Sozinibercept, a Proprietary VEGF-C/D “Trap” Inhibitor, Has the Potential to Address the Limitations of Anti-VEGF-A Therapies The Problem The Solution Wet AMD is a multi-factorial disease. Treatment with VEGF-A inhibitors upregulates VEGF-C/D, driving angiogenesis and vascular permeability. When used in combination with any VEGF-A inhibitor, sozinibercept completely blocks VEGFR-2 and VEGFR-3 signaling. 1 Faricimab also has inhibitory effect on Ang-2. a Bevacizumab is used ’off-label’ for the treatment of neovascular (wet) AMD Faricimab (Vabysmo®)1 SOZINIBERCEPT

The Phase 3 clinical trial masked data are incomplete and subject to additional analysis once unmasked. There is no assurance that standard of care monotherapy in our Phase 3 clinical trials will yield similar results to our prior clinical trials or previously published clinical trials with anti-VEGF-A monotherapies. As a result, there can be no assurance that topline results for sozinibercept from the Phase 3 clinical trial, if completed, will be consistent with results from masked data available to date. Pooled safety analysis of 399 patients for completed sozinibercept trials Data Monitoring Committee (“DMC”) regularly reviews data from ongoing Phase 3 COAST and ShORe studies Safety data from our completed sozinibercept trials show sozinibercept combination therapy has a safety and tolerability profile comparable to standard of care anti-VEGF-A monotherapy.

Phase 3 Wet AMD Trials COAST and ShORe Are Well Advanced Topline Data Anticipated for COAST in Early 2Q CY 2025 and ShORe in Mid-CY2025 Design Multi-center, double-masked, randomized (1:1:1), sham control Treatment naïve wet AMD patients Regulatory Quality ~90% power, 5% type I error rate Sample Size COAST n=998; ShORe n=986 Comparators 2 mg Eylea® q8w (COAST) & 0.5 mg Lucentis® q4w (ShORe)
Phase 3 Primary and Secondary Endpoints Primary Efficacy Endpoint at Week 52 to Support BLA Submission Primary Endpoint Key Secondary Endpoints (Baseline to Week 52) Mean change from baseline in BCVA at week 52 Proportion of participants gaining ≥15 letters Proportion of participants gaining ≥10 letters Change in choroidal neovascularization area Proportion of participants with absence of both sub-retinal fluid and intra-retinal cysts

Please refer to the description of the DFA included in the Company’s Form 6-K filed with the SEC on August 15, 2022 and the DFA filed as Exhibit 4.14 to the Company’s Annual Report on Form 20-F filed with the SEC on September 29, 2022 for more information. Note: Additional funding will be required to reach commercialization of sozinibercept and to meet obligations under the Development Funding Agreement ("DFA"). As a result of obligations under the DFA and applicable law regarding liquidity, the Company expects to raise or obtain additional capital in one or more transactions, earlier than 3Q CY 2025 or anticipated topline data readout dates.
Addressing unmet medical need of improved efficacy in large wet AMD patient population in a potential ~$15B market 1 Sozinibercept Will Not Compete Head-to-Head with Anti-VEGF-A Differentiated Combination Approach Targeting Better Visual Outcomes Drives Commercial Value First and only therapy to have demonstrated superior visual outcomes over anti-VEGF-A therapy with a novel and highly differentiated MOA Only asset in near or long-term pipeline with potential to disrupt treatment paradigm on basis of efficacy in wet AMD Concentrated prescriptions in U.S. enables potential self-commercialization opportunity with lean and targeted organization 2 3 4 MOA – Mechanism of Action
