On January 29, 2024, BIOLASE, Inc. (the “Company”) issued a press release announcing certain preliminary unaudited revenue results for the fiscal year ended December 31, 2023, a recap of the Company’s 2023 key accomplishments, and anticipated operational and product milestones for 2024. The Company is updating that information with the following preliminary information regarding net operating loss: full-year 2023 net operating loss is expected to be in the range of $17 million to $20 million, achieving 21% to 33% improvement over 2022 as cost-saving initiatives announced during the second quarter ended June 30, 2023 were realized, including an approximate 20% reduction in the Company’s U.S. workforce, as well as decreased advertising, travel and trade-show related sales and marketing expenses and a decrease in legal and consulting for general and administrative expenses.

The estimated range of net operating loss for 2023 is preliminary and unaudited, represents management’s estimate as of the date of this Current Report on Form 8-K and is subject to completion of the Company’s financial closing procedures. The Company’s independent registered public accounting firm has not conducted an audit or review of, and does not express an opinion or any other form of assurance with respect to, the preliminary unaudited net operating loss for 2023. It is possible that the Company or its independent registered public accounting firm may identify items that require the Company to make adjustments to the preliminary estimates of net operating loss set forth herein and those changes could be material. Accordingly, undue reliance should not be placed on the preliminary estimates. The preliminary estimates are not necessarily indicative of any future period and should be read together with the sections of our filings with the Securities and Exchange Commission (the “SEC”) entitled “Risk Factors” and “Cautionary Statements Regarding Forward-Looking Statements”, and the Company’s financial statements, related notes and other financial information included in such filings.

The information in this Item 2.02 shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section or Sections 11 and 12(a)(2) of the Securities Act of 1933, as amended. The information contained in this Item 2.02 shall not be incorporated by reference into any filing with the SEC made by the Company, whether made before or after the date hereof, regardless of any general incorporation language in such filing.
