Grupo Cibest S.A. ("Grupo Cibest") informs that today it entered into a promise to purchase shares agreement with Inversiones Cuscatlán Centroamérica S.A. for the sale of 100% of the shares of Banistmo S.A. ("Banistmo").

Banistmo began operations in 1973 and is one of Grupo Cibest's financial entities located in the Republic of Panama, after being acquired in October 2013.Banistmo has positioned itself as one of Panama's leading banks, offering a wide range of financial services under the supervision of the Superintendency of Banks of Panama.

Inversiones Cuscatlán Centroamerica S.A., a company incorporated in 2001 in Panama, with presence in Central America, acting as the holding entity of various banking and insurance businesses in the region. These businesses include Banco Cuscatlán in El Salvador, Banco Inmobiliario in Guatemala, Banco Cuscatlán in Honduras, Seguros e Inversiones S.A. (SISA) in El Salvador, and Banco La Hipotecaria in Panama, El Salvador, and Colombia. There is no material relationship between these entities and Grupo Cibest and its affiliates.

The agreed sale price is USD $1.418 billion, representing a Price/Earnings ratio for the last twelve months as of September 30, 2025 of 17.1x and a Price/Book Value ratio of 1.2x. The purchase price will be subject to customary closing adjustments.

The purchase price will be paid in full on the closing date of the transaction, once the required regulatory approvals in Panama are obtained other customary conditions under the SPA are satisfied.

As Grupo Cibest has now completed the previously disclosed spin-off of Valores Banistmo (which is no operating as a separate affiliate of Grupo Cibest and part of the "Cibest Capital" brand), from Banistmo , it is not part of the transaction and will continue to be a key component of Grupo Cibest's capital markets
