Operational and Financial Results

Monterrey, Mexico, April 17, 2018— Mexican airport operator Grupo Aeroportuario del Centro Norte, S.A.B. de C.V., known as OMA (NASDAQ: OMAB; BMV: OMA), today reported its unaudited, consolidated results for the first quarter of 2018.1

International passenger traffic increased 5.8%, and ten airports recorded increases in international traffic. Monterrey (+8.7%; +24,454 passengers) had the largest increase, principally as a result of higher traffic on the Atlanta and Detroit routes.

See Annex Table 1 for more detail on passenger traffic by airport.

Air cargo volumes decreased 0.9%. Of total air cargo volume, 61.7% was domestic and 38.3% was international.


Commercial Operations

OMA implements our commercial strategy through continuous improvement in the services offerings in our airports. This strategy resulted in the opening of 10 commercial initiatives in 1Q18, including car rental, hotel promotion, advertising, and banking services. The occupancy rate for commercial space in the terminal buildings was 98.1% in 1Q18.




Hotel Services

§The NH Collection Terminal 2 Hotel had an 85.7% occupancy rate, compared to 84.3% in 1Q17. The average room rate was Ps. 2,342 per night. Revenues increased 0.5% to Ps. 65 million.
§The Hilton Garden Inn had a 78.5% occupancy rate, up 2.5 percentage points compared to 1Q17, with an average room rate of Ps. 2,053. Revenues increased 0.3% to Ps. 24 million.

OMA Carga Operations

§OMA Carga increased both air and land freight logistics activities, recording a 13.3% increase in revenues to Ps. 39 million. Freight handled grew 25.7% to 9,895 metric tons.

Industrial Services

§OMA VYNMSA Aero Industrial Park: The three operating warehouses generated Ps. 5.6 million in revenues. In March 2018, a five-year lease was signed for a 10,500 m2 warehouse that will begin generating revenues in August 2018.


Consolidated Financial Results


Aeronautical revenues increased 18.7% to Ps. 1,204 million, principally as a result of higher traffic volumes and increases in specific tariffs in January 2018. Revenue from domestic passenger charges increased 25.2%, revenue from international passenger charges increased 9.0%, and other aeronautical services revenue increased 11.0%.

Monterrey contributed 43.5% of aeronautical revenues, Culiacán 11.0%, Chihuahua 6.4%, and Ciudad Juárez 5.5%.

Aeronautical revenues per passenger were Ps. 245.6, an increase of 9.9%.

Non-aeronautical revenues increased 11.3% to Ps. 376 million and represented 23.8% of the sum of aeronautical and non-aeronautical revenues. The increase reflected principally the expansion of commercial activities.




Non-aeronautical revenues per passenger increased 3.0% to Ps. 76.7. Non-aeronautical revenues per passenger, excluding diversification activities, increased 6.2% to Ps. 48.6.





Commercial activities contributed an incremental Ps. 21 million (+13.8%). The line items with the largest increases were:

§Car rental (+59.1%; +Ps. 11 million), as a result of 21 new rental locations since 3Q17 and better contractual terms starting in 1Q18.
§Restaurants (+41.8%; Ps. +8 million), as a result of improvements in the commercial offering in the Monterrey airport starting in 3Q17, and the opening of five new establishments during 4Q17.
§Parking (+11.7%; +Ps. 5 million), as a result of increased capacity in the Monterrey airport and the growth in passenger traffic.

Diversification activities contributed an additional Ps. 8 million (+5.9%). The most important contribution came from OMA Carga (+13.3%; +Ps. 5 million).

Complementary activities generated an increase of Ps. 9 million (+17.0%).

Construction revenues, which represent the value of improvements to concessioned assets, were Ps. 352 million (+32.2%) during the quarter. They are equal to construction costs and generate neither a gain nor a loss. Construction revenues and costs are a function of the advance in execution of projects in the Master Development Programs (MDP) in the 13 airports, and variations depend on the rate of project execution. The increase in 1Q18 reflects the large number of MDP projects currently underway. (See Notes to the Financial Information and discussion of MDP expenditures below.)

Total revenues, including construction revenues, increased 19.4% to Ps. 1,932 million.

Costs and Operating Expenses

The total cost of airport services and general and administrative expenses (G&A), excluding those related to the hotels and industrial park, increased 1.7%. The largest variation was in minor maintenance, which decreased principally because of the calendar for work scheduled during the year.




The major maintenance provision decreased 6.8% to Ps. 46 million. The balance of the maintenance provision as of March 31, 2018 was Ps. 885 million, compared to Ps. 858 million at the end of 2017.

The airport concession tax increased 15.8% as a result of the growth in revenues.

The technical assistance fee increased 21.1% to Ps. 39 million. See the Notes to the Financial Information for the calculation base.

As a result of the foregoing, total operating costs and expenses increased 13.7% to Ps. 987 million, principally as a result of the increase in construction costs. Excluding construction costs, total costs and operating expenses were Ps. 635 million, an increase of 5.5%.





Adjusted EBITDA and Operating Income

Adjusted EBITDA increased 23.1% to Ps. 1,072 million, as a result of OMA’s continuing initiatives to increase revenues and control costs and expenses. The Adjusted EBITDA margin was 67.9%, the highest quarterly margin in OMA’s history. (See Notes to the Financial Information for additional discussion of Adjusted EBITDA.)

Operating income rose 25.9% to Ps. 945 million, with an operating margin of 48.9%.


Financing Expense

Financing Expense decreased 37.1% to Ps. 91 million, principally because of a smaller exchange loss.






Taxes were Ps. 244 million. The effective tax rate was 28.5%.

Net Income

Consolidated net income increased 44.0% to Ps. 610 million.

Earnings per share, based on net income of the controlling interest, increased 44.7% to Ps. 1.55; earnings per ADS increased 50.6% to US$0.67. Each ADS represents eight Series B shares.

MDP and Strategic Investments

Total capital expenditures and major maintenance included in the MDP and strategic investments3 were Ps. 423 million and included Ps. 352 million in improvements to concessioned assets, Ps. 25 million for major maintenance, and Ps. 46 million for strategic investments.



3 The amounts for MDP and strategic investments include works, services, and paid and unpaid acquisitions; the latter are included in accounts payable for the period.





The most important projects in 1Q18 were:


As of March 31, 2018, total debt was Ps. 4,612 million and net debt was Ps. 1,946 million. The ratio of net debt to Adjusted EBITDA was 0.48 times. Of total debt, 97% was denominated in Mexican pesos, and 3% in U.S. dollars.





Derivative Financial Instruments

As of the date of this report, OMA has no derivatives exposure.


Cash Flow Statement

For the first three months of 2018, operating activities generated cash of Ps. 843 million, a 25.8% increase compared to the same period of 2017. The increase resulted principally from higher operating income, an increase in accounts payable to related parties, and increases in provisions for taxes and other expenses, which were partially offset by an increase in client accounts receivable.

Investing activities used cash of Ps. 312 million, principally for Ps. 335 million in improvements to concessioned assets and Ps. 40 million for property, plant and equipment.

Financing activities generated an outflow of Ps. 67 million, principally for interest payments.

As a result of the foregoing, cash increased Ps. 464 million compared to December 31, 2017. The balance of cash and cash equivalents was Ps. 2,666 million as of March 31, 2018.

Notes to the Financial Information

Financial statements are prepared in accordance with International Financial Reporting Standards (“IFRS”), and presented in accordance with IAS 34 “Interim Financial Reporting.”

Adjusted EBITDA: OMA defines Adjusted EBITDA as EBITDA less construction revenue plus construction expense and maintenance provision. Construction revenue and construction cost do not affect cash flow generation and the maintenance provision corresponds to capital investments. Adjusted EBITDA should be not considered as an alternative to net income, as an indicator of our operating performance, or as an alternative to cash flow as an indicator of liquidity, or as an alternative to EBITDA.

Adjusted EBITDA margin: OMA calculates this margin as Adjusted EBITDA divided by the sum of aeronautical revenue and non-aeronautical revenue.

Aeronautical revenues: are revenues from rate-regulated services. These include revenue from airport services, regulated leases, and access fees from third parties to provide complementary and ground transportation services. Airport service revenues include principally departing domestic and international passenger charges (TUA), landing fees, aircraft parking charges, passenger and carry-on baggage screening, and use of passenger jetways, among others. Revenue from third party access fees to provide complementary services include revenue sharing for ramp services, aircraft towing, water loading and unloading, cabin cleaning, electricity supply, catering, security, and aircraft maintenance, among others. Revenues from regulated leases include principally rental to airlines of office space, hangars, and check-in and ticket sales counters. Revenues from access charges for providers of ground transportation services include charges for taxis and buses.

Airport Concession Tax (DUAC): This tax, the Derecho de Uso de Activos Concesionados, is equal to 5% of gross revenues, in accordance with the Federal Royalties Law.

American Depositary Shares (ADS): Securities issued by a U.S. depositary institution representing ownership interests in the deposited securities of non-U.S. companies. Each OMA ADS represents eight Series B shares.

Capital expenditures, Capex: includes investments in fixed assets (including investments in land, machinery, and equipment) and improvements to concessioned properties.

Cargo unit: equivalent to 100 kg of cargo.

Checked Baggage Screening: During 2012, OMA began to operate checked baggage screening in its 13 airports in order to increase airport security and in compliance with the requirements of the Civil Aviation General Directorate (DGAC). This screening uses the latest technology and is designed to detect explosives in checked baggage. The cost of maintenance of the screening equipment is considered a regulated activity and will be recovered through the maximum rates, while the operational aspects are assessed as a non-regulated service charge. In accordance with the Civil Aviation Law and the regulations issued by the DGAC, the primary responsibility for damages and losses resulting from checked baggage lies with the airline. Notwithstanding the foregoing, OMA may be found jointly liable with the airline through a legal proceeding if and when all of the following elements are proven: a) occurrence of an illegal act, b) caused by the willful misconduct or bad faith of our subsidiary OMA Servicios Complementarios del Centro Norte, S.A. de C.V., and c) related to or occurring during the baggage screening undertaken by OMA Servicios Complementarios del Centro Norte, S.A. de C.V.




Construction revenue, construction cost: IFRIC 12 “Service Concession Arrangements” addresses how service concession operators should apply existing International Financial Reporting Standards (IFRSs) to account for the obligations they undertake and rights they receive in service concession arrangements. The concession contracts for each of OMA’s airport subsidiaries establishes that the concessionaire is obligated to carry out construction or improvements to the infrastructure transferred in exchange for the rights over the concession granted by the Federal Government. The latter will receive all the assets at the end of the concession period. As a result the concessionaire should recognize, using the percentage of completion method, the revenues and costs associated with the improvements to the concessioned assets. The amount of the revenues and costs so recognized should be the price that the concessionaire pays or would pay in an arm’s length transaction for the execution of the works or the purchase of machinery and equipment, with no profit recognized for the construction or improvement. The change does not affect operating income, net income, or EBITDA, but does affect calculations of margins based on total revenues.

Earnings per share and ADS: use the weighted average of shares or ADS outstanding for each period, excluding Treasury shares from the operation of the share purchase program.

EBITDA: For the purposes of this report, OMA defines EBITDA as net income minus net comprehensive financing income, taxes, and depreciation and amortization. EBITDA should be not considered as an alternative to net income, as an indicator of our operating performance, or as an alternative to cash flow as an indicator of liquidity. Our management believes that EBITDA provides a useful measure of our performance that is widely used by investors and analysts to evaluate our performance and compare it with other companies. However, it should be noted that EBITDA is not defined under IFRS, and may be calculated differently by different companies.

Employee Benefits: IFRS 19 (modified) “Employee Benefits” requires that cumulative actuarial gains and losses from pension obligations be recognized immediately in comprehensive income. These gains and losses arise from the actuarial estimates used for calculating pension liabilities as of the date of the financial statements.

Hilton Garden Inn: The Hilton Garden Inn in the Monterrey International Airport.

IAS 34 “Interim Financial Reporting”: This norm establishes the minimum content that interim financial statements should include, as well as the criteria for the formulation of the financial statements.

International Financial Reporting Standards (IFRS): Financial statements and other information are presented in accordance with IFRS and their Interpretations. The financial statements for the year ended December 31, 2010 were the last statements prepared in accordance with Mexican Financial Reporting Standards.

Major Maintenance Provision: represents the obligation for future disbursements resulting from wear and tear or deterioration of the concessioned assets used in operations including: runways, platforms, taxiways, and terminal buildings. The provision is increased periodically for the wear and tear to the concessioned assets and the Company’s estimates of the disbursements it needs to make. The use of the provision corresponds to the outflows made for the conservation of these operational assets.

Master Development Plan (MDP): The investment plan agreed to with the government every five years, under the terms of the concession agreement. These include capital investments and maintenance for aeronautical activities, and exclude commercial and other non-aeronautical investments. The investment horizon is 15 years, of which the next five years are committed investments.

Maximum Rate System: The Ministry of Communications and Transportation (SCT) regulates all our aeronautical revenues under a maximum rate system, which establishes the maximum amount of revenues per workload unit




(one terminal passenger or 100kg of cargo) that may be earned by each airport each year from all regulated revenue sources. The concessionaire sets and registers the specific prices for services subject to regulation, which may be adjusted every nine months as long as the combined revenue from regulated services per workload unit at an airport does not exceed the maximum rate. The SCT reviews compliance with maximum rates on an annual basis after the close of each year.

NH Collection T2 hotel: The NH Collection hotel in Terminal 2 of the Mexico City International Airport.

Non-aeronautical revenues: are revenues that are not subject to rate regulation. These include revenues derived from commercial activities such as parking, advertising, car rentals, leasing of commercial space, freight management and handling, and other lease income, among others; diversification activities, such as the Hotel NH Terminal 2; and complementary activities, such as checked baggage screening.

Passengers: all references to passenger traffic volumes are to terminal passengers.

Passengers that pay passenger charges (TUA): Departing passengers, excluding connecting passengers, diplomats, and infants.

Passenger charges (TUA, Tarifa de Uso de Aeropuerto): are paid by departing passengers (excluding connecting passengers, diplomats, and infants). Rates are established for each airport and are different for domestic and international travel.

Prior period comparisons: unless stated otherwise, all comparisons of operating or financial results are made with respect to the comparable prior year period. Balance sheet numbers are compared to the balances at the end of the prior year.

Strategic investments: refers only to those investments that are additional to those in the Master Development Plan.

Technical Assistance Fee: Until June 13, 2015, this fee was charged as the higher of US$3.0 million per year or 5% of EBITDA before technical assistance. With the signing of an Amendment to the Technical Assistance and Technology Transfer Agreement effective June 14, 2015, the annual fee is charged as the higher of US$ 3.0 million per year or 4% of EBITDA for the first three years and 3% for the final two years of the agreement. For the purposes of this calculation, consolidated EBITDA before technical assistance takes into account only the subsidiaries holding the airport concessions or that provide personnel services directly or indirectly to the airports.

Terminal passengers: includes passengers on the three types of aviation (commercial, charter, and general aviation), and excludes passengers in transit.

Unaudited financials: financial statements are unaudited statements for the periods covered by the report.

Workload Unit: one terminal passenger or one cargo unit.
