PROSPECTUS SUMMARY

This summary highlights certain information about us, this offering and selected information contained elsewhere in or incorporated by reference into this prospectus. This summary is not complete and does not contain all of the information that you should consider before deciding whether to invest in our ordinary shares. For a more complete understanding of our Company and this offering, we encourage you to read and consider carefully the more detailed information in this prospectus, including the information incorporated by reference in this prospectus, and the information included in any free writing prospectus that we have authorized for use in connection with this offering, including the information under the heading “Risk Factors” in this prospectus on pageS-3 and in the documents incorporated by reference into this prospectus.

Company Overview

We are a clinical stage biopharmaceutical company focused on developing novel therapies designed to change the standard of care for urological pathologies. We have an innovative and broad pipeline of product candidates that we believe can overcome the deficiencies of current treatment options for a variety of urological conditions with a focus onuro-oncology. Our lead product candidates,UGN-101 andUGN-102, are proprietary formulations of the chemotherapy drug Mitomycin C, a generic drug, which is currently usedoff-label for urothelial cancer treatment only in a water-based formulation as an adjuvant, or supplemental post-surgery, therapy. We are developing our product candidates as chemoablation agents, which means they are designed to remove tumors bynon-surgical means, to treat several forms ofnon-muscle invasive urothelial cancer, includinglow-grade upper tract urothelial carcinoma andlow-grade bladder cancer. We believe thatUGN-101 andUGN-102, which are both local drug therapies, have the potential to significantly improve patients’ quality of life by replacing costly,sub-optimal and burdensome tumor resection and kidney removal surgeries as the first-line standard of care.UGN-101 andUGN-102 may also reduce the need for bladder and upper urinary tract surgeries, including removal of the upper urinary tract, which are major surgical procedures typically performed when local endoscopic tumor resection fails to control the disease progression. Additionally, we believe that our product candidates, which are based on novel formulations of previously approved drugs, may qualify for streamlined regulatory pathways to market approval.

RISK FACTORS

Investing in our securities involves a high degree of risk. You should carefully review the risks and uncertainties described below and under the section titled “Risk Factors” in our most recent Annual Report on Form10-K and in our most recent Quarterly Report on Form10-Q, as updated by our subsequent filings, which are incorporated by reference into this prospectus, before deciding whether to purchase any of the securities being registered pursuant to the registration statement of which this prospectus is a part. Each of the risk factors could adversely affect our business, results of operations, financial condition and cash flows, as well as adversely affect the value of an investment in our securities, and the occurrence of any of these risks might cause you to lose all or part of your investment. Additional risks not presently known to us or that we currently believe are immaterial may also significantly impair our business operations. Please also read carefully the section below titled “Special Note Regarding Forward-Looking Statements.”

Additional Risks Related to This Offering

You may experience dilution.

The offering price per share in this offering may exceed the net tangible book value per share of our ordinary shares outstanding prior to this offering. Assuming that an aggregate of 2,956,830 ordinary shares are sold at a price of $33.82 per share, the last reported sale price of our ordinary shares on Nasdaq on December 18, 2019, for aggregate gross proceeds of approximately $100.0 million, and after deducting commissions and estimated offering expenses payable by us, you would experience immediate dilution of $20.95 per share, representing the difference between our as adjusted net tangible book value per share as of September 30, 2019 after giving effect to this offering and the assumed offering price. See the section titled “Dilution” below for a more detailed illustration of the dilution you would incur if you participate in this offering. Because the sales of the shares offered hereby will be made directly into the market or in negotiated transactions, the prices at which we sell these shares will vary and these variations may be significant. Purchasers of the shares we sell, as well as our existing shareholders, will experience significant dilution if we sell shares at prices significantly below the price at which they invested. In addition, to the extent we need to raise additional capital in the future and we issue additional ordinary shares or securities convertible or exchangeable for our ordinary shares, our then existing shareholders may experience dilution and the new securities may have rights senior to those of our ordinary shares offered in this offering.

Our management might apply the net proceeds from this offering in ways with which you do not agree and in ways that may impair the value of your investment.

We currently intend to use the net proceeds from this offering for working capital and general corporate purposes, which may include costs associated with the commercialization ofUGN-101, if approved, or any other approved product, continued clinical development ofUGN-102, research and development for other pipeline programs, in addition to other capital expenditures, and general and administrative expenses. We may also use a portion of the net proceeds toin-license, invest in or acquire businesses, assets or technologies that we believe are complementary to our own, although we have no current plans, commitments or agreements with respect to any acquisitions. As of the date of this prospectus, we cannot specify with certainty all of the particular uses of the net proceeds from this offering. Pending the use of net proceeds, we intend to invest the net proceeds in investment-grade, interest bearing instruments. Our management has broad discretion as to the use of these proceeds and you will be relying on the judgment of our management regarding the application of these proceeds. We might apply these proceeds in ways with which you do not agree, or in ways that do not yield a favorable return. If our management applies these proceeds in a manner that does not yield a significant return, if any, on our investment of these net proceeds, it could compromise our ability to pursue our growth strategy and adversely affect the market price of our ordinary shares.

The actual number of shares we will issue under the sales agreement, at any one time or in total, is uncertain.

Subject to certain limitations in the sales agreement and compliance with applicable law, we have the discretion to deliver a placement notice to Cowen and Company, LLC, or Cowen, at any time throughout the term of the sales agreement. The number of shares that are sold by Cowen after delivering a placement notice will fluctuate based on the market price of the ordinary shares during the sales period and limits we set with Cowen. Because the price per ordinary share sold will fluctuate based on the market price of our ordinary shares during the sales period, it is not possible at this stage to predict the number of ordinary shares that will be ultimately issued.

Any statements in this prospectus, or incorporated herein by reference, about our expectations, beliefs, plans, objectives, assumptions or future events or performance are not historical facts and are forward-looking statements.

These statements reflect our views as of the date on which they were made with respect to future events and are based on assumptions and subject to risks and uncertainties. The underlying information and expectations are likely to change over time. In addition, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based upon information available to us as of the date the statement is made, and while we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain and you are cautioned not to unduly rely upon these statements.

Given these uncertainties, you should not place undue reliance on these forward-looking statements as actual events or results may differ materially from those projected in the forward-looking statements due to various factors, including, but not limited to, those set forth under the heading “Risk Factors” in any applicable prospectus supplement, the documents incorporated by reference therein or any free writing prospectus that we authorized. These forward-looking statements represent our estimates and assumptions only as of the date of the document containing the applicable statement. Our actual future results may be materially different from what we expect. We qualify all of the forward-looking statements contained in this prospectus, in the documents incorporated by reference herein and in any prospectus supplement by these cautionary statements. Unless required by law, we undertake no obligation to update or revise any forward-looking statements to reflect new information or future events or developments. Thus, you should not assume that our silence over time means that actual events are bearing out as expressed or implied in such forward-looking statements. Before deciding to purchase our securities, you should carefully consider the risk factors discussed herein or incorporated by reference, in addition to the other information set forth in this prospectus, any accompanying prospectus supplement or free writing prospectus and in the documents incorporated by reference.

S-5

USE OF PROCEEDS

We may issue and sell ordinary shares having aggregate sales proceeds of up to $100.0 million from time to time. Because there is no minimum offering amount required as a condition to close this offering, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time. There can be no assurance that we will sell any shares under or fully utilize the sales agreement with Cowen as a source of financing.

We currently intend to use the net proceeds from this offering for working capital and general corporate purposes, which may include costs associated with the commercialization ofUGN-101, if approved, or any other approved product, continued clinical development ofUGN-102, research and development for other pipeline programs, in addition to other capital expenditures and general and administrative expenses. We may also use a portion of the net proceeds toin-license, invest in or acquire businesses, assets or technologies that we believe are complementary to our own, although we have no current plans, commitments or agreements with respect to any acquisitions. As of the date of this prospectus, we cannot specify with certainty all of the particular uses of the net proceeds from this offering. Accordingly, we will retain broad discretion over the use of such proceeds. Pending the use of the net proceeds from this offering, we intend to invest the net proceeds in investment-grade, interest-bearing instruments.

S-6

DILUTION

Our net tangible book value as of September 30, 2019 was $210.9 million, or $10.07 per share. Net tangible book value per share is determined by dividing our total tangible assets, less total liabilities, by the number of ordinary shares outstanding as of September 30, 2019. Dilution with respect to net tangible book value per share represents the difference between the amount per share paid by purchasers of ordinary shares in this offering and the net tangible book value per share of our ordinary shares immediately after this offering.

After giving effect to the sale of 2,956,830 ordinary shares in this offering at an assumed offering price of $33.82 per share, the last reported sale price of our ordinary shares on Nasdaq on December 18, 2019, and after deducting estimated offering commissions and offering expenses payable by us, our as adjusted net tangible book value as of September 30, 2019 would have been $307.7 million, or $12.87 per share. This represents an immediate increase in net tangible book value of $2.80 per share to existing shareholders and immediate dilution of $20.95 per share to investors purchasing our ordinary shares in this offering at the public offering price. The following table illustrates this dilution on a per share basis:

Assumed public offering price per share			$	33.82
Net tangible book value per share of as September 30, 2019	$	10.07
Increase in net tangible book value per share attributable to this offering	$	2.80
As adjusted net tangible book value per share as of September 30, 2019, after giving effect to this offering			$	12.87
Dilution per share to investors purchasing our ordinary shares in this offering			$	20.95

The above discussion and table are based on 20,944,250 ordinary shares outstanding as of September 30, 2019, and exclude, as of such date:

• 2,975,637 of our ordinary shares issuable upon the exercise of outstanding stock options, at a weighted-average exercise price of $32.43 per share;

• 510,555 ordinary shares reserved for issuance upon the vesting of outstanding restricted stock units;

• 602,733 of our ordinary shares reserved for future issuance under our 2017 Equity Incentive Plan;

• 821,600 of our ordinary shares reserved for future issuance under our 2019 Inducement Plan; and

• 278,400 ordinary shares reserved for issuance upon the achievement of certain milestones under theUGN-201 asset purchase agreement with Telormedix SA.

The table above assumes for illustrative purposes that an aggregate of 2,956,830 ordinary shares are sold during the term of the sales agreement with Cowen at a price of $33.82 per share, the last reported sale price of our ordinary shares on Nasdaq on December 18, 2019, for aggregate gross proceeds of approximately $100.0 million. The shares subject to the sales agreement with Cowen are being sold from time to time at various prices. An increase of $1.00 per share in the price at which the shares are sold from the assumed offering price of $33.82 per share shown in the table above, assuming all of our ordinary shares in the aggregate amount of approximately $100.0 million during the term of the sales agreement with Cowen is sold at that price, would result in adjusted net tangible book value per share after the offering of $12.92 per share and would increase the dilution in net tangible book value per share to new investors in this offering to $21.90 per share, after deducting commissions and estimated aggregate offering expenses payable by us. A decrease of $1.00 per share in the price at which the shares are sold from the assumed offering price of $33.82 per share shown in the table above, assuming all of our ordinary shares in the aggregate amount of approximately $100.0 million during the term of the sales agreement with Cowen is sold at that price, would result in adjusted net tangible book value per share after the offering of $12.83 per share and would decrease the dilution in net tangible book value per share to new investors in this offering to $19.99 per share, after deducting commissions and estimated aggregate offering expenses payable by us. This information is supplied for illustrative purposes only and assumes no exercise of the options outstanding as of September 30, 2019.

To the extent that options outstanding as of September 30, 2019 have been or may be exercised or other shares issued, investors purchasing our ordinary shares in this offering may experience further dilution. In addition, we may choose to raise additional capital due to market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our shareholders.

S-7

PLAN OF DISTRIBUTION

We have entered into a sales agreement with Cowen, under which we may issue and sell from time to time up to $100,000,000 of our ordinary shares through Cowen as our sales agent. Sales of our ordinary shares, if any, will be made at market prices by any method that is deemed to be an “at the market offering” as defined in Rule 415(a)(4) under the Securities Act, including sales made directly on Nasdaq or any other trading market for our ordinary shares. If authorized by us in writing, Cowen may purchase shares of our ordinary shares as principal.

Cowen will offer our ordinary shares subject to the terms and conditions of the sales agreement on a daily basis or as otherwise agreed upon by us and Cowen. We will designate the maximum amount of ordinary shares to be sold through Cowen on a daily basis or otherwise determine such maximum amount together with Cowen. Subject to the terms and conditions of the sales agreement, Cowen will use its commercially reasonable efforts to sell on our behalf all of the ordinary shares requested to be sold by us. We may instruct Cowen not to sell ordinary shares if the sales cannot be effected at or above the price designated by us in any such instruction. Cowen or we may suspend the offering of our ordinary shares being made through Cowen under the sales agreement upon proper notice to the other party. Cowen and we each have the right, by giving written notice as specified in the sales agreement, to terminate the sales agreement in each party’s sole discretion at any time.

The aggregate compensation payable to Cowen as sales agent equals 3.0% of the gross sales price of the shares sold through it pursuant to the sales agreement. We have also agreed to reimburse Cowen for its actual outside legal expenses incurred by Cowen in connection with this offering, and for certain other expenses, including Cowen’s FINRA counsel fees, in an aggregate amount of up to $50,000. In accordance with FINRA Rule 5110, these reimbursed expenses are deemed sales compensation in connection with this offering. We estimate that the total expenses of the offering payable by us, excluding commissions payable to Cowen under the sales agreement, will be approximately $225,000.

The remaining sales proceeds, after deducting any expenses payable by us and any transaction fees imposed by any governmental, regulatory, or self-regulatory organization in connection with the sales, will equal our net proceeds for the sale of such ordinary shares.

Cowen will provide written confirmation to us following the close of trading on Nasdaq on each day in which ordinary shares are sold through it as sales agent under the sales agreement. Each confirmation will include the number of ordinary shares sold through it as sales agent on that day, the volume weighted average price of the shares sold, the percentage of the daily trading volume and the net proceeds to us.

We will report at least quarterly the number of ordinary shares sold through Cowen under the sales agreement, the net proceeds to us and the compensation paid by us to Cowen in connection with the sales of ordinary shares.

Settlement for sales of ordinary shares will occur, unless the parties agree otherwise or otherwise required by law, on the second business day that is also a trading day following the date on which any sales were made in return for payment of the net proceeds to us. There is no arrangement for funds to be received in an escrow, trust or similar arrangement.

In connection with the sales of our ordinary shares on our behalf, Cowen will be deemed to be an “underwriter” within the meaning of the Securities Act, and the compensation paid to Cowen will be deemed to be underwriting commissions or discounts. We have agreed in the sales agreement to provide indemnification and contribution to Cowen against certain liabilities, including liabilities under the Securities Act. As sales agent, Cowen will not engage in any transactions that stabilize our ordinary shares.

Our ordinary shares are listed on Nasdaq and trade under the symbol “URGN.” The transfer agent of our ordinary shares is Computershare Trust Company, N.A.

Cowen and/or its affiliates have provided, and may in the future provide, various investment banking and other financial services for us for which services they have received and, may in the future receive, customary fees.

TAXATION

The following description is not intended to constitute a complete analysis of all tax consequences relating to the acquisition, ownership and disposition of our ordinary shares. You should consult your own tax advisor concerning the tax consequences in your particular situation, as well as any tax consequences that may arise under the laws of any state, local, foreign or other taxing jurisdiction.

Israeli Tax Considerations and Government Programs

The following is a brief summary of the material Israeli tax laws applicable to us. This section also contains a discussion of material Israeli tax consequences concerning the ownership and disposition of our ordinary shares purchased by investors in this offering. This summary does not discuss certain tax benefits, including under the Law for Encouragement of Capital Investments, 5719-1959, to which we may become eligible in the future if we establish a manufacturing facility for our products in Israel. This summary also does not discuss all the aspects of Israeli tax law that may be relevant to a particular investor in light of his or her personal investment circumstances or to some types of investors subject to special treatment under Israeli law. Examples of such investors include residents of Israel or traders in securities who are subject to special tax regimes not covered in this discussion. Because parts of this discussion are based on new tax legislation that has not yet been subject to judicial or administrative interpretation, the appropriate tax authorities or the courts may not accept the views expressed in this discussion. The discussion below is subject to change, including due to amendments under Israeli law or changes to the applicable judicial or administrative interpretations of Israeli law, which change could affect the tax consequences described below.

General Corporate Tax Structure in Israel

As of 2018, Israeli companies are generally subject to corporate tax at the rate of 23% of a company’s taxable income (reduced from 24% in 2017). In addition, capital gains realized by Israeli companies are subject to tax at the regular corporate tax rate.

Taxation of our Shareholders

Capital gains taxes applicable tonon-Israeli resident shareholders. As of 2018, capital gain is generally subject to tax at the corporate tax rate of 23% (reduced from 24% in 2017) if generated by a company, or at the rate of 25% if generated by an individual, or 30% in the case of sale of shares by a substantial shareholder at the time of sale or at any time during the preceding12-month period. A person is considered to be a substantial shareholder if it holds, directly or indirectly, alone or together with another affiliated party, 10% or more of a company’s means of control, which include, among other things, voting rights, the right to receive profits of the company, the right to receive proceeds upon liquidation and the right to appoint a director.

Notwithstanding the foregoing, anon-Israeli resident who derives capital gains from the sale of our shares that were purchased after the shares were listed for trading on the NASDAQ is exempt from Israeli tax on such capital gains so long as they were not attributable to a permanent establishment that thenon-resident maintains in Israel. In the case of a shareholder that is a corporation, in order for it to qualify as anon-Israeli resident for these purposes, it must be incorporated in, as well as managed and controlled from, a jurisdiction other than the State of Israel, and persons who are Israeli residents may not either: (i) have a controlling interest (directly or indirectly, alone or together with another, or together with another Israeli resident) exceeding 25% in one or more of the means of control in such corporation or (ii) be the beneficiaries of, or entitled to, 25% or more of the revenues or profits of such corporation, whether directly or indirectly. Such exemption is not applicable to a person whose gains from selling or otherwise disposing of the shares are deemed to be business income.

Additionally, a sale of shares by anon-Israeli resident may be exempt from Israeli capital gains tax under the provisions of an applicable tax treaty.

Shareholders may be required to demonstrate that they are exempt from tax on their capital gains in order to avoid withholding at source at the time of sale. In transactions involving a sale of all of the shares of an Israeli resident company, such as a merger or other transaction, the Israel Tax Authority may, among other things, require from shareholders who are not liable for Israeli tax the execution of a declaration in the form specified by that authority or a specific exemption from the Israeli Tax Authority to confirm their status asnon-Israeli residents may be required to be presented, and, in the absence of such declaration or exemption, may require the purchaser of the shares to withhold taxes.

S-9

In addition, with respect to mergers involving an exchange of shares, Israeli tax law allows for tax deferral in certain circumstances, but makes the deferral contingent on the fulfillment of a number of conditions, including, in some cases, a holding period of two years from the date of the transaction during which sales and dispositions of shares of the participating companies are subject to certain restrictions. Moreover, with respect to certain share swap transactions in which the sellers receive shares in the acquiring entity that are publicly traded on a stock exchange, the tax deferral is limited in time, and when such time expires, the tax becomes payable even if no disposition of such shares has occurred.

Taxation ofnon-Israeli shareholders on receipt of dividends.Non-Israeli residents are generally subject to Israeli withholding tax on the receipt of dividends paid on our ordinary shares at the rate of 25%, unless relief is provided in a treaty between Israel and the shareholder’s country of residence (subject to the receipt of a valid certificate from the Israel Tax Authority, allowing for such reduced withholding tax rate). With respect to a person who is considered a substantial shareholder at the time of receiving the dividend or at any time during the preceding 12 months, subject to the terms of an applicable tax treaty, the applicable withholding tax rate is 30%.

Under 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 Tax Treaty, the maximum rate of tax withheld at source in Israel on dividends paid to a holder of our ordinary shares who is a U.S. resident (for the purposes of the U.S.-Israel Tax Treaty) is 25%. However, with regard to dividends paid to a U.S. resident corporation which held 10% or more of our outstanding voting rights throughout the taxable year in which the dividend was distributed and which maintained its shareholdings at or above such threshold during the entire previous taxable year, the maximum rate of withholding tax is generally 12.5%, provided that no more than 25% of our gross income for such preceding year consists of certain types of dividends and interest.

U.S. residents who are subject to Israeli withholding tax on a dividend may be entitled to a credit or deduction for U.S. federal income tax purposes in the amount of the taxes withheld, subject to detailed limitations under U.S. laws applicable to foreign tax credits.

Excess Tax. Individuals who are subject to tax in Israel, whether an Israeli resident or anon-Israeli resident, are also subject to an additional tax on annual income exceeding NIS 640,000 in 2017 and thereafter (linked to the Israeli consumer price index) at a rate of 3%, including, but not limited to, dividends, interest and capital gain, subject to the provisions of an applicable tax treaty.

Material U.S. Federal Income Tax Consequences to U.S. Holders

The following discussion describes the material U.S. federal income tax consequences to U.S. Holders (as defined below) under present law of an investment in our ordinary shares sold pursuant to this offering. The effects of any applicable state or local laws, or other U.S. federal tax laws such as estate and gift tax laws are not discussed. This summary applies only to investors who hold the ordinary shares as capital assets (generally, property held for investment) and who have the U.S. dollar as their functional currency. This discussion is based on the Internal Revenue Code of 1986, as amended, or the Code, U.S. Treasury regulations promulgated thereunder, judicial decisions, published rulings and administrative pronouncements of the U.S. Internal Revenue Service, or the IRS, and the U.S.-Israel Tax Treaty, all as in effect as of the date of this offering. All of the foregoing authorities are subject to change, which change could apply retroactively and could affect the tax consequences described below.

The following discussion does not address all U.S. federal income tax consequences relevant to a holder’s particular circumstances or to holders subject to particular rules, including:

• U.S. expatriates and certain former citizens or long-term residents of the United States;

• persons subject to the alternative minimum tax;

• persons holding our ordinary shares as part of a hedge, straddle or other risk reduction strategy or as part of a conversion transaction or other integrated investment for U.S. federal income tax purposes;

• banks, insurance companies, and other financial institutions;

• real estate investment trusts and regulated investment companies;

• brokers, dealers, and traders in securities, commodities or currencies;

• partnerships, S corporations, and other entities or arrangements treated as partnerships for U.S. federal income tax purposes;

S-10

• tax-exempt organizations and governmental organizations;

• persons that own, directly, indirectly or constructively 10% or more of our stock;

• persons that hold their shares through a permanent establishment or fixed base outside the United States; and

• persons deemed to sell our ordinary shares under the constructive sale provisions of the Code.

U.S. HOLDERS ARE URGED TO CONSULT THEIR TAX ADVISORS REGARDING THE APPLICATION OF THE U.S. FEDERAL TAX RULES TO THEIR PARTICULAR CIRCUMSTANCES AS WELL AS THE U.S. STATE AND LOCAL ANDNON-U.S. TAX CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE ORDINARY SHARES.

For purposes of this discussion, a “U.S. Holder” is a beneficial owner of our ordinary shares that, for U.S. federal income tax purposes, is or is treated as any of the following:

• an individual who is a citizen or resident of the United States;

• a corporation, or entity treated as a corporation for U.S. federal income tax purposes, created or organized under the laws of the United States, 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 that (1) is subject to the supervision of a U.S. court and the control of one or more “United States persons” (within the meaning of Section 7701(a)(30) of the Code), or (2) has a valid election in effect to be treated as a United States person for U.S. federal income tax purposes.

If you are a partner in a partnership (or other entity taxable as a partnership for U.S. federal income tax purposes) that holds our ordinary shares, your tax treatment generally will depend on your status and the activities of the partnership. Partnerships holding our ordinary shares and the partners in such partnerships should consult their tax advisors regarding the U.S. federal income tax consequences applicable to them.

As indicated below, this entire discussion is subject to the discussion of the U.S. federal income tax rules applicable to a “passive foreign investment company,” or a PFIC.

Passive Foreign Investment Company Considerations

If we are classified as a PFIC in any taxable year, a U.S. Holder will be subject to special rules generally intended to reduce or eliminate any benefits from the deferral of U.S. federal income tax that a U.S. Holder could derive from investing in anon-U.S. company that does not distribute all of its earnings on a current basis.

We must determine our PFIC status annually based on tests (described below) which are factual in nature, and our status will depend on our income, assets and activities each year. In addition, our status as a PFIC may depend on how quickly we use the cash proceeds from this offering in our business. We believe that we were classified as a PFIC for the taxable year ended December 31, 2018, and based upon the expected nature and composition of our income and assets, we anticipate that we will be classified as a PFIC for the taxable year ending December 31, 2019. We cannot provide any assurances regarding our PFIC status for the current or future taxable years, and our U.S. tax counsel has not provided any opinion regarding our PFIC status.

Anon-U.S. corporation is classified as a PFIC for U.S. federal income tax purposes in any taxable year in which, after applying certain look-through rules with respect to the income and assets of subsidiaries, either (i) at least 75% of its gross income is “passive income” or (ii) at least 50% of the average quarterly value of its total gross assets (which, assuming we are not a CFC for the year being tested, would be measured by fair market value of the assets, and for which purpose the total value of our assets may be determined in part by the market value of our ordinary shares, which is subject to change) is attributable to assets that produce “passive income” or are held for the production of passive income.

Passive income for this purpose generally includes dividends, interest, royalties, rents, gains from commodities and securities

S-11

transactions, the excess of gains over losses from the disposition of assets which produce passive income, and generally includes amounts derived by reason of the temporary investment of funds raised in offerings of our ordinary shares. However, rents and royalties received from unrelated parties in connection with the active conduct of a trade or business are not considered passive income for purposes of the PFIC test. If anon-U.S. corporation owns directly or indirectly at least 25% by value of the stock of another corporation, thenon-U.S. corporation is treated for purposes of the PFIC tests as owning its proportionate share of the assets of the other corporation and as receiving directly its proportionate share of the other corporation’s income. If we are classified as a PFIC in any year with respect to which a U.S. Holder owns our ordinary shares, we will continue to be treated as a PFIC with respect to such U.S. Holder in all succeeding years during which the U.S. Holder owns our ordinary shares, regardless of whether we continue to meet the tests described above unless the holder makes one of the PFIC elections described below with respect to our ordinary shares.

U.S. Holders should consult with their tax advisors regarding the availability and consequences of any PFIC elections.

If we are a PFIC, and you are a U.S. Holder, then unless you make one of the elections described below, a special tax regime will apply to both (a) any “excess distribution” by us to you (generally, your ratable portion of aggregate distributions in any year which are greater than 125% of the average annual distribution received by you in the shorter of the three preceding years or your holding period for our ordinary shares) and (b) any gain realized on the sale or other disposition of the ordinary shares. Under this regime, any excess distribution and realized gain will be treated as ordinary income and will be subject to tax as if (a) the excess distribution or gain had been realized ratably over your holding period, (b) the amount deemed realized in each year had been subject to tax in each year of that holding period at the highest marginal rate for such year (other than income allocated to the current period or any taxable period before we became a PFIC, which would be subject to tax at the U.S. Holder’s regular ordinary income rate for the current year and would not be subject to the interest charge discussed below), and (c) the interest charge generally applicable to underpayments of tax had been imposed on the taxes deemed to have been payable in those years. In addition, dividend distributions made to you will not qualify for the lower rates of taxation applicable to long-term capital gains discussed under “Taxation of Dividends and Other Distributions on Our Ordinary Shares.”

Certain elections exist that may alleviate some of the adverse consequences of PFIC status and would result in an alternative treatment of our ordinary shares. If a U.S. Holder makes amark-to-market election, then in lieu of being subject to the tax and interest charge rules disclosed above, the U.S. Holder generally will recognize as ordinary income any excess of the fair market value of the ordinary shares at the end of each taxable year over their adjusted tax basis, and will recognize an ordinary loss in respect of any excess of the adjusted tax basis of the ordinary shares over their fair market value at the end of the taxable year (but only to the extent of the net amount of income previously included as a result of themark-to-market election). If a U.S. Holder makes the election, the U.S. Holder’s tax basis in the ordinary shares will be adjusted to reflect these income or loss amounts. Any gain recognized on the sale or other disposition of ordinary shares in a year when we are a PFIC will be treated as ordinary income and any loss will be treated as an ordinary loss (but only to the extent of the net amount of income previously included as a result of themark-to-market election). Themark-to-market election is available only if we are a PFIC and our ordinary shares are “regularly traded” on a “qualified exchange.” Our ordinary shares will be treated as “regularly traded” in any calendar year in which more than ade minimis quantity of the ordinary shares are traded on a qualified exchange on at least 15 days during each calendar quarter (subject to the rule that trades that have as one of their principal purposes the meeting of the trading requirement are disregarded). The NASDAQ Global Market is a qualified exchange for this purpose and, consequently, if the ordinary shares are regularly traded, themark-to-market election will be available to a U.S. Holder.

If we are determined to be a PFIC (and if a QEF Election discussed below is not made), the general tax treatment for U.S. Holders described in this section will apply to indirect distributions and gains deemed to be realized by U.S. Holders in respect of any of our subsidiaries that also may be determined to be PFICs. Amark-to-market election cannot be made with respect to the stock of any of our subsidiaries.

If we are a PFIC, we expect to provide investors, by annually posting a “PFIC Annual Information Statement” on our website, with the information required to allow investors to make a qualified electing fund election, or a “QEF Election,” for United States federal income tax purposes. A U.S. Holder can make a QEF Election, if we provide the necessary information, to treat us and each lower-tier PFIC as a qualified electing fund in the first taxable year we (and our relevant subsidiaries) are treated as a PFIC with respect to the U.S. Holder. If such election is made or remains in place while we and any lower-tier PFIC subsidiaries are PFICs, we and our subsidiaries will not be treated as PFICs with respect to such U.S. Holder. In order to make a QEF Election for us and for each of our subsidiaries that is a PFIC, a U.S. Holder must attach a separate properly completed IRS Form 8621 for each such PFIC to the U.S. Holder’s timely filed U.S. federal income tax return.

S-12

If a U.S. Holder makes a QEF Election with respect to a PFIC, in lieu of the tax consequences described above, the U.S. Holder will be subject to current taxation on its pro rata share of the PFIC’s ordinary earnings and net capital gain (at ordinary income and capital gain rates, respectively) for each taxable year that the entity is classified as a PFIC. If a U.S. Holder makes a QEF Election with respect to us, any distributions paid by us out of our earnings and profits that were previously included in the U.S. Holder’s income under the QEF Election would not be taxable to the holder. A U.S. Holder will increase its tax basis in its ordinary shares by an amount equal to any income included under the QEF Election and will decrease its tax basis by any amount distributed on the ordinary shares that is not included in the holder’s income. In addition, a U.S. Holder will recognize capital gain or loss on the disposition of ordinary shares in an amount equal to the difference between the amount realized and the holder’s adjusted tax basis in the ordinary shares. U.S. Holders should note that if they make QEF Elections with respect to us and lower-tier PFICs, they may be required to pay U.S. federal income tax with respect to their ordinary shares for any taxable year significantly in excess of any cash distributions (which are expected to be zero) received on the ordinary shares for such taxable year. U.S. Holders should consult their tax advisors regarding making QEF Elections in their particular circumstances. If a U.S. Holder does not make and maintain a QEF election for the U.S. Holder’s entire holding period for our ordinary shares by making the election for the first year in which the U.S. Holder owns our ordinary shares pursuant to this offering, the U.S. Holder will be subject to the adverse PFIC rules discussed above unless the U.S. Holder can properly make a “purging election” with respect to our ordinary shares in connection with the U.S. Holder’s QEF Election. A purging election may require the U.S. Holder to recognize taxable gain on the U.S. Holder’s shares. No purging election is necessary for a U.S. Holder that timely makes a QEF election for the first year in which the U.S. Holder acquired our ordinary shares. If a U.S. Holder does not make and maintain a QEF election for the U.S. Holder’s entire holding period for our ordinary shares by making the election for the first year in which the U.S. Holder owns our ordinary shares pursuant to this offering, the U.S. Holder will be subject to the adverse PFIC rules discussed above unless the U.S. Holder can properly make a “purging election” with respect to our ordinary shares in connection with the U.S. Holder’s QEF Election. A purging election may require the U.S. Holder to recognize taxable gain on the U.S. Holder’s shares. No purging election is necessary for a U.S. Holder that timely makes a QEF election for the first year in which the U.S. Holder acquired our ordinary shares.

Each U.S. Holder that is an investor of a PFIC is generally required to file an annual information return on IRS Form 8621 (Information Return by a Shareholder of a Passive Foreign Investment Company or Qualified Electing Fund) containing such information as the U.S. Treasury Department may require. The failure to file IRS Form 8621 could result in the imposition of penalties and the extension of the statute of limitations with respect to U.S. federal income tax. U.S. Holders should consult their tax advisors regarding whether we are a PFIC and the potential application of the PFIC rules.

Taxation of Dividends and Other Distributions on Our Ordinary Shares

Subject to the discussion under “—Passive Foreign Investment Company Considerations,” above, the gross amount of any distribution to you with respect to our ordinary shares will be included in your gross income as dividend income when actually or constructively received to the extent that the distribution is paid out of our current or accumulated earnings and profits (as determined under U.S. federal income tax principles). To the extent the amount of the distribution exceeds our current and accumulated earnings and profits, it will be treated first as a return of your tax basis in our ordinary shares, and to the extent the amount of the distribution exceeds your tax basis, the excess will be taxed as capital gain. While we currently calculate our earnings and profits under U.S. federal income tax principles, we cannot give any assurances that we will continue to do so in the future. If we do not calculate our earnings and profits under U.S. federal income tax purposes, a U.S. Holder should expect that the entire amount of any distribution will generally be reported as dividend income. Any dividends will not be eligible for the dividends-received deduction allowed to corporations in respect of dividends received from other U.S. corporations.

If we are not a PFIC for a given year in which a dividend is paid and the taxable year preceding the dividend,non-corporate U.S. Holders may qualify for the preferential rates of taxation with respect to dividends on ordinary shares applicable to long-term capital gains (i.e., gains from the sale of capital assets held for more than one year) applicable to qualified dividend income (as discussed below). We believe that we qualify as a resident of Israel for purposes of, and are eligible for the benefits of, the U.S.-Israel Tax Treaty, although there can be no assurance in this regard. Further, the IRS has determined that the U.S.-Israel Tax Treaty is satisfactory for purposes of the qualified dividend rules and that it includes anexchange-of-information program. Therefore, subject to the discussion under “—Passive Foreign Investment Company Considerations” above, if the U.S.-Israel Tax Treaty is applicable, such dividends will generally be “qualified dividend income” in the hands of individual U.S. Holders, provided that certain conditions are met, including holding period and the absence of certain risk reduction transaction requirements. The dividends will not be eligible for the dividends received deduction generally allowed to corporate U.S. Holders. As discussed in “Taxation—Israeli Tax Considerations and Government Programs,” payments of dividends by us may be subject to Israeli withholding tax. For U.S. federal income tax purposes, U.S. Holders will be treated as having received the amount of Israeli taxes withheld by us, and as then having paid over the withheld taxes to the Israeli taxing authorities. As a result of this rule, the amount of dividend income included in gross income for U.S. federal income tax purposes by a U.S. Holder with respect to a payment of dividends may be greater than the amount of cash actually received (or receivable) by the U.S. Holder from us with respect to the payment. Dividends will generally constitute foreign-source income for foreign tax credit limitation purposes. Any tax withheld with respect to distributions on our ordinary shares at the rate applicable to a U.S. Holder may, subject to a number of complex limitations, be claimed as a foreign tax credit against such U.S. Holder’s U.S.

S-13

federal income tax liability or may be claimed as a deduction for U.S. federal income tax purposes. The limitation on foreign taxes eligible for credit is calculated separately with respect to specific classes of income. For this purpose, dividends distributed by us with respect to our ordinary shares generally will constitute “passive category income” or “general category income.” The rules with respect to the foreign tax credit are complex and involve the application of rules that depend upon a U.S. Holder’s particular circumstances. You are urged to consult your tax advisor regarding the availability of the foreign tax credit under your particular circumstances.

Taxation of Disposition of the Ordinary Shares

Subject to the discussion above under “—Passive Foreign Investment Company Considerations,” you will recognize gain or loss on any sale, exchange or other taxable disposition of an ordinary share equal to the difference between the amount realized on the disposition of the ordinary share and your adjusted tax basis in the ordinary share. The tax basis in an ordinary share generally will be the cost of such ordinary share. Any such gain or loss will be capital gain or loss, and will be long-term capital gain or loss if you have held the ordinary share for more than one year at the time of sale, exchange or other taxable disposition. Otherwise, such gain or loss will be short-term capital gain or loss. Long-term capital gains recognized by certainnon-corporate U.S. Holders, including individuals, generally will be taxable at a reduced rate. The deductibility of capital losses is subject to limitations. Any such gain or loss you recognize generally will be treated as U.S.-source income or loss for foreign tax credit limitation purposes.

Additional Medicare Tax

Certain U.S. Holders that are individuals, estates or trusts are subject to a 3.8% tax on all or a portion of their “net investment income,” which may include all or a portion of their dividend income and net gains from the disposition of ordinary shares. Each U.S. Holder that is an individual, estate or trust is urged to consult its tax advisors regarding the applicability of the Medicare tax to its income and gains in respect of its investment in our ordinary shares.

Information Reporting and Backup Withholding

U.S. backup withholding tax and information reporting requirements may apply to certain payments to certain holders of our ordinary shares. Information reporting will generally apply to payments of dividends on, and to proceeds from the sale or redemption of, our ordinary shares made within the United States, or by a U.S. payer or U.S. middleman, to a holder of our shares, other than an exempt recipient (including a payee that is not a U.S. person that provides an appropriate certification and certain other persons). Certain U.S. Holders are exempt from backup withholding, including corporations and certaintax-exempt organizations. A U.S. Holder will be subject to backup withholding if such holder is not otherwise exempt and such holder:

• fails to furnish the holder’s taxpayer identification number, which for an individual is ordinarily his or her social security number;

• furnishes an incorrect taxpayer identification number;

• is notified by the IRS that the holder previously failed to properly report payments of interest or dividends; or

• fails to certify under penalties of perjury that the holder has furnished a correct taxpayer identification number and that the IRS has not notified the holder that the holder is subject to backup withholding.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against the U.S. Holder’s U.S. federal income tax liability, provided the required information is timely furnished to the IRS. U.S. Holders should consult their tax advisors regarding their qualification for an exemption from backup withholding and the procedures for obtaining such an exemption.

Additional Reporting Requirements

Certain U.S. Holders who are individuals (and under proposed regulations, certain entities) are required to report information relating to an interest in our ordinary shares, subject to certain exceptions (including an exception for ordinary 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 should consult their tax advisors regarding the possible implications of these tax return disclosure obligations.
