Nuvve Holding Corp. ("Nuvve" or the "Company") (NASDAQ:NVVE), a global leader in grid modernization, vehicle-to-grid (V2G) technology and grid-interactive energy solutions, today announced that it plans to effect a 1-for-18 reverse stock split of its common stock, that is expected to become effective as of 12:01 a.m. Eastern Time on Monday, July 6, 2026. Nuvve’s common stock is expected to begin trading on a split-adjusted basis commencing upon the market open on Monday, July 6, 2026.

Following the reverse stock split, the Company’s common stock will continue to trade on The Nasdaq Capital Market under the symbol "NVVE" with the new CUSIP number, 67079Y506.

At the effective time of the reverse stock split, every 18 shares of Nuvve’s issued and outstanding common stock will be automatically converted into one issued and outstanding share of common stock without any change in the par value of $0.0001 per share. The reverse stock split will reduce the number of issued and outstanding shares of the Company’s common stock from approximately 9,443,731 shares to approximately 524,652 shares, subject to adjustment for fractional shares. The total authorized number of shares will not be reduced. Proportional adjustments will be made to the number of shares of common stock issuable upon exercise or vesting of the Company’s outstanding stock options, restricted stock units, and warrants, as well as the applicable exercise or conversion prices, and to the number of shares issuable under the Company’s equity incentive plans and other existing agreements. No fractional shares will be issued in connection with the reverse stock split, and fractional shares resulting from the reverse stock split will be rounded up to the nearest whole share. With respect to outstanding common stock held in "street name" through a bank, broker or other nominee, fractional shares will be rounded up at the participant level. Cash will not be paid for fractional shares.

At the Company’s special meeting of stockholders held on June 23, 2026, the Company approved, among other things, a proposal granting the Company’s Board of Directors the discretion to amend the Company’s certificate of incorporation to effect a reverse stock split of the Company’s common stock at a ratio of not less than 1-for-2 and not more than 1-for-18. Following the special meeting of stockholders, on June 23, 2026, the Company’s Board of Directors approved a 1-for-18 reverse stock split ratio. The reverse stock split is being implemented with the goal of bringing the Company into compliance with the minimum bid price requirement of $1.00 per share of common stock for continued listing on the Nasdaq Capital Market.

Nuvve’s transfer agent, Continental Stock Transfer & Trust Company, will provide information to stockholders regarding their stock ownership following the reverse stock split. Stockholders holding their shares in book-entry form or through a bank, broker or other nominee do not need to take any action in connection with the reverse stock split. Their accounts will be automatically adjusted to reflect the number of shares owned. Beneficial holders are encouraged to contact their bank, broker or other nominee with any procedural questions.
