Forward-Looking Statements This presenation contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, including statements regarding the planned Transaction and its expected benefits, synergies to be achieved by Sunrise, Sunrise’s market share, network, strategy and other information and statements that are not historical fact. These forward-looking statements are based on current expectations, estimates and projections about the factors that may affect Sunrise’s future performance and are subject to certain risks and uncertainties, some of which are beyond the control of Sunrise or Liberty Global, that could cause actual results to differ materially from those expressed or implied by these statements. Such risks and uncertainties include the risk that Liberty Global does not receive shareholder approval for the Transaction and/or related matters, Liberty Global’s ability to satisfy the other conditions to the Transaction on the expected timeframe or at all, the approval of the shares of Sunrise for listing on the SIX Swiss Exchange and the development of a trading market for them, the Liberty Global Board of Directors’ discretion to decide not to complete the Transaction for any reason, Sunrise’s ability to realize the expected benefits from the Transaction, unanticipated difficulties or costs in connection with the Transaction, Sunrise’s ability to successfully operate as an independent public company and maintain its relationships with material counterparties after the Transaction, Sunrise’s ability to successfully execute on its plans and strategies and other factors, including those detailed from time to time in Liberty Global’s filings with the Securities and Exchange Commission (the “SEC”), including its most recently filed annual report on Form 10-K, as it may be supplemented from time to time by its quarterly reports and other subsequent filings. These forward-looking statements speak only as of the date hereof. Although Sunrise and Liberty Global believe that their expectations reflected in any such forward-looking statement are based upon reasonable assumptions, no assurance can be given that these expectations will be achieved. Liberty Global and Sunrise expressly disclaim any obligation or undertaking to disseminate any updates or revisions to any forward-looking statement contained herein to reflect any change in their expectations with regard thereto or any change in events, conditions or circumstances on which any such statement is based. You are cautioned not to place undue reliance on any forward-looking statement. Non-IFRS Financial Measures This presentation includes financial measures not presented in accordance with 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 operating-related vendor financed expenses (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), less (i) cash payments in the period for capital expenditures, (ii) principal payments on operating- and capital-related 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 (iii) principal payments on finance leases (which represents a decrease in the period to actual cash available). Sunrise believes their presentation of Adjusted FCF provides useful information to investors because this measure can be used to gauge their ability to (i) service debt and (ii) fund new investment opportunities after consideration of all actual cash payments related to 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. Use of Projections This presentation contains certain forecasted financial information. The assumptions and estimates underlying such information are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the prospective financial information. The assumptions underlying such information include, among others, successful implementation of revenue stabilization and growth strategies, progress towards realizing the remainder of synergies of the UPC merger and various ongoing operational efficiencies, deleveraging in connection with the spin-off, improved macroeconomic environment, gradual tapering of capital expenditures driven by progress towards completion of key capital initiatives. Accordingly, there can be no assurance that the prospective results are indicative of actual future performance. Inclusion of the prospective financial information in this presentation should not be regarded as a representation by any person that the results contained in the prospective financial information will be achieved. Industry and Market Data This presentation also contains estimates and other statistical data made by third parties and by Sunrise relating to data about Sunrise’s industry. This data involves a number of assumptions and limitations, and you are cautioned not to give undue weight to such estimates. Data generated by third parties has not been verified by Liberty Global or Sunrise. In addition, projections, assumptions, and estimates of the future performance of the markets in which Sunrise operates are necessarily subject to a high degree of uncertainty and risk.

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. Transaction overview Financial Operational Glossary 108 Rebase Information – continued Transaction overview Financial Operational Glossary

109 Rebase Information – continued (1) Represents the pre-acquisition revenue, Adjusted EBITDAaL and Adjusted EBITDAaL less P&E additions of Elektra Baselland Telecom (EBLT), which was acquired by Sunrise during 2023, to the same extent that the revenue, Adjusted EBITDAaL and Adjusted EBITDAaL less P&E additions of EBLT is included in Sunrise results for the year ended December 31, 2023. 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 so 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 recognized a gain related to a pension curtailment as a result of certain one-time restructuring activities. The above adjustment reverses the effect of this one-time gain so 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 so as to not impact the underlying growth rates of the business for this non-organic impact.

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.

Fixed Customer Relationships generally are counted on a unique premises basis. Accordingly, if an individual receives Sunrise’s services in two premises (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 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.
