Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On June 18, 2025, Unity Biotechnology, Inc. (the “Company”) received a notification from The Nasdaq Stock Market (“Nasdaq”) that for the last 30 consecutive business days, the closing bid price of the Company’s common stock was below $1.00 per share, which is the minimum required closing bid price for continued listing on the Nasdaq Global Select Market pursuant to Listing Rule 5450(a)(1).

This notice has no immediate effect on the Company’s Nasdaq listing or trading of its common stock. In accordance with Nasdaq Listing Rule 5810(c)(3)(A), the Company has 180 calendar days, or until December 15, 2025, to regain compliance. To regain compliance, the closing bid price of the Company’s common stock must be at least $1.00 per share for a minimum of ten consecutive business days. If the Company does not regain compliance by December 15, 2025, the Company may be eligible for a second 180-calendar-day period, provided that the Company meets the continued listing requirement for market value of publicly held shares and all other initial listing requirements for Nasdaq, other than the minimum bid price requirement, and the Company provides written notice to Nasdaq of its intention to cure the deficiency during the second compliance period. Qualification for a second compliance period also requires that the Company has submitted, no later than December 15, 2025, an application to transfer to the Nasdaq Capital Market, which the Company had submitted on June 9, 2025, as discussed below. If the Company is not eligible for the second compliance period or Nasdaq staff concludes that the Company will not be able to cure the deficiency during the second compliance period, Nasdaq will provide written notice to the Company that the Company’s common stock will be subject to delisting. In the event of such notification, the Company may appeal Nasdaq’s determination to delist its securities, but there can be no assurance that Nasdaq would grant the Company’s request for continued listing.

In addition, and as previously disclosed on March 17, 2025, on March 14, 2025, the Company received a separate letter from Nasdaq notifying the Company that its stockholders’ equity as reported in its Annual Report on Form 10-K had fallen below the minimum stockholders’ equity requirement of at least $10,000,000 for continued listing on The Nasdaq Global Select Market set forth in Nasdaq Listing Rule 5450(b)(1)(A). The letter further indicated that, as of the date of the letter, the Company did not comply with certain requirements under the alternative standards set forth in Nasdaq Listing Rules 5450(b)(2) and 5450(b)(3) for continued listing on the Nasdaq Global Select Market. On April 28, 2025, the Company timely submitted a plan of compliance to Nasdaq requesting until August 15, 2025 to regain compliance with the stockholders’ equity requirement. As part of its efforts to regain compliance, on June 9, 2025, the Company also submitted an application to transfer to The Nasdaq Capital Market.

The Company intends to evaluate measures available to regain compliance under the Nasdaq Listing Rules and remain listed on Nasdaq. There can be no assurance that the Company will be able to regain compliance with the minimum bid price or stockholders’ equity requirements, or will otherwise remain in compliance with other Nasdaq Listing Rules or that the Company’s common stock will not be delisted from Nasdaq.
