| 8/11/2026 | Rating revision: Rating 4 → Rating 3 AI review | The company has demonstrated a notable increase in revenue and a growing contract backlog, which signals early commercial validation of its technology. While the firm remains loss-making and continues to face significant execution risks, this progress warrants moving the rating from 4 to 3 to reflect improved speculative potential. A rating of 3 is appropriate given the transition from pure R&D to tangible revenue generation. |
