The following summary contains a description of certain Cayman Islands and U.S. federal income tax consequences of the acquisition, ownership and disposition of our Class A common shares. It does not purport to be a comprehensive description of all the tax considerations that may be relevant to a decision to hold the Class A common shares, is not applicable to all categories of investors, some of which may be subject to special rules, and does not address all of the Cayman Islands and U.S. federal income tax considerations applicable to any particular holder. The summary is based upon the tax laws of the Cayman Islands and regulations thereunder and on the tax laws of the United States and regulations thereunder and the other authorities described below as of the date hereof, which are subject to change.

Holders of our Class A common shares should consult their own tax advisors about the particular Cayman Islands and U.S. federal, state, local and other tax consequences to them of the acquisition, ownership and disposition of our Class A common shares.

Cayman Islands Tax Considerations

Pursuant to section 6 of the Tax Concessions Act (as revised) of the Cayman Islands, we have obtained an undertaking from the Governor-in-Cabinet that:

(a) No law which is enacted in the Cayman Islands imposing any tax to be levied on profits or income or gains or appreciations shall apply to us or our operations; and

(b) No tax be levied on profits, income, gains or appreciations or which is in the nature of estate duty or inheritance tax shall be payable by us: (i) on or in respect to our shares, debentures or other obligations; or (ii) by way of withholding in whole or in part of any relevant payment as defined in section 6(3) of the Tax Concessions Act (as revised).

Our undertaking is for a period of 20 years from April 26, 2016.

The Cayman Islands currently levy no taxes on individuals or corporations based upon profits, income, gains or appreciations and there is no taxation in the nature of inheritance tax or estate duty. There are no other taxes likely to be material to us levied by the Government of the Cayman Islands save for certain stamp duties which may be applicable, from time to time, on certain instruments.

Payments of dividends and capital in respect of our Class A common shares will not be subject to taxation in the Cayman Islands and no withholding will be required on the payment of a dividend or capital to any holder of our Class A common shares, nor will gains derived from the disposal of our Class A common shares be subject to Cayman Islands income or corporation tax.

There is no income tax treaty or convention currently in effect between the United States and the Cayman Islands.

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

The following section is a description of the material U.S. federal income tax consequences of the ownership and disposition of our Class A common shares, but it does not purport to be a comprehensive description of all of the tax considerations that may be relevant to a particular person’s decision to hold our shares.

This summary applies only to U.S. Holders (as defined below) that hold our Class A common shares as capital assets for tax purposes. In addition, it does not describe all of the tax consequences that may be relevant in light of a U.S. Holder’s particular circumstances, including alternative minimum tax consequences, the potential application of the provisions of the Internal Revenue Code of 1986, as amended, or the “Code,” known as the Medicare contribution tax, and tax consequences applicable to U.S. Holders subject to special rules, such as:

•Certain financial institutions.

•Insurance companies.

•Real estate investment trusts or regulated investment companies.

•Dealers or traders in securities that use a mark-to-market method of tax accounting.

•Persons holding Class A common shares as part of a hedging transaction, straddle, wash sale, conversion transaction or other integrated transaction or persons entering into a constructive sale with respect to the Class A common shares.

•Persons whose functional currency for U.S. federal income tax purposes is not the U.S. dollar.

•Tax-exempt entities, including an “individual retirement account” or “Roth IRA”.

•Persons that own or are deemed to own ten percent or more of our Class A common shares, by vote or value.

•Persons holding our Class A common shares in connection with a trade or business conducted outside of the United States.

•Partnerships or other entities or arrangements treated as partnerships for U.S. federal income tax purposes.

If an entity that is classified as a partnership for U.S. federal income tax purposes holds our Class A common 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 our Class A common shares and partners in such partnerships should consult their tax advisers as to the particular U.S. federal income tax consequences of owning and disposing of the Class A common shares.

This discussion is based on the Code, administrative pronouncements, judicial decisions, final, temporary and proposed Treasury regulations, all as of the date hereof, any of which is subject to change or differing interpretations, possibly with retroactive effect.

A “U.S. Holder” is a holder who, for U.S. federal income tax purposes, is a beneficial owner of our Class A common shares and is:

•An individual that is a citizen or resident of the United States;

•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; or

•An estate or trust the income of which is subject to U.S. federal income taxation regardless of its source.

U.S. Holders should consult their tax advisers concerning the U.S. federal, state, local and non-U.S. tax consequences of owning and disposing of our Class A common shares in their particular circumstances.

This discussion assumes that we were not a PFIC for our 2024 taxable year, as described below.

Taxation of Distributions

As discussed above under “Item 8. Financial Information—A. Consolidated statements and other financial information—Dividends and dividend policy,” we do not currently intend to pay dividends. In the event that we do pay dividends, and subject to the discussion below under “—Passive Foreign Investment Company Rules” distributions paid on our Class A common shares, other than certain pro rata distributions of Class A common shares, will 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 maintain calculations of our earnings and profits under U.S. federal income tax principles, we expect that distributions generally will be reported to U.S. Holders as dividends. Subject to applicable limitations (including as discussed below under “—Passive Foreign Investment Company Rules,”), dividends paid to certain non-corporate U.S. Holders may be eligible for taxation as “qualified dividend income” and therefore may be taxable at rates applicable to long-term capital gains so long as our Class A common shares are listed and trade on Nasdaq or are readily tradable on another established securities market in the United States. U.S. Holders should consult their tax advisers regarding the availability of the reduced tax rate on dividends in their particular circumstances.

The amount of a dividend will generally be treated as non-U.S.-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 be included in a U.S. Holder’s income on the date of the U.S. Holder’s receipt of the dividend.

Sale or Other Disposition of Common Shares

Subject to the discussion below under “—Passive Foreign Investment Company Rules”, for U.S. federal income tax purposes, gain or loss realized on the sale or other disposition of our Class A common shares will be capital gain or loss, and will be long-term capital gain or loss if the U.S. Holder held the Class A common 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 Class A common 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 deductibility of capital losses is subject to various limitations.

Passive Foreign Investment Company Rules

A non-U.S. corporation will be a PFIC for any taxable year in which either (i) 75% or more of its gross income consists of “passive income”, or (ii) 50% or more of the average quarterly value of its assets consist of assets that produce, or are held for the production of, “passive income”. For this purpose, subject to certain exceptions, passive income includes interest, dividends, rents, and certain gains from transactions. Cash is a passive asset for these purposes. A non-U.S. corporation will be treated as owning its proportionate share of the assets and earning its proportionate share of the income of any other corporation in which it owns, directly or indirectly, more than 25% (by value) of the stock.

The determination of whether we are, or will be, a PFIC for a taxable year depends on the application of complex U.S. federal income tax rules, which are subject to various interpretations. While the applicability of the PFIC rules to us is not clear in light of our evolving business activities and the lack of clarity with respect to certain aspects of the rules, based on the composition of our income and assets, including goodwill, we do not believe that we were a PFIC for our 2024 taxable year. Our PFIC status is a factual determination that is made on an annual basis. Because our PFIC status for any taxable year will depend on the manner in which we operate our business, the composition of our income and assets, including the relative growth of our income resulting from our credit activities and the payment processing services we provide, and the value of our assets from time to time, there can be no assurance that we will not be a PFIC for any taxable year. In particular, we note that growth in our credit-related activities relative to our other business lines has increased the risk that we may be treated as a PFIC and, if such growth continues, may result in us being treated as a PFIC in future years. Uncertainty with respect to certain aspects of the PFIC rules and changes to these rules (including the finalization of proposed rules) may also affect our PFIC status. In addition, our PFIC status may depend, in part, on the average value of our goodwill and other intangible assets. Fluctuations in our market capitalization may affect our PFIC status if the value of our assets for purposes of the asset test, including the value of our goodwill and other intangibles, is determined by reference to our market capitalization from time to time (which has been, and may continue to be, volatile), rather than based on other methods. Moreover, there can be no assurance that the Internal Revenue Service, or the “IRS.” will agree with our conclusion.

If we were a PFIC for any year during which a U.S. Holder holds our Class A common shares, we generally would continue to be treated as a PFIC with respect to that U.S. Holder for all succeeding years during which the U.S. Holder holds Class A common shares, even if we ceased to meet the threshold requirements for PFIC status.

If we were a PFIC for any taxable year and any of our subsidiaries, consolidated affiliated entities or other companies in which we own or are treated as owning equity interests were also a PFIC (any such entity, a “Lower-tier PFIC”), U.S. Holders would be deemed to own a proportionate amount (by value) of the shares of each Lower-tier PFIC and would be subject to U.S. federal income tax according to the rules described in the subsequent paragraph on (i) certain distributions by a Lower-tier PFIC and (ii) dispositions of shares of Lower-tier PFICs, in each case as if the U.S. Holders held such shares directly, even though the U.S. Holders had not received the proceeds of those distributions or dispositions.

If we were a PFIC for any taxable year during which a U.S. Holder held our Class A common shares, the U.S. Holder may be subject to adverse tax consequences. Generally, gain recognized upon a disposition (including, under certain circumstances, a pledge) of our Class A common shares by the U.S. Holder would be allocated ratably over the U.S. Holder’s holding period for such shares. The amounts allocated to the taxable year of disposition and to any year before we became a PFIC would be taxed as ordinary income. The amount allocated to each other taxable year would be subject to tax at the highest rate in effect for individuals or corporations, as appropriate, for that taxable year and an interest charge would be imposed on the tax on such amount. Further, to the extent that any distribution received by a U.S. Holder on its Class A common shares exceeds 125% of the average of the annual distributions on the Class A common shares received during the preceding three years or the U.S. Holder’s holding period, whichever is shorter, that distribution would be subject to taxation in the same manner as gain, described immediately above.

In addition, if we were a PFIC or, with respect to a particular U.S. Holder, were treated as a PFIC for the taxable year in which we paid a dividend or for the prior taxable year, the preferential dividend rates discussed above with respect to dividends paid to certain non-corporate U.S. Holders would not apply.

Alternatively, if we were a PFIC and if our Class A common shares were “regularly traded” on a “qualified exchange”, a U.S. Holder could make a mark-to-market election that would result in tax treatment different from the general tax treatment for PFICs described above. Our Class A common shares would be treated as “regularly traded” in any calendar year in which more than a de minimis quantity of our Class A common shares were traded on a qualified exchange on at least 15 days during each calendar quarter. The Nasdaq is a qualified exchange for this purpose.

If a U.S. Holder makes a mark-to-market election, the holder generally will recognize as ordinary income any excess of the fair market value of its Class A common 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 Class A common 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 the mark-to-market election). If a U.S. Holder makes the election, the holder’s tax basis in the Class A common shares will be adjusted to reflect these income or loss amounts. Any gain recognized on the sale or other disposition of Class A common shares in a year when we are a PFIC with respect to our U.S. shareholders 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 the mark-to-market election). Because the mark-to-market election only applies to marketable stock, however, it would not apply to a U.S. Holder’s indirect interest in any of our subsidiaries that were also determined to be PFIC.

If a U.S. Holder owns Class A common shares during any year in which we are a PFIC, the holder generally must file an annual report containing such information as the U.S. Treasury may require on IRS Form 8621 (or any successor form) with respect to us, generally with the holder’s federal income tax return for that year.

U.S. Holders should consult their tax advisers concerning our potential PFIC status and the potential application of the PFIC rules.

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 (i) the U.S. Holder is a corporation or other exempt recipient or (ii) 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 such 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. U.S. Holders should consult their tax advisers regarding the application of the U.S. information reporting and backup withholding rules.

Information with Respect to Foreign Financial Assets

Certain U.S. Holders who are individuals (and certain entities) may be required to report information on their U.S. federal income tax returns relating to an interest in our Class A common shares, subject to certain exceptions (including an exception for Class A common shares held in accounts maintained by certain U.S. financial institutions). U.S. Holders should consult their tax advisers regarding the effect, if any, of this requirement on their ownership and disposition of the Class A common shares.

THE ABOVE DESCRIPTION IS NOT INTENDED TO CONSTITUTE A COMPLETE ANALYSIS OF ALL TAX CONSEQUENCES RELATING TO THE OWNERSHIP AND DISPOSITION BY U.S. HOLDERS OF OUR CLASS A COMMON SHARES. U.S. HOLDERS SHOULD CONSULT THEIR OWN TAX ADVISORS CONCERNING THE TAX CONSEQUENCES OF THEIR PARTICULAR SITUATION.
