Annual General Meeting

Sunrise Annual General Meeting: all agenda items approved

At today’s Annual General Meeting of the shareholders of Sunrise Communications AG in Glattpark (Opfikon), all agenda items were approved in line with the proposals of the Board of Directors. The total number of votes, including the votes represented by the Independent Voting Rights Representative, represented 82.36% of the registered stock.

Dividend of CHF 3.33 per Class A Share and CHF 0.33 per Class B Share

The Consolidated Financial Statements for the calendar year 2024, the Annual Financial Statements for the financial year 2024 and the Non-Financial Reporting 2024 were all approved. The shareholders additionally approved the proposal of the Board of Directors to distribute a dividend of CHF 3.33 per Class A Share and CHF 0.33 per Class B Share. The dividend will be paid exclusively from reserves from foreign capital contributions and hence treated as a repayment of qualifying additional paid-in capital for Swiss tax purposes. The dividend for the financial year 2024 will therefore not be subject to Swiss withholding tax of 35%¹. The members of the Board of Directors and the persons entrusted with management were granted discharge for their activities in the financial year 2024.

The Annual General Meeting approved the Compensation Report 2024 in an advisory vote. Furthermore it approved the maximum aggregate amount of compensation of the Board of Directors for the term of office from the 2025 Annual General Meeting to the 2026 Annual General Meeting and the maximum aggregate amount of compensation of the Executive Committee for the financial year 2026.

The shareholders also approved the Board of Directors’ proposal to re-elect Anwaltskanzlei Keller AG as the Independent Voting Rights Representative until the completion of the next Annual General Meeting and the re-election of KPMG AG as the Auditors for the financial year 2025.
