Interim Financial Statements

The accompanying unaudited condensed consolidated financial statements of the Company as of  June 30, 2025 and  December 31, 2024 and for the three and six months ended June 30, 2025 and June 30, 2024, have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim information and with the instructions on Form 10-Q and Rule 10-01 of Regulation S-X pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). In accordance with those rules and regulations, the Company has omitted certain information and notes required by GAAP for annual consolidated financial statements. In the opinion of management, the condensed consolidated financial statements contain all adjustments, except as otherwise noted, necessary for the fair presentation of the Company’s financial position and results of operations for the periods presented. The year-end condensed balance sheet data was derived from audited financial statements. These condensed consolidated financial statements should be read in conjunction with the Consolidated Financial Statements and Notes thereto included in the Company’s Annual Report on Form 10-K ("Annual Report") for the fiscal year ended December 31, 2024. The results of operations for the three and six months ended June 30, 2025 are not necessarily indicative of the results expected for the entire fiscal year. All significant inter-company accounts and transactions have been eliminated.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported. Actual results could differ materially from those estimates in the consolidated financial statements and accompanying notes. Significant estimates and assumptions that impact these financial statements and the accompanying notes relate to, among other things, revenue recognition, allowance for credit losses, inventory reserve, impairment of long-lived assets, service and product warranty costs, share-based compensation expense, estimated useful lives of tangible and intangible assets, and taxes.

Product Warranty

The Company generally offers a one-year limited warranty for its products but it can extend for longer periods of three to five years for certain products sold to certain customers. The Company estimates the costs that  may be incurred under its basic limited warranty and records a liability for the amount of such costs at the time when product defects occur. Factors that affect the Company’s warranty liability include the historical and anticipated rates of warranty claims and cost to repair. While the Company believes that its warranty accrual is adequate, the actual warranty costs  may exceed the accrual, in which case the cost of sales will increase in the future. As of June, 30, 2025 and  December 31, 2024, the amount of accrued warranty was $0.36 million and $0.28 million, respectively.
