Senseonics Holdings, Inc.

From time to time, we are subject to litigation and claims arising in the ordinary course of business. Although the results of litigation and claims cannot be predicted with certainty, we currently believe that the final outcome of these ordinary course matters will not have a material adverse effect on our business. Legal proceedings, including litigation, government investigations and enforcement actions could result in material costs, occupy significant management resources and entail civil and criminal penalties.

In May 2024, the Company received notice and accepted service of a civil complaint that had been filed in the Eastern District of Texas and styled Cellspin Soft, Inc. vs. Senseonics Holdings, Inc., and Ascensia Diabetes Care Holdings AG Case No. 2:24-cv 263. The case was filed by a non-practicing entity alleging patent infringement of three patents. The validity of all three of these patents were challenged in Inter Partes Review proceedings at the U.S. Patent and Trademark Office by another party, TikTok Inc., (the “TikTok IPR”) and on September 30, 2024, the Patent Trial and Appeal Board instituted a review with respect to each of the asserted claims in these three patents. Together with LifeScan, Inc. and Ascensia, on October 30, 2024, we filed a joint motion to join the TikTok IPR as well as our own joint independent, similar Inter Partes Review (the “Senseonics IPR”) petitions challenging these patents. On February 5, 2025, the court issued an order staying the proceedings in the Eastern District of Texas pending resolution of the Inter Partes Reviews. On June 5, 2025, prior to the imminent TikTok IPR final hearings, the Acting Director of the U.S. Patent and Trademark Office ordered a sua sponte review by the Acting Director of whether the TikTok IPR could proceed based on certain novel issues relating to TikTok’s Chinese ownership status. On January 23, 2026, the Director of the U.S. Patent and Trademark Office issued and order stating that, in view of a recent order by the Patent Trial and Appeal Board and TikTok Inc.’s announced Joint Venture (and the referenced ownership attributes thereof), the parties were authorized to file an additional brief addressing whether the evidence Cellspin Soft, Inc. submitted is sufficient to put TikTok Inc.’s real party in interest identification into dispute, and what effect, if any, the announced Joint Venture has on the TikTok IPR proceedings. TikTok, Inc. and Cellspin Soft, Inc. filed additional briefs on February 2, 2026. On March 30, 2026, the Director of the U.S. Patent and Trademark Office issued an order vacating the Board’s decisions granting institution of the TikTok IPR and denied the TikTok IPR petitions. The Director also vacated the Board’s order joining the Senseonics IPR to the TikTok IPR, and ordered the Board to determine whether the Senseonics IPR should be instituted on their own. On April 15, 2026, the Board granted institution of the Senseonics IPR on all three patents involved in the district court litigation. The Board further ordered that a final hearing will be held on June 30, 2026 on the Senseonics IPR. On April 20, 2026, Cellspin requested rehearing of the Board’s April 15, 2026 institution decisions. On April 28, 2026, the Board denied Cellspin’s requests for rehearing. Should any asserted claim in the three patents survive the invalidity challenge in the Senseonics Inter Partes Review proceedings, the Company intends to vigorously defend the lawsuit. The proceedings in the Eastern District of Texas remain stayed pending resolution of the Senseonics IPR.

Except as described above, we are not currently a party to any material legal proceedings, and we are not aware of any pending or threatened legal proceeding against us that we believe could have a material adverse effect on our business, operating results or financial condition.
