| Description of contract termination and claims | Pixium indicated that it considered this termination wrongful, rejected the Company’s offers, but retained the $1,000,000 payment. On May 19, 2021, Pixium filed suit in the Paris Commercial Court, and currently claims damages of approximately €5.1 million or about $5.6 million. The Company believes it has fulfilled its obligations to Pixium with the liquidated damages payment of $1,000,000. | |||||||||||

| Description of legal settlement | On December 8, 2022, the Company received notice that the Paris Commercial Court had rendered its judgment, including finding that the Company’s termination of the MOU was not valid. In the judgment, the Company was ordered to pay to Pixium the amount of €2,500,000 minus a €947,780 credit for the $1,000,000 already paid, a net amount payable of approximately €1,552,220. We recorded a charge of $1,675,000 for the year ended December 31, 2022, related to this matter but plan to continue our appeal against the preliminary judgment. On May 24, 2023, the Company filed an appeal against the judgment from the Paris Commercial Court except in so far as such prior judgment dismissed (i) Pixium’s claim for the Company to pay it a sum of €480,693 relating to the alleged time spent by its teams, (ii) Pixium’s application to order the Company to pay it a sum of €1,500,000 in respect to alleged loss of opportunity and (iii) deducted the sum of $1,000,000 that the Company already paid Pixium and which Pixium retained converted into euros at the date of the judgment. Thereafter Pixium filed its brief with Paris Court of Appeal and filed a cross-appeal on January 18, 2024. Meanwhile, the Company received notice that the Paris Commercial Court had opened safeguard proceedings against Pixium by judgment dated October 9, 2023, then in its judgment dated November 13, 2023, converted safeguard proceedings into receivership, and in its judgment dated January 31, 2024, converted Pixium’s receivership proceedings to liquidation proceedings, the transfer plan being rejected. As a result, Pixium’s liquidator intervened on behalf of Pixium in the pending proceedings before the Paris Court of Appeal and filed its brief on March 21, 2024. The Company filed its brief in reply with the Paris Court of Appeal on April 17, 2024. Proceedings before the Paris Court of Appeal are pending. In parallel, because the Company has failed to enforce the judgment, Pixium requested the pre-trial judge to strike out the Company's appeal for failure to enforce the judgment. The hearing took place on June 4, 2024 and on October 23, 2024, the pre-trial judge issued his order, striking out Vivani's appeal for failure to enforce the decision. As of September 30, 2026, the Company adjusted the litigation accrual to $1.79 million to reflect the amount paid on October 1, 2026, with the resulting foreign currency adjustment recognized within other income, net in the condensed consolidated statements of operations. On October 1, 2026, the Company paid the remaining balance of $1,790,000 to reinstate the case on the court's docket and prevent the appeal proceeding from lapsing. On November 2, 2026, the correspondent before the Paris Court of Appeal confirmed that the Conseiller de la mise en état had reinstated the appeal, and that the case will now proceed on the merits, as no objection was raised by the liquidator. | |||||||||||
