André Krause, CEO of Sunrise, says: «We were able to accelerate our customer growth and achieved very strong net growth in mobile postpaid customers and growth in Internet customers for the fourth consecutive quarter. Growth was supported by attractive offers for new and existing customers and a continuing increase in customer loyalty. The financial results are in line with expectations and we continue to confirm our updated guidance for 2024 in full, with the payment of a dividend of at least CHF 240 million in mid-2025. The spin-off was approved by the Liberty Global shareholders with more than 99% in favour and is now entering the home stretch. From 15 November, Sunrise will once again begin its journey as a Swiss company listed on SIX.»

Strong customer growth continues

Despite the quieter summer months, Sunrise achieved very strong net growth in Q3 2024 with ca. +48,000 mobile postpaid subscriptions^1^. The growth trend in Internet products was maintained for the fourth consecutive quarter and amounted to roughly +5,000 broadband RGUs. The growth in both areas was supported by increased customer loyalty. The share of broadband customers using a Sunrise mobile offer also saw positive development. This fixed-mobile-convergence (FMC^2^) penetration rose by +1.1 percentage points to 56.6% year-on-year. As of 30 September 2024, Sunrise had 3.097 million mobile RGUs, 1.312 million broadband Internet RGUs and 0.986 million enhanced TV RGUs.

By cross- and upselling convergent products and complementary services, such as those for entertainment, hardware and cybersecurity, Sunrise is continuing to drive growth in its customer base.

New offers support growth

Since August 2024, Sunrise has been offering customers who have previously had an Internet speed of 1 Gbit/s a new maximum Internet speed of 2.5 Gbit/s, both on the fibre network (FTTH) and the hybrid fibre-optic cable network (HFC). Sunrise has thereby more than doubled the speed. Together with its HFC partner networks, Sunrise reaches all the regions of Switzerland and is using its speed upgrade to strengthen its position as Switzerland’s leading broadband Internet provider ^5^: Sunrise is the only provider offering gigabit speeds to almost every household, either via fibre-optic offers (up to 10 Gbit/s), the HFC network (up to 2.5 Gbit/s) or the 5G network («fixed wireless access» [FWA] with up to 1 Gbit/s), further supporting customer satisfaction and loyalty. The company’s own HFC network (and FWA) continued to enjoy a large share, at 55%, of new broadband Internet subscriptions in Q3 2024.

Sunrise launched its «Device as a Service» strategy two years ago. Since then, smartphone purchase and ownership has been offered as a service. With the «Flex Premium Bundle», Sunrise has put together individual components into a new all-in-one package. The Flex Premium Bundle combines the purchase of the device with instalment payments and the option either to exchange the device for a new one at any time, or to have it repaired at any time giving it the improved sustainability that circularity brings. Around 50% of the iPhones sold by Sunrise are sold with the «Flex Upgrade» option.

After leading the way in the market with a dedicated mobile private network (MPN) solution, Sunrise Business now offers innovative 5G solutions withMPN slicing**,** based on the 5G Standalone (SA) standard. For MPN slicing, parts of the public 5G network are split into private, virtually isolated segments. In this way, enterprise customers can take advantage of defined speeds, latency times and capacities, along with increased security and network availability.

In Q3 2024, Sunrise Business was once again able to mark prestigious customer successes and agree numerous new contracts and contract renewals/upgrades with companies such as FC Basel 1893 and Sauber Motorsport.

Stable financial result

The Q3 2024 financial results were in line with expectations. Sunrise generated revenue of CHF 749.0 million, which corresponds to a moderate decline of -1.3% compared to the same quarter of the previous year. The continued growth momentum of the business-customer segment and of yallo in the secondary-brand business (Flanker Brands) had a positive effect. It was achieved through increasing Internet- and mobile-subscription revenues, driven by customer growth and higher migration from prepaid to postpaid^1^ subscriptions.

Overall, revenue in the residential customer segment declined to CHF 538.6 million (-4.4% YoY). The decline in revenue was mainly due to the phasing out of rightpricing in the existing customer base with the migration of customers from UPC to Sunrise offers. Lower roaming revenues due to seasonal effects and an increase in included services also impacted revenues in the residential segment.

Revenue in the business-customer and wholesale segment reached CHF 207.3 million, representing robust growth of +6.8% YoY. Growth was driven primarily by increasing Internet- and mobile-subscription revenue, including strong performance by the MVNO business within wholesale.

Adjusted EBITDAaL remained stable in Q3 2024 compared to the same quarter of the prior year at 0.4% and reached CHF 274.4 million. The impact of the revenue decline on Adjusted EBITDAaL was mitigated primarily by lower direct costs (phasing) and optimised OPEX spending as a result of the efficiency programme. This led overall to low single-digit growth on an annual basis year-on-year.

Adjusted EBITDAaL less P&E additions recorded accelerated growth of +15.9% YoY in Q3 2024, reaching CHF 163.1 million. The increase is primarily due to lower capital expenditure (CAPEX^4^), which was driven by lower hardware costs for customer devices and lower network and IT expenses including decreasing «costs to capture». In Q3 2024, Sunrise made value-enhancing investments totalling CHF 111.3 million (-16.1% YoY) in networks, product innovations and digital services. These investments accounted for 14.9% of revenue in Q3 2024.

Adjusted FCF developed positively compared to the same period of the prior year and reached CHF 6.2 million. However, due to a one-off effect in Q3 2023, comparability is limited. Semi-annual interest and higher supplier payments impacted Q1 and Q3, with the result that Q2 and Q4 tend to be the strongest cash-flow-generating quarters.

Spin-off preparations according to plan

Preparations for the spin-off are going according to plan. The spin-off was approved by the Liberty Global shareholders at the Extraordinary Shareholders’ Meeting on 25 October 2024 with more than 99% of the votes submitted. On 31 October 2024, a CHF 1.2 billion reduction in debt will be made by capital injection from Liberty Global. With the adjusted FCF generated by Sunrise, the reduction in net debt is expected to reach a total of CHF 1.5 billion and the net debt ratio to fall to 4.5x by the end of the year. Sunrise confirms its expected net debt ratio of 3.5 – 4.5 in the medium term and intends to use adjusted FCF surpluses for further debt reduction as part of its capital allocation.

The next steps in November 2024 for the spin-off are:

04.11. Record date for the Liberty Global common shares that are registered for the distribution and bear an entitlement to Sunrise shares of the corresponding class in the form of American depositary shares (ADS) on the effective date of<br>the spin-off based on the corresponding distribution ratio
12.11. Issuance of Sunrise shares to Liberty Global shareholders in the form of Sunrise ADS
13.11. First standard trading day of the Sunrise Class A ADS on the Nasdaq
14.11. Start of the option to exchange Sunrise ADS for underlying Sunrise shares
15.11. Listing and first day of trading of Sunrise Class A shares on the SIX Swiss Exchange
22.11. Expected inclusion of Sunrise Class A shares in the Swiss Performance Index (SPI)
^1^ Net Additions incl. Residential and B2B; Q3 2023 Postpaid net additions adjusted versus Factsheet by a shift of<br>27,000 from non-organic Prepaid to Postpaid related to swype (within Flanker Brands).

^2^ Fixed-mobile convergence represents the number of customers who subscribe to both a fixed broadband Internet<br>service and pre- or postpaid mobile telephony service, divided by the total number of customers who subscribe to fixed broadband Internet service.
--- ---
^3^ Quantitative reconciliations to net earnings/loss (including net earnings/loss growth rates) and to cash flow<br>from operating activities for the Adj. EBITDA, Adj. EBITDAaL, and Adj. FCF forecasts cannot be provided without unreasonable efforts as we do not forecast (i) certain non-cash charges including: the<br>components of non-operating income/expense, depreciation, amortisation and impairment, restructuring and other operating items included in net earnings/loss from continuing operations, nor (ii) specific<br>changes in working capital that impact cash flows from operating activities. The items we do not forecast may vary significantly from period to period, subject to unforeseen events.
--- ---
^4^ Less additions from lease costs and ice-hockey rights.<br>
--- ---
^5^ The Sunrise HFC network has approximately 60% geographical coverage in Switzerland and is the largest network<br>offering 1 gigabit per second (Gbit/s) or higher speeds in Switzerland. It is also the largest HFC network in Switzerland by coverage.
--- ---
^6^ The updated guidance range under US GAAP and IFRS is CHF 360 million to CHF 370 million,<br>including an estimated CHF 10 million of one-off costs, assuming for both items that the spin-off transaction occurs.

Non-IFRS Financial Measures^^

This press release includes financial measures not presented in accordance with International Financial Reporting Standards (IFRS), including Adjusted EBITDA, Adjusted EBITDAaL, Adjusted EBITDAaL less P&E Additions, and Adjusted FCF.

Adjusted EBITDA: Adjusted EBITDA is defined as net income (loss) before income tax benefit (expense), share of losses (gains) of affiliates, financial income, financial expenses, depreciation and amortization, share-based compensation expense, and impairment, restructuring and other operating items. Other operating items include (a) provisions and provision releases related to significant litigation, (b) certain related-party charges and (c) gains and losses on the disposition of long-lived assets.

Adjusted EBITDAaL: Adjusted EBITDAaL is defined as Adjusted EBITDA after lease-related expenses.

Sunrise believes Adjusted EBITDA and Adjusted EBITDAaL are meaningful measures because they represent a transparent view of Sunrise’s recurring operating performance that is unaffected by its capital structure and allows management to (a) readily view operating trends, (b) perform analytical comparisons and benchmarking between segments and (c) identify strategies to improve operating performance. Sunrise believes Adjusted EBITDA and Adjusted EBITDAaL are useful to investors because they provide a basis for comparing Sunrise performance with the performance of other companies in the same or similar industries.

Adjusted EBITDAaL less P&E Additions: Adjusted EBITDAaL less P&E Additions is defined as Adjusted EBITDAaL less property and equipment additions on an accrual basis (excluding those P&E additions under finance lease). Adjusted EBITDAaL less P&E Additions is a meaningful measure because it provides (i) a transparent view of Adjusted EBITDAaL that remains after capital spend, which Sunrise believes is important to take into account when evaluating overall performance and (ii) a comparable view of Sunrise performance relative to other telecommunications companies.

Adjusted Free Cash Flow: Adjusted FCF is defined as net cash provided by operating activities, plus (a) operating-related vendor financed additions (which represents an increase in the period to actual cash available as a result of extending vendor payment terms beyond normal payment terms, which are typically 90 days or less, through non-cash financing activities), and (b) cash receipts in the period from interest-related derivatives, less (i) cash payments in the period for interest, (ii) cash payments in the period for capital expenditures, (iii) principal payments on amounts financed by vendors and intermediaries (which represents a decrease in the period to actual cash available as a result of paying amounts to vendors and intermediaries where we previously had extended vendor payments beyond the normal payment terms), and (iv) principal payments on lease liabilities (which represents a decrease in the period to actual cash available). Sunrise believes its presentation of Adjusted FCF provides useful information to investors because this measure can be used to gauge its ability to (i) service debt and (ii) fund new investment opportunities after consideration of all actual cash payments related to its working capital activities and expenses that are capital in nature, whether paid inside normal vendor payment terms or paid later outside normal vendor payment terms (in which case payment is typically made in less than 365 days). Adjusted FCF should not be understood to represent Sunrise’s ability to fund discretionary amounts, as they have various mandatory and contractual obligations, including debt repayments, that are not deducted to arrive at these amounts.

These non-IFRS financial measures should be viewed as supplements to, and not substitutes for, IFRS measures of performance or liquidity as presented in Sunrise’s IFRS financial statements. These non-IFRS financial measures have no standardized meaning under IFRS and may not be comparable to similarly titled measures reported by other companies. They should not be considered in isolation or as an alternative for or superior to IFRS measures. These measures are presented and described in order to provide additional means of understanding Sunrise’s results in the same manner as its management team.

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 product offered to residential customers. This includes customers who receive discounted services pursuant to a program Sunrise has in place with their employer, small or home office (“SOHO”) customers and small or medium enterprise (“SME”) customers (generally defined as businesses with 99 or fewer employees) and does not include services provided to large enterprises (generally defined as businesses with 100 or more employees) or wholesale services. (3) Business customer and wholesale Mobile RGUs represent the number of active SIM cards in service that are provided to business and wholesale customers, including customers who receive discounted services pursuant to a program Sunrise has in place with their employer, SOHO, SME and large enterprise customers, as well as to customers who subscribed for mobile services delivered over Sunrise’s networks through a branded reseller with whom Sunrise contracts, and excluding customers who subscribed for mobile services delivered over Sunrise’s networks through a MVNO with whom Sunrise contracts, as well as other wholesale customers.

The amortization of all right of use assets is presented as part of depreciation expense under IFRS whereas the amortization of operating leases is presented as part of operating expenses under U.S. GAAP. Interest expense related to the accretion of all lease liabilities is presented as part of interest expense under IFRS whereas the periodic accretion of lease liabilities related to operating leases is recognized as a reduction to amortization expense presented as part of operating expenses under U.S. GAAP. Asset Retirement Obligations: Asset retirement obligation provisions are remeasured at each reporting period and accretion expense on asset retirement obligation provisions is presented as interest expense under IFRS, whereas asset retirement obligation provisions are only remeasured upon a revision of the estimated cash flows and accretion expense is presented within operating expenses under U.S. GAAP. Pension: Curtailment gains are recognized at the same time as the related restructuring or termination benefits under IFRS whereas curtailment gains are recognized when they occur under U.S. GAAP. Cloud Computing: Certain cloud computing costs related to application development that are provided directly by the cloud computing provider and would not be incurred again if the provider were replaced with another provider are allowed to be deferred as a prepayment and expensed over the service period under IFRS. Under U.S. GAAP, eligible costs incurred during application development are allowed to be deferred as a prepayment and expensed over the service period regardless of whether they are provided directly by the cloud computing provider or another party. Sports Rights Agreements: Sports rights agreements are capitalized as an intangible asset and recognized as a liability at the start of the first sports season and subsequently amortized on a straight line basis over the contract term under IFRS, whereas payments for sports rights in advance of the respective season are recorded as a prepaid expense and amortized on a straight-line basis over the respective sports season within operating expenses under U.S. GAAP.

Rebase Information (1) 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.

The revenue, Adjusted EBITDAaL and Adjusted EBITDAaL less P&E additions of EBLT has been reflected in the 2022 and 2021 rebased amounts based on what Sunrise believes to be the most reliable information that is currently available (generally pre-acquisition financial statements), as adjusted for the estimated effects of (a) any significant differences between IFRS and local generally accepted accounting principles, (b) any significant effects of acquisition accounting adjustments, (c) any significant differences between Sunrise accounting policies and those of the EBLT and (d) other items deemed appropriate. Pre-acquisition periods have not been adjusted to eliminate nonrecurring items or to give retroactive effect to any changes in estimates that might be implemented during post-acquisition periods. As Sunrise did not own or operate EBLT during the pre-acquisition periods, no assurance can be given that all necessary adjustments have been identified to present the revenue, Adjusted EBITDAaL and Adjusted EBITDAaL less P&E Additions of EBLT on a basis that is comparable to the corresponding post-acquisition amounts or that the pre-acquisition financial statements relied upon do not contain undetected errors. In addition, the rebased results are not necessarily indicative of the revenue, Adjusted EBITDAaL and Adjusted EBITDAaL less P&E Additions that would have occurred if this transaction had occurred on the date assumed for purposes of calculating rebased amounts or the revenue, Adjusted EBITDAaL and Adjusted EBITDAaL less P&E Additions that will occur in the future. (2) In connection with the completion of UPC Switzerland’s acquisition of Sunrise Communications Group AG on November 11, 2020, the opening balance sheet of the combined business was reported at its estimated fair value. As such, certain amounts were adjusted to reflect the impact of acquisition accounting as required under IFRS, including the write-off of deferred commissions and installation costs (Acquisition Accounting Adjustments). The above adjustments therefore reverse the effect these Acquisition Accounting Adjustments and reflect the amortization of deferred commissions and installation costs to Adjusted EBITDAaL as if these amounts had not been written off in purchase accounting as to not impact the underlying growth rates of the business for this non-organic impact, until such point these deferred commissions and installation costs returned to pre-acquisition run-rate levels. (3) During the first quarter of 2023, Liberty Global changed the terms of certain agreements related to charges for certain products and services that they provide to their reportable segments, including Sunrise. These products and services include CPE hardware and related essential software, maintenance, hosting and other services. As a result, Sunrise now capitalizes the combined cost of the CPE hardware and essential software as property and equipment additions. The other services, including maintenance and hosting, continue to be reported as operating costs in the period incurred (included in Adjusted EBITDAaL). The above adjustments reflect the impact of this change in contract terms in the years ended December 31, 2022 and 2021 to the same extent this change impacted the 2023 results. (4) During the fourth quarter of 2023, Sunrise recongized a gain related to a pension curtailment as a result of certain one-time restructuring activies. The above adjustment reverses the effect of this one-time gain as to not impact the underlying growth rates of the business for this non-organic impact. (5) Represents certain one-time Sunrise Spin-Off related costs. The above adjustment reverses the effect of these one-time costs as to not impact the underlying growth rates of the business for this non-organic impact.
