Utilization of authorization within Investor AB to repurchase own shares to
hedge the company's long-term share-based remuneration program for employees and
synthetic shares as part of board remuneration

The 2008 Annual General Meeting of Investor AB approved the proposal to
authorize the company's Board of Directors to decide on the purchase of the
company's own shares for the purpose of hedging Investor's commitments and costs
in connection with its 2008 long-term share-based remuneration program for
employees and the issue of synthetic shares as part of board remuneration.
Investor hereby announces that the company's board has decided to utilize the
authorization for this purpose.
The shares will be purchased on the Stockholm Stock Exchange (Stockholmsbörsen)
before May 15, 2008 at a price within the registered share price interval on
each occasion.

Investor currently owns 1,400,000 of its own B-shares and intends to buy back an
additional 1,400,000 B-shares.
