1. Organization and Basis of Presentation

Description of Business

Sonendo, Inc. (“Sonendo” or the “Company”) was incorporated in June 2006 pursuant to the laws of the State of Delaware under the name Dentatek Corporation. In March 2011, the Company changed its name to Sonendo, Inc. The Company is a medical technology company that has developed and is commercializing the GentleWave System to treat tooth decay. The Company’s principal market is the United States. The Company’s products include the GentleWave System, which is cleared by the United States (“U.S.”) Food and Drug Administration (“FDA”) for sale in the U.S. and approved by Health Canada in Canada, along with the system’s sterilized, single-use procedure instruments ("PIs"). In addition, the Company offers practice management software to enable an integrated digital office for dental practitioners.

Basis of Presentation

The Company’s financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission (“SEC”) on a consistent basis with the Company’s annual financial statements and in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, considered necessary for a fair statement of the Company’s financial information. Accordingly, the accompanying unaudited condensed consolidated financial statements do not include all of the information and notes required by GAAP for complete financial statements. The condensed consolidated balance sheet as of December 31, 2022 included herein was derived from the audited financial statements as of that date. The results of operations included in these condensed consolidated financial statements are not necessarily indicative of the results of operations to be expected for the year, any other interim period, or for any other future annual or interim period. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. GAAP have been condensed, consolidated, or omitted. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022 filed with the SEC on March 8, 2023.

Liquidity

On September 27, 2022, the Company completed a private placement (the "Private Placement"), issuing an aggregate of approximately 23.0 million shares of its common stock at a purchase price of $0.95 per share and pre-funded warrants to purchase an aggregate of 43.3 million shares of common stock at a purchase price of $0.949 per pre-funded warrant. The pre-funded warrants have an exercise price of $0.001 per share of common stock, are immediately exercisable and will remain exercisable until exercised in full. The aggregate net proceeds from the Private Placement, after deducting placement agent fees and other offering expenses, were $59.0 million. See Note 5, Stockholders' Equity, for additional information.

As of ~~March 31,~~June 30, 2023, the Company had cash and cash equivalents and short-term investments of $~~74.9~~65.9 million.

The Company has a limited operating history, and the revenue and income potential of the Company’s business and market are unproven. The Company has experienced net losses and negative cash flows from operations since its inception and as of ~~March 31,~~June 30, 2023 had an accumulated deficit of $~~384.5~~402.2 million. During the ~~three~~six months ended ~~March 31,~~June 30, 2023, the Company incurred net losses of $~~15.4~~33.1 million and used $~~17.0~~26.3 million of cash and cash equivalents in operations. In ~~April~~the three months ended June 30, 2023, ~~the Company has~~we received ~~approximately $3.2~~ ~~million payment~~all of the ~~total~~ $4.4 million ~~related to~~payment of Employee Retention Credit ("ERC") recognized in other income in 2022. The Company will continue to incur significant costs and expenses related to its ongoing operations until it gains market acceptance of its products and achieves a level of revenues adequate to support its operations.

The accompanying unaudited condensed consolidated financial statements have been prepared assuming the Company will continue as a going concern, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The unaudited condensed consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of this uncertainty. Based on its current operating plan, the Company expects that its existing cash and cash equivalents and short-term investments will be sufficient to fund its operating expenses and capital expenditure requirements for at least 12 months from the date of issuance of the accompanying unaudited condensed consolidated financial statements.

The Company plans to fund its operations, capital funding and other liquidity needs, using existing cash, cash equivalents and short-term investments and, to the extent available, cash generated from commercial operations. If the Company's actual operating expenses significantly exceed its operating plan or its debt financing arrangements become unavailable because certain borrowing requirements are not met (see Note 9), the Company may have to significantly delay or scale back its operations to reduce working capital requirements. In addition, the Company would prioritize necessary and appropriate steps to enable the continued operations of the business and preservation of the value of its assets beyond the next 12 months, including but not limited to, actions such as reducing personnel-related costs and delaying or curtailing the Company’s commercial efforts, development activities and other discretionary expenditures that are within the Company’s control. These reductions in expenditures, if required, may have an adverse impact on the Company’s ability to achieve certain of its planned objectives.

On March 10, 2023, the California Department of Financial Protection and Innovation shut down Silicon Valley Bank (SVB) due to liquidity concerns and appointed the Federal Deposit Insurance Corporation (FDIC) as receiver. On ~~Sunday, March 12, 2023, the U.S. Treasury Department, Federal Reserve and FDIC announced that all bank depositors would have access to their money starting Monday, March 13, 2023. On~~ March, 27, 2023, SVB began operating as a division of First Citizens Bank. As of ~~March 31,~~June 30, 2023, the Company held approximately $~~0.6~~0.9 million in operating accounts at SVB. The Company’s remaining cash and cash equivalents and short-term investments, consisting of money market funds, high-grade corporate securities, and U.S. government backed securities, reside in custodial accounts held by U.S. Bank. There has been no disruption to the Company's operations.

Effects of the Macroeconomic Environment ~~and COVID-19~~

The Company’s unaudited condensed consolidated financial statements as of and for the ~~three~~six months ended ~~March 31,~~June 30, 2023 reflect the Company’s estimates of the impact of the macroeconomic environment, including the impact of inflation and higher interest ~~rates, and the COVID-19 pandemic.~~rates. The duration and the scope of these conditions cannot be predicted; therefore, the extent to which these conditions will directly or indirectly impact the Company’s business, results of operations and financial condition, is uncertain. The Company is not aware of any specific event or circumstance that would require an update to its estimates, judgments and assumptions or a revision of the carrying value of the Company’s assets or liabilities as of the date of this filing.

The COVID-19 pandemic negatively impacted the Company's operations, revenue and overall financial condition, and may negatively impact its operations, revenue, and overall financial condition in the future if new and more transmissible vaccine-resistant variants emerge. The Company's customers, including endodontists, have experienced significant financial hardship and some of them may never fully recover. The Company has also experienced disruptions, and may experience future disruptions, including: delays in capital and clinical sales representatives becoming fully trained and productive; difficulties and delays in dental practitioner outreach and training dental practitioners to use its GentleWave System; travel restrictions; delays in initiation, enrollment and follow-ups of its clinical studies; challenges with maintaining adequate supply from third-party manufacturers of components and finished goods and distribution providers; and access to dental practitioners for training and case support.

The Company expects that any future restrictions on dental procedures, as a result of COVID-19 or the emergence of any vaccine resistant variant or other pandemic, epidemic or infectious disease outbreak, and other related issues including supply chain disruptions, would have a negative impact on its ~~operations, revenue and overall financial condition.~~

Operating Segments

The Company has business activity and operates two operating and reportable segments: Product and Software. Operating segments are defined as components of an enterprise for which discrete financial information is available and evaluated regularly by the chief operating decision maker, who is the Company’s chief executive officer (“CEO”), for the purpose of allocating resources and evaluating performance.

Emerging Growth Company Status

The Company is an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012 (the "JOBS Act"). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has elected to avail itself of this exemption and, therefore, for new or revised accounting standards applicable to public companies, the Company will be subject to an extended transition period until those standards would otherwise apply to private companies.

2. Summary Accounting Policies and Recent Accounting Pronouncements

The accounting policies followed by the Company are set forth in Part II, Item 8, Note 2, Summary of Accounting Policies, of the Notes to Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2022.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make informed estimates, judgements and assumptions that affect the reported amounts in the unaudited condensed consolidated financial statements and disclosures in the accompanying notes, including estimates of probable losses and expenses, as of the date of the accompanying unaudited condensed consolidated financial statements. Management considers many factors in selecting appropriate financial accounting policies and in developing the estimates and assumptions that are used in the preparation of these unaudited condensed consolidated financial statements. Management must apply significant judgment in this process. In addition, other factors may affect estimates, including the expected business and operational changes, the sensitivity and volatility associated with the assumptions used in developing estimates, and whether historical trends are expected to be representative of future trends. The estimation process often may yield a range of potentially reasonable estimates of the ultimate future outcomes, and management must select an amount that falls within that range of reasonable estimates. Actual results could differ materially from the estimates and assumptions used in the preparation of the accompanying unaudited condensed consolidated financial statements under different assumptions or conditions.

Inventory

Inventory consists of finished products, work-in-process and raw materials and is valued at the lower of cost or net realizable value. Cost may include materials, labor and manufacturing overhead. Cost is determined by the first in first out inventory method. The carrying value of inventory is reviewed for potential impairment whenever indicators suggest that the cost of inventory exceeds the carrying value and management adjusts the inventory to its net realizable value. The Company also periodically evaluates inventory for estimated losses from excess quantities and obsolescence and writes down the cost of inventory to net realizable value at the time such determinations are made. Net realizable value is determined using the estimated selling price, in the ordinary course of business, less estimated costs to complete and dispose.

Revenue Recognition

Contracts with Customers

The Company recognizes revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods and services. Specifically, the Company applies the following five core principles to recognize revenue: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when, or as, the Company satisfies a performance obligation.

Product revenue is generated from sales of the GentleWave Console and related PIs and accessories. Software revenue is generated from sales of TDO's endodontist practice management software licenses. The Company’s products are sold primarily in the United States and Canada directly to customers through its field sales force.

Performance Obligations

The Company’s performance obligations primarily arise from the manufacture and delivery of the GentleWave System, related PIs and accessories, and the delivery or license of TDO software and related ancillary services. Payment terms are typically on open credit terms consistent with industry practice and do not have significant financing components. Consideration may be variable based on volume.

The Company considers the individual deliverables in its product offering as separate performance obligations and assesses whether each promised good or service is distinct. The total contract transaction price is determined based on the consideration expected to be received, based on the stated value in contractual arrangements or the estimated cash to be collected in no-contracted arrangements, and is allocated to the identified performance obligations based upon the relative standalone selling prices of the performance obligations. The stand-alone selling price is based on an observable price offered to other comparable customers. The Company estimates the standalone selling price using the market assessment approach considering market conditions and entity-specific factors including, but not limited to, features and functionality of the products and services, geographies, type of customer and market conditions. The Company regularly reviews and updates standalone selling prices as necessary. The consideration the Company receives in exchange for its goods or services is only recognized when it is probable that a significant reversal will not occur. The consideration to which the Company expects to be entitled includes a stated list price, less various forms of variable consideration. The Company estimates related variable consideration at the point of sale, including discounts, product returns, refunds, and other similar obligations.

Revenue is recognized over time when the customer simultaneously receives and consumes the benefits provided by the Company’s performance. Revenue is recognized at a point in time if the criteria for recognizing revenue over time are not met, and the Company has transferred control of the goods to the customer. Product revenue is recognized at a point in time when the Company has transferred control to the customer, which is generally when title of the goods transfers to the customer. Software is licensed via delivery to the customer or via a service arrangement under which cloud-based access is provided on a subscription basis (software-as-a-service). When a fixed up-front license fee is received in exchange for the delivery of software, revenue is recognized at the point in time when the delivery of the software has occurred. When software is licensed on a subscription basis, revenue is recognized over the respective license period.

The Company also sells extended service contracts on its GentleWave Systems. Sales of extended service contracts are recorded as deferred revenue until such time as the standard warranty expires, which is generally up to two years from the date of sale. Service contract revenue is recognized on a straight-line basis over time consistent with the life of the related service contract in proportion to the costs incurred in fulfilling performance obligations under the service contract.

Revenue for technical support and other services is recognized ratably over the performance obligation period.

The Company generally does not experience returns. If necessary, a provision is recorded for estimated sales returns and allowances and is deducted from gross product revenue to arrive at net product revenue in the period the related revenue is recorded. These estimates are based on historical sales returns and allowances and other known factors. Actual returns and claims in any future period are inherently uncertain and thus may differ from these estimates. If actual or expected future returns and claims are significantly

greater or lower than the reserves established, a reduction or increase to revenue will be recorded in the period in which such a determination is made.

All non-income government-assessed taxes (sales and use taxes) collected from the Company’s customers and remitted to governmental agencies are recorded in accrued expenses until they are remitted to the government agency.

The Company has adopted the practical expedient permitting the direct expensing of costs incurred to obtain contracts where the amortization of such costs would occur over one year or less, and it applied to substantially all the Company’s contracts.

Contract liabilities

The Company recognizes a contract liability when a customer pays for goods or services for which the Company has not yet transferred control. The balances of the Company’s contract liabilities are as follows:

Revenue recognized during the ~~three~~six months ended ~~March 31,~~June 30, 2023 and 2022 that was included in the contract liability balance as of December 31, 2022 and 2021 was $~~0.4~~0.8 million ~~in each year.~~and $0.6 million, respectively .

Disaggregation of revenue

The Company disaggregates revenue from contracts with customers by segment and by the timing of when goods and services are transferred, which depicts how the nature, amount, timing and uncertainty of revenue and cash flows are affected.

The following table provides information regarding revenues disaggregated by segment and the timing of when goods and services are transferred:

No individual customer accounted for more than 10% of sales for the ~~three~~six months ended ~~March 31,~~June 30, 2023 and 2022.

Warranty Reserve

The Company provides a standard warranty on its GentleWave Systems for a specified period of time. For the ~~three~~six months ended ~~March 31,~~June 30, 2023 and 2022, GentleWave Systems sold were covered by the warranty for a period of up to two years from the date of sale. Estimated warranty costs are recorded as a liability at the time of delivery with a corresponding provision to cost of sales. Warranty accruals are estimated based on the current product costs, the Company’s historical experience, management’s expectations of future conditions and standard maintenance schedules. The Company evaluates this reserve on a regular basis and makes adjustments as necessary.

The following table provides a reconciliation of the change in estimated warranty liabilities for the three and six months ended ~~March 31,~~June 30, 2023 and 2022:

Recent Accounting Pronouncements

Changes to GAAP are established by the Financial Accounting Standards Board (“FASB”) in the form of accounting standards updates (“ASU”). ASUs not listed below were assessed and determined not to be applicable or are expected to have minimal impact on the Company’s unaudited condensed consolidated financial statements.

Accounting Pronouncement Recently Adopted

In October 2021, the FASB, issued Accounting Standards Update No. 2021-08, Business Combinations (Topic 805), Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires an entity (acquirer) to recognize and measure contract assets and liabilities acquired in a business combination in accordance with Topic 606, Revenue from Contracts with Customers. This update is effective for fiscal years beginning after December 15, 2022, and interim periods within those fiscal years, with early adoption permitted. The amendments should be applied prospectively to business combinations occurring on or after the effective date of the amendments. The Company early adopted the ASU on January 1, 2023. The adoption did not have an impact on the Company's unaudited condensed consolidated financial statements. The Company will evaluate the impact for each business combination transaction completed hereafter.

4. Fair Value of Financial Instruments

The Company applies fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The Company’s financial instruments consist principally of cash, cash equivalents, short-term investments, accounts receivable, accounts payable, operating lease liabilities, warrant liabilities and a term loan. Fair value is measured as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market. Valuation techniques that are consistent with the market, income or cost approach are used to measure fair value.

The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three levels:

Level 1 – Observable inputs such as unadjusted quoted prices in active markets that are accessible at the measurement date for identical unrestricted assets or liabilities the Company has the ability to access.

Level 2 – Inputs (other than quoted prices included within Level 1) that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active.

Level 3 – Unobservable inputs that are significant to the fair value measurement and reflect the reporting entity’s use of significant management judgment and assumptions when there is little or no market data. Level 3 assets and liabilities include

those whose fair value measurements are determined using pricing models, discounted cash flow methodologies or similar valuation techniques and significant management judgment or estimation. These include the Black-Scholes option-pricing model which uses inputs such as expected volatility, risk-free interest rate and expected term to determine fair market valuation.

Assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurements. The Company reviews the fair value hierarchy classification at each reporting date. Changes in the ability to observe valuation inputs may result in a reclassification of levels for certain assets or liabilities within the fair value hierarchy. The Company did not have any transfers of assets and liabilities between the levels of the fair value measurement hierarchy during the periods presented.

The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable, and certain accrued expenses approximate fair value due to the short-term nature of these items. Accordingly, the Company estimates that the recorded amounts approximate fair market value.

The following table provides the assets and liabilities measured at fair value on a recurring basis and indicate the fair value hierarchy of the valuation techniques utilized by the Company to determine such value at ~~March 31,~~June 30, 2023 and December 31, 2022:

Money market funds and U.S. Treasury securities are highly liquid investments and are actively traded. The pricing information on these investment instruments is readily available and can be independently validated as of the measurement date. This approach results in the classification of these securities as Level 1 of the fair value hierarchy.

Commercial paper, U.S. government agency bonds and corporate bonds are measured at fair value using Level 2 inputs. The Company reviews trading activity and pricing for these investments as of each measurement date. When sufficient quoted pricing for identical securities is not available, the Company uses market pricing and other observable market inputs for similar securities obtained from third party data providers. These inputs represent quoted prices for similar assets in active markets or these inputs have been derived from observable market data. This approach results in the classification of these securities as Level 2 of the fair value hierarchy.

5. Stockholders’ Equity

Warrants

In April 2022, the Company amended its term loan and the warrants previously issued to Perceptive Credit Holdings III, LP (“Perceptive”) and certain of its affiliates to purchase an aggregate of 304,105 shares of its common stock. Such warrants were amended solely to reduce the exercise price of the warrants to $12.00 per share.

Warrants issued and outstanding at ~~March 31,~~June 30, 2023 and December 31, 2022 included 27,397 warrants with an exercise price of $10.95 per share and 304,106 warrants with an exercise price of $12.00 per share in each period. These warrants expire between December 2023 and August 2031.

On September 27, 2022, the Company completed the Private Placement, issuing an aggregate of approximately 23.0 million shares of its common stock at a purchase price of $0.95 per share and pre-funded warrants to purchase an aggregate of 43.3 million shares of common stock at a purchase price of $0.949 per pre-funded warrant to certain institutional investors and accredited investors (the "Purchasers"). The pre-funded warrants have an exercise price of $0.001 per share of common stock, are immediately exercisable and will remain exercisable until exercised in full. The aggregate net proceeds from the Private Placement, after deducting placement agent fees and other offering expenses, were $59.0 million.

The pre-funded warrants include a provision whereby the exercisability of the warrants may be limited if, upon exercise, the warrant holder or any of its affiliates would beneficially own more than 9.99% of the Company's common stock. The threshold is subject to the Purchaser's rights under the pre-funded warrant to increase or decrease such percentage to any other percentage not in excess of 19.99% upon at least 61 days' prior notice from the Purchaser to the Company. As of ~~March 31,~~June 30, 2023, approximately ~~1.1~~1.8 million shares have been issued pursuant to the exercise of pre-funded warrants and ~~42.2~~41.5 million shares underlying the pre-funded warrants remain outstanding.

The pre-funded warrants are classified as equity and are accounted for as a component of additional paid-in capital at the time of issuance. The pre-funded warrants are included in the calculation of basic and diluted loss per share. Pursuant to the terms and conditions of the purchase agreements entered into by the Purchasers, the Company was obligated to file a registration statement with the SEC registering the resale by the Purchasers of the shares of common stock issued to them in the Private Placement and the shares of common stock to be issued to them upon exercise of the pre-funded warrants issued to them in the Private Placement within 45 days of the closing of the Private Placement. On November 4, 2022, the Company filed a registration statement on Form S-3 (File No. 333-268174), as required under the purchase agreements, and the registration statement was declared effective by the SEC on November 16, 2022.

~~There were~~ no ~~options granted during the three months ended March 31, 2023.~~ The weighted-average grant-date fair value of options granted during the ~~three~~six months ended ~~March 31,~~June 30, 2023 and 2022 was $~~5.72~~0.83 and $1.16 per ~~share.~~share, respectively.

The total fair value of shares vested during the ~~three~~six months ended ~~March 31,~~June 30, 2023 and 2022 was $$$~~0.7~~1.6 million and $1.8 million, respectively, in each period.

Certain stock option grants under the 2017 Stock Incentive Plan (the “2017 Plan”) allow the recipient to exercise the options prior to the options becoming fully vested. Under the 2017 Plan, the Company retains the right to repurchase shares of its common shares that have been issued upon early exercise of options at the original issue price. During the three and six months ended ~~March 31,~~June 30, 2023, the

Company did not repurchase any shares. There was no material number of shares of common stock subject to repurchase as of ~~March 31,~~June 30, 2023. Cash received for the early exercise of unvested stock options is initially recorded as a liability and released to equity over the vesting period. There were no early exercised stock options during the three and six months ended ~~March,~~June 30, 2023. During the three and six months ended ~~March 31,~~June 30, 2022, early exercised stock options vested were immaterial.

7. Leases

The Company leases office space under operating leases with expirations ranging from March 2025 to December 2026, some of which include rent escalations or an option to extend the lease for up to three years per renewal. The exercise of lease renewal options is at the sole discretion of the Company.

As of ~~March 31,~~June 30, 2023, the Company has not entered into any leases that have not yet commenced that would entitle the Company to significant rights or create additional obligations.

The Company determines whether a contract is or contains a lease at the inception of the contract. A contract will be deemed to be or contain a lease if the contract conveys the right to control and direct the use of identified property, plant, or equipment for a period of time in exchange for consideration. The Company generally must also have the right to obtain substantially all of the economic benefits from the use of the property, plant, and equipment.

The Company has elected the practical expedient to not separate its lease component from non-lease component for its real estate leases. The Company has elected the practical expedient not to apply the lease recognition requirements to short-term leases with an initial term of 12 months or less.

The Company uses either its incremental borrowing rate or the implicit rate in the lease agreement as the basis to calculate the present value of future lease payments at lease commencement. The incremental borrowing rate represents the rate the Company would have to pay to borrow funds on a collateralized basis over a similar term and in a similar economic environment.

Future minimum lease payments under these leases are as follows:


	Lease Amounts			Lease Amounts
	(in thousands)			(in thousands)
2023 (remaining nine months)	$	999
2023 (remaining six months)				$	628

Weighted average remaining lease term in years		2.99			2.77
Weighted average discount rate		8.79	%		8.80	%

Variable operating lease expenses consist primarily of real estate taxes and insurance. The components of lease expense and related cash flows were as follows:

8. Commitments and Contingencies

Contingencies

The Company is subject to claims and assessments from time to time in the ordinary course of business, including without limitation, actions with respect to intellectual property, employment, regulatory, product liability and contractual matters. In connection with these proceedings or matters, the Company regularly assesses the probability and amount (or range) of possible issues based on the developments in these proceedings or matters. A liability is recorded in the accompanying unaudited condensed consolidated financial statements if it is determined that it is probable that a loss has been incurred, and that the amount (or range) of the loss can be reasonably estimated. The Company’s management does not believe that any such matters, individually or in the aggregate, will have a material adverse effect on the Company’s business, financial condition, results of operations or cash flows.

9. Term Loan

Perceptive loan

On April 6, 2022, the Company entered into Amendment No. 1 (the “First Amendment”) to the Amended and Restated Credit Agreement and Guaranty with Perceptive (the “Perceptive Loan Agreement”). The First Amendment extended the borrowing deadline for the first tranche of $10.0 million of delayed-draw term loans from December 31, 2021 to September 30, 2022~~, subject to the Company having generated at least $36.0~~ ~~million in revenue for the 12 consecutive month period most recently ended prior to the borrowing date. The First Amendment also extended~~ and the borrowing deadline for the second tranche of $10.0 million delayed-draw term loans from March 31, 2022 to June 30, 2023~~, subject to (i) the Company having generated at least $46.0~~ ~~million in revenue for the 12 consecutive month period most recently ended prior to the borrowing date; and (ii) the closing market capitalization of the Company being at least $100.0~~ ~~million on each trading day of the period of~~ 15 ~~consecutive trading days ending on the business day the borrowing notice for the tranche is delivered to Perceptive.~~. The Company borrowed the extended first tranche of $10.0 million onin July ~~29,~~ 2022, ~~and received~~receiving net proceeds of $9.9 ~~million.~~million, and forfeited the extended second tranche on June 30, 2023.

As a condition to entering into the First Amendment, on April 6, 2022, the Company also amended the warrants previously issued to Perceptive and certain of its affiliates to purchase an aggregate of 304,105 shares of its common stock. Such warrants were amended solely to reduce the exercise price of the warrants to $12.00 per share. In August 2022, a portion of these warrants representing 153,421 shares were transferred to a third party and its affiliates.

For the ~~three~~six months ended June 30, 2023~~March 31, 2023~~ and 2022, the interest rate for amounts borrowed under the Perceptive Loan Agreement, as amended, was the greater of the one-month LIBOR and 2.00% plus the applicable margin of 9.25%. On January 13, 2023, the Company entered into Amendment No. 2 (the "Second Amendment") to the Perceptive Loan Agreement to replace the existing benchmark rate from the one-month LIBOR with a one-month Secured Overnight Financing Rate ("SOFR"). All other terms remain unchanged on the original agreement.

For the ~~three~~six months ended June 30, 2023~~March 31, 2023~~ and 2022, the effective interest rate of the Perceptive loan was ~~16.71~~17.23% and ~~14.59~~14.70%, respectively. As of ~~March 31,~~June 30, 2023 and 2022, the fair value of the Perceptive loan approximates its carrying amount.

Future principal repayments on the Perceptive loan as of ~~March 31,~~June 30, 2023, are as follows:


	Principal
	(in thousands)
2026	$	40,000
Total	$	40,000

The Perceptive Loan Agreement, as amended, includes financial covenants that require the Company to (i) maintain, at all times, a minimum aggregate balance of $3.0 million in cash in one or more controlled accounts, and (ii) satisfy certain minimum revenue thresholds, measured for the 12 consecutive ~~month period~~12-month periods ending on each calendar quarter-end until June 30, 2026. These thresholds progressively increase over time, ~~and range~~ranging from $26.4 million for the ~~twelve-month period ended~~consecutive 12-month periods ending September 30, 2021 to $95.3 million for the ~~twelve month period ended~~consecutive 12-month periods ending June 30, 2026. Specifically, the minimum revenue thresholds for the consecutive 12-months period ending on June 30, 2024 and September 30, 2024, are $47.2 million and $52.0 million, respectively. Failure to satisfy these financial covenants would constitute an event of default under the agreement. For the ~~three~~six months ended ~~March 31,~~June 30, 2023,, the Company was in compliance with all financial covenants and conditions required by the outstanding Perceptive Loan Agreement, as amended.

10. Income Taxes

The Company maintains a full valuation allowance against its net deferred tax assets as of ~~March 31,~~June 30, 2023 based on the current assessment that it is not more likely than not these future benefits will be realized before expiration. No material income tax expense or benefit has been recorded given the valuation allowance position and projected taxable losses in the jurisdictions where the Company files income tax returns. The Company has not experienced any significant increases or decreases to its unrecognized tax benefits since December 31, 2022 and does not expect any within the next 12 months.

The Company monitors changes to the tax laws in the states it conducts business and files corporate income tax returns.

Utilization of the net operating loss carryforwards may be subject to substantial annual limitation due to ownership change limitations that may have occurred or that could occur in the future, as required by Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”), as well as similar state provisions. These ownership changes may limit the amount of net operating loss carryforwards that can be utilized annually to offset future taxable income and tax, respectively. In general, an “ownership change,” as defined by Section 382 of the Code, results from a transaction or series of transactions over a three-year period resulting in an ownership change of more than 50 percentage points of the outstanding stock of a company by certain stockholders or public groups. The Company has not completed an analysis regarding the limitation of net operating loss and R&D credit carryforwards as of ~~March 31,~~June 30, 2023.

The Company is subject to U.S. federal and various states income taxes. The federal returns for tax years 2020 through 2022 remain open to examination and the state returns remain subject to examination for tax years 2019 through 2022. Carryforward attributes that were generated in years where the statute of limitations is closed may still be adjusted upon examination by the Internal Revenue Service or other respective tax authorities. All other state jurisdictions remain open to examination.

11. Segment Information

The Company operates and reports its results in two business segments, Product and Software. The Company reports segment information based on the management approach. The management approach designates the internal reporting used by the Company's chief operating decision maker ("CODM") for decision making and performance assessment as the basis for determining the Company’s reportable segments. The performance measures of the Company’s reportable segments are primarily income (loss) from operations. Income (loss) from operations for each segment includes all revenues, related cost of net revenues, gross margin and operating expenses directly attributable to the segment.

The Company’s Product segment includes sales of the Company's GentleWave System console and related accessories and instruments.

The Company’s Software segment includes sales of the Company's traditional software licenses for practice management software to enable an integrated digital office for endodontists.

The following tables present the Company’s segment information for the three and six months ended ~~March 31~~June 30, 2023 and 2022. Cost of sales in the Product segment included a $:1.7 million charge due to reduced sales volumes of the Company's legacy Gen3 console and

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our unaudited condensed consolidated financial statements and the related notes to those statements included elsewhere in this Quarterly Report on Form 10-Q and the audited consolidated financial statements and notes thereto included in Part II, Item 8 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2022. In addition to historical financial information, the following discussion and analysis contains forward-looking statements that involve risks, uncertainties and assumptions. Our actual results and timing of selected events may differ materially from those anticipated in these forward-looking statements as a result of many factors, including those discussed in Item 1A. Risk Factors in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022 and in the filings we make with the Securities and Exchange Commission (the “SEC”) from time to time. See “Cautionary Note Regarding Forward-Looking Statements.”

We are a commercial-stage medical technology company focused on saving teeth from tooth decay, the most prevalent chronic disease globally. We have developed and manufacture 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 GentleWave System employs a sterilized, single-use procedure instrument ("PI"), to transform root canal therapy ("RCT"), by addressing the limitations of conventional methods.

The clinical benefits of our GentleWave System when compared to conventional methods of RCT 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 to the clinical benefits, the GentleWave System can improve the workflow and economics of dental practices. We began scaling commercialization of our current technology in 2017 and are focused on establishing the GentleWave Procedure as the standard of care for RCT.

Our GentleWave System represents an innovative technology platform and approach to RCT. The GentleWave System is a Class II device and has received 510(k) clearance from the FDA for preparing, cleaning, and irrigating teeth indicated for RCT. The key components of our GentleWave System are a sophisticated and mobile console and a pre-packaged, sterilized, single-use PI. The GentleWave System utilizes a proprietary mechanism of action that is designed to combine procedure fluid optimization, broad-spectrum acoustic energy and advanced fluid dynamics to efficiently and effectively reach microscopic spaces within teeth and dissolve and remove tissue and bacteria with minimal or no removal of tooth structure. We have invested significant resources in establishing a broad intellectual property portfolio that protects the GentleWave Procedure and its unique mechanism of action, as well as future capabilities under development. In 2022, we launched the GentleWave G4 System bringing expanded capabilities and capacity to our technology. We believe our GentleWave System transforms the patient and dental practitioner experience and addresses many of the limitations of conventional RCT.

In the United States and Canada, our direct sales force markets and sells the GentleWave System to dental practitioners performing a high volume of root canals as part of their practice. Our commercial strategy and sales model involves a focus on driving adoption of our GentleWave System by increasing our installed base of consoles and maximizing recurring PI revenue through increased utilization. We have been and will continue to expand the size of our sales and clinician support teams to support our efforts of driving adoption and utilization of the GentleWave System. We plan to pursue marketing authorizations and similar certifications to enable marketing and engage in other market access initiatives over time in attractive international regions in which we see significant potential opportunity.

As of ~~March 31,~~June 30, 2023, we had an installed base of approximately ~~1,005~~1,040 GentleWave Systems. We generated revenue of ~~$10.7~~$21.8 million and incurred a net loss of ~~$15.3~~$33.1 million for the ~~three~~six months ended ~~March 31,~~June 30, 2023, compared to revenue of ~~$9.0~~$19.6 million and a net loss of ~~$15.5~~$30.7 million for the ~~three~~six months ended ~~March 31,~~June 30, 2022. As of ~~March 31,~~June 30, 2023, we had cash and cash equivalents and short-term investments of ~~$74.9~~$65.9 million, an accumulated deficit of ~~$384.5~~$402.2 million, and $40.0 million in principal outstanding under our term loan facility. In ~~April~~the three months ended June 30, 2023, we received all of the ~~Company has received approximately $3.2~~$4.4 million payment of ~~the total $4.4 million related to~~ Employee Retention Credit ("ERC") recognized in other income in 2022.

We expect to continue to incur net losses for the next several years. We expect to continue to make significant investments in our sales and marketing organization by increasing the number of U.S. and Canadian sales representatives, expanding our international marketing programs and expanding direct to clinician digital marketing efforts to help facilitate further adoption among existing accounts and to broaden awareness and adoption of our products to new clinicians. We also expect to continue to make investments in research and development, regulatory affairs and clinical studies to develop future generations of our GentleWave products, support regulatory submissions and demonstrate the clinical efficacy of our new products. Moreover, we incur additional expenses as a result of operating as a public company, including legal, accounting, insurance, exchange listing and SEC compliance, investor relations, and other administrative and professional services expenses. As a result of these expenses, we may require additional financing to fund our operations and planned growth.

We believe that our cash and cash equivalents and short-term investments will be sufficient to meet our capital requirements and fund our operations through at least the next 12 months from the date of this Quarterly Report on Form 10-Q. We may also seek additional financing opportunistically. We may seek to raise any additional capital by entering into partnerships or through public or private equity offerings or debt financings, credit or loan facilities or a combination of one or more of these funding sources. The sale of equity or convertible debt securities may result in dilution to our stockholders and, in the case of preferred equity securities or convertible debt, those securities could provide for rights, preferences or privileges senior to those of our common stock. Debt financing, if available, may involve covenants restricting our operations or our ability to incur additional debt. Any debt financing or additional equity that we raise may contain terms that are not favorable to us or our stockholders. If we raise additional capital through collaboration agreements, licensing or divestiture arrangements, or marketing and distribution arrangements, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product or grant licenses that may not be favorable to us. Additional financing may not be available at all, or in amounts or on terms unacceptable to us.

We believe there are several important factors that impact our operating performance and results of operations. We also regularly review several operating and financial metrics to evaluate our business, measure our performance, identify trends affecting our business, formulate our business plan and make strategic decisions. We believe the following factors and key business metrics are important indicators of our performance:

Our unaudited condensed consolidated financial statements as of and for the ~~three~~six months ended ~~March 31,~~June 30, 2023 reflect our estimate of the impact of the macroeconomic environment, including the impact of inflation and higher interest ~~rates and the COVID-19 pandemic.~~rates. The duration and scope of these conditions cannot be predicted; therefore, the extent to which these conditions will directly or indirectly impact our business, results of operations and financial condition, is uncertain. We are not aware of any specific event or circumstance that would require an update to our estimates, judgments and assumptions or a revision of the carrying value of our assets or liabilities as of the date of this filing.

The COVID-19 pandemic negatively impacted our operations, revenue and overall financial condition, and may negatively impact our operations, revenue, and overall financial condition in the future if new and more transmissible vaccine-resistant variants emerge. Our

customers, including endodontists, have experienced significant financial hardship as a result of the COVID-19 pandemic and some of them may never fully recover. We also experienced disruptions, and may experience future disruptions, including: delays in capital and clinical sales representatives becoming fully trained and productive; difficulties and delays in dental practitioner outreach and training dental practitioners to use our GentleWave System; travel restrictions; delays in initiation, enrollment and follow-ups of our clinical studies; challenges with maintaining adequate supply from third-party manufacturers of components and finished goods and distribution providers; and access to dental practitioners for training and case support. The COVID-19 pandemic resulted in, and may in the future result in, significant disruption to the global financial markets, reducing our ability to access capital when needed, which could negatively affect our liquidity.

We have mitigated the disruptions to our supply of certain materials used in the final assembly and packaging of our PIs encountered in early 2022 as a result of the COVID-19 pandemic. We regularly explore different opportunities to implement alternative secondary source suppliers and packaging methods in order to ensure cost effectiveness and that we are able to source sufficient components and materials to manufacture our products. In the event that we are unable to implement new packaging methods or source sufficient components and materials from our current or future suppliers to manufacture enough of our products to satisfy demand, we may need to cease or slow down production and our business operations and financial condition may be materially harmed. Additionally, the costs of certain materials and services have increased in recent years due to the increased demand and supply shortages caused, in large part, by the pandemic. If such inflationary pressures in costs persist, we may not be able to quickly or easily adjust pricing, reduce costs, or implement countermeasures, all of which would adversely impact our business, financial condition, results of operations, or cash flows.

We expect that any future restrictions on dental procedures, as a result of COVID-19 or the emergence of any vaccine resistant variant, and other related issues including supply chain disruptions, would have a negative impact on our ~~operations, revenue and overall financial condition.~~

Our revenue consists primarily of product revenue and software revenue. We generate product revenue on the capital sale of our GentleWave Console and recurring sales of our single-use PIs and accessories. To a lesser extent, we also derive product revenue from service and repair and extended warranty contracts with our existing customers. Software revenue relates to fees we receive for licensing our TDO practice management tool to dental practitioners. We expect our product revenue to increase in absolute dollars as we increase adoption and utilization of our GentleWave System, though revenues may fluctuate from quarter to quarter.

Cost of sales consists primarily of manufacturing overhead costs, material costs, and direct labor to produce our products, warranty, provisions for slow-moving and obsolete inventory, and other direct costs such as shipping and software support. A significant portion of our cost of sales currently consists of manufacturing overhead costs. These overhead costs include personnel compensation, including stock-based compensation expenses, facilities, the cost of production equipment and operations supervision, quality control, material procurement and intangible assets amortization. We provide up to a two-year warranty on capital equipment upon initial sale, and we establish a reserve for warranty repairs based on historical warranty repair costs incurred. Provisions for warranty obligations, which are included in cost of sales, are provided for at the time of shipment. We expect our cost of sales to increase in absolute dollars for the foreseeable future primarily as, and to the extent, our revenue grows, partially offset by lower unit product costs, though it may fluctuate from period to period.

We calculate gross margin as gross profit divided by revenue. Our gross margin has been and will continue to be affected by a variety of factors, primarily, product mix and the resulting average selling prices, production volumes, manufacturing costs and product yields, and the implementation of cost reduction strategies. Our software gross margin is generally higher than our product gross margin. As a result of these factors, we expect gross margin may fluctuate from period to period. We are engaged in various efforts to improve our gross margin by reducing unit product costs to the extent our production volumes increase, as well as through product design improvements, reducing material costs through negotiations with suppliers and optimizing the manufacturing process and reducing the costs to service our installed base.

Selling, general and administrative ("SG&A") expenses consist primarily of personnel compensation, including stock-based compensation, related to selling, marketing, professional education, administration, finance, information technology, legal, and human resource functions. SG&A expenses also include commissions, training, travel expenses, promotional activities, conferences, trade shows, professional services fees, audit fees, legal fees, insurance costs and general corporate expenses including allocated facilities-related expenses. We expect our SG&A expenses to increase in absolute dollars for the foreseeable future as we expand our

commercial infrastructure and incur additional fees associated with operating as a public company, including legal, accounting, insurance, exchange listing and SEC compliance, investor relations, and other administrative and professional services expenses, though it may fluctuate from period to period. However, over time, we expect our SG&A expenses to decrease as a percentage of revenue.

Research and development ("R&D") expenses consist primarily of costs incurred for proprietary R&D programs, and include costs of product engineering, product development, regulatory affairs, consulting services, materials, and depreciation, as well as other costs associated with products and technologies being developed. These expenses include employee and non-employee compensation, including stock-based compensation, supplies, materials, consulting, related travel expenses and facilities expenses. We expect our R&D expenses to moderate in absolute dollars for the foreseeable future as we continue to develop, enhance, and commercialize new products and technologies. However, we expect our R&D expenses as a percentage of revenue to vary over time depending on the level and timing of initiating new product development efforts.

Other (expense) income, net, consists primarily of interest expense under our outstanding term loan and investment income.

The following table shows our results of operations for the six months ended June 30, 2023 and 2022, together with the dollar and percentage change in those items:

The following table shows our breakdown of revenue for the three and six months ended ~~March 31,~~June 30, 2023 and 2022, together with the dollar and percentage change in those items:

Total revenue increased ~~$1.7~~$0.5 million, or ~~19%~~5%, and $2.2 million, or 11%, for the three months and six months ended ~~March 31,~~June 30, 2023, respectively, from the comparable ~~period~~periods in the prior ~~year,~~ year.

Product revenue increased ~~$1.5~~$0.3 million, or ~~20%~~4%, for the three months ended ~~March 31,~~June 30, 2023 compared to the prior year period, which was primarily driven by ~~growth in sales volumes in PIs, as well as~~ an increase in the average selling price of PIs of approximately 17%, partially offset by ~~approximately 9%.~~a decrease in Consoles sales volumes. For the three months ended ~~March 31,~~June 30, 2023, we generated ~~$2.0~~ $2.2 million, $5.6 million and ~~$5.7~~ $1.0 million from the sale of GentleWave ~~consoles~~Consoles, PIs and ~~PIs,~~other products, respectively, compared ~~to $2.1~~to$2.7 million, $4.8 million and ~~$4.3~~$0.9 million, respectively, for the three months ended ~~March 31,~~June 30, 2022.

Software revenue increased $0.2 million, or ~~12%~~8%, for the three months ended ~~March 31,~~June 30, 2023 compared to the prior year period, which was primarily due to a higher number of customer subscriptions.

23Product revenue increased $1.8 million, or 11%, for the six months ended June 30, 2023 compared to the prior year period, which was primarily driven by an increase in the average selling price of PIs of approximately 13%, as well as an increase in PI sales volumes of approximately 10%, partially offset by a decrease in Consoles sales volume. For the six months ended June 30, 2023, we generated $4.2 million and $11.3 million from the sale of GentleWave Consoles and PIs, respectively, compared to $4.8 million and $9.1 million, respectively, for the six months ended June 30, 2022.

Software revenue increased $0.4 million, or 10%, for the six months ended June 30, 2023 compared to the prior year period, which was primarily due to a higher number of customer subscriptions.

Cost of sales increased ~~$0.6~~$2.0 million, or 9%24%, and $2.6 million, or 17%, for the three and six months ended ~~March 31,~~June 30, 2023, respectively, from the comparable ~~period~~periods in the prior year. The increase was primarily ~~attributable~~driven by a $1.7 million charge due to ~~higher console~~reduced sales volumes of our legacy GentleWave Console ("Gen3"), and a $1.2 million charge due to phasing out our legacy procedure instruments, the molar and pre-molar as we move to the CleanFlow procedure instruments. These charges were partially offset by lower cost of CleanFlow PIs on per unit basis ~~which was partially offset by a favorable manufacturing absorption of approximately $0.3 million attributable~~as compared to ~~improved operating leverage.~~our legacy PI products. There were no significant changes in the Software segment cost of sales.

Gross margin ~~increased 6%~~decreased 14% and 4% for the three months and six months ended ~~March 31,~~June 30, 2023, respectively, from the comparable ~~period~~periods in the prior year, primarily due to the aforementioned charges to cost of sales and higher console cost on per unit basis, partially offset by higher PI average selling price and ~~improved operating leverage, which was partially offset by higher console~~lower PI cost on per unit basis.

SG&A expenses increased ~~$2.7~~$1.9 million or ~~22%~~15%, and $4.6 million, or 19%, for the three and six months ended ~~March 31,~~June 30, 2023, respectively, from the comparable period in the prior ~~year,~~year. The increase was primarily driven by changes in our Product segment due to ~~approximately $1.5 million~~ higher employee-related compensation and benefit expenses of approximately $0.7 million for the three months period and approximately $2.5 million in the six month period, including stock-based compensation, and recruiting expenses, as a result of the expansion of our commercial infrastructure and our general and administrative functions. There were no significant changes in the Software segment selling, general and administrative expenses.

R&D expenses decreased ~~$1.4~~$0.7 million or ~~28%~~18% and $2.1 million, or 23%, for the three and six months ended ~~March 31,~~June 30, 2023, respectively, from the comparable period in the prior year, which was primarily driven by lower ~~headcount and lower~~ spending on product development and outside services in the Product ~~segment.~~segment, as well as lower headcount. There were no significant changes in any major components of the R&D expenses in the Software segment as described in the Components of Our Results of Operations above.

Total other expense net for the three and six months ended ~~March 31,~~June 30, 2023 decreased compared to the prior year periods, mainly due to interest income from our short-term investments.

We have incurred significant operating losses and negative cash flows from operations since our inception, and we anticipate that we will continue to incur net losses for the next several years.

On September 27, 2022, we completed a private placement (the "Private Placement"), issuing an aggregate of approximately 23.0 million shares of our common stock at a purchase price of $0.95 per share and pre-funded warrants to purchase an aggregate of 43.3 million shares of our common stock at a purchase price of $0.949 per pre-funded warrant. The pre-funded warrants have an exercise price of $0.001 per share of common stock, are immediately exercisable and will remain exercisable until exercised in full. The aggregate net proceeds from the Private Placement, after deducting placement agent fees and other offering expenses, were $59.0 million.

As of ~~March 31,~~June 30, 2023, we had cash and cash equivalents and short-term investments of ~~$74.9~~$65.9 million, an accumulated deficit of ~~$384.5~~$402.2 million, and $40.0 million in principal outstanding under our term loan facility. For the three and six months ended ~~March 31,~~June 30, 2023 and 2022, our net losses from operations were ~~$15.3~~$33.1 million and ~~$15.5~~$30.7 million, respectively, and our net cash used in operating activities was ~~$17.0~~$26.3 million and ~~$18.0~~$31.5 million, respectively.

On March 10, 2023, the California Department of Financial Protection and Innovation shut down Silicon Valley Bank (SVB) due to liquidity concerns and appointed the Federal Deposit Insurance Corporation (FDIC) as receiver. On ~~Sunday, March 12, 2023, the U.S. Treasury Department, Federal Reserve and FDIC announced that all bank depositors would have access to their money starting Monday, March 13, 2023. On~~ March, 27, 2023, SVB began operating as a division of First Citizens Bank. As of ~~March 31,~~June 30, 2023, ~~the Company~~we held approximately ~~$0.6~~$0.9 million in operating accounts at SVB. ~~The Company’s~~Our remaining cash and cash equivalents and short-term investments, consisting of money market funds, high-grade corporate securities, and U.S. government backed securities, reside in custodial accounts held by U.S. Bank. There has been no disruption to the Company's operations.

We expect our operating expenses to increase for the foreseeable future as we continue to invest in expanding our sales and marketing infrastructure programs to both drive and support anticipated sales growth and product development. In addition, we expect our general and administrative expenses to increase for the foreseeable future as we hire personnel and expand our infrastructure to both drive and support the anticipated growth in our organization. We will also incur additional expenses as we increase the size of our administrative function to support the growth of our business and operations as a public company. The timing and amount of our operating expenditures will depend on many factors, including:

Our unaudited condensed consolidated financial statements included elsewhere in this Quarterly Report have been prepared assuming we will continue to operate as a going concern, which contemplates the realization of assets and settlement of liabilities in the normal course of business, and do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classifications of liabilities that may result from uncertainty related to our ability to continue as a going concern. Based upon our current operating plan, we believe that our cash and cash equivalents and short-term investments will be sufficient to meet our capital requirements and fund our operations through at least the next 12 months from the date of this Quarterly Report. If our actual operating expenses significantly exceed our operating plan or our debt financing arrangements become unavailable because certain borrowing requirements are not met (see Note 9 of our unaudited condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q), we may have to significantly delay or scale back our operations to reduce working capital requirements, and substantial uncertainty would exist with respect to our ability to continue as a going concern. In addition, we would prioritize necessary and appropriate steps to enable the continued operations of the business and preservation of the value of our assets beyond the next 12 months, including but not limited to, actions such as reducing personnel-related costs and delaying or curtailing certain of our commercial efforts, development activities and other discretionary expenditures that are within our control. These reductions in expenditures, if required, may have an adverse impact on our ability to achieve certain of our planned objectives in fiscal year 2023.

We have based this estimate on estimates and assumptions that may prove to be wrong, and we may need to utilize additional available capital resources or seek additional financing opportunistically. Our ability to continue as a going concern is dependent upon our ability to successfully secure sources of financing and ultimately achieve profitable operations. If our existing capital resources are insufficient to satisfy our liquidity requirements, we may seek to sell additional public or private equity or debt securities or obtain an additional credit facility. The sale of equity or convertible debt securities may result in dilution to our stockholders and, in the case of

preferred equity securities or convertible debt, those securities could provide for rights, preferences or privileges senior to those of our common stock. Debt financing, if available, may involve covenants restricting our operations or our ability to incur additional debt. Any debt financing or additional equity that we raise may contain terms that are not favorable to us or our stockholders. If we raise additional capital through collaboration agreements, licensing or divestiture arrangements, or marketing and distribution arrangements, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product or grant licenses that may not be favorable to us. Additional financing may not be available at all, or in amounts or on terms unacceptable to us.

On April 6, 2022, we entered into Amendment No. 1 (the “First Amendment”) to the Amended and Restated Credit Agreement and Guaranty (the “Perceptive Loan Agreement”) with Perceptive Credit Holdings III, LP (“Perceptive”). The First Amendment extended the borrowing deadline for the first tranche of $10.0 million of delayed-draw term loans from December 31, 2021 to September 30, 2022, ~~subject to our having generated at least $36.0 million in revenue for the 12 consecutive month period most recently ended prior to the borrowing date. The First Amendment~~and also extended the borrowing deadline for the second tranche of $10.0 million delayed-draw term loans from March 31, 2022 to June 30, 2023, subject to (i) our having generated at least $46.0 million in revenue for the 12 consecutive month period most recently ended prior to the borrowing date; and (ii) our closing market capitalization being at least $100.0 million on each trading day of the period of 15 consecutive trading days ending on the business day the borrowing notice for the tranche is delivered to Perceptive.2023. We borrowed the extended first tranche of $10.0 million onin July ~~29,~~ 2022, ~~and received~~receiving net proceeds of $9.9 ~~million.~~

As a condition to entering into the First Amendment, on April 6, 2022, we also amended the warrants previously issued to Perceptive and certain of its affiliates to purchase an aggregate of 304,105 shares of our common stock. Such warrants were amended solely to reduce the exercise price of the warrants to $12.00 per share. In August 2022, a portion of these warrants representing 153,421 shares were transferred to a third party and its affiliates.

For the ~~three~~six months ended ~~March 31,~~June 30, 2023 and 2022, the interest rate for amounts borrowed under the Perceptive Loan Agreement, as amended, was the greater of the 1-month LIBOR and 2.00% plus the applicable margin of 9.25%. On January 13, 2023, we entered into Amendment No. 2 (the "Second Amendment") to the Perceptive Loan Agreement, as amended, to replace the existing benchmark rate from the one-month LIBOR with a one-month Secured Overnight Financing Rate ("SOFR"). All other terms remain unchanged on the original agreement.

In connection with entering into the Perceptive Loan Agreement, we also entered into an amended and restated security agreement and granted a security interest in substantially all of our assets. We are permitted to make voluntary prepayments, subject to a scaled prepayment premium that ranges from 7.0% to 1.0% of the aggregate principal amount outstanding on such prepayment date for prepayments made after August 23, 2022 and before August 23, 2025. No prepayment premium is required for payments made after August 23, 2025.

The Perceptive Loan Agreement, as amended, includes financial covenants that require usthe Company to (i) maintain, at all times, a minimum aggregate balance of $3.0 million in cash in one or more controlled accounts, and (ii) satisfy certain minimum revenue thresholds, measured for the 12 consecutive ~~month period~~12-month periods ending on each calendar quarter-end until June 30, 2026. These thresholds progressively increase over time, ~~and range~~ranging from $26.4 million for the consecutive 12-month ~~period ended~~periods ending September 30, 2021 to $95.3 million for the consecutive 12-month ~~period ended~~periods ending June 30, 2026. Specifically, the minimum revenue thresholds for the consecutive 12-months period ending on June 30, 2024 and September 30, 2024, are $47.2 million and $52.0 million, respectively. Failure to satisfy these financial covenants would constitute an event of default under the ~~Perceptive Loan Agreement,~~agreement, as amended.

The Perceptive Loan Agreement, as amended, contains events of default, including, without limitation, events of default upon: (i) failure to make a payment pursuant to the terms of the agreement; (ii) violation of certain covenants; (iii) payment or other defaults on other indebtedness; (iv) material adverse change in the business or change in control; (v) insolvency; (vi) significant judgments; (vii) incorrectness of representations and warranties; (viii) regulatory matters; and (ix) failure by us to maintain a valid and perfected lien on the collateral securing the borrowing. In the event of an event of default, the lender may terminate its commitments and declare all amounts outstanding under the Perceptive Loan Agreement, as amended, immediately due and payable, together with accrued interest and all fees and other obligations. The amount of such repayment will include payment of any prepayment premium applicable due to the time of such payment. In addition, upon the occurrence and during the continuance of any event of default, the applicable margin will increase by 3.00% per annum to 12.25%.

As of ~~March 31,~~June 30, 2023, we had an aggregate principal balance of $40.0 million outstanding under the Perceptive Loan Agreement, as amended, and we were in compliance with all covenants and conditions under such agreement.

Net cash used in operating activities was ~~$17.0~~$26.3 million for the ~~three~~six months ended ~~March 31,~~June 30, 2023, primarily consisting of net loss of ~~$15.2~~$33.1 million as adjusted for non-cash items of ~~$2.3~~$4.7 million, ~~partially offset by~~as well as a net change in our net operating assets and liabilities of ~~$3.9~~$2.0 million. Non-cash items primarily consisted of ~~$0.8~~$2.0 million in depreciation and amortization and ~~$1.9~~$4.0 million in stock-based compensation. Changes in our net operating assets and liabilities year-over-year, was primarily due to a ~~$1.7~~$4.4 million cash receipts of ERC refund and $2.3 million decrease in inventory due to increase in ~~accrued expenses and other liabilities on payments to vendors and a $1.2 million~~inventory reserves for legacy products, partially offset by increase ~~in accrued compensation due to year-end bonus payout. Changes in our net operating assets and liabilities also resulted from changes~~ in accounts receivable, ~~inventory,~~ prepaid expenses, ~~and other assets~~accrued compensation and accounts payable attributable to timing of payment.

Net cash used in operating activities was ~~$18.0~~$31.5 million for the ~~three~~six months ended ~~March 31,~~June 30, 2022, primarily consisting of net loss of ~~$15.5~~$30.7 million as adjusted for non-cash items of ~~$2.0~~$4.5 million, ~~and~~partially offset by a net change in our net operating assets and liabilities of ~~$4.7~~$5.8 million. Non-cash items primarily consisted of ~~$0.7~~$1.6 million in depreciation and amortization and ~~$1.4~~$3.3 million in stock-based compensation. The change

in our net operating assets and liabilities was primarily due to a ~~$2.0~~$4.5 million increase in inventory held due to higher production and changes in prepaid expenses and other assets, accounts payable, accrued expenses and accrued compensation attributable to timing of payment.

Net cash provided by investing activities was ~~$12.0~~$21.1 million for the ~~three~~six months ended ~~March 31,~~June 30, 2023, as a result of proceeds from maturities of available-for-sale securities partially offset by the purchases of available-for-sale securities and property and equipment. Net cash used in investing activities was ~~$0.1~~$35.0 million for ~~each of~~ the ~~three~~six months ended ~~March 31,~~June 30, 2022, as a result of purchases ofavailable-for-sale securities and property and equipment.

Net cash used in financing activities for the ~~three~~six months ended ~~March 31,~~June 30, 2023 was immaterial. Net cash used by financing activities was $0.5 million for the ~~three~~six months ended ~~March 31,~~June 30, 2022, primarily resulting from the payment of the remainder of the IPO fees and contingent earnout.

Our management’s discussion and analysis of financial condition and results of operations is based on our condensed consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP"). The preparation of these condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, the revenue generated, and expenses incurred, and related disclosures, during the reporting periods. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions and any such differences may be material.

There were no material changes to our critical accounting policies or in the methodology used for estimates from those described in "Management's Discussion and Analysis of Financial Condition and Results of Operations" included in our Annual Report on Form 10-K filed with the SEC on March 8, 2023.

We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012 (the "JOBS Act"). As such, we are eligible for exemptions from various reporting requirements applicable to other public companies that are not emerging growth companies, including, but not limited to, presenting only two years of audited financial statements in addition to any required unaudited interim financial statements with correspondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure in this Quarterly Report on Form 10-Q, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation, and an exemption from the requirements to obtain a non-binding advisory vote on executive compensation or golden parachute arrangements. We have elected to take advantage of certain of the reduced disclosure obligations in this Quarterly Report on Form 10-Q and may elect to take advantage of other reduced reporting requirements in our future filings with the SEC. As a result, the information that we provide to our stockholders may be different than you might receive from other public reporting companies in which you hold equity interests.

In addition, the JOBS Act permits an “emerging growth company” such as us to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies. We have elected to avail ourselves of this exemption and, therefore, for new or revised accounting standards applicable to public companies, we may delay adopting new or revised accounting standards until those standards would otherwise apply to private companies.

We will remain an emerging growth company until the earliest of (1) the last day of our first fiscal year (a) following the fifth anniversary of our IPO, which closed on November 2, 2021, (b) in which we have total annual gross revenues of at least $1.07 billion or (c) in which we are deemed to be a large accelerated filer, as defined in Rule 12b-2 under the Exchange Act of 1934, as amended, which means the market value of our common stock that is held by non-affiliates exceeds $700 million as of the end of the second quarter of the prior fiscal year, and (2) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the prior three-year period.

We are also a “smaller reporting company” as defined in the Exchange Act. We may continue to be a smaller reporting company even after we no longer qualify as an emerging growth company. We may take advantage of certain of the scaled disclosures available to

smaller reporting companies and will be able to take advantage of these scaled disclosures for so long as our voting and non-voting common stock held by non-affiliates is less than $250 million measured on the last business day of our second fiscal quarter, or our annual revenue is less than $100 million during the most recently completed fiscal year and our voting and non-voting common stock held by non-affiliates is less than $700 million measured on the last business day of our second fiscal quarter.

See Note 2 to our unaudited condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q for additional information.

Our management, under the supervision and with the participation of our Chief Executive Officer (principal executive officer) and our Chief Financial Officer (principal financial officer), conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act of 1934, as amended, as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on that evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of ~~March 31,~~June 30, 2023.

There were no changes in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the quarter ended ~~March 31,~~June 30, 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Control systems, no matter how well conceived and operated, are designed to provide a reasonable, but not an absolute, level of assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have

been detected. Because of the inherent limitations in any control system, misstatements due to error or fraud may occur and not be detected.

From time to time, we may become involved in various claims and legal proceedings. Regardless of outcome, litigation and other legal and administrative proceedings can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors. We are currently not a party to any legal proceedings the outcome of which, if determined adversely to us, would individually or in the aggregate have a material adverse effect on our business, financial condition, and results of operations.

We have described under the heading “Risk Factors” in Part I, Item 1A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2022 risks and uncertainties that could cause our actual results of operations and financial condition to vary materially from past, or from anticipated future, results of operations and financial condition. These risks and uncertainties are not the only risks facing us. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also adversely affect our business, financial condition, results of operations or the market price of our common stock. Except as set forth below, there have been no material changes to the risk factors previously described in our 2022 Annual Report on Form 10-K.

We maintain cash deposits in excess of federally insured limits. Adverse developments affecting financial institutions, including bank failures, could adversely affect our liquidity and financial performance.

We regularly maintain domestic cash deposits in Federal Deposit Insurance Corporation (“FDIC”) insured banks, which exceed the FDIC insurance limits. Bank failures, events involving limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions, or concerns or rumors about such events, may lead to widespread demands for customer withdrawals and liquidity constraints that may result in market-wide liquidity problems. The failure of a bank, or other adverse conditions in the financial or credit markets impacting financial institutions at which we maintain balances, could adversely impact our liquidity and financial performance. There can be no assurance that our deposits in excess of the FDIC or other comparable insurance limits will be backstopped by the U.S. government in the future or that any bank or financial institution with which we do business will be able to obtain needed liquidity from other banks, government institutions or by acquisition in the event of a future failure or liquidity crisis.

Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned thereunto duly authorized.
