“The financial statements have been prepared under the going concern basis as the directors have undertaken a review of the future financing requirements for the ongoing operations of the Company and the wider Group including the Group support available to the Company and are satisfied that sufficient cash facilities are secured, in respect of positive cash inflows from operations, to meet its working capital requirement for at least 12 months from the date of signing the financial statements. The Company is profitable and has positive net assets. The directors accordingly consider it appropriate for the financial statements to be prepared on a going concern basis.”
Significant events
- “Recovery in memory chip demand, especially on Al/Data Center application attributed to remarkable turnaround in the semiconductor market compared to 2023. Strong demand from Al Infrastructure spiked the needs of high density DRAM and NAND which contributed to an increase in average selling price for both DRAM and NAND products.”

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
