AND ITS SUBSIDIARY Notes To Unaudited Condensed Consolidated Financial Statements Note 1 — Organization and Business Operation Description of business Estrella Immunopharma, Inc., a Delaware corporation, is a preclinical-stage biopharmaceutical company developing T-cell therapies with the capacity to cure patients with blood cancers and solid tumors. As further discussed below and in Note 3, on September 29, 2023 (the “ Closing Date ”), Estrella Biopharma, Inc. (“Estrella”) and TradeUP Acquisition Corp. (“UPTD”) consummated the business combination (the “Business Combination”) pursuant to the terms of the Agreement and Plan of Merger, dated as of September 30, 2022 (the “Merger Agreement”), by and among UPTD, Tradeup Merger Sub Inc., a Delaware corporation and wholly-owned subsidiary of UPTD (“Merger Sub”), and the Company. Pursuant to the terms of the Merger Agreement, Merger Sub merged with and into Estrella, with Estrella surviving as a wholly-owned subsidiary of UPTD. Upon closing of the Business Combination (the “Closing”), UPTD changed its corporate name to Estrella Immunopharma, Inc. (“New Estrella” or the “Company”). Estrella was incorporated in the State of Delaware on March 30, 2022 by Eureka Therapeutics, Inc. (“Eureka”), which was incorporated in California in February 2006 and reincorporated in Delaware in March 2018 and is the predecessor of Estrella. Estrella’s fiscal year end is June 30, and the Company’s fiscal year end changed from December 31 to June 30 effective as of the Closing Date. On June 28, 2022, pursuant to a Contribution Agreement between Estrella and Eureka (the “Contribution Agreement”), Eureka contributed certain assets (the “Assets”) related to T-cell therapies targeting CD19 and CD22, proteins expressed on the surface of almost all B-cell leukemias and lymphomas, in exchange for 105,000,000 shares of Estrella’s Series AA Preferred Stock (the “Separation”). As part of the Separation, Estrella entered into a License Agreement (the “License Agreement”) with Eureka and Eureka Therapeutics (Cayman) Ltd. (“Eureka Cayman”), an affiliate of Eureka, and a Services Agreement (the “Services Agreement”) with Eureka, and Eureka contributed and assigned the Collaboration Agreement between Eureka and Imugene Limited (“Imugene”) (the “Collaboration Agreement”) to Estrella. The License Agreement grants the Company an exclusive license to develop CD19 and CD22 targeted T-cell therapies using Eureka’s ARTEMIS ® platform. Under the Services Agreement, Eureka has agreed to perform certain services for the Company in connection with the development of the Company’s product candidates, EB103 and EB104. EB103, which is a T-cell therapy also called “CD19-Redirected ARTEMIS ® T-Cell Therapy,” utilizes Eureka’s ARTEMIS ® technology to target CD19. The Company is also developing EB104, a T-cell therapy also called “CD19/22 Dual-Targeting ARTEMIS ® T-Cell Therapy.” Like EB103, EB104 utilizes Eureka’s ARTEMIS ® technology to target not only CD19, but also CD22. The Collaboration Agreement establishes the partnership between the Company and Imugene related to development of solid tumor treatments using Imugene’s product candidate (“CF33-CD19t”) in conjunction with EB103. The Company is in the development stage, having not yet started planned principal operations. As of December 31, 2023, the Company had devoted substantially all of its efforts toward preparing regulatory filings (including Investigational New Drug (“IND”) applications), planning preclinical studies, and building its management team. On March 2, 2023, the FDA cleared the IND for EB103, allowing Estrella to proceed with the Phase I/II Starlight-1 Clinical Trial, which the Company expects to commence in the first half of 2024. Merger and reverse recapitalization As described above and further discussed in Note 3, the Business Combination was consummated on September 29, 2023. The Business Combination was accounted for as a “reverse recapitalization”. Under this method of accounting, UPTD was treated as the “acquired” company for financial reporting purposes. Accordingly, the Business Combination was treated as the equivalent of Estrella issuing shares for the net assets of UPTD, accompanied by a recapitalization. The net assets of UPTD are stated at historical costs. No goodwill or other intangible assets are recorded. 5 ESTRELLA IMMUNOPHARMA, INC. AND ITS SUBSIDIARY Notes To Unaudited Condensed Consolidated Financial Statements Liquidity The accompanying unaudited condensed consolidated financial statements have been prepared on a basis which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. As of December 31, 2023, the Company had cash of approximately $ 9.0 million, and accumulated deficit of approximately $ 15.1 million. For the six months ended December 31, 2023, loss from operations was approximately $ 2.9 million. The Company’s ability to fund its operations is dependent on the amount of cash on hand and its ability to raise debt or additional equity financing. The Company has expended substantial funds on its research and development business, has experienced losses and negative cash flows from operations since its inception and expects losses and negative cash flows from operations to continue until its technology receives regulatory approval and the Company generates sufficient revenue and positive cash flow from operations, if ever. On September 29, 2023, the Business Combination and several concurrent financing transactions were consummated, with the Company receiving net proceeds of approximately $ 20.1 million, after deducting $ 5.1 million payable to redeem 467,122 shares of UPTD Common Stock at $ 10.86 per share in connection with the special meeting of UPTD stockholders related to the Business Combination held on July 31, 2023, $ 1.6 million for UPTD’s transaction expenses and $ 0.7 million for repayment of working capital loans, consisting of: (i) $ 9.75 million from the issuance of shares of the Company’s Operating Series A Preferred Stock immediately prior to the closing of the Business Combination ($ 0.7 million of which was comprised of funds in the trust account delivered to the Company at the closing of the Business Combination that would have otherwise been paid to US Tiger Securities, Inc. as a deferred underwriting fee in connection with UPTD’s IPO); (ii) $ 0.3 million from the issuance of an unsecured promissory note by us to a third party investor; (iii) $ 3.06 million from the funds held in UPTD’s trust account; and (iv) $ 10 million from the PIPE investors pursuant to the Subscription Agreements. On April 20, 2023, UPTD entered into the Common Stock Purchase Agreement and the White Lion RRA with White Lion. Subsequently, on April 26, 2023, UPTD and White Lion entered into an amendment to the Common Stock Purchase Agreement. Pursuant to the Common Stock Purchase Agreement, following the Closing, New Estrella will have the right, but not the obligation, to require White Lion to purchase, from time to time up to $ 50,000,000 in aggregate gross purchase price of newly issued shares of Common Stock (the “Equity Line Shares”), subject to certain limitations and conditions set forth in the Common Stock Purchase Agreement as further described in Note 8. On October 10, 2023, the Company used a portion of the net proceeds from the Business Combination to pay $ 8.3 million due to Eureka under the Services Agreement and approximately $ 0.9 million aggregate amount due to Eureka under the License Agreement, comprised of the outstanding portion of the upfront fee as well as a milestone payment in connection with the submission of the IND application for EB103. The Company intends to devote the remaining net proceeds from the Business Combination to the preclinical and clinical development of the Company’s product candidates and the public company compliance costs. The Company’s future operations are highly dependent on a combination of factors, including but not necessarily limited to (1) the success of our research and development programs; (2) the timely and successful completion of any additional financing; (3) the development of competitive therapies by other biotechnology and pharmaceutical companies; (4) our ability to manage growth of the organization; (5) our ability to protect our technology and products; and, ultimately (6) regulatory approval and successful commercialization and market acceptance of our product candidates. 6 ESTRELLA IMMUNOPHARMA, INC. AND ITS SUBSIDIARY Notes To Unaudited Condensed Consolidated Financial Statements However, management believes that the Company has sufficient funds and available credit line to meet its working capital requirements and debt obligations, for at least the next 12 months from the filing date of these unaudited condensed consolidated financial statements. Note 2 — Significant accounting policies Basis of Presentation The accompanying unaudited financial statements are presented in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). The accompanying unaudited financial statements have been prepared on the same basis as the annual financial statements and, in the opinion of management, reflect all adjustments, including normal recurring accruals, necessary to present fairly the Company’s consolidated financial statements. The results for the three and six months ended December 31, 2023 are not necessarily indicative of the results to be expected for the fiscal year ending June 30, 2024 (fiscal year 2024) or for any other interim period or for any future year. Principles of consolidation The unaudited condensed consolidated financial statements include the financial statements of the Company and its subsidiary. All transactions and balances among the Company and its subsidiary have been eliminated upon consolidation. A subsidiary is an entity in which the Company, directly or indirectly, controls more than one half of the voting power; or has the power to govern the financial and operating policies, to appoint or remove the majority of the members of the board of directors, or to cast a majority of votes at the meeting of directors. Emerging Growth Company Status The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act of 1933, as amended, (the “Securities Act”), as modified by the Jumpstart The Company’s Business Startups Act of 2012, (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such an election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s unaudited condensed consolidated financial statements with another public company difficult because of the potential differences in accounting standards used. Use of Estimates The preparation of unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. 7 ESTRELLA IMMUNOPHARMA, INC. AND ITS SUBSIDIARY Notes To Unaudited Condensed Consolidated Financial Statements Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the unaudited condensed consolidated financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates. Significant items subject to such estimates and assumptions include stock-based compensation, and deferred income tax asset valuation and allowances. Cash The Company maintains its operating accounts in a single financial institution. The balance is insured by the United States Federal Deposit Insurance Corporation (“FDIC”) but only up to specified limits. The Company’s cash is maintained in a checking and a saving account and Certificates of Deposits. Basic and Diluted Loss per Common Stock Basic net loss per Common Stock is calculated by dividing the net loss by the weighted–average number of Common Stock outstanding for the period. Diluted net loss per share is computed by dividing the net loss by the weighted–average number of Common Stock and dilutive share equivalents outstanding for the period, determined using the treasury stock and if–converted methods. Since the Company has had net losses for all periods presented, all potentially dilutive securities are anti–dilutive. As of December 31, 2023 and June 30, 2023, the Company had the following potential Common Stock outstanding which were not included in the calculation of diluted net loss per Common Stock because inclusion thereof would be anti-dilutive: As of As of December 31, June 30, 2023 2023 (Unaudited) Series A Preferred Stock* - 1,203,695 Series AA Preferred Stock* - 25,277,591 Unvested early-exercised stock option* - 2,633,082 Public warrant 2,215,000 - Total 2,215,000 29,114,368 * Giving retroactive effect to reverse recapitalization effected on September 29, 2023 to reflect exchange ratio of approximately 0.2407 as described in Note 3 Stock-Based Compensation The Company recognizes compensation costs resulting from the issuance of stock-based awards to employees, non-employees and directors as an expense in the statements of operations over the requisite service period based on a measurement of fair value for each stock-based award. The fair value of each option granted is estimated as of the date of grant using the Black-Scholes-Merton option-pricing model, net of actual forfeitures. The fair value is amortized as compensation cost on a straight-line basis over the requisite service period of the awards, which is generally the vesting period. The Black-Scholes-Merton option-pricing model includes various assumptions, including the fair market value of the Common Stock of the Company, expected life of stock options, the expected volatility and the expected risk-free interest rate, among others. These assumptions reflect the Company’s best estimates, but they involve inherent uncertainties based on market conditions generally outside the control of the Company. 8 ESTRELLA IMMUNOPHARMA, INC. AND ITS SUBSIDIARY Notes To Unaudited Condensed Consolidated Financial Statements As a result, if other assumptions had been used, stock-based compensation expense, as determined in accordance with authoritative guidance, could have been materially impacted. Furthermore, if the Company uses different assumptions on future grants, stock-based compensation expense could be materially affected in future periods. Mezzanine Equity Mezzanine equity represents the Series A Preferred Stock and Series AA Preferred Stock (collectively known as “Preferred Stock”) issued by the Company. The shares of Preferred Stock are mandatorily redeemable upon the occurrence of Deemed Liquidation Events outside of the Company’s control. Therefore, the Company classifies the Preferred Stock as mezzanine equity. Refer to Note 12. Warrants The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in Financial Accounting Standards Board (“FASB”) ASC 480, Distinguishing Liabilities from Equity (“ASC 480”) and ASC 815, Derivatives and Hedging (“ASC 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the Company’s own ordinary shares and whether the warrant holders could potentially require “net cash settlement” in a circumstance outside of the Company’s control, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding. For issued or modified warrants that meet all of the criteria for equity classification, the warrants are required to be recorded as a component of equity at the time of issuance. The Company determined that upon further review of the warrant agreements, the Company concluded that its warrants qualify for equity accounting treatment. Upon completion of the business combination, all of UPTD’s public warrants remain outstanding were replaced by the Company’s public warrants. The Company treated such warrants replacement as a warrant modification and no incremental fair value was recognized. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentration of credit risk consist of two cash accounts in a financial institution located in the United States. The Company has not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts. FDIC provides standard insurance coverage of $ 250,000 per insured bank, for each account ownership category. As of December 31, 2023 and June 30, 2023, the Company had not experienced losses on these accounts. As of December 31, 2023 and June 30, 2023, $ 9,046,015 and $ 2,479,146 were deposited with financial institutions located in the United States, and $ 8,784,872 and $ 2,229,146 of these balances are not covered by deposit insurance, respectively. While management believes that these financial institutions are of high credit quality, it also continually monitors their credit worthiness. Risks and Uncertainties Management continues to evaluate the impact of inflation rates, the continuing military action in Ukraine, and Israel’s war against Hamas on the industry and has concluded that these factors could have a negative effect on the Company’s financial position and/or results of its operations. The specific impact of these factors is not readily determinable as of the date of these unaudited condensed consolidated financial statements. The unaudited condensed consolidated financial statements do not include any adjustments that might result from the outcome of these uncertainties. 9 ESTRELLA IMMUNOPHARMA, INC. AND ITS SUBSIDIARY Notes To Unaudited Condensed Consolidated Financial Statements The Company’s future success depends on the Company and Eureka’s ability to retain key employees, directors, and advisors and to attract, retain and motivate qualified personnel. The Company relies on Eureka to provide certain technical assistance to facilitate the Company’s exploitation of the intellectual property licensed by Eureka, and Eureka will be solely responsible for the manufacture and supply of clinical quantities of the licensed products and final filled and finished (including packaged) drug product form of the licensed products. Pursuant to the Services Agreement, Eureka currently performs or supports the Company’s important research and development activities. The Services Agreement (see Note 10) may be terminated by mutual agreement at any time. Following the termination of, or the expiration of the term of, the Services Agreement, the Company may not be able to replace the research and development-related services that Eureka provides or enter into appropriate third-party arrangements on terms and conditions, including cost, comparable to those that the Company will receive from Eureka. Additionally, after the Services Agreement terminates, the Company may be unable to sustain the research and development-related services at the same levels or obtain the same benefits as when the Company was receiving such services and benefits from Eureka. If the Company is required to operate these research and development functions separately in the future, or are unable to obtain them from other providers, the Company may not be able to operate the Company’s business effectively and could result in a material adverse effect. The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC Topic 820, “Fair Value Measurements and Disclosures,” approximates the carrying amounts represented in the accompanying balance sheet, primarily due to their short-term nature. The Company measures the fair value of certain of its financial assets and liabilities on a recurring basis. A fair value hierarchy is used to rank the quality and reliability of the information used to determine fair values. Financial assets and liabilities carried at fair value which is not equivalent to cost will be classified and disclosed in one of the following three categories: Level 1 — Quoted prices (unadjusted) in active markets for identical assets and liabilities. Level 2 — Inputs other than Level 1 that are observable, either directly or indirectly, such as unadjusted quoted prices for similar assets and liabilities, unadjusted quoted prices in the 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. Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Income Taxes The Company recognizes deferred tax assets and liabilities for both the expected impact of differences between the financial statement and tax basis of assets and liabilities and for the expected future tax benefit to be derived from tax loss and tax credit carry forwards and establishes a valuation allowance when it is more likely than not that all or a portion of deferred tax assets will not be realized. Accounting for uncertainty in income taxes is recognized based on a recognition threshold and measurement process for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of December 31, 2023 and June 30, 2023. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company may be subject to potential examination by federal and state taxing authorities in the areas of income taxes. These potential examinations may include questioning the timing and amount of deductions, the nexus of income among various tax jurisdictions and compliance with federal and state tax laws. The Company’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months. The Company is incorporated in the State of Delaware and is required to pay franchise taxes to the State of Delaware on an annual basis. There is no tax sharing agreement with Eureka; therefore, no deferred taxes were carried over from Eureka to the Company. 10 ESTRELLA IMMUNOPHARMA, INC. AND ITS SUBSIDIARY Notes To Unaudited Condensed Consolidated Financial Statements Research and Development Expenses The Company charges research and development costs to operations as incurred. The Company accrues for costs incurred by external service providers, including contract research organizations and clinical investigators, based on its estimates of service performed and costs incurred. These estimates include the level of services performed by third parties, patient enrollment in clinical trials when applicable, administrative costs incurred by third parties, and other indicators of the services completed. Based on the timing of amounts invoiced by service providers, the Company may also record payments made to those providers as prepaid expenses that will be recognized as expense in future periods as the related services are rendered. Research and development expenses for the six months ended December 31, 2023 and 2022 primarily consisted of personnel costs for the design and development of clinical trials, legal and professional fees, facilities related fees and enhancement of the Company’s technology which was mainly performed by Eureka. (Refer to Note 10 for the terms of the License Agreement and the Service Agreement). Deferred transaction costs Deferred transaction costs consist primarily of expenses paid to attorneys, consultants, underwriters, and others related to the Merger. Should the Merger prove to be unsuccessful, these deferred costs, as well as additional expenses to be incurred, will be charged to expenses. Lease Effective July 1, 2022, the Company adopted ASU 2016-02, “Leases” (Topic 842), and elected the practical expedients that does not require us to reassess: (1) whether any expired or existing contracts are, or contain, leases, (2) lease classification for any expired or existing leases and (3) initial direct costs for any expired or existing leases. For lease terms of twelve months or fewer, a lessee is permitted to make an accounting policy election not to recognize lease assets and liabilities. If any of the following criteria are met, the Company classifies the lease as a finance lease: ● The lease transfers ownership of the underlying asset to the lessee by the end of the lease term; ● The lease grants the lessee an option to purchase the underlying asset that the Company is reasonably certain to exercise; ● The lease term is for a major part of the remaining economic life of the underlying asset; ● The present value of the sum of the lease payments and any residual value guaranteed by the lessee, that is not otherwise included in the lease payments substantially exceeds all of the fair value of the underlying asset; or ● The underlying asset is of such a specialized nature that it is expected to have no alternative use to the lessor at the end of the lease term. Leases that do not meet any of the above criteria are accounted for as operating leases. The Company combines lease and non-lease components in its contracts under Topic 842, when permissible. Operating lease right-of-use (“ROU”) asset and lease liability were recognized at the adoption date of July 1, 2022, based on the present value of lease payments over the lease term. Since the implicit rate for the Company’s leases is not readily determinable, the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The incremental borrowing rate is the rate of interest that the Company would have to pay to borrow, on a collateralized basis, an amount equal to the lease payments, in a similar economic environment and over a similar term. In the event of lease modification, the Company followed ASC 842-10-25 through 25-12, “lessee accounting for a modification that is not accounted for as a separate contract,” to remeasure and reallocate the remaining consideration in the lease agreement, and reassess the classification of the lease at the effective date of the modification. The Company reviews the impairment of its ROU asset consistent with the approach applied for its other long-lived assets. The Company reviews the recoverability of its long-lived assets when events or changes in circumstances occur that indicate that the carrying value of the asset may not be recoverable. The assessment of possible impairment is based on its ability to recover the carrying value of the asset from the expected undiscounted future pre-tax cash flows of the related operations. The Company has elected to include the carrying amount of operating lease liability in any tested asset group and includes the associated operating lease payments in the undiscounted future pre-tax cash flows. 11 ESTRELLA IMMUNOPHARMA, INC. AND ITS SUBSIDIARY Notes To Unaudited Condensed Consolidated Financial Statements Segment reporting The Company accounted for segment reporting in accordance with ASC 280, “Segment Reporting”. Based on qualitative and quantitative criteria established by ASC 280, the Company considers itself to be operating within one reportable segment. Recent Accounting Pronouncements The Company considers the applicability and impact of all accounting standards updates (“ASUs”). Management periodically reviews new accounting standards that are issued. Under the Jumpstart Our Business Startups Act of 2012, as amended (the “JOBS Act”), the Company meets the definition of an emerging growth company and has elected the extended transition period for complying with new or revised accounting standards, which delays the adoption of these accounting standards until they would apply to private companies. In July 2023, the FASB issued ASU 2023-03, “Presentation of Financial Statements (Topic 205), Income Statement—Reporting Comprehensive Income (Topic 220), Distinguishing Liabilities from Equity (Topic 480), Equity (Topic 505), and Compensation—Stock Compensation (Topic 718): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 120, SEC Staff Announcement at the March 24, 2022 EITF Meeting, and Staff Accounting Bulletin Topic 6.B, Accounting Series Release 280—General Revision of Regulation S-X: Income or Loss Applicable to Common Stock” (“ASU 2023-03”). This ASU amends or supersedes various SEC paragraphs within the applicable codification to conform to past SEC staff announcements. This ASU does not provide any new guidance. ASU 2023-03 will become effective for the Company once the addition to the FASB Codification is made available. The Company is currently evaluating the impact of the update on the Company’s consolidated financial statements and related disclosures. In October 2023, the FASB issued ASU 2023-06, Disclosure Improvements — codification amendments in response to SEC’s disclosure Update and Simplification initiative which amend the disclosure or presentation requirements of codification subtopic 230-10 Statement of Cash Flows—Overall, 250-10 Accounting Changes and Error Corrections— Overall, 260-10 Earnings Per Share— Overall, 270-10 Interim Reporting— Overall, 440-10 Commitments—Overall, 470-10 Debt—Overall, 505-10 Equity—Overall, 815-10 Derivatives and Hedging—Overall, 860-30 Transfers and Servicing—Secured Borrowing and Collateral, 932-235 Extractive Activities— Oil and Gas—Notes to Financial Statements, 946-20 Financial Services— Investment Companies— Investment Company Activities, and 974-10 Real Estate—Real Estate Investment Trusts—Overall. The amendments represent changes to clarify or improve disclosure and presentation requirements of above subtopics. Many of the amendments allow users to more easily compare entities subject to the SEC’s existing disclosures with those entities that were not previously subject to the SEC’s requirements. Also, the amendments align the requirements in the Codification with the SEC’s regulations. For entities subject to existing SEC disclosure requirements or those that must provide financial statements to the SEC for securities purposes without contractual transfer restrictions, the effective date aligns with the date when the SEC removes the related disclosure from Regulation S-X or Regulation S-K. Early adoption is not allowed. For all other entities, the amendments will be effective two years later from the date of the SEC's removal. The Company is currently evaluating the impact of the update on the Company’s consolidated financial statements and related disclosures. In December 2023, the FASB issued ASU 2023-09, which is an update to Topic 740, Income Taxes. The amendments in this update related to the rate reconciliation and income taxes paid disclosures improve the transparency of income tax disclosures by requiring (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction. The amendments allow investors to better assess, in their capital allocation decisions, how an entity’s worldwide operations and related tax risks and tax planning and operational opportunities affect its income tax rate and prospects for future cash flows. The other amendments in this Update improve the effectiveness and comparability of disclosures by (1) adding disclosures of pretax income (or loss) and income tax expense (or benefit) to be consistent with U.S. Securities and Exchange Commission (SEC) Regulation S-X 210.4-08(h), Rules of General Application—General Notes to Financial Statements: Income Tax Expense, and (2) removing disclosures that no longer are considered cost beneficial or relevant. For public business entities, the amendments in this Update are effective for annual periods beginning after December 15, 2024. For entities other than public business entities, the amendments are effective for annual periods beginning after December 15, 2025. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. The amendments in this Update should be applied on a prospective basis. Retrospective application is permitted. The Company is currently evaluating the impact of the update on Company’s consolidated financial statements and related disclosures. The Company does not believe recently issued but not yet effective accounting standards, if currently adopted, would have a material effect on the Company’s condensed consolidated financial statements.

Lease On July 6, 2022, Estrella entered into an office lease contract with Eureka, to lease a 428 square feet office with a $ 2,000 payment. Under the original lease contract, the sublease agreement commenced on August 1, 2022 and expired on September 30, 2023. In November 2022, the sublease’s expiration date was amended to July 31, 2023. Therefore, such lease contained a lease term for 12 months and less after amendment. Estrella elected not to apply the ROU and lease liability recognition requirements to above mentioned short-term lease as the modified lease term was less than twelve months.

The Company’s expected volatility was based upon the implied volatility of a portfolio of comparable companies. The expected life of the Company’s options was determined using the actual remaining life of the stock option. The fair value of the Common Stock input was determined by the board of directors based on a variety of factors, including valuation prepared by a third party, the Company’s financial position, the status of development efforts within the Company, the current climate in the marketplace and the prospects of a liquidity event, among others.
