# CytoSorbents restates 2023/2024 financials due to inventory and RSU errors

## Summary
- Overstated inventory from clerical error; understated non-cash RSU expense due to using vesting-date fair value instead of grant-date.
- Non-reliance applies to audited FY2023 10-K and unaudited Q1-Q3 2023 and Q1-Q3 2024 quarterly reports.
- Restated financials will be included in the 2024 Annual Report on Form 10-K; prior reports should not be relied upon until then.
- Audit committee and management discussed the errors with the independent registered public accounting firm.
