Zai Lab (1ZL) Risk Analysis

Zai Lab Limited is a company organized under the laws of the Cayman Islands, and a substantial portion of our assets and operations are located in mainland China. In addition, some of our directors and officers are nationals and residents of countries or regions other than the United States or Hong Kong, and a substantial portion of their assets is located outside of the United States and Hong Kong. As a result, it may be difficult to effect service of process within the United States or Hong Kong upon these persons, or to bring an action against us or these individuals in the United States or Hong Kong in the event of a disagreement, under federal securities laws, or otherwise. Even if a third party successfully obtains a foreign judgment against us or these individuals, the laws of the Cayman Islands and mainland China may render them unable to enforce a judgment against our assets or the assets of our directors and officers. There is uncertainty as to whether the courts of the Cayman Islands or mainland China would recognize or enforce judgments of U.S. courts against us or such persons predicated upon the civil liability provisions of securities laws of the United States or any state. Although there are some protections with respect to enforcement in mainland China of judgments rendered by Hong Kong courts as a result of reciprocal recognition and enforcement of judgment arrangements, mainland China does not have treaties or agreements providing for the reciprocal recognition and enforcement of judgments awarded by courts of the United States, the United Kingdom, most other western countries, or Japan. In addition, according to PRC Civil Procedures Law, mainland China courts will not enforce a foreign judgment against us or our directors and officers if they decide that the judgment violates the basic principles of Chinese laws or national sovereignty, security, or public interest. Hence, the recognition and enforcement in mainland China of judgments of a court in any of these jurisdictions in relation to any matter not subject to a binding arbitration provision may be difficult or even impossible.

The market price of our securities has been volatile, and will likely continue to be volatile and subject to wide fluctuations in response to a variety of factors, including the following: - announcements of competitive developments;- regulatory developments affecting us, our licensors and partners, our customers, or our competitors;- announcements regarding litigation or administrative proceedings involving us or our licensors and partners;- actual or anticipated fluctuations in our period-to-period operating results;- changes in financial estimates by securities research analysts;- additions or departures of our executive officers;- fluctuations of exchange rates between the RMB and the U.S. dollar;- release or expiration of lock-up or other transfer restrictions on our outstanding securities; and - sales or perceived sales of additional securities. In addition, the securities markets have experienced, and may in the future experience, significant price and volume fluctuations that are not related to the operating performance of particular companies. Broad market and industry factors may negatively affect the market price of our securities, regardless of our actual operating performance. For example, in the last few years, tensions between the United States and China, the COVID-19 pandemic, and other geopolitical factors have negatively affected stock market and investor sentiment and resulted in significant volatility, including temporary trading halts. Prolonged global capital markets volatility may affect overall investor sentiment towards our securities, which would also negatively affect the trading prices for our securities.

Holders of our ADSs do not have the same rights as our shareholders and may only exercise the voting rights with respect to the underlying ordinary shares in accordance with the provisions of the deposit agreement. Under our amended and restated articles of association, an annual general meeting and any extraordinary general meeting may be called with not less than fourteen days' notice. When a general meeting is convened, you may not receive sufficient notice of a shareholders' meeting to permit you to withdraw the ordinary shares underlying your ADSs to allow you to vote with respect to any specific matter. If we ask for your instructions, we will give the depositary notice of any such meeting and details concerning the matters to be voted upon at least 30 days in advance of the meeting date, and the depositary will send a notice to you about the upcoming vote and will arrange to deliver our voting materials to you. The depositary and its agents, however, may not be able to send voting instructions to you or carry out your voting instructions in a timely manner. We will make commercially reasonable efforts to cause the depositary to extend voting rights to you in a timely manner, but we cannot assure you that you will receive the voting materials in time to instruct the depositary to vote the ordinary shares underlying your ADSs. Furthermore, the depositary will not be liable for any failure to carry out any instructions to vote, for the manner in which any vote is cast or for the effect of any such vote. As a holder or beneficial owner of ADSs, you may have limited recourse if we or the depositary fail to meet our respective obligations under the deposit agreement or if you wish us or the depositary to participate in legal proceedings. As a result, you may not be able to exercise your right to vote and you may lack recourse if your ADSs are not voted as you request. In addition, in your capacity as an ADS holder, you will not be able to call a shareholders' meeting. Under the deposit agreement, for the ADSs, the depositary will give us a discretionary proxy to vote the ordinary shares underlying your ADS at shareholders' meeting if you do not give instructions to the depositary, unless (i) we have failed to timely provide the depositary with our notice of meeting and related voting materials, (ii) we have instructed the depositary that we do not wish a discretionary proxy to be given, (iii) we have informed the depositary that there is a substantial opposition as to a matter to be voted on at the meeting, or (iv) a matter to be voted on at the meeting would have a material adverse impact on shareholders. The effect of this discretionary proxy is that, if you fail to give voting instructions to the depositary, you cannot prevent the ordinary shares underlying your ADSs from being voted, except under the circumstances described above. This may adversely affect your interests and make it more difficult for ADS holders to influence the management of the Company. Holders of our ordinary shares are not subject to this discretionary proxy.

We may from time to time distribute rights to our shareholders, including rights to acquire our securities. However, we cannot make rights available to our shareholders in the United States unless we register the rights and the securities to which the rights relate under the Securities Act or an exemption from the registration requirements is available. Also, under the deposit agreement, the depositary will not make rights available to our U.S. shareholders unless either both the rights and any related securities are registered under the Securities Act, or the distribution of them to ADS holders is exempted from registration under the Securities Act. We are under no obligation to file a registration statement with respect to any such rights or securities or to endeavor to cause such a registration statement to be declared effective. Moreover, we may not be able to establish an exemption from registration under the Securities Act. If the depositary does not distribute the rights, it may, under the deposit agreement, either sell them, if possible, or allow them to lapse. Accordingly, our U.S. shareholders may be unable to participate in our rights offerings and may experience dilution in their holdings.

If a U.S. investor is treated as owning (directly, indirectly, or constructively) at least 10% of either the total value or total combined voting power of our ADSs or our ordinary shares, such U.S. investor may be treated as a "U.S. shareholder" with respect to each controlled foreign corporation, or CFC, in the Company (if any). Because the Company includes at least one U.S. subsidiary (Zai Lab (US) LLC), certain of our non-U.S. subsidiaries will be treated as CFCs (regardless of whether Zai Lab Limited is treated as a CFC). A U.S. shareholder of a CFC may be required to annually report and include in its U.S. taxable income its pro rata share of "Subpart F income," "global intangible low-taxed income" and investments in U.S. property by CFCs, regardless of whether we make any distributions. An individual that is a U.S. shareholder with respect to a CFC generally would not be allowed certain tax deductions or foreign tax credits that would be allowed to a U.S. shareholder that is a U.S. corporation. We may not assist investors in determining whether any of our non-U.S. subsidiaries are treated as a CFC or whether such investor is treated as a U.S. shareholder with respect to any of such CFCs. Further, we may not furnish to any investors information that may be necessary to comply with the reporting and tax paying obligations discussed above. Failure to comply with these reporting obligations may subject a U.S. investor to significant monetary penalties and may prevent the statute of limitations with respect to their U.S. federal income tax return for the year for which reporting was due from starting. U.S. investors should consult their tax advisors regarding the potential application of these rules to their investment in our securities.

Our directors, executive officers, and other principal shareholders could exert substantial influence over matters such as electing directors and approving material mergers, acquisitions, or other business combination transactions. This may discourage, delay, or prevent a change in control of the Company, which could deprive our shareholders of an opportunity to receive a premium for their shares as part of a sale of the Company and reduce the price of our securities. Such actions may be taken even if they are opposed by certain of our other shareholders. In addition, our directors, executive officers, and other principal shareholders could divert business opportunities away from us to themselves or others.

ADSs are transferable on the books of the depositary. However, the depositary may close its transfer books at any time when it deems expedient in connection with the performance of its duties. In addition, the depositary may refuse to deliver, transfer, or register transfers of ADSs generally when our books or the books of the depositary are closed, or at any time if we or the depositary deems it advisable to do so because of any requirement of law or of any government or governmental body, or under any provision of the deposit agreement, or for any other reason.

Sales of our ordinary shares, ADSs, or other equity or equity-linked securities, or the perception that these sales could occur, could cause the market price of our securities to decline significantly. All of our ordinary shares represented by ADSs were freely transferable by persons other than our affiliates without restriction or additional registration under the U.S. Securities Act. The shares held by our affiliates are also available for sale, subject to volume and other restrictions as applicable under Rule 144 of the U.S. Securities Act, under trading plans adopted pursuant to Rule 10b5-1 or otherwise. Divestiture in the future of our securities by shareholders, the announcement of any plan to divest our securities, or hedging activity by third-party financial institutions in connection with similar derivative or other financing arrangements entered into by shareholders could cause the price of our securities to decline. Furthermore, any major disposal of our securities by any of our directors or executive officers (or the perception that such disposals may occur) may cause the prevailing market price of our securities to fall, which could negatively impact our ability to raise capital in the future.

The depositary for our ADSs is entitled to charge holders fees for various services including for the issuance of ADSs upon deposit of ordinary shares, cancelation of ADSs, distributions of cash dividends or other cash distributions, distributions of ADSs pursuant to share dividends or other free share distributions, distributions of securities other than ADSs, and annual service fees. In the case of ADSs issued by the depositary into The Depository Trust Company, or DTC, the fees will be charged by the DTC participant to the account of the applicable beneficial owner in accordance with the procedures and practices of the DTC participant as in effect at the time. Additionally, dealings in the ordinary shares registered in our Hong Kong register of members will be subject to Hong Kong stamp duty.

Subject to compliance with U.S. securities law and the terms of the deposit agreement, holders of our ordinary shares may deposit such ordinary shares with the depositary in exchange for the issuance of our ADSs. Any holder of ADSs may also withdraw the underlying ordinary shares represented by the ADSs pursuant to the terms of the deposit agreement for trading on the Hong Kong Stock Exchange. If a substantial number of our ordinary shares are deposited with the depositary in exchange for ADSs or vice versa, the liquidity and trading price of our ordinary shares on the Hong Kong Stock Exchange and our ADSs on Nasdaq may be adversely affected.

There is no direct trading or settlement between Nasdaq and the Hong Kong Stock Exchange on which our ADSs and ordinary shares are respectively traded. In addition, the time differences between Hong Kong and New York and unforeseen market circumstances or other factors may delay the deposit of ordinary shares in exchange of ADSs or the withdrawal of ordinary shares underlying the ADSs. Investors will be prevented from settling or effectuating the sale of their securities during such periods of delay. In addition, there is no assurance that any exchange of ADSs into ordinary shares (and vice versa) will be completed in accordance with the timelines investors may anticipate. Furthermore, the depositary for the ADSs is entitled to charge holders fees for various services including for the issuance of ADSs upon deposit of ordinary shares, cancellation of ADSs, distributions of cash dividends or other cash distributions, distributions of ADSs pursuant to share dividends or other free share distributions, distributions of securities other than ADSs, and annual service fees. As a result, shareholders who exchange ADSs into ordinary shares, and vice versa, may not achieve the level of economic return they may anticipate.

In recent years, our company as well as other companies in our industry have experienced significant share price volatility. As a result, we may be at increased risk of securities class action litigation. Historically, securities class action litigation, whether warranted or not, often follows a decline in the market price of a company's securities. If we were to become subject to class action litigation, it could result in substantial costs and a diversion of management's attention and resources, which could harm our business.
