Equillium removes Nasdaq delisting risk by restoring bid price compliance.

Equillium received confirmation from Nasdaq on August 29, 2025 that it complies again with the minimum bid price rule. This follows earlier notices in December 2024 and June 2025 that its common stock had traded below the $1.00 per share threshold required for The Nasdaq Capital Market.

The company achieved compliance by maintaining a closing bid price of at least $1.00 per share for 10 consecutive business days, with this condition met on August 28, 2025. This outcome means the stock remains listed on The Nasdaq Capital Market under the existing Bid Price Rule.

Maintaining listing status can be important for trading liquidity and access to capital, and this notice indicates that, as of late August 2025, the specific bid price deficiency has been cured under Nasdaq’s rules.
