Grupo Aeroportuario del Sureste (ASR) Stock Price & How to Invest

Grupo Aeroportuario del Sureste, which operates under the ASUR brand, holds concessions to operate, maintain, and develop 16 airports across the Americas. Its portfolio includes nine airports in southeastern Mexico (led by Cancun, plus Cozumel, Merida, Oaxaca, Veracruz, and others), six airports in northern Colombia through its Airplan unit (including the Medellin metro area hubs), and a 60% stake in Aerostar, which runs San Juan's Luis Munoz Marin International Airport in Puerto Rico. Roughly 58% of revenue comes from Cancun alone, making ASR heavily tied to leisure travel to Mexico's Caribbean coast. Revenue splits between aeronautical fees (charges tied to passengers and aircraft) and a fast-growing non-aeronautical segment (retail leasing, parking, advertising, and commercial services).

The investment picture is that of a concession-protected infrastructure operator with high margins, strong free cash flow, low leverage, and a regular dividend, set against real cyclical and regulatory sensitivity. Passenger traffic and non-aeronautical revenue per passenger drive the top line, while the company invests heavily through multi-year committed capex plans negotiated with regulators. The key debates are the durability of Cancun-led Mexican tourism demand (international arrivals have softened recently), the outcome of Mexican maximum-tariff and concession-fee changes, and whether faster-growing Colombia and resilient Puerto Rico can diversify the mix over time.

The single largest risk is Cancun concentration: about 58% of revenue derives from one airport tied to leisure travel, so any sustained slowdown in Mexican Caribbean tourism hits results directly. International arrivals to Cancun and other Mexican beach destinations have shown recent double-digit declines, reflecting softer US travel demand and rising competition from other sun-and-beach markets. Mexican regulatory risk is material: authorities amended the tariff base regulation and raised the concession fee on regulated revenues (from 5.0% to 9.0% starting in 2024), and future maximum-tariff reviews could pressure returns. As an ADR of a Mexican company, the stock also carries peso currency risk, and required multi-year capital investment plans commit large sums regardless of the traffic cycle.

9 analysts publish price targets on ASR, averaging $351.20 against a $275.62 price as of August 2026, or +27.4%.

A price target is what an analyst published on a date, not a prediction, and sell-side ratings skew positive across the whole market.

We give no verdict on Grupo Aeroportuario del Sureste. Both cases are real, which is why the question is contested at all, so here is the strongest version of each.

The case for buying. Concession-protected airport franchise. ASR operates its airports under long-dated government concessions that function as effective local monopolies, with regulated maximum tariffs set over multi-year periods. The most optimistic published target, $392.27, assumes this works close to its best case.

The case against. The single largest risk is Cancun concentration: about 58% of revenue derives from one airport tied to leisure travel, so any sustained slowdown in Mexican Caribbean tourism hits results directly. The most pessimistic target, $315.00, is roughly what ASR is worth if this bites instead.

A simple financial snapshot. These are approximations and refresh quarterly; for current figures see Grupo Aeroportuario del Sureste's investor relations page or your broker.

• Revenue (FY2025): ~Ps.37 billion (~$2.0B USD)
• Q1 2026 revenue: ~Ps.8.9 billion (+0.8% YoY)
• Net income (FY2025): ~Ps.10.5 billion
• Net debt / LTM EBITDA: ~0.8x
• P/E (approx): ~17-19x
• Market cap (approx): ~$8-9 billion

Full-year 2025 revenue grew about 19% to roughly Ps.37 billion, though reported earnings declined versus the prior year, partly reflecting the higher concession fee and cost pressures. The stock trades at a mid-to-high-teens price-to-earnings multiple, typical for a regulated infrastructure operator with monopoly-like concessions. Figures are approximate and based on public reporting; the ADR is denominated in US dollars while the underlying results are reported in Mexican pesos.

Other names that sit close to ASR: same theme, named as a direct competitor, or held beside it in the same funds. Each entry says which. Worth a look if you are thinking about diversification within a thesis rather than concentration on one ticker.

There are three common ways to get ASR exposure. Buy shares (or fractional shares) directly at any major broker. Hold an ETF that includes it, which spreads the position across many companies. Or build it into a focused thematic portfolio, so ASR sits alongside other stocks that express the same thesis.

Walnut takes the portfolio route. Describe a thesis where ASR fits (for example “AI infrastructure” or “dividend-growth large-caps”) and the AI proposes 5 to 6 constituents with target weights. You review the plan and fund it through your own broker when you're ready.

ASR is an established, cash-generative airport monopoly-by-concession whose long-term case rests on Latin American air travel demand, tempered by heavy Cancun dependence and Mexican regulatory risk.

Whether ASR is worth buying today depends more on your time horizon and what you already hold than on any single call. We walk through valuation, what would have to go right, and the risks in is ASR a buy or a sell?, and where the stock could go from here in the ASR stock forecast.
