Fourth Quarter 2021 Financial Results

Total revenue was $9.9 million in the fourth quarter 2021, an increase from $8.7 million in the fourth quarter 2020. Growth in the quarter was driven primarily by increased utilization among our current install base and increased GentleWave console sales. GentleWave console revenue was $3.1 million in the fourth quarter 2021, an increase from $2.8 million in the fourth quarter 2020. Procedure instrument revenue was $3.8 million, an increase from $3.3 million in the fourth quarter 2020. Software revenue was $2.2 million, an increase from $2.0 million in the fourth quarter 2020. As of December 31, 2021, GentleWave ending install base was approximately 820 units.

Gross margin for fourth quarter 2021 was 25%, compared to 20% in the fourth quarter 2020. The increase in gross margin was driven primarily by a reduction in charges relating to excess inventory and improved overhead absorption.

Total operating expenses in the fourth quarter 2021 were $16.0 million, compared to $13.2 million in the fourth quarter 2020. The increase was primarily driven by sales team hiring and higher general and administrative costs, primarily legal and accounting. This was partially offset by lower research and development expenses.

Loss from operations was $13.6 million in the fourth quarter 2021, compared to $11.4 million in the fourth quarter 2020. Non-GAAP loss from operations was $11.9 million in the fourth quarter 2021 compared to $10.3 million in the fourth quarter 2020.

Gross margin for 2021 was 25% compared to 17% for 2020. The increase in gross margin was driven primarily by a reduction in charges relating to excess inventory and improved overhead absorption.

Total operating expenses for 2021 were $52.7 million, compared to $46.7 million for 2020. The increase was primarily driven by sales team hiring and higher general and administrative costs, primarily legal and accounting.

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.
