Lonza’s Board of Directors is proposing a dividend for shareholders of CHF 4.00 per share for 2023. The proposal represents a payout of 44% of 2023 reported profit for the period of Lonza Group. Subject to approval at the upcoming Annual General Meeting (AGM) on 8 May 2024, 50% of the dividend of CHF 4.00 per share will be paid out of the capital contribution reserve and will therefore be free from Swiss withholding tax.
