THIOGENESIS APPOINTS DR. GILAD AHARON TO ITS BOARD OF DIRECTORS

Thiogenesis Therapeutics Corp. has appointed Gilad Aharon, PhD, to its board of directors.

Dr. Aharon is a co-founder and portfolio manager at Rosalind Advisors Inc., a Toronto-based life science institutional investor. The appointment follows Rosalind Advisors' investment in Thiogenesis's recently completed, non-brokered private placement. Dr. Aharon holds a PhD in biophysics and molecular biology from the University of Toronto.

"Gil brings significant experience and depth of insight in the life sciences sector, and we look forward to working together in advancing TTI-0102," said Dr. Patrice Rioux, chief executive officer of Thiogenesis.

Dr. Aharon added: "Thiogenesis has taken a disciplined approach to developing TTI-0102, with a clear focus on its late-stage cystinosis program while continuing development in primary mitochondrial disease, including Leigh syndrome spectrum disorders. By joining the board, Rosalind is committing to support the company's execution on a clear set of near-term clinical and regulatory objectives addressing areas of high unmet medical needs."

The company also wishes to announce that, further to its news release of June 3, 2026, the TSX Venture Exchange has issued its final acceptance for the company's previously announced non-brokered private placement.
