As previously disclosed, Nuvve Holding Corp. (the “Company”) previously entered into a cooperation agreement (the “Cooperation Agreement”), a service agreement for engineering and managerial consulting services (the “Managerial Services Agreement”) and an aggregation service agreement for battery energy storage system (BESS) (the “Aggregation Service Agreement” and together with the Cooperation Agreement and the Managerial Services Agreement, the “Omnia Venture Agreements”), each dated as of March 6, 2026, and each by and among the Company, Oelion AB, a company organized under the laws of Sweden, and OMNIA Group Holdings AG, a company organized under the laws of Switzerland (“Omnia”).

On August 24, 2026, upon the achievement of a milestone under the Omnia Venture Agreements relating to the payment by Omnia to the Company of the initial consulting fee of $385,439.25, the Company issued to Omnia 14,737 shares (the “Milestone Shares”) of the Company’s Series B Convertible Preferred Stock (the “Series B Preferred Stock”). Each share of the Series B Preferred Stock has a par value of $0.0001 per share and a stated value equal to $1,000.
