#### Opus Genetics Highlights Five Gene Therapy Programs Targeting
**Significant Unmet Need in Patients with Inherited Retinal Diseases**<br>

*Rapidly Advancing Five IRD Programs with Four Clinical Data Readouts Expected in 2027*

*RDH12, MERTK and RHO Programs Expected to Enter Clinical Testing over the Next 12 to 18 Months*

*Cash Runway into 2029 Expected to Fund Multiple Clinical Inflection Points, Potential Product Approvals and Opportunities for Priority Review Vouchers*

*IRD Prevalence Across Select Global Markets Provides a Significant Commercial Opportunity Across Opus Genetics' Pipeline*

RESEARCH TRIANGLE PARK, N.C. – June 16, 2026 - <u>Opus Genetics, Inc.</u> (Nasdaq: IRD) (the "Company" or "Opus Genetics"), a clinical-stage biopharmaceutical company developing gene therapies to restore vision and prevent blindness in patients with inherited retinal diseases (IRDs), hosted a Research and Development (R&D) Science Forum where management and leading IRD experts highlighted the Company's expanding gene therapy pipeline for severe retinal diseases. The event highlighted three new programs entering clinical testing, recent LCA5 and BEST1 clinical data, the global IRD market opportunity, and clinical development and execution strategies.

"As featured in our R&D Science Forum, our validated scientific approach and early clinical success provides strong momentum as we expand into our new set of promising programs," said George Magrath, M.D., Chief Executive Officer of Opus Genetics. "We have first-mover advantage across multiple indications, supported by broad intellectual property protection, rare-disease regulatory pathways that may offer flexibility and accelerated approval, and the potential for Orphan Drug exclusivity and Priority Review Vouchers. Our approach emphasizes streamlined timelines, capital-efficient development, a premier collection of scientific advisors, and an experienced leadership team capable of executing multiple clinical programs in parallel."

#### Gene Therapy Program Highlights

#### OPGx-RDH12
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• RDH12 mutations cause a severe form of Leber congenital amaurosis (LCA), which leads to early, rapid vision loss in infancy or childhood, often resulting in legal blindness before the third decade of life.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Estimated global prevalence is 30,900 patients, including 2,500 patients in the U.S. and 17,500 patients in the Middle East / North Africa.\*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• OPGx-RDH12 is designed to restore a key component of the visual cycle.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In preclinical studies, OPGx-RDH12 delivered a functional RDH12 enzyme in vivo and restored structure and function in a small animal model.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• This program is expected to initiate clinical testing in the U.S. in the fourth quarter of 2026. Funding is supported by the RDH12 Alliance.

#### OPGx-MERTK
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• MERTK mutations cause a severe form of autosomal recessive retinitis pigmentosa, which has an early-onset (childhood or adolescence) and results in rapid vision loss.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Estimated global prevalence is 21,960 patients, including 2,600 patients in the U.S. and 14,300 patients in the Middle East / North Africa.\*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• OPGx-MERTK is designed to restore critical retinal pigment epithelium metabolic functions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In preclinical studies, OPGx-MERTK provided evidence of retinal preservation of structure/ function and preserved outer nuclear layer thickness in a small animal model of retinal degeneration.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• This program is expected to initiate clinical testing at the Cleveland Clinic Abu Dhabi in the first quarter of 2027. Funding is supported by a consortium led by Abu Dhabi's Healthcare Research and Innovation Fund.

#### OPGx-RHO
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• RHO mutations cause autosomal-dominant retinitis pigmentosa, a highly variable, often slowly progressive rod-cone dystrophy characterized by misfolded or dysfunctional rhodopsin that drives photoreceptor stress and progressive peripheral field loss followed by central vision decline.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Estimated global prevalence is 30,200 patients, including 8,800 patients in the U.S.\*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• OPGx-RHO is designed to "silence and replace" in autosomal dominant RHO.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In preclinical studies, OPGx-MERTK maintained rod morphology in the retinas in two large animal models.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• This program is expected to initiate clinical testing globally in the second half of 2027.

------

#### OPGx-LCA5
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• LCA5 mutations cause a very early onset, severe disease typically presenting in infancy or early childhood.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Estimated global prevalence is 3,240 patients, including 170 patients in the U.S.\*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• OPGx-LCA5 is designed to restore the lack of functioning lebercilin, a key protein of the visual cycle, which severely impairs photoreceptor function.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In the ongoing Phase 1/2 clinical trial, visual acuity was improved and maintained in the adult cohort over 24 months and improved in the pediatric cohort over 6 months. In addition, the full-field stimulus test (FST) demonstrated durable vision improvement and microperimetry data provided evidence of increased sensitivity and movement of fixation toward the fovea.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Recruitment is ongoing in the run-in period for the pivotal Phase 3 trial. In parallel, the clinical and commercial batch of drug product is being manufactured. Dosing with OPGx-LCA5 is expected to start in the fourth quarter of 2026.

#### OPGx-BEST1
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• BEST1 mutations disrupt cellular ion and fluid homeostasis resulting in electrophysiological abnormalities, RPE dysfunction, and retinal degeneration, with a range of onset from childhood to adulthood and a slow rate of progression.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Estimated global prevalence is 21,800 patients, including 8,400 patients in the U.S. comprised of approximately 8,000 best vitelliform macular dystrophy (BVMD) and approximately 400 autosomal recessive bestrophinopathy (ARB).\*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• OPGx-BEST1 is designed to target retinal pigment epithelium (RPE) cells and restore bestrophin function.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In the ongoing Phase 1/2 clinical trial, three BVMD and two ARB participants were enrolled in the first cohort, with dosing completed in May 2026.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Three-month topline data from Cohort 1 is expected in September 2026.

#### Commercial Market Opportunity
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• IRD patient prevalence across select global markets provides significant commercial market opportunity across Opus' pipeline.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• IRD prevalence may be higher than current estimates in some mutations. For example, patients may not undergo genetic testing when clinicians diagnose BEST1 disease based on the presence of a characteristic vitelliform ("egg-yolk") lesion beneath the macula.
