Graña y Montero: that name no longer represents us

● The company apologized to the country for the wrong decisions and unlawful acts of executives who are no longer part of the Company.

● As a further step in their deep transformation process, the company will no longer use the name Graña y Montero. This name does not represent the new company that is now beginning a process of transition to a new brand.

Lima, February 3, 2020.- Graña y Montero took another step in its process of deep transformation. The company apologized to all Peruvians for the damages caused, bad decisions or illegal acts of executives who are no longer in the organization and has decided to change its identity.

"We do not want to remain in silence, nor forget everything that happened (...). We are still here because we want to reinvindicate with the country. We are committed to Peru and we are collaborating with justice, with total transparency on whatever is needed, so that whatever has to be paid is paid. From now on, we are no longer Graña y Montero. That name no longer represents us", says the spot published today.

That name does not represent the new company that is now starting a transition process towards a new brand. This new company will remain anchored in the commitment to Truth, Transparency and Integrity, which was assumed more than three years ago by its new administration. The contribution to the clarification of the facts will remain intact.

"This is the result of the severe transformation process we started three years ago and which has matured today. We have made significant changes in the organization, sold important assets to meet our commitments and implemented new corporate governance policies to ensure that what happened will never happen again," said Augusto Baertl, Chairman of the Board of Directors of the company.

The process of changing the name began with the removal of the orange logotype and its letters and will continue with the approval of a new name by the company's corporate bodies.

The more than 17,000 employees of the company, its customers, business partners and suppliers are the main guarantee for the future. Thanks to their commitment and trust, we have solved great challenges and achieved more than US$900 million in new contracts awarded during 2019 and a backlog plus recurrent businesses of US$2,094 million - approximately 1.7 years of revenues for the company.
