Securities Purchase Agreement

On November 24, 2025, Enlivex Therapeutics Ltd., a company organized under the laws of the State of Israel (the “Company”), entered into a securities purchase agreement (the “Securities Purchase Agreement”) with certain accredited investors (the “Purchasers”), pursuant to which the Company has agreed to sell and issue to the Purchasers in a private placement (the “Private Placement”) an aggregate of 212,000,000 ordinary shares, par value NIS 0.40 per share, of the Company (the “Ordinary Shares” and such Ordinary Shares issued in the Private Placement, the “Shares”), or pre-funded warrants in lieu of Shares to purchase Ordinary Shares (the “Pre-Funded Warrants” and the Ordinary Shares issuable upon exercise thereof, the “Pre-Funded Warrant Shares” and, together with the Shares and the Pre-Funded Warrants, the “Securities”) at a purchase price of $1.00 per Share or $0.999 per Pre-Funded Warrant in lieu thereof. The Purchasers have agreed to pay the applicable purchase price in U.S. dollars, Tether (USDT), or a combination thereof.

Each Pre-Funded Warrant has an exercise price of $0.001 per Ordinary Share, is immediately exercisable, may be exercised at any time and has no expiration date. The exercise price and the number of Pre-Funded Warrant Shares issuable upon exercise of each Pre-Funded Warrant are subject to appropriate adjustment in the event of certain share dividends, share splits, share combinations or similar events affecting the Ordinary Shares. The Pre-Funded Warrants may not be exercised if, after giving effect to such exercise, the aggregate number of Ordinary Shares beneficially owned by the holder thereof (together with its affiliates and certain attribution parties) would exceed a specified beneficial ownership limitation; provided, however, that a holder may increase or decrease such beneficial ownership limitation by giving notice to the Company (with any increase becoming effective only after 61 days), but not to any percentage in excess of 9.99%.

The initial closing of the Private Placement occurred prior to the opening of trading on the Nasdaq Capital Market on November 24, 2025 (the “Initial Closing Date”), and the final closing of the Private Placement is expected to occur after the close of trading on the Nasdaq Capital Market on November 24, 2025 (the “Final Closing Date”), subject to the satisfaction of customary closing conditions.

In connection with the Private Placement, the Company announced that it will use the proceeds of the Private Placement to implement its long-term digital asset treasury strategy designed to support its operational needs while aligning its reserve management practices with the development of the RAIN ecosystem. Under the Company’s digital asset treasury strategy, the Company intends to maintain a portfolio composed primarily of RAIN tokens, together with a complementary allocation to stablecoins and other short-duration digital assets intended to provide liquidity and capital stability. Pursuant to the Securities Purchase Agreement, the Company has agreed to use substantially all of the net proceeds from the Private Placement to purchase RAIN and for the establishment of the Company’s cryptocurrency treasury operations with respect to the Company’s digital asset treasury strategy, as well as to pay all transaction fees and expenses.

The Securities Purchase Agreement contains customary representations, warranties and agreements by the Company, customary conditions to closing, indemnification obligations of the Company, other obligations of the parties and termination provisions.

Pursuant to the Securities Purchase Agreement, the Company has agreed to certain restrictions on the issuance and sale of the Company’s securities for a period beginning on the date of the Securities Purchase Agreement until the thirtieth (30th) day following the Final Closing Date.

The offer and sale of the Securities have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or any state securities laws and have been offered and will be sold pursuant to the exemption from registration provided for under Section 4(a)(2) of the Securities Act or Rule 506 of Regulation D promulgated thereunder. The Company relied on this exemption from registration based in part on representations made by the Purchasers, including that each purchaser is an “accredited investor” as defined Rule 501(a) promulgated under the Securities Act. The Securities may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements.

Registration Rights Agreement

In connection with the Private Placement, the Company and the Purchasers have agreed to enter into a Registration Rights Agreement (the “Registration Rights Agreement”), providing for the registration of the Shares and the Pre-Funded Warrant Shares for resale on a registration statement (the “Resale Registration Statement”) to be filed by the Company with the Securities and Exchange Commission (the “SEC”) no later than the 30^th calendar day following the Final Closing Date. The Company has agreed to use reasonable best efforts to cause the Resale Registration Statement to be declared effective as promptly as possible and to keep the Resale Registration Statement continuously effective until the earlier of (i) the date on which the Purchasers shall have resold or otherwise disposed of all the securities covered thereby, or (ii) the date on which the Securities may be resold by the Purchasers without registration and without regard to any volume or manner-of-sale limitations by reason of Rule 144, without the requirement for the Company to be in compliance with the current public information requirement under Rule 144 or any other rule of similar effect.

The foregoing descriptions of the Securities Purchase Agreement, Registration Rights Agreement and the Pre-Funded Warrant are only summaries and are qualified in their entirety by reference to the complete text of the forms of Securities Purchase Agreement, Registration Rights Agreement and Pre-Funded Warrant, which are filed as Exhibit 10.1, Exhibit 10.2 and Exhibit 4.1, respectively, to this Current Report on Form 6-K and incorporated by reference herein.

Treasury Management Agreement

On November 20, 2025, the Company entered into an asset management agreement (the “Treasury Management Agreement”) with Elinnovation Labs Ltd., a company organized under the laws of the State of Israel (the “Asset Manager”). Pursuant to the Treasury Management Agreement, the Company appointed the Asset Manager to provide asset management services with respect to certain cash proceeds of the Private Placement and the Company’s future securities offerings and other capital the Company may from time to time designate, together with digital assets and other assets acquired with or in respect of such proceeds (the “Account Assets”) held in accounts and cryptocurrency wallets controlled by the Company.

As compensation for its services, the Asset Manager is entitled to specified management fees. Subject to the terms of the Treasury Management Agreement, the Asset Manager is responsible for its own overhead and for the fees and expenses of any custodian, and the Company is obligated to reimburse only certain pre-approved, reasonable and documented out-of-pocket expenses incurred on the Asset Manager’s behalf.

The Treasury Management Agreement has an initial term of three years and renews for successive one-year periods unless the Company or the Asset Manager terminates or elects not to continue the Treasury Management Agreement in accordance with its terms, including the ability of either party to terminate without cause after the first anniversary upon prior written notice and to terminate earlier for specified causes, including certain acts of fraud, bad faith, gross negligence, material breach or insolvency. The Treasury Management Agreement also contains customary representations, covenants, confidentiality, indemnification and limitation of liability provisions.

The foregoing description of the Treasury Management Agreement is only a summary and is qualified in its entirety by reference to the full text of the Treasury Management Agreement, a copy of which is attached hereto as Exhibit 10.3 and incorporated herein by reference.

Shareholders’ Agreement

On the Final Closing Date, the Company will enter into a Shareholders’ Agreement (the “Shareholders’ Agreement”) with certain of the Purchasers (the “Shareholders”) in connection with the transactions contemplated by the Securities Purchase Agreement. Pursuant to the Shareholders’ Agreement, the Shareholders will agree that they will not transfer any of the Ordinary Shares or Pre-Funded Warrant Shares acquired under the Securities Purchase Agreement (the “Restricted Securities”) during the period beginning on the date of the Shareholders’ Agreement and expiring (i) with respect to 20% of the Restricted Securities, on the effective date of the Resale Registration Statement and (ii) with respect to the remaining 80% of the Restricted Securities, ratably on a daily basis over the six-month period commencing on the six-month anniversary of such date, subject to customary permitted transfers to certain affiliates and estate-planning vehicles that agree to be bound by the Shareholders’ Agreement.

In addition, in consideration of Sobrinia Ltd.’s (“Sobrinia”) efforts in connection with structuring the Company’s digital asset treasury strategy, the Shareholders’ Agreement provides that the Company will issue to Sobrinia a five-year warrant to purchase up to an aggregate of 1,750,000 Ordinary Shares at an exercise price of $1.00 per share (the “Lead Investor Warrants”). The Shareholders’ Agreement also includes certain use-of-proceeds covenants relating to the Company’s digital asset treasury strategy, provides that each Shareholder agrees to vote its shares in favor of specified amendments to the Company’s articles of association and indemnification arrangements for directors and officers at an extraordinary general meeting of shareholders to be convened following the closing of the Private Placement, and grants an irrevocable proxy to the Company’s chairman to vote such shares in favor of such matters if a Shareholder does not do so.

The offer and sale of the Lead Investor Warrants and the Ordinary Shares issuable upon exercise thereof have not been registered under the Securities Act or any state securities laws and have been offered and will be sold pursuant to the exemption from registration provided for under Section 4(a)(2) of the Securities Act or Rule 506 of Regulation D promulgated thereunder. The Company relied on this exemption from registration based in part on representations made by Sobrinia, including that it is an “accredited investor” as defined Rule 501(a) promulgated under the Securities Act. The Lead Investor Warrants may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements

The foregoing descriptions of the Shareholders’ Agreement and Lead Investor Warrants are only summaries and are qualified in their entirety by reference to the complete text of the forms of the Shareholders’ Agreement and Lead Investor Warrants, which are filed as Exhibit 10.4 and Exhibit 4.2, respectively, to this Current Report on Form 6-K and incorporated by reference herein.
