Filing Type: Form 6-K (Report of Foreign Private Issuer)
Reporting Period: Fourth Quarter and Full Year ended December 31, 2019

Key Financial Metrics (4Q19)

Material Changes vs. Prior Period

• Revenue Growth: Consolidated revenue increased 15.8% YoY, driven by a 120.9% surge in construction revenues (primarily in Mexico) and an 8.4% increase in aeronautical services. Excluding construction revenues, organic revenue growth was 6.3%.
• Profitability Decline: Net Income and EBITDA declined YoY. EBITDA dropped 1.0% to Ps. 2,436.4 million. This decline is largely attributed to the absence of a Ps. 134.6 million non-recurring insurance recovery in 4Q18 related to Hurricane Maria. Excluding this one-time item, EBITDA would have increased 4.8%.
• Cost Increases: Operating costs rose 32.3% YoY, including construction costs. Excluding construction, costs rose 22.2%, driven by higher maintenance, professional fees, and a change in amortization methodology in Colombia (switching from percentage of completion to straight-line).
• Passenger Traffic: Total traffic increased 7.1% YoY to 14.0 million passengers. Growth was led by Puerto Rico (+18.1%), Colombia (+9.4%), and Mexico (+3.6%).
• Commercial Revenue per Passenger: Declined 3.4% to Ps. 92.3, with significant drops in Puerto Rico (-13.9%) and Mexico (-2.5%), offset by growth in Colombia (+16.6%).

Outlook, Risks, and Management Commentary

• Capital Investment: ASUR significantly increased Capex to Ps. 1,728.0 million in 4Q19, primarily to modernize Mexican airports under the Master Development Plan. This heavy investment impacted cash flow from investing activities.
• Debt Reduction: The company strengthened its balance sheet, reducing Net Debt to LTM EBITDA to 0.7x and improving the Interest Coverage Ratio to 10.8x.
• Accounting Impacts: Results were affected by IFRIC 12 interpretations regarding construction revenues and costs, as well as a change in depreciation methodology in Colombia. These non-cash items impacted reported margins but not necessarily cash generation.
• Foreign Exchange: The company reported a Ps. 139.5 million foreign exchange loss in 4Q19 due to the appreciation of the Mexican peso against the U.S. dollar, contrasting with a gain in the prior year.
• Guidance: The filing does not contain specific forward-looking financial guidance for 2020, though it references ongoing modernization plans and tariff regulations in Mexico and Colombia.

Investor Verification Checklist

• Adjusted EBITDA: Verify the "Adjusted EBITDA" figure (excluding the 4Q18 Hurricane Maria insurance recovery) to assess true operational performance trends.
• Construction Revenue Quality: Analyze the sustainability of the 120.9% revenue growth driven by construction services, noting that these are often non-recurring or project-based.
• Commercial Yield: Investigate the reasons behind the decline in commercial revenue per passenger in Mexico and Puerto Rico despite traffic growth.
• Colombia Amortization: Confirm the long-term impact of the change in amortization methodology in Colombia on future depreciation and amortization expenses.
• Currency Exposure: Monitor the impact of Mexican peso volatility on financial results, given the significant U.S. dollar-denominated debt in Puerto Rico.
