Ad hoc announcement pursuant to Art. 53 LR Baloise Group 2022 Annual Report published

Basel, 28 March 2023. Following the publication of the preliminary financial results on 9 March 2023, the Baloise Group 2022 Annual Report is now available to download or to order. Baloise has also published its Annual Review, a report that provides a comprehensive overview of value creation at Baloise and contains elements of the non-financial reporting.

This year, we are again publishing our Annual Review, in addition to the Annual Report, to show how Baloise is upholding its responsibility as a corporate citizen to customers, employees and investors. The report forms the basis for the Company’s non-financial reporting and anticipates the future direction of disclosure requirements in Switzerland and the EU. The Annual Review covers the business strategy and business model and includes in-depth information about what the Baloise Group has been doing in 2022. It also outlines the economic, social and environmental impact of Baloise’s activities. The non-financial information has been expanded on this year and is already geared towards future mandatory disclosure requirements in Europe and Switzerland. We are also using the Annual Review to report for the first time on our sustainability criteria in underwriting, thus putting into practice the Principles for Sustainable Insurance. The aim is to position Baloise as a reliable and sustainable partner for finance-related matters. All in all, the Annual Review provides a rounded overview of the value creation model at Baloise.

Information on corporate governance can be found in the Annual Report, which also includes the management report detailing how the business has performed, the remuneration report and the financial report.
