Dear Yulia,

Re: Petratherm Limited (PTR): Appendix 3Y – Change of Directors Interest Notice Query

I refer to your email dated 29 November 2022, regarding the Appendix 3Y lodged for Petratherm Director Simon O'Loughlin on 24 November 2022. An Appendix 3Y is attached to account for the discrepancy of 7,500 shares between the closing balance of the Appendix 3Y dated 15 February 2021 and the Appendix 3Y dated 24 November 2022. On behalf of Petratherm, I advise the following in response to your specific queries:

a) Clearly state that the missing Appendix 3Y should have been lodged between 15 February 2021 and 24 November 2022.

The attached Appendix 3Y should have been lodged before 10 June 2021.

b) Please explain why the Appendix 3Y was lodged late.

The attached Appendix 3Y was lodged late due to an inadvertent administrative oversight, when an off-market transfer of 7,500 shares took place between a family member of Mr O'Loughlin's to his Superannuation Fund.

c) What arrangements does PTR 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?

Agreements into which Petratherm has entered with its Directors require Directors to adhere to Petratherm's Continuous Disclosure Policy in relation to such items as share trading. They require Directors to notify the Company Secretary prior to trading in Petratherm shares in accordance with the company's Securities Trading Policy. Petratherm has also made arrangements with its share registry to be notified of changes in certain holdings, including Director's holdings.

Level 1, 169 Fullarton Road Dulwich SA 5065 T: +61 8 8133 5000

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

Petratherm considers that its arrangements are adequate and enforced. Petratherm considers this to be an isolated and inadvertent administrative oversight due to the out of the ordinary nature of the transfer of shares.

Yours sincerely,

Katelyn Adams Company Secretary

This ASX announcement has been approved by Petratherm's Company Secretary Katelyn Adams.
