2 \| Invitation to the Annual General Meeting 2026 Dear Shareholders, It is my pleasure to invite you to the Annual General Meeting ("General Meeting") of Sunrise Communications AG ("Sunrise"). Telecommunications services are the digital backbone of our society. Reliable, high-performance networks are essential to economic competitiveness, innovation and social participation. With accelerating digitalisation and advances in artificial intelligence, their importance continues to grow. As Switzerland's premium challenger, Sunrise bears a clear responsibility to help shape the market and to create long-term value for its shareholders. With around 2,900 employees, Sunrise focuses on strong customer relationships, a worldclass network and disciplined capital allocation, serving a customer base with approximately 5.4 million user connections. Despite a challenging market environment, Sunrise delivered on its financial guidance for the 2025 financial year. Stable operating performance, systematic cost management and lower capital intensity supported a solid increase in cash generation. This enables the Board of Directors to propose a progressive dividend while maintaining a resilient balance sheet. The year was also marked by important strategic and commercial progress. Sunrise strengthened its premium portfolio, sharpened its multi-brand approach and expanded its offering for consumers as well as enterprise and SME customers. At the same time, the nationwide rollout of the 5G Standalone network was completed, further reinforcing Sunrise position as a provider of outstanding mobile and fixed connectivity for businesses and consumers in Switzerland. On top of that, sustainability remains an integral part of our strategy. Sunrise took further steps with an SBTi validated net zero target and a transition plan, strengthened supplier engagement and deepened employee involvement in social initiatives. Comprehensive external recognition through important ratings confirms the successful path. Looking ahead to the business year 2026, Sunrise sees itself well positioned to continue delivering value – based on our clear focus on long-term customer relationships, a modern network platform, and a strong emphasis on cash generation. On behalf of the Board of Directors, I would like to thank our shareholders for their continued trust and support. I look forward to welcoming you at the General Meeting. Best regards, Mike Fries Chairman of the Board of Directors

The proposed maximum aggregate amount is comprised of the following components: • Gross base salaries, estimated pension and social security contributions (excluding employer social security contributions) to be paid (or expected to be paid) by Sunrise pursuant to applicable pension plans and laws and fringe benefits including car allowance and relocation/housing/schooling allowances amounting to CHF 5.5 million in the aggregate. • Performance-related annual bonuses under the annual Short Term Incentive Plan (STIP).

Members of the Executive Committee may receive up to 100% of their earned annual bonus 2027 in the form of Class A Shares in 2028. In 2028, Sunrise plans to grant the SHIP 2027 participants additional RSUs equal to 12.5% of the gross number of Class A Shares they have elected to receive under the SHIP 2027.
