Neil Berkett, Chief Executive Officer of Virgin Media, said: “In a fast-changing industry and an uncertain

1

economic environment, our 2011 results demonstrate the underlying resilience of Virgin Media’s business model, with modest revenue growth driving robust OCF and record free cash flow. Our next accelerated stock repurchase of $250 million shows our ability and commitment to translate the cash generative characteristics of our business into shareholder value.

Our strategy of focusing on customers who want more from the digital world is paying off. With the number of TiVo customers doubling in the final quarter of the year, our new TiVo service is attracting both new and existing customers. Since its commercial launch mid-way through the year, the number of TiVo subscribers has grown to almost half a million with a large and growing proportion now using its next generation functionality on a regular basis. Demand for better broadband also continues to grow fast, with around half of new customers choosing superfast speeds. The combination of the best TV experience and the best broadband, has enabled us to acquire more new customers in the quarter.

Our confidence in the growing mainstream demand for next generation digital services has recently led us to announce the roll-out of an ambitious programme to double the broadband speeds of over four million customers. This marks a step change in the migration to superfast speeds and, combined with the continued evolution of TiVo, further differentiates the Virgin Media customer experience.

We are also making strong progress in other areas. We are successfully building contract mobile sales into cable homes and Virgin Media Business ended the year strongly as an increasingly important and growing contributor to the group.”

SUMMARY FINANCIAL RESULTS

CONSUMER OPERATIONS STATISTICS

OVERVIEW

Delivering strong Free Cash Flow growth

2011 was a year of modest revenue growth delivering strong Free Cash Flow. Total revenue was up 3.0% to £4.0bn. Rigorous cost control was reflected in an expanded gross margin(5) of 59.8% and SG&A growth of just 0.7%. This resulted in OCF increasing by 5.3% to £1,590m. Operating income increased 67.8% to £540m. Net income amounted to £76m, the first time the company has achieved positive net income for the full year.

Free Cash Flow increased by 20.7% to £498m for the year while net cash provided by operating activities was up 10.7% to £1,149m.

Cable revenue growth

Full year consumer cable revenue increased by 3.0% to £2.7bn, principally as a result of increased ARPU.

Consumer cable revenue growth for the quarter was 0.8%, primarily due to 0.7% ARPU growth, which was less than recent quarters due to a particularly strong comparative quarter. This was a result of several items that affected Q4-10 including heavy snow which caused unusually high telephony usage and a high-profile Pay-Per-View sporting event. Growth in recent quarters had also benefited from strong year-on-year premium revenue growth resulting from the introduction of new HD channels and a repricing and repackaging of premium channels, although these premium revenues are relatively low margin.

The cable customer base grew by 15,000 during the quarter and this was the first quarter since Q2-10 that there has been a year-on-year reduction in gross disconnects.

Leading in superfast connectivity

As the emerging market for faster broadband continues to gather pace, we saw around half of new subscribers in the quarter taking superfast speeds of 30Mb or more. Over the year, we added 579,000 superfast broadband customers with 133,000 added during the quarter. As consumers spend longer online and connect multiple devices, often concurrently with others in the household, they are making use of the greater bandwidth that faster speeds provide. Consequently, in January 2012, we announced an eighteen month programme to double the broadband speeds of over 4m customers, starting from February.

Nearly 1.2m customers currently subscribe to tiers of 20Mb or above, which represents over 28% of our cable broadband base. Nearly 700,000 subscribe to 30Mb or above, including nearly 200,000 customers on our 50Mb or 100Mb tiers, which is up 67% in the year. We are now ahead of schedule for rolling out 100Mb, the country’s fastest widely available broadband service, right across our network. 10m homes are already able to access this superfast speed and the roll out is now due for completion in late spring.

Accelerated TiVo growth

During the year, we made our TiVo services available to new customers for the first time. This next- generation entertainment platform combines live TV with on demand and web. The strong early demand has accelerated with customer numbers doubling in the last quarter. We installed 272,900 more households to reach a total of 435,100 TiVo customers by the end of the year.

We have increased the number of paying TV customers by 56,100 in the quarter and 137,200 over the year. Those on our lowest free “M” tier fell by 55,000 and now represent just 18% of our total TV base, having fallen from 22% a year ago.

Over 72% of our TV base regularly used our on demand TV service during the quarter, averaging 90m views each month. As anticipated, we achieved over 1bn VOD views in 2011, an increase of 14% on 2010.

We currently have around 3.8m TV customers, of which 60% are able to enjoy our growing range of HD channels and on demand programming.

Exploiting mobile growth opportunity

Full year mobile revenue was £552.9m, down 1.3% on 2010, as strong contract revenue growth was offset by prepay revenue decline and regulatory changes to mobile termination rates (“MTR”) that occurred in April 2011. Contract service revenue increased 16.4% to £367.0m in 2011, while prepay service revenue declined by 22.1% to £172.8m. The MTR change reduced the amount of inbound mobile revenue we received by approximately £21m for the full year, when compared to 2010. Mobile revenue would have increased by approximately 2.5%, excluding this regulatory factor, although due to a similar associated reduction in interconnect costs for our mobile and fixed line businesses from these regulatory rates changes, the impact on group OCF was broadly neutral.

Mobile revenue fell by 4.1% or £6.1m in the quarter as an 11.7% growth in contract service revenue to £97.6m was offset by a 19.3% prepay service revenue decline to £41.4m and an approximate £7.4m regulatory MTR impact.

We increased our contract base by a record 102,500 contract customers in the quarter, nearly twice as many as in Q4 last year. Virtually all of these contract net additions were into cable homes — another record at 101,000. The total contract base increased 26% to 1.52m from a year ago. For the first time ever, we now have more contract customers than prepay.

Our prepay subscriber base reduced by 53,500 in the quarter compared to 54,200 in the same quarter last year. This takes the prepay base to 1.51m, down 19% during the year.

At the year-end, we had approximately 728,500 cable households, or 15% of our cable customer base, with at least one Virgin Mobile contract, which is up 33% since the start of the year. These homes had around 1.03m contract mobiles. We also estimate we have a further 211,000 cable households with at least one of our prepay phones, meaning total mobile penetration of the cable base is around 20%, leaving a significant growth opportunity to cross-sell to the remaining 80%.

Quad-play penetration, where a household takes all three cable products and at least one mobile phone service, increased to around 14.5%, compared to around 12.2% at the beginning of the year. We have approximately 697,000 quad-play customers, which is up by approximately 113,000 net customers or 19% during the year.

Growing Business Data

Virgin Media Business finished the year with 13.9% revenue growth in the quarter to deliver full year revenue of £637m, up 6.8% for the year. This full year increase is a result of the strong traction that has been built up throughout the year, with large contract wins such as MBNL now starting to drive revenue. We are continuing to see strong growth in data, with retail and wholesale up 14.6% and 11.2%, respectively, for the full year.

In the fourth quarter, we launched our “Big Red VPN” product to provide unconstrained bandwidth across a customer’s VPN (virtual private network), linking multiple sites to a common, dedicated network ensuring that disparate office locations can operate as though they were on the same premises.

Contract wins in the quarter included the Driver and Vehicle Licensing Agency (DVLA) which has selected Virgin Media Business to provide its business phone lines, supported by an Intelligent Call Management system. In addition, we won a contract with Volkswagen Group UK to deliver a wide area network across 434 dealerships nationwide.

Capital Return Programme update

In July 2011, we announced a second phase capital return programme of up to £850m. In October 2011, we added up to a further £250m to this following the sale of UKTV. The total second phase programme consists of up to £875m of share buybacks and up to £225m in transactions relating to our debt and convertible debt, which may be effected through open market, privately negotiated, and/or derivative transactions until the end of 2012. Combined with our previous capital return programme, this takes the

6

cumulative total to £1.8bn of which £1.25bn is for expected share buybacks from mid-2010 to the end of 2012.

During 2011, we repurchased 40.9m shares at a cost of £635m, of which 13.6m were repurchased in the fourth quarter at a cost of £188m. We have repurchased 52m shares since mid-2010. As at December 31, 2011, we had 286.7m shares outstanding.

Today, we are announcing our plans to immediately initiate the next accelerated stock repurchase to purchase $250m of our common stock. This is a further tranche of our existing authorization, representing approximately 4% of equity market capitalization as of February 6, 2012.

Following this, we will have £295m of remaining share buybacks authorized to the end of 2012, which represents approximately 7% of our equity market capitalization as of February 6, 2012.

Based on the current share price, 25% of our sharecount in mid-2010 is expected to have been repurchased by the end of 2012, assuming the full Board authority is used in 2012.

We remain on track to achieve our long-term net leverage, Net Debt to OCF(4), target of approximately 3.0x between mid-2012 and mid-2013 as previously announced.

The open market, privately negotiated and derivative transactions described above may be implemented by brokers for the company within certain pre-set parameters and purchases may continue during closed periods in accordance with applicable restrictions. The stock so acquired will be held in treasury or cancelled. Also, in connection with certain derivative and accelerated buyback transactions, the associated counterparties may hedge their liabilities through transactions in our common stock.

RESULTS FOR THE THREE MONTHS ENDED DECEMBER 31, 2011

Comparisons of financial and operating statistics are to the fourth quarter of 2010, unless otherwise stated.

TOTAL REVENUE

Total revenue in the fourth quarter was up 2.0% to £1.0 billion, as growth in consumer segment cable revenue and business segment revenue were partially offset by reductions in mobile and non-cable revenue in the consumer segment.

CONSUMER SEGMENT

Cable

Cable revenue in the fourth quarter was up 0.8% at £688.5m, mainly reflecting growth in cable ARPU.

Mobile

Mobile revenue in the quarter was £142.2m, down 4.1% due to the regulated change in MTRs that reduced our inbound mobile revenue by approximately £7m and declines in prepay service revenue, partially offset by growth in our contract base. Contract service revenue increased by 11.7% to £97.6m mainly due to subscriber growth, partially offset by the impact of MTRs. Prepay service revenue fell by 19.3% to £41.4m mainly due to a reduction in subscribers.

Non-cable

Non-cable revenue in the quarter was down 3.9% at £19.9m mainly due to a reduction in the customer base.

BUSINESS SEGMENT

Business revenue in the quarter was £173.1m, up 13.9%, mainly due to growth in retail and wholesale data partially offset by lower voice revenue. Retail data revenue was up 17.8% to £73.5m, reflecting our

7

successful strategy of focusing on higher margin data revenue and increasing demand for our data products. Retail voice revenue was down 1.0% to £39.3m. Wholesale data revenue was up 18.4% at £45.5m which included revenues from our new MBNL mobile backhaul contract. Wholesale voice revenue was up £2.3m at £7.2m. Local Area Network Solutions and other revenue was up £1.1m at £7.6m.

OPERATING COSTS AND SELLING, GENERAL AND ADMINISTRATIVE EXPENSES (SG&A)

Operating costs (exclusive of depreciation) were £402.9m in the quarter, down 1.4% as lower consumer cost of sales and lower network and other operating costs were partially offset by higher business cost of sales. Gross margin(5) for the quarter grew from 59.3% to 60.6%.

SG&A increased by 2.8% to £197.1m for the quarter, mainly due to higher facilities and other costs, partially offset by lower employee and outsourcing costs.  Facilities costs were higher mainly due to costs in the fourth quarter of 2010 benefiting from a one-time reduction in dilapidation expense related to our property estate.

OPERATING INCOME BEFORE DEPRECIATION, AMORTIZATION, GOODWILL AND INTANGIBLE ASSET IMPAIRMENTS AND RESTRUCTURING AND OTHER CHARGES (OCF)

OCF increased 5.0% to £423.7m in the quarter, mainly due to revenue growth and reduced operating costs, partially offset by higher SG&A.

OPERATING INCOME

Operating income in the quarter was £166.3m, up 134% mainly due to improved operating results as described above and reduced depreciation and amortization.

Depreciation expense was down 10.1% at £228.6m primarily as a result of certain fixed assets becoming fully depreciated, partially offset by increases in depreciation in respect of new fixed assets. Amortization expense was £28.1m, down 23.4% mainly due to the cessation of amortization of intangible assets that have become fully amortized. All intangible assets have now been fully amortized and therefore no amortization expense is anticipated in 2012.

NET INCOME

Net income for the quarter was £48.2m compared to net income of £37.1m in Q4 last year. The improvement was mainly due to increased operating income and reduced interest expense, partially offset by the lack of income tax benefit that occurred in Q4-10.

CAPITAL EXPENDITURE

Capital expenditure guidance

Excluding the incremental £110m investment in 2012 on our broadband speed upgrade that we announced in January, Virgin Media’s cash capital expenditure (purchase of fixed and intangible assets) will remain within current guidance of 15 to 17% of revenue for 2012 and for future years. In addition, it is expected that the cost of fixed assets acquired under leases will continue to be no greater than 2 to 3% of revenue per annum, in line with recent years. All other strategic growth opportunities will be met within this guidance.

Leasing

At our third quarter results, we confirmed that the initial phase of TiVo set top boxes was financed using operating leases and we were evaluating the opportunity to accelerate the TiVo roll-out with different financing options. We have concluded this review and have taken the decision to convert all TiVo boxes already acquired under operating leases in 2011 and finance them with capital leases. We have also decided not to use operating leases for our consumer premise equipment in 2012 and for the foreseeable future.

The effect of converting the TiVo leases in the fourth quarter is an increase in fourth quarter fixed asset additions (accrual basis)(6) of £55.5m, of which around £30m relates to set top boxes received prior to the

8

fourth quarter. In addition, as a result of this, there has been an identical increase in capital leases of £55.5m in the quarter. Consequently, there is no change to the total purchase of fixed and intangible assets in the quarter resulting from this transaction.

The total amount of fixed assets acquired under capital leases in 2011 was £91.2m, representing 2.3% of revenue. This includes the £55.5m capital leases for TiVo boxes referenced above.

During 2011, £79.2m of principal payments on capital leases were made and the interest charge on capital leases was £14.3m.

Fixed assets

Fixed asset additions (accrual basis)(6) in the quarter were up £85.7m to £227.0m mainly due to the £55.5m conversion of the TiVo operating leases described above, of which £30m related to set top boxes received prior to the fourth quarter. The remainder of the increase was mainly due to increases in scalable infrastructure spend as we continued to upgrade and improve our network and an increase in commercial (business segment) spend, related to recent contract wins.

The total purchase of fixed and intangible assets in the quarter was up 18.0% at £177.4m mainly due to the increases in scalable infrastructure spend and commercial (business segment) spend explained above.

Fixed asset additions (accrual basis) in the year were up 12.3% to £763.0m mainly due to increased spend on consumer premise equipment, scalable infrastructure as we continued to upgrade and improve our network, and an increase in commercial (business segment) spend, partially offset by reduced spend on support capital.

The total purchase of fixed and intangible assets in the year was up 4.5% at £656.7m mainly due to the increases explained above and changes in liabilities related to fixed asset additions.

The total purchase of fixed and intangible assets was 17.3% and 16.5% as a percentage of revenue for the quarter and year, respectively.

FREE CASH FLOW

Free Cash Flow for the quarter was up 1.1% to £139.6m mainly due to higher OCF and lower net interest expense, partially offset by higher total purchase of fixed and intangible assets. Net cash provided by operating activities was up 11.0% at £294.4m mainly due to higher operating income and lower interest expense.

DEBT

As of December 31, 2011, total debt consisted of £750m outstanding under our Senior Credit Facility, £1,720m of Senior Notes, £2,575m of Senior Secured Notes, £551m of Convertible Senior Notes and £258m of capital leases and other indebtedness. Cash and cash equivalents were £300m. Net debt(7) was £5,555m at the year-end.

Interest expense in the fourth quarter was £105.5m, down 11.1% due to a lower level of debt and lower average interest rates.

Notes

Please see Appendix F for a reconciliation of all non-GAAP financial measures to their nearest GAAP equivalents.

(1) OCF is operating income before depreciation, amortization, goodwill and intangible asset impairments and restructuring and other charges. OCF is a non-GAAP financial measure and the most directly comparable GAAP measure is operating income.

(2) Free Cash Flow, or FCF, is OCF reduced by purchase of fixed and intangible assets, as reported in our statements of cash flows, and net interest expense, as reported in our statements of operations. FCF is a non-GAAP financial measure and the most directly comparable GAAP measure is net cash provided by operating activities.

(3) Pay TV base is our total TV customer base less those on the free “M” tier.

(4) Net Debt to OCF is Net Debt divided by OCF. It can be calculated on a last twelve months or on a quarterly annualized basis. On a last twelve months basis it is Net Debt divided by OCF for the last twelve months. On a quarterly annualized basis, it is Net Debt divided by OCF for the quarter multiplied by four. Net Debt to OCF is a non-GAAP financial measure.

(5)  Gross margin is revenue less operating costs, divided by revenue.

(6) Fixed asset additions (accrual basis) is the purchase of fixed and intangible assets as measured on an accrual basis, excluding asset retirement obligation related assets. Fixed asset additions (accrual basis) is a non-GAAP financial measure and the most directly comparable GAAP measure is purchase of fixed and intangible assets.

(7) Net Debt is long term debt inclusive of current portion, less cash and cash equivalents. Net debt is a non-GAAP financial measure and the most directly comparable GAAP measure is long term debt (net of current portion.)
