First Quarter and Recent Highlights
● In January 2026, we launched YARTEMLEA in the U.S. market. During the quarter, gross product sales were $11.1 million and associated net sales, after deduction of wholesaler distribution fees and chargebacks, were $9.9 million.
● Net income for the first quarter of 2026 was $56.1 million, or $0.78 per share, compared to a net loss of $33.5 million, or $0.58 per share, for the first quarter of 2025.
● First quarter results include a $73.1 million non-cash gain associated with the mark-to-market adjustment on the embedded derivatives related to our 2029 unsecured convertible notes (the "2029 Notes"). Excluding the non-cash change in our embedded derivatives, non-GAAP adjusted net loss for the three months ended March 31, 2026 was $17.1 million, or $0.24 per share.
● At March 31, 2026, we had $135.3 million of cash and short-term investments. This balance includes the February 2026 repayment at maturity of the remaining $17.1 million aggregate principal amount of our 2026 unsecured convertible notes (the "2026 Notes"). Following that repayment, our only remaining debt outstanding is $70.8 million aggregate principal amount of our 2029 Notes, which mature in June 2029.
● In April, the U.S. Centers for Medicare & Medicaid Services ("CMS") assigned a permanent Healthcare Common Procedure Coding System J-code specific for YARTEMLEA. This simplifies billing and reimbursement across payors. The J-code becomes effective on July 1, 2026. Also in April, CMS, in its Inpatient Prospective Payment System proposed rule, recommended approval of the New Technology Add-On Payment ("NTAP") for YARTEMLEA. NTAP provides additional payments to hospitals for certain high-cost, innovative technologies, helping bridge the gap until standard payment systems incorporate them. The final rule is expected in August, with NTAP expected to be effective October 1, 2026.
"The launch of YARTEMLEA has changed the trajectory of Omeros, both operationally and financially," said Gregory A. Demopulos, M.D., Omeros’ Chairman and Chief Executive Officer. "We are seeing strong early adoption across transplant centers, expanding formulary access, favorable reimbursement support, and growing physician experience with the first and only approved treatment for TA-TMA. At the same time, our Novo Nordisk transaction has strengthened our balance sheet and accelerated advancement of our pipeline, including next-generation MASP-2 programs, OncotoX-AML, OMS527 for cocaine use disorder under NIDA funding, and our T-CAT platform targeting multidrug-resistant pathogens. The progress achieved this quarter further demonstrates the strength of our science and the value we are creating across Omeros."
Recent Developments
● YARTEMLEA and our other MASP-2 inhibitor programs
o A marketing authorization application ("MAA") for YARTEMLEA for the treatment of TA-TMA is currently under review by the European Medicines Agency ("EMA") with a decision expected in mid-2026. If approved, the MAA authorizes the product to be marketed in all EU member states and European Economic Area countries.
o We are assessing opportunities for YARTEMLEA across indications involving lectin pathway activation, including acute respiratory distress syndrome (ARDS), sickle cell disease, acute kidney injury, solid organ transplant-related TMA, and delayed graft function.
o In parallel, we are finalizing selection of an indication for a Phase 2 clinical program for OMS1029, our long-acting antibody targeting MASP-2. In our MASP-2 small-molecule inhibitor program, we have selected a drug development candidate and are advancing to IND-enabling studies.
● OMS527 for the treatment of addiction — cocaine use disorder program funded by the National Institute on Drug Abuse ("NIDA")
o We are developing, at NIDA’s request, our lead orally administered phosphodiesterase 7 ("PDE7") inhibitor for the treatment of cocaine use disorder. Preclinical studies, designed with NIDA toxicologists, were completed and showed no drug-interaction or safety issues, supporting the scheduled in-patient human study of OMS527 in cocaine users.
o Following FDA’s request for additional nonclinical information and a subsequent meeting with FDA to discuss that request, we are working with FDA to streamline the path to initiate the in-patient clinical trial, targeted for initiation by year-end 2026.
● Oncology platform — OncotoX-AML
o We continue to progress preclinical studies within our novel oncology program. The lead indication for development is acute myeloid leukemia ("AML"), an aggressive and highly fatal bone marrow and blood cancer. We have completed selection of a drug development candidate in the OncotoX-AML program, and IND-enabling studies are underway.
o OncotoX-AML shows broad application across AML regardless of genetic mutation, including TP53, NPM1, KMT2A, and FLT3, collectively found in approximately 90% of AML patients. In human tumor-bearing animal and in vitro human AML cell-line studies, our AML therapeutic candidate has demonstrated superior efficacy to current AML standard of care treatments.
o In February 2026, we announced the successful completion of our initial study in nonhuman primates evaluating the efficacy and safety of OncotoX-AML. Administration of only one course of OncotoX-AML treatment to immunocompetent primates demonstrated the desired pharmacologic response, selectively reducing myeloid progenitor cells, which can mutate and lead to AML, by up to 99%. OncotoX-AML was well tolerated. There were no observed safety signals or meaningful changes in blood chemistry values.
● Targeted Complement Activating Therapy ("T-CAT") platform
o Our T-CAT platform is a new class of recombinant antibodies designed to target and directly kill pathogens, including bacteria, fungi, viruses, and parasites. Our initial focus is on multidrug-resistant organisms ("MDROs"), one of the most critical unmet needs in medicine.
o Data from our T-CAT platform were recently featured in a podium presentation at the annual congress of the European Society of Clinical Microbiology and Infectious Diseases.
o The seminal manuscript describing our T-CAT technology was accepted for publication in Science Translational Medicine.
Financial Results
Commercial distribution and sales of YARTEMLEA commenced in January 2026. Gross product sales for the three months ended March 31, 2026 were $11.1 million, with net sales of $9.9 million. Revenue for the period reflects sales of YARTEMLEA to U.S. wholesalers.
Net income for the first quarter of 2026 was $56.1 million, or $0.78 per share, compared to a net loss of $33.5 million, or $0.58 per share for the first quarter of 2025.
The change in fair value of financial instruments as shown in our statement of operations and comprehensive income (loss) reflects marking to market the embedded derivative on our 2029 Notes under GAAP. Excluding the net gain on the change in the fair value of our financial instruments, which is non-cash, our non-GAAP adjusted net loss for the three months ended March 31, 2026 was $17.1 million, or $0.24 per share.
At March 31, 2026, we had $135.3 million of cash and short-term investments. Upon their maturity in February 2026, we repaid the remaining $17.1 million outstanding principal balance of our 2026 Notes and currently have only $70.8 million aggregate principal amount outstanding of our 2029 Notes, which mature in June 2029.
Total operating expenses for the three months ended March 31, 2026 were $27.3 million compared to $35.0 million for the three months ended March 31, 2025. The $7.7 million decrease was primarily due to reduced OMS906-related research and development work as a result of the zaltenibart asset sale and licensing agreement with Novo Nordisk in November 2025.
Interest expense increased $2.2 million for the three months ended March 31, 2026 compared to the three months ended March 31, 2025. The increase primarily relates to interest incurred on the 2029 Notes and, to a lesser extent, a non-cash remeasurement charge taken on our OMIDRIA royalty obligation in the prior year, offset by decreased interest incurred on our 2026 Notes, which were repaid in February 2026.
Interest and other income was $1.5 million for the three months ended March 31, 2026 compared to $1.1 million for the three months ended March 31, 2025 due to holding higher cash and investment balances in the current period.
Net income from discontinued operations, net of tax, was $4.8 million, or $0.07 per share, for the three months ended March 31, 2026 compared to $4.1 million, or $0.07 per share, in the prior year period.
During the three months ended March 31, 2026, we repurchased and retired approximately 0.4 million shares of common stock pursuant to our share repurchase program, at an average cost of $11.70 per share, for an aggregate purchase price of $4.2 million.
