Item 9A. Controls and Procedures. Disclosure Controls and Procedures We maintain disclosure controls and procedures (as defined in Rules 13a-15(e) or 15d-15(e) under the Exchange Act) that are designed to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is (1) recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms and (2) accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. As of December 31, 2022, our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Annual Report on Form 10-K. Our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Our principal executive officer and principal financial officer have concluded based upon the evaluation described above that, as of December 31, 2022, our disclosure controls and procedures were effective at the reasonable assurance level. We continue to review and document our disclosure controls and procedures, including our internal controls and procedures for financial reporting, and may from time to time make changes aimed at enhancing their effectiveness and to ensure that our systems evolve with our business. Management’s Annual Report on Internal Control Over Financial Reporting Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is a process designed under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America. As of December 31, 2022, our management assessed the effectiveness of our internal control over financial reporting using the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission, or COSO, in Internal Control-Integrated Framework (2017). Based on this assessment, management, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, concluded that, as of December 31, 2022, our internal control over financial reporting was effective based on those criteria. Changes in Internal Control Over Financial Reporting An evaluation was performed under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of any changes in our internal control over financial reporting that occurred during our last fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. That evaluation did not identify any change in our internal control over financial reporting, as such term is defined in Rules 13a-15 and 15(d)-15 promulgated under the Exchange Act, that occurred during our latest fiscal quarter and that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Opinion on the Financial Statements We have audited the accompanying consolidated balance sheets of Protara Therapeutics, Inc. (the “Company”) as of December 31, 2022 and 2021, the related consolidated statements of operations and comprehensive loss, changes in stockholders’ deficit and cash flows for each of the two years ended December 31, 2022, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2022, in conformity with U.S. generally accepted accounting principles. Basis for Opinion These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion. Critical Audit Matter The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the account or disclosure to which it relates. Valuation of Goodwill Description of the Matter As discussed in Note 2 to the consolidated financial statements, goodwill is assessed annually for impairment as of December 31, or more frequently if an event occurs or circumstances change that would indicate that it is more likely than not that the fair value of a reporting unit has declined below its carrying value. As a result of the annual impairment test, the Company determined the estimated fair value of the reporting unit was less than the carrying value and recorded a non-cash goodwill impairment expense in the statements of operations and comprehensive loss of $29.5 million. Auditing the Company’s quantitative impairment test for goodwill was especially complex and judgmental due to the significant estimation required in determining the fair value of the reporting unit. In particular, the fair value estimate was sensitive to the significant assumptions that require judgment including the amount and timing of expected future cash flows and the related discount rate. These assumptions are affected by such factors as expected future market or economic conditions and clinical trial and regulatory events. How We Addressed the Matter in Our Audit To test the estimated fair value of the reporting unit, our audit procedures included, among others, assessing the valuation methodology, evaluating the significant assumptions used to develop the projected financial information, and testing the underlying data used by the Company in its analysis. For example, we compared the projected financial information developed by management to current industry benchmarks and economic trends and evaluated the expected impacts of the Company’s ongoing operating strategies to develop its portfolio of therapies on the significant assumptions. We performed sensitivity analyses of the significant assumptions to evaluate the change in the fair value of the reporting unit resulting from changes in the assumptions. We also considered the relationship between the fair value of the reporting unit to the market capitalization of the Company. In addition, we involved our internal valuation specialists to assist in evaluating the methodology and significant assumptions applied in developing the fair value estimate. /s/ Ernst & Young LLP We have served as the Company’s auditor since 2021.

F- 6 Protara Therapeutics, Inc. Notes to Consolidated Financial Statements (amounts in thousands, except share and per share data) 1. Organization and Nature of the Business Overview Protara Therapeutics, Inc., and its consolidated subsidiaries (“Protara” or the “Company”), is a clinical-stage biopharmaceutical company committed to advancing transformative therapies for the treatment of cancer and rare diseases. Protara’s portfolio includes two development programs utilizing TARA-002, an investigational cell therapy in development for the treatment of lymphatic malformations, or LMs and non-muscle invasive bladder cancer, or NMIBC. The third program in the portfolio is Intravenous, or IV Choline Chloride, an investigational phospholipid substrate replacement therapy initially in development for patients receiving parenteral nutrition, or PN who have intestinal failure associated liver disease, or IFALD. On January 9, 2020, privately-held ArTara Subsidiary, Inc. (“Private ArTara”) and Protara Therapeutics, Inc. (formerly ArTara Therapeutics, Inc., formerly Proteon Therapeutics, Inc.) completed the merger and reorganization (the “Merger”), in accordance with the terms of the Agreement and Plan of Merger and Reorganization, dated September 23, 2019, (the “Merger Agreement”) by and among Protara Therapeutics, Inc., Private ArTara and REM 1 Acquisition, Inc., a wholly owned subsidiary of Protara Therapeutics, Inc (“Merger Sub”). Thereupon, Merger Sub merged with and into Private ArTara, with Private ArTara surviving as a wholly owned subsidiary of Protara Therapeutics, Inc. The Merger was structured as a reverse merger and Private ArTara was determined to be the accounting acquirer based on the terms of the Merger and other factors, and the post-merger company retained the name ArTara Therapeutics, Inc., which on May 11, 2020 was changed to Protara Therapeutics, Inc. In addition, concurrently with the execution of the Merger Agreement, Protara issued a private placement, whereby all of the outstanding shares of Protara Therapeutics, Inc.’s Series A Preferred Stock were converted into shares of Protara Therapeutics, Inc.’s common stock. Shares of the Company’s common stock commenced trading on The Nasdaq Capital Market under the new name and ticker symbol “TARA” as of market open on January 10, 2020. Liquidity, Capital Resources and Management Plans The Company is in the business of developing biopharmaceuticals and has no current or near-term revenues. The Company has incurred substantial clinical and other costs in its drug development efforts. The Company will need to raise additional capital in order to fully realize management’s plans. The Company believes that its current financial resources are sufficient to satisfy the Company’s estimated liquidity needs for at least twelve months from the date of issuance of these consolidated financial statements. Impact of the COVID-19 Pandemic As a result of the impacts of the COVID-19 pandemic, the Company has experienced delays and may experience additional future delays that impact the business, research and development activities, the healthcare systems in which the Company operates and the global economy as a whole. Due to the continued impact of the COVID-19 pandemic, the Company is not able to estimate the ongoing effects on the Company’s results of operations, financial condition, or liquidity. The Company will continue to monitor the impact of the COVID-19 pandemic and its related macroeconomic effects closely including whether the effects would have a material impact on the Company’s operations, liquidity and capital resources. F- 7 Protara Therapeutics, Inc. Notes to Consolidated Financial Statements (amounts in thousands, except share and per share data) 2. Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP” or “GAAP”). Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in the accompanying consolidated financial statements. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses, and related disclosure of contingent assets and liabilities at the date of the consolidated financial statements. Significant items subject to such estimates include but are not limited to income taxes, the valuation of deferred tax assets, recoverability of goodwill, and contingencies. On an ongoing basis, the Company’s management evaluates its estimates based on historical and anticipated results, trends, and various other assumptions believed to be reasonable. Actual results could differ from those estimates. The results of any changes in accounting estimates are reflected in the financial statements of the period in which the change becomes evident. Reclassification Certain amounts in prior periods related to the classification of accrued expenses and income taxes have been reclassified to conform to current period presentation. These reclassifications to adjust prior period presentation had no impact on consolidated statements of operations and comprehensive loss or consolidated statements of cash flows. Cash, Cash Equivalents and Restricted Cash The Company considers all highly liquid instruments with an original maturity of three months or less when acquired to be cash equivalents. Cash and cash equivalents are held in depository and money market accounts and are reported at fair value. The Company’s restricted cash balances consist of cash deposits to collateralize letter of credit obligations. F- 8 Protara Therapeutics, Inc. Notes to Consolidated Financial Statements (amounts in thousands, except share and per share data) The following table provides a reconciliation of cash, cash equivalents, and restricted cash in the consolidated balance sheets to the total amount shown in the consolidated statements of cash flows: December 31, 2022 2021 Cash and cash equivalents $ 24,127 $ 35,724 Restricted cash, non-current 745 745 Total cash, cash equivalents and restricted cash shown in the consolidated statements of cash flows $ 24,872 $ 36,469 Fair Value Measurements Accounting Standards Codification (“ASC”) Topic 820 “Fair Value Measurements” provides the framework for measuring fair value and establishes a fair value hierarchy that prioritizes the inputs used in pricing the asset or liability. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements). Fair value is defined as the exchange price, or an exit price, representing the amount that would be received upon the sale of an asset or payment to transfer a liability in an orderly transaction between market participants. As a basis for considering market participant assumptions in fair value measurements, the three-tier fair value hierarchy is used to prioritize the inputs in measuring fair value as follows: Ø Level 1 Quoted prices in active markets for identical assets or liabilities. Ø Level 2 Quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable, either directly or indirectly. Ø Level 3 Significant unobservable inputs that cannot be corroborated by market data. The carrying amounts of cash and cash equivalents, prepaid expenses and accounts payable approximate their fair values due to the short-term nature of these instruments. Marketable Debt Securities The Company classifies investments in marketable debt securities with remaining maturities when purchased of greater than three months as available-for-sale. Investments with a remaining maturity date greater than one year are classified as non-current. The cost of securities sold is based on the specific identification method. Interest and dividends earned on securities are classified as available-for-sale are included in investment income. The Company records investments at fair value with unrealized gains and losses recorded as a component of other comprehensive loss in the consolidated statements of operations and comprehensive loss until realized. Realized gains and losses are reflected in interest and investment income in the consolidated statements of operations and comprehensive loss and are determined using the specific identification method with transactions recorded on a settlement date basis. Fair value is determined based on quoted market rates when observable or utilizing data points that are observable, such as quoted prices, interest rates and yield curves. To determine whether an other-than-temporary impairment exists, the Company considers whether it has the ability and intent to hold the investment until a market price recovery, and whether evidence indicating the recoverability of the cost of the investment outweighs evidence to the contrary. The Company has the ability to hold such securities with an unrealized loss until its forecasted recovery. The Company determined that there was no material change in the credit risk of these investments. F- 9 Protara Therapeutics, Inc. Notes to Consolidated Financial Statements (amounts in thousands, except share and per share data) Concentrations of Credit Risk Financial instruments, which potentially subject the Company to concentrations of credit risk, consists principally of cash, cash equivalents, restricted cash, and marketable debt securities. The Company currently invests its excess cash primarily in money market funds and high quality, investment grade marketable debt securities of corporations. The Company has adopted an investment policy that includes guidelines relative to credit quality, diversification and maturities to preserve principal and liquidity. Property and Equipment, net Property and equipment, including leasehold improvements, are recorded at cost less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over the estimated useful life of the asset. Depreciation begins at the time the asset is placed in service. Leasehold improvements are amortized using the straight-line method over the shorter of the lease term or estimated useful life of the asset. Repairs and maintenance costs are expensed as incurred, whereas major improvements are capitalized as additions to property and equipment. The estimated useful lives for significant property and equipment categories are as follows: Asset Classification Estimated Useful Life Computer equipment 5 Furniture, fixtures and other 5 Laboratory equipment 7 Leasehold improvements Shorter of the useful life of asset or the lease term Leases The Company enters into contracts in the normal course of business and assesses whether any such contracts contain a lease. The Company determines if an arrangement is a lease at inception if it conveys the right to control the identified asset for a period of time in exchange for consideration. Under ASC 842, lease expense is recognized as a single lease cost on a straight-line basis over the lease term. The lease term consists of non-cancelable periods and may include options to extend or terminate the lease term, when it is reasonably certain such options will be exercised. Leases classified as operating leases are included in operating lease right-of-use (“ROU”) assets, current operating lease liabilities and noncurrent operating lease liabilities in our consolidated balance sheet. Finance leases are included in property and equipment and finance lease obligations, in our consolidated balance sheet. ROU assets represent the right to use an underlying asset for the lease term. Lease liabilities represent the present value of future lease payments, net of lease incentives, discounted using an incremental borrowing rate, which is a management estimate based on the information available at the commencement date of a lease arrangement. ROU assets and lease liabilities are recognized at the lease commencement date. The Company has elected to account for the lease and non-lease components for leases as a single component for classes of all underlying assets and allocate all the contract consideration to the lease component only. Lease cost for operating leases is recognized on a straight-line basis over the lease term and is included in operating expenses on the statements of operations and comprehensive loss. Variable lease payments are included in lease operating expenses. The Company recognizes costs associated with lease arrangements having an initial term of 12 months or less (“short-term leases”) on a straight-line basis over the lease term; such short-term leases are not recorded on the balance sheet. Impairment of Long-Lived Assets Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset or asset group may not be recoverable or that the useful life is shorter than originally estimated. When such events occur, the Company compares the carrying amounts of the asset or asset group to the undiscounted expected future cash flows. If this comparison indicates that the asset or asset group is impaired, the amount of impairment is measured as the difference between the carrying value and fair value of the asset or asset group. If the useful life is shorter than originally estimated, the Company will amortize the remaining carrying value over the new shorter useful life. To date, no such impairment loss has been recognized. F- 10 Protara Therapeutics, Inc. Notes to Consolidated Financial Statements (amounts in thousands, except share and per share data) Segment Information The Company identifies its operating segments in accordance with Accounting Standards Codification (“ASC”) 280, Segment Reporting (“ASC 280”). Operating segments are defined as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. The Company’s chief operating decision maker, its Chief Executive Officer, manages the Company’s operations on a consolidated basis for the purposes of allocating resources. Accordingly, the Company has determined it operates and manages its business in a single reportable operating segment . Goodwill On January 9, 2020, in connection with the Merger, the Company separately valued the assets and liabilities acquired, and then determined goodwill as the residual of the purchase price less identified net assets, resulting in the initial recording of $ 29.5 million in goodwill. Goodwill represents the excess of purchase price over the fair value of identifiable net assets acquired in a business combination. Goodwill has an indefinite useful life. Goodwill is assessed annually for impairment as of December 31, or more frequently if an event occurs or circumstances change that would indicate that it is more likely than not that the fair value of a reporting unit or the fair value of an indefinite-lived intangible asset has declined below its carrying value. In performing its annual goodwill impairment assessment, the Company has the option under GAAP to qualitatively assess whether it is more likely than not that the fair value of a reporting unit is less than its carrying value; if the conclusion of the qualitative assessment is that there are no indicators of impairment, the Company does not perform a quantitative assessment. Otherwise, a quantitative assessment is performed and the fair value of the reporting unit is determined. Goodwill is evaluated for impairment at the reporting unit level, which is defined as an operating segment, or one level below an operating segment. The Company has determined that it operates as one reporting unit and has selected December 31 as the date to perform its annual impairment test. As of December 31, 2022 and 2021, the Company elected to forego the qualitative screen and performed a quantitative annual goodwill impairment test for the reporting unit. As of December 31, 2022, the Company’s stock price and market capitalization declined 60 % from December 31, 2021, which reflects the overall decline of similar companies with less than $ 250 million in market capitalizations, or microcap companies. The life sciences sector, which includes pre-commercialization and therefore net operating loss generating companies, relies heavily on the capital markets to finance their operations and fund pre-clinical and clinical trials for their existing development programs. As a result of a shift in risk appetite in the overall financial markets, the availability of capital for life science sector companies decreased significantly in 2022. The challenging financing conditions had a negative impact on stock prices and respective market capitalizations, particularly for microcap companies. The Company considered the heightened financing risk that impacted the life sciences sector during 2022 to be one of the key macroeconomic factors that led to a sustained decrease in the Company’s stock price and market capitalization leading up to its annual goodwill impairment assessment date in late 2022. Based upon the results of our 2022 annual goodwill impairment test, the Company recorded a loss on impairment of goodwill of $ 29.5 million during the year ended December 31, 2022. The following table provides a roll forward of the Company’s goodwill and accumulated impairment losses. Goodwill Goodwill, gross amount as of December 31, 2021 $ 29,517 Accumulated impairment loss, as of December 31, 2021 - Goodwill as of December 31, 2021 29,517 Additions to goodwill - Loss on impairment ( 29,517 ) Goodwill as of December 31, 2022 $ - Based upon the results of our annual goodwill impairment test, no adjustments to the carrying value of goodwill were necessary during the year ended December 31, 2021. Research and Development Research and development expenses consist primarily of third-party costs incurred to develop drug candidates, employee-related expenses, including salaries, benefits, travel and stock-based compensation expense, depreciation and other allocated overhead costs, which include rent and maintenance of facilities and other supplies. Research and development costs are expensed as incurred. Before a compound receives regulatory approval, the Company records upfront and milestone payments made to third parties under licensing arrangements as expense provided that there is no alternative future use of the rights in other research and development projects. Nonrefundable advance payments to vendors for goods or services that will be used or received in future research and development activities are deferred and recognized as expense in the period in which the related goods are delivered or services are performed. Where milestone payments are due to third parties under research and development collaboration arrangements or other contractual agreements, the milestone payment obligations are expensed when the milestone conditions are met and the amount of payment is reasonably estimable. F- 11 Protara Therapeutics, Inc. Notes to Consolidated Financial Statements (amounts in thousands, except share and per share data) Once a compound receives regulatory approval, the Company records any milestone payments in identifiable intangible assets, less accumulated amortization and, unless the asset is determined to have an indefinite life, the Company amortizes the payments on a straight-line basis over the remaining agreement term or the expected product life cycle, whichever is shorter. Certain third-party costs are included as a component of research and development expense. These expenses include fees paid to contract research organizations (“CROs”) and other clinical trial costs, contractual services costs and costs for supply of its drug candidates. Depending upon the timing of payments to the service providers, the Company recognizes prepaid expenses or accrued expenses related to these costs. These accrued or prepaid expenses are based on management’s estimates of the work performed under service agreements, milestones achieved and experience with similar contracts. The Company monitors each of these factors and adjusts estimates accordingly. Patent Costs All patent-related costs incurred in connection with filing and prosecuting patent applications are expensed as incurred due to the uncertainty about the recovery of the expenditure. Amounts incurred are classified as general and administrative expenses. Interest and Investment Income Investment income consists primarily of interest income, accretion income earned and amortization expense incurred and realized gains or losses related to our marketable debt securities and interest income related to cash, cash equivalents and restricted cash. Stock-Based Compensation The Company’s stock-based compensation programs include stock options, restricted stock units (“RSUs”), and an employee stock purchase program (“ESPP”). The Company accounts for stock-based compensation using the fair value method. The Company measures all stock options and other stock-based awards granted to employees and directors based on the fair value on the date of the grant and recognizes compensation expense of those awards over the requisite service period, which is generally the vesting period of the respective award. The Company recognizes forfeitures at the time forfeitures occur. The fair value of each option is estimated on the date of grant using the Black-Scholes option-pricing model. Expected volatility for the Company’s common stock is determined based on an average of the historical volatility of the Company and the historical volatility of a peer-group of similar public companies. The expected term of options granted to employees is calculated using the simplified method, which represents the average of the contractual term of the option and the weighted-average vesting period of the option. The assumed dividend yield is based upon the Company’s expectation of not paying dividends in the foreseeable future. The risk-free interest rate is based upon the U.S. Treasury yield curve commensurate with the expected term at the time of grant or remeasurement. The stock-based compensation expense associated with purchase rights under the ESPP is measured at fair-value using a Black-Scholes option-pricing model at commencement of each offering period and recognized over that offering period. The Black-Scholes option pricing assumptions are similar to those used for stock options with the exception of the expected term of purchase rights for the ESPP which is based on the duration of an offering period. The fair values of RSUs are based on the fair market value of the Company’s common stock on the date of the grant. The RSUs are granted to directors pursuant to the Company’s equity plan. Settlement for the RSUs is deferred until the earliest to occur of (i) the director’s termination of service, (ii) death, (iii) disability or (iv) a change in control of the Company. In the event of a change in control of the Company, the RSUs will vest in full. The fair value of all stock-based awards is recognized as stock-based compensation expense on a straight-line basis over the vesting period, which is typically one to four years for RSUs and four years for stock options. The Company classifies stock-based compensation expense in its statement of operations and comprehensive loss in the same way the payroll costs or service payments are classified for the related stock-based award recipients. F- 12 Protara Therapeutics, Inc. Notes to Consolidated Financial Statements (amounts in thousands, except share and per share data) Income Taxes Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis, operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The measurement of net deferred tax assets is reduced by the amount of any tax benefit that, based on available evidence, is not expected to be realized, and a corresponding valuation allowance is established. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. Tax benefits are recognized only for tax positions that are more likely than not to be sustained upon examination by tax authorities. The amount recognized is measured as the largest amount of benefit that is greater than 50 percent likely to be realized upon settlement. A liability for unrecognized tax benefits is recorded for any tax benefits claimed in the Company’s tax returns that do not meet these recognition and measurement standards. The Company’s policy is to record interest and penalties on uncertain tax positions as a component of income tax expense in the consolidated statement of operations and comprehensive loss. Net Loss Per Share Attributable to Common Stockholders Basic net loss per share is computed by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by dividing net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period plus the common equivalent shares for the period including any dilutive effect from unvested restricted common stock, outstanding stock options and potential shares issuable under the ESPP. Recently Adopted Accounting Pronouncements In August 2018, the Financial Accounting Standards Board, or the FASB, issued ASU No. 2018-15, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (“ASU 2018-15”). This ASU is designed to reduce complexity for accounting for costs of implementing a cloud computing service arrangement. This standard aligns the accounting for implementation costs of hosting arrangements, regardless of whether they convey a license to the hosted software. The standard became effective for the first interim period within annual reporting periods beginning after December 15, 2020. On January 1, 2021, the Company adopted ASU 2018-15. The adoption of this standard did not have a material effect on the Company’s financial position, results of operations, or cash flows. In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”). The amendments in ASU 2019-12 remove certain exceptions to the general principles in Topic 740. The amendments also clarify and amend existing guidance to improve consistent application. The amendments became effective for annual reporting periods beginning after December 15, 2020. On January 1, 2021, the Company adopted ASU 2019-12. The adoption of this standard did not have a material effect on the Company’s financial position, results of operations, or cash flows. Recent Accounting Pronouncements Not Yet Adopted In June 2016, the Financial Accounting Standards Board, or the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Statements . The new standard requires that expected credit losses relating to financial assets measured on an amortized cost basis and available-for-sale debt securities be recorded through an allowance for credit losses. It also limits the amount of credit losses to be recognized for available-for-sale debt securities to the amount by which carrying value exceeds fair value and also requires the reversal of previously recognized credit losses if fair value increases. In November 2019, the FASB issued ASU 2019-10, Financial Instruments – Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates , which amended the effective date for certain companies. The standard is effective for public companies eligible to be smaller reporting companies for annual and interim periods beginning after December 15, 2022. Early adoption is available. The Company has evaluated the impact of the adoption of ASU 2016-13, and related updates, and has determined that the impact will not be material to its consolidated financial statements and disclosures. The Company has evaluated other recently issued accounting pronouncements and has concluded that the impact of recently issued standards that are not yet effective will not have a material impact on the Company’s financial position or results of operations upon adoption. F- 13 Protara Therapeutics, Inc. Notes to Consolidated Financial Statements (amounts in thousands, except share and per share data) Subsequent Events The Company evaluated subsequent events and transactions that occurred after the balance sheet date up to the date that the financial statements were available to be issued. Other than as described in Note 11 and, the Company did not identify any subsequent events that would have required adjustment or disclosure in the financial statements. 3. Fair Value of Financial Instruments The tables below present information about the Company’s financial instruments that are measured at fair value on a recurring basis as of December 31, 2022 and 2021 and indicates the fair value hierarchy of the valuation techniques the Company utilized to determine such fair value, as described under Note 2, Summary of Significant Accounting Policies. The following tables present the Company’s financial assets and liabilities that are measured and carried at fair value and indicate the level within the fair value hierarchy of the valuation techniques it utilizes to determine such fair value: December 31, 2022 Level 1 Level 2 Level 3 Total Cash Equivalents Money market funds (a) $ 13,284 $ - $ - $ 13,284 Corporate bonds (a) - 2,523 - 2,523 Restricted cash, non-current Money market funds (b) 745 - - 745 Marketable debt securities Corporate bonds (c) - 78,129 - 78,129 Total $ 14,029 $ 80,652 $ - $ 94,681 December 31, 2021 Level 1 Level 2 Level 3 Total Cash Equivalents Money market funds (a) $ 26,323 $ - $ - $ 26,323 Restricted cash, non-current Money market funds (b) 745 - - 745 Marketable debt securities Corporate bonds (c) - 94,972 - 94,972 Total $ 27,068 $ 94,972 $ - $ 122,040 (a) Money market funds and corporate debt securities with original maturities of 90 days or less are included within Cash and cash equivalents in the Consolidated Balance Sheets. (b) Restricted Money market funds are included within Restricted Cash, non-current in the Consolidated Balance Sheets. (c) Corporate debt securities with original maturities greater than 90 days are included within Marketable securities in the Consolidated Balance Sheets and classified as current or noncurrent based upon whether the maturity of the financial asset is less than or greater than 12 months. F- 14 Protara Therapeutics, Inc. Notes to Consolidated Financial Statements (amounts in thousands, except share and per share data) Money market funds are classified as Level 1 within the fair value hierarchy, because they are valued using quoted prices in active markets. Corporate debt securities classified as Level 2 within the fair value hierarchy are valued on the basis of prices from an orderly transaction between market participants provided by reputable dealers or pricing services. Prices of these securities are obtained through independent, third-party pricing services and include market quotations that may include both observable and unobservable inputs. In determining the value of a particular investment, pricing services may use certain information with respect to transactions in such investments, quotations from dealers, pricing matrices and market transactions in comparable investments and various relationships between investments. There were no transfers of financial instruments among Level 1, Level 2, and Level 3 during the period presented. Cash equivalents, prepaid expenses and other current assets, accounts payable and accrued expenses at December 31, 2022 and 2021 are carried at amounts that approximate fair value due to their short-term maturities. Non-Recurring Fair Value Measurements During the fourth quarter of 2022, the Company recorded a goodwill impairment loss of $ 29.5 million, refer to Note 2 for additional details on the impairment of goodwill. The fair value of our reporting unit was determined using an income approach based on discounted cash flows, or DCF. Determining fair value using a DCF analysis requires the exercise of significant judgment with respect to several assumptions and estimates, including the amount and timing of expected future cash flows and appropriate discount rate to be applied. The expected cash flows used in the DCF analysis are based on our most recent internal long-range forecast and budget and, for years beyond the budget, our estimates, which are based, in part, on industry benchmarks and forecasted growth rates. The discount rate used in the DCF analysis is intended to reflect the risks inherent in the expected future cash flows of the respective programs within our portfolio. The inputs to the DCF model are Level 3 valuation inputs. 4.

The Company is responsible for real estate taxes, maintenance and other operating expenses applicable to the leased premises which are recognized as variable lease expense in the period when incurred. In conjunction with the Office Lease, the Company established a letter of credit of approximately $ 745 secured by cash balances included in restricted cash. In June 2021, the Company amended the existing agreement with its contract development and manufacturing organization, or CDMO, establishing a term of eight-years from the amendment date.

The terms of the Series 1 Convertible Preferred Stock provide that, in the event of a fundamental transaction (as such term is described in the certificate of designation of preferences, rights and limitations of series 1 convertible non-voting preferred stock), each share of Series 1 Convertible Preferred Stock outstanding will thereafter be convertible into the kind and amount of securities, cash and/or other property which a holder of the number of shares of Common Stock of the Company issuable upon conversion of one share of Series 1 Convertible Preferred Stock immediately prior to such fundamental transaction would have been entitled to receive pursuant to such fundamental transaction, provided that, if the value of the aggregate of such securities, cash and/or other property the which the holder of one share of Series 1 Convertible Preferred Stock would be entitled to upon conversion thereof would be less than the stated value, then each outstanding share of Series 1 Convertible Preferred Stock will instead be convertible into such kind of securities, cash and/or other property with an aggregate value equal to the stated value. Each share of Series 1 Convertible Preferred Stock is entitled to a preference of $ 10.00 per share upon liquidation of the Company, and thereafter will share ratably in any distributions or payments on an as-converted basis with the holders of Common Stock.

For the year ended December 31, 2022, the Company’s effective tax rate was 0%, which consisted principally of a federal rate of 21%, the Company’s estimate of state taxes, net of federal benefit, of 2.2%, research and development credits of 3.3% and a true-up to the prior year’s tax return of 0.7%, offset by goodwill impairment of 10.4% and a valuation allowance 17.0%. As of December 31, 2022 and 2021 for U.S. federal and state income tax reporting purposes, the Company has approximately $ 114,800 and $ 100,200 , respectively, of unused net operating losses (“NOLs”) available for carry forward to future years. As a result of the Tax Cuts and Jobs Act of 2017 (“TCJA”), for U.S. income tax purposes, NOLs generated in tax years beginning before January 1, 2018 can still be carried forward for up to 20 years, but net operating losses generated for tax years beginning after December 31, 2017 carryforward indefinitely and can be used to offset taxable income. Of the total Federal NOL, $ 600 can be carried forward until 2037; and $ 114,200 can be carried forward indefinitely. The New York state and city NOLs may be carried forward through the year 2042 and may be applied against future taxable income. Further, the benefit from utilization of NOL carry forwards could be subject to limitations due to material ownership changes that could occur as the Company continues to issue additional shares of common stock pursuant to its capital raising plans. Based on such limitations, the Company has significant NOLs for which realization of tax benefits is uncertain. The Company has not performed a study to determine whether or not there is such a limitation. F- 25 Protara Therapeutics, Inc. Notes to Consolidated Financial Statements (amounts in thousands, except share and per share data) The Company remains subject to examination by tax authorities for all tax years. Based on a history of cumulative losses at the Company and the results of operations for the years ended December 31, 2022 and 2021, the Company determined that it is more likely than not that it will not realize benefits from the net deferred tax assets. The Company will not record income tax benefits in the financial statements until it is determined that it is more likely than not that the Company will generate sufficient taxable income to realize the deferred income tax assets. As a result of the analysis, the Company determined that a full valuation allowance against the deferred tax assets, net, was required. As of December 31, 2022 and 2021, the Company has recorded a valuation allowance of $ 39.0 million and $ 27.8 million, respectively. As of December 31, 2022 and 2021, management does not believe that the Company has any material uncertain tax positions that would require it to measure and reflect the potential lack of sustainability of a position on audit in its consolidated financial statements. The Company will continue to evaluate its uncertain tax positions in future periods to determine if measurement and recognition in its financial statements is necessary. The Company does not believe there will be any material changes in its unrecognized tax positions over the next year. 13. Employee Benefit Plan The Company maintains a defined contribution benefit plan under section 401(k) of the Internal Revenue Code covering substantially all qualified employees of the Company (the “401(k) Plan”). Under the 401(k) Plan, the Company matches 100 % of employee contributions up to 4 % of employee compensation. For the years ended December 31, 2022 and 2021, the Company recorded expense of $ 223 and $ 215 , respectively, representing employer contributions under the 401(k) Plan. 14. Net Loss per Common Share The following table sets forth the computation of the net loss per share attributable to common stockholders, basic and diluted: December 31, 2022 2021 Numerator: Net loss attributable to common stockholders $ 65,952 $ 47,252 Denominator: Weighted-average common shares outstanding – basic and diluted 11,259,615 11,232,576 Net loss per share attributable to common stockholders, basic and diluted $ ( 5.86 ) $ ( 4.21 ) Since the Company was in a net loss position for all periods presented, net loss per share attributable to common stockholders was the same on a basic and diluted basis, as the inclusion of all potential common equivalent shares outstanding would have been anti-dilutive. The Company excluded the following potential common shares, presented based on amounts outstanding at each period end, from the computation of diluted net loss per share attributable to common stockholders for the periods indicated because including them would have had an anti-dilutive effect: December 31, 2022 2021 Stock options issued and outstanding 1,828,329 1,356,639 Restricted stock units issued and outstanding 486,338 383,119 Conversion of Series 1 Convertible Preferred Stock 8,029,039 8,029,039 Total potentially dilutive shares 10,343,706 9,768,797 F-26
