Quantum-Si Inc. Receives Nasdaq Notice Over Sub-$1 Stock Price

What Happened

• Quantum-Si Inc. (QSI) announced it received a written notice from Nasdaq on July 23, 2026 stating the company no longer meets Nasdaq Global Market's minimum bid price requirement because the closing bid for its Class A common stock has been below $1.00 per share for 30 consecutive business days. The notice does not immediately affect the listing or trading of QSI, which continues to trade under the symbol "QSI."

Key Details

• Nasdaq rule cited: Listing Rule 5450(a)(1) (minimum $1.00 bid price).
• Compliance period: Initial 180-calendar-day cure period under Nasdaq Listing Rule 5810(c)(3)(A) ends January 19, 2027.
• Cure requirement: Closing bid must be at least $1.00 per share for a minimum of 10 consecutive business days (unless Nasdaq grants discretion to alter this period).
• If not cured by January 19, 2027, QSI may be eligible for an additional 180-day period if it transfers to the Nasdaq Capital Market and meets other initial listing standards (except the bid price); the company may need to effect a reverse stock split and pay a Nasdaq application fee.
• If Nasdaq determines the deficiency cannot be cured, the Staff may begin delisting proceedings; the company may appeal to a Nasdaq Hearings Panel, but there is no assurance an appeal will succeed.
• Filing signed by Jeffry Keyes, Chief Financial Officer, dated July 24, 2026.

Why It Matters

• For investors: the notice signals that QSI currently fails a Nasdaq listing requirement and must regain a $1.00 closing bid for the specified time to avoid further compliance steps. Trading and SEC reporting remain unchanged for now, but failure to regain compliance could lead to delisting proceedings and related administrative actions described above. The company said it will monitor its stock price and consider options to regain compliance.
