About Sonendo

Sonendo is a commercial-stage medical technology company focused on saving teeth from tooth decay, the most prevalent chronic disease globally. Sonendo develops and manufactures the GentleWave® System, an innovative technology platform designed to treat tooth decay by cleaning and disinfecting the microscopic spaces within teeth without the need to remove tooth structure. The system utilizes a proprietary mechanism of action, which combines procedure fluid optimization, broad-spectrum acoustic energy and advanced fluid dynamics, to debride and disinfect deep regions of the complex root canal system in a less invasive procedure that preserves tooth structure. The clinical benefits of the GentleWave System when compared to conventional methods of root canal therapy include improved clinical outcomes, such as superior cleaning that is independent of root canal complexity and tooth anatomy, high and rapid rates of healing and minimal to no post-operative pain. In addition, the GentleWave System can improve the workflow and economics of dental practices. Sonendo is also the parent company of TDO® Software, the developer of widely used endodontic practice management software solutions, designed to simplify practice workflow. TDO Software integrates practice management, imaging, referral reporting and CBCT imaging, and offers built-in communication with the GentleWave System.

Forward Looking Statements

In addition to background and historical information, this press release contains "forward-looking statements" based on Sonendo's current expectations, forecasts and beliefs including statements related to Sonendo's 2023 financial guidance. These forward-looking statements are subject to inherent uncertainties, risks, and assumptions that are difficult to predict. Actual outcomes and results could differ materially due to a number of factors, including the degree of market acceptance of our products by dental practitioners and our ability to maintain strong working relationships with our customers, risks associated with manufacturing our products in large-scale commercial quantities, our dependence on third party suppliers, our ability to raise capital when needed, and our ability to comply with extensive government regulation and oversight. These and other risks and uncertainties include those described more fully in the company's Annual Report on Form 10-K for the year ended December 31, 2022 filed with the U.S. Securities and Exchange Commission (SEC) on March 8, 2023 under the sections titled "Risk Factors" and "Management's Discussion and Analysis of Financial Condition and Results of Operation", as well as any reports that we may file with the SEC in the future. Forward-looking statements contained in this announcement are based on information available to Sonendo as of the date hereof.

Use of Non-GAAP Financial Measures

Sonendo's financial results are prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP"). This press release and the reconciliation tables included in the financial schedules below include non-GAAP loss from operations. Non-GAAP loss from operations exclude, as applicable, stock-based compensation expense and depreciation and amortization. Management believes that non-GAAP loss from operations is useful in helping identify the company's core operating performance and enables management to consistently analyze the period-to-period financial performance of the core business operations. Management also believes that non-GAAP loss from operations, will enable investors to assess the company in the same way that management has historically assessed the company's operating results against comparable companies with conventional accounting methodologies. The company's definition of non-GAAP loss from operations has limitations as an analytical tool and may differ from other companies reporting similarly named measures. Non-GAAP measures should not be considered measures of financial performance under GAAP, and the items excluded from such non-GAAP measures should not be considered in isolation or as alternatives to financial statement data presented in the financial statements as an indicator of financial performance or liquidity. Non-GAAP measures should be considered in addition to results prepared in accordance with GAAP but should not be considered a substitute for or superior to GAAP results.

For a reconciliation of our non-GAAP loss from operations presented herein to GAAP loss from operations, the most directly comparable GAAP financial measure, please see "Reconciliation of GAAP to Non-GAAP Loss from Operations" in the financial schedules below.
