OUR COMPANY

Overview

We are a leading energy company powered by proprietary thermal energy storage, or TES, technology, specializing in energy supply to industrial clients through our patented bGen™ systems. Our unique technology enables full vertical integration from renewable energy assets and grid management to reliable end-customer delivery for factories requiring power and heat. We combine this breakthrough TES with a fully integrated energy optimization platform to create a 360° solution that transforms inflexible industrial energy needs into flexible, clean operations.

Sustainable energy and power system resilience are critical infrastructure challenges as the rapid global expansion of data centers, driven in part by advances in computing and artificial intelligence, or AI, is projected to significantly increase electricity demand. According to the International Energy Agency, global electricity consumption by data centers is expected to more than double to about 945 terawatt-hours by 2030, up from approximately 415 TWh in 2024, underscoring the scale of future demand growth and its implications for energy systems planning (IEA Energy and AI report, 2025). This rising demand places additional pressure on power grids and highlights the importance of dispatchable, grid-responsive technologies, flexible energy delivery, and adaptable industrial energy strategies to support both reliability and the clean energy transition (IEA Energy and AI report, 2025). Brenmiller addresses this need through advanced economical models, proprietary TES technology, and a differentiated commercial strategy. Our bGen™ systems can convert renewable electricity into stored thermal energy, and/or capture and reuse waste heat, and deliver controlled steam output. By aligning variable renewable generation with real time industrial heat demand, we reduce carbon emissions and energy costs while enabling clients to strengthen their energy independence and long-term operational resilience.

We have developed our bGen™ technology over the past fourteen years and validated it across three generations of demonstration units at multiple sites worldwide. The system stores heat in crushed rock at temperatures of up to 1,400 degrees Fahrenheit, 760 degrees Celsius, and integrates bCubes™ thermal storage units, electric heaters, heat exchangers, electricity to heat conversion, and steam generation within a single durable and independent unit. The use of crushed rock as the storage medium avoids hazardous environmental impacts and provides long term durability, maintaining performance over tens of thousands of charge and discharge cycles without degradation or the need to replace the storage material. The system can be charged from multiple energy sources, including residual heat and renewable or grid supplied electricity via embedded electric heaters, and dispatches thermal energy on demand as saturated steam for industrial processes or as superheated steam to drive steam turbines.

In 2023, we launched our Energy-as-a-Service, or EaaS, model, pursuant to which we finance the project, install systems at customer sites, provide ongoing Operations and Maintenance, or O&M, and sell thermal energy at fixed rates, enabling customers to reduce energy costs, concentrate on their core operations, support their transition to clean energy, and enhance energy stability, while allowing us to generate recurring and diversified revenue streams in this expanding market. Building on this model, we are expanding our strategy through BrenX to develop, own and operate integrated industrial energy resource centers that combine renewable generation, battery energy storage, thermal energy storage and industrial energy services with the objective of creating long-term recurring infrastructure-based revenue streams.

Recent Developments

July 2025 Private Placement

On July 25, 2025, we entered into a securities purchase agreement, or the SPA, with Alpha Capital Anstalt, or Alpha, pursuant to which we agreed to issue and sell to Alpha, subject to certain conditions, up to an aggregate of $25 million in securities across multiple tranches, consisting of preferred shares, pre-funded warrants, and ordinary warrants.

Between July 2025 and June 2026, we completed multiple closings under the SPA, including an initial closing on July 28, 2025 pursuant to which we issued to Alpha pre-funded warrants and ordinary warrants, or the July Ordinary Warrants, and subsequent closings on September 29, 2025, December 3, 2025, December 30, 2025, February 13, 2026, March 10, 2026, April 27, 2026, June 1, 2026, and June 11, 2026 pursuant to which we issued to Alpha preferred shares and accompanying ordinary warrants, and with the July Ordinary Warrants, the Ordinary Warrants.

On July 13, 2026, we closed an additional subsequent funding from Alpha for $1,000 thousand of gross proceeds, or the July 2026 Subsequent Funding, pursuant to which we issued to Alpha (i) 1,000 preferred shares with a stated value of $1,000 per share, convertible into ordinary shares at a fixed conversion price of $0.9175 per share, and (ii) ordinary warrants to purchase 1,089,918 ordinary shares at an exercise price of $14.56 per share, which are exercisable upon issuance and will expire five years from the initial exercise date.

As a result of the pricing of the July 2026 Subsequent Funding, under the anti-dilution and ratchet adjustment provisions contained in our Amended and Restated Articles of Association, the conversion price of the preferred shares previously issued pursuant to the SPA was adjusted to $0.9175.

The net proceeds from the July 2026 Subsequent Funding will be used for general corporate purposes, working capital and execution of our commercial TES projects across Europe, the U.S. and the Middle East.

RISK FACTORS

Investing in our securities involves risks. Please carefully consider the risk factors described below and those contained in our periodic reports filed with the Securities and Exchange Commission, or SEC, including those set forth under the caption “Summary Risk Factors” and “Item 3. Key Information – D. Risk Factors” in our 2025 Annual Report, which is incorporated by reference into this prospectus. Before making an investment decision, you should carefully consider these risks as well as other information we include or incorporate by reference in this prospectus. You should be able to bear a complete loss of your investment.

Risks Related to this Offering and Our Ordinary Shares

The number of Ordinary Shares that have been or may be registered for resale pursuant to the registration statement of which this prospectus forms a part and existing resale registration statements is significant in relation to our currently outstanding Ordinary Shares.

We have filed multiple registration statements registering for resale a substantial number of Ordinary Shares, including Ordinary Shares issuable upon the exercise or conversion of outstanding warrants and preferred shares held by Alpha. The aggregate number of shares covered by these registration statements, including shares underlying convertible and exercisable securities, is substantial and could create a significant overhang in the market for our Ordinary Shares.

The sale of all or a substantial portion of these shares in the market within a short period of time could adversely affect the market price of our Ordinary Shares during the period these registration statements remain effective and could also adversely affect our ability to raise equity capital.

There can be no assurance that we will be able to maintain continued Nasdaq listing criteria.

On August 12, 2024, we received a written notice from the Nasdaq Stock Market indicating that we are not in compliance with the minimum bid price requirement for continued listing set forth in Nasdaq Listing Rule 5550(a)(2), which requires listed securities to maintain a minimum bid price of $1.00 per share. Under Nasdaq Listing Rule 5810(c)(3)(A), we were granted a grace period of 180 calendar days to regain compliance with the minimum bid price requirement. On January 16, 2025, we announced that we received a written notice from Nasdaq that we have regained compliance with the minimum bid price requirement for continued listing set forth in Nasdaq Listing Rule 5550(a)(2). The Nasdaq staff made this determination of compliance after the closing bid price of our ordinary shares on Nasdaq was at $1.00 per share or greater for the 10 consecutive business days prior to the date of the notice. Accordingly, we have regained compliance with Nasdaq Listing Rule 5550(a)(2), and Nasdaq considers the prior bid price deficiency matter now closed. However, there can be no assurance that we will be able to maintain compliance with the minimum bid price requirement or that we will otherwise be in compliance with other Nasdaq listing criteria.

In the past year, we have effected two reverse share splits in order to support compliance with Nasdaq’s minimum bid price requirement, including (i) a 7-for-1 reverse share split effected on January 26, 2026 and (ii) a 5-for-1 reverse share split effected on April 15, 2026. There can be no assurance that these reverse share splits will result in sustained compliance with the minimum bid price requirement.

Pursuant to Nasdaq Listing Rule 5810(c)(3)(A)(iv), because we have effected one or more reverse share splits within the prior one-year period, if our ordinary shares again have a closing bid price below $1.00 per share for 30 consecutive business days, we would not be eligible for an additional compliance period and Nasdaq staff may issue a delisting determination without providing a further cure period. As a result, if our ordinary shares again trade below $1.00 per share for 30 consecutive business days, we could be subject to immediate delisting from Nasdaq.

If, for any reason, Nasdaq delists our securities from trading on its exchange and we are not able to list our securities on another national securities exchange, we expect our securities could be quoted on an over-the-counter market. If this were to occur, we could face significant material adverse consequences, including:

	●	a limited availability of market quotations for our securities;

	●	reduced liquidity for our securities;

	●	a decrease in the number of institutional and general investors that will consider investing in our Ordinary Shares; and

	●	a determination that our ordinary shares are a “penny stock” which will require brokers trading in our Ordinary Shares to adhere to more stringent rules and possibly result in a reduced level of trading activity in the secondary trading market for our securities.

Substantial future sales or other issuances of our Ordinary Shares could depress the market for our Ordinary Shares.

Sales of a substantial number of Ordinary Shares and any future sales of a substantial number of Ordinary Shares in the public market, including the issuance of shares or any shares issuable upon the conversion of the Preferred Shares issued to Alpha or the exercise of the Warrants issued to Alpha or pre-funded warrants and warrants issuable to Alpha, or the perception by the market that those sales could occur, could cause the market price of our Ordinary Shares to decline or could make it more difficult for us to raise funds through the sale of equity and equity-related securities in the future at a time and price that our management deems acceptable, or at all. In addition, as opportunities present themselves, we may enter into financing or similar arrangements in the future, including the issuance of debt securities, preferred shares or Ordinary Shares, which could also depress the market for our Ordinary Shares. We cannot predict the effect, if any, that market sales of those Ordinary Shares or the availability of those shares for sale will have on the market price of our Ordinary Shares.

In connection with the July 2025 Private Placement, under the terms of the SPA, subject to certain conditions and as long as any Preferred Shares or accompanying ordinary warrants are outstanding, Alpha has the right to purchase additional preferred shares and warrants from us, which has resulted and may result in further dilution as well.

We have outstanding warrants and preferred shares, some of which contain “full-ratchet” anti-dilution protection, which have caused significant dilution to our shareholders and may cause further significant dilution to our shareholders.

We have outstanding warrants, which are exercisable into ordinary shares, and preferred shares, which are convertible into ordinary shares. The issuance of the ordinary shares upon the exercise of the warrants or the conversion of such preferred shares would dilute the percentage ownership interest of all shareholders, might dilute the book value per share of our ordinary shares and would increase the number of our publicly traded shares, which could depress the market price of our ordinary shares. The warrants issued to Alpha on July 28, 2025, September 29, 2025, December 3, 2025, December 30, 2025, February 13, 2026, March 10, 2026, April 27, 2026, June 1, 2026, June 15, 2026, and July 13, 2026 and the preferred shares issued to Alpha on September 29, 2025, December 3, 2025, December 30, 2025, February 13, 2026, March 10, 2026 April 27, 2026, June 1, 2026, June 15, 2026, and July 13, 2026 contain a “full-ratchet” anti-dilution provision which, subject to limited exceptions, reduce the exercise price of the warrants or the conversion price of the preferred shares (and increase the number of shares issuable) in the event that we in the future issue ordinary shares, or securities convertible into or exercisable to purchase ordinary shares, including any securities issued to Alpha in connection to the SPA, at a price per share lower than the applicable exercise price or conversion price then in effect.

You may experience future dilution as a result of future equity offerings and other issuances of our securities.

In order to raise additional capital, we may in the future offer additional Ordinary Shares or other securities convertible into or exchangeable for our Ordinary Shares prices that may not be the same as the price per share paid by the investors in this offering. We may not be able to sell shares or other securities in any other offering at a price per share that is equal to or greater than the price per share paid by the investors in this offering, and investors purchasing shares or other securities in the future could have rights superior to existing shareholders. The price per share at which we sell additional Ordinary Shares or securities convertible into Ordinary Shares in future transactions may be higher or lower than the price per share paid to the selling shareholders. Our shareholders will incur dilution upon exercise of any outstanding share options, warrants or other convertible securities or upon the issuance of Ordinary Shares under our share incentive programs.

Any additional capital raised through the sale of equity or equity-backed securities may dilute our shareholders’ ownership percentages and could also result in a decrease in the market value of our equity securities.

The terms of any securities issued by us in future capital transactions may be more favorable to new investors, and may include preferences, superior voting rights and the issuance of warrants or other derivative securities, which may have a further dilutive effect on the holders of any of our securities then outstanding.

In addition, we may incur substantial costs in pursuing future capital financing, including investment banking fees, legal fees, accounting fees, securities law compliance fees, printing and distribution expenses and other costs. We may also be required to recognize non-cash expenses in connection with certain securities we issue, such as convertible notes and warrants, which may adversely impact our financial condition.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

Some of the statements made under “Risk Factors,” “Use of Proceeds,” and elsewhere in this prospectus, including in our 2025 Annual Report, incorporated by reference herein, and other information included or incorporated by reference in this prospectus, constitute forward-looking statements. Forward-looking statements are often characterized by the use of forward-looking terminology such as “may,” “will,” “expect,” “anticipate,” “plan,” “estimate,” “continue,” “believe,” “should,” “intend,” “project,” “predict,” “potential” or other similar words, but are not the only way these statements are identified.

These forward-looking statements may include, but are not limited to, statements relating to our objectives, plans and strategies, statements that contain projections of results of operations or of financial condition, expected capital needs and expenses, statements relating to the research, development, completion and use of our products, and all statements (other than statements of historical facts) that address activities, events or developments that we intend, expect, project, believe or anticipate will or may occur in the future.

Forward-looking statements are not guarantees of future performance and are subject to risks and uncertainties. We have based these forward-looking statements on assumptions and assessments made by our management in light of their experience and their perception of historical trends, current conditions, expected future developments and other factors they believe to be appropriate.

Important factors that could cause actual results, developments and business decisions to differ materially from those anticipated in these forward-looking statements include, among other things:

	●	our planned level of revenues and capital expenditures;

	●	our ability to market and sell our products;

	●	our plans to continue to invest in research and development to develop technology for both existing and new products;

	●	our ability to maintain our relationships with suppliers, manufacturers, and other partners;

	●	our ability to maintain or protect the validity of our European, U.S., and other patents and other intellectual property;

	●	our ability to retain key executive members;

	●	our ability to internally develop and protect new inventions and intellectual property;

	●	our ability to expose and educate the industry about the use of our products;

	●	our expectations regarding our tax classifications;

	●	our ability to maintain compliance with Nasdaq’s continued listing requirements;

	●	interpretations of current laws and the passages of future laws; and

	●	general market, political, and economic conditions in the countries in which we operate including those related to recent unrest and actual or potential armed conflict in Israel and other parts of the Middle East.

These statements are only current predictions and are subject to known and unknown risks, uncertainties, and other factors that may cause our or our industry’s actual results, levels of activity, performance or achievements to be materially different from those anticipated by the forward-looking statements. We discuss many of these risks in this prospectus in greater detail under the heading “Risk Factors” and elsewhere in this prospectus. You should not rely upon forward-looking statements as predictions of future events.

Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, levels of activity, performance, or achievements. Except as required by law, we are under no duty to update or revise any of the forward-looking statements, whether as a result of new information, future events or otherwise, after the date of this prospectus.

USE OF PROCEEDS

We will not receive any proceeds from the sale of the Ordinary Shares by the selling shareholder. All net proceeds from the sale of the Ordinary Shares covered by this prospectus will go to the selling shareholder. However, we will receive cash proceeds equal to the exercise price of any July 2026 Ordinary Warrants that are exercised.

We intend to use the proceeds from the exercise of the July 2026 Ordinary Warrants for general corporate purposes, working capital, potential discharge of existing indebtedness and execution of our commercial TES projects across Europe, the U.S. and the Middle East.

SELLING SHAREHOLDER

On July 25, 2025, we entered into a securities purchase agreement with Alpha in connection with the July 2025 Private Placement. We are registering up to 7,201,960 Ordinary Shares, which is the aggregate of (i) 1,089,918 Ordinary Shares issuable upon the conversion of 1,000 preferred shares, with a stated value of $1,000 per share and conversion price of $0.9175 per share, (ii) up to an additional 1,089,918 Ordinary Shares issuable upon the conversion of 1,000 preferred shares, reflecting 200% of the maximum number of shares issuable upon conversion of the July 2026 Convertible Preferred Shares, due to the potential effect of anti-dilution adjustments contained in our Amended and Restated Articles of Association (without taking into account any limitations on the conversion of such July Convertible Preferred Shares set forth therein), (iii) 1,089,918 Ordinary Shares issuable upon the exercise of ordinary warrants, with an exercise price of $14.56 per share and (iv) 3,932,206 Ordinary Shares issuable upon the conversion of previously issued and outstanding preferred shares, with a conversion price of $0.9175 per share, reflecting 200% of the maximum number of shares issuable upon conversion of such preferred shares, due to the potential effect of anti-dilution adjustments contained in our Amended and Restated Articles of Association (without taking into account any limitations on the conversion of such Preferred Shares set forth therein) (see “Our Company—Recent Developments—July 2025 Private Placement” for additional information).

We are registering the Ordinary Shares in order to permit the selling shareholder to offer the Ordinary Shares for resale from time to time.

Other than the relationships described herein, and in previous public disclosures by Alpha, to our knowledge, the selling shareholder has not had any material relationship with us within the past three years.

Any selling shareholder that is an affiliate of broker-dealers and any participating broker-dealers would be deemed to be an “underwriter” within the meaning of the Securities Act, and any commissions or discounts given to any such selling shareholder or broker-dealer may be regarded as underwriting commissions or discounts under the Securities Act. To our knowledge, the selling shareholder listed below is not a broker-dealer or affiliate of a broker-dealer.

The table below lists the selling shareholder and other information regarding the beneficial ownership of the Ordinary Shares by the selling shareholder. The second column lists the number of Ordinary Shares beneficially owned by the selling shareholder, based on its ownership of the Ordinary Shares, as of the date set forth in the relevant footnote next to the selling shareholder’s name. The fourth column assumes the sale of all of the Ordinary Shares offered by the selling shareholder pursuant to this prospectus.

Because the number of Ordinary Shares may be adjusted for reverse and forward share splits, share dividends, share combinations and other similar transactions, the number of Ordinary Shares that will actually be issued may be more or less than the number of Ordinary Shares being offered by this prospectus.

The term “selling shareholder” also includes any transferees, pledgees, donees, or other successors in interest to the selling shareholder named in the table below. Unless otherwise indicated, to our knowledge, the selling shareholder named in the table below has sole voting and investment power (subject to applicable community property laws) with respect to the Ordinary Shares set forth opposite its name. We will file a supplement to this prospectus (or a post-effective amendment to the registration statement of which this prospectus forms a part, if necessary) to name successors to the selling shareholder who is able to use this prospectus to resell the securities registered hereby.

The columns titled “Maximum Number of Shares to be Sold Pursuant to this Prospectus” and “Shares Owned Immediately After Sale of Maximum Number of Shares in this Offering” assume no potential effect of anti-dilution adjustments to the $0.9175 conversion price of the July 2026 Convertible Preferred Shares and an exercise price of $14.56 for the Ordinary Warrants.

Under the terms of the Preferred Shares and the Ordinary Warrants, a selling shareholder may not convert the Preferred Shares or exercise the Ordinary Warrants to the extent such selling shareholder or any of its affiliates would beneficially own a number of shares of our Ordinary Shares which would exceed 9.99% of our outstanding shares.

The selling shareholder may sell all, some or none of its shares in this offering. See “Plan of Distribution.”

PLAN OF DISTRIBUTION

The selling shareholder of the securities and any of its pledgees, assignees and successors-in-interest may, from time to time, sell any or all of the securities covered hereby on the principal trading market or any other share exchange, market or trading facility on which the securities are traded or in private transactions. These sales may be at fixed or negotiated prices. The selling shareholder may use any one or more of the following methods when selling securities:

	●	ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

	●	block trades in which the broker-dealer will attempt to sell the securities as agent but may position and resell a portion of the block as principal to facilitate the transaction;

	●	purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

	●	an exchange distribution in accordance with the rules of the applicable exchange;

	●	privately negotiated transactions;

	●	settlement of short sales;

	●	in transactions through broker-dealers that agree with the selling shareholder to sell a specified number of such securities at a stipulated price per security;

	●	through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

	●	a combination of any such methods of sale; or

	●	any other method permitted pursuant to applicable law.

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

Broker-dealers engaged by the selling shareholder may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the selling shareholder (or, if any broker-dealer acts as agent for the purchaser of securities, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with Rule 2440 of the Financial Industry Regulatory Authority, or FINRA, and in the case of a principal transaction a markup or markdown in compliance with FINRA IM-2440.

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

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

We are required to pay certain fees and expenses incurred by us incident to the registration of the securities.

The resale securities will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale securities covered hereby may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

Under applicable rules and regulations under the Securities Exchange Act of 1934, as amended, or the Exchange Act, any person engaged in the distribution of the resale securities may not simultaneously engage in market making activities with respect to the Ordinary Shares for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the selling shareholder will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of the Ordinary Shares by the selling shareholder or any other person. We will make copies of this prospectus available to the selling shareholder and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).

Offer Restrictions Outside the United States

Other than in the United States, no action has been taken by us or the selling shareholder that would permit a public offering of the securities offered by this prospectus in any jurisdiction where action for that purpose is required. The securities offered by this prospectus may not be offered or sold, directly or indirectly, nor may this prospectus or any other offering material or advertisements in connection with the offer and sale of any such securities be distributed or published in any jurisdiction, except under circumstances that will result in compliance with the applicable rules and regulations of that jurisdiction.

ENFORCEABILITY OF CIVIL LIABILITIES

We are incorporated under the laws of the State of Israel. Service of process upon us and upon our directors and officers and the Israeli experts named in the registration statement of which this prospectus forms a part, a substantial majority of whom reside outside of the United States, may be difficult to obtain within the United States. Furthermore, because substantially all of our assets and a substantial number of our directors and officers are located outside of 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 been informed by our legal counsel in Israel, Sullivan & Worcester Tel-Aviv (Har-Even & Co.), Tel Aviv, Israel, that it may be difficult to assert U.S. securities law claims in original actions instituted in Israel. Israeli courts may refuse to hear a claim based on a violation of U.S. securities laws because Israel is not the most appropriate forum to bring such a claim. In addition, even if an Israeli court agrees to hear a claim if U.S. law is found to be applicable, the content of applicable U.S. law must be proved as a fact which can be a time-consuming and costly process. Certain matters of the procedure will also be governed by Israeli law.

Subject to specified 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 among other things:

●

the judgment is obtained after due process before a court of competent jurisdiction, according to the laws of the state in which the judgment is given;

●

the judgment is final and is not subject to any right of appeal;

●

the prevailing law of the foreign state in which the judgment was rendered allows for the enforcement of judgments of Israeli courts. However, the court may enforce a foreign judgment, even without reciprocity, based on the request of the Attorney General, under certain circumstances;

●

the liabilities under the judgment are enforceable according to the laws of the State of Israel and the judgment and the enforcement of the civil liabilities set forth in the judgment is not contrary to public policy in Israel;

●

the judgment was not obtained by fraud, there was a reasonable opportunity for the defendant to present their case, the judgment was given by an authorized court to issue it under the applicable international private law rules in Israel, and the judgment does not conflict with any other valid judgments in the same matter between the same parties;

●

an action between the same parties in the same matter is not pending in any Israeli court at the time the lawsuit is instituted in the foreign court;

●

the judgment is enforceable according to the laws of the foreign state in which it was granted; and

●

enforcement may be denied if it could harm the sovereignty or security of the State of Israel.

If a foreign judgment is declared enforceable by an Israeli court, it generally will be payable in Israeli currency. The conversion to Israeli currency will be based on the latest official exchange rate published by the Bank of Israel before the payment date. However, the obligated party will fulfill its duty by the judgment even if they choose to make the payment in the same foreign currency, subject to the laws governing the foreign currency applicable at that time.

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.

WHERE YOU CAN FIND ADDITIONAL INFORMATION

We are an Israeli company and are a “foreign private issuer” as defined in Rule 3b-4 under the Exchange Act. We are subject to the informational requirements of the Exchange Act applicable to foreign private issuers.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 8. Indemnification of Directors, Officers and Employees

Indemnification

The Israeli Companies Law 5759-1999, or the Companies Law, and the Israeli Securities Law, 5728-1968, or the Securities Law, provide that a company may indemnify an officeholder against the following liabilities and expenses incurred for acts performed by him or her as an officeholder, either pursuant to an undertaking made in advance of an event or following an event, provided its articles of association include a provision authorizing such indemnification:

●

a financial liability imposed on him or her in favor of another person by any judgment concerning an act performed in his or her capacity as an officeholder, including a settlement or arbitrator’s award approved by a court;

●

reasonable litigation expenses, including attorneys’ fees, expended by the officeholder (a) as a result of an investigation or proceeding instituted against him or her by an authority authorized to conduct such investigation or proceeding, provided that (1) no indictment (as defined in the Companies Law) was filed against such officeholder as a result of such investigation or proceeding; and (2) no financial liability as a substitute for the criminal proceeding was imposed upon him or her as a result of such investigation or proceeding, or, if such financial liability was imposed, it was imposed with respect to an offense that does not require proof of criminal intent; or (b) in connection with a monetary sanction;

●

reasonable litigation expenses, including attorneys’ fees, expended by the officeholder or imposed on him or her by a court: (1) in proceedings that the company institutes, or that are instituted on the company’s behalf, or by another person, against him or her; (2) in criminal proceedings of which he or she was acquitted; or (3) as a result of a conviction for a crime that does not require proof of criminal intent;

●

expenses incurred by an officeholder in connection with an Administrative Procedure under the Securities Law, including reasonable litigation expenses and reasonable attorneys’ fees. 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; and

●

any other liability or expense for which it is permitted and/or will be permitted to indemnify an officeholder.

The Companies Law also permits, if a company includes such provisions in its articles of association, to undertake in advance to indemnify an officeholder, provided that if such indemnification relates to financial liability imposed on him or her, as described above, then the undertaking should be limited and shall detail the following foreseen events and amount or criterion:

●

to events that in the opinion of the board of directors can be foreseen based on the company’s activities at the time that the undertaking to indemnify is made; and

●

in amount or criterion determined by the board of directors, at the time of the giving of such undertaking to indemnify, to be reasonable under the circumstances.

II-1

Under the Companies Law, exemption, indemnification and insurance of officeholders must be approved by the compensation committee and the board of directors (and, with respect to directors and the chief executive officer, by the shareholders). However, under regulations promulgated under the Companies Law, the insurance of officeholders does not require shareholder approval and may be approved by only the compensation committee if the engagement terms are determined in accordance with the company’s compensation policy, which was approved by the shareholders by the same special majority required to approve a compensation policy, provided that the insurance policy is on market terms and the insurance policy is not likely to materially impact the company’s profitability, assets or obligations. In addition, under regulations promulgated under the Companies Law, the insurance of office holders of a company in which there is a controlling shareholder who is also an office holder, a board approval is also required, subject to meeting the aforesaid conditions.

On December 5, 2024, the general meeting of our shareholders approved granting an indemnification and exemption letters to our officeholders and directors as may be from time to time, in the form previously approved by our shareholders. Indemnification letters, covering indemnification and insurance of those liabilities imposed under the Companies Law and the Securities Law, as discussed above, were granted to each of our officeholders and were approved for any future officeholders. All of our directors and the officers have executed indemnification letters.

The maximum indemnification amount set forth in such letters to all of our officeholders is limited to an amount equal to the higher of (i): $5,000,000; and (ii) 25% of our total shareholders’ equity, neutralizing a provision made for such indemnification, as reflected in our most recent financial statements (annual or quarterly) prior to the date on which the indemnity payment is made. The maximum amount set forth in such letters is in addition to any amount paid (if paid) under insurance and/or by a third party pursuant to an indemnification arrangement.

In the opinion of the SEC, indemnification of directors and officeholders for liabilities arising under the Securities Act, however, is against public policy and therefore unenforceable.

Exemption

Under the Companies Law, an Israeli company may not exempt an officeholder from liability for a breach of his or her duty of loyalty, but may exempt in advance an officeholder from his or her liability to the company, in whole or in part, for damages caused to the company as a result of a breach of his or her duty of care (other than in relation to distributions), but only if a provision authorizing such exemption is included in its articles of association. Our amended and restated articles of association provide that we may exempt, in whole or in part, any officeholder from liability to us for damages caused to the company as a result of a breach of his or her duty of care. Subject to the aforesaid limitations, under the indemnification agreements, we exempt and release our officeholders from any and all liability to us related to any breach by them of their duty of care to us to the fullest extent permitted by law.

Exemption letters were granted to each of our officeholders and were approved for any future officeholders.

Limitations

The Companies Law provides that we may not exempt or indemnify an officeholder nor enter into an insurance contract that would provide coverage for any liability incurred as a result of any of the following: (1) a breach by the officeholder of his or her duty of loyalty unless (in the case of indemnity or insurance only, but not exemption) the officeholder acted in good faith and had a reasonable basis to believe that the act would not prejudice us; (2) a breach by the officeholder of his or her duty of care if the breach was carried out intentionally or recklessly (as opposed to merely negligently); (3) an act committed with the intention of making a personal profit unlawfully; or (4) any fine, monetary sanction, penalty or forfeit levied against the officeholder.

Under the Companies Law, exemption, indemnification and insurance of officeholders in a public company must be approved by the compensation committee and the board of directors (and, with respect to directors and the chief executive officer, by the shareholders). However, under regulations promulgated under the Companies Law, the insurance of office holders shall not require shareholder approval and may be approved by only the compensation committee, if the engagement terms are determined in accordance with the company’s compensation policy that was approved by the shareholders by the same special majority required to approve a compensation policy, provided that the insurance policy is on market terms and the insurance policy is not likely to materially impact the company’s profitability, assets or obligations. In addition, under regulations promulgated under the Companies Law, the insurance of office holders of a company in which there is a controlling shareholder who is also an office holder, a board approval is also required, subject to meeting the aforesaid conditions.

Our amended and restated articles of association permit us to exempt (subject to the aforesaid limitation), indemnify and insure our officeholders to the fullest extent permitted or to be permitted by the Companies Law.

Item 10. Undertakings

(a)	The undersigned Registrant hereby undertakes:

(1)

To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i)

To include any prospectus required by section 10(a)(3) of the Securities Act of 1933;

(ii)

To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement.

(iii)

To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and a(l)(iii) do not apply if the registration statement is on Form S-3 or Form F-3 and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) To file a post-effective amendment to the registration statement to include any financial statements required by Item 8.A. of Form 20-F at the start of any delayed offering or throughout a continuous offering. Financial statements and information otherwise required by Section 10(a)(3) of the Act need not be furnished, provided, that the registrant includes in the prospectus, by means of a post-effective amendment, financial statements required pursuant to this paragraph (a)(4) and other information necessary to ensure that all other information in the prospectus is at least as current as the date of those financial statements. Notwithstanding the foregoing, with respect to registration statements on Form F-3, a post-effective amendment need not be filed to include financial statements and information required by Section 10(a)(3) of the Act or Rule 3-19 of this chapter if such financial statements and information are contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the Form F-3.

II-4

(5) That, for the purpose of determining liability under the Securities Act to any purchaser:

(i)

If the Registrant is relying on Rule 430B:

Each prospectus filed by the Registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(6) That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i)

Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii)

Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii)

The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv)

Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) 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 foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 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 Securities Act of 1933, as amended, and will be governed by the final adjudication of such issue.
