2024 Annual Meeting of Shareholders

A virtual meeting is when participants gather online via a live webcast. The virtual platform allows shareholders to ask questions, vote and participate electronically in real time, as opposed to travelling to the meeting’s physical location.

Registered shareholders, duly appointed and registered proxyholders and guests may access the meeting being held via live webcast at https://web.lumiagm.com/453602059. Registered shareholders and duly appointed and registered proxyholders will be able to vote and ask questions during the meeting.

No, only the manner of engagement changes. A virtual meeting may help facilitate greater participation and engagement as it enables all shareholders and guests to participate in the meeting regardless of their location. We want this meeting to offer shareholders the same opportunities to participate as in-person meetings. Registered shareholders and duly appointed and registered proxyholders will be allowed to vote online and ask questions at the meeting.

Meeting materials are accessible on our website at www.atkinsrealis.com under “Investors”/“Investor’s Briefcase” or on SEDAR+ at www.sedarplus.com.

You will also be able to access the meeting materials by clicking on the document icon in the navigation bar at the top left side of your screen when logged in to the platform on the day of the event.

Registered shareholders can participate in the meeting by clicking “I have a login” and entering a username and password before the start of the meeting. The username is the control number located on the form of proxy or in the email notification you received, and the password is “atkinsrealis2024”.

Duly appointed and registered proxyholders can participate in the meeting by clicking “I have a login” and entering a username and password before the start of the meeting. The username is the control number provided by email and the password is “atkinsrealis2024”. If you have not appointed yourself to vote at the meeting or do not have a control number, you may log in as a guest by clicking on “I am a Guest” and complete the online form. Attending the meeting online as a guest will allow you to listen to the meeting but you will not be able to vote or submit questions.

Only registered shareholders and duly appointed and registered proxyholders who attend the meeting online will have the opportunity to ask questions during the meeting. We recommend that questions be submitted as soon as possible during the meeting so that they can be addressed in due course before a vote is held on each matter.

Once logged in to the platform, you will be able to ask a question at any time during the meeting, either in writing or via audio live during the webcast until the question period session is closed.

You can submit a question in writing by:

• Selecting the “messaging/questions” icon on the navigation bar on the top left side of your screen.
• Type your question into the text box at the bottom of the messaging screen and then click the send button.
• A confirmation will appear on the screen notifying you that your message has been received.

You can submit a question via live audio webcast by:

• Selecting the “messaging/questions” icon on the navigation bar on the top left side of your screen.
• Typing your telephone number and the reason you wish to be contacted by our operators into the text box at the bottom of the messaging screen and then click the send button.
• The virtual meeting operator will then dial you in the meeting.

General Questions Following the Formal Business of the Meeting

Following the formal business of the Meeting, management will give a presentation about the Company’s business. At the conclusion of this presentation, management or the Chair of the Board will address appropriate general questions from shareholders regarding the Company.

They should be succinct and cover only one topic per question. Questions from multiple shareholders on the same topic or that are otherwise related may be grouped, summarized and answered together. We do not intend to address any questions that are, among other things:

• irrelevant to the business of the Company or to the business of the meeting;
• related to material non-public information of the Company;
• related to personal grievances;
• derogatory references to individuals or that are otherwise in bad taste;
• repetitious statements already made by another shareholder;
• in furtherance of the shareholder’s personal or business interests; or
• out of order or not otherwise suitable for the conduct of the meeting as determined by the Chair of the meeting or Corporate Secretary in their reasonable judgment.

If there are any matters of individual concern to a shareholder and not of general concern to all shareholders, or if a question asked was not otherwise answered, such matters may be raised separately after the meeting by contacting Investor Relations at [email protected].

Registered shareholders and duly appointed and registered proxyholders will be able to vote.

Only registered shareholders and duly appointed and registered proxyholders will be able to vote. Once logged in to the meeting and the Chair declares the poll open, the “polling/voting” icon will appear on the navigation bar at the top left side of your screen and the meeting resolutions will be displayed. To vote, click on one of the voting options and your response will be highlighted.

The number of items you have voted on, or are yet to vote on, is displayed at the top of the screen. Votes may be changed up to the time the Chair closes the poll.

Note: Should you have voted in advance, no actions are required during the voting period. But if you are to click on one of the voting options, this will cancel out your previous vote.

No. The proxy voting methods available to shareholders from past years remain available. As in past years, we expect that the vast majority of votes will be cast in advance of the meeting by proxy through the various available methods, described in pages 9 and 10 of the Management Proxy Circular and Notice of Annual Meeting of Shareholders. Votes cast on the meeting day are an extremely small percentage of all votes cast.

Note: Should you wish to cancel your previous vote, you can always do so by casting your vote when the poll is open during the meeting and the meeting resolutions appear on your screen.
