Alcan joins Rio Tinto to create global aluminium leader

Alcan today joined the Rio Tinto group following the successful Offer for Alcan by a subsidiary of Rio Tinto.  The expanded aluminium product group, formed by the combination of Alcan and Rio Tinto’s existing aluminium assets, today became the new global leader in aluminium and will be known as Rio Tinto Alcan.

Rio Tinto chief executive, Tom Albanese and Rio Tinto Alcan chief executive, Dick Evans hosted special events at Rio Tinto Alcan’s Montreal headquarters and highlighted the  opportunities created by bringing Alcan into the Rio Tinto Group, and the potential for continued strong growth in the aluminium sector. Similar employee events took place in Brisbane.

“I am proud to be here to welcome Alcan employees into the Rio Tinto family”, said Tom Albanese. “They have built a company whose values we share.”

“Rio Tinto’s strategy is to create shareholder value through investing in high quality, long life, low cost assets, and Alcan is a terrific addition to the Rio Tinto group. Together, we have a fantastic opportunity to build an even stronger global aluminium business through profitable and sustainable growth.”

“I am personally delighted to have the opportunity to be part of the new leader in the global aluminium industry, Rio Tinto Alcan,” said Dick Evans. “With our attractive cost position, strong technology portfolio, complementary refining and smelting assets, and a strong growth pipeline, Rio Tinto Alcan’s mission is to create maximum sustainable value for Rio Tinto shareholders and to fulfil our mutual commitments to all of our stakeholders,” he added.

The offer for Alcan, which was recommended by the Alcan Board, was announced by Rio Tinto on 12 July 2007 and has received approvals from relevant authorities and governments globally and the support of Rio Tinto shareholders.

Both Rio Tinto and Alcan have been recognised as leading stewards of the environment and the communities in which they operate, and in putting worker safety at the top of the priority list, and this philosophy would be maintained, stressed Tom Albanese and Dick Evans.

“Rio Tinto Alcan will maintain commitments to excellence in health, safety and environmental performance, working together to ensure the economic, environmental, and social sustainability of the communities in which we operate,” said Dick Evans.

Rio Tinto in Canada

Rio Tinto is committed to investing in the Rio Tinto Alcan presence in Canada, particularly in the Provinces of Québec and British Columbia, in addition to locating the headquarters of the combined aluminium product group in Montréal. The product group’s aluminium smelting technology research and development headquarters will also be located in Québec.

Rio Tinto in Australia

Australia’s strengths in bauxite extraction, alumina refinery operations and project development will be enhanced by locating the combined global bauxite and alumina business and associated research and development activities in Brisbane.

Rio Tinto has a significant programme of capacity growth in place following the recent announcement of the expansion at Rio Tinto’s Yarwun alumina refinery, and the ongoing bauxite capacity expansion at Weipa.

Rio Tinto in France

Rio Tinto has a strong, long-term commitment to France, which it believes provides an attractive environment in which to invest, conduct business and engage in world-leading research and development. Rio Tinto recognises France’s long history of expertise and research and development in aluminium technology, particularly “new cell” smelting technology and is committed to building on French innovation in this area. Rio Tinto has had operations in France since 1988 through its Talc de Luzenac business based in Toulouse.

Forward looking statements

This announcement contains statements which constitute “forward-looking statements” about Rio Tinto and Alcan. Such statements include, but are not limited to, statements with regard to the outcome of the proposed Offer, any statements about cost synergies, revenue benefits or integration costs, capacity, future production and grades, projections for sales growth, estimated revenues and reserves, targets for cost savings, the construction cost of new projects, projected capital expenditures, the timing of new projects, future cash flow and debt levels, the outlook for minerals and metals prices, the outlook for economic recovery and trends in the trading environment and may be (but are not necessarily) identified by the use of phrases such as “will”, “intend”, “estimate”, “expect”, “anticipate”, “believe” and “envisage”.  By their nature, forward-looking statements involve risk and uncertainty because they relate to events and depend on circumstances that will occur in the future and may be outside the control of Rio Tinto or Alcan. Actual results and developments may differ materially from those expressed or implied in such statements because of a number of factors, including the outcome of the proposed Offer, revenue benefits and cost synergies being lower than expected, integration costs being higher than expected, levels of demand and market prices, the ability to produce and transport products profitably, the impact of foreign currency exchange rates on market prices and operating costs, operational problems, political uncertainty and economic conditions in relevant areas of the world, the actions of competitors, activities by governmental authorities such as changes in taxation or regulation and such other risk factors identified in Rio Tinto’s most recent Annual Report on Form 20-F filed with the SEC or Form 6-Ks furnished to the SEC or Alcan’s most recent periodic and current reports on Form 10-K, 10-Q or 8-K filed with the SEC (as the case may be). Forward-looking statements should, therefore, be construed in light of such risk factors and undue reliance should not be placed on forward-looking statements.

Nothing in this announcement should be interpreted to mean that the future earnings per share of Rio Tinto will necessarily match or exceed its historical published earnings per share.
