All statements other than statements of historical facts contained in this Quarterly Report are forward-looking statements. In some cases, you can identify forward-looking statements by terms such as "may," "can," "will," "would," "should," "expect," "plan," "anticipate," "could," "intend," "target," "project," "contemplate," "believe," "estimate," "predict," "potential," or "continue" or the negative of these terms or other similar expressions, although not all forward-looking statements contain these words. All statements other than statements of historical facts contained in this Quarterly Report, including without limitation statements regarding:

● the timing, progress and results of preclinical studies and clinical studies for our product candidates, including our product development plans and strategies;

● other risks and uncertainties, including those described under Part II. Item 1A. "Risk Factors" in this Quarterly Report.

[**Table of Contents**](#TOC)

The forward-looking statements in this Quarterly Report are only predictions and are based largely on our current expectations and projections about future events and trends that we believe may affect our financial condition, results of operations, business strategy, short-term and long-term business operations and objectives, and financial needs. These forward-looking statements speak only as of the date of this Quarterly Report and are subject to a number of known and unknown risks, uncertainties, and assumptions, including those described under Part I. Item 2 "Management's Discussion and Analysis of Financial Condition and Results of Operations" and Part II. Item 1A. "Risk Factors" elsewhere in this Quarterly Report. Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for our management to predict all risks, 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 may make. In light of these risks, uncertainties, and assumptions, the future events and trends discussed in this Quarterly Report may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements.

Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified, you should not rely upon these forward-looking statements as predictions of future events. The events and circumstances reflected in the forward-looking statements may not be achieved or occur. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, performance, or achievements. The forward-looking statements made in this Quarterly Report relate only to events or information as of the date on which the statements are made in this Quarterly Report. Except as required by applicable law, we do not plan to publicly update or revise any forward-looking statements contained herein, whether as a result of any new information, future events, changed circumstances or otherwise. We intend the forward-looking statements contained in this Quarterly Report to be covered by the safe harbor provisions for forward-looking statements contained in Section 27A of the Securities Act of 1933, as amended (the "Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act").

#### SUMMARY RISK FACTORS
Our business is subject to numerous risks and uncertainties, including those described in Part II. Item 1A. "Risk Factors" in this Quarterly Report. You should carefully consider these risks and uncertainties when investing in our securities. The principal risks and uncertainties affecting our business include the following:

◾ We have a limited operating history, have incurred significant operating losses since our inception and expect to incur significant losses for the foreseeable future.

---

| | |
|:---|:---|
| ◾ | We will require substantial additional capital to finance our operations, which may not be available on acceptable terms, or at all. Failure to obtain this necessary capital when needed may force us to delay, limit or terminate certain of our product development programs, commercialization efforts or other operations. |

---

◾ Our approach to the discovery of product candidates based on our technology platform is unproven, and we do not know whether we will be able to develop any products of commercial value.

---

| | |
|:---|:---|
| ◾ | We are early in our development efforts and only have three product candidates, aleniglipron, ANPA-0073 and LTSE-2578, in early clinical development. All of our other development programs are in the preclinical or discovery stage. If we are unable to advance our product candidates in clinical development, obtain regulatory approval and ultimately commercialize our product candidates, or experience significant delays in doing so, our business will be materially harmed. |

---

---

| | |
|:---|:---|
| ◾ | Clinical and preclinical drug development involves a lengthy and expensive process with uncertain timelines and outcomes. The results of prior clinical studies and preclinical studies are not necessarily predictive of future results, and may not be favorable, or receive regulatory approval on a timely basis, if at all. |

---

[**Table of Contents**](#TOC)

◾ Any difficulties or delays in the commencement or completion, or termination or suspension, of our planned clinical studies could result in increased costs to us, delay or limit our ability to generate revenue and adversely affect our commercial prospects.

---

| | |
|:---|:---|
| ◾ | Serious adverse events, undesirable side effects or other unexpected properties of our product candidates may be identified during development or after approval, which could lead to the discontinuation of our clinical development programs, refusal by regulatory authorities to approve our product candidates or, if discovered following marketing approval, revocation of marketing authorizations or limitations on the use of our product candidates, any of which would limit the commercial potential of such product candidate. |

---

◾ As an organization, we have never conducted later-stage clinical studies or submitted a New Drug Application ("NDA"), and may be unable to do so for any of our product candidates.

---

| | |
|:---|:---|
| ◾ | The marketing approval processes of the U.S. Food and Drug Administration ("FDA") and applicable foreign authorities are lengthy, time consuming, expensive and inherently unpredictable, and if we are ultimately unable to obtain marketing approval for our product candidates, our business will be substantially harmed. |

---

---

| | |
|:---|:---|
| ◾ | We have conducted, or plan to conduct, our initial clinical studies for aleniglipron, ANPA-0073, LTSE-2578 and our other product candidates outside of the United States. However, the FDA and other foreign equivalents may not accept data from such studies, in which case our development plans will be delayed, which could materially harm our business. |

---

◾ International trade policies, including tariffs, sanctions and trade barriers may adversely affect our business, financial condition, results of operations and prospects.

---

| | |
|:---|:---|
| ◾ | Disruptions to the operations of the FDA, the SEC, other U.S. governmental agencies or comparable foreign regulatory authorities caused by funding shortages, leadership changes, staffing cuts or other staffing shortages, along with uncertainty regarding the potential for new initiatives, laws, regulations, policies and guidance affecting our product candidates or other aspects of our business, could materially and adversely affect our business. |

---

---

| | |
|:---|:---|
| ◾ | We rely on third parties for the manufacture of our product candidates for preclinical and clinical development and expect to continue to do so for the foreseeable future. This reliance on third parties increases the risk that we will not have sufficient quantities of our product candidates or products or such quantities at an acceptable cost, which could delay, prevent or impair our development or commercialization efforts. |

---

◾ Our current and anticipated future dependence upon others for the manufacture of our product candidates or drugs may adversely affect our future profit margins and our ability to commercialize any product candidates that receive marketing approval on a timely and competitive basis.

---

| | |
|:---|:---|
| ◾ | We rely on third parties to conduct, supervise and monitor our discovery research, preclinical studies and clinical studies. We have experienced delays due to actions of third parties in the past and if in the future third parties do not satisfactorily carry out their contractual duties or fail to meet expected deadlines, our development programs may be delayed or subject to increased costs, each of which may have an adverse effect on our business and prospects. |

---

---

| | |
|:---|:---|
| ◾ | We have entered into, and may in the future enter into, collaboration agreements and strategic alliances to maximize the potential of our structure-based drug discovery platform and product candidates, and we may not realize the anticipated benefits of such collaborations or alliances. We expect to continue to form collaborations in the future with respect to our product candidates, but may be unable to do so or to realize the potential benefits of such transactions, which may cause us to alter or delay our development and commercialization plans. |

---

[**Table of Contents**](#TOC)

◾ Our existing discovery collaborations with Schrödinger (as defined below) are important to our business. If we are unable to maintain these collaborations, or if these collaborations are not successful, our business could be adversely affected.

◾ We face substantial competition, which may result in others discovering, developing or commercializing products before or more successfully than us.

---

| | |
|:---|:---|
| ◾ | We currently have no marketing and sales organization and have no experience as a company in commercializing products, and we may invest significant resources to develop these capabilities. If we are unable to establish marketing and sales capabilities or enter into agreements with third parties to market and sell our products, we may not be able to generate product revenue. |

---

---

| | |
|:---|:---|
| ◾ | We conduct certain research and development operations through our Australian wholly-owned subsidiaries. If we lose our ability to operate in Australia, or if any of our subsidiaries are unable to receive the research and development tax credit allowed by Australian regulations, or are required to refund any research and development tax credit previously received or reserve for such credit in our financial statements, our business and results of operations could suffer. |

---

◾ Changes in the political and economic policies or in relations between China and the United States may affect our business, financial condition, results of operations and the market price of our American Depositary Shares ("ADSs").

---

| | |
|:---|:---|
| ◾ | If we are unable to obtain and maintain sufficient intellectual property protection for our platform technologies and product candidates, or if the scope of the intellectual property protection is not sufficiently broad, our competitors could develop and commercialize products similar or identical to ours, and our ability to successfully commercialize our products may be adversely affected. |

---

---

| | |
|:---|:---|
| ◾ | We may rely on one or more in-licenses from third parties. If we lose these rights, our business may be materially adversely affected, and if disputes arise with one or more licensors, we may be subjected to future litigation as well as the potential loss of or limitations on our ability to develop and commercialize products and technologies covered by these license agreements. |

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1. Organization and Nature of the Business

Structure Therapeutics Inc. (the "Company") is a clinical stage global biopharmaceutical company aiming to develop and deliver novel oral therapeutics to treat a wide range of chronic diseases with unmet medical need. The Company was incorporated in February 2019 in the Cayman Islands, with operating subsidiaries in the United States and China. In June 2022, the Company changed its name from ShouTi Inc. to Structure Therapeutics Inc.

#### Initial Public Offering
On February 7, 2023, the Company closed its initial public offering ("IPO") of American Depositary Shares ("ADSs"). Each ADS represents three ordinary shares. The net proceeds from the IPO were approximately $166.7 million after deducting underwriting discounts and commissions and estimated offering costs.

Upon the closing of the IPO, all outstanding shares of the Company's redeemable convertible preferred shares converted into 67,018,087 ordinary shares. In connection with the completion of its IPO, the Company's memorandum of association was amended and restated to provide for 500,000,000 authorized ordinary shares with a par value of $0.0001 per share and 100,000,000 authorized undesignated shares with a par value of $0.0001 per share, of such class or classes as may be designated by the Company's board of directors in accordance with the Company's amended and restated memorandum and articles of association.

#### Private Placement
On September 29, 2023, the Company entered into a share purchase agreement with certain institutional investors (the "Purchasers"), pursuant to which the Company agreed to sell and issue to the Purchasers an aggregate of 21,617,295 ordinary shares and 2,401,920 newly designated non-voting ordinary shares at a purchase price of $12.49 per share (or the equivalent of $37.47 per ADS), the closing price of its ADS on the Nasdaq Global Market on September 28, 2023 (the "Private Placement"). Each holder of non-voting ordinary shares had the right to convert each non-voting ordinary share held by such holder into one ordinary share, subject to certain beneficial ownership limitations. The Private Placement closed on October 3, 2023, and the Company received $281.5 million in net proceeds after deducting placement agent fees and other private placement expenses. As of December 31, 2023, all outstanding non-voting ordinary shares had been converted into ordinary shares.

#### Follow-On Offering
On June 5, 2024, the Company entered into an underwriting agreement with Goldman Sachs & Co. LLC, Morgan Stanley & Co. LLC, Jefferies LLC and Leerink Partners LLC, as representatives of the underwriters named therein (collectively, the "Underwriters"), pursuant to which the Company proposed to issue and sell to the Underwriters an aggregate of 9,066,972 ADSs, each representing three ordinary shares of the Company, and granted the underwriters an option (the "Underwriters' Option") to purchase up to an aggregate of 1,360,045 additional ADSs (the "Follow-On Offering"). The Follow-On Offering closed on June 7, 2024, at which time the Company issued 10,427,017 ADSs, including the issuance of 1,360,045 ADSs in connection with the full exercise of the Underwriters' Option, at a price of $52.50 per ADS. The net proceeds from the Follow-On Offering were approximately $512.7 million after deducting underwriting discounts and commissions and estimated offering costs.

#### At-the-Market Offering
In August 2025, the Company entered into a sales agreement (the "ATM Sales Agreement") with Leerink Partners LLC and Cantor Fitzgerald & Co. (the "ATM Sales Agents"), pursuant to which the Company may,

STRUCTURE THERAPEUTICS INC.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

from time to time, offer and sell ADSs through the ATM Sales Agents in any manner deemed to be an "at-the-market offering," up to an aggregate offering price of $250.0 million (the "ATM Offering"). In September 2025, the Company sold 3,040,000 ADSs under the ATM Sales Agreement, for gross proceeds of approximately $58.5 million. The net proceeds to the Company after deducting sales commissions to the ATM Sales Agents were approximately $57.1 million, and, after further deducting offering expenses, were approximately $55.8 million. As of September 30, 2025, approximately $191.5 million remained available for sale under the ATM Sales Agreement. The shares were sold pursuant to the Company's automatic shelf registration statement on Form S-3, filed with the Securities and Exchange Commission ("SEC") on August 6, 2025 (the "Shelf Registration Statement"), and future shares may be sold pursuant to the Shelf Registration Statement or a subsequent registration statement.

#### Liquidity and Capital Resources
The Company has incurred significant net operating losses and negative cash flows from operations since inception and had an accumulated deficit of $503.3 million as of September 30, 2025. Prior to completion of its IPO, the Company has financed its operations primarily through the private placement of equity securities. In February 2023, the Company completed its IPO for net proceeds of approximately $166.7 million. In October 2023, the Company closed its Private Placement for net proceeds of approximately $281.5 million. In June 2024, the Company closed its Follow-On Offering for net proceeds of approximately $512.7 million. In September 2025, the Company sold 3,040,000 ADSs under the ATM Sales Agreement for net proceeds of approximately $55.8 million.

As of September 30, 2025, the Company had cash, cash equivalents and short-term investments of $799.0 million. Based on its current business plan, the Company believes that its current cash, cash equivalents and short-term investments will be sufficient to fund its projected operations for at least 12 months from the date of the issuance of these condensed consolidated financial statements.

2. Summary of Significant Accounting Policies

#### Basis of Presentation
The condensed consolidated financial statements and related disclosures have been prepared in conformity with accounting principles generally accepted in the United States of America ("GAAP"). The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The functional and reporting currency of the Company and its subsidiaries is the U.S. dollar. The aggregate foreign currency transaction gain (loss) included in determining net loss was not material for the periods presented.

#### Unaudited Interim Financial Information
The condensed consolidated balance sheet as of December 31, 2024 was derived from the Company's audited financial statements, but does not include all disclosures required by GAAP. The accompanying unaudited condensed consolidated financial statements as of September 30, 2025 and for the three and nine months ended September 30, 2025 and 2024, have been prepared by the Company, pursuant to the rules and regulations of the SEC, for interim financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Accordingly, these financial statements should be read in conjunction with the audited financial statements as of and for the year ended December 31, 2024 and notes thereto, included in the Company's Annual Report on Form 10-K for the year ended December 31, 2024 filed with the SEC on February 27, 2025. In the opinion of management, all adjustments, consisting only of normal recurring adjustments necessary for a fair statement of the Company's condensed consolidated financial

STRUCTURE THERAPEUTICS INC.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

position as of September 30, 2025 and condensed consolidated results of operations for the three and nine months ended September 30, 2025 and 2024 and condensed consolidated cash flows for the nine months ended September 30, 2025 and 2024 have been made. The results of operations for the three and nine months ended September 30, 2025 are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2025.

#### Use of Estimates
The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements as well as the reported amounts of expenses during the reporting periods. Such estimates include lease liability, accruals for research and development activities, share-based compensation and certain other accrued liabilities. Actual results could differ from those estimates.

#### Segments
The Company operates and manages its business as one reportable and operating segment, which is the business of research and development of medicines that target chronic diseases with unmet medical need. The Company's Chief Executive Officer, who is the chief operating decision maker ("CODM"), reviews consolidated financial statements and decides how to allocate resources and evaluate segment performance based on net loss reported in the consolidated statements of operations and comprehensive loss. The Company's long-lived assets are primarily in China.

The table below is a summary of the segment net loss, including significant segment expenses (in thousands):

#### Concentration of Credit Risk
The Company is exposed to credit risk from its deposits of cash, cash equivalents and short-term investments in excess of the amount of insurance provided on such deposits. The Company invests its cash, cash equivalents and short-term investments in money market funds, corporate debt securities, U.S. government bonds and U.S. government agency bonds. The Company limits its credit risk associated with cash, cash

[**Table of Contents**](#TOC)

STRUCTURE THERAPEUTICS INC.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

equivalents and short-term investments by investing in investment-grade securities and using banks and institutions it believes are creditworthy. The Company has not experienced any losses on its deposits of cash, cash equivalents and short-term investments to date. The Company has no off-balance sheet concentrations of credit risk, such as foreign currency exchange contracts, option contracts or other hedging arrangements.

#### Risks and Uncertainties
The Company is subject to risks and uncertainties common to companies in the biotechnology industry, including, but not limited to, development by competitors of new technological innovations, protection of proprietary technology, dependence on key personnel, compliance with government regulations and the need to obtain additional financing to fund operations. Product candidates currently under development will require significant additional research and development efforts, including extensive preclinical studies, clinical studies and regulatory approval prior to commercialization. These efforts require significant amounts of additional resources, adequate personnel, infrastructure and extensive compliance and reporting.

The Company relies and expects to continue to rely on a small number of vendors to manufacture supplies and materials for use in its clinical trial programs. These programs could be adversely affected by a significant interruption in these manufacturing services.

#### Fair Value of Financial Instruments
The Company establishes the fair value of its assets and liabilities using the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date and established a fair value hierarchy based on the inputs used to measure fair value.

The carrying value of cash and cash equivalents, accounts payable and accrued liabilities approximate fair value due to their relatively short maturities. The Company determines the fair value of financial and non-financial assets and liabilities using the fair value hierarchy which establishes three levels of inputs that may be used to measure fair value (see Note 4).

#### Net Loss Per Share Attributable to Ordinary Shareholders
Basic net loss per ordinary share is calculated by dividing the net loss attributable to ordinary shareholders by the weighted-average number of ordinary shares, including non-voting ordinary shares, outstanding during the period, without consideration of potentially dilutive securities. Diluted net loss per ordinary share is computed by dividing the net loss attributable to ordinary shareholders by the weighted-average number of ordinary shares, including non-voting ordinary shares, and potentially dilutive securities outstanding for the period. For purposes of the diluted net loss per share calculation, the unvested restricted share units, ordinary shares committed under the employee share purchase plan and share options are considered to be potentially dilutive securities. Because the Company has reported a net loss for all periods presented, diluted net loss per ordinary share is the same as basic net loss per ordinary share for those periods.

#### Recent Accounting Pronouncements
*Accounting Pronouncements Not Yet Adopted*

In December 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-09, *Improvements to Income Tax Disclosures*. This ASU requires greater disaggregation of information about a reporting entity's effective tax rate reconciliation as well as information on income taxes paid. This ASU applies to all entities subject to income taxes and is intended to help investors better understand an entity's exposure to potential changes in jurisdictional tax legislation and assess income tax

[**Table of Contents**](#TOC)

STRUCTURE THERAPEUTICS INC.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

information that affects cash flow forecasts and capital allocation decisions. This ASU is effective for annual periods beginning after December 15, 2024, with early adoption permitted. This ASU should be applied on a prospective basis although retrospective application is permitted. The Company is currently evaluating the impact the adoption of this ASU will have on disclosures in its consolidated financial statements.

In November 2024, the FASB issued ASU 2024-03, *Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses*. This ASU requires additional information about a reporting entity's certain expense categories in the notes to financial statements in interim and annual reporting periods. Among other provisions, the new standard requires disclosure of disaggregated amounts for expenses such as employee compensation, depreciation, and intangible asset amortization included in each expense caption presented on the face of the income statement. This ASU is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact the adoption of this ASU will have on disclosures in its consolidated financial statements.

3. Composition of Certain Consolidated Financial Statement Line Items

Accrued expenses and other current liabilities consisted of the following (in thousands):

---

|:---|:---|:---|

| Accrued other liabilities | 6571 | 3606 |
| Total accrued expenses and other current liabilities | $36929 | $26299 |

---

4. Fair Value Measurements

The Company determines the fair value of financial and non-financial assets and liabilities using the fair value hierarchy which establishes three levels of inputs that may be used to measure fair value, as follows:

Level 1—Observable inputs, such as quoted prices in active markets for identical assets or liabilities;

Level 2—Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and

Level 3—Unobservable inputs which reflect management's best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model.

In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as considers counterparty credit risk in its assessment of fair value.

[**Table of Contents**](#TOC)

STRUCTURE THERAPEUTICS INC.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company's assessment of the significance of a particular input to the fair value measurement in its entirety requires management to make judgments and consider factors specific to the asset or liability.

The following tables present information about the Company's financial assets measured at fair value on a recurring basis and indicates the level of the fair value hierarchy utilized to determine such fair values (in thousands):

As of September 30, 2025 and December 31, 2024, the Company did not have any liabilities measured at fair value on a recurring basis. There were no transfers in and out of Level 3 during the three and nine months ended September 30, 2025 and 2024. The Company classifies its short-term investments as available-for-sale and records them at fair value based upon market prices at period end. Contractual maturities of short-term investments are generally not more than one year.

6. Shareholders' Equity

As of September 30, 2025, the Company's amended and restated memorandum and articles of association, authorizes the Company to issue 500,000,000 ordinary shares and 100,000,000 undesignated shares, all of which remain undesignated shares, all with a par value of $0.0001 per share. The undesignated shares may be designated by the Company's board of directors in accordance with the Company's amended and restated memorandum and articles of association.

Ordinary shareholders are entitled to dividends if and when declared by the Company's board of directors. As of September 30, 2025 and December 31, 2024, no dividends on ordinary shares had been declared by the board of directors.

*Performance Options*

In February 2023, the Company's board of directors approved the grant of performance share options for 1,200,000 ordinary shares, which were granted under the 2023 Equity Incentive Plan. Each share option would vest over four years, subject to the achievement of certain clinical milestones as determined by the Company's compensation committee in the first year following the grant, and subject to the employees' continuous service through each vesting date. The performance milestones were not achieved in the first year following the grant, and the performance share options were cancelled in February 2024. As such, no share-based compensation expense has been or will be recognized for such performance share options.

*Employee Share Purchase Plan*

In February 2023, the Company adopted the 2023 Employee Share Purchase Plan ("ESPP"). The Company allows eligible employees to purchase shares of the Company's ordinary shares through payroll deductions at a price equal to 85% of the lesser of the fair market value of the ordinary shares as of the first date of each offering period or the ending date of each purchase period. Each offering period is typically 24 months consisting of four purchase periods of six months. There were 1,000,000 ordinary shares initially reserved for issuance under the ESPP. In January 2025, the number of ordinary shares available for issuance under the ESPP was increased by 1,718,600 shares as a result of the automatic increase provision in the ESPP.

The offering period and purchase periods are determined by the board of directors. The Company issued 67,794 and 25,794 shares under the ESPP during the nine months ended September 30, 2025 and 2024, respectively. As of September 30, 2025, 3,974,754 shares under the ESPP remain available for purchase.

*Performance Share Units*

In March 2024, the Company granted 381,252 restricted share units with service and performance conditions to certain employees. The awards are divided into three equal tranches, and the vesting of each tranche was contingent on the occurrence of certain milestone events and fulfilment of service condition. As of December 31, 2024, the Company concluded that the two milestones were probable of achievement and therefore recognized compensation expense of $1.7 million during the year ended December 31, 2024. During the nine months ended September 30, 2025, the Company recognized compensation expense of $0.8 million. In June 2025, the Company's compensation committee certified the achievement of two of the three milestones, effective July 1, 2025. Because the third milestone was not achieved, the third tranche of performance share units was forfeited, effective July 1, 2025. As such, no share-based compensation expense has been or will be recognized for this third tranche of performance share units.

**Overview** 

We are a clinical stage global biopharmaceutical company developing novel oral small molecule therapeutics to treat a wide range of chronic diseases with unmet medical need. Our differentiated technology platform leverages both structure-based drug discovery and our expertise in computational chemistry to discover and develop small molecule therapeutics against G-protein coupled receptors ("GPCRs"). These important receptors regulate numerous and diverse physiological and pathological processes. In fact, approximately one in every three marketed medicines targets GPCR-associated pathways for the treatment of various metabolic, cardiovascular and pulmonary disorders. By leveraging our world-class GPCR know-how, we are designing differentiated small molecule therapies to overcome the limitations of biologics and peptide therapies that target this family of receptors.

Our most advanced product candidate to date is aleniglipron, also known as GSBR-1290, an oral small molecule selective glucagon-like-peptide-1 receptor ("GLP-1R") agonist currently in five ongoing clinical studies for the treatment of obesity, overweight and related conditions. We have two oral small molecule amylin receptor agonists, ACCG-2671 and ACCG-3535, which we have selected as development candidates. Our obesity pipeline also includes multiple preclinical discovery stage small molecules targeting glucose-dependent insulinotropic polypeptide ("GIP") and glucagon receptors and ANPA-0073, an oral small molecule agonist targeting the apelin ("APJ") receptor in good laboratory practices-toxicology studies, which is expected to be completed in 2025. Importantly, these programs have the potential to be developed as monotherapy as well as in fixed dose combination with our backbone therapeutics aleniglipron or our amylin development candidates. These combination products enable us to potentially address diseases beyond obesity including type 2 diabetes mellitus, heart failure, sleep apnea, chronic kidney disease, osteoarthritis, metabolic dysfunction-associated steatotic liver disease and potentially even addiction and Parkinson's disease and Alzheimer's disease, areas where we are starting to see encouraging data with GLP-1Rs. Our product candidates, as oral small molecules, have the potential to be more accessible medicines than biologics and peptide therapies with potentially differentiated efficacy and safety and, from a manufacturing standpoint, more scalable towards meeting global demand.

*Aleniglipron (GSBR-1290)*

In June 2024, we reported positive topline data from our Phase 2a obesity study, in which aleniglipron demonstrated a clinically meaningful and statistically significant placebo-adjusted mean decrease in weight of 6.2% at 12 weeks (p<0.0001, using least-squares means ("LSM") and analyzed based on the primary efficacy estimand using a mixed model for repeated measures) and demonstrated generally favorable safety and tolerability results following repeated, daily dosing up to 120 mg. Furthermore, we explored a new tablet formulation of aleniglipron in a capsule to tablet PK study, which demonstrated a placebo-adjusted mean weight loss of up to 6.9% with the tablet formulation at 12 weeks (p<0.0001, using LSM and analyzed based on the primary efficacy estimand using a mixed model for repeated measures). In July 2024, we submitted an

[**Table of Contents**](#TOC)

Investigational New Drug ("IND") to the U.S. Food and Drug Administration (the "FDA") to support initiation of a Phase 2b study in chronic weight management and received FDA allowance in August 2024.

In the fourth quarter of 2024, we initiated the Phase 2b ACCESS study, a randomized, double-blind, placebo-controlled, dose-range finding study of aleniglipron in approximately 220 adult participants living with obesity (body mass index ≥ 30 kg/m2), or overweight (body mass index ≥ 27 kg/m2) with at least one weight-related comorbidity. Participants start at 5 mg of aleniglipron (or placebo) with a four-week titration schedule, reaching target doses of 45 mg, 90 mg and 120 mg. The primary endpoint is percent change in body weight from baseline to week 36. Secondary endpoints include safety and tolerability of the monthly titration scheme, as well as pharmacokinetics of aleniglipron.

Also in the fourth quarter of 2024, we initiated a randomized, double-blind, placebo-controlled dose-range finding Phase 2 study, known as ACCESS II, evaluating two higher doses of aleniglipron in approximately 82 adult participants living with obesity or overweight with at least one weight-related comorbidity. Participants start at 5 mg of aleniglipron (or placebo) and follow a four-week titration schedule up to target doses of 120 mg, 180 mg and 240 mg.

In February 2025, we completed enrollment in both the ACCESS and ACCESS II studies, and expect to report topline data from both studies by year-end 2025.

In August 2025, we made multiple announcements regarding the following:

● The implementation of an open label extension to the ACCESS study – Patients in the study, including those who received aleniglipron and those in the placebo arm, have the option to roll over into the open label extension and receive aleniglipron after completing the double-blinded randomized portion of the study. This will allow collection of data on longer-term weight loss effects, expand the overall safety database and provide aleniglipron access to patients enrolled in the blinded portion of the study who opt into the extension.

● An extension to the ongoing ACCESS II study. Following the initial 36-week efficacy evaluation, patients will continue in the study to 44 weeks, which allows for collection of an additional eight weeks of double-blinded safety, tolerability, and efficacy data in the study. Overall, this extension will provide additional longer-term data in the two potentially higher dose arms of 180 mg and 240 mg. Per protocol and as previously planned, a formal unblinded efficacy assessment at 36 weeks is expected by year-end 2025.

● Three new aleniglipron studies – The studies are intended to generate additional data to competitively position aleniglipron and further support the design of the Phase 3 program. The three new aleniglipron studies are described below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. An ongoing maintenance switching study evaluating the transition from an approved injectable GLP-1 receptor agonist injectable to once-daily oral aleniglipron for weight loss maintenance. This study will assess the starting dose and the weight loss maintenance over 12 weeks. Enrollment is ongoing.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. A Phase 2 randomized placebo controlled study assessing the effect of aleniglipron on body fat loss measured via DEXA (dual-energy x-ray absorptiometry) over a 40-week evaluation period. These data will be used to support the inclusion of body composition endpoints into the Phase 3 program. The study is fully enrolled.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. A Phase 2 randomized placebo controlled study assessing aleniglipron at doses of up to 240mg in patients living with obesity or overweight and type 2 diabetes mellitus ("T2DM"). Data from the 38-week study will be used to support the inclusion of a cohort of patients with T2DM in the Phase 3 obesity program. Enrollment is ongoing.

*ACCG-2671 and ACCG-3535*

We are advancing our amylin receptor agonist oral small molecule program, and have declared ACCG-2671, a dual amylin calcitonin receptor agonist ("DACRA"), our lead development candidate. IND-enabling activities for ACCG-2671 are ongoing, with the initiation of a first-in-human Phase 1 clinical study expected by year-end 2025. Preclinical ACCG-2671 data presented at the American Diabetes Association 85<sup>th</sup> Scientific Sessions in June 2025 demonstrated high binding affinity and balanced potency in human calcitonin receptor and amylin receptor functional assays. In diet-induced obese rats, oral administration of ACCG-2671 resulted in significant, dose-dependent body weight reductions. Combination therapy with semaglutide (both as a subsequent add-on to semaglutide and as a concurrent treatment) resulted in superior weight loss compared to ACCG-2671 monotherapy.

In November 2025, we selected a second DACRA development candidate, ACCG-3535. ACCG-3535 is a unique chemical structure from ACCG-2671. Preclinical ACCG-3535 data were presented at Obesity Week 2025 demonstrating high binding affinity to human amylin and calcitonin receptors and balanced potency in human amylin and calcitonin receptor functional assays. In addition, ACCG-3535 demonstrated robust food intake suppression and significant, dose-dependent body weight reduction as a monotherapy in diet-induced obese rats. Combination therapy with semaglutide (both concurrently and as a subsequent add-on to semaglutide) resulted in superior weight loss compared to semaglutide or ACCG-3535 monotherapy.

*LTSE-2578*

In July 2025, we completed a Phase 1 single and multiple ascending dose clinical study of LTSE-2578, our oral small molecule antagonist that targets the lysophosphatidic acid 1 receptor ("LPA1R") for the treatment of idiopathic pulmonary fibrosis ("IPF"). The randomized, double-blind, placebo-controlled first-in-human clinical study investigated the safety, tolerability and pharmacokinetics of single and multiple ascending doses of LTSE-2578. In the study, there were no evidence of any dose-dependent LTSE-2578-related adverse events, including clinical, laboratory and electrocardiogram recordings. No serious adverse events were observed.

*ANPA-0073*

ANPA-0073 is our biased APJ receptor agonist. In September 2022, we completed a Phase 1 SAD and MAD study evaluating ANPA-0073 in healthy human volunteers, in which it was generally well tolerated. We are currently conducting long term GLP-toxicology studies of ANPA-0073, which is Phase 2 ready, to be used in combination with weight loss medicines for selective or muscle-sparing weight loss.

We are advancing a robust pipeline of small molecule therapeutic candidates for chronic diseases with unmet medical need.

![Graphic](gpcr-20250930x10q001.jpg)

We outsource clinical drug manufacturing, storage, distribution and quality testing to third-party manufacturers. We believe this strategy allows us to maintain a more efficient infrastructure by eliminating the need for us to invest in our own manufacturing facilities, equipment and personnel while also enabling us to focus our expertise and resources on the design and development of our product candidates. We have established a manufacturing plan in the United States and continue to contract in parallel with additional suppliers in the United States and other regions outside of China to diversify the manufacturing of our active pharmaceutical ingredient and drug product. As our development programs progress and we build new process efficiencies, we expect to continually evaluate this strategy with the objective of satisfying demand for registration studies and, if approved, the manufacture, sale and distribution of commercial products.

We are a Cayman Islands exempted company incorporated with limited liability. We were initially formed as a Delaware limited liability company in 2016 under the name ShouTi Inc., and reorganized as a Cayman Islands exempted company in February 2019. Our primary activities to date have included organizing and staffing our company, business and scientific planning, raising capital, conducting research and development activities, entering into strategic and corporate structuring transactions, enabling manufacturing activities in support of our product candidate development efforts, and establishing our intellectual property portfolio, and providing general and administrative support for these activities. We do not have any product candidates approved for sale and have not generated any revenue from our products. Since our inception, we have incurred net operating losses and negative cash flows from operations. We had net losses of $174.2 million and $86.0 million in the nine months ended September 30, 2025 and 2024, respectively. As of September 30, 2025, we had an accumulated deficit of $503.3 million. Historically, prior to our initial public offering ("IPO"), we have financed our operations primarily through the private placement of equity securities.

As of September 30, 2025, we have cash, cash equivalents and short-term investments of $799.0 million. Based on our current business plan, we estimate that our existing cash, cash equivalents and short-term investments will be sufficient to fund our projected operations and key clinical milestones through at least 2027. For aleniglipron, this includes costs related to the ongoing ACCESS and ACCESS II studies, extension studies, the supplementary studies, and Phase 3 readiness activities, but excludes Phase 3 registrational

[**Table of Contents**](#TOC)

studies. We have based this estimate on assumptions that may prove to be wrong, and we may exhaust our available capital resources sooner than we expect.

We expect to continue to incur significant and increasing expenses and operating losses for the foreseeable future, particularly if and as we continue to invest in our research and development activities and initiate additional clinical studies, expand our product pipeline, hire additional personnel and invest in and grow our business, maintain, expand and protect our intellectual property portfolio, and seek regulatory approvals for and commercialize any approved product candidates. In addition, we have incurred and expect to continue to incur additional costs associated with operating as a public company, including significant legal, audit, accounting, regulatory, consulting, and tax-related services associated with being a public company, compliance with Nasdaq listing and SEC requirements, director and officer insurance premiums and investor relations costs that we did not incur as a private company. As a result, we will need substantial additional capital to develop our product candidates, including to fund Phase 3 clinical studies of aleniglipron, and fund operations for the foreseeable future. Moreover, we may in the future seek to acquire or invest in additional businesses, products, or technologies that we believe could complement or enhance our products, enhance our technical capabilities or otherwise offer growth opportunities, although we currently have no agreements or understandings with respect to any such acquisitions or investments. Until such time as we can generate significant revenue from our products, if ever, we expect to finance our operations through the public or private sale of equity, government or private party grants, debt financings or other capital sources, including potential collaborations with other companies or other strategic transactions. If we are unable to obtain additional funding, we could be forced to delay, reduce or eliminate some or all of our research and development programs, product portfolio expansion or any commercialization efforts, which could adversely affect our business prospects, or we may be unable to continue operations. If we raise funds through strategic collaborations or other similar arrangements with third-parties, we may have to relinquish valuable rights to our platform technology, future revenue streams, research programs or product candidates or may have to grant licenses on terms that may not be favorable to us and/or may reduce the value of our ordinary shares. Because of the numerous risks and uncertainties associated with product development, we cannot predict the timing or amount of increased expenses or when or if we will be able to achieve or maintain profitability.

#### Impact of Geopolitical and Macroeconomic Factors
Although we did not see a significant financial impact to our business operations as a result of recent geopolitical and macroeconomic developments, such as recent and potential future disruptions in access to bank deposits or lending commitments due to bank failures, tariffs, global pandemics, geopolitical tensions between the United States and China, and various global conflicts for the nine months ended September 30, 2025, there may be potential impacts to our business in the future that are highly uncertain and difficult to predict, including our ability to raise additional funds, disruptions to the supply chain and the manufacture or shipment of drug substances and finished drug products for our product candidates for use in our research, preclinical studies and clinical studies, impediments to our clinical trial initiation and recruitment, errors or omissions at our clinical sites and the ability of patients to continue in clinical studies, delays in the FDA's review and approval processes including as a result of recent layoffs, our ability to effectively operate across different geographies in which our offices are located, any increases in interest rates and economic inflation, bank failures, the impact on the global economy due to various global conflicts, higher prices of supplies, tariffs, changes in monetary and fiscal policy, U.S. political developments and other sources of instability and changes in availability and cost of credit and our ability to access capital. The ultimate impact of these geopolitical and macroeconomic factors, as well as any lasting effects on the way we conduct our business, is highly uncertain and subject to continued change, and we recognize that they may continue to present unique challenges for us.

On July 4, 2025, the annual reconciliation bill, the One Big Beautiful Bill Act ("OBBBA") was signed into law, introducing significant changes to U.S. federal tax law. The new law repeals the requirement to capitalize domestic research and development ("R&D") expenditures for federal income tax purposes for taxable years beginning after December 31, 2024, and allows for the accelerated deduction of any remaining unamortized domestic R&D expenditures. Foreign R&D expenditures are still required to be capitalized and amortized

[**Table of Contents**](#TOC)

ratably over 15 years. The law also permanently allows one hundred percent bonus depreciation for qualified business property, including machinery, equipment, and certain improvements to nonresidential real property. We are evaluating the overall impact of OBBBA and preliminarily, we do not anticipate a material change to our effective income tax rate and net deferred federal income tax assets as we maintain a full valuation allowance.

#### Components of Our Results of Operations

#### Operating Expenses
*Research and Development*

Our research and development activities primarily consist of discovery, engineering and research associated with our product candidates under development, including preclinical studies and clinical studies. Research and development expenses include personnel-related costs for our management, including salaries, bonuses, benefits and share-based compensation expenses, consulting services, clinical trial expenses, regulatory expenses, publications, and allocated overhead expenses, including rent, equipment, depreciation, information technology costs and utilities.

We are focusing substantially all of our resources on the development of our product candidates and the discovery of new product candidates through our structure-based drug discovery platform. At this time, we cannot reasonably estimate or know the nature, timing and estimated costs of the efforts that will be necessary to complete the development of our product candidates.

We expect our research and development expenses to continue to account for a significant portion of our operating expenses, and to increase substantially for the foreseeable future as we advance our product candidates into and through preclinical and clinical studies, identify new product candidates and potentially pursue regulatory approval of our product candidates. We anticipate that we will make determinations as to which product candidates to pursue and how much funding to direct to each product candidate on an ongoing basis in response to the results of ongoing and future preclinical and clinical studies, such as to conduct Phase 3 clinical studies of aleniglipron.

*General and Administrative*

Our general and administrative expenses consist primarily of personnel-related costs for personnel in executive, legal, finance and other administrative functions, including salaries, bonuses, benefits and share-based compensation expenses, professional fees for legal, consulting, accounting and tax services, allocated overhead expenses, including rent, equipment, depreciation, information technology costs and utilities, and other general operating expenses not otherwise classified as research and development expenses.

We expect our general and administrative expenses will increase during the next several years as we increase our headcount and expand our infrastructure to support our operations, particularly as a public company. In addition, as a public company, we have incurred and will continue to incur significant legal, accounting, investor relations and other expenses to comply with the reporting requirements of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), the listing standards of Nasdaq, the Sarbanes-Oxley Act, and other applicable securities rules and regulations. Our general and administrative expenses may fluctuate from period to period as we continue to grow.

#### Interest and Other Income, Net
Interest and other income, net primarily consists of interest income earned on our cash, cash equivalents and short-term investments, including amortization and accretion of premiums and discounts on short-term investments and foreign currency exchange gains and losses.

*General and Administrative Expenses*

General and administrative expenses increased by $1.6 million, or 12%, to $14.8 million during the three months ended September 30, 2025, compared to $13.2 million during the three months ended September 30, 2024. The increase in general and administrative expenses was primarily due to increases in employee expenses as we expanded our infrastructure to drive and support the growth in our operations as a publicly-traded company.

[**Table of Contents**](#TOC)

*Interest and Other Income, Net*

Interest and other income, net, decreased by $3.8 million to an income of $8.2 million during the three months ended September 30, 2025, compared to an income of $12.0 million during the three months ended September 30, 2024. The decrease in interest and other income, net, was primarily due to a decrease in interest income from lower cash, cash equivalents and short-term investment balances and lower interest rates.

*General and Administrative Expenses*

General and administrative expenses increased by $8.2 million, or 23%, to $44.0 million during the nine months ended September 30, 2025, compared to $35.8 million during the nine months ended September 30, 2024. The increase in general and administrative expenses was primarily due to increases in employee expenses as we expanded our infrastructure to drive and support the growth in our operations as a publicly-traded company.

*Interest and Other Income, Net*

Interest and other income, net, increased by $1.4 million to an income of $26.7 million during the nine months ended September 30, 2025, compared to an income of $25.3 million during the nine months ended September 30, 2024. The increase in interest and other income, net, was primarily due to an increase in interest income from higher cash, cash equivalents and short-term investment balances.

#### Liquidity and Capital Resources
From our reorganization as a Cayman Islands exempted company in February 2019 through immediately prior to completion of our IPO, we funded our operations primarily with an aggregate of $198.0 million in gross cash proceeds from the sale of redeemable convertible preferred shares. In connection with the closing of our IPO in February 2023, we issued and sold an aggregate of 12,351,000 American Depositary Shares ("ADSs") (inclusive of 1,611,000 ADSs pursuant to the exercise by the underwriters of their option) at a price of $15.00 per ADS for net cash proceeds of approximately $166.7 million, net of underwriting discounts and commissions and estimated offering costs. In September 2023, we entered into a share purchase agreement with certain institutional investors (the "Purchasers"), pursuant to which we agreed to sell and issue to the Purchasers an aggregate of 21,617,295 ordinary shares and 2,401,920 newly designated non-voting ordinary shares at a purchase price of $12.49 per share (or the equivalent of $37.47 per ADS), the closing price of our ADS on the Nasdaq Global Market on September 28, 2023 (the "Private Placement"). We completed the Private Placement in October 2023 and received approximately $281.5 million in net proceeds after deducting placement agent fees and other private placement expenses. In June 2024, we issued and sold 10,427,017 ADSs at a price of $52.50 per ADS, including the full exercise of the underwriters' option to purchase up to an aggregate of 1,360,045 additional ADSs, and received $512.7 million in net proceeds, after deducting the underwriting discounts and commissions and estimated offering expenses (the "Follow-On Offering"). In August 2025, we entered into a sales agreement (the "ATM Sales Agreement") with Leerink Partners LLC and Cantor Fitzgerald & Co. (the "ATM Sales Agents"), pursuant to which we may, from time to time, offer and sell our ADSs through the ATM Sales Agents in any manner deemed to be an "at-the-market" offering up to an aggregate offering price of $250.0 million (the "ATM Offering"). In September 2025, we sold 3,040,000 ADSs under the ATM Sales Agreement, for gross proceeds of approximately $58.5 million. The net proceeds after deducting sales commissions to the ATM Sales Agents were approximately $57.1 million, and, after further deducting offering expenses were approximately $55.8 million. As of September 30, 2025, we had cash, cash equivalents and short-term investments of $799.0 million and an accumulated deficit of $503.3 million.

#### Funding Requirements
Since our inception, we have incurred net operating losses and negative cash flows from operations. We had net losses of $174.2 million and $86.0 million in the nine months ended September 30, 2025 and 2024, respectively. As of September 30, 2025, we had an accumulated deficit of $503.3 million. Our primary activities to date have included organizing and staffing our company, business and scientific planning, raising capital, conducting research and development activities, entering into strategic and corporate structuring transactions, enabling manufacturing activities in support of our product candidate development efforts, establishing our intellectual property portfolio, and providing general and administrative support for these activities.

[**Table of Contents**](#TOC)

As of September 30, 2025, we had cash, cash equivalents and short-term investments of $799.0 million. Based on our current business plan, we believe that our existing cash, cash equivalents and short-term investments will be sufficient to fund our projected operations for at least the next 12 months from the date of the issuance of our condensed consolidated financial statements. We have based this estimate on assumptions that may prove to be wrong, and we may exhaust our available capital resources sooner than we expect.

To date, we have not generated any revenue from our products. We do not expect to generate any significant product revenue until we successfully develop and obtain regulatory approval for and commercialize our product candidates, and we do not know when, or if, either will occur. We expect to continue to incur significant and increasing expenses and operating losses for the foreseeable future, particularly if and as we continue to invest in our research and development activities and initiate additional clinical studies, expand our product pipeline, hire additional personnel and invest in and grow our business, maintain, expand and protect our intellectual property portfolio, and seek regulatory approvals for and commercialize any approved product candidates. In addition, we have incurred and expect to continue to incur additional costs associated with operating as a public company, including significant legal, audit, accounting, regulatory, tax-related, director and officer insurance, investor relations and other expenses that we did not incur as a private company. Moreover, we may in the future seek to acquire or invest in additional businesses, products, or technologies that we believe could complement or enhance our products, enhance our technical capabilities or otherwise offer growth opportunities, although we currently have no agreements or understandings with respect to any such acquisitions or investments. We are subject to the risks typically related to the development of new product candidates, and we may encounter unforeseen expenses, difficulties, complications, delays and other unknown factors that may adversely affect our business.

We will need substantial additional capital to develop our product candidates, including to fund Phase 3 clinical studies of aleniglipron, and fund operations for the foreseeable future. Our future capital requirements will depend on many factors, including:

● the scope, timing, rate of progress and costs of our preclinical development activities, laboratory testing and clinical studies for our product candidates;

● the number and scope of clinical programs we decide to pursue;

● the cost, timing and outcome of preparing for and undergoing regulatory review of our product candidates;

● the cost and timing of manufacturing our product candidates;

● the cost and timing associated with commercializing our product candidates, if they receive marketing approval;

● the extent to which we acquire or in-license other product candidates and technologies;

● the costs of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending intellectual property-related claims;

● our ability to establish and maintain collaborations on favorable terms, if at all;

● our efforts to enhance operational systems and our ability to attract, hire and retain qualified personnel, including personnel to support the development of our product candidates and, ultimately, the sale of our products, following FDA approval;

● our implementation of operational, financial and management systems; and

● the impact of geopolitical and macroeconomic events, including tariffs, future bank failures, increased geopolitical tensions between the United States and China, various global conflicts and global pandemics on U.S. and global economic conditions including changes in monetary and fiscal policy,

[**Table of Contents**](#TOC)

tax laws, U.S. political developments and other sources of instability that may impact our ability to access capital on acceptable terms, if at all.

A change in the outcome of any of these or other variables with respect to the development of our product candidates could significantly change the costs and timing associated with the development of that product candidate. Furthermore, our business plans may change in the future, and we will continue to require additional capital to meet operational needs and capital requirements associated with such plans.

Until such time we can generate significant revenue from product sales, if ever, we expect to finance our operations through the public or private sale of equity, government or private party grants, debt financings or other capital sources, including potential collaborations with other companies or other strategic transactions. To the extent that we raise additional capital through the sale of equity or convertible debt securities, your ownership interest may be diluted, and the terms of these securities may include liquidation or other preferences and anti-dilution protections that could adversely affect your rights as a holder of our ADSs. Additional debt or preferred equity financing, if available, may involve agreements that include restrictive covenants that may limit our ability to take specific actions, such as incurring debt, making capital expenditures or declaring dividends, which could adversely impact our ability to conduct our business, and may require the issuance of warrants, which could potentially dilute your ownership interest. If we raise funds through strategic collaborations or other similar arrangements with third-parties, we may have to relinquish valuable rights to our platform technology, future revenue streams, research programs or product candidates or may have to grant licenses on terms that may not be favorable to us and/or may reduce the value of our ordinary shares.

If we are unable to obtain additional funding, or funding on acceptable terms, we could be forced to delay, reduce or eliminate some or all of our research and development programs, product portfolio expansion or any commercialization efforts, which could adversely affect our business prospects, or we may be unable to continue operations. Because of the numerous risks and uncertainties associated with product development, we cannot predict the timing or amount of increased expenses or when or if we will be able to achieve or maintain profitability.

*Cash Flows Used in Operating Activities*

During the nine months ended September 30, 2025, net cash used in operating activities was $157.8 million, consisting of a net loss of $174.2 million, partially offset by a decrease in net operating assets of $5.8 million and non-cash charges of $10.6 million. The increase in net loss was primarily due to the increase in operating expenses as we invest in our research and development efforts. The decrease in net operating assets was primarily due to an increase in accrued expenses and other current liabilities and an increase in accounts payable, partially offset by an increase in prepaid expenses and other current assets, an increase in other

[**Table of Contents**](#TOC)

non-current assets and a decrease in operating lease liabilities. Non-cash charges consisted primarily of share-based compensation and non-cash lease expense, partially offset by net gain from accretion of net investment discounts.

During the nine months ended September 30, 2024, net cash used in operating activities was $80.2 million, consisting of a net loss of $86.0 million, partially offset by non-cash charges of $2.4 million and a decrease in net operating assets of $3.5 million. The increase in net loss was primarily due to the increase in operating expenses as we invest in our research and development efforts and operate as a publicly-traded company. Non-cash charges consisted primarily of share-based compensation and non-cash lease expenses, partly offset by net gain from accretion of net investment discounts. The decrease in net operating assets was primarily due to an increase in accrued expenses and other current liabilities and accounts payable, partly offset by an increase in prepaid expenses and other current assets, an increase in other non-current assets and a decrease in operating lease liabilities.

*Cash Flows Provided by (Used in) Investing Activities*

During the nine months ended September 30, 2025, net cash provided by investing activities was $33.7 million, consisting primarily of net maturities of short-term investments of $30.6 million, and advance payment received for sale of non-financial asset of $5.2 million.

During the nine months ended September 30, 2024, net cash used in investing activities was $392.1 million, consisting primarily of net purchases of short-term investments.

*Cash Flows Provided by Financing Activities*

During the nine months ended September 30, 2025, net cash provided by financing activities was $57.5 million, consisting primarily of proceeds from our sales under the ATM Offering of $57.1 million, net of sales commission.

During the nine months ended September 30, 2024, net cash provided by financing activities was $514.6 million, consisting primarily of proceeds from our Follow-On Offering of $514.6 million, net of underwriting discounts and commissions.

#### Contractual Obligations
As of September 30, 2025, our contractual obligations consist of facilities lease payments totaling $7.9 million, with $3.2 million expected to be paid within the next 12 months. See "Operating Leases" in Note 5 to our unaudited interim condensed consolidated financial statements in Part I. Item 1 "Financial Statements" in this Quarterly Report for additional information.

#### Critical Accounting Policies
Our condensed consolidated financial statements have been prepared in accordance with U.S. Generally Accepted Accounting Principles ("GAAP"). The preparation of our condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities as of the date of the condensed consolidated financial statements and the reported expenses incurred during the reporting periods. Our estimates are based on our knowledge of current events and actions we may undertake in the future and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may materially differ from these estimates under different assumptions or conditions.

Our critical accounting policies and estimates are described in Part II. Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations - Critical Accounting Policies and Significant Judgments and Estimates" in our Annual Report. There were no material changes to these accounting policies during the nine months ended September 30, 2025.

#### Recent Accounting Pronouncements
**See "Recent Accounting Pronouncements" in Note 2 to our unaudited interim condensed consolidated financial statements included in Part I. Item 1 "Financial Statements" in this Quarterly Report for additional information.**

#### Item 3. Quantitative and Qualitative Disclosures About Market Risk.
Our quantitative and qualitative disclosures about market risk are described in Part II. Item 7A. "Quantitative and Qualitative Disclosures About Market Risk" in our Annual Report. There were no material changes to these quantitative and qualitative disclosures about market risk during the nine months ended September 30, 2025.

**Item 4. Controls and Procedures.**

**Evaluation of Disclosure Controls and Procedures**

Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, has evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of September 30, 2025, which is the end of the period covered by this Quarterly Report. These disclosure controls and procedures are designed to provide reasonable assurance that information required to be disclosed in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and our Chief Financial Officer, to allow timely decisions regarding required disclosure.

Based on that evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that, as of September 30, 2025, our disclosure controls and procedures were effective at the reasonable assurance level.

**Changes in Internal Control Over Financial Reporting**

There were no changes in our internal control over financial reporting identified in management's evaluation pursuant to Rules 13a-15(f) or 15d-15(f) of the Exchange Act during the quarter ended September 30, 2025 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

**Limitations on Effectiveness of Disclosure Controls and Procedures**

A system of internal control over financial reporting is intended to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements in accordance with GAAP and no control system, no matter how well designed and operated, can provide absolute assurance. The design of any control system is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Because of its inherent limitations, internal control over financial reporting may not prevent or detect financial statement errors and misstatements. Also, projection of any evaluation of effectiveness to future periods is 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.

**PART II. OTHER INFORMATION**

**Item 1. Legal Proceedings.**

To the best of our knowledge, we are not currently the subject of any material governmental investigation, private lawsuit or other legal proceeding. From time to time, we are and may in the future be involved in legal and regulatory proceedings or investigations concerning matters that arise in the ordinary course of our business and that could result in significant fines or penalties, have an adverse impact on our reputation, business and financial condition or results of operations and divert the attention of our management from the operation of our business.

#### Item 1A. Risk Factors.
*Investing in our securities, involves a high degree of risk. You should carefully consider the risks and uncertainties described below, together with all of the other information contained in this Quarterly Report, including our consolidated financial statements and their related notes included in Part I. Item 1 "Financial Statements" of this Quarterly Report and Part I. Item 2. "Management's Discussion and Analysis of Financial Condition and Results of Operations" before making an investment decision. If any of the following risks actually occurs, our business, prospects, operating results and financial condition could suffer materially, the trading price of our ADSs could decline and you could lose all or part of your investment. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently believe to be immaterial also may materially and adversely affect our business, prospects, operating results and financial condition.*

#### Risks Related to Our Limited Operating History, Financial Position and Capital Requirements
***We have a limited operating history, have incurred significant operating losses since our inception and expect to incur significant losses for the foreseeable future.***

Biopharmaceutical product development is a highly speculative undertaking and involves a substantial degree of risk. We are a clinical stage biopharmaceutical company with a limited operating history, which may make it difficult to evaluate the success of our business to date and assess our future viability. Since our inception in 2016, we have focused primarily on organizing and staffing our company, business planning, establishing our intellectual property portfolio, raising capital, developing our structure-based drug discovery platform, identifying and developing our product candidates, conducting preclinical studies and, more recently, clinical studies, and providing general and administrative support for these operations. Our approach to the discovery and development of product candidates based on our structure-based drug discovery platform is unproven, and we do not know whether we will be able to develop any product candidates that succeed in clinical development or commercially. Further, aleniglipron, our product candidate for obesity, overweight and related conditions, ACCG-2671 and ACCG-3535, our oral small molecule amylin receptor agonist development candidates for the treatment of obesity, ANPA-0073, our product candidate for selective or muscle-sparing weight loss, and LTSE-2578, our product candidates for IPF, are in early clinical development and our other product candidates and programs are in preclinical development or discovery stages. Accordingly, we have not yet demonstrated an ability to successfully obtain regulatory approvals, manufacture a commercial scale product or arrange for a third party to do so on our behalf, or conduct sales and marketing activities necessary for successful product commercialization. Consequently, any predictions made about our future success or viability may not be as accurate as they could be if we had a history of successfully developing and commercializing biopharmaceutical products.

[**Table of Contents**](#TOC)

We have no products approved for commercial sale and have not generated any revenue to date, and we continue to incur significant research and development and other expenses related to our ongoing operations. As a result, we are not profitable and have incurred significant losses since our inception and expect to continue to incur significant and increasing operating losses for at least the next several years. Our net losses were $174.2 million and $122.5 million for the nine months ended September 30, 2025 and year ended December 31, 2024, respectively. As of September 30, 2025, we had an accumulated deficit of $503.3 million. Substantially all of our losses have resulted from expenses incurred in connection with our research and development programs and from general and administrative costs associated with our operations. All of our product candidates will require substantial additional development time and resources, including additional funding to conduct Phase 3 clinical studies of aleniglipron, before we would be able to apply for or receive marketing approvals and begin generating revenue from product sales. We expect to continue to incur losses for the foreseeable future, and we anticipate that our expenses will increase substantially as we continue our development of, seek marketing approval for and potentially commercialize any of our product candidates, recruit and maintain key personnel and seek to identify, assess, acquire, in-license or develop additional product candidates.

Even if we succeed in developing and obtaining marketing approval for one or more product candidates, we may never generate revenue that is significant enough to achieve profitability. If we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis and we will continue to incur substantial R&D and other expenditures to develop and market additional product candidates. Our failure to become and remain profitable could decrease the value of our ADSs and impair our ability to raise capital, maintain our research and development efforts, expand our business or continue our operations.

***We will require substantial additional capital to finance our operations, which may not be available on acceptable terms, or at all. Failure to obtain this necessary capital when needed may force us to delay, limit or terminate certain of our product development programs, commercialization efforts or other operations.***

The development of biopharmaceutical product candidates is capital-intensive. We expect our expenses to increase substantially in connection with our ongoing and planned activities, particularly as we conduct our ongoing and planned preclinical studies and clinical studies of aleniglipron, ACCG-2671, ACCG-3535, ANPA-0073, LTSE-2578 and any future product candidates we may develop. Our expenses will increase substantially if any of our product candidates successfully complete early clinical and other studies, and also could increase beyond expectations if the FDA or foreign authorities require us to perform clinical and other studies in addition to those that we currently anticipate. Because the outcome of any clinical trial or preclinical study is highly uncertain, we cannot reasonably estimate the actual amounts necessary to successfully complete the development and commercialization of our product candidates. In addition, we have and expect to continue to incur additional costs associated with operating as a public company. Furthermore, if we obtain marketing approval for our product candidates, we expect to incur significant expenses related to manufacturing, marketing, sales and distribution. Accordingly, we will need to obtain substantial additional funding in connection with our continuing operations. If we are unable to raise capital when needed or on attractive terms, we could be forced to delay, reduce or eliminate our research and development programs or any future commercialization efforts.

Based on our current operating plan, we believe that our cash, cash equivalents and short-term investments, as of September 30, 2025, will be sufficient to fund our operating expenses and key clinical milestones through at least 2027. For aleniglipron, this includes costs related to the ongoing ACCESS and ACCESS II studies, extension studies, the supplementary studies, and Phase 3 readiness activities, but excludes Phase 3 registrational studies. We have based these estimates on assumptions that may prove to be wrong, and we could use our capital resources sooner than we currently expect. Our operating plan may change as a result of many factors currently unknown to us, and we may need to seek additional funds sooner than planned, through equity offerings, debt financings or other capital sources, including potentially grants, collaborations, licenses and other similar arrangements. Even if we believe we have sufficient capital for our current or future

[**Table of Contents**](#TOC)

operating plans, we may seek additional capital if market conditions are favorable or if we have specific strategic considerations.

Any additional capital raising efforts may divert our management from their day-to-day activities, which may adversely affect our ability to develop and, if approved, commercialize our current and any future product candidates. Additional funding may not be available on acceptable terms, or at all. As a result of actual or anticipated changes in interest rates, economic inflation and tariffs, changes in monetary and fiscal policy, United States political developments and other sources of instability, the impact of various global conflicts, the global credit and financial markets have experienced extreme volatility and disruptions, including severely diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth, inflation, bank failures, trade wars, increases in unemployment rates, and uncertainty about economic stability. If the equity and credit markets deteriorate, it may make any necessary debt or equity financing more difficult to obtain in a timely manner or on favorable terms, more costly or more dilutive.

Our future funding requirements will depend on many factors, including:

● the progress, costs, design, results of and timing of our planned and ongoing preclinical studies and clinical studies, including Phase 3 clinical studies of aleniglipron;

● the willingness of the FDA or applicable foreign authorities to accept our clinical studies, as well as data from our planned and ongoing preclinical studies and clinical studies and other work, as the basis for review and approval of our product candidates;

● the outcome, costs and timing of seeking and obtaining FDA and applicable foreign regulatory approvals;

● the number and characteristics of product candidates that we pursue;

● our need to expand our research and development capabilities, including further development of our structure-based drug discovery platform or in-licensing of complementary technologies;

● the costs and timing associated with manufacturing our product candidates, and establishing commercial supplies and sales, marketing, and distribution capabilities;

● our efforts to maintain, expand, and defend the scope of our intellectual property portfolio, including the amount and timing of any payments we may be required to make, or that we may receive, in connection with the licensing, filing, prosecution, defense, and enforcement of any patents or other intellectual property rights;

● our need and ability to retain key management and hire scientific, technical, business, and medical personnel;

● our need to implement additional internal systems and infrastructure, including financial and reporting systems;

● the costs associated with operating as a public company;

● the economic and other terms, timing of and success of our current and any future collaboration, licensing or other arrangements which we may enter in the future; and

● the timing, receipt, and amount of sales from our potential products, if approved.

If we are unable to raise additional capital 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 product candidates that we would otherwise prefer to develop and market ourselves, and our ability to grow and support our business and to respond to market challenges could be significantly limited, which could have a material adverse effect on our business, financial condition and results of operations.

[**Table of Contents**](#TOC)

***Raising additional capital may cause dilution to our shareholders, restrict our operations or require us to relinquish rights to our technologies or product candidates.***

Until such time, if ever, as we can generate substantial product revenue, we expect to finance our operations through equity offerings, debt financings or other capital sources, including potentially grants, collaborations, licenses or other similar arrangements. For example, in October 2023, we issued and sold an aggregate of 21,617,295 ordinary shares and 2,401,920 newly designated non-voting ordinary shares in the Private Placement. In June 2024, we issued and sold an aggregate of 10,427,017 ADSs in the Follow-On Offering. On August 6, 2025, we entered into the ATM Sales Agreement with the ATM Sales Agents, pursuant to which we may, from time to time, offer and sell our ADSs up to an aggregate offering price of $250.0 million. During the three months ended September 30, 2025, we sold 3,040,000 ADSs under the ATM Sales Agreement, for gross proceeds of approximately $58.5 million. As of September 30, 2025, approximately $191.5 million remained available for sale under the ATM Sales Agreement. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our shareholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our ADS holders. Debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as limitations on our ability to incur additional debt, make capital expenditures or declare dividends. If we raise funds through collaborations or licensing arrangements with third parties, we may be required to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or grant licenses on terms that may not be favorable to us.

#### Risks Related to the Discovery, Development and Regulatory Approval of Product Candidates
***Our approach to the discovery of product candidates based on our technology platform is unproven, and we do not know whether we will be able to develop any products of commercial value.***

The success of our business depends primarily upon our ability to identify novel product candidates based on our structure-based drug discovery platform and to successfully develop and commercialize those product candidates. While we have had favorable preclinical study and topline clinical trial results for certain of our development programs, we have not yet succeeded and may not succeed in demonstrating efficacy and safety for any product candidates in clinical studies or in obtaining marketing approvals or in commercializing such product candidates. We also may be unsuccessful in identifying additional product candidates using our platform, and any of our product candidates may be shown to have harmful side effects or may have other characteristics that may necessitate additional clinical testing, or make the product candidates unmarketable or unlikely to receive marketing approval. In particular, because all of our product candidates have been derived from our structure-based drug discovery platform, any failure of one of our development programs could create a perception that our other programs are less likely to succeed or that our discovery platform is not viable. Similarly, adverse developments with respect to other companies that attempt to use a similar approach to our approach may adversely impact the actual or perceived value and potential of our discovery platform and resulting product candidates.

If any of these events occur, our ability to successfully discover, develop and commercialize any product candidates may be impaired and the value of our company could decline significantly.

[**Table of Contents**](#TOC)

***We are early in our development efforts and only have three product candidates, aleniglipron, ANPA-0073 and LTSE-2578, in early clinical development. All of our other development programs are in the preclinical or discovery stage. If we are unable to advance our product candidates in clinical development, obtain regulatory approval and ultimately commercialize our product candidates, or experience significant delays in doing so, our business will be materially harmed.***

We are in the early stages of our development efforts and have three product candidates, aleniglipron, ANPA-0073 and LTSE-2578, in early clinical development. In June 2024, we reported positive topline data from our Phase 2a obesity study, in which aleniglipron demonstrated a clinically meaningful and statistically significant placebo-adjusted mean decrease in weight of 6.2% at 12 weeks (p<0.0001, using least-squares means ("LSM") and analyzed based on the primary efficacy estimand using a mixed model for repeated measures) and demonstrated generally favorable safety and tolerability results following repeated, daily dosing up to 120 mg. Furthermore, we explored a new tablet formulation of aleniglipron in a capsule to tablet PK study, which demonstrated a placebo-adjusted mean weight loss of up to 6.9% with the tablet formulation at 12 weeks (p<0.0001, using LSM and analyzed based on the primary efficacy estimand using a mixed model for repeated measures). In July 2024, we submitted an IND to the FDA to support the initiation of a Phase 2b study in chronic weight management and received FDA allowance in August 2024. In the fourth quarter of 2024, we initiated the Phase 2b ACCESS study, a randomized, double-blind, placebo-controlled, dose-range finding study of aleniglipron in approximately 220 adult participants living with obesity (BMI ≥ 30 kg/m2), or overweight (BMI ≥ 27 kg/m2) with at least one weight-related comorbidity. Participants start at 5 mg of aleniglipron (or placebo) with a four-week titration schedule, reaching target doses of 45 mg, 90 mg and 120 mg. The primary endpoint is percent change in body weight from baseline to week 36. Secondary endpoints include safety and tolerability of the monthly titration scheme, as well as PK of aleniglipron. In the fourth quarter of 2024, we initiated a randomized, double-blind, placebo-controlled dose-range finding Phase 2 study of aleniglipron, known as ACCESS II, in approximately 82 adult participants living with obesity or overweight with at least one weight-related comorbidity. The study is designed to evaluate two higher doses of aleniglipron. Participants start at 5 mg of aleniglipron (or placebo) and follow a four-week titration schedule up to target doses of 120 mg, 180 mg and 240 mg. In February 2025, we completed enrollment in the ACCESS and ACCESS II studies, and we expect to report topline data from both studies by year-end 2025.

In August 2025, we announced the implementation of an open label extension to the ACCESS study. Patients in the study, including those who received aleniglipron and those in the placebo arm, have the option to roll over into the open label extension and receive aleniglipron after completing the double-blinded randomized portion of the study. Additionally, we announced an extension to the ongoing ACCESS II study. Following the initial 36-week efficacy evaluation, patients continue in the study to 44 weeks, which allows for collection of an additional eight weeks of double-blinded safety, tolerability, and efficacy data in the study. Per protocol and as previously planned, a formal unblinded efficacy assessment at 36 weeks is expected by year-end 2025. Lastly, we announced that we are conducting three new aleniglipron studies that are intended to generate additional data to competitively position aleniglipron and further support the design of the Phase 3 program. The three new aleniglipron studies are the following: (1) a maintenance switching study evaluating the transition from an approved injectable GLP-1 receptor agonist to once-daily oral aleniglipron for weight loss maintenance; (2) a Phase 2 study assessing the effect of aleniglipron on body fat loss over a 40-week evaluation period; and (3) a Phase 2 study assessing the effects of aleniglipron on patients with obesity or overweight and T2DM.

In July 2025, we completed a Phase 1 single and multiple ascending dose clinical trial of LTSE-2578. The randomized, double-blind, placebo-controlled first-in-human clinical study investigated the safety, tolerability and pharmacokinetics of single and multiple ascending doses of LTSE-2578. In the study, there was no evidence of any dose-dependent LTSE-2578-related adverse events, including clinical, laboratory and electrocardiogram recordings. No serious adverse events were observed in the study.

Our other product candidates are still in the preclinical or discovery stages. We will need to progress early product candidates through preclinical studies and submit INDs to the FDA or appropriate regulatory documents to applicable foreign authorities prior to initiating their clinical development. Our ability to generate

[**Table of Contents**](#TOC)

product revenues, which we do not expect will occur for many years, if ever, will depend heavily on the successful development and eventual commercialization of our product candidates. The success of our product candidates will depend on several factors, including the following:

● completion of preclinical studies with favorable results;

● successful enrollment in, and completion of, clinical studies;

● sufficiency of our financial and other resources to complete the necessary preclinical studies and clinical studies;

● allowance to proceed with clinical studies under INDs by the FDA or under similar regulatory submissions by applicable foreign authorities for the conduct of clinical studies of our product candidates and our proposed design of future clinical studies;

● demonstrating the safety and efficacy of our product candidates to the satisfaction of applicable regulatory authorities;

● receipt of regulatory approvals from applicable regulatory authorities, including NDAs from the FDA and maintaining such approvals;

● making arrangements with third-party manufacturers, or establishing clinical and commercial manufacturing capabilities for our product candidates;

● establishing sales, marketing and distribution capabilities and launching commercial sales of our products, if and when approved, whether alone or in collaboration with others;

● establishing and maintaining patent and trade secret protection or regulatory exclusivity for our product candidates;

● acceptance of any products we develop and their benefits and uses, if and when approved, by patients, the medical community and third-party payors;

● effectively competing with other therapies;

● obtaining and maintaining healthcare coverage and adequate reimbursement from third-party payors;

● maintaining an acceptable safety profile of our products following approval; and

● building and maintaining an organization of people who can successfully develop our product candidates.

We have not yet succeeded and may not succeed in demonstrating efficacy and safety for any product candidates in clinical studies or in obtaining marketing approval thereafter. Given our early stage of development, it will take several years before we can demonstrate the safety and efficacy of a product candidate sufficient to warrant approval for commercialization, if we can do so at all. If we are unable to develop, or obtain marketing approval for, or, if approved, successfully commercialize our product candidates, we may not be able to generate sufficient revenue to continue our business.

***Clinical and preclinical drug development involves a lengthy and expensive process with uncertain timelines and outcomes. The results of prior clinical studies and preclinical studies are not necessarily predictive of future results, and may not be favorable, or receive regulatory approval on a timely basis, if at all.***

Clinical drug development is expensive and can take many years to complete, and its outcome is inherently uncertain. Our clinical studies may not be conducted as planned or completed on schedule, if at all, and failure can occur at any time during the preclinical study or clinical trial process. For example, we depend on the availability of non-human primates ("NHPs") to conduct certain preclinical studies that we are required to complete prior to submitting an IND and initiating clinical development. There is currently a global shortage of

[**Table of Contents**](#TOC)

NHPs available for drug development. This has caused the cost of obtaining NHPs for our preclinical studies to increase dramatically and, if the shortage continues, could also result in delays to our development timelines. Despite promising preclinical or clinical results, any product candidate can unexpectedly fail at any stage of preclinical or clinical development. The historical failure rate for product candidates in our industry is high. Furthermore, the results from clinical studies or preclinical studies of a product candidate may not predict the results of later clinical studies of the product candidate, and interim results of a clinical trial are not necessarily indicative of final results. For example, the preliminary topline nature of aleniglipron results, the length of the study and sample size may render these results not necessarily indicative of the results for our future clinical studies for aleniglipron and may not be comparable to other weight loss products or product candidates, including other oral selective GLP-1RAs. In addition, given the size of the Phase 2a obesity cohort, the primary efficacy endpoint of weight loss was calculated using LSM and analyzed based on the primary efficacy estimand using a mixed model for repeated measures. This means that we drew on all available data, including data from patients that did not follow-up at 12 weeks. The model estimates how patients with missing data would have responded based on patients who continued the study and had similar baseline characteristics (implicit imputation). Product candidates in later stages of clinical studies may fail to show the desired safety and efficacy characteristics despite having progressed through preclinical studies and initial clinical studies. In particular, while we have conducted, or are conducting certain preclinical studies of our product candidates, the predictive value of these studies with respect to future testing in humans is limited, particularly in indications where animal models are less developed.

Even if our clinical studies are completed, the results may not be sufficient to obtain marketing approval for our product candidates. In clinical studies that are based on preclinical studies and early clinical studies, it is not uncommon to observe unexpected results, and many product candidates fail in clinical development despite very promising early results. Moreover, preclinical and clinical data may be susceptible to varying interpretations and analyses. A number of companies in the biopharmaceutical industry have suffered significant setbacks in clinical development even after achieving promising results in earlier studies. In addition, in some cases, external experts or regulatory authorities disagreed with such companies' views and interpretations of the data and results from earlier preclinical studies or clinical studies. As we investigate aleniglipron for obesity, overweight and related conditions, ACCG-2671 and ACCG-3535 for obesity and overweight, ANPA-0073 for selective and muscle-sparing weight loss, we may encounter new and unforeseen difficulties. Similarly, any future product candidates we may develop may not be able to progress from preclinical to Phase 1 clinical development. For the foregoing reasons, we cannot be certain that our ongoing and planned clinical studies and preclinical studies will be successful. Any of the foregoing occurrences may harm our business, financial condition and prospects significantly.

***Any difficulties or delays in the commencement or completion, or termination or suspension, of our planned clinical studies could result in increased costs to us, delay or limit our ability to generate revenue and adversely affect our commercial prospects.***

In order to obtain FDA approval to market our product candidates, we must demonstrate the safety and efficacy of our product candidates in humans to the satisfaction of the FDA. To meet these requirements, we will have to conduct adequate and well-controlled clinical studies. In addition, before we can initiate clinical studies for any product candidate, we must submit the results of preclinical studies to the FDA or comparable foreign regulatory authorities along with other information, including information about product candidate chemistry, manufacturing and controls and our proposed clinical trial protocol, as part of an IND or similar regulatory submission, and we are also required to submit comparable applications to foreign regulatory authorities for clinical studies outside of the United States. In July 2024, we submitted an IND to the FDA to support initiation of a Phase 2b study of aleniglipron in chronic weight management and received FDA allowance in August 2024. In the fourth quarter of 2024, we initiated the Phase 2b ACCESS study. We dosed the first patient in the ACCESS II study in the fourth quarter of 2024. Since we have not previously tested these higher doses, we cannot be certain whether they have a favorable safety or tolerability profile.

Clinical testing is expensive, time-consuming and subject to uncertainty. Conducting preclinical studies and clinical studies represents a lengthy, time-consuming and expensive process. The length of time may vary

[**Table of Contents**](#TOC)

substantially according to the type, complexity and novelty of the program, and often can be several years or more per program. Delays associated with programs for which we are directly conducting preclinical studies may cause us to incur additional operating expenses.

Clinical studies may not be conducted as planned or completed on schedule, if at all. For example, in September 2023, we reported that a data collection omission had occurred at a clinical site that impacted the obesity cohort (120 mg dose level) of the Phase 2a study for aleniglipron, where weight was not collected at the final (week 12) visit for 24 of the 40 enrolled participants, and as a result of this data collection omission, we were delayed and reported interim Phase 2a obesity cohort data in December 2023, and topline 12-week obesity data in June 2024.

Events that may prevent successful or timely completion of clinical development include:

● delays in reaching a consensus with applicable regulatory authorities on trial design or implementation;

● delays in obtaining regulatory authorization to commence a clinical trial;

● delays in reaching agreement on acceptable terms with prospective contract research organizations ("CROs"), other vendors, or clinical trial sites, the terms of which can be subject to extensive negotiation and may vary significantly among different vendors and trial sites;

● delays in obtaining approval from one or more institutional review boards ("IRB") refusing to approve, suspending or terminating the trial at an investigational site, precluding enrollment of additional participants, or withdrawing their approval of the trial;

● delays in recruiting suitable patients to participate in our ongoing and planned clinical studies;

● changes to the clinical trial protocol;

● clinical sites deviating from trial protocol such as the data collection omission we experienced at a clinical site as discussed above or dropping out of a trial;

● delays in manufacturing sufficient quantities of our product candidates for use in clinical studies, or delays in sufficiently developing, characterizing or controlling a manufacturing process suitable for clinical studies;

● delays in having patients complete participation in a trial or return for post-treatment follow-up;

● participants choosing an alternative treatment for the indication for which we are developing our product candidates, or participating in competing clinical studies;

● lack of adequate funding to continue a clinical trial;

● occurrence of adverse events ("AEs") or serious adverse events ("SAEs") associated with the product candidate that are viewed to outweigh its potential benefits;

● occurrence of SAEs in clinical studies of the same class of agents conducted by other companies;

● imposition of a temporary or permanent clinical hold by regulatory authorities;

● selection of clinical trial end points that require prolonged periods of clinical observation or analysis of the resulting data;

● clinical studies producing negative or inconclusive results;

● a facility manufacturing our product candidates or any of their components being ordered by the FDA or applicable foreign authorities to temporarily or permanently shut down due to violations of current good manufacturing practice ("cGMP") regulations or other applicable requirements, or contamination or cross-contaminations of product candidates in the manufacturing process;

[**Table of Contents**](#TOC)

● third-party clinical investigators losing the licenses or permits necessary to perform our clinical studies, not performing our clinical studies on our anticipated schedule or consistent with the clinical trial protocol or other regulatory requirements or committing fraud; or

● changes in regulatory requirements, guidance, or feedback from regulatory agencies that require amending or submitting new clinical protocols or otherwise modifying the design of our clinical studies.

We could also encounter delays if a clinical trial is suspended or terminated by us, by the IRBs of the institutions in which such studies are being conducted, by a Data Safety Monitoring Board for such trial or by the FDA or applicable foreign authorities. Such authorities may impose such a suspension or termination due to a number of factors, including failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols, inspection of the clinical trial operations or trial site by the FDA or applicable foreign authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using a drug, changes in governmental regulations or administrative actions or lack of adequate funding to continue the clinical trial. In addition, changes in regulatory requirements and policies may occur, and we may need to amend clinical trial protocols to comply with these changes. Amendments may require us to resubmit our clinical trial protocols to IRBs for reexamination and approval, which may impact the costs, timing or successful completion of a clinical trial.

Further, conducting clinical studies in foreign countries, as we may do for our product candidates, presents additional risks that may delay completion of our clinical studies. These risks include the failure of enrolled patients in foreign countries to adhere to clinical protocols as a result of differences in healthcare services or cultural customs, managing additional administrative burdens associated with foreign regulatory requirements, as well as political, currency exchange and other economic risks relevant to such foreign countries. Investigators and patients may not be able to comply with clinical trial protocols if quarantines impede patient movement or interrupt healthcare services. Similarly, our ability to recruit and retain patients and principal investigators and site staff may be reduced, which in turn could adversely impact our clinical trial operations. Additionally, we may experience interruption of key clinical trial activities, such as clinical trial site monitoring, due to limitations on travel, quarantines or social distancing protocols imposed or recommended by federal or state governments, employers and others in connection with public health concerns. We have faced and may continue to face delays in meeting our anticipated timelines for our ongoing and planned clinical studies. We experienced delays in our patient enrollment and our supply chain as a direct result of COVID-19 on our suppliers' ability to timely manufacture and ship certain supplies such as reagents and other lab consumables and due to the data collection omission at a clinical site as discussed above. These delays have previously impacted and could in the future adversely affect our business, financial condition, results of operations and growth prospects.

Any inability to successfully complete preclinical and clinical development could result in additional costs to us or impair our ability to generate revenue from future product sales and regulatory and commercialization milestones. In addition, if we make manufacturing or formulation changes to our product candidates, we may need to conduct additional testing to bridge our modified product candidate to earlier versions. For example, to facilitate potential commercial-scale manufacturing, we expect to transition from capsule formulations of our product candidates used for early clinical studies to tablet formulations, including the addition of excipients, in later stage clinical studies. While these formulation transitions are common for small molecule drug candidates, we cannot guarantee that we will not encounter delays or unexpected results in bridging studies or implementing necessary changes to the manufacturing process. Clinical trial delays could also shorten any periods during which we may have the exclusive right to commercialize our product candidates, if approved, or allow our competitors to bring comparable products to market before we do, which could impair our ability to successfully commercialize our product candidates and may harm our business, financial condition, results of operations and prospects.

[**Table of Contents**](#TOC)

***Enrollment and retention of patients in clinical studies is an expensive and time-consuming process and could be made more difficult or rendered impossible by multiple factors outside our control, which could adversely affect our business, operating results and prospects.***

Patient enrollment is a significant factor impacting the duration of our clinical studies, along with treatment duration and completion of required follow-up periods. Clinical studies may be prolonged, or we may not be able to initiate or continue clinical studies for our product candidates if we are unable to locate and enroll a sufficient number of eligible patients to participate as required by the FDA or applicable foreign authorities. For certain of our product candidates, including ANPA-0073, the conditions which we may evaluate include rare diseases with limited patient pools from which to draw. In some cases, patient populations for rare diseases are located at specific academic sites focused on such indications, often with multiple competing clinical studies. Potential patients for any planned clinical studies may not be adequately diagnosed or identified with the diseases which we are targeting or may not meet the entry criteria for such studies. We also may encounter difficulties in identifying and enrolling patients with a stage of disease appropriate for our planned clinical studies and monitoring such patients adequately during and after treatment. As noted above, other pharmaceutical companies targeting these same diseases are recruiting clinical trial patients from these patient populations, which may make it more difficult to fully enroll our clinical studies. In addition, the process of finding and diagnosing patients may prove costly.

The eligibility criteria of our clinical studies, once established, may further limit the pool of available trial participants. If the actual number of patients with these diseases is smaller than we anticipate, we may encounter difficulties in enrolling patients in our clinical studies, thereby delaying or preventing development and approval of our product candidates. Even once enrolled we may be unable to retain a sufficient number of patients to complete any of our studies.

The timely completion of clinical studies in accordance with their protocols depends, among other things, on our ability to enroll a sufficient number of patients who remain in the study until its conclusion. We may experience difficulties in patient enrollment or retention in our clinical studies for a variety of reasons. Patient enrollment and retention in clinical studies depends on many factors, including:

● the size and nature of the patient population;

● the severity of the disease under investigation;

● the design of the trial protocol;

● the existing body of safety and efficacy data for the product candidate;

● the number and nature of competing treatments and ongoing clinical studies of competing therapies for the same indication;

● the proximity of patients to clinical sites;

● the eligibility criteria for the trial;

● the ability to recruit clinical trial investigators with the appropriate competencies and experience;

● the ability to adequately monitor patients during a trial, clinicians' and patients' perceptions as to the potential advantages of the product candidate being studied;

● the risk that patients will drop out of a trial before completing all site visits; and

● clinicians' and patients' perceptions as to the potential advantages of the drug being studied in relation to other available therapies.

Furthermore, our efforts to build relationships with patient communities may not succeed, which could result in delays in patient enrollment in our clinical studies. If we encounter any delays in enrolling such additional participants, this may further delay our clinical trial. In addition, any negative results we may report in clinical

[**Table of Contents**](#TOC)

studies of our product candidate may make it difficult or impossible to recruit and retain patients in other clinical studies of that same product candidate. Delays or failures in planned patient enrollment or retention may result in increased costs, program delays or both, which could have a harmful effect on our ability to develop our product candidates, or could render further development impossible. For example, the impact of public health epidemics may delay or prevent patients from enrolling or from receiving treatment in accordance with the protocol and the required timelines, which could delay our clinical studies, or prevent us or our partners from completing our clinical studies at all, and harm our ability to obtain approval for such product candidate. Further, if patients drop out of our clinical studies, miss scheduled doses or follow-up visits, or otherwise fail to follow clinical trial protocols, the integrity of data from our clinical studies may be compromised or not accepted by the FDA or applicable foreign authorities, which would represent a significant setback for the applicable program. In addition, we may rely on CROs and clinical trial sites to ensure proper and timely conduct of our future clinical studies and, while we intend to enter into agreements governing their services, we will be limited in our ability to compel their actual performance. Such delays or failures could adversely affect our business, operating results and prospects.

***Serious adverse events, undesirable side effects or other unexpected properties of our product candidates may be identified during development or after approval, which could lead to the discontinuation of our clinical development programs, refusal by regulatory authorities to approve our product candidates or, if discovered following marketing approval, revocation of marketing authorizations or limitations on the use of our product candidates, any of which would limit the commercial potential of such product candidate.***

During the conduct of clinical studies, patients report changes in their health, including illnesses, injuries and discomforts, to their doctor. Often, it is not possible to determine whether or not the product candidate being studied caused these conditions. Regulatory authorities may draw different conclusions or require additional testing to confirm these determinations, if they occur. In addition, it is possible that as we test our product candidates in larger, longer and more extensive clinical studies with a broader group of patients, or as use of these product candidates becomes more widespread if they receive marketing approval, illnesses, injuries, discomforts and other AEs that were observed in earlier studies, as well as conditions that did not occur or went undetected in previous studies, will be reported by participants. Many times, side effects are only detectable after investigational product candidates are tested in large-scale, Phase 3 studies or, in some cases, after they are made available to patients on a commercial scale after approval. If additional clinical experience indicates that any of our current product candidates and any future product candidates has serious or life-threatening side effects or other side effects that outweigh the potential therapeutic benefit, the development of the product candidate may fail or be delayed, or, if the product candidate has received marketing approval, such approval may be revoked, which would harm our business, prospects, operating results and financial condition. In particular, because we are developing our product candidates for chronic indications, the FDA and applicable foreign authorities will likely require that our product candidates demonstrate a higher level of safety over a longer period of time than would be the case for product candidates intended for short-term use. Moreover, if we elect, or are required, to delay, suspend or terminate any clinical trial of our product candidates, the commercial prospects of our product candidates may be harmed and our ability to generate revenue through their sale may be delayed or eliminated. Any of these occurrences may harm our business, financial condition and prospects significantly.

Moreover, if any of our product candidates are associated with undesirable side effects in clinical studies or have characteristics that are unexpected, we may elect to abandon their development or limit their development to more narrow uses or subpopulations in which the undesirable side effects or other characteristics are less prevalent, less severe or more acceptable from a risk-benefit perspective, which may limit the commercial value for the product candidate if approved. We may also be required to modify our trial plans based on findings in our ongoing clinical studies. In our completed Phase 1 SAD and Phase 1b MAD study of aleniglipron, the following adverse events occurred and were considered probably or possibly related to the study drug: nausea, headache, vomiting, dehydration, decreased appetite, dizziness, and diarrhea. In our completed Phase 2a study of aleniglipron, the following adverse events occurred and were considered probably or possibly related to the study drug: nausea, headache, vomiting, decreased appetite, dyspepsia,

[**Table of Contents**](#TOC)

and diarrhea. In our completed Phase 1 SAD and MAD study of ANPA-0073, the following adverse events occurred and were considered probably or possibly related to the study drug: blood creatine phosphokinase increase, dizziness, electrocardiogram T wave inversion, diarrhea, headache, lethargy, nausea, vomiting, chills, palpitations, and sinus tachycardia. However, further analysis may reveal AEs inconsistent with the safety results observed. Many compounds that initially showed promise in early-stage testing have later been found to cause side effects that prevented further development of the compound. In addition, regulatory authorities may draw different conclusions or require additional testing to confirm these determinations.

In addition, if any of our product candidates receive marketing approval, the FDA could require us to include a black box warning in our label or adopt a risk evaluation and mitigation strategy ("REMS"), to ensure that the benefits outweigh its risks, which may include, among other things, a medication guide outlining the risks of the drug for distribution to patients and a communication plan to health care practitioners. For example, the FDA has required that the product labels of approved drugs targeting GLP-1R include a black box warning related to the risk of thyroid C-cell tumors based on rodent carcinogenicity studies. While we have not yet conducted carcinogenicity studies for aleniglipron, because it also targets GLP-1R, it is possible that absent compelling data to the contrary, the FDA and applicable foreign authorities will similarly require a black box warning for aleniglipron if it is approved for marketing. Furthermore, if we or others later identify undesirable side effects caused by our product candidates, several other potentially significant negative consequences could result, including:

● regulatory authorities may suspend or withdraw approvals of such product candidate;

● regulatory authorities may require additional warnings on the label, including "boxed" warnings, or issue safety alerts, Dear Healthcare Provider letters, press releases or other communications containing warnings or other safety information about the product;

● we may be required to change the way a product candidate is administered or conduct additional clinical studies;

● we could be sued and held liable for harm caused to patients;

● we could be subject to fines, injunctions, or the imposition of criminal or civil penalties;

● we may need to conduct a recall;

● we may be forced to suspend marketing of that product, or decide to remove the product from the marketplace; and

● the product may become less competitive, and our reputation may suffer.

Any of these events could prevent us from achieving or maintaining market acceptance of our product candidates and could significantly harm our business, prospects, financial condition and results of operations.

***As an organization, we have never conducted later-stage clinical studies or submitted an NDA, and may be unable to do so for any of our product candidates.***

We are early in our development efforts for our product candidates, and we will need to successfully complete pivotal clinical studies in order to seek FDA or applicable foreign authority approval to market aleniglipron, ACCG-2671, ANPA-0073, LTSE-2578 and any future product candidates we may develop. Carrying out clinical studies and the submission of NDAs is complicated. We have not conducted any later stage or pivotal clinical studies, have limited experience as a company in preparing, submitting and prosecuting regulatory filings and have not previously submitted an NDA or other applicable foreign regulatory submission for any product candidate. We also plan to conduct a number of clinical studies for multiple product candidates in parallel over the next several years. This may be a difficult process to manage with our limited resources and may divert the attention of management. In addition, we are currently planning for later stage interactions with FDA, and other foreign regulatory agencies; however, we cannot guarantee timely or shift alignment on our clinical trial designs, Phase 3 dose rationale and overall size of the data base needed for any future marketing

[**Table of Contents**](#TOC)

applications. Consequently, we may be unable to successfully and efficiently execute and complete necessary clinical studies in a way that leads to regulatory submission and approval of any of our product candidates. We may require more time and incur greater costs than our competitors and may not succeed in obtaining marketing approvals of product candidates that we develop. Failure to commence or complete, or delays in, our planned clinical studies, could prevent us from or delay us in submitting NDAs for and commercializing our product candidates.

***The marketing approval processes of the FDA and applicable foreign authorities are lengthy, time consuming, expensive and inherently unpredictable, and if we are ultimately unable to obtain marketing approval for our product candidates, our business will be substantially harmed.***

The time required to reach approval by the FDA and applicable foreign authorities is unpredictable but typically takes many years following the commencement of clinical studies and depends upon numerous factors, including the substantial discretion of the regulatory authorities. In addition, approval policies, regulations, or the type and amount of clinical data necessary to gain approval may change during the course of a product candidate's clinical development and may vary among jurisdictions. We have not obtained marketing approval for any product candidate and it is possible that any product candidates we may seek to develop in the future will never obtain marketing approval. Neither we nor any future collaborator is permitted to market any of our product candidates in the United States until we receive FDA marketing approval of an NDA.

Prior to obtaining approval to commercialize a product candidate in the United States or abroad, we or our collaborators must demonstrate with substantial evidence from well-controlled clinical studies, and to the satisfaction of the FDA or applicable foreign authorities, that such product candidates are safe and effective for their intended uses. The number of nonclinical studies and clinical studies that will be required for FDA approval varies depending on the product candidate, the disease or condition that the product candidate is designed to address, and the regulations applicable to any particular product candidate. Results from nonclinical studies and clinical studies can be interpreted in different ways. Even if we believe the nonclinical or clinical data for our product candidates are promising, such data may not be sufficient to support approval by the FDA and other regulatory authorities. The FDA and applicable foreign authorities may also require us to conduct additional preclinical studies or clinical studies for our product candidates either prior to or post-approval, or could object to elements of our clinical development program.

The FDA or applicable foreign authorities can delay, limit or deny approval of our product candidates or require us to conduct additional nonclinical or clinical testing or abandon a program for various reasons, including the following:

● the FDA or applicable foreign authorities may disagree with the design or implementation of our clinical studies;

● we may be unable to demonstrate to the satisfaction of the FDA or applicable foreign authorities that a product candidate is safe and effective for its proposed indication;

● the results of clinical studies may not meet the level of statistical significance required by the FDA or applicable foreign authorities for approval;

● serious and unexpected drug-related side effects experienced by participants in our clinical studies or by individuals using drugs similar to our product candidates;

● we may be unable to demonstrate that a product candidate's clinical and other benefits outweigh its safety risks;

● the FDA or applicable foreign authorities may disagree with our interpretation of data from preclinical studies or clinical studies;

[**Table of Contents**](#TOC)

● the data collected from clinical studies of our product candidates may not be acceptable or sufficient to support the submission of an NDA or other submission or to obtain marketing approval in the United States or elsewhere, and we may be required to conduct additional clinical studies;

● the FDA's or the applicable foreign authority's requirement for additional nonclinical studies or clinical studies;

● the FDA or the applicable foreign authority may disagree regarding the formulation, labeling and/or the specifications of our product candidates;

● the FDA or applicable foreign authorities may fail to approve the manufacturing processes or facilities of third-party manufacturers with which we contract for clinical and commercial supplies; and

● the approval policies or regulations of the FDA or applicable foreign authorities may significantly change in a manner rendering our clinical data insufficient for approval.

Of the large number of products in development, only a small percentage successfully complete the FDA or foreign marketing approval processes and are commercialized. The lengthy approval process as well as the unpredictability of future clinical trial results, may result in our failing to obtain marketing approval to market our product candidates, which would significantly harm our business, results of operations and prospects.

***We may expend our limited resources to pursue a particular product candidate and fail to capitalize on product candidates or indications that may be more profitable or for which there is a greater likelihood of success.***

Because we have limited financial and managerial resources, we focus on specific product candidates, indications and discovery programs. Correctly prioritizing our research and development activities is particularly important for us due to the breadth of potential product candidates and indications that we believe could be pursued using our platform technologies. As a result, we may forgo or delay pursuit of opportunities with other product candidates that could have had greater commercial potential. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities. Our spending on current and future research and development programs and product candidates for specific indications may not yield any commercially viable products. If we do not accurately evaluate the commercial potential or target market for a particular product candidate, we may relinquish valuable rights to that product candidate through future collaborations, licenses and other similar arrangements in cases in which it would have been more advantageous for us to retain sole development and commercialization rights to such product candidate. In addition, in recent years, a number of companies have entered the drug discovery industry utilizing different artificial intelligence ("AI") approaches. The success of other such AI approaches to drug discovery could create more competition for us. We believe that we must continue to invest a significant amount of time and resources in our platform technologies to maintain and improve our competitive position.

***We may not be able to obtain or maintain orphan drug designations or exclusivity for our product candidates, which could limit the potential profitability of our product candidates.***

Regulatory authorities in some jurisdictions, including the United States, may designate drugs for relatively small patient populations as orphan drugs. Under the Orphan Drug Act of 1983, the FDA may designate a drug as an orphan drug if it is a drug intended to treat a rare disease or condition, which is generally defined as a patient population of fewer than 200,000 individuals in the United States, or a patient population of greater than 200,000 individuals in the United States but for which there is no reasonable expectation that the cost of developing the drug will be recovered from sales in the United States alone. In the United States, orphan drug designation entitles a party to financial incentives such as opportunities for grant funding towards clinical trial costs, tax advantages and application fee waivers. After the FDA grants orphan drug designation, the generic identity of the drug and its potential orphan use are disclosed publicly by the FDA. Orphan drug designation, however, neither shortens the development time or regulatory review time of a drug nor gives the drug any advantage in the regulatory review or approval process. Generally, if a drug with an orphan drug designation subsequently receives the first marketing approval for the targeted indication, then the drug is

[**Table of Contents**](#TOC)

entitled to a seven-year period of marketing exclusivity that precludes the applicable regulatory authority from approving another marketing application for the same chemical entity for the same indication for the exclusivity period except in limited situations, such as a showing of clinical superiority to the product with orphan drug exclusivity or where the manufacturer is unable to assure sufficient product quantity. For purposes of small molecule drugs, the FDA defines "same drug" as a drug that contains the same active moiety and is intended for the same use as the drug in question. A designated orphan drug may not receive orphan drug exclusivity if it is approved for a use that is broader than the indication for which it received orphan drug designation.

We intend to pursue orphan drug designation for one or more of our product candidates, as well as for potential other future product candidates. Obtaining orphan drug designations is important to our business strategy; however, obtaining an orphan drug designation can be difficult and we may not be successful in doing so. Even if we were to obtain orphan drug designation for a product candidate, we may not obtain orphan exclusivity and that exclusivity may not effectively protect the drug from the competition of different drugs for the same condition, which could be approved during the exclusivity period. Additionally, after an orphan drug is approved, the FDA could subsequently approve another application for the same drug for the same indication if the FDA concludes that the later drug is shown to be safer, more effective or makes a major contribution to patient care. Orphan drug exclusive marketing rights in the United States also may be lost if the FDA later determines that the request for designation was materially defective or if the manufacturer is unable to assure sufficient quantity of the drug to meet the needs of patients with the rare disease or condition. The failure to obtain an orphan drug designation for any product candidates we may develop, the inability to maintain that designation for the duration of the applicable period, or the inability to obtain or maintain orphan drug exclusivity could reduce our ability to make sufficient sales of the applicable product candidate to balance our expenses incurred to develop it, which would have a negative impact on our operational results and financial condition.

***We have conducted, or plan to conduct, our initial clinical studies for aleniglipron, ANPA-0073, LTSE-2578 and our other product candidates outside of the United States. However, the FDA and other foreign equivalents may not accept data from such studies, in which case our development plans will be delayed, which could materially harm our business.***

We have conducted our initial clinical studies for aleniglipron and ANPA-0073 in Australia, and may conduct our Phase 1 studies for other drug candidates in Australia, China or other foreign countries. The acceptance of study data from clinical studies conducted outside the United States or another jurisdiction by the FDA or applicable foreign authority may be subject to certain conditions or may not be accepted at all. In cases where data from foreign clinical studies are intended to serve as the sole basis for marketing approval in the United States, the FDA will generally not approve the application on the basis of foreign data alone unless (i) the data are applicable to the U.S. population and U.S. medical practice; (ii) the studies were performed by clinical investigators of recognized competence and pursuant to good clinical practices ("GCP") regulations; and (iii) the data may be considered valid without the need for an on-site inspection by the FDA, or if the FDA considers such inspection to be necessary, the FDA is able to validate the data through an on-site inspection or other appropriate means. In addition, even where the foreign study data are not intended to serve as the sole basis for approval, the FDA will not accept the data as support for an application for marketing approval unless the study is well-designed and well-conducted in accordance with GCP requirements and the FDA is able to validate the data from the study through an onsite inspection if deemed necessary. Many foreign regulatory authorities have similar approval requirements. In addition, such foreign studies would be subject to the applicable local laws of the foreign jurisdictions where the studies are conducted. There can be no assurance that the FDA or any applicable foreign authority will accept data from studies conducted outside of the United States or the applicable jurisdiction. If the FDA or any applicable foreign authority does not accept such data, it would result in the need for additional studies, which could be costly and time-consuming, and which may result in current or future product candidates that we may develop not receiving approval for commercialization in the applicable jurisdiction.

[**Table of Contents**](#TOC)

We believe that clinical data generated in Australia and China or other foreign countries will be accepted by the FDA and its foreign equivalents; however, there can be no assurance the FDA or applicable foreign authorities will accept data from any other clinical studies that we may conduct in Australia, China or other foreign countries. If the FDA or applicable foreign authorities do not accept any such data, we would likely be required to conduct additional Phase 1 clinical studies, which would be costly and time consuming, and delay aspects of our development plan, which could harm our business.

Conducting clinical studies outside the United States exposes us to additional risks, including risks associated with:

● additional foreign regulatory requirements;

● foreign exchange fluctuations;

● compliance with foreign manufacturing, customs, shipment and storage requirements;

● cultural differences in medical practice and clinical research; and

● diminished protection of intellectual property in some countries.

***Preliminary, topline and interim data from our clinical studies 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.***

From time to time, we may publicly disclose interim, preliminary or topline data from our clinical studies, which are based on a preliminary analysis of then-available data, and the results and related findings and conclusions are subject to change following a more comprehensive review of the data related to the particular study or trial. We also make assumptions, estimations, calculations and conclusions as part of our analyses of data, and we may not have received or had the opportunity to fully and carefully evaluate all data. As a result, the topline or preliminary results that we report may differ from future results of the same studies, or different conclusions or considerations may qualify such results, once additional data have been received and fully evaluated. Topline and preliminary data also remain subject to audit and verification procedures that may result in the final data being materially different from the topline or preliminary data we previously made public. As a result, topline and preliminary data should be viewed with caution until the final data are available. From time to time, we may also disclose interim data from our clinical studies. Interim data from clinical studies that we may complete are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues and more patient data become available. Adverse differences between topline, preliminary or interim data and final data could significantly harm our business prospects. For example, topline results and the length of the study and sample size may render the results of our prior aleniglipron studies not necessarily indicative of the results for our future clinical studies for aleniglipron and may not be comparable to other weight loss products or product candidates, including other oral selective GLP-1RAs. In addition, given the size of the Phase 2a obesity cohort, the primary efficacy endpoint of weight loss was calculated using LSM and analyzed based on the primary efficacy estimand using a mixed model for repeated measures. This means that we drew on all available data, including data from patients that did not follow-up at 12 weeks. The model estimates how patients with missing data would have responded based on patients who continued the study and had similar baseline characteristics (implicit imputation). Due to the preliminary nature of these results and the length of the study and sample size, these results are not necessarily indicative of the final results for our clinical studies for aleniglipron. If the final data is materially different from the preliminary topline data reported, this could significantly harm our business prospects.

Further, others, including regulatory agencies, may not accept or agree with our assumptions, estimates, calculations, conclusions or analyses or may interpret or weigh the importance of data differently, which could impact the value of the particular program, the approvability or commercialization of the particular product candidate or product and our company in general. In addition, the information we choose to publicly disclose regarding a particular study or clinical trial is based on what is typically extensive information, and you or

[**Table of Contents**](#TOC)

others may not agree with what we determine is the material or otherwise appropriate information to include in our disclosure, and any information we determine not to disclose may ultimately be deemed significant with respect to future decisions, conclusions, views, activities or otherwise regarding a particular product, product candidate or our business. If the topline or preliminary data that we report differ from actual results, or if others, including regulatory authorities, disagree with the conclusions reached, our ability to obtain approval for, and commercialize, our product candidates may be harmed, which could harm our business, operating results, prospects or financial condition.

***Obtaining and maintaining marketing approval of our product candidates in one jurisdiction does not mean that we will be successful in obtaining marketing approval of our product candidates in other jurisdictions.***

Obtaining and maintaining marketing approval of our product candidates in one jurisdiction does not guarantee that we will be able to obtain or maintain marketing approval in any other jurisdiction. For example, even if the FDA grants marketing approval of a product candidate, it does not mean that comparable regulatory authorities in foreign jurisdictions must also approve the manufacturing, marketing and promotion and reimbursement of the product candidate in those countries. However, a failure or delay in obtaining marketing approval in one jurisdiction may negatively impact the marketing approval process in others. Approval procedures vary among jurisdictions and can involve requirements and administrative review periods different from those in the United States, including additional preclinical studies or clinical studies as clinical studies conducted in one jurisdiction may not be accepted by regulatory authorities in other jurisdictions. In many jurisdictions outside the United States, a product candidate must be approved for reimbursement before it can be approved for sale in that jurisdiction. In some cases, the price that we intend to charge for our products is also subject to approval.

Obtaining foreign marketing approvals and establishing and maintaining compliance with foreign regulatory requirements could result in significant delays, difficulties and costs for us and could delay or prevent the introduction of our products in certain countries. If we or any future collaborator fail to comply with the regulatory requirements in international markets or fail to receive applicable marketing approvals, our target market will be reduced and our ability to realize the full market potential of our product candidates will be harmed, which would adversely affect our business, prospects, financial condition, and results of operations.

***International trade policies, including tariffs, sanctions and trade barriers may adversely affect our business, financial condition, results of operations and prospects.***

We operate in a global economy, which includes utilizing third-party suppliers in several countries outside the United States. There is inherent risk, based on the complex relationships among the United States and the countries in which we conduct our business, that political, diplomatic and national security factors can lead to global trade restrictions and changes in trade policies and export regulations that may adversely affect our business and operations. The current international trade and regulatory environment is subject to significant ongoing uncertainty. The U.S. government has recently announced substantial new tariffs affecting a wide range of products and jurisdictions and has indicated an intention to continue developing new trade policies, including with respect to the pharmaceutical industry. In response, certain foreign governments have announced or implemented retaliatory tariffs and other protectionist measures. These developments have created a dynamic and unpredictable trade landscape, which may adversely impact our business, results of operations, financial condition and prospects. The Bureau of Industry and Security, U.S. Department of Commerce, has initiated an investigation to determine whether pharmaceutical ingredients, including finished drug product, manufactured outside the United States pose a national security risk and should be subject to additional tariffs.

We do not own or operate, and currently have no plans to establish, any manufacturing facilities. We currently rely, and expect to continue to rely, on third parties for the manufacture of our product candidates for clinical testing, as well as for manufacture of any products that we may commercialize, if approved. Currently, the active pharmaceutical ingredients ("APIs") and drug product are manufactured in China. We also rely on

[**Table of Contents**](#TOC)

specialized laboratory equipment, supplies, materials and precursor compounds, all or part of which we believe may be ultimately sourced from multiple countries outside the United States, to advance our research and development efforts.

Current or future tariffs will result in increased research and development expenses, including with respect to increased costs associated with APIs and drug product. In addition, such tariffs will increase our supply chain complexity and could also potentially disrupt our existing supply chain. Unlike consumer goods, pharmaceuticals face unique regulatory constraints that make rapid supply chain adjustments particularly difficult and costly. Trade restrictions affecting the import of materials necessary for clinical trials could result in delays to our development timelines. Increased development costs and extended development timelines could place us at a competitive disadvantage compared to companies operating in regions with more favorable trade relationships and could reduce investor confidence, negatively impacting our ability to secure additional financing on favorable terms or at all. In addition, as we advance toward commercialization in the future, tariffs and trade restrictions could hinder our ability to establish cost-effective production capabilities, negatively impacting our growth prospects.

The complexity of announced or future tariffs may also increase the risk that we or our suppliers may be subject to civil or criminal enforcement actions in the United States or foreign jurisdictions related to compliance with trade regulations. Foreign governments may also adopt non-tariff measures, such as procurement preferences or informal disincentives to engage with, purchase from or invest in U.S. entities, which may limit our ability to compete internationally and attract non-U.S. investment, employees, customers and suppliers. Foreign governments may also take other retaliatory actions against U.S. entities, such as decreased intellectual property protection, increased enforcement actions or delays in regulatory approvals, which may result in heightened international legal and operational risks. In addition, the United States and other governments have imposed and may continue to impose additional sanctions, such as trade restrictions or trade barriers, which could restrict us from doing business directly or indirectly in or with certain countries or parties and may impose additional costs and complexity to our business.

Trade disputes, tariffs, restrictions and other political tensions between the United States and other countries may also exacerbate unfavorable macroeconomic conditions including inflationary pressures, foreign exchange volatility, financial market instability, and economic recessions or downturns. The ultimate impact of current or future tariffs and trade restrictions remains uncertain and could materially and adversely affect our business, financial condition, and prospects. While we actively monitor these risks, any prolonged economic downturn, escalation in trade tensions, or deterioration in international perception of U.S.-based companies could materially and adversely affect our business, ability to access the capital markets or other financing sources, results of operations, financial condition and prospects. In addition, trade developments have and may continue to heighten the risks related to the other risk factors described elsewhere in this Quarterly Report.

***Disruptions to the operations of the FDA, the SEC, other U.S. governmental agencies or comparable foreign regulatory authorities caused by funding shortages, leadership changes, staffing cuts or other staffing shortages, along with uncertainty regarding the potential for new initiatives, laws, regulations, policies and guidance affecting our product candidates or other aspects of our business, could materially and adversely affect our business.***

The ability of the FDA or other comparable foreign regulatory authorities to review and approve new products or take action with respect to other regulatory matters can be affected by a variety of factors, including government budget and funding levels, leadership changes, the ability to hire and retain key personnel and accept payment of user fees, the availability of personnel and other resources, changes in statutes, regulations and policies that affect the FDA's or comparable foreign regulatory authorities' ability to perform routine functions, and other business disruptions. Average review times at the FDA and comparable foreign regulatory authorities have fluctuated in recent years as a result. In addition, government funding of the SEC and other government agencies on which our operations may rely, including those that fund research and development activities, is subject to the political process, which is inherently fluid and unpredictable.

[**Table of Contents**](#TOC)

Over the last several years, the U.S. government has shut down several times and certain regulatory agencies, such as the FDA and the SEC, have had to furlough critical FDA, SEC and other government employees and stop critical activities. In addition, there have recently been terminations of large numbers of federal employees at various federal agencies, including the FDA. Changes and cuts in FDA staffing could result in delays in the FDA's responsiveness or in its ability to review IND submissions or applications, issue regulations or guidance, or implement or enforce regulatory requirements in a timely fashion, or at all. On October 1, 2025 the U.S. government shut down and it is uncertain when this shutdown will end. A prolonged government shutdown occurs and/or employee terminations or resignations could significantly impact the ability of the FDA or other federal agencies to timely review and process our regulatory submissions, which could have a material adverse effect on our business. Further, current and future government shutdowns and/or employee terminations or resignations at the SEC could impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations.

There is substantial uncertainty as to whether and how the current administration will seek to modify or revise the requirements and policies of the FDA and other regulatory agencies with jurisdiction over our product candidates and any products for which we obtain approval. This uncertainty could present new challenges as we navigate development and approval of our product candidates. Some of these efforts have manifested to date in the form of personnel cuts and measures that could impact the FDA's ability to hire and retain key personnel, which could result in delays or limitations on our ability to obtain guidance from the FDA on our product candidates in development and obtain the requisite regulatory approvals in the future. There is uncertainty as to whether we will be materially and negatively impacted by governmental orders, regulations, policies or guidance, or disruptions to the normal operations of government agencies.

#### Risks Related to Our Reliance on Third Parties
***We rely on third parties for the manufacture of our product candidates for preclinical and clinical development and expect to continue to do so for the foreseeable future. This reliance on third parties increases the risk that we will not have sufficient quantities of our product candidates or products or such quantities at an acceptable cost, which could delay, prevent or impair our development or commercialization efforts.***

We do not own or operate manufacturing facilities and have no plans to build our own clinical or commercial scale manufacturing capabilities. We rely, and expect to continue to rely, on third parties for the manufacture of our product candidates and related raw materials for preclinical and clinical development, as well as for commercial manufacture if any of our product candidates receive marketing approval. This reliance increases the risk that we will not have sufficient quantities of our product candidates or products, if approved, or such quantities at an acceptable cost or quality, which could delay, prevent or impair our development or commercialization efforts. Our APIs and drug product for our product candidates are currently provided by a supplier, WuXi STA, a subsidiary of WuXi AppTec, and we expect to rely on this supplier for the foreseeable future. Contract manufacturing organizations may become subject to legislation, trade restrictions, sanctions, and other regulatory requirements 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. For example, the House of Representatives of the prior Congress (the 118th Congress) passed the BIOSECURE Act, which proposed prohibiting U.S. government contracts, grants, and loans to entities that use equipment and services from certain named Chinese biotech companies, which included WuXi AppTec and WuXi Biologics and certain of their respective subsidiaries and affiliates, and authorized the U.S. government to include additional Chinese biotechnology companies of concern. This version of the BIOSECURE Act included a grandfathering provision allowing biotechnology equipment and services provided or produced by named biotechnology companies of concern under a contract or agreement entered into before the effective date until January 1, 2032. The BIOSECURE Act did not become law in the 118th Congress. It is unclear whether the current Congress (the 119th Congress) will introduce the BIOSECURE Act or similar legislation in this congressional session and, if so, how the scope, prohibitions, or designated biotechnology companies of concern may differ from the version of the BIOSECURE Act passed by the House in the prior 118th Congress. Any U.S. executive action, legislative action or potential sanctions with China could materially impact entities that work

[**Table of Contents**](#TOC)

with Chinese biotechnology companies. U.S. executive agencies have the ability to designate entities and individuals on various governmental prohibited and restricted parties lists. Depending on the designation, potential consequences can range from a comprehensive prohibition on all transactions or dealings with designated parties, or a limited prohibition on certain types of activities, such as exports and financing activities, with designated parties. Such disruption could have adverse effects on the development of our product candidates. We have contracted with, or are in the process of pursuing contracts with, alternative suppliers or manufacturers outside of China for our APIs and drug product for our product candidates. While we believe that our current manufacturing plan will provide us with alternative sources for such supplies, there is a risk that, if supplies are interrupted, or the quality of ingredients provided by such alternative sources is not to our specification, it would cause delays in our supply chain and increase the cost of manufacturing our drugs, which could materially harm our business.

Furthermore, we do not have complete control over all aspects of the manufacturing process of, and are dependent on, our contract manufacturing partners for compliance with cGMP regulations for manufacturing both active drug substances and finished drug products. Third-party manufacturers may not be able to comply with cGMP regulations or similar regulatory requirements outside of the United States. If our contract manufacturers cannot successfully manufacture material that conforms to our specifications and the strict regulatory requirements of the FDA and others, they will not be able to secure and/or maintain marketing approval for their manufacturing facilities. In addition, we do not have control over the ability of our contract manufacturers to maintain adequate quality control, quality assurance and qualified personnel. If the FDA or an applicable foreign authority does not approve these facilities for the manufacture of our product candidates or if the FDA or applicable foreign authority, withdraws any such approval in the future, we may need to find alternative manufacturing facilities, which would significantly impact our ability to develop, obtain marketing approval for or market our product candidates, if approved. Our failure, or the failure of our third-party manufacturers, to comply with applicable regulations could result in sanctions being imposed on us, including fines, injunctions, civil penalties, delays, suspension or withdrawal of approvals, license revocation, seizures or recalls of product candidates or drugs, operating restrictions and criminal prosecutions, any of which could significantly and adversely affect supplies of our product candidates or drugs and harm our business and results of operations.

***Our current and anticipated future dependence upon others for the manufacture of our product candidates or drugs may adversely affect our future profit margins and our ability to commercialize any product candidates that receive marketing approval on a timely and competitive basis.***

In the event that any of our manufacturers fails to comply with applicable requirements or to perform its obligations to us in relation to quality, timing or otherwise, or if our supply of components or other materials becomes limited or interrupted for other reasons, including due to the impact of future global pandemics, we may be forced to manufacture the materials ourselves, for which we currently do not have the capabilities or resources, or enter into an agreement with another third party, which we may not be able to do on commercially reasonable terms, if at all. In particular, any replacement of our manufacturers could require significant effort and expertise because there may be a limited number of qualified replacements. In some cases, the technical skills or technology required to manufacture our product candidates may be unique or proprietary to the original manufacturer and we may have difficulty transferring such skills or technology to another third party and a feasible alternative may not exist. In addition, certain of our product candidates and our own proprietary methods have never been produced or implemented outside of our company, and we may therefore experience delays to our development programs if and when we attempt to establish new third-party manufacturing arrangements for these product candidates or methods. These factors would increase our reliance on our third-party manufacturers or require us to obtain a license from such manufacturers in order to have another third-party manufacture our product candidates. If we are required to or voluntarily change manufacturers for any reason, we will be required to verify that the new manufacturer maintains facilities and procedures that comply with quality standards and with all applicable regulations and guidelines. We will also need to verify, such as through a manufacturing comparability study, that any product produced by the new manufacturer is equivalent to that produced in a prior facility. The delays associated with the

[**Table of Contents**](#TOC)

verification of a new manufacturer and equivalent product could negatively affect our ability to develop product candidates in a timely manner or within budget.

Our or a third party's failure to execute on our manufacturing requirements on commercially reasonable terms and timelines, if at all, and comply with cGMP requirements could adversely affect our business in a number of ways, including:

● inability to meet our drug specifications and quality requirements consistently;

● delay or inability to procure or expand sufficient manufacturing capacity;

● issues related to scale-up of manufacturing;

● costs and validation of new equipment and facilities required for scale-up;

● failure to comply with cGMP or similar foreign standards;

● inability to negotiate manufacturing agreements with third parties under commercially reasonable terms, if at all;

● reliance on single source manufacturers for drug substances and drug products;

● lack of qualified backup suppliers for those components that are currently purchased from a sole or single source supplier;

● misappropriation of proprietary information, including our trade secrets and know-how;

● the mislabeling of clinical supplies, potentially resulting in the wrong dose amounts being supplied or study drug or placebo not being properly identified;

● clinical supplies not being delivered to clinical sites on time, leading to clinical trial interruptions;

● operations of our third-party manufacturers or suppliers could be disrupted by conditions unrelated to our business or operations, including the bankruptcy of the manufacturer or supplier; and

● carrier disruptions or increased costs that are beyond our control.

In addition, we do not have any long-term commitments or supply agreements with our third-party manufacturers. We may be unable to establish any supply agreements with our third-party manufacturers or do so on acceptable terms, which increases the risk of timely obtaining sufficient quantities of our product candidates or such quantities at an acceptable cost, which may harm our business and results of operations.

***We rely on third parties to conduct, supervise and monitor our discovery research, preclinical studies and clinical studies. We have experienced delays due to actions of third parties in the past and if in the future third parties do not satisfactorily carry out their contractual duties or fail to meet expected deadlines, our development programs may be delayed or subject to increased costs, each of which may have an adverse effect on our business and prospects.***

We do not currently have the ability to independently conduct certain discovery research, preclinical studies and clinical studies for our product candidates. We rely on CROs and clinical trial sites to ensure the proper and timely conduct of our preclinical studies and clinical studies, and we expect to have limited influence over their actual performance. We rely upon CROs to monitor and manage data for our clinical programs, as well as the execution of future nonclinical studies. We expect to control only certain aspects of our CROs' activities. Nevertheless, we will be responsible for ensuring that each of our preclinical studies or clinical studies are conducted in accordance with the applicable protocol, legal, regulatory and scientific standards and our reliance on the CROs does not relieve us of our regulatory responsibilities.

[**Table of Contents**](#TOC)

We and our CROs will be required to comply with the good laboratory practices, and GCPs, which are regulations and guidelines enforced by the FDA and applicable foreign authorities in the form of International Conference on Harmonization guidelines for any of our product candidates that are in preclinical and clinical development. The regulatory authorities enforce GCPs through periodic inspections of trial sponsors, principal investigators and clinical trial sites. Although we will rely on CROs to conduct good laboratory practices-compliant preclinical studies and GCP-compliant clinical studies, we remain responsible for ensuring that each of our good laboratory practices preclinical studies and clinical studies is conducted in accordance with its investigational plan and protocol and applicable laws and regulations, and our reliance on the CROs does not relieve us of our regulatory responsibilities. If we or our CROs fail to comply with GCPs, the clinical data generated in our clinical studies may be deemed unreliable and the FDA or applicable foreign authorities may require us to perform additional clinical studies before approving our marketing applications. For example, in September 2023, we announced that topline data from the obesity cohort of our Phase 2a trial of aleniglipron would be delayed because of a data collection omission by a clinical site, where weight was not collected at the final (week 12) visit for 24 of the 40 enrolled participants. Accordingly, if our CROs fail to comply with these regulations or fail to recruit a sufficient number of participants or ensure the collection of requisite data by clinical sites, we may be required to enroll additional participants or repeat clinical studies, which would delay the marketing approval process.

While we will have agreements governing their activities, our CROs will not be our employees, and we will not control whether or not they devote sufficient time and resources to our future clinical and nonclinical programs. These CROs may also have relationships with other commercial entities, including our competitors, for whom they may also be conducting clinical studies, or other drug development activities which could harm our business. We face the risk of potential unauthorized disclosure or misappropriation of our intellectual property by CROs, which may reduce our trade secret protection and allow our potential competitors to access and exploit our proprietary technology. If our CROs do not successfully carry out their contractual duties or obligations, fail to meet expected deadlines, or if the quality or accuracy of the clinical data they obtain is compromised due to the failure to adhere to our clinical protocols or regulatory requirements or for any other reasons, our clinical studies may be extended, delayed or terminated, and we may not be able to obtain marketing approval for, or successfully commercialize any product candidate that we develop. As a result, our financial results and the commercial prospects for any product candidate that we develop would be harmed, our costs could increase, and our ability to generate revenue could be delayed.

If our relationship with these CROs terminates, we may not be able to enter into arrangements with alternative CROs or do so on commercially reasonable terms. Switching or adding additional CROs involves substantial cost and requires management time and focus. In addition, there is a natural transition period when a new CRO commences work. As a result, delays occur, which can negatively impact our ability to meet our desired clinical development timelines. Though we intend to carefully manage our relationships with our CROs, we may encounter challenges or delays in the future and we cannot assure you that these delays or challenges will not have a negative impact on our business, financial condition and prospects.

[**Table of Contents**](#TOC)

***We have entered into, and may in the future enter into, collaboration agreements and strategic alliances to maximize the potential of our structure-based drug discovery platform and product candidates, and we may not realize the anticipated benefits of such collaborations or alliances. We expect to continue to form collaborations in the future with respect to our product candidates, but may be unable to do so or to realize the potential benefits of such transactions, which may cause us to alter or delay our development and commercialization plans.***

Part of our business strategy is to explore additional collaborations with third parties to further strengthen our platform capabilities and to leverage our platform for external opportunities where partners bring additional disease biology understanding, development and commercial expertise, regional insights or other complementary capabilities. We may therefore form or seek further 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 structure-based drug discovery platform or our product candidates and any future product candidates that we may develop, including in territories outside the United States or for certain indications. These transactions can entail numerous operational and financial risks, including exposure to unknown liabilities, disruption of our business and diversion of our management's time and attention in order to manage a collaboration or develop acquired products, product candidates or technologies, incurrence of substantial debt or dilutive issuances of equity securities to pay transaction consideration or costs, higher than expected collaboration, acquisition or integration costs, write-downs of assets or goodwill or impairment charges, increased amortization expenses, difficulty and cost in facilitating the collaboration or combining the operations and personnel of any acquired business, impairment of relationships with key suppliers, manufacturers or customers of any acquired business due to changes in management and ownership and the inability to retain key employees of any acquired business. As a result, if we enter into acquisition or license agreements or strategic partnerships, we may not be able to realize the benefit of such transactions if we are unable to successfully integrate them with our existing operations and company culture. We also cannot be certain that, following a strategic transaction or license, we will achieve the revenue or other anticipated benefits that led us to enter into the arrangement.

Research and development collaborations are subject to numerous risks, which may include the following:

● collaborators have significant discretion in determining the efforts and resources that they will apply to a collaboration, and may not commit sufficient efforts and resources, or may misapply those efforts and resources;

● collaborators may not pursue development and commercialization of our structure-based drug discovery platform or collaboration product candidates or may elect not to continue or renew development or commercialization programs based on clinical trial results or changes in their strategic focus;

● collaborators may delay, provide insufficient resources to, or modify or stop clinical studies for our structure-based drug discovery platform or collaboration product candidates;

● collaborators could develop or acquire products outside of the collaboration that compete directly or indirectly with our products or product candidates;

● 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;

● disputes may arise between us and a collaborator that cause the delay or termination of the research, development or commercialization of our product 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 and personnel to pursue further development or commercialization of our structure-based drug discovery platform or the applicable product candidates; and

[**Table of Contents**](#TOC)

● collaborators may own or co-own intellectual property covering our products that results from our collaborating with them, and in such cases, we may not have the exclusive right to commercialize such intellectual property.

In addition, we face significant competition in seeking appropriate strategic partners and the negotiation process is time-consuming and complex. We may not be successful in our efforts to establish a strategic partnership or other alternative arrangements for our structure-based drug discovery platform or product candidates because they may be deemed to be at too early of a stage of development for collaborative effort and third parties may not view our product candidates as having the requisite potential to demonstrate safety and efficacy. If and when we collaborate with a third party for development and commercialization of a product candidate, we can expect to relinquish some or all of the control over the future success of that product candidate to the third party. Our ability to reach a definitive agreement for a collaboration will depend, among other things, upon our assessment of the collaborator's resources and expertise, the terms and conditions of the proposed collaboration and the proposed collaborator's evaluation of our technologies, product candidates and market opportunities. The collaborator may also consider alternative product candidates or technologies for similar indications that may be available to collaborate on and whether such a collaboration could be more attractive than the one with us for our product candidate. We may also be restricted under any license agreements from entering into agreements on certain terms or at all with potential collaborators.

As a result of these risks, we may not be able to realize the benefit of our existing collaborations or any future collaborations or licensing agreements we may enter into. In addition, there have been a significant number of recent business combinations among large pharmaceutical and biomedical companies that have resulted in a reduced number of potential future collaborators and changes to the strategies of the combined company. As a result, we may not be able to negotiate collaborations on a timely basis, on acceptable terms, or at all. In addition, we may face regulatory obstacles in completing such transactions. If we are unable to do so, we may have to curtail the development of such product candidate, reduce or delay one or more of our other development programs, delay the potential commercialization or reduce the scope of any planned sales or marketing activities for such product candidate, or increase our expenditures and undertake development, manufacturing or commercialization activities at our own expense. If we elect to increase our expenditures to fund development, manufacturing or commercialization activities on our own, we may need to obtain additional capital, which may not be available to us on acceptable terms or at all. If we do not have sufficient funds, we may not be able to further develop our structure-based drug discovery platform or product candidates or bring them to market and generate revenue.

Additionally, we may sometimes collaborate with academic institutions to accelerate our preclinical research or development under written agreements with these institutions. If collaborations occur, these institutions provide us with an option to negotiate a license to any of the institution's rights in technology resulting from the collaboration. Regardless of such option, we may be unable to negotiate a license within the specified timeframe or under terms that are acceptable to us. If we are unable to do so, the institution may offer the intellectual property rights to other parties, potentially blocking our ability to pursue our program. If we are unable to successfully obtain rights to required third-party intellectual property or to maintain the existing intellectual property rights we have, we may have to abandon development of such program and our business and financial condition could suffer.

Our products require specific constituents to work effectively and efficiently, and rights to those constituents are, and in the future may be, held by others. We may also seek to in-license third-party technologies to enhance our structure-based drug discovery platform. We may be unable to in-license any rights from constituents, methods of use, processes or other third-party intellectual property rights from third parties that we identify. We may fail to obtain any of these licenses at a reasonable cost or on reasonable terms, which could harm our business. Even if we are able to obtain a license, it may be non-exclusive, thereby giving our competitors access to the same technologies licensed to us. In that event, we may be required to expend significant time and resources to develop or license replacement technology in order to establish or maintain our competitive position in the market. Any delays in entering into new collaborations or strategic partnership

[**Table of Contents**](#TOC)

agreements related to our product candidates or our structure-based drug discovery platform could delay the development and commercialization of our product candidates in certain geographies or limit our ability to discover and develop new product candidates, which could harm our business prospects, financial condition, and results of operations.

***Our existing discovery collaborations with Schrödinger (as defined below) are important to our business. If we are unable to maintain these collaborations, or if these collaborations are not successful, our business could be adversely affected.***

In October 2020, Lhotse Bio, Inc. ("Lhotse"), our wholly-owned subsidiary, entered into a collaboration agreement (the "Lhotse-Schrödinger Agreement") with Schrödinger LLC. In November 2023, Aconcagua Bio, Inc. ("Aconcagua"), our wholly-owned subsidiary, entered into a collaboration agreement (the "Aconcagua-Schrödinger Agreement") with Schrödinger, Inc. (together with Schrödinger LLC, "Schrödinger"). Under both agreements, Schrödinger uses its technology platform to perform virtual screens of members of the target class of human integrins, and we and Schrödinger collaborate to facilitate prioritization of targets, perform target validation and analysis, identify leads and perform lead optimization. Schrödinger has granted us an exclusive license to certain intellectual property related to our product candidates discovered under both agreements. See "Related Party Transactions" in Note 9 to our unaudited interim condensed consolidated financial statements in Part I. Item 1 "Financial Statements" in this Quarterly Report for additional information.

Because we currently rely on Schrödinger for a substantial portion of our discovery capabilities, if Schrödinger delays or fails to perform its obligations under the Lhotse-Schrödinger Agreement or Aconcagua-Schrödinger Agreement, disagrees with our interpretation of the terms of the collaborations or our discovery plan or terminates the Lhotse-Schrödinger Agreement or Aconcagua-Schrödinger Agreement, our pipeline of product candidates would be adversely affected. Schrödinger may also fail to properly maintain or defend the intellectual property we have licensed from them, or even infringe upon, our intellectual property rights, leading to the potential invalidation of our intellectual property or subjecting us to litigation or arbitration, any of which would be time-consuming and expensive. Additionally, either party has the right to terminate the collaboration pursuant to the terms of the Lhotse-Schrödinger Agreement or Aconcagua-Schrödinger Agreement, as applicable. If either of our collaborations with Schrödinger is terminated, especially during our discovery phase, the development of our product candidates would be materially delayed or harmed.

***Reliance on third parties requires us to share our trade secrets, which increases the possibility that a competitor will discover them or that our trade secrets will be misappropriated or disclosed.***

Reliance on third parties to manufacture or commercialize our current or any future product candidates, and on collaborations with additional third parties for the development of our current or any future product candidates, requires us to share trade secrets with these third parties. We may also conduct joint research and development programs that may require us to share trade secrets under the terms of our research and development partnerships or similar agreements. We seek to protect our proprietary technology in part by entering into confidentiality agreements and, if applicable, material transfer agreements, services agreements, consulting agreements or other similar agreements with our advisors, employees, third-party contractors and consultants prior to beginning research or disclosing proprietary information. These agreements typically limit the rights of the third parties to use or disclose our confidential information, including our trade secrets. Despite the contractual provisions employed when working with third parties, the need to share trade secrets and other confidential information increases the risk that such trade secrets become known by our competitors, are inadvertently incorporated into the technology of others, or are disclosed or used in violation of these agreements. Given that our proprietary position is based, in part, on our know-how and trade secrets, a competitor's discovery of our trade secrets or other unauthorized use or disclosure could have an adverse effect on our business and results of operations.

In addition, these agreements typically restrict the ability of our advisors, employees, third-party contractors and consultants to publish data potentially relating to our trade secrets. Despite our efforts to protect our trade secrets, our competitors may discover our trade secrets, either through breach of our agreements with third

[**Table of Contents**](#TOC)

parties, independent development or publication of information by any third-party collaborators. A competitor's discovery of our trade secrets could harm our business.

***Confidentiality agreements with employees and third parties may not prevent unauthorized disclosure of trade secrets and other proprietary information.***

In addition to the protection afforded by patents, we seek to rely on trade secret protection and confidentiality agreements to protect proprietary know-how that is not patentable or that we elect not to patent, processes for which patents are difficult to enforce, and any other elements of our product candidates, technology and product discovery and development processes that involve proprietary know-how, information, or technology that is not covered by patents. Any disclosure, either intentional or unintentional, by our employees, the employees of third parties with whom we share our facilities or third-party consultants and vendors that we engage to perform research, clinical studies or manufacturing activities, or misappropriation by third parties (such as through a cybersecurity breach) of our trade secrets or proprietary information could enable competitors to duplicate or surpass our technological achievements, thus eroding our competitive position in our market. Because we expect to rely on third parties in the development and manufacture of our product candidates, we must, at times, share trade secrets with them. Our reliance on third parties requires us to share our trade secrets, which increases the possibility that a competitor will discover them or that our trade secrets will be misappropriated or disclosed.

Trade secrets and confidential information, however, may be difficult to protect. We seek to protect our trade secrets, know-how and confidential information, including our proprietary processes, in part, by entering into confidentiality agreements with our employees, consultants, outside scientific advisors, contractors, and collaborators. With our consultants, contractors, and outside scientific collaborators, these agreements typically include invention assignment obligations. Although we use reasonable efforts to protect our trade secrets, our employees, consultants, outside scientific advisors, contractors, and collaborators might intentionally or inadvertently disclose our trade secret information, including to competitors. In addition, competitors or other third-parties may otherwise gain access to our trade secrets or independently develop substantially equivalent information and techniques. Despite our efforts, any of these parties may breach the agreements and disclose our proprietary information, including our trade secrets, and we may not be able to obtain adequate remedies for such breaches. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret is 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. Furthermore, the laws of some foreign countries do not protect proprietary rights to the same extent or in the same manner as the laws of the United States. As a result, we may encounter significant problems in protecting and defending our intellectual property both in the United States and abroad. If we are unable to prevent unauthorized material disclosure of our intellectual property to third parties, or misappropriation of our intellectual property by third parties, we may not be able to establish or maintain a competitive advantage in our market, which could materially adversely affect our business, operating results, and financial condition.

***The adoption and deployment of AI in our, and any third-party collaborators' operations, and in particular our and any third-party collaborators' R&D efforts to explore new targets and develop effective products, may not be effective and may expose us to risk.***

The industry in which we compete is characterized by rapid technological advancements, frequent introductions of new products and heavy competition. The discovery of new products and targets remain vital to our success and the implementation by us and by any third-party collaborators of AI technologies and processes, including advanced predictive analytics, computational approaches for drug discovery and so-called "generative" AI, has the potential to provide significant benefits in these areas. Use of AI in our efforts may be difficult to deploy successfully due to operational issues inherent in such methods. In particular, the AI algorithms utilize machine learning and predictive analytics which may lead to flawed, biased, and inaccurate results, which could lead to ineffective product or target candidates and exposure to competitive and reputational harm. We face increased competition from other companies that are using AI and related

[**Table of Contents**](#TOC)

methods for drug discovery, some of which have more resources than we do and may have developed more effective methods than we and any third-party collaborators have, which may reduce our and any third-party collaborator's effectiveness in identifying potential targets and attracting additional collaborators to work with us. Even with the successful implementation of AI, we may fail to correctly identify indications and allocate resources efficiently, which could adversely impact our pipeline and ability to compete effectively.

Further, AI presents additional risks and challenges, especially as the use of these technologies becomes more important to our operations over time. Generative AI may be used improperly or inappropriately which could lead to the tainting of our proprietary information and render us unable to qualify for patent protection. Their use by people, including our vendors, employees, suppliers and contractors, with access to our proprietary and confidential information, including trade secrets, may continue to increase and may lead to the release of such information, which may impact our ability to realize the benefit of our intellectual property. Our use of generative AI platforms may lead to novel and urgent cybersecurity risks, which may adversely affect our operations and reputation, as well as the operations of any third-party collaborators. Emerging ethical issues surround the use of AI, and we may be subject to reputational and legal risk if our deployment or use of AI becomes controversial. Regulators could limit our, or any third-party collaborator's ability to develop or implement AI-based technologies as part of measures taken against us or any third-party collaborators in particular or as a consequence of broader legislation, which could have an adverse effect on our or any third-party collaborators' business, results of operations and financial conditions. Several jurisdictions around the globe, including Europe and certain U.S. states, have proposed, enacted, or are considering laws governing the development and use of AI/Machine Learning, such as the EU's AI Act and the Colorado Artificial Intelligence Act. For example, the EU AI Act sets out a risk-based framework, subjecting certain AI technologies to numerous compliance obligations, including transparency, conformity and risk assessment, monitoring and human oversight requirements. Under the EU AI Act, non-compliant companies may be subject to administrative fines of up to 35 million Euros or 7% of a company's total worldwide annual turnover for the preceding financial year, whichever is the higher. Certain of our activities subject us to the EU AI Act and depending on how the EU AI Act is implemented and interpreted, we may have to adapt our business practices, contractual arrangements, and services to comply with such obligations. We expect other jurisdictions will adopt similar laws. Uncertainty in the legal regulatory regime may require significant resources to modify and maintain business practices to comply with U.S. and non-U.S. laws, the nature of which cannot be determined at this time.

#### Risks Related to Commercialization of Our Product Candidates
***Even if we receive regulatory approval for any product candidate, we will be subject to ongoing regulatory obligations and continued regulatory review, which may result in significant additional expense. Additionally, our product candidates, if approved, could be subject to labeling and other restrictions on marketing or withdrawal from the market, and we may be subject to penalties if we fail to comply with regulatory requirements or if we experience unanticipated problems with our product candidates, when and if any of them are approved.***

Even if we obtain any marketing approval for our current or any future product candidates, such approvals will be subject to ongoing regulatory requirements for manufacturing, labeling, packaging, storage, advertising, promotion, sampling, record-keeping and submission of safety and other post-market information. These requirements include submissions of safety and other post-marketing information and reports, registration, as well as on-going compliance with cGMPs and GCPs, for any clinical studies that we may conduct post-approval. Any marketing approvals that we receive for our current or future product candidates may also be subject to a REMS, 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 testing, including Phase 4 studies, and surveillance to monitor the quality, safety and efficacy of the drug.

In addition, drug manufacturers and their facilities are subject to payment of user fees and continual review and periodic inspections by the FDA and other regulatory authorities for compliance with cGMP requirements and adherence to commitments made in the NDA or foreign marketing application. If we or a regulatory

[**Table of Contents**](#TOC)

authority discover previously unknown problems with a drug, such as AEs of unanticipated severity or frequency, or problems with the facility where the drug is manufactured or if a regulatory authority disagrees with the promotion, marketing or labeling of that drug, a regulatory authority may impose restrictions relative to that drug, the manufacturing facility or us, including requesting a recall or requiring withdrawal of the drug from the market or suspension of manufacturing.

If we fail to comply with applicable regulatory requirements following approval of our current or future product candidates, a regulatory authority may, among other things:

● issue an untitled letter or warning letter asserting that we are in violation of the law;

● seek an injunction or impose administrative, civil or criminal penalties or monetary fines;

● suspend or withdraw marketing approval;

● suspend any ongoing clinical studies;

● refuse to approve a pending NDA or NDA supplement, or comparable foreign marketing application (or any supplements thereto) submitted by us or our strategic partners;

● restrict or suspend the marketing or manufacturing of the drug;

● seize or detain the drug or otherwise require the withdrawal of the drug from the market;

● refuse to permit the import or export of product candidates; or

● refuse to allow us to enter into supply contracts, including government contracts.

In addition, if any of our product candidates is approved, our product labeling, advertising and promotion will be subject to regulatory requirements and continuing regulatory review. The FDA strictly regulates the promotional claims that may be made about drug products. In particular, a product may not be promoted for uses that are not approved by the FDA as reflected in the product's approved labeling. If we receive marketing approval for a product candidate, physicians may nevertheless prescribe it to their patients in a manner that is inconsistent with the approved label. If we are found to have promoted such off-label uses, we may become subject to significant liability. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses, and a company that is found to have improperly promoted off-label uses may be subject to significant sanctions. The federal government has levied large civil and criminal fines against companies for alleged improper promotion and has enjoined several companies from engaging in off-label promotion. The government has also required companies to enter into consent decrees and/or imposed permanent injunctions under which specified promotional conduct is changed or curtailed.

The FDA's policies, and those of equivalent foreign regulatory agencies, may change and additional government regulations may be enacted that could cause changes to or delays in the drug review process, or suspend or restrict marketing approval of our product candidates. For example, the U.S. Supreme Court's June 2024 decision in *Loper Bright Enterprises v. Raimondo* overturned the longstanding Chevron doctrine, under which courts were required to give deference to regulatory agencies' reasonable interpretations of ambiguous federal statutes (the "*Loper* decision"). The *Loper* decision could result in additional legal challenges to regulations and decisions issued by federal agencies, including the FDA, on which we rely. Any such legal challenges, if successful, could have a material impact on our business. Additionally, the *Loper* decision may result in increased regulatory uncertainty, inconsistent judicial interpretations, and other impacts to the agency rulemaking process, any of which could adversely impact our business and operations. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action, either in the United States or abroad. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may be subject to enforcement action and we may not achieve or sustain profitability, which would harm our business, financial condition, results of operations and prospects.

***Even if our current or future product candidates receive marketing approval, they may fail to achieve market acceptance by physicians, patients, third-party payors or others in the medical community necessary for commercial success.***

Even if our current or future product candidates receive marketing approval, they may fail to gain sufficient market acceptance by physicians, patients, third-party payors and others in the medical community. If they do not achieve an adequate level of acceptance, we may not generate significant product revenue and may not become profitable. The degree of market acceptance of our current or future product candidates, if approved for commercial sale, will depend on a number of factors, including but not limited to:

● the clinical indications for which the product candidate is approved;

● the efficacy and potential advantages compared to alternative treatments and therapies;

● the timing of market introduction of the product as well as competitive products;

● effectiveness of sales and marketing efforts;

● the strength of our relationships with patient communities;

● the cost of treatment in relation to alternative treatments and therapies, including any similar generic treatments;

● our ability to offer such product for sale at competitive prices;

● the convenience and ease of administration compared to alternative treatments and therapies;

● the willingness of the target patient population to try new therapies and of physicians to prescribe these therapies;

● the availability of third-party coverage and adequate reimbursement;

● the willingness of patients to pay out-of-pocket in the absence of coverage and adequate reimbursement by third-party payors and government authorities;

● the strength of marketing and distribution support;

● the prevalence and severity of any side effects; and

● any restrictions on the use of the product together with other medications.

Our efforts to educate physicians, patients, third-party payors and others in the medical community on the benefits of our product candidates may require significant resources and may never be successful. Such efforts may require more resources than are typically required due to the complexity and uniqueness of our product candidates. Because we expect sales of our product candidates, if approved, to generate substantially all of our revenues for the foreseeable future, the failure of our product candidates, if approved, to find market acceptance would harm our business and could require us to seek additional financing.

***Coverage and adequate reimbursement may not be available for our current or any future product candidates, which could make it difficult for us to sell profitably, if approved.***

Market acceptance and sales of any product candidates that we commercialize, if approved, will depend in part on the extent to which coverage and adequate reimbursement for these drugs and related treatments will be available from third-party payors, including government health administration authorities, managed care organizations and other private health insurers. Third-party payors decide which therapies they will pay for and establish reimbursement levels. Commercial payors often rely upon Medicare coverage policy and payment limitations in setting their own coverage and reimbursement policies. However, decisions regarding the extent of coverage and amount of reimbursement to be provided for any product candidates that we develop will be made on a payor-by-payor basis. One third-party payor's determination to provide coverage

[**Table of Contents**](#TOC)

for a drug does not assure that other payors will also provide coverage, and adequate reimbursement, for the drug. Additionally, a third-party payor's decision to provide coverage for a therapy does not imply that an adequate reimbursement rate will be approved. Each third-party payor determines whether or not it will provide coverage for a therapy, what amount it will pay the manufacturer for the therapy, and on what tier of its formulary it will be placed. The position on a third-party payor's list of covered drugs, or formulary, generally determines the co-payment that a patient will need to make to obtain the therapy and can strongly influence the adoption of such therapy by patients and physicians. Patients who are prescribed treatments for their conditions and providers prescribing such services generally rely on third-party payors to reimburse all or part of the associated healthcare costs. Patients are unlikely to use our drugs unless coverage is provided and reimbursement is adequate to cover a significant portion of the cost of our drugs.

A primary trend in the U.S. healthcare industry and elsewhere is cost containment. Third-party payors have attempted to control costs by limiting coverage and the amount of reimbursement for particular medications. We cannot be sure that coverage and reimbursement will be available for any drug that we commercialize and, if reimbursement is available, what the level of reimbursement will be. Inadequate coverage and reimbursement may impact the demand for, or the price of, any drug for which we obtain marketing approval. If coverage and adequate reimbursement are not available, or are available only to limited levels, we may not be able to successfully commercialize our current and any future product candidates that we develop, which could have an adverse effect on our operating results and our overall financial condition. Further, coverage policies and third-party payor reimbursement rates may change at any time. Therefore, even if favorable coverage and reimbursement status is attained for one or more products for which we receive marketing approval, less favorable coverage policies and reimbursement rates may be implemented in the future.

***We face substantial competition, which may result in others discovering, developing or commercializing products before or more successfully than us.***

The biotechnology and biopharmaceutical industries are characterized by rapidly advancing technologies. Our future success will depend in part on our ability to maintain a competitive position with our structure-based drug discovery platform. If we fail to stay at the forefront of technological change in utilizing our platform to create and develop product candidates, we may be unable to compete effectively. Our competitors may render our approach obsolete by advances in existing technological approaches or the development of new or different approaches, potentially eliminating the advantages in our drug discovery process that we believe we derive from our research approach and platform.

In addition, we face competition with respect to our current product candidates and will face competition with respect to any other product candidates that we may seek to develop or commercialize in the future, from major pharmaceutical companies, specialty pharmaceutical companies and biotechnology companies worldwide. There are a number of large pharmaceutical and biotechnology companies that currently market and sell products or are pursuing the development of product candidates for the treatment of the indications that we are pursuing. Potential competitors also 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.

We are aware of GLP-1R small molecules in development by Eli Lilly, Qilu Regor Therapeutics, AstraZeneca/Eccogene, Terns Pharmaceuticals, Jiangsu Hengrui Medicine, Huadong, Sciwind Biosciences, Ascletis, Gilead, Kallyope, MindRank, vTv Therapeutics, Carmot Therapeutics (acquired by Roche Group in January 2024) and Kailera Therapeutics, formerly Hercules CM Newco (licensed HRS-7535, an oral small molecule GLP-1; HRS-9531 a GLP-1/GIP; and preclinical asset HRS-4729 from Jiangsu Hengrui Medicine). There are currently approved GLP-1R peptides for the treatment of diabetes and obesity marketed by Novo Nordisk, Eli Lilly, AstraZeneca, Sanofi and Kailera Therapeutics, formerly Hercules CM Newco. We are also aware of other GLP-1R plus dual/tri incretin targeting peptides in development by Eli Lilly, Jiangsu Hansoh Pharmaceutical Group, Boehringer Ingelheim, Altimmune, Carmot Therapeutics, Sciwind Biosciences, Novo Nordisk, Viking Therapeutics, Amgen, Merck, Zealand Pharma, D&D Pharmatech, GMAX Biopharma, Jiangsu Hengrui Medicine, BrightGene, Innovent Biologics, PegBio, NeuroBo Pharmaceuticals, Hanmi

[**Table of Contents**](#TOC)

Pharmaceuticals, Progen Holdings, Pep2Tango, Metsera (in September 2025, Pfizer and Metsera announced a definitive agreement under which Pfizer will acquire Metsera), QL Biopharma, Lexaria Bioscience, Sun Pharmaceutical, Gan & Lee, Innogen and Biomed Industries. Additionally, we are aware of APJ receptor targeted product candidates in development for COVID-19 acute respiratory distress syndrome by CohBar, Inc.; IPF, systemic sclerosis interstitial lung disease, and kidney nephrotic syndrome by Apie Therapeutics; and muscle atrophy by BioAge Labs, Inc. Both Amgen and Bristol Myers Squibb ("BMS") have APJ receptor targeted product candidates for heart failure. Furthermore, we are aware of LPA1R targeted product candidates in development for IPF by BMS, Horizon Therapeutics (acquired by Amgen in October 2023) and DJS Antibodies; and myelin restoration and neuroinflammation by Contineum Therapeutics.

Many of our competitors, either alone or with their collaborators, have significantly greater financial, technical, manufacturing, marketing, sales and supply resources or experience than we do. If we successfully obtain approval for any product candidate, we will face competition based on many different factors, including the safety and effectiveness of our products, the timing and scope of marketing approvals for these products, the availability and cost of manufacturing, marketing and sales capabilities, price, reimbursement coverage and patent position. Competing products could present superior treatment alternatives, including by being more effective, safer, more convenient, less expensive or marketed and sold more effectively than any products we may develop. Competitive products may make any products we develop obsolete or noncompetitive before we recover the expense of developing and commercializing our product candidates. If we are unable to compete effectively, our opportunity to generate revenue from the sale of our products we may develop, if approved, could be adversely affected.

Mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even more resources being concentrated among a smaller number of our competitors. Smaller and other early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These third parties compete with us in recruiting and retaining qualified scientific, management and commercial personnel, establishing clinical trial sites and subject registration for clinical studies, as well as in acquiring technologies complementary to, or necessary for, our programs. Any failure to compete effectively could harm our business, financial condition and operating results.

In addition, we and any third-party collaborators are facing increasing competition from companies utilizing AI and other computational approaches for drug discovery. Some of these competitors are involved in drug discovery themselves and/or with partners, and others develop software or as well as other tools utilizing AI which can be used, directly or indirectly, in drug discovery. To the extent these other AI approaches to drug discovery prove to be successful, or more successful, than our and any third-party collaborators' approach, our business, financial condition and operating results could be adversely affected.

***If the market opportunities for any of our product candidates are smaller than we estimate, even assuming approval of a product candidate, our revenue may be adversely affected, and our business may suffer.***

The precise incidence and prevalence for all the conditions we aim to address with our product candidates are unknown. Our projections of both the number of people who have these diseases, as well as the subset of people with these diseases who have the potential to benefit from treatment with our product candidates, are based on our beliefs and estimates. These estimates have been derived from a variety of sources, including scientific literature, surveys of clinics, patient foundations or market research, and may prove to be incorrect. Further, new information may change the estimated incidence or prevalence of these diseases. The total addressable market across all of our product candidates will ultimately depend upon, among other things, the diagnosis criteria included in the final label for each of our product candidates approved for sale for these indications, the availability of alternative treatments and the safety, convenience, cost and efficacy of our product candidates relative to such alternative treatments, acceptance by the medical community and patient access, drug pricing and reimbursement. The number of patients in the United States and other major markets and elsewhere may turn out to be lower than expected, patients may not be otherwise amenable to

[**Table of Contents**](#TOC)

treatment with our products or new patients may become increasingly difficult to identify or gain access to, all of which would adversely affect our results of operations and our business.

***We currently have no marketing and sales organization and have no experience as a company in commercializing products, and we may invest significant resources to develop these capabilities. If we are unable to establish marketing and sales capabilities or enter into agreements with third parties to market and sell our products, we may not be able to generate product revenue.***

We have no internal sales, marketing or distribution capabilities, nor have we as a company commercialized a product. If any of our product candidates ultimately receives marketing approval, we will be required to build a marketing and sales organization with technical expertise and supporting distribution capabilities to commercialize each such product in the markets that we target, which will be expensive and time consuming, or collaborate with third parties that have direct sales forces and established distribution systems, either to augment our own sales force and distribution systems or in lieu of our own sales force and distribution systems. We have no prior experience as a company in the marketing, sale and distribution of biopharmaceutical products and there are significant risks involved in building and managing a sales organization, including our ability to hire, retain and incentivize qualified individuals, generate sufficient sales leads, provide adequate training to sales and marketing personnel and effectively manage a geographically dispersed sales and marketing team. Any failure or delay in the development of our internal sales, marketing and distribution capabilities would adversely impact the commercialization of these products. We may not be able to enter into collaborations or hire consultants or external service providers to assist us in sales, marketing and distribution functions on acceptable financial terms, or at all. In addition, our product revenues and our profitability, if any, may be lower if we rely on third parties for these functions than if we were to market, sell and distribute any products that we develop ourselves. We likely will have little control over such third parties, and any of them may fail to devote the necessary resources and attention to sell and market our products effectively. If we are not successful in commercializing our products, either on our own or through arrangements with one or more third parties, we may not be able to generate any future product revenue and we would incur significant additional losses.

***Our future growth may depend, in part, on our ability to commercialize products in foreign markets, where we would be subject to additional regulatory burdens and other risks and uncertainties.***

Our future growth may depend, in part, on our ability to develop and commercialize our product candidates in foreign markets. We are not permitted to market or promote any of our product candidates before we receive regulatory approval from applicable regulatory authorities in foreign markets, and we may never receive such regulatory approvals for any of our product candidates. To obtain separate regulatory approval in many other countries we must comply with numerous and varying regulatory requirements regarding safety and efficacy and governing, among other things, clinical studies, commercial sales, pricing and distribution of our product candidates. If we obtain regulatory approval of our product candidates and ultimately commercialize our products in foreign markets, we would be subject to additional risks and uncertainties, including:

● different regulatory requirements for approval of drugs in foreign countries;

● reduced protection for intellectual property rights;

● the existence of additional third-party patent rights of potential relevance to our business;

● unexpected changes in tariffs, trade barriers and regulatory requirements;

● economic weakness, including inflation, or political instability in particular foreign economies and markets;

● compliance with tax, employment, immigration and labor laws for employees living or traveling abroad;

● foreign currency fluctuations, which could result in increased operating expenses and reduced revenues, and other obligations incident to doing business in another country;

[**Table of Contents**](#TOC)

● foreign reimbursement, pricing and insurance regimes;

● workforce uncertainty in countries where labor unrest is common;

● production shortages resulting from any events affecting raw material supply or manufacturing capabilities abroad; and

● business interruptions resulting from geopolitical actions, including war and terrorism, or natural disasters including earthquakes, typhoons, floods and fires.

#### Risks Related to Our Business Operations and Industry
***Our operating results may fluctuate significantly, which makes our future operating results difficult to predict and could cause our operating results to fall below expectations or any guidance we may provide.***

Our quarterly and annual operating results may fluctuate significantly, which makes it difficult for us to predict our future operating results. These fluctuations may occur due to a variety of factors, many of which are outside of our control, including, but not limited to:

● the timing, degree of success and cost of, and level of investment in, research, development, regulatory approval and commercialization activities relating to our product candidates, which may change from time to time;

● coverage and reimbursement policies with respect to our product candidates, if approved, and potential future drugs that compete with our products;

● the cost of manufacturing our product candidates, which may vary depending on the quantity of production and the terms of our agreements with third-party manufacturers;

● expenditures that we may incur to acquire, develop or commercialize additional product candidates and technologies;

● the level of demand for any approved products, which may vary significantly;

● future accounting pronouncements or changes in our accounting policies; and

● the timing and success or failure of preclinical studies or clinical studies for our product candidates or any competing product candidates, or any other change in the competitive landscape of our industry, including consolidation among our competitors or partners.

The cumulative effects of these factors could result in large fluctuations and unpredictability in our quarterly and annual operating results. As a result, comparing our operating results on a period-to-period basis may not be meaningful. Investors should not rely on our past results as an indication of our future performance. This variability and unpredictability could also result in our failing to meet the expectations of industry or financial analysts or investors for any period. If our revenue or operating results fall below the expectations of analysts or investors or below any forecasts we may provide to the market, or if the forecasts we provide to the market are below the expectations of analysts or investors, the price of our ADSs could decline substantially. Such a price decline could occur even when we have met any previously publicly stated revenue or earnings guidance we may provide.

***We are highly dependent on the services of our senior management team and if we are not able to retain these members of our management team and recruit and retain additional management, clinical and scientific personnel, our business will be harmed.***

We are highly dependent on our senior management team. The employment agreements we have with these officers do not prevent such persons from terminating their employment with us at any time. The loss of the services of any of these persons could impede the achievement of our research, development and

[**Table of Contents**](#TOC)

commercialization objectives. In addition, we will need to attract, retain and motivate highly qualified additional management, clinical and scientific personnel. If we are not able to retain our management and to attract, on terms acceptable to us, additional qualified personnel necessary for the continued development of our business, we may not be able to sustain our operations or grow.

We may not be able to attract or retain qualified personnel in the future due to the intense competition for qualified personnel among biotechnology, pharmaceutical and other businesses. Many of the other pharmaceutical companies that we compete against for qualified personnel and consultants have greater financial and other resources, different risk profiles and a longer operating history in the industry than we do. They also may provide more diverse opportunities and better chances for career advancement. Some of these characteristics may be more appealing to high-quality candidates and consultants than what we have to offer. If we are unable to attract, retain and motivate high-quality personnel and consultants to accomplish our business objectives, the rate and success at which we can discover and develop product candidates and our business will be limited and we may experience constraints on our development objectives.

Our future performance will also depend, in part, on our ability to successfully integrate newly hired executive officers into our management team and our ability to develop an effective working relationship among senior management. Our failure to integrate these individuals and create effective working relationships among them and other members of management could result in inefficiencies in the development and commercialization of our product candidates, harming future marketing approvals, sales of our product candidates and our results of operations. Additionally, we do not currently maintain "key person" life insurance on the lives of our executives or any of our employees.

***We will need to expand our organization, and we may experience difficulties in managing this growth, which could disrupt our operations.***

As of September 30, 2025, we had 218 full-time employees. As we advance our research and development programs, we may need to further increase the number of our employees and the scope of our operations, particularly in the areas of clinical development, discovery biology, chemistry, manufacturing, general and administrative matters related to being a public company, regulatory affairs and, if any of our product candidates receives marketing approval, sales, marketing and distribution. To manage any future growth, we must:

● identify, recruit, integrate, maintain and motivate additional qualified personnel;

● manage our development efforts effectively, including the initiation and conduct of clinical studies for our product candidates; and

● improve our operational, financial and management controls, reporting systems and procedures.

Our future financial performance and our ability to develop, manufacture and commercialize our product candidates, if approved, will depend, in part, on our ability to effectively manage any future growth, and our management may also have to divert financial and other resources, and a disproportionate amount of its attention away from day-to-day activities, to managing these growth activities.

If we are not able to effectively expand our organization by hiring new employees and expanding our groups of consultants and contractors, we may not be able to successfully implement the tasks necessary to further develop and commercialize our product candidates and, accordingly, may not achieve our research, development and commercialization goals.

[**Table of Contents**](#TOC)

***We conduct certain research and development operations through our Australian wholly-owned subsidiaries. If we lose our ability to operate in Australia, or if any of our subsidiaries are unable to receive the research and development tax credit allowed by Australian regulations, or are required to refund any research and development tax credit previously received or reserve for such credit in our financial statements, our business and results of operations could suffer.***

In 2021, we formed two wholly-owned Australian subsidiaries, Annapurna Bio Pty Limited ("Annapurna AU") and Gasherbrum Bio Pty Limited ("Gasherbrum AU"), to conduct various preclinical and clinical activities for our product and development candidates in Australia. Due to the geographical distance and lack of employees currently in Australia, as well as our lack of experience operating in Australia, we may not be able to efficiently or successfully monitor, develop and commercialize our lead products in Australia, including conducting clinical studies. Furthermore, we have no assurance that the results of any clinical studies that we conduct for our product candidates in Australia will be accepted by the FDA or applicable foreign authorities.

In addition, current Australian tax regulations provide for a refundable research and development tax credit equal to 43.5% of qualified expenditures. Although we have previously claimed a refundable research and development tax credit there is a possibility that we may not be able to claim such credit or we might qualify for a lesser credit. If we lose our ability to operate Annapurna AU or Gasherbrum AU in Australia, or if in the future we are ineligible or unable to receive the research and development tax credit or are required to refund any research and development tax credit previously received or have to reserve for such credit in our financial statements, or if the Australian government significantly reduces or eliminates the tax credit, our business and results of operation may be adversely affected.

***Our relationships with customers, physicians and other healthcare providers, and third-party payors may be subject, directly or indirectly, to federal and state healthcare fraud and abuse laws, false claims laws, other healthcare laws and regulations and health data privacy and security laws and regulations, contractual obligations and self-regulatory schemes. If we are unable to comply, or have not fully complied, with such laws, we could face substantial penalties.***

Healthcare providers and third-party payors in the United States and elsewhere will play a primary role in the recommendation and prescription of any product candidates for which we obtain marketing approval. Our current and future arrangements with healthcare professionals, principal investigators, consultants, customers and third-party payors may subject us to various federal and state fraud and abuse laws and other healthcare laws, including, without limitation, the federal Anti-Kickback Statute, the federal civil and criminal false claims laws and the law commonly referred to as the Physician Payments Sunshine Act and regulations. These laws will impact, among other things, our clinical research, as well as our proposed sales and marketing programs. In addition, we may be subject to health information privacy and security laws by the federal government, the states and other jurisdictions in which we may conduct our business. The laws that may affect our operations include, but are not limited to:

● the federal Anti-Kickback Statute, which prohibits, among other things, persons or entities from 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, in return for the purchase, recommendation, leasing or furnishing of an item or service reimbursable under a federal healthcare program, such as the Medicare and Medicaid programs. This statute has been interpreted to apply to, among other things, arrangements between pharmaceutical manufacturers on the one hand, and prescribers, purchasers and formulary managers on the other. A person or entity does not need to have actual knowledge of this statute or specific intent to violate it in order to have committed a violation;

● federal civil and criminal false claims laws, including, without limitation, the False Claims Act, and civil monetary penalty laws, such as the Civil Monetary Penalties Law, which prohibit, among other things, individuals or entities from knowingly presenting, or causing to be presented, claims for payment or approval from Medicare, Medicaid or other government payors that are false or fraudulent or making

[**Table of Contents**](#TOC)

a false statement to avoid, decrease or conceal an obligation to pay money to the federal government. In addition, the government may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the federal False Claims Act;

● the Health Insurance Portability and Accountability Act of 1996 ("HIPAA"), which created additional federal criminal statutes that prohibit, among other things, a person from knowingly and willfully executing a scheme or making false or fraudulent statements to defraud any healthcare benefit program, regardless of the payor (*e.g.*, public or private). Similar to the federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of this statute or specific intent to violate it in order to have committed a violation;

● HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009 ("HITECH"), and their implementing regulations, which imposes certain requirements relating to the privacy, security and transmission of individually identifiable health information without appropriate authorization by entities subject to the rule, such as health plans, healthcare clearinghouses and certain healthcare providers, known as covered entities, and their respective business associates, individuals or entities that perform certain services on behalf of a covered entity that involves the use or disclosure of individually identifiable health information and their subcontractors that use, disclose or otherwise process individually identifiable health information;

● The Physician Payments Sunshine Act, which requires certain manufacturers of drugs, devices, biologics and medical supplies for which payment is available under Medicare, Medicaid or the Children's Health Insurance Program, with specific exceptions, to report annually to the Centers for Medicare & Medicaid Services ("CMS") information related to: (i) payments or other "transfers of value" made to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors), other healthcare professionals (such as physician assistants and nurse practitioners), and teaching hospitals; and (ii) ownership and investment interests held by physicians and their immediate family members;

● state and foreign law equivalents of each of the above federal laws, state laws that require manufacturers to report information related to payments and other transfers of value to physicians and other healthcare providers or marketing expenditures and/or information regarding drug pricing, state laws that require pharmaceutical companies to comply with the pharmaceutical industry's voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government or to adopt compliance programs as prescribed by state laws and regulations, or that otherwise restrict payments that may be made to healthcare providers, state laws and regulations that require drug manufacturers to file reports relating to drug pricing and marketing information, and state and local laws that require the registration of pharmaceutical sales representatives; and

● state and foreign laws that govern the privacy and security of personal information, including health-related information in some circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts.

Because of the breadth of these laws and the limited statutory exceptions and regulatory safe harbors available, it is possible that some of our business activities, including certain scientific advisory board agreements with physicians who are compensated in the form of ordinary shares or share options in addition to cash consideration, could be subject to challenge under one or more of such laws.

[**Table of Contents**](#TOC)

Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations will involve substantial costs. Any action against us for violation of these laws, even if we successfully defend against it, could cause us to incur significant legal expenses and divert our management's attention from the operation of our business. The shifting compliance environment and the need to build and maintain robust and expandable systems to comply with multiple jurisdictions with different compliance and/or reporting requirements increases the possibility that a healthcare company may run afoul of one or more of the requirements.

If our operations are found to be in violation of any of these laws or any other governmental regulations that apply to us, we may be subject to significant civil, criminal and administrative penalties, damages, fines, disgorgement, imprisonment, exclusion from participation in government funded healthcare programs, such as Medicare and Medicaid, additional reporting requirements and oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws and the curtailment or restructuring of our operations.

***Healthcare legislative reform measures may have a negative impact on our business and results of operations.***

In the United States and some foreign jurisdictions, there have been, and continue to be, several legislative and regulatory changes and proposed changes regarding the healthcare system that could prevent or delay marketing approval of product candidates, restrict or regulate post-approval activities, and affect our ability to profitably sell any product candidates for which we obtain marketing approval.

Among policy makers and payors 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, the pharmaceutical industry has been a particular focus of these efforts and has been significantly affected by major legislative initiatives. In March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act (collectively, the "ACA,") was passed, which substantially changed the way healthcare is financed by both the government and private insurers, and significantly impacts the U.S. pharmaceutical industry.

Since its enactment, there have been judicial, congressional and executive branch challenges and amendments to certain aspects of the ACA. For example, on August 16, 2022, the Inflation Reduction Act of 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 and through a newly established manufacturer discount program. It is possible the ACA will be subject to judicial or congressional challenges and amendments in the future.

On July 4, 2025, the annual reconciliation bill, the OBBBA was signed into law which is expected to reduce Medicaid spending and enrollment by implementing work requirements for some beneficiaries, capping state-directed payments, reducing federal funding, and limiting provider taxes used to fund the program. OBBBA also narrows access to ACA marketplace exchange enrollment and declines to extend the ACA enhanced advanced premium tax credits, set to expire in 2025, which, among other provisions in the law, are anticipated to reduce the number of Americans with health insurance.

[**Table of Contents**](#TOC)

Also, there has been heightened governmental scrutiny recently over the manner in which drug manufacturers set prices for their marketed products, which have resulted in several congressional inquiries, presidential executive orders, and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drug products. For example, the IRA, among other things, (1) directs the U.S. Department of Health and Human Services ("HHS") to negotiate the price of certain high-expenditure, single-source drugs covered under Medicare that have been on the market for at least 7 years (the "Medicare Drug Price Negotiation Program") and (2) 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 reimbursement 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 elected up to fifteen additional products 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. On December 8, 2023, the National Institute of Standards and Technology published for comment a Draft Interagency Guidance Framework for Considering the Exercise of March-In Rights which for the first time includes the price of a product as one factor an agency can use when deciding to exercise march-in rights. While march-in rights have not previously been exercised, it is uncertain if that will continue under the new framework.

Individual states in the United States have also become increasingly active in passing legislation and implementing regulations designed to control pharmaceutical product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. For example, on January 5, 2024, the FDA approved Florida's Section 804 Importation Program ("SIP") proposal to import certain drugs from Canada for specific state healthcare programs. It is unclear how this program will be implemented, including which drugs will be chosen, and whether it will be subject to legal challenges in the United States or Canada. Other states have also submitted SIP proposals that are pending review by the FDA. In addition, regional healthcare authorities and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical products and which suppliers will be included in their prescription drug and other healthcare programs. We expect that additional state and federal healthcare reform measures will be adopted in the future.

The current Trump administration is pursuing policies to reduce regulations and expenditures across government including at HHS, the FDA, CMS and related agencies. For example, on September 30, 2025, the current administration announced the first agreement with a major pharmaceutical company that requires the drug manufacturer to offer, through a direct to consumer platform, U.S. patients and Medicaid programs prescription drug Most-Favored Nation pricing equal to or lower than those paid in other developed nations, with additional mandates for direct-to-patient discounts and repatriation of foreign revenues. Other recent actions, presently directed by executive orders or memoranda from the Office of Management and Budget, may propose policy changes that create additional uncertainty for our business. These actions and proposals include, for example, (1) directives to reduce agency workforce and cut programs; (2) rescinding a Biden administration executive order tasking the Center for Medicare and Medicaid Innovation to consider new payment and healthcare models to limit drug spending; (3) eliminating the Biden administration's executive order that directed HHS to establish an AI task force and develop a strategic plan; (4) directing HHS and other agencies to lower prescription drug costs through a variety of initiatives, including by improving upon the Medicare Drug Price Negotiation Program and establishing Most-Favored-Nation pricing for pharmaceutical products; (5) imposing tariffs of imported pharmaceutical products; (6) directing certain federal agencies to enforce existing law regarding hospital and price plan transparency and by standardizing prices across hospitals and health plans; and (7) as part of the Make America Healthy Again ("MAHA") Commission's recent Strategy Report, working across government agencies to increase enforcement on direct-to-consumer pharmaceutical advertising. These actions and policies may significantly reduce U.S. drug prices, potentially impacting manufacturers' global pricing strategies and profitability, while increasing their operational costs and compliance risks. Additionally, Congress may introduce and ultimately pass health care related legislation

[**Table of Contents**](#TOC)

that could impact the drug approval process and make changes to the Medicare Drug Price Negotiation Program created under the IRA. We expect additional health reform measures may be implemented in the future, particularly given the recent change in administration.

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. We expect that these and other healthcare reform measures that may be adopted in the future, may result in more rigorous coverage criteria and additional downward pressure on the price that we receive for any approved drug. Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability, or commercialize our drugs.

***If we or our third-party manufacturers use hazardous and biological materials in a manner that causes injury or violates applicable law, we may be liable for damages.***

Our research and development activities involve the controlled use of potentially hazardous substances, including chemical and biological materials, by our third-party manufacturers. Our manufacturers are subject to federal, state, and local laws and regulations in the United States and foreign jurisdictions governing the use, manufacture, storage, handling and disposal of medical, radioactive and hazardous materials. Although we believe that our manufacturers' procedures for using, handling, storing and disposing of these materials comply with legally prescribed standards, we cannot completely eliminate the risk of contamination or injury resulting from medical, radioactive or hazardous materials. As a result of any such contamination or injury, we may incur liability or local, city, state or federal authorities may curtail the use of these materials and interrupt our business operations. In the event of an accident, we could be held liable for damages or penalized with fines, and the liability could exceed our resources. We do not have any insurance for liabilities arising from medical radioactive or hazardous materials. Compliance with applicable environmental laws and regulations is expensive, and current or future environmental regulations may impair our research, development, and production efforts, which could harm our business, prospects, financial condition, and results of operations.

***Product liability lawsuits against us could cause us to incur substantial liabilities and could limit commercialization of any product candidate that we may develop.***

We face an inherent risk of product liability exposure related to the testing of our current and any future product candidates in clinical studies and may face an even greater risk if we commercialize any product candidate that we may develop. If we cannot successfully defend ourselves against claims that any such product candidates caused injuries, we could incur substantial liabilities. Regardless of merit or eventual outcome, liability claims may result in:

● decreased demand for any product candidate that we may develop;

● product recalls, withdrawals or labeling, marketing or promotional restrictions;

● loss of revenue;

● substantial monetary awards to trial participants or patients;

● significant time and costs to defend the related litigation;

● a diversion of management's time and our resources;

● withdrawal of clinical trial participants;

● initiation of investigations by regulators;

● the inability to commercialize any product candidate that we may develop;

● injury to our reputation and significant negative media attention; and

[**Table of Contents**](#TOC)

● a decline in our ADS price.

We currently hold approximately $10.0 million in product liability insurance coverage in the aggregate. We may need to increase our insurance coverage as we expand our clinical studies and if we successfully commercialize any product candidate. Insurance coverage is increasingly expensive. We may not be able to obtain or maintain insurance coverage at a reasonable cost or in an amount adequate to satisfy any liability that may arise. Although we will 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 that is in excess of the limits of our insurance coverage. Our insurance policies will also have various exclusions, and we may be subject to a product liability claim for which we have no coverage. We may have to pay any amounts 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.

***If our information technology systems or data, or those of third parties upon which we rely, are or were compromised or experienced significant disruptions of our information technology systems or data security incidents, we could experience adverse consequences including but not limited to significant financial, legal, regulatory, business and reputational harm; litigation; fines and penalties; disruptions of our business operations; loss of revenue or profits; loss of customers or sales; or other adverse consequences.***

We are increasingly dependent on information technology systems and infrastructure, including mobile and third-party, cloud-based technologies, to operate our business. In the ordinary course of our business, we collect, store, process and transmit large amounts of sensitive information, including intellectual property, proprietary business information, personal information and other confidential information. We have also outsourced elements of our operations (including elements of our information technology infrastructure) to third parties, and as a result, we manage a number of third-party vendors who may or could have access to our computer networks or our sensitive information. In addition, many of those third parties in turn subcontract or outsource some of their responsibilities to third parties. While all information technology operations are inherently vulnerable to inadvertent or intentional security breaches, incidents, attacks and exposures, the accessibility and distributed nature of our information technology systems, and the sensitive information stored on or transmitted between those systems, make such systems potentially vulnerable to unintentional or malicious, internal and external exploits of our technology environment, including by organized groups and individuals with a wide range of motives (including, but not limited to, industrial espionage) and expertise, including organized criminal groups, "hacktivists," nation states and others. Further, many of our employees work remotely, which increases our vulnerability to cyberattacks. Cyberattacks are increasing in their frequency, levels of persistence, sophistication and intensity, and are being conducted by organized groups and individuals with a wide range of motives (including, but not limited to, industrial espionage) and expertise, including organized criminal groups, "hacktivists," nation states and others. In addition to the extraction of sensitive information, such attacks could include the deployment of harmful malware, ransomware, supply chain attacks, denial-of-service attacks, social engineering and other means to affect service reliability and threaten the confidentiality, integrity and availability of information.

Threat actors also direct significant disruptions of, or cyber incidents at, our or our third-party vendors' and/or business partners' information technology systems that could adversely affect our business operations and/or result in the loss, misappropriation, and/or unauthorized access, use or disclosure of, or the prevention of access to, sensitive information, which could result in a variety of adverse effects, including financial, legal, regulatory, business and reputational harm to us. In addition, information technology system disruptions, whether from attacks on our technology environment or from computer viruses, natural disasters, terrorism, war and telecommunication and electrical failures, 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 studies could result in delays in our marketing approval efforts and significantly increase our costs to recover or reproduce the data. Additionally, theft of our intellectual property or proprietary business information would require substantial expenditures to remedy. If we or our third-party collaborators,

[**Table of Contents**](#TOC)

consultants, contractors, suppliers, vendors or service providers were to suffer an actual or likely attack or breach, for example, that involves the unauthorized access to or use or disclosure of personal or health information for which we are responsible may require us, we may have to notify consumers, partners, collaborators, government authorities, and the media, and may be subject to investigations, civil penalties, administrative and enforcement actions (including mandatory corrective action or requirements to verify the correctness of database contents), and consuming, distracting and expensive litigation, any of which could result in increased costs to us, and result in significant legal and financial exposure, or other harm to our business and reputation.

We and certain of our service providers have in the past and may in the future be subject to cyberattacks and security incidents. For example, in September 2025 we became aware of a security incident that involved unauthorized access to a SharePoint folder, which contained a single file. Available evidence indicates that the file was not accessed or downloaded. 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. While we have implemented security measures intended to protect our information technology systems and infrastructure, such measures may not successfully prevent service interruptions or security incidents.

We take steps designed to detect, mitigate, and remediate vulnerabilities in our information systems (such as our hardware and/or software, including that of third parties with whom we work). We have not and may not in the future, however, detect and remediate all such vulnerabilities including on a timely basis. Further, we have and may experience delays in developing and deploying remedial measures and patches designed to address identified vulnerabilities.

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.

***Our employees, principal investigators, consultants and commercial partners may engage in misconduct or other improper activities, including non-compliance with regulatory standards and requirements and insider trading.***

We are exposed to the risk of fraud or other misconduct by our employees, principal investigators, consultants and commercial partners. Misconduct by these parties could include intentional failures to comply with FDA regulations or the regulations applicable in other jurisdictions, provide accurate information to the FDA and applicable foreign authorities, comply with healthcare fraud and abuse laws and regulations in the United States and abroad, report financial information or data accurately or disclose unauthorized activities to us. In particular, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent fraud, misconduct, kickbacks, self-dealing and other abusive practices. These laws and regulations restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. Such misconduct also could involve the improper use of information obtained in the course of clinical studies or interactions with the FDA or applicable foreign authorities, which could result in regulatory sanctions and cause serious harm to our reputation. It is not always possible to identify and deter employee misconduct, 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 government 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 negative

[**Table of Contents**](#TOC)

impact on our business, financial condition, results of operations and prospects, including the imposition of significant fines or other sanctions.

***Governments outside the United States tend to impose strict price controls, which may adversely affect our revenues, if any.***

In some countries, the pricing of prescription pharmaceuticals is subject to governmental control. In these countries, pricing negotiations with governmental authorities can take considerable time after the receipt of marketing approval for a product candidate. In addition, there can be considerable pressure by governments and other stakeholders on prices and reimbursement levels, including as part of cost containment measures. Political, economic and regulatory developments may further complicate pricing negotiations, and pricing negotiations may continue after coverage and reimbursement have been obtained. Reference pricing used by various countries and parallel distribution or arbitrage between low-priced and high-priced countries, can further reduce prices. To obtain reimbursement or pricing approval in some countries, we may be required to conduct a clinical trial that compares the cost-effectiveness of our product candidate to other available therapies, which is time-consuming and costly. If coverage and reimbursement of our product candidates are unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels, our business could be harmed, possibly materially.

***We and the third parties with whom we work are subject to stringent and evolving U.S. and foreign laws, regulations, rules, industry standards, contractual obligations, policies and other obligations related to data security and privacy. Our or the third parties with whom we work (including our suppliers) actual or perceived failure to comply with such obligations could lead to government enforcement actions, which could include civil, criminal or administrative penalties, litigation (including class claims) and arbitration demands, fines and penalties, disruptions of our business operations, reputational harm, adverse publicity, and other adverse business consequences, and could negatively affect our operating results and business, financial condition, results of operations, and prospects, and other adverse business consequences and could negatively affect our operating results and business, financial condition, results of operations and prospects.***

In the ordinary course of business, we collect, receive, store, process, generate, use, transfer, disclose, make accessible, protect, secure, dispose of, transmit, and share (collectively, processing) personal data and other sensitive information, including proprietary and confidential business data, trade secrets, intellectual property, data we may collect about trial participants in connection with clinical studies, sensitive third-party data, business plans, transactions, and financial information.

The global data protection landscape is rapidly evolving, and we are or may become subject to or be affected by evolving federal, state and foreign data protection laws and regulations, such as laws and regulations that address privacy and data security. In the United States, numerous federal and state laws and regulations, including federal and state health information privacy laws, state data breach notification laws, and federal and state consumer protection laws, such as Section 5 of the Federal Trade Commission Act, govern the collection, use, disclosure and protection of health information and other personal information and could apply to our operations. These laws and regulations are subject to differing interpretations and may be inconsistent among jurisdictions, and guidance on implementation and compliance practices are often updated or otherwise revised, which adds to the complexity of processing personal information. HIPAA, as amended by HITECH, imposes, among other things, certain standards relating to the privacy, security, transmission and breach reporting of individually identifiable health information. We do not believe that we are currently acting as a covered entity or business associate under HIPAA and thus are not directly subject to its requirements or penalties. However, we may obtain health information from third parties, including research institutions from which we obtain clinical trial data, that are subject to privacy and security requirements under HIPAA. Depending on the facts and circumstances, we could face substantial criminal penalties if we knowingly receive individually identifiable health information from a HIPAA-covered healthcare provider or research institution that has not satisfied HIPAA's requirements for disclosure of individually identifiable health information.

[**Table of Contents**](#TOC)

In the past few years, numerous U.S. states 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, (collectively, "CCPA") applies to personal 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 per intentional violation and allows private litigants affected by certain data breaches to recover significant statutory damages. Although the CCPA exempts some data processed in the context of clinical studies, the CCPA increases compliance costs and potential liability with respect to other personal data we maintain about California residents. 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. While these states, like the CCPA, also exempt some data processed in the context of clinical studies, these developments further complicate compliance efforts, and increase legal risk and compliance costs for us, the third parties upon whom we rely.

Outside the United States, an increasing number of laws, regulations, and industry standards govern data privacy and security. For example, the European Union ("EU") General Data Protection Regulation ("GDPR"), the United Kingdom's ("UK") GDPR, and the Personal Information Protection Act in South Korea, impose strict requirements for processing personal data. Under the EU GDPR, companies may face temporary or definitive bans on data processing and other corrective actions; fines of up to 20 million Euros under the EU GDPR, 17.5 million pounds sterling under the UK GDPR or, in each case, 4% of annual global revenue, whichever is greater; or private litigation related to processing of personal data brought by classes of data subjects or consumer protection organizations authorized at law to represent their interests.

In the ordinary course of business, we transfer personal data from Europe and other jurisdictions to the United States or other countries. Europe and other jurisdictions have enacted laws requiring data to be localized or limiting the transfer of personal data to other countries. Other jurisdictions may adopt similarly stringent interpretations of their data localization and cross-border data transfer laws. Although there are currently various mechanisms that may be used to transfer personal data from the European Economic Area ("EEA") and UK to the United States in compliance with law, such as the EEA and UK's standard contractual clauses, these mechanisms are subject to legal challenges, and there is no assurance that we can satisfy or rely on these measures to lawfully transfer personal data to the United States.

If there is no lawful manner for us to transfer personal data from the EEA, the UK or other jurisdictions to the United States, 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 at significant expense, increased exposure to regulatory actions, substantial fines and penalties, the inability to transfer data and work with partners, vendors and other third parties, and injunctions against our processing or transferring of personal data necessary to operate our business. Additionally, companies that transfer personal data out of the EEA and UK to other jurisdictions, particularly to the United States, are subject to increased scrutiny from regulators, individual litigants, and activist groups. Some European regulators have ordered certain companies to suspend or permanently cease certain transfers out of Europe for allegedly violating the GDPR's cross-border data transfer limitations.

Additionally, the U.S. Department of Justice issued a rule entitled the Preventing Access to U.S. Sensitive Personal Data and Government-Related Data by Countries of Concern or Covered Persons, which places

[**Table of Contents**](#TOC)

additional restriction on certain data transactions involving countries of concern (e.g., China, Russia, Iran) and covered individuals (i.e., individuals and entities located in or controlled by individuals or entities located in those jurisdictions) that may impact certain business activities such as vendor engagements, sale or sharing of data, employment of certain individuals, and investor agreements. Violations of the rule could lead to significant civil and criminal fines and penalties. The rule applies regardless of whether data is anonymized, key-coded, pseudonymized, de-identified or encrypted, which presents particular challenges for companies like ours and may impact our ability to transfer data in connection with certain transactions or agreements.

The Cayman Islands Data Protection Act imposes obligations on data controllers in relation to the processing of personal data, and also introduced rights for data subjects (which may be subject to various exemptions), including, among others: (a) personal data must be processed fairly and on the basis of one of the grounds for processing as set out in the Data Protection Act; (b) personal data must be obtained for a specified lawful purpose; (c) personal data must be adequate, relevant and not excessive in relation to the purpose for which it was processed; (d) personal data must be accurate and, where necessary, kept up to date; (e) personal data must not be kept for longer than is necessary; (f) personal data must be processed in accordance with the rights of the data subject; (g) appropriate technical and organizational security measures must be taken to prevent unauthorized or unlawful processing, accidental loss or destruction of personal data; and (h) the personal data may not be transferred to a country unless that country ensures an adequate level of protection for the rights and freedoms of data subjects.

In recent years, authorities of the PRC have promulgated certain laws and regulations in respect of information security, data collection and privacy protection regulations in the PRC, including the Cybersecurity Law of the PRC, the Provisions on Protection of Personal Information of Telecommunication and Internet Users, the Data Security Law of the PRC which became effective from September 1, 2021, and the Personal Information Protection Law of the PRC ("PIPL") which became effective from November 1, 2021. The PIPL imposes a set of specific obligations on covered businesses in connection with their processing and transfer of personal data and imposes fines of up to RMB 50 million or 5% of the prior year's total annual revenue of the violator. Under the PIPL, in case of any personal information processing, such individual prior consent shall be obtained, unless other circumstances clearly mentioned therein to the contrary. Further, any data processing activities in relation to the sensitive personal information such as biometrics, medical health and personal information of teenagers under fourteen years old are not allowed unless such activities have a specific purpose, are highly necessary and have taken strictly protective measures.

Our employees and personnel use generative AI and/or automated decision-making 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 AI and/or automated decision-making technologies. Our use of this technology could result in additional compliance costs, regulatory investigations and actions, and lawsuits. If we are unable to use AI and/or automated decision-making technologies, it could make our business less efficient and result in competitive disadvantages.

In addition to data privacy and security laws, we contractually are subject to industry standards adopted by industry groups and may become subject to such obligations in the future. We are also bound by contractual obligations related to data privacy and security, and our efforts to comply with such obligations may not be successful. In particular, compliance with U.S. and foreign data protection laws and regulations could require us to take on more onerous obligations in our contracts, increase our costs of legal compliance, restrict our ability to collect, use and disclose data, or in some cases, impact our or our partners' suppliers' ability to operate in certain jurisdictions. Our or our service providers' and vendors' actual or perceived failure to comply with U.S. and foreign data protection laws and regulations could result in threatened or actual government investigations and/or enforcement actions (which could include civil, criminal, and administrative penalties), private litigation and/or adverse publicity and could negatively affect our operating results and business. Moreover, clinical trial subjects about whom we or our potential collaborators obtain information, as well as the providers who share this information with us, may contractually limit our ability to use and disclose the information. Claims that we or our third-party service providers have violated individuals' privacy rights,

[**Table of Contents**](#TOC)

failed to comply with data protection laws, or breached our contractual obligations, even if we are not found liable, could be expensive and time consuming to defend and could result in adverse publicity that could harm our business.

We publish privacy policies, self-certifications, and other documentation regarding our collection, use and disclosure of personal information and/or other confidential information. Although we endeavor to comply with our published policies, certifications, and documentation, we may at times fail to do so or may be perceived to have failed to do so. Moreover, despite our efforts, we may not be successful in achieving compliance if our employees or vendors fail to comply with our published policies, certifications, and documentation. Such failures can subject us to potential international, local, state and federal action if they are found to be deceptive, unfair, or misrepresentative of our actual practices.

***There is tax risk associated with the reporting of cross-border arrangements and activities between us and our subsidiaries.***

We are incorporated under the laws of the Cayman Islands and currently have subsidiaries in Mainland China, Hong Kong, Australia, the Cayman Islands and the United States. If we succeed in growing our business, we expect to conduct increased operations through our subsidiaries in various tax jurisdictions pursuant to transfer pricing arrangements between us and our subsidiaries. If two or more affiliated companies are located in different countries, the tax laws or regulations of each country generally will require that transfer prices be the same as those between unrelated companies dealing at arms' length and that appropriate documentation is maintained to support the transfer prices. While we believe that we operate in compliance with applicable transfer pricing laws and intend to continue to do so, our transfer pricing procedures are not binding on applicable tax authorities.

If tax authorities in any of these countries were to successfully challenge our transfer prices as not reflecting arms' length transactions, they could require us to adjust our transfer prices and thereby reallocate our income to reflect these revised transfer prices, which could result in a higher tax liability to us. In addition, if the country from which the income is reallocated does not agree with the reallocation, both countries could tax the same income, resulting in double taxation. If tax authorities were to allocate income to a higher tax jurisdiction, subject our income to double taxation or assess interest and penalties, it would increase our consolidated tax liability, which could adversely affect our financial condition, results of operations and cash flows.

A tax authority could assert that we are subject to tax in a jurisdiction where we believe we have not established a taxable connection, often referred to as a "permanent establishment" under international tax treaties, and such an assertion, if successful, could increase our expected tax liability in one or more jurisdictions. A tax authority may take the position that material income tax liabilities, interest and penalties are payable by us, in which case, we expect that we might contest such assessment. Contesting such an assessment may be lengthy and costly and if we were unsuccessful in disputing the assessment, the implications could increase our anticipated effective tax rate, where applicable.

***Tax authorities may disagree with our positions and conclusions regarding certain tax positions, resulting in unanticipated costs, taxes or non-realization of expected benefits.***

A tax authority may disagree with tax positions that we have taken, which could result in increased tax liabilities. For example, the U.S. Internal Revenue Service or another tax authority could challenge our allocation of income by tax jurisdiction and the amounts paid between our affiliated companies pursuant to our intercompany arrangements and transfer pricing policies, including amounts paid with respect to our intellectual property development. Similarly, a tax authority could assert that we are subject to tax in a jurisdiction where we believe we have not established a taxable connection, often referred to as a "permanent establishment" under international tax treaties, and such an assertion, if successful, could increase our expected tax liability in one or more jurisdictions. A tax authority may take the position that material income tax liabilities, interest and penalties are payable by us, in which case, we expect that we might contest such

[**Table of Contents**](#TOC)

assessment. Contesting such an assessment may be lengthy and costly, and if we were unsuccessful in disputing the assessment, the implications could increase our anticipated effective tax rate, where applicable.

***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 the United States, The One Big Beautiful Bill Act enacted in 2025, the Inflation Reduction Act enacted in 2022, the Coronavirus Aid, Relief, and Economic Security Act enacted in 2020, and the Tax Cuts and Jobs Act enacted in 2017 made many significant changes to the U.S. tax laws. Outside the U.S., various governments and organizations are increasingly focused on tax reform and other legislative or regulatory action to increase tax revenue, including the Organisation for Economic Co-operation and Development's Base Erosion and Profit Shifting Project ("BEPS 2.0"). These laws or any future tax reform legislation could have a material impact on the value of our deferred tax assets, result in significant one-time charges, and increase our future tax expenses.** 

#### Risks Related to Doing Business in China and Our International Operations
***Changes in the political and economic policies or in relations between China and the United States may affect our business, financial condition, results of operations and the market price of our ADSs.***

Due to our operations in China, our business, results of operations, financial condition and prospects may be influenced to a certain degree by economic, political, legal and social conditions in China or changes in government relations between China and the United States or other governments. The Chinese government may intervene in or influence our operations, which could result in a change in our operations and impact the value of our ADSs. Any economic downturn, whether actual or perceived, further decrease in economic growth rates or an otherwise uncertain economic outlook could affect our business, financial condition and results of operations, as well as the market price of our ADSs. In addition, the global macroeconomic environment is facing challenges. 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, and our business operations in the long term. There is significant uncertainty about the future relationship between the United States and China with respect to trade policies, treaties, government regulations and tariffs. The Chinese government has implemented various measures to encourage economic development and guide the allocation of resources. Some of these measures may benefit the overall Chinese economy, but may have a negative effect on us. Due to our operations in China, any future Chinese, U.S. or other rules and regulations that place restrictions on capital raising or other activities by companies with operations in China could affect our business and results of operations. If the business environment in China deteriorates from the perspective of domestic or international investment, or if relations between China and the United States or other governments deteriorate and geopolitical tensions between China and the United States increase, our business in China and United States, as well as the market price of our ADSs, may also be affected.

[**Table of Contents**](#TOC)

***Changes in U.S. and Chinese regulations may impact our business, our operating results, our ability to raise capital and the market price of our ADSs.***

The U.S. government, including the SEC, has made statements and taken certain actions that led to changes to United States and international relations, and will impact companies with connections to the United States or China, including imposing several rounds of tariffs affecting certain products manufactured in China, imposing certain sanctions and restrictions in relation to China and issuing statements indicating enhanced review of companies with certain operations based in China. It is unknown whether and to what extent new legislation, executive orders, tariffs, laws or regulations will be adopted, or the effect that any such actions would have on companies with significant connections to the United States or to China, our industry or on us. We conduct research activities and have business operations both in the United States and China. Any unfavorable government policies on cross-border relations and/or international trade, including increased scrutiny on companies with certain operations based in China, capital controls or tariffs, may affect the competitive position of our drug products, the hiring of scientists and other research and development personnel, the demand for our drug products, the import or export of raw materials in relation to drug development, our ability to raise capital, the market price of our ADSs or prevent us from selling our drug products in certain countries. Furthermore, the SEC has issued statements primarily focused on companies with certain operations based in China, such as us. For example, on July 30, 2021, Gary Gensler, who was then Chairman of the SEC, issued a Statement on Investor Protection Related to Recent Developments in China, pursuant to which Chairman Gensler stated that he has asked the SEC staff to engage in targeted additional reviews of filings for companies with certain operations based in China. The statement also addressed risks inherent in companies with variable interest entity ("VIE") structures. We do not have a VIE structure and are not in an industry that is subject to foreign ownership limitations by China. However, it is possible that our periodic reports and other filings with the SEC may be subject to enhanced review by the SEC and this additional scrutiny could affect our ability to effectively raise capital in the United States.

In response to the SEC's July 30, 2021 statement, the China Securities Regulatory Commission ("CSRC") announced on August 1, 2021, that "[i]t is our belief that Chinese and U.S. regulators shall continue to enhance communication with the principle of mutual respect and cooperation, and properly address the issues related to the supervision of China-based companies listed in the U.S. so as to form stable policy expectations and create benign rules framework for the market." While the CSRC will continue to collaborate "closely with different stakeholders including investors, companies, and relevant authorities to further promote transparency and certainty of policies and implementing measures," it emphasized that it "has always been open to companies' choices to list their securities on international or domestic markets in compliance with relevant laws and regulations."

If any new legislation, executive orders, tariffs, laws and/or regulations are implemented, if existing trade agreements are renegotiated or if the U.S. or Chinese governments take retaliatory actions due to the recent U.S.-China tension, such changes could have an adverse effect on our business, financial condition and results of operations, our ability to raise capital and the market price of our ADSs.

***Compliance with China's current Data Security Law, Cyber Security Law, Cybersecurity Review Measures, Personal Information Protection Law, regulations and guidelines relating to the multi-level protection scheme on cyber security and any other future laws and regulations may entail significant expenses and could affect our business.***

China has implemented or will implement rules and is considering a number of additional proposals relating to data protection. China's current Data Security Law took effect in September 2021. The Data Security Law provides that the data processing activities must be conducted based on "data classification and hierarchical protection system" for the purpose of data protection and prohibits entities in China from transferring data stored in China to foreign law enforcement agencies or judicial authorities without prior approval by the Chinese government.

Additionally, China's Cyber Security Law, promulgated by the Standing Committee of the National People's Congress ("SCNPC") in November 2016 and came into effect in June 2017, and the Administrative Measures for the Hierarchical Protection of Information Security promulgated by the Ministry of Public Security, National Administration of State Secrets Protection, State Cryptography Administration and other government authority in June 2007, requires companies to take certain organizational, technical and administrative measures and other necessary measures to ensure the security of their networks and data stored on their networks. Specifically, the Cyber Security Law and the Administrative Measures for the Hierarchical Protection of Information Security provides that China adopt a multi-level protection scheme ("MLPS"), under which network operators are required to perform obligations of security protection to ensure that the network is free from interference, disruption or unauthorized access, and prevent network data from being disclosed, stolen or tampered. Under the MLPS, entities operating information systems must have a thorough assessment of the risks and the conditions of their information and network systems to determine the level of the entity's information and network systems. These levels range from the lowest Level 1 to the highest Level 5 pursuant to a series of national standards on the grading and implementation of the classified protection of cyber security. The grading result will determine the set of security protection obligations that entities must comply with. Entities classified as Level 2 or above should report the grade to the relevant government authority for examination and approval.

On July 10, 2021, the Cyberspace Administration of China ("CAC") published a draft revision to the existing Cybersecurity Review Measures for public comment (the "Revised Draft CAC Measures"). On January 4, 2022, together with 12 other Chinese regulatory authorities, the CAC released the final version of the Revised Draft CAC Measures (the "Revised CAC Measures"), which came into effect on February 15, 2022. Pursuant to the Revised CAC Measures, critical information infrastructure operators procuring network products and services, and online platform operators (as opposed to "data processors" in the Revised Draft CAC Measures) carrying out data processing activities which affect or may affect national security, shall conduct a cybersecurity review pursuant to the provisions therein. In addition, online platform operators possessing personal information of more than one million users seeking to be listed on foreign stock markets must apply for a cybersecurity review. On November 14, 2021, the CAC further published the Regulations on Network Data Security Management (Draft for Comment) (the "Draft Management Regulations") for public comment. On September 24, 2024, the State Council released the final version of the Draft Management Regulations (the "Management Regulations"), which came into effect on January 1, 2025. Under the Management Regulations, online data processors refer to individuals and organizations who determine the data processing activities in terms of the purpose and methods at their discretion. The Management Regulations reiterate that online data processors shall be subject to national security review pursuant to relevant provisions if they carry out data processing activities which affect or may affect national security.

[**Table of Contents**](#TOC)

As of the date of this Quarterly Report, we have not received any notice from any Chinese regulatory authority identifying us as a "critical information infrastructure operator," "online platform operator", "online platform service provider" or "online data processor," or requiring us to go through the cybersecurity review procedures pursuant to the Revised CAC Measures and the Management Regulations. Based on our understanding of the Revised CAC Measures and the Management Regulations, we do not expect to become subject to cybersecurity review by the CAC for issuing securities to foreign investors because: (i) the clinical and preclinical data we handle in our business operations, either by its nature or in scale, do not normally trigger significant concerns over PRC national security; and (ii) we have not processed, and do not anticipate to process in the foreseeable future, personal information for more than one million users or persons. However, there remains uncertainty as to how the Revised CAC Measures and the Management Regulations will be interpreted or implemented; for example, neither the Revised CAC Measures nor the Management Regulations provides further clarification or interpretation on the criteria for determining those activities that "affect or may affect national security" and relevant Chinese regulatory authorities may interpret it broadly. Furthermore, there remains uncertainty as to whether the Chinese regulatory authorities may adopt new laws, regulations, rules, or detailed implementation and interpretation in relation, or in addition, to the Revised CAC Measures and the Management Regulations. While we intend to closely monitor the evolving laws and regulations in this area and take all reasonable measures to mitigate compliance risks, we cannot guarantee that our business and operations will not be adversely affected by the potential impact of the Revised CAC Measures, the Management Regulations or other laws and regulations related to privacy, data protection and information security.

Also, the National People's Congress released the Personal Information Protection Law, which became effective on November 1, 2021. The Personal Information Protection Law provides a comprehensive set of data privacy and protection requirements that apply to the processing of personal information and expands data protection compliance obligations to cover the processing of personal information of persons by organizations and individuals in China, and the processing of personal information of persons in China outside of China if such processing is for purposes of providing products and services to, or analyzing and evaluating the behavior of, persons in China. The Personal Information Protection Law also provides that critical information infrastructure operators and personal information processing entities who process personal information meeting a volume threshold set by Chinese cyberspace regulators are also required to store in China personal information generated or collected in China, and to pass a security assessment administered by Chinese cyberspace regulators for any export of such personal information. Lastly, the Personal Information Protection Law contains proposals for significant fines for serious violations of up to RMB 50 million or 5% of annual revenues from the prior year and may also be ordered to suspend any related activity by competent authorities. We do not maintain, nor do we intend to maintain in the future, personally identifiable health information of patients in China.

In addition, certain industry-specific laws and regulations affect the collection and transfer of data in the PRC. The Regulations on the Administration of Human Genetic Resources of the PRC (the "HGR Regulation") was promulgated by the State Council in May 2019 and came into effect in July 2019, and was further revised in May 2024. It stipulates that foreign organizations, individuals, and the entities established or actually controlled by foreign organizations or individuals are forbidden to collect, preserve and export China's human genetic resources. Foreign organizations and the entities established or actually controlled by foreign organizations or individuals may only utilize and be provided with China's human genetic resources after satisfaction of all requirements under the HGR Regulation and other applicable laws, such as (i) China's human genetic resources being utilized only in international cooperation with Chinese scientific research institutions, universities, medical institutions, and enterprises for scientific research and clinical studies after completion of requisite approval or filing formalities with competent governmental authorities, and (ii) China's human genetic resources information being provided after required filing and information backup procedures have been gone through. In October 2020, the SCNPC promulgated the Biosecurity Law of the PRC, which came into effect in April 2021 and was further revised in April 2024. The Biosecurity Law of the PRC reaffirms the regulatory requirements stipulated by the HGR Regulation while potentially increasing the administrative sanctions where China's human genetic resources are collected, preserved, exported or used in international cooperation in violation of applicable laws. In May 2023, the Ministry of Science and Technology published

[**Table of Contents**](#TOC)

the Implementing Rules for the Regulations on the Administration of Human Genetic Resources (the "HGR Implementing Rules") which came into effect in July 2023. The HGR Implementing Rules have, among other things, further clarified the scope of China's human genetic resources information, improved the procedure rules for applicable approval, filing and security review, and refined the provisions with respect to the forbiddance on the collection, preservation and export of China's human genetic resources by foreign organizations, individuals, and the entities established or actually controlled by foreign organizations or individuals. There remain significant uncertainties as to how various provisions of the HGR Regulation and the related laws and regulations may be interpreted and implemented. Given such uncertainty, although we have made great efforts to comply with mandatory requirements of laws and government authorities in this regard, we cannot assure you that we will be deemed at all times in full compliance with the HGR Regulation, the Biosecurity Law of the PRC, the HGR Implementing Rules and other applicable laws in our utilizing of and dealing with China's human genetic resources. As a result, we may be exposed to compliance risks under the HGR Regulation, the Biosecurity Law of the PRC and the HGR Implementing Rules.

***The approval of, filing or other procedures with the CSRC or other Chinese regulatory authorities may be required in connection with issuing securities to foreign investors under Chinese law, and, if required, we cannot predict whether we will be able, or how long it will take us, to obtain such approval or complete such filing or other procedures.***

The Regulations on Mergers and Acquisitions of Domestic Enterprises by Foreign Investors purport to require offshore special purpose vehicles that are controlled by Chinese companies or individuals and that have been formed for the purpose of seeking a public listing on an overseas stock exchange through acquisitions of Chinese domestic companies or assets in exchange for the shares of the offshore special purpose vehicles shall obtain CSRC approval prior to publicly listing their securities on an overseas stock exchange.

On July 6, 2021, the relevant Chinese government authorities published the Opinions on Strictly Cracking Down Illegal Securities Activities in Accordance with the Law. These opinions call for strengthened regulation over illegal securities activities and increased supervision of overseas listings by China-based companies, and propose to take effective measures, such as promoting the construction of relevant regulatory systems to regulate the risks and incidents faced by China-based overseas-listed companies.

[**Table of Contents**](#TOC)

Furthermore, on February 17, 2023, the CSRC promulgated a new set of regulations that consists of the Trial Administrative Measures of Overseas Securities Offering and Listing by Domestic Companies (the "Trial Measures") and five supporting guidelines which came into effect on March 31, 2023 to regulate overseas securities offering and listing activities by domestic companies either in direct or indirect form. According to the Trial Measures, we may be required to submit filings to the CSRC in connection with future issuances of our equity securities to foreign investors. For more details, see Part I. Item 1. "Business—Regulation—Other Significant Chinese Regulation Affecting Our Business Activities in China" of our Annual Report on Form 10-K for the year ended December 31, 2024.

As of the date of this Quarterly Report, we have not received any inquiry, notice, warning or sanction regarding obtaining approval, completing filings or other procedures in connection with our previous issuances of securities to foreign investors from the CSRC or any other Chinese regulatory authorities that have jurisdiction over our operations. Based on the above and our understanding of the newly issued Trial Measures and the supporting guidelines, after they came into effect on March 31, 2023, we would not at once be required to submit an application to the CSRC for our previous issuances of securities to foreign investors, but if we intend to make any subsequent securities offering in the same overseas market which are determined as indirect overseas offering and listing by a domestic company under the Trial Measures, we may be required to submit filing with the CSRC within three working days after such subsequent securities offering is completed. However, there remains uncertainty as to the interpretation and implementation of regulatory requirements related to overseas securities offerings and other capital markets activities, and we cannot assure you that the relevant Chinese regulatory authorities, including the CSRC, would reach the same conclusion as us. If it is determined in the future that the approval of, filing or other procedure is required with the CSRC or any other regulatory authority for our previous issuances of securities to foreign investors, or if we are required to complete relevant procedures for our subsequent securities offering in the same overseas market, it is uncertain whether we will be able and how long it will take for us to obtain the approval or complete the filing or other procedure or obtain a waiver for such procedures, despite our best efforts. If we, for any reason, are unable to obtain or complete, or experience significant delays in obtaining or completing, the requisite relevant approval(s), filing(s) or other procedure(s), the regulatory authorities may impose fines and penalties on our operations in China, limit our operating privileges in China, revoke our business licenses, delay or restrict the repatriation of the proceeds from securities offerings into China or take other actions that could have an adverse effect on our business, financial condition, results of operations and prospects, as well as the trading price of the ADSs. Any uncertainties and/or negative publicity regarding the aforementioned approval(s), filing or other procedure(s), the interpretation and implementation of existing laws and regulations, or any further laws, regulations or interpretations that may be released and enacted in the future could have a material adverse effect on the trading price of the ADSs.

***Pharmaceutical companies operating in China are required to comply with extensive regulations and hold a number of permits and licenses to carry on their business. Our ability to obtain and maintain these regulatory approvals is uncertain, and future government regulation may place additional burdens on our current and planned operations in China.***

The pharmaceutical industry in China is subject to extensive government regulation and supervision. The regulatory framework addresses all aspects of operating in the pharmaceutical industry, including product development activities, clinical studies, registration, production, distribution, packaging, labeling, storage and shipment, advertising, licensing and post-approval pharmacovigilance certification requirements and procedures, periodic renewal and reassessment processes, data security and data privacy protection requirements and compliance and environmental protection. In particular, we are subject to many of these laws and regulations because our wholly-owned subsidiary, Basecamp Bio, through which we conduct our technology development and early discovery activities, operates primarily in China. Violation of applicable laws and regulations may materially and adversely affect our business. The regulatory framework governing the pharmaceutical industry in China is subject to change and amendment from time to time. Any such change or amendment could materially and adversely impact our business, financial condition and prospects. The Chinese government has introduced various reforms to the Chinese healthcare system in recent years and may continue to do so, with an overall objective to expand basic medical insurance coverage and

[**Table of Contents**](#TOC)

improve the quality and reliability of healthcare services. The specific regulatory changes under the various reform initiatives remain uncertain. The implementing measures to be issued may not be sufficiently effective to achieve the stated goals, and as a result, we may not be able to benefit from such reform to the extent we expect, if at all. Moreover, the various reform initiatives could give rise to regulatory developments, such as more burdensome administrative procedures, which may have an adverse effect on our business and prospects.

***As a company with operations and business relationships outside of the United States, our business is subject to economic, political, regulatory and other risks associated with international operations.***

As a company with operations in China, our business is subject to risks associated with conducting business outside the United States. In addition to our technology development and early discovery activities through Basecamp Bio in China, substantially all of our suppliers and clinical trial relationships are located outside the United States. Accordingly, our future results could be harmed by a variety of factors, including:

● economic weakness, including inflation, or political instability in particular non-U.S. economies and markets;

● differing and changing regulatory requirements for product approvals;

● differing jurisdictions could present different issues for securing, maintaining or obtaining freedom to operate in such jurisdictions;

● potentially reduced protection for intellectual property rights;

● difficulties in compliance with different, complex and changing laws, regulations and court systems of multiple jurisdictions and compliance with a wide variety of foreign laws, treaties and regulations;

● changes in non-U.S. regulations and customs, tariffs and trade barriers;

● changes in non-U.S. currency exchange rates of the RMB;

● increasing geopolitical tensions between the U.S. and China and changes in a specific country's or region's political or economic environment especially with respect to a particular country's treatment of or stance towards other countries;

● trade protection measures, import or export licensing requirements or other restrictive actions by governments;

● differing reimbursement regimes and price controls in certain non-U.S. markets;

● negative consequences from changes in tax laws;

● compliance with tax, employment, immigration and labor laws for employees living or traveling abroad;

● variable tax treatment in different jurisdictions of options granted under our equity incentive plans;

● workforce uncertainty in countries where labor unrest is more common than in the United States; and

● business interruptions resulting from geo-political actions, including war and terrorism, health epidemics, or natural disasters including earthquakes, typhoons, floods and fires.

***If we fail to comply with Chinese 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 are subject to numerous environmental, health and safety laws and regulations, including those governing laboratory procedures, fire safety and the handling, use, storage, treatment and disposal of hazardous materials and wastes. Our technology development and early discovery operations primarily occur in China

[**Table of Contents**](#TOC)

and involve the use of hazardous materials, including chemical materials. Our operations also produce hazardous waste products. We are therefore subject to Chinese laws and regulations concerning the discharge of wastewater, gaseous waste and solid waste during our processes, including those relating to product development. We engage competent third-party contractors for the transfer and disposal of these materials and wastes. Despite our efforts to comply fully with environmental and safety regulations, any violation of these regulations may result in substantial fines, criminal sanctions, revocations of operating permits, the shutdown of our facilities and the incurrence of obligations to take corrective measures. We cannot completely eliminate the risk of contamination or injury from these materials and wastes. In the event of contamination or injury resulting from the use or discharge 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, administrative or criminal fines and penalties.

Although we maintain workers' compensation insurance to cover costs and expenses incurred due to on-the-job injuries to our employees and public liability insurance to cover costs and expenses that may be incurred if third parties are injured on our property, such insurance may not provide adequate coverage against potential liabilities. Furthermore, the Chinese government may take steps towards the adoption of more stringent environmental regulations, and, due to the possibility of unanticipated regulatory or other developments, the amount and timing of future environmental expenditures may vary substantially from those currently anticipated. If there is any unanticipated change in the environmental regulations, our third-party manufacturers and other service providers may incur substantial capital expenditures to install, replace, upgrade or supplement their manufacturing facilities and equipment or make operational changes to limit any adverse impact or potential adverse impact on the environment in order to comply with new environmental protection laws and regulations. If such costs become prohibitively expensive, we may be forced to cease certain aspects of our business operations and our business could be materially adversely affected.

***Development in the Chinese legal system could materially and adversely affect us.***

Chinese laws and regulations govern our operations in China and 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. As the laws and regulations are relatively new and the PRC legal system continues to evolve, there may be room for discretion in the implementation of these laws and regulations. And as these laws and regulations are evolving in response to changing economic and other conditions, factors related to the application and implementation of these laws and regulations may affect our business and results of operations.

***We may be exposed to liabilities under the U.S. Foreign Corrupt Practices Act (the "FCPA"), U.S. domestic bribery laws, and similar anti-corruption and anti-bribery laws of China and other countries in which we operate, as well as U.S. and certain foreign export controls, trade sanctions and import laws and regulations. Compliance with these legal requirements could limit our ability to compete in foreign markets and any determination that we have violated these laws could have a material adverse effect on our business or our reputation.***

Our operations are subject to the FCPA, U.S. domestic bribery laws, and similar anti-bribery or anti-corruption laws, regulations or rules of China and other countries in which we operate. The FCPA and these other laws generally prohibit us, our officers, and our employees and intermediaries from, directly or indirectly, offering, authorizing or making improper payments to U.S. and non-U.S. government officials for the purpose of obtaining or retaining business or other advantage. We may engage third parties for clinical studies outside of the United States, to sell our products abroad once we enter a commercialization phase, 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. As our business expands, the applicability of the FCPA and other anti-bribery laws to our operations will increase. If our procedures and controls to monitor anti-bribery compliance fail to protect us from reckless or criminal acts committed by our employees or agents or if we, or our employees, agents, contractors or other collaborators, fail to comply with applicable anti-bribery laws, our

[**Table of Contents**](#TOC)

reputation could be harmed and we could incur criminal or civil penalties, other sanctions and/or significant expenses, which could have a material adverse effect on our business, including our financial condition, results of operations, cash flows and prospects.

In addition, our products may be subject to U.S. and foreign export controls, trade sanctions and import laws and regulations. Governmental regulation of the import or export of our products, or our failure to obtain any required import or export authorization for our products, when applicable, could harm our international or domestic sales and adversely affect our revenue. Compliance with applicable regulatory requirements regarding the export of our products may create delays in the introduction of our products in international markets or, in some cases, prevent the export of our products to some countries altogether. Furthermore, U.S. export control laws and economic sanctions prohibit the shipment of certain products and services to countries, governments and persons targeted by U.S. sanctions. If we fail to comply with export and import regulations and such economic sanctions, penalties could be imposed, including fines and/or denial of certain export privileges. Moreover, any new export or import restrictions, new legislation or shifting approaches in the enforcement or scope of existing regulations, or in the countries, persons or products targeted by such regulations, could result in decreased use of our products by, or in our decreased ability to export our products to, existing or potential customers with international operations. Any decreased use of our products or limitation on our ability to export or sell our products would likely adversely affect our business.

***Regulatory Requirements on currency exchange may limit our ability to receive and use effectively financing in foreign currencies.***

Our Chinese subsidiaries' ability to obtain currency exchange is subject to certain foreign exchange regulations and, in the case of transactions under the capital account, requires the approval of and/or registration with Chinese government authorities, including the State Administration of Foreign Exchange ("SAFE"). In particular, if we finance our Chinese subsidiaries by means of foreign debt from us or other foreign lenders, the amount is not allowed to, among other things, exceed the statutory limits and such loans must be registered with the local branch of SAFE. If we finance our Chinese subsidiaries by means of additional capital contributions, these capital contributions are subject to registration with the State Administration for Market Regulation or its local branch, reporting of foreign investment information with the Ministry of Commerce of the People's Republic of China, or its local branch or registration with other governmental authorities in China.

In light of the various requirements imposed by Chinese regulations on loans to, and direct investment in, China-based entities by offshore holding companies, we cannot assure you that we will be able to complete the necessary government requirements or obtain the necessary government approvals on a timely basis, if at all, with respect to future loans or capital contributions by us to our Chinese subsidiaries. If we fail to adhere to such requirements or obtain such approval, our ability to capitalize or otherwise fund our Chinese operations, including our technology development and early discovery activities through Basecamp Bio, may be negatively affected, which could materially and adversely affect our ability to fund and expand our business.

***Chinese regulations relating to the establishment of offshore special purpose companies by residents in China may subject our China resident beneficial owners or our wholly foreign-owned subsidiaries in China to liability or penalties, limit our ability to inject capital into these subsidiaries, limit these subsidiaries' ability to increase their registered capital or distribute profits to us, or may otherwise adversely affect us.***

In 2014, SAFE promulgated the SAFE Circular 37, which requires residents of China to register with local branches of SAFE in connection with their direct establishment or indirect control of an offshore entity, for the purpose of overseas investment and financing, with such residents' legally owned assets or equity interests in domestic enterprises or offshore assets or interests, referred to in SAFE Circular 37 as a "special purpose vehicle." The term "control" under SAFE Circular 37 is broadly defined as the operation rights, beneficiary rights or decision-making rights acquired by residents of China in the offshore special purpose vehicles or

[**Table of Contents**](#TOC)

Chinese companies by such means as acquisition, trust, proxy, voting rights, repurchase, convertible bonds or other arrangements. SAFE Circular 37 further requires amendment to the registration in the event of any changes with respect to the basic information of or any significant changes with respect to the special purpose vehicle, such as an increase or decrease of capital contributed by China residents, share transfer or exchange, merger, division or other material events. If the shareholders of the offshore holding company who are residents of China do not complete their registration with the local SAFE branches, the Chinese subsidiaries may be prohibited from making distributions of profits and proceeds from any reduction in capital, share transfer or liquidation to the offshore parent company and from carrying out subsequent cross-border foreign exchange activities, and the offshore parent company may be restricted in its ability to contribute additional capital into its Chinese subsidiaries. Moreover, failure to comply with the SAFE registration and amendment requirements described above could result in liability under Chinese law for evasion of applicable foreign exchange restrictions.

Certain residents of China may hold direct or indirect interests in our company, and we will request residents of China who we know hold direct or indirect interests in our company, if any, to make the necessary applications, filings and amendments as required under SAFE Circular 37 and other related rules. However, we may not at all times be fully aware or informed of the identities of our shareholders or beneficial owners that are required to make such registrations, and we cannot provide any assurance that these residents will comply with our requests to make or obtain any applicable registrations or comply with other requirements under SAFE Circular 37 or other related rules. The failure or inability of our China resident shareholders to comply with the registration procedures set forth in these regulations may subject us to fines or legal sanctions, restrictions on our cross-border investment activities or those of our China subsidiaries and limitations on the ability of our wholly foreign-owned subsidiaries in China to distribute dividends or the proceeds from any reduction in capital, share transfer or liquidation to us, and we may also be prohibited from injecting additional capital into these subsidiaries. Moreover, failure to comply with the various foreign exchange registration requirements described above could result in liability under Chinese law for circumventing applicable foreign exchange restrictions. As a result, our business operations and our ability to make distributions to you could be materially and adversely affected.

***If we are classified as a China resident enterprise for China income tax purposes, such classification could result in unfavorable tax consequences to us and our non-Chinese shareholders or ADS holders.***

The Enterprise Income Tax Law of the People's Republic of China (the "EIT Law"), which was promulgated in March 2007, became effective in January 2008 and was amended in February 2017 and December 2018, and the Regulation on the Implementation of the EIT Law, effective as of January 1, 2008 and as amended in April 2019 and January 2025, define the term "de facto management bodies" as "bodies that substantially carry out comprehensive management and control on the business operation, personnel, accounts and assets of enterprises." Under the EIT Law, an enterprise incorporated outside of China whose "de facto management bodies" are located in China may be considered a "resident enterprise" and will be subject to a uniform 25% enterprise income tax ("EIT"), rate on its global income. The Notice Regarding the Determination of Chinese-Controlled Offshore-Incorporated Enterprises as Chinese Tax Resident Enterprises on the Basis of De Facto Management Bodies ("SAT Circular 82"), issued by the State Taxation Administration of the People's Republic of China ("SAT") on April 22, 2009 and as amended in November 2013 and December 2017 further specifies certain criteria for the determination of what constitutes "de facto management bodies." If all of these criteria are met, the relevant foreign enterprise may be regarded to have its "de facto management bodies" located in China and therefore be considered a Chinese resident enterprise. These criteria include: (i) the enterprise's day-to-day operational management is primarily exercised in China; (ii) decisions relating to the enterprise's financial and human resource matters are made or subject to approval by organizations or personnel in China; (iii) the enterprise's primary assets, accounting books and records, company seals, and board and shareholders' meeting minutes are located or maintained in China; and (iv) 50% or more of voting board members or senior executives of the enterprise habitually reside in China. Although SAT Circular 82 only applies to foreign enterprises that are majority-owned and controlled by Chinese enterprises, not those owned and controlled by foreign enterprises or individuals, the determining

[**Table of Contents**](#TOC)

criteria set forth in SAT Circular 82 may be adopted by the Chinese tax authorities as the reference for determining whether the enterprises are Chinese tax residents, regardless of whether they are majority-owned and controlled by Chinese enterprises.

We believe that neither we nor any of our subsidiaries outside of China is a China resident enterprise for Chinese tax purposes. However, the tax resident status of an enterprise is subject to determination by the Chinese tax authorities, and uncertainties remain with respect to the interpretation of the term "de facto management body." If the Chinese tax authorities determine that we or any of our subsidiaries outside of China is a Chinese resident enterprise for EIT purposes, that entity would be subject to a 25% EIT on its global income. If such entity derives income other than dividends from its wholly-owned subsidiaries in China, a 25% EIT on its global income may increase our tax burden.

In addition, if we are classified as a China resident enterprise for Chinese tax purposes, we may be required to withhold tax at a rate of 10% from dividends we pay to our shareholders, including the holders of our ADSs, that are non-resident enterprises. Further, non-resident enterprise shareholders (including our ADS holders) may be subject to a 10% Chinese withholding tax on gains realized on the sale or other disposition of our ADSs or ordinary shares if such income is treated as sourced from within China. Furthermore, gains derived by our non-Chinese individual shareholders from the sale of our ordinary shares and ADSs may be subject to a 20% Chinese withholding tax. It is unclear whether our non-China-based individual shareholders (including our ADS holders) would be subject to any Chinese tax (including withholding tax) on dividends received by such non-Chinese individual shareholders in the event we are determined to be a China resident enterprise. If any Chinese tax were to apply to such dividends, it would generally apply at a rate of 20%. Chinese tax liability may vary under applicable tax treaties. However, it is unclear whether our non-China shareholders would be able to claim the benefits of any tax treaties between their country of tax residence and China in the event that we are treated as a China resident enterprise.

***We and our shareholders face uncertainties in China with respect to indirect transfers of equity interests in China resident enterprises.***

The indirect transfer of equity interests in China resident enterprises by a non-China resident enterprise ("Indirect Transfer"), is potentially subject to income tax in China at a rate of 10% on the gain if such transfer is considered as not having a commercial purpose and is carried out for tax avoidance. The SAT has issued several rules and notices to tighten the scrutiny over acquisition transactions in recent years. The Announcement of the State Administration of Taxation on Several Issues Concerning the Enterprise Income Tax on Indirect Property Transfer by Non-Resident Enterprises ("SAT Circular 7"), sets out the scope of Indirect Transfers, which includes any changes in the shareholder's ownership of a foreign enterprise holding Chinese assets directly or indirectly in the course of a group's overseas restructuring, and the factors to be considered in determining whether an Indirect Transfer has a commercial purpose. An Indirect Transfer satisfying all the following criteria will be deemed to lack a bona fide commercial purpose and be taxable under Chinese laws: (i) 75% or more of the equity value of the intermediary enterprise being transferred is derived directly or indirectly from the Chinese taxable assets; (ii) at any time during the one-year period before the indirect transfer, 90% or more of the asset value of the intermediary enterprise (excluding cash) is comprised directly or indirectly of investments in China, or 90% or more of its income is derived directly or indirectly from China; (iii) the functions performed and risks assumed by the intermediary enterprise and any of its subsidiaries that directly or indirectly hold the Chinese taxable assets are limited and are insufficient to prove their economic substance; and (iv) the non-Chinese tax payable on the gain derived from the indirect transfer of the Chinese taxable assets is lower than the potential Chinese income tax on the direct transfer of such assets. A transaction that does not satisfy all four tests in the immediately preceding sentence may nevertheless be deemed to lack a bona fide commercial purpose if the taxpayer cannot justify such purpose from a totality approach, taking into account the transferred group's value, income, asset composition, the history and substance in the structure, the non-Chinese tax implications, any tax treaty benefit and the availability of alternative transactions. Nevertheless, a non-resident enterprise's buying and selling shares or ADSs of the same listed foreign enterprise on the public market will fall under the safe harbor available under

[**Table of Contents**](#TOC)

SAT Circular 7 if the shares and ADSs were purchased on the public market as well and will not be subject to Chinese tax pursuant to SAT Circular 7.

We face uncertainties regarding the reporting required for and impact on future private equity financing transactions, share exchanges or other transactions involving the transfer of shares in our company by investors that are non-Chinese resident enterprises, or the sale or purchase of shares in other non-Chinese resident companies or other taxable assets by us. For example, the Chinese tax authorities may consider that a future securities offering involves an indirect change of shareholding in our Chinese subsidiaries and therefore it may be regarded as an Indirect Transfer under SAT Circular 7. Even if we believe no SAT Circular 7 reporting is required on the basis that such an offering has commercial purposes and is not conducted for tax avoidance, Chinese tax authorities may pursue us to report under SAT Circular 7 and request that we and our Chinese subsidiaries assist in the filing. As a result, we and our subsidiaries may be required to expend significant resources to provide assistance and comply with SAT Circular 7, or establish that we or our non-resident enterprises should not be subject to tax under SAT Circular 7, for such an offering or other transactions, which may have an adverse effect on our and their financial condition and day-to-day operations.

***Any failure to comply with Chinese regulations regarding the registration requirements for our employee equity incentive plans may subject us to fines and other legal or administrative sanctions, which could adversely affect our business, financial condition and results of operations.***

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 (the "Stock Option Rules"). In accordance with the Stock Option Rules and other relevant rules and regulations, Chinese citizens or non-Chinese 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 SAFE through a domestic qualified agent, which could be a Chinese subsidiary of such overseas listed company, and complete certain procedures. We and our employees who are Chinese citizens or who reside in China for a continuous period of not less than one year and who participate in our stock incentive plans are subject to such regulation. We plan to assist our employees to register their equity awards. However, any failure of our Chinese individual beneficial owners and holders of equity awards to comply with the SAFE registration requirements may subject them to fines and legal sanctions and may limit the ability of our Chinese subsidiaries to distribute dividends to us. We also face regulatory uncertainties that could restrict our ability to adopt additional incentive plans for our directors and employees under Chinese law.

#### Risks Related to Our Intellectual Property
***If we are unable to obtain and maintain sufficient intellectual property protection for our platform technologies and product candidates, or if the scope of the intellectual property protection is not sufficiently broad, our competitors could develop and commercialize products similar or identical to ours, and our ability to successfully commercialize our products may be adversely affected.***

We rely upon a combination of patents, trademarks, trade secret protection and confidentiality agreements to protect the intellectual property related to our products and technologies and to prevent third parties from copying and surpassing our achievements, thus eroding our competitive position in our markets. Our success depends in large part on our ability to obtain and maintain patent protection for our product candidates and their intended uses, maintain trade secret protection of our platform technologies, as well as our ability to operate without infringing the proprietary rights of others. We seek to protect our proprietary position by filing patent applications in the United States and abroad related to our novel discoveries and technologies that are important to our business. Our pending and future patent applications may not result in patents being issued, or may not result in issued patents that will afford sufficient protection of our product candidates or their intended uses against competitors, nor can there be any assurance that the patents issued will not be

[**Table of Contents**](#TOC)

infringed, designed around, invalidated by third parties, or effectively prevent others from commercializing competitive technologies or products.

Obtaining and enforcing patents is expensive and time-consuming, and we may not be able to file and prosecute all necessary or desirable patent applications or maintain and/or enforce patents that may issue based on our patent applications, at a reasonable cost or in a timely manner, including due to delays as a result of global pandemics impacting our or our licensors' operations. Further, we may decide to not pursue or seek patent protection in all relevant markets. It is also possible that we will fail to identify patentable aspects of our research and development results before it is too late to obtain patent protection. Although we enter into non-disclosure and confidentiality agreements with parties who have access to patentable aspects of our research and development output, such as our employees, corporate collaborators, outside scientific collaborators, contract research organizations, contract manufacturers, consultants, advisors and other third parties, any of these parties may breach these agreements and disclose such results before a patent application is filed, thereby jeopardizing our ability to seek patent protection. If we delay in filing a patent application, and a competitor files a patent application on the same or a similar technology before we do, we may face a limited ability to secure patent rights. Or we may not be able to obtain a patent on such technology at all. Even if we can patent the technology, we may be able to patent only a limited scope of the technology, and the limited scope may be inadequate to protect our product candidates, or to block competitor products or product candidates that are similar to ours.

Composition of matter patents for pharmaceutical product candidates often provide a strong form of intellectual property protection for those types of products, as such patents provide protection without regard to any method of use. The claims in our pending patent applications directed to composition of matter of our product candidates may not be considered patentable by the United States Patent and Trademark Office ("USPTO") or by patent offices in foreign countries, or that the claims in any of our issued patents will be considered valid and enforceable by courts in the United States or foreign countries. Method of use patents protect the use of a product for the specified method. This type of patent does not prevent a competitor from making and marketing a product that is identical to our product for an indication that is outside the scope of the patented method. Moreover, even if competitors do not actively promote their product for our targeted indications, physicians may prescribe these products "off-label." Although off-label prescriptions may infringe or contribute to the infringement of method of use patents, the practice is common and such infringement is difficult to prevent or prosecute.

The patent position of biopharmaceutical companies generally is highly uncertain, involves complex legal and factual questions for which many legal principles continue to change. In recent years, patent rights have been the subject of much litigation. As a result, the issuance, scope, validity, enforceability and commercial value of our patent rights are highly uncertain. 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. In addition, the laws of foreign countries may not protect our rights to the same extent as the laws of the United States, or vice versa.

***We cannot ensure that patent rights relating to inventions described and claimed in our pending patent applications will issue or that patents based on our patent applications will not be challenged and rendered invalid and/or unenforceable.***

The patent application process is subject to numerous risks and uncertainties, and we or any of our potential future collaborators may not be successful in protecting our product candidates by obtaining and defending patents. For example, we may not be aware of all third-party intellectual property rights potentially relating to our product candidates or their intended uses, and as a result the impact of such third-party intellectual property rights upon the patentability of our own patents and patent applications, as well as the impact of such third-party intellectual property upon our freedom to operate, is highly uncertain. Patent applications in the United States and other foreign jurisdictions are typically not published until 18 months after filing or, in some cases, not at all. Therefore, we cannot know with certainty whether 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

[**Table of Contents**](#TOC)

protection of such inventions. As a result, the issuance, inventorship, scope, validity, enforceability and commercial value of our patent rights are highly uncertain. We or any of our potential future collaborators may not be successful in protecting our product candidates by obtaining and defending patents. We have pending U.S. and foreign patent applications in our portfolio; however, we cannot predict:

● if and when patents may issue based on our patent applications;

● the scope of protection of any patent issuing based on our patent applications;

● whether the claims of any patent issuing based on our patent applications will provide protection against competitors;

● whether or not third parties will find ways to invalidate or circumvent our patent rights;

● whether or not others will obtain patents claiming aspects similar to those covered by our patents and patent applications;

● whether we will need to initiate litigation or administrative proceedings to enforce and/or defend our patent rights which will be costly whether we win or lose;

● whether the patent applications that we own or in-license will result in issued patents with claims that cover our product candidates or uses thereof in the United States or in other foreign countries; and/or

● whether we may experience patent office interruption or delays to our ability to timely secure patent coverage to our product candidates.

The claims in our pending patent applications directed to our product candidates and/or technologies may not be considered patentable by the USPTO or by patent offices in foreign countries. Any such patent applications may not be issued as granted patents. One aspect of the determination of patentability of our inventions depends on the scope and content of the "prior art," information that was or is deemed available to a person of skill in the relevant art prior to the priority date of the claimed invention. There may be prior art of which we are not aware that may affect the patentability of our patent claims or, if issued, affect the validity or enforceability of a patent claim. There may be double patenting among our own patents, which the patent examiner(s) fail to raise during prosecution. Even if the patents do issue based on our patent applications, third parties may challenge the validity, enforceability or scope thereof, which may result in such patents being narrowed, invalidated or held unenforceable. Furthermore, even if they are unchallenged, patents in our portfolio may not adequately exclude third parties from practicing relevant technology or prevent others from designing around our claims. If the breadth or strength of our intellectual property position with respect to our product candidates is threatened, it could dissuade companies from collaborating with us to develop and threaten our ability to commercialize our product candidates.

Our pending patent applications may be challenged in the USPTO or in patent offices in foreign countries. Also, because the issuance of a patent is not conclusive as to its scope, validity or enforceability, even issued patents may later be found invalid or unenforceable or may be modified or revoked in proceedings instituted by third parties before various patent offices or in courts. For example, our pending patent applications may be subject to third-party pre-issuance submissions of prior art to the USPTO or patent offices in foreign countries or our issued patents may be subject to post-grant review ("PGR") proceedings, oppositions, derivations, reexaminations, or *inter partes* review ("IPR") proceedings, in the United States or elsewhere, challenging our patent rights or the patent rights of others. An adverse determination in any such challenges may result in loss of exclusivity or in our patent claims being narrowed, invalidated, or held unenforceable, in whole or in part, which could limit our ability to stop others from using or commercializing similar or identical technologies and products, or limit the duration of the patent protection of our technologies and product candidates. In addition, given the amount of time required for the development, testing and regulatory review of new product candidates, patents protecting such candidates might expire before or shortly after such candidates are commercialized. As a result, only limited protection may be available and our patent portfolio may not provide us with sufficient rights or permit us to gain or keep any competitive advantage. Any failure to

[**Table of Contents**](#TOC)

obtain or maintain patent protection with respect to our product candidates or their uses could have a material adverse effect on our business, financial condition, results of operations and prospects.

***We rely on trade secret and proprietary know-how which can be difficult to trace and enforce and, if we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed.***

In addition to seeking patent protection for our product candidates and technologies, we rely on trade secret protection and confidentiality agreements to protect proprietary know-how that is not patentable, processes for which patents are difficult to enforce and any other elements of our discovery and development processes that involve proprietary know-how, information or technology that is not covered by patents. Elements of our product candidates, including processes for their preparation and manufacture, may involve proprietary know-how, information, or technology that is not covered by patents, and thus for these aspects we may consider trade secrets and know-how to be our primary intellectual property. We may also rely on trade secret protection as temporary protection for concepts that may be included in a future patent filing. We expect to rely on CROs and third parties to generate chemical molecules and important research data. Any disclosure, either intentional or unintentional, by our employees or third-party consultants and vendors or CROs that we engage to perform research, clinical studies or manufacturing activities, or misappropriation by third parties (such as through a cybersecurity breach) of our trade secrets or proprietary information could enable competitors to duplicate or surpass our technological achievements, thus eroding our competitive position in our market. Because we expect to rely on third parties in the development and manufacture of our product candidates, we must, at times, share trade secrets with them. Our reliance on third parties requires us to share our trade secrets, which increases the possibility that a competitor will discover them or that our trade secrets will be misappropriated or disclosed.

However, trade secret protection will not protect us from innovations that a competitor develops independently of our proprietary know-how. If a competitor independently develops a technology that we protect as a trade secret and files a patent application on that technology, then we may not be able to patent that technology in the future, may require a license from the competitor to use our own know-how, and if the license is not available on commercially-viable terms, then we may not be able to complete development of, or commercialize, our products. Although we require all of our employees, consultants, collaborators, CROs, contract manufacturers, advisors and any third parties who have access to our proprietary know-how, information or technologies to enter into confidentiality agreements, we cannot guarantee that we have entered into such agreements with each party that may have or has had access to our trade secrets or proprietary technology and processes. We cannot be certain that our trade secrets and other confidential proprietary information may not be disclosed or that competitors will not otherwise gain access to our trade secrets or independently develop substantially equivalent information and techniques. Despite these efforts, any of these parties may breach the agreements and disclose our proprietary information, including our trade secrets, and we may not be able to obtain adequate remedies for such breaches. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret is difficult, expensive and time-consuming, and the outcome is unpredictable. Furthermore, the laws of some foreign countries do not protect proprietary rights to the same extent or in the same manner as the laws of the United States. As a result, we may encounter significant problems in protecting and defending our intellectual property both in the United States and abroad. We may need to share our proprietary information, including trade secrets, with future business partners, collaborators, contractors and others located in countries at heightened risk of theft of trade secrets, including through direct intrusion by private parties or foreign actors, and those affiliated with or controlled by state actors. We also seek to preserve the integrity and confidentiality of our data and trade secrets by maintaining physical security of our premises and physical and electronic security of our information technology systems. While we have confidence in these individuals, organizations and systems, agreements or security measures may be breached, and we may not have adequate remedies for any breach. If we are unable to prevent unauthorized material disclosure of our intellectual property to third parties, we will not be able to establish or maintain a competitive advantage in our market, and this scenario could materially adversely affect our business, financial condition and results of operations.

[**Table of Contents**](#TOC)

***We may rely on one or more in-licenses from third parties. If we lose these rights, our business may be materially adversely affected, and if disputes arise with one or more licensors, we may be subjected to future litigation as well as the potential loss of or limitations on our ability to develop and commercialize products and technologies covered by these license agreements.***

The growth of our business may depend in part on our ability to acquire or in-license additional proprietary rights. We may be unable to acquire or in-license any relevant third-party intellectual property rights that we identify as necessary or important to our business operations. We may fail to obtain any of these licenses at a reasonable cost or on reasonable terms, if at all, which would adversely affect our business. We may need to cease use of the technology covered by such third-party intellectual property rights, and may need to seek to develop alternative approaches that do not infringe on such intellectual property rights which may entail additional costs and development delays, even if we were able to develop such alternatives, which may not be feasible. Even if we are able to obtain a license under such intellectual property rights, any such license may be non-exclusive, and may allow our competitors access to the same technologies licensed to us. The licensing and acquisition of third-party intellectual property rights is a competitive practice, and companies that may be more established, or have greater resources than we do, may also be pursuing strategies to license or acquire third-party intellectual property rights that we may consider necessary or attractive for commercializing our product candidates. More established companies may have a competitive advantage over us due to their larger size and cash resources or greater clinical development and commercialization capabilities. We may not be able to successfully complete such negotiations and ultimately acquire the rights to the intellectual property surrounding the additional product candidates and technology that we may seek to acquire.

We may in the future enter into license agreements with third parties under which we receive rights to intellectual property that are important to our business. Our rights to use the technology we license are subject to the continuation of and compliance with the terms of those agreements. These intellectual property license agreements may require various development, regulatory and/or commercial diligence obligations, payment of milestones and/or royalties and other obligations. If we fail to comply with our obligations under these agreements, we use the licensed intellectual property in an unauthorized manner or we are subject to bankruptcy-related proceedings, the terms of the license agreements may be materially modified, such as by rendering currently exclusive licenses non-exclusive, or it may give our licensors the right to terminate their respective agreement with us, which could limit our ability to implement our current business plan and materially adversely affect our business, financial condition, results of operations and prospects.

We may also in the future enter into license agreements with third parties under which we are a sublicensee. If our sublicensor fails to comply with its obligations under its upstream license agreement with its licensor, the licensor may have the right to terminate the upstream license, which may terminate our sublicense. If this were to occur, we would no longer have rights to the applicable intellectual property unless we are able to secure our own direct license with the owner of the relevant rights, which we may not be able to do on reasonable terms, or at all, which may impact our ability to continue to develop and commercialize our product candidates incorporating the relevant intellectual property.

In some cases, we may not control the prosecution, maintenance or filing of the patents to which we hold licenses, or the enforcement of those patents against third parties. Hence, our success will depend in part on the ability of our licensors to obtain, maintain and enforce patent protection for our licensed intellectual property, in particular, those patents to which we have secured exclusive rights. Our licensors may not successfully prosecute the patent applications to which we are licensed in a manner consistent with the best interests of our business. Even if patents are issued in respect of these patent applications, our licensors may fail to maintain these patents, may determine not to pursue litigation against other companies that are infringing these patents, or may pursue such litigation less aggressively than we would. Without protection for the intellectual property we license, other companies might be able to offer substantially identical products for sale, which could adversely affect our competitive business position and harm our business prospects. Further, we may have limited control over these activities or any other intellectual property that may be in-licensed. For example, we cannot be certain that such activities by licensors have been or will be conducted

[**Table of Contents**](#TOC)

in compliance with applicable laws and regulations or will result in valid and enforceable patents and other intellectual property rights. We may have limited control over the manner in which our licensors initiate an infringement proceeding against a third-party infringer of the intellectual property rights, or defend certain of the intellectual property that is licensed to us. It is possible that the licensors' infringement proceeding or defense activities may be less vigorous than had we conducted them ourselves. In the event our licensors fail to adequately pursue and maintain patent protection for patents and applications they control, and to timely cede control of such prosecution to us, our competitors might be able to enter the market, which would have a material adverse effect on our business.

Moreover, disputes may arise with respect to our licensing or other upstream agreements, including:

● the scope of rights granted under the agreements and other interpretation-related issues;

● whether and the extent to which our systems and consumables, technologies and processes infringe on intellectual property of the licensor that is not subject to the licensing agreement;

● the sublicensing of patent and other rights under our collaborative development relationships;

● our diligence obligations under the license agreements 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 spite of our efforts to comply with our obligations under our in-license agreements, our licensors might conclude that we have materially breached our obligations under our license agreements and might therefore, including in connection with any aforementioned disputes, terminate the relevant license agreement, thereby removing or limiting our ability to develop and commercialize products and technology covered by these license agreements. If any such in-license is terminated, or if the licensed patents fail to provide the intended exclusivity, competitors or other third parties might have the freedom to market or develop products similar to ours. In addition, absent the rights granted to us under such license agreements, we may infringe the intellectual property rights that are the subject of those agreements, we may be subject to litigation by the licensor, and if such litigation by the licensor is successful we may be required to pay damages to such licensor, or we may be required to cease our development and commercialization activities which are deemed infringing, and in such event we may ultimately need to modify our activities or products to design around such infringement, which may be time- and resource-consuming, and which may not be ultimately successful. Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations and prospects.

In addition, certain of our future agreements with third parties may limit or delay our ability to consummate certain transactions, may impact the value of those transactions, or may limit our ability to pursue certain activities. For example, we may in the future enter into license agreements that are not assignable or transferable, or that require the licensor's express consent in order for an assignment or transfer to take place.

#### Our intellectual property licensed from third parties may be subject to retained rights.
Our future licensors may retain certain rights under their agreements with us, including the right to use the underlying technology for noncommercial academic and research use, to publish general scientific findings from research related to the technology, and to make customary scientific and scholarly disclosures of information relating to the technology. It is difficult to monitor whether our licensors limit their use of the technology to these uses, and we could incur substantial expenses to enforce our rights to our licensed technology in the event of misuse.

[**Table of Contents**](#TOC)

Government agencies may provide funding, facilities, personnel or other assistance in connection with the development of the intellectual property rights owned by or licensed to us. Such government agencies may have retained rights in such intellectual property. The United States federal government retains certain rights in inventions produced with its financial assistance under the Patent and Trademark Law Amendments Act (the "Bayh-Dole Act"); these include the right to grant or require us to grant mandatory licenses or sublicenses to such intellectual property to third parties under certain specified circumstances, including if it is necessary to meet health and safety needs that we are not reasonably satisfying or if it is necessary to meet requirements for public use specified by federal regulations, or to manufacture products in the United States. Any exercise of such rights, including with respect to any such required sublicense of these licenses could result in the loss of significant rights and could harm our ability to commercialize licensed products. While it is our policy to avoid engaging our university partners in projects in which there is a risk that federal funds may be commingled, we cannot be sure that any co-developed intellectual property will be free from government rights pursuant to the Bayh-Dole Act. If, in the future, we co-own or license in technology which is critical to our business that is developed in whole or in part with federal funds subject to the Bayh-Dole Act, our ability to enforce or otherwise exploit patents covering such technology may be adversely affected.

***Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee payment and other requirements imposed by government patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these requirements.***

Periodic maintenance fees, renewal fees, annuity fees and various other government fees on patents and/or applications will be due to be paid to the USPTO and various government patent agencies outside of the United States over the lifetime of our owned and licensed patents and/or applications and any patent rights we may own or license in the future. We rely on our outside counsel, patent annuity service providers, or our licensing partners to pay these fees due to non-U.S. patent agencies. If these fees are not paid to the USPTO or the non-U.S. patent agencies when due, our rights to such patents or patent applications may be abandoned or otherwise materially impaired.

The USPTO and various non-U.S. government patent agencies require compliance with several procedural, documentary, and other similar provisions during the patent application process. For example, many countries, including the U.S. and China, require a foreign filing license to seek patent protection in a country outside of the inventor's or invention's country. Each country's laws regarding foreign filing licenses vary and may even conflict. We employ reputable law firms and other professionals to help us comply and we are also dependent on our licensors to take the necessary action to comply with these requirements with respect to our intellectual property. In many cases, an inadvertent lapse can be cured by payment of a late fee or by other means in accordance with the applicable rules. There are situations, however, in which non-compliance can result in abandonment or lapse of the patent or patent application, resulting in 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, but are not limited to, failure to respond to official actions within prescribed time limits, non-payment of fees and failure to properly legalize and submit formal documents. In such an event, potential competitors might be able to enter the market and this circumstance could harm our business.

***Patent terms may be inadequate to protect our competitive position on our product candidates for an adequate amount of time.***

Patents have a limited lifespan. In the United States, if all maintenance fees are paid timely, the natural expiration of a patent is generally 20 years from the earliest filing date of a non-provisional patent application. Various extensions may be available; however, the life of a patent, and the protection it affords, is limited. For instance, a patent term extension based on regulatory delay may be available in the United States. However, only a single patent can be extended for each marketing approval, and any patent can be extended only once, for a single product. Moreover, the scope of protection during the period of the patent term extension does not necessarily extend to all patent claims, but instead only to patent claims that read on the product as

[**Table of Contents**](#TOC)

approved. Even if patents covering our product candidates are obtained, once the patent life has expired for a product candidate, we may be open to competition.

Given the amount of time required for the development, testing and regulatory review of our new product candidates such as aleniglipron, ACCG-2671, ACCG-3535, ANPA-0073, LTSE-2578 and any of our future product candidates, patents protecting such candidates might expire before or shortly after such candidates are commercialized. We expect to seek extensions of patent terms in the United States and, if available, in other countries where we are prosecuting patents. In the United States, the Drug Price Competition and Patent Term Restoration Act of 1984 permits a patent term extension of up to five years beyond the normal expiration of the patent, which is limited to the approved indication (or any additional indications approved during the period of extension) as compensation for effective patent term lost during product development and FDA regulatory review process. However, we may not receive an extension if we fail to exercise due diligence during the testing phase or regulatory review process, fail to apply within applicable deadlines, fail to apply prior to expiration of relevant patents or otherwise fail to satisfy applicable requirements. Moreover, the length of the extension could be less than we request. Only one patent per approved product can be extended, the extension cannot extend the total patent term beyond 14 years from approval and only those claims covering the approved drug, a method for using it or a method for manufacturing it may be extended. Further, the applicable authorities, including the FDA and the USPTO in the United States, and any equivalent regulatory authority in other countries, may not agree with our assessment of whether such extensions are available, and may refuse to grant extensions to our patents, or may grant more limited extensions than we request. If we are unable to obtain patent term extension or the term of any such extension is less than we request, the period during which we can enforce our patent rights for the applicable product candidate will be shortened and our competitors may obtain approval to market competing products sooner. As a result, our revenue from applicable products could be reduced. Further, if this occurs, our competitors may be able to take advantage of our investment in development and clinical studies by referencing our clinical and preclinical data and launch their product candidates earlier than might otherwise be the case.

#### Intellectual property rights do not necessarily address all potential threats to our business.
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. The following examples are illustrative:

● others may be able to make compounds or formulations that are similar to our product candidates but that are not covered by the claims of any patents that we own or control;

● we or any strategic partners might not have been the first to make the inventions covered by the issued patents or pending patent applications that we own or control;

● we might not have been the first to file patent applications covering certain of the inventions we own or control;

● others may independently develop similar or alternative technologies or duplicate any of our technologies without infringing our intellectual property rights;

● it is possible that noncompliance with the USPTO and foreign governmental agencies requirement for a number of procedural, documentary, fee payment and other provisions during the patent process or technology export can result in abandonment or lapse of a patent or patent application, and partial or complete loss of patent rights in the relevant jurisdiction;

● pending patent applications that we own or control may not lead to issued patents;

● issued patents that we own or control may be held invalid or unenforceable as a result of legal challenges;

[**Table of Contents**](#TOC)

● our competitors might conduct research and development activities in the United States and other foreign countries that provide a safe harbor from patent infringement claims for certain research and development activities, as well as in countries where we do not have patent rights and then use the information learned from such activities to develop competitive product candidates for sale in our major commercial markets;

● we may not develop additional proprietary technologies that are patentable;

● we cannot predict the scope of protection of any patent issuing based on our patent applications, including whether the patent applications that we own or in-license will result in issued patents with claims that directed to our product candidates or uses thereof in the United States or in other foreign countries;

● there may be significant pressure on the U.S. government and international governmental bodies to limit the scope of patent protection both inside and outside the United States for disease treatments that prove successful, as a matter of public policy regarding worldwide health concerns;

● countries other than the United States may have patent laws that are less favorable to patentees than those upheld by U.S. courts, allowing foreign competitors a better opportunity to create, develop and market competing product candidates;

● the claims of any patent issuing based on our patent applications may not provide protection against competitors or any competitive advantages, or may be challenged by third parties;

● if enforced, a court may not hold that our patents are valid, enforceable and infringed;

● we may not develop additional proprietary technologies that are patentable; and

● the patents of others may have an adverse effect on our business, including if others obtain patents claiming subject matter similar to or improving that covered by our patents and patent applications.

***Third parties may initiate legal proceedings alleging that we are infringing, misappropriating or otherwise violating their intellectual property rights, the outcome of which would be uncertain and could have a negative impact on the success of our business.***

Our commercial success depends, in part, upon our ability and the ability of our current or future collaborators to develop, manufacture, market and sell our current and any future product candidates and use our proprietary technologies without infringing the proprietary rights and intellectual property of third parties. The biotechnology and pharmaceutical industries are characterized by extensive and complex litigation regarding patents and other intellectual property rights. Because the intellectual property landscape in the industry in which we participate is rapidly evolving and interdisciplinary, it is difficult to conclusively assess our freedom to operate without infringing on third-party rights. U.S. and foreign issued patents and pending patent applications, which are owned by third parties, exist in the fields relating to our product candidates. As the biotechnology and pharmaceutical industries expand and more patents are issued, the risk increases that others may assert our product candidates infringe the patent rights of others. Moreover, it is not always clear to industry participants, including us, which patents cover various types of drugs, products or their methods of use or manufacture. Thus, because of the large number of patents issued and patent applications filed in our fields, there may be a risk that third parties may allege they have patent rights encompassing our product candidates, technologies or methods.

Our product candidates and other proprietary technologies we may develop may infringe existing or future patents owned by third parties. We may in the future become party to, or be threatened with, adversarial proceedings or litigation regarding intellectual property rights with respect to our current and any future product candidates and technologies, including interference or derivation, PGR and IPR proceedings before the USPTO. Third parties may assert infringement claims against us based on existing patents or patents that may be granted in the future, regardless of their merit. There is a risk that third parties may choose to engage in litigation with us to enforce or to otherwise assert their patent rights against us. Even if we believe such

[**Table of Contents**](#TOC)

claims are without merit, a court of competent jurisdiction could hold that these third-party patents are valid, enforceable and infringed, which could have a negative impact on our ability to commercialize our current and any future product candidates. In order to successfully challenge the validity of any such U.S. patent in federal court, we would need to overcome a presumption of validity. As this burden is a high one requiring us to present clear and convincing evidence as to the invalidity of any such U.S. patent claim, a court of competent jurisdiction may not invalidate the claims of any such U.S. patent. If we are found to infringe a third party's valid and enforceable intellectual property rights, we could be required to obtain a license from such third party to continue developing, manufacturing and marketing our product candidate(s) and technologies. However, we may not be able to obtain any required license on commercially reasonable terms or at all. Even if we were able to obtain a license, it could be non-exclusive, thereby giving our competitors and other third parties access to the same technologies licensed to us, and it could require us to make substantial licensing and royalty payments. We could be forced, including by court order, to cease developing, manufacturing and commercializing the infringing technologies or product candidate, or redesign our product candidates or processes so they do not infringe, which may not be possible or may require substantial monetary expenditures and time. In addition, we could be found liable for monetary damages, including treble damages and attorneys' fees, if we are found to have willfully infringed a patent or other intellectual property right. A finding of infringement could prevent us from manufacturing and commercializing our current or any future product candidates or force us to cease some or all of our business operations, which could materially harm our business. Claims that we have misappropriated the confidential information or trade secrets of third parties could have a similar negative impact on our business, financial condition, results of operations and prospects.

Third parties asserting their patent or other intellectual property rights against us may also seek and obtain injunctive or other equitable relief, which could effectively block our ability to further develop and commercialize our product candidates or force us to cease some of our business operations. Defense of these claims, regardless of their merit, would involve substantial litigation expense and would be a substantial diversion of management and other employee resources from our business, cause development delays, and may impact our reputation.

In addition, if any of our product candidates are found to infringe the intellectual property rights of third parties, these third parties may assert infringement claims against our licensees and other parties with whom we have business relationships, and we may be required to indemnify those parties for any damages they suffer as a result of these claims. The claims may require us to initiate or defend protracted and costly litigation on behalf of licensees and other parties regardless of the merits of these claims. If any of these claims succeed, we may be forced to pay damages on behalf of those parties or may be required to obtain licenses for the products they use.

Some of our competitors may be able to sustain the costs of complex patent litigation more effectively than we can because they have substantially greater resources. In addition, any uncertainties resulting from the initiation and continuation of any litigation could have a material adverse effect on our ability to raise the funds necessary to continue our operations or could otherwise have a material adverse effect on our business, results of operations, financial condition and prospects.

Additionally, during the course of any intellectual property litigation, there could be public announcements of the initiation of the litigation as well as 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 existing product candidates, 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 future products, which could have a material adverse effect on our business.

[**Table of Contents**](#TOC)

***We may become involved in lawsuits to protect or enforce our patents or other intellectual property, which could be expensive, time consuming and unsuccessful.***

Competitors or other third parties may infringe or otherwise violate our patents, trademarks or other intellectual property. To counter infringement or unauthorized use, we may be required to file infringement claims, which can be expensive and time consuming and divert the time and attention of our management and scientific personnel. Our pending patent applications cannot be enforced against third parties practicing the technologies claimed in such applications unless and until a patent issues from such applications. Any claims we assert against perceived infringers could provoke these parties to assert counterclaims against us alleging that we infringe their patents, in addition to counterclaims asserting that our patents are invalid or unenforceable, or both. In patent litigation in the United States, defendant counterclaims alleging invalidity and/or unenforceability are commonplace. Grounds for a validity challenge could be an alleged failure to meet any of several statutory requirements, including lack of novelty, obviousness, non-enablement or insufficient written description. Grounds for an unenforceability assertion could be an allegation that someone connected with prosecution of the patent withheld relevant information from the USPTO or patent offices in foreign countries or made a misleading statement during prosecution. Third parties may also raise similar validity claims before the USPTO in post-grant proceedings such as ex parte reexaminations, IPR, or PGR, or oppositions or similar proceedings outside the United States, in parallel with litigation or even outside the context of litigation. The outcome following legal assertions of invalidity and unenforceability is unpredictable. There may be invalidating prior art, of which we and the patent examiner were unaware during prosecution. There may be double patenting among our own patents, which the patent examiner(s) fail to raise during prosecution. For the patents and patent applications that we have licensed, we may have limited or no right to participate in the defense of any licensed patents against challenge by a third party. If a defendant were to prevail on a legal assertion of invalidity or unenforceability, we would lose at least part, and perhaps all, of any future patent protection on our current or future product candidates. Such a loss of patent protection could harm our business.

In any patent infringement proceeding, there is a risk that a court will decide that a patent of ours is invalid or unenforceable, in whole or in part, and that we do not have the right to stop the other party from using the invention at issue. There is also a risk that, even if the validity of such patents is upheld, the court will construe the patent's claims narrowly or decide that we do not have the right to stop the other party from using the invention at issue on the grounds that our patent claims do not cover the invention, or decide that the other party's use of our patented technologies falls under the safe harbor to patent infringement under 35 U.S.C. §271(e)(1). An adverse outcome in a litigation or other proceeding involving our patents could limit our ability to assert our patents against those parties or other competitors and may curtail or preclude our ability to exclude third parties from making and selling similar or competitive products. In addition, if the breadth or strength of protection provided by our patents and patent applications or those of our future licensors is threatened, it could dissuade other companies from collaborating with us to license, develop or commercialize current or future product candidates. Any of these occurrences could adversely affect our competitive business position, business prospects and financial condition. Similarly, if we assert trademark infringement claims, a court may determine that the marks we have asserted are invalid or unenforceable, or that the party against whom we have asserted trademark infringement has superior rights to the marks in question. In such case, we could ultimately be forced to cease use of such trademarks. In any intellectual property litigation, even if we are successful, any award of monetary damages or other remedy we receive may not be commercially valuable.

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 or may not be an adequate remedy. 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 litigation. There could also be public announcements of the results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive these results to be negative, it could have a material adverse effect on the price of our ADSs. Moreover, we cannot assure you that we will have sufficient financial or other resources to file and pursue such infringement claims, which typically last for years

[**Table of Contents**](#TOC)

before they are concluded. Even if we ultimately prevail in such claims, the monetary cost of such litigation and the diversion of the attention of our management and scientific personnel could outweigh any benefit we receive as a result of the proceedings.

Further, interference or derivation proceedings provoked by third parties or brought by the USPTO or patent offices in foreign countries may be necessary to determine the priority of inventions with respect to, or the correct inventorship of, our patents or patent applications or those of our licensors. An unfavorable outcome could result in a loss of our current patent rights and could require us to cease using the related technologies or to attempt to license rights to it from the prevailing party. Our business could be harmed if the prevailing party does not offer us a license on commercially reasonable terms. Litigation, interference, derivation or other proceedings may result in a decision adverse to our interests and, even if we are successful, may result in substantial costs and distract our management and other employees.

We may not be able to prevent, alone or with our licensors, misappropriation of our intellectual property rights, particularly in countries where the laws may not protect those rights as fully as in the United States. Any litigation or other proceedings to enforce our intellectual property rights may fail, and even if successful, may result in substantial costs and distract our management and other employees.

***Because of the expense and uncertainty of litigation, we may not be in a position to enforce our intellectual property rights against third parties.***

Because of the expense and uncertainty of litigation, we may conclude that even if a third party is infringing our issued patent, any patents that may be issued as a result of our pending or future patent applications or other intellectual property rights, the risk-adjusted cost of bringing and enforcing such a claim or action may be too high or not in the best interest of our company or our shareholders, or it may be otherwise impractical or undesirable to enforce our intellectual property against some third parties. Our competitors or other third parties may be able to sustain the costs of complex patent litigation or proceedings more effectively than we can because of their greater financial resources and more mature and developed intellectual property portfolios. In such cases, we may decide that the more prudent course of action is to simply monitor the situation or initiate or seek some other non-litigious action or solution. In addition, the uncertainties associated with litigation could compromise our ability to raise the funds necessary to continue our clinical studies, continue our internal research programs, in-license needed technologies or other product candidates, or enter into development partnerships that would help us bring our product candidates to market.

***Changes in U.S. patent law or the patent law of other countries or jurisdictions could diminish the value of patents in general, thereby impairing our ability to protect our current and any future product candidates.***

Changes in either the patent laws or interpretation of the patent laws in the United States and other foreign countries could increase uncertainties and costs, and may diminish our ability to protect our inventions, obtain, maintain, and enforce our intellectual property rights and, more generally, could affect the value of our patents or narrow the scope of our patent protection. On September 16, 2011, the Leahy-Smith America Invents Act (the "Leahy-Smith Act") was signed into law. When implemented, the Leahy-Smith Act included several significant changes to U.S. patent law that impacted how patent rights could be prosecuted, enforced and defended. These include provisions that affect the way patent applications are prosecuted, redefine prior art and provide more efficient and cost-effective avenues for competitors to challenge the validity of patents. These include allowing third-party submission of prior art to the USPTO during patent prosecution and additional procedures to attack the validity of a patent by USPTO administered post-grant proceedings, including PGR, IPR, and derivation proceedings. Further, because of a lower evidentiary standard in these USPTO post-grant proceedings compared to the evidentiary standard in United States federal courts necessary to invalidate a patent claim, a third party could potentially provide evidence in a USPTO proceeding sufficient for the USPTO to hold a patent claim invalid even though the same evidence would be insufficient to invalidate the patent claim if first presented in a district court action. Accordingly, a third party may attempt to use the USPTO procedures to invalidate our patent claims that would not have been

[**Table of Contents**](#TOC)

invalidated if first challenged by the third party as a defendant in a district court action. Thus, the Leahy-Smith Act and its implementation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents, all of which could have a material adverse effect on our business, financial condition, results of operations and prospects.

In addition, under the Leahy-Smith Act, the United States transitioned from a "first-to-invent" system to a "first-to-file" system in which, assuming that the other statutory requirements are met, the first inventor to file a patent application will be entitled to the patent on an invention regardless of whether a third party was the first to invent the claimed invention. A third party that files a patent application in the USPTO after March 2013, but before we file an application covering the same invention, could therefore be awarded a patent covering an invention of ours even if we had made the invention before it was made by such third party. This will require us to be cognizant going forward of the time from invention to filing of a patent application. Since patent applications in the United States and most other countries are confidential for a period of time after filing or until issuance, we cannot be certain that we or our licensors were the first to either (i) file any patent application related to our product candidates and other proprietary technologies we may develop or (ii) invent any of the inventions claimed in our or our licensor's patents or patent applications. Even where we have a valid and enforceable patent, we may not be able to exclude others from practicing the claimed invention where the other party can show that they used the invention in commerce before our filing date or the other party benefits from a compulsory license.

The USPTO developed new regulations and procedures governing the administration of the Leahy-Smith Act, and many of the substantive changes to patent law associated with the Leahy-Smith Act, and in particular, the first to file provisions, became effective on March 16, 2013. It remains unclear what, if any, impact the Leahy-Smith Act will have on the operation of our business. However, the Leahy-Smith Act and its implementation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents, all of which could have a negative effect on our business.

In addition, the U.S. Supreme Court has ruled on several patent cases in recent years, either narrowing the scope of patent protection available in certain circumstances or weakening the rights of patent owners in certain situations. In addition to increasing uncertainty with regard to our ability to obtain patents in the future, this combination of events has created uncertainty with respect to the value of patents, once obtained. Depending on actions by the U.S. Congress, the federal courts, and the USPTO, the laws and regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce patents that we have licensed or that we might obtain in the future. Similarly, changes in patent law and regulations in other countries or jurisdictions or changes in the governmental bodies that enforce them or changes in how the relevant governmental authority enforces patent laws or regulations may weaken our ability to obtain new patents or to enforce patents that we have licensed or that we may obtain in the future.

***We may not be able to protect our intellectual property rights throughout the world, which could negatively impact our business.***

Filing, prosecuting and defending patents covering our current and any future product candidates throughout the world would be prohibitively expensive, and our intellectual property rights in some countries outside the United States can have a different scope and strength than do those in the United States. Consequently, we may not be able to prevent third parties from practicing our inventions in all countries outside the United States, or from selling or importing products made using our inventions in and into the United States or other countries. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop their own product candidates and, further, may export otherwise infringing product candidates to territories where we may obtain patent protection, but where patent enforcement is not as strong as that in the United States. These product candidates may compete with our product candidates in jurisdictions where we do not have any issued or licensed patents and any future patent claims or other intellectual property rights may not be effective or sufficient to prevent them from so competing.

[**Table of Contents**](#TOC)

Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents, trade secrets and other intellectual property, particularly those relating to biopharmaceutical products, which could make it difficult in those jurisdictions for us to stop the infringement or misappropriation of our patents or other intellectual property rights, or the marketing of competing products in violation of our proprietary rights. Proceedings to enforce our patent and other intellectual property rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business. Furthermore, such proceedings could put our patents at risk of being invalidated, held unenforceable, or interpreted narrowly, could put our patent applications at risk of not issuing, and could provoke third parties to assert claims of infringement or misappropriation 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. Similarly, if our trade secrets are disclosed in a foreign jurisdiction, competitors worldwide could have access to our proprietary information and we may be without satisfactory recourse.

Such disclosure could have a material adverse effect on our business. Moreover, our ability to protect and enforce our intellectual property rights may be adversely affected by unforeseen changes in foreign intellectual property laws. In addition, certain developing countries, including China and India, have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties. In those countries, we and our licensors may have limited remedies if patents are infringed or if we or our licensors are compelled to grant a license to a third party, which could materially diminish the value of those patents. In addition, many countries limit the enforceability of patents against government agencies or government contractors. This could limit our potential revenue opportunities. 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.

***We may be subject to claims that our employees, consultants, or advisors have wrongfully used or disclosed trade secrets or other confidential information of their current or former employers or claims asserting inventorship or ownership of what we regard as our own intellectual property.***

Many of our employees, consultants, and advisors are currently or were previously employed at universities or other healthcare, biotechnology or pharmaceutical companies, including our competitors or potential competitors. Although we try to ensure that our employees, consultants, and advisors 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 individuals have used or disclosed intellectual property, including trade secrets or other proprietary information, of any such individual's current or former employer or client. Litigation may be necessary to defend against these 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.

We may be subject to claims that former employees, collaborators, or other third parties have an interest in our patents or other intellectual property as an inventor or co-inventor. The failure to name the proper inventors on a patent application can result in the patents issuing thereon being invalid or unenforceable. Inventorship disputes may arise from conflicting views regarding the contributions of different individuals named as inventors, the effects of foreign laws where foreign nationals are involved in the development of the subject matter of the patent, conflicting obligations of third parties involved in developing our product candidates or as a result of questions regarding co-ownership of potential joint inventions. For example, we may have inventorship disputes arise from conflicting obligations of consultants or others who are involved in developing our product candidates. Litigation may be necessary to defend against these and other claims challenging inventorship. Alternatively, or additionally, we may enter into agreements to clarify the scope of our rights in such intellectual property. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights, such as exclusive ownership of, or right to use, valuable intellectual property. Such an outcome could have a material adverse effect on our business. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to our management and other employees.

[**Table of Contents**](#TOC)

Our licensors may have relied on third-party consultants or collaborators or on funds from third parties, such as the U.S. government, such that our licensors are not the sole and exclusive owners of the patents we in-licensed. If other third parties have ownership rights or other rights to our in-licensed patents, they may be able to license such patents to our competitors, and our competitors could market competing product candidates and technology. This could have a material adverse effect on our competitive position, business, financial conditions, results of operations, and prospects.

In addition, while it is our policy to require our employees and contractors who may be involved in the conception or 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, conceives or develops intellectual property that we regard as our own. The assignment of intellectual property rights may not be self-executing, or the assignment agreements may be breached, and we may be forced to bring claims against third parties, or defend claims that they may bring against us, to determine the ownership of what we regard as our intellectual property. Such claims could have a material adverse effect on our business, financial condition, results of operations, and prospects.

***We may not identify relevant third-party patents or may incorrectly interpret the relevance, scope or expiration of a third-party patent, which might adversely affect our ability to develop and market our products.***

Any of our patent searches or analyses, including the identification of relevant patents, the scope of patent claims or the expiration of relevant patents, may not be complete or thorough, nor can we be certain that we have identified each and every third-party patent and pending application in the United States and abroad that is relevant to or necessary for the commercialization of our product candidates in any jurisdiction. The scope of a patent claim is determined by an interpretation of the law, the written disclosure in a patent and the patent's prosecution history. Our interpretation of the relevance or the scope of a patent or a pending application may be incorrect, which may negatively impact our ability to market our products. For example, we may incorrectly determine that our products are not covered by a third-party patent or may incorrectly predict whether a third party's pending application will issue with claims of relevant scope. Also, our determination of the expiration date of any patent in the United States or abroad that we consider relevant may be incorrect, which may negatively impact our ability to develop and market our product candidates. Our failure to identify and correctly interpret relevant patents may negatively impact our ability to develop and market our products.

One aspect of the determination of patentability of our inventions depends on the scope and content of the "prior art," information that was or is deemed available to a person of skill in the relevant art prior to the priority date of the claimed invention. There may be prior art of which we are not aware that may affect the patentability of the claims of our patent applications or, if issued, affect the validity or enforceability of a patent claim. Further, we may not be aware of all third-party intellectual property rights potentially relating to our product candidates or their intended uses, and as a result the impact of such third-party intellectual property rights upon the patentability of our own patents and patent applications, as well as the impact of such third-party intellectual property upon our freedom to operate, is highly uncertain. Because patent applications in the United States and most other countries are confidential for typically a period of 18 months after filing, or may not be published at all, we may not be the first to file any patent application related to our product candidates. As a result, the issuance, scope, validity, enforceability and commercial value of our patent rights are highly uncertain. Furthermore, for U.S. applications in which all claims are entitled to a priority date before March 16, 2013, an interference proceeding can be provoked by a third party or instituted by the USPTO to determine who was the first to invent any of the subject matter covered by the patent claims of our applications. For U.S. applications containing a patent claim not entitled to priority before March 16, 2013, there is a greater level of uncertainty in the patent law in view of the passage of the Leahy-Smith Act, which brought into effect significant changes to the U.S. patent laws, including new procedures for challenging pending patent applications and issued patents.

***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 business may be adversely affected.***

Our current or future trademarks or trade names may be challenged, opposed, infringed, circumvented, invalidated, cancelled, declared generic, determined to be not entitled to registration, or determined to be infringing on other marks. During trademark registration proceedings, we may receive rejections of our applications by the USPTO or in foreign jurisdictions. Although we would be given an opportunity to respond to those rejections, we may be unable to overcome such rejections. In addition, in the USPTO and in comparable agencies in many foreign jurisdictions, third parties are given an opportunity to oppose pending trademark applications and to seek to cancel registered trademarks. Opposition or cancellation proceedings may be filed against our trademarks, and our trademarks may not survive such proceedings. Any trademark litigation could be expensive. In addition, we could be found liable for significant monetary damages, including treble damages, disgorgement of profits and attorneys' fees, if we are found to have willfully infringed a trademark. We may not be able to protect our exclusive right to these trademarks and trade names or may be forced to stop using these names, which we need for name recognition by potential collaborators or customers in our markets of interest. 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. We may license our trademarks and trade names to third parties, such as distributors. Though these license agreements may provide guidelines for how our trademarks and trade names may be used, a breach of these agreements or misuse of our trademarks and tradenames by our licensees may jeopardize our rights in or diminish the goodwill associated with our trademarks and trade names.

Moreover, any name we have proposed to use with our product candidates in the United States must be approved by the FDA, regardless of whether we have registered it, or applied to register it, as a trademark. Similar requirements exist in Europe. The FDA typically conducts a review of proposed product names, including an evaluation of potential for confusion with other product names. If the FDA (or an equivalent administrative body in a foreign jurisdiction) objects to any of our proposed proprietary product names, it may be required to expend significant additional resources in an effort to identify a suitable substitute name that would qualify under applicable trademark laws, not infringe the existing rights of third parties and be acceptable to the FDA. Furthermore, in many countries, owning and maintaining a trademark registration may not provide an adequate defense against a subsequent infringement claim asserted by the owner of a senior trademark.

#### Risks Related to Our ADSs

#### The price of our ADSs may be volatile, and you could lose all or part of your investment.
The trading price of our ADSs is likely to be highly volatile and could be subject to wide fluctuations in response to various factors, some of which are beyond our control, including limited trading volume. In addition to the factors discussed in this "Risk Factors" section and elsewhere in this Quarterly Report, these factors include:

● the commencement, enrollment or results of our ongoing and planned preclinical studies and clinical studies, or any future preclinical studies or clinical studies, we may conduct of our current and any future product candidates, or changes in the development status of our current and any future product candidates;

● any delay in preparing regulatory submissions to support development or commercialization of our current and any future product candidates and any adverse development or perceived adverse development with respect to the applicable regulatory authority's review of such submissions, including without limitation the FDA's issuance of a "refusal to file" letter or a request for additional information;

● adverse results or delays in our preclinical studies and clinical studies;

[**Table of Contents**](#TOC)

● our decision to initiate a clinical trial, not to initiate a clinical trial, or to terminate an existing clinical trial;

● adverse regulatory decisions, including failure to receive marketing approval for our current and any future product candidates;

● changes in laws or regulations applicable to our current and any future product candidates, including but not limited to clinical trial requirements for approvals;

● the failure to obtain coverage and adequate reimbursement of our current and any future product candidates, if approved;

● changes on the structure of healthcare payment systems;

● any changes to our relationship with any manufacturers, suppliers, licensors, future collaborators or other strategic partners;

● our inability to obtain adequate product supply for any approved drug product or inability to do so at acceptable prices;

● our inability to establish collaborations if needed;

● our failure to commercialize our current and any future product candidates;

● additions or departures of key scientific or management personnel;

● unanticipated serious safety concerns related to the use of our current and any future product candidates;

● introduction of new products or services offered by us or our competitors, or the release or publication of clinical trial results from competing product candidates;

● announcements of significant acquisitions, strategic partnerships, joint ventures, or capital commitments by us or our competitors;

● our ability to effectively manage our growth;

● actual or anticipated variations in quarterly operating results;

● our cash position;

● our failure to meet the estimates and projections of the investment community or that we may otherwise provide to the public;

● publication of research reports about us or our industry or positive or negative recommendations or withdrawal of research coverage by securities analysts;

● changes in the market valuations of similar companies;

● overall performance of the equity markets;

● issuances of debt or equity securities;

● sales of our ADSs by us or our shareholders in the future, or the perception that such sales may occur;

● trading volume of our ADSs;

● changes in accounting practices;

● ineffectiveness of our internal controls;

● disputes or other developments relating to proprietary rights, including patents, litigation matters, and our ability to obtain patent protection for our technologies;

[**Table of Contents**](#TOC)

● significant lawsuits, including patent or shareholder litigation;

● general geopolitical and macroeconomic conditions, including as a result of bank failures, actual or threatened tariffs, global pandemics, and various global conflicts;

● other events or factors, many of which are beyond our control; and

● statements of belief and any statement of assumptions underlying any of the foregoing.

In addition, the stock market in general, and biopharmaceutical companies in particular, 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. In the past, securities class action litigation has often been instituted against companies following periods of volatility in the market price of a company's securities. This type of litigation, if instituted, could result in substantial costs and a diversion of management's attention and resources, which would harm our business, operating results or financial condition.

***Although our annual financial statements were audited and reported upon by auditors who are currently subject to inspection by the Public Company Accounting Oversight Board ("PCAOB"), there is no guarantee that future audit reports will be prepared by auditors that are subject to inspection by the PCAOB and, as such, future investors may be deprived of such inspections, which could result in limitations or restrictions to our access of the U.S. capital markets. Furthermore, trading in our securities may be prohibited under the Holding Foreign Companies Accountable Act ("HFCA Act") or the Accelerating Holding Foreign Companies Accountable Act ("AHFCA Act") if the SEC subsequently identifies that our audit work is performed by an auditor that the PCAOB is unable to inspect or investigate completely, and as a result, U.S. national securities exchanges, such as the Nasdaq, may delist our securities.***

As part of a continued regulatory focus in the United States on access to audit and other information, the United States passed the HFCA Act in December 2020. The HFCA Act requires the SEC to identify issuers whose audit work is performed by auditors that the PCAOB is unable to inspect or investigate completely because of a restriction imposed by a non-U.S. authority in the auditor's local jurisdiction. The HFCA Act also requires public companies identified by the SEC to certify that they are neither owned nor controlled by a foreign government, and make certain additional disclosures in their SEC filings.

The HFCA Act also provides that if an auditor of a U.S. listed company's financial statements is not subject for three consecutive "non-inspection years" after the HFCA Act becomes effective, the SEC must prohibit the securities of such issuer from being traded on a U.S. national securities exchange. However, in June 2021, the U.S. Senate passed the AHFCA Act which amends the HFCA Act and requires the SEC to prohibit an issuer's securities from trading on any U.S. stock exchanges if its auditor is subject to two "non-inspection years" instead of three. On February 4, 2022, the U.S. House of Representatives passed the America Creating Opportunities for Manufacturing, Pre-Eminence in Technology, and Economic Strength Act of 2022, which contained, among other things, an identical provision. In December 2021, the PCAOB issued a report on its determination that it is unable to inspect or investigate completely PCAOB-registered accounting firms headquartered in Mainland China and in Hong Kong. Also, in December 2021, the SEC adopted final amendments to its rules implementing the HFCA Act and established procedures to identify issuers and prohibit the trading of the securities of certain registrants as required by the HFCA Act. This rule stated that only the principal accountant, as defined by Rule 2-05 of Regulation S-X and PCAOB AS 1205, is "deemed 'retained' for purposes of Section 104(i) of the Sarbanes-Oxley Act and the SEC's determination of whether the registrant should be a Commission Identified Issuer." In December 2022, the PCAOB vacated its determination that it was unable to inspect and investigate PCAOB-registered public accounting firms in Mainland China and Hong Kong. As a result, until such time as the PCAOB issues a new determination, the SEC has determined that there are no issuers currently at risk of having their securities subject to a trading prohibition under the HFCA Act. However, while vacating those determinations, the PCAOB noted that,

[**Table of Contents**](#TOC)

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 issue a new determination.

Ernst & Young LLP, our independent registered public accounting firm is headquartered in the United States, is registered with the PCAOB and is an auditor of companies that are both registered with the SEC and publicly traded in the United States. As a result, the HFCA Act does not currently apply to us. However, if our operations fundamentally change in a way that requires our independent registered public accounting firm to be located in China in order to comply with the standards of the PCAOB regarding auditors then the HFCA Act would apply to us. Such a restriction would negatively impact our ability to raise capital. We view the likelihood to be remote that our operations will fundamentally change, as to require our auditor to be located in China. Additionally, it is possible that in the future Congress could amend the HFCA Act or the SEC could modify its regulations to apply the restrictions, including trading prohibitions and delisting, under the HFCA Act in situations in which an independent registered public accounting firm in China performs part of the audit such as in our current situation. There are currently no such proposals.

Further, while we understand that there has been dialogue among the CSRC, the SEC and the PCAOB regarding the inspection of PCAOB-registered accounting firms in China, there can be no assurance that, in the future, we will be able to comply with requirements imposed by U.S. regulators. The market price of our ADSs could be adversely affected as a result of anticipated negative impacts of these executive or legislative actions upon, as well as negative investor sentiment towards, companies with operations in China that are listed in the United States, regardless of whether these executive or legislative actions are implemented and regardless of our actual operating performance.

***We have identified material weaknesses in our internal control over financial reporting in the past and may identify additional material weaknesses in the future or fail to maintain effective internal control over financial reporting, which may result in material misstatements of our consolidated financial statements or cause us to fail to meet our periodic reporting obligations.***

We have previously identified material weaknesses in our internal control over financial reporting. 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.

We previously reported a material weakness in that we did not design and maintain an effective control environment commensurate with our financial reporting requirements as we lacked a sufficient complement of professionals commensurate with our financial reporting requirements. Additionally, the lack of a sufficient number of professionals resulted in an inability to consistently establish appropriate authorities and responsibilities in pursuit of our financial reporting objectives.

This material weakness did not result in any material misstatements to the consolidated financial statements. This material weakness could result in a misstatement of substantially all of our accounts or disclosures that would result in a material misstatement to the annual or interim consolidated financial statements that would not be prevented or detected. The material weakness was fully remediated as of June 30, 2024.

In the future we may determine that we have additional material weaknesses. Our failure to identify and address any other material weaknesses that may be identified in the future could result in material misstatements to our financial statements and could also impair our ability to comply with applicable financial reporting requirements and related regulatory filings on a timely basis, which could cause investors to lose confidence in our reported financial information, which may result in volatility in and a decline in the market price of our securities.

[**Table of Contents**](#TOC)

***Our principal shareholders and management own a significant percentage of our voting securities and will be able to exert significant control over matters subject to shareholder approval.***

As of September 30, 2025, our executive officers, directors, large shareholders and their affiliates beneficially owned approximately 41% of the voting power of our outstanding share capital (excluding the 39,000,000 ordinary shares issued to our depositary bank for bulk issuances of ADSs reserved for future issuances upon (i) the exercise or vesting of awards granted under our equity incentive plans, and upon (ii) the sale of ADSs pursuant to the ATM Sales Agreement). Therefore, these shareholders will have the ability to influence us through their ownership positions. These shareholders may be able to determine all matters requiring shareholder approval. For example, these shareholders, acting together, may be able to control elections of directors, issuances of equity, including to our employees under equity incentive plans, amendments of our organizational documents, or approval of any merger, amalgamation, sale of assets or other major corporate transaction. These shareholders' interests may not always coincide with our corporate interests or the interests of other shareholders, and these shareholders may exercise their voting and other rights in a manner with which you may not agree or that may not be in the best interests of our other shareholders. This may prevent or discourage unsolicited acquisition proposals or offers for our ADSs that you may believe are in your best interest as a holder of our ADSs.

***Substantial future sales of our ADSs could cause the market price of our ADSs to drop significantly, even if our business is doing well.***

Sales of a substantial number of our ADSs in the public market could occur at any time. If our shareholders sell, or the market perceives that our shareholders intend to sell, substantial amounts of our ADSs in the public market, the market price of our ADSs could decline significantly.

In the future we may issue ADSs or other securities if we need to raise additional capital and, in the event a large number of ADSs are sold in the public market, such sales could reduce the trading price of our ADSs.

Future issuances under certain employee equity benefit plans could result in a reduction in the market price of our ADSs. We have filed and intend to continue to file registration statements on Form S-8 under the Securities Act registering the issuance of additional ordinary shares (or ADSs), including because the number of shares that may be issued under certain employee equity benefit plans automatically increase as a result of the operation of certain "evergreen" provisions in our equity plans. Shares (or ADSs) registered under these registration statements are available for sale in the public market subject to vesting arrangements and exercise of options and, in the case of our affiliates, the restrictions of Rule 144 under the Securities Act. If these additional shares or ADSs are sold, or if it is perceived that they will be sold, in the public market, the trading price of our ADSs could decline.

In addition, on August 6, 2025, we entered into the ATM Sales Agreement with the ATM Sales Agents, pursuant to which we may, from time to time, offer and sell our ADSs up to an aggregate offering price of $250.0 million. During the three months ended September 30, 2025, we sold 3,040,000 ADSs under the ATM Sales Agreement, for gross proceeds of approximately $58.5 million. As of September 30, 2025, approximately $191.5 million remained available for sale under the ATM Sales Agreement.

***Holders of our ADSs have fewer rights than our shareholders and must act through the depositary to exercise their rights.***

Holders of our ADSs do not have the same rights as our shareholders and may only exercise their voting rights with respect to the underlying ordinary shares in accordance with the provisions of the deposit agreement. Holders of the ADSs will appoint the depositary or its nominee as their representative to exercise the voting rights attaching to the ordinary shares represented by the ADSs. When a general meeting is convened, if you hold ADSs, you may not receive sufficient notice of a shareholders' meeting to permit you to withdraw the ordinary shares underlying your ADSs to allow you to vote with respect to any specific matter. We will take all commercially reasonable efforts to cause the depositary to extend voting rights to you in a

[**Table of Contents**](#TOC)

timely manner, but we cannot assure you that you will receive voting materials in time to instruct the depositary to vote, and it is possible that you, or persons who hold their ADSs through brokers, dealers or other third parties, will not have the opportunity to exercise a right to vote. Furthermore, the depositary will not be liable for any failure to carry out any instructions to vote, for the manner in which any vote is cast or for the effect of any such vote. As a result, you may not be able to exercise your right to vote and you may lack recourse if your ADSs are not voted as you request. In addition, in your capacity as an ADS holder, you will not be able to call a shareholders' meeting.

***ADS 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 holders and beneficial owners of ADSs irrevocably waive the right to a trial by jury in any legal proceeding arising out of or relating to the deposit agreement, our ordinary shares or the ADSs or the transactions contemplated thereby, including claims under federal securities laws, against us or the depositary to the fullest extent permitted by applicable law. If this jury trial waiver provision is prohibited by applicable law, an action could nevertheless proceed under the terms of the deposit agreement with a jury trial. To our knowledge, the enforceability of a jury trial waiver under the federal securities laws has not been finally adjudicated by a federal court. However, we believe that a jury trial waiver provision is generally enforceable under the laws of the State of New York, which govern the deposit agreement, by a court of the State of New York or a federal court in New York, which have non-exclusive jurisdiction over matters arising under the deposit agreement, applying such law. In determining whether to enforce a jury trial waiver provision, New York courts and federal courts will consider whether the visibility of the jury trial waiver provision within the agreement is sufficiently prominent such that a party has knowingly waived any right to trial by jury. We believe that this is the case with respect to the deposit agreement, our ordinary shares and the ADSs and the transactions contemplated thereby. In addition, New York courts will not enforce a jury trial waiver provision in order to bar a viable setoff or counterclaim sounding in fraud or one which is based on a creditor's negligence in failing to liquidate collateral upon a guarantor's demand, or in the case of an intentional tort claim (as opposed to a contract dispute), none of which we believe are applicable in the case of the deposit agreement, our ordinary shares or the ADSs or the transactions contemplated thereby. 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 provision of the federal securities laws. If you or any other holder or beneficial owner of ADSs brings a claim against us or the depositary in connection with matters arising under the deposit agreement, our ordinary shares or the ADSs or the transactions contemplated thereby, you 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, which would be conducted according to different civil procedures and may augur different results than a trial by jury would have had, including results that could be less favorable to the plaintiff(s) in any such action, depending on, among other things, the nature of the claims, the judge or justice hearing such claims, and the venue of the hearing.

***You may not receive distributions on our ordinary shares represented by the ADSs or any value for them if it is illegal or impractical to make them available to holders of ADSs.***

Although we do not have any present plans to declare or pay any dividends on our ordinary shares, in the event we declare and pay any dividends, the depositary for the ADSs has agreed to pay to you 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. You will receive these distributions in proportion to the number of our ordinary shares your ADSs represent. However, in accordance with the limitations set forth in the deposit agreement, it may be unlawful or impractical to make a distribution available to holders of ADSs. We have no obligation to register under U.S. securities laws any offering of ADSs, ordinary shares or other securities received through such distributions. We also have no obligation to take any other action to permit distribution on the ADSs, ordinary shares, rights or anything else to holders of the ADSs. This means that you

[**Table of Contents**](#TOC)

may not receive the distributions we make on our ordinary shares or any value from them if it is unlawful or impractical to make them available to you. These restrictions may have an adverse effect on the value of your ADSs.

***Your right to participate in any future rights offerings may be limited, which may cause dilution to your 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 you in the United States unless we register the rights and the securities to which the rights relate under the Securities Act or an exemption from the registration requirements is available. Also, under the deposit agreement, the depositary bank will not make rights available to you unless the rights and any related securities are registered under the Securities Act or are otherwise exempted from registration under the Securities Act. We are under no obligation to file a registration statement with respect to any such rights or securities or to endeavor to cause such a registration statement to be declared effective. Moreover, we may not be able to establish an exemption from registration under the Securities Act. If the depositary does not distribute the rights, it may, under the deposit agreement, either sell them, if possible, or allow them to lapse. Accordingly, you may be unable to participate in our rights offerings and may experience dilution in your holdings.

***Because we do not anticipate paying any cash dividends on our ADSs in the foreseeable future, capital appreciation, if any, will be your sole source of gains and you may never receive a return on your investment.***

We have never declared or paid a dividend on our ordinary shares in the past, and we currently intend to retain our future earnings, if any, to fund the development and growth of our business. Therefore, you should not rely on an investment in our ADSs to provide dividend income. Our board of directors has complete discretion as to whether to distribute dividends, subject to certain restrictions under Cayman Islands law, including that our company may only pay dividends out of profits or out of the credit standing in our share premium account, and provided always that in no circumstances may a dividend be paid if it would result in our inability to pay our debts as they fall due in the ordinary course of business. In addition, our shareholders may, subject to our amended and restated memorandum and articles of association, by ordinary resolution declare a dividend, but no dividend may exceed the amount recommended by our board of directors. Even if our board of directors decides to declare and pay dividends, the timing, amount and form of future dividends, if any, will depend on, among other things, our future results of operations and cash flow, our capital requirements and surplus, the amount of distributions, if any, received by us from our subsidiaries, our financial condition, contractual restrictions and other factors deemed relevant by our board of directors. As a result, capital appreciation, if any, on our ADSs will be your sole source of gains for the foreseeable future.

#### We are subject to tax in the Cayman Islands and the United States.
We are a Cayman Islands corporation as of the date of this Quarterly Report. We are treated as an exempted company for Cayman Islands tax purposes. We are also treated as a U.S. corporation subject to U.S. federal income tax pursuant to Section 7874 of the Code, and are subject to U.S. federal income tax on our worldwide income. As a result, we are subject to tax both in the Cayman Islands and the United States, which could have a material adverse effect on our financial condition and results of operations.

It is unlikely that we will pay any dividends on our ordinary shares or ADSs in the foreseeable future. However, dividends received by "non-U.S. holders" will be subject to U.S. withholding tax. In addition, because the ordinary shares or ADSs are treated as shares of a U.S. domestic corporation, the U.S. gift, estate and generation-skipping transfer tax rules generally apply to a non-U.S. holder of ordinary shares or ADSs.

Each holder or prospective holder of our ordinary shares or ADSs should seek tax advice from an independent tax advisor based on such holder's particular circumstances.

[**Table of Contents**](#TOC)

***Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.***

As of December 31, 2024, we had $99.2 million and $147.8 million of U.S. federal and state net operating loss ("NOL") carryforwards, respectively, available to offset future taxable income. Under U.S. federal income tax law, federal NOLs incurred in tax years beginning after December 31, 2017, may be carried forward indefinitely, but the deductibility of such federal NOLs is limited to 80% of taxable income for taxable years beginning after December 31, 2020. Any NOLs incurred in tax years beginning before December 31, 2017, may be used to offset up to 100% of future taxable income, but will begin to expire in varying amounts in 2036, unless previously utilized. Similar rules may apply under state tax laws. As of December 31, 2024, we also had aggregate U.S. federal and state R&D credits of approximately $5.7 million and $1.3 million, respectively. U.S. federal R&D credits carryforwards begin to expire in 2039 unless previously utilized. The state R&D credit carryforwards do not expire. Our NOL carryforwards and R&D credits are subject to review and possible adjustment by the U.S. and state tax authorities.

In addition, under Sections 382 and 383 of the Code, and corresponding provisions of state law, if a corporation undergoes an "ownership change," which is generally defined as a greater than 50 percentage point change (by value) in its equity ownership over a three-year period, the corporation's ability to use its pre-change NOL carryforwards, R&D credits and certain other tax attributes to offset its post-change income or taxes may be limited. This could limit the amount of NOLs, R&D credit carryforwards or other applicable tax attributes that we can utilize annually to offset future taxable income or tax liabilities. Subsequent ownership changes and changes to the U.S. tax rules in respect of the utilization of NOLs, R&D credits and other applicable tax attributes carried forward may further affect the limitation in future years. In addition, at the state level, there may be periods during which the use of NOLs is suspended or otherwise limited, which could accelerate or permanently increase state taxes owed. As a result, we may be unable to use all or a material portion of our NOL carryforwards and other tax attributes, which could adversely affect our future cash flows. We have not undertaken a study under Section 382 of the Code, and it is possible that we have previously undergone one or more ownership changes so that our use of NOLs is subject to limitation. We may experience ownership changes in the future as a result of subsequent shifts in our share ownership. As a result, if we earn net taxable income, our ability to use our pre-change NOLs to offset U.S. federal taxable income may be subject to limitations, which could potentially result in increased future tax liability to us. At the state level, California has suspended the use of NOLs by certain taxpayers for tax years beginning on or after January 1, 2024, and before January 1, 2027. Other states may also suspend or otherwise place limitations on the use of NOLs, which could accelerate or permanently increase state taxes owed.

***We will incur significantly increased costs as a result of operating as a company whose ADSs are publicly traded in the United States, and our management will be required to devote substantial time to new compliance initiatives.***

As a public company in the United States, we will incur significant legal, accounting and other expenses that we did not incur prior to our IPO. These expenses will likely be even more significant in the future since we no longer qualify as an emerging growth company as of December 31, 2024. We are subject to the reporting requirements of the Exchange Act, which require, among other things, that we file with the SEC annual, quarterly and current reports with respect to our business and financial condition. In addition, the Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act, the listing requirements of Nasdaq and other applicable securities rules and regulations impose various requirements on public companies in the United States, including the establishment and maintenance of effective disclosure and financial controls and corporate governance practices. Our senior management and other personnel will need to devote a substantial amount of time to these compliance initiatives. Moreover, these rules and regulations will increase our legal and financial compliance costs and will make some activities more time-consuming and costly. For example, we expect that these rules and regulations may make it more difficult and more expensive for us to obtain director and officer liability insurance, which in turn could make it more difficult for us to attract and retain qualified senior management personnel or members for our board of directors.

[**Table of Contents**](#TOC)

However, these rules and regulations are often subject to varying interpretations, in many cases due to their lack of specificity, and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. This could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices.

Pursuant to Section 404 of the Sarbanes-Oxley Act, we are required to furnish a report by our senior management on our internal control over financial reporting. Additionally, beginning with our Annual Report on Form 10-K for the year ended December 31, 2024, we are required to include an attestation report on internal control over financial reporting issued by our independent registered public accounting firm. To prepare for compliance with Section 404, we engaged in a process to document and evaluate our internal control over financial reporting, which is both costly and challenging. In this regard, we have dedicated internal resources, engaged outside consultants and adopted a detailed work plan to assess and document the adequacy of internal control over financial reporting. We will continue to incur increasing costs with regards to compliance with Section 404 in the future.

***Since shareholder rights under Cayman Islands law differ from those under U.S. law, you may have difficulty protecting your shareholder rights.***

We are an exempted company limited by shares incorporated under the laws of the Cayman Islands. Our corporate affairs are governed by our amended and restated memorandum and articles of association, the Companies Act (as amended) of the Cayman Islands 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 responsibilities 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 responsibilities 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, Cayman Islands companies may not have standing to initiate a shareholder derivative action in a federal court of the United States.

Shareholders of Cayman Islands exempted companies like us have no general rights under Cayman Islands law to inspect corporate records, other than the amended and restated memorandum and articles of association and any special resolutions passed by such companies, and the registers of mortgages and charges of such companies. The Registrar of Companies of the Cayman Islands shall make available the list of the names of our current directors (and where applicable the current alternate directors of the Company) for inspection by any person upon payment of a fee by such person. Our directors have discretion under our amended and restated memorandum and 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 you 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.

Certain corporate governance practices in the Cayman Islands, which is our home country, differ significantly from requirements for companies incorporated in other jurisdictions such as the United States. Currently, we do not plan to rely on home country practice with respect to any corporate governance matter. However, if we choose to follow home country practice in the future, our shareholders may be afforded less protection than they otherwise would under rules and regulations applicable to U.S. domestic issuers.

As a result of all of the above, public shareholders may have more difficulty in protecting their interests in the face of actions taken by our management, members of our board of directors or our controlling shareholders than they would as public shareholders of a company incorporated in the United States.

[**Table of Contents**](#TOC)

***Provisions in our amended and restated memorandum and articles of association may prevent or frustrate attempts by our shareholders to change our management and hinder efforts to acquire a controlling interest in us, and the market price of our ADSs may be lower as a result.***

There are provisions in our amended and restated memorandum and articles of association that may make it difficult for a third party to acquire, or attempt to acquire, control of our company, even if a change of control was considered favorable by you and other shareholders. For example, as of the date of this Quarterly Report, our board of directors will have the authority to issue up to 100,000,000 shares of an additional class or classes of shares, which could include preference shares. The board of directors can fix the price, rights, preferences, privileges, and restrictions of the other classes of shares without any further vote or action by our shareholders. The issuance of such shares may delay or prevent a change of control transaction. As a result, the market price of our ADSs and the voting and other rights of our shareholders may be adversely affected. An issuance of other classes of shares may result in the loss of voting control to other shareholders.

Our charter documents will also contain other provisions that could have an anti-takeover effect, including:

● only one of our three classes of directors will be elected each year;

● shareholders will be entitled to remove directors only for cause;

● shareholders will not be permitted to take actions by written consent; and

● shareholders must give advance notice to nominate directors or submit proposals for consideration at annual general meetings.

These provisions could discourage potential acquisition proposals and could delay or prevent a change of control transaction. They could also have the effect of discouraging others from making tender offers, including transactions that may be in your best interests. These provisions may also prevent changes in our management or limit the price that investors are willing to pay for our ADSs.

#### You may be subject to limitations on transfers of your ADSs.
Your 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 deemed necessary or advisable by it in good faith in connection with the performance of its duties or at our reasonable written request, subject in all cases to compliance with applicable U.S. securities laws. 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.

#### General Risk Factors
***Failure to build our finance infrastructure and improve our accounting systems and controls could impair our ability to comply with the financial reporting and internal controls requirements for publicly-traded companies.***

As a public company, we operate in an increasingly demanding regulatory environment, which requires us to comply with the Sarbanes-Oxley Act, the regulations of Nasdaq, the rules and regulations of the SEC, expanded disclosure requirements, accelerated reporting requirements and more complex accounting rules. Company responsibilities required by the Sarbanes-Oxley Act include establishing corporate oversight and adequate internal control over financial reporting and disclosure controls and procedures. Effective internal controls are necessary for us to produce reliable financial reports and are important to help prevent financial fraud. We must perform system and process evaluation and testing of our internal control over financial reporting to allow management to report on the effectiveness of our internal control over financial reporting in our Annual Report on Form 10-K, as required by Section 404 of the Sarbanes-Oxley Act. Prior to our IPO, we

[**Table of Contents**](#TOC)

had never been required to test our internal controls within a specified period and, as a result, we may experience difficulty in meeting these reporting requirements in a timely manner. In addition, our independent registered public accounting firm is required to attest to the effectiveness of our internal control over financial reporting beginning with our Annual Report on Form 10-K for the year ended December 31, 2024.

We anticipate that the process of building our accounting and financial functions and infrastructure will require significant additional professional fees, internal costs and management efforts. We expect that we will need to implement a new internal system to combine and streamline the management of our financial, accounting, human resources and other functions. However, such a system would likely require us to complete many processes and procedures for the effective use of the system or to run our business using the system, which may result in substantial costs. Any disruptions or difficulties in implementing or using such a system could adversely affect our controls and harm our business. Moreover, such disruption or difficulties could result in unanticipated costs and diversion of management attention. In addition, we may discover weaknesses in our system of internal financial and accounting controls and procedures that could result in a material misstatement of our financial statements. Our internal control over financial reporting will not 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. 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 will be detected.

If we are unable to maintain proper and effective internal controls, we may not be able to produce timely and accurate financial statements. If we cannot provide reliable financial reports or prevent fraud, our business and results of operations could be harmed, investors could lose confidence in our reported financial information, the market price of our ADSs could decline and we could be subject to sanctions or investigations by Nasdaq, the SEC or other regulatory authorities. Failure to remedy any material weakness in our internal control over financial reporting, or to implement or maintain other effective control systems required of public companies, could also restrict our future access to the capital markets.

***If we are unable to maintain effective internal controls, our business, financial position and results of operations could be adversely affected.***

As a public company, we are subject to the requirements of Section 404 of the Sarbanes-Oxley Act, which require annual management assessments of the effectiveness of our internal control over financial reporting. In addition, our independent registered public accounting firm is required to attest to the effectiveness of our internal control over financial reporting beginning with our Annual Report on Form 10-K for the year ended December 31, 2024.

The rules governing the standards that must be met for management to determine that our internal control over financial reporting is effective are complex and require significant documentation, testing and possible remediation to meet the detailed standards under the rules. During the course of its testing, our management has in the past and may in the future identify material weaknesses or deficiencies. For example, we have previously identified material weaknesses in our internal control over financial reporting in the past, which we reported to have been fully remediated as of June 30, 2024. These reporting and other obligations place significant demands on our management and administrative and operational resources, including accounting resources.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Our 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 accounting principles generally accepted in the United States. If we identify any future material weaknesses and are unable to remediate such material weakness and conclude that our internal control over financial reporting is effective, or if in the future our independent registered public accounting firm determines we have a material weakness in our internal control over financial reporting, this could have an adverse effect on our business, financial position and results of operations.

[**Table of Contents**](#TOC)

#### Our disclosure controls and procedures may not prevent or detect all errors or acts of fraud.
We are subject to the periodic reporting requirements of the Exchange Act. We designed our disclosure controls and procedures to reasonably ensure that information we must disclose in reports we file or submit pursuant to the Exchange Act is accumulated and communicated to management, and recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. We believe that any disclosure controls and procedures, or internal controls and procedures, no matter how well-conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met.

These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. For example, our directors or executive officers could inadvertently fail to disclose a new relationship or arrangement causing us to fail to make any related party transaction disclosures. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by an unauthorized override of the controls. Accordingly, because of the inherent limitations in our control system, misstatements due to error or fraud may occur and not be detected.

***Future changes in financial accounting standards or practices may cause adverse and unexpected revenue fluctuations and adversely affect our reported results of operations.***

Future changes in financial accounting standards may cause adverse, unexpected revenue fluctuations and affect our reported financial position or results of operations. Financial accounting standards in the United States are constantly under review and new pronouncements and varying interpretations of pronouncements have occurred with frequency in the past and are expected to occur again in the future. As a result, we may be required to make changes in our accounting policies. Those changes could affect our financial condition and results of operations or the way in which such financial condition and results of operations are reported. We intend to invest resources to comply with evolving standards, and this investment may result in increased general and administrative expenses and a diversion of management time and attention from business activities to compliance activities.

***If equity research analysts do not publish research or reports, or publish unfavorable research or reports, about us, our business or our market, the price and trading volume of our ADSs could decline.***

The trading market for our ADSs will be influenced by the research and reports that equity research analysts publish about us and our business. We do not currently have and may never obtain research coverage by equity research analysts. Equity research analysts may elect not to provide research coverage of our ADSs, and such lack of research coverage may adversely affect the market price of our ADSs. In the event we do have equity research analyst coverage, we will not have any control over the analysts or the content and opinions included in their reports. The price of our ADSs could decline if one or more equity research analysts downgrade our ADSs or issue other unfavorable commentary or research about us. If one or more equity research analysts cease coverage of us or fail to publish reports on us regularly, demand for our ADSs could decrease, which in turn could cause the trading price or trading volume of our ADSs to decline.

#### We could be subject to securities class action litigation or material legal proceedings which could have a negative impact on our reputation or business.
In the past, securities class action litigation has often been brought against a company following a decline in the market price of its securities. This risk is especially relevant for us because pharmaceutical companies have experienced significant stock price volatility in recent years. If we face such litigation, it could result in substantial costs and a diversion of management's attention and resources, which could harm our business. In addition, from time to time, we are and may in the future be involved in legal and regulatory proceedings or investigations concerning matters that arise in the ordinary course of our business. Such proceedings could

[**Table of Contents**](#TOC)

result in significant fines or penalties, have an adverse impact on our reputation, business and financial condition or results or operations and divert the attention of our management from the operation of our business.

***We or the third parties upon whom we depend may be adversely affected by earthquakes, fires or other natural disasters and our business continuity and disaster recovery plans may not adequately protect us from a serious disaster.***

Our headquarters and main research facility are located near San Francisco, California, which in the past has experienced severe earthquakes and fires. If these earthquakes, fires, other natural disasters, terrorism and similar unforeseen events beyond our control prevented us from using all or a significant portion of our headquarters or research facility, it may be difficult or, in certain cases, impossible for us to continue our business for a substantial period of time. We do not have a disaster recovery or business continuity plan in place and may incur substantial expenses as a result of the absence or limited nature of our internal or third-party service provider disaster recovery and business continuity plans, which, particularly when taken together with our lack of earthquake insurance, could have a material adverse effect on our business. Furthermore, integral parties in our supply chain are operating from single sites, increasing their vulnerability to natural disasters or other sudden, unforeseen and severe adverse events. If such an event were to affect our supply chain, it could have a material adverse effect on our ability to conduct our clinical studies, our development plans and business.

***If we 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 the third parties with whom we share our facilities, 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. Each of our operations involve the use of hazardous and flammable materials, including chemicals and biological and radioactive materials. Each of 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. We could be held liable for any resulting damages in the event of contamination or injury resulting from the use of hazardous materials by us or the third parties with whom we share our facilities, 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 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 or disposal of biological, hazardous or radioactive materials.

In addition, we may incur substantial costs in order to comply with current or future environmental, health and safety laws and regulations. These current or future laws and regulations may impair our research and development. Failure to comply with these laws and regulations also may result in substantial fines, penalties or other sanctions.

***Our failure to meet Nasdaq's continued listing requirements could result in a delisting of our ADSs.***

If we fail to satisfy the continued listing requirements of Nasdaq, such as the corporate governance requirements or the minimum closing bid price requirement, Nasdaq may take steps to delist our ADSs. Such a delisting would likely have a negative effect on the price of our ADSs and would impair your ability to sell or purchase our ADSs when you wish to do so. In the event of a delisting, any action taken by us to restore compliance with listing requirements may not allow our ADSs to become listed again, stabilize the market

[**Table of Contents**](#TOC)

price or improve the liquidity of our ADSs, prevent our ADSs from dropping below the Nasdaq minimum bid price requirement or prevent future non-compliance with the listing requirements of Nasdaq.

**Item 2. Unregistered Sales of Equity Securities and Use of Proceeds**

We did not have any unregistered sales of equity securities during the three months ended September 30, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**1.** **CONTRACT TERM** 

合同期限

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.1. This Contract shall be an open-ended employment contract. The employment under this Contract shall commence on July 22, 2025 (the "**Commencement Date**") and shall continue in full force until terminated by either Party in accordance with the terms of this contract.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.1. The Employee will hold the position of Chief Scientific Officer & General Manager, China.

The Employee agrees that the Company may reasonably transfer the Employee to a different job position on a temporary or permanent basis pursuant to its business or operational requirements and in line with the Employee's professional, technical or physical abilities and work performance.

雇员将担任首席科学官兼中国区总经理。雇员将从事本合同<u>附件</u><u>A</u> 工作说明中所述的工作。雇员同意，公司可根据其业务或经营需要，以及雇员的专业、技术能力或身体条件和工作表现，合理地将雇员临时性或永久性地调整到另一工作岗位。

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.2. The Employee will perform all duties hereunder in good faith and to the best of the Employee's ability. The Employee agrees to devote all working time, attention and energies to the business of the Company and to be available at all reasonable times to perform such work as the Company may require. The Employee may not in any way act against the interests of the Company. The Employee shall always conduct himself in the best interest of the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.3. The Employee will primarily be based in Shanghai, but will engage in travel as part of the Employee's work.

雇员的主要工作地点为上海，但作为其工作一部分，雇员将会出差。

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.4. The Employee hereby agrees that the Company may arrange for the Employee to work from home or at the Company's office site, depending on factors such as the Company's business needs and the characteristics of the Employee's job position and function. If the Employee is arranged to mainly work at home, the Company may request the Employee to go to the office to attend meetings, report to the Employee's supervisor or handle other assignments or business at any time and the Company reserves the right to change the Employee's main work site.

雇员特此同意，取决于公司业务需要、雇员的岗位职责特点等因素，公司可以安排雇员在家办公或到公司的办公场所上班。如雇员被安排大部分时间在家办公，公司可随时要求雇员到公司办公室参加会议，向上级汇报工作或处理其他工作或业务，并且公司保留变更雇员主要工作场所的权利。

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.5. The Company may, within reason, reassign the Employee to another branch office or liaison office of the Company, or temporarily second the Employee to other locations, in accordance with business needs and to the extent permissible by law. The Employee may also be required and hereby agrees to travel to such places (whether within or outside the PRC) and in such manner and on such occasions as the Company may from time to time designate, or attend such training (either in the PRC or elsewhere) as the Company may determine.

公司可以根据业务需要及在法律允许的范围内合理地将雇员派往公司其他分支机构或办事处，或者将雇员临时派往其他办公地点履行工作。同时，雇员特此同意，其将按照公司的要求及公司不时指定的方式和情形前往公司指定的地点（无论中国境内或境

------

外）出差，或者根据公司的决定参加位于中国境内或境外的培训。

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.** **REMUNERATION AND SOCIAL INSURANCE** 

薪酬和社会保险

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.1. The Employee's annual base pay is ¥3,669,968.00 before the deduction of payable tax and the Employee's portion of social insurance, housing fund and other required contributions, if any. The Company may adjust the Employee's annual base pay as it implements new wage systems or adjusts wage levels. The Employee will be paid twelve (12) monthly pays for each calendar year.

雇员的年基本工资在扣除应纳税款以及雇员所须缴纳的社会保险、住房公积金和其他费用（如有）之前为 ¥3,669,968.00元。如公司实施新的工资制度或调整工资水平，公司可对雇员的年基本工资进行调整。雇员每一自然年发十二个月的工资。

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.2. The Company operates a discretionary bonus structure to reward and incentivize employees. The Employee may be considered eligible for bonus in accordance with this structure. The Employee will only be eligible to receive a bonus if the Employee satisfies the criteria of any bonus plan under the Company's bonus structure. The decision whether to pay a bonus, its amount, and the timing of payment (if any) shall be at the absolute discretion of the Company and conditioned upon satisfactory achievement of performance objectives set for the Employee by the Company. The Company may in its sole discretion elect to pay to the Employee variable and non-recurrent bonus in accordance with the Company's compensation policy, at an annual target amount equal to 40% of the Employee's base pay, provided that the amount of any discretionary bonus awarded to Employee for calendar year shall be prorated based on the actual number of days that the Employee works for the Company during calendar year 2025. The Employee will only be eligible to be considered for a bonus if the Employee is still employed by the Company and not within any period of notice of termination on the payment date, as the primary purpose of the bonus is to incentivize the Employee to remain with the Company. Receipt of a bonus in one year is not a guarantee of future bonus or similar bonus amount.

公司通过一项酌情性奖金结构来奖励和激励雇员。按照该结构，雇员可能被视为有资格获得奖金。雇员只有在满足公司奖金结构下制定的奖金计划要求的前提下才有资格获得奖金。是否支付奖金、奖金金额及奖金的支付时间（如有）， 应完全按雇员是否满意完成公司制定的雇员表现目标而由公司自行决定。公司经自行决定，可按照公司的薪酬政策向雇员支付可变的、非经常性的年度标准为雇员基本工资 <sup>40%</sup> 的奖金，但雇员在2025年自然年度所获得的任何酌情性奖金会根据雇员在 2025 自然年度在公司实际工作的天数按比例计算。因为奖金主要为鼓励雇员留在公司，只有在支付日仍受雇于公司并且未处于任何离职通知期内的雇员才被视为有资格获得奖金。某一年获得奖金，并不保证将来一定会获得奖金或类似的奖金金额。

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.3. The Company will withhold individual income tax and the Employee's portion of social insurance, housing fund and any other required contributions from the Employee's remuneration as required by PRC laws and regulations. The Company will, in accordance with applicable laws and regulations, pay the social insurance and housing fund contributions that it is required to bear.

公司将根据中国法律法规，从雇员的薪酬中代扣代缴个人所得税和雇员所须缴纳的社会保险、住房公积金和其他费用。公司将根据相关法律法规缴纳公司应承担的社会保险和住房公积金费用。

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.4. The Company may utilize a third party agency to handle payroll matters.

------

公司可使用第三方代理机构办理薪酬事宜。

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.5. The Company will reimburse reasonable business expenses incurred by the Employee in relation to work performed. Such expenses must be directly and solely in relation to work performed for and on behalf of the Company, and should be necessary in order to complete the Employee's job duties. Such reimbursements are subject to the Employee providing relevant receipts or invoices documenting the expenses incurred, with brief explanation of the reason for such expenses.

公司将报销雇员因工作而产生的合理业务支出。该等支出必须直接且仅因为公司及代表公司工作而产生，并且应为完成雇员的工作职责所必需的。该等报销的前提是雇员必须提供相关收据或发票证明所发生的费用并简要说明发生费用的理由。

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**5.** **WORK CONDITIONS, WORKING HOURS AND LEAVE** 

工作条件、工作时间和休假

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.1. The Company will provide the Employee with work conditions, labour protection, and protection against occupational hazards that conform to PRC laws and regulations.

公司应向雇员提供符合中国法律法规的工作条件、劳动保护和职业危害防护措施。

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.2. The Employee will be entitled to fifteen (15) days annual leave, plus all national holidays in the PRC in each calendar year. Annual leave entitlement will be prorated in accordance with actual working period in such calendar year. The Employee shall take the whole of his/her annual leave entitlement in respect of a calendar year within such calendar year. If this is not possible due to working reasons, the Employee may, with the written approval of his/her immediate supervisor or the legal representative of the Company, take deferred annual leave in the following calendar year.

雇员每公历年度将享有十五天年假以及中国境内的法定节假日。可休年假的天数应根据当年实际在职期间按比例计算。雇员应在当年休完该日历年内的所有年假。如果因工作原因无法休假的，经其直属领导或公司法定代表书面批准，雇员可在下个日历年内补休。

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.3. The Employee is subject to standard working hours system. Standard working hours during the workdays are from 9:00 am to 6:00 pm, Monday to Friday, and the lunch break is one (1) hour per day. The Company's hours of work shall not exceed eight (8) hours per day or forty-four (44) hours per week. The Employee shall devote sufficient time to his/her work and finish all his/her work properly and promptly.

If the Employee's position has already been approved to work under a working hours system different from the standard working hours system or if the Company in the future obtains such approval, the Employee hereby agrees to automatically be subject to that alternative working hours system. The Employee hereby agrees to provide any assistance necessary for and fully cooperate with the Company in its application for the Employee to work under the alternative working hours system. If no such approval is obtained, the Employee shall work overtime only if the Employee is so instructed by the supervising manager or the Employee obtains written approval from the supervising manager to work overtime.

雇员适用标准工时制。标准工作时间为周一至周五上午九点钟到下午六点钟，午餐时 间每天一个小时。每日工作时间不超过八小时，平均每周工作时间不超过四十四小时。雇员应保证充分的工作时间从而确保所有工作得以适当并及时完成。

如雇员的岗位已获批准按照非标准工时制工作，或公司将来获得该等批准，则雇员特 此同意，其将自动适用该等非标准工时制。雇员特此同意，当公司为雇员申请实施非标准工时制时，雇员将给予公司任何必要的协助并全力配合公司。如未获得该等批准，雇员只应在上级经理的要求时或事先获得上级经理书面批准的情况下才能履行加班工作。

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.4. If the Employee needs more than three (3) day's leave because of illness or a non-work related injury, the Employee must provide the Company with a written note, letter, certificate or other form of written documentation from a qualified licensed doctor of a public hospital as evidence of the Employee's non-work-related illness or injury.

------

如由于非因工患病或负伤，雇员需请假 3 天以上，必须向公司提交具备资质的公立医院的注册医生出具的书面通知、信函、证明或其他形式的书面文件，以证明该等非因工患病或负伤。

The Company has the right to require the Employee to provide any other reasonable relevant supporting medical documents (such as medical records, hospital registration, receipts, and invoices) or to undergo a second medical check with another hospital designated by the Company at the expense of the Company (and the Company can designate a HR personnel or another member of the Company to accompany the Employee to go through the second medical check). In case of discrepancy, the written note, letter, certificate or other type of written documentation from the Company-appointed hospital shall serve as the final evidence of the Employee's non-work-related illness or injury. If the Employee fails to provide such written evidence to the Company or refuses to submit to a medical examination by a Company appointed hospital or refuses to be accompanied by a colleague to conduct the second medical check, any leave taken will not be recognized by the Company and will be considered an unexcused leave of absence, for which the Company will deduct from the Employee's monthly base pay an amount proportional to the unexcused leave taken, or deducted from the Employee's annual leave entitlement and, if the annual leave entitlement for the year has already been completely used, then a proportional deduction will be made from the Employee's monthly base pay.

公司有权要求雇员提供任何其他合理的相关医疗证明文件（如病历卡、医院挂号单、收据和发票等）或在公司指定并付费的另一注册家医生院进行的第二次体检（公司可指定人事工作人员或公司其他人员陪同雇员进行第二次体检）。如体检结果不一致，应以公司指定的医院出具的书面通知、信函、证明或其他形式的书面文件作为雇员非因工患病或负伤的最终证据。如雇员未向公司提供该等书面证据，或拒绝由公司指定的医院进行体检或拒绝公司指派同事陪同进行第二次体检，则此等请假公司将不予认可，并将被视为无故旷工，公司将从雇员的月基本工资中按比例扣除与无故旷工时间相应的薪金或者从雇员的年假中予以扣除；如当年年假已全部休完，则从雇员的月基本工资中按比例扣除。

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.5. During the statutory medical treatment period, the Employee's sick leave pay shall be paid at the minimum rate allowed under applicable laws and regulations, unless the Company's rules and regulations provide otherwise.

在法定的医疗期内，雇员的病假工资应按相关法律法规允许的最低标准支付，除非公司规章制度另有规定。

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**6.** **PERSONAL CONDUCT, BEHAVIOR AND DISCIPLINE** 

个人行为和纪律

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.1. The Employee hereby confirms receipt of a copy of the Company's applicable rules and policies. If the Employee has not received a copy of such rules and policies then the Employee shall immediately obtain a copy from the Company's Human Resources department.

雇员特此确认已收到公司的适用规定和政策。如雇员尚未收到，雇员应立即从公司人力资源部获取该等规定和政策。

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.2. The Employee agrees to observe and comply with all rules, regulations, trade clearance policy, procedural practices and arrangements of the Company (specified in the Employee Handbook) and in other labor rules and regulations of the Company (collectively, the "**Employee Rules**") as they

------

may be amended (whether by way of internal memorandum or otherwise) from time to time. The Employee shall be required to sign acknowledgement of the terms and conditions in the Employee Handbook and Employee Rules on the Commencement Date or (if the Employee Handbook and/or Employee Rules are not in existence on the Commencement Date) on the date of adoption by Company of its initial Employee Handbook and Employee Rules. The Company may reward and discipline the Employee in accordance with such rules and regulations.

considered as "being unable to engage in the Employee's original work or in other work arranged by the employer".

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.5. If there is a major change in the objective circumstances upon which this Contract is concluded causing the Contract to no longer be performable as originally intended, then, to make the Contract performable, the Company may in its discretion offer the Employee either: (a) an existing alternative job (if an appropriate alternative job is available which may be at a different level of seniority and/or pay); or (b) putting the Employee on leave of absence and paying a basic living allowance (instead of full salary), which will be equal to the statutory local minimum wage in the location where the Contract is performed. If the Employee refuses the aforesaid offer or does not respond within fifteen 15 calendar days after receipt of the offer, then the Parties will be deemed to have failed to reach an agreement on amending the Contract to make it performable, and the Company may terminate this Contract.

如本合同订立时所依据的客观情况发生重大变化，致使本合同无法按原订立合同时的意图履行，则为使本合同得以履行，公司可酌情向雇员提供：(a)现有的其他岗位（如有合适的其他岗位，但该岗位的级别和/或工资可能不同于原岗位）；或(b)安排雇员放假并向雇员支付基本生活费（代替其全额工资），该基本生活费的金额将相当于本合同履行地的当地法定最低工资。如雇员拒绝上述任何提议， 或在收到提议后－15 个日历日

The Employee will only receive base pay (as stated in Article 3.1 of this Contract) and statutory benefits during any period of leave; all other additional compensation and benefits including but not limited to any bonus and commission will not accrue in relation to the leave period.

公司有权在本合同期限内(包括在任何通知期内)随时要求雇员不上班或不履行其任何工作职责，并且可在对雇员的违纪或违法行为进行调查期间暂停雇员的工作。如雇员被要求不上班，则该不上班期间应首先被视为安排雇员休年假。雇员在该等休假期间将仅获得基本工资（如本合同第 3.1 条所述）及法定福利；就该等休假期而言，所有其他额外报酬和福利（包括但不限于任何奖金和佣金）均不予计发。

The Employee hereby irrevocably waives any claim against the Company for any other reward or remuneration for any Inventions, regardless of whether the Company implements or licenses such Inventions or whether the Company makes any profit or receives any royalty payment or license fees from such Inventions. The Employee hereby also irrevocably waives any residual rights (including but not limited to the right of first refusal under the PRC Civil Code) to the Inventions that the Employee may have when the Company sells, transfers or otherwise disposes of the Inventions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. 不竞争义务

During the Non-Compete Period, the Employee shall continue to perform the non-compete obligations hereunder, and the Company agrees to pay compensations to the Employees on a monthly basis in an amount mutually agreed by parties. The Employee agrees that the compensation is sufficient and reasonable. Notwithstanding the foregoing, the Employee hereby agrees that the Company shall have the right to decide in its sole disrection to exempt the Employee from the non-compete obligations at any time and pay any statutory required minimum compensation for non-compete to the Employee.

5.不招揽义务

The Employee agrees that during his employment with the Company and for three (3) years following termination of his employment for any reason, he or she will not either for the Employee himself/herself or for any other person or entity (i) directly or indirectly, or attempt to solicit, induce, recruit or encourage any of the Company's employees to leave their employment, or take away such employees; or (ii) directly or indirectly solicit the business of any client or customer of the Company (other than on behalf of the Company), or directly or indirectly induce or influence the client or customer of the Company for them to restrict or cancel the business relationship with the Company. The Employee hereby agrees that the Company is not obligated to pay additional consideration for this non-solicitation obligation.

6.违约救济

Remedies for Violation

雇员特此确认，本协议规定的雇员的义务对于保护公司的合法利益是合理且必要的。如

B - 8

## Exhibit 10.2

**Exhibit 10.2**

***Tier I/Tier II***

**Appendix A**

**Participation Agreement**

**Name:**<u>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</u> 

**Section 1.** **Eligibility.**

You have been designated as eligible to participate in the Structure Therapeutics Inc. Severance and Change in Control Plan (the "***Plan***"), a copy of which is attached to this Participation Agreement (this "***Participation Agreement***"). Capitalized terms not explicitly defined in this Participation Agreement but defined in the Plan shall have the same definitions as in the Plan. You will receive the benefits set forth below if you meet all the eligibility requirements set forth in the Plan, including, without limitation, executing the required Release within the applicable time period set forth therein and allowing such Release to become effective in accordance with its terms. Notwithstanding the schedule for provision of benefits as set forth below, the schedule and timing of payment of any benefits under this Participant Agreement is subject to any delay in payment that may be required under Section 5 of the Plan.

**Section 2.** **Change in Control Severance Benefits.**

If you are terminated in a Covered Termination that occurs during the Change in Control Period, you will receive the severance benefits set forth in this Section 2. All severance benefits described herein are subject to standard deductions and withholdings.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(a)** **Base Salary.** You shall receive a cash payment in an amount equal to [<u>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</u> ]<sup>1</sup> months (the "***Severance Period***") of payment of your Base Salary. The Base Salary payment will be paid to you in a lump sum cash payment no later than the second regular payroll date following the later of (i) the effective date of the Release or (ii) the Closing, but in any event not later than March 15 of the year following the year in which your Separation from Service occurs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(b)** **Bonus Payment.** You will be entitled to [<u>&nbsp;&nbsp;&nbsp;&nbsp;</u> ]<sup>2</sup> of the annual target cash bonus established for you, if any, pursuant to the annual performance bonus or annual variable compensation plan established by the Committee (or any authorized committee or designee thereof) for the year in which your Covered Termination occurs. If at the time of the Covered Termination you are eligible for the annual target cash bonus for the year in which the Covered Termination occurs, but the target percentage (or target dollar amount, if specified as such in the applicable bonus plan) for such bonus has not yet been established for such year, the target percentage shall be the target percentage established for you for the preceding year (but adjusted, if necessary, for your position for the year in which the Covered Termination occurs). For the avoidance of doubt, the amount of the annual target cash bonus to which you are entitled under this Section 2(b) will be calculated: (1) assuming all articulated performance goals for such bonus (including, but not limited to, corporate and individual performance, if applicable), for the year of the Covered Termination was achieved at target levels; (2) as if you had provided services for the

------

<sup>1</sup> Insert 18 months for Tier I and 12 months for Tier II.

<sup>2</sup> Insert 150% for Tier I and 100% for Tier II.

------

entire year for which the bonus relates; and (3) ignoring any reduction in your Base Salary that would give rise to your right to resignation for Good Reason (such bonus to which you are entitled under this Section 2(b), the "***Annual Target Cash Bonus Severance Payment***"). The Annual Target Cash Bonus Severance Payment shall be paid in a lump sum cash payment no later than the second regular payroll date following the later of (i) the effective date of the Release or (ii) the Closing, but in any event not later than March 15 of the year following the year in which your Separation from Service occurs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(c)** **Payment of Continued Group Health Plan Benefits.** If you timely elect continued group health plan continuation coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985 ("***COBRA***") following your Covered Termination date, the Company Group shall pay directly to the carrier the full amount of your COBRA premiums on your behalf for your continued coverage under the Company Group's group health plans, including coverage for your eligible dependents, until the earliest of (i) the end of the Severance Period following your Covered Termination date, (ii) the expiration of your eligibility for the continuation coverage under COBRA, or (iii) the date when you become eligible for substantially equivalent health insurance coverage in connection with new employment (such period from your termination date through the earliest of (i) through (iii), the "***COBRA Payment Period***"). Upon the conclusion of such period of insurance premium payments made by the Company Group, you will be responsible for the entire payment of premiums (or payment for the cost of coverage) required under COBRA for the duration of your eligible COBRA coverage period, if any. For purposes of this Section, (1) references to COBRA shall be deemed to refer also to analogous provisions of state law and (2) any applicable insurance premiums that are paid by the Company Group shall not include any amounts payable by you under an Internal Revenue Code Section 125 health care reimbursement plan, which amounts, if any, are your sole responsibility. You agree to promptly notify the Company Group as soon as you become eligible for health insurance coverage in connection with new employment or self-employment.

Notwithstanding the foregoing, if at any time the Company Group determines, in its sole discretion, that it cannot provide the COBRA premium benefits without potentially incurring financial costs or penalties under applicable law (including, without limitation, Section 2716 of the Public Health Service Act), then in lieu of paying COBRA premiums directly to the carrier on your behalf, the Company Group will instead pay you on the last day of each remaining month of the COBRA Payment Period a fully taxable cash payment equal to the value of your monthly COBRA premium for the first month of COBRA coverage, subject to applicable tax withholding (such amount, the "***Special Severance Payment***"), such Special Severance Payment to be made without regard to your election of COBRA coverage or payment of COBRA premiums and without regard to your continued eligibility for COBRA coverage during the COBRA Payment Period. Such Special Severance Payment shall end upon expiration of the COBRA Payment Period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(d)** **Equity Acceleration.** The vesting and exercisability of each outstanding unvested stock option and other stock award, as applicable, that you hold covering Shares as of your Covered Termination date (each, an "***Equity Award***") that is subject to time-vesting shall be accelerated in full and any reacquisition or repurchase rights held by the Company Group in respect of Shares issued pursuant to any time-vesting Equity Award granted to you shall lapse in full. To the extent your Covered Termination occurs prior to the Change in Control, the acceleration set

------

forth in this Section 2(d) shall be contingent and effective upon the Change in Control and your Equity Awards will remain outstanding following your Covered Termination to give effect to such acceleration as necessary. For the avoidance of doubt, any Equity Awards subject to performance-vesting shall vest and become exercisable according to their individual award agreements.

**Section 3.** **Non-Change in Control Severance Benefits.**

If you are terminated in a Covered Termination that occurs at a time that is not during the Change in Control Period, you will receive:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(a)**the base salary cash payment described in Section 2(a) above, but the Severance Period for purposes of calculating such benefits shall be [<u>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</u>]<sup>3</sup> months;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(b)**[the Annual Target Cash Bonus Severance Payment described in Section 2(b) above, except that it will be equal to 100% of the annual target cash bonus established for you, if any, pursuant to the annual performance bonus or annual variable compensation plan established by the Committee (or any authorized committee or designee thereof) for the year in which your Covered Termination occurs;]<sup>4</sup>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(c)**the COBRA benefits described in Section 2(c) above, but the Severance Period for purposes of calculating such benefits shall be [<u>&nbsp;&nbsp;&nbsp;&nbsp;</u> ]<sup>5</sup> months; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(d)**acceleration of the vesting and exercisability (as applicable) of any then-outstanding time-vesting Equity Awards to the extent such awards were scheduled to vest during the [<u>&nbsp;&nbsp;&nbsp;&nbsp;</u> ]<sup>6</sup>-month period following your Covered Termination date based solely on your continued employment with the Company Group, had you remained employed by the Company Group through such date, such that such portion of your then-outstanding time-vesting Equity Awards will be deemed immediately vested and exercisable (as applicable) as of the date immediately preceding your Covered Termination date.

You shall not be eligible to receive any other benefits under the Plan except as described in this Section 3.

For the avoidance of doubt, in no event shall you be entitled to benefits under both Section 2 above and this Section 3. If you are eligible for severance benefits under both Section 2 and this Section 3, you shall receive the benefits set forth in Section 2 and such benefits shall be reduced by any benefits previously provided to you under this Section 3.

| **Section 4.** | **Change in Control Acceleration Upon Acquiror's Failure to Assume, Continue or Substitute.** |

If (i) in connection with a Change in Control, any outstanding unvested Equity Award that you hold will not be assumed or continued by the successor or acquiror entity (or its

parent company) in such Change in Control or substituted for a similar award of the successor or acquiror entity (or its parent company) (a "***Terminating Award***") and (ii) your continued employment with the Company Group has not terminated as of immediately prior to the effective time of such Change in Control, then you will become vested with respect to any then-unvested portion of such Terminating Award, effective immediately prior to, but subject to the consummation of such Change in Control. With respect to any such outstanding Terminating Award that is subject to performance-vesting, unless otherwise provided in the individual grant notice and award agreement evidencing such award, such performance-vesting award will accelerate vesting at 100% of the target level. For the avoidance of doubt, the benefits under this Section 4 are contingent on a Change in Control and do not require your Covered Termination or other termination of service. In addition, you may be eligible for benefits under this Section 4 in addition to benefits under Section 2 or Section 3 above, and in such case, you shall receive benefits under both sections, without duplication.

**Section 5.** **Acknowledgements; Interaction with Prior Benefits.**

As a condition to participation in the Plan, you hereby acknowledge each of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(a)**The benefits that may be provided to you under this Participation Agreement are subject to certain reductions and termination under the Plan, including without limitation under Section 2 and Section 3 of the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(b)**Your eligibility for and receipt of any severance benefits to which you may become entitled as described in Section 2 or Section 3 above is expressly contingent upon your execution of and compliance with the terms and conditions of the Plan, the Release and the Confidentiality Agreement. Severance benefits under this Participation Agreement shall immediately cease in the event of your violation of the provisions of Confidentiality Agreement or any other written agreement with the Company Group, or as otherwise may be set forth in the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(c)**As further described in Section 2(c) of the Plan, this Participation Agreement is entered into without reliance on any promise or representation, written or oral, other than those expressly contained herein, and it supersedes and replaces any change in control or severance benefits previously provided to you, including but not limited to the benefits under the [executive employment agreement/offer letter agreement/employment contract] dated [DATE] between you and the Company Group (the "***Employment Agreement***"), provided that your Equity Awards shall remain subject to the terms of the Equity Plan or other applicable equity plan under which such awards were granted (including the award documentation governing such awards) that may apply upon a Change in Control and/or termination of your service. You agree and acknowledge that there are no circumstances as of the date of this Participation Agreement that constitute, and nothing contemplated in this Participation Agreement shall be deemed for any purpose to be or to create, a termination without Cause or a Good Reason resignation right, including for purposes of the Employment Agreement, or any other severance or change in control plan, agreement or policy maintained by the Company Group. You further hereby expressly waive any claim or right you may have as of the date of this Participation Agreement (if any) to assert that this Participation Agreement, or any other condition or occurrence, forms the basis for a

------

without Cause termination or Good Reason resignation for any purpose, including for purposes of the Employment Agreement, or any other severance or change in control plan, agreement or policy maintained by the Company Group.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(d)**If any particular provision of the Plan or this Participation Agreement is found to be invalid or otherwise unenforceable, such provision will not affect the other provisions of the Plan or this Participation Agreement, but the Plan and this Participation Agreement will be construed in all respects as if such invalid provision were omitted.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(e)**If any provision of the Plan or this Participation Agreement does not comply with applicable law, such provision shall be construed in such a manner as to comply with applicable law.

To accept the terms of this Participation Agreement and participate in the Plan, please sign and date this Participation Agreement in the space provided below and return it to <u>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</u> no later than <u>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</u> , <u>&nbsp;&nbsp;&nbsp;&nbsp;</u> .

**CERTIFICATION PURSUANT TO**
