Item 2.02 Results of Operations and Financial Condition.
On August 7, 2024, Sonendo, Inc. (the “Company”) issued a press release announcing its financial results for the quarter ended June 30, 2024 and updating its revenue guidance for 2024 (the “Press Release”). A copy of the Press Release is being furnished as Exhibit 99.1 to this Current Report on Form 8-K.
As provided in General Instruction B.2 of Form 8-K, the information in this Item 2.02 of this Current Report on Form 8-K (including Exhibits 99.1 and 99.2) shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be incorporated by reference into any registration statement or other document filed under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such filing.
Discussion of Non-GAAP Financial Measure
In the Press Release, in addition to financial measures reported in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”), the Company provides various non-GAAP financial measures, including (1) gross profit and gross margin excluding certain excess and obsolete inventory charges, long-lived asset impairment charges, and stock-based compensation expense (“Adjusted Gross Profit” and “Adjusted Gross Margin”), (2) earnings (loss) before income tax expense, interest and financing costs, net, depreciation and amortization, excluding certain excess and obsolete inventory charges, stock-based compensation expense, and long-lived asset impairment charges (“Adjusted EBITDA Loss”), and (3) the sum of net cash used in operating activities and purchases of property and equipment (“Free Cash Flow (Burn)”).
Management believes that the presentation of Adjusted Gross Profit, Adjusted Gross Margin, Adjusted EBITDA Loss and Free Cash Flow (Burn) (collectively, the “Non-GAAP Measures”) 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 the 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 (or, in the case of Free Cash Flow (Burn), included in) 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. These 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.
Adjusted Gross Profit and Adjusted Gross Margin
Adjusted Gross Profit and Adjusted Gross Margin represent GAAP Gross Profit and GAAP Gross Margin, respectively, excluding the impact of the following items recorded in cost of sales:
- Excess and obsolete inventory charges related to recently discontinued products. Management excludes this item when evaluating the Company’s operating performance because of its unusually occurring nature and the significant volatility of these charges, which are related to infrequent discrete decisions to phase out or discontinue specific products.
- Impairments of long-lived assets. Management excludes this item when evaluating the Company’s operating performance because these amounts represent costs that are capitalizable as purchases of long-lived assets, but for GAAP purposes are then immediately impaired under ASC 360. Such immediate impairments are not indicative of the Company’s ongoing operational performance.
- Stock-based compensation. Management excludes this item when evaluating the Company’s operating performance because it is a non-cash expense.
Adjusted EBITDA Loss
Adjusted EBITDA Loss consists of GAAP earnings (loss) before income tax expense, interest and financing costs, net, depreciation and amortization (“EBITDA”), excluding the impact of stock-based compensation, excess and obsolete inventory charges related to recently discontinued products, and impairments of long-lived assets, recorded herein. See explanation above for the rationale of exclusion of these items from the EBITDA.
Free Cash Flow (Burn)
Free Cash Flow (Burn) is calculated by subtracting (adding) cash used to purchase property and equipment expenditures from (to) net cash flows provided by (used in) operating activities. Free cash flow is an important indicator of how much cash is generated or used by the Company’s business operations, including capital expenditures. Management uses free cash flow to measure progress on its capital efficiency and cash flow initiatives.
For a reconciliation of the Non-GAAP Measures presented herein to the most directly comparable GAAP financial measure, please see the “Reconciliation of GAAP to Non-GAAP Measures” section in the Press Release.
The Company may, in the future, incur expenses of a nature similar to many of the non-GAAP adjustments described above, and exclusion (or inclusion) of these items from (in) its Non-GAAP Measures should not be construed as an inference that all of these costs are unusual, infrequent or non-recurring.
The Company recently revised its methodology for calculating the Non-GAAP Measures. The revised calculations for each of the quarterly periods from January 1, 2023 through June 30, 2024 are being furnished as Exhibit 99.2 to this Current Report on Form 8-K.

Sonendo, Inc. Reports Second Quarter 2024 Financial Results and Raises Full Year Revenue Guidance
LAGUNA HILLS, CA – August 7, 2024 – Sonendo, Inc. (“Sonendo” or the “Company”) (OTCQX: SONX), a leading dental technology company and developer of the GentleWave® System, today reported financial results for the second quarter ended June 30, 2024.
Recent Highlights
- Generated $8.3 million total revenue for second quarter of 2024 and carried over a healthy console backlog for the second straight quarter;
- Drove substantial increases in GAAP gross margin and adjusted gross margins (non-GAAP) to 37.5% and 40.7%, respectively, based primarily on lower manufacturing and console warranty costs;
- Significantly reduced GAAP operating loss to $6.7 million and adjusted EBITDA (non-GAAP) loss to $5.7 million, a 61% and 55% improvement, respectively, compared to the second quarter of 2023; and
- Raised 2024 full year revenue guidance range to $31 to $32 million, from prior guidance of $29 to $31 million
“We are very encouraged by the early results of the strategic reset we embarked earlier this year,” said Bjarne Bergheim, President and Chief Executive Officer of Sonendo. “We are driving commercial discipline through a refined go-to-market strategy and we are exceeding our own timelines for delivering on gross margin expansion, all while dramatically reducing operating expenses and free cash flow burn through a leaner, more efficient organizational structure. Additionally, the increased reliability of the GentleWave® G4 System has improved the customer experience and enabled us to successfully re-engage our legacy customer base through upgrade programs while simultaneously expanding our new-customer base, both of which we expect to drive higher procedure instrument utilization and revenue in the long-term.”
Second Quarter 2024 Financial Results
Except as otherwise indicated, the GAAP and non-GAAP financial measures presented in this press release exclude discontinued operations associated with the Company’s divestiture of its TDO practice management software segment in March 2024.
Total revenue was $8.3 million for the second quarter of 2024, a 5% decrease compared to second quarter of 2023. GentleWave console revenue totaled $2.4 million, a 9% increase compared to the second quarter of 2023, which was comprised of 35 upgrades and a 13 unit increase to the installed base. The Company’s installed base totaled 1,155 as of June 30, 2024. Procedure instrument revenue totaled $4.7 million, a decrease compared to $5.6 million for the prior year quarter. Other product revenue totaled $1.2 million for the second quarter of 2024, a $0.2 million year-over-year increase.
GAAP gross margin for the second quarter of 2024 increased to 37.5%, compared to a negative gross margin of 5.5% for the second quarter of 2023. During the second quarter of 2024 and 2023, respectively, the Company recorded in cost of sales $0.2 million and $2.9 million in excess and obsolete inventory charges related to recently discontinued products. Adjusted gross margin (non-GAAP) for the second quarter of 2024 was 40.7% compared to 28.7% for the prior year quarter.
Total operating expenses for the second quarter of 2024 totaled $9.8 million, a $7.1 million reduction compared to the prior year period.
Operating loss totaled $6.7 million for the second quarter of 2024, a $10.7 million reduction compared to the prior year quarter. Adjusted EBITDA (non-GAAP) loss totaled $5.7 million, a $6.9 million reduction compared to the prior year period.
Net loss from continuing operations totaled $7.4 million for the second quarter of 2024, a $10.7 million reduction compared to the prior year quarter.
Ex. 99.1
Free cash flow burn (non-GAAP), which the Company defines as the sum of net cash used in operating activities and purchases of property and equipment, totaled $(6.7) million for the second quarter of 2024, a $3.0 million improvement compared to the prior year quarter.
As of June 30, 2024, the Company’s cash and cash equivalents and short-term investments totaled $24.2 million, and there were $20.5 million of principal payments outstanding under its term loan facility.
2024 Financial Guidance
For the full year 2024, the Company is increasing its expectations for total revenue from continuing operations to be in the range of $31 to $32 million, compared to previous guidance of $29 to $31 million.

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.
