We continue to believe that profitability improvements derived from more efficient terminals, along with an enhanced operating leverage are already priced in. Still, OMA should continue to benefit from healthy traffic readings, which together with higher maximum tariffs should bring further profitability growth. Our thesis considers the following: FCF should be under pressure in 2016 and 2017. Higher CAPEX commitments should reduce the company s ability to turn EBITDA into FCF. Waiting for more appealing valuations to participate on the name. Higher traffic should allow OMA to continue to improve its profitability, as operating leverage kicks in. Monterrey remains the third most important hub in Mexico. After the saturation of the Mexico City airport, domestic carriers are developing secondary bases in Monterrey, further boosting traffic growth. Business diversification to reduce results volatility. OMA s diversification activities should allow the company to reduce its exposure to aeronautical traffic. 2Q16 Highlights Traffic rose 8.7% YOY, driven by Culiacan (+16.7% YOY), Ciudad Juarez (+32.7% YOY) and Monterrey (+5.5% YOY). Aero revenue per PAX increased 16.8% YOY, as OMA continues to implement its new maximum tariffs. Non-aero revenues per PAX jumped 14.5% YOY, as the company faces easy comps from the opening of Monterrey s hotel. OMA s operating margin expanded 650bps to 51.1%, while its EBITDA margin did so by 480 bps to 62.5%. OMA generated P$431 million in FCF, despite a P$107 million CAPEX investment, due to strong operating performance. EV/EBITDA FWD 12M PRICE PERFORMANCE VS.

Investment Thesis OMA is the cheapest airport operator among our Mexican sample; still, valuations are not attractive. OMA is currently trading at roughly 15x 12M FWD EV/EBITDA, versus its 3-year average of around 11x. Moreover, when adjusting its 2016e ROE of 25.8% for its P/BV, it remained practically unchanged from a year ago (3.8%), leading us to believe that all the benefits for the year are already priced in. FCF should be under pressure in 2016 and 2017. Although we believe that OMA s margins should expand, aided by operating leverage, higher CAPEX commitments should reduce the company s ability to turn EBITDA into FCF. As a result, 2016 and 2017 FCF yield should land at 1.3 and 1.9%, respectively, at current prices. Waiting for more appealing valuations to participate on the name. Higher traffic should allow OMA to keep improving its profitability, mainly through its Monterrey airport, as it represents one of Mexico s largest hubs. As such, we believe OMA s traffic should post a 2015-2020 CAGR of 6.3%, on the back of Monterrey s CAGR of 6.4%. Monterrey remains the third most important hub in Mexico. After the saturation of the Mexico City airport, domestic carriers are developing secondary bases in Monterrey, including AEROMEX, Volaris, and Interjet, the market s largest players, while VivaAerobus a growing low cost carrier established its main base at that airport. Business diversification to reduce results volatility. We applaud OMA s efforts to reduce its dependence on aeronautical traffic through the investments made in two hotels and an industrial park. However, in terms of revenues, these businesses will only contribute with between 6 and 7% of revenues by 2020. We are maintaining our price target of P$108.8 for the next 12 months, while introducing a Market Underperformer rating after the rally witnessed in the last month.

2Q16 Main Highlights OMA s PAX traffic keeps slowing down, as it faces an increasingly tougher comp base after linking 16 months of double-digit growth up to last December. As such, traffic rose 8.7% YOY, mainly driven by an 10.4% expansion on the domestic front. Delving in, Monterrey (+5.5% YOY), Culiacan (+16.7% YOY) and Ciudad Juarez (+32.7% YOY) remained as the main contributors. Revenue excluding construction rose 26.4% YOY driven by new maximum tariffs. We should recall that after OMA concluded its new MDP negotiation by the end of last year, it began to gradually implement its newly approved tariffs during the quarter, starting with the service portion in April and passenger charges in May. Aero revenue per PAX rose 16.8% YOY, reflecting the partial implementation of OMA s new maximum tariffs, which should reflect an increase of roughly 14% YOY when fully implemented. Non-aero revenue per PAX jumped 14.5% YOY, as the company enjoyed an easy comp base from the opening of Monterrey s hotel back in last year s third quarter, as well as the first revenues from its industrial park. Operating leverage allows for margin growth. During the quarter cost of services rose 17.6% YOY, or 8.1% per PAX as the company continues to benefit from the dilution of its fixed cost base among a larger passenger base, falling behind revenue per PAX growth. As such, OMA s operating and EBITDA margins rose 650 and 480bps, reaching 51.1 and 62.5%, respectively. OMA generated P$431 million in FCF, due to the company s solid operating performance, although partially offset by P$107 million in CAPEX. We should note that the company has a P$1.4 billion CAPEX commitment for 2016, which should translate into stronger CAPEX for the remainder of the year after having spent just P$148 million by 1H16. Thus, the company s net debt reached P$2.8 billion, equal to a 53.2 % QOQ decrease, due to the payment of a P$1.4 billion dividend, reaching 1.0x net debt/ebitda ratio. Guidance Update. OMA adjusted its guidance upwards, calling for traffic of between 8 and 10% for FY 2016, as well as an EBITDA margin of between 61 and 63%.

Investment Risks In addition to the risks related to macroeconomic aspects, we believe the most relevant risks in the Mexican Market are: 1) changes in government policy which might or might not affect the aeronautical industry; 2) unexpected changes in regulation by regulatory authorities such as: SCT, DGAC, etc. Some of the risks regarding OMA are: 1) limited operating flexibility given its condition as borrower of a public service regulated by the federal government, 2) possibility of losing the concession to the federal government under certain circumstances not controlled by the company; 3) relative dependence on the results of Monterrey s International Airport; 4) negative performance produced by terrorism and international conflicts as well as their consequences; 5) adverse impact of natural disasters on the company s activities; 6) strong dependence on airlines ability to operate; Stock Price Performance vs Analyst Estimates 120.0 115.0 110.0 105.0 100.0 95.0 90.0 11/07/2016 108.80 M arket Performer 25/07/2016 108.80 M arket Underformer 85.0 80.0 75.0 70.0 Jul-15 Aug-15 Sep-15 Sep-15 Oct-15 Nov-15 Nov-15 Dec-15 Jan-16 Jan-16 Feb-16 Mar-16 Apr-16 Apr-16 May-16 Jun-16 Jun-16 Jul-16 Aug-16 Price Price Target
