Mr Stuart Roberts ASX Limited Level 4, 20 Bridge St Sydney NSW 2000 e. ListingsComplianceSydney@asx.com.au

Dear Mr Roberts

Macquarie Technology Group Limited (MAQ) - Appendix 3Y Lodged on 15 May 2024 - Change of Director’s Interest Notice Query

Thank you for your letter on this matter dated 20 May 2024. MAQ provides the following information and responses to the matters raised (using the same capitalised terms as defined in your letter).

On 6 May 2024, a disposal of 350,000 shares by Claiward Pty Ltd, which is jointly owned by executive directors David Tudehope and Aiden Tudehope, occurred, and the following notices were subsequently filed:

Date7 May 202415 May 202415 May 2024	Party	Notice	Detailsprovided
	MAQ on behalf ofClaiward Pty Ltd	Form 604: Change ofSubstantial Holding	10,651,123:Claiward 10,650,990David Tudehope 133
	MAQ on behalf ofDavid Tudehope	Appendix 3Y	10,651,123
	MAQ on behalf ofAidan Tudehope	Appendix 3Y	10,650,990

MAQ acknowledges the late notification of the above two Appendix 3Y Notices in respect to such changes. The Notices should have been lodged by 13 May 2024, as opposed to 15 May 2024, and we acknowledge that lodging such Notices on time is the Company's responsibility.

Responses to Request for Information

1. Reason for Delay - The delay arose because of confusion over who was preparing the Notice forms. On prior occasions Directors have arranged for their agents to prepare and supply such forms to the Company for uploading with the ASX, as had occurred with the Form 604 eight days prior. The issue was exacerbated given the handover to the new Company Secretary occurring during the same period. We note that the details of the changes were all contained in the Form 604, and it was the duplication in Appendix 3Y of the same information that had already been lodged on 7 May 2024, which was late.

2. Arrangements with Directors under Listing Rule 3.19B to ensure compliance with disclosure obligations under Listing Rule 3.19A - We confirm that the Company has appropriate arrangements in place, including in its agreements and enforceable policies that apply to Directors, to ensure compliance with Listing Rule 3.19A.

1. Additional steps to ensure compliance with Listing Rule 3.19B - As part of the process to change MAQ's Company Secretary that took place on 15 May 2024, arrangements with Directors have been reviewed and going forward the Company will prepare the Appendix 3Y, and the Directors agent the form 604, which should avoid this issue arising again in the future.

Yours sincerely,

Justin Forsell

Dear Mr Forsell

Macquarie Technology Group Limited (‘MAQ’): Appendix 3Ys – Change of Director’s Interest Notice Query

1. MAQ’s Appendix 3Y Notices lodged on the ASX Market Announcements Platform (‘MAP’) on 15 May 2024 for David and Aidan Tudehope (the ‘Notices’);

2. Listing Rule 3.19A which requires an entity to tell ASX the following:

3.19A.2 A change to a notifiable interest of a director of the entity (or in the case of a trust, a director of the responsible entity of the trust) including whether the change occurred during a closed period where prior written clearance was required and, if so, whether prior written clearance was provided. The entity must complete Appendix 3Y and give it to ASX no more than 5 business days after the change occurs.

1. Listing rule 3.19B which states that:

‘An entity must make such arrangements as are necessary with a director of the entity (or in the case of a trust, a director of the responsible entity of the trust) to ensure that the director discloses to the entity all the information required by the entity to give ASX completed Appendices 3X, 3Y and 3Z within the time period allowed by listing rule 3.19.A. The entity must enforce the arrangements with the director.’

The Notices indicates that a change in the respective notifiable interests of David and Aidan Tudehope occurred on 6 May 2024. It appears that the Notices should have been lodged with ASX by 13 May 2024. Consequently, MAQ may have breached Listing Rules 3.19A and/or 3.19B.

Request for Information

Under Listing Rule 18.7, we ask that you answer each of the following questions having regard to Listing Rules 3.19A and 3.19B and Guidance Note 22: Director Disclosure of Interests and Transactions in Securities - Obligations of Listed Entities .

1. Please explain why the Appendix 3Y Notices were lodged late.

2. What arrangements does MAQ have in place under Listing Rule 3.19B with its directors to ensure that it is able to meet its disclosure obligations under Listing Rule 3.19A?

3. If the current arrangements are inadequate or not being enforced, what additional steps does MAQ intend to take to ensure compliance with Listing Rule 3.19B?

When and where to send your response

This request is made under Listing Rule 18.7. Your response is required as soon as reasonably possible and, in any event, by no later than 9:00 AM AEST Thursday, 23 May 2024 . You should note that if the information

requested by this letter is information required to be given to ASX under Listing Rule 3.1 and it does not fall within the exceptions mentioned in Listing Rule 3.1A, MAQ’s obligation is to disclose the information ‘immediately’. This may require the information to be disclosed before the deadline set out in the previous paragraph and may require MAQ to request a trading halt immediately.

Your response should be sent to me by e-mail at ListingsComplianceSydney@asx.com.au . It should not be sent directly to the ASX Market Announcements Office. This is to allow me to review your response to confirm that it is in a form appropriate for release to the market, before it is published on the ASX Market Announcements Platform.

We require the request for a trading halt to be in writing. The trading halt cannot extend past the commencement of normal trading on the second day after the day on which it is granted.
