Use of Non-GAAP Financial Measures

Sonendo's financial results are prepared in accordance with generally accepted accounting principles in the United States of America ("GAAP"). In this press release, in addition to financial measures reported in accordance with 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, long-lived asset impairment charges and transaction costs, net of payments received, related to the Company's attempted acquisition of Biolase, and financing costs ("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, impairments of long-lived assets and transaction costs, net of payments received, related to the Company's attempted acquisition of Biolase, and financing costs recorded herein. In addition to the explanations provided above, the Company's excludes transaction costs, net of payments received, related to the Company's attempted acquisition of Biolase and financing costs in the calculations of Adjusted EBITDA because such amounts are infrequent and highly volatile in nature as such transactions are not a core component of the Company's strategy nor its recurring operations.

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 (burn) 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 (burn) to measure progress on its capital efficiency and cash flow initiatives.

The following tables present reconciliations of various financial measures calculated in accordance with GAAP to those Non-GAAP measures that exclude (or, in the case of free cash flow burn, include) items specified in the tables. The GAAP measures shown in the tables below represent the most comparable GAAP measure to the applicable non-GAAP measures shown in the table.

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.
