This Report on Form 6-K, excluding of the press release attached hereto as Exhibit 99.4, is hereby incorporated by reference into the registrant’s Registration Statements on Form S-8 (File Nos. 333-227753, 333-271384 and 333-278525) and Form F-3 (File Nos. 333-236064, 333-274316, 333-262055, 333-276000 and 333-281872), to be a part thereof from the date on which this report is submitted, to the extent not superseded by documents or reports subsequently filed or furnished.

On March 4, 2026, Can-Fite Biopharma Ltd. (the “Company”) entered into an inducement offer letter agreement (the “Inducement Letter”) with a certain holder (the “Holder”) of certain of the Company’s existing warrants to purchase up to 795,869 of the Company’s American Depositary Shares (“ADS”), each ADS representing two ordinary shares, no par value, issued on July 29, 2025 at an exercise price of $9.34 per ADS (the “Existing Warrants”).

Pursuant to the Inducement Letter, the Holder agreed to exercise for cash its Existing Warrants to purchase an aggregate of 795,869 of the Company’s ADSs at a reduced exercise price of $5.00 per ADS in consideration of the Company’s agreement to issue new warrants to purchase ADSs (the “New Warrants”), as described below, to purchase up to an aggregate of 1,591,738 ADSs (the “New Warrant Shares”), at an exercise price of $5.00 per ADS. The Company expects to receive aggregate gross proceeds of approximately $4.0 million from the exercise of the Existing Warrants by the Holder, before deducting placement agent fees and other offering expenses payable by the Company.

The Company has engaged H.C. Wainwright & Co., LLC (the “Placement Agent”) to act as its exclusive placement agent in connection with the transactions contemplated by the Inducement Letter and has agreed to pay the Placement Agent a cash fee equal to 7.0% of the aggregate gross proceeds received from the Holder’s exercise of the Existing Warrants, as well as a management fee equal to 1.0% of the gross proceeds from the exercise of the Existing Warrants. The Company has also agreed to issue to the Placement Agent or its designees warrants (the “Placement Agent Warrants”) to purchase up to 55,711 ADSs (representing 7.0% of the Existing Warrants being exercised) which will have the same terms as the New Warrants except that the Placement Agent Warrants will have an exercise price equal to $6.25 per ADS (125% of the reduced exercise price of the Existing Warrants). Similar to the New Warrants, the Placement Agent Warrants will be immediately exercisable from the date of issuance until the two year anniversary of the effective date of the Resale Registration Statement (as defined below). In addition, the Company has also agreed to pay the Placement Agent $75,000 for non-accountable expenses and other out-of-pocket expenses and $15,950 for clearing fees.

The closing of the transactions contemplated pursuant to the Inducement Letter is expected to occur on or about March 5, 2026 (the “Closing Date”), subject to satisfaction of customary closing conditions. The Company expects to use the net proceeds from these transactions for funding research and development and clinical trials and for other working capital and general corporate purposes.

The ADSs representing the Company’s ordinary shares underlying the Existing Warrants have been registered pursuant to an existing registration statement on Form F-1 (File No. 333-288890), declared effective by the Securities and Exchange Commission (the “SEC”) on July 28, 2025.

The Company also agreed to file a registration statement on Form F-3 (or other appropriate form if the Company is not then Form F-3 eligible) providing for the resale of the New Warrant Shares representing the Company’s ordinary shares issued or issuable upon the exercise of the New Warrants (the “Resale Registration Statement”), as soon as practicable after the Closing Date, and to use commercially reasonable efforts to have such Resale Registration Statement declared effective by the SEC within 90 days following the date of the Inducement Letter and to keep the Resale Registration Statement effective at all times until no holder of the New Warrants owns any New Warrants or New Warrant Shares. In the Inducement Letter, the Company agreed not to issue any ADSs, ordinary shares or ordinary share equivalents or to file any other registration statement with the SEC (in each case, subject to certain exceptions) until 30 days after the effective date of the Resale Registration Statement. The Company also agreed not to effect or agree to effect any Variable Rate Transaction (as defined in the Inducement Letter) until one (1) year after the Closing Date (subject to an exception).

The New Warrants, Placement Agent Warrants, the New Warrant Shares and the ADSs issuable upon the exercise of the Placement Agent Warrants are being offered and sold pursuant to an exemption from the registration requirements under Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”). The Holder has represented that it is an accredited investor as defined in Rule 501 of the Securities Act and has acquired such securities for their own account and has no arrangements or understandings for any distribution thereof. The offer and sale of the foregoing securities is being made without any form of general solicitation or advertising. The New Warrants, Placement Agent Warrants, the New Warrant Shares and the ADSs issuable upon the exercise of the Placement Agent Warrants have not been registered under the Securities Act or applicable state securities laws. Accordingly, such securities may not be offered or sold in the United States except pursuant to an effective registration statement or an applicable exemption from the registration requirements of the Securities Act and such applicable state securities laws.

This Report on Form 6-K shall not constitute an offer to sell or the solicitation to buy nor shall there be any sale of the securities in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction.

Terms of the New Warrants

The following summary of certain terms and provisions of the New Warrants is not complete and is subject to, and qualified in its entirety by, the provisions of the New Warrants, the form of which is filed as Exhibit 10.2 to this Report on Form 6-K and is incorporated herein by reference. The following description of the New Warrants is qualified in its entirety by reference to such exhibit.

Duration and Exercise Price

Each New Warrant will have an exercise price equal to $5.00 per ADS. The New Warrants will be immediately exercisable from the date of issuance until the two year anniversary of the effective date of the Resale Registration Statement. The exercise price and number of New Warrant Shares issuable upon exercise of the New Warrants is subject to appropriate adjustment in the event of stock dividends, stock splits, subsequent rights offerings, pro rata distributions, reorganizations, or similar events affecting our ADSs or ordinary shares and the exercise price.

Exercisability

The New Warrants will be exercisable, at the option of each holder, in whole or in part, by delivering to us a duly executed exercise notice accompanied by payment in full for the number of ADSs purchased upon such exercise (except in the case of a cashless exercise as discussed below). A holder (together with its affiliates) may not exercise any portion of such holder’s New Warrants to the extent that the holder would own more than 4.99% (or, at the election of the holder, 9.99%) of our outstanding ordinary shares (including ADSs representing ordinary shares) immediately after exercise, except that upon prior notice from the holder to us, the holder may increase or decrease the amount of ownership of outstanding ordinary shares (including ADSs representing ordinary shares) after exercising the holder’s New Warrants up to 9.99% of the number of our ordinary shares (including ADSs representing ordinary shares) outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the New Warrants, provided that any increase will not be effective until 61 days following notice to us.

Cashless Exercise

If, at the time a holder exercises its New Warrants, a registration statement registering the resale of the New Warrant Shares by the holder under the Securities Act is not then effective or available, then in lieu of making the cash payment otherwise contemplated to be made to us upon such exercise in payment of the aggregate exercise price, the holder may elect instead to receive upon such exercise (either in whole or in part), the net number of ADSs determined according to a formula set forth in the New Warrants.

Trading Market

There is no established trading market for the New Warrants, and the Company does not expect an active trading market to develop. The Company does not intend to apply to list the New Warrants on any securities exchange or other trading market. Without a trading market, the liquidity of the New Warrants will be extremely limited.

Rights as a Shareholder

Except as otherwise provided in the New Warrants or by virtue of the holder’s ownership of our ADSs, such holder of New Warrants does not have the rights or privileges of a holder of our ADSs or ordinary shares, including any voting rights, until such holder exercises such holder’s New Warrants. The New Warrants will provide that the holders of the New Warrants have the right to participate in distributions or dividends paid on our ADSs or ordinary shares.

Fundamental Transactions

If at any time the New Warrants are outstanding, the Company, either directly or indirectly, in one or more related transactions effects a Fundamental Transaction (as defined in the New Warrant), a holder of New Warrants will be entitled to receive, upon exercise of the New Warrants, the kind and amount of securities, cash or other property that such holder would have received had they exercised the New Warrants immediately prior to the Fundamental Transaction. As an alternative, and at the holder’s option in the event of a Fundamental Transaction, exercisable at any time concurrently with, or within 30 days after, the consummation of the Fundamental Transaction (or, if later, the date of the public announcement of the applicable Fundamental transaction), the Company shall purchase the unexercised portion of the New Warrant from the holder by paying to the holder an amount of cash equal to the Black Scholes Value (as defined in the New Warrant) of the remaining unexercised portion of the New Warrant on the date of the consummation of such Fundamental Transaction.

Waivers and Amendments

The New Warrants may be modified or amended or the provisions of the New Warrants waived with ours and the holder’s written consent.

The forms of Inducement Letter, New Warrants and Placement Agent Warrants are attached as Exhibits 10.1, 10.2 and 10.3, respectively. The description of the terms of the Inducement Letter, the New Warrants and the Placement Agent Warrants are not intended to be complete and are qualified in its entirety by reference to such exhibits. The Inducement Letter contains customary representations, warranties and covenants by us which were made only for the purposes of such agreements and as of specific dates, were solely for the benefit of the parties to such agreements and may be subject to limitations agreed upon by the contracting parties.
