# Arcadia Biosciences dismisses Deloitte, hires RJI as new auditor; cites material weaknesses

## Summary
- Dismissed Deloitte & Touche on March 30, 2026; engaged Ramirez Jimenez International CPAs (RJI) same day.
- Deloitte's reports for 2024-2025 included going concern doubt due to accumulated deficit and recurring net losses.
- No disagreements with Deloitte, but material weaknesses in internal controls (segregation of duties, IT controls) existed as of Dec 31, 2025.
- RJI will handle Q1 2026 review and FY 2026 audit; no prior consultations with RJI on accounting matters.
