Amendment Description	Structure Therapeutics Inc., or “we,” “us,” and “our,” is filing this Amendment No. 2 on Form 10-Q/A (the “Second Amended Filing”) to amend our Quarterly Report on Form 10-Q for the quarter ended June 30, 2023 (the “Quarterly Report”), which was originally filed with the Securities and Exchange Commission (“SEC”) on August 10, 2023 (the “Original Filing”) and subsequently amended on November 16, 2023 (the ““First Amended Filing”, and together with the Original Filing, the “Prior Filings”).As previously disclosed, the interim unaudited condensed consolidated financial statements as of and for the three and six months ended June 30, 2022 (the “2022 Interim Financial Statements”) were not previously reviewed by an independent registered public accounting firm in accordance with Public Company Accounting Oversight Board Auditing Standard 4105, Reviews of Interim Financial Information (“PCAOB AS 4105”). As a result, the Prior Filings were substantially deficient and not considered timely filed or current.This Second Amended Filing is being filed solely for the purpose of (i) removing the references to “Not Reviewed” in the headings in the columns and related notes thereto in the First Amended Filing; and (ii) disclosing that the Quarterly Report is no longer substantially deficient. This Second Amended Filing speaks as of the filing date of the Original Filing and does not reflect events occurring after the filing date of the Original Filing or modify or update any of the other information contained in the Original Filing in any way. Accordingly, this Second Amended Filing should be read in conjunction with the Prior Filings.

Organization and Nature of the Business
Organization and Nature of the Business	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 needs. 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 articles of association. 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 $158.2 million as of June 30, 2023. Historically, the Company has financed its operations primarily through the private placement of equity securities. On February 7, 2023, the Company completed its IPO for net proceeds of approximately $166.7 million, after deducting underwriting discounts and estimated offering costs. As of June 30, 2023, the Company had cash, cash equivalents and short-term investments of $224.6 million. The Company’s condensed consolidated financial statements have been prepared on the basis of the Company continuing as a going concern for the next 12 months. 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. Impact of Geopolitical and Macroeconomic Factors There may be significant uncertainty resulting from the impact of other geopolitical and macroeconomic factors, including global pandemics, inflation, supply chain issues, rising interest rates, future bank failures, increased geopolitical tensions between the U.S. and China and the impact of the Russia/Ukraine conflict.

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 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, 2022 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 June 30, 2023 and for the three and six months ended June 30, 2023 and 2022, have been prepared by the Company, pursuant to the rules and regulations of the Securities and Exchange Commission (“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, 2022 and notes thereto, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 filed with the SEC on March 30, 2023. 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 position as of June 30, 2023 and condensed consolidated results of operations for the three and six months ended June 30, 2023 and 2022 and condensed consolidated cash flows for the six months ended June 30, 2023 and 2022 have been made. The results of operations for the three and six months ended June 30, 2023 are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2023. 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, ordinary share valuation and related share-based compensation and certain other accrued liabilities. Actual results could differ from those estimates. 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 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 early-stage 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 trials and regulatory approval prior to commercialization. These efforts require significant amounts of additional resources, adequate personnel, infrastructure and extensive compliance and reporting. The Company’s product candidates are still in development and, to date, none of the Company’s product candidates have been approved for sale and, therefore, the Company has not generated any revenue from any of its products. There can be no assurance that the Company’s research and development will be successfully completed, that adequate protection for the Company’s intellectual property will be obtained or maintained, that any products developed will obtain necessary government regulatory approval or that any approved products will be commercially viable. Even if the Company’s product development efforts are successful, it is uncertain when, if ever, the Company will generate any revenue from any of its products. The Company operates in an environment of rapid change in technology and substantial competition from other pharmaceutical and biotechnology companies. The Company relies and expects to continue to rely on a small number of vendors to manufacture supplies and materials for its use in the clinical trial programs. These programs could be adversely affected by a significant interruption in these manufacturing services. Credit Losses For short-term investments in an unrealized loss position, the Company periodically assesses its portfolio for impairment. The assessment first considers the intent or requirement to sell the available-for-sale debt securities. If either of these criteria are met, the amortized cost basis will be written down to fair value through earnings. If not met, the Company evaluates whether the decline resulted from credit losses or other factors by considering the extent to which fair value is less than amortized cost, any changes to the rating of the short-term investments by a rating agency, and any adverse conditions specifically related to the short-term investments, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the short-term investments is compared to the amortized cost basis of the short-term investments. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded, with a corresponding adjustment to interest and other income (expense), net, limited by the amount that the fair value is less than the amortized cost basis. The Company has elected to exclude accrued interest from both the fair value and the amortized cost basis of the available-for-sale debt securities for the purposes of identifying and measuring an impairment. The Company writes off accrued interest as a reduction of interest income when an issuer has defaulted on interest payments due on a security. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive loss. 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. Fair Value Measurements). Deferred Offering Costs The Company capitalizes, within other non-current assets, certain legal, accounting and other third-party fees that are directly related to the Company’s in-process equity financings, including its IPO, until such financings are consummated. After consummation of the equity financing, these costs are recorded as a reduction of the proceeds received as a result of the offering. Should a planned equity financing be abandoned, terminated or significantly delayed, the deferred offering costs will be immediately written off to general and administrative expenses. Upon closing the IPO, all deferred offering costs were charged against the proceeds from the IPO and recorded in shareholders equity (deficit) as a reduction of additional paid-in capital. As of June 30, 2023, there were no deferred offering costs recorded on the condensed consolidated balance sheets. 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. Net loss attributable to ordinary shareholders is computed as net loss less accretion of redeemable convertible preferred shares. Diluted net loss per 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 redeemable convertible preferred shares, ordinary share warrants, unvested restricted ordinary shares subject to repurchase and share options are considered to be potentially dilutive securities. Basic and diluted net loss per share attributable to ordinary shareholders is presented in conformity with the two-class method required for participating securities as the redeemable convertible preferred shares are considered a participating security because they participate in dividends with ordinary shares. The holders of redeemable convertible preferred shares do not have a contractual obligation to share in the Company’s losses. As such, the net loss was attributed entirely to ordinary shareholders, including non-voting ordinary shares. 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.

Fair Value Measurements
Fair Value Measurements	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. 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): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ JUNE 30, ​ DECEMBER 31, ​ ​ 2023 ​ 2022 ​ LEVEL 1 LEVEL 2 LEVEL 3 TOTAL LEVEL 1 LEVEL 2 LEVEL 3 TOTAL Money market funds ​ $ 25,592 ​ $ — ​ $    — ​ $ 25,592 ​ $ 18,994 ​ $ — ​ $    — ​ $ 18,994 ​ Commercial paper ​ ​ — ​ ​ 9,975 ​ ​ — ​ ​ 9,975 ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ Cash equivalents ​ 25,592 ​ 9,975 ​ — ​ 35,567 ​ 18,994 ​ — ​ — ​ 18,994 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. government bonds ​ ​ 43,269 ​ ​ — ​ ​ — ​ ​ 43,269 ​ ​ 11,763 ​ ​ — ​ ​ — ​ ​ 11,763 ​ U.S. government agency bonds ​ ​ — ​ ​ 33,846 ​ ​ — ​ ​ 33,846 ​ ​ — ​ ​ 1,794 ​ ​ — ​ ​ 1,794 ​ Corporate debt securities ​ — ​ 106,881 ​ — ​ 106,881 ​ — ​ 51,193 ​ — ​ 51,193 ​ Short-term investments ​ 43,269 ​ 140,727 ​ — ​ 183,996 ​ 11,763 ​ 52,987 ​ — ​ 64,750 ​ Total fair value of financial assets ​ $ 68,861 ​ $ 150,702 ​ $ — ​ $ 219,563 ​ $ 30,757 ​ $ 52,987 ​ $ — ​ $ 83,744 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ JUNE 30, ​ DECEMBER 31, ​ ​ 2023 2022 ​ ​ AMORTIZED GROSS UNREALIZED FAIR ​ AMORTIZED GROSS UNREALIZED FAIR ​ COST ​ LOSSES ​ GAINS VALUE COST ​ LOSSES ​ GAINS VALUE Money market funds ​ $ 25,592 ​ $ — ​ $ — ​ $ 25,592 ​ $ 18,994 ​ $ — ​ $    — ​ $ 18,994 ​ Commercial paper ​ ​ 9,970 ​ ​ — ​ ​ 5 ​ ​ 9,975 ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ Cash equivalents ​ 35,562 ​ — ​ 5 ​ 35,567 ​ 18,994 ​ — ​ — ​ 18,994 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. government bonds ​ ​ 43,433 ​ ​ (164) ​ ​ — ​ ​ 43,269 ​ ​ 11,820 ​ ​ (57) ​ ​ — ​ ​ 11,763 ​ U.S. government agency bonds ​ ​ 33,914 ​ ​ (77) ​ ​ 9 ​ ​ 33,846 ​ ​ 1,801 ​ ​ (7) ​ ​ — ​ ​ 1,794 ​ Corporate debt securities ​ 107,044 ​ (166) ​ 3 ​ 106,881 ​ 51,239 ​ (49) ​ 3 ​ 51,193 ​ Short-term investments ​ 184,391 ​ (407) ​ 12 ​ 183,996 ​ 64,860 ​ (113) ​ 3 ​ 64,750 ​ Total fair value of financial assets ​ $ 219,953 ​ $ (407) ​ $ 17 ​ $ 219,563 ​ $ 83,854 ​ $ (113) ​ $ 3 ​ $ 83,744 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of June 30, 2023 and December 31, 2022, the Company did not have any liabilities measured at fair value on a recurring basis.

Some of the provisions will limit losses to those arising from third-party actions. In some cases, the indemnification will continue after the termination of the agreement. The maximum potential number of future payments the Company could be required to make under these provisions is not determinable. The Company has never incurred material costs to defend lawsuits or settle claims related to these indemnification provisions. The Company has also entered into indemnification agreements with its directors and officers that require the Company, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors or officers to the fullest extent permitted by the applicable law and the amended and restated memorandum and articles of association of the Company. The Company currently has directors’ and officers’ liability insurance.

Shareholders’ Equity As of June 30, 2023, the Company’s Memorandum and Articles of Association, as amended, authorizes the Company to issue 500,000,000 ordinary shares and 100,000,000 undesignated shares, of which 7,410,518 shares have been designated as non-voting ordinary shares and 92,589,482 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 Articles of Association. In May 2023, the Company’s board of directors designated 7,410,518 non-voting ordinary shares in accordance with the Articles of Association. The non-voting ordinary shares rank on parity with the ordinary shares as to distributions of assets upon liquidation, dissolution or winding up of the Company, whether voluntary or involuntary. The non-voting ordinary shares are entitled on an equal basis to any dividends declared on the ordinary shares on an as-converted to ordinary share basis. Each non-voting ordinary shareholder has the right to convert each non-voting ordinary share into one ordinary share, subject to appropriate adjustment in the event of any dividend, split, reverse split, combination or other similar recapitalization with respect to the ordinary shares, at such holder’s election by providing written notice to the Company, provided that such non-voting ordinary shares may only be converted into ordinary shares during such time or times as immediately prior to or as a result of such conversion would not result in the holder thereof beneficially owning, when aggregated with affiliates with whom such holder is required to aggregate beneficial ownership for purposes of Section 13(d) of the Exchange Act, in excess of the 9.99% of the ordinary shares (The “Beneficial Ownership Limitation”). Any non-voting ordinary shareholder may increase the Beneficial Ownership Limitation with respect to such holder, not to exceed 19.99% of the ordinary shares, upon 61 days’ prior written notice to the Company and may decrease the Beneficial Ownership Limitation at any time upon providing written notice of such election to the Company; provided, however, that no holder may make such an election to change the percentage with respect to such holder unless all holders managed by the same investment advisor as such electing holder make the same election. In May 2023, the Company entered into an Exchange Agreement with Biotechnology Value Fund, L.P., Biotechnology Value Fund II, L.P., and Biotechnology Value Trading Fund OS, L.P. (each an “Investor” and together, the “Investors”), who in the aggregate hold more than 5% of the Company’s issued share capital, pursuant to which the Investors delivered to the Company, a total of 7,410,518 ordinary shares of the Company, in exchange for the Company’s delivery of 7,410,518 newly designated non-voting ordinary shares, par value $0.0001 per share. The exchange did not result in any change in the aggregate number of outstanding shares of the Company as the exchange was implemented on a one-for-one basis. Ordinary shareholders, including non-voting ordinary shareholders, are entitled to dividends if and when declared by the Company’s board of directors subject to the prior rights of any preferred shareholders. As of June 30, 2023 and December 31, 2022, no dividends on ordinary shares had been declared by the board of directors.

China Employees’ Options The Company has granted share options to employees based in China. The exercise of share options granted to such employees was conditioned on a liquidity event, such as an IPO or change in control, which was not considered probable until consummated. The liquidity event condition was satisfied upon the closing of the IPO, and the Company recognized cumulative share-based compensation expense for share options granted to employees based in China. For the three and six months ended June 30, 2023, the Company recognized $0.2 million and $1.7 million in share-based compensation expense related to share options granted to employees based in China, respectively. 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 will 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 achievement of performance milestones was not probable as of June 30, 2023. As such, no share-based compensation expense has been recognized for performance share options during the six months ended June 30, 2023. Ordinary Share Warrants In connection with entering into a Loan and Security Agreement (the “SVB Agreement”) with Silicon Valley Bank (“SVB”), the Company issued SVB a warrant to purchase shares of its ordinary shares at an exercise price of $0.48 per share (“SVB Warrant”). The SVB Warrant was immediately exercisable for 112,279 ordinary shares of the Company and could have been exercisable for an additional number of ordinary shares equal to 44,567 ordinary shares upon draw of Tranche A under the SVB Agreement and 22,283 ordinary shares upon draw of Tranche B under the SVB Agreement. The warrant for Tranche A shares and Tranche B shares expired on July 31, 2021 and July 31, 2022, respectively, as the Company elected to allow the Tranche A and Tranche B financings to expire unused on July 31, 2021 and July 31, 2022, respectively. In February 2023, SVB fully exercised the SVB Warrant for 106,060 ordinary shares through a cashless exercise.

Related Party Transactions	9. Related Party Transactions Ramy Farid, the President and Chief Executive Officer of Schrödinger, Inc. (“Schrödinger”) is a member of the Company’s board of directors. During the three and six months ended June 30, 2023 and 2022, the Company had existing collaboration agreements to use the results provided by Schrödinger’s software platform for its research purposes. During the three months ended June 30, 2023 and 2022, the Company paid $0 and less than $0.1 million to Schrödinger, respectively. During the six months ended June 30, 2023 and 2022, the Company paid $0 and $0.2 million to Schrödinger, respectively, and had no payable balance to Schrödinger as of June 30, 2023 and December 31, 2022. Lhotse Collaboration Agreement with Schrödinger In In October 2020, Lhotse Bio, Inc., the Company’s wholly-owned subsidiary, entered into a Collaboration Agreement (the “Lhotse-Schrödinger Agreement”) with Schrödinger to discover and develop novel, orally bioavailable, small molecule inhibitors of LPA1R. Under the Lhotse-Schrödinger Agreement, Schrödinger is obligated to provide computational modeling and design support, including by using its technology platform to perform virtual screens, and Lhotse is obligated to provide day-to-day chemistry and biology support. Pursuant to the Lhotse-Schrödinger Agreement, a joint steering committee comprised of representatives from both parties oversees the research performed under the agreement. During the term of the Lhotse-Schrödinger Agreement and for a specified period thereafter while Lhotse is engaged in active development of any compound having activity against LPA1R that is discovered or developed under the Lhotse-Schrödinger Agreement, Schrödinger is obligated to work exclusively with Lhotse on the design, research, development and commercialization of compounds that inhibit LPA1R. Lhotse will solely own the research results, work product, inventions and other intellectual property generated under the Lhotse-Schrödinger Agreement that are directed to LPA1R. Under the Lhotse-Schrödinger Agreement, Lhotse is obligated to pay Schrödinger a quarterly active program payment in the low six digits for each successive three-month period during which Schrödinger continues to perform research work as agreed by the parties, and as of June 30, 2023, the Company has paid to Schrödinger an aggregate of $0.8 million. If Lhotse develops and commercializes a product containing a compound (a “Collaboration Compound”), that is discovered or developed under the Lhotse-Schrödinger Agreement (a “Collaboration Product”), Lhotse is obligated to pay Schrödinger development and regulatory milestone payments of up to an aggregate of $17.0 million, regardless of the number of Collaboration Products that reach such milestones. Lhotse will also be obligated to pay Schrödinger tiered royalties on a Collaboration Product-by-Collaboration Product basis equal to low single digit percentages on aggregate worldwide net sales of Collaboration Products, subject to specified reductions and offsets. Lhotse’s obligation to pay royalties to Schrödinger will expire on a Collaboration Product-by-Collaboration Product and country-by-country basis on the later of (i) the expiration of the last-to-expire Lhotse patent claim covering the composition of matter of the Collaboration Compound contained in such Collaboration Product in such country, (ii) the expiration of regulatory, pediatric, orphan drug, or data exclusivity with respect to such Collaboration Product in such country, and (iii) ten years after the first commercial sale of such Collaboration Product in such country (the “Royalty Term”). Unless terminated earlier, the Lhotse-Schrödinger Agreement will continue for three years, subject to extension by mutual written agreement of the parties. Either party may terminate the Lhotse-Schrödinger Agreement for the other party’s uncured material breach, subject to certain notice and cure periods, or for the other party’s bankruptcy or insolvency. Lhotse’s obligation to make milestone and royalty payments (subject to the Royalty Term) to Schrödinger continues after the expiration or termination of the Lhotse-Schrödinger Agreement. As of June 30, 2023, no milestone or royalty payments have been paid or accrued.

Summary of Significant Accounting Policies
Basis of Presentation	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 loss included in determining net loss was not material for the periods presented.
Unaudited Interim Financial Information	Unaudited Interim Financial Information The condensed consolidated balance sheet as of December 31, 2022 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 June 30, 2023 and for the three and six months ended June 30, 2023 and 2022, have been prepared by the Company, pursuant to the rules and regulations of the Securities and Exchange Commission (“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, 2022 and notes thereto, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 filed with the SEC on March 30, 2023. 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 position as of June 30, 2023 and condensed consolidated results of operations for the three and six months ended June 30, 2023 and 2022 and condensed consolidated cash flows for the six months ended June 30, 2023 and 2022 have been made. The results of operations for the three and six months ended June 30, 2023 are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2023.
Use of Estimates	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, ordinary share valuation and related share-based compensation and certain other accrued liabilities. Actual results could differ from those estimates.
Concentration of Credit Risk	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 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	Risks and Uncertainties The Company is subject to risks and uncertainties common to early-stage 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 trials and regulatory approval prior to commercialization. These efforts require significant amounts of additional resources, adequate personnel, infrastructure and extensive compliance and reporting. The Company’s product candidates are still in development and, to date, none of the Company’s product candidates have been approved for sale and, therefore, the Company has not generated any revenue from any of its products. There can be no assurance that the Company’s research and development will be successfully completed, that adequate protection for the Company’s intellectual property will be obtained or maintained, that any products developed will obtain necessary government regulatory approval or that any approved products will be commercially viable. Even if the Company’s product development efforts are successful, it is uncertain when, if ever, the Company will generate any revenue from any of its products. The Company operates in an environment of rapid change in technology and substantial competition from other pharmaceutical and biotechnology companies. The Company relies and expects to continue to rely on a small number of vendors to manufacture supplies and materials for its use in the clinical trial programs. These programs could be adversely affected by a significant interruption in these manufacturing services.
Credit Losses	Credit Losses For short-term investments in an unrealized loss position, the Company periodically assesses its portfolio for impairment. The assessment first considers the intent or requirement to sell the available-for-sale debt securities. If either of these criteria are met, the amortized cost basis will be written down to fair value through earnings. If not met, the Company evaluates whether the decline resulted from credit losses or other factors by considering the extent to which fair value is less than amortized cost, any changes to the rating of the short-term investments by a rating agency, and any adverse conditions specifically related to the short-term investments, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the short-term investments is compared to the amortized cost basis of the short-term investments. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded, with a corresponding adjustment to interest and other income (expense), net, limited by the amount that the fair value is less than the amortized cost basis. The Company has elected to exclude accrued interest from both the fair value and the amortized cost basis of the available-for-sale debt securities for the purposes of identifying and measuring an impairment. The Company writes off accrued interest as a reduction of interest income when an issuer has defaulted on interest payments due on a security. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive loss.
Fair Value of Financial Instruments	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. Fair Value Measurements).
Deferred Offering Costs	Deferred Offering Costs The Company capitalizes, within other non-current assets, certain legal, accounting and other third-party fees that are directly related to the Company’s in-process equity financings, including its IPO, until such financings are consummated. After consummation of the equity financing, these costs are recorded as a reduction of the proceeds received as a result of the offering. Should a planned equity financing be abandoned, terminated or significantly delayed, the deferred offering costs will be immediately written off to general and administrative expenses. Upon closing the IPO, all deferred offering costs were charged against the proceeds from the IPO and recorded in shareholders equity (deficit) as a reduction of additional paid-in capital. As of June 30, 2023, there were no deferred offering costs recorded on the condensed consolidated balance sheets.
Net Loss Per Share Attributable to Ordinary Shareholders	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. Net loss attributable to ordinary shareholders is computed as net loss less accretion of redeemable convertible preferred shares. Diluted net loss per 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 redeemable convertible preferred shares, ordinary share warrants, unvested restricted ordinary shares subject to repurchase and share options are considered to be potentially dilutive securities. Basic and diluted net loss per share attributable to ordinary shareholders is presented in conformity with the two-class method required for participating securities as the redeemable convertible preferred shares are considered a participating security because they participate in dividends with ordinary shares. The holders of redeemable convertible preferred shares do not have a contractual obligation to share in the Company’s losses. As such, the net loss was attributed entirely to ordinary shareholders, including non-voting ordinary shares. 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.
