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, 2020 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 consolidated results of operations for the three months ended March 31, 2021 are not necessarily indicative of the results for the full year. The accompanying consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the fiscal year ended December 31, 2020, included in BIOLASE’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020 filed with the Securities and Exchange Commission (the “SEC”) on March 31, 2021 (the “2020 Form 10-K”).

Liquidity and Management’s Plans

The Company incurred losses from operations and used cash in operating activities for the three months ended March 31, 2021 and for the years ended December 31, 2020, 2019, and 2018.

As of March 31, 2021, the Company had working capital of approximately $46.5 million. The Company’s principal sources of liquidity as of March 31, 2021 consisted of approximately $41.0 million in cash, cash equivalents, and restricted cash, and $3.3 million of net accounts receivable. The increase in cash, cash equivalents, and restricted cash since December 31, 2020 was primarily due to proceeds of $14.4 million from the issuance of common stock and $16.5 million from warrants exercised in the first quarter of 2021. See Note 4 to the consolidated financial statements for additional information on these common stock issuances and warrant exercises.

Additional capital requirements may depend on many factors, including, among other things, the rate at which the Company’s business grows, the COVID-19 pandemic and the actions taken to contain it, demands for working capital, manufacturing capacity, and any acquisitions that the Company may pursue. From time to time, the Company could be required, or may otherwise attempt, 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.

COVID-19 Risk and Uncertainties and CARES Act

The COVID-19 pandemic has severely impacted global economic activity, and many countries and many states in the United States have reacted to the COVID-19 pandemic by instituting quarantines, mandating business and school closures and restricting travel. These mandated business closures included dental office closures worldwide, in large part, for all but emergency procedures. The ability of the Company’s salespeople to call on dental customers during these closures was greatly limited. In addition, most dental shows and workshops scheduled in 2020 were canceled. As a result of reduced sales due to the COVID-19 pandemic and

actions taken to contain it, cash generated from the Company’s operations during 2020 continued to be less than anticipated. Moreover, there is no assurance that sales will return to normal levels during 2021 or at any time thereafter.

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act") was signed into law. The CARES Act, among other things, includes provisions relating to refundable payroll tax credits, deferment of employer-side social security payments, net operating loss carryback periods, alternative minimum tax credit refunds, modifications to the net interest deduction limitations, increased limitations on qualified charitable contributions, and technical corrections to tax depreciation methods for qualified improvement property.

As of the date of issuance of these financial statements, the Company has not yet determined any future impact that the CARES Act will have on the Company’s financial condition, results of operations, or liquidity.

NOTE 2—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates

The preparation of these consolidated financial statements in conformity with generally accepted accounting principles in the United States of America (“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 as discussed in the Company’s 2020 audited financial statements included in the 2020 Form 10-K. Management believes that there have been no significant changes during the three months ended March 31, 2021 in the Company’s critical accounting policies from those disclosed in the Company’s 2020 audited financial statements included in the 2020 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, restricted cash, accounts receivable, accounts payable, accrued liabilities, and the SWK Loan (as defined below) as discussed in Note 9, approximate fair value because of the nature of these items.

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, restricted cash, and trade accounts receivable. The Company maintains its cash and cash equivalents and restricted cash 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 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-month periods ended March 31, 2021 and 2020, 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 2019, the FASB issued ASU 2019-12, Income Taxes – Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by clarifying and amending existing guidance related to the recognition of franchise tax, the evaluation of a step-up in the tax basis of goodwill and the effects of enacted changes in tax laws or rates in the effective tax rate computation, among other clarifications. ASU 2019-12 is effective for annual periods beginning after December 15, 2020, including interim periods within those fiscal years, and early adoption is permitted. The Company adopted this guidance effective January 1, 2021, and the adoption of this standard did not have a material impact on its consolidated financial statements.

In August 2020, the FASB issued ASU 2020-06, Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40). This ASU reduces the number of accounting models for convertible debt instruments and convertible preferred stock and amends the guidance for the derivatives scope exception for contracts in an entity’s own equity to reduce form-over-substance-based accounting conclusions. In addition, this ASU improves and amends the related earnings per share guidance. This standard is effective for the Company beginning on January 1, 2022, with early adoption permitted only in the first quarter of 2021. Adoption is either a modified retrospective method or a fully retrospective method of transition. The Company is currently assessing the impact the new guidance will have on its consolidated financial statements.

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 standard will be effective for the Company beginning January 1, 2023, with early adoption permitted beginning January 1, 2019. The Company is currently assessing the impact that adopting this new accounting standard will have 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 expense.

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 74% of net revenue for the three months ended March 31, 2021 and March 31, 2020, 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 26% of net revenue for the three months ended March 31, 2021 and March 31, 2020, 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 $0.7 million as of each of March 31, 2021 and December 31, 2020.

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):

NOTE 4—REDEEMABLE PREFERRED STOCK AND STOCKHOLDERS’ EQUITY

BIOLASE's board of directors (the "Board"), without further stockholder authorization, may issue from time to time up to 1,000,000 shares of the Company’s preferred stock. Of the 1,000,000 shares of preferred stock, 69,565 shares are designated as Series E Participating Convertible Preferred Stock, par value $0.001 per share (“Series E Preferred Stock”), and 18,000 shares are designated as Series F Convertible Preferred Stock, par value $0.001 per share (“Series F Preferred Stock”).

Common Stock

On February 10, 2021, BIOLASE issued and sold in an underwritten bought deal offering an aggregate of 14,000,000 shares of common stock at a price of $1.03 per share less underwriting discounts and commissions (the "Equity Offering"). The Company received gross proceeds of approximately $14.4 million before deducting underwriting discounts and commissions and estimated offering expenses of $1.1 million.

Preferred Stock

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 and 45,000,000 warrants (the “July 2020 Warrants”), with each warrant exercisable for one share 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 is 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 $0.40 per share. Each share of Series F Preferred Stock is convertible into 2,500 shares of common stock, and each July 2020 Warrant entitles the holder thereof to purchase one share BIOLASE common stock at a conversion price of $0.40 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, and upon conversion of approximately 17,000 Series F Preferred Stock to common stock, this discount was accreted and also recognized as a deemed dividend to preferred stockholders in the amount of $0.5 million and $14.7 million for the three months ended March, 31, 2021 and the year ended December 31, 2020, respectively.

Approximately 268 and 882 shares of Series F Preferred Stock remained outstanding as of March 31, 2021 and December 31, 2020, respectively.

Redeemable Preferred Stock

Series E Participating Convertible Preferred Stock

As of March 31, 2021 and December 31, 2020, there were no shares of Series E Preferred Stock issued and outstanding.

As of March 31, 2021, a total of 3,110,000 shares have been authorized for issuance under the 2002 Plan, of which 1,036,171 shares of common stock have been issued pursuant to options that were exercised, 971,735 shares of common stock have been reserved for options and restricted stock units ("RSUs") that are outstanding, and 0 shares of common stock remain available for future grants.

2018 Stock Incentive Plan

At the 2018 annual meeting of stockholders, the Company’s stockholders approved the 2018 Long-Term Incentive Plan (as amended, the “2018 Plan”) which was amended by Amendment No. 1 to the 2018 Plan, approved by the Company’s stockholders at a special meeting on September 21, 2018 and Amendment No. 2 to the 2018 Plan, as approved by the Company’s stockholders on May 15, 2019 and Amendment No. 3 to the 2018 Plan, as approved by the Company’s stockholders on May 13, 2020. 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.

Subject to the terms and conditions of the 2018 Plan, the number of shares authorized for grants under the 2018 Plan is 12,221,101. As of March 31, 2021, a total 5,745,827 shares of the Company’s common stock have been reserved for issuance upon the exercise of outstanding options and or settlement of unvested RSUs, and 1,812,307 shares of the Company’s common stock remain available for future grants.

Net Loss Per Share – Basic and Diluted

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

Outstanding stock options, RSUs, and warrants to purchase approximately 25,290,000 and 3,400,000 shares were not included in the calculation of diluted loss per share amounts for the periods ended March 31, 2021 and March 31, 2020, respectively, as their effect would have been anti-dilutive. Also excluded in the calculation of diluted loss per share amount for the three months ended March 31, 2021, are the 670,000 shares of BIOLASE common stock issuable upon conversion of the 268 shares of Series F Preferred Stock outstanding as of March 31, 2021.

NOTE 7—INTANGIBLE ASSETS AND GOODWILL

The Company conducted its annual impairment test of goodwill as of December 31, 2020 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. No events have occurred since December 31, 2020 through the date of these unaudited consolidated financial statements that would trigger further impairment testing of the Company’s intangible assets and goodwill.

Lines of Credit

Pacific Mercantile Bank

On October 28, 2019, the Company entered into a loan and security agreement (the “Loan Agreement”) with Pacific Mercantile Bank, as lender (“PMB”), which provides for a revolving line of credit (the “PMB Loan”) in a maximum principal amount not to exceed the lesser of (i) $3 million or (ii) the sum of 90% of the Eligible Accounts (as defined in the Loan Agreement) plus 75% of the Eligible Inventory (as defined in the Loan Agreement, and subject to certain limitations set forth therein); provided that the maximum principal amount of the PMB Loan may be reduced from time to time in PMB’s good faith business judgment as set forth in the Loan Agreement. Borrowings under the PMB Loan may be used for working capital. The PMB Loan matures on October 28, 2021, unless earlier terminated.

The Company’s obligations under the PMB Loan are secured by a security interest in substantially all of the Company’s property. No borrowings may be made under the PMB Loan Agreement unless and until Exim Bank agrees to guarantee the PMB Loan and the Company has entered into a borrower agreement with Exim Bank.

Borrowings under the PMB Loan bear interest at a daily rate equal to the prime rate published in the Wall Street Journal, plus 1.5% per annum; provided, that the interest rate in effect on any day shall not be less than 6.0% per annum. Additionally, the Company is required to pay an initial and annual fee of $52,500 to Exim Bank.

The PMB Loan Agreement requires the Company to maintain unrestricted cash at PMB plus unused availability under the PMB Loan in an amount equal to at least the Burn Rate. “Burn Rate” means the Company’s net profit/net loss plus depreciation plus amortization plus stock-based compensation, measured on a trailing three-month basis. In addition, the PMB Loan Agreement contains customary affirmative and negative covenants for financings of its type (subject to customary exceptions).

As of March 31, 2021 and December 31, 2020, the Company had no borrowings outstanding and unused availability under the PMB Loan of approximately $2.2 million and $2.3 million, respectively.

Term Loan

On November 9, 2018, the Company entered into a five-year secured Credit Agreement (the “Credit Agreement”) with SWK Funding LLC (“SWK”), pursuant to which the Company has borrowed $14.3 million (“SWK Loan”) as of March 31, 2021. 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 2020 Form 10-K, repayment of the SWK Loan is interest-only through the second quarter of 2022, paid quarterly with the option to extend the interest-only period. Principal repayments begin in the second quarter of 2022 and will be approximately $0.7 million quarterly until the SWK Loan matures in the second quarter of 2024. The loan bears interest at LIBOR plus 10% or another index that approximates LIBOR as close as possible if and when LIBOR no longer exists.

In light of the Company's increase in working capital from the Equity Offering and cash received from warrants exercised, the Company entered into the Seventh Amendment to the Credit Agreement (the “Seventh Amendment”) with SWK on February 24, 2021, which provides for adjusted minimum aggregate revenue and EBITDA requirements at the end of certain periods, to the extent that our liquid assets are less than $15 million. While the Company's liquid assets are at or above $15 million, no additional financial maintenance covenants are applicable.

For the Seventh Amendment, the Company paid an incremental amendment fee of $25,000, which is being amortized over the remaining life of the loan as of the date of the amendment.

As of March 31, 2021, the Company was in compliance with debt covenants of the Credit Agreement.

Paycheck Protection Program Loan

On April 14, 2020, the Company was granted a loan (the “PPP Loan”) under the Paycheck Protection Program from PMB in the aggregate amount of $2,980,000, pursuant to the Paycheck Protection Program under the CARES Act.

The PPP Loan, which was in the form of a note dated April 13, 2020 issued by BIOLASE, matures on April 13, 2022 and bears interest at a rate of 1.0% per annum. Interest is payable monthly commencing on November 1, 2020. The note may be prepaid at any time prior to maturity with no prepayment penalties. Funds from the PPP Loan may only be used for payroll costs, costs used to continue group health care benefits, mortgage payments, rent, utilities, and interest on other debt obligations incurred before February 15, 2020. The Company recorded the principal amount of approximately $3.0 million due on the PPP Loan in non current term loans in the consolidated balance sheet as of March 31, 2021 and December 31, 2020. Interest on the PPP Loan was not material. The Company believes it used the entire PPP Loan amount for qualifying expenses. Under the terms of the PPP, certain amounts of the PPP Loan may be forgiven if they are used for qualifying expenses as described in the CARES Act.

In July 2020, the Company amended the provisions of the PPP Loan. The amendment modifies the original payment deferment period from six months to the date that the United States Small Business Administration (“SBA") remits the Company’s loan forgiveness to PMB or if no forgiveness is requested to ten months after the end of the 24-week measurement period. The amendment also increased the amount of non-payroll costs eligible for loan forgiveness from 25% to 40%. During 2020, the Company requested forgiveness in accordance with the application requirements. As of the date of this filing, the Company has not received a reply to its request, and there can be no assurance that the PPP Loan will be forgiven.

EIDL Loan

On May 22, 2020, the Company executed the standard loan documents required for securing a loan (the “EIDL Loan”) from 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 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.

Western Alliance Warrants

On March 6, 2018, the Company issued to Western Alliance warrants (the “Original Western Alliance Warrants”) to purchase up to the number of shares of common stock equal to $120,000 divided by the applicable exercise price at the time such warrants are exercised. The Original Western Alliance Warrants are fully vested and exercisable. The Original Western Alliance Warrants may be exercised with a cash payment from Western Alliance, or, in lieu of a cash payment, Western Alliance may convert the warrants into a number of shares, in whole or in part. The initial exercise price of the warrants was $2.35 per share. On September 27, 2018, the Company entered into the Second Modification Agreement to amend the Original Business Financing Agreement. In connection with

the Second Modification Agreement, the Original Western Alliance Warrants were terminated, and the Company issued new warrants (the “Western Alliance Warrants”) to purchase up to the number of shares of common stock equal to $120,000 divided by the exercise price of $2.13, which was the closing price of the Company’s common stock on September 27, 2018. The Western Alliance Warrants are immediately exercisable and expire on September 27, 2028. These warrants contain down-round features that require the Company to adjust the exercise price proportionately should the Company issue shares at a price per share less than the exercise price. The sale of common stock in the second quarter of 2020 triggered an adjustment to the exercise price to approximately $0.60 per share. The impact of the adjustment to the exercise price was not material.

SWK Warrants

In connection with the Credit Agreement, on November 9, 2018, the Company issued to SWK warrants (the “SWK Warrants”) to purchase up to 372,023 shares of BIOLASE common stock. The SWK Warrants were immediately exercisable and expire on November 9, 2026. The exercise price of the SWK Warrants is $1.34, which was the average closing price of BIOLASE common stock for the ten trading days immediately preceding November 9, 2018. These warrants contain down-round features that require the Company to adjust the exercise price proportionately should the Company issue shares at a price per share less than the exercise price. The fair value of the SWK Warrants was estimated using the Black-Scholes option-pricing model with the following assumptions: expected term of 8 years; volatility of 81.79%; annual dividend per share of $0.00; and risk-free interest rate of 3.13%; and resulted in an estimated fair value of $0.4 million.

In November 2019, these warrants were consolidated and the exercise price was adjusted to $1.00, and in March 2020, the exercise price was adjusted a second time to $0.49. The impact of both reprice events was de minimis to the consolidated financial statements. In connection with the Fifth Amendment, the Company entered into a Third Amendment to the SWK Warrant Agreement. Under this amendment, the Company granted to SWK 63,779 additional common stock warrants at an exercise price of approximately $0.39198. All other terms and conditions to the additional warrants were the same as those previously granted. The Company also revised the exercise price of the 487,198 common stock warrants held by SWK to $0.39198. The Company measured the fair value of the 63,779 warrants granted using the Black-Scholes. The fair value of the additional warrants and the aggregate impact of the exercise price adjustments in previous amendments to the Warrant Agreement were less than $0.1 million and not material to the consolidated financial statements. Due to the repricing that occurred in the second quarter of 2020, the down round features of these warrants was not triggered by the Company’s June 2020 sale of common stock.

DPG Warrants

In connection with the SWK Loan, the Company paid a finder’s fee to Deal Partners Group of $0.4 million cash and issued warrants to purchase up to 279,851 shares of common stock (the “DPG Warrants”). The DPG Warrants were issued on November 14, 2018, were exercisable immediately, and expire on November 9, 2026. The exercise price of the DPG Warrants is $1.34 which was the average closing price of the Company’s common stock for the ten trading days immediately preceding November 9, 2018. These warrants contain down-round features that require the Company to adjust the exercise price proportionately should the Company issue shares at a price per share less than the exercise price. The fair value of the DPG Warrants of $0.3 million was estimated using the Black-Scholes option pricing model with the following assumptions: expected term of 8 years; volatility of 81.79%; annual dividend per share of $0.00; and risk-free interest rate of 3.13%. In November 2019, the exercise price of the DPG Warrants issued on November 9, 2018 was adjusted from $1.34 per share to $0.8767 per share and the exercise price of the DPG Warrants issued on May, 2019 was adjusted from $2.17 per share to $1.4197 per share. The impact of the reprice was de minimis to the unaudited consolidated financial statements. The June 2020 sale of common stock triggered the down round features of these warrants, and in August 2020, the Company adjusted the exercise price of these warrants to $0.62 and $0.38 per share. The impact of this reprice was not material.

The value of both the SWK Warrants and the DPG Warrants was recognized as a discount on the SWK Loan and is being amortized on a straight-line basis which approximates the effective-interest method, over the loan term of five years. Additionally, based on the adoption of ASU 2017-11 in the fourth quarter of 2018, these warrants are classified as equity in the consolidated balance sheet as of March 31, 2021 and December 31, 2020.

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. The Company leases its 11,000 square foot corporate headquarters pursuant to a lease that expires on December 31, 2025 and leases a manufacturing facility located in Corona, California, which expires on June 30, 2025.

NOTE 11— COMMITMENTS AND CONTINGENCIES

On April 24, 2012, CAO Group, Inc. (“CAO”) filed a lawsuit against BIOLASE in the District of Utah alleging that BIOLASE’s ezlase dental laser infringes on U.S. Patent No. 7,485,116 (the “116 Patent”). On September 9, 2012, CAO amended its complaint, adding claims for (1) business disparagement/injurious falsehood under common law and (2) unfair competition under 15 U.S.C. Section 1125(a). The additional claims stem from a press release that BIOLASE issued on April 30, 2012, which CAO claims contained false statements that are disparaging to CAO and its diode product. The amended complaint sought injunctive relief, treble damages, attorneys’ fees, punitive damages, and interest. Until January 24, 2018, this lawsuit was stayed in connection with United States Patent and Trademark Office proceedings relating to the 116 Patent, which proceedings ultimately culminated in a January 27, 2017 decision by the United States Court of Appeals for the Federal Circuit, affirming the findings of the Patent Trial and Appeal Board, which were generally favorable to the Company. On January 25, 2018, CAO moved for leave to file a second amended complaint to add certain claims, which filing the Company is not opposing.

On January 23, 2018, CAO filed a lawsuit against BIOLASE in the Central District of California alleging that BIOLASE’s diode lasers infringe on U.S. Patent Nos. 8,337,097, 8,834,497, 8,961,040 and 8,967,883. The complaint seeks injunctive relief, treble damages, attorneys’ fees, punitive damages, and interest.

On January 25, 2019 (the “Effective Date”), BIOLASE entered into a settlement agreement (the “CAO Settlement Agreement”) with CAO. Pursuant to the CAO Settlement Agreement, CAO agreed to dismiss with prejudice the lawsuits filed by CAO against the Company in April 2012 and January 2018. In addition, CAO granted to the Company and its affiliates a non-exclusive, non-transferable (except as provided in the CAO Settlement Agreement), royalty-free, fully-paid, worldwide license to the licensed patents for use in the licensed products and agreed not to sue the Company, its affiliates or any of its manufacturers, distributors, suppliers or customers for use of the licensed patents in the licensed products, and the parties agreed to a mutual release of claims. The Company agreed (i) to pay to CAO, within five days of the Effective Date, $500,000 in cash, (ii) to issue to CAO, within 30 days of the Effective Date, 500,000 restricted shares of common stock of the Company (the “Stock Consideration”), and (iii) to pay to CAO, within 30 days of December 31, 2021, an amount in cash equal to the difference (if positive) between $1,000,000 and the value of the Stock Consideration on December 31, 2021. The Stock Consideration vests and becomes transferrable on December 31, 2021, subject to the terms of a restricted stock agreement entered into between the parties. The Company considered this a Type I subsequent event and recognized a $1.5 million contingent loss on patent litigation settlement in its statement of operations for the year ended December 31, 2018. In January 2019, the Company paid CAO $500,000 in cash. On January 31, 2019, the case was dismissed with prejudice. During the three-month period ended March 31, 2019, the Company recorded an additional loss on patent litigation of $0.2 million which represented the change in fair value of the restricted stock to be issued to CAO at March 31, 2019. Subsequent to March 31, 2019, the Company reversed the additional loss commensurate with the fluctuations in the Company’s share price. In August 2020, the Company signed a Letter Agreement to terminate the Manufacturing Agreement and purchase from CAO raw materials and other inventory held by CAO as part of the original CAO Settlement Agreement.

In February 2021, the Company issued 500,000 restricted shares of common stock in satisfaction of its obligation to issue the Stock Consideration to CAO under the CAO Settlement Agreement and reduced the accrued liability to $0.6 million. As of March 31, 2021, the remaining accrued liability related to the CAO Settlement Agreement was included in current accrued liabilities in the amount of $0.6 million. As of December 31, 2020, the accrued liability related to the CAO Settlement Agreement was $1.0 million and was included in non current other liabilities.

NOTE 12—SEGMENT INFORMATION

The Company currently operates in a single business segment. Management uses one measurement of profitability and does not segregate its business for internal reporting. For the three months ended March 31, 2021 and 2020, sales to customers in the United States accounted for approximately 64% and 65% of net revenue and international sales accounted for approximately 36% and 35% of net revenue, respectively. No individual country, other than the United States, represented more than 10% of total net revenue during the three months ended March 31, 2021 or 2020.

No individual customer represented more than 10% of the Company’s revenue for the three months ended March 31, 2021 or 2020.

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 March 31, 2021 and December 31, 2020.

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 14—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 months ended March 31, 2021 and 2020. 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 months ended March 31, 2021 and 2020, the Company recorded an income tax provision of $60,000 and a benefit of $19,000 resulting in an effective tax rate of 0.9% and 0.2%, respectively. The income tax provisions for the three months

ended March 31, 2021 and 2020 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 15—SUBSEQUENT EVENTS

In April 2021, the Company was notified that installment payments, including principal and interest, related to the EIDL Loan are due monthly beginning 24 months from the date of the EIDL Loan or July 2022, rather than monthly beginning 12 months from the date of the EIDL Loan or July 2021.

Overview

We are 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, 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 and generate more patient referrals.

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 the

only effective, safe solution to preserving sick implants. In addition, Waterlase disinfects root canals more efficiently than some traditional chemical methods. We also offer our diode laser systems to perform soft tissue, pain therapy, and cosmetic procedures, including teeth whitening. We have approximately 271 issued and 40 pending United States and international patents, the majority of which are related to Waterlase technology. From 1998 through December 31, 2020, we sold over 41,200 laser systems in over 80 countries around the world. Contained in this total are approximately 13,600 Waterlase systems, including over 9,100 Waterlase MD, MDX, Express and iPlus systems.

Consistent with our goal to focus our energies on strengthening our leadership, and worldwide competitiveness and increasing the amount of attention we pay to our professional customers and their patients, we have made strategic personnel additions to our senior management team.

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.

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 systems, we sell teeth whitening gel kits.

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.

During the first quarter of 2021, the Company experienced revenue growth of 70%, compared to the first quarter of 2020, primarily due to high demand from new users for its dental lasers. The Company is currently forecasting revenue for the second quarter ending June 30, 2021 to be significantly above the year-ago second quarter, which was the quarter most impacted by COVID-19. Although there are signs of recovery from the impact of COVID-19 both domestically and internationally, no assurance can be provided that the favorable trends will continue.

To further accelerate our growth, over the past six months, we have formed specialist academies focused on expanding awareness of the benefits of our dental lasers into dental specialist communities. During the second quarter of 2021, we launched the Waterlase Pediatric Dental Academy (the "WPDA") for pediatric dentists. This academy will provide clinicians with an immersive training experience through peer-led learning, best practice sharing, and ongoing mentorship to help ensure optimal integration of Waterlase technology into clinical practices. During the first quarter of 2021, we also launched an innovative and first-of-its-kind program in the periodontal community. This program fosters peer-led learning about dental lasers and an ongoing mentorship from leading clinicians, featuring online meetings and case reviews by experts in the field. Additionally, during the first quarter of 2021, we launched the Waterlase Endo Academy, an exclusive community of leading endodontists dedicated to improving patient outcomes and profitability with new technology, and announced a collaboration with Einstein Healthcare Network’s Residency in Endodontics to train endodontics residents in the use of Waterlase dental lasers.

In April 2021, we also announced plans to develop a new EdgePRO laser-assisted microfluidic irrigation device for endodontists with EdgeEndo, a global leader in commercializing endodontic products. The new microfluidic irrigation device is being developed to offer a solution to endodontists seeking more from their current cleaning and disinfecting techniques. The EdgePRO will be built upon BIOLASE’s patented and proven platform that has been shown to significantly improve debridement, cleaning, and disinfection by up to 99% using the most advanced laser light sound technology.

Recent Developments

Impact of Coronavirus (COVID-19) on Our Operations

In December 2019, a novel strain of coronavirus was reported to have surfaced in Wuhan, China. The novel coronavirus spread to over 100 countries, including every state in the United States. On March 11, 2020, the World Health Organization declared COVID-19, the disease caused by the novel coronavirus, a pandemic, and on March 13, 2020, the United States declared a national emergency with respect to the coronavirus outbreak. This outbreak severely impacted global economic activity, and many countries and many states in the United States have reacted to the outbreak by instituting quarantines, mandating business and school closures and restricting travel. These mandated business closures included dental office closures in Europe and the United States for all but emergency procedures. Our salespeople were unable to call on dental customers during these closures. In addition, most dental shows and workshops scheduled in 2020 were canceled. There is no assurance that the Company’s sales will return to normal levels during 2021 or at any time thereafter. See Item 1A — “Risk Factors” for additional information regarding the potential impact of the COVID-19 pandemic on our business, results of operations and financial condition.

SWK Loan Amendment

In light of the Company's increase in working capital from the Equity Offering (as defined below) and cash received from warrants exercised, we entered into the Seventh Amendment to the Credit Agreement (the “Seventh Amendment”) with SWK Funding LLC on February 24, 2021, which provides for adjusted minimum aggregate revenue and EBITDA requirements at the end of certain periods, to the extent that the Company's liquid assets are less than $15 million. As amended, the Credit Agreement provides that while the Company's liquid assets are at or above $15 million, no additional financial maintenance covenants are applicable.

Equity Offering

On February 10, 2021, BIOLASE issued and sold in an underwritten bought deal offering an aggregate of 14,000,000 shares of common stock at a price of $1.03 per share less underwriting discounts and commissions. The Company received gross proceeds of approximately $14.4 million before deducting underwriting discounts and commissions and estimated offering expenses of $1.1 million. The Company intends to use the aggregate net proceeds of the offering primarily for working capital and general corporate purposes.

Resignation of President and Chief Executive Officer, and Director

On February 22, 2021, Todd Norbe resigned as President and Chief Executive Officer of BIOLASE, and resigned as a member of the Company's board of directors (the "Board").

Appointment of President and Chief Executive Officer

Effective February 23, 2021, the Board appointed John R. Beaver President and Chief Executive Officer of the Company. Mr. Beaver was most recently the Company’s Executive Vice President, Chief Operating Officer and Chief Financial Officer. He joined BIOLASE in 2017 as Senior Vice President and Chief Financial Officer. He assumed roles of varying responsibilities over the past few years, including Interim Chief Executive Officer of BIOLASE from April 2017 until the hiring of Mr. Norbe.

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 2020 Form 10-K. There have been no significant changes during the three months ended March 31, 2021 in our critical accounting policies from those disclosed in Item 7 of the 2020 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. In 2019, we revised our non-GAAP financial measures to include the change in allowance for doubtful accounts in an effort to better align Adjusted EBITDA with our loan covenants and how management evaluates business 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, patent litigation settlements, stock-based compensation, 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 March 31, 2021 and 2020, as well as the amount of change and percentage of change in each geographic revenue category, (dollars in thousands):


	Three Months Ended				Three Months Ended
	March 31,				March 31,				Amount		Percent
	2021				2020				Change		Change
United States	$	5,221	64.3	%	$	3,129	65.4	%	$	2,092		66.9	%
International		2,895	35.7	%		1,654	34.6	%		1,241		75.0	%
Net revenue	$	8,116	100.0	%	$	4,783	100.0	%	$	3,333		69.7	%

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.

Total net revenue increased by $3.3 million, or 70%, during the three months ended March 31, 2021 as compared to the same period in 2020 primarily due to worldwide dental office closures in 2020 as a result of the global COVID-19 pandemic. In the U.S., net revenue increased by $2.1 million, or 67%, for the three months ended March 31, 2021 compared to the same period in 2020.

Outside the U.S., net revenue increased by $1.2 million, or 75%, during the three months ended March 31, 2021 as compared to the same period in 2020. We believe dental offices in the U.S. are beginning to return to prior patient volume resulting in better revenue results, while patient volume in many countries outside the U.S. are still lagging from their pre-COVID-19 levels.

Cost of Revenue and Gross Profit: The following table summarizes our unaudited cost of revenue and gross profit for the three months ended March 31, 2021 and 2020, as well as the amount of change and percentage of change (dollars in thousands):


	Three Months Ended				Three Months Ended
	March 31,				March 31,				Amount		Percent
	2021				2020				Change		Change
Net revenue	$	8,116	100.0	%	$	4,783	100.0	%	$	3,333		69.7	%
Cost of revenue		5,375	66.2	%		3,430	71.7	%		1,945		56.7	%
Gross profit	$	2,741	33.8	%	$	1,353	28.3	%	$	1,388		102.6	%

Gross profit as a percentage of revenue typically fluctuates with product and regional mix, selling prices, product costs and revenue levels. Gross profit for the three months ended March 31, 2021, was $2.7 million, or 34% of net revenue, an increase of approximately $1.4 million, or 103%, as compared with gross profit of $1.4 million, or 28% of net revenue, for the same period in 2020. The 6% increase in gross profit reflects the impact of the increase in revenues from the COVID-19 pandemic combined with an increase in average selling prices for products sold in the U.S. during first quarter of 2021 compared to the same period in 2020.

Operating Expenses: The following table summarizes our unaudited operating expenses (including as a percentage of net revenue) for the three months ended March 31, 2021 and 2020, as well as the amount of change and percentage of change (dollars in thousands):


	Three Months Ended				Three Months Ended
	March 31,				March 31,				Amount		Percent
	2021				2020				Change		Change
Sales and marketing	$	3,553	43.8	%	$	2,704	56.5	%	$	849		31.4	%
General and administrative		3,447	42.5	%		3,010	62.9	%		437		14.5	%
Engineering and development		1,803	22.2	%		991	20.7	%		812		81.9	%
Total operating expenses	$	8,803	108.5	%	$	6,705	140.2	%	$	2,098		31.3	%

Sales and Marketing Expense. Sales and marketing expenses during the three months ended March 31, 2021 increased by $0.8 million, or 31%, as compared to the same period in 2020. This increase is primarily due to $0.5 million in bonus incentives for achieving sales targets, $0.2 million in sales commissions, $0.2 million in increased advertising expenses, and $0.2 million in various other expenses, partially offset by $0.3 million in reduced travel and trade show related expenses from the impact of the COVID-19 pandemic on our business operations.

General and Administrative Expense. General and administrative expenses during the three months ended March 31, 2021 increased by $0.4 million, or 15%, compared to the same period in 2020, primarily due to $0.4 million in severance expense, $0.3 million from a special shareholders meeting scheduled to be held in the first quarter of 2021, $0.3 million in legal and audit fees, $0.3 million in leadership bonus awards, and $0.2 million in various other expenses. These increases are partially offset by $1.1 million in lower allowance for doubtful accounts expense.

Engineering and Development Expense. Engineering and development expenses during the three months ended March 31, 2021 increased by $0.8 million, or 82%, compared to the same period in 2020, primarily due to an increase in payroll expenses driven by an increase in engineering projects for 2021 as compared to 2020. Although our primary focus will be on our sales and marketing efforts, we expect to continue our investment in engineering and development activity in the remainder of 2021.

Non-Operating Loss

Loss on Foreign Currency Transactions. We realized a $0.2 million loss on foreign currency transactions during the three months ended March 31, 2021 compared to a $0.1 million loss on foreign currency transactions during the three months ended March 31, 2020, 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 March 31, 2021 and was consistent with the same period in 2020. We expect interest expense to fluctuate depending on the movement in the London Interbank Bank Offered Rate (“LIBOR”) through the remainder of 2021 and the outstanding balance of our revolving line of credit with Pacific Mercantile Bank (the "PMB Loan"), if any.

Income Tax Provision (Benefit). We use a discrete year-to-date method in calculating quarterly provision for income taxes. Our provision for income taxes was a expense of $60 thousand for the three months ended March 31, 2021 as compared to a benefit of $19 thousand for the same period in the prior year. For additional information regarding income taxes, see Part I, Item I, Note 14 – Income Taxes.

Net Loss. For the reasons stated above, our net loss totaled approximately $6.9 million for the three months ended March 31, 2021 compared to a net loss of $6.0 million for the three months ended March 31, 2020.

Liquidity and Capital Resources

At March 31, 2021, we had approximately $41.0 million in cash, cash equivalents and restricted cash. Management defines cash and cash equivalents as highly liquid deposits with original maturities of 90 days or less when purchased. The increase in cash, cash equivalents, and restricted cash was primarily due to proceeds of $14.4 million from the issuance of common stock and $16.5 million from warrants exercised during the first quarter of 2021 and fourth quarter of 2020.

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


	Three Months Ended
	March 31,
	2021			2020
Net cash flows used in operating activities	$	(6,499	)	$	(4,134	)
Net cash flows used in investing activities		(8	)		(9	)
Net cash flows provided by (used in) financing activities		29,825			(117	)
Effect of exchange rate changes		(148	)		(18	)
Net change in cash, cash equivalents and restricted cash	$	23,170		$	(4,278	)

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 three months ended March 31, 2021 totaled $6.5 million and was primarily comprised of our net loss of $6.9 million and a net decrease in operating assets and liabilities of $1.1 million, partially offset by stock-based compensation expense of $0.9 million. The net decrease in our operating assets and liabilities was primarily due to a $0.7 million increase in inventory and a decrease in accounts payable and accrued liabilities of $0.5 million, partially offset by a $0.6 million decrease in prepaid expenses and other current assets.

Investing Activities

Cash used in investing activities for the three months ended March 31, 2021 was minimal. We expect cash flows from investing activities to remain minimal through the remainder of 2021.

Financing Activities

Net cash provided by financing activities for the three months ended March 31, 2021 was approximately $29.8 million primarily due to the sale of common stock from our February 2021 equity offering and the exercise of common stock warrants described below.

Effect of Exchange Rate

The $0.1 million effect of exchange rate on cash for the three months ended March 31, 2021 was due to recognized loss on foreign currency transactions, primarily driven by changes in the Euro during the period.

Future Liquidity Needs

As of March 31, 2021, we had working capital of approximately $46.5 million. Our principal sources of liquidity as of March 31, 2021 consisted of approximately $41.0 million in cash, cash equivalents and restricted cash and $3.3 million of net accounts receivable and any availability under our PMB Loan.

Although the Company received gross proceeds of approximately $14.4 million from an equity offering in February 2021 and $16.5 million for warrant exercises subsequent to December 31, 2020, the Company may still have 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, the COVID-19 pandemic and the actions taken to contain it, demands for working capital, manufacturing capacity, and any acquisitions that the Company may pursue. From time to time, the Company could be required, or may otherwise attempt, 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.

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.

We intend 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.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

In the ordinary course of business, we may periodically become subject to legal proceedings and claims arising in connection with ongoing business activities. The results of litigation and claims cannot be predicted with certainty, and unfavorable resolutions are possible and could materially and adversely affect our results of operations, cash flows and financial position. In addition, regardless of the outcome, litigation could have an adverse impact on us because of defense costs, diversion of management resources and other factors. While the outcome of such proceedings and claims cannot be predicted with certainty, there are no matters, as of March 31, 2021, that, in the opinion of management, will have a material adverse effect on our financial position, results of operations or cash flows.

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 2020 Form 10-K. The risks and uncertainties described below and in the 2020 Form 10-K 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.

Failure to meet the continued listing requirements of the NASDAQ Stock Market, LLC (“NASDAQ”) 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.

We have received deficiency letters from NASDAQ in the past. For example, on December 3, 2019, we received a deficiency letter from NASDAQ’s Listing Qualifications Department (the “Staff”), notifying us that we violated the continued listing requirements of NASDAQ listing rule 5550(a)(2) (the “Minimum Bid Price Rule”), which requires that BIOLASE common stock maintain a minimum bid price of at least $1.00 per share. On March 31, 2020, we received a deficiency letter from NASDAQ notifying us that, based on the Company’s stockholders’ equity of $377,000 as of December 31, 2019, as reported in our Form 10-K for the fiscal year ended December 31, 2019, we were no longer in compliance with the minimum stockholders’ equity requirement for continued listing on NASDAQ under NASDAQ Listing Rule 5550(b)(1), which requires listed companies to maintain stockholders’ equity of at least $2.5 million.

As of the date of this quarterly report on Form 10-Q, the market price of BIOLASE common stock is below $1.00 per share. If we fail to comply with NASDAQ’s continued listing requirements, including the Minimum Bid Price Rule, we may receive another deficiency letter from the Staff, and if we do not regain compliance within the period specified in such deficiency letter, 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.

The Company has proposed an amendment to its certificate of incorporation to effect a reverse stock split of BIOLASE common stock, if and when determined by the Board. The Company’s stockholders will vote on the proposal at the Company's 2021 annual meeting of stockholders scheduled to be held on May 26, 2021. If the Company’s stockholders approve the reverse stock split, the Company expects to regain or maintain compliance with the Minimum Bid Price Rule for the foreseeable future. However, there is no assurance that the Company’s stockholders will approve the proposal.

Non-compliance with the objective and subjective criteria for the Paycheck Protection Program loan could have a material adverse effect on our business.

On April 14, 2020, BIOLASE obtained a loan (the “PPP Loan”) from Pacific Mercantile Bank in the aggregate amount of $2,980,000, pursuant to the Paycheck Protection Program under the CARES Act. On April 23, 2020, the Secretary of the United States Department of the Treasury stated that the Small Business Administration will perform a full review of any PPP loan over $2.0 million before forgiving the loan. In order to apply for the PPP Loan, we were required to certify, among other things, that the current economic uncertainty made the PPP Loan request necessary to support our ongoing operations. We made this certification in good faith after analyzing, among other things, the maintenance of our entire workforce, notwithstanding certain obvious “work-from-home” limitations associated with the nature of our business. We also took into account our need for additional funding to continue operations, and our ability to access alternative forms of capital in the then-current market environment. Following this analysis, we believe that we satisfied all eligibility criteria for the PPP Loan, and that our receipt of the PPP Loan is consistent with the objectives of the PPP of the CARES Act. If it is later determined that we were ineligible to receive the PPP Loan, we may be required to repay

the PPP Loan in its entirety and/or be subject to additional penalties and adverse publicity, which could have a material adverse effect on our business, results of operations, and financial condition.

We believe that we used the proceeds of the PPP Loan in a manner that will entitle us to full forgiveness.

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 approximately $258 million at March 31, 2021. We recorded net losses of approximately $6.9 million, $16.8 million, $17.9 million, and $21.5 million for the three months ended March 31, 2021 and the years ended December 31, 2020, 2019, and 2018, 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.
