Item 8.01 Other Events.

On June 30, 2021, DexCom, Inc. (the "Company") initiated litigation against Abbott Diabetes Care, Inc. ("Abbott") for infringement of certain of the Company's patents (the "Litigation").

Abbott previously sued the Company for patent infringement in United States District Court for the District of Delaware on August 11, 2005 (the "Prior Litigation"). The parties settled the Prior Litigation on July 2, 2014 with a Settlement and License Agreement, which contained a covenant not to sue that expired on March 31, 2021. That covenant has not been extended by the parties. The Company is therefore taking steps to protect and enforce its intellectual property rights. The Litigation alleges that Abbott's Libre products infringe the Company's patents covering its proprietary continuous glucose monitoring technology. The Litigation seeks damages and injunctive relief.
