We hereby inform as a Relevant Information Communication that on Tuesday, November 19, 2019 Adexus S.A. (a subsidiary of Grupo Graña y Montero founded in Chile) filed an application for reorganization under Law No. 20.720 with the Chilean courts of justice.

The reorganization allows companies with temporary liquidity problems to obtain financial protection for a period of 30 days, extendable for a period of 60 days, with the support of their creditors, to prepare, propose and negotiate a plan to restructure their assets and liabilities.

For some time now, Adexus S.A. has been experiencing short-term liquidity problems. The situation Chile is going through has aggravated this problem, affecting the company's level of budgeted activity and therefore worsening its liquidity situation.  If the request for reorganization of Adexus S.A. is accepted, the company will attempt to negotiate and reach an agreement on a restructuring plan as soon as possible, in order to give operational continuity to the company.

As previously reported, Grupo Graña y Montero's investment in Adexus S.A. has been declared as an asset held for sale and therefore, exceptionally, Grupo Graña y Montero has taken this decision, with the expectation to complete the sale of this asset as soon as possible, in order to continue with its strategy of focusing on the Engineering and Construction, Infrastructure and Real Estate businesses.

Sincerely yours,

Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned, thereunto duly authorized.

GRAÑA Y MONTERO S.A.A.
