Norsk Hydro : Appendix 9 - Guide for online participation of the AGM of Norsk Hydro ASA

Guide for digital participation at Norsk Hydro ASA's Annual General Meeting on May 10, 2022

Norsk Hydro ASA will hold its Annual General Meeting on May 10, 2022, from 10:00 to 12:15 CEST. The General Meeting will be held as a hybrid meeting where shareholders will have the opportunity to participate either in person or digitally via PC, telephone or tablet. Below is a guide for digital participation.

Please note that it will only be possible to cast votes digitally. This also applies to shareholders who participate in person. Therefore, it is important that you bring a telephone or tablet if you wish to attend the Annual General Meeting in person and cast your vote. Norsk Hydro ASA will not have the opportunity to lend such equipment to shareholders during the Annual General Meeting.

At the same time, we would like to point out that shareholders have the opportunity to cast their votes in advance or by proxy. Advance vote and proxy must be received by the Company within the deadline stated in the notice.

If you vote in advance or give a proxy, you may still log into the Annual General Meeting to follow and ask questions, but you will not have the opportunity to vote on the items on the agenda.

There will be a live webcast of the Annual General Meeting for shareholders who participate digitally, and they will have the opportunity to ask questions in writing and to cast votes for each item on the agenda. Secure identification of shareholders is done using unique reference numbers and PIN codes that will be allocated to each shareholder (or proxy if applicable) in Verdipapirsentralen (Euronext VPS) for Norsk Hydro ASA's Annual General Meeting.

Registration is not necessary for shareholders who wish to participate digitally, but shareholders must be logged in before the Annual General Meeting starts at 10:00 CEST on May 10.

Shareholders who are unable to find their Reference number and PIN code for login, or who have other technical questions are welcome to call DNB Bank Verdipapirservice at [phone] (between 08:00- 15:30 CEST) or send an email [e-mail]
