In 2022, the Board of Directors decided to initiate a tender for the audit and related services of Lonza Group Ltd and its subsidiaries starting from the financial year 2024. The overall objective of the audit tender was to select the best auditor in terms of quality within a competitive price range through a non-discriminatory, transparent and robust selection process, in line with good governance practices. The tender was open to any audit firm having sufficient expertise, experience, IT capabilities and geographical footprint to audit a listed company with a global scale and high complexity of operations. The Board of Directors proposed to Lonza’s shareholders Deloitte AG as its external auditor effective from the financial year 2024.
