Omeros Corporation Reports Second Quarter 2025 Financial Results

鈥� Conference Call Today at 4:30 p.m. ET

SEATTLE--(BUSINESS WIRE)-- Omeros Corporation (Nasdaq: OMER) today announced recent highlights and developments as well as financial results for the second quarter ended June 30, 2025, which include:

• Net loss for the second quarter of 2025 was $25.4 million, or $0.43 per share, compared to a net loss of $56.0 million, or $0.97 per share for the second quarter of 2024. For the six months ended June 30, 2025, our net loss was $58.9 million, or $1.01 per share, compared to a net loss of $93.2 million, or $1.60 per share in the corresponding prior year period. The reduction in net loss from the prior year quarter was primarily related to narsoplimab drug substance manufacturing expenses incurred in the prior year quarter.
• At June 30, 2025, we had $28.7 million of cash and short-term investments. On July 28, 2025, we received $20.6 million in cash proceeds net of offering expenses from Polar Asset Management Partners in exchange for 5,365,853 shares of our common stock sold in a registered direct offering at a price of $4.10 per share, representing a 14 percent premium to the closing price of our common stock on the day of pricing.
• In March 2025, we resubmitted to the U.S. Food and Drug Administration (鈥淔DA鈥�) our Biologics License Application (鈥淏LA鈥�) seeking regulatory approval for narsoplimab in hematopoietic stem cell transplant-associated thrombotic microangiopathy (鈥淭A-TMA鈥�). The resubmission was accepted for review by FDA as a class 2 resubmission and, pursuant to the Prescription Drug User Fee Act (鈥淧DUFA鈥�), was assigned an initial target action date for the FDA decision of September 25, 2025. Following the submission of information in response to an information request from FDA, the Agency informed the Company that the PDUFA date has been extended to December 26, 2025. FDA stated that, assuming no major deficiencies are identified during its review, labeling discussions are planned to begin no later than October 2025. We continue to work with FDA as it advances its review process. To date, all analyses requested by FDA as part of its review have been consistent with and have provided statistically significant support of narsoplimab鈥檚 benefit demonstrated in the analyses submitted as part of the BLA resubmission.
• In June 2025, we submitted our marketing authorization application (鈥淢AA鈥�) for narsoplimab in TA-TMA to the European Medicines Agency (鈥淓MA鈥�). EMA has completed validation of the MAA, which confirms that the submission is accepted and starts the formal review process by EMA鈥檚 Committee for Medicinal Products for Human Use. We expect the committee to render its opinion on the MAA in mid-2026.
• On May 14, 2025, we completed a transaction with certain holders of our convertible senior notes due February 15, 2026 (the 鈥�2026 Notes鈥�) in which we exchanged $70.8 million aggregate principal amount of 2026 Notes on a one-for-one basis for newly issued convertible senior notes due on June 15, 2029 (the 鈥�2029 Notes鈥�). Also, on May 12, 2025, we entered into an equitization transaction whereby two affiliated holders agreed to convert an additional $10.0 million principal amount of 2026 Notes into shares of our common stock at prices determined based in part on the closing price of the Company鈥檚 common stock on May 9, 2025 and in part based on the 20-day VWAP applicable to each tranche conversion date, subject to a floor conversion price.
  • After giving effect to these transactions, the aggregate principal balance of our 2026 Notes was reduced from $97.9 million to $17.1 million. These transactions eliminated the need for us to make a $20.0 million prepayment of our outstanding secured term debt along with a $1.0 million prepayment premium, which, under our Credit and Guaranty Agreement, would have been required to be paid in November 2025 to avoid accelerated maturity of the entire term debt balance.
• As previously disclosed, we are in discussions regarding potential asset acquisition and/or licensing agreements in connection with certain of our clinical assets. The most advanced of these discussions relates to an agreement with a potential multi-billion total transaction value exclusive of royalties. Upon closing this transaction, we would expect to receive an upfront cash payment that would (1) provide for the repayment in full of the $67.1 million term loan outstanding under our Credit and Guaranty Agreement, as well as related prepayment premiums, (2) allow for repayment at or prior to maturity of the $17.1 million remaining principal balance of our 2026 Notes, and (3) provide sufficient additional capital for more than 12 months of post-closing operations. We expect this transaction would also include near- and longer-term milestones that could provide substantial additional capital and, if regulatory approval is obtained, sales-based milestones and royalties from commercial sales. The Company can provide no assurance that any such transaction will be consummated on favorable terms or at all.

鈥淒uring the second quarter, we significantly improved our balance sheet, reducing our near-term debt by more than $100 million and adding new capital from a long-horizon investor through an equity financing with Polar Asset Management,鈥� said Gregory A. Demopulos, M.D., Omeros鈥� Chairman and Chief Executive Officer. 鈥淲orking closely with FDA, we continue preparing for the anticipated approval and subsequent launch of narsoplimab in TA-TMA, an indication with an increasingly large and recognized unmet need for which there is no approved treatment. NIDA has committed to continue funding our PDE7 inhibitor program OMS527, which is being developed to become the first therapeutic for cocaine use disorder and potentially for addictive and compulsive disorders broadly. Our OncotoX-AML program remains on track to enter the clinic in the next 18-24 months and all data generated with the lead compound look promising, showing marked improvement over the current AML standard of care. Currently paused to prioritize narsoplimab, our lead MASP-3 inhibitor zaltenibart and our long-acting MASP-2 inhibitor OMS1029 stand ready to initiate Phase 3 and Phase 2 clinical trials, respectively. With substantial industry interest across our assets, partnering discussions continue advancing, and we see a number of potential value-driving milestones lining up nicely throughout the remainder of 2025 and into 2026.鈥�

Second Quarter and Recent Developments

• Recent developments regarding narsoplimab, our lead monoclonal antibody targeting mannan-binding lectin-associated serine protease-2 (鈥淢ASP-2鈥�), include the following:
  • We expect to be well-positioned to drive demand in our highest-priority transplant centers upon the anticipated approval of narsoplimab for TA-TMA. These centers are already actively monitoring for signs and symptoms of TA-TMA and their transplant physicians are familiar with narsoplimab and its clinical profile. We鈥檙e executing a phased onboarding of hematology-experienced sales professionals so that we can first reach the highest-volume transplant centers and expand more broadly over time. Our sales leadership is currently in active discussions with top-tier candidates with deep expertise in transplant and rare hematologic diseases. Many of these candidates have been closely following narsoplimab鈥檚 development and are enthusiastic to launch a product with the potential to significantly improve outcomes and save patients鈥� lives.
  • We are engaging in pre-approval information exchanges with hospital formulary decision-makers and payers in support of their planning for coverage and reimbursement ahead of narsoplimab鈥檚 anticipated approval. Feedback has been highly encouraging 鈥� stakeholders recognize the strong clinical safety and efficacy data for narsoplimab and are eager for an approved treatment option that avoids the risks associated with off-label C5 inhibitors.
  • Two manuscripts detailing narsoplimab鈥檚 safety and survival benefits in high-risk TA-TMA patients have been submitted for publication in premier peer-reviewed journals. The first, already accepted for publication, assesses survival in both adults and children treated with narsoplimab under Omeros鈥� expanded access program; the other is under review and compares survival of adult TA-TMA patients treated with narsoplimab in the completed pivotal trial of narsoplimab and Omeros鈥� expanded access program to a well-matched external control.
  • A retrospective single center case-control study was published last month in the American Journal of Hematology highlighting the association of the C5 inhibitor eculizumab with increased rates of infection and infection-related mortality in pediatric TA-TMA patients. The study found that pediatric patients treated with eculizumab had significantly higher infection rates and infection-related mortality. Specifically, bacteremia infections were 8.5-fold higher, and estimated one鈥憏ear infection-related mortality was sixfold higher.
• Recent developments regarding OMS527, our phosphodiesterase 7 (鈥淧DE7鈥�) inhibitor program focused on addictions and compulsive disorders as well as movement disorders, include:
  • The Company was previously awarded a grant from the National Institute on Drug Abuse (鈥淣IDA鈥�), part of the National Institutes of Health, to develop, at NIDA鈥檚 request, its lead orally administered phosphodiesterase 7 (鈥淧DE7鈥�) inhibitor compound for the treatment of cocaine use disorder. NIDA awarded the grant to us for a total of $6.24 million over three years, of which the Company has claimed and received $1.5 million of funding to date. The grant is intended to support (i) preclinical cocaine interaction/toxicology studies to assess safety of the therapeutic candidate in the presence of concomitant cocaine administration and (ii) an in-patient, placebo-controlled clinical study evaluating the safety and effectiveness of OMS527 in adult cocaine users who receive concurrent intravenous cocaine. The preclinical studies, designed by NIDA toxicologists, have been successfully completed with no safety findings and provide drug-interaction safety data in support of the planned in-patient human study of OMS527 in cocaine users. FDA has requested that the Company provide additional preclinical information prior to initiating the clinical in-patient study in cocaine users, which we target for the first part of 2026.
• Recent developments regarding our oncology platform comprising signaling-driven immunomodulators, oncotoxins, and an adoptive T-cell technology combined with an immunostimulator, include:
  • We have continued to advance IND-enabling work in our OncotoX biologics program focused on acute myeloid leukemia (鈥淎ML鈥�). We have limited the scope of these recent efforts in order to preserve available capital for use in other programs. We estimate that our OncotoX-AML therapeutic could enter the clinic in 18-24 months.
  • We expect to draw on the resources of our recently established Oncology Clinical Steering Committee to advance development of Omeros鈥� OncotoX-AML program. The clinical steering committee is composed of leaders in AML treatment and research at the premier cancer centers across the United States and its members are expected to share insights and help guide development of our potential AML therapeutic. In both in vivo 鈥� in immunocompromised mice with human tumors 鈥� and in vitro models with human cell lines, our OncotoX-AML therapeutic has consistently demonstrated superior efficacy to current AML standard of care treatments. OncotoX-AML shows broad application across AML regardless of genetic mutation including TP53, NPM1, KMT2A, and FLT3.

Financial Results

Net loss for the second quarter of 2025 was $25.4 million, or $0.43 per share, compared to a net loss of $56.0 million, or $0.97 per share for the second quarter of 2024. For the six months ended June 30, 2025, our net loss was $58.9 million, or $1.01 per share, compared to a net loss of $93.2 million, or $1.60 per share in the prior year period. The prior year quarter included cash outlays related to manufacturing of narsoplimab drug substance.

At June 30, 2025, we had $28.7 million of cash and short-term investments. Pursuant to a covenant in the Credit Agreement entered into on June 3, 2024 in relation to our secured term debt, we must maintain $25.0 million of unrestricted cash, cash equivalents, and short-term investments at all times.

On July 28, 2025, we received $20.6 million in cash proceeds net of offering of expenses from Polar Asset Management Partners in exchange for 5,365,853 shares of our common stock in a registered direct offering at a price of $4.10 per share, representing a 14 percent premium to the closing price of our common stock on the day of pricing. Additionally, we have an at-the-market equity offering facility through which we may, from time to time, offer and sell shares of our common stock for aggregate gross proceeds of up to $150.0 million (the 鈥淎TM Facility鈥�). Subsequent to June 30, 2025 and through August 14, 2025, we have received $2.1 million in gross proceeds from sales of common stock through the ATM Facility.

For the second quarter of 2025, we earned OMIDRIA royalties of $8.6 million on Rayner Surgical Inc.鈥檚 (鈥淩ayner鈥�) U.S. net sales of $28.6 million. This compares to earned OMIDRIA royalties of $10.9 million during the second quarter of 2024 on U.S. net sales of $36.4 million. Per the terms of our original 2022 and amended 2024 agreements with DRI Health Acquisition LP, (鈥淒RI鈥�), all U.S. based royalties through 2031 are remitted from Rayner to DRI through an escrow agent.

Total operating expenses for the second quarter of 2025 were $32.4 million compared to $59.2 million for the second quarter of 2024. The $26.8 million decrease was primarily driven by two factors: first, the prior-year quarter included $17.6 million in cash outlays related to the manufacturing of narsoplimab drug substance and, second, we temporarily suspended or paused certain activities and programs to prioritize available capital to support the commercial launch of narsoplimab following its anticipated FDA approval and the completion of some of our ongoing clinical trials.

Interest expense during the second quarter of 2025 was $15 thousand compared to $9.2 million during the prior year quarter. The $9.2 million decrease was due to a non-cash remeasurement adjustment of our OMIDRIA royalty obligation to DRI to reflect changes in royalty estimates from Rayner.

During the second quarter of 2025, we earned $1.2 million in interest and other income compared to $3.2 million in the second quarter of 2024. The difference is primarily due to lower cash and investments available to invest in the current quarter.

As a result of the exchange of our 2026 Notes for 2029 Notes which occurred in May 2025, we realized a $3.0 million non-cash loss on extinguishment of our convertible senior notes. The extinguishment reflects marking-to-market the 2029 Notes and the expensing of capitalized debt issuance costs on the retired portion of the 2026 Notes.

Net income from discontinued operations, net of tax, was $0.5 million, or $0.01 per share, in the second quarter of 2025 compared to $9.1 million, or $0.15 per share, in the second quarter of 2024. The decrease was primarily attributable to a non-cash remeasurement of our OMIDRIA contract royalty asset in the current quarter to reflect changes in royalty estimates from Rayner.
