Grupo Aeroportuario del Sureste, S. A. B. de C. V. (ASR) Income Statement

Growth reaccelerated from a soft 2.6% in 2026Q1 to 10.4% and then 17.1%, a cadence consistent with the winter tourism peak at Cancun rather than a step-change in terminal capacity, so the current run-rate appears cyclical in nature. The 31.2% print in 2024Q4 came off a $7.5B base and has not been repeated, implying the durable trend sits closer to mid-to-high teens. Investors should judge whether growth is being carried by commercial revenue per passenger or simply by raw throughput, since only the former would signal genuine pricing power.

Absolute gross profit actually fell from $8.6B in 2025Q1 to $4.0B in 2026Q3 even as revenue rose, which means the reported margin compression reflects real earnings power at the gross line, not just a denominator effect. Because the peer set (PAC at 77.1%, OMAB at 70.1%) sits far above ASR's 39.0% latest reading, cross-sectional margin comparisons look unreliable until the treatment of concession and construction-related costs is normalized. The parallel spike in SG&A to $3.5B in the same 2025Q1 quarter reinforces the view that classification boundaries have moved, and further investigation into segment disclosure is warranted.

This pattern is the opposite of the operating leverage typically expected from a concession asset with a fixed cost base, implying that incremental revenue is being absorbed by cost lines that are scaling faster than sales. Operating margin has accordingly compressed from 54.8% in 2024Q3 to 37.3% in 2026Q3, and since SG&A remains only about 1.7% of revenue, the pressure is concentrated in COGS rather than discretionary overhead. If the cost lines driving this are concession taxes or mandated infrastructure spend, the room for management to restore leverage through expense discipline may be limited.
