PRESENTATION OF FINANCIAL INFORMATION
Our consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States, or U.S. GAAP. 
For the years presented in our audited consolidated financial statements included elsewhere in this annual report, our reporting currency is U.S dollars. All 
references in this annual report to “$” are to U.S. dollars, and all references to “RMB” are to Renminbi. Tabular amounts are in U.S. dollars in thousands, 
except for share and per share amounts, unless otherwise noted. This annual report contains certain translations of RMB amounts into U.S. dollars. We 
make no representation that the RMB or U.S. dollar amounts referred to in this Annual Report could have been or could be converted into U.S. dollars or 
RMB, as the case may be, at any particular rate or at all.
We have made rounding adjustments to some of the figures included in this annual report. Accordingly, numerical figures shown as totals in some 
tables may not be an arithmetic aggregation of the figures that preceded them. 
INDUSTRY AND MARKET DATA 
This annual report contains estimates, projections and other information concerning our industry, our business and the market for our drug candidates. 
Information that is based on estimates, forecasts, projections, market research or similar methodologies is inherently subject to uncertainties, and actual 
events or circumstances may differ materially from events and circumstances that are assumed in this information. Unless otherwise expressly stated, we 
obtained this industry, business, market and other data from our own internal estimates and research as well as from reports, research surveys, studies and 
similar data prepared by market research firms and other third parties, industry, medical and general publications, government data and similar sources. 
While we believe our internal company research related to such matters is reliable and the market definitions are appropriate, neither such research nor 
these definitions have been verified by any independent source. 
In addition, assumptions and estimates of our and our industry’s future performance are necessarily subject to a high degree of uncertainty and risk 
due to a variety of factors, including those described in the section titled “Risk Factors.” These and other factors could cause our future performance to 
differ materially from our assumptions and estimates. See “Forward-Looking Statements.”

FORWARD-LOOKING STATEMENTS
This annual report on Form 20-F contains forward-looking statements that relate to our current expectations and views of future events. These

“estimate,” “intend,” “plan,” “believe,” “is/are likely to,” “potential,” “continue” or other similar expressions. We have based these forward-looking 
statements largely on our current expectations and projections about future events that we believe may affect our financial condition, results of operations,

Table of Contents
Our investors should read this annual report and the documents that we refer to in this annual report and have filed as exhibits to this annual report 
completely and with the understanding that our actual future results may be materially different from what we expect. Other sections of this annual report 
discuss factors which could adversely impact our business and financial performance. Moreover, we operate in an evolving environment. New risk factors 
emerge from time to time and it is not possible for our management to predict all risk factors, nor can we assess the impact of all factors on our business or 
the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking 
statements. We qualify all of our forward-looking statements by these cautionary statements.
Our investors should not rely upon forward-looking statements as predictions of future events. The forward-looking statements made in this annual 
report relate only to events or information as of the date on which the statements are made in this annual report. Except as required by law, we undertake no 
obligation to update or revise publicly any forward-looking statements, whether as a result of new information, future events or otherwise, after the date on 
which the statements are made or to reflect the occurrence of unanticipated events.

Not applicable.
ITEM 3. KEY INFORMATION
Our Holding Company Structure
I-Mab is a Cayman Islands holding company with its current business operations primarily conducted by its subsidiary based in the United States. 
Investors in our ADSs are purchasing equity interest in a holding company incorporated in the Cayman Islands instead of equity interest in our operating 
subsidiaries. This structure involves unique risks to investors who hold our ADSs.
Prior to April 2024, we conducted business operations in China through I-Mab Biopharma Co., Ltd. (later renamed TJ Biopharma (Shanghai) Co.,
Ltd. and referred to herein as “TJBio Shanghai”) to advance the Greater China portfolio. In February 2024, we entered into definitive agreements with I-
Mab Biopharma (Hangzhou) Co., Ltd. (later renamed TJ Biopharma (Hangzhou) Co., Ltd. and referred to herein as “TJBio Hangzhou”), an unconsolidated 
investee of ours, collectively “TJ Biopharma”, and a group of China-based investors to divest our Greater China assets and business operations. In April 
2024, we closed the divestiture of our Greater China assets and business operations. Since the completion of these transactions, we have conducted our 
business operations primarily through our U.S. subsidiary, with only a small portion of business operations relating to research and development activities 
via collaboration with TJ Biopharma, through our PRC subsidiary, remaining in China. However, any operations that we may conduct through our PRC 
subsidiary are subject to complex and evolving PRC laws and regulations. For example, the PRC government has issued statements and regulatory actions 
relating to areas such as the regulatory approvals on offshore offerings and listings by, and foreign investment in, companies with operations in China, and 
implemented industry-wide regulations, including cybersecurity and data privacy related regulations. The PRC government has significant authority in 
regulating any operations that we may conduct through our PRC subsidiary and may influence any operations that we may conduct through our PRC 
subsidiary. The PRC may exert more oversight and control over offerings conducted overseas by, and foreign investment in, issuers with operations in 
China, which could significantly limit or completely hinder our ability to offer or continue to offer securities to investors. Implementation of industry-wide 
regulations, including data security or anti-monopoly related regulations, in this nature may cause the value of such securities to significantly decline.
Permissions may be Required from the PRC Authorities for the Offering of Our Securities
The PRC government has promulgated certain regulations and rules to exert more oversight and control over offerings that are conducted overseas 
and/or foreign investment in China-based issuers. In connection with the nature and scale of data processed or handled by us in our business operations and 
our historical issuance of securities to foreign investors, under the current PRC laws, regulations and regulatory rules, as of the date of this annual report, 
we and our PRC subsidiary, (i) are not required to go through the filing procedures with regard to the listing and historical issuance of securities by our 
company to foreign investors with the China Securities Regulatory Commission (the “CSRC”) under the Trial Administrative Measures of the Overseas 
Securities Offering and Listing by Domestic Companies, (ii) are not required by the Cyberspace Administration of China (the “CAC”) or any of its local 
counterparts, to go through the cybersecurity review under the Cybersecurity Review Measures, and (iii) have not received or were denied such 
permissions by the CSRC or the CAC. Nevertheless, in the event that we conduct any securities offerings in the future that will be captured by the trial 
administrative measures, we may be required to go through the filing procedures with the CSRC. For more detailed information, see “Item 3. Key 
Information—D. Risk Factors—Risks Related to Our Financial Position and Need for Additional Capital—The approval of and filing with PRC 
government authorities may be required in connection with our offshore offerings under PRC law, and, if required, we cannot predict whether or for how 
long we will be able to obtain such approval or complete such filing.”
The Holding Foreign Companies Accountable Act
Pursuant to the Holding Foreign Companies Accountable Act, which was enacted on December 18, 2020 and further amended by the Consolidated 
Appropriations Act, 2023 signed into law on December 29, 2022 (the “HFCAA”), if the SEC determines that we have filed audit reports issued by a 
registered public accounting firm that has not been subject to inspections by the Public Company Accounting Oversight Board (United States) (“PCAOB”) 
for two consecutive years, the SEC will prohibit our shares or the ADSs from being traded on a national securities exchange or in the over-the-counter 
trading market in the United States. 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

Table of Contents
registered public accounting firms headquartered in mainland China and Hong Kong, including our prior auditor. In May 2022, the SEC conclusively listed 
us as a Commission-Identified Issuer under the HFCAA following the filing of our annual report on Form 20-F for the fiscal year ended December 31, 
2021. On December 15, 2022, the PCAOB issued a report that vacated its December 16, 2021 determination and removed mainland China and Hong Kong 
from the list of jurisdictions where it is unable to inspect or investigate completely registered public accounting firms. While vacating those determinations, 
the PCAOB noted that, should it encounter any impediment to conducting an inspection or investigation of auditors in mainland China or Hong Kong as a 
result of a position taken by any authority there, the PCAOB would act to immediately reconsider the need to issue new determinations consistent with the 
HFCAA and PCAOB’s Rule 6100.
On August 6, 2024, our Audit Committee approved the dismissal of PricewaterhouseCoopers Zhong Tian LLP as our independent registered public 
accounting firm, effective August 7, 2024, and the appointment of PricewaterhouseCoopers LLP as our new independent registered public accounting firm 
for the fiscal year ended December 31, 2024. The office of PricewaterhouseCoopers LLP is located at 400 Campus Drive, Florham Park, NJ 07932 and 
PricewaterhouseCoopers LLP is registered with the PCAOB and subject to PCAOB inspection. Therefore, we believe that, as of the date of this report, 
PricewaterhouseCoopers LLP is not subject to the determinations as to the inability to inspect or investigate registered firms completely announced by the 
PCAOB on December 16, 2021.
PricewaterhouseCoopers Zhong Tian LLP must still be able to produce any audit work papers upon any PCAOB inspection or investigative demand 
and make any relevant audit personnel available to the PCAOB upon inspection or investigative demand. The failure of PricewaterhouseCoopers Zhong 
Tian LLP to meet any of its legal or professional obligations with respect to PCAOB inspection and investigative demands, or the failure of the 
PricewaterhouseCoopers Zhong Tian LLP to comply with all applicable audit standards could result in significant liability for us or result in the delisting of 
our securities pursuant to the HFCAA.
Cash and Asset Flows through Our Organization
I-Mab is a holding company with no operations of its own. We primarily conduct our business through our subsidiary in the United States. As a result, 
although other means are available for us to obtain financing at the holding company level, our ability to pay dividends to our shareholders and holders of 
the ADSs and to service any debt it may incur may depend upon dividends paid by our subsidiaries. If any of our subsidiaries incur debt on its own behalf 
in the future, the instruments governing such debt may restrict its ability to pay dividends to I-Mab. In addition, our PRC subsidiary is permitted to pay 
dividends to I-Mab only out of its retained earnings, if any, as determined in accordance with PRC accounting standards and regulations. Further, our PRC 
subsidiary is required to make appropriations to certain statutory reserve funds or may make appropriations to certain discretionary funds, which are not 
distributable as cash dividends except in the event of a solvent liquidation of the PRC subsidiary. For more details, see “Item 5. Operating and Financial 
Review and Prospects—B. Liquidity and Capital Resources—Holding Company Structure.”
Under PRC laws and regulations, our PRC subsidiary is subject to certain restrictions with respect to paying dividends or otherwise transferring any of 
their net assets to us. Remittance of dividends by a wholly foreign-owned enterprise out of China is also subject to examination by the banks designated by 
the State Administration of Foreign Exchange (“SAFE”). Furthermore, cash transfers from our PRC subsidiary to entities outside of China are subject to 
PRC government control of currency conversion. Shortages in the availability of foreign currency may temporarily delay the ability of our PRC subsidiary 
to remit sufficient foreign currency to pay dividends or other payments to us, or otherwise satisfy their foreign currency denominated obligations. For the 
years ended December 31, 2024, 2023 and 2022, no dividends or distributions were made to I-Mab by our existing PRC subsidiary. As of December 31, 
2024 and 2023, our sole remaining PRC subsidiary held cash and cash equivalents of $0.9 million and $0.5 million, respectively.
Under PRC law, I-Mab may provide funding to our PRC subsidiary only through capital contributions or loans, subject to satisfaction of applicable 
government registration and approval requirements. 
I-Mab has not declared or paid any cash dividends, nor does it have any present plan to pay any cash dividends on our ordinary shares in the 
foreseeable future. We currently intend to retain most, if not all, of our available funds and any future earnings to operate and develop our business. See 
“Item 8. Financial Information—A. Consolidated Statements and Other Financial Information—Dividend Policy.” For PRC and U.S. federal income tax 
considerations of an investment in our ADSs, see “Item 10. Additional Information—E. Taxation.”

Risk Factors
Our business faces significant risks. Before deciding to invest in our securities, you should carefully consider all of the information set forth in this 
annual report and in our other filings with the SEC, including the following risk factors which we face and which are faced by our industry. Our business, 
financial condition or results of operations could be materially adversely affected by any of these risks. This annual report also contains forward-looking 
statements that involve risks and uncertainties. Our results could materially differ from those anticipated in these forward-looking statements, as a result of 
certain factors including the risks described below and elsewhere in this annual report and our other SEC filings. See “Forward-Looking Statements” 
above.
Summary of Risk Factors
An investment in our ADSs or ordinary shares involves significant risks. Below is a summary of material risks we face. These risks are discussed 
more fully in this section.

•
As we rely on third parties to conduct our preclinical studies and clinical trials, if we lose our relationships with these third parties or if they do 
not successfully carry out their contractual duties or meet expected deadlines, we may not be able to obtain regulatory approval for, or 
commercialize our drug candidates and our business could be substantially harmed.
•
We plan to continue to rely on third parties to manufacture our drug candidate supplies, and we intend to rely on third parties for the 
manufacturing process of our drug candidates, if approved. Our business could be harmed if those third parties fail to provide us with sufficient 
quantities of product or fail to do so at acceptable quality levels or prices.
•
If we are unable to obtain and maintain patent and other intellectual property protection for our drug candidates, or if the scope of such 
intellectual property rights obtained is not sufficiently broad, third parties could develop and commercialize products and technologies similar or

Risks Related to Our Financial Position and Need for Additional Capital
We have a limited operating history, which may make it difficult to evaluate our current business and predict our future performance.
We are a clinical-stage biopharmaceutical company with a limited operating history. Our operations to date have focused on organizing and staffing 
our operations, business planning, raising capital, establishing our intellectual property portfolio and conducting preclinical and clinical trials of our drug 
candidates. We have not yet demonstrated an ability to successfully manufacture, obtain marketing approvals for, or commercialize our drug candidates. 
We have no products approved for commercial sale. Consequently, any predictions about our future success or viability may not be as accurate as they 
could be if we had a longer operating history.
We are focused on the development of precision immuno-oncology agents for the treatment of cancer. Our limited operating history, particularly in 
light of the rapidly evolving drug research and development industry in which we operate and the changing regulatory

and market environments we encounter, may make it difficult to evaluate our prospects for future performance. As a result, any assessment of our future 
performance or viability is subject to significant uncertainty. We will encounter risks and difficulties frequently experienced by early-stage companies in 
rapidly evolving fields as we seek to transition to a company capable of supporting commercial activities. If we do not address these risks and difficulties 
successfully, our business will suffer.
We have incurred net losses in the past and we may not be able to maintain profitability in the future.
Investment in the development of biopharmaceutical products is highly speculative as it entails substantial upfront capital expenditures and significant 
risks that a drug candidate may fail to demonstrate efficacy and/or safety to gain regulatory or marketing approvals or become commercially viable. To 
date, we have financed our activities primarily through public and private placements, as well as revenue from licensing and collaboration deals. We have 
incurred significant research and development expenses and other expenses related to our ongoing operations. As a result, we incurred net losses of $22.2 
million, $207.7 million and $371.1 million in 2024, 2023 and 2022, respectively. Substantially all of our net losses have resulted from costs incurred in 
connection with our research and development programs and from administrative costs associated with our operations.
We cannot assure our investors that we will be able to generate net profits in the future. Our ability to achieve and maintain profitability depends in 
large part on our ability to out-license some of our commercialization rights and execute our product commercialization strategies as our business further 
develops. Accordingly, we intend to continue to invest for the foreseeable future in certain activities relating to our development, including the following:
•
conducting clinical trials of our drug candidates;
•
manufacturing clinical trial materials through contract manufacturing organizations;
•
seeking regulatory approvals to advance the development of our drug candidates;
•
commercializing any of our drug candidates for which we have obtained marketing approval;
•
hiring additional clinical, operational, financial, quality control and scientific personnel;
•
establishing a sales, marketing and commercialization team for any future products that have obtained regulatory approval;
•
seeking to identify additional drug candidates;
•
obtaining, maintaining, developing and protecting our intellectual property portfolio;
•
enforcing and defending any intellectual property-related claims; and
•
acquiring or in-licensing other drug candidates, intellectual property and technologies.
Typically, it takes many years to develop a new drug from the time it is discovered to when it becomes available for treating patients. During the 
process, we may encounter unforeseen expenses, difficulties, complications, delays and other unknown factors that may adversely affect our business. The 
size of our future net losses will depend partially on the rate of the future growth of our expenses, our ability to generate revenues and the timing and 
amount of milestone payments and other payments that we receive from or pay to third parties. If any of our drug candidates fails during clinical trials or 
does not gain regulatory approval, or, even if approved, fails to achieve market acceptance, our business may not become profitable. Even if we achieve 
profitability in the future, we may not be able to sustain profitability in subsequent periods thereafter. Our prior losses and expected future losses have had, 
and will continue to have, an adverse effect on our working capital and shareholders’ equity.
We recorded net cash outflow from operating activities in the past. We may need to obtain additional financing to fund our operations. If we are unable 
to obtain such financing, we may be unable to complete the development and commercialization of our drug candidates.
Since our inception, our operations have consumed substantial amounts of cash. We raised over $400 million in pre-IPO financing. In the past, we 
received total net proceeds of approximately $105.3 million, $397.2 million and $105.6 million from our initial public offering, subsequent private 
placement, and warrants issued and subsequently exercised in connection with the private placement, respectively. We used $52.7 million, $72.7 million 
and $49.6 million in net cash in our operations for the years ended December 31, 2024, 2023 and 2022, respectively.

Despite the divestiture of our Greater China assets and business operations, we expect to continue to incur significant expenses in connection with our 
ongoing activities, particularly as we advance the clinical development of our clinical-stage drug candidates, and initiate additional clinical trials of, and 
seek regulatory approval for, these and other potential future drug candidates.
In addition, if we obtain regulatory approvals for any of our drug candidates, we expect to incur significant commercialization expenses relating to 
product manufacturing, marketing, sales and distribution and post-approval commitments to continue monitoring the efficacy and safety data of our future 
products on the market. In particular, the costs that may be required for the manufacture of any drug candidate that has received regulatory approval may be 
substantial. We have incurred and may continue to incur expenses as we create additional infrastructure to support our operations as a public company. 
Accordingly, we will need to obtain substantial additional funding in connection with our continuing operations through public or private equity offerings, 
debt financing, collaborations or licensing arrangements or other sources. If we are unable to raise capital when needed or on acceptable terms, we could be 
forced to delay, limit, reduce or terminate our research and development programs or any future commercialization efforts.
There have been uncertainties and interruptions to the global economy and significant volatility across the financial markets, which had a cooling 
effect on financing and investing activities in general. We believe that our current cash, cash equivalents and short-term investments of $173.4 million will 
be sufficient to meet our present anticipated working capital requirements and capital expenditures into 2027. However, if the volatility in the financial 
markets continues, our financing activities in the future to raise additional capital may be materially and adversely affected, which may in turn have an 
adverse effect on our ability to meet our working capital requirement and our liquidity.
Raising additional capital may cause dilution to the interests to the holders of our ADSs and our shareholders, restrict our operations or require us to 
relinquish rights to our technologies or drug candidates.
We may seek additional funding through a combination of asset sales, equity offerings, debt financings, collaborations, licensing arrangements, 
strategic alliances or partnerships and government grants or subsidies. To the extent that we raise capital through asset sales, we can provide no assurance 
as to the timing of any asset sales or the proceeds that could be realized by us from any such asset sale.
To the extent that we raise additional capital through the sale of equity or convertible debt securities, investor ownership interest will be diluted, and 
the terms may include liquidation or other preferences that adversely affect our investors’ rights as holders of our ADSs. The incurrence of indebtedness or 
the issuance of certain equity securities could give rise to increased fixed payment obligations and also result in certain additional restrictive covenants, 
such as limitations on our ability to incur additional debt or issue additional equity, limitations on our ability to acquire or license intellectual property 
rights and other operating restrictions that could adversely impact our ability to conduct our business. In addition, the issuance of additional equity 
securities, or the possibility of such issuance, may cause the market price of our ADSs to decline.
In the event we enter into collaborations or licensing arrangements in order to raise capital, we may be required to accept unfavorable terms, including 
relinquishing or licensing to a third party our rights to technologies or drug candidates on unfavorable terms, which we would have otherwise sought to 
develop or commercialize on our own or reserve for future potential arrangements when we are more likely to achieve more favorable terms.
The approval of and filing with PRC government authorities may be required in connection with our offshore offerings under PRC law, and, if 
required, we cannot predict whether or for how long we will be able to obtain such approval or complete such filing.
The Regulations on Mergers and Acquisitions of Domestic Enterprises by Foreign Investors adopted by six PRC regulatory agencies in 2006 and 
amended in 2009, require an overseas special purpose vehicle formed for listing purposes through acquisitions of PRC domestic companies and controlled 
by PRC persons or entities to obtain the approval of the CSRC prior to the listing and trading of such special purpose vehicle’s securities on an overseas 
stock exchange. The interpretation and application of the regulations remain unclear, and our offshore offerings may ultimately require approval of the 
CSRC. If the CSRC approval is required, it is uncertain whether we can or how long it will take us to obtain the approval and, even if we obtain such 
CSRC approval, the approval could be rescinded. Any failure to obtain or delay in obtaining the CSRC approval for any of our offshore offerings, or a 
rescission of such approval if obtained by us, may subject us to sanctions imposed by the CSRC or other PRC regulatory authorities, which may include 
fines and penalties on our operations in China, restrictions or limitations on our ability to pay dividends outside of China, and other forms of sanctions that 
may materially and adversely affect our business, financial condition, and results of operations.
On February 17, 2023, the CSRC promulgated the Trial Administrative Measures of the Overseas Securities Offering and Listing by Domestic 
Companies along with five relevant guidelines, which came into effect on March 31, 2023. The trial administrative measures comprehensively improve and 
reform the existing regulatory regime for overseas offering and listing of PRC domestic companies’ securities and regulate both direct and indirect overseas 
offering and listing of PRC domestic companies’ securities by 

 
11
Table of Contents
adopting a filing-based regulatory regime. Pursuant to these trial administrative measures, an overseas offering and listing by a domestic company, whether 
directly or indirectly, must be filed with the CSRC. Specifically, the examination and determination of an indirect overseas offering and listing shall be 
conducted on a substance-over-form basis, and an offering and listing will be considered as an indirect overseas offering and listing by a domestic company 
if the issuer meets the following both conditions: (i) the operating income, gross profit, total assets or net assets of such domestic company in the most 
recent fiscal year was more than 50% of the relevant line items in the issuer’s audited consolidated financial statements for that year; and (ii) the main part 
of operating activities is conducted in the PRC or the main place of business is located in the PRC, or the senior management personnel responsible for 
business operations and management are mostly PRC citizens or are ordinarily resident in the PRC. Following the completion of the divestiture of our 
Greater China assets and business operations in April 2024, we conduct a majority of our business outside of China and only conduct a small portion of our 
research and development activities in China, we generate majority of our net assets from outside the PRC, and the majority of our senior management 
personnel responsible for business operations and management are neither PRC citizens nor habitually reside in the PRC, as of the date of this annual 
report. Given such circumstances, as advised by our PRC legal counsel, JunHe LLP, there is a possibility that we will not be subject to the CSRC filing 
requirements in connection with our proposed offering and listing outside China. However, the CSRC and other authorities may take a view that is contrary 
to the opinion of our PRC legal counsel, and we cannot assure our investors that the above-mentioned assets and business operations in China and the 
citizenship of our senior management personnel will not change in the future, there is no assurance that we may not be required to file the relevant 
documents with the CSRC in connection with our proposed offerings and listings outside mainland China in the future. 
Following the issuance of the trial administrative measures, the CSRC subsequently issued several rules and regulations on overseas offerings and 
listings, providing further guidance on the filing requirements in connection with overseas securities issuance and listing by domestic companies. We 
cannot assure our investors that any new rules or regulations promulgated in the future will not impose additional requirements on us. If it is determined in 
the future that approval or filing from any regulatory authorities or other procedures are required for our offshore offerings, it is uncertain whether we can, 
or how long it will take us to, obtain such approval or complete such filing procedures and any such approval or filing could be rescinded or rejected. Any 
failure to obtain or delay in obtaining such approval or completing such filing procedures for our offshore offerings, or a rescission of any such approval or 
filing if obtained by us, may subject us to sanctions by the regulatory authorities. These regulatory authorities may impose fines and penalties on our 
operations in China, limit our ability to pay dividends outside of China, limit our operating privileges in China, delay or restrict the repatriation of the 
proceeds from our offshore offerings into China or take other actions that could materially and adversely affect our business, financial condition, results of 
operations, and prospects, as well as the trading price of our listed securities. These regulatory authorities also may take actions requiring us, or making it 
advisable for us, to halt our offshore offerings before settlement and delivery of the shares offered. Consequently, if investors engage in market trading or 
other activities in anticipation of and prior to settlement and delivery, they do so at the risk that settlement and delivery may not occur. In addition, if any 
regulatory authorities later promulgate new rules or explanations requiring that we obtain their approvals or accomplish the required filing or other 
regulatory procedures for our prior offshore offerings, we may be unable to obtain a waiver of such approval requirements, if and when procedures are 
established to obtain such a waiver. Any uncertainties or negative publicity regarding such approval requirement could materially and adversely affect our 
business, prospects, financial condition, reputation, and the trading price of our listed securities.
We have granted, and may continue to grant, options and other types of awards under our share incentive plans, which may result in increased share-
based compensation expenses.
We have adopted the Second Amended and Restated 2017 Employee Stock Option Plan (the “2017 Plan”), the Second Amended and Restated 2018 
Employee Stock Option Plan (the “2018 Plan”), the 2019 Share Incentive Plan (the “2019 Plan”), the 2020 Share Incentive Plan (the “2020 Plan”), the 
2021 Share Incentive Plan (the “2021 Plan”), the 2022 Share Incentive Plan (the “2022 Plan”), and the 2024 Omnibus Incentive Plan (the “2024 Plan”), for 
the purpose of granting share-based compensation awards to employees, directors and consultants to incentivize their performance and align their interests 
with ours. We recognize expenses in our consolidated financial statements in accordance with U.S. GAAP. As of March 19, 2025, the awards that had been 
granted to our directors, officers, employees and consultants and remained outstanding included (i) options to purchase an aggregate of 291,042 ordinary 
shares under the 2017 Plan, 341,253 ordinary shares under the 2020 Plan, 266,455 ordinary shares under the 2021 Plan, 577,231 ordinary shares under the 
2022 Plan and 9,285,758 ordinary shares under the 2024 Plan, excluding options that were forfeited, cancelled, or exercised after the grant date; and (ii) 
restricted share units to receive an aggregate of 2,008 ordinary shares under the 2020 Plan, an aggregate of 10,414 ordinary shares under the 2021 Plan, an 
aggregate of 108,252 ordinary shares under the 2022 Plan and an aggregate of 4,519,116 ordinary shares under the 2024 Plan, excluding restricted share 
units that were forfeited, cancelled, or vested after the grant date. See “Item 6. Directors, Senior Management and Employees—B. Compensation—Share 
Incentive Plans.”
We believe the granting of share-based compensation is of significant importance to our ability to attract and retain key personnel and employees, and 
we will continue to grant share-based compensation to employees in the future. As a result, our expenses associated with share-based compensation may 
increase, which may have an adverse effect on our results of operations. We may re-evaluate the vesting schedules, lock-up period, exercise price or other 
key terms applicable to the grants under our currently effective share incentive plans from time to time. If we choose to do so, we may experience 
substantial change in our share-based compensation charges.

Our strategic reprioritization and related reduction in force may not achieve our intended outcome.
In January 2025, we announced a strategic reprioritization of resources (the “Realignment Plan”), pursuant to which we will focus our resources on 
advancing our lead program, givastomig, a CLDN18.2 x 4-1BB bispecific antibody, targeting first-line metastatic gastric cancers, with further potential in 
other solid tumors. In connection with the Realignment Plan, we reduced our workforce by approximately 27%. 
The Realignment Plan may result in unintended consequences and costs, such as the loss of institutional knowledge and expertise, attrition beyond the 
intended number of employees, decreased morale among our remaining employees, and the risk that we may not achieve the anticipated benefits of the 
reduction in force. The Realignment Plan could also make it difficult for us to pursue, or prevent us from pursuing, new opportunities and initiatives due to 
insufficient personnel, or require us to incur additional and unanticipated costs to hire new personnel to pursue such opportunities or initiatives. The 
Realignment Plan could also harm our reputation, making our ability to recruit skilled personnel difficult. Any failure to attract or retain qualified personnel 
could prevent us from successfully developing potential drug candidates or supporting our existing license agreements. If we are unable to realize the 
anticipated benefits from the reduction in force, or if we experience significant adverse consequences from the reduction in force, our business, financial 
condition, and results of operations may be materially adversely affected.
Additionally, the prioritization of our capital resources in accordance with Realignment Plan may not prove successful, and we may forgo the pursuit 
of other indications, whether through future collaborations, licenses, other similar arrangements, or otherwise, that could be more successful. Furthermore, 
we may undertake further similar cost-saving initiatives, which may include additional restructuring or workforce reductions. These types of cost-reduction 
activities can be complex and result in unintended consequences and costs, including decreased employee morale, loss of institutional knowledge and 
expertise and could adversely impact our business and financial condition.
Risks Related to Clinical Development of Our Drug Candidates
Clinical development involves a lengthy and expensive process with an uncertain outcome, and results of earlier studies and trials may not be predictive 
of future trial results.
Clinical testing is expensive and lengthy, and its outcome is inherently uncertain. While our exclusive focus is to develop drug candidates with the 
potential to become novel or highly differentiated drugs globally, we cannot guarantee that we are able to achieve this for any of our drug candidates. 
Failure can occur at any time during the clinical development process. The results of preclinical studies and early clinical trials of our drug candidates may 
not be predictive of the results of later-stage clinical trials. Drug candidates during later stages of clinical trials may fail to show the desired results in safety 
and efficacy despite having progressed through preclinical studies and initial clinical trials and despite the level of scientific rigor in the study, design and 
adequacy of execution. In addition, there can be significant variability in safety and/or efficacy results among different trials of the same drug candidate 
due to numerous factors, including demographics, differences in individual patient conditions, such as genetic differences, and other compounding factors, 
such as other medications or pre-existing medical conditions.
In the case of any trials we conduct, results may differ from earlier trials due to the larger number of clinical trial sites, larger number of patients 
enrolled and additional countries and languages involved in such trials. A number of companies in the biopharmaceutical industry have suffered significant 
setbacks in advanced clinical trials due to a lack of efficacy or adverse safety profiles, notwithstanding promising results in earlier trials. We cannot 
guarantee that our future clinical trial results will be favorable based on currently available clinical and preclinical data.
We depend substantially on the success of our drug candidates, all of which are in preclinical or clinical development, and our ability to identify 
additional drug candidates. If we are unable to successfully identify new drug candidates, complete clinical development, obtain regulatory approval 
and commercialize our drug candidates, or experience significant delays in doing so, our business will be materially harmed.
Our business will depend on the successful development, regulatory approval and commercialization of our drug candidates for the treatment of 
patients with our targeted indications, all of which are still in early clinical development, and other new drug candidates that we may identify and develop. 
As of the date of this annual report, we have open INDs with the FDA for three of our drug candidates, givastomig, uliledlimab, and ragistomig. However, 
we cannot guarantee that we will be able to obtain regulatory approvals to conduct clinical trials for our other existing drug candidates in a timely manner, 
or at all. In addition, none of our drug candidates have been approved for marketing in any jurisdiction. Each of our drug candidates will require additional 
preclinical and/or clinical development, regulatory approvals in multiple jurisdictions, development of manufacturing supply and capacity, substantial 
investment and significant marketing efforts before we generate any revenue from product sales.

 
13
Table of Contents
The success of our drug candidates will depend on several factors, including, successful completion of preclinical and/or clinical trials or studies, 
receipt of regulatory approvals from applicable regulatory authorities for planned clinical trials, successful completion of future clinical trials or drug 
registrations, successful manufacturing and commercialization of our existing drug candidates, obtaining coverage and reimbursement from third-party 
payors, hiring sufficient technical experts to oversee all development and regulatory activities and license renewal and meeting safety requirements.
If we do not achieve one or more of these in a timely manner or at all, we could experience significant delays in our ability to obtain approval for our 
drug candidates, which would materially harm our business and we may not be able to generate sufficient revenues and cash flows to continue our 
operations. As a result, our financial condition, results of operations and prospects will be materially and adversely harmed.
We may not be able to identify, discover or in-license new drug candidates, and may allocate our limited resources to pursue a particular drug 
candidate or indication and fail to capitalize on drug candidates or indications that may later prove to be more profitable, or for which there is a greater 
likelihood of success.
Although a substantial amount of our effort will focus on the continued clinical testing, potential approval, and potential commercialization of our lead 
drug candidate, givastomig, the success of our business depends in part upon our ability to identify, license, discover, develop, or commercialize additional 
drug candidates. Research programs to identify new drug candidates require substantial technical, financial, and human resources. We may focus our 
efforts and resources on potential programs or drug candidates that ultimately prove to be unsuccessful. Our research programs or licensing efforts may fail 
to identify, discover or in-license new drug candidates for clinical development and commercialization for a number of reasons, including, without 
limitation, the following:
•
our research or business development methodology or search criteria and process may be unsuccessful in identifying potential drug candidates;
•
our potential drug candidates may be shown to have harmful side effects or may have other characteristics that may make the products 
unmarketable or unlikely to receive marketing approval; and
•
it may take greater human and financial resources to identify additional therapeutic opportunities for our drug candidates or to develop suitable 
potential drug candidates through internal research programs than we possess, thereby limiting our ability to diversify and expand our drug 
portfolio.
Because we have limited financial and managerial resources, we focus on research programs and drug candidates for specific indications. As a result, 
we may forgo or delay pursuit of opportunities with other drug candidates or for other indications that later may prove to have greater commercial potential 
or a greater likelihood of success. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market 
opportunities.
Accordingly, there can be no assurance that we will ever be able to identify additional therapeutic opportunities for our drug candidates or to develop 
suitable potential drug candidates through internal research programs, which could materially adversely affect our future growth and prospects.
If we encounter delays or difficulties enrolling patients in our clinical trials, our clinical development progress could be delayed or otherwise adversely 
affected.
We may not be able to initiate or continue clinical trials for our drug candidates if we are unable to locate and enroll a sufficient number of eligible 
patients to participate in these trials as required by the FDA, or similar regulatory authorities, or if there are delays in the enrollment of eligible patients as a 
result of the competitive clinical enrollment environment. The inability to enroll a sufficient number of patients who meet the applicable criteria for our 
clinical trials would result in significant delays. As of the date of this annual report, we have initiated clinical trials for givastomig and uliledlimab in the 
United States.
In addition, some of our competitors have ongoing clinical trials for drug candidates that treat the same indications as our drug candidates, and 
patients who would otherwise be eligible for our clinical trials may instead enroll in the clinical trials of our competitors’ drug candidates, which may 
further delay our clinical trial enrollments.
Patient enrollment for our clinical trials may be affected by other factors, including, the following:
•
severity of the disease under investigation;

 
14
Table of Contents
•
total size and nature of the patient population;
•
design and eligibility criteria for the clinical trial in question;
•
perceived risks and benefits of the drug candidate under study;
•
our resources to facilitate timely enrollment in clinical trials;
•
patient referral practices of physicians;
•
availability of competing therapies also undergoing clinical trials;
•
our investigators’ or clinical trial sites’ efforts to screen and recruit eligible patients; and
•
proximity and availability of clinical trial sites for prospective patients.
Even if we are able to enroll a sufficient number of patients in our clinical trials, delays in patient enrollment may result in increased costs or may 
affect the timing or outcome of the planned clinical trials, which could prevent completion of these trials and adversely affect our ability to advance the 
development of our drug candidates.
If clinical trials of our drug candidates fail to demonstrate safety and efficacy to the satisfaction of regulatory authorities or do not otherwise produce 
positive results, we may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development and 
commercialization of our drug candidates.
Before obtaining regulatory approval for the sale of our drug candidates, we must conduct extensive clinical trials to demonstrate the safety and 
efficacy of our drug candidates in humans. We may experience numerous unexpected events during, or as a result of, clinical trials that could delay or 
prevent our ability to receive regulatory approval or commercialize our drug candidates, including:
•
regulators, institutional review boards, or ethics committees may not authorize us or our investigators to commence a clinical trial or conduct a 
clinical trial at a prospective trial site;
•
our inability to reach agreements on acceptable terms with prospective CROs and trial sites, the terms of which can be subject to extensive 
negotiation and may vary significantly among different CROs and trial sites;
•
manufacturing issues, including problems with manufacturing, supply quality, compliance with good manufacturing practice or obtaining 
sufficient quantities of a drug candidate from third parties for use in a clinical trial;
•
our partners identify safety concerns in the clinical candidates that we licensed, which lead to the termination of the collaboration and 
development of the underlying clinical candidates with our partners;
•
clinical trials of our drug candidates may produce negative or inconclusive results, and we may decide to conduct additional clinical trials or 
abandon drug development programs, or regulators may require us to do so;
•
the number of patients required for clinical trials of our drug candidates may be larger than we anticipate, enrollment may be insufficient or 
slower than we anticipate or patients may drop out at a higher rate than we anticipate;
•
our third-party contractors, including clinical investigators, may fail to comply with regulatory requirements or meet their contractual obligations 
to us in a timely manner, or at all;
•
we might have to suspend or terminate clinical trials of our drug candidates for various reasons, including a finding of a lack of clinical response 
or other unexpected characteristics or a finding that participants are being exposed to unacceptable health risks;
•
regulators, institutional review boards or ethics committees may require that we or our investigators suspend or terminate clinical research or not 
rely on the results of clinical research for various reasons, including non-compliance with regulatory requirements;

Table of Contents
•
the cost of clinical trials of our drug candidates may be greater than we anticipate; and
•
the supply or quality of our drug candidates, companion diagnostics or other materials necessary to conduct clinical trials of our drug candidates 
may be insufficient or inadequate.
If we fail to timely and effectively address the above challenges, we may (i) be delayed in obtaining regulatory approval for our drug candidates; (ii) 
obtain approval for indications that are not as broad as intended; (iii) not obtain regulatory approval at all; (iv) have the drug removed from the market after 
obtaining regulatory approval; (v) be subject to additional post-marketing testing requirements; (vi) be subject to restrictions on how the drug is distributed 
or used; or (vii) be unable to obtain reimbursement for use of the drug.
Significant clinical trial delays may also increase our development costs and could shorten any periods during which we have the exclusive right to 
commercialize our drug candidates or allow our competitors to bring drugs to market before we do. This could impair our ability to commercialize our drug 
candidates and may harm our business and results of operations.
Risks Related to Obtaining Regulatory Approval for Our Drug Candidates
All material aspects of the research, development and commercialization of pharmaceutical products are heavily regulated.
Jurisdictions in which we intend to conduct our pharmaceutical-industry activities regulate these activities in great depth and detail. We intend to 
focus our activities in the United States and other major global markets. These jurisdictions strictly regulate the pharmaceutical industry, and in doing so 
they employ broadly similar regulatory strategies, including regulation of product development and approval, manufacturing, and marketing, sales and 
distribution of products. However, there are differences in the regulatory requirements that make for a more complex and costly regulatory compliance 
burden for a company like us that plans to operate in these regions.
The process of obtaining regulatory approvals and compliance with appropriate laws and regulations requires the expenditure of substantial time and 
financial resources. Failure to comply with the applicable requirements at any time during the product development process and approval process, or after 
approval, may subject an applicant to administrative or judicial sanctions. These sanctions could include refusal to approve pending applications, 
withdrawal of an approval, license revocation, clinical hold, voluntary or mandatory product recalls, product seizures; total or partial suspension of 
production or distribution, injunctions, fines, refusals of government contracts, providing restitution, undergoing disgorgement, or other civil or criminal 
penalties. Failure to comply with these regulations could have a material adverse effect on our business.
The regulatory approval processes of the FDA and other comparable regulatory authorities are time-consuming and may evolve over time, and if we 
are ultimately unable to obtain regulatory approval for our drug candidates, our business will be substantially harmed.
The time required to obtain the approval of the FDA and other comparable regulatory authorities is inherently uncertain and depends on numerous 
factors, including the substantial discretion of the regulatory authorities. Generally, such approvals take many years to obtain following the commencement 
of preclinical studies and clinical trials. In addition, approval policies, regulations or the type and amount of clinical data necessary to gain approval may 
change during the course of a drug candidate’s clinical development and may vary among jurisdictions. 
Our drug candidates could fail to receive the regulatory approval of the FDA or a comparable regulatory authority for many reasons, including:
•
disagreement with the design or implementation of our clinical trials;
•
failure to demonstrate that a drug candidate is safe and effective for its proposed indication;
•
failure of our clinical trial results to meet the level of statistical significance required for approval;
•
failure of our clinical trial process to pass good clinical practice inspections;
•
failure to demonstrate that a drug candidate’s clinical and other benefits outweigh its safety risks;
•
disagreement with our interpretation of data from preclinical studies or clinical trials;

Table of Contents
•
insufficient data collected from the clinical trials of our drug candidates to support the submission and filing of a new drug application, biologics 
license application or other submissions or to obtain regulatory approval;
•
failure of our drug candidates to pass current good manufacturing practice, inspections during the regulatory review process or across the 
production cycle of our drug;
•
failure of our clinical sites to pass audits carried out by the FDA or comparable regulatory authorities, resulting in a potential invalidation of our 
research data;
•
findings by the FDA or comparable regulatory authorities of deficiencies related to our manufacturing processes or the facilities of third-party 
manufacturers with whom we contract for clinical and commercial supplies;
•
changes in approval policies or regulations that render our preclinical and clinical data insufficient for approval; and
•
failure of our clinical trial process to keep up with any scientific or technological advancements required by approval policies or regulations.
The FDA or a comparable regulatory authority may require more information, including additional preclinical or clinical data, to support approval, 
which may delay or prevent approval and our commercialization plans. Even if we were to obtain approval, regulatory authorities may approve any of our 
drug candidates for fewer or more limited indications than we request, grant approval contingent on the performance of costly post-marketing clinical trials, 
or approve a drug candidate with an indication that is not desirable for the successful commercialization of that drug candidate. Any of the foregoing 
scenarios could materially harm the commercial prospects of our drug candidates.
The failure to obtain a patent term extension and data exclusivity for any drug candidates we may develop could increase the risk of generic 
competition with our products.
In the United States, the Federal Food, Drug and Cosmetic Act provides the opportunity for patent-term restoration, meaning a patent term extension 
of up to five years to reflect patent term lost during clinical trials and the FDA regulatory review process. A patent term extension cannot extend the 
remaining term of a patent beyond a total of 14 years from the date of drug approval, only one patent may be extended and only those claims covering the 
approved drug, a method for using it, or a method for manufacturing it may be extended. Depending upon the timing, duration and specifics of any FDA 
marketing approval process for any drug candidates we may develop, one or more of our U.S. patents, if issued, may be eligible for limited patent term 
extension. However, we may not be granted an extension because of, for example, failing to exercise due diligence during the testing phase or regulatory 
review process, failing to apply within applicable deadlines, failing to apply prior to expiration of relevant patents, or otherwise failing to satisfy applicable 
requirements. Furthermore, the applicable time period or the scope of patent protection afforded could be less than we request.
In addition, the Biologics Price Competition and Innovation Act of 2009 created an abbreviated pathway for the approval of biosimilar and 
interchangeable biologic products. Under this act, an application for a highly similar or “biosimilar” product may not be submitted to the FDA until four 
years following the date that the original branded product was first approved by the FDA. In addition, an application for a biosimilar product cannot be 
approved by the FDA until 12 years after the original branded product was approved under a biologics license application, (“BLA”). The law is complex 
and is still being interpreted and implemented by the FDA. As a result, its ultimate impact, implementation, and meaning are subject to uncertainty.
In other jurisdictions where we seek patent protection for our drug candidates, patent term compensation and patent linkage system may be available 
to us. However, there is no assurance that we may be granted a patent term extension as we request or our pending or future patent applications may qualify 
for patent linkage. If we are unable to obtain patent term extension or the term of any such extension is less than we request, or our pending or future patent 
applications do not qualify for patent linkage, our competitors may obtain approval of competing products following our patent expiration, and our 
business, financial condition, results of operations, and prospects could be materially harmed.
Our drug candidates may cause undesirable adverse events or have other properties that could delay or prevent their regulatory approval, limit the 
commercial profile of an approved label, or result in significant negative consequences following regulatory approval.
Undesirable adverse events caused by our drug candidates could cause us or regulatory authorities to interrupt, delay or halt clinical trials and may
result in a more restrictive label, a delay or denial of regulatory approval by the FDA or other comparable regulatory authorities, or a significant change in 
our clinical protocol or even our development plan. In particular, as is the case with drugs treating 

 
17
Table of Contents
cancers, it is likely that there may be side effects, such as liver toxicities, cytokine release syndrome, and infusion-related reactions, associated with the use 
of certain of our drug candidates. Results of our trials could reveal a high and unacceptable severity or incidence of certain adverse events. In such an 
event, our trials could be suspended or terminated and the FDA or other comparable regulatory authorities could order us to cease further development of, 
or deny approval of, our drug candidates for any or all targeted indications. Adverse events related to our drug candidates may affect patient recruitment or 
the ability of enrolled subjects to complete the trial, and could result in potential liability claims. Any of these occurrences may significantly harm our 
reputation, business, financial condition and prospects.
Additionally, if we or others identify undesirable side effects caused by those of our existing drug candidates that have received regulatory approval, 
or our other drug candidates after having received regulatory approval, this may lead to potentially significant negative consequences which include, the 
following:
•
we may suspend marketing of the drug candidate;
•
regulatory authorities may withdraw their approvals of or revoke the licenses for the drug candidate;
•
regulatory authorities may require additional warnings on the label;
•
the FDA may require the establishment of a risk evaluation and mitigation strategy or a comparable regulatory authority may require the 
establishment of a similar strategy that may, for instance, restrict distribution of our drugs and impose burdensome implementation requirements 
on us;
•
we may be required to conduct specific post-marketing studies;
•
we could be subjected to litigation proceedings and held liable for harm caused to subjects or patients; and
•
our reputation may suffer.
Any of these events could prevent us from achieving or maintaining market acceptance of any particular drug candidate that is approved and could 
significantly harm our business, results of operations and prospects.
Further, combination therapy, such as using our wholly-owned drug candidates as well as third-party agents, may involve unique adverse events that 
could be exacerbated compared with adverse events from monotherapies. Results of our trials could reveal a high and unacceptable severity or prevalence 
of adverse events. These types of adverse events could be caused by our drug candidates and could cause us or regulatory authorities to interrupt, delay or 
halt clinical trials and may result in a more restrictive indication or the delay or denial of regulatory approval by the FDA or other comparable regulatory 
authority.
Even if we receive regulatory approval for our drug candidates, we will be subject to ongoing regulatory obligations and continued regulatory review, 
which may result in significant additional expenses and we may be subject to penalties if we fail to comply with regulatory requirements or experience 
unanticipated problems with our drug candidates.
If the FDA or a comparable regulatory authority approves any of our drug candidates, the manufacturing processes, labeling, packaging, distribution, 
adverse event reporting, storage, advertising, promotion and recordkeeping for the drug will be subject to extensive and ongoing regulatory requirements 
on pharmacovigilance. These requirements include submissions of safety and other post-marketing information and reports, registration, random quality 
control testing, adherence to any chemistry, manufacturing and controls, variations, continued compliance with current good manufacturing practice, and 
good clinical practices and potential post-approval studies for the purposes of license renewal.
Any regulatory approvals that we receive for our drug candidates may also be subject to limitations on the approved indicated uses for which the drug 
may be marketed or to the conditions of approval, or contain requirements for potentially costly post-marketing studies, including Phase 4 studies for the 
surveillance and monitoring of the safety and efficacy of the drug.
In addition, once a drug is approved by the FDA or a comparable regulatory authority for marketing, it is possible that there could be a subsequent 
discovery of previously unknown problems with the drug, including problems with third-party manufacturers or 

 
18
Table of Contents
manufacturing processes, or failure to comply with regulatory requirements. If any of the foregoing occurs with respect to our drug products, it may result 
in, among other things:
•
restrictions on the marketing or manufacturing of the drug, withdrawal of the drug from the market, or voluntary or mandatory drug recalls;
•
fines, warning letters or holds on our clinical trials;
•
refusal by the FDA or comparable regulatory authorities to approve pending applications or supplements to approved applications filed by us, or 
suspension or revocation of drug license approvals;
•
refusal by the FDA or comparable regulatory authorities to accept any of our other IND approvals, new drug applications or biologics license 
applications;
•
drug seizure or detention, or refusal to permit the import or export of drugs; and
•
injunctions or the imposition of civil, administrative or criminal penalties.
Any government investigation of alleged violations of law could require us to expend significant time and resources and could generate negative 
publicity. Moreover, regulatory policies may change or additional government regulations may be enacted that could prevent, limit or delay regulatory 
approval of our drug candidates. If we are not able to maintain regulatory compliance, we may lose the regulatory approvals that we have already obtained 
and may not achieve or sustain profitability, which in turn could significantly harm our business, financial condition and prospects.
Risks Related to Commercialization of Our Drug Candidates
Our drug candidates may fail to achieve the degree of market acceptance by physicians, patients, third-party payors and others in the medical 
community necessary for commercial success.
Even if our drug candidates receive regulatory approval, they may nonetheless fail to gain sufficient market acceptance by physicians and patients and 
others in the medical community. Physicians and patients may prefer other drugs or drug candidates to ours. If our drug candidates do not achieve an 
adequate level of acceptance, we may not generate significant revenue from sales of our drugs or drug candidates and may not become profitable.
The degree of market acceptance of our drug candidates, if and only when they are approved for commercial sale, will depend on a number of factors, 
including:
•
the clinical indications for which our drug candidates are approved;
•
physicians, hospitals and patients considering our drug candidates as a safe and effective treatment;
•
whether our drug candidates have achieved the perceived advantages of our drug candidates over alternative treatments;
•
the prevalence and severity of any side effects;
•
product labeling or package insert requirements of the FDA or other comparable regulatory authorities;
•
limitations or warnings contained in the labeling approved by the FDA or other comparable regulatory authorities;
•
timing of market introduction of our drug candidates as well as competitive drugs;
•
cost of treatment in relation to alternative treatments;
•
availability of adequate coverage and reimbursement from third-party payors and government authorities in the United States or any other 
jurisdictions;

 
19
Table of Contents
•
willingness of patients to pay any out-of-pocket expenses in the absence of coverage and reimbursement by third-party payors and government 
authorities;
•
relative convenience and ease of administration, including as compared with alternative treatments and competitive therapies; and
•
the effectiveness of our sales and marketing efforts.
If our drug candidates are approved but fail to achieve market acceptance among physicians, patients, hospitals or others in the medical community, 
we will not be able to generate significant revenue or become profitable. Even if our drugs achieve market acceptance, we may not be able to maintain such 
market acceptance over time if new products or technologies are introduced which are more favorably received than our drugs, are more cost effective or 
render our drugs obsolete.
We face intense competition and rapid technological change and the possibility that our competitors may develop therapies that are similar, more 
advanced, or more effective than ours, which may adversely affect our financial condition and our ability to successfully commercialize our drug 
candidates.
The biotechnology and pharmaceutical industries are intensely competitive and subject to rapid and significant technological change. While our 
exclusive focus is to develop drug candidates with potential to become novel or highly differentiated drugs, we continue to face competition with respect to 
our current drug candidates, and will face competition with respect to any drug candidates that we may seek to develop or commercialize in the future. Our 
competitors include major pharmaceutical companies, specialty pharmaceutical companies and biotechnology companies worldwide. We are developing 
our drug candidates for the treatment of cancer in competition with a number of large biopharmaceutical companies that currently market and sell drugs or 
are pursuing the development of drugs also for the treatment of cancer. Some of these competitive drugs and therapies are based on scientific approaches 
that are the same as or similar to our approach, and others are based on entirely different approaches. For details, see “Item 4. Information on the Company
—B. Business Overview—Our Drug Pipeline.” Potential competitors further include academic institutions, government agencies and other public and 
private research organizations that conduct research, seek patent protection and establish collaborative arrangements for research, development, 
manufacturing and commercialization.
Many of our competitors have substantially greater financial, technical, and other resources, such as larger research and development staff and 
experienced marketing and manufacturing organizations. Additional mergers and acquisitions in the biotechnology and pharmaceutical industries may 
result in even more resources being concentrated in our competitors. As a result, these companies may obtain regulatory approval from the FDA or other 
comparable regulatory authorities more rapidly than we are able to and may be more effective in selling and marketing their products as well.
Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large, established 
companies. Competition may increase further as a result of advances in the commercial applicability of technologies and greater availability of capital for 
investment in these industries. Our competitors may succeed in developing, acquiring, or licensing on an exclusive basis, products that are more effective 
or less costly than any drug candidate that we may develop, or achieve earlier patent protection, regulatory approval, product commercialization, and 
market penetration than we do. Additionally, technologies developed by our competitors may render our potential drug candidates uneconomical or 
obsolete, and we may not be successful in marketing our drug candidates against competitors.
We have no experience in launching and marketing drug candidates. We may not be able to effectively build and manage our sales network, or benefit 
from third-party collaborators’ sales network.
We currently have no sales, marketing or commercial product distribution capabilities and have no experience in marketing drugs. We and our third-
party collaborators will have to compete with other biopharmaceutical companies to recruit, hire, train and retain marketing and sales personnel.
If we are unable or decide not to establish internal sales, marketing and commercial distribution capabilities for any or all of the drugs we develop, we 
will likely pursue collaborative arrangements regarding the sales and marketing of our drugs. However, there can be no assurance that we will be able to 
establish or maintain such collaborative arrangements, or, if we are able to do so, that they will have effective sales forces. Any revenue we receive will 
depend on the efforts of such third parties, which may not be successful. We may have little or no control over the marketing and sales efforts of such third 
parties, and our revenue from product sales may be lower than if we had commercialized our drug candidates ourselves. We will also face competition in 
our search for third parties to assist us with the sales and marketing efforts of our drug candidates.

There can be no assurance that we will be able to develop in-house sales and commercial distribution capabilities or establish or maintain relationships 
with third-party collaborators to successfully commercialize any product, and as a result, we may not be able to generate product sales revenue.
Even if we are able to commercialize any approved drug candidates, reimbursement may be limited or unavailable in certain market segments for our 
drug candidates, and we may be subject to unfavorable pricing regulations, which could harm our business.
The regulations that govern regulatory approvals, pricing and reimbursement for new therapeutic products vary widely from country to country. Some 
countries require approval of the sale price of a drug before it can be marketed. In many countries, the pricing review period begins after marketing or 
licensing approval is granted. In some non-U.S. markets, prescription pharmaceutical pricing remains subject to continuing governmental control even after 
initial approval is granted. As a result, we might obtain regulatory approval for a drug in a particular country, but then be subject to price regulations that 
delay our commercial launch of the drug and negatively impact the revenues we are able to generate from the sale of the drug in that country. Adverse 
pricing limitations may hinder our ability to recoup our investment in one or more drug candidates, even if our drug candidates obtain regulatory approval.
Our ability to commercialize any drugs successfully will also depend in part on the extent to which reimbursement for these drugs and related 
treatments will be available from government health administration authorities, private health insurers and other organizations. Government authorities and 
third-party payors, such as private health insurers and health maintenance organizations, decide which medications they will pay for and establish 
reimbursement levels. A primary trend in the global healthcare industry is cost containment. Government authorities and these third-party payors have 
attempted to control costs by limiting coverage and the amount of reimbursement for particular medications. Increasingly, third-party payors are requiring
that companies provide them with predetermined discounts from list prices and are challenging the prices charged for medical products. We cannot be sure 
that reimbursement will be available for any drug that we commercialize and, if reimbursement is available, what the level of reimbursement will be. 
Reimbursement may impact the demand for, or the price of, any drug for which we obtain regulatory approval. Obtaining reimbursement for our drugs may 
be particularly difficult because of the higher prices often associated with drugs administered under the supervision of a physician. If reimbursement is not 
available or is available only to limited levels, we may not be able to successfully commercialize any drug candidate that we successfully develop. Further, 
coverage policies and third-party payor reimbursement rates may change at any time. Even if favorable coverage and reimbursement status is attained for a 
product for which we receive regulatory approval, less favorable coverage policies and reimbursement rates may be implemented in the future.
There may be significant delays in obtaining reimbursement for approved drug candidates, and coverage may be more limited than the purposes for 
which the drug candidates are approved by the FDA or other comparable regulatory authorities. Moreover, eligibility for reimbursement does not imply 
that any drug will be paid for in all cases or at a rate that covers our costs, including research, development, manufacture, sale and distribution. Interim 
payments for new drugs, if applicable, may also not be sufficient to cover our costs and may not be made permanent. Payment rates may vary according to 
the use of the drug and the clinical setting in which it is used, may be based on payments allowed for lower cost drugs that are already reimbursed, and may 
be incorporated into existing payments for other services. Net prices for drugs may be reduced by mandatory discounts or rebates required by government 
healthcare programs or private payors and by any future weakening of laws that presently restrict imports of drugs from countries where they may be sold 
at lower prices than in the United States. Our inability to promptly obtain coverage and profitable payment rates from both government-funded and private 
payors for any future approved drug candidates and any new drugs that we develop could have a material adverse effect on our business, our operating 
results, and our overall financial condition.
Current and future legislation may increase the difficulty and cost for us to obtain marketing approval of and commercialize our drug candidates and 
affect the prices we may obtain.
In the United States and certain other jurisdictions, there have been a number of legislative and regulatory changes and proposed changes regarding 
the healthcare system that could prevent or delay marketing approval of our drug candidates, restrict post-approval activities and affect our ability to sell 
profitably any drug candidates for which we obtain marketing approval. Our current and future arrangements with healthcare professionals, principal 
investigators, consultants, customers and third-party payors may expose us to broadly applicable fraud and abuse and other healthcare laws. Failure to 
comply with such laws could subject us to significant civil, criminal and administrative penalties. For a detailed discussion of these healthcare laws, see 
“Item 4. U.S. Regulation – Healthcare Regulation - Other U.S. Healthcare Laws and Compliance Requirements.”
Further, in the United States and elsewhere there is significant interest in promoting changes in healthcare systems with the stated goals of containing 
healthcare costs, improving quality and/or expanding access. In the United States for example, the Patient Protection and Affordable Care Act, as amended 
by the Health Care and Education Reconciliation Act of 2010, (collectively, the “ACA”) was passed, which intended to broaden access to health insurance, 
reduce or constrain the growth of healthcare spending, enhance remedies against fraud and abuse, add new transparency requirements for the healthcare 
and health insurance industries, impose new taxes and fees on the health industry and impose additional health policy reforms. Further, on August 16, 
2022, the Inflation Reduction Act of 

 
21
Table of Contents
2022 (“IRA”), was signed into law, which among other things, extends enhanced subsidies for individuals purchasing health insurance coverage in ACA 
marketplaces through plan year 2025. The IRA also eliminates the “donut hole” under the Medicare Part D program beginning in 2025 by significantly 
lowering the beneficiary maximum out-of-pocket cost through a newly established manufacturer discount program.
In addition, the IRA, among other things, (i) directs the Secretary of the U.S. Department of Health and Human Services (“HHS”), to negotiate the 
price of certain high-expenditure, single-source drugs that have been on the market for at least seven years and biologics that have been on the market for at 
least 11 years covered under Medicare Part B and Medicare Part D, and subjects drug manufacturers to civil monetary penalties and a potential excise tax
by offering a price that is not equal to or less than the negotiated “maximum fair price” under the law (the “Medicare Drug Negotiation Program”), and (ii) 
imposes rebates under Medicare Part B and Medicare Part D to penalize price increases that outpace inflation. These provisions began to take effect 
progressively in fiscal year 2023. On August 15, 2024, HHS announced the agreed-upon prices of the first 10 drugs that were subject to price negotiations, 
although the Medicare Drug Price Negotiation Program is currently subject to legal challenges. On January 17, 2025, HHS selected 15 additional products 
covered under Part D negotiation in 2025. Each year thereafter more Part B and Part D products will become subject to the Medicare Drug Price 
Negotiation Program.
Legislative and regulatory proposals have been made to expand post-approval requirements and restrict sales and promotional activities for 
pharmaceutical products. We cannot be sure whether additional legislative changes will be enacted, particularly in light of the recent U.S. Presidential and 
Congressional elections, or whether the FDA regulations, guidance or interpretations will be changed, or what the impact of such changes on the marketing 
approvals, if any, of our drug candidates may be. In addition, increased scrutiny by the U.S. Congress of the FDA’s approval process may significantly 
delay or prevent marketing approval, as well as subject us to more stringent product labeling and post-marketing conditions and other requirements.
As we engage in collaborations worldwide, including conducting clinical trials globally, we may be exposed to specific risks of conducting our business 
and operations in international markets.
Markets outside of the United States form an important component of our growth strategy, as we conduct certain of our clinical trials outside of the 
United States. If we fail to obtain applicable licenses or fail to enter into strategic collaboration arrangements with third parties in these markets, or if these 
collaboration arrangements turn out unsuccessful, our revenue-generating growth potential will be adversely affected.
Moreover, international business relationships subject us to additional risks that may materially adversely affect our ability to attain or sustain 
profitable operations, including:
•
efforts to enter into collaboration or licensing arrangements with third parties in connection with our international sales, marketing and 
distribution efforts may increase our expenses or divert our management’s attention from the acquisition or development of drug candidates;
•
changes in a specific country’s or region’s political and cultural climate or economic condition;
•
differing regulatory requirements for drug approvals and marketing internationally;
•
difficulty of effective enforcement of contractual provisions in local jurisdictions;
•
potentially reduced protection for intellectual property rights;
•
potential third-party patent rights;
•
unexpected changes in tariffs, trade barriers and regulatory requirements;
•
economic weakness, including inflation or political instability;
•
compliance with tax, employment, immigration and labor laws for employees traveling abroad;
•
the effects of applicable local tax structures and potentially adverse tax consequences;
•
currency fluctuations, which could result in increased operating expenses and reduced revenue, and other obligations incidental to doing business 
in another country;

 
22
Table of Contents
•
workforce uncertainty and labor unrest;
•
the potential for so-called parallel importing, which is what happens when a local seller, faced with high or higher local prices, opts to import 
goods from an international market with low or lower prices rather than buying them locally;
•
failure of our employees and contracted third parties to comply with Office of Foreign Assets Control rules and regulations and the Foreign 
Corrupt Practices Act of the United States, and other applicable rules and regulations;
•
production shortages resulting from any events affecting raw material supply or manufacturing capabilities abroad; and
•
business interruptions resulting from geo-political actions, including war and terrorism, or natural disasters, including earthquakes, volcanoes, 
typhoons, floods, hurricanes and fires.
These and other risks may materially adversely affect our ability to attain or sustain revenue from international markets.
If safety, efficacy, or other issues arise with any medical product that is used in combination with our drug candidates, we may be unable to market 
such drug candidate or may experience significant regulatory delays or supply shortages, and our business could be materially harmed.
We plan to develop certain of our drug candidates for use as a combination therapy. If the FDA or another comparable regulatory agency revokes its 
approval of another therapeutic we use in combination with our drug candidates, we will not be able to market our drug candidates in combination with 
such revoked therapeutic. If safety or efficacy issues arise with these or other therapeutics that we seek to combine with our drug candidates in the future, 
we may experience significant regulatory delays, and we may be required to redesign or terminate the applicable clinical trials. In addition, if 
manufacturing or other issues result in a supply shortage of any component of our combination drug candidates or if we cannot secure supply of any 
component of our drug candidates at commercially reasonable or acceptable prices, we may not be able to complete clinical development of our drug 
candidates on our current timeline or within our current budget, or at all.
Lack of third-party combination drugs may materially and adversely affect demand for our drugs.
Our drug candidates are under evaluation to be administered in combination with drugs of other pharmaceutical companies as one regimen. In 
addition, we often use such third-party drugs in our development and clinical trials as controls for our studies. As a result, both the results of our clinical 
trials and the sales of our drugs may be affected by the availability of these third-party drugs. If other pharmaceutical companies discontinue these 
combination drugs, regimens that use these combination drugs may no longer be prescribed, and we may not be able to introduce or find an alternative drug 
to be used in combination with our drugs at all or in a timely manner and on a cost-effective basis. As a result, demand for our drugs may be lowered, 
which would in turn materially or adversely affect our business and results of operations.
Risks Related to Our Reliance on Third Parties
As we rely on third parties to conduct our preclinical studies and clinical trials, if we lose our relationships with these third parties or if they do not 
successfully carry out their contractual duties or meet expected deadlines, we may not be able to obtain regulatory approval for or commercialize our 
drug candidates and our business could be substantially harmed.
We have relied on and plan to continue to rely on third-party CROs to monitor and manage data for some of our ongoing preclinical and clinical 
programs. We rely on these parties for the execution of our preclinical and clinical trials, and control only certain aspects of their activities. Nevertheless, 
we are responsible for ensuring that each of our studies is conducted in accordance with the applicable protocol and legal, regulatory and scientific 
standards, and our reliance on the CROs does not relieve us of our regulatory responsibilities.
We also rely on third parties to assist in conducting our preclinical studies in accordance with good laboratory practices. We and our CROs are 
required to comply with good clinical practice, good laboratory practice and other regulatory regulations and guidelines enforced by the FDA and 
comparable foreign regulatory authorities for all of our drug candidates in clinical development. Regulatory authorities enforce these regulatory 
requirements of good clinical practice, good laboratory practice or other regulatory requirements through periodic inspections of trial sponsors, 
investigators and trial sites. If we or any of our CROs fail to comply with applicable good clinical practice, good laboratory practice or other regulatory 
requirements, the data generated in our clinical trials may be deemed unreliable and the FDA or other comparable regulatory authorities may require us to 
perform additional clinical trials before approving our marketing applications. There can be no assurance that upon inspection by a given regulatory 
authority, such regulatory authority will determine that any of our clinical trials complies with requirements of good clinical practice. In addition, our 
clinical trials must be 

 
23
Table of Contents
conducted with drug candidates or products produced under current good manufacturing practice requirements. Failure to comply with these regulations 
may require us to repeat preclinical studies and clinical trials, which would delay the regulatory approval process.
Our CROs have the right to terminate their agreements with us in the event of an unrectified material breach. If any of our relationships with our third-
party CROs is terminated, we may not be able to (i) enter into arrangements with alternative CROs or do so on commercially reasonable terms or (ii) meet 
our desired clinical development timelines. In addition, there is a natural transition period when a new CRO commences work, and the new CRO may not 
provide the same type or level of services as the original provider and data from our clinical trials may be compromised as a result. There is also a need for 
relevant technology to be transferred to the new CRO, which may take time and further delay our development timelines.
Except for remedies available to us under our agreements with our CROs, we cannot control whether or not our CROs devote sufficient time and 
resources to our ongoing clinical, nonclinical and preclinical programs. If our CROs do not successfully carry out their contractual duties or obligations or 
meet expected deadlines or if the quality or accuracy of the clinical data they obtain is compromised due to their failure to adhere to our clinical protocols, 
regulatory requirements or for other reasons, our clinical trials may be extended, delayed or terminated and we may not be able to obtain regulatory 
approval for or successfully commercialize our drug candidates. As a result, our results of operations and the commercial prospects for our drug candidates 
would be harmed and our costs could increase. In turn, our ability to generate revenues could be delayed or compromised.
Because we rely on third parties, our internal capacity to perform these functions is limited. Outsourcing these functions involves certain risks that 
third parties may not perform to our standards, may not produce results in a timely manner or may fail to perform at all. In addition, the use of third-party 
service providers requires us to disclose our proprietary information to these third parties, which could increase the risk that such information will be 
misappropriated. We currently have a small number of employees, which limits the internal resources we could utilize to identify and monitor our third-
party service providers. To the extent we are unable to identify and successfully manage the performance of third-party service providers in the future, our 
business may be adversely affected. Though we carefully manage our relationships with our CROs, there can be no assurance that we will not encounter 
similar challenges or delays in the future or that these delays or challenges will not have a material adverse impact on our business, financial condition and 
prospects.
We plan to continue to rely on third parties to manufacture our drug candidate supplies, and we intend to rely on third parties for the manufacturing 
process of our drug candidates, if approved. Our business could be harmed if those third parties fail to provide us with sufficient quantities of product 
or fail to do so at acceptable quality levels or prices.
We have relied on and plan to continue to rely on third-party vendors to manufacture supplies and process our drug candidates. We have not yet 
manufactured or processed our drug candidates on a commercial scale and may not be able to do so for any of our drug candidates. We have limited 
experience in managing the manufacturing process, and our process may be more difficult or expensive than the approaches currently in use.
Our reliance on third-party manufacturers exposes us to certain risks, including, the following:
•
we may be unable to identify manufacturers on acceptable terms or at all because the number of potential manufacturers is limited and the 
National Medical Products Administration, (“NMPA”), the FDA or other comparable regulatory authorities must approve any manufacturers as 
part of their regulatory oversight of our drug candidates. This approval would require new testing and compliance inspections of current good 
manufacturing practice by the NMPA, the FDA or other comparable regulatory authorities. In addition, a new manufacturer would have to be 
educated in, or develop substantially equivalent processes for, production of our drugs;
•
our contract manufacturers may have little or no experience with manufacturing our drug candidates, and therefore may require a significant 
amount of support from us in order to implement and maintain the infrastructure and processes required to manufacture our drug candidates;
•
our contract manufacturers may have limited capacity or limited manufacturing slots, which may affect the timeline for the production of our 
drugs;
•
our contract manufacturers might be unable to timely manufacture our drug candidates or produce the quantity and quality required to meet our 
clinical and commercial needs, if any;
•
contract manufacturers may not be able to execute our manufacturing procedures and other logistical support requirements appropriately;

 
24
Table of Contents
•
our future contract manufacturers may not perform as agreed, may not devote sufficient resources to our drugs, or may not remain in the contract 
manufacturing business for the time required to supply our clinical trials or to successfully produce, store and distribute our drugs;
•
our contract manufacturers are subject to ongoing periodic unannounced inspections by the NMPA and the FDA to ensure strict compliance with
current good manufacturing practice and other government regulations in the PRC and the United States, respectively, and by other comparable 
regulatory authorities for corresponding regulatory requirements. We do not have control over third-party manufacturers’ compliance with these 
regulations and requirements;
•
we may not own, or may have to share, the intellectual property rights to any improvements made by our third-party manufacturers in the 
manufacturing process for our drugs;
•
our contract manufacturers could breach or terminate their agreements with us;
•
our contract manufacturers may be unable to sustain their business and become bankrupt as a result;
•
raw materials and components used in the manufacturing process, particularly those for which we have no other source or supplier, may not be 
available or may not be suitable or acceptable for use due to material or component defects;
•
products and components from our third-party manufacturers may be subject to tariffs and additional customs and import charges, which may 
cause us to incur delays or additional costs as a result;
•
our contract manufacturers and critical reagent suppliers may be subject to inclement weather, as well as natural or man-made disasters; and
•
our contract manufacturers may have unacceptable or inconsistent product quality success rates and yields.
Each of these risks could delay or prevent the completion of our clinical trials or the approval of any of our drug candidates by the FDA or other 
comparable regulatory authorities, result in higher costs or adversely impact the commercialization of our drug candidates. In addition, we rely on third 
parties to perform certain specification tests on our drug candidates prior to delivery to patients. If these tests are not appropriately done and test data is not 
reliable, patients could be put at risk of serious harm and the FDA or other comparable regulatory authorities could place significant restrictions on our 
company until deficiencies are remedied.
We also rely on third parties, including those located in China, for supply of our drug candidates, and our strategy is to outsource all manufacturing of 
our drug candidates and products to third parties. For any activities conducted in China, we are exposed to the increased possibility of supply disruptions 
and higher costs in the event of changes in the policies of the U.S. or Chinese governments, political unrest or unstable economic conditions including 
sanctions on China or any of our China-based suppliers. Our manufacturing costs could also increase as a result of future appreciation of the local currency 
in China or increased labor costs if the demand for skilled laborers increases and/or the availability of skilled labor declines in China. In addition, certain 
Chinese biotechnology companies may become subject to trade restrictions, sanctions, other regulatory requirements, or proposed legislation by the U.S. 
government, which could restrict or even prohibit our ability to work with such entities, thereby potentially disrupting the supply of material to us. Such 
disruption could have adverse effects on the development of our drug candidates and our business operations.
The manufacture of biopharmaceutical products is complex and requires significant expertise and capital investment, including the development of 
advanced manufacturing techniques and process controls. Currently, our drug raw materials for our manufacturing activities are supplied by multiple 
source suppliers. We have agreements for the supply of drug materials with manufacturers or suppliers that we believe have sufficient capacity to meet our 
demands. In addition, we believe that adequate alternative sources for such supplies exist. However, there is a risk that, if supplies are interrupted, our 
business would be materially harmed.
Manufacturers of biopharmaceutical products often encounter difficulties in production, particularly in scaling up or out, validating the production 
process, and assuring high reliability of the manufacturing process, including the absence of contamination. These problems include logistics and shipping, 
difficulties with production costs and yields, quality control, including stability of the product, product testing, operator error and availability of qualified 
personnel, as well as compliance with strictly enforced regulations in the United States and other applicable jurisdictions. Further, if contaminants are 
discovered in the supply of our drug candidates or in the manufacturing facilities, such manufacturing facilities may need to be closed for an extended 
period of time for us to investigate and remedy the contamination. There can be no assurance that any stability failures or other issues relating to the 
manufacture of our drug candidates will not occur in the future. Additionally, our contract manufacturers may experience manufacturing difficulties due to 
resource constraints or as a result of labor disputes or unstable political environment. If our contract manufacturers were to encounter 

 
25
Table of Contents
any of these difficulties, or otherwise fail to comply with their contractual obligations, our ability to provide our drug candidate to patients in clinical trials 
would be jeopardized. Any delay or interruption in the supply of clinical trial supplies could delay the completion of our clinical trials, increase the costs 
associated with maintaining clinical trial programs and, depending upon the period of delay, require us to begin new clinical trials at additional expense or 
terminate clinical trials completely.
We have entered into collaborations and may form or seek collaborations or strategic alliances or enter into additional licensing arrangements in the 
future, and we may not realize the benefits of such alliances or licensing arrangements.
We may form or seek strategic alliances, create joint ventures or collaborations, or enter into additional licensing arrangements with third parties that 
we believe will complement or augment our development and commercialization efforts with respect to our drug candidates and any future drug candidates 
that we may develop. For example, in June 2024, we entered into a clinical trial collaboration and supply agreement with Bristol-Myers Squibb Company 
(“BMS”) to evaluate our novel bispecific antibody, givastomig, targeting Claudin18.2 x 4-1BB in clinical trials, in combination with BMS’s anti-PD-1 
monoclonal antibody product known as OPDIVO® (nivolumab). Any of these relationships may require us to incur recurring or non-recurring expenses and 
other charges, increase our near and long-term expenditures, issue securities that dilute the value of our ADSs, or disrupt our management and business. In 
addition, we face significant competition in seeking appropriate strategic partners and the negotiation process is time-consuming and complex. Moreover, 
we may not be successful in our efforts to establish a strategic partnership or other alternative arrangements for our drug candidates because they may be 
deemed to be at too early a stage of development for collaborative effort and third parties may not view our drug candidates as having the requisite 
potential to demonstrate safety and efficacy. If and when we collaborate with a third party for the development and commercialization of a drug candidate, 
we can expect to relinquish some or all of the control over the future success of that drug candidate to the third party.
Further, collaborations involving our drug candidates are subject to specific risks, which include the following:
•
collaborators have significant discretion in determining the efforts and resources that they will apply to a collaboration;
•
collaborators may not pursue the development and commercialization of our drug candidates or may elect not to continue or renew the 
development or commercialization programs based on clinical trial results, change in their strategic focus due to the acquisition of competitive 
drugs, availability of funding, or other external factors, such as a business combination that diverts resources or creates competing priorities;
•
collaborators may delay clinical trials, provide insufficient funding for a clinical trial, discontinue a clinical trial, repeat or conduct new clinical 
trials, or require a new formulation of a drug candidate for clinical testing;
•
collaborators could independently develop, or develop with third parties, drugs that compete directly or indirectly with our drug candidates or 
future drugs;
•
collaborators with marketing and distribution rights to one or more of our drug candidates or future drugs may not commit sufficient resources to 
their marketing and distribution;
•
collaborators may not properly maintain or defend our intellectual property rights or may use our intellectual property or proprietary information 
in a way that gives rise to actual or threatened litigation that could jeopardize or invalidate our intellectual property or proprietary information or 
expose us to potential liability;
•
collaborators may not always be cooperative or responsive in providing their services in a clinical trial;
•
disputes may arise between us and a collaborator that cause a delay or termination of the research, development or commercialization of our drug 
candidates, or that result in costly litigation or arbitration that diverts management attention and resources;
•
collaborations may be terminated and, if terminated, may result in a need for additional capital to pursue further development or 
commercialization of the applicable drug candidates; and
•
collaborators may own or co-own intellectual property covering our drug candidates or future drugs that results from our collaborating with 
them, and in such cases, we would not have the exclusive right to commercialize such intellectual property.
As a result, for any ongoing collaborations or any collaboration or license agreements and strategic partnerships we may enter into in the future, we 
may not be able to realize the benefit of such transactions if we are unable to address the risks mentioned above and

successfully integrate these agreements or partnerships with our existing operations and company culture, which could delay our timelines or otherwise 
adversely affect our business. For example, in September 2020, we granted AbbVie Ireland Unlimited Company (“AbbVie”), a global license, excluding 
mainland China, Hong Kong and Macau, to develop and commercialize lemzoparlimab (as well as certain other compounds directed against CD47). On 
August 15, 2022, we and AbbVie Global Enterprises Ltd. (as an assignee of AbbVie) entered into an amendment to the original licensing and collaboration 
agreement. This amended agreement is referred to as the AbbVie Collaboration Agreement. AbbVie discontinued certain clinical trials of lemzoparlimab, 
and such discontinuations were not related to any specific or unexpected safety concerns. This change led to a lowered probability of achieving a key 
milestone that was included in the consideration of revenue recognition in prior years. Accordingly, we recorded a reduction in the revenue of 
approximately $5.8 million in the second half of 2022. On September 21, 2023, we received a notice from AbbVie, terminating the AbbVie Collaboration 
Agreement in its entirety. As a result, we recognized an impairment of goodwill of $23.0 million in 2023. Following the effectiveness of the termination 
and the divestiture of our Greater China assets and business operations, we currently own the ex-Greater China rights to develop and commercialize certain 
CD47 compounds and products, including lemzoparlimab. For a more detailed discussion, please see “Item 5. Operating and Financial Review and 
Prospects.” 
In addition, we may even face disputes, litigations or other proceedings in relation to our collaboration relationship with other parties. For example, 
disputes have arisen between Tracon Pharmaceuticals, Inc. (“Tracon”) and us in relation to the collaboration agreements to co-develop our proprietary 
CD73 antibody, TJD5 and to co-develop up to five bispecific antibodies. These disputes were presented to a binding arbitration proceeding under the Rules 
of Arbitration of the International Chamber of Commerce before an arbitration tribunal. On April 25, 2023, the arbitration award determined that the 
agreement in relation to TJD5 has been terminated for a pre-agreed termination fee of $9.0 million plus interest payable pursuant to the original agreement, 
and, therefore Tracon has no rights to share any future economics with us. In July 2023, the pre-agreed termination fee in relation to TJD5 and an agreed-
upon portion of Tracon’s legal fees and costs to Tracon were paid by I-Mab. The financial impacts of the transaction were allocated to discontinued 
operations for the periods presented. See “Item 8. Financial Information—A. Consolidated Statements and Other Financial Information—Legal 
Proceedings” for details. We cannot assure our investors that similar disputes will not occur again and that no lawsuits will be initiated by other companies 
in the future. Also, these legal proceedings may be expensive, time-consuming and disruptive to our operations and divert our management’s attention. We 
cannot predict the possible outcome of the legal proceedings of such nature in the future and there can also be no assurance that we will prevail in those 
legal proceedings.
Neither can we be certain that, following a strategic transaction or license, we will be able to achieve the revenue or specific net income that justifies 
such transaction. If we are unable to reach agreements with suitable collaborators on a timely basis, on acceptable terms, or at all, we may have to curtail 
the development of a drug candidate, reduce or delay its development program or one or more of our other development programs, delay its potential 
commercialization or reduce the scope of any sales or marketing activities, or increase our expenditures and undertake development or commercialization 
activities at our own expense. If we elect to fund and undertake development or commercialization activities on our own, we may need to obtain additional 
expertise and additional capital, which may not be available to us on acceptable terms or at all. If we fail to enter into collaborations and do not have 
sufficient funds or expertise to undertake the necessary development and commercialization activities, we may not be able to further develop our drug 
candidates or bring them to market and generate product sales revenue, which would harm our business, financial condition, results of operations and 
prospects.
Risks Related to Our Intellectual Property
If we are unable to obtain and maintain patent and other intellectual property protection for our drug candidates, or if the scope of such intellectual 
property rights obtained is not sufficiently broad, third parties could develop and commercialize products and technologies similar or identical to ours 
and compete directly against us, and our ability to successfully commercialize any product or technology may be adversely affected.
Our success depends in large part on our ability to protect our proprietary technology and drug candidates from competition by obtaining, maintaining,
defending and enforcing our intellectual property rights, including patent rights. Following the divestiture of our Greater China assets and business 
operations and as of the date of this annual report, our owned patent portfolio consists of 63 issued patents and 60 patent applications primarily in 
connection with the drug candidates in our Global portfolio, including two Patent Cooperation Treaty patent applications, five U.S. patent applications and 
53 patent applications in other jurisdictions. We seek to protect the drug candidates and technology that we consider commercially important by filing 
patent applications in the United States and other countries or regions, relying on trade secrets or pharmaceutical regulatory protection or employing a 
combination of these methods. This process is expensive and time-consuming, and we or our licensors may not be able to file and prosecute all necessary 
or desirable patent applications in all jurisdictions at a reasonable cost or in a timely manner. It is also possible that we or our licensors will fail to identify 
patentable aspects of our research and development output before it is too late to obtain patent protection.
The patent position of biotechnology and pharmaceutical companies generally is highly uncertain, involves complex legal and factual questions and 
has in recent years been the subject of much litigation. As a result, the issuance, scope, validity, enforceability and commercial value of our patent rights 
are highly uncertain. Our pending and future patent applications may not result in patents being 

 
27
Table of Contents
issued which protect our technology or drug candidates or which effectively prevent others from commercializing competitive technologies and drug 
candidates. The patent examination process may require us or our licensors to narrow the scope of the claims of our or our licensors’ pending and future 
patent applications, which may limit the scope of patent protection that may be obtained. We cannot assure that all of the potentially relevant prior art 
relating to our patents and patent applications has been found. If such prior art exists, it can invalidate a patent or prevent a patent application from being 
issued as a patent.
Even if patents do issue on any of these applications, there can be no assurance that a third party will not challenge their validity, enforceability, or 
scope, which may result in the patent claims being narrowed or invalidated, or that we will obtain sufficient claim scope in those patents to prevent a third 
party from competing successfully with our drug candidates. We may become involved in interference, inter partes review, post grant review, ex parte 
reexamination, derivation, opposition or similar other proceedings challenging our patent rights or the patent rights of others. An adverse determination in 
any such proceeding could reduce the scope of, or invalidate, our patent rights, allow third parties to commercialize our technology or drug candidates and 
compete directly with us, or result in our inability to manufacture or commercialize drug candidates without infringing third-party patent rights. Thus, even 
if our patent applications issue as patents, they may not issue in a form that will provide us with any meaningful protection, prevent competitors from 
competing with us or otherwise provide us with any competitive advantage.
Our competitors may be able to circumvent our patents by developing similar or alternative technologies or drug candidates in a non-infringing 
manner. The issuance of a patent is not conclusive as to its scope, validity or enforceability, and our owned and licensed patents may be challenged in the 
courts or patent offices in the United States and other countries. Such challenges may result in patent claims being narrowed, invalidated or held 
unenforceable, which could limit our ability to stop or prevent us from stopping others from using or commercializing similar or identical technology and 
drug candidates, or limit the duration of the patent protection of our technology and drug candidates. Given the amount of time required for the 
development, testing and regulatory review of new drug candidates, patents protecting such assets might expire before or shortly after such assets are 
commercialized. As a result, our patent portfolio may not provide us with sufficient rights to exclude others from commercializing drug candidates similar 
or identical to ours.
Changes in either the patent laws or interpretation of the patent laws in the United States and other countries may diminish the value of our patents or 
narrow the scope of our patent protection. Under the America Invents Act enacted in 2011, the United States moved to this first-to-file system in early 2013 
from the previous system under which the first to make the claimed invention was entitled to the patent. Assuming the other requirements for patentability 
are met, the first to file a patent application is entitled to the patent. Publications of discoveries in the scientific literature often lag behind the actual 
discoveries, and patent applications in the United States and other jurisdictions are typically not published until 18 months after filing, or in some cases not 
at all. Therefore, we cannot be certain that we were the first to make the inventions claimed in our patents or pending patent applications, or that we were 
the first to file for patent protection of such inventions.
We enjoy only limited geographical protection with respect to certain patents and may not be able to protect our intellectual property rights throughout 
the world.
Filing and prosecuting patent applications and defending patents covering our drug candidates in all countries throughout the world could be 
prohibitively expensive. Competitors may use our and our licensors’ technologies in jurisdictions where we have not obtained patent protection to develop 
their own drug candidates and, further, may export otherwise infringing drug candidates to territories, where we and our licensors have patent protection, 
but enforcement rights are not as strong as that in the United States or Europe. These drug candidates may compete with our drug candidates, and our and 
our licensors’ patents or other intellectual property rights may not be effective or sufficient to prevent them from competing.
The laws of some jurisdictions do not protect intellectual property rights to the same extent as the laws or rules and regulations in the United States 
and Europe, and many companies have encountered significant difficulties in protecting and defending such rights in such jurisdictions. The legal systems 
of certain countries, particularly certain developing countries, do not favor the enforcement of patents, trade secrets and other intellectual property 
protection, which could make it difficult for us to stop the infringement of our patents or marketing of competing drug candidates in violation of our 
proprietary rights generally. Proceedings to enforce our patent rights in other jurisdictions, whether or not successful, could result in substantial costs and 
divert our efforts and attention from other aspects of our business, could put our patents at risk of being invalidated or interpreted narrowly and our patent 
applications at risk of not issuing as patents, and could provoke third parties to assert claims against us. We may not prevail in any lawsuits that we initiate 
and the damages or other remedies awarded, if any, may not be commercially meaningful. Accordingly, our efforts to enforce our intellectual property 
rights around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we develop or license. 
Furthermore, while we intend to protect our intellectual property rights in our expected significant markets, we cannot ensure that we will be able to initiate 
or maintain similar efforts in all jurisdictions in which we may wish to market our drug candidates. Accordingly, our efforts to protect our intellectual 
property rights in such countries may be inadequate, which may have an adverse effect on our ability to successfully commercialize our drug candidates in 
all of our expected significant foreign markets. If we or our licensors encounter difficulties in protecting, or are otherwise precluded from effectively 
protecting, the intellectual property

rights important for our business in such jurisdictions, the value of these rights may be diminished and we may face additional competition from others in 
those jurisdictions.
Some countries also have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties. In addition, some
countries limit the enforceability of patents against government agencies or government contractors. In those countries, the patent owner may have limited 
remedies, which could materially diminish the value of such patents. If we or any of our licensors is forced to grant a license to third parties with respect to 
any patents relevant to our business, our competitive position may be impaired.
Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee payment, and other 
requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these 
requirements.
Periodic maintenance and annuity fees on any issued patent are due to be paid to the United States Patent and Trademark Office and foreign patent 
agencies over the lifetime of a patent. In addition, the United States Patent and Trademark Office and other foreign patent agencies require compliance with 
a number of procedural, documentary, fee payment, and other similar provisions during the patent application process. While an inadvertent failure to make 
payment of such fees or to comply with such provisions can in many cases be cured by payment of a late fee or by other means in accordance with the 
applicable rules, there are situations in which such non-compliance will result in the abandonment or lapse of the patent or patent application, and the 
partial or complete loss of patent rights in the relevant jurisdiction.
Non-compliance events that could result in abandonment or lapse of a patent or patent application include failure to respond to official actions within 
prescribed time limits, and non-payment of fees and failure to properly legalize and submit formal documents within prescribed time limits. If we or our 
licensors fail to maintain the patents and patent applications covering our drug candidates or if we or our licensors otherwise allow our patents or patent 
applications to be abandoned or lapse, our competitors might be able to enter the market, which would hurt our competitive position and could impair our 
ability to successfully commercialize our drug candidates in any indication for which they are approved.
Our owned and in-licensed patents and other intellectual property may be subject to further priority disputes or to inventorship disputes and similar 
proceedings. If we or our licensors are unsuccessful in any of these proceedings, we may be required to obtain licenses from third parties, which may 
not be available on commercially reasonable terms or at all, or to modify or cease the development, manufacture and commercialization of one or more 
of the drug candidates we may develop, which could have a material adverse impact on our business.
We or our licensors may be subject to claims that former employees, collaborators or other third parties have an interest in our owned or in-licensed 
patents or other intellectual property as an inventor or co-inventor. If we or our licensors are unsuccessful in any interference proceedings or other priority 
or validity disputes (including any patent oppositions) to which we or they are subject, we may lose valuable intellectual property rights through the loss of 
one or more patents owned or licensed or our owned or licensed patent claims may be narrowed, invalidated, or held unenforceable. In addition, if we or 
our licensors are unsuccessful in any inventorship disputes to which we or they are subject, we may lose valuable intellectual property rights, such as 
exclusive ownership of, or the exclusive right to use, our owned or in-licensed patents. If we or our licensors are unsuccessful in any interference 
proceeding or other priority or inventorship dispute, we may be required to obtain and maintain licenses from third parties, including parties involved in 
any such interference proceedings or other priority or inventorship disputes. Such licenses may not be available on commercially reasonable terms or at all, 
or may be non-exclusive. If we are unable to obtain and maintain such licenses, we may need to modify or cease the development, manufacture, and 
commercialization of one or more of our drug candidates. The loss of exclusivity or the narrowing of our owned and licensed patent claims could limit our 
ability to stop others from using or commercializing similar or identical drug products. Any of the foregoing could result in a material adverse effect on our 
business, financial condition, results of operations, or prospects. Even if we are successful in an interference proceeding or other similar priority or 
inventorship disputes, it could result in substantial costs and be a distraction to our management and other employees.
Claims that our drug candidates or the sale or use of our future products infringe, misappropriate or otherwise violate the patents or other intellectual 
property rights of third parties could result in costly litigation or could require substantial time and money to resolve, even if litigation is avoided.
We cannot guarantee that our drug candidates or the sale or use of our future products do not and will not in the future infringe, misappropriate or 
otherwise violate third-party patents or other intellectual property rights. Third parties might allege that we are infringing their patent rights or that we have 
misappropriated their trade secrets, or that we are otherwise violating their intellectual property rights, whether with respect to the manner in which we 
have conducted our research, or with respect to the use or manufacture of the compounds we have developed or are developing. Litigation relating to 
patents and other intellectual property rights in the biotechnology and pharmaceutical industries is common, including patent infringement lawsuits. The 
various markets in which we plan 

 
29
Table of Contents
to operate are subject to frequent and extensive litigation regarding patents and other intellectual property rights. Some claimants may have substantially 
greater resources than we have and may be able to sustain the costs of complex intellectual property litigation to a greater degree and for longer periods of 
time than we could. Third parties might resort to litigation against us or other parties we have agreed to indemnify, which litigation could be based on 
either existing intellectual property or intellectual property that arises in the future.
It is also possible that we failed to identify, or may in the future fail to identify, patents or patent applications held by third parties that cover our drug 
candidates. Therefore, we cannot be certain our drug candidates, or their potential uses, will not infringe patents that are currently issued or that are issued 
in the future. In the event that a third party has also filed a patent application covering one of our drug candidates or a similar invention, our patent 
application may be regarded as a competing application and may not be approved in the end. Additionally, pending patent applications that have been 
published can, subject to certain limitations, be later amended in a manner that could cover our products or their use.
If a third party were to assert claims of patent infringement against us, even if we believe such third-party claims are without merit, a court of 
competent jurisdiction could hold that these third-party patents are valid, enforceable and infringed, and the holders of any such patents may be able to 
block our ability to commercialize the applicable product unless we obtained a license under the applicable patents, or until such patents expire or are 
finally determined to be invalid or unenforceable. Similarly, if any third-party patents were held by a court of competent jurisdiction to cover aspects of our 
compositions, formulations, or methods of treatment, prevention, or use, the holders of any such patents may be able to block our ability to develop and 
commercialize the applicable product unless we obtained a license or until such patent expires or is finally determined to be invalid or unenforceable. In 
addition, defending such claims would cause us to incur substantial expenses and could cause us to pay substantial damages, if we are found to be 
infringing a third party’s patent rights. These damages potentially include increased damages and attorneys’ fees if we are found to have infringed such 
rights willfully. In order to avoid or settle potential claims with respect to any patent or other intellectual property rights of third parties, we may choose or 
be required to seek a license from a third party and be required to pay license fees or royalties or both, which could be substantial. These licenses may not 
be available on acceptable terms, or at all. Even if we were able to obtain a license, the rights may be nonexclusive, which could result in our competitors 
gaining access to the same intellectual property. Ultimately, we could be prevented from commercializing a drug candidate, or be forced, by court order or 
otherwise, to modify or cease some or all aspects of our business operations, if, as a result of actual or threatened patent or other intellectual property 
claims, we are unable to enter into licenses on acceptable terms. Further, we could be found liable for significant monetary damages as a result of claims of 
intellectual property infringement.
Defending against claims of patent infringement, misappropriation of trade secrets or other violations of intellectual property rights could be costly 
and time-consuming, regardless of the outcome. Furthermore, because of the substantial amount of discovery required in connection with intellectual 
property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation. Thus, even if 
we were to ultimately prevail, or to settle at an early stage, such litigation could burden us with substantial unanticipated costs.
Evolvement in the U.S. patent law could diminish the value of patents in general, thereby impairing our ability to protect our drug candidates.
Changes in either the patent laws or interpretation of the patent laws in the United States could increase the uncertainties and costs surrounding the 
prosecution of patent applications and the enforcement or defense of issued patents. Under the Leahy-Smith America Invents Act enacted in 2011, the 
United States moved to a first-to-file system in early 2013, from the previous system under which the first to make a claimed invention was entitled to the 
patent. Publications of discoveries in the scientific and academic literature often lag behind the actual discoveries, and patent applications in the United 
States and other jurisdictions are typically not published until 18 months after filing, or in some cases not at all. Therefore, we cannot be certain that we 
were the first to make the inventions claimed in our patents or pending patent applications, or that we were the first to file for patent protection on the 
inventions claimed in our patents or pending patent applications.
Furthermore, the patent positions of pharmaceutical and biotechnology companies are generally uncertain. Recent U.S. Supreme Court rulings have 
narrowed the scope of patent protection available in certain circumstances and weakened the rights of patent owners in certain situations. For example, in 
Amgen Inc. v. Sanofi, 598 U.S. 594, 143 S. Ct. 1243 (2023), the U.S. Supreme Court held that Amgen’s patent claims to a class of antibodies functionally 
defined by their ability to bind a particular antigen were invalid for lack of enablement where the patent specification provided twenty-six exemplary 
antibodies, but the claimed class of antibodies covered a “vast number” of additional antibodies not disclosed in the specification. The U.S. Supreme Court 
stated that if patent claims are directed to an entire class of compositions of matter, then the patent specification must enable a person skilled in the art to 
make and use the entire class of compositions. In view of the Amgen Inc. v. Sanofi decision, claims directed to monoclonal antibodies or binding fragments 
thereof solely defined by functional properties are now less likely to withstand enablement challenges. This decision and other recent rulings have created 
uncertainty with respect to the validity and enforceability of patents, once obtained. As such, we cannot guarantee 

 
30
Table of Contents
that we will be able to obtain patents covering our drug candidates. Depending on future actions by the U.S. Congress, the federal courts and the United 
States Patent and Trademark Office, the laws and regulations governing patents could change in unpredictable ways. In addition, the complexity and 
uncertainty of the laws of foreign jurisdictions (e.g., European patent laws) have also increased in recent years. Any of the foregoing could have a material 
adverse effect on our owned and in-licensed patent portfolio and our ability to protect and enforce our intellectual property in the future.
Issued patents covering one or more of our drug candidates could be found invalid or unenforceable if challenged in court.
Despite measures we take to obtain and maintain patent and other intellectual property rights with respect to our drug candidates, our intellectual 
property rights could be challenged or invalidated. For example, if we were to initiate legal proceedings against a third party to enforce a patent covering 
one of our drug candidates, the defendant could counterclaim that our patent is invalid and/or unenforceable. Grounds for a validity challenge could be an 
alleged failure to meet any of several statutory requirements, for example, lack of novelty, obviousness or non-enablement. Grounds for an unenforceability 
assertion could be an allegation that someone connected with prosecution of the patent withheld relevant information from the United States Patent and 
Trademark Office, or the applicable foreign counterpart, or made a misleading statement, during prosecution. Although we believe that we have conducted 
our patent prosecution in accordance with a duty of candor and in good faith, the outcome following legal assertions of invalidity and unenforceability 
during patent litigation is unpredictable. If a defendant were to prevail on a legal assertion of invalidity and/or unenforceability, we would lose at least part, 
and perhaps all, of the patent protection on a drug candidate. Even if a defendant does not prevail on a legal assertion of invalidity and/or unenforceability, 
our patent claims may be construed in a manner that would limit our ability to enforce such claims against the defendant and others. Even if we establish 
infringement, the court may decide not to grant an injunction against further infringing activity and instead award only monetary damages, which may not 
be an adequate remedy. In addition, if the breadth or strength of protection provided by our patents is threatened, it could dissuade companies from 
collaborating with us to license, develop, or commercialize our current or future drug candidates. Any loss of patent protection could have a material 
adverse impact on one or more of our drug candidates and our business.
Enforcing our intellectual property rights against third parties may also cause such third parties to file other counterclaims against us, which could be 
costly to defend and could require us to pay substantial damages, cease the sale of certain drugs or enter into a license agreement and pay royalties (which 
may not be possible on commercially reasonable terms or at all).
Intellectual property litigation may lead to unfavorable publicity which may harm our reputation and cause the market price of our ADSs to decline, 
and any unfavorable outcome from such litigation could limit our research and development activities and/or our ability to commercialize our drug 
candidates.
During the course of any intellectual property litigation, there could be public announcements of the results of hearings, rulings on motions, and other 
interim proceedings in the litigation. If securities analysts or investors regard these announcements as negative, the perceived value of our drug candidates, 
future drugs, programs or intellectual property could be diminished. Accordingly, the market price of our ADSs may decline. Such announcements could 
also harm our reputation or the market for our drug candidates, which could have a material adverse effect on our business.
In the event of intellectual property litigation, there can be no assurance that we would prevail, even if the case against us is weak or flawed. If third 
parties successfully assert their intellectual property rights against us, prohibitions against using certain technologies, or prohibitions against 
commercializing our drug candidates, could be imposed by a court or by a settlement agreement between us and a plaintiff. In addition, if we are 
unsuccessful in defending against allegations that we have infringed, misappropriated or otherwise violated the patent or other intellectual property rights 
of others, we may be forced to pay substantial damage awards to the plaintiff. Additionally, we may be required to obtain a license from the intellectual 
property owner in order to continue our research and development programs or to commercialize any resulting product. It is possible that the necessary 
license will not be available to us on commercially acceptable terms, or at all. This may not be technically or commercially feasible, may render our 
products less competitive, or may delay or prevent the launch of our products to the market. Any of the foregoing could limit our research and development 
activities, our ability to commercialize one or more drug candidates, or both.
Most of our competitors are larger than we are and have substantially greater resources. They are, therefore, likely to be able to sustain the costs of 
complex intellectual property litigation longer than we could. In addition, the uncertainties associated with litigation could have a material adverse effect on 
our ability to raise the funds necessary to conduct our clinical trials, continue our internal research programs, in-license needed technology, or enter into 
strategic partnerships that would help us bring our drug candidates to market.
In addition, any future intellectual property litigation, interference or other administrative proceedings will result in additional expense and distraction 
of our personnel. An adverse outcome in such litigation or proceedings may expose us or any future strategic partners to loss of our proprietary position, 
expose us to significant liabilities, or require us to seek licenses that may not be available on commercially acceptable terms, if at all, each of which could 
have a material adverse effect on our business.

If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed. We also may be subject to 
claims that our employees, consultants, or advisers have wrongfully used or disclosed alleged trade secrets of their former employers or claims 
asserting ownership of what we regard as our own intellectual property.
In addition to our issued patents and pending patent applications, we rely on trade secret and confidential information, including unpatented know-
how, technology and other proprietary information, to maintain our competitive position and to protect our drug candidates. We seek to protect this trade 
secret and confidential information, in part, by entering into non-disclosure and confidentiality agreements with parties that have access to them, such as 
our employees, corporate collaborators, outside scientific collaborators, sponsored researchers, contract manufacturers, consultants, advisers and other third 
parties. We also enter into confidentiality and invention or patent assignment agreements with our employees and consultants. However, any of these 
parties may breach such agreements and disclose our proprietary information, and we may not be able to obtain adequate remedies for such breaches. For 
example, due to Tracon’s wrong-doing during the confidential arbitration process, we pursued a trade secret misappropriation lawsuit case against a 
competitor and sought remedies, including monetary damages which we were ultimately unsuccessful. Regardless of the outcome, litigations or arbitrations 
can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors. Enforcing a claim that a 
party illegally disclosed or misappropriated a trade secret can be difficult, expensive and time-consuming, and the outcome is unpredictable. If any of our 
trade secrets were to be lawfully obtained or independently developed by a competitor or other third party, we would have no right to prevent them from 
using that technology or information to compete with us and our competitive position would be harmed.
Furthermore, many of our employees, consultants, and advisers, including our senior management, were previously employed at other biotechnology 
or pharmaceutical companies, including our competitors or potential competitors. Some of these employees, consultants, and advisers, including members 
of our senior management, executed proprietary rights, non-disclosure and non-competition agreements in connection with such previous employment. 
Although we try to ensure that our employees do not use the proprietary information or know-how of others in their work for us, we may be subject to 
claims that we or these employees have used or disclosed intellectual property, including trade secrets or other proprietary information, of any such 
individual’s former employer. We are not aware of any threatened or pending claims related to these matters or concerning the agreements with our senior 
management, but in the future litigation may be necessary to defend against such claims. If we fail in defending any such claims, in addition to paying 
monetary damages, we may lose valuable intellectual property rights or personnel. Even if we are successful in defending against such claims, litigation 
could result in substantial costs and be a distraction to management. In addition, while we typically require our employees, consultants and contractors who 
may be involved in the development of intellectual property to execute agreements assigning such intellectual property to us, we may be unsuccessful in 
executing such an agreement with each party who in fact develops intellectual property that we regard as our own, and furthermore, the assignment of 
intellectual property rights may not be self-executing, or the assignment agreements may be breached, each of which may result in claims by or against us 
related to the ownership of such intellectual property. If we fail in prosecuting or defending any such claims, in addition to paying monetary damages, we 
may lose valuable intellectual property rights. Even if we are successful in prosecuting or defending against such claims, litigation could result in 
substantial costs, be a distraction to our management and scientific personnel and have a material adverse effect on our business, financial condition, results 
of operations and prospects.
We may not be successful in obtaining or maintaining necessary rights for our development pipeline through acquisitions and in-licenses.
Because our programs may involve additional drug candidates that may require the use of proprietary rights held by third parties, the growth of our 
business may depend in part on our ability to acquire and maintain licenses or other rights to use these proprietary rights. We may be unable to acquire or 
in-license any compositions, methods of use, or other intellectual property rights from third parties that we identify. The licensing and acquisition of third-
party intellectual property rights is a competitive area, and a number of more established companies are also pursuing strategies to license or acquire third-
party intellectual property rights that we may consider attractive or necessary. These established companies may have a competitive advantage over us due 
to their size, cash resources and greater clinical development and commercialization capabilities. In addition, companies that perceive us to be a competitor 
may be unwilling to assign or license rights to us. We also may be unable to license or acquire third-party intellectual property rights on terms that would 
allow us to make an appropriate return on our investment or at all. If we are unable to successfully obtain rights to required third-party intellectual property 
rights or maintain the existing intellectual property rights we have, we may have to abandon development of relevant programs or drug candidates, which 
could have a material adverse effect on our business, financial condition, results of operations and prospects for growth.
Our business relies partially on our ability to develop and commercialize drug candidates we have licensed from third parties, and we have entered 
into license agreements with third parties providing us with rights to various third-party intellectual property, including rights in patents and patent 
applications. Our licenses may not encumber all intellectual property rights owned or controlled by the affiliates of our licensors and relevant to our drug 
candidates, and we may need to obtain additional licenses from our existing licensors and others to advance our research or allow commercialization of 
drug candidates we may develop. In such case, we may need to obtain 

 
32
Table of Contents
additional licenses which may not be available on an exclusive basis, on commercially reasonable terms or at a reasonable cost, if at all. In that event, we 
may be required to expend significant time and resources to redesign our drug candidates or the methods for manufacturing them or to develop or license 
replacement technology, all of which may not be feasible on a technical or commercial basis. If we are unable to do so, we may be unable to develop or 
commercialize the affected drug candidates, which could harm our business, financial condition, results of operations, and prospects significantly.
Our rights to develop and commercialize our drug candidates are subject, in part, to the terms and conditions of licenses granted to us by others.
We rely on licenses to certain patent rights and other intellectual property from third parties that are important or necessary to the development of our 
drug candidates. These and other licenses may not provide exclusive rights to use such intellectual property in all relevant fields of use and in all territories 
in which we may wish to develop or commercialize our drug products. As a result, we may not be able to prevent competitors from developing and 
commercializing competitive drug products in territories included in all of our licenses.
We may not have the right to control the preparation, filing, prosecution, maintenance, enforcement, and defense of patents and patent applications 
covering the drug candidates that we license from third parties. Moreover, we have not had and do not have primary control over these activities for certain 
of our patents or patent applications and other intellectual property rights that we jointly own with certain of our licensors and sub-licensors. Therefore, we 
cannot be certain that these patents and patent applications will be prepared, filed, prosecuted, maintained, enforced, and defended in a manner consistent 
with the best interests of our business. If our licensors fail to prosecute, maintain, enforce and defend such patents, or lose rights to those patents or patent 
applications, the rights we have licensed may be reduced or eliminated, and our right to develop and commercialize any of our drugs that are subject of 
such licensed rights could be adversely affected.
Pursuant to the terms of the license agreements with some of our licensors, the licensors may have the first right to control enforcement of our 
licensed patents or defense of any claims asserting the invalidity or unenforceability of these patents. Even if we are permitted to pursue the enforcement or 
defense of our licensed patents, we will require the cooperation of our licensors and any applicable patent owners and such cooperation may not be 
provided to us. We cannot be certain that our licensors will allocate sufficient resources or prioritize their or our enforcement of such patents or defense of 
such claims to protect our interests in the licensed patents. Even if we are not a party to these legal actions, an adverse outcome could harm our business 
because it might prevent us from continuing to license intellectual property that we may need to operate our business. If we lose any of our licensed 
intellectual property, our right to develop and commercialize any of our drug candidates that are subject of such licensed rights could be adversely affected.
In addition, our licensors may have relied on third-party consultants or collaborators or on funds from third parties such that our licensors are not the 
sole and exclusive owners of the patents we in-license. This could have a material adverse effect on our competitive position, business, financial conditions, 
results of operations and prospects.
In spite of our best efforts, our licensors might conclude that we have materially breached our license agreements and might therefore terminate the 
license agreements, thereby removing our ability to develop and commercialize drug products covered by these license agreements. If such licenses are 
terminated, we may be required seek alternative in-license arrangements, which may not be available on commercially reasonable terms or at all, or may be 
non-exclusive. If these in-licenses are terminated, or if the underlying patents fail to provide the intended exclusivity, we may need to modify or cease the 
development, manufacture, and commercialization of one or more of our drug candidates and competitors would have the freedom to seek regulatory 
approval of, and to market, products identical to ours. In addition, we may seek to obtain additional licenses from our licensors and, in connection with 
obtaining such licenses, we may agree to amend our existing licenses in a manner that may be more favorable to the licensors, including by agreeing to 
terms that could enable third parties (potentially including our competitors) to receive licenses to a portion of the intellectual property that is subject to our 
existing licenses. Any of these events could have a material adverse effect on our competitive position, business, financial conditions, results of operations 
and prospects.
If we fail to comply with our obligations in the agreements under which we license intellectual property rights from third parties or otherwise 
experience disruptions to our business relationships with our licensors, we could be required to pay monetary damages or could lose license rights that 
are important to our business.
Under each of our license and intellectual property-related agreements, in exchange for licensing or sublicensing us the right to develop and 
commercialize the applicable drug candidates, our licensors will be eligible to receive from us milestone payments, tiered royalties from commercial sales 
of such drug candidates, assuming applicable approvals from government authorities are obtained, or other payments. Our license and intellectual property-
related agreements also require us to comply with other obligations including development and diligence obligations, providing certain information 
regarding our activities with respect to such drug candidates and/or maintaining the confidentiality of information we receive from our licensors.

 
33
Table of Contents
If we fail to comply with our obligations under our current or future license agreements, our counterparties may have the right to terminate these 
agreements and, upon the effective date of such termination, have the right to re-obtain the licensed and sub-licensed technology and intellectual property. 
If any of our licensors terminate any of our licenses, we might not be able to develop, manufacture or market any drug or drug candidate that is covered by 
the licenses provided for under these agreements and other third parties may be able to market drug candidates similar or identical to ours. In such case, we 
may have to negotiate new or reinstated agreements with less favorable terms, and may be required to provide a grant back license to the licensors under 
our own intellectual property with respect to the terminated products. We may also face claims for monetary damages or other penalties under these 
agreements. While we would expect to exercise all rights and remedies available to us, including seeking to cure any breach by us, and otherwise seek to 
preserve our rights under the intellectual property rights licensed and sublicensed to us, we may not be able to do so in a timely manner, at an acceptable 
cost or at all. In particular, some of the milestone payments are payable upon our drug candidates reaching development milestones before we have 
commercialized, or received any revenue from, sales of such drug candidate, and we cannot guarantee that we will have sufficient resources to make such 
milestone payments. Any uncured, material breach under the license agreements could result in our loss of exclusive rights and may lead to a complete 
termination of our rights to the applicable drug candidate. Any of the foregoing could have a material adverse effect on our business, financial conditions, 
results of operations and prospects.
It is possible that we may be unable to obtain any additional licenses at a reasonable cost or on reasonable terms, if at all. Certain license agreements 
may also require us to meet development thresholds to maintain the license, including establishing a set timeline for developing and commercializing 
products. Disputes may arise regarding intellectual property subject to a license agreement, including:
•
the scope of rights granted under the license agreement and other interpretation-related issues;
•
the extent to which our technology and processes infringe, misappropriate or violate intellectual property of the licensor that is not subject to the 
license agreement;
•
the sublicensing of patent and other rights under our collaborative development relationships;
•
our diligence obligations under the license agreement and what activities satisfy those diligence obligations;
•
the inventorship and ownership of inventions and know-how resulting from the joint creation or use of intellectual property by our licensors and 
us and our partners; and
•
the priority of invention of patented technology.
In addition, the agreements under which we license intellectual property or technology from third parties are complex, and certain provisions in such 
agreements may be susceptible to multiple interpretations. The resolution of any contract interpretation disagreement that may arise could narrow what we 
believe to be the scope of our rights to the intellectual property or technology, or increase what we believe to be our financial or other obligations under the 
agreements, either of which could have a material adverse effect on our business, financial condition, results of operations, and prospects. Moreover, if 
disputes over intellectual property that we have licensed prevent or impair our ability to maintain our current licensing arrangements on commercially 
acceptable terms, we may be unable to successfully develop and commercialize the affected drug candidates, which could have a material adverse effect on 
our business, financial condition, results of operations and prospects. In addition, if our licensors breach the license agreements, we may not be able to 
enforce such agreements against our licensors’ parent entity or affiliates.
Intellectual property rights do not necessarily protect us from all potential threats to our competitive advantage.
The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property rights have limitations, and may 
not adequately protect our business, or permit us to maintain our competitive advantage. The following examples are illustrative:
•
others may be able to make compounds that are similar to our drug candidates but which are not covered by the claims of the patents that we own 
or have exclusively licensed;
•
we might not have been the first to make the inventions covered by the issued patents or pending patent applications that we own or may in the 
future exclusively license, which could result in the patents applied for not being issued or being invalidated after issuing;
•
we might not have been the first to file patent applications covering certain of our inventions, which could result in the patents applied for not 
being issued or being invalidated after issuing;

 
34
Table of Contents
•
others may independently develop similar or alternative technologies or duplicate any of our technologies without infringing our intellectual 
property rights;
•
it is possible that our pending patent applications will not lead to issued patents;
•
issued patents that we own or have exclusively licensed may not provide us with any competitive advantages, or may be held invalid or 
unenforceable, as a result of legal challenges by our competitors or other third parties;
•
we may obtain patents for certain compounds many years before we receive regulatory approval for drugs containing such compounds, and 
because patents have a limited life, which may begin to run prior to the commercial sale of the related drugs, the commercial value of our patents 
may be limited;
•
our competitors might conduct research and development activities in countries where we do not have patent rights and then use the information 
learned from such activities to develop competitive drugs for commercialization in our major markets;
•
we may fail to develop additional proprietary technologies that are patentable;
•
we may fail to apply for or obtain adequate intellectual property protection in all the jurisdictions in which we operate;
•
third parties may gain unauthorized access to our intellectual property due to potential lapses in our information systems; and
•
the patents of others may have an adverse effect on our business, for example by preventing us from commercializing one or more of our drug 
candidates for one or more indications.
Any of the aforementioned threats to our competitive advantage could have a material adverse effect on our business and future prospects.
If our trademarks and trade names are not adequately protected, we may not be able to build name recognition in our markets of interest and our 
competitive position may be adversely affected.
We own registered trademarks. We may not be able to obtain trademark protection in territories that we consider of significant importance to us. In 
addition, any of our trademarks or trade names, whether registered or unregistered, may be challenged, opposed, infringed, cancelled, circumvented or 
declared generic, or determined to be infringing on other marks, as applicable. We may not be able to protect our rights to these trademarks and trade 
names, which we will need to build name recognition by potential collaborators or customers in our markets of interest. Over the long term, if we are
unable to establish name recognition based on our trademarks and trade names, we may not be able to compete effectively and our business may be 
adversely affected.
Terms of our future patents may not be sufficient to effectively protect our drug candidates and business.
In many countries where we file applications for patents, the term of an issued patent is generally 20 years from the earliest claimed filing date of a 
non-provisional patent application in the applicable country. Although various extensions may be available, the life of a patent and the protection it affords 
are limited. Even if we obtain patents covering our drug candidates, we may still be open to competition from other companies, as well as generic 
medications once the patent life has expired for a drug.
If we are unable to obtain patent term extensions or if such extensions are less than requested for, our competitors may obtain approval of competing 
products following our patent expirations and our business, financial condition, results of operations and prospects could be materially harmed as a result.
If we do not obtain additional protection under the Drug Price Competition and Patent Term Restoration Act of 1984 (the “Hatch-Waxman 
Amendments”) and similar legislation in other countries extending the terms of our patents, if issued, relating to our drug candidates, our business 
may be materially harmed.
Depending upon the timing, duration and specifics of FDA regulatory approval for our drug candidates, one or more of our U.S. patents, if issued, 
may be eligible for limited patent term restoration under the Hatch-Waxman Amendments. The Hatch-Waxman Amendments permit a patent term 
extension of up to five years as compensation for patent term lost during drug development and the FDA regulatory review process. Patent term extensions, 
however, cannot extend the remaining term of a patent beyond a total of 14 years from the date of drug approval by the FDA, and only one patent can be 
extended for a particular drug.

 
35
Table of Contents
The application for patent term extension is subject to approval by the United States Patent and Trademark Office, in conjunction with the FDA. We 
may not be granted an extension because of, for example, failing to apply within applicable deadlines, failing to apply prior to expiration of patents or 
otherwise failing to satisfy applicable requirements. Moreover, the applicable time period or the scope of patent protection afforded could be less than we 
request. If we are unable to obtain a patent term extension for a given patent or the term of any such extension is less than we request, the period during 
which we will have the right to exclusively market our drug will be shortened and our competitors may obtain earlier approval of competing drugs, and our 
ability to generate revenues could be materially adversely affected.
Risks Related to Our Industry, Business and Operations
We face significant risks related to the transition of our business focus to the U.S. market and our business and prospects may be materially and 
adversely affected.
With the divestiture of our Greater China assets and business operations, our business has been focused on the development and commercialization of 
drug candidates with ex-Greater China rights. Following the completion of the divestiture, we ceased to own the Greater China portfolio and the number of 
drug candidates in our pipeline was significantly reduced. Moreover, we have recently experienced significant changes in our management. See “—Our 
future success depends on our ability to attract, retain and motivate senior management and qualified scientific employees.” 
As we are going through the transition period, there is no guarantee that we may successfully advance our existing drug candidates in our pipeline 
towards clinical development or successfully executing our business strategies. We may also in the future adjust our business focus or seek other business 
opportunities. Any such changes may have a material adverse impact on our business operations, financial position and our reputation.
Our future success depends on our ability to attract, retain and motivate senior management and qualified scientific employees.
We are highly dependent on the expertise of the members of our research and development team, as well as the principal members of our
management. We have entered into employment agreements with certain of our executive officers, but each of them may terminate their employment with 
us at any time with prior written notice. In addition, we currently do not have “key-man” insurance for any of our executive officers or other key personnel.
Recruiting, retaining and motivating qualified management, scientific, clinical, manufacturing and sales and marketing personnel will also be critical 
to our success. We have recently experienced significant changes in our management and board of directors, including the departure of Raj Kannan as 
Chief Executive Officer and Dr. Pamela Klein as interim chairperson of the board of directors and the appointments of Xi-Yong (Sean) Fu as our interim 
Chief Executive Officer in July 2024 and later permanent Chief Executive Officer in November 2024, Dr. Phillip Dennis as our Chief Medical Officer in 
June 2024 and Joseph Skelton as our Chief Financial Officer in February 2024. The loss of the services of our executive officers or other key employees 
could impede the achievement of our research, development and commercialization objectives and seriously harm our ability to successfully implement our 
business strategy. Further, replacing executive officers and key employees may be difficult and may take an extended period of time because of the limited 
number of individuals in our industry with the breadth of skills and experience required to successfully develop, gain regulatory approval of and 
commercialize drugs. Competition to hire from this limited pool is intense, and we may be unable to hire, train, retain or motivate these key personnel on 
acceptable terms given the competition among numerous biopharmaceutical companies for similar personnel. We also experience competition for the 
hiring of scientific and clinical personnel from universities and research institutions. In addition, our management may need to devote additional time to 
compliance initiatives stemming from our status as a public company, potentially necessitating the recruitment of more management personnel. These 
changes in our management may be disruptive to our business and, during the transition period, there may be uncertainty among investors, employees and 
others concerning our future direction and performance. Any such disruption or uncertainty could have a material adverse effect on our business, financial 
condition, results of operations and our reputation.
We will need to increase the size and capabilities of our organization, and we may experience difficulties in managing our development.
To manage our future development, we may continue to implement and improve our managerial, operational and financial systems, expand our 
facilities and continue to recruit and train additional qualified personnel. Due to our limited financial resources, we may not be able to effectively manage 
our operations or recruit and train additional qualified personnel. The expansion of our operations may 

 
36
Table of Contents
lead to significant costs and may divert our management and business development resources. Any inability to manage growth could delay the execution of 
our business plans or disrupt our operations, and have a material adverse effect on our business.
The data and information that we gather in our research and development process could be inaccurate or incomplete, which could harm our business, 
reputation, financial condition and results of operations.
We collect, aggregate, process, and analyze data and information from our preclinical studies, manufacturing technology development programs and 
clinical programs. We also engage in substantial information gathering following the identification of a promising drug candidate. Because data in the 
healthcare industry is fragmented in origin, inconsistent in format, and often incomplete, the overall quality of data collected or accessed in the healthcare 
industry is often subject to challenge, the degree or amount of data which is knowingly or unknowingly absent or omitted can be material, and we often 
discover data issues and errors when monitoring and auditing the quality of our data. If we make mistakes in the capture, input, or analysis of these data, 
our ability to advance the development of our drug candidates may be materially harmed and our business, prospects and reputation may suffer.
We also engage in the procurement of regulatory approvals necessary for the development and commercialization of our products under development, 
for which we manage and submit data to governmental entities. These processes and submissions are governed by complex data processing and validation 
policies and regulations. Notwithstanding such policies and regulations, interim, top-line or preliminary data from our clinical trials that we announce or 
publish from time to time may change as more patient data become available and are subject to audit and verification procedures that could result in 
material changes in the final data, in which case we may be exposed to liability to a customer, court or government agency that concludes that our storage, 
handling, submission, delivery, or display of health information or other data was wrongful or erroneous.
Although we maintain insurance coverage for clinical trials, this coverage may prove to be inadequate or could cease to be available to us on 
acceptable terms, if at all. Even unsuccessful claims could result in substantial costs and diversion of management time, attention, and resources. A claim 
brought against us that is uninsured or under-insured could harm our business, financial condition and results of operations.
In addition, we rely on CROs, our partners and other third parties to monitor and manage data for some of our ongoing preclinical and clinical 
programs and control only certain aspects of their activities. If any of our CROs, our partners or other third parties do not perform to our standards in terms 
of data accuracy or completeness, data from those preclinical and clinical trials may be compromised as a result, and our reliance on these parties does not 
relieve us of our regulatory responsibilities. For a detailed discussion, see “—Risks Related to Our Reliance on Third Parties—As we rely on third parties 
to conduct our preclinical studies and clinical trials, if we lose our relationships with these third parties or if they do not successfully carry out their 
contractual duties or meet expected deadlines, we may not be able to obtain regulatory approval for or commercialize our drug candidates and our business 
could be substantially harmed.”
We may be subject to liability lawsuits arising from our clinical trials.
We currently carry liability insurance covering our clinical trials. Although we maintain such insurance, any claim that may be brought against us 
could result in a court judgment or settlement in an amount that is not covered, in whole or in part, by our insurance or which is in excess of the limits of 
our insurance coverage. Our insurance policies also contain various exclusions, and we may be subject to particular liability claims for which we have no 
coverage. We will have to pay any amount awarded by a court or negotiated in a settlement that exceed our coverage limitations or that are not covered by 
our insurance, and we may not have, or be able to obtain, sufficient capital to pay such amounts. In addition, if we cannot successfully defend ourselves 
against such claims, we may incur substantial liabilities and be required to suspend or delay our ongoing clinical trials. Even a successful defense would 
require significant financial and management resources.
Regardless of the merits or eventual outcome, liability claims may result in significant negative consequences to our business and prospects, 
including:
•
decreased demand for our drug candidates or any resulting products;
•
injury to our reputation;
•
withdrawal of other clinical trial participants;
•
costs to defend the related litigation;
•
a diversion of our management’s time and resources;

 
37
Table of Contents
•
substantial monetary awards to trial participants or patients;
•
inability to commercialize our drug candidates; and
•
a decline in the market price of our ADSs.
We have limited insurance coverage, and any claims beyond our insurance coverage may result in our incurring substantial costs and a diversion of 
resources.
We maintain insurance policies that are required under certain laws and regulations as well as insurance based on our assessment of our operational 
needs and industry practice. We also maintain liability insurance covering our clinical trials. In line with industry practice, we have elected not to maintain 
certain types of insurances, such as business interruption insurance or key-man insurance. Our insurance coverage may be insufficient to cover any claim 
for product liability, damage to our fixed assets or employee injuries. Any liability or damage to, or caused by, our facilities or our personnel beyond our 
insurance coverage may result in our incurring substantial costs and a diversion of resources.
Disruptions in the financial markets and economic conditions could affect our ability to raise capital.
Global economies could suffer dramatic downturns as a result of a deterioration in the credit markets and related financial crisis as well as a variety of 
other factors including, extreme volatility in security prices, severely diminished liquidity and credit availability, ratings downgrades of certain investments 
and declining valuations of others. In the past, governments have taken unprecedented actions in an attempt to address and rectify these extreme market and 
economic conditions by providing liquidity and stability to the financial markets. If these actions are not successful, the return of adverse economic 
conditions may cause a significant impact on our ability to raise capital, if needed, on a timely basis and on acceptable terms, or at all.
In addition, there is considerable uncertainty over the long-term effects of the expansionary monetary and fiscal policies adopted by the central banks 
and financial authorities of some of the world’s leading economies, including the United States and China. There have been concerns over unrest and 
terrorist threats in the Middle East, Europe and Africa and over the conflicts in Eastern Europe and the Middle East. There have also been concerns on the 
relationship among China and other Asian countries, which may result in or intensify potential conflicts in relation to territorial disputes or the trade related 
disputes between the United States and China. It is unclear whether these challenges and uncertainties will be contained or resolved, and what effects they 
may have on the global political and economic conditions in the long term.
Our employees, independent contractors, consultants, commercial partners and vendors may engage in misconduct or other improper activities, 
including non-compliance with regulatory standards and requirements.
We are exposed to the risk of fraud, misconduct or other illegal activities by our employees, independent contractors, consultants, commercial partners 
and vendors. Misconduct by these parties could include intentional, reckless and negligent conduct that fails to:
•
comply with the laws of the FDA and other comparable regulatory authorities;
•
provide true, complete and accurate information to the FDA and other comparable regulatory authorities;
•
comply with manufacturing standards we have established;
•
comply with healthcare fraud and abuse laws in the United States and similar fraudulent misconduct laws in other applicable jurisdictions; or
•
report financial information or data accurately or to disclose unauthorized activities to us.
If we obtain approval of any of our drug candidates and begin commercializing those drugs in the United States or other applicable jurisdictions, our 
potential exposure under the laws of such jurisdictions will increase significantly and our costs associated with compliance with such laws are also likely to 
increase. These laws may impact, among other things, our current activities with principal investigators and research patients, as well as future sales, 
marketing and education programs. In particular, the promotion, sales and marketing of healthcare items and services, as well as certain business 
arrangements in the healthcare industry, are subject to extensive laws designed to prevent fraud, kickbacks, self-dealing and other abusive practices. These 
laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, structuring and commission(s), certain 
customer incentive programs and

Table of Contents
other business arrangements generally. Activities subject to these laws also involve the improper use of information obtained in the course of patient 
recruitment for clinical trials, which could result in regulatory sanctions and cause serious harm to our reputation.
It is not always possible to identify and deter misconduct by employees and other parties, and the precautions we take to detect and prevent this 
activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or 
lawsuits stemming from a failure to comply with these laws or regulations. If any such actions are instituted against us, and we are not successful in 
defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of significant fines or 
other sanctions.
If we engage in future acquisitions or strategic partnerships, this may increase our capital requirements, dilute the value of our investors’ investments 
in our ADSs, cause us to incur debt or assume contingent liabilities, and subject us to other risks.
We may evaluate various acquisitions and strategic partnerships, including licensing or acquiring complementary products, intellectual property 
rights, technologies or businesses. Any potential acquisition or strategic partnership may entail numerous risks, including:
•
increased operating expenses and cash requirements;
•
the assumption of additional indebtedness or contingent liabilities;
•
the issuance of our equity securities;
•
assimilation of operations, intellectual property and products of an acquired company, including difficulties associated with integrating new 
personnel;
•
the diversion of our management’s attention from our existing product programs and initiatives in pursuing such a strategic merger or 
acquisition;
•
retention of key employees, the loss of key personnel, and uncertainties in our ability to maintain key business relationships;
•
risks and uncertainties associated with the assimilation of operations, corporate culture and personnel of the acquired business;
•
risks and uncertainties associated with the other party to such a transaction, including the prospects of that party and its existing drugs or drug 
candidates and regulatory approvals;
•
our inability to generate revenue from acquired technology and/or products sufficient to meet our objectives in undertaking the acquisition or 
even to offset the associated acquisition and maintenance costs; and
•
changes in accounting principles relating to recognition and measurement of our investments that may have a significant impact on our financial 
results.
In addition, if we undertake acquisitions, we may issue dilutive securities, assume or incur debt obligations, incur large one-time expenses and acquire 
intangible assets that could result in significant future amortization expense. Moreover, we may not be able to locate suitable acquisition opportunities and 
this inability could impair our ability to develop or obtain access to technology or products that may be important to the development of our business.
If we fail to comply with applicable anti-bribery laws, our reputation may be harmed and we could be subject to penalties and significant expenses that 
have a material adverse effect on our business, financial condition and results of operations.
We are subject to the Foreign Corrupt Practices Act, the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the U.S. Travel Act, the USA 
PATRIOT Act, and other state and national anti-bribery and anti-money laundering laws in the countries in which we conduct activities. Anti-corruption 
laws are interpreted broadly and prohibit companies and their employees, agents, contractors, and other collaborators from authorizing, promising, offering, 
or providing, directly or indirectly, improper payments or anything else of value to recipients in the public or private sector. We may engage third parties to 
sell our products outside the United States, to conduct clinical trials, and/or to obtain necessary permits, licenses, patent registrations, and other regulatory 
approvals. We have direct or indirect interactions with officials and employees of government agencies or government-affiliated hospitals, universities, and 
other organizations. We can be held liable for the corrupt or other illegal activities of our employees, agents, contractors, and other collaborators, even if 
we do not explicitly authorize or have actual knowledge of such activities. Although we have policies and 

 
39
Table of Contents
procedures designed to ensure that we, our employees and our agents comply with applicable anti-bribery laws, there is no assurance that such policies or 
procedures will prevent our agents, employees and intermediaries from engaging in bribery activities. Failure to comply with anti-bribery laws could 
disrupt our business and lead to severe criminal and civil penalties, including imprisonment, criminal and civil fines, loss of our export licenses, suspension 
of our ability to do business with the government, denial of government reimbursement for our products and/or exclusion from participation in government 
healthcare programs. Other remedial measures could include further changes or enhancements to our procedures, policies, and controls and potential 
personnel changes and/or disciplinary actions, any of which could have a material adverse effect on our business, financial condition, results of operations 
and liquidity. We could also be adversely affected by any allegation that we violated such laws.
We are subject to governmental export and import controls that could impair our ability to compete in international markets due to licensing 
requirements and subject us to liability if we are not in compliance with applicable laws. Compliance with these legal requirements could limit our 
ability to compete in foreign markets and subject us to liability if we violate them.
We are subject to export control and import laws and regulations, including the U.S. Export Administration Regulations, U.S. Customs regulations 
and various economic and trade sanctions regulations administered by the U.S. Treasury Department’s Office of Foreign Assets Controls. Exports of our 
drug candidates outside of the U.S. must be made in compliance with these laws and regulations. If we fail to comply with these laws and regulations, we 
and certain of our employees could be subject to substantial civil or criminal penalties, including the possible loss of export or import privileges; fines, 
which may be imposed on us and responsible employees or managers; and, in extreme cases, the incarceration of responsible employees or managers.
In addition, changes in our drug candidates or changes in applicable export or import laws and regulations may create delays in the introduction, 
provision or sale of our drug candidates in international markets, prevent customers from using our drug candidates or, in some cases, prevent the export or 
import of our drug candidates to certain countries, governments or persons altogether. Any limitation on our ability to export, provide or sell our drug 
candidates could adversely affect our business, financial condition and results of operations.
Our activities subject us to various laws relating to U.S. and foreign investment, including the Outbound Investment Security Program, and our failure 
to comply with these laws could subject us to substantial fines, penalties and even injunctions, the imposition of which on us could have a material 
adverse effect on the success of our business.
The Outbound Investment Security Program (“OISP”), issued to implement the “Executive Order on Addressing United States Investments in Certain 
National Security Technologies and Products in Countries of Concern”, took effect on January 2, 2025. The OISP prohibits or requires notification of 
certain transactions involving U.S. persons and persons with a qualifying nexus to China (including Hong Kong and Macau) and specified covered 
activities in the semiconductors and microelectronics, quantum information technology, and artificial intelligence sectors (“covered transactions”). The 
OISP is a highly complex program with the potential for broad application, even with respect to entities and transactions outside of China.
The OISP may impact certain of the Company’s activities, including with respect to the issuance of securities, strategic mergers and acquisitions, 
investments, and possibly other business activities. Further, the OISP is likely to result in increased compliance burden and costs, which could adversely 
affect the Company. Violations of the OISP may subject the Company or affiliated U.S, persons to civil or criminal penalties, government investigations, 
business disruption, and reputational harm.
Any failure to comply with applicable regulations and industry standards or obtain various licenses and permits could harm our reputation and our 
business, results of operations and prospects.
A number of governmental agencies or industry regulatory bodies in the United States and other applicable jurisdictions impose strict rules, 
regulations and industry standards governing biopharmaceutical research and development activities, which apply to us. Our or our CROs’ failure to 
comply with such regulations could result in the termination of ongoing research, administrative penalties imposed by regulatory bodies or the 
disqualification of data for submission to regulatory authorities. This could harm our business, reputation, prospects for future work and results of 
operations. For example, if we or our CROs were to treat research animals inhumanely or in violation of international standards set out by the Association 
for Assessment and Accreditation of Laboratory Animal Care, it could revoke any such accreditation and the accuracy of our animal research data could be 
questioned.
If we or our CROs or other contractors or consultants fail to comply with environmental, health and safety laws and regulations, we could become 
subject to fines or penalties or incur costs that could have a material adverse effect on the success of our business.
We and third parties, such as our CROs or other contractors or consultants, are subject to numerous environmental, health and safety laws and 
regulations, including those governing laboratory procedures and the handling, use, storage, treatment and disposal of hazardous materials and wastes. Our 
operations involve the use of hazardous and flammable materials, including chemicals and 

 
40
Table of Contents
radioactive and biological materials. Our operations also produce hazardous waste products. We generally contract with third parties for the disposal of 
these materials and wastes. We cannot eliminate the risk of contamination or injury from these materials. In the event of contamination or injury resulting 
from our use of hazardous materials, we could be held liable for any resulting damages, and any liability could exceed our resources. We also could incur 
significant costs associated with civil or criminal fines and penalties.
Although we maintain workers’ compensation insurance to cover us for costs and expenses we may incur due to injuries to our employees resulting 
from the use of or exposure to hazardous materials, this insurance may not provide adequate coverage against potential liabilities. We do not maintain 
insurance for environmental liability or toxic tort claims that may be asserted against us in connection with our storage, use or disposal of biological, 
hazardous or radioactive materials.
In addition, we may be required to incur substantial costs to comply with current or future environmental, health and safety laws and regulations. 
These current or future laws and regulations may impair our research, development or production efforts. Failure to comply with these laws and regulations 
also may result in substantial fines, penalties or other sanctions.
If we face allegations of non-compliance with laws and encounter sanctions, our reputation, revenues and liquidity may suffer, and our drug 
candidates and future drugs could be subject to restrictions or withdrawal from the market.
Any government investigation of alleged violations of laws could require us to expend significant time and resources in response, and could generate 
negative publicity. Any failure to comply with ongoing regulatory requirements may significantly and adversely affect our ability to commercialize and 
generate revenues from our drugs. If regulatory sanctions are applied or if regulatory approval is withdrawn, the value of our company and our operating 
results will be adversely affected. Additionally, if we are unable to generate revenues from our product sales, our potential for achieving profitability will 
be diminished and the capital necessary to fund our operations will be increased.
If our information technology systems or those third parties with whom we work or our data, are or were compromised, we could experience adverse 
consequences resulting from such compromise, including but not limited to regulatory investigations or actions; litigation; fines and penalties; 
disruptions of our business operations; reputational harm; loss of revenue or profits; and other adverse consequences.
In the ordinary course of our business, we and the third parties with whom we work, process proprietary, confidential, and sensitive data, including 
personal data (such as health-related data), intellectual property, trade secrets and other sensitive data, e.g., business plans, transactions, financial 
information, etc. (collectively, sensitive information). Cyber-attacks, malicious internet-based activity, online and offline fraud, and other similar activities 
threaten the confidentiality, integrity, and availability of our sensitive information and information technology systems, and those of the third parties with 
whom we work. Such threats are prevalent and continue to rise, are increasingly difficult to detect, and come from a variety of sources, including traditional 
computer “hackers,” threat actors, “hacktivists,” organized criminal threat actors, personnel (such as through theft or misuse), sophisticated nation states, 
and nation-state-supported actors. 
We and the third parties with whom we work are subject to a variety of evolving threats, including but not limited to social-engineering attacks 
(including through deep fakes, which may be increasingly more difficult to identify as fake, and phishing attacks), malicious code (such as viruses and 
worms), malware (including as a result of advanced persistent threat intrusions), denial-of-service attacks, credential stuffing attacks, credential harvesting, 
personnel misconduct or error, ransomware attacks, supply-chain attacks, software bugs, server malfunctions, software or hardware failures, loss of data or 
other information technology assets, adware, telecommunications failures, earthquakes, fires, floods, attacks enhanced or facilitated by artificial 
intelligence (“AI”), and other similar threats. In particular, severe ransomware attacks are becoming increasingly prevalent and can lead to significant 
interruptions in our operations, ability to provide our products or services, loss of sensitive data and income, reputational harm, and diversion of funds. 
Extortion payments may alleviate the negative impact of a ransomware attack, but we may be unwilling or unable to make such payments due to, for 
example, applicable laws or regulations prohibiting such payments.
It may be difficult and/or costly to detect, investigate, mitigate, contain, and remediate a security incident. Our efforts to do so may not be successful. 
Actions taken by us or the third parties with whom we work to detect, investigate, mitigate, contain, and remediate a security incident could result in 
outages, data losses, and disruptions of our business. Threat actors may also gain access to other networks and systems after a compromise of our networks 
and systems.
We rely on third parties to operate critical business systems to process sensitive information in a variety of contexts, including, without limitation, 
cloud-based infrastructure, data center facilities, encryption and authentication technology, employee email, content delivery to customers, and other 
functions. Our ability to monitor these third parties’ information security practices is limited, and these third parties may not have adequate information 
security measures in place. If the third parties with whom we work experience a security incident or other interruption, we could experience adverse 
consequences. While we may be entitled to damages if the third parties with 

 
41
Table of Contents
whom we work fail to satisfy their privacy or security-related obligations to us, any award may be insufficient to cover our damages, or we may be unable 
to recover such award. In addition, supply-chain attacks have increased in frequency and severity, and we cannot guarantee that third parties’ infrastructure 
in our supply chain or that of the third parties with whom we work have not been compromised.
Although to our knowledge we have not experienced any material system failure or security breach to date, if such an event were to occur and cause 
interruptions in our operations, it could result in a material disruption of our development programs and our business operations. For example, the loss of 
clinical trial data from completed or future clinical trials could result in delays in our regulatory approval efforts and significantly increase our costs to
recover or reproduce the data. Likewise, we partially rely on our third-party research institution collaborators for research and development of our drug 
candidates and other third parties for the manufacture of our drug candidates and to conduct clinical trials, and similar events relating to their computer 
systems could also have a material adverse effect on our business.
If we (or a third party with whom we work) experience a security incident or are perceived to have experienced a security incident, we may 
experience material adverse consequences, such as government enforcement actions (for example, investigations, fines, penalties, audits, and inspections); 
additional reporting requirements and/or oversight; restrictions on processing sensitive information (including personal data); litigation (including class 
claims); indemnification obligations; negative publicity; reputational harm; monetary fund diversions; diversion of management attention; interruptions in 
our operations (including availability of data); financial loss; and other similar harms. Security incidents and attendant material consequences may prevent 
or cause customers to stop using our products, deter new customers from using our products, and negatively impact our ability to grow and operate our 
business. Our contracts may not contain limitations of liability, and even where they do, there can be no assurance that limitations of liability in our 
contracts are sufficient to protect us from liabilities, damages, or claims related to our data privacy and security obligations. We cannot be sure that our 
insurance coverage will be adequate or sufficient to protect us from or to mitigate liabilities arising out of our privacy and security practices, that such 
coverage will continue to be available on commercially reasonable terms or at all, or that such coverage will pay future claims.
To the extent that any disruption or security breach were to result in a loss of, or damage to, our data or applications, or inappropriate disclosure of 
confidential or proprietary information, we could incur liability and the further development and commercialization of our drug candidates could be 
delayed.
Any failure to comply with the various applicable laws and regulations related to data security, cybersecurity and personal information and privacy 
protection could affect our offshore offerings and lead to liabilities, penalties or other regulatory actions, which could have a material and adverse
effect on our business, financial condition and results of operations.
The regulatory framework for the collection, use, safeguarding, sharing, transfer and other processing of personal information worldwide is rapidly 
evolving and is likely to remain uncertain for the foreseeable future. Regulatory authorities in virtually every jurisdiction in which we operate have 
implemented and are considering a number of legislative and regulatory proposals concerning personal data protection.
In the United States, we are subject to laws and regulations that address privacy, personal information protection and data security at both the federal 
and state levels. Numerous laws and regulations, including security breach notification laws, health information privacy laws, and consumer protection 
laws, govern the collection, use, disclosure and protection of health-related and other personal information. Given the variability and evolving state of these 
laws, we face uncertainty as to the exact interpretation of the new requirements, and we may be unsuccessful in implementing all measures required by 
regulators or courts in their interpretation. For example, the federal Health Insurance Portability and Accountability Act of 1996, as amended by the Health 
Information Technology for Economic and Clinical Health Act (collectively, “HIPAA”), and their respective implementing regulations, imposes 
requirements relating to the privacy, security and transmission of individually identifiable health information. Among other things, the HIPAA, through its 
implementing regulations, makes certain of privacy and security standards directly applicable to business associates, defined as a person or organization, 
other than a member of a covered entity’s workforce, that creates, receives, maintains or transmits protected health information for or on behalf of a 
covered entity for a function or activity regulated by the HIPAA as well as their covered subcontractors.
In the past few years, numerous U.S. states-including California, Virginia, Colorado, Connecticut, and Utah-have enacted comprehensive privacy laws 
that impose certain obligations on covered businesses, including providing specific disclosures in privacy notices and affording residents with certain rights 
concerning their personal data. As applicable, such rights may include the right to access, correct, or delete certain personal data, and to opt-out of certain 
data processing activities, such as targeted advertising, profiling, and automated decision-making. The exercise of these rights may impact our business and 
ability to provide our products and services. Certain states also impose stricter requirements for processing certain personal data, including sensitive 
information, such as conducting data privacy impact assessments. These state laws allow for statutory fines for noncompliance. For example, the California 
Consumer Privacy Act of 2018, as amended by the California Privacy Rights Act of 2020 (“CPRA”) (collectively, “CCPA”) applies to personal 

 
42
Table of Contents
data of consumers, business representatives, and employees who are California residents, and requires businesses to provide specific disclosures in privacy 
notices and honor requests of such individuals to exercise certain privacy rights. The CCPA provides for fines of up to $7,500 per intentional violation and 
allows private litigants affected by certain data breaches to recover significant statutory damages. Similar laws are being considered in several other states, 
as well as at the federal and local levels, and we expect more states to pass similar laws in the future. These developments further complicate compliance 
efforts and increase legal risk and compliance costs for us and the third parties upon whom we rely. We may be subject to new laws governing the privacy 
of consumer health data. For example, Washington’s My Health My Data Act broadly defines consumer health data, places restrictions on processing 
consumer health data (including imposing stringent requirements for consents), provides consumers certain rights with respect to their health data, and 
creates a private right of action to allow individuals to sue for violations of the law. Other states are considering and may adopt similar laws. Additionally, 
under various privacy laws and other obligations, we may be required to obtain certain consents to process personal data. For example, some of our data 
processing practices may be challenged under wiretapping laws, if we obtain consumer information from third parties through various methods, including 
chatbot and session replay providers, or via third-party marketing pixels. These practices may be subject to increased challenges by class action plaintiffs. 
Our inability or failure to obtain consent for these practices could result in adverse consequences, including class action litigation and mass arbitration 
demands.
In Europe, regulatory authorities have implemented and are considering a number of legislative and regulatory proposals concerning data protection. 
For example, the General Data Protection Regulation (EU) 2016/679 (“GDPR”) imposes a broad range of strict requirements on companies, such as us, 
including requirements relating to having legal bases for processing personal information relating to identifiable individuals and transferring such 
information outside the European Economic Area (including to the United States) and providing details to those individuals regarding the processing of 
their personal information, keeping personal information secure. The GDPR substantially increases the penalties to which we could be subject in the event 
of any non-compliance, including fines of up to 10,000,000 Euros or up to 2% of our total worldwide annual turnover for certain comparatively minor 
offenses, or up to 20,000,000 Euros or up to 4% of our total worldwide annual turnover for more serious offenses. We face uncertainty as to the exact 
interpretation of the new requirements, and we may be unsuccessful in implementing all measures required by data protection authorities or courts in 
interpretation of the new law. National laws of member states of the European Union are in the process of being adapted to the requirements under the 
General Data Protection Regulation (EU) 2016/679. Because the General Data Protection Regulation (EU) 2016/679 specifically gives member states 
flexibility with respect to certain matters, national laws may partially deviate from this regulation and impose different obligations from country to country, 
leading to additional complexity and uncertainty.
Our employees and personnel may use generative AI technologies to perform their work, and the disclosure and use of personal data in generative AI 
technologies is subject to various privacy laws and other privacy obligations. Governments have passed and are likely to pass additional laws regulating 
generative AI. Our use of this technology could result in additional compliance costs, regulatory investigations and actions, and lawsuits. If we are unable 
to use generative AI, it could make our business less efficient and result in competitive disadvantages.
We may use AI/ Machine Learning (“ML”) to assist us in making certain decisions, which is regulated by certain privacy laws. Due to inaccuracies or 
flaws in the inputs, outputs, or logic of the AI/ML, the model could be biased and could lead us to make decisions that could bias certain individuals (or 
classes of individuals), and adversely impact their rights, employment, and ability to obtain certain pricing, products, services, or benefits.
We expect that we will continue to face uncertainty as to whether our efforts to comply with evolving obligations under global data protection, 
privacy and security laws will be sufficient. Any failure or perceived failure by us to comply with applicable laws and regulations could result in 
reputational damage or proceedings or actions against us by governmental entities, individuals or others. These proceedings or actions could subject us to 
significant civil or criminal penalties and negative publicity, result in the delayed or halted transfer or confiscation of certain personal information, require 
us to change our business practices, increase our costs and materially harm our business, prospects, financial condition and results of operations. In 
addition, our current and future relationships with customers, vendors, pharmaceutical partners and other third parties could be negatively affected by any 
proceedings or actions against us or current or future data protection obligations imposed on them under applicable laws, including the GPDR. In addition, 
a data breach affecting personal information, including health information, could result in significant legal and financial exposure and reputational damage 
that could potentially have an adverse effect on our business.
A severe or prolonged downturn in the United States or global economy could materially and adversely affect our business and financial condition.
COVID-19 had a severe and negative impact on the United States and the global economy from 2020 through 2022, and the global macroeconomic 
environment still faces numerous challenges. The Federal Reserve and other central banks have raised interest rates. The Russia-Ukraine conflict, the 
conflict in the Middle East and the attacks on shipping in the Red Sea have heightened geopolitical tensions across the world. The impact of the Russia-
Ukraine conflict on Ukraine food exports has contributed to increases in food prices and thus to inflation more generally. There have also been concerns
about the relationship between the United States and other countries 

 
43
Table of Contents
which may potentially have economic effects. Economic conditions in the United States are sensitive to global economic conditions, as well as changes in 
domestic economic and political policies and the expected or perceived overall economic growth rate in the United States. Any severe or prolonged 
slowdown in the global or the United States economy may materially and adversely affect our business, results of operations and financial condition.
Any of these factors and other factors beyond our control could have an adverse effect on the overall business sentiment and environment, cause 
uncertainties in the regions where we conduct business, cause our business to suffer in ways that we cannot predict and materially and adversely impact our 
business, financial conditions and results of operations.
Our business and results of operations could be adversely affected by public health crisis and natural catastrophes or other disasters outside of our 
control in the locations in which we, our suppliers, CROs, contract manufacturing organizations and other contractors operate.
Natural disasters, acts of war or terrorism, health epidemics, or other factors beyond our control may adversely affect the economy, infrastructure and 
livelihood of the people in the regions where we conduct our business. In addition to the impact of COVID-19, global pandemics in the locations in which 
we, our suppliers, CROs, contract manufacturing organizations and other contractors operate, or fear of spread of contagious diseases, such as avian 
influenza, severe acute respiratory syndrome (SARS), influenza A (H1N1), Ebola or another epidemic could disrupt the business operations of our 
company, our suppliers, CROs, contract manufacturing organizations and other contractors. Our operations may also be under the threat of floods, 
earthquakes, sandstorms, snowstorms, fire or drought, power, water or fuel shortages, failures, malfunction and breakdown of information management 
systems, unexpected maintenance or technical problems, or may be susceptible to potential wars or terrorist attacks. Serious natural disasters may result in 
loss of lives, injury, destruction of assets and disruption of our business and operations. Acts of war or terrorism may also injure our employees, cause loss 
of lives, disrupt our business network and destroy our markets. 
The occurrence of any of the foregoing events is beyond our control but may result in regional or global economic distress, which may materially and 
adversely affect our business, financial condition and results of operations.
We have identified material weaknesses in our internal control related to ineffective information technology general controls which could, if not 
remediated, result in material misstatements in our financial statements.
In connection with the preparation of our financial statements as of December 31, 2024, we concluded there are material weaknesses in our internal 
control related to ineffective information technology general controls (“ITGCs”). Notwithstanding, we have also concluded that the material weaknesses 
did not result in any identified misstatements to the consolidated financial statements, and there were no changes to previously released financial results. To 
remediate our material weaknesses, we have been implementing and will continue to implement measures designed to ensure that control deficiencies 
contributing to the material weaknesses are remediated, such that these controls are designed, implemented, and operating effectively. If our remedial 
measures are insufficient to address the material weaknesses, or if additional material weaknesses or significant deficiencies in our internal control over 
financial reporting are discovered or occur in the future, our financial statements may contain material misstatements and we could be required to restate 
our financial results.
We are in the process of designing and implementing measures to improve our internal control over financial reporting to remediate these material 
weaknesses. While we are designing and implementing measures to remediate these material weaknesses, we cannot predict the success of such measures 
or the outcome of our assessment of these measures at this time. We can give no assurance that these measures will remediate the deficiencies in internal 
control or that additional material weaknesses or any significant deficiencies in our internal control over financial reporting will not be identified in the 
future. If we fail to establish and maintain adequate internal controls, we could suffer material misstatements in our financial statements and fail to meet our 
reporting obligations, which would likely cause investors to lose confidence in our reported financial information. This could limit our access to capital 
markets, adversely affect our results of operations and lead to a decline in the trading price of our ADSs. Additionally, ineffective internal controls could 
expose us to an increased risk of fraud or misuse of corporate assets and subject us to potential delisting from the stock exchange on which we list or to 
other regulatory investigations and civil or criminal sanctions. We could also be required to restate our historical financial statements. For more information 
see “Item 15. Controls and Procedures— Management’s Annual Report on Internal Control over Financial Reporting.”
We may be subject to material litigation and regulatory proceedings.
We may be subject to litigation relating to securities law class actions, third-party and principal intellectual property infringement claims, claims 
relating to data and privacy protection, contractual agreements, employment related cases and other matters in the ordinary course of our business. For 
details of the material legal proceedings that we are subject to, see “Item 8. Financial Information—A. Consolidated Statements and Other Financial 
Information—Legal Proceedings.” Laws, rules and regulations may vary in their scope

and laws and regulations outside the United States may impose requirements that are more stringent than, or which conflict with, those in the United States. 
We have acquired and may acquire companies that may become subject to litigation, as well as regulatory proceedings. In connection with our prior 
investment in TJBio Hangzhou, we through I-Mab Biopharma Hong Kong Limited (“I-Mab Hong Kong”) were obligated to repurchase the equity held by 
any then-existing shareholder in TJBio Hangzhou by cash upon the occurrence of certain triggering events. In connection with the divestiture of our 
Greater China assets and business operations, we have transferred the equity interests we held in TJBio Hangzhou to certain participating shareholders of 
TJBio Hangzhou in exchange for extinguishment of the existing repurchase obligations owed by I-Mab Hong Kong to those shareholders in the amount of 
approximately $183 million. However, certain non-participating shareholders of TJBio Hangzhou initiated legal proceedings against I-Mab Hong Kong and 
our company in connection with the aforementioned transaction. On January 31, 2024, the non-participating shareholders of TJBio Hangzhou, commenced 
arbitration against I-Mab Hong Kong before China International Economic and Trade Arbitration Commission Zhejiang Sub-Commission. These non-
participating shareholders sought monetary relief amounting to $17.4 million as of January 29, 2024 in total and an order that I-Mab Hong Kong pay all 
arbitration fees and property preservation fees incurred by them. The arbitration proceedings were concluded and I-Mab settled with the non-participating 
shareholders in the second half of 2024. In addition, in connection with litigation or regulatory proceedings we may be subject to in various jurisdictions, 
we may be prohibited by laws, regulations or government authorities in one jurisdiction from complying with subpoenas, orders or other requests from 
courts or regulators of other jurisdictions, including those relating to data held in or with respect to persons in these jurisdictions. Our failure or inability to 
comply with the subpoenas, orders or requests could subject us to fines, penalties or other legal liability, which could have a material adverse effect on our 
reputation, business, results of operations and the trading price of our ADSs.
As a publicly listed company, we and certain of our subsidiaries face additional exposure to claims and lawsuits. We will need to defend against these 
lawsuits, including any appeals should our initial defense be successful. The litigation process may utilize a material portion of our cash resources and 
divert management’s attention away from the day-to-day operations of our company, all of which could harm our business. There can be no assurance that 
we will prevail in any of these cases, and any adverse outcome of these cases could have a material adverse effect on our reputation, business and results of 
operations. In addition, although we have obtained directors’ and officers’ liability insurance, the insurance coverage may not be adequate to cover our 
obligations to indemnify our directors and officers, fund a settlement of litigation in excess of insurance coverage or pay an adverse judgment in litigation.
The existence of litigation, claims, investigations and proceedings may harm our reputation, limit our ability to conduct our business in the affected 
areas and adversely affect the trading price of our ADSs. The outcome of any claims, investigations and proceedings is inherently uncertain, and in any 
event defending against these claims could be both costly and time-consuming, and could significantly divert the efforts and resources of our management 
and other personnel. An adverse determination in any litigation, investigation or proceeding could cause us to pay damages, incur legal and other costs, 
limit our ability to conduct business or require us to change the manner in which we operate.
Negative publicity with respect to us, our management, employees, business partners, affiliates, or our industry, may materially and adversely affect our 
reputation, business, results of operations and prospect.
Our reputation is vulnerable to many threats that can be difficult or impossible to control, and costly or impossible to remediate. Negative publicity 
about us, such as alleged misconduct or improper activities, or negative rumors relating to us, our management, employees, business partners or affiliates, 
can harm our business and results of operations, even if they are unsubstantiated or are satisfactorily addressed. Any regulatory inquiries or investigations 
or other actions against our management, any perceived unethical, fraudulent, or inappropriate business conduct by us or perceived wrong-doing by any 
key member of our management team or other employees, our business partners or our affiliates, could harm our reputation and materially adversely affect 
our business. Regardless of the merits or final outcome of any such regulatory inquiries or investigations or other actions, our reputation may be 
substantially damaged, which may impede our ability to attract and retain talents and business partners and develop our business.
Any negative publicity concerning us, our affiliates or any entity that shares the “I-Mab” name, including the divested PRC subsidiaries, even if 
untrue, could adversely affect our reputation and business prospects. There can be no assurance that negative publicity about us or any of our affiliates or 
any entity that shares the “I-Mab” name would not damage our brand image or have a material adverse effect on our business, results of operations and 
financial condition.

Moreover, any negative media publicity about the biopharmaceutical industry in general or product or service quality problems of other companies in 
the industry, including our peers, may also negatively impact our reputation. If we are unable to maintain a good reputation, our ability to attract and retain 
key employees and business partners could be harmed which in turn may materially and adversely affect our business, results of operations and prospect.
We face risks associated with the divestiture of our Greater China assets and business operations to TJBio Hangzhou. 
On February 6, 2024, we entered into definitive agreements to divest our Greater China assets and business operations, including the rights to the 
Greater China portfolio, to TJBio Hangzhou for an aggregate consideration of the RMB equivalent of up to $80 million, contingent on the achievement of 
certain future regulatory and sales-based milestone events. The divestiture transaction was closed in April 2024. After the completion of the divestiture, we 
do not own any rights to the Greater China portfolio, including the Greater China rights for eftansomatropin alfa, felzartamab, uliledlimab, and givastomig. 
We no longer bear future development costs of the Greater China assets and business operations. As a result of the divestiture, we have ceased to 
consolidate the divested entity, assets and businesses as well as their corresponding financial results from the second quarter of 2024. In light of that, our 
financial condition and results of operations have been materially affected and our historical results will not be indicative of future financial condition or 
results of operations.
There is no assurance that we may achieve anticipated strategic benefits through the divestiture. We may experience negative reactions as a result of 
the divestiture. There is no assurance that we will be able to collect part or all of the contingent consideration upon the occurrence of triggering events or 
potential royalties. Moreover, we cannot assure our investors that the divestiture will not be challenged by governmental authorities or private parties. We 
may be subject to litigation or other proceedings in connection with, or as a result of the divestiture, which may divert resources and management attention 
and harm our reputation, and may subject us to significant consequences, including fines, indemnification of the buyers and reversal of the divestiture.
We are subject to changing law and regulations regarding regulatory matters, corporate governance and public disclosure that have increased both our 
costs and the risk of non-compliance.
We are or will be subject to rules and regulations by various governing bodies, including, for example, the SEC, which is charged with the protection 
of investors and the oversight of companies whose securities are publicly traded, and the various regulatory authorities in the United States, the Cayman 
Islands and China, and to new and evolving regulatory measures under applicable law. Our efforts to comply with new and changing laws and regulations 
have resulted in and are likely to continue to result in, increased administrative expenses and a diversion of management time and attention from revenue-
generating activities to compliance activities.
Moreover, because these laws, regulations and standards are subject to varying interpretations, their application in practice may evolve over time as 
new guidance becomes available. This evolution may result in continuing uncertainty regarding compliance matters and additional costs necessitated by 
ongoing revisions to our disclosure and governance practices. If we fail to address and comply with these regulations and any subsequent changes, we may 
be subject to penalty and our business may be harmed.
Risks Related to Doing Business in China
We are subject to China’s data privacy and cybersecurity laws, regulations and guidelines and any other future laws and regulations, which may entail 
significant compliance costs and adversely affect our business.
Following the divestiture of our Greater China assets and business operations, we use a limited number of third-party data centers in China to host our 
servers. As a result, we are subject to China’s data privacy and cybersecurity laws, regulations and guidelines. In China, regulatory authorities have 
implemented and are considering a number of legislative and regulatory proposals concerning data protection. For example, China’s Cyber Security Law, 
which became effective in June 2017, created China’s first national-level data protection for “network operators,” which may include all organizations in 
China that provide services over the internet or another information network. The Data Security Law, which became effective in September 2021, among 
other things, provides for a security review procedure for the data activities that may affect national security. In addition, the Civil Code of the PRC, which 
became effective on January 1, 2021, expressly provides the right of privacy and personal information protection. The PRC Cyber Security Law, the Data 
Security Law and Civil Code are relatively new and subject to interpretation by the regulators. Although we only gain access to user information that is 
necessary for, and relevant to, the businesses conducted, the data we obtain and use may include information that is deemed as “personal information” or 
“important data” under the PRC Cyber Security Law, the Civil Code and related data privacy and protection laws and regulations.
In addition, certain industry-specific laws and regulations affect the collection and transfer of personal data in China. For example, Regulations on the 
Administration of Human Genetic Resources, effective in July 2019, the latest amended edition of which came into effect on May 1, 2024, require approval 
from the Science and Technology Administration Department of the State Council where human 

 
46
Table of Contents
genetic resources are involved in any international collaborative project and additional approval for any export or cross-border transfer of the samples of 
human genetic resources or associated data. It is possible that these laws may be interpreted and applied in a manner that is inconsistent with our practices, 
potentially resulting in confiscation of samples of human genetic resources and associated data, administrative fines and criminal liabilities.
Furthermore, in December 2021, the CAC and several other authorities jointly promulgated the revised Cybersecurity Review Measures, which came 
into effect in February 2022. Pursuant to the Cybersecurity Review Measures, a critical information infrastructure operator that purchases network products 
and services, or an internet platform operator that conducts data processing activities, shall be subject to cybersecurity review if it affects or may affect 
national security. In addition, internet platform operators processing personal information of more than one million users seeking to be listed on foreign 
stock markets must apply for a cybersecurity review. On August 30, 2024, the PRC State Council published the Regulation on Internet Data Security 
Management which came into effect in January 2025, which provides that data processors conducting the activities that affect or may affect national 
security shall apply for cybersecurity review. There have been no clarifications from the authorities as of the date of this annual report as to the standards 
for determining such activities that “affect or may affect national security.” As of the date of this annual report, (i) no detailed rules or implementation 
relating to the Cybersecurity Review Measures has been issued by any PRC regulatory authorities, (ii) we have not been informed of being identified as a 
critical information infrastructure operator or an internet platform operator, nor have we been required to go through the cybersecurity review procedures, 
by any PRC governmental authorities, and (iii) we have not been involved in any investigations on cybersecurity review on such basis, nor have we 
received any inquiry, notice, warning, or sanctions in such respect, by any PRC governmental authorities. Taking into consideration the above and that (i) 
the preclinical and clinical data processed or handled by us in our business operations, either by its nature or in scale, do not and will not directly or 
indirectly affect or potentially affect national security in any respect, and (ii) we have not possessed, and do not anticipate to possess, in the foreseeable 
future, personal information of more than one million users or persons, based on our understanding of the Cybersecurity Review Measures, we do not 
expect that we will be subject to cybersecurity review by the CAC in connection with our offering of securities to foreign investors and listing on the 
Nasdaq. Nevertheless, the exact scope of critical information infrastructure operator and “internet platform operator” under the current regulatory regime 
remains unclear, and the PRC governmental authorities may have wide discretion to decide the identification of critical information infrastructure operator 
as well as in the interpretation and enforcement of the Cybersecurity Review Measures and other laws, regulations and implementation rules. Therefore, it 
is uncertain whether we would be deemed as a critical information infrastructure operator or an internet platform operator thereunder.
Since 2022, the CAC also promulgated a series of rules and regulations on outbound data transfer, outlining the regulatory framework and providing 
detailed guidance. A data processor is subject to different regulatory requirements, depending on the nature, sensitivity and volume of the data to be 
transferred. See “Item 4.—Information on the Company—B. Business Overview—Regulation—PRC Regulation—Regulations Relating to Outbound Data 
Transfer.”
The PRC laws and regulations concerning data privacy and cybersecurity are continually evolving and not always clear, and the measures we take to 
comply with these laws, regulations and industry standards may not always be effective. We cannot assure our investors that we will comply with such 
laws and regulations regarding cybersecurity, information security, privacy and data protection in all respects and any failure or perceived failure to comply 
with these laws, regulations or policy may result in inquiries, penalties and other proceedings or actions against us by governmental authorities, such as 
warnings, fines, making certain required rectification, service suspension and/or other sanctions, as well as negative publicity and damage to our reputation. 
It also remains uncertain whether the future regulatory changes would impose additional restrictions on companies like us. We cannot predict the impact of 
the future regulatory changes, including impact of any draft measures, at this stage, and we will closely monitor and assess any development in the rule-
making process. If additional requirements are imposed to companies like us, such as the clearance of cybersecurity review, we face uncertainties as to 
whether we can fulfill those requirements in a timely manner, or at all. If we are not able to comply with the cybersecurity and data privacy requirements in 
a timely manner, or at all, we may be subject to government enforcement actions and investigations, fines, penalties or suspension of our non-compliant 
operations, which could materially and adversely affect our business and results of operations.
Uncertainties with respect to the PRC legal system could materially and adversely affect us.
The PRC legal system is a civil law system based on written statutes. Unlike the common law system, prior court decisions under the civil law system 
may be cited for reference but have limited precedential value. The overall effect of legislation over the past four decades has significantly enhanced the 
protections afforded to various forms of foreign investments in China. However, China has not developed a fully integrated legal system, and currently 
effective laws and regulations may not sufficiently cover all aspects of economic activities in China. Since these laws and regulations are relatively new 
and may be amended from time to time, and the PRC legal system continues to rapidly evolve, and because of the limited number of published decisions 
and the nonbinding nature of such decisions, and because the laws and regulations often give the regulator significant discretion in how to enforce them, the 
interpretations of many laws, regulations and rules may not be uniform and enforcement of these laws, regulations and rules involves uncertainties. These 
uncertainties may affect our judgment on the relevance of legal requirements and our ability to enforce our contractual rights or tort claims. Besides, 

 
47
Table of Contents
the PRC is geographically large and divided into various provinces and municipalities and, as such, different laws, rules, regulations and policies may have 
different and varying applications and interpretations in different parts of the PRC. Legislation or regulations, particularly in local applications, may be 
enacted without sufficient prior notice or announcement to the public. In addition, the regulatory uncertainties may be exploited through unmerited or 
frivolous legal actions or threats in attempts to extract payments or benefits from us. Furthermore, the PRC legal system is based in part on government 
policies and internal rules, some of which are not published on a timely basis, or at all, and may have a retroactive effect. As a result, we may not be aware 
of our violation of any of these policies and rules until sometime after the violation. Agreements that are governed by PRC laws may be more difficult to 
enforce by legal or arbitral proceedings in the PRC than that in other countries with different legal systems. In addition, any administrative and court 
proceedings in China may be protracted, resulting in substantial costs and diversion of resources and management attention.
The ability of U.S. authorities to bring actions for violations of U.S. securities law and regulations against us or our directors may be limited. 
Therefore, our investors may not be afforded the same protection as provided to investors in U.S. domestic companies.
The SEC, the U.S. Department of Justice and other U.S. authorities often have substantial difficulties in bringing and enforcing actions against non-
U.S. companies and non-U.S. persons. Due to jurisdictional limitations, matters of comity and various other factors, the SEC, the U.S. Department of 
Justice and other U.S. authorities may be limited in their ability to pursue bad actors, including in instances of fraud, in emerging markets such as China. A 
majority of our directors reside outside of the United States. There are significant legal and other obstacles for U.S. authorities to obtain information needed 
for investigations or litigation against us or our directors in case we or any of these individuals engage in fraud or other wrongdoing. In addition, local 
authorities in China may be constrained in their ability to assist U.S. authorities and overseas investors in connection with legal proceedings. As a result, if 
we or our directors commit any securities law violation, fraud or other financial misconduct, the U.S. authorities may not be able to conduct effective 
investigations or bring and enforce actions against us, our directors or other gatekeepers. Therefore, our investors may not be able to enjoy the same 
protection provided by various U.S. authorities as it is provided to investors in U.S. domestic companies.
We may be restricted from transferring our scientific data abroad.
On March 17, 2018, the General Office of the PRC State Council promulgated the Measures for the Management of Scientific Data, which provide a 
broad definition of scientific data and rules for the management of scientific data. According to these measures, enterprises in China must seek 
governmental approval before any scientific data involving a state secret may be transferred abroad or to foreign parties. Further, any researcher conducting 
research funded, at least in part, by the PRC government is required to submit scientific data for management by the entity to which such researcher is 
affiliated before the data may be published in any foreign academic journal. Currently, as the term “state secret” is not clearly defined, there is no assurance 
that we can always obtain approvals for sending scientific data (such as the results of clinical trials conducted within China) abroad, or to our foreign 
partners in China.
If we are unable to obtain the necessary approvals in a timely manner, or at all, our research and development of drug candidates may be hindered, 
which may materially and adversely affect our business, results of operations, financial conditions and prospects. If the government authorities consider the 
transmission of our scientific data to be in violation of the requirements under the measures, we may be subject to specific administrative penalties imposed 
by those government authorities.
Changes in international trade policies and rising political tensions, particularly between the United States and China, may adversely impact our 
business and operating results.
The U.S. government has made statements and taken certain actions that may lead to potential changes to U.S. and international trade policies towards 
China, especially considering recent statements and actions of the Trump administration and China's reaction to such statements and actions. Rising trade 
and political tensions could reduce levels of trades, investments, technological exchanges and other economic activities between China and other countries, 
which would have an adverse effect on global economic conditions, the stability of global financial markets, and international trade policies.
While we have not started the commercialization of our drug candidates, any rising trade and political tensions or unfavorable government policies on 
international trade, such as capital controls or tariffs, may affect the demand for our drug products, the competitive position of our drug products, the hiring 
of scientists and other research and development personnel, and import or export of raw materials in relation to drug development, or prevent us from 
selling our drug products in certain countries. In particular, if any new tariffs, legislation and/or regulations are implemented, or if existing trade 
agreements are renegotiated or, especially, if the U.S. government continues to take retaliatory trade actions due to the recent U.S.-China trade and political 
tension or imposes additional tariffs on goods imported from other countries, such as the EU, such changes could have an adverse effect on our business, 
financial condition and results of operations. In addition, our results of operations could be adversely affected if any such tensions or unfavorable 
government trade policies harm the Chinese economy or the global economy in general.

Recent litigation and negative publicity surrounding companies with operations in China that are listed in the United States may result in increased 
regulatory scrutiny of us and negatively impact the trading price of the ADSs and could have a material adverse effect upon our business, including 
our results of operations, financial condition, cash flows and prospects.
We believe that litigation and negative publicity surrounding companies with operations in China that are listed in the United States have negatively 
impacted stock prices for such companies. Various equity-based research organizations have published reports on China-based companies after examining, 
among other things, their corporate governance practices, related party transactions, sales practices and financial statements that have led to special 
investigations and stock suspensions on national exchanges. Any similar scrutiny of us, regardless of its lack of merit, could result in a diversion of 
management resources and energy, potential costs to defend ourselves against rumors, decreases and volatility in the ADS trading price, and increased 
directors and officers insurance premiums and could have a material adverse effect upon our business, including our results of operations, financial 
condition, cash flows and prospects.
If relations between China and the United States deteriorate, our business, operating results and financial condition could be adversely affected.
At various times during recent years, the United States and China have had significant disagreements over monetary, economic, political, 
environmental and social issues, and future relations between these two countries may deteriorate. Various Chinese entities, including certain 
biotechnology companies and contract manufacturing organizations in China, have been or may become, the subject of trade restrictions, sanctions, and 
other regulatory requirements by the U.S. government, which could restrict or even prohibit the ability to work with such entities. Changes in political 
conditions and changes in the state of China-U.S. relations are difficult to predict and could adversely affect our business, operating results and financial 
condition. Any deterioration in political or trade relations could harm our business. We cannot predict what effect any changes in China-U.S. relations may 
have on our ability to access capital or effectively do business in the United States and China. For example, President Biden previously issued an Executive 
Order on Preventing Access to Americans’ Bulk Sensitive Personal Data and United States Government-Related Data by Countries of Concern that seeks 
to prohibit or restrict specific types of commercial transactions involving “bulk sensitive personal data,” including (1) personal identifiers; (2) personal 
financial data; (3) personal health data (as defined under HIPAA); (4) precise geolocation data; (5) biometric identifiers; and (6) human genomic data, 
between U.S. persons and “countries of concern,” including China. If there is no lawful manner for us to transfer such data to China, or if the requirements 
for a legally-compliant transfer are too onerous, we could face significant adverse consequences, including the interruption or degradation of our 
operations, the need to relocate part of or all of our business or data processing activities to other jurisdictions (such as the United States) at significant 
expense and increased exposure to regulatory actions.
Moreover, any political or trade controversies between the United States and China, whether or not directly related to our business, could cause 
investors to be unwilling to hold or buy our ADSs and consequently cause the trading price of our ADSs to decline. In addition, any adoption of more 
stringent rules or regulations in China related to monetary, economic, political, environmental or social issues, particularly as those matters relate to 
relations with the United States, could harm our business, financial condition or prospects.
General Risks Related to Our ADSs
We may not be able to maintain compliance with the continued listing requirements of Nasdaq.
Our ADSs are listed on Nasdaq. In order to maintain that listing, we must satisfy minimum financial and other requirements including, without 
limitation, a requirement that our closing bid price must not fall below $1.00 per ADS for 30 consecutive business days. On March 19, 2025, we received a 
notice from Nasdaq that we are not in compliance with Nasdaq’s Listing Rule 5450(a)(1), because the minimum bid price of our ADSs has been below 
$1.00 per share for 30 consecutive business days (the “Notice”). The Notice has no immediate effect on the listing or trading of our ADSs on The Nasdaq 
Global Market.
In accordance with Nasdaq Listing Rule 5810(c)(3)(A), we have 180 calendar days, or until September 15, 2025, to regain compliance with the 
minimum bid price requirement. To regain compliance, the closing bid price of our ADSs must be at least $1.00 per ADS for a minimum of 10 consecutive 
business days during this 180 calendar day grace period, unless Nasdaq exercises its discretion to extend this 10-day period. In the event we do not regain 
compliance with the minimum bid price requirement by September 15, 2025, we may be eligible for an additional 180 calendar day compliance period if 
we elect to transfer to The Nasdaq Capital Market. To qualify, we would be required to meet the continued listing requirement for market value of publicly 
held shares and all other initial listing standards for The Nasdaq Capital Market, with the exception of the minimum bid price requirement, and would need 
to provide written notice of its intention to cure the bid price deficiency during the second compliance period. However, if it appears to Nasdaq’s staff that 
we will not be able to cure the deficiency or if we are otherwise not eligible, Nasdaq would notify us that our securities would be subject to delisting. We 
may appeal any such determination to delist our securities, but there can be no assurance that any such appeal would be successful.

 
49
Table of Contents
We intend to monitor the closing bid price of our ADSs and assess potential actions to regain compliance with Nasdaq’s Listing Rule 5450(a)(1). 
However, there can be no assurance that we will be able to regain compliance with the minimum bid price requirement or that we will otherwise maintain 
compliance with other Nasdaq listing requirements. If we fail to regain and maintain compliance with the minimum bid price requirement or to meet the 
other applicable continued listing requirements in the future and Nasdaq decides to delist our ADSs, the delisting could adversely affect the market price 
and liquidity of our ADSs, reduce our ability to raise additional capital and result in operational challenges and damage to investor relations and market 
reputation.
The trading price of our ADSs may be volatile, which could result in substantial losses to our investors.
For the period from January 1, 2024 to April 2, 2025, the trading price of our ADSs ranged from $0.76 to $2.54 per ADS. The trading price of our 
ADSs can be volatile and 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 operations in the same industry that have listed their securities in the United States may affect the 
volatility in the price of and trading volumes for our ADSs. Some of these companies have experienced significant volatility. The trading performances of 
these companies’ securities may affect the overall investor sentiment towards other companies listed in the United States and consequently may impact the 
trading performance of our ADSs.
In addition to market and industry factors, the price and trading volume for our ADSs 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 a drug’s use, or 
changes or delays in the regulatory review process;
•
announcements of therapeutic innovations, new products, acquisitions, strategic relationships, joint ventures or capital commitments 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 drug candidates;
•
variations in the level of expenses related to our drug candidates or preclinical, clinical development and commercialization programs;
•
any intellectual property infringement actions in which we may become involved;
•
announcements concerning our competitors or the pharmaceutical industry in general;
•
variations in our results of operations;
•
announcements about our results of operations that are not in line with analyst expectations, the risk of which is enhanced because it is our policy 
not to give guidance on results of operations;
•
publication of operating or industry metrics by third parties, including government statistical agencies, that differ from expectations of industry 
or financial analysts;
•
changes in financial estimates by securities research analysts;
•
media reports, whether or not true, about our business, our competitors or our industry;
•
additions to or departures of our management;

 
50
Table of Contents
•
fluctuations of exchange rates between the U.S. dollar and the RMB or other currencies of the jurisdiction where our contractors are located;
•
release or expiry of lock-up or other transfer restrictions on our outstanding ordinary shares or ADSs;
•
sales or perceived potential sales of additional ordinary shares or ADSs by us, our executive officers and directors or our shareholders;
•
any share repurchase programs;
•
general economic and market conditions and overall fluctuations in the U.S. equity markets;
•
changes in accounting principles; and
•
changes or developments in the U.S., PRC or global regulatory environment.
In addition, the stock market, in general, and 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 ADSs, regardless of our actual operating performance. Further, the current volatility in the financial markets and related 
factors beyond our control may cause the market price of our ADSs to decline rapidly and unexpectedly.
We may face an increased risk of securities class action litigation.
Historically, securities class action litigation has often been brought against a company following a significant decline in the market price of its 
securities. This risk is especially relevant for us because biotechnology and biopharmaceutical companies have experienced significant share price 
volatilities in recent years. If we were to face lawsuits, it could lead to substantial costs and a distraction of management’s attention and resources, which 
could harm our business.
In the past, shareholders of a public company often brought securities class action suits against the company following periods of instability in the 
market price of that company’s securities. If we were involved in a class action suit, it could divert a significant amount of our management’s attention and 
other resources from our business and operations, which could harm our results of operations and require us to incur significant expenses to defend the suit. 
Any such class action suit, whether or not successful, could harm our reputation and restrict our ability to raise capital in the future. In addition, if a claim is 
successfully made against us, we may be required to pay significant damages, which could have a material adverse effect on our financial condition and 
results of operations.
If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, or if they adversely change 
their recommendations regarding our ADSs, the market price for our ADSs and trading volume could decline.
The trading market for our ADSs will depend in part on the research and reports that securities or industry analysts publish about us or our business. If 
research analysts do not establish and maintain adequate research coverage or if one or more of the analysts who covers us downgrades our ADSs or 
publishes inaccurate or unfavorable research about our business, the market price for our ADSs would likely decline. If one or more of these analysts cease 
coverage of our company or fail to publish reports on us regularly, we could lose visibility in the financial markets, which, in turn, could cause the market 
price or trading volume for our ADSs to decline.
Because we do not expect to pay dividends in the foreseeable future, our investors must rely on price appreciation of our ADSs for return on their 
investments.
We currently intend to retain most, if not all, of our available funds and any future earnings to fund the development and development of our business. 
As a result, we do not expect to pay any cash dividends in the foreseeable future. Therefore, our investors should not rely on an investment in our ADSs as 
a source for any future dividend income.
Our board of directors has complete discretion as to whether to distribute dividends, subject to our memorandum and articles of association and 
certain requirements of Cayman Islands law. 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, a Cayman Islands company may pay a dividend out of either profit or share premium 
account of the company, provided that in no circumstances may a dividend be paid out of share premium if this would result in the company being unable 
to pay its debts as they fall due in the ordinary course of business. Even if our board of directors decides to declare and pay dividends, the timing, amount 
and form of future dividends, if any, will depend 

 
51
Table of Contents
on 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 our 
investors’ investments in our ADSs will likely depend entirely upon any future price appreciation of our ADSs. There is no guarantee that our ADSs will 
appreciate in value or even maintain the price at which our investors purchased the ADSs. Our investors may not realize a return on their investment in our 
ADSs and they may even lose their entire investment in our ADSs.
Substantial future sales or perceived potential sales of our ADSs in the public market could cause the price of our ADSs to decline.
Sales of substantial amounts of our ADSs in the public market, or the perception that these sales could occur, could adversely affect the market price 
of our ADSs and could materially impair our ability to raise capital through equity offerings in the future. Certain holders of our ordinary shares may cause 
us to register the sale of their shares under the Securities Act. Registration of these shares under the Securities Act would result in ADSs 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 form of ADSs in the public market, or sales of securities held by our significant shareholders or any other shareholder or the availability of 
these securities for future sale could cause the price of our ADSs to decline.
The voting rights of holders of ADSs are limited by the terms of the deposit agreement, and our investors may not be able to exercise the same rights as 
our shareholders.
Holders of ADSs do not have the same rights as our shareholders. As holders of our ADSs, our investors will not have any direct rights to attend 
general meetings of our shareholders or to cast any votes at such meetings. As ADS holders, our investors will only be able to exercise the voting rights 
carried by the underlying ordinary shares indirectly by giving voting instructions to the depositary in accordance with the provisions of the deposit 
agreement. Under the deposit agreement, our investors may vote only by giving voting instructions to the depositary. Upon receipt of our investors voting 
instructions, the depositary will try, as far as is practicable, to vote the ordinary shares underlying their ADSs in accordance with their instructions. If we 
ask for our investors’ instructions, then upon receipt of their voting instructions, the depositary will try to vote the underlying ordinary shares in accordance 
with these instructions. If we do not instruct the depositary to ask for our investors’ instructions, the depositary may still vote in accordance with the 
instructions they give, but it is not required to do so. Our investors will not be able to directly exercise their rights to vote with respect to the underlying 
ordinary shares unless they withdraw the shares, and become the registered holder of such shares prior to the record date for the general meeting. When a 
general meeting is convened, our investors may not receive sufficient advance notice of the meeting to withdraw the shares underlying their ADSs and 
become the registered holder of such shares to allow them to attend the general meeting and to vote directly with respect to any specific matter or resolution 
to be considered and voted upon at the general meeting. In addition, under our memorandum and articles of association, for the purposes of determining 
those shareholders who are entitled to attend and vote at any general meeting, our directors may close our register of members and/or fix in advance a 
record date for such meeting, and such closure of our register of members or the setting of such a record date may prevent our investors from withdrawing 
the ordinary shares underlying their ADSs and becoming the registered holders of such shares prior to the record date, so that our investors would not be 
able to attend the general meeting or to vote directly. If we ask for our investors’ instructions, the depositary will notify them of the upcoming vote and will 
arrange to deliver our voting materials to them. We have agreed to give the depositary notice of shareholder meetings sufficiently in advance of such 
meetings. Nevertheless, we cannot assure our investors that they will receive the voting materials in time to ensure that they can instruct the depositary to 
vote the underlying ordinary shares represented by their ADSs. In addition, the depositary and its agents are not responsible for failing to carry out voting 
instructions or for their manner of carrying out our investors’ voting instructions. This means that our investors may not be able to exercise their rights to 
direct how the shares underlying their ADSs are voted, and they may have no legal remedy if the shares underlying their ADSs are not voted as they 
requested. In addition, in our investors capacity as an ADS holders, they will not be able to call a shareholders’ meeting. Except in limited circumstances, 
the depositary for our ADSs will give us a discretionary proxy to vote the ordinary shares underlying our investors’ ADSs if they do not vote at 
shareholders’ meetings, which could adversely affect our investors’ interests.
Under the deposit agreement for the ADSs, if our investors do not vote, the depositary will give us a discretionary proxy to vote the ordinary shares 
underlying their ADSs at shareholders’ meetings unless:
•
we have instructed the depositary that we do not wish a discretionary proxy to be given;
•
we have informed the depositary that there is substantial opposition as to a matter to be voted on at the meeting;
•
a matter to be voted on at the meeting would have an adverse impact on shareholders; or
•
the voting at the meeting is to be made on a show of hands.

Table of Contents
The effect of this discretionary proxy is that our investors cannot prevent our ordinary shares underlying their ADSs from being voted, except under 
the circumstances described above. This may make it more difficult for shareholders to influence the management of our company. Holders of our ordinary 
shares are not subject to this discretionary proxy.
Our investors’ rights to participate in any future rights offerings may be limited, which may cause dilution to their holdings.
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 investors in the United States unless we register both the rights and the securities to which the rights relate under the Securities Act or an exemption 
from the registration requirements is available. Under the deposit agreement, the depositary will not make rights available to our investors unless both the 
rights and the underlying securities to be distributed to ADS holders are either registered under the Securities Act or exempt 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 and we may not be able to establish a necessary exemption from registration under the Securities Act. 
Accordingly, our investors may be unable to participate in our rights offerings and may experience dilution in their holdings.
Our investors may not receive cash dividends if the depositary decides it is impractical to make them available to them.
The depositary will pay cash dividends on the ADSs only to the extent that we decide to distribute dividends on our ordinary shares or other deposited 
securities, and we do not have any present plan to pay any cash dividends on our ordinary shares in the foreseeable future. To the extent that there is a 
distribution, the depositary of our ADSs has agreed to pay to our investors the cash dividends or other distributions it or the custodian receives on our 
ordinary shares or other deposited securities after deducting its fees and expenses pursuant to the deposit agreement. Our investors will receive these 
distributions in proportion to the number of ordinary shares their ADSs represent. However, the depositary may, at its discretion, decide that it is 
inequitable or impractical to make a distribution available to any holders of ADSs. For example, the depositary may determine that it is not practicable to 
distribute certain property through the mail, or that the value of certain distributions may be less than the cost of mailing them. In these cases, the 
depositary may decide not to distribute such property to our investors.
Our investors may be subject to limitations on transfer of their ADSs.
Our investors’ ADSs are transferable on the books of the depositary. However, the depositary may close its transfer books at any time or from time to 
time when it deems expedient in connection with the performance of its duties. The depositary may close its books from time to time for a number of 
reasons, including in connection with corporate events such as a rights offering, during which time the depositary needs to maintain an exact number of 
ADS holders on its books for a specified period. The depositary may also close its books in emergencies, and on weekends and public holidays. 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.
ADSs holders may not be entitled to a jury trial with respect to claims arising under the deposit agreement, which could result in less favorable 
outcomes to the plaintiff(s) in any such action.
The deposit agreement governing the ADSs representing our ordinary shares provides that, subject to the depositary’s right to require a claim to be 
submitted to the federal or state courts in the City of New York have jurisdiction to hear and determine claims arising under the deposit agreement and in 
that regard, to the fullest extent permitted by law, ADS holders waive the right to a jury trial of any claim they may have against us or the depositary arising 
out of or relating to our shares, the ADSs or the deposit agreement, including any claim under the U.S. federal securities laws. Also, we may amend or 
terminate the deposit agreement without our investors’ consent. If our investors continue to hold their ADSs after an amendment to the deposit agreement, 
they agree to be bound by the deposit agreement as amended.
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 of the deposit agreement is not intended to be deemed a waiver by any holder or beneficial 
owner of ADSs of our or the depositary’s compliance with the U.S. federal securities laws and the rules and regulations promulgated thereunder.
If our investors or any other holders or beneficial owners of ADSs bring a claim against us or the depositary in connection with matters arising under 
the deposit agreement or the ADSs, including claims under U.S. federal securities laws, our investors or such other holder or beneficial owner may not be 
entitled to a jury trial with respect to such claims, which may have the effect of limiting and discouraging lawsuits against us and/or the depositary. If a 
lawsuit is brought against us and/or the depositary under the deposit

agreement, it may be heard only by a judge or justice of the applicable trial court, in which the trial would be conducted according to different civil 
procedures and may result in different outcomes than a trial by jury would have had, including results that could be less favorable to the plaintiff(s) in any 
such action.
Nevertheless, if this jury trial waiver provision is not enforced, to the extent a court action proceeds, it would proceed under the terms of the deposit 
agreement with a jury trial. No condition, stipulation or provision of the deposit agreement or ADSs serves as a waiver by any holder or beneficial owner of 
ADSs or by us or the depositary of compliance with any substantive provision of the U.S. federal securities laws and the rules and regulations promulgated 
thereunder.
Our investors may face difficulties in protecting their interests, and their ability to protect their rights through U.S. courts may be limited, because we 
are incorporated under Cayman Islands law.
We are an exempted company incorporated under the laws of the Cayman Islands with limited liability. Our corporate affairs are governed by our 
memorandum and articles of association, the Companies Act, Cap. 22 (Act 3 of 1961, as consolidated and revised) of the Cayman Islands, which we refer 
to as the Companies Act, and the common law of the Cayman Islands. The rights of shareholders to take action against our directors, actions by our 
minority shareholders and the fiduciary duties of our directors to us under Cayman Islands law are to a large extent governed by the common law of the 
Cayman Islands. The common law of the Cayman Islands is derived in part from comparatively limited judicial precedent in the Cayman Islands as well as 
from the common law of England, the decisions of whose courts are of persuasive authority, but are not binding, on a court in the Cayman Islands. The 
rights of our shareholders and the fiduciary duties of our directors under Cayman Islands law are not as clearly established as they would be under statutes 
or judicial precedent in some jurisdictions in the United States. In particular, the Cayman Islands has a less developed body of securities laws than the 
United States. Some U.S. states, such as Delaware, have more fully developed and judicially interpreted bodies of corporate law than the Cayman Islands. 
In addition, with respect to Cayman Islands companies, plaintiffs may face special obstacles, including those relating to jurisdiction and standing, in 
attempting to assert derivative claims in state or federal courts of the United States.
Shareholders of Cayman Islands exempted companies like us have no general rights under Cayman Islands law to inspect corporate records (except 
for our memorandum and articles of association, our register of mortgages and charges and special resolutions of our shareholders) or to obtain copies of 
lists of shareholders of these companies. Our directors have discretion under our articles of association to determine whether or not, and under what 
conditions, our corporate records may be inspected by our shareholders, but are not obliged to make them available to our shareholders. This may make it 
more difficult for our investors to obtain the information needed to establish any facts necessary for a shareholder motion or to solicit proxies from other 
shareholders in connection with a proxy contest.
As a result of all of the above, our public shareholders may have more difficulty in protecting their interests in the face of actions taken by 
management, members of the board of directors or controlling shareholders than they would as public shareholders of a company incorporated in the 
United States.
We have been advised by Harney Westwood & Riegels 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), the Cayman Islands Grand Court will at common law enforce final and conclusive in personam judgments of state and/or federal courts 
of the United States of America (the Foreign Court) of a debt or definite sum of money against the Company (other than a sum of money payable in respect 
of taxes or other charges of a like nature, a fine or other penalty (which may include a multiple damages judgment in an anti-trust action) or where 
enforcement would be contrary to public policy). The Grand Court of the Cayman Islands may also at common law enforce final and conclusive in 
personam judgments of the Foreign Court that are non-monetary against the Company, for example, declaratory judgments ruling upon the true legal owner 
of shares in a Cayman Islands company. The Grand Court will exercise its discretion in the enforcement of non-money judgments by having regard to the 
circumstances, such as considering whether the principles of comity apply. To be treated as final and conclusive, any relevant judgment must be regarded 
as res judicata by the Foreign Court. A debt claim on a foreign judgment must be brought within six years of the date of the judgment, and arrears of 
interest on a judgment debt cannot be recovered after six years from the date on which the interest was due. The Cayman Islands courts are unlikely to
enforce a judgment obtained from the Foreign Court under civil liability provisions of U.S. federal securities law if such a judgment is found by the courts 
of the Cayman Islands to give rise to obligations to make payments that are penal or punitive in nature. Such a determination has not yet been made by the 
Grand Court of the Cayman Islands. A Cayman Islands court may stay enforcement proceedings if concurrent proceedings are being brought elsewhere. A 
judgment entered in default of appearance by a defendant who has had notice of the Foreign Court’s intention to proceed may be final and conclusive 
notwithstanding that the Foreign Court has power to set aside its own judgment and despite the fact that it may be subject to an appeal the time-limit for 
which has not yet expired. The Grand Court may safeguard the defendant’s rights by granting a stay of execution pending any such appeal and may also 
grant interim injunctive relief as appropriate for the purpose of enforcement.

Table of Contents
Our memorandum and articles of association contain anti-takeover provisions that could discourage a third party from acquiring us and adversely 
affect the rights of holders of our ordinary shares and the ADSs.
Our memorandum and articles of association contain provisions to limit the ability of others to acquire control of our company or cause us to engage 
in change of control transactions. These provisions could have the effect of depriving our shareholders of an opportunity to sell their shares at a premium 
over prevailing market prices by discouraging third parties from seeking to obtain control of our company in a tender offer or similar transaction. Our board 
of directors has the authority to issue preferred shares in one or more series and to fix their designations, powers, preferences, privileges, and relative 
participating, optional or special rights and the qualifications, limitations or restrictions, including dividend rights, conversion rights, voting rights, terms of 
redemption and liquidation preferences, any or all of which may be greater than the rights associated with our ordinary shares, in the form of ADS or 
otherwise. Preferred shares could be issued with terms calculated to delay or prevent a change in control of our company or make removal of management 
more difficult. If our board of directors decides to issue preferred shares, the price of our ADSs may fall and the voting and other rights of the holders of 
our ordinary shares and ADSs may be materially and adversely affected.
We are a foreign private issuer within the meaning of the rules under the Exchange Act, and as such we are exempt from certain provisions applicable 
to U.S. domestic public companies.
Because we qualify as a foreign private issuer under the Exchange Act, we are exempt from certain provisions of the securities rules and regulations in 
the United States that are applicable to U.S. domestic issuers, including:
•
the rules under the Exchange Act requiring the filing with the SEC of quarterly reports on Form 10-Q or current reports on Form 8-K;
•
the sections of the Exchange Act regulating the solicitation of proxies, consents, or authorizations in respect of a security registered under the 
Exchange Act;
•
the sections of the Exchange Act requiring insiders to file public reports of their stock ownership and trading activities and liability for insiders 
who profit from trades made in a short period of time; and
•
the selective disclosure rules by issuers of material nonpublic information under Regulation FD promulgated by SEC.
We are required to file an annual report on Form 20-F within four months of the end of each fiscal year. In addition, we intend to publish our quarterly 
results as press releases, distributed pursuant to the rules and regulations of the Nasdaq Stock Market. Press releases relating to financial results and 
material events will also be furnished to the SEC on Form 6-K. However, the information we are required to file with or furnish to the SEC will be less 
extensive and less timely compared to that required to be filed with the SEC by U.S. domestic issuers. As a result, our investors may not be afforded the 
same protections or information that would be made available to them if they were investing in a U.S. domestic issuer. However, if we determine that we 
no longer meet the definition of a foreign private issuer in the future, we would become subject to the reporting requirements for a domestic issuer.
As an exempted company incorporated in the Cayman Islands, we are permitted to adopt certain home country practices in relation to corporate 
governance matters that differ significantly from the Nasdaq Stock Market’s corporate governance requirements; these practices may afford less 
protection to shareholders than they would enjoy if we complied fully with the Nasdaq Stock Market’s corporate governance requirements.
As a Cayman Islands company listed on the Nasdaq Stock Market, we are subject to the Nasdaq Stock Market’s corporate governance requirements. 
However, the Nasdaq Stock Market rules permit a foreign private issuer like us to follow the corporate governance practices of its home country. Certain 
corporate governance practices in the Cayman Islands, which is our home country, may differ significantly from the Nasdaq Stock Market’s corporate 
governance requirements. For example, neither the Companies Act nor our memorandum and articles of association requires a majority of our directors to 
be independent and we could include non-independent directors as members of our compensation committee and nominating committee, and our 
independent directors would not necessarily hold regularly scheduled meetings at which only independent directors are present. Currently, our board of 
directors consists of a majority of independent directors. We currently rely on foreign private issuer exemptions to Nasdaq Rules 5605(d) and 5605(e), as 
we have one member on each of our compensation committee and nominating and corporate governance committee that is not independent. Additionally, 
our home country practices provide that shareholder approval may not be required when a plan or other equity compensation arrangement is established or 
materially amended and that we are not required to hold an annual general meeting of shareholders no later than one year after the end of its fiscal year-end. 
As we have chosen, or may from time to time to choose, to follow home country practice exemptions with respect to certain corporate matters, such as the 
ones mentioned above, our shareholders

may be afforded less protection than they otherwise would under the Nasdaq Stock Market’s corporate governance requirements applicable to U.S. 
domestic issuers. See also “Item 16G. Corporate Governance.”
We believe that we were a passive foreign investment company for U.S. federal income tax purposes for the taxable year ended December 31, 2024, 
which could subject U.S. investors in our ADSs or ordinary shares to significant adverse U.S. federal income tax consequences.
We will be classified as a passive foreign investment company (“PFIC”), for any taxable year if either (i) 75% or more of our gross income for such 
year consists of certain types of “passive” income or (ii) 50% or more of the value of our assets (generally determined on the basis of a quarterly average) 
during such year produce or are held for the production of passive income. Based upon the nature and composition of our assets (in particular, the retention 
of substantial amounts of cash and investments) and income (in particular, the generation of interest income and lack of active income), and the market 
price of our ADSs, we believe that we were a PFIC for the taxable year ended December 31, 2024 and we will likely be a PFIC for our current taxable year 
unless the market price of our ADSs significantly increases and/or we invest a substantial amount of the cash and other passive assets we hold in assets that 
produce or are held for the production of active income. Because the determination of whether we are a PFIC for a taxable year is fact-intensive and made 
after the close of such taxable year applying principles and methodologies that in some circumstances are unclear and subject to varying interpretations, we 
cannot provide any assurances as to our PFIC status, and our U.S. counsel expresses no opinion with respect to our PFIC status.
If we are a PFIC in any taxable year, a U.S. Holder (as defined in “Item 10. Additional Information—E. Taxation—U.S. Federal Income Tax 
Considerations”) may incur significantly increased U.S. federal income tax on gain recognized on the sale or other disposition of the ADSs or ordinary 
shares and on the receipt of distributions on the ADSs or ordinary shares to the extent such gain or distribution is treated as an “excess distribution” under 
the U.S. federal income tax rules and such U.S. Holder may be subject to burdensome reporting requirements. Further, if we are a PFIC for any taxable 
year during which a U.S. Holder holds our ADSs or ordinary shares, we generally will continue to be treated as a PFIC for all succeeding years during 
which such U.S. Holder holds our ADSs or ordinary shares, unless we were to cease to be a PFIC and the U.S. Holder were to make a “deemed sale” 
election with respect to the ADSs or ordinary shares. For more information see “Item 10. Additional Information—E. Taxation—U.S. Federal Income Tax 
Considerations.”
If we (or any of our non-U.S. subsidiaries) are a controlled foreign corporation, certain of our U.S. investors may suffer adverse tax consequences.
If a “United States person” for U.S. federal income tax purposes is treated as owning (directly, indirectly, or constructively) at least 10% of the total 
value or total combined voting power of our stock, such person may be treated as a “United States shareholder,” or a U.S. Shareholder, with respect to each 
“controlled foreign corporation,” or CFC, in our group (if any). A non-U.S. corporation will be a CFC if U.S. Shareholders own (directly, indirectly, or 
constructively) more than 50% of the total value or total combined voting power of the stock of the non-U.S. corporation. Because our group includes one 
or more U.S. corporate subsidiaries, certain of our current or future non-U.S. corporate subsidiaries may be treated as CFCs (regardless of whether we are 
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 the CFC’s 
“Subpart F income,” “global intangible low-taxed income,” and investments of earnings in U.S. property (regardless of whether the CFC makes any 
distributions to its shareholders). Additionally, an individual U.S. Shareholder with respect to a CFC generally will not be allowed certain tax deductions or 
foreign tax credits that would be allowed to a corporate U.S. Shareholder. Failure to comply with CFC reporting obligations may subject a U.S. 
Shareholder to significant monetary penalties and prevent the statute of limitations from running with respect to the U.S. Shareholder’s U.S. federal income 
tax return for the taxable year in which reporting was due. There can be no assurance that we will assist our U.S. investors in determining whether we (or 
any of our current or future non-U.S. subsidiaries) are treated as a CFC or whether such U.S. investors are treated as U.S. Shareholders with respect to any 
such CFC, or that we will furnish to any such U.S. Shareholders information that may be necessary to comply with their CFC reporting and tax paying 
obligations. U.S. investors should consult their own tax advisors regarding the CFC rules’ impact in their particular circumstances.
Changes in tax laws or regulations that are applied adversely to us or our customers may have a material adverse effect on our business, cash flow, 
financial condition, or results of operations.
New tax laws, statutes, rules, regulations, or ordinances could be enacted at any time. Further, existing tax laws, statutes, rules, regulations, or 
ordinances could be interpreted differently, changed, repealed, or modified at any time. Any such enactment, interpretation, change, repeal, or modification 
could adversely affect us, possibly with retroactive effect. In particular, changes in corporate tax rates, the realization of net deferred tax assets, the taxation 
of income, including foreign earnings, and the deductibility of expenses could have a material impact on our financial position, including the value of our 
deferred tax assets, result in significant one-time charges, increase our future tax expenses, reduce net returns to our shareholders, and increase the 
complexity, burden, and cost of tax compliance.

ITEM 4. INFORMATION ON THE COMPANY
A.
History and Development of the Company
We commenced our operations in November 2014, when our predecessor Third Venture Biopharma (Nanjing) Co., Ltd was established.
I-Mab was established in June 2016 under the laws of the Cayman Islands as our offshore holding company. In July 2016, I-Mab established I-Mab 
Biopharma Hong Kong Limited, (“I-Mab Hong Kong”), as its intermediary holding company. In August 2016, I-Mab Hong Kong established a wholly-
owned PRC subsidiary, I-Mab Biopharma Co., Ltd. (later renamed to TJ Biopharma (Shanghai) Co. Ltd. and referred to herein as “TJBio Shanghai”). In 
September 2016, the assets and operations of Third Venture Biopharma (Nanjing) Co., Ltd were consolidated into TJBio Shanghai.
In July 2017, I-Mab Hong Kong acquired a controlling interest in I-Mab Bio-tech (Tianjin) Co., Ltd., (“I-Mab Tianjin”), formerly known as Tasgen 
Bio-tech (Tianjin) Co., Ltd., a company focused on the chemistry, manufacturing and controls of biologics in China. Through an internal corporate 
restructuring, I-Mab Tianjin became the 100% owner of TJBio Shanghai in September 2017 and I-Mab Hong Kong acquired the remaining interest in I-
Mab Tianjin in May 2018, becoming the 100% owner of I-Mab Tianjin.
In February 2018, I-Mab Biopharma US Limited (“I-Mab US”) was established in Maryland, United States as a wholly-owned subsidiary of I-Mab 
Hong Kong and as the hub for the discovery and development of the drug candidates in our Global portfolio.
On January 17, 2020, our ADSs commenced trading on the Nasdaq Global Market under the symbol “IMAB.”
In 2020, we invested in a comprehensive biologics manufacturing facility in Hangzhou, China as part of our strategic plan to become a specialty 
biopharma company. The construction of this facility commenced in April 2021. This facility established a pilot capacity of two production lines. The 
project was financed by a combination of internal and external sources. In September 2020, a group of domestic investors in China invested a total of $120 
million (in RMB equivalent) in cash. Upon the closing of this financing, we, through our wholly-owned subsidiary and parties acting in concert, were a 
majority shareholder of I-Mab Biopharma (Hangzhou) Co., Ltd. (later renamed TJ Biopharma (Hangzhou) Co., Ltd. and referred to herein as “TJBio 
Hangzhou”), the entity holding the facility in Hangzhou. On July 16, 2022, TJBio Hangzhou entered into a definitive financing agreement with a group of 
domestic investors in China to raise approximately $46 million (in RMB equivalent). Upon the closing of the financing, we, through our wholly-owned 
subsidiary, remained the largest shareholder of TJBio Hangzhou. Upon the occurrence of certain triggering events as specified in the shareholders 
agreement with TJBio Hangzhou, we became obligated to repurchase the equity held by other domestic investors in cash or in our securities if TJBio 
Hangzhou failed to accomplish certain public offering conditions. On February 6, 2024, in connection with the divestiture of our Greater China assets and 
business operations, we transferred the equity interests we held, through our wholly-owned subsidiary, in TJBio Hangzhou to certain participating 
shareholders of TJBio Hangzhou in exchange for the extinguishment of the existing repurchase obligations owed by I-Mab Hong Kong to those 
shareholders in the amount of approximately $183 million. We subsequently settled the remaining repurchase obligations of approximately $32 million 
through repurchase agreements with certain non-participating shareholders of TJBio Hangzhou by September 2024. Concurrently with the divestiture, we 
also participated in the Series C fundraising of TJBio Hangzhou with an additional investment of $19 million in the first quarter of 2024. See Note 7 – 
Investments and put right liabilities to our consolidated financial statements included elsewhere in this annual report for additional information of our
investment in TJBio Hangzhou. 
In October 2023, we divested the 51% equity interest in Zhejiang Tianli Pharmaceutical Sales Co., Ltd. previously held by I-Mab Biopharma Co., Ltd.
On February 6, 2024, we entered into definitive agreements with TJBio Hangzhou and a group of China-based investors to divest our Greater China 
assets and business operations. Pursuant to the definitive agreements, we transferred 100% of the outstanding equity interest in TJBio Shanghai, that 
operates our business in China, on a cash-free and debt-free basis, to TJBio Hangzhou for an aggregate consideration of the RMB equivalent of up to $80 
million, contingent on TJBio Hangzhou’s achievement of certain future regulatory and sales-based milestone events as well as royalties. We also retain a 
right of first negotiation outside of Greater China related to three future investigational new drug candidates.
Our principal executive offices are located at 2440 Research Boulevard, Suite 400, Rockville, MD 20850, the United States. Our telephone number at 
this address is (240) 745-6330.
Our registered office in the Cayman Islands is located at Vistra (Cayman) Limited, P.O. Box 31119 Grand Pavilion, Hibiscus Way, 802 West Bay

Business Overview
Executive Summary
We are a U.S.-based, global biotech company, focused on the development of precision immuno-oncology agents for the treatment of cancer. Our 
innovative immuno-oncology pipeline consists of three clinical stage programs, givastomig; uliledlimab; and ragistomig. We currently are pursuing one 
program internally, givastomig, a potential best-in-class CLDN18.2 bispecific antibody for the treatment of gastric cancer. Givastomig is currently being
studied in an ongoing Phase 1b study in combination with nivolumab and chemotherapy in first-line gastric cancer. We expect to provide an update on the 
dose escalation portion of the Phase 1b study in the second half of 2025 and an update on the dose expansion portion of the Phase 1b study in the first half 
of 2026. In connection with our Realignment Plan we have paused internal development of uliledlimab while we await further data from TJ Biopharma’s 
ongoing, randomized Phase 2 study combining uliledlimab with a checkpoint inhibitor in China. The results of these studies will help inform any potential 
future development path of uliledlimab. Our third program, ragistomig, is managed by our collaboration partner, ABL Bio, Inc., (“ABL Bio”), who is 
currently conducting an ongoing Phase 1 study in multiple solid tumors. The stage of development of our pipeline assets, including the progress in our 
ongoing clinical trials, is represented in the table below:

Notes: mNSCLC = metastatic non-small cell lung cancer; PD-(L)1 refers to inhibitors of PD-L1 or PD-1; Ab = antibody; mAb = monoclonal antibody; GC = gastric cancers; GEJ = 
gastroesophageal junction; EAC = esophageal adenocarcinoma cancer; 1L = first-line; PFS = progression free survival.
We made significant progress throughout the year in development of our global clinical pipeline assets: givastomig, uliledlimab, and ragistomig. 
Substantial achievements in 2024 included: 
1)
dosed the first patient in an ongoing, triplet combination, dose escalation study combining givastomig with nivolumab and chemotherapy 
(mFOLFOX6) in the first quarter of 2024; 
2)
presented data on ragistomig by I-Mab’s development partner, ABL Bio, at the 2024 American Society of Clinical Oncology (“ASCO 2024”) 
in June 2024 showing promising objective responses in patients with various solid tumors whose tumors progressed or recurred after prior 
standard treatments, including patients with prior exposure to PD-(L)1 inhibitors;
3)
entered into a clinical trial collaboration and supply agreement with Bristol Myers Squibb to support the further development of givastomig 
in combination with nivolumab and chemotherapy;

Givastomig (“TJ-CD4B”): A Novel 4-1BB Bispecific Antibody for CLDN18.2-Positive Gastric and Other Cancers
Summary
Givastomig (also known as “ABL111”, “TJ033721” and “TJCD4B”) is a bispecific antibody targeting Claudin18.2 (“CLDN18.2”), a tumor antigen 
preferentially expressed in gastric, esophageal, and pancreatic cancers, and 4-1BB, a co-stimulatory molecule on T cells adjacent to CLDN18.2-positive 
tumor cells. CLDN18.2 is a tight junction molecule normally restricted to epithelial cells of the gastric mucosa but becomes widely expressed on the cell 
surface in select tumors, such as gastric, esophageal, and pancreatic cancers, making it a highly attractive tumor target. Givastomig is being jointly 
developed through a global partnership with ABL Bio, in which we act as the lead party and we share worldwide rights (50/50), excluding Greater China 
and South Korea, equally with ABL Bio.
Givastomig has two key advantages over current CLDN18.2 antibodies and 4-1BB agonistic antibodies. First, givastomig, can bind to tumor cells even 
with low levels of CLDN18.2 expression, making it potentially applicable to a broader patient population with various expression levels of CLDN18.2. 
Second, only upon tumor cell engagement by givastomig are T cells stimulated by the 4-1BB antibody moiety, making the 4-1BB antibody arm only active 
at the tumor site. This localized T cell activation is conditional upon CLDN18.2 engagement and is expected to exert strong anti-tumor activity while 
minimizing systemic side effects such as liver toxicity commonly seen with 4-1BB agents in previous preclinical studies and clinical trials. In March 2022, 
we announced that the U.S. FDA granted givastomig Orphan Drug Designation for the treatment of gastric cancer, including gastroesophageal junction 
carcinoma.
In October 2023, we presented the topline Phase 1 data of givastomig with promising early efficacy signals, including patients with low levels of 
CLDN18.2 tumor expression, at the European Society for Medical Oncology (“ESMO”) annual meeting. Phase 1 dose escalation reached the highest 
planned dose level. Most treatment-related adverse events were low-grade. Positive monotherapy efficacy results were observed, including in tumors with
lower levels of CLDN18.2 expression, in patients with previously treated cancer that has relapsed or progressed after prior standard treatments.
In September 2024, we presented updated safety and expanded efficacy data from the Phase 1 trial of givastomig as monotherapy in CLDN18.2-
positive advanced gastroesophageal carcinoma (“GEC”), at ESMO 2024. An overall response rate (“ORR”) of 16.3% (7/43) was observed in a total of 43 
heavily pre-treated patients with CLDN18.2-positive (1+ intensity in ≥1% of cells) GEC, who received givastomig at doses ranging from 5 to 18 mg/kg. A 
favorable safety profile, with mainly grade 1 or 2 treatment-related adverse events (“TRAEs”) and no observations of dose-limiting toxicities (“DLTs”) or 
identification of a maximum tolerated dose (“MTD”) suggested the feasibility of further investigation of combinations with other agents.
In January 2025, based on monotherapy data with givastomig demonstrating clinical activity and a favorable toxicity and early encouraging efficacy 
data in the Phase 1b dose escalation study combining givastomig with front line, standard of care, nivolumab and chemotherapy, we announced a re-
prioritization of resources, with a focus on advancing givastomig as our lead clinical program. We are continuing to sponsor the Phase 1b dose escalation 
and dose expansion trials of givastomig in combination with nivolumab and chemotherapy in patients with CLDN18.2-positive (1+ intensity in ≥1% of 
cells) treatment-naïve gastric, gastroesophageal junction and esophageal cancer at United States based investigational sites. We believe front-line gastric 
cancer is an area of high unmet medical need, and the ability to combine a novel immunostimulant such as givastomig with standard of care therapies that 
include checkpoint

inhibitors and chemotherapy regimens has the potential to transform clinical care of these patients. In parallel, we are developing a CLDN18.2 
immunohistochemistry assay for patient selection and are exploring potential global partnership opportunities for givastomig.
Therapeutic Indications
Gastric cancer is one of the leading causes of cancer-related deaths worldwide. Treatment for advanced gastric, gastroesophageal junction, or 
esophageal adenocarcinoma often involves a combination of chemotherapy and now, immune therapies (checkpoint inhibitors). However, the clinical 
benefit remains modest with the current therapies. Therefore, there is a significant unmet medical need as most patients with metastatic cancer have a low 
survival rate.
According to epidemiology data provided by Data Monitor Biomed Tracker, the annual incidence of gastric cancer in the United States, France, 
Germany, Italy, Spain, the United Kingdom (formerly known as the “5 E.U.”), and Japan was estimated to be approximately 250,000 patients. Of these, we 
estimate based on screening data that approximately 78% or 195,000 patients are HER2-negative. Within that population it is estimated that approximately 
70% or 136,500 patients are CLDN18.2-positive. Our current clinical program focuses on HER2-negative, CLDN18.2-positive populations in gastric 
cancer.
Zolbetuximab-clzb (“zolbetuximab”) was recently approved by the FDA for first-line treatment of adults with locally advanced unresectable or 
metastatic HER2-negative gastric or gastro-esophageal junction adenocarcinoma whose tumors are CLDN18.2-positive in combination with chemotherapy. 
CLDN18.2 positivity is defined as ≥75% of tumor cells demonstrating moderate to strong membranous CLDN18 staining (2+ or 3+ intensity). While 
zolbetuximab provides an important option for patients with advanced gastric cancer, it is important to highlight the significant percentage of patients who 
are not eligible for zolbetuximab based on CLDN18.2 expression levels. There are no approved treatments for CLDN18.2 expression levels below 75%. 
This represents a large opportunity for CLDN18.2-directed therapeutic approaches that broaden the patient population across a wider range of CLDN18.2 
expression levels.
Markets include U.S., 5 E.U., and Japan in 2025 based on Data Monitor Biomed Tracker.

CLDN18.2 protein is not only highly expressed in gastric cancers but also detected at various levels in other tumor types. Therefore, givastomig in 
combination with other anti-cancer therapies may warrant further investigation based on the biological rationale and CLDN18.2 prevalence. In addition, 
givastomig may have potential benefits for early-stage cancers in the neoadjuvant setting. In essence, any stage and any tumor type that may have 
CLDN18.2 over expression and are treated with standard of care that involves a checkpoint inhibitor +/- chemotherapy.

Potential Differentiation of Givastomig
Givastomig is a novel bispecific antibody, with one arm targeting CLDN18.2 and the other targeting 4-1BB through conditional local activation. The 
key differentiation of givastomig is two-fold. First, it binds to tumors with a wide range of CLDN18.2 expression levels, as demonstrated in preclinical 
animal models. Second, the 4-1BB arm of givastomig is designed to function upon local tumor engagement as a mechanism of conditional immune 
activation. This feature makes givastomig a unique T cell activator only localized at the tumor site, reducing the risk of systemic toxicities, e.g., liver 
toxicity and systemic cytokine release, which are typically associated with 4-1BB. In support of the conditional activation, givastomig exhibits less 
gastrointestinal toxicity than is commonly observed for other CLDN18.2 targeted therapeutics.
Moreover, unlike previous generations of 4-1BB agonist antibodies with hepatotoxicity issues, givastomig binds to a distinct 4-1BB epitope that only 
triggers 4-1BB signaling upon CLDN18.2 target engagement but not Fc receptor interaction. This unique tumor-associated antigen-dependent property is 
expected to drastically reduce peripheral T cell activation and hepatic and systemic immunotoxicity without compromising anti-tumor activity. If proven in 
the clinic, these properties enable givastomig to be highly differentiated from other CLDN18.2-based compounds.

Schematic diagram of the overall structure of givastomig and its components. The 4-1BB agonistic antibody is a single-chain Fv connected to 
the C-terminus of a disabled Fc in a full anti-CLDN18.2 antibody via a flexible linker. The design allows the molecule to fit in the immune 
synapse (left) and trans-activate T cells only upon tumor cell binding.
As shown in the figure below, givastomig consistently exhibited stronger binding than the reference antibody zolbetuximab in cells with high, 
moderate, and even low levels of CLDN18.2.

The ability of givastomig to ligate 4-1BB and activate downstream signaling was tested in CLDN18.2-positive or negative target cells co-cultured 
with T cells as effectors. The results in the figure show that givastomig elicited the strongest 4-1BB-mediated NF-kB reporter activity, but only in the 
presence of CLDN18.2-positive cells and not CLDN18.2-negative cells. In contrast, urelumab (a first generation 4-1BB antibody) induced NF-kB reporter 
activity regardless of target cell CLDN18.2 expression. In another experiment where human peripheral blood mononuclear cells (“PBMCs”) were co-
cultured with gastric cancer cells derived from patient biopsies, givastomig was found to increase IL-2 production in a dose-dependent and CLDN18.2 
expression-dependent manner.

In transgenic mice expressing human 4-1BB that were engrafted with tumor cells expressing human CLDN18.2, givastomig treatment twice a week 
for three weeks suppressed tumor cell growth in six out of seven mice, delivering better efficacy than equimolar doses of single agent drugs targeting 
CLDN18.2 or 4-1BB alone or in combination. When these tumor-free mice were re-challenged with a second tumor implant a month after drug cessation, 
they remained protected from tumor implantation, indicating that givastomig produced a durable anti-tumor response. Immune cell analysis revealed a 
significant increase in CD45-positive and CD8-positive T cells that infiltrated the tumor tissue after givastomig treatment, but there were no changes in the 
periphery, suggesting that givastomig could turn a cold tumor into a hot tumor, and the effect was localized. The anti-tumor efficacy of givastomig was 
dose-dependent, with a minimal efficacious dose of 0.4 mg/kg.

or both, and with givastomig (4 mg/kg) twice a week for 3 weeks. All mAbs were dosed at the molar equivalent of 3 mg/kg.

Preclinical Pharmacodynamics and Safety 
The pharmacodynamic data and safety of givastomig in animal models and cell cultures were jointly announced by us and ABL Bio at the 2021 SITC 
annual meeting. Analysis of the data found: (1) potent anti-tumor activity was observed with the proliferation of immune cells in the tumor
microenvironment, as well as an increase in memory T cells in the peripheral blood, suggesting long-term immunity against the tumor; (2) givastomig was 
well tolerated in non-human primates and did not induce a systemic immune response or liver toxicity up to levels of 100mg/kg; and (3) activation of 
immune pathways by givastomig was demonstrated by a pro-inflammatory profile and increased gamma interferon-regulated gene expression in primary 
human CD8-positive T cells co-cultured with CLDN18.2 expressing cells. In the four-week good laboratory practice monkey toxicity study, givastomig 
was well tolerated with no major findings. There was no liver toxicity noted, nor was there evidence of systemic immune activation. There were mild 
stomach changes that were considered on-target but non-adverse and were reversible. The no observed adverse effect level (“NOAEL”) was determined to 
be 100 mg/kg.
Summary of Clinical Results
Phase 1 clinical trial of givastomig monotherapy in patients with advanced or metastatic solid tumors
The Phase 1 study consists of a dose escalation phase irrespective of CLDN18.2 expression status followed by dose expansion cohorts in CLDN18.2-
positive patients. The dose escalation part of the Phase 1 trial of givastomig monotherapy in patients with advanced solid tumors reached a dose of 15 
mg/kg without a dose limiting toxicity. By the end of 2022, eight dose cohorts had been completed, with 38 subjects dosed. Givastomig was well tolerated, 
most of the treatment-related adverse events were grade 1 or 2 and no dose limiting toxicity was reported. There was a dose-dependent increase of drug 
exposure and soluble 4-1BB in serum, suggestive of a favorable pharmacokinetic/pharmacodynamic profile with durable T cell activation. Partial responses 
and stable disease were observed across several dose levels in patients with gastric and esophageal cancer whose cancer had progressed after multiple lines 
of prior therapies, including PD-1 therapy. Efficacy signals were also observed in patients with low CLDN18.2 expression, highlighting its potential to treat 
CLDN18.2 low-expressing tumors where other CLDN18.2 targeted agents have shown a limited treatment effect. In October 2023 at the ESMO annual 
meeting, we presented updated topline Phase 1 data of givastomig that confirmed promising early efficacy signals, including signals in patients with low 
levels of CLDN18.2 tumor expression. Phase 1 dose escalation has reached the highest planned dose level. Most treatment-related adverse events were 
low-grade. In this trial, positive monotherapy efficacy results were observed, including in tumors with lower levels of CLDN18.2 expression.

Updated safety and efficacy data of givastomig in patients with CLDN18.2-positive advanced GEC
As of June 1, 2024, a total of 43 patients with CLDN18.2-positive GEC were enrolled and received givastomig at 5 mg/kg (n=7), 8 mg/kg (n=5), 12 
mg/kg (n=21) and 15 mg/kg (n=6) Q2W, and 18 mg/kg (n=4) Q3W. Of the 43 efficacy-evaluable patients, an ORR of 16.3% (7/43) was observed with a 
partial response (“PR”) in seven patients (one at 5 mg/kg, one at 8 mg/kg, four at 12 mg/kg and one at 18 mg/kg). Stable disease (“SD”) was reported in 14 
patients, with a disease control rate (“DCR”) of 48.8% (21/43). CLDN18.2 expression in responders ranged from 11% to 100%. Additionally, five 
responders had received prior treatment with PD-(L)1 inhibitors. A favorable safety profile, with mainly grade 1 or 2 TRAE and no observations of DLT or 
identification of a MTD supports further investigation of combination with other agents.

Clinical Development Plan
Based on the monotherapy data and early encouraging data from the ongoing first-line combination study with nivolumab and chemotherapy, we are 
focusing our resources on advancing givastomig as our lead asset. We are continuing to sponsor the Phase 1b dose escalation and dose expansion trials of 
givastomig in combination with standard of care, nivolumab and chemotherapy, in patients with CLDN18.2-positive (1+ intensity in ≥1% of cells) 
treatment naïve gastric, gastroesophageal junction and esophageal cancer. The dose escalation portion of the trials has been fully enrolled (n=17) with no 
MTD reached and no DLTs to date. We expect to present this dose escalation data in the second half of 2025. Based on the encouraging early data from the 
dose escalation trial, the previously planned dose expansion cohort (n=6-8) has been expanded to two dose cohorts, each evaluating 20 patients for a total 
of 40 patients. Patients will be enrolled irrespective of PD-L1 expression, but tumors must express CLDN18.2 at ≥1+ intensity in ≥1% of cells. On March 
7, 2025, we announced the completion of enrollment in the first expansion cohort as well as the first patient dosed in the second expansion cohort. We 
expect to share data from the dose expansion portion of the study in the first half of 2026. 
Competitive Landscape 
We believe givastomig, if approved, will primarily compete against other CLDN18.2 targeted molecules which include monoclonal antibodies, 
bispecific antibodies and antibody drug conjugates. VYLOY (zolbetuximab, marketed by Astellas) is the only approved therapy targeting CLDN18.2 to 
date. There are additional molecules undergoing clinical development by AstraZeneca (AZD0901 / CMG901), Transcenta (osemitamab), AskGene Pharma 
(ASKB589) and Innovent (IBI-343, IBI-389).

Uliledlimab (“TJD5”): A Highly Differentiated CD73 Antibody for Solid Tumors
Summary
Uliledlimab is a CD73 neutralizing antibody that targets a critical enzymatic step in the generation of adenosine. CD73 is a homodimeric enzyme 
widely expressed in multiple tumors and converts extracellular adenosine monophosphate (“AMP”) to adenosine, which contributes to an immuno-
suppressive tumor microenvironment. A key differentiating feature of uliledlimab, when compared to some of the other clinical-stage CD73 antibodies, is 
related to its novel epitope, which works through a unique intra-dimer binding mode, resulting in complete inhibition of the enzymatic activity and 
avoiding the aberrant pharmacological property known as the “hook effect.” In addition, uliledlimab has a non-competitive inhibitory effect that is not 
blunted by high levels of CD73 enzyme substrates, which may be observed in small-molecule competitive blockers. Preclinical studies have shown that 
uliledlimab can completely reverse the adenosine-mediated suppression of T cells in vitro. When combined with a PD-(L)1 antibody in vivo, uliledlimab 
exhibited a superior and synergistic inhibitory effect on tumor growth compared to PD-(L)1 monotherapy.
 
 
Figure: 
Differentiation of uliledlimab from other CD73 inhibitors. A key differentiating feature of the clinical development of uliledlimab is that we are 
testing the hypothesis that patients whose tumors express higher levels of CD-73 (and thereby have higher levels of adenosine) are more likely 
to respond to uliledlimab. In the U.S., we have completed the initial assessment of a Phase 1 clinical trial where uliledlimab was evaluated as a 
monotherapy lead-in and followed by combining it with atezolizumab (Tecentriq ) in patients with solid tumors. Topline results from this trial 
showed that uliledlimab was well-tolerated across all the dose cohorts evaluated. The data demonstrated a favorable linear pharmacokinetic and 
steep pharmacokinetic/pharmacodynamic relationship with complete receptor occupancy as expected based upon the normal dose-response 
property of uliledlimab without the hook effect. Furthermore, positive clinical efficacy signals from this trial were observed in non-small cell 
lung cancer and ovarian cancer patients with higher levels of CD73 and PD-L1 co-expression in the tumor, indicating a potential correlation 
between the clinical activity of uliledlimab and tumor CD73 expression as a potential predictive biomarker that warrants further investigation.
Supported by the results of the Phase 1 trial, Phase 2 trials are further evaluating the efficacy and safety of uliledlimab in combination with checkpoint 
inhibitors in Stage IV NSCLC and other select tumor types. The Phase 2 cohort data of uliledlimab in combination with toripalimab (TUOYI®), a 
programmed cell death protein (PD-1) inhibitor, in patients with Stage IV NSCLC were presented in June 2023 at the 2023 ASCO annual meeting. Results 
from an ongoing Phase 2 trial of uliledlimab in combination with toripalimab showed a favorable safety profile and an objective response rate of 63% 
(10/16) in patients whose tumors expressed higher levels of CD73 and had a PD-L1 tumor proportion score of >1%. In the overall population regardless of CD73 
and programmed cell death ligand (PD-L1) expression, the ORR was 31% (21/67).

Molecular Differentiation of Uliledlimab
Extracellular AMP can be generated from adenosine triphosphate (“ATP”), cyclic AMP, and nicotinamide adenine dinucleotide through separate 
biochemical pathways, all of which converge to CD73 as a rate-limiting enzyme to generate adenosine. Thus, the CD73 antibody may block adenosine 
generation more completely than other upstream targets in the adenosine pathway. The key advantages of uliledlimab when compared with other CD73 
antibodies or small molecule inhibitors can be summarized as follows: (1) uliledlimab exhibits a typical dose-response curve without the “hook effect” to 
achieve the complete inhibition of both soluble and surface-bound CD73; and (2) uliledlimab has a non-competitive inhibitory effect that is not blunted by 
high levels of CD73 enzyme substrates such as AMP, which may occur with small-molecule competitive blockers that target the AMP binding site on 
CD73. These pharmacological properties may translate into efficient target inhibition in tumors and superior anti-tumor activity, especially in an adenosine-
rich micro-environment.
Biochemically, uliledlimab displayed complete inhibition of soluble CD73 enzymatic activity (IC50 = 0.22 n M) without the “hook effect” in contrast 
to the comparator molecules, which at higher concentrations caused a paradoxical rebound of enzymatic activity presumably due to its inter-dimer binding 
mode. The recent structural data revealed by cryo-EM showed that uliledlimab binds to a unique epitope located at the C-terminus of CD73 dimer distinct 
from other CD73 antibodies, including oleclumab, all of which bind to the N-terminus of CD73. With this unique epitope, uliledlimab adopts a 
differentiated intra-dimer binding mode to prevent the conformational change of CD73 from inactive to the active form, resulting in the complete inhibition 
of CD73 enzymatic activity without causing a “hook effect.”
 
 
Figure: 
Inhibition of soluble CD73 enzymatic activity and the binding epitope of CD73 antibodies.
In preclinical studies, AMP inhibits interferon-gamma (IFN-γ) production by CD4 or CD8 T cells through adenosine generation, mimicking the 
suppressive tumor micro-environment where AMP is abundantly produced. However, this suppression can be reversed by uliledlimab in a concentration-
dependent manner. Moreover, in an experimental system where CD73 high human ovarian cell line SK-OV-3 and human T cells were co-cultured, the 
addition of uliledlimab restored T cell activity as measured by IFN-γ production in a concentration-dependent manner. In addition to the reversal of AMP-
mediated T cell suppression, uliledlimab treatment activates human B cells, as evidenced by the up-regulation of activation markers CD69 and CD83, as 
well as antigen presentation markers CD86 and HLA-DR. Compared with T cells, the effects of uliledlimab on B cells were adenosine independent.

Consistent with the in vitro results, in vivo monotherapy of uliledlimab dose-dependently inhibited in situ tumor-derived CD73 activity, leading to the 
anti-tumor effect in a mouse xenograft model bearing A375 melanoma cells, while such dose-dependency was not observed by oleclumab. 
 
 
Figure: 
Inhibitions of CD73 activity and tumor growth by uliledlimab and oleclumab.
To examine whether uliledlimab could enhance the anti-tumor activity of PD-1 or PD-L1 antibodies, we evaluated the therapeutic effects of 
uliledlimab in combination with a PD-1 antibody in the MC38 model using CD73 humanized mouse and a PD-L1 antibody in the A375 xenograft model, 
respectively. The combination treatments resulted in more potent inhibition of tumor growth than monotherapy with either the PD-(L)1 antibody or 
uliledlimab.

Summary of Clinical Results
Phase 2 clinical trial of uliledlimab in combination with PD-1 antibody (toripalimab) in advanced NSCLC
In June 2023, the clinical results of Phase 1b/2 study (NCT04322006) evaluating uliledlimab in combination with toripalimab (TUOYI®) in patients 
with NSCLC were presented at the 2023 ASCO annual meeting. The data are part of a dose expansion portion of a Phase 1b/2 trial evaluating the safety 
and efficacy of the combination therapy and investigating the potential correlation between tumor CD73 expression and clinical response for patients with 
advanced cancer.
As of April 14, 2023, 70 patients had been enrolled in the Phase 1b/2 cohort of uliledlimab and PD-1 combination therapy for patients with Stage IV 
NSCLC who were ineligible for or refused chemotherapy. Early results from an ongoing Phase 2 trial of uliledlimab in combination with toripalimab, a 
PD-1 inhibitor, showed a favorable safety profile and an objective response rate of 63% (10/16) in patients whose tumors expressed higher levels of CD73 
and had a PD-L1 tumor proportion score of >1%. In the overall population regardless of CD73 and programmed cell death ligand (PD-L1) expression, the 
ORR was 31% (21/67).
To confirm this data, a randomized study is underway by our collaborator, TJ Biopharma in China, which will test the combination of uliledlimab in 
combination with toripalimab vs. monotherapy toripalimab vs. monotherapy pembrolizumab, all in a CD73 high selected first-line, mNSCLC population. 
This study will directly support the hypothesis that CD73 expression will predict response to uliledlimab and provide insight into the magnitude of benefit 
when uliledlimab is added to a checkpoint inhibitor.
 
 
Figure: 
Phase 2 data of uliledlimab combined with toripalimab in treatment-naïve NSCLC patients.
Clinical Development Plan
Following the divestiture of our Greater China assets and business operations, we are pausing the development of uliledlimab to allow for further data 
from the ongoing randomized Phase 2 data in China, and to allocate resources to advance our lead clinical asset, givastomig. We will continue to monitor 
data from the ongoing China-only randomized study conducted by TJ Biopharma. Phase 2 progression free survival (“PFS”) data from this trial is expected 
to be presented by TJ Biopharma in 2026.
Competitive Landscape
We believe uliledlimab, if approved, would potentially compete with other CD73 antibodies in development. The most advanced CD73 antibody 
currently in clinical development is oleclumab (MEDI-9447) sponsored by AstraZeneca, which has initiated a Phase 3, double-blinded, placebo-controlled, 
randomized trial of durvalumab plus oleclumab in patients with locally advanced (Stage III), unresectable NSCLC who have not progressed following 
definitive, platinum-based concurrent chemoradiation therapy (PACIFIC 9). Arcus Biosciences also reported results in their Phase 1b/2 trial of 
quemliclustat, a small molecule CD73 inhibitor, in combination with zimberelimab plus chemotherapy in patients with treatment naïve pancreatic cancer. 
Drebuxelimab, also known as AK119 (from

Ragistomig (TJ-L14B): A PD-L1-Based Tumor-Dependent T-Cell Engager for Solid Tumors
Summary
Ragistomig, (also known as “ABL503” or “TJ-L14B”), is a bispecific antibody targeting both PD-L1 and 4-1BB that was developed in collaboration 
with ABL Bio. It was designed to improve the efficacy of anti-PD-(L)1 therapies while mitigating the potential toxicity associated with earlier 4-1BB-
directed therapies. Similar to givastomig, 4-1BB-stimulated T cell activity only occurs upon tumor cell binding by the anti-PD-L1 part of ragistomig. This 
localized T cell activation has the potential to exert strong anti-tumor activity while reducing systemic side effects such as liver toxicity. In a humanized 
mouse tumor model, a short course of ragistomig treatment displayed greater anti-tumor efficacy than anti-PD-L1 or anti-4-1BB antibodies alone or in 
combination and showed evidence of immunological memory response that resisted tumor re-challenge. Ragistomig is being jointly developed through a 
global partnership with ABL Bio, in which ABL Bio acts as the lead party and we share worldwide rights (50/50), excluding Greater China and South 
Korea, equally with ABL Bio.
Therapeutic Indications
New therapeutic options are urgently needed for cancers that are refractory to or relapse after PD-(L)1 treatment. The approach of ragistomig is to 
maximize T cell activity by simultaneously blocking the inhibitory pathways via PD-L1 binding and turning on co-stimulatory 4-1BB pathway.
Advantages of Ragistomig
We believe that based on publicly available information and preclinical studies, ragistomig has the potential to be a highly differentiated PD-L1 and 4-
1BB bispecific antibody. In terms of format, some of the leading compounds are monovalent heterodimers which may affect the potency of each arm and 
increase the complexity of chemistry, manufacturing and controls. In addition, as detailed earlier, the anti-4-1BB moiety of ragistomig binds to a novel 
epitope that only triggers 4-1BB signaling upon tumor binding leading to a reduced cytokine release and hepatic and systemic immunotoxicity without 
compromising anti-tumor activity. Ragistomig is also more specific than certain competitor molecules in terms of 4-1BB binding relative to other TNFR 
families of co-stimulatory molecules. If proven in clinical trials, these potential advantages could differentiate ragistomig from other competing 
compounds.

Summary of Preclinical Results
The ability of ragistomig to ligate 4-1BB and activate downstream signaling was tested in a co-culture of PD-L1-positive target cells with T cells as 
effectors (shown below). The results show that the level of NF-kB reporter activity elicited by ragistomig correlated with the level of PD-L1 expression on 
the target cells. In contrast, urelumab induced NF-kB reporter activity regardless of target cell PD-L1 expression. Importantly, ragistomig promoted the 
proliferation of CD8-positive tumor-infiltrating lymphocytes obtained from human tumor samples to a similar extent as urelumab, while the parental anti-
PD-L1 and anti-4-1BB antibodies, either alone or in combination, had no effect, confirming a strict PD-L1-dependence on T cell stimulation by ragistomig.

In mice grafted with tumor cells expressing human PD-L1, ragistomig treatment every three days for four cycles suppressed tumor cell growth in a 
dose-dependent manner, delivering far better efficacy than equimolar doses of single agents alone or in combination. When the treated tumor-free mice 
were re-challenged with a second tumor graft after drug cessation, they remained resistant, indicating that ragistomig produced a durable anti-tumor 
response.

expressing human PD-L1. Mice were treated with the indicated antibodies every three days for four cycles. Tumor-free animals were re-
challenged with a second dose of the tumor on day 40 with treatment-naïve animals as a control.
Preclinical Safety
In contrast to certain competitor PD-L1 x 4-1BB bispecific antibodies, ragistomig did not induce cytokine release (including IL-6 and TNF-α) up to 
0.83 mg/ml, which corresponded to a human equivalent dose of 15 mg/kg. Animal pharmacokinetic and toxicity studies have also been completed. Results 
of these studies indicate that the NOAEL was 15 mg/kg/dose. This dose was also considered the highest non-severely toxic dose. A starting dose of 0.7 mg 
was proposed for the first-in-human study. There is a greater than 3000-fold safety margin between the proposed first-in-human dose and the nonclinical 
safety assessment studies including in vitro cytokine release assays and good laboratory practice toxicology studies. 
Summary of Clinical Results
In June 2024, our development partner, ABL Bio, presented promising objective responses in patients with various advanced solid tumors that are 
refractory or have relapsed after PD-(L)1 inhibitors from the Phase 1 dose escalation study at ASCO 2024. Of the 53 enrolled patients, 44 were efficacy 
evaluable patients with advanced or relapsed/refractory solid tumor. 64.2% (34/53) of enrolled patients had at least three prior lines of therapies. Top-line 
Phase 1 dose escalation and dose expansion results demonstrated an ORR of 26.9% (7/26), including six partial responses (“PRs”) and one complete 
response (“CR”), and a clinical benefit rate (“CBR”) of 69.2% (18/26) at doses of 3 mg/kg and 5 mg/kg. 71.4% of responders received prior treatment with 
anti-PD-(L)1 inhibitors.
Clinical Development Plan
Our partner ABL Bio is conducting a Phase 1b study to increase the therapeutic index by decreasing the dosing level and/or frequency, and to identify 
the appropriate tumor types for further development. 
Competitive Landscape
We believe ragistomig, if approved, will primarily compete against other PD-L1 x 4-1BB bispecific antibodies and secondarily against therapeutic 
options designed for cancers that are refractory to or relapse after PD-(L)1 treatment. There are currently no approved or marketed therapies utilizing the 
PD-L1 x 4-1BB pathway. However, there are competing molecules within the class currently undergoing clinical development. Genmab is also currently 
developing PD-L1 x 4-1BB bispecific antibodies.

Licensing and Collaboration Arrangements
A. In-Licensing Arrangements
Licensing Agreement with Ferring (Olamkicept)
In November 2016, we entered into a license and sublicense agreement with Ferring International Center SA (“Ferring”), with respect to (i) FE301, an 
interleukin-6 inhibitor, and (ii) all pharmaceutical formulations in finished packaged form containing FE301 covered by certain patents or patent 
applications. Under this agreement, Ferring granted to us an exclusive, sublicensable license (excluding any non-exclusive license that Ferring granted to 
Conaris Research Institute AG under a licensing agreement entered into in November 2008) under certain Ferring intellectual property to research, develop, 
make, have made, import, use, sell and offer to sell FE301 (and the licensed products containing FE301) in mainland China, Hong Kong, Macau, Taiwan 
and South Korea. We also have an option to receive an exclusive, sublicensable license under certain Ferring intellectual property to research, develop, 
make, have made, import, use, sell and offer to sell FE301 (and the licensed products containing FE301) in countries in North America, the European 
Union and Japan that are mutually agreed upon by the parties.
We are required to use commercially reasonable efforts to obtain approval of FE301 and to promote, market, distribute and sell it in mainland China, 
Hong Kong, Macau, Taiwan and South Korea. Such activities are to be at our own cost and expense.
Under this agreement, we paid to Ferring an upfront license fee of $2.0 million. We also agreed to make milestone payments to Ferring, in the 
aggregate amount of $14.5 million, conditioned on the achievement of certain development milestones in the licensed territory, including completion of 
Phase 1b and Phase 2a clinical trials and the submission and approval of the new drug application. Further, if we exercise our option to receive a license in 
any of the mutually agreed upon countries in North America, the European Union and Japan, we are required to pay to Ferring an additional $3.0 million as 
an upfront license fee (upon the exercise of the option), and milestone fees up to the aggregate amount of $30.0 million, conditioned upon the licensed 
product achieving certain development milestones in certain countries in the option territory.
In addition, we agreed to pay Ferring tiered royalties ranging from the mid-single-digit to high-single-digit percentages of annual net sales for 
countries in mainland China, Hong Kong, Macau, Taiwan and South Korea, and from the high-single-digits to 10% of annual net sales for the mutually 
agreed upon countries in North America, the European Union and Japan. To date, we have not paid any royalties to Ferring.
The royalty term commences with the first commercial sale of the licensed product in the relevant country and ends upon the later of (i) 15 years from 
the date of launch, and (ii) the expiry of the last to expire patent of Ferring that includes a valid claim covering the development, making, using or selling of 
the licensed compound or licensed product in the licensed territory and/or option territory. Unless terminated earlier in accordance with the terms thereof, 
this agreement will remain in effect until the later of the expiry of the royalty term, and the first date on which we are not conducting any necessary and 
outstanding clinical trial with respect to the licensed product or seeking to obtain any necessary and pending regulatory approval for the licensed product, if 
applicable. This agreement may be terminated by either party for the other party’s uncured material breach, bankruptcy or insolvency. In addition, in the 
event that the original licensor terminates its license to Ferring governing any of the intellectual property sublicensed to us under this agreement, Ferring 
has the right to terminate this agreement with respect to such sublicenses in which case both parties will discuss in good faith how to resolve and mitigate 
to mutual satisfaction. To the extent that Ferring terminates for our material breach, bankruptcy or insolvency, among other things, all licenses and rights 
granted by Ferring to us will automatically terminate and the licenses and rights we granted to Ferring will survive and automatically become irrevocable 
with the right to sublicense.
During the term of the licensing agreement, if we develop or acquire any improvement, modification, enhancement or addition to the licensed product, 
we will own and retain all rights, title and interest therein, and grant to Ferring a non-exclusive, fully paid, royalty-free, worldwide license thereto.
In September 2020, we entered into a sublicense agreement with TJBio Hangzhou, under which we sublicensed to TJBio Hangzhou an exclusive, 
sublicensable license to develop, manufacture and commercialize olamkicept in mainland China, Hong Kong, Macau, Taiwan and South Korea. In 
December 2021, we entered into a supplementary sublicensing agreement with TJBio Hangzhou, pursuant to which TJBio Hangzhou, as a sub-licensee of 
olamkicept (TJ301) in Greater China and Korea, agreed to pay $3.0 million to us for the completion of olamkicept (TJ301) Phase 2a study report. After 
receiving the milestone payment of $3.0 million from TJBio Hangzhou, we made the payment of $3.0 million to Ferring during 2022.
In May 2022, we entered into an amended and restated license and sublicense agreement and a cell line and manufacturing collaboration agreement 
with Ferring, under which we granted to Ferring an exclusive, perpetual and transferable sublicense, with the right to grant further sublicenses to 
sublicensees, under all of the intellectual properties licensed to us by our business partner, to research, 

 
72
Table of Contents
develop, make, import, use and sell olamkicept as expressed by or produced by cell lines created by our business partner and its affiliates in any human 
indications in the territories other than Greater China and Korea. We also granted to Ferring an exclusive, perpetual and royalty-free license, with right of 
sublicense to sublicensees, under the intellectual property owned or controlled by our company which relates to cell lines created by our business partner 
and its affiliates, for the research, development, making, using or selling of olamkicept, including prespecified patents and know-how and improvements 
thereto. In December 2022, we delivered the data package defined in the first milestone of the amended and restated license and sublicense agreement with 
Ferring and recognized $5.5 million of revenue. We subsequently paid to TJBio Hangzhou $2.75 million and reduced the amount of revenue recognized by 
such amount. To our knowledge, TJBio Hangzhou has ceased the development of olamkicept. 
B. Collaboration Arrangements
In July 2018, we entered into a collaboration agreement with ABL Bio, which has been subsequently amended, whereby both parties agreed to 
collaborate to develop two bispecific antibodies by using ABL Bio’s proprietary BsAb technology and commercialize them in their respective territories, 
which, collectively, include Greater China and South Korea, and other territories throughout the rest of the world if both parties agree to do so in such other 
territories during the performance of the agreement. This agreement may be terminated by either party for the other party’s uncured material breach or in 
the event that the other party challenges its patents. Also, if a party encounters insurmountable technical difficulties and risks, which cannot be resolved by 
such party within a certain period thereafter despite all reasonable efforts, such party will have the right to terminate this agreement and will no longer have 
the right to develop the licensed product. Following the divestiture of our Greater China assets and business operations and as of the date of this annual 
report, our rights in the collaboration agreement are limited to a 50/50 split for worldwide rights excluding Greater China and South Korea.
In November 2018, we entered into collaboration agreements with Tracon, whereby we and Tracon agreed to (i) co-develop our proprietary CD73 
antibody, TJD5, and (ii) collaborate to co-develop up to five bispecific antibodies. Both agreements may be terminated by either party for the other party’s 
uncured material breach, bankruptcy or insolvency or for other reasons. In April 2020, Tracon issued a notice of disputes with respect to these agreements. 
In February 2021, we sent Tracon a notice to terminate the agreement we entered into with Tracon to co-develop TJD5, which would result in a 
prespecified termination fee of $9.0 million owing to Tracon. The disputes were presented to a binding arbitration proceeding under the Rules of 
Arbitration of the International Chamber of Commerce before an arbitration tribunal. On April 25, 2023, the arbitration award determined that the 
agreement in relation to TJD5 has been terminated for a pre-agreed termination fee of $9.0 million plus interest payable pursuant to the original agreement, 
and therefore Tracon has no rights to share any future economics with us. In July 2023, the pre-agreed termination fee in relation to TJD5 and an agreed-
upon portion of Tracon’s legal fees and costs to Tracon were paid by I-Mab. The financial impacts of the transaction were allocated to discontinued 
operations for the periods presented. 
In June 2024, we entered into a clinical trial collaboration and supply agreement with Bristol-Myers Squibb Company (“BMS”) to evaluate our novel 
bispecific antibody, givastomig, targeting Claudin18.2 x 4-1BB in clinical trials, in combination with BMS’s anti-PD-1 monoclonal antibody product 
known as OPDIVO® (nivolumab). Under the terms of the agreement, we will be responsible for sponsoring and conducting, at our own cost, a multi-
national Phase 1 trial of givastomig in combination with nivolumab. BMS will manufacture and supply a sufficient amount of nivolumab to us solely for 
the conduct of the combination therapy at no charge to us. BMS grants to us a non-exclusive, non-transferable, fully-paid-up, royalty-free license 
worldwide, except for certain specified territory, to use nivolumab in research and development solely to the extent necessary to conduct the combination 
therapy, seek regulatory approval for, and upon such regulatory approval, market and promote givastomig for use in the combination therapy with 
nivolumab. We grant to BMS a non-exclusive, non-transferable, fully-paid-up, royalty-free license worldwide, except for certain specified territory, to seek
regulatory approval for, and upon such regulatory approval, market and promote nivolumab in the combination therapy with givastomig.
Competition
Our industry is highly competitive and subject to rapid and significant change. While we believe that our management’s research and development 
experience provides us with competitive advantages, we face competition from global biopharmaceutical companies, including specialty pharmaceutical 
companies, generic drug companies, biologics drug companies, academic institutions, government agencies and research institutions.

 
73
Table of Contents
For our Global portfolio of drug candidates, we expect to face competition from a broad range of global and local pharmaceutical companies. Many of 
our competitors have significantly greater financial, technical and human resources than we have, and mergers and acquisitions in the biopharmaceutical 
industry may result in even more resources being concentrated among a smaller number of our competitors. Our commercial opportunity could be reduced 
or eliminated if our competitors develop or market products or other novel therapies that are more effective, safer or less costly than our current or future 
drug candidates or obtain regulatory approval for their products more rapidly than we may obtain approval for our drug candidates.
Intellectual Property
Our success will depend significantly on our ability to obtain and maintain patent and other proprietary protection for our drug candidates and other 
commercially important products, technologies, inventions and know-how, as well as on our ability to defend and enforce our patents including any patent 
that we have or may issue from our patent applications, preserve the confidentiality of our trade secrets and operate without infringing the valid and 
enforceable patents and proprietary rights of other parties.
As of the date of this annual report, our owned patent portfolio consists of (i) 63 issued patents, including four issued in the United States, two issued 
in Korea and 57 issued in other jurisdictions; and (ii) 60 pending patent applications, including two Patent Cooperation Treaty (PCT) patent applications, 
five U.S. patent applications, and 53 patent applications in other jurisdictions. Our owned patents and patent applications primarily relate to the drug 
candidates in our Global portfolio.
 
Givastomig 
As of the date of this annual report, we co-owned three PCT patent applications with ABL Bio, two of which have entered 
national phases including in Europe, the United States, and additional jurisdictions. We expect that any patent that may 
issue under these applications will expire between 2040 and 2043, before taking into account any extension that may be 
obtained through patent term extension or adjustment, or term reduction due to filing of terminal disclaimers.
 
 
Uliledlimab 
As of the date of this annual report, we owned three PCT patent applications, all of which have entered national phases 
including in Europe, the United States, and additional jurisdictions. We expect that any patent that may issue under these 
applications will expire between 2038 and 2043, before taking into account any extension that may be obtained through 
patent term extension or adjustment, or term reduction due to filing of terminal disclaimers.
 
 
Ragistomig 
As of the date of this annual report, we co-owned two PCT patent applications with ABL Bio, one of which has entered 
national phases including Europe, the United States, and additional jurisdictions. We expect that any patent that may issue 
under these applications will expire between 2039 and 2044, before taking into account any extension that may be obtained 
through patent term extension or adjustment, or term reduction due to filing of terminal disclaimers.
 
The term of a patent depends upon the laws of the country in which it is issued. In most jurisdictions, the patent term of a utility patent is 20 years 
from the earliest filing date of a non-provisional patent application; the patent term of a design patent is 15 years from the date of patent grant; and utility 
models are effective for ten years from the date of application.
In addition to patents, we rely upon unpatented trade secrets and know-how and continuing technological innovation to develop and maintain our 
competitive position. However, trade secrets and know-how can be difficult to protect. We seek to protect our proprietary information, in part, by executing 
confidentiality agreements with our partners, collaborators, scientific advisors, employees, consultants and other third parties, and invention assignment 
agreements with our consultants and employees. We have also executed agreements requiring assignment of inventions with selected scientific advisors 
and collaborators. The confidentiality agreements we enter into are designed to protect our proprietary information and the agreements or clauses requiring 
assignment of inventions to us are designed to grant us ownership of technologies that are developed through our relationship with the respective 
counterparty. We cannot guarantee that we have entered into such agreements with each party that may have or have had access to our trade secrets or 
proprietary technology and processes or that these agreements will afford us adequate protection of our intellectual property and proprietary information 
rights. If any of the partners, collaborators, scientific advisors, employees and consultants who are parties to these agreements breaches or violates the 
terms of any of these agreements or otherwise discloses our proprietary information, we may not have adequate remedies for any such breach or violation, 
and we could lose our trade secrets as a result.
Additionally, as of the date of this annual report, we had (i) three trademark registrations in Hong Kong, 59 trademark registrations in the PRC, six 
trademark registrations in the United States, two trademark registrations in France, two trademark registrations in the European Union, one trademark 
registration in South Korea, one trademark registration in the United Kingdom, one International

trademark registration, and four trademark applications pending in the PRC; and (ii) seven domain names in Hong Kong, one domain name in the Cayman 
Islands, and one domain name in the United States.
For more information on these and other risks related to intellectual property, see “Item 3. Key Information—D. Risk Factors—Risks Related to Our 
Intellectual Property.” 
Environmental, Health and Safety Matters
In August 2021, we established an environmental, social and governance (ESG) committee. The committee consists of one independent director and 
one director, Mr. Chun Kwok Alan Au and Dr. Xi-Yong (Sean) Fu, respectively. Mr. Chun Kwok Alan Au chairs the committee. As the oversight body for 
our ESG practices, the committee is responsible for supervising our ESG strategies, policies, long-term sustainability objectives and risks.
With the current state of business operations, we have no significant environmental impact due to no large-scale manufacturing operations. We abide 
by local laws and regulations on environmental protection and only discharge a small amount of wastewater after proper treatment. We also provided 
employee training, set up standard operation procedures and contingency plans for potential accidents of environmental, health and safety.
At present, energy and resources consumed in our daily operations are mainly municipal electricity and domestic water. We assigned a dedicated team 
to regularly inspect and maintain the equipment, measure total consumption, and train employees on water and energy saving measures.
Safety and health are the foundation of our operational activities. We have created a comprehensive internal safety management system to ensure 
compliance, strengthen risk assessment and management. We offered standard operating procedures to ensure employees are aware of any potential 
hazards, including providing emergency training, treatment facilities, and personal protection equipment to all employees.
Regulation
We are subject to a variety of U.S. and PRC laws, rules and regulations affecting many aspects of our business. This section summarizes the principal 
laws and regulations in the United States and China that we believe are relevant to our business and operations.
PRC Regulation
We are subject to a variety of PRC laws, rules and regulations affecting many aspects of our business. This section summarizes the principal PRC 
laws, rules and regulations that we believe are relevant to our business and operations.
Regulations on Company Establishment and Foreign Investment
Company Law
The establishment, operation and management of companies in China is governed by the PRC Company Law, the latest amended edition of which 
came into effect on July 1, 2024. In light of the PRC Company Law, companies established in the PRC are either in the form of a limited liability company 
or a joint stock company. The PRC Company Law applies to both PRC domestic companies and foreign-invested companies, unless otherwise provided in 
the foreign investment laws and regulations.
Foreign Investment Law
On March 15, 2019, the National People’s Congress approved the PRC Foreign Investment Law, which became effective on January 1, 2020. The 
Foreign Investment Law establishes the basic framework for the access to, and the promotion, protection and administration of foreign investments in view 
of investment protection and fair competition. According to the Foreign Investment Law, “foreign investment” refer to investment activities directly or 
indirectly conducted by one or more natural persons, business entities, or other organizations of a foreign country (collectively referred to as “foreign 
investor”) within China, and “investment activities” include the following activities: (i) a foreign investor, individually or together with other investors, 
establishes a foreign-invested enterprise within China; (ii) a foreign investor acquires stock shares, equity shares, shares in assets, or other similar rights 
and interests of an enterprise within China; (iii) a foreign investor, individually or together with other investors, invests in a new construction project within 
China; and (iv) investments in other means as provided by the laws, administrative regulations or the State Council.

Table of Contents
Regulations Relating to Foreign Investment
On December 26, 2019, the State Council promulgated the Implementation Rules to the Foreign Investment Law, which became effective on January 
1, 2020. The implementation rules further clarified that the state encourages and promotes foreign investment, protects the lawful rights and interests of 
foreign investors, regulates foreign investment administration, continues to optimize foreign investment environment, and advances a higher-level opening.
Furthermore, PRC-based investments by foreign investors are currently regulated by the Special Management Measures (Negative List) for the Access 
of Foreign Investment (2024) issued on September 6, 2024 and effective from November 1, 2024, and the Catalogue of Industries for Encouraging Foreign 
Investment (2022 Version) issued on October 26, 2022 and effective from January 21, 2023. According to the aforesaid catalogue and management 
measures, foreign-invested industries fall into four categories, namely, “encouraged”, “permitted”, “restricted” and “prohibited” and certain ownership 
requirements, requirements for senior executives and other special management measures should apply to foreign investors with regard to the access of 
foreign investments in certain categories.
On December 30, 2019, the Ministry of Commerce and the State Administration for Market Regulation jointly promulgated Measures for Information 
Reporting on Foreign Investment, which became effective on January 1, 2020. Pursuant to the Measures for Information Reporting on Foreign Investment, 
where a foreign investor carries out investment activities in China directly or indirectly, the foreign investor or the foreign-invested enterprise should 
submit the investment information to the competent commerce department.
M&A Rules
According to the Provisions on the Merger or Acquisition of Domestic Enterprises by Foreign Investors jointly issued by the Ministry of Commerce, 
the State Assets Supervision and Administration Commission of the State Council, the State Administration of Taxation, the State Administration for 
Industry and Commerce (now known as the State Administration for Market Regulation), the China Securities Regulatory Commission and SAFE on 
August 8, 2006 and amended by the Ministry of Commerce on June 22, 2009, among other things, (i) the purchase of an equity interest or subscription to 
the increase in the registered capital of non-foreign-invested enterprises, (ii) the establishment of foreign-invested enterprises to purchase and operate the 
assets of non-foreign-invested enterprises, or (iii) the purchase of the assets of non-foreign-invested enterprises and the use of such assets to establish 
foreign-invested enterprises to operate such assets, in each case, by foreign investors is subject to the Provisions on the Merger or Acquisition of Domestic 
Enterprises by Foreign Investors. Particularly, application should be made for examination and approval of the acquisition of any company in China 
affiliating to a domestic company, enterprise or natural person, which is made in the name of an oversea company established or controlled by such 
domestic company, enterprise or natural person.
PRC Drug Regulation
The Drug Administration Law of the PRC promulgated by the Standing Committee of the National People’s Congress on September 20, 1984 and 
effective from July 1, 1985 and amended on February 28, 2001, December 28, 2013, April 24, 2015 and August 26, 2019, respectively, and the 
Implementing Measures of the Drug Administration Law promulgated by the State Council on August 4, 2002 and effective from September 15, 2002 and 
amended on February 6, 2016, March 2, 2019 and December 6, 2024, respectively, have jointly established the legal framework for the administration of 
pharmaceutical products in China, including the research, development and manufacturing of new drugs. The Drug Administration Law applies to entities 
and individuals engaged in the development, production, trade, application, supervision and administration of pharmaceutical products, which regulates and 
provides for a framework for the administration of pharmaceutical manufacturers, pharmaceutical trading companies and medicinal preparations of medical 
institutions, and the development, research, manufacturing, distribution, packaging, pricing and advertisements of pharmaceutical products. The 
Implementing Measures of the Drug Administration Law, on the other hand, provides detailed implementation regulations for the Drug Administration 
Law.
The amendment to the Drug Administration Law in 2019 brought a series of changes to the drug supervision and administration system, including the 
clarification of the drug marketing authorization holder system, pursuant to which the marketing authorization holder should assume responsibilities for 
non-clinical studies, clinical trials, manufacturing and marketing, post-marketing studies, monitoring, reporting and handling of adverse reactions of the 
drug. The amendment also stipulates that the State supports the innovation of drugs with clinical value and specific or special effects on human diseases, 
encourages the development of drugs with new therapeutic mechanisms and have multi-targeted, systematic regulatory and intervention functions on 
human body and promotes the technological advancement of drugs.

Regulatory Authorities
Pharmaceutical products and medical devices and equipment in China are monitored and supervised on a national scale by the National Medical 
Products Administration (the “NMPA”), while the local provincial medical products administrative authorities are responsible for the supervision and 
administration of drugs within their respective administrative regions.
The NMPA is the chief drug regulatory agency and the NMPA regulates almost all of the key stages of the life cycle of pharmaceutical products, 
including non-clinical studies, clinical trials, marketing approvals, manufacturing, advertising and promotion, distribution, and pharmacovigilance (i.e., 
post-marketing safety reporting obligations). The Center for Drug Evaluation, which remains under the NMPA, conducts the technical evaluation of each 
drug and biologic application for safety and effectiveness.
The National Health Commission is China’s chief healthcare regulator. It is primarily responsible for overseeing the operation of medical institutions, 
which also serve as clinical trial sites, and regulating the licensure of hospitals and medical personnel. The National Health Commission plays a significant 
role in drug reimbursement. Furthermore, the National Health Commission and its local counterparts at or below provincial-level local governments also 
oversee and organize public medical institutions’ centralized bidding and procurement process for pharmaceutical products, which is the chief means 
through which public hospitals and their internal pharmacies acquire drugs.
Manufacturing and Distribution
According to the Drug Administration Law, all facilities that manufacture drugs in China must receive a drug manufacturing license from the local 
drug regulatory authority. Each drug manufacturing license issued to a pharmaceutical manufacturing enterprise is effective for a period of five years.
Similarly, for sales, importation, shipping and storage businesses, a company must obtain a distribution license from the local drug regulatory 
authority, subject to renewal every five years.
China has implemented a “Two-Invoice System” to control the distribution of prescription drugs. The “Two-Invoice System” generally requires that 
no more than two invoices be issued throughout the distribution chain: one from the manufacturer to a distributor and another from the distributor to the 
end-user hospital. This excludes the sale of products invoiced from the manufacturer to its wholly-owned or controlled distributors, or for imported drugs, 
to its exclusive distributor, or from a distributor to its wholly-owned or controlled subsidiary (or between its wholly-owned or controlled subsidiaries). 
However, the system still significantly limits the options for companies to use multiple distributors to reach a larger geographic area in China. Compliance 
with the Two-Invoice System is a prerequisite for pharmaceutical companies to participate in the procurement processes of public hospitals, which 
currently provide most of China’s healthcare services. Manufacturers and distributors that fail to implement the Two-Invoice System may lose their 
qualifications to participate in the bidding process. Non-compliant manufacturers may also be blacklisted from engaging in drug sales to public hospitals in 
a locality.
The Two-Invoice System was first implemented in 11 provinces involved in pilot comprehensive medical reforms, and the program has been 
expanded to nearly all provinces, each with its own individual rules for the program.
New Drug Application
Pursuant to the Administrative Measures for Drug Registration, upon completion of research and other preparation work, the applicant may apply to 
the NMPA for approval of a new drug application. The NMPA will then determine whether to approve the application according to the comprehensive 
evaluation opinion issued by the Center for Drug Evaluation of the NMPA.
At the stage of new drug application, depending on the characteristics of the drug and the corresponding conditions, applicants may apply for adoption 
of special procedures, including the Priority Review Procedure and the Special Review Procedure. Such procedures may be applied for innovative drugs for 
severe infectious diseases or rare diseases, breakthrough drugs and other eligible drugs stipulated in the Administrative Measures for Drug Registration. 
Extra policy support, including less review period, may be given to applicants in such special procedures.
Marketing Authorization Holder System
Pursuant to the Drug Administration Law, under the drug marketing authorization holder mechanism, an enterprise or a research and development 
institution, which has obtained a drug registration certificate is eligible to be a drug marketing authorization holder and the drug marketing authorization 
holder should be responsible for nonclinical laboratory studies, clinical trials, production and distribution, post-market studies, and the monitoring, 
reporting, and handling of adverse reactions in connection with pharmaceuticals 

 
77
Table of Contents
in accordance with the provisions of the Drug Administration Law. The drug marketing authorization holder may engage contract manufacturers for 
manufacturing, provided that the contract manufacturers are licensed and may engage pharmaceutical distribution enterprises with drug distribution license 
for sales, importation, shipping and storage businesses. Upon the approval of the medical products administrative department under the State Council, a 
drug marketing authorization holder may transfer the drug marketing license and the transferee should have the capability of quality management, risk
prevention and control, and liability compensation to ensure the safety, effectiveness and quality controllability of drugs, and fulfill the obligations of the 
drug marketing license holder.
Intellectual Property Rights
China became a member of the World Trade Organization and a party to the Agreement on Trade-Related Aspects of Intellectual Property Rights on 
December 11, 2001. China has also entered into several international conventions on intellectual property rights, including the Paris Convention for the 
Protection of Industrial Property, the Madrid Agreement Concerning the International Registration of Marks, and the Patent Cooperation Treaty.
Patents
Pursuant to the PRC Patent Law promulgated by the Standing Committee of the National People’s Congress on March 12, 1984 and amended on 
September 4, 1992, August 25, 2000, December 27, 2008 and October 17, 2020, respectively, and the latest revision thereto became effective from June 1, 
2021, and the Implementation Rules of the Patent Law of the PRC promulgated by the State Council on June 15, 2001 and amended on December 28, 2002 
and January 9, 2010 and December 11, 2023, respectively and the latest revision thereto became effective from January 20, 2024, patents in China fall into 
three categories: invention, utility model and design. An invention patent is granted to a new technical solution proposed in respect of a product or method 
or an improvement of a product or method. A utility model is granted to a new technical solution that is practicable for application and proposed in respect 
of the shape, structure or a combination of both of a product. A design patent is granted to the new design of a certain product in shape, pattern or a 
combination of both and in color, shape and pattern combinations aesthetically suitable for industrial application. Under the PRC Patent Law, the term of 
patent protection starts from the date of application. Patents relating to invention are effective for twenty years, patents relating to utility models are 
effective for ten years, and patents relating to designs are effective for fifteen years, from the date of application. The PRC Patent Law adopts the principle 
of “first-to-file” system, which provides that if there is more than one person files a patent application for the same invention, a patent will be granted to the 
person who files the application first.
In China, a patent must have novelty, creativity and practical applicability. Under the PRC Patent Law, novelty means that before a patent application 
is filed, no identical invention or utility model has been publicly disclosed in any publication in China or overseas or has been publicly used or made 
known to the public by any other means, whether in or outside of China, nor has any other person filed with the patent authority an application that 
describes an identical invention or utility model and is recorded in patent application documents or patent documents published after the filing date. 
Creativity means that, compared with existing technology, an invention has prominent substantial features and represents notable progress, and a utility 
model has substantial features and represents any progress. Practical applicability means an invention or utility model can be manufactured or used and 
may produce positive results. Patents in China are filed with the China National Intellectual Property Administration (“CNIPA”). Normally, the CNIPA 
publishes an application for an invention patent within 18 months after the filing date, which may be shortened at the request of applicant. The applicant 
must apply to the CNIPA for a substantive examination within three years from the date of application.
Article 19 of the PRC Patent Law provides that, for an invention or utility model completed in China, any applicant (not just Chinese companies and 
individuals), before filing a patent application outside of China, must first submit it to the CNIPA for a confidential examination. Any failure to comply 
with this requirement would result in the denial of any Chinese patent for the invention or utility model.
Meanwhile, the Patent Law implements a “compensation for patent term” measure. In the event that an invention patent is granted after the fourth 
anniversary of the date of application and the third anniversary of the date of the request for substantive examination, the Patent Administration Department 
of the State Council should, at the request of the patentee, provide the compensation for patent term for the unreasonable delay in the process of granting 
the patent, except for the unreasonable delay caused by the applicant. In particular, in order to compensate the time taken for the review and approval of 
new drugs, if the new drug-related invention patents are approved for marketing in China, the Patent Administration Department of the State Council 
should provide the compensation for patent term to the patentee, for the duration of patent rights at the request of the patentee. The compensation for patent 
term should not exceed five years, and the total effective patent right period after the new drug is approved for marketing should not exceed fourteen years.

Patent Enforcement
Unauthorized use of patents without consent from owners of patents, forgery of the patents belonging to other persons, or engagement in other patent 
infringement acts, will subject the infringers to infringement liability. Serious offenses such as forgery of patents may be subject to criminal penalties.
When a dispute arises out of infringement of the patent owner’s patent right, Chinese law requires that the parties first attempt to settle the dispute 
through mutual consultation. However, if the dispute cannot be settled through mutual consultation, the patent owner, or an interested party who believes 
the patent is being infringed, may either file a civil legal suit or file an administrative complaint with the patent administration authority. A Chinese court 
may issue a preliminary injunction upon the patent owner’s or an interested party’s request before instituting any legal proceedings or during the 
proceedings. Damages for infringement are calculated as the loss suffered by the patent holder arising from the infringement, and if the loss suffered by the 
patent holder arising from the infringement cannot be determined, the damages for infringement should be calculated as the benefit gained by the infringer 
from the infringement. If it is difficult to ascertain damages in this manner, damages may be determined by using a reasonable multiple of the license fee 
under a contractual license. Statutory damages may be awarded in the circumstances where the damages cannot be determined by the above-mentioned 
calculation standards. The damage calculation methods should be applied in the aforementioned order. Generally, the patent owner has the burden of 
proving that the patent is being infringed. However, if the owner of an invention patent for manufacturing process of a new product alleges infringement of 
its patent, the alleged infringer has the burden of proof.
Medical Patent Compulsory License
According to the PRC Patent Law, for the purpose of public health, the CNIPA may grant a compulsory license for manufacturing patented drugs and 
exporting them to countries or regions covered under international treaties to which the PRC has acceded.
Trade Secrets
Pursuant to the PRC Anti-Unfair Competition Law promulgated by the Standing Committee of the National People’s Congress on September 2, 1993 
and amended on November 4, 2017 and April 23, 2019, respectively, the term “trade secrets” refers to technical and business information that is unknown 
to the public, has utility, may create business interests or profits for its legal owners or holders, and is maintained as a secret by its legal owners or holders. 
Under the PRC Anti-Unfair Competition Law, business persons are prohibited from infringing others’ trade secrets by (i) obtaining the trade secrets from 
the legal owners or holders by any unfair methods, such as theft, bribery, fraud, coercion, electronic intrusion, or any other illicit means; (ii) disclosing, 
using or permitting others to use the trade secrets obtained illegally under item (i), (iii) disclosing, using or permitting others to use the trade secrets, in 
violation of any contractual agreements or any requirements of the legal owners or holders to keep such trade secrets in confidence, or (iv) instigating, 
inducing or assisting others to disclose, use or permit others to use the trade secrets, in violation of any contractual agreements or any requirement of the 
legal owners or holders to keep such trade secret in confidence. If a third party knows or should have known of the above-mentioned illegal conduct but 
nevertheless obtains, uses or discloses trade secrets of others, the third party may be deemed to have committed a misappropriation of the others’ trade 
secrets. The parties whose trade secrets are being misappropriated may petition for administrative corrections, and regulatory authorities may terminate any 
illegal activities and impose fines on the infringing parties.
Regulations Relating to Commercial Bribery
Pharmaceutical companies involved in a criminal investigation or administrative proceedings related to bribery are listed in the Adverse Records of 
Commercial Briberies by their respective provincial health and family planning administrative department. Pursuant to the Provisions on the Establishment
of Adverse Records of Commercial Briberies in the Medicine Purchase and Sales Industry which became effective on March 1, 2014, provincial health and 
family planning administrative departments formulate the implementing measures for establishment of Adverse Records of Commercial Briberies. Where a 
pharmaceutical company or its agent is listed in the Adverse Records of Commercial Briberies on one occasion, it will be prohibited from participating in 
the procurement bidding process or selling its products to public medical institutions located in the local provincial-level region for two years from the 
publication of the adverse records. The evaluation points of such pharmaceutical company or agent in respect of the procurement bidding process and 
procurement by public medical institutions must be credited by public medical institutions in the other provincial-level regions for two years from the 
publication of the adverse records. Where a pharmaceutical company or its agent is listed in the Adverse Records of Commercial Briberies on two or more 
occasions within five years, it will be prohibited from participating in the procurement bidding process or selling its products to all public medical 
institutions in the PRC for two years from the publication of these adverse records.
Regulations Relating to Employee Stock Incentive Plan
In February 2012, the SAFE promulgated the Notices on Issues Concerning the Foreign Exchange Administration for Domestic Individuals 
Participating in Stock Incentive Plans of Overseas Publicly Listed Companies. In accordance with this regulation and 

 
79
Table of Contents
applicable rules and regulations, PRC citizens or non-PRC citizens residing in China for a continuous period of not less than one year, who participate in 
any stock incentive plan of an overseas publicly listed company, subject to a few exceptions, are required to register with the SAFE through a domestic 
qualified agent, which could be a PRC subsidiary of such overseas listed company, and complete certain procedures. We and our employees who are PRC 
citizens or who reside in China for a continuous period of not less than one year and who participate in our stock incentive plan will be subject to such 
regulation. In addition, the State Administration of Taxation has issued circulars concerning employee share options or restricted shares. Under these 
circulars, employees working in the PRC who exercise share options, or whose restricted shares vest, will be subject to PRC individual income tax. The 
PRC subsidiaries of an overseas listed company have obligations to file documents related to employee share options or restricted shares with the tax 
authorities and to withhold individual income tax of those employees related to their share options or restricted shares. If the employees fail to pay, or the 
PRC subsidiaries fail to withhold, their individual income tax according to the laws, rules and regulations, the PRC subsidiaries may face sanctions 
imposed by the tax authorities or other PRC government authorities.
Regulations Relating to Foreign Exchange and the Dividend Distribution
Foreign Exchange Control
The State Council promulgated the PRC Regulation for the Foreign Exchange on January 29, 1996, which was amended on January 14, 1997 and 
August 5, 2008, respectively. On June 20, 1996, the People’s Bank of China promulgated the Regulation on the Administration of the Foreign Exchange 
Settlement, Sales and Payment, which came into effect on July 1, 1996. Pursuant to the above-mentioned regulations, foreign exchanges required for 
distribution of profits and payment of dividends may be purchased from designated foreign exchange banks in the PRC upon presentation of a board 
resolution authorizing the distribution of profits or payment of dividends. The Regulation on the Administration of the Foreign Exchange Settlement, Sales 
and Payment removed the previous restrictions on convertibility of foreign exchange in respect of current account items, including the distribution of 
dividends, interest and royalty payments, trade and service-related foreign exchange transactions, while foreign exchange transactions in respect of capital 
account items, such as direct investment, loan, securities investment and repatriation of investment, remain subject to the approval of the SAFE.
On November 19, 2012, the SAFE issued the Operating Rules for Foreign Exchange Issues with Regard to Direct Investment under Capital Account 
as an appendix to the Circular of the SAFE on Further Improving and Adjusting the Foreign Exchange Policies on Direct Investment, which was issued on 
November 19, 2012 and amended on May 4, 2015, October 10, 2018 and December 30, 2019, respectively. According to the Circular of the SAFE on 
Further Improving and Adjusting the Foreign Exchange Policies on Direct Investment, (i) the opening of and payment into foreign exchange accounts 
under direct investment accounts are no longer subject to approval by the SAFE; (ii) reinvestment with the legal income of foreign investors in China is no 
longer subject to approval by the SAFE; (iii) the procedures for capital verification and confirmation that foreign-funded enterprises need to go through are 
simplified; (iv) the purchase and external payment of foreign exchange under direct investment accounts are no longer subject to approval by the SAFE; (v) 
domestic transfer of foreign exchange under direct investment accounts is no longer subject to approval by the SAFE; and (vi) the administration over the 
conversion of foreign exchange capital of foreign-funded enterprises is improved. On February 13, 2015, the SAFE issued the Circular on Further 
Simplifying and Improving Foreign Exchange Administration Policies in Respect of Direct Investment, which came into effect on June 1, 2015 and was 
amended on December 30, 2019, providing that the banks, instead of the SAFE, can directly handle the foreign exchange registration and approval under 
foreign direct investment, while the SAFE and its branches indirectly supervise the foreign exchange registration and approval under foreign direct 
investment through the banks.
On March 30, 2015, the SAFE released the Circular on the Reform of the Management Method for the Settlement of Foreign Exchange Capital of 
Foreign-invested Enterprises, which came into effect on June 1, 2015 and was amended on December 30, 2019 and March 23, 2023, respectively, and 
superseded the Notice on the Relevant Operating Issues Concerning the Improvement of the Administration of Payment and Settlement of Foreign 
Currency Capital of Foreign-funded Enterprises issued by the SAFE on August 29, 2008. The Circular on the Reform of the Management Method for the 
Settlement of Foreign Exchange Capital of Foreign-invested Enterprises has made certain adjustments to some regulatory requirements on the settlement of 
foreign exchange capital of foreign-invested enterprises, and some foreign exchange restrictions provided in the Notice on the Relevant Operating Issues 
Concerning the Improvement of the Administration of Payment and Settlement of Foreign Currency Capital of Foreign-funded Enterprises. On June 9, 
2016, the SAFE issued the Circular on the Reform and Standardization of the Management Policy of the Settlement of Capital Projects, which was 
amended on December 4, 2023. Under the Circular on the Reform and Standardization of the Management Policy of the Settlement of Capital Projects and 
the Circular on the Reform of the Management Method for the Settlement of Foreign Exchange Capital of Foreign-invested Enterprises, the settlement of 
foreign exchange by foreign-invested enterprises should be governed by the policy of foreign exchange settlement on a discretionary basis. However, the 
aforementioned circulars also reiterate that the settlement of foreign exchange should only be used for its own operation purposes within the business scope 
of the foreign-invested enterprises and following the principles of authenticity.

The SAFE promulgated the Circular on Relevant Issues Concerning Foreign Exchange Control on Domestic Residents’ Offshore Investment and 
Financing and Roundtrip Investment through Special Purpose Vehicles on July 4, 2014, which requires PRC residents to register with local branches of the 
SAFE in connection with their direct establishment or indirect control of an offshore entity for the purpose of overseas investment and financing, with such 
PRC residents’ legally owned assets or equity interests in domestic enterprises or offshore assets or interests as a “special purpose vehicle” as defined 
therein. The aforesaid circular further requires amendment to the registration in the event of any significant changes with respect to the special purpose 
vehicle. Failure to comply with the SAFE registration requirements under the Circular on Relevant Issues Concerning Foreign Exchange Control on 
Domestic Residents’ Offshore Investment and Financing and Roundtrip Investment through Special Purpose Vehicles could result in liabilities under PRC 
law for evasion of foreign exchange controls. The Circular on Further Simplifying and Improving Foreign Exchange Administration Policies in Respect of 
Direct Investment, provides that local banks, instead of the SAFE, can directly handle the initial foreign exchange registration and amendment registration 
under the Circular on Relevant Issues Concerning Foreign Exchange Control on Domestic Residents’ Offshore Investment and Financing and Roundtrip 
Investment through Special Purpose Vehicles.
On April 10, 2020, SAFE promulgated the Circular on Optimizing Administration of Foreign Exchange to Support the Development of Foreign-
related Business, which allows eligible enterprises to make domestic payments using their capital funds, foreign credits and the income under capital 
accounts of overseas listing, without providing evidentiary materials concerning authenticity of such capital for banks in advance, provided that their 
capital use should be authentic and in line with provisions, and conform to the prevailing administrative regulations on the use of income under capital 
accounts. The administering bank should perform ex-post sampling in accordance with the requirements.
Dividend Distribution
Pursuant to the PRC Company Law, the latest amended edition of which came into effect on July 1, 2024, and the Foreign Investment Law of the 
PRC, foreign-invested enterprises in the PRC may pay dividends only out of their accumulated profits as determined in accordance with PRC accounting 
standards and regulations. When a foreign-invested enterprise distributes its after-tax profit for the year, ten percent of the profit should be set aside as its 
statutory surplus reserve fund. The company may no longer do so if its cumulative statutory surplus reserve accounts for more than fifty percent of its 
registered capital. If the company’s statutory surplus reserve is insufficient to make up for the losses of previous years, the company shall use the current 
year’s profit to make up for the losses before the set-aside of the statutory surplus reserve. After the company has set aside a part of its after-tax profit as its 
statutory surplus reserve, it may also set aside a part of its after-tax profit as its discretionary reserve. Distributions can be made to shareholders only after 
the remaining after-tax profit have made up for losses and the surplus reserve has been set aside.
On January 26, 2017, the SAFE issued the Notice on Improving the Check of Authenticity and Compliance to Further Promote Foreign Exchange 
Control, which stipulates several capital control measures with respect to outbound remittance of profits from domestic entities to offshore entities, 
including the following: (i) under the principle of genuine transaction, banks should check board resolutions regarding profit distribution, the original 
version of tax filing records and audited financial statements; and (ii) domestic entities should hold income to account for previous years’ losses before 
remitting the profits. Moreover, domestic entities should provide detailed explanations of the sources of capital and the utilization arrangements and board 
resolutions, contracts and other proof when completing the registration procedures in connection with an outbound investment.
Regulations Relating to Enterprise Income Tax
Pursuant to the Enterprise Income Tax Law of the PRC effective as of January 1, 2008 and as amended on February 24, 2017 and December 29, 2018, 
respectively, the income tax rate for both domestic and foreign-invested enterprises is 25% with certain exceptions. To clarify certain provisions in the 
Enterprise Income Tax Law, the State Council promulgated the Implementation Rules of the Enterprise Income Tax Law on December 6, 2007, which was 
amended on April 23, 2019 and December 6, 2024, respectively. Under the Enterprise Income Tax Law and the Implementation Rules of the Enterprise 
Income Tax Law, enterprises are classified as either “resident enterprises” or “non-resident enterprises.” Besides enterprises established within the PRC, 
enterprises established outside of China whose “de facto management bodies” are located in China are considered “resident enterprises” and subject to the 
uniform 25% enterprise income tax rate for their global income. In addition, the Enterprise Income Tax Law provides that a non-resident enterprise refers 
to an entity established under foreign law whose “de facto management bodies” are not within the PRC, but has an establishment or place of business in the 
PRC, or does not have an establishment or place of business in the PRC but has income sourced within the PRC.
The Implementation Rules of the Enterprise Income Tax Law provide that since January 1, 2008, an income tax rate of 10% should normally be 
applicable to dividends declared to non-PRC resident enterprise investors that do not have an establishment or place of business in the PRC, or have an 
establishment or place of business but the income is not effectively connected with the establishment or place of business, to the extent such dividends are 
derived from sources within the PRC. The income tax on the dividends may be reduced pursuant to a tax treaty between China and the jurisdictions in 
which the non-PRC resident enterprise shareholders reside.

Regulations Relating to Outbound Data Transfer
On July 7, 2022, the CAC promulgated the Measures on Security Assessment of Outbound Data Transfer, which became effective on September 1, 
2022 and provided that data processors satisfying certain conditions are required to apply for security assessment through provincial cyberspace 
administrations and obtain approval from the CAC.
On February 22, 2023, the CAC promulgated the Measures on Standard Contracts for Outbound Transfer of Personal Information, which became 
effective on June 1, 2023 and provided that personal information processors that carry out personal information outbound transfer activities by way of 
entering into standard contracts shall comply with certain conditions, and file the standard contracts with the provincial cyberspace administrations.
On March 22, 2024, the CAC promulgated the Provisions on Promoting and Regulating Cross-Border Data Flows, which became effective on the 
same day and further adjusted the scope and procedures applicable to the mechanisms of security assessment and filing of standard contracts, and provided 
exemption conditions. Pursuant to the Provisions on Promoting and Regulating Cross-Border Data Flows, if a data processor transfers data out of China 
and falls within any of the following circumstances, security assessment shall apply: (i) a critical information infrastructure operator provides personal 
information or important data out of China, or (ii) a data processor other than a critical information infrastructure operator provides important data out of 
China, or provides personal information (excluding sensitive personal information) of more than 1 million individuals or sensitive personal information of 
more than 10,000 individuals out of China cumulatively from January 1 of the current year. However, the data processor will not be required to apply for 
such security assessment if certain exemption conditions are met.
Other PRC National- and Provincial-Level Laws and Regulations
We are subject to changes to many other laws and regulations administered by governmental authorities at the national, provincial and municipal 
levels, some of which are or may become applicable to our business, including the regulations governing the confidentiality of patients’ medical 
information and setting forth the circumstances under which the patients’ medical information may be released for inclusion in our databases, or released 
by us to third parties, which, may become more restrictive in the future.
We also comply with numerous additional national and provincial laws and regulations relating to matters such as safe working conditions, 
manufacturing practices, environmental protection and fire hazard control. We believe that we are currently in compliance with these laws and regulations; 
however, we may be required to incur significant costs to comply with these laws and regulations in the future. Unanticipated changes in existing 
regulatory requirements or adoption of new requirements could therefore have a material adverse effect on our business, results of operations and financial 
condition.
U.S. Regulation
Government Regulation and Product Approval in the United States
The FDA and other regulatory authorities in the United States at federal, state and local levels, as well as in foreign countries, extensively regulate, 
among other things, the research, development, testing, manufacture, quality control, import, export, safety, effectiveness, labeling, packaging, storage, 
distribution, recordkeeping, approval, advertising, promotion, marketing, post-approval monitoring and post-approval reporting of drug and biological 
products. Along with third-party contractors, we are required to navigate the various preclinical, clinical and commercial approval requirements of the 
governing regulatory agencies of the countries in which we wish to conduct studies or seek approval or licensure of our drug candidates. The processes for 
obtaining regulatory approvals in the United States and in foreign jurisdictions, along with subsequent compliance with applicable laws and regulations and 
other regulatory authorities, require the expenditure of substantial time and financial resources.
Government policies may change and additional government regulations may be enacted that could prevent or delay further development or regulatory 
approval of any of our drug candidates, or anticipated manufacturing processes, disease indications, or labeling. We cannot predict the likelihood, nature or 
extent of government regulation that might arise from future legislative or administrative action.
Review and Approval for Licensing Biologics in the United States
In the United States, the FDA regulates our current drug candidates as biological products, or biologics, under the Federal Food, Drug, and Cosmetic 
Act (the “FDCA”), the Public Health Service Act and associated implementing regulations. Biologics, like other drugs, are used for the treatment, 
prevention or cure of disease in humans. In contrast to chemically synthesized small molecular weight drugs, which have a well-defined structure and can 
be thoroughly characterized, biologics are generally derived from living material 

 
82
Table of Contents
(human, animal, or microorganism) and are complex in structure, and thus are usually not fully characterized. Biologics include immuno-oncology 
therapeutics for the treatment of cancer and other diseases.
Biologics are also subject to other federal, state and local statutes and regulations. The failure to comply with applicable statutory and regulatory 
requirements at any time during the product development process, approval process or after approval may subject a sponsor or applicant to administrative 
or judicial enforcement actions. These actions could include the suspension or termination of clinical trials by the FDA, the FDA’s refusal to approve 
pending applications or supplemental applications, withdrawal of an approval, “Warning Letters” (official messages from the FDA to a manufacturer or 
other organization that it has violated some rule in a federally regulated activity) or “Untitled Letters” (initial correspondences from the FDA with a 
regulated industry that cite violations that do not meet the threshold of regulatory significance for a Warning Letter and request correction of the violation), 
product recalls, product seizures, total or partial suspension of production or distribution, import detention, injunctions, fines, refusals of government 
contracts, restitution, disgorgement of profits, or civil or criminal investigations and penalties brought by the FDA, the Department of Justice, or other 
governmental entities.
An applicant seeking approval to market and distribute a biologic in the United States typically must undertake the following:
•
completion of non-clinical laboratory tests and animal studies performed in accordance with the FDA’s good laboratory practice regulations;
•
submission to the FDA of an application for an Investigational New Drug, or an IND, which must become effective before clinical trials may 
begin and must be updated annually or when significant changes are made;
•
manufacture, labeling and distribution of an investigational drug in compliance with current good manufacturing practice;
•
approval by an independent institutional review board or ethics committee at each clinical site before each clinical trial may be initiated;
•
performance of adequate and well-controlled human clinical trials in accordance with the FDA’s current Good Clinical Practices requirements, to 
establish the safety, purity and potency of the proposed biological drug candidate for its intended purpose;
•
preparation of and submission to the FDA of a biologics license application, after completion of all pivotal clinical trials requesting marketing 
approval for one or more proposed indications;
•
payment of application user fees under the Prescription Drug User Fee Act;
•
satisfactory completion of an FDA Advisory Committee review, where appropriate or if applicable, as may be requested by the FDA to assist 
with its review;
•
satisfactory completion of one or more FDA inspections of the manufacturing facility or facilities at which the proposed product, or components 
thereof, are produced to assess compliance with current good manufacturing practice and data integrity requirements to assure that the facilities, 
methods and controls are adequate to preserve the biologic’s identity, safety, quality, purity and potency;
•
satisfactory completion of FDA audits of selected clinical investigation sites to assure compliance with current Good Clinical Practices 
requirements and the integrity of the clinical data;
•
obtaining FDA review and approval of the biologics license application to permit commercial marketing of the licensed biologic for particular 
indications for use in the United States; and
•
compliance with any post-approval requirements, including the potential requirement to implement a Risk Evaluation and Mitigation Strategy, 
and the potential requirement to conduct post-approval studies.
The testing and approval process requires substantial time, effort and financial resources and we cannot be certain that any approvals for our drug 
candidates will be granted on a timely basis, if at all.
From time to time, legislation is drafted, introduced and passed in the Congress of the United States that could significantly change the statutory 
provisions governing the testing, approval, manufacturing and marketing of products regulated by the FDA. In addition to 

 
83
Table of Contents
new legislation, FDA regulations and policies are often revised or interpreted by the agency in ways that may significantly affect our business and our drug 
candidates. It is impossible to predict whether further legislative changes will be enacted or whether FDA regulations, guidance, policies or interpretations 
will be changed or what the effect of such changes, if any, may be.
Preclinical and Clinical Development in the United States
Before an applicant of a biologics license application can begin testing the potential asset in human subjects, the applicant must first conduct 
preclinical studies. Preclinical studies include laboratory evaluations of product chemistry, toxicity and formulation, as well as in vitro and animal studies 
to assess the potential safety and activity of the biologic for initial testing in humans and to establish a rationale for therapeutic use. Preclinical studies are 
subject to federal regulations and requirements, including good laboratory practice regulations. The results of an applicant’s preclinical studies are 
submitted to the FDA as part of an IND.
An IND is a request for authorization from the FDA to administer an investigational new drug product to humans. An IND is an exemption from the 
FDCA that allows an unapproved drug to be shipped in interstate commerce for use in an investigational clinical trial. Such authorization must be secured 
prior to interstate shipment. In support of a request for an IND, applicants must submit a range of information, including preclinical data, manufacturing 
information and a detailed protocol for each clinical trial. Any subsequent protocol amendments must be submitted to the FDA as part of the IND.
Human clinical trials may not begin until an IND is effective. The IND automatically becomes effective 30 days after receipt by the FDA, unless the 
FDA raises safety concerns or questions about the proposed clinical trial within the 30-day time period. In such a case, the IND may be placed on clinical 
hold and the IND sponsor and the FDA must resolve any outstanding concerns or questions before the clinical trial can begin. Submission of an IND 
therefore may or may not result in FDA authorization to begin a clinical trial.
The FDA may also place a clinical hold or partial clinical hold on such trial following commencement of a clinical trial under an IND. A clinical hold 
is an order issued by the FDA to the sponsor to delay a proposed clinical investigation or to suspend an ongoing investigation. A partial clinical hold is a 
delay or suspension of only part of the clinical work requested under the IND. For example, a specific protocol or part of a protocol is not allowed to 
proceed, while other protocols may do so. No more than 30 days after the imposition of a clinical hold or partial clinical hold, the FDA will provide the 
sponsor with a written explanation of the basis for the hold. Following issuance of a clinical hold or partial clinical hold, an investigation may only resume 
after the FDA has notified the sponsor that the investigation may proceed. The FDA will base that determination on information provided by the sponsor 
correcting the deficiencies previously cited or otherwise satisfying the FDA that the investigation can proceed.
Clinical trials involve the administration of the investigational product to human subjects under the supervision of qualified investigators in 
accordance with regulations of current Good Clinical Practices, which include the requirement that all research subjects provide their informed consent for 
their participation in any clinical trial. Clinical trials are conducted under protocols detailing, among other things, the objectives of the study, the 
parameters to be used in monitoring safety and the effectiveness criteria to be evaluated. A separate submission to the existing IND must be made for each 
successive clinical trial conducted during product development and for any subsequent protocol amendments.
A sponsor may choose, but is not required, to conduct a foreign clinical trial under an IND. When a foreign clinical trial is conducted under an IND, 
all FDA IND requirements must be met unless waived. When the foreign clinical trial is not conducted under an IND, the sponsor must ensure that the 
study complies with regulations of current Good Clinical Practices in order to use the study as support for an IND or application for marketing approval, 
including review and approval by an independent ethics committee and informed consent from subjects.
Furthermore, an independent institutional review board for each site proposing to conduct the clinical trial must review and approve the plan for any 
clinical trial and its informed consent form before the clinical trial begins at that site, and must monitor the study until completed. Regulatory authorities, 
the institutional review board or the sponsor may suspend a clinical trial at any time on various grounds, including a finding that the subjects are being 
exposed to an unacceptable health risk or that the trial is unlikely to meet its stated objectives.
Some trials also include oversight by an independent group of qualified experts organized by the clinical trial sponsor, known as a data safety 
monitoring board. Data safety monitoring boards provide authorization for whether or not a trial may move forward at designated check points based on 
access to certain data from the trial and may halt the clinical trial if a data safety monitoring board determines that there is an unacceptable safety risk for 
subjects or based on other grounds, such as no demonstration of efficacy. Other grounds for suspension or termination may be made based on evolving 
business objectives and/or competitive climate. There are also requirements governing the reporting of ongoing clinical trials and clinical trial results to 
public registries.

Clinical Trials
For purposes of approval of biologics license applications, clinical trials are typically conducted in the following sequential phases that may overlap or 
be combined:
•
Phase 1: The investigational product is initially introduced into a small number of healthy human subjects or patients with the target disease or 
condition. These trials are designed to test the safety, dosage tolerance, absorption, metabolism and distribution of the investigational product in 
humans and the side effects associated with increasing doses.
•
Phase 2: The investigational product is administered to a limited patient population with a specified disease or condition to evaluate the 
preliminary efficacy, optimal dosages and dosing schedule and to identify possible adverse side effects and safety risks. Multiple Phase 2 clinical 
trials may be conducted to obtain information prior to beginning larger and more expensive Phase 3 clinical trials.
•
Phase 3: The investigational product is administered to an expanded patient population generally at multiple geographically dispersed clinical 
trial sites to further evaluate dosage, to provide statistically significant evidence of clinical efficacy and to further test for safety. These clinical 
trials are intended to generate sufficient data to statistically evaluate the efficacy and safety of the product for approval, to establish the overall 
risk/benefit ratio of the investigational product and to provide an adequate basis for product approval by the FDA.
In some cases, the FDA may require, or companies may voluntarily pursue, additional clinical trials after a product is approved to gain more 
information about the product, referred to as Phase 4 trials. Such post-approval trials, when applicable, are conducted following initial approval, typically to 
develop additional data and information relating to the biological characteristics of the product and treatment of patients in the intended therapeutic 
indication.
Progress reports detailing the results of the clinical trials must be submitted at least annually to the FDA and more frequently if serious adverse events 
occur. In addition, IND safety reports must be submitted to the FDA for any of the following: suspected serious and unexpected adverse reactions; findings 
from epidemiological studies, pooled analysis of multiple studies, animal or in vitro testing, or other clinical trials, whether or not conducted under an IND, 
and whether or not conducted by the sponsor, that suggest a significant risk in humans exposed to the drug; and any clinically important increase in the rate 
of a serious suspected adverse reaction over such rate listed in the protocol or investigator brochure, which is a comprehensive document summarizing the 
body of information about an investigational product obtained during clinical and non-clinical trials.
Each of Phase 1, Phase 2 and Phase 3 clinical trials may not be completed successfully within any specified period, or at all. Furthermore, the FDA or 
the sponsor may suspend or terminate a clinical trial at any time on various grounds, including a finding that the research patients are being exposed to an 
unacceptable health risk. Similarly, an independent institutional review board can suspend or terminate approval of a clinical trial at its institution, or an 
institution it represents, if the clinical trial is not being conducted in accordance with the institutional review board’s requirements or if the drug has been 
associated with unexpected serious harm to patients. 
Concurrently with clinical trials, companies often complete additional animal studies, and develop additional information about the chemistry and 
physical characteristics of the drug and finalize a process for manufacturing the product in commercial quantities in accordance with requirements of Good 
Manufacturing Practice. The manufacturing process must be capable of consistently producing quality batches of the drug candidate and, among other 
things, must develop methods for testing the identity, strength, quality, purity and potency of the final drug. Additionally, appropriate packaging must be 
selected and tested and stability studies must be conducted to demonstrate that the drug candidate does not undergo unacceptable deterioration over its shelf 
life.
BLA Submission and Review
Assuming successful completion of all required clinical testing in accordance with all applicable regulatory requirements, an applicant may submit a 
biologics license application, or BLA, requesting licensing to market the biologic for one or more indications in the United States. The BLA must include 
the results of product development, non-clinical studies and clinical trials; detailed information on the product’s chemistry, manufacture and controls; and 
proposed labeling. Under the Prescription Drug User Fee Amendments, a BLA submission is subject to an application user fee, unless a waiver or 
exemption applies.
The FDA will initially review the BLA for completeness before accepting it for filing. Under the FDA’s procedures, the agency has 60 days from its 
receipt of a BLA to determine whether the application will be accepted for filing and substantive review. If the agency determines that the application does 
not meet this initial threshold standard, the FDA may refuse to file the application and request 

 
85
Table of Contents
additional information, in which case the application must be resubmitted with the requested information and review of the application delayed.
With certain exceptions, BLAs must include a pediatric assessment, generally based on clinical trial data, of the safety and effectiveness of the 
biologic in relevant pediatric populations. Under certain circumstances, the FDA may waive or defer the requirement for a pediatric assessment, either at 
the sponsor’s request or by the agency’s initiative.
After the BLA is accepted for filing, the FDA reviews the BLA to determine, among other things, whether a product is safe, pure and potent and if the 
facility in which it is manufactured, processed, packed or held meets standards designed to assure the product’s continued identity, strength, quality, safety, 
purity and potency. The FDA may convene an advisory committee to provide clinical insight on application review questions. Before approving a BLA, the 
FDA will typically inspect the facility or facilities where the product is manufactured. The FDA will not approve an application unless it determines that 
the manufacturing processes and facilities comply with current Good Manufacturing Practice and are adequate to ensure consistent production of the 
product within required specifications. In addition, the FDA expects that all data be reliable and accurate, and requires sponsors to implement meaningful 
and effective strategies to manage data integrity risks. Data integrity is an important component of the sponsor’s responsibility to ensure the safety, efficacy 
and quality of its product or products.
The FDA will typically inspect one or more clinical sites to assure compliance with regulations of current Good Clinical Practices before approving a 
BLA. If the FDA determines that the application, manufacturing process or manufacturing facilities are not acceptable, it will outline the deficiencies in the 
submission and often will request additional testing or information. Notwithstanding the submission of any requested additional information, the FDA 
ultimately may decide that the application does not satisfy the regulatory criteria for approval.
FDA performance goals generally provide for action on a BLA within ten months of filing, which typically occurs within 60 days of submission, but 
that deadline is extended in certain circumstances. Furthermore, the review process is often significantly extended by FDA requests for additional 
information or clarification.
The FDA may refer applications for novel products or products that present difficult questions of safety or efficacy to an advisory committee. 
Typically, an advisory committee consists of a panel that includes clinicians and other experts who will review, evaluate and provide a recommendation as 
to whether the application should be approved and, if so, under what conditions. The FDA is not bound by the recommendations of an advisory committee, 
but it considers such recommendations carefully when making decisions and usually has followed such recommendations.
After the FDA evaluates a BLA and conducts inspections of manufacturing facilities where the investigational product and/or its components will be 
produced, the FDA may issue an approval letter or a complete response letter. An approval letter authorizes commercial marketing of the biologic with 
specific prescribing information for specific indications. A complete response letter will describe all of the deficiencies that the FDA has identified in the 
BLA, except that where the FDA determines that the data supporting the application are inadequate to support approval, the FDA may issue the complete 
response letter without first conducting required inspections, testing submitted product lots and/or reviewing proposed labeling. If and when the 
deficiencies have been addressed to the FDA’s satisfaction in a resubmission of the BLA, the FDA will issue an approval letter. In issuing the complete 
response letter, the FDA may recommend actions that the applicant might take to place the BLA in condition for approval, including requests for additional 
data, information or clarification. The FDA may delay or refuse approval of a BLA if applicable regulatory criteria are not satisfied, and may require 
additional testing or information and/or require post-marketing studies and clinical trials. Even with submission of this additional information, the FDA 
ultimately may decide that the application does not satisfy the regulatory criteria for approval.
During the approval process, the FDA will determine whether a Risk Evaluation and Mitigation Strategy, (“REMS”), is necessary to ensure the safe 
use of the biologic. A REMS is a safety strategy to manage a known or potential serious risk associated with a product and to enable patients to have 
continued access to such medicines by managing their safe use, and could include medication guides, physician communication plans or elements to assure 
safe use, such as restricted distribution methods, patient registries and other risk minimization tools. If the FDA concludes that a REMS is needed, the BLA 
sponsor must submit a proposed REMS and the FDA will not approve the BLA without a REMS that the agency has determined is acceptable.
In addition, under the Pediatric Research Equity Act, certain applications or supplements must contain data that are adequate to assess the safety and 
effectiveness of the drug for the claimed indications in all relevant pediatric subpopulations, and to support dosing and administration for each pediatric 
subpopulation for which the product is safe and effective. The FDA may, on its own initiative or at the request of the applicant, grant deferrals for 
submission of some or all pediatric data until after approval of the product for use in adults, or full or partial waivers from the pediatric data requirements.

Table of Contents
If the FDA approves a product, it may limit the approved indications for use for the product, or require that contraindications, warnings or precautions 
be included in the product labeling. The FDA may also require that post-approval studies, including Phase 4 clinical trials, be conducted to further assess 
the drug’s safety after approval. The FDA may prevent or limit further marketing of a product based on the results of post-marketing studies or surveillance 
programs.
The FDA may also require testing and surveillance programs to monitor the product after commercialization. For biologics, such testing may include 
official lot release, which requires the manufacturer to perform certain tests on each lot of the product before it is released for distribution. The 
manufacturer then typically must submit samples of each lot of product to the FDA, together with a release protocol showing a summary of the history of
manufacture of the lot and the results of all of the manufacturer’s tests performed on the lot. The FDA may also perform certain confirmatory tests on lots 
of some products itself, before releasing the lots for distribution by the manufacturer.
After approval, many types of changes to the approved product, such as adding new indications, manufacturing changes and additional labeling 
claims, are often subject to further testing requirements and FDA review and approval, depending on the nature of the post-approval change. The FDA may 
withdraw the product approval if compliance with pre- and post-marketing requirements is not maintained or if problems occur after the product reaches 
the marketplace.
Post-Approval Requirements
Any products manufactured or distributed pursuant to FDA approvals are subject to pervasive and continuing regulation by the FDA, including, 
among other things, requirements relating to recordkeeping, periodic reporting, reporting of certain deviations and adverse experiences, product sampling 
and distribution and advertising and promotion of the product. After approval, most changes to the approved product, such as adding new indications or 
other labeling claims, are subject to FDA review and approval. There also are continuing user fee requirements, under which the FDA assesses an annual 
program fee for each product identified in an approved BLA. Biologic manufacturers and their third-party contractors are required to register their 
establishments with the FDA and certain state agencies. These establishments are subject to routine and periodic unannounced inspections by the FDA and 
certain state agencies for compliance with current Good Manufacturing Practice and data integrity requirements, which impose certain procedural and 
documentation requirements to assure quality of manufacturing and product. Requirements with respect to data integrity include, among other things, 
controls to ensure data are complete and secure; activities documented at the time of performance; audit trail functionality; authorized access and 
limitations; validated computer systems; and review of records for accuracy, completeness and compliance with established standards.
Post-approval changes to the manufacturing process are strictly regulated, and, depending on the significance of the change, may require FDA 
approval before being implemented. FDA regulations also require investigation and correction of any deviations from current good manufacturing practice 
and impose reporting requirements upon us and any third-party manufacturers that we may decide to use. Accordingly, manufacturers must continue to 
expend time, money and effort in the area of production and quality control to maintain compliance with current good manufacturing practice, data 
integrity, pharmacovigilance (i.e., post-marketing safety reporting obligations) and other aspects of regulatory compliance.
The FDA may withdraw a product approval if compliance with regulatory requirements and standards is not maintained or if problems occur after the 
product reaches the market. Later discovery of previously unknown problems with a product, including adverse events of unanticipated severity or 
frequency, or with manufacturing processes, or failure to comply with regulatory requirements, may result in revisions to the approved labeling to add new 
safety information; imposition of post-approval studies or clinical trials to assess new safety risks; or imposition of distribution or other restrictions under a 
Risk Evaluation and Mitigation Strategy. Other potential consequences include:
•
restrictions on the marketing or manufacturing of a product, complete withdrawal of the product from the market or product recalls;
•
fines, Warning Letters, Untitled Letters or holds on post-approval clinical trials;
•
refusal of the FDA to approve pending applications or supplements to approved applications, or suspension or revocation of existing product 
approvals;
•
product seizure or detention, or refusal of the FDA to permit the import or export of products that it believes present safety problems by issuing 
an Import Alert;
•
permanent injunctions and consent decrees, including the imposition of civil or criminal penalties; or

•
voluntary product recall.
The FDA strictly regulates the marketing, labeling, advertising and promotion of prescription drug products placed on the market. A company can 
make only those claims relating to safety and efficacy, purity and potency that are approved by the FDA and in accordance with the provisions of the 
approved label. The FDA’s regulation includes, among other things, standards and regulations for direct-to-consumer advertising, communications 
regarding unapproved uses, industry-sponsored scientific and educational activities and promotional activities involving the Internet and social media. 
Promotional claims relating to a product’s safety or effectiveness are prohibited before the drug is approved. After approval, a product generally may not be 
promoted for uses that are not approved by the FDA, as reflected in the product’s prescribing information. In the United States, healthcare professionals are 
generally permitted to prescribe drugs for such uses not described in the drug’s labeling, known as off-label uses, because the FDA does not regulate the 
practice of medicine. However, FDA regulations impose rigorous restrictions on manufacturers’ communications, prohibiting the promotion of off-label 
uses. It may be permissible, under very specific, narrow conditions, for a manufacturer to engage in non-promotional, non-misleading communication 
regarding off-label information, such as distributing scientific or medical journal information. 
If a company is found to have promoted off-label uses, it may become subject to adverse public relations and administrative and judicial enforcement 
by the FDA, the U.S. Department of Justice or the Office of the Inspector General of the Department of Health and Human Services, as well as other 
federal and state authorities. This could subject a company to a range of penalties that could have a significant commercial impact, including civil and 
criminal fines and agreements that materially restrict the manner in which a company promotes or distributes products. The federal government has levied 
large civil and criminal fines against companies for alleged improper promotion, and has also requested that companies enter into consent decrees and 
permanent injunctions under which specified promotional conduct is changed or curtailed.
The distribution of prescription drugs and biologics are subject to the Drug Supply Chain Security Act, which requires manufacturers and other 
stakeholders to comply with product identification, tracing, verification, detection and response, notification and licensing requirements. In addition, the 
Prescription Drug Marketing Act, and its implementing regulations, and state laws limit the distribution of prescription pharmaceutical product samples, 
and the Drug Supply Chain Security Act imposes requirements to ensure accountability in distribution and to identify and remove prescription drug and 
biological products that may be counterfeit, stolen, contaminated, or otherwise harmful from the market.
Patent Term Restoration and Marketing Exclusivity
After approval, owners of biological product patents may apply for up to a five-year patent term extension to restore a portion of patent term lost 
during product development and FDA review of a BLA if approval of the application is the first permitted commercial marketing or use of a biologic 
containing the active ingredient under the Hatch-Waxman Amendments. The allowable patent term extension is calculated as one-half of the product’s 
testing phase, which is the time between IND and BLA submission, and all of the review phase, which is the time between BLA submission and approval, 
up to a maximum of five years. The time can be shortened if the FDA determines that the applicant did not pursue approval with due diligence. The total 
patent term after the extension may not exceed more than 14 years from the date of FDA approval of the product. Only one patent claiming each approved 
product is eligible for restoration and the patent holder must apply for restoration within 60 days of approval. The United States Patent and Trademark 
Office, in consultation with the FDA, reviews and approves the application for patent term restoration.
For patents that might expire during the application phase, the patent owner may request an interim patent extension. An interim patent extension 
increases the patent term by one year and may be renewed up to four times. For each interim patent extension granted, the post-approval patent extension is 
reduced by one year. The director of the United States Patent and Trademark Office must determine that approval of the biological drug candidate covered 
by the patent for which a patent extension is being sought is likely. Interim patent extensions are not available for a biological drug candidate for which a 
BLA has not been submitted.
Expedited Development and Review Programs
The FDA is required to facilitate the development and expedite the review of pharmaceutical products that are intended for the treatment of a serious 
or life-threatening condition for which there is no effective treatment and which demonstrate the potential to address unmet medical need for the condition. 
Under the fast track program, the sponsor of a new drug candidate may request the FDA to designate the product for a specific indication as a fast track 
product concurrent with or after the filing of the IND for the drug candidate. The FDA must determine if the drug candidate qualifies for fast track 
designation within 60 days after receipt of the sponsor’s request.
In addition to other benefits, such as the ability to have more frequent interactions with the FDA, the agency may initiate review of sections of a fast 
track product’s BLA before the application is complete. This rolling review is available if the applicant provides and 

 
88
Table of Contents
the FDA approves a schedule for the submission of the remaining information and the applicant pays applicable user fees. However, the FDA’s review 
period for a fast track application does not begin until the last section of the BLA is submitted. In addition, the fast track designation may be withdrawn by 
the FDA if the agency believes that the designation is no longer supported by data emerging in the clinical trial process.
Healthcare Regulation
Pharmaceutical Coverage and Reimbursement
Significant uncertainty exists as to the coverage and reimbursement status of any products for which we may obtain regulatory approval. In the United 
States, sales of any products for which we may receive regulatory approval for commercial sale will depend in part on the availability of coverage and 
reimbursement from third-party payors. Third-party payors include government authorities, managed care providers, private health insurers and other 
organizations. Third-party payors establish the coverage and reimbursement policies for pharmaceutical products, and the marketability of any products for 
which we may receive regulatory approval for commercial sale depends on those payors’ coverage policies and reimbursement rates. Third-party payors 
may limit coverage to specific products on an approved list, or formulary, which might not include one or more of our drug candidates, if approved. Third-
party payors, together with regulators and others, are increasingly challenging the prices charged for pharmaceutical products and health services, in 
addition to their cost-effectiveness, safety and efficacy.
In addition, no uniform policy for coverage and reimbursement exists in the United States. Third-party payors often rely upon Medicare coverage 
policy and payment limitations in setting their own coverage and reimbursement policies, but also have their own methods and approval process apart from 
Medicare determinations. Therefore, coverage and reimbursement rates can vary significantly from payor to payor. Further, coverage policies and third-
party payor reimbursement rates may change at any time. Even if favorable coverage and reimbursement status is attained for a product for which we 
receive regulatory approval, less favorable coverage policies and reimbursement rates may be implemented in the future.
Moreover, obtaining coverage and adequate reimbursement is a time-consuming and costly process. We may be required to provide scientific and 
clinical support for the use of any product to each third-party payor separately with no assurance that approval will be obtained, and we may need to 
conduct expensive pharmacoeconomic studies in order to demonstrate the cost-effectiveness of our products. We cannot be certain that our drug candidates 
will be considered cost-effective by third-party payors. This process could delay the market acceptance of any drug candidates for which we may receive 
approval and could have a negative effect on our future revenues and operating results.
Other U.S. Healthcare Laws and Compliance Requirements
In the United States, our business may be subject to healthcare fraud and abuse regulation and enforcement by both the federal government and the 
states in which we conduct our business, particularly once third-party reimbursement becomes available for one or more of our products. The healthcare 
fraud and abuse laws and regulations that may affect our ability to operate include:
•
The federal Anti-Kickback Statute, which prohibits, among other things, knowingly and willfully soliciting, receiving, offering or paying any 
remuneration (including any kickback, bribe or rebate), directly or indirectly, overtly or covertly, in cash or in kind, to induce, or in return for, 
either the referral of an individual, or the purchase, lease, order or recommendation of any good, facility, item or service for which payment may 
be made, in whole or in part, under the Medicare and Medicaid programs, or other federal healthcare programs;
•
The federal civil and criminal false claims laws and civil monetary penalty laws, including the civil False Claims Act, which prohibits, among 
other things, knowingly presenting, or causing to be presented, claims for payment of government funds that are false or fraudulent, or 
knowingly making, or using or causing to be made or used, a false record or statement material to a false or fraudulent claim to avoid, decrease, 
or conceal an obligation to pay money to the federal government;
•
The federal Health Insurance Portability and Accountability Act of 1996, which, among other things, prohibits executing a scheme to defraud 
any healthcare benefit program, including private third-party payors, and prohibits (i) knowingly and willfully falsifying, concealing or covering 
up a material fact or making any materially false, fictitious or fraudulent statement or representation and (ii) making or using any false writing or 
document knowing the same to contain any materially false, fictitious or fraudulent statement or entry in connection with the delivery of or 
payment for healthcare benefits, items or services;

 
89
Table of Contents
•
The Health Insurance Portability and Accountability Act of 1996, as amended by the Health Information Technology for Economic and Clinical 
Health Act of 2009, and their respective implementing regulations, which impose requirements relating to the privacy, security and transmission 
of individually identifiable health information held by covered entities, including health plans, healthcare clearinghouses and certain healthcare 
providers, and their business associates, individuals or entities that perform certain services on behalf of a covered entity that involve the use or 
disclosure of individually identifiable health information, and their covered subcontractors. The Health Information Technology for Economic 
and Clinical Health Act of 2009 also created new tiers of civil monetary penalties, amended Health Insurance Portability and Accountability Act 
of 1996 to make civil and criminal penalties directly applicable to business associates and gave state attorneys general new authority to file civil 
actions for damages or injunctions in federal courts to enforce the Health Insurance Portability and Accountability Act of 1996 and seek 
attorneys’ fees and costs associated with pursuing federal civil actions;
•
The federal Physician Payments Sunshine Act, being implemented as the Open Payments Program, which requires manufacturers of drugs, 
devices, biologics and medical supplies for which payment is available under Medicare, Medicaid or the Children’s Health Insurance Program 
(with certain exceptions) to report annually to the Centers for Medicare and Medicaid Services, information related to direct or indirect payments 
and other transfers of value to physicians, certain other non-physician health care professionals (such as physicians assistants and nurse 
practitioners), and teaching hospitals, as well as ownership and investment interests held in a company by physicians and their immediate family 
members; and
•
U.S. state and local laws and regulations, such as state anti-kickback and false claims laws, which may apply to sales or marketing arrangements 
and claims involving healthcare items or services reimbursed by non-governmental third-party payors, including private insurers; state laws that 
require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the compliance guidance 
promulgated by the federal government or otherwise restrict payments that may be made to healthcare providers; state laws that restrict the 
ability of manufacturers to offer co-pay support to patients for certain prescription drugs; state laws that require drug manufacturers to report 
information related to clinical trials, or information related to payments and other transfers of value to physicians and other healthcare providers 
or marketing expenditures; state laws that require drug manufacturers to report information on the pricing of certain drugs; state laws and local 
ordinances that require identification or licensing of sales representatives; and state laws governing the privacy and security of health information 
in certain circumstances, many of which differ from each other in significant ways and often are not preempted by the Health Insurance 
Portability and Accountability Act of 1996, thus complicating compliance efforts.
We will be required to spend substantial time and money to ensure that our business arrangements with third parties comply with applicable 
healthcare laws and regulations. Even then, governmental authorities may conclude that our business practices do not comply with current or future 
statutes, regulations or case law involving applicable fraud and abuse or other healthcare laws and regulations. If governmental authorities find that our 
operations violate any of these laws or any other governmental regulations that may apply to us, we may be subject to significant civil, criminal and 
administrative penalties, damages, fines, disgorgement, individual imprisonment, exclusion from government funded healthcare programs, such as 
Medicare and Medicaid, and additional reporting obligations and oversight if we become subject to a corporate integrity agreement or other agreement to 
resolve allegations of non-compliance with these laws, and we may be required to curtail or restructure our operations. Moreover, we expect that there will 
continue to be federal and state laws and regulations, proposed and implemented, that could impact our operations and business. In addition, the approval 
and commercialization of any drug candidate we develop outside the United States will also likely subject us to foreign equivalents of the healthcare laws 
mentioned above, among other foreign laws. The extent to which future legislation or regulations, if any, relating to health care fraud and abuse laws or 
enforcement, may be enacted or what effect such legislation or regulation would have on our business remains uncertain.
Healthcare Reform
In the United States there have been, and continue to be, several legislative and regulatory changes and proposed reforms of the healthcare system to 
contain costs, improve quality and expand access to care. In the United States, there have been and continue to be a number of healthcare-related legislative 
initiatives that have significantly affected the pharmaceutical industry. For example, the Patient Protection and Affordable Care Act, as amended by the 
Health Care and Education Reconciliation Act of 2010 in March 2010 (collectively, the “ACA”), substantially changing the way healthcare is financed by
both governmental and private insurers and significantly impacting the U.S. pharmaceutical industry. Since its enactment, there have been congressional, 
judicial, and executive challenges and amendments to the ACA, which have resulted in delays in the implementation of, and action taken to repeal or 
replace, certain aspects of the ACA. For example, on August 16, 2022, the Inflation Reduction Act of 2022 (the “IRA”) was signed into law, which among 
other things, extends enhanced subsidies for individuals purchasing health insurance coverage in ACA marketplaces through plan year 2025. The IRA also 
eliminates the “donut hole” under the Medicare Part D program beginning in 2025 by significantly lowering the beneficiary maximum out-of-pocket cost 
through a newly established manufacturer discount program. It is possible that the ACA will be subject to judicial or Congressional challenges or additional 
health reform measures of the second Trump administration will impact the ACA and our business.

 
90
Table of Contents
Additionally, there has been increasing legislative and enforcement interest in the United States with respect to specialty drug pricing practices. 
Specifically, there have been several U.S. Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, 
bring more transparency to drug pricing; reduce the cost of prescription drugs under Medicare; review the relationship between pricing and manufacturer 
patient programs; and reform government program reimbursement methodologies for drugs. For example, the IRA, among other things, (i) directs the 
Secretary of the U.S. Department of Health and Human Services (“HHS”), to negotiate the price of certain high-expenditure, single-source drugs that have 
been on the market for at least 7 years and biologics that have been on the market for at least 11 years covered under Medicare Part B and Medicare Part D, 
and subjects drug manufacturers to civil monetary penalties and a potential excise tax by offering a price that is not equal to or less than the negotiated 
“maximum fair price” under the law (the “Medicare Drug Negotiation Program”), and (ii) imposes rebates under Medicare Part B and Medicare Part D to 
penalize price increases that outpace inflation. These provisions began to effect progressively in fiscal year 2023. On August 15, 2024, HHS announced the 
agreed-upon prices of the first ten drugs that were subject to price negotiations, although the Medicare Drug Price Negotiation Program is currently subject 
to legal challenges. On January 17, 2025, HHS selected fifteen additional drugs covered under Part D for price negotiation in 2025. Each year thereafter 
more Part B and Part D products will become subject to the Medicare Drug Price Negotiation Program. At the state level, legislatures have increasingly 
passed legislation and implemented regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement 
constraints, discounts, and restrictions on certain product access. In some cases, such legislation and regulations have been designed to encourage 
importation from other countries and bulk purchasing.
We cannot predict what healthcare reform initiatives may be adopted in the future, particularly in light of the recent U.S. Presidential and 
Congressional elections. However, we anticipate that Congress, state legislatures, and third-party payors may continue to review and assess alternative 
healthcare delivery and payment systems and may in the future propose and adopt legislation or policy changes or implementations effecting additional 
fundamental changes in the healthcare delivery system. We also expect ongoing legislative and regulatory initiatives to increase pressure on drug pricing.
Manufacturing and Supply
Following the divestiture of our Greater China assets and business operations, we primarily rely on contract development and manufacturing 
organizations (“CDMOs”) to manufacture our drug candidates.
We currently outsource the manufacturing of clinical trial material for our clinical stage projects to leading CDMOs in China such as WuXi Biologics, 
which have established track records for both clinical trial material supply and commercial material supply. We have assembled a seasoned internal and 
external team with deep experience in this area to drive and monitor this process. For contingency planning purposes, we have also established 
relationships with other CDMOs. We expect to continue our outsourcing relationships with contract manufacturers to meet the ongoing needs for the 
development of our drug candidates. We have framework agreements with these external service providers, under which they provide services to us on a 
project-by-project basis. We also monitor the manufacturing activities of clinical trial material at CDMOs to ensure compliance with local and international 
current good manufacturing practice and applicable regulations. Currently, our contract manufacturers obtain raw materials and supplies for the 
manufacturing activities from multiple suppliers who we believe have sufficient capacity to meet our demands. We typically order materials and services 
on a purchase order basis. We also enter into long-term capacity or minimum supply arrangements with them.
Historically, we invested in a manufacturing facility under construction by TJBio Hangzhou and, through our wholly-owned subsidiary, were and still 
remain the largest shareholder of TJBio Hangzhou. In connection with the divestiture of our Greater China assets and business operations, we have 
transferred most of the equity interests we held in TJBio Hangzhou to certain participating shareholders of TJBio Hangzhou in exchange for 
extinguishment of the existing repurchase obligations owed by I-Mab Hong Kong to those shareholders in the amount of approximately $183 million. We 
may seek to contract with TJBio Hangzhou or other manufacturing facilities to manufacture our drug candidates in the future, which could add to our costs.

A.
Operating Results
Overview
We are a U.S.-based, global biotech company, focused on the development of precision immuno-oncology agents for the treatment of cancer. Our 
innovative immuno-oncology pipeline consists of three clinical stage programs, givastomig; uliledlimab; and ragistomig.
Since the commencement of our operations in 2014, we have devoted most of our efforts and financial resources to organizing and staffing our 
operations, formulating business planning, raising capital, establishing our intellectual property portfolio and conducting preclinical and clinical trials of 
our drug candidates. On February 6, 2024, we entered into definitive agreements to divest our Greater China assets and business operations, including our 
rights to the Greater China portfolio, to TJBio Hangzhou for an aggregate consideration of the RMB equivalent of up to $80 million, contingent on the 
achievement of certain future regulatory and sales-based milestone events as well as royalties. After the completion of the divestiture on April 2, 2024, we 
no longer own any rights to the Greater China portfolio.
We have not generated any revenue from the sales of our products, and as a result, we have incurred net losses since the commencement of our 
operations to 2014, with the exception of 2020 during which we generated net income primarily attributable to the revenues recognized in connection with 
the strategic collaboration with AbbVie. In 2024, 2023 and 2022, our net losses were $22.2 million, $207.7 million and $371.1 million, respectively. We do 
not expect to generate product revenue unless and until we obtain marketing approval for and commercialize a drug candidate, however, we cannot assure 
our investors that we will ever generate significant revenue or profits.
Key Factors Affecting Our Results of Operations
Our results of operations, financial condition, and the year-to-year comparability of our financial results have been, and are expected to continue to be, 
principally affected by the below factors:
Research and Development Expenses
Our results of operations are significantly affected by our cost structure, which primarily consists of research and development expenses and 
administrative expenses.
Research and development activities are central to our business model. We believe our ability to successfully develop drug candidates is the primary 
factor affecting our long-term competitiveness, as well as our future growth and development. Developing high-quality drug candidates requires a 
significant investment of resources over a prolonged period of time, and a core part of our strategy is to continue making sustained investments in this area. 
Since our inception, we have focused our resources on our research and development activities, including conducting preclinical studies and clinical trials, 
and activities related to regulatory filings for our drug candidates. Our research and development expenses primarily include the following:
•
costs related to development of our pipeline assets under all stages including preclinical testing or clinical trials;
•
patent license fees and other fees under the licensing, collaboration and development agreements with respect to our in-licensed drug candidates; 
and

Table of Contents
•
employee salaries and related benefit costs, including share-based compensation expenses, for research and development personnel and key 
management.
Our research and development costs may increase period over period as we continue to support and advance the clinical trials of our drug candidates.
Administrative Expenses
Our administrative expenses consist primarily of employee salaries and related benefit costs. Other administrative expenses include service fees for 
legal, intellectual property, consulting and auditing services as well as other direct and allocated expenses such as rent on our facilities, travel costs and 
other supplies used in administrative activities. We expect our near term administrative expenses to decrease in relation to prior years, due to a streamlined 
operating model and reduced legal costs.
Revenue from Out-Licensing Agreements
We continue to seek out-licensing opportunities for our drug candidates through our network of global partnerships and alliances. As we have not 
obtained marketing approval for or commercialized a drug candidate, our revenues at the current stage are primarily subject to the availability of payments 
from granting licenses to research, develop and otherwise exploit certain of our drug candidates, and supply of the investigational products thereof, which 
primarily contributed to our revenues in 2023 and 2022. See “Item 4. Information on the Company—B. Business Overview—Licensing and Collaboration 
Arrangements” for more information on the existing out-licensing arrangements. 
In addition, after validating clinical safety and preliminary efficacy of a drug candidate in our Global portfolio in clinical trials in the United States, 
we may elect to out-license certain rights of such drug candidate, but we may choose to retain these rights for the United States or other countries or regions
as we may deem fit. Before the commercialization of one or more of our drug candidates, we expect that the majority of our revenue will continue to be 
generated from out-licensing our intellectual properties.
Funding for Our Operations
During the periods presented, we funded our operations primarily through public and private placements, as well as revenue from licensing and 
collaboration deals. In the future, in the event of successful commercialization of one or more of our drug candidates, we expect to fund our operations in 
part with revenue generated from sales of our commercialized drug products. However, we believe we will need to raise additional capital to complete the 
development and commercialization of our other drug candidates and in connection with our continuing operations and other planned activities. Such 
funding may take the form of public or private offerings, debt financing, collaborations, licensing arrangements or other sources. Any fluctuation in our 
ability to fund our operations will impact our cash flow plan and our results of operations.
Our Ability to Commercialize Our Drug Candidates
Our business and results of operations depend on our ability to commercialize our drug candidates, once and if those candidates are approved for 
marketing by the applicable health authority. Currently, our pipeline consists of three clinical stage drug candidates. Although we currently do not have any 
product approved for commercial sale and have not generated any revenue from product sales, we expect to generate revenue from sales of our drug 
candidates after we complete the clinical development, obtain regulatory approval, and successfully commercialize such drug candidates, if ever. See “Item 
4. Information on the Company—B. Business Overview—Our Drug Pipeline” for more information on the development status of our various drug 
candidates.
The Effect of Our Acquisition of I-Mab Tianjin and Our Divestiture of the Greater China Assets and Business Operations 
We acquired a controlling interest in I-Mab Tianjin on July 15, 2017 and the remaining interest in I-Mab Tianjin in May 2018. Since our acquisition 
of the controlling interest in I-Mab Tianjin on July 15, 2017, I-Mab Tianjin has been consolidated into our results of operations. Shortly after we acquired 
the controlling interest in I-Mab Tianjin, we integrated the operations of I-Mab Tianjin into our operations. I-Mab Tianjin did not generate any external 
revenue from July 15, 2017 to December 31, 2024. In connection with our acquisition of I-Mab Tianjin, we identified intangible assets of $22.4 million and 
goodwill of $23.0 million of I-Mab Tianjin. Goodwill is not amortized, but impairment of goodwill assessment is performed on at least an annual basis on 
December 31 or whenever events or changes in circumstances indicate that the carrying value of the reporting unit may exceed its fair value. For the year 
ended December 31, 2023, we recognized a goodwill impairment in the amount of $23.0 million against the goodwill balance as of December 31, 2023. 
We did not recognize any goodwill impairment for the year ended December 31, 2022. Impairment charges could substantially affect our results of 
operations in the periods of such charges. In addition, impairment charges would negatively impact our financial ratios and could limit our ability to obtain 
financing in the future.

On February 6, 2024, we entered into definitive agreements to divest our Greater China assets and business operations, including our rights to the 
Greater China portfolio, to TJBio Hangzhou for an aggregate consideration of the RMB equivalent of up to $80 million, contingent on the achievement of 
certain future regulatory and sales-based milestone events as well as royalties. After the completion of the divestiture on April 2, 2024, we do not own any 
rights to the Greater China portfolio, including the Greater China rights for uliledlimab, lemzoparlimab, and givastomig. We no longer bear future 
development costs of our Greater China assets and business operations. 
As a result of our divestiture of our Greater China assets and business operations, we have ceased to consolidate the divested entity, assets and 
businesses as well as its corresponding financial results from the second quarter of 2024 onwards.
Key Components of Results of Operations
The following results of operations relate to continuing operations.
Revenues
We did not generate any revenue for the year ended December 31, 2024. For the years ended December 31, 2023 and 2022, we generated revenue 
from licensing and collaboration arrangements, primarily through granting licenses to use and otherwise exploiting certain of our intellectual properties in 
connection with our drug candidates. The decrease in 2022 net revenue was primarily due to a non-cash adjustment of $(5.8) million recorded in the second 
half of 2022 following the amendment to the original license and collaboration agreement with AbbVie in August 2022.
Research and Development Expenses
Research and development expenses primarily consist of: (i) payroll and other related expenses of personnel engaged in research and development 
activities, (ii) fees associated with the exclusive development rights of our in-licensed drug candidates, (iii) fees for services provided by CROs, 
investigators and clinical trial sites that conduct our clinical studies, and (iv) expenses relating to the development of our drug candidates, including raw 
materials and supplies, product testing, depreciation, and facility related expenses, and (v) other research and development expenses. 
Following the completion of the divestiture of our Greater China assets and business operations on April 2, 2024, our current research and 
development activities primarily relate to the clinical development of the following investigational drugs:
•
Givastomig, a bispecific antibody targeting CLDN18.2-positive tumor cells, that conditionally activates T cells via 4-1BB in the tumor
microenvironment, with potential CLDN18.2 specificity even in tumors with low levels of CLDN18.2 expression;
•
Uliledlimab, a monoclonal antibody designed to target CD73, the rate-limiting enzyme critical for adenosine-driven immunosuppression in the 
tumor microenvironment; and
•
Ragistomig, a bispecific, Fc-silent, antibody designed to provide anti-PD-L1 activity and conditional 4-1BB-driven T-cell activation in the tumor 
microenvironment.
We incurred research and development expenses of $21.8 million, $21.4 million and $22.5 million for the years ended December 31, 2024, 2023 and 
2022, respectively, representing 42.3%, 43.2% and 43.8% of our total research and development and administrative expenses for the corresponding periods. 
Our research and development costs may increase period over period as we continue to support and advance the clinical trials of our drug candidates.
Administrative Expense
Administrative expenses primarily consist of salaries and related benefit costs, including share-based compensation, for employees engaged in 
managerial and administrative positions or involved in general corporate functions, professional fees for consulting and auditing as well as other direct and 
allocated expenses such as rent on our facilities, travel costs and other supplies used in administrative activities. For the years ended December 31, 2024, 
2023 and 2022, our administrative expenses amounted to $29.7 million, $28.2 million and $29.0 million, respectively. We expect our near term 
administrative expenses to decrease in relation to prior years, due to a streamlined operating model and reduced legal costs.

Interest Income
Interest income consists primarily of interest income derived from our term deposits.
Other Income (Expenses), Net
Other income (expenses), net consists primarily of the settlement of TJ Biopharma repurchase obligations, fair value changes of put right liabilities, 
net foreign exchange gains (losses), asset impairment loss, incentive payments from our ADS depository bank, rent expenses and sublease income.
Equity In Loss of Affiliates
Equity in loss of affiliates consists primarily of the loss recognized based on our proportionate ownership in TJBio Hangzhou, our unconsolidated 
investee prior to the equity transfer of our interests in TJBio Hangzhou to certain participating shareholders of TJBio Hangzhou. 
Taxation
Cayman Islands
I-Mab, our holding entity, is incorporated in the Cayman Islands. According to Harney Westwood & Riegels, our Cayman Islands counsel, the 
Cayman Islands currently levies no taxes on individuals or corporations based upon profits, income, gains or appreciation and there is no taxation in the 
nature of inheritance tax or estate duty. There are no other taxes likely to be material to us levied by the Government of the Cayman Islands, except for 
stamp duties, which may be applicable on instruments executed in, or brought to, or produced before a court of the Cayman Islands. The Cayman Islands is 
not a party to any double tax treaties that are applicable to any payments made to or by our company. There are no exchange control regulations or currency 
restrictions in the Cayman Islands.
Hong Kong
I-Mab, our holding entity, holds a business registration and tax file number in Hong Kong. I-Mab Biopharma Hong Kong Limited is incorporated in
Hong Kong. Companies registered in Hong Kong are subject to Hong Kong profits tax on the taxable income as reported in their respective statutory 
financial statements adjusted in accordance with the Hong Kong tax laws. Under the current Hong Kong Inland Revenue Ordinance, from the year of 
assessment 2018/2019 onwards, companies registered in Hong Kong are subject to profits tax at the rate of 8.25% on assessable profits up to 
HK$2,000,000; and 16.5% on any part of assessable profits over HK$2,000,000. For the year ended December 31, 2022, I-Mab recorded income tax 
expense of $0.1 million in the consolidated statements of comprehensive loss. I-Mab did not record any income tax expense for the years ended December 
31, 2024 and 2023. For the years ended December 31, 2024, 2023 and 2022, I-Mab Biopharma Hong Kong Limited did not make any provisions for Hong 
Kong profit tax as there were no assessable profits derived from or earnings in Hong Kong for any of the periods presented. Under the Hong Kong tax law, 
I-Mab and I-Mab Biopharma Hong Kong Limited are exempted from income tax on its foreign-derived income and there are no withholding taxes in Hong 
Kong on remittance of dividends.
United States
I-Mab Biopharma US Ltd. is incorporated in Maryland and is subject to U.S. federal corporate income tax at a rate of 21%. It is also subject to state 
income tax in Maryland and several other states at a blended rate of 3.63%. I-Mab Biopharma US Ltd. has no taxable income for all periods presented and 
therefore no provision for income taxes is required.
China
I-Mab Tianjin is incorporated in the PRC and is subject to PRC income tax at a rate of 25%. I-Mab Biopharma US Ltd. has no taxable income for all 
periods presented, therefore, no provision for income taxes is required.
A valuation allowance is provided to reduce the amount of deferred tax assets if it is considered more likely than not that some portion or all of the 
deferred tax assets will not be realized in the foreseeable future. In making such determination, we evaluate a variety of positive and negative factors 
including our operating history, accumulated deficit, the existence of taxable temporary differences and reversal periods.

Table of Contents
We have incurred net accumulated operating losses for income tax purposes since our inception. We believe that it is more likely than not that these 
net accumulated operating losses will not be utilized in the future based on the assessment as of December 31, 2024. Therefore, we have provided full 
valuation allowances for the deferred tax assets as of December 31, 2024, 2023 and 2022. 
We evaluate each uncertain tax position (including the potential application of interest and penalties) based on the technical merits, and measure the 
unrecognized benefits associated with the tax positions. As of December 31, 2024, 2023 and 2022, we did not have any significant unrecognized uncertain 
tax positions.

Year Ended December 31, 2024 Compared to Year Ended December 31, 2023 
Revenues
We did not generate any revenue for the year ended December 31, 2024, compared with revenue of $0.6 million for the year ended December 31, 
2023. Total revenue for the year ended December 31, 2023 was recognized in connection with the strategic collaboration with AbbVie.

Our research and development expenses increased by $0.3 million, or 1.5%, from $21.4 million for the year ended December 31, 2023 to $21.8 
million for the year ended December 31, 2024, primarily attributable to an increase in givastomig-related spending, partially offset by a decrease of $1.9 
million in employee-related expenses due to lower headcount and a decline in stock price.
Administrative Expenses
Our administrative expenses increased by $1.5 million, or 5.3%, from $28.2 million for the year ended December 31, 2023 to $29.7 million for the 
year ended December 31, 2024, primarily attributable to an increase in professional services fees of $13.8 million due to an increase in legal expenses 
associated with certain trade secret misappropriation disputes against Inhibrx, Inc. This increase was partially offset by a decrease in employee-related 
expenses of $12.4 million due to the forfeiture of shares as a result of the divestiture of our Greater China assets and business operations and a decline in 
stock price, as well as exits of certain executive employees.
Interest Income
We recorded interest income of $7.5 million and $9.3 million for the years ended December 31, 2024 and 2023, respectively. The decrease for the 
year ended December 31, 2024 was primarily attributable to lower average investable cash balances.
Other Income (Expenses), Net
We recorded other expenses of $4.7 million and $8.1 million for the years ended December 31, 2024 and 2023, respectively. The change was 
primarily attributable to the fair value changes and extinguishment of put right liabilities and a smaller impact from foreign exchange losses, partially offset 
by expenses recognized on the settlement of TJ Biopharma repurchase obligations and fixed asset impairments. 
Equity in Loss of Affiliates
We recorded equity in loss of affiliates of $1.0 million and $11.4 million for the years ended December 31, 2024 and 2023, respectively. The decrease
was driven by no further recognition of allocated losses from our unconsolidated investee, as the investee no longer qualified for equity method accounting 
after the first quarter of 2023 and a decline in employee stock ownership plan expenses through the first quarter of 2024 prior to the transfer of our shares in
the unconsolidated investee to certain participating shareholders in connection with the divestiture of our Greater China assets and business operations.

Year Ended December 31, 2023 Compared to Year Ended December 31, 2022 
Revenues
Total net revenues for the year ended December 31, 2023 were $0.6 million, compared with $(1.6) million for the year ended December 31, 2022. The 
change in 2023 net revenue was primarily due to a non-cash adjustment of $(5.8) million recorded in the second half of 2022 following the amendment to 
the original license and collaboration agreement with AbbVie in August 2022. This amendment led to a lowered probability of achieving a key milestone 
that was included in the total consideration of revenue recognition in prior years. The decrease was partially offset by revenue of $4.3 million from license 
and collaboration arrangements with AbbVie and Ferring. See Note 12 – Licensing and collaboration arrangements of our consolidated financial 
statements included elsewhere in this annual report for additional information on these collaboration arrangements.

million for the year ended December 31, 2023, primarily attributable to a decrease of $2.2 million in CRO service fees driven by lower uliledlimab-related 
and lemzoparlimab-related fees and a decrease of $1.3 million in employee-related expenses due to both lower headcount and a decline in stock price. The 
decrease was partially offset by an increase in givastomig-related spending. 
Administrative Expenses
Our administrative expenses decreased by $0.8 million, or 2.8%, from $29.0 million for the year ended December 31, 2022 to $28.2 million for the 
year ended December 31, 2023, primarily attributable to the decrease in employee-related expenses of $1.6 million driven by a decline in stock price, 
partially offset by an increase in professional services fees of $1.1 million due to an increase in legal expenses associated with certain trade secret 
misappropriation disputes against Inhibrx, Inc.
Impairment of Goodwill
We recognized an impairment of goodwill of $23.0 million for the year ended December 31, 2023, primarily attributable to the termination of a 
licensing and collaboration agreement with AbbVie in the fourth quarter of 2023. The goodwill impairment was a result of our annual impairment analysis.
Interest Income
We recorded interest income of $9.3 million and $5.0 million for the years ended December 31, 2023 and 2022, respectively. The increase for the year 
ended December 31, 2023 was primarily attributable to the increase in interest rates on our bank deposits held in U.S. dollars.
Other Income (Expenses), Net
We recorded other expenses of $8.1 million and $28.3 million for the years ended December 31, 2023 and 2022, respectively. The decrease in other 
expenses for the year ended December 31, 2023 was primarily attributable to a smaller impact from foreign exchange losses for the year ended December 
31, 2023, partially offset by the fair value change of put right liabilities.
Equity in Loss of Affiliates
We recorded equity in loss of affiliates of $11.4 million and $64.7 million for the years ended December 31, 2023 and 2022, respectively. The change 
was mainly due to the operating loss of our unconsolidated investee, TJBio Hangzhou.

Critical Accounting Policies and Significant Judgments and Estimates 
Our reported results are impacted by the application of certain accounting policies that require us to make subjective or complex judgments. These 
judgments involve estimations of the effect of matters that are inherently uncertain and may significantly impact our quarterly or annual results of 
operations or financial condition. Changes in the estimates and judgments could significantly affect our results of operations, financial condition and cash 
flows in future years. A description of what we consider to be our most significant critical accounting policies and estimates follows.
Revenue Recognition
We adopted Accounting Standard Codification 606, Revenue from Contracts with Customers (Topic 606) (the “ASC 606”) for all periods presented. 
Consistent with the criteria of Topic 606, we recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects 
the consideration to which the entity expects to receive in exchange for those goods or services.
Under ASC 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the 
consideration that the entity expects to receive in exchange for those goods or services. The entity performs the following five steps to account for the 
arrangements that an entity determines are within the scope of ASC 606: (i) identify the contract(s) with a customer; (ii) identify the performance 
obligations in the contract; (iii) determine the transaction price, including variable consideration, if any; (iv) allocate the transaction price to the 
performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation.
Once a contract is determined to be within the scope of ASC 606 at contract inception, we evaluate the contract to determine which performance 
obligations it must deliver and which of these performance obligations are distinct. We recognize as revenue the amount of the transaction price that is 
allocated to each performance obligation when that performance obligation is satisfied or as it is satisfied.
Variable consideration in collaboration revenue arrangements
If the consideration promised in a contract includes a variable amount, we will estimate the amount of consideration to which we will be entitled in 
exchange for transferring the promised goods or services to a customer. An amount of consideration can vary because of discounts, rebates, refunds, 
credits, price concessions, incentives, performance bonuses, penalties, or other similar items. The promised consideration also can vary if an entity’s 
entitlement to the consideration is contingent on the occurrence or nonoccurrence of a future event. We estimate an amount of variable consideration by 
using either of the following methods, depending on which method we expect to better predict the amount of consideration to which it will be entitled:
a.
The expected value—The expected value is the sum of probability-weighted amounts in a range of possible consideration amounts. An expected
value may be an appropriate estimate of the amount of variable consideration if an entity has a large number of contracts with similar 
characteristics.
b.
The most likely amount—The most likely amount is the single most likely amount in a range of possible consideration amounts (that is, the 
single most likely outcome of the contract). The most likely amount may be an appropriate estimate of the amount of variable consideration if the 
contract has only two possible outcomes (for example, an entity either achieves a performance bonus or does not).
We include in the transaction price some or all of an amount of variable consideration estimated in accordance with above only to the extent that it is 
probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable 
consideration is subsequently resolved.
Determination of the standalone selling price of each performance obligation
Our collaborative arrangements may contain more than one unit of account, or performance obligation, including grants of licenses to intellectual 
property rights, agreement to provide research and development services and other deliverables. The collaborative arrangements do not include a right of 
return for any deliverable. As part of the accounting for these arrangements, we must develop assumptions that require judgment to determine the 
standalone selling price for each performance obligation identified in the contract. In developing the stand-alone selling price for a performance obligation, 
we consider competitor pricing for a similar or identical product, market awareness of and perception of the product, expected product life and current 
market trends. In general, the consideration allocated to each performance obligation is recognized when the respective obligation is satisfied either by 
delivering a good or providing a service, limited to the consideration that is not constrained.

Cost-to-cost measure of progress for over time performance obligations
Under our certain licensing and collaboration arrangement entered into with a business partner, we recognized revenue using the cost-to-cost measure. 
Under the cost-to-cost measure of progress method, the extent of progress towards completion is measured based on the ratio of costs incurred to-date to 
the total estimated costs for completion of the performance obligations. We generally use a cost-to-cost measure of progress because it best depicts the 
transfer of benefits to a licensee. We applied significant judgment in estimating the total costs for completion of performance obligations under such 
licensing and collaboration arrangement.
See Note 12 – Licensing and collaboration arrangements of our consolidated financial statements included elsewhere in this annual report for a 
further discussion of our licensing and collaboration revenues.
Investments in available-for-sale debt securities
Investments in available-for-sale debt securities are accounted for at fair value. We determine the fair value of our investments with the assistance of 
an independent third-party valuation firm. We utilized a backsolved methodology to determine the estimated equity value of the investee and subsequently 
adjust this value as of each reporting period by applying a change in the movement of a selected set of comparable companies and biotech indices. This 
value was then allocated towards the different preferred share classes of the investment using an option pricing method (“OPM”) and a waterfall approach 
based on the order of liquidation preferences of the share classes relative to one another. The significant assumptions of the OPM include equity market 
adjustment, expected time to change in control in years, estimated volatility and a risk-free rate based on the Chinese sovereign yield curve. 
The unrealized gains and losses of the investment in available-for-sale debt securities are included as a component of accumulated other 
comprehensive income. For investments in an unrealized loss position, we assess whether we intend to sell the security or will more likely than not be 
required to sell the security before recovery of the security’s amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the 
security's amortized cost basis is written down to fair value and the impairment is recognized in other income (expense), net in the consolidated statements 
of comprehensive loss. If the security does not meet the aforementioned intent or requirement to sell criteria, we evaluate whether the decline in fair value 
is due to credit-related factors. Any impairment due to credit-related losses are recorded as an allowance for credit losses and are included in other income 
(expense), net in the consolidated statements of comprehensive loss.
Fair value measurement of put right liabilities
A put right written by us to third party investors in our affiliate was recorded as a freestanding equity-linked instrument and classified as a put right 
liability. We determined the fair value of the put right with the assistance of an independent third-party valuation firm. We used the option pricing model 
(Finnerty model) to estimate the fair value of the put right. The model requires the input of key assumptions including the expected terms, estimated 
volatility, spot price and probability of triggering event for redemption option. The significant unobservable inputs used in the option pricing model 
included spot price, estimated volatility and probability of triggering event for redemption option. The expected term is estimated based on the timing of a 
hypothetical redemption event which is assumed to be the earlier of expected redemption date or expected public offering date. Expected volatility is 
estimated based on daily stock prices of the comparable companies for a period with length commensurate to the expected terms of redemption event. The 
spot price was determined using the income approach with assistance from an independent third-party valuation firm. The significant unobservable inputs 
used in the income approach include revenue growth rates and discount rates.
Research and Development Expenses
Elements of research and development expenses primarily include (i) payroll and other related expenses of personnel engaged in research and 
development activities, (ii) fees associated with the exclusive development rights of our in-licensed drug candidates, (iii) fees for services provided by 
CROs, investigators and clinical trial sites that conduct our clinical studies, (iv) expenses relating to the development of our drug candidates, including raw 
materials and supplies, product testing, depreciation, and facility related expenses, and (v) other research and development expenses. Research and 
development expenses are recognized in expenses as incurred when these expenditures are used for the Group’s research and development activities and 
have no alternative future uses.
We applied significant judgment in estimating the progress of our research and development activities and completion of or likelihood of achieving 
milestone events per underlying agreements when estimating the research and development costs to be accrued at each reporting period end. The process of 
estimating our research and development expenses involves reviewing open contracts and purchase orders, communicating with personnel to identify 
services that have been performed on our behalf and estimating the level of service performed and the associated costs incurred for the services when we 
have not yet been invoiced or otherwise notified of the actual costs.

Goodwill
Goodwill is an asset representing the future economic benefits arising from other assets acquired in a business combination that are not individually 
identified and separately recognized. We allocate the cost of an acquired entity to the assets acquired and liabilities assumed based on their estimated fair 
values at the date of acquisition. The excess of the purchase price for acquisitions over the fair value of the net assets acquired, including other intangible 
assets, is recorded as goodwill. Goodwill is not amortized, but impairment of goodwill is tested on at least an annual basis or whenever events or changes in 
circumstances indicate that the carrying value of the reporting unit exceeds its fair value.
We first assess qualitative factors to determine whether it is more likely than not that the fair value of our reporting unit is less than its carrying 
amount, including goodwill. The qualitative assessment includes our evaluation of relevant events and circumstances affecting our single reporting unit, 
including macroeconomic, industry, market conditions and our overall financial performance. If qualitative factors indicate that it is more likely than not 
that our reporting unit’s fair value is less than its carrying amount, then we will perform the quantitative impairment test by comparing the reporting unit’s 
carrying amount, including goodwill, to its fair value. If the carrying amount of the reporting unit exceeds its fair value, an impairment loss will be 
recognized in an amount equal to that excess.
We applied significant judgment in developing the fair value of our single reporting unit. Fair value of the reporting unit is estimated by us using a 
discounted cash flow model which requires us to make judgments and assumptions related to future revenues, discount rate and terminal growth rate. The 
probabilities of the success of the clinical trials based on the status of these trials and reference to the industry benchmark were also incorporated into the 
assumption of future revenues.

Liquidity and Capital Resources
Cash Flows and Working Capital 
We have incurred net losses and negative cash flows from our operations for the years ended December 31, 2024, 2023 and 2022. Substantially all of 
our losses have resulted from funding our research and development programs and administrative costs associated with our operations. We incurred net 
losses from continuing operations of $49.7 million, $82.2 million and $141.2 million for the years ended December 31, 2024, 2023 and 2022, respectively. 
Our primary use of cash is to fund our research and development activities. We used $52.7 million, $72.7 million and $49.6 million in cash for our 
operating activities for the year ended December 31, 2024, 2023 and 2022, respectively. As of December 31, 2024, we had cash and cash equivalents of 
$68.3 million and short-term investments of $105.1 million. Our cash and cash equivalents consist primarily of cash held in banks and short term securities. 
Historically, we have financed our operations primarily through public and private placements, as well as revenue from licensing and collaboration deals. 
We may need to raise additional capital through various potential sources, such as equity and/or debt financings, strategic relationships, potential strategic 
transactions or out-licensing of our products. 
The following table sets forth a summary of our cash flows for the periods presented:

We do not expect to generate any revenue from the sales of our products unless and until we obtain regulatory approval of and commercialize one of 
our current or future drug candidates. We anticipate that we will continue to generate losses for the foreseeable

Table of Contents
future, and we expect the losses to increase as we continue the development of, and seek regulatory approvals for, our drug candidates and begin to 
commercialize any approved products. In addition, subject to obtaining regulatory approval of any of our drug candidates, we expect to incur significant
commercialization expenses for product sales, marketing and manufacturing. Accordingly, we anticipate that we will need substantial additional funding in 
connection with our continuing operations.
Based on our current operating plan, we believe that our current cash, cash equivalents and short-term investments of $173.4 million will be sufficient 
to meet our current and anticipated working capital requirements and capital expenditures for at least the next 12 months. We have based our estimates on 
assumptions that may prove to be wrong, and we may use our available capital resources sooner than we currently expect. Because of the numerous risks 
and uncertainties associated with the development and commercialization of our drug candidates, we are unable to estimate the amounts of increased 
capital outlays and operating expenditures necessary to complete the development and commercialization of our drug candidates.
We may decide to enhance our liquidity position or increase our cash reserve for future operations and investments through additional financing. The 
issuance and sale of additional equity would result in further dilution to our shareholders and ADS holders, and the terms of these securities may include 
liquidation or other preferences that adversely affect our investors’ rights as ADS holders. The incurrence of indebtedness would result in increased fixed 
or variable obligations and could result in operating covenants that would restrict our operations, which could potentially dilute the interests of our 
shareholders. If we raise additional funds through collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish 
valuable rights to our technologies, future revenue streams or research programs or to grant licenses on terms that may not be favorable to us. If we are 
unable to raise additional funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our product 
development or future commercialization efforts or grant rights to develop and market products or drug candidates that we would otherwise prefer to 
develop and market ourselves.
As of December 31, 2024, approximately one percent of our cash and cash equivalents were denominated in RMB and held in China. The majority of 
our cash and cash equivalents is denominated in U.S. dollars and held in the United States. We also expect that the majority of any future revenues and
additional fund raising will be denominated in U.S. dollars to support our future working capital requirements and capital expenditures. However, some 
events that are beyond our control may materially and adversely affect our ability to raise additional capital in future and our liquidity. See “Item 3. Key 
Information—D. Risk Factors—Risks Related to Our Industry, Business and Operations—Our business and results of operations could be adversely 
affected by public health crisis and natural catastrophes or other disasters outside of our control in the locations in which we, our suppliers, CROs, contract 
manufacturing organizations and other contractors operate.”
Operating Activities
Net cash used in operating activities from continuing operations for the year ended December 31, 2024 was $52.7 million. Our net loss was $49.7 
million for the same period. The difference between our net loss and our net cash used in operating activities was primarily attributable to certain non-cash 
benefits, including the change in fair value and extinguishment of put right liabilities of $13.9 million and share-based compensation of $1.9 million, 
partially offset by the settlement of TJ Biopharma repurchase obligations expense of $12.4 million.
Net cash used in operating activities from continuing operations for the year ended December 31, 2023 was $72.7 million. Our net loss was $82.2 
million for the same period. The difference between our net loss and our net cash used in operating activities was primarily attributable to certain non-cash 
expenses, including share-based compensation of $10.2 million, impairment of goodwill of $23.0 million and equity in loss of affiliates of $11.4 million, 
partially offset by changes in certain working capital items, including a decrease in accruals and other payables of $35.7 million.
Net cash used in operating activities from continuing operations for the year ended December 31, 2022 was $49.6 million. Our net loss was $141.2 
million for the same period. The difference between our net loss and our net cash used in operating activities was primarily attributable to certain non-cash 
expenses, including equity in loss of affiliates of $64.7 million and share-based compensation of $13.1 million and changes in certain working capital
items, including an increase in accruals and other payables of $18.3 million.
Investing Activities
Net cash used in investing activities from continuing operations for the year ended December 31, 2024 was $136.0 million. The net cash decrease was 
primarily attributable to $194.7 million of cash used in the purchase of short-term and other investments and $51.1 million of cash used in the purchase of 
available-for-sale debt securities partially offset by proceeds from disposal of short-term and other investments of $109.8 million.

 
103
Table of Contents
Net cash used in investing activities from continuing operations for the year ended December 31, 2023 was $15.2 million. The net cash decrease was 
primarily attributable to $100.0 million of cash used in the purchase of short-term and other investments partially offset by proceeds from disposal of short-
term and other investments of $85.0 million.
Net cash used in investing activities from continuing operations for the year ended December 31, 2022 was $5.2 million. The net cash decrease was 
primarily attributable to $767.5 million of cash used in the purchase of short-term and other investments partially offset by proceeds from disposal of short-
term and other investments of $764.4 million.
Financing Activities
Net cash used in financing activities for the year ended December 31, 2024 was $0.3 million, attributable to payment for stock repurchases during the 
year.
Net cash used in financing activities for the year ended December 31, 2023 was $8.2 million, primarily attributable to $8.6 million used in the 
payment for stock repurchases during the year, partially offset by $0.4 million of proceeds from exercise of stock options.
Net cash generated from financing activities for the year ended December 31, 2022 was $3.9 million, attributable to the proceeds from exercise of
stock options of $6.9 million, partially offset by $3.0 million used in the payment for stock repurchases. 
Material Cash Requirements 
Contractual Obligation
Our material cash requirements as of December 31, 2024 and any subsequent interim period primarily include our operating lease obligations.
Our capital expenditures were incurred for purposes of purchasing property, equipment and software. Our capital expenditures were less than $0.1 
million for the year ended December 31, 2024, and $0.2 million and $2.1 million for the years ended December 31, 2023 and 2022, respectively.
Our operating lease commitments range from approximately 3 to 6 years lease terms, with a total commitment amount of $4.4 million as of December 
31, 2024. 
Other than those disclosed above, we did not have any significant capital and other commitments, long-term obligations or guarantees as of December 
31, 2024.
We entered into certain unconditional purchase obligations and other commitments in the normal course of business. There have been no changes to 
these commitments that would have a material impact on our ability to meet either short-term or long-term future cash requirements.
We have not entered into any financial guarantees or other commitments to guarantee the payment obligations of any third parties. In addition, we 
have not entered into any derivative contracts that are indexed to our shares and classified as shareholder’s equity or that are not reflected in our 
consolidated financial statements. Furthermore, we do not have any retained or contingent interest in assets transferred to an unconsolidated entity that 
serves as credit, liquidity or market risk support to such entity. We do not have any variable interest in any unconsolidated entity that provides financing, 
liquidity, market risk or credit support to us or engages in leasing, hedging or product development services with us.
Collaborations, Licensing and Other Arrangements
We entered into collaborative, licensing, and other arrangements with third parties that may require future milestone payments to third parties 
contingent upon the achievement of certain development, regulatory, or commercial milestones. Individually, these arrangements are insignificant in any 
one annual reporting period. However, if milestones for multiple products covered by these arrangements would happen to be reached in the same reporting 
period, the aggregate charge to expense could be material to the results of operations in that period. From a business perspective, the payments are viewed 
as positive because they signify that the product is successfully moving through development and is now generating or is more likely to generate future 
cash flows from product sales. It is not possible to predict with reasonable certainty whether these milestones will be achieved or the timing for 
achievement. See Note 12 – Licensing and collaboration arrangements of our consolidated financial statements included elsewhere in this annual report for 
additional information on these collaboration arrangements.

Holding Company Structure
We are a holding company with no material operations of its own. Following the divestiture of our Greater China assets and business operations, we 
currently conduct our operations primarily through our subsidiary in the United States and only a small portion of business operations in China through our 
PRC subsidiary. As a result, our ability to pay dividends depends upon dividends paid by our U.S. and PRC subsidiaries. In the event that we may rely on 
dividends paid by our PRC subsidiary, there are certain limitations imposed by debt instruments or PRC laws, rules and regulations. For details, see “Item 
4. Information on the Company—B. Business Overview—Regulation—PRC Regulation—Regulations Relating to Foreign Exchange and the Dividend 
Distribution” and “Item 3. Key information—D. Risk Factors—General Risks Related to Our ADSs—Because we do not expect to pay dividends in the 
foreseeable future, our investors must rely on price appreciation of our ADSs for return on their investment.”

Compensation.
For the fiscal year ended December 31, 2024, we paid an aggregate of approximately $3.7 million for salaries and benefits in cash to our current and 
former executive officers, and an aggregate of approximately $0.6 million for compensation in cash to our independent directors. We did not pay any 
compensation to our directors who are not our independent directors or executive officers. In addition, during the fiscal year ended December 31, 2024 we 
paid approximately $231 thousand to ABio-X Holdings, Inc. (“ABio-X”) pursuant to the terms of a secondment agreement (the “Secondment Agreement”) 
between I-MAB US and ABio-X, pursuant to which Dr. Fu was seconded by ABio-X to I-MAB US and its affiliates, including the Company (the “I-Mab 
Group”), to serve as Interim CEO of the I-Mab Group on a substantially full-time basis. See “Item 7. Major Shareholders and Related Party Transactions – 
Related Party Transactions – Secondment Agreement” for additional information. We have not set aside or accrued any amount to provide pension, 
retirement or other similar benefits to our executive officers and directors. Our PRC subsidiary is required by law to make contributions equal to certain 
percentages of each employee’s salary for his or her pension insurance, medical insurance, unemployment insurance and other statutory benefits and a 
housing provident fund.
Employment Agreements and Indemnification Agreements
We have entered into an employment agreement with our Chief Executive Officer and offer letters with each of our other executive officers. These 
agreements provide for base salaries and incentive compensation, and each component reflects the scope of each executive officer’s anticipated 
responsibilities and the individual experience they bring to the company.
We have also entered into indemnification agreements with each of our directors and executive officers. Under these agreements, we agree 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 a director or officer of our company.
Director Compensation
Each member of the board of directors who is not an employee of the Company is eligible to receive cash and equity compensation pursuant to a Non-
Employee Director Compensation Policy (the ‘Director Compensation Policy’).
Cash Compensation
Pursuant to the Director Compensation Policy, each non-employee director receives an annual cash retainer of $45,000; the chairperson receives an 
additional $35,000 per year. In addition, the chair of the Audit Committee, the Chair of the Compensation Committee and the Chair of the Nominating and 
Corporate Governance Committee receive an additional cash retainer of $20,000, $15,000 and $10,000, respectively, each year. The members of the Audit 
Committee, the Compensation Committee and the Nominating and Corporate Governance Committee receive an additional cash retainer $10,000, $7,500 
and $5,000, respectively, each year, however, in each case such cash retainer is payable only to members who are not the chairperson of such committee.
Equity Compensation
In addition to the cash compensation structure described above, the Director Compensation Policy provides for the following equity incentive 
compensation program for non-employee directors. 
Initial Grant. Each non-employee director who joins our board of directors will automatically, be granted a one-time, initial stock option to purchase 
shares equal to the number of Ordinary Share Equivalents that results in the aggregate grant date fair value of the option award pursuant to ASC Topic 718 
being equal to $75,000 (each, an “Initial Option Award”) and a restricted share unit award equal to the number of ADSs that results in the aggregate grant 
date fair value of the option award pursuant to ASC Topic 718 being equal to $75,000 (each an “Initial RSU Award”). The shares subject to each Initial 
Option Award will vest in equal annual installments over a three year period such that the Initial Option Award is fully vested on the third anniversary of 
the date of grant, subject to the non-employee director’s continuous service through each such vesting date and will vest in full upon certain changes in 
control. The shares subject to each Initial RSU Award will vest in equal annual installments over a three year period such that the Initial RSU Award is 
fully vested on the third anniversary of the date of grant, subject to the non-employee director’s continuous service, and will vest in full upon certain 
changes in control.

Share Incentive Plans
Second Amended and Restated 2017 Employee Stock Option Plan
In October 2017, we adopted an equity incentive plan (as last amended and restated in December 2019), which we refer to as the 2017 Plan, to secure 
and retain the services of valuable employees, directors or consultants, and provide incentives for such persons to exert their best efforts for the success of 
our business. The maximum aggregate number of ordinary shares which may be issued pursuant to all awards under the 2017 Plan is 9,609,084, subject to 
certain adjustments. As of March 19, 2025, options to purchase an aggregate of 291,042 ordinary shares under the 2017 Plan had been granted and 
remained outstanding, excluding options that were forfeited, cancelled or exercised after the grant date. No additional shares may be issued under the 2017 
plan.
The following paragraphs describe the principal terms of the 2017 Plan.
Types of awards. The 2017 Plan permits the awards of options.
Plan administration. Our board of directors administers the 2017 Plan. The board of directors determines, among other things, the participants to 
receive options, the number and subscription price of options to be granted to each participant, and the terms and conditions of each option granted.
Offer letter. Options granted under the 2017 Plan are evidenced by an offer letter that sets forth terms, conditions and limitations for each option, 
which may include the term of the option, and the provisions applicable in the event that the grantee’s employment or service terminates.
Eligible participants. We may grant awards to employees, officers, directors, contractors, advisors and consultants of our company.
Vesting schedule. Unless otherwise approved by the board of directors and set forth in an offer letter, the vesting schedule is a three-year vesting 
schedule consisting of a cliff vesting 50% on the second anniversary of the applicable vesting commencement date, and a vesting of the remaining 50% on 
the third anniversary of the applicable vesting commencement date. Except as otherwise approved by the board of directors, vested portion of option 
becomes exercisable upon the earlier of a listing or the occurrence of a change in control.
Exercise of options. The board of directors determines the subscription price for each option, which is stated in the offer letter. The vested portion of 
each option will expire if not exercised prior to the time as the board of directors determines at the time of its grant. However, the maximum exercisable 
term is ten years from the applicable vesting commencement date or such shorter period specified in the award agreement. Further, an option will lapse 
upon the earliest of, among other circumstances, two years after the date when the option becomes exercisable upon the listing or the occurrence of a 
change in control, and a violation in transfer restrictions.
Transfer restrictions. Options may not be transferred in any manner by the participant other than in accordance with the exceptions provided in the 
2017 Plan or the offer letter or otherwise determined by the board of directors, such as transfers by will or the laws of descent and distribution.
Termination and amendment of the 2017 Plan. Unless terminated earlier, the 2017 Plan has a term of ten years. The board of directors has the 
authority to amend, suspend or terminate the plan, subject to the limitations of applicable laws. No amendment, suspension or termination may adversely

second anniversary of the applicable vesting commencement date. Notwithstanding the foregoing, if a listing occurs at any time prior to any option granted 
under the 2018 Plan becoming full vested, and to the extent such option has been granted and outstanding, any such option will vest in full with immediate 
effect upon the listing. Except as otherwise approved by the board of directors, vested portion of option becomes exercisable upon the earlier of six months 
after a listing or the occurrence of a change in control; provided, however that in each case, no option of an employee will become exercisable until the 
third anniversary of such employee’s employment commencement date.

Board Practices
As of the date of this annual report, our board of directors consists of five directors. A director is not required to hold any shares in our company by 
way of qualification. Subject to the Nasdaq Global Market rules and disqualification by the chairman of the board meeting, a director may vote with respect 
to any contract, proposed contract or arrangement in which he or she is interested. A director who is interested in a contract, proposed contract or 
arrangement should declare the nature of his or her interest at the earliest meeting of the board at which it is practicable for him or her to do so, either 
specifically or by way of a general notice. The directors may exercise all the powers of our company to borrow money, mortgage its undertaking, property 
and uncalled capital, and issue debentures or other securities whenever money is borrowed or as security for any obligation of our company or of any third 
party. None of our directors who are not our executive officers has a service contract with us that provides for benefits upon termination of service.
Committees of the Board of Directors
We have established four committees under the board of directors: an audit committee, a compensation committee, a nominating and corporate 
governance committee, and an environmental, social and governance (ESG) committee. We have adopted a charter for each of the four committees. Each 
committee’s members and functions are described below.
Audit Committee. Our audit committee consists of Mr. Conor Chia-hung Yang, Mr. Chun Kwok Alan Au and Mr. Lielie Zhang. Mr. Conor Chia-hung 
Yang is the chairperson of our audit committee. We have determined that each of Mr. Conor Chia-hung Yang, Mr. Chun Kwok Alan Au, and Mr. Lielie 
Zhang satisfies the “independence” requirements of Rule 5605(c)(2) of the Nasdaq Stock Market Rules and meets the independence standards under Rule 
10A-3 under the Exchange Act. We have determined that Mr. Conor

Chia-hung Yang qualifies as an “audit committee financial expert.” The audit committee oversees our accounting and financial reporting processes and the 
audits of the financial statements of our company. The audit committee is responsible for, among other things:
•
appointing the independent auditors and pre-approving all auditing and non-auditing services permitted to be performed by the independent 
auditors;
•
reviewing with the independent auditors any audit problems or difficulties and management’s response;
•
discussing the annual audited financial statements with management and the independent auditors;
•
reviewing the adequacy and effectiveness of our accounting and internal control policies and procedures and any steps taken to monitor and 
control major financial risk exposures;
•
reviewing and approving all proposed related party transactions;
•
meeting separately and periodically with management and the independent auditors; and
•
monitoring compliance with our code of business conduct and ethics, including reviewing the adequacy and effectiveness of our procedures 
to ensure proper compliance.
Compensation Committee. Our compensation committee consists of Mr. Wei Fu, Mr. Chun Kwok Alan Au and Mr. Conor Chia-hung Yang. Mr. Wei 
Fu is the chairperson of our compensation committee. We have determined that each of Mr. Chun Kwok Alan Au and Mr. Conor Chia-hung Yang satisfies 
the “independence” requirements of Rule 5605(a)(2) of the Nasdaq Stock Market Rules. The compensation committee assists the board in reviewing and 
approving the compensation structure, including all forms of compensation, relating to our directors and executive officers. Our chief executive officer may 
not be present at any committee meeting during which his compensation is deliberated. The compensation committee is responsible for, among other 
things:
•
reviewing and approving, or recommending to the board for its approval, the compensation for our chief executive officer and other 
executive officers;
•
reviewing and recommending to the board for determination with respect to the compensation of our directors who are not our employees;
•
reviewing periodically and approving any incentive compensation or equity plans, programs or similar arrangements; and
•
selecting compensation consultant, legal counsel or other adviser only after taking into consideration all factors relevant to that person’s 
independence from management.
Nominating and Corporate Governance Committee. Our nominating and corporate governance committee consists of Mr. Wei Fu, Mr. Chun Kwok 
Alan Au and Mr. Conor Chia-hung Yang. Mr. Wei Fu is the chairperson of our nominating and corporate governance committee. We have determined that 
each of Mr. Chun Kwok Alan Au and Mr. Conor Chia-hung Yang satisfies the “independence” requirements of Rule 5605(a)(2) of the Nasdaq Stock 
Market Rules. The nominating and corporate governance committee assists the board of directors in selecting individuals qualified to become our directors 
and in determining the composition of the board and its committees. The nominating and corporate governance committee is responsible for, among other 
things:
•
selecting and recommending to the board nominees for election by the shareholders or appointment by the board;
•
reviewing annually with the board the current composition of the board with regards to characteristics such as independence, knowledge, 
skills, experience and diversity;
•
making recommendations on the frequency and structure of board meetings and monitoring the functioning of the committees of the board; 
and
•
advising the board periodically with regards to significant developments in the law and practice of corporate governance as well as our 
compliance with applicable laws and regulations, and making recommendations to the board on all matters of corporate governance and on 
any corrective action to be taken.
Environmental, Social and Governance Committee. Our environmental, social and governance (“ESG”) committee consists of Mr. Chun Kwok Alan 
Au and Xi-Yong (Sean) Fu. Mr. Chun Kwok Alan Au is the chairman of our environmental, social and governance committee. In addition, we have also 
established an ESG working group to address daily ESG workflows. The environmental, social and governance committee is responsible for, among other 
things:
•
supervising the ESG strategies, policies, long-term sustainability objectives and risks.

Duties of Directors
Under Cayman Islands law, our directors owe fiduciary duties to our company, including a duty of loyalty, a duty to act honestly, and a duty to act in 
what they consider in good faith to be in our best interests. Our directors must also exercise their powers only for a proper purpose. A director must 
exercise the skill and care of a reasonably diligent person having both (a) the general knowledge, skill and experience that may reasonably be expected of a 
person in the same position (an objective test), and (b) if greater, the general knowledge, skill and experience that that director actually possesses (a 
subjective test). In fulfilling their duty of care to us, our directors must ensure compliance with our memorandum and articles of association, as amended
from time to time, and the class rights vested thereunder in the holders of the shares. Our company has the right to seek damages if a duty owed by our 
directors is breached. A shareholder may in certain limited circumstances have the right to seek damages in our name if a duty owed by the directors is 
breached.
Our board of directors has all the powers necessary for managing, and for directing and supervising, our business affairs. The functions and powers of 
our board of directors include:
•
convening shareholders’ annual general meetings and reporting its work to shareholders at such meetings;
•
declaring dividends and other distributions;
•
appointing officers and determining the term of office of the officers;
•
exercising the borrowing powers of our company and mortgaging the property of our company; and
•
approving the transfer of shares in our company, including the registration of such shares in our share register.
Terms of Directors and Officers
Our directors may be elected by an ordinary resolution of our shareholders. Alternatively, our board of directors may, by the affirmative vote of a 
simple majority of the directors present and voting at a board meeting appoint any person as a director to fill a casual vacancy on our board or as an 
addition to the existing board. Our directors (other than independent directors) are not automatically subject to a term of office and hold office until such 
time as they are removed from office by an ordinary resolution of our shareholders. Our independent directors hold office until the earlier of (i) the date on 
which the independent director ceases to be a member of the board for any reason; (ii) the date of termination of an independent director’s director 
agreement, which may be terminated by either the independent director or by us with a 30-day advance written notice or such other shorter period as 
mutually agreed; or (iii) three years from the effective date of the director agreement, subject to the terms of our current memorandum and articles of 
association of our company. In addition, a director will cease to be a director if he or she (i) becomes bankrupt or makes any arrangement or composition 
with his or her creditors; (ii) dies or is found to be or becomes of unsound mind; (iii) resigns his or her office by notice in writing; (iv) without special leave 
of absence from our board, is absent from meetings of our board for three consecutive meetings and our board resolves that his or her office be vacated; or 
(v) is removed from office pursuant to any other provision of our articles of association.
Our officers are appointed by and serve at the discretion of the board of directors, and may be removed by our board of directors. Under our articles of 
association, the board of directors may appoint one or more of their number to the office of managing director upon like terms, but any such appointment 
should ipso facto terminate if any managing director ceases for any cause to be a director, or if our company by ordinary resolution of shareholders resolves 
that his tenure of office be terminated. In addition, the board of directors may appoint any natural person or corporation to be a secretary (and if need be an 
assistant secretary or assistant secretaries) who should hold office for such term, at such remuneration and upon such conditions and with such powers as 
they think fit. Any secretary or assistant secretary so appointed by the board of directors may be removed by the board of directors or by ordinary 
resolution of shareholders.
D.
Employees.
We had 32, 220, and 318 employees as of December 31, 2024, 2023 and 2022, respectively. As of December 31, 2024, all our employees were in the 
United States. The decrease in employees between 2023 and 2024 is primarily attributable to the divestiture of our Greater China assets and business 
operations in April 2024. The table below sets forth our employees by function as of December 31, 2024:

We recruit our employees primarily through recruitment websites, recruiters, internal referrals and job fairs. Approximately 78% of employees hired 
in 2024 came through internal referrals. Approximately 75% of our employees hold a master’s degree or above. We recruit our employees based on their 
qualification and potential. We prohibit any form of discrimination (including employment, career development, salary, and benefits) on the basis of an 
employees’ gender, race, age, physical condition, sexual orientation, marital status, or disability, so as to ensure a diverse and fair corporate culture.
We believe we offer competitive salaries, benefits, and additional incentives to our employees. Employee compensation and benefits include position-
specific salary, bonus and allowance, statutory insurance, statutory holidays, benefits and vacations, etc., as well as a series of internal morale boosting 
incentive programs. We work to reward employees for exceptional performance.
We provide new hire training to our employees and periodic on-the-job training to enhance the skills and knowledge of our employees. We invest in 
employees’ career development and provide them opportunities to keep updating their skills and knowledge. Our training system includes induction 
training for new employees, training on general knowledge, professional skills training, and leadership training, among which, leadership training focuses 
on improving employees’ knowledge and ability in compliance management, drug quality control, business audit and financial standard procedures. We 
encourage our employees to develop various training courses, and grade the content setting, applicability, practicability, and lecturer quality of the courses, 
to continuously improve them through collecting and addressing feedback. We have not established a labor union. We have not experienced any material 
labor disputes or strikes that may have a material and adverse effect on our business, financial condition or results of operations.
We enter into standard confidentiality agreements with all of our key management and research staff. The contracts with our key personnel typically 
include a standard non-compete agreement that prohibits the employee from competing with us, directly or indirectly, during his or her employment and for 
two years after the termination of his or her employment. The contracts also typically include undertakings regarding assignment of innovations and 
discoveries made during the course of his or her employment. For further details regarding the terms of confidentiality and employment agreements with
our key management, see “Item 6. Directors, Senior Management and Employees.”

Share Ownership.
The following table sets forth information with respect to the beneficial ownership of our ordinary shares as of March 19, 2025 by:
•
each of our directors and executive officers; and

a person and the percentage ownership of that person, we have included shares that the person has the right to acquire within 60 days, including through the 
exercise of any option, warrant or other right or the conversion of any other security. These shares, however, are not included in the computation of the 
percentage ownership of any other person. The beneficial owners

Please refer to “Item 6. Directors, Senior Management and Employees—E. Share Ownership.”
B.
Related Party Transactions
The following is a description of related party transactions we have entered into or been a participant in since January 1, 2024, and in which any of our 
then directors, executive officers or holders of more than 5% of any class of our voting securities at the time of such transaction, or any members of their 
immediate family, had or will have a direct or indirect material interest.
Shareholders Agreement
In July 2019, we entered into our fourth amended and restated shareholders agreement with our then-shareholders.
The shareholders agreement provides for certain special rights, including right of first refusal, co-sale rights, preemptive rights and contains provisions 
governing the board of directors and other corporate governance matters. Those special rights, as well as the corporate governance provisions, 
automatically terminated upon the completion of our initial public offering.
Pursuant to our shareholders agreement, we have granted certain registration rights to our shareholders. Set forth below is a description of the 
registration rights granted under the agreement.
Demand Registration Rights. The holders of a majority of the registrable securities then issued and outstanding may request in writing that we file a 
registration statement covering the registration of at least 20% of the registrable securities (or any lesser percentage if the anticipated gross receipts from 
the offering are to exceed $5.0 million). Upon such a request, we should, within ten business days of the receipt of such written request, give written notice 
of such request to all holders, and use our best efforts to effect, as soon as practicable, the registration of all registrable securities that the holders request to 
be registered and included in such registration by written notice given by such holders to us within 20 days after receipt of the request notice. We have the 
right to defer filing of a registration statement for a period of not more than 90 days after receipt of the request of the initiating holders if our board of 
directors determines in good faith that filing of such registration statement at such time will be materially detrimental to us or our shareholders, but we 
cannot exercise the deferral right more than once during any twelve-month period and cannot register any other securities during such twelve-month period. 
We are not obligated to effect any such registration if we have, within the six-month period preceding the date of such request, already effected a 
registration. We are not obligated to effect more than three demand registrations. This demand registration right is subject to the customary exclusion right 
of the underwriters.
Registration on Form F-3. If we qualify for registration on Form F-3, any holder or holders of a majority of all registrable securities then issued and 
outstanding may request in writing that we effect a registration on Form F-3 (or an equivalent registration in a jurisdiction outside of the United States). We 
should promptly give written notice of the proposed registration and as soon as practicable, effect such registration within 20 days after we provide the 
aforesaid written notice. The holders are entitled to an unlimited number of registrations on Form F-3 so long as such registration offerings are in excess of 
$500,000. We are not obligated to effect any such registration if we have, within the six-month period preceding the date of such request, already effected a 
registration other than a registration from which registrable securities of the holders have been excluded, or if we would be required to qualify to do 
business or to execute a general consent to service of process in effecting such registration in any particular jurisdiction.
Piggyback Registration Rights. If we propose to register for a public offering of our securities (other than registration statements relating to demand 
registration, Form F-3 registration, any employee benefit plan or a corporate reorganization), we should give written notice of such registration to all 
holders of registrable securities at least 30 days prior to filing any registration statement and afford each such holder an opportunity to be included in such 
registration. If a holder decides not to include all of its registrable securities in any registration statement thereafter filed by us, such holder will 
nevertheless continue to have the right to include any registrable securities in any subsequent registration statement or registration statements as may be 
filed by us, subject to certain limitations. This piggyback registration right is subject to the customary exclusion right of the underwriters.
Expenses of Registration.
We will bear all registration expenses. Each holder, however, should bear its proportionate share of all of the underwriting discounts and selling 
commissions applicable to the sale of registrable securities or other amounts payable to underwriter(s) or brokers in connection with such offering by the
holders.

Table of Contents
Termination of Obligations.
Our obligations to effect any demand, Form F-3 or piggyback registration will terminate upon the earlier of (i) January 22, 2030, which is the tenth 
anniversary of our initial public offering, or (ii) with respect to any shareholder, the date on which such shareholder is eligible to sell all of the registrable 
securities held by it under Rule 144 within any 90-day period without volume limitations.
Deed of Undertaking
In December 2019, a deed of undertaking was made by our company and a few shareholders of our company, each as a warrantor, to the other 
shareholders of our company (other than the shareholder warrantors), each as a warrantee, pursuant to which each warrantor represents and warrants to 
each warrantee that it has provided each warrantee with all information and documents in connection with our initial public offering that has the effect of 
establishing rights or otherwise benefiting any shareholder in a manner more favorable than the corresponding terms applicable to the warrantee in relation 
to our initial public offering (collectively, the “More Favorable Arrangements”). Pursuant to the deed of undertaking, until the fifth anniversary of the 
completion of our initial public offering, we will not directly or indirectly enter into any agreements or arrangements or modify, amend or waive any 
existing agreements or arrangements of any kind that would have the effect of establishing the More Favorable Arrangements; provided that it will be 
allowed to adopt or modify any employee incentive plans and grant options to the management or any employee of our company after our initial public 
offering pursuant to such plans and in accordance with the then effective memorandum and articles of association and the applicable listing rules for the 
purpose of rewarding their bona fide services.
Subscription Agreement with Hillhouse Entities
In September 2020, we entered into a Subscription Agreement with the Hillhouse Entities, as amended by an amendment to Subscription Agreement 
entered into between Hillhouse Entities and our company in December 2020. The Subscription Agreement, as amended, provides for (i) certain investors’ 
rights, such as registration rights, board representation rights and anti-dilution rights and (ii) lock-up and other transfer restrictions. Set forth below is a 
description of certain rights and restrictions thereof.
Demand Registration Rights. Upon written request from the Hillhouse Entities at any time after we have effected two registration statements 
abovementioned, with respect to the registrable securities then held by the Hillhouse Entities, and in no event later than the forty-five (45) calendar days 
following the delivery of such request, we should file a prospectus supplement or a registration statement to register the resale of such registrable securities 
on a Form F-3 or Form F-3ASR registration statement (or, if Form F-3 or Form F-3ASR is not then available to us, on Form F-1 or such other form of 
registration statement as is then available to effect a registration for resale of such registrable securities), have such registration statement declared 
effective, and maintain the effectiveness of such registration statement for a period ending on the date the registrable securities registered thereon have 
ceased to be registrable securities. If the registrable securities are offered by means of an underwritten offering, and we or the underwriters determine that 
marketing factors require a limitation of the number of securities to be underwritten, the number of registrable securities that may be included in the 
underwriting should be reduced and allocated (i) first, to us and each holder in accordance with the terms of the Shareholders Agreement; (ii) second, to 
investors in the private placements entered into in September 2020 (including the Hillhouse Entities) requesting inclusion of their registrable securities in 
such registration statement on a pro rata basis based on the total number of registrable securities then held by each such investor; and (iii) third, to other 
holders of registrable securities, if any.
Suspension of Registration. We may suspend the use of any registration statement for a period not exceeding thirty (30) consecutive trading days, if 
we (i) determine that we would be required to make disclosure of material information in the registration statement that we have a bona fide business 
purpose for preserving as confidential; (ii) determine that we must amend or supplement the registration statement so that it does not include an untrue 
statement of a material fact or omit to state a material fact; or (iii) have experienced or are experiencing some other material non-public event, the 
disclosure of which at such time would adversely affect us. However, we cannot exercise the suspension right more than once in any twelve (12) month 
period and may not register any other securities during such suspension period.
Expenses. We will bear all registration expenses, except any (i) portions of fees and disbursements of counsel for the Hillhouse Entities exceeding 
$30,000, (ii) underwriting discounts and selling commissions applicable to sale of registrable securities, and (iii) fees payable pursuant to the deposit 
agreement.
Ranking of Registration Rights. Registration rights granted to the Hillhouse Entities should not be senior to, or on a parity with, those granted to 
holders under the Shareholders Agreement.
Board Representation Rights. As long as the Hillhouse Entities continue to jointly beneficially own at least five percent (5.0%) of our total issued and 
outstanding share capital, it is entitled to nominate and maintain one representative to our board of directors. We should cause an individual jointly 
designated by the Hillhouse Entities to be appointed as the investor director with immediate effect no

later than the fifteenth business day after receiving written notice from Hillhouse Entities or such later date on which we receive necessary shareholder 
approval.
Divestiture of Our Greater China Assets and Business Operations
On February 6, 2024, we entered into definitive agreements to divest our Greater China assets and business operations to TJBio Hangzhou, and the 
divestiture of business operations in China was completed on April 2, 2024. Pursuant to the divestiture, we transferred 100% of the outstanding equity 
interest in TJBio Shanghai, which operates our business in China, on a cash-free and debt-free basis, to TJBio Hangzhou, including our rights to the 
Greater China portfolio, for an aggregate consideration of the RMB equivalent of up to $80 million, contingent on the achievement of certain future 
regulatory and sales-based milestone events as well as royalties. After the completion of the divestiture, we no longer own any rights to the Greater China 
portfolio. The transaction also extinguished existing repurchase obligations owed by a wholly-owned subsidiary of ours in the amount of approximately 
$183 million. As of December 31, 2024, all remaining repurchase obligations have been fully extinguished.
Secondment Agreement
On August 28, 2024, in connection with Dr. Fu’s appointment as Interim CEO, ABio-X entered into the Secondment Agreement with I-Mab 
Biopharma US, a wholly-owned subsidiary of the Company, pursuant to which Dr. Fu was seconded by ABio-X to the I-Mab Group, to serve as Interim 
CEO of the I-Mab Group on a substantially full-time basis. Pursuant to the Secondment Agreement, Dr. Fu was secondment with I-Mab Group for a six-
month period, effective as of July 15, 2024 (the “Secondment Period”). Thereafter, the Secondment Agreement will automatically renew for successive 
one-month terms, or as otherwise agreed upon by mutual written agreement of ABio-X and I-Mab US. During Dr. Fu’s secondment, Dr. Fu received a 
monthly salary of $50 thousand, subject to tax withholding to the extent required by law, and continued to receive the benefits provided to him by ABio-X 
at the time. I-Mab Biopharma US paid Dr. Fu’s monthly salary to ABio-X, and ABio-X then paid such amount to Dr. Fu in accordance with the 
Secondment Agreement. In addition, Dr. Fu’s benefit expenses incurred by ABio-X during the Secondment Period were reimbursed by I-Mab Biopharma 
US. On November 1, 2024, in connection with Dr. Fu’s appointment as the Company’s permanent Chief Executive Officer, the Secondment Agreement 
was terminated. Dr. Fu received approximately $231 thousand pursuant to the Secondment Agreement. ABio-X is a wholly-owned subsidiary of C-Bridge 
V Investment Holding Limited, which is a wholly-owned subsidiary of C-Bridge Healthcare Fund V, L.P. As disclosed in this annual report, C-Bridge 
Healthcare Fund V, L.P. and its affiliates hold more than 15% of the total outstanding shares of the Company.

Other Transactions with Related Parties 
In December 2021, we entered into a supplementary sublicensing agreement with TJBio Hangzhou, pursuant to which TJBio Hangzhou, as a sub-
licensee of olamkicept (TJ301) in Greater China and Korea, agreed to pay $3.0 million to us for the completion of olamkicept (TJ301) Phase 2a study 
report. After receiving the milestone payment of $3.0 million from TJBio Hangzhou, we made the payment of $3.0 million to Ferring during 2022. 
In May 2022, we entered into an amended and restated license and sublicense agreement and a cell line and manufacturing collaboration agreement 
with Ferring, under which we granted to Ferring an exclusive, perpetual and transferable sublicense, with the right to grant further sublicenses to 
sublicensees, under all of the intellectual properties licensed to us by our business partner, to research, develop, make, import, use and sell olamkicept as 
expressed by or produced by cell lines created by our business partner and its affiliates in any human indications in the territories other than Greater China 
and Korea. We also granted to Ferring an exclusive, perpetual and royalty-free license, with right of sublicense to sublicensees, under the intellectual 
property owned or controlled by our company which relates to cell lines created by our business partner and its affiliates, for the research, development, 
making, using or selling of olamkicept, including prespecified patents and know-how and improvements thereto. In December 2022, we delivered the data 
package defined in the first milestone of the amended and restated license and sublicense agreement with Ferring and recognized $5.5 million of revenue. 
We subsequently paid to TJBio Hangzhou $2.75 million and reduced the amount of revenue recognized by such amount.

On July 16, 2022, TJBio Hangzhou entered into a definitive financing agreement with a group of domestic investors in China to raise the RMB 
equivalent of approximately $46 million. On the same date, we, through our wholly-owned subsidiary, entered into a shareholders agreement with TJBio 
Hangzhou and other domestic investors in TJBio Hangzhou named therein.
In connection with the divestiture of our Greater China assets and business operations, we participated in the Series C fundraising of TJBio Hangzhou 
for an equity interest subscription of $19.0 million in cash.
As of April 2, 2024, TJBio Hangzhou is no longer a related party.

Legal Proceedings
From time to time we may become involved in legal proceedings or be subject to claims arising in the ordinary course of our business. Regardless of 
the outcome, litigation or arbitration can have an adverse impact on us because of defense and settlement costs, diversion of management resources and 
other factors. We are not presently a party to any legal proceedings that, if determined adversely to us, would individually or taken together have a material 
adverse effect on our business, results of operations, financial condition or cash flows.
In April 2020, Tracon issued a notice of disputes with respect to the agreements we entered into with it to co-develop TJD5 and bispecific antibodies, 
respectively. In February 2021, we sent Tracon a notice to terminate the agreement we entered into with Tracon to co-develop TJD5, which would result in 
a prespecified termination fee of $9.0 million owing to Tracon. Accordingly, we have already accrued and recorded this termination fee of $9.0 million as 
administrative expenses in our consolidated financial statements for the year ended December 31, 2021. The disputes were presented to a binding 
arbitration proceeding under the Rules of Arbitration of the International Chamber of Commerce before an arbitration tribunal. On April 25, 2023, we 
announced positive outcomes in the arbitration. The arbitration award determined that the agreement in relation to TJD5 has been terminated for a pre-
agreed termination fee of $9.0 million plus interest payable pursuant to the original agreement, and, therefore Tracon has no rights to share any future 
economics with I-Mab. The arbitration award completely denied Tracon’s damages claim of over $200.0 million for any breach and awarded no damages 
to Tracon. The tribunal also confirmed the termination of the agreement in relation to bispecific antibodies. Based on the arbitration award, I-Mab bears a 
portion of Tracon’s legal fees and costs, totaling approximately $13.5 million, which was recorded as administrative expenses in our consolidated financial 
statements for the year ended December 31, 2022. In July 2023, I-Mab paid the pre-agreed termination fee in relation to TJD5 and the agreed-upon portion 
of Tracon’s legal fees and costs to Tracon. The financial impacts of the transaction were allocated to discontinued operations for the periods presented.
Furthermore, on January 31, 2024, Ningbo Yanyuan Yaoshang Industry Finance Equity Investment Partnership (Limited Partnership), or Yanyuan 
Yaoshang, Ningbo Yanchuang Yaoshang Yangming Entrepreneurship Investment Partnership (Limited Partnership), or Yanyuan Yangming, Jiangsu 
Yanyuan Eastern Entrepreneurship Equity Investment Partnership (Limited Partnership), or Yanyuan Eastern, Ningbo Rongshun Yanyuan 
Entrepreneurship Equity Investment Partnership (Limited Partnership), or Rongshun Yanyuan, and Ningbo Yanyuan Innovation Entrepreneurship Equity 
Investment Partnership (Limited Partnership), or Yanyuan Innovation, (collectively “Claimants”), as shareholders of I-Mab Hangzhou, commenced 
arbitration against I-Mab Hong Kong before China International Economic and Trade Arbitration Commission Zhejiang Sub-Commission. The Claimants 
seek the following relief: (1) an order that I-Mab Hong Kong pays Yanyuan Yaoshang the equity transfer payment and premium in total amount of $2.67 
million as of January 29, 2024; (2) an order that I-Mab Hong Kong pays Yanyuan Yangming the equity transfer payment and premium in total amount of 
$4.27 million as of January 29, 2024; (3) an order that I-Mab Hong Kong pays Yanyuan Eastern the equity transfer payment and premium in total amount 
of $3.74 million as of January 29, 2024; (4) an order that I-Mab Hong Kong pays Rongshun Yanyuan the equity transfer payment and premium in total 
amount of $3.34 million as of January 29, 2024; (5) an order that I-Mab Hong Kong pays Yanyuan Innovation the equity transfer payment and premium in 
total amount of $3.34 million as of January 29, 2024; (6) an order that I-Mab Hong Kong pays all arbitration fees and property preservation fees incurred 
by the Claimants. As of June 30, 2024, we reached a settlement and paid the RMB equivalent of $17.3 million to the Claimants from funds previously 
placed into escrow and completed the equity transfer thereafter.
On March 1, 2022, we filed a complaint in the United States District Court for the District of Delaware, naming Inhibrx, Inc. (“Inhibrx”) and Dr. 
Brendan Eckelman as defendants (together “the Defendants”). This trial was related to the litigation against the Defendants’ alleged misappropriation of the 
Company’s preclinical and clinical trade secret data, allegedly obtained by Dr. Eckelman while acting as an expert witness for Tracon. The Company 
sought damages in the form of a lump sum reasonable royalty, along with exemplary damages for Defendants’ willful and malicious misappropriation. The 
judge bifurcated for a later bench trial the Company’s claims related to Defendants’ misappropriation of its business trade secret information. On 
November 1, 2024, a federal jury in the United States District Court for the District of Delaware found in favor of the Defendants in this bifurcated trial 
relating to a portion of the Company’s trade secret information.
Regardless of the outcome, litigation or arbitration can have an adverse impact on us because of defense and settlement costs, diversion of 
management resources and other factors. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret can be difficult, expensive and 
time-consuming, and the outcome is unpredictable.

Dividend Policy
Our board of directors has complete discretion on whether to pay dividends, subject to certain requirements of Cayman Islands law. Even if our board 
of directors decides to pay dividends on our ordinary shares, the form, frequency and amount will depend upon our future operations and earnings, capital 
requirements and surplus, general financial condition, contractual restrictions and other factors that our board of directors may deem relevant.
We do not have any present plan to pay any cash dividends on our ordinary shares in the foreseeable future. We currently intend to retain most, if not 
all, of our available funds and any future earnings to operate and develop our business.
We are a holding company incorporated in the Cayman Islands. We may rely on dividends from our subsidiaries in the United States and China for 
our cash requirements, including any payment of dividends to our shareholders. PRC regulations may restrict the ability of our PRC subsidiary to pay 
dividends to us. See “Item 4. Information on the Company—B. Business Overview—Regulation—PRC Regulation—Regulations Relating to Foreign 
Exchange and the Dividend Distribution.”
If we pay any dividends on our ordinary shares, we will pay those dividends which are payable in respect of the ordinary shares underlying our ADSs 
to the depositary, as the registered holder of such ordinary shares, and the depositary then will pay such amounts to our ADS holders in proportion to the 
ordinary shares underlying the ADSs held by such ADS holders, subject to the terms of the deposit agreement, including the fees and expenses payable 
thereunder. Cash dividends on our ordinary shares, if any, will be paid in U.S. dollars.
B.
Significant Changes
On January 28, 2025, we completed a workforce reduction designed to improve operational efficiencies and realign the Company’s clinical 
development support as a result of the Company’s recently announced pipeline reprioritization (the “Realignment Plan”). The Realignment Plan reduced 
the Company’s workforce by approximately 27%.
We incurred charges associated with the Realignment Plan in 2025 of approximately $0.8 million primarily related to employee severance payments, 
benefits and related termination costs. The Realignment Plan is expected to result in annual operating expense savings of approximately $3.0 million.

Memorandum and Articles of Association 
The following is a summary of the material provisions of the sixth amended and restated memorandum and articles of association of our company and 
of the Companies Act, insofar as they relate to the material terms of our ordinary shares.
Objects of Our Company. Under our current 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 Companies Act or any other law of the Cayman Islands.
Ordinary Shares. Certificates representing the ordinary shares are issued in registered form and our ordinary shares are issued when registered in our 
register of members. We may not issue shares to bearers. Our shareholders who are non-residents of the Cayman Islands may freely hold and vote their 
shares.
Dividends. Our directors may from time to time declare dividends (including interim dividends) and other distributions on our shares in issue and 
authorize payment of the same out of the funds of our company lawfully available therefor. In addition, our company may declare dividends by ordinary 
resolution, but no dividend should exceed the amount recommended by our directors. Our current memorandum and articles of association provide that 
dividends may be declared and paid out of the funds of our company lawfully available therefor. Under the laws of the Cayman Islands, our company may 
pay a dividend 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 meeting of shareholders is by show of hands unless a poll is demanded. A poll may be demanded by the chairman of 
such meeting or any one shareholder or shareholders collectively holding not less than 5% of the votes attaching to the shares present in person or by 
proxy.
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 not less than two-thirds of the votes attaching to the ordinary 
shares cast at a meeting. A special resolution will be required for important matters such as a change of name or making changes to our current 
memorandum and articles of association.
Alteration of Share Capital
We 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 prescribes;
•
consolidate and divide all or any of our share capital into shares of a larger amount than its existing shares;
•
subdivide our shares, or any of them, into shares of an amount smaller than that fixed by the memorandum of association, provided that in the 
subdivision the proportion between the amount paid and the amount, if any, unpaid on each reduced share should be the same as it was in case of 
the share from which the reduced share is derived; and
•
cancel any shares that, 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 its share capital by the amount of the shares so cancelled.
We may by special resolution, subject to any confirmation or consent required by the Companies Act, reduce our share capital and any capital 
redemption reserve in any manner authorized by law.
General Meetings of Shareholders. As a Cayman Islands exempted company, we are not obliged by the Companies Act to call shareholders’ annual 
general meetings. Our current memorandum and articles of association provide that we may (but are not obliged to) in each calendar year hold a general 
meeting as our annual general meeting in which case we should specify the meeting as such in the notices calling it, and the annual general meeting will be 
held at such time and place as may be determined by our directors.

 
128
Table of Contents
Shareholders’ general meetings may be convened by our directors (acting by a resolution of our board). Advance notice of at least 14 calendar days is 
required for any general shareholders’ meeting. A quorum required for any general meeting of shareholders consists of, at the time when the meeting 
proceeds to business, one or more of our shareholders holding shares which carry in aggregate (or representing by proxy) not less than one-third of all votes 
attaching to all of our shares in issue and entitled to vote at such general meeting.
The 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 current articles of 
association allow our shareholders holding in aggregate not less than one-tenth of all votes attaching to all issued and outstanding shares of our company 
that as at the date of the deposit carry the right to vote at general meetings of the company 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. However, our current 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.
Transfer of Ordinary Shares. Subject to the restrictions in our current memorandum and articles of association as 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:
•
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 Global 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 directors refuse to register a transfer, they should, within three calendar months after the date on which the instrument of transfer was lodged 
with our company, send to each of the transferor and the transferee notice of such refusal.
The registration of transfers may, on ten calendar days’ notice being given by advertisement in such one or more newspapers, by electronic means or 
by any other means in accordance with the rules of the Nasdaq Global 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 should not be suspended nor the register 
closed for more than 30 calendar days in any calendar year.
Liquidation. On the winding up of our company, if the assets available for distribution amongst our shareholders are more than sufficient to repay the 
whole of the share capital at the commencement of the winding up, the surplus should 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.
Calls on Shares and Forfeiture of Shares. Subject to the terms of the allotment, our board of directors may from time to time make calls upon 
shareholders in respect of any moneys unpaid on their shares in a notice served to such shareholders at least 14 calendar 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 Shares. We may issue shares on terms that such shares are subject to redemption, at our option or at the 
option of the holders of these shares, 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 a special resolution. Our company may also repurchase any of our shares on such terms and in such manner as have been approved 
by our board of directors or by an ordinary resolution of our shareholders or are 

 
129
Table of Contents
otherwise authorized by the articles of association. Under Cayman Islands law, any redemption or repurchase of shares by our company may be made out 
of 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 our company can, immediately following such payment, pay its debts as they fall due in the ordinary 
course of business. 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 our 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. Whenever the capital of our company is divided into different classes the rights attached to any such class may, subject 
to any rights or restrictions for the time being attached to any class, only be varied with the consent in writing of the holders of all of the issued shares of 
that class or with the sanction of a special resolution passed at a separate meeting of the holders of the shares of that class. The rights conferred upon the 
holders of the shares of any class issued with preferred or other rights should not, subject to any rights or restrictions for the time being attached to the 
shares of that class, be deemed to be varied by, inter alia, the creation, allotment or issue of further shares ranking pari passu with or subsequent to them or 
the redemption or purchase of any shares of any class by our company. The rights of the holders of shares should not be deemed to be varied by the 
creation or issue of shares with preferred or other rights, including, without limitation, the creation of shares with enhanced or weighted voting rights.
Issuance of Additional Shares. Our current memorandum and articles of association authorize our board of directors to issue additional ordinary shares 
from time to time as our board of directors determines.
Our current memorandum and articles of association also authorize our board of directors to issue 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 preferred shares to constitute such series;
•
the dividend rights, dividend rates, conversion rights, voting rights; and
•
the rights and terms of redemption and liquidation preferences.
Issuance of these shares may dilute the voting power of holders of ordinary shares.
Inspection of Books and Records. A list of the names of the current directors and alternate directors (if applicable) are made available by the Registrar 
of Companies of the Cayman Islands for inspection by any person on payment of a fee. Shareholders have no general right under Cayman Islands law to 
inspect or obtain copies of our register of members or our corporate records (save for our memorandum and articles of association, our register of 
mortgages and charges and special resolutions of our shareholders). However, we intend to provide our shareholders with annual audited financial 
statements.
Anti-Takeover Provisions. Some provisions of our current 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.
However, under Cayman Islands law, our directors may only exercise the rights and powers granted to them under our current 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.
Exempted Company. We are an exempted company with limited liability incorporated under the Companies Act. The 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 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;

 
130
Table of Contents
•
may issue 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 held 
by such shareholder (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).

Material Contracts
We have not entered into any material contracts other than in the ordinary course of business and other than those described under this item, in “Item 
4. Information on the Company,” “Item 7. Major Shareholders and Related Party Transactions—B. Related Party Transactions,” “Item 10. Additional 
Information—C. Material Contracts” or elsewhere in this annual report on Form 20-F.

E.
Taxation
The following summary of the material Cayman Islands, PRC and U.S. federal income tax consequences of an investment in the ADSs or ordinary 
shares is based upon laws and interpretations thereof in effect as of the date of this annual report, all of which are subject to change. This summary does not 
deal with all possible tax consequences relating to an investment in the ADSs or ordinary shares, such as the tax consequences under U.S. state and local 
tax laws or under the tax laws of jurisdictions other than the Cayman Islands, China and the United States.
Cayman Islands Taxation 
According to Harney Westwood & Riegels, our Cayman Islands counsel, the Cayman Islands currently levies no taxes on individuals or corporations 
based upon profits, income, gains or appreciation and there is no taxation in the nature of inheritance tax or estate duty. There are no other taxes likely to be 
material to holders of our ADSs or ordinary shares levied by the government of the Cayman Islands, except for stamp duties, which may be applicable on 
instruments executed in, or brought to, or produced before a court of the Cayman Islands. The Cayman Islands has a double tax treaty with the United 
Kingdom entered into force in 2010 but otherwise is not party to any double tax treaties. There are no exchange control regulations or currency restrictions 
in the Cayman Islands.
Payments of dividends and capital in respect of our 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 shares, nor will gains derived from the disposal of our shares be subject to Cayman Islands 
income or corporation tax.
No stamp duty is payable in respect of the issue of shares by our company and no stamp duty is payable on transfers of shares of our company 
provided our company does not hold any interest in land in the Cayman Islands and save that stamp duties may be applicable on instruments executed in, or 
brought to, or produced before a court of the Cayman Islands.
PRC Taxation 
Under the PRC Enterprise Income Tax Law and its implementation rules, an enterprise established outside China with “de facto management body” 
within China is considered as a Tax Resident Enterprise for PRC enterprise income tax purposes and is generally subject to a uniform 25% enterprise 
income tax rate on its worldwide income. The implementation rules define the term “de facto management body” as the body that exercises full and 
substantial control and overall management over the business, productions, 

 
131
Table of Contents
personnel, accounts and properties of an enterprise. In April 2009, the State Administration of Taxation issued the Circular of the State Administration of 
Taxation on Issues Relating to Identification of PRC-Controlled Overseas Registered Enterprises as Resident Enterprises in Accordance With the De Facto 
Standards of Organizational Management, or SAT Circular 82, which provides certain specific criteria for determining whether the “de facto management 
body” of a PRC-controlled enterprise that is incorporated offshore is located in China. Although this circular only applies to offshore enterprises controlled 
by PRC enterprises or PRC enterprise groups, not those controlled by PRC individuals or foreigners, the criteria set forth in the circular may reflect the 
State Administration of Taxation’s general position on how the “de facto management body” text should be applied in determining the tax resident status of 
all offshore enterprises. According to SAT Circular 82, an offshore incorporated enterprise controlled by a PRC enterprise or a PRC enterprise group is 
regarded as a PRC tax resident by virtue of having its “de facto management body” in China if all of the following conditions are met: (i) the primary 
location of the day-to-day operational management is in China; (ii) decisions relating to the enterprise’s financial and human resource matters are made or 
are subject to approval by organizations or personnel located in China; (iii) the enterprise’s primary assets, accounting books and records, company seals, 
and board and shareholder resolutions, are located or maintained in China; and (iv) at least 50% of voting board members or senior executives habitually 
reside in China.
Our PRC counsel, JunHe LLP, is of the opinion that, based on its understanding of the current PRC Laws and Regulations, as I-Mab does not meet all 
of the above conditions and given that neither I-Mab nor any of its PRC Subsidiaries has received any notice from the PRC tax authorities confirming, 
directly or indirectly, that I-Mab is a PRC resident enterprise for PRC enterprise income tax purposes as of the date of this annual report, I-Mab should not 
be considered as a PRC resident enterprise for PRC enterprise income tax purposes as of the date of this annual report.
I-Mab is incorporated outside of China and it is not controlled by a PRC enterprise or PRC enterprise group. We have structured a clear management 
guideline in place to segregate the policy set up and business operating execution responsibilities in order to differentiate the effective control from our 
headquarter office and subsidiaries including record keeping and offshore work location plan.
I-Mab is a company incorporated outside the PRC. As a holding company, its key assets are its ownership interests in its subsidiaries, and its key 
assets are located, and its records (including the resolutions of its board of directors and the resolutions of its shareholders) are maintained, outside China. 
However, the tax resident status of an enterprise is subject to determination by the PRC tax authorities and uncertainties remain with respect to the 
interpretation of the term “de facto management body.” We cannot guarantee our investors that PRC tax authorities will not take a different view.
If the PRC tax authorities determine that I-Mab is a PRC resident enterprise for enterprise income tax purposes, our worldwide income could be 
subject to 25% enterprise income tax; and any dividends payable to non-resident enterprise holders of our common shares or ADSs may be treated as 
income derived from sources within China and therefore, subject to a 10% withholding tax (or 20% in the case of non-resident individual holders) unless an 
applicable income tax treaty provides otherwise. In addition, capital gains realized by non-resident enterprise shareholders (including our ADS holders) 
upon the disposition of our common shares or ADSs may be treated as income derived from sources within PRC and therefore, subject to 10% income tax 
(or 20% in the case of non-resident individual shareholders or ADS holders) unless an applicable income tax treaty provides otherwise. It is unclear 
whether non-PRC shareholders of our company would be able to claim the benefits of any tax treaties between their country of tax residence and the PRC 
in the event that we are treated as a PRC resident enterprise.
U.S. Federal Income Tax Considerations 
The following discussion is a summary of certain material U.S. federal income tax considerations relating to the ownership and disposition of our 
ADSs or ordinary shares by a U.S. Holder (as defined below) that acquires our ADSs or ordinary shares and holds our ADSs or ordinary shares as “capital 
assets” (generally, property held for investment) under the U.S. Internal Revenue Code of 1986 as (the “Code”). This discussion is based upon the Code, 
U.S. Treasury Regulations promulgated thereunder, and administrative and judicial interpretations thereof, in each case as in effect on the date hereof and 
subject to differing interpretations or change, possibly with retroactive effect. There can be no assurance that the Internal Revenue Service, or IRS, or a 
court will not take a contrary position. This discussion does not address the estate, gift, Medicare, and alternative minimum tax considerations, or any state, 
local, and non-U.S. tax considerations, relating to the ownership or disposition of our ADSs or ordinary shares or the special tax accounting rules under 
Section 451(b) of the Code. This discussion, moreover, does not discuss all aspects of U.S. federal income taxation that may be important to particular 
investors in light of their individual investment circumstances or to investors subject to special tax situations such as:
•
banks and other financial institutions;
•
insurance companies;
•
pension plans;

•
cooperatives;
•
regulated investment companies;
•
real estate investment trusts;
•
broker-dealers;
•
traders in securities that elect to use a mark-to-market method of accounting;
•
certain former U.S. citizens or long-term residents;
•
tax-exempt entities (including private foundations);
•
governmental entities;
•
investors who are not U.S. Holders;
•
investors who own (directly, indirectly or constructively) 10% or more of our stock (by vote or value);
•
investors who acquire their ADSs or ordinary shares pursuant to any employee share option or otherwise as compensation;
•
investors that will hold their ADSs or ordinary shares as part of a straddle, hedge, conversion, constructive sale or other integrated transaction for 
U.S. federal income tax purposes; or
•
investors that have a functional currency other than the U.S. dollar;
all of whom may be subject to tax rules that differ significantly from those discussed below. Each U.S. Holder is urged to consult its tax advisor 
regarding the U.S. federal, state, and local and non-U.S. income and other tax considerations of an investment in our ADSs or ordinary shares.
For purposes of this discussion, a “U.S. Holder” is a beneficial owner of our ADSs or ordinary shares that is, for U.S. federal income tax purposes, (i) 
an individual who is a citizen or resident of the United States, (ii) a corporation (or other entity treated as a corporation for U.S. federal income tax 
purposes) created in, or organized under the law of, the United States or any state thereof or the District of Columbia, (iii) an estate the income of which is 
includible in gross income for U.S. federal income tax purposes regardless of its source, or (iv) a trust (A) the administration of which is subject to the 
primary supervision of a U.S. court and which has one or more U.S. persons who have the authority to control all substantial decisions of the trust or (B) 
that has otherwise validly elected to be treated as a U.S. person under the Code.
If a partnership (or other entity treated as a partnership for U.S. federal income tax purposes) is a beneficial owner of our ADSs or ordinary shares, the 
tax treatment of a partner in the partnership will generally depend upon the status of the partner and the activities of the partner and the partnership. 
Partnerships holding our ADSs or ordinary shares and their partners are urged to consult their tax advisors regarding an investment in our ADSs or ordinary 
shares.
For U.S. federal income tax purposes, it is generally expected that a U.S. Holder of ADSs will be treated as the beneficial owner of the underlying 
shares represented by the ADSs. The remainder of this discussion assumes that a U.S. Holder of our ADSs will be treated as the beneficial owner of the 
underlying shares represented by the ADSs. Accordingly, deposits or withdrawals of ordinary shares for ADSs will generally not be subject to U.S. federal 
income tax.
Dividends
Subject to the discussion below under “—Passive Foreign Investment Company Considerations,” any cash distributions (including the amount of any 
tax withheld) paid on our ADSs or ordinary shares out of our current or accumulated earnings and profits, as determined under U.S. federal income tax 
principles, will generally be includible in the gross income of a U.S. Holder as dividend income on the day actually or constructively received by the U.S. 
Holder. Because we do not intend to determine our earnings and profits on the basis of U.S. federal income tax principles, any distribution we pay will 
generally be reported as a “dividend” for U.S. 

 
133
Table of Contents
federal income tax purposes. Dividends received on our ADSs or ordinary shares will not be eligible for the dividends received deduction allowed to 
corporations in respect of dividends received from U.S. corporations.
A non-corporate U.S. Holder will generally be subject to tax on dividend income from a “qualified foreign corporation” at a lower applicable capital 
gains rate rather than the marginal tax rates generally applicable to ordinary income provided that certain conditions are satisfied, including that (1) our 
ADSs or ordinary shares on which the dividends are paid are readily tradable on an established securities market in the United States (2) we are neither a 
PFIC nor treated as such with respect to a U.S. Holder for the taxable year in which the dividend is paid and the preceding taxable year; and (3) certain 
holding period requirements are met. Our ADSs (but not our ordinary shares) are listed on the Nasdaq Global Market and we anticipate that our ADS 
should be considered readily tradable on an established securities market in the United States. There can be no assurance, however, that our ADSs will be 
considered readily tradable on an established securities market. Since we do not expect that our ordinary shares will be listed on an established securities 
market, we do not believe that dividends that we pay on our ordinary shares that are not represented by ADSs will meet the conditions required for the 
reduced tax rate.
Dividends will generally be treated as income from foreign sources for U.S. foreign tax credit purposes and will generally constitute passive category 
income. In the event that we are deemed to be a PRC resident enterprise under the PRC Enterprise Income Tax Law, a U.S. Holder may be subject to PRC 
withholding taxes on dividends paid on our ADSs or ordinary shares. See “—PRC Taxation” above. In that case, depending on the U.S. Holder’s individual 
facts and circumstances, a U.S. Holder may be eligible, subject to a number of complex limitations, to claim a foreign tax credit not in excess of any 
applicable treaty rate in respect of any foreign withholding taxes imposed on dividends received on our ADSs or ordinary shares. A U.S. Holder who does 
not elect to claim a foreign tax credit for foreign tax withheld may instead claim a deduction, for U.S. federal income tax purposes, in respect of such 
withholding, but only for a year in which such holder elects to do so for all creditable foreign income taxes. The rules governing the foreign tax credit are 
complex and their outcome depends in large part on the U.S. Holder’s individual facts and circumstances. Accordingly, U.S. Holders are urged to consult 
their tax advisors regarding the availability of the foreign tax credit under their particular circumstances.
As discussed above, we believe that we were a PFIC for the taxable year ended December 31, 2023, and we will likely be classified as a PFIC for our 
current taxable year. U.S. Holders are urged to consult their tax advisors regarding the availability of the reduced rate of taxation on dividends with respect 
to our ADSs or ordinary shares under their particular circumstances.
Sale or Other Disposition of ADSs or Ordinary Shares
Subject to the discussion below under “—Passive Foreign Investment Company Rules,” a U.S. Holder will generally recognize capital gain or loss 
upon the sale or other disposition of ADSs or ordinary shares in an amount equal to the difference between the amount realized upon the disposition and 
the holder’s adjusted tax basis in such ADSs or ordinary shares. Any capital gain or loss will be long-term if the ADSs or ordinary shares have been held 
for more than one year and will generally be U.S. source gain or loss for U.S. foreign tax credit purposes. Long-term capital gain of non-corporate U.S. 
Holders is generally eligible for a reduced rate of taxation. The deductibility of a capital loss is subject to limitations. The rules regarding foreign tax credits 
and deduction of foreign taxes are complex. U.S. Holders should consult their tax advisors regarding the availability of a foreign tax credit or deduction in 
light of their particular circumstances, including their eligibility for benefits under the United States-PRC income tax treaty and the potential impact of U.S. 
Treasury Regulations.
As discussed below, we believe that we were a PFIC for the taxable year ended December 31, 2024, and we will likely be classified as a PFIC for our 
current taxable year. U.S. Holders are urged to consult their tax advisors regarding the tax considerations of the sale or other disposition of our ADSs or 
ordinary shares under their particular circumstances.
Passive Foreign Investment Company Considerations
A non-U.S. corporation, such as us, will be classified as a PFIC for U.S. federal income tax purposes for any taxable year if either (i) 75% or more of 
its gross income for such year consists of certain types of “passive” income or (ii) 50% or more of the value of its assets (generally determined on the basis 
of a quarterly average) during such year is attributable to assets that produce or are held for the production of passive income. For this purpose, cash and 
assets readily convertible into cash are each categorized as a passive asset and the company’s goodwill and other unbooked intangibles are taken into 
account. Passive income generally includes, among other things, dividends, interest, certain rents and royalties, and gains from the disposition of passive 
assets. In addition, we will be treated as owning a proportionate share of the assets and earning a proportionate share of the income of any other corporation 
in which we own, directly or indirectly, 25% or more (by value) of the stock. 
Based upon the nature and composition of our assets (in particular, the retention of substantial amounts of cash and investments) and income (in 
particular, the generation of interest income and lack of active income), and the market price of our ADSs, we believe that we were a PFIC for the taxable 
year ended December 31, 2024, and we will likely be a PFIC for our current taxable year unless the 

 
134
Table of Contents
market price of our ADSs significantly increases and/or we invest a substantial amount of the cash and other passive assets we hold in assets that produce 
or are held for the production of active income. Because the determination of whether we are a PFIC for a taxable year is fact-intensive and made after the 
close of such taxable year applying principles and methodologies that in some circumstances are unclear and subject to varying interpretations, we cannot 
provide any assurances as to our PFIC status, and our U.S. counsel expresses no opinion with respect to our PFIC status.
If we are a PFIC for any taxable year during which a U.S. Holder holds our ADSs or ordinary shares, we generally will continue to be treated as a 
PFIC for all succeeding years during which such U.S. Holder holds our ADSs or ordinary shares. However, if we cease to be a PFIC, provided that a U.S. 
Holder has not made a mark-to-market election, as described below, such U.S. Holder may avoid some of the adverse effects of the PFIC regime by 
making a “deemed sale” election with respect to the ADSs or ordinary shares, as applicable. If such election is made, the U.S. Holder will be deemed to 
have sold our ADSs or ordinary shares it holds at their fair market value and any gain from such deemed sale would be subject to the rules described in the 
next paragraph. After the deemed sale election, so long as we do not become a PFIC in a subsequent taxable year, the ADSs or ordinary shares with respect 
to which such election was made will not be treated as shares in a PFIC. The rules dealing with deemed sale elections are very complex. Each U.S. Holder 
should consult its tax advisors regarding the possibility and considerations of making a deemed sale election.
If we are classified as a PFIC for any taxable year during which a U.S. Holder holds our ADSs or ordinary shares, and unless the U.S. Holder makes a 
mark-to-market election (as described below), the U.S. Holder will generally be subject to special tax rules, regardless of whether we remain a PFIC, on (i) 
any excess distribution that we make to the U.S. Holder (which generally means any distribution paid during a taxable year to a U.S. Holder that is greater 
than 125 percent of the average annual distributions paid in the three preceding taxable years or, if shorter, the U.S. Holder’s holding period for the ADSs 
or ordinary shares), and (ii) any gain realized on the sale or other disposition (including, under certain circumstances, a pledge) of ADSs or ordinary shares. 
Under such rules:
•
the excess distribution or gain will be allocated ratably over the U.S. Holder’s holding period for the ADSs or ordinary shares;
•
the amount allocated to the current taxable year and any taxable years in the U.S. Holder’s holding period prior to the first taxable year in which 
we are classified as a PFIC, or a pre-PFIC year, will be taxable as ordinary income; and
•
the amount allocated to each prior taxable year, other than a pre-PFIC year, will be subject to tax at the highest tax rate in effect for individuals 
or corporations, as appropriate, for that year, increased by an additional tax equal to the interest on the resulting tax deemed deferred with respect 
to each such taxable year.
If we are a PFIC for any taxable year during which a U.S. Holder holds our ADSs or ordinary shares and any of our subsidiaries is also a PFIC, which 
we refer to as a lower-tier PFIC, such U.S. Holder would be treated as owning a proportionate amount (by value) of the shares of such lower-tier PFIC for 
purposes of the application of these rules. U.S. Holders are urged to consult their tax advisors regarding the application of the PFIC rules to any of our 
subsidiaries.
Certain elections, if available, may be made to result in an alternative to the foregoing rules. A U.S. Holder of “marketable stock” (as defined below) 
in a PFIC may make a mark-to-market election with respect to such stock, provided that such stock is regularly traded on a qualified exchange or other 
market, as defined in the applicable U.S. Treasury regulations. For those purposes, our ADSs, but not our ordinary shares, are listed on the Nasdaq Global 
Market, which is a qualified exchange. The ADSs will be treated as “regularly traded” in any calendar year in which more than a de minimis quantity of the 
ADSs are traded on a qualified exchange on at least 15 days during each calendar quarter (subject to the rule that trades that have as one of their principal 
purposes the meeting of the trading requirement are disregarded). We anticipate that our ADSs should qualify as being regularly traded, but no assurances 
may be given in this regard. If a U.S. Holder makes this election, the holder will generally (i) include as ordinary income for each taxable year that we are a 
PFIC the excess, if any, of the fair market value of ADSs held at the end of the taxable year over the adjusted tax basis of such ADSs and (ii) deduct as an 
ordinary loss the excess, if any, of the adjusted tax basis of the ADSs over the fair market value of such ADSs held at the end of the taxable year, but such 
deduction will only be allowed to the extent of the amount previously included in income as a result of the mark-to-market election. The U.S. Holder’s 
adjusted tax basis in the ADSs would be adjusted to reflect any income or deductible loss resulting from the mark-to-market election. If a U.S. Holder 
makes a mark-to-market election in respect of a corporation classified as a PFIC and such corporation ceases to be classified as a PFIC, the holder will not 
be required to take into account the gain or loss described above during any period that such corporation is not classified as a PFIC. If a U.S. Holder makes 
a mark-to-market election, any gain such U.S. Holder recognizes upon the sale or other disposition of our ADSs in a year when we are a PFIC will be 
treated as ordinary income and any loss will be treated as ordinary loss, but such loss will only be treated as ordinary loss to the extent of the net amount 
previously included in income as a result of the mark-to-market election. If a U.S. Holder makes a mark-to-market election it will be effective for the 
taxable year for which the election is made and all subsequent taxable years unless the ADSs are no longer treated as marketable stock or the IRS consents 
to the revocation of the election.

 
135
Table of Contents
Because a mark-to-market election cannot be made for any lower-tier PFICs that we may own, a U.S. Holder will continue to be subject to the PFIC 
rules with respect to such U.S. Holder’s indirect interest in any investments held by us that are treated as an equity interest in a PFIC for U.S. federal 
income tax purposes.
A “qualified electing fund,” QEF, election, if available and made, also would result in an alternative to the PFIC rules described above. However, we 
do not intend to provide information necessary for U.S. Holders to make QEF elections for the taxable year ended December 31, 2024.
If a U.S. Holder owns our ADSs or ordinary shares during any taxable year that we are a PFIC, the holder must generally file an annual IRS Form 
8621. The PFIC rules are complex, and each U.S. Holder is urged to consult its tax advisor concerning the U.S. federal income tax consequences of 
purchasing, holding and disposing ADSs or ordinary shares if we are or become a PFIC, including the possibility and advisability of making any elections 
under the PFIC rules and the PFIC reporting requirements, in such U.S. Holder’s particular circumstances.
Backup Withholding and Information Reporting
U.S. Holders generally will be subject to information reporting requirements with respect to dividends on ADSs or ordinary shares and proceeds from 
the sale or other disposition of ADSs or ordinary shares that are paid within the United States or through U.S.-related financial intermediaries, unless the 
U.S. Holder is an “exempt recipient.” In addition, U.S. Holders may be subject to backup withholding on such payments, unless the U.S. Holder provides a 
taxpayer identification number on a duly executed IRS Form W-9 or otherwise establishes an exemption. Backup withholding is not an additional tax, and 
the amount of any backup withholding will be allowed as a credit against a U.S. Holder’s U.S. federal income tax liability and may entitle such holder to a 
refund, provided that the required information is timely furnished to the IRS.
Furthermore, certain individual U.S. Holders are required to report information relating to an interest in ADSs or ordinary shares, subject to certain
exceptions (including an exception for ADSs or ordinary shares held in accounts maintained by U.S. financial institutions) by filing IRS Form 8938 
(Statement of Specified Foreign Financial Assets) with their U.S. federal income tax return. U.S. Holders are urged to consult their tax advisors regarding 
their information reporting obligations, if any, with respect to their ownership, and disposition of our ADSs or ordinary shares.
THE DISCUSSION ABOVE IS A SUMMARY OF CERTAIN MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS OF THE 
OWNERSHIP AND DISPOSITION OF OUR ADSs OR ORDINARY SHARES, AND IS NOT TAX ADVICE. U.S. HOLDERS ARE URGED TO 
CONSULT THEIR OWN TAX ADVISORS REGARDING THE U.S. FEDERAL, STATE, AND LOCAL AND NON-U.S. INCOME AND NON-
INCOME TAX CONSIDERATIONS IN THEIR PARTICULAR CIRCUMSTANCES, INCLUDING ANY TAX REPORTING REQUIREMENTS AND 
THE IMPACT OF ANY POTENTIAL CHANGE IN LAW.

ITEM 11. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Market Risks
We are exposed to market risks in the ordinary course of our business. Market risk represents the risk of loss that may impact our financial position 
due to adverse changes in financial market prices and rates. Our market risk exposure is primarily the result of fluctuations in interest rates and foreign 
currency exchange rates.
Interest and Credit Risk
We had cash, cash equivalents, and short-term investments of $173.4 million as of December 31, 2024. Our exposure to interest rate risk primarily 
relates to the interest income generated by excess cash, which is mostly held in interest-bearing bank deposits. Interest-earning instruments carry a degree 
of interest rate risk. We have not been exposed to material risks due to changes in interest rates, and we have not used any derivative financial instruments 
to manage our interest risk exposure. As of December 31, 2024, a hypothetical 10% relative change in interest rates would not have a material impact on 
our consolidated financial statements.
Our credit risk is primarily attributable to the carrying amounts of cash, cash equivalents and short-term investments. The carrying amounts of cash, 
cash equivalents and short-term investments represent the maximum amount of loss due to credit risk. We mainly place or invest cash, cash equivalents and 
short-term investments with financial institutions in the United States. We do not believe that our cash, cash equivalents and short-term investments have 
significant risk of default or illiquidity, and we will continually monitor the credit worthiness of these financial institutions. While we believe our cash, 
cash equivalents and short-term investments do not contain excessive risk, future investments may be subject to adverse changes in market value.
Foreign Exchange Risk
A significant portion of our expenses are denominated in U.S. dollars, a small portion of our expenses are denominated in RMB, and most of our 
assets and liabilities are denominated in U.S. dollars. We do not believe that we currently have any significant direct foreign exchange risk and have not 
used any derivative financial instruments to hedge exposure to such risk. Although our exposure to foreign exchange risks should be limited in general, the 
value of our investors’ investments in our ADSs will be affected by the exchange rate between U.S. dollar and other currencies of the jurisdictions where 
our contractors locate, because we need to incur expenses in local currencies, while our ADSs will be traded in U.S. dollars.
Other currencies have fluctuated against the U.S. dollar, at times significantly and unpredictably. It is difficult to predict how market forces or 
government policies may impact the exchange rate between the U.S. dollar and other currencies in the future.
To the extent that we need to convert U.S. dollars into other currencies for our operations, appreciation of these currencies against the U.S. dollar 
would have an adverse effect on the converted amount of the other currencies. Conversely, if we decide to convert other currencies into U.S. dollars for the 
purpose of making payments for dividends on our ordinary shares or ADSs or for other business purposes, appreciation of the U.S. dollar against these 
currencies would have a negative effect on the U.S. dollar amounts available to us. A decline in the value of other currencies against the U.S. dollar could 
reduce the U.S. dollar equivalent of our financial results, the value of our investors’ investments in our company and the dividends that we may pay in the 
future, if any, all of which may have a material adverse effect on the prices of our ADS.

American Depositary Shares
Citibank, as depositary for our ADSs, registers and delivers the ADSs. Each ADS represents an ownership interest in a designated number of ordinary 
shares which we deposit with the custodian, as agent of the depositary. Each 10 ADSs represents 23 ordinary shares. 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). The depositary’s office is located at 388 
Greenwich Street, New York, New York 10013.
A deposit agreement among ourselves, the depositary and our investor as ADR holders, and all beneficial owners of an interest in the ADSs evidenced 
by ADRs from time to time sets out the ADR holder rights as well as rights and obligations of the depositary. New York law governs the deposit agreement 
and the ADRs. A copy of the deposit agreement is incorporated by reference as an exhibit to this Annual Report.
Fees and Charges Our ADS Holders May Have to Pay

See “Item 10. Additional Information—B. Memorandum and Articles of Association” for a description of the rights of securities holders, which 
remain unchanged.
ITEM 15. CONTROLS AND PROCEDURES
Evaluation of Disclosure Controls and Procedures
Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has performed an evaluation of the effectiveness 
of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as 
of the end of the period covered by this report, as required by Rule 13a-15(b) under the Exchange Act.
Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of December 31, 2024, our disclosure 
controls and procedures were ineffective due to material weaknesses in internal control over financial reporting as described below.
Management’s Annual Report on Internal Control over Financial Reporting
Management is responsible for establishing and maintaining adequate internal control over financial reporting. Our management, with the 
participation of our Chief Executive Officer and Chief Financial Officer, has assessed the effectiveness of our internal control over financial reporting as of 
December 31, 2024. Our management’s assessment was based on the framework in “Internal Control — Integrated Framework (2013)” (“2013 
framework”), issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). Based on this assessment, our management 
concluded that, as of December 31, 2024, our internal control over financial reporting was ineffective based on the criteria in the 2013 framework issued by 
the COSO due to the existence of the material weaknesses described below. 
A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable 
possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.
In connection with the preparation of the financial statements for this Annual Report on Form 20-F, we identified material weaknesses whereby we 
did not design and maintain information technology (“IT”) general controls for information systems that are relevant to the preparation of our financial 
statements. Specifically, we did not design and maintain: (i) program change management controls to ensure that information technology program and data 
changes are identified, tested, authorized and implemented appropriately; (ii) user access controls to ensure appropriate segregation of duties and to 
adequately restrict user and privileged access to appropriate personnel; (iii) computer operations controls to ensure that processing and transfer of data, and 
data backups and recovery are monitored; and (iv) program development controls to ensure that new software development is tested, authorized and 
implemented appropriately. These material weaknesses did not result in a misstatement to the consolidated financial statements; however, they could result 
in misstatements impacting the annual or interim consolidated financial statements that would result in a material misstatement to the annual or interim 
consolidated financial statements that would not be prevented or detected.
The effectiveness of our internal control over financial reporting as of December 31, 2024 has been audited by PricewaterhouseCoopers LLP, an 
independent registered public accounting firm, as stated in their report which appears in our consolidated financial statements included elsewhere in this 
annual report.
Remediation Activities
Our management has undergone a comprehensive review of these material weaknesses and has begun designing and implementing controls to 
remediate each material weakness. The following actions have been taken or will be taken by us to remediate identified material weaknesses:

 
141
Table of Contents
•
Design and implement controls over program change management and the review and update of user access rights and privileges. 
•
Design and implement controls to formalize roles and review responsibilities in order to formalize and implement controls over segregation 
of duties across key financial systems.
•
Design and implement computer operation and program development controls to ensure data integrity and that new software development is 
tested, authorized, and implemented appropriately.
•
Engage our third-party IT services provider to assist with the execution of the controls listed above, and further involve our internal audit 
function to test each control’s operating effectiveness. 
We believe the foregoing efforts, when fully implemented and operational, will effectively remediate the material weaknesses described above and 
strengthen our internal control over financial reporting. As we continue to evaluate and work to improve our internal control over financial reporting, we 
may take additional measures to address these control deficiencies or modify the remediation plans described above. We cannot assure our investors, 
however, when we will remediate such weaknesses, nor can we be certain of whether additional actions will be required.
Changes in Internal Control over Financial Reporting
There were changes to our internal control over financial reporting that occurred during the period covered by this annual report on Form 20-F that 
have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. We divested our Greater China assets 
and business operations and transitioned operations to the United States. The transition to the United States led to significant organizational changes that 
materially affected our control environment. During the year new systems were implemented, including our general ledger and procurement systems, 
leading to the establishment and implementation of new internal controls. Furthermore, the transition to U.S. operations resulted in new staff in key areas 
and required additional training over internal controls. These factors, among others, resulted in changes to our internal control over financial reporting.
Inherent Limitations on the Effectiveness of Controls
Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls or our internal 
control over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only 
reasonable, not absolute, assurance that the control system’s objectives will be met. The design of a control system must reflect the fact that there are 
resource constraints, and the benefits of controls must be considered relative to their costs. Further, because of the inherent limitations in all control 
systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and 
instances of fraud, if any, within the Company have been detected. Also, projections of any evaluation of effectiveness to future periods are subject to the 
risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may 
deteriorate.
ITEM 16A. AUDIT COMMITTEE FINANCIAL EXPERT
Our board of directors has determined that Conor Chia-hung Yang, a member of our audit committee and independent director (under the standards

expert. See “Item 6. Directors, Senior Management and Employees—A. Directors and Senior Management” for Mr. Yang’s experience and qualifications.

ITEM 16E. PURCHASES OF EQUITY SECURITIES BY THE ISSUER AND AFFILIATED PURCHASERS
On August 17, 2023, we announced that our board of directors had authorized a new stock repurchase program, which we refer to as the 2023 Stock 
Repurchase Program, under which we may repurchase up to $40 million of our ordinary shares in the form of ADSs for a 12-month period. The 2023 Stock 
Repurchase Program became effective on August 15, 2023. Approximately $5.2 million worth of ADSs were repurchased under the share repurchase 
program, which was in effect from August 15, 2023 through August 14, 2024. Our board of directors has not, and does not intend, to renew the stock 
repurchase program.
In 2024, we purchased an aggregate of 179,656 ADSs under our 2023 Stock Repurchase Program. The table below is a summary of the shares 
repurchased by us during the year ended December 31, 2024. All shares were repurchased in the open market pursuant to the authorized stock repurchase 
program. No other share repurchases occurred during 2024.

ITEM 16G. CORPORATE GOVERNANCE
As a Cayman Islands company listed on Nasdaq, we are subject to the Nasdaq corporate governance listing standards. However, Nasdaq rules permit a 
foreign private issuer like us to follow the corporate governance practices of its home country. Certain corporate governance practices in the Cayman 
Islands, which is our home country, may differ significantly from the Nasdaq corporate governance listing standards.
In lieu of (i) the requirements of Rule 5605(d) that a compensation committee be comprised solely of independent directors, (ii) the requirements of 
Rule 5605(e) that a nominating committee be comprised solely of independent directors, (iii) the requirements of Rule 5620(a) that each Nasdaq-listed 
company should hold an annual general meeting of shareholders no later than one year after the end of its fiscal year-end, and (iv) the requirements of Rule 
5635(c) of the Nasdaq Rules that shareholder approval be required prior to the issuance of securities when a stock option or purchase plan is to be 
established or materially amended or other equity compensation arrangement made or materially amended, pursuant to which stock may be acquired by 
officers, directors, employees, or consultants, we have followed and intend to continue to follow our home country practices with respect to the board 
committees, annual shareholders meeting as well as the approval for adoption and material amendment to our equity-based compensation plans. If we 
choose to follow any other home country practice in the future, our shareholders may be afforded less protection than they otherwise would under the 
Nasdaq corporate governance listing standards applicable to U.S. domestic issuers. See “Item 3. Key Information—D. Risk Factors—General Risks 
Related to Our ADSs—We are a foreign private issuer within the meaning of the rules under the Exchange Act, and as such we are exempt from certain 
provisions applicable to U.S. domestic public companies.”

ITEM 16J. INSIDER TRADING POLICIES
We have adopted an insider trading policy which was most recently amended and restated by our board of directors in April 2024 to align with our 
current business operations. The policy governs the purchase, sale, and/or other dispositions of our securities by our directors, officers, and employees, to 
promote compliance with insider trading laws, rules and regulations, and Nasdaq listing standards applicable to us. Our insider trading policy is filed as 
Exhibit 11.2 to this Form 20-F.
ITEM 16K. CYBERSECURITY
Risk Management and Strategy
We have implemented comprehensive cybersecurity risk assessment procedures to ensure effectiveness in cybersecurity management, strategy and 
governance and reporting cybersecurity risks. We have also integrated cybersecurity risk management into our overall enterprise risk management system. 
We are committed to safeguarding our systems and data. Our approach to managing internal and external cybersecurity risks and safeguarding 
sensitive data is multi-faceted, involving technological safeguards, procedural protocols, a rigorous program of surveillance on our corporate network, 
continuous testing of aspects of our security posture internally and with third-party consultants or collaborators, a solid incident response framework and 
regular cybersecurity training sessions for our employees. Our IT department is actively engaged in continuous monitoring of the performance of our 
infrastructure to ensure prompt identification and response to potential issues, including potential cybersecurity threats. We use third-party service 
providers to assist us from time to time to identify, assess, and manage material risks from cybersecurity threats, including for example: professional 
services firms, cybersecurity consultants and cybersecurity software providers.
As of the date of this annual report, we have not experienced any material cybersecurity incidents or identified any material cybersecurity threats that 
have affected or are reasonably likely to materially affect us, our business strategy, results of operations or financial condition.

Table of Contents
Governance
Our nominating and corporate governance committee of our board of directors is responsible for overseeing our cybersecurity risk management and is 
informed on risks from cybersecurity threats. The nominating and corporate governance committee shall review, approve and maintain oversight of the 
disclosure (i) on Form 6-K for material cybersecurity incidents (if any) and (ii) related to cybersecurity matters in the periodic reports (including annual 
report on Form 20-F) of our company. 
On the management level, our Chief Executive Officer and Chief Financial Officer, collectively referred as the Cybersecurity Risk Management 
Officers, are responsible for assessing, identifying and managing material risks from cybersecurity threats to our company and monitoring the prevention, 
detection, mitigation and remediation of material cybersecurity incidents. Our Cybersecurity Risk Management Officers report to our nominating and 
corporate governance committee (i) periodically regarding their assessment, identification and management on material risks from cybersecurity threats in 
the ordinary course of our business operations and (ii) on disclosure concerning cybersecurity matters in our Form 6-K for material cybersecurity incidents 
(if any) and our annual report on Form 20-F.
If a cybersecurity incident occurs, our Cybersecurity Risk Management Officers will promptly organize relevant personnel for internal assessment 
and, depending on the situation, seek the opinions of external experts and legal advisors. If it is determined that the incident could potentially be a material 
cybersecurity event, our Cybersecurity Risk Management Officers will promptly report the incident and relevant assessment results to our nominating and 
corporate governance committee, who will decide on the relevant response measures and whether any disclosure is necessary. If such disclosure is 
determined to be necessary, our Cybersecurity Risk Management Officers shall promptly prepare disclosure materials for review and approval by our 
nominating and corporate governance committee before it is disseminated to the public.

Report of Independent Registered Public Accounting Firm
To the Board of Directors and Shareholders of I-MAB
Opinions on the Financial Statements and Internal Control over Financial Reporting
We have audited the accompanying consolidated balance sheet of I-MAB and its subsidiaries (the "Company") as of December 31, 2024, and the related
consolidated statements of comprehensive loss, of changes in shareholders' equity and of cash flows for the year then ended, including the related notes 
(collectively referred to as the "consolidated financial statements"). We also have audited the Company's internal control over financial reporting as of 
December 31, 2024, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations 
of the Treadway Commission (COSO).
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of
December 31, 2024, and the results of its operations and its cash flows for the year then ended in conformity with accounting principles generally accepted 
in the United States of America. Also in our opinion, the Company did not maintain, in all material respects, effective internal control over financial 
reporting as of December 31, 2024, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO because material 
weaknesses in internal control over financial reporting existed as of that date as the Company did not design and maintain effective information technology 
general controls for information systems that are relevant to the preparation of the financial statements; specifically, the Company did not design and 
maintain effective (i) program change management controls, (ii) user access controls, (iii) computer operations controls, and (iv) program development 
controls.
A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility 
that a material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis. The material weaknesses 
referred to above are described in Management’s Annual Report on Internal Control over Financial Reporting appearing under Item 15. We considered 
these material weaknesses in determining the nature, timing, and extent of audit tests applied in our audit of the 2024 consolidated financial statements, and 
our opinion regarding the effectiveness of the Company’s internal control over financial reporting does not affect our opinion on those consolidated 
financial statements.
Basis for Opinions
The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, 
and for its assessment of the effectiveness of internal control over financial reporting, included in management's report referred to above. Our responsibility 
is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our 
audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be 
independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and 
Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable 
assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective 
internal control over financial reporting was maintained in all material respects.
Our audit of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial 
statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, 
evidence regarding the amounts and disclosures in the consolidated financial statements. Our audit also included evaluating the accounting principles used 
and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal 
control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness 
exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing 
such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinions.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting 
and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control 
over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly 
reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit
preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are 
being made only in 

 
F-3
Table of Contents
accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely 
detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of 
effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of 
compliance with the policies or procedures may deteriorate.
Critical Audit Matters
The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was 
communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated 
financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not 
alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, 
providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Fair Value of the Investments in TJBio Hangzhou
As described in Note 7 to the consolidated financial statements, the Company’s fair value of the investments in available-for-sale debt securities related to
TJBio Hangzhou (“investments in TJBio Hangzhou”) was $30.8 million as of December 31, 2024. The Company’s investments in TJBio Hangzhou’s 
Series A, B and C preferred shares are contingently redeemable as TJBio Hangzhou's redemption obligation is only satisfied upon a future liquidity event 
by a specified date, which is not within the control of the investor or the issuer. As such, management accounted for the investments in TJBio Hangzhou as 
available-for-sale debt securities which are reported at fair value at each reporting period. The fair value of the investments in TJBio Hangzhou was 
determined by management using a backsolve method based on the recent Series C financing of TJBio Hangzhou and adjusted by applying a change in the 
movement of a selected set of comparable companies and biotech indices. This value was then allocated toward TJBio Hangzhou’s Series A, B, and C 
capital structure using an option pricing method, and a waterfall approach based on the order of liquidation preferences of the Series A, B, and C shares 
relative to one another. The significant assumptions and inputs used by management in the option pricing method included an equity market adjustment, 
expected time to change in control (year), estimated volatility, and a risk free rate. 
The principal considerations for our determination that performing procedures relating to the fair value of the investments in TJBio Hangzhou is a critical 
audit matter are (i) the significant judgment by management when developing the fair value estimate of the investments in TJBio Hangzhou; (ii) a high
degree of auditor judgment, subjectivity, and effort in evaluating management’s significant assumptions related to the equity market adjustment, estimated 
volatility, and risk free rate; and (iv) the audit effort involved the use of professionals with specialized skill and knowledge. 
Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated 
financial statements. These procedures included testing the effectiveness of controls relating to management’s estimate of the fair value, including controls 
over management’s significant assumptions. These procedures also included, among others (i) reading the Series C shareholder agreement; (ii) testing 
management’s process for developing the fair value estimate of the investments in TJBio Hangzhou; (iii) testing the completeness and accuracy of 
underlying data used in the backsolve method, option pricing method, and waterfall approach; and (iv) evaluating the reasonableness of the significant 
assumptions used by management related to the equity market adjustment, estimated volatility, and risk free rate. Evaluating management’s assumption 
related to the equity market adjustment involved considering (i) the consistency with external information about TJBio Hangzhou and external market and 
industry data and (ii) whether the assumption was consistent with evidence obtained in other areas of the audit. Professionals with specialized skill and 
knowledge were used to assist in evaluating the (i) appropriateness of the backsolve method, option pricing method, and waterfall approach and (ii) the 
reasonableness of the equity market adjustment, estimated volatility, and risk free rate assumptions.

To the Board of Directors and Shareholders of I-Mab
 
Opinion on the Financial Statements 
 
We have audited the consolidated balance sheet of I-Mab and its subsidiaries (the “Company”) as of December 31, 2023, and the related consolidated 
statements of comprehensive loss, of changes in shareholders’ equity and of cash flows for each of the two years in the period ended December 31, 2023, 
including the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present 
fairly, in all material respects, the financial position of the Company as of December 31, 2023, and the results of its operations and its cash flows for each 
of the two years in the period ended December 31, 2023 in conformity with accounting principles generally accepted in the United States of America.    
 
Basis for Opinion 
 
These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s 
consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board 
(United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the 
applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.  
 
We conducted our audits of these consolidated financial statements in accordance with the standards of the PCAOB. Those standards require that we plan 
and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to 
error or fraud.
 
Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or 
fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and 
disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by 
management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis 
for our opinion.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
(All amounts in thousands, except for share and per share data, unless otherwise noted)
1. PRINCIPAL ACTIVITIES AND ORGANIZATION
I-Mab (the “Company”) was incorporated in the Cayman Islands on June 30, 2016 as an exempted company with limited liability under the Companies Act 
of the Cayman Islands. On January 17, 2020, the Company became listed on the Nasdaq Global Market in the United States. The Company and its 
subsidiaries (together the “Group”) are principally engaged in the development of precision immuno-oncology agents for the treatment of cancer and 
principally operate in the United States.
On February 6, 2024, the Group entered into definitive agreements with I-Mab Biopharma (Hangzhou) Co., Ltd. (later renamed TJ Biopharma (Hangzhou) 
Co., Ltd. and referred to herein as “TJBio Hangzhou”) and a group of China-based investors. Pursuant to the definitive agreements, the Group transferred 
100% of the outstanding equity interest in I-Mab Biopharma Co., Ltd (later renamed to TJ Biopharma (Shanghai) Co. Ltd. and referred to herein as “TJBio 
Shanghai”), a former wholly-owned subsidiary of the Company that operated the Company’s business in China to TJ Biopharma (Hangzhou) Co., Ltd., 
collectively known as “TJ Biopharma” after the completion of the equity transfer transaction, for an aggregate consideration of the RMB equivalent of up 
to $80 million, contingent on TJ Biopharma’s achievement of certain future regulatory and sales-based milestone events as well as royalties. The 
transaction was completed on April 2, 2024. For details of the transaction please refer to Note 3 – Disposal of TJBio Shanghai.
Unless otherwise indicated, the information in the notes to the Consolidated Financial Statements refers only to I-Mab continuing operations.

2. PRINCIPAL ACCOUNTING POLICIES
Basis of presentation
The accompanying consolidated financial statements of the Group have been prepared in accordance with the accounting principles generally accepted in 
the United States of America (“U.S. GAAP”).
Significant accounting policies followed by the Group in the preparation of the accompanying consolidated financial statements are summarized below.
The accompanying consolidated financial statements reflect the accounts of the Company and all of its subsidiaries in which a controlling interest is 
maintained. All inter-company balances and transactions have been eliminated in consolidation.
The Group consolidates entities in which it has a controlling financial interest based on either the variable interest entity (“VIE”) or voting interest model. 
The Group is required to first apply the VIE model to determine whether it holds a variable interest in an entity, and if so, whether the entity is a VIE. If the 
Group determines it does not hold a variable interest in a VIE, it then applies the voting interest model. Under the voting interest model, the Group 
consolidates an entity when it holds a majority voting interest in an entity.
The Company accounts for investments in which it has significant influence but not a controlling financial interest using the equity method of accounting
(see Note 7 – Investments and put right liabilities).

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
(All amounts in thousands, except for share and per share data, unless otherwise noted)
F-11
Table of Contents
VIE Model
An entity is considered to be a VIE if any of the following conditions exist: (a) the total equity investment at risk is not sufficient to permit the entity to 
finance its activities without additional subordinated financial support, (b) the holders of the equity investment at risk, as a group, lack either the direct or 
indirect ability through voting rights or similar rights to make decisions that have a significant effect on the success of the entity or the obligation to absorb 
the entity’s expected losses or right to receive the entity’s expected residual returns, or (c) the voting rights of some equity investors are disproportionate to 
their obligation to absorb losses of the entity, their rights to receive returns from an entity, or both and substantially all of the entity’s activities either 
involve or are conducted on behalf of an investor with disproportionately few voting rights.
Under the VIE model, limited partnerships are considered VIE unless the limited partners hold substantive kick-out or participating rights over the general 
partner. The Group consolidates entities that are VIEs when the Group determines it is the primary beneficiary. Generally, the primary beneficiary of a VIE 
is a reporting entity that has (a) the power to direct the activities that most significantly affect the VIE’s economic performance, and (b) the obligation to 
absorb losses of, or the right to receive benefits from, the VIE that could potentially be significant to the VIE.
As of December 31, 2024, the Group did not have any entity subject to the consolidation guidance under the VIE model.
Use of estimates
The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that 
affect the reported amounts of assets and liabilities and the disclosures of contingent assets and liabilities at the date of the consolidated financial statements 
and the reported amounts of revenues and expenses during the reporting period. Estimates are used when accounting for amounts recorded in connection 
with acquisitions, including initial fair value determinations of assets and liabilities as well as subsequent fair value measurements. Additionally, estimates 
are used in determining items such as fair value measurements of investments in available-for-sale debt securities, put right liabilities, impairment of other 
receivables, long-lived assets, useful lives of property, equipment and software, recognition of right-of-use assets and lease liabilities, accrued research and 
development expenses, cost-to-cost measure of progress for over time performance obligations, variable consideration in collaboration revenue 
arrangements, valuation of share-based compensation arrangements, deferred tax assets valuation allowances and provision for ongoing litigation. 
Management bases the estimates on historical experience, known trends and various other assumptions that are believed to be reasonable, the results of 
which form the basis for making judgments about the carrying values of assets and liabilities. Actual results could differ from those estimates.
Fair value measurements
Financial assets and liabilities of the Group are primarily comprised of cash and cash equivalents, short-term investments, investments in available-for-sale 
debt securities, other receivables, accruals and other payables, contract liabilities, put right liabilities and other non-current liabilities. As of December 31, 
2024 and 2023, except for investments in available-for-sale debt securities and put right liabilities, the carrying values of these financial assets and 
liabilities approximated their fair values because of their generally short maturities. The Group reports investments in available-for-sale debt securities and 
put right liabilities at fair value at each balance sheet date. The changes in fair value of the put right liabilities are reflected in the consolidated statements of 
comprehensive loss. The unrealized holding gains and losses of the investments in available-for-sale debt securities are reflected as a component of 
accumulated other comprehensive loss.
The Group measures its financial assets and liabilities using inputs from the following three levels of the fair value hierarchy:
Level 1 inputs are unadjusted quoted prices in active markets for identical assets that the Group’s management has the ability to access at the 
measurement date.
Level 2 inputs include quoted prices for similar assets in active markets, quoted prices for identical or similar assets in markets that are not 
active, inputs other than quoted prices that are observable for the asset (i.e., interest rates, yield curves, etc.), and inputs that are derived 
principally from or corroborated by observable market data by correlation or other means (market corroborated inputs).

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
(All amounts in thousands, except for share and per share data, unless otherwise noted)
F-12
Table of Contents
Level 3 includes unobservable inputs that reflect the management’s best estimate of assumptions that market participants would use in pricing 
the asset. The Group’s management develops these inputs based on the best information available, including their own data.
Assets and liabilities measured at fair value on a recurring basis
The Group measures its investments in available-for-sale debt securities and put right liabilities at fair value on a recurring basis. As the Group’s 
investments in available-for-sale debt securities and put right liabilities are not traded in an active market with readily observable prices, the Group uses 
significant unobservable inputs to measure the fair value of investments in available-for-sale debt securities and put right liabilities. These instruments are 
categorized in the Level 3 valuation hierarchy based on the significance of unobservable factors in the overall fair value measurement.
The following table summarizes the Group’s financial assets and liabilities measured and recorded at fair value on a recurring basis as of December 31, 
2024 and 2023:

Foreign currency translation
Effective April 2, 2024, the Group changed its reporting currency from Chinese Renminbi (“RMB”) to United States Dollar (“U.S. Dollar”). The change 
was made to align the reporting currency with the underlying operations of the Group as the majority of its expenses, assets, liabilities and shareholders' 
equity were denominated in the U.S. Dollar upon the completion of its Greater China assets and business operations divestiture on April 2, 2024. The U.S. 
Dollar is the functional currency of the Group’s entities incorporated in

the transaction dates. Assets and liabilities denominated in other than the functional currencies are translated at the balance sheet date exchange rate. The 
resulting exchange differences are recorded in foreign currency translation adjustments in the consolidated statements of comprehensive loss.
The consolidated financial statements of the Group are translated from the functional currency to the reporting currency, U.S. Dollar. Assets and liabilities 
of the Company’s subsidiaries are translated into U.S. Dollar using the exchange rate in effect at each balance sheet date. Income and expenses are 
translated at the average exchange rates prevailing for the year. Foreign currency translation adjustments arising from these are reflected in the accumulated 
other comprehensive loss.
Cash and cash equivalents
Cash and cash equivalents consist of cash on hand and bank deposits, which are unrestricted to withdrawal and use. The Group considers all highly liquid 
investments with an original maturity date of three months or less at the date of purchase to be cash equivalents.
 
Short-term investments
Short-term investments represent certificates of deposits held in commercial banks with a fixed interest rate over three months and within one year. The 
certificates of deposits are accounted for as held-to-maturity investments carried at amortized cost. 
Property, equipment and software 
Property, equipment and software are stated at cost less accumulated depreciation and amortization. Depreciation and amortization is computed using the 
straight-line method over the following estimated useful lives, taking into account of any estimated residual value:
 
Laboratory equipment
3 to 10 years
Computer hardware
1 to 5 years
Software
1 to 5 years
Office furniture and equipment
5 years
Leasehold improvements
Lesser of useful life or lease term
 
The Group recognizes the gain or loss on the disposal of property, equipment and software in the consolidated statements of comprehensive loss.
Impairment of long-lived assets
Long-lived assets, such as property, plant, and software subject to amortization, are reviewed for impairment whenever events or changes in circumstances 
indicate that the carrying amount of an asset may not be recoverable. If circumstances require a long-lived asset or asset group be tested for possible 
impairment, the Group first compares undiscounted cash flows expected to be generated by that asset or asset group to its carrying amount. If the carrying 
amount of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the 
carrying amount exceeds its fair value. Fair value is determined through various valuation techniques including discounted cash flow models, quoted 
market values and third-party independent appraisals, as considered necessary. For the year ended December 31, 2024, the Group recognized $1.2 million 
of impairment related to long-lived assets held for sale. There was no impairment of the value of the Group’s long-lived assets for the years ended 
December 31, 2023 and 2022.
Goodwill
Goodwill is an asset representing the future economic benefits arising from other assets acquired in a business combination that are not individually
identified and separately recognized. The Group allocates the cost of an acquired entity to the assets acquired and liabilities assumed based on their 
estimated fair values at the date of acquisition. The excess of the purchase price for acquisitions over the fair value of the net assets acquired, including 
other intangible assets, is recorded as goodwill. Goodwill is not amortized, but impairment

of goodwill is tested on at least an annual basis or whenever events or changes in circumstances indicate that the carrying value of the reporting unit may 
exceeds its fair value.
The Group first assesses qualitative factors to determine whether it is more likely than not that the fair value of the Group’s reporting unit is less than its 
carrying amount, including goodwill. The qualitative assessment includes the Group’s evaluation of relevant events and circumstances affecting the 
Group’s single reporting unit, including macroeconomic, industry, market conditions and the Group’s overall financial performance. If qualitative factors 
indicate that it is more likely than not that the Group’s reporting unit’s fair value is less than its carrying amount, then the Group will perform the 
quantitative impairment test by comparing the reporting unit’s carrying amount, including goodwill, to its fair value. If the carrying amount of the reporting 
unit exceeds its fair value, an impairment loss will be recognized in an amount equal to that excess. For the year ended December 31, 2023, as a result of 
the impairment assessment, the Group identified that the carrying amount of the Group's single reporting unit had exceeded its fair value, and therefore 
recognized goodwill impairment of $23.0 million. The Group did not recognize any goodwill impairment for the years ended December 31, 2024 and 2022. 
Long-term investments
The Group's long-term investments include investments in TJ Biopharma’s contingently redeemable preferred shares that feature redemption rights upon a 
future liquidity event by a specified date which are not within the control of the investor or the issuer. The investment is accounted for as an available-for-
sale debt security in accordance with Accounting Standard Codification (“ASC”) 320, Investments—Debt Securities. The investments are reported at fair 
value with the related unrealized gains and losses included as a component of accumulated other comprehensive loss. For investments in an unrealized loss 
position, the Group assess whether it intends to sell the security or will more likely than not be required to sell the security before recovery of its amortized 
cost basis. If either of the criteria regarding intent or requirement to sell is met, the security's amortized cost basis is written down to fair value and the 
impairment is recognized in other income (expense), net in the consolidated statements of comprehensive loss. If the security does not meet the 
aforementioned intent or requirement to sell criteria, the Group evaluates whether the decline in fair value is due to credit-related factors. Any impairment 
due to credit-related losses are recorded as an allowance for credit losses and are included in other income (expense), net in the consolidated statements of 
comprehensive loss. 
The Group had equity investments prior to the divestiture of its Greater China assets and business operations in an affiliate in which it did not have a 
controlling financial interest, but had the ability to exercise significant influence over the operating and financial policies of the investee. The investment 
was accounted for using the equity method of accounting in accordance with ASC 323, Investments—Equity Method and Joint Ventures (“ASC 323”). 
Under the equity method, the Group initially recorded its investments at fair value. The Group subsequently adjusted the carrying amount of the investment 
to recognize the Group’s proportionate share of the equity investee’s net income or loss after the date of investment. When the liquidation rights and 
priorities as defined by an equity investment agreement differ from what is reflected by the underlying percentage ownership interests, applying the 
percentage ownership interest to U.S. GAAP net income in order to determine earnings or losses does not accurately represent the income allocation and 
cash flow distributions that will ultimately be received by the investors. As such, for this type of investments, the Group used the Hypothetical Liquidation 
at Book Value (“HLBV”) method for allocating earnings or losses of the equity method investee. The HLBV method is considered as a balance sheet 
approach. Specifically, a calculation is prepared at each balance sheet date to determine the amount that the Group would receive if an equity investment 
entity were to liquidate all of its assets (as valued in accordance with U.S. GAAP) and distribute that cash to the investors based on the contractually 
defined liquidation priorities. The difference between the calculated liquidation distribution amounts at the beginning and the end of the reporting period, 
after adjusting for capital contributions and distributions, is the Group’s share of the earnings or losses from the equity investment for the period.
As it relates to the share-based compensation awarded by an equity method investee to its own employees, the Group recognized its proportionate share of 
the compensation expense over the vesting period, included in the equity in loss of affiliates in the consolidated statements of comprehensive loss. As it 
relates to the share-based compensation awarded by the Group to the equity method investee employees that are based on the Group’s stock, when the other 
investors did not provide proportionate value to the investee or the Group did not receive any consideration, the Group expensed the entire cost associated 
with the award in the same period the costs were recognized by the investee, to the extent that the Group’s claim on the investee’s book value has not been 
increased. The expenses recognized by the Group was included in the equity in loss of affiliate in the consolidated statements of comprehensive loss. The 
Group discontinued applying the equity method in 2023 when the carrying amount of the investment was reduced to zero.
The Group evaluated the equity method investment for impairment under ASC 323. An impairment loss on the equity method investments is recognized in 
losses when the decline in value is determined to be other-than-temporary. No impairment charge was recognized for the years ended December 31, 2023 
and 2022 related to the equity method investments.

Revenue recognition
The Group adopted ASC 606, Revenue from Contracts with Customers (“ASC 606”) for all periods presented. Consistent with the criteria of ASC 606, the 
Group recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity 
expects to receive in exchange for those goods or services.
Under ASC 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration 
that the entity expects to receive in exchange for those goods or services. An entity performs the following five steps to account for the arrangements that it 
determines are within the scope of ASC 606: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) 
determine the transaction price, including variable consideration, if any; (iv) allocate the transaction price to the performance obligations in the contract; 
and (v) recognize revenue when (or as) the entity satisfies a performance obligation.
Once a contract is determined to be within the scope of ASC 606 at contract inception, the Group reviews the contract to determine which performance 
obligations it must deliver and which of these performance obligations are distinct. The Group recognizes as revenue the amount of the transaction price 
that is allocated to each performance obligation when that performance obligation is satisfied or as it is satisfied.
Collaboration revenue
At contract inception, the Group analyzes its collaboration arrangements to assess whether they are within the scope of ASC 808, Collaborative 
Arrangements (“ASC 808”) to determine whether such arrangements involve joint operating activities performed by parties that are both active participants 
in the activities and exposed to significant risks and rewards dependent on the commercial success of such activities. For collaboration arrangements within 
the scope of ASC 808 that contain multiple elements, the Group first determines if the collaboration is deemed to be within the scope of ASC 808. For any 
units of account that are reflective of a vendor-customer relationship those units of account are accounted for within the scope of ASC 606. For any units of 
account that are not accounted for under ASC 606 and therefore accounted for pursuant to ASC 808, an appropriate recognition method is determined and 
applied consistently.
The Group’s collaborative arrangements may contain more than one unit of account, or performance obligation, such as grant of licenses of intellectual 
property rights, promises to provide research and development services and other deliverables. The collaborative arrangements do not include a right of 
return for any deliverable. When multiple units of account or performance obligations are identified within the arrangements, the Group must develop 
assumptions that require judgment to determine the stand-alone selling price for each performance obligation identified in the contract. In developing the 
stand-alone selling price for a performance obligation, the Group considers competitor pricing for a similar or identical product, market awareness of and 
perception of the product, expected product life and current market trends. In general, the consideration allocated to each performance obligation is 
recognized when the respective obligation is satisfied either by delivering a good or providing a service, limited to the consideration that is not constrained.
Licenses of Intellectual Property: Upfront non-refundable payments for licensing the Group’s intellectual property are evaluated to determine if the license 
is distinct from the other performance obligations identified in the arrangement. For the license that is determined to be distinct, the Group recognizes 
revenues in the amount of non-refundable, upfront fees allocated to the license at a point in time, upon which the license is transferred to the licensee and 
the licensee is able to use and benefit from the license.
Research and Development Services: The portion of the transaction price allocated to the performance obligations of research and development services is 
deferred and recognized as revenue over time as delivery or performance of such services is provided to the Group’s customers occurs.
Milestone Payments: At the inception of each arrangement that includes development, commercialization, and regulatory milestone payments, the Group (i) 
evaluates whether the achievement of milestones are considered probable and to the extent that a significant reversal of cumulative revenue would not 
occur in future periods, and (ii) estimates the amount to be included in the transaction price using the most likely amount method. The transaction price is 
then allocated to each performance obligation on a relative stand-alone selling price basis, for which the Group recognizes revenue as or when the 
performance obligations under the contract are satisfied. At the end of each subsequent reporting period, the Group re-evaluates the probability of 
achieving such development milestones and any related constraint, and if necessary, adjusts the estimate of the overall transaction price. Any resulting 
adjustment is recorded on a cumulative catch-up basis, which would affect the Group’s reported revenues and earnings in the period of the adjustment.

Table of Contents
Royalties: For arrangements that include sales-based royalties, including milestone payments based on the level of sales, and the license is deemed to be the 
predominant item to which the sales-based royalties or milestone payments relate, the Group recognizes revenue at the later of (i) when the related sales 
occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied).
Contract assets and liabilities
Contract assets primarily represent revenue earnings over time that are not yet billable based on the terms of the contracts.
Contract liabilities consist of fees invoiced or paid by the Group’s customers for which the associated performance obligations have not been satisfied and 
revenue has not been recognized based on the Group’s revenue recognition criteria described above.
Contract assets and contract liabilities are reported in a net position on an individual contract basis at the end of each reporting period. Contract assets are 
classified as current in the consolidated balance sheet when the Group expects to complete the related performance obligations and invoice the customers 
within one year of the balance sheet date, and as long-term when the Group expects to complete the related performance obligations and invoice the 
customers more than one year out from the balance sheet date. Contract liabilities are classified as current in the consolidated balance sheet when the 
revenue recognition associated with the related customer payments and invoicing is expected to occur within one year of the balance sheet date and as long-
term when the revenue recognition associated with the related customer payments and invoicing is expected to occur in more than one year from the 
balance sheet date.
Cost-to-cost measure of progress for over time performance obligations
Under certain licensing and collaboration arrangement entered into with a business partner, the Group recognized revenue using the cost-to-cost measure. 
Under the cost-to-cost measure of progress method, the extent of progress towards completion is measured based on the ratio of costs incurred to-date to 
the total estimated costs for completion of the performance obligations. The Group generally use a cost-to-cost measure of progress because it best depicts 
the transfer of benefits to a licensee. The Group applied significant judgment in estimating the total costs for completion of performance obligations under 
such licensing and collaboration arrangements.
Research and development expenses
Elements of research and development expenses primarily include (i) payroll and other related expenses of personnel engaged in research and development 
activities, (ii) fees associated with the exclusive development rights of the Group’s in-licensed drug candidates, (iii) fees for services provided by contract 
research organizations (“CROs”), investigators and clinical trial sites that conduct the Group’s clinical studies, (iv) expenses relating to the development of 
the Group’s drug candidates, including raw materials and supplies, product testing, depreciation, and facility related expenses, and (v) other research and 
development expenses. Research and development expenses are recognized in expenses as incurred when these expenditures are used for the Group’s 
research and development activities and have no alternative future uses.
The Group applied judgment in estimating the progress of its research and development activities and completion of or likelihood of achieving milestone 
events per underlying agreements when estimating the research and development costs to be accrued at each reporting period end. The process of 
estimating its research and development expenses involves reviewing open contracts and purchase orders, communicating with personnel to identify 
services that have been performed on its behalf and estimating the level of service performed and the associated costs incurred for the services when the 
Group has not yet been invoiced or otherwise notified of the actual costs.
The Group has acquired rights to develop and commercialize product candidates. Upfront payments that relate to the acquisition of a new drug candidate, 
as well as pre-commercial milestone payments, are immediately expensed as acquired in-process research and development in the period in which they are 
incurred, provided that the new drug candidate does not also include processes or activities that would constitute a “business” as defined under U.S. GAAP, 
the drug has not achieved regulatory approval for marketing and, absent obtaining such approval, has no established alternative future use. Milestone 
payments made to third parties subsequent to regulatory approval are capitalized as intangible assets and amortized over the estimated remaining useful life 
of the related drug candidate. All development expenditures are recognized in profit or loss when incurred, as long as the conditions enabling capitalization 
of development expenses as an asset have not yet been met.

Leases 
In accordance with ASC 842, Leases (“ASC 842”) adopted on January 1, 2019, the Group determines if an arrangement is a lease at inception. Operating 
leases are included in operating lease right-of-use (“ROU”) assets, operating lease liability, and operating lease liability, non-current in the Group’s 
consolidated balance sheets. The Group does not have any finance leases since the adoption date.
ROU assets represent the Group’s right to use an underlying asset for the lease term and lease liabilities represent the Group’s obligation to make lease 
payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the commencement date based on the present value of lease 
payments over the lease term. When determining the lease term, the Group includes options to extend or terminate the lease when it is reasonably certain 
that it will exercise that option, if any. As the Group’s leases do not provide an implicit rate, the Group uses its incremental borrowing rate, which it 
calculates based on the credit quality of the Group and by comparing interest rates available in the market for similar borrowings, and adjusting this amount 
based on the impact of collateral over the term of each lease.
The Group has elected to adopt the following lease policies in conjunction with the adoption of ASU 2016-02: (i) elect for each lease not to separate non-
lease components from lease components and instead to account for each separate lease component and the non-lease components associated with that 
lease component as a single lease component; (ii) for leases that have lease terms of 12 months or less and do not include a purchase option that is 
reasonably certain to exercise, the Group elected not to apply ASC 842 recognition requirements; and (iii) the Group elected to apply the package of 
practical expedients for existing arrangements entered into prior to January 1, 2019 to not reassess (a) whether an arrangement is or contains a lease, (b) the 
lease classification applied to existing leases, and (c) initial direct costs.
Comprehensive loss
Comprehensive loss is defined as the changes in equity of the Group during a period from transactions and other events and circumstances excluding 
transactions resulting from investments by owners and distributions to owners. Among other disclosures, ASC 220, Comprehensive Income, requires that 
all items that are required to be recognized under the current accounting standards as components of comprehensive loss be reported in a financial 
statement and be displayed with the same prominence as other financial statements. For each of the periods presented, the Group’s comprehensive loss 
includes net loss, foreign currency translation adjustments and unrealized gains and losses on investment in available-for-sale debt securities, which are 
presented in the consolidated statements of comprehensive loss.
Share-based compensation
The Group grants restricted shares and stock options to eligible employees and accounts for share-based compensation in accordance with ASC 718, 
Compensation—Stock Compensation.
 
Employees’ share-based compensation awards, if equity-classified, are measured at the grant date fair value of the awards and are recognized as expenses 
over the requisite period of the award, which is generally the vesting term of share-based payment awards.
 
A change in any of the terms or conditions of share-based awards is accounted for as a modification of the awards. The Group calculates incremental 
compensation expense of a modification as the excess of the fair value of the modified awards over the fair value of the original awards immediately before 
its terms are modified at the modification date. For vested awards, the Group recognizes incremental compensation cost in the period when the 
modification occurs. For awards not being fully vested, the Group recognizes the sum of the incremental compensation expense and the remaining 
unrecognized compensation expense for the original awards over the remaining requisite service period after modification.
 
The Group generally estimates the fair value of stock option awards granted using the Black-Scholes Option Pricing Model (“BSOPM”) and a single option 
award approach. In certain cases and depending upon the nature of any given award and prevailing best practices for such awards, the Group may employ 
Monte Carlo simulation or a Binomial Option Pricing Model (”BOPM”). These models require various significant judgmental assumptions in order to 
derive a fair value determination for each type of award, including the expected term, expected volatility, time to maturity, exercise multiple, expected 
dividend yield, and risk-free interest rate. The Group gives consideration to the historical volatilities of the Group and of similar entities, when estimating 
the forward-looking volatility of its Ordinary Share Equivalent price. Expected volatility is derived from a combination of the historical volatilities of the 
Group and select publicly traded peers for a period consistent with the underlying instrument’s expected term. The expected term of options granted is 
based on historical experience and represents the period of time that options granted are expected to be outstanding. The expected 

I-MAB

F-18
Table of Contents
exercise multiple is estimated as the average ratio of the stock price to the exercise price when employees decide to voluntarily exercise their vested 
options. As the Group did not have sufficient information of past employee exercise history, it was estimated by referencing to a widely-accepted academic 
research publication. The risk-free interest rate is based on the yield curve of a zero-coupon, U.S. Treasury bond on the date the stock option award was 
granted with a maturity equal to the expected term of the stock option award. Dividend yields are based on the Group’s history and expected future actions. 
The Group has historically not paid dividends and has no foreseeable plans to pay dividends. All grants of stock options generally have an exercise price 
equal to or greater than the fair market value of the Group’s Ordinary Share Equivalent on the date of grant.
 
The Group has elected to recognize forfeitures of share-based compensation awards in the period the forfeiture occurs. Forfeitures refer to the cancellation 
or termination of stock-based compensation awards and result in the reversal of any stock compensation expense recognized from unvested awards.
Income taxes
The Group accounts for income taxes under the asset and liability method. Under the asset and liability method, deferred tax assets and liabilities are 
recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and 
their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using the enacted tax rates that 
are expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax 
assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is recorded if it is 
more likely than not that some portion or all of the deferred income tax assets will not be utilized in the foreseeable future.
The Group evaluates its uncertain tax positions using the provisions of ASC 740-10, Income Taxes, which prescribes a recognition threshold that a tax 
position is required to meet before being recognized in the financial statements. The Group recognizes in the financial statements the benefit of a tax
position which is ‘‘more likely than not’’ to be sustained under examination based solely on the technical merits of the position assuming a review by tax 
authorities having all relevant information. Tax positions that meet the recognition threshold are measured using a cumulative probability approach, at the 
largest amount of tax benefit that has a greater than fifty percent likelihood of being realized upon settlement. It is the Group’s policy to recognize interest 
and penalties related to unrecognized tax benefits, if any, as a component of income tax expense.
Segment information
Operating segments are defined as components of an entity for which separate financial information is available and that is regularly reviewed by the 
Group's chief operating decision maker (the “CODM”) in deciding how to allocate resources and assessing performance. The Group performed an 
evaluation to determine the CODM and concluded that its Chief Executive Officer was the CODM as of December 31, 2024. There was no change in the 
Group's operating or reportable segment as a result of the divestiture of its Greater China assets and business operations. 
The Group has one reportable segment that focuses on the research and development of precision immuno-oncology agents for the treatment of cancer. The 
CODM reviews the financial information presented on a consolidated basis and measures the profit or loss of the segment using consolidated net income 
(loss) from continuing operations that is also reported on the consolidated statements of comprehensive and uses cash and cash equivalents and short-term 
investments to measure segment assets. The Group does not distinguish between markets or segments for the purpose of internal reporting.
All of the Group’s long-lived assets are held in the U.S.

Loss per share
The Group presents basic and diluted loss per share and is reported separately for continuing operations and discontinued operations. Basic loss per share is 
computed by dividing net loss attributable to ordinary shareholders by the weighted average number of ordinary shares outstanding during the period. 
Diluted loss per share is calculated by dividing net loss attributable to ordinary shareholders by the weighted average number of ordinary and dilutive 
ordinary equivalent shares outstanding during the period. Ordinary equivalent shares consist of shares issuable upon the exercise of share options using the 
treasury stock method and shares issuable upon the issuance of ordinary shares for restricted shares units using the treasury stock method. Ordinary 
equivalent shares are not included in the denominator of the diluted loss per share calculation when inclusion of such shares would be anti-dilutive. The 
Group uses loss from continuing operations as the “control number” or benchmark to determine whether potential common shares are dilutive or anti-
dilutive for purposes of reporting loss per share for discontinued operations. 
Adopted accounting pronouncements
In November 2023, the FASB issued ASU 2023-07 Segment Reporting — Improving Reportable Segment Disclosures (Topic 280) (“ASU 2023-07”). The 
standard requires disclosures to include significant segment expenses that are regularly provided to the CODM, a description of other segment items by 
reportable segment, and any additional measures of a segment’s profit or loss used by the CODM when deciding how to allocate resources. The ASU also 
requires all annual disclosures currently required by Topic 280 to be included in interim periods. ASU 2023-07 is effective for the Group from January 1, 
2024, with early adoption permitted and requires retrospective application to all prior periods presented in the financial statements. The Group adopted this 
from January 1, 2024, and did not have a material impact on the Group's consolidated financial statements but required additional disclosures.
Reclassification
To facilitate comparison of information across years, $0.8 million of 2022 operating expenses were corrected by reclassifying from administrative expenses 
to research and development expenses to conform to the current year’s presentation. 
Recent accounting pronouncements 
In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740). The standard requires disaggregation of the effective rate reconciliation into 
standard categories, enhances disclosure of income taxes paid, and modifies other income tax-related disclosures. The standard is effective for the Group 
from January 1, 2025, with early adoption permitted. The ASU is currently not expected to have a material impact on the Group’s consolidated financial 
statements.

3. DISPOSAL OF TJBIO SHANGHAI
On April 2, 2024, as a part of the strategic shift to become a U.S.-based biotech, the Group completed the divestiture of its Greater China assets and 
business operations. The Group transferred 100% of the outstanding equity interest in TJBio Shanghai to TJBio Hangzhou, an unconsolidated investee 
(now collectively known as TJ Biopharma), on a cash-free and debt-free basis, for an aggregate consideration of the RMB equivalent of up to $80 million, 
contingent on TJ Biopharma's achievement of certain future regulatory and sales-based milestone events as well as royalties. The contingent consideration 
did not meet the definition of a derivative, and as such, the Group elected to account for it as a gain contingency in accordance with ASC 450—
Contingencies, and deferred the recognition of the contingent consideration until it becomes realized or realizable. Upon the completion of the divestiture 
transaction on April 2, 2024, the Group ceased to consolidate the divested entity, assets and businesses as well as its corresponding financial results, which 
includes the future development costs of the divested Greater China assets and business operations.
In accordance with ASC 205-20-45, TJBio Shanghai met the criteria as a discontinued operation as of April 2, 2024. On April 2, 2024, the assets relevant 
to the sale of TJBio Shanghai with a carrying value of $33.1 million were classified as assets held for sale, the liabilities relevant to the sale of TJBio 
Shanghai with a carrying value of $83.7 million were classified as liabilities held for sale. The Group recognized an operational loss of $6.9 million from 
the results of TJBio Shanghai and a gain of $34.4 million from the sale of TJBio Shanghai during the year ended December 31, 2024. Included in the $34.4 
million gain is the carrying value of intangible assets related to eftansomatropin alfa and TJ103 totaling $16.2 million, which were acquired from the 
business combination of I-Mab Tianjin and Tasgen Group, but the Group no longer retains the associated rights after divestiture of the Greater China assets 
and business operations. As of December 31, 2024, the gain contingency related to the contingent consideration were not resolved, therefore, no additional 
gain was recognized related to the sale of TJBio Shanghai during the year ended December 31, 2024.

7. INVESTMENTS AND PUT RIGHT LIABILITIES
(a)
Investments in TJBio Hangzhou
Series A Investments
TJBio Hangzhou, incorporated on June 16, 2019, was a wholly-owned subsidiary of I-Mab Hong Kong with registered capital of $30 million, which was 
paid up by I-Mab Hong Kong on September 14, 2020.
On September 15, 2020 (the “Series A Closing Date”), I-Mab Hong Kong entered into an equity transfer and investment agreement (the “Series A SPA”) 
with (i) a limited partnership jointly established by the management of TJBio Hangzhou to hold restricted equity of TJBio Hangzhou issued to the 
management (“Management Holdco”), (ii) a limited partnership established to hold the shares of TJBio Hangzhou for future equity incentive plan (“ESOP 
Holdco”) and (iii) a group of domestic investors in China (“Series A Domestic Investors”).
In accordance with the terms of the Series A SPA,
(i)
I-Mab Hong Kong agreed to assign all rights and obligations/ownership of certain drug candidates in different stages of development 
(“Target Pipelines”) to TJBio Hangzhou as of the Series A Closing Date as well as to transfer employment of a team of designated 
management/workforce to TJBio Hangzhou. The Target Pipelines were evaluated by an independent appraiser, with a total value of $105 
million as of the Series A Closing Date;
(ii)
Management Holdco would acquire 10% of the equity of TJBio Hangzhou from I-Mab Hong Kong with no consideration. The 10% equity 
is represented by TJBio Hangzhou’s registered capital of $3 million, and that after acquiring such equity, Management Holdco is committed 
to pay $3 million in cash to TJBio Hangzhou to fulfil its capital contribution obligations in a period of four years starting from the Series A 
Closing Date;
(iii) ESOP Holdco would acquire 5% of the equity of TJBio Hangzhou from I-Mab Hong Kong with no consideration. The 5% equity is 
represented by TJBio Hangzhou’s registered capital of $1.5 million. All of such equity would be used for TJBio Hangzhou’s future equity 
incentive plan; and
(iv) Series A Domestic Investors would acquire a total of 40% of the equity of TJBio Hangzhou from I-Mab Hong Kong with no consideration. 
The 40% equity is represented by TJBio Hangzhou’s registered capital of $12 million, and after acquiring such equity of TJBio Hangzhou, 
Series A Domestic Investors would pay $120 million collectively in cash to TJBio Hangzhou to fulfil its capital contribution obligations.
Upon closing of the Series A SPA, the registered capital of TJBio Hangzhou was $30 million. As of December 31, 2020, among the total 25,500,000 
outstanding shares of TJBio Hangzhou, 13,500,000 shares were held by I-Mab Hong Kong while the remaining 12,000,000 shares was held by Series A 
Domestic Investors. Shares subscribed by Management Holdco and ESOP Holdco, in the total number of 4,500,000, have not yet been purchased by or 
issued to Management Holdco and ESOP Holdco as of December 31, 2020.

F-24
Table of Contents
Once all 4,500,000 subscribed shares of TJBio Hangzhou are purchased by or issued to Management Holdco and ESOP Holdco, the equity interest in 
TJBio Hangzhou held by I-Mab Hong Kong, Series A Domestic Investors, Management Holdco and ESOP Holdco would be 45%, 40%, 10% and 5%
respectively. For the years ended December 31, 2023 and 2022, 750,000 and 750,000 shares were issued to Management Holdco, respectively. No shares 
were issued to Management Holdco for the year ended December 31, 2024.
On the Series A Closing Date, I-Mab Hong Kong also entered into a shareholders agreement with the aforementioned investors (the “Series A SHA”). 
According to the SHA and TJBio Hangzhou’s articles of association, the board of directors of TJBio Hangzhou shall be composed of seven directors. The 
directors shall be elected in the following ways: I-Mab Hong Kong is entitled to appoint three directors, including the chairman of the board of directors, as 
well as nominate one independent director; the Management Holdco is entitled to appoint one director; two non-related entities of the Series A Domestic
Investors are entitled to appoint one director respectively (“Investors Directors”). Each director of the board of directors shall have one vote. I-Mab Hong 
Kong, Management Holdco and ESOP Holdco agree to act in concert, as long as each of Management Holdco and ESOP Holdco respectively holds equity 
in TJBio Hangzhou, when exercising the rights as a shareholder.
As a result of the above transactions, TJBio Hangzhou became an affiliate of the Group on the Series A Closing Date in accordance with ASC 810 since 
TJBio Hangzhou met the definition of a business under ASC 805. Pipeline candidate related matters were considered to be the activities that most 
significantly impact the economic performance of TJBio Hangzhou at that stage, and these matters cannot be acted without the consent from Series A 
Investors Directors. In accordance with ASC 810-10, TJBio Hangzhou was a variable interest entity, and no shareholder shall consolidate TJBio Hangzhou 
under VIE model as neither party had the power to direct all the activities that most significantly impact the economic performance of TJBio Hangzhou. 
Therefore, the Group deconsolidated TJBio Hangzhou and retained significant influence in TJBio Hangzhou. The investment was accounted for using the 
equity method. The retained investment in the common stock of TJBio Hangzhou was initially measured at fair value in accordance with ASC 810-10-40.
Subsequently, pursuant to TJBio Hangzhou’s articles of association, the Group applied the HLBV method to allocate earnings or losses of TJBio Hangzhou 
because the liquidation rights and priorities sufficiently differ from what is reflected by the underlying percentage ownership interests. The Group 
recognized $3.6 million and $53.3 million of operating losses in equity in loss of an affiliate in the consolidated statements of comprehensive loss for the 
years ended December 31, 2023 and 2022. During the year of 2023, the Group discontinued applying the equity method since the carrying amount of the 
investment had been reduced to zero, and therefore, did not recognize any earnings or losses of TJBio Hangzhou for the year ended December 31, 2024. 
The purchase price of $3 million committed by Management Holdco under Series A SPA, representing 10% of the equity of TJBio Hangzhou, was 
significantly lower than the fair value of the corresponding subscribed shares as of the Closing Date. The excess was considered as share-based 
compensation to TJBio Hangzhou’s management for the services to be used or consumed in TJBio Hangzhou’s own operations. The share-based 
compensation was considered granted upon the Closing Date and cliff vests after five years of service from the Series A Closing Date. Consequently, the 
Group recognized its proportionate share of the compensation expense recorded by TJBio Hangzhou. For the years ended December 31, 2024, 2023 and 
2022, the Group recognized $1.1 million, $4.4 million and $4.3 million of share-based compensation expenses in equity in loss of affiliates in the 
consolidated financial statements of comprehensive loss, respectively.
Along with the equity transfer transaction, the team of designated management/workforce transferred from the Group to TJBio Hangzhou consists of 
several grantees under the Group’s 2020 Share Incentive Plan (“2020 Plan”, see Note 11 – Share-based compensation). And there were some employees 
transferred from the Group to TJBio Hangzhou in 2021 and 2022. These individuals continued to meet the definition of eligible participants under the 2020 
Plan and 2021 Share Incentive Plan (“2021 Plan”, see Note 11 – Share-based compensation) after their resignation date from the Group. Meanwhile, there 
has been no change to any of the award terms. The equity transfer transaction did not trigger the modification accounting to the share-based compensation. 
Additionally, given that TJBio Hangzhou became an affiliate to the Group upon deconsolidation, and that the other shareholders of TJBio Hangzhou are 
not providing proportionate value to sponsor the 2020 Plan and 2021 Plan nor is the Group receiving any consideration for the awards granted to 
employees of TJBio Hangzhou, the Group is required, under Topic 323, to expense the full costs of share-based compensation as incurred in the same 
period as the costs are recognized by TJBio Hangzhou. For the year ended December 31, 2024, share-based compensation income of $0.7 million and the 
years ended December 31, 2023 and 2022, share-based compensation expenses of $0.7 million and $2.1 million were recorded in the equity in loss of 
affiliates in the consolidated statements of comprehensive loss, respectively. The income for the year ended December 31, 2024 was due to forfeiture of 
shares as a result of the divestiture of the Greater China assets and business operations as discussed in Note 3 – Disposal of TJBio Shanghai.
In 2024, 2023 and 2022, TJBio Hangzhou granted stock options to its employees. Pursuant to TJBio Hangzhou’s articles of association, the Group applied 
the HLBV method to allocate earnings or losses of TJBio Hangzhou because the liquidation rights and priorities

sufficiently differ from what is reflected by the underlying percentage ownership interests. Accordingly, the Group recorded $0.6 million, $2.7 million and 
$5.0 million of share-based compensation expenses in the equity in loss of affiliates in the consolidated financial statements of comprehensive loss for the 
years ended December 31, 2024, 2023 and 2022, and in additional paid-in capital in the consolidated balance sheets as of December 31, 2024, 2023 and 
2022, respectively.
Series B Investments
In July 2022, TJBio Hangzhou entered into an equity transfer and investment agreement (the “Series B SPA”) and a shareholders agreement (the “Series B 
SHA”) with a group of domestic investors (“Series B Domestic Investors”) in China to raise approximately $46 million in RMB equivalent. Once all the 
shares of TJBio Hangzhou are purchased by or issued to its investors, including Management Holdco and ESOP Holdco, the Group would hold 40.36% 
equity interest in TJBio Hangzhou. Pursuant to the Series B SHA, Management Holdco and ESOP Holdco no longer had irrevocably consented to act in 
concert with I-Mab Hong Kong. TJBio Hangzhou remains the affiliate of the Group. The Series B financing in TJBio Hangzhou was consummated in 
2023.
The Group presented the summarized financial information of the Group’s long-term investment measured under equity method below in accordance with 
Rule 4-08 of Regulation S-X.

Series C Investment, Equity Transfer and Shares Repurchase Transactions 
On February 6, 2024, the Group entered into definitive agreements with TJBio Hangzhou and its investors to transfer the equity interests it holds in TJBio 
Hangzhou to certain participating shareholders of TJBio Hangzhou in exchange for the extinguishment of the existing repurchase obligations (see section 
(b) below) owed by I-Mab Hong Kong to those shareholders in the amount of approximately $183 million. Upon the closing of the transaction on April 2, 
2024, the total amount of potential repurchase obligations owed by the Group to the non-participating shareholders of TJBio Hangzhou was expected to 
range from $30 million to $35 million, an amount that included claims in legal arbitration proceedings by certain non-participating shareholders against I-
Mab Hong Kong in connection with the divestiture of the Greater China assets and business operations transaction. Subsequently, during the second and 
third quarters of 2024, the Group entered into share repurchase agreements with the non-participating shareholders and repurchased TJBio Hangzhou's 
equity interests held by those shareholders for a price based on the investment cost plus a contractual amount of interest. As a result, the corresponding 
redemption obligations (see section (b) below) were fully extinguished. Concurrently with the equity transfer transaction on February 6, 2024, the Group 
participated in the Series C fundraising of TJBio Hangzhou and invested $19.0 million in exchange for 5.65% of TJBio Hangzhou’s total share capital. 
Upon the completion of the repurchase transactions and the Series C investment, the Group's total ownership in TJBio Hangzhou was approximately 15% 
as of December 31, 2024. The Group does not have the ability to exercise significant influence over the operating and/or financial policies of TJBio 
Hangzhou given there is no representation on the board of directors or shared management personnel, no participation in TJBio Hangzhou's policy-making 
processes, or any significant or material intra-entity transactions.
Pursuant to the Series C shareholder agreement (“Series C SHA”), if TJBio Hangzhou fails to complete an initial public offering (“IPO”) of its shares 
before December 31, 2027, or TJBio Hangzhou voluntarily withdraws the application for the IPO or the relevant regulatory authorities rejects or 
disapproves the application for the IPO prior to June 30, 2027, the Series A, B, and C investors will have the right to require TJBio Hangzhou to repurchase 
all or part of its investor's equity interests in cash. The Group’s investment in TJBio Hangzhou’s preferred shares are therefore contingently redeemable as 
TJBio Hangzhou's redemption obligation is only satisfied upon a

future liquidity event by a specified date, which is not within the control of the investor or the issuer. As such, the Group accounted for the investment in 
TJBio Hangzhou as available-for-sale debt securities in accordance with ASC 320, Investment — Debt Securities. The investments are reported at fair value 
as of the transaction date and re-measured at each reporting period, with the changes in unrealized gains and losses included as a component of the
accumulated other comprehensive income (loss). Any impairment of the investment due to credit-related losses is reported in the consolidated statements of 
comprehensive loss. 
As of December 31, 2024, the fair value of the Group's investments in available-for-sale debt securities was $30.8 million. The Group did not have any 
investments in available-for-sale debt securities prior to 2024. During the year ended December 31, 2024, the Group recognized $12.4 million of expenses 
related to the settlement of TJ Biopharma repurchase obligations from the non-participating shareholders as the transaction price was determined based on 
the non-participating shareholders’ initial investment cost plus a contractual amount of interest compared to the fair value of the investment that was 
determined by management, using a third-party valuation specialist. The estimated equity value of TJBio Hangzhou was established using a backsolve 
method based on the recent Series C financing transaction of TJBio Hangzhou. The value was subsequently adjusted as of each reporting period by 
applying a change in the movement of a selected set of comparable companies and biotech indices. This value was then allocated towards TJBio 
Hangzhou's Series A, B and C capital structure using an option pricing method, or “OPM”, and a waterfall approach based on the order of liquidation 
preferences of the Series A, B, and C shares relative to one another. 
The Group used the following significant assumptions and inputs in the OPM to determine the fair value of the Series A, B, and C shares:

-20%

3.0 
Estimated volatility
 
95%
Risk-free rate (Based on the Chinese sovereign yield curve)
 
1.18%
In addition, various objective and subjective factors were considered to determine the fair value of the Group's Series A, B, and C shares as of each 
reporting period, including, among other factors: 
•
TJBio Hangzhou’s financial position, including cash on hand, and historical and forecasted performance and operating results;
•
the progress of TJBio Hangzhou’s research and development programs;
•
the stage of development and business strategy and the material risks related to TJBio Hangzhou’s business and industry;
•
the likelihood of achieving a liquidity event for the holders of the Series A, B, and C shares, such as an initial public offering, given 
prevailing market conditions;
•
external market conditions affecting the biotechnology industry sectors;
•
Greater China and global economic conditions; and
•
the lack of an active public market for the Series A, B, and C shares.
The assumptions underlying this valuation represented management’s best estimate, which involved inherent uncertainties and the application of 
management’s judgment. This valuation is therefore sensitive to changes in the unobservable inputs. As a result, if the Group had used different 
assumptions or estimates, or if there are changes to the unobservable inputs, the fair value of the Series A, B and C shares could have been materially 
different.
For the year ended December 31, 2024, the Group recognized $8.2 million of unrealized loss on the available-for-sale investments in accumulated other 
comprehensive income (loss) related to non-credit-related changes in the estimated fair value of TJBio Hangzhou.

shareholders of TJBio Hangzhou in accordance with provisions of the Series A SHA and Series B SHA within four years after September 15, 2020 (the 
“Repurchase Scenario”), the Series A Domestic Investors and Series B Domestic Investors (collectively, the “Domestic Investors”) had the right to elect to 
request I-Mab Hong Kong to repurchase all or any part of the equity of TJBio Hangzhou held by such Domestic Investors within three years of the 
occurrence of the Repurchase Scenario. I-Mab Hong Kong is obligated to repurchase the equity held by the Domestic Investors in cash or in I-Mab’s stock 
(subject to the approval procedures of I-Mab) within one year from the date on which any of the Domestic Investors delivers request of repurchase in 
writing. The repurchase price is determined based on the investment cost of the Domestic Investors plus a contractual amount of interest. The put right 
liabilities were recorded as non-current liabilities as of December 31, 2023 based on management’s best estimate of the timing in settlement of potential 
repurchase request from the Domestic Investors as of the balance sheet date. 
The redemption obligation written by I-Mab Hong Kong to the Domestic Investors is a freestanding equity-linked instrument, which is classified as a put 
right liability and is initially measured at fair value. Subsequent changes in fair value are recorded in other income (expenses) in the consolidated 
statements of comprehensive loss.
The Group determined the fair value of the put right with the assistance of an independent third-party valuation firm. The Group used the option pricing 
model (Finnerty model) to estimate the fair value of the put right using the following assumptions:

The model requires the input of key assumptions including the expected terms, estimated volatility, spot price and probability of triggering event for 
redemption option. The significant unobservable inputs used in the option pricing model included spot price, estimated volatility and probability of 
triggering event for redemption option. Expected terms is estimated based on the timing of a hypothetical redemption event which is assumed to be the 
earlier of expected redemption date or expected public offering date. Expected volatility is estimated based on daily stock prices of the comparable 
companies for a period with length commensurate to the expected terms of redemption event. The spot price was determined using the market approach 
with assistance from an independent third-party valuation firm. The significant unobservable inputs used in the market approach include estimated 
volatility and probability of triggering event for redemption option. The Group’s management is ultimately responsible for the determination of the spot 
price and probability of triggering event for redemption option.
Significant decreases in interval between valuation date and maturity date, estimated volatility, spot price and probability of triggering event for redemption 
option would result in a significantly lower fair value measurement.
The redemption obligations were fully extinguished as of December 31, 2024 through equity transfer and shares repurchase transactions during the year as 
described in section (a) - Investments in TJBio Hangzhou.

As of December 31, 2024, the Group had U.S. federal, state, and non-U.S. net operating losses (“NOL”) of $112.6 million, $95.6 million, and $36.6 
million, respectively. The U.S. federal NOLs may be carried forward indefinitely; the state NOLs will begin to expire in 2036, and the non-U.S. NOLs will 
begin to expire in 2026. As of December 31, 2024, the Group also has U.S. research and development tax credits of $4.3 million that will begin to expire in 
2039. 
A valuation allowance is provided to reduce the amount of deferred tax assets if it is considered as more likely than not that some portion or all of the 
deferred tax assets will not be realized in the foreseeable future. In making such determination, the Group evaluates a variety of positive and negative 
factors including the Group’s operating history, accumulated deficit, the existence of taxable temporary differences and reversal periods.
The Group has incurred net accumulated operating losses for income tax purposes since its inception. The Group believes that it is more likely than not that 
these net accumulated operating losses together with other deferred tax assets will not be utilized in the foreseeable future. Therefore, the Group has 
provided full valuation allowances for the deferred tax assets as of December 31, 2024 and 2023.
The Group evaluates each uncertain tax position (including the potential application of interest and penalties) based on the technical merits, and measure 
the unrecognized benefits associated with the tax positions. As of December 31, 2024 and 2023, the Group did not have any significant unrecognized 
uncertain tax positions.

shares in the form of ADSs in aggregate. In August 2023, the Company’s board of directors authorized the renewal of the stock repurchase program, which 
the Company refers to as the 2023 Stock Repurchase Program. Under the 2023 Stock Repurchase Program, the Company may repurchase up to $40 million 
of its ordinary shares in the form of ADSs in aggregate, for a 12-month period. The 2023 Stock Repurchase Program became effective on August 15, 2023. 
For the years ended December 31, 2024 and 2023, the Company repurchased 413,214 ordinary shares, equivalents to 179,658 ADSs, inclusive of 5 
canceled ordinary shares, in an aggregate amount of approximately $0.3 million and 10,656,794 ordinary shares, equivalents to 4,633,389 ADSs, in an 
aggregate amount of approximately $8.6 million under the authorized stock purchase program, respectively. These repurchased shares are considered not 
outstanding and therefore were accounted for under the cost method and includes such treasury stock as a component of the shareholder’s equity. The 
Company's board of directors has not, and does not intend, to renew the stock repurchase program.
For the years ended December 31, 2024 and 2023, 2,252,047 and 3,849,268 shares of treasury stock were used for the issuance of ordinary shares for

The total intrinsic value of options exercised during the years ended December 31, 2024, 2023 and 2022 was $0. 
For the years ended December 31, 2024, 2023 and 2022, the Group recognized a total employee stock ownership plan expenses of $(1.5) million, $5.1 
million and $6.8 million, respectively. The expense reduction for the year ended December 31, 2024 was largely driven by a significant reduced headcount 
due to the shift in business strategy in 2024. As of December 31, 2024, total employee stock ownership plan cost not yet recognized related to unvested 
options was $3.0 million, which is expected to be recognized over a weighted-average period of 2.6 years.
The weighted average grant-date fair value per share of stock options granted during the years ended December 31, 2024, 2023 and 2022 was $0.47, $1.26 
and $4.36, respectively.
During the year ended December 31, 2024, the Group estimated the fair value of stock options using the BSOPM on the grant date. During the years ended 
December 31, 2023 and 2022, the Group estimated the fair value of stock options using the BOPM on the grant date.
The BSOPM and BOPM require a number of assumptions in order to derive a fair value determination for each type of award. Expected volatility is 
derived from a combination of the historical volatilities of the Group and select publicly traded peers for a period consistent with the underlying 
instrument’s expected term. The expected term of options granted is based on historical experience and represents the period of time that options granted 
are expected to be outstanding. The expected exercise multiple is estimated as the average ratio of the stock price to the exercise price when employees 
decide to voluntarily exercise their vested options. As the Group did not have sufficient information of past employee exercise history, it was estimated by 
referencing to a widely-accepted academic research publication. The risk-free interest rate is based on the yield curve of a zero-coupon, U.S. Treasury bond 
on the date the stock option

Included in the awards granted during the year ended December 31, 2024, are 4,998,958 RSUs that are subject to service-based vesting conditions (the “Time-based 
Units”) and which vest over a four-year service period. The remaining 3,818,000 are performance stock unit grants (“PSU”) approved by the Company’s board of 
directors. 954,500 PSUs are performance related and will be eligible to vest upon the achievement of several progress related metrics, this award was fully vested as

conditions tied to the price of the Company's publicly traded shares at three distinct price threshold levels (the “Market-based Units”). As of December 31, 2024, the 
2,863,500 Market-based Units remained outstanding.
For the years ended December 31, 2024, 2023 and 2022, the Group recorded a total share-based compensation expense of $(1.9) million, $5.8 million and 
$8.4 million, respectively, related to the Time-based Units. The expense reduction for the year ended December 31, 2024 was largely driven by a reduced 
headcount due to the shift in business strategy in 2024. As of December 31, 2024, total share-based compensation cost not yet recognized related to 
unvested Time-based Units was $1.2 million, which is expected to be recognized over a weighted-average period of 3.0 years.
The weighted-average grant date fair value of the Time-based Units granted during the years ended December 31, 2024, 2023 and 2022 was $0.76, $10.05

For the year ended December 31, 2024, the Group recorded a total share-based compensation expense of $0.7 million related to the Performance-based 
Units. The Group did not record any share-based compensation expense related to the Performance-based Units for

the years ended December 31, 2023 and 2022. As of December 31, 2024, the Group did not have any share-based compensation cost not yet recognized 
related to unvested Performance-based Units.
The weighted-average grant date fair value of the Performance-based Units granted during the year ended December 31, 2024 was $0.76. 
Compensation expense for the Market-based Units will be recognized over the vesting period of the awards based on the fair value of the award at the grant 
date, regardless of whether the market condition is satisfied. The fair value of Market-based Units granted is estimated using a Monte Carlo simulation. For 
the year ended December 31, 2024, the Group recognized less than $0.1 million of share-based compensation expense related to the Market-based Units. 
The Group did not recognize any share-based compensation expense related to the Market-based Units for the year ended December 31, 2023 and 2022. As 
of December 31, 2024, $1.1 million of share-based compensation expense related to the Market-based Units remained to be recognized over a period of 4.2 
years.
The weighted-average grant date fair value of the Market-based Units granted was $0.40. The fair value of this award was estimated using a Monte Carlo 
simulation to address the path-dependent nature of the market-based vesting conditions. Based on the award term, equity value, expected volatility, risk-
free rate, and a series of random variables with a normal distribution, the future equity value was simulated. Each trial within the simulation includes 
assumptions of achieving a per share valuation level of the Group’s Ordinary Share Equivalents as stipulated in the agreement to determine whether the 
market-based conditions are met resulting in vesting or not, and the future value of the award.

12. LICENSING AND COLLABORATION ARRANGEMENTS
The following is a description of the Group’s significant licensing and collaboration agreements.
A. In-Licensing Arrangements
Licensing Agreement with Ferring (Olamkicept)
In November 2016, the Group entered into a license and sublicense agreement with Ferring International Center SA (“Ferring”), with respect to (i) FE301, 
an interleukin-6 inhibitor, and (ii) all pharmaceutical formulations in finished packaged form containing FE301 covered by certain patents or patent 
applications. Under this agreement, Ferring granted to the Group an exclusive, sublicensable license (excluding any non-exclusive license that Ferring 
granted to Conaris Research Institute AG under a licensing agreement entered into in November 2008) under certain Ferring intellectual property to 
research, develop, make, have made, import, use, sell and offer to sell FE301 (and the licensed products containing FE301) in mainland China, Hong Kong, 
Macau, Taiwan and South Korea. The Group also

Table of Contents
have an option to receive an exclusive, sublicensable license under certain Ferring intellectual property to research, develop, make, have made, import, use, 
sell and offer to sell FE301 (and the licensed products containing FE301) in countries in North America, the European Union and Japan that are mutually 
agreed upon by the parties.
The Group is required to use commercially reasonable efforts to obtain approval of FE301 and to promote, market, distribute and sell it in mainland China, 
Hong Kong, Macau, Taiwan, and South Korea. Such activities are to be at the Group's own cost and expense.
Under this agreement, the Group paid to Ferring an upfront license fee of $2.0 million. The Group also agreed to make milestone payments to Ferring, in 
the aggregate amount of $14.5 million, conditioned on the achievement of certain development milestones in the licensed territory, including completion of 
Phase 1b and Phase 2a clinical trials and the submission and approval of the new drug application. Further, if the Group exercises its option to receive a 
license in any of the mutually agreed upon countries in North America, the European Union and Japan, it is required to pay to Ferring an additional $3.0 
million as an upfront license fee (upon the exercise of the option), and milestone fees up to the aggregate amount of $30.0 million, conditioned upon the 
licensed product achieving certain development milestones in certain countries in the option territory.
In addition, the Group agreed to pay Ferring tiered royalties ranging from the mid-single-digit to high-single-digit percentages of annual net sales for 
countries in mainland China, Hong Kong, Macau, Taiwan, and South Korea, and from the high-single-digits to 10% of annual net sales for the mutually 
agreed upon countries in North America, the European Union and Japan. To date, the Group had not paid any royalties to Ferring.
The royalty term commences with the first commercial sale of the licensed product in the relevant country and ends upon the later of (i) 15 years from the 
date of launch, and (ii) the expiry of the last to expire patent of Ferring that includes a valid claim covering the development, making, using or selling of the 
licensed compound or licensed product in the licensed territory and/or option territory. Unless terminated earlier in accordance with the terms thereof, this 
agreement will remain in effect until the later of the expiry of the royalty term, and the first date on which the Group is not conducting any necessary and 
outstanding clinical trial with respect to the licensed product or seeking to obtain any necessary and pending regulatory approval for the licensed product, if 
applicable. This agreement may be terminated by either party for the other party’s uncured material breach, bankruptcy or insolvency. In addition, in the 
event that the original licensor terminates its license to Ferring governing any of the intellectual property sublicensed to the Group under this agreement, 
Ferring has the right to terminate this agreement with respect to such sublicenses in which case both parties will discuss in good faith how to resolve and 
mitigate to mutual satisfaction. To the extent that Ferring terminates for the Group's material breach, bankruptcy or insolvency, among other things, all 
licenses and rights granted by Ferring to the Group will automatically terminate and the licenses and rights the Group granted to Ferring will survive and 
automatically become irrevocable with the right to sublicense.
During the term of the licensing agreement, if the Group develops or acquires any improvement, modification, enhancement or addition to the licensed 
product, the Group will own and retain all rights, title and interest therein, and grant to Ferring a non-exclusive, fully paid, royalty-free, worldwide license 
thereto.
In September 2020, the Group entered into a sublicense agreement with TJBio Hangzhou, under which the Group sublicensed to TJBio Hangzhou an 
exclusive, sublicensable license to develop, manufacture and commercialize olamkicept in mainland China, Hong Kong, Macau, Taiwan and South Korea. 
In December 2021, the Group entered into a supplementary sublicensing agreement with TJBio Hangzhou, pursuant to which TJBio Hangzhou, as a sub-
licensee of olamkicept (TJ301) in Greater China and Korea, agreed to pay $3.0 million to the Group for the completion of olamkicept (TJ301) Phase 2a 
study report. After receiving the milestone payment of $3.0 million from TJBio Hangzhou, the Group made the payment of $3.0 million to Ferring during 
2022.
In May 2022, the Group entered into an amended and restated license and sublicense agreement and a cell line and manufacturing collaboration agreement 
with Ferring, under which the Group granted to Ferring an exclusive, perpetual and transferable sublicense, with the right to grant further sublicenses to 
sublicensees, under all of the intellectual properties licensed to the Group by its business partner, to research, develop, make, import, use and sell 
olamkicept as expressed by or produced by cell lines created by the Group's business partner and its affiliates in any human indications in the territories 
other than Greater China and Korea. The Group also granted to Ferring an exclusive, perpetual and royalty-free license, with right of sublicense to 
sublicensees, under the intellectual property owned or controlled by the Group which relates to cell lines created by its business partner and its affiliates, for
the research, development, making, using or selling of olamkicept, including prespecified patents and know-how and improvements thereto. In December 
2022, the Group delivered the data package defined in the first milestone of the amended and restated license and sublicense agreement with Ferring and 
recognized $5.5 million of revenue. The Group subsequently paid TJBio Hangzhou $2.75 million and reduced the amount of revenue recognized by such 
amount. To our knowledge, TJBio Hangzhou has ceased the development of olamkicept.

B. Collaboration Arrangements
Collaboration Agreement with ABL Bio
In July 2018, the Group entered into a collaboration agreement with ABL Bio, which has been subsequently amended, whereby both parties agreed to 
collaborate to develop two bispecific antibodies by using ABL Bio’s proprietary BsAb technology and commercialize them in their respective territories, 
which, collectively, include Greater China and South Korea, and other territories throughout the rest of the world if both parties agree to do so in such other 
territories during the performance of the agreement. This agreement may be terminated by either party for the other party’s uncured material breach or in 
the event that the other party challenges its patents. Also, if a party encounters insurmountable technical difficulties and risks, which cannot be resolved by 
such party within a certain period thereafter despite all reasonable efforts, such party will have the right to terminate this agreement and will no longer have 
the right to develop the licensed product. Following the divestiture of its Greater China assets and business operations and as of the date of this annual 
report, the Group's rights in the collaboration agreement are limited to a 50/50 split for worldwide rights excluding Greater China and South Korea.
Collaboration Agreements with Tracon Pharmaceuticals, Inc. 
In November 2018, the Group entered into collaboration agreements with Tracon Pharmaceuticals, Inc. (“Tracon”) whereby the Group and Tracon agreed 
to (i) co-develop the Group’s proprietary CD73 antibody, TJD5, and (ii) collaborate to co-develop up to five bispecific antibodies. Both agreements may be 
terminated by either party for the other party’s uncured material breach, bankruptcy or insolvency or for other reasons. In April 2020, Tracon issued a 
notice of disputes with respect to these agreements. In February 2021, the Group sent Tracon a notice to terminate the agreement the Group entered into 
with Tracon to co-develop TJD5, which would result in a prespecified termination fee of $9.0 million owing to Tracon. The disputes were presented to a 
binding arbitration proceeding under the Rules of Arbitration of the International Chamber of Commerce before an arbitration tribunal. On April 25, 2023, 
the arbitration award determined that the agreement in relation to TJD5 has been terminated for a pre-agreed termination fee of $9.0 million plus interest 
payable pursuant to the original agreement, and, therefore Tracon has no rights to share any future economics with the Group. In July 2023, the pre-agreed 
termination fee in relation to TJD5 and an agreed-upon portion of Tracon’s legal fees and costs to Tracon were paid by I-Mab. The financial impacts of the 
transaction were allocated to discontinued operations for the periods presented. 
Clinical Trial Collaboration and Supply Agreement with Bristol Myers Squibb
In June 2024, the Group entered into a clinical trial collaboration and supply agreement with Bristol-Myers Squibb Company (“BMS”) to evaluate the 
Group’s novel bispecific antibody, givastomig, targeting Claudin18.2 x 4-1BB in clinical trials, in combination with BMS’s anti-PD-1 monoclonal 
antibody product known as OPDIVO® (nivolumab). Under the terms of the agreement, the Group will be responsible for sponsoring and conducting, at its 
own cost, a multi-national Phase 1 trial of givastomig in combination with nivolumab. BMS will manufacture and supply a sufficient amount of nivolumab 
to the Group solely for the conduct of the combination therapy at no charge to the Group. BMS grants to the Group a non-exclusive, non-transferable, 
fully-paid-up, royalty-free license worldwide, except for certain specified territory, to use nivolumab in research and development solely to the extent 
necessary to conduct the combination therapy, seek regulatory approval for, and upon such regulatory approval, market and promote givastomig for use in 
the combination therapy with nivolumab. The Group grants to BMS a non-exclusive, non-transferable, fully-paid-up, royalty-free license worldwide, 
except for certain specified territory, to seek regulatory approval for, and upon such regulatory approval, market and promote nivolumab in the combination 
therapy with givastomig.
Global Strategic Partnership with AbbVie 
On September 3, 2020, the Group, through TJBio Shanghai and I-Mab Biopharma US Limited, entered into a license and collaboration agreement with 
AbbVie Ireland Unlimited Company (“AbbVie”), establishing a broad global strategic partnership. Prior to the divestiture of the Greater China assets and 
business operations, TJBio Shanghai was a wholly-owned subsidiary of the Group.
Pursuant to this collaboration, the Group granted AbbVie a global license, excluding Mainland China, Macau, and Hong Kong, to develop and 
commercialize lemzoparlimab (also known as TJC4), an innovative anti-CD47 monoclonal antibody internally discovered and developed by the Group for 
the treatment of multiple cancers. The Group retained all rights to develop and commercialize lemzoparlimab (as well as certain other compounds directed 
against CD47) in Mainland China, Macau, and Hong Kong. The Group was also responsible for performing the development activities at its sole expense 
as outlined in the initial development plan. Such initial development activities consisted of two studies, Study I and Study II. Study I was to be conducted 
in the United States evaluating lemzoparlimab in combination with pembrolizumab or rituximab in patients with relapsed or refractory solid tumors and 
lymphomas. 

I-MAB

Table of Contents
Study II was to be conducted in Mainland China evaluating the safety, tolerability, pharmacokinetics, pharmacodynamics and preliminary efficacy of 
lemzoparlimab in patients with acute myeloid leukemia (“AML”) or myelodysplastic syndrome (“MDS”). AbbVie had the right to conduct further global 
clinical trials (which the Group may elect to co-fund) to evaluate lemzoparlimab in multiple cancers.
Upon the satisfaction of all the pre-effect date covenants, the collaborative agreement took effect on December 10, 2020, on which date the Group was 
entitled to a non-refundable upfront payment of $180.0 million. In addition, the Group has received milestone payment of $20.0 million from AbbVie and 
is eligible to receive up to $1.74 billion in further success-based development, regulatory and sales milestone payments for lemzoparlimab, of which $840.0 
million are based on clinical development and regulatory approval milestones, with the remainder based on commercial milestones. Upon 
commercialization of lemzoparlimab, AbbVie will also pay tiered royalties from low-to-mid teen double-digit percentages on global net sales outside of 
Mainland China, Macau, and Hong Kong.
The Group identified three performance obligations: (1) grant of lemzoparlimab license upon the effective date, (2) delivering the Study I initial 
development services, and (3) delivering the Study II initial development services. 
In August 2022, the Group and AbbVie entered into an amendment to the original license and collaboration agreement dated September 3, 2020. The 
amendment modified the economics of the original agreement such that the Group will be eligible to receive, and AbbVie will pay, up to $1.295 billion in 
development, regulatory, and sales milestone payments, plus tiered royalties at rates from mid-to-high single-digit percentages on global net sales outside 
of Greater China for certain new anti-CD47 antibodies currently in development, or the original milestone payments plus tiered royalties for the already 
licensed CD47 compounds. The Group retained the exclusive right to develop and commercialize all licensed products under the agreement in Greater 
China. AbbVie discontinued its sponsored global Phase 1b combination study of lemzoparlimab plus azacitidine (“AZA”) and venetoclax in patients with 
MDS and AML, and the Phase 1b study of lemzoparlimab in patients with relapsed or refractory multiple myeloma. As a result of the amendment, the 
Group estimated the amount of consideration to which it would have been entitled to under the amended agreement and determined the probability of 
achieving the second milestone payment of $50.0 million was reduced. The Group concluded it was not probable that a significant reversal of revenue will 
not occur once the uncertainty associated with the milestone payment was resolved, thus the variable consideration of $50.0 million associated with the 
second milestone was excluded from the transaction price at the amendment date. The original consideration of $200.0 million was re-allocated to the three
performance obligations based on the relative stand-alone selling price at the amendment date. The allocated price for the grant of the lemzoparlimab 
license, Study I, and Study II was $183.0 million, $8.8 million, and $8.2 million, respectively. As of the amendment date, based on the updated transaction 
price and the progress of each performance obligation, the Group recorded in continuing operations a cumulative catch-up adjustment which resulted in a 
reduction of revenue of $5.8 million, offsetting this amount, revenue of $1.5 million was recorded for the ongoing Study I and Study II initial development 
services for the year ended December 31, 2022. 
On September 21, 2023, the Group received a notice from AbbVie, terminating the license and collaboration agreement. The termination of the license and 
collaboration agreement in its entirety by AbbVie was based on the previous program discontinuation and AbbVie’s strategic decision. The termination 
took effect on November 20, 2023. As a result, contract liabilities of $0.6 million related to Study I and Study II were recognized as revenue for the year 
ended December 31, 2023.

The Group uses loss from continuing operations as the “control number” or benchmark to determine whether potential common shares are dilutive or anti-
dilutive for purposes of reporting loss per share for discontinued operations. The control number concept requires that the same number of potentially 
dilutive securities applied in computing diluted earnings per share from continuing operations be applied to all other categories of income or loss, 
regardless of their anti-dilutive effect on such categories. The effects of all outstanding RSUs and stock options have been excluded from the computation 
of diluted loss per share for the years ended December 31, 2024, 2023 and 2022 as their effects would be anti-dilutive to the control number. The 
potentially dilutive securities that have not been included in the calculation of diluted net loss per share as their inclusion would be anti-dilutive are as

participating shareholders of TJBio Hangzhou in exchange for extinguishment of the existing repurchase obligations owed by I-Mab Hong Kong to those
shareholders.
In connection with the divestiture of its Greater China assets and business operations, the Group transferred the equity interests it held in TJBio Hangzhou 
to certain participating shareholders of TJBio Hangzhou in exchange for extinguishment of the existing repurchase obligations owed by I-Mab Hong Kong 
to those shareholders in the amount of approximately $183 million. However, the non-participating shareholders of TJBio Hangzhou have initiated legal 
proceedings against I-Mab Hong Kong and the Group in connection with the aforementioned transaction. On January 31, 2024, the non-participating 
shareholders of TJBio Hangzhou, commenced arbitration against I-Mab Hong Kong before China International Economic and Trade Arbitration 
Commission Zhejiang Sub-Commission. These non-participating shareholders sought monetary relief amounting to $17.4 million as of January 29, 2024 in 
total and an order that I-Mab Hong Kong pay all arbitration fees and property preservation fees incurred by them. The arbitration proceeding were 
concluded and I-Mab settled with the non-participating shareholders in the second half of 2024.
The Group did not have significant long-term obligations, or guarantees as of December 31, 2024 and 2023.
On March 1, 2022, the Group filed a complaint in the United States District Court for the District of Delaware, naming Inhibrx, Inc. (“Inhibrx”) and Dr. 
Brendan Eckelman as defendants (together “the Defendants”). This trial was related to the litigation against the Defendants’ alleged misappropriation of the 
Company’s preclinical and clinical trade secret data, allegedly obtained by Dr. Eckelman while acting as an expert witness for Tracon. The Company 
sought damages in the form of a lump sum reasonable royalty, along with exemplary damages for Defendants’ willful and malicious misappropriation. The 
judge bifurcated for a later bench trial the Company’s claims related to Defendants’ misappropriation of its business trade secret information. On 
November 1, 2024, a federal jury in the United States District Court for the District of Delaware found in favor of the Defendants in this bifurcated trial 
relating to a portion of the Company’s trade secret information.

This Supplementary Agreement to the Sublicense Agreement (“this Supplementary Agreement”) is entered into by and between the 
following parties on December 16, 2021 in Shanghai, the People’s Republic of China:
 
1.
I-MAB BIOPHARMA HONGKONG LIMITED, a company duly organized and existing under the laws of Hong Kong, 
China (“I-Mab Hong Kong”); and
 
2.
TJ Biopharma (Hangzhou) Co., Ltd., a limited liability company duly organized and existing in accordance with the laws of 
the People’s Republic of China (“TJBio Hangzhou”).
 
Each party is referred to individually as a “Party” and collectively as the “Parties” in this Supplementary Agreement.
 
Whereas:
 
1.
I-Mab, the Cayman Islands parent company of I-Mab Hong Kong, entered into a LICENSE AND SUBLICENSE AGREEMENT 
with Ferring International Center SA (“Ferring Pharmaceuticals”) on November 4, 2016 (including its subsequently amended 
versions, hereinafter referred to as the “Transfer and License Agreement”). According to the Transfer and License 
Agreement, I-Mab obtained the exclusive license from Ferring Pharmaceuticals for the development and commercialization 
of its FE301 product (internally designated by I-Mab as TJ301 product) in China (including Hong Kong, Macau, and Taiwan) 
and South Korea (“Licensed Territories”);
 
2.
I-Mab entered into an Assignment Agreement with I-Mab Hong Kong on July 5, 2018, pursuant to which I-Mab exclusively 
granted I-Mab Hong Kong the rights to develop and commercialize the TJ301 product in the Licensed Territories. 
Subsequently, I-Mab Hong Kong and TJBio Hangzhou entered into a Sublicense Agreement (“Original Agreement”) on 
September 15, 2020, through which I-Mab Hong Kong exclusively granted TJBio Hangzhou the aforementioned development 
and commercialization rights;
 
3.
The Original Agreement only provides general provisions regarding the licensing matters between I-Mab Hong Kong and 
TJBio Hangzhou, without specifying other detailed matters. Based on friendly consultations between the Parties, both Parties 
intend to explicitly clarify the sublicensing arrangements and payment terms therein, as well as the method of aligning with the 
economic terms in the Transfer and License Agreement.
 
Therefore, in accordance with the provisions of the Civil Code of the People's Republic of China and other relevant laws and regulations, 
and based on the principles of equality and mutual benefit, the Parties have, through friendly consultations, reached this Supplementary 
Agreement as follows:
 
Clause 1
The Parties hereby acknowledge and agree that the intent of signing the Original Agreement is solely to grant TJBio 
Hangzhou the rights to develop and commercialize the TJ301 product within the Licensed Territories by I-Mab Hong Kong. 
To avoid ambiguity, Clause 3 of the Original Agreement shall be entirely replaced with the following provision:
 
“3. The rights granted to Party B shall be consistent with the rights enjoyed by I-Mab under the Transfer and License 
Agreement in China (including Hong Kong, Macau, and Taiwan) and South Korea. Concurrently, Party B shall fulfill 
all obligations undertaken by I-Mab under the Transfer and License Agreement in China (including Hong Kong, 
Macau, and Taiwan) and South Korea.”
 
Clause 2
The Parties hereby acknowledge and agree that, notwithstanding any provision to the contrary in the Original Agreement or 
this Supplementary Agreement, as of September 15, 2020:

Exhibit 4.11
2
1)
TJBio Hangzhou shall, in accordance with Clause 3 of this Supplementary Agreement, undertake the 
obligation to pay I-Mab Hong Kong the relevant amounts that I-Mab Hong Kong is required to pay to Ferring 
Pharmaceuticals under the Transfer and License Agreement (i.e., the relevant milestone payments and royalty 
rates listed in Annex A (hereinafter collectively referred to as the “Payable Amount”; to avoid doubt, where 
there is any inconsistency between the Transfer and License Agreement and Annex A, Annex A shall prevail));
 
2)
Except for the Payable Amount under Item 1) of Clause 2 above, TJBio Hangzhou shall not be required to pay 
any other fees to I-Mab Hong Kong and/or Ferring Pharmaceuticals. However, all costs incurred by TJBio 
Hangzhou for the development and commercialization of the TJ301 product within the Licensed Territories 
shall be borne solely by TJBio Hangzhou, and I-Mab Hong Kong shall not pay any such funds in advance on 
behalf of TJBio Hangzhou.
 
Clause 3
The Parties agree that TJBio Hangzhou shall undertake the payment obligations for the Payable Amount (i.e., the milestone 
payments and royalty rates listed in Annex A) to I-Mab Hong Kong in accordance with the following provisions:
 
1)
With respect to the milestone payments listed in Annex A, TJBio Hangzhou shall pay the corresponding 
milestone amount either (A) five (5) working days prior to the Payable Amount Due Date (to avoid doubt, the 
“Payable Amount Due Date” refers to the date on which I-Mab Hong Kong is required to make the 
corresponding payment to Ferring Pharmaceuticals according to the Transfer and License Agreement); or 
(B) within fifty (50) days after the relevant milestone event listed in Annex A has been achieved, whichever 
occurs first. The corresponding milestone amount of the Payable Amount shall be paid to the account designated 
by I-Mab Hong Kong (denominated in US dollars. In case of conversion between different currencies, the 
converted amount should be sufficient to cover the actual Payable Amount from I-Mab Hong Kong to Ferring 
Pharmaceuticals at the time of payment);
 
2)
With respect to the royalty rates listed in Annex A, TJBio Hangzhou shall provide I-Mab Hong Kong with a 
report each time a royalty payment is made. The report shall include: (a) the net sales generated by the TJ301 
product in each country within the Licensed Territories; (b) the basis for any deductions applied to calculate the 
net sales from the invoiced amounts; (c) the applicable royalty rate for the TJ301 product; (d) the calculation of 
the payable royalty amount; and (e) the exchange rates applicable to the calculations mentioned above. 
 
TJBio Hangzhou shall make the payment by either (A) within fifty (50) days after the end of each calendar 
quarter starting from the first calendar quarter in which the first product sale occurs and marks the beginning of 
the first royalty period; or (B) five (5) working days prior to the Payable Amount Due Date, whichever occurs 
first. The payable royalty amount shall be paid to the account designated by I-Mab Hong Kong (denominated in 
US dollars. In case of conversion between different currencies, the converted amount should be sufficient to 
cover the actual Payable Amount from I-Mab Hong Kong to Ferring Pharmaceuticals at the time of payment). 
The provisions of the Transfer and License Agreement shall govern any matters not covered regarding the 
payment of royalties.
 
3)
To avoid doubt, TJBio Hangzhou shall have the right to fulfill the aforementioned payment obligations to I-
Mab Hong Kong through its overseas affiliate. All relevant taxes (including but not limited to withholding 
income tax) arising from payments made by TJBio Hangzhou (or its overseas affiliate) to I-Mab Hong Kong 
shall be borne by TJBio Hangzhou. Upon completion of the Payable Amount under the provisions of this 
Supplementary Agreement by TJBio 

Exhibit 4.11
3
Hangzhou (or its overseas affiliate), there shall be no requirement for TJBio Hangzhou (or its overseas affiliate) 
to make any further payments of milestone amounts or royalties to I-Mab Hong Kong according to the Transfer 
and License Agreement.
 
Clause 4
Notwithstanding the general provisions of Clause 2 under this Supplementary Agreement, the Parties hereby acknowledge 
that TJBio Hangzhou (or its overseas affiliate) shall pay a milestone payment of US$3,000,000.00 (in words: Three million US 
dollars only) or its equivalent in currency (including RMB), corresponding to the completion of the “Completion of Phase IIA 
study report in the Territory” milestone event as listed in Annex A, in one lump sum to the account designated by I-Mab Hong 
Kong (including the account of a third party designated by I-Mab Hong Kong, i.e., I-Mab Biopharma (Shanghai) Co., Ltd.) by 
December 31, 2021. The exchange rate shall be based on the mid-price of the foreign exchange rate published by the Bank of 
China on the day of payment by TJBio Hangzhou. Upon completion of the payment to the aforementioned third-party account 
by TJBio Hangzhou, the payment obligation under this clause from TJBio Hangzhou to I-Mab Hong Kong shall be deemed 
fulfilled. I-Mab Hong Kong shall issue the corresponding invoice to TJBio Hangzhou within five (5) working days after 
TJBio Hangzhou has fulfilled the payment obligation under this clause.
 
Clause 5
The Parties hereby acknowledge that if TJBio Hangzhou fails to timely and fully fulfill its obligations under this 
Supplementary Agreement, resulting in losses incurred by I-Mab Hong Kong, such liability shall be limited to those losses 
arising from TJBio Hangzhou’s failure to timely and fully fulfill its payment obligations for the Payable Amount. If such 
failure results in I-Mab Hong Kong’s failure to make timely and full payments to Ferring Pharmaceuticals, and consequently 
subjects I-Mab Hong Kong to incur liabilities and costs under the Transfer and License Agreement within the Licensed 
Territories, including but not limited to responsibilities, lawsuits, arbitrations, attorney fees, and other enforcement costs 
associated with such failures, TJBio Hangzhou shall be responsible for such losses.
 
Clause 6
The Parties acknowledge that, as of the date of signing this Supplementary Agreement, there are no actual or potential 
disputes or controversies between the Parties regarding the signing and performance of the Original Agreement.
 
Clause 7
The Original Agreement and this Supplementary Agreement shall be governed by and interpreted in accordance with the 
laws of the People’s Republic of China.
 
Clause 8
If any dispute arises between the Parties in connection with the signing or performance of the Original Agreement or this 
Supplementary Agreement, the Parties shall resolve it through friendly negotiations; if no agreement is reached through 
negotiations, either Party may submit the dispute to the Shanghai International Economic and Trade Arbitration Commission 
for arbitration in accordance with its arbitration rules effective at the time of applying for arbitration. The arbitration award shall 
be final and binding on both parties. The place of arbitration shall be Shanghai.
 
Clause 9
This Supplementary Agreement constitutes an inseparable part of the Original Agreement and shall have the same legal 
effect as the Original Agreement. In the event of any inconsistency between the provisions of this Supplementary Agreement 
and the Original Agreement, the provisions of this Supplementary Agreement shall prevail; matters not stipulated in this 
Supplementary Agreement shall continue to be governed by the relevant provisions of the Original Agreement.
 
Clause 10
This Supplemental Agreement shall come into force as of the date of signature by Parties (except that Clause 2 of this 
Supplemental Agreement shall be deemed to come into force as of September 15, 2020). This Supplementary Agreement 
shall have two (2) counterparts, with each Party holding one (1) original, both with the same legal effect.

review of such materials and abstracts, and shall return such items as soon as reasonably practicable to the publishing or 
presenting Party with appropriate comments, if any, but in no event later than sixty (60) days after the date of delivery to 
such other Party.  Failure to respond within such sixty (60) days shall be deemed approval to publish or present.

6.5	 Subcontracting. I-MAB may subcontract the Commercialization of the Licensed Product in the Field in the Territory; 
provided that any agreement pursuant to which I-MAB engages such subcontractor shall be consistent in all material 

Exhibit 4.12

[Redacted] 
7.2.2	
[Reserved]
7.2.3	
Determination that Milestone Events Have Occurred.  I-MAB shall notify Ferring promptly of the 
achievement of each Milestone Event.  In the event that, notwithstanding the fact that I-MAB has not provided Ferring 
with such a notice, Ferring believes that any such Milestone Event has been achieved and not paid, it shall so notify I-
MAB in writing and the Parties shall promptly meet and discuss in good faith whether such Milestone Event has been 
achieved.  Any dispute under this Section 7.2.3 regarding whether or not a Milestone Event has been achieved shall be 
subject to resolution in accordance with Sections 21 and 23.

7.3.1	
Royalty Rates in the Territory.  In connection with the grant of the licenses and sublicenses under the 
Licensed Know-How and Sublicensed Intellectual Property in the Territory pursuant to Section 2.1, during the Royalty

Territory in each Calendar Year (or partial Calendar Year), as follows, as calculated by multiplying the applicable 
royalty rate in the table below by the corresponding amount of incremental Net Sales of all Licensed Products:
[Redacted]
7.3.2	
[Reserved]
7.3.3	
Payment Dates and Reports.  Royalty payments shall be made by I-MAB within sixty (60) days after the end 
of each Calendar Quarter commencing with 

Exhibit 4.12
 
the Calendar Quarter in which the first day of the first Royalty Term for the first Licensed Product occurs.  I-MAB shall 
also provide to Ferring, at the same time each such payment is made, a report showing: (a) the Net Sales of the Licensed 
Product by country in the Territory; (b) the basis for any deductions from Invoiced Sales to determine Net Sales; (c) the 
applicable royalty rates for the Licensed Product; (d) a calculation of the amount of royalty due to Ferring; and (e) the 
exchange rates used in calculating any of the foregoing.
7.4	 Mode of Payment; Currency Conversion; Taxes.
7.4.1	
Mode of Payment.  All payments to Ferring under this Agreement shall be made by wire transfer of Dollars in 
the requisite amount to such bank account as Ferring may from time to time designate by notice to I-MAB.
7.4.2	
Currency Conversion.   If any currency conversion shall be required in connection with any payment 
hereunder, such conversion shall be made by using the arithmetic mean of the exchange rates for the purchase of Dollars 
as published by the People’s Bank of China, on the last Business Day of each month in the Calendar Quarter to which 
such payments relate.
7.4.3	
Taxes.  The milestone and royalty payments and other amounts payable by I-MAB to Ferring pursuant to this 
Agreement (“Payments”) shall not be reduced on account of any taxes unless required by Applicable Law.  Ferring 
alone shall be responsible for paying any and all taxes incurred under this Agreement which it should be liable for under 
the tax law of the relevant jurisdiction.  I-MAB shall deduct or withhold from the Payments any taxes that it is required 
by Applicable Law to deduct or withhold.  For the sake of clarity, any federal, state, county or municipal sales or use tax, 
excise, customs charges, duties or similar charge, or any other tax assessment (other than that assessed against income), 
license, fee or other charge lawfully assessed or charged on the manufacture, sale or transportation of Materials sold 
pursuant to this Agreement or a separate supply agreement between the Parties, shall be paid by Ferring. If Ferring is 
entitled under any applicable tax treaty to a reduction of rate of, or the elimination of, applicable withholding tax, it shall 
deliver to I-MAB or the appropriate governmental authority (with the assistance of I-MAB to the extent that this is 
reasonably required and is expressly requested in writing) the prescribed forms necessary to 

Exhibit 4.12
 
reduce the applicable rate of withholding or to relieve I-MAB of its obligation to withhold tax, and I-MAB shall apply 
the reduced rate of withholding, or dispense with withholding, as the case may be; provided that I-MAB has received 
evidence, in a form reasonably satisfactory to I-MAB, of Ferring’s delivery of all applicable forms (and, if necessary, its 
receipt of appropriate governmental authorization) at least fifteen (15) Business Days prior to the time the tax return is 
due for filing and/or that the Payments are due, whichever is earlier.  If, in accordance with the foregoing, I-MAB 
withholds any amount in connection with any Payment, it shall pay to Ferring the balance when due, make timely 
payment to the proper taxing authority of the withheld amount and send to Ferring proof of such payment within fifteen 
(15) Business Days following such Payment.
7.5	  Sub-License and Sub-Sub-License Income
	
In the event any right granted, license, sub-license or sub-sublicense given to, or agreement entered into by I-MAB with any 
Third Party (not being an Affiliate or Recognised Agent of I-MAB) in Sublicensed Intellectual Property or Licensed 
Ferring Intellectual Property or Licensed Know-How and where, but for such right granted, license, sub-license or sub-
sublicense given or agreement entered into by I-MAB, Sublicensed Intellectual Property or Licensed Ferring Intellectual 
Property or Licensed Know-How as granted by Ferring to I-MAB pursuant to this Agreement would be infringed or used 
by the commercialisation of a Licensed Product by such Third Party, I-MAB shall be deemed to have sub-licensed 
and/or sub-sublicensed its rights in the Licensed Product for the purposes of this Section 7.5 under a Third Party
Agreement (“Third Party Agreements”).
Third Party Agreements shall also include any related agreements with a Sub-licensee and/or a Sub-sub licensee such as 
for example any agreement on an exchange product for the Licensed Product or other non-financial consideration but 
shall expressly exclude sales to wholesalers under distribution agreements and sales under any other agreements which 
are covered by Section 7.3 above and where sales of Licensed Product to an end customer are not booked by I-MAB, its 
Affiliates, Sublicensees, Sub-sublicensees or Recognized Agents. For the sake of clarity, this exclusion shall not apply to 
agreements covering or related to the supply and manufacture of Licensed Compound or Licensed Product where
commercialisation of the Licensed Product accruing therefrom is covered under 

Exhibit 4.12
 
Sublicensed Intellectual Property and/or Licensed Ferring Intellectual Property and/or Licensed Know-How as granted 
by Ferring to I-MAB pursuant to this Agreement.
I-MAB shall pay to Ferring a sum equivalent to 10% (ten percent) of the annual total consideration received by I-MAB 
under all Third Party Agreements for as long as I-MAB is obliged to make payments to Ferring pursuant to section 7.3 
above. 
For the avoidance of doubt, annual total consideration received by I-MAB under Third Party Agreements shall also 
include the sales booked by I-MAB in respect of any product in-licensed and commercialized by I-MAB and acquired by 
I-MAB in consideration of any sub-license and/or sub-sublicense by I-MAB of the Licensed Product, whereupon the Net 
Sales of any such product in-licensed and commercialised by I-MAB shall be deemed annual total consideration 
received by I-MAB under a Third Party Agreement.
I-MAB will disclose to Ferring the terms of all Third Party Agreements within thirty (30) days of their conclusion in so 
far as the terms are directly applicable to the financial and/or non-financial consideration that I-MAB will receive under 
such Third Party Agreements.
Not later than thirty (30) days from the end of each calendar year, I-MAB will: (i) confirm to Ferring by itemised 
accounts the annual total consideration received in the previous calendar year by I-MAB under such Third Party 
Agreements; and (ii) make a payment to Ferring of 10% (ten percent) of such consideration as specified above.
Upon receipt by Ferring of such valuation, Ferring will have thirty (30) days either to accept in writing the accounts 
submitted by I-MAB or to inform I-MAB in writing that Ferring requires an independent accountant acceptable to both 
Ferring and I-MAB to review all Third Party Agreements and all books and accounts of I-MAB relevant for the purposes 
of determining the annual total consideration received by I-MAB during the same calendar year under such Third Party 
Agreements. Following such review, the accountant shall inform both Parties of the amount of such consideration and 
the amount shall then be binding on both Parties. Ferring may exercise the right during the term of this Agreement and 
until 

Exhibit 4.12
 
the end of three (3) years after the expiration or termination of this Agreement once per calendar year.
In the event of the independent accountant confirming an amount of annual total consideration received in the previous 
calendar year received by I-MAB under such Third Party Agreements equal to or within a margin of 5% (five percent) 
either above or below the valuation submitted by I-MAB, the costs of the independent accountant for such valuation 
shall be borne by Ferring.
In the event of the independent accountant confirming an amount of annual total consideration received by I-MAB in the 
previous calendar year under such Third Party Agreements exceeding a margin of 5% (five percent) either above or 
below the valuation submitted by I-MAB, the costs of the independent accountant for such valuation shall be borne by I-
MAB.
I-MAB shall promptly pay to Ferring the full amount of any underpayment owing to Ferring pursuant to this Section 7.5 
under such Third Party Agreements together with interest thereon at the rate of EURIBOR plus 2% (two percent) per 
year compounded monthly from the date payment was due.
7.6	 Audit Rights
I-MAB shall keep and shall cause its Affiliates, Sublicensees, Sub-sublicensees and Recognized Agents to keep records 
of the sale of the Licensed Product in sufficient detail to permit Ferring to confirm the accuracy of Net Sales and 
royalties payable reported. Ferring shall have the right at its own expense (unless the result of such audit results in a 
variation or error exceeding 5% (five percent) of the payment made in the previous calendar year, in which case at the 
expense of I-MAB), to have a certified public accounting firm examine the relevant books and records of I-MAB, its 
Affiliates, Sublicensees, Sub-sublicensees and Recognized Agents. Ferring may exercise this right during the term of 
this Agreement and until the end of three (3) years after the end of the Royalty Term once per calendar year. I-MAB 
shall promptly pay to Ferring the full amount of any underpayment, together with interest thereon, at the rate of 
EURIBOR plus 2% (two percent) per year compounded monthly from the date payment was due.
7.7	 Confidentiality.  Both Parties shall treat all information subject to review under this Section 7 in accordance with the 
confidentiality provisions of Section 5.

Exhibit 4.12
 
 
8.	
INTELLECTUAL PROPERTY
8.1	 Ownership of Intellectual Property.
8.1.1	
Except as expressly set out herein, this Agreement does not affect the ownership of any I-MAB IP, Ferring 
Intellectual Property, Licensed Know-How, Ferring Improvements or the Sublicensed Intellectual Property.  The Parties 
acknowledge and agree that, as between the Parties: (a) subject to the terms and conditions of this Agreement, including 
Section 10.3, I-MAB shall own and retain all right, title and interest in and to any and all I-MAB IP including I-MAB 
Improvements; and (b) Ferring shall own and retain all right, title and interest in and to any and all Licensed Know-How, 
Ferring Intellectual Property and Ferring Improvements; (c) Conaris Research Institute AG shall own and retain all right, 
title and interest in and to any and all Sublicensed Intellectual Property and (d) each Party shall own and retain all right, 
title and interest in and to any and all other Know-How and other intellectual property rights that are owned or otherwise 
Controlled (other than pursuant to the license grants set forth in Section 2.1 and 2.2) by such Party, its Affiliates or any 
Sublicensees, Sub-sublicensees or its or their respective Affiliates.   
8.1.2	
If an Improvement is made by or on behalf of both I-MAB and Ferring, then such Improvement shall be 
deemed jointly-owned Intellectual Property and such Intellectual Property shall be licensed by Ferring to I-MAB under 
the terms of this Agreement. 
8.1.3	
I-MAB hereby grants to Ferring a non-exclusive, fully paid, royalty free, world-wide license to any I-MAB IP. 
8.1.4	
No other right of license.  Except as expressly set out herein, no provision in this Agreement shall operate to 
transfer, assign or otherwise grant any Party any right or interest in any Intellectual Property or other intellectual 
property rights of the other Party.
8.2	 Patent Filing, Prosecution and Maintenance
8.2.1	
Licensed Patents.   Ferring shall prepare, file, prosecute and maintain (including with respect to related 
interference, re-issuance, re-examination, 

Exhibit 4.12
 
opposition and invalidation proceedings) the patents and patent applications of the Ferring Intellectual Property and 
Sublicensed Intellectual Property in the Territory at its sole cost and expense, and shall not abandon any such patent or 
patent application in the Territory without the prior written consent of I-MAB which shall not be unreasonably withheld.
8.2.2	
Improvements. The Party owning an Improvement shall have responsibility for the filing, prosecution and 
maintenance of patents and patent applications covering such Improvement at its sole expense, in the applicable patent 
offices in the Territory, and that Party shall control all filings and actions in relation to procuring and maintaining such 
patents and patent applications. Ferring shall have responsibility for the filing, prosecution and maintenance of patents 
and patent applications covering jointly owned Improvements, provided that Ferring shall provide I-Mab drafts of any 
material filings or responses to be made to patent authorities in the Territory with respect to such patents and patent 
applications covering the jointly owned Improvements sufficiently in advance of submitting such filings or responses so 
as to allow for a reasonable opportunity for I-Mab to review and comment thereon, and Ferring shall reasonably consider 
any requests and suggestions timely provided by I-Mab with respect to such drafts.  The Parties agree to keep each other 
regularly informed of the course of patent prosecution or other proceedings with respect to Improvements and shall 
provide each other with copies of all official documents sent to or received by the respective patent offices in the 
Territory.
Notwithstanding the foregoing, the Party having such responsibility for the filing, prosecution and maintenance of 
Improvements shall not be required to file, prosecute or maintain any patent application or patent where that Party does 
not believe that such activities are commercially justified provided, however, that such Party shall not cease to file, 
prosecute and maintain any such patent application or patent without giving the other Party the opportunity to take over 
the responsibility for filing, prosecution and maintenance at its own expense in which case that Party shall grant the 
other Party an irrevocable, non-exclusive, fully paid, royalty free, world-wide license, with the right to sublicense to 
such Improvements. The Parties agree and acknowledge that Conaris has the 

Exhibit 4.12
 
opportunity to take over responsibility for any Improvements should both Parties decline to maintain patents or patent 
applications on Improvements.
8.3	 Cooperation and Assistance
Each Party shall make available its authorized attorneys, agents or representatives, its employees, agents or consultants
reasonably necessary or appropriate to enable the other Party to file, prosecute and maintain patent applications and 
resulting patents with respect to the Improvements, and shall provide access to such documents and other information as 
may be reasonably required for such purposes. The Party shall sign or cause to have signed all documents relating to said 
patent applications or patents at no cost or charge to the other Party. 
8.4	 Patent Term Extensions and Supplementary Protection Certificates.
Each Party shall notify the other Party of the issuance of each patent within the Ferring Intellectual Property or I-MAB 
IP in any country in the Territory giving the date of issue and patent number for each such patent. Ferring shall have the 
exclusive responsibility and shall use commercially reasonable efforts to apply for and maintain any such extension,  and 
shall not abandon any such extension in the Territory without the prior written consent of I-MAB which shall not be 
unreasonably withheld.
The Parties shall cooperate with each other in gaining such extensions and each Party shall execute such authorizations 
and other documents and take such other actions as may be reasonably requested by the other Party to obtain such 
extensions. If more than one patent is eligible for such extension, Ferring shall have the right to make the election of 
which patent for which such extension will be sought. 
8.5	 Patent Enforcement and Infringement
8.5.1	
Notice.	  If Ferring or I-MAB has knowledge of any suspected infringement of any Intellectual Property by 
Third Parties or of any misappropriation or misuse of the Intellectual Property in the Territory, the Party having such 
knowledge shall promptly inform the other Party of such infringement, misuse or misappropriation.
8.5.2	
Course of Action. I-MAB shall have the right, but not the obligation, at its cost to bring any legal action in the 
Territory related to infringement by Third 

Exhibit 4.12
 
Parties, that impacts adversely on the enjoyment by I-MAB of the rights licensed to it hereunder. Ferring shall join in 
any infringement proceeding as a party at I-MAB’s request and at I-MAB’s expense in the event that an adverse party 
asserts, or I-MAB determines in good faith, that a court or other legal body lacks jurisdiction based on Ferring’s absence 
as a party in such proceeding, or with respect to patents where such joinder is necessary or desirable to proceed with 
such claim.  Ferring and Conaris shall each have the right, but not the obligation, to bring any legal action related to 
infringement if I-MAB declines to do so. 
8.5.3	
Infringement of Third Party Rights. In the event that a Third Party alleges that I-MAB’s or its Affiliate’s, 
Sublicensee’s and/or Sub-sublicensee’s, manufacture of the Licensed Product or use of Improvements infringes its 
intellectual property in the Territory, I-MAB shall have the sole right to defend such action at its own expense and 
Ferring agrees to assist and cooperate where reasonably necessary with I-MAB, at I-MAB’s own expense, in the defense 
of any such action.
I-MAB has carried out its own analysis of Third Party patent rights in the Territory which could possibly be infringed or 
be alleged to be infringed by its exercise of the rights under this Agreement. I-MAB acknowledges that the grant of the 
license and/or sublicense under this Agreement shall not imply any warranty against infringement of any Third Parties’ 
patent rights or any other rights of Third Parties. Ferring and I-MAB are in agreement that Ferring shall not be liable for 
any patent infringement claims brought by a Third Party against I-MAB with regard to the manufacture or marketing of 
the Licensed Product in the Territory and shall be under no duty to indemnify I-MAB from claims and damages arising 
therefrom.
8.5.4	
Settlement of Third Party Claims. I-MAB, with respect to a particular claim pursuant to Section 8.5.3, also 
shall have the right to control settlement of such claim; provided that: (a) no settlement shall be entered into without the 
prior consent of Ferring if such settlement would adversely affect or diminish the rights and benefits of Ferring under 
this Agreement, or impose any new obligations or adversely affect any obligations of Ferring under this Agreement; and 
(b) I-MAB  shall not be entitled to settle any such claim by granting a license or covenant not to sue under or with 
respect to the Sublicensed Intellectual Property or Ferring 

Exhibit 4.12
 
Intellectual Property without the prior written consent of Ferring, such consent not to be unreasonably conditioned, 
withheld or delayed.
8.5.5	
Costs. Each Party shall unless otherwise stated in this Section 8.5 assume and pay all of its own out-of-pocket 
costs incurred in connection with any litigation or proceedings described in this Section 8.5, including, without 
limitation, the fees and expenses of such Party’s counsel.
8.5.6	
Recoveries. Any recovery obtained by either Party as a result of any proceeding described in this Section 8.5 
or from any counterclaim or similar claim asserted in a proceeding described in this Section 8.5, by settlement or 
otherwise, shall be applied as follows: first, to reimburse each Party for all out-of-pocket litigation costs incurred in 
connection with such proceeding paid by that Party (on a pro rata basis based on each Party’s respective litigation costs, 
to the extent the recovery was less than all such litigation costs); and second, the remainder of the recovery shall be paid 
one hundred  percent (100%) to the Party which funded the infringement action.  Any remainder of the recovery by I-
MAB shall be treated as sub-license income pursuant to Section 7.5.
8.5.7	
Cooperation.  In the event that any Party takes action pursuant to this Section 8.5, the other Party shall 
cooperate fully with the Party so acting to the extent reasonably possible, including the joining of suit as required by this 
Agreement or as otherwise desirable and, to the extent possible, make available relevant records, papers, information, 
samples, specimens, and the like. Each Party shall keep the other informed of developments in any action or proceeding, 
including the status of any settlement negotiations and the terms of any offer related thereto. 
 8.6	 Validity and Enforceability Challenge by Third Party
In the event that a Third Party attacks the validity or enforceability of any of the Ferring Intellectual Property in the 
Territory, then Ferring shall promptly notify I-MAB and Ferring, at its own discretion, subject to good business 
judgement, shall promptly take such legal action as is required and appropriate to defend the validity thereof. 
If Ferring does not take such legal action as is required to defend the validity of the Ferring Intellectual Property in the 
Territory, Ferring shall provide at least 

Exhibit 4.12
 
sixty (60) days written notice to I-MAB prior to a corresponding deadline, if applicable, and the Parties shall reasonably 
determine an appropriate alternative in the best interests of both Parties. 
The Parties agree and acknowledge that should a Third Party attack the validity or enforceability of any of the 
Sublicensed Intellectual Property in the Territory and Ferring does not take such legal action as is required to defend the 
validity of such Sublicensed Intellectual Property, then Conaris at its option shall control defense.
8.7	 Product Trademarks
8.7.1	
Maintenance and Ownership of Product Trademarks.  I-MAB, at its expense, shall be responsible for the 
selection, registration and maintenance of all Trademarks that I-MAB employs in connection with the Licensed Product 
(“Product Trademarks”). I-MAB shall own all right, title and interest to such Trademarks, trade dress and copyrights 
in the Territory related to the Licensed Product.
8.7.2	
Enforcement of Product Trademarks.  I-MAB may, at its sole discretion, take such action as I-MAB deems 
necessary against a Third Party based on any alleged, threatened, or actual infringement, dilution, misappropriation, or 
other violation of, or unfair trade practices or any other like offense relating to, the Product Trademarks by a Third Party 
in the Territory.  I-MAB shall bear the costs and expenses relating to any enforcement action commenced pursuant to 
this Section 8.7.2 and any settlements and judgments with respect thereto, and shall retain any damages or other amounts 
collected in connection therewith.
8.7.3	
Third Party Claims.  I-MAB may, at its sole discretion, defend against any alleged, threatened, or actual 
claim by a Third Party that the use or registration of the Product Trademarks in the Territory infringes, dilutes, or 
otherwise violates any trademark or other right of such Third Party or constitutes unfair trade practices or any other like 
offense, or any other claims as may be brought by a Third Party against a Party in connection with the use of the Product 
Trademarks with respect to a Licensed Product in the Territory.  I-MAB shall bear the costs and expenses relating to any 
defense commenced pursuant to this Section 8.7.3 

Exhibit 4.12
 
and any settlements and judgments with respect thereto, and shall retain any damages or other amounts collected in 
connection therewith.
8.7.4	
Notice and Cooperation.  Each Party shall provide to the other Party prompt written notice of any actual or 
threatened infringement of the Product Trademarks in the Territory and of any actual or threatened claim that the use of 
the Product Trademarks in the Territory violates the rights of any Third Party.  Each Party shall cooperate fully with the 
other Party with respect to any enforcement action or defense commenced pursuant to this Section 8.7.
 
9.	
TERM AND TERMINATION
9.1	 Term.  This Agreement shall commence on the Initial Effective Date and shall, unless earlier terminated in accordance with 
this Section 9, continue: (a) with respect to the Licensed Product in each country in the Territory, until the expiration of 
the Royalty Term for the Licensed Product in such country; and (b) with respect to this Agreement in its entirety, until 
the later of: (i) the expiration of the Royalty Term for the Licensed Product for which there has been a First Commercial 
Sale in the Territory; or (ii) the first date on which I-MAB is not conducting any necessary and outstanding Clinical 
Study with respect to any Licensed Product or seeking to obtain any necessary and pending Regulatory Approval for the 
Licensed Product in the Territory (such period, the “Term”).
9.2	 Termination of this Agreement for Material Breach.  In the event that either Party materially breaches this Agreement 
(such Party, the “Breaching Party”), in addition to any other right and remedy the other Party (the “Complaining 
Party”) may have, the Complaining Party may terminate this Agreement, in its entirety upon thirty (30) days’ prior 
written notice (the “Termination Notice Period”) to the Breaching Party, specifying the material breach and its claim of 
right to terminate, provided that the termination shall not become effective at the end of the Termination Notice Period if 
the Breaching Party cures the material breach complained of during the Termination Notice Period.
9.3	 Termination Upon Insolvency.  Either Party may terminate this Agreement if, at any time, the other Party: (a) files in any 
court or agency pursuant to any statute or regulation of any state, country or jurisdiction, a petition in bankruptcy or 

Exhibit 4.12
 
insolvency or for reorganization (other than for the purposes of merger or amalgamation) or for an arrangement or for 
the appointment of a receiver or trustee of such other Party or of its assets; (b) proposes a written agreement of 
composition or extension of its debts; (c) is served with an involuntary petition against it, filed in any insolvency

9.4	 Termination of Sublicensed Intellectual Property.  Ferring may terminate this Agreement with respect to the license grant 
hereunder to Sublicensed Intellectual Property in the event the Development and License Agreement dated November 
11, 2008 governing the Sublicensed Intellectual Property (the “Main License”) is terminated by Conaris AG. The 
Parties hereby agree to discuss in good faith how to resolve and mitigate to the satisfaction of both Parties any

(5) The Parties agree that Sections 11.2.1 through 11.2.51 of the Prior Agreement (as added by that certain 
Amendment Six to Collaboration Agreement executed by and between ABL Bio and TJBio SH on September 24, 2021) shall be incorporated 
herein by reference and that TJBio SH shall have the same rights and shall perform the same obligations under Sections 11.2.1 through 11.2.5 
of the Amended Collaboration Agreement as if TJBio SH were a “Party”, and TJBio SH and I-Mab US were jointly “I-MAB Biopharma”,
each as referred to in such sections.
(6) I-Mab US and TJBio SH further agree that, subject to Sections 2.6(1) through 2.6(5) above, as between I-

in this Section 2.6(6) shall constitute the I-Mab US IP (as defined below) and the TJBio SH IP, as applicable.  Each Party will coordinate 
with the other Parties with respect to the preparation, filing, prosecution, maintenance and enforcement of (x) any patents that arise from this 
Section 2.6(6), in the case of I-Mab US or TJBio SH, as applicable, and (y) any patents that arise from or are used by ABL Bio in its
exploitation of CLDN18.2/4-1BB BsAb, in the case of ABL Bio, which coordination in each case of (x) and (y) shall include each Party 
providing reasonable assistance to allow another Party (the “Step-In Party”) to take over the filing, prosecution, maintenance and 
enforcement of such patents that such first Party intends to abandon, solely in jurisdictions where the Step-In Party is entitled to exploit 
CLDN18.2/4-1BB BsAb under the Amended Collaboration Agreement and at the Step-In Party’s sole expense.  For clarity, this Section 
2.6(6) shall not affect ABL Bio’s ownership, right and interest in Patent Rights and Know-How already owned by ABL Bio pursuant to the 
Prior Agreement. 
3. Licenses.

that becomes such Affiliate after the Effective Date as the result of a merger, acquisition or other change of control transaction of I-Mab US 
or any Affiliate of I-Mab US.  For clarity, “I-Mab US IP” shall include clinical data obtained from I-Mab US collaborators in the 
development of CLDN18.2/4-1BB BsAb.  I-Mab US collaborators that have generated such clinical data with I-Mab US shall have the right 
to pursue label expansions for their products in Greater China.
(4) TJBio SH shall be obligated to act in a manner consistent with all the terms in the Amended Collaboration 
Agreement applicable to a sublicensee.  To the extent any act and omission of TJBio SH causes I-Mab US to be in breach of the Amended

Article 8.
Confidentiality
 8.1.Nondisclosure of Confidential Information.
(a)
Prior to the Effective Date, the Company and BMS entered into a certain Mutual Confidentiality Agreement 
dated February 23, 2023, as amended (the “CDA”).  Any information previously disclosed by the Parties pursuant to the CDA that is 
related to or otherwise used in connection with the Combined Therapy Study shall now be Confidential Information for purposes of this 
Agreement and the Parties shall treat it as such in accordance with the terms hereof, and such information shall be subject to the terms 
and conditions of this Agreement and shall no longer be subject to the CDA.  All written, visual, oral and electronic data, information, 
know-how or other proprietary information or materials, both technical and non-technical, disclosed by one Party to any other Party 
pursuant to this Agreement that if in tangible form, is labeled as “proprietary” or “confidential” (or similar reference) in oral or visual 
form within [Redacted] calendar days thereafter shall be “Confidential Information” of the disclosing Party, and all Study Data and 
Inventions shall be the Confidential Information of the Party owning such Study Data or Invention (as provided in Section 7.2 with regard 
to Study Data and Section 5.1 with regard to Inventions).  For purposes of this Agreement, regardless of which Party discloses such 
Confidential Information to the other, all Company Study Inventions, Company Technology, and Company Regulatory Documentation 
shall be Confidential Information of the Company and BMS shall be the receiving Party, and all BMS Study Inventions, BMS Technology, 
and BMS Regulatory Documentation shall be Confidential Information of BMS and the Company shall be the receiving Party.
(b)
Except to the extent expressly authorized in this Section 8.1 and Sections 7.4,  7.5,  8.2, 8.3 and 8.4, or as 
otherwise agreed in writing by the Parties, each Party agrees that, for the Term and for a period 

 
	
	
Page 30
of [Redacted] years thereafter, it shall keep confidential and shall not publish or otherwise disclose and shall not use for any purpose 
other than as expressly provided for in this Agreement any Confidential Information owned solely by the other Party, treat the other 
Party’s Confidential Information with the same degree of care the receiving Party uses for its own confidential information but in no 
event with less than a reasonable degree of care, and reproduce the disclosing Party’s Confidential Information solely to the extent 
necessary to perform the receiving Party’s obligations (or to exercise its rights) under this Agreement, with all such reproductions being 
considered the disclosing Party’s Confidential Information.  Notwithstanding anything to the contrary in this Section 8.1, and subject to 
Sections 7.4, and 7.5, the receiving Party may disclose the disclosing Party’s Confidential Information to its employees, consultants, 
agents or permitted sublicensees for the purpose of fulfilling the receiving Party’s obligations (or exercising its rights) under this 
Agreement; provided that any such employees, consultants, agents or permitted sublicensees are bound by obligations of confidentiality 
similar to those set forth in this Agreement, and the receiving Party remains liable for the compliance of such employees, consultants, 
agents or permitted sublicensees with such obligations.
 8.2.Exceptions.  The obligations in Section 8.1 shall not apply with respect to any portion of Confidential Information that the 
receiving Party can demonstrate by contemporaneous tangible records or other competent proof:
(a)
was already known to the receiving Party (or its Affiliates), other than under an obligation of confidentiality, 
either (i) at the time of disclosure by the disclosing Party, or (ii) if applicable, at the time that it was generated hereunder, whichever ((i) 
or (ii)) is earlier;
(b)
was generally available to the public or otherwise part of the public domain either (i) at the time of its 
disclosure to the receiving Party, or (ii) if applicable, at the time that it was generated hereunder, whichever ((i) or (ii)) is earlier;
(c)
became generally available to the public or otherwise part of the public domain after its disclosure or 
generation and other than through any act or omission of the receiving Party in breach of this Agreement;
(d)
was disclosed to the receiving Party (or its Affiliates), other than under an obligation of confidentiality, by a 
Third Party who had no obligation to the Party owning or Controlling the information not to disclose such information to others; or
(e)
was independently discovered or developed by the receiving Party (or its Affiliates) without the use of or 
reference to the Confidential Information belonging to the disclosing Party as evidenced by written records.
 8.3.Authorized Disclosure.  Notwithstanding any other provision of this Agreement, each Party may disclose Confidential 
Information belonging to the other Party to the extent such disclosure is necessary in the following instances:
(a)
filing or prosecuting Patent Rights with respect to any Inventions;
(b)
prosecuting or defending litigation brought in connection with any Third Party Claim or under the terms of this 
Agreement;
(c)
complying with Applicable Law or the rules or regulations of any securities exchange on which such Party’s 
stock is listed;

 
	
	
Page 31
(d)
disclosure, in connection with the performance of this Agreement by a Party, to such Party’s Affiliates, 
permitted sublicensees, contractors, ethics committees and IRBs, CROs, academic institutions, consultants, agents, investigators, and 
employees and contractors engaged by Study Sites and investigators involved with the Combined Therapy Study and who have a need 
to know such information in connection with the proper performance the Combined Therapy Study, each of whom prior to disclosure 
must be bound in writing by similar terms of confidentiality and non-use at least equivalent in scope to those set forth in this Article 8, 
where such period of confidentiality shall last for time period stated in Section 8.1;
(e)
disclosure of the Combined Therapy Study Data, Combined Therapy Inventions and Combined Therapy Patents 
to Regulatory Authorities in connection with the development of the Combined Therapy, the Company Compound (in the case of the 
Company) or the BMS Compound (in the case of BMS);
(f)
disclosure of Combined Therapy Study Data in accordance with Sections 7.4 or 7.5 (as applicable); and
(g)
disclosure of relevant Safety Information contained within the Combined Therapy Study Data to investigators, 
institutional review boards and/or ethics committees and Regulatory Authorities that are involved in other clinical trials of the Company 
Compound with respect to the Company, and the BMS Compound with respect to BMS, and (in the event of a Material Safety Issue) to 
Third Parties that are collaborating with the Company or BMS, respectively in the conduct of such other clinical trials of the Company 
Compound or the BMS Compound, in each case solely to the extent necessary for the proper conduct of such clinical trials and/or to 
comply with Applicable Law and regulatory requirements.
Notwithstanding the foregoing, if a Party is required or otherwise intends to make a disclosure of the other Party’s 
Confidential Information pursuant to Section  8.3(b), or Section 8.3(c), it shall give advance notice to such other Party of such impending 
disclosure and endeavor in good faith to secure confidential treatment of such Confidential Information and/or reasonably assist the 
Party that owns such Confidential Information in seeking a protective order or other confidential treatment.  If a Party intends to make a 
disclosure of the other Party’s Confidential Information pursuant to Section 8.3(a) it shall give advance notice to such other Party of such 
intended disclosure, and the Parties shall cooperate with respect to the timing and secure the other Party’s permission to make such 
disclosure taking into account the non-disclosing Party’s plans for Patent filings on Inventions in accordance with Section 5.1.
 8.4.[Redacted]
 8.5.Press Releases and Publications.
(a)
Neither Party may issue any external communication, including, without limitation, an initial press release to be 
issued by the Company, subsequent press releases, Q&As, and the content and wording of any listing of the Combined Therapy Study 
required to be listed on a public database or other public registry such as www.clinicaltrials.gov, unless agreed to in writing by the other 
Party, provided, however, that each Party shall have the right to issue such external communications, including with respect to listing on 
www.clinicaltrials.gov, to the extent such external communication is required to comply with Applicable Law.  If the Parties agree to 
issue an external communication, the Parties shall also agree to the content and timing of such external communication. 
Notwithstanding the foregoing, information contained in external communications previously approved by the Parties may be included 
in subsequent external communications (but not subsequent press releases, which shall be subject to review and approval by the 
Parties in accordance with this Section  8.5(a)) by either Party without review by, or the necessity to obtain prior approval from, the 
other Party.  For clarity, if either Party terminates this Agreement pursuant to Section 11.3, the Parties shall mutually agree upon any 

 
	
	
Page 32
external communication related to such termination, which shall not include the rationale for such termination unless (and to the 
extent) mutually agreed by the Parties; provided that either Party shall be permitted to publicly disclose information that such Party 
determines in good faith is necessary to be disclosed to comply with Applicable Law or the rules or regulations of any securities 
exchange on which such Party’s stock may be listed, or pursuant to an order of a court or governmental entity.
(b)
The Company and BMS agree to collaborate to publicly disclose, publish or present (i) top-line results from the 
Combined Therapy Study, limited if possible to avoid jeopardizing the future publication of the Study Data at a scientific conference or in 
a scientific journal, solely for the purpose of disclosing, as soon as reasonably practicable, the safety or efficacy results and conclusions 
that are material to either Party under applicable securities laws, and (ii) the conclusions and outcomes (the “Results”) of the Combined 
Therapy Study at a scientific conference as soon as reasonably practicable after the completion of the Combined Therapy Study, subject 
in the case of (ii) to the following terms and conditions.  The Company shall take the lead in drafting the first joint abstract, presentation 
or publication of the interim (as appropriate) and final Results of any of the Combined Therapy Study.  Thereafter, both Parties shall 
have the right to propose disclosure, publication or presentation of the previously disclosed Results.  The Party proposing to disclose, 
publish or present the Results shall deliver to the other Party a copy of the proposed disclosure or publication at least [Redacted] 
calendar days before submission to a Third Party, or, in the case of any abstract, poster or presentation, at least [Redacted] calendar 
days before submission to a Third Party.  The reviewing Party shall determine whether any of its Confidential Information that may be 
contained in such disclosure, publication, abstract, poster or presentation should be modified or deleted, whether to file a patent 
application on any Company Study Invention (solely with respect to the Company) or BMS Study Invention (solely with respect to BMS) 
or Combined Therapy Invention disclosed therein.  Scientific publications must also undergo appropriate review for medical accuracy 
and be submitted for disclosure approval prior to submission and presentation.  Medical accuracy reviews must ensure all scientific 
publications involving BMS or the Company are supported by data or evidence and represent scientifically objective and accurate 
presentation and interpretation of data.  All reviewer comments must be clearly delineated for authors’ consideration.  Any differences 
in interpretation of findings by a Party and authors are to be resolved by scientific debate with the authors maintaining control of the 
publication content. The disclosure, publication or presentation shall be delayed for up to an additional [Redacted] calendar days (i.e., a 
total of up to [Redacted] calendar days from the initial proposal) if the reviewing Party reasonably requests such extension to allow time 
for the preparation and filing of relevant patent applications.  If the reviewing Party reasonably requests modifications to the disclosure, 
publication, abstract, poster or presentation to prevent the disclosure of a material trade secret or proprietary business information or 
for reasons of medical accuracy, the publishing Party shall edit such publication to prevent the disclosure of such information prior to 
submission of the disclosure, publication, abstract, poster or presentation.  In the event of a disagreement as to content, timing and/or 
venue or forum for any disclosure, publication or presentation of the Results, such dispute (a “Publication Dispute”) shall be referred to 
the JPT; provided that, in the absence of agreement after such good faith discussions, and upon expiration of the [Redacted] calendar 
day period (or as applicable up to [Redacted] calendar day period) as outlined above, academic collaborators engaged by the Company 
in connection with the performance of the Combined Therapy Study may publish Combined Therapy Study Data obtained by such 
academic collaborator solely to the extent that such ability to publish such Combined Therapy Study Data is set forth in an agreement 
between the Company and such academic collaborator relating to the conduct of the Combined Therapy Study.  Authorship of any 
publication shall be determined based on the accepted standards used in peer-reviewed academic journals at the time of the proposed 
disclosure, publication or presentation. The Parties agree that they shall make reasonable efforts to prevent publication of a press 
release that could jeopardize the future publication of Study Data at a scientific conference or in a scientific journal but in no way will 
this supersede the requirements of any Applicable Law or the rules or regulations of any securities exchange or listing entity on which a 
Party’s stock is listed.

 8.6.Compliance with Sunshine Laws.  For purposes of compliance with reporting obligations under Sunshine Laws, as between 
the Parties, the Company will report all payments or other transfers of value (“POTV”) made by or on behalf of the Company related to 
the conduct of the Combined Therapy Study and any applicable associated contractor engagements.  Interpretation of the Sunshine 
Laws for purposes of reporting any POTV shall be in the Company’s sole discretion.  Each Party will also provide the other Party with any 
information reasonably requested by such Party to comply with its reporting obligations under Sunshine Laws.  For purposes of this 
Section 8.6, “Sunshine Laws” means Applicable Laws requiring disclosure of POTVs to certain healthcare providers, entities and 
individuals, including Section 6002 of the Patient Protection and Affordable Health Care Act of 2010 and implementing regulations 
thereunder.
 8.7.Patient Privacy and Data Protection
(a)
Each Party shall comply with Applicable Laws relating to patient privacy and data protection.  Such compliance 
includes obtaining, when applicable and in a manner consistent with Applicable Law, consent from each Study subject to provide such 
subject’s personally identifiable information to the Study doctor for purposes of the study. Such information will be de-identified in 
accordance with the Health Insurance Portability and Accountability Act (HIPAA) and local data protection laws and will be used by the 
Company and its representatives, collaborators (including, as applicable, BMS and its Affiliates) and licensees for the purposes of (i) 
conducting the Combined Therapy Study, and performing the Sample analysis required under the Bioanalysis Plan, including [Redacted], 
(ii) conducting research directly related to the health condition under investigation pursuant to the Protocol and related diseases, (iii) 
using the BMS Compound and the Company Compound in disease therapy or diagnosis, and (iv) inspecting records or facilities relevant 
to the Combined Therapy Study.  Each Party agrees that it shall not disclose in any publication, information that would reveal the 
identity of a subject (such as name, photograph, social security number, telephone number or address), without the written consent of 
such subject.
(b)
Subject to the terms of this Agreement, and updated as necessary to maintain compliance with the Applicable 
Law, including the General Data Protection Regulation (EU) 2016/679 (the “GDPR”) during the Term, the Parties shall comply with the 
terms and conditions set forth under the Personal Data Processing Terms For Independent Controllers, attached hereto as Exhibit B.
 8.8.Destruction of Confidential Information.  Upon expiration or termination of the Agreement, the receiving Party shall, 
upon request by the other Party, immediately destroy or return all of the other Party’s Confidential Information relating solely to its 
Compound (but not to the Combined Therapy or the Combined Therapy Study data) in its possession; provided that the receiving Party 
shall be entitled to retain one (1) copy of Confidential Information solely for record-keeping purposes and shall not be required to 
destroy any off-site computer files created during automatic system back up which are subsequently stored securely by the receiving 
Party.

RIGHTS OR OBLIGATIONS OF A PARTY UNDER SECTION 10.1 OR SECTION 10.2, OR DAMAGES AVAILABLE FOR BREACHES OF 
CONFIDENTIALITY OBLIGATIONS IN ARTICLE 8.
Article 11.
Term and Termination
 11.1.Term.  This Agreement shall be effective as of the Effective Date and, unless earlier terminated pursuant to Section 
11.2(b), Section 11.2(c), Section 11.3, or any other termination right expressly provided for elsewhere in this Agreement, shall continue 
in effect until completion and delivery to both Parties of all case report forms, completion of the Statistical Analysis Plan analyses and all 
final clinical study reports contemplated by each Combined Therapy Study as described in the Protocol (the “Term”).
 11.2.Termination for Material Breach
(a)
Notice and Cure Period.  If a Party (the “Breaching Party”) is in material breach of this Agreement, the other 
Party (the “Non-Breaching Party”) shall have the right to give the Breaching Party notice specifying the nature of such material breach.  
The Breaching Party shall have a period of [Redacted] calendar days after receipt of such notice to cure such material breach (the “Cure

(b)
Termination Right.  The Non-Breaching Party shall have the right to terminate this Agreement upon written 
notice, in the event that the Breaching Party has not cured such material breach within the Cure Period, provided that if such breach is 
capable of cure but cannot be cured within the Cure Period despite the use of diligent efforts, and the Breaching Party notifies the Non-
Breaching Party of its intent to cure and commences actions to cure such material breach within the Cure Period and thereafter 
diligently continues such actions, the Breaching Party shall have an additional [Redacted] calendar days to cure such breach.  If a Party 

 
	
	
Page 38
contests such termination pursuant to the dispute resolution procedures under Section 12.3, such termination shall not be effective 
until a conclusion of the dispute resolution procedures in Section 12.3, as applicable, resulting in a determination that there has been a 
material breach that was not cured within the Cure Period (or, if earlier, abandonment of the dispute by such Party).
(c)
Termination for Bankruptcy.  Either Party may terminate this Agreement if, at any time, the other Party shall 
file in any court or agency pursuant to any statute or regulation of any state, country or jurisdiction, a petition in bankruptcy or 
insolvency or for reorganization or for an arrangement or for the appointment of a receiver or trustee of such other Party or of such 
other Party’s assets, or if the other Party proposes a written agreement of composition or extension of its debts, or if the other Party 
shall be served with an involuntary petition against it, filed in any insolvency proceeding, and such petition shall not be dismissed or 
stayed within [Redacted] calendar days after the filing thereof, or if the other Party will propose or be a party to any dissolution or 
liquidation, or if the other Party shall make an assignment for the benefit of its creditors.
 11.3.Termination Due to Material Safety Issue.  Either Party shall have the right to terminate this Agreement as applied to the 
Combined Therapy Study immediately upon written notice if it is necessary to protect the safety, health or welfare of subjects enrolled 
in the Combined Therapy Study due to the existence of a Material Safety Issue.  In the event of a termination due to a Material Safety 
Issue, prior to the terminating Party providing written notice, the Parties’ Executive Officers shall, to the extent practicable, meet and 
discuss in good faith the safety concerns raised by the terminating Party and consider in good faith the input, questions and advice of 
the non-terminating Party, but should any dispute arise in such discussion, [Redacted]
 11.4.Effect of Termination.  Upon expiration or termination of this Agreement (as a whole or with respect to the Combined 
Therapy Study), (a) the licenses granted to each Party to conduct the terminated Combined Therapy Study under Sections 3.1 and 3.2
shall terminate, and (b) the Parties shall use reasonable efforts to wind down activities under this Agreement with respect to the 
Combined Therapy Study in a reasonable manner and avoid incurring any additional expenditures or non-cancellable obligations; 
provided that the Company may continue to dose subjects enrolled in the Combined Therapy Study through completion of the Protocol 
if dosing is required by the applicable Regulatory Authority(ies) and/or Applicable Law(s).  Any such wind-down activities will include the 
return or destruction of all of BMS Compound provided by BMS and not consumed in the Combined Therapy Study.  If applicable, upon 
termination of this Agreement, the Parties shall remain responsible pursuant to the terms of this Agreement for any expenses incurred 
that are associated with terminating any ongoing clinical trial work and/or result from such ongoing activities under this Agreement 
solely to the extent such activities are deemed necessary by the Company (after discussion by the Parties) based on reasonable medical 
judgment to protect the health of subjects participating in the Combined Therapy Study.
 11.5.Survival.  The following Articles and Sections of this Agreement and all definitions relating thereto shall survive any 
expiration or termination of this Agreement for any reason: Article 5, Article 6, Article 7, Article 8, Article 9, Article 10, Article 12, 
Sections 4.2(b),  11.4 and this 11.5.
Article 12.
Miscellaneous
 12.1.Entire Agreement.  The Parties acknowledge that this Agreement shall govern all activities of the Parties with respect to 
the Combined Therapy Study from the Effective Date forward.  This Agreement, including the Exhibits hereto, together with the 
Protocol, the Supply and Quality Documentation and the Pharmacovigilance Agreement, sets forth the complete, final and exclusive 
agreement between the Parties concerning the subject matter hereof and supersedes all prior agreements and understandings between 
the Parties with respect to such subject matter.  There are no covenants, promises, agreements, warranties, representations, conditions 
or 

 
	
	
Page 39
understandings, either oral or written, between the Parties with respect to such subject matter other than as are set forth in this 
Agreement.  All Exhibits attached hereto are incorporated herein as part of this Agreement.
 12.2.Governing Law.  This Agreement shall be governed and construed in accordance with the internal laws of the State of 
New York, USA, excluding any choice of law rules that may direct the application of the laws of another jurisdiction.
 12.3.Dispute Resolution
(a)
In the event of any dispute, controversy or claim arising out of, relating to or in connection with any provision 
of this Agreement (each a “Dispute”), other than a JPT Dispute or a Publication Dispute or a dispute as to whether a Material Safety 
Issue exists, the Parties shall refer such Dispute promptly to the Alliance Managers for resolution.  If the Alliance Managers are unable to 
resolve such Dispute within [Redacted] calendar days after a matter has been presented to them, then upon the request of either Party 
by written notice, the Alliance Managers shall refer such Dispute to the Executive Officers.  This Agreement shall remain in effect during 
the pendency of any such Dispute.  In the event that no resolution is made by the Executive Officers in good faith negotiations within 
[Redacted] calendar days after such referral to them, then,
(i) with respect to matters under the operational authority of Company as provided in Section 2.1(m), such 
Dispute shall not be an Arbitration Matter, and Company shall have the final decision-making authority with regard to such Dispute;
(ii) if such Dispute is an Intellectual Property Dispute, a Publication Dispute or a dispute as to whether a 
Material Safety Issue exists, such Dispute shall not be an Arbitration Matter and shall be resolved in accordance with Section 5.6 with 
regard to an Intellectual Property Dispute, Section 8.5 with respect to a Publication Dispute, or Section 11.3 with respect to the 
existence of a Material Safety Issue; and
(iii) if such Dispute constitutes an Arbitration Matter, such Dispute shall be resolved through arbitration in 
accordance with Section 12.3; provided that either Party shall have the right to seek an injunction or other equitable relief in accordance 
with Section 12.4.
(b)
If a Dispute that constitutes an Arbitration Matter remains unresolved after escalation to the Executive Officers 
as described above, either Party may refer the matter to arbitration as described herein. Any arbitration under this Agreement shall be 
conducted under the auspices of the American Arbitration Association by a panel of three (3) arbitrators pursuant to that organization’s 
Commercial Arbitration Rules then in effect; provided that the Parties hereby agree that the time schedule for the appointment of 
arbitrators and the time schedule for submission of the statement of defense shall follow the American Arbitration Association 
Arbitration Rules.  The fees and expenses of the arbitrators shall be borne in equal shares by the Parties.  Each Party shall bear the fees 
and expenses of its legal representation in the arbitration.  The arbitral tribunal shall not reallocate either the fees or the expenses of 
the arbitrators or of the Parties’ legal representation.  The arbitration shall be held in New York, New York, USA, which shall be the seat 
of the arbitration.  The language of the arbitration shall be English.
 12.4.Injunctive Relief.  Notwithstanding anything herein to the contrary, a Party may seek an injunction or other injunctive 
relief from any court of competent jurisdiction in order to prevent immediate and irreparable injury, loss or damage on a provisional 
basis.  For the avoidance of doubt, if either Party (a) discloses Confidential Information of the other Party other than as permitted under 
Article 8, (b) uses (in the case of the Company) the BMS Compound or BMS Technology or (in the case of BMS) the Company Compound 
or Company Technology in any manner other than as expressly permitted under this Agreement or (c) otherwise is in material breach of 
this 

 
	
	
Page 40
Agreement and such material breach could cause immediate harm to the value of the Company Compound (by the Company) or the 
BMS Compound (by BMS), the other Party shall have the right to seek an injunction or other equitable relief precluding the other Party 
from continuing its activities related to the Combined Therapy Study without waiting for the conclusion of the dispute resolution 
procedures under Section 12.3.
 12.5.Force Majeure.  The Parties shall be excused from the performance of their obligations under this Agreement (other than
the payment of monies owed to the other Party) to the extent that such performance is prevented by force majeure and the non-
performing Party promptly provides notice of the prevention to the other Party.  Such excuse shall be continued so long as the condition 
constituting force majeure continues and the nonperforming Party takes reasonable efforts to remove the condition.  For purposes of 
this Agreement, force majeure shall mean acts of God, strikes or other concerted acts of workers, civil disturbances, fires, earthquakes, 
acts of terrorism, floods, explosions, riots, war, rebellion, sabotage or failure or default of public utilities or common carriers or similar 
conditions beyond the control of the Parties.
 12.6.Notices.  Any notice required or permitted to be given under this Agreement shall be in writing, shall specifically refer to 
this Agreement and shall be deemed to have been sufficiently given for all purposes if such notice is timely and is: (a) mailed by first 
class certified or registered mail, postage prepaid, return receipt requested, (b) sent by express delivery service, or (c) personally 
delivered.  Unless otherwise specified in writing, the mailing addresses of the Parties shall be as described below.

future law, and if the rights or obligations of a Party under this Agreement will not be materially and adversely affected thereby, (a) such 
provision shall be fully severable, (b) this Agreement shall be construed and enforced as if such illegal, invalid or unenforceable

or unenforceable provision, there shall be added automatically as a part of this Agreement a legal, valid and enforceable provision as 
similar in terms to such illegal, invalid or unenforceable provision as may be possible and reasonably acceptable to the Parties.

1.	
POLICY
I-Mab (the “Company”) is committed to maintaining the highest standards of business conduct and ethics. This Code of 
Business Conduct and Ethics (this “Code”) reflects the business practices and principles of behavior that support this 
commitment. We expect every employee, officer and director to read and understand this Code and its application to the 
performance of his or her business responsibilities. References in this Code to employees are intended to cover officers and, 
as applicable, directors. 
Officers, managers and other supervisors are expected to develop in employees a sense of commitment to the spirit, as well 
as the letter, of this Code. Supervisors are also expected to ensure that all agents and contractors conform to Code standards 
when working for or on behalf of the Company. The compliance environment within each supervisor’s assigned area of 
responsibility will be a factor in evaluating the quality of that individual’s performance. In addition, any employee who 
makes an exemplary effort to implement and uphold our legal and ethical standards may be recognized for that effort in his 
or her performance review. Nothing in this Code alters the at-will employment policy of the Company. 
This Code cannot possibly describe every practice or principle related to honest and ethical conduct. This Code addresses 
conduct that is particularly important to proper dealings with the people and entities with whom we interact, but reflects only 
a part of our commitment. From time to time we may adopt additional policies and procedures with which our employees, 
officers and directors are expected to comply, if applicable to them. However, it is the responsibility of each employee to 
apply common sense, together with his or her own highest personal ethical standards, in making business decisions where 
there is no stated guideline in this Code. 
Action by members of your family, significant others or other persons who live in your household (referred to in this Code as 
“family members”) also may potentially result in ethical issues to the extent that they involve the Company’s business. For 
example, acceptance of inappropriate gifts by a family member from one of our suppliers could create a conflict of interest 
and result in a Code violation attributable to you. Consequently, in complying with this Code, you should consider not only 
your own conduct, but also that of your family members, significant others and other persons who live in your household. 
You should not hesitate to ask questions about whether any conduct may violate this Code, voice concerns or clarify gray 
areas. Section 18 below details the compliance resources available to you. In addition, you should be alert to possible 
violations of this Code by others and report suspected violations, without fear of any form of retaliation, as further described 
in Section 18. Violations of this Code will not be tolerated. Any employee who violates the standards in this Code may be 
subject to disciplinary action, which, depending on the nature of the violation and the history of the 

Exhibit 11.1
POLICY

employee, may range from a warning or reprimand up to and including termination of employment and, in appropriate cases, 
civil legal action or referral for regulatory or criminal prosecution. 
2.	
HONEST AND ETHICAL CONDUCT.
It is the policy of the Company to promote high standards of integrity by conducting our affairs in an honest and ethical 
manner. The integrity and reputation of the Company depends on the honesty, fairness and integrity brought to the job by 
each person associated with us. Unyielding personal integrity is the foundation of corporate integrity. 
3.	
LEGAL COMPLIANCE. 
Obeying the law, both in letter and in spirit, is the foundation of this Code. Our success depends upon each employee 
operating within legal guidelines and cooperating with local, national and international authorities. We expect employees to 
understand the legal and regulatory requirements applicable to their business units and areas of responsibility. We hold or 
provide access to periodic training sessions or relevant education in order to ensure that all employees comply with the 
relevant laws, rules and regulations associated with their employment, including laws prohibiting insider trading (which are 
discussed in further detail in Section 4 below). While we do not expect you to memorize every detail of these laws, rules and 
regulations, we want you to be able to determine when to seek advice from others. If you do have a question in the area of 
legal compliance, it is important that you not hesitate to seek answers from your supervisor or the Chief Compliance Officer 
(as described in Section 18). Disregard of the law will not be tolerated. Violation of domestic or foreign laws, rules and 
regulations may subject an individual, as well as the Company, to civil and/or criminal penalties. You should be aware that 
conduct and records, including emails, are subject to internal and external audits, and to discovery by third parties in the 
event of a government investigation or civil litigation. It is in everyone’s best interests to know and comply with our legal 
and ethical obligations. 
4.	
INSIDER TRADING. 
Employees who have access to confidential (or “inside”) information are not permitted to use or share that information for 
stock trading purposes or for any other purpose except to conduct our business. All non-public information about the 
Company or about companies with which we do business is considered confidential information. To use material non-public 
information in connection with buying or selling securities, including “tipping” others who might make an investment 
decision on the basis of this information, is not only unethical, it is illegal. Employees must exercise the utmost care when 
handling material inside information. We have adopted a separate Insider Trading Policy (POL-0019) with which you will be 
expected to engage in the annual training policy as well as comply as a condition of your employment with the Company.

5.	
REGULATORY COMPLIANCE. 
The Company’s business is subject to, or may in the future be subject to, a number of legal and regulatory requirements, 
including standards related to ethical procedures and proper scientific conduct. We expect employees to comply with all such 
requirements. 
6.	
INTERNATIONAL BUSINESS LAWS. 
Our employees are expected to comply with the applicable laws in all countries to which they travel, in which they operate 
and where we otherwise do business, including laws prohibiting bribery, corruption or the conduct of business with specified 
individuals, companies or countries, per the Federal Corrupt Practices Act (FCPA) and the corresponding FCPA Policy 
(POL-0040). The fact that in some countries certain laws are not enforced or that violation of those laws is not subject to 
public criticism will not be accepted as an excuse for noncompliance. In addition, we expect employees to comply with U.S. 
laws, rules and regulations governing the conduct of business by its citizens and corporations outside the U.S. These U.S. 
laws, rules and regulations, which extend to all our activities outside the U.S., include: 
6.1.	 The FCPA, which prohibits directly or indirectly giving anything of value to a government official to obtain or retain 
business or favorable treatment, and requires the maintenance of accurate books of account, with all company 
transactions being properly recorded; 
6.2.	 U.S. Embargoes, which generally prohibit U.S. companies, their subsidiaries and their employees from doing business 
with, or traveling to, certain countries subject to sanctions imposed by the U.S. government (you can view a list here: 
https://ofac.treasury.gov/sanctions-programs-and-country-information), as well as specific companies and individuals 
identified on lists published by the U.S. Treasury Department; 
6.3.	 U.S. Export Controls, which restrict exports from the U.S. and re-exports from other countries of goods, software and 
technology to many countries, and prohibit transfers of U.S.-origin items to denied persons and entities; and 
6.4.	 Antiboycott Regulations, which prohibit U.S. companies from taking any action that has the effect of furthering or 
supporting a restrictive trade practice or boycott imposed by a foreign country against a country friendly to the U.S. or 
against any U.S. person. 
If you have a question as to whether an activity is restricted or prohibited, seek assistance before taking any action, including 
giving any verbal assurances that might be regulated by international laws.

7.	
ANTITRUST. 
Antitrust laws are designed to protect the competitive process. These laws are based on the premise that the public interest is 
best served by vigorous competition and will suffer from illegal agreements or collusion among competitors. Antitrust laws 
generally prohibit: 
	
agreements, formal or informal, with competitors that harm competition or customers, including price fixing and 
allocations of customers, territories or contracts;  
	
agreements, formal or informal, that establish or fix the price at which a customer may resell a product; and 
	
the acquisition or maintenance of a monopoly or attempted monopoly through anticompetitive conduct. 
Certain kinds of information, such as pricing, production and inventory, should not be exchanged with competitors, 
regardless of how innocent or casual the exchange may be and regardless of the setting, whether business or social. Antitrust 
laws impose severe penalties for certain types of violations, including criminal penalties and potential fines and damages of 
millions of dollars, which may be tripled under certain circumstances. Understanding the requirements of antitrust and unfair 
competition laws of the various jurisdictions where we do business can be difficult, and you are urged to seek assistance 
from your supervisor or the Chief Compliance Officer whenever you have a question relating to these laws. 
8.	
ENVIRONMENTAL COMPLIANCE. 
Federal law imposes criminal liability on any person or company that contaminates the environment with any hazardous 
substance that could cause injury to the community or environment. Violation of environmental laws can involve monetary 
fines and imprisonment. We expect employees to comply with all applicable environmental laws. 
It is our policy to conduct our business in an environmentally responsible way that minimizes environmental impacts. We are 
committed to minimizing and, if practicable, eliminating the use of any substance or material that may cause environmental 
damage, reducing waste generation and disposing of all waste through safe and responsible methods, minimizing 
environmental risks by employing safe technologies and operating procedures, and being prepared to respond appropriately 
to accidents and emergencies.
9.	
CONFLICTS OF INTEREST. 
We respect the rights of our employees to manage their personal affairs and investments and do not wish to impinge on their 
personal lives. At the same time, employees should avoid conflicts of interest that occur when their personal interests may 
interfere in any way with the performance of 

Exhibit 11.1
POLICY
Document Title:  Code of Conduct
Document Number: POL-0041
Revision Number: 02
 
 
 
their duties or the best interests of the Company. A conflicting personal interest could result from an expectation of personal 
gain now or in the future or from a need to satisfy a prior or concurrent personal obligation. We expect our employees to be 
free from influences that conflict with the best interests of the Company or might deprive the Company of their undivided 
loyalty in business dealings. Even the appearance of a conflict of interest where none actually exists can be damaging and
should be avoided. Whether or not a conflict of interest exists or will exist can be unclear. Conflicts of interest are prohibited 
unless specifically authorized as described below. If you have any questions about a potential conflict or if you become 
aware of an actual or potential conflict, and you are not an officer or director of the Company, you must discuss the matter 
with your supervisor or the Chief Compliance Officer. Supervisors may not authorize conflict of interest matters or make 
determinations as to whether a problematic conflict of interest exists without first seeking the approval of the Chief 
Compliance Officer and providing the Chief Compliance Officer with a written description of the activity. If the supervisor is 
involved in the potential or actual conflict, you should discuss the matter directly with the Chief Compliance Officer. 
Officers and directors must seek any authorizations and determinations from the Audit Committee (the “Audit Committee”) 
of the Board of Directors of the Company (the “Board”), depending on the nature of the conflict of interest. 
Factors that may be considered in evaluating a potential conflict of interest are, among others: 
	
whether it may interfere with the employee’s job performance, responsibilities or morale;
	
whether the employee has access to confidential information; 
	
any potential adverse or beneficial impact on our business; 
	
any potential adverse or beneficial impact on our relationships with our customers or suppliers or other service 
providers; 
	
whether it would enhance or support a competitor’s position; the extent to which it would result in financial or other 
benefit (direct or indirect) to the employee; 
	
the extent to which it would result in financial or other benefit (direct or indirect) to one of our customers, suppliers 
or other service providers; and 
	
the extent to which it would appear improper to an outside observer. 
Although no list can include every possible situation in which a conflict of interest could arise, the following are examples of 
situations that may, depending on the facts and circumstances, involve problematic conflicts of interests. 
Employment by (including consulting for) or service on the board of a competitor, customer or supplier or other service 
provider. Activity that enhances or supports the position of a competitor to the detriment of the Company is prohibited, 
including employment by or service on the board of a competitor. Employment by or service on the board of a customer or 
supplier or other service

provider is generally discouraged and you must seek authorization in advance if you plan to take such a position. 
Owning, directly or indirectly, a significant financial interest in any entity that does business, seeks to do business or 
competes with us. In addition to the factors described above, persons evaluating ownership in other entities for conflicts of 
interest will consider the size and nature of the investment; the nature of the relationship between the other entity and the 
Company; the employee’s access to confidential information; and the employee’s ability to influence the Company’s 
decisions. If you would like to acquire a financial interest of that kind, you must seek approval in advance. 
Soliciting or accepting gifts, favors, or any other benefit or benefits (including reputational), loans or preferential treatment 
from any person or entity that does business or seeks to do business with us. See Section 13 for further discussion of the 
issues involved in this type of conflict. 
Soliciting contributions for any charity or for any political candidate from any person or entity that does business or seeks to 
do business with us. 
Taking personal advantage of corporate opportunities. See Section 10 for further discussion of the issues involved in this 
type of conflict. 
Conducting our business transactions with your family member or a business in which you have a significant financial 
interest. Related-Party transactions covered by our Related-Party Transactions Policy (POL-0039) must be reviewed in 
accordance with such policy and will be publicly disclosed to the extent required by applicable laws and regulations. 
Exercising supervisory or other authority on behalf of the Company over a co-worker who is also a family member. The 
employee’s supervisor and/or the Compliance Officer will consult our Human Resources department to assess the 
advisability of reassignment. 
Loans to, or guarantees of obligations of, employees or their family members by the Company could constitute an improper 
personal benefit to the recipients of these loans or guarantees, depending on the facts and circumstances. Some loans are 
expressly prohibited by law, and applicable law requires that the Board approve all loans and guarantees to employees. As a 
result, all loans and guarantees by the Company must be approved in advance by the Board or the Audit Committee. 
10.	 CORPORATE OPPORTUNITIES. 
You may not take personal advantage of opportunities for the Company that are presented to you or discovered by you as a 
result of your position with us or through your use of corporate property or information, unless authorized by your 
supervisor, the Chief Compliance Officer or the Audit Committee, as described in Section 18. Even opportunities that are 
acquired privately by you may

be questionable if they are related to our existing or proposed lines of business. Participation in an investment or outside 
business opportunity that is directly competitive to our lines of business must be pre-approved. You may not use your 
position with the Company or our corporate property or information for improper personal gain, nor should you compete 
with us in any way. 
11.	 MAINTENANCE OF CORPORATE BOOKS, RECORDS, DOCUMENTS AND ACCOUNTS; FINANCIAL  
INTEGRITY; PUBLIC REPORTING. 
The integrity of our records and public disclosure depends upon the validity, accuracy and completeness of the information 
supporting the entries to our books of account. Therefore, our corporate and business records should be completed accurately 
and honestly. The making of false or misleading entries, whether they relate to financial results or test results, is strictly 
prohibited. Our records serve as a basis for managing our business and are important in meeting our obligations to customers, 
suppliers, creditors, employees and others with whom we do business. As a result, it is important that our books, records and 
accounts accurately and fairly reflect, in reasonable detail, our assets, liabilities, revenues, costs and expenses, as well as all 
transactions and changes in assets and liabilities. We require that: 
	
no entry be made in our books and records that intentionally hides or disguises the nature of any transaction or of 
any of our liabilities, or misclassifies any transactions as to accounts or accounting periods; 
	
transactions be supported by appropriate documentation; the terms of sales and other commercial transactions be
reflected accurately in the documentation for those transactions and all such documentation be reflected accurately 
in our books and records; 
	
employees comply with our system of internal controls; and 
	
no cash or other assets be maintained for any purpose in any unrecorded or “off-the-books” fund. 
Our accounting records are also relied upon to produce reports for our management, stockholders and creditors, as well as 
governmental agencies. In particular, we rely upon our accounting and other business and corporate records in preparing 
periodic and current reports that we file with the Securities and Exchange Commission (“SEC”). Securities laws require that 
these reports provide full, fair, accurate, timely and understandable disclosure and fairly present our financial condition and 
results of operations. Employees who collect, provide or analyze information for or otherwise contribute in any way in 
preparing or verifying these reports should strive to ensure that our financial disclosure is accurate and transparent and that 
our reports contain all of the information about the Company that would be important to enable stockholders and potential 
investors to assess the soundness and risks of our business and finances and the quality and integrity of our accounting and 
disclosures. In addition: 

Exhibit 11.1
POLICY
Document Title:  Code of Conduct
Document Number: POL-0041
Revision Number: 02
 
 
 
	
no employee may take or authorize any action that would intentionally cause our financial records or financial 
disclosure to fail to comply with generally accepted accounting principles, the rules and regulations of the SEC or 
other applicable laws, rules and regulations; 
	
all employees must cooperate fully with our Accounting Department, as well as our independent public accountants 
and counsel, respond to their questions with candor and provide them with complete and accurate information to 
help ensure that our books and records, as well as our reports filed with the SEC, are accurate and complete; and 
	
no employee should knowingly make (or cause or encourage any other person to make) any false or misleading 
statement in any of our reports filed with the SEC or knowingly omit (or cause or encourage any other person to 
omit) any information necessary to make the disclosure in any of our reports accurate in all material respects. 
Any employee who becomes aware of any departure from these standards has a responsibility to report his or her knowledge 
promptly to a supervisor, the Chief Compliance Officer, the Audit Committee, or one of the other compliance resources 
described in Section 18. 
12.	 FAIR DEALING. 
We strive to outperform our competition fairly and honestly through superior performance and not through unethical or 
illegal business practices. Acquiring proprietary information from others through improper means, possessing trade secret 
information that was improperly obtained, or inducing improper disclosure of confidential information from past or present 
employees of other companies is prohibited, even if motivated by an intention to advance our interests. If information is 
obtained by mistake that may constitute a trade secret or other confidential information of another business, or if you have 
any questions about the legality of proposed information gathering, you must consult your supervisor or the Chief 
Compliance Officer, as further described in Section 18. 
You are expected to deal fairly with our suppliers, employees and anyone else with whom you have contact in the course of 
performing your job. Be aware that the Federal Trade Commission Act provides that “unfair methods of competition in 
commerce, and unfair or deceptive acts or practices in commerce, are declared unlawful.” It is a violation of the Federal 
Trade Commission Act to engage in deceptive, unfair or unethical practices, and to make misrepresentations in connection 
with sales activities. 
Employees involved in procurement have a special responsibility to adhere to principles of fair competition in the purchase 
of products and services by selecting suppliers based exclusively on normal commercial considerations, such as quality, cost, 
availability, service and reputation, and not on the receipt of special favors.

13.	 GIFTS AND ENTERTAINMENT. 
Business gifts and entertainment are meant to create goodwill and sound working relationships and not to gain improper 
advantage with current or potential suppliers, vendors or partners or facilitate approvals from government officials. The 
exchange, as a normal business courtesy, of meals or entertainment (such as tickets to a game or the theatre or a round of 
golf) is a common and acceptable practice as long as it is not extravagant. Unless express permission is received from a 
supervisor, the Chief Compliance Officer or the Audit Committee, gifts and entertainment cannot be offered, provided or 
accepted by any employee unless consistent with customary business practices and not excessive in value. This principle 
applies to our transactions everywhere in the world, even where the practice is widely considered “a way of doing business.” 
Employees should not accept gifts or entertainment that may reasonably be deemed to affect their judgment or actions in the 
performance of their duties. 
Under some statutes, such as the U.S. Foreign Corrupt Practices Act (further described in Section 6), giving anything of 
value to a government official to obtain or retain business or favorable treatment is a criminal act subject to prosecution and 
conviction. Discuss with your supervisor or the Chief Compliance Officer any proposed entertainment or gifts if you are 
uncertain about their appropriateness. 
14.	 PROTECTION AND PROPER USE OF COMPANY ASSETS. 
All employees are expected to protect our assets and ensure their efficient use. Theft, carelessness and waste have a direct 
impact on our financial condition and results of operations. Our property, such as office supplies, computer equipment, 
products, laboratory supplies, and office or laboratory space are expected to be used only for legitimate business purposes, 
although incidental personal use may be permitted. 
You may not, however, use our corporate name, any brand name or trademark owned or associated with the Company or any 
letterhead stationery for any personal purpose. You may not, while acting on behalf of the Company or while using our 
computing or communications equipment or facilities, either: 
	
access the internal computer system (also known as “hacking”) or other resource of another entity without express 
written authorization from the entity responsible for operating that resource; or
	
commit any unlawful or illegal act, including harassment, libel, fraud, sending of unsolicited commercial email 
(also known as “spam”) in violation of applicable law, trafficking in contraband of any kind, or espionage. 

Exhibit 11.1
POLICY
Document Title:  Code of Conduct
Document Number: POL-0041
Revision Number: 02
 
 
 
If you receive authorization to access another entity’s internal computer system or other resource, you must make a 
permanent record of that authorization so that it may be retrieved for future reference, and you may not exceed the scope of 
that authorization. 
Unsolicited commercial email is regulated by law in a number of jurisdictions. If you intend to send unsolicited commercial 
email to persons outside of the Company, either while acting on our behalf or using our computing or communications 
equipment or facilities, you should contact your supervisor or the Chief Compliance Officer for approval. 
All data residing on or transmitted through our computing and communications facilities, including email and word 
processing documents, is the property of the Company and subject to inspection, retention and review by the Company, with 
or without an employee’s or third party’s knowledge, consent or approval, in accordance with applicable law. Any misuse or 
suspected misuse of our assets must be immediately reported to your supervisor or the Chief Compliance Officer. 
15.	 CONFIDENTIALITY. 
One of our most important assets is our confidential information. As an employee of the Company, you may learn of 
information about the Company that is confidential and proprietary. You also may learn of information before that 
information is released to the general public. Employees who have received or have access to confidential information should 
take care to keep this information confidential. Confidential information includes non-public information that might be of use 
to competitors or harmful to the Company or its suppliers, vendors or partners if disclosed, such as business, marketing and 
service plans, any financial information, product development, scientific data, manufacturing, laboratory results, designs, 
databases, customer lists, pricing strategies, personnel data, personally identifiable information pertaining to our employees, 
patients or other individuals (including, for example, names, addresses, telephone numbers and social security numbers), and 
similar types of information provided to us by our customers, suppliers and partners. This information may be protected by 
patent, trademark, copyright and trade secret laws. 
In addition, because we interact with other companies and organizations, there may be times when you learn confidential 
information about other companies before that information has been made available to the public. You must treat this 
information in the same manner as you are required to treat our confidential and proprietary information. There may even be 
times when you must treat as confidential the fact that we have an interest in, or are involved with, another company. 
You are expected to keep confidential information and proprietary information confidential unless and until that information 
is released to the public through approved channels (usually through a press release, an SEC filing or a formal 
communication from a member of senior management, as further described in Section 16). Every employee has a duty to 
refrain from disclosing to any person 

Exhibit 11.1
POLICY
Document Title:  Code of Conduct
Document Number: POL-0041
Revision Number: 02
 
 
 
confidential or proprietary information about us or any other company learned in the course of employment here, until that 
information is disclosed to the public through approved channels. This policy requires you to refrain from discussing 
confidential or proprietary information with outsiders and even with other Company employees, unless those fellow 
employees have a legitimate need to know the information in order to perform their job duties. Unauthorized use or 
distribution of this information could also be illegal and result in civil liability and/or criminal penalties. 
You should also take care not to inadvertently disclose confidential information. Materials that contain confidential 
information, such as memos, notebooks, computer disks and laptop computers, should be stored securely. Unauthorized 
posting or discussion of any information concerning our business, information or prospects on the Internet is prohibited, 
including on Internet forums, message boards, social media sites, “chat rooms” or blogs, regardless of whether you use your 
own name or a pseudonym. Be cautious when discussing sensitive information in public places like elevators, airports, 
restaurants and “quasi-public” areas within the Company, or in and around the Company’s facilities. All Company emails, 
voicemails and other communications are presumed confidential and should not be forwarded or otherwise disseminated 
outside of the Company, except where required for legitimate business purposes. 
In addition to the above responsibilities, if you are handling information protected by any privacy policy published by us, 
then you must handle that information in accordance with the applicable policy. 
16.	 MEDIA/PUBLIC DISCUSSIONS. 
It is our policy to disclose material information concerning the Company to the public only through specific limited channels 
to avoid inappropriate publicity and to ensure that all those with an interest in the Company will have equal access to 
information. All inquiries or calls from the press and financial analysts should be referred to our Chief Executive Officer or 
Chief Financial Officer. We have designated our Chief Executive Officer and Chief Financial Officer as our official 
spokespersons for questions concerning the financial performance, strategic direction or operating performance of the 
Company, and operational issues such as research and development, regulatory developments, sales and marketing, etc. 
Unless a specific exception has been made by our Chief Executive Officer or Chief Financial Officer, they are the only 
persons who may communicate with the press on behalf of the Company. You also may not provide any information to the 
media about us off the record, for background, confidentially or secretly, including, without limitation, by way of postings on 
internet websites, chat rooms or blogs.

17.	 WAIVERS. 
Any waiver of this Code for executive officers (including, where required by applicable laws, our principal executive officer, 
principal financial officer, principal accounting officer or controller (or persons performing similar functions)) or directors 
may be authorized only by our Board or, to the extent permitted by the rules of The Nasdaq Stock Market, a committee of the 
Board, and will be disclosed as required by applicable laws, rules and regulations.
18.	 COMPLIANCE STANDARDS AND PROCEDURES. 
To facilitate compliance with this Code, we have implemented a program of Code awareness, training and review that is part
of our broader compliance programs overseen by our Audit Committee. We have established the position of Chief 
Compliance Officer which is currently held by the Chief Financial Officer to oversee this program. The Chief Compliance 
Officer is a person to whom you can address any questions or concerns related to this Code or any other matters relating to 
legal or regulatory compliance. The Chief Compliance Officer is our Chief Financial Officer. In addition to fielding 
questions or concerns with respect to potential violations of this Code or any other matters relating to legal or regulatory 
compliance, the Chief Compliance Officer is responsible for: 
	
investigating possible violations of this Code; 
	
training new employees in Code policies; 
	
conducting annual training sessions to refresh employees’ familiarity with this Code; 
	
distributing copies of this Code annually via email to each employee with a reminder that each employee is 
responsible for reading, understanding and complying with this Code; 
	
updating this Code as needed and alerting employees to any updates, with appropriate approval of the Audit 
Committee, to reflect changes in the law, the Company’s operations and in recognized best practices, and to reflect 
the Company’s experience; 
	
overseeing the Company’s compliance program and reporting to the Audit Committee material matters that may 
arise relating to the Company’s legal and regulatory compliance efforts; and 
	
otherwise promoting an atmosphere of responsible and ethical conduct. 
Your most immediate resource for any matter related to this Code is your supervisor. He or she may have the information 
you need or may be able to refer the question to another appropriate source. There may, however, be times when you prefer 
not to go to your supervisor. In these instances, you should feel free to discuss your concern with the Chief Compliance 
Officer. If you are uncomfortable speaking with the Chief Compliance Officer because he or she works in your department or 
is one of your supervisors, please contact the Chief Executive Officer. A toll-free compliance hotline is also available to 
those who wish to ask questions about the Company’s policy, seek guidance on specific 

Exhibit 11.1
POLICY
Document Title:  Code of Conduct

situations, submit concerns regarding questionable accounting or auditing matters or report violations of this Code. The toll-
free compliance hotline is 1-800-289-5053. You may call the toll-free number although the Chief Compliance Officer will be 
unable to obtain follow-up details from you that may be necessary to investigate the matter. Whether you identify yourself or 
remain anonymous, your contact with the toll-free compliance hotline will be kept strictly confidential to the extent 
reasonably possible within the objectives of this Code. 
Clarifying Questions and Concerns; Reporting Possible Violations 
If you encounter a situation or are considering a course of action and its appropriateness is unclear, discuss the matter 
promptly with your supervisor or the Chief Compliance Officer; even the appearance of impropriety can be very damaging 
and should be avoided. 
If you are aware of a suspected or actual violation of Code standards by others, you have a responsibility to report it. You are 
expected to promptly provide a compliance resource with a specific description of the violation that you believe has 
occurred, including any information you have about the persons involved and the time of the violation. Whether you choose 
to speak with your supervisor or the Chief Compliance Officer, you should do so without fear of any form of retaliation. We 
will take prompt disciplinary action against any employee who retaliates against you, up to and including termination of 
employment. 
Supervisors must promptly report any complaints or observations of Code violations to the Chief Compliance Officer. If you 
believe your supervisor has not taken appropriate action, you should contact the Compliance Officer directly. The Chief 
Compliance Officer will investigate all reported possible Code violations promptly and with the highest degree of 
confidentiality that is possible under the specific circumstances. Neither you nor your supervisor may conduct any 
preliminary investigation, unless authorized to do so by the Chief Compliance Officer. Your cooperation in the investigation 
will be expected. As needed, the Chief Compliance Officer will consult with our outside legal counsel and/or the Audit 
Committee. It is our policy to employ a fair process by which to determine violations of this Code. 
With respect to any complaints or observations of Code violations, including, but not limited to, matters that may involve 
accounting, internal accounting controls and auditing concerns, the Chief Compliance Officer shall promptly inform the chair 
of the Audit Committee, and the Audit Committee or such other persons as the Audit Committee determines to be 
appropriate under the circumstances shall be responsible for supervising and overseeing the inquiry and any investigation 
that is undertaken. In addition, any matters involving accounting, internal accounting controls and auditing concerns that are 
reported via the toll-free compliance hotline or compliance email address shall be routed to both the Chief Compliance 
Officer and the Chairman of the Audit Committee. If 

Exhibit 11.1
POLICY

Document Number: POL-0041
Revision Number: 02
 
 
 
any investigation indicates that a violation of this Code has probably occurred, we will take such action as we believe to be 
appropriate under the circumstances. If we determine that an employee is responsible for a Code violation, he or she will be 
subject to disciplinary action up to, and including, termination of employment and, in appropriate cases, civil legal action or 
referral for regulatory or criminal prosecution. Appropriate action may also be taken to deter any future Code violations.

Exhibit 11.2
POLICY
Document Title:  Insider Trading Policy
Document Number: POL-0019
Revision Number: 02
 
 
 
1.	
PURPOSE
This policy is intended to prevent improper trading in any Securities of I-MAB or in Securities of I-MAB's business partners. 
It is also intended to provide guidelines to ensure that all directors, officers, and employees of I-MAB and its subsidiaries and 
affiliated entities (collectively, "the Company") act in accordance with the laws and regulations applicable for prevention of 
insider trading. It is the policy of the Company to comply with all insider trading laws and regulations.
2.	
SCOPE
This policy applies to all directors, officers, employees, and agents of the Company.
3.	
RESPONSIBILITY
Finance will communicate the Insider Trader Policy to all in-scope parties and administer the preclearance process.
4.	
ABBREVIATIONS AND DEFINITIONS
The following are the abbreviations and definitions as used in this document:
4.1.	 Blackout Periods. A specified period during which the identified directors, officers, and employees of the Company are 
prohibited from transacting in the Company's Securities. Blackout Periods are the Company's internal policy which 
supplements the regulations and rules regarding Insider Trading.
4.2.	 Material Non-Public Information. Information about the Company is "Material” if it could be reasonably expected to 
affect the investment or voting decisions of a shareholder or investor, or if the disclosure of the information could be 
reasonably expected to significantly alter the total mix of information in the marketplace about the Company. In simple 
terms, Material Information is any type of information that could be reasonably expected to affect the market price of 
the Company's securities. Both positive and negative information may be Material. While it is not possible to identify 
all information that would be deemed "Material”, the following items are types of information that should be considered 
carefully to determine whether they are material.
•	
Information related to filings by the Company or decisions by regulatory authorities regarding the 
Company's drug candidates;
•	
Information related to clinical trials or the expected timing of announcing the results of such trials;
•	
Projections of future earnings or losses, or other earnings guidance;
•	
Earnings or revenue that are inconsistent with the consensus expectations of the 

Exhibit 11.2
POLICY

investment community;
•	
Potential restatements of the Company's financial statements, changes in auditors or auditor notification 
that the Company may no longer rely on an auditor's audit report;
•	
Pending or proposed strategic transactions, mergers, acquisitions, tender offers, joint ventures or 
dispositions of significant assets;
•	
Changes in management or the Board;
•	
Actual or threatened litigation or governmental investigations or major developments in such matters;
•	
Developments regarding drug candidates, customers, suppliers, orders, contracts or financing sources 
(e.g., the entering into or termination of a contract;)
•	
Changes in dividend policy, declarations of share splits, or public or private sales of additional 
securities;
•	
Potential defaults under the Company’s credit agreements or indentures, or the existence of material 
liquidity deficiencies; and
•	
Bankruptcies or receiverships.
The U.S. Securities and Exchange Commission (the "SEC") has stated that there is no fixed quantitative threshold 
amount for determining materiality, and that even very small quantitative changes can be qualitatively material if they 
would result in a movement in the price of the Company's securities.
Material information is "Non-public" if it has not been disseminated in a manner making it available to investors 
generally. To show that information is public, it is necessary to point to some fact that establishes that the information 
has become publicly available, such as the filing of a report with the SEC, the distribution of a press release through a 
widely disseminated news or wire service, or by other means that are reasonably designed to provide broad public 
access. Before a person who possesses Material Non-public Information can trade, there also must be adequate time for 
the market as a whole to absorb the information that has been disclosed. For the purposes of this Insider Trading Policy, 
information will be considered public after the close of trading on the first full trading day following the Company's 
public release of the information (i.e., if information is disclosed after trading begins on Monday, the information will 
not be considered public until after the close of trading on Tuesday).
4.3.	 Insider. Any person who has regular access to Material Non-Public Information relating to I­MAB Securities. In I-
MAB, Deemed Insiders include all Directors and Officers as defined in the Company's Form 20-F, employees of the 
Company and/or its subsidiaries at the level of VP or above, members of the company's accounting, finance or investor 
relation teams. The prohibitions outlined in this Insider Trading Policy also apply to your family members who reside 
with you, including your spouse, minor children, anyone else living in your home, any

family members who do not live in your home but whose transactions in Company securities or securities of the 
companies with which it does business are directed by you or are subject to your influence or control (such as parents or 
children who consult with you before they trade in Company securities) and any entities under your control. The 
Company will hold you responsible for the conduct of these other persons or entities. Therefore, you should make them 
aware of the need to confer with you before they trade in the Company's securities or, if applicable, securities of the 
companies with which it does business.
4.4.	 Deemed Insider. Any person who has regular access to Material Non-Public Information relating to I­MAB Securities. 
In I-MAB, Deemed Insiders include all Directors and Officers as defined in the Company's Form 20-F, employees of 
the Company and/or its subsidiaries at the level of VP or above, members of the company's accounting, finance or 
investor relation teams.
The prohibitions outlined in this Insider Trading Policy also apply to your family members who reside with you, 
including your spouse, minor children, anyone else living in your home, any family members who do not live in your 
home but whose transactions in Company securities or securities of the companies with which it does business are 
directed by you or are subject to your influence or control (such as parents or children who consult with you before they 
trade in Company securities) and any entities under your control. The Company will hold you responsible for the 
conduct of these other persons or entities. Therefore, you should make them aware of the need to confer with you before 
they trade in the Company's securities or, if applicable, securities of the companies with which it does business.
4.5.	 Insider Trading. Buying or selling a security while in possession of Material Non-Public Information.
4.6.	 SEC. United States Securities and Exchange Commission

Shares (or ADRs), options, employee savings plans holding shares, or other securities of the Company.
5.	
POLICY
5.1.	 Trading and Tipping Prohibitions. Any I-MAB directors, officers and employees in possession of Material Non-
Public Information is obliged, as an Insider, to comply with the applicable laws and regulations on Insider Trading. 
Hence an Insider is bound by a duty to prohibit any transaction on I-MAB Securities so long as Material Non-Public 
Information is not made public. Insiders owe also to I-MAB a duty of confidentiality in respect of such Material Non-
Public Information. Disclosing Material Non-Public Information, recommending 

Exhibit 11.2
POLICY

buying or selling Securities on the basis of such Material Non-Public Information and tipping are also prohibited.
5.2.	 Blackout Periods. I-MAB applies certain Blackout Periods preceding the publication of financial results, or Material 
Non­Public Information to reduce the risk of inadvertent Insider Trading by the Insiders. If a Blackout Period applies to 
I-MAB directors, officers or employees, such person will be informed of this once the dates for the publication of 
financial results, or Material Non-public Information are established. Please refer to the following table for details of 
Blackout Periods.

5.3.	 Prohibited Transactions. When you know or are in possession of Material Non-Public information about the 
Company, you generally are prohibited from the following activities:
	
Trading in the Company's securities, which includes ordinary shares, any other type of securities that  the  
Company  may  issue  (such  as  preferred  shares,  convertible  debentures,  warrants, exchange-traded 
options or other derivative securities), and any derivative securities that provide the economic equivalent 
of ownership of any of the Company's securities or an opportunity, direct or indirect, to profit from any 
change in the value of the Company's securities. "Trading" includes , any acquisition, disposal or transfer 
of, or offer to acquire, dispose of or transfer, or creation of pledge, charge or any other security interest in, 
any securities of the Company or any entity 

Exhibit 11.2
POLICY
Document Title:  Insider Trading Policy
Document Number: POL-0019
Revision Number: 02
 
 
 
whose assets solely or substantially comprise securities of the Company, and the grant, acceptance, 
acquisition, disposal, transfer, exercise or discharge of any option (whether call, put or both) or other right
or obligation, present or future, conditional or unconditional, to acquire, dispose of or transfer securities, or 
any interest in securities, of the Company or any such entity, in each case whether or not for consideration 
and any agreements to do any of the foregoing, and "trade" shall be construed accordingly;
	
Having others trade for you in the Company's securities;
	
Giving trading advice of any kind about the Company except that you should, when appropriate, advise 
others not to trade if doing so might violate the law or this Insider Trading Policy; and
	
Disclosing the Material Non-Public information about the Company to anyone else who might then trade, 
or recommending to anyone that they purchase or sell the Company's securities when you are aware of 
Material Non-Public information (these practices are known as "tipping").
As noted above, for purposes of this Insider Trading Policy, trading securities excludes the acceptance of options or 
other share-based awards granted by the Company and the exercise of options or vesting of other share-based awards 
that does not involve the sale of securities. Among other things, the cashless exercise of options does involve the sale of 
securities and therefore is subject to this Insider Trading Policy.
This Insider Trading Policy and the guidelines described herein also apply to Material Non-Public information relating 
to other companies, including the Company’s partners, customers and suppliers ("Business Partners"), particularly when 
that information is obtained in the course of employment with, or other services performed by, or on behalf of, the 
Company. Civil and criminal penalties, and discipline, including termination of employment for cause, may result from 
trading on Material Non-Public Information regarding the Company's Business Partners. Everyone should treat Material 
Non­Public Information about the Company's Business Partners with the same care required with respect to information 
related directly to the Company.
5.4.	 Specific Rules. Insider Trading rules should be taken into account for any portfolio switching between units of 
investment funds exclusively invested in I-MAB securities and other types of plan asset. This Insider Trading Policy 
applies to the use of outstanding Company securities to constitute part or all of the exercise price of an option or 
warrant, any sale of shares as part of a broker-assisted cashless exercise of an option or warrant, or any other market 
sale for the purpose of generating the cash needed to pay the exercise price of an option or warrant or the withholding 
tax due upon vesting of restricted shares or restricted share units.

5.5.	 Preclearance. For Deemed Insiders, any purchase or sale orders involving any ADSs, ordinary shares or other 
securities of the Company on the open market or by private transactions, or a combination of the foregoing, or entering 
into a binding security trading plan must be pre-cleared by the Company's CFO. To complete the preclearance process, 
participants first email the Company’s dedicated mailbox (pre-clearance@imabbio.com), notifying the Company of 
their intent to transact in the Company’s securities. The participant should utilize the following template when 
submitting their request:
 I, employee name (employee ID), am writing to request a nominee share sale referring to my ADSs held under the Vested Share 
Award.
Transaction details as below:
Request Date & Time
 
Sale units (in ADS)
 
Order type
 
I confirm that I understand and agree to submit the online sale order with exact details matched with the approval result provided 
by I-Mab, if the order is approved/partially approved.
If approval is granted, the participant has two days from the preclearance approval date to execute the trade.
For I-MAB's officers, employees, consultants and agents other than Deemed Insiders, any purchase or sale orders 
involving any ADSs, ordinary shares or other securities of the Company or entering a binding security trading plan are 
not allowed while in possession of Material Non-public Information relating to the Company or its ADSs, ordinary 
shares or other securities. If you are uncertain on the pending trading of the Company's ADSs, ordinary shares or other 
securities, or any written trading plans, please contact the Company’s CFO for pre-clearance.
5.6.	 Confidentiality. No director, officer, employee, consultant or agent of the Company may communicate any Material 
Non-Public Information to anyone outside the Company under any circumstances unless approved by the Company’s 
CFO in advance, or to anyone within the Company other than on a need-to-know basis. No director, officer, employee, 
consultant or agent of the Company may discuss any internal matters or developments of the Company with anyone 
outside the Company, except as required for the performance of regular corporate duties. Unless you are expressly 
authorized to the contrary, if you receive any inquiries about the Company or its securities by the financial press, 
research analysts or others, or any requests for comments or interviews, you are required to decline comment and direct 
the inquiry or request to the Company's CFO, who is responsible for coordinating and overseeing the release

of information of the Company to the investing public, analysts and others in compliance with applicable laws and 
regulations.
5.7.	 Responsibilities. Directors, officers, employees, consultants and agents of the Company may create, use or have access 
to Material Non-Public Information about the Company, or a company with which it does business, that is not generally 
available to the investing public. Everyone has an important ethical and legal obligation to maintain the confidentiality 
of such information and not to engage in any transactions in the Company's securities or, if applicable, securities of the 
companies with which they do business while in possession of Material Non-Public Information. Each individual and 
the Company may be subject to severe civil and criminal penalties as a result of unauthorized disclosure of or trading in 
the Company's securities or, if applicable, securities of the companies with which it does business while in possession 
of Material Non-Public Information. Each director, officer, employee, consultant or agent of the Company understands 
that the responsibility for determining whether he or she possesses Material Non-Public Information rests with such 
individual and that pre-approval of a transaction does not constitute legal advice or insulate such individual from 
liability under the securities laws.
Penalties for trading on or tipping Material Non-Public Information can extend significantly beyond any profits made or 
losses avoided, both for individuals engaging in the unlawful conduct and their employers. The SEC and the United 
States Department of Justice have made the civil and criminal prosecution of insider trading violations a top priority. 
Enforcement remedies available to the government or private plaintiffs under the U.S. federal securities laws include:
	
Administrative sanctions;
	
Sanctions by self-regulatory organizations in the securities industry;
	
Civil injunctions;
	
Damage awards to private plaintiffs; 
	
Disgorgement of profits gained by the violator;
	
Civil fines for the violator of up to three times the amount of profit gained or loss avoided by the violator;
	
Civil fines for the employer or other controlling person of a violator (i.e., where the violator is an 
employee or other controlled person) of up to the greater of US$1,000,000 or three times the amount of 
profit gained or loss avoided by the violator;
	
Criminal fines for individual violators of up to US $5,000,000(US $25,000,000for an entity); and Jail 
sentences of up to 20 years.

In addition, insider trading could result in serious sanctions by the Company, including immediate dismissal. Insider 
trading violations are not limited to violations of the U.S. federal securities laws. Other U.S. federal and state civil or 
criminal laws, such as the laws prohibiting mail and wire fraud and the Racketeer Influenced and Corrupt Organizations
Act (RICO), also may be violated upon the occurrence of insider trading.
If Material Non-Public Information is inadvertently disclosed by any director, officer, employee, consultant or agent to a 
person outside the Company who is not obligated to keep the information confidential you should immediately report all 
the facts to the Company’s CFO, so that the Company may take appropriate remedial action. Under SEC rules, the 
Company generally has only 24 hours after learning of an inadvertent disclosure of Material Non-Public Information to 
publicly disclose such information.
