Operating performance improved modestly, with Adjusted EBITDAaL up 2.5% to CHF 245.9 million . However, net income deteriorated from a CHF 1.3 million loss to a CHF 39.4 million loss , driven largely by higher net financial expenses and restructuring-related items.

Rhea-AI Filing Summary

Sunrise Communications reported Q1 2026 revenue of CHF 722.8m, essentially flat year over year, while Adjusted EBITDAaL rose 2.5% to CHF 245.9m, showing slightly stronger operating profitability. Net loss widened to CHF 39.4m from CHF 1.3m, mainly from lower financial income and higher restructuring costs.

P&E Additions (CAPEX) fell to CHF 133.6m, aiding a 15.9% increase in Adjusted EBITDAaL less CAPEX to CHF 112.3m. Adjusted Free Cash Flow remained negative at CHF -111.0m, broadly similar to the prior year’s seasonal pattern. Management fully reconfirmed 2026 guidance, including Adjusted EBITDAaL of about CHF 1bn and Adjusted FCF of CHF 380–400m.

The company highlighted strategic initiatives such as the launch of the Sunrise Rewards loyalty program, an exclusive B2B AI partnership with PHOENIQS, and a price increase effective 1 August 2026. For FY 2025, a dividend of CHF 3.42 per Class A share and CHF 0.34 per Class B share has been paid, with an expected FY 2026 dividend of CHF 3.49 and CHF 0.35 respectively, funded from reserves from foreign capital contributions and therefore not subject to Swiss withholding tax.

Insights

Solid Q1 operations with flat revenue, higher margins, but a larger accounting loss and still-negative cash flow.

Sunrise delivered Q1 2026 revenue of CHF 722.8m, up only 0.1% year over year, but lifted Adjusted EBITDAaL by 2.5% to CHF 245.9m through cost optimization and organizational changes. Adjusted EBITDAaL less P&E Additions increased 15.9%, indicating better cash-like profitability after investment.

The headline net loss widened to CHF 39.4m from CHF 1.3m, driven by a swing in net financial expense to CHF 65.5m and higher restructuring and other operating items of CHF 27.5m. These factors are largely non-operational, while operating income ticked up slightly to CHF 13.4m.

Adjusted Free Cash Flow stayed negative at CHF -111.0m, reflecting semi-annual interest payments, vendor-financing dynamics and working-capital seasonality. Gross debt was CHF 4.892bn and net debt CHF 4.740bn, with a weighted average cost of debt of 2.7%. Management’s full reaffirmation of 2026 guidance, alongside a tax-efficient dividend and initiatives such as the Sunrise Rewards program and PHOENIQS AI partnership, suggests continuity in the medium-term plan despite near-term cash-flow pressure.

Adjusted free cash flow is the amount of money a company generates from its operations after accounting for essential expenses and investments, like maintaining or upgrading equipment.

forward-looking statements regulatory

"This presentation contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995"

Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.

Non-IFRS financial measures financial

"This presentation includes financial measures not presented in accordance with International Financial Reporting Standards (IFRS), including Adjusted EBITDA"

Non-IFRS financial measures are company-reported numbers that modify or exclude items from standard accounting results so management can highlight what it sees as underlying business performance—common examples are adjusted EBITDA or adjusted earnings per share. They matter to investors because they can make trends clearer by removing unusual or noncash items, like cleaning lens smudges off a camera, but they require scrutiny since companies decide what to exclude and comparisons across firms may not be uniform.

«Our commercial result is in line with expectations for the first quarter, reflecting the lower market liquidity that is usual for the season. Stable revenue, combined with continued cost discipline, resulted in an improved Adjusted EBITDAaL. With Sunrise Rewards and the recently agreed partnership with PHOENIQS, we have laid important foundations in both the residential and business segments to strengthen commercial momentum over the year. We therefore fully confirm our 2026 guidance, including the targeted dividend growth», commented André Krause, CEO of Sunrise, on the Q1 2026 results.

Growth in mobile postpaid¹, with increasing stabilisation in the Internet² segment

In a seasonally weaker market Sunrise achieved growth in customer numbers at the start of the year in the mobile postpaid¹ segment, with net growth amounting to +10,000 RGUs (revenue generating units). At the same time, the Internet² segment showed an increasing trend to stabilisation compared with the two preceding quarters (-1,000 RGUs compared with -2,000 in Q4 and -7,000 in Q3 2025), which is mainly attributable to stronger customer loyalty and the associated improvement in the churn rate.

The proportion of broadband customers who also used a Sunrise postpaid mobile plan showed continued growth, thanks to continued successful cross-selling. The fixed-mobile convergence rate (FMC⁷) rose by 2.2 percentage points YoY to 60.5%. As of 31 March 2026, Sunrise had around 3.16 million mobile, 1.28 million Internet and 0.96 million enhanced TV RGUs.

Foundations laid for growth in the current year

With Sunrise Rewards, Sunrise launched an innovative loyalty programme in Q1 2026, which is a central component of the customer-focused strategy of the main brand Sunrise. The programme has been systematically and permanently embedded in the customer relationship and is expected to increase loyalty, broaden product usage and foster closer customer relationships through regular interaction, thanks to the loyalty points that can be collected. The aim is to strengthen customer retention in the long term, reduce churn and further promote cross- and upselling within the existing customer base. Following a successful silent launch in March, Sunrise Rewards will be rolled out fully in the coming days and promoted with a major campaign.

Sunrise also dominated the «connect complete check 2026», with the best overall package comprising network quality, premium support, mobile subscriptions and additional services, making it the test winner in six out of seven user profiles. Sunrise was the only provider to receive the top rating of «outstanding» across all user segments assessed, thereby further consolidating its strong position in the premium segment and demonstrating its appeal for a wide range of user needs.

In the B2B segment in Q1 2026, Sunrise initiated an exclusive strategic partnership with PHOENIQS. With this partnership, Sunrise will be the only Swiss telecommunications provider able to offer its business customers AI solutions that are developed, hosted and operated entirely in Switzerland – with no reliance on foreign cloud services. The offer targets large enterprises, the public sector and SMEs, and is specifically designed to meet the requirements of regulated industries.

Solid financial results for Q1 2026

Revenue remained stable in Q1 2026 (+0.1% YoY), primarily due to growth in the mobile postpaid¹ and B2B segments, as well as in device sales. These and other factors offset the decline in the Internet² segment and the generally subdued market liquidity.

Adjusted EBITDAaL³ increased in Q1 2026 (+2.5% YoY). This increase was supported by sustained cost efficiency and the continued optimisation of operating expenses (OPEX). Savings on external IT and professional services had a particularly significant impact and there was a favourable comparison with Q1 2025 due to the varying timing of individual costs. However, it is expected that this phasing effect will even out over the course of the year.

P&E Additions (CAPEX⁴) amounted to 18.5% of revenue in Q1 2026 and fell by -6.6% YoY. The decline is due to the fact that major infrastructure expansions have largely been completed, the investment requirements for network and customer-premise equipment (CPE) expenditure have fallen and efficiency gains have been achieved in IT and project implementations. At the same time, investments were directed specifically towards commercial platforms, products and service innovations.

The increase in Adjusted EBITDAaL³ less P&E Additions (CAPEX⁴) of +15.9% YoY in Q1 2026 derived both from higher Adjusted EBITDAaL³ and from lower CAPEX⁴. The combination of stronger operating results and reduced capital expenditure led to improved operating cash generation. Adjusted FCF^3,5 therefore remained stable in Q1 2026 due to seasonal factors and was in line with the typical cash-flow profile for the first quarter.

2/6

LOGO

The increase in the net loss from CHF 1.3 million in the same quarter of the previous year to CHF 39.4 million in Q1 2026 is primarily due to changes in financial income, in particular the absence of the exchange-rate gains achieved in the same quarter of the previous year, and to higher restructuring costs. Net cash provided by operating activities fell by -41.9% due to working capital movements, driven by lower liabilities and higher accounts receivable, while capital expenditures in the cash-flow statement⁶decreased by -23.3% due to lower expenditure on fixed assets and payments for capital-related provisions that differ in timing.

Financial guidance for 2026 reconfirmed

With its Q1 2026 results, Sunrise has fully reconfirmed its financial guidance for 2026as follows

•

Revenue: broadly stable

•

Adjusted EBITDAaL³: around CHF 1 billion

•

Capital expenditure (CAPEX⁴)/revenue: <15%

•

Adjusted FCF^3,5: CHF 380 – 400 million

•

Expected dividend for the 2026 financial year: CHF 3.49 per Class A Share and CHF 0.35 per Class B Share in 2027, in line with the targeted progressive dividend policy (+>2% YoY).⁹

The expected dividend for the 2026 financial year will be paid exclusively from reserves from foreign capital contributions and will therefore be treated for Swiss tax purposes as a repayment of qualifying additional paid-in capital. Accordingly, the dividend for the 2026 financial year will not be subject to the 35% Swiss withholding tax. For individuals resident in Switzerland who hold the shares as private assets, the dividend is also generally not subject to Swiss income tax. Sunrise expects this tax treatment for dividends to continue in the medium-term future.

¹	Net additions of residential customers and B2B.

Organic net adds of 0k in Q2 2025 and (7k) in Q3 2025 and (2k) in Q4 2025, removal of ~2k / ~3k / ~1k non-organic, non-Revenue generating customers. In Q2/Q3 the removal was part of the Interbrand Migrations, whereas the Q4 correction related to a technical clean up of legacy ADSL lines identified in January 2026 with no underlying customers, billing, or revenues. It has been adjusted in Q4 2025 to maintain comparability of organic trends; Broadband Internet Base RGU development in Q2- Q4 2025 includes the removal resulting in (2k), (3k) and (1k) as per factsheet disclosure.

Quantitative reconciliations to net income/loss (including net income/loss growth rates) and to cash flow from operating activities for the Adjusted EBITDA, Adjusted EBITDAaL and Adjusted FCF forecasts cannot be provided without undue effort, as neither (i) certain non-cash expenses and income, including components of non-operating income/expenses, depreciation and amortisation, and impairment losses, restructuring and other operating items included in net income/loss from continuing operations, nor (ii) specific changes in working capital affecting cash flow from operating activities, are forecast. The items that Sunrise does not forecast may vary significantly from period to period, subject to unforeseen events.

⁴	Excluding finance-lease additions from rental expenses, ice-hockey rights and M&A activity.

⁵

In Q4 2024, Sunrise reached a settlement with the Canton Zurich tax authority regarding a tax audit for years 2019 to 2021 performed during the 2024. The final settlement figure agreed covered fiscal years 2019 to 2024 and amounted to approximately CHF 60m. As a result, Sunrise has recognised significant prior year taxes in the current period, which have been cash settled via amended returns on a cantonal basis largely during 2025, with diminishing phasing over the years 2026 and 2027. Adj. FCF excludes the tax-settlement-related charge and it is not included in the FY 2026 guidance due to pre-funding of the tax settlement by Liberty Global.

⁶	Capital expenditure as part of the net outflow of cash for investing activities («Capital expenditure in cash flows from investing activities»).

⁷	Fixed-mobile convergence indicates the number of residential customers who have subscribed to both a fixed-line broadband Internet service and a postpaid mobile service, divided by the total number of customers who have subscribed to at least one fixed-line broadband Internet service.

⁸	IFRS, on an adjusted basis.

⁹	To be proposed by the Board of Directors of Sunrise upon achieving the financial guidance for the 2026 financial year and subject to approval by the Annual General Meeting.

Non-IFRS Financial Measures

This ad-hoc announcement includes financial measures that are not presented in accordance with International Financial Reporting Standards (IFRS), including Adjusted EBITDA, Adjusted EBITDAaL, Adjusted EBITDAaL less P&E Additions, and Adjusted FCF.

Sunrise believes that Adjusted EBITDA and Adjusted EBITDAaL are meaningful measures because they provide a transparent view of Sunrise’s recurring operating performance, which is unaffected by its capital structure, and allow management to (a) readily identify operating trends, (b) perform analytical comparisons and benchmarking between segments, and (c) identify strategies to improve operating performance.

Sunrise also believes that Adjusted EBITDA and Adjusted EBITDAaL are useful to investors because they provide a basis for comparing Sunrise’s performance with that of other companies in the same or similar industries.

The expected terms of the services are up to five years following the spin-off, depending on the individual service elements. In addition, the transitional service agreements with a five-year term are subject to an early termination right on the fourth anniversary thereof. The aggregate charges expected to be payable by Sunrise under the transitional services agreements will decrease during the term and are approximately CHF 30.0 million for the first year.

Operational KPI’s – Customer relationships Customer Relationships Q125 Q225 2025 (H1) Q325 Q425 2025 Q126 Fixed Customer Relationships represent the number of customers who receive at least one of Sunrise’s broadband internet, TV or fixed-line telephony services, without regard to which or to how many services they subscribe. Fixed Customer Relationships generally are counted on a unique premises basis. Accordingly, if an individual receives Sunrise’s services in two premises o/w Fixed (e.g., a primary home and a vacation home), that individual generally will count as two Fixed Customer Relationships. Sunrise’s fixed customer relationships include customers who receive Basic Cable Services (“BCS”) which are services delivered without the use of encryption-enabling, integrated or virtual technology as well as customers who receive fixed telephony services over Sunrise’s networks, or that Sunrise services through a partner network.

A home, residential multiple dwelling unit or commercial unit may contain one or more RGUs. For example, if a residential customer subscribed to Sunrise’s broadband internet service or enhanced TV service, the customer would constitute two RGUs. RGUs generally are counted on a unique premises basis such that a given premise does not count as more than one RGU for any given service. However, if an individual receives one of Sunrise’s services in two premises (e.g., a primary home and a vacation home), that individual will count as two RGUs for that service. Each bundled internet or enhanced TV service is counted as a separate RGU regardless of the nature of any bundling discount or promotion. Non-paying subscribers are counted as subscribers during their free promotional service period. Some of these subscribers may choose to disconnect after their free service period. Services offered without charge on a long-term basis (e.g., certain preferred subscribers) generally are not counted as RGUs. Free services provided to Sunrise employees generally are counted as RGUs. (2) Business-customer and wholesale fixed relationships and fixed RGUs include customers who receive fixed services that are the same or similar to mass-marketed products offered to residential customers. This includes customers who receive discounted services pursuant to a programme Sunrise has in place with their employer and small business customers (generally defined as businesses with 9 or fewer employees) and does not include services provided to small-medium business customers (generally defined as businesses with 10 to 249 employees) and large enterprises (generally defined as businesses with 250 or more employees) or wholesale services.

Rebase information Rebase Information Rebase results, which are non-IFRS measures, are presented as a basis for assessing growth rates on a comparable basis. Rebase information is provided to show the results of the business without the impact of certain acquisition-related, transaction-related, or certain other amounts that are not organic in nature to the results of the business. As such, rebase results below do not include future transaction specific adjustments, for example, any future incremental costs of Sunrise being a separately listed company or the impact of any future service agreement between Liberty Global and Sunrise, etc. Investors should view rebased results as a supplement to, and not a substitute for, IFRS measures of performance included in Sunrise’s consolidated statements of operations.

When Sunrise pays the financing intermediary, it records financing cash outflows in its consolidated statements of cash flows. For purposes of its Adjusted Free Cash Flow definition, Sunrise (A) adds in the constructive financing cash inflow when the intermediary settles the liability with the vendor as its actual net cash available at that time is not affected and (B) subsequently deducts the related financing cash outflow when Sunrise actually pays the financing intermediary, reflecting the actual reduction to its cash available to service debt or fund new investment opportunities.
