Audit opinion
Unqualified (clean)
Going concern
Affirmed

“The company's ultimate parent company, Abbott Laboratories, has provided the director of the company with a letter of support stating that they will assist the company in meeting its liabilities as and when they fall due for a period of 12 months from the date of approval of the financial statements for the year ended 31 December 2025. The director has no reason to believe that a material uncertainty exists that may cast significant doubt on the ability of Abbott Laboratories to honour the letter of ongoing financial support. Accordingly, the company continues to adopt the going concern basis in preparing the financial statements.”
