Quantum BioPharma is trading 5.25% up at $3.10, with no reliable source attributing the advance to a new announcement or confirmed catalyst.
- The move follows a volatile session after plans to voluntarily delist Class B shares from the Canadian Securities Exchange; September 4, 2026 is expected to be the final CSE trading day.
- Nasdaq, Frankfurt, and Upstream listings remain active.
- Broader markets are modestly lower, so sentiment does not clearly explain the advance.
