Voting Information
 
Registered ownership and beneficial ownership
 
If your Shares are registered in your name with our transfer agent and share registry, Computershare Limited, then you are considered the "registered owner" for those Shares. If you are the registered owner of your Shares then you have the right to vote your Shares by proxy or attorney, or to attend the AGM and vote via the Virtual Shareholder Meeting platform.



If your Shares are held through a bank, broker or other nominee, then you are the "beneficial owner" of the Shares, but you are not the "registered owner" of the Shares. As the beneficial owner of the Shares, you have the right to instruct your bank, broker or other nominee how to vote your Shares. In order to ensure your Shares are voted in the way you would like, you must provide voting instructions to your bank, broker or other nominee by the deadline provided by such bank, broker or other nominee.
 
If you are a beneficial owner and do not provide your bank, broker or other nominee with voting instructions, under the rules of various national and regional securities exchanges, the bank, broker or other nominee may generally vote on routine matters but cannot vote on non-routine matters (to the extent that there are non-routine matters). If the bank, broker or other nominee that holds your Shares votes on one or more matters, but does not receive instructions from you on how to vote your Shares on one or more non- routine matters (to the extent that there are non-routine matters), the bank, broker or other nominee will inform the Company that it does not have the authority to vote on such non-routine matters with respect to your Shares.
 
Entitlement to vote at the AGM
 
The Directors have determined that the persons eligible to vote at the AGM are those who are Shareholders of the Company at 5:00pm (ET) on 20 October 2022 and, in accordance with Regulation 7.11.37 of the Corporations Regulations 2001 (Cth) (Australia), those who are registered Shareholders of the Company at 7:30am (AEDT) on 12 December 2022, being 3.30pm (ET) on 11 December 2022. Accordingly, transfers registered after that time will be disregarded in determining entitlements to attend and vote at the AGM.
 
If you are not the registered owner of your Shares and you wish to vote at the AGM, please contact your bank, broker or other nominee for the procedures necessary to allow you to do so.
 
Voting by proxy
 
An eligible Shareholder can appoint a proxy or, where a Shareholder is entitled to two or more votes, the Shareholder may appoint two proxies. Where two proxies are appointed, a Shareholder may specify the number or proportion of votes to be exercised by each proxy appointed. If no number or proportion of votes is specified, each proxy appointed will be taken to exercise half of that Shareholder’s votes (disregarding fractions).
 
An appointed proxy need not themselves be a Shareholder.



A Proxy Card accompanies this Notice of Meeting. To be effective, your proxy (including the original or a certified copy of any power of attorney or other authority under which it is signed) must be received by the Company not less than 48 hours before the start of the AGM:

 
(i)
online: www.proxyvote.com;

 
(ii)
by mail: to Iris Energy Limited c/o Broadridge, 51 Mercedes Way, Edgewood, NY 11717; or
 
 
(iii)
by phone: by dialling 1-800-690-6903.
 
You can direct your proxy how to vote by following the instructions on the Proxy Card. Shareholders are encouraged to direct their proxy how to vote on the Resolution.
 
If you wish to direct your proxy to vote on the Resolution in the manner recommended by the Board, then your Proxy Card should be completed as follows.

Annual General Meeting
     
1     Appointment of Moore Australia as Auditor for the purposes of the Company's ASIC Audited Financial Statements (as defined in the Notice of Meeting).

Voting generally
 
On a poll at an AGM, every Shareholder present at the AGM has one vote for each fully paid Share held by the Shareholder (subject to the rights of holders of B Class Shares) and in respect of which the Shareholder is entitled to vote, and a proportional fraction of a vote for each partly paid Share held by the Shareholder and in respect of which the Shareholder is entitled to vote.
 
Where a person present at an AGM represents more than one Shareholder (whether personally, by proxy, attorney or, in the case of a corporate Shareholder, by corporate representative) the person is entitled to one vote on a poll at the AGM for each fully paid Share the person represents (subject to the rights of holders of B Class Shares), and a proportional fraction of a vote for each partly paid Share the person represents.



If a proxy is instructed to abstain from voting on a Resolution, they are directed not to vote on the Shareholder's behalf. On a poll, the Shares that are the subject of the proxy appointment will not be counted.
 
Any directed proxies that are not voted on a poll at an AGM by a Shareholder's appointed proxy will automatically default to the Chair, who is required to vote proxies as directed on a poll at the AGM.
 
If the Chair is appointed as your proxy (or is appointed your proxy by default), they can be directed how to vote by ticking the relevant boxes next to each item on the Proxy Card (i.e., 'for', 'against' or 'abstain').
 
The Chair intends to vote all undirected proxies IN FAVOUR of the Resolution.
 
Quorum
 
The AGM will only proceed if a quorum is present. If a quorum is not present within 30 minutes after the time appointed for the AGM, the AGM will be adjourned.
 
A quorum for the AGM will consist of at least 2 Shareholders present (which must include each holder of a B Class Share from time to time, to the extent that such holder is entitled to vote on one or more Resolutions at the AGM) and entitled to vote.
 
In determining whether a quorum is present, each individual attending as a corporate representative, proxy or attorney is to be counted, except that:

an individual attending in more than one capacity is to be counted only once; and

if a Shareholder has appointed more than one corporate representative, proxy or attorney, only one is to be counted.

Details of the above matter are set out in Section 2 of this Explanatory Statement.

1.
Financial Reports
 
Background
 
Under section 317 of the Corporations Act, the Financial Report, Directors' Report and Audit Report of the Company in respect of the 2022 financial year will be laid before the Meeting.
 
The Financial Report contains the consolidated financial statements of the Company and its controlled entities as required to be prepared and lodged with ASIC in accordance with section 319 of the Corporations Act. As such, the Financial Report and the consolidated financial statements included therein have been prepared and audited in accordance with the requirements of the Corporations Act.
 
The Company’s Financial Report is separate and distinct from the Company’s Annual Report on Form 20-F filed with the SEC on September 13, 2022, which includes the Company’s annual financial statements that have been prepared and audited in accordance with International Financial Reporting Standards as Issued by the International Accounting Standards Board. The Company’s Financial Report and the consolidated financial statements included therein are being presented to the Shareholders solely for the purposes of statutory compliance with the requirements of the Corporations Act.
 
This item does not require a formal resolution to be put to the AGM and so no vote will be held. However, Shareholders may ask questions on the matters contained in the reports. Shareholders will also be able to ask questions of the Company’s auditor, who will attend the AGM.



The reports are available on the Company's website, https://investors.irisenergy.co/financial-information/annual-reports.
 
Shareholders are being provided with a reasonable opportunity to ask questions on these statements and reports ahead of the Meeting. Shareholders may address written questions to the Chair about the management of the Company. All questions should be submitted to the Company in accordance with the instructions set out in the Notice of Meeting (under the heading "Participating at the virtual AGM").
 
The Chair of the Meeting will allow Shareholders to ask questions of Moore Australia or its representatives prior to the Meeting relevant to:

 
(i)
the conduct of the audit;

 
(ii)
the preparation and content of the Auditor’s Report;

 
(iii)
the accounting policies adopted by the Company in relation to the preparation of its ASIC Audited Financial Statements; and

 
(iv)
the independence of the auditor in relation to the conduct of the audit.

2.
Resolution 1 – Appointment of Moore Australia as auditor for purposes of the Corporations Act
 
On or about 27 October 2022, in accordance with section 327A of the Corporations Act, the Company appointed Moore Australia as auditor of the Company for purposes of the Corporations Act.
 
Following this appointment, in accordance with section 327A(2) of the Corporations Act, Moore Australia holds office as auditor until the Company's next annual general meeting, being the Meeting the subject of this Notice of Meeting.
 
In accordance with section 327B(1)(a) of the Corporations Act, the Company therefore now seeks Shareholder approval for the ongoing appointment of Moore Australia as auditor of the Company. In accordance with section 328B of the Corporations Act, a notice in writing nominating Moore Australia as auditor has been given to the Company by a Shareholder. A copy of the notice is included in this Notice of Meeting at Annexure A.
 
The appointment of Moore Australia will be by vote of Shareholders as an ordinary resolution. Moore Australia has provided to the Company, and has not withdrawn its written consent to act as auditor of the Company, in accordance with section 328A(1) of the Corporations Act.



The appointment of Moore Australia is solely for statutory reporting purposes under the Corporations Act. Such appointment is separate and distinct from the Company’s appointment of Armanino LLP, as the Company’s independent registered public accountant for all purposes other than the Corporations Act and the ASIC Audited Financial Statements. For further information regarding the Company’s appointment of Armanino LLP as its auditor for all purposes other than statutory reporting under the Corporations Act, please see the Company’s Annual Report on Form 20-F filed with the SEC on September 13, 2022, which report is available at www.sec.gov.
