ABB completes delisting of shares from London Stock Exchange

Zurich, Switzerland, September 5, 2005 - ABB Ltd. said today it has completed
the process of delisting its shares from the London Stock Exchange.

ABB announced on August 4, 2005 it would delist its shares from the London and

2.50 each fully paid with ISIN number CH0012221716) had been canceled from
trading on the London Sock Exchange with immediate effect.

ABB expects to finalize the process of delisting its shares from the Frankfurt
Stock Exchange by the end of 2005. ABB shares will continue to be listed on the
SWX Swiss Exchange (traded on virt-x), the Stockholm Stock Exchange and New York
Stock Exchange.
