Form 20-F regulatory

"The Company also filed its Form 20-F for the year ended December 31, 2025, with the U.S. Securities and Exchange Commission (SEC)."

Form 20-F is the standardized annual disclosure that non-U.S. companies must file with the U.S. securities regulator when their shares are traded in the U.S.; it contains audited financial statements, a plain-language description of the business, management discussion, governance details and key risk factors. It matters to investors because it provides a consistent, comparable company “report card” and rulebook, helping buyers assess financial health, governance and risks before investing.

Annual Report financial

"it filed its Annual Report for the year ended December 31, 2025, with the National Banking and Securities Commission (CNBV) and with the Mexican Stock Exchange (BMV)."

An annual report is a comprehensive, year-end document a publicly traded company issues that presents its financial statements, management’s discussion of results, business strategy, and key risks. Investors use it like a combined report card and roadmap to judge a company’s financial health, how it makes money, and whether its plans and risks are likely to raise or lower future value, helping inform buy, hold, or sell decisions.

National Banking and Securities Commission (CNBV) regulatory

"filed its Annual Report for the year ended December 31, 2025, with the National Banking and Securities Commission (CNBV)"

Mexican Stock Exchange (BMV) regulatory

"filed its Annual Report for the year ended December 31, 2025, with the National Banking and Securities Commission (CNBV) and with the Mexican Stock Exchange (BMV)."

NASDAQ Global Select Market financial

"OMA is listed on the Mexican Stock Exchange (OMA) and on the NASDAQ Global Select Market (OMAB)."

A Nasdaq Global Select Market listing is the highest tier of stocks on the Nasdaq exchange, reserved for companies that meet the strictest financial, reporting and governance standards. For investors, it acts like a premium quality label—signaling larger, more transparent and better-governed companies that tend to offer greater liquidity and lower perceived risk compared with lower-tier listings, making it easier to buy, sell and evaluate shares.

foreign private issuer regulatory

"FORM 6-K REPORT OF FOREIGN PRIVATE ISSUER PURSUANT TO RULE 13a-16 OR 15d-16"

A foreign private issuer is a company organized outside the United States that meets tests showing it is primarily foreign-controlled and therefore qualifies for a different set of U.S. reporting rules. For investors, that means the company files less frequent or differently formatted disclosures with U.S. regulators and may follow home-country accounting and governance practices, so buying its stock is like dining at a well-reviewed restaurant that follows its home kitchen’s rules instead of the local menu — you get access but should check what standards apply.
