QSI in focus: Quantum-Si receives Nasdaq minimum bid price notice, faces January 19 compliance deadline

Nasdaq's Listing Qualifications Department delivered a written deficiency notice to Quantum-Si Incorporated on July 23, 2026. The trigger: Class A common stock (QSI) had closed below $1.00 per share for 30 consecutive business days, breaching the minimum bid price requirement under Nasdaq Listing Rule 5450(a)(1). Trading on The Nasdaq Global Market continues uninterrupted, and the notice carries no immediate effect on the listing or the company's SEC reporting obligations.

The 180-day window

Nasdaq has provided Quantum-Si an initial compliance period of 180 calendar days, running through January 19, 2027. The cure threshold is specific: the closing bid price must hold at or above $1.00 for a minimum of 10 consecutive business days. Nasdaq's Listing Qualifications Staff retains discretion to extend that 10-day window under Rule 5810(c)(3)(H), though the 8-K filed by Chief Financial Officer Jeffry Keyes on July 24, 2026 carries no assurance that such discretion will be applied.

The secondary path if the first window closes

Missing the January deadline does not trigger immediate delisting, but the conditions for a second chance are more demanding. Quantum-Si would need to transfer its listing from The Nasdaq Global Market to The Nasdaq Capital Market, satisfy the continued listing standard for market value of publicly held shares, meet all other initial listing requirements except the bid price threshold, pay a Nasdaq application fee, and file written notice committing to cure the deficiency through a reverse stock split if necessary. That second compliance window, also 180 calendar days, is available only if Nasdaq's Staff agrees the company can cure the deficiency.

If Staff concludes otherwise, or if the second period expires without a qualifying run of closes above $1.00, a formal delisting notice follows. Quantum-Si could then appeal to a Nasdaq Hearings Panel. The filing is explicit that no assurance exists that any such appeal would succeed.

What to watch

Quantum-Si, headquartered at 29 Business Park Drive in Branford, Connecticut, said it intends to monitor the closing bid price and will consider all available options. No specific remediation plan was disclosed. The first milestone on the tape is 10 consecutive closes at or above $1.00 before January 19, 2027.
