You should read the following discussion and analysis of our financial condition and results of operations together with our unaudited condensed consolidated financial statements and the related notes included elsewhere in this Quarterly Report and with our audited financial statements and related notes thereto and management’s discussion and analysis of financial condition and results of operations for the year ended December 31, 2025, included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission, or the SEC, on March 31, 2026. This discussion and analysis and other parts of this Quarterly Report contain forward-looking statements based upon current beliefs, plans and expectations related to future events and our future financial performance that involve risks, uncertainties and assumptions, such as statements regarding our intentions, plans, objectives, expectations, forecasts and projections. Our actual results and the timing of selected events could differ materially from those anticipated in these forward-looking statements as a result of several factors, including those set forth under the section titled “Part II, Item 1A — Risk Factors” and elsewhere in this Quarterly Report.

Overview

Kodiak Sciences (“we”, the “Company” or “Kodiak”) is a precommercial retina focused biotechnology company committed to researching, developing and commercializing transformative therapeutics. We are focused on bringing new science to the design and manufacture of next generation retinal medicines to prevent and treat the leading causes of blindness globally. Our Antibody Biopolymer Conjugate (ABC) Platform uses molecular engineering to merge the fields of protein-based and chemistry-based therapies and has been at the core of our discovery engine. We are developing a portfolio of three late-stage clinical programs, two of which are derived from our ABC platform and one which is platform-independent.

Our lead investigational medicine, Zenkuda (tarcocimab), is an anti-VEGF antibody biopolymer conjugate under development for the treatment of high prevalence retinal vascular diseases. Zenkuda is being developed as a mainstay intravitreal biologic monotherapy that provides high immediacy, driven by the enhanced formulation, and high durability, driven by the ABC platform and our science of durability, with the ultimate objective of providing, once approved, a flexible 1-month through 6-month label for all patients with retinal vascular disease (treatment-naïve, treatment-experienced, mild patients and severe patients). Zenkuda has completed four successful Phase 3 pivotal studies: the Phase 3 GLOW1 and GLOW2 studies in diabetic retinopathy (DR), the Phase 3 BEACON study in retinal vein occlusion (RVO) and the Phase 3 DAYLIGHT study in wet AMD. Zenkuda is currently being studied in one Phase 3 clinical trial, DAYBREAK in patients with wet AMD. DAYBREAK has completed enrollment and topline data for the one-year primary endpoint are expected in September 2026. We intend to file a Biologics License Application (BLA) in DR, RVO and wet AMD in 2026.

KSI-501, our second investigational medicine, is a first-in-class anti-IL-6, VEGF-trap bispecific therapy built on our ABC platform and is being developed for high prevalence retinal vascular diseases to address the leading unmet needs of extended durability and targeting disease biology beyond VEGF for differentiated efficacy. KSI-501 is designed to provide high immediacy/efficacy and high durability. KSI-501 is currently being studied in the Phase 3 DAYBREAK study in patients with wet AMD. DAYBREAK has completed enrollment and topline data for the one-year primary endpoint are expected in September 2026. In August 2026, we also announced the initiation of the Phase 3 ALTO study of KSI-501 in patients with Diabetic Macular Edema (DME).

KSI-101, our third investigational medicine, is a high strength (100 mg/mL) antibody-based therapy with a bispecific mechanism of action targeting both interleukin-6 (IL-6) and VEGF. We are developing KSI-101 for patients with macular edema (retinal fluid) secondary to inflammation (MESI). Data from our dose-finding Phase 1b APEX study demonstrated robust anatomical and visual responses across MESI patients. More than half of patients achieved ≥15-letter gains in best corrected visual acuity (BCVA), with additional benefit at higher dose levels. Rapid vision improvements and anatomical response was observed with 10-letter gains by Week 4 in top dose groups and OCT central subfield thickness (CST) 325 microns achieved as early as Week 1 in top dose groups. Continued anatomical improvement was observed over time with 90% resolution of intraretinal (IRF) and subretinal fluid (SRF) by Week 8 and 20/25 Snellen visual acuity by Week 20. In top dose groups, ≥90% achieved complete absence of IRF and SRF, indicating retinal dryness and normalization of retinal architecture. KSI-101 also continued to be well tolerated with a favorable safety profile. The top two dose levels in APEX have been advanced into the Phase 3 pivotal studies, PEAK and PINNACLE. Enrollment of the first 300-patient cohort in the PEAK trial supporting Pivotal Analysis 1 has completed and topline results are expected in December 2026. Completion of enrollment in the second pivotal cohort evaluating 600 subjects across the PEAK and PINNACLE studies is expected in 4Q 2026, with topline clinical data release anticipated in 2Q 2027.

With regards to our pipeline programs, dual cytokine-targeting bispecific antibody programs KSI-102 (anti-TNFa/IL-6) and KSI-103 (anti-IL-1/IL-6) continue to progress through pre-IND activities, targeting diseases of ocular inflammation. Retina duet programs in glaucoma and geographic atrophy (GA) built with ABC platform continue to progress.

Our VETi (Visual Engagement Technology and imager) program has achieved significant advancements in hardware, software and algorithms development. VETi is our AI- and machine-learning-enabled wearable headset with applications in retina care alongside broader opportunities in identity security and cognitive sciences.

We have a dedicated commercial-scale drug substance manufacturing facility that was custom-designed and built in collaboration with Lonza. We believe these manufacturing capabilities could position us for potential market share capture if tarcocimab and KSI-501 are approved.

Zenkuda (tarcocimab) Clinical Program Update

Zenkuda is an investigational anti-VEGF therapy built on our proprietary ABC Platform. Zenkuda has a mean ocular half-life in humans of 20 days, approximately three times longer than approved anti-VEGF therapies, and is designed to maintain effective drug levels in ocular tissues for longer. Zenkuda is being developed as a mainstay intravitreal biologic monotherapy that provides high immediacy, driven by the enhanced formulation, and high durability, driven by the ABC platform and our science of durability, with the ultimate objective of providing, once approved, a flexible 1-month through 6-month label for all patients with retinal vascular disease (treatment-naïve, treatment-experienced, mild patients, and severe patients).

Zenkuda has completed four successful Phase 3 pivotal studies: the Phase 3 GLOW1 and GLOW2 studies in diabetic retinopathy (DR), the Phase 3 BEACON study in retinal vein occlusion (RVO), and the Phase 3 DAYLIGHT study in wet AMD. In the GLOW1 and GLOW2 studies, Zenkuda successfully treated DR patients and prevented disease progression with 100% of patients on extended 6-month dosing at Year 1. In the BEACON study, during the first 6 months, Zenkuda-treated patients were dosed at 8-week intervals (as opposed to 4-week intervals for aflibercept). In the second 6 months, identical retreatment criteria were used for the Zenkuda and aflibercept arms, and nearly half of Zenkuda patients did not require any treatment while achieving similar vision and anatomical outcomes as the aflibercept group at one year. In the DAYLIGHT study, Zenkuda demonstrated non-inferior efficacy results and compelling safety and tolerability at a once-monthly dosing interval. Zenkuda is currently being studied in the Phase 3 DAYBREAK study in wet AMD, the final anticipated Phase 3 study in the program. In DAYBREAK, patients are treated on an every 1-month through every 6-month treatment interval, depending on an AI-driven assessment of disease activity. Topline results for the DAYBREAK one-year primary endpoint are expected in September 2026.

About GLOW1 and GLOW2

GLOW1 and GLOW2 were prospective, randomized, double-masked, sham-controlled, multicenter Phase 3 studies evaluating Zenkuda 5mg in participants with diabetic retinopathy. Both studies employed extended-interval dosing regimens with an ultimate treatment interval of every six months. The primary endpoint was the proportion of eyes improving by ≥2 steps on the Diabetic Retinopathy Severity Scale (DRSS) from baseline at Week 48. Additional outcome measures include the proportion of eyes developing a sight-threatening complication of diabetic retinopathy and the proportion of eyes improving ≥3 steps on DRSS from baseline at Week 48.

In the GLOW1 study, patients were randomized 1:1 to receive either sham injections or Zenkuda via intravitreal injection at baseline, Week 8, Week 20 and Week 44, for a planned four injections in year one. The Phase 3 GLOW1 study demonstrated that, with extended 6-month dosing in every patient, Zenkuda can achieve strong efficacy both in treating existing disease (primary endpoint) and preventing vision threatening complications and disease progression (key secondary endpoint). In GLOW1, Zenkuda met its primary endpoint of the proportion of patients with at least a 2-step improvement on the DRSS score with 41.1% of Zenkuda-treated patients demonstrating at least a 2-step improvement versus 1.4% of patients in the sham group, a 29-fold increased response rate ratio (p-value less than 0.0001). Zenkuda also met all key secondary endpoints, including greater reductions in the proportion of patients developing sight-threatening complications (such as diabetic macular edema and proliferative diabetic retinopathy) versus sham, demonstrating an 89% decreased risk (2.3% with Zenkuda versus 21.0% with sham, p-value 0.0001).

The Phase 3 GLOW2 study was designed as a confirmatory study to the Phase 3 GLOW1 study. Patients were randomized 1:1 to receive either sham injections or Zenkuda via intravitreal injection at baseline, Week 4, Week 8, Week 20 and Week 44, for a planned five injections in year one. The Phase 3 GLOW2 study confirmed findings from GLOW1 that, with extended 6-month dosing in all Zenkuda-treated patients, Zenkuda can achieve strong efficacy both in treating existing disease (primary endpoint) and preventing vision threatening complications and disease progression (key secondary endpoint). In GLOW2, Zenkuda met its primary endpoint of the proportion of patients with at least a 2-step improvement on the DRSS, with 62.5% of Zenkuda-treated patients demonstrating at least a 2-step improvement versus 3.3% of patients in the sham group, a 19-fold increased response rate ratio (p-value 0.0001). Zenkuda also met all key secondary endpoints, including greater reductions in the proportion of patients developing sight-threatening complications (such as DME and proliferative DR), versus sham, demonstrating an 85% decreased risk (2.4% with Zenkuda versus 15.8% with sham, p-value ≤ 0.0001).
