Traders should view this auditor change as a red flag, especially given the combination of going concern uncertainty and repeated material weaknesses. The move from a Big 4 firm (Deloitte) to BDO increases scrutiny risk and may signal deeper financial or governance issues. Monitor for subsequent SEC correspondence from Deloitte and any delays in future filings.
