- Unqualified (clean)
- Going concern
- Affirmed
“In auditing the financial statements, we have concluded that the 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 ability to continue as a going concern for a period of at least twelve months from when the financial statements are authorised for issue.”

Significant events
- “Supply chain and component availability remain a principal risk for the Group, notwithstanding improvements in lead times during recent periods. The Group continues to hold increased stock levels to mitigate against this risk and maintains close relationships with key suppliers and contract manufacturing partners.”
- “Technology risk remains present as new standards are adopted across the Group's key markets. The Board continues to believe that the Group's ongoing investment in research and development, and its relationships with development and supply partners, position it well to respond to these changes.”
- “Recruitment and retention of skilled engineering and support staff remains a risk given the growth in the Group's customer base, and the Group continues to work with recruitment partners to secure appropriately skilled personnel.”
- “The Group operates internationally, including through subsidiaries in Italy and Poland, and is therefore exposed to foreign currency risk, as reflected in the movement on the Group's foreign exchange reserve during the year. Directors confirm that increased risk because of geographical revenue shift has been mitigated with favourable banking and treasury policies.”
