PROSPECTUS SUPPLEMENT

(To prospectus dated August 9, 2021)

1,084,923 American Depositary Shares representing 433,969,200 Ordinary Shares

Pre-funded Warrants to Purchase up to 217,000 American Depositary Shares

Up to 217,000 American Depositary Shares representing 86,800,000 Ordinary Shares

underlying the Pre-funded Warrants

RedHill Biopharma Ltd.

We are offering 1,084,923 American Depositary Shares (“ADSs”) in this offering. Each ADS represents 400 ordinary shares, par value NIS 0.01 per share (the “Ordinary Shares”). We are also offering Pre-funded Warrants to purchase 217,000 ADSs (the “Pre-funded Warrants”) to an institutional investor pursuant to this prospectus supplement, the accompanying prospectus and a securities purchase agreement dated as of July 21, 2023, by and among us and the purchasers signatory thereto (the “Securities Purchase Agreement”). The purchase price of each ADS is $1.35, and the purchase price of each Pre-funded Warrant is $1.349 (equal to the purchase price per ADS minus $0.001).

A holder of Pre-funded Warrants will not have the right to exercise any portion of its Pre-funded Warrants if the holder, together with its affiliates and certain related parties, would beneficially own in excess of 4.99% (or, at the election of the holder, 9.99%) of the number of the Ordinary Shares outstanding immediately after giving effect to such exercise. The Pre-funded Warrants may only be exercised to purchase whole ADSs at an exercise price of $0.001 per ADS. The Pre-funded Warrants are immediately exercisable and may be exercised at any time until all of the Pre-funded Warrants are exercised in full. There is no established public trading market for the Pre-funded Warrants, and we do not expect a market to develop. We do not intend to apply for listing of the Pre-funded Warrants on the Nasdaq Stock Market (“Nasdaq”) or any other securities exchange or nationally recognized trading system. Without an active trading market, the liquidity of the Pre-funded Warrants will be limited. The ADSs issuable from time to time upon exercise of the Pre-funded Warrants are also being offered by this prospectus supplement and the accompanying prospectus. We refer to the ADSs and the Pre-funded Warrants being offered hereby and the ADSs issued or issuable upon exercise of the Pre-funded Warrants being offered hereby, collectively, as the “securities.”

In connection with this offering, we agreed with the investors in this offering to amend (i) certain existing warrants to purchase up to an aggregate of 330,106 ADSs at an exercise price of $4.75 per ADS, issued on May 11, 2022, as subsequently amended effective as of April 3, 2023 (the “May 2022 Warrants”), and (ii) certain existing warrants to purchase up to an aggregate of 971,817 ADSs at an exercise price of $4.6305 per ADS issued on December 6, 2022 (the “December 2022 Warrants”), so that the amended warrants, in each case, will have a reduced exercise price of $1.80 per ADS, effective upon closing of this offering.

As of the date of this prospectus supplement, the aggregate market value of our outstanding Ordinary Shares held by non-affiliates pursuant to General Instruction I.B.5 of Form F-3 is $9,030,426.00, based on 1,556,970,344 Ordinary Shares outstanding held by non-affiliates (which would be represented by 3,892,425 ADSs), and a per ADS price of $2.32 per ADS, the closing price of the ADSs on May 31, 2023 as reported on Nasdaq. We have not sold any securities pursuant to General Instruction I.B.5 of Form F-3 during the 12 calendar months prior to and including the date of this prospectus supplement. Pursuant to General Instruction I.B.5 of Form F-3, in no event will we sell securities pursuant to the registration statement of which this prospectus supplement forms a part in a public primary offering with a value exceeding one-third of our outstanding voting and non-voting common equity held by non-affiliates (the “public float”) in any 12-month period so long as our public float remains below $75.0 million.

The ADSs are listed on Nasdaq under the symbol “RDHL.” On July 20, 2023, the last reported sale price of the ADSs on Nasdaq was $1.85 per ADS.

Investing in our securities involves a high degree of risk. Please read “Risk Factors” beginning on page S-11 of this prospectus supplement, on page 10 of the accompanying prospectus and in the documents incorporated by reference into this prospectus supplement.

None of the United States Securities and Exchange Commission, any state securities commission or any other regulatory body, has approved or disapproved of these securities or passed upon the adequacy or accuracy of this prospectus supplement or the accompanying prospectus. Any representation to the contrary is a criminal offense.

We have retained H.C. Wainwright & Co., LLC (“Wainwright” or the “Placement Agent”) to act as our placement agent in connection with this offering. The Placement Agent is not purchasing or selling any of the securities offered pursuant to this prospectus supplement and the accompanying prospectus and the Placement Agent is not required to arrange the purchase or sale of any specific number of securities or dollar amount, but it has agreed to use its best efforts to arrange for the sale of all of the securities.

We anticipate that delivery of the ADSs and the Pre-funded Warrants will be made on or about July 25, 2023, subject to satisfaction of customary closing conditions.

H.C. Wainwright & Co.

ABOUT THIS PROSPECTUS SUPPLEMENT

This prospectus supplement and the accompanying prospectus form part of the registration statement (No. 333-258259) that we filed with the Securities and Exchange Commission (“SEC”), using a “shelf” registration process. This document comprises two parts. The first part is this prospectus supplement, which describes the specific terms of this offering and also adds to and updates information contained in the accompanying base prospectus and the documents incorporated by reference herein. The second part, the accompanying base prospectus, gives more general information, some of which may not apply to this offering. Generally, when we refer to this prospectus, we are referring to both parts of this document combined. If the description of the offering varies between this prospectus supplement and the accompanying prospectus or the documents incorporated herein or therein by reference filed prior to the date of this prospectus supplement, you should rely on the information contained in this prospectus supplement. However, if any statement in one of these documents is inconsistent with a statement in another document having a later date - for example, a document incorporated by reference in the accompanying prospectus - the statement in the document having the later date modifies or supersedes the earlier statement.

We have not, and the Placement Agent has not, authorized anyone to provide information different from that contained in this prospectus supplement, the accompanying prospectus and any free writing prospectus that we have authorized for use in this offering. If anyone provides you with different or inconsistent information, you should not rely on it. Neither we nor the Placement Agent take any responsibility for, and can provide no assurance as to the reliability of, any other information that others may give you. You should not assume that the information contained in this prospectus supplement or the accompanying prospectus, or any document incorporated by reference in this prospectus supplement or the accompanying prospectus, is accurate as of any date other than the date on the front cover of the applicable document. Neither the delivery of this prospectus supplement, the accompanying prospectus and any free writing prospectus that we have authorized for use in this offering, nor the sale of our securities means that information contained in this prospectus supplement, the accompanying prospectus and any free writing prospectus that we have authorized for use in this offering, is correct after their respective dates. Our business, financial condition, results of operations and prospects may have changed since that date. It is important for you to read and consider all information contained in this prospectus supplement and the accompanying prospectus, including the information incorporated by reference into this prospectus supplement, the accompanying prospectus and any free writing prospectus that we have authorized for use in connection with this offering in making your investment decision.

Before purchasing any securities, you should carefully read both this prospectus supplement and the accompanying prospectus, together with the additional information described under the headings, “Where You Can Find More Information” and “Incorporation of Information by Reference,” on page S-31 of this prospectus supplement.

Unless the context otherwise requires, all references to “RedHill,” “we,” “us,” “our,” the “Company” and similar designations refer to RedHill Biopharma Ltd. and its wholly-owned subsidiary, RedHill Biopharma Inc.

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, including the “Item 3. Key Information - Risk Factors” in our Annual Report on Form 20-F for the year-ended December 31, 2022, in full.

• Our financial statements include a going concern reference.  We will need to raise significant additional capital to finance our losses and negative cash flows from operations, and if we were to fail to raise sufficient capital or on favorable terms and/or fail to replace Movantik® with another commercial product on a timely basis, we may need to cease operations. Management has substantial doubt about our ability to continue as a going concern.

• Following our sale of our rights to Movantik®, our revenue, business’ size and scope, market share and opportunities in certain markets, or our ability to compete in certain markets and therapeutic categories is reduced.

• Our ability to replace Movantik® with another commercial product, either internal or external, may not occur, and we may never achieve levels of revenue we have achieved through Movantik®.

• Our failure to maintain compliance with Nasdaq’s continued listing requirements could result in the desilting of the ADSs.

• Certain obligations under the Credit Agreement, dated February 3, 2020, as amended and the Asset Purchase Agreement, dated February 2, 2023 entered into with HCR Collateral Management, LLC (“HCRM”) and certain of its affiliates in connection with the sale of Movantik® in exchange for extinguishment of all debt obligations under the Credit Agreement are secured by a lien on Talicia®-related assets. As a result of this security interest, until extinguishment of such security interest, if we were to become insolvent the Talicia® assets would only be available to satisfy claims of our general creditors or to holders of our equity securities to the extent the value of such assets exceeded the amount of our indebtedness and other obligations. In addition, if we lose Talicia® to a foreclosure, we will lose our remaining source of revenue following the sale of Movantik®, assuming we are not able to replace Movantik® with another commercial product. The existence of these security interests may also adversely affect our financial flexibility.

• Our pursuit of treatments for SARS-CoV-2 (the virus that causes COVID-19) infection in patients entails a high level of uncertainty. We cannot assure you that either opaganib (ABC294640; Yeliva®) (“opaganib”) or RHB-107 will prove to be a safe and effective treatment for COVID-19, or will be approved for marketing or Emergency Use Authorization or be granted with Expanded Access clearance by the FDA or other regulatory authorities. In addition, we cannot assure that we will be able to complete the development of opaganib or RHB-107.

• If we are successful in developing a COVID-19 therapeutic, we may need to devote significant resources to our manufacturing scale-up and large-scale deployment, including for use by the U.S. or other governments. If one of our COVID-19 therapeutic candidates is approved for marketing or for Emergency Use, we may also need to devote significant resources to further expand our U.S. and non-U.S. sales and marketing activities and increase or maintain personnel to accommodate sales in the U.S. and outside the U.S.

• If we or our future development or commercialization partners are unable to obtain or maintain the FDA or other foreign regulatory clearance and approval for our commercial products or therapeutic candidates, we or our commercialization partners will be unable to commercialize our current commercial products, products we may commercialize or promote in the future or our therapeutic candidates, upon approval, if any.

PROSPECTUS SUPPLEMENT SUMMARY

This summary highlights selected information about us, this offering and information contained in greater detail elsewhere in this prospectus supplement, the accompanying prospectus, any free writing prospectus that we have authorized for use, and in the documents incorporated by reference. This summary is not complete and does not contain all of the information that you should consider before investing in the securities. You should carefully read and consider this entire prospectus supplement, the accompanying prospectus and the documents, including financial statements and related notes, and information incorporated by reference into this prospectus supplement, including the financial statements and “Risk Factors” starting on page S-11 of this prospectus supplement, before making an investment decision. If you invest in our securities, you are assuming a high degree of risk.

Our Business

We are a specialty biopharmaceutical company, primarily focused on gastrointestinal (“GI”) and infectious diseases. Our primary goal is to become a leading specialty biopharmaceutical company.

We are currently focused primarily on the commercialization in the U.S. of the GI-related products, Talicia® (omeprazole, amoxicillin, and rifabutin) and Aemcolo® (rifamycin).

In addition, we continue to develop our pipeline of clinical-stage therapeutic candidates, including, among others, opaganib and RHB-107 (upamostat), as potential treatments for COVID-19, and nuclear radiation protection development program opaganib, with newly published data from eight U.S. government-funded in vivo studies. We look for opportunities to leverage our commercial presence and capabilities in the U.S. to support the potential future launch of our therapeutic candidates currently under development, if approved by the FDA, or any FDA-approved products that we may acquire the rights to in the future.

Our current pipeline consists of five therapeutic candidates, most of which are in late-stage clinical development. We generate our pipeline of therapeutic candidates by identifying, validating and in-licensing or acquiring products that are consistent with our product and corporate strategy and that have the potential to exhibit a favorable probability of therapeutic and commercial success. We have one product that we primarily developed internally which has been approved for marketing and, to date, none of our therapeutic candidates has generated meaningful revenues. We have out-licensed one of our commercial products, Talicia®, and one of our clinical-stage therapeutic candidates, opaganib, for specific territories outside the U.S. and we plan to commercialize our therapeutic candidates, upon approval, if any, through licensing and other commercialization arrangements outside the U.S. with pharmaceutical companies on a global and territorial basis or, in the case of commercialization in the U.S., independently with our dedicated commercial operations or in potential partnership with other commercial-stage companies. We also evaluate, on a case-by-case basis, co-development, co-promotion, licensing, acquisitions and similar arrangements.

Kukbo Proceedings

We continue our litigation against Kukbo Co. Ltd. (“Kukbo”) which was filed on September 2022 as a result of Kukbo’s default in delivering to RedHill a total of $6.5 million under the Subscription Agreement, dated October 25, 2021 (the “Subscription Agreement”) and the Exclusive License Agreement, dated March 14, 2022. Following a recent court decision on our motion to dismiss Kukbo’s counterclaims, which dismissed certain (but not all) counterclaims, we filed a motion to reargue in light of a misstatement in the court’s order. The court granted an oral argument on the motion to reargue scheduled for August 10, 2023. We further plan to continue to rigorously pursue the Kukbo litigation.

Nasdaq Deficiency

On May 9, 2023, we received a written notification from the Nasdaq Stock, indicating that we are not in compliance with the minimum Market Value of Publicly Held Shares (“MVPHS”) set forth in the Nasdaq Listing Rules for continued listing on Nasdaq. Nasdaq Listing Rule 5450(b)(3)(C) requires companies to maintain a minimum MVPHS of $15 million, and Listing Rule 5810(c)(3)(D) provides that a failure to meet the MVPHS requirement exists if the deficiency continues for a period of 30 consecutive business days. Pursuant to Nasdaq Listing Rule 5810(c)(3)(D), we have a compliance period of 180 calendar days (or until November 6, 2023) to regain compliance. If at any time during this compliance period our MVPHS closes at $15 million or more for a minimum of ten consecutive business days, Nasdaq will notify us that we have achieved compliance with the MVPHS requirement, and the MVPHS matter will be closed. In the event we do not regain compliance with Rule 5450(b)(3)(C) prior to the expiration of the compliance period, we will receive written notification that our securities are subject to delisting.

March 2023 Offering and Related Warrant Amendment

On March 30, 2023, we entered into a securities purchase agreement with an institutional investor for the purchase and sale of (i) 270,000 ADSs, (ii) pre-funded warrants to purchase up to an aggregate of 1,230,000 ADSs (the “March 2023 Pre-funded Warrants”), (iii) Series A Warrants to purchase up to an aggregate of 1,500,000 ADSs, and (iv) Series B Warrants to purchase up to an aggregate of 1,500,000 ADSs at a combined offering price of $4.00 per ADS and accompanying Series A Warrant and Series B Warrants (or $3.999 per March 2023 Pre-funded Warrant and accompanying Series A Warrant and Series B Warrant). The offering (the “March 2023 Offering”) closed on April 3, 2023. The March 2023 Pre-funded Warrants had an exercise price of $0.001 per ADS, were exercisable immediately and terminated when exercised in full. All of the March 2023 Pre-funded Warrants have been exercised. The Series A Warrants have an initial exercise price of $4.75 per ADS, prior to giving effect to the reduction in the exercise price of the Series A Warrant pursuant to the Exercise Agreement (as defined below), are exercisable immediately and have a term of five years following issuance. The Series B Warrants have an initial exercise price of $4.00 per ADS, prior to giving effect to the reduction in the exercise price of the Series B Warrant pursuant to the Exercise Agreement, are exercisable immediately and have a term of nine months following issuance. The gross proceeds to us from the March 2023 offering were approximately $6 million, before deducting the placement agent’s fees and other offering expenses payable by us.

In connection with the March 2023 Offering, we amended the May 2022 Warrants, which had an exercise price of $59.20 per ADS and a termination date of November 11, 2027, so that the amended warrants would have a reduced exercise price of $4.75 per ADS and a termination date of April 3, 2028, effective upon the closing of the March 2023 Offering (prior to giving effect to the Warrant Amendment (as defined below)).

Amendment of May 2022 Warrants and the December 2022 Warrants

In connection with this offering, we agreed with the investors in this offering to amend (i) the May 2022 Warrants to purchase up to an aggregate of 330,106 ADSs at an exercise price of $4.75 per ADS, issued on May 11, 2022, as subsequently amended effective as of April 3, 2023, and (ii) the December 2022 Warrants to purchase up to an aggregate of 971,817 ADSs at an exercise price of $4.6305 per ADS issued on December 6, 2022, so that the amended warrants, in each case, will have a reduced exercise price of $1.80 per ADS, effective upon closing of this offering (the “Warrant Amendment”).

March 2023 Warrant Exercise Transaction

On July 21, 2023, we entered into a warrant reprice and reload letter (the “Exercise Agreement”) with an investor in this offering, holding Series A Warrants to purchase up to an aggregate of 1,500,000 ADSs and Series B Warrants to purchase up to an aggregate of 1,500,000 ADSs previously issued in the March 2023 Offering, pursuant to which such investor agreed to exercise its Series A Warrants in full at a reduced exercised price of $1.35 per ADS (the “Series A Warrant Exercise”), for gross proceeds of $2,025,000.

In consideration for the exercise of the Series A Warrants for cash (i) the exercising holder will receive new unregistered warrants to purchase up to an aggregate of 1,500,000 ADSs at an exercise price of $1.80 per ADS which shall be exercisable until April 3, 2028 (the “Reload Warrant”), and (ii) the exercise price of the Series B Warrants to purchase up to an aggregate of 1,500,000 ADSs will be reduced to $1.80 per ADS.

The Reload Warrant described above is being offered in a private placement under Section 4(a)(2) of the Securities Act and Regulation D promulgated thereunder and, along with the ADSs representing Ordinary Shares underlying the Reload Warrant, have not been registered under the Securities Act or applicable state securities laws.

As part of the transaction, we agreed to file a resale registration statement on Form F-3 (or other appropriate form if we are not then F-3 eligible) with the SEC within 15 days of the date of the Exercise Agreement to register the resale of the ADSs underlying the Reload Warrant.

In connection with the Series A Warrant Exercise and issuance of the Reload Warrant, we agreed to pay the Placement Agent a cash fee equal to 7.5% of the aggregate gross proceeds of the exercise of the Series A Warrant. In addition, we agreed to issue to the Placement Agent or its designees, warrants to purchase up to an aggregate of 90,000 ADSs at an exercise price of $1.6875 per ADS which shall be exercisable until April 3, 2028.

THE OFFERING
ADSs offered by us	1,084,923 ADSs representing 433,969,200 Ordinary Shares.
Pre-funded Warrants offered by us	We are offering Pre-funded Warrants to purchase up to 217,000 ADSs to a purchaser, whose purchase of ADSs in this offering would otherwise result in the purchaser, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding Ordinary Shares immediately following the consummation of this offering. Each Pre-funded Warrant is exercisable for one ADS. The purchase price of each Pre-funded Warrant is equal to the price at which each ADS is being sold in this offering, minus $0.001, and the exercise price of each Pre-funded Warrant is $0.001 per ADS. The Pre-funded Warrants are exercisable immediately and may be exercised at any time until all of the Pre-funded Warrants are exercised in full. This prospectus supplement also relates to the offering of 217,000 ADSs issuable upon exercise of the Pre-funded Warrants. See “Description of Securities.”
Ordinary Shares to be outstanding after this offering(1)	2,099,714,094 Ordinary Shares, assuming exercise in full of the Pre-funded Warrants offered in this offering.
The ADSs	Each ADS represents 400 Ordinary Shares. The ADSs will be delivered by The Bank of New York Mellon, as depositary (the “Depositary”). The Depositary, as depositary, or its nominee, will be the holder of the Ordinary Shares underlying your ADSs and you will have rights as provided in the Deposit Agreement, dated as of December 26, 2012, among us, the Depositary and all owners and holders from time to time of ADSs issued thereunder (the “Deposit Agreement”), a form of which has been filed as Exhibit 1 to the Registration Statement on Form F-6 filed by the Depositary with the SEC on December 6, 2012. Subject to the terms of the Deposit Agreement and in compliance with the relevant requirements set out in the prospectus, you may turn in your ADSs to the Depositary for cancellation and withdrawal of the Ordinary Shares underlying your ADSs. The Depositary will charge you fees for such cancellations pursuant to the Deposit Agreement. You should carefully read the “Description of American Depositary Shares” section of the accompanying prospectus and the Deposit Agreement to better understand the terms of the ADSs.
Use of proceeds	We expect to receive net proceeds of approximately $1.4 million from this offering, after deducting the placement agent fees and estimated offering expenses payable by us (excluding proceeds from the Series A Warrant Exercise and assuming no exercise of the Reload Warrant issued pursuant to the Exercise Agreement). We intend to use the net proceeds from the offering, together with our existing cash and cash equivalents, for working capital, acquisitions, research and development, and general corporate purposes. See “Use of Proceeds.”
Risk factors	Before deciding to invest in the securities, you should carefully consider the risks related to our business, the offering, the ADSs and the Ordinary Shares, and our location in Israel.

(1) The number of Ordinary Shares to be outstanding immediately after the offering, as shown above, is based on 1,578,944,894 Ordinary Shares outstanding as of July 20, 2023. As of July 20, 2023, we had (i) 43,824,000 Ordinary Shares issuable upon the exercise of outstanding options to purchase Ordinary Shares at a weighted average exercise price of $0.49 per share (equivalent to 109,560 ADSs at a weighted average exercise price of $195.59 per ADS), (ii) 2,059,112,400 Ordinary Shares issuable upon the exercise of outstanding warrants to purchase Ordinary Shares at a weighted average exercise price of $0.01 per share (equivalent to 5,147,781 ADSs at a weighted average exercise price of $4.50 per ADS), and (iii) 235,353 outstanding Restricted Share Units (“RSUs”), each RSU representing one ADS. The number of Ordinary Shares to be outstanding immediately after the offering does not include the ADSs we agreed to issue to Kukbo for the second tranche of $5 million pursuant to the Subscription Agreement.

Unless otherwise stated, outstanding share information throughout this prospectus supplement excludes such outstanding securities and assumes no exercise of the outstanding options or warrants described above.

Except as otherwise indicated, the information in this prospectus supplement, including the number of Ordinary Shares that will be outstanding after this offering (i) assumes full exercise of the Pre-funded Warrants offered in this offering for cash, (ii) no exercise of the Placement Agent Warrants to be issued to the Placement Agent or its designees in connection with this offering, and (iii) does not give effect to the Warrant Amendment and the transactions contemplated pursuant to the Exercise Agreement.

RISK FACTORS

You should carefully consider the risks described below and in our annual report on Form 20-F for the year ended December 31, 2022, as well as the other information included or incorporated by reference in this prospectus supplement and the accompanying prospectus, including our financial statements and the related notes, before you decide to buy our securities. The risks and uncertainties described below and incorporated by reference in this prospectus supplement are not the only risks facing us. We may face additional risks and uncertainties not currently known to us or that we currently deem to be immaterial. Any of the risks described below or incorporated by reference in this prospectus supplement, and any such additional risks, could materially adversely affect our business, financial condition or results of operations. In such case, you may lose all or part of your original investment.

Risks Related to The ADSs

Our failure to maintain compliance with Nasdaq’s continued listing requirements could result in the desilting of the ADSs.

The ADSs are currently listed for trading on Nasdaq. We must satisfy Nasdaq’s continued listing requirements, including, among other things, a minimum MVPHS and a minimum closing bid price of $1.00 per ADS or risk delisting, which would have a material adverse effect on our business.

On May 9, 2023, we received a written notification from the Nasdaq Stock, indicating that we are not in compliance with the minimum MVPHS set forth in the Nasdaq Listing Rules for continued listing on Nasdaq. Nasdaq Listing Rule 5450(b)(3)(C) requires companies to maintain a minimum MVPHS of $15 million, and Listing Rule 5810(c)(3)(D) provides that a failure to meet the MVPHS requirement exists if the deficiency continues for a period of 30 consecutive business days. Pursuant to Nasdaq Listing Rule 5810(c)(3)(D), we have a compliance period of 180 calendar days (or until November 6, 2023) to regain compliance.

We will seek to regain compliance with all applicable Nasdaq requirements within the allotted compliance period. If we do not regain compliance within the allotted compliance period, including any extensions that may be granted by Nasdaq, Nasdaq will provide notice that the ADSs will be subject to delisting.

Further, even if we regain compliance with the minimum MVPHS requirement, no assurance can be given that we will be able to comply with the other standards that we are required to meet in order to maintain a listing on such exchange, such as the minimum stockholders’ equity or the minimum closing bid price requirements. In the recent past, we did not meet the minimum closing bid price requirement and only regained compliance with that requirement in April 2023, after completing a ratio change of the ADSs to our non-traded Ordinary Shares from the previous ratio of one ADS representing ten Ordinary Shares to a new ratio of one ADS representing 400 Ordinary Shares. No assurance can be given that the price of the ADSs will not again be in violation of Nasdaq’s minimum bid price rule in the future. Our failure to meet these requirements may result in our securities being delisted from Nasdaq.

A delisting could substantially decrease trading in the ADSs, adversely affect the market liquidity of the ADSs as a result of the loss of market efficiencies associated with Nasdaq and the loss of federal preemption of state securities laws, adversely affect our ability to obtain financing on acceptable terms, if at all, and may result in the potential loss of confidence by investors, suppliers, customers and employees and fewer business development opportunities. Additionally, the market price of the ADSs may decline further and stockholders may lose some or all of their investment.

U.S. holders of ADSs may suffer adverse tax consequences if we were characterized as a passive foreign investment company.

Based on the current composition of our gross income and assets and on reasonable assumptions and projections, we believe we should not be treated as a passive foreign investment company (a “PFIC”), for U.S. federal income tax purposes for 2023. However, there can be no assurance that this will be the case in 2023 or in future taxable years. If we were characterized as a PFIC, U.S. holders of the ADSs and Pre-funded Warrants may suffer adverse tax consequences such as (i) having gains realized on the sale of the ADSs or Pre-funded Warrants treated as ordinary income rather than capital gain, not qualifying for the preferential rate otherwise applicable to dividends received in respect of the ADSs or Pre-funded Warrants by individuals who are U.S. holders, and (ii) having interest charges apply to certain distributions by us and upon certain sales of the ADSs or Pre-funded Warrants.

Risks Related to the Offering

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

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

You may experience immediate and substantial dilution in book value of any ADSs or ADSs that may be issued upon the exercise of any Pre-funded Warrants you purchase.

The offering price of the ADSs or the ADSs that may be issued upon the exercise of Pre-funded Warrants offered hereby is substantially higher than the net tangible book value per ADS. Therefore, if you purchase securities in this offering, you will pay a price per ADS or ADS that may be issued upon the exercise of any Pre-funded Warrants that substantially exceeds our net tangible book value per ADS or ADS that may be issued upon the exercise of any Pre-funded Warrants after this offering. To the extent outstanding options or warrants are exercised, you will incur further dilution. Based on the offering price of $1.35 per ADS, you will experience immediate dilution of $2.06 per ADS or ADSs that may be issued upon the exercise of Pre-funded Warrants, representing the difference between the offering price per ADS and our pro forma as adjusted net tangible book value per ADS as of March 31, 2023 after giving effect to the Pro Forma Adjustments (as defined in “Capitalization and Indebtedness” on page S-14), this offering, after deducting the placement agent fees and commissions and estimated offering expenses payable by us, and the Warrant Amendment and the transactions contemplated pursuant to the Exercise Agreement. See “Dilution” on page S-15 for a more detailed discussion of the dilution you will incur in connection with this offering.

Future sales of the ADSs, including any ADSs issuable upon the exercise of the Pre-funded Warrants, or the perception that future sales may occur, may cause the market price of the ADSs to decline, even if our business is doing well.

Sales by the ADS holders of a substantial number of ADSs in the public market could occur in the future. These sales, or the perception in the market that the holders of a large number of ADSs intend to sell shares, may cause the market price of the ADSs to decline. In addition, we will be issuing the Pre-funded Warrants in this offering. To the extent that holders of the Pre-funded Warrants or other existing warrants sell the ADSs issued upon the exercise of such warrants, the market price of the ADSs may decrease due to the additional selling pressure in the market. Moreover, the risk of dilution from issuances of ADSs underlying the Pre-funded Warrants may cause shareholders to sell their ADSs, which could cause a further decline in the market price.

You may experience future dilution as a result of future equity offerings.

To raise additional capital, we may in the future offer additional ADSs, Ordinary Shares or other securities convertible into or exchangeable for the ADSs or Ordinary Shares at prices that may not be the same as the price per ADS in this offering. We may sell ADSs, Ordinary Shares or other securities in any other offering at a price per ADS or per Ordinary Share, as appliable, that is less than the price per ADS paid by investors in this offering, and investors purchasing ADSs, Ordinary Shares or other securities in the future could have rights superior to the rights of ADSs holders. The price per ADS or per share at which we sell additional ADSs, Ordinary Shares, as applicable, or securities convertible or exchangeable into ADSs or Ordinary Shares, in future transactions, may be higher or lower than the price per ADS paid by investors in this offering. In addition, we agreed to amend the May 2022 Warrants and December 2022 Warrants held by the investors in this offering, so that the amended warrants will have a reduced exercise price of $1.80 per ADS, effective upon closing of this offering, and reduce the exercise price of the Series B Warrants pursuant to the Exercise Agreement to $1.80 per ADS.

Holders of the Pre-funded Warrants purchased in this offering will have no rights as ADS holders until such holders exercise such Pre-funded Warrants and acquire the ADSs.

Until holders of the Pre-funded Warrants purchased in this offering acquire the ADSs upon exercise thereof, holders of the Pre-funded Warrants will have no rights with respect to the ADSs underlying the Pre-funded Warrants. Upon exercise of any of the Pre-funded Warrants purchased in this offering, such holders will be entitled to exercise the rights of an ADS holder only as to matters for which the record date occurs after the exercise date.

S - 12

USE OF PROCEEDS

We estimate that the net proceeds from the sale of ADSs representing Ordinary Shares in this offering will be approximately $1.4 million, assuming exercise of all Pre-funded Warrants being issued in this offering for cash and after deducting the placement agent fees and estimated offering expenses payable by us in connection with this offering, excluding proceeds from the Series A Warrant Exercise and assuming no exercise of the Reload Warrant issued pursuant to the Exercise Agreement.

We intend to use the net proceeds from this offering, together with our existing cash and cash equivalents, for working capital, acquisitions, research and development, and general corporate purposes.

The amounts and timing of our actual expenditures will depend upon numerous factors, including the progress of our development and commercialization efforts, the status of and results from our clinical trials, whether or not we enter into strategic collaborations or partnerships, and our operating costs and expenditures. Accordingly, our management will have significant flexibility in applying the net proceeds of this offering. In addition, while we have not entered into any binding agreements or commitments relating to any significant transaction as of the date of this prospectus supplement that we expect to use the net proceeds from this offering, we may use a portion of the net proceeds to pursue acquisitions, joint ventures and other strategic transactions.

CAPITALIZATION AND INDEBTEDNESS

The following table sets forth our total capitalization as of March 31, 2023:

• on an actual basis;

• on a pro forma basis, after giving effect to (i) the March 2023 Offering (including the issuance of Series A Warrants and Series B Warrants), giving effect to the exercise in full of the March 2023 Pre-funded Warrants to purchase an aggregate of 1,230,000 ADSs for aggregate cash consideration of $1,230.00, after March 31, 2023, and after deducting placement agent fees and offering expenses paid by us in connection with the March 2023 Offering, and the amendment to the May 2022 Warrants, effective upon closing of the March 2023 Offering (the “Pro Forma Adjustments”); and

• on a pro forma as adjusted basis to give further effect to (i) the sale of the ADSs and Pre-funded Warrants in this offering, assuming full exercise of the Pre-funded Warrants offered in this offering for cash, and after deducting placement agent fees and estimated offering expenses payable by us, (ii) the Warrant Amendment reducing the exercise price of the May 2022 Warrants and December 2022 Warrants to $1.80 per ADS, to become effective upon the closing of this offering, and (iii) the exercise of the Series A Warrants to purchase 1,500,000 ADSs at a reduced exercise price of $1.35 per ADS, assuming that the underlying ADSs have been issued, the issuance of the Reload Warrant, and the reduction in the exercise price of the Series B Warrants, in each case, pursuant to the Exercise Agreement, and after deducting placement agent fees.

The information set forth in the following table should be read in conjunction with and is qualified in its entirety by reference to the audited and unaudited financial statements and notes thereto incorporated by reference in this prospectus supplement and the accompanying prospectus.

(In thousands, except share data)	Actual		Pro Forma		Pro Forma As Adjusted
Total debt(1)	$	56,830	$	58,995	$	62,558

(1)  Includes $48.4 million reported as current liabilities, which mainly consist of allowance for deductions from revenue and accrued expenses and account payable, and $8.4 million reported as non-current liabilities, which mainly consist of lease liabilities and derivative financial instruments. The warrants were classified as a financial liability due to a net settlement provision. Therefore, the proceeds of the issuances were classified as derivative financial instruments and increased the total debt accordingly.

The above discussion and table are based on 1,082,007,694 Ordinary Shares outstanding as of March 31, 2023. As of March 31, 2023, prior to giving effect to the Warrant Amendment and the transactions contemplated pursuant to the Exercise Agreement, we had (i) 50,511,200 Ordinary Shares issuable upon the exercise of outstanding options to purchase Ordinary Shares at a weighted average exercise price of $0.63 per share (equivalent to 126,278 ADSs at a weighted average exercise price of $252.54 per ADS), (ii) 823,112,400  Ordinary Shares issuable upon the exercise of outstanding warrants to purchase Ordinary Shares at a weighted average exercise price of $0.03 per share (equivalent to 2,057,781 ADSs at a weighted average exercise price of $13.38 per ADS), and (iii) 62,451 outstanding RSUs, each RSU representing one ADS. The number of Ordinary Shares to be outstanding immediately after the offering does not include the ADSs we agreed to issue to Kukbo for the second tranche of $5 million pursuant to the Subscription Agreement.

DILUTION

If you invest in the ADSs or Pre-funded Warrants, your interest will be diluted immediately to the extent of the difference between the effective offering price per ADS you will pay in this offering and our pro forma as adjusted net tangible book value per ADS after giving effect to this offering.

Our net tangible book value as of March 31, 2023 was approximately $(2.7) million, or approximately $(1.12) per ADS. Net tangible book value represents the amount of our total tangible assets minus total liabilities, net of leases presented as right-of-use assets and lease liabilities.

Our pro forma net tangible book value as of March 31, 2023, after giving effect to the Pro Forma Adjustments, would have been approximately $(4.5) million, or approximately $(1.14) per ADS.

After giving further effect to (i) this offering (which includes the issuance and sale of 1,084,923 ADSs and Pre-funded Warrants to purchase up to an aggregate of 217,000 ADSs), assuming full exercise of the Pre-funded Warrants to be issued in this offering for cash and after deducting placement agent fees and estimated offering expenses payable by us, (ii) the Warrant Amendment reducing the exercise price of the May 2022 Warrants and the December 2022 Warrants to $1.80 per ADS, to become effective upon the closing of this offering, and (iii) the exercise of the Series A Warrants to purchase 1,500,000 ADSs at a reduced exercise price of $1.35 per ADS, assuming that the underlying ADSs have been issued, the issuance of the Reload Warrant, and the reduction in the exercise price of the Series B Warrants, in each case, pursuant to the Exercise Agreement, and after deducting placement agent fees, our pro forma as adjusted net tangible book value as of March 31, 2023, would have been approximately $(4.8) million, or $(0.71) per ADS. This represents an immediate increase net tangible book value of $0.43 per ADS to our existing shareholders and an immediate dilution of approximately $2.06 per ADS to purchasers of securities in this offering, as illustrated by the following table:

Offering price per ADS				$	1.35
Net tangible book value per ADS as of March 31, 2023	$	(1.12	)
Increase in net tangible book value per ADS attributable to the Pro Forma Adjustments	$	(0.02	)
Pro forma net tangible book value per ADS as of March 31, 2023	$	(1.14	)
Increase in pro forma net tangible book value per ADS attributable to this offering	$	0.43
Pro forma as adjusted net tangible book value per ADS as of March 31, 2023 after giving effect to this offering	$	(0.71	)
Dilution in pro forma as adjusted net tangible book value per ADS to investors purchasing ADSs in this offering				$	2.06

The above discussion and table are based on 1,082,007,694 Ordinary Shares outstanding as of March 31, 2023. As of March 31, 2023, prior to giving effect to the Warrant Amendment and the transactions contemplated pursuant to the Exercise Agreement, we had (i) 50,511,200 Ordinary Shares issuable upon the exercise of outstanding options to purchase Ordinary Shares at a weighted average exercise price of $0.63 per share (equivalent to 126,278 ADSs at a weighted average exercise price of $252.54 per ADS), (ii) 823,112,400 Ordinary Shares issuable upon the exercise of outstanding warrants to purchase Ordinary Shares at a weighted average exercise price of $0.03 per share (equivalent to 2,057,781 ADSs at a weighted average exercise price of $13.38 per ADS), and (iii) 62,451 outstanding RSUs, each RSU representing one ADS. The number of Ordinary Shares to be outstanding immediately after the offering does not include the ADSs we agreed to issue to Kukbo for the second tranche of $5 million pursuant to the Subscription Agreement.

Except as otherwise indicated herein, outstanding share information throughout this prospectus supplement excludes such outstanding securities and assumes (i) no exercise of the outstanding options or warrants described above and (ii) no vesting of the RSUs described above.

The pro forma and pro forma as adjusted information discussed above is illustrative only. To the extent that outstanding exercisable options or warrants are exercised, you may experience further dilution. In addition, we may choose to raise additional capital due to market conditions or strategic considerations. To the extent that we raise additional capital by issuing equity or convertible debt securities, your ownership will be further diluted.

DIVIDEND POLICY

We have never declared or paid any cash dividends to our shareholders. We currently anticipate that we will retain future earnings for the development, operation and expansion of our business and do not anticipate declaring or paying any cash dividends for the foreseeable future.

DESCRIPTION OF SECURITIES WE ARE OFFERING

We are offering 1,084,923 ADSs and Pre-funded Warrants to purchase up to 217,000 ADSs. The following description of the ADSs and Pre-funded Warrants summarizes the material terms and provisions thereof, including the material terms of the ADSs and Pre-funded Warrants we are offering under this prospectus supplement and the accompanying prospectus. This prospectus supplement also relates to the offering of ADSs issuable upon exercise, if any, of the Pre-funded Warrants issued in this offering.

Authorized Share Capital. Our authorized share capital is 10,000,000,000 shares, consisting of (i) 9,994,000,000 registered Ordinary Shares of NIS 0.01 par value each, and (ii) 6,000,000 preferred shares of NIS 0.01 par value each, and as of July 20, 2023, we had 1,578,944,894 Ordinary Shares outstanding (which would be represented by 3,947,362 ADSs) and no preferred shares outstanding.

American Depositary Shares

The material terms and provisions of the ADSs and other outstanding securities convertible into or exercisable for ADSs are described in the accompanying prospectus and Exhibit 2.3, Description of Share Capital, to our annual report on Form 20-F for the year ended December 31, 2021, which are incorporated by reference into this prospectus supplement.

Pre-funded Warrants

The term “pre-funded” refers to the fact that the purchase price of ADSs in this offering includes almost the entire exercise price that will be paid under the Pre-funded Warrants, except for a nominal remaining exercise price of $0.001. The following summary of certain terms and provisions of the Pre-funded Warrants that are being offered hereby is not complete and is subject to, and qualified in its entirety by, the provisions of the Pre-funded Warrants, the form of which is or shall be filed as an exhibit to a Report on Form 6-K which shall be incorporated by reference into the registration statement of which this prospectus forms a part. Prospective investors should carefully review the terms and provisions of the form of Pre-funded Warrants for a complete description of the terms and conditions of the Pre-funded Warrants.

The purpose of the Pre-funded Warrants is to enable investors that may have restrictions on their ability to beneficially own more than 4.99% (or, upon election of the holder, 9.99%) of our outstanding Ordinary Shares following the consummation of this offering the opportunity to make an investment in the Company without triggering their ownership restrictions, by receiving Pre-funded Warrants in lieu of ADSs which would result in such ownership of more than 4.99% (or 9.99%), and receive the ability to exercise their option to purchase the shares underlying the Pre-funded Warrants at such nominal price at a later date.

Duration and Exercise Price

Each Pre-funded Warrant offered hereby has an initial exercise price per ADS equal to $0.001. Pre-funded Warrants are immediately exercisable and may be exercised at any time until the Pre-funded Warrants are exercised in full. The exercise price and number of ADSs issuable upon exercise is subject to appropriate adjustment in the event of share dividends, share splits, reorganizations or similar events affecting the Ordinary Shares and the exercise price.

Exercisability

The Pre-funded Warrants are exercisable, at the option of each holder, in whole or in part, by delivering to us a duly executed exercise notice accompanied by payment in full for the number of ADSs purchased upon such exercise (except in the case of a cashless exercise as discussed below). Purchasers of the Pre-funded Warrants in this offering may elect to deliver their exercise notice following the pricing of the offering and prior to the issuance of the Pre-funded Warrants at closing to have their Pre-funded Warrants exercised immediately upon issuance and receive ADSs underlying the Pre-funded Warrants upon closing of this offering. A holder (together with its affiliates) may not exercise any portion of the Pre-funded Warrants to the extent that the holder would own more than 4.99% of the outstanding Ordinary Shares (or, at the election of the purchaser, 9.99%), except that upon at least 61 days’ prior notice from the holder to us, a holder with a 4.99% ownership blocker may increase the amount of ownership of outstanding shares after exercising the holder’s Pre-funded Warrants up to 9.99% of our outstanding Ordinary Shares. No fractional ADSs will be issued in connection with the exercise of a Pre-funded Warrant. In lieu of fractional shares, we may, at our election, either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the exercise price of the Pre-funded Warrant or round up to the next whole ADS.

S - 17

Cashless Exercise

In lieu of making the cash payment otherwise contemplated to be made to us upon such exercise in payment of the aggregate exercise price, the holder may elect instead to receive upon such exercise (either in whole or in part) the net number of ADSs determined according to a formula set forth in the Pre-funded Warrants.

Transferability

Subject to applicable laws, a Pre-funded Warrant may be transferred at the option of the holder upon surrender of the Pre-funded Warrant to us together with the appropriate instruments of transfer.

Exchange Listing

There is no trading market available for the Pre-funded Warrants on any securities exchange or nationally recognized trading system. We do not intend to list the Pre-funded Warrants on any securities exchange or nationally recognized trading system, nor do we have any obligation to do so.

Right as a Shareholder

Except as otherwise provided in the Pre-funded Warrants or by virtue of such holder’s ownership of the ADSs or Ordinary Shares, the holders of the Pre-funded Warrants do not have the rights or privileges of holders of the ADSs or Ordinary Shares, including any voting rights, until they exercise their Pre-funded Warrants.

Fundamental Transaction

If, at any time while the Pre-funded Warrants are outstanding, (1) we, directly or indirectly, consolidate or merge with or into another person, (2) we, directly or indirectly, sell, lease, license, assign, transfer, convey or otherwise dispose of all or substantially all of our assets, (3) any direct or indirect purchase offer, tender offer or exchange offer (whether by us or another person) is completed pursuant to which holders of the Ordinary Shares (including any Ordinary Shares underlying ADSs) are permitted to sell, tender or exchange their Ordinary Shares for other securities, cash or property and has been accepted by the holders of 50% or more of our outstanding Ordinary Shares (including any Ordinary Shares underlying ADSs), (4) we, directly or indirectly, effect any reclassification, reorganization or recapitalization of the Ordinary Shares or any compulsory share exchange pursuant to which the Ordinary Shares are converted into or exchanged for other securities, cash or property, or (5) we, directly or indirectly, consummate a stock or share purchase agreement or other business combination with another person whereby such other person acquires more than 50% of our outstanding Ordinary Shares (including any Ordinary Shares underlying ADSs) or 50% or more of the voting power of the common equity of the Company, each, a “Fundamental Transaction”, then upon any subsequent exercise of the Pre-funded Warrants, a holder thereof will have the right to receive the same amount and kind of securities, cash or property as it would have been entitled to receive upon the occurrence of such Fundamental Transaction if it had been, immediately prior to such Fundamental Transaction, the holder of the number of ADSs then issuable upon exercise of the Pre-funded Warrant, and any additional consideration payable as part of the Fundamental Transaction.

MATERIAL TAX CONSIDERATIONS

Israeli Tax Considerations

General

The following is a summary of the material tax consequences under Israeli law concerning the purchase, ownership and disposition of American Depositary Shares, representing Ordinary Shares, Pre-funded Warrants and Warrants (collectively, the “Shares”) by persons who acquired the Shares in this offering.

This discussion does not purport to constitute a complete analysis of all potential tax consequences applicable to investors upon purchasing, owning or disposing of our Shares. In particular, this discussion does not take into account the specific circumstances of any particular investor (such as tax-exempt entities, financial institutions, certain financial companies, broker-dealers, investors that own, directly or indirectly, 10% or more of our outstanding voting rights, all of whom are subject to special tax regimes not covered under this discussion). To the extent that issues discussed herein are based on legislation that has yet to be subject to judicial or administrative interpretation, there can be no assurance that the views expressed herein will accord with any such interpretation in the future.

Potential investors are urged to consult their own tax advisors as to the Israeli or other tax consequences of the purchase, ownership, and disposition of the Shares, including, in particular, the effect of any foreign, state or local taxes.

General Corporate Tax Structure in Israel

Israeli companies are generally subject to corporate tax on their taxable income at the rate of 23% for the 2023 tax year.

Taxation of Shareholders

Capital Gains

Capital gains tax is imposed on the disposition of capital assets by an Israeli resident and on the disposition of such assets by a non-Israeli resident if those assets are either (i) located in Israel; (ii) are shares or a right to a share in an Israeli resident corporation, or (iii) represent, directly or indirectly, rights to assets located in Israel, unless an exemption is available or unless an applicable double tax treaty between Israel and the seller’s country of residence provides otherwise. The Israeli Income Tax Ordinance distinguishes between “Real Gain” and the “Inflationary Surplus”. “Real Gain” is the excess of the total capital gain over Inflationary Surplus generally computed on the basis of the increase in the Israeli Consumer Price Index between the date of purchase and the date of disposition. Inflationary Surplus is not subject to tax.

Real Gain accrued by individuals on the sale of the Shares will be taxed at the rate of 25%. However, if the individual shareholder is a “Controlling Shareholder” (i.e., a person who holds, directly or indirectly, alone or together with another, 10% or more of one of the Israeli resident company’s means of control) at the time of sale or at any time during the preceding 12-month period, such gain will be taxed at the rate of 30%.

Corporate and individual shareholders dealing in securities in Israel are taxed at the tax rates applicable to business income (23% in 2019 and thereafter), and a marginal tax rate of up to 50% in 2023 for individuals, including an excess tax (as discussed below).

Notwithstanding the foregoing, capital gains generated from the sale of our Shares by a non-Israeli shareholder may be exempt from Israeli tax under the Israeli Income Tax Ordinance provided (among other conditions) that seller does not have a permanent establishment in Israel to which the generated capital gain is attributed. However, non-Israeli resident corporations will not be entitled to the foregoing exemption if Israeli residents: (i) have a 25% or more interest in such non-Israeli corporation or (ii) are the beneficiaries of, or are entitled to, 25% or more of the income or profits of such non-Israeli corporation, whether directly or indirectly. In addition, such exemption would not be available to a person whose gains from selling or otherwise disposing of the securities are deemed to be business income.

S - 19

In addition, the sale of the Shares may be exempt from Israeli capital gains tax under the provisions of an applicable double tax treaty. For example, the Convention Between the Government of the United States of America and the Government of the State of Israel with Respect to Taxes on Income, or the U.S.-Israel Double Tax Treaty, exempts a U.S. resident (for purposes of the U.S.-Israel Double Tax Treaty) from Israeli capital gain tax in connection with the sale of the Shares, provided (among other conditions) that: (i) the U.S. resident owned, directly or indirectly, less than 10% of the voting power of the company at any time within the 12-month period preceding such sale; (ii) the U.S. resident, being an individual, is present in Israel for a period or periods of less than 183 days during the taxable year; and (iii) the capital gain from the sale was not derived through a permanent establishment of the U.S. resident in Israel; however, under the U.S.-Israel Double Tax Treaty, the taxpayer should be permitted to claim a credit for such taxes against the U.S. federal income tax imposed with respect to such sale, exchange or disposition, subject to the limitations under U.S. law applicable to foreign tax credits. The U.S.-Israel Double Tax Treaty does not relate to U.S. state or local taxes.

Payers of consideration for the Ordinary Shares, including the purchaser, the Israeli stockbroker or the financial institution through which the Shares are held, are obligated, subject to certain exemptions, to withhold tax upon the sale of Shares at a rate of 25% of the consideration for individuals and corporations.

Upon the sale of traded securities, a detailed return, including a computation of the tax due, must be filed and an advance payment must be paid to the Israeli Tax Authority on January 31 and July 31 of every tax year in respect of sales of traded securities made within the previous six months. However, if all tax due was withheld at source according to applicable provisions of the Israeli Income Tax Ordinance and regulations promulgated thereunder, such return need not be filed, and no advance payment must be paid. Capital gains are also reportable on annual income tax returns.

Exercise of Warrants and Certain Adjustments to the Warrants

Investors will generally not recognize gain or loss for Israeli tax purposes on the exercise of a Warrant and related receipt of an ordinary share (unless, for instance, cash is received in lieu of the issuance of a fractional ordinary share). Nevertheless, the Israeli income tax treatment and the tax consequences of a cashless exercise of Warrants into Ordinary Shares is unclear. Furthermore, the exercise terms of the Warrants may be adjusted in certain circumstances. An adjustment to the number of Ordinary Shares that will be issued on the exercise of the Warrants or an adjustment to the exercise price of a Warrant may be treated as a taxable event under Israeli tax law even if such holder does not receive any cash or other property in connection with the adjustment. Investors should consult their tax advisors regarding the proper treatment of any exercise of and/or adjustments to the Warrants.

Dividends

Dividends distributed by a company to a shareholder who is an Israeli resident individual will generally be subject to income tax at a rate of 25%. However, a 30% tax rate will apply if the dividend recipient is a Controlling Shareholder, as defined above, at the time of distribution or at any time during the preceding 12-month period. If the recipient of the dividend is an Israeli resident corporation, such dividend will generally be exempt from Israeli income tax provided that the income from which such dividend is distributed, derived or accrued within Israel.

S - 20

Dividends distributed by an Israeli resident company to a non-Israeli resident (either an individual or a corporation) are generally subject to Israeli withholding tax on the receipt of such dividends at the rate of 25% (30% if the dividend recipient is a Controlling Shareholder at the time of distribution or at any time during the preceding 12-month period). These rates may be reduced under the provisions of an applicable double tax treaty. For example, under the U.S.-Israel Double Tax Treaty, the following tax rates will apply in respect of dividends distributed by an Israeli resident company to a U.S. resident: (i) if the U.S. resident is a corporation that holds during that portion of the taxable year which precedes the date of payment of the dividend and during the whole of its prior taxable year (if any), at least 10% of the outstanding shares of the voting stock of the Israeli resident paying corporation and not more than 25% of the gross income of the Israeli resident paying corporation for such prior taxable year (if any) consists of certain types of interest or dividends the tax rate is 12.5%; (ii) if both the conditions mentioned in clause (i) above are met and the dividend is paid from an Israeli resident company’s income which was entitled to a reduced tax rate under The Law for the Encouragement of Capital Investments, 1959, the tax rate is 15%; and (iii) in all other cases, the tax rate is 25%. The aforementioned rates under the U.S.-Israel Double Tax Treaty will not apply if the dividend income is attributed to a permanent establishment of the U.S. resident in Israel.

Excess Tax

Individual holders who are subject to tax in Israel (whether any such individual is an Israeli resident or non-Israeli resident) and who have taxable income that exceeds a certain threshold in a tax year (NIS 698,280 for 2023, linked to the Israeli Consumer Price Index) will be subject to an additional tax at the rate of 3% on his or her taxable income for such tax year that is in excess of such amount. For this purpose, taxable income includes taxable capital gains from the sale of securities and taxable income from interest and dividends, subject to the provisions of an applicable double tax treaty.

Estate and Gift Tax

Israel does not currently impose estate or gift taxes if the Israeli Tax Authority is satisfied that the gift was made in good faith and on condition that the recipient of the gift is not a non-Israeli resident.

Foreign Exchange Regulations

Non-residents of Israel who hold our Shares are able to receive any dividends, and any amounts payable upon the dissolution, liquidation and winding up of our affairs, repayable in non-Israeli currency at the rate of exchange prevailing at the time of conversion. However, Israeli income tax is generally required to have been paid or withheld on these amounts. In addition, the statutory framework for the potential imposition of currency exchange control has not been eliminated and may be restored at any time by administrative action.

Material U.S. Federal Income Tax Considerations

The following is a summary of the material U.S. federal income tax consequences relating to the acquisition, ownership, and disposition of the Pre-funded Warrants and ADSs (collectively, the “Securities”) by U.S. Holders, as defined below. This summary addresses solely U.S. Holders who acquire the Securities pursuant to this offering and who hold the Securities as capital assets for tax purposes. This summary is based on current provisions of the Internal Revenue Code of 1986, as amended (the “Code”), current and proposed U.S. Treasury regulations promulgated thereunder, and administrative and judicial decisions as of the date hereof, all of which are subject to change, possibly on a retroactive basis. In addition, this section is based in part upon representations of the depositary and the assumption that each obligation in the Deposit Agreement and any related agreement will be performed in accordance with its terms. This summary does not address all U.S. federal income tax matters that may be relevant to a particular holder or all tax considerations that may be relevant with respect to an investment in the Securities.

S - 21

This summary does not address tax considerations applicable to a holder of the Securities that may be subject to special tax rules including, without limitation, the following:

• dealers or traders in securities, currencies, or notional principal contracts;

• banks, insurance companies, and other financial institutions;

• real estate investment trusts or regulated investment companies;

• persons or corporations subject to an alternative minimum tax;

• tax-exempt organizations;

• traders that have elected mark-to-market accounting;

• corporations that accumulate earnings to avoid U.S. tax;

• pension plans;

• investors that hold the Securities as part of a “straddle,” “hedge,” or “conversion transaction” with other investments;

• persons that actually or constructively own 10 percent or more of our Ordinary Shares outstanding by vote or by value;

• persons that are treated as partnerships or other pass-through entities for U.S. federal income purposes; and

• U.S. Holders whose functional currency is not the U.S. dollar.

This summary does not address the effect of any U.S. federal taxation other than U.S. federal income taxation, and does not include any discussion of state, local, or foreign tax consequences to a holder of the Securities. In addition, this summary does not include any discussion of the U.S. federal income tax consequences to any holder of Securities that is not a U.S. Holder.

You are urged to consult your own tax advisor regarding the foreign and U.S. federal, state, and local income and other tax consequences of an investment in the Securities, including the potential effects of any proposed legislation, if enacted.

For purposes of this summary, a “U.S. Holder” means a beneficial owner of a Security that is for U.S. federal income tax purposes:

• an individual who is a citizen or resident of the U.S.;

• a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes) created or organized in the U.S. or under the laws of the U.S., any state thereof, or the District of Columbia;

• an estate, the income of which is subject to U.S. federal income tax regardless of its source; or

• a trust (1) if (a) a court within the U.S. is able to exercise primary supervision over the administration of the trust and (b) one or more U.S. persons have the authority to control all substantial decisions of the trust or (2) that has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.

If an entity or arrangement that is classified as a partnership for U.S. federal tax purposes holds any Securities, the U.S. federal tax treatment of its partners will generally depend upon the status of the partners and the activities of the partnership. Entities or arrangements that are classified as partnerships for U.S. federal tax purposes and persons holding any Securities through such entities should consult their own tax advisors.

In general, and assuming that all obligations under the Deposit Agreement will be satisfied in accordance with the terms of the Deposit Agreement, if you hold ADSs, you will be treated as the holder of the underlying Ordinary Shares represented by those ADSs for U.S. federal income tax purposes. Accordingly, gain or loss generally will not be recognized if you exchange ADSs for the underlying Ordinary Shares represented by those ADSs.

S - 22

Tax Treatment of Pre-Funded Warrants

Although the law is not completely settled in the area, Pre-funded Warrants should be treated as ADSs for U.S. federal income tax purposes.  Accordingly, a U.S. Holder will not be required to recognize taxable gain or loss upon the exercise of a Pre-funded Warrant for an ADS.  Any person that receives Pre-funded Warrants in this offering should consult their own tax advisor regarding the application of the U.S. federal income tax laws to their particular situation. The remainder of this summary assumes that the Pre-funded Warrants will be treated as ADSs for U.S. federal income tax purposes and references to the ADS shall include Pre-funded Warrants to the extent applicable.

Distributions

If we make any distribution with respect to the Securities, subject to the discussion under “– Passive Foreign Investment Companies” below, the gross amount of any distribution actually or constructively received by a U.S. Holder (through the Depositary) with respect to a Security will generally be taxable to the U.S. Holder as foreign-source dividend income to the extent of our current and accumulated earnings and profits as determined under U.S. federal income tax principles. The amount distributed will include the amount of any Israeli taxes withheld from such distribution, as described above under the caption “Material Tax Considerations-Israeli Tax Considerations.” A U.S. Holder will not be eligible for any dividends received deduction in respect of the dividends paid by us, which deduction is otherwise available to a corporate U.S. Holder in respect of dividends received from a domestic corporation. Distributions in excess of earnings and profits will be non-taxable to the U.S. Holder to the extent of the U.S. Holder’s adjusted tax basis in its Securities. Distributions in excess of such adjusted tax basis will generally be taxable to a U.S. Holder as capital gain from the sale or exchange of property as described below under “-Sale or Other Disposition of ADSs and Pre-funded Warrants.” If we do not report to a U.S. Holder the portion of a distribution that exceeds earnings and profits, then the distribution will generally be taxable as a dividend. The amount of any distribution of property other than cash will be the fair market value of that property on the date of distribution.

Under the Code, certain qualified dividends received by non-corporate U.S. Holders will be subject to U.S. federal income tax at the preferential long-term capital gains of, currently, a maximum of 20%. This preferential income tax rate is applicable only to dividends paid by a “qualified foreign corporation” that is not a PFIC (as defined below under “– Passive Foreign Investment Companies,”) for the year in which the dividend is paid or for the preceding taxable year, and only with respect to the Securities held by a qualified U.S. Holder (i.e., a non-corporate holder) for a minimum holding period (generally 61 days during the 121-day period beginning 60 days before the ex-dividend date) and certain other holding period requirements are met. If such holding period requirements are met, dividends we pay with respect to the Securities generally will be qualified dividend income. However, if we were a PFIC, dividends paid by us to individual U.S. Holders would not be eligible for the reduced income tax rate applicable to qualified dividends. As discussed below under “– Passive Foreign Investment Companies,” we do not anticipate being treated as a PFIC for this year; however, there can be no assurance that we will not be treated as a PFIC for our current taxable or future taxable years. You should consult your own tax advisor regarding the availability of this preferential tax rate under your particular circumstances.

The amount of any distribution paid in a currency other than U.S. dollars (a “foreign currency”), including the amount of any withholding tax thereon, will be included in the gross income of a U.S. Holder in an amount equal to the U.S. dollar value of the foreign currency calculated by reference to the exchange rate in effect on the date of the U.S. Holder’s (or, in the case of ADSs, the depositary’s) receipt of the dividend, actively or constructively, regardless of whether the foreign currency is converted into U.S. dollars. If the foreign currency is converted into U.S. dollars on the date of receipt, a U.S. Holder generally should not be required to recognize a foreign currency gain or loss in respect of the dividend. If the foreign currency received in the distribution is not converted into U.S. dollars on the date of receipt, a U.S. Holder will have a basis in the foreign currency equal to its U.S. dollar value on the date of receipt. Any gain or loss on a subsequent conversion or other disposition of the foreign currency will be treated as U.S. source ordinary income or loss and will not be eligible for the preferential rate applicable to qualified dividend income.

Subject to certain conditions and limitations, any Israeli taxes withheld on dividends may be creditable against a U.S. Holder’s U.S. federal income tax liability, subject to generally applicable limitations. The rules relating to foreign tax credits and the timing thereof are complex. You should consult your own tax advisors regarding the availability of a foreign tax credit in your particular situation.

S - 23

Sale, Exchange, or Other Disposition of ADSs and Pre-funded Warrants

Subject to the discussion under “– Passive Foreign Investment Companies” below, a U.S. Holder that sells or otherwise disposes of its Securities will recognize gain or loss for U.S. federal income tax purposes in an amount equal to the difference between the amount realized on the sale or other disposition and such U.S. Holder’s adjusted basis in the Securities. Such gain or loss generally will be capital gain or loss and will be a long-term capital gain or loss if the U.S. Holder’s holding period of the Securities exceeds one year at the time of the sale or other disposition. Long-term capital gains realized by non-corporate U.S. Holders are generally subject to a preferential U.S. federal income tax rate. In general, gain or loss recognized by a U.S. Holder on the sale or other disposition of the Securities will be U.S. source gain or loss for purposes of the foreign tax credit limitation. However, if we are a PFIC, any such gain will be subject to the PFIC rules, as discussed below, rather than being taxed as a capital gain. As discussed below in “-Passive Foreign Investment Companies,” we do not anticipate being a PFIC for this year; however, there can be no assurance that we will not be treated as a PFIC for our current taxable year and future taxable years.

If a U.S. Holder receives foreign currency upon a sale or exchange of the Securities, gain or loss will be recognized in the manner described above under “– Distributions.” However, if such foreign currency is converted into U.S. dollars on the date received by the U.S. Holder, the U.S. Holder generally should not be required to recognize any foreign currency gain or loss on such conversion.

As discussed above under the heading “Material Tax Considerations-Israeli Tax Considerations-Taxation of Shareholders,” a U.S. Holder who holds Securities through an Israeli broker or other Israeli intermediary may be subject to Israeli withholding tax on any capital gains recognized on a sale or other disposition of the Securities. Any Israeli tax paid under circumstances in which an exemption from (or a refund of or a reduction in) such tax was available will not be creditable for U.S. federal income tax purposes. U.S. Holders are advised to consult their Israeli broker or intermediary regarding the procedures for obtaining an exemption or reduction.

Medicare Tax on Unearned Income

Non-corporate U.S. Holders whose income exceeds certain thresholds are required to pay an additional 3.8% tax on their net investment income, which includes dividends paid on the Securities and capital gains from the sale or other disposition of the Securities.

Passive Foreign Investment Companies

Although we do not anticipate being treated as a passive foreign investment company (“PFIC”) for this year, the treatment of the Company as a PFIC is  based on the value and composition of our assets, and no assurance can be given that we will not be treated as a PFIC for U.S. federal income tax purposes for our current taxable year or future taxable years. We will be considered a PFIC for any taxable year if:

• at least 75% of our gross income for such taxable year is passive income; or

• at least 50% of the value of our assets (based on an average of the fair market values of the assets determined at the end of each quarter during a taxable year) is attributable to assets that produce or are held for the production of passive income.

For purposes of the above calculations, if we own, directly or indirectly, 25% or more of the total value of the outstanding shares of another corporation, we will be treated as if we (a) held a proportionate share of the assets of such other corporation and (b) received a proportionate share of the income of such other corporation directly. Passive income generally includes, among other things, dividends, interest, rents, royalties and certain capital gain, but generally excludes rents and royalties that are derived in the active conduct of a trade or business and which are received from a person other than a related person.

S - 24

A separate determination must be made each taxable year as to whether we are a PFIC (after the close of each such taxable year). Because the value of our assets for purposes of the asset test will generally be determined by reference to the market price of the ADSs and Pre-funded Warrants, our PFIC status will also depend in large part on the market price of the Securities, which may fluctuate significantly.

If we are a PFIC for any year during which a U.S. Holder holds any Securities, we generally will be treated as a PFIC with respect to such U.S. Holder for all succeeding years during which such U.S. Holder holds the Securities, unless we cease to be a PFIC and such U.S. Holder makes a “deemed sale” election with respect to the Securities that such U.S. Holder holds. For this purpose, a U.S. Holder that acquired an ADS through the exercise of a Pre-funded Warrant will be treated as holding such ADS for the period during which such Pre-funded Warrant was held. A U.S. Holder that makes such an election will be deemed to have sold the Securities it holds at their fair market value on the last day of the last taxable year in which we qualified as a PFIC, and any gain from such deemed sale will be subject to the U.S. federal income tax treatment described below. After the deemed sale election, the Securities with respect to which the deemed sale election was made will not be treated as shares in a PFIC unless we subsequently become a PFIC.

For each taxable year for which we are treated as a PFIC with respect to a U.S. Holder, such U.S. Holder will be subject to special tax rules with respect to any “excess distribution” it receives and any gain it realizes from a sale or other disposition (including a pledge) of the Securities, unless it makes a “mark-to-market” election or a “qualified electing fund” election discussed below. Distributions that a U.S. Holder receives in a taxable year that are greater than 125% of the average annual distributions it received during the shorter of the three preceding taxable years or its holding period for the Securities will be treated as an excess distribution. Under these special tax rules, if a U.S. Holder receives any excess distribution or realizes any gain from a sale or other disposition of the Securities:

• the excess distribution or gain will be allocated ratably over the U.S. Holder’s holding period for the Securities;

• the amount of excess distribution or gain allocated to the current taxable year, and any taxable year before the first taxable year in which we were a PFIC, must be included in the U.S. Holder’s gross income (as ordinary income) for the tax year of the sale or disposition; and

• the amount allocated to each other year will be subject to the highest marginal tax rate in effect with respect to such U.S. Holder for that year and the interest charge generally applicable to underpayments of tax will be imposed on the resulting tax attributable to such amounts allocated to each other year.

The tax liability for amounts allocated to years before the year of disposition or “excess distribution” cannot be offset by any losses for such years. Additionally, any gains realized on the sale of the Securities cannot be treated as capital gains.

If we are treated as a PFIC with respect to a U.S. Holder for any taxable year, to the extent any of our subsidiaries are also PFICs, such U.S. Holder will be deemed to own its proportionate share of any such subsidiaries that are PFICs, and such U.S. Holder may be subject to the rules described in the preceding two paragraphs with respect to the shares of such subsidiaries that are PFICs it will be deemed to own. As a result, a U.S. Holder may incur liability for any “excess distribution” described above if we receive a distribution from such subsidiaries that are PFICs or if we dispose of, or are deemed to dispose of, any shares in such subsidiaries that are PFICs. You should consult your own tax advisor regarding the application of the PFIC rules to any of our subsidiaries.

S - 25

Alternatively, a U.S. Holder of “marketable stock” (as defined below) in a PFIC may make a mark-to-market election for such stock to elect out of the general tax treatment for PFICs discussed above. If a U.S. Holder makes a mark-to-market election for the ADSs, such U.S. Holder will include in income for each year we are a PFIC an amount equal to the excess, if any, of the fair market value of the ADSs as of the close of such U.S. Holder’s taxable year over such U.S. Holder’s adjusted basis in such ADSs. A U.S. Holder is allowed a deduction for the excess, if any, of the adjusted basis of the ADSs over their fair market value as of the close of the taxable year. However, deductions are allowable only to the extent of any net mark-to-market gains on the ADSs included in a U.S. Holder’s income for prior taxable years. Amounts included in a U.S. Holder’s income under a mark-to-market election, as well as gain on the actual sale or other disposition of the ADSs, are treated as ordinary income. Ordinary loss treatment also applies to the deductible portion of any mark-to-market loss on the ADSs, as well as to any loss realized on the actual sale or disposition of the ADSs to the extent the amount of such loss does not exceed the net mark-to-market gains previously included for the ADSs. A U.S. Holder’s basis in the ADSs will be adjusted to reflect any such income or loss amounts. If a U.S. Holder makes a valid mark-to-market election, the tax rules that apply to distributions by corporations that are not PFICs will apply to distributions by us, except the lower applicable tax rate for qualified dividend income will not apply. If we cease to be a PFIC when a U.S. Holder has a mark-to-market election in effect, gain or loss realized by such U.S. Holder on the sale of the ADSs will be a capital gain or loss and taxed in the manner described above under “– Sale, Exchange, or Other Disposition of ADSs and Pre-funded Warrants.”

The mark-to-market election is available only for “marketable stock,” which is a stock that is traded in other than de minimis quantities on at least 15 days during each calendar quarter, or regularly traded, on a qualified exchange or another market, as defined in applicable U.S. Treasury regulations. Any trades that have as their principal purpose meeting this requirement will be disregarded. The ADSs are listed on Nasdaq and, accordingly, provided the ADSs are regularly traded, the mark-to-market election will be available to a U.S. Holder of ADSs if we are a PFIC. Once made, the election cannot be revoked without the consent of the IRS unless the ADSs cease to be marketable stock. If we are a PFIC for any year in which the U.S. Holder owns the ADSs but before a mark-to-market election is made, the interest charge rules described above will apply to any mark-to-market gain recognized in the year the election is made. If any of our subsidiaries are or become PFICs, the mark-to-market election will not be available with respect to the shares of such subsidiaries that are treated as owned by a U.S. Holder. Consequently, a U.S. Holder could be subject to the PFIC rules with respect to income of the lower-tier PFICs the value of which already had been taken into account indirectly via mark-to-market adjustments. You should consult your own tax advisors as to the availability and desirability of a mark-to-market election, as well as the impact of such election on interests in any lower-tier PFICs.

In certain circumstances, a U.S. Holder of stock in a PFIC can make a “qualified electing fund” election to mitigate some of the adverse tax consequences of holding stock in a PFIC by including in income its share of the corporation’s income on a current basis. However, we do not currently intend to prepare or provide the information that would enable a U.S. Holder to make a qualified electing fund election.

Unless otherwise provided by the U.S. Treasury, each U.S. shareholder of a PFIC is required to file an annual information return on IRS Form 8621 (Information Return by a Shareholder of a Passive Foreign Investment Company or Qualifying Electing Fund) containing such information as the U.S. Treasury may require. A U.S. Holder’s failure to file such annual information return could result in the imposition of penalties and the extension of the statute of limitations with respect to U.S. federal income tax. You should consult your own tax advisors regarding the requirements of filing such information returns under these rules, taking into account the uncertainty as to whether we are currently treated as or may become a PFIC.

YOU ARE STRONGLY URGED TO CONSULT YOUR OWN TAX ADVISOR REGARDING THE IMPACT AND APPLICATION OF THE PFIC RULES ON YOUR INVESTMENT IN THE SECURITIES.

Backup Withholding and Information Reporting

Payments of dividends with respect to the Securities and the proceeds from the sale, retirement, or other disposition of the Securities made by a U.S. paying agent or other U.S. intermediary will generally be reported to the IRS and to the U.S. Holder as may be required under applicable U.S. Treasury regulations. We, or an agent, a broker, or any paying agent, as the case may be, may be required to withhold tax (backup withholding), currently at the rate of 24%, if a non-corporate U.S. Holder that is not otherwise exempt fails to provide an accurate taxpayer identification number and comply with other IRS requirements concerning information reporting. Certain U.S. Holders (including, among others, corporations and tax-exempt organizations) are not subject to backup withholding. Backup withholding is not an additional tax. Any amount of backup withholding withheld may be used as a credit against your U.S. federal income tax liability or may be refunded provided that the required information is timely furnished to the IRS. U.S. Holders should consult their own tax advisors as to their qualification for exemption from backup withholding and the procedure for obtaining an exemption.

You should consult your own tax advisors regarding the backup withholding tax and information reporting rules.

Foreign Asset Reporting 

Certain U.S. Holders who are individuals are required to report information relating to an interest in the Securities, subject to certain exceptions (including an exception for shares held in accounts maintained by financial institutions) by filing IRS Form 8938 (Statement of Specified Foreign Financial Assets) with their federal income tax return. U.S. Holders are urged to consult their tax advisors regarding their information reporting obligations, if any, with respect to their ownership and disposition of the Securities.

REDHILL BIOPHARMA LTD.

Overview

We are a specialty biopharmaceutical company, primarily focused on gastrointestinal (“GI”) and infectious diseases. Our primary goal is to become a leading specialty biopharmaceutical company through our commercial presence in the U.S. that supports current commercialization of products approved for marketing and potential future commercialization of our therapeutic candidates, if approved.

We are currently focused primarily on the commercialization in the U.S. of the GI-related products, Movantik^® (naloxegol), Talicia^® (omeprazole, amoxicillin, and rifabutin) and Aemcolo^® (rifamycin).

In addition, we continue to develop our pipeline of clinical-stage therapeutic candidates, including, among others, the study of our therapeutic candidates, opaganib (ABC294640) and RHB-107 (upamostat), as potential treatments for COVID-19. We look for opportunities to leverage our commercial presence and capabilities in the U.S. to support the potential future launch of our therapeutic candidates currently under development, if approved by the U.S. Food and Drug Administration (“FDA”), or any FDA-approved products that we may acquire or license in the future.

Our therapeutic candidates are designed to exhibit greater efficacy and/or provide improvements over existing drugs in various ways, including by one or more of the following: by improving their safety profile, reducing side effects, lowering the number of administrations, using a more convenient administration form or providing a cost advantage. Our current pipeline consists of six therapeutic candidates, most of which are in late-stage clinical development.

We generate our pipeline of therapeutic candidates by identifying, validating and in-licensing or acquiring products that are consistent with our product and corporate strategy and that have the potential to exhibit a favorable probability of therapeutic and commercial success. We have one product that we primarily developed internally which has been approved for marketing and, to date, none of our therapeutic candidates has generated meaningful revenues. We plan to commercialize our therapeutic candidates, upon approval, if any, through licensing and other commercialization arrangements outside the U.S. with pharmaceutical companies on a global and territorial basis or, in the case of commercialization in the U.S., independently with our dedicated commercial operations or in potential partnership with other commercial-stage companies. We also evaluate, on a case-by-case basis, co-development, co-promotion, licensing and similar arrangements.

U.S. and global COVID-19 studies with opaganib

Opaganib, a new chemical entity, is a proprietary, first-in-class, orally-administered, sphingosine kinase-2 (SK2) selective inhibitor with observed anticancer, anti-inflammatory, and antiviral activities, targeting multiple oncology, viral, inflammatory, and gastrointestinal indications.

In July 2020, we initiated a global Phase 2/3 clinical trial evaluating opaganib in hospitalized patients with severe COVID-19 pneumonia. This global multi-center, randomized, double-blind, parallel-arm, placebo-controlled trial enrolled a total of 475 patients requiring hospitalization and treatment with supplemental oxygen. The study has been approved in ten countries. On July19, 2021, we announced that we had completed treatment and follow-up of all 475 patients in the trial and that top-line results are expected in the coming weeks. The primary endpoint of the trial is the proportion of patients breathing room air without oxygen support by Day 14. Additional important outcome measures, such as time to discharge from hospital, improvement according to the World Health Organization Ordinal Scale for Clinical Improvement and incidence of intubation and mortality, will also be captured in the follow-up period of up to six weeks. The trial has received four independent DSMB recommendations to continue following unblinded safety reviews and a futility review.

In December 2020, we announced that our randomized, double-blind, placebo-controlled U.S. Phase 2 trial with opaganib in patients hospitalized with COVID-19 pneumonia demonstrated preliminary top-line positive safety and efficacy data. The trial, which was not powered for statistical significance, enrolled 40 patients requiring hospitalization and supplemental oxygen.

2

In June 2021, we announced the presentation of the findings from the 40-patient U.S. phase 2 trial, including:

•          50.0% of patients treated with opaganib (n=22) reached room air by Day 14 compared to 22.2% in the placebo group (n=18). The benefit of reaching room air by Day 14 for patients on opaganib was maintained regardless of whether or not the patients were also receiving dexamethasone and/or remdesivir.

•          86.4% of patients treated with opaganib were discharged from hospital by Day 14 compared to 55.6% of patients treated with placebo.

•          Median time to discharge was 6 days for the opaganib group compared to 7.5 days for the placebo group.

•          81.8% of opaganib patients achieved a 2-point improvement in the WHO Ordinal Scale compared to 55.6% of patients in the placebo group – achieved in a median time of 6 days versus 7.5 days, respectively.

•          No significant differences in safety-related measures between the two groups (with diarrhea being the main treatment-emergent difference in tolerability) were observed.

Opaganib was originally developed by U.S.-based Apogee Biotechnology Corp. (“Apogee”) and completed multiple successful preclinical studies in oncology, inflammation, GI, and radioprotection models, as well as a Phase 1 clinical trial in cancer patients with advanced solid tumors and an additional Phase 1 trial in multiple myeloma.

Opaganib received orphan drug designation from the FDA for the treatment of cholangiocarcinoma and is also being evaluated in a Phase 2a trial in advanced cholangiocarcinoma and in a Phase 2 trial in prostate cancer.

Preclinical data have demonstrated both anti-inflammatory and antiviral activities of opaganib, demonstrating the potential to reduce inflammatory lung disorders, such as pneumonia, and mitigate pulmonary fibrotic damage. Opaganib demonstrated potent antiviral activity against SARS-CoV-2, the virus that causes COVID-19, completely inhibiting viral replication in an in vitro model of human lung bronchial tissue. Additionally, preclinical in vivo studies have demonstrated that opaganib decreased fatality rates from influenza virus infection and ameliorated Pseudomonas aeruginosa-induced lung injury by reducing the levels of IL-6 and TNF-alpha in bronchoalveolar lavage fluids.

In June 2021, we announced that preliminary results from a preclinical study with opaganib demonstrate potent inhibition of COVID-19 variants of concern by opaganib. Working with the University of Louisville Center for Predictive Medicine, opaganib was studied in a 3D tissue model of human bronchial epithelial cells (EpiAirway™) to evaluate the in vitro efficacy of opaganib in inhibiting the Beta (South African) and Gamma (Brazilian) SARS-CoV-2 variants. Preliminary results showed potent inhibition of both the Beta and Gamma variants by opaganib at non-cytotoxic doses. Based on opaganib’s unique host-targeted mechanism and the preliminary results of this study, we believe opaganib is likely to also maintain its activity against emerging variants, including the Delta and Delta Plus variants.

Under a compassionate use program, seven COVID-19 patients (as classified by the WHO ordinal scale) were treated with opaganib in a leading hospital in Israel. Analysis of treatment outcomes from the five patients included in the final published analysis suggested substantial benefit to patients treated with opaganib under compassionate use in both clinical outcomes and inflammatory markers as compared to a retrospective matched case-control group from the same hospital. All patients in the opaganib-treated group were discharged from hospital on room air without requiring intubation and mechanical ventilation, whereas 33% of the matched case-control group required intubation and mechanical ventilation. Median time to weaning from high-flow nasal cannula was reduced to 10 days in the opaganib-treated group, as compared to 15 days in the matched case-control group.

3

The development of opaganib for indications non-related to COVID-19 has been supported by grants and contracts from U.S. federal and state government agencies awarded to Apogee, including from the U.S. National Cancer Institute (NCI), Biomedical Advanced Research and Development Authority (BARDA), the U.S. Department of Defense and the FDA Office of Orphan Products Development. In September 2020, Apogee was awarded a grant from Pennsylvania’s COVID-19 Vaccines, Treatments and Therapies Program, which supports the rapid advancement of promising novel COVID-19 therapies.

In May 2021, we announced receipt of a Notice of Allowance for a U.S. patent application covering the use of opaganib for the treatment of COVID-19 with a term extending until at least 2041. We also previously announced that we had signed collaborations with several U.S., European and Canadian suppliers, including with Cosmo Pharmaceuticals for large-scale ramp-up of opaganib manufacturing, further strengthening manufacturing capabilities and capacity of opaganib.

In view of the completion of enrollment, treatment and follow up for our global Phase 2/3 clinical trial evaluating opaganib in hospitalized patients with severe COVID-19 pneumonia, we maintain ongoing discussions with the FDA, the European Medicines Agency (EMA) and other regulators, on potential pathways to approval for opaganib with a focus on those countries currently most affected by COVID-19. The next steps will be guided by the results of the global Phase 2/3 trial.

Discussions are also ongoing with potential partners who are interested in the rights to opaganib in various countries.

The regulatory path, including potential submissions of emergency use applications in those countries, is subject to the data generated by the ongoing Phase 2/3 trial, as well as the specific requirements in each country. The strength of the safety and efficacy data generated from the opaganib studies will be key to regulatory applications. Additional studies to support the potential of such applications and the use or marketing of opaganib are likely to be required. For example, the FDA has indicated we will need to complete additional studies to support applications in the U.S. Evaluations and discussions continue with the FDA, EMA and regulators in other countries.

Our Approved and Commercial Products in the U.S.

We have established the headquarters of our U.S. commercial operations in Raleigh, North Carolina. Our U.S. operations promote Movantik^® for opioid-induced constipation in adults, Talicia^® for the treatment of H. pylori infection in adults and Aemcolo^® for the treatment of travelers’ diarrhea in adults. We also expect our U.S. operations to serve as the platform for potential launch of our proprietary, late-clinical stage therapeutic candidates in the U.S., if approved by the FDA, and potential in-licensed or acquired commercial-stage products in the U.S.

During 2020, we expanded our sales force from approximately 40 sales representatives to approximately 100 sales representatives. We commercially launched Talicia^® in March 2020 and initiated our commercialization activities for Movantik^® in April 2020.

Movantik^®

In April 2020, we acquired from AstraZeneca AB (“AstraZeneca”) worldwide rights (excluding Europe and Canada) to commercialize and develop Movantik^® (naloxegol), pursuant to a license agreement, dated February 23, 2020 (the “AstraZeneca License Agreement”), and in October 2020 we obtained the rights to commercialize and develop Movantik^® in Israel. Movantik^® is a proprietary once-daily oral peripherally acting mu-opioid receptor antagonist (PAMORA) approved by the FDA for the treatment of opioid-induced constipation (OIC) in adult patients with chronic non-cancer pain, including patients with chronic pain related to prior cancer or its treatment who do not require frequent (e.g. weekly) opioid dosage escalation. We initiated our U.S. commercialization activities for Movantik^® in April 2020.

4

Movantik^® received FDA approval on September 16, 2014, for the treatment of OIC in adult patients with chronic non-cancer pain. Its label was later updated to include patients with chronic pain related to prior cancer or its treatment who do not require frequent (e.g. weekly) opioid dosage escalation. In the AstraZeneca License Agreement, we agreed to assume responsibility for completing any postmarketing requirements or commitments that may be required to retain approval. Accordingly, we will be required to continue the postmarketing observational epidemiologic study to evaluate the major adverse cardiovascular events (MACE) of Movantik^®.

In August 2020, we announced that we had replaced the 2015 Movantik^® co-commercialization agreement with Daiichi Sankyo, Inc. (Daiichi Sankyo) (assigned under the agreement with AstraZeneca), with a new royalty-bearing agreement. Under the terms of the new agreement, we bear all responsibilities and costs for commercializing Movantik^® in the U.S. During the term of the new agreement, we pay Daiichi Sankyo a mid-teen royalty rate on net sales of Movantik^® in the U.S., in addition to three annual lump sum payments, starting in the fourth quarter of 2021 and ending in 2023.

In July 2020, we amended the AstraZeneca License Agreement, whereby the parties agreed to postpone the non-contingent payment of $15.0 million by us to December 2021 and to increase the amount due by $0.5 million.

In July 2021, we announced that one of America’s largest payors, serving many Blue Cross and Blue Shield Plans and more than 30 million members, had added Movantik^® as a preferred brand with no restrictions to its National Formulary and as a preferred brand on its other commercial formularies starting July 1, 2021. Movantik^®’s total commercial coverage now extends to 152 million American patient lives.

Talicia^® (omeprazole, magnesium, amoxicillin, and rifabutin) delayed-release capsules 10 mg/250 mg/12.5 mg

Talicia^® is designed to address the high resistance of H. pylori bacteria to the antibiotics commonly used in current standard-of-care therapies. Talicia^®’s approval was supported, in part, by the results of two positive Phase 3 trials in the U.S. for the treatment of H. pylori-positive adult patients complaining of epigastric pain and/or discomfort. The confirmatory Phase 3 trial of Talicia^® demonstrated 84% eradication of H. pylori infection with Talicia^® vs. 58% in the active comparator arm (p<0.0001). Further, in an analysis of data from this trial, it was observed that subjects with measurable blood levels of drug at visit 3 (approximately day 13) had response rates of 90.3% in the Talicia^® arm vs. 64.7% in the active comparator arm.

We believe that Talicia^® may offer a significant benefit over other currently approved drugs in part because of the resistance profile demonstrated in our Phase 3 program, which showed no bacterial resistance to rifabutin and high resistance to clarithromycin and metronidazole.

Talicia^® is the first product we developed that was approved for marketing in the U.S. Talicia^® was approved by the FDA on November 1, 2019, and we launched Talicia^® in the U.S. in March 2020.

In November 2014, Talicia^® was granted Qualified Infectious Disease Product (QIDP) designation by the FDA. Under its QIDP designation, Talicia^® is eligible for an additional five years of U.S. market exclusivity, on top of the standard exclusivity period, for a total of eight years of market exclusivity.

In July 2021, we announced that OptumRx, part of the UnitedHealth Group - a leader in healthcare coverage serving more than 26 million Americans, had added Talicia to its Commercial Formulary as an unrestricted brand for H. pylori treatment, effective July 1, 2021. Patient access to Talicia now extends to greater than 8 out of 10 covered U.S. commercial lives.

Aemcolo^®

Aemcolo^®, containing 194 mg of rifamycin, is an orally administered, minimally absorbed antibiotic that is delivered to the colon, approved by the FDA in 2018 for the treatment of travelers’ diarrhea caused by non-invasive strains of E. coli in adults (“Travelers’ Diarrhea”). In October 2019, we entered into a license agreement with a wholly-owned subsidiary of Cosmo Pharmaceuticals N.V. (“Cosmo”) pursuant to which we were granted exclusive rights to commercialize Aemcolo^® in the U.S. In December 2019, we launched the commercialization of Aemcolo^® in the U.S.

Aemcolo^® received FDA approval on November 16, 2018, for the treatment of travelers’ diarrhea caused by noninvasive strains of E. coli in adults. Cosmo transferred the Aemcolo^® New Drug Application (NDA) and the IND to RedHill Biopharma Inc., which were accepted on November 27, 2019. This acceptance also includes a commitment to complete any postmarketing requirements or commitments related to the NDA. There are two pediatric studies that are required to be completed to satisfy the PREA requirements:

• Conduct a randomized, placebo-controlled study to evaluate the safety, tolerability, and efficacy of Aemcolo^® (rifamycin) for the treatment of travelers’ diarrhea in children from 6 to 11 years of age.

• Conduct a randomized, placebo-controlled study to evaluate the safety, tolerability, and efficacy of Aemcolo^® (rifamycin) for the treatment of travelers’ diarrhea in children from 12 to 17 years of age.

In October 2017, the FDA granted QIDP and Fast Track designations for Aemcolo^®. With the QIDP designation, intended for antibacterial or antifungal drugs that treat serious or life-threatening infections, together with new chemical entity (NCE) designation, Aemcolo^® enjoys marketing exclusivity until 2028. Due to the significant decrease in travel as a result of the pandemic, the travelers’ diarrhea market has been significantly impacted, and we have not generated meaningful revenues from the sale of Aemcolo^®. We do not expect Aemcolo^® to generate meaningful revenues until U.S. international travel returns to pre-COVID-19 pandemic levels, if at all, and there can be no assurance that we will generate meaningful revenues upon return of U.S. international travel to pre-pandemic levels.

RedHill has implemented plans, including re-launching active field promotion of Aemcolo®, to support, and build on, the initial momentum that Aemcolo® was generating pre-COVID-19 travel restrictions.

We continue to pursue the acquisition of additional commercial products, including, without limitation, through licensing or promotion transaction, asset purchase, joint venture with, acquisition of, or merger with or other business combination with, companies with rights to commercial GI and other relevant assets and are continuously working to expand U.S.-managed care access and coverage to our commercial products, where appropriate. We plan to pursue such opportunities in the U.S. and, if available, in other jurisdictions; however, we intend to focus our commercial activities in the U.S.

Recent Developments on our Therapeutic Product Candidates

RHB‑204

RHB‑204 is a patented fixed-dose oral capsule containing a combination of three antibiotics developed for the treatment of pulmonary Mycobacterium avium Complex (MAC) disease in adults with nodular bronchiectasis (also referred to hereafter as pulmonary nontuberculous mycobacteria (NTM) disease caused by MAC). Each capsule contains clarithromycin, clofazimine, and rifabutin, at doses distinct from RHB‑104.

In November 2020, we initiated our Phase 3 trial to evaluate the efficacy and safety of RHB-204 in adults with pulmonary NTM disease caused by MAC infection. This multi-center, randomized, double-blind, two-part, placebo-controlled, parallel-group Phase 3 trial is planned to be conducted at up to 40 sites across the U.S. Study endpoints include sputum culture conversion at month six of treatment with RHB-204, compared to placebo and Quality of Life questionnaire, including improvements in physical functioning, respiratory symptoms and fatigue. An interim sample size re-estimate is planned once the study reaches approximately 50% enrollment.

6

In January 2017, we announced that RHB‑204 had been granted QIDP designation by the FDA for the treatment of pulmonary NTM disease, including eligibility for Priority Review, Accelerated Approval and an extended market exclusivity period, if approved for marketing in the U.S. In October 2020, we announced that the FDA granted RHB-204 Orphan Drug designation which, together with the QIDP designation will extend U.S. market exclusivity to a total of 12 years, if RHB-204 is approved by the FDA. In January 2021, we announced that the FDA granted RHB-204 Fast Track designation, allowing RedHill access to early and frequent communications with the FDA, to expedite the RHB-204 development program, and to a rolling review of an NDA.

RHB-107

RHB-107 (formerly Mesupron) (INN: upamostat) is a proprietary, first-in-class, orally-administered potent inhibitor of several serine proteases. We are developing this investigational new drug as a potential treatment for symptomatic COVID-19 patients that do not require hospitalization. In addition, we believe RHB-107 has potential in targeting cancer, inflammatory lung diseases and gastrointestinal diseases. In November 2020, we announced that the FDA had cleared our IND application for a U.S. Phase 2/3 trial evaluating RHB-107 in non-hospitalized patients with symptomatic COVID-19 who do not require supplemental oxygen. In December 2020, we submitted an amendment to the protocol for that trial, addressing FDA comments. In February 2021, we announced that the first patient had been dosed in the trial. This multicenter, randomized, double-blind, placebo-controlled, parallel-group trial will evaluate the safety and efficacy of RHB-107. The first part of the trial is designed for dose selection and is planned to enroll 60 patients. The second part of the trial is planned to enroll 250 patients and will evaluate time to sustained recovery from illness as the primary endpoint. Each patient will be tested for specific viral strain. Several secondary and exploratory endpoints will also be assessed.

In May 2021, we announced the receipt of a notice of allowance from the USPTO covering RHB-107 as a method for the treatment of COVID-19 caused by the SARS-CoV-2 virus.

Expanded Access Program (EAP)

We have adopted an Expanded Access Program (“EAP”), allowing patients with life-threatening diseases potential access to our investigational new drugs that have not yet received regulatory marketing approval. Expanded access (sometimes referred to as “compassionate use”) is possible outside of our clinical trials, under certain eligibility criteria, when a certain investigational new drug is needed to treat a life-threatening condition and when there is some clinical evidence suggesting that the drug might be effective for that condition. Patients who qualify for our EAP do not meet the eligibility criteria or are incapable of participating in our clinical trials for such therapeutic candidates or there is no clinical trial accessible to such patients. Following the adoption of the program, we continue to receive patient requests to obtain access to our investigational drugs. Subject to the evaluation of eligibility and all other necessary regulatory, reporting and other conditions and approvals required in all relevant jurisdictions, we provide certain patients with an investigational new drug under the EAP.

January 2021 Underwritten Offering

On January 14, 2021, we closed an underwritten offering of 3,188,776 ADSs at a public offering price of $7.84 per ADS, for total net proceeds of approximately $23.1 million, after deducting underwriting discounts and commissions and approximated offering expenses payable by us in connection with the offering.

March 2021 Underwritten Offering

On March 4, 2021, we closed an underwritten offering of 4,375,000 ADSs at a public offering price of $8.00 per ADS, for total net proceeds of approximately $32.8 million, after deducting underwriting discounts and commissions and approximated offering expenses payable by us in connection with the offering. On March 11, 2021, and on March 16, 2021, the underwriter exercised its overallotment option and accordingly we issued an additional 272,433 ADSs for total net proceeds of approximately $2.0 million, after deducting underwriting discounts and commissions.

Recent Developments

In March 2021 we announced that RedHill Biopharma Inc., AstraZeneca AB and AstraZenca Pharmaceuticals LP and Nektar Therapeutics entered into a settlement and license agreement with MSN Pharmaceuticals, Inc. and MSN Laboratories PVT. LTD. (“MSN”) resolving their patent litigation in the U.S. in response to MSN’s Abbreviated New Drug Application (“ANDA”) seeking approval by the US. FDA to market a generic version of Movantik^®. Under the terms of the settlement agreement, MSN may not sell a generic version of Movantik^® in the U.S. until October 1, 2030 (subject to U.S. FDA approval) or earlier under certain circumstances. The parties to the settlement agreement have also agreed to file a stipulation and order of dismissal with the U.S. District Court for the District of Delaware which will conclude this litigation with respect to MSN. As required by law, the parties will submit the settlement agreement to the U.S. Federal Trade Commission and the U.S. Department of Justice for review. The settlement with MSN did not end RedHill’s ongoing litigation against the other two ANDA filers.

In July 2021, we announced that RedHill Biopharma Inc., AstraZeneca AB and AstraZeneca Pharmaceuticals LP and Nektar Therapeutics have entered into a settlement and license agreement with Apotex, Inc. and Apotex Corp. (“Apotex”) resolving their patent litigation in the U.S. in response to Apotex’s Abbreviated New Drug Application (“ANDA”) seeking approval by the US. FDA to market a generic version of Movantik^®. Under the terms of the settlement agreement, Apotex may not sell a generic version of Movantik^® in the U.S. until October 1, 2030 (subject to U.S. FDA approval) or earlier under certain circumstances. The parties to the settlement agreement also agreed to file a stipulation and order of dismissal with the U.S. District Court for the District of Delaware which will conclude this litigation with respect to Apotex. As required by law, the parties will submit the settlement agreement to the U.S. Federal Trade Commission and the U.S. Department of Justice for review. The settlement with Apotex did not end RedHill’s ongoing litigation against the other one ANDA filer.

 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, including the “Item 3. Key Information – Risk Factors” in our Annual Report on Form 20-F for the year-ended December 31, 2020, in full.

● Our pursuit of treatments for SARS-CoV-2 (the virus that causes COVID-19) infection in patients entails a high level of uncertainty. We have conducted limited testing of both opaganib and RHB-107 and cannot assure you that either of them will prove to be a safe and effective treatment for COVID-19 or will be approved for marketing or Emergency Use Authorization by the FDA or other regulatory authorities.

● If we are successful in developing a COVID-19 therapeutic, we may need to devote significant resources to our manufacturing scale-up and large-scale deployment, including for use by the U.S. or other governments. If one of our COVID-19 therapeutic candidates is approved for marketing we may also need to devote significant resources to further expand our U.S. sales and marketing activities and increase or maintain personnel to accommodate sales in the U.S.

● The ongoing COVID-19 pandemic may adversely affect our business, revenues, results of operations and financial condition.

● Our current working capital is not sufficient to commercialize our current commercial products or to complete the research and development with respect to any or all of our therapeutic candidates. We may need to raise additional capital to achieve our strategic objectives and to execute our business plans, and our failure to raise sufficient capital or on favorable terms would significantly impair our ability to fund the commercialization of our current commercial products, therapeutic candidates, or the products we may commercialize or promote in the future, attract development or commercial partners or retain key personnel, and to fund operations and develop our therapeutic candidates.

8

● Our long-term capital requirements are subject to numerous risks.

● Our term loan facility imposes significant operating and financial restrictions on us, which may prevent us from capitalizing on business opportunities and may restrict our operational flexibility, and our failure to comply with the restrictive covenants in our term loan facility could have a material adverse effect on our business.

● We may be unable to generate sufficient cash flow to make the required payments under the term loan facility or to adhere to other requirements under the term loan facility.

● The indebtedness under our term loan facility is secured by substantially all of the current and future assets of RedHill Biopharma Inc., all of our assets related in any material respect to Talicia^®, and all of the equity interests of RedHill Biopharma Inc. As a result of these security interests, such assets would only be available to satisfy claims of our general creditors or t holders of our equity securities if we were to become insolvent to the extent the value of such assets exceeded the amount of our indebtedness and other obligations. In addition, the existence of these security interests may adversely affect our financial flexibility.

● If we or our future development or commercialization partners are unable to obtain or maintain the FDA or other foreign regulatory clearance and approval for our commercial products or therapeutic candidates, we or our commercialization partners will be unable to commercialize our current commercial products, products we may commercialize or promote in the future or our therapeutic candidates, upon approval, if any.

RISK FACTORS

An investment in our securities involves a high degree of risk. Our business, financial condition or results of operations could be adversely affected by any of these risks. You should carefully consider the risk factors discussed under the caption "Item 3: Key Information - Risk Factors" in our Annual Report on Form 20-F for the year ended December 31, 2020, and in any other filing we make with the SEC subsequent to the date of this prospectus, each of which is incorporated herein by reference, and in any supplement to this prospectus, before making your investment decision. The risks and uncertainties we have described are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our operations. Past financial performance may not be a reliable indicator of future performance, and historical trends should not be used to anticipate results or trends in future periods. If any of these risks actually occurs, our business, business prospects, financial condition or results of operations could be seriously harmed. This could cause the trading price of the ADSs to decline, resulting in a loss of all or part of your investment. Please also read carefully the section below entitled “Forward-Looking Statements.”

FORWARD-LOOKING STATEMENTS

This prospectus, including the information incorporated by reference into this prospectus, contains, and any prospectus supplement may include forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995.

• the scope of protection we are able to establish and maintain for intellectual property rights covering our therapeutic candidates and our ability to operate our business without infringing or violating the intellectual property rights of others;

• parties from whom we license or acquire our intellectual property defaulting in their obligations toward us;

• the failure by a licensor or a partner of ours to meet their respective obligations under our acquisition, in-license or other development or commercialization agreements or renegotiate the obligations under such agreements, or if other events occur that are not within our control, such as bankruptcy of a licensor or a partner;

• our ability to implement and maintain network systems and controls that are effective at preventing cyber-attacks, malware intrusions, malicious viruses and ransomware threats; and

• the impact of the political and security situation in Israel on our business.

We caution you to carefully consider these risks and not to place undue reliance on our forward-looking statements. Except as required by law, we assume no responsibility for updating any forward-looking statements.

DESCRIPTION OF SUBSCRIPTION RIGHTS

We may issue subscription rights to purchase our Ordinary Shares and/or ADSs. These subscription rights may be issued independently or together with any other security offered hereby and may or may not be transferable by the shareholder receiving the subscription rights in such offering. In connection with any offering of subscription rights, we may enter into a standby arrangement with one or more underwriters or other purchasers pursuant to which the underwriters or other purchasers may be required to purchase any securities remaining unsubscribed for after such offering.

We urge you to read the applicable subscription right agreement and any applicable prospectus supplement in their entirety.

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:

PLAN OF DISTRIBUTION

The securities being offered by this prospectus may be sold:

• through agents;

• to or through one or more underwriters on a firm commitment or agency basis;

• through put or call option transactions relating to the securities;

• in at the market offerings into an existing trading market in accordance with Rule 415(a)(4) of the Securities Act;

• through broker-dealers;

• directly to purchasers, through a specific bidding or auction process, on a negotiated basis or otherwise;

• through any other method permitted pursuant to applicable law; or

• through a combination of any such methods of sale.

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 reallowed 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.

The distribution of securities may be effected from time to time in one or more transactions, including block transactions and transactions on the Nasdaq Global 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.

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.

14

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.

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 ( 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.

15

In addition, Ordinary Shares or ADSs may be issued upon conversion of or in exchange for debt securities or other securities.

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 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 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 or ADSs sold will be sold at prices related to the then prevailing market prices for our Ordinary 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, 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, if not identified in this prospectus, 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 or in connection with a simultaneous offering of other securities offered by this prospectus.

LEGAL MATTERS

Certain legal matters with respect to Israeli law and with respect to the validity of the offered securities under Israeli law will be passed upon for us by Gross & Co. Certain legal matters with respect to U.S. federal securities law and New York law will be passed upon for us by Haynes and Boone, LLP.

EXPERTS

WHERE YOU CAN FIND MORE INFORMATION

We have filed with the SEC a registration statement on Form F-3 under the Securities Act, with respect to the securities offered by this prospectus. However, as is permitted by the rules and regulations of the SEC, this prospectus, which is part of our registration statement on Form F-3, omits certain non-material information, exhibits, schedules and undertakings set forth in the registration statement. For further information about us, and the securities offered by this prospectus, please refer to the registration statement.

We are subject to the reporting requirements of the Exchange Act that are applicable to a foreign private issuer.

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 the procedure will also be governed by Israeli law.

Subject to specified 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 judgments are obtained after due process before a court of competent jurisdiction, according to the laws of the state in which the judgment is given and the rules of private international law currently prevailing in Israel;

• the prevailing law of the foreign state in which the judgments were rendered allows the enforcement of judgments of Israeli courts (however, the Israeli courts may waive this requirement following a request by the attorney general);

• adequate service of process has been effected and the defendant has had a reasonable opportunity to be heard and to present his or her evidence;

• the judgments are not contrary to public policy, and the enforcement of the civil liabilities set forth in the judgment does not impair the security or sovereignty of the State of Israel;

• the judgments were not obtained by fraud and do not conflict with any other valid judgment 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; and

• the obligations under the judgment are enforceable according to the laws of the State of Israel and according to the law of the foreign state in which the relief was granted.

18

We have irrevocably appointed RedHill Biopharma Inc. 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.
