Amendment Description	This Amendment No. 1 on Form 8-K/A (this “Amendment”) amends the Current Report on Form 8-K (the “Original Report”), initially filed by Garmin Ltd. (the “Company”) with the Securities and Exchange Commission earlier today on April 30, 2025. Following the submission of the Original Report, the Company discovered that an incorrect item number was inadvertently tagged in the submission header (Item 2.02 should have been tagged instead of Item 2.01). This Amendment is being filed for the sole purpose of correcting the item tag in the submission header. No other modifications have been made to the Original Report, but for ease of reference, this Amendment restates in its entirety the Current Report, as amended.
