enVVeno Medical (NASDAQ: NVNO) adds reverse stock split vote to 2025 meeting

Rhea-AI Filing Summary

enVVeno Medical Corporation is asking stockholders to approve authority for a reverse stock split of its common stock, at a ratio between one-for-five and one-for-thirty-five, to be implemented at the Board’s discretion if approved. The company currently has 20,216,176 shares outstanding; for example, at a one-for-five ratio this would become approximately 4,043,235 shares. The Board states its main goal is to lift the share price above Nasdaq’s $1.00 minimum bid requirement after receiving notice that the stock traded below that level for 30 consecutive business days, with a recent closing price of $0.3297 per share. The reverse split would not change authorized share counts, so it would increase the pool of authorized but unissued shares, and each holder’s ownership percentage is expected to remain about the same aside from fractional-share cashouts. The Board also reduced the quorum requirement for stockholder meetings to thirty three and one-third percent of voting shares outstanding.

Equity & Corporate Actions Analyst

enVVeno seeks flexible reverse split authority to address Nasdaq bid-price deficiency.

enVVeno Medical is adding a fifth proposal to its 2025 annual meeting agenda to authorize a reverse stock split in a wide range from one-for-five to one-for-thirty-five. The Board ties this directly to Nasdaq rules, noting the stock closed at $0.3297 on November 18, 2025 and that Nasdaq has notified the company it no longer meets the $1.00 minimum bid requirement. The split would be effected, if at all, via a certificate of amendment filed at the Board’s sole discretion.

The reverse split would not change the number of authorized common or preferred shares, but would reduce outstanding shares from 20,216,176 to, for example, about 4,043,235 at one-for-five or 577,605 at one-for-thirty-five. That structure preserves each holder’s proportional ownership, aside from cash in lieu of fractional shares, while increasing the number of authorized but unissued shares. The company states the move is not part of a plan to go private and that the Board can abandon the split even if it receives approval.

The filing also discloses that the Board amended bylaws on November 17, 2025 to lower the quorum requirement from a majority to thirty three and one-third percent of outstanding voting shares. Approval of the reverse split proposal requires a majority in voting power of shares present in person or by proxy and entitled to vote, and it is classified as a routine matter, allowing brokers to vote without specific instructions if none are provided.

QUESTIONS AND ANSWERS ABOUT THESE SUPPLEMENTAL PROXY MATERIALS

Important Note: These supplemental materials supplement the Proxy Statement for the 2025 Annual Meeting of Stockholders as originally filed with the SEC and made available to our stockholders on or about October 31, 2025. For more information regarding the Meeting, including questions and answers regarding the Meeting and a detailed description of Proposals 1 through 4, please refer to the Proxy Statement.

Why am I receiving this Supplement?

This Supplement describes new Proposal 5 which is being added to the agenda for the Meeting and therefore were not described in the original Proxy Statement. Information about Proposals 1 through 4, each of which will also be presented to stockholders at the Meeting, can be found in the Proxy Statement as originally filed with the SEC and made available to our stockholders on or about October 31, 2025.

New Proposal 5 seeks stockholder approval to grant authority to the Company’s Board of Directors to effectuate a reverse stock split of the Company’s common stock at a ratio of between one-for-five and one-for-thirty-five, with such ratio to be determined at the sole discretion of the Board of Directors and with such reverse stock split to be effectuated at such time and date, if at all, as determined by the Board of Directors in its sole discretion.

To the extent the information in the Supplement differs from, updates or conflicts with the information contained in the Proxy Statement, the information in the Supplement shall amend and supersede the information contained in the Proxy Statement. Except as so amended or superseded, all information set forth in the Proxy Statement remains unchanged and important for you to review. Accordingly, we urge you to read the Supplement carefully in its entirety together with the Proxy Statement. All capitalized terms used in the Supplement and not otherwise defined herein have the respective meanings given to them in the Proxy Statement. The Supplement is being made available to our stockholders on or about November 21, 2025.

How will the Supplement and proxy materials be delivered?

Most of our stockholders who are entitled to notice of, and to vote at, the Meeting previously received a Notice of Internet Availability of Proxy Materials for the Meeting, which provided instructions on how to access the proxy materials on the Internet, but did not receive printed copies of the proxy materials unless they requested them. We will provide access to the Supplement, the Amended Notice of Annual Meeting and a proxy card reflecting all five proposals to be voted on at the Meeting, both by mailing to you a full set of these supplemental materials, and also by notifying you of the availability on the Internet of all of our proxy materials, including these supplemental materials and the Proxy Statement and our annual report for the year ended December 31, 2024.

How many shares must be present or represented to conduct business at the Meeting?

On November 17, 2025, the Board amended the Company’s amended and restated bylaws to reduce the quorum requirement for a meeting of stockholders from a majority of the outstanding shares of our voting stock entitled to vote at a meeting to thirty three and one-third percent of the outstanding shares of our voting stock entitled to vote at a meeting. Accordingly, a quorum will be present if at least thirty three and one-third percent of the outstanding shares of our voting stock entitled to vote is represented at the Meeting, either virtually or by proxy.

How may I vote with respect to the reverse stock split proposal and how are votes counted?

With respect to Proposal 5, you may vote “for” or “against” the proposal or you may “abstain” from casting a vote on such proposal. Abstentions and broker non-votes will be counted for the purpose of determining whether a quorum is present at the Meeting.

Broker non-votes occur on a matter when a broker is not permitted to vote on that matter without instructions from the beneficial owner and instructions are not given. These matters are referred to as “non-routine” matters. Proposals 1, 2 and 4 are “non-routine.” Thus, in tabulating the voting result for these proposals, shares that constitute broker non-votes are not considered votes cast on those proposals. The ratification of the appointment of the Company’s independent public accountant and the reverse stock split proposal are “routine” matters and therefore a broker may vote on this matter without instructions from the beneficial owner as long as instructions are not given.

4

How many votes are required to approve the reverse stock split proposal?

The affirmative vote of the holders of a majority in voting power of the shares of stock of the corporation which are present in person or by proxy and entitled to vote thereon is required to grant authority to the Company’s Board of Directors to effectuate a reverse stock split of the Company’s common stock at a ratio of between one-for-five and one-for-thirty-five, with such ratio to be determined at the sole discretion of the Board of Directors and with such reverse stock split to be effectuated at such time and date, if at all, as determined by the Board of Directors in its sole discretion. Abstentions will have the effect of a vote against this proposal, but since this is a routine matter, brokers may vote at the Meeting on this proposal provided that they have not received instructions from a beneficial owner.

How do I cast or revoke my proxy for the reverse split proposal?

Because this Supplement describes a new proposal to be voted on at the Meeting that was not reflected or described in the original Proxy Statement, proxies submitted before the date of the Supplement will not include votes on the new proposal. As a result, if you want to vote on the new proposal described in the Supplement, you must cast a new vote for the Meeting by signing, dating and returning the enclosed proxy card (or by following the instructions to vote by Internet or telephone), or by voting at the Meeting.

Signing and submitting the new proxy card, or voting at the Meeting, will revoke any prior proxy in its entirety. Therefore, if you submit the new proxy card (or vote by Internet or telephone), in addition to voting on Proposal 5, you must mark the new proxy card in the appropriate place (or follow the instructions to vote by Internet or telephone) to indicate your vote on Proposals 1 through 4.

PROPOSAL NO. 5: THE REVERSE SPLIT PROPOSAL

Introduction

Our Board acted unanimously to adopt a proposal to grant authority to the Board to effectuate a reverse stock split of the Company’s common stock at a ratio of between one-for-five and one-for-thirty-five (the “Reverse Split”), with such ratio to be determined at the sole discretion of the Board and with such reverse stock split to be effectuated at such time and date, if at all, as determined by the Board of Directors in its sole discretion (the “Reverse Split Proposal”). The Board is now asking you to approve this Reverse Split Proposal.

If approved, the Reverse Split will be effective upon the filing of a certificate of amendment to our Amended and Restated Certificate of Incorporation, in substantially the form attached to this Supplement as Annex A (the “Certificate of Amendment”), with the Secretary of State of Delaware, with such filing to occur, if at all, at the sole discretion of the Board.

The intention of the Board in obtaining approval for the authority to effect a Reverse Split would be to increase the stock price of our common stock sufficiently above the $1.00 minimum bid price requirement for continued listing on The Nasdaq Capital Market (“Nasdaq”) if necessary in the future. Additionally, we received notice from The NASDAQ Stock Market indicating that, because the closing bid price for the Company’s common stock had fallen below $1.00 per share for 30 consecutive business days, the Company no longer complies with the minimum bid price requirement for continued listing on the Nasdaq Capital Market under Rule 5550(a)(2) of Nasdaq Listing Rules. Nasdaq’s notice has no immediate effect on the listing of the Company’s common stock on the Nasdaq Capital Market. If we are unable to resolve the situation to allow for continued listing on the Nasdaq Capital Market, this will result in a de-listing of our common stock.

The Reverse Split will not impact our authorized shares of common stock. Accordingly, the effect of the Reverse split will be to increase the number of authorized but unissued shares of common stock of the Company. The Board, in its sole discretion, can elect to abandon the Reverse Split in its entirety at any time.

One principal effect of the Reverse Split would be to decrease the number of outstanding shares of our common stock. Except for de minimus adjustments that may result from the treatment of fractional shares as described below, the Reverse Split will not have any dilutive effect on our stockholders since each stockholder would hold the same percentage of our common stock (in hand or on an as converted basis) outstanding immediately following the Reverse Split as such stockholder held immediately prior to the Reverse Split. The relative voting and other rights that accompany the shares would not otherwise be affected by the Reverse Split. The authorized number of shares of common stock and preferred stock will not be adjusted as a result of the Reverse Split.

The table below sets forth the number of shares of our common stock outstanding before and approximate number of shares outstanding after the Reverse Split based on 20,216,176 shares of our common stock outstanding as of the Record Date.

			Prior to the Reverse Split			Assuming a One- for- Five Reverse Split			Assuming a One- for- Ten Reverse Split			Assuming a One- for- Twenty Reverse Split			Assuming a One- for- Thirty Reverse Split			Assuming a One- for- Thirty-Five Reverse Split
Aggregate Number of Shares of common stock Outstanding			20,216,176			4,043,235			2,021,617			1,010,808			673,872			577,605

The Reverse Split is not part of a broader plan to take us private.

Reasons for the Reverse Split; Nasdaq Requirements for Continued Listing

The Board’s primary objective in proposing a potential Reverse Split is to raise the per share trading price of our common stock. Our common stock currently trades on Nasdaq under the symbol “NVNO.” In order to maintain our listing on Nasdaq we may be required to effect the Reverse Split so that our listed shares maintain a minimum bid price per share of at least $1.00. The closing trading price on November 18, 2025 was $0.3297.

6

Our Board concluded that the liquidity and marketability of our common stock will be adversely affected if it is not listed on a national securities exchange as investors can find it more difficult to dispose of, or to obtain accurate quotations as to the market value of, our common stock. Our Board believes that current and prospective investors will view an investment in our common stock more favorably if our common stock remains listed on Nasdaq.

Our Board also believes that the Reverse Split and any resulting increase in the per share price of our common stock will enhance the acceptability and marketability of our common stock to the financial community and investing public. Many institutional investors have policies prohibiting them from holding lower-priced stocks in their portfolios, which reduces the number of potential buyers of our common stock, although we have not been told by them that is the reason for not investing in our common stock. Additionally, analysts at many brokerage firms are reluctant to recommend lower-priced stocks to their clients or monitor the activity of lower-priced stocks. Brokerage houses frequently have internal practices and policies that discourage individual brokers from dealing in lower-priced stocks. Further, because brokers’ commissions on lower-priced stock generally represent a higher percentage of the stock price than commissions on higher priced stock, investors in lower-priced stocks pay transaction costs which are a higher percentage of their total share value, which may limit the willingness of individual investors and institutions to purchase our common stock.

We cannot assure you that the Reverse Split will have any of the desired effects described above. More specifically, we cannot assure you that after the Reverse Split the market price of our common stock will increase proportionately to reflect the ratio for the Reverse Split, that the market price of our common stock will not decrease to its pre-split level, that our market capitalization will be equal to the market capitalization before the Reverse Split, or that we will be able to maintain our listing on Nasdaq.

Potential Disadvantages of the Reverse Split

As noted above, the principal purpose of the Reverse Split would be to help increase the per share market price of our common stock by up to factor of thirty five. We cannot assure you, however, that the Reverse Split will accomplish this objective for any meaningful period of time. While we expect that the reduction in the number of outstanding shares of common stock will increase the market price of our common stock, we cannot assure you that the Reverse Split will increase the market price of our common stock proportionately based on the Reverse Split ratio, or result in any permanent increase in the market price of our common stock, which is dependent upon many factors, including our business and financial performance, general market conditions and prospects for future success. If the per share market price does not increase proportionately as a result of the Reverse Split, then the value of our Company as measured by our market capitalization will be reduced, perhaps significantly.

The number of shares held by each individual holder of common stock would be reduced if the Reverse Split is implemented. This will increase the number of stockholders who hold less than a “round lot,” or 100 shares. Typically, the transaction costs to stockholders selling “odd lots” are higher on a per share basis. Consequently, the Reverse Split could increase the transaction costs to existing holders of common stock in the event they wish to sell all or a portion of their position.

Although our Board believes that the decrease in the number of shares of our common stock outstanding as a consequence of the Reverse Split and the anticipated increase in the market price of our common stock could encourage interest in our common stock and possibly promote greater liquidity for our stockholders, such liquidity could also be adversely affected by the reduced number of shares outstanding after the Reverse Split.

Effecting the Reverse Split

Upon receipt of stockholder approval for the Reverse Split Proposal, if our Board concludes that it is in the best interests of our Company and our stockholders to effect the Reverse Split, the Certificate of Amendment will be filed with the Secretary of State of Delaware. The actual timing of the filing of the Certificate of Amendment with the Secretary of State of Delaware to effect the Reverse Split will be determined by our Board. In addition, if for any reason our Board deems it advisable to do so, the Reverse Split may be abandoned at any time prior to the filing of the Certificate of Amendment, without further action by our stockholders. In addition, our Board may deem it advisable to effect the Reverse Split even if the price of our common stock is above $1.00 at the time the Reverse Split is to be effected. The Reverse Split will be effective as of the date of filing with the Secretary of State of the State of Delaware (the “Effective Time”).

7

Upon the filing of the Certificate of Amendment, without further action on our part or our stockholders, the outstanding shares of common stock held by stockholders of record as of the Effective Time would be converted into a lesser number of shares of common stock based on a Reverse Split ratio as determined by the Board. For example, if you presently hold 1,000 shares of our common stock, you would hold 200 shares of our common stock following the Reverse Split if the ratio is one-for-five or you would hold 40 shares of our common stock if the ratio is one-for-twenty five.

Effect on Outstanding Shares, Options and Certain Other Securities

If the Reverse Split is implemented, the percentage of our common stock owned by each stockholder will remain unchanged except for any de minimus change resulting from the treatment of fractional shares for which we will pay cash. The number of shares of our common stock that may be purchased upon exercise of outstanding options or exercise or conversion of other securities convertible into, or exercisable or exchangeable for, shares of our common stock, and the exercise or conversion prices for these securities, will also be ratably adjusted in accordance with their terms as of the Effective Time.

Effect on Registration

Our common stock is currently registered under the Securities Act of 1933, as amended, and we are subject to the periodic reporting and other requirements of the Securities Exchange Act of 1934, as amended. The proposed Reverse Split will not affect the registration of our common stock.

Fractional Shares; Exchange of Stock Certificates

Our Board does not currently intend to issue fractional shares of common stock in connection with the Reverse Split. Therefore, we do not expect to issue certificates representing fractional shares. In lieu of any fractional shares, we will pay the cash value of the fractional shares to the holders. For example, if a stockholder holds 150.25 shares of common stock following the Reverse Split, that stockholder will receive certificate representing 150 shares of common stock and a cash payment for the fair value of .25 shares as of the Effective Time.

As of the Record Date, we had 71 holders of record of our common stock (although we have significantly more beneficial holders). The Reverse Split may reduce the number of record holders depending on the ratio of the Reverse Split. We presently do not intend to seek any change in our status as a reporting company for federal securities law purposes, either before or after the Reverse Split.

On or after the Effective Time, we will mail a letter of transmittal to each stockholder. Each stockholder will be able to obtain a certificate evidencing his, her or its post-Reverse Split shares only by sending the exchange agent (who will be the Company’s transfer agent) the stockholder’s old stock certificate(s), together with the properly executed and completed letter of transmittal and such evidence of ownership of the shares as we may require. Stockholders will not receive certificates for post-Reverse Split shares unless and until their old certificates are surrendered. Stockholders should not forward their certificates to the exchange agent until they receive the letter of transmittal, and they should only send in their certificates with the letter of transmittal. The exchange agent will send each stockholder, if elected in the letter of transmittal, a new stock certificate after receipt of that stockholder’s properly completed letter of transmittal and old stock certificate(s). A stockholder that surrenders his, her or its old stock certificate(s) but does not elect to receive a new stock certificate in the letter of transmittal will be deemed to have requested to hold that stockholder’s shares electronically in book-entry form with our transfer agent.

Certain of our registered holders of common stock hold some or all of their shares electronically in book-entry form with our transfer agent. These stockholders do not have stock certificates evidencing their ownership of our common stock. They are, however, provided with a statement reflecting the number of shares registered in their accounts. If a stockholder holds registered shares in book-entry form with our transfer agent, the stockholder may return a properly executed and completed letter of transmittal.

Stockholders who hold shares in street name through a nominee (such as a bank or broker) will be treated in the same manner as stockholders whose shares are registered in their names, and nominees will be instructed to effect the Reverse Split for their beneficial holders. However, nominees may have different procedures and stockholders holding shares in street name should contact their nominees.

8

Stockholders will not have to pay any service charges in connection with the exchange of their certificates.

Anti-Takeover and Dilutive Effects

The authorized common stock and preferred stock will not be diluted as a result of the Reverse Split. The common stock and preferred stock that is authorized but unissued provide the Board with flexibility to effect among other transactions, public or private financings, acquisitions, stock dividends, stock splits and the granting of equity incentive awards. However, these authorized but unissued shares may also be used by our Board, consistent with and subject to its fiduciary duties, to deter future attempts to gain control of us or make such actions more expensive and less desirable. The Certificate of Amendment would continue to give our Board authority to issue additional shares from time to time without delay or further action by the stockholders except as may be required by applicable law or regulations. The Certificate of Amendment is not being recommended in response to any specific effort of which we are aware to obtain control of us, nor does our Board have any present intent to use the authorized but unissued common stock or preferred stock to impede a takeover attempt. There are no plans or proposals to adopt other provisions or enter into any arrangements that have material anti-takeover effects.

Accounting Consequences

As of the Effective Time, the stated capital attributable to common stock on our balance sheet will be reduced proportionately based on the Reverse Split ratio (including a retroactive adjustment of prior periods), and the additional paid-in capital account will be credited with the amount by which the stated capital is reduced. Reported per share net income or loss will be higher because there will be fewer shares of our common stock outstanding.

Federal Income Tax Consequences

The following summary describes certain material U.S. federal income tax consequences of the Reverse Split to holders of our common stock. This summary addresses the tax consequences only to a beneficial owner of our common stock that is a citizen or individual resident of the United States, a corporation organized in or under the laws of the United States or any state thereof or the District of Columbia or otherwise subject to U.S. federal income taxation on a net income basis in respect of our common stock (a “U.S. holder”). This summary does not address all of the tax consequences that may be relevant to any particular stockholder, including tax considerations that arise from rules of general application to all taxpayers or to certain classes of taxpayers or that are generally assumed to be known by investors. This summary also does not address the tax consequences to persons who may be subject to special treatment under U.S. federal income tax law or persons that do not hold our common stock as “capital assets” (generally, property held for investment). This summary is based on the provisions of the Internal Revenue Code of 1986, as amended, U.S. Treasury regulations, administrative rulings and judicial authority, all as in effect as of the date hereof. Subsequent developments in U.S. federal income tax law, including changes in law or differing interpretations, which may be applied retroactively, could have a material effect on the U.S. federal income tax consequences of the Reverse Split.

If a partnership (or other entity classified as a partnership for U.S. federal income tax purposes) is the beneficial owner of our common stock, the U.S. federal income tax treatment of a partner in the partnership will generally depend on the status of the partner and the activities of the partnership. Partnerships that hold our common stock, and partners in such partnerships, should consult their own tax advisors regarding the U.S. federal income tax consequences of the Reverse Split.

Each stockholder should consult his, her or its own tax advisor regarding the U.S. federal, state, local and foreign income and other tax consequences of the Reverse Split.

The Reverse Split should be treated as a recapitalization for U.S. federal income tax purposes. Therefore, no gain or loss should be recognized by a U.S. holder upon the Reverse Split. Accordingly, the aggregate tax basis in the common stock received pursuant to the Reverse Split should equal the aggregate tax basis in the common stock surrendered and the holding period for the common stock received should include the holding period for the common stock surrendered.

FAQ

What new proposal is enVVeno Medical (NVNO) adding to its 2025 annual meeting?

Proposal 5 asks stockholders to grant the Board authority to implement a reverse stock split of enVVeno Medical’s common stock at a ratio between one-for-five and one-for-thirty-five, at a time and exact ratio to be chosen by the Board in its sole discretion if the proposal is approved.

Why is enVVeno Medical (NVNO) seeking approval for a reverse stock split?

The Board states that the main purpose is to raise the per-share trading price of the common stock to comply with Nasdaq’s minimum bid requirement of $1.00 per share. The company has received a Nasdaq notice because its closing bid price was below $1.00 for 30 consecutive business days, and it reports a closing price of $0.3297 on November 18, 2025.

How would the proposed reverse stock split affect enVVeno Medical’s outstanding shares?

Based on 20,216,176 common shares outstanding as of the record date, a one-for-five reverse split would reduce the outstanding shares to approximately 4,043,235, while a one-for-thirty-five split would reduce them to about 577,605. Each stockholder is expected to hold roughly the same ownership percentage, aside from cash paid instead of issuing fractional shares.

Will the reverse stock split change enVVeno Medical’s authorized share count or voting rights?

The company states that the reverse split will not change the authorized number of common or preferred shares, so the number of authorized but unissued shares would increase. The relative voting and other rights associated with the shares are described as remaining the same, other than small effects from handling fractional shares.

What voting approval is required for enVVeno Medical’s reverse split proposal?

Approval of Proposal 5 requires the affirmative vote of holders of a majority in voting power of the shares that are present in person or by proxy and entitled to vote on the proposal. Abstentions count as present and will have the effect of a vote against the proposal, and brokers may vote on this routine matter if they do not receive instructions from beneficial owners.

What change did enVVeno Medical make to its quorum requirement for stockholder meetings?

On November 17, 2025, the Board amended the company’s bylaws to reduce the quorum requirement from a majority of outstanding voting shares to thirty three and one-third percent of outstanding voting shares entitled to vote at the meeting.

How can enVVeno Medical (NVNO) stockholders vote on the new reverse split proposal?

To vote on Proposal 5, stockholders must either attend the virtual annual meeting or submit a new proxy card that includes all five proposals, or vote by Internet or telephone as described in the materials. Submitting the new proxy card or voting again revokes any prior proxy; if no choices are marked, shares represented by the new proxy will be voted FOR all director nominees and FOR Proposals 2 through 5.
