Item 9 A. Controls and Procedures. Evaluation of Disclosure Controls and Procedures We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our periodic and current reports that we file with the SEC is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable and not absolute assurance of achieving the desired control objectives. In reaching a reasonable level of assurance, management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. In addition, the design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected. As of December 31, 2020, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of December 31, 2020. Management’s Report on Internal Control over Financial Reporting Our management is responsible for establishing and maintaining adequate internal control over financial reporting as such term as defined in Exchange Act Rule 13a-15(f). Internal control over financial reporting is a process designed under the supervision and with the participation of our management, including our principal executive officer and principal 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, 2020, 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 in Internal Control-Integrated Framework (2013 Framework). Based on this assessment, our management concluded that, as of December 31, 2020, our internal control over financial reporting was effective based on those criteria. Changes in Internal Control over Financial Reporting There were no changes in our internal control over financial reporting that occurred during the quarter ended December 31, 2020 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm F-2 Consolidated Balance Sheets F-3 Consolidated Statements of Operations and Comprehensive Loss F-4 Consolidated Statements of Stockholders’ Equity F-5 Consolidated Statements of Cash Flows F-6 Notes to Consolidated Financial Statements F-7 F-1 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Stockholders and Board of Directors Equillium, Inc.: Opinion on the Consolidated Financial Statements We have audited the accompanying consolidated balance sheets of Equillium, Inc. and its subsidiary (the Company) as of December 31, 2020 and 2019, the related consolidated statements of operations and comprehensive loss, stockholders’ equity, and cash flows for the years then ended, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the years then ended, in conformity with U.S. generally accepted accounting principles. Basis for Opinion These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. 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 consolidated 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 consolidated 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 consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion. /s/ KPMG LLP We have served as the Company’s auditor since 2018. San Diego, California March 24, 2021 F-2 Equillium, Inc.

From inception through December 31, 2020, the Company has devoted substantially all of its efforts to organizing and staffing the Company, business planning, raising capital, in-licensing rights to itolizumab (EQ001), conducting preclinical research, filing three initial Investigational New Drug applications (INDs), conducting clinical development of the Company’s initial product candidate, itolizumab (EQ001), conducting business development activities, and the general and administrative activities associated with operating as a public company. In addition, the Company has a limited operating history, has not generated revenues from its principal operations, and the sales and income potential of its business is unproven. Liquidity and Business Risks As of December 31, 2020, the Company had $82.2 million in cash, cash equivalents and short-term investments. The Company has incurred significant operating losses and negative cash flows from operations. The Company expects to use its cash, cash equivalents, and short-term investments to fund research and development of itolizumab (EQ001) and for working capital and other general corporate purposes. The Company does not expect to generate any revenues from product sales unless and until the Company successfully completes development and obtains regulatory approval of itolizumab (EQ001) or any future product candidate, which is unlikely to happen within the next 12 months, if ever. Accordingly, until such time as the Company can generate significant revenue from sales of its product candidates, if ever, the Company expects to finance its cash needs through a combination of equity offerings, debt financings, and collaboration and license agreements. However, the Company may not be able to secure additional financing or enter into such other arrangements in a timely manner or on favorable terms, if at all. As a result of the COVID-19 pandemic and actions taken to slow its spread, the global credit and financial markets have experienced extreme volatility, including diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth, increases in unemployment rates and uncertainty about economic stability. There can be no assurance that further deterioration in credit and financial markets and confidence in economic conditions will not occur. If equity and credit markets deteriorate, it may make any necessary debt or equity financing more difficult to obtain, more costly and/or more dilutive. The Company’s failure to raise capital or enter into such other arrangements when needed would have a negative impact on the Company’s financial condition and could force the Company to delay, reduce or terminate its research and development programs or other operations, or grant rights to develop and market product candidates that the Company would otherwise prefer to develop and market itself. Management believes that the Company’s cash, cash equivalents and short-term investments as of December 31, 2020 will be sufficient to fund operations for at least the next 12 months from the date this Annual Report on Form 10-K is filed with the Securities and Exchange Commission (SEC). The COVID-19 outbreak in the United States and the rest of the world has caused disruptions to the Company’s business, which may delay results of the Company’s clinical trials and adversely impact the Company’s business. The Company cannot predict how legal and regulatory responses to concerns about COVID-19 or other major public health issues will impact the Company’s business, nor can it predict potential adverse impacts related to the availability of capital to fund the Company’s operations. Additionally, the Company’s workforce and outside consultants may also be affected, which could result in an adverse impact on the Company’s ability to conduct business. Any of these factors, alone or in combination with others, could harm the Company’s business, results of operations, financial condition or liquidity. However, the magnitude, timing, and duration of any such potential financial impacts cannot be reasonably estimated at this time. Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) and the rules and regulations of the SEC. Any reference in these notes to applicable guidance is meant to refer to GAAP as found in the Accounting Standards Codification (ASC) and Accounting Standards Updates (ASU) promulgated by the Financial Accounting Standards Board (FASB). Principles of Consolidation In January 2019, the Company created a wholly-owned subsidiary in Australia with the Company serving as the sole shareholder through the subscription of shares. The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary. All intercompany transactions and balances have been eliminated in consolidation. F-7 Foreign Currency Translation The Company’s wholly-owned subsidiary in Australia uses its local currency as its functional currency. Assets and liabilities are translated into U.S. dollars at quarter-end exchange rates and revenues and expenses are translated at average exchange rates during the year-to-date periods. Foreign currency translation adjustments for the reported periods are included in accumulated other comprehensive loss in the Company’s consolidated statements of comprehensive loss, and the cumulative effect is included in the stockholders’ equity section of the Company’s consolidated balance sheets. Realized and unrealized gains and losses denominated in foreign currencies are recorded in operating expenses in the Company’s consolidated statements of operations. For the years ended December 31, 2020 and 2019, net realized and unrealized gains totaled $0.3 million and $15,000, respectively. Recent Accounting Pronouncements In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) , which amends the FASB ASC 840 and creates Topic 842, Leases. The new topic supersedes Topic 840, Leases, and increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and requires disclosures of key information about leasing arrangements. For companies that are not emerging growth companies (EGCs), ASU 2016-02 is effective for fiscal years beginning after December 15, 2018. For EGCs, the ASU was to be effective for fiscal years beginning after December 15, 2019. However, 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 (ASU 2019-10), which included a one-year deferral of the effective date of ASU 2016-02 for certain entities. As a result, the ASU is now effective for EGCs for fiscal years beginning after December 15, 2020, and interim periods within fiscal years beginning after December 15, 2021. The Company expects to adopt the new standard in the fourth quarter of 2021 using the modified retrospective method, under which the Company will apply Topic 842 to existing and new leases as of January 1, 2021, but prior periods will not be restated and will continue to be reported under Topic 840 guidance in effect during those periods. The Company anticipates that the adoption will not have a material impact on its consolidated statements of operations and consolidated comprehensive loss or its consolidated statements of cash flows but expects to recognize right-of-use assets and liabilities for lease obligations associated with its operating leases. In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments , which will require a reporting entity to use a new forward-looking impairment model for most financial assets that generally will result in the earlier recognition of allowances for losses. The ASU, along with related amendments, revised the measurement of credit losses for financial assets measured at amortized cost from an incurred loss to an expected loss methodology. The ASU affected receivables, debt securities, net investment in leases, and most other financial assets that represent a right to receive cash. The standard and other related subsequently issued ASUs will be effective for the Company for annual periods beginning after December 15, 2022, with early adoption permitted beginning in 2019. The Company is currently evaluating the impact that the adoption of the standard and other related subsequently issued ASUs will have on its consolidated financial statements and accompanying footnotes . In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes . The amendments in this ASU simplify the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. The amendments in this ASU are effective for the Company on January 1, 2021. The Company is currently evaluating the impact that the adoption of ASU 2019-12 will have on its consolidated financial statements and accompanying footnotes. Adopted Accounting Pronouncements In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820) – Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement , which is designed to improve the effectiveness of disclosures by removing, modifying and adding disclosures related to fair value measurements. ASU 2018-13 was effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption was permitted. The Company adopted this ASU on January 1, 2020. The adoption of this standard did not have a material impact on the Company’s consolidated financial statements. F-8 2. Summary of Significant Accounting Policies Use of Estimates The preparation of the Company’s consolidated financial statements requires the Company to make estimates and assumptions that impact the reported amounts of assets, liabilities and expenses and the disclosure of contingent assets and liabilities in the consolidated financial statements and accompanying notes. Significant estimates in the Company’s consolidated financial statements relate to clinical trial accruals and the valuation of equity awards. Management evaluates its estimates on an ongoing basis. Although estimates are based on the Company’s historical experience, knowledge of current events, and actions it may undertake in the future, actual results may ultimately materially differ from these estimates and assumptions. Concentration of Credit Risk and Off-Balance Sheet Risk Financial instruments which potentially subject the Company to significant concentration of credit risk consist of cash and cash equivalents and short-term investments. The Company maintains deposits in federally insured financial institutions in excess of federally insured limits. The Company has not experienced any losses in such accounts, and management believes that the Company is not exposed to significant credit risk due to the financial position of the depository institutions in which those deposits are held. The Company’s investment policy includes guidelines for the quality of the related institutions and financial instruments and defines allowable investments that the Company may invest in, which the Company believes minimizes the exposure to concentration of credit risk. Comprehensive Loss The Company is required to report all components of comprehensive loss, including net loss, in the consolidated financial statements in the period in which they are recognized. Comprehensive loss is defined as the change in equity during a period from transactions and other events and circumstances from non-owner sources, including unrealized gains and losses on investments and foreign currency gains and losses. Other comprehensive (loss) income, net includes unrealized losses or gains on short-term investments as well as foreign currency translation losses or gains. Cash and Cash Equivalents Cash and cash equivalents include cash in readily available checking and savings accounts, and money market funds. The Company considers all highly liquid investments with an original maturity of three months or less from the date of purchase to be cash equivalents. Short-Term Investments Available-for-sale securities are carried at fair value, with the unrealized gains and losses reported in comprehensive loss . The amortized cost of available-for-sale debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization and accretion are included in interest income. Realized gains and losses and declines in value judged to be other-than-temporary, if any, on available-for-sale securities are included in other income or expense. The cost of securities sold is based on the specific identification method. Interest and dividends on securities classified as available-for-sale are included in interest income. Prepaid Expenses and Other Current Assets Prepaid expenses and other current assets primarily represent amounts related to director and officer insurance, preclinical research and clinical trial agreements, equity issuance costs and an estimated tax refund for the year ended December 31, 2020 from the Australian Tax Office for eligible research and development expenditures. Property and Equipment Property and equipment is stated at cost and depreciated using the straight-line method over the estimated useful lives of the assets (generally three to five years). Impairment of Long-Lived Assets Long-lived assets consist primarily of property and equipment. An impairment loss is recorded if and when events and circumstances indicate that assets might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amount of those assets. While the Company’s current and historical operating losses and negative cash flows are indicators of impairment, management believes that future cash flows to be received support the carrying value of its long-lived assets and, accordingly, has not recognized any impairment losses since inception. F-9 Accrued Research and Development Expense The Company is required to estimate its expenses resulting from its obligations under contracts with vendors, consultants and contract research organizations, in connection with conducting research and development activities. The financial terms of these contracts are subject to negotiations, which vary from contract to contract and may result in payment flows that do not match the periods over which materials or services are provided under such contracts. The Company reflects research and development expenses in its consolidated financial statements by matching those expenses with the period in which services and efforts are expended. The Company accounts for these expenses according to the progress of the preclinical or clinical study as measured by the timing of various aspects of the study or related activities. The Company determines accrual estimates through review of the underlying contracts along with preparation of financial models taking into account discussions with research and other key personnel as to the progress of studies, or other services being conducted. During the course of a study, the Company adjusts its rate of expense recognition if actual results differ from its estimates. The Company classifies its estimates for accrued research and development expenses as accrued expenses on the accompanying consolidated balance sheet. Australian Research and Development Tax Incentive The Company is eligible under the Australian Research and Development Tax Incentive Program, or the Tax Incentive, to obtain a cash refund from the Australian Taxation Office for eligible research and development expenditures. To be eligible, the Company must have revenue of less than AUD $20.0 million during the reimbursable period and cannot be controlled by income tax exempt entities. The Tax Incentive is recognized as a reduction to research and development expense when there is reasonable assurance that the Tax Incentive will be received, the relevant expenditure has been incurred, and the amount can be reliably measured. The Company classifies its estimate for the Tax Incentive as prepaid expenses and other current assets on the accompanying consolidated balance sheet. Research and Development Research and development expenses include salaries and related overhead expenses, non-cash stock-based compensation expense, external research and development expenses incurred under arrangements with third parties, costs of services performed by consultants and contract research organizations, and regulatory costs including those related to preparing and filing INDs with the FDA. Research and development costs are expensed as incurred. Patent Costs The Company expenses all costs as incurred in connection with patent applications (including direct application fees, and the legal and consulting expenses related to making such applications) and such costs are included in general and administrative expenses in the consolidated statement of operations. Stock-based Compensation The Company measures employee and nonemployee stock-based awards, including stock options and purchase rights, at grant-date fair value and records compensation expense on a straight-line basis over the vesting period of the award. The Company uses the Black-Scholes option pricing model to value its stock option awards. Estimating the fair value of stock option awards requires management to apply judgment and make estimates of certain assumptions, including the volatility of the Company’s common stock, the expected term of the Company’s stock options, the expected dividend yield and the fair value of the Company’s common stock on the measurement date. As a result, if factors change and management uses different assumptions, stock-based compensation expense could be materially different for future awards. Income Taxes The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the consolidated financial statements. Under this method, deferred tax assets and liabilities are determined on the basis of the differences between the consolidated financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. The Company recognizes deferred tax assets to the extent that the Company believes these assets are more likely than not to be realized. In making such a determination, management 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. If management determines that the Company would be able to realize its deferred tax assets in the future in excess of their net recorded amount, management would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. F-10 The Company records uncertain tax positions on the basis of a two-step process whereby (1) management determines whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more- likely-than-not recognition threshold, management recognizes the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority. The Company recognizes interest and penalties related to unrecognized tax benefits within income tax expense. Any accrued interest and penalties are included within the related tax liability . Net Loss per Share Basic net loss per share is calculated by dividing the net loss by the weighted-average number of common shares outstanding for the period. Diluted net loss per share is computed by dividing the net loss by the weighted average number of common shares and common share equivalents outstanding for the period. Common stock equivalents are only included when their effect is dilutive. The Company’s potentially dilutive securities include outstanding options under the Company’s equity incentive plan and outstanding warrants to purchase common stock, each of which have been excluded from the computation of diluted net loss per share as they would be anti-dilutive to the net loss per share. For all periods presented, there is no difference in the number of shares used to calculate basic and diluted shares outstanding due to the Company’s net loss position. Potentially dilutive securities not included in the calculation of diluted net loss per share attributable to common stockholders because to do so would be anti-dilutive are as follows (in common stock equivalent shares): Year Ended December 31, Year Ended December 31, 2020 2019 Common stock options 2,463,317 1,821,093 Common stock warrants 80,428 80,428 Total 2,543,745 1,901,521 3. Fair Value of Financial Instruments The accounting guidance defines fair value, establishes a consistent framework for measuring fair value and expands disclosure for each major asset and liability category measured at fair value on either a recurring or nonrecurring basis. Fair value is defined as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the accounting guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: Level 1 —Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Level 2 —Quoted prices for similar assets and liabilities in active markets, quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability. Level 3 —Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e. supported by little or no market activity). Financial assets measured at fair value on a recurring basis consist of the Company’s cash equivalents and short-term investments. Cash equivalents consisted of money market funds and short-term investments consisted of U.S. treasury securities, agency securities and certificates of deposit . The Company obtains pricing information from its investment manager and generally determines the fair value of investment securities using standard observable inputs, including reported trades, broker/dealer quotes, and bid and/or offers. F-11 The following table s summarize the Company’s assets that require fair value measurements on a recurring basis and their respective input levels based on the fair value hierarchy (in thousands) : Fair Value Measurements Using Quoted Prices in Significant Significant Active Markets Other Unobservable December 31, for Identical Observable Inputs 2020 Assets (Level 1) Inputs (Level 2) (Level 3) Short-term investments: U.S. treasury securities $ 56,220 $ 56,220 $ - $ - Certificates of deposit 1,961 1,961 - - Total $ 58,181 $ 58,181 $ - $ - Fair Value Measurements Using Quoted Prices in Significant Significant Active Markets Other Unobservable December 31, for Identical Observable Inputs 2019 Assets (Level 1) Inputs (Level 2) (Level 3) Short-term investments: U.S. treasury securities $ 28,549 $ 28,549 $ - $ - Agency securities 5,994 - 5,994 - Certificates of deposit 5,381 5,381 - - Total $ 39,924 $ 33,930 $ 5,994 $ - U.S. treasury securities and certificates of deposit are valued using Level 1 inputs. Level 1 securities are valued at unadjusted quoted prices in active markets that are observable at the measurement date for identical, unrestricted assets or liabilities. Fair values determined by Level 2 inputs, which utilize data points that are observable such as quoted prices, interest rates and yield curves, require the exercise of judgment and use of estimates, that if changed, could significantly affect the Company’s financial position and results of operations. Investments in agency securities are valued using Level 2 inputs. Level 2 securities are initially valued at the transaction price and subsequently valued and reported utilizing inputs other than quoted prices that are observable either directly or indirectly, such as quotes from third-party pricing vendors. The carrying amounts of the Company’s financial instruments, including cash, prepaid and other current assets, accounts payable, and accrued liabilities, approximate fair value due to their short maturities. At December 31, 2020 and 2019, the carrying amount of the Company’s notes payable of $9.9 million and $9.7 million, respectively, approximated their fair value as the terms of the notes are consistent with the market terms of transactions with similar profiles (Level 2 inputs). None of the Company’s non-financial assets or liabilities are recorded at fair value on a non-recurring basis. At December 31, 2020 and 2019, the Company had investments in money market funds of $17.4 million and $10.3 million, respectively, that were measured at fair value using the net asset value per share (or its equivalent) that have not been classified in the fair value hierarchy. The funds invest primarily in U.S. government securities. The Company did not hold any Level 1, 2 or 3 financial liabilities that are recorded at fair value on a recurring basis as of December 31, 2020 or 2019. F-12 4. Short-term Investments The following table summarizes the Company’s short-term investments (in thousands): Maturity Amortized Unrealized Unrealized Estimated (in years) Cost Gains Losses Fair Value December 31, 2020 U.S. treasury securities 1 or less $ 56,218 $ 6 $ (4 ) $ 56,220 Certificates of deposit 1 or less 1,955 6 - 1,961 Total $ 58,173 $ 12 $ (4 ) $ 58,181 December 31, 2019 U.S. treasury securities 1 or less $ 23,513 $ 6 $ (4 ) $ 23,515 U.S. treasury securities >1 and <5 5,035 - (1 ) 5,034 Agency securities 1 or less 5,976 19 (1 ) 5,994 Certificates of deposit 1 or less 4,131 22 - 4,153 Certificates of deposit >1 and <5 1,220 8 - 1,228 Total $ 39,875 $ 55 $ (6 ) $ 39,924 All of the Company’s available-for-sale securities are available to the Company for use in its current operations. As a result, the Company categorizes all of these securities as current assets even though the stated maturity of some individual securities may be one year or more beyond the balance sheet date. All of the Company’s securities have a maturity within two years of the balance sheet date. There were no impairments considered other-than-temporary during the year ended December 31, 2020, as it is management’s intention and ability to hold the securities until a recovery of the cost basis or recovery of fair value. Unrealized gains and losses are included in accumulated other comprehensive (loss) income. 5. Property and Equipment Property and equipment consisted of the following (in thousands): December 31, December 31, 2020 2019 Furniture & fixtures $ 60 $ 60 Machinery & lab equipment 211 24 Computer equipment 42 38 Less accumulated depreciation and amortization (74 ) (29 ) Property and equipment, net $ 239 $ 93 Depreciation expense related to property and equipment was approximately $45,000 and $23,000 for the years ended December 31, 2020 and 2019, respectively. No material gains or losses on the disposal of property and equipment have been recorded for the years ended December 31, 2020 or 2019. 6. Accrued Expenses Accrued expenses consisted of the following (in thousands): December 31, December 31, 2020 2019 Accrued payroll and other employee benefits $ 1,870 $ 1,215 Clinical studies 493 442 Other accruals 307 267 Preclinical studies 72 15 Accrued interest 71 71 Total accrued expenses $ 2,813 $ 2,010 F-13 7 . Collaboration and License Agreement In May 2017, the Company entered into a collaboration and license agreement (which was amended in September 2018, April 2019 and December 2019), clinical supply agreement, investor rights agreement, and common stock purchase agreement (collectively License Agreements) with Biocon SA (subsequently assigned to Biocon Limited, or together, Biocon). Pursuant to the License Agreements, Biocon granted the Company an exclusive license to develop, make, have made, use, sell, have sold, offer for sale, import and otherwise exploit itolizumab and any pharmaceutical composition or preparation containing or comprising itolizumab that uses Biocon technology or Biocon know-how (collectively a Biocon Product) in the United States, Canada, Australia and New Zealand (collectively Company Territory). However, unless the Company achieves certain regulatory and development milestones within a specific time period, the licensed rights, other than development rights, are limited to the fields of orphan indications and the treatment of conditions related to asthma and lupus. The Company also has the right to sublicense through multiple tiers to third parties, provided such sublicenses comply with the terms of the License Agreements and the Company provides Biocon a copy of each sublicense agreement within 30 days of execution. If the Company grants a third party a sublicense of its rights to develop and commercialize Biocon Products in Australia or New Zealand, the Company will be required to pay Biocon a high double-digit percentage of any upfront payment the Company receives from such sublicensee for such sublicense, as well as a high double-digit percentage of any additional payments the Company receives from such sublicensee for such sublicense, including but not limited to royalty payments on net sales of Biocon Products by such sublicensee. Under the License Agreements, the Company granted back to Biocon a license to use its technology and know-how related to itolizumab and Biocon Products in certain countries outside of the Equillium Territory. Pursuant to the License Agreements, Biocon agreed to be the Company’s exclusive supplier of itolizumab clinical drug product. Biocon will provide clinical drug product at no cost for up to three concurrent orphan indications until the Company’s first U.S. regulatory approval and all other clinical drug product at Biocon’s cost. In consideration of the rights granted to the Company by Biocon, the Company issued Biocon a total of 2,316,134 shares of its common stock. In addition, the Company is obligated to pay Biocon up to an aggregate of $30 million in regulatory milestone payments upon the achievement of certain regulatory approvals and up to an aggregate of $565 million in sales milestone payments upon the achievement of first commercial sale of product and specified levels of product sales. The Company is also required to pay royalties on tiers of aggregate annual net sales of Biocon Products by us, our affiliates and our sublicensees in the United States and Canada at percentages from the mid-single digits to sub-teen double-digits and on tiers of aggregate annual net sales of Biocon Products by us and our affiliates (but not our sublicensees) in Australia and New Zealand, in each case, subject to adjustments in certain circumstances. Biocon is also required to pay the Company royalties at comparable percentages for sales of itolizumab (EQ001) outside of the Company Territory if the approvals in such geographies included or referenced the Company’s data including data from certain of the Company’s clinical trials, subject to adjustments in certain circumstances. Under the License Agreements, net sales are calculated on a country-by-country basis and are subject to adjustments, including whether the Biocon Product is sold in the form of a combination product. As of December 31, 2020, the Company has not made or received payments in connection with the milestones or royalties within the agreement. 8. Notes Payable On September 30, 2019 (the Effective Date), the Company entered into a Loan and Security Agreement (the Loan Agreement) with two lenders (the Lenders) whereby the Company can borrow up to $20.0 million in a series of term loans. Upon entering into the Loan Agreement, the Company borrowed $10.0 million from the Lenders (Term A Loan). Under the terms of the Loan Agreement, the Company may, at its sole discretion, borrow from the Lenders (i) up to an additional $5.0 million (Term B Loan) upon the Company’s achievement of positive topline data in either the Company’s (a) Phase 1b aGVHD trial of itolizumab (EQ001) or (b) Phase 1b asthma trial of itolizumab (EQ001), supporting a formal decision to advance into Phase 2 development, and as confirmed by the Board of Directors (the Board) of the Company (the Term B Milestone) and (ii) up to an additional $5.0 million (Term C Loan and together with Term A Loan and Term B Loan, the Term Loans) upon the Company’s achievement of positive topline data in both the Company’s Phase 1b aGVHD trial of itolizumab (EQ001) and the Company’s Phase 1b asthma trial of itolizumab (EQ001), supporting a formal decision to advance into Phase 2 development, and as confirmed by the Board (the Term C Milestone). The Company may draw the Term B Loan during the period commencing on the date of the occurrence of the Term B Milestone and ending on the earliest of (i) December 31, 2020, (ii) 60 days after achieving the Term B Milestone, and (iii) the occurrence of an event of default and may draw the Term C Loan during the period commencing on the date of the occurrence of the Term C Milestone and ending on the earliest of (i) December 31, 2020, (ii) 60 days after achieving the Term C Milestone, and (iii) the occurrence of an event of default. As of December 31, 2020, the Company did not achieve the Term B or Term C Milestone and is not eligible to receive the additional funding up to $10 million under the Loan Agreement. F-14 All of the Term Loans mature on June 1, 2024 (the Maturity Date) and require interest-only payments through June 30, 2021, followed by 36 equal monthly payments of principal and interest; provided that if the Company draws the Term B Loan, the Term Loans will require interest-only payments through December 31, 2021, followed by 30 equal monthly payments of principal and interest. The Term Loans will bear interest at a floating per annum rate equal to the greater of (i) 8.25 % and (ii) the sum of (a) the prime rate reported in The Wall Street Journal on the last business day of the month that immediately precedes the month in which the interest will accrue, plus (b) 3.00 %. On December 18, 2020, the Company entered into the First Amendment to the Loan Agreement (the Amendment) with the Lenders whereby if the Company achieves the Term B Milestone on or prior to June 30, 2021, the interest-only payments will be automatically extended to January 1, 2022. The Company has not yet achieved the Term B Milestone subsequent to December 31, 2020 and through the date of the filing of this Annual Report on Form 10-K. The Company will be required to make a final payment of 4.50% of the original principal amount of the Term Loans drawn payable on the earlier of (i) the Maturity Date, (ii) the acceleration of any Term Loans, or (iii) the prepayment of the Term Loans (the Final Payment). The Company may prepay all, but not less than all, of the Term Loans upon 30 days’ advance written notice to the lender, provided that the Company will be obligated to pay a prepayment fee equal to (i) 3.00% of the principal amount of the applicable Term Loan prepaid on or before the first anniversary of the applicable funding date, (ii) 2.00% of the principal amount of the applicable Term Loan prepaid between the first and second anniversary of the applicable funding date, and (iii) 1.00% of the principal amount of the applicable Term Loan prepaid thereafter, and prior to the Maturity Date (each, a Prepayment Fee). In connection with entering into the Loan Agreement, the Company issued to the Lenders warrants exercisable for 80,428 shares of the Company’s common stock (the Warrants). The Warrants are exercisable in whole or in part, immediately, and have a per share exercise price of $3.73, which is the closing price of the Company’s common stock reported on the Nasdaq Global Market on the day prior to the Effective Date. The Warrants will terminate on the earlier of September 30, 2029 or the closing of certain merger or consolidation transactions. If the Company borrows under Term B Loan and/or Term C Loan, upon the funding of Term B Loan and/or Term C Loan, as applicable, the Company will issue to the Lenders additional warrants to purchase shares of the Company’s common stock equal to 3.00% of each Term Loan amount divided by the lower of (i) the ten day average closing price of the Company’s common stock reported on the Nasdaq Global Market prior to funding or (ii) the closing price of the Company’s common stock reported on the Nasdaq Global Market on the day prior to funding. Such lower amount of (i) and (ii) above shall also be the exercise price per share for such warrants. The terms of such warrants would be substantially the same as those contained in the Warrants. The Company recorded the Warrants as a debt discount, which is classified as a contra-liability against long-term notes payable on the consolidated balance sheet and is amortizing the balance over the life of the underlying debt. The offset to the contra-liability is recorded in additional paid in capital in the Company’s consolidated balance sheet as the Warrants were determined to be equity classified. The Company determined the fair value of the Warrants at the date of issuance was $0.3 million using the Black-Scholes option pricing model based on significant unobservable inputs (Level 3) with an expected term of 10 years, volatility of 92.78%, risk free rate of 1.68% and expected dividend of 0%. The costs incurred to issue the Term Loans of $0.1 million were deferred and are included in the discount to the carrying value of the Term Loans in the accompanying consolidated balance sheet. The deferred costs and the Final Payment fee are amortized to interest expense over the expected term of the Term Loans using the effective interest method with an effective interest rate of 10.97%. The aggregate carrying amounts of the Term Loans are comprised of the following (in thousands): December 31, December 31, 2020 2019 Principal $ 10,000 $ 10,000 Add: accreted liability for final payment fee 176 35 Less: unamortized discount (235 ) (354 ) Total $ 9,941 $ 9,681 Upon the occurrence of certain events, including but not limited to the Company’s failure to satisfy its payment obligations under the Loan Agreement, the breach of certain of its other covenants under the Loan Agreement, or the occurrence of a material adverse change, cross defaults to other indebtedness or material agreements, judgment defaults and defaults related to failure to maintain governmental approvals failure of which to maintain could result in a material adverse effect, the Company’s lenders will have the right, among other remedies, to declare all principal and interest immediately due and payable, to exercise secured party remedies, to receive the Final Payment and, if the payment of principal and interest is due prior to the Maturity Date, to receive the applicable Prepayment Fee. At December 31, 2020, the Company was in compliance with the covenants contained in the Loan Agreement. F-15 Future maturities of the Term Loans, including the Final Payment fee, as of December 31, 2020 were as follows (in thousands): December 31, 2020 Year ending December 31, 2021 $ 1,667 Year ending December 31, 2022 3,333 Year ending December 31, 2023 3,333 Year ending December 31, 2024 2,117 10,450 Unaccreted balance for Final Payment fee on Term Loans (274 ) Unamortized discounts (235 ) 9,941 Less current portion (1,666 ) Noncurrent portion $ 8,275 9 . Stockholders’ Equity As of December 31, 2020, the Company’s authorized capital stock consisted of 200,000,000 shares of common stock, par value $0.0001 per share, and 10,000,000 shares of preferred stock, par value $0.0001 per share. The Company had 24,753,102 and 17,425,654 shares of common stock outstanding as of December 31, 2020 and 2019, respectively. Follow-On Public Offering In August 2020, the Company completed an underwritten public offering of 5,461,169 shares of common stock at $7.00 per share, which included 461,169 shares sold pursuant to the exercise of the underwriters’ option to purchase additional shares. The Company received gross proceeds from this offering totaling $38.2 million. The proceeds, net of underwriting discounts and related issuance costs, were $35.7 million. At-the-Market Offering Program In November 2019, the Company entered into an Open Market Sales Agreement SM with Jefferies LLC (Jefferies) under which the Company could offer and sell shares of its common stock from time to time, through an “at-the-market”, or ATM, equity offering program under which Jefferies acted as sales agent (2019 ATM Facility). The Company set certain parameters for the sale of shares, which included but were not limited to the number of shares to be issued, the time period during which sales are requested to be made, and any minimum price below which sales may not be made. Jefferies was entitled to compensation for its services at a commission rate of 3.0% of the gross sales price per share of common stock sold plus reimbursement of certain expenses. The maximum aggregate offering price of common stock that could be sold under the 2019 ATM Facility was $8.45 million. In December 2019, the Company sold an aggregate of 18,250 shares of its common stock under the 2019 ATM Facility resulting in net negative proceeds of $0.2 million, after deducting the facility’s costs. During the year ended December 31, 2020, the Company sold an aggregate 925,489 shares of its common stock and received gross proceeds of $8.4 million under the 2019 ATM Facility. The Company paid commissions on the gross proceeds in the aggregate amount of approximately $0.3 million, during the year ended December 31, 2020, resulting in net proceeds of $8.1 million. As of December 31, 2020, the 2019 ATM Facility was fully utilized. On July 14, 2020, the Company entered into a new ATM equity offering program (2020 ATM Facility) with Jefferies under which the Company may offer and sell shares of the Company’s common stock having an aggregate price of up to $150 million, from time to time, through Jefferies acting as our sales agent. For the year ended December 31, 2020, the Company sold an aggregate of 788,685 shares of common stock under the 2020 ATM Facility and received gross proceeds of $10.4 million. The Company paid cash commissions on the gross proceeds, plus reimbursement expenses to Jefferies and other issuance costs in the aggregate amount of approximately $0.4 million, resulting in net proceeds of $10.0 million. Since December 31, 2020 and through the date of the filing of this Annual Report on Form 10-K, there have been no additional sales of the Company’s stock under the 2020 ATM Facility. Purchase Agreement In March 2020, the Company entered into a purchase agreement (Purchase Agreement), with Lincoln Park Capital Fund, LLC (Lincoln Park), which provides that, upon the terms and subject to the conditions and limitations set forth therein, the Company F-16 may sell to Lincoln Park up to $ 15.0 million of shares of its common stock from time to time over the 36-month term of the Purchase Agreement. Upon execution of the Purchase Agreement, the Company issued 65,374 shares of its common stock to Lincoln Park as commitment shares in accordance with the closing conditions contained within the Purchase Agreement. The commitment shares were valued using the closing price of the Company’s common stock on the effective date of the Purchase Agreement resulting in a fair market value of approximately $ 0.2 million. The fair market value of the commitment shares as well as other issuance costs associated with the Purchase Agreement totaled $ 0.4 million. These issuance costs are classified as prepaid expenses and other current assets in the accompanying consolidated balance sheet. As shares of common stock are sold to Lincoln Park in accordance with the Purchase Agreement, the issuance costs, including the fair value of the commitment shares, will be reclassified to additional paid-in capital on the Company’s consolidated balance sheet . There have been no sales of the Company’s stock under this Purchase Agreement as of December 3 1 , 2020 and through the date of the filing of this Annual Report on Form 10- K . 2018 Equity Incentive Plan In October 2018, the Company adopted the 2018 Equity Incentive Plan (the 2018 Plan) which replaced the Company’s legacy 2017 Equity Incentive Plan (the 2017 Plan). The 2018 Plan provides for the grant of incentive stock options, non-statutory stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards, performance stock awards, performance cash awards and other forms of stock awards. As of December 31, 2020, the 2018 Plan had a maximum of 1,039,531 total shares available for issuance. The number of shares of common stock reserved for issuance under the 2018 Plan will automatically increase on January 1 of each calendar year through January 1, 2028, in an amount equal to 5.0% of the total number of shares of the Company’s capital stock outstanding on the last day of the calendar month before the date of each automatic increase, or a lesser number of shares determined by the Board. Options granted under the 2018 Plan are exercisable at various dates as determined upon grant and will expire no more than ten years from their date of grant. The exercise price of each option shall be determined by the Board based on the estimated fair value of the Company’s stock on the date of the option grant. The exercise price shall not be less than 100% of the fair market value of the Company’s common stock at the time the option is granted. Most option grants generally vest 25% on the first anniversary of the original vesting commencement date, with the balance vesting monthly over the remaining three years. Repricing of Outstanding Options On April 22, 2020, the Board approved a repricing of outstanding options to purchase 1,475,093 shares of the Company’s common stock held by employees of the Company, including executive officers (but excluding any employees who serve on the Board) that had exercise prices in excess of the closing stock price on April 22, 2020 and were granted under the Company’s equity incentive plans. As a result of the repricing, the exercise price of such options was lowered to $2.45 per share, the closing price of the Company’s common stock on April 22, 2020. The vesting schedule and term of these options remained unchanged. The Board effectuated the repricing to realign the value of such options with their intended purpose, which is to retain and motivate the holders of such options to continue to work in the best interests of the Company and its stockholders. Prior to the repricing, many of the options had exercise prices well above the market prices of the Company’s common stock at that time, including prior to the market volatility that had generally been associated with the onset of the COVID-19 pandemic. The effect of the repricing generated a total incremental cost of approximately $0.4 million, of which approximately $0.2 million was recognized as stock-based compensation expense in the year ended December 31, 2020, with the remainder to be expensed over the remaining vesting periods. Stock Options F-17 The following summarizes stock option activity for the year ended December 31, 2020 : Outstanding Options Weighted- Average Exercise Price Per Share Weighted Average Remaining Contractual Term (in years) Aggregate Intrinsic Value (in thousands) (a) Balances as of December 31, 2019 1,821,093 $ 5.64 9.24 $ 17 Granted 852,368 $ 4.29 Exercised (3,000 ) $ 2.45 Forfeitures and cancellations (207,144 ) $ 2.45 Balances as of December 31, 2020 (b) 2,463,317 $ 3.71 7.98 $ 4,726 Options exercisable as of December 31, 2020 (b) 1,041,624 $ 3.52 6.91 $ 2,177 (a) Aggregate intrinsic value in this table was calculated as the positive difference, if any, between the closing price per share of the Company’s common stock on December 31, 2020 of $5.35 and the price of the underlying options. (b) The weighted-average exercise price per share of the options outstanding and exercisable as of December 31, 2020 includes the impact of the repricing of 1,475,093 options on April 22, 2020 at $2.45 per share. The aggregate intrinsic value of stock options exercised was $9,000 and $0 for the years ended December 31, 2020 and 2019, respectively. Cash received from stock options exercised was $7,000 and $69,000 for the years ended December 31, 2020 and 2019, respectively. The fair value of stock options that vested in the years ended December 31, 2020 and 2019 was $4.1 million and $1.4 million, respectively. T he weighted-average grant-date fair value of options granted was $3.11 and $4.65 for the years ended December 31, 2020 and 2019, respectively. As of December 31, 2020, unrecognized compensation expense related to unvested stock options was $6.6 million and is expected to be recognized over a weighted-average period of 2.3 years. 2018 Employee Stock Purchase Plan In October 2018, the Company adopted the 2018 Equity Stock Purchase Plan (ESPP) whereby eligible employees may elect to withhold up to 15% of their earnings to purchase shares of the Company’s common stock at a price per share equal to the lower of (i) 85% of the fair market value of a share of the Company’s common stock on the first date of an offering or (ii) 85% of the fair market value of a share of the Company’s common stock on the date of the purchase right (purchase right). Initially, 343,275 shares of the Company’s common stock were approved for issuance under the ESPP pursuant to purchase rights granted to the Company’s employees or to employees of any of the Company’s designated affiliates. The number of shares of the Company’s common stock reserved for issuance will automatically increase on January 1 of each calendar year through January 1, 2028, by the lesser of (1) 1.0% of the total number of shares of the Company’s common stock outstanding on the last day of the calendar month before the date of the automatic increase, and (2) 343,275 shares; provided that before the date of any such increase, the Board may determine that such increase will be less than the amount set forth in clauses (1) and (2). As of December 31, 2020, the Company had issued 78,764 shares of common stock under the ESPP, 65,443 of which were issued during the year ended December 31, 2020. The Company had 612,529 shares available for future issuance under the ESPP as of December 31, 2020. Liability for Early Exercise of Restricted Stock Options All stock option grants under the 2017 Plan provide for exercise of the stock option prior to vesting. Shares of common stock issued upon exercise of unvested options are subject to repurchase by the Company at the respective original exercise price until vested. Consideration received for the exercise of unvested stock options is recorded as a liability and reclassified into equity as the related award vests. As of December 31, 2020 and 2019, 153,690 and 265,232 unvested shares issued under early exercise provisions were subject to repurchase by the Company, respectively. The balance sheet reflects an unvested stock liability of $0.1 million and $0.2 million as of December 31, 2020 and 2019, respectively. The short-term portion of the unvested stock liability totals approximately $72,000 as of December 31, 2020, and is classified as accrued expenses on the accompanying consolidated balance sheet. The long-term portion of the unvested stock liability totals approximately $53,000 as of December 31, 2020, and is classified as other non-current liabilities on the accompanying consolidated balance sheet. F-18 Stock- b ased Compensation Expense On May 28, 2020, the Compensation Committee of the Board issued to its Executive Chairman, Chief Executive Officer and two non-management directors retention stock options to purchase an aggregate of 169,368 shares of the Company’s common stock. These stock option grants immediately vested at the date of grant. The non-cash stock-based compensation expense recognized in the year ended December 31, 2020 associated with these stock option grants totaled $0.4 million. At the time, the Executive Chairman and Chief Executive Officer voluntarily agreed to a 65% and an 85% reduction, respectively, in their base salaries otherwise payable for the remainder of 2020. The two non-management directors voluntarily agreed to forego 100% of their annual cash retainers otherwise payable to such directors for the remainder of 2020. Total non-cash stock-based compensation expense for all stock awards and purchase rights, net of forfeitures recognized as they occur, that was recognized in the consolidated statement of operations is as follows (in thousands): Year Ended December 31, Year Ended December 31, 2020 2019 Research and development $ 1,773 $ 1,207 General and administrative 2,044 1,045 Total $ 3,817 $ 2,252 The weighted-average assumptions used in the Black-Scholes option pricing model to determine the fair value of the employee and nonemployee stock option grants were as follows: Year Ended December 31, Year Ended December 31, 2020 2019 Risk-free interest rate 0.65% 2.23% Expected volatility 89.56% 93.58% Expected term (in years) 5.77 5.77 Expected dividend yield 0% 0% Risk-free interest rate. The risk-free rate assumption is based on the U.S. Treasury instruments, the terms of which were consistent with the expected term of the Company’s stock options. Expected volatility. Due to the Company’s limited operating history and lack of company-specific historical or implied volatility as a private company, the expected volatility assumption was determined by examining the historical volatilities of a group of industry peers whose share prices are publicly available. Expected term. The expected term of stock options represents the weighted-average period the stock options are expected to be outstanding. The Company uses the simplified method for estimating the expected term as provided by the SEC. The simplified method calculates the expected term as the average of the time-to-vesting and the contractual life of the options. Expected dividend yield. The expected dividend assumption is based on the Company’s history and expectation of dividend payouts. The Company has not paid and does not intend to pay dividends. Forfeitures . The Company reduces stock-based compensation expense for actual forfeitures during the period. Common Stock Reserved for Future Issuance Common stock reserved for future issuance consists of the following as of December 31, 2020 and 2019: December 31, December 31, 2020 2019 Stock options issued and outstanding 2,463,317 1,821,093 Warrants for common stock 80,428 80,428 Awards available under the 2018 Equity Incentive Plan 1,039,531 813,473 Employee stock purchase plan 612,529 503,716 Total 4,195,805 3,218,710 F-19 10. Commitments and Contingencies Leases and Other Commitments The Company leases certain office space in La Jolla and South San Francisco, California under non-cancelable operating leases. The leases for spaces in La Jolla and South San Francisco expire in February 2022. Rent expense was $0.2 million for both the years ended December 31, 2020 and 2019. The future minimum lease payments required under non-cancelable leases as of December 31, 2020, are summarized as follows (in thousands): Years Ending December 31, 2021 $ 153 2022 26 Total $ 179 The Company enters into service agreements with indemnification clauses in the ordinary course of business. Pursuant to such clauses, the Company indemnifies, defends, holds harmless, and agrees to reimburse the indemnified party for losses suffered or incurred by third party claims arising out of the indemnified party’s performance of service. The Company has not incurred costs to defend lawsuits pursuant to these indemnification clauses. Litigation As of December 31, 2020, there was no litigation against the Company . 11 . Income Taxes The components of loss before income tax provision (benefit) for the years ended December 31, 2020 and 2019 consisted of the following (in thousands): Year Ended December 31, Year Ended December 31, 2020 2019 U.S. (29,420 ) (23,167 ) Foreign (393 ) (2,433 ) $ (29,813 ) $ (25,600 ) The Company has not recorded a current or deferred tax expense or benefit for the years ended December 31, 2020 and 2019. The following is a reconciliation of the expected statutory federal income tax provision to our actual income tax provision for the years ended December 31, 2020 and 2019 (in thousands): Year Ended December 31, Year Ended December 31, 2020 2019 Income taxes at statutory rates $ (6,261 ) $ (5,376 ) State income tax, net of federal benefit - 1 Stock-based compensation 97 276 Permanent items 15 54 Federal research and orphan drug credits (445 ) (684 ) Foreign rate differential 367 (158 ) Change in federal valuation allowance 6,227 5,887 $ - $ - F-20 The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities as of December 31, 2020 and 2019 are as follows (in thousands): December 31, December 31, 2020 2019 Deferred tax assets: Net operating loss carryforward $ 12,338 $ 7,212 Credits 1,940 1,227 Intangibles 118 129 Equity compensation 888 188 Other 286 221 Total deferred tax assets 15,570 8,977 Valuation allowance (15,564 ) (8,976 ) Total deferred tax assets, net of allowance $ 6 $ 1 Deferred tax liabilities: Other (6 ) (1 ) Total deferred tax liabilities $ (6 ) $ (1 ) Net deferred taxes $ - $ - The Company has established a valuation allowance against its net deferred tax assets due to the uncertainty surrounding the realization of such assets. The Company periodically evaluates the recoverability of the deferred tax assets. At such time as it is determined that it is more likely than not that deferred assets are realizable, the valuation allowance will be reduced. The Company has recorded a full valuation allowance of $15.6 million as of December 31, 2020 as it does not believe it is more likely than not that certain deferred tax assets will be realized primarily due to the generation of pre-tax book losses in the current year, the lack of feasible tax-planning strategies, the limited existing taxable temporary differences, and the subjective nature of forecasting future taxable income into the future. The Company increased its valuation allowance by approximately $6.6 million during the year ended December 31, 2020. At December 31, 2020, the Company had federal and California tax loss carry forwards of approximately $53.9 million and $30.7 million, respectively. The federal net operating loss carryover includes $53.0 million of net operating losses generated subsequent to 2017. Federal net operating losses generated after December 31, 2017 carryover indefinitely and may generally be used to offset up to 80% of future taxable income. The federal net operating losses generated prior to 2018 as well as the state net operating loss carry forwards, begin to expire in 2037 unless previously utilized. The Company has $1.9 million of Australian net operating loss carryforwards as of December 31, 2020 that are carried forward indefinitely. F-21 At December 31, 2020 , the Company had federal and state tax credit carry forwards of approximately $ 1.4 million and $ 0.6 million , respectively, after reduction for uncertain tax positions. The Company has not performed a formal research and development credit study with respect to these credits. The federal credits will begin to expire in 2037 , if unused, and the state credits carry forward indefinitely. Pursuant to the Internal Revenue Code of 1986, as amended (IRC), specifically Section 382 and 383, the Company's ability to use net operating loss and research and development tax credit carry forwards (tax attribute carry forwards) to offset future taxable income is limited if the Company experiences a cumulative change in ownership of more than 50% within a three-year testing period. The Company has not completed an ownership change analysis pursuant to IRC Section 382. If ownership changes within the meaning of IRC Section 382 are identified as having occurred, the amount of remaining tax attribute carry forwards available to offset future taxable income and income tax expense in future years may be significantly restricted or eliminated. Further, our deferred tax assets associated with such tax attributes could be significantly reduced upon realization of an ownership change within the meaning of IRC Section 382. The following table summarizes the reconciliation of the unrecognized tax benefits activity during the years ended December 31, 2020 and 2019 (in thousands): Year Ended December 31, Year Ended December 31, 2020 2019 Unrecognized tax benefits – beginning $ 360 $ 89 Gross increases – tax positions in prior period 1,988 - Gross decreases – tax positions in prior period - - Gross increase – current-period tax positions 319 271 Gross decrease – current-period tax positions - - Settlements - - Lapse of statute of limitations - - Unrecognized tax benefits – ending $ 2,667 $ 360 The unrecognized tax benefit amounts are reflected in the determination of the Company’s deferred tax assets. If recognized, none of these amounts would affect the Company’s effective tax rate, since it would be offset by an equal corresponding adjustment in the deferred tax asset valuation allowance. The Company does not foresee material changes to its liability for uncertain tax benefits within the next twelve months. The Company's policy is to recognize interest and/or penalties related to income tax matters in income tax expense. The Company had no accrual for interest or penalties on the Company's consolidated balance sheet as of December 31, 2020 and has not recognized interest and/or penalties in the consolidated statement of operations for the year ended December 31, 2020. All tax years for both federal and state purposes remain open and subject to examination by tax jurisdictions. On March 27, 2020, the United States enacted the Coronavirus Aid, Relief and Economic Security Act (CARES Act). The CARES Act is an emergency economic stimulus package that includes spending and tax breaks to strengthen the United States economy and fund a nationwide effort to curtail the effect of COVID-19. While the CARES Act provides sweeping tax changes in response to the COVID-19 pandemic, some of the more significant provisions are the extension of the carryback period of certain losses to five years, and the suspension of the 80 percent limitation imposed by the Tax Cuts and Jobs Act of 2017 (TCJA) on utilization of net operating losses generated in 2018, 2019 and 2020 to offset taxable income generated in tax years prior to 2021. The CARES Act also increased the ability to deduct interest expense from 30 percent, as imposed by the TCJA, to 50 percent of modified taxable income. The CARES Act also provides a credit against employee wages, the opportunity to defer payment of a portion of federal payroll taxes to December 2021 and December 2022, and enhanced small business loans to assist businesses impacted by the pandemic. The Company’s tax provision and financial position was not materially impacted by the CARES Act. On December 27, 2020, the United States enacted the Consolidated Appropriations Act, which extended and modified many of the tax related provisions of the CARES Act. The Company does not anticipate a material impact of the Consolidated Appropriations Act on its tax provision or financial position. F-22 1 2 . Retirement Plan The Company sponsors an employee savings plan that qualifies as a deferred salary arrangement under Section 401(k) of the IRC. Participating employees may defer up to the Internal Revenue Service annual contribution limit. The Company did not made any contributions for the years ended December 31, 2020 or 2019. 13 . Selected Quarterly Financial Data (unaudited) The following table contains unaudited quarterly financial information for the years ended December 31, 2020 and 2019.

Subsequent Events On February 3, 2021, the Company entered into a securities purchase agreement (the Securities Purchase Agreement) with two institutional investors (the Purchasers), relating to the issuance and sale (the Offering) of an aggregate of 4,285,710 shares of common stock and warrants to purchase 1,285,713 shares of common stock (the Warrants) for aggregate gross proceeds to the Company from this Offering of approximately $30.0 million, excluding any proceeds the Company may receive upon exercise of the Warrants. No underwriter or placement agent participated in the Offering. The Warrants are exercisable immediately upon issuance at an initial exercise price of $14.00 per share and are exercisable on a cashless basis. The Warrants expire on the earlier of (i) the fifth anniversary of issuance or (ii) the 15 th calendar date following the date on which the Company closes upon an equity financing that results in not less than $25 million of gross proceeds to the Company at a price per share of common stock equal to or greater than $25.00, at which time, all remaining Warrants will automatically exercise on a cashless basis. The exercise price and the number of shares of common stock purchasable upon the exercise of the Warrants are subject to adjustment upon the occurrence of specific events, including stock dividends, stock splits, reclassifications and combinations of the Company’s common stock. Pursuant to the terms of the Securities Purchase Agreement, the Company agreed to appoint Dr. Yu (Katherine) Xu, Ph. D. to the Board as a nominee of the Purchasers. F-23
