- Unqualified (clean)
- Going concern
- Affirmed
“The Directors have, at the time of approving the financial statements, considered the applicability of the going concern basis in the preparation of these financial statements. This included a consideration of the company's cash reserves (intercompany loan) and internal forecasts of the financial results. In addition, the Company has received a letter of support from Revvity Inc, their ultimate parent company to ensure financial support is provided going forward, as such, the Directors have a reasonable expectation that the Company has adequate resources to continue in operational existence for the foreseeable future. Thus, they continue to adopt the going concern basis of accounting in preparing the financial statements.”
