Material Changes vs. Prior Period

• Increased Net Loss: Net loss increased by approximately $1.85 million (22.9%) compared to Q1 2024, driven primarily by higher R&D expenses.
• R&D Expense Growth: R&D expenses rose by $1.24 million (20.1%), attributed to increased external clinical development costs and personnel costs, partially offset by lower preclinical expenditures.
• Decreased Interest Income: Total other income decreased by $0.81 million (62.0%) due to lower investment balances and decreased interest rates on marketable securities.
• Cash Position: Cash and cash equivalents decreased by $4.18 million during the quarter. Total liquid assets (cash + marketable securities) stood at $90.06 million at quarter-end.
• Debt Structure: The Hercules Credit Facility remains outstanding at $15.0 million principal. The maturity date was extended to April 1, 2026, via the Fourth Amendment in September 2024, with an interest rate of the greater of Prime + 3.10% or 11.10%.

Guidance, Outlook, and Risks

• Reproxalap Regulatory Status: On April 3, 2025 (post-period end), the FDA issued a Complete Response Letter (CRL) regarding the resubmitted NDA for reproxalap, stating it failed to demonstrate efficacy and requiring at least one additional adequate and well-controlled study. The company intends to resubmit the NDA mid-year 2025 pending FDA discussions.
• AbbVie Option Agreement: As of May 14, 2025, AbbVie has not exercised its exclusive option to co-develop and commercialize reproxalap. The option period extends until 10 business days following an FDA decision on the NDA. If exercised, Aldeyra could receive a $100 million upfront payment (net of prior fees) and up to $300 million in milestones.
• Liquidity Outlook: Management believes current cash, cash equivalents, and marketable securities are sufficient to fund operations and debt obligations into 2027, excluding potential licensing revenue. However, the company will require additional funding for future development and commercialization.
• Legal Proceedings: A securities class action lawsuit filed in July 2023 was dismissed with prejudice by the court on March 14, 2025.
• Portfolio Updates: The company ceased development of the Helio Product Candidate (ADX-2191 for proliferative vitreoretinopathy) in 2024. Development of ADX-629 for chronic cough and idiopathic nephrotic syndrome was de-prioritized in early 2024.

Investor Verification Checklist

• Reproxalap Path Forward: Verify the specific design and timeline of the "additional adequate and well-controlled study" required by the FDA following the April 2025 CRL.
• AbbVie Option Exercise: Monitor for any announcement regarding AbbVie's decision to exercise the option, which is critical for funding and commercialization strategy.
• Cash Burn Rate: Assess the sustainability of the current cash position ($90.1 million) against the projected costs of the required additional clinical trial and ongoing operations.
• Debt Covenants: Review the Hercules Credit Facility terms to ensure compliance with covenants, particularly given the extended maturity and interest rate structure.
• Stock-Based Compensation: Note the significant non-cash expense ($2.22 million in Q1) and its impact on future cash flow projections.
