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 and convertible preferred shares, debt raised under a financing arrangement with Silicon Valley Bank (SVB), 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 pursuant to which its wholly owned subsidiary, Iterum Therapeutics Bermuda Limited (Iterum Bermuda), issued and sold approximately $51.6 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, Royalty-Linked Notes and, together with the Exchangeable Notes, the Securities) to a group of accredited investors. 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 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 significant additional research and development efforts, including preclinical and clinical testing and 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, 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) with each Unit consisting of an Exchangeable Note in the original principal amount of $1,000 and 50 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 approximately $1.00 per ordinary share), subject to specified limitations. 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 sale of the Securities of approximately $46.4 million, after deducting placement agent fees and offering expenses.

In connection with the Private Placement, the Company agreed to undertake an offering of subscription rights to purchase additional Units (the Rights Offering) on a pro rata basis to its shareholders who did not participate in the Private Placement.

On April 3, 2020 the U.S. Small Business Administration (SBA) launched a Paycheck Protection Program (the Program) established following the signing of the Coronavirus Aid, Relief and Economic Security Act (CARES Act) on March 27, 2020. On April 30, 2020, the Company’s wholly owned subsidiary, Iterum Therapeutics US Limited, (the Borrower) entered into a note 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 during 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 note 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 payroll costs and other designated operating expenses for up to eight weeks, provided at least 75% of the loan proceeds are used for payroll costs. The Company expects to incur qualifying payroll costs and other operating expenses in the eight weeks from April 30, 2020 such that the Company may be able to request forgiveness of some portion of the loan from the Lender.

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, debt raised under its financing arrangement with SVB, payments received under the CARB-X program and the proceeds of the Private Placement. The Company has incurred operating losses since inception, including net losses of $16,100 and $20,580 for the three months ended March 31, 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 $251,023 as of March 31, 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.

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 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.
