Liquidity and Management’s Plans The Company incurred a loss from operations, incurred a net loss, and used cash in operating activities for the three and nine months ended September 30, 2017. The Company has also suffered recurring losses from operations during the three years ended December 31, 2016.

The financial statements do not include any adjustments that might be necessary if the Company is unable to continue as a going concern. As discussed in Note 3, on April 18, 2017, the Company completed a private placement with several institutional and individual investors, and certain of its directors and officers, pursuant to which the Company generated gross proceeds of approximately $10.5 million, and net proceeds, after offering expenses of approximately $0.2 million, of approximately $10.3 million. The Company is using the proceeds from the private placement for working capital and general corporate purposes. In connection with the registration rights granted to these investors, the Company filed with the SEC a registration statement on Form S-3, which was declared effective on August 24, 2017. As discussed in Note 3, the Company has filed with the SEC an amended registration statement relating to a proposed public offering of non-transferable subscription rights to purchase shares of BIOLASE common stock. As of the date of the filing of the quarterly report on Form 10-Q of which these financial statements are a part, such registration statement has not yet become effective. If the proposed rights offering is consummated, the Company expects to receive gross proceeds of approximately $8.0 million to $12.0 million before expenses. As of September 30, 2017, the Company had working capital of approximately $14.7 million. The Company’s principal sources of liquidity as of September 30, 2017 consisted of approximately $4.7 million in cash and cash equivalents, and restricted cash and $9.7 million of accounts receivable. 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, the Company must increase sales of its products directly to end-users and through distributors, establish profitable operations through the combination of increased sales and decreased expenses, generate cash from operations or obtain additional funds when needed. The Company intends to improve its financial condition and ultimately improve its financial results by increasing revenues through expansion of its product offerings, continuing to expand and develop its 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 its advanced medical technologies, and reducing expenses. Additional capital requirements may depend on many factors, including, among other things, continued losses, the rate at which the Company’s business grows, 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, or enter into a line of credit facility. As discussed in Note 3, the Company has filed with the SEC an amended registration statement relating to a proposed public offering of non-transferable subscription rights to purchase shares of BIOLASE common stock. As of the date of the filing of this quarterly report on Form 10-Q, such registration statement has not yet become effective. If the proposed rights offering is consummated, the Company expects to receive gross proceeds of approximately $8.0 million to $12.0 million before expenses and to use such proceeds for the Company’s general working capital needs. The Company cannot provide assurance that it will be able to successfully consummate the rights offering, any other equity financing or any debt financing or enter into any line of credit facility in the future. The Company also cannot provide assurance that the required capital would be available on acceptable terms, if at all, or that any such financing activity would not be dilutive to our stockholders.
