Arcadia Biosciences, Inc. – Changes in Certifying Accountant

Arcadia Biosciences, Inc. has dismissed Deloitte & Touche LLP as its independent registered public accounting firm, effective March 30, 2026. The dismissal was approved by the company's audit committee. Deloitte's audit reports for the years ended December 31, 2025, and 2024, did not contain adverse opinions or disclaimers, but did include an explanatory paragraph regarding the company's ability to continue as a going concern due to accumulated deficit, recurring net losses, and insufficient cash resources. The company identified material weaknesses in internal control over financial reporting for the year ended December 31, 2025, related to insufficient segregation of duties and inadequate information system controls, partly due to employee headcount reduction. Deloitte has been authorized to respond to inquiries from the successor accounting firm. Concurrently, the audit committee approved the engagement of Ramirez Jimenez International CPAs (RJI) as the new independent registered public accounting firm, effective immediately. RJI will be responsible for the financial statements for the quarter ending March 31, 2026, and the audit for the year ending December 31, 2026. The company stated that it had not consulted RJI on any accounting or auditing matters prior to their engagement.
