We are subject to various claims, complaints and legal actions that arise from time to time in the normal course of business, including commercial insurance, product liability, intellectual property and employment related matters. In addition, from time to time we may bring claims or initiate lawsuits against various third parties with respect to matters arising out of the ordinary course of our business, including commercial and employment related matters.

Securities Class Actions

Between August 21 and October 9, 2024, three substantially similar putative class action complaints were filed against us and certain of our executive officers in the United States District Court for the Southern District of California. On December 13, 2024, the court appointed lead plaintiff court and consolidated the three actions (now captioned In re Dexcom, Inc. Class Action Securities Litigation, Lead Case No.: 24-cv-1485-RSH-VET). On January 27, 2025, lead plaintiff filed a consolidated complaint. The consolidated complaint alleges violations of the Exchange Act against us and certain of our current and former executive officers for allegedly making false and misleading statements between April 28, 2023 and July 25, 2024, with respect to our expected revenue for fiscal 2024 and ability to capitalize on our growth potential. On March 13, 2025, we filed a motion to dismiss the consolidated complaint. On May 14, 2025, the court granted the motion to dismiss with leave to amend. On May 28, 2025, lead plaintiff filed an amended consolidated complaint. On June 11, 2025, we filed a motion to dismiss the amended consolidated complaint. On October 7, 2025, defendants answered the amended consolidated complaint. On October 10, 2025, defendants filed a motion for judgment on the pleadings. The motion for judgment on the pleadings will be fully briefed on November 7, 2025.

On October 27, 2025, a putative class action complaint was filed against us and certain of our executive officers in the United States District Court for the Southern District of New York (captioned Prime v. Dexcom, Inc., et al, Case No.: 1:25-cv-08912). The complaint alleges violations of the Exchange Act against us and certain of our executive officers for allegedly making false and misleading statements between July 26, 2024 and September 17, 2025, with respect to the accuracy, reliability, and functionality of our G7 device, as well as our enhancements to and manufacturing of the device. Motions for lead plaintiff are due December 26, 2025.

Derivative Actions

Between September 13 and April 14, 2025, three putative stockholders filed derivative lawsuits against us and certain of our current and former executive officers and directors in the United States District Court for the Southern District of California. The derivative complaints allege factual allegations largely tracking allegations made in the In re Dexcom, Inc. Securities Class Action Litigation and seek, among other things, damages and restitution to be paid to the Company by the individual defendants, punitive damages, and attorney’s fees and costs. These actions have been consolidated (captioned In Re: Dexcom, Inc. Stockholder Derivative Litigation, Lead Case No.: 24-cv-1645-RSH-VET), and were stayed until September 9, 2025, when the court granted in part and denied in part the motion to dismiss in the In re Dexcom, Inc. Securities Class Action Litigation. On October 24, 2025, the parties filed a joint motion to set a schedule for the filing of an amended consolidated complaint and briefing of any motion to dismiss filed in response thereto.

On September 25, 2025, an additional derivative lawsuit was filed against us and certain of our current and former executive officers and directors in the Court of Chancery of the State of Delaware. The allegations largely track those made in the In re Dexcom, Inc. Securities Class Action Litigation and seek, among other things, damages and restitution to be paid to the Company by the individual defendants, punitive damages, and attorney’s fees and costs.

We intend to vigorously defend against such claims; however, we cannot be certain of the outcome of our ongoing proceedings and, if determined adversely to us, our business and financial condition may be adversely affected.

We do not believe we are party to any other currently pending legal proceedings, the outcome of which could have a material adverse effect on our business, financial condition, or results of operations. There can be no assurance that existing or future legal proceedings arising in the ordinary course of business or otherwise will not have a material adverse effect on our business, financial condition, or results of operations.
