The Wagner Firm announces an investigation on behalf of Graña y Montero S.A.A. (“Graña y Montero” or the “Company”) (NYSE: GRAM) investors concerning the Company and its officers’ potential violation of federal securities laws.

On February 24, 2017, a report disclosed that the Company knew of bribes paid by a partner infrastructure developer Odebrecht in Peru, citing testimony of former Odebrecht executive Jorge Barata.

On this news, Graña y Montero shares fell nearly 35% on February 24, 2017.
