• The financial results for Q1 2025 remained in line with expectations. The guidance for 2025 is confirmed in full including the expected dividend for financial year 2025⁴ of CHF 3.42 per Class A Share and ~CHF 0.34 per Class B Share in 2026 corresponds to dividend growth of +2.7%.

Consolidated results table for Q1 2025

Note: The key financial figures are presented on a rebased IFRS basis. Alternative definitions of key performance indicators and reconciliations can be found in the appendix of this ad hoc announcement.

«In view of the price increases we announced, we have intentionally reduced our promotional activities. As expected, this led to lower customer growth in Q1. However, the decline in revenue from residential customer subscriptions was slower than in the previous quarter, and we were able to increase slightly our operating profit year-on-year. In Q1, we also laid important milestones for the rest of the year. With the introduction of 5G Standalone, we are continuing to drive innovation forward. The preparations for the new mobile portfolio and significant loyalty benefits are strengthening our strategic focus on long-term customer relationships rather than short-term acquisition. We therefore confirm our 2025 guidance in full, including the targeted dividend growth», said André Krause, CEO of Sunrise.

Continued customer growth and increased customer loyalty

Sunrise recorded continued net customer growth in Q1 2025, with +12,000 mobile postpaid RGUs (revenue generating units) and +5,000 broadband Internet RGUs. The slower growth compared to the same period last year is primarily attributable to spillover effects from the fourth quarter of 2024 and to deliberately reduced promotional activities in light of the price increases in Q1 2025.

Strong momentum in the B2B broadband segment was offset by a lower inflow in the B2B mobile segment. The migration of UPC customers to Sunrise products, which is in its final phase and is expected to be completed by the middle of the year, also had an impact.

This growth was supported by a further increase in customer loyalty. Churn has been reduced again. With the launch preparation of the new «Swiss Connect» mobile portfolio in Q1 2025, Sunrise continued to execute consistently its focus on customer loyalty and on the development of customer relationships.

With the introduction of 5G Standalone (5G SA), Sunrise is the only network operator to offer a nationwide 5G SA mobile network in Europe, once again leading the way as a pioneer. While the first customers are enjoying the benefits of 5G SA, the certification of more devices and offers tailored to private and business customers are planned for the coming quarters.

The price adjustments and the milestones achieved in Q1 2025 are expected to have a positive commercial impact in the following quarters.

Further increase in FMC⁶ rate

The proportion of broadband customers who also use a Sunrise mobile postpaid offer continued to develop positively. The fixed-mobile convergence rate (FMC⁶) increased by 1.5 percentage points YoY to 58.3%. As of 31 March 2025, Sunrise had around 3.13 million mobile, 1.30 million broadband Internet and approx. 1.0 million enhanced TV RGUs.

Solid financial result for Q1 2025

Revenue declined in Q1 2025 (-3.3% YoY), amounting to CHF 722.1 million. Revenue was affected by lower device sales resulting from weaker demand for newly launched mobile phones and the reduction of TV gifting volumes bundled with broadband subscriptions. The effect was only partially offset by continued customer growth. Furthermore, the ongoing right-pricing within the customer base also had an impact.

Adjusted EBITDAaL² increased slightly in Q1 2025 by +0.4% YoY and reached CHF 240.0 million. The positive development of adjusted EBITDAaL² was supported by slightly lower operating costs. This was driven by a combination of the continuously improving cost efficiency and the phasing of certain expenses such as marketing-campaign spend.

Adjusted EBITDAaL² less P&E Additions (CAPEX³) declined by -10.7% in Q1 2025, reaching CHF 96.9 million. The decline is primarily due to frontloaded investments in the network and in equipment used for customer Internet access (customer premises equipment, CPE). Investments (CAPEX³) increased by +9.5% YoY, reaching CHF 143.1 million in Q1 2025, which represents 19.8% of revenue.

Adjusted FCF² decreased to CHF -116.5 million in Q1 2025. Alongside increased investments (CAPEX³), semi-annual interest and higher supplier payments, typically incurring in the first and third quarters, had an impact, so that the second quarter and particularly the fourth quarter are most significant for generating the expected cash flow.

Confirmed guidance for the 2025 financial year:

• Revenue growth: broadly stable

• Adjusted EBITDAaL²: Stable to low-single-digit growth

• CAPEX/revenue: 15–16% of revenue

• Adjusted FCF²:^{CHF 370–390 million7}

• Expected dividend payout for financial year 2025 of CHF 3.42 per Class A Share and ~CHF 0.34 per Class B Share in 2026 in line with targeted progressive dividend-per-share policy (+2.7% YoY).⁴

The dividend will be exclusively paid out of reserves from foreign capital contributions and hence treated as a repayment of qualifying additional paid-in capital for Swiss tax purposes. Accordingly, the expected dividend for the financial year 2025 will not be subject to Swiss withholding tax of 35%.⁵ For Swiss resident individuals holding the shares as private assets, the dividend is in principle not subject to Swiss income tax. The amount of reserves from foreign capital contributions remaining after the financial year 2024 dividend payment is approx. CHF 2.58 billion⁵.

Delisting of Sunrise Class A ADSs on Nasdaq scheduled for August 2025

Consistent with the plan announced in connection with the spin-off of Sunrise from Liberty Global last year that the Nasdaq listing of the Sunrise Class A American Depositary Shares (ADSs) under the ticker «SNRE» would be only for a transitional period of approximately nine months to facilitate initial holding and trading, the Sunrise Board of Directors has decided to delist the Class A ADSs from Nasdaq in mid-August 2025. Following the delisting of the Class A ADSs from Nasdaq, Sunrise also plans to terminate the sponsored ADS program for both the Class A and Class B ADSs.

Sunrise Class A shares will remain listed on SIX Swiss Exchange under the ticker «SUNN». 

Sunrise ADS holders have been entitled to cancel their Sunrise ADSs and withdraw the underlying Sunrise shares since 14 November 2024. As of 15 May 2025, approximately 82% of the Class A ADSs and 98% of the Class B ADSs (which are not listed on any stock exchange and are tradable only over-the-counter (OTC)) have, on a net basis, been cancelled against delivery of the underlying Sunrise shares. At the same time, trading volumes progressively transitioned to SIX Swiss Exchange, with Switzerland accounting for the majority of trading in Sunrise shares since March 2025.

Sunrise expects that eliminating the Nasdaq listing and sponsored ADS programs will streamline regulatory reporting processes and save costs. The U.S. is not the primary trading market for Sunrise Class A shares, and the Nasdaq listing was always intended to be temporary.

The last trading day of the Class A ADSs on Nasdaq is expected to occur in mid-August 2025. Sunrise will provide a notice of voluntary delisting to Nasdaq and the market in accordance with the rules of the Nasdaq and the U.S. Securities and Exchange Commission closer to the intended effective date of delisting. Once the delisting is effective, the remaining Class A ADSs will no longer be traded on Nasdaq but may continue to trade in the U.S. OTC market. The termination of the sponsored Class A and Class B ADS programs is expected to take place within 90 days following the last day of Class A ADS trading on Nasdaq. Holders of Sunrise Class A and Class B ADSs will be notified of the exact termination date closer to the time, but should already now start planning to manage their holdings and brokerage accounts accordingly.

After the delisting of the Class A ADSs from Nasdaq, Sunrise intends to deregister its Class A and Class B ADSs under the U.S. Securities Exchange Act of 1934 and terminate its reporting obligations thereunder as soon as it is permitted to do so.
