NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

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 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, 2022 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 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 consolidated results of operations for the three and six months ended June 30, 2023 are not necessarily indicative of the results for the full year. The accompanying unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the fiscal year ended December 31, 2022, included in BIOLASE’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022 filed with the Securities and Exchange Commission (the “SEC”) on March 28, 2023 (the “2022 Form 10-K”).

Reverse Stock Split

At a special meeting of BIOLASE stockholders held on July 20, 2023 (the "special 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, at a ratio between one-for-two (1:2) and one-for-one hundred (1:100). Immediately after the special meeting, BIOLASE's board of directors (the "Board") approved a one-for-one hundred (1:100) reverse stock split of the outstanding shares of BIOLASE common stock (the “2023 Reverse Stock Split”). On July 26, 2023, BIOLASE filed an amendment to the Certificate of Incorporation with the Secretary of State of the State of Delaware to effect the 2023 Reverse Stock Split, which became effective on July 27, 2023. The amendment did not change the number of authorized shares of BIOLASE common stock.

Except as the context otherwise requires, all common stock share numbers, share price amounts (including exercise prices, conversion prices, and closing market prices), shares issued upon the conversion of preferred shares, and shares issued upon the exercise of warrants contained in the unaudited consolidated financial statements and notes thereto have been retroactively adjusted to reflect the 2023 Reverse Stock Split.

Liquidity and Management’s Plans

The Company incurred losses from operations and used cash in operating activities for the three and six months ended June 30, 2023 and for the years ended December 31, 2022, 2021, and 2020. 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, 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.

As of June 30, 2023, the Company had working capital of approximately $9.8 million. The Company’s principal sources of liquidity as of June 30, 2023 consisted of approximately $6.9 million in cash and cash equivalents and $5.7 million of net accounts receivable. As of December 31, 2022, the Company had working capital of approximately $11.2 million, $4.2 million in cash and cash equivalents and $5.8 million of net accounts receivable. The increase in cash and cash equivalents since December 31, 2022 was primarily due to $8.5 million net proceeds from the January 2023 public offering, $3.7 million net proceeds from the May 2023 public

offering, and $0.6 million proceeds from the exercise of warrants. This increase was partially offset by a net loss of $10.7 million and $0.9 million in capital expenditures. For additional information on the January 2023 public offering and the May 2023 public offering, see Note 4 – Convertible Redeemable Preferred Stock and Stockholders’ Equity—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, 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 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 consolidated financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect amounts reported in the consolidated financial statements and the accompanying notes. Significant estimates in these 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, and the provision or benefit for income taxes. 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 2022 audited financial statements included in the 2022 Form 10-K. Management believes that there have been no significant changes during the six months ended June 30, 2023 in the Company’s critical accounting policies from those disclosed in the Company’s 2022 audited financial statements included in the 2022 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 six months ended June 30, 2023 and 2022, 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 June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The standard’s main goal is to improve financial reporting by requiring earlier recognition of credit losses on financing receivables and other financial assets in scope and to replace the incurred loss impairment methodology under current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The Company will be required to use a forward-looking expected credit loss model for accounts receivables, loans, and other financial instruments. Credit losses relating to available-for-sale debt securities will also be recorded through an allowance for credit losses rather than as a reduction in the amortized cost basis of the securities. The Company adopted this guidance effective January 1, 2023, and the adoption of this standard did not have a significant impact on its 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 90% of net revenue for the three and six months ended June 30, 2023, and 90% of net revenue for the three and six months ended June 30, 2022. 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 10% of net revenue for the three and six months ended June 30, 2023, and 10% of net revenue for the three and six months ended June 30, 2022. 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 $0.4 million as of June 30, 2023 and December 31, 2022.

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 as the customer attends a training program or upon the expiration of the obligation, which is generally after nine 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):


	June 30,			December 31,
	2023			2022
Undelivered elements (training, installation, product and support services)	$	431		$	447
Extended warranty contracts		2,116			2,082
Total deferred revenue		2,547			2,529
Less: long-term portion of deferred revenue		(311	)		(418	)
Deferred revenue — current	$	2,236		$	2,111

The balance of contract assets was immaterial as the Company did not have a significant amount of uninvoiced receivables at June 30, 2023 and December 31, 2022.

The amount of revenue recognized during the six months ended June 30, 2023 and 2022 that was included in the opening contract liability balance related to undelivered elements was $0.3 million and $0.4 million, respectively. The amount of revenue recognized related to extended warranty contracts was $1.1 million and $1.0 million, for the six months ended June 30, 2023 and 2022, 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):

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

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 June 30, 2023, 370,000 shares were designated as Series H, par value $0.001 per share and 125,000 shares were designated as Series I, par value $0.001 per share.

Preferred Stock

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 an additional 80,769 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 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 BIOLASE 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 "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 as they are contingently redeemable prior to the Maturity Date and the conversion from preferred shares to shares of BIOLASE common stock is at the option of the holder at any time before the Maturity Date. The Series H warrants was classified as a liability as the warrants are convertible into preferred shares, which are mandatorily redeemable in cash upon the Maturity Date if they are not converted to shares of BIOLASE 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 Shares 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 shares, the value of the Series H Convertible Preferred shares 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.

During the three months ended June 30, 2023, 20,000 of the Series H warrants were converted to Series H Convertible Preferred shares and during the three months ended June 30, 2023, 183,000 Series H Convertible Preferred shares were converted to BIOLASE common stock.

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 BIOLASE 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"). On July 20, 2023, the Series I Initial Redemption occurred, and on July 27, 2023, the Series I Subsequent Redemption occurred. As a result, no shares of Series I Preferred Stock remain outstanding as of July 27, 2023.

Series G Preferred Stock

On March 1, 2022, the Board declared a dividend of one one-thousandth of a share of Series G Preferred Stock, par value $0.001 per share ("Series G Preferred Stock"), for each share of BIOLASE common stock outstanding as of close of market on March 25, 2022 (as calculated on a pre 2022 Reverse Stock Split basis). The certificate of designation for the Series G Preferred Stock provided that all shares of Series G Preferred Stock not present in person or by proxy at the 2022 Annual Meeting immediately prior to the opening of the polls at the 2022 Annual Meeting would be automatically redeemed (the “Series G Initial Redemption”) and that any outstanding shares of Series G Preferred Stock that have not been redeemed pursuant to the Series G 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 2022 Reverse Stock Split that was subject to the vote at the 2022 Annual Meeting (the “Series G Subsequent Redemption”). On April 28, 2022, both the Series G Initial Redemption and the Series G Subsequent Redemption occurred. As a result, no shares of Series G Preferred Stock remain outstanding. On June 6, 2022, the Series G Preferred Stock was eliminated.

Series F Convertible Preferred Stock

On July 23, 2020, the Company consummated the sale of an aggregate of 18,000 shares of Series F Preferred Stock, par value $0.001 per share ("Series F Preferred Stock"), and 45,000,000 warrants (the “July 2020 Warrants”), exercisable for 18,000 shares of BIOLASE common stock, through a registered rights offering the Company completed on July 22, 2020 (the “Rights Offering”). Each share of Series F Preferred Stock was convertible at the Company’s option at any time on or after July 22, 2021 or at the option of the holder at any time, into the number of shares of BIOLASE common stock determined by dividing the $1,000 stated value per share of the Series F Preferred Stock by a conversion price of $1,000 per share. Each share of Series F Preferred Stock was convertible into one share of common stock, and 2,500 July 2020 Warrants entitled the holder thereof to purchase one share BIOLASE common stock at an exercise price of $1,000 per share.

In accordance with applicable accounting standards, the $18.0 million gross proceeds from the Rights Offering were allocated to the Series F Preferred Stock and the July 2020 Warrants in the amount of $2.7 million and $15.3 million, respectively. The allocation was based on the fair value of the July 2020 Warrants of $15.3 million as of the commitment date, with the residual proceeds of $2.7 million allocated to the Series F Preferred Stock.

The Series F Preferred Stock contained a beneficial conversion feature which resulted in a deemed dividend to preferred stockholders of approximately $2.7 million, upon immediate accretion. Additionally, the July 2020 Warrants were recognized as a discount to the Series F Preferred Stock. Upon conversion, including the conversion described below, this discount was accreted and also recognized as a deemed dividend to preferred stockholders in the amount of $0.2 million, $0.5 million and $14.7 million for the years ended December 31, 2022, 2021, and 2020, respectively.

The remaining shares of Series F Preferred Stock were converted into shares of BIOLASE common stock in the first quarter of 2022 with none outstanding as of June 30, 2023 and December 31, 2022. On March 3, 2022, the Series F Preferred Stock was eliminated.

The purposes of the 2018 Plan are (i) to align the interests of the Company’s stockholders and recipients of awards under the 2018 Plan by increasing the proprietary interest of such recipients in the Company’s growth and success; (ii) to advance the interests of the Company by attracting and retaining non-employee directors, officers, other employees, consultants, independent contractors, and agents; and (iii) to motivate such persons to act in the long-term best interests of the Company and its stockholders.

Phantom Awards and Stock Appreciation Rights

Since March 31, 2021, the Company has issued 4,414 phantom RSUs in lieu of stock-settled RSUs historically granted for leadership bonuses and non-employee director service. The phantom RSUs have either time-based or performance-based vesting conditions and could be settled in cash in 2024 with the Company's option to settle the award in BIOLASE 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 current limitation on the number of remaining shares authorized for issuance. In 2022, as a result of the 2022 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. The expense recognized during the three and six months ended June 30, 2023 was $0.1 million and $0.2 million, respectively, and the expense recognized during the three and six months ended June 30, 2022 was ($0.1 million) and $0.0 million, respectively, due to decreases in fair value. As of June 30, 2023, $0.4 million was included in accrued liabilities on the consolidated balance sheet. The balance included in long-term liabilities as of December 31, 2022, was $0.3 million.

During the year ended December 31, 2021, the Company issued approximately 386 SARs 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 BIOLASE common stock at the sole discretion of the Board. These SARS were included in accrued liabilities on the consolidated balance sheet and not considered stock-based compensation due to the cash-settlement feature of the award and limitation on the number of remaining shares authorized for issuance. In 2022, as a result of the 2022 Reverse Stock Split, the SARs were reclassed to equity and included as a component of additional paid-in-capital on the consolidated balance sheet in the amount of $0.5 million. These SARs were fully vested in 2022. No expense was recognized during the three and six months ended June 30, 2023 and the expense recognized during the three and six months ended June 30, 2022 was $0.1 million and $0.3 million, respectively, and was included in additional paid-in-capital on the consolidated balance sheet as of December 31, 2022.

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 income (loss) is adjusted for any deemed dividends to preferred stockholders to compute net income attributable to common stockholders. The January 2023 Pre-Funded Warrants were included in the calculation of basic and diluted loss per share for the three and six months ended June 30, 2023 as the underlying warrant shares are issuable for little or no cash consideration.

Outstanding stock options, RSUs, preferred shares, and warrants to purchase approximately 366,154 and 25,919 shares were not included in the calculation of diluted loss per share amounts for the periods ended June 30, 2023 and June 30, 2022, respectively, as their effect would have been anti-dilutive.

NOTE 5—INVENTORY

Inventory is valued at the lower of cost or net realizable value and is comprised of the following (in thousands):


	June 30,		December 31,
	2023		2022
Raw materials	$	6,873	$	6,697
Work-in-process		1,841		1,871
Finished goods		4,616		7,316
Inventory	$	13,330	$	15,884

Inventory has been reduced by estimates for excess and obsolete amounts totaling $2.1 million and $2.2 million as of June 30, 2023 and December 31, 2022, respectively.

During the three months ended June 30, 2023, $1.7 million of inventory was reclassed to property, plant and equipment for lasers transferred to potential customers and other sales representatives without any payment in prior periods.

NOTE 6—PROPERTY, PLANT, AND EQUIPMENT

Property, plant, and equipment, net is comprised of the following (in thousands):


	June 30,			December 31,

Property, plant, and equipment, net before land		6,213			4,123
Land		158			155
Property, plant, and equipment, net	$	6,371		$	4,278

Depreciation and amortization expense related to property, plant, and equipment totaled $1.4 million and $1.6 million for the three and six months ended June 30, 2023, respectively, and $0.1 million and $0.3 million for the three and six months ended June 30, 2022, respectively.

During the three months ended June 30, 2023, the Company revised its accounting for laser equipment transferred as part of its marketing efforts to potential customers and other sales representatives without any payment. As a result, a cumulative adjustment of $0.8 million was recorded to depreciation expense in the three and six months ended June 30, 2023. If the December 31, 2022 balance sheet was conformed to current period presentation, in addition to recording the cumulative adjustment to retained earnings, the adjustment would have decreased inventory by $1.7 million and increased property, plant and equipment, net by $0.9 million.

NOTE 7—INTANGIBLE ASSETS AND GOODWILL

The Company conducted its annual impairment test of goodwill as of September 30, 2022 and determined that there was no impairment. 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, 2022, due to the sustained decrease in the stock price of BIOLASE 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 our 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 15.7% and various revenue growth rates utilized in the financial forecast of future cash flows.

Due to the further decrease in the stock price of BIOLASE common stock during the three months ended March 31, 2023 decreasing the implied fair value of the business, the Company performed an additional quantitative assessment of impairment over

goodwill and determined that there was no impairment to our goodwill as of March 31, 2023. 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 25.0% and various revenue growth rates utilized in the financial forecast of future cash flows. No events have occurred since March 31, 2023 through the date of these unaudited consolidated financial statements that would trigger further impairment testing of the Company’s intangible assets and goodwill.

As of June 30, 2023 and December 31, 2022, the Company had goodwill of $2.9 million. As of June 30, 2023 and December 31, 2022, all intangible assets have been fully amortized, and no amortization expense was recognized during the three and six months ended June 30, 2023 and 2022.

(1) Estimated using London Interbank Bank Offered Rate (“LIBOR”) as of June 30, 2023

Term Loan

On November 9, 2018, the Company entered into a five-year secured Credit Agreement (as amended, restated, and supplemented from time to time, the “Credit Agreement”) with SWK Funding LLC (“SWK”), pursuant to which the Company has outstanding principal of $13.3 million (“SWK Loan”) as of June 30, 2023. In addition, pursuant to the Credit Agreement, we are 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 2022 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. In connection with the Ninth Amendment, the Company prepaid $1.0 million of the outstanding loan balance. Principal repayments begin in November 2023 and will be $0.7 million quarterly 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.

As of June 30, 2023, the Company was in compliance with the debt covenants of the Credit 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.

NOTE 10—LEASES

The Company enters into operating leases primarily for real estate, office equipment, and fleet vehicles.

No individual customer represented more than 10% of the Company’s revenue for the three and six months ended June 30, 2023 or 2022.

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.

No individual customer represented more than 10% of the Company’s accounts receivable at June 30, 2023. As of December 31, 2022 accounts receivable from one customer totaled approximately 12% of total gross accounts receivable. The entire balance was either current or outstanding for less than 30 days.

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 six months ended June 30, 2023 and 2022. 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 six months ended June 30, 2023, the Company recorded an income tax provision of $31,000, resulting in an effective tax rate of 0.6% and 0.3%, respectively. During the three and six months ended June 30, 2022, the Company recorded an income tax provision of $23,000 and $40,000, respectively, resulting in an effective tax rate of 0.4%. The income tax provisions and

benefit for the three and six months ended June 30, 2023 and 2022 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

At a special meeting of BIOLASE stockholders held on July 20, 2023 (the "special 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, at a ratio between one-for-two (1:2) and one-for-one hundred (1:100). Immediately after the special meeting, the Board approved a one-for-one hundred (1:100) reverse stock split of the outstanding shares of BIOLASE common stock (the “2023 Reverse Stock Split”). On July 26, 2023, BIOLASE filed an amendment to the Certificate of Incorporation with the Secretary of State of the State of Delaware to effect the 2023 Reverse Stock Split, which became effective on July 27, 2023. The amendment did not change the number of authorized shares of BIOLASE common stock. On July 20, 2023, the Series I Initial Redemption occurred and on July 27, 2023 the Series I Subsequent Redemption occurred. As a result, no shares of Series I Preferred Stock remain outstanding.

On July 21, 2023, the Company filed a registration statement on Form S-1 for the issuance of units consisting of common stock and warrants to purchase common stock. The equity raise, which is subject to conditions including the SEC declaring the registration statement effective and market conditions, is expected to be completed in the third quarter of 2023.

On August 10, 2023, the Company entered into Change in Control Agreements with each of Jennifer Bright and Steven Sandor, the Company’s Chief Financial Officer and Chief Operating Officer, respectively. Pursuant to the Agreements, in the event of a change in control of the Company, as defined therein, in the event of Ms. Bright’s or Mr. Sandor’s termination without cause or resignation for good reason within 18 months following such change in control, Ms. Bright and Mr. Sandor will be entitled to certain severance benefits, including a lump sum payment equal to nine months of their base salary then in effect. The foregoing description of the Change in Control Agreements does not purport to be complete and is qualified in its entirety by reference to the full text of the Agreement, a copy of which is filed as Exhibit 10.1 and 10.2 to this Quarterly Report on Form 10-Q.

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, 2022 we maintained approximately 259 active and 24 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, 2022, we have sold over 45,500 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 June 30, 2023, the sale of lasers accounted for approximately 61% of our total sales, and consumables, accessories, and services accounted for approximately 39% of our total sales.

We currently operate in a single reportable business segment. We had net revenues of $14.3 million and $24.8 million for the three and six months ended June 30, 2023, respectively, and net revenues of $12.2 million and $22.4 million for the three months ended June 30, 2022, respectively. We had net losses of $4.9 million and $10.7 million for the three and six months ended June 30, 2023, respectively, and $5.6 million and $10.4 million for the three and six months ended June 30, 2022, respectively. We had total assets of $39.6 million and $38.2 million as of June 30, 2023 and December 31, 2022, respectively.

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 growth of 17% and 11% for the three and six months ended June 30, 2023, respectively, compared to the same periods in 2022. The Company is currently forecasting revenue for fiscal year 2023 to be significantly above

fiscal year 2022, as the Company's strategy described above continues to generate sales to new customers and additional consumable sales to existing customers.

In 2021, we designed, developed, received FDA clearance for, and began production of a laser using our proprietary Er,Cr:YSGG laser technology in partnership with EdgeEndo, a leading endodontic company. The EdgePro is a state-of-the-art microfluidic irrigation device designed to clean and disinfect root canals. The partnership with EdgeEndo is our first exclusive original equipment manufacturer ("OEM") agreement.

Recent Developments

Series H Preferred Stock

On May 24, 2023, BIOLASE entered into an underwriting agreement (the “Underwriting Agreement”), pursuant to which BIOLASE agreed to sell to the underwriters in a firm commitment underwritten public offering 175,000 units (each, a “Unit” and collectively, the “Units”), with each Unit consisting of (A) one share of the Company’s 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 (each, a “Warrant” and collectively, 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%. BIOLASE also registered under the Registration Statement an additional 80,769 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”) and the shares of Common Stock issuable upon conversion of the Series H Convertible Preferred Stock issued as PIK dividends. Each 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. Gross proceeds from the offering were $4.6 million before broker fees and related expenses.

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"), of BIOLASE 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"). On July 20, 2023 the Series I Initial Redemption occurred, and on July 27, 2023, the Series I Subsequent Redemption occurred. As a result, no shares of Series I Preferred Stock remain outstanding as of July 27, 2023.

Critical Accounting Policies

The unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) which require us to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and revenues and expenses reported during the period. Information with respect to our critical accounting policies that we believe could have the most significant effect on our reported results and require subjective or complex judgments by management is contained in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” of the 2022 Form 10-K. There have been no significant changes during the six months ended June 30, 2023 in our critical accounting policies from those disclosed in Item 7 of the 2022 Form 10-K.

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 and amortization, stock-based and other non-cash compensation, severance expense, and the change in allowance for doubtful accounts. 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. 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.

The following table contains a reconciliation of non-GAAP Adjusted EBITDA to GAAP net loss attributable to common stockholders (in thousands):

The following table summarizes our unaudited net revenue by geographic location based on the location of customers for the three months ended June 30, 2023 and 2022, as well as the amount of change and percentage of change in each geographic revenue category (dollars in thousands):


	Three Months Ended
	June 30,								Amount		Percent
	2023				2022				Change		Change
United States	$	10,741	75.2	%	$	8,899	72.7	%	$	1,842		20.7	%

Net revenue	$	14,286	100.0	%	$	12,235	100.0	%	$	2,051		16.8	%

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 during the three months ended June 30, 2023 increased by $2.1 million, or 17% as compared to the same period in 2022 primarily due to an increase in laser sales in the U.S. and consumable sales. Net revenue was $14.3 million during the three months ended June 30, 2023 compared to $12.2 million for the same period in 2022.

Cost of Revenue and Gross Profit: The following table summarizes our unaudited cost of revenue and gross profit for the three months ended June 30, 2023 and 2022, as well as the amount of change and percentage of change (dollars in thousands):


	Three Months Ended
	June 30,								Amount		Percent
	2023				2022				Change		Change
Net revenue	$	14,286	100.0	%	$	12,235	100.0	%	$	2,051		16.8	%
Cost of revenue		8,168	57.2	%		7,094	58.0	%		1,074		15.1	%
Gross profit	$	6,118	42.8	%	$	5,141	42.0	%	$	977		19.0	%

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 June 30, 2023, was $6.1 million, or 43% of net revenue, an increase of approximately $1.0 million, or 19%, as compared with gross profit of $5.1 million, or 42% of net revenue, for the same period in 2022. The increase of 1% in gross profit as a percentage of net revenue when compared to the same period in 2022 reflects improvement from changing to new suppliers, which resulted in lower warranty expenses.

Operating Expenses: The following table summarizes our unaudited operating expenses (including as a percentage of net revenue) for the three months ended June 30, 2023 and 2022, as well as the amount of change and percentage of change (dollars in thousands):


	Three Months Ended
	June 30,								Amount			Percent
	2023				2022				Change			Change
Sales and marketing	$	6,189	43.3	%	$	5,402	44.1	%	$	787			14.6	%
General and administrative		2,357	16.5	%		3,141	25.7	%		(784	)		(25.0	)%
Engineering and development		1,444	10.1	%		1,653	13.5	%		(209	)		(12.6	)%
Total operating expenses	$	9,990	69.9	%	$	10,196	83.3	%	$	(206	)		(2.0	)%

Sales and Marketing Expense. Sales and marketing expenses during the three months ended June 30, 2023 increased by $0.8 million, or 15%, as compared to the same period in 2022. This increase of $0.8 million is primarily due to $1.1 million in recognition of depreciation expense for equipment used in sales and marketing for demos, training and educational purposes, of which $0.8 million was non-recurring, and $0.1 million for severance expense that did not occur in 2022. These increases were partially offset by $0.2 million in decreased advertising spending, $0.1 million in lower travel and tradeshow-related expenses and $0.1 million in lower compensation expense.

General and Administrative Expense. General and administrative expenses during the three months ended June 30, 2023 decreased by $0.8 million, or 25%, compared to the same period in 2022. This decrease of $0.8 million is primarily due to a $0.5 million decrease in legal and consulting spending and a $0.4 million decrease in stock-based compensation expense, partially offset by $0.1 million of increases in various other expenses.

Engineering and Development Expense. Engineering and development expenses during the three months ended June 30, 2023 decreased by $0.2 million, or 13%, compared to the same period in 2022. This decrease of $0.2 million is primarily from compensation, legal and consulting expenses driven by fewer engineering projects for 2023 as compared to 2022.

Non-Operating Loss

Loss on Foreign Currency Transactions. We realized an approximately $0.2 million loss on foreign currency transactions during the three months ended June 30, 2023 compared to an approximately $0.1 million loss on foreign currency transactions during the three months ended June 30, 2022, 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 June 30, 2023 compared to $0.4 million for the same period in 2022, an increase of 36%. This increase was due to the rise in interest rates on our term loan.

Other (Income) Expense, Net. Other Expenses during the three months ended June 30, 2023 was $0.1 million and relates to issuance costs from the May 2023 public offering that were allocated to the Series H warrants and immediately expensed due to the liability classification of the awards. These expenses were partially offset by gains recorded on the revaluation of these awards during the period.

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 June 30, 2023 was consistent with the same period in 2022. 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 $4.9 million for the three months ended June 30, 2023 compared to a net loss of $5.6 million for the three months ended June 30, 2022.

Cost of revenue		15,299	61.8	%		12,531	55.9	%		2,768			22.1	%
Gross profit	$	9,454	38.2	%	$	9,870	44.1	%	$	(416	)		(4.2	)%

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 six months ended June 30, 2023, was $9.5 million, or 38% of net revenue, a decrease of approximately $0.4 million, or 4%, as compared with gross profit of $9.9 million, or 44% of net revenue, for the same period in 2022. The decrease of 6% in gross profit as a percentage of net revenue reflects (i) the impact of supply chain issues we have encountered

during the three months ended March 31, 2023 compared to the same period in 2022 requiring us to change to new suppliers, (ii) the effect of an increase in the percentage of our revenue generated outside the U.S., where margins are lower than our U.S. business, and (iii) a higher volume of lower margin OEM products launched at the beginning of 2022.

Operating Expenses: The following table summarizes our unaudited operating expenses (including as a percentage of net revenue) for the six months ended June 30, 2023 and 2022, as well as the amount of change and percentage of change (dollars in thousands):


	Six Months Ended
	June 30,								Amount			Percent
	2023				2022				Change			Change
Sales and marketing	$	10,812	43.6	%	$	10,216	45.6	%	$	596			5.8	%
General and administrative		4,815	19.5	%		5,717	25.5	%		(902	)		(15.8	)%
Engineering and development		2,991	12.1	%		3,197	14.3	%		(206	)		(6.4	)%
Total operating expenses	$	18,618	75.2	%	$	19,130	85.4	%	$	(512	)		(2.7	)%

Sales and Marketing Expense. Sales and marketing expenses during the six months ended June 30, 2023 increased by $0.6 million, or 6%, as compared to the same period in 2022. This increase of $0.6 million is primarily due to $1.1 million in recognition of depreciation expense for equipment used in sales and marketing for demos, training and educational purposes, of which $0.8 million was non-recurring, $0.1 million for severance expense that did not occur in 2022 and $0.1 million in higher travel and tradeshow-related expenses. These increases were partially offset by $0.4 million in lower compensation expense and $0.3 million in decreased advertising spending.

General and Administrative Expense. General and administrative expenses during the six months ended June 30, 2023 decreased by $0.9 million, or 16%, compared to the same period in 2022. This decrease of $0.9 million is primarily due to an $0.8 million decrease in legal and consulting spending, a $0.2 million decrease in stock-based compensation expense and $0.1 million in lower allowance for doubtful accounts, partially offset by $0.2 million of increases in various other expenses.

Engineering and Development Expense. Engineering and development expenses during the six months ended June 30, 2023 decreased by $0.2 million, or 6%, compared to the same period in 2022. This decrease is primarily from compensation, legal and consulting expenses driven by fewer engineering projects for 2023 as compared to 2022.

Non-Operating Loss

Loss on Foreign Currency Transactions. We realized an approximately $0.2 million loss on foreign currency transactions during the six months ended June 30, 2023 compared to an approximately $0.2 million loss on foreign currency transactions during the six months ended June 30, 2022, 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 $1.2 million during the six months ended June 30, 2023 compared to $0.9 million for the same period in 2022, an increase of 34%. This increase was due to the rise in interest rates on our term loan.

Other (Income) Expense, Net. Other Expenses during the six months ended June 30, 2023 was $0.1 million and relates to issuance costs from the May 2023 public offering that were allocated to the Series H warrants and immediately expensed due to the liability classification of the awards. These expenses were partially offset by gains recorded on the revaluation of these awards during the period.

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 six months ended June 30, 2023 was consistent with the same period in 2022. 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 six months ended June 30, 2023 compared to a net loss of $10.4 million for the six months ended June 30, 2022.

Liquidity and Capital Resources

At June 30, 2023, we had approximately $6.9 million in cash and cash equivalents compared to $4.2 million as of December 31, 2022. Management defines cash and cash equivalents as highly liquid deposits with original maturities of 90 days or less when purchased. The increase in cash and cash equivalents from December 31, 2022 was primarily due to $8.5 million net proceeds from

the January 2023 public offering, $3.7 million net proceeds from the May 2023 public offering, and $0.6 million proceeds from the exercise of warrants, partially offset by a net loss of $10.7 million and $0.9 million in capital expenditures during the six months ended June 30, 2023. The Company incurred losses from operations and used cash in operating activities for the three and six months ended June 30, 2023 and for the years ended December 31, 2022, 2021, and 2020. 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, 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.

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


	Six Months Ended
	June 30,
	2023			2022
Net cash flows used in operating activities	$	(9,220	)	$	(14,633	)
Net cash flows used in investing activities		(944	)		(578	)
Net cash flows provided by financing activities		12,793			4,849
Effect of exchange rate changes		120			(264	)
Net change in cash, cash equivalents and restricted cash	$	2,749		$	(10,626	)

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 six months ended June 30, 2023 totaled $9.2 million and was primarily comprised of our net loss of $10.7 million.

Investing Activities

Cash used in investing activities for the six months ended June 30, 2023 totaled $0.9 million and was comprised of the purchase of property, plant, and equipment. We expect cash flows used in investing activities to decrease in the remainder of 2023 due to the completion of our new training facility.

Financing Activities

Net cash provided by financing activities for the six months ended June 30, 2023 totaled $12.8 million and was derived from the $8.5 million net proceeds from the January 2023 public offering, $3.7 million net proceeds from the May 2023 public offering, and $0.6 million proceeds from the exercise of warrants.

Effect of Exchange Rate

The $0.1 million effect of exchange rate on cash for the six months ended June 30, 2023 was due to recognized loss on foreign currency transactions, primarily driven by changes in the Euro during the period.

Future Liquidity Needs

As of June 30, 2023, we had working capital of approximately $9.8 million. Our principal sources of liquidity as of June 30, 2023 consisted of approximately $6.9 million in cash and cash equivalents and $5.7 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. On July 21, 2023, the Company filed a registration statement on Form S-1 for the issuance of units consisting of common stock and warrants to purchase common stock. The equity raise, which is subject to conditions including the SEC declaring the registration statement effective and market conditions, is expected to be completed in the third quarter of 2023.

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, 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.

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 1A. RISK FACTORS

A description of the risk factors associated with our business is contained in “Risk Factors” in Part I, Item 1A of the 2022 Form 10-K. There have been no material changes to our Risk Factors as previously reported, except for the addition of the Risk Factors below.

Failure to meet NASDAQ’s continued listing requirements could result in the delisting of our common stock, negatively impact the price of our common stock and negatively impact our ability to raise additional capital.

On January 11, 2023, we received a deficiency letter from the Listing Qualifications Department (the “Staff”) of the Nasdaq Stock Market (“Nasdaq”) notifying us that, for the last 30 consecutive business days, ending on January 10, 2023, the bid price for our common stock had closed below the minimum $1.00 per share requirement for continued inclusion on the Nasdaq Capital Market pursuant to Nasdaq Listing Rule 5550(a)(2) (the “Bid Price Rule”). In accordance with Nasdaq rules, we were provided an initial period of 180 calendar days, or until July 10, 2023 (the “Compliance Date”), to regain compliance with the Bid Price Rule.

On June 8, 2023, we were notified by the Staff of Nasdaq that we did not meet the minimum closing bid price requirement of $1.00 for continued listing, as set forth in the Bid Price Rule, as the Staff has determined that as of June 8, 2023, the Company’s securities had a closing bid price of $0.10 or less for ten consecutive trading days, from May 24, 2023 through June 7, 2023. As such, the Staff has determined to delist the Company’s common stock from the Nasdaq Capital Market and to suspend trading of the common stock at the opening of business on June 20, 2023, and file a Form 25-NSE with the SEC. We timely requested a hearing to appeal this determination, which stayed the suspension of our common stock pending the panel’s decision.

We subsequently requested the Panel grant us a temporary exception to regain compliance with the Bid Price Rule. On July 5, 2023, the Panel granted us an exception until August 11, 2023 to demonstrate bid price compliance subject to us taking the following actions: (i) on July 20, 2023, we shall obtain stockholder approval for a reverse stock split at a ratio that is sufficient to regain and maintain long term compliance with the Bid Price Rule; (ii) on or before July 31, 2023, we shall effect a reverse stock split and, thereafter, maintain a $1.00 closing bid price for a minimum of ten consecutive business days; and (iii) on August 11, 2023, we shall have demonstrated compliance with the Bid Price Rule, by evidencing a closing bid price of $1.00 or more per share for a minimum of ten consecutive trading sessions.

On July 20, 2023, BIOLASE held a special meeting of BIOLASE stockholders where the stockholders approved an amendment to our Certificate of Incorporation to effect a reverse stock split of BIOLASE common stock, at a ratio between one-for-two (1:2) and one-for-one hundred (1:100). Immediately after the special meeting, our Board approved a one-for-one hundred (1:100) reverse stock split of the outstanding shares of BIOLASE common stock (the “2023 Reverse Stock Split”). On July 26, 2023, BIOLASE filed an amendment to the Certificate of Incorporation with the Secretary of State of the State of Delaware to effect the 2023 Reverse Stock Split, which became effective on July 27, 2023.

While we have taken definitive steps to comply with all applicable conditions and criteria for continued listing on Nasdaq, there can be no assurances, however, that we will be able to do so. We must satisfy the time frame granted by the Panel or Nasdaq will provide written notification that our securities will be delisted. If we cannot regain compliance with the Bid Price Rule, our common stock will be subject to delisting. If that were to occur, our common stock would be subject to rules that impose additional sales practice requirements on broker-dealers who sell our securities. The additional burdens imposed upon broker-dealers by these requirements could discourage broker-dealers from effecting transactions in our common stock. This would adversely affect the ability of investors to trade our common stock and would adversely affect the value of our common stock. These factors could contribute to lower prices and larger spreads in the bid and ask prices for our common stock.

Due to our accumulated deficit, recurring and negative cash flow from operations for the year ended December 31, 2022 and the quarter ended June 30, 2023, there is substantial doubt about our ability to continue as a going concern.

We incurred losses from operations and used cash in operating activities for the three and six months ended June 30, 2023 and for the years ended December 31, 2022, 2021, and 2020. Our 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, raise substantial doubt about

the Company’s ability to continue as a going concern. Our audited consolidated financial statements for the year ended December 31, 2022 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. 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.

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

We had an accumulated deficit of $296.2 million as of December 31, 2022 and an accumulated deficit of $306.9 as of June 30, 2023. We recorded net losses of $28.6 million, $16.2 million, and $16.8 million for the years ended December 31, 2022, 2021, and 2020, respectively. We recorded net losses of $4.9 million and $10.7 million for the three and six months ended June 30, 2023 and $5.6 million and $10.4 million for the three and six months ended June 30, 2022, 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.
