## Exhibit 99.1

**Exhibit 99.1**![LOGO](g77724g1114045905211.jpg)

**FORTE BIOSCIENCES, INC. ANNOUNCES THIRD QUARTER 2025 RESULTS AND PROVIDES UPDATE** 

*Three clinical trial readouts for FB102 expected in 2026, including phase 2 in celiac disease and phase 1b in both vitiligo and alopecia areata* 

**DALLAS, TX – NOVEMBER 14, 2025** – Forte Biosciences, Inc. (<u>www.fortebiorx.com</u>) (NASDAQ: FBRX), a clinical-stage biopharmaceutical company focused on autoimmune and autoimmune-related diseases, today announced its third quarter 2025 financial results and provided a business update.

"We continue to make excellent progress with FB102." said Forte Biosciences CEO Paul Wagner, PhD. "The US IND is now open and enrolment in the FB102 phase 2 celiac disease (CeD) clinical trial has expanded to US sites with topline results expected in 2026. Based on the strength of the positive results from the FB102 phase 1b CeD trial, which we reported in June, we look forward to the phase 2 data further validating FB102 for the treatment of celiac disease. The FB102 phase 1b vitiligo clinical study is ongoing and we continue to expect topline data in 1H26. We have also begun enrolling patients in the phase 1b trial in alopecia areata and expect data from that study in 2026. With 3 key clinical trial readouts for FB102, 2026 will be a very eventful year and further highlight FB102's potential to address the significant unmet medical needs across multiple indications including celiac disease, vitiligo and alopecia areata, which represent multi-billion dollar potential market opportunities."

<u>Q3 2025 Operating Results</u> 

Research and development expenses were $15.2 million for the three months ended September 30, 2025, compared to $5.9 million for the same period in 2024. The increase was primarily due to increases of $9.7 million in clinical and manufacturing expenses related to our Phase 2 clinical trial for celiac disease and Phase 1b clinical trials for vitiligo and alopecia areata, and $0.8 million in personnel-related expenses due to an increase in headcount, partially offset by a decrease of $1.2 million in preclinical expenses as a result of toxicology work performed in 2024.

Research and development expenses were $36.5 million for the nine months ended September 30, 2025, compared to $16.0 million for the same period in 2024. The increase was primarily due to an increase of $21.6 million in manufacturing and clinical expenses of our Phase 2 clinical trial for celiac disease and Phase 1b clinical trials for vitiligo and alopecia areata, an increase of $0.9 million in discovery work, and an increase of $0.9 million in personnel-related expenses due to an increase in headcount, partially offset by a decrease of $2.8 million in preclinical expenses as a result of toxicology work performed in 2024.

Our research and development expenses may increase as we continue to advance FB102 through a celiac Phase 2 trial including a US arm as a result of the FDA approving our IND, multiple Phase 1b clinical trials and as we pursue additional autoimmune indications.

------

General and administrative expenses were $3.2 million for the three months ended September 30, 2025 compared to $2.8 million for the same period in 2024. The increase was primarily due to $0.6 million in personnel-related expenses including $0.5 million in non-cash stock-based compensation partially offset by decreases in professional expenses and legal expenses, including litigation and settlement expenses of $0.3 million.

General and administrative expenses were $9.6 million for the nine months ended September 30, 2025 compared to $13.3 million for the same period in 2024. The decrease was primarily due to decreases in professional expenses and legal expenses, including litigation and settlement expenses, of $6.0 million, partially offset by an increase of $2.1 million in personnel-related expenses including additional non-cash stock-based compensation of $1.9 million.

Our general and administrative expenses may fluctuate in the future due to fluctuations in professional and advisory fees as we build out our infrastructure to advance FB102 through a Phase 2 and multiple Phase 1b clinical trials and pursue additional autoimmune indications.

Net losses per share were $(0.99) and $(4.54) for the three months ended September 30, 2025 and 2024, and $(3.26) and $(15.35) for the nine months ended September 30, 2025 and 2024, respectively.

Forte ended the third quarter of 2025 with $93.4 million in cash and cash equivalents. There are approximately 12.5 million shares of common stock and 5.3 million prefunded warrants outstanding as of September 30, 2025.
