LONG BEACH, Calif. and TORONTO, Nov. 11, 2026 (GLOBE NEWSWIRE) -- Glass House Brands Inc. ("Glass House" or the "Company") (CBOE CA: GLAS.A.U) (NYSE: GLAS) today announced that BDO USA, P.C. ("BDO") resigned as auditor at the request of the Company, and Macias Gini & O'Connell LLP ("MGO") was reappointed as Glass House's auditor effective November 6, 2026. The resignation and reappointment were approved by the Company's Audit Committee and Board of Directors.

MGO had been the Company's auditor since it became a public company in mid-2021. At the Company's request, MGO resigned as auditor on September 11, 2026 to allow for the appointment of BDO.

In its response letter dated September 11, 2026, MGO agreed with the statements in the Company's notice of change of auditor insofar as they related to MGO. The notice stated that, in the opinion of the Board of Directors of the Company, no "reportable event" as defined in National Instrument 51-102 ("NI 51-102") had occurred during the period commencing at the beginning of the Company's two most recently completed financial years and ending on the resignation date. MGO stated that it had no basis to agree or disagree with statements not relating to MGO.

To facilitate its listing on the New York Stock Exchange, in June, 2026, the Company announced that it had entered into several agreements to facilitate the deconsolidation of its former indirect wholly owned subsidiary, Glass House Retail, LLC, segregating the Company's dual-use cannabis business from its medical cannabis business. Before it was asked to resign as GLAS' auditor, and as part of its Q2 2026 interim review, MGO reviewed the Company’s accounting for the deconsolidation transaction and completed its review without identifying any material modification required to the Company’s accounting treatment or related disclosures.

Glass House decided to change auditor based on BDO's expertise and its stated ability to meet Glass House's Q3 reporting deadline of November 16, 2026.

In mid-October 2026, the Company became concerned that BDO might not be able to complete its review procedures on the Company’s third quarter interim financial statements by the applicable reporting deadline. In particular, BDO advised the Company that it had not completed its evaluation of the accounting for the deconsolidation transaction and had not reached a conclusion regarding that matter.

The accounting treatment for the deconsolidation transaction had previously been reviewed by MGO in connection with the Company’s Q2 2026 interim reporting, and MGO completed its Q2 review without identifying any material modification required to that accounting treatment.

In response, the Company contacted MGO regarding its availability and ability to complete the Q3 review within the Company’s reporting timetable. MGO indicated that, subject to completion of its acceptance procedures, formal appointment and completion of its review procedures, it expected to be able to complete the Q3 review within the applicable filing timetable. The Company subsequently decided to reappoint MGO as its auditor.

The Board of Directors concluded that no reportable event occurred during BDO’s tenure. BDO advised the Company, however, that because BDO had not completed its review of the Company’s accounting for the deconsolidation transaction and had not reached a conclusion regarding that matter before its resignation, BDO considered the matter to constitute an “unresolved issue” and therefore a “reportable event” under NI 51-102. The Company disagrees with BDO’s characterization but is disclosing BDO’s position in accordance with NI 51-102.

BDO did not issue an auditor's report on the Company's financial statements during its appointment.
