GENETIC TECHNOLOGIES LIMITED A.B.N. 17 009 212 328 Quarterly Activities Report and Appendix 4C of the ASX Listing Rules for the quarter ended 30 June 2018

Quarterly Activities Report for the quarter ended 30 June 2018 HIGHLIGHTS Renewed focus on key initiatives, including R&D and global distribution Enhanced breast cancer test and new colon cancer test scheduled for launch in October Additional genetic screening products in development, including Prostate Cancer  Melanoma  Type 2 Diabetes Cardiovascular Disease Proposed demonstration projects under review with leading cancer and healthcare organisations in the US, Australia and Asia Distribution agreement for breast cancer screening tests into hospitals in China Collaboration with Project Shivom to support development of a new diabetes test for India Discussions underway with US telemedicine distributors Consumer-facing marketing launch to coincide with Breast Cancer Awareness month in October Melbourne, Australia, 31 July 2018: Genetic Technologies Limited (ASX: GTG; NASDAQ: GENE, “Company”, “GTG”), a diversified molecular diagnostics company embracing blockchain technologies across genomic testing platforms, is pleased to provide its Quarterly Activities Report for the period ending 30 June 2018, together with the attached Appendix 4C. New Product Development As announced on 16 July, the Company is on schedule to introduce an enhanced version of our breast cancer screening test. The new test will provide an opportunity for doctors to improve their ability to assess a patient’s breast cancer risk. While the BRCA test is often conducted to determine a woman’s genetic risk of developing hereditary breast cancer, it only addresses the 15% of women who have a strong family history of the disease. Our current product, BrevaGenplus addresses the 85% women who do not have a strong family history and are at risk of developing sporadic breast cancer. Taken together, the combination of BrevaGenplus testing and BRCA testing will provide comprehensive coverage for both hereditary and sporadic breast cancer. As previously reported, the Company is on track to begin the commercialisation process for a new colon cancer screening test in October. A scientific validation study has been completed, the results of which confirm previously evaluated modelling data. Test design and identification of relevant reporting requirements are in progress. In addition to the above, the Company has commenced development of a suite of genetic screening tests targeting both cancer and non-oncological diseases, including: Prostate Cancer Melanoma Type 2 Diabetes Cardiovascular Disease The new risk assessment tests represent a significant market opportunity. There are 8.2 million deaths from cancer per annum, 17.7 million deaths due to cardiovascular disease and 1.6 million deaths due to diabetes (World Health Organisation). Colorectal cancer represents 12.3% of all new cancers diagnosed in Australia in 2018. It is a leading cause of cancer death and disability in Australia and the USA.

Quarterly Activities Report for the quarter ended 30 June 2018 Research and Development Initiatives As announced on 1 May, GTG is part of a research team led by Professor John Hopper from The University of Melbourne’s Centre for Epidemiology and Biostatistics that was awarded a National Health and Medical Research Council (NHMRC) Partnership Grant. GTG’s Scientific Director, Dr Richard Allman is co-investigator on this award which aims to substantially improve breast cancer risk prediction as well as patient accessibility to genetic risk screening. As the sole commercial partner in this collaboration, GTG will have the right of first refusal to commercialise any new scientific discoveries. The Company has also initiated discussions with major cancer organisations in the US, Australia and Southeast Asia to develop pilot-scale programs for breast cancer genetic risk assessment screening. These organisations hold a long-term view to improve patient outcomes through the targeted application of healthcare resources. Unlike other tests on the market, GTG’s screening is clinically validated. As such, physicians in the US and other regions are authorised to recommend procedures and medications to address the needs of high-risk patients. This may include additional screening for individuals with an elevated risk of disease. Physicians can also rely on test results to clinically substantiate prescription of cancer preventative medication protocols. Demonstration projects with these organisations are targeted for regional rollout later this year. GTG continues to support the Shivom Project (Omix Ventures) as reported on 7 June. Shivom provides access to a large pool of data for research and has allowed us to expand our investigation into a risk assessment test for Type 2 Diabetes in India. Shivom’s blockchain platform is currently under development following their successful Initial Coin Offering that raised more than USD35M. GTG anticipates that the Shivom platform will be a distribution channel for existing and planned genetic risk screening tests. Global Distribution The Company is pursuing several strategic distribution partnerships to accelerate the adoption of our genetic screening tests in the US, Australia and Asia. GTG has appointed Swisstec Health Analytics to act as a non-exclusives distributor of our breast cancer screening tests into hospitals in Asia. Swisstec is a leading provider of medical imaging and healthcare IT solutions in Australia and Asia and have existing relationships with hospitals throughout the region. GTG is also in discussion with two major telemedicine providers in the US who can provide marketing, fulfilment and clinical support for customers as part of our consumer-initiated testing program in North America. In addition to our work with the Shivom Project, GTG continue to offer advisory support to blockchain platforms focussed on genetics, disease prevention and general health. As these projects present their platforms into new markets, we will work with them to offer genetic risk screening services as part of their overall offering to consumers. As part of our blockchain initiative, we are also working with Swisstec to develop a blockchain-enabled platform to address the retail market in Southeast Asia. Financial Snapshot Operational cash spend for the quarter was $1.3M and $6.4M for FY 2018, being $1.4M less than the previous corresponding full year period of $7.8M, representing an 18% reduction in annual cash spend. The Company’s modest cash receipts fell within the expected range during this time of strategic transition, as investment in R&D and development of distribution channels represent the major budgetary priorities for the Company. Lean management of administrative and other functional areas allow GTG to pursue commercial opportunities while maintaining a viable long-term financial strategy. As at 30 June 2018, the Company had $5.5M in cash. 2
