Operational Review

Total RGUs grew by 2.2% yoy to 9.570 million with an acceleration in net adds in 3Q18 to 70.3 thousand compared with 42.0 and 45.9 thousand in 1Q18 and 2Q18 respectively.

Fixed pay TV net adds posted a marked recovery to 10.6 thousand in the quarter, the highest level of net adds since 1Q17, reflecting the anticipated commercial acceleration from new household coverage combined with a continued improvement in churn levels. In 3Q18, fixed network coverage increased by a further 98 thousand households bringing year to date expansion to 176 thousand, and with total coverage reaching 4.257 million households. 888 thousand households are already in FttH and the remaining HFC households are 100% upgraded to Docsis 3.1, therefore providing Gigabit capabilities across the entire footprint. Fixed broadband and voice RGUs also recorded an improvement in 3Q18 led by the growth in pay TV subscriptions which are the basis for upselling other additional services in the residential market. Regarding the DTH customer base, with the additional NGN coverage from all operators in the market, the number of services continues to post a downward trajectory with customers migrating to greater bandwidth fixed access technologies, as is to be expected given the more sophisticated offers provided.

Mobile subscriptions had a good quarter with summer seasonality driving higher net adds of 41.9 thousand and taking the total customer base to 4.770 million. The majority of new customers are subscribing as post paid accounts, 57% of the total base, and many of which within convergent bundles.

During 3Q18, the number of customers subscribing to convergent offers increased by 5.8% yoy to 759.9 thousand, 49.9% of the fixed subscriber base. Offers for the consumer market are available for all pockets and demand profiles with offers ranging from an entry level, content light, 100 Mbps triple play offer for set top box) going up to a convergent, 1Gbps, 177 channel quad play offer including 1 SIM card with 10 GB of The ability to provide 1Gbps nationwide became possible with the full Docsis 3.1 upgrade in the first months of the year, thus giving customers 1Gbps download speeds across the entire footprint, be it over FttH or HFC.

Residential ARPU was relatively stable on a quarterly basis at 44.2 euros and lower yoy by 0.8%. However adjusting for regulation, including the 44% decline in Mobile Termination Rates (MTRs) in 3Q18, ARPU would have marginally declined by 0.2% yoy to 44.1 euros.

In the large business segment we remain focused on protecting our revenue in existing accounts whilst driving upsell of additional data and IT service management solutions. The skills and experience we have acquired in our own operations, together with the significant increase in data centre capacity, are being levered to provide more sophisticated next generation cloud management platforms to facilitate provisioning and self-service solutions for the enterprise market. The small business segment remains challenging in terms of revenue progression however efforts are being made to optimize and simplify our business operations to guarantee increased efficiency and customer service levels.

Technological and Operational Transformation to guarantee long term competitiveness

We are well ahead with our mobile investment to single RAN architecture with 75% of the upgrade to be completed by the end of the year and the remainder during early 2019. We are deploying the latest available mobile technology and the upgrade will position us with the best network capabilities in Portugal, significantly increasing capacity, flexibility and quality of service whilst also leaving us as ready as technologically possible for a smooth transition to 5G when required.

As mentioned above, we are deploying additional FttH to greenfield locations within the context of our dark fibre swap agreement with Vodafone. During 3Q18, fixed network coverage increased by 98 thousand households bringing total fixed coverage to 4.257 million households of which over 20% are already FttH, aligned with our long term plan to reach 70% FttH coverage by end 2022.

Visible progress is being made within our operational transformation programme with initiatives from the first wave (out of three in total) already moving to implementation stage such as STB recovery procedures and robot deployment throughout the organization. The coming months will see a number of wave #1 projects streams leaving the drawing board to move to live implementation and starting to impact operational efficiency and service levels during the course of 2019. Organizational fitness, customer satisfaction and operating efficiency are core goals of the programme which is set to run until the end of 2022, with an acceleration in ramp-up of the value captured once all 60 projects are live across the company from 2020 onwards.

Cinema and Audiovisuals

Our cinema and audiovis Q18 reflected the wordwide decline in cinema spectators, despite a performance.

In 3 5.2% to 2.378 million, reflecting the negative performance of the market as a whole due to fewer blockbuster box office hits during the quarter in comparison with 3Q17. After an exceptionally strong 2017, performance for 9M18 has returned to levels similar to 2016. Average revenue per ticket improved by 4.0% yoy to 4.9 euros in 3Q18. The most successful films exhibited in 3 The Incredibles 2 Hotel Transylvania 3: Summer Vacation Mamma Mia! Here We Go Again Mission: Impossible - Fallout The Nun

-office revenues decreased by 1.5% in 3Q18, compared with 0.5% yoy growth for the market as a whole, however the comparison should be adjusted to reflect the fact that the market has expanded by 7 screens yoy whereas NOS had 3 fewer screens in operation in 3Q18 in comparison with 3Q17, essentially due to ongoing refurbishment work in one of its multiplexes (at Oeiras Parque shopping centre). NOS continues to maintain its leading market position, with a market share of 62.4% in terms of gross revenues in 3Q18.

In the Audiovisuals arena, NOS distributed 8 of the top 10 cinema box-office hits in 3 The Incredibles 2 Mamma Mia! Here We Go Again Mission: Impossible - Fallout The Nun Meg Skyscraper Ant-Man and the Wasp

Revenues

In 3Q18 Mobile Termination Rates (MTRs) were cut by 44% to 0.42 eurocents from the 0.75 eurocents rate that had been in place since 2H17. Revenue trends are therefore not directly comparable. Adjusting for the regulatory effect, core telco revenues grew by 1.8%, a similar pace of growth to the previous quarter. Unadjusted growth in telco revenues was 0.9%, reaching 376.2 million euros in 3Q18.

Consolidated revenues increased by 0.7% to 395 million euros (adjusted growth of 1.7%) up from 0.5% growth in the previous quarter, reflecting a combination of the aforementioned increase in telco revenues and less negative trends in audiovisuals and cinema revenues which fell by 3.1%, compared with negative 17.7% in 2Q. The aforementioned impact of the MTR cuts in 3Q18 affects like for like comparision in revenues per segment. Adjusted revenues in the Consumer and the Business and Wholesale segments grew by 0.7% and 1% respectively supported by previously discussed solid operating trends and a less aggressive market environment.

The yoy decline in Audiovisuals and Cinema Revenues of 3.1% to 29 million euros is a marked improvement from negative 17.7% in 2Q18 and is in line with general market trends. The number of blockbuster movies exhibited and distributed and the volume of tickets sold was significantly better quarter on quarter, albeit still marginally weaker than the same quarter last year. Yoy comparisions in this division are still impacted by the renegotiation of the value of content contracts to Angola at the end of 2017 due to the challenging macroeconomic environment as explained in previous earnings reports. The value of the contract revision was partially offset by a similar reduction in the cost of the content distributed.

OPEX

Total OPEX fell 1% in 3Q18 to 238.8 million euros, reflecting an increased pace of yoy decline from 0.6% in 2Q18. Excluding direct costs, OPEX fell by 3.2% yoy to 106.2 million euros demonstrating primarily continued cost discipline and general operating efficiency. Direct costs also benefitted from the aforementioned MTR cut to 0.42 eurocents. As NOS is a net payer of termination rates to other operators, given relative market shares in mobile, reductions in MTRs drive a marginally greater reduction in costs than revenues. Adjusted for MTRs, Direct costs grew by 3.3% due to increased operating activity driving greater traffic related costs. In 3Q18 service costs associated with large corporate accounts were reclassified to Direct Costs from Operating and Structure Costs as they are directly related to the operating activity of this business segment. Both cost aggregates were restated from 1Q17 onwards enabling like-for-like comparability between periods.

As discussed in the operating review, work is underway within the context of our long term transformational project targeting opportunities to become a more agile and efficient operation, aiming to simplify and digitalize processes wherever possible, as a means of increasing customer satisfaction and ultimately reduce costs. The main addressable aggregates are commercial and other operating and structure costs, in addition to some potential opportunities for savings in customer related investments. The programme is still at an early stage of development and such financial impacts are relatively small the value captured from transformation initiatives will build up primarily from 2020 onwards, as the majority of projects move to implementation phase.

Table 4.
EBITDA and Operating Costs (YoY Change)	1Q17	2Q17	3Q17	4Q17	2017	1Q18	2Q18	3Q18

EBITDA	2.9%	5.5%	4.5%	4.1%	4.3%	3.0%	2.1%	3.5%
Operating Costs Excluding D&A	2.5%	3.3%	2.3%	1.6%	2.4%	(0.7%)	(0.6%)	(1.0%)

Operating and Structure Costs	4.8%	(14.8%)	6.9%	(7.0%)	(2.9%)	(7.2%)	(3.0%)	(1.8%)

Core Telco EBITDA increased 4.7% yoy to 144.6 million euros, driving a 1.4 pp increase in margin to 38.4% in 3Q18 and driving an increase in consolidated EBITDA to 156.2 million euros. As in previous quarters, the anticipated slowdown in telco revenue growth is successfully being compensated by improved operating efficiency, a trend that is set to continue with the acceleration of the transformation programme. The yoy decline in Audiovisuals and Cinema EBITDA reduced to negative 9.4% in 3Q18 from negative 18.7% in 2Q18, as a result of the sequential improvement in sector trends. Cinema and Audiovisuals EBITDA in 3Q18 amounted to 11.6 millon euros representing a 40% margin as a percentage of revenues.

Depreciation and Amortization was down by 8.8% yoy at 95.2 million euros and close to the levels of 2Q18, explained primarily by the lower yoy impact from impairment of existing mobile network equipment within the context of the major mobile upgrade project being deployed.

Consolidated Net income grew 34.1% to 44.1 million euros led by the growth in EBIT. Total Net financial expenses declined to 5.2 million euros compared with 6.5 million euros in 3Q17 and 7.9 million euros in 2Q18, benefitting from lower average cost of debt and lower charges from financing related commissions. Share of Results of Associates and Joint Ventures in 3Q18 continued to post a positive sequential trend quarter on quarter albeit the contribution was lower yoy amounting to 1.3 million euros given the weaker currency environment in Angola when compared with 2017.

(1) CAPEX = Increase in Tangible and Intangible Fixed Assets

As guided, the major transformation investments in the network discussed above are reflected in the increase in technical CAPEX, up by 7.3% yoy to 50.6 million euros, representing 13.4% of telco revenues in the quarter. Of total technical CAPEX in 3Q18 of 50.6 million euros, almost half was allocated to network expansion and substitution network upgrade in the quarter.

Customer related CAPEX within the telco business increased to 42.7 million euros in 3Q18 (11.4% of revenues) boosted by additional commercial activity primarily in new coverage areas, as is to be expected with the ramp up in expansion during the latter half of the year. This increased commercial activity is visible in the pick up in fixed access subscriber growth discussed in the operating review.

Total CAPEX was 101 million euros in 3Q18, 25.6% as a proportion of revenues, impacted primarily by the telco investments discussed above and the improvement in the Audiovisuals and Cinemas operation leading to higher investment in movie rights.

FCF before dividends recorded a significant increase yoy to 88.2 million euros in 3Q18 compared with 33.9 million euros in 3Q17, explained in part by a non-recurrent inflow, related with receival of a legal settlement, in favour of NOS, regarding a pending regulatory dispute over operator termination rate charges which had already been accounted for in the income statement in 1Q18. Although EBITDA grew by 3.5% yoy in 3Q18, it did not compensate the significant increase in CAPEX leading to a decline in EBITDA-CAPEX to 55.2 million euros. Working capital and non cash item adjustments in EBITDA-CAPEX were positive due primarily to the positive contribution of trade balances payments with ZAP during the quarter and outstanding operator balances related with the aforementioned pending legal dispute. As such, Operating Cash Flow increased by 24.2% to 69.6 million euros. Of the remaining cash items, interest paid was significantly lower compared with 3Q17 and also 18.6% lower then the previous quarter explained mostly by the continued decline in average cost of debt. The non-recurrent Cash Movements is explained by interest received from the outstanding legal settlement.
