Q: Who is entitled to vote?

A: Only holders of record of our common stock at the close of business on September 4, 2025 will be entitled to notice of, and to vote at, the Special Meeting. As of the close of business on the record date, 20,252,314 shares of common stock were issued and outstanding. Every shareholder is entitled to one vote for each share of common stock held on the record date.

●

Registered Shareholders. If our shares of common stock are registered directly in your name with our transfer agent, Continental Stock Transfer and Trust Company, you are considered the shareholder of record with respect to those shares, and the Notice or a printed set of the proxy materials was provided to you directly by us. As the stockholder of record, you have the right to grant your proxy directly to the individuals listed on the proxy card or to virtually vote live during the Special Meeting. Throughout this Proxy Statement, we refer to these registered stockholders as “stockholders of record.”

●

Street Name Stockholders. If our shares of common stock are held on your behalf by a broker, bank or other nominee, you are considered to be the beneficial owner of shares that are held in “street name,” and the Notice or a printed set of the proxy materials was forwarded to you by your broker or nominee, who is considered the stockholder of record with respect to those shares. As the beneficial owner, you have the right to direct your broker, bank or other nominee as to how to vote your shares.

Q: How do I vote?

A: If you are a stockholder of record, there are four ways to vote:

●

by Internet at www.proxyvote.com, 24 hours a day, seven days a week, until 11:59 p.m. Eastern Time on October 5, 2025 (have your Notice or proxy card in hand when you visit the website);

●

by toll-free telephone at 1-800-690-6903, until 11:59 p.m. Eastern Time on October 5, 2025 (have your Notice or proxy card in hand when you call);

●

by completing the enclosed proxy card and returning it in the pre-addressed, postage paid envelope provided to you (if you received printed proxy materials); or

●

by attending the virtual meeting by visiting www.virtualshareholdermeeting.com/NVVE2025SM3, where you may vote and submit questions during the meeting. Please have your control number located on your proxy card or Notice in hand when you visit the website.

If you hold your shares in street name through a broker, bank or other nominee, you will receive instructions from your broker, bank or other nominee on how to vote your shares. Your broker, bank or other nominee will allow you to deliver your voting instructions over the Internet and may also permit you to vote by telephone. In addition, if you received a printed copy of this Proxy Statement, you may submit your voting instructions by completing, dating and signing the voting instruction form that was included with this Proxy Statement and promptly returning it in the pre-addressed, postage paid envelope provided to you.

Q: How may my brokerage firm vote my shares if I fail to provide timely directions?

A: Banks and brokers acting as nominees are permitted to use discretionary voting authority to vote proxies for proposals that are deemed “routine” by the New York Stock Exchange, which means that they can submit a proxy or cast a ballot on behalf of stockholders who do not provide a specific voting instruction. Brokers and banks are not permitted to use discretionary voting authority to vote proxies for proposals that are deemed “non-routine” by the New York Stock Exchange. The determination of which proposals are deemed “routine” versus “non-routine” may not be made by the New York Stock Exchange until after the date on which this Proxy Statement has been mailed to you. As such, it is important that you provide voting instructions to your bank, broker or other nominee, if you wish to ensure that your shares are present and voted at the Special Meeting on all matters and if you wish to direct the voting of your shares on “routine” matters.

When there is at least one “routine” matter to be considered at a meeting, a broker “non-vote” occurs when a proposal is deemed “non-routine” and a nominee holding shares for a beneficial owner does not have discretionary voting authority with respect to the “non-routine” matter being considered and has not received instructions from the beneficial owner.

The approval of Proposal 1 (the Reverse Stock Split Proposal) and Proposal 2 (the Adjournment Proposal) are generally not considered to be “routine” matters and banks or brokers are not permitted to vote on these matters if the bank or broker has not received instructions from the beneficial owner.

Accordingly, it is particularly important that beneficial owners instruct their brokers how they wish to vote their shares for the Reverse Stock Split Proposal and the Adjournment Proposal. If such proposals are deemed to be “routine,” a bank or broker may be able to vote on the Reverse Stock Split Proposal and the Adjournment Proposal even if it does not receive instructions from you, so long as it holds your shares in its name.

Q: How will voting on any other business be conducted?

A: We are not aware of any business to be brought before the stockholders at the Special Meeting other than as described in this Proxy Statement. However, if any other business is properly presented for stockholder consideration, your signed proxy card gives authority to Gregory Poilasne and David Robson to vote on those matters in their discretion.

Q: What constitutes a quorum?

A: Stockholders may not take action during the Special Meeting unless there is a quorum present at the meeting. A meeting of stockholders is duly constituted, and a quorum is present, if, at the commencement of the meeting, there are present in person or by proxy holders representing one-third of the common stock outstanding and entitled to vote at the meeting. Abstentions, withheld and broker non-votes (as described above) will be included in the calculation of the number of shares considered to be present at the meeting for quorum purposes.

Q: How many votes are needed for approval of each proposal presented in this Proxy Statement?

A: Assuming a quorum is present at the Special Meeting:

●

Proposal 1 (the Reverse Stock Split Proposal): The affirmative vote of a majority of the votes cast by all stockholders present in person or represented by proxy at the Special Meeting and entitled to vote on the proposal is required to approve the Issuance Proposal. Shares that are not represented at the Special Meeting, abstentions, if any, and, if this proposal is deemed to be “non-routine,” broker non-votes, if any, with respect to this proposal will not affect the outcome of the vote on this proposal. If this proposal is deemed to be “routine,” no broker non-votes will occur on this proposal.

●

Proposal 2 (Adjournment Proposal): The affirmative vote of a majority of the votes cast by all stockholders present in person or represented by proxy at the Special Meeting and entitled to vote on the proposal is required to approve the Adjournment Proposal. Shares that are not represented at the Special Meeting, abstentions, if any, and, if this proposal is deemed to be “non-routine,” broker non-votes, if any, with respect to this proposal will not affect the outcome of the vote on this proposal. If this proposal is deemed to be “routine,” no broker non-votes will occur on this proposal.

Under the General Corporation Law of the State of Delaware, holders of the Common Stock will not have any dissenters’ rights or appraisal in connection with any of the matters to be voted on at the Special Meeting.

Q: Can I change my vote?

A: Yes. If you are a stockholder of record, you can change your vote or revoke your proxy by:

●

entering a new vote by Internet or by telephone until 11:59 p.m. Eastern Time on October 5, 2025;

●

completing and returning a later-dated proxy card at any time before the Special Meeting; and

●

by virtually attending and voting at the Special Meeting.

If you are a street name stockholder, your broker, bank or other nominee can provide you with instructions on how to change your vote.

Q: How are my shares voted if I submit a proxy but do not specify how I want to vote?

A: If you are a stockholder of record and you submit a properly executed proxy card or complete the telephone or Internet voting procedures but do not specify how you want to vote, your shares will be voted: (1) “FOR” the Reverse Stock Split Proposal; (2) “FOR” the Adjournment Proposal; and (3) in the discretion of the persons named as proxies on all other matters that may be brought before the Special Meeting.

Q: Who will count the vote?

A: The Company has appointed an inspector of elections for the meeting to count the votes.

Q: Who will pay for this proxy solicitation?

A: We will pay all the costs of soliciting these proxies, except for costs associated with individual stockholder use of the Internet and telephone. In addition to mailing proxy solicitation material, our directors and employees may solicit proxies in person, by telephone or by other electronic means of communication. We will also reimburse brokerage houses and other custodians, nominees and fiduciaries for their reasonable out-of-pocket expenses for forwarding proxy and solicitation materials to our stockholders. We have engaged Campaign Management as our proxy solicitor, and we estimate that we will pay Campaign Management a fee not to exceed $10,000, plus reimbursement for out of pocket expenses, to solicit proxies, though the costs of this proxy solicitation process could be lower or higher than our estimate.

Q: Where can I find the voting results of the Special Meeting?

A: We will announce preliminary voting results at the Special Meeting. We will also disclose voting results on a current report on Form 8-K that we will file with the SEC within four business days after the Special Meeting. If final voting results are not available to us in time to file a current report on Form 8-K within four business days after the Special Meeting, we will file a current report on Form 8-K to publish preliminary results and will provide the final results in an amendment to the current report on Form 8-K as soon as they become available.

Q: I share an address with another stockholder, and we received only one paper copy of the proxy materials. How may I obtain an additional copy of the proxy materials?

A: We have adopted a procedure called “householding,” which the SEC has approved. Under this procedure, we deliver a single copy of the Notice and, if applicable, our proxy materials to multiple stockholders who share the same address, unless we have received contrary instructions from one or more of such stockholders. This procedure reduces our printing costs, mailing costs and fees. Stockholders who participate in householding will continue to be able to access and receive separate proxy cards. Upon written or oral request, we will deliver promptly a separate copy of the Notice and, if applicable, our proxy materials to any stockholder at a shared address to which we delivered a single copy of any of these materials. To receive a separate copy, or, if a stockholder is receiving multiple copies, to request that we only send a single copy of the Notice and, if applicable, our proxy materials, such stockholder may contact via e-mail at sendmaterial@proxyvote.com.

Street name stockholders may contact their broker, bank or other nominee to request information about householding.

PROPOSAL 1

AMENDMENT TO THE COMPANY’S CERTIFICATE OF INCORPORATION AND

AUTHORIZATION OF THE BOARD TO EFFECT A REVERSE STOCK SPLIT

On September 3, 2025, the Board adopted a resolution approving, and recommending that the Company’s stockholders approve, this proposal to grant the Board the authority to file an amendment (the “Reverse Split Amendment”) to the Company’s Amended and Restated Certificate of Incorporation (the “Certificate”), to effect a reverse stock split (the “Reverse Stock Split”) at any ratio at the Board’s discretion, from 1-for-2 to 1-for-40, in order to comply with the Nasdaq minimum bid price requirements. Pursuant to the proposed Reverse Split Amendment, the form of which is attached to this proxy statement as Annex A.

Purposes and Effect of the Reverse Split Amendment

The Board has determined that it is in the best interests of the Company and its stockholders to implement the Reverse Stock Split in order to reduce the number of shares of Common Stock outstanding. The Board believes that approval of a proposal providing the Board with this generalized grant of authority with respect to setting the split ratio, rather than mere approval of a pre-defined reverse stock split, will give the Board flexibility to set the ratio in accordance with current market conditions and therefore allow the Board to act in the best interests of the Company and our stockholders. The Board intends to implement the Reverse Stock Split as soon as practicable if approved at the Special Meeting. The Reverse Stock Split proposal is not part of a going-private transaction.

The Reverse Stock Split is intended to provide the capital structure that may facilitate further potential business and financing transactions and also increase the trading price of the Company’s Common Stock and provide us with greater liquidity and a stronger investor base.

Our Common Stock is listed on the Nasdaq Capital Market. On August 27, 2023, we received a notification letter (the “Nasdaq Notification”) from the Listing Qualifications Department of The Nasdaq Stock Market LLC (“Nasdaq”) indicating that we failed to comply with the minimum bid price requirement for continued listing set forth in Nasdaq Listing Rule 5550(a)(2). Nasdaq Listing Rule 5550(a)(2) requires listed securities to maintain a minimum bid price of $1.00 per share, and Nasdaq Listing Rule 5810(c)(3)(A) provides that a failure to meet the minimum bid price requirement exists if the deficiency continues for a period of 30 consecutive business days. Normally, Nasdaq Notification would have provided that we had 180 calendar days from the date of the notification, or until February 23, 2026, to regain compliance. However, as indicated in the Nasdaq Notification, and pursuant to Listing Rule 5810(c)(3)(A)(iv), we not eligible for any compliance period specified in Rule 5810(c)(3)(A) due to the fact that we have effected a reverse stock split over the prior one-year period and has effected one or more reverse stock splits over the prior two-year period with a cumulative ratio of 250 shares or more to one. We have formally appealed the delisting determination set forth in the Nasdaq Notification, and we will be going before the Nasdaq Hearings Panel (the “Panel”) to defend our appeal in the near future.

If at any time before after the proposed Special Meeting, and the proposed reversed split is effected, and the closing bid price of our Common Stock is at or above $1.00 per share for a minimum of 10 consecutive business days, Nasdaq will provide the Company written confirmation of compliance. The Nasdaq staff may, in its discretion, require the Company to maintain a bid price of at least $1.00 per share for a period in excess of 10 consecutive business days, but generally no more than 20 consecutive business days, before determining that the Company has demonstrated an ability to maintain long-term compliance. If we implement the Reverse Stock Split, we must complete the split no later than 10 business days prior to the date set by Nasdaq Hearing Panel. If compliance cannot be demonstrated by the set date, Nasdaq will provide written notification that our securities will be delisted.

The Reverse Stock Split would decrease the total number of shares of our Common Stock outstanding and should, absent other factors, proportionately increase the market price of our Common Stock, which would be above $1.00 per share. Therefore, the Board believes that the Reverse Stock Split is an effective means for us to regain compliance with Nasdaq’s minimum bid price requirement.

After the Reverse Stock Split is effected, if at all, we will continue to be subject to the periodic reporting requirements of the Exchange Act. By itself, the Reverse Stock Split will not have any impact on the market in which our common stock is traded; however, our common stock would be identified with a new CUSIP number following any Reverse Stock Split.

Certain Risks Associated with the Reverse Stock Split

The effect of the Reverse Stock Split upon the market price for our Common Stock cannot be accurately predicted, and the history of similar stock split combinations for companies in like circumstances is varied. In particular, while we expect that the Reverse Stock Split will result in an increase in the per share price of our Common Stock, there is no assurance that the price per share of our Common Stock after the Reverse Stock Split is implemented will be two, ten, fifteen, twenty, thirty or forty times, as applicable, the price per share of our Common Stock immediately prior to the Reverse Stock Split. Furthermore, there can be no assurance that the market price of our Common Stock immediately after the Reverse Stock Split will be maintained for any period of time. This will depend on many factors, including our performance, prospects and other factors that may be unrelated to the number of shares outstanding.

Even if an increased share price can be maintained, the Reverse Stock Split may not achieve the other desired results which have been outlined above. In particular, we cannot assure you that the Reverse Stock Split will increase our stock price and have the desired effect of maintaining compliance with the initial and continued listing requirements of Nasdaq or any other national securities exchange. Moreover, because some investors may view a reverse stock split negatively, there can be no assurance that the Reverse Split Amendment will not adversely impact the market price of our Common Stock or, alternatively, that the market price following the Reverse Stock Split will either exceed or remain in excess of the current market price.

In addition, although we believe the Reverse Stock Split may enhance the desirability of our Common Stock to certain potential investors, we cannot assure you that, if implemented, our Common Stock will be more attractive to institutional and other long-term investors or that the liquidity of our Common Stock will increase since there would be a reduced number of shares outstanding after the Reverse Stock Split.

Stockholders should recognize that if the Reverse Stock Split is effected, they will own a smaller number of shares than they currently own (a number equal to the number of shares owned immediately prior to the Reverse Stock Split divided by two, ten, fifteen, twenty, thirty, or forty, as applicable). Therefore, if the Reverse Stock Split is implemented, some stockholders may consequently own less than one hundred shares of our Common Stock. A purchase or sale of less than one hundred shares (an “odd lot” transaction) may result in incrementally higher trading costs through certain brokers, particularly “full service” brokers. Therefore, those stockholders who own less than one hundred shares following the Reverse Stock Split may be required to pay modestly higher transaction costs should they then determine to sell their shares in the Company.

However, the Board has determined that these negative factors are outweighed by the potential benefits.

Mechanics of the Reverse Stock Split

No Fractional Shares

Stockholders will not receive fractional shares of Common Stock in connection with the Reverse Stock Split. Instead, stockholders who would have been entitled to a fractional share will receive such additional fraction of a share of Common Stock as is necessary to increase the fractional share to which they were entitled to a full share.

Effect on Stock Options and Warrants

	●	The per share exercise price of any outstanding stock options would be increased proportionately, and the number of shares issuable under outstanding stock options and all other outstanding equity-based awards would be reduced proportionately;

	●	The number of shares of Common Stock authorized for future issuance under our stock incentive plans would not be impacted by the Reverse Split; and

	●	The exercise, exchange or conversion price of all other outstanding securities that are exercisable or exchangeable for or convertible into shares of our Common Stock would be proportionately adjusted and the number of shares of Common Stock issuable upon such exercise, exchange or conversion would be proportionately adjusted.

The table below provides examples of a Reverse Stock Split at various ratios between 1-for-2 and 1-for-40:

Shares Outstanding as of September 4, 2025	Reverse Stock Split Ratio	Shares Outstanding After Reverse Stock Split	Reduction in Shares Outstanding
20,252,314	1-for-2	10,126,157	10,126,157
20,252,314	1-for-10	2,025,232	18,227,082
20,252,314	1-for-15	1,350,155	18,902,159
20,252,314	1-for-20	1,012,616	19,239,698
20,252,314	1-for-30	675,078	19,577,236
20,252,314	1-for-40	506,308	19,746,006

The Reverse Stock Split will affect all holders of the Company’s Common Stock uniformly and will not change the proportionate equity interests of such stockholders, nor will the respective voting rights and other rights of holders of the Company’s Common Stock be altered, except for possible changes due to the treatment of fractional shares resulting from the Reverse Stock Split.

The Reverse Stock Split will not affect total stockholders’ equity on the Company’s balance sheet. As a result of the Reverse Stock Split, the stated capital component attributable to the Company’s Common Stock will be reduced to an amount equal to one-half to one-fortieth of its present amount, in accordance with the range selected by the Board, and the additional paid-in capital component will be increased by the amount by which the Common Stock is reduced. Amounts for earnings (loss) per share of Common Stock will be restated for the effects of the Reverse Stock Split and will be higher than the previously disclosed amounts because there will be fewer shares of the Common Stock outstanding.

Authorized Shares of Common Stock

Because the number of authorized shares of Common Stock will not be reduced proportionately, the Reverse Stock Split will increase the ability of the Board to issue authorized and unissued shares without further stockholder action. We currently do not have any plans, arrangements or understandings to issue any of the authorized but unissued shares that would become available as a result of the Reverse Stock Split. However, as we have previously disclosed in our filings with the SEC, the development of our business will require substantial additional capital, and continued operations depend on our ability to raise additional funding, which could occur through fundraising transactions that involve issuance of shares of Common Stock or securities convertible into or exercisable for Common Stock; depending on several factors including the number of shares that are issued or issuable in any such transaction, such shares could include authorized but unissued shares that would become available as a result of the Reverse Stock Split.

Appraisal Rights

Under Delaware General Corporation Law, stockholders will not be entitled to exercise appraisal rights in connection with the Reverse Stock Split, and the Company will not independently provide stockholders with any such right.

Interest of Certain Persons in Matters to be Acted Upon

No officer or director has any interest that differs from our stockholders with regard to the treatment of any securities of the Company that they own in the event that the Reverse Stock Split is effected.

Certain U.S. Federal Income Tax Consequences of the Reverse Stock Split

The following is a summary of certain U.S. federal income tax consequences of the Reverse Stock Split generally applicable to beneficial holders of shares of the Common Stock and does not purport to be a complete discussion of all possible tax consequences. This discussion does not address all U.S. federal income tax considerations that may be relevant to particular stockholders in light of their individual circumstances or to stockholders that are subject to special rules such as financial institutions, tax-exempt organizations, insurance companies, dealers in securities, holders subject to the alternative minimum tax, regulated investment companies or real estate investment trusts, partnerships (or other flow-through entities for U.S. federal income tax purposes and their partners or members), traders in securities that elect to use a mark-to-market method of accounting for their securities holdings, persons holding Common Stock as a position in a hedging transaction, straddle, conversion transaction or other risk reduction transaction; persons who acquire shares of Common Stock in connection with employment or other performance of services; persons who hold Common Stock as qualified small business stock within the meaning of Section 1202 of the Code, U.S. expatriates and foreign stockholders. The following summary is based on the provisions of the Internal Revenue Code (the “Code”), applicable Treasury Regulations thereunder, judicial decisions and current administrative rulings, as of the date hereof, all of which are subject to change, possibly on a retroactive basis. Tax consequences under state, local, foreign, and other laws are not addressed herein. Each stockholder should consult his, her or its own tax advisor as to the particular facts and circumstances that may be unique to such stockholder and also as to any estate, gift, state, local or foreign tax considerations arising out of the Reverse Stock Split.

We have not sought, and will not seek, an opinion of counsel or a ruling from the Internal Revenue Service (“IRS”) regarding the United States federal income tax consequences of the Reverse Stock Split and there can be no assurance the IRS will not challenge the statements and conclusions set forth in this discussion or that a court would not sustain any such challenge. EACH HOLDER OF COMMON STOCK SHOULD CONSULT SUCH HOLDER’S TAX ADVISOR WITH RESPECT TO THE PARTICULAR TAX CONSEQUENCES OF THE REVERSE STOCK SPLIT TO SUCH HOLDER.

The federal income tax consequences of the Reverse Stock Split to a stockholder may depend upon whether such stockholder receives solely a reduced number of shares of Common Stock in exchange for its old shares of Common Stock or whether such stockholder also receives an additional fraction of a share of Common Stock (a “Round-Up Fractional Share”) as is necessary to increase the fractional share the shareholder would have received to a full share.

The Company believes that the Reverse Stock Split should constitute a recapitalization pursuant to Section 368(a)(1)(E) of the Code.

Subject to the discussion below addressing the receipt by certain shareholders of a Round-Up Fractional Share, a stockholder should not recognize gain or loss for federal income tax purposes as a result the Reverse Stock Split. In the aggregate, such stockholder’s basis in the reduced number of shares of Common Stock (aside from any Round-Up Fractional Share) should equal the stockholder’s basis in its old shares of Common Stock and such stockholder’s holding period in the reduced number of shares should include its holding period in its old shares exchanged therefore.

The federal income tax treatment to stockholders who receive a Round-Up Fractional Share is unclear. The IRS may take the position that the receipt of an additional portion of a share results in a distribution, that it results in gain or that no income or gain is recognized. Any income or gain recognized should not exceed the excess of the fair market value of such full share over the fair market value of the fractional share to which such stockholder was otherwise entitled. Stockholders are urged to consult their own tax advisors as to the possible tax consequences of receiving a Round-Up Fractional Share in the Reverse Stock Split.

The Company should not recognize any gain or loss as a result of the Reverse Stock Split.

The above discussion is solely written in connection with the proposed Reverse Stock Split and is not intended or written to be used, and cannot be used by any person, for the purpose of avoiding U.S. federal tax penalties.

THE BOARD RECOMMENDS THAT THE STOCKHOLDERS VOTE “FOR” THE APPROVAL OF THE

REVERSE SPLIT AMENDMENT TO THE CERTIFICATE OF INCORPORATION AND

AUTHORIZATION OF THE BOARD TO EFFECT A REVERSE STOCK SPLIT.

PROPOSAL 2

THE ADJOURNMENT PROPOSAL

The Adjournment Proposal, if adopted, will allow us to adjourn the Special Meeting from time to time, to a later date or dates to permit further solicitation of proxies. The Adjournment Proposal will only be presented to our stockholders in the event that there are insufficient votes for, or otherwise in connection with, the approval of the Issuance Proposal, or establish a quorum for the Special Meeting.

In this proposal, we are asking our stockholders to authorize the holder of any proxy solicited by our Board to vote in favor of adjourning the Special Meeting and any later adjournments. If our stockholders approve the Adjournment Proposal, we could adjourn the Special Meeting, and any adjourned session of the Special Meeting, to use the additional time to solicit additional proxies in favor of the aforementioned proposals or establish a quorum.

Among other things, approval of the Adjournment Proposal could mean that, even if proxies representing a sufficient number of votes against any of the proposals have been received, we could adjourn the Special Meeting without a vote on such proposal and seek to convince the holders of those shares to change their votes to votes in favor of the approval of such proposal.

Required Vote; Board of Directors Recommendation

The approval of the Adjournment Proposal requires the affirmative vote of a majority of the issued and outstanding shares of Common Stock present or represented by proxy and entitled to vote at the Special Meeting. You may vote “For” or “Against” or “Abstain” from this proposal. Abstentions will have the same effect as votes against this proposal. Broker non-votes will have no effect on this proposal.

THE BOARD UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” APPROVAL OF THE ADJOURNMENT PROPOSAL.

Nuvve Holding Corp. (the “Corporation”), a corporation existing under and by virtue of General Corporation Law of the State of Delaware (the “DGCL”), hereby certifies as follows:
