Melbourne, Australia, 2 February 2023: Genetic Technologies Limited (ASX: GTG; NASDAQ: GENE, “Company”, “GTG”), a global leader in guideline-driven genomics-based tests in health, wellness and serious diseases, lodges the attached Appendix 3Y - Change of Director’s Interest Notice - for Dr George Muchnicki.

In relation to the attached Appendix 3Y, we advise:

• Dr Muchnicki’s American Depositary Receipts were sold by the holding agent without his prior knowledge during a trading blackout period pending the release of the Company’s half-year financial report. Dr Muchnicki was unaware that a W-8BEN form, Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding and Reporting (Individuals), was required to be completed and returned to the holding agent resulting in the agent selling his shares.

• Dr Muchnicki remains the second largest individual shareholder in the company with the share sale occurring in one of his subsidiary entities.

• the Company’s directors are fully aware of its obligations under ASX Listing Rule 3.19A, requiring the Company to notify the ASX within 5 business days when there is a change in the notifiable interest of a director in the securities of GTG. Dr Muchnicki immediately notified the directors and company secretary of the sale of ADS when he became aware – 1 February 2023.

• as Dr Muchnicki was unaware that the sale of ADS was about to take place, he did not obtain the permission of the Chairman to trade as required by the Company’s Securities Trading Policy.

• the directors of GTG have agreed to review all holding arrangements of their securities held in GTG to ensure that this type of trade does not re-occur in the future.

• the Board of GTG can confirm that the Company is aware of its continuous disclosure obligations under listing rule 3.1.

Authorised for release by the board of directors of Genetic Technologies Limited.
