Basis of Presentation and Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements include the accounts of Garmin Ltd. and wholly-owned subsidiaries (collectively, the “Company” or “Garmin”). Intercompany balances and transactions have been eliminated.

The condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, the condensed consolidated financial statements reflect all adjustments, which are normal and recurring in nature, necessary for fair financial statement presentation. The condensed consolidated balance sheet at December 31, 2022 has been derived from the audited financial statements at that date, but does not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. Additionally, the condensed consolidated financial statements should be read in conjunction with Part I, Item 2, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of this Form 10-Q, and the Company’s Annual Report on Form 10-K for the year ended December 31, 2022.

Our operating results are subject to fluctuations associated with seasonal demand for consumer products, the timing of new product introductions, and OEM customer production schedules. Therefore, operating results for the 13-week period ended April 1, 2023 are not necessarily indicative of the results that may be expected for the year ending December 30, 2023.

The Company’s fiscal year is based on a 52- or 53-week period ending on the last Saturday of the calendar year. Therefore, the financial results of certain 53-week fiscal years, and the associated 14-week quarters, will not be exactly comparable to the prior and subsequent 52-week fiscal years and the associated 13-week quarters. The quarters ended April 1, 2023 and March 26, 2022 both contain operating results for 13 weeks.
