Our ticker symbol on The Nasdaq Stock Market LLC is “DORM.” The accompanying unaudited condensed consolidated financial statements have been prepared under U.S. generally accepted accounting principles (“GAAP”) for interim financial information and under the rules and regulations of the U.S. Securities and Exchange Commission. However, they do not include all the information and footnotes required by GAAP for a complete set of financial statements. In the opinion of management, all adjustments (comprising only normal, recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 27, 2025, are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2025, or any future period. We may experience significant fluctuations from quarter to quarter in our results of operations due to the timing of orders placed by our customers and the introduction of new products and product lines to customers. These financial statements should be read in conjunction with the consolidated financial statements and footnotes thereto included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.
