Key Events

-
Nasdaq Delisting Threat

-
Auditor Non-Reliance on Past Financials
The previous auditor, Grant Thornton, resigned and stated that its audit opinions for 2021-2023 should no longer be relied upon due to governance uncertainties.
-
Significant Net Loss & Cash Burn

Analysis
This 20-F filing for the fiscal year ended December 31, 2025, is a critical update following a Nasdaq delisting notice for late filing. The company's auditor issued an adverse opinion on internal control over financial reporting, citing unresolved governance disputes and ineffective financial reporting controls. This, coupled with the previous auditor's non-reliance on financial statements from 2021-2023, severely undermines investor confidence and highlights significant operational and compliance risks. The ongoing Nasdaq delisting process and complex shareholder litigation further compound the uncertainty surrounding the company's future.
