Kiora Pharmaceuticals Reports Third Quarter 2025 Results; Company Advances Pipeline with Two Actively Enrolling Phase 2 Clinical Trials for Retinal Diseases

Encinitas, California – November 7, 2025 - Kiora Pharmaceuticals, Inc. (NASDAQ: KPRX) ("Kiora" or the "Company") today announced third quarter 2025 financial results and provided an update on its pipeline of small molecules for the treatment of retinal diseases.

Key third quarter and 2025 year-to-date corporate highlights include:

•Continued recruitment and patient dosing in KLARITY, an open-label Phase 2 clinical trial evaluating KIO-104 for the treatment of patients with retinal inflammation.

•Continued recruitment and patient dosing in the ABACUS-2 trial, a Phase 2, randomized, controlled clinical trial of KIO-301 for vision restoration in patients with retinitis pigmentosa.

•In the third quarter of 2025, Kiora received $1.2 million in reimbursed R&D expenses from Théa Open Innovation (“Théa”) for activities related to KIO-301 performed in the second quarter of 2025. The Company billed $1.5 million in the third quarter of 2025 for reimbursable R&D expenses, of which $0.3 million was received within the quarter.

•Ended the quarter with $19.4 million in cash, cash equivalents and short-term investments, along with $1.2 million in collaboration receivables and $1.5 million in tax and research credit receivables.

•Maintained projected cash runway into late 2027, a timeframe beyond anticipated data readouts for both KLARITY and ABACUS-2, with potential for further extension through achievement of partnership milestones.

"Both of our Phase 2 clinical trials continue to recruit, screen, and dose participants. Further, we continue to explore adding more trial centers to expand the geographic footprint and accelerate enrollment in both trials,” said Brian M. Strem, Ph.D., President & Chief Executive Officer of Kiora. "For ABACUS-2, screening and enrollment has been expanded by patients who participated in Kiora’s functional endpoint validation study. This endpoint validation study remains open for patients with less severe vision loss, representing an additional population of individuals potentially helped by KIO-301. We are also maintaining close collaboration with our partners, Théa and Senju, who will be instrumental in potential registration studies and global commercialization.

“KLARITY enrollment is targeting patients with one of several inflammatory retinal diseases that cause macular edema in this two-stage, multi-dose study. As part of the design, we have a pre-defined sentinel assessment of safety and tolerability.

“Collectively, the progress across both studies represents the execution of our strategy to advance a diversified pipeline targeting rare and common retinal diseases, with each asset having potential to address several indications.”

Third Quarter Financial Highlights

“Our cash position continues to support an anticipated runway into late 2027, well beyond the anticipated clinical readouts for both ABACUS-2 and KLARITY,” said Melissa Tosca, Chief

Financial Officer. “This outlook is further supported by an approximate $1.0 million income tax receivable, resulting from changes under the OBBBA enacted in July 2025 that modified the treatment of capitalized R&D. These revisions provide greater flexibility in applying prior R&D expenses against net income. We continue to manage our capital efficiently, maintaining a stable G&A spend while increasing R&D investment that is partially offset by reimbursement from our strategic partner.”

Kiora ended the third quarter of 2025 with $19.4 million in cash, cash equivalents, and short-term investments. The Company also recorded $1.2 million in collaboration receivables from Théa for reimbursable R&D expenses and $1.5 million in tax and other receivables, of which 1.0 million is from income tax receivables and $0.5 million is related to research tax credits.

R&D expenses for the third quarter of 2025 were $2.7 million, before recognizing $1.7 million in reimbursable expenses from Théa. In comparison, R&D expenses for the third quarter of 2024 were $2.1 million, with $0.9 million in offsetting reimbursable expenses from Théa. The increase in R&D for the third quarter of 2025 was mainly attributed to clinical trial activities. G&A expenses were $1.4 million for the third quarter of 2025, consistent with $1.4 million in the third quarter of 2024.

The Company reported net income of $27 thousand for the third quarter of 2025, compared to a net loss of $3.4 million in the third quarter of 2024. The improvement was driven by favorable tax impacts, noncash gains from the remeasurement of existing contingent consideration liabilities, and continued control of operating costs.
