Alcoa has announced that Graeme Bottger has been named executive vice president and president of Global Business Services (GBS). Assistant controller Robert Collins will succeed Bottger in the role of vice president and controller. These changes take effect on 21 October. Mark Davies, who has been president of GBS since 2012, will be taking a role outside of the company.

As GBS president, Bottger will oversee Alcoa's procurement, shared services and information technology organisations. He has held a wide variety of corporate and business unit operational and financial roles since joining Alcoa in 1980.

Collins has been assistant controller since 2009 with responsibility for the company's global financial accounting policies. He joined Alcoa in 2005.

"Graeme and Bob have successful track records in increasingly challenging roles and are ideally qualified to lead functions critical to Alcoa," said Klaus Kleinfeld, Alcoa chairman and chief executive officer. "Both have been instrumental to the success of our cash sustainability programme, which has strengthened Alcoa's cost structure and balance sheet. These appointments demonstrate Alcoa's strong talent pipeline."

Bottger was named controller in July 2010 and has had oversight of the accounting and financial planning and analysis departments that play a key role in enabling Alcoa to be the first major company to report its earnings each quarter. A former chief financial officer of engineered products and solutions, he has also worked in Alcoa's GBS, procurement, IT and sales organisations in Australia and the US.

Prior to his role as assistant controller, Collins was involved in M&A deals as Alcoa's director of financial transactions and policy. Before Alcoa, Collins worked in the audit and M&A practices at PricewaterhouseCoopers for 14 years.

Bottger will report to Klaus Kleinfeld. Collins will report to Alcoa executive vice president and chief financial officer, William Oplinger.
