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

On September 28, 2023, Sonendo, Inc. (the “Company”) received notice (the “Notice”) from the New York Stock Exchange (the “NYSE”) that the Company was not in compliance with the continued listing standard set forth in Section 802.01C of the NYSE’s Listed Company Manual (“Section 802.01C”) because the average closing price of the Company’s common stock, par value $0.001 per share (the “Common Stock”), was less than $1.00 per share over a consecutive 30 trading-day period (the “minimum share price requirement”). The Notice has no immediate impact on the listing of the Common Stock on the NYSE, subject to the Company’s compliance with the NYSE’s other continued listing requirements.

Pursuant to Section 802.01C, the Company has a period of six months following the receipt of the Notice to regain compliance with the minimum share price requirement. The Company may regain compliance at any time during the six-month cure period if on the last trading day of any calendar month during the six-month cure period the Common Stock has a closing share price of at least $1.00 and an average closing share price of at least $1.00 over the 30 trading-day period ending on the last trading day of that month. If the Company is unable to regain compliance with the minimum share price requirement within the cure period, the NYSE will initiate procedures to suspend and delist the Common Stock. However, if the Company determines that it will cure the minimum share price requirement by taking an action that will require stockholder approval, the Company must so inform the NYSE and must obtain stockholder approval no later than its next annual meeting, and must implement the action promptly thereafter.

Section 802.01C requires the Company to notify the NYSE, within 10 business days of receipt of the Notice, of its intent to cure this deficiency. The Company intends to notify the NYSE of its intent to regain compliance with the requirements of Section 802.01C.

The Notice does not affect the Company’s business operations or its reporting obligations with the Securities and Exchange Commission.

Item 7.01 Regulation FD Disclosure.

On October 2, 2023, the Company issued a press release related to the foregoing. A copy of the press release is attached as Exhibit 99.1 to this Current Report and is incorporated by reference to this Item 7.01.

The information in this Item 7.01, including Exhibit 99.1, is being furnished and shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and is not to be incorporated by reference into any filing by Company under the Securities Act of 1933, as amended, or the Exchange Act, regardless of any general incorporation language contained in such filing, unless otherwise expressly stated in such filing.

Exhibit 99.1

Sonendo, Inc. Announces Receipt of Notice of Non-Compliance with NYSE Trading Share Price Listing Rule

October 2, 2023

LAGUNA HILLS, Calif.--(BUSINESS WIRE)--Sonendo, Inc. (NYSE: SONX) (“Sonendo” or the “Company”), a leading dental technology company and developer of the GentleWave® System, today announced that on September 28, 2023, it received notice (the “Notice”) from the New York Stock Exchange (the “NYSE”) that the Company is not in compliance with applicable price criteria in the NYSE’s continued listing standard set forth in the NYSE Listed Company Manual because the average closing price of the Company’s common stock, par value $0.001 per share (the “Common Stock”), was less than $1.00 per share over a consecutive 30 trading-day period. The Notice does not result in the immediate delisting of the Company’s common stock from the NYSE.

The Company intends to respond to the NYSE within 10 business days of receipt of the Notice of its intent to cure the deficiency. In accordance with NYSE rules, the Company has a period of six months following the receipt of the Notice to regain compliance with the minimum share price requirement. The Company may regain compliance at any time within the six-month cure period if on the last trading day of any calendar month during the cure period the Company has a closing share price of at least $1.00 and an average closing share price of at least $1.00 over the 30 trading-day period ending on the last trading day of that month.

Under the NYSE’s rules, if the Company determines that it will cure the stock price deficiency by taking an action that will require stockholder approval at its next annual meeting of stockholders, the price condition will be deemed cured if the price promptly exceeds $1.00 per share, and the price remains above that level for at least the following 30 trading days.

The Company’s Common Stock will continue to be listed and trade on the NYSE during this period, subject to the Company’s compliance with other NYSE continued listing standards. The receipt of the Notice does not affect the Company’s business, operations or reporting requirements with the Securities and Exchange Commission.
