This presentation contains forward-looking statements within the meaning of the
Private Securities Litigation Reform Act of 1995. Such statements include, but are not limited to, statements concerning the End-of-Phase 2 meeting with the FDA to align on late-stage registration endpoints and study parameters, the launching
of RYZUMVI, the continued development of PS and LDP, our partnership with Viatris, the strength of our cash position, and the potential of APX3330 as an oral treatment for patients with non-proliferative diabetic retinopathy. These
forward-looking statements relate to us, our business prospects and our results of operations and are subject to certain risks and uncertainties posed by many factors and events that could cause our actual business, prospects and results of
operations to differ materially from those anticipated by such forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, those described under the heading “Risk Factors” included
in our Annual Report on Form 10-K. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this presentation. In some cases, you can identify forward-looking statements by the
following words: “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “ongoing,” “plan,” “potential,” “predict,” “project,” “should,” “will,” “would” or the negative of these terms or other comparable
terminology, although not all forward-looking statements contain these words. We undertake no obligation to revise any forward-looking statements in order to reflect events or circumstances that might subsequently arise. These forward-looking
statements are based upon Ocuphire’s current expectations and involve assumptions that may never materialize or may prove to be incorrect. Actual results and the timing of events could differ materially from those anticipated in such
forward-looking statements as a result of various risks and uncertainties, including, without limitation: the success and timing of regulatory submissions and pre-clinical and clinical trials, including enrollment and data readouts;
regulatory requirements or developments; changes to or unanticipated events in connection with clinical trial designs and regulatory pathways; delays or difficulties in the enrollment of patients in clinical trials; substantial competition
and rapid technological change; our development of sales and marketing infrastructure; future revenue losses and profitability; our relatively short operating history; changes in capital resource requirements; risks related to the inability
of Ocuphire to obtain sufficient additional capital to continue to advance its product candidates and its preclinical programs; domestic and worldwide legislative, regulatory, political and economic developments; employee misconduct; changes
in market opportunities and acceptance; reliance on third-parties; future, potential product liability and securities litigation; system failures, unplanned events, or cyber incidents; the substantial number of shares subject to potential
issuance associated with our Equity Line of Credit arrangement with LPC; risks that our partnership with Viatris, or our other licensing arrangements, may not facilitate the commercialization or market acceptance of Ocuphire’s product
candidates; future fluctuations in the market price of our common stock; the success and timing of commercialization of any of Ocuphire’s product candidates; and obtaining and maintaining Ocuphire’s intellectual property rights. The
foregoing review of important factors that could cause actual events to differ from expectations should not be construed as exhaustive. Readers are urged to carefully review and consider the various disclosures made by us in this presentation

Jeff Heier, MD Ophthalmic Consultants of Boston “If ZETA-1 results are
repeated in Phase 3, I would place virtually all of my diabetic patients on oral APX3330 and treat locally only as needed." "Ref-1 biology targets three pillars of diabetic eye disease: angiogenesis, inflammation, and oxidative stress. This
is promising in the quest to provide non-invasive, early options for patients." Peter Kaiser, MD Cleveland Clinic “I enjoy working with the team to develop an innovative protocol design to enroll the patients most likely to have
progressive disease while keeping the study practical to help enrollment." Arshad Khanani, MD Sierra Eye Associates Globally Recognized Retina Specialists Support APX3330 Development 25
