PRESS RELEASE

For your business and technology editors

ABB consolidates global transformer business

• ABB adapts to overcapacity and higher costs to lift profitability of key business

• $240 million, four-year program includes some $120 million in charges in 2005

• Approximately 1,300 jobs affected

• Company revises 2005 Power Technologies division and Group margin targets

• Group net income for Q2 expected to be significantly lower than Q1

Zurich, Switzerland, June 30, 2005 – ABB, the leading power and automation technology group, said today it is consolidating its global transformer business in response to overcapacity, increasing raw material costs and a regional shift in demand.

The consolidation program, aimed at significantly improving the profitability of the transformer business, is expected to run until the end of 2008 and cost approximately $240 million. Approximately $120 million will be recorded as a charge to earnings from continuing operations in 2005, most in the second quarter of 2005.

ABB said the focus is on increasing productivity and operational efficiencies. The consolidation will close a small number of plants in high-cost countries and cut about 1,300 jobs in the transformer business, or roughly ten percent of the total global workforce of 13,500 people.

The company is in discussions, or will begin talks shortly, with employee representatives to ensure the program is carried out in a socially responsible manner. The business today operates 57 plants in 28 countries.

ABB is the world’s leading producer of transformers used in substations, power plants, electrical locomotives, as well as systems to manage electricity grids and other applications. The business had revenues of approximately $2.5 billion in 2004, representing 26 percent of total Power Technologies division revenues.

ABB expects to increase the EBIT margin (earnings before interest and taxes as a share of revenues) in the transformers business from less than four percent in 2004 to more than eight percent by 2009.

“Overcapacity has been the biggest problem in the transformer industry in recent years, mainly the result of deregulation in the power sector,” said Fred Kindle, ABB President and CEO. “The situation has been made worse, however, by the unprecedented increase in raw material prices we’ve seen since 2004. As a result, we must take further steps now to improve

the profitability of this important business and to strengthen our leading market position.”

As a result of the significant additional charges for 2005 and higher raw material costs, ABB is issuing a revised 2005 EBIT margin target for the Power Technologies division in the range of 6.8-7.3 percent. As a consequence, the company is also lowering its 2005 Group EBIT margin target to 6.6-7.1 percent from 7.7 percent.

In the announcement of its first-quarter earnings in April 2005, ABB dropped the 2005 EBIT margin target of 10 percent for its Power Technologies division, first set in late 2002, saying rapidly increasing raw materials costs, mainly in the transformers business, and other operational challenges made achieving the target unrealistic.

The consolidation program announced today has no impact on the 2005 EBIT margin target for the Automation Technologies division, which remains unchanged at 10.7 percent. Progress remains on track towards the published targets in corporate cost reduction and performance of non-core operations.

Group net income in Q2 2005 will be significantly lower than in Q1. In addition to the impact of the above-described charges, negative effects to net income are expected from the “mark-to-market” accounting treatment of shares reserved for the asbestos trust, some losses in discontinued businesses, and non-asbestos related litigation charges.

ABB (www.abb.com) is a leader in power and automation technologies that enable utility and industry customers to improve performance while lowering environmental impact. The ABB Group of companies operates in more than 100 countries and employs about 102,000 people.
