Underlying voice and data trends remain robust, although voice ARPU growth in the UK and Germany continues to be restrained by the 2004 termination rate cuts. The initial impact of our initiatives to reduce UK churn is encouraging, with short-term churn metrics improving for both our contract and pre-pay customer bases. At the end of the first quarter we are increasingly confident that all our businesses will again deliver all their growth and margin targets in 2005/06." Key performance indicators (KPI) for the three-month period ending 30 June 2005 (including the impact of adoption of IFRS): Service revenue: - - O2 UK net service revenue grew by 3% year-on-year (including termination cut); - - O2 Germany service revenue grew by 24% year-on-year (at constant currency); - - O2 Ireland service revenue grew by 15% year-on-year (at constant currency). Customer numbers: - - O2 added 646,000 customers, taking the total base to 24.6 million - O2 UK added 232,000 customers; - O2 Germany added 412,000 customers; Average revenue per user (ARPU), including impact of IFRS adoption in O2 UK: - - O2 UK blended ARPU GBP271 (Q4: GBP273; Q1 '04/'05: GBP269) - - O2 Germany blended ARPU EUR356 (Q4: EUR363; Q1 '04/'05: EUR367) - - O2 Ireland blended ARPU EUR571 (Q4: EUR565; Q1 '04/'05: EUR556) Mobile data: - - SMS volume grew by 34% year-on-year, to 4.31 billion - - Data as a proportion of service revenue stable at 26.0% - - 34% of O2 customers used non-SMS data services. International Financial Accounting Standards ("IFRS") O2 plc is required, under EU Regulations, to adopt International Financial Reporting Standards as its primary basis of accounting for the year ending 31 March 2006. IFRS has replaced UK Generally Accepted Accounting Principles ("UK GAAP"), under which O2 has prepared and presented its financial statements up to 31 March 2005. The principal effects on O2's reported financial information arise from the following differences in accounting under IFRS compared with UK GAAP: - - recognition of mobile number portability ("MNP") revenue on a net basis; - - cessation of goodwill amortisation; - - recognition of all employee benefits, principally pension obligations; - - inclusion of a charge for employee share schemes based on fair value; - - recognition of certain financial instruments at fair value; - - recognition of certain deferred tax liabilities; - - de-recognition of dividends not declared at period end. The impact on financial results and key performance indicators ("KPIs") for the year ended 31 March 2005, compared with the UK GAAP reported results, are as follows: - - O2 UK revenue reduced by GBP108 million, to GBP3,922 million; - - O2 UK 12-month rolling blended ARPU reduced by GBP8, to GBP273; - - EBITDA reduced by GBP8 million, to GBP1,760 million; - - O2 UK EBITDA margin increased from 29.4 % to 30.2%; - - Underlying earnings(1) GBP727 million (UK GAAP: GBP735 million); - - Underlying earnings(1) per share 8.4 pence (UK GAAP: 8.5 pence); - - Basic earnings per share of 5.7 pence (UK GAAP: 3.5 pence); - - Group net debt increased by GBP1 million, to GBP79 million; - - Net assets reduced by GBP86 million, to GBP10,195 million. (1) Before goodwill and UMTS licences amortisation and exceptional items O2 UK - Mobile Number Portability (MNP) O2 UK receives income and incurs a related expense on calls which are "ported" to another mobile operator. Porting arises when an O2 customer leaves O2 and joins another network and takes their existing mobile number to their new network. All calls received by that customer are still routed via the O2 network to the network of the new operator. For all incoming calls to the O2 network, O2 receives a termination fee per minute and is required to pass that fee to the new operator. The receiving operator pays O2 a small commission for conveying the call. Under UK GAAP O2 UK recognised the termination fee on a gross basis and thus included these amounts in both revenue and cost of sales. Under IFRS O2 will recognise the termination payments on a net basis. This adjustment is solely a reclassification which does not alter profit or cash flow. However, in the year ended 31 March 2005 the adjustment reduces O2 UK's total revenue and operating costs by GBP108 million each, increases O2 UK's EBITDA margin by 0.8 percentage points to 30.2%, and reduces 12-month rolling blended ARPU by GBP8. A summary of the quarterly and half-yearly changes for O2 UK for the year ended 31 March 2005 is presented in Appendices 1 and 2. A full description of the differences between UK GAAP and IFRS, and the impact on O2 plc's primary financial information for the 12 months ended 31 March 2005 and 6 months ended 30 September 2004, is presented in detail in O2 plc Release ref. PR0518. FIRST QUARTER Operating review O2 UK (including the impact of adoption of IFRS) First quarter net service revenue grew by 3% year-on-year. The impact of the 30% termination rate cut in September 2004, and the loss of the BT contract during the second half of last year, reduced net service revenue by approximately 8% compared to the first quarter of 2004/05. The business demonstrated continuing underlying momentum. A total of 232,000 net new customers were added in the quarter, taking the base to 14.616 million, 8.1% higher than at the same time last year. Blended ARPU was GBP271, GBP2 lower than at the end of the previous quarter but GBP2 higher than in the first quarter last year, despite the approximately GBP15 impact of the September 2004 termination rate. The initiatives introduced to reduce churn are demonstrating encouraging progress in both the pre-pay and contract markets. The level of contract upgrades is running well ahead of the same time last year, and the initial response rate to the pre-pay Reward offer is ahead of expectations. The churn metrics are starting to improve, with the monthly churn rate declining for both the contract and pre-pay customer bases. O2 Germany Service revenue grew by 24% at constant currency in the first quarter, driven by the continuing high level of net customer additions. A total of 412,000 net new customers were added in the quarter, taking the base to 8.388 million, 33% higher than at the same time last year. The 17% termination rate cut in December 2004 reduced service revenue by approximately 3% compared to the first quarter of 2004/05. Blended ARPU remained the highest in the German market, at EUR356, down from EUR363 in the previous quarter, partly reflecting the impact of the termination rate cut. The changing customer mix also affected blended ARPU, due to the recent strong growth of the pre-pay customer base. Contract ARPU of EUR527 was EUR4 lower than the previous quarter, reflecting the recent rapid growth of new O2 Active customer propositions, in addition to the ongoing success of the high-ARPU Genion Homezone range of services. A total of 268,000 net new pre-pay customers were added in the quarter, well ahead of the growth achieved in the same quarter last year. Pre-pay ARPU remained broadly flat at EUR139, in spite of the December 2004 termination rate cut. The Tchibo Mobile joint venture continued to perform well, with 83,000 net new customers added in the quarter. O2 Ireland Service revenue in the first quarter grew by 14.6% at constant currency, driven by both customer growth and improving ARPU. The customer base remained broadly flat quarter-on-quarter, but was 9.7% higher than at the same time last year. Twelve-month rolling blended ARPU of EUR571 was 2.7% higher than in the first quarter of 2004/05, reflecting strong underlying voice and data usage trends. O2 Airwave In July Airwave was awarded the contract to provide a communications service to all Ambulance Trusts in England. The total value of the contract for network access and provision and integration of equipment is approximately GBP390 million over 13 years. Airwave will invest approximately GBP75 million over a three-year period, of which around 50% will cover non-network expenditure. The Scottish and Welsh Ambulance Service Trusts are scheduled to decide on their choice of communications solutions in the near future. O2 Airwave is also short-listed for the Fire Service national communications contract, and 78 other public safety organisations are already signed up to the service. OUTLOOK At the end of the first quarter, the Group is increasingly confident that all its operating businesses will deliver all of their revenue, margin and capital expenditure targets for the year ending 31 March 2006: - - O2 UK The Group expects mid-single digit growth in net service revenue, reflecting the remaining five months' impact of the September 2004 termination rate cut, and continuing competition in what is now a highly penetrated mobile market. The EBITDA margin is expected to remain broadly stable, reflecting the competitiveness of the market, and O2 UK's programme to allocate substantial resources to develop additional customer-facing capabilities, and achieve higher long-term customer retention. (Note that the change in the definition of service revenue under IFRS does not have a material impact on either the service revenue growth or EBITDA margin guidance.) - - O2 Germany The Group expects to deliver further strong service revenue growth, mainly driven by continued rapid growth of the customer base. The EBITDA margin is expected to improve further, to around 20%, reflecting O2 Germany's continuing prioritisation of revenue growth, as well as the impact of UMTS network running costs and the continued costs of national roaming. - - Group capital expenditure Capital expenditure is expected to be broadly in line with the total incurred in 2004/05 (excluding the network sharing agreement payments in Germany), with higher UMTS network investment, particularly in Germany, offsetting the reduction in Airwave capital expenditure due to completion of the police network roll-out.
