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 and nine months ended September 30, 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 and nine months ended September 30, 2021 and for the years ended December 31, 2020, 2019, and 2018.

As of September 30, 2021, the Company had working capital of approximately $39.2 million. The Company’s principal sources of liquidity as of September 30, 2021 consisted of approximately $33.6 million in cash, cash equivalents, and restricted cash, $3.6 million of net accounts receivable, and unused availability under the PMB Loan (as defined below) of approximately $2.8 million. As of December 31, 2020, the Company had working capital of approximately $23.9 million, $17.9 million in cash, cash equivalents and restricted cash and $3.1 million of net accounts receivable. The increase in cash, cash equivalents, and restricted cash since December 31, 2020 was primarily due to gross proceeds of $14.4 million from the issuance of common stock and $16.6 million from warrants exercised in the nine months ended September 30, 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 severely impacted global economic activity, and many countries and many states in the United States 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 were less than anticipated. Given the uncertainties regarding the

ongoing and future effects of COVID-19, there is no assurance that sales will return to normal levels during the remainder of 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.

The Company analyzed the provisions of the CARES Act and determined that it will not have a material impact on its future financial condition, results of operations, or liquidity, other than approximately $1.8 million received as part of the Employee Retention Credit.
