Neil Berkett, Chief Executive Officer of Virgin Media, said: “In the first quarter of 2012, we’ve made steady progress against our strategy. Demand for superfast broadband and TiVo, the UK’s first mass-market connected TV service, continued to gather momentum. We once again demonstrated the unique power of our network by starting to double the broadband speeds of over four million customers. We have seen an increase in ARPU and greater customer loyalty with our best subscriber retention for two years and this has reinforced our confidence that people increasingly appreciate the value of a genuinely next generation digital experience.

In addition, a growing base of mobile contract subscribers together with strong revenues in Virgin Media Business showed again that we have multiple sources of revenue growth. Over the remainder of 2012, we expect continued steady progress across the company which, combined with the underlying resilience of our business model, will translate into strong cash flow and shareholder returns.”

SUMMARY FINANCIAL RESULTS

SELECTED CONSUMER OPERATIONS STATISTICS

OVERVIEW

Sustained revenue growth from multiple sources

Financial performance in the first quarter was in line with the guidance provided with our full-year results announcement. Revenue exceeded £1.0bn, up 2.4%, while gross margin(5) improved by 3.2% to £589m. SG&A increased 9.1% to £213m, principally due to the phasing of marketing spend. In line with our guidance, this resulted in flat OCF at £376m. Operating income increased 18% to £131m and net income amounted to £7m, up by £4m.

In line with our previous guidance, Free Cash Flow was lower due to the phasing of marketing expense and increased capital expenditure. It was down 13% to £87m. Net cash provided by operating activities was down 22% to £212m.

Continued cable customer and ARPU growth

Consumer cable revenue increased 1.8% to £678m, primarily due to 1.7% cable ARPU growth.

The cable customer base grew by 21,200 during the quarter compared to 20,200 a year ago. Gross disconnections fell year-on-year for the second quarter in a row and to the lowest number since Q1-10. On a percentage basis, monthly churn was flat at 1.2%.

Strong superfast broadband and next-generation TV now as standard

Demand for faster broadband continues to grow as we again saw around half of new subscribers taking superfast speeds of 30Mb or more. We added 146,700 such customers during the quarter, taking the total to nearly 850,000, which is more than triple the number of a year ago. This includes over 250,000 on our 50Mb, 60Mb or 100Mb tiers. We completed the roll-out of 100Mb, the country’s fastest widely available broadband service, across our entire network ahead of schedule at the end of March.

We have also started our programme to double the broadband speeds of over 4m customers. This significant eighteen month initiative has been marketed, primarily to existing customers, through the acclaimed “Double Speeds” advertising campaign featuring Usain Bolt and Sir Richard Branson. As of April 24th, we had doubled the speeds of approximately 250,000 customers, representing around 6% of our cable broadband base.

At the same time, the appeal of TiVo is driving strong pay TV performance. We added 242,000 more TiVo customers during the quarter to reach a total of 677,100 at the quarter-end, which represents 18% of our TV customer base. This already exceeds the proportion of our customers on our lowest free tier, which now stands at 17% having fallen from 21% a year ago, as we successfully increased the number of paying TV customers by 50,600 in the quarter.

Immediately after the quarter-end, we introduced new product “Collections” that include TiVo, HD TV and superfast broadband as standard for new customers. This creates further differentiation between our products and those of our competitors.

Driving mobile revenue through contract cross-sell

Continued improvement in the proportion of customers with mobile contracts resulted in 1.2% total mobile revenue growth to £138.5m. The strong contract revenue growth was partially offset by the headwinds of declining prepay revenue and regulatory changes to mobile termination rates (“MTR”). Contract service revenue increased 14.9% to £99.9m, while prepay service revenue declined by 24.2% to £35.2m. MTR changes reduced the amount of inbound mobile revenue we received by approximately £6m in the quarter. We estimate that mobile revenue would have increased by approximately 6%, excluding this regulatory factor, when compared to the same quarter last year. 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.

4

We increased our contract base by 64,100 in the quarter, up from 52,600 in the first quarter of last year. Virtually all of these contract net additions were into cable homes. The total contract base increased by 26% from a year ago to 1.6m.

Our prepay subscriber base reduced by 93,400 in the quarter compared to a decline of 120,300 in the same quarter last year. This takes the prepay base to 1.4m, down 18% compared to a year ago.

At the quarter-end, we had approximately 764,800 cable households with at least one Virgin Mobile contract, which is up 33% year-on-year. These homes had around 1.1m contract mobiles. We also estimate we have a further 206,000 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 15.0%, compared to around 12.4% a year ago. We have approximately 723,000 quad-play customers, which is up 21% year-on-year.

Growing Business Data

Virgin Media Business (“VMB”) revenue of £170.4m was up 7.1%, which represented 47% of total group revenue growth. We continued to execute on our strategy to drive the division’s growth through higher margin data products and projects such as London Grid for Learning (“LGfL”) and MBNL mobile backhaul.

In March, Virgin Media won the contract to provide public access Wi-Fi at up to 120 Tube stations in London. Partially leveraging existing VMB infrastructure, this new service will launch as a free, unlimited service for all Tube passengers for the London 2012 Games and will continue to offer free Transport for London live travel information via a new online portal after the Games. In doing this, we are putting the power of our fibre optic cable network at the disposal of customers out of the home for the first time.

VMB has been awarded a place on a new Public Services Network (PSN) Connectivity Framework run by the Government Procurement Service allowing public sector organizations to take advantage of the value and services VMB can offer through the new framework.

In addition, global property consultancy Knight Frank is supporting staff productivity with the implementation of a high-speed network from Virgin Media Business. The network, which will be delivered as part of a new five year contract, will provide staff in all Knight Frank’s 60 offices across the UK with increased bandwidth and easy access to its multimedia property database.

VMB also implemented a new telephone system for Portsmouth City Council powered by our fibre optic network.

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 expected share buybacks from mid-2010 to the end of 2012.

During the first quarter of 2012, we repurchased 10.2m shares at a cost of £157m through a $250m accelerated repurchase programme. We have repurchased 62.7m shares since mid-2010. As at March 31, 2012, we had 277.7m shares outstanding.

We have £296m remaining for share buybacks authorized by our Board to the end of 2012, which represents approximately 7% of our equity market capitalization as of April 24, 2012.

Based on the share price as of April 24, 2012, 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.

5

In order to lower future interest expense and lengthen debt maturities, we issued $500m 5.25% senior notes due 2022 in March, which funded the tender and cancellation of $500m of our outstanding 9.50% senior notes due 2016. The total premium cost and fees of the tender, which was funded by cash on hand, was approximately £50m and this forms part of the £225m authority for capital return transactions relating to our debt and convertible debt discussed above.

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 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 MARCH 31, 2012

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

TOTAL REVENUE

Total revenue in the first quarter was up 2.4% to £1.0 billion, due to growth in both the consumer and business segments.

CONSUMER SEGMENT

Cable

Cable revenue in the first quarter was up 1.8% at £678.3m, mainly reflecting growth in cable ARPU.

Mobile

Mobile revenue in the quarter was £138.5m, up 1.2% due to growth in contract service revenue, partially offset by the regulated change in MTRs and the decline in prepay service revenue.

Non-cable

Non-cable revenue in the quarter was down £1.3m at £19.0m mainly due to a reduction in the customer base from 272,700 to 233,000.

BUSINESS SEGMENT

Business revenue in the quarter was £170.4m, up 7.1%.

Retail data revenue was up 22.0% to £79.8m, reflecting our successful strategy of focusing on higher margin data revenue and increasing demand for our data products.  Wholesale data revenue was down 13.6% at £36.3m due mainly to first quarter revenue last year including some non-recurring fees relating to a single contract.

Retail voice revenue was down 3.9% to £37.4m, reflecting the continued structural decline in voice telephony. Wholesale voice revenue was up £3.7m at £7.3m. Local Area Network Solutions and other revenue was relatively flat at £9.6m.

6

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

Operating costs (exclusive of depreciation) were £416.9m in the quarter, up 1.4% as lower consumer cost of sales were partially offset by higher business cost of sales and higher network and other operating costs. Gross margin for the quarter grew from 58.1% to 58.6%.

SG&A increased by 9.1% to £212.8m for the quarter, mainly due to the phasing of marketing costs, which increased by 50% to £52.6m in the quarter. Excluding marketing costs, SG&A was flat at £160.2m.

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

OCF was relatively flat at £376.5m, as the increase in gross margin was offset by higher marketing expense.

OPERATING INCOME

Operating income in the quarter was £130.9m, up 18% mainly due to reduced amortization expense.

Depreciation expense was up 5.0% at £240.2m due mainly to depreciation in respect of new fixed assets, partially offset by certain fixed assets becoming fully depreciated. No amortization expense was incurred in the quarter, compared to £34.1m 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 for the quarter was £7.0m compared to net income of £3.3m in Q1 last year. The improvement was mainly due to increased operating income, increased gain on derivative instruments, reduced amortization expense and reduced interest expense, partially offset by increased loss on extinguishment of debt.

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) in the quarter were up £55.8m to £233.1m mainly due to increased consumer premise equipment spend driven by TiVo, £21.2m spent on the broadband speed upgrade, and a £12.2m increase in Business (commercial) capex which related mainly to installation costs on our MBNL and LGfL contracts.

The total purchase of fixed and intangible assets in the quarter was up £20.8m at £184.1m mainly due to the increase in fixed asset additions (accrual basis) partially offset by the timing of cash payments to suppliers. Total purchase of fixed and intangible assets included £3.1m spent on the broadband speed upgrade. This was lower than the amount spent on an accrual basis as this was the first quarter of the programme and so the timing of cash payments lagged the accrued spend.

Leasing

The total amount of fixed assets acquired under capital leases in the quarter was £23.5m, representing 2.3% of revenue. During the quarter, £21.3m of principal payments on capital leases were made and the capital lease balance at the end of the quarter was £260.2m.

7

The interest charge on capital leases was £4.4m during the quarter.

FREE CASH FLOW

Free Cash Flow for the quarter was down 12.8% to £87.1m mainly due to flat OCF and higher purchase of fixed and intangible assets, partially offset by lower net interest expense. Net cash provided by operating activities was down 21.9% at £212.1m mainly due to increased loss on extinguishment of debt and changes in operating assets and liabilities, partially offset by lower interest payments due to the timing of such payments.

DEBT

As of March 31, 2012, total debt consisted of £750m outstanding under our Senior Credit Facility, £1,692m of Senior Notes, £2,540m of Senior Secured Notes, £538m of Convertible Senior Notes and £261m of capital leases and other indebtedness. Cash and cash equivalents were £141m. Net debt(8) was £5,640m at the quarter-end.

Interest expense in the quarter was £105.6m, down 7.9% due to a lower level of debt and lower average interest rates.
