January 18, 2016

Lightweight metals leader Alcoa (NYSE:AA) today announced that Karl
Tragl will become President of the Company’s Transportation and
Construction Solutions Group. He succeeds José Drummond, who resigned

Tragl joins Alcoa from Bosch Rexroth AG, Bosch’s $6 billion automation

since 2010. While there, he grew revenues significantly across a
customer base that spans most of Alcoa’s major markets, including
construction and commercial transportation. Highly respected by

solutions, his insights are expected to help shape the expansion of
Alcoa’s digitization, 3-D printing and other additive manufacturing
innovations.

“Karl Tragl is the ideal executive to lead our Transportation and
Construction Solutions businesses as they pursue a wide variety of
growth opportunities worldwide,” said Klaus Kleinfeld, Alcoa Chairman
and Chief Executive Officer. “Having led a highly successful global
automation technology business that served the construction and
commercial transportation industries, Karl will build on Alcoa’s strong
innovation edge to drive profitable growth into new international
markets. He also brings knowledge and experience that will be invaluable
to Alcoa’s current initiatives to tap the tremendous potential of
additive manufacturing and digitization for our businesses and our
customers.”

Prior to his six years as CEO, Karl served in a progression of
challenging roles at Bosch Rexroth. Earlier he was Partner of Siemens
Management Consulting. Tragl began his career as an engineer at the
German Aerospace Research Center, graduating with a PhD in Electrical
Engineering at Kaiserslautern University. He also has attended executive
programs at the Business Schools of both Duke and Carnegie Mellon
Universities.
