Unless otherwise determined by Liberty Global or required by the Takeover Code, and permitted by applicable law and regulation, the Acquisition will not be made, directly or indirectly, in, into or from a Restricted Jurisdiction where to do so would violate the laws of that jurisdiction and no person may vote in favor of the Acquisition by any use, means, instrumentality or form within a Restricted Jurisdiction or any other jurisdiction if to do so would constitute a violation of the laws of that jurisdiction.

Further information in relation to this profit forecast is provided in Section B.9 of this Summary, below. B.7 Selected historical key financial information The following tables present selected historical financial information of Liberty Global and its consolidated subsidiaries. The following selected financial data was derived from our consolidated financial statements as of and for the year ended December 31, 2015 and the unaudited financial results for the three months ended March 31, 2016. This information is only a summary and should be read together with Part IV (Operating and Financial Review of Liberty Global) Review of Operations and our 2015 Consolidated Financial Statements and 2014 Consolidated Financial Statements attached as Annex I to the Original Prospectus, and paragraph 2.3 (Operating and financial review of Liberty Global) and Annex I (Condensed Consolidated Financial Statements) of this Second Supplementary Prospectus. 1

B.9 Profit forecast or estimate In the May Release, Liberty Global confirmed the following full-year 2016 financial guidance targets, which were deemed ordinary-course profit forecasts for purposes of the Code: 5% to 7% rebased OCF growth, for Liberty Global Group, excluding the Netherlands and BASE; and 5% to 7% rebased OCF growth for LiLAC Group, excluding CWC. While Liberty Global s OCF measure should not be considered a measurement of profit, the above statements for the year ending December 31, 2016, are deemed to be profit forecasts for the purposes of the Prospectus Rules (the Liberty Global Profit Forecast ). The Liberty Global Profit Forecast has been prepared on a basis consistent with the accounting policies for Liberty Global, which are in accordance with U.S. GAAP and the basis used to prepare the 2015 Consolidated Financial Statements and the 2014 Consolidated Financial Statements, as well as those which Liberty Global anticipates will also be the basis applicable for the year ending December 31, 2016. Liberty Global has prepared the Liberty Global Profit Forecast based on audited financial results for the year ended December 31, 2015, unaudited financial results for the three months ended March 31, 2016 and an internal management forecast to December 31, 2016. 2

The principal assumptions upon which the profit forecast is based are included below. Our 2016 guidance for the Liberty Global Group mentioned above excludes our Dutch business, Ziggo, and the recently acquired BASE in Belgium, whereas the 2016 guidance for the LiLAC Group excludes CWC. There is a clear distinction made between assumptions which the Liberty Global Directors (or other members of Liberty Global s management) can influence and those which they cannot influence. Factors outside the influence or control of the Liberty Global Directors (and other members of Liberty Global s management): economic and business conditions and industry trends in the countries in which we operate; the competitive environment in the industries in the countries in which we operate, including competitor responses to our products and services; fluctuations in currency exchange rates and interest rates; instability in global financial markets, including sovereign debt issues and related fiscal reforms; consumer disposable income and spending levels, including the availability and amount of individual consumer debt; changes in consumer television viewing preferences and habits; consumer acceptance of our existing service offerings, including our digital video, broadband internet, fixed-line telephony, mobile and business service offerings, and of new technology, programming alternatives and other products and services that we may offer in the future; changes in laws or treaties relating to taxation, or the interpretation thereof, in the U.K., U.S. or in other countries in which we operate; changes in laws and government regulations that may impact the availability and cost of capital and the derivative instruments that hedge certain of our financial risks; the ability of suppliers and vendors (including our thirdparty wireless network providers under our MVNO arrangements) to timely deliver quality products, equipment, software, services and access; and events that are outside of our control, such as political unrest in international markets, terrorist attacks, malicious human acts, natural disasters, pandemics and other similar events. Factors within the influence or control of the Liberty Global Directors (or other members of Liberty Global s management): our ability to maintain or increase the number of subscriptions to our digital video, broadband internet, fixed-line telephony and mobile service offerings and our average revenue per household; 3

our ability to maintain or increase rates to our subscribers or to pass through increased costs to our subscribers; there will be no material change in the present management or control of Liberty Global or its existing operational strategy; and that Liberty Global s accounting policies will be consistently applied in the financial year to December 31, 2016. The Liberty Global Directors have considered the Liberty Global Profit Forecast and confirm that it is valid as at the date of this this Second Supplementary Prospectus and has been properly compiled on the basis of the assumptions set out above and that the basis of the accounting used is consistent with Liberty Global s accounting policies, including those used in the preparation of the 2015 Consolidated Financial Statements and the 2014 Consolidated Financial Statements. 4

Excluding the effect of acquisitions (RGUs added on the acquisition date), but including post-acquisition date changes in RGUs, we added 155,900 RGUs on an organic basis during the three months ended March 31, 2016 as compared to 71,100 RGUs added on an organic basis during the corresponding prior-year period. The organic RGU growth during the three months ended March 31, 2016 is primarily attributable to the net effect of (i) an increase of 178,200 broadband internet RGUs, (ii) a decrease of 161,000 basic video RGUs, (iii) an increase of 116,000 fixed-line telephony RGUs and (iv) an increase of 26,400 enhanced video RGUs. In addition, excluding the effect of acquisitions, we added 32,300 mobile subscribers during the three months ended March 31, 2016, including an increase in postpaid mobile subscribers of 99,800 and a decrease in prepaid mobile subscribers of 67,500. We are experiencing significant competition from incumbent telecommunications operators (particularly in the Netherlands and, to a lesser extent, Switzerland, where the incumbent telecommunications operators are overbuilding our networks with FTTx and advanced digital subscriber line technologies), DTH operators and/or other providers in all of our broadband communications markets. In certain of our markets, this significant competition, together with the maturation of these markets, has contributed to organic declines in revenue, RGUs and/or average monthly subscription revenue per average cable RGU or mobile subscriber, as applicable, (ARPU), the more notable of which include: (i) (ii) organic declines in cable subscription and overall revenue in the Netherlands during the first quarter of 2016, as compared to the first quarter of 2015; organic declines during the first quarter of 2016 in (a) video RGUs in the majority of our markets, as declines in our basic video RGUs generally exceeded additions to our enhanced video RGUs (including migrations from basic video) in these markets, (b) fixed-line telephony RGUs in Chile and the Netherlands and (c) total RGUs in the Netherlands and Switzerland/Austria; and (iii) organic declines in overall cable ARPU in the Netherlands and many of our other markets during the first quarter of 2016, as compared to the first quarter of 2015. Concerns also exist with respect to the Puerto Rico government s cash flows and, accordingly, its ability to meet its debt obligations. On May 1, 2016, Puerto Rico s government failed to pay 367.0 million of the 422.8 million of debt obligations that were due as of such date, and on July 1, 2016, another 1.9 billion will become due. During 2015, the Puerto Rico government enacted a new tax law that, among other things, (i) increased the sales and use tax rate from 7.0% to 11.5%, effective July 1, 2015, and (ii) provided for the taxing of services between businesses at a rate of 4.0%, effective October 1, 2015. Prior to the new tax law, such services were exempt from taxation. Effective June 1, 2016, the aforementioned sales and use tax will be replaced with a VAT of 10.5% and a sales and use tax of 1.0%. The 10.5% VAT will also apply to services between business, which represents a significant increase in the tax rate. More changes to the Puerto Rico tax system are expected during 2016. Currently, there is legislation under analysis in Puerto Rico to postpone or eliminate the application of the new tax regime, including the VAT and the taxation of 9

business-to-business transactions. Puerto Rico s government is also implementing austerity and a number of other measures to improve its solvency. It remains possible, if not likely, that Puerto Rico will be required to restructure its debt obligations. If the fiscal and economic conditions in Puerto Rico were to worsen as a result of these or other factors, (a) the population of Puerto Rico could continue to decline, reducing the future demand for Liberty Puerto Rico s services, and (b) the demand and ability of customers to pay for Liberty Puerto Rico s services could be impaired, which could have a negative impact on Liberty Puerto Rico s results of operations, cash flows and financial condition. Material changes in Liberty Global s results of operations As noted under Overview above, the comparability of our operating results during 2016 and 2015 is affected by acquisitions. In the following discussion, we quantify the estimated impact of acquisitions on our operating results. The acquisition impact represents our estimate of the difference between the operating results of the periods under comparison that is attributable to an acquisition. In general, we base our estimate of the acquisition impact on an acquired entity s operating results during the first three months following the acquisition date such that changes from those operating results in subsequent periods are considered to be organic changes. Accordingly, in the following discussion, variances attributed to an acquired entity during the first 12 months following the acquisition date represent differences between the estimated acquisition impact and the actual results. Our organic growth percentages may be impacted by the fact that the numerator for the organic growth percentages includes the organic growth of the acquired entity, while the denominator may not include any amounts related to the acquired entity. Changes in foreign currency exchange rates have a significant impact on our reported operating results as all of our operating segments, except for Puerto Rico, have functional currencies other than the U.S. dollar. Our primary exposure to foreign currency translation effects (FX) risk during the three months ended March 31, 2016 was to the euro and British pound sterling as 46.5% and 34.4% of our U.S. dollar revenue during the period was derived from subsidiaries whose functional currencies are the euro and British pound sterling, respectively. In addition, our reported operating results are impacted by changes in the exchange rates for the Swiss franc and other local currencies in Europe, as well as the Chilean peso. The portions of the changes in the various components of our results of operations that are attributable to changes in FX are highlighted under Discussion and Analysis of Liberty Global s Reportable Segments and Discussion and Analysis of Liberty Global s Consolidated Operating Results below. For information concerning applicable foreign currency exchange rates in effect for the periods covered by the Interim Results, see Quantitative and Qualitative Disclosures about Market Risk Foreign Currency Exchange Rates below. The amounts presented and discussed below represent 100% of each operating segment s revenue and Adjusted OIBDA. As we have the ability to control Telenet and Liberty Puerto Rico, we consolidate 100% of the revenue and expenses of these entities in our condensed consolidated statements of operations despite the fact that third parties own significant interests in these entities. The noncontrolling owners interests in the operating results of Telenet, Liberty Puerto Rico and other less significant majority-owned subsidiaries are reflected in net earnings or loss attributable to noncontrolling interests in our condensed consolidated statements of operations. Discussion and Analysis of Liberty Global s Reportable Segments General All of the reportable segments set forth below derive their revenue primarily from broadband communications services, including video, broadband internet and fixed-line telephony services. Most of our reportable segments also provide B2B and mobile services. For detailed information regarding the composition of our reportable segments, including information regarding a change we made to our reportable segments during the second quarter of 2015, see note 14 to our condensed consolidated financial statements. The tables presented below in this section provide a separate analysis of each of the line items that comprise Adjusted OIBDA, as further discussed in note 14 to our condensed consolidated financial statements, as well as an analysis of Adjusted OIBDA by reportable segment for the three months ended March 31, 2016 and 2015. These tables present (i) the amounts reported by each of our reportable segments for the current and comparative periods, (ii) the U.S. dollar change and percentage change from period to period and (iii) the organic percentage change from period to period (percentage change after removing FX and the estimated impacts of acquisitions and dispositions). The comparisons that exclude FX assume that exchange rates remained constant at the prior-year rate during the comparative periods that are included in each table. We also provide a table showing the Adjusted OIBDA margins of our reportable segments for the three months ended March 31, 2016 and 2015 at the end of this section. 10

The revenue of our reportable segments includes revenue earned from (i) subscribers to our broadband communications and mobile services and (ii) B2B services, interconnect fees, mobile handset sales, channel carriage fees, installation fees, late fees and advertising revenue. Consistent with the presentation of our revenue categories in note 14 to our condensed consolidated financial statements, we use the term subscription revenue in the following discussion to refer to amounts received from subscribers for ongoing services, excluding installation fees and late fees. In the following tables, mobile subscription revenue excludes the related interconnect revenue. In the U.K. and Belgium, we now offer our customers the option to purchase a mobile handset pursuant to a contract that is independent of a mobile airtime services contract (a Split-contract Program). Revenue associated with handsets sold under a Split-contract Program is recognized upfront and included in other non-subscription revenue. We generally recognize the full sales price for the mobile handset upon delivery, regardless of whether the sales price is received upfront or in installments. Prior to the Split-contract Programs, all revenue from handset sales that was contingent upon delivering future airtime services was recognized over the life of the customer contract as part of the monthly fee and included in subscription revenue. Most of our revenue is derived from jurisdictions that administer VAT or similar revenue-based taxes. Any increases in these taxes could have an adverse impact on our ability to maintain or increase our revenue to the extent that we are unable to pass such tax increases on to our customers. In the case of revenue-based taxes for which we are the ultimate taxpayer, we will also experience increases in our operating expenses and corresponding declines in our Adjusted OIBDA and Adjusted OIBDA margins to the extent of any such tax increases. We pay interconnection fees to other telephony providers when calls or text messages from our subscribers terminate on another network, and we receive similar fees from such providers when calls or text messages from their customers terminate on our networks or networks that we access through MVNO or other arrangements. The amounts we charge and incur with respect to fixed-line telephony and mobile interconnection fees are subject to regulatory oversight in many of our markets. To the extent that regulatory authorities introduce fixed-line or mobile termination rate changes, we would experience prospective changes and, in very limited cases, we could experience retroactive changes in our interconnect revenue and/or costs. The ultimate impact of any such changes in termination rates on our Adjusted OIBDA would be dependent on the call or text messaging patterns that are subject to the changed termination rates.
