Other Events.
As previously reported, on September 13, 2023, Rapid Micro Biosystems, Inc. (the “Company”) received a notification letter from the Nasdaq Listing Qualifications Staff (the “Staff”) of The Nasdaq Stock Market LLC notifying the Company that the bid price for the Company’s Class A common stock, par value $0.01 (the “common stock”) had closed below $1.00 per share for thirty (30) consecutive business days (July 31, 2023 through September 11, 2023) and that, as a result, the Company was not in compliance with the minimum bid price requirement for continued inclusion on the Nasdaq Global Select Market under Nasdaq Listing Rule 5550(a)(2) (the “Bid Price Requirement”). The Company was provided a period of 180 calendar days, until March 11, 2024, to regain compliance with the Bid Price Requirement.

On September 26, 2023, the Company was informed by the Staff that it had regained compliance with the Bid Price Requirement following ten (10) consecutive business days (September 12, 2023 through September 25, 2023) during which the closing bid price of Company’s common stock was equal to or greater than $1.00 per share, and that this matter was closed.
