Sentiment and the balance of points

Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.

Rhea-AI Filing Summary

Purple Biotech Ltd. (PPBT) filed a pre-effective amendment to a replacement Form F-3 shelf covering a maximum aggregate offering price of USD 200,000,000. It covers ADSs representing ordinary shares, ordinary and preferred shares, warrants, overallotment purchase rights, subscription rights, units and/or capital notes. Sales may begin only after effectiveness, with specific terms set in prospectus supplements; no offering is presently contemplated. Net proceeds are intended for oncology-candidate development, new asset acquisitions and working capital, unless a supplement states otherwise.

While public float remains below USD 75.0 million, public primary sales in any 12-month period may not exceed one-third of public float; the stated amount is approximately USD 575,000. Purple Biotech also reports 691,806 ADSs sold or offered for approximately USD 2.3 million pursuant to the same public-float rule during the prior 12 calendar month period. Cash and short-term deposits were USD 6.105 million as of June 30, 2026. IM1240 and IM1305 are in preclinical development; the company expects to submit an IND application for IM1240 in 2027, subject to obtaining sufficient additional funding. Development of CM24 and NT219 has been discontinued, and subsidiaries initiated the process to terminate their license agreements in October 2026.

Maximum aggregate offering price USD 200,000,000 Shelf registration covering multiple security types.
Public float market value Approximately USD 1.7 million Aggregate market value of voting and non-voting common equity held by non-affiliates as of November 6, 2026.
Public-float-based 12-month sales amount Approximately USD 575,000 One-third limit while public float is below USD 75.0 million.

Cash and cash equivalents and short-term deposits USD 6.105 million As of June 30, 2026.
Expected IM1240 IND submission 2027 Expected subject to obtaining sufficient additional funding.
shelf registration process financial
"Under this shelf registration process, we may sell"
public float financial
"one-third of our outstanding voting and nonvoting common equity"
Public float is the total number of a company's shares that are available for trading by the general public. It excludes shares held by company insiders or large stakeholders who are unlikely to sell them easily. This figure helps investors understand how much of the company's stock is actively available, which can influence its liquidity and how easily its price might change.
at-the-market equity offering program financial
"acting as our agent under an “at-the-market” equity offering program"
A program that lets a company sell newly issued shares directly into the open market at whatever the current trading price is, usually through a broker, and do so gradually over time instead of all at once. Investors care because it can dilute existing ownership and put steady selling pressure on the stock price, while giving the company a flexible, on-demand way to raise cash — like adding small amounts of water to a pool rather than dumping in a bucket.
preclinical development medical
"IM1305, is in preclinical development"
Preclinical development is the stage where a potential drug, device, or therapy is tested in the lab and in animals to gather evidence on safety, how it works, and whether it’s worth trying in humans. Investors care because this phase creates early “proof” or warning signs about a candidate’s chances of success—similar to a prototype being stress-tested before production—so results strongly influence a project’s value, timeline, and risk.
IND application regulatory
"submit an IND application to the FDA for IM1240"
An Investigational New Drug (IND) application is a formal request to regulators to allow a drug or biologic to be tested in people. It bundles lab and animal safety data, manufacturing details, and a plan for human trials—think of it like a building permit that lets developers move from design to construction. For investors, IND approval is a key milestone that permits clinical testing, reduces regulatory uncertainty, and can materially affect a company’s timeline, risk profile, and valuation.
Offering Type shelf
Securities Offered ADSs representing ordinary shares, ordinary shares, preferred shares, warrants, overallotment purchase rights, subscription rights, units and/or capital notes
Offering Amount USD 200,000,000 maximum aggregate offering price
Use of Proceeds Net proceeds are intended to fund development of current and future oncology drug candidates, acquisition of new assets and general working capital, unless an applicable prospectus supplement indicates otherwise.

EXPLANATORY NOTE

 

This Pre-Effective Amendment No. 1 (this “Amendment”) to the Registration Statement on Form F-3 (File No. 333-296088) (the “Registration Statement”) of Purple Biotech Ltd. (the “Company”) is being filed to include updated disclosures since the Registration Statement was originally filed on May 20, 2026.

 

The Registration Statement is a replacement registration statement filed pursuant to Rule 415(a)(6) under the Securities Act of 1933, as amended (the “Securities Act”), with respect to securities which remain unsold under the Registration Statement on Form F-3 (File No. 333-268710) (the “Unsold Securities”) filed on December 8, 2022, and declared effective on May 22, 2023, which expired on May 22, 2026 (“Prior Registration Statement”). Pursuant to Rule 415(a)(5)(ii) under the Securities Act, by filing the Registration Statement, the Company may issue and sell securities under the Prior Registration Statement, including pursuant to the prospectus supplement to the base prospectus included in the Prior Registration Statement in connection with our existing At the Market Offering Agreement, dated September 19, 2025 (the “Sales Agreement”), with H.C. Wainwright & Co., LLC (“Wainwright”), until the earlier of the effective date of the Registration Statement or 180 days after May 22, 2026. In accordance with the terms of the Sales Agreement, we may offer and sell American Depositary Shares (“ADSs”) from time to time through Wainwright, acting as our agent under an “at-the-market” equity offering program (“ATM program”). We have sold an aggregate of 691,806 ADSs for gross proceeds of approximately USD 2.3 million pursuant to the Sales Agreement under the Prior Registration Statement. Pursuant to General Instruction I.B.5 of Form F-3, in no event will we sell securities registered on the Registration Statement of which any prospectus supplement forms a part in a public primary offering with a value exceeding one-third of our outstanding voting and nonvoting common equity held by non-affiliates (the “public float”) in any 12-month period so long as our public float remains below USD 75.0 million. As of the date of this prospectus, such amount is approximately USD 575,000. As of the date hereof, we have sold or offered 691,806 ADSs for a total of USD 2.3 million pursuant to General Instruction I.B.5 of Form F-3 during the prior 12 calendar month period that ends on and includes the date hereof.

The specific terms of any Shelf Securities to be offered pursuant to the base prospectus, including any ADSs to be offered, issued and sold under the Sales Agreement, will be specified in a prospectus supplement to the base prospectus.

Purple Biotech Ltd.

 

We may offer to the public from time to time in one or more series or issuances American Depositary Shares, or ADSs, ordinary shares, preferred shares, warrants, overallotment purchase rights, subscription rights, units and/or capital notes consisting of two or more of these classes or series of securities. Each ADS represents two thousand (2,000) of our ordinary shares.

 

We refer to the ADSs, ordinary shares, preferred shares, warrants, overallotment purchase rights, subscription rights, units and/or capital notes collectively as “securities” in this prospectus.

 

Each time we sell securities pursuant to this prospectus, we will provide a supplement to this prospectus that contains specific information about the offering and the specific terms of the securities offered. This prospectus may not be used to consummate a sale of securities by us unless accompanied by the applicable prospectus supplement. You should read this prospectus and the applicable prospectus supplement carefully before you invest in our securities.

 

We may, from time to time, offer to sell the securities, through public or private transactions, directly or through underwriters, agents or dealers, on or off The Nasdaq Capital Market or Tel Aviv Stock Exchange Ltd., or the TASE, as applicable, at prevailing market prices or at privately negotiated prices. If any underwriters, agents or dealers are involved in the sale of any of these securities, the applicable prospectus supplement will set forth the names of the underwriter, agent or dealer and any applicable fees, commissions or discounts.

 

Our ordinary shares are currently traded on the TASE under the symbol “PPBT.” The last reported sale price of our ordinary shares on the TASE on November 5, 2026 was NIS 0.01, or USD 0.00316, per share (based on the exchange rate reported by the Bank of Israel as of that date, which was NIS 3.167 = USD 1.00).

 

The ADSs are currently listed on The Nasdaq Capital Market under the symbol “PPBT”. The last reported sale price of the ADSs on The Nasdaq Capital Market on November 5, 2026 was USD 1.25.

 

On November 6, 2026, the aggregate market value worldwide of our outstanding voting and non-voting common equity held by non-affiliates was approximately USD 1.7 million, based on 3,192,189,312 ordinary shares outstanding held by non-affiliates (which would be represented by 1,596,095 of the ADSs) and a per ADS price of USD 1.08 based on the closing sale price of the ADS on The Nasdaq Capital Market on October 23, 2026. As of the date hereof, we have sold or offered 691,806 ADSs for a total of USD 2.3 million pursuant to General Instruction I.B.5 of Form F-3 during the prior 12 calendar month period that ends on and includes the date hereof.

Investing in these securities involves a high degree of risk.

ABOUT THIS PROSPECTUS

 

This prospectus is part of a registration statement that we filed with the Securities and Exchange Commission, or SEC, utilizing a “shelf” registration process. Under this process, we may offer and sell our securities under this prospectus.

 

Under this shelf registration process, we may sell the securities described in this prospectus in one or more offerings up to a total price to the public of USD 200,000,000. Furthermore, so long as the aggregate market value worldwide of our public float is less than USD 75 million, the aggregate market value of securities sold by us pursuant to this shelf registration statement during the period of 12 calendar months immediately prior to, and including, the sale, shall be no more than one-third of the public float. The offer and sale of securities under this prospectus may be made from time to time, in one or more offerings, in any manner described under the section in this prospectus entitled “Plan of Distribution.” This shelf registration statement is not being filed by us in connection with any presently contemplated securities offering.

 

This prospectus provides you with a general description of the securities we may offer. Each time we sell securities we will provide a prospectus supplement that will contain specific information about the terms of that offering. The prospectus supplement may also add, update or change information contained in this prospectus, and may also contain information about any material federal income tax considerations relating to the securities covered by the prospectus supplement. You should read both this prospectus and any prospectus supplement together with additional information under the headings “Where You Can Find Additional Information” and “Incorporation of Certain Documents by Reference.”

 

On September 19, 2025, we entered into an At the Market Offering Agreement (the “Sales Agreement”), with H.C. Wainwright & Co., LLC (“Wainwright”), for the sale of ADSs, representing our ordinary shares offered by the prospectus supplement filed on September 19, 2025 and the accompanying prospectus. In accordance with the terms of the Sales Agreement, we may offer and sell ADSs from time to time through Wainwright, acting as our agent. We have sold an aggregate of 691,806 ADSs for gross proceeds of approximately USD 2.3 million pursuant to the Sales Agreement under our registration statement on Form F-3 (File No. 333-268710), of which 607,982 ADSs for gross proceeds of approximately USD 1.9 million were sold after May 22, 2026, the date such registration statement expired, in reliance on Rule 415(a)(5)(ii) under the Securities Act of 1933, as amended (the “Securities Act”). Any future sales of ADSs under the Sales Agreement pursuant to this registration statement will be made pursuant to a prospectus supplement to this prospectus, subject to the limitations of General Instruction I.B.5 of Form F-3.

 

For investors outside of the United States: We have not done anything that would permit this offering or possession or distribution of this prospectus in any jurisdiction where action for that purpose is required, other than in the United States.

PROSPECTUS SUMMARY

 

This summary highlights selected information about us and information contained in greater detail elsewhere in this prospectus and in the documents incorporated by reference herein. This summary is not complete and does not contain all of the information that you should consider before investing in our securities. You should carefully read and consider this entire prospectus and the documents, including financial statements and related notes, and information incorporated by reference into this prospectus, including the financial statements and “Risk Factors” starting on page 7 of this prospectus, before making an investment decision. If you invest in our securities, you are assuming a high degree of risk.

 

The Company

 

We are a biotechnology company developing a next-generation immunotherapy platform designed to maximize anti-cancer potency while minimizing toxicity.

 

We are focused on advancing CAPTN-3, which is a platform of masked tri-specific antibodies that simultaneously target tumors while engaging both T cells and NK cells. Capping technology is designed to confine immune activation to the tumor microenvironment (“TME”) and, based on preclinical data, to expand the therapeutic window compared with unmasked T-cell engagers. The platform’s lead candidate, IM1240, is advancing toward the clinic and its second candidate, IM1305, is in preclinical development.

 

The technology utilized by CAPTN-3 presents a novel mechanism of action by unleashing both innate and adaptive immune responses at the TME to induce a broad anti-tumor immune response. The platform’s lead candidate, IM1240 (capped-CD3x5T4xNKG2A), and its second candidate, IM1305 (capped-CD3xTROP2xNKG2A), are in preclinical development. IM1240 targets the 5T4 tumor-associated antigen, which is expressed in a variety of solid tumors and is associated with advanced disease, increased invasiveness, and poor clinical outcomes. Preclinical studies of IM1240 have shown sustained tumor regression in a triple-negative breast cancer in-vivo model and pronounced anti-tumor effects in non-small cell lung cancer and head and neck cancer patient-derived explants. A preclinical toxicology study showed a favorable safety and pharmacokinetic profile for IM1240. In-vivo and in-vitro data demonstrated the platform’s plug-and-play capability and a potentially beneficial safety profile. In April 2024, in response to our pre-Investigational New Drug (“IND”) (Type B) meeting request for IM1240, we received written responses from the United States Food and Drug Administration (“FDA”), and in February 2026 we received the FDA’s written responses to a Type C meeting request. Subject to obtaining sufficient additional funding, we expect to submit an IND application to the FDA for IM1240 during 2027 and to initiate a first-in-human study thereafter. IM1305 targets the TROP2 tumor-associated antigen. As previously disclosed, further development of our former clinical-stage assets, CM24 and NT219, had been pending partnering or investment, and we wrote off the carrying value of the related in-process research and development as of December 31, 2025. We have since discontinued development of CM24 and NT219, and in October 2026, our subsidiaries initiated the process to terminate each of the NT219 license agreement and the CM24 license agreement.

SUMMARY OF RISK FACTORS

 

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 included under the caption “Risk Factors” on page 7 of this prospectus, and certain other matters discussed in this prospectus and the information incorporated by reference herein.

 

 

●

We are a preclinical stage biotechnology company with a history of operating losses. We expect to incur significant additional losses in the future and may never be profitable;

 

 

●

Our limited operating history as a biotechnology research and development company makes it difficult to evaluate our business and prospects, and we depend substantially on the success of our CAPTN-3 platform, including our lead candidate IM1240, which remains in preclinical development, for our future revenue, which could impair our ability to achieve profitability;

 

 

●

We have discontinued development of CM24 and NT219 and have initiated the process to terminate the related license agreements, and we may not realize any further value from these programs;

 

 

●

We will need to raise additional capital to achieve our strategic objectives of developing and commercializing our therapeutic candidates, and to develop, acquire and/or in-license additional therapeutic candidates, and our failure to raise sufficient capital would significantly impair our ability to fund our future operations, develop our current or future therapeutic candidates, seek regulatory approval that is a prerequisite to selling any product, attract development or commercial partners, and retain key personnel;

 

 

●

Our long-term capital requirements are uncertain and subject to numerous risks;

 

 

●

Our clinical trials may fail to demonstrate adequately the safety and efficacy of our therapeutic candidates, which would prevent or delay regulatory approval and commercialization;

 

 

●

Regulations are constantly changing, and in the future our business may be subject to additional regulations that could increase our compliance costs or delay our ability to market our product candidates, if at all;

 

 

●

Our therapeutic candidates may cause undesirable side effects or have other properties that could halt clinical development, prevent regulatory approval, limit commercial potential, or result in significant negative consequences;

 

 

●

If we and/or our potential commercialization partners are unable to obtain FDA and/or other foreign regulatory authority approval for our therapeutic candidates, we and/or our potential commercialization partners, will be unable to commercialize our therapeutic candidates;

 

 

●

Preclinical studies, chemistry, manufacturing and controls (“CMC”), and clinical trials may involve a lengthy and expensive process with an uncertain outcome, and the results of earlier studies and trials may not be predictive of future results. We and/or our potential commercialization partners will not be able to commercialize our therapeutic candidates unless we satisfactorily meet the requirements set by regulatory agencies for CMC, preclinical and clinical studies, and obtain regulatory approval, for marketing therapeutic candidates;

 

 

●

If we do not establish collaborations for our oncology therapeutic candidates or any other therapeutic candidates that we may develop or acquire in the future and/or commercialize such therapeutic candidates, or otherwise raise substantial additional capital, we will likely need to alter our development and any commercialization plans;

 

 

●

Any collaborative arrangements that we establish may not be successful or we may otherwise not realize the anticipated benefits from these collaborations. We do not control third parties with whom we have or may have collaborative arrangements, and we rely on them to achieve results which may be significant to us. In addition, any future collaboration arrangements may place the development, manufacturing and commercialization of our oncology therapeutic candidates or any other therapeutic candidates that we may develop or acquire in the future, outside our control, and may require us to relinquish important rights or may otherwise be on terms unfavorable to us;

 

4

 

 

 

 

●

We rely mainly on third parties to conduct our CMC, research and development, preclinical studies and clinical trials, and those third parties may not perform satisfactorily, including, but not limited to, failing to conform with quality standards for our therapeutic candidates, which may endanger our clinical trial participants and/or fail to meet established deadlines for the completion of such studies and trials;

 

 

●

If third parties do not manufacture our current therapeutic candidates or any other therapeutic candidate that we may develop or acquire in the future in sufficient quantities in the required timeframe, at the required quality standards and at an acceptable cost, preclinical, clinical development and commercialization of our therapeutic candidates could be delayed;

 

 

●

We rely on third-party contract vendors to manufacture and supply us with active pharmaceutical ingredients that are compliant with the International Conference of Harmonization Q7 guidance and other applicable laws and regulations, in the quality and quantities we require on a timely basis;

 

 

●

We anticipate continued reliance on third-party manufacturers if we are successful in obtaining marketing approval from the FDA and/or other regulatory agencies for IM1240 and IM1305, or any other therapeutic candidates we may develop or acquire in the future;

 

 

●

We and our third-party manufacturers are, and will be, subject to regulations of the FDA and other foreign regulatory authorities;

 

 

●

Our oncology therapeutic candidates and/or any other therapeutic candidate that we may develop or acquire in the future, if approved, will be subject to ongoing regulatory review. If we fail to comply with continuing U.S. and applicable foreign laws, regulations and guidelines, we could lose the FDA and/or other regulatory agencies’ approval(s) we will obtain (if any), and our business would be seriously harmed;

 

 

●

We may depend on a partner to conduct future clinical trials with our therapeutic candidates, and we may enter into future collaboration agreements with collaboration partners to develop and conduct clinical trials with, obtain regulatory approvals for, and to market and sell our therapeutic candidates. If such collaboration fails to perform as expected, our future clinical trials and/or development plans will be delayed, and we will be required to seek other partners, which we may not be able to engage in a timely manner, if at all, and which may delay our development plans and therefore the potential for us to generate future revenue from our therapeutic candidates would be significantly reduced and our business would be significantly harmed;

 

 

●

The manufacture of our therapeutic candidates is complex, and we may encounter difficulties in production, particularly with respect to process development or scaling-up of our manufacturing capabilities. If we, or any of our third-party manufacturers, encounter such difficulties, our ability to supply drugs for clinical trials or our products (if approved) for patients on a timely basis could be materially delayed or adversely affected. In addition, this may cause an increase in costs that could result in our inability to maintain a commercially viable cost structure;

 

5

 

 

 

 

●

Because each of our therapeutic candidates represents a novel approach to the treatment of disease, there are many uncertainties regarding the development, the market acceptance, third-party reimbursement coverage and the commercial potential of these therapeutic candidates;

 

 

●

If we fail to comply with any obligations under any current or future license agreement or acquisition agreements of our therapeutic candidates, or disputes arise with respect to those agreements, it could have a negative impact on our intellectual property rights and we could lose our rights to IM1240, IM1305 or any further therapeutic candidates, which could have a material adverse effect on our business, financial condition and results of operations;

 

 

●

Our shareholders may not realize a benefit from our acquisitions of therapeutic candidates commensurate with the ownership dilution they experienced in connection with the transactions;

 

 

●

Any impairment in the value of our intangible assets, including goodwill, could negatively affect our operating results and total capitalization;

 

 

●

The markets for our oncology therapeutic candidates are rapidly changing and competitive, and new drug delivery mechanisms, drug delivery technologies, new drugs and new treatments which may be developed by others could impair our ability to maintain and grow our business and remain competitive;

 

 

●

Our business and operations may be materially adversely affected in the event of computer system failures or security or breaches due to cyber-attacks or cyber intrusions, including ransomware, phishing attacks and other malicious intrusions;

 

 

●

Third-party claims of intellectual property infringement and other legal challenges may require us to spend substantial time and money and could prevent us from, or delay us in, developing or commercializing our therapeutic candidates. An adverse result in any infringement claims or other legal challenges could have a material adverse effect on our business, results of operations and on our financial condition;

 

 

●

We may be unable to adequately protect or enforce our rights to intellectual property, causing us to lose valuable rights. Loss of any of our intellectual property rights may lead us to lose market share and could have an adverse effect on our business, results of operations and financial condition;

 

 

●

We may not have sufficient patent terms to effectively protect our products and business;

 

 

●

We conduct our operations in Israel, and therefore, political, economic and military instability in Israel and its region may adversely affect our business, results of operations, and financial condition; and

 

 

●

We may not meet the continued listing requirements of Nasdaq, which could result in the delisting of the ADSs from Nasdaq.

DESCRIPTION OF ORDINARY SHARES

 

A description of our Ordinary Shares can be found in Exhibit 2.1, Description of Share Capital, to our Annual Report on Form 20-F for the year ended December 31, 2025, filed with the SEC on March 19, 2026.

 

Exclusive Forum for Shareholder Litigation

 

Our amended and restated articles of association provide that, unless we consent in writing to the selection of an alternative forum, the Tel Aviv District Court (Economic Division) in the State of Israel (or, if the Tel Aviv District Court does not have jurisdiction, and no other Israeli court has jurisdiction, the federal district court for the District of New York) shall be the sole and exclusive forum for (1) any derivative action or proceeding brought on our behalf, (2) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers or other employees to us or our shareholders, and (3) any action asserting a claim arising pursuant to any provision of the Companies Law or the Israeli Securities Law 5728-1968, in all cases subject to the court’s having personal jurisdiction over the indispensable parties named as defendants. In addition, unless we consent in writing to the selection of an alternative forum, and other than with respect to plaintiffs or a class of plaintiffs which may be entitled to assert claims in the courts of the State of Israel with respect to any causes of action arising under the Securities Act, the federal district courts of the United States for the District of New York shall be the exclusive forum for any complaint asserting a cause of action arising under the Securities Act. Any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock shall be deemed to have notice of and consented to these provisions. This forum selection provision will limit shareholders’ choice in selecting a judicial forum for disputes with us that it finds favorable or convenient and may have the effect of discouraging lawsuits against us or our directors and officers.

Share History

 

The following is a summary of the history of our share capital for the last three years.

On July 2, 2024, we raised USD 2 million in gross proceeds (approximately USD 1.8 million net of placement agent fees) in a warrant inducement transaction. In this transaction, we induced the exercise of certain existing warrants to purchase an aggregate of 28,168 ADSs, of which 16,647 ADSs were held in abeyance. The existing warrants had original exercise prices ranging from USD 250 to USD 4,000 per ADS and were originally issued by us in October 2023, June 2020, January 2019 and June 2018. The exercise price for these existing warrants was reduced to USD 72 per ADS. As of December 31, 2025, no ADSs are held in abeyance.

 

In consideration for the exercise of the existing warrants, we issued new unregistered Series A-1 warrants to purchase up to an aggregate of 24,897 ADSs and new unregistered Series A-2 warrants to purchase up to an aggregate of 31,438 ADSs. The new warrants are immediately exercisable at an exercise price of USD 80.0 per ADS. The Series A-1 warrants have a term of five years from the issuance date, and the Series A-2 warrants had a term of twenty-four months from the issuance date.

In total during 2024, an aggregate of approximately 38,000 ADSs were issued as a result of the exercise of warrants and pre-funded warrants.

 

On December 5, 2024, in a registered direct offering, we raised USD 2.83 million in gross proceeds (approximately USD 2.5 million net of placement agent fees). In this registered direct offering, we issued an aggregate of 47,267 ADSs at a purchase price of USD 60.0 per ADS. In addition, we issued to the placement agent (or its designees) unregistered compensation warrants to purchase up to 3,309 ADSs at an exercise price of USD 75 per ADS. The unregistered placement agent warrants are immediately exercisable and have a term of five years, expiring on December 3, 2029.

 

During 2024, we issued 3,142,000 ordinary shares on account of vested restricted share units (“RSUs”) granted in 2021, 2022 and 2023 to officers, board members and employees.

 

On September 5, 2025, we completed a public offering pursuant to an effective registration statement on Form F-1. In this offering, we issued an aggregate of 305,500 ADSs and pre-funded warrants to purchase up to 294,500 ADSs (of which 188,500 were exercised prior to the closing) at an offering price of USD 10.00 per ADS and USD 9.999 per pre-funded warrant, each accompanied by ordinary warrants. The offering generated aggregate gross proceeds of approximately USD 6.0 million (approximately USD 5.3 million net of placement agent fees and offering expenses). In addition, we issued twenty-four month warrants to purchase up to 1,200,000 ADSs at an exercise price of USD 10.00 per ADS. The warrants are immediately exercisable and expire two years from the closing date. The pre-funded warrants had an exercise price of USD 0.001 per ADS and have all been exercised. In connection with the offering, we issued to the placement agent warrants to purchase up to 42,000 ADSs at an exercise price of USD 12.50 per ADS. The placement agent warrants are immediately exercisable and expire on September 7, 2027.

 

During 2025, an aggregate of approximately 132,000 ADSs were issued as a result of the exercise of warrants and pre-funded warrants.

Pursuant to the September 2025 Investor Warrants, if at the time of exercise a registration statement registering the issuance of the ADSs underlying the warrants under the Securities Act is not then effective or available, the holder may exercise the warrants through a cashless exercise, in whole or in part, in which case the holder would receive upon such exercise the net number of ADSs determined according to the formula set forth in the warrants.

 

We also issued registered warrants to purchase up to 42,000 ADSs, representing 84,000,000 of our ordinary shares, to Wainwright (or its designees), the exclusive placement agent for the September 2025 offering (the “September 2025 PA Warrants”).

DESCRIPTION OF UNITS

 

We may issue units comprised of one or more of the other securities that may be offered under this prospectus, in any combination. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately at any time, or at any time before a specified date.

 

The prospectus supplement relating to any units we offer, if any, will, to the extent applicable, include specific terms relating to the offering, including some or all of the following:

 

 

●

the material terms of the units and of the securities comprising the units, including whether and under what circumstances those securities may be held or transferred separately;

 

 

 

 

●

any material provisions relating to the issuance, payment, settlement, transfer or exchange of the units or of the securities comprising the units; and

 

 

 

 

●

any material provisions of the governing unit agreement that differ from those described above.

 

The description in the applicable prospectus supplement of any units we offer will not necessarily be complete and will be qualified in its entirety by reference to the applicable unit agreement, which will be filed with the SEC if we offer units. For more information on how you can obtain copies of the applicable unit agreement if we offer units, see “Where You Can Find Additional Information” beginning on page 22 of this prospectus and “Incorporation of Certain Documents by Reference” beginning on page 24 of this prospectus. We urge you to read the applicable unit agreement and any applicable prospectus supplement in their entirety.

DESCRIPTION OF CAPITAL NOTES

 

We may from time to time offer and sell under this prospectus capital notes, referred to herein as equity equivalent capital notes. When we offer to sell a particular series of capital notes, we will describe the specific terms of the series in a prospectus supplement. We will also indicate in the prospectus supplement whether the general terms and provisions described in this prospectus apply to a particular series of capital notes.

 

The capital notes are instruments of equity and not debt. Unless otherwise specified in a prospectus supplement, (i) the face amounts of the capital notes will not bear interest nor will they be linked to any index, (ii) the face amounts of the capital notes will only be payable by us out of distributions made upon the winding-up, liquidation or dissolution of our company on a pari passu and pro rata basis with the holders of our ordinary shares and (iii) we will have no right to prepay or redeem the equity equivalent capital notes. In addition, the holder may at any time, convert the face amount of the equity equivalent capital notes, in whole or in part, without payment of any additional consideration, into ADSs or ordinary shares, as set forth in the equity equivalent capital note, at a conversion price agreed with the holder. Unless otherwise specified in a prospectus supplement, the equity equivalent capital notes shall have no maturity date and the right to convert into ADSs or ordinary shares shall not expire.

 

The terms of any particular series of equity equivalent capital notes will be set forth in the purchase agreement with the purchasers and the governing capital note certificate, each of which will be incorporated by reference as an exhibit to the registration statement of which this prospectus forms a part. The foregoing summary of the equity equivalent capital notes is not complete. We encourage you to read the purchase agreement and capital note certificate, because they, and not this summary, will govern your rights as a holder of equity equivalent capital notes.

The material Israeli and U.S. federal income tax consequences relating to the purchase, ownership and disposition of any of the securities offered by this prospectus will be set forth in the prospectus supplement offering those securities.

At any time a particular offer of the securities covered by this prospectus is made, a revised prospectus or prospectus supplement, if required, will be distributed which will set forth the aggregate amount of securities covered by this prospectus being offered and the terms of the offering, including the name or names of any underwriters, dealers, brokers or agents, any discounts, commissions, concessions and other items constituting compensation from us and any discounts, commissions or concessions allowed or re-allowed or paid to dealers. Such prospectus supplement, and, if necessary, a post-effective amendment to the registration statement of which this prospectus is a part, will be filed with the SEC to reflect the disclosure of additional information with respect to the distribution of the securities covered by this prospectus. In order to comply with the securities laws of certain states, if applicable, the securities sold under this prospectus may only be sold through registered or licensed broker-dealers. In addition, in some states the securities may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from registration or qualification requirements is available and is complied with.

 

18

 

 

 

The distribution of securities may be effected from time to time in one or more transactions, including block transactions and transactions on The Nasdaq Capital Market or any other organized market where the securities may be traded. The securities may be sold at a fixed price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices relating to the prevailing market prices or at negotiated prices. The consideration may be cash or another form negotiated by the parties. Agents, underwriters or broker-dealers may be paid compensation for offering and selling the securities. That compensation may be in the form of discounts, concessions or commissions to be received from us or from the purchasers of the securities. Any dealers and agents participating in the distribution of the securities may be deemed to be underwriters, and compensation received by them on resale of the securities may be deemed to be underwriting discounts. If any such dealers or agents were deemed to be underwriters, they may be subject to statutory liabilities under the Securities Act.

 

Agents may from time to time solicit offers to purchase the securities. If required, we will name in the applicable prospectus supplement any agent involved in the offer or sale of the securities and set forth any compensation payable to the agent. Unless otherwise indicated in the prospectus supplement, any agent will be acting on a best efforts basis for the period of its appointment. Any agent selling the securities covered by this prospectus may be deemed to be an underwriter, as that term is defined in the Securities Act, of the securities.

 

To the extent that we make sales to or through one or more underwriters or agents in at-the-market offerings, we will do so pursuant to the terms of a distribution agreement between us and the underwriters or agents. If we engage in at-the-market sales pursuant to a distribution agreement, we will sell any of our listed securities to or through one or more underwriters or agents, which may act on an agency basis or on a principal basis. During the term of any such agreement, we may sell any of our listed securities on a daily basis in exchange transactions or otherwise as we agree with the underwriters or agents. The distribution agreement will provide that any of our listed securities which are sold will be sold at prices related to the then prevailing market prices for our listed securities. Therefore, exact figures regarding proceeds that will be raised or commissions to be paid cannot be determined at this time and will be described in a prospectus supplement. Pursuant to the terms of the distribution agreement, we also may agree to sell, and the relevant underwriters or agents may agree to solicit offers to purchase, blocks of our listed securities. The terms of each such distribution agreement will be set forth in more detail in a prospectus supplement to this prospectus.

 

If underwriters are used in a sale, securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale, or under delayed delivery contracts or other contractual commitments. Securities may be offered to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. If an underwriter or underwriters are used in the sale of securities, an underwriting agreement will be executed with the underwriter or underwriters, as well as any other underwriter or underwriters, with respect to a particular underwritten offering of securities, and will set forth the terms of the transactions, including compensation of the underwriters and dealers and the public offering price, if applicable. The prospectus and prospectus supplement will be used by the underwriters to resell the securities.

 

If a dealer is used in the sale of the securities, we or an underwriter will sell the securities to the dealer, as principal. The dealer may then resell the securities to the public at varying prices to be determined by the dealer at the time of resale. To the extent required, we will set forth in the prospectus supplement the name of the dealer and the terms of the transactions.

 

We may directly solicit offers to purchase the securities and may make sales of securities directly to institutional investors or others. These persons may be deemed to be underwriters within the meaning of the Securities Act with respect to any resale of the securities. To the extent required, the prospectus supplement will describe the terms of any such sales, including the terms of any bidding or auction process, if used.

 

19

 

 

 

Agents, underwriters and dealers may be entitled under agreements which may be entered into with us to indemnification by us against specified liabilities, including liabilities incurred under the Securities Act, or to contribution by us to payments they may be required to make in respect of such liabilities. If required, the prospectus supplement will describe the terms and conditions of the indemnification or contribution. Some of the agents, underwriters or dealers, or their affiliates may be customers of, engage in transactions with or perform services for us or our subsidiaries.

 

Any person participating in the distribution of securities registered under the registration statement that includes this prospectus will be subject to applicable provisions of the Securities Exchange Act of 1934, as amended, or the Exchange Act, and the applicable SEC rules and regulations, including, among others, Regulation M, which may limit the timing of purchases and sales of any of our securities by that person. Furthermore, Regulation M may restrict the ability of any person engaged in the distribution of our securities to engage in market-making activities with respect to our securities. These restrictions may affect the marketability of our securities and the ability of any person or entity to engage in market-making activities with respect to our securities.

 

Certain persons participating in an offering may engage in over-allotment, stabilizing transactions, short-covering transactions, penalty bids and other transactions that stabilize, maintain or otherwise affect the price of the offered securities. These activities may maintain the price of the offered securities at levels above those that might otherwise prevail in the open market, including by entering stabilizing bids, effecting syndicate covering transactions or imposing penalty bids, each of which is described below:

 

 

●

A stabilizing bid means the placing of any bid, or the effecting of any purchase, for the purpose of pegging, fixing or maintaining the price of a security.

 

 

 

 

●

A syndicate covering transaction means the placing of any bid on behalf of the underwriting syndicate or the effecting of any purchase to reduce a short position created in connection with the offering.

 

 

 

 

●

A penalty bid means an arrangement that permits the managing underwriter to reclaim a selling concession from a syndicate member in connection with the offering when offered securities originally sold by the syndicate member are purchased in syndicate covering transactions.

 

These transactions may be effected on an exchange or automated quotation system, if the securities are listed on that exchange or admitted for trading on that automated quotation system, or in the over-the-counter market or otherwise.

 

If so indicated in the applicable prospectus supplement, we will authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase offered securities from us at the public offering price set forth in such prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. Such contracts will be subject only to those conditions set forth in the prospectus supplement and the prospectus supplement will set forth the commission payable for solicitation of such contracts.

 

In addition, ordinary shares, preferred shares, or ADSs may be issued upon conversion of other securities.

 

20

 

 

 

Any underwriters to whom offered securities are sold for public offering and sale may make a market in such offered securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice. The offered securities may or may not be listed on a national securities exchange. No assurance can be given that there will be a market for the offered securities.

 

Any securities that qualify for sale pursuant to Rule 144 or Regulation S under the Securities Act, may be sold under Rule 144 or Regulation S rather than pursuant to this prospectus.

 

To the extent that we make sales to or through one or more underwriters or agents in at-the-market offerings, we will do so pursuant to the terms of a distribution agreement between us and the underwriters or agents. If we engage in at-the-market sales pursuant to a distribution agreement, we will sell our ordinary shares, preferred shares, or ADSs to or through one or more underwriters or agents, which may act on an agency basis or on a principal basis. During the term of any such agreement, we may sell ordinary shares, preferred shares, or ADSs on a daily basis in exchange transactions or otherwise as we agree with the underwriters or agents. The distribution agreement will provide that any ordinary shares, preferred shares, or ADSs sold will be sold at prices related to the then prevailing market prices for our ordinary shares, preferred shares, or ADSs. Therefore, exact figures regarding proceeds that will be raised or commissions to be paid cannot be determined at this time and will be described in a prospectus supplement. Pursuant to the terms of the distribution agreement, we also may agree to sell, and the relevant underwriters or agents may agree to solicit offers to purchase, blocks of our ordinary shares, preferred shares, ADSs or warrants. The terms of each such distribution agreement will be set forth in more detail in a prospectus supplement to this prospectus.

 

In connection with offerings made through underwriters or agents, we may enter into agreements with such underwriters or agents pursuant to which we receive our outstanding securities in consideration for the securities being offered to the public for cash. In connection with these arrangements, the underwriters or agents may also sell securities covered by this prospectus to hedge their positions in these outstanding securities, including in short sale transactions. If so, the underwriters or agents may use the securities received from us under these arrangements to close out any related open borrowings of securities.

 

We may enter into derivative transactions with third parties or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, such third parties (or affiliates of such third parties) may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, such third parties (or affiliates of such third parties) may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of shares, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of shares. The third parties (or affiliates of such third parties) in such sale transactions will be underwriters and will be identified in the applicable prospectus supplement (or a post-effective amendment).

 

We may loan or pledge securities to a financial institution or other third party that in turn may sell the securities using this prospectus. Such financial institution or third party may transfer its short position to investors in our securities or in connection with a simultaneous offering of other securities offered by this prospectus.

WHERE YOU CAN FIND ADDITIONAL INFORMATION

 

We have filed with the SEC a registration statement on Form F-3 under the Securities Act relating to the offering of our securities offered hereby. This prospectus does not contain all of the information contained in the registration statement. The rules and regulations of the SEC allow us to omit certain information from this prospectus that is included in the registration statement. Statements made in this prospectus concerning the contents of any contract, agreement or other document are summaries of all material information about the documents summarized, but are not complete descriptions of all terms of these documents. If we filed any of these documents as an exhibit to the registration statement, you may read the document itself for a complete description of its terms.

 

We are required to file reports and other information with the SEC under the Exchange Act, and the regulations thereunder applicable to foreign private issuers. The SEC maintains an Internet site that contains reports and other information regarding issuers that file electronically with the SEC. Our filings with the SEC are available to the public through this website at http://www.sec.gov. For so long as we are also listed on the TASE, these SEC filings are also generally available to the public on (i) the Israel Securities Authority’s Magna website at www.magna.isa.gov.il, (ii) the Tel Aviv Stock Exchange website at http://www.maya.tase.co.il, and (iii) from commercial document retrieval services.

 

As a foreign private issuer, we are exempt from the rules under the Exchange Act relating to the furnishing and content of proxy statements. In addition, our officers, directors and principal shareholders are exempt from the short-swing profit recovery provisions contained in Section 16(b) of the Exchange Act and our principal shareholders are exempt from the reporting obligations contained in Section 16(a) of the Exchange Act. We are not required under the Exchange Act to file periodic reports and financial statements with the SEC as frequently or as promptly as U.S. companies whose securities are registered under the Exchange Act. However, we are required to file with the SEC, within 120 days after the end of each fiscal year ending December 31, an annual report on Form 20-F containing financial statements which are examined and reported on, with an opinion expressed, by an independent registered public accounting firm. We also furnish to the SEC under cover of Form 6-K material information required to be made public in Israel, filed with and made public by any stock exchange or distributed by us to our shareholders. In addition, in accordance with the Nasdaq Listing Rules, as a foreign private issuer we are required to submit on Form 6-K an interim balance sheet and income statement as of the end of the second quarter of each fiscal year. We have also agreed contractually under the Sales Agreement for our ATM program to submit to the SEC, on Form 6-K, an interim balance sheet and income statement as of the end of the first and/or third quarters of each fiscal year if we shall desire to sell ADSs pursuant to the Sales Agreement during certain time periods.

 

We maintain a corporate website at www.purple-biotech.com. Information contained on, or that can be accessed through, our website does not constitute a part of this prospectus. We have included our website address in this prospectus solely as an inactive textual reference. We will post on our website any materials required to be posted on such website under applicable corporate or securities laws and regulations.

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 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.

 

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, 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 which can be a time-consuming and costly process. Certain matters of procedure will also be governed by Israeli law.

 

Subject to certain time limitations and legal procedures, Israeli courts may enforce a United States 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:

 

 

●

the judgment was rendered by a court which was, according to the laws of the state of the court, competent to render the judgment;

 

 

●

the obligation imposed by the judgment is enforceable according to the rules relating to the enforceability of judgments in Israel and the substance of the judgment is not contrary to public policy; and

 

 

●

the judgment is executory in the state in which it was given.

 

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

 

 

●

the judgment was given in a state whose laws do not provide for the enforcement of judgments of Israeli courts (subject to exceptional cases);

 

 

●

the enforcement of the judgment is likely to prejudice the sovereignty or security of the State of Israel;

 

 

●

the judgment was obtained by fraud;

 

 

●

the opportunity given to the defendant to bring its arguments and evidence before the court was not reasonable in the opinion of the Israeli court;

 

 

●

the judgment was rendered by a court not competent to render it according to the laws of private international law as they apply in Israel;

 

 

●

the judgment is contradictory to another judgment that was given in the same matter between the same parties and that is still valid; or

 

 

●

at the time the action was brought in the foreign court, a lawsuit in the same matter and between the same parties was pending before a court or tribunal in Israel.

 

We have irrevocably appointed Puglisi & Associates, 850 Library Avenue, Suite 204, Newark, DE 19715 Tel: +1 (302) 738-6680 as our agent to receive service of process in any action against us in any United States federal or state court arising out of this offering or any purchase or sale of securities in connection with this offering.

 

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

Pursuant to Rule 415(a)(6) under the Securities Act, a portion of the filing fee in the amount of USD 14,192.04 relates to USD 182,134,435.47 of securities which remain unsold (the “Unsold Securities”) under the Registration Statement on Form F-3 (File No. 333-268710) filed on December 8, 2022, and declared effective on May 22, 2023 (the “Prior Registration Statement”). We previously carried forward a registration fee of USD 15,584.14 in connection with the filing of the Prior Registration Statement of which USD 14,192.04 relates to the Unsold Securities. The USD 14,192.04 previously paid filing fee relating to such Unsold Securities under the Prior Registration Statement will continue to be applied to such Unsold Securities registered on this registration statement. For reasons stated above, the net SEC registration fee paid in connection with this registration statement is USD 2,349.71. The estimates do not include expenses related to offerings of particular securities. Each prospectus supplement describing an offering of securities will reflect the estimated expenses related to the offering of securities under that prospectus supplement.

Item 8. Indemnification of Directors and Officers

 

Under the Companies Law, a company may not exculpate an office holder from liability for a breach of a 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 amended and restated articles of association include such a provision. The company may not exculpate in advance a director from liability arising out of breach of duty of care with respect to a prohibited dividend or distribution to shareholders.

 

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

 

 

●

a monetary liability incurred by or imposed on an office holder in favor of another person pursuant to a judgment, including a settlement or arbitrator’s award approved by a court. However, if an undertaking to indemnify an office holder with respect to such liability is provided in advance, then such an undertaking must be limited to events which, in the opinion of the board of directors, can be foreseen based on the company’s activities when the undertaking to indemnify is given, and to an amount or according to criteria determined by the board of directors as reasonable under the circumstances, and such undertaking shall detail the abovementioned foreseen events and amount or criteria;

 

 

●

reasonable litigation expenses, including reasonable attorneys’ fees, incurred by the office holder as a result of an investigation or proceeding instituted against an office holder by an authority authorized to conduct such investigation or proceeding, provided that (i) no indictment was filed against such office holder as a result of such investigation or proceeding; and (ii) no financial liability was imposed upon such office holder as a substitute for the criminal proceeding 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 in connection with a monetary sanction;

 

 

●

a monetary liability imposed on an office holder in favor of a payment for a breach offended at an Administrative Procedure (as defined below) as set forth in Section 52(54)(a)(1)(a) to the Securities Law;

 

 

●

expenses associated with an Administrative Procedure conducted regarding an office holder, including reasonable litigation expenses and reasonable attorneys’ fees; and

 

 

●

reasonable litigation expenses, including attorneys’ fees, incurred by the office holder or imposed by a court in proceedings instituted against an office holder by the company, on its behalf, or by a third-party, or in connection with criminal proceedings in which the office holder was acquitted, or as a result of a conviction for an offense that does not require proof of criminal intent.

 

II-1

 

 

 

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 in its capacity as an office holder if and to the extent provided in the company’s articles of association:

 

 

●

a breach of a fiduciary duty to the company, provided that the office holder acted in good faith and had a reasonable basis to believe that the act would not harm the company;

 

 

●

a breach of duty of care to the company or to a third-party, to the extent such a breach arises out of the negligent conduct of the office holder;

 

 

●

a monetary liability imposed on the office holder in favor of a third-party;

 

 

●

a monetary liability imposed on the office holder in favor of an injured party at an Administrative Procedure pursuant to Section 52(54)(a)(1)(a) of the Securities Law; and

 

 

●

expenses incurred by an office holder in connection with an Administrative Procedure, including reasonable litigation expenses and reasonable attorneys’ fees.

 

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

 

 

●

a breach of fiduciary duty, except for indemnification and insurance for a breach of the fiduciary duty to the company to the extent that the office holder acted in good faith and had a reasonable basis to believe that the act would not prejudice the company;

 

 

●

a breach of duty of care committed intentionally or recklessly, excluding a breach arising out of the negligent conduct of the office holder;

 

 

●

an act or omission committed with intent to derive illegal personal benefit; or

 

 

●

a fine, monetary sanction or forfeit levied against the office holder.

 

Under the Companies Law, exculpation, indemnification and insurance of office holders must generally 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 such controlling shareholders have a personal interest, also by the shareholders. The compensation committee may approve the procurement of directors’ and officers’ liability insurance policy without the need for shareholder approval, if it determines that, pursuant to the relief regulations promulgated under the Companies Law, the provision of such insurance coverage to the office holders under our directors and officers liabilities insurance policy is on market terms, is not likely to have a material adverse effect on our profits, assets or obligations, and is consistent with our Compensation Policy which was approved by our shareholders in accordance with the Companies Law.

 

II-2

 

 

 

Our amended and restated 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 within the parameters set forth in our Compensation Policy.

 

We have issued letters of indemnity (the “Indemnity Letters”) to each of our current office holders pursuant to which we undertook to indemnify such office holders to the fullest extent permitted by applicable law, to the extent that these liabilities are not covered by insurance. This indemnification is limited to events determined as foreseeable by our Board based on our activities, as set forth in the Indemnity Letters. According to the Indemnity Letters, the total accumulative sum of indemnification that may be paid by us to all office holders will not exceed a sum equal to 25% of our shareholders’ equity according to our latest audited or reviewed consolidated financial statements, as of the date of indemnification. The payment of indemnity amounts will not prejudice the right of office holders to receive insurance coverage benefits.

 

In addition, we have issued letters of exemption to each of our current office holders exculpating them from a breach of their duty of care to us to the fullest extent permitted by law.

 

We expect to indemnify Isaac Israel for obligations, including the deductibles for our directors’ and officers’ liability insurance policy, and we may be required to pay costs and expenses he may incur related to the “Atzmon Claim” described in “Item 8. Financial Information - A. Consolidated Statements and Other Financial Information - Legal Proceedings” of our Annual Report on Form 20-F for the year ended December 31, 2025, pursuant to the Indemnity Letter issued to him. To our knowledge, other than with respect to the foregoing proceeding, there is no previous or pending litigation or proceedings against any of our office holders as to which indemnification is being, or may be sought, nor are we aware of any other pending or threatened litigation or proceeding that may result in claims for indemnification by any office holder. 

 

Insofar as indemnifications for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling us pursuant to the foregoing provisions, we have been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

 

Item 9. Exhibits

 

The index to exhibits appears below on the page immediately preceding the signature pages of this Registration Statement.

 

Item 10. Undertakings

 

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;

 

II-3

 

 

 

 

(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 a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

 

 

(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 (1)(i), (1)(ii) and (1)(iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in this registration statement or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of this registration statement;

 

(2) That, for the purpose of determining any liability under the Securities Act, 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 (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 Item 8.A of Form 20-F 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.

 

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

 

 

(i)

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

 

II-4

 

 

 

 

(ii)

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 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 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 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 an 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.

 

(7) 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 Section 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.

 

(8) Insofar as indemnification for liabilities arising under the Securities Act 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 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 Securities Act and will be governed by the final adjudication of such issue.
