SUMMARY FINANCIAL RESULTS

SELECTED CONSUMER OPERATIONS STATISTICS

3

OVERVIEW

Sustainable revenue growth

Total revenue increased 2.8% in the quarter to £1,028m due to growth in both consumer and business segments. Gross margin(4) improved by 4.4% to £624m. SG&A remained relatively flat at £202m, resulting in OCF of £423m, up 6.1%. Operating income increased 40% to £180m and net income was £124m, compared to a net loss of £74m in the third quarter last year.

Free Cash Flow was down 11% to £120m reflecting the incremental capital investment in our broadband speed upgrade programme. Net cash provided by operating activities was up 23% to £365m.

Continued cable revenue growth

Consumer cable revenue increased 2.9% to £704.7m, reflecting 1.8% cable ARPU growth and an increase of 1.3% in the size of our customer base.

The number of cable customers we serve grew by 39,500 during the quarter compared to 6,300 in Q3-11. Churn fell from 1.7% to 1.4% with gross disconnections down year-on-year for the fourth quarter in a row. These fell by 14% to 203,500.

We added a net 30,200 triple-play customers during the quarter with triple-play penetration increasing to 64.7%.

Strong superfast broadband and TiVo demand

Total broadband net additions in the quarter were 56,900 which is more than double as many as a year ago. We continued to add customers taking superfast speeds (30Mb and above) through new customers joining as well as upgrading existing customers. This superfast customer base increased by 452,900 during the quarter, taking the total to 1.8m or 42% of our broadband base.

Demand for even faster speeds remains strong with around 44% of new broadband subscribers taking speeds of 60Mb or higher during the quarter. We now have 837,500 customers on tiers between 50Mb and 120Mb.

Our programme to double the broadband speeds of over 4m customers continues with over 40% of our network upgraded for the new faster speeds as of October 22, 2012.

At the same time, the appeal of our TiVo service is driving pay TV growth. We added 205,900 more TiVo customers during the quarter to reach a total of 1.14m at the quarter-end, which represents 30% of our TV customer base. This uptake has helped to drive the overall number of paying TV customers, which increased by 52,200 in the quarter.

While TiVo demand remained strong, we managed the mix between new and existing customers to optimise returns resulting in lower net additions than in the previous quarter. However, we achieved our highest ever TiVo gross additions from new customers in the third quarter, whilst migrations and cross-sell only accounted for around 48% of TiVo gross additions. This compares to around 60% of TiVo gross additions coming from migrations and cross-sell in the previous four quarters.

In the coming weeks, we will be launching the latest enhancement to our Virgin Media TiVo service - Virgin TV Anywhere.  This new development will allow our TV customers to stream live channels to their iPhone or iPad, with even more available on their PC, Mac or laptop, including thousands of hours of on demand content. The iPad and online versions will also allow Virgin Media TiVo customers to tap into their TiVo boxes to record shows, manage their recordings and change their series links.

We also re-launched our on demand movie pay-per-view service as ‘Virgin Movies’.  The revitalised movie service offers over 500 of the latest films straight from the cinema as well as a massive catalogue of films available on-demand on TV or via the web with the online service available to everyone, including non-Virgin Media customers as well.

Mobile — sustained contract revenue growth

Mobile revenue was £136.8m, down 3.1% largely due to regulatory changes to mobile termination rates (“MTR”) which reduced the amount of inbound mobile revenue we received by approximately £7m in the quarter compared to Q3-11. Due to a similar associated reduction in interconnect costs for our mobile and fixed line businesses from these regulatory

4

rates changes, the impact on group OCF was broadly neutral. A decline in prepay service revenue of 22% to £34.5m was partially offset by the 5.5% growth in contract service revenue to £99.2m.

We increased our contract mobile base by 28,900 in the quarter. Contract net additions slowed as we shifted focus in the quarter more towards quality customer growth with the launch of new all inclusive tariffs. We also focused handset investment more towards customer retention and particularly those customers coming out of contract at the end of their initial two-year term. We are planning a similar approach in the fourth quarter.

The total contract base increased 18% from a year ago to 1.7m, while our prepay subscriber base reduced by 24,100 compared to a decline of 138,300 in the comparable period last year.

At the quarter-end, we had approximately 809,800 cable households with at least one Virgin Mobile contract, which is up 22% year-on-year. These homes had around 1.2m contract mobiles. We also estimate we have a further 205,400 cable households with at least one of our prepay phones, meaning total mobile penetration of the cable base is around 21%, leaving a significant growth opportunity to cross-sell to the remaining 79%.

Quad-play penetration, where a household takes all three cable products and at least one mobile phone service, increased to around 15.6% of our residential cable customer base, compared to around 13.7% a year ago. We have approximately 757,000 quad-play customers, which is up 15% year-on-year.

Growing Business data

Virgin Media Business revenue of £168.6m was up 9.5% in the quarter. Revenue for the nine months was £505.0m, up 8.8%, which represented 44% of total group revenue growth for the nine months.

Continuing our strength in the Public Sector, we have recently been selected as supplier by the Yorkshire & Humberside Partnership Management Board.

As a result of our focus on mobile backhaul we have started to benefit from incremental revenue this quarter from an extension to our current MBNL deal for an additional aggregation network and an extra 150 sites on top of the 2,000 sites under the existing contract.

Capital Return Programme update

In July 2011, we announced a second phase capital return programme of up to £850m, which was increased in October 2011 by up to a further £250m 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 cumulative total to £1.8bn, of which £1.25bn is for completed or expected share buybacks from mid-2010 to the end of 2012.

In July, we entered into a $175m capped accelerated stock repurchase programme (“ASR”) for a sterling cost of £113m, under which we have received approximately 5.9m shares thus far. The final number of shares that we will ultimately repurchase under this ASR will be determined on or before October 25, 2012.

We have £122m remaining for share buybacks authorised by our Board to the end of 2012, which represents approximately 2.5% of our equity market capitalisation as of October 21, 2012. As at September 30, 2012, we had 268.4m shares outstanding.

Approximately 24% of our share count at June 30, 2010 is expected to have been repurchased(5) by the end of 2012, assuming the full Board authority is used in 2012, based on the share price as of October 21, 2012.

On October 10, we announced the commencement of tender offers by our subsidiary Virgin Media Finance PLC (the “Issuer”) to purchase any and all of its dollar- and euro-denominated 9.50% Senior Notes due 2016 and up to $500 million aggregate principal amount of its dollar-denominated 8.375% Senior Notes due 2019 and its sterling-denominated 8.875% Senior Notes due 2019.

The total premium cost and fees of the tender are expected to be approximately £130m, which forms part of our £225 million second-phase Capital Return Programme, announced in July 2011, of which £175 million remains available to optimise Virgin Media’s outstanding debt structure. The purpose of the tender offers is to enable Virgin Media to lower its

5

interest cost and enhance its capital structure by further extending its amortisation schedule. Virgin Media’s ongoing share buyback programme is still in place and is unaffected.

The terms and conditions of the tender offers are described in the Offer to Purchase dated October 10, 2012 distributed to holders of the Notes. The tender offers are subject to the satisfaction of a financing condition requiring the completion by Virgin Media Inc. or one of its subsidiaries of an offering of debt securities, a loan or other financing transaction, on terms satisfactory to Virgin Media, to raise sufficient funds for the Issuer to pay the total consideration for the Notes. Neither the tender offer for the 2016 Notes nor the tender offer for the 2019 Notes is conditioned upon successful completion of the other offer.

We remain on track to achieve our long-term net leverage, Net Debt to OCF(6), target of approximately 3.0x by mid-2013, as previously announced.

The 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 SEPTEMBER 30, 2012

Comparisons of financial and operating statistics are to the third quarter of 2011, unless otherwise stated.

TOTAL REVENUE

Total revenue was up 2.8% to £1,028m, due to growth in both the consumer and business segments.

CONSUMER SEGMENT

Cable

Cable revenue was up 2.9% at £704.7m, reflecting growth in both cable ARPU and the customer base.

Mobile

Mobile revenue was £136.8m, down 3.1% largely due to the regulated change in MTRs and the decline in prepay service revenue, partially offset by growth in contract service revenue.

Non-cable

Non-cable revenue was down £2.2m to £17.6m mainly due to a reduction in the customer base from 261,300 to 203,900.

BUSINESS SEGMENT

Business revenue was £168.6m, up 9.5%.

Retail data revenue was up 12.6% to £78.0m, following our strategy of focusing on increasing demand for data products.  Wholesale data revenue was up 36% at £45.5m due mainly to revenue from new contracts.

Retail voice revenue was down 13.3% to £32.7m, reflecting the continued structural decline in voice telephony. Wholesale voice revenue was up £1.0m to £5.0m. Local Area Network Solutions and other revenue was down £2.1m to £7.4m.

The nature of this segment is that significant contracts will cause some unevenness in our revenues as we continue to grow. For example, revenue growth in this quarter was helped by replacing and enhancing a contract with a key customer.

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

Operating costs (exclusive of depreciation) were £403.3m, up 0.4% as lower consumer cost of sales were partially offset by higher business cost of sales and higher network and other operating costs. Gross margin percentage grew from 59.8% to 60.8%.

SG&A was relatively flat, increasing by just 0.9% to £201.7m.

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

OCF was up 6.1% at £422.7m, mainly due to improved revenue and gross margin.

OPERATING INCOME

Operating income was £180.0m, up 40%, mainly due to improved revenue and gross margin and reduced amortization expense.

Depreciation expense was up 3.3% at £243.5m. The increase in depreciation expense was primarily a result of depreciation in respect of fixed asset additions with a generally shorter useful economic life than existing assets, combined with the acceleration of depreciation on certain assets that will no longer be required as a result of our re-tiering program, partially offset by fixed assets becoming fully depreciated.

No amortization expense was incurred, compared to £28.1m in the same quarter last year, as all intangible assets subject to amortization became fully amortized in the fourth quarter of 2011.

NET INCOME

Net income was £123.9m compared to a net loss of £73.8m in the third quarter last year. The improvement was mainly due to a third quarter gain of £44.0m on derivative instruments this year compared to a £59.3m loss in the third quarter last year. This gain was principally due to an increase in the value of our conversion hedges, which was driven by an increase in our share price during the quarter.

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.

Fixed assets

Fixed asset additions (accrual basis)(7) were up £19.8m to £203.2m mainly due to £23.3m spent on the broadband speed upgrade.

The total purchase of fixed and intangible assets was up £47.0m at £202.7m mainly due to the increase in fixed asset additions (accrual basis) and the timing of cash payments to suppliers, partially offset by increases in assets acquired under capital leases. Total purchase of fixed and intangible assets included £31.1m spent on the broadband speed upgrade.

Leasing

The total amount of fixed assets acquired under capital leases was £24.7m, representing 2.4% of revenue in the quarter. We made principal payments on capital leases of £21.5m and the capital lease balance increased from £241.0m at the end of the second quarter to £244.2m at the end of the third quarter.

7

The interest charge on capital leases was £3.6m during the quarter.

FREE CASH FLOW

Free Cash Flow was down 11% to £120.0m mainly due to higher purchase of fixed and intangible assets, partially offset by increased OCF and lower net interest expense. Net cash provided by operating activities was up 23% at £364.5m mainly due to increased operating income, a reduction in cash interest driven by the timing of payments on our debt, and a favourable change in operating assets and liabilities.

DEBT

As of September 30, 2012, total debt consisted of £750m outstanding under our Senior Credit Facility, £1,676m of Senior Notes, £2,582m of Senior Secured Notes, £541m of Convertible Senior Notes and £244m of capital leases and other indebtedness. Cash and cash equivalents were £113m. Net debt(8) was £5,679m at the quarter-end.

Interest expense was £100.2m, down 6.9% mainly 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) Paying TV base is our total TV customer base less those on packages which include a free TV service provided with a non-TiVo set top box.

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

(5) Based on closing share price as of October 21, 2012 and 268.4m shares outstanding at September 30, 2012.

(6) 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 and Net Debt to OCF are non-GAAP financial measures.

9

(7) 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.

(8) 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.)
