BeyondSpring Inc.

We are a global clinical stage biopharmaceutical company focused on the development and commercialization of innovative cancer therapies. Our lead asset, Plinabulin, is being studied in late stage clinical trials for its potential benefit in the prevention of chemotherapy induced grade 4 neutropenia, or CIN, and as an anticancer agent in combination with docetaxel in advanced non-small cell lung cancer, or NSCLC. We are also investigating Plinabulin’s therapeutic potential in combination with various immuno-oncology indications. One indication is currently in two Phase 1/2 clinical trials of Plinabulin in combination with the immuno-oncology agent nivolumab. We also expect two investigator initiated trials in 2018, one in combination with programmed cell death protein 1, or PD-1 and CTLA-4 antibodies as a treatment for small cell lung cancer and the other in combination with pembrolizumab and platinum-based chemotherapy agents as a first-line treatment for NSCLC. We acquired global rights to Plinabulin in its entirety, including its Phase 2 clinical trial data, from Nereus Pharmaceuticals, Inc., or Nereus, and currently own global rights in all countries except for China and Hong Kong, where we own a 60% interest through our majority-owned Chinese subsidiary, Dalian Wanchunbulin Pharmaceuticals Ltd., or Wanchun Bulin, which holds 100% of the rights to Plinabulin in those geographic areas. We also own a 100% interest in a pipeline of preclinical immune-oncology product candidates that are in development as well as a ubiquitin-mediated degradation platform.

RISK FACTORS

Investing in our securities involves risks. Before making an investment decision, you should carefully consider the risks described below, on page 8 of the accompanying prospectus and under “Risk Factors” in our most recent annual report on Form 20-F or in any updates in each report on Form 6-K that indicates that it is being incorporated by reference, together with all of the other information appearing in this prospectus supplement or the accompanying prospectus or incorporated by reference herein or therein, including in light of your particular investment objectives and financial circumstances. In addition to those risk factors, there may be additional risks and uncertainties of which management is not aware or focused on, or that management deems immaterial. Our business, financial condition or results of operations could be materially adversely affected by any of these risks. The trading price of our securities could decline due to any of these risks, and you may lose all or part of your investment.

Risks Related to Our Ordinary Shares and this Offering

The trading prices of our ordinary shares are likely to be volatile, which could result in substantial losses to you.

The trading price of our ordinary shares is likely to be volatile and could fluctuate widely in response to a variety of factors, many of which are beyond our control. In addition, the performance and fluctuation of the market prices of other companies with business operations located mainly in China that have listed their securities in the United States may affect the volatility in the price of and trading volumes for our ordinary shares. Some of these companies have experienced significant volatility. The trading performances of these Chinese companies’ securities at the time of or after their offerings may affect the overall investor sentiment towards other Chinese companies listed in the United States and consequently may impact the trading performance of our ordinary shares.

In addition to market and industry factors, the price and trading volume for our ordinary shares may be highly volatile for specific business reasons, including:

announcements of regulatory approval or a complete response letter, or specific label indications or patient populations for its use, or changes or delays in the regulatory review process;

announcements of therapeutic innovations or new products by us or our competitors;

adverse actions taken by regulatory agencies with respect to our clinical trials, manufacturing supply chain or sales and marketing activities;

any adverse changes to our relationship with manufacturers or suppliers;

the results of our testing and clinical trials;

the results of our efforts to acquire or license additional product candidates;

variations in the level of expenses related to our existing product candidates or preclinical studies and clinical trials;

any intellectual property infringement actions in which we may become involved;

announcements concerning our competitors or the pharmaceutical industry in general;

achievement of expected product sales and profitability;

manufacturing, supply or distribution shortages;

variations in our results of operations;

S-5

Table of Contents

announcements about our earnings that are not in line with analyst expectations;

publication of operating or industry metrics by third parties, including government statistical agencies, that differ from expectations of industry or financial analysts;

research reports and changes in financial estimates by securities research analysts;

announcements made by us or our competitors of new product and service offerings, acquisitions, strategic relationships, joint ventures or capital commitments;

press reports, whether or not true, about our business;

additions to, or departures of, our management;

fluctuations of exchange rates between the RMB and the U.S. dollar;

release or expiry of lock-up or other transfer restrictions on our outstanding ordinary shares;

sales or perceived potential sales of additional ordinary shares;

sales of our ordinary shares by us, our executive officers and directors or our shareholders in the future;

general economic and market conditions and overall fluctuations in the U.S. equity markets;

changes in accounting principles; and

changes or developments in the Chinese or global regulatory environment.

Any of these factors may result in large and sudden changes in the volume and trading price of our ordinary shares. In the past, following periods of volatility in the market price of a company’s securities, shareholders have often instituted securities class action litigation against that company. If we are involved in a class action suit, it could divert the attention of management, and, if adversely determined, have a material adverse effect on our financial condition and results of operations.

In addition, the stock market, in general, and small pharmaceutical and biotechnology companies have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of these companies. Broad market and industry factors may negatively affect the market price of our ordinary shares, regardless of our actual operating performance. Further, factors related to financial markets beyond our control may cause our ordinary shares price to decline rapidly and unexpectedly.

Sales or the availability for sales of substantial amounts of our ordinary shares in the public market could cause the price of our ordinary shares to decline significantly.

Sales of our ordinary shares or other equity securities in the public market after this offering, or the perception that these sales could occur, could cause the market price of our ordinary shares to decline significantly. Immediately after this offering, we will have 23,174,797 ordinary shares outstanding. All ordinary shares sold in this offering will be freely transferable by persons other than our “affiliates” without restriction or additional registration. As of December 31, 2017, we had 22,530,702 ordinary shares outstanding. Of these shares, 174,286 ordinary shares have been registered under the Securities Act of 1933, as amended, or the Securities Act, and are freely transferable by persons other than our “affiliates” without restriction or additional registration; the remaining shares outstanding have not been registered under the Securities Act and may be offered or sold only pursuant to an effective registration statement or pursuant to an available exemption from the registration requirements. If these shares are sold, or if it is perceived that they will be sold, in the public market, the trading price of our ordinary shares could decline.

S-6

Table of Contents

NPBISPO Liquidating Trust, or the Nereus Trust, a holder of our ordinary shares, has the right to cause us to register under the Securities Act the sale of its shares. Registration of these shares under the Securities Act would result in ordinary shares representing these shares becoming freely tradable without restriction under the Securities Act immediately upon the effectiveness of the registration. Sales of these registered shares in the public market could cause the price of our ordinary shares to decline significantly.

We have broad discretion to determine how to use the funds raised in this offering, and may use them in ways that may not enhance our operating results or the price of our ordinary shares.

Our management will have broad discretion over the use of proceeds from this offering, and we could spend the proceeds from this offering in ways our shareholders may not agree with or that do not yield a favorable return, if at all. We intend to use the net proceeds of this offering for general corporate purposes. However, our use of these proceeds may differ substantially from our current plans. You will be relying on the judgment of our management with regard to the use of these net proceeds, and you will not have the opportunity to assess whether the proceeds are being used in ways with which you would agree. It is possible that the net proceeds will be invested in a way that does not yield a favorable, or any, return for us. The failure of our management to use such funds effectively could have a material adverse effect on our business, financial condition, operating results and cash flow. See “Use of Proceeds.”

Because we do not expect to pay dividends in the foreseeable future, you must rely on price appreciation of the ordinary shares for return on your investment.

We intend to retain most, if not all, of our available funds and earnings to fund the development and growth of our business. As a result, we do not expect to pay any cash dividends in the foreseeable future. Therefore, you should not rely on an investment in our ordinary shares as a source for any future dividend income.

Our board of directors has significant discretion as to whether to distribute dividends. Our shareholders may, by ordinary resolution, declare dividends, but no dividend shall exceed the amount recommended by our board of directors. Even if our board of directors decides to declare and pay dividends, the timing, amount and form of future dividends, if any, will depend on, among other things, our future results of operations and cash flow, our capital requirements and surplus, the amount of distributions, if any, received by us from our subsidiaries, our financial condition, contractual restrictions and other factors deemed relevant by our board of directors. Accordingly, the return on your investment in our ordinary shares will likely depend entirely upon any future price appreciation of the ordinary shares. Our ordinary shares may not appreciate in value or even maintain the price at which you purchased the ordinary shares. You may not realize a return on your investment in the ordinary shares, and you may even lose your entire investment in the ordinary shares.

You will experience immediate and substantial dilution after giving effect to the net proceeds from this offering.

If you purchase ordinary shares in this offering, you will pay more for your ordinary shares than the amount paid by existing shareholders for their ordinary shares on a per ordinary share basis. As a result, you will experience immediate and substantial dilution of $25.01 per ordinary share, representing the difference between our as adjusted net tangible book value per ordinary share as of December 31, 2017, the issuance and sale of ordinary shares in this offering and the offering price of $27.06 per ordinary share, as set forth on the cover page of this prospectus. In addition, you may experience further dilution to the extent that we make any grants of equity-based awards.

DIVIDEND POLICY

We have never declared or paid cash dividends to our shareholders, and we do not intend to pay cash dividends in the foreseeable future. We intend to reinvest any earnings in developing and expanding our business. Any future determination relating to our dividend policy will be at the discretion of our board of directors and will depend on a number of factors, including future earnings, our financial condition, operating results, contractual restrictions, capital requirements, business prospects, our strategic goals and plans to expand our business, applicable law and other factors that our board of directors may deem relevant.

See “Risk Factors—Risks Related to Our Ordinary Shares and This Offering—Because we do not expect to pay dividends in the foreseeable future, you must rely on price appreciation of the ordinary shares for return on your investment.”

We are a holding company incorporated in the Cayman Islands. We will rely to some extent on dividends from our U.S., Australia and PRC subsidiaries for payment of any dividends to our shareholders. PRC regulations may restrict the ability of our PRC subsidiaries to make such dividend payments to us. See “Risk Factors—Risks Related to Our Doing Business in China—In the future, we may rely to some extent on dividends and other distributions on equity from our principal operating subsidiaries to fund offshore cash and financing requirements” and “Business—Government Regulation—Chinese Regulation—Regulations of Dividend Distribution” in our most recent annual report on Form 20-F, incorporated herein by reference.

DILUTION

If you invest in our ordinary shares in this offering, your interest will be diluted to the extent of the difference between the offering price per ordinary share and the as adjusted net tangible book value per ordinary share immediately after this offering.

As of December 31, 2017, our net tangible book value was approximately $28.03 million, or $1.24 per ordinary share. Our net tangible book value represents our total tangible assets less our total liabilities. Our net tangible book value per ordinary share is our net tangible book value divided by the number of ordinary shares outstanding as of December 31, 2017.

After giving effect to our issuance and sale of 739,095 ordinary shares in this offering at an offering price of $27.06 per ordinary share, as set forth on the cover page of this prospectus, and after deducting estimated offering expenses payable by us, our as adjusted net tangible book value as of December 31, 2017 would have been $47.72 million, or $2.05 per ordinary share. This amount represents an immediate increase in as adjusted net tangible book value of $0.81 per ordinary share to existing shareholders and an immediate dilution in net tangible book value of $25.01 per ordinary share to investors purchasing ordinary shares in this offering, as illustrated in the following table:

Offering price per share			$	27.06
Historical net tangible book value per share as of December 31, 2017	$	1.24
Increase in net tangible book value per share attributable to investors in this offering	$	0.81
As adjusted net tangible book value per share after offering			$	2.05
Dilution in net tangible book value per share to new investors			$	25.01

The number of ordinary shares shown as issued and outstanding above as of December 31, 2017 does not include (i) 263,162 unvested restricted shares (of which 163,162 were subject to time-based vesting and 100,000 were subject to performance-based vesting); (ii) 343,000 options, of which 0 were vested and 343,000 were unvested (with a weighted average exercise price of $29.00 per share) (of which 283,000 were subject to time-based vesting and 60,000 were subject to performance-based vesting); and (iii) 600,000 in other stock-based awards, all unvested and subject to performance-based vesting, under the 2017 Omnibus Incentive Plan, or our 2017 Incentive Plan.

To the extent that any additional equity awards are granted under our 2017 Incentive Plan in the future, you will experience further dilution. In addition, we may choose to raise additional capital due to market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of these securities may result in further dilution to our shareholders.

ENFORCEABILITY OF CIVIL LIABILITIES

We are incorporated under the laws of the Cayman Islands as an exempted company with limited liability. We incorporated in the Cayman Islands because of certain benefits associated with being a Cayman Islands corporation, 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 have a less developed body of securities laws that provide significantly less protection to investors as compared to the securities laws of the United States. In addition, Cayman Islands companies may not have standing to sue before the federal courts of the United States.

A portion of our assets, including certain Chinese patents, are located in China. In addition, some 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 our directors and officers, 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.

Maples and Calder (Hong Kong) LLP, our counsel as to Cayman Islands law, and Han Kun Law Offices, our counsel as to Chinese law, have respectively advised us that there is uncertainty as to whether the courts of the Cayman Islands or China would, respectively, (1) recognize or enforce judgments of United States courts obtained against us or our directors or officers predicated upon the civil liability provisions of the securities laws of the United States or any state in the United States or (2) entertain original actions brought in the Cayman Islands or China against us or our directors or officers predicated upon the securities laws of the United States or any state in the United States. Furthermore, Maples and Calder (Hong Kong) LLP and Han Kun Law Offices have advised us that, as of the date of this prospectus, no treaty or other form of reciprocity exists between the Cayman Islands and China governing the recognition and enforcement of judgments.

Maples and Calder (Hong Kong) LLP has further advised us that although there is no statutory enforcement in the Cayman Islands of judgments obtained in the United States or China, 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 (1) is given by a foreign court of competent jurisdiction, (2) imposes on the judgment debtor a liability to pay a liquidated sum for which the judgment has been given, (3) is final, (4) is not in respect of taxes, a fine or a penalty, (5) 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, (6) not inconsistent with a Cayman Islands judgement in respect of the same matter and (7) not impeachable on the grounds of fraud. A Cayman Islands Court may stay enforcement proceedings if concurrent proceedings are being brought elsewhere.

Han Kun Law Offices has advised us that the recognition and enforcement of foreign judgments are provided for under the PRC Civil Procedure Law. Chinese 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. Han Kun Law Offices has advised us further that under Chinese law, courts in China 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 Chinese law or national sovereignty, security or social public interest. As there exists 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 Chinese 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.

OUR COMPANY

We are a global clinical stage biopharmaceutical company focused on the development and commercialization of innovative cancer therapies. Our lead asset, Plinabulin, is being studied in late stage clinical trials for its potential benefit in the prevention of chemotherapy induced grade 4 neutropenia, or CIN, and as an anticancer agent in combination with docetaxel in advanced non-small cell lung cancer, or NSCLC. We are also investigating Plinabulin’s therapeutic potential in combination with various immuno-oncology indications. One indication is currently in two Phase 1/2 clinical trials of Plinabulin in combination with the immuno-oncology agent nivolumab. We also expect two investigator initiated trials in 2018, one in combination with programmed cell death protein 1, or PD-1 and CTLA-4 antibodies as a treatment for small cell lung cancer and the other in combination with pembrolizumab and platinum-based chemotherapy agents as a first-line treatment for NSCLC. We acquired global rights to Plinabulin in its entirety, including its Phase 2 clinical trial data, from Nereus Pharmaceuticals, Inc., or Nereus, and currently own global rights in all countries except for China and Hong Kong, where we own a 60% interest through our majority-owned Chinese subsidiary, Dalian Wanchunbulin Pharmaceuticals Ltd., which holds 100% of the rights to Plinabulin in those geographic areas. We also own a 100% interest in a pipeline of preclinical immune-oncology product candidates that are in development as well as a ubiquitin-mediated degradation platform.

CAPITALIZATION

DESCRIPTION OF SHARE CAPITAL

We are a Cayman Islands exempted company with limited liability and our affairs are governed by our memorandum and articles of association, as amended and restated from time to time and the Companies Law (2018 Revision) of the Cayman Islands, which is referred to as the Companies Law below, and the common law of the Cayman Islands.

As of March 30, 2018, our authorized share capital was $50,000, consisting of 500,000,000 ordinary shares, par value of U.S. $0.0001, each. As of March 30, 2018, 22,455,702 ordinary shares issued and outstanding. All of our issued and outstanding ordinary shares are fully paid.

Table of Contents

The following are summaries of material provisions of our current amended and restated memorandum and articles of association that became effective immediately prior to the completion of our initial public offering, or IPO, in March 2017, insofar as they relate to the material terms of our ordinary shares.

Objects of Our Company

Under our amended and restated memorandum and articles of association, the objects of our Company are unrestricted and we have the full power and authority to carry out any object not prohibited by the law of the Cayman Islands.

Ordinary Shares

Our ordinary shares are issued in registered form and are issued when registered in our register of members. Our shareholders who are non-residents of the Cayman Islands may freely hold and vote their 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 by ordinary resolution declare a dividend, but no dividend may exceed the amount recommended by our directors. Under Cayman Islands law, dividends may be declared and paid only out of funds legally available therefor, namely out of either profit or our 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

Voting at any shareholders’ meeting is by show of hands unless a poll is demanded. A poll may be demanded by the chairman of such meeting or any one or more shareholders who together hold not less than 10% of the voting share capital of our Company present in person or by proxy.

A quorum required for a meeting of shareholders consists of one or more shareholders present and holding not less than a majority of all voting share capital of our Company in issue. Shareholders may be present in person or by proxy or, if the shareholder is a legal entity, by its duly authorized representative. Shareholders’ meetings may be convened by our board of directors on its own initiative or upon a request to the directors by shareholders holding at the date of deposit of the requisition not less than ten percent of our voting share capital in issue. Advance notice of at least seven calendar days is required for the convening of our annual general shareholders’ meeting and any other general shareholders’ meeting.

An ordinary resolution to be passed at a meeting by the shareholders requires the affirmative vote of a simple majority of the votes attaching to the ordinary shares cast at a meeting, while a special resolution requires the affirmative vote of no less than two-thirds of the votes attaching to the ordinary shares cast at a meeting. Both ordinary resolutions and special resolutions may also be passed by a unanimous written resolution signed by all the shareholders of our Company, as permitted by the Companies Law and our amended and restated memorandum and articles of association. A special resolution will be required for important matters such as a change of name or making changes to our amended and restated memorandum and articles of association. Holders of the ordinary shares may, among other things, divide or combine their shares by ordinary resolution.

Transfer of Ordinary Shares

Subject to the restrictions set out below, any of our shareholders may transfer all or any of his or her ordinary shares by an instrument of transfer in the usual or common form or any other form approved by our board of directors.

Our board of directors may, in its absolute discretion, decline to register any transfer of any ordinary share which is not fully paid up or on which we have a lien. Our board of directors may also decline to register any transfer of any ordinary share unless:

Table of Contents

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 shares;

the instrument of transfer is properly stamped, if required;

in the case of a transfer to joint holders, the number of joint holders to whom the ordinary share is to be transferred does not exceed four; and

a fee of such maximum sum as the NASDAQ Capital Market may determine to be payable or such lesser sum as our directors may from time to time require is paid to us in respect thereof.

If our board of directors refuse to register a transfer they shall, within two months after the date on which the instrument of transfer was lodged, send to each of the transferor and the transferee notice of such refusal.

The registration of transfers may, after compliance with any notice required of the NASDAQ Capital Market, be suspended and the register closed at such times and for such periods as our board of directors may from time to time determine, provided, however, that the registration of transfers shall not be suspended nor the register closed for more than 30 days in any year as our board of directors may determine.

Liquidation

On a return of capital on winding up or otherwise (other than on conversion, redemption or purchase of shares), assets available for distribution among the holders of ordinary shares shall be distributed among the holders of our ordinary shares on a pro rata basis. If our assets available for distribution are insufficient to repay all of the paid-up capital, the assets will be distributed so that the losses are borne by our shareholders proportionately.

Calls on Shares and Forfeiture of Shares

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

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. Our Company may also repurchase any of our shares (including any redeemable shares) provided that the manner and terms of such purchase have been approved by our board of directors or by ordinary resolution of our shareholders, or are otherwise authorized by our amended and restated memorandum and articles of association. Under the Companies Law, the redemption or repurchase of any share may be paid out of the company’s profits or out of the proceeds of a fresh 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 the company can, immediately following such payment, pay its debts as they fall due in the ordinary course of business. In addition, under the Companies Law 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.

Variations of Rights of Shares

The rights attached to any class or series of shares (unless otherwise provided by the terms of issue of the shares of that class or series) may, subject to our amended and restated memorandum and articles of association, be varied with the consent in writing of the holders of not less than two thirds of the issued shares of that class or series or with the sanction of a special resolution passed at a general meeting of the holders of the shares of that class or series. The rights conferred upon the holders of the shares of any class issued shall not, unless otherwise expressly provided by the terms of issue of the shares of that class, be deemed to be varied by the creation or issue of further shares ranking pari passu with such existing class of shares.

Table of Contents

Issuance of Additional Shares

Our amended and restated memorandum and articles of association authorize our board of directors to issue additional ordinary shares from time to time as our board of directors shall determine, to the extent of available authorized but unissued shares.

Our amended and restated memorandum and articles of association also authorize our board of directors to establish from time to time one or more series of preferred shares and to determine, with respect to any series of preferred shares, the terms and rights of that series, including:

the designation of the series;

the number of shares of the series;

the dividend rights, dividend rates, conversion rights, voting rights; and

the rights and terms of redemption and liquidation preferences.

Our board of directors may issue preferred shares without action by our shareholders to the extent authorized but unissued. Issuance of these shares may dilute the voting power of holders of ordinary shares.

Inspection of Books and Records

Holders of our ordinary shares will have no general right under Cayman Islands law to inspect or obtain copies of our list of shareholders or our corporate records. However, we will provide our shareholders with annual audited financial statements. See “Where You Can Find Additional Information.”

Anti-Takeover Provisions

Some provisions of our amended and restated memorandum and articles of association may discourage, delay or prevent a change of 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; and

limit the ability of shareholders to requisition and convene general meetings of shareholders.

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

General Meetings of Shareholders and Shareholder Proposals

Our shareholders’ general meetings may be held in such place within or outside the Cayman Islands as our board of directors considers appropriate.

As a Cayman Islands exempted company, we are not obliged by the Companies Law to call shareholders’ annual general meetings. Our amended and restated memorandum and articles of association provide that we may (but are not obliged to) hold a general meeting in each year as our annual general meeting.

Shareholders’ annual general meetings and any other general meetings of our shareholders may be convened by a majority of our board of directors. Our board of directors shall give not less than seven calendar days’ written notice of a shareholders’ meeting to those persons whose names appear as members in our register of members on the date the notice is given (or on any other date determined by our directors to be the record date for such meeting) and who are entitled to vote at the meeting.

Table of Contents

Cayman Islands law 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 amended and restated memorandum and articles of association allow our shareholders holding shares representing in aggregate not less than ten percent of our voting share capital in issue, to requisition an extraordinary general meeting of our shareholders, in which case our directors are obliged to call such meeting and to put the resolutions so requisitioned to a vote at such meeting; however, our amended and restated memorandum and 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.

Exempted Company

We are an exempted company with limited liability under the Companies Law. The Companies Law 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 that an exempted company:

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

is not required to open its register of members for inspection;

does not have to hold an annual general meeting;

may issue negotiable or bearer shares or shares with no par value;

may obtain an undertaking against the imposition of any future taxation (such undertakings are usually given for 20 years in the first instance);

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

may register as a limited duration company; and

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 the 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).

Under Cayman Islands law, we must keep a register of members and there should be entered therein:

the names and addresses of the members, a statement of the shares held by each member, and of the amount paid or agreed to be considered as paid, on the shares of each member;

the date on which the name of any person was entered on the register as a member; and

the date on which any person ceased to be a member.

Under Cayman Islands law, the register of members of our Company is prima facie evidence of the matters set out therein (i.e. the register of members will raise a presumption of fact on the matters referred to above unless rebutted) and a member registered in the register of members should be deemed as a matter of Cayman Islands law to have legal title to the shares as set against its name in the register of members. Once our register of members has been updated, the shareholders recorded in the register of members should be deemed to have legal title to the shares set against their name.

Table of Contents

If the name of any person is incorrectly entered in, or omitted from, our register of members, or if there is any default or unnecessary delay in entering on the register the fact of any person having ceased to be a member of our company, the person or member aggrieved (or any member of our Company or our Company itself) may apply to the Cayman Islands Grand Court for an order that the register be rectified, and the Court may either refuse such application or it may, if satisfied of the justice of the case, make an order for the rectification of the register.

History of Securities Issuances

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

On July 20, 2015 we issued 300,000 ordinary shares to Wanchun Biotech in exchange for 100% equity interest in Wanchun Biotechnology Limited, the immediate parent of BeyondSpring U.S., in which Wanchun Biotech had previously invested $3,000,000.

On September 14, 2016, we issued 1,129,628 ordinary shares pursuant to Series B round of ordinary shares financing for aggregate cash consideration of $15,250,000.

On March 14, 2017, we completed our IPO on the NASDAQ Capital Market pursuant to which we issued 174,286 ordinary shares at $20.00 per ordinary share for gross proceeds of $3,486,000. In conjunction with our IPO, we issued 2,541,048 ordinary shares in a private placement to certain investors at $20.00 per ordinary share for gross proceeds of $50,821,000. Immediately prior to our IPO, we issued 2,112,963 ordinary shares to NPBSIPO Liquidating Trust, or Nereus Trust, in exchange for the termination of the relevant royalty payment arrangements with the seller of the patent of Plinabulin.

In connection with our initial public offering, we adopted the 2017 Omnibus Incentive Plan, or our 2017 Incentive Plan, to provide additional incentives to selected directors, officers, employees and consultants, and to enable our Company to obtain and retain the services of these individuals. The 2017 Incentive Plan enables us to grant options, restricted shares or other awards to our directors, employees and consultants. We authorized 2,137,037 ordinary shares to be available for grant pursuant to awards under the 2017 Incentive Plan, and as of March 30, 2018, there were 416,260 shares remaining available for grant. As of March 30, 2018, there were the following outstanding awards under the 2017 Incentive Plan: (i) 243,162 unvested restricted shares (of which 143,162 were subject to time-based vesting and 100,000 were subject to performance-based vesting); (ii) 373,000 options, of which 283,000 were vested (with a weighted average exercise price of $29 per share) and 90,000 were unvested (with a weighted average exercise price of $28.43 per share) (of which 75,500 were subject to time-based vesting and 14,500 were subject to performance-based vesting); and (iii) 600,000 in other stock-based awards, all unvested and subject to performance-based vesting.

Differences in Corporate Law

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

Mergers and Similar Arrangements

The Companies Law permits mergers and consolidations between Cayman Islands companies and between Cayman Islands companies and 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 combined 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 written plan of merger or consolidation must be filed with the Registrar of Companies together with a declaration as to the solvency of the consolidated or surviving company, a declaration as to 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. Dissenting shareholders have the right to be paid the fair value of their shares (which, if not agreed between the parties, will be determined by the Cayman Islands court) if they follow the required procedures, subject to certain exceptions. Court approval is not required for a merger or consolidation which is effected in compliance with these statutory procedures.

Table of Contents

In addition, there are statutory provisions that facilitate the reconstruction and amalgamation of companies, provided that the arrangement is approved by a majority in number of each class of shareholders or creditors with whom the arrangement is to be made, and who must in addition represent three-fourths in value of each such class of shareholders or creditors, as the case may be, that are present and voting either in person or by proxy at a meeting, or meetings, convened for that purpose. The convening of the 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 Grand 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 Companies Law.

When a takeover offer is made and accepted by holders of 90% of the shares affected within four months, 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 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 is thus approved, the dissenting shareholder would have no rights comparable to appraisal rights, 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 a derivative action may ordinarily not be brought by a minority shareholder. However, based on English authority, which would in all likelihood be of persuasive authority in the Cayman Islands, the Cayman Islands courts can be expected (and have had occasion) to follow and apply the common law principles (namely the rule in Foss v. Harbottle and the exceptions thereto) so that a minority shareholder may be permitted to commence a representative action against, or derivative actions in the name of, our Company to challenge:

an act which is ultra vires the company or illegal and is therefore incapable of ratification by the shareholders,

an act which constitutes a fraud against the minority where the wrongdoers are themselves in control of the company, or

an act which requires a resolution with a qualified (or special) majority (i.e. more than a simple majority) which has not been obtained.

Table of Contents

Indemnification of Directors and Executive Officers and Limitation of Liability

Cayman Islands law 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 civil fraud or the consequences of committing a crime. Our amended and restated memorandum and articles of association require us to indemnify every director, alternate director, secretary, assistant secretary, or other officer for the time being and from time to time of our Company (but not including our auditors) and the personal representatives of the same against all actions, proceedings, costs, charges, expenses, losses, damages or liabilities incurred or sustained by such indemnified person, other than by reason of such indemnified person’s own 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 indemnified person in defending (whether successfully or otherwise) any civil proceedings concerning us or our 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 have entered into indemnification agreements with each of our directors and executive officers that provide such persons with additional indemnification beyond that provided in our amended and restated memorandum and 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.

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 act 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 reasonably believes to be in the best interests of the corporation. He must not use his corporate position for personal gain or advantage. This duty prohibits self-dealing by a director and mandates that the best interest of the corporation and its shareholders take precedence over any interest possessed by a director, officer or controlling shareholder and not shared by 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, the 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 in good faith in the best interests of the company, a duty not to make a personal profit based on his 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 personal interest or his 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 duties a greater degree of skill than may reasonably be expected from a person of his 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 Action by Written Consent

Under the Delaware General Corporation Law, a corporation may eliminate the right of shareholders to act by written consent by amendment to its certificate of incorporation. Cayman Islands law and our amended and restated articles of association provide that shareholders may approve corporate matters by way of a unanimous written resolution signed by or on behalf of each shareholder who would have been entitled to vote on such matter at a general meeting without a meeting being held.

Table of Contents

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. 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.

Cayman Islands law 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 articles of association. Our amended and restated articles of association allow our shareholders holding not less than ten percent of all voting power of our share capital in issue to requisition a shareholder’s meeting, in which case our board of directors is obliged to call such meeting and to put the resolutions so requisitioned to a vote at such meeting. Other than this right to requisition a shareholders’ meeting, our amended and restated articles of association do not provide our shareholders other right to put proposal before a meeting. As an exempted Cayman Islands company, we are not obliged 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. There are no prohibitions in relation to cumulative voting under the laws of the Cayman Islands but our amended and restated articles of association do not provide for cumulative voting. As a result, our shareholders are not afforded any less 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 amended and restated articles of association, directors may be removed with or without cause, by an ordinary resolution of our shareholders.

Transactions with Interested Shareholders

The Delaware General Corporation Law contains a business combination statute applicable to Delaware corporations whereby, unless the corporation has specifically elected not to be governed by such statute by amendment to its certificate of incorporation, 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 who, or a group which, owns or owned 15% or more of the target’s outstanding voting share 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.

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, it does provide that such transactions must be entered into bona fide in the best interests of the company and for a proper purpose and not with the effect of constituting a fraud on the minority shareholders.

Table of Contents

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 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.

Under Cayman Islands law, a company may be wound up by either an order of the courts of the Cayman Islands or by a special resolution of its members or, if the company is unable to pay its debts as they fall due, by an ordinary resolution of its members. 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. Under the Companies Law and our amended and restated articles of association, our Company may be dissolved, liquidated or wound up by a special resolution of our shareholders, or by an ordinary resolution on the basis that our Company is unable to pay its debts as they fall due.

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 Cayman Islands law and our amended and restated articles of association, if our share capital is divided into more than one class of shares, we may vary the rights attached to any class with the written consent of the holders of not less than two thirds of the issued shares of that class or with the sanction of a special resolution passed at a general meeting of the holders of the shares of that class.

Amendment of Governing Documents

Under the Delaware General Corporation Law, a corporation’s governing documents may be amended with the approval of a majority of the outstanding shares entitled to vote, unless the certificate of incorporation provides otherwise. Under Cayman Islands law, our amended and restated memorandum and articles of association may only be amended with a special resolution of our shareholders.

Rights of Non-resident or Foreign Shareholders

There are no limitations imposed by our amended and restated memorandum and 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 amended and restated memorandum and articles of association governing the ownership threshold above which shareholder ownership must be disclosed.

Registration Rights

On January 30, 2013, Wanchun Biotech and Nereus entered into an asset purchase agreement, wherein Wanchun Biotech purchased certain intellectual property rights to Plinabulin, in exchange for certain royalty payments. Nereus was dissolved in February 2013. In connection with the termination of the asset purchase agreement, BeyondSpring Inc. entered into a termination agreement, or the Termination Agreement, with Wanchun Biotech and Nereus (which was executed by Fortis Advisors LLC in an administrative capacity as an agent of Nereus), on February 2, 2015. Pursuant to the Termination Agreement, the Nereus Trust is entitled to demand rights with respect to the registration of up to 2,112,963 shares under the Securities Act. Under the terms of the Termination Agreement, we will be required, upon demand, to file a registration statement covering the shares requested to be registered for public resale and use our commercially reasonable efforts to effect the registration of such shares. We are required to effect only one registration pursuant to this provision of the Termination Agreement. A demand for registration may be made any time following March 14, 2018. The shares held by Nereus Trust will cease to be entitled to registration rights (i) upon the sale of any such shares in a registered offering or pursuant to Rule 144 under the Securities Act or (ii) if such shares are eligible to be sold without restrictions pursuant to Rule 144 under the Securities Act.

PLAN OF DISTRIBUTION

We may sell or distribute our ordinary shares from time to time in one or more public or private transactions:

through underwriters;

through agents;

to dealers;

directly to one or more purchasers;

in “at the market” offerings, within the meaning of Rule 415(a)(4) of the Securities Act, to or through a market maker or into an existing trading market on an exchange or otherwise;

in block trades;

through a combination of any of the above; and

any other method permitted pursuant to applicable law.

Any sale or distribution may be effected by us:

at market prices prevailing at the time of sale;

at varying prices determined at the time of sale; or

at negotiated or fixed prices.

At any time a particular offer of the ordinary shares is made, a prospectus supplement, if required, will be distributed and set forth the terms of each specific offering, including the name or names of any underwriters or agents, the purchase price of the ordinary shares and the proceeds to us from such sales or distribution, any delayed delivery arrangements, any underwriting discounts and other items constituting underwriters’ compensation, any initial public offering price and any discounts or concessions allowed or re-allowed or paid to dealers. Any initial public offering price and any discounts or concessions allowed or re-allowed or paid to dealers may be changed from time to time.

In compliance with certain guidelines of FINRA, with respect to shelf registration statements, the maximum commission or discount to be received by any FINRA member or independent broker-dealer may not exceed 8% of the aggregate amount of securities offered pursuant to this prospectus and any applicable prospectus supplement.

In addition, we may distribute the ordinary shares as a dividend or in a rights offering to our existing security holders. In some cases, we or dealers acting for us or on behalf of us may also repurchase the ordinary shares and reoffer them to the public by one or more of the methods described above.

Through Underwriters

If underwriters are used in a sale or distribution, the ordinary shares will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The ordinary shares may be offered to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. The underwriter or underwriters with respect to a particular underwritten offering and, if an underwriting syndicate is used, the managing underwriter or underwriters will be set forth on the cover of such prospectus supplement. Unless otherwise set forth in the prospectus supplement, the underwriters will be obligated to purchase all the ordinary shares if any are purchased.

Table of Contents

During and after an offering through underwriters, the underwriters may purchase and sell or distribute the ordinary shares in the open market. These transactions may include overallotment and stabilizing transactions and purchases to cover syndicate short positions created in connection with the offering. The underwriters also may impose a penalty bid, under which selling concessions allowed to syndicate members or other broker-dealers for the ordinary shares they sell or distribute for their account may be reclaimed by the syndicate if the syndicate repurchases the ordinary shares in stabilizing or covering transactions. These activities may stabilize, maintain or otherwise affect the market price of the ordinary shares, which may be higher than the price that might otherwise prevail in the open market, and, if commenced, may be discontinued at any time.

Through Agents or to Dealers

We may sell or distribute the ordinary shares directly or through agents we designate from time to time. Unless otherwise indicated in a prospectus supplement, any such agent will be acting on a best efforts basis for the period of its appointment.

If dealers are used in any of the sales or distribution of the ordinary shares covered by this prospectus, we will sell those ordinary shares to dealers as principals. The dealers may then resell the ordinary shares to the public at varying prices the dealers determine at the time of resale.

Direct Sales

We may sell or distribute the ordinary shares 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 thereof.

Delayed Delivery

If so indicated in a prospectus supplement, we may authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase the ordinary shares from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. These contracts will be subject only to those conditions set forth in the prospectus supplement, and the prospectus supplement will set forth the commission payable for solicitation of such contracts.

Derivative Transactions and Hedging

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

Loans of Securities

We may loan or pledge the ordinary shares to a financial institution or other third party that in turn may sell the ordinary shares using this prospectus and an applicable prospectus supplement.

Table of Contents

General

Agents, dealers and direct purchasers that participate in the distribution of the offered ordinary shares may be underwriters as defined in the Securities Act and any discounts or commissions they receive from us and any profit on the resale of the offered ordinary shares by them may be treated as underwriting discounts and commissions under the Securities Act. Agents, dealers and underwriters may be entitled under agreements entered into with us to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, or to contribution with respect to payments which such agents, dealers or underwriters may be required to make in respect thereof. Agents, dealers and underwriters may be customers of, engage in transactions with, or perform services on our behalf.
