Turn Therapeutics to Present at Stifel 2026

Virtual Immunology and Inflammation Forum

Westlake Village, Calif. – September

10, 2026 - Turn Therapeutics Inc. (Nasdaq: TTRX), a clinical-stage biotechnology company developing targeted, localized therapies

for inflammatory skin diseases, today announced that Bradley Burnam, Chief Executive Officer, and Stephen M. Hahn, M.D., Executive Clinical

Date: September 23, 2026

The presentation will provide a detailed look at the Company’s atopic dermatitis clinical program, including its pruritus-focused

stage 2 enrichment strategy and emerging findings across distinct patient populations. These include patients with moderate-severe baseline

(IGA).

A replay of the webcast will be available on the Turn Therapeutics website for approximately six months following the presentation.
