K for that fiscal year.

During the fiscal years ended December 31, 2024 and December 31, 2023, and the subsequent interim period through the date of this Current Report on Form 8-K, neither the Company nor anyone acting on its behalf consulted with EY on any of the matters described in Items 304(a)(2)(i) and (ii) of Regulation S-K.
