ABOUT THIS PROSPECTUS SUPPLEMENT

We provide information to you about this offering in two separate documents: (1) this prospectus supplement, which describes the specific details regarding this offering; and (2) the base prospectus, dated May 31, 2024, which provides general information, some of which may not apply to this offering. Generally, when we refer to this “prospectus,” we are referring to both documents combined. If information in this prospectus supplement is inconsistent with the base prospectus, you should rely on 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 this prospectus supplement‒the statement in the document having the later date modifies or supersedes the earlier statement, as our business, financial condition, results of operations and prospects may have changed since the earlier dates.

In making an investment decision, prospective investors must rely on their own examination of us and the terms of the offering, including the merits and risks involved. Neither we, the selling shareholder, the underwriters nor any of our or their representatives are making any representation to you regarding the legality of an investment in our Ordinary Shares by you under applicable laws. You should consult with your own advisors as to legal, tax, business, financial and related aspects of an investment in our Ordinary Shares.

Any statement made in this prospectus or in a document incorporated or deemed to be incorporated by reference into this prospectus will be deemed to be modified or superseded for purposes of this prospectus to the extent that a statement contained in this prospectus or in any other subsequently filed document that is also incorporated by reference into this prospectus modifies or supersedes that statement. Any statement so modified or superseded will not be deemed, except as so modified or superseded, to constitute a part of this prospectus. Please read “Where You Can Find Additional Information” in this prospectus supplement.

Neither we, the selling shareholder, nor the underwriter have authorized any other person to provide you with information different from that contained or incorporated by reference in this prospectus supplement, the accompanying prospectus and any free writing prospectus. We take no responsibility for, and can provide no assurance as to the reliability of, any other information that others may give you. Neither we, the selling shareholder, nor the underwriters are making an offer to sell these securities in any jurisdiction where an offer or sale would be unlawful. The information in this prospectus supplement is accurate only as of the date of this prospectus supplement, regardless of the time of delivery of this prospectus supplement or any sale of our Ordinary Shares. You should not assume that the information contained in the documents incorporated by reference in this prospectus supplement or the accompanying prospectus is accurate as of any date other than the respective dates of those documents. Our business, financial condition, results of operations and prospects may have changed since those dates.

This prospectus supplement contains forward-looking statements that are subject to a number of risks and uncertainties, many of which are beyond our control. Please read “Risk Factors” and “Cautionary Statement Regarding Forward-Looking Statements.”

References to “we,” “us” and “our” in this prospectus, unless the context otherwise requires or as otherwise expressly stated, refer to Similarweb Ltd.

S-4

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This prospectus supplement and the documents incorporated in it by reference contain estimates and forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995, that are based on management’s expectations, beliefs or intentions regarding, among other things, our product development efforts, business, financial condition, results of operations, strategies, plans and prospects. In addition, from time to time, we or our representatives have made or may make forward-looking statements, orally or in writing. In some cases, these forward-looking statements can be identified by words or phrases such as “may,” “might,” “will,” “could,” “would,” “should,” “expect,” “plan,” “anticipate,” “intend,” “seek,” “believe,” “estimate,” “predict,” “potential,” “continue,” “contemplate,” “possible” or similar words. Statements regarding our future results of operations and financial position, growth strategy and plans and objectives of management for future operations, including, among others, expansion in new and existing markets, are forward-looking statements.

Our estimates and forward-looking statements are mainly based on our current expectations and estimates of future events and trends which affect or may affect our business, operations and industry. Although we believe that these estimates and forward-looking statements are based upon reasonable assumptions, they are subject to numerous risks and uncertainties.

These forward-looking statements are subject to a number of known and unknown risks, uncertainties, other factors and assumptions, including the risks described in Item 3.D “Key Information-Risk Factors” of our Annual Report, and elsewhere in this prospectus supplement, regarding, among other things:

• our expectations regarding our revenue, expenses and other operating results;

• our ability to acquire new customers and successfully retain existing customers;

• our ability to increase usage of our solutions and upsell and cross-sell additional solutions;

• our ability to achieve or sustain profitability;

• anticipated trends, growth rates, rising interest rates, rising global inflation and current macroeconomic conditions, challenges in our business and in the markets in which we operate, and the impact of Israel's war with Hamas and other terrorist organizations and potential hostilities with Iran or Lebanon on geopolitical and macroeconomic conditions or on our company and business;

• future investments in our business, our anticipated capital expenditures and our estimates regarding our capital requirements;

• the costs and success of our sales and marketing efforts and our ability to promote our brand;

• our reliance on key personnel and our ability to identify, recruit and retain skilled personnel;

• our ability to effectively manage our growth, including continued international expansion;

• our reliance on certain third-party platforms and sources for the collection of data necessary for our solutions;

• our ability to protect our intellectual property rights and any costs associated therewith;

• our ability to identify and complete acquisitions that complement and expand our reach and platform;

• our ability to comply or remain in compliance with laws and regulations that currently apply or become applicable to our business, including in Israel, the United States, the European Union, the United Kingdom and other jurisdictions where we elect to do business;

• our ability to compete effectively with existing competitors and new market entrants; and

• the growth rates of the markets in which we compete.

You should not rely on forward-looking statements as predictions of future events. We have based the forward-looking statements contained in this prospectus supplement primarily on our current expectations and projections about future events and trends that we believe may affect our business,

S-5

financial condition and operating results. The outcome of the events described in these forward-looking statements is subject to risks, uncertainties and other factors described under the caption “Risk Factors” and certain other matters discussed in this prospectus supplement, the documents incorporated by reference in this prospectus supplement (including our Annual Report and the information included, without limitation, under the captions under Item 3.D “Key Information—Risk Factors,” Item 4. “Information on the Company,” and Item 5. “Operating and Financial Review and Prospects” therein), and other publicly available sources. Moreover, we operate in a very competitive and rapidly changing environment. New risks and uncertainties emerge from time to time, and it is not possible for us to predict all risks and uncertainties that could have an impact on the forward-looking statements contained in this prospectus supplement. The results, events and circumstances reflected in the forward-looking statements may not be achieved or occur, and actual results, events or circumstances could differ materially from those described in the forward-looking statements.

In addition, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based on information available to us as of the date of this prospectus supplement. While we believe that information provides a reasonable basis for these statements, that information may be limited or incomplete. Our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all relevant information. These statements are inherently uncertain, and investors are cautioned not to unduly rely on these statements.

The forward-looking statements made in this prospectus supplement relate only to events as of the date on which the statements are made. We undertake no obligation to update any forward-looking statements made in this prospectus supplement to reflect events or circumstances after the date of this prospectus supplement or to reflect new information or the occurrence of unanticipated events, except as required by law. We may not actually achieve the plans, intentions or expectations disclosed in our forward-looking statements, and you should not place undue reliance on our forward-looking statements. Our forward-looking statements do not reflect the potential impact of any future acquisitions, mergers, dispositions, joint ventures or investments.

S-6

PROSPECTUS SUPPLEMENT SUMMARY

This summary highlights information contained elsewhere in this prospectus supplement and the accompanying prospectus. This summary does not contain all of the information you should consider before investing in our Ordinary Shares. You should read this entire prospectus supplement and the accompanying prospectus and the documents incorporated by reference into this prospectus supplement and the accompanying prospectus, carefully, including the risks of investing in our Ordinary Shares discussed under “Risk factors” and our consolidated financial statements and the related notes thereto included in this prospectus supplement and the accompanying prospectus and the documents incorporated by reference into this prospectus supplement and the accompanying prospectus, before making an investment decision.

Company Overview

Similarweb is a leader in digital data and analytics powering critical business decisions. We uncover what is happening online and seek to provide businesses with the best digital data and analytics to build strategy, optimize customer acquisition and enhance monetization.

While we are well known for our productized software solutions, as well as for our application programming interface (“API”) and our freemium offerings estimating website and app traffic, at our core we are a data business. Similarweb Digital Data is both our core product and our fundamental unit of value. To create our proprietary data asset, we collect billions of unprocessed web and mobile data points on activity related to companies and products. Our data scientists and engineers transform the unrefined data on interactions and transactions into the corpus of Similarweb Digital Data using machine learning and artificial intelligence. Our customers use Similarweb Digital Data to power critical decision for running their businesses through one or more of our productized solutions to which they subscribe. Today, businesses have access to unprecedented amounts of internal data that they can utilize for decision making. However, the data generally available to them only relates to the transactions and interactions with their own audience across their digital properties, such as the websites, apps and social media channels that they own. Businesses have very limited visibility into the broader behaviors of consumers, or the digital performance of competitors, partners and other players. As a result, companies operate frequently with a lack of external visibility, impairing their ability to execute on everything from corporate strategy to day-to-day operations. Similarweb provides this visibility. We believe we are becoming recognized as the standard for powering decisions that rely on data for businesses and their competitors across all channels within the digital world. Like wattage powers cities, Similarweb Digital Data powers decisions related to the digital world that create significant competitive advantages.

We deliver Similarweb Digital Data to our paying customers in a variety of modes that, combined, comprise our delivery platform: Software-as-a-Service (“SaaS”), Data-as-a-Service (“DaaS”), and Advisory Services. We organize our SaaS approach by solutions to business challenges, which include those found in market research, digital marketing, sales, ecommerce, and investment evaluation. Businesses utilize our productized SaaS solutions to enhance the capabilities of their professionals – from business leaders, strategy teams, analysts, marketers, category managers, to salespeople – to quickly and efficiently discover their best growth opportunities, identify potential competitive threats and make critical decisions to acquire customers and grow revenue. Our DaaS solution provides SMBs, enterprises and strategic accounts with integration of data feeds via API or other means for deployment of Similarweb Digital Data within their organizations through their own internal interfaces, and into their own software products when relevant. We provide advisory services to businesses typically at the enterprise and strategic account level that seek embedded assistance with business challenges for which we have not yet productized a solution, or for extensively customized data and analytics to accomplish their objectives using Similarweb Digital

S-8

Data. Our advisory services customers often purchase Similarweb Digital Data through our SaaS and DaaS offerings as well.

We generate revenue primarily through paid annual subscriptions to Similarweb Digital Data via our delivery methods across various pricing tiers based on feature set, geographic coverage and number of users. In addition, we have a free offering that offers access to a wide range of basic services, providing customers with a subset of the robust insights and analytics offered by our feature-rich paid subscriptions. Our free offering is intended to drive awareness and to enable potential customers to realize the value they can derive from our paid offerings.

We have a highly efficient dual-pronged sales approach with both inbound and outbound sales motions, which includes a global sales force supported by a team of technical and data experts. Our direct sales team engages with our largest customers while our inside sales team engages with our smaller customers. Following the initial sale, we engage with our customers regularly through support services, self-service product education, and proactive account management team check-ins. As part of this approach, we also seek to upsell customers to new solutions, building upon the value of Similarweb Digital Data to their business objectives and a desire to add additional feature sets, geographic coverage, users and categories of digital data and analytics solutions.

We sell to companies across a wide range of industries such as retail, consumer packaged goods, consumer finance, consultancies, marketing and advertising agencies, media and publishers, business-to-business software, payment processors, travel, and institutional investors. As of June 30, 2024, we had 5,034 paying customers.

S-10

RISK FACTORS

Investing in our securities involves a high degree of risk. In addition to the other information contained in this prospectus supplement, the accompanying prospectus and in the documents incorporated by reference herein and therein, you should carefully consider the risks discussed below and under the heading “Risk Factors” in our Annual Report on Form 20-F for the fiscal year ended December 31, 2023, filed with the SEC on February 28, 2024, or the “Annual Report”, as well as any amendment or update to our risk factors reflected in subsequent filings with the SEC, before making a decision about investing in our securities. The risks and uncertainties discussed below and in the documents incorporated by reference are not the only ones facing us. Additional risks and uncertainties not presently known to us, or that we currently see as immaterial, may also harm our business. If any of these risks occur, our business, financial condition and operating results could be harmed, the market price of our Ordinary Shares could decline and you could lose part or all of your investment.

Risks Related to this Offering and our Ordinary Shares

The market price of our Ordinary Shares may be subject to fluctuation and you could lose all or part of your investment.

Our Ordinary Shares were first offered publicly in our initial public offering in May 2021 at a price of $22.00 per share, and our Ordinary Shares have subsequently traded as high as $25.02 per share and as low as $4.54 per share through September 12, 2024. The market price of our Ordinary Shares on the New York Stock Exchange may fluctuate as a result of a number of factors, some of which are beyond our control, including, but not limited to:


			•			actual or anticipated variations in our and our competitors’ results of operations and financial condition;
			•			market acceptance of our products;
			•			general economic and market conditions and other factors, including factors unrelated to our operating performance;
			•			the mix of products that we sell and related services that we provide;
			•			changes in earnings estimates or recommendations by securities analysts, if our Ordinary Shares continue to be covered by analysts;
			•			delays between our expenditures to develop and market new or enhanced products and the generation of sales from those products;
			•			development of technological innovations or new competitive products by others;
			•			announcements of technological innovations or new products by us;
			•			developments concerning intellectual property rights, including our involvement in litigation;
			•			changes in our expenditures to develop, acquire or license new products, technologies or businesses;
			•			changes in our expenditures to promote our products;
			•			our sale or proposed sale, or the sale by our significant shareholders, of our Ordinary Shares or other securities in the future;
			•			changes in key personnel;
			•			success or failure of our research and development projects or those of our competitors; and
			•			the trading volume of our Ordinary Shares.

These factors and any corresponding price fluctuations may materially and adversely affect the market price of our Ordinary Shares and result in substantial losses being incurred by our investors. In the past, following periods of market volatility, public company shareholders have often instituted securities

S-11

class action litigation. If we were involved in securities litigation, it could impose a substantial cost upon us and divert the resources and attention of our management from our business.

Future grants of our equity awards to purchase our Ordinary Shares could reduce the market price of our Ordinary Shares.

If we or our existing shareholders, our directors or their affiliates or certain of our executive officers, sell a substantial number of our Ordinary Shares in the public market, the market price of our Ordinary Shares could decrease significantly. The perception in the public market that we or our shareholders might sell our Ordinary Shares could also depress the market price of our Ordinary Shares and could impair our future ability to obtain capital, especially through an offering of equity securities.

More specifically, we are party to an amended and restated investor rights agreement (“Investor Rights Agreement,”), dated as of October 21, 2020, which provides, among other things, that certain holders of our Ordinary Shares have the right to demand that we file a registration statement or request that their shares be covered by a registration statement that we are otherwise filing. In May 2024, we filed, and the SEC declared effective, on May 31, 2024, a shelf registration statement on Form F-3 that registered the resale of up to 15,000,000 Ordinary Shares that were then entitled to registration rights under the Investor Rights Agreement.

In addition, as of June 30, 2024, 11,141,590 Ordinary Shares were subject to outstanding option and RSU awards granted to employees and office holders under our share incentive plans, in addition to 5,866,189 Ordinary Shares issuable under currently exercisable options and RSUs. On May 20, 2021, we filed a registration statement on Form S-8 registering the issuance of up to 14,935,552 Ordinary Shares issuable under our share incentive plans, which amount included 11,227,269 Ordinary Shares issuable upon the exercise of option awards and 212,500 Ordinary Shares issuable upon the vesting of RSUs, each as previously granted under our 2012 Incentive Option Plan. In addition, such Form S-8 registered 1,495,783 Ordinary Shares issuable under our 2021 Share Incentive Plan and 2,000,000 Ordinary Shares issuable under our 2021 Employee Share Purchase Plan. On January 1, 2022, 2023, and 2024, the shares available for issuance under our 2021 Share Incentive Plan automatically increased by 3,742,272, 3,821,689 and 3,932,544 Ordinary Shares, respectively. In addition, on January 1, 2022, 2023, and 2024, the shares available for issuance under our 2021 Employee Share Purchase Plan automatically increased by 748,454, 764,338, and 786,509 Ordinary Shares, respectively. As of June 30, 2024, 21,650,653 Ordinary Shares remained available for issuance under our share incentive plans, which amount includes 11,141,590 Ordinary Shares subject to outstanding awards. Ordinary Shares included in such registration statement may be freely sold in the public market upon issuance, except for shares held by affiliates who have certain restrictions on their ability to sell.

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

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

S-12

Any additional capital raised through the sale of equity or equity-backed securities may dilute our shareholders’ ownership percentages and could also result in a decrease in the market value of our equity securities. The terms of any securities issued by us in future capital transactions may be more favorable to new investors, and may include preferences, superior voting rights and the issuance of warrants or other derivative securities, which may have a further dilutive effect on the holders of any of our securities then outstanding.

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

For as long as we are an emerging growth company, we will not be required to comply with certain requirements that apply to other public companies.

We qualify as an emerging growth company, as defined in the JOBS Act. For as long as we are an emerging growth company, which may be up to five full fiscal years from our initial public offering in 2021, we, unlike other public companies, will not be required to, among other things: (i) provide an auditor’s attestation report on management’s assessment of the effectiveness of our system of internal control over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act; (ii) comply with any new requirements adopted by the Public Company Accounting Oversight Board requiring mandatory audit firm rotation or a supplement to the auditor’s report in which the auditor would be required to provide additional information about the audit and the financial statements of the issuer; (iii) provide certain disclosures regarding executive compensation required of larger public companies; or (iv) hold nonbinding advisory votes on executive compensation and any golden-parachute payments not previously approved. In addition, the JOBS Act provides that an emerging growth company can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for adopting new or revised financial accounting standards. We intend to take advantage of the longer phase-in periods for the adoption of new or revised financial accounting standards permitted under the JOBS Act until we are no longer an emerging growth company. If we were to subsequently elect instead to comply with these public company effective dates, such election would be irrevocable pursuant to the JOBS Act.

We will remain an emerging growth company for up to five years from our initial public offering in 2021, although we will lose that status sooner if we have more than $1.235 billion of revenue in a fiscal year, have more than $700.0 million in market value of our Ordinary Shares held by non-affiliates, or issue more than $1.235 billion of non-convertible debt over a three-year period.

For so long as we rely on any of the exemptions available to emerging growth companies, you will receive less information about our executive compensation and internal control over financial reporting than issuers that are not emerging growth companies. We cannot predict whether investors will find our Ordinary Shares less attractive because we will rely on these exemptions. If some investors find our Ordinary Shares to be less attractive as a result, there may be a less active trading market for our Ordinary Shares and our share price may be more volatile.

S-13

USE OF PROCEEDS

SELLING SHAREHOLDER

The following table and footnotes set forth information with respect to the beneficial ownership of our Ordinary Shares by the selling shareholder as of September 12, 2024 and immediately after the completion of this offering by the selling shareholder. The percentages are based on 80,919,283 Ordinary Shares outstanding as of June 30, 2024, which includes 3,500,000 Shares to be sold by the selling shareholder (or 4,025,000 Shares if the underwriters exercise in full their option to purchase additional Shares).

The SEC has defined “beneficial ownership” of a security to mean the possession, directly or indirectly, of voting power and/or investment power over such security. A shareholder is also deemed to be, as of any date, the beneficial owner of all securities that such shareholder has the right to acquire within 60 days after that date through (i) the exercise of any option, warrant or right, (ii) the conversion of a security, (iii) the power to revoke a trust, discretionary account or similar arrangement, or (iv) the automatic termination of a trust, discretionary account or similar arrangement. In computing the number of shares beneficially owned by a person and the percentage ownership of that person, Ordinary Shares subject to options or other rights (as set forth above) held by that person that are currently exercisable, or will become exercisable within 60 days thereafter, are deemed outstanding, while such shares are not deemed outstanding for purposes of computing percentage ownership of any other person.

Unless the context otherwise requires, as used in this prospectus supplement, “selling shareholder” includes the selling shareholder listed below and donees, pledgees, transferees or other successors-in-interest selling shares received after the date of this prospectus supplement from the selling shareholder as a gift, pledge or other non-sale related transfer.

The information in the table below is based upon information provided by the selling shareholder. The securities owned by the selling shareholder named below do not have voting rights different from the securities owned by other security holders. Except as otherwise indicated in the table below, addresses of our directors and executive officers named below is c/o 33 Yitzhak Rabin Rd., Givatayim 5348303, Israel.

TAXATION

The following description is a general discussion of the material U.S. and Israeli tax consequences concerning the acquisition, ownership and disposition of our Ordinary Shares. It is not intended to constitute a complete analysis of all tax consequences relating to the acquisition, ownership and disposition of our Ordinary Shares. This discussion is included for general information purposes only, does not purport to be complete, and does not constitute and is not a tax opinion or tax advice to any investor. You should consult your own tax adviser concerning the tax consequences of 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

The following is a discussion of material Israeli tax consequences concerning the ownership and disposition of our Ordinary Shares purchased or held by investors. This summary 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. To the extent that the discussion is based on tax legislation that has not yet been subject to judicial or administrative interpretation, we cannot assure you that the appropriate tax authorities or the courts will 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. The discussion should not be construed as legal or professional tax advice and does not cover all possible tax considerations.

Taxation of Our Shareholders

Israeli law generally imposes a capital gain tax on the sale of capital assets by residents of Israel, as defined for Israeli tax purposes, and on the sale of assets located in Israel, including shares of Israeli companies, by both residents and non-residents of Israel, unless a specific exemption is available or unless a tax treaty between Israel and the seller’s country of residence provides otherwise.

Capital Gains Taxes Applicable to Non-Israeli Resident Shareholders. Capital gain tax is imposed on the disposition of capital assets by a non-Israeli resident if those assets are either (1) located in Israel; (2) are shares or a right to a share in an Israeli resident corporation, or (3) located outside of Israel and represent, directly or indirectly, rights to assets located in Israel. The Israeli tax law distinguishes between “Real Capital Gain” and the “Inflationary Surplus.” Real Gain is the excess of the total capital gain over Inflationary Surplus computed generally on the basis of the increase in the purchase price of the relevant asset attributable to the increase in the Israeli Consumer Price Index or, in certain circumstances, a foreign currency exchange rate, between the date of purchase and the date of disposition. Inflationary Surplus is not currently subject to tax in Israel.

Generally, Real Capital Gain accrued by individuals on the sale of our Ordinary Shares will be taxed at the rate of 25%. However, if the individual shareholder is a “substantial shareholder” at the time of sale or at any time during the preceding 12 months period, such gain will be taxed at the rate of 30%. A “substantial shareholder” is generally a person who alone or together with such person’s relative or another person who collaborates with such person on a permanent basis based on a contract, holds, directly or indirectly, at least 10% of any of the “means of control” of the corporation. “Means of control” generally include the right to vote, receive profits, nominate a director or an executive officer, receive assets upon liquidation, or order someone who holds any of the aforesaid rights how to act, regardless of the source of such right. Real Capital Gain derived by corporations will be generally subject to a corporate tax rate of 23% (in 2024). Real Capital Gains derived by a shareholder, whether an individual or a corporation that is a

S-17

dealer or trader in securities in Israel, or to whom such income is otherwise taxable as ordinary “business income” as defined in Section 2(1) of the Israeli Income Tax Ordinance (New Version), 5721-1961 (the “Tax Ordinance”), are taxed at the tax rates applicable to business income (a corporate tax rate for a corporation (23% in 2024) and a marginal tax rate of up to 47% for an individual in 2024 (excluding Surtax as discussed below)) unless contrary provisions in a relevant tax treaty apply. If the individual claims a deduction of interest and linkage fluctuation expenses in connection with the purchase or holding of the shares, the gain will generally be taxed at a fixed rate of 30% until the promulgation of regulations setting forth the rules and conditions for deduction of real interest and linkage differentials pursuant to section 101A(a)(9) and 101A(b) of the Tax Ordinance.

Generally, a non-Israeli resident (whether an individual or a corporation) who derives capital gains from the sale of shares in an Israeli resident company purchased upon or after the company was listed for trading on a stock exchange outside of Israel (such as NYSE) should be exempt from Israeli capital gains tax so long as, among others: the capital gains derived from the sale of shares was not attributed to a permanent establishment that the non-resident maintains in Israel, . However, non-Israeli “Body of Persons” (as defined in the Tax Ordinance), which includes corporations, partnerships and other entities, will not be entitled to the foregoing exemption if Israeli residents, whether directly or indirectly:

(i) have, alone or together with such person’s relatives or another person who, according to an agreement, collaborates with such person on a permanent basis regarding material affairs of the company, a controlling interest of more than 25% in any of the means of control of such non-Israeli Body of Persons or

(ii) are the beneficiaries of, or are entitled to, 25% or more of the revenues or profits of such non-Israeli Body of Persons.

Such exemption is not applicable to a person whose gains from selling or otherwise disposing of the shares are deemed to be business income according to Section 2(1) of the Tax Ordinance, as described above.

Additionally, a sale of securities by a non-Israeli resident may be exempt from Israeli capital gains tax under the provisions of an applicable tax treaty. For example, under Convention Between the Government of the United States of America and the Government of the State of Israel with respect to Taxes on Income, as amended, or the United States-Israel Tax Treaty, the sale, exchange or other disposition of shares by a shareholder who is a United States resident (for purposes of the treaty) holding the shares as a capital asset and is entitled to claim the benefits afforded to such a resident by the U.S.-Israel Tax Treaty, or a Treaty U.S. Resident, is generally exempt from Israeli capital gains tax unless, inter alia: (1) the capital gain arising from such sale, exchange or disposition is attributed to real estate located in Israel; (2) the capital gain arising from such sale, exchange or disposition is attributed to royalties; (3) the capital gain arising from the such sale, exchange or disposition is attributed to a permanent establishment in Israel that the shareholder maintains, under certain terms; (4) such Treaty U.S. Resident holds, directly or indirectly, shares representing 50% or more of the voting capital of the company during any part of the 12-month period preceding the disposition, subject to certain conditions; or (5) such Treaty U.S. Resident is an individual and was present in Israel for 183 days or more in the aggregate during the relevant taxable year. In any such case, the sale, exchange or disposition of such shares would be subject to Israeli capital gains tax, to the extent applicable; however, under the U.S.-Israel Tax Treaty, a Treaty U.S. resident would be permitted to claim a credit for the Israeli tax against the U.S. federal income tax imposed with respect to the sale, exchange or disposition, subject to the limitations in U.S. laws applicable to foreign tax credits. The U.S.-Israel Tax Treaty does not provide such credit against any U.S. state or local taxes. Application for this exemption requires appropriate documentation presented to and specific instruction received from the Israel Tax Authority (the “ITA”).

Regardless of whether shareholders may be liable for Israeli income tax on the sale of our Ordinary Shares, the payment of the consideration may be subject to withholding of Israeli tax at the source. Accordingly, shareholders may be required to demonstrate that they are exempt from tax on their

S-18

capital gains in order to avoid withholding at source at the time of sale. Specifically, in transactions involving a sale of all of the shares of an Israeli resident company, in the form of a merger or otherwise, the ITA may require from shareholders who are not liable for Israeli tax to sign declarations in forms specified by this authority or obtain a specific exemption from the ITA to confirm their status as non-Israeli resident, and, in the absence of such declarations or exemptions, may require the purchaser of the shares to withhold taxes at source.

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 up to 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. In order to benefit from the tax deferral, a pre-ruling from the ITA might be required.

Taxation of Non-Israeli Shareholders on Receipt of Dividends. Non-Israeli residents (whether individuals or corporations) are generally subject to Israeli income tax on the receipt of dividends paid on our Ordinary Shares at the rate of 25%, which tax will be withheld at source, unless relief is provided in a tax treaty between Israel and the shareholder’s country of residence (provided that a certificate from the ITA allowing for a reduced withholding tax rate or a tax exemption is obtained in advance). With respect to a person who is a “substantial shareholder” (as defined above) at the time of receiving the dividend or on any time during the preceding twelve months, the applicable tax rate is 30%. In the extent that the shares are registered with a nominee company (whether the recipient is a substantial shareholder or not) the withholding tax at source is at rate of 25% unless a lower rate is provided under an applicable tax treaty (provided that a certificate from the ITA allowing for a reduced withholding tax rate is obtained in advance). However, a distribution of dividends to non-Israeli residents is subject to tax and withholding tax at source at a rate of 20% or such lower rate as may be provided in an applicable tax treaty, subject to the receipt in advance of a valid certificate from the ITA allowing for a reduced tax rate, if the dividend is distributed from income attributed to a Preferred (including Preferred Technological) Enterprise (as such terms are defined in the Law for the Encouragement of Capital Investments, 5719-1959). If the dividend is attributable partly to income derived from a Preferred (including Preferred Technological) Enterprise, and partly to other sources of income, the withholding rate will be a blended rate reflecting the relative portions of the two types of income. We cannot assure you that we will designate the profits that we may distribute in the future in a way that will reduce shareholders’ tax liability.

However, a reduced tax rate may be provided under an applicable tax treaty (subject to the receipt in advance of a valid certificate from the ITA allowing for a reduced tax rate). For example, under the United States-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 Treaty U.S. Resident is 25%. However, generally, the maximum rate of withholding tax on dividends that are paid to a United States corporation holding 10% or more of the outstanding voting capital throughout the tax year in which the dividend is distributed as well as during the previous tax year, is 12.5%, provided that not more than 25% of the gross income for such preceding year consists of certain types of dividends and interest.

A non-Israeli resident who receives dividends from which tax was withheld is generally exempt from the obligation to file tax returns in Israel with respect to such income, provided inter alia, that (i) such income was not generated from business conducted in Israel by the taxpayer, (ii) the taxpayer has no other taxable sources of income in Israel with respect to which a tax return is required to be filed, and (iii) the taxpayer, if an individual, is not obligated to pay Surtax (as further explained below).

Surtax. Subject to the provisions of an applicable tax treaty, individuals who are subject to income tax in Israel (whether any such individual is an Israeli resident or non-Israeli resident) are also subject to an additional tax at a rate of 3% on annual income (including, but not limited to, income derived from

S-19

dividends, interest and capital gains) exceeding NIS 721,560 for 2024, which amount is linked to the annual change in the Israeli consumer price index.

Estate and Gift Tax. Israeli law presently does not impose estate or gift taxes.

Material U.S. Federal Income Tax Considerations for U.S. Holders

The following is a description of the material U.S. federal income tax considerations to the U.S. Holders defined below of owning and disposing of our Ordinary Shares. It is not a comprehensive description of all tax considerations that may be relevant to a particular U.S. Holder’s decision to acquire Ordinary Shares. This discussion applies only to a U.S. Holder that holds our Ordinary Shares as a capital asset within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended, or the Code, for tax purposes (generally, property held for investment). In addition, it does not describe all of the tax considerations that may be relevant in light of a U.S. Holder’s particular circumstances, including state and local tax considerations, any U.S. federal non-income tax considerations (such as estate or gift tax considerations), or any tax considerations relating to the alternative minimum tax or the Medicare contribution tax on net investment income. In addition, this discussion does not address any tax considerations applicable to U.S. Holders subject to special rules, such as:

•banks, insurance companies, and certain other financial institutions;

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

•dealers or traders in securities who use a mark-to-market method of tax accounting;

•persons holding Ordinary Shares as part of a hedging transaction, “straddle,” wash sale, conversion transaction or integrated transaction or persons entering into a constructive sale with respect to Ordinary Shares;

•persons whose “functional currency” for U.S. federal income tax purposes is not the U.S. dollar;

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

•tax-exempt entities or government organizations;

•S corporations, partnerships, or other entities or arrangements classified as partnerships or pass-throughs for U.S. federal income tax purposes (and investors therein);

•regulated investment companies or real estate investment trusts;

•persons who acquired our Ordinary Shares pursuant to the exercise of any employee stock option or otherwise as compensation;

•persons that own or are deemed to own (including by attribution) ten percent or more of our shares (by vote or value); and

•persons holding our Ordinary Shares in connection with a trade or business, permanent establishment, or fixed base outside the United States.

If an entity or arrangement that is classified as a partnership for U.S. federal income tax purposes holds Ordinary Shares, the U.S. federal income tax treatment of a partner will generally depend on the status of the partner and the activities of the partnership. Partnerships holding Ordinary Shares and partners in such partnerships are encouraged to consult their tax advisers as to the particular U.S. federal income tax consequences of holding and disposing of Ordinary Shares.

The discussion is based on the Code, administrative pronouncements, judicial decisions, final, temporary and proposed Treasury Regulations, all as of the date hereof, changes to any of which may affect the tax considerations described herein - possibly with retroactive effect.

A “U.S. Holder” is a holder who, for U.S. federal income tax purposes, is a beneficial owner of Ordinary Shares who is:

(1) an individual who is a citizen or resident of the United States;

(2) a corporation, or other entity taxable as a corporation, created or organized in or under the laws of the United States, any state therein or the District of Columbia;

S-20

(3) an estate, the income of which is subject to U.S. federal income taxation regardless of its source; or

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

U.S. Holders are encouraged to consult their tax advisers concerning the U.S. federal, state, local and non-U.S. tax consequences of owning and disposing of our Ordinary Shares in their particular circumstances.

Passive Foreign Investment Company Rules

A non-U.S. corporation will be classified as a PFIC for any taxable year in which, after applying certain look-through rules, either:

•at least 75% of its gross income is passive income (such as interest income); or

•at least 50% of its gross assets (determined on the basis of a quarterly average) is attributable to assets that produce passive income or are held for the production of passive income (including cash).

For this purpose, cash is a passive asset and passive income generally includes dividends, interest, royalties and rents (other than certain royalties and rents derived in the active conduct of a trade or business and not derived from a related person). For purposes of this test, we will be treated as owning our proportionate share of the assets and earning our proportionate share of the income of any other corporation, the equity of which we own, directly or indirectly, 25% or more (by value).

Based on the estimated composition of our income, assets and operations, we do not believe that we were classified as a PFIC for the U.S. federal income tax purposes for the taxable year ending December 31, 2023. No assurances can be provided that we will not be a PFIC for the current or any future taxable year or that we have not been a PFIC in any prior taxable years. The determination of whether we are a PFIC is a fact-intensive determination made on an annual basis and the applicable law is subject to varying interpretation. In particular, the composition of our assets may depend in part on our current and intended future business plans, which are subject to change. In addition, for our current and future taxable years, the aggregate fair market value of our assets, including goodwill and other unbooked intangibles for PFIC testing purposes may be determined in part by reference to the market price of our Ordinary Shares from time to time, which may fluctuate considerably. Under the income test, our status as a PFIC depends on the composition of our income which will depend on a variety of factors that are subject to uncertainty, including transactions we enter into in the future. There can be no assurance that the IRS would not successfully challenge our position. Accordingly, our U.S. counsel expresses no opinion with respect to our PFIC status for any prior, current or future taxable year.

If we are classified as a PFIC in any year with respect to which a U.S. Holder owns the 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 the Ordinary Shares, regardless of whether we continue to meet the tests described above unless (1) we cease to be a PFIC and the U.S. Holder has made a “deemed sale” election under the PFIC rules, or (2) the U.S. Holder (A) makes a “QEF Election” (defined below) or (B) is eligible to make and makes a mark-to-market election (as described below), with respect to all taxable years during such U.S. Holder’s holding period in which we are a PFIC. If such a deemed sale election is made, a U.S. Holder will be deemed to have sold the Ordinary Shares the U.S. Holder holds at their fair market value as of the date of such deemed sale and any gain from such deemed sale would be subject to the rules described below. After the deemed sale election, so long as we do not become a PFIC in a subsequent taxable year, the U.S. Holder’s Ordinary Shares with respect to which such election was made will not be treated as shares in a PFIC and the U.S. Holder will not be subject to the rules described below with respect to any “excess distribution” the U.S. Holder receives from us or any gain from an actual sale or other disposition of the Ordinary Shares. U.S. Holders should consult their tax advisers as to the possibility and

S-21

consequences of making a deemed sale election if we are (or were to become) and then cease to be a PFIC and such election becomes available.

For each taxable year we are treated as a PFIC with respect to U.S. Holders, U.S. Holders will be subject to special tax rules with respect to any “excess distribution” such U.S. Holder receives and any gain such U.S. Holder recognizes from a sale or other disposition (including a pledge) of Ordinary Shares, unless (1) such U.S. Holder makes a “qualified electing fund” election, or QEF Election, with respect to all taxable years during such U.S. Holder’s holding period in which we are a PFIC, or (2) our Ordinary Shares constitute “marketable stock” and such U.S. Holder makes a mark-to-market election (as discussed below). Distributions a U.S. Holder receives in a taxable year that are greater than 125% of the average annual distributions a U.S. Holder received during the shorter of the three preceding taxable years or the U.S. Holder’s holding period for the Ordinary Shares will be treated as an excess distribution. Under these special tax rules:

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

•the amount allocated to the current taxable year, and any taxable year prior to the first taxable year in which we became a PFIC, will be treated as ordinary income; and

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

The tax liability for amounts allocated to years prior to the year of disposition or “excess distribution” cannot be offset by any net operating losses for such years, and gains (but not losses) realized on the sale of the Ordinary Shares cannot be treated as capital gains, even if a U.S. Holder holds the Ordinary Shares as capital assets.

If we are a PFIC, a U.S. Holder will generally be subject to similar rules with respect to distributions we receive from, and our dispositions of the shares of, any of the foreign entities in which we may hold equity interests that also are PFICs, or lower-tier PFICs, as if such distributions were indirectly received by, and/or dispositions were indirectly carried out by, such U.S. Holder. U.S. Holders should consult their tax advisers regarding the application of the PFIC rules to our subsidiaries.

If a U.S. Holder makes an effective QEF Election, the U.S. Holder will be required to include in gross income each year, whether or not we make distributions, as capital gains, such U.S. Holder’s pro rata share of our net capital gains and, as ordinary income, such U.S. Holder’s pro rata share of our earnings in excess of our net capital gains. However, a U.S. Holder can only make a QEF Election with respect to Ordinary Shares in a PFIC if such company agrees to furnish such U.S. Holder with certain tax information annually. We do not currently expect to provide such information in the event that we are classified as a PFIC.

U.S. Holders can avoid the interest charge on excess distributions or gain relating to our Ordinary Shares by making a mark-to-market election with respect to the Ordinary Shares, provided that the Ordinary Shares are “marketable stock.” Ordinary Shares will be marketable stock if they are “regularly traded” on certain U.S. stock exchanges (such as NYSE) or on a non-U.S. stock exchange that meets certain conditions. For these purposes, the Ordinary Shares will be considered regularly traded during any calendar year during which they are traded, other than in de minimis quantities, on at least 15 days during each calendar quarter. Any trades that have as their principal purpose meeting this requirement will be disregarded. Each U.S. Holder should consult its tax adviser as to the whether a mark-to-market election is available or advisable with respect to the Ordinary Shares.

A U.S. Holder that makes a mark-to-market election must include in ordinary income for each year an amount equal to the excess, if any, of the fair market value of our Ordinary Shares at the close of the taxable year over the U.S. Holder’s adjusted tax basis in the Ordinary Shares. An electing holder may

S-22

also claim an ordinary loss deduction for the excess, if any, of the U.S. Holder’s adjusted basis in the Ordinary Shares over the fair market value of the Ordinary Shares at the close of the taxable year, but this deduction is allowable only to the extent of any net mark-to-market gains for prior years. Gains from an actual sale or other disposition of the Ordinary Shares will be treated as ordinary income, and any losses incurred on a sale or other disposition of the shares will be treated as an ordinary loss to the extent of any net mark-to-market gains for prior years. Once made, the election cannot be revoked without the consent of the IRS unless the Ordinary Shares cease to be marketable stock.

However, a mark-to-market election generally cannot be made for equity interests in any lower-tier PFICs that we own, unless shares of such lower- tier PFIC are themselves “marketable stock.” As a result, even if a U.S. Holder validly makes a mark-to-market election with respect to our Ordinary Shares, the U.S. Holder would likely continue to be subject to the PFIC rules (described above) with respect to its indirect interest in any of our investments that are treated as an equity interest in a PFIC for U.S. federal income tax purposes. U.S. Holders should consult their tax advisers 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.

Unless otherwise provided by the U.S. Treasury, each U.S. shareholder of a PFIC is required to file an annual report containing such information as the U.S. Treasury may require. A U.S. Holder’s failure to file the annual report will cause the statute of limitations for such U.S. Holder’s U.S. federal income tax return to remain open with regard to the items required to be included in such report until three years after the U.S. Holder files the annual report, and, unless such failure is due to reasonable cause and not willful neglect, the statute of limitations for the U.S. Holder’s entire U.S. federal income tax return will remain open during such period. U.S. Holders should consult their tax advisers regarding the requirements of filing such information returns under these rules.

WE STRONGLY URGE YOU TO CONSULT YOUR TAX ADVISER REGARDING THE IMPACT OF OUR PFIC STATUS ON YOUR INVESTMENT IN THE ORDINARY SHARES AS WELL AS THE APPLICATION OF THE PFIC RULES TO YOUR INVESTMENT IN THE ORDINARY SHARES.

Taxation of Distributions

Subject to the discussion above under “-Passive foreign investment company rules,” distributions paid on Ordinary Shares, other than certain pro rata distributions of Ordinary Shares, will generally be treated as dividends to the extent paid out of our current or accumulated earnings and profits (as determined under U.S. federal income tax principles). Because we do not calculate our earnings and profits under U.S. federal income tax principles, distributions, will be reported to U.S. Holders as dividends. Non-corporate U.S. holders may qualify for the preferential rates of taxation applicable to long term capital gains (i.e., gains from the sale of capital assets held for more than one year) with respect to dividends on Ordinary Shares if we are a “qualified foreign corporation,” provided that certain conditions are met, including conditions relating to holding period and the absence of certain risk reduction transactions. A non-United States corporation (other than a corporation that is classified as a PFIC for the taxable year in which the dividend is paid or the preceding taxable year) generally will be considered to be a qualified foreign corporation (a) if it is eligible for the benefits of a comprehensive tax treaty with the United States which the Secretary of Treasury of the United States determines is satisfactory for purposes of these rules and which includes an exchange of information provision, or (b) with respect to any dividend it pays on Ordinary Shares which are readily tradable on an established securities market in the United States. The amount of the dividend will be treated as foreign-source dividend income to U.S. Holders and will not be eligible for the dividends-received deduction generally available to U.S. corporations under the Code. Dividends will generally be included in a U.S. Holder’s income on the date of the U.S. Holder’s receipt of the dividend. The amount of any distribution of property other than cash (and other than certain pro rata distributions of Ordinary Shares or rights to acquire Ordinary Shares) will be the fair market value of such property on the date of distribution. For foreign tax credit purposes, our dividends will generally be treated as passive category income. If the dividends qualify for preferential rates as discussed above, the amount of

S-23

the dividend taken into account for purposes of calculating the foreign tax credit limitation will generally be limited to the gross amount of the dividend, multiplied by the reduced rate applicable to the qualified dividend income, divided by the highest rate of tax normally applicable to dividends. In addition, applicable U.S. Treasury regulations may restrict the availability of any foreign tax credit based on the nature of the withholding tax imposed by a non-U.S. jurisdiction. The rules relating to the determination of the U.S. foreign tax credit are complex, and U.S. Holders should consult their tax advisers regarding the availability of a foreign tax credit in their particular circumstances and the possibility of claiming a deduction (in lieu of the foreign tax credit) for any foreign taxes paid or withheld.

The amount of any distribution paid in foreign currency will be equal to the U.S. dollar value of such currency, translated at the spot rate of exchange on the date such distribution is actually or constructively received by the U.S. Holder, regardless of whether the payment is in fact converted into U.S. dollars at that time. A U.S. Holder generally should not recognize any foreign currency gain or loss in respect of such distribution if such foreign currency is converted into U.S. dollars on the date received by the U.S. Holder.

Sale or Other Taxable Disposition of Ordinary Shares

Subject to the discussion above under “-Passive foreign investment company rules,” gain or loss realized on the sale or other taxable disposition of Ordinary Shares will be capital gain or loss, and will be long-term capital gain or loss if the U.S. Holder held the Ordinary Shares for more than one year. The amount of the gain or loss will equal the difference between the U.S. Holder’s tax basis in the Ordinary Shares disposed of and the amount realized on the disposition, in each case as determined in U.S. dollars. This gain or loss will generally be U.S.-source gain or loss for foreign tax credit purposes. The deduction for capital losses is subject to limitations. Because gains for the sale or other taxable disposition of Ordinary Shares will generally be treated as U.S.-source income, and subject to certain exceptions, Treasury Regulations generally preclude U.S taxpayers from claiming a foreign tax credit with respect to any non-U.S tax imposed on any on gains from dispositions of shares held as capital assets unless the tax is creditable under an applicable income tax treaty. Accordingly, your ability to claim a foreign tax credit with respect to the Israeli tax imposed on any such sale or other taxable disposition, if any, may be significantly limited. In addition, applicable U.S. Treasury regulations may restrict the availability of any foreign tax credit based on the nature of the withholding tax imposed by a non-U.S. jurisdiction. You should consult your tax adviser as to whether the Israeli tax on gains may be creditable or deductible in light of your particular circumstances and your ability to apply the provisions of an applicable treaty.

If the consideration received upon the sale or other taxable disposition of Ordinary Shares is paid in foreign currency, the amount realized will be the U.S. dollar value of the payment received, translated at the spot rate of exchange on the date of taxable sale, exchange or disposition. If our Ordinary Shares are treated as traded on an established securities market, a cash basis U.S. Holder and an accrual basis U.S. Holder who has made a special election (which must be applied consistently from year to year and cannot be changed without the consent of the IRS) will determine the U.S. dollar value of the amount realized in foreign currency by translating the amount received at the spot rate of exchange on the settlement date of the sale. An accrual basis United States Holder that does not make the special election will recognize exchange gain or loss to the extent attributable to the difference between the exchange rates on the sale date and the settlement date, and such exchange gain or loss generally will constitute ordinary income or loss. U.S. Holders should consult their tax advisers regarding how to account for gain or loss on the sale, exchange or disposition of the Ordinary Shares that are paid in a currency other than the U.S. dollar.

A U.S. Holder’s basis in Ordinary Shares will generally be the U.S. dollar value of the acquisition cost of such Ordinary Shares. If a U.S. Holder uses foreign currency to purchase Ordinary Shares, the cost of such Ordinary Shares will be the U.S. dollar value of the foreign currency purchase price determined by reference to the spot rate of exchange on the date of purchase. However, if the Ordinary Shares are treated as traded on an established securities market and the U.S. Holder is either a cash basis taxpayer or an accrual basis taxpayer who has made the special election described above, such U.S. Holder will determine

S-24

the U.S. dollar value of the cost of such Ordinary Shares by translating the amount paid at the spot rate of exchange on the settlement date of the purchase.

Information reporting and backup withholding

Payments of dividends and sales proceeds that are made within the United States or through certain U.S.-related financial intermediaries generally are subject to information reporting, and may be subject to backup withholding, unless (1) the U.S. Holder is a corporation or other exempt recipient or (2) in the case of backup withholding, the U.S. Holder provides a correct taxpayer identification number and certifies that it is not subject to backup withholding.

Backup withholding is not an additional tax. The amount of any backup withholding from a payment to a U.S. Holder will be allowed as a credit against the holder’s U.S. federal income tax liability and may entitle it to a refund, provided that the required information is timely furnished to the IRS.

Information with respect to foreign financial assets

Certain U.S. Holders who are individuals (and, under proposed regulations, certain entities) may be required to report information relating to the Ordinary Shares, subject to certain exceptions (including an exception for Ordinary Shares held in accounts maintained by certain U.S. financial institutions). Such U.S. Holders who fail to timely furnish the required information may be subject to a penalty and the statute of limitations on the assessment and collection of all U.S. federal income taxes of such U.S. Holder for the related tax year may not close before the date which is three years after the date on which such report is filed. Additionally, if a U.S. Holder does not file the required information, the statute of limitations with respect to tax returns of the U.S. Holder to which the information relates may not close until three years after such information is filed. U.S. Holders should consult their tax advisers regarding their reporting obligations with respect to their ownership and disposition of the Ordinary Shares.

S-25

UNDERWRITING

The company, the selling shareholder and the underwriters named below have entered into an underwriting agreement with respect to the shares being offered. Subject to certain conditions, each underwriter has severally agreed to purchase the number of shares indicated in the following table.

Goldman Sachs & Co. LLC is the representative of the underwriters.


Underwriters			Number of Shares
Goldman Sachs & Co. LLC...…....................................................................			1,540,000
Barclays Capital Inc....…...............................................................................			770,000
Citizens JMP Securities, LLC...….................................................................			420,000
William Blair & Company, L.L.C....….........................................................			420,000
Needham & Company LLC...…....................................................................			350,000
Total...…........................................................................................................			3,500,000

The underwriters are committed to take and pay for all of the Shares being offered by the selling shareholder, if any are taken, other than the Shares covered by the option described below unless and until this option is exercised.

The underwriters have an option to buy up to an additional 525,000 Shares from the selling shareholder to cover sales by the underwriters of a greater number of Shares than the total number set forth in the table above. They may exercise that option for 30 days. If any Shares are purchased pursuant to this option, the underwriters will severally purchase Shares in approximately the same proportion as set forth in the table above.

The following table shows the per share and total underwriting discounts and commissions to be paid to the underwriters by the selling shareholder. Such amounts are shown assuming both no exercise and full exercise of the underwriters’ option to purchase 525,000 additional shares.


	Per Share	No Exercise	Full Exercise
Public offering price……………………………………….....	$7.85	$27,475,000	$31,596,250.00
Underwriting discount………………………………………..	$0.3925	$1,373,750	$1,579,812.50
Proceeds, before expenses, to the selling shareholder….........	$7.4575	$26,101,250	$30,016,437.50

Shares sold by the underwriters to the public will initially be offered at the public offering price set forth on the cover of this prospectus supplement. Any Shares sold by the underwriters to securities dealers may be sold at a discount of up to $0.2355 per share from the public offering price. After the initial offering of the Shares, the representatives may change the offering price and the other selling terms. The offering of the Shares by the underwriters is subject to receipt and acceptance and subject to the underwriters’ right to reject any order in whole or in part.

The company and other parties have agreed with the underwriters, subject to certain exceptions, not to dispose of or hedge any of their Shares or securities convertible into or exchangeable for Shares during the period from the date of this prospectus supplement continuing through the date 45 days after the date of this prospectus supplement, except with the prior written consent of the representative. This agreement does not apply to any existing employee benefit plans. See “Shares Available for Future Sale” for a discussion of certain transfer restrictions.

In connection with the offering, the underwriters may purchase and sell Shares in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created

S-26

by short sales. Short sales involve the sale by the underwriters of a greater number of shares than they are required to purchase in the offering, and a short position represents the amount of such sales that have not been covered by subsequent purchases. A “covered short position” is a short position that is not greater than the amount of additional shares for which the underwriters’ option described above may be exercised. The underwriters may cover any covered short position by either exercising their option to purchase additional shares or purchasing shares in the open market. In determining the source of shares to cover the covered short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase additional shares pursuant to the option described above. “Naked” short sales are any short sales that create a short position greater than the amount of additional shares for which the option described above may be exercised. The underwriters must cover any such naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the Ordinary Shares in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of various bids for or purchases of Ordinary Shares made by the underwriters in the open market prior to the completion of the offering.

The underwriters may also impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the underwriters have repurchased shares sold by or for the account of such underwriter in stabilizing or short covering transactions.

Purchases to cover a short position and stabilizing transactions, as well as other purchases by the underwriters for their own accounts, may have the effect of preventing or retarding a decline in the market price of the company’s Ordinary Shares, and together with the imposition of the penalty bid, may stabilize, maintain or otherwise affect the market price of the Ordinary Shares. As a result, the price of the Ordinary Shares may be higher than the price that otherwise might exist in the open market. The underwriters are not required to engage in these activities and may end any of these activities at any time. These transactions may be effected on the NYSE, in the over-the-counter market or otherwise.

The company estimates that its share of the total expenses of the offering, excluding underwriting discounts and commissions, will be approximately $325,000. The company has also agreed to reimburse the underwriters for certain of their expenses in an amount up to $40,000.

The company and the selling shareholder have agreed to indemnify the several underwriters against certain liabilities, including liabilities under the Securities Act of 1933.

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include sales and trading, commercial and investment banking, advisory, investment management, investment research, principal investment, hedging, market making, brokerage and other financial and non-financial activities and services. Certain of the underwriters and their respective affiliates have provided, and may in the future provide, a variety of these services to the company and to persons and entities with relationships with the company, for which they received or will receive customary fees and expenses.

In the ordinary course of their various business activities, the underwriters and their respective affiliates, officers, directors and employees may purchase, sell or hold a broad array of investments and actively traded securities, derivatives, loans, commodities, currencies, credit default swaps and other financial instruments for their own account and for the accounts of their customers, and such investment and trading activities may involve or relate to assets, securities and/or instruments of the company (directly, as collateral securing other obligations or otherwise) and/or persons and entities with relationships with the company. The underwriters and their respective affiliates may also communicate independent investment recommendations, market color or trading ideas and/or publish or express independent research views in respect of such assets, securities or instruments and may at any time hold, or recommend to clients that they should acquire, long and/or short positions in such assets, securities and instruments.

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 supplement. This prospectus supplement, the accompanying prospectus and any additional prospectus supplement(s) do not contain all the information contained in the registration statement, including its exhibits and schedules. You should refer to the registration statement, including its exhibits and schedules, for further information about us and the securities we may offer. Statements we make in this prospectus supplement, the accompanying prospectus and any additional prospectus supplements(s) about certain contracts or other documents are not necessarily complete. When we make such statements, we refer you to the copies of the contracts or documents that are filed as exhibits to the registration statement, because those statements are qualified in all respects by reference to those exhibits. The registration statement, including exhibits and schedules, is on file at the office of the SEC and may be inspected without charge.

We are subject to the information reporting requirements of the Exchange Act. Under the Exchange Act, we are required to file annual and special reports and other information with the SEC. As a foreign private issuer, we are exempt from the rules under the Exchange Act prescribing the furnishing and content of proxy statements and our officers, directors and principal shareholders are exempt from the reporting and short-swing profit recovery provisions contained in Section 16 of the Exchange Act. In addition, we are not required under the Exchange Act to file annual, quarterly and current reports and financial statements as frequently or as promptly as U.S. companies whose securities are registered under the Exchange Act. However, we file with the SEC, within 120 days after the end of each fiscal year, or such applicable time as required by the SEC, an annual report on Form 20-F containing financial statements audited by an independent registered public accounting firm, and we submit to the SEC, on Form 6-K, unaudited quarterly financial information.

We file reports, proxy statements and other information with the SEC. The SEC maintains a web site that contains reports, proxy and information statements and other information about issuers, such as us, who file electronically with the SEC. The address of that website is http://www.sec.gov.

We maintain a corporate website at www.similarweb.com. Information contained on, or that can be accessed through, our website does not constitute a part of this prospectus supplement. We have included our website address in this prospectus supplement solely as an inactive textual reference.

INCORPORATION OF CERTAIN INFORMATION BY REFERENCE

The SEC allows us to “incorporate by reference” into this prospectus supplement the information in documents we file with it. This means that we can disclose important information to you by referring you to another document filed by us with the SEC. Each document incorporated by reference is current only as of the date of such document, and the incorporation by reference of such documents shall not create any implication that there has been no change in our affairs since the date thereof or that the information contained therein is current as of any time subsequent to its date. The information incorporated by reference is considered to be a part of this prospectus supplement and should be read with the same care. When we update the information contained in documents that have been incorporated by reference by making future filings with the SEC, the information incorporated by reference in this prospectus supplement is considered to be automatically updated and superseded. In other words, in the case of a conflict or inconsistency between information contained in this prospectus supplement and information incorporated by reference into this prospectus supplement, you should rely on the information contained in the document that was filed later.

We incorporate by reference into this prospectus supplement documents listed below and any future filings made with the SEC under Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act, and, to the

ENFORCEABILITY OF CIVIL LIABILITIES

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

We have been informed by our legal counsel in Israel, Meitar | Law Offices, that it may be difficult to assert U.S. securities law claims in original actions instituted in Israel. Israeli courts may refuse to hear a claim based on an alleged violation of U.S. securities laws because Israel is not the most appropriate forum in which 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 proven as a fact which can be a time-consuming and costly process. Certain matters of procedure will also be governed by Israeli law.

We have irrevocably appointed Similarweb, 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 the offerings under this prospectus supplement or any purchase or sale of securities in connection with any such offering(s). 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 a judgment based upon the civil liability provisions of the Securities Act or the Exchange Act and including a monetary or compensatory judgment in a non-civil matter, provided that, among other things:

•

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

•

the prevailing law of the foreign state in which the judgment is rendered allows for the enforcement of judgments of Israeli courts;

•

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, in the opinion of the Israeli court;

•

the judgment is not contrary to public policy of Israel, and the enforcement of the civil liabilities set forth in the judgment is not likely to impair the security or sovereignty of Israel;

•

the judgment was not obtained by fraud and does 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 was not pending in any Israeli court or tribunal at the time at which the lawsuit was instituted in the foreign court; and

•

the judgment is enforceable according to the laws of Israel and according to the law of the foreign state in which the relief was granted.

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.
