OMA (ISIN MX01OM000018) was trading at EUR 9.83 at Lang & Schwarz on October 15, 2026, at 11:03 a.m. CEST. The Mexican airport operator appointed EY as its external auditor for fiscal year 2026 on October 9, 2026, according to StockTitan.

Audit change follows weaker traffic

The auditor switch is effective for fiscal year 2026. Mancera, a member of Ernst & Young Global Limited, replaces Galaz, Yamazaki, Ruiz Urquiza, the Deloitte affiliate previously responsible for OMA's external audit, according to the October 9 filing carried by StockTitan. The company described the move as part of an effort to strengthen audit processes and corporate governance.

OMA's recent operating data provide the more immediate business context. On September 29, 2026, the company had completed the rollout of a digital operating suite across its 13 airports, according to El-Fondo.

What does the traffic mix mean?

OMA reported a 4.80 percent year-over-year decline in passenger traffic for September 2026. Domestic traffic fell 5.90 percent, while international traffic rose 2.80 percent, according to the company's October 7 filing reported by StockTitan. Commercial passengers represented 99.40 percent of the total, leaving general aviation at 0.60 percent. The split points to domestic demand as the main operating pressure, even as international traffic expanded.

Three dated OMA developments

On September 29, 2026, OMA completed digital deployment across 13 airports. On October 7, 2026, it reported a 4.80 percent passenger decline for September. On October 9, 2026, it appointed EY as auditor for fiscal year 2026.

When are results due?

OMA is expected to report third-quarter results in the week of October 19, 2026, according to El-Fondo. That release should put the September traffic trend alongside the group's financial performance.
