AGENDA

ITEM 1: DIRECTORS REPORT, AUDITOR’S REPORT AND FINANCIAL STATEMENTS

“To receive and to consider the Annual Financial Report of Abacus Storage King and its controlled entities for the financial year ended 30 June 2025 together with the declaration of the Directors, the Directors’ Report, the Remuneration Report and the Auditor’s Report for that financial year.”

Note: This item of ordinary business is for discussion only and is not a resolution.

Pursuant to the Corporations Act, Securityholders will be given a reasonable opportunity at the Meetings to ask questions about, or make comments in relation to, each of the aforementioned reports during consideration of these items.

ITEM 2: RESOLUTIONS

Resolution 1 – Adoption of Remuneration Report

To consider and, if thought fit, to pass the following resolution as an Ordinary Resolution of the Company:

“That, for the purpose of Section 250R(2) of the Corporations Act and for all other purposes, approval is given for the adoption of the Remuneration Report as contained in Abacus Storage King’s Annual Financial Report for the financial year ended 30 June 2025.”

Note: The vote on this Resolution is advisory only and does not bind the Directors or the Company.

: Voting Prohibition Statement In accordance with the Corporations Act, a vote must not be cast (in any capacity) on Resolution 1 by or on behalf of a member of Abacus Storage King’s key management personnel ( KM P), whose remuneration details are included in the Remuneration Report, or any of that person’s Closely Related Parties (such as close family members and any controlled companies of those persons) (collectively referred to as Restricted Voter). However, such a person described above may cast a vote on Resolution 1 if:

• it is cast by a person as a proxy appointed in writing that specifies how the proxy is to vote on Resolution 1; and

• it is not cast on behalf of a Restricted Voter.

If you appoint the person chairing the Meetings (Chair) as a proxy and the Proxy Form does not specify the way the proxy is to vote on the resolution and you are not a Restricted Voter, by submitting the Proxy Form you authorise the Chair to exercise the proxy even though Resolution 1 is connected directly or indirectly with the remuneration of a KMP, and you will be taken to have directed the Chair to vote in accordance with his or her stated intention to

==> picture [131 x 76] intentionally omitted <==

2

vote in favour of Resolution 1. If you do not want your vote exercised in favour of Resolution 1, you should direct the person chairing the Meetings to vote “against”, or to abstain from voting on, this Resolution.

In addition, under the Corporations Act, a vote must not be cast on Resolution 1 by a member of Abacus Storage King’s KMP, or a Closely Related Party of a KMP, acting as proxy, if their appointment does not specify the way the proxy is to vote on the resolution. However, this voting exclusion does not apply if the KMP is the Chair of the Meeting acting as proxy and their appointment expressly authorises the Chair of the Meeting to exercise the proxy even though the resolution is connected directly or indirectly with the remuneration of a member of the KMP.

Resolution 2 – Re-election of John O’Sullivan as Director

To consider and, if thought fit, to pass the following resolution as an Ordinary Resolution of the Company:

“That John O’Sullivan, who retires in accordance with the Constitutions and Listing Rules and, being eligible, be re-elected as a director of Abacus Storage Operations Limited.”

Resolution 3 – Re-election of Karen Robbins as Director

IMPORTANT VOTING INFORMATION

Your vote is important

The business of the Annual General Meetings affects your security holding and your vote is important.

Voting in person

To vote in person, attend the Annual General Meetings on the date and at the place set out above.

Voting by proxy

If you are unable to attend the Meetings, you are encouraged to appoint a proxy to attend and vote on your behalf.

A securityholder entitled to attend and vote at the Meetings is entitled to appoint a proxy. A securityholder entitled to cast two or more votes may appoint two proxies and may specify the proportion or the number of votes each proxy is appointed to exercise. A proxy need not be a securityholder of Abacus Storage King. A Proxy Form is provided with this Notice of Meetings.

You can direct your proxy how to vote by following the instructions on the Proxy Form. Securityholders are encouraged to direct their proxy how to vote on each item of business.

Any directed proxies that are not voted on a poll at the Meetings by a securityholder’s appointed proxy will automatically default to the Chair, who is required to vote proxies as directed on a poll.

If you intend to appoint the Chair as your proxy (or if the Chair becomes your proxy by default), you can direct the Chair how to vote by marking one of the voting boxes for the relevant resolution on the Proxy Form (for example to vote ‘for’, ‘against’ or ‘abstain’ from voting). Alternatively, if the Chair is or becomes your proxy and you do not mark any of the boxes opposite a resolution, the Chair may vote as he/she sees fit. Please note that by submitting the Proxy Form without voting instructions, you will be giving the Chair your express authority to vote your proxy as he/she decides on remuneration related resolutions (being Resolution 1), even though the resolution is connected directly or indirectly with the remuneration of a member of the KMP of Abacus Storage King.

The Chair of the Meetings intends to vote all undirected proxies held by the Chair in favour of each Resolution.

Completion of a Proxy Form will not prevent individual securityholders from attending the Meetings in person if they wish. Where a securityholder completes and lodges a valid Proxy Form and then the securityholder attends the Meetings in person, if the member votes on a resolution, their proxy is not entitled to vote, and must not vote, on that resolution.

If a securityholder appoints a body corporate as a proxy, that body corporate will need to ensure that it:

• appoints an individual as its corporate representative to exercise its powers at the meetings, in accordance with section 250D of the Corporations Act; or

• provides satisfactory evidence of the appointment of its corporate representative prior to commencement of the Meetings unless this has previously been provided to the Share Registry.

Corporate securityholders should comply with the execution requirements set out on the Proxy Form or otherwise comply with the provisions of section 127 of the Corporations Act.

==> picture [131 x 76] intentionally omitted <==

Your Proxy instruction must be received not later than 48 hours before the commencement of the Meetings, which is 11:00am (AEDT) on Sunday, 9 November 2025.
