Description of Ordinary Shares

General

This prospectus describes the general terms of our ordinary shares, which description is qualified in its entirety by reference to applicable Israeli law and the terms and provisions contained in our amended and restated articles of association. When we offer to sell ordinary shares, we will describe the specific terms of such offering in a supplement to this prospectus. Accordingly, for a description of the terms of a particular offering of our ordinary shares, you must refer to both this prospectus and the applicable prospectus supplement. To the extent the information contained in the prospectus supplement differs from this summary description, you should rely on the information contained in the prospectus supplement.

Under our amended and restated articles of association, the total number of shares of all classes of stock that we have authority to issue is 500,000,000 ordinary shares with a par value of NIS 0.40 per share. As of December 15, 2025, there were 237,381,498 ordinary shares outstanding.

Rights, Preferences, Restrictions of Shares and Shareholders Meetings

Modification of Class Rights

If, at any time, the share capital is divided into different classes of shares, the rights attached to any class (unless otherwise provided by the terms of issuance of the shares of that class) may be varied with the consent in writing of the holders of all the issued shares of that class, or with the sanction of a majority vote at a meeting of the shareholders passed at a separate meeting of the holders of the shares of that class. The provisions of our amended and restated articles of association relating to general meetings shall apply, mutatis mutandis, to every such separate class meeting.

Unless otherwise provided by the conditions of issuance, the enlargement of an existing class of shares, or the issuance of additional shares thereof, shall not be deemed to modify or abrogate the rights attached to the previously issued shares of such class or of any other class. These conditions provide for the minimum shareholder approvals permitted by the Companies Law.

Restrictions on Shareholders Rights to Own Securities

Our amended and restated articles of association and the laws of the State of Israel do not restrict in any way the ownership or voting or our shares by non-residents of Israel, except with respect to subjects of countries which are in a state of war with Israel.

Securities Register

We are registered with the Israeli Registrar of Companies. Our registration number is 51-471648-9. Our amended and restated articles of association provide that we may engage in any type of lawful business.

Board of Directors

The Companies Law requires that certain transactions, actions and arrangements be approved as provided for in a company’s articles of association and in certain circumstances by the Company’s Audit Committee or the Company’s Compensation Committee, by the Board of Directors itself and by the shareholders. The vote required by the Audit Committee, Compensation Committee and the Board of Directors for approval of such matters, in each case, is a majority of the disinterested directors participating in a duly convened meeting. If, however, a majority of the members participating in such meeting have a personal interest in the approval of such matter, then all directors may participate in the discussions and the voting on approval thereof and in such case the matter shall be subject to further shareholder approval.

The Companies Law requires that an office holder promptly disclose to the Company any personal interest that he or she may have and all related material information or documents relating to any existing or proposed transaction by the Company. An interested office holder’s disclosure must be made promptly and in any event no later than the first meeting of the Board of Directors at which the transaction is considered. An office holder is not obliged to disclose such information if the personal interest of the office holder derives solely from the personal interest of his or her relative in a transaction that is not considered as an extraordinary transaction.

The term “personal interest” is defined under the Companies Law to include the personal interest of a person in an action or in the business of a company, including the personal interest of such person’s relative or the interest of any corporation in which the person is an interested party, but excluding a personal interest stemming solely from the fact of holding shares in such company. A personal interest furthermore includes the personal interest of a person for whom the office holder holds a voting proxy or the interest of the office holder with respect to his or her vote on behalf of the shareholder for whom he or she holds a proxy even if such shareholder itself has no personal interest in the approval of the matter.

Under the Companies Law, an extraordinary transaction is defined as any of the following:

If it is determined that an office holder has a personal interest in a transaction that is not an extraordinary transaction, approval by the board of directors is required for the transaction, unless the company’s articles of association provide for a different method of approval. Approval first by the company’s Audit Committee and subsequently by the board of directors is required for an extraordinary transaction in which an office holder has a personal interest. Further, so long as an office holder has disclosed his or her personal interest in a transaction, the board of directors may approve an action by the office holder that would otherwise be deemed a breach of duty of loyalty. However, a company may not approve a transaction or action that is adverse to the company’s interest or that is not performed by the office holder in good faith. Arrangements regarding the compensation, indemnification or insurance of an office holder require the approval of the Compensation Committee, board of directors and, in certain circumstances, the shareholders, in that order.

Pursuant to Israeli law, the disclosure requirements regarding personal interests that apply to directors and executive officers also apply to a controlling shareholder of a public company. In the context of a transaction involving a controlling shareholder or an officer who is a controlling shareholder of the company, a controlling shareholder also includes any shareholder who holds 25% or more of the voting rights if no other shareholder holds more than 50% of the voting rights. Two or more shareholders with a personal interest in the approval of the same transaction are deemed to be a single shareholder and may be deemed a controlling shareholder for the purpose of approving such transaction. Extraordinary transactions, including private placement transactions, with a controlling shareholder or in which a controlling shareholder has a personal interest, and engagements with a controlling shareholder or his or her relative, directly or indirectly, including through a corporation in his or her control, require the approval of the Audit Committee, the Board of Directors and the shareholders of the company, in that order. In addition, the shareholder approval must fulfill one of the following requirements:

To the extent that any such transaction with a controlling shareholder is for a period extending beyond three years, approval is required once every three years, unless the Audit Committee determines that the duration of the transaction is reasonable given the circumstances related thereto.

Arrangements regarding the terms of engagement and compensation of a controlling shareholder who is an office holder, and the terms of employment of a controlling shareholder who is an employee of the company, require the approval of the Compensation Committee, Board of Directors and, generally, the shareholders (by the same special majority described above), in that order.

Pursuant to Israeli law, a director who has a personal interest in an extraordinary transaction which is brought for discussion before our Board of Directors or our Audit Committee shall neither vote in nor attend discussions concerning the approval of such transaction. If the director did vote or attend as aforesaid, the approval given to the aforesaid activity or arrangement will be invalid.

Our amended and restated articles of association provide that, subject to the Companies Law, our Board of Directors may delegate its authority, in whole or in part, to such committees of the Board of Directors as it deems appropriate, and it may from time to time revoke such delegation. To the extent permitted by the Companies Law, our Board of Directors may from time to time confer upon and delegate to a President, Chief Executive Officer, Chief Operating Officer or other executive officer then holding office, such authorities and duties of the Board of Directors as it deems fit, and they may delegate such authorities and duties for such period and for such purposes and subject to such conditions and restrictions which they consider in our best interests, without waiving the authorities of the Board of Directors with respect thereto.

Arrangements regarding compensation of directors require the approval of our Compensation Committee, our Board of Directors and the shareholders.

Acquisitions under Israeli Law

Full tender offer

A person wishing to acquire shares of an Israeli public company and who would as a result hold over 90% of the target company’s issued and outstanding share capital or of the issued and outstanding share capital of a certain class of shares is required by the Companies Law to make a tender offer to all of the company’s shareholders for the purchase of all of the issued and outstanding shares of the company or of all of the issued and outstanding shares of the same class.

If the shareholders who do not respond to or do not accept the offer hold less than 5% of the issued and outstanding share capital of the company or of the applicable class of the shares, and more than half of the shareholders who do not have a personal interest in the offer accept the offer, all of the shares that the acquirer offered to purchase will be transferred to the acquirer by operation of law. However, a tender offer also will be accepted if the shareholders who do not accept it hold less than 2% of the issued and outstanding share capital of the company or of the applicable class of the shares.

Upon a successful completion of such a full tender offer, any shareholder that was an offeree in such tender offer, whether such shareholder accepted the tender offer or not, may, within six months from the date of acceptance of the tender offer, petition the Israeli court to determine whether the tender offer was for less than fair value and that the fair value should be paid as determined by the court. However, under certain conditions, the offeror may include in the terms of the tender offer that an offeree who accepted the offer will not be entitled to petition the Israeli court as described above.

If (a) the shareholders who did not respond or accept the tender offer hold at least 5% of the issued and outstanding share capital of the company or of the applicable class or the shareholders who accept the offer constitute less than a majority of the offerees that do not have a personal interest in the acceptance of the tender offer, or (b) the shareholders who did not accept the tender offer hold 2% or more of the issued and outstanding share capital of the company (or of the applicable class), the acquirer may not acquire shares of the company that will increase its holdings to more than 90% of the company’s issued and outstanding share capital or of the applicable class from shareholders who accepted the tender offer.

Special tender offer

The Companies Law provides that an acquisition of shares of an Israeli public company must be made by means of a special tender offer if as a result of the acquisition the purchaser would become a holder of at least 25% of the voting rights in the company. This rule does not apply if there is already another holder of at least 25% of the voting rights in the company.

Similarly, the Companies Law provides that an acquisition of shares in a public company must be made by means of a special tender offer if as a result of the acquisition the purchaser would become a holder of more than 45% of the voting rights in the company, if there is no other shareholder of the company who holds more than 45% of the voting rights in the company.

These requirements do not apply if the acquisition (i) occurs in the context of a private offering, on the condition that the shareholders meeting approved the acquisition as a private offering whose purpose is to give the acquirer at least 25% of the voting rights in the company if there is no person who holds at least 25% of the voting rights in the company, or as a private offering whose purpose is to give the acquirer 45% of the voting rights in the company, if there is no person who holds 45% of the voting rights in the company; (ii) was from a shareholder holding at least 25% of the voting rights in the company and resulted in the acquirer becoming a holder of at least 25% of the voting rights in the company; or (iii) was from a holder of more than 45% of the voting rights in the company and resulted in the acquirer becoming a holder of more than 45% of the voting rights in the company.

The special tender offer may be consummated only if (i) at least 5% of the voting power attached to the company’s outstanding shares will be acquired by the offeror and (ii) the special tender offer is accepted by a majority of the votes of those offerees who gave notice of their position in respect of the offer; in counting the votes of offerees, the votes of a holder of control in the offeror, a person who has personal interest in acceptance of the special tender offer, a holder of at least 25% of the voting rights in the company, or any person acting on their or on the offeror’s behalf, including their relatives or companies under their control, are not taken into account.

In the event that a special tender offer is made, a company’s board of directors is required to express its opinion on the advisability of the offer or shall abstain from expressing any such opinion if it is unable to do so, provided that it gives the reasons for its abstention.

An office holder in a target company who, in his or her capacity as an office holder, performs an action the purpose of which is to cause the failure of an existing or foreseeable special tender offer or is to impair the chances of its acceptance, is liable to the potential purchaser and shareholders for damages resulting from his acts, unless such office holder acted in good faith and had reasonable grounds to believe he or she was acting for the benefit of the company. However, office holders of the target company may negotiate with the potential purchaser in order to improve the terms of the special tender offer, and may further negotiate with third parties in order to obtain a competing offer.

If a special tender offer was accepted by a majority of the shareholders who announced their stand on such offer, then shareholders who did not respond to the special offer or had objected to the special tender offer may accept the offer within four days of the last day set for the acceptance of the offer.

In the event that a special tender offer is accepted, then the purchaser or any person or entity controlling it and any corporation controlled by them shall refrain from making a subsequent tender offer for the purchase of shares of the target company and may not execute a merger with the target company for a period of one year from the date of the offer, unless the purchaser or such person or entity undertook to effect such an offer or merger in the initial special tender offer.

Merger

The Companies Law permits merger transactions if approved by each party’s Board of Directors and, unless certain requirements described under the Companies Law are met, a majority of each party’s shareholders, by a majority of each party’s shares that are voted on the proposed merger at a shareholders’ meeting.

The Board of Directors of a merging company is required pursuant to the Companies Law to discuss and determine whether in its opinion there exists a reasonable concern that as a result of a proposed merger, the surviving company will not be able to satisfy its obligations towards its creditors, taking into account the financial condition of the merging companies. If the Board of Directors has determined that such a concern exists, it may not approve a proposed merger. Following the approval of the Board of Directors of each of the merging companies, the Boards of Directors must jointly prepare a merger proposal for submission to the Israeli Registrar of Companies.

For purposes of the shareholder vote, unless a court rules otherwise, the merger will not be deemed approved if a majority of the shares represented at the shareholders meeting that are held by parties other than the other party to the merger, or by any person who holds 25% or more of the outstanding shares or the right to appoint 25% or more of the directors of the other party, vote against the merger.

If the transaction would have been approved but for the separate approval of each class of shares or the exclusion of the votes of certain shareholders as provided above, a court may still rule that the company has approved the merger upon the request of holders of at least 25% of the voting rights of a company, if the court holds that the merger is fair and reasonable, taking into account the appraisal of the merging companies’ value and the consideration offered to the shareholders.

Under the Companies Law, each merging company must send a copy of the merger proposal to its secured creditors. Unsecured creditors are entitled to receive notice of the merger, as provided by the regulations promulgated under the Companies Law. Upon the request of a creditor of either party to the proposed merger, the court may delay or prevent the merger if it concludes that there exists a reasonable concern that, as a result of the merger, the surviving company will be unable to satisfy the obligations of the target company. The court may also give instructions in order to secure the rights of creditors.

In addition, a merger may not be completed unless at least 50 days have passed from the date that a proposal for approval of the merger was filed with the Israeli Registrar of Companies and 30 days from the date that shareholder approval of both merging companies was obtained.

Potential Issues that Could Delay a Merger

Certain provisions of Israeli corporate and tax law may have the effect of delaying, preventing or making more difficult any merger or acquisition of us.

Requirement of Disclosure of Shareholder Ownership

There are no provisions of our amended and restated articles of association governing the ownership threshold above which shareholder ownership must be disclosed. We are subject, however, to U.S. securities rules that require beneficial owners of more than 5% of our ordinary shares to make certain filings with the SEC.

Changes in Capital

Our amended and restated articles of association do not impose any conditions governing changes in capital that are more stringent than required by the Companies Law.

Listing

Our ordinary shares are listed on the Nasdaq Capital Market, which is the primary exchange for our shares based on average daily trading volume, under the symbol “ENLV” and on the Tel Aviv Stock Exchange under the symbol “ENLV.”

Selling Shareholders

The ordinary shares being offered by the Selling Shareholders are those previously issued to the Selling Shareholders, or those issuable to certain of the Selling Shareholders upon exercise of the Pre-Funded Warrants. For additional information regarding the issuances of those ordinary shares, see the section of this prospectus titled “Prospectus Summary—Recent Developments.” We are registering the ordinary shares in order to permit the Selling Shareholders to offer the ordinary shares for resale from time to time.

Information About the Selling Shareholders.

The following table sets forth, based on information provided to us by or on behalf of the Selling Shareholders or known to us, the names of the Selling Shareholders and the number of ordinary shares beneficially owned by the Selling Shareholders before and after this offering.

The table below lists the Selling Shareholders and other information regarding the beneficial ownership (as determined under Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations thereunder) of the ordinary shares held by each of the Selling Shareholders.

The Selling Shareholders are not obligated to sell any ordinary shares. The Selling Shareholders may sell all, some or none of ordinary shares covered by this prospectus in this offering. See “Plan of Distribution.” The beneficial ownership of the Selling Shareholders in the table below is based upon 237,381,498 ordinary shares outstanding as of December 15, 2025.

Beneficial ownership is determined according to the rules of the SEC, which generally provide that a person has beneficial ownership of a security if such person possesses sole or shared voting or investment power over that security, including derivative securities, such as options and warrants, that are currently exercisable or become exercisable within 60 days. In computing the number of shares beneficially owned by a particular Selling Shareholder and the percentage ownership of that Selling Shareholder in the table below, all ordinary shares subject to options and warrants held by such Selling Shareholder were deemed outstanding if such securities are currently exercisable or become exercisable within 60 days following of December 15, 2025. These ordinary shares were not deemed outstanding, however, for the purpose of computing the percentage ownership of any other Selling Shareholder.

A Selling Shareholder may not exercise the Pre-Funded Warrants to the extent such exercise would result in such Selling Shareholder, together with its affiliates and attribution parties, beneficially owning a number of ordinary shares that exceeds 9.99% of our then outstanding ordinary shares following such exercise. The number of shares in the first and third columns do not reflect this limitation.

Unless otherwise noted, the business address of each of these shareholders is c/o Enlivex Therapeutics Ltd., 14 Einstein Street, Nes Ziona, Israel 7403618

Relationships with the Selling Shareholders

The Selling Shareholders have not had any material relationships with our officers, directors, or affiliates over the past three years, except (i) for the ownership of the ordinary shares and the Pre-Funded Warrants, (ii) as described in the section of this prospectus titled “Prospectus Summary—Recent Developments,” and (iii) as described in this section and in the table and footnotes above.

Taxation

The material Israeli and U.S. federal income tax consequences relating to the purchase, ownership and disposition of any of the securities offered by this prospectus is incorporated by reference from our Annual Report on Form 20-F for the year ended December 31, 2024 and any superseding disclosure contained in our subsequent public filings with the SEC.

Plan of Distribution

Each Selling Shareholder and any of their pledgees, donees, transferees, assignees, and other successors-in-interest may, from time to time, sell any or all of their securities covered hereby on the principal trading market or any other stock exchange, market or trading facility on which the Securities are traded or in private transactions. These sales may be at fixed or negotiated prices. The Selling Shareholders will act independently of us in making decisions with respect to the timing, manner and size of each sale. Such sales may be made on one or more exchanges or in the over-the-counter market or otherwise, at prices and under terms then prevailing or at prices related to the then current market price or in negotiated transactions. The Selling Shareholders reserve the right to accept and, together with their respective agents, to reject, any proposed purchase of securities to be made directly or through agents. The Selling Shareholders and any permitted transferees may sell their securities offered by this prospectus on any stock exchange, market or trading facility on which the securities are traded or in private transactions. A Selling Shareholder may use any one or more of the following methods when selling securities:

The Selling Shareholders may also sell securities under Rule 144 or any other exemption from registration under the Securities Act, if available, rather than under this prospectus.

There can be no assurance that any Selling Shareholder will sell any or all of the Ordinary Shares registered pursuant to the registration statement of which this prospectus forms a part.

In addition, a Selling Shareholder that is an entity may elect to make an in-kind distribution of securities to its members, partners or stockholders pursuant to the registration statement of which this prospectus is a part by delivering a prospectus with a plan of distribution. Such members, partners or stockholders would thereby receive freely tradeable securities pursuant to the distribution through a registration statement. To the extent a distributee is an affiliate of ours (or to the extent otherwise required by law), we may file a prospectus supplement in order to permit the distributees to use the prospectus to resell the securities acquired in the distribution.

The Selling Shareholders also may transfer the securities in other circumstances, in which case the transferees, pledgees or other successors-in-interest will be the selling beneficial owners for purposes of this prospectus. Upon being notified by the Selling Shareholders that a donee, pledgee, transferee, other successor-in-interest intends to sell our securities, we will, to the extent required, promptly file a supplement to this prospectus to name specifically such person as a Selling Shareholder.

Broker-dealers engaged by the Selling Shareholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the Selling Shareholders (or, if any broker-dealer acts as agent for the purchaser of securities, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with FINRA Rule 2121; and in the case of a principal transaction a markup or markdown in compliance with FINRA Rule 2121.

In connection with the sale of the securities or interests therein, the Selling Shareholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the securities in the course of hedging the positions they assume. The Selling Shareholders may also sell securities short and deliver these securities to close out their short positions, or loan or pledge the securities to broker-dealers that in turn may sell these securities. The Selling Shareholders may also enter into option or other transactions with broker- dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The Selling Shareholders and any broker-dealers or agents that are involved in selling the securities may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the securities purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Each Selling Shareholder has informed the Company that it does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the securities.

We are required to pay certain fees and expenses incurred by the Company incident to the registration of the Securities. The Company has agreed to indemnify the Selling Shareholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act. The Company shall not be responsible for any of the Selling Shareholders’ selling costs incurred pursuant to any available method provided hereunder for selling securities.

We are obligated to maintain the effectiveness of this registration statement until all of the ordinary shares registered pursuant to it (i) have been sold, hereunder or pursuant to Rule 144, or (ii) may be sold without volume or manner-of-sale restrictions pursuant to Rule 144 and without the requirement for us to be in compliance with the current public information requirement under Rule 144. The resale securities will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale securities covered hereby may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the resale securities may not simultaneously engage in market making activities with respect to the Ordinary Shares for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the Selling Shareholders will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of the Ordinary Shares by the Selling Shareholders or any other person. We will make copies of this prospectus available to the Selling Shareholders and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).

Expenses

The following table sets forth the expenses (other than underwriting discounts and commissions or agency fees and other items constituting underwriters’ or agents’ compensation, if any) expected to be incurred by us in connection with a possible offering of securities registered under this registration statement.

Legal Matters

The validity of the securities offered hereby will be passed upon for us by FISCHER (FBC & Co.), Tel Aviv, Israel. Certain matters of U.S. federal law will be passed upon for us by Greenberg Traurig, P.A., Miami, Florida.

Experts

Our consolidated financial statements included in our Annual Report on Form 20-F for the year ended December 31, 2024 are incorporated herein by reference in reliance on the report of Yarel + Partners, an independent registered public accounting firm, given on the authority of such firm as an expert in accounting and auditing.

Enforceability of Civil Liabilities

We are incorporated under the laws of the State of Israel. Service of process upon us and upon our directors and officers and any Israeli experts named in this registration statement, most of whom reside outside of the United States, may be difficult to obtain within the United States. Furthermore, because substantially all of our assets and most of our directors and officers are located outside of the United States, any judgment obtained in the United States against us or certain of our directors and officers may be difficult to collect within the United States.

We have been informed by our legal counsel in Israel, FISCHER (FBC & Co.), that it may be difficult to assert U.S. securities law claims in original actions instituted in Israel. Israeli courts may refuse to hear a claim based on an alleged violation of U.S. securities laws on the grounds that Israel is not the most appropriate forum to bring such a claim. In addition, even if an Israeli court agrees to hear a claim, it may determine that Israeli law and not U.S. law is applicable to the claim. If U.S. law is found to be applicable, the content of applicable U.S. law must be proved as a fact by expert witnesses which can be a time-consuming and costly process. Certain matters of procedure will also be governed by Israeli law.

Subject to specified time limitations and legal procedures, Israeli courts may enforce a United States judgment in a civil matter which (subject to limited exceptions) is non-appealable, including a judgment based upon the civil liability provisions of the Securities Act or the Exchange Act and including a monetary or compensatory judgment in a non-civil matter, provided that, among other things:

Even if these conditions are met, an Israeli court may not declare a foreign civil judgment enforceable if:

If a foreign judgment is enforced by an Israeli court, it generally will be payable in Israeli currency, which can then be converted into non-Israeli currency and transferred out of Israel. The usual practice in an action before an Israeli court to recover an amount in a non-Israeli currency is for the Israeli court to issue a judgment for the equivalent amount in Israeli currency at the rate of exchange in force on the date of the judgment, but the judgment debtor may make payment in foreign currency. Pending collection, the amount of the judgment of an Israeli court stated in Israeli currency ordinarily will be linked to the Israeli consumer price index plus interest at the annual statutory rate set by Israeli regulations prevailing at the time. Judgment creditors must bear the risk of unfavorable exchange rates.
