The gap between the 23.23 trailing P/E and the 1.22 forward P/E suggests the forward estimate may rest on inconsistent or incomplete inputs rather than a genuine earnings step-up. Against OMAB, which trades at 18.43 times earnings and 11.09 times EV/EBITDA, PAC appears priced at a modest premium on trailing measures. The 0.59 PEG and 9.35 price-to-book point to a market that is paying for returns on a comparatively large asset base rather than for near-term growth alone.

Margins in the 42 to 48 percent operating band across most recent periods suggest a concession-style cost structure with substantial fixed components, so operating leverage to traffic recovery may be meaningful. The 2025Q4 and 2024Q4 anomalies, including negative gross margin and a 137 percent operating margin, indicate these headline figures should be read with caution rather than averaged naively. Net margin of roughly 24 to 29 percent is strong against OMAB's 33.5 percent, but the gap points to differences in financing cost and tax burden as much as operations.

Total assets appear to have expanded sharply, with goodwill rising to roughly $48.8 billion, which would mechanically dilute return ratios even if underlying earnings held. This suggests investors should monitor whether acquired capital is generating returns comparable to the historical base. Against OMAB's 31.7 percent ROIC, PAC's current 3.7 percent is markedly lower and warrants further investigation into whether the step-up reflects reporting discontinuity or genuine capital deployment.

Rising absolute debt alongside a lower debt-to-equity ratio suggests equity growth may have outpaced borrowing, though the shifting denominator makes this conclusion tentative. Interest coverage of 4.47 times in 2026Q3 is adequate but has fluctuated between 3.28 and 5.36 across recent quarters, so debt service comfort appears stable rather than improving. Investors should monitor refinancing exposure given the scale of debt relative to recent operating income, though the supplied data does not disclose maturity profiles.

A current ratio below one, combined with a quick ratio that equals the current ratio in every period, suggests inventory is negligible for this business model, so liquidity depends on cash and receivables against current liabilities. The position appears more dependent on operating cash generation and timely access to funding than a conventional industrial balance sheet. Under severe stress, a sustained decline in traffic-driven receipts could tighten coverage, though the data does not allow a definitive stress test.
