SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q contains forward-looking statements that involve risks and uncertainties. All statements other than statements of historical facts contained in this Quarterly Report are forward-looking statements. In some cases, you can identify forward-looking statements by words such as “anticipate,” “believe,” “contemplate,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “plan,” “potential,” “predict,” “project,” “seek,” “should,” “target,” “will,” “would,” or the negative of these words or other comparable terminology. These forward-looking statements include, but are not limited to, statements about:

•our sales, marketing and distribution capabilities and strategy;

These forward-looking statements are subject to a number of risks, uncertainties and assumptions, including those described in “Risk Factors” and elsewhere in this Quarterly Report. Moreover, we operate in a very competitive and rapidly changing environment, and new risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties and assumptions, the forward-looking events and circumstances discussed in this Quarterly Report may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements.

ii

You should not rely upon forward-looking statements as predictions of future events. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee that the future results, levels of activity, performance or events and circumstances reflected in the forward-looking statements will be achieved or occur. We undertake no obligation to update publicly any forward-looking statements for any reason after the date of this Quarterly Report to conform these statements to new information, actual results or to changes in our expectations, except as required by law.

You should read this Quarterly Report and the documents that we have filed with the Securities and Exchange Commission (SEC), as exhibits to this Quarterly Report with the understanding that our actual future results, levels of activity, performance, and events and circumstances may be materially different from what we expect.

In addition, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based upon information available to us as of the date of this Quarterly Report, and while we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain and investors are cautioned not to unduly rely upon these statements.

1. Basis of Presentation

Iterum Therapeutics plc (the Company) was incorporated under the laws of the Republic of Ireland in June 2015 as a limited company and re-registered as a public limited company on March 20, 2018. The Company maintains its registered office at Block 2 Floor 3, Harcourt Centre, Harcourt Street, Dublin 2, Ireland. The Company commenced operations in November 2015. The Company licensed global rights to its novel anti-infective compound, sulopenem, from Pfizer Inc. (Pfizer). The Company is a clinical-stage pharmaceutical company dedicated to developing and commercializing sulopenem to be potentially the first and only oral and intravenous (IV) branded penem available globally.

Since inception, the Company has devoted substantially all of its efforts to research and development, recruiting management and technical staff and raising capital, and has financed its operations through the issuance of ordinary shares and convertible preferred shares, debt raised under financing arrangements with Silicon Valley Bank (SVB) including the Paycheck Protection Program loan (PPP loan), a sub-award from the Trustees of Boston University under the Combating Antibiotic Resistant Bacteria Biopharmaceutical Accelerator (CARB-X) program and the proceeds of a private placement and subsequent rights offering pursuant to which its wholly owned subsidiary, Iterum Therapeutics Bermuda Limited (Iterum Bermuda), issued and sold approximately $51.8 million aggregate principal amount of 6.500% Exchangeable Senior Subordinated Notes due 2025 (Exchangeable Notes) and $0.1 million aggregate principal amount of Limited Recourse Royalty-Linked Subordinated Notes (the RLNs and, together with the Exchangeable Notes, the Securities). The Company has not generated any product revenue. The Company is subject to risks and uncertainties common to early-stage companies in the pharmaceutical industry, including, but not limited to, the ability to secure additional capital to fund operations, failure to achieve regulatory approval, failure to successfully develop and commercialize its product candidates, development by competitors of new technological innovations, dependence on key personnel, protection of proprietary technology and compliance with government regulations. Product candidates currently under development will require additional research and development efforts, including regulatory approval prior to commercialization.

Even if the Company’s product development efforts are successful, it is uncertain when, if ever, the Company will realize significant revenue from product sales.

The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) and include the accounts of the Company and its subsidiaries.

On July 5, 2019, the Company filed a universal shelf registration statement on Form S-3 with the SEC, which was declared effective on July 16, 2019 (File No. 333-232569), and pursuant to which it registered for sale up to $150.0 million of any combination of its ordinary shares, preferred shares, debt securities, warrants and/or units from time to time and at prices and on terms that the Company may determine.

On January 21, 2020, the Company completed a private placement pursuant to which its wholly owned subsidiary, Iterum Bermuda, issued and sold approximately $51.6 million aggregate principal amount of Exchangeable Notes and $0.1 million aggregate principal amount of RLNs to a group of accredited investors (the Private Placement). The Securities were sold in units (the Units) in the Private Placement and Rights Offering with each Unit consisting of an Exchangeable Note in the original principal amount of $1,000 and 50 RLNs) In connection with the Private Placement, the Company agreed to undertake a rights offering of subscription rights to purchase additional Units (the Rights Offering). Under the Rights Offering, the Company and Iterum Bermuda, distributed to the Company’s eligible holders of ordinary shares and eligible warrant holders one non-transferable subscription right for each ordinary share owned (or deemed owned in the case of eligible warrant holders) as of the close of business on the record date, August 5, 2020. The subscription period for the Rights Offering expired on August 31, 2020 and right holders subscribed for 220 units. As a result, on September 8, 2020, Iterum Bermuda issued and sold approximately $0.2 million aggregate principal amount of Exchangeable Notes and $0.02 million aggregate principal amount of RLNs.  The Units were sold at a price of $1,000 per Unit. The Exchangeable Notes are exchangeable for the Company’s ordinary shares, cash or a combination of ordinary shares and cash, at an initial exchange rate of 1,000 shares per $1,000 of principal and interest on the Exchangeable Notes (equivalent to an initial exchange price of $1.00 per ordinary share), subject to specified limitations, which exchange rate was adjusted to 1,286.1845  shares per $1,000 of principal and interest on the Exchangeable Notes (equivalent to an exchange price of approximately $0.7775 per ordinary share) as of November 2, 2020 and is subject to further adjustment pursuant to the terms and conditions of the indenture governing the Exchangeable Notes. The RLNs entitle holders to payments based on a percentage of the Company’s net revenues from potential U.S. sales of specified sulopenem products, subject to the terms and conditions of the indenture governing the RLNs. Pursuant to the indenture governing the RLNs, the payments on the RLNs will be up to either 15% or 20% of net revenues from U.S. sales of such products, depending on the indication approved by the U.S. Food and Drug Administration (the FDA). The aggregate amount of payments on each RLN is capped at $160.00 (or 4,000 times the principal amount of such RLN). Iterum Bermuda received net proceeds from the sales of the Securities of approximately $45.0 million, after deducting placement agent fees and offering expenses.

In April 2020, the Company began deferring payment on its share of U.S. payroll taxes owed, as allowed by the Coronavirus Aid, Relief and Economic Security Act (CARES Act) through December 31, 2020. The Company is able to defer half of its share of U.S. payroll taxes owed until December 31, 2021, with the remaining half due on December 31, 2022.

On April 3, 2020, the U.S. Small Business Administration (SBA) launched a Paycheck Protection Program (the Program) established following the signing of the CARES Act on March 27, 2020. On April 30, 2020, the Company’s wholly owned subsidiary, Iterum Therapeutics US Limited, (the Borrower) entered into the PPP loan with SVB (the Lender) under the Program, pursuant to the Company receiving a loan of $0.7 million with a fixed 1% annual interest rate and a maturity of two years. Under the terms of the agreement, there shall be no payments due by the Company until the later of the date the SBA remits the forgiveness amount to the borrower or 10 months after the end of the six-month period beginning April 30, 2020 (the Deferral Period). Following the Deferral Period, equal monthly repayments of principal and interest will be due to fully amortize the principal amount outstanding on the PPP loan on the last day of the Deferral Period by the maturity date. Under the terms of the Program, the SBA will forgive the portion of loan proceeds used for U.S. payroll costs and other designated operating expenses for up to 24 weeks, provided at least 60% of the loan proceeds are used for U.S. payroll costs. The Company incurred qualifying payroll costs and other operating expenses in the 24 weeks following April 30, 2020, and has requested forgiveness for a portion of the PPP loan from the Lender. Any forgiveness of the PPP loan will be made in accordance with SBA requirements and subject to approval by SVB. No assurance is provided that the Company will obtain forgiveness in whole or in part.

On June 3, 2020, the Company entered into a Securities Purchase Agreement (June 3 SPA) with certain institutional investors (the June 3 Purchasers) pursuant to which the Company issued and sold, in a registered direct offering (June 3 Offering), an aggregate of 2,971,770 ordinary shares, $0.01 nominal value per share, at a purchase price per share of $1.6825, for aggregate gross proceeds to the Company of $5.0 million and net proceeds of $4.3 million after deducting fees payable to the placement agent and other offering expenses payable by the Company. We offered the ordinary shares in the June 3 Offering pursuant to our universal shelf registration statement on Form S-3.  Pursuant to the June 3 SPA, in a concurrent private placement, the Company issued and sold to the June 3 Purchasers warrants to purchase up to 1,485,885 ordinary shares. Upon closing, the warrants became exercisable immediately at an exercise price of $1.62 per ordinary share, subject to adjustment in certain circumstances, and will expire on December 5, 2025. The closing date of the June 3 Offering was June 5, 2020. Warrants to purchase 208,023 ordinary shares, amounting to 7% of the ordinary shares issued under the June 3 SPA, were issued to designees of the placement agent on the closing of the June 3 Offering Upon closing, the warrants issued to such designees were exercisable immediately at an exercise price of $2.1031 per ordinary share, and will expire on June 3, 2025.

On June 30, 2020, the Company entered into a securities purchase agreement (June 30 SPA) with certain institutional investors (the June 30 Purchasers) pursuant to which the Company issued and sold in a registered direct offering (June 30 Offering) an aggregate of 3,372,686 ordinary shares, $0.01 nominal value per share, at a purchase price per share of $1.4825, for aggregate gross proceeds to the Company of $5.0 million and net proceeds of $4.2 million after deducting fees payable to the placement agent and other offering expenses payable by the Company. We offered the ordinary shares in the June 30 Offering pursuant to our universal shelf registration statement on Form S-3.  Pursuant to the June 30 SPA, in a concurrent private placement, the Company issued and sold to the June 30 Purchasers warrants to purchase up to 1,686,343 ordinary shares. Upon closing, the warrants were exercisable immediately at an exercise price of $1.42 per ordinary share, subject to adjustment in certain circumstances, and will expire on January 2, 2026. The June 30 Offering closed on July 2, 2020. Warrants to purchase 236,088 ordinary shares, amounting to 7% of the ordinary shares issued under the June 30 SPA, were issued to designees of the placement agent on closing of the June 30 Offering. Upon closing, the warrants issued to such designees were exercisable immediately at an exercise price of $1.8531 per ordinary share, and will expire on June 30, 2025.

On October 27, 2020, the Company completed a registered public offering (the October Offering) in which it sold an aggregate of (i) 15,511,537 ordinary shares, $0.01 nominal value per share, (ii) pre-funded warrants exercisable for an aggregate of 11,411,539 ordinary shares and (iii) warrants exercisable for an aggregate of 20,192,307 ordinary shares. The pre-funded warrants were issued and sold to certain purchasers whose purchase of ordinary shares in the October Offering would have otherwise resulted in the purchaser, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or, at the election of the purchaser, 9.99%) of the Company’s outstanding ordinary shares immediately following the consummation of the October Offering, if the purchaser so chose in lieu of ordinary shares that would have otherwise resulted in such excess ownership. The ordinary shares and pre-funded warrants were each offered together with the warrants, but the ordinary shares and pre-funded warrants were issued separately from the warrants. The combined offering price was $0.65 per ordinary share and warrant and $0.64 per pre-funded warrant and warrant. The Company’s net proceeds from the October Offering, after deducting placement agent fees and other estimated offering expenses payable by the Company, were approximately $15.3 million. The warrants are exercisable upon issuance at a price of $0.65 per ordinary share, subject to adjustment in certain circumstances, and expire on October 27, 2025. The pre-funded warrants are exercisable upon issuance at a price of $0.01 per ordinary share, subject to adjustment in certain circumstances, and expire when exercised in full, subject to certain conditions. As of October 31, 2020, pre-funded warrants to purchase 6,284,615 ordinary shares had

5

(In thousands, except share and per share data)

been exercised for net proceeds of $0.06 million. In connection with the October Offering, the Company entered into a Securities Purchase Agreement (the Purchase Agreement) on October 22, 2020 with certain institutional investors. The Purchase Agreement contains customary representations and warranties of the Company, termination rights of the parties, and certain indemnification obligations of the Company and ongoing covenants of the Company, including a prohibition on issuance of ordinary shares or securities convertible or exchangeable into ordinary shares by the Company for a period of 45 days after the closing of the October Offering and a prohibition on the Company entering into variable rate transactions for a period of 12 months after the closing of the October Offering, subject to certain exceptions. Warrants to purchase 1,884,615 ordinary shares, which represents a number of ordinary shares equal to 7.0% of the aggregate number of ordinary shares and pre-funded warrants sold in the October Offering, were issued to designees of the placement agent on closing of the October Offering. Upon closing, the warrants issued to such designees became exercisable immediately at an exercise price of $0.8125 per ordinary share and will expire on October 22, 2025.

In accordance with Accounting Standards Update (ASU) 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (Subtopic 205-40), the Company has evaluated whether there are conditions and events, considered in aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern within one year of the date of issue of these quarterly condensed consolidated financial statements.

The Company has funded its operations to date primarily with proceeds from the sale of preferred shares and ordinary shares, warrants, debt raised under financing arrangements with SVB including the PPP loan, payments received under the CARB-X program and the proceeds of the Private Placement and Rights Offering. The Company has incurred operating losses since inception, including net losses of $40,820 and $79,489 for the nine months ended September 30, 2020 and 2019, respectively, and a net loss of $103,130 for the year ended December 31, 2019. The Company had an accumulated deficit of $275,743 as of September 30, 2020 and expects to continue to incur net losses for the foreseeable future. The Company’s future cash flows are dependent on key variables such as its ability to secure additional sources of funding in the form of public or private financing of debt or equity or collaboration agreements.

The Company may not be able to obtain financing on acceptable terms, or at all. The terms of any financing may adversely affect the holdings or the rights of the Company's shareholders. If the Company is unable to obtain funding, it could be forced to delay, reduce or eliminate some or all of its research and development programs or commercialization efforts, which could adversely affect its business prospects, or the Company may be unable to continue operations. Although management continues to pursue these plans, and the Company has successfully raised capital in the past, there is no assurance that the Company will be successful in obtaining sufficient funding on terms acceptable to the Company to fund continuing operations, if at all.

In addition, in parallel, the Company is evaluating its corporate, organizational, strategic, financial and financing alternatives, with the goal of maximizing value for its stakeholders while prudently managing its resources. These alternatives could potentially include the licensing, sale or divestiture of the Company’s assets or proprietary technologies, a sale of the Company, a merger or other business combination, another strategic transaction involving the Company, restructuring activities, winding down of operations, dissolving and liquidating assets or seeking protection under bankruptcy laws. The evaluation of corporate, organizational, strategic, financial and financing alternatives may not result in any particular action or any transaction being pursued, entered into or consummated, and there is no assurance as to the timing, sequence or outcome of any action or transaction or series of actions or transactions.  

Based on the Company’s operating losses since inception, the expectation of continued operating losses for the foreseeable future and the need to raise additional capital to finance its future operations, management have concluded there is substantial doubt about the Company’s ability to continue as a going concern within one year from the date this Quarterly Report on Form 10-Q is issued. The accompanying condensed consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. Accordingly, the condensed consolidated financial statements have been prepared on a basis that assumes the Company will continue as a going concern and which contemplates the realization of assets and satisfaction of liabilities and commitments in the ordinary course of business.

COVID-19 Global Pandemic

In December 2019, an outbreak of COVID-19 was reported in Wuhan, China. On March 11, 2020, the World Health Organization declared COVID-19 a global pandemic and on March 13, 2020, President Donald J. Trump declared the virus a national emergency. This highly contagious disease has spread to most of the countries in the world and throughout the United States, creating a serious impact on customers, workforces, and suppliers, disrupting economies and financial markets and leading to a world-wide economic downturn. It has caused a disruption of the normal operations of many businesses, including the temporary closure or scale-back of business operations and/or the imposition of either quarantine or remote work or meeting requirements for employees, either by government order or on a voluntary basis. The pandemic may impact the ability of the Company’s strategic partners to operate and fulfill their contractual obligations, and result in an increase in their costs and cause delays in performance. These effects, and the direct effect of the virus and any potential disruption on the Company’s operations, may negatively impact the Company’s ability to

6

ITERUM THERAPEUTICS PLC

Notes to Unaudited Condensed Consolidated Financial Statements

(In thousands, except share and per share data)

meet the Company’s strategic targets. The Company’s employees, in most cases, are working remotely due to safety concerns and using various technologies to perform their functions. Additionally, the disruption and volatility in the global and domestic capital markets may increase the cost of capital and limit the Company’s ability to access capital. Both the health and economic aspects of COVID-19 are highly fluid and the future course of each is uncertain. For these reasons and other reasons that may come to light if the coronavirus pandemic and associated protective or preventative measures expand, the Company may experience a material adverse effect on its business operations and financial condition; however, its ultimate impact is highly uncertain and subject to change.

The Company cannot foresee if and when the outbreak of COVID-19 will be effectively contained, nor can the Company predict the severity and duration of its impact. Management is actively monitoring the global situation on its financial condition, liquidity, operations, suppliers, industry, and workforce. Given the daily evolution of the COVID-19 outbreak and the global responses to curb its spread, the Company is not able to estimate the adverse effects of the COVID-19 outbreak on its results of operations, financial condition, or liquidity.

Interim Financial Information

The condensed consolidated balance sheet at December 31, 2019 was derived from audited financial statements, but does not include all disclosures required by GAAP. The accompanying unaudited condensed consolidated financial statements as of September 30, 2020 and for the three and nine months ended September 30, 2020 and 2019 have been prepared by the Company pursuant to the rules and regulations of the SEC for interim financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. These condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and the notes thereto for the year ended December 31, 2019, included in the Company’s Annual Report on Form 10-K filed with the SEC on March 12, 2020. In the opinion of management, all adjustments, consisting only of normal recurring adjustments necessary for a fair statement of the Company’s financial position as of September 30, 2020, and results of operations for the three and nine months ended September 30, 2020 and 2019, and cash flows for the nine months ended September 30, 2020 and 2019 have been made. The results of operations for the three and nine months ended September 30, 2020 are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2020.

2. Summary of Significant Accounting Policies

There have been no material changes in the Company’s significant accounting policies, other than the addition of accounting policies for Exchangeable Notes, derivative liabilities (the Derivative liability) and RLNs and the adoption of accounting pronouncements as described below, as compared to the significant accounting policies described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019.

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 and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. Significant estimates and assumptions reflected in these condensed consolidated financial statements include, but are not limited to, the accrual for research and development expenses, the valuation of restricted ordinary shares, the valuation of share-based compensation awards, the valuation of the RLNs and the Derivative liability. The Company bases its estimates on historical experience, known trends and other market-specific or other relevant factors that it believes to be reasonable under the circumstances. On an ongoing basis, management evaluates its estimates as there are changes in circumstances, facts and experience. Actual results could differ materially from those estimates. The Company has contemplated the impact of COVID-19 within its financial statements and is not aware of any specific event or circumstance that would require the Company to update estimates, judgments or revise the carrying value of any assets or liabilities.

Specifically, management has estimated variables used to calculate the discounted cash flow analysis (DCF) and assumptions used in the Black-Scholes and binomial lattice models to value derivative instruments (see Note 3 - Fair Value of Financial Assets and Liabilities).

Cash and Cash Equivalents

The Company’s cash and cash equivalents consist of cash balances and highly liquid investments with maturities of three months or less at the date of purchase. Accounts held at U.S. financial institutions are insured by the Federal Deposit Insurance Corporation up to $250, while accounts held at Irish financial institutions are insured under the Deposit Guarantee Scheme up to $117 (€100).

(In thousands, except share and per share data)

Cash accounts with any type of restriction are classified as restricted cash. If restrictions are expected to be lifted in the next twelve months, the restricted cash account is classified as current. Included within restricted cash on the Company’s condensed consolidated balance sheet is a certificate of deposit for $90 which is being held by a third party bank as collateral for the irrevocable letter of credit issued in March 2018 to secure an office lease (see Note 6 - Leases). Also included within restricted cash on the Company’s condensed consolidated balance sheet is $17 relating to the warrants issued on June 5, 2020 pursuant to the June 3 SPA and $19 relating to the warrants issued on July 2, 2020 pursuant to the June 30 SPA. On the closing date of each of the June 3 Offering and June 30 Offering, each investor deposited $0.01 per warrant issued being the nominal value of the underlying ordinary share represented by each warrant. This amount will be held in trust by the Company pending a decision by the relevant investor to exercise the warrant by means of a "cashless exercise" pursuant to the terms of the warrant, in which case the $0.01 will be used to pay up the nominal value of the ordinary share issued pursuant to the warrant. Upon the exercise of the warrants other than by means of a "cashless exercise", the amount held in trust will be returned to the relevant investor in accordance with the terms of the applicable SPA.

  Concentration of Credit Risk

Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents. The Company has most of its cash and cash equivalents at two accredited financial institutions in the United States and Ireland, in amounts that exceed federally insured limits. The Company did not hold any short-term investments as of September 30, 2020. The Company does not believe that it is subject to unusual credit risk beyond the normal credit risk associated with commercial banking relationships.

Net Loss Per Ordinary Share

Basic and diluted net loss per ordinary share is determined by dividing net loss attributable to ordinary shareholders by the weighted-average ordinary shares outstanding during the period in accordance with Accounting Standard Codification (ASC) 260, Earnings per Share. For the periods presented, the following ordinary shares underlying the options, unvested restricted ordinary shares, unvested restricted share units, unvested performance restricted share units and the warrants have been excluded from the calculation because they would be anti-dilutive.

Segment and Other Information

The Company determines and presents operating segments based on the information that is internally provided to the Chief Executive Officer, Chief Scientific Officer and Chief Financial Officer, who together are considered the Company’s chief operating decision maker, in accordance with ASC 280, Segment Reporting. The Company has determined that it operates as a single business segment, which is the development and commercialization of innovative treatments for drug resistant bacterial infections.

The distribution of total operating expenses by geographical area was as follows:

(In thousands, except share and per share data)

The distribution of long-lived assets by geographical area was as follows:

Exchangeable Notes

The Company evaluates its debt and equity issuances to determine if those contracts, or embedded components of those contracts, qualify as derivatives under ASC 815, Derivatives and Hedging. Where embedded exchange features are determined to be derivatives, under ASC 815-15, which requires bifurcation, these contracts are recorded at fair value and deducted from the book value of the debt host as a debt discount at inception. The debt host is subsequently measured at amortized cost. Debt discounts are recognized to interest expense over the term of the debt using the effective interest method.

Derivative Liability

The Company accounts for derivative instruments in accordance with ASC 815, which establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other financial instruments or contracts which require bifurcation and measurement at fair value for accounting purposes on the balance sheet date. Any liabilities recorded at fair value are revalued each reporting period with the resulting change in fair value reflected in other (expense) / income, net.

In determining the appropriate fair values, the Company uses a variety of valuation techniques applying DCF, Black-Scholes and binomial lattice models, which are discussed in Note 3 - Fair Value of Financial Assets and Liabilities. The Company’s derivative financial instruments consist of embedded features in the Exchangeable Notes. The embedded derivatives include provisions that provide the noteholder with certain exchange rights and protections on a fundamental change such as a change of control. The effects of interactions between embedded derivatives are calculated and accounted for in arriving at the overall fair value of the financial instruments.

Royalty-Linked Notes

The RLNs qualify as debt instruments under ASC 470, Debt, and are initially recorded at fair value, applying a DCF model, and then subsequently measured at amortized cost. The Company assesses the valuation of this debt for any significant changes to the facts and circumstances in the initial valuation which would impact the carrying value, and if required, make adjustments to revalue the debt as appropriate. Amortization is recognized as interest expense over the term of the debt instrument using the effective interest method.

Ordinary Share Warrants

The Company accounts for ordinary share warrants in accordance with applicable accounting guidance provided in ASC 815, Derivatives and Hedging – Contracts in Entity's Own Equity, as either derivative liabilities or as equity instruments depending on the specific terms of the warrant agreement. Any warrants that (i) require physical settlement or net-share settlement or (ii) provide the Company with a choice of net-cash settlement or settlement in its own shares (physical settlement or net-share settlement), provided that such warrants are indexed to the Company's own shares is classified as equity. The Company's June 3 Offering and June 30 Offering contain freestanding derivatives which satisfy the criteria for classification as equity instruments as the warrants do not contain cash settlement features or variable settlement provision that cause them to not be indexed to the Company's own stock. The Company assesses classification of its ordinary share warrants at each reporting date to determine whether the instruments still qualify for the scope exception under ASC 815.   

Income Taxes

The CARES Act lifts certain deduction limitations originally imposed by the Tax Cuts and Jobs Act of 2017 (2017 Tax Act). Corporate taxpayers may carryback net operating losses (NOLs) originating during 2018 through 2020 for up to five years, which was not previously allowed under the 2017 Tax Act. The CARES Act also eliminates the 80% of taxable income limitations by allowing corporate entities to fully utilize NOL carryforwards to offset taxable income in 2018, 2019 or 2020. Taxpayers may generally deduct interest up to the sum of 50% of adjusted taxable income plus business interest income (30% limit under the 2017 Tax Act) for tax years beginning January 1, 2019 and 2020. The CARES Act allows taxpayers with alternative minimum tax credits to claim a refund in 2020 for the entire amount of the credits instead of recovering the credits through refunds over a period of years, as originally

3. Fair Value of Financial Assets and Liabilities

The following table presents information about the Company’s financial assets that were carried at fair value on a recurring basis on the condensed consolidated balance sheet as of September 30, 2020 and December 31, 2019 and indicates the fair value hierarchy of the valuation inputs utilized to determine such fair value.

The other asset above relates to advance payments made to a supplier that were recorded at fair value using DCF analysis as of September 30, 2020 and December 31, 2019. The fair value measurements of these advance payments were determined based on significant unobservable inputs, including discount rates of 21% and 15%, as of September 30, 2020 and December 31, 2019, respectively, and the expected time to recovery of the payment. Changes to the inputs described above are not expected to have a material impact on the Company’s financial position and results of operations in any given period.

The carrying amounts reported in the condensed consolidated balance sheets for prepaid expenses and other current assets, accounts payable, accrued expenses and other current liabilities approximate their fair value based on the short-term maturity of these instruments.

The following table presents information about the Company’s debt, Exchangeable Notes, Derivative liability and RLNs. The Company’s long-term debt were carried at amortized cost on the condensed consolidated balance sheet as of September 30, 2020 and December 31, 2019 and indicates the fair value hierarchy of the valuation inputs utilized to determine the approximate fair value:

The book value of the current portion of long-term debt approximates its fair value due to the short-term nature of the balance. The fair value of long-term debt, less current portion were determined using DCF analysis using quoted market interest rates, without consideration of transaction costs, which represents a Level 2 basis of fair value measurement. The counterparty to the long-term debt is a major international financial institution.

The fair value of long-term Exchangeable Notes were determined using DCF analysis using the fixed interest rate outlined in the Exchangeable Note indenture, without consideration of transaction costs, which represents a Level 2 basis of fair value measurement.

The Level 3 liabilities held as of September 30, 2020 consist of the embedded exchange option and change of control premium contained in the Exchangeable Notes (see Note 8 - Debt) and a separate financial instrument, that was issued as part of the Units, the RLNs (see Note 9 – Royalty-Linked Notes). The exchange option and change of control premium met the criteria requiring these to be bifurcated and accounted for separately from the host debt in accordance with ASC 815-15, Derivatives and Hedging; Embedded Derivatives. The exchange option and change of control premium are presented as a Derivative liability. At any time on or after January 21, 2021, subject to specified limitations, the Exchangeable Notes are exchangeable for the Company’s ordinary shares, cash or a combination of ordinary shares and cash, at an initial exchange rate of 1,000 shares per $1,000 of principal and interest on the Exchangeable Notes (equivalent to an initial exchange price of approximately $1.00 per ordinary share), which exchange rate was adjusted to 1,286.1845 shares per $1,000 principal and interest on the Exchangeable Note (equivalent to an exchange price of approximately $0.7775 per ordinary share) as of November 2, 2020 and is subject to further adjustment pursuant to the terms of the indenture governing the Exchangeable Notes. The Derivative liability, representing the exchange option and change of control premium, was recorded at a fair value of $27,038 upon issuance of the Exchangeable Notes under the Private Placement and is subsequently remeasured to fair value at the end of each reporting period. The fair value of the exchange option at September 30, 2020 amounted to $12,791.

In the event of a fundamental change that is not a liquidation event (Fundamental Change), under the Exchangeable Note indenture, the Company will be required to pay the holder of the Exchangeable Notes the greater of three times the outstanding principal amount of such Exchangeable Note and the consideration that would be received by the holder of such Exchangeable Note, in connection with such Fundamental Change, if the holder had exchanged its note for ordinary shares immediately prior to the consummation of such Fundamental Change, plus any accrued and unpaid interest. The Derivative liability, representing the change of control feature, was recorded at a fair value of $13,306 at September 30, 2020.

The fair value of each component of the Derivative liability was determined using a valuation technique applying DCF analysis or Black-Scholes in combination with binomial lattice models, without consideration of transaction costs, which represents a Level 3 basis of fair value measurement. The key inputs to valuing the Derivative liability as of September 30, 2020 include the

11

Notes to Unaudited Condensed Consolidated Financial Statements

(In thousands, except share and per share data)

indenture terms of the Exchangeable Notes, the Company’s share price at the exchange date, the expected annual volatility of the Company’s ordinary shares, management’s assumption regarding the probability of a fundamental change pursuant to the terms of the Exchangeable Notes indenture, and a risk-adjusted discount rate. Fair value measurements are highly sensitive to changes in these inputs and significant changes in these inputs could result in a significantly higher or lower fair value.

The following table presents the changes in fair value of the Company's Derivative liability for the nine months ended September 30, 2020

The following summary table shows the assumptions used in the Black-Scholes and binomial lattice pricing models to estimate the fair value of the exchange option:

The significant assumptions used in the DCF model, to estimate the fair value of the change of control feature at September 30, 2020, were a discount rate of 21% and management’s assumption regarding the probability of a fundamental change pursuant to the terms of the Exchangeable Notes indenture.

 The RLN liability is carried at amortized cost on the condensed consolidated balance sheet as of September 30, 2020 (see Note 9 – Royalty-Linked Notes). The book value of the current portion of the RLN liability approximates its fair value due to the short-term nature of the balance. The total fair value of $15,782 was determined using DCF analysis, without consideration of transaction costs, which represents a Level 3 basis of fair value measurement. The key inputs to valuing the RLNs were the indenture terms of the RLNs, the expected cash flows to be received by holders of the RLNs based on management’s revenue forecasts of U.S. sulopenem sales and a risk-adjusted discount rate to derive the net present value of expected cash flows. The RLNs will be subject to a maximum return amount, including all principal and payments and certain default interest in respect of uncurable defaults, of $160.00 (or 4,000 times the principal amount of such note). The discount rate applied to the model was 21%. The book value of the current portion of the RLN liability approximates its fair value due to the short-term nature of the balance. Fair value measurements are highly sensitive to changes in these inputs and significant changes in these inputs could result in a significantly higher or lower fair value.

There have been no transfers of assets or liabilities between the fair value measurement levels.

4. Prepaid Expenses and Other Current Assets

Prepaid expenses and other current assets consist of the following:

5. Property and Equipment

Property and equipment and related accumulated depreciation are as follows:

Depreciation expense was $122 for the nine months ended September 30, 2020 and $152 for the year ended December 31, 2019.

6. Leases

The Company has entered into a number of operating leases, primarily for office space and commercial property. These leases have terms which range from four to 19 years, and generally include one or more options to terminate or renew. The termination options can reduce the lease term for periods ranging from two to 10 years, however the remaining lease terms do not represent these early termination dates as management have concluded that it is reasonably certain that the Company will not exercise these options. The renewal terms can extend the lease term for additional periods ranging from three to five years. These renewal options are represented in the remaining lease term as management have concluded that it is reasonably certain that the Company will exercise the renewal option. In September 2020, the Company entered into a sublease agreement for commercial property. This sublease has a term of three years. Certain leases contain variable lease payments, including payments based on an index or rate. Variable lease payments based on an index or rate are initially measured using the index or rate in effect at lease commencement. Certain agreements contain both lease and non-lease components. The Company has elected to separately account for these components in determining the lease liabilities and right-of-use assets. The Company’s lease agreements generally do not provide an implicit borrowing rate; therefore, an internal incremental borrowing rate was determined based on information available at lease commencement date for the purposes of determining the present value of lease payments. The Company used the incremental borrowing rate on January 1, 2019 for all leases that commenced prior to that date. All operating lease expenses are recognized on a straight-line basis over the lease term. The Company recognized $736 and $760 of operating lease costs for right-of-use assets during the nine months ended September 30, 2020 and 2019, respectively. The Company recognized $26 of sublease income during the nine months ended September 30, 2020. The Company was not party to any sublease agreement during the nine months ended September 30, 2019.  

Information related to the Company’s right-of-use assets and related lease liabilities is as follows:

8. Debt

Secured Credit Facility

On April 27, 2018, the Company’s subsidiaries, Iterum Therapeutics International Limited, Iterum Therapeutics US Holding Limited and Iterum Therapeutics US Limited (the Borrowers), entered into a loan and security agreement (Loan and Security Agreement) with SVB pursuant to which SVB agreed to lend the Borrowers up to $30,000 in two term loans. $15,000 of the secured credit facility was funded on closing. A second draw of up to $15,000 was available to the Company through October 31, 2019, upon satisfaction of either of the following: (i) the achievement by the Company of both non-inferiority and superiority primary endpoints from its Phase 3 uncomplicated urinary tract infection (uUTI) trial, as well as reporting satisfactory safety data from the trial, or (ii) the achievement of non-inferiority primary endpoints from both its Phase 3 uUTI and complicated urinary tract infection (cUTI) trials, as well as reporting satisfactory safety data from the trials. A non-utilization fee of 1.50% of the aggregate undrawn principal amount was to apply if the Company satisfied the above conditions but chose not to draw down the second term loan. The Company did not satisfy the conditions for the second draw above before the deadline of October 31, 2019.

Required monthly amortization payments for the initial $15,000 draw commenced on November 1, 2019 and total principal repayments of $4,655 were made during the nine months ended September 30, 2020. Interest accrues at a floating per annum rate equal to the greater of (i) 8.31%; or (ii) 3.89% above the Wall Street Journal prime rate, and is payable monthly in arrears. All outstanding principal, plus a 4.20% final interest payment, will be due and payable on the earliest to occur of March 1, 2022 (the maturity date), the acceleration of the term loan or the prepayment of the term loan. The final payment fee of $630, which represents 4.2% of the funded loan, is accreted using the effective interest method over the life of the loan as interest expense. Voluntary prepayments are permitted at any time, subject to a prepayment fee of 4.00% in the first year, 3.00% in the second year, and 2.00% thereafter.

In connection with the initial $15,000 draw, the Company issued SVB and Life Sciences Fund II LLC (LSF) warrants to purchase an aggregate of 19,890 Series B convertible preferred shares (which converted into warrants to purchase 19,890 ordinary shares upon the Company’s initial public offering (IPO)) at an exercise price of $18.85 per share. If the second term loan had been drawn down, each of SVB and LSF would have been automatically entitled to purchase additional ordinary shares in an aggregate amount equal to 2.50% of the second term loan divided by the applicable exercise price.

The loan proceeds were allocated based on the relative fair values of the debt instrument and the warrant instrument. The fair value of the warrants and the closing costs were recorded as debt discounts and are being amortized using the effective interest rate method over the term of the loan. The effective annual interest rate of the outstanding debt is approximately 12.51% as of September 30, 2020. The Company recognized $1,091 and $1,310 of interest expense related to the loan agreement during the nine months ended September 30, 2020 and 2019, respectively, including $324 and $243 related to the accretion of the debt discounts and deferred financing costs during the nine months ended September 30, 2020 and 2019, respectively.

In connection with the Private Placement, Iterum Bermuda was joined as a party to the Loan and Security Agreement as a borrower and the Loan and Security Agreement was amended on January 16, 2020 to, among other things, modify the definition of subordinated debt to include the RLNs and Exchangeable Notes.

2025 Exchangeable Notes

On January 21, 2020, the Company completed a Private Placement pursuant to which its wholly owned subsidiary, Iterum Bermuda issued and sold approximately $51.6 million aggregate principal amount of 6.500% Exchangeable Notes and $0.1 million aggregate principal amount of RLNs, to a group of accredited investors. On September 8, 2020, the Company completed a Rights Offering pursuant to which Iterum Bermuda issued and sold approximately $0.2 million aggregate principal amount of 6.500% Exchangeable Notes and $0.02 million aggregate principal amount of RLNs, to existing shareholders. The Securities were sold in Units with each Unit consisting of an Exchangeable Note in the original principal amount $1,000 and 50 RLNs. The Units were sold at a price of $1,000 per Unit.  

At any time on or after January 21, 2021, subject to specified limitations, the Exchangeable Notes are exchangeable for the Company’s ordinary shares, cash or a combination of ordinary shares and cash, at the Company’s election, at an initial exchange rate of 1,000 shares per $1,000 of principal and interest on the Exchangeable Notes (equivalent to an initial exchange price of approximately $1.00 per ordinary share), which exchange rate was adjusted to 1,286.1845 shares per $1,000 principal and interest on the Exchangeable Note (equivalent to an exchange price of approximately $0.7775 per ordinary share) as of November 2, 2020 and is subject to further adjustment pursuant to the terms of the indenture governing the Exchangeable Notes. Any accrued and unpaid interest being exchanged will be calculated to include all interest accrued on the Exchangeable Notes being exchanged to, but excluding, the exchange settlement date.

In addition, the Exchangeable Notes will become due and payable by the Company upon the occurrence of a Fundamental Change as defined in the Exchangeable Notes indenture. The Company will be required to pay the holder of the Exchangeable Notes the greater of three times the outstanding principal amount of such Exchangeable Note and the consideration that would be received by the holder of such Exchangeable Note in connection with such Fundamental Change if the holder had exchanged its note for ordinary shares immediately prior to the consummation of such Fundamental Change, plus any accrued and unpaid interest.

The Company evaluates its debt and equity issuances to determine if those contracts, or embedded components of those contracts, qualify as derivatives under ASC 815-15, Derivatives and Hedging, requiring separate recognition in the Company’s financial statements. The Company evaluated the accounting for the issuance of the Exchangeable Notes and concluded that the embedded exchange option and change of control feature are considered a Derivative liability under ASC 815-15 requiring bifurcation, from the Exchangeable Notes, as it does not qualify for the scope exceptions for contracts in an entity’s own equity given the terms of the Exchangeable Notes. The exchange option and change of control feature are accounted for as a Derivative liability, under ASC 815-15, and are required to be separated and recorded as a single liability, which is revalued each reporting period with the

resulting change in fair value reflected in other (expense) / income, net, in the condensed consolidated statements of operations and comprehensive loss.         

The fair value of the Derivative liability at January 21, 2020 was $27,038, and the fair value of the Derivative liability related to the Rights Offering was $82,both of which were recorded as a reduction to the book value of the host debt contract. This debt discount is being amortized to interest expense over the term of the debt using the effective interest method. Transaction costs amounting to $2,815 were allocated to the exchange option. These costs are reflected in financing transaction costs in the condensed consolidated statements of operations and comprehensive loss for the nine months ended September 30, 2020. Transaction costs amounting to $2,814 were allocated to the debt host and capitalized in the host debt book value.    

In circumstances where the embedded exchange option in a co
