Vittorio Colao, Chief Executive, commented:

“We have made a good start to the year in our areas of strategic focus: growth in emerging markets has accelerated, we now have over 5 million customers benefiting from Vodafone Red, and 4G is live in ten markets. In addition, the proposed acquisition of Kabel Deutschland will create an excellent platform for our unified communications strategy in our most important market. Although regulation, competitive pressures and weak economies, particularly in Southern Europe, continue to restrict revenue growth, we continue to lay strong foundations for the longer term.”

OPERATING REVIEW

Group overview

Group revenue including joint ventures1 was £11.1 billion and Group service revenue including joint ventures1 was £10.2 billion. On an organic basis Group service revenue including joint ventures1 decreased by 3.5%*, and by 1.3%* excluding joint ventures. Excluding the impact of mobile termination rate (‘MTR’) cuts Group service revenue, including joint ventures1, fell by 0.7%*.

We continue to see strong growth from our emerging market operations2; however conditions in Europe remain challenging due to ongoing economic and regulatory pressures and increased competitive intensity within some markets during the quarter. Our US associate, VZW, continued to perform strongly.

Northern and Central Europe service revenue decreased by 3.0%*. In Germany service revenue declined by 5.1%*, compared to a 3.5%* decline in the prior quarter, reflecting increased competitive intensity and lower market growth in both the consumer and enterprise segments. Service revenue in the UK fell by 4.5%*, mainly due to price pressure. Compared to the previous quarter this represents a 2.1* percentage point improvement. In Turkey service revenue grew by 15.5%*, compared to 14.5%* in the previous quarter, driven by an easing of competitive pressures and continued strong growth in data and enterprise. In the Netherlands the service revenue decline was broadly unchanged from the previous quarter at 3.7%*.

Southern Europe service revenue including Italy1 fell by 14.4%*. In Italy, market conditions remain difficult, with a significant increase in competitor activity leading to substantial price reductions, a deteriorating economic environment and the ongoing impact of steep MTR cuts. Against this background service revenue declined by 17.6%*, compared to a fall of 17.0%* in the prior quarter. In Spain service revenue fell by 10.6%* due to the lower customer base, particularly in the prepaid segment, and the increased popularity of discounted converged consumer offers in the market. In Italy, Spain and Portugal, fixed broadband customer acquisition continues to gain traction due to the combination of Vodafone Red with fixed broadband tariffs.

Against a background of significant revenue pressures in Europe we continue to drive cost efficiencies through a range of  initiatives including further network sharing agreements (most recently with Wind in Greece), offshoring of business functions to shared service centres, centralisation of procurement costs, and ongoing reductions in support function costs.

AMAP service revenue including joint ventures1 increased by 5.9%*, a 3.1* percentage point improvement on the previous quarter. In India service revenue was up 13.8%* driven by a more stable pricing environment, an improved process of customer verification and continued strong data revenue growth. Service revenue growth at Vodacom improved to 3.2%* (prior quarter -0.7%*). In South Africa service revenue decreased by 0.1%* with the continued growth in data usage and the strong demand for prepaid bundles being more than offset by the impact of an MTR cut and competitive pricing pressures, particularly in the prepaid segment. Our joint venture in Australia experienced an 8.8%* fall in service revenue as the business continues to suffer from weakness in brand perception, although network performance has improved significantly in recent months. In Egypt, service revenue grew strongly at 8.2%*, significantly better than the prior period growth of 3.6%*, due to significant growth in the customer base, higher incoming revenue and continued take-up of data services and social media in particular.

Our push on integrated plans has driven mobile in-bundle customer revenue growth of 9.5%*, including joint ventures1, which now represents 46% of Group mobile service revenue (56% in Europe4). Mobile out-of-bundle customer revenue, including joint ventures1, declined 11.2%* reflecting increased take up of integrated offers and the ongoing economic and competitive pressures in European markets. Group data usage grew by 60%, including joint ventures1, driven by the increasing take-up of smartphones, with 37% of our European customers4 now using smartphones, up from 29% a year ago. In emerging markets3, smartphone penetration continues to increase and now stands at 9.2% in India and 25.4% in Turkey.

We continue to progress our Vodafone 2015 strategy in the areas of Vodafone Red, unified communications and the deployment of 4G services. We now have 5.2 million Vodafone Red customers, since launch in September 2012, representing around 14% of consumer contract customers in our four main markets. Including Vodafone Red, our integrated voice, SMS and data plans now represent 67% of consumer contract revenue in Europe. We have enhanced our unified communications capability in Spain through the commercial launch of high speed VDSL broadband and an agreement with other operators in Spain to share vertical fibre optic infrastructure to support our deployment of a new fibre to the home network. We also announced our intention to acquire Kabel Deutschland, the biggest cable operator in Germany, in order to create a leading unified communications provider, which complements the wholesale VDSL agreement signed during the quarter. In addition we reached an agreement for

OPERATING REVIEW

wholesale fibre access in Italy. In June, we launched 4G services in Spain, Australia and the Czech Republic, taking the number of markets with 4G to ten and population coverage in our five major European markets to 26%.

In our enterprise business, which accounts for 27.4%1 of Group service revenue including joint ventures, there was a 4.6%* fall in service revenue mainly due to the difficult economic environment, high unemployment and increased competitor activity in Europe. In contrast to the overall enterprise trend, our Vodafone Global Enterprise business, which serves our multinational customers, delivered a 3.7%* increase in service revenue and the number of machine-to-machine connections expanded to 11.6 million, up 39.8% year-on-year.

VZW continues to perform strongly. Service revenue grew by 7.2%* led by strong growth in accounts and rising average revenue per account (‘ARPA’) driven by increased smartphone penetration (now 64% of the retail postpaid base) and take-up of 4G services (which currently covers more than 95% of the US population).

Capital expenditure, including joint ventures1, of £1.2 billion in the quarter was higher than the previous year as we continue to extend our high speed mobile data coverage across our footprint supported by targeted investment in unified communications capability.

Free cash flow, including joint ventures1, of £1.0 billion (£3.1 billion including the £2.1 billion VZW dividend) in the quarter was flat year-on-year. £1.0 billion was spent in the quarter on the £1.5 billion share buyback, which concluded at the end of June. Free cash flow excluding joint ventures was £0.9 billion in the quarter.

Net debt at 30 June 2013, including joint ventures1, was £24.9 billion, a £2.1 billion improvement during the quarter following the receipt of the £2.1 billion dividend from VZW. Net debt, excluding joint ventures1, was £23.0 billion.

Summary and outlook

Trading in the first quarter was consistent with management’s expectation underlying the outlook statement for the 2014 financial year. The Group therefore confirms its outlook for the 2014 financial year.

OPERATING REVIEW

Northern and Central Europe

Revenue increased by 8.9% including a 3.3 percentage point favourable impact from foreign exchange rate movements and an 8.4 percentage point positive impact from M&A and other activity. On an organic basis service revenue declined by 3.0%*, primarily driven by challenging macroeconomic conditions in some markets, increasing competition and the impact of MTR cuts, partially offset by growth in mobile in-bundle revenue. Growth in Turkey was more than offset by declines in most other markets, in particular, Germany, the UK and the Netherlands.

Germany

Service revenue decreased by 5.1%*, driven by a slowdown in the market and intense price competition in both the consumer and enterprise segments. Vodafone Red, introduced in October 2012 for consumer customers and extended in April 2013 to enterprise, continues to perform in line with expectations and has had a positive impact on customer perception. More than one million customers are now on Vodafone Red price plans. Prepaid revenue continues to be impacted by the lower customer base. During the quarter we introduced a new prepaid loyalty programme with more than 450,000 customers signed up at 30 June 2013. Mobile in-bundle revenue increased by 7.0%* as a result of the growth in integrated Vodafone Red offers. This was offset by a decline in mobile out of-bundle revenue of 25.7%*.

The roll out of 4G services continued, with population coverage of 64% at 30 June 2013.

UK

Service revenue decreased by 4.5%* principally driven by continued intense price competition and macroeconomic weakness, which impacted on consumer confidence and, in turn, led to lower out-of-bundle usage. Mobile in-bundle revenue grew by 1.5%* supported by the increased take-up of Vodafone Red integrated price plans as well as continued growth in smartphone penetration and more smartphones being sold with a data bundle. Mobile out-of-bundle revenue declined by 7.0%*.

Following the integration of Cable & Wireless Worldwide plc (‘CWW’) from 1 April 2013, we rebranded the business to Vodafone and launched convergence offers to the enterprise sector during the quarter. Integration costs and synergies remain on track. Technical integration is progressing well, with several hundred UK mobile base station sites now integrated with the former CWW network and over 40% of our international IP traffic is now on-net.

Vodafone UK has continued to invest significantly in its 4G network, which we expect to launch later this summer.

Other Northern and Central Europe

Service revenue increased by 1.6%* as growth in Turkey more than offset declines in the rest of the Other Northern and Central Europe region. Service revenue in Turkey increased by 15.5%*, with strong growth in mobile in-bundle revenue, driven by higher smartphone penetration and an increase in enterprise revenue, as well as continued growth in the contract customer base. In the Netherlands service revenue declined by 3.7%* due to challenging macroeconomic conditions and intense competition, as well as lower out-of-bundle usage.

We are due to launch 4G commercial services in the Netherlands in late summer 2013.

OPERATING REVIEW

Southern Europe

Revenue including Italy1 declined by 9.1% including a 4.2 percentage point favourable impact from foreign exchange rate movements. On an organic basis service revenue, including Italy1, declined by 14.4%* primarily due to severe macroeconomic weakness, intense competition and MTR cuts, partially offset by the growth in mobile in-bundle revenue. Revenue declined in all major markets in the region.

Note:

1                  Includes Vodafone Italy, the Group’s joint venture in Southern Europe, on a proportionate basis.

Italy

Service revenue declined by 17.6%*, driven by a challenging macroeconomic and competitive environment resulting in intense price competition, as well as the impact of MTR cuts since 1 July 2012. However, commercial performance has improved both in mobile and fixed broadband. Mobile in-bundle revenue grew by 25.9%* benefitting from the increased take-up of Vodafone Red tariffs, which continue to prove popular with contract customers, as well as from higher penetration of smartphones.

Spain

Service revenue declined by 10.6%* driven by continued macroeconomic weakness and high unemployment, leading to customers continuing to optimise their spend. Competition remains intense with the increased popularity of discounted converged consumer offers in the market, which is putting pricing pressure on mobile services. Vodafone Red, which we launched in Q3 of the prior year, continued to perform well with over half the gross contract customer additions during the quarter being on integrated tariffs, driving contract ARPU stabilisation and mobile in-bundle revenue growth of 4.0%*.

Fixed revenue declined by 7.5%*, primarily due to intense competition, although our converged fixed/mobile tariffs continue to have a positive impact on the number of broadband customers, with net additions 5,000 higher than the previous quarter at 43,000.

In May 2013 we were the first operator to launch 4G services in Spain, initially in seven cities.

Other Southern Europe

Service revenue fell by 13.6%*, driven by declines in Greece and Portugal. Macroeconomic weakness, intense competition and MTR cuts resulted in service revenue declines of 17.5%* and 10.8%* in Greece and Portugal, respectively. However, both are demonstrating positive commercial momentum, with Greece adding 122,000 net customers in the quarter and Portugal growing its broadband and quad-play customers while accelerating fibre roll out.

OPERATING REVIEW

AMAP

Revenue including joint ventures1 increased by 3.7% including a 4.7 percentage point negative impact from adverse foreign exchange rate movements and a 2.0 percentage point positive impact from M&A and other activity. On an organic basis service revenue, including joint ventures1, increased by 5.9%* driven by customer base and mobile in-bundle revenue growth, partially offset by regulatory changes and competitive pressures. Growth was driven by a strong increase in India and robust performances in Vodacom, Egypt, Ghana and Qatar, partially offset by service revenue declines in Australia and New Zealand.

Notes:

India

Service revenue increased by 13.8%* driven by strong growth in mobile voice minutes, a higher rate per minute and a more stable competitive environment. Strong customer additions benefitted from improved subscriber verification processes and a number of operators reducing their presence during the previous year. Mobile customers increased by 2.7 million during the quarter.

Data usage increased by 29% compared to Q4 as a result of an increased number of data customers and increased usage per customer, particularly amongst 3G customers. At 30 June 2013 active data customers totalled 41.2 million, including approximately 3.7 million 3G subscribers.

Vodacom

Service revenue grew by 3.2%*, driven by growth in Vodacom’s mobile operations outside South Africa. In South Africa, service revenue decreased by 0.1%*, with the continued growth in data usage, driven by an increase in integrated price plans, higher smartphone penetration and the strong demand for prepaid bundles being more than offset by the impact of an MTR cut and competitive pricing pressures, particularly in the prepaid segment. Mobile in-bundle revenue increased by 4.0%*, whilst growth in mobile out-of-bundle revenue increased by 1.5%*. During the quarter Vodacom One Net, a cloud based communication service focused on the enterprise segment, was launched.

Vodacom’s mobile operations outside South Africa delivered service revenue growth of 14.3%*, excluding Vodacom Business Africa, driven by a larger customer base and increasing data take-up. M-Pesa continues to perform well in Tanzania, with approximately 5.2 million active users.

Other AMAP

Organic service revenue, including joint ventures3, increased by 0.7%* primarily driven by the growth in Egypt, Ghana and Qatar, partially offset by a decline in New Zealand and Australia. In Egypt service revenue increased by 8.2%*, despite the continued macroeconomic and political instability, due to strong customer base growth, momentum in data services and international incoming call volume and rate increases. In Qatar service revenue grew by 31.1%* driven by an increase in the customer base and growth in international call volumes. In Ghana service revenue increased by 21.7%* driven by the higher customer base and the success of data bundles. Our joint venture in Australia experienced an 8.8%* fall in service revenue as the business continues to suffer from weakness in brand perception, although network performance has improved significantly in recent months.

Non-Controlled Interests

Verizon Wireless

In the United States, Verizon Wireless added 1.0 million net retail connections during the quarter, bringing the closing mobile retail connections base to 100.1 million, up 6.3% year-on-year.

Service revenue growth of 7.2%* continues to be driven by the expanding connections base and increased smartphone penetration. 36.3% of Verizon Wireless’ postpaid accounts are now on “Share Everything” plans.

Net debt at 30 June 2013 was US$9.8 billion (30 June 2012: US$2.4 billion) after payment of a US$7.0 billion dividend to its parents.

Other transactions and developments

Verizon Wireless dividend

On 13 May 2013 VZW declared a dividend of US$7.0 billion (£4.6 billion). As a 45% shareholder in VZW, Vodafone’s share of the dividend was US$3.2 billion (£2.1 billion). The dividend was received in June 2013 and the cash has been retained in the business.

Vodafone Greece network sharing agreement with Wind Hellas

On 26 June 2013 Vodafone Greece signed an active 2G and 3G network sharing agreement covering rural areas and some urban sites. Vodafone will continue to operate its 4G network exclusively across Greece.

Adoption of new accounting standards

The Group adopted a number of new international financial reporting standards (‘IFRS’) on 1 April 2013, including IFRS 11, Joint Arrangements. The adoption of these standards has had a material impact on a number of the Group’s key performance measures including revenue, EBITDA, net debt and free cash flow, however, it has not had a material impact on the Group’s overall profit after tax. The Group issued a press release on 4 April 2013 outlining the impact of the new standards on the Group’s primary financial statements and certain non-GAAP measures for the six months ended 30 September 2012 and the year ended 31 March 2012. Restated financial information for the year ending 31 March 2013 was presented with the Group’s preliminary announcement issued on 21 May 2013.
