(a) Dismissal of Independent Registered Public Accounting Firm.

On October 9, 2024, The Cannabist Company Holdings Inc. (the “Company”) notified Davidson & Company LLP (“Davidson”) that it was being dismissed as the Company’s independent registered public accounting firm effective October 9, 2024. The decision to dismiss Davidson as the Company’s independent registered public accounting firm was recommended by the Company’s audit committee (the “Audit Committee”) and approved by the Company’s board of directors (the “Board”).

Davidson’s reports on the consolidated financial statements of the Company as of and for the years ended December 31, 2023, and 2022 did not contain any adverse opinion or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope, or accounting principles.

During the two fiscal years ended December 31, 2023, and the subsequent interim periods through October 9, 2024, there were no (i) disagreements, within the meaning of Item 304(a)(1)(iv) of Regulation S-K promulgated under the Securities Exchange Act of 1934, as amended (“Regulation S-K”), and the related instructions thereto, with Davidson on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Davidson, would have caused Davidson to make reference to the subject matter of the disagreements in connection with its reports; or (ii) “reportable events” within the meaning of Item 304(a)(1)(v) of Regulation S-K and the related instructions thereto.

The Company provided Davidson with the disclosures under this Item 4.01 of Form 8-K and requested Davidson to furnish the Company with a letter addressed to the Securities and Exchange Commission stating whether it agrees with the statements made by the Company in this Item 4.01 of Form 8-K and, if not, stating the respects in which it does not agree. Davidson’s letter is filed as Exhibit 16.1 to this Current Report on Form 8-K.

(b) Appointment of New Independent Registered Public Accounting Firm.

On October 9, 2024, the Board approved, on the recommendation by the Audit Committee, the appointment of PKF O’Connor Davies, LLP (“PFK”) as the Company’s new independent registered public accounting firm for the fiscal year ending December 31, 2024, effective immediately. During the Company’s two most recent fiscal years ended December 31, 2023, and 2022, and the subsequent interim periods through October 9, 2024, neither the Company nor anyone acting on its behalf consulted with PFK with respect to: (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s consolidated financial statements, and PFK did not provide either a written report or oral advice to the Company that PFK concluded was an important factor considered by the Company in reaching a decision as to any accounting, auditing, or financial reporting issue, or (ii) (a) any matter that was either the subject of a disagreement (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) or (b) a “reportable event” as described in Item 304(a)(1)(v) of Regulation S-K.
