Securities registered pursuant to Section 12(b) of the Act:

Indicate by check mark whether the registrant is an emerging growth company as defined in Rule 405 of the Securities Act of 1933 (§ 230.405 of this chapter) or Rule 12b-2 of the Securities Exchange Act of 1934 (§ 240.12b-2 of this chapter).

On October 11, 2022, Eloxx Pharmaceuticals, Inc. (the “Company”) received a written notification letter (the “Notice”) from the Listing Qualifications Department of The Nasdaq Stock Market (“Nasdaq”) notifying the Company that, for the last 30 consecutive business days, the Company’s Minimum Value of Listed Securities, as defined by Nasdaq (“MVLS”), has been below the minimum $35 million requirement for continued listing on The Nasdaq Capital Market under Nasdaq Listing Rule 5500(b)(2) (the “Minimum Market Value Requirement”).

The Notice has no immediate effect on the listing of the Company’s common stock, and its common stock will continue to trade on The Nasdaq Capital Market under the symbol “ELOX,” subject to the Company’s compliance with the other continued listing requirements of The Nasdaq Capital Market.

In accordance with Nasdaq Listing Rule 5810(c)(3)(C), the Company has 180 calendar days, or until April 10, 2023, to regain compliance with the Minimum Market Value Requirement. The Notice states that, to regain compliance, the Company’s minimum MLVS must close at $35 million or more for a minimum of ten (10) consecutive business days during the compliance period ending April 10, 2023.

If the Company does not regain compliance with the Minimum Market Value Requirement during the compliance period ending April 10, 2023, Nasdaq will provide written notification that the Company’s common stock will be subject to delisting. At that time, the Company may appeal any such delisting determination to a Nasdaq hearings panel.

The Company intends to actively monitor the Company’s MLVS and evaluate available options to regain compliance with the Minimum Market Value Requirement. While the Company is exercising diligent efforts to maintain the listing of its common stock on The Nasdaq Capital Market, there can be no assurance that the Company will be able to regain compliance with the Minimum Market Value Requirement during the 180-day compliance period or maintain compliance with the other listing requirements of The Nasdaq Capital Market.
