Explanatory Note

This registration statement relates to, and shall act, upon effectiveness, as Post-Effective Amendment No. 1 on Form F-1 to the Registration Statement on Form F-1 (File No. 333-290437) (the “Prior Registration Statement”), containing an updated prospectus with respect to the resale by the selling shareholder named therein (the “Selling Shareholder”) of up to 439,942 American Depositary Shares (“ADSs”) of Scinai Immunotherapeutics Ltd. (“Scinai,” “we,” “us” or the “Company”) issuable under that certain Standby Equity Purchase Agreement dated September 10, 2025, by and between the Company and the Selling Shareholder. Each ADS represents 40,000 ordinary shares, no par value, of the Company.

The information included in this filing updates the Prior Registration Statement and the prospectus contained therein. In addition, effective August 21, 2026, we effected a ratio change of the American Depositary Shares (ADSs) to our ordinary shares from the previous ratio of one (1) ADS representing four thousand (4,000) non-traded ordinary shares to a new ratio of one (1) ADS representing forty thousand (40,000) ordinary shares. Such ratio change had the same effect as a one-for-ten reverse ADS split. Unless otherwise indicated, ADSs and per ADS amounts in the Prior Registration Statement have been retroactively adjusted to reflect the changes in ratio for all periods presented.  

No additional securities covered by the Registration Statement are being registered in this registration statement. All filing fees payable in connection with the registration of the securities covered by the Prior Registration Statement were paid at the time of the original filing of the Prior Registration Statement.

The information in this preliminary prospectus is not complete and may be changed. We may not sell these securities until the registration statement filed with the Securities and Exchange Commission is effective. This preliminary prospectus is not an offer to sell these securities and we are not soliciting an offer to buy these securities in any jurisdiction where the offer or sale is not permitted.

Subject to completion, dated August 27, 2026.

PRELIMINARY PROSPECTUS

439,942 American Depositary Shares representing 17,597,680,000 Ordinary Shares

Scinai Immunotherapeutics Ltd. 

This prospectus relates to the offer and sale of up to 439,942 American Depositary Shares (“ADSs”), by YA II PN, Ltd., or YA or the Selling Shareholder, a Cayman Islands limited partnership. Each ADS represents 40,000 of our ordinary shares, no par value (“Ordinary Shares”).

The Ordinary Shares represented by ADSs being offered by the Selling Shareholder are to be issued pursuant to the Standby Equity Purchase Agreement dated September 10, 2025 that we entered into with YA, or the Purchase Agreement. We are not selling any securities under this prospectus and will not receive any of the proceeds from the sale of ADSs by the Selling Shareholder. However, we may receive up to $15.0 million in aggregate gross proceeds from sales of ADSs to YA that we may make under the Purchase Agreement from time to time during the 36 months following the execution of the Purchase Agreement, or the Advance Shares. Pursuant to the Purchase Agreement, we issued an aggregate of 3,546 ADSs to YA upon execution of the Purchase Agreement as consideration for its irrevocable commitment to purchase ADSs under the Purchase Agreement, or the Commitment Shares, and to date, we have issued to YA an aggregate of 36,512 Advance Shares for aggregate gross proceeds of approximately $100 thousand, and YA has sold all such Advance Shares. The remaining 439,942 ADSs representing Advance Shares that may be offered pursuant to this prospectus would be purchased by YA from time to time pursuant to the Purchase Agreement at a price equal to 97% of the lowest of the three daily volume weighted average prices, or VWAPs, during a pricing period as set forth in the Purchase Agreement and would be subject to certain limitations.

The Selling Shareholder may sell the ADSs included in this prospectus in a number of different ways and at varying prices. We provide more information about how the Selling Shareholder may sell the shares in the section entitled “Plan of Distribution.” The Selling Shareholder is an “underwriter” within the meaning of Section 2(a)(11) of the Securities Act of 1933, as amended.

The Selling Shareholder will pay all brokerage fees and commissions and similar expenses in connection with the offer and sale of the shares by the Selling Shareholder pursuant to this prospectus. We will pay the expenses (except brokerage fees and commissions and similar expenses) incurred in registering under the Securities Act the offer and sale of the shares included in this prospectus by the Selling Shareholder. See “Plan of Distribution.”

The ADSs are listed on the Nasdaq Capital Market, or Nasdaq, under the symbol “SCNI.” On August 26, 2026, the last reported sale price of the ADSs on Nasdaq was $2.87 per ADS.

We are a “foreign private issuer,” as defined under the U.S. federal securities laws and are subject to reduced public company reporting requirements. See “Prospectus Summary – Implications of Being a Foreign Private Issuer” for additional information.

Investing in our securities involves a high degree of risk. See the section entitled “Risk Factors” appearing on page 6 of this prospectus and elsewhere in this prospectus and the accompanying base prospectus for a discussion of information that should be considered in connection with an investment in our securities.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or passed upon the adequacy or accuracy of this prospectus. Any representation to the contrary is a criminal offense.

The date of this prospectus is               , 2026.

In this prospectus, unless the context otherwise requires,

Market, Industry and Other Data

This prospectus includes or incorporates by reference estimates, projections and other information concerning our industry, our business, and the markets for our product candidates. Information that is based on estimates, forecasts, projections, market research or similar methodologies is inherently subject to uncertainties, and actual events or circumstances may differ materially from events and circumstances that are assumed in this information. Unless otherwise expressly stated, we obtained this industry, business, market and other data from our own internal estimates and research as well as from reports, research surveys, studies and similar data prepared by market research firms and other third parties, industry, medical and general publications, government data and similar sources.

In addition, assumptions and estimates of our and our industry’s future performance are necessarily subject to a high degree of uncertainty and risk due to a variety of factors, including those described in “Risk Factors” in and incorporated into this prospectus. These and other factors could cause our future performance to differ materially from our assumptions and estimates. See “Cautionary Note Regarding Forward-Looking Statements.”

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus, including the information incorporated by reference into this prospectus, contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These statements involve known and unknown risks, uncertainties and other factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. In some cases, you can identify forward-looking statements by terms including “anticipates,” “believes,” “could,” “estimates,” “expects,” “intends,” “may,” “plans,” “potential,” “predicts,” “projects,” “should,” “will,” “would,” and similar expressions intended to identify forward-looking statements, but these are not the only ways these statements are identified. Forward-looking statements reflect our current views with respect to future events and are based on assumptions and subject to risks and uncertainties. You should not put undue reliance on any forward-looking statements. Unless we are required to do so under U.S. federal securities laws or other applicable laws, we do not intend to update or revise any forward-looking statements. Readers are encouraged to consult the Company’s filings made on Form 6-K, which are periodically filed with or furnished to the SEC.

The following is a summary of some of the principal risks we face. The list below is not exhaustive, and investors should read the “Risk Factors” section and “Item 3. Key Information - Risk Factors” in our Annual Report on Form 20-F for the year-ended December 31, 2025, in full. 

the risk of disruptions to our manufacturing facilities or operations, which could adversely affect our ability to develop product candidates or deliver CDMO services.

Risk Factors

An investment in our securities involves a high degree of risk. Our business, financial condition, or results of operations could be adversely affected by any of these risks. Before making an investment in our securities, you should carefully consider all of the information included in this prospectus, including the risks described below. The risks and uncertainties we have described below and in our 2025 Annual Report are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our operations. If any of these risks actually occur, our business, business prospects, financial condition, or results of operations could be seriously harmed. This could cause the trading price of the ADSs to decline, resulting in a loss of all or part of your investment. Please also read carefully the section above entitled “Cautionary Note Regarding Forward-Looking Statements.”

Risks Related to the Offering

It is not possible to predict the actual number of shares we will sell under the Purchase Agreement to the Selling Shareholder, or the actual gross proceeds resulting from those sales.

Pursuant to the Purchase Agreement, YA has committed to purchase up to $14.9 million in ADSs, subject to certain limitations and conditions set forth in the Purchase Agreement. The ADSs that may be issued under the Purchase Agreement may be sold by us to YA at our discretion from time to time during the Commitment Period.

We generally have the right to control the timing and amount of sales of the ADSs to YA under the Purchase Agreement. Sales of ADSs, if any, to YA under the Purchase Agreement will depend upon market conditions and other factors. We may ultimately decide to sell to YA all, some or none of the ADSs that may be available for us to sell to YA pursuant to the Purchase Agreement.

Because the purchase price per share to be paid by YA for the ADSs that we may elect to sell to YA under the Purchase Agreement, if any, will fluctuate based on the market prices of the ADSs during the applicable Pricing Period for each purchase made pursuant to the Purchase Agreement, if any, it is not possible for us to predict, as of the date of this prospectus and prior to any such sales, the number of ADSs that we will sell to YA under the Purchase Agreement, the purchase price per share that YA will pay for shares purchased from us under the Purchase Agreement, or the aggregate gross proceeds that we will receive from those purchases by YA under the Purchase Agreement, if any.

Limitations in the Purchase Agreement, including the Ownership Limitation, and our ability to meet the conditions necessary to deliver an Advance Notice, could prevent us from being able to raise funds up to the Commitment Amount.

Moreover, 439,942 ADSs are being registered for resale by YA under the registration statement that includes this prospectus, consisting of the Advance Shares that we may elect to sell to YA, in our sole discretion, from time to time during the Commitment Period, subject to the restrictions and satisfaction of the conditions in the Purchase Agreement, through sales under the Purchase Agreement. Even if we elect to sell to YA all of the shares being registered for resale under this prospectus, depending on the market prices of the ADSs at the time of such sales, the actual gross proceeds from the sale of all such shares may be substantially less than the approximately $14.9 million total remaining commitment of YA under the Purchase Agreement, which could materially adversely affect our liquidity.

If we desire to issue and sell to YA under the Purchase Agreement a number of ADSs in excess of the YA Shares being registered for resale under this prospectus, and the Ownership Limitation and other limitations in the Purchase Agreement would allow us to do so, we would need to file with the SEC one or more additional registration statements to register under the Securities Act the resale by YA of any such additional ADSs, and the SEC would have to declare such registration statement or statements effective before we could sell additional ADSs.

Any issuance and sale by us of a substantial amount of ADSs under the Purchase Agreement in addition to the ADSs being registered for resale by YA under this prospectus could cause additional substantial dilution to our shareholders. The number of our ADSs ultimately offered for sale by YA is dependent upon the ADSs, if any, we ultimately sell to YA under the Purchase Agreement.

The resale by YA of a significant number of shares registered for resale in this offering at any given time, or the perception that these sales may occur, could cause the market price of the ADSs to decline and to be highly volatile.

We will have broad discretion in how to use the net proceeds of this offering, and we may not use these proceeds in a manner currently contemplated.

We will have broad discretion as to the use of the net proceeds from this offering and could use them for purposes other than those contemplated at the time of this offering. Accordingly, you will be relying on the judgment of our management with regard to the use of these net proceeds, and you will not have the opportunity as part of your investment decision to assess whether the proceeds are being used consistently with current expectations. Our needs may change as the business and the industry that we address evolves. As a result, the proceeds to be received in this offering may be used in a manner significantly different from our current expectations. It is possible that the proceeds will be invested in a way that does not yield a favorable, or any, return. The failure of our management to use such funds effectively could have a material adverse effect on our business, financial condition, operating results and cash flow.

The sale of a substantial amount of ADSs, including resale of the ADSs held by the selling shareholder in the public market, could adversely affect the prevailing market price of the ADSs and could impair our ability to raise capital through the sale of additional equity securities. We are unable to predict the effect that sales may have on the prevailing market price of the ADSs.

We are registering for resale 439,942 ADSs that we may issue to YA from time to time pursuant to the Purchase Agreement. Sales of substantial amounts of ADSs in the public market, or the perception that such sales might occur, could adversely affect the market price of the ADSs and could impair our ability to raise capital through the sale of additional equity securities. We cannot predict if and when YA may sell such shares in the public markets. Furthermore, in the future, we may issue additional ADSs or other equity or debt securities convertible into ADSs.

Future sales of the ADSs, including any ADSs issuable upon the exercise of the warrants to acquire ADSs or the conversion of preferred shares issued to the European Investment Bank , or the EIB, or the perception that future sales may occur, may cause the market price of the ADSs to decline, even if our business is doing well.

To raise capital, we may sell ADSs, convertible securities or other equity securities in one or more transactions other than those contemplated by the Purchase Agreement, at prices and in a manner we determine from time to time. Sales by us or sales by the ADS holders of a substantial number of ADSs in the public market could occur in the future. These sales, or the perception in the market that we or the holders of a large number of ADSs intend to sell shares, may cause the market price of the ADSs to decline. In addition, to the extent that holders of warrants to purchase ADSs sell the ADSs issued upon the exercise of their warrants to purchase ADSs or holders of the preferred shares sell the ADSs issued upon the conversion of the preferred shares, the market price of the ADSs may decrease due to the additional selling pressure in the market. The risk of dilution from issuances of ADSs underlying the warrants to purchase ADSs may cause shareholders to sell their ADSs, which could cause a further decline in the market price.

Risks Related to our Securities

Our failure to meet the continued listing requirements of Nasdaq could result in a delisting of the ADSs. The delisting could adversely affect the market liquidity of our shares and the market price of our shares could decrease significantly.

If we fail to satisfy Nasdaq’s continued listing requirements, Nasdaq may take steps to delist the ADSs.

On March 12, 2026, we received a notice of non-compliance from Nasdaq that we are not in compliance with the requirement to maintain a minimum bid price of $1.00 per share as required by Nasdaq Listing Rule 5550(a)(2) (the “Minimum Price Rule”). We were given 180 days, or until September 8, 2026, to regain compliance. To regain compliance, effective August 21, 2026, we effected a ratio change of the American Depositary Shares (ADSs) to our ordinary shares from the previous ratio of one (1) ADS representing four thousand (4,000) non-traded ordinary shares to a new ratio of one (1) ADS representing forty thousand (40,000) ordinary shares. Such ratio change had the same effect as a one-for-ten reverse ADS split. There can be no assurance that this ratio change will enable us to regain or maintain compliance with Nasdaq’s continued-listing requirements

Similarly, on November 1, 2023, we received a notice of non-compliance from Nasdaq that we are not in compliance with the Minimum Price Rule, and on April 30, 2024, we received a staff determination letter from Nasdaq notifying us that, due to our continued non-compliance with the Minimum Price Rule, the ADSs would be scheduled for delisting from Nasdaq and suspended for trading4 unless we timely request a hearing before an independent Nasdaq Hearings Panel (the “Hearing Panel”). We appealed this determination and requested a hearing before the Hearing Panel, which stayed the suspension. Our board of directors also approved a ratio change of the ADSs to our non-traded Ordinary Shares, increasing the number of Ordinary Shares represented by each ADS from 400 to 4,000, which was equivalent to a reverse split of 1 for 10. This action resulted in our compliance with the Minimum Price Rule.

In addition, we received notification letters from Nasdaq dated September 28, 2022 and May 1, 2023 advising us that we are not in compliance with Listing Rule 5550(b)(1) requiring companies listed on Nasdaq to maintain a minimum of $2,500,000 in stockholders’ equity (the “Minimum Stockholders’ Equity Rule”) for continued listing. On November 20, 2023, we announced the receipt of formal notification from Nasdaq that we had regained compliance with the Minimum Stockholders’ Equity Rule. Nasdaq also indicated that if we do not evidence such compliance in our next periodic report (the Annual Report on Form 20-F), Nasdaq may provide notification to us that the ADSs may be subject to delisting, at which time we may appeal the determination to a Hearings Panel. Our shareholders’ equity as of December 31, 2023, as reflected in our financial statements for the year ended December 31, 2023, was less than the minimum of $2,500,000 in stockholders’ equity required by Nasdaq for continued listing.

As a result, on May 20, 2024, we received a staff determination letter from the Staff of Nasdaq that we are not in compliance with the Minimum Stockholders’ Equity Rule. On June 18, 2024, a hearing was held before an independent Nasdaq Hearings Panel (the “Hearings Panel”), and we presented our views with respect to the stockholders’ equity deficiency, including presenting a plan to address the Equity Requirement matter by converting a significant portion of the loan owed by us to the EIB (EUR 26.6 million (equal to approximately $29 million), including interest accrued to date) into equity.

On August 29, 2024, following completion of the conversion of a significant portion of the loan owed by us to the EIB into preferred shares, we announced that we had received formal notification from the Staff that we have regained compliance with the Equity Requirement.

In addition, on January 13, 2026, Nasdaq filed a proposed rule change with the SEC which would provide that a listed company’s securities will be subject to immediate suspension and delisting if it has failed to maintain a value of at least $5 million in Market Value of Listed Securities (as defined in the Nasdaq rules) (“MVLS”) of its securities for a period of 30 consecutive business days, which is an additional ground for immediate suspension and delisting. The SEC approved the proposed rule change on July 22, 2026. Although implementation of this rule was stayed by the SEC on July 29, 2026 pending further SEC review, there can be no assurance that the rule will not become effective in its current form. The MVLS of our ADSs is currently below the $5 million threshold.

If the proposed rule becomes enforceable upon the lifting of the SEC stay, and the MVLS of our ADSs is not above $5.0 million for a period of 30 consecutive business days, the trading in the ADSs would immediately be suspended and be delisted, with no cure period or appeal available except to challenge errors in the initial suspension determination or our ability to demonstrate compliance with all initial (rather than continued) listing standards across our equity tiers, which are generally more stringent than the continued listing standards from which we fell out of compliance. The enforceability of this new requirement could materially increase the risk of immediate suspension and delisting of the ADSs, which would likely have a material adverse effect on our and the market price of the ADSs and our ability to raise additional capital

If the ADSs are delisted from Nasdaq, trading of our securities would most likely take place in an over-the-counter market (“OTC”) for unlisted securities. OTC trading generally involves significantly reduced liquidity, wider bid-ask spreads, decreased investor coverage, and heightened price volatility. An investor would likely find it less convenient to sell, or to obtain accurate quotations in seeking to buy, our securities in an over-the-counter market, and many investors would likely not buy or sell our securities due to difficulty in accessing over-the-counter markets, policies preventing them from trading in securities not listed on a national exchange or other reasons. In addition, as a delisted security, our securities would be subject to SEC rules as a “penny stock,” which impose additional disclosure requirements on broker-dealers. The regulations relating to penny stocks, coupled with the typically higher cost per trade to the investor of penny stocks due to factors such as broker commissions generally representing a higher percentage of the price of a penny stock than of a higher-priced stock, would further limit the ability of investors to trade in our securities. For these reasons and others, delisting would adversely affect the liquidity, trading volume and price of our securities, causing the value of an investment in us to decrease and having an adverse effect on our business, financial condition, and results of operations, including our ability to attract and retain qualified employees and raise capital.

A delisting from Nasdaq would likely have a negative effect on the price of the ADSs and would impair shareholders’ ability to sell or purchase their ADSs when they wish to do so. In the event of a delisting, we can provide no assurance that any action taken by us to restore compliance with listing requirements would allow the ADSs to become listed again, stabilize the market price or improve the liquidity of the ADSs, prevent the ADSs from dropping below the Nasdaq minimum bid price requirement or prevent future non-compliance with Nasdaq’s listing requirements.

Use of Proceeds

This prospectus relates to ADSs that may be offered and sold from time to time by YA. All of the ADSs offered by the Selling Shareholder pursuant to this prospectus will be sold by the Selling Shareholder for its own account. We will not receive any of the proceeds from these sales.

We may receive up to approximately $14.9 million in aggregate gross proceeds under the Purchase Agreement from any sales of ADSs we make to YA pursuant to the Purchase Agreement. However, we are unable to estimate the actual amount of proceeds that we may receive, as it will depend on the number of ADSs that we choose to sell, our ability to meet the conditions to purchases set forth in the Purchase Agreement, market conditions and the price of the ADSs, among other factors.

We currently intend to use the net proceeds from YA pursuant to the Purchase Agreement, if any, for the continued development of our pipeline of innovative drug candidates, support of our CDMO business as well as general corporate purposes, which may include working capital, research and development activities, regulatory matters, capital investment or other related purposes. Although we have identified some potential uses of the net proceeds to be received from YA, we cannot specify these uses with certainty. Our management will have broad discretion in the application of the net proceeds and could use them for purposes other than those contemplated as of the date of this prospectus. Our shareholders may not agree with the manner in which our management chooses to allocate and spend the net proceeds. Moreover, our management may use the net proceeds for corporate purposes that may not result in our being profitable or increasing our market value.

Our expected use of net proceeds under the Purchase Agreement represents our current intentions based on our present plans and business conditions, which could change in the future as our plans and business conditions evolve. As of the date of this prospectus, we cannot predict with certainty any or all of the particular uses of the net proceeds to be received under the Purchase Agreement, or the amounts, if any, that we will actually spend on the uses set forth above. The amounts and timing of our actual use of the net proceeds may vary depending on numerous factors, including our ability to obtain additional financing and changes we may make to our development plan. As a result, our management will have broad discretion in the application of the net proceeds, which may include uses not set forth above, and investors will rely on our judgment regarding the application of the net proceeds from this offering.

Pending the use of the net proceeds from sales of ADSs by us pursuant to the Purchase Agreement as described above, we intend to invest the net proceeds in a variety of capital preservation investments, short and intermediate term, interest-bearing, investment-grade instruments, U.S. government securities and highly rated corporate debt securities, although our investment policy may change following the date of this prospectus supplement. It is possible that, pending their use, we may invest the net proceeds in a way that does not yield a favorable, or any, return for us.

Capitalization

The following table sets forth our total capitalization:

The pro forma as adjusted information set forth below is illustrative only and will be adjusted based on the actual public offering price and number of ADSs sold under the Purchase Agreement. You should read this information together with our consolidated financial statements.

The information included in the table below is unaudited. The information set forth in the following table should be read in conjunction with and is qualified in its entirety by reference to the unaudited and audited financial statements and notes thereto that are incorporated by reference into this prospectus and the other financial information included or incorporated by reference into this prospectus.

The number of ADSs to be outstanding immediately after the offering, as shown above, is based on 706,586 ADSs (representing 28,263,440,000 Ordinary Shares) outstanding as of August 23, 2026 and does not include, as of such date:

Unless otherwise stated, all information in this prospectus assumes no exercise of the outstanding options or warrants into ADSs and no conversion of preferred shares into ADSs as described above.

SELLING SHAREHOLDER

This prospectus relates to the possible resale from time to time by YA of any or all of the ADSs that are to be issued by us to YA under the Purchase Agreement. For additional information regarding the issuance of Ordinary Shares covered by this prospectus, see the section titled “Prospectus Summary—Standby Equity Purchase Agreement with YA” above. Except for the transactions contemplated by the Purchase Agreement and the March 2025 Purchase Agreement described above, YA does not, and has not had, any material relationship with us.

The table below presents information regarding the Selling Shareholder and the ADSs that it may offer from time to time under this prospectus. This table is prepared based on information supplied to us by the Selling Shareholder. The number of ADSs in the column “Maximum Number of ADSs to be Offered Pursuant to this Prospectus” represents all of the ADSs that the Selling Shareholder may offer under this prospectus. The Selling Shareholder may sell some, all or none of its ADSs in this offering. We do not know how long the Selling Shareholder will hold the shares before selling them, and we currently have no agreements, arrangements or understandings with the Selling Shareholder regarding the sale of any of the shares.

The beneficial ownership of our ADSs is determined in accordance with the rules of the SEC.

The percentage of ADSs beneficially owned by the Selling Shareholder prior to the offering shown in the table below is based on an aggregate of 706,586 ADSs outstanding on August 23, 2026. The number of ADSs that may actually be sold by us under the Purchase Agreement may be fewer than the number of ADSs being offered by this prospectus. The fourth column assumes the sale of all of the ADSs offered by the Selling Shareholder pursuant to this prospectus.

Our authorized share capital consists of (i) 1,600,000,000,000 Ordinary Shares, no par value, the equivalent of 40 million ADSs (each ADS representing 40,000 Ordinary Shares) and (ii) 1,000 preferred shares, no par value per share. As of August 23, 2026, there were 28,263,440,000 Ordinary Shares issued and outstanding (all of which were represented by ADSs). All of our outstanding Ordinary Shares are validly issued, fully paid and non-assessable. Our Ordinary Shares are not redeemable and do not have any preemptive rights.

Voting Rights

Holders of our Ordinary Shares have one vote for each Ordinary Share held on all matters submitted to a vote of shareholders at a shareholder meeting. Shareholders may vote at shareholder meetings either in person, by proxy or by written ballot. Israeli law does not allow public companies to adopt shareholder resolutions by means of written consent in lieu of a shareholder meeting. According to the Companies Law and the regulations promulgated thereunder, for purposes of determining the shareholders entitled to notice and to vote at such meeting, the board of directors may fix the record date not more than 60 nor less than four calendar days prior to the date of the meeting, provided that an announcement regarding the general meeting be given prior to the record date. Unless stipulated differently in the Companies Law or in the Articles of Association, all shareholders’ resolutions shall be approved by a simple majority vote. Except as otherwise disclosed herein, an amendment to our Articles of Association requires the prior approval of the holders of at least 75% of our Ordinary Shares, represented and voting at a general meeting.

Our Ordinary Shares do not have cumulative voting rights for the election of directors. As a result, the holders of a majority of the voting power represented at a shareholders meeting have the power to elect all of our directors, subject to the special approval requirements for external directors under the Israeli Companies Law.

Transfer of Shares

Our Ordinary Shares that are fully paid for are issued in registered form and may be freely transferred under our Articles of Association, unless the transfer is restricted or prohibited by applicable law or the rules of a stock exchange on which the shares are traded. The ownership or voting of our Ordinary Shares by non-residents of Israel is not restricted in any way by our Articles of Association or Israeli law, except for ownership by nationals of some countries that are, or have been, in a state of war with Israel.

The Powers of the Directors

Our board of directors shall direct the Company’s policy and shall supervise the performance of the Company’s Chief Executive Officer. Pursuant to the Companies Law and our articles of association, our board of directors may exercise all powers and take all actions that are not required under law or our articles of association to be exercised or taken by our shareholders, including the power to borrow money for Company purposes.

Amendment of share capital

Our articles of association enable us to increase or reduce our share capital. Any such changes are subject to the provisions of the Companies Law and must be approved by a resolution duly passed by our shareholders at a general or special meeting by voting on such change in the capital. In addition, transactions that have the effect of reducing capital, such as the declaration and payment of dividends in the absence of sufficient retained earnings and profits and an issuance of shares for less than their nominal value, require a resolution of our board of directors and court approval.

Dividends

Under Israeli law, we may declare and pay dividends only if, upon the determination of our board of directors, there is no reasonable concern that the distribution will prevent us from being able to meet the terms of our existing and foreseeable obligations as they become due. Under the Companies Law, the distribution amount is further limited to the greater of retained earnings or earnings generated over the two most recent years legally available for distribution according to our then last reviewed or audited financial statements, provided that the date of the financial statements is not more than six months prior to the date of distribution. In the event that we do not have retained earnings or earnings generated over the two most recent years legally available for distribution, we may seek the approval of the court in order to distribute a dividend. The court may approve our request if it is determined that there is no reasonable concern that the payment of a dividend will prevent us from satisfying our existing and foreseeable obligations as they become due. In addition, no dividends may be paid on our ordinary shares until all of our preferred shares have been fully redeemed.

Shareholder Meetings

Under Israeli law, we are required to hold an annual general meeting of our shareholders once every calendar year and in any event no later than 15 months after the date of the previous annual general meeting. All meetings other than the annual general meeting of shareholders are referred to as special meetings. Our board of directors may call special meetings whenever it sees fit, at such time and place, within or outside of Israel, as it may determine. In addition, as a company whose shares are listed for trade on an exchange outside of Israel, the Companies Law provides that our board of directors is required to convene a special meeting upon the written request of (i) any two of our directors or one quarter of the directors then in office; or (ii) one or more shareholders holding, in the aggregate either (a) 10% of our issued share capital and 1% of our outstanding voting power, or (b) 10% of our outstanding voting power.

Under Israeli law, one or more shareholders holding at least 1% of the voting rights at the general meeting may request that the board of directors include a matter in the agenda of a general meeting to be convened in the future (or, with respect to a company whose shares are listed for trade on an exchange outside of Israel, such as us, 5% if the matter is the appointment or removal of a director), provided that it is appropriate to discuss such any other matter at the general meeting

Subject to the provisions of the Companies Law and the regulations promulgated thereunder, shareholders entitled to participate and vote at general meetings are the shareholders of record on a date to be decided by the board of directors. Furthermore, the Companies Law and our articles of association require that resolutions regarding the following matters must be passed at a general meeting of our shareholders:

The Companies Law requires that a notice of any annual or special shareholders meeting be provided at least 21 days prior to the meeting and if the agenda of the meeting includes the appointment or removal of directors, the approval of transactions with office holders or interested or related parties, or an approval of a merger, notice must be provided at least 35 days prior to the meeting.

Quorum

The quorum required for our general meetings of shareholders consists of one or more shareholders present in person, by proxy or by other voting instrument in accordance with the Companies Law who hold or represent, in the aggregate, at least 10% (or, for so long we do not qualify as a foreign private issuer and for only so long as required by the Nasdaq Stock Market, 33 1/3% of the Company’s outstanding Ordinary Shares) of the total outstanding voting rights, within half an hour from the appointed time.

A meeting adjourned for lack of a quorum is adjourned to the same day in the following week at the same time and place or to a later date if so specified in the summons or notice of the meeting. At the reconvened meeting, any number of our shareholders present in person or by proxy shall constitute a lawful quorum.

Resolutions

Our articles of association provide that all resolutions of our shareholders require a simple majority vote, unless otherwise required by applicable law or by another provision of the articles of association.

Israeli law provides that a shareholder of a public company may vote in a meeting and in a class meeting by means of a written ballot in which the shareholder indicates how he or she votes on resolutions relating to the following matters:

The provision allowing the vote by written ballot does not apply where the voting power of the controlling shareholder is sufficient to determine the vote.

The Companies Law provides that a shareholder, in exercising his or her rights and performing his or her obligations toward the company and its other shareholders, must act in good faith and in a customary manner, and avoid abusing his or her power. This is required when voting at general meetings on matters such as changes to the articles of association, increasing the company’s registered capital, mergers and approval of certain interested or related party transactions. A shareholder also has a general duty to refrain from depriving any other shareholder of its rights as a shareholder. In addition, any controlling shareholder, any shareholder who knows that its vote can determine the outcome of a shareholder vote and any shareholder who, under such company’s articles of association, can appoint or prevent the appointment of an office holder or other power towards the company, is required to act with fairness towards the company. The Companies Law does not describe the substance of this duty except that the remedies generally available upon a breach of contract will also apply to a breach of the duty to act with fairness, and, to the best of our knowledge, there is no binding case law that addresses this subject directly.

Under the Companies Law, unless provided otherwise in a company’s articles of association, a resolution at a shareholders meeting requires approval by a simple majority of the voting rights represented at the meeting, in person, by proxy or written ballot, and voting on the resolution. Generally, a resolution for the voluntary winding up of the company requires the approval of holders of 75% of the voting rights represented at the meeting, in person, by proxy or by written ballot and voting on the resolution.

In the event of our liquidation, after satisfaction of liabilities to creditors, our assets will be distributed to the holders of our Ordinary Shares in proportion to their shareholdings. This right, as well as the right to receive dividends, may be affected by the grant of preferential dividend or distribution rights to the holders of a class of shares with preferential rights that may be authorized in the future.

Access to Corporate Records

Under the Companies Law, all shareholders of a company generally have the right to review minutes of the company’s general meetings, its shareholders register and principal shareholders register, articles of association, financial statements and any document it is required by law to file publicly with the Israeli Companies Registrar and the ISA. Any of our shareholders may request to review any document in our possession that relates to any action or transaction with a related party, interested party or office holder that requires shareholder approval under the Companies Law. We may deny a request to review a document if we determine that the request was not made in good faith, that the document contains a commercial secret or a patent or that the document’s disclosure may otherwise prejudice our interests. 

Acquisitions under Israeli Law

Full Tender Offer

A person wishing to acquire shares of a public Israeli company and who would as a result hold over 90% of the target company’s issued and outstanding share capital is required by the Companies Law to make a tender offer to all of the company’s shareholders who hold shares of the same class for the purchase of all of the issued and outstanding shares of the company. If the shareholders who do not accept the offer hold less than 5% of the issued and outstanding share capital of the company or of the applicable class, all of the shares that the acquirer offered to purchase will be transferred to the acquirer by operation of law (provided that a majority of the offerees that do not have a personal interest in such tender offer shall have approved the tender offer except that if the total votes to reject the tender offer represent less than 2% of the company’s issued and outstanding share capital, in the aggregate, approval by a majority of the offerees that do not have a personal interest in such tender offer is not required to complete the tender offer). However, a shareholder that had its shares so transferred may petition the court within six months from the date of acceptance of the full tender offer, whether or not such shareholder agreed to the tender or not, to determine whether the tender offer was for less than fair value and whether the fair value should be paid as determined by the court unless the acquirer stipulated in the tender offer that a shareholder that accepts the offer may not seek appraisal rights, so long as prior to the acceptance of the full tender offer, the acquirer and the company disclosed the information required by law in connection with the full tender offer. If the shareholders who did not accept the tender offer hold 5% 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 a public Israeli 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 25% or more of the voting rights in the company, unless one of the exemptions in the Companies Law is met. 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 tender offer if as a result of the acquisition the purchaser would become a holder of 45% or more of the voting rights in the company, if there is no other shareholder of the company who holds 45% or more of the voting rights in the company, unless one of the exemptions in the Companies Law is met.

A special tender offer must be extended to all shareholders of a company, but the offeror is not required to purchase shares representing more than 5% of the voting power attached to the company’s outstanding shares, regardless of how many shares are tendered by shareholders. A 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 number of shares tendered in the offer exceeds the number of shares whose holders objected to the offer.

If a special tender offer is accepted, then the purchaser or any person or entity controlling it or under common control with the purchaser or such controlling person or entity may not make a subsequent tender offer for the purchase of shares of the target company and may not enter into 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.

Under regulations enacted pursuant to the Companies Law, the above special tender offer requirements may not apply to companies whose shares are listed for trading on a foreign stock exchange if, among other things, the relevant foreign laws or the rules of the stock exchange, include provisions limiting the percentage of control which may be acquired or that the purchaser is required to make a tender offer to the public. However, the Israeli Securities Authority’s opinion is that such leniency does not apply with respect to companies whose shares are listed for trading on stock exchanges in the United States, including the NASDAQ Capital Market, which do not provide for sufficient legal restrictions on obtaining control or an obligation to make a tender offer to the public, therefore the special tender offer requirements shall apply to such companies.

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 shares voted on the proposed merger at a shareholders’ meeting called with at least 35 days’ prior notice.

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 or the exclusion of the votes of certain shareholders as provided above, a court may still approve 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 value of the parties to the merger and the consideration offered to the shareholders. 

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 any of the parties to the merger, and may further give instructions 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 by each party with the Israeli Registrar of Companies and 30 days have passed from the date the merger was approved by the shareholders of each party.

Antitakeover Measures

The Companies Law allows us to create and issue shares having rights different from those attached to our Ordinary Shares, including shares providing certain preferred rights, distributions or other matters and shares having preemptive rights. As of the date of this prospectus, we have authorized and issued ordinary shares and preferred shares. In the future, if we do create and issue a class of shares other than Ordinary Shares, such class of shares, depending on the specific rights that may be attached to them, may delay or prevent a takeover or otherwise prevent our shareholders from realizing a potential premium over the market value of their Ordinary Shares. The authorization of a new class of shares will require an amendment to our articles of association which requires the prior approval of the holders of at least 75% of our Ordinary Shares at a general meeting. Shareholders voting in such meeting will be subject to the restrictions provided in the Companies Law as described above.

Preferred Shares

Conversion Terms of Preferred Shares

On August 21, 2024, we announced that we had closed a Loan Restructuring Agreement (the “Restructuring Agreement”) with our lender, EIB, which included an amendment to the amended Finance Contract (the “Finance Contract”) between the parties (the transactions contemplated by the Restructuring Agreement called the “EIB Restructuring Transaction”).

In connection with the EIB Restructuring Transaction, an amount equal to approximately EUR 26.6 million (equal to approximately $31.35 million as of September 18, 2025), including interest accrued to date, owed by us to the EIB under the Finance Contract was converted into 1,000 of our preferred shares, no par value per share (“Preferred Shares”).

The Preferred Shares are convertible (in whole or in part), at the option of the EIB (the current holder of all), into 1,456,000,000 Ordinary Shares in the aggregate, which will then automatically be converted into ADSs, with each Preferred Share convertible into 1,456,000 Ordinary Shares (represented by ADSs). The number of ADSs that can be acquired upon conversion of the Preferred Shares is also subject to adjustment in the event of any share split, share dividend and similar events involving the Ordinary Shares.

Stated Redemption Value of the Preferred Shares

The Preferred Shares entitle the holders thereof to redemption payments in the aggregate amount of $34 million ($34,000 per Preferred Share). In the event a Preferred Share is converted into Ordinary Shares, the right to receive such payment for such Preferred Share will be extinguished. The Company will pay the redemption payment only if and at such time (i) as the Company elects, at its sole discretion, to make any such redemption payments, provided that such redemption is in compliance with applicable law, including the Company’s legal ability to pay a dividend to its shareholders, or (ii) in the event of Liquidation (as defined in our articles of association) of the Company, in which event the Company will first make the redemption payment (either in whole or, if less than the entire amount, on a pro rata basis based on the number of Preferred Shares held by each holder) before making any payment to holders of Ordinary Shares. The Preferred Shares will not be entitled to cumulative dividends.

Limit on Holdings of 4.99% of the Outstanding ADSs at any time

The Preferred Shares contain a provision preventing the holder from converting such number of Preferred Shares into ADSs to the extent that, as a result of such conversion, the holder would become the beneficial owner of more than 4.99% of the Company’s outstanding shares as determined under the rules promulgated under the Securities Exchange Act of 1934, as amended.

Veto Rights

The holders of a majority of the Preferred Shares have veto rights over the ability of the Company to (i) incur Indebtedness (as defined in our articles of association), subject to certain exceptions, (ii) enter into an M&A Event (as defined in our articles of association), (iii) voluntarily delist the trading of the Company’s securities on Nasdaq and (iv) authorize the creation of any security having rights, preferences and privileges equal to or greater than those of the Preferred Shares, including the issuance of additional Preferred Shares.

Right of First Refusal.

The Company would have a right of first refusal in the event that the EIB intends to sell, transfer, assign or otherwise dispose of any or all of the Preferred Shares.

American Depositary Shares

The Bank of New York Mellon, as depositary, registered and delivered American Depositary Shares, also referred to as ADSs. Each ADS represents 4,000 ordinary shares (or a right to receive 4,000 ordinary shares) deposited with the principal Tel Aviv office of either Bank Leumi or Bank Hapoalim, as custodian for the depositary. Each ADS also represents any other securities, cash or other property that may be held by the depositary. The depositary’s office at which the ADSs are administered is located at 101 Barclay Street, New York, New York 10286. The Bank of New York Mellon’s principal executive office is located at One Wall Street, New York, New York 10286.

You may hold ADSs either (A) directly (i) by having an American Depositary Receipt, also referred to as an ADR, which is a certificate evidencing a specific number of ADSs, registered in your name, or (ii) by having ADSs registered in your name in the Direct Registration System, or DRS, or (B) indirectly by holding a security entitlement in ADSs through your broker or other financial institution. If you hold ADSs directly, you are a registered ADS holder, also referred to as an ADS holder. This description assumes you are an ADS holder. If you hold the ADSs indirectly, you must rely on the procedures of your broker or other financial institution to assert the rights of ADS holders described in this section. You should consult with your broker or financial institution to find out what those procedures are.

The DRS is a system administered by The Depository Trust Company, or DTC, under which the depositary may register the ownership of uncertificated ADSs, which ownership is confirmed by periodic statements sent by the depositary to the registered holders of uncertificated ADSs.

As an ADS holder, we will not treat you as one of our shareholders and you will not have shareholder rights. Israeli law governs shareholder rights. The depositary will be the holder of the ordinary shares underlying your ADSs. As a registered holder of ADSs, you will have ADS holder rights. A deposit agreement among us, the depositary, ADS holders and all other persons indirectly or beneficially holding ADSs sets out ADS holder rights as well as the rights and obligations of the depositary. New York law governs the deposit agreement and the ADSs.

The following is a summary of the material provisions of the deposit agreement. For more complete information, you should read the entire deposit agreement and the form of ADR.

Dividends and Other Distributions

How will you receive dividends and other distributions on the shares?

The depositary has agreed to pay to ADS holders the cash dividends or other distributions that it or the custodian receives on ordinary shares or other deposited securities, after deducting its fees and expenses. You will receive these distributions in proportion to the number of ordinary shares your ADSs represent.

Cash. The depositary will convert any cash dividend or other cash distribution we pay on the ordinary shares into U.S. dollars, if it can do so on a reasonable basis and can transfer the U.S. dollars to the United States. If that is not possible or if any government approval is needed and cannot be obtained, the deposit agreement allows the depositary to distribute the foreign currency only to those ADS holders to whom it is possible to do so. It will hold the foreign currency it cannot convert for the account of the ADS holders who have not been paid. It will not invest the foreign currency and it will not be liable for any interest.

Before making a distribution, the depositary will deduct any withholding taxes, or other required governmental charges. The depositary will distribute only whole U.S. dollars and cents and will round fractional cents to the nearest whole cent. If the exchange rates fluctuate during a time when the depositary cannot convert the foreign currency, you may lose some or all of the value of the distribution.

Shares. The depositary may distribute additional ADSs representing any ordinary shares we distribute as a dividend or free distribution. The depositary will only distribute whole ADSs. It may sell ordinary shares which would require it to deliver a fraction of an ADS and distribute the net proceeds in the same way as it does with cash. If the depositary does not distribute additional ADSs, the outstanding ADSs will also represent the new shares. The depositary may sell a portion of the distributed ordinary shares sufficient to pay its fees and expenses in connection with that distribution.

Rights to purchase additional shares. If we offer holders of our securities any rights to subscribe for additional ordinary shares or any other rights, the depositary may make these rights available to ADS holders. If the depositary decides it is not legal and practical to make the rights available but that it is practical to sell the rights, the depositary will use reasonable efforts to sell the rights and distribute the proceeds in the same way as it does with cash. The depositary will allow rights that are not distributed or sold to lapse. In that case, you will receive no value for them.

If the depositary makes rights available to ADS holders, it will exercise the rights and purchase the ordinary shares on your behalf. The depositary will then deposit the ordinary shares and deliver ADSs to the persons entitled to them. It will only exercise rights if you pay it the exercise price and any other charges the rights require you to pay.

U.S. securities laws may restrict transfers and cancellation of the ADSs represented by ordinary shares purchased upon exercise of rights. For example, you may not be able to trade these ADSs freely in the United States. In this case, the depositary may deliver restricted depositary shares that have the same terms as the ADSs described in this section except for changes needed to put the necessary restrictions in place.

Other Distributions. The depositary will send to ADS holders anything else we distribute on deposited securities by any means it thinks is legal, fair and practical. If it cannot make the distribution in that way, the depositary will have a choice. It may decide to sell what we distributed and distribute the net proceeds, in the same way as it does with cash. Or, it may decide to hold what we distributed, in which case ADSs will also represent the newly distributed property. However, the depositary is not required to distribute any securities (other than ADSs) to ADS holders unless it receives reasonably satisfactory evidence from us that it is legal to make that distribution. The depositary may sell a portion of the distributed securities or property sufficient to pay its fees and expenses in connection with that distribution

The depositary is not responsible if it decides that it is unlawful or impractical to make a distribution available to any ADS holders. We have no obligation to register ADSs, shares, rights or other securities under the Securities Act. We also have no obligation to take any other action to permit the distribution of ADSs, shares, rights or anything else to ADS holders. This means that you may not receive the distributions we make on our ordinary shares or any value for them if it is illegal or impractical for us to make them available to you.

Deposit, Withdrawal and Cancellation

How are ADSs issued?

The depositary will deliver ADSs if you or your broker deposits ordinary shares or evidence of rights to receive ordinary shares with the custodian. Upon payment of its fees and expenses and of any taxes or charges, such as stamp taxes or stock transfer taxes or fees, the depositary will register the appropriate number of ADSs in the names you request and will deliver the ADSs to or upon the order of the person or persons that made the deposit.

How can ADS holders withdraw the deposited securities?

You may surrender your ADSs at the depositary’s office. Upon payment of its fees and expenses and of any taxes or charges, such as stamp taxes or stock transfer taxes or fees, the depositary will deliver the ordinary shares and any other deposited securities underlying the ADSs to the ADS holder or a person the ADS holder designates at the office of the custodian. Or, at your request, risk and expense, the depositary will deliver the deposited securities at its office, if feasible.

How do ADS holders interchange between certificated ADSs and uncertificated ADSs?

You may surrender your ADR to the depositary for the purpose of exchanging your ADR for uncertificated ADSs. The depositary will cancel that ADR and will send to the ADS holder a statement confirming that the ADS holder is the registered holder of uncertificated ADSs. Alternatively, upon receipt by the depositary of a proper instruction from a registered holder of uncertificated ADSs requesting the exchange of uncertificated ADSs for certificated ADSs, the depositary will execute and deliver to the ADS holder an ADR evidencing those ADSs.

Voting Rights

How do you vote?

ADS holders may instruct the depositary how to vote the number of deposited ordinary shares their ADSs represent. Otherwise, you won’t be able to exercise your right to vote unless you withdraw the shares. However, you may not know about the meeting sufficiently in advance to withdraw the shares.

The depositary will notify ADS holders of shareholders’ meetings and arrange to deliver our voting materials to them if we ask it to. Those materials will describe the matters to be voted on and explain how ADS holders may instruct the depositary how to vote. For instructions to be valid, they much reach the depositary by a date set by the depositary.

The depositary will try, as far as practical, subject to the laws of Israel and of our articles of association or similar documents, to vote or to have its agents vote the ordinary shares or other deposited securities as instructed by ADS holders. The depositary will only vote or attempt to vote as instructed or as described in the following sentence. If we ask the depositary to solicit your instructions at least 30 days before the meeting date but the depositary does not receive voting instructions from you by the specified date, it will consider you to have authorized and directed it to give a discretionary proxy to a person designated by us to vote the number of deposited securities represented by your ADSs. The depositary will give a discretionary proxy in those circumstances to vote on all questions at to be voted upon unless we notify the depositary that:

We are required to notify the depositary if one of the conditions specified above exists.

We cannot assure you that you will receive the voting materials in time to ensure that you can instruct the depositary to vote your shares. In addition, the depositary and its agents are not responsible for failing to carry out voting instructions or for the manner of carrying out voting instructions. This means that you may not be able to exercise your right to vote and there may be nothing you can do if your ordinary shares are not voted as you requested.

In order to give you a reasonable opportunity to instruct the Depositary as to the exercise of voting rights relating to Deposited Securities, if we request the Depositary to act, we agree to give the Depositary notice of any such meeting and details concerning the matters to be voted upon at least 30 days in advance of the meeting date.

Fees and Expenses

The depositary collects its fees for delivery and surrender of ADSs directly from investors depositing ordinary shares or surrendering ADSs for the purpose of withdrawal or from intermediaries acting for them. The depositary collects fees for making distributions to investors by deducting those fees from the amounts distributed or by selling a portion of distributable property to pay the fees. The depositary may collect its annual fee for depositary services by deduction from cash distributions or by directly billing investors or by charging the book-entry system accounts of participants acting for them. The depositary may collect any of its fees by deduction from any cash distribution payable to ADS holders that are obligated to pay those fees. The depositary may generally refuse to provide fee-attracting services until its fees for those services are paid.

From time to time, the depositary may make payments to us to reimburse and/or share revenue from the fees collected from ADS holders, or waive fees and expenses for services provided, generally relating to costs and expenses arising out of establishment and maintenance of the ADS program. In performing its duties under the deposit agreement, the depositary may use brokers, dealers or other service providers that are affiliates of the depositary and that may earn or share fees or commissions.

Payment of Taxes

You will be responsible for any taxes or other governmental charges payable on your ADSs or on the deposited securities represented by any of your ADSs.

Reclassifications, Recapitalizations and Mergers

Amendment and Termination

How may the deposit agreement be amended?

We may agree with the depositary to amend the deposit agreement and the ADSs without your consent for any reason. If an amendment adds or increases fees or charges, except for taxes and other governmental charges or expenses of the depositary for registration fees, facsimile costs, delivery charges or similar items, or prejudices a substantial right of ADS holders, it will not become effective for outstanding ADSs until 30 days after the depositary notifies ADS holders of the amendment. At the time an amendment becomes effective, you are considered, by continuing to hold your ADSs, to agree to the amendment and to be bound by the ADRs and the deposit agreement as amended.

How may the deposit agreement be terminated?

The depositary will terminate the deposit agreement at our direction by mailing notice of termination to the ADS holders at least 30 days prior to the date fixed in such notice for such termination. The depositary may also terminate the deposit agreement by mailing notice of termination to us and the ADS holders if 60 days have passed from the date on which the depositary told us it wants to resign but a successor depositary has not been appointed and accepted its appointment.

After termination, the depositary and its agents will do the following under the deposit agreement but nothing else: collect distributions on the deposited securities, sell rights and other property, and deliver ordinary shares and other deposited securities upon cancellation of ADSs. Four months after termination, the depositary may sell any remaining deposited securities by public or private sale. After that, the depositary will hold the money it received on the sale, as well as any other cash it is holding under the deposit agreement for the pro rata benefit of the ADS holders that have not surrendered their ADSs. It will not invest the money and has no liability for interest. The depositary’s only obligations will be to account for the money and other cash. After termination our only obligations will be to indemnify the depositary and to pay fees and expenses of the depositary that we agreed to pay.

Limitations on Obligations and Liability

Limits on our Obligations and the Obligations of the Depositary; Limits on Liability to Holders of ADSs

The deposit agreement expressly limits our obligations and the obligations of the depositary. It also limits our liability and the liability of the depositary. We and the depositary:

In the deposit agreement, we and the depositary agree to indemnify each other under certain circumstances.

Requirements for Depositary Actions

Before the depositary will deliver or register a transfer of ADSs, make a distribution on ADSs, or permit withdrawal of shares, the depositary may require:

The depositary may refuse to deliver ADSs or register transfers of ADSs when the transfer books of the depositary or our transfer books are closed or at any time if the depositary or we think it advisable to do so.

Your Right to Receive the Ordinary Shares Underlying your ADSs

ADS holders have the right to cancel their ADSs and withdraw the underlying ordinary shares at any time except:

This right of withdrawal may not be limited by any other provision of the deposit agreement.

Pre-release of ADSs

The deposit agreement permits the depositary to deliver ADSs before deposit of the underlying shares. This is called a pre-release of the ADSs. The depositary may also deliver ordinary shares upon cancellation of pre-released ADSs (even if the ADSs are canceled before the pre-release transaction has been closed out). A pre-release is closed out as soon as the underlying ordinary shares are delivered to the depositary. The depositary may receive ADSs instead of ordinary shares to close out a pre-release. The depositary may pre-release ADSs only under the following conditions: (1) before or at the time of the pre-release, the person to whom the pre-release is being made represents to the depositary in writing that it or its customer owns the ordinary shares or ADSs to be deposited; (2) the pre-release is fully collateralized with cash or other collateral that the depositary considers appropriate; and (3) the depositary must be able to close out the pre-release on not more than five business days’ notice. In addition, the depositary will limit the number of ADSs that may be outstanding at any time as a result of pre-release, although the depositary may disregard the limit from time to time if it thinks it is appropriate to do so.

Direct Registration System

In the deposit agreement, all parties to the deposit agreement acknowledge that DRS and the Profile Modification System, or Profile, will apply to uncertificated ADSs upon acceptance thereof to DRS by DTC. DRS is the system administered by DTC under which the depositary may register the ownership of uncertificated ADSs, which ownership will be confirmed by periodic statements sent by the depositary to the registered holders of uncertificated ADSs. Profile is a required feature of DRS that allows a DTC participant, claiming to act on behalf of a registered holder of ADSs, to direct the depositary to register a transfer of those ADSs to DTC or its nominee and to deliver those ADSs to the DTC account of that DTC participant without receipt by the depositary of prior authorization from the ADS holder to register that transfer.

In connection with and in accordance with the arrangements and procedures relating to DRS/Profile, the parties to the deposit agreement understand that the depositary will not determine whether the DTC participant that is claiming to be acting on behalf of an ADS holder in requesting registration of transfer and delivery described in the paragraph above has the actual authority to act on behalf of the ADS holder (notwithstanding any requirements under the Uniform Commercial Code). In the deposit agreement, the parties agree that the depositary’s reliance on and compliance with instructions received by the depositary through the DRS/Profile System and in accordance with the deposit agreement will not constitute negligence or bad faith on the part of the depositary.

Shareholder communications; inspection of register of holders of ADSs

The depositary will make available for your inspection at its office all communications that it receives from us as a holder of deposited securities that we make generally available to holders of deposited securities. The depositary will send you copies of those communications if we ask it to. You have a right to inspect the register of holders of ADSs, but not for the purpose of contacting those holders about a matter unrelated to our business or the ADSs.

For additional information regarding the history of changes to our share capital since April 1, 2023, please see “Item 5. Operating and Financial Review and Prospects - Liquidity and Capital Resources - Financing Activities” in our Annual Report on Form 20-F for the year ended December 31, 2025 filed with the SEC on April 1, 2026.

Transfer Agent and Depositary

The transfer agent and registrar for our Ordinary Shares is Vstock Transfer, LLC. The ADSs were issued pursuant to a Depositary Agreement entered into with The Bank of New York Mellon, which acts as depositary.

Enforcement 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 the Israeli experts named in this prospectus, substantially all of whom reside outside the United States, may be difficult to obtain within the United States. Furthermore, because substantially all of our assets and substantially all of our directors and officers are located outside the United States, any judgment obtained in the United States against us or any of our directors and officers may not be collectible within the United States.

We have irrevocably appointed Puglisi & Associates as our agent to receive service of process in any action against us in any U.S. federal or state court arising out of this offering or any purchase or sale of securities in connection with this offering. The address of our agent is 850 Library Avenue, Suite 204, Newark, Delaware.

We have been informed by our legal counsel in Israel, Goldfarb Gross Seligman & Co., that it may be difficult to initiate an action with respect to U.S. securities law in Israel. Israeli courts may refuse to hear a claim based on an alleged violation of U.S. securities laws reasoning that Israel is not the most appropriate forum to hear 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 may also be governed by Israeli law.

Subject to certain time limitations and legal procedures, Israeli courts may enforce a U.S. judgment in a civil matter which, subject to certain exceptions, is non-appealable, including judgments based upon the civil liability provisions of the Securities Act and the Exchange Act and including a monetary or compensatory judgment in a non-civil matter, provided that:

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. Under existing Israeli law, a foreign judgment payable in foreign currency may be paid in Israeli currency at the rate of exchange in force on the date of the payment. Current Israeli exchange control regulations also permit a judgment debtor to 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.

PLAN OF DISTRIBUTION

On September 10, 2025, we entered into the Purchase Agreement with YA. The Purchase Agreement provides that, upon the terms and subject to the conditions set forth therein, YA is committed to purchase up to $15.0 million in ADSs during the Commitment Period. From time to time, and at our sole discretion, we may present YA with Advance Notices to purchase our ADSs. The ADSs would be purchased pursuant to the Purchase Agreement at 97% of the lowest daily VWAP during the period of three consecutive trading days commencing on the trading day immediately following YA’s receipt of an Advance Notice.

The ADSs offered by this prospectus are being offered by the Selling Shareholder. The Selling Shareholder is an “underwriter” within the meaning of Section 2(a)(11) of the Securities Act. We have agreed in the Purchase Agreement to provide customary indemnification to YA.

It is possible that our shares may be sold from time to time by YA in one or more of the following manners:

In order to comply with the securities laws of certain states, if applicable, the shares may be sold only through registered or licensed brokers or dealers. In addition, in certain states, the shares may not be sold unless they have been registered or qualified for sale in the state or an exemption from the state’s registration or qualification requirement is available and complied with.

YA is an “underwriter” within the meaning of Section 2(a)(11) of the Securities Act.

YA has agreed that, during the term of the Purchase Agreement, neither YA nor its affiliates will engage in any short sales or hedging transactions with respect to the ADSs, provided that YA and its affiliates may enter into Permitted Sales.

We have advised YA that it is required to comply with Regulation M promulgated under the Exchange Act. With certain exceptions, Regulation M precludes the Selling Shareholder, any affiliated purchasers, and any broker-dealer or other person who participates in the distribution from bidding for or purchasing, or attempting to induce any person to bid for or purchase any security which is the subject of the distribution until the entire distribution is complete. Regulation M also prohibits any bids or purchases made in order to stabilize the price of a security in connection with the distribution of that security. All of the foregoing may affect the marketability of the securities offered by this prospectus.

We will pay the expenses incident to the registration under the Securities Act of the offer and sale of our ADSs covered by this prospectus by the Selling Shareholder. We estimate that our total expenses for the offering will be approximately $0.1 million (excluding the Commitment Shares). As consideration for its irrevocable commitment to purchase our ADSs under the Purchase Agreement, we agreed to issue the Commitment Shares to the Selling Shareholder, calculated as 1% of the Commitment Amount.

Expenses Relating to the Offering

The following table sets forth the costs and expenses payable in connection with the sale of ADSs in the offering. All amounts are estimated except the SEC registration fee. Except as otherwise noted, all the expenses below will be paid by us.

Legal Matters

The validity of our Ordinary Shares and other legal matters concerning this offering relating to Israeli law will be passed upon for us by Goldfarb Gross Seligman & Co., Israel. Certain legal matters in connection with this offering relating to U.S. federal law will be passed upon for us by Lucosky Brookman LLP, Woodbridge, New Jersey.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 6. Indemnification of Directors and Officers.

Under the Companies Law, a company may not exculpate an office holder from liability for a breach of the fiduciary duty. An Israeli company may exculpate an office holder in advance from liability to the company, in whole or in part, for damages caused to the company as a result of a breach of duty of care but only if a provision authorizing such exculpation is included in its articles of association. Our articles of association include such a provision. The company may not exculpate in advance a director from liability arising due to the breach of his or her duty of care in the event of a prohibited dividend or distribution to shareholders.

Under the Companies Law and the Israeli Securities Law, 5728-1968 (the “Securities Law”) a company may indemnify an office holder in respect of the following liabilities, payments and expenses incurred for acts performed by him or her as an office holder, either in advance of an event or following an event, provided its articles of association include a provision authorizing such indemnification:

An “Administrative Procedure” is defined as a procedure pursuant to chapters H3 (Monetary Sanction by the Israeli Securities Authority), H4 (Administrative Enforcement Procedures of the Administrative Enforcement Committee) or I1 (Arrangement to prevent Procedures or Interruption of procedures subject to conditions) to the Securities Law.

Under the Companies Law and the Securities Law, a company may insure an office holder against the following liabilities incurred for acts performed by him or her as an office holder if and to the extent provided in the company’s articles of association:

Under the Companies Law, a company may not indemnify, exculpate or insure an office holder against any of the following:

Under the Companies Law, exculpation, indemnification and insurance of office holders must be approved by the compensation committee and the board of directors and, with respect to directors or controlling shareholders, their relatives and third parties in which controlling shareholders have a personal interest, also by the shareholders.

Our articles of association permit us to exculpate, indemnify and insure our office holders to the fullest extent permitted or to be permitted by law. Our office holders are currently covered by a directors’ and officers’ liability insurance policy. As of the date of this registration statement, no claims for directors’ and officers’ liability insurance have been filed under this policy and we are not aware of any pending or threatened litigation or proceeding involving any of our office holders, including our directors, in which indemnification is sought.

We have entered into agreements with each of our directors and executive officers exculpating them, to the fullest extent permitted by law and our articles of association, and undertaking to indemnify them to the fullest extent permitted by law and our articles of association. This indemnification is limited to events determined as foreseeable by the board of directors based on our activities, and to an amount or according to criteria determined by the board of directors as reasonable under the circumstances.

The maximum indemnification amount set forth in such agreements is limited to an amount which shall not exceed 25% of our net assets based on our most recently audited or reviewed financial statements prior to actual payment of the indemnification amount. Such maximum amount is in addition to any amount paid (if paid) under insurance and/or by a third-party pursuant to an indemnification arrangement. However, in the opinion of the SEC, indemnification of office holders for liabilities arising under the Securities Act is against public policy and therefore unenforceable.

ITEM 7. Recent Sales of Unregistered Securities.

Since April 1, 2023, our issued share capital has changed as provided below.

From February 1, 2023 until August 23, 2023, we issued 166 ADSs to Prof. Matthias Dobbelstein as consideration for scientific advisory board services.

On July 31, 2023, we issued 1,585 ADSs to MPG and 114 ADSs to MBM Science Bridge GmbH pursuant to the License Agreement, dated June 4, 2023, by and among the Company, Max Planck Innovation GmbH and Georg-August-Universität Göttingen Stiftung Öffentlichen Rechts Universitätsmedizin Göttingen.

On September 19, 2023, we issued (i) in a registered direct offering 40,000 ADSs and pre-funded warrants to purchase up to 7,466 ADSs, at an exercise price of $0.1 per ADS, at a purchase price of $116 per ADS and $116 per pre-funded warrant, and (ii) in concurrent private placement unregistered warrants to purchase up to 11,466 ADSs. The warrants have an exercise price of $116 per ADS and are immediately exercisable upon issuance for a period of five and one-half years. The Company received a net sum of $1,151 after deduction of underwriter discount and issuance expenses of $165.

On December 29, 2023 in connection with the warrant inducement letters we issued 260,655 ADSs in the aggregate from the exercise of the Existing Warrants at an exercise price of $6.50 per ADS, and issued 521,310 new warrants with an exercise price of $0.65 per ADS, in addition to placement agent warrants to acquire 15,639 ADSs to our placement agent in such transaction or its designees, each with an exercise price of $8.125.

From August 2024 until December 2024, we issued RK Stone Miami LLC pre-funded warrants to acquire an aggregate of 64,644 ADSs for an aggregate purchase price of $2.0 million.

On February 19, 2025, we issued 8,073 ADSs to LCK JNK 1, LLC upon its cashless exercise of pre-funded warrants to acquire 8,075 ADSs that it acquired from RK Stone Miami LLC.

Between September 10, 2025 and August 15, 2026, we issued to the selling shareholder an aggregate of 3,546 Commitment Shares pursuant to the Purchase Agreement.

(a) Exhibits

EXHIBIT INDEX

 

*	Filed herewith.
**	Previously filed.
+	Certain confidential portions of this exhibit have been redacted from the publicly filed document because such portions are (i) not material and (ii) would be competitively harmful if publicly disclosed.

ITEM 9. Undertakings.

(b) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the provisions described in Item 6 hereof, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
