Each % is (latest − prior) ÷ |prior| for the line item as filed. The comparison is only shown when the latest and prior accounts cover broadly equal-length periods — short or long stubs (typical around incorporation or a year-end change) are suppressed rather than misrepresented. Lines a company doesn't report are omitted. About these numbers

- Going concern
- Affirmed
“In auditing the financial statements, we have concluded that the directors' use of the going concern basis of accounting in the preparation of the financial statements is appropriate. Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, individually or collectively, may cast significant doubt on the group's and parent company's ability to continue as a going concern for a period of at least twelve months from when the financial statements are authorised for issue.”
Group structure
- CLINICAL SERVICES INTERNATIONAL LTD · parent
- CSI Clinical Services International GmbH 100%
- Clinical Services International LLC 100%
Significant events
- “CSI launched a new office in Shanghai in Q4 2025 to be the base of their Asian operations.”
- “The business continued to see significant growth via the GmbH subsidiary through a combination of securing new clients conducting major clinical trial studies and maximising revenue from the existing client base through targeted marketing.”
- “CSI continued undeterred and surpassed its major strategic goals for the year. One of the primary goals for the business throughout 2025 was to continue to expand trading activities in the US, via the LLC subsidiary, and the success achieved in this has been a key par. of the group's financial results for the year.”
Auditor, going-concern and subsidiary information is drawn from the narrative of the latest annual accounts. About these numbers
