| • | The U.S. Food and Drug Administration (FDA) granted Regenerative Medicine Advanced Therapy (RMAT) designation for OPGx-LCA5, for the treatment of Leber Congenital Amaurosis (LCA) due to genetic
              variations in the LCA5 gene, signifying the program’s potential to address a serious condition and providing a pathway for accelerated development and review. | 
| • | Twelve-month clinical data from adult participants in the Phase 1/2 trial demonstrated sustained improvements in visual function, including visual acuity gains and improved mobility testing scores.
              This data was presented at the Association for Research in Vision and Ophthalmology (ARVO) Annual Meeting in May. | 
| • | Initial pediatric data at one-month post-treatment showed vision improvement with no drug-related adverse events; three-month pediatric data is expected to be reported in Q3 2025. | 
| • | Preclinical data presented at the American Ophthalmological Society (AOS) in May demonstrated restoration of the retinal pigment epithelium-photoreceptor interface in a canine model of BEST1 using
              AAV-mediated gene delivery. | 
| • | Investigational New Drug (IND) submission and Phase 1/2 trial initiation remain on track for the second half of 2025. | 
| • | Partnership with the Global RDH12 Alliance provides up to $1.6 million in non-dilutive funding to accelerate development of OPGx-RDH12 for Leber congenital amaurosis (RDH12-LCA). | 
| • | Non-dilutive funding up to $2 million received from the Retinal Degeneration Fund to advance OPGx-MERTK, targeting retinitis pigmentosa caused by MERTK mutations. | 
| • | Preclinical OPGx-MERTK data presented at the American Society of Gene & Cell Therapy (ASGCT) in May showed preservation
              of retinal function in animal models. | 
| • | VEGA-3 Phase 3 trial met its primary and multiple secondary endpoints in presbyopia, with 27.2% of treated patients achieving a ≥15-letter gain in near visual acuity (vs. 11.5% on placebo,
              p<0.0001) and favorable participant reported outcomes and safety profile. | 
| • | LYNX-2 Phase 3 trial met its primary and multiple secondary endpoints in keratorefractive patients with night vision disturbances. Patients showed statistically significant gains in mesopic low
              contrast vision and improvements in night-driving related symptoms. | 
| • | sNDA submission for presbyopia indication planned for the second half of 2025. | 
| • | LYNX-3 Phase 3 trial expected to initiate enrollment in the second half of 2025 targeting reduced low light vision and nighttime visual disturbances. | 
| • | Virtual reality-guided functional testing to support meaningful clinical endpoints in IRD trials was presented at the Retinal Imaging Biomarkers Summit. | 
| • | Report three-month pediatric data from OPGx-LCA5 Phase 1/2 trial in Q3 2025. | 
| • | Initiate enrollment in Phase 1/2 trial for OPGx-BEST1 in H2 2025. | 
| • | Submit Phentolamine sNDA for presbyopia in H2 2025. | 
| • | Initiate enrollment in Phentolamine LYNX-3 Phase 3 trial in H2 2025. |
