**Item 4.01&nbsp;&nbsp;&nbsp;&nbsp;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.

## Exhibit 16.1

![](abcl_exhibit161001.jpg)

November 28, 2025 Securities and Exchange Commission Washington, D.C. 20549 Ladies and Gentlemen: We are currently principal accountants for AbCellera Biologics Inc. (the Company) and, under the date of February 27, 2025, we reported on the consolidated financial statements of the Company as of and for the years ended December 31, 2024 and 2023 and the effectiveness of internal control over financial reporting as of December 31, 2024. On November 26, 2025, we were notified that the Company engaged Ernst & Young LLP as its principal accountant for the year ending December 31, 2026 and that the auditor-client relationship with KPMG LLP will cease upon completion of the audit of the Company's consolidated financial statements as of and for the year ended December 31, 2025, and the effectiveness of internal control over financial reporting as of December 31, 2025, and the issuance of our reports thereon. We have read the Company's statements included under Item 4.01 of its Form 8-K dated November 28, 2025, and we agree with such statements, except that we are not in a position to agree or disagree with the Company's statements in Item 4.01(b). Very truly yours, /s/ KPMG LLP Chartered Professional Accountants Exhibit 16.1
