Canaan Inc. (CAN) files $270M shelf registration, ADS = 15 shares

Rhea-AI Filing Summary

Canaan Inc. has filed a post-effective amendment to register an at-the-market shelf of securities permitting the offer and sale of up to $270,000,000 of Class A ordinary shares, preferred shares, warrants, debt securities, subscription rights, units and/or ADSs. Each ADS represents 15 Class A ordinary shares.

The prospectus states ADSs trade on NASDAQ under the symbol CAN and cites a last reported sale price of $0.44 per ADS on May 20, 2026. The filing discloses share counts “As of the date of this prospectus”: 11,237,922,873 Class A ordinary shares and 311,624,444 Class B ordinary shares issued and outstanding. The prospectus also highlights risks under the Holding Foreign Companies Accountable Act and PCAOB inspection access for auditors located in mainland China and Hong Kong.

Insights

Capital Markets Attorney

Registers a $270M shelf and confirms ATM mechanics and regulatory cautions.

The filing establishes a shelf registration permitting offerings up to $270,000,000 in multiple instruments, including ADSs (each representing 15 underlying Class A shares). The prospectus makes clear that specific terms will be provided in prospectus supplements and that offerings may occur "from time to time" and through underwriters, agents or directly.

The document preserves the operative qualifier that trading and certain distribution methods may be constrained by the HFCAA outcome and PCAOB inspection determinations; subsequent prospectus supplements and exchanges will provide the mechanics and pricing for any takedown.

Corporate Finance Analyst

Neutral financing flexibility: shelf and ATM capacity but no specific takedown disclosed here.

The shelf permits issuance of equity, ADSs, debt and hybrid instruments up to $270,000,000. The company previously used ATM programs and completed registered placements and conversions; the filing reiterates prior ATM capacity and historic draws (e.g., $7.2M net proceeds from 4,841,000 ADSs in 2025).

Whether the shelf materially affects capitalization depends on future supplements that state offering sizes, pricing and whether proceeds accrue to the issuer; the prospectus notes proceeds usage will be described in each prospectus supplement.

We may from time to time in one or more offerings offer and sell our preferred shares, warrants, subscription rights and/or units, debt securities, or Class A ordinary shares, including Class A ordinary shares represented by American depositary shares, or ADSs, with each ADS representing 15 Class A ordinary shares.

We will provide specific terms of any offered securities and offering in a supplement to this prospectus. Any prospectus supplement may also add, update, or change information contained in this prospectus. You should carefully read this prospectus and the applicable prospectus supplement as well as the documents incorporated or deemed to be incorporated by reference in this prospectus before you purchase any of the securities offered hereby.

These securities may be offered and sold in the same offering or in separate offerings; to or through underwriters, dealers, and agents; or directly to purchasers. The names of any underwriters, dealers, or agents involved in the sale of our securities, their compensation and any over-allotment options held by them will be described in the applicable prospectus supplement. For a more complete description of the plan of distribution of these securities, see the section entitled “Plan of Distribution” beginning on page 52 of this prospectus.

The ADSs are listed on the NASDAQ Global Market under the symbol “CAN.” On May 20, 2026, the last reported sale price of the ADSs on the NASDAQ Global Market was US$0.44 per ADS.

As of the date of this prospectus, our issued and outstanding share capital consists of Class A ordinary shares and Class B ordinary shares. Holders of Class A ordinary shares and Class B ordinary shares have the same rights except for voting and conversion rights. In respect of matters requiring a shareholder vote, each Class A ordinary share will be entitled to one vote and each Class B ordinary share will be entitled to 15 votes. Each Class B ordinary share is convertible into one class A ordinary share at any time by the holder thereof. Class A ordinary shares are not convertible into Class B ordinary shares under any circumstances. For more information, please see “Description of Share Capital.”

We are a Cayman Islands holding company and conduct all of our operations through our operating subsidiaries. Investors in the ADSs are not purchasing equity securities of our operating subsidiaries but instead are purchasing equity securities of a Cayman Islands holding company. We face various legal and operational risks and uncertainties associated with being based in or having a portion of our operations in China and the complex and evolving PRC laws and regulations. For example, we face risks associated with regulatory approvals on offerings conducted overseas and foreign investment in China-based issuers, anti-monopoly regulatory actions, regulatory actions for virtual currency-related business activities and mining activities and oversight on cybersecurity and data privacy, which may negatively impact our ability to conduct certain businesses, access foreign investments, or list on foreign stock exchange. These risks could result in a material adverse change in our operations and the value of our ADSs, significantly limit or completely hinder our ability to offer or continue to offer securities to investors, or cause the value of such securities to significantly decline or become worthless. For a detailed description of risks relating to doing business in China, see “Item 3. Key Information — 3.D. Risk Factors — Risks Relating to Doing Business in the PRC.” in our annual report on Form 20-F for the year ended December 31, 2025, which is incorporated by reference in this prospectus.

Our auditor, KPMG Huazhen LLP, is the independent registered public accounting firm that issues the audit report incorporated by reference elsewhere in this prospectus, and is located in mainland China. Our securities will be prohibited from trading on a national securities exchange or in the over-the-counter trading market in the United States under the Holding Foreign Companies Accountable Act, or the HFCAA, if the Securities and Exchange Commission determines that Canaan has filed audit reports issued by a registered public accounting firm that has not been subject to inspections by the PCAOB for two consecutive years. On December 16, 2021, the PCAOB issued a report to notify the SEC of its determination that the PCAOB was unable to inspect or investigate completely registered public accounting firms headquartered in mainland China and Hong Kong and our auditor was subject to this determination. Consequently, we were conclusively identified as a “Commission-Identified Issuer” on May 4, 2022. On December 15, 2022, the PCAOB announced that it was able to secure complete access to inspect and investigate PCAOB-registered public accounting firms headquartered in mainland China and Hong Kong in 2022. Each year, the PCAOB will determine whether it can inspect and investigate completely audit firms in mainland China and Hong Kong, among other jurisdictions. If the PCAOB determines in the future that it no longer has full access to inspect and investigate completely accounting firms in mainland China and Hong Kong and we use an accounting firm headquartered in one of these jurisdictions to issue an audit report on its financial statements filed with the SEC, we would be identified as a Commission-Identified Issuer following the filing of the annual report on Form 20-F for the relevant fiscal year. In accordance with the HFCAA, our securities would be prohibited from being traded on a national securities exchange or in the over-the-counter trading market in the United States if it is identified as a Commission- Identified Issuer for two consecutive years in the future. If our securities are prohibited from trading in the United States, there is no certainty that we will be able to list on a non-U.S. exchange or that a market for our securities will develop outside of the United States. In the event of such prohibition, the Nasdaq may determine to delist our securities. The delisting of our securities, or the threat of their being delisted, may materially and adversely affect the value of your investment. See “Item 3. Key Information — 3.D. Risk Factors — Risks Relating to Doing Business in the PRC — Our ADSs may be delisted under the Holding Foreign Companies Accountable Act if the PCAOB is unable to inspect auditors who are located in China. The delisting of our ADSs, or the threat of their being delisted, may materially and adversely affect the value of your investment.” in our annual report on Form 20-F for the year ended December 31, 2025, which is incorporated by reference in this prospectus.

Investing in these securities involves risks. See the “Risk Factors” section contained in the applicable prospectus supplement and the documents we incorporate by reference in this prospectus to read about factors you should consider before investing in our securities.

This prospectus may not be used to offer or sell any securities unless accompanied by a prospectus supplement.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of securities or passed upon the accuracy or adequacy of the disclosures in this prospectus, including any prospectus supplement and documents incorporated by reference. Any representation to the contrary is a criminal offense.

OUR COMPANY

We primarily focus on providing crypto mining solutions through our proprietary ASICs. We have strong ASIC chip design capability underpinned by over ten years of industry experience and the expertise of our founders and management team. We are one of the few fabless IC design companies with the advanced technology to independently design ASIC, established access to leading wafer foundry capacity and proven in-house capability to produce Bitcoin mining machines. We primarily dedicated technology and expertise in ASIC applications to industrial Bitcoin mining machines and are a leading producer of Bitcoin mining machines in the global market. In addition, to further diversify our product offering and democratize access to bitcoin mining, we launched the Avalon Home series in 2024 and formally commercialized it in 2025, a new line of compact, energy-efficient mining devices crafted for individual users and home environments. The Avalon Home series represents our first step into the home-use mining machine market, blending reliable hash rate output with user-friendly interfaces, low noise operation, and streamlined connectivity. We believe our extensive experience and expertise in ASIC applications position us well in our future endeavors.

Leveraging our deep understanding of the cryptocurrency industry and strong technology as applied to ASIC chip design, we intend to capture the growth opportunity along the value chain of the cryptocurrency industry to enhance our offerings and achieve more stable financial performance. We have started with the Bitcoin mining business through our strategic collaboration with certain cryptocurrency mining farms and energy providers, aiming to develop the Bitcoin mining business as the second engine to capitalize on the Bitcoin ecosystem and synergize with our bitcoin mining machines sales. We also intend to engage in Bitcoin mining through self-owned facilities. We endeavor to grow our deployed computing power for mining and improve the energized hash rate to enhance our mining business. For the years ended December 31, 2023, 2024 and 2025, we generated revenue of US$34.0 million, US$44.0 million and US$113.2 million from the Bitcoin mining business, respectively.

We have developed competitive advantages in our business and technological capabilities, including the following:

•

Our expertise in the development, designing and production of Bitcoin mining machines;

​

•

Our mastery of the whole IC design process;

​

•

Our years of accumulated engineering experience in applying theoretical research to the mass production of new products;

​

•

Our ability to achieve a fast time-to-market with our products and our successful early monetization of the ASIC design in blockchain applications have provided us with an early advantage with respect to both technology and capital reserve to pursue our strategic initiatives;

​

•

Our breakthroughs in various technological fields to improve ASIC performance, such as low voltage and high power efficiency operations and high computing density, all of which are crucial features for ASICs for blockchain;

​

•

Our ownership of most of the intellectual property we employ, and our accumulation of valuable know-how and multiple generations of proprietary silicon data through our long-term ASIC design experience;

​

•

Our long-term partnerships with leading global suppliers, which have enabled us to achieve high-quality, high yield rate and stable production;

​

•

Our continued development of the penetration into the Bitcoin mining business by leveraging our experience in Bitcoin mining machines production and sales, as well as our relationship with global mining farms; and

TABLE OF CONTENTS​

DESCRIPTION OF SHARE CAPITAL

We are an exempted company incorporated in the Cayman Islands with limited liability and our affairs are governed by our memorandum and articles of association, and the Companies Act of the Cayman Islands, as amended, which we refer to as the Cayman Companies Act, and the common law of the Cayman Islands.

As of the date of this prospectus, our authorized share capital was US$50,000 divided into 999,643,050,556 Class A ordinary shares of per value US$0.00000005 each and 356,624,444 Class B ordinary shares of par value US$0.00000005 each, 125,000 Series A Preferred Shares of par value US$0.00000005 each, and 200,000 Series A-1 Preferred Shares of par value US$0.00000005 each.

As of the date of this prospectus, we have 11,237,922,873 Class A ordinary shares, 311,624,444 Class B ordinary shares issued and outstanding. As of the date of this prospectus, there are no issued and outstanding preferred shares.

The following are summaries of certain material provisions of our amended and restated memorandum and articles of association adopted by special resolution passed on October 8, 2019 and effective immediately prior to the completion of the initial public offering of our ADSs representing our Class A ordinary shares, or our articles of association and the Cayman Companies Act insofar as they relate to the material terms of our ordinary shares. The following summary is not complete, and you should read our amended and restated memorandum and articles of association, a form of which was filed with the SEC as Exhibit 3.2 to the registration statement on Form F-1 (File No. 333-234356), originally filed on October 28, 2019, as amended.

Ordinary Shares

General

All of our issued and outstanding ordinary shares are fully paid and non-assessable. Our ordinary shares are divided into Class A ordinary shares and Class B ordinary shares. Holders of our Class A ordinary shares and Class B ordinary shares will have the same rights except for voting and conversion rights. Each Class A Ordinary Share shall entitle the holder thereof to one vote on all matters subject to vote at our general meetings, and each Class B ordinary share shall entitle the holder thereof to 15 votes on all matters subject to vote at our general meetings. Our ordinary shares are issued in registered form, and are issued when registered in our register of shareholders. Our shareholders who are non-residents of the Cayman Islands may freely hold and vote their ordinary shares. We may not issue shares to bearer.

Conversion

Each Class B ordinary share is convertible into one Class A ordinary share at any time at the option of the holder thereof. Class A ordinary shares are not convertible into Class B ordinary shares under any circumstances. Pursuant to our articles of association, upon any sale, transfer, assignment or disposition of any Class B ordinary share by a holder thereof to any person who is not an affiliate of such holder, or upon a change of ultimate beneficial ownership of any Class B ordinary share to any person who is not an affiliate of the registered shareholder of such Class B ordinary share, such Class B ordinary share shall be automatically and immediately converted into the same number of Class A ordinary share. For this purpose, beneficial ownership shall have the meaning set forth in Rule 13d-3 under the United States Securities Exchange Act of 1934, as amended.

An “affiliate” for the purposes of our articles of association means in respect of a person, any other person that, directly or indirectly, through one or more intermediaries, controls, is controlled by, or is under common control with, such person, and (i) in the case of a natural person, shall include, without limitation, such person’s spouse, parents, children, siblings, mother-in-law, father-in-law, brothers-in-law and sisters-in-law, a trust for the benefit of any of the foregoing, and a corporation, partnership or any other entity wholly or jointly owned by any of the foregoing, and (ii) in the case of an entity, shall include a partnership, a corporation or any other entity or any natural person which directly, or indirectly through one or more intermediaries, controls, is controlled by, or is under common control with, such entity.

having such power only by reason of the happening of a contingency), or having the power to control the management or elect a majority of members to the board of directors or equivalent decision-making body of such corporation, partnership or other entity.

A “person” for the purposes of our articles of association means any natural person, firm, company, joint venture, partnership, corporation, association or other entity (whether or not having a separate legal personality) or any of them as the context so requires.

For the avoidance of doubt, on the transmission of shares following the death of a holder of Class B ordinary shares, such Class B ordinary shares will not automatically convert into the same number of Class A ordinary shares unless such transmission of shares results in a change in ultimate beneficial ownership of such Class B ordinary share(s) to any person who is not an affiliate of the relevant holder of Class B ordinary shares.

Dividends

The holders of our ordinary shares are entitled to such dividends as may be declared by our board of directors. In addition, our shareholders may declare dividends by ordinary resolution, but no dividend shall exceed the amount recommended by our directors. Under the laws of the Cayman Islands, our company may pay a dividend out of either profit or share premium account, provided that in no circumstances may a dividend be paid if this would result in our company being unable to pay its debts as they fall due in the ordinary course of business.

Voting Rights

Our ordinary shares consist of Class A ordinary shares and Class B ordinary shares. Holders of our Class A ordinary shares and our Class B ordinary shares shall, at all times, vote together as one class on all matters submitted to a vote by our shareholders at any general meeting of our company. Each Class A ordinary share shall be entitled to one vote, and each Class B ordinary share shall be entitled to 15 votes, on all matters subject to a vote at general meetings of our company.

Voting at any meeting of shareholders is by a show of hands, unless a poll is (before or on the declaration of the result of the show of hands) demanded by the chairman of the meeting or any shareholder present in person or by proxy of the Company entitled to vote, and, unless a poll is so demanded, a declaration by the chairman of the meeting that a resolution has, on a show of hands, been carried or carried unanimously, or by a particular majority, or lost and an entry to that effect in the minutes of the proceedings of the Company, shall be conclusive evidence of the fact, without proof of the number of proportion of the votes recorded in favor of, or against that resolution.

Transfer of Shares

Any of our shareholders may transfer all or any of his or her ordinary shares by an instrument of transfer in any usual or common form or any other form approved by our board of directors, executed by or on behalf of the transferor.

Our board of directors may, in its absolute discretion, decline to register any transfer of any ordinary share that has not been fully paid up or is subject to a company lien. Our board of directors may also decline to register any transfer of any ordinary share unless:

•

the instrument of transfer is lodged with us, accompanied by the certificate for the ordinary shares to which it relates and such other evidence as our board of directors may reasonably require to show the right of the transferor to make the transfer;

​

•

the instrument of transfer is in respect of only one class of ordinary shares;

​

•

the instrument of transfer is properly stamped, if required;

​

•

the ordinary share transferred is fully paid and free of any lien in favor of us;

​

•

any fee related to the transfer has been paid to us; and in the case of any transfer to joint holders, the transfer is not to more than four joint holders.

Winding Up

On the winding up of our company, if the assets available for distribution amongst our shareholders shall be more than sufficient to repay the whole of the share capital at the commencement of the winding up, the surplus shall be distributed amongst our shareholders in proportion to the par value of the shares held by them at the commencement of the winding up, subject to a deduction from those shares in respect of which there are monies due, of all monies payable to our company for unpaid calls or otherwise. If our assets available for distribution are insufficient to repay the whole of the share capital, such assets will be distributed so that, as nearly as may be, the losses are borne by our shareholders in proportion to the par value of the shares held by them.

The liquidator may, with the sanction of a special resolution of our shareholders, divide amongst the shareholders in species or in kind the whole or any part of the assets of our company, and may for such purpose set such value as the liquidator deems fair upon any property to be divided as aforesaid and may determine how the division shall be carried out as between our shareholders or different classes of shareholders.

We are an exempted company with limited liability incorporated under the Cayman Companies Act, and under the Cayman Companies Act, the liability of our shareholders is limited to the amount, if any, unpaid on the shares respectively held by them. Our memorandum of association contains a declaration that the liability of our members is so limited.

Redemption, Repurchase and Surrender of Ordinary Shares

We may issue shares on terms that such shares are subject to redemption, at our option or at the option of the holders thereof, on such terms and in such manner as may be determined, before the issue of such shares, by our board of directors or by our shareholders by special resolution. Our company may also repurchase any of our shares (including any redeemable shares) in such manner and terms as been approved by our board of directors or by ordinary resolution of our shareholders, or as otherwise authorized by our articles of association. Under the Cayman Companies Act, the redemption or repurchase of any share may be paid out of our company’s profits or out of the proceeds of a new issue of shares made for the purpose of such redemption or repurchase, or out of capital (including share premium account and capital redemption reserve) if our company can, immediately following such payment, pay its debts as they fall due in the ordinary course of business. In addition, under the Cayman Companies Act no such share may be redeemed or repurchased (a) unless it is fully paid up, (b) if such redemption or repurchase would result in there being no shares outstanding or (c) if the company has commenced liquidation. In addition, our company may accept the surrender of any fully paid share for no consideration.

Calls on Ordinary Shares and Forfeiture of Ordinary Shares

Our board of directors may from time to time make calls upon shareholders (or any of them) for any amounts unpaid on their ordinary shares in a notice served to such shareholders at least 14 calendar days prior to the specified time and place of payment. The ordinary shares that have been called upon and remain unpaid are subject to forfeiture.

General Meetings of Shareholders

As a Cayman Islands exempted company, we are not obliged by the Cayman Companies Act to call shareholders’ annual general meetings. Our articles of association provide that we may (but are not obliged to) in each year hold a general meeting as our annual general meeting in which case we shall specify the meeting as such in the notices calling it, and the annual general meeting shall be held at such time and place as may be determined by our directors.

Shareholders’ general meetings may be convened by a majority of our board of directors or by our chairman. Advance notice of at least ten calendar days is required for the convening of our annual general shareholders’ meeting (if any) and any other general meeting of our shareholders. A quorum required for any general meeting of shareholders consists of at least one shareholder present or by proxy, representing not less than one-third of all votes attaching to the total issued voting shares in our company.

TABLE OF CONTENTS

The Cayman Companies Act provides shareholders with only limited rights to requisition a general meeting, and does not provide shareholders with any right to put any proposal before a general meeting. However, these rights may be provided in a company’s articles of association. Our articles of association provide that upon the requisition of shareholders representing in aggregate not less than one-third of the votes attaching to the issued and outstanding shares of our company entitled to vote at general meetings, our board will convene an extraordinary general meeting and put the resolutions so requisitioned to a vote at such meeting. However, our articles of association do not provide our shareholders with any right to put any proposals before annual general meetings or extraordinary general meetings not called by such shareholders.

Proceedings of Board of Directors

Our articles of association provide that subject to the Cayman Companies Act, our articles of association and to any resolutions passed in a general meeting of our company, our business is to be managed and conducted by our board of directors. The quorum necessary for board meetings may be fixed by the board and, unless so fixed at another number, will be a majority of the directors.

Our articles of association provide that the board may from time to time at its discretion exercise all powers of our company to raise capital or borrow money, to mortgage or charge all or any part of the undertaking, property and assets (present and future) and uncalled capital of our company and issue debentures, bonds and other securities of our company, whether outright or as collateral security for any debt, liability or obligation of our company or of any third party.

Changes in Capital

Our shareholders may from time to time by ordinary resolution:

•

increase our share capital by such sum, to be divided into shares of such classes and amount, as the resolution shall prescribe;

​

•

consolidate and divide all or any of our share capital into shares of a larger amount than our existing shares;

​

•

sub-divide our existing shares, or any of them, into shares of a smaller amount; or

​

•

cancel any shares which, at the date of the passing of the resolution, have not been taken or agreed to be taken by any person and diminish the amount of our share capital by the amount of the shares so canceled.

​

Our shareholders may by special resolution, subject to confirmation by the Grand Court of the Cayman Islands on an application by our company for an order confirming such reduction, reduce our share capital or any capital redemption reserve in any manner permitted by law.

Inspection of Books and Records

Holders of our ordinary shares will have no general right under the Cayman Companies Act to inspect or obtain copies of our list of shareholders or our corporate records (except for our memorandum and articles of association, special resolutions of our shareholders and our register of mortgages and charges). Under Cayman Islands law, the names of our current directors can be obtained from a search conducted at the Registrar of Companies in the Cayman Islands. However, we will provide our shareholders with annual audited financial statements. See “Where You Can Find More Information.”

Exempted Company

We are an exempted company with limited liability duly incorporated and validly existing under the Cayman Companies Act. The Cayman Companies Act distinguishes between ordinary resident companies and exempted companies. Any company that is registered in the Cayman Islands but conducts business mainly outside of the Cayman Islands may apply to be registered as an exempted company. The requirements for an exempted company are essentially the same as for an ordinary company except for the exemptions and privileges listed below:

10

TABLE OF CONTENTS

•

an exempted company does not have to file an annual return of its shareholders with the Registrar of Companies of the Cayman Islands;

​

•

an exempted company’s register of members is not open to inspection;

​

•

an exempted company does not have to hold an annual general meeting;

​

•

an exempted company may issue no par value shares;

​

•

an exempted company may obtain an undertaking against the imposition of any future taxation (such undertakings are given for up to 30 years);

​

•

an exempted company may register by way of continuation in another jurisdiction and be deregistered in the Cayman Islands;

​

•

an exempted company may register as a limited duration company; and

​

•

an exempted company may register as a segregated portfolio company.

​

“Limited liability” means that the liability of each shareholder is limited to the amount unpaid by the shareholder on that shareholder’s shares of the company (except in exceptional circumstances, such as involving fraud, the establishment of an agency relationship or an illegal or improper purpose or other circumstances in which a court may be prepared to pierce or lift the corporate veil). Upon the closing of this offering, we will be subject to reporting and other informational requirements of the Exchange Act, as applicable to foreign private issuers. We may follow the home country practice for certain corporate governance practices after the closing of this offering which may differ from the Nasdaq Stock Market Rules. The Nasdaq Stock Market Rules require that every company listed on the Nasdaq Global Market hold an annual general meeting of shareholders. In addition, our articles of association allow our directors to call extraordinary general meetings of our shareholders pursuant to the procedures set forth in our articles of association.

Differences in Corporate Law

The Cayman Companies Act is derived, to a large extent, from the older Companies Acts of England, but does not follow recent statutory enactments in England and accordingly there are significant differences between the Cayman Companies Act and the current Companies Act of England. In addition, the Cayman Companies Act differs from laws applicable to United States corporations and their shareholders. Set forth below is a summary of certain significant differences between the provisions of the Cayman Companies Act applicable to us and the laws applicable to companies incorporated in the State of Delaware.

Mergers and Similar Arrangements

The Cayman Companies Act permits mergers and consolidations between the Cayman Islands companies and between the Cayman Islands companies and the non-Cayman Islands companies. For these purposes, (a) “merger” means the merging of two or more constituent companies and the vesting of their undertaking, property and liabilities in one of such companies as the surviving company, and (b) a “consolidation” means the combination of two or more constituent companies into a consolidated company and the vesting of the undertaking, property and liabilities of such companies to the consolidated company. In order to effect such a merger or consolidation, the directors of each constituent company must approve a written plan of merger or consolidation, which must then be authorized by (a) a special resolution of the shareholders of each constituent company, and (b) such other authorization, if any, as may be specified in such constituent company’s articles of association. The plan must be filed with the Registrar of Companies of the Cayman Islands together with, among other things, a declaration as to the solvency of the consolidated or surviving company, a list of the assets and liabilities of each constituent company and an undertaking that a copy of the certificate of merger or consolidation will be given to the members and creditors of each constituent company and that notification of the merger or consolidation will be published in the Cayman Islands Gazette. Court approval is not required for a merger or consolidation which is effected in compliance with these statutory procedures.

11

TABLE OF CONTENTS

A merger between a Cayman parent company and its Cayman subsidiary or subsidiaries does not require authorization by a resolution of shareholders of that Cayman subsidiary if a copy of the plan of merger is given to every member of that Cayman subsidiary to be merged unless that member agrees otherwise. For this purpose, a company is a “parent” of a subsidiary if it holds issued shares that together represent at least ninety percent (90%) of the votes at a general meeting of the subsidiary.

The consent of each holder of a fixed or floating security interest of a constituent company is required unless this requirement is waived by a court in the Cayman Islands.

Except in certain limited circumstances, a shareholder of a Cayman Islands constituent company who dissents from the merger or consolidation is entitled to payment of the fair value of his or her shares (which, if not agreed between the parties, will be determined by the Cayman Islands court) upon dissenting from a merger or consolidation, provided the dissenting shareholder complies strictly with the procedures set out in the Cayman Companies Act. The exercise of such dissenter rights will preclude the exercise by the dissenting shareholder of any other rights to which he or she might otherwise be entitled by virtue of holding shares, except for the right to seek relief on the grounds that the merger or consolidation is void or unlawful.

Separate from the statutory provisions relating to mergers and consolidations, the Cayman Companies Act also contain statutory provisions that facilitate the reconstruction and amalgamation of companies by way of schemes of arrangement, provided that the arrangement is approved by (a) 75% in value of the shareholders or class of shareholders, as the case may be, or (b) a majority in number representing 75% in value of the creditors or each class of creditors, as the case may be, with whom the arrangement is to be made, that are, in each case, present and voting either in person or by proxy at a meeting, or meetings, convened for that purpose. The convening of the meeting or meetings and subsequently the arrangement must be sanctioned by the Grand Court of the Cayman Islands. While a dissenting shareholder has the right to express to the court the view that the transaction ought not to be approved, the court can be expected to approve the arrangement if it determines that:

•

the statutory provisions as to the required majority vote have been met;

​

•

the shareholders have been fairly represented at the meeting in question and the statutory majority are acting bona fide without coercion of the minority to promote interests adverse to those of the class;

​

•

the arrangement is such that may be reasonably approved by an intelligent and honest man of that class acting in respect of his interest; and

​

•

the arrangement is not one that would more properly be sanctioned under some other provision of the Cayman Companies Act.

​

The Cayman Companies Act also contains a statutory power of compulsory acquisition which may facilitate the “squeeze out” of dissenting minority shareholder upon a tender offer. When a tender offer is made and accepted by holders of 90% of the shares affected within four months of the offer being made, the offeror may, within a two-month period commencing on the expiration of such four-month period, require the holders of the remaining shares to transfer such shares to the offeror on the terms of the offer. An objection can be made to the Grand Court of the Cayman Islands but this is unlikely to succeed in the case of an offer which has been so approved unless there is evidence of fraud, bad faith or collusion.

If an arrangement and reconstruction by the way of scheme of arrangement is thus approved, or if a tender offer is made and accepted in accordance with the foregoing statutory procedures, a dissenting shareholder would have no rights comparable to appraisal rights, save that objectors to a takeover offer may apply to the Grand Court of the Cayman Islands for various orders that the Grand Court of the Cayman Islands has a broad discretion to make, which would otherwise ordinarily be available to dissenting shareholders of Delaware corporations, providing rights to receive payment in cash for the judicially determined value of the shares.

Shareholders’ Suits

In principle, we will normally be the proper plaintiff to sue for a wrong done to us as a company and as a general rule, a derivative action may not be brought by a minority shareholder. However, based on English law authorities, which would in all likelihood be of persuasive authority in the Cayman Islands, the Cayman

12

TABLE OF CONTENTS

Islands court can be expected to follow and apply the common law principles (namely the rule in Foss v. Harbottle and the exceptions thereto) so that a non-controlling shareholder may be permitted to commence a class action against or derivative actions in the name of the company to challenge:

•

an act which is illegal or ultra vires with respect to the company and is therefore incapable of ratification by the shareholders;

​

•

an act which, although not ultra vires, requires authorization by a qualified (or special) majority (that is, more than a simple majority) which has not been obtained; and

​

•

an act which constitutes a “fraud on the minority” where the wrongdoers are themselves in control of the company.

​

Indemnification of Directors and Executive Officers and Limitation of Liability

The Cayman Companies Act does not limit the extent to which a company’s memorandum and articles of association may provide for indemnification of officers and directors, except to the extent any such provision may be held by the Cayman Islands courts to be contrary to public policy, such as to provide indemnification against dishonesty, willful default or fraud or the consequences of committing a crime. Our articles of association provide that we shall indemnify our officers and directors against all actions, proceedings, costs, charges, expenses, losses, damages or liabilities incurred or sustained by such directors or officer, other than by reason of such person’s dishonesty, willful default or fraud, in or about the conduct of our company’s business or affairs (including as a result of any mistake of judgment) or in the execution or discharge of his duties, powers, authorities or discretions, including without prejudice to the generality of the foregoing, any costs, expenses, losses or liabilities incurred by such director or officer in defending (whether successfully or otherwise) any civil proceedings concerning our company or its affairs in any court whether in the Cayman Islands or elsewhere. This standard of conduct is generally the same as permitted under the Delaware General Corporation Law for a Delaware corporation. In addition, we intend to enter into indemnification agreements with our directors and executive officers that will provide such persons with additional indemnification beyond that provided in our articles of association.

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

Anti-Takeover Provisions in Our Articles

Some provisions of our articles of association may discourage, delay or prevent a change in control of our company or management that shareholders may consider favorable, including provisions that authorize our board of directors to issue preferred shares in one or more series and to designate the price, rights, preferences, privileges and restrictions of such preferred shares without any further vote or action by our shareholders.

However, under the Cayman Islands law, our directors may only exercise the rights and powers granted to them under our articles of association, as amended and restated from time to time, for a proper purpose and in what they believe in good faith to be in the best interests of our company.

Directors’ Fiduciary Duties

Under Delaware corporate law, a director of a Delaware corporation has a fiduciary duty to the corporation and its shareholders. This duty has two components: the duty of care and the duty of loyalty. The duty of care requires that a director acts in good faith, with the care that an ordinarily prudent person would exercise under similar circumstances. Under this duty, a director must inform himself of, and disclose to shareholders, all material information reasonably available regarding a significant transaction. The duty of loyalty requires that a director acts in a manner he or she reasonably believes to be in the best interests of the corporation. He or she must not use his or her corporate position for personal gain or advantage. This duty prohibits self-dealing by a director and mandates that the best interests of the corporation and its shareholders take precedence over any interest possessed by a director, officer or controlling shareholder and not shared by

13

TABLE OF CONTENTS

the shareholders generally. In general, actions of a director are presumed to have been made on an informed basis, in good faith and in the honest belief that the action taken was in the best interests of the corporation. However, this presumption may be rebutted by evidence of a breach of one of the fiduciary duties. Should such evidence be presented concerning a transaction by a director, a director must prove the procedural fairness of the transaction, and that the transaction was of fair value to the corporation.

As a matter of Cayman Islands law, a director of a Cayman Islands company is in the position of a fiduciary with respect to the company and therefore it is considered that he owes the following duties to the company — a duty to act bona fide in good faith in the best interests of the company, a duty not to make a personal profit based on his or her position as director (unless the company permits him to do so), a duty not to put himself in a position where the interests of the company conflict with his or her personal interest or his or her duty to a third party, and a duty to exercise powers for the purpose for which such powers were intended. A director of a Cayman Islands company owes to the company a duty to act with skill and care. It was previously considered that a director need not exhibit in the performance of his or her duties a greater degree of skill than may reasonably be expected from a person of his or her knowledge and experience. However, English and Commonwealth courts have moved towards an objective standard with regard to the required skill and care and these authorities are likely to be followed in the Cayman Islands.

Shareholder Proposals

Under the Delaware General Corporation Law, a shareholder has the right to put any proposal before the annual meeting of shareholders, provided it complies with the notice provisions in the governing documents. The Delaware General Corporation Law does not provide shareholders an express right to put any proposal before the annual meeting of shareholders, but in keeping with common law, Delaware corporations generally afford shareholders an opportunity to make proposals and nominations provided that they comply with the notice provisions in the certificate of incorporation or bylaws. A special meeting may be called by the board of directors or any other person authorized to do so in the governing documents, but shareholders may be precluded from calling special meetings.

The Cayman Companies Act provides shareholders with only limited rights to requisition a general meeting, and does not provide shareholders with any right to put any proposal before a general meeting. However, these rights may be provided in a company’s articles of association. Our articles of association allow our shareholders holding in aggregate not less than one-third of the votes attaching to the issued and outstanding shares of our company entitled to vote at general meetings to requisition an extraordinary general meeting of our shareholders, in which case our board is obliged to convene an extraordinary general meeting and to put the resolutions so requisitioned to a vote at such meeting. Our articles of association provide no other right to put any proposals before annual general meetings or extraordinary general meetings. As a Cayman Islands exempted company, we are not obligated by law to call shareholders’ annual general meetings.

Cumulative Voting

Under the Delaware General Corporation Law, cumulative voting for elections of directors is not permitted unless the corporation’s certificate of incorporation specifically provides for it. Cumulative voting potentially facilitates the representation of minority shareholders on a board of directors since it permits the minority shareholder to cast all the votes to which the shareholder is entitled on a single director, which increases the shareholder’s voting power with respect to electing such director. The Cayman Islands law does not prohibit cumulative voting, but our articles of association do not provide for cumulative voting. As a result, our shareholders are not afforded any fewer protections or rights on this issue than shareholders of a Delaware corporation.

Removal of Directors

Under the Delaware General Corporation Law, a director of a corporation with a classified board may be removed only for cause with the approval of a majority of the outstanding shares entitled to vote, unless the certificate of incorporation provides otherwise. Under our articles of association, directors may be removed by ordinary resolution of our shareholders. An appointment of a director may be on terms that the director shall automatically retire from office (unless he has sooner vacated office) at the next or a subsequent annual general meeting or upon any specified event or after any specified period in a written agreement between the

14

TABLE OF CONTENTS

company and the director, if any; but no such term shall be implied in the absence of express provision. In addition, a director’s office shall be vacated if the director (i) becomes bankrupt or makes any arrangement or composition with his creditors; (ii) dies or is found to be or becomes of unsound mind; (iii) resigns his office by notice in writing to the company; (iv) without special leave of absence from our board of directors, is absent from three consecutive meetings of the board and the board resolves that his office be vacated or; (v) is removed from office pursuant to any other provisions of our articles of association.

Transactions with Interested Shareholders

The Delaware General Corporation Law contains a business combination statute applicable to Delaware public corporations whereby, unless the corporation has specifically elected not to be governed by such statute by amendment to its certificate of incorporation or bylaws that is approved by its shareholders, it is prohibited from engaging in certain business combinations with an “interested shareholder” for three years following the date that such person becomes an interested shareholder. An interested shareholder generally is a person or a group who or which owns or owned 15% or more of the target’s outstanding voting stock or who or which is an affiliate or associate of the corporation and owned 15% or more of the corporation’s outstanding voting stock within the past three years. This has the effect of limiting the ability of a potential acquirer to make a two-tiered bid for the target in which all shareholders would not be treated equally. The statute does not apply if, among other things, prior to the date on which such shareholder becomes an interested shareholder, the board of directors approves either the business combination or the transaction which resulted in the person becoming an interested shareholder. This encourages any potential acquirer of a Delaware corporation to negotiate the terms of any acquisition transaction with the target’s board of directors.

The Cayman Islands law has no comparable statute. As a result, we cannot avail ourselves of the types of protections afforded by the Delaware business combination statute. However, although Cayman Islands law does not regulate transactions between a company and its significant shareholders, the fiduciary duties owed by our directors do require that such transactions must be entered into bona fide in the best interests of the company and for a proper corporate purpose and not with the effect of constituting a fraud on the minority shareholders.

Restructuring.

A company may present a petition to the Grand Court of the Cayman Islands for the appointment of a restructuring officer on the grounds that the company:

(a)

is or is likely to become unable to pay its debts; and

​

(b)

intends to present a compromise or arrangement to its creditors (or classes thereof) either pursuant to the Companies Act, the law of a foreign country or by way of a consensual restructuring.

​

The Grand Court may, among other things, make an order appointing a restructuring officer upon hearing of such petition, with such powers and to carry out such functions as the court may order. At any time (i) after the presentation of a petition for the appointment of a restructuring officer but before an order for the appointment of a restructuring officer has been made, and (ii) when an order for the appointment of a restructuring officer is made, until such order has been discharged, no suit, action or other proceedings (other than criminal proceedings) shall be proceeded with or commenced against the company, no resolution to wind up the company shall be passed, and no winding up petition may be presented against the company, except with the leave of the court. However, notwithstanding the presentation of a petition for the appointment of a restructuring officer or the appointment of a restructuring officer, a creditor who has security over the whole or part of the assets of the company is entitled to enforce the security without the leave of the court and without reference to the restructuring officer appointed.

Dissolution; Winding Up

Under the Delaware General Corporation Law, unless the board of directors approves the proposal to dissolve, dissolution must be approved by shareholders holding 100% of the total voting power of the corporation. Only if the dissolution is initiated by the board of directors may it be approved by a simple

15

TABLE OF CONTENTS

majority of the corporation’s outstanding shares. Delaware law allows a Delaware corporation to include in its certificate of incorporation a supermajority voting requirement in connection with dissolutions initiated by the board of directors.

Under the Cayman Companies Act, our company may be wound up by either a special resolution of our shareholders or, if our company is unable to pay its debts as they fall due, by an ordinary resolution of our shareholders. In addition, a company may be wound up by an order of the courts of the Cayman Islands. The court has authority to order winding up in a number of specified circumstances including where it is, in the opinion of the court, just and equitable to do so.

Variation of Rights of Shares

Under the Delaware General Corporation Law, a corporation may vary the rights of a class of shares with the approval of a majority of the outstanding shares of such class, unless the certificate of incorporation provides otherwise. Under our articles of association, if our share capital is divided into more than one class of shares, we may materially and adversely vary the rights attached to any class only with the consent in writing of the holders of not less than two-thirds of the issued shares of that class or with the sanction of an ordinary resolution passed at a separate meeting of the holders of the shares of that class.

Amendment of Governing Documents

Under the Delaware General Corporation Law, a corporation’s certificate of incorporation may be amended only if adopted and declared advisable by the board of directors and approved by a majority of the outstanding shares entitled to vote, and the bylaws may be amended with the approval of a majority of the outstanding shares entitled to vote and may, if so provided in the certificate of incorporation, also be amended by the board of directors. Under the Cayman Companies Act and our articles of association, our memorandum and articles of association may only be amended by special resolution of our shareholders.

Rights of Non-Resident or Foreign Shareholders

There are no limitations imposed by our articles of association on the rights of non-resident or foreign shareholders to hold or exercise voting rights on our shares. In addition, there are no provisions in our articles of association that require the Company to disclose shareholder ownership above any particular ownership threshold.

Directors’ Power to Issue Shares

Under our articles of association, our board of directors is empowered to issue or allot shares or grant options, restricted shares, RSUs, share appreciation rights, dividend equivalent rights, warrants and analogous equity-based rights with or without preferred, deferred, qualified or other special rights or restrictions. In particular, pursuant to our articles of association, our board of directors has the authority, without further action by the shareholders, to issue all or any part of our capital and to fix the designations, powers, preferences, privileges, and relative participating, optional or special rights and the qualifications, limitations or restrictions therefrom, including dividend rights, conversion rights, voting rights, terms of redemption and liquidation preferences, any or all of which may be greater than the rights of our ordinary shares.

History of Securities Issuances

The following is a summary of our securities issuances in the past three years.

Ordinary Shares, Series A Preferred Shares and Series A-1 Preferred Shares

On November 10, 2023, we entered into an at market issuance sales agreement with B. Riley Securities, Inc. as a sales agent. From November 10, 2023 to December 31, 2023, we utilized the agreement with B. Riley Securities, Inc. for fundraising and sold 31,347,044 ADSs with net proceeds of approximately US$61.2 million at an average price of US$1.99 per ADS.

On November 27, 2023, we entered into a securities purchase agreement with an institutional investor (the “Buyer”), pursuant to which we agreed to issue and sell to the Buyer up to 125,000 Series A Preferred

16

TABLE OF CONTENTS

Shares at the price of US$1,000.00 for each Series A Preferred Share (the “Series A Preferred Shares Financing”). The Series A Preferred Shares Financing was conducted in three tranches. The first tranche and second tranche of the Series A Preferred Shares Financing were closed on December 11, 2023 and January 22, 2024, raising total gross proceeds of US$25 million and US$50 million, respectively. On September 27, 2024, we closed the third and final tranche of the Series A Preferred Shares Financing, raising additional total gross proceeds of US$50 million. As of the date of this prospectus, all such shares have been converted into Class A ordinary shares and there are no issued and outstanding Series A Preferred Shares.

On November 19, 2024, the Company entered into a securities purchase agreement with the Buyer, pursuant to which the Company agreed to issue and sell to the Buyer 30,000 Series A-1 Convertible Preferred Shares (the “Series A-1 Preferred Shares”) at the price of US$1,000.00 for each Series A-1 Preferred Share. On November 25, 2024, we closed the Series A-1 preferred shares financing, raising total gross proceeds of US$30 million. All such shares have been converted into Class A ordinary shares. As of the date of this prospectus, there are no issued and outstanding Series A-1 Preferred Shares.

On December 23, 2024, we entered into a sales agreement (the “ATM Agreement”) with Macquarie Capital Limited, Keefe, Bruyette & Woods, Inc., China Renaissance Securities (Hong Kong) Limited, Compass Point Research & Trading, LLC, Craig-Hallum Capital Group LLC, Northland Securities, Inc., Rosenblatt Securities Inc., The Benchmark Company, LLC, and B.

We filed a new prospectus supplement dated December 23, 2024, setting up the new at-the-market equity offering program (the “ATM Program”), under which the Company may sell up to an aggregate of US$270 million of the ADSs, each representing fifteen Class A ordinary shares of the Company, through or to the sales agents.

On March 6, 2025, we entered into a Securities Purchase Agreement with an institutional investor, relating to the purchase of up to 200,000 Series A-1 Preferred Shares (the “2025 Series A-1 Preferred Shares”) at US$1,000.00 for each Series A-1 Preferred Share, providing with total gross proceeds of up to US$200 million. The first tranche closing of 2025 Series A-1 Preferred Shares was completed on March 10, 2025, where an initial US$100 million has been received. Effective April 30, 2025, the Buyer and we have mutually agreed to terminate the agreement with respect to the second tranche. All aforementioned 2025 Series A-1 Preferred Shares have been converted into Class A ordinary shares. All pre-delivery shares have been returned to us.

On October 24, 2025, we entered into an At-the-market offering agreement (the “2025 ATM Agreement”) with Macquarie Capital Limited, Keefe, Bruyette & Woods, Inc., China Renaissance Securities (Hong Kong) Limited, Compass Point Research & Trading, LLC, Northland Securities, Inc., Rosenblatt Securities Inc., The Benchmark Company, LLC, B. Riley Securities Inc. (“B. Riley”) and CLSA Limited as sales agents (the “sales agents”), pursuant to which we may issue up to US$270.0 million of the ADSs. For the year ended December 31, 2025, we issued 4,841,000 ADSs with net proceeds of US$7.2 million.

On November 3, 2025, we entered into a securities purchase agreement with certain institutional investors for a registered direct placement of approximately US$72.0 million of our ADS, each ADS representing 15 Class A ordinary shares of us, par value US$0.00000005 per share, or US$1.13 per ADS (the “November 2025 RDO”).

Share Repurchase Program

We announced a share repurchase program approved by our board of directors on May 27, 2025, under which we may repurchase up to US$30 million worth of our outstanding ADSs and/or Class A ordinary shares over a period of six months. On December 17, 2025, we announced the renewal of share repurchase program approved by our board of directors, under which we may repurchase up to US$30 million worth of our outstanding ADSs and/or Class A ordinary shares over a period of twelve months. The repurchases have been through various means, including open market transactions at prevailing market prices, privately negotiated transactions, block trades or any combination thereof. The repurchases have been, and will be, effected in compliance with Rule 10b5-1 and/or Rule 10b-18 under the Exchange Act, and our insider trading policy. The number of ADSs repurchased and the timing of repurchases depends on a number of factors, including, but not limited to, price, trading volume and general market conditions, along with our working capital requirements and general business conditions.

DESCRIPTION OF AMERICAN DEPOSITARY SHARES

American Depositary Receipts

JPMorgan Chase Bank, N.A. (“JPMorgan”), as depositary, will issue the ADSs that you will be entitled to receive in this offering. Each ADS will represent an ownership interest in a designated number of shares, currently fifteen, that we will deposit with the custodian, as agent of the depositary, under the deposit agreement among ourselves, the depositary, and all holders and beneficial owners from time to time of American depositary receipts issued thereunder.

The depositary’s office is located at 270 Park Avenue, Floor 8, New York, New York 10017.

The ADS-to-share ratio is subject to amendment as provided in the form of ADR (which may give rise to fees contemplated by the form of ADR). In the future, each ADS will also represent any securities, cash or other property deposited with the depositary but which they have not distributed directly to you.

A beneficial owner is any person or entity having a beneficial ownership interest in ADSs. A beneficial owner need not be the holder of the ADR evidencing such ADS. If a beneficial owner is not an ADR holder, it must rely on the holder of the ADR(s) evidencing such ADSs in order to assert any rights or receive any benefits under the deposit agreement. A beneficial owner shall only be able to exercise any right or receive any benefit under the deposit agreement solely through the holder of the ADR(s) evidencing the ADSs owned by such beneficial owner. The arrangements between a beneficial owner and the holder of the corresponding ADRs may affect the beneficial owner’s ability to exercise any rights it may have.

An ADR holder shall be deemed to have all requisite authority to act on behalf of any and all beneficial owners of the ADSs evidenced by the ADRs registered in such ADR holder’s name for all purposes under the deposit agreement and ADRs. The depositary’s only notification obligations under the deposit agreement and the ADRs is to registered ADR holders. Notice to an ADR holder shall be deemed, for all purposes of the deposit agreement and the ADRs, to constitute notice to any and all beneficial owners of the ADSs evidenced by such ADR holder’s ADRs.

Unless certificated ADRs are specifically requested, all ADSs will be issued on the books of our depositary in book-entry form and periodic statements will be mailed to you which reflect your ownership interest in such ADSs. In our description, references to American depositary receipts or ADRs shall include the statements you will receive that reflect your ownership of ADSs.

You may hold ADSs either directly or indirectly through your broker or other financial institution. If you hold ADSs directly, by having an ADS registered in your name on the books of the depositary, you are an ADR holder. This description assumes you hold your ADSs directly. If you hold the ADSs through your broker or financial institution nominee, you must rely on the procedures of such broker or financial institution to assert the rights of an ADR holder described in this section. You should consult with your broker or financial institution to find out what those procedures are.

As an ADR holder or beneficial owner, we will not treat you as a shareholder of ours and you will not have any shareholder rights. Cayman Island law governs shareholder rights. Because the depositary or its nominee will be the shareholder of record for the shares represented by all outstanding ADSs, shareholder rights rest with such record holder. Your rights are those of an ADR holder or of a beneficial owner. Such rights derive from the terms of the deposit agreement to be entered into among us, the depositary and all holders and beneficial owners from time to time of ADRs issued under the deposit agreement and, in the case of a beneficial owner, from the arrangements between the beneficial owner and the holder of the corresponding ADRs. The obligations of our company and the depositary and its agents are also set out in the deposit agreement. Because the depositary or its nominee will actually be the registered owner of the shares, you must rely on it to exercise the rights of a shareholder on your behalf.

The deposit agreement, the ADRs and the ADSs are governed by the internal laws of the State of New York without giving effect to the application of the conflict of law principles thereof. Under the deposit agreement, as an ADR holder or a beneficial owner of ADSs, you agree that any legal suit, action or proceeding against or involving us or the depositary, arising out of or based upon the deposit agreement, the ADSs, the ADRs or the transactions contemplated thereby, may only be instituted by you in the United States

TABLE OF CONTENTS

District Court for the Southern District of New York (or, in certain cases, the state courts of New York County, New York), and you irrevocably waive any objection which you may have to the laying of venue of any such proceeding and irrevocably submit to the exclusive jurisdiction of such courts in any such suit, action or proceeding.

The following is a summary of what we believe to be the material terms of the deposit agreement. Notwithstanding this, because it is a summary, it may not contain all the information that you may otherwise deem important. For more complete information, you should read the entire deposit agreement and the form of ADR that contains the terms of your ADSs. You can read a copy of the deposit agreement, which is filed as an exhibit to the registration statement (or amendment thereto) filed with the U.S. Securities and Exchange Commission (the “SEC”) of which this prospectus forms a part. You may also obtain a copy of the deposit agreement at the SEC’s Public Reference Room, which is currently located at 100 F Street, NE, Washington, DC 20549. You may obtain information on the operation of the Public Reference Room by calling the SEC at 1-800-732-0330. You may also find the registration statement and the attached deposit agreement on the SEC’s website at http://www.sec.gov.

Distributions on Deposited Securities, Sales

How will I receive dividends and other distributions on the shares underlying my ADSs?

We may make various types of distributions with respect to our securities. The depositary has agreed that, to the extent practicable, it will pay to you the cash dividends or other distributions it or the custodian receives on shares or other deposited securities, after converting any cash received into U.S. dollars (if it determines such conversion may be made on a reasonable basis) and, in all cases, making any necessary deductions provided for in the deposit agreement. The depositary may utilize a division, branch or affiliate of JPMorgan to direct, manage and/or execute any public and/or private sale of securities and/or property under the deposit agreement. Such division, branch and/or affiliate may charge the depositary a fee in connection with such sales, which fee is considered an expense of the depositary chargeable to holders of ADSs. All sales of securities will be handled by the depositary in accordance with its then current policies. You will receive these distributions in proportion to the number of underlying securities that your ADSs represent. In all instances where the deposit agreement or an ADR refers to a “sale” ​(or words of similar import) of securities or property, the depositary shall not be obligated to effect any such sale unless the securities to be sold are listed and publicly traded on a securities exchange or there is a public market for the property to be sold. To the extent the securities are not so listed and publicly traded or there is no public market for the property so distributed by us: (i) the depositary shall, in the event the deposit agreement is terminated and the depositary holds deposited securities that are not listed and publicly traded after the termination date of the deposit agreement, act in accordance with the termination provisions of the deposit agreement and form of ADR in respect of such securities and property; and (ii) in the event the depositary or its custodian receives a distribution other than cash, our shares and/or rights to acquire our shares, and such distribution consists of securities or property that are not distributed by the depositary the depositary will be deemed to have sold the aggregate number of securities and/or property so received for nominal value and shall have no obligation to distribute such securities or any proceeds from the deemed sale thereof to the ADR holders. Furthermore, in the event the depositary endeavors to make a sale of shares, other securities or property, such securities and/or property may be sold in a block sale or single lot transaction.

Except as stated below, the depositary will deliver such distributions to ADR holders in proportion to their interests in the following manner:

​

•

Cash.   The depositary will distribute any U.S. dollars available to it resulting from a cash dividend or other cash distribution or the net proceeds of sales of any other distribution or portion thereof (to the extent applicable), on an averaged or other practicable basis, subject to (i) appropriate adjustments for taxes withheld, (ii) such distribution being permissible or practicable with respect to certain registered ADR holders, and (iii) deduction of the depositary’s and/or its agents’ fees and expenses in (1) converting any foreign currency to U.S. dollars to the extent that it determines that such conversion may be made on a reasonable basis, (2) transferring foreign currency or U.S. dollars to the United States by such means as the depositary may determine to the extent that it determines that such transfer may be made on a reasonable basis, (3) obtaining any approval or license of any governmental authority

​

TABLE OF CONTENTS

required for such conversion or transfer, which is obtainable at a reasonable cost and within a reasonable time and (4) making any sale by public or private means in any commercially reasonable manner. To the extent that any of the deposited securities is not or shall not be entitled, by reason of its date of issuance, or otherwise, to receive the full amount of such cash dividend, distribution, or net proceeds of sales, the depositary shall make appropriate adjustments in the amounts distributed to the ADR holders issued in respect of such deposited securities. To the extent we or the depositary shall be required to withhold and do withhold from any cash dividend, distribution or net proceeds from sales in respect of any deposited securities an amount on account of taxes, the amount distributed on the ADSs issued in respect of such deposited securities shall be reduced accordingly.

To the extent the depositary determines in its discretion that it would not be permitted by applicable law, rule or regulation, or it would not otherwise be practicable, to convert foreign currency into U.S. dollars and distribute such U.S. dollars to some or all of the ADR holders entitled thereto, the depositary may in its discretion distribute some or all of the foreign currency received by the depositary as it deems permissible and practicable to, or retain and hold such foreign currency uninvested and without liability for interest thereon for the respective accounts of, the ADR holders entitled to receive the same. To the extent the depositary retains and holds any cash, foreign currency, securities or other property as permitted under the deposit agreement, any and all fees, charges and expenses related to, or arising from, the holding thereof shall be paid from such cash, foreign currency, securities or other property, or the net proceeds from the sale thereof, thereby reducing the amount so held. If exchange rates fluctuate during a time when the depositary cannot convert a foreign currency, you may lose some or all of the value of the distribution.

​

•

Shares.   In the case of a distribution in shares, the depositary will issue additional ADRs to evidence the number of ADSs representing such shares. Only whole ADSs will be issued. Any shares that would result in fractional ADSs will be sold and the net proceeds of the public or private sales of such will be distributed in the same manner as cash to the ADR holders entitled thereto.

​

​

•

Rights to receive additional shares.   In the case of a distribution of rights to subscribe for additional shares or other rights, if we timely provide evidence satisfactory to the depositary that it may lawfully distribute such rights, the depositary will distribute warrants or other instruments in the discretion of the depositary representing such rights. However, if we do not timely furnish such evidence, the depositary may:

​

​

(i)

sell such rights if practicable and distribute the net proceeds of the public or private sales of such rights in the same manner as cash to the ADR holders entitled thereto; or

​

​

(ii)

if it is not practicable to sell such rights by reason of the non-transferability of the rights, limited markets therefor, their short duration or otherwise, do nothing and allow such rights to lapse, in which case ADR holders will receive nothing and the rights may lapse.

​

We have no obligation to file a registration statement under the Securities Act in order to make any rights available to ADR holders.

​

•

Other Distributions.   In the case of a distribution of securities or property other than those described above, the depositary may either (i) distribute such securities or property in any manner it deems equitable and practicable or (ii) to the extent the depositary deems distribution of such securities or property not to be equitable and practicable, sell such securities or property and distribute any net proceeds of public or private sales in the same way it distributes cash.

​

​

•

Elective Distributions.   In the case of a dividend payable at the election of our shareholders in cash or in additional ordinary shares, we will notify the depositary at least 30 days prior to the proposed distribution stating whether or not we wish such elective distribution to be made available to ADR holders. The depositary shall make such elective distribution available to ADR holders only if (i) we shall have timely requested that the elective distribution is available to ADR holders, (ii) the depositary shall have determined that such distribution is reasonably practicable and (iii) the depositary shall have received satisfactory documentation within the terms of the deposit agreement including any legal opinions of counsel that the depositary in its reasonable discretion may request. If the above conditions are not satisfied, the depositary shall, to the extent permitted by law, distribute to the ADR holders, on

​

21

TABLE OF CONTENTS

the basis of the same determination as is made in the local market in respect of the ordinary shares for which no election is made, either (x) cash or (y) additional ADSs representing such additional ordinary shares. If the above conditions are satisfied, the depositary shall establish procedures to enable ADR holders to elect the receipt of the proposed dividend in cash or in additional ADSs. There can be no assurance that ADR holders or beneficial owners of ADSs generally, or any ADR holder or beneficial owner of ADSs in particular, will be given the opportunity to receive elective distributions on the same terms and conditions as the holders of ordinary shares.

If the depositary determines in its sole discretion that any distribution described above is not practicable with respect to any or all ADR holders, the depositary may choose any method of distribution that it deems practicable for such ADR holder, including the distribution of some or all of any cash, foreign currency, securities or other property (or appropriate documents evidencing the right to receive some or all of any such cash, foreign currency, security or other property), and/or it may retain some or all of such items, without paying interest on or investing them, on behalf of the ADR holder as deposited securities, in which case the ADSs will also represent the retained items. To the extent the depositary does not reasonably believe it will be permitted by applicable law, rule or regulation to convert foreign currency into U.S. dollars and distribute such U.S. dollars to some or all of the ADR holders, the depositary may in its discretion distribute the foreign currency received by the depositary to, or hold such foreign currency uninvested and without liability for interest thereon for the respective accounts of, the ADR holders entitled to receive the same. To the extent the depositary holds such foreign currency, any and all costs and expenses related to, or arising from, the holding of such foreign currency shall be paid from such foreign currency thereby reducing the amount so held.

Any U.S. dollars will be paid via wire transfer and/or distributed by checks drawn on a bank in the United States for whole dollars and cents. Fractional cents will be withheld without liability and dealt with by the depositary in accordance with its then current practices.

The depositary is not responsible if it fails to determine that any distribution or action is lawful or reasonably practicable.

There can be no assurance that the depositary will be able to convert any currency at a specified exchange rate or sell any property, rights, shares or other securities at a specified price, nor that any of such transactions can be completed within a specified time period. All purchases and sales of securities will be handled by the depositary in accordance with its then current policies, which are currently set forth on the “Disclosures” page (or successor page) of www.adr.com (as updated by the depositary from time to time, “ADR.com”).

Deposit, Withdrawal and Cancellation

How does the depositary issue ADSs?

The depositary will issue ADSs if you or your broker deposit shares or evidence of rights to receive shares with the custodian and pay the fees and expenses owing to the depositary in connection with such issuance. In the case of the ADSs to be issued under this prospectus, we will arrange with the underwriters named herein to deposit such shares.

Shares deposited in the future with the custodian must be accompanied by certain delivery documentation and shall, at the time of such deposit, be registered in the name of “JPMorgan Chase Bank, N.A., as depositary for the benefit of holders of ADRs” or in such other name as the depositary shall direct.

The custodian will hold all deposited shares (including those being deposited by or on our behalf in connection with the offering to which this prospectus relates) for the account and to the order of the depositary, in each case for the benefit of ADR holders, to the extent not prohibited by law. ADR holders and beneficial owners thus have no direct ownership interest in the shares and only have such rights as are contained in the deposit agreement. The custodian will also hold any additional securities, property and cash received on or in substitution for the deposited shares. The deposited shares and any such additional items are referred to as “deposited securities.”

Deposited securities are not intended to, and shall not, constitute proprietary assets of the depositary, the custodian or their nominees. Beneficial ownership in deposited securities is intended to be, and shall at all times during the term of the deposit agreement continue to be, vested in the beneficial owners of the ADSs

22

TABLE OF CONTENTS

representing such deposited securities. Notwithstanding anything else contained herein, in the deposit agreement, in the form of ADR and/or in any outstanding ADSs, the depositary, the custodian and their respective nominees are intended to be, and shall at all times during the term of the deposit agreement be, the record holder(s) only of the deposited securities represented by the ADSs for the benefit of the ADR holders. The depositary, on its own behalf and on behalf of the custodian and their respective nominees, disclaims any beneficial ownership interest in the deposited securities held on behalf of the ADR holders.

Upon each deposit of shares, receipt of related delivery documentation and compliance with the other provisions of the deposit agreement, including the payment of the fees and charges of the depositary and any taxes or other fees or charges owing, the depositary will issue an ADR or ADRs in the name or upon the order of the person entitled thereto evidencing the number of ADSs to which such person is entitled. All of the ADSs issued will, unless specifically requested to the contrary, be part of the depositary’s direct registration system, and a registered holder will receive periodic statements from the depositary which will show the number of ADSs registered in such ADR holder’s name. An ADR holder can request that the ADSs not be held through the depositary’s direct registration system and that a certificated ADR be issued.

How do ADR holders cancel an ADS and obtain deposited securities?

When you turn in your ADR certificate at the depositary’s office, or when you provide proper instructions and documentation in the case of direct registration ADSs, subject to the provisions of or governing our shares (including, without limitation, our governing documents and all applicable laws, rules and regulations), the depositary will, upon payment of certain applicable fees, charges and taxes, deliver the underlying shares to you or upon your written order. Delivery of deposited securities in certificated form will be made at the custodian’s office (or from the custodian to the extent dematerialized). At your risk, expense and request, the depositary may deliver deposited securities (including any certificates therefor) at such other place as you may request.

The depositary may only restrict the withdrawal of deposited securities in connection with:

​

•

temporary delays caused by closing our transfer books or those of the depositary or the deposit of shares in connection with voting at a shareholders’ meeting, or the payment of dividends;

​

​

•

the payment of fees, taxes and similar charges; or

​

​

•

compliance with any U.S. or foreign laws or governmental regulations relating to the ADRs or to the withdrawal of deposited securities.

​

This right of withdrawal may not be limited by any other provision of the deposit agreement.

Record Dates

To the extent applicable to the ADRs, the depositary may, after consultation with us if practicable and related to a corresponding record date set by us, fix a record date for the ADRs (which, to the extent applicable, shall be as near as practicable to any corresponding record dates set by us) for the determination of the registered ADR holders who will be:

​

•

responsible for the fee assessed by the depositary for administration of the ADR program and for any other amounts provided for in the Deposit Agreement and/or ADR,

​

​

•

entitled to receive any distribution on or in respect of deposited securities,

​

​

•

entitled to give instructions for the exercise of any voting rights, and/or

​

​

•

eligible to receive any notice or to act in respect of other matters that only ADR holders shall be so entitled or obligated,

​

all subject to the provisions of the deposit agreement.

Voting Rights

How do I vote?

If you are an ADR holder and the depositary asks you to provide it with voting instructions, you may instruct the depositary how to exercise the voting rights for the shares which underlie your ADSs. As soon as

23

TABLE OF CONTENTS

practicable after receipt from us of notice of any meeting at which the holders of shares are entitled to vote, or of our solicitation of consents or proxies from holders of shares, the depositary shall fix the ADS record date in accordance with the provisions of the deposit agreement, provided that if the depositary receives a written request from us in a timely manner and at least thirty (30) days prior to the date of such vote or meeting, the depositary shall, at our expense, distribute to the registered ADR holders a “voting notice” stating (i) final information particular to such vote and meeting and any solicitation materials, (ii) that each ADR holder on the record date set by the depositary will, subject to any applicable provisions of the laws of the Cayman Islands, be entitled to instruct the depositary as to the exercise of the voting rights, if any, pertaining to the deposited securities represented by the ADSs evidenced by such ADR holder’s ADRs and (iii) the manner in which such instructions may be given or deemed given, including instructions for giving a discretionary proxy to a person designated by us. Each ADR holder shall be solely responsible for the forwarding of voting notices to the beneficial owners of ADSs registered in such ADR holder’s name. There is no guarantee that ADR holders and beneficial owners generally or any holder or beneficial owner in particular will receive the notice described above with sufficient time to enable such ADR holder or beneficial owner to return any voting instructions to the depositary in a timely manner.

Following actual receipt by the ADR department responsible for proxies and voting of ADR holders’ instructions (including, without limitation, instructions of any entity or entities acting on behalf of the nominee for DTC), the depositary shall, in the manner and on or before the time established by the depositary for such purpose, endeavor to vote or cause to be voted the deposited securities represented by the ADSs evidenced by such ADR holders’ ADRs in accordance with such instructions insofar as practicable and permitted under the provisions of or governing deposited securities.

To the extent that (A) the depositary has been provided with at least thirty-five (35) days’ notice of the proposed meeting from us, (B) the voting notice sent by the depositary will be received by all registered and beneficial ADR holders no less than ten (10) days prior to the date of the meeting and/or the cut-off date for the solicitation of consents, and (C) the depositary does not receive instructions on a particular agenda item from an ADR holder (including, without limitation, any entity or entities acting on behalf of the nominee for DTC) in a timely manner, such ADR holder shall be deemed, and the depositary is instructed to deem such ADR holder, to have instructed the depositary to give a discretionary proxy for such agenda item(s) to a person designated by us to vote the shares represented by the ADSs for which actual instructions were not so given by all such ADR holders on such agenda item(s), provided that no such instruction shall be deemed given and no discretionary proxy shall be given unless (1) we inform the depositary in writing that (a) we wish such proxy to be given with respect to such agenda item(s), (b) there is no substantial opposition existing with respect to such agenda item(s) and (c) such agenda item(s), if approved, would not materially or adversely affect the rights of holders of shares, and (2) the depositary has obtained an opinion of counsel, in form and substance satisfactory to it, confirming that (i) the granting of such discretionary proxy does not subject the depositary to any reporting obligations in the Cayman Islands, (ii) the granting of such proxy will not result in a violation of the laws, rules, regulations or permits of the Cayman Islands, (iii) the voting arrangement and deemed instruction as contemplated herein will be given effect under the laws, rules and regulations of the Cayman Islands, and (iv) the granting of such discretionary proxy will not under any circumstances result in the Shares represented by the ADSs being treated as assets of the Depositary under the laws, rules or regulations of the Cayman Islands. Neither the depositary, its custodian nor any of its or their respective agents shall incur any liability (i) as a result of our failure to determine that any of the circumstances described in (1)(b) or (1)(c) above exist or our failure to timely notify the depositary of any such circumstances or (ii) if any agenda item which is approved at a meeting has, or is claimed to have, a material or adverse effect on the rights of holders of Shares.

Because there is no guarantee that ADR holders will receive voting notices with sufficient time to enable such ADR holders to return any voting instructions to the depositary in a timely manner, ADR holders may be deemed to have instructed the depositary to give a discretionary proxy to a person designated by us in such circumstances, and neither the depositary, its custodian nor any of its or their respective agents shall incur any liability to ADR holders or others in such circumstances.

Under Cayman Islands law and our memorandum and articles of association, each as in effect as of the date of this prospectus, voting at any meeting of our shareholders is by show of hands unless a poll is (before or on the declaration of the results of the show of hands or on the withdrawal of any other demand for a poll)

24

TABLE OF CONTENTS

demanded. In the event that voting on any resolution or matter is conducted on a show of hands basis in accordance with our memorandum and articles of association, the depositary will refrain from voting and the voting instructions received by the depositary shall lapse. The depositary will not demand a poll or join in demanding a poll, whether or not requested to do so.

ADR holders are strongly encouraged to forward their voting instructions to the depositary as soon as possible. For instructions to be valid, the ADR department of the depositary that is responsible for proxies and voting must receive them in the manner and on or before the time specified, notwithstanding that such instructions may have been physically received by the depositary prior to such time. The depositary will not itself exercise any voting discretion in respect of deposited securities. The depositary and its agents will not be responsible for any failure to carry out any instructions to vote any of the deposited securities, for the manner in which any voting instructions are given, including instructions to give a discretionary proxy to a person designated by us, for the manner in which any vote is cast, including, without limitation, any vote cast by a person to whom the depositary is instructed to grant a discretionary proxy pursuant to the terms of the deposit agreement, or for the effect of any such vote.

Notwithstanding anything contained in the deposit agreement or any ADR, the depositary may, to the extent not prohibited by any law, rule or regulation, or by the rules, regulations or requirements of any stock exchange on which the ADSs are listed, in lieu of distribution of the materials provided to the depositary in connection with any meeting of or solicitation of consents or proxies from holders of deposited securities, distribute to the registered holders of ADRs a notice that provides such ADR holders with or otherwise publicizes to such ADR holders instructions on how to retrieve such materials or receive such materials upon request (i.e., by reference to a website containing the materials for retrieval or a contact for requesting copies of the materials).

There is no guarantee that you will receive voting materials in time to instruct the depositary to vote and it is possible that you, or persons who hold their ADSs through brokers, dealers or other third parties, will not have the opportunity to exercise a right to vote.

Reports and Other Communications

Will ADR holders be able to view our reports?

The deposit agreement, the provisions of or governing deposited securities, and any written communications from us which are both received by the custodian or its nominee as a holder of deposited securities and made generally available to the holders of deposited securities, are available for inspection by ADR holders at the offices of the depositary in the United States, on the SEC’s internet website or upon request to the depositary (which request may be refused by the depositary at its discretion).

Additionally, if we make any written communications generally available to holders of our shares, and we furnish copies thereof (or English translations or summaries) to the depositary, it will distribute the same to registered ADR holders.

Fees and Expenses

What fees and expenses will I be responsible for paying?

The depositary may charge each person to whom ADSs are issued, including, without limitation, issuances against deposits of shares, issuances in respect of share distributions, rights and other distributions, issuances pursuant to a stock dividend or stock split declared by us or issuances pursuant to a merger, exchange of securities or any other transaction or event affecting the ADSs or deposited securities, and each person surrendering ADSs for withdrawal of deposited securities or whose ADSs are cancelled or reduced for any other reason, a fee of up to $5.00 for each 100 ADSs (or any portion thereof) issued, delivered, reduced, cancelled or surrendered, or upon which a share distribution or elective distribution is made or offered, as the case may be. The depositary may sell (by public or private sale) sufficient securities and property received in respect of a share distribution, rights and/or other distribution prior to such deposit to pay such charge.

The following additional fees, charges and expenses shall also be incurred by the ADR holders, the beneficial owners, by any party depositing or withdrawing shares or by any party surrendering ADSs and/or

​

​

•

an amount for the reimbursement of such charges and expenses as are incurred by the depositary and/or any of its agents (including, without limitation, the custodian, as well as charges and expenses incurred on behalf of ADR holders in connection with compliance with foreign exchange control regulations or any law, rule or regulation relating to foreign investment) in connection with the servicing of the shares or other deposited securities, the sale of securities (including, without limitation, deposited securities), the delivery of deposited securities or otherwise in connection with the depositary’s or its custodian’s compliance with applicable law, rule or regulation (which fees and charges shall be assessed on a proportionate basis against ADR holders as of the record date or dates set by the depositary and shall be payable at the sole discretion of the depositary by billing such ADR holders or by deducting such charge from one or more cash dividends or other cash distributions);

​

​

​

​

​

To facilitate the administration of various depositary receipt transactions, including disbursement of dividends or other cash distributions and other corporate actions, the depositary may engage the foreign exchange desk within the banking division of JPMorgan (the “Bank”) and/or its affiliates in order to enter into spot foreign exchange transactions to convert foreign currency into U.S. dollars. For certain currencies, foreign exchange transactions are entered into with the Bank or an affiliate, as the case may be, acting in a principal capacity. For other currencies, foreign exchange transactions are routed directly to and managed by an unaffiliated local custodian (or other third party local liquidity provider), and neither the Bank nor any of its affiliates is a party to such foreign exchange transactions.

The foreign exchange rate applied to a foreign exchange transaction will be either (a) a published benchmark rate, or (b) a rate determined by a third party local liquidity provider, in each case plus or minus a spread, as applicable. The depositary will disclose which foreign exchange rate and spread, if any, apply to such currency on the “Disclosures” page (or successor page) of ADR.com. Such applicable foreign exchange rate and spread may (and neither the depositary, the Bank nor any of their affiliates is under any obligation to ensure that such rate does not) differ from rates and spreads at which comparable transactions are entered into with other customers or the range of foreign exchange rates and spreads at which the Bank or any of its affiliates enters into foreign exchange transactions in the relevant currency pair on the date of the foreign exchange transaction. Additionally, the timing of execution of a foreign exchange transaction varies according

26

TABLE OF CONTENTS

to local market dynamics, which may include regulatory requirements, market hours and liquidity in the foreign exchange market or other factors. Furthermore, the Bank and its affiliates may manage the associated risks of their position in the market in a manner they deem appropriate without regard to the impact of such activities on the depositary, us, ADR holders or beneficial owners. The spread applied does not reflect any gains or losses that may be earned or incurred by the Bank and its affiliates as a result of risk management or other hedging related activity.

Notwithstanding the foregoing, to the extent we provide U.S. dollars to the depositary, neither the Bank nor any of its affiliates will execute a foreign exchange transaction as set forth herein. In such case, the depositary will distribute the U.S. dollars received from us.

Further details relating to the applicable foreign exchange rate, the applicable spread and the execution of foreign exchange transactions will be provided by the depositary on ADR.com. Each holder and beneficial owner by holding or owning an ADR or ADS or an interest therein, and we, each acknowledge and agree that the terms applicable to foreign exchange transactions disclosed from time to time on ADR.com will apply to any foreign exchange transaction executed pursuant to the deposit agreement.

We will pay all other fees, charges and expenses of the depositary and any agent of the depositary (except the custodian) pursuant to agreements from time to time between us and the depositary.

The right of the depositary to charge and receive payment of fees, charges and expenses survives the termination of the deposit agreement, and shall extend for those fees, charges and expenses incurred prior to the effectiveness of any resignation or removal of the depositary.

The fees and charges described above may be amended from time to time by agreement between us and the depositary.

The depositary anticipates reimbursing us for certain expenses incurred by us that are related to the maintenance of the ADR program upon such terms and conditions as we and the depositary may agree from time to time. The depositary may make available to us a set amount or a portion of the depositary fees charged in respect of the ADR program or otherwise upon such terms and conditions as we and the depositary may agree from time to time. Under certain limited circumstances the depositary may also agree to reduce or waive certain fees that would normally be charged on ADSs issued to or at the director of, or otherwise held by, us and/or certain holders and beneficial owners and holders and beneficial owners of shares of ours. The depositary collects its fees for issuance and cancellation of ADSs directly from investors depositing shares or surrendering ADSs for the purpose of withdrawal or from intermediaries acting for them. The depositary collects fees for making distributions to investors by deducting those fees from the amounts distributed or by selling a portion of distributable property to pay the fees. The depositary may collect its annual fee for depositary services by deduction from cash distributions, or by directly billing investors, or by charging the book-entry system accounts of participants acting for them. The depositary will generally set off the amounts owing from distributions made to holders of ADSs. If, however, no distribution exists and payment owing is not timely received by the depositary, the depositary may refuse to provide any further services to ADR holders that have not paid those fees and expenses owing until such fees and expenses have been paid. At the discretion of the depositary, all fees and charges owing under the deposit agreement are due in advance and/or when declared owing by the depositary.

Payment of Taxes

ADR holders and/or beneficial owners must pay any tax or other governmental charge payable by the custodian or the depositary on any ADS or ADR, deposited security or distribution. If any taxes or other governmental charges (including any penalties and/or interest) shall become payable by or on behalf of the custodian or the depositary with respect to any ADR, any deposited securities represented by the ADSs evidenced thereby or any distribution thereon, including, without limitation, any Chinese enterprise income tax owed if the Circular Guoshuifa [2009] No. 82 issued by the Chinese State Administration of Taxation (SAT) or any other circular, edict, order or ruling, as issued and as from time to time amended, is applied or otherwise such tax or other governmental charge shall be paid by the ADR holder thereof to the depositary and by holding or owning, or having held or owned, an ADR or any ADSs evidenced thereby, the ADR holder and all beneficial owners thereof, and all prior ADR holders and beneficial owners thereof, jointly and

27

TABLE OF CONTENTS

severally, agree to indemnify, defend and save harmless each of the depositary and its agents in respect of such tax or other governmental charge. Notwithstanding the depositary’s right to seek payment from current or former ADR holders and beneficial owners, each ADR holder and beneficial owner, and each prior ADR holder and beneficial owner, by holding or owning, or having held or owned, an ADR or an interest in ADSs acknowledges and agrees that the depositary has no obligation to seek payment of amounts owing from any current or prior beneficial owner. If an ADR holder owes any tax or other governmental charge, the depositary may (i) deduct the amount thereof from any cash distributions, or (ii) sell deposited securities (by public or private sale) and deduct the amount owing from the net proceeds of such sale. In either case, the ADR holder remains liable for any shortfall. If any tax or governmental charge is unpaid, the depositary may also refuse to effect any registration, registration of transfer, split-up or combination of ADRs or withdrawal of deposited securities until such payment is made. If any tax or governmental charge is required to be withheld on any cash distribution, the depositary may deduct the amount required to be withheld from any cash distribution or, in the case of a non-cash distribution, sell the distributed property or securities (by public or private sale) in such amounts and in such manner as the depositary deems necessary and practicable to pay such taxes and distribute any remaining net proceeds or the balance of any such property after deduction of such taxes to the ADR holders entitled thereto. Neither we nor the depositary nor any of our or its respective agents, shall be liable to ADR holders or beneficial owners of the ADSs for failure of any of them to comply with applicable tax laws, rules and/or regulations.

As an ADR holder or beneficial owner, you will be agreeing to indemnify us, the depositary, its custodian and any of our or their respective officers, directors, employees, agents and affiliates against, and hold each of them harmless from, any claims by any governmental authority with respect to taxes, additions to tax, penalties or interest arising out of any refund of taxes, reduced rate of withholding at source or other tax benefit obtained, which obligations shall survive any transfer or surrender of ADSs or the termination of the deposit agreement.

Reclassifications, Recapitalizations and Mergers

If we take certain actions that affect the deposited securities, including (i) any change in par value, split-up, consolidation, cancellation or other reclassification of deposited securities or (ii) any distributions of shares or other property not made to holders of ADRs or (iii) any recapitalization, reorganization, merger, consolidation, liquidation, receivership, bankruptcy or sale of all or substantially all of our assets, then the depositary may choose to, and shall if reasonably requested by us:

​

•

amend the form of ADR;

​

​

•

distribute additional or amended ADRs;

​

​

•

distribute cash, securities or other property it has received in connection with such actions;

​

​

•

sell by public or private sale any securities or property received and distribute the proceeds as cash; or

​

​

•

none of the above.

​

If the depositary does not choose any of the above options, any of the cash, securities or other property it receives will constitute part of the deposited securities and each ADS will then represent a proportionate interest in such property.

Amendment and Termination

How may the deposit agreement be amended?

We may agree with the depositary to amend the deposit agreement and the ADSs without your consent for any reason. ADR holders must be given at least thirty (30) days’ notice of any amendment that imposes or increases any fees on a per ADS basis, charges or expenses (other than stock transfer or other taxes and other governmental charges, transfer or registration fees, a transaction fee per cancellation request (including any cancellation request made through SWIFT, facsimile transmission or any other method of communication), applicable delivery expenses or other such fees, charges or expenses), or otherwise prejudices any substantial existing right of ADR holders or beneficial owners. Such notice need not describe in detail the specific amendments effectuated thereby, but must identify to ADR holders and beneficial owners a means to access

28

TABLE OF CONTENTS

the text of such amendment. If an ADR holder or beneficial owner continues to hold an ADR or ADRs, or an interest therein, after being so notified, such ADR holder and any beneficial owner are deemed to agree to such amendment and to be bound by the deposit agreement as so amended. No amendment, however, will impair your right to surrender your ADSs and receive the underlying securities, except in order to comply with mandatory provisions of applicable law.

Any amendments or supplements that (i) are reasonably necessary (as agreed by us and the depositary) in order for (a) the ADSs to be registered on Form F-6 under the Securities Act or (b) the ADSs or shares to be traded solely in electronic book-entry form and (ii) do not in either such case impose or increase any fees or charges to be borne by ADR holders, shall be deemed not to prejudice any substantial rights of ADR holders or beneficial owners. Notwithstanding the foregoing, if any governmental body or regulatory body should adopt new laws, rules or regulations that would require amendment or supplement of the deposit agreement or the form of ADR to ensure compliance therewith, we and the depositary may amend or supplement the deposit agreement and the form of ADR (and all outstanding ADRs) at any time in accordance with such changed laws, rules or regulations. Such amendment or supplement to the deposit agreement in such circumstances may become effective before a notice of such amendment or supplement is given to ADR holders or within any other period of time as required for compliance.

Notice of any amendment to the deposit agreement or form of ADRs shall not need to describe in detail the specific amendments effectuated thereby, and failure to describe the specific amendments in any such notice shall not render such notice invalid, provided, however, that, in each such case, the notice given to the ADR holders identifies a means for ADR holders and beneficial owners to retrieve or receive the text of such amendment (i.e., upon retrieval from the SEC’s, the depositary’s or our website or upon request from the depositary).

How may the deposit agreement be terminated?

The depositary may at any time, and shall at our written direction, terminate the deposit agreement and the ADRs by mailing notice of such termination to the registered holders of ADRs at least thirty (30) days prior to the date fixed in such notice for such termination; provided, however, if the depositary shall have (i) resigned as depositary under the deposit agreement, notice of such termination by the depositary shall not be provided to registered ADR holders unless a successor depositary shall not be operating under the deposit agreement within sixty (60) days of the date of such resignation, and (ii) been removed as depositary under the deposit agreement, notice of such termination by the depositary shall not be provided to registered holders of ADRs unless a successor depositary shall not be operating under the deposit agreement on the 60th day after our notice of removal was first provided to the depositary. Notwithstanding anything to the contrary in the deposit agreement, the depositary may terminate the deposit agreement (a) without notifying us, but subject to giving thirty (30) days’ notice to the ADR holders, under the following circumstances: (i) in the event of our bankruptcy, liquidation proceedings or insolvency, (ii) if the ADRs are delisted from a “national securities exchange” ​(that has registered with the Commission under Section 6 of the Securities Exchange Act of 1934), (iii) if we effect (or will effect) a redemption of all or substantially all of the deposited securities, or a cash or share distribution representing a return of all or substantially all of the value of the deposited securities, (iv) there are no deposited securities with respect to ADSs remaining, including if the deposited securities are cancelled, or the deposit securities have been deemed to have no value, or (v) there occurs a merger, consolidation, sale of assets or other transaction as a result of which securities or other property are delivered in exchange for or in lieu of deposited securities, and (b) immediately without prior notice to the Company, any ADR holder or beneficial owner or any other person if (i) required by any law, rule or regulation relating to sanctions by any governmental authority or body, (ii) the depositary would be subject to liability under or pursuant to any law, rule or regulation, or (iii) required by any governmental authority or body, in each case under (b) as determined by the depositary in its reasonable discretion.

If our shares are not listed and publicly traded on a stock exchange or in a securities market as of the date so fixed for termination or if, for any reason, the depositary does not sell the deposited securities, then after such date fixed for termination, the depositary shall use its reasonable efforts to ensure that the ADSs cease to be eligible for settlement within The Depository Trust Company (DTC) and that neither DTC nor any of its nominees shall thereafter be an ADR holder. At such time as the ADSs cease to be DTC eligible and/or neither DTC nor any of its nominees is an ADR holder, to the extent we are not, to the depositary’s knowledge,

29

TABLE OF CONTENTS

insolvent or in bankruptcy or liquidation, the depositary shall (A) cancel all outstanding ADRs; (B) request DTC to provide the depositary with information on those holding ADSs through DTC and, upon receipt thereof, revise the ADR register to reflect the information provided by DTC; (C) instruct its custodian to deliver all deposited securities to us, a subsidiary or affiliate of ours (the company representative) or an independent trust company engaged by us (the trustee) to hold those deposited securities in trust for the beneficial owners of the ADRs if we are not permitted to hold any of the deposited securities under applicable law and/or we have directed the depositary to deliver such deposited securities to the company representative or trustee along with a stock transfer form and/or such other instruments of transfer covering such deposited securities as are needed under applicable law, in either case referring to the names set forth on the ADR register and (D) provide us with a copy of the ADR register.

Upon receipt of any instrument of transfer covering such deposited securities, any applicable share certificate or indemnity for lost share certificate and the ADR Register, we have agreed that we will, approve the transfer of the deposited securities previously represented by the ADSs evidenced by their ADRs the persons listed on the ADR register (as applicable), procure the relevant updates to the register of members of the Company to reflect the transfer of the deposited securities previously represented by their ADRs to the persons listed on the ADR register (as applicable) and provide the depositary with a certified copy of the updated register of our shareholders.

To the extent the depositary reasonably believes that we are insolvent, or if we are in receivership, have filed for bankruptcy and/or are otherwise in restructuring, administration or liquidation, and in any such case the deposited securities are not listed and publicly traded on a securities exchange after the termination date, or if, for any reason, the depositary believes it is not able to or cannot practicably sell the deposited securities promptly and without undue effort, the deposited securities shall be deemed to have no value (and such holder shall be deemed to have instructed the depositary that the deposited securities have no value). The depositary may (and, by holding an ADR or an interest therein, all holders irrevocably consent and agree that the depositary may) instruct its custodian to deliver all deposited securities to us (acting, as applicable by an administrator, receiver, administrative receiver, liquidator, provisional liquidator, restructuring officer, interim restructuring officer, trustee, controller or other entity overseeing the bankruptcy, insolvency, administration, restructuring or liquidation process) and notify us that the deposited shares are surrendered for no consideration. The deposit agreement requires us, subject to applicable law, to promptly accept the surrender of the deposited shares for no consideration and deliver to the depositary a written notice confirming (A) the acceptance of the surrender of the deposited securities for no consideration and (B) the cancellation of such deposited shares. Promptly after notifying us that the deposited shares are surrendered for no consideration and irrespective of whether we haves complied with the immediately preceding sentence, the depositary shall notify ADR holders that their ADSs have been cancelled with no consideration being payable to such ADR holders.

Upon the depositary’s compliance with the provisions of any of the above three paragraphs, the depositary and its agents shall be discharged from all, and cease to have any, obligations under the deposit agreement and the ADRs.

If our shares are listed and publicly traded on a securities exchange and the depositary believes that it is able, permissible and practicable to sell the deposited securities without undue effort, then the depositary may endeavor to publicly or privately sell (as long as it may lawfully do so) the deposited securities, which sale may be effected in a block sale/single lot transaction and, after the settlement of such sale(s), to the extent legally permissible and practicable, distribute or hold in an account (which may be a segregated or unsegregated account) the net proceeds of such sale(s), less any amounts owing to the depositary (including, without limitation, cancellation fees), together with any other cash then held by it under the deposit agreement, in trust, without liability for interest, for the pro rata benefit of the holders entitled thereto. After making such sale, the depositary shall be discharged from all obligations in respect of the deposit agreement and the ADRs, except to account for such net proceeds and other cash.

Notwithstanding anything to the contrary, in connection with any such termination, the depositary may, in its sole discretion and without notice to us, establish an unsponsored American depositary share program (on such terms as the depositary may determine) for our shares and make available to ADR holders a means to withdraw the shares represented by the ADSs issued under the deposit agreement and to direct the deposit of such shares into such unsponsored American depositary share program, subject, in each case, to receipt by

30

the depositary, at its discretion, of the fees, charges and expenses provided for under the deposit agreement and the fees, charges and expenses applicable to the unsponsored American depositary share program.

Limitations on Obligations and Liability

Limits on our obligations and the obligations of the depositary; limits on liability to ADR holders, beneficial owners and others

The deposit agreement expressly limits the obligations and liability of the depositary, the depositary’s custodian or ourselves and each of our and their respective directors, officers, employees, agents and affiliates, provided, however, that no provision of the deposit agreement is intended to constitute a waiver or limitation of any rights that ADR holders or beneficial owners may have under the Securities Act or the Securities Exchange Act of 1934, to the extent applicable. The deposit agreement provides that each of us, the depositary and our respective directors, officers, employees, agents and affiliates will:

​

​

•

may rely and shall be protected in acting upon any written notice, request, direction, instruction or document believed by it to be genuine and to have been signed, presented or given by the proper party or parties.

​

The depositary shall not be a fiduciary or have any fiduciary duty to ADR holders or beneficial owners.

The depositary and its agents may fully respond to any and all demands or requests for information maintained by or on its behalf in connection with the deposit agreement, any registered holder or holders of ADRs, any ADRs or otherwise related to the deposit agreement or ADRs to the extent such information is requested or required by or pursuant to any lawful authority, including without limitation laws, rules, regulations, administrative or judicial process, banking, securities or other regulators. The depositary shall not be liable for the acts or omissions made by, or the insolvency of, any securities depository, clearing agency or settlement system. Furthermore, the depositary shall not be responsible for, and shall incur no liability in connection with or arising from, the insolvency of any custodian that is not a branch or affiliate of JPMorgan. Notwithstanding anything to the contrary contained in the deposit agreement or any ADRs, the depositary shall not be responsible for, and shall incur no liability in connection with or arising from, any act or omission to act on the part of the custodian except to the extent that any registered ADR holder has incurred liability directly as a result of the custodian having (i) committed fraud or willful misconduct in the provision of custodial services to the depositary or (ii) failed to use reasonable care in the provision of custodial services to the depositary as determined in accordance with the standards prevailing in the jurisdiction in which the custodian is located. The depositary and the custodian(s) may use third party delivery services and providers of information regarding matters such as, but not limited to, pricing, proxy voting, corporate actions, class action litigation and other services in connection with the ADRs and the deposit agreement, and use local agents to provide services such as, but not limited to, attendance at any meetings of our security holders. Although the depositary and the custodian will use reasonable care (and cause their agents to use reasonable care) in the selection and retention of such third-party providers and local agents, they will not be responsible for any errors or omissions made by them in providing the relevant information or services.

The depositary has no obligation to inform ADR holders or beneficial owners about the requirements of the laws, rules or regulations or any changes therein or thereto of the Cayman Islands, Singapore, the People’s Republic of China , the United States or any other country or jurisdiction or of any governmental or regulatory authority or any securities exchange or market or automated quotation system.

Additionally, none of the depositary, the custodian or us, or any of their or our respective directors, officers, employees, agents or affiliates shall be liable for the failure by any registered holder of ADRs or

32

TABLE OF CONTENTS

beneficial owner to obtain the benefits of credits or refunds of non-U.S. tax paid against such ADR holder’s or beneficial owner’s income tax liability. The depositary is under no obligation to provide the ADR holders and beneficial owners, or any of them, with any information about our tax status. None of us, the depositary, the custodian or any of our or their respective directors, officers, employees, agents or affiliates shall incur any liability for any tax or tax consequences that may be incurred by registered ADR holders or beneficial owners on account of their ownership or disposition of ADRs or ADSs.

Neither the depositary nor its agents will be responsible for any failure to carry out any instructions to vote any of the deposited securities, for the manner in which any voting instructions are given, including instructions to give a discretionary proxy to a person designated by us, for the manner in which any vote is cast, including, without limitation, any vote cast by a person to whom the depositary is instructed to grant a discretionary proxy pursuant to the terms of the deposit agreement, or for the effect of any such vote. The depositary shall endeavor to effect any sale of securities or other property and any conversion of currency, securities or other property, in each case as is referred to or contemplated in the deposit agreement or the form of ADR, in accordance with the depositary’s normal practices and procedures under the circumstances applicable to such sale or conversion, but shall have no liability (in the absence of its own willful default or gross negligence or that of its agents, officers, directors or employees) with respect to the terms of any such sale or conversion, including the price at which such sale or conversion is effected, or if such sale or conversion shall not be practicable, or shall not be believed, deemed or determined to be practicable by the depositary. Specifically, the depositary shall not have any liability for the price received in connection with any public or private sale of securities (including, without limitation, for any sale made at a nominal price), the timing thereof or any delay in action or omission to act nor shall it be responsible for any error or delay in action, omission to act, default or negligence on the part of the party so retained in connection with any such sale or proposed sale. The depositary shall not incur any liability in connection with or arising from any failure, inability or refusal by us or any other party, including any share registrar, transfer agent or other agent appointed by us or the depositary or any other party, to process any transfer, delivery or distribution of cash, shares, other securities or other property, including without limitation upon the termination of the deposit agreement, or otherwise to comply with any provisions of the deposit agreement that are applicable to it. The depositary may rely upon instructions from us or our counsel in respect of any approval or license required for any currency conversion, transfer or distribution. The depositary shall not incur any liability for the content of any information submitted to it by us or on our behalf for distribution to ADR holders or for any inaccuracy of any translation thereof, for any investment risk associated with acquiring an interest in the deposited securities, for the validity or worth of the deposited securities, for the credit-worthiness of any third party, for allowing any rights to lapse upon the terms of the deposit agreement or for the failure or timeliness of any notice from us. The depositary shall not be liable for any acts or omissions made by a successor depositary whether in connection with a previous act or omission of the depositary or in connection with any matter arising wholly after the removal or resignation of the depositary. Neither the depositary nor any of its agents shall be liable for any indirect, special, punitive or consequential damages (including, without limitation, legal fees and expenses) or lost profits, in each case of any form incurred by any person or entity (including, without limitation ADR holders or beneficial owners), whether or not foreseeable and regardless of the type of action in which such a claim may be brought.

In the deposit agreement each party thereto (including, for avoidance of doubt, each ADR holder and beneficial owner) irrevocably waives, to the fullest extent permitted by applicable law, any right it may have to a trial by jury in any suit, action or proceeding against the depositary and/or us directly or indirectly arising out of or relating to the shares or other deposited securities, the ADSs or the ADRs, the deposit agreement or any transaction contemplated therein, or the breach thereof (whether based on contract, tort, common law or any other theory). No provision of the deposit agreement or the ADRs is intended to constitute a waiver or limitation of any rights which an ADR holder or any beneficial owner may have under the Securities Act or the Securities Exchange Act of 1934, to the extent applicable.

The depositary will maintain facilities for the delivery and receipt of ADRs.

Under the deposit agreement, by holding or owning an ADR or ADS or an interest therein, holders and beneficial owners each irrevocably agree that (i) any legal suit, action or proceeding against or involving holders or beneficial owners brought by us or the depositary, arising out of or based upon the deposit agreement, the ADSs, the ADRs or the transactions contemplated therein or thereby, may be instituted in a state or federal court in New York, New York, and by holding or owning an ADR or ADS or an interest therein each irrevocably waives any objection that it may now or hereafter have to the laying of venue of any such proceeding, and irrevocably submits to the non-exclusive jurisdiction of such courts in any such suit, action or proceeding and (ii) any legal suit, action or proceeding against or involving us and/or the depositary brought by holders or beneficial owners, arising out of or based upon the deposit agreement, the ADSs, the ADRs or the transactions contemplated therein or thereby, including, without limitation, claims under the Securities Act of 1933, may be instituted only in the United States District Court for the Southern District of New York (or in the state courts of New York County in New York if either (a) the United States District Court for the Southern District of New York lacks subject matter jurisdiction over a particular dispute or (b) the designation of the United States District Court for the Southern District of New York as the exclusive forum for any particular dispute is, or becomes, invalid, illegal or unenforceable). In the deposit agreement each holder and beneficial owner irrevocably waives any objection which it may at any time have to the laying of venue of any such proceeding, and irrevocably submits to the jurisdiction of such courts in any such suit, action or proceeding.

Notwithstanding anything in the deposit agreement to the contrary, by directly or indirectly holding or owing an ADR or ADS or an interest therein, holders and beneficial owners each agree that: (i) the depositary may, in its sole discretion, elect to institute any dispute, suit, action, controversy, claim or proceeding directly or indirectly based on, arising out of or relating to the deposit agreement, the ADSs, the ADRs or the transactions contemplated therein or thereby, including without limitation any question regarding its or their existence, validity, interpretation, performance or termination against any other party or parties, by having such dispute referred to and finally resolved by an arbitration. Any such arbitration shall, at the depositary’s election, be conducted either in New York, New York in accordance with the Commercial Arbitration Rules of the American Arbitration Association or in Hong Kong following the arbitration rules of the United Nations Commission on International Trade Law (UNCITRAL) with the Hong Kong International Arbitration Centre serving as the appointing authority and the language of any such arbitration shall be English. In all cases, the fees of the arbitrators and other costs incurred by the parties in connection with such arbitration shall be paid by the party (or parties) that is (or are) unsuccessful in such arbitration. Holders and beneficial owners shall not be entitled to join or consolidate disputes by or against others in any arbitration, or to include in any arbitration any dispute as a representative or member of a class, or act in any arbitration in the interest of the general public or in a private attorney general capacity.

Jury Trial Waiver

In the deposit agreement, each party thereto (including, for the avoidance of doubt, each holder and beneficial owner of, and/or holder of interests in, ADSs or ADRs) irrevocably waives, to the fullest extent permitted by applicable law, any right it may have to a trial by jury in any suit, action or proceeding against the depositary and/or us directly or indirectly arising out of, based on or relating in any way to the shares or other deposited securities, the ADSs or the ADRs, the deposit agreement or any transaction contemplated therein, or the breach thereof (whether based on contract, tort, common law or any other theory), including any claim under the U.S. federal securities laws.

If we or the depositary were to oppose a jury trial demand based on such waiver, the court would determine whether the waiver was enforceable in the facts and circumstances of that case in accordance with applicable state and federal law, including whether a party knowingly, intelligently and voluntarily waived the right to a jury trial. The waiver to right to a jury trial in the deposit agreement is not intended to be deemed a waiver by any holder or beneficial owner of our or the depositary’s compliance with the U.S. federal securities laws and the rules and regulations promulgated thereunder.

DESCRIPTION OF DEBT SECURITIES

General

We may issue debt securities which may or may not be converted into our ordinary shares. We may issue the debt securities independently or together with any underlying securities, and debt securities may be attached or separate from the underlying securities. In connection with the issuance of any debt securities, we do not intend to issue them pursuant to a trust indenture upon reliance of Section 304(a)(8) of the Trust Indenture Act and Rule 4a-1 promulgated thereunder.

The following description is a summary of selected provisions relating to the debt securities that we may issue. The summary is not complete. When debt securities are offered in the future, a prospectus supplement, information incorporated by reference, or a free writing prospectus, as applicable, will explain the particular terms of those securities and the extent to which these general provisions may apply. The specific terms of the debt securities as described in a prospectus supplement, information incorporated by reference, or free writing prospectus will supplement and, if applicable, may modify or replace the general terms described in this section.

This summary and any description of debt securities in the applicable prospectus supplement, information incorporated by reference, or free writing prospectus is subject to and is qualified in its entirety by reference to all the provisions of any specific debt securities document or agreement. We will file each of these documents, as applicable, with the SEC and incorporate them by reference as an exhibit to the registration statement of which this prospectus is a part on or before the time we issue a series of warrants. See “Where You Can Find More Information About Us” and “Incorporation of Documents by Reference” below for information on how to obtain a copy of a debt securities document when it is filed.

When we refer to a series of debt securities, we mean all debt securities issued as part of the same series under the applicable indenture.

Terms

The applicable prospectus supplement, information incorporated by reference, or free writing prospectus, may describe the terms of any debt securities that we may offer, including, but not limited to, the following:

•

the title of the debt securities;

​

•

the total amount of the debt securities;

​

​

​

•

​

•

​

Form, Exchange, and Transfer

We may issue the debt securities in registered form or bearer form. Debt securities issued in registered form, i.e., book-entry form, will be represented by a global security registered in the name of a depository,

39

TABLE OF CONTENTS

which will be the holder of all the debt securities represented by the global security. Those investors who own beneficial interests in global debt securities will do so through participants in the depository’s system, and the rights of these indirect owners will be governed solely by the applicable procedures of the depository and its participants. In addition, we may issue debt securities in non-global form, i.e., bearer form. If any debt securities are issued in non-global form, debt securities certificates may be exchanged for new debt securities certificates of different denominations, and holders may exchange, transfer, or convert their debt securities at the debt securities agent’s office or any other office indicated in the applicable prospectus supplement, information incorporated by reference or free writing prospectus.

Prior to the conversion of their debt securities, holders of debt securities convertible for ordinary shares will not have any rights of holders of ordinary shares, and will not be entitled to dividend payments, if any, or voting rights of the ordinary shares.

Conversion of Debt Securities

A debt security may entitle the holder to purchase, in exchange for the extinguishment of debt, an amount of securities at a conversion price that will be stated in the debt security. Debt securities may be converted at any time up to the close of business on the expiration date set forth in the terms of such debt security. After the close of business on the expiration date, debt securities not exercised will be paid in accordance with their terms.

Debt securities may be converted as set forth in the applicable offering material. Upon receipt of a notice of conversion properly completed and duly executed at the corporate trust office of the indenture agent, if any, or to us, we will forward, as soon as practicable, the securities purchasable upon such exercise. If less than all of the debt security represented by such security is converted, a new debt security will be issued for the remaining debt security.

ENFORCEABILITY OF CIVIL LIABILITIES

We are incorporated under the laws of the Cayman Islands as an exempted company with limited liability. We are incorporated in the Cayman Islands because of certain benefits associated with being a Cayman Islands company, such as political and economic stability, an effective judicial system, a favorable tax system, the absence of foreign exchange control or currency restrictions and the availability of professional and support services. However, the Cayman Islands has a less developed body of securities laws as compared to the United States and provides protections for investors to a lesser extent. In addition, Cayman Islands companies may not have standing to sue before the federal courts of the United States.

Most of our operations are conducted in China, and most of our assets are located in China. In addition, most of our directors and officers are residents of jurisdictions other than the United States and all or a substantial portion of their assets are located outside the United States. As a result, it may be difficult for investors to effect service of process within the United States upon us or these persons, or to enforce against us or them judgments obtained in United States courts, including judgments predicated upon the civil liability provisions of the securities laws of the United States or any state in the United States. It may also be difficult for you to enforce in United States courts judgments obtained in United States courts based on the civil liability provisions of the United States federal securities laws against us and our officers and directors.

We have appointed Cogency Global Inc. as our agent to receive service of process with respect to any action brought against us in the U.S. District Court for the Southern District of New York under the federal securities laws of the U.S. or of any state in the U.S. or any action brought against us in the Supreme Court of the State of New York in the County of New York under the securities laws of the State of New York.

Maples and Calder (Hong Kong) LLP, our counsel as to Cayman Islands law, has advised us that the courts of the Cayman Islands are unlikely (1) to recognize or enforce judgments of U.S. courts obtained against us or our directors or officers that are predicated upon the civil liability provisions of the federal securities laws of the United States or the securities laws of any state in the United States, or (2) in original actions brought in the Cayman Islands to impose liabilities against us or our directors or officers that are predicated upon the federal securities laws of the United States or the securities laws of any state in the United States so far as the liabilities imposed by those provisions are penal in nature.

In addition, Maples and Calder (Hong Kong) LLP has advised us that although there is no statutory enforcement in the Cayman Islands of judgments obtained in the federal or state courts of the United States (and the Cayman Islands are not a party to any treaties for the reciprocal enforcement or recognition of such judgments), a judgment obtained in such jurisdiction will be recognized and enforced in the courts of the Cayman Islands at common law, without any re-examination of the merits of the underlying dispute, by an action commenced on the foreign judgment debt in the Grand Court of the Cayman Islands, provided such judgment (i) is given by a foreign court of competent jurisdiction, (ii) imposes on the judgment debtor a liability to pay a liquidated sum for which the judgment has been given, (iii) is final and conclusive, (iv) is not in respect of taxes, a fine or a penalty, (v) is not inconsistent with a Cayman Islands judgment in respect of the same matter, and (vi) is not impeachable on the grounds of fraud and was not obtained in a manner and is not of a kind the enforcement of which is contrary to natural justice or the public policy of the Cayman Islands. A Cayman Islands court may stay enforcement proceedings if concurrent proceedings are being brought elsewhere.

Commerce & Finance Law Offices, our PRC legal adviser, has advised us that the recognition and enforcement of foreign judgments are provided for under the PRC Civil Procedure Law. PRC courts may recognize and enforce foreign judgments in accordance with the requirements of the PRC Civil Procedure Law based either on treaties between China and the country where the judgment is made or on principles of reciprocity between jurisdictions. Commerce & Finance Law Offices has advised us further that under PRC law, courts in the PRC will not recognize or enforce a foreign judgment against us or our directors and officers if they decide that the judgment violates the basic principles of PRC law or national sovereignty, security or social public interest. As there existed no treaty or other form of reciprocity between China and the United States governing the recognition and enforcement of judgments as of the date of this prospectus, including those predicated upon the liability provisions of the United States federal securities laws, there is uncertainty whether and on what basis a PRC court would enforce judgments rendered by United States courts. In addition, because there is no treaty or other form of reciprocity between the Cayman Islands and China governing the recognition and enforcement of judgments as of the date of this prospectus, there is further uncertainty as to whether and on what basis a PRC court would enforce judgments rendered by a Cayman Islands court.

TAXATION

Certain income tax considerations relating to the purchase, ownership and disposition of any of the securities other than ADS and ordinary shares offered by this prospectus will be set forth in the applicable prospectus supplement relating to the offering of those securities.

Income Tax Considerations Relevant to an investment in the ADS and Ordinary Shares

The following is summaries of certain material Cayman Islands, People’s Republic of China and United States federal income tax consequences relevant to an investment in the ADSs and ordinary shares. The discussion is not intended to be, nor should it be construed as, legal or tax advice to any particular prospective purchaser or holder. The discussion is based on laws and relevant interpretations thereof in effect as of the date of this prospectus, all of which are subject to change or different interpretations, possibly with retroactive effect. The discussion does not address U.S. state or local tax laws, or tax laws of jurisdictions other than the Cayman Islands, the People’s Republic of China and the United States. You should consult your own tax advisors with respect to the consequences of acquisition, ownership and disposition of the ADSs and ordinary shares.

Cayman Islands Taxation

Such section is the opinion of Maples and Calder (Hong Kong) LLP, our Cayman Islands counsel, insofar as it relates to legal conclusions with respect to matters of Cayman Islands tax law.

The Cayman Islands currently levies 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 or withholding tax applicable to us or to any holder of the ADSs and ordinary shares. There are no other taxes likely to be material to us levied by the government of the Cayman Islands except for stamp duties which may be applicable on instruments executed in, or after execution brought within the jurisdiction of, the Cayman Islands. Payments of dividends and capital in respect of the ADSs and ordinary 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 the ADSs and ordinary shares, nor will gains derived from the disposal of the ADSs and ordinary shares be subject to Cayman Islands income or corporation tax. There are no exchange control regulations or currency restrictions in the Cayman Islands.

People’s Republic of China Taxation

Such section is the opinion of Commerce & Finance Law Offices, our PRC counsel, insofar as it relates to legal conclusions with respect to matters of PRC tax law.

In March 2007, the National People’s Congress of China enacted the Enterprise Income Tax Law, which became effective on January 1, 2008 and was last revised on December 29, 2018. The Enterprise Income Tax Law provides that enterprises organized under the laws of jurisdictions outside China with their “de facto management bodies” located within China may be considered PRC resident enterprises and therefore subject to PRC enterprise income tax at the rate of 25% on their worldwide income. The Implementing Rules of the Enterprise Income Tax Law further define the term “de facto management body” as the management body that exercises substantial and overall management and control over the business, personnel, accounts and properties of an enterprise. While we do not consider our company or any of our overseas subsidiaries to be a PRC resident enterprise, there is a risk that the PRC tax authorities may deem our company or any of our overseas subsidiaries as a PRC resident enterprise since a substantial majority of the members of our management team as well as the management team of some of our overseas subsidiaries are located in China, in which case we or the overseas subsidiaries, as the case may be, would be subject to the PRC enterprise income tax at the rate of 25% on worldwide income. If the PRC tax authorities determine that our Cayman Islands holding company is a “resident enterprise” for PRC enterprise income tax purposes, a 10% withholding tax would be imposed on dividends we pay to our non-PRC enterprise shareholders and a 10% tax would be imposed with respect to gains derived by our non-PRC enterprise shareholders from transferring our shares or ADSs. Furthermore, dividends paid to individual investors who are non-PRC residents and any gain realized on the transfer of ADSs or ordinary shares by such investors may be subject to PRC tax at a rate of

45

TABLE OF CONTENTS

20% (which in the case of dividends may be withheld at source). Any PRC tax liability may be reduced by an applicable tax treaty. However, it is unclear whether, if we are considered a PRC resident enterprise, holders of our shares or ADSs would be able to claim the benefit of income tax treaties or agreements entered into between China and other countries or areas.

United States Federal Income Tax Considerations

The following discussion is a summary of the material United States federal income tax consequences of the purchase, ownership and disposition of the ADSs and ordinary shares as of the date hereof. This discussion deals only with ADSs and ordinary shares that are held as “capital assets” ​(generally, property held for investment) within the meaning of Section 1221 of the U.S. Internal Revenue Code of 1986, as amended, or the Code, by a United States Holder (as defined below).

As used herein, the term “United States Holder” means a beneficial owner of ADSs or ordinary shares that is, for United States federal income tax purposes, any of the following:

​

•

an individual citizen or resident of the United States;

​

​

•

a corporation (or other entity treated as a corporation for United States federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia;

​

​

•

an estate the income of which is subject to United States federal income taxation regardless of its source; or

​

​

•

a trust if it (1) is subject to the primary supervision of a court within the United States and one or more United States persons have the authority to control all substantial decisions of the trust or (2) has a valid election in effect under applicable United States Treasury regulations to be treated as a United States person.

​

This discussion is based upon provisions of the Code and U.S. Treasury regulations, rulings and judicial decisions thereunder as of the date hereof. Such authorities may be replaced, revoked or modified, possibly with retroactive effect, and which replacement, revocation, or modification could significantly affect the tax consequences described below. In addition, this discussion is based, in part, upon representations made by the depositary to us and assumes that the deposit agreement, and all other related agreements, will be performed in accordance with their terms. We have not sought any ruling from the IRS with respect to the statements made and the conclusions reached in the following discussion and there can be no assurance that the IRS or a court will agree with our statements and conclusions.

This discussion does not represent a detailed description of all of the United States federal income tax consequences applicable to particular United States Holders in light of individual circumstances, including to United States Holders in special tax situations such as:

​

•

a broker or dealer in stock, securities or currencies;

​

​

•

a bank and certain other financial institutions;

​

​

•

a regulated investment company;

​

​

•

a real estate investment trust;

​

​

•

an insurance company;

​

​

•

a tax-exempt organization;

​

​

•

a person holding the ADSs or ordinary shares as part of a hedging, integrated or conversion transaction, a constructive sale or a straddle;

​

​

•

a person that has elected the mark-to-market method of accounting for our securities;

​

​

•

a certain former citizen or resident of the United States subject to Section 877 of the Code;

​

​

•

an entity subject to the United States anti-inversion rules;

​

​

•

a person liable for alternative minimum tax;

​

46

TABLE OF CONTENTS

​

•

a person who owns or is deemed to own 10% or more of our total stock by vote or value;

​

​

•

a partnership or other pass-through entity for United States federal income tax purposes, or persons holding ordinary shares through such entities;

​

​

•

a person required to accelerate the recognition of any item of gross income with respect to the ADSs or ordinary shares as a result of such income being recognized on an applicable financial statement;

​

​

•

a person holding the ADSs or ordinary shares in connection with a permanent establishment or fixed base outside the United States; or

​

​

•

a person whose “functional currency” is not the United States dollar.

​

If a partnership (or other entity treated as a partnership for United States federal income tax purposes) holds the ADSs or ordinary shares, the tax treatment of a partner in such partnership will generally depend upon the status of the partner and the activities of such partnership. If the United States Holder is a partner of a partnership holding the ADSs or ordinary shares, such United States Holder should consult its tax advisors regarding the tax consequences of investing in and holding our ADSs or ordinary shares.

This discussion does not contain a detailed description of all the United States federal income tax consequences to United States Holders and does not address the Medicare tax on net investment income, any tax consequences arising in respect of the Foreign Account Tax Compliance Act, United States federal estate and gift taxes or the effects of any state, local or non-United States tax laws. United States Holders should consult their tax advisors concerning the particular United States federal tax consequences of the purchase, ownership and disposition of our ADSs or ordinary shares, as well as any consequences arising under the laws of any other taxing jurisdiction.

ADSs

A United States Holder of our ADSs, for United States federal income tax purposes, should generally be treated as the owner of the underlying ordinary shares that are represented by such ADSs. Accordingly, deposits or withdrawals of ordinary shares for ADSs generally are not expected to be subject to United States federal income tax. The remainder of this discussion assumes that a United States Holder of the ADSs will be treated in this manner. The U.S. Treasury has expressed concerns that intermediaries in the chain of ownership between the holder of an ADS and the issuer of the security underlying the ADS may be taking actions that are inconsistent with the beneficial ownership of the underlying security. Accordingly, the creditability of foreign taxes, if any, as described below, could be affected by actions taken by intermediaries in the chain of ownership between the holders of ADSs representing our ordinary shares and our company if, as a result of such actions, the holders of ADSs representing our ordinary shares are not properly treated as beneficial owners of the underlying ordinary shares.

Taxation of Dividends

Subject to the discussion under “— Passive Foreign Investment Company” below, the gross amount of distributions on the ADSs or ordinary shares to a United States Holder (including any amounts withheld to reflect PRC withholding taxes, as discussed above under “— People’s Republic of China Taxation”) will be taxable as dividends to the extent paid out of our current or accumulated earnings and profits, as determined under United States federal income tax principles. To the extent that the amount of any distribution exceeds our current and accumulated earnings and profits for a taxable year, the distribution will first be treated as a tax-free return of capital to a United States Holder, causing a reduction in the tax basis of the ADSs or ordinary shares, and to the extent the amount of the distribution exceeds such United States Holder’s tax basis, the excess will be taxed as capital gain recognized on a sale or exchange. We do not, however, expect to determine our earnings and profits in accordance with United States federal income tax principles. Therefore, United States Holders should expect that any distribution paid will generally be treated as a dividend for United States federal income tax purposes. Such dividends will not be eligible for the dividends received deduction allowed to corporations under the Code.

With respect to non-corporate United States Holders, certain dividends received from a “qualified foreign corporation” may qualify for reduced rates of taxation applicable to “qualified dividend income”. A non-United States corporation (other than a corporation that is a PFIC for the taxable year in which the dividend

47

TABLE OF CONTENTS

is paid or the preceding taxable year) will generally be treated as a “qualified foreign corporation” ​(a) with respect to dividends paid by that corporation on shares (or ADSs backed by such shares) that are readily tradable on an established securities market in the United States or (b) if such non-United States corporation is eligible for the benefits of a qualifying income tax treaty with the United States that includes an exchange of information program.

Under a published IRS Notice, ordinary shares are considered to be readily tradable on an established securities market in the United States if they are listed on the Nasdaq Global Market, as our ADSs are. Thus, we believe, but cannot guarantee, that dividends we pay on the ADSs will meet the conditions required for these reduced tax rates. Since our ordinary shares are not listed on an established securities market in the United States, we do not believe that dividends that we pay on our ordinary shares that are not represented by ADSs currently meet the conditions required for these reduced tax rates. There also can be no assurance that the ADSs will be considered readily tradable on an established securities market in the United States in later years. A qualified foreign corporation also includes a foreign corporation that is eligible for the benefits of certain income tax treaties with the United States. In the event that we are deemed to be a PRC resident enterprise under the Enterprise Income Tax Law, we may be eligible for the benefits of the Agreement Between the Government of the United States of America and the Government of the People’s Republic of China for the Avoidance of Double Taxation and the Prevention of Tax Evasion With Respect to Taxes on Income, or the Treaty, and if we are eligible for such benefits, dividends we pay on our ordinary shares, regardless of whether such shares are represented by ADSs, would be eligible for reduced rates of taxation, subject to applicable limitations. See “— People’s Republic of China Taxation” for further information on the Enterprise Income Tax Law.

Even if dividends would be treated as paid by a qualified foreign corporation, a non-corporate United States Holder will not be eligible for reduced rates of taxation if it does not hold our ADSs for more than 60 days during the 121-day period beginning 60 days before the ex-dividend date (disregarding certain periods of ownership while the United States Holder’s risk of loss is diminished) or if such United States Holder elects to treat the dividend income as “investment income” pursuant to Section 163(d)(4) of the Code. In addition, the rate reduction will not apply to dividends of a qualified foreign corporation if the non-corporate United States Holder receiving such dividend is obligated to make related payments with respect to positions in substantially similar or related property. This disallowance applies even if the minimum holding period has been met. Non-corporate United States Holders will not be eligible for reduced rates of taxation on any dividends received from us if we are a passive foreign investment company in the taxable year in which such dividends are paid or in the preceding taxable year. See “— Passive Foreign Investment Company” below.

Subject to the various limitations and disallowance rules that apply to foreign tax credits generally (including a minimum holding period requirement), any PRC withholding taxes on dividends may be treated as foreign taxes eligible for credit against a United States Holder’s United States federal income tax liability. For purposes of calculating the foreign tax credit, dividends paid on the ADSs or ordinary shares will be treated as income from sources outside the United States and will generally constitute passive category income. The rules governing the foreign tax credit are complex, and recently issued Treasury Regulations have introduced additional requirements and limitations to the foreign tax credit rules.

Each United States Holder should consult its tax advisors regarding the availability of the lower tax rates applicable to qualified dividend income for any dividends that we pay with respect to the ADSs or ordinary shares and the availability of any foreign tax credit, as well as the effect of any change in applicable law after the date of this prospectus.

Passive Foreign Investment Company

Based upon the market price of our ADSs, the value of our assets and the nature and composition of our income and assets, we do not believe that we were a PFIC for our taxable year ended December 31, 2025, although there can be no assurance in this regard. The IRS does not issue rulings with respect to PFIC status, and we cannot assure you that the IRS, or a court, will agree with any determination we make.

In general, we will be a PFIC for any taxable year if, after applying the applicable look-through rules, either:

​

•

at least 75% of our gross income is passive income; or

​

48

TABLE OF CONTENTS

​

•

at least 50% of the value of our assets (generally determined based on an average of the quarterly asset values for such year) is attributable to assets that produce or are held for the production of passive income.

​

For this purpose, passive income generally includes dividends, interest, income equivalent to interest, royalties and rents (other than royalties and rents derived in the active conduct of a trade or business and not derived from a related person). Cash and cash equivalents, securities held for investment purposes and certain other similar assets are generally, and cryptocurrency balances are likely, treated as an asset that produces or is held for the production of passive income. If we own at least 25% (by value) of the stock of another corporation, for purposes of determining whether we are a PFIC, we generally will be treated as owning our proportionate share of the other corporation’s assets and receiving our proportionate share of the other corporation’s income.

The determination of whether we are a PFIC is made annually. Accordingly, it is possible that we may become a PFIC in any future taxable year due to changes in our asset or income composition. Because we have valued our goodwill and other unbooked intangibles not reflected on our balance sheet based on the market value of the ADSs, a decrease in the price of the ADSs may also result in our becoming a PFIC. Furthermore, whether and to which extent our income and assets, including goodwill, will be characterized as active or passive will depend on various factors that are subject to uncertainty, including our future business plan and the application of laws that are subject to varying interpretation. For example, there is no authority that directly addresses the proper treatment of certain items of our income, such as income from cryptocurrency self-mining, hash rate sharing, or hosting for purposes of the PFIC rules and, although our company currently treats these items of income as active, such treatment is uncertain. Accordingly, there can be no assurances that we will not be a PFIC for any current or future taxable year, and our U.S. counsel expresses no opinion with respect to our PFIC status for any taxable year. If we are a PFIC for any taxable year during which a United States Holder holds the ADSs or ordinary shares, such United States Holder will be subject to special tax rules discussed below.

If we are a PFIC for any taxable year during which a United States Holder holds the ADSs or ordinary shares, absent certain elections (including a mark-to-market election, a qualified electing fund election and a deemed sale election, each as described below), such United States Holder will be subject to special tax rules with respect to any “excess distribution” received and any gain realized from a sale or other disposition, including a pledge, of ADSs or ordinary shares. Distributions received in a taxable year will be treated as excess distributions to the extent that they are greater than 125% of the average annual distributions received during the shorter of the three preceding taxable years or a United States Holder’s holding period in our ADSs or ordinary shares. Under these special tax rules:

​

•

the excess distribution and/or recognized gain will be allocated ratably over a United States Holder’s holding period for the ADSs or ordinary shares,

​

​

•

the amount of the excess distribution and/or recognized gain allocated to the current taxable year, and any taxable year prior to the first taxable year in which we were a PFIC, will be treated as ordinary income, and

​

​

•

the amount of the excess distribution and/or recognized gain allocated to each other taxable year will be subject to tax at the highest tax rate in effect for such year for individuals or corporations in the United States, as applicable, 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) from a sale or other disposition of the ADSs or ordinary shares cannot be treated as capital gains, even if a United States Holder holds the ADSs or ordinary shares as capital assets.

If we are a PFIC with respect to a United States Holder for any taxable year during such United States Holder’s holding period for our ADSs or ordinary shares and any of our non-U.S. subsidiaries that are corporations (or other corporations in which we directly or indirectly own equity interests) is also a PFIC, such United States Holder would generally be treated as owning a proportionate amount (by value) of the shares of each such non-U.S. entity that is a PFIC (each such corporation, a lower tier PFIC) for purposes of

49

TABLE OF CONTENTS

the application of these rules. United States Holders are strongly encouraged to consult their tax advisors regarding the application of the PFIC rules to any of our lower tier PFICs.

Deemed Sale Election

If we are a PFIC for any taxable year in which a United States Holder holds the ADSs or ordinary shares (unless such United States Holder makes a valid mark-to-market election as discussed below), such United States Holder will generally be subject to the special tax rules described above for that year and for each subsequent year in which such United States Holder holds the ADSs or ordinary shares even if we cease to be a PFIC in such subsequent years. However, if we cease to be a PFIC, a United States Holder may avoid the continuing impact of the PFIC rules by making a “deemed sale” election to recognize gain as if such United States Holder’s ADSs or ordinary shares had been sold for their fair market value on the last day of the last taxable year during which we were a PFIC (“Shares Deemed Sold”) and any gain from such deemed sale would be taxed as an “excess distribution” as described above. Any loss from the deemed sale is not recognized. For purposes of applying the PFIC rules, a new holding period for the Shares Deemed Sold will start on the day after the date of the deemed sale. After the deemed sale election, the United States Holder’s ADSs or ordinary shares that are Shares Deemed Sold will not be treated as shares in a PFIC unless we become a PFIC in a subsequent taxable year. United States Holders are urged to consult their tax advisors about a deemed sale election.

Mark-to-Market Election

As an alternative to the foregoing rules, a United States Holder of “marketable stock” in a PFIC may make a mark-to-market election with respect to such stock, provided that certain requirements are met. Our ADSs or ordinary shares generally will be treated as marketable stock if the ADSs or ordinary shares are “regularly traded” on a “qualified exchange or other market” ​(within the meaning of the applicable Treasury regulations). Our ADSs are currently listed on the Nasdaq Global Market which constitutes a qualified exchange, although there can be no assurance that the ADSs will be “regularly traded” for purposes of the mark-to-market election. Only the ADSs and not the ordinary shares are listed on the Nasdaq Global Market. Consequently, if a United States Holder is a holder of our ordinary shares that are not represented by our ADSs, such United States Holder generally will not be eligible to make a mark-to-market election.

If a United States Holder makes an effective mark-to-market election with respect to the ADSs it holds, for each taxable year that we are a PFIC, such United States Holder will include as ordinary income the excess of the fair market value of such ADSs held at the end of the taxable year over such United States Holder’s adjusted tax basis in such ADSs. A United States Holder will be entitled to deduct as an ordinary loss in each such taxable year the excess, if any, of its adjusted tax basis in the ADSs over the fair market value of such ADSs at the end of the taxable year, but only to the extent of the net amount previously included in income as a result of the mark-to-market election. A United States Holder’s adjusted tax basis in the ADSs will be increased by the amount of any income inclusion and decreased by the amount of any deductions under the mark-to-market rules. In addition, upon the sale or other disposition of our ADSs in a year that we are a PFIC, any gain will be treated as ordinary income and any loss will be treated as ordinary loss, but only to the extent of the net amount of previously included income as a result of the mark-to-market election.

If a United States Holder makes a mark-to-market election with respect to the ADSs it holds, it will be effective for the taxable year for which the election is made and all subsequent taxable years unless such ADSs are no longer regularly traded on a qualified exchange or other market, or the Internal Revenue Service consents to the revocation of the election. If a United States Holder makes a valid mark-to-market election and we cease to be a PFIC, the United States Holder will not be required to take into account the mark-to-market gain or loss described above during any period for which we are not a PFIC. United States Holders are urged to consult their tax advisors about the availability of the mark-to-market election, and whether making the election would be advisable in light of such United States Holder’s particular circumstances.

Qualified Election Fund Election

In certain circumstances, a shareholder in a PFIC may avoid some of the disadvantageous tax treatment described above by making a “qualified electing fund” election under Section 1295 of the Code. However, this

50

TABLE OF CONTENTS

option is not available to United States Holders because we do not intend to comply with the requirements necessary to permit United States Holders to make this election.

Reporting Requirements

For any taxable year for which we are a PFIC with respect to a United States Holder, such United States Holder will generally be required to file IRS Form 8621 regarding direct or indirect distributions received in respect of our ADSs or ordinary shares and any gain realized on the direct or indirect disposition of our ADSs or ordinary shares, and certain United States Holders will be required to file an annual information return (also on IRS Form 8621) relating to their ownership of our ADSs or ordinary shares. Significant penalties are imposed for failure to file such form. United States Holders are urged to consult their tax advisors concerning the United States federal income tax consequences of holding ADSs or ordinary shares if we are a PFIC in any taxable year.

Sale, Exchange or Other Taxable Disposition of our ADSs or Ordinary Shares

For United States federal income tax purposes, a United States Holder generally will recognize taxable gain or loss on any sale, exchange or other taxable disposition of the ADSs or ordinary shares in an amount equal to the difference between the amount realized for the ADSs or ordinary shares and the United States Holder’s tax basis in such ADSs or ordinary shares. Subject to the discussion under “— Passive Foreign Investment Company” above, such gain or loss will generally be capital gain or loss and will generally be long-term capital gain or loss if such United States Holder has held such ADSs or ordinary shares for more than one year. Long-term capital gains of non-corporate United States Holders (including individuals) generally are eligible for reduced rates of taxation. The deductibility of capital losses may be subject to limitations. Any gain or loss recognized by a United States Holder will generally be treated as United States source gain or loss for foreign tax credit limitation purposes, which may limit the availability of foreign tax credits. However, if (i) we are treated as a PRC resident enterprise for PRC tax purposes and PRC tax were imposed on any gain and (ii) a United States Holder is eligible for the benefits of the Treaty, such United States Holder may elect to treat such gain as PRC source gain under the Treaty for foreign tax credit purposes, subject to certain limitations. If such an election is made, the gain so treated will be treated as a separate class or “basket” of income for foreign tax credit purposes. United States Holders should consult their tax advisors regarding the proper treatment of gain or loss, as well as the availability of a foreign tax credit, in their particular circumstances.

Information Reporting and Backup Withholding

In general, information reporting will apply to dividends in respect of the ADSs or our ordinary shares and the proceeds from the sale, exchange or other disposition of the ADSs or our ordinary shares that are paid to a United States Holder within the United States (and in certain cases, outside the United States), unless a United States Holder is an exempt recipient. A backup withholding tax may apply to such payments if a United States Holder fails to provide a taxpayer identification number or certification of exempt status or fails to report in full dividend and interest income.

Backup withholding is not an additional tax and any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against a United States Holder’s United States federal income tax liability provided the required information is timely furnished to the IRS.

Specified Foreign Financial Assets

United States Holders who are individuals and certain domestic entities generally will be required to submit certain information to the IRS with respect to their beneficial ownership of our ADSs or ordinary shares as is necessary to identify the class or issue of which our ADSs or ordinary shares are a part. These requirements are subject to exceptions, including an exception for ADSs or ordinary shares held in accounts maintained by certain financial institutions and an exception applicable if the aggregate value of all “specified foreign financial assets” (as defined in the Code) does not exceed US$50,000. This law also imposes penalties if a United States Holder is required to submit such information to the IRS and fails to do so. United States Holders are urged to consult their tax advisors regarding the potential reporting requirements that may be imposed with respect to ownership of our ADSs or ordinary shares.

PLAN OF DISTRIBUTION

We may sell the securities offered through this prospectus (1) to or through underwriters or dealers, (2) directly to purchasers, including our affiliates, (3) through agents, or (4) through a combination of any these methods. The securities may be distributed at a fixed price or prices, which may be changed, market prices prevailing at the time of sale, prices related to the prevailing market prices, or negotiated prices. The prospectus supplement will describe the terms of the offering, including the following information, if applicable:

•

the name or names of any dealers or agents;

​

•

the name or names of any managing underwriter or underwriters;

​

•

the purchase price of the securities;

​

•

the net proceeds from the sale of the securities;

​

•

any delayed delivery arrangements;

​

•

any underwriting discounts, commissions and other items constituting underwriters’ compensation;

​

•

any offering price to the public;

​

•

any discounts or concessions allowed or reallowed or paid to dealers; and

​

•

any commissions paid to agents.

​

Sale through underwriters or dealers

If underwriters are used in the sale, the underwriters will acquire the securities for their own account, including through underwriting, purchase, security lending or repurchase agreements. The underwriters may resell the securities from time to time in one or more transactions, including negotiated transactions. Underwriters may sell the securities in order to facilitate transactions in any of our other securities (described in this prospectus or otherwise), including other public or private transactions and short sales. Underwriters may offer securities to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. Unless otherwise indicated in the prospectus supplement, the obligations of the underwriters to purchase the securities will be subject to certain conditions, and the underwriters will be obligated to purchase all the offered securities if they purchase any of them. The underwriters may change from time to time any public offering price and any discounts or concessions allowed or reallowed or paid to dealers. The prospectus supplement will include the names of the principal underwriters the respective amount of securities underwritten, the nature of the obligation of the underwriters to take the securities and the nature of any material relationship between an underwriter and us.

If dealers are used in the sale of securities offered through this prospectus, we will sell the securities to them as principals. They may then resell those securities to the public at varying prices determined by the dealers at the time of resale. The prospectus supplement will include the names of the dealers and the terms of the transaction.

Direct sales and sales through agents

We may sell the securities offered through this prospectus directly. In this case, no underwriters or agents would be involved. Such securities may also be sold through agents designated from time to time. The prospectus supplement will name any agent involved in the offer or sale of the offered securities and will describe any commissions payable to the agent by us. Unless otherwise indicated in the prospectus supplement, any agent will agree to use its reasonable best efforts to solicit purchases for the period of its appointment.

We may sell the securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act with respect to any sale of those securities. The terms of any such sales will be described in the prospectus supplement.

Delayed delivery contracts

If the prospectus supplement indicates, we may authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase securities at the public offering price under delayed delivery

52

TABLE OF CONTENTS

contracts. These contracts would provide for payment and delivery on a specified date in the future. The contracts would be subject only to those conditions described in the prospectus supplement. The applicable prospectus supplement will describe the commission payable for solicitation of those contracts.

Market making, stabilization and other transactions

Unless the applicable prospectus supplement states otherwise, each series of offered securities will be a new issue and will have no established trading market. We may elect to list any series of offered securities on an exchange. Any underwriters that we use in the sale of offered securities may make a market in such securities, but may discontinue such market making at any time without notice. Therefore, we cannot assure you that the securities will have a liquid trading market.

Any underwriter may also engage in stabilizing transactions, syndicate covering transactions and penalty bids in accordance with Rule 104 under the Exchange Act. Stabilizing transactions involve bids to purchase the underlying security in the open market for the purpose of pegging, fixing or maintaining the price of the securities. Syndicate covering transactions involve purchases of the securities in the open market after the distribution has been completed in order to cover syndicate short positions.

Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the securities originally sold by the syndicate member are purchased in a syndicate covering transaction to cover syndicate short positions. Stabilizing transactions, syndicate covering transactions and penalty bids may cause the price of the securities to be higher than it would be in the absence of the transactions. The underwriters may, if they commence these transactions, discontinue them at any time.

Derivative transactions and hedging

We, the underwriters or other agents may engage in derivative transactions involving the securities. These derivatives may consist of short sale transactions and other hedging activities. The underwriters or agents may acquire a long or short position in the securities, hold or resell securities acquired and purchase options or futures on the securities and other derivative instruments with returns linked to or related to changes in the price of the securities. In order to facilitate these derivative transactions, we may enter into security lending or repurchase agreements with the underwriters or agents. The underwriters or agents may effect the derivative transactions through sales of the securities to the public, including short sales, or by lending the securities in order to facilitate short sale transactions by others. The underwriters or agents may also use the securities purchased or borrowed from us or others (or, in the case of derivatives, securities received from us in settlement of those derivatives) to directly or indirectly settle sales of the securities or close out any related open borrowings of the securities.

Electronic auctions

We may also make sales through the Internet or through other electronic means. Since we may from time to time elect to offer securities directly to the public, with or without the involvement of agents, underwriters or dealers, utilizing the Internet or other forms of electronic bidding or ordering systems for the pricing and allocation of such securities, you should pay particular attention to the description of that system we will provide in a prospectus supplement.

Such electronic system may allow bidders to directly participate, through electronic access to an auction site, by submitting conditional offers to buy that are subject to acceptance by us, and which may directly affect the price or other terms and conditions at which such securities are sold. These bidding or ordering systems may present to each bidder, on a so-called “real-time” basis, relevant information to assist in making a bid, such as the clearing spread at which the offering would be sold, based on the bids submitted, and whether a bidder’s individual bids would be accepted, prorated or rejected. Of course, many pricing methods can and may also be used.

Upon completion of such an electronic auction process, securities will be allocated based on prices bid, terms of bid or other factors. The final offering price at which securities would be sold and the allocation of securities among bidders would be based in whole or in part on the results of the Internet or other electronic bidding process or auction.

The information incorporated by reference is considered to be a part of this prospectus 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 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 and information incorporated by reference in this prospectus, you should rely on the information contained in the document that was filed later.

INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 8.   INDEMNIFICATION OF DIRECTORS AND OFFICERS

The Cayman Companies Act does not limit the extent to which a company’s memorandum and articles of association may provide for indemnification of officers and directors, except to the extent any such provision may be held by the Cayman Islands courts to be contrary to public policy, such as to provide indemnification against dishonesty, willful default or fraud or the consequences of committing a crime. Our articles of association provide that we shall indemnify our officers and directors against all actions, proceedings, costs, charges, expenses, losses, damages or liabilities incurred or sustained by such directors or officer, other than by reason of such person’s dishonesty, willful default or fraud, in or about the conduct of our company’s business or affairs (including as a result of any mistake of judgment) or in the execution or discharge of his duties, powers, authorities or discretions, including without prejudice to the generality of the foregoing, any costs, expenses, losses or liabilities incurred by such director or officer in defending (whether successfully or otherwise) any civil proceedings concerning our company or its affairs in any court whether in the Cayman Islands or elsewhere. This standard of conduct is generally the same as permitted under the Delaware General Corporation Law for a Delaware corporation. In addition, we intend to enter into indemnification agreements with our directors and executive officers that will provide such persons with additional indemnification beyond that provided in our articles of association.

Under the indemnification agreements with our directors and executive officers, the form of which was filed as Exhibit 10.2 to our registration statement on Form F-1, as amended (File No. 333-234356), we have agreed to indemnify our directors and executive officers against certain liabilities and expenses incurred by such persons in connection with claims made by reason of their being such a director or executive officer.

Any underwriting agreement entered into in connection with an offering of our securities may also provide for indemnification of us and our officers and directors in certain cases.

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

We also maintain a directors and officers liability insurance policy for our directors and officers.

ITEM 9.   EXHIBITS

See Exhibit Index beginning on page II-4 of this registration statement.

ITEM 10.   UNDERTAKINGS.

(a)

The undersigned registrant hereby undertakes:

​

(1)   To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement.

(iii) Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

II-1

TABLE OF CONTENTS

(iv)   To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

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

(2)   That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3)   To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4)   To file a post-effective amendment to the registration statement to include any financial statements required by Item 8.A. of Form 20-F at the start of any delayed offering or throughout a continuous offering. Financial statements and information otherwise required by Section 10(a)(3) of the Securities Act need not be furnished, provided that the registrant includes in the prospectus, by means of a post-effective amendment, financial statements required pursuant to this paragraph (4) and other information necessary to ensure that all other information in the prospectus is at least as current as the date of those financial statements. Notwithstanding the foregoing, a post-effective amendment need not be filed to include financial statements and information required by Section 10(a)(3) of the Securities Act or Item 8.A of Form 20-F if such financial statements and information are contained in periodic reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this registration statement.

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

(i) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii)   Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(6)   That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities:

The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the

II-2

TABLE OF CONTENTS

following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i)   Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii)   Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii)   The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv)   Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b)   The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c)   Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
