- Affirmed
“The financial statements have been prepared on a going concern basis. The Directors have prepared forecasts to June 2027, including cash flow projections, which demonstrate that, taking account of potential and realistic changes in trading performance, the Group will have sufficient funds to continue to meet its liabilities as they fall due for at least 12 months from the date of approval of the financial statements. Having considered the working capital of the business, the Directors are satisfied that it is sufficient for its needs and therefore continue to adopt the going concern basis in their preparation of the financial statements.”

Significant events
- “Investment in Research & Development remains core to the business' ongoing success. This year marks the first two orders for the newly-developed Ebflow product and development of the Evflow product continues to look promising. Orders have been received for two Ebflow machines as part of the renaissance of interest in the nuclear power industry, especially SMRs. Similarly, the launch of Evflow is helping to increase the performance of electric motors in the automotive industry, and the first order for this new product had been received by the date these accounts were signed.”
