Jose Maria Alvarez Pallieto.
Thank you, Pablo. Good morning, and welcome to Telefonica's 4th quarter and full year results conference call. With me today is Angel Villa, Chief Operating Officer and Laura Basolo, our Chief Financial and Control Officer. As usual, we will first walk you through the slides and then we will be happy to take any questions. I would like to start by highlighting the material progress against Strategic objectives made along during the year.
1st, across our 4 core markets, Spain, Germany, UK and Brazil, We have improved our value proposition, increasing our premises pass with fiber to more than €25,000,000 in Spain and €15,000,000 in Brazil. In the U. K, the combination of O2 and Vision Media is progressing to plan, whilst in Brazil, our joint bid won the auction for Oi Mobile, which will further strengthen our market position when completed. The legal separation of Hispam was successfully completed in the year. In parallel, we continue to optimize efficiencies, increasing profitability and reducing our equity exposure.
In addition, we have announced the launch of an independent and neutral fiber network vehicle in Chile. In Telefonica Tech, Caravals are almost completed and fully functional. In the meantime, we continue to develop our digital capabilities and build our IoT and big data portfolio, Aim at range at vertical B2B markets and new cloud solutions in edge computing. We progressed as well at Telefonica Infra, Where we continue to realize value, the sale of the Telxius Towers to American Towers for $7,700,000,000 Implied a record multiple of 13.5 times pro form a OIBDA after leases and will reduce net financial debt by €4,600,000,000 Additionally, we are in advanced negotiations with a major international financial investor for the construction and offer of a neutral Independent fiber wholesale network in Brazil and recently signed a partnership with Allianz for FTTH rollout in Germany. Finally, we continue to simplify our operating model with 79% of processes being already digitalized, up 10 percentage points against last year.
We also signed an MoU with leading European telcos to promote Open RAN with successful technical testing in the UK and Germany during Q4. Moving to Slide 2 and our 2020 performance. We saw good momentum in the last quarter with organic revenue and OIBDA trends accelerating across all segments. Customer engagement improved with NPS in our 4 core markets increasing 7 percentage points versus last year and churn declining for the 4th consecutive quarter. Group OETA minus CapEx returned to organic growth at 1.9% year on year with margin improving by 0.7 percentage points.
This reflected incremental cost efficiencies and digitalization that accelerated with digital sales growing 12 percentage point versus last year to reach 31% of total sales. As a result, organic OpEx was down 2.2% year on year in the Q4 of 2020. Of particular note is the 2020 earnings per share, which stood at EUR0.24 and grew 54.3% year on year. As a result of prioritized investment in next generation networks, we now reach 135,000,000 premises passed with ultrafast broadband. Free cash flow improved remarkably throughout the year.
And we therefore continue to deleverage, reducing net financial debt by €2,500,000,000 to €35,200,000,000 at year end. This will decrease further by the additional €9,000,000,000 derived from our recently announced inorganic transactions, an amount equivalent to 25% of our year end net financial debt. Slide 3 shows our robust financial performance in a challenging year. In 2020, reported revenue declined 11% year on year, largely attributable to our favorable ForEx plans, which accounted to 6.5 percentage points of the decline, changes in the perimeter and others. OIBDA declined 12.7% year on year on a reported basis or 5.7% organically, excluding negative ForEx effects as well as changes to the perimeters and others.
Free cash flow per share increased to €0.37 in the 4th quarter, reaching €0.88 per share in 2020. Worth highlighting is that free cash flow generated in the last 5 years amounts €25,000,000,000 with 2020 free cash flow being in line with the last 5 years average despite the challenges. This cash flow stability has been a major driver in bringing down our debt by €17,000,000,000 since June 2016. Our reported results summarized on Slide 4 reflect the significant impact of COVID-nineteen, which caused a decline in revenues and OIBDA of €1,900,000,000 and €1,000,000,000 respectively in 2020. It also reflects ForEx headwinds, which reduced revenues and OIBDA by €3,100,000,000 and €1,200,000,000 respectively.
Revenues reached EUR10.9 billion in the 4th quarter, declining 2% year on year in organic terms, While OIBDA stood at €3,700,000,000 down 2.8% year on year in organic terms. We saw improving trends in our core markets throughout the year with both revenues and OIBDA declines narrowing. OIBDA Less CapEx over revenues increased 0.7 percentage point versus the same quarter last year in organic terms, again showing increased operating leverage And CapEx savings despite continued investment in high priority areas. Underlying net income reached EUR 1,000,000,000 In the Q4, growing 4.9% in 2020 and surpassing the €3,000,000,000 mark. We delivered outstanding growth in Free cash flow in the Q4, which increased by double digits to almost €2,000,000,000 lifting full year free cash flow to almost €5,000,000,000 Net financial debt continues to decline, reducing by 6.7% versus December 2019 to €35,200,000,000 Turning to Slide 5.
Q4 of 2020, year on year trends accelerated versus the previous quarter With improvements seen in both revenues and OIBDA across all segments of the business. The revenue decline narrowed by 2.2 percentage points Versus the Q3, while the OIBDA decline narrowed by 5.4 percentage points. In addition, we maintained our long track record of Gains further increasing our organic OIBDA minus CapEx margin by a 5th consecutive year on year to 20.4% at the end of 2020. Slide 6 Shows we delivered against our full year guidance of a slightly negative to flat organic OIBDA minus CapEx, thanks to effective operational management to preserve cash. We are also confirming today the final dividend for the year of €0.4 per share.
The first tranche of €0.2 per share was paid in December through a scrip dividend with 67% of shareholders opting to receive new shares, Further enhancing our financial flexibility. The 2nd tranche, euros 0.2 per share, will be paid next June through voluntary script dividend. This dividend is more than covered with our strong free cash flow per share, which stood at €0.88 in 2020. Our capacity to deliver to society was challenged as never before in 2020. We were able to Our business performance by keeping our ESG performance at the center of our strategy, which is based on 3 pillars, to help society thrive, Build a greener future and lead by example.
For the first pillar, we continued our significant contribution to the countries in which we operate, 0.5 percent of GDP as well as almost 1,000,000 jobs. We also made significant tax contribution of €8,200,000,000 And we kept delivering on our already ambitious and fundamental agenda, beating our targets and setting new ambitious ones aligned with the required urgencies of climate change. We reduced emissions by 61%, while continuing to Thanks to our network transformation plans. We have also contributed more than ever to the decarbonization of the economy, Thanks to the increase of digitalization during the COVID-nineteen crisis. The group has also delivered sustained improvement in other ESG metrics.
Our customers and society in general valued our rollout performance through the pandemic. And our reputation measured through RepTrack reached a record of 66, 10 percentage points over last year. Looking at gender diversity, we achieved an increase of 1.8 percentage points to 27%, Something I'm proud of considering this figure was below 20% 5 years ago. Among the range of ESG awards and recognitions we received throughout the year, I want to highlight for the 2nd consecutive year, we lead the ranking of digital rights, which is a prestigious third party reference. Finally, Telefonica is committed to achieving net zero emissions in our 4 main markets by 2025.
I will now hand over to Angel to go through a detailed review of our business performance.
Thank you, Jose Maria. On Slide 8, we show the performance of the Spanish business. During Q4, we took steps to cool down pricing competition, Enabling us to continue with our more for more strategy. We announced the fiber speed upgrade to 1 gigabit per second And agreements with DAZN and Disney Star to include their premium content in our offer. These actions temporarily Lead to lower gross adds and muted KPIs, but do deliver positive results in terms of churn and value mix And add further sustainability to our business.
By year end, the convergent base remains stable. ARPU improved in the second half of the year and churn was reduced year on year. Hence, the value of our convergent business has grown even with the toughest macro environment in decades. In addition, we have the largest fiber to the home network in Europe, with the uptick reaching 29% As a result of higher accesses connected in both the retail and wholesale businesses. Continuing with Spain, let's move to financials on Slide 9.
Service revenue accelerated its improving trend sequentially Across all revenue lines and especially in the second half of the year, mainly on the back of a solid convergent ARPU And record IT sales. Continued cost containment and benefits from digitalization Led to an improved OIBDA trend quarter on quarter with an OIBDA margin of almost 41% in 2020. On the investment front, and despite having rollout more than 2.1 fiber to the home premises And switch on 5 gs to cover 78% of population, 2020 CapEx declined to 11% of sales. As a result, Telefonica Spain proved once again its ability to deliver solid cash generation Amid very challenging conditions, with an OIB minus CapEx of €3,600,000,000 virtually flat year on year. Finally, we are committed to achieving net 0 emissions in 2025 in our Spanish operations.
Moving to Slide 10, Telefonica Deutschland maintained its strong trading momentum in Q4, With the O2 Free portfolio continuing its good traction, an O2 contract churn registering Historically low levels at 1%. Our improved perception amongst customers It's a result of a successfully equalized network quality as the company met all its LTE coverage obligations. In the current mobile network test conducted by Trade Magazine Connect, the O2 network secured a very good rating for the first time, Reflecting the enhancement in network quality driven by the 4 gs rollout. In terms of financial performance, Telefonica Deutschland met all its full year revenue, OIBDA and CapEx to sales guidance. Network development and targeted customer focus continue to drive growth momentum, With revenues increasing 2.7% year on year in the Q4, while STAIPTA growth continued to improve strongly, Up to 3.4% year on year in Q4 versus 0.7% in Q3.
Full year CapEx increased by 4.8%, driven by investments for future growth in 4 gs and in the 5 gs launch, Now active across 15 cities. And in terms of our sustainability efforts, Telefonica Deutschland State to gain is to be carbon neutral by 2025. With 5 gs consuming 90% less energy per byte than 4 gs, We are very well placed to reach this target. Turning to Telefonica UK on Slide 11, We continue to be the U. K.
Number 1 network. We have grown our base by 5% to reach over 36,000,000 mobile customers With market leading NPS and customer loyalty that continued to improve in 2020. Looking at the financial performance, top line trends have been adversely affected by COVID impacts. However, With solid trading in the 4th quarter, we saw improvements in mobile revenue from hardware and SME, containing the total revenue decline in 2020 to 4.4%. OIBDA grew by 2.5% year on year in Q4, while declining by 2.4% in the full year 2020.
It is worth highlighting that this is the 5th consecutive year Of margin expansion in the UK business, driven by our flexible operating model and continued efficiency gains. OIBDA minus CapEx grew by 2.7% year on year in 2020 as a result of strong cost control And CapEx flexibility with an increased focus on growth areas such as 5 gs. In line with the group's ESG agenda, Telefonica UK has committed to become the 1st UK mobile network to achieve net zero carbon by 2025. I am also pleased to say that the O2 UK Virgin Media joint venture is progressing to plan, and we expect it to close around the middle of this year. This transaction values our 2 UK at 7.8 times for EBITDA and will create the UK's connectivity With a joint enterprise value of £38,000,000,000 with an expected cash inflow for Telefonica Of £5,500,000,000 to £5,800,000,000 subject to customary adjustments in this type of transaction.
Let's now move to the performance of our Brazilian operations on Slide 12. In 2020, we have reinforced Our leadership in mobile with a record 33.6% market share and accelerated our transformation to fiber. In contract, we added 729,000 new accesses in Q4, following a more for more strategy And thanks to the increasing demand for high quality and reliable services. At the same time, churn improved to 1.1%. In fixed, we passed almost 5,000,000 premises with fiber to the home during the year, Doubling what we did in 2019 for a total of $16,000,000 We want To continue capitalizing on the fiber opportunity, using different models to address different profiles.
In line with this, we are in advanced talks to create a neutral wholesale fiber network vehicle Where both Vivo and Telefonica infra will hold equity stakes, targeting more than 5,500,000 premises passed in 4 years. Looking at our financial performance, we delivered outstanding OIBDA minus CapEx growth of 8 point 5% versus 2019, with a margin expansion of 2.5 percentage points. This outstanding result was supported by our continuing focus on driving OpEx efficiencies and optimizing capital allocation. On top of that, the acquisition of Oi's mobile business is progressing to plan, with closing expected in the second half of twenty twenty one. This will further enhance Vivo's position in the market, allowing us to deliver even higher service quality while creating significant value through synergy generation.
Finally, on the ESG agenda, Brazil is committed To achieving net 0 emissions in 2025. Moving now to Slide 13, Celsius continued to deliver a strong performance, demonstrating the resilience of its business model throughout the COVID-nineteen crisis. In the tower business, the portfolio increased 46% year on year with a number of 3rd part tenants up 15%, Driving both organic revenue and OIBDA growth above 40% year on year in the quarter. In the cable business, a second round of contract extensions with relevant clients was executed, resulting In an increase in net full contract value in the semester of approximately $620,000,000 Despite a consequential short term negative impact on revenues and OIBDA. As a whole, Telxius delivered accelerated year on year revenue and OIBDA growth of 11% 13%, respectively, in the quarter.
While the division's OIBDA minus CapEx margin reached 46.9% for the full year. On top of this, Telefonica Infra successfully crystallized the value of our assets. Last month, Telefonica Infra announced a landmark Agreement with American Tower Corporation for the sale of Telxius Tower Division in Europe and in Latin America, as Jose Maria mentioned at the beginning of the presentation. Slide 14 shows how Telefonica has been Focused on pursuing value creation opportunities in fiber. Telefonica's footprint has grown exponentially in recent years, Reaching almost 50,000,000 fiber owned premises passed in 2020, additionally, including our wholesale agreements, Our ultra broadband footprint reached 135,000,000.
Penetration of ultra broadband connections, Our total fixed broadband accesses rose to 77%, that is 6 percentage points more than in 2019, Driven by a strong technological transformation that provides visibility to long term revenues. In Germany, as announced last October, we've signed an agreement with Allianz to create a neutral wholesale operator Called Unseregrune Glazfasser, which stands for our green fiber in German. This new company has received Approval from the European Commission with construction starting this year and a plan of passing more than 2,000,000 premises in 6 years. In parallel, in Chile, we've announced the creation of a vehicle called InfraCo, which will also enable us to accelerate fiber deployment With no CapEx impact and reach 3,500,000 premises passed by the end of 2022. Telefonica Chile will contribute its footprint of 2,000,000 premises passed at a very attractive 18.4x CV to OIBDA, While holding a minority stake of 40% in the company, while KKR will hold 60%.
This transaction is expected to reduce net debt by $400,000,000 And in Brazil, We are in advanced negotiations with a leading international financial investor for the construction of a neutral independent fiber optic wholesale network. The new company, Fibrasil, that will also have the participation of Telefonica Infra aims to accelerate expansion of fiber to new locations Through a CapEx light model for Telefonica Brasil and capture value through third party penetration. Telefonica Brasil is carving out 1,600,000 brownfield premises passed into fiber Brazil, and the target is to reach Over 5,500,000 fiber to the home premises passed over the next 4 years. As you can see, Fiber to the home networks are fast consolidating their position as a core infrastructure asset class With buoyant M and A activity at very rich valuations across geographies. Therefore, we have optionality To continue exploring further growth and value creation opportunities across our footprint.
Turning to Slide 15, revenues from tech services that is cloud, cyber and IoT and big data Grew consistently by 13.6 percent year on year in 2020 to €1,500,000,000 And proving to be the fastest growing and most resilient business despite the challenges posed by the COVID-nineteen crisis. It is important to highlight the competitive integrated portfolio, the strong operational capabilities, extensive commercial reach And its large base of B2B customers. Growth was mainly fueled by the corporate segment, Where Telefonica plays a key role in driving digital transformation, thanks to the company's unique ability to address The converging demand for cybersecurity and cloud services. Telefonica Tech companies are already established and running With close to 50% of revenues already transferred to them, the new structure will help us to capture revenue growth and efficiency gains ahead. So we met our targets and have outperformed the market once again.
I will now hand over to Laura to cover The financial results.
Thank you, Angel. Turning to Hispam on Slide 16. Our focus remains on reducing exposure to the region without jeopardizing growth, thanks to alternative investment models that have been implemented in the last few quarters. Thanks to both this extra focus on value growth and our differential assets in the region, Contract accesses and fiber connections show a very robust performance at record low churn levels. Sound commercial performance in value segment has was then coupled with efficiencies, fostered by acceleration in digitization and CapEx They allow us to post OIBDA minus CapEx growth versus 2019 despite the tough year.
Let me highlight, we are reducing significantly the average capital employed, close to 20% versus 2019, Deveraging on an asset light model through co investment deals with ATC and ATP, the announced InfraCo in Chile, 4 gs serving in Colombia and AT and T agreement in Mexico for infrastructure rationalizations among others. In addition, our capital structure improved with significantly increased leverage in Colombian and Chilean pesos, respectively. And finally, we are crystallizing value through disposals as demonstrated by the Central American sale, Last on tower sales to ATC and the announced infraco in Chile. Slide 17 So how FX headwinds are mitigated at the free cash flow level through our natural hedge. The impact of FX in the 4th quarter was lower than in Q3.
In 2020, FX detracted 6.5 percentage points year on year from revenue growth and 8 percentage points from OIBDA, mainly due to Brazilian real depreciation versus the euro. Nevertheless, the negative impact of €1,200,000,000 at OIBDA level Translated into just €231,000,000 at the free cash flow level. On the other hand, FX had a positive impact of net debt Of as much as €1,000,000,000 in 2020, which increases further to €1,800,000,000 if we include leases. On Slide 18, you can see how strong free cash flow generation was last year, topping €4,800,000,000 And comfortably allowing us to cover dividend, hybrid coupons and commitment, while helping to bring down net debt. We paid down €2,500,000,000 to €352,200,000,000 as of December 2020.
Once we take Telefonica's recently announced strategic and inorganic initiatives into consideration, net financial debt We'll decrease by an additional €9,000,000,000 to the €25,000,000,000 mark. And we remain committed to reducing our net debt going forward Through solid organic free cash flow generation as proven even during the worst operating environment in decades and further inorganic measures. Slide 19 shows our proactive and innovative approach to financing in 2020, navigating A volatile market to raise €17,900,000,000 in total, including €6,300,000,000 related To the Virgin Media O2 UK deal financing, we have been at the forefront of ESG financing as the first ever telco issuer to tap The green hybrid market and more recently as the 1st telco to issue a sustainability hybrid bond. In addition, we have reduced our maturities to 2022 through €2,000,000,000 equivalent Of liability management exercises in 20202021 to date. And we have extended our average debt life to close to 11 years, While maintaining a robust liquidity cushion of €21,400,000,000 which comfortably accommodates upcoming maturities.
Should we include the recently announced inorganic deals, our maturities will be more than covered for the next 3 years. All these financing activity has been executed at historically low interest rates, enabling us to reduce Enabling us to reduce our effective interest cost to 3.11% as of December 2020,
Thank you, Laura. 2021 guidance, we report expectations So this is going forward, and this is like anticipated and recorded for 2021. We will continue to manage our resource according to results evolution. On dividend, we are announcing €0.3 per share for 2021 to be payable through voluntary scrip dividend In December 2021 June 2022, our decision to adapt the dividend allow us to combine the need for financial flexibility in a year Where several spectrum auctions concur with expectations of a strong free cash flow generation and significant inorganic transactions and still Want to incentivize our shareholders and provide them with attractive, quite sustainable returns. And now to conclude, I'd like to leave you with a few takeaways from today's results.
First, we have proof of our resilience in challenging times during 2020 And continue to deliver for all stakeholders. We delivered on our 2020 guidance and proved our cash preservation capabilities while strengthening our Positioning. 2nd, we executed material progress towards our strategic objectives with reduced exposure to Hispam, Value creation and realization from infra and tech as well as significant development across our 4 core markets. Again, we sold our towers at the highest ever multiple, both for the industry and in Telefonica's history. These achievements help us deliver significant progress in deleveraging, both organically and inorganically.
Once the inorganic bills Have been completed, net debt will be further reduced by as much as €9,000,000,000 or 25 percent of year end debt. And finally, we are announcing a positive outlook for 2021 and dividend of €0.3 per share.
Okay. So Georgios is asking us about fiber. He says that we have already done the deal in Chile, and we have the one in Brazil on the way. The question is, if the plan is to maintain the control in Brazil and what other options we have for similar deals in other Chris in his time. This will be the first question from Georgios.
Thank you, Georgios for your question. We are announcing different formats of fiber deals depending on the objectives and the market conditions. The deal that we announced in Germany is a deal of co control to grow from a greenfield Point of view in Germany, it's a deal structure, 50% Allianz and the 50% Hoehl by Telefonica We'll be half Telefonica Deutschland and half will be Telefonica Infra. The aim of that deal is to grow in a greenfield manner. Then the deal in Brazil is a different format of deal.
We have Divided the country into 3 tiers of towns and cities. Tier 1 is going to be developed with our own CapEx. This will be 100% owned by Tefonica Brazil. Then there is a second tier that we are Addressing through either agreements with fiber owners like American Towers that we deminaturize or with And the projected vehicle, fiber deal, where we will have core control with a partner, 50% will be owned by the partner, 50% will be split equally between Telefonica Brazil and Telefonica Infra. This is a deal which is slightly different from the German one because it has a brownfield component.
Beboe will contribute 1,600,000 Premises and the rest will grow via Greenfield and potentially through acquisitions to reach €5,500,000 in the next 4 years. There could be other fiber deals in Hispanoamerica. We just announced The deal in Chile, but these are countries where the fiber penetration is still Not as high and there are opportunities to create value in the region.
And by Virgo, we are very satisfied. We have created the largest neutral wholesale operator in Chile, we have also maximized valuation. As you know, the enterprise value is above 1,000,000,000 Dollar and that results in a multiple of over 18x8. Moreover, We will be having a 40% stake in an infraco, which will have greater value For the future, this is serving many of the targets we have around Ispan, which is modulate exposure, but at the Same time, go back to profitable growth, which we have already managed in 2020 despite the difficult conditions And create a continued contributing to net debt reduction, and this transaction is going to reduce Net debt in approximately EUR 400,000,000. I think there's some read across this transaction Because I need the great value of our infra assets.
If you look at the ultra broadband premises passed in Isban, Those are over €12,000,000 And if you think we have been selling this at around €500 per home, That would imply a total value just for the fiber in East Bank of €6,100,000,000 just extrapolating that, which is Well above, which is the consensus right now for Hispania is around €7,700,000,000 So I think the opportunity and optionality here is huge. And at the same time, this is compatible with continuing growing profitable in the region.
Thank you, Laura. The second question from Georgios is about fiber and spend. Is that something if it is that something that you consider? And what are the considerations that would prevent us from taking similar decisions, understanding that you don't need greenfield funding, but it can help with the leveraging.
Well, our operation of fiber in Spain is very well developed. Spain is a highly penetrated market. It's leader in Europe. It's a market where we have already several commercial agreements in place to wholesale the fiber. As you said in your question, there is not the greenfield opportunity that we see in the places that we are setting up new fiber cost with partners.
We have a very valuable and very well developed fiber in the country, which is for us strategic. It's optionality for the future, but we are not contemplating at this stage Transactions regarding the fiber, it's strategic.
The next questions came from Mandeep. Mandeep is asking Mandeep from Red Bull, Mandeep Singh. Asking in Spain, if there is any Prosegur revenue contributions in the Spanish revenues, Any revenues coming from the joint venture with Prosorb? And how much? And if there are benefits from copper sales, I understand the central offices in EBITDA.
And the second question is regarding UK spectrum. If Tev will bear the cost and then contribute it to the joint venture.
Thank you, Mandeep, for the question regarding Prosegur, the joint venture is 50%, 50% owned. It's account by Telefonica Spain as per the equity method. So it does not consolidate the ETA from the Prosegorsion Venture neither the revenues. Yes, Telefonica Spain is Accounting in its figures, the commercial commissions from selling to our customers those alarms That are being supplied by the Proseo Gorgiou venture. So partially, the results are included in the terms of the commercial fees that Spain gets From selling those, the results of the alarm activity itself is accounted through equity method.
Regarding copper sales, We continue to decommission our legacy copper switches. This is allowing us To undo investments that we have in our perimeter, be it through selling real estate, which has been more active In prior years than this year and also regularly selling copper sales, which are accounted as other revenues In Telefonica Spain numbers. Regarding the UK spectrum, the auction is expected to start in the month of March. It's it has 2 tranches of spectrum being sold. Since the JV has still not closed, this is a process that will be run single handedly by Telefonica And the cost will be borne by ourselves and then the asset will be contributed into the JV.
Okay. The next question comes from Michael Bishop from From Goldman Sachs. The question is about free cash flow. Michael says, given the strong beat in 2020 versus your guidance of more than €4,000,000,000 Do you have a similar guide or ambition for 2021, given consensus is only at €2,500,000,000 free cash flow 2021?
Thank you for the question. We do not guide on free cash flow, although we remain Focus on delivering a very robust free cash flow as it's been the case in 2020 And also hope to beat the consensus as it's been the case in 2020. Let me tell you that free cash flow is an absolute priority And we expect it to comfortably exceed dividend payments, the labor commitments and the hybrid coupons payment and will continue To be a sustainable driver for continuing deleveraging. I will elaborate a little bit, although it will not be guidance, as I said at the beginning. But if you start from our operational guidance, we are expecting recovering and normalizing trends that will be more evident from Q2.
Those will stabilize and also CapEx to sales will trend back to normalized pre COVID level up to 15% of sales. This will put some pressure on operating cash flow year on year, but will allow to continue capturing future growth. Below operating cash flow, we will continue with our business as usual working capital measures. We will optimize And continue optimizing our financial payments with our strategy that consider cost, but also life currency and liquidity needs. For tax payments, we have a midterm guidance of 20% with the unavoidable volatility around advanced payments and refunds.
In that sense, in 2020, we had some positives such as spectrum auctions being delayed for 2021, low level of payments in advance And also, as you know, we successfully hedged free cash flow and that also flew through financial payments. But you can count on us managing every single line Starting from stabilizing operational trends and optimizing all other financial items. And of course, CapEx and resources in general, There's still uncertainty surrounding COVID-nineteen and how the pandemic will develop is a risk going forward. And despite anticipating Covering for 2021, we will definitely continue managing our resources according to results evolution. All in all, we have proven resilience in challenging times, and we have many levers to maneuver.
And we are closely monitoring our Free cash flow generation, and that will be the same in this year. We keep on improving efficiency and prioritizing our investments to adapt our expense Towards revenue and profitability generating sources, we will continue working in this direction, Michael. Free cash flow generation is a priority for us.
Then the next question is from Mathieu Robilliard from Barclays. Mathieu is asking about the business in Spain. If you can discuss recent competitive trends in Spain and what it will take to stabilize the top line and when?
Thank you, Mathieu, for the questions on Spain. In this quarter, Telefonica Spain has shown market leadership By deliberately reducing commercial pressure during the first half of the quarter, we have been Deliberately cooling down the market since late Q3, offering lower discounts and shortening promos. We were the 1st mover and this has penalized our gross adds by early Q4, but other players followed us. The Q4 campaigns, the Black Friday, Christmas have been softer than previous years. The promotions that could have been By some players, 50% for 6 or 12 months now are generally reduced to 3 months promos.
And we have seen not only Q4, but also now that in February, all promos in unlimited mobile data have been removed by all players. And for instance, Orange is decommissioning some of its lower end brands. This has allowed, as I was saying in my speech, To enable More for More initiatives, we saw that from Vodafone in November, from Uskaltel in December and ourselves also in January 2021. This decision, which was on purpose to cool down the market and had to be exerted by the market leader, Will still hit us in our commercial metrics in Q1 because of expiration of promos, But clearly, it's paying off in terms of market repair, it's paying off in terms of lower churn and it's paying off in bringing in high value subscribers. Churn has improved month over month in Q4 for all segments.
The convergent gross adds mix Has improved sharply. 74% of the Fusion gross adds in the second half of the year Are in the mid to high end, that is 19 percentage points more than in the first half of the year. And ARPU is virtually stable Quarter on quarter and the year on year trend is improving. So as you have seen, these results Are allowing us to improve our revenue trend, are allowing us to comply with what we have been Stating that ARPU in the second half would be higher than in the first half and also with cost control and efficiencies Have allowed us to have OIBDA margin higher in the second half than in the first half. Then Your second question was regarding revenue stabilization.
What we see, and again, this is the outlook for Spain and This is not a guidance and should not be taken as such. And of course, it's highly dependent on the evolution of the pandemic. What we see is that the sequential revenue recovery trend has clear momentum. We have been able to sustain the convergent base with growth in contract mobile and fixed broadband, Especially in fiber. We are launching some more formal actions.
We are getting traction from new digital services, This in B2C, but in B2B what we see is that we have achieved record growth in IT services That far more than offset the communications erosion. Roaming should be recovering as the pandemic recedes And wholesale will continue to be strong. All of these trends are supporting revenue in Spain Towards stabilization or even slight growth for 2021. At the same time, we're expecting our EBITDA margins to be around the 40 And CapEx to be benchmark around or up to 12% for the Spanish operation. Also related to Spain,
there are questions coming from Jacob, the Bluestone from Credit Suisse and Joss Mills from Exane. I think that there have been already covered part because Jacob is asking about the outlook for spend in revenues and EBITDA, But also regarding what we see ahead in terms of subscriber evolution. This same question regarding the evolution of subscribers And the changes between high and low value is being asked by Yoss Mills And how we see in relation with this, we continue to see value In content, in football content, in sports content in general, to continue including it In our offer. And if we would perhaps offer more football content to lower end subs And if this changes our view on how much this content is worth ahead of upcoming auctions? Thank you, Pablo, for your 27 questions.
Okay. On the outlook, I think that I elaborated. We see sequential recovery trend in revenues to have clear momentum, which should support for the factors I responded before stabilization or even slight growth in revenues with the margin OIBDA being Around 40%. I should add to what I said before that the second half will be better than the first half given the comps and the evolution across the year and CapEx To be below 12%. The question was also about the perspective for evolution Of KPIs, again, we are deliberately working at cooling down the market.
We are with a clear strategy of going for value, not for volume. Others may choose to go for better cosmetic KPIs at the expense of financials and sustainability, that is not our case. And here, we are in the high end focusing on retention and the low end, we are focusing on acquisition. On the football or on the content, football again has proven to be A commercial engine in the high end, especially in COVID times. We have been growing in high end subs.
As I was saying before, in the gross adds volume, the mix has been excellent. In the second half of the year, three quarters Of the gross adds have been in mid to high end. This has allowed the convergent ARPU to improve. I should also say that football gross adds in the second half have been double the ones of the first half. And we have also been able to get an improved ARPU in the second half than in the first half.
I don't know if I responded to several elements of your question, Pablo.
I think you did. Then Carlo Murog Smith from Berenberg is asking about the dividend and the guidance. On the dividend, he says, Can you talk about the logic of cutting the dividend, but maintaining passcode option? Surely, it would make more sense to cut the dividend to a sustainable level and pay it in cash, then rebuild from there. How would you react to the acquisition of that Persistent use of a scribe option like a series of mineral rights issues.
And then on guidance, on what does mean what does Stabilization mean, in numerical terms, there are two ways to think about the stabilization, something around 0 Also, I think closer to 0 than 2020 trend. And he thinks That the right one is the first one, a kind of minus 1 to plus 1 range.
Well, thanks for your question. Taking the first one on the dividend, the decision of proposing a dividend payment €0.3 per share in a voluntary scrip option is based On the following framework. First, we really want to speed up our internal transformation process, and therefore, we want to preserve A strong free cash flow generation and at the same time being able to invest in the growing part of our business in our business. The second one, keep in mind that we will keep exploring inorganic options, but and that's helping us to
reallocate capital in Two growth areas
and at the same time to reduce leverage. I mean, we will be closing transactions during this year likely That would represent more than €9,000,000,000 of additional debt reduction or additional funds flowing through the business. In 2021, It's a year in which we will be most likely facing spectrum auctions in 3 of our 4 core markets, I mean, Spain, the UK and Brazil. And we are still surrounded by some degree of uncertainty around COVID-nineteen impacts and therefore, though the outlook is positive. And keep in mind that we want to preserve a sound investment grade rating.
Taking all this into consideration and adding that we I think that it is important to preserve an attractive level of shareholder remuneration. We think that EUR0.3 per share meets all the targets. It reinforced the company, both Strategic and financially, it provides flexibility in uncertain times. It accelerate the leverage and it provides An attractive return. In terms of the preserving the scrip option, We think that through our voluntary script, we have been able to keep some flexibility and at the same time, Offering greater optionality to our shareholders.
Remember that twothree of our shareholders decided to reinvest their dividends. We think it's important to keep that flexibility once the outlook is still affected by COVID-nineteen. Keep in mind as well that any excess free cash flow We'll be devoted to neutralize the dilution. And in year 2020, we have partially offset the dilution by canceling 1.6% of the share capital. And therefore, the share buybacks are going to be used as a tactical tool to control those level of dilution to adapt to the excess Funds coming from M and A, when we are able to preserve sound investment and grade rating.
And therefore, in summary, we think that it It implies more flexibility and at the same time, it can help us to accelerate our strategic transformation. In terms of the guidance, for us, stabilization Means that we see better trends. As Angel has been describing in some of the markets, namely in Spain, we see better trends growing up. I mean, and we have Momentum in operational trends, but we still have some uncertainty surrounding COVID. COVID should be COVID effect should be fading away all along the year And that has significant impact in places like roaming or SMEs revenues or B2B or handset sales.
And therefore, we see a progressive improvement in the metrics. So for us, stabilization mean close to stable, mildly positive, mildly negative.
Thank you. Then, Georgi Roya from Deutsche is asking 2 things. 1, the first and the first question is, Could we have an update on the timing of inorganic actions in LATAM? Any views on how you are thinking about disposals versus spin off? And the second is, can you please help us to understand better the Q4 Spain retail revenue?
You mentioned stronger support from IT revenues and improving trends in non convergent revenues. Any more color on what the extra support from IT revenues was will be helpful. And if the nonconversion revenue improvement, if this is sustainable?
I'll take your question on LATAM. In November 'nineteen, we established as a strategic priority to reduce our exposure to LATAM In order to mitigate our exposure to FX volatility, during 2020, a lot of things have been done. First, as Laura has been saying, we have moved towards an asset light model. We have been Doing a very selective CapEx allocation towards growth, we have become an MVNO in Mexico. We have accelerated network sharing agreements like the one that we have in Colombia.
We have reduced capital intensity by selling towers and monetizing fiber assets and all those divestments have been done at very attractive multiples. In the case of the divestment of Central America, above 6x OIBDA and in terms of towers of fiber assets in the high teens. In order to give you an example, as Laura was mentioning before, the fiber transaction in Chile has an implied value of per home pass of $500 And that means that we have significant optionality because we have 12,100,000 home pass in LATAM. We have also increased debt in local currency significantly. And as a result, we have reduced capital employed in Latin America during 2020 by more than 20%.
We are moving into a lighter asset model, More naturally hedged structurally and more easy to hedge in terms of free cash flow growth. We will certainly keep exploring inorganic transactions, But only if it creates value for Telefonica shareholders. In the meantime, we'll manage the region according to our So the priority to reduce capital exposure to LATAM.
Thank you. Then Excuse me, Pablo.
Yes, regarding the Spain retail revenue trends, let me try to give you some more color. The 4th quarter revenues in Spain declined by 2.9% year on year. This rate is 1.5 percentage points better than in Q3 And would have been a positive 0.5 percent ex COVID impact. If we decompose it between handset And service revenues, handset sales continued to have a weak evolution of minus 24.5% in the quarter, It was minus 26% in the 3rd quarter, so still weak, while service revenues at minus 2.1% year on year Have improved 1.5 percentage points versus Q3 despite roaming and lower comps Because we have had other impacts quite positive like IT in the B2B segment, record growth at 23% year on year. We have also had new digital businesses impacting and also wholesale has been quite positive.
The tariff upgrade has contributed as well to this revenue improvement. So if I were To decompose the acceleration or the improvement of trend between Q3 and Q4, the softening of COVID impacts Has been helping us. This IT reactivation to record high as well. We have had Better performance of the consumer nonconversion revenues, far lower decline than previous. And wholesale has been strong, but a little bit of a drag from some of the wholesale revenues.
All in all, ex COVID, the top line in our Spanish operation would have increased 0.5%.
Then Sumit from New Street also has questions regarding the Spanish business fee, Ask if we can provide an update on thoughts on the European recovery program implications for Spain and Movistar. And if we have an idea of potential timing of this process during 2021.
Thank you, Sameet, for the questions. The Spanish government has already announced and set up plans For the European recovery funds, which will be to the tune of €140,000,000,000 for Spain In the next few years. Those have to comply with the priorities that have been set up by the European Union, And we see opportunities in the digitalization axis and also in the environmental Axies, given that many of our new investments are going to go in the direction of net 0, our net 0 target in 2025. This digitalization areas will amount To €20,000,000,000 overall figure, this is more than the 20% European community threshold for digitalization, so good news. We Are already making specific proposals to benefit from these funds, and we think that we are best positioned to make the most out of these subsidies.
Materialization of this would be later in 2021 and then in the years to come. So we see high chance of Telefonica benefiting from these measures. But as soon as They become more precise, we will be able to factor them in our outlooks.
I think that we have to finish, but I think that we have some one final question because Fernando Cordero and Fernando Abril from And Andrea and Alantra were asking about Spain and Espana, but I think that all the questions they have had been already answered. And Achille Dattani from JPMorgan. He's also asking about infrastructure that I think has been already answered, the Spanish KPIs That has been already covered. The guidance and what the stabilization means that has already been covered. And but he has another question that I don't think has been covered, which is the Spanish consolidation.
Akhil says there is a lot of speculation in the market at the moment Of our Bola Formats Mobile deal. Should a deal materialize, how do you think it impacts your retail and wholesale outlook?
Well, first, let me framework the question and then I will pass it over to Angel for the detailed Operational impact. We think consolidation is welcome. It makes no sense that there is so much Pleasures in Europe. I mean, just to give you 2 specific references, average revenue per access in Europe It's half average revenue per access in the U. S.
According to analyst Mason figures. And also investment in 5 gs per capita In Europe, it's something around €94, while it is €150,000,000 in the U. S. So I think that Consolidation makes sense. Intramarket consolidation makes sense, and we will certainly support that if that was to happen in Spain.
Just not sure that there is much more to add. Current market structure seems hard to sustain. This seems to be a consensus view now and look like a solution is needed in market consolidation maybe 1. We have always said that we are supporters of the market consideration. And if this were to develop, we would be supporters.
So thank you very much all of you. Apollo EIs for the technical problems. I've been in 46 quarterly calls and This never happened. This is the last one, and something had to happen. Now let me turn the call over to Jose Maria to finish the call.
Before concluding, there is something important to say. I would like to thank Pablo for his great contribution, Commitment and dedication during his 10 years heading the IR team. I know it has been tough, but he was totally up to the challenge. Now it's time for him to assume new responsibilities within the group. And he has been appointed Chief Financial and Control Officer of Telefonica Tech, which is our fastest growing unit.
I'm sure he will excel in his new role as he has always done. Thank you very much for your participation, And we certainly hope that we have provided some useful insights for you. Should you still have further questions, we kindly ask you to contact our Investor Relations department. Good morning, and thank you.
