 Bing Li 

Dear Bing: 
 As we discussed on January 13,
2021, and pursuant to Section 9 of the Executive Employment Agreement between you and LianBio, an exempted company organized under the laws of the Cayman Islands (the “Company”), dated September 26, 2019 (the
“Employment Agreement”), we hereby give formal notice to you that, your employment with the Company shall terminate, effective as of March 26, 2021 (the “Termination Date”). The purpose of this letter (the
“Agreement”) is to confirm the terms concerning the termination of your employment. Capitalized terms not defined herein shall have the respective meanings ascribed to them in the Employment Agreement. 

1. Notice Period and Resignation from the Board and Company Positions. 

(a) Effective as of today, February 24, 2021 (the “Notice Date”), you will be placed on a paid leave of absence that will
continue through the Termination Date in accordance with Section 9 of the Employment Agreement. The period beginning on the Notice Date and concluding on the Termination Date is hereinafter referred to as the “Notice Period”.
During the Notice Period, the Company will continue to pay you your base salary at the same rate and in the same manner in effect as of the date hereof, and to participate in all employee benefit plans of the Company accordance with the terms of
those plans (to the extent applicable), except that you will no longer be entitled to receive an annual bonus or the fringe benefits set forth on Schedule 2 of the Employment Agreement, and you will not incur any business expenses during the Notice
Period without the advance approval of the board of directors of the Company (the “Board”). During the Notice Period, you will not be expected to report to the Company’s offices, and will perform only such duties as may be
assigned to you from time to time by the Board, or its expressly-authorized designee. It is presently anticipated that during the Notice Period, the Company will request no services from you other than episodic assistance in transitioning your
current duties and responsibilities to any Company designees, as well as in cooperating with any governmental investigation, internal investigation, litigation or regulatory or other proceeding in accordance with Section 6(d) below, and that
you will otherwise be free during the Notice Period to pursue other employment opportunities, subject to your Continuing Obligations (as defined below). During the Notice Period, you will (i) not hold yourself out to 

 
any third party as representing the Company on any matter affecting the business of the Company, (ii) immediately refer any inquiries, requests or other communications you may receive
concerning such matters to the Board or its expressly-authorized designee, and (iii) not initiate contact with any person or entity that is known (or should be known) by you to be an employee, consultant, customer or other business relation of
the Company, for any reason related to the Company or its business, without the express approval of the Board or its expressly-authorized designee. Further, the Company may terminate your employment for Cause (as defined in the Employment Agreement)
at any time during the Notice Period upon notice to you. If the Company terminates your employment for Cause, you will not be eligible to receive any further payments of any sort from the Company (including the severance benefits described in
Section 3 below), other than any unpaid compensation through the Termination Date. It is understood and agreed that the paid leave of absence contemplated in this Agreement will not constitute “Good Reason” for purposes of the
Employment Agreement. 
 (b) As of the Termination Date, you will be deemed to have resigned from any and all positions, offices, or
memberships that you held with the Company or on any boards of directors or other governing boards of the Company or those Affiliates, including but not limited to the general managers, authorized signatories, legal representatives and other similar
positions of any direct or indirect subsidiary of the Company, the Board, and any and all memberships you held on any of the committees of any such boards, without any further action required therefor (collectively, the
“Resignations”). The Company, on its own behalf and on behalf of its Affiliates, hereby accepts the Resignations as of the Termination Date (the “Resignation Date”), and you agree to sign and return such documents
confirming the Resignations as the Company or any of its Affiliates may reasonably require. For the avoidance of doubt, you agree to (i) execute any such forms, letters, certificates, powers of attorney, instruments and documents necessary or
reasonable to effect such your Resignations, including, without limitation, registration forms to be submitted to the PRC State Administration for Market Regulation or any other applicable governmental and regulatory authorities with respect to your
Resignations (collectively, the “Removal Documents”) and (ii) deliver the Removal Documents to the designee of the Company. The Company shall use commercially reasonable efforts to effect your Resignations, including completion
of registrations with all governmental and regulatory authorities, in a timely manner. It is understood and agreed that the Company and its Affiliates have taken and will take actions in reliance on the Resignations and that the Resignations will
become irrevocable on the Resignation Date. 
 2. Final Compensation. You will
receive on the Termination Date, all salary and pay for all work you performed for the Company through the Termination Date, to the extent not previously paid. You will receive the payments described in this Section 2 regardless of whether or
not you sign this Agreement. 
 3. Severance Benefits. In consideration of your acceptance of this Agreement and subject to your
meeting in full your obligations hereunder, and in full consideration of any rights you may have under the Employment Agreement, the Company will pay you the Severance Payment in accordance with
Section 11.2 of the Employment Agreement. The Severance Payment is an amount equal to your salary, at the same rate and in the same manner in effect as of the date hereof, for a period of twelve (12) months following the Termination Date.
Payments will be made in the form of salary continuation, and will begin no later than seven (7) days following the Termination Date. The first payment will be retroactive to the day following the Termination Date. For the avoidance of doubt, the
Severance Payment does not include any fringe benefits referenced in the Employment Agreement (including those set forth on Schedule 2 thereto) which you do not currently receive because you have elected not to participate in such benefit offerings.

 4. Acknowledgement of Full Payment and Withholding.  

(a) You acknowledge and agree that the payments provided under Sections 1, 2 and 3 of this Agreement are in complete satisfaction of any
and all compensation or benefits due to you from the Company, whether for services provided to the Company under the Employment Agreement or otherwise, through the Termination Date and that, except as expressly provided under this Agreement, no
further compensation or benefits are owed or will be provided to you by the Company. 
 (b) All payments made by the Company under this
Agreement shall be reduced by any tax or other amounts required to be withheld by the Company under applicable law and all other lawful deductions authorized by you. 

5. Status of Employee Benefits and Expenses. 

(a) Employee Benefits. Your participation in all employee benefit plans of the Company will end as of the Termination Date, in
accordance with the terms of those plans. 
 (b) Expenses. Within two (2) weeks following the Notice Date, you must submit your
final expense reimbursement statement reflecting all business expenses you incurred through the Notice Date, if any, for which you seek reimbursement, and, in accordance with Company policy, reasonable substantiation and documentation for the same.
The Company will reimburse you for your authorized and documented expenses no later than seven (7) days following the Termination Date. 

(c) Stock Options. As of the Termination Date, you hold options (the “Options”) to acquire a total of 342,000
ordinary shares of the Company (“Shares”) pursuant to (i) a Share Option Grant Notice by and between you and the Company dated January 1, 2020 (the “First 2020 Option Award”) and (ii) a Non-Statutory Stock Option Agreement by and between you and the Company effective as of December 17, 2020 (the “Second 2020 Option Award” and together with the 2020 Option Award, the
“Option Awards”), which Options are subject to the Company’s 2019 Equity Incentive Plan (the “Equity Incentive Plan”). You acknowledge and agree that, if prior to the date hereof, you have not executed the
Non-Statutory Stock Option Agreement evidencing the Second 2020 Option Award, you shall do so concurrently with your execution of this Agreement. As of the Termination Date, the Options will be vested as to
228,000 Shares, which vested portion of the Options shall remain subject to the applicable Option Award, the Equity Incentive Plan, and any other agreements or other requirements applicable to such Options. All Options which are unvested as of
the Termination Date have been cancelled as of that date, and you agree to return, no later than the Effective Date of this Agreement, the stock option certificates for all Options granted you which were unvested on

  
 -3- 

 
the Termination Date. The vested portion of the Options must be exercised not later than six (6)-months following the Termination Date, and, to the extent not exercised during such period,
shall immediately and automatically terminate on the six (6)-month anniversary of the Termination Date with no consideration due to you. If you choose to exercise all or any portion of the Options, you agree that, without limiting any other
provisions in favor of the Company contained in the Option Awards or the Plan, the Shares acquired thereunder shall be subject to Sections 9 and 10 of the Company’s Second Amended and Restated Shareholders Agreement, as the same may be further
amended and restated from time to time, and you agree to execute all agreements requested by the Company to effectuate the forgoing. You acknowledge and agree that, if any portion of the Options was granted as an incentive stock option under
the U.S. Internal Revenue Code of 1986, as amended, as a result of the provisions of this Agreement, it shall cease to be so and the Company shall have no liability with respect to the foregoing. 

6. Continuing Obligations, Confidentiality and Non-Disparagement.  

(a) Subject to Section 8(c) of this Agreement, you acknowledge that you continue to be bound by your obligations under the Compliance
Agreement between you and the Company dated as of September 26, 2019 (the “Compliance Agreement”) and the Option Awards, as well as any other obligations or provisions under the Employment Agreement that survive the termination
of your employment by necessary implication or the terms thereof (collectively, the “Continuing Obligations”). For the avoidance of doubt, you will not be held criminally or civilly liable under any federal or state trade secret law
for disclosing a trade secret (y) in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney, solely for the purpose of reporting or investigating a suspected violation of law, or
(z) in a complaint or other document filed under seal in a lawsuit or other proceeding; provided, however, that notwithstanding this immunity from liability, you may be held liable if you unlawfully access trade secrets by
unauthorized means. 
 (b) Subject to Section 8(c) of this Agreement, you agree that you will not disclose this Agreement or any of its
terms or provisions, directly or by implication, except to members of your immediate family and/or to your legal and tax advisors on the condition that they agree and undertake not to further disclose this Agreement or any of its terms or provisions
to others. 
 (c) Subject to Section 8(c) of this Agreement, you agree that you will not disparage or criticize any of the Released
Parties (as defined below), the Company, its Affiliates, their business, their management or their products or services, and that you will not otherwise do or say anything that could disrupt the good morale of employees of the Company or any of its
Affiliates or harm the interests or reputation of the Company or any of its Affiliates. 
 (d) You agree to cooperate with the Company and
its Affiliates hereafter with respect to all matters arising during or related to your employment, including but not limited to all matters in connection with any governmental investigation, internal investigation, litigation or regulatory or other
proceeding which may have arisen or which may arise following the signing of this Agreement. The Company will reimburse your out-of-pocket expenses incurred in complying
with Company requests hereunder, provided such expenses are authorized by the Company in advance. 

  
 -4- 

 7. Return of Company Documents and Other Property. In signing this Agreement and in
accordance with Section 1(c)(4) of the Compliance Agreement, you represent and warrant that you have returned to the Company any and all documents, materials and information (whether in hardcopy, on electronic media or otherwise) related to the
business of the Company and its Affiliates (whether present or otherwise), and all chops, seals, certificates, bank USB-keys (with their passwords), office keys, access cards, credit cards, computer hardware
and software, telephones and telephone-related equipment and all other property of the Company or any of its Affiliates in your possession or control, and that you have signed and delivered to the Company the Termination Certificate attached to the
Compliance Agreement as Exhibit A. Further, you represent and warrant that you have not retained any copy or derivation of any documents, materials or information (whether in hardcopy, on electronic media or otherwise) of the Company or any of its
Affiliates, except that, for the avoidance of doubt, you may retain copies of your Employment Agreement, the Compliance Agreement and this Agreement. Recognizing that your active employment with the Company has ended as of the Notice Date, you agree
that you have not, since the Notice Date, for any purpose, other than for performance of this Agreement, attempted to access or use any computer or computer network or system of the Company or any of its Affiliates, including without limitation the
electronic mail system, and you agree that you will not do so. Further, you acknowledge that you have disclosed to the Company any and all passwords necessary or desirable to obtain access to, or that would assist in obtaining access to, all
information which you have password-protected on any computer equipment, network or system of the Company or any of its Affiliates. 
 8.
General Release and Waiver of Claims. 
 (a) In exchange for the severance pay and benefits provided to you under this Agreement, to
which you would not otherwise be entitled, and other good and valuable consideration, the receipt and sufficiency of which you hereby acknowledge, on your own behalf and that of your heirs, executors, administrators, beneficiaries, personal
representatives, successors and assigns, and all others connected with or claiming through you, you agree that this Agreement shall be in complete and final settlement of any and all causes of action, suits, rights and claims, demands, damages and
compensation, whether at law or in equity, whether now known or unknown, suspected or unsuspected, accrued or unaccrued, contingent or otherwise, which you have had in the past, now have, or might now have, against the Company or any of its
Affiliates of any nature whatsoever, including but not limited to those in any way related to, connected with or arising out of your employment, its termination, or your other associations with the Company or any of its Affiliates, or pursuant to
Title VII of the Civil Rights Act, the Americans with Disabilities Act, the Family and Medical Leave Act, the Age Discrimination in Employment Act, as amended by the Older Workers Benefit Protection Act, the Employee Retirement Income Security Act,
the wage and hour, wage payment and fair employment practices laws and statutes (each as amended from time to time) of the state or states in which you have provided services to the Company or any of its Affiliates, and/or any other federal, state,
local or foreign law, regulation or other requirement, including under the laws of the Cayman Islands and the laws of Hong Kong Special Administrative Region of the People’s Republic of China (collectively, the “Claims”), and
you hereby release and forever 

  
 -5- 

 
discharge the Company, its Affiliates and all of their respective past, present and future directors, shareholders, officers, members, managers, general and limited partners, employees, employee
benefit plans, administrators, trustees, agents, representatives, predecessors, successors and assigns, and all others connected with any of them, both individually and in their official capacities (collectively, the “Released
Parties”), from, and you hereby waive, any and all such Claims. For the avoidance of doubt, nothing in this Agreement releases your right to enforce the terms of the Agreement. 

(b) In signing this agreement, you expressly waive and relinquish all rights and benefits provided by Section 1542 of the Civil Code of
the State of California, and do so understanding and acknowledging the significance of such specific waiver of Section 1542, which section states as follows: 

A general release does not extend to claims that the creditor or releasing party does not know or suspect to exist in his or her favor at the
time of executing the release and that, if known by him or her, would have materially affected his or her settlement with the debtor or released party. 

Thus, notwithstanding the provisions of Section 1542, and for the purpose of implementing a full and complete release and discharge of the
Released Parties, you expressly acknowledge that the general release and waiver of claims set forth in this Section 8 is intended to include in its effect, without limitation, all Claims which you do not know or suspect to exist in your favor
at the time you sign it, and that this Agreement contemplates the extinguishment of any and all such Claims. 
 (c) Nothing contained in this
Agreement shall be construed to prohibit you from filing a charge with or participating in any investigation or proceeding conducted by the federal Equal Employment Opportunity Commission or a comparable state or local agency, provided, however,
that you hereby agree to waive your right to recover monetary damages or other individual relief in any such charge, investigation or proceeding or any related complaint or lawsuit filed by you or by anyone else on your behalf. Nothing in this
Agreement limits, restricts or in any other way affects your communicating with any governmental agency or entity, or communicating with any official or staff person of a governmental agency or entity, concerning matters relevant to such
governmental agency or entity. 
 (d) This Agreement, including the general release and waiver of claims set forth in Sections 8(a) and 8(b),
creates legally binding obligations and the Company and its Affiliates therefore advise you to consult an attorney before signing this Agreement. In signing this Agreement, you give the Company and its Affiliates assurance that you have signed it
voluntarily and with a full understanding of its terms; that you have had sufficient opportunity of not less than twenty-one (21) days, before signing this Agreement, to consider its terms and to consult
with an attorney (and that you have in fact consulted with an attorney regarding the terms of this Agreement), and to consult with any other of those persons to whom reference is made in Section 6(b) above, if you wished to do so; and that you
have not relied on any promises or representations, express or implied, that are not set forth expressly in this Agreement. 

  
 -6- 

 9. Miscellaneous. 

(a) This Agreement constitutes the entire agreement between you and the Company and supersedes all prior and contemporaneous communications,
agreements and understandings, whether written or oral, with respect to your employment, its termination and all related matters, including but not limited to the Employment Agreement, and excluding only the Continuing Obligations, all of which
shall remain in full force and effect in accordance with their terms. 
 (b) This Agreement may not be modified or amended, and no breach
shall be deemed to be waived, unless agreed to in writing by you and the Board or its expressly authorized designee. The captions and headings in this Agreement are for convenience only, and in no way define or describe the scope or content of any
provision of this Agreement. 
 (c) The obligation of the Company to make payments or provide benefits to you or on your behalf under this
Agreement, and your right to retain the same, is expressly conditioned upon your continued full performance of your obligations under this Agreement (including the Continuing Obligations).

 Exhibit 10.32 

Execution Version 

AMENDED AND RESTATED EXECUTIVE EMPLOYMENT AGREEMENT 

THIS AMENDED AND RESTATED EXECUTIVE EMPLOYMENT AGREEMENT (this “Agreement”) is made and entered into as of September 14, 2021
by and among (i) LianBio, an exempted company organized under the laws of the Cayman Islands (“LianBio”), (ii) LianBio, LLC, a limited liability company organized under the laws of the State of Delaware, the United States of
America (the “Company”), and (iii) Debra Yu, an American citizen whose passport number is                  (the “Employee”). 

WHEREAS, LianBio, the parent of the Company, and the Employee entered into an employment agreement on September 18, 2019 (the
“2019 Agreement”) under which LianBio employs the Employee as its President and the Chief Business Officer subject to the terms and conditions of the 2019 Agreement. 

WHEREAS, LianBio desires to promote the Employee to the role of President and Chief Strategy Officer subject to the terms and conditions of
the Agreement. 
 WHEREAS, LianBio and the Employee each desire that the Company be substituted for LianBio under the 2019 Agreement, and
the Company and the Employee agree to amend and restate the 2019 Agreement by entering into this Agreement as hereinafter set forth. 
 NOW,
THEREFORE, in consideration of the mutual covenants and obligations hereinafter set forth, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows: 

1.    Assignment. LianBio irrevocably assigns to the Company all rights and obligations of LianBio under the 2019
Agreement (the “Assignment”). The Company and the Employee hereby irrevocably accepts the Assignment, as if the Company had at all times been a party to the 2019 Agreement in place of LianBio. 

2.    Employment. The Company hereby agrees to employ the Employee and the Employee hereby accepts employment with
the Company upon the terms and conditions hereinafter set forth. 
 3.    Term. Subject to the provisions of
Sections 9, 10, 11 and 12 hereof, the initial term of the Employee’s employment with the Company, which commenced as of October 1, 2019, shall end on January 1, 2024 (the “Initial Term”).
Unless earlier terminated by the Company or the Employee in accordance with the terms and conditions set forth herein, the Employee’s employment by the Company hereunder shall automatically be renewed following the Initial Term for subsequent
one (1) year periods (each, a “Renewal Term”) unless either party gives a notice of non-renewal to the other party not later than ninety (90) days prior to the expiration of such
Initial Term or Renewal Term, as applicable (such notice, “Non-Renewal Notice”). Notwithstanding the foregoing, in the event of a Change in Control (as defined below) occurring during the
Employment Period (as defined below), the then current Initial Term or Renewal Term, as applicable, will be converted to an indefinite term, meaning that (a) the Employee or the Company may terminate the Employee’s employment at any time
pursuant to Sections 9, 10, 11 or 12 hereof, and (b) the terms hereof with respect to the renewal and/or non-renewal of the term of the Employee’s employment shall cease
to apply. The term “Employment Period” shall mean the Initial Term and, if applicable, the Renewal Term or any shorter period resulting from any termination of service under Sections 9, 10, 11 and 12
hereof. 
 4.    Location. The Employee will be initially based in the State of New Jersey, the US. For the
avoidance of doubt, the Employee may need to travel to other locations as required by the Company or the board of directors of LianBio (the “Board”) from time to time, with the understanding that the Employee is required to perform
certain of her duties at the offices of the 

 
affiliates of the Company in Shanghai, the People’s Republic of China (the “PRC”), Hong Kong and Singapore and shall spend significant time in such places every year as may
be reasonably determined by the Board. The Employee hereby agrees to sign such other agreements or documents as may reasonably be requested by the Company (or its relevant affiliate(s)) in order to obtain the relevant work permit and residence
permits issued by the PRC government and other regulators for the Employee to legally work and reside in Shanghai. For the avoidance of doubt, the Employee agrees that the requirements set forth in this Section 4 are
material terms of this Agreement. 
 5.    Duties and Responsibilities. The Employee will serve as the President
and the Chief Strategy Officer (the “CSO”) of the Company. The Employee will perform such duties and services as are customary for the positions of President and CSO in similarly situated enterprises in the biopharmaceutical
industry and such other duties as may be reasonably assigned to her from time to time by the Chief Executive Officer of the Company (the “CEO”). In furtherance of the foregoing, the Employee hereby agrees to perform faithfully such
duties and responsibilities and the other reasonable duties and responsibilities assigned to her from time to time by the CEO. 

6.    Time to be Devoted to Service. Except for reasonable vacations, absences due to temporary illness, and
activities that may be mutually agreed to by the parties, the Employee shall devote her entire time, attention and energies during normal business hours and such evenings and weekends as may be reasonably required for the discharge of her duties to
the business of the Company while the Employee is employed by the Company during the Employment Period. During the Employment Period, the Employee will not be engaged in any other business activity that, in the reasonable judgment of the Board,
conflicts with the duties of the Employee hereunder (including without limitation, any activities that present a conflict of interest) without the prior written consent of the Company. The Employee and the Company agree that, subject to receiving
prior written consent from the Board, the Employee may serve as a director of other corporations and/or non-profit organizations, provided that such directorships do not, individually or in the
aggregate, conflict with the duties of the Employee hereunder (including without limitation, any directorships that present a conflict of interest). 

7.    Conflict of Interest. The Employee has reviewed with the Board (i) the present directorships and other
positions or roles held by the Employee or her associate(s) in all such business organizations or arrangements that may be directly competitive or directly in conflict with the Company and (ii) ownership interests (legal or beneficial, direct
or indirect) in another company held by the Employee or her associate(s) comprising more than two percent (2%) of such company, schedules of which are listed on Schedule 1 hereto. During the Employment Period, the Employee agrees to review
with the Board any potential directorships, ownership (legal and beneficial, direct and indirect) interests and other positions or roles with business organizations or arrangements that may be directly competitive or directly in conflict with the
Company. Except as set forth in Schedule 1 hereto, the Employee or her associate(s) is precluded from owning an interest (legal and beneficial, direct and indirect) in another company comprising more than two percent (2%) of such company or
serving as an employee, director, consultant, advisor or member of such other company that may be directly competitive or directly in conflict with the Company until such interest is presented to the Board and the Board consents to such interest or
employment. 
 8.    Compensation; Benefits; Reimbursement. 

8.1    Base Salary. During the Employment Period, the Employee shall receive as compensation an initial annual base
salary of US$500,000 (the “Base Salary”), less any payroll taxes or withholdings legally required or properly requested by the Employee. This Base Salary all other compensation and reimbursement under the Agreement will be payable
in such installments as are applicable to employees of the Company at substantially the same service level as the Employee. The Board will review the Base Salary on an annual basis and may, in its sole discretion, increase the amount to adjust for
inflations and/or market changes. 

  
 2 

 8.2    Equity Awards. During the Employment Period, the Employee
will be eligible to receive stock-based awards (including stock option awards), including in connection with the initial public offering of LianBio’s ordinary shares, under LianBio’s 2019 Equity Incentive Plan, or such other long-term
incentive plan as may be adopted by LianBio from time to time, at a level commensurate with her position and responsibilities as specified above and subject to such terms as shall be established by the Board, or a committee thereof, from time to
time in its or their discretion. 
 8.3    Bonus. At the conclusion of each calendar year during the Employment
Period, the Employee may be entitled to receive a performance-based annual bonus with a target equal to one hundred percent (100%) of the Base Salary (the “Performance Bonus”), the actual amount of which shall be determined by the
Board in its sole and exclusive discretion based on the Board’s evaluation of the Employee’s performance and other pre-agreed parameters reflecting the Company’s business plan. The Employee is
eligible to receive an additional annual cash bonus in excess of the Performance Bonus, the amount of which shall be determined by the Board, in its sole and exclusive discretion. 

8.4    Fringe Benefits. During the Employment Period, the Employee will be entitled to the fringe benefits that are
made available to officers of the Company and such other benefits as are determined by the Board or a committee thereof, in its sole and exclusive discretion. 

8.5    Reimbursements. During the Employment Period, the Employee will be reimbursed, in accordance with the
Company’s expense reimbursement policy as in effect from time to time, for all reasonable traveling expenses and other disbursements incurred by her for or on behalf of the Company in the performance of her duties hereunder upon presentation by
the Employee of appropriate vouchers. 
 8.6    Deductions. Recognizing that the Employee is an employee for all
purposes, the Company or a subsidiary of the Company shall deduct from any compensation payable to the Employee the sums which the Company or such subsidiary is required by law to deduct, including, but not limited to, government state withholding
taxes, social security taxes and state disability insurance and mandatory provident funds, and the Company or such subsidiary shall pay any amounts so deducted to the applicable governmental entities and agents entitled to receive such payments.

 9.    Involuntary Termination. 

9.1    Disability. If the Employee dies, then the Employee’s employment by the Company hereunder shall
automatically terminate on the date of the Employee’s death. If the Employee is incapacitated or disabled by accident, sickness or otherwise so as to render her mentally or physically incapable of performing the services required to be
performed by her under this Agreement, either with or without reasonable accommodation, for a period of ninety (90) consecutive days or longer, or for ninety (90) days during any six (6) month period (such condition being herein
referred to as “Disability”), the Company, at its option, may terminate the Employee’s employment under this Agreement immediately upon giving her notice to that effect. In the case of a Disability, until the Company shall have
terminated the Employee’s service in accordance with the foregoing, the Employee will be entitled to receive compensation, at the rate and in the manner provided in Section 8, notwithstanding any such physical or
mental disability. Termination pursuant to this Section 9 is hereinafter referred to as an “Involuntary Termination”. 

9.2    Substitution. The Board may designate another employee to act in the Employee’s place during any period
of Disability suffered by the Employee during the Employment Period. Notwithstanding any such designation, the Employee shall continue to receive the Employee’s Base Salary and benefits in accordance with Section 8 of
this Agreement until the Employee becomes eligible for disability income under the Company’s disability income insurance (if any) or until the termination of the Employee’s employment, whichever shall first occur. 

  
 3 

 9.3    Disability Income Payments. While receiving disability
income payments under the Company’s disability income insurance (if any), the Employee shall not be entitled to receive any Base Salary under Section 8.1, but shall continue to participate in all other compensation and
benefits in accordance with Section 8.4 until the date of the Employee’s termination of employment. 

9.4    Verification of Disability. If any question shall arise as to whether during any period the Employee is
disabled through any illness, injury, accident or condition of either a physical or psychological nature so as to be unable to perform substantially all of the Employee’s duties and responsibilities hereunder, the Employee may, and at the
request of the Company shall, submit to a medical examination by a physician selected by the Company to whom the Employee or the Employee’s guardian has no reasonable objection to determine whether the Employee is so disabled and such
determination shall for the purposes of this Agreement be conclusive of the issue. If such question shall arise and the Employee shall fail to submit to such medical examination, the Company’s determination of the issue shall be binding on the
Employee. 
 10.    Termination for Cause. The Company, on recommendation from the Board, may terminate the
employment of the Employee hereunder at any time during the Employment Period for Cause (such termination being hereinafter referred to as a “Termination for Cause”) by giving the Employee notice of such termination, upon the giving
of which such termination shall take effect immediately. For the purposes of this Agreement, “Cause” means any one of the following grounds: (i) repeated drunkenness or use of illegal drugs which adversely interferes with the
performance of the Employee’s obligations and duties in the Company; (ii) the Employee’s conviction of a felony, or any crime involving fraud or misrepresentation or violation of applicable securities laws; (iii) gross
mismanagement by the Employee of the business and affairs of the Company or any subsidiary of the Company which is reasonably likely to result in a material loss to the Company or any subsidiary of the Company; (iv) material violation of any

 11.    Termination without Cause.
The Company, on recommendation from the Board, may terminate the employment of the Employee hereunder at any time during the Employment Period without Cause (such termination being hereinafter called a “Termination without Cause”)
by giving the Employee sixty (60) days’ prior written notice of such termination or pay in lieu of such notice (or any portion thereof). In the event of termination of the Employee’s employment in accordance with this
Section 11, the Company may elect to waive the period of notice, or any portion thereof, and, if the Company so elects, the Company will pay the Employee the Base Salary for the period so waived. 

12.    Termination by the Employee. 

12.1    Without Good Reason. Any termination of the employment of the Employee hereunder other than as a result of
an Involuntary Termination, a Termination for Cause, a Termination without Cause, a Termination for Good Reason (as defined below) or a Non-Renewal Termination (as defined below) will be referred to
hereinafter as a “Voluntary Termination”. A Voluntary Termination will be deemed to be effective thirty (30) days after written notice hereof. 

12.2    With Good Reason. The Employee may terminate the services of such Employee hereunder at any time for Good

Employee terminates her employment, if at all, not later than thirty (30) days after the expiration of such cure period (such termination being hereinafter referred to as a
“Termination for Good Reason”). For purposes of this Agreement, the term “Good Reason” shall mean (a) any material diminution of the Employee’s duties or responsibilities hereunder (except in each case in
connection with the Termination for Cause or pursuant to Section 9.2) or the assignment to the Employee of duties or responsibilities that are materially inconsistent with the Employee’s then current position; or

plus any additional compensation as may be expressly required under applicable law; 

  

	 	(iii)	 reimbursement for any expenses for which the Employee shall not have theretofore been reimbursed as provided in
Section 8.5; and 

  

	 	(iv)	 any other benefits as required by applicable law.

	 	(iv)	 any other benefits as required by applicable law. 

13.5    Change in Control Termination. Upon the termination of the Employee’s employment hereunder pursuant to

	 	(iv)	 reimbursement for any expenses for which the Employee shall not have theretofore been reimbursed as provided in
Section 8.5; and 

  

	 	(v)	 any other benefits as required by applicable law. 

For purposes of this Agreement, “Change in Control” means the occurrence of any of the following: 

  
 6 

	 	(i)	 any one person, or more than one person acting as a group (“Person”), acquires ownership of
the stock of LianBio that, together with the stock held by such Person, constitutes more than 50% of the total voting power of the stock of LianBio, except that any change in the ownership of the stock of LianBio as a result of a private financing
of LianBio that is approved by the Board will not be considered a Change in Control; or 

  

	 	(ii)	 the sale of all or substantially all assets of LianBio. 

For purposes of this definition, Persons will be considered to be acting as a group if they are owners of a corporation that enters into a merger,
consolidation, purchase or acquisition of stock, or similar business transaction with LianBio. Further and for the avoidance of doubt, a transaction will not constitute a Change in Control if: (i) its sole purpose is to re-domicile LianBio in a jurisdiction other than its original jurisdiction of incorporation, or (ii) its sole purpose is to create a holding company that will be owned in substantially the same proportions by
the persons who held LianBio’s securities immediately before such transaction. With regard to any payment considered to be nonqualified deferred compensation under Section 409A (as defined below), to the extent applicable, that is payable
upon a Change in Control, to avoid the imposition of an additional tax, interest or penalty under Section 409A, no amount will be payable unless such change in control constitutes a “change in control event” within the meaning of Section 1.409A-3(i)(5) of the Treasury Regulations. 
 13.6    Release.
The parties acknowledge and agree that damages which will result to the Employee for Termination without Cause by the Company or other breach of this Agreement by the Company shall be extremely difficult or impossible to establish or prove, and
agree that the Severance Payment shall constitute liquidated damages for any breach of this Agreement by the Company through the date of termination. The Employee agrees that, except for such other payments and benefits to which the Employee may be
entitled as expressly provided by the terms of this Agreement or any applicable benefit plan, such liquidated damages shall be in lieu of all other claims that the Employee may make by reason of termination of her employment or any such breach of
this Agreement and that, as a condition to receiving the Severance Payment, the Employee will execute a release of claims in a form reasonably satisfactory to the Company. 

14.    Indemnification of Employee. 

14.1    Indemnification. In the event that (a) the Employee was or is a party or is threatened to be made a
party to any Proceeding (as defined below) by reason of the Employee’s Corporate Status (as defined below) or (b) the Employee was or is a party or is threatened to be made a party to any Proceeding by or in the right of the Company to
procure a judgment in its favor by reason of the Employee’s Corporate Status, the Employee shall be indemnified by the Company against all Expenses (as defined below) and Liabilities (as defined below) incurred or paid by the Employee in
connection with such Proceeding (referred to herein as “Indemnifiable Amounts”). For purposes hereof, the terms (i) “Proceeding” means any threatened, pending or completed claim, action, suit, arbitration, alternate
dispute resolution process, investigation, administrative hearing, appeal, or any other proceeding, whether civil, criminal, administrative, arbitrative or investigative, whether formal or informal, (ii) “Corporate Status” means the
status of the Employee as an employee and/or director of the Company, as applicable, (iii) “Expenses” means all fees, costs and expenses incurred in connection with any Proceeding, including, without limitation, reasonable
attorneys’ fees, disbursements and retainers, fees and disbursements of expert witnesses, private investigators and professional advisors (including, without limitation, accountants and investment bankers), court costs, transcript costs, fees
of experts, travel expenses, duplicating, printing and binding costs, telephone and fax transmission charges, postage, delivery services, secretarial services and other disbursements and expenses and (iv) “Liabilities” means
judgments, damages, liabilities, losses, penalties, excise taxes, and fines. 

  
 7 

 14.2    Advancement of Expenses. The Company agrees that the
Company shall pay to the Employee all Indemnifiable Amounts incurred by the Employee in connection with any Proceeding, including a Proceeding by the right of the Company, in advance of the final disposition of such Proceeding, as the same are
incurred, provided that the Employee provides the Company with a written undertaking to repay the amount of Indemnifiable Amounts if it is finally determined by a court of competent jurisdiction that the Employee is not entitled under this Agreement
to indemnification with respect to such Indemnifiable Amounts. 
 14.3    Limitation on Indemnification. The
Employee shall not be entitled to any indemnification under this Section 14 if the Employee knowingly violated any duty, responsibility or obligation of the Employee imposed under this Agreement, the Compliance Agreement or
any Company policy. 
 14.4    Change in Law. To the extent that a change in applicable law (whether by statute
or judicial decision) shall permit broader indemnification or advancement of expenses than is provided under this Agreement, the Employee shall be entitled to such broader indemnification and advancements, and this Agreement shall be deemed to be
amended to such extent. 
 15.    Compliance Agreement. The Employee agrees to continue to be bound by the
Agreement Regarding Confidentiality, Trade Secrets, Intellectual Property and Competitive Activities executed by the Company and the Employee on September 19, 2019 (the “Compliance Agreement”, attached hereto as Exhibit
A), the terms and conditions of which are specifically incorporated herein by reference. Notwithstanding the foregoing, the parties hereto hereby agree that Section 3(a)(2) of the Compliance Agreement shall not apply to the Employee
following the date of termination if the Employee’s employment is terminated as a result of (a) a Non-Renewal by the Company or (b) a Change in Control Termination. The obligation of the Company
to make payments to or on behalf of the Employee under Section 13.2(ii), Section 13.3(ii), Section 13.4(ii) or Section 13.5(ii) above is
expressly conditioned upon the Employee’s continued performance of the Employee’s obligations under the Compliance Agreement. 

16.    Compliance with Anti-Bribery, Anti-Corruption, Etc. The Employee hereby agrees to attend any and all
compliance trainings required by the Company and to comply with all applicable laws relating to anti-bribery, anti-corruption, anti-money laundering, record keeping and internal control laws, including but not limited to the People’s Republic
of China Criminal Law, the People’s Republic of China Anti-Unfair Competition Law, the United States Foreign Corrupt Practices Act and the United Kingdom Bribery Act (together, “ABAC Policies”), with respect to all activities
undertaken on behalf or in connection with the business of the Company, its affiliates or its subsidiaries. The Employee further agrees that the Employee will not, directly or indirectly, offer, authorize, promise, condone or participate in:
(a) the making of any gift or payment of anything of value to any public official by any person or entity to obtain any improper advantage, affect or influence any act or decision of any such public official, or assist the Company, its
affiliates or its subsidiaries in obtaining or retaining business for, or with, or directing business to, any person or entity, (b) the taking of any action by any person or entity which (i) would violate ABAC Policies, if taken by an
entity subject to ABAC Policies, or (ii) could reasonably be expected to constitute a violation of any applicable law, (c) the making of any false or fictitious entries in the books or records of the Company, its affiliates or its
subsidiaries by any person or entity, or (d) the using of any assets of the Company, its affiliates or its subsidiaries for the establishment of any unlawful or unrecorded fund of monies or other assets, or the making of any unlawful or
undisclosed payment.

restrictive than permitted by the laws of any jurisdiction whose law may be deemed to govern the review and interpretation of this Agreement, the terms of such restriction, for the purpose only of the operation of such restriction in such
jurisdiction, 

  
 8 

 
will be the maximum restriction allowed by the laws of such jurisdiction and such restriction will be deemed to have been revised accordingly herein. A court having jurisdiction over an action
arising out of or seeking enforcement of any restriction contained in this Agreement may modify the terms of such restriction in accordance with this Section 17. 

18.    Notices. All notices and other communications given or made pursuant to this Agreement shall be in writing

27 and 30 of this Agreement shall survive the termination of this Agreement. 
 20.    Binding

21.    Governing Law. This Agreement shall be governed by and construed under the laws of the State of New Jersey,

22.    Waiver of Breach. The waiver by either party of a breach of any provision of this Agreement by the other
party must be in writing and will not operate or be construed as a waiver of any subsequent breach by such other party. 

23.    Entire Agreement; Amendments. This Agreement contains the entire agreement between the parties with respect
to the subject matter hereof and supersedes all prior agreements or understanding among the parties with respect thereto. This Agreement may be amended only by an agreement in writing signed by each of the parties hereto. 

24.    Headings. The Section headings contained in this Agreement are for reference purposes only and will not
affect in any way the meaning or interpretation of this Agreement. 
 25.    Severability. Subject to the
provisions of Section 17 above, any provision of this Agreement that is prohibited or unenforceable in any jurisdiction will, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability

26.    Assignment. This Agreement is personal in its nature and the parties hereto shall not, without the consent
of the other party hereto, assign or transfer this Agreement or any rights or obligations hereunder, provided, however, that the rights and obligations of the Company hereunder shall be assignable and delegable in connection with any subsequent

 9

29.    Counterparts. The parties may execute this Agreement in any number of counterparts and, as so delivered, the
counterparts shall together constitute one and the same document. The parties agree that each such counterpart is an original and shall be binding upon all of the parties, even though all of the parties are not signatories to the same counterpart.

 30.    Dispute Resolution. 

30.1    Any dispute, controversy or claim (each, a “Dispute”) arising out of or relating to this
Agreement, or the interpretation, breach, termination, validity or invalidity thereof, shall be referred to and conclusively determined by arbitration upon the demand of any party to the dispute with notice (the “Arbitration
Notice”) to the other party or parties. The only claims not covered by this agreement to arbitrate are claims for benefits under U.S. workers’ compensation or unemployment insurance statutes and other claims that cannot be arbitrated
as a matter of law. Any Dispute must be brought to arbitration within the statute of limitations for bringing such Dispute in court or before the appropriate administrative agency, as applicable. 

30.2    The Dispute shall be settled by arbitration in New Jersey administered by JAMS in accordance with its Employment
Arbitration Rules & Procedures. In the event that JAMS fails or refuses to conduct the arbitration in New Jersey, then the Dispute shall be resolved by binding arbitration before JAMS in New York. 

30.3    The disputing parties may jointly select one (1) arbitrator, or agree that JAMS shall select the arbitrator.
In the absence of such agreement, there shall be three (3) arbitrators, the claimant to the Dispute, or in the case of multiple claimants, all such claimants acting collectively (the “Claimant”) shall select one
(1) arbitrator and the respondent to the Dispute, or in the case of more than one respondent, the respondents acting collectively (the “Respondent”) shall select one (1) arbitrator. All selections shall be made within
thirty (30) days after the selecting party gives or receives the demand for arbitration. Such arbitrators shall be freely selected, and neither the Claimant nor the Respondent shall be limited in their selection to any prescribed list. The
Chairman of JAMS shall select the third arbitrator who will act as chairman of the arbitration board. If any arbitrator to be appointed by a party has not been appointed and consented to participate within thirty (30) days after the selection
of the first arbitrator, the relevant appointment shall be made by the Chairman of JAMS. 
 30.4    The arbitral
proceedings shall be conducted in English. To the extent that the Employment Arbitration Rules & Procedures of JAMS are in conflict with the provisions of this Section, including the provisions concerning the appointment of the arbitrators,
the provisions of this Section shall prevail. 
 30.5    Each party to the arbitration shall cooperate with each other
party to the arbitration in making full disclosure of and providing complete access to all information and documents requested by such other party in connection with such arbitral proceedings, subject only to any confidentiality obligations binding
on such party. If the arbitration is conducted in New York, the arbitrator shall permit adequate discovery, shall issue a written award, and is authorized to award any type of relief recoverable in court. 

30.6    The decision of the arbitral tribunal shall be final and binding upon the parties thereto, and the prevailing
party may apply to a court of competent jurisdiction for enforcement thereof. 

  
 10 

 30.7    The arbitral tribunal shall decide any Dispute submitted by the
parties to the arbitration strictly in accordance with the substantive laws of the State of New Jersey. 
 30.8    Any
party to the Dispute shall be entitled, without posting any bond, to seek preliminary injunctive relief, temporary restraining order or other temporary relief (if applicable), from any court of competent jurisdiction pending the constitution of the
arbitral tribunal. 
 30.9    During the course of the arbitral tribunal’s adjudication of the Dispute, this
Agreement shall continue to be performed except with respect to the part in dispute and under adjudication. 

30.10    (i) The Employee acknowledges and agrees that no claims will be arbitrated on a class action or collective action
basis, (ii) the arbitration costs incurred by the Employee shall not exceed the cost of filing a complaint in a court of law or equity, and (iii) the parties expressly waive all rights to a jury trial in court on all statutory or other
claims. 
 31.    Timing of Payments and Section 409A. 

31.1    Notwithstanding anything to the contrary in this Agreement, if at the time the Employee’s employment
terminates, the Employee is a “specified employee,” as defined below, any and all amounts payable under this Agreement on account of such separation from service that would (but for this provision) be payable within six (6) months
following the date of termination, shall instead be paid on the next business day following the expiration of such six (6)-month period or, if earlier, upon the Employee’s death; except (A) to the extent of amounts that do not constitute a
deferral of compensation within the meaning of Treasury regulation Section 1.409A-1(b) (including without limitation by reason of the safe harbor set forth in
Section 1.409A-1(b)(9)(iii), as determined by the Company in its reasonable good faith discretion); (B) benefits which qualify as excepted welfare benefits pursuant to Treasury regulation Section 1.409A-1(a)(5); or (C) other amounts or benefits that are not subject to the requirements of Section 409A of the Internal Revenue Code of 1986, as amended
(“Section 409A”). 
 31.2    For purposes of this Agreement, to the extent required
to comply with Section 409A, all references to “termination of employment” and correlative phrases shall be construed to require a “separation from service” (as defined in
Section 1.409A-1(h) of the Treasury regulations after giving effect to the presumptions contained therein), and the term “specified employee” means an individual determined by the Company to be
a specified employee under Treasury regulation Section 1.409A-1(i) 

31.3    Any reimbursement for expenses that would constitute nonqualified deferred compensation subject to
Section 409A shall be subject to the following additional rules: (i) no reimbursement of any such expense shall affect the Employee’s right to reimbursement of any such expense in any other taxable year; (ii) reimbursement of the
expense shall be made, if at all, promptly, but not later than the end of the calendar year following the calendar year in which the expense was incurred; and (iii) the right to reimbursement shall not be subject to liquidation or exchange for
any other benefit. 
 31.4    In no event shall the Company have any liability relating to the failure or alleged
failure of any payment or benefit under this Agreement to comply with, or be exempt from, the requirements of Section 409A.
