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

On August 9, 2019, Sienna Biopharmaceuticals, 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 February 5, 2020, 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 February 5, 2020, 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. 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.

The Company intends to take all reasonable 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 market value requirements, or will otherwise be in compliance with other Nasdaq Listing Rules.
