As previously disclosed, on December 10, 2021, Frequency Therapeutics, Inc. (the “Company” or “Frequency”) entered into an Equity Distribution Agreement (the “Sales Agreement”) with Oppenheimer & Co. Inc. (“Oppenheimer”) to sell shares of the Company’s common stock, par value $0.001 per share (the “Common Stock”), for aggregate gross sales proceeds of up to $125.0 million, from time to time, through an “at the market” equity offering program, with Oppenheimer acting as sales agent.

On September 26, 2023, the Company delivered written notice to Oppenheimer of termination of the Sales Agreement pursuant to Section 11(b) thereof, effective immediately. The Company is not subject to any termination penalties related to the termination of the Sales Agreement. As of September 26, 2023, the Company had sold 12,767 shares of Common Stock for net proceeds, after deducting sales agent commissions, of approximately $50,000.

A copy of the Sales Agreement was filed as Exhibit 1.1 to the Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission on December 10, 2021 (the “December 2021 8-K”).The description of the Sales Agreement contained in this Current Report on Form 8-K does not purport to be complete and is qualified in its entirety by reference to the copy of the Sales Agreement filed as Exhibit 1.1 to the December 2021 8-K.

As previously reported, the Company received a deficiency letter from the Listing Qualifications Department of the Nasdaq Stock Market LLC (“Nasdaq”) on March 28, 2023 indicating that, based on the closing bid price for the last 30 consecutive business days, the Company was not in compliance with the $1.00 minimum bid price requirement for continued listing on The Nasdaq Global Select Market, as set forth in Nasdaq Listing Rule 5450(a)(1) (the “Bid Price Rule”). In accordance with Nasdaq Listing Rule 5810(c)(3)(A), the Company was provided a period of 180 calendar days, or until September 25, 2023 (the “Initial Compliance Date”), to regain compliance with the Bid Price Rule.

On September 12, 2023, the Company applied to transfer the listing of the Common Stock from the Nasdaq Global Select Market to the Nasdaq Capital Market (the “Transfer”). On September 26, 2023, Nasdaq notified the Company that the Transfer was approved and that, in connection with the Transfer, the Company had an additional 180 calendar day period, or until March 25, 2024 (the “Extended Compliance Date”), to regain compliance with the Bid Price Rule. The Transfer will become effective at the opening of business on September 28, 2023. The Common Stock will continue to trade under the symbol “FREQ.” The Nasdaq Capital Market is a continuous trading market that operates in substantially the same manner as The Nasdaq Global Select Market, and listed companies must meet certain financial requirements and comply with Nasdaq’s corporate governance requirements.

The Company intends to continue to monitor the closing bid price of the Common Stock and plans to effect a reverse stock split to regain compliance with the Bid Price Rule. There can be no assurance that the Company will be able to regain compliance with the Bid Price Rule or will otherwise be in compliance with other Nasdaq listing criteria.
