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.

Use of Non-GAAP Financial Measures

Sonendo' financial results are prepared in accordance with generally accepted accounting principles in the United States of America ("GAAP"). This press release and the reconciliation tables included in the financial schedules below include non-GAAP gross profit, non-GAAP gross margin and non-GAAP loss from operations (collectively, the "Non-GAAP measures"). Non-GAAP gross profit and non-GAAP gross margin exclude impairment of long-lived assets. Non-GAAP loss from operations exclude, as applicable, stock-based compensation expense, depreciation and amortization and impairment of long-lived assets. Management believes that Non-GAAP measures are 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 measures, 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 for each of the Non-GAAP measures 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 measures presented herein to GAAP measures, the most directly comparable GAAP financial measure, please see "Reconciliation of GAAP to Non-GAAP Gross Profit and Gross Margin" and "Reconciliation of GAAP to Non-GAAP Loss from Operations" in the financial schedules below.
