Board of Directors financial

"its Board of Directors approved today the following decision"

The Board of Directors is a group of people chosen by a company's owners to help make big decisions and oversee how the company is run. They act like a team of advisors or managers, making sure the company stays on track and meets its goals. Their choices can influence the company's success and how it grows.

Corporate Vice Presidency financial

"the position of Payments, Flows and Insurance Corporate Vice Presidency of Bancolombia"

foreign private issuer regulatory

"REPORT OF FOREIGN PRIVATE ISSUER PURSUANT TO RULE 13a-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.

subsidiary financial

"Bancolombia S.A., a subsidiary of Grupo Cibest, announced the creation"

A subsidiary is a company that is controlled or owned by a larger company, known as the parent company. Think of it like a branch or division of a bigger organization; it operates separately but is ultimately guided by the parent. For investors, understanding subsidiaries helps clarify how a larger company is structured and where its resources and risks are concentrated.
