--Registration Trial for uUTI Planned in Second Half of 2022--
--Cash Runway into 2024--

--Company to host conference call today at 8:30am ET--

DUBLIN, Ireland and CHICAGO, March 28, 2022 (GLOBE NEWSWIRE) -- Iterum Therapeutics plc (Nasdaq: ITRM), a clinical-stage pharmaceutical company focused on developing next generation oral and IV antibiotics to treat infections caused by multi-drug resistant pathogens in both community and hospital settings, today reported financial results for the fourth quarter and year ended December 31, 2021.

“Based on several recent interactions with the FDA, we believe that we have made progress towards an agreement on the additional Phase 3 trial design required to support the resubmission of our NDA for oral sulopenem in uUTI. Subject to finalization of the clinical program, we expect to start the study in the second half of 2022,” said Corey Fishman, Iterum’s Chief Executive Officer. “Based on the current operating plan, which includes an additional Phase 3 study, we believe that we are well positioned financially to fund operations into 2024 with our existing cash resources.”

Highlights and Recent Events

• Reduced outstanding debt: We completed the repayment of our term loan with Silicon Valley Bank in March 2022.
• Received 180-day extension of Nasdaq listing deficiency: On March 9, 2022, we received written notification from Nasdaq that a 180-day extension to regain compliance with Nasdaq's minimum bid price requirement was granted. We now have until September 5, 2022 to meet this requirement.
• Published two articles in scientific journals: In February 2022, we published two articles highlighting anti-bacterial resistance and the unmet medical need for new oral agents for urinary tract infections. The articles can be accessed under “Scientific Publications” in the Our Science section of the Company’s website at www.iterumtx.com.
  
  

Fourth Quarter and Full Year 2021 Financial Results

Cash, cash equivalents and short-term investments was $81.3 million at December 31, 2021. Based on the current operating plan and subject to final determination of the design and planned conduct of potential additional clinical and non-clinical development of sulopenem, Iterum expects that its current cash, cash equivalents and short-term investments will be sufficient to fund its operations into 2024. As of February 28, 2022, we had approximately 182.8 million ordinary shares outstanding.

Research and development (R&D) expenses for the fourth quarter and full year 2021 were $3.7 million and $10.7 million, respectively, compared to $2.4 million and $21.1 million for the same periods in 2020. The increase for the three-month period was primarily due to the non-cash amortization of an intangible asset in 2021. The decrease in R&D expenses for the full year was primarily due to the completion of Iterum’s Phase 3 trials in 2020.

General and administrative (G&A) expenses for the fourth quarter and full year 2021 were $3.1 million and $13.8 million, respectively, compared to $2.3 million and $11.1 million for the same periods in 2020. The increase for three-month period was primarily due to an increase in share-based compensation, and the increase in G&A expense for the full year was primarily due to higher spend on pre-commercialization activities in the first half of 2021 and higher share-based compensation expense, partially offset by lower G&A headcount.

Adjustments to the fair value of derivatives for the fourth quarter and full year 2021 were $3.6 million and ($61.0) million, compared to ($2.7) million and ($1.7) million for the same periods in 2020. The non-cash adjustment in the fourth quarter of 2021 primarily related to a decrease in the value of the derivative components associated with Iterum’s 6.500% Exchangeable Senior Subordinated Notes due 2025 (the Exchangeable Notes) as a result of a decrease in the price of its ordinary shares and market capitalization during the period. The non-cash adjustment for the full year was largely due to the fair value adjustments recorded at the time of conversion of $39.2 million of the Exchangeable Notes in 2021.

Net loss for the fourth quarter and full year 2021 was $4.2 million and $91.6 million, respectively, compared to a net loss of $11.2 million and $52.0 million for the same periods in 2020. Non-GAAP¹ net loss for the fourth quarter and full year 2021 of $3.3 million and $19.4 million, respectively, compared to a non-GAAP¹ net loss of $4.4 million and $30.9 million for the same periods in 2020.

Non-GAAP Financial Measures

To supplement Iterum’s financial results presented in accordance with U.S. generally accepted accounting principles (“GAAP”), Iterum presents non-GAAP net loss and non-GAAP net loss per share to exclude from reported GAAP net loss and GAAP net loss per share, intangible asset amortization ($1.7 million and $1.7 million); share-based compensation expense ($2.0 million and $4.3 million); the interest expense associated with accrued interest on the Exchangeable Notes, payable in cash, shares or a combination of both upon exchange, redemption or at January 31, 2025 (“the Maturity Date”), whichever is earlier ($0.2 million and $1.1 million); the non-cash amortization of the Exchangeable Notes and Royalty-Linked Notes ($0.6 million and $4.1 million); and the non-cash adjustments to the fair value of derivatives ($3.6 million and $61.0 million) for the three and twelve months ended December 31, 2021, respectively, and share-based compensation expense ($0.1 million and $2.8 million); the interest expense associated with accrued interest on the Exchangeable Notes payable in cash, shares or a combination of both upon exchange, redemption or at the Maturity Date, whichever is earlier ($0.8 million and $3.2 million); the non-cash amortization of the Exchangeable Notes and Royalty-Linked Notes ($3.1 million and $10.5 million); one-time, non-capitalized financing transaction costs ($0.0 million and $2.8 million); and the non-cash adjustments to the fair value of derivatives ($2.8 million and $1.7 million) for the three and twelve months ended December 31, 2020, respectively.

Iterum believes that the presentation of non-GAAP net loss and non-GAAP net loss per share, when viewed with its results under GAAP and the accompanying reconciliation, provides useful supplementary information to, and facilitates additional analysis by, investors, analysts, and Iterum’s management in assessing Iterum’s performance and results from period to period. These non-GAAP financial measures closely align with the way management measures and evaluates Iterum’s performance. These non-GAAP financial measures should be considered in addition to, and not a substitute for, or superior to, net loss or other financial measures calculated in accordance with GAAP. Non-GAAP net loss and non-GAAP net loss per share are not based on any standardized methodology prescribed by GAAP and represents GAAP net loss, which is the most directly comparable GAAP measure, adjusted to exclude intangible asset amortization; share-based compensation expense; the interest expense associated with accrued interest on the Exchangeable Notes payable in cash, shares or a combination of both upon exchange, redemption or at the Maturity Date, whichever is earlier; the non-cash amortization of the Exchangeable Notes and Royalty-Linked Notes; one-time, non-capitalized financing transaction costs and the non-cash adjustments to the fair value of derivatives for the three and twelve months ended December 31, 2021 and December 31, 2020. Because of the non-standardized definitions of non-GAAP financial measures, non-GAAP net loss and non-GAAP net loss per share used by Iterum Therapeutics in this press release and accompanying tables has limits in its usefulness to investors and may be calculated differently from, and therefore may not be directly comparable to, similarly titled measures used by other companies. A reconciliation of non-GAAP net loss to GAAP net loss and non-GAAP net loss per share to GAAP net loss per share have been provided in the tables included in this press release.
