The P/E of 12.69 is roughly 30% below PAC's 17.93 and 20% below OMAB's 15.61, while EV/EBITDA of 7.70 is similarly discounted. This gap may reflect market concerns over regulatory changes and Tulum competition, but the PEG of 0.32 suggests the market is pricing in minimal growth. Given the strong recent revenue acceleration, the valuation appears to embed a pessimistic scenario that may not be justified by current fundamentals.

Gross margin fell to 41.9% in 2026Q2 from 67.9% in 2025Q2, likely due to IFRIC 12 construction revenue and cost recognition, which inflates revenue without affecting profit. Excluding construction, underlying margins are likely higher. Net margin of 24.0% is still strong, supported by low leverage and efficient cost control. Investors should monitor whether margin compression is temporary or signals a structural shift in the regulatory cost base.

The wide quarterly swings in ROIC are driven by the timing of concession payments and construction activity, not by deterioration in the core business. ROE of 4.7% in 2026Q2 is low on a quarterly basis but annualized would be near 19%, consistent with historical levels. The fortress balance sheet and high cash position mean returns are understated by excess liquidity; adjusting for cash, returns on operating capital are likely higher. This suggests the company is compounding value, albeit with volatility.

DSO rose to 64 days in 2026Q2 from 48 days in the prior quarter, possibly reflecting timing of receivables from airlines and concessionaires. DPO is low at 11 days, indicating limited supplier financing, but the negative CCC in some quarters (e.g., -93 days in 2025Q1) shows the company can operate with negative working capital when DPO spikes. Asset turnover of 0.11 is low due to the large intangible base from concessions, but this is typical for the sector and not indicative of operational inefficiency.

Total debt of $34.5B against equity of $41.5B is modest, and the D/EBITDA of 7.29 is elevated only because EBITDA is depressed by construction accounting; on a normalized basis, leverage is far lower. Interest coverage of 7.09x is comfortable, though it has declined from the extraordinary levels of 2024 (e.g., 699x in 2024Q4) due to higher debt and lower EBITDA. The company's low leverage insulates it from rising rates and provides capacity for future investments or shareholder returns.

Liquidity remains robust, though cash has declined from $19.8B in 2025Q2, reflecting heavy dividend payouts and capex. The current ratio has been consistently above 2.5 over the past year, indicating the company can cover short-term obligations multiple times over. Even under a severe traffic downturn, the cash position and low debt would allow ASR to maintain operations and continue investing without distress. This supports the fortress balance sheet assessment.

The discount is notable given ASR's similar or better profitability (net margin 24.0% vs. 30.7% for PAC and 33.5% for OMAB) and far lower leverage (D/E 0.71% vs. 1.88 and 1.19). This may reflect concerns about regulatory risk and Tulum competition, but also ASR's higher exposure to US consumer discretionary spending. The gap could narrow if ASR continues to deliver strong growth and maintains margins, or widen if competitive pressures intensify.
