The pre-rename distress is substantial: by January 2024 a delayed automotive project pushed roughly GBP 2.7 million of revenue out of FY2023; ROX Equity Partners provided GBP 2.9 million of convertible loans then subscribed GBP 5.6 million at 10 pence per share, cleared under the NSI Act on 2024-06-10; FY2023 results showed a pretax loss widening to GBP 18.0 million from a restated GBP 6.4 million, with shares down 96 percent; shareholders voted 2024-08-12 to cancel the AIM admission and re-register as private, effective 2024-08-21. The rebrand to Aion Silicon followed 2025-04-23 under CEO Oliver Jones, repositioned around foundry-neutral, IP-agnostic front-end SoC architecture for AI-centric silicon, with 120-plus engineers across four design centres and hundreds of tapeouts of heritage.
