Where to get a copy of the management information circular and our other documents

We use notice and access to deliver meeting materials (this notice and the management information circular) to registered and beneficial holders of our shares. Notice and access is a set of rules developed by the Canadian Securities Administrators that allows companies to post meeting materials online, reducing paper and mailing costs.

If you have given us instructions to send you printed documents, your management information circular is attached to this notice, and we have mailed you a copy of our 2025 consolidated financial statements and related management's discussion and analysis.

Beneficial Shareholders are asked to consider signing up for Electronic Delivery ("E-delivery") of the Meeting materials. E-delivery has become a convenient way to make distribution of materials more efficient and is an environmentally responsible alternative by eliminating the use of printed paper and the carbon footprint of the associated mail delivery process. Signing up is quick and easy, go to www.proxyvote.com and sign in with your control number, vote for the resolutions at the meeting and following your vote confirmation, you will be able to select the electronic delivery box and provide an email address. Having registered for electronic delivery, going forward you will receive your Meeting materials by email and will be able to vote on your device by simply following a link in the email sent by your financial intermediary, provided your intermediary supports this service.

All other shareholders can download these documents after April 6, 2026:

• from our website: www.superiorplus.com
• from our profile on SEDAR+: www.sedarplus.ca

Prior to the meeting, if you prefer to have a printed copy of these documents, contact our head office right away and we'll send you one free of charge within three business days after receiving such request.
