Accounting Policies [Abstract] |
Basis of Presentation | Basis of Presentation The accompanying consolidated financial statements include the accounts of the Company and its controlled subsidiaries have been prepared in accordance with U.S. GAAP. Intercompany accounts and transactions, if applicable, have been eliminated in consolidation.
Use of Estimates | Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. On an ongoing basis, management evaluates its estimates, including those related to revenue recognition, allowance of doubtful accounts, long-term receivable, CVR derivative liability, warrant liability, allowance for credit losses, reserves for excess or obsolete inventory, operating lease right-of-use assets and liabilities, recognition of research and development expenses to the appropriate financial reporting period based on the progress of the research and development projects, income taxes, stock-based compensation and useful lives of property and equipment and intangibles with definite lives. The Company bases its estimates on various assumptions that the Company believes to be reasonable under the circumstances. Actual results could differ from those estimates.
Noncontrolling Interest | Noncontrolling Interest The Company reports noncontrolling interest (“NCI”) in a subsidiary as a separate component of equity in the consolidated balance sheets. Additionally, the Company reports the portion of net income (loss) and comprehensive income (loss) attributed to the Company and NCI separately in the consolidated statements of operations and comprehensive income (loss).
Segments | Segments Operating segments are defined as components of an entity for which separate financial information is available and that is regularly reviewed by the Chief Operating Decision Maker (“CODM”) in deciding how to allocate resources to an individual segment and in assessing performance. The Company’s CODM, as a group, includes Gyre’s Chief of Executive Officer (“CEO”), BC’s General Manager, and the Chairman of Gyre’s Board of Directors (“Gyre’s Board”). The Company has determined that it operates in two distinct operating segments and has two reportable segments.
Risks and Uncertainities | Risks and Uncertainties The Company is subject to a number of risks associated with companies at a similar stage, including dependence on key individuals, competition from larger and established companies, uncertainty of clinical results, ability to obtain adequate financing to support growth, the ability to attract and retain additional qualified personnel to manage the anticipated growth of the Company, and general economic conditions.
Concentration of Credit Risk | Concentration o f Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash, accounts and note receivable, and long-term certificates of deposits. As of December 31, 2023 and 2022, the Company had cash of $33.5 million and $25.2 million, respectively, and long-term certificates of deposit of $23.4 million and $7.4 million, respectively. The Company is exposed to United States credit risk in the event of default by the United States institutions holding cash to the extent beyond the amount insured by the United States federal depository insurance corporation. In May 2015, a new Deposit Insurance System (“DIS”) managed by the People’s Bank of China was implemented by the Chinese government. Deposits in the licensed banks in mainland China are protected by DIS, up to a limit of Chinese Renminbi (“RMB”) 500,000. The Company maintains cash and deposits in excess of the amount protected by DIS and in the event of bankruptcy of one of these financial institutions, the Company may be unable to claim its deposits back in full. Management believes that these financial institutions are of high credit quality and continually monitors the creditworthiness of these financial institutions. Ac counts receivable are typically unsecured and are derived from product sales. The Company manages credit risk related to the accounts receivable through ongoing monitoring of outstanding balances and limiting the amount of credit extended based upon payment history and creditworthiness. Historically, the Company has collected receivables from customers within the credit terms with no significant credit losses incurred.
Concentration of Customer Risk | Concentration of Customer Risk For the years ended December 31, 2023 and 2022, one customer, Sinopharm Group Co., Ltd., accounted for approximately 50.5% and 45.1%, of accounts receivable, respectively. For the year ended December 31, 2023, three customers known as Sinopharm Group Co., Ltd., China Resources Pharmaceutical Group Ltd, and Shanghai Pharmaceuticals Holding Co., Ltd accounted for approximately 50.1%, 13.7%, and 11.2% of total revenue respectively. For the year ended December 31, 2022, three customers known as Sinopharm Group Co., Ltd., Shanghai Pharmaceuticals Holding Co., Ltd, and China Resources Pharmaceutical Group Ltd accounted for approximately 47.7%, 11.6%, and 10.8% of total revenue respectively. All customers are located in the PRC.
Cash and Cash Equivalents | Cash and Cash Equivalents The Company invests portion of its excess cash in bank deposits, consisting primarily of money market mutual funds. The Company considers all highly liquid investments with original maturities of three months or less from the date of purchase to be cash equivalents.
Fair Value Measurements | Fair Value Measurements The Company applies fair value accounting for all financial assets and liabilities and non-financial assets and liabilities that are recognized or disclosed at fair value in the consolidated financial statements on a recurring basis. Fair value is defined as the exchange price that would be received for an asset or an exit price that would be paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy requires that an entity maximize the use of observable inputs when estimating fair value. The fair value hierarchy includes the following three-level classification which is based on the market observability of the inputs used for estimating the fair value of the assets or liabilities being measured: Level 1 – Quoted prices in active markets for identical assets or liabilities. Level 2 – Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 – Inputs that are generally unobservable and typically reflect management’s estimate of assumptions that market participants would use in pricing the asset or liability. For assets and liabilities that are recognized in the financial statements at fair value on a recurring basis, the Company determines whether transfers have occurred between levels in the hierarchy by reassessing categorization (based on the lowest level input that is significant to the fair value measurement as a whole) at the end of each reporting period.
Derivative Financial Instruments | Derivative Financial Instruments The Company evaluates its contracts to determine if those contracts qualify as derivatives under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 815, Derivatives and Hedging. For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value and is then re-valued at each reporting date. Any changes in fair value are recorded as non-operating, non-cash other income or expense for each reporting period. Derivative instrument liabilities are classified in the balance sheet as current or non-current based on whether or not net-cash settlement of the derivative instrument is probable within the next 12 months from the balance sheet date. The Company determined that certain contingent payments under the CVR Agreement qualified as derivatives under ASC 815, and as such, were recorded as a liability. Refer to Note 3 — Fair Value Measurements and Financial Instruments and Note 13 — Commitments and Contingencies for additional information regarding the CVR derivative liability.
Preferred Stock Warrants | Preferred Stock Warrants Warrants to purchase shares of the Convertible Preferred Stock (“Preferred Stock Warrants”) are freestanding financial instruments classified as warrant liability on the Company’s consolidated balance sheets since the underlying securities are contingently redeemable upon the occurrence of events which are outside of the Company’s control. The Preferred Stock Warrants are recorded at fair value upon issuance and are subject to remeasurement at the end of each reporting period. Any change in the fair value of the Preferred Stock Warrants is recorded as changes in fair value of warrant liability in other income (expense), net on the consolidated statement of operations and comprehensive income (loss). The Company adjusts the liability for changes in fair value of the Preferred Stock Warrants until the warrants are exercised or expired.
Convertible Preferred Stock | Convertible Preferred Stock The Company records shares of non-voting Convertible Preferred Stock at its relative fair value on the date of issuance. The Company applied the guidance in ASC 480-10-S99-3A, SEC Staff Announcement: Classification and Measurement of Redeemable Securities, to account for the Convertible Preferred Stock. The Convertible Preferred Stock could become redeemable upon the occurrence of an event that is not solely within the control of the issuer and therefore, is classified within mezzanine equity in the accompanying consolidated balance sheets.
Long-term Certificates of Deposit | Long-term Certificates of Deposit The long-term certificates of deposit will mature between February 2025 and July 2026. Certificates of deposit are accounted for at amortized cost with no adjustments for changes in fair value. Premiums and discounts, if any, are amortized or accreted over the lives of the related fixed maturities as an adjustment to the yield using the effective interest method. The Company recorded no allowance for credit losses associated with the certificates of deposit as of December 31, 2023 and 2022.
Long-Term Receivable | Long-Term Receivable Catalyst sold its legacy rare bleeding disorder program to GC Biopharma Corp. (“GCBP”) in February 2023. The Company determined that the hold-back from the GCBP asset sale qualified as a long-term receivable. The receivable is considered a loan held for investment since the Company has the intent and ability to hold to maturity. The Company has elected to account for the receivable under the fair value option method of accounting and any changes in fair value are recorded in interest and other income, net on the consolidated statement of operations and comprehensive income (loss). Refer to Note 3 — Fair Value Measurements and Financial Instruments for additional information regarding the long-term receivable.
Accounts and Note Receivables, Net | Accounts and Note Receivables, Net The Company recognizes a receivable when it has an unconditional right to payment, which represents the amount the Company expects to collect in a transaction. The Company’s trading terms with its customers are mainly on credit, and the credit period is usually within three months. Accounts and note receivables are recorded at net realizable value. The allowance for credit losses is determined by management’s best estimate of expected credit losses of the receivables based on historical data, current information, and future economic forecasts. Receivables are grouped into asset pools based on delinquency status and customer type, with fixed reserve percentages set for each pool. The reserve percentages are determined by considering factors such as historical experience with customers, regulatory and legal environments, and other relevant current and future macroeconomic factors. Accounts and note receivables, net, consisted of the following at the dates indicated (in thousands):
|  | December 31, |
|  | 2023 |  | 2022 |
Accounts receivable |  | $ | 15,204 |  |  | $ | 15,738 |
Note receivable |  |  | 389 |  |  |  | 1,522 |
Allowance for credit losses |  |  | (41 | ) |  |  | (124 | )
Accounts and note receivables, net |  | $ | 15,552 |  |  | $ | 17,136 |
Changes in the allowance for credit losses as of December 31, 2023 and 2022 consisted of the following (in thousands):
|  | 2023 |  | 2022 |
Balance, beginning of year |  | $ | (124 | ) |  | $ | (70 | )
Provision for allowance for credit losses |  |  | — |  |  |  | (88 | )
Recoveries collected and write-off |  |  | 82 |  |  |  | 26 |
Foreign currency translation adjustments |  |  | 1 |  |  |  | 8 |
Balance, end of year |  | $ | (41 | ) |  | $ | (124 | )
Inventories, Net | Inventories, Net Inventories, consisting of raw materials, work in progress, and finished goods, are valued at the lower of cost or net realizable value with cost being determined on the first-in, first-out method. The Company will record a write-down to its net realizable value in cost of sales in the periods that the decline in value is first identified. The average cost of work in progress and finished goods consists primarily of material, labor and manufacturing overhead expenses (including fixed production-overhead costs) and includes the services and products of third-party suppliers. Net realizable value is based on estimated selling prices less any estimated costs to be incurred to completion and disposal. The Company also regularly monitors inventory quantities on hand and in transit, and reserves for excess and obsolete inventories using estimates based on historical experience, historical and projected sales trends, specific categories of inventory, and expiration and age of on-hand inventory. Inventories presented in the consolidated balance sheets are net of reserves for excess and obsolete inventory. If actual conditions or product demands are less favorable than assumptions, additional inventory reserves may be required.
Property and Equipment | Property and Equipment, Net Property and equipment, except for construction-in-progress, are stated at cost less accumulated depreciation and any impairment losses. The cost of an item of property and equipment comprises its purchase price and any directly attributable costs of bringing the asset to its working condition and location for its intended use. Expenditure incurred after items of property and equipment that have been put into operation, such as repairs and maintenance, is normally charged to profit or loss in the period in which it is incurred. In situations where the recognition criteria are satisfied, the expenditure for a major inspection is capitalized in the carrying amount of the asset as a replacement. Where significant parts of property and equipment are required to be replaced at intervals, the Company recognizes such parts as individual assets with specific useful lives and depreciates them accordingly. Depreciation is calculated on a straight-line basis over the estimated useful lives of the assets, as follows:
Buildings | 20 to 30 years
Leasehold improvement | Shorter of the estimated useful life or the term of the lease
Machinery and electronic devices | 3 to 10 years
Furniture and fixtures | 3 to 5 years
Motor vehicles | 3 to 5 years
Where parts of an item of property and equipment have different useful lives, the cost of that item is allocated on a reasonable basis among the parts and each part is depreciated separately. An item of property and equipment including any significant part initially recognized is derecognized upon disposal or when no future economic benefits are expected from its use or disposal. The difference between the net sales proceeds and the carrying amount of the asset is recorded as gain or loss in profit or loss in the reporting period the relevant asset is derecognized. Construction in progress represents a building under construction or machinery not yet put into operation, which is stated at cost less any impairment losses, if applicable, and is not depreciated. Cost comprises the direct costs of construction and machinery, and capitalized borrowing costs on related funds borrowed during the period of construction. Construction in progress is reclassified to the appropriate category of property and equipment when completed and ready for use. Property and equipment is reviewed for impairment when events or circumstances exist which suggest that the carrying amount of the asset group may not be recoverable.
Intangible Assets, Net | Intangible Assets, Net Intangible assets acquired separately are measured upon initial recognition at cost. The useful lives of intangible assets are assessed to be either finite or indefinite. Intangible assets with finite lives, consisting primarily of patents, technological know-how and computer software, are subsequently amortized over the useful economic life and assessed for impairment whenever there is an indication that the intangible asset may be impaired. Patents and Technological Know-How Patents and technological know-how that have finite useful lives are stated at cost less any impairment losses and are amortized on a basis that best reflects how their economic benefits are utilized or on the straight-line basis, if not materially different from actual utilization, over their estimated useful life of 10 to 20 years. Computer Software Purchased computer software is stated at cost less any impairment losses and is amortized on the straight-line basis over its estimated useful life of two to three years.
Leases | Leases The Company assesses at contract inception whether a contract is, or contains, a lease based on the unique facts and circumstances present. A contract is, or contains, a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. Operating lease right-of-use (“ROU”) assets represent the Company’s right to use an underlying asset during the lease term, and operating lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating leases are included in ROU assets, current operating lease liabilities, and long-term operating lease liabilities on the accompanying consolidated balance sheets. Operating lease liabilities are recognized based on the present value of the future minimum lease payments over the expected lease term at commencement date or the lease modification date, if applicable. The interest rate implicit in lease contracts is typically not readily determinable. As such, the Company utilizes its incremental borrowing rate, which is the rate incurred to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. Certain adjustments to the ROU assets may be required for items such as initial direct costs paid or incentives received. The Company determines the expected lease term as the noncancelable period of the lease and may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Leases with a term of 12 months or less are not recognized on the consolidated balance sheets. The Company recognizes lease expense for these short-term leases on a straight-line basis over the lease term. The Company’s leases do not contain any residual value guarantees. The Company has elected to combine lease and non-lease components as a single component. The lease expense for minimum lease payments is recognized over the expected term on a straight-line basis. Variable lease payments, which are primarily comprised of property maintenance, taxes, and other payments based on usage, are recognized when the expense is incurred.
Land Use Rights, Net | Land Use Rights, Net All land in mainland China is subject to government or collective ownership, and land use rights can be purchased for a specified period of time. The purchase price of land use rights represents the operating lease prepayments under ASC Topic 842, Leases and is recorded as land use rights, net asset on the consolidated balance sheets, which is amortized over the remaining lease term.
Impairment of Long-Lived Assets | Impairment of Long-Lived Assets Long-lived assets, including property and equipment, finite-lived intangible assets, ROU assets and land use rights, are reviewed for possible impairment whenever events or circumstances indicate that the carrying amount of such assets may not be recoverable. The evaluation is performed at the asset group level, i.e., the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. Recoverability of these assets is measured by a comparison of the carrying amounts of an asset group to the future undiscounted cash flows the assets are expected to generate from the use and eventual disposition. If such a review indicates the carrying amount of the asset group is not recoverable, an impairment loss shall be measured as the amount by which the carrying amount of an asset group exceeds its fair valu e. Any impairment loss is allocated to the long-lived assets of the group on a pro rata basis using the relative carrying amounts of those assets, except that the carrying amount of an individual asset shall not be reduced below its fair value. Calculating the fair value of the assets involves significant estimates and assumptions. These estimates and assumptions include, among others, projected future cash flows, risk-adjusted discount rates, future economic and market conditions, and the determination of appropriate market comparables. Changes in these factors and assumptions used can materially affect the amount of impairment loss recognized in the period the asset was considered impaired. The Company did no t record any impairment of long-lived assets as of December 31, 2023 and 2022.
Income Tax Expense | Income Tax Expense Income taxes are recorded using the liability method, under which deferred tax assets and liabilities are determined based on differences between the financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. Valuation allowances are recorded against deferred tax assets, including net operating losses and tax credits, when it is determined it is more-likely-than-not that some or all of the tax benefits will not be realized. The Company accounts for uncertain tax positions in accordance with the provisions of ASC Topic 740, Income Taxes. When uncertain tax positions exist, the Company recognizes the tax benefit of tax positions to the extent that the benefit would more likely than not be realized assuming examination by the taxing authority. The determination as to whether the tax benefit will more likely than not be realized is based upon the technical merits of the tax position as well as consideration of the available facts and circumstances. Interest and penalties related to unrecognized tax benefits, if any, are recorded as a component of income tax expense.
Revenue Recognition | Revenue Recognition The Company records revenue in accordance with ASC Topic 606 (“ASC 606”), Revenue from Contracts with Customers, whereby revenue is recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration expected to be received in exchange for those goods or services. A five-step model is used to achieve the core principle: (1) identify the customer contract, (2) identify the contract’s performance obligations, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations and (5) recognize revenue when or as a performance obligation is satisfied. The Company applies the five-step model to contracts when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. (a) Sale of Pharmaceutical Products The Company mainly sells its pharmaceutical products to distributors in the PRC, who ultimately sell the products to hospitals, other medical institutions and pharmacies. Revenue from the sale of pharmaceutical products is recognized at the point in time when control of the product is transferred to the customer, generally upon completion of quality inspection by the distributor after delivery of the pharmaceutical products. The Company records revenue for product sales, net of estimated product returns. Customers have limited return rights related only to the product damage or defect identified upon delivery of the product. The Company estimates the amount of product sales that may be returned and records the estimate as a reduction of revenue and a refund liability in the period the related product revenue is recognized. To date, actual returns have not differed materially from the Company’s estimates. Rebates are offered to distributors, consistent with pharmaceutical industry practices. The estimated amounts of unpaid or unbilled rebates are recorded as a reduction of revenue, if any. Estimated rebates are determined based on contracted rates and sales volumes and, to a lesser extent, distributor inventories. The Company regularly reviews the information related to these estimates and adjusts the amounts accordingly. The Company uses the expected value method to estimate the amount of consideration to which it will be entitled. The requirements on constraining estimates of variable consideration, i.e., when it is probable that a significant revenue reversal in the amount of cumulative revenue recognized will not occur when the associated uncertainty with the variable consideration is subsequently resolved, are applied and the expected future rebates are deducted from the trade receivables from the customers. The Company has applied the practical expedients under ASC 606 with regard to assessment of financing component and concluded that there is no significant financing component given that the period between delivery of goods and payment is generally one year or less. (b) License of Intellectual Property Revenue from a license agreement is recognized at a point in time when the control of the right to use the license is transferred to the customer. For licenses that are bundled with other promises, the Company utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time. Development or regulatory milestone payments, which are included in the transaction price to the extent that it is probable that a significant reversal of accumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. At the inception of each arrangement that includes milestone payments, the Company evaluates whether the milestones are considered probable of being achieved and estimates the amount to be included in the transaction price using the most likely amount method. Milestone payments that are not within the control of the Company, such as regulatory approvals, are not considered probable of being achieved until those approvals are received. At the end of each reporting period, the Company re-evaluates the probability of achievement of any milestones, and if necessary, adjusts its estimated transaction price on a cumulative catch-up basis. The Company did no t recognize any contract assets as of December 31, 2023 and 2022.
Deferred Revenue | Deferred Revenue Deferred revenue is recognized when a payment is received from a customer before the Company transfers the related goods or services. Deferred revenue is recognized as revenue when the Company performs under the contract (i.e., transfers control of the related goods or services to the customer). As of December 31, 2023, the Company’s deferred revenue balance was $39,000. Deferred revenue was $145,000 as of December 31, 2022 which has been recognized as revenue during the year ended December 31, 2023.
Cost of Revenue | Cost of Revenue Cost of revenue mainly consists of cost of sales representing direct and indirect costs incurred to bring the product to saleable condition. Cost of sales primarily consists of (i) raw material costs; (ii) staff costs for production employees; (iii) depreciation and amortization related to property and equipment and intangible assets used in production; (iv) taxes and surcharges; (v) transportation costs; and (vi) miscellaneous other costs.
Stock-Based Compensation | Stock-Based Compensation The Company measures the cost of employee, non-employee and director services received in exchange for an award of equity instruments based on the fair value of the award on the date of grant. For equity awards that only contain service conditions, the Company recognizes the related expense over the period during which the employee, non-employee or director is required to provide service in exchange for the award on a straight-line basis. The estimated fair value of equity awards that contain performance conditions is expensed over the term of the award once the Company has determined that it is probable that performance conditions will be satisfied. The cost is recognized with a corresponding increase in equity. Determining the fair value of stock-based awards at the grant date requires judgment. The Company uses the Black-Scholes option-pricing model to determine the fair value of stock options. The determination of the grant date fair value of options using an option-pricing model is affected by the Company’s assumptions regarding a number of variables including the fair value of its common stock, its expected common stock price volatility over the expected life of the options, expected term of the stock option, risk-free interest rates and expected dividends. The Company elected to account for forfeitures when they occur. For awards that do not ultimately vest because non-market performance or service conditions have not been met, no expense is recognized. Where awards include a market or non-vesting condition, the transactions are treated as vesting irrespective of whether the market or non-vesting condition is satisfied, provided that all other performance and service conditions are satisfied. Where the terms of an equity award are modified, a minimum expense is recognized as if the terms had not been modified if the original terms of the award are met. In addition, an expense is recognized for any modification that increases the total fair value of the stock-based payments or is otherwise beneficial to the employee as measured at the date of modification. Where an equity-settled award is cancelled, it is treated as if it had vested on the date of cancellation, and any expense not yet recognized for the award is recognized immediately. This includes any award where non-vesting conditions within the control of either the Company or the employee are not met. However, if a new award is substituted for the cancelled award and is designated as a replacement award on the date that it is granted, the cancelled and new awards are treated as if they were a modification of the original award, as described in the previous paragraph.
Acquired IPR&D | Acquired IPR&D The Company measures and recognizes asset acquisitions that are not deemed to be business combinations based on the cost to acquire the assets, which includes transaction costs. Goodwill is not recognized in asset acquisitions. In an asset acquisition, the cost allocated to acquired IPR&D with no alternative future use is charged to expense at the acquisition date. Refer to Note 7 — GNI USA Contributions under the Business Combination Agreement for a more detailed description.
Research and Development Expenses | Research and Development Expenses Research and development costs are expensed as incurred. Nonrefundable advance payments for goods or services used in research and development are initially deferred and capitalized in prepaid and other current assets. The capitalized amounts are then expensed as the related goods are delivered or services are performed, or until it is no longer expected that the goods or services will be delivered. Research and development costs consist of payroll and other personnel-related expenses, laboratory supplies and reagents, contract research and development services, materials, and consulting costs, as well as allocations of facilities and other overhead costs.
Selling and Marketing Expenses | Selling and Marketing Expenses Selling and marketing expenses primarily relate to sales of ETUARY and consist of conference expenses incurred from hosting academic conferences, seminars and symposia; promotional expenses associated with market education on ETUARY for its use in hospitals; and staff costs primarily consisting of salaries and benefits for in-house marketing and promotion staff.
General and Administrative Expenses | General and Administrative Expenses General and administrative expenses consist of (i) accounting, IT, legal, administrative, and other internal service staff costs; (ii) stock-based compensation representing share options granted to its functional employees; (iii) professional service fees, primarily for legal and accounting services; and (iv) other miscellaneous expenses.
Government Grants | Government Grants Government grants are recognized at their fair value where there is reasonable assurance that the grant will be received, and all attaching conditions will be complied with. When the grant relates to an expense item, it is recognized as income on a systematic basis over the periods that the costs, for which it is intended to compensate, are expensed. Where the grant relates to an asset, the fair value is credited to a deferred income account and is released to profit or loss over the expected useful life of the relevant asset by equal annual installments or deducted from the carrying amount of the asset and released to profit or loss by way of a reduced depreciation charge. Grant income is included within other income in the consolidated statements of operations and comprehensive (loss) income.
Interest Income | Interest Income Interest income is recognized on an accrual basis using the effective interest method by applying the rate that exactly discounts the estimated future cash receipts over the expected life of the financial instrument or a shorter period, when appropriate, to the net carrying amount of the financial asset.
Comprehensive Income (Loss) | Comprehensive Income (Loss) The Company is required to report all components of comprehensive income (loss), including net income (loss), in the accompanying consolidated financial statements in the period in which they are recognized. Comprehensive income (loss) is defined as the change in equity during a period from transactions and other events and circumstances from non-owner sources, including net income, unrealized gains and losses on investments and foreign currency translation adjustments.
Net Income (Loss) Per Share ("EPS") Attributable to Common Stockholders | Net Income (Loss) Per Share (“EPS”) Attributable to Common Stockholders The Company calculates basic and diluted EPS attributable to common stockholders in accordance with ASC Topic 260, Earnings per Share (“ASC 260”), which requires EPS for each class of stock (common stock and participating securities) to be calculated using the two-class method. The two-class method determines EPS for each class of common stock and participating securities according to dividends declared or accumulated and participation rights in undistributed earnings attributable to stockholders. The two-class method requires earnings available to common stockholders for the period to be allocated between common stock and participating securities based upon their respective rights to receive dividends as if all earnings for the period had been distributed. The Company’s Convertible Preferred Stock is classified as a participating security in accordance with ASC 260. The Convertible Preferred Stock contractually entitled the holders of such shares to participate in dividends but does not contractually require the holders of such shares to participate in the Company’s losses. As such, net losses attributable to stockholders for the periods presented were not allocated to these securities. Basic EPS is calculated by dividing net income or loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. Diluted EPS is computed by giving effect to all potentially dilutive securities outstanding for each period presented. For periods in which the Company reports net loss attributable to common stockholders, diluted EPS attributable to common stockholders is the same as basic EPS attributable to common stockholders since the effects of potentially dilutive securities are antidilutive. See Note 16 — EPS for more information.
Foreign Currency Translation and Remeasurement | Foreign Currency Translation and Remeasurement The functional currency of the Company is the US Dollar. The local currency of foreign operations, except for those in highly inflationary economies, generally are considered to be their functional currency. The functional currency of BC is RMB. The determination of the respective functional currency is based on the criteria stated in ASC Topic 830, Foreign Currency Matters. The Company uses the U.S. Dollar as its reporting currency. Assets and liabilities are translated at foreign exchange rates on the balance sheet date. Equity amounts are translated at historical exchange rates. Revenue and expenses are translated at the average foreign exchange rates. The effects of these translation adjustments are reported within accumulated other comprehensive income in the consolidated balance sheets and consolidated statements of convertible preferred stock and equity, with the translation gain (loss) shown as a separate component of other comprehensive income (loss) in the accompanying consolidated statements of operations and comprehensive (loss) income. During the year ended December 31, 2023, the Company had translation loss of $1.5 million. During the year ended December 31, 2022, the Company had translation loss of $4.9 million. Foreign currency gains and losses arising from transactions denominated in a currency other than the functional currency of the entity involved are included within other income (expense), net in the consolidated statements of operations and comprehensive (loss) income. The foreign currency transaction gains or losses for the years ended December 31, 2023 and 2022 were immaterial.
Foreign Currency Risk | Foreign Currency Risk The RMB is not a freely convertible currency. The State Administration for Foreign Exchange, under the authority of the People’s Bank of China, controls the conversion of RMB into other currencies.

Accounting Pronouncements Recently Adopted | Accounting Pronouncements Recently Adopted In May 2021, the FASB issued ASU 2021-04, Earnings Per Share (Topic 260), Debt—Modifications and Extinguishments (Subtopic 470-50), Compensation—Stock Compensation (Topic 718), and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options. The amendments in ASU 2021-04 provide guidance to clarify and reduce diversity in an issuer’s accounting for modifications or exchanges of freestanding equity-classified written call options (for example, warrants) that remain equity classified after modification or exchange. The amendments in this ASU 2021-04 are effective for all entities for fiscal years beginning after December 15, 2021, and interim periods within those fiscal years. The Company adopted ASU 2021-04 and related updates on January 1, 2022, and the adoption did not have a material impact on its consolidated financial statements. In August 2020, FASB issued ASU 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40) to simplify accounting for certain financial instruments. ASU 2020-06 eliminates the previous models that require separation of beneficial conversion and cash conversion features from convertible instruments and simplifies the derivative scope exception guidance pertaining to equity classification of contracts in an entity’s own equity. The amendments in this ASU are effective for public business entities for fiscal years beginning after December 15, 2021. The Company adopted ASU 2020-06 on January 1, 2022, and the adoption did not have a material impact on its consolidated financial statements. In October 2021, the FASB issued ASU 2021-08, Business Combinations – Accounting for Contract Assets and Contact Liabilities from Contracts with Customers. The guidance is intended to improve the accounting for acquired revenue contracts with customers in a business combination by addressing diversity in practice. The guidance requires an acquirer to recognize and measure contract assets and liabilities acquired in a business combination in accordance with ASC 606 as if they had originated the contracts, as opposed to at fair value on the acquisition date. The Company adopted ASU 2021-08 and related updates on January 1, 2023. The adoption of ASU 2021-08 had no impact on the consolidated financial statements. In November 2021, the FASB issued ASU 2021-10, Government Assistance (Topic 832) — Disclosures by Business Entities about Government Assistance. The amendments in this ASU require disclosures about transactions with a government that have been accounted for by analogizing to a grant or contribution accounting model to increase transparency about (1) the types of transactions, (2) the accounting for the transactions, and (3) the effect of the transactions on an entity’s financial statements. The amendments in this ASU are effective for all entities within their scope for financial statements issued for annual periods beginning after December 15, 2021. The Company adopted this standard as of January 1, 2022. The adoption of this ASU did not have any material impact on the Company’s consolidated financial statements.

This ASU also requires disclosure of the title and position of the individual identified as the CODM and an explanation of how the CODM uses the reported measures of a segment’s profit or loss in assessing segment performance and deciding how to allocate resources. The ASU is effective for annual periods beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Adoption of the ASU should be applied retrospectively to all prior periods presented in the financial statements. Early adoption is permitted. The Company plans to adopt annual requirements and related updates under ASU 2023-07 on January 1, 2024 and interim requirements under ASU 2023-07 on January 1, 2025. The Company is currently assessing the impact of adoption of this standard on its consolidated financial statements.
