 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 success and timing of planned regulatory filings and approvals, pre-commercial activities, commercialization strategy and timelines, business strategy, product labels, cash runway, scalability, future clinical trials in presbyopia (P), dim light/night vision disturbance (DLD) and diabetic retinopathy (DR) / diabetic macular edema (DME), including the potential for Phentolamine Ophthalmic Solution (POS) to be a “best in class” presbyopia drop, and timing of planned future clinical trials for APX3330, APX2009 and APX2014, the advancement to Phase 3 registration path for APX3330, FDA agreement on Special Protocol Assessment, the success and timing of planned regulatory filings, business strategy, cash runway, scalability, the potential for APX3330 to be the most advanced and the first line of therapy for DR patients, and the potential market opportunity for and the ability of APX3330 to slow DR progression. These forward-looking statements are based upon the Company’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: (i) the success, costs, and timing of regulatory submissions and pre-clinical and clinical trials, including enrollment and data readouts; (ii) regulatory requirements or developments; (iii) changes to clinical trial designs and regulatory pathways; (iv) changes in capital resource requirements; (v) risks related to the inability of Ocuphire to obtain sufficient additional capital to continue to advance its product candidates and its preclinical programs; (vi) legislative, regulatory, political and economic developments, (vii) changes in market opportunities, (viii) risks that the partnership with Viatris may not facilitate the commercialization or market acceptance of Ocuphire’s product candidates; (ix) the success and timing of commercialization of any of Ocuphire’s product candidates, including the scalability of Ocuphire’s product candidates and (x) the maintenance of 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 and should be read in conjunction with statements that are included herein and elsewhere, including the risk factors detailed in documents that have been and may be filed by the Company from time to time with the SEC.

Diabetes results from defects in the body's ability to produce and/or use insulin  Diabetic retinopathy (DR) occurs when fluctuations or instability in blood glucose levels damages blood vessels in the retina   Type 1 diabetes (T1D): The body produces very little or no insulin, which means that patients need daily insulin injections to maintain blood glucose levels  Type 2 diabetes (T2D): The most common form of diabetes - either the body does not produce enough insulin, or resists insulin  Normal Retina  Diabetic Retina

 APX3330 Summary  Successful EOP2 FDA meeting completed in October 2023; agreement that a 3-step change on the binocular person scale is an approvable registration endpoint  Submit Special Protocol Assessment (SPA)   Advance APX3330 into Phase 3 program with long-term exposure (up to 2 years)  APX3330 Milestones  To have a clinically meaningful impact on slowing or preventing progression to reduce likelihood of vision loss in diabetic retinopathy patients  Our Goal for Patients  30 
 

 DR is one of the largest markets in retina with 10M patients in US and over 100M worldwide  Majority of the NPDR patients are not candidates for approved biologics treatments and are left untreated  APX3330 first-in-class oral drug with unique MOA that inhibits Ref-1 which reduces VEGF and inflammatory cytokines to normal physiological levels  Prevention of worsening is a clinically meaningful potential registration endpoint   APX3330 demonstrated favorable safety and tolerability in diabetic patients  Successful EOP2 meeting with the FDA and a Special Protocol Assessment (SPA) to be submitted  APX3330 has the potential to be an early, non-invasive preventative treatment for the 8 million NPDR patients with the potential to treat other organs affected by diabetes (e.g., kidney disease, peripheral neuropathy)  Broad prescriber base including general ophthalmology, optometry and primary care due to favorable safety  DR and APX3330 Key Takeaways
