Interim Report January-March 2004

Interim Report January-March 2004

On April 19, 2004, Investor AB released its Net Asset Value Report for the first quarter of 2004.

Due to current accounting regulations, Investor is now required to report associated companies in accordance with the equity method in the consolidated income statement and balance sheet. As a consequence, Investor has had to wait for the interim reports of associated companies before it could prepare this formal Interim Report for the first three months of 2004, which we send to you now.

Our press releases can be accessed at www.investorab.com on the Internet.

Investor is the largest industrial holding company in the Nordic region. For almost a century, our business concept has been to build best-in-class companies in sectors where we have a strong knowledge and networking advantage.
