Executive Summary

This report provides a comprehensive analysis of Grupo Aeroportuario del Sureste, S.A.B. de C.V. (ASR), a multinational airport operator with a significant presence in Mexico, Puerto Rico, and Colombia. The analysis indicates that ASR represents a compelling case of an infrastructure operator at a strategic inflection point. The company’s core investment thesis is anchored in its world-class profitability, disciplined financial management, and a successful international diversification strategy that is increasingly serving as a crucial counterbalance to emerging challenges in its historically dominant Mexican market.

ASR’s financial profile is exceptionally robust, characterized by industry-leading EBITDA margins consistently near 70%, a strong cash generation capacity, and a conservative balance sheet that currently features a negative net debt position. This financial strength underpins a substantial shareholder return program, highlighted by a dividend yield that is among the highest in the sector. Management has demonstrated a strong track record of operational execution and strategic foresight, particularly through the timely acquisitions of airport concessions in Puerto Rico and Colombia. These international assets are now the primary drivers of consolidated passenger traffic growth, offsetting recent stagnation and declines in the company’s Mexican operations.

However, the investment landscape for ASR is not without significant risks that temper the bullish outlook. The company’s heavy reliance on its flagship Cancún International Airport, which contributes the majority of revenue, is facing its first direct competitive threat from the newly inaugurated Tulum International Airport. Concurrently, the broader Mexican regulatory environment has become less predictable, as evidenced by recent government actions and disputes with U.S. authorities, introducing a new layer of political risk to the long-term concession model. Furthermore, ASR’s performance remains highly sensitive to macroeconomic cycles in the United States, fluctuations in the MXN/USD exchange rate, and the inherent volatilities of the global tourism industry.

Ultimately, the central consideration for an investor is weighing the proven growth and profitability of the Colombian and Puerto Rican assets against the heightened competitive and regulatory pressures facing the core Mexican portfolio. The company’s current valuation appears to reflect this dichotomy, trading at a discount to its domestic peers. The key determination is whether this discount and the substantial dividend yield offer adequate compensation for the evolving risks, or if the challenges in the Mexican market will overshadow the positive momentum from the international segments and the returns from its ambitious capital expenditure program.

Company Overview & Business Model

Grupo Aeroportuario del Sureste has evolved from a regionally focused Mexican airport concessionaire into a diversified, multinational infrastructure operator. Its business model is built upon long-term concessions that grant it the right to operate, maintain, and develop a portfolio of strategically located airports, generating revenue from both regulated aeronautical activities and unregulated, high-margin commercial services.

Airport Portfolio: A Diversified Tricontinental Network

ASR operates a portfolio of 16 airports across three countries: Mexico, Puerto Rico, and Colombia.1 This geographic diversification is the result of a deliberate strategy to expand beyond its original mandate and mitigate country-specific risks.2

  • Mexico: The foundation of ASR’s portfolio consists of nine airports in the southeastern region of Mexico, granted as a concession package during the country’s airport privatization in 1998.2 This group includes Cancún International Airport (CUN), Cozumel International Airport (CZM), Mérida International Airport (MID), Huatulco International Airport (HUX), Oaxaca International Airport (OAX), Veracruz International Airport (VER), Villahermosa International Airport (VSA), Tapachula International Airport (TAP), and Minatitlán International Airport (MTT).3 Cancún (CUN) is the undisputed cornerstone of the entire company, serving as one of the world’s premier international tourist gateways and accounting for approximately 59% of ASR’s total revenue.4 Its performance is intrinsically linked to the health of tourism in the Yucatán Peninsula’s “Mayan Riviera”.4
  • Puerto Rico: In 2013, ASR marked its first major international expansion by acquiring a controlling stake (currently 60%) in Aerostar Airport Holdings, the concessionaire for the Luis Muñoz Marín International Airport (SJU) in San Juan.1 SJU is a critical hub for air traffic in the Caribbean, providing ASR with a foothold in a U.S. dollar-denominated market and a different set of economic and tourism drivers.2
  • Colombia: ASR solidified its presence in South America in 2017 with the acquisition of a controlling stake (now nearly 100%) in Airplan, the concessionaire for six airports in Colombia.1 This portfolio includes the José María Córdova International Airport (MDE), which serves Medellín, Colombia’s second-largest city, as well as five other regional airports: Olaya Herrera (EOH), Los Garzones (MTR), El Caraño (UIB), Antonio Roldán Betancourt (APO), and Las Brujas (CZU).2 This move tapped into the rapidly growing Colombian tourism and business travel markets.

The strategic rationale behind this international expansion has become increasingly apparent in recent operational results. As passenger traffic in the mature Mexican market has shown signs of slowing, the Colombian and Puerto Rican segments have delivered robust, often double-digit, growth, providing a critical engine for the company’s consolidated performance.5 This successful diversification has transformed ASR from a pure-play on Mexican tourism into a more resilient, geographically balanced Latin American airport operator, where the international assets now function as a significant hedge against weakness in the core Mexican market.

Revenue Streams: A Dual-Engine Model

ASR’s business model is structured around two distinct but complementary revenue streams: regulated aeronautical services and unregulated non-aeronautical (or commercial) services.4 This dual structure provides a stable, predictable base of regulated income while offering significant upside potential from high-margin commercial activities. Based on fourth-quarter 2024 results, aeronautical revenues accounted for approximately 66.4% of the total, with non-aeronautical revenues comprising the remaining 33.6%.8

  • Aeronautical Revenues: These revenues are generated directly from the use of airport infrastructure by airlines and passengers and are subject to government regulation. The largest single component is the passenger departure fee (known as TUA in Mexico), which is collected by airlines as part of the ticket price and remitted to ASR. This fee alone accounts for roughly 35% of the company’s total revenue.4 Other aeronautical revenues include fees for aircraft landing and parking, charges for use of passenger boarding bridges, and airport security fees.4
  • Non-Aeronautical Revenues: This segment represents a key area of strategic focus and growth for ASR, as these revenues are not subject to government price caps. They are primarily derived from leasing commercial space within the airport terminals to a wide range of tenants, including duty-free and retail stores, restaurants and bars, car rental agencies, and financial service providers.4 ASR also collects access fees from third parties that provide complementary services at the airport, such as ground handling, catering, and baggage handling.8 The company has demonstrated considerable success in growing this segment, with commercial revenue per passenger showing a strong upward trend, increasing by 17.5% year-over-year in the first quarter of 2025 to Ps. 146.8.5

Regulatory Framework & Concession Structure

ASR’s operations in Mexico are governed by a long-term concession model established during the privatization of the country’s airport system in the late 1990s. This framework is designed to provide stability and encourage private investment in critical infrastructure.

The company was granted 50-year concessions to operate, maintain, and develop its nine Mexican airports, beginning in 1998. These concessions can be extended for an additional period of up to 50 years, providing a very long-term horizon for operations and investment planning.2

The primary regulatory body is Mexico’s Ministry of Infrastructure, Communications, and Transportation (SCT), which is responsible for enforcing the Mexican Airport Law and overseeing the concession agreements.10 Under the terms of the concessions, ASR is obligated to provide continuous and non-discriminatory airport services, maintain the facilities in good working order, and pay a concession fee to the government, which is calculated as a percentage of aeronautical and non-aeronautical revenues.4

A central feature of the regulatory system is the Master Development Plan (MDP). Every five years, ASR must submit a comprehensive 15-year plan to the SCT for approval. This plan includes binding capital investment commitments for the next five years and sets the “maximum tariff” per workload unit that ASR can charge for its regulated aeronautical services.9 This mechanism creates a predictable, albeit somewhat rigid, operating environment where revenue potential is directly linked to committed capital expenditures.

Industry Dynamics & Market Position

ASR operates within a largely stable and structured industry in Mexico, characterized by high barriers to entry and a rational competitive landscape. However, recent shifts in the regulatory environment and evolving travel patterns are introducing new dynamics that could impact all major operators.

Mexican Airport Industry Structure: A Stable Oligopoly

The privatization of Mexico’s airports in the late 1990s created a durable oligopoly comprised of three publicly traded groups, each with a distinct geographic focus.2 This structure, fortified by long-term, exclusive government concessions, creates exceptionally high barriers to entry, effectively granting the incumbents a powerful competitive moat against new private-sector entrants.4 Competition primarily arises from government-sponsored projects, such as the new airport in Tulum, or from other tourist destinations.9

  • Grupo Aeroportuario del Sureste (ASR): Dominates the southeastern region, with a portfolio heavily weighted towards international leisure travel, anchored by the Cancún airport.4
  • Grupo Aeroportuario del Pacífico (GAP): Operates 12 airports in Mexico’s Pacific and central regions, including major tourist destinations like Los Cabos (SJD) and Puerto Vallarta (PVR), alongside the major business hub of Guadalajara (GDL).13 Its traffic is a balanced mix of leisure and business.
  • Grupo Aeroportuario del Centro Norte (OMA): Manages 13 airports in Mexico’s central and northern industrial heartland. Its largest airport, Monterrey (MTY), serves as a key hub for business, manufacturing, and cargo traffic, making OMA more exposed to industrial and trade-related travel trends.15

Comparative Market Position

While all three groups operate under a similar concession model, their scale, profitability, and strategic focus differ.

In terms of passenger volume within Mexico, GAP is the largest operator, having handled 30.9 million passengers in the first half of 2024, followed by ASR with 21.7 million and OMA with 12.4 million.17 Financially, however, ASR often exhibits superior profitability. For instance, in the first quarter of 2025, ASR generated the highest net income of the three groups (Ps. 3.64 billion) despite GAP reporting higher total revenues, a testament to ASR’s strong margin profile.18 In terms of market capitalization, GAP is the largest at approximately $11.5 billion, followed by ASR at ~$9.5 billion and OMA at ~$5.5 billion.19 From a balance sheet perspective, ASR stands out with its negative net debt position, while OMA also maintains a conservative leverage profile. This contrasts with GAP, which operates with a higher level of debt.5

Industry Growth Drivers and Headwinds

The long-term outlook for the Mexican aviation sector is supported by powerful secular trends, though it is currently facing notable near-term headwinds.

Long-Term Drivers:

  • Tourism Growth: Mexico remains a premier global tourist destination. The post-pandemic travel rebound has been exceptionally strong, with international arrivals in the first five months of 2025 surging 14.2% year-over-year to 39.4 million. Crucially, tourism revenue during this period was 44.4% higher than in the same period of pre-pandemic 2019, indicating higher spending per visitor.26 The United States and Canada continue to be the dominant source markets, providing a stable base of demand.27
  • Nearshoring and USMCA: The trend of companies relocating manufacturing and supply chains from Asia to North America (“nearshoring”) is a significant tailwind for Mexico. This drives demand for business travel, air cargo, and logistics services, particularly benefiting airports in industrial regions operated by OMA and GAP.28
  • Favorable Demographics: A growing middle class within Mexico is expanding the addressable market for domestic air travel. The rise of low-cost carriers has made flying more accessible, and the country’s vast geography often makes air travel a more practical option than ground transport.30

Headwinds:

  • Regulatory Uncertainty: The stable and predictable regulatory framework, long a cornerstone of the investment thesis for Mexican airports, is facing a significant test. An ongoing dispute between the Mexican government and the U.S. Department of Transportation (DOT) regarding the 2015 U.S.-Mexico Air Transport Agreement has introduced a new level of political risk.31 The dispute centers on Mexico’s unilateral actions at the Mexico City airport (not operated by the private groups), including rescinding landing slots and forcing the relocation of cargo operations.33 These actions have been deemed anti-competitive by the U.S. DOT, which has retaliated by proposing the withdrawal of antitrust immunity for the Delta-Aeroméxico joint venture.34 While not directly impacting ASR, GAP, or OMA yet, this conflict sets a concerning precedent. It signals a shift toward a more interventionist government approach, raising the tail risk that the authorities could similarly seek to alter the terms of the private concessions, such as the crucial five-year tariff-setting process. Investors must now factor in a higher risk premium to account for this elevated political uncertainty.
  • Airline Industry Pressures: Airport operators are inextricably linked to the health of their airline customers. Global supply chain issues affecting aircraft deliveries and engine maintenance mandates, which recently grounded aircraft for Mexican carriers Volaris and VivaAerobus, can constrain capacity and limit passenger growth.18 An economic slowdown in key source markets could also pressure airline profitability and lead to route cuts.

Operational & Financial Performance Analysis

ASR has demonstrated a history of strong operational execution and robust financial results, characterized by a swift recovery from the COVID-19 pandemic, industry-leading profitability margins, and a resilient business model. However, a closer examination of recent trends reveals a significant divergence in performance across its geographic segments.

Historical Financial Performance

A review of ASR’s consolidated financial statements shows a strong growth trajectory, interrupted only by the pandemic in 2020. Total revenues, which stood at Ps. 16.8 billion in 2019, recovered and grew to Ps. 19.0 billion by 2023.9 Net income followed a similar path, surpassing its pre-pandemic level of Ps. 5.7 billion in 2019 to reach Ps. 10.7 billion in 2023.9

This momentum has carried into the current fiscal year. For the first quarter of 2025, ASR reported a strong 18.2% year-over-year increase in revenue to Ps. 8.8 billion. EBITDA grew by a healthy 11.7% to Ps. 5.7 billion, and net income rose 14.2% to Ps. 3.6 billion, underscoring the company’s continued ability to expand its bottom line.5

Analysis of Key Operational & Financial Metrics

  • Passenger Traffic: The most critical operational trend for ASR is the divergence in performance between its geographic segments. While total consolidated traffic for 2023 grew a healthy 10.0% to 43.5 million passengers, this figure masks underlying weakness in its core Mexican market.9 Throughout late 2024 and the first half of 2025, ASR’s monthly traffic reports have consistently shown flat to negative growth in Mexico, while the Puerto Rican and Colombian operations have posted strong, often double-digit, increases. For example, in April 2025, passenger traffic in Mexico grew by a mere 0.5%, whereas it surged by 13.5% in Puerto Rico and 4.8% in Colombia.5 This pattern continued into June 2025, with Mexico traffic declining 2.8% while Colombia grew 1.7%.38 This trend validates management’s diversification strategy and highlights the increasing importance of the international assets to ASR’s overall growth profile.
  • EBITDA Margins: ASR’s profitability is a key differentiating factor. The company consistently generates exceptionally high EBITDA margins, reflecting significant operating leverage and effective cost management. The Adjusted EBITDA margin for the first quarter of 2025 was 70.0%, following a margin of 69.7% in the fourth quarter of 2024.5 This level of profitability is a direct result of the Mexican concession model, which combines regulated, inflation-indexed aeronautical revenues with high-margin, unregulated commercial income. This structure provides a substantial cushion against operational headwinds, making ASR’s earnings more resilient to traffic volume fluctuations than a typical service company. This financial resilience is a cornerstone of the investment case, enabling the company to fund its extensive capital expenditure program and generous dividend simultaneously.
  • Return on Equity (ROE): ASR’s ability to generate returns for its shareholders is strong, with a trailing-twelve-month ROE reported at 25.76%.39 Historical data shows a robust recovery post-pandemic, with ROE at 22.7% in 2023 and 24.0% in 2022, a significant improvement from the low of 5.9% in 2020.20

Peer Benchmarking

When compared to its peers, ASR’s performance is impressive, particularly in terms of profitability.

  • International Peers: ASR’s EBITDA margin of approximately 70% is world-class. It stands significantly above that of major European operators like Aena, which reported a 58.8% EBITDA margin in 2023, and Fraport AG, which reported a margin of 30.1% for the same period.40 This stark difference highlights the highly profitable nature of the Mexican airport concession model compared to other regulatory regimes.
  • Domestic Peers: ASR’s profitability also appears to be at the top of its domestic class. While direct margin comparisons require standardized calculations, ASR’s ability to generate higher net income than GAP in the first quarter of 2025, despite having lower revenues, strongly suggests a superior margin structure.18 In terms of shareholder returns, ASR’s ROE of ~23-25% is robust but trails that of its domestic peers GAP (42.2%) and OMA (40.4%).20 This difference is likely attributable to ASR’s more conservative capital structure, which employs less financial leverage, and its larger total asset base.

Growth History & Future Opportunities

ASR’s growth strategy has evolved from managing a portfolio of regional Mexican airports to becoming a multinational operator. Its future growth hinges on the successful execution of a massive capital investment program, continued expansion of high-margin commercial revenues, and the sustained performance of its international assets.

Historical Growth Drivers: The International Pivot

The defining feature of ASR’s growth over the past decade has been its successful and strategically timed international expansion. The 2013 acquisition of a controlling interest in the concession for San Juan’s airport in Puerto Rico and the 2017 acquisition of the Airplan airport portfolio in Colombia were transformative events.2 These moves were not merely opportunistic but represented a clear strategic pivot to diversify revenue streams, reduce the company’s heavy reliance on the Mexican tourism market, and tap into new, high-growth regions in Latin America. This foresight is now paying significant dividends, as the strong performance of the Puerto Rican and Colombian segments is providing a crucial offset to the recent softness in the Mexican market, as consistently demonstrated in monthly traffic reports.5

Current Capital Expenditure Program: The Master Development Plan (MDP)

ASR is currently undertaking its most ambitious investment cycle to date under the Master Development Plan for 2024-2028. This plan, approved by Mexican authorities, commits the company to total capital expenditures of Ps. 29.6 billion (expressed in constant December 31, 2023 pesos) across its Mexican airports.9

The most striking feature of this program is its concentration. An overwhelming Ps. 22.3 billion, or approximately 75% of the total budget, is allocated to a single asset: Cancún International Airport.9 This massive investment is aimed at significantly expanding and modernizing the airport’s terminal buildings, commercial platforms, and access roads. The scale of this expenditure represents a high-stakes bet on the long-term growth and continued dominance of Cancún as the premier gateway to the Mayan Riviera. Other significant investments are planned for the airports in Mérida (Ps. 2.0 billion) and Oaxaca (Ps. 2.2 billion) to enhance their capacity and commercial offerings.9

This investment program is strategically necessary to maintain Cancún’s competitiveness, particularly in light of the new, government-backed international airport in nearby Tulum, which poses the first direct competitive threat to Cancún’s regional monopoly.9 However, the sheer size and concentration of the investment introduce considerable execution risk and place immense pressure on achieving adequate returns on invested capital. The success or failure of this Cancún expansion is arguably the single most critical variable for ASR’s long-term value creation.

Organic Growth Opportunities

Beyond the large-scale capacity expansions, ASR has several levers for organic growth:

  • Passenger Traffic: The fundamental driver of the business remains passenger volume. Future growth will depend on a combination of factors: a rebound in international tourism to Mexico, the continued strong performance of the Colombian and Puerto Rican markets, and the successful absorption of new capacity created by the MDP.
  • Commercial Revenues: There is significant runway to continue increasing non-aeronautical revenue per passenger. This is a key focus for management, as these revenues are unregulated and carry high margins. Growth can be achieved by optimizing the retail and dining mix in expanded terminal spaces, introducing new services, and leveraging technology to enhance the passenger experience. The 17.5% year-over-year growth in commercial revenue per passenger in the first quarter of 2025 is a clear indicator of this potential.5

Bull vs. Bear Case for Growth

The outlook for ASR’s growth can be viewed through two distinct lenses:

  • Bull Case: The massive investment in Cancún successfully modernizes the airport, enhances the passenger experience, and solidifies its position as the preferred gateway to the region, effectively marginalizing the competitive threat from Tulum. The Colombian and Puerto Rican operations continue their high-growth trajectory, driven by favorable tourism trends. ASR leverages its newly expanded capacity across the portfolio to drive both passenger volumes and commercial spending, leading to a new cycle of sustained earnings growth and dividend increases after the current investment phase concludes post-2028.
  • Bear Case: The new Tulum airport proves to be a formidable competitor, permanently capturing a significant share of passenger traffic that would have otherwise gone to Cancún. The broader Mexican tourism market stagnates due to persistent security concerns or a prolonged economic slowdown in the United States. Growth in the more mature Colombian and Puerto Rican markets decelerates to single-digit rates. In this scenario, ASR is left with underutilized, newly built assets, particularly at Cancún, leading to disappointing returns on its massive capital investment and pressuring its ability to grow future dividends.

Capital Allocation & Financial Strategy

ASR’s financial strategy is distinguished by its conservative balance sheet management, strong internal cash flow generation, and a clear commitment to returning capital to shareholders. This disciplined approach provides the company with significant financial flexibility to navigate its ambitious growth plans while maintaining robust shareholder returns.

Dividend Policy and Shareholder Returns

ASR has established itself as a significant dividend payer, making it attractive to income-oriented investors. The company has a track record of consistently increasing its distributions to shareholders. In April 2025, the Annual Shareholders’ Meeting approved a substantial ordinary cash dividend of Ps. 50.00 per share, a strong signal of confidence from the board.5

This follows a clear pattern of rising payouts. The total cash distributed as dividends grew from Ps. 2.5 billion in 2021 to Ps. 4.5 billion in 2022, and further to Ps. 6.0 billion in 2023.9 This commitment to shareholder returns has resulted in a dividend yield that is consistently among the highest in the airport sector and the broader infrastructure space, frequently cited in the 7% to 8% range.6

The high dividend yield can be interpreted in two ways. On one hand, it reflects the company’s immense cash-generating capability and a shareholder-friendly management team. On the other hand, a yield of this magnitude could suggest that the market is pricing in a lower future growth rate or higher perceived risk, thus valuing the company more for its current cash returns (like a utility) rather than for its future growth potential. This dichotomy is central to the valuation debate for ASR.

Debt Structure and Financial Flexibility

A cornerstone of ASR’s financial strategy is its remarkably conservative balance sheet. As of the first quarter of 2025, the company reported a negative Debt to LTM Adjusted EBITDA ratio of -0.5x, a metric that was also negative in the preceding quarter (-0.3x).5 This indicates that ASR’s substantial cash reserves exceed its total outstanding debt, a rare and enviable position for a company in a capital-intensive industry.

As of year-end 2023, consolidated outstanding indebtedness was Ps. 12.2 billion.9 The debt portfolio is prudently managed, consisting of a mix of floating-rate, peso-denominated term loans in Mexico and fixed-rate, U.S. dollar-denominated senior secured notes at its Puerto Rican subsidiary, Aerostar.9 This structure helps to naturally hedge some of the currency exposure within the business.

The company’s liquidity position is exceptionally strong. As of the end of the first quarter of 2025, ASR held a cash balance of Ps. 22.7 billion.5 This is further supported by access to significant undrawn revolving credit facilities.9 This deep pool of liquidity provides ASR with ample financial flexibility to fully fund its multi-billion peso capital expenditure program and its generous dividend policy without needing to access capital markets or strain its balance sheet. The company’s loan covenants, which require a leverage ratio below 3.50:1.00, are comfortably met.9

Capital Allocation Priorities

Management has demonstrated a clear and disciplined approach to capital allocation. The priorities appear to be well-defined:

  1. Fund Mandatory and Strategic Investments: The primary use of cash is to fund the committed capital expenditures outlined in the five-year Master Development Plans for its Mexican airports, as well as strategic investments in its international operations.9
  2. Return Excess Capital to Shareholders: After funding its investment programs, the company has shown a strong propensity to return the remaining free cash flow to shareholders through a substantial and growing dividend.5

The company’s powerful cash flow generation and low leverage allow it to pursue these two objectives in parallel, a key strength that differentiates it from more highly leveraged peers.

Risk Assessment

An investment in ASR is subject to a range of risks inherent to the airport industry, its geographic footprint, and the current political and economic climate. While the company’s diversification and financial strength provide significant mitigation, investors must carefully consider several key risk factors.

Regulatory and Political Risks

This has emerged as the most significant and least predictable risk facing ASR’s Mexican operations. The stable regulatory framework that has underpinned the value of Mexican airport concessions for over two decades is facing new challenges. The current Mexican administration has demonstrated a more interventionist approach to economic policy, as seen in the ongoing dispute with the U.S. Department of Transportation over slot management and cargo operations at the Mexico City airport.31 While this dispute does not directly involve ASR’s airports, it sets a concerning precedent. There is a non-zero tail risk that the government could seek to unilaterally amend the tariff-setting regulations or other key terms of the concession agreements for the private airport groups.7 Such an event would have a direct and materially adverse impact on ASR’s revenue and profitability.

Economic Cycles and Tourism Dependency

ASR’s financial performance is highly correlated with passenger traffic volumes. Consequently, the company is exposed to macroeconomic downturns in its key source markets.9 A recession in the United States would likely lead to a reduction in discretionary leisure travel, directly impacting traffic at Cancún and other tourist-focused airports. Similarly, a recession in Mexico would curtail domestic business and leisure travel.9 The business is also vulnerable to external shocks that can disrupt tourism, including:

  • Security Concerns: Perceptions of crime and violence in Mexico, even if not directly in tourist areas, can deter international visitors, as can travel advisories from foreign governments.9
  • Natural Disasters: ASR’s airports in southeastern Mexico and the Caribbean are located in a region susceptible to hurricanes and other severe weather events, which can cause both physical damage and prolonged business interruption.9
  • Public Health Crises: The COVID-19 pandemic provided a stark reminder of how quickly global travel can be halted by a health crisis, leading to a severe drop in passenger demand.9

Currency Fluctuations (MXN/USD)

ASR has significant exposure to the Mexican peso-U.S. dollar exchange rate. A large portion of its revenues, particularly international passenger charges in Mexico, are denominated in U.S. dollars but are collected and reported in Mexican pesos.9 This creates a complex exposure:

  • A sharp depreciation of the peso can cause ASR to breach its regulated maximum tariffs (which are set in pesos), potentially leading to regulatory penalties.9
  • A sharp appreciation of the peso reduces the peso value of its dollar-denominated revenues, which can limit the company’s ability to maximize its regulated income.9

    The Mexican peso has exhibited significant volatility in recent years, strengthening considerably post-pandemic before weakening in 2024 amid political uncertainty.43 This volatility directly impacts ASR’s reported earnings and cash flows.

Competitive and Concentration Risks

Despite its diversification, ASR remains heavily reliant on the performance of a single asset: Cancún International Airport.4 The recent inauguration of the Felipe Carrillo Puerto International Airport in Tulum introduces a direct and significant competitive threat for the first time. The new airport will compete for the same pool of tourists visiting the Mayan Riviera. The extent to which Tulum can capture market share from Cancún over the long term is a major uncertainty and a key risk to ASR’s future growth trajectory.6

Airline and Partner Dependency

ASR’s business is fundamentally dependent on the operational and financial health of its airline partners. The bankruptcy of a major carrier serving its airports, or a significant reduction in capacity due to economic pressures or fleet issues (such as the recent engine inspection mandates), could materially reduce passenger volumes and aeronautical revenues.18

Valuation Analysis

ASR’s valuation reflects a balance between its high-quality financial profile and the notable risks facing its core market. On most relative metrics, the company trades at a discount to its domestic peers, which may present an opportunity for value-oriented investors or signal appropriate caution from the market.

Relative Valuation Metrics

An analysis of ASR’s valuation multiples as of mid-2025 provides a mixed picture.

  • Price-to-Earnings (P/E) Ratio: ASR trades at a trailing twelve-month (TTM) P/E ratio in the range of 12x to 14x.6 This is a reasonable multiple for a stable infrastructure company. The company’s historical P/E ratio has shown significant volatility, falling to single digits during market downturns and spiking during the earnings trough of the pandemic, before normalizing in the current range.45
  • Enterprise Value to EBITDA (EV/EBITDA) Ratio: This is a preferred metric for capital-intensive businesses like airports because it is independent of capital structure and depreciation policies. ASR’s EV/EBITDA multiple is approximately 8.0x.39 A multiple below 10x is often considered attractive in the infrastructure space.46 The average for the Airport Operators & Services industry is cited as 8.49x, placing ASR directly in line with its global sector peers.47
  • Price-to-Book (P/B) Ratio: The company’s P/B ratio stands at approximately 3.3x.39

Peer Comparison Analysis

A comparison with ASR’s closest peers reveals a clear valuation discount.

  • Domestic Peers: ASR’s P/E ratio of ~13x is substantially lower than that of Grupo Aeroportuario del Pacífico (GAP), which trades at a P/E of approximately 24x, and Grupo Aeroportuario del Centro Norte (OMA), which trades at a P/E of around 20x.19 This valuation gap likely reflects the market’s concerns about the slowing traffic growth in ASR’s Mexican portfolio and the specific competitive and concentration risks associated with the Cancún airport.
  • International Peers: Compared to major international operators, ASR’s valuation appears more compelling. While its P/E ratio is similar to that of Fraport AG (~14x), ASR’s EBITDA margins are more than double, suggesting significantly higher profitability and operational efficiency.19 Aena SME S.A. trades at a higher multiple, further highlighting the relative value in ASR, particularly on an EV/EBITDA basis.

Dividend Yield

The most striking feature of ASR’s valuation is its dividend yield. At over 8%, it is exceptionally high for an infrastructure asset and dramatically exceeds the yields offered by its domestic peers GAP (~2.0%) and OMA (~4.2%).19 This premium yield is a primary attraction for income-focused investors and serves as a significant component of the total return proposition.

Valuation in Context

The interpretation of ASR’s valuation depends heavily on an investor’s outlook on the identified risks and opportunities.

  • Bear Case: The current valuation is a fair reflection of the considerable risks. The discount to domestic peers is justified by the clear deceleration of traffic in Mexico, the unquantified but real competitive threat from the new Tulum airport, and the rising regulatory risk premium. From this perspective, the high dividend yield is not a sign of a bargain but rather compensation for lower future growth prospects and could be a potential value trap if earnings come under pressure.
  • Bull Case: The stock is currently undervalued. The market is excessively penalizing ASR for short-term weakness in its Mexican operations while failing to properly credit the strong growth and strategic importance of its international assets in Colombia and Puerto Rico. The current valuation provides an attractive entry point into a world-class infrastructure operator with a fortress balance sheet, superior profitability, and a secure and substantial dividend stream.

Management Quality & Corporate Governance

The quality and experience of the management team, coupled with a transparent governance structure, are critical components of the investment case for ASR. The company benefits from a seasoned leadership team with a strong track record of operational and strategic execution.

Management Team Experience and Track Record

ASR’s senior management team is characterized by its stability and deep industry experience. Many executives have long tenures with the company and extensive backgrounds in the Mexican infrastructure and transportation sectors.9 Adolfo Castro Rivas, the Chief Executive Officer, has been with ASR for many years, having previously served as the Chief Financial Officer. This provides him with a profound understanding of the company’s operational and financial intricacies.9 The leadership team has successfully navigated numerous challenges, including the global financial crisis, the COVID-19 pandemic, and various natural disasters, while consistently delivering on large-scale capital projects. Their most notable strategic success has been the seamless integration of the major acquisitions in Puerto Rico and Colombia, which have fundamentally reshaped the company’s growth profile.

Strategic Vision and Execution

Management has demonstrated a clear and consistent strategic vision focused on profitable growth. This strategy is twofold: pursuing organic growth through disciplined investment in its existing assets via the Master Development Plans, and seeking inorganic growth through strategic international acquisitions. The success of the latter highlights strong capabilities in strategic planning, due diligence, and capital allocation. Operationally, the team’s ability to maintain industry-leading EBITDA margins and a fortress balance sheet, even while executing multi-billion-peso investment programs and paying substantial dividends, speaks to a culture of strong financial discipline and operational efficiency.

Corporate Governance and Transparency

As a foreign private issuer listed on the New York Stock Exchange (NYSE), ASR is subject to the reporting requirements of the U.S. Securities and Exchange Commission (SEC). The company files an annual Form 20-F, which provides a comprehensive and audited overview of its operations, financials, and risk factors, ensuring a high degree of transparency for international investors.48

The Board of Directors is composed of a mix of representatives from the company’s strategic partner, Inversiones y Técnicas Aeroportuarias (ITA), and a strong contingent of independent directors.9 The independent directors include highly respected figures from the Mexican business and financial establishment, such as Ricardo Guajardo Touché (former President of Grupo Financiero BBVA) and Guillermo Ortiz Martínez (former Governor of the Bank of Mexico), who also serves as the financial expert on the Audit Committee.9 This composition suggests a robust governance framework with experienced oversight.

ASR maintains an active investor relations program, providing regular and timely information to the market through quarterly earnings reports and conference calls, monthly passenger traffic releases, and investor presentations available on its website.5

Concluding Remarks

Grupo Aeroportuario del Sureste presents a complex and multifaceted investment profile. The company is undeniably a high-quality infrastructure operator, distinguished by a financially robust balance sheet, world-class profitability margins, and a management team with a proven record of strategic execution. Its successful diversification into the high-growth markets of Colombia and Puerto Rico has been a testament to its long-term vision and has created a more resilient and geographically balanced enterprise.

The core debate for investors is now centered on the interplay between the company’s established strengths and the significant, evolving challenges in its primary market. The investment thesis can be framed by two opposing narratives:

The bull case is predicated on the company’s manifest financial strength and strategic positioning. It highlights the successful international diversification, which is now driving consolidated growth. It points to a fortress balance sheet with negative net debt, which provides immense flexibility to fund a massive, and potentially highly accretive, capital expenditure program. It emphasizes the industry-leading margins that provide a substantial cushion against shocks. Finally, it rests on a very attractive and well-covered dividend yield, which offers a significant and tangible return to shareholders.

Conversely, the bear case is rooted in the deteriorating outlook for ASR’s most important asset, Cancún International Airport. It focuses on the stagnating passenger traffic trends in Mexico, the emergence of a direct and credible competitive threat from the new Tulum airport, and, most critically, a tangible increase in the political and regulatory risk premium for all Mexican infrastructure assets. This view posits that the market’s valuation discount to peers is justified and that the high dividend may not be sustainable if the returns on the new Cancún investments fall short of expectations.

To form a definitive investment conclusion, one must resolve two critical questions. First, is the current valuation discount relative to peers, combined with the substantial dividend yield, sufficient compensation for the heightened competitive and regulatory risks facing the Mexican operations? Second, will the growth momentum from the international portfolio in Colombia and Puerto Rico be powerful and durable enough to drive consolidated earnings growth forward, even if the Cancún hub underperforms expectations over the next investment cycle? The answers to these questions will ultimately determine the long-term investment merits of ASR.
