EXPLANATORY NOTE

As previously disclosed, on June 20, 2024, the Company’s common stock, $0.001 par value per share, trading symbol “BIOL”, was suspended from trading on the Nasdaq Stock Market LLC (the “Nasdaq”). On September 4, 2024, Nasdaq publicly announced that it had determined to commence proceedings to delist the Company’s common stock. Accordingly, the Company does not have any securities registered pursuant to Section 12(b) of the Securities Exchange Act of 1934 (the “Exchange Act”).

In addition, as previously disclosed, on October 1, 2024, BIOLASE, Inc. (the “Company”) and its direct domestic subsidiaries filed voluntary petitions for relief (the “Bankruptcy Petitions”) under chapter 11 of Title 11 of the United States Code (the “Bankruptcy Code”) in the United States Bankruptcy Court for the District of Delaware (the “Bankruptcy Court”). The Company will continue to operate its businesses as “debtors-in-possession” under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court. In addition, the Company filed a motion seeking approval for certain procedures relating to the marketing and auction (if necessary) of all or some of the Company’s assets, including approval of a “stalking horse” asset purchase agreement (the “Asset Purchase Agreement”) with Sonendo, Inc. (“Sonendo”), a Delaware corporation, pursuant to which Sonendo agreed to acquire substantially all of the Company’s assets (the “Transferred Assets”), and certain bidding procedures for the sale of the Transferred Assets and other assets (the "Bidding Procedures"). The Asset Purchase Agreement includes customary representations and warranties and various customary covenants under the circumstances that are subject to certain limitations, including, without limitation, a break-up fee, expense reimbursement and the right to designate executory contracts and unexpired leases to assume or reject.

On October 17, 2024, the Bankruptcy Court entered an order, which, among other things, approved the Bidding Procedures and the designation of Sonendo as the “stalking horse” bidder.

Unless specifically noted or the context clearly requires otherwise, all information set forth in this Quarterly Report on Form 10-Q relates to the Company as it existed as of September 30, 2024 and prior to the Company’s bankruptcy filing, and does not, and is not intended and should not be read to, reflect the business, financial condition, and results of operations of the Company after the bankruptcy filing, nor of any other entity, including any entity which may result from the bankruptcy proceedings.

NOTE 1—DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION

The Company

BIOLASE, Inc. (“BIOLASE” and, together with its consolidated subsidiaries, the “Company”) is a leading provider of advanced laser systems for the dental industry. The Company develops, manufactures, markets, and sells laser systems that provide significant benefits for dental practitioners and their patients. The Company’s proprietary systems allow dentists, periodontists, endodontists, pediatric dentists, oral surgeons, and other dental specialists to perform a broad range of minimally invasive dental procedures, including cosmetic, restorative, and complex surgical applications. The Company’s laser systems are designed to provide clinically superior results for many types of dental procedures compared to those achieved with drills, scalpels, and other conventional instruments. Potential patient benefits include less pain, fewer shots, faster healing, decreased fear and anxiety, and fewer appointments. Potential practitioner benefits include improved patient care and the ability to perform a higher volume and wider variety of procedures and generate more patient referrals.

Basis of Presentation

The unaudited condensed consolidated financial statements include the accounts of BIOLASE and its wholly-owned subsidiaries and have been prepared on a basis consistent with the December 31, 2023 audited consolidated financial statements and include all material adjustments, consisting of normal recurring adjustments and the elimination of all material intercompany transactions and balances, necessary to fairly present the information set forth therein. The unaudited condensed consolidated financial statements do not include all the footnotes, presentations, and disclosures normally required by accounting principles generally accepted in the United States of America (“GAAP”) for complete consolidated financial statements.

The unaudited condensed consolidated results of operations for the three and nine months ended September 30, 2024 are not necessarily indicative of the results for the full year. The December 31, 2023 condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes thereto for the year ended December 31, 2023 included in included in BIOLASE’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023 filed with the Securities and Exchange Commission (the “SEC”) on March 21, 2024 (the “2023 Form 10-K”).

Bankruptcy

As previously disclosed, on October 1, 2024 the Company and its direct domestic subsidiaries filed voluntary petitions for relief (the "Bankruptcy Petitions") under chapter 11 of Title 11 of the United States Code (the "Bankruptcy Code") in the United States Bankruptcy Court for the District of Delaware (the "Bankruptcy Court"). The Company will continue to operate its businesses as "debtors-in-possession" under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court. In addition, the Company filed a motion seeking approval for certain procedures relating to the marketing and auction (if necessary) of all or some of the Company's assets, including approval of an Asset Purchase Agreement (as defined below) and certain bidding procedures for the sale of the Transferred Assets (as defined below) and other assets (the "Bidding Procedures").

In addition, as previously disclosed, on September 30, 2024 the Company entered into a "stalking horse" asset purchase agreement (the "Asset Purchase Agreement") with Sonendo, Inc. ("Sonendo"), a Delaware corporation, pursuant to which Sonendo agreed to acquire substantially all of the Company's assets (the "Transferred Assets"). The acquisition by Sonendo pursuant to the Asset Purchase Agreement is subject to approval of the Bankruptcy Court following an auction, if necessary, to solicit higher or otherwise better bids. Other interested bidders are permitted to participate in the auction if they submit qualifying bids that are higher or otherwise better than the Asset Purchase Agreement.

Under the Asset Purchase Agreement, Sonendo agreed to acquire the Transferred Assets from the Company for (a) $14.0 million in cash paid at closing, subject to working capital adjustments; plus (b) assumption of certain Assumed Liabilities (as defined in the Asset Purchase Agreement); plus (c) the Delaware Litigation Settlement Value (as defined in the Asset Purchase Agreement). The Asset Purchase Agreement includes customary representations and warranties and various customary covenants under the circumstances that are subject to certain limitations, including, without limitation, a break-up fee, expense reimbursement and the right to designate executory contracts and unexpired leases to assume or reject.

On October 17, 2024, the Bankruptcy Court entered an order, which, among other things, approved the Bidding Procedures and the designation of Sonendo as the “stalking horse” bidder.

On November 4, 2024, the Company commenced the auction for the sale of the Transferred Assets (the “Auction”) pursuant to the Bidding Procedures. Following the completion of the Auction, the Company announced that the bid submitted by MegaGen Implant Co., LTD (“MegaGen”) for (a) $20.50 million in cash paid at closing, subject to working capital adjustments; plus (b) assumption of certain Assumed Liabilities, was the successful bid (the “Successful Bid”), and the bid submitted by Sonendo, which was increased from its prior bid to include (a) $19.95 million in cash paid at closing, subject to working capital adjustments; plus (b) assumption of certain Assumed Liabilities; plus (c) the Delaware Litigation Settlement Value, was the backup bid. The Successful Bid is subject to entry into definitive documentation between the Company and MegaGen. A hearing to consider approval of the results of the Auction is scheduled to take place on November 12, 2024.

The filing of the Bankruptcy Petitions constituted an event of default that accelerates the Company’s obligations under the following agreements: that certain Credit Agreement, dated November 9, 2018 (as amended, restated, supplemented or otherwise modified from time to time, the “Credit Agreement”) by and among the Company, the lender parties thereto (each a “Lender” and together, the “Lenders”), and SWK; and those certain standard loan documents required for an unsecured loan, dated as of May 22, 2020 (the “SBA Loan”) by and among the Company and the U.S. Small Business Administration (collectively, the “Financial Obligation Agreements”). The Financial Obligation Agreements provide that as a result of the Bankruptcy Petitions, all obligations to pay any debts, principal, interest, fees, expenses, and other amounts due thereunder shall be immediately due and payable. Any efforts to enforce such payment obligations under the Financial Obligation Agreements are automatically stayed as a result of the Bankruptcy Petitions, and the creditors’ rights of enforcement in respect of the Financial Obligation Agreements are subject to the applicable provisions of the Bankruptcy Code.

Prior to the filing of the Bankruptcy Petitions, the Company incurred $1.2 million in legal and financial advisory services as a result of receiving a Default Notice from our term loan lender, SWK Funding LLC, entering into a Forbearance Agreement, and preparing for the Bankruptcy Petitions. Due to these charges being incurred prior to the filing of the Bankruptcy Petitions, these expenses are presented as non-operating other loss on the Consolidated Statement of Operations and Comprehensive Loss.

DIP Financing

In connection with the Bankruptcy Petitions, the Company filed a motion seeking Bankruptcy Court approval of a debtor-in-possession ("DIP") financing on the terms set forth in that certain Terms and Conditions of Proposed Senior Secured, Super-Priority Debtor-in-Possession Credit Facility (the “DIP Term Sheet”), by and among the Company, as a borrower, and SWK Funding LLC ("SWK"), as DIP Lender and Agent. The DIP Term Sheet provides for a senior secured super-priority debtor-in-possession financing (the “DIP Financing”) in an aggregate amount of no less than $2.5 million. The DIP Financing will become available up to an amount of $1.43 million upon the satisfaction of customary conditions precedent thereto, including the entry of an order of the Bankruptcy Court approving the DIP Financing on an interim basis. Subject to entry of an order of the Bankruptcy Court approving the DIP Financing on a final basis, the DIP Obligations (as defined in the DIP Term Sheet) will include $2,500,000 advanced by SWK to the Debtors between September 3, 2024, and September 30, 2024.

The proceeds of the DIP Financing will be used by the Company to (a) fund, after application of all other available cash, post-petition operating expenses and working capital needs of the Company, including, but not limited to, those activities required to remain in, or return to, compliance with laws in accordance with 28 U.S.C. § 1930; (b) pay interest, fees and expenses to SWK in accordance with the DIP Term Sheet (whether or not such amounts are reflected in the Budget (as defined in the DIP Term Sheet)); (c) fund fees and expenses incurred in connection with the 363 Sale (as defined in the DIP Term Sheet); (d) pay permitted prepetition claims and adequate protection payments, if any; (e) pay Professional Fees (as defined in the DIP Term Sheet) provided for in the Budget, including funding of the Carve Out (as defined in the DIP Term Sheet); and (f) pay other costs and expenses of administration of the chapter 11 cases.

The maturity date of the loans made under the DIP Financing is the date that is one hundred-twenty (120) days after the Petition Date, or such later date to which SWK consents in writing.

Subject to certain exceptions, the DIP Financing will be secured by a first priority perfected priming security interest in all of the assets of the Company. The security interests and liens are subject only to certain carve-outs and certain permitted liens, as set forth in the DIP Term Sheet. The DIP Financing is subject to certain milestones, customary covenants, and events of default as set forth in the DIP Term Sheet.

Reverse Stock Split

At the annual meeting of stockholders held on May 2, 2024 (the "2024 Annual Meeting"), BIOLASE stockholders approved an amendment to BIOLASE’s Restated Certificate of Incorporation, as amended (the "Certificate of Incorporation"), to effect a reverse stock split of BIOLASE common stock, par value $0.001 per share (the “common stock”), at a ratio between one-for-two (1:2) and

one-for-fifty (1:50) with the ratio to be determined at the discretion of the Board. No official action has been taken to put this reverse stock into effect.

Liquidity and Management’s Plans - Going Concern

The Company incurred losses from operations and used cash in operating activities for the three and nine months ended September 30, 2024 and for the years ended December 31, 2023 and 2022. The Company’s recurring losses, level of cash used in operations, need for additional capital, along with uncertainties surrounding the Company’s ability to raise additional capital, especially in light of the fact that our common stock is no longer traded on the Nasdaq, which makes it harder to attract investors and limits the types of financings that can be conducted, and the filing of the Bankruptcy Petitions on October 1, 2024, raise substantial doubt about the Company’s ability to continue as a going concern. As such, the financial statements contain certain adjustments that are necessary as the Company is unable to continue as a going concern, which includes the reclassification of certain long term liabilities as current.

As of September 30, 2024, the Company had working capital deficit of approximately $11.4 million with the deficit primarily due to the SWK Loan (as defined below) that is set to mature in May 2025. The Company’s principal sources of liquidity as of September 30, 2024 consisted of approximately $3.4 million in cash and cash equivalents and $3.5 million of net accounts receivable. As of December 31, 2023, the Company had working capital of approximately $5.2 million, $6.6 million in cash and cash equivalents and $5.5 million of net accounts receivable. The decrease in cash and cash equivalents since December 31, 2023 was primarily due to a net loss of $10.7 million and principal payments on the Company's term loan of $0.9 million, partially offset by net proceeds of $5.8 million from the February 2024 public offering, a $2.5 million bridge loan from SWK as part of the Forbearance Agreement, $0.4 million in proceeds from the disposal of property, plant, and equipment, and $0.3 million in proceeds from the exercise of preferred share warrants.

Additional capital requirements may depend on many factors, including, among other things, the rate at which the Company’s business grows, demands for working capital, manufacturing capacity, any acquisitions that the Company may pursue, and the outcome of the Bankruptcy Petitions. The Company expects that it will be required to raise capital through either equity or debt offerings. The Company cannot provide assurance that it will be able to successfully enter into any such equity or debt financings in the future or that the required capital would be available on acceptable terms, if at all, or that any such financing activity would not be dilutive to its stockholders.

NOTE 2—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates

The preparation of these condensed consolidated financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect amounts reported in the condensed consolidated financial statements and the accompanying notes. Significant estimates in these condensed consolidated financial statements include allowances on accounts receivable, inventory, and deferred taxes, as well as estimates for accrued warranty expenses, goodwill and the ability of goodwill to be realized, revenue deferrals, effects of stock-based compensation and warrants, contingent liabilities, the provision or benefit for income taxes, and preferred stock. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may differ materially from those estimates.

Critical Accounting Policies

Information with respect to the Company’s critical accounting policies, which management believes could have the most significant effect on the Company’s reported results and require subjective or complex judgments by management, is discussed in the Company’s 2023 audited financial statements included in the 2023 Form 10-K. Management believes that there have been no significant changes during the nine months ended September 30, 2024 in the Company’s critical accounting policies from those disclosed in the Company’s 2023 audited financial statements included in the 2023 Form 10-K.

Fair Value of Financial Instruments

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants in the principal market (or, if none exists, the most advantageous market) for the specific asset or liability at the measurement date (referred to as the “exit price”). The fair value is based on assumptions that market participants would use, including a consideration of non-performance risk. Under the accounting guidance for fair value hierarchy, there are three levels of measurement inputs. Level 1 inputs are quoted prices in active markets for identical assets or liabilities. Level 2 inputs are observable, either directly or indirectly. Level 3 inputs are unobservable due to little or no corroborating market data.

The Company’s financial instruments, consisting of cash, cash equivalents, accounts receivable, accounts payable, accrued liabilities, warrants, and the SWK Loan (as defined below) as discussed in Note 9 – Debt, approximate fair value because of the relative short maturity of these items and the market interest rates the Company could obtain.

Concentration of Credit Risk, Interest Rate Risk and Foreign Currency Exchange Rate

Financial instruments which potentially expose the Company to a concentration of credit risk consist principally of cash and cash equivalents, and trade accounts receivable. The Company maintains its cash and cash equivalents with established commercial banks. At times, balances may exceed federally insured limits. To minimize the risk associated with trade accounts receivable, management performs ongoing credit evaluations of customers’ financial condition and maintains relationships with the Company’s customers that allow management to monitor current changes in business operations so the Company can respond as needed. The Company does not, generally, require customers to provide collateral before it sells them its products. However, the Company has required certain distributors to make prepayments for significant purchases of its products.

Substantially all of the Company’s revenue is denominated in U.S. dollars, including sales to international distributors. Only a small portion of its revenue and expenses is denominated in foreign currencies, principally the Euro and Indian Rupee. The Company’s foreign currency expenditures primarily consist of the cost of maintaining offices, consulting services, and employee-related costs. During the three and nine months ended September 30, 2024 and 2023, respectively, the Company did not enter into any hedging contracts. Future fluctuations in the value of the U.S. dollar may affect the price competitiveness of the Company’s products outside the U.S.

Recent Accounting Pronouncements

Changes to GAAP are established by the Financial Accounting Standards Board (“FASB”) in the form of accounting standards updates (“ASUs”) to the FASB’s Accounting Standards Codification (“ASC”).

The Company considers the applicability and impact of all ASUs. ASUs not listed below were assessed and determined not to be applicable or are expected to have minimal impact on the Company’s consolidated financial position and results of operations.

Recently Issued Accounting Standards

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740) - Improvements to Income Tax Disclosures, to require enhanced income tax disclosures to provide information to assess how an entity’s operations and related tax risks, tax planning, and operational opportunities affect its tax rate and prospects for future cash flows. The amendments in this update provide that a business entity disclose (1) a tabular income tax rate reconciliation, using both percentages and amounts, (2) separate disclosure of any individual reconciling items that are equal to or greater than 5% of the amount computed by multiplying the income (loss) from continuing operations before income taxes by the applicable statutory income tax rate, and disaggregation of certain items that are significant and (3) amount of income taxes paid (net of refunds received) disaggregated by federal, state and foreign jurisdictions, including separate disclosure of any individual jurisdictions greater than 5% of total income taxes paid. These amendments are effective for the Company for annual periods in 2025, applied prospectively, with early adoption and retrospective application permitted. The Company intends to adopt the amendments in this update prospectively in 2025. The impact of the adoption of the amendments in this update is not expected to be material to the Company’s consolidated financial position and results of operations, since the amendments require only enhancement of existing income tax disclosures in the footnotes to the Company’s consolidated financial statements.

NOTE 3—REVENUE RECOGNITION

Contracts with Customers

Revenue for sales of products and services is derived from contracts with customers. The products and services promised in customer contracts include delivery of laser systems, imaging systems, and consumables as well as certain ancillary services such as training and extended warranties. Contracts with each customer generally state the terms of the sale, including the description, quantity and price of each product or service. Payment terms are stated in the contract and vary according to the arrangement. Because the customer typically agrees to a stated rate and price in the contract that does not vary over the life of the contract, the Company’s contracts do not contain variable consideration. The Company establishes a provision for estimated warranty expenses.

Performance Obligations

At contract inception, the Company assesses the products and services promised in its contracts with customers. The Company then identifies performance obligations to transfer distinct products or services to the customers. In order to identify performance

obligations, the Company considers all of the products or services promised in contracts regardless of whether they are explicitly stated or are implied by customary business practices.

Revenue from products and services transferred to customers at a single point in time accounted for 88% and 86% of net revenue for the three and nine months ended September 30, 2024, respectively, and 87% and 89% for the three and nine months ended September 30, 2023, respectively. The majority of the Company’s revenue recognized at a point in time is for the sale of laser systems and consumables. Revenue from these contracts is recognized when the customer is able to direct the use of and obtain substantially all of the benefits from the product which generally coincides with title transfer during the shipping process.

Revenue from services transferred to customers over time accounted for 12% and 14% of net revenue for the three and nine months ended September 30, 2024, respectively, and 13% and 11% for the three and nine months ended September 30, 2023, respectively. The majority of the Company’s revenue that is recognized over time relates to product training and extended warranties. Deferred revenue attributable to undelivered elements, which primarily consists of product training, totaled approximately $0.5 million as of September 30, 2024 and $0.4 million as of December 31, 2023.

Transaction Price Allocation

The transaction price for a contract is allocated to each distinct performance obligation and recognized as revenue when, or as, each performance obligation is satisfied. For contracts with multiple performance obligations, the Company allocates the contract’s transaction price to each performance obligation using the best estimate of the standalone selling price of each distinct good or service in a contract. The primary method used to estimate standalone selling price is the observable price when the good or service is sold separately in similar circumstances and to similar customers.

Significant Judgments

Revenue is recorded for extended warranties over time as the customer benefits from the warranty coverage. This revenue will be recognized equally throughout the contract period as the customer receives benefits from the Company's promise to provide such services. Revenue is recorded for product training when the customer attends a training program or upon the expiration of the obligation, which is generally after six months.

The Company also has contracts that include both the product sales and product training as performance obligations. In those cases, the Company records revenue for product sales at the point in time when the product has been shipped. The customer obtains control of the product when it is shipped, as all shipments are made FOB shipping point, and after the customer selects its shipping method and pays all shipping costs and insurance. The Company has concluded that control is transferred to the customer upon shipment.

Accounts Receivable

Accounts receivable are stated at estimated net realizable value. The allowance for doubtful accounts is based on an analysis of customer accounts and the Company’s historical experience with accounts receivable write-offs.

Contract Liabilities

The Company performs its obligations under a contract with a customer by transferring products and/or services in exchange for consideration from the customer. The Company typically invoices its customers as soon as control of an asset is transferred and a receivable for the Company is established. The Company, however, recognizes a contract liability when a customer prepays for goods and/or services, and the Company has not transferred control of the goods and/or services. The opening and closing balances of the Company’s contract liabilities are as follows (in thousands):


	September 30,			December 31,
	2024			2023
Undelivered elements (training and installation)	$	511		$	449
Extended warranty contracts		1,935			2,259
Total deferred revenue		2,446			2,708
Less: long-term portion of deferred revenue		(220	)		(256	)
Deferred revenue — current	$	2,226		$	2,452

The balance of contract assets was immaterial as the Company did not have a significant amount of uninvoiced receivables at September 30, 2024 and December 31, 2023.

The amount of revenue recognized during the nine months ended September 30, 2024 and 2023 that was included in the opening contract liability balance related to undelivered elements was $0.4 million and $0.3 million, respectively. The amounts related to extended warranty contracts was $1.8 million and $1.5 million for the nine months ended September 30, 2024 and 2023, respectively.

Disaggregation of Revenue

The Company disaggregates revenue from contracts with customers into geographical regions and by the timing of when goods and services are transferred. The Company determined that disaggregating revenue into these categories depicts how the nature, amount, timing and uncertainty of revenue and cash flows are affected by regional economic factors.

The Company’s revenues related to the following geographic areas were as follows (in thousands):


	Three Months Ended				Nine Months Ended
	September 30,				September 30,
	2024		2023		2024		2023
United States	$	8,246	$	7,298	$	23,176	$	24,797
International		2,604		3,623		9,360		10,877
Net revenue	$	10,850	$	10,921	$	32,536	$	35,674

Information regarding revenues disaggregated by the timing of when goods and services are transferred is as follows (in thousands):


	Three Months Ended				Nine Months Ended
	September 30,				September 30,
	2024		2023		2024		2023
Revenue recognized over time	$	1,257	$	1,366	$	4,457	$	3,950

Net revenue	$	10,850	$	10,921	$	32,536	$	35,674

The Company’s sales by end market were as follows (in thousands):


	Three Months Ended				Nine Months Ended
	September 30,				September 30,
	2024		2023		2024		2023
End-customer	$	8,246	$	7,298	$	23,176	$	24,797
Distributors		2,604		3,623		9,360		10,877
Net revenue	$	10,850	$	10,921	$	32,536	$	35,674

Shipping and Handling Costs and Revenues

Shipping and freight costs are treated as fulfillment costs. For shipments to end-customers, the customer bears the shipping and freight costs and has control of the product upon shipment. For shipments to distributors, the distributor bears the shipping and freight costs, including insurance, tariffs and other import/export costs.

NOTE 4—CONVERTIBLE REDEEMABLE PREFERRED STOCK AND STOCKHOLDERS’ EQUITY (DEFICIT)

The Board, without further stockholder authorization, may authorize the issuance from time to time of up to 1,000,000 shares of the Company’s preferred stock. Of the 1,000,000 shares of preferred stock, as of September 30, 2024, 370,000 shares were designated as Series H, par value $0.001 per share, 160,000 shares were designated as Series J, par value $0.001 per share, and 125,000 shares were designated as Series I, par value $0.001 per share.

Preferred Stock

Series J Preferred Stock

On September 13, 2023, the Company consummated the sale of 75,000 Units (the "Units") with each Unit consisting of (A) one share of BIOLASE Series J Convertible Redeemable Preferred Stock, par value $0.001 per share and a stated value equal to $100.00 (the “Series J Convertible Preferred Stock”), and (B) one warrant (the “Series J Warrants”) to purchase one-half of one (0.50) share of Series J Convertible Preferred Stock, at a price to the public of $60.00 per Unit, less underwriting discounts and commissions. The

public offering price of $60.00 per Unit reflects the issuance of the Series J Convertible Preferred Stock with an original issue discount of 40%. The Company filed a registration statement on Form S-1 in September 2023, which registered the Units, the Series J Convertible Preferred Stock, the Series J Warrants and the shares of Series J Convertible Preferred Stock and common stock underlying such securities and additional shares of Series J Convertible Preferred Stock that will be issued, if and when the Board declares such dividends, as paid in-kind dividends (“PIK dividends”) at a rate of 20% per annum and the shares of Common Stock issuable upon conversion of the Series J Convertible Preferred Stock issued as PIK dividends. The registration statement was declared effective on September 13, 2023 and the offering closed on September 18, 2023. Each Warrant has an exercise price of $30.00 per share, is exercisable for one-half of one (0.5) share of Series J Convertible Preferred Stock, is immediately exercisable and will expire one (1) year from the date of issuance.

Each share of Series J Convertible Preferred Stock is convertible at the option of the holder at any time into the number of shares of common stock determined by dividing the $100.00 stated value per share by a conversion price of $3.26. Each outstanding share of Series J Convertible Preferred Stock is mandatorily redeemable by the Company in cash on September 13, 2024 (the "Series J Maturity Date").

Gross proceeds from the offering were $4.5 million before broker fees and related expenses of approximately $1.0 million. In accordance with applicable accounting standards, the $4.5 million gross proceeds were allocated to the Series J Convertible Preferred Stock and the Series J Warrants in the amount of $3.5 million and $1.0 million, respectively. The allocation was based on the fair value of the Series J Warrants of $1.0 million as of the commitment date, with the residual proceeds of $3.5 million allocated to the Series J Convertible Preferred Stock. Net proceeds allocated to the Series J Convertible Preferred Stock and Series J Warrants was $2.7 million and $0.8 million respectively.

The Series J Convertible Preferred stock was classified as mezzanine equity on the consolidated balance sheet as they are contingently redeemable prior to the Series J Maturity Date and the conversion from preferred shares to shares of common stock is at the option of the holder at any time before the Series J Maturity Date. The Series J Warrants were classified as accrued liabilities on the consolidated balance sheet as the warrants are convertible into preferred shares, which are mandatorily redeemable in cash upon the Series J Maturity Date if they are not converted to shares of common stock before such date.

The Series J Convertible Preferred Stock was issued at a discount with the total redemption value of the Series J Convertible Preferred Shares and PIK Dividends of $10.3 million. The redemption value in excess of the net proceeds received allocated to the Series J Convertible Preferred Shares was $7.6 million and was recognized as a decrease in additional paid-in-capital at the commitment date. Upon conversion of Series J Warrants to Series J Convertible Preferred shares, the value of the Series J Convertible Preferred Stock issued is the stated value per share plus the PIK dividend. The redemption value in excess of the net proceeds received from the exercise of warrants and the fair value of such warrants is recognized as a decrease in additional paid-in-capital at the conversion date.

On July 16, 2024, the Company issued an aggregate of 3,190,476 shares of its common stock, par value $0.001 per share, in exchange for (i) 2,546 shares of the Company’s Series J Convertible Redeemable Preferred Stock, par value $0.001 per share (the "Series J Preferred Stock"), and (ii) 8,000 Series J Preferred Warrants to purchase 4,000 shares of Series J Preferred Stock, pursuant to the terms of that certain Exchange Agreement (the "Exchange Agreement") entered into on July 16, 2024 by the Company and the investor named therein.

The Company issued common stock to the investor in reliance on the exemption from the registration requirements of the Securities Act of 1933, as amended, afforded by Section 3(a)(9) thereof. The shares of Common Stock issued upon exchange of the Series J Preferred Stock and Series J Preferred Warrants have not been registered under the Securities Act and may not be offered or sold in the United States in the absence of an effective registration statement or exemption from the registration requirements. No proceeds have been or will be received and no commissions have been or will be paid by the Company in connection with the exchange described herein.

The elimination of the Series J Preferred Warrants and the Series J Convertible Redeemable Preferred Stock were presented as a reduction in accrued liabilities and mezzanine equity in the amounts of $0.1 million and $0.3 million, respectively, with a corresponding increase to additional paid-in-capital.

On September 18, 2024, all 52,040 unexercised Series J Warrants expired, and all 15,805 unconverted Series J Convertible Preferred Stock were to be mandatorily redeemed at their stated value of $100.00. However, due to the pending bankruptcy filing, the Company was unable to complete this mandatory redemption in the amount of $1.6 million in cash to holders of these Series J Convertible Preferred Stock. The expiration of the Series J Warrants was presented as a $0.5 million decrease in accrued liabilities with a corresponding gain on warrants. The $1.6 million mandatory redemption amount for unsettled Series J Convertible Preferred Stock was presented as a decrease in mezzanine equity and an increase in accrued liabilities.

From the date of sale through the expiration date, 14,960 of the Series J Warrants were exercised for 7,480 shares of Series J Convertible Preferred Stock, 6,836 shares of Series J Convertible Preferred Stock were issued as part of PIK dividends, 2,546 shares of Series J Convertible Preferred Stock were exchanged for shares of common stock as part of the Exchange Agreement, and 70,965 shares of Series J Convertible Preferred Stock were converted to approximately 2.2 million shares of common stock. During the nine months ended September 30, 2024, 9,000 of the Series J Warrants were exercised for 4,500 Series J Convertible Preferred Stock, 4,500 shares of the Series J Convertible Preferred Stock were converted to common stock, 3,745 Series J Convertible Preferred Stock were issued as part of PIK dividends, and 2,546 shares of Series J Convertible Preferred Stock were exchanged for shares of common stock as part of the Exchange Agreement. As of September 30, 2024, there were no Series J Convertible Preferred Stock or Series J Warrants outstanding.

The mezzanine classified Series J Convertible Preferred Stock were presented at their maximum redemption value that included accretion related to the PIK dividends.

Series I Preferred Stock

On June 5, 2023, the Board declared a dividend of one one-thousandth of a share of Series I Preferred Stock, par value $0.001 per share ("Series I Preferred Stock"), for each share of common stock outstanding as of June 16, 2023 (as calculated on a pre 2023 Reverse Stock Split basis). The certificate of designation for the Series I Preferred Stock provided that all shares of Series I Preferred Stock not present in person or by proxy at any meeting of stockholders held to vote on the 2023 Reverse Stock Split immediately prior to the opening of the polls at such meeting would be automatically redeemed (the “Series I Initial Redemption”) and that any outstanding shares of Series I Preferred Stock that have not been redeemed pursuant to the Series I Initial Redemption would be redeemed in whole, but not in part, (i) if and when ordered by the Board or (ii) automatically upon the effectiveness of the amendment to the Certificate of Incorporation effecting the 2023 Reverse Stock Split that was subject to the vote (the "Series I Subsequent Redemption").

Series H Preferred Stock

On May 24, 2023, the Company consummated the sale of 175,000 Units (the "Units") with each Unit consisting of (A) one share of BIOLASE Series H Convertible Redeemable Preferred Stock, par value $0.001 per share and a stated value equal to $50.00 (the “Series H Convertible Preferred Stock”), and (B) one warrant (the “Series H Warrants”) to purchase one-half of one (0.50) share of Series H Convertible Preferred Stock, at a price to the public of $26.00 per Unit, less underwriting discounts and commissions. The public offering price of $26.00 per Unit reflects the issuance of the Series H Convertible Preferred Stock with an original issue discount of 48%. The Company filed a registration statement on Form S-1 in May 2023, which registered the Units, the Series H Convertible Preferred Stock, the Series H Warrants and the shares of Series H Convertible Preferred Stock and common stock underlying such securities and additional shares of Series H Convertible Preferred Stock that will be issued, if and when the Board declares such dividends, as paid in-kind dividends (“PIK dividends”) at a rate of 20% and the shares of Common Stock issuable upon conversion of the Series H Convertible Preferred Stock issued as PIK dividends. The registration statement was declared effective on May 24, 2023 and the offering closed on May 26, 2023. Each Series H Warrant has an exercise price of $13.00 per share, is exercisable for one-half of one (0.5) share of Series H Convertible Preferred Stock, is immediately exercisable and will expire two (2) years from the date of issuance.

Each share of Series H Convertible Preferred Stock is convertible at the option of the holder at any time into the number of shares of common stock determined by dividing the $50.00 stated value per share by a conversion price of $13.98 (as adjusted for the 2023 Reverse Stock Split). Each outstanding share of Series H Convertible Preferred Stock is mandatorily redeemable by the Company in cash on May 24, 2025 (the "Series H Maturity Date").

Gross proceeds from the offering were $4.6 million before broker fees and related expenses of approximately $0.9 million. In accordance with applicable accounting standards, the $4.6 million gross proceeds were allocated to the Series H Convertible Preferred Stock and the Series H Warrants in the amount of $3.4 million and $1.2 million, respectively. The allocation was based on the fair value of the Series H Warrants of $1.2 million as of the commitment date, with the residual proceeds of $3.4 million allocated to the Series H Convertible Preferred Stock. Net proceeds allocated to the Series H Convertible Preferred Stock and Series H Warrants was $2.7 million and $1.0 million, respectively.

The Series H Convertible Preferred Stock was classified as mezzanine equity on the consolidated balance sheet as they are contingently redeemable prior to the Series H Maturity Date and the conversion from preferred shares to shares of common stock is at the option of the holder at any time before the Series H Maturity Date. The Series H Warrants were classified as accrued liabilities on the consolidated balance sheet as the warrants are convertible into preferred shares, which are mandatorily redeemable in cash upon the Series H Maturity Date if they are not converted to shares of common stock before such date.

The Series H Convertible Preferred Stock was issued at a discount with the total redemption value of the Series H Convertible Preferred Shares and PIK Dividends of $10.5 million. The redemption value in excess of the net proceeds received allocated to the Series H Convertible Preferred Stock was $7.8 million and was recognized as a decrease in additional paid-in-capital at the commitment date. Upon conversion of Series H Warrants to Series H Convertible Preferred Stock, the value of the Series H Convertible Preferred Stock issued is the stated value per share plus the PIK dividend. The redemption value in excess of the net proceeds received from the exercise of warrants and the fair value of such warrants is recognized as a decrease in additional paid-in-capital at the conversion date.

As of September 30, 2024, 40,000 of the Series H Warrants have been exercised for 20,000 shares of Series H Convertible Preferred Stock, 1,923 shares of Series H Convertible Preferred Stock have been issued as part of PIK dividends, and 190,000 shares of Series H Convertible Preferred Stock have been converted to approximately 0.7 million shares of common stock. There have been no exercises of Series H Warrants or conversion of Series H Convertible Preferred Stock during the nine months ended September 30, 2024. As of September 30, 2024, there are 6,923 Series H Convertible Preferred Stock outstanding.

The mezzanine classified Series H Convertible Preferred Stock are presented at their maximum redemption value that includes accretion related to the PIK dividends.

The Units were sold at the public offering price of $0.44 per Unit and the Pre-Funded Units were sold at the public offering price of $0.439 per Pre-Funded Unit. The Company received gross proceeds of approximately $7.0 million, before deducting underwriting discounts and commissions, estimated offering expenses, and before the exercise of warrants.

Based on the terms and conditions of the February 2024 Offering, the Company determined that liability classification was appropriate for the Class A Common Warrants and Class B Common Warrants and recognized the gross proceeds from the issuance allocated to the warrants in excess of par of $3.7 million in accrued liabilities and expensed issuance costs of $0.6 million allocated to the warrants. The Class A Common Warrants were valued using either a long stock position plus a long call position or a Black-Scholes call option model which was deemed appropriate given the warrants can be exercised via the stated exercise price, or an alternative cashless exercise for 0.95 shares per warrant, with a fair value that approximates 95% of the current stock price. The unobservable inputs utilized in determining the fair value of the Class A Common Warrants, which are categorized as a Level 3 instrument, is the volatility rate of 85%. The Class B Common Warrants were valued using a Monte Carlo simulation. The unobservable inputs utilized in determining the fair value of the Class B Common Warrants, which are categorized as a Level 3 instrument, is the volatility rate of 85% as well as the probability of a future financing event.

Phantom Awards and Stock Appreciation Rights

In 2021, 2022 and 2023 the Company granted phantom RSUs which were granted in lieu of stock-settled RSUs historically granted for leadership bonuses and non-employee director service. The phantom RSUs had either time-based or performance-based vesting conditions and a cash settlement date in 2024 with the Company's option to settle the award in common stock at the sole discretion of the Board. At inception, these phantom RSUs were included as a component of long-term liability on the consolidated balance sheet and were not considered stock-based compensation due to the cash-settlement feature of the award and the then current limitation on the number of remaining shares authorized for issuance. In 2022, as a result of the Reverse Stock Split, the phantom awards were reclassed to equity and included as a component of additional paid-in-capital in the amount of $0.1 million, with a portion remaining as a component of long-term liability on the consolidated balance sheet due to certain guaranteed minimums, and the expense subsequent to the remeasurement date considered stock-based compensation. As of December 31, 2023, approximately 2,113 of these phantom RSUs were cancelled due to non-achievement of performance metrics, and during the three months ended March 31, 2024 an additional 828 units were cancelled due to non-achievement. In March 2024, the Board approved settlement of the remaining 291 phantom RSUs with time-based vesting conditions in quarterly cash installments through April 2025 in the aggregate amount of $0.6 million. As of September 30, 2024, $0.5 million was included in accrued liabilities on the consolidated balance sheet. As of December 31, 2023, $0.5 million was included in accrued liabilities and $0.2 million was included in additional paid-in-capital on the consolidated balance sheet

As of September 30, 2024, there are approximately 236 outstanding SARs granted in 2021 in lieu of stock-settled RSUs historically granted for non-employee director service. Upon exercise, the SARs could be settled in cash with the Company's option to settle in common stock at the sole discretion of the Board. These SARs were fully vested in 2022. No expense was recognized during the nine months ended September 30, 2024 and 2023, respectively.

Net Loss Per Share – Basic and Diluted

Basic net loss per share is computed by dividing net loss attributable to common stockholders by the weighted-average number of shares of BIOLASE common stock outstanding for the period. In computing diluted net loss per share, the weighted average number of shares of common stock outstanding is adjusted to reflect the effect of potentially dilutive securities. Net loss is adjusted for any deemed dividends to preferred stockholders to compute net income attributable to common stockholders.

The 8,205,000 February 2024 Pre-Funded Warrants and 779,940 December 2023 Pre-Funded Warrants were included in the calculation of basic and diluted loss per share as of the date of issuance for the nine months ended September 30, 2024 as the underlying warrant shares are issuable for little or no cash consideration. The 114,035 January 2023 Pre-Funded Warrants were included in the calculation of basic and diluted loss per share as of the date of issuance for the three and nine months ended September 30, 2023 as the underlying warrant shares are issuable for little or no cash consideration.

Outstanding stock options, restricted stock units, preferred shares, and warrants to purchase approximately 23,010,024 and 2,537,031 shares were not included in the calculation of diluted net loss per share amounts for the periods ended September 30, 2024 and September 30, 2023, respectively, as their effect would have been anti-dilutive.

NOTE 7—INTANGIBLE ASSETS AND GOODWILL

The Company conducted its annual impairment test of goodwill as of September 30, 2024 and determined that there was no impairment. The Company filed the Bankruptcy Petitions on October 1, 2024, and signed the Asset Purchase Agreement on September 30, 2024. The Asset Purchase Agreement was in the amount of $14.0 million which was in excess of the Company’s carrying value, indicating no impairment to its Goodwill. On November 4, 2024, the Company commenced the auction for the sale of the Transferred Assets and received a winning bid of $20.50 million in cash from MegaGen with a back-up bid of $19.95 million from Sonendo.

The Company also tests its intangible assets and goodwill between the annual impairment tests if events occur or circumstances change that would more likely than not reduce the fair value of the Company or its assets below their carrying amounts. For intangible assets subject to amortization, the Company performs its impairment test when indicators, such as reductions in demand or significant economic slowdowns, are present. During the fourth quarter ended December 31, 2023, due to the sustained decrease in the stock price of the common stock decreasing the implied fair value of the business, the Company performed a quantitative assessment of impairment over goodwill and determined that there was no impairment to the Company's goodwill. Goodwill was valued using an equally weighted income approach and market approach. The unobservable inputs utilized in determining the fair value of the goodwill, which is categorized as a Level 3 instrument, are the discount rate of 19.1% and various revenue growth rates utilized in the financial forecast of future cash flows.

As of September 30, 2024 and December 31, 2023, the Company had goodwill (indefinite life) of $2.9 million. As of September 30, 2024 and December 31, 2023, all intangible assets subject to amortization have been fully amortized and there was no amortization expense recognized during the three and nine months ended September 30, 2024 and 2023.

Term Loan

On November 9, 2018, the Company entered into that certain five-year secured Credit Agreement with SWK, pursuant to which the Company has outstanding principal of $13.3 million (“SWK Loan”) as of September 30, 2024. In addition, pursuant to the Credit Agreement, the Company is required to pay certain exit fees totaling $1.4 million upon loan termination which are recorded as a debt premium. The Company’s obligations under the Credit Agreement are secured by substantially all of the Company’s assets. Under the terms of the Credit Agreement and subsequent amendments as discussed in the Company’s 2023 Form 10-K, repayment of the SWK Loan is interest-only for the first two years, paid quarterly with the option to extend the interest-only period. Principal repayments were to begin in the first quarter of 2021. On June 30, 2022 the Company entered into the ninth amendment to the Credit Agreement (the "Ninth Amendment"), which extended the interest-only period by two quarters from May 2023 to November 2023. On December 30, 2022, the Company entered into the tenth amendment to the Credit Agreement, which lowered the required minimum consolidated unencumbered liquid assets from $3 million to $2.5 million and removed the conditional minimum last twelve months aggregate revenue and EBITDA as of the end of the twelve-month period ended December 31, 2022. On November 15, 2023, the Company entered into the Eleventh Amendment to Credit Agreement, which reduced the principal amortization payments due on November 15, 2023 and February 15, 2024 to $165,000, reduced the required minimum consolidated unencumbered liquid assets to $1.5 million through and including December 30, 2023 and to $2.5 million thereafter, and reduced the required minimum consolidated unencumbered liquid assets to $3.5 million as of the last day of any fiscal quarter beginning with the period ending March 31, 2024. In connection with the Ninth Amendment, the Company prepaid $1.0 million of the outstanding loan balance. Principal repayments began in November 2023 and are $0.7 million quarterly after February 2024 until the SWK Loan matures in May 2025. The loan bears interest of 9% plus LIBOR with a floor of 1.25%, or another index that approximates LIBOR as close as possible if and when LIBOR no longer exists.

In May 2024 all remaining long-term balances related to the SWK Loan were reclassified to current liabilities due to the loan maturity date of May 31, 2025.

The Company was scheduled to make its quarterly principal and interest payment of approximately $1.2 million on August 15, 2024. However, the Company was unable to make this payment. On August 22, 2024 SWK notified the Company of an alleged event of default under the Credit Agreement, and extended the August payment date to August 30, 2024.

On August 31, 2024, the Company and SWK entered into a Forbearance Agreement (the "Forbearance Agreement"). Under the terms of the Forbearance Agreement, SWK agreed: (a) not to accelerate or cause the acceleration of the maturity of the loans or other obligations or to otherwise enforce payment of the obligations of the Company in full under the Credit Agreement and the loan

documents, and (b) not to exercise any other default or event of default related rights and remedies available to SWK against the Company under any loan document or applicable law with respect to any obligation owed under the loan documents. Upon termination or expiration of the period (the “Forbearance Period”), SWK shall be entitled to exercise any of its respective rights and remedies under the Forbearance Agreement, the other loan documents, or applicable law, including, without limitation, the right to enforce any and all of the liens on, and security interests in, the collateral described in the loan documents, without further notice, demand, notice of intent to accelerate, notice of acceleration, presentment, protest or other formalities of any kind. The Forbearance Period terminated upon the Company's filing of chapter 11 bankruptcy on October 1, 2024. The Company also agreed to pay the reasonable fees and expenses of SWK in connection with entering into the Forbearance Agreement and the other loan documents.

In addition, the Forbearance Agreement provided that during the Forbearance Period, provided no Forbearance Default has occurred and certain other conditions are met, Agent and Lenders agreed to fund term loans, in an aggregate amount not to exceed $2,500,000 (the bridge loan) and in accordance with the terms of the Forbearance Agreement, to pay operating expenses of the Company, including, without limitation, payments with respect to out of pocket legal or restructuring expenses of the Company, Agent or Lenders.

Under the Forbearance Agreement, the Company also agreed to, among other things, prepare for and file a bankruptcy case under Chapter 11 of the Bankruptcy Code in the United States Bankruptcy Court for the District of Delaware for the sale of the Company’s assets. In connection with the sale process the Company agreed to comply with certain process milestones which require, among other things, the entry into a purchase and sale agreement with a so-called “stalking horse bidder” by September 30, 2024, filing a bankruptcy case by October 1, 2024, and closing the sale by November 15, 2024. All of the milestones and the entire sale process are subject to bankruptcy court approval and the milestones that occur after the commencement of the Company’s bankruptcy case are subject to change by the bankruptcy court to accommodate its own schedule.

The Forbearance Agreement further provides that the Company shall request that Lenders provide a debtor-in-possession loan (the “DIP Loan”) to the Company in the Chapter 11 case, on terms acceptable to the Agent and Lenders. The Agent is to condition the provision of the DIP Loan to the Company on the $2,500,000 bridge loan described in the preceding paragraph itself being considered a debtor-in-possession loan and being “rolled-up” in the DIP Loan to be provided to the Company in the Chapter 11 case pursuant to the final order that will be entered in the Chapter 11 case by the bankruptcy court approving the DIP Loan.

During the Forbearance Period, the Company had agreed, among other things: (a) not to grant or pay any executive bonuses without the consent of the Agent, (b) to provide the Agent with notice of any employee resignation, (c) not to make any expenditure for the business to consumer laser product line, (d) to comply with the cash flow forecasted budget it created in connection with entering into the Forbearance Agreement and to keep its aggregate expenditures within an agreed upon budget variance of 10% in the case of expenditures, (e) to provide weekly reporting of actual results compared to the budget, (f) not to suffer the appointment of a receiver, trustee, custodian or similar fiduciary, (g) to pay all reasonable fees and expenses incurred by the Agent and Lenders in connection with the Forbearance Agreement and the loan documents, including the reasonable and documented fees and expenses of the Agent’s and Lenders’ external counsel, and (h) not to pay or make any distributions on account of subordinated debt of the Company and its subsidiaries or agree to any amendments to any subordinated debt documents without the Agent’s consent.

As of September 30, 2024, the Company was in compliance with the terms of the Forbearance Agreement.

EIDL Loan

On May 22, 2020, the Company executed the standard loan documents required for securing a loan (the “EIDL Loan”) from the Small Business Administration (the "SBA") under its Economic Injury Disaster Loan assistance program in light of the impact of the COVID-19 pandemic on the Company’s business. The principal amount of the EIDL Loan is $150,000, with the proceeds to be used for working capital purposes. Interest on the EIDL Loan accrues at the rate of 3.75% per annum, and installment payments, including principal and interest, are due monthly beginning in July 2021 and are payable through July 2050. In April 2021, the SBA announced that it was extending the first payment due date for all loans until 2022, or 24 months from the loan execution date. In March 2022, the SBA announced that it was extending the first payment due date for all loans an additional six months, or 30 months from the loan execution date. The Company began making payments on the EIDL Loan starting in November 2022. Fixed payments are first applied to any accrued interest.

Due to the Forbearance Agreement and subsequent Bankruptcy Petition, the $150,000 EIDL Loan balance was classified as a current liability as of September 30, 2024

NOTE 10—LEASES

The Company enters into operating leases primarily for real estate, office equipment, and fleet vehicles. Lease terms generally range from one to five years, and often include options to renew for one year.

No individual customer represented more than 10% of the Company’s revenue for the three and nine months ended September 30, 2024 or 2023.

The Company maintains its cash and cash equivalents in money market investment accounts with established commercial banks. Such cash deposits periodically exceed the Federal Deposit Insurance Corporation insured limit.

As of September 30, 2024, no individual customer represented more than 10% of the Company's accounts receivable. As of December 31, 2023 accounts receivable from one customer totaled approximately 11% of total gross accounts receivable which has been partially received in 2024 and partially reserved for uncollectibility as of September 30, 2024.

The Company currently purchases certain key components of its products from single suppliers. Although there are a limited number of manufacturers of these key components, management believes that other suppliers could provide similar key components on comparable terms. A change in suppliers, however, could cause delays in manufacturing and a possible loss of sales, which could adversely affect the Company’s business, results of operations and financial condition.

NOTE 13—INCOME TAXES

The Company accounts for income taxes under the asset and liability method, whereby deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Management evaluates the need to establish a valuation allowance for deferred tax assets based upon the amount of existing temporary differences, the period in which they are expected to be recovered, and expected levels of taxable income. A valuation allowance to reduce deferred tax assets is established when it is “more likely than not” that some or all of the deferred tax assets will not be realized. Based on the Company’s net losses in prior years, management has determined that a full valuation allowance against the Company’s net deferred tax assets is appropriate.

Accounting for uncertainty in income taxes prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return and provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. The Company has elected to classify interest and penalties as a component of its income tax provision. With respect to the liability for unrecognized tax benefits, including related estimates of penalties and interest, the Company did not record a liability for unrecognized tax benefits for the three and nine months ended September 30, 2024 and 2023. The Company does not expect any changes to its unrecognized tax benefit for the next 12 months that would materially impact its consolidated financial statements.

During the three and nine months ended September 30, 2024, the Company recorded an income tax provision of $12,000 and $51,000 resulting in an effective tax rate of 0.8% and 0.5%, respectively. During the three and nine months ended September 30, 2023, the Company recorded an income tax provision of $15,000 and $46,000, respectively, resulting in an effective tax rate of 0.3%. The income tax provisions for the three and nine months ended September 30, 2024 and 2023 were calculated using the discrete year-to-date method. The effective tax rate differs from the statutory tax rate of 21% primarily due to the existence of valuation allowances against net deferred tax assets and current liabilities resulting from the estimated state income tax liabilities and foreign tax liability.

NOTE 14—SUBSEQUENT EVENTS

The Company has evaluated all events or transactions that occurred after September 30, 2024 through November 7, 2024, which is the date that the condensed consolidated financial statements were available to be issued. During this period, there were no material subsequent events requiring recognition or disclosure, other than those described below.

Bankruptcy

As previously disclosed, on October 1, 2024 the Company and its direct domestic subsidiaries filed voluntary petitions for relief (the "Bankruptcy Petitions") under chapter 11 of Title 11 of the United States Code (the "Bankruptcy Code") in the United States Bankruptcy Court for the District of Delaware (the "Bankruptcy Court"). The Company will continue to operate its businesses as "debtors-in-possession" under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court. In addition, the Company filed a motion seeking approval for certain procedures relating to the marketing and auction (if necessary) of all or some of the Company's assets, including approval of an Asset Purchase Agreement (as previously defined) and certain bidding procedures for the sale of the Transferred Assets (as previously defined) and other assets (the "Bidding Procedures"). The Asset Purchase Agreement includes customary representations and warranties and various customary covenants under the circumstances that are subject to certain limitations, including, without limitation, a break-up fee, expense reimbursement and the right to designate executory contracts and unexpired leases to assume or reject.

On October 17, 2024, the Bankruptcy Court entered an order, which, among other things, approved the Bidding Procedures and the designation of Sonendo as the “stalking horse” bidder.

OTCQB Delisting

On October 2, 2024, the Company received notice from OTC Markets Group, Inc. (the “OTC”) that the Company no longer meets the Standards for Continued Eligibility for OTCQB as per the OTCQB Standards, Section 2.3(5).

Overview

BIOLASE, Inc. (“BIOLASE” and, together with its consolidated subsidiaries, the “Company,” “we,” “our” or “us”) is a leading provider of advanced laser systems for the dental industry. We develop, manufacture, market, and sell laser systems that provide significant benefits for dental practitioners and their patients. Our proprietary systems allow dentists, periodontists, endodontists, pediatric dentists, oral surgeons, and other dental specialists to perform a broad range of minimally invasive dental procedures, including cosmetic, restorative, and complex surgical applications. Our laser systems are designed to provide clinically superior results for many types of dental procedures compared to those achieved with drills, scalpels, and other conventional instruments. Potential patient benefits include less pain, fewer shots, faster healing, decreased fear and anxiety, and fewer appointments. Potential practitioner benefits include improved patient care and the ability to perform a higher volume, and wider variety of procedures.

We offer two categories of laser system products: Waterlase (all-tissue) systems and diode (soft-tissue) systems. Our flagship brand, the Waterlase, uses a patented combination of water and laser energy and is FDA cleared for over 80 clinical indications to perform most procedures currently performed using drills, scalpels, and other traditional dental instruments for cutting soft and hard tissue. For example, Waterlase safely debrides implants without damaging or significantly affecting surface temperature and is an effective, safe solution for preserving sick implants. In addition, Waterlase disinfects root canals more efficiently than some traditional chemical methods. We offer our diode laser systems to perform soft tissue, pain therapy, and cosmetic procedures, including teeth whitening. As of December 31, 2023, we maintained approximately 241 active and 21 pending United States and international patents, with the majority relating to our Waterlase technology. Our patent portfolio is regularly evaluated, and we strategically prioritize our core patents to ensure optimal intellectual property coverage while minimizing annual maintenance fees. From 1998 through December 31, 2023, we have sold over 47,700 laser systems in over 80 countries around the world, and we believe that Waterlase iPlus is the world’s best-selling all-tissue dental laser. Since 1998, we have been the global leading innovator, manufacturer, and marketer of dental laser systems.

We also manufacture and sell consumable products and accessories for our laser systems. Our Waterlase and diode systems use disposable laser tips of differing sizes and shapes depending on the procedure being performed. We also market flexible fibers and hand pieces that dental practitioners replace at some point after initially purchasing laser systems. For our Epic line of diode laser systems, we sell teeth whitening gel kits. During the quarter ended September 30, 2024, the sale of lasers accounted for approximately 54% of our total sales, and consumables, accessories, and services accounted for approximately 46% of our total sales.

We currently operate in a single reportable business segment. We had net revenues of $10.9 million and $32.5 million for the three and nine months ended September 30, 2024, respectively and net revenues of $10.9 million and $35.7 million for the three and nine months ended September 30, 2023, respectively. We had net losses of $1.4 million and $10.7 million for the three and nine months ended September 30, 2024, respectively and $4.6 million and $15.3 million for the three and nine months ended September 30, 2023. We had total assets of $27.2 million as of September 30, 2024 and $35.1 million as of December 31, 2023.

Business and Outlook

Our Waterlase systems precisely cut hard tissue, bone, and soft tissue with minimal or no damage to surrounding tissue and dental structures. Our diode systems, which include the Epic system, are designed to complement our Waterlase systems, and are used only in soft tissue procedures, pain therapy, hygiene, and cosmetic applications, including teeth whitening. The diode systems, together with our Waterlase systems, offer practitioners a broad product line with a range of features and price points.

Due to the limitations associated with traditional and alternative dental instruments, we believe there is a large market opportunity for all-tissue dental laser systems that provide superior clinical outcomes, reduce the need to use anesthesia, help reduce trauma, pain, and discomfort associated with dental procedures, and increase patient acceptance for treatment protocols.

Our strategy is to increase awareness and demand for (i) our products among dental practitioners by educating dental practitioners and patients about the clinical benefits of our product suite and (ii) our laser systems among patients by educating patients about the clinical benefits of the Waterlase and diode systems. An important goal of ours is to increase consumables revenue by selling more single-use accessories used by dental practitioners when performing procedures using our dental laser systems. In the short term, we are striving for operating excellence through lean enterprise initiatives, with a specific focus on our sales strategy and cash flow management, coupled with optimizing our engineering capabilities to develop innovative new products.

We also seek to create value through innovation and leveraging existing technologies into adjacent medical applications. We plan to expand our product line and clinical applications by developing enhancements and transformational innovations, including new clinical solutions for dental applications and for other adjacent medical applications. In particular, we believe that our existing technologies can provide significant improvements over existing standards of care in fields including ophthalmology, otolaryngology, orthopedics, podiatry, pain management, aesthetics/dermatology, veterinary, and consumer products. We plan to continue to explore potential collaborations to apply our proprietary laser technologies with expanded FDA-cleared indications to other medical applications in the future.

The Company experienced revenue decline of 1% and 9% for the three and nine months ended September 30, 2024, respectively, compared to the same period in 2023.

Recent Developments

Bankruptcy and Asset Purchase Agreement

On October 17, 2024, the Bankruptcy Court entered an order, which, among other things, approved the Bidding Procedures and the designation of Sonendo as the “stalking horse” bidder.

The filing of the Bankruptcy Petitions constituted an event of default that accelerates the Company’s obligations under the following agreements: that certain Credit Agreement by and among the Company, the lender parties thereto (each a “Lender” and together, the “Lenders”), and SWK; and those certain standard loan documents required for an unsecured loan, dated as of May 22, 2020 (the “SBA Loan”) by and among the Company and the U.S. Small Business Administration (collectively, the “Financial Obligation Agreements”). The Financial Obligation Agreements provide that as a result of the Bankruptcy Petitions, all obligations to pay any debts, principal, interest, fees, expenses, and other amounts due thereunder shall be immediately due and payable. Any efforts to enforce such payment obligations under the Financial Obligation Agreements are automatically stayed as a result of the Bankruptcy Petitions, and the creditors’ rights of enforcement in respect of the Financial Obligation Agreements are subject to the applicable provisions of the Bankruptcy Code.

DIP Financing

As previously disclosed, in connection with the Bankruptcy Petitions, the Company filed a motion seeking Bankruptcy Court approval of a debtor-in-possession ("DIP") financing on the terms set forth in that certain Terms and Conditions of Proposed Senior Secured, Super-Priority Debtor-in-Possession Credit Facility (the “DIP Term Sheet”), by and among the Company, as a borrower, and SWK, as DIP Lender and Agent. The DIP Term Sheet provides for a senior secured super-priority debtor-in-possession financing (the “DIP Financing”) in an aggregate amount of no less than $2.5 million. The DIP Financing will become available up to an amount of $1.43 million upon the satisfaction of customary conditions precedent thereto, including the entry of an order of the Bankruptcy Court approving the DIP Financing on an interim basis. Subject to entry of an order of the Bankruptcy Court approving the DIP Financing on a final basis, the DIP Obligations (as defined in the DIP Term Sheet) will include $2,500,000 advanced by SWK to the Debtors between September 3, 2024, and September 30, 2024.

in, or return to, compliance with laws in accordance with 28 U.S.C. § 1930; (b) pay interest, fees and expenses to SWK in accordance with the DIP Term Sheet (whether or not such amounts are reflected in the Budget (as defined in the DIP Term Sheet)); (c) fund fees and expenses incurred in connection with the 363 Sale (as defined in the DIP Term Sheet); (d) pay permitted prepetition claims and adequate protection payments, if any; (e) pay Professional Fees (as defined in the DIP Term Sheet) provided for in the Budget, including funding of the Carve Out (as defined in the DIP Term Sheet); and (f) pay other costs and expenses of administration of the chapter 11 cases.

The maturity date of the loans made under the DIP Financing is the date that is one hundred-twenty (120) days after the Petition Date, or such later date to which SWK consents in writing.

Forbearance Agreement

As previously disclosed, on August 31, 2024, the Company and SWK entered into a Forbearance Agreement (the "Forbearance Agreement"). Under the terms of the Forbearance Agreement, SWK agreed: (a) not to accelerate or cause the acceleration of the maturity of the loans or other obligations or to otherwise enforce payment of the obligations of the Company in full under the Credit Agreement and the loan documents, and (b) not to exercise any other default or event of default related rights and remedies available to SWK against the Company under any loan document or applicable law with respect to any obligation owed under the loan documents. Upon termination or expiration of the period (the “Forbearance Period”), SWK shall be entitled to exercise any of its respective rights and remedies under the Forbearance Agreement, the other loan documents, or applicable law, including, without limitation, the right to enforce any and all of the liens on, and security interests in, the collateral described in the loan documents, without further notice, demand, notice of intent to accelerate, notice of acceleration, presentment, protest or other formalities of any kind. The Forbearance Period terminated upon the Company's filing of chapter 11 bankruptcy on October 1, 2024. The Company also agreed to pay the reasonable fees and expenses of SWK in connection with entering into the Forbearance Agreement and the other loan documents.

During the Forbearance Period, SWK loaned the Company an additional $2.5 million payable upon loan maturity. In connection with the bankruptcy filing, the scheduled quarterly principal and interest payments in August 2024 and November 2024 were delayed for payment upon loan maturity.

Non-GAAP Disclosure

In addition to the financial information prepared in conformity with GAAP, we provide certain historical non-GAAP financial information. Management believes that these non-GAAP financial measures assist investors in making comparisons of period-to-period operating results and that, in some respects, are indicative of our ongoing core performance.

Management believes that the presentation of this non-GAAP financial information provides investors with greater transparency and facilitates comparison of operating results across a broad spectrum of companies with varying capital structures, compensation strategies, derivative instruments, and amortization methods, which provides a more complete understanding of our financial performance, competitive position, and prospects for the future. However, the non-GAAP financial measures presented in this Form 10-Q have certain limitations in that they do not reflect all of the costs associated with the operations of our business as determined in accordance with GAAP. Therefore, investors should consider non-GAAP financial measures in addition to, and not as a substitute for, or as superior to, measures of financial performance prepared in accordance with GAAP. Further, the non-GAAP financial measures presented by us may be different from similarly named non-GAAP financial measures used by other companies.

Adjusted EBITDA

Management uses Adjusted EBITDA in its evaluation of our core results of operations and trends between fiscal periods and believes that these measures are important components of its internal performance measurement process. Adjusted EBITDA is defined as net loss before interest, taxes, depreciation, stock-based and other non-cash compensation, severance expense, change in allowance for doubtful accounts, increase in inventory reserves, stock warrant issuance costs, and loss on warrants. Management uses Adjusted EBITDA in its evaluation of our core results of operations and trends between fiscal periods and believes that these measures are important components of its internal performance measurement process.

Typically, we experience fluctuations in revenue from quarter to quarter due to seasonality. Revenue in the first quarter typically is lower than average, and revenue in the fourth quarter typically is higher than average, due to the buying patterns of dental practitioners. We believe that this trend exists because a significant number of dentists purchase their capital equipment towards the end of the calendar year in order to maximize their practice earnings while seeking to minimize their taxes. They often use certain tax incentives, such as accelerated depreciation methods for purchasing capital equipment, as part of their year-end tax planning. In addition, revenue in the third quarter may be affected by vacation patterns which can cause revenue to be flat or lower than in the

second quarter of the year. Our historical seasonal fluctuations may also be impacted by sales promotions used by large dental distributors that encourage end-of-quarter and end-of-year buying in our industry.

Net revenue decreased by $0.1 million, or 1%, during the three months ended September 30, 2024 as compared to the same period in 2023 primarily due to a decrease in laser systems sales from the impact of the current macro-economic environment causing extended sales cycles, which includes elevated interest rates, partially offset by an increase in consumables and other revenue from improved utilization of installed laser systems. Net revenue was $10.9 million during the three months ended September 30, 2024 and 2023.

Cost of Revenue and Gross Profit: The following table summarizes our unaudited cost of revenue and gross profit for the three months ended September 30, 2024 and 2023, as well as the amount of change and percentage of change (dollars in thousands):


	Three Months Ended
	September 30,								Amount			Percent
	2024				2023				Change			Change
Net revenue	$	10,850	100.0	%	$	10,921	100.0	%	$	(71	)		(0.7	)%
Cost of revenue		6,468	59.6	%		7,175	65.7	%		(707	)		(9.9	)%
Gross profit	$	4,382	40.4	%	$	3,746	34.3	%	$	636			17.0	%

Gross profit as a percentage of net revenue typically fluctuates with product and regional mix, selling prices, product costs and revenue levels. Gross profit for the three months ended September 30, 2024, was $4.4 million, or 40% of net revenue, which was higher than a gross profit of $3.7 million, or 34% of net revenue, for the same period in 2023. The 6% increase in gross profit as a percentage of net revenue when compared to the same period in 2023 reflects an improvement in supply chain issues that resulted in a decrease to warranty reserves, service expense and freight charges during the three months ended September 30, 2024.

Operating Expenses: The following table summarizes our unaudited operating expenses (including as a percentage of net revenue) for the three months ended September 30, 2024 and 2023, as well as the amount of change and percentage of change (dollars in thousands):


	Three Months Ended
	September 30,								Amount			Percent
	2024				2023				Change			Change
Sales and marketing	$	2,877	26.5	%	$	3,402	31.2	%	$	(525	)		(15.4	)%
General and administrative		1,283	11.8	%		2,679	24.5	%		(1,396	)		(52.1	)%
Engineering and development		917	8.5	%		1,362	12.5	%		(445	)		(32.7	)%
Total operating expenses	$	5,077	46.8	%	$	7,443	68.2	%	$	(2,366	)		(31.8	)%

Sales and Marketing Expense. Sales and marketing expenses during the three months ended September 30, 2024 decreased by $0.5 million, or 15%, as compared to the same period in 2023. This decrease is primarily due to lower compensation expenses from the impact of our cost savings initiatives implemented during the first quarter of 2024, as well as a decrease in commissions and bonus incentives when compared to the same period in 2023.

General and Administrative Expense. General and administrative expenses during the three months ended September 30, 2024 decreased by $1.4 million, or 52%, compared to the same period in 2023. This decrease is due to the reversal of expenses for annual bonus incentives during the three months ended September 30, 2024 from not achieving financial performance targets, as well as less legal, consulting and investor relations activity from our special shareholder meeting held during the third quarter of 2023 to obtain approval for our reverse stock split that did not reoccur in the third quarter of 2024.

Engineering and Development Expense. Engineering and development expenses during the three months ended September 30, 2024 decreased by $0.4 million, or 33%, compared to the same period in 2023. This decrease is primarily due to lower compensation expenses from the impact of our cost savings initiatives implemented during the first quarter of 2024, as well as the reversal of expenses for annual bonus incentives during the three months ended September 30, 2024 from not achieving financial performance targets.

Non-Operating Income (Loss)

Loss on Foreign Currency Transactions. We realized an approximately $0.1 million loss on foreign currency transactions during the three months ended September 30, 2024 compared to an approximately $0.3 million loss on foreign currency transactions during the three months ended September 30, 2023, primarily due to exchange rate fluctuations between the U.S. dollar and Euro, as well as other foreign currencies.

Interest Expense, Net. Interest expense was $0.6 million during the three months ended September 30, 2024 which was consistent with the three months ended September 30, 2023.

Other Income (Expense), Net. Other Expense for the three months ended September 30, 2024 was $47 thousand and relates to $1.2 million in legal and financial advisory services incurred as a result of receiving a Default Notice from our term loan lender, SWK Funding LLC, and entering into a Forbearance Agreement. Under the Forbearance Agreement, the Company agreed to, among other things, prepare for and file a bankruptcy case under Chapter 11 of the Bankruptcy Code in the United States Bankruptcy Court for the District of Delaware for the sale of the Company’s assets. In connection with the sale process the Company agreed to comply with certain process milestones which require, among other things, the entry into a purchase and sale agreement with a so-called “stalking horse bidder” by September 30, 2024, filing a bankruptcy case by October 1, 2024, and closing the sale by November 15, 2024. These expenses were partially offset by $1.1 million of gains recorded on the revaluation of liability classified stock warrants as well as the Series J and H warrants, and $0.1 million of gains recorded upon the sale of property, plant, and equipment during the three months ended September 30, 2024.

Income Tax Provision. We use a discrete year-to-date method in calculating quarterly provision for income taxes. Our provision for income taxes for the three months ended September 30, 2024 was consistent with the same period in 2023. For additional information regarding income taxes, see Part I, Item I, Note 13 – Income Taxes.

Net Loss. For the reasons stated above, our net loss totaled approximately $1.4 million for the three months ended September 30, 2024 compared to a net loss of $4.6 million for the three months ended September 30, 2023.

Net revenue decreased by $3.1 million, or 9%, during the nine months ended September 30, 2024, as compared to the same period in 2023 primarily due to a decrease in laser systems sales from the impact of the current macro-economic environment causing extended sales cycles, which includes elevated interest rates, partially offset by an increase in consumables and other revenue from improved utilization of installed laser systems. Net revenue was $32.5 million during the nine months ended September 30, 2024 compared to $35.7 million for the same period in 2023.

Cost of Revenue and Gross Profit: The following table summarizes our unaudited cost of revenue and gross profit for the nine months ended September 30, 2024 and 2023, as well as the amount of change and percentage of change (dollars in thousands):

Gross profit	$	12,327	37.9	%	$	13,200	37.0	%	$	(873	)		(6.6	)%

Gross profit as a percentage of net revenue typically fluctuates with product and regional mix, selling prices, product costs and revenue levels. Gross profit for the nine months ended September 30, 2024, was $12.3 million, or 38% of net revenue, which was slightly lower than a gross profit of $13.2 million, or 37% of net revenue, for the same period in 2023. Lower overall sales volume during the nine months ended September 30, 2024 contributed to the decrease in gross profit. The $1% increase in gross profit as a percentage of revenue when compared to the same period in 2023 reflects the improvement in supply chain issues that resulted in a decrease to warranty reserves, service expense and freight charges, partially offset by higher depreciation expense from facilities and manufacturing equipment placed into service during the three months ended September 30, 2023.

This decrease is primarily due to $2.2 million in lower compensation expense from the impact of our cost savings initiatives implemented over the last year and from lower commissions and bonus incentives, a $0.7 million decrease in depreciation expense recognized for equipment used in sales and marketing for demos, training and educational purposes, which was non-recurring in the nine months ended September 30, 2023, a $0.7 million decrease in travel and tradeshow related costs, a $0.2 million decrease in advertising costs, $0.1 million in severance expenses that did not occur in the nine months ended September 30, 2024, and $0.4 million less in various other expenses when compared to the same period in 2023.

General and Administrative Expense. General and administrative expenses of $7.5 million during the nine months ended September 30, 2024 was consistent when compared to the same period in 2023. Compensation and bonus incentives decreased by $0.5 million from the impact of cost savings initiatives implemented during the latter part of the second quarter of 2023, which was offset by a $0.2 million increase in our allowance for doubtful accounts reserve, and $0.3 million in higher legal, audit and consulting expenses.

Engineering and Development Expense. Engineering and development expenses during the nine months ended September 30, 2024 decreased by $1.1 million, or 25%, compared to the same period in 2023. This decrease is primarily due to $0.5 million in lower compensation expense from the impact of our cost savings initiatives implemented over the last year, and fewer engineering projects for 2024, as compared to the same period in 2023, resulting in a $0.2 million decrease in legal and consulting expenses, and a $0.4 million decrease in other miscellaneous costs.

Non-Operating Income (Loss)

Loss on Foreign Currency Transactions. We realized an approximately $0.3 million loss on foreign currency transactions during the nine months ended September 30, 2024 compared to an approximately $0.5 million loss on foreign currency transactions during the nine months ended September 30, 2024, primarily due to exchange rate fluctuations between the U.S. dollar and Euro, as well as other foreign currencies.

Interest Expense, Net. Interest expense was $1.8 million during the nine months ended September 30, 2024 which was consistent with the nine months ended September 30, 2023.

Other Income (Expense), Net. Other Expense for the nine months ended September 30, 2024 was $128 thousand and relates to $1.2 million in legal and financial advisory services incurred as a result of receiving a Default Notice from our term loan lender, SWK Funding LLC, and entering into a Forbearance Agreement. Under the Forbearance Agreement, the Company agreed to, among other things, prepare for and file a bankruptcy case under Chapter 11 of the Bankruptcy Code in the United States Bankruptcy Court for the District of Delaware for the sale of the Company’s assets. In connection with the sale process the Company agreed to comply with certain process milestones which require, among other things, the entry into a purchase and sale agreement with a so-called “stalking horse bidder” by September 30, 2024, filing a bankruptcy case by October 1, 2024, and closing the sale by November 15, 2024. In addition, there was $0.8 million of issuance costs from the February 2024 public offering that were allocated to the Class A Common Warrants, Class B Common Warrants, and Investor warrants and immediately expensed due to the liability classification of the warrants. These expenses were partially offset by $1.6 million of gains recorded on the revaluation of liability classified stock warrants, as well as the Series J and H warrants, and $0.3 million of gains recorded upon the sale of property, plant, and equipment during the nine months ended September 30, 2024.

Income Tax Provision. We use a discrete year-to-date method in calculating quarterly provision for income taxes. Our provision for income taxes for the nine months ended September 30, 2024 was consistent with the same period in 2023. For additional information regarding income taxes, see Part I, Item I, Note 13 – Income Taxes.

Net Loss. For the reasons stated above, our net loss totaled approximately $10.7 million for the nine months ended September 30, 2024 compared to a net loss of $15.3 million for the nine months ended September 30, 2023.

Liquidity and Capital Resources - Going Concern

As of September 30, 2024, we had approximately $3.4 million in cash and cash equivalents compared to $6.6 million as of December 31, 2023. Management defines cash and cash equivalents as highly liquid deposits with original maturities of 90 days or less when purchased. The decrease in cash and cash equivalents from December 31, 2023 was primarily due to cash used in operating activities of $11.1 million and principal payments on our term loan of $0.9 million, partially offset by net proceeds of $5.8 million from the February 2024 public offering, a $2.5 million bridge loan from SWK as part of the Forbearance Agreement, $0.4 million in proceeds from the disposal of property, plant, and equipment, and proceeds of $0.3 million from the exercise of preferred share warrants.

The following table summarizes our change in cash, cash equivalents and restricted cash (in thousands):


	Nine Months Ended
	September 30,
	2024			2023
Net cash flows used in operating activities	$	(11,144	)	$	(11,808	)
Net cash flows provided by (used in) investing activities		291			(1,126	)

Effect of exchange rate changes		22			13
Net change in cash and cash equivalents	$	(3,122	)	$	3,628

Operating Activities

Net cash used in operating activities consists of our net loss, adjusted for our non-cash charges, plus or minus working capital changes. Cash used in operating activities for the nine months ended September 30, 2024 totaled $11.1 million and was primarily comprised of our net loss of $10.7 million.

Investing Activities

Cash provided by investing activities for the nine months ended September 30, 2024 totaled $0.3 million and was comprised of the proceeds from the disposal of property, plant, and equipment.

Financing Activities

Net cash provided by financing activities for the nine months ended September 30, 2024 totaled $7.7 million and was derived from $5.8 million in net proceeds from the February 2024 public offering, a $2.5 million bridge loan from SWK as part of the

Forbearance Agreement, and $0.3 million from the exercise of preferred share warrants, partially offset by $0.9 million principal payments on our term loan.

Effect of Exchange Rate

The $22 thousand effect of exchange rate on cash for the nine months ended September 30, 2024 was due to recognized loss on foreign currency transactions, primarily driven by changes in the Euro during the period.

Future Liquidity Needs

As of September 30, 2024, we had a working capital deficit of approximately $11.4 million. Our principal sources of liquidity as of September 30, 2024 consisted of approximately $3.4 million in cash and cash equivalents and $3.5 million of net accounts receivable.

The Company will need to raise additional capital in the future. Additional capital requirements may depend on many factors, including, among other things, the rate at which the Company’s business grows, demands for working capital, manufacturing capacity, and any acquisitions that the Company may pursue. The Company expects that it will be required to raise capital through either equity or debt offerings. The Company cannot provide assurance that it will be able to successfully enter into any such equity or debt financings in the future or that the required capital will be available on acceptable terms, if at all, or that any such financing activity will not be dilutive to its stockholders especially in light of the fact that our common stock is no longer traded on the Nasdaq, which makes it harder to attract investors and limits the types of financings that can be conducted.

The Company has historically experienced losses from operations and has used cash and cash equivalents in operating activities. To be able to discharge our liabilities and commitments in the normal course of business, we must increase sales of our products, control or potentially reduce expenses, and establish profitable operations in order to generate cash from operations or obtain additional funds when needed.

The Company’s recurring losses, level of cash used in operations, and potential need for additional capital, along with uncertainties surrounding the Company’s ability to raise additional capital, and the filing of the Bankruptcy Petitions raise substantial doubt about the Company’s ability to continue as a going concern. The financial statements do not include any adjustments that might be necessary if the Company is unable to continue as a going concern.

Despite the February 2024 public offering, as well as the $2.5 million bridge loan from SWK as part of the DIP Financing, in order for the Company to continue operations beyond the next 12 months and be able to discharge its liabilities and commitments in the normal course of business, it must either raise additional capital or increase sales of our products, control or potentially reduce expenses, and establish profitable operations in order to generate cash from operations or obtain additional funds when needed.

We will endeavor to improve our financial condition and ultimately improve our financial results by increasing revenues through expansion of our product offerings, continuing to expand and develop our field sales force and distributor relationships both domestically and internationally, forming strategic arrangements within the dental and medical industries, educating dental and medical patients as to the benefits of our advanced medical technologies, and reducing expenses; however, there is no assurance that will be able to improve our financial condition.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Not applicable.

ITEM 4. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

Our management has evaluated, with the participation of our President and Chief Executive Officer and our Chief Financial Officer, the effectiveness of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act as of the end of the period covered by this Quarterly Report on Form 10-Q. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Based on that evaluation, our President and Chief Executive Officer and Chief Financial Officer have concluded that the Company’s disclosure controls and procedures were effective as of the end of the period covered by this report.

As discussed in our Annual Report on Form 10-K, we identified a material weakness in our internal control over financial reporting as we have determined that our controls were not operating effectively to assess the proper presentation of net loss per share attributable to common stockholders for the three and six months ended June 30, 2023 and the three and nine months ended September 30, 2023. This material weakness was the result of insufficient accounting assessment for unique and complex transactions outside of the business's normal operations.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.

In light of this material weakness, we performed additional analysis as deemed necessary to ensure that our financial statements were prepared in accordance with U.S. generally accepted accounting principles for the period ended December 31, 2023 and management believes that the financial statements included in the Annual Report on Form 10-K present fairly in all material respects our financial position, results of operations and cash flows for the periods presented.

Changes in Internal Controls over Financial Reporting

There was no change in our internal control over financial reporting that occurred during the period covered by this report that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting, except for the remediation of the material weakness identified in prior period as discussed blow.

To remediate the aforementioned material weakness, management has implemented additional controls to ensure that financial statement presentation, specifically in relation to net loss per share attributable to common stockholders, for unique and complex transactions are sufficiently investigated and documented at the time of inception, and technical experts are engaged for advisement.

PART II. OTHER INFORMATION

Unless specifically noted or the context clearly requires otherwise, all information set forth in this Quarterly Report on Form 10-Q relates to the Company as it existed as of September 30, 2024 and prior to the Company’s bankruptcy proceedings and does not, and is not intended and should not be read to, reflect the business, financial condition, and results of operations of any other entity, including any entity which may result from the bankruptcy proceedings.

ITEM 1. LEGAL PROCEEDINGS

From time to time, we are involved in legal proceedings and regulatory proceedings arising out of our operations. We establish reserves for specific liabilities in connection with legal actions that we deem to be probable and estimable. The ability to predict the ultimate outcome of such matters involves judgments, estimates, and inherent uncertainties. The actual outcome of such matters could differ materially from management’s estimates.

On January 4, 2023, Plaintiff PIPStek, LLC (a wholly-owned subsidiary of Sonendo, Inc.) filed a lawsuit against BIOLASE, Inc. in the Federal District Court for the District of Delaware, alleging that BIOLASE’s Waterlase dental laser product infringes two PIPStek patents. A third patent was subsequently added to the case. The Complaint seeks unspecified damages and injunctive relief, as well as costs and attorneys’ fees against BIOLASE. BIOLASE has answered denying all of PIPStek’s allegations and also asserting that the asserted patents are invalid and not infringed. BIOLASE intends to continue to vigorously and fully defend itself against PIPStek’s claims. The parties have exchanged preliminary contentions. Trial in this matter is currently set for May 12, 2025.

ITEM 1A. RISK FACTORS

Except as set forth below, there have been no material changes to our risk factors from those disclosed under “Risk Factors” in Part I, Item 1A of the 2023 Form 10-K. The risks and uncertainties described in the 2023 Form 10-K and set forth below are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also materially adversely affect our business, financial condition, or results of operations.

Due to our accumulated deficit, recurring and negative cash flow from operations for the year ended December 31, 2023 and the three and nine months ended September 30, 2024 there is substantial doubt about our ability to continue as a going concern.

Our audited consolidated financial statements for the year ended December 31, 2023 were prepared on a going concern basis in accordance with generally accepted accounting principles in the United States. The going concern basis assumes that we will continue in operation for the next 12 months and will be able to realize our assets and discharge our liabilities and commitments in the normal course of business. Thus, our consolidated financial statements do not include any adjustments that might be necessary if we are unable to continue as a going concern. Our recurring losses, negative cash flow, need for additional capital, and the uncertainties surrounding our ability to raise such capital raise substantial doubt about our ability to continue as a going concern. For us to continue operations beyond the next 12 months and be able to discharge our liabilities and commitments in the normal course of business, we must sell our products directly to end-users and through distributors, establish profitable operations through increased sales, decrease expenses, generate cash from operations or raise additional funds when needed. Our goal is to improve our financial condition and ultimately improve our financial results by increasing revenues through expanding awareness of the benefits of our dental lasers among dental specialists and general practitioners and reducing expenses. However, if we are unable to do so on a timely basis, we will be required to seek additional capital. In that event, we would seek additional funds through various financing sources, including the sale of our equity and debt securities, however, there can be no guarantees that such funds will be available on commercially reasonable terms, if at all especially in light of the fact that our common stock is no longer traded on the Nasdaq, which makes it harder to attract investors and limits the types of financings that can be conducted. If we are unable to raise additional capital, increase sales or reduce expenses, we will be unable to continue to fund our operations, develop our products, realize value from our assets, and discharge our liabilities in the normal course of business. If we become unable to continue as a going concern, we could have to liquidate our assets, and potentially realize significantly less than the values at which they are carried on our financial statements, and stockholders could lose all or part of their investment in our common stock. The Report of Independent Registered Public Accounting Firm from Macias Gini & O’Connell LLP contains an explanatory paragraph regarding our ability to continue as a going concern. In addition, the notes to our financial statements included in this Quarterly Report on Form 10-Q states that our recurring losses, level of cash used in operations, and potential need for additional capital, along with uncertainties surrounding our ability to raise additional capital, raise substantial doubt about our ability to continue as a going concern.

We are subject to risks and uncertainties associated with the bankruptcy proceedings.

The bankruptcy proceedings could have a material adverse effect on the Company’s business, financial condition, results of operations and cash flows. So long as the bankruptcy proceedings continue, our senior management may be required to spend a significant amount of time and effort dealing with bankruptcy proceedings instead of focusing on our business operations. The

bankruptcy proceedings also may make it more difficult to retain management and the key personnel necessary to the success and growth of our business. In addition, during the period of time we are involved in the bankruptcy proceedings, our customers and suppliers may lose confidence in our ability to restructure our business and may seek to establish alternative commercial relationships.

Other significant risks associated with the bankruptcy proceedings that could have a material adverse effect on our business, financial condition, results of operations and cash flows include or relate to the following, among others:

•

our ability to obtain approval from the Bankruptcy Court with respect to motions or other requests made to the Bankruptcy Court in the Bankruptcy Petitions;

•

our ability to obtain approval from the Bankruptcy Court with respect to the results of the Auction;

•

our ability to confirm and consummate the plan of reorganization;

•

our ability to consummate the sale of the Transferred Assets;

•

the effects of the filing of the Bankruptcy Petitions on our business and the interests of various constituents, including our stockholders;

•

the high costs of the bankruptcy proceedings and related fees;

•

our ability to maintain relationships with payors, suppliers, employees, and other third parties as a result of the Bankruptcy Petitions;

•

Bankruptcy Court rulings in the Bankruptcy Petitions as well as the outcome of other pending litigation and the outcome of the Bankruptcy Petitions in general;

•

the length of time that we will operate with chapter 11 protection;

•

the sufficiency of the Company’s cash on hand and ability to obtain sufficient financing to allow us to conduct our business during the pendency of the bankruptcy proceedings, confirm a plan of reorganization, or sell some or all of our assets during the bankruptcy proceedings in orderly fashion;

•

third-party motions in the Bankruptcy Petitions, which may interfere with our ability to confirm and consummate the plan of reorganization or another restructuring transaction, including motions by third parties that may force us into chapter 7 proceedings under the Bankruptcy Code, rather than chapter 11 proceedings; and

•

our ability to continue as a going concern.

Because of the risks and uncertainties associated with the bankruptcy proceedings, we may not be able to accurately predict or quantify the ultimate impact the bankruptcy proceedings may have on our business, financial condition, results of operations and cash flows, nor can we accurately predict the ultimate impact the bankruptcy proceedings may have on our corporate or capital structure.

We have experienced net losses for each of the quarter ended September 30, 2024 and the past three years, and we could experience additional losses and have difficulty achieving profitability in the future.

We had an accumulated deficit of $327.5 million as of September 30, 2024 and an accumulated deficit of $316.8 million as of December 31, 2023. We recorded net losses of $20.6 million and $28.6 million for the years ended December 31, 2023 and 2022, respectively, and net losses of $10.7 million and $15.3 million for the nine months ended September 30, 2024 and 2023, respectively. In order to achieve profitability, we must increase net revenue through new sales and control our costs. Failure to increase our net revenue and decrease our costs could cause our stock price to decline and could have a material adverse effect on our business, financial condition, and results of operations.

The National Securities Markets Improvement Act of 1996, which is a federal statute, prevents or preempts the states from regulating the sale of certain securities, which are referred to as “covered securities.” Because our Common Stock is not listed on the Nasdaq Capital Market, our Common Stock is not a covered security and therefore we are subject to regulation in each state in which we offer our securities. Accordingly, the types of financings that we may engage in are limited.

Because of the trading volatility often associated with low-priced stocks not listed on a national securities exchange, many brokerage houses and institutional investors have internal policies and practices that either prohibit them from investing in low-priced stocks or tend to discourage individual brokers from recommending low-priced stocks to their customers. Some of those policies and practices may make the processing of trades in low-priced stocks economically unattractive to brokers. Additionally, because brokers’ commissions on low-priced stocks generally represent a higher percentage of the stock price than commissions on higher-priced stocks, a low average price per share of common stock can result in individual stockholders paying transaction costs representing a higher percentage of their total share value than would be the case if the share price were higher.

As a result of Nasdaq delisting our securities from trading on its exchange, we could face significant material adverse consequences, including:

•

a limited availability of market quotations for our securities:

•

reduced liquidity with respect to our securities;

•

a determination that our common stock is a "penny stock" which will require brokers trading in our common stock to adhere to more stringent rules, possibly resulting in a reduced level of trading activity in the secondary trading market for our common stock;

•

a limited amount of news and analyst coverage for our company; and

•

a decreased ability to issue additional securities or obtain additional financing in the future.

Our common stock is subject to the “penny stock” rules of the SEC and the trading market in the securities is limited, which makes transactions in the stock cumbersome and may reduce the value of an investment in the stock.

Rule 15g-9 under the Exchange Act, establishes the definition of a “penny stock,” for the purposes relevant to us, as any equity security that has a market price of less than $5.00 per share or with an exercise price of less than $5.00 per share, subject to certain exceptions. For any transaction involving a penny stock, unless exempt, the rules require: (a) that a broker or dealer approve a person’s account for transactions in penny stocks; and (b) the broker or dealer receive from the investor a written agreement to the transaction, setting forth the identity and quantity of the penny stock to be purchased.

In order to approve a person’s account for transactions in penny stocks, the broker or dealer must: (a) obtain financial information and investment experience objectives of the person and (b) make a reasonable determination that the transactions in penny stocks are suitable for that person and the person has sufficient knowledge and experience in financial matters to be capable of evaluating the risks of transactions in penny stocks.

The broker or dealer must also deliver, prior to any transaction in a penny stock, a disclosure schedule prescribed by the SEC relating to the penny stock market, which, in highlight form: (a) sets forth the basis on which the broker or dealer made the suitability determination; and (b) confirms that the broker or dealer received a signed, written agreement from the investor prior to the transaction. Generally, brokers may be less willing to execute transactions in securities subject to the “penny stock” rules. This may make it more difficult for investors to dispose of our common stock and cause a decline in the market value of our common stock.

Disclosure also has to be made about the risks of investing in penny stocks in both public offerings and in secondary trading and about the commissions payable to both the broker or dealer and the registered representative, current quotations for the securities and the rights and remedies available to an investor in cases of fraud in penny stock transactions. Finally, monthly statements have to be sent disclosing recent price information for the penny stock held in the account and information on the limited market in penny stocks.
