Forward Looking Statements 2 This presentation contains forward-looking statements based upon Kintara’s current expectations. This communication contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements are identified by terminology such as “may,” “should,” “expects,” “plans,” “anticipates,” “could,” “intends,” “target,” “projects,” “contemplates,” “believes,” “estimates,” “predicts,” “potential” or “continue” or the negative of these terms or other similar words. These statements are only predictions. Kintara has based these forward-looking statements largely on its then-current expectations and projections about future events, as well as the beliefs and assumptions of management. Forward-looking statements are subject to a number of risks and uncertainties, many of which involve factors or circumstances that are beyond Kintara’s control, and actual results could differ materially from those stated or implied in forward-looking statements due to a number of factors, including but not limited to: (i) risks associated with the impact of the COVID-19 pandemic; (ii) risks and uncertainties relating to Kintara’s ability to develop, market and sell products based on its technology; the expected benefits and efficacy of Kintara’s products and technology; the availability of substantial additional funding for Kintara to continue its operations and to conduct research and development, clinical studies and future product commercialization; and, Kintara’s business, research, product development, regulatory approval, marketing and distribution plans and strategies, and (iii) those risks detailed in Kintara’s most recent Annual Report on Form 10-K and subsequent reports filed with the SEC, as well as other documents that may be filed by Kintara from time to time with the SEC. Accordingly, you should not rely upon forward-looking statements as predictions of future events. Kintara cannot assure you that the events and circumstances reflected in the forward-looking statements will be achieved or occur, and actual results could differ materially from those projected in the forward-looking statements. The forward-looking statements made in this communication relate only to events as of the date on which the statements are made. Except as required by applicable law or regulation, Kintara undertakes no obligation to update any forward-looking statement to reflect events or circumstances after the date on which the statement is made or to reflect the occurrence of unanticipated events. Investors should not assume that any lack of update to a previously issued “forward-looking statement” constitutes a reaffirmation of that statement.

VAL-083 Mechanism of Action 6 VAL-083’s unique mechanism of action creates inter-strand DNA cross-links at the N7 position of guanine, resulting in double-strand DNA breaks and cancer cell death via apoptosis Mechanism of VAL-083 via crosslinks at N7 of guanine Mechanism of temozolomide (TMZ) via alkylation at O6 of guanine 2 guanine bases on DNA VAL-083 VAL-083 – interstrand crosslink (ICL) temozolomide converts to active state (MTIC) at physiological pH guanine base on DNA alkylation of O6 guanine VAL-083’s unique DNA targeting mechanism circumvents MGMT-mediated chemoresistance and differentiates it from other therapies used in the treatment of GBM, including TMZ.

GCAR/GBM AGILE Advantages 10 Utilized non-profit funding to design and initiate GBM trial (1st patient enrolled: June 2019) Principals successful in platform and adaptive design paradigm per highly successful breast cancer trial (I-Spy): 10-year trial, 16 compounds tested, three received FDA accelerated approval Regulatory buy-in at highest level with strong FDA support Rapid study startup and patient enrollment Turn-key solution 31 sites currently enrolling Kintara arm: Includes one site in Canada Expanding into additional sites in the EU in the near future Shared control group: Contains costs and accelerates speed of study Has been enrolling for over two years Provides significant time and cost savings vs. multiple trials Avoids company scale up of fixed expenses for trial execution

GCAR: GBM AGILE Major Clinical Sites/Investigators 11 Principal Investigators of Kintara's arm of the GBM AGILE study: Dr. James Perry Professor of Neurology University of Toronto Sunnybrook Research Institute Dr. John de Groot Division Chief Neuro Oncology Division Department of Neurological Surgery University of California San Francisco With 40 sites enrolling, GBM AGILE includes Key Opinion Leaders and leading clinical sites: MD Anderson Cancer Center - Houston Memorial Sloan Kettering Center - New York Mayo Clinic Cancer Center - Jacksonville Henry Ford Health System - Detroit Mount Sinai - New York Dana Farber Cancer Institute - Boston Cleveland Clinic - Cleveland Duke University Medical Center - Durham “GBM AGILE is an innovative clinical trial approach that enables us to simultaneously and dynamically study the effects of multiple new drug candidates. With the inclusion of paxalisib and VAL-083 for newly-diagnosed unmethylated and recurrent GBM patients, as well as VAL-083 for the additional methylated GBM patient group, we are excited to offer all GBM patients access to these latest therapies.” - Dr. James Perry
