Core Thesis - Grupo Aeroportuario del Sureste, S. A. B. de C. V. (ASR) is viewed positively due to its strong fundamentals, growth potential, and attractive valuation compared to its current share price of $319.48 as of October 8th [1][4]. Company Overview - ASR operates a portfolio of airports primarily in Mexico, Puerto Rico, and Colombia, and has recently expanded into U.S. airport retail through the acquisition of URW Airports, LLC [2]. - The company owns Cancun International Airport, along with significant stakes in San Juan International and Medellín airports [2]. Financial Performance - ASR has delivered over 21 times price return since 2000, with operating margins above 50%, ROIC of 21%, ROE of 29%, and ROA of 15% [3]. - The company maintains a strong balance sheet with low debt levels despite ongoing expansion efforts at Cancun International [3]. Valuation and Growth Potential - Current valuation metrics include a forward P/E of 13x and a free cash flow multiple of 19x, indicating an attractive investment opportunity [3]. - A conservative DCF analysis suggests a fair value of $468 per share, representing nearly 50% upside from the current price, with potential to exceed $600 under optimistic scenarios [4]. Competitive Advantages - ASR benefits from a substantial competitive moat, as airports are difficult to replicate and face limited competition from alternative travel modes [3]. - The company’s international customer base at key airports provides insulation from domestic economic volatility [4]. Market Context - The bullish thesis on ASR aligns with previous positive coverage of Grupo Aeroportuario del Centro Norte, S.A.B. de C.V. (OMAB), which also highlighted strong passenger growth and high operating margins [5].
