Safe Harbor Statement Certain statements contained in this presentation regarding matters that are not historical facts are forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended, and the Private Securities Litigation Reform Act of 1995, known as the PSLRA. These include statements regarding management’s intentions, plans, beliefs, expectations or forecasts for the future, and, therefore, you are cautioned not to place undue reliance on them. No forward-looking statement can be guaranteed, and actual results may differ materially from those projected. NeuBase Therapeutics, Inc.

NeuBase uses words such as “anticipates,” “believes,” “plans,” “expects,” “projects,” “future ,” “intends,” “may,” “will,” “should,” “could,” “estimates,” “predicts,” “potential,” “continue,” “guidance,” the negative of these terms, and similar expressions to identify these forward-looking statements that are intended to be covered by the safe harbor provisions of the PSLRA. Such forward-looking statements are based on NeuBase’s expectations and involve risks and uncertainties; consequently, actual results may differ materially from those expressed or implied in the statements due to a number of factors, including, but not limited to, NeuBase’s plans to research, develop and commercialize any product candidates; the timing of initiation of any clinical trials; the risk that prior data will not be replicated in future studies; the timing of any investigational new drug application or new drug application; the clinical utility, potential benefits and market acceptance of any product candidates; NeuBase’s commercialization, marketing and manufacturing capabilities and strategy; global health conditions, including the impact of COVID-19; NeuBase’s ability to protect its intellectual property position; and the requirement for additional capital to continue to advance NeuBase’s product candidates, which may not be available on favorable terms or at all. New factors emerge from time to time and it is not possible for NeuBase to predict all such factors, nor can NeuBase assess the impact of each such factor on the business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements.

NEUBASE THERAPEUTICS, INC. 3 Stealth Editing™ Prime Editing Base Editing CRISPR/Cas Editing Stealth Editing™ in the Gene Editing Landscape 3

NEUBASE THERAPEUTICS, INC. 4 Stealth Editors™ - designed to fly under the radar of the immune system to effect high fidelity gene editing Immunogenicity from viral delivery systems and bacterial proteins presents a potential safety issue for patients receiving gene editing therapies 4

NEUBASE THERAPEUTICS, INC. 5 Why Stealth Editors™ Non-viral Delivery With a non-immunogenic system that can reach diverse tissues and cell types via systemic administration Pronounced In Vivo Effects Through the resolution of pathogenesis in a titratable and re-dosable fashion Broadly Applicable Can achieve gene disruption/repair across multiple species and industries Harnesses Cellular Mechanisms Through the utilization of DNA repair machinery that has been refined over millennia to deliver precise on-target edits with minimal off-target edits 5

NEUBASE THERAPEUTICS, INC. 6 In Vivo Editing Pipeline for Rare and Common Diseases Program Target Approach Discovery Preclinical Clinical Alpha-1 anti-trypsin disease SERPINA1 BCL11A Repair the PiZ mutation (E342K) of SERPINA1 to increase serum levels of alpha-1-antitrypsin to address emphysema and liver disease Multiple Multiple Multiple 6 Emerging Undisclosed blood diseases Various human diseases and agricultural applications are being evaluated to identify uniquely addressable pipeline programs • Stealth Editors™ are likely safer and have more durable solutions for in vivo applications • In vivo solutions are likely more cost-effective and safer than ex vivo solutions Undisclosed liver diseases Β-thalassemia Target selection in process Multi-base editing to disrupt the erythroid enhancer of BCL11A to induce hemoglobin switching only in red blood cells to correct the disease Target selection in process Ongoing target selection process: low competitive landscape, human genetic data, degree of unique ability to address causal mutation, availability of biomarker, short-term clinical endpoints, prevalence, unmet need, and ex vivo editing hits Liver Blood Prevalence ~33:100,0001 Prevalence ~1:100,0002 1 Brode SK, Ling SC, Chapman KR.
