Notice-and-Access
As permitted by the Canadian Securities Administrators and pursuant to exemptions obtained by the Corporation under the Canada Business Corporations Act (the “CBCA”), you are receiving this notice because the Corporation has elected to use the “notice-and-access” mechanism for delivery to Shareholders of this notice of annual meeting of Shareholders, the Circular and other proxy-related materials (collectively, the “Meeting Materials”), as well as the audited consolidated financial statements of the Corporation for the fiscal year ended March 31, 2026 and the independent auditor’s report thereon and the related management’s discussion and analysis (collectively, the “Financial Materials”). The Corporation has adopted notice-and-access for both registered and non-registered Shareholders. Notice-and-access is a set of rules that allow issuers to post electronic versions of proxy-related materials online, via SEDAR+ (www.sedarplus.ca) and one other website, rather than mailing paper copies of such materials to Shareholders. Under notice-and-access, Shareholders still receive proxy forms or voting instruction forms enabling them to vote at the Meeting. However, instead of paper copies of the Meeting Materials and the Financial Materials, Shareholders receive this notice which explains how they may access these documents online and how to request paper copies thereof. The use of notice-and-access directly benefits the Corporation by substantially reducing printing and mailing costs and is also more environmentally friendly as it reduces paper consumption.
You can access the Meeting Materials and the Financial Materials electronically by visiting www.d-box.com/en/investor-relations or under the Corporation’s profile on SEDAR+ at www.sedarplus.ca. Shareholders are reminded to review the Meeting Materials prior to voting.
In accordance with the Fighting Against Forced Labour and Child Labour in Supply Chains Act (Canada), the Corporation has made its Modern Slavery Report for its fiscal year ended March 31, 2026 (the “Modern Slavery Report”) available at www.d-box.com/en/investors/leadership-and-governance and under the Corporation’s profile on SEDAR+ at www.sedarplus.ca.
The Corporation will provide a paper copy of the Circular, the Modern Slavery Report or the Financial Materials to any Shareholder, free of charge, for a period of one year from the date the Circular is filed on SEDAR+ (www.sedarplus.ca). You may request a paper copy at any time before the Meeting by contacting Odyssey Trust Company (“Odyssey”), the Corporation’s transfer agent, via www.odysseytrust.com/ca-en/help or by phone at 1-888-290-1175 (toll-free within North America) or 1-587-885-0960 (direct from outside North America), in which case your request will be processed within three business days and the requested documents will be sent by first-class mail, courier or equivalent. Please take shipping time into consideration to ensure you receive the Circular before the Meeting. To ensure receipt of the paper copies in advance of the voting deadline and Meeting date, the Corporation estimates that your request must be received by no later than 5:00 p.m. (Eastern time) on September 11, 2026. Please note that you will not receive another form of proxy or voting instruction form, so please keep the one you received with this notice. After the Meeting, requests may be made by calling the same numbers, and each request will be processed within 10 calendar days.
The Meeting
The directors of the Corporation have, by resolution, fixed the close of business on August 7, 2026 as the record date for the determination of the Shareholders entitled to receive notice of the Meeting.
This year again, the Corporation will hold a virtual-only Meeting via live audio webcast. Shareholders will have an equal opportunity to participate in the Meeting online, regardless of geographic location, as well as to ask questions and vote on certain matters, but will not be able to attend the Meeting in person. Non-registered (or beneficial) Shareholders who have not duly appointed themselves as proxyholders will be able to participate in the Meeting as guests; however, guests will not be able to vote or ask questions at the Meeting. A summary of the information Shareholders and proxyholders will need to attend the Meeting online is provided in the Circular.
Shareholders who are unable to attend the Meeting are entitled to be represented by proxy and are requested to date, sign and return the enclosed form of proxy or voting instruction form in the envelope provided for that purpose or, alternatively, to vote through the online platform in accordance with the enclosed instructions. To be valid, a proxy must be duly completed and signed, and delivered to Odyssey (i) in person or by mail or courier to Proxy Department, 1100 – 67 Yonge Street, Toronto, Ontario, M5E 1J8, or (ii) via the internet at https://vote.odysseytrust.com. In order to be valid and acted upon at the Meeting, the form of proxy must be received no later than 10:00 a.m. (Eastern time) on September 21, 2026 or be deposited with the Corporate Secretary of the Corporation before the commencement of the Meeting or any adjournment thereof.
Online participation in the Meeting enables registered Shareholders to participate in the Meeting and ask questions in real time. Registered Shareholders can vote at the appropriate times by completing a ballot online during the Meeting. Registered Shareholders wishing to vote at the Meeting do not need to complete or return the form of proxy. However, even if a Shareholder wishes to participate in the Meeting, such Shareholder may vote their shares in advance; any such vote will be counted if the Shareholder later decides not to participate in the Meeting.
