Kathmandu Capital stated the following regarding Grupo Aeroportuario del Centro Norte, S.A.B. de C.V. (NASDAQ:OMAB) in its second quarter 2025 investor letter:

"Grupo Aeroportuario del Centro Norte, S.A.B. de C.V. (NASDAQ:OMAB) is a leading airport operator in Mexico, founded in 1998 as part of the country’s airport privatization initiative. The company operates 13 airports under a 50-year concession granted by the Ministry of Communications and Transportation (SCT), with the possibility of a 50-year extension. Under this agreement, OMAB must pay a concession tax (up recently from 5% to 9% of gross revenue beginning in 2024), provide continuous and non-discriminatory services, maintain infrastructure, and fulfill investment obligations under its Master Development Program (MDP). These MDPs are reviewed every five years, during which the SCT establishes minimum capital spending requirements for the next period.

Our investment thesis for OMAB is threefold. First, airports are typically considered regional monopolies because they are the exclusive providers of aviation infrastructure within a given geographic area. High capital requirements, strict regulatory frameworks, land constraints, and environmental concerns make it impractical to build competing airports. This structural exclusivity creates substantial and durable barriers to entry. Airlines and passengers are also captive to use the existing facility, making the business especially sticky with pricing power."
