Announcement of intention of new issue and early redemption

The Issuer has today announced that it is considering issuing a new series of notes, subject to market conditions, under its EUR 5,000,000,000 Debt Issuance Programme. Subject to the successful pricing and settlement of those notes, the Issuer intends to redeem its outstanding Notes in whole pursuant to Condition 6(d) (the "Call Option") of the terms and conditions of the Notes (the "Conditions") set out in Part C of Schedule 2 to the trust deed dated 15 December 2010 (the "Trust Deed") relating to the Notes. The Issuer intends to announce further details of such redemption on (or shortly after) settlement of the new series of notes.

Part of the proceeds from the new issue is intended to be used for purchasing the Notes. The rationale of the early redemption and the new issue is thus to proactively manage upcoming debt repayments and to extend the average debt maturity profile of Investor AB.

This announcement is not a formal notice of redemption to the Noteholders pursuant to the Conditions. The Issuer intends to publish such formal notice of redemption in due course. If the Issuer does not issue the new series of notes for any reason, it does not intend to exercise the Call Option, at this time.

Unless otherwise defined herein, defined terms used have the meanings given to them in the Trust Deed.

For the purposes of MAR and Article 2 of Commission Implementing Regulation (EU) 2016/1055, this announcement is made by Magnus Dalhammar, Head of Investor Relations at Investor AB.
