Exhibit 99.1

FORTE BIOSCIENCES, INC. ANNOUNCES FIRST QUARTER 2024 RESULTS AND

PROVIDES BUSINESS UPDATE

DALLAS, TX – MAY 13, 2024 – Forte Biosciences, Inc. (www.fortebiorx.com) (NASDAQ: FBRX), a clinical-stage biopharmaceutical company focused on autoimmune and autoimmune-related diseases, today announced first quarter 2024 results and provided a business update.

First Quarter 2024 Business Highlights

“Forte continues to make excellent progress with FB102. As we indicated last quarter, the single ascending dose (SAD) portion of the FB102 phase 1 trial was successfully completed. We expect the dosing of the multiple ascending dose (MAD) cohorts of the phase 1 trial in the healthy volunteers to complete around mid-year. To date, FB102 has demonstrated a good safety profile, including in the MAD cohorts.” said Paul Wagner, Ph.D., Chairman and Chief Executive Officer of Forte Biosciences. “We look forward to initiating patient-based studies before the end of the year. We believe the data to date supports the significant potential for FB102 across a variety of autoimmune and autoimmune-related diseases with large addressable markets and we look forward to addressing these opportunities as we continue to advance the FB102 program.”

First Quarter 2024 Operating Results

Research and development expenses were $4.4 million for the three months ended March 31, 2024, compared to $4.8 million for the same period in 2023. The decrease was primarily due to a decrease of approximately $2.7 million in manufacturing costs partially offset by an increase of approximately $1.4 million in clinical expenses as we advanced our FB102 program through clinical trials, and a net increase of approximately $0.9 million in payroll and related expenses due to an increase in our average headcount.

General and administrative expenses were $3.5 million for the three months ended March 31, 2024, compared to $2.1 million for the same period in 2023. The increase was primarily due to increases in legal and professional expenses.

Net losses per share were ($0.16) and ($0.32) for the three months ended March 31, 2024 and 2023, respectively.

Forte ended the first quarter 2024 with approximately $30.4 million in cash and cash equivalents. Forte had approximately 36.4 million shares of common stock outstanding as of March 31, 2024.
