Management Discussion

Gregory Poilasne, Chief Executive Officer of Nuvve, said, “We were disappointed with the slowdown of EV adoption in the school bus market and the decline in revenues in 2025. We previously announced that we have pivoted our business strategy towards stationary storage aggregation services, and have seen an increase in our pipeline and backlog for stationary battery projects which we anticipate will accelerate the scaling of our platform in North America, Europe and Japan.”

2025 Fourth Quarter Financial Review

Total revenue was $1.95 million for the three months ended December 31, 2025, compared to $1.79 million for the three months ended December 31, 2024. The increase in revenue was attributed to increase in products due to higher customers sales orders and shipments, and increase in grants revenue, partially offset by decrease in services revenue. Products and services revenue for the three months ended December 31, 2025 consisted of sales of DC and AC Chargers of about $1.39 million, grid services revenue of $0.01 million, and engineering services of $0.34 million, compared to sales of DC and AC $1.18 million, grid services of $0.01 million, and engineering services of $0.51 million for the three months ended December 31, 2024. The decrease in service revenue is due to the absence of management fees earned related to the Fresno EV infrastructure project. We stopped accruing management fees earned for the Fresno EV infrastructure project during the second quarter of 2025.

Cost of product and service revenues was $1.46 million for the three months ended December 31, 2025, compared to $1.50 million for the three months ended December 31, 2024, a 2.8% decrease. Products and services margins for the three months ended December 31, 2025 increased by 4.5% to 16.0%, compared to 11.5% for the same prior year period. Margin was positively impacted by a higher mix of hardware charging stations sales and a lower mix of engineering services.

During the fourth quarter of 2025, we determined that certain 125 kW V2G DC Chargers held in inventory and purchased from our former third party supplier were not conforming to our commercial product reliability standards and they would no longer be offered for sale domestically. Given the commercial reliability issues with those DC chargers, we recognized a total inventory impairment charge of $3.47 million, reducing the carrying value of those inventories to zero. The inventory impairment loss is presented as a separate line item in the consolidated statements of operations due to its significance.

Selling, general and administrative expenses consist of selling, marketing, payroll, administrative, finance, and professional expenses. Selling, general and administrative expenses were $3.0 million for the three months ended December 31, 2025, as compared to $5.1 million for the three months ended December 31, 2024, a decrease of $2.1 million, or 40.9%. The decrease during the three months ended December 31, 2025 was primarily attributable to decreases in compensation expenses of $1.7 million, including share-based compensation, decrease in public company related expenses of $0.6 million, decrease in travel-related expenses of $0.2 million, decrease in office related expenses of $0.2 million, decrease in information technology related expenses of $0.1 million, partially offset by increase in insurance related expenses of $0.4 million, and increase in legal expenses of $0.3 million.

Research and development expenses increased by $0.1 million, or 12.1%, from $0.8 million for the three months ended December 31, 2024 to $0.7 million for the three months ended December 31, 2025. The increases during the three months ended December 31, 2025 were primarily attributable to increases in compensation expenses and subcontractor expenses used to advance our platform functionality and integration with vehicles and stationary batteries.

Other income, net consists primarily of interest expense, change in fair value of convertible notes, change in fair value of warrants liability, sublease income and other income (expense). Other income (expense) was $0.38 million in other income for the three months ended December 31, 2025, compared to $0.52 million of other income for the three months ended December 31, 2024, a decrease of $0.14 million of income. The decrease during the three months ended December 31, 2025 was primarily attributable to the change in fair values of the convertible notes and warrants liability, partially offset by increases in sublease income related to the subleasing of part of our main office space, and interest expense on debt obligations.

Net loss was $6.3 million for the three months ended December 31, 2025, compared to $5.1 million for the three months ended December 31, 2024, an increase of $1.2 million or 23.7%. The increase in net loss was primarily due to a increase in operating expenses of $1.2 million, partially offset by decrease in other income, net of $0.1 million and increase in revenue of $0.16 million.

Net Loss Attributable to Non-Controlling Interest

Net loss attributable to non-controlling interest was $0.23 million and $0.03 million for the three months ended December 31, 2025 and 2024, respectively.

Net loss is allocated to non-controlling interests in proportion to the relative ownership interests of the holders of non-controlling interests in the entities.

Megawatts Under Management

Megawatts under management refers to the potential available charging capacity Nuvve is currently managing around the world.

Megawatts under management in the fourth quarter increased 7.2% over the third quarter of 2025, to 28.3 megawatts from 26.4 megawatts, and a 7.8% decrease compared to the fourth quarter of 2024. Stationary batteries we managed in California were decommissioned as they reached the end of their useful life. Our customer intends to replace these batteries in the future, and we are working with this customer to propose our battery aggregation services once their new batteries are installed. In Japan we elected to not continue the management of stationary batteries connected to our platform in partnership with Toyota Tsusho that we had managed for several years, given that expected future revenue generation was limited under our existing agreement. Instead we have focused our efforts in driving new business development efforts in Japan, with a focus on battery aggregation services for commercial and governmental customers throughout the country.
