Braskem announces that Mario Augusto da Silva is its new Chief Financial and Investor Relations Officer, succeeding Marcela Drehmer.

The change is a natural part of the process of renewing leaderships and planned succession that characterizes the Odebrecht Entrepreneurial Technology (TEO). The main pillars of Braskem's financial management, which include a firm commitment to financial discipline and supporting the growth plan, remain the Company's key priorities.

Awarded a bachelor's degree in Business Administration from the University of Salvador (Unifacs) in Bahia in 1998, Mario Augusto da Silva has extensive knowledge of the petrochemical industry and Braskem, where he began working while the Company was still being formed company, in 2001, where he stayed until 2005, when he left to pursue his MBA at Harvard Business School (concluded in 2007).

Upon returning, he became chief financial officer at Construtora Norberto Odebrecht. Later, he served as chief financial officer at the companies Odebrecht Óleo & Gás and Odebrecht Infraestrutura - América Latina, where he worked until recently.

Marcela Drehmer, after having served three years as chief financial officer of Braskem, will assume the new challenge of serving as chief financial officer of Odebrecht S/A, replacing Felipe Jens, who will become the new leader of Odebrecht Properties. While she was at the helm of Braskem's financial department, the Company obtained investment grade ratings from the three major rating agencies: S&P, Moody's and Fitch. In recent months, Braskem has been strengthening its focus on reducing the level of financial leverage and maintaining its long debt profile, which will remain the priorities of the incoming administration.
