oPublished results in *Frontiers in Immunology* linking inflammation and oxidative stress to the progression of Parkinson's disease.

------

oPublished results in the Journal *NeuroImmune Pharmacology and Therapeutics* demonstrating COYA 303's synergistic enhancement of regulatory T cell function and protection against Treg apoptosis (cell death).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪Announced the issuance of a U.S. patent relevant to its investigational ready-to-use (RTU) liquid formulation of IL-2. Through an existing agreement, Coya has the exclusive *in vivo* rights to this patent and other related intellectual property spanning multiple indications both as monotherapy and combination therapies.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪2H 2026: Publication of *in vivo* COYA 303 data in inflammatory animal model of peripheral and CNS inflammation.

"2025 was a year of meaningful clinical and scientific progress for Coya," said Dr. Arun Swaminathan, PhD, Chief Executive Officer of Coya Therapeutics. "We advanced COYA 302 across multiple programs and key regulatory milestones, generated encouraging translational data validating our combination-based approach, and strengthened our balance sheet to support execution through our next major clinical milestones. We enter

------

2026 with strong momentum and a clear path forward to advance our COYA 302 program patients with ALS and FTD."

Dr. Fred Grossman, DO, FAPA, President and Chief Medical Officer of Coya Therapeutics added, "We are encouraged by the continued clinical, regulatory, and scientific momentum across our pipeline, which supports our strategy of targeting immune imbalance and neuroinflammation through regulatory T cell enhancement. We are pleased to be actively enrolling the ALSTARS trial across the US and Canada."

**Financial Results**

As of December 31, 2025, Coya had cash and cash equivalents of $46.8 million.

Collaboration revenues were $7.9 million for the year ended December 31, 2025, compared to $3.6 million for the year ended December 31, 2024. The increase was primarily due to a $3.6 million increase in License revenue and a $0.7 million increase in R&D services revenue. License revenue totaled $6.7 million for the year ended December 31, 2025, arising from milestone payments received upon FDA acceptance of our IND for COYA 302 for the treatment of ALS and the dosing of the first patient in our ALSTARS trial.

Research and development (R&D) expenses were $16.7 million for the year ended December 31, 2025, compared to $11.9 million for the year ended December 31, 2024. The change was primarily due to a $4.9 million increase in our clinical expenses due to our clinical advancement of COYA 302 in ALS, a $1.4 million increase in internal research and development expenses, and a $0.4 million increase in sponsored research, partially offset by a $1.8 million decrease in our preclinical expenses.

In-process research and development was $2.3 million for the year ended December 31, 2025, compared to $0 for the year ended December 31, 2024. This increase was a result of milestone payments made pursuant to our license agreements which were due upon FDA acceptance of our IND for COYA 302 for the treatment of ALS and FTD and upon the dosing of the first patient in our ALSTARS trial.

General and administrative expenses were $11.4 million for the year ended December 31, 2025, and $8.9 million for the year ended December 31, 2024, a change of approximately $2.5 million. The increase was primarily due to a $1.6 million increase in payroll and employee related benefits, a $0.6 million increase in professional service fees and a $0.3 million increase in our investor and public relations costs.

Net loss was $21.2 million for the year ended December 31, 2025, compared to net loss of $14.9 million for the year ended December 31, 2024.

Dysfunctional Tregs underlie numerous conditions, including neurodegenerative, metabolic, and autoimmune diseases. This cellular dysfunction may lead to sustained inflammation and oxidative stress resulting in lack of homeostasis of the immune system.

Coya's investigational product candidate pipeline leverages multiple therapeutic modalities aimed at restoring the anti-inflammatory and immunomodulatory functions of Tregs. Coya's therapeutic platforms include Treg-enhancing biologics, Treg-derived exosomes, and autologous Treg cell therapy.
