[8-K] Nautilus Biotechnology, Inc. Reports Material Event

Rhea-AI Filing Summary

Insights

Listing & Exchanges Analyst

Compliance restored; continued Nasdaq listing preserved.

Nautilus Biotechnology confirmed compliance with Nasdaq’s minimum bid-price rule after maintaining closes at or above $1.00 for at least ten consecutive business days. Nasdaq indicated the compliance matter is closed, which supports ongoing trading on The Nasdaq Capital Market.

This follows a prior deficiency notice tied to sub-$1.00 bids and a market transfer on October 29, 2025. While operational performance isn’t addressed here, maintaining listing status avoids the administrative and liquidity challenges associated with potential delisting.

Item 8.01. Other Events

On November 3, 2025, Nautilus Biotechnology, Inc. (the “Company”) received a written notice from the Listing Qualifications staff (the “Staff”) of The Nasdaq Stock Market LLC (“Nasdaq”) informing the Company that it has regained compliance with Nasdaq’s Listing Rule 5550(a)(2) for continued listing on The Nasdaq Capital Market, as the closing bid price of the Company’s common stock had met or exceeded $1.00 per share for a minimum of ten consecutive business days and that the matter is now closed.

As previously disclosed in a current report on Form 8-K filed with the Securities and Exchange Commission on May 2, 2025, the Company received a letter from the Staff indicating that, based upon the closing bid price of shares of the Company’s common stock for the 30 consecutive business day period between March 19, 2025, through April 30, 2025, the Company did not meet the minimum bid price of $1.00 per share required for continued listing on the Nasdaq Global Select Market pursuant to Nasdaq Listing Rule 5450(a)(1) (the “Minimum Bid Price Requirement”). Pursuant to Listing Rule 5810(c)(3)(A), the Company was granted 180 calendar days, or until October 28, 2025, to regain compliance with the Minimum Bid Price Requirement. Subsequently, on October 29, 2025, the Company transferred to The Nasdaq Capital Market and was afforded the remainder of The Nasdaq Capital Market’s second 180 calendar day compliance period, or until April 27, 2026, to regain compliance with the Minimum Bid Price Requirement.
