EYP-1901 TREAT TO MAINTAIN IN WET AMD 22 | INVESTOR PRESENTATION

DAVIO Clinical Trial Data Supports Advancing EYP-1901 As A Maintenance Treatment For Wet AMD About half of eyes in DAVIO could go up to 6 months on EYP-1901 alone Another ~30% received only a single supplemental anti-VEGF during 6-months About 15 % failed both SoC and EYP-1901 and required multiple supplements TREAT TO MAINTAIN WITH EYP-1901 23 | INVESTOR PRESENTATION

EYP-1901 Is Advancing As A Potential Maintenance Therapy In Wet AMD Treat newly diagnosed patients with anti-VEGF of choice to reach desired “dry” outcome Maintain with EYP-1901on six-month intervals providing new MOA and sustained delivery Supplement with current anti-VEGF biologic, if needed 24 | INVESTOR PRESENTATION Based on DAVIO Phase 1 outcomes, we believe over half of all wet AMD eyes may be maintained visually and anatomically with EYP-1901 alone
