Commercial Product–* YARTEMLEA*
Current report
Our commercial product, YARTEMLEA, is the first and only approved inhibitor of the lectin pathway of complement. On December 23, 2025, FDA approved YARTEMLEA for the treatment of TA-TMA in adults and in children ages two years and older. TA-TMA is a severe and often-fatal complication of hematopoietic stem cell transplantation in adults and children, driven by systemic endothelial injury triggered by conditioning regimens, immunosuppressants, infection, graft-versus-host disease, and other transplant-related factors. Activation of the lectin pathway of complement plays a central role in disease pathogenesis. YARTEMLEA selectively inhibits MASP-2, blocking pathway activation while preserving classical and alternative complement functions important for host defense. In TA-TMA, MASP-2 inhibition prevents lectin pathway-mediated cellular injury, including endothelial damage in small blood vessels, and thrombus formation.
Current report
Commercial distribution and sales of YARTEMLEA commenced in January 2026.

Sale of Zaltenibart / MASP-3
Current report
On November 25, 2025, we completed the Transaction pursuant to our APLA with Novo Nordisk for our candidate drug zaltenibart (formerly OMS906). Zaltenibart is a first-in-class, late-stage clinical humanized monoclonal antibody targeting MASP-3, the most upstream and key activator of the alternative pathway of the complement system. Zaltenibart has shown multiple potential advantages over other alternative pathway inhibitors in development and on the market.
Current report
At the closing of the Transaction, we received an upfront cash payment of $240.0 million. In addition, we are eligible to receive (i) up to $510.0 million in one-time milestone payments upon the first achievement by Novo Nordisk or its affiliates or sublicensees of each of the development and approval milestone events as set forth in the APLA and (ii) up to $1.3 billion in one-time milestone payments upon the first achievement by Novo Nordisk or its affiliates or sublicensees of certain sales-based milestone events as set forth in the APLA. We are also eligible under the APLA to receive tiered royalties on annual net sales of products at percentage rates ranging from high single digit to high teens, subject to reduction in certain circumstances, as set forth in the APLA. In total, we are eligible to receive up to an additional $1.8 billion in potential development and commercial milestones, plus tiered royalties on net sales.
Current report
Pursuant to the APLA, we sold and transferred, and Novo Nordisk purchased zaltenibart and certain related assets, and the parties agreed to grant and receive certain intellectual property licenses to facilitate the continued development and commercialization activities of both companies. We retain rights to our MASP-3 small-molecule program unrelated to zaltenibart, including the ability to develop and commercialize small-molecule MASP-3 inhibitors, across a range of therapeutic areas, including, but not limited to, ophthalmology, neurology, gastrointestinal disorders, dermatology, musculoskeletal diseases, and oncology. We also retain rights to our “grandfathered” MASP-3 antibodies, with temporal and indication restrictions on commercialization and for use in advancing our small-molecule therapeutics.
Current report
In accordance with the APLA, at the closing of the Transaction, Omeros and Novo Nordisk entered into the Transition Services Agreement pursuant to which we are providing certain transition services to Novo Nordisk to facilitate the transfer of the acquired assets and liabilities under the APLA and to provide for the continued operation of relevant studies and program activities during the applicable term. Subject to certain exceptions and limitations, Novo Nordisk reimburses us for costs and expenses we incur under the Transition Services Agreement, including third-party costs and expenses, costs associated with delivery of transition services by Omeros personnel on an hourly basis at rates specified in the Transition Services Agreement, and for our inventories of zaltenibart drug substance and product.

Preclinical Programs - OncotoX-AML
Current report
We continue to progress preclinical studies within our novel oncology program, which is focused on developing novel, proprietary large molecule therapeutics designed to selectively target and kill dividing cancer cells. We have completed selection of a drug development candidate, and IND-enabling studies are underway for this program, which we refer to as OncotoX-AML. AML, an aggressive and highly fatal bone marrow and blood cancer, is the lead indication for development. The effectiveness of current AML treatments, such as chemotherapeutics and antibody-drug conjugates, is limited by a number of factors, including high relapse rates and substantial side effects.
Current report
OncotoX-AML is an engineered biologic designed to selectively kill both AML blasts (abnormal myeloid cells) and relapse-related leukemia stem cells. Its unique mechanism of action is independent of myeloid cell genetic mutations, including TP53, NPM1, KMT2A, and FLT3, which are collectively found in approximately 90% of AML patients and are historically difficult to treat. For more information, see Part I, Item 1 in this Annual Report on Form 10-K under the heading “Other Development Programs: OncotoX-AML”.
Current report
Preclinical Programs - T-CAT
Current report
We are also advancing our T-CAT platform: a new class of recombinant antibodies intended for broad action against bacteria, fungi, viruses, and parasites. T-CAT is designed to harness complement activation to kill pathogens directly, which represents a novel approach to infectious disease treatment.
Current report
As preclinical animal data continue to accumulate across multiple pathogen classes and species, we believe that T-CAT demonstrates potential against MDROs. Effective MDRO therapies remain one of the most urgent and unmet needs in medicine, and we believe that T-CAT has the potential to address this need without contributing to drug resistance. For more information, see Part I, Item 1 in this Annual Report on Form 10-K under the heading “Other Development Programs:T-CAT - Infectious Disease”.

OMIDRIA Sale and Royalty Monetization Transactions
Current report
On December 23, 2021, we sold OMIDRIA to Rayner pursuant to an Asset Purchase Agreement, dated December 1, 2021 (the “Asset Purchase Agreement”). In February 2023, we received a $200.0 million milestone payment from Rayner (the “Milestone Payment”), plus accrued interest, upon an event (the “Milestone Event”) that established separate payment for OMIDRIA for a continuous period of at least four years when furnished in an ambulatory surgery center (“ASC”) setting. The Asset Purchase Agreement also provides for the payment of royalties by Rayner based on Rayner's net sales of OMIDRIA for a term that extends for the life of the patents covering OMIDRIA in the relevant jurisdiction, the longest of which in the United States is currently into 2035. The applicable royalty rates are currently 30% in the United States and 15% outside the United States (“ex-U.S.”), subject to reduction upon certain events described in the Asset Purchase Agreement.

Exchange of 2026 Notes for Term Loan and Cash
Current report
On June 3, 2024, we, with certain subsidiaries, as guarantors, entered into a Credit and Guaranty Agreement (the “Credit Agreement”) with certain funds managed by Athyrium Capital Management, LP and certain funds managed by Highbridge Capital Management, LLC, as lenders (together with additional lenders from time to time, the “Lenders”) and Wilmington Savings Fund Society, FSB, as administrative agent and collateral agent. Along with borrowings of $67.1 million under the Credit Agreement (the “Term Loan”) and $21.7 million of cash on hand (for a total aggregate purchase price of $88.8 million), we repurchased from the lenders $118.1 million aggregate principal amount of our 2026 Notes. The $29.3 million difference between the $118.1 million aggregate principal amount of the 2026 Notes and the $88.8 million aggregate repurchase price was recorded as a premium (i.e., an increase) to the Term Loan on the Company’s consolidated balance sheet instead of being recognized as a gain on early extinguishment of debt as this was accounted for as a troubled debt restructuring.
Current report
Exchange of 2026 Notes for 2029 Notes and Equitization Transaction
Current report
On May 14, 2025, we completed the exchange (the “Convertible Note Exchange”) of $70.8 million of our 2026 Notes on a one-for-one basis for newly-issued 2029 Notes. The Convertible Note Exchange was conducted with a limited number of holders of the 2026 Notes pursuant to exchange agreements dated as of May 12, 2025. The 2029 Notes are convertible at the option of the holders into shares of common stock, cash or a combination thereof, as elected by the Company, at any time prior to the close of business on the second scheduled trading day immediately preceding the maturity date. Holders who convert their 2029 Notes after November 13, 2025 and prior to June 1, 2029 (except for any conversion in connection with a make-whole fundamental change) are entitled to an interest make-whole payment equal to the sum of the remaining scheduled payments of interest that would have been made had the 2029 Notes remained outstanding from their conversion date through the earlier of (i) the date that is 18 months following their conversion date, and (ii) June 15, 2029, the maturity date. The initial conversion rate for the 2029 Notes is equivalent to an initial conversion price of approximately $6.18 per share of our common stock. The conversion rate is subject to adjustment in certain circumstances.
Current report
The 2029 Notes include both a derivative for the interest make-whole feature and a derivative for the conversion feature available to holders allowing them to convert their notes to common stock, cash or a combination thereof. At each reporting date, we remeasure the embedded derivative instruments to fair market value. Increases or decreases in our stock price may materially affect the fair value of the derivative. The remeasurement of the derivative is presented in our consolidated statement of operations and comprehensive loss. At contract inception, we recorded a net $23.0 million embedded derivative as a component of our 2029 Notes. However, with the sale of OMS906 to Novo Nordisk and the announcement of FDA approval of TA-TMA, our stock price significantly increased. At December 31, 2025, the fair market value of our embedded derivative was $157.2 million. We marked-to-market the initial $23.0 million embedded derivative on the 2029 Notes and recorded a $134.2 million non-cash loss on remeasurement to our consolidated statement of operations and comprehensive loss.
Current report
On May 12, 2025, we entered into the note conversion agreements (each, a “Note Conversion Agreement”) with two holders of the 2026 Notes to convert $10.0 million aggregate principal amount of 2026 Notes into shares of our common stock in three tranches. We completed the conversion of the final tranche in September 2025, resulting in the issuance of an aggregate of 2,819,866 shares of our common stock to the two holders in exchange for the $10.0 million aggregate principal amount of 2026 Notes. We did not receive new cash proceeds in these transactions. We performed an assessment of the Convertible Note Exchange and Equitization Transaction and determined that these transactions were not a troubled debt restructuring and were a partial extinguishment of our 2026 Notes.
Current report
These transactions resulted in a net $3.0 million non-cash loss on extinguishment of the 2026 Notes due to (1) expensing of the unamortized debt issuance costs of the extinguished 2026 Notes, (2) recording the 2029 Notes to fair market value (i.e., at a discount) which we recorded both to our statement of operations and comprehensive loss and as debt on our balance sheet and (3) recording the fair market value of the share-settled liability upon settlement.
Current report
Repayment of Term Loan
Current report
On November 25, 2025, concurrent with the closing of the sale and licensing of zaltenibart (OMS906) to Novo Nordisk under the APLA, we were required under the terms of the Credit Agreement to repay in full the $67.1 million principal outstanding under the Term Loan along with a 5% prepayment premium. We recognized a net non-cash gain on extinguishment in the amount of $17.0 million which represents the de-recognition of $17.9 million in unamortized premium and debt issuance costs, derecognition of $2.6 million of embedded derivatives, partially offset by $3.5 million of prepayment premium and related transaction expenses.
Current report
Repayment of our obligations under the Credit Agreement resulted in the release in full of all liens and covenants thereunder including the covenant requiring us to maintain a minimum of $25.0 million in unrestricted cash, cash equivalents and short-term investments at all times.
Current report
Repayment at Maturity of Remaining 2026 Notes
Current report
On February 17, 2026, we repaid the remaining $17.1 million aggregate principal amount of outstanding 2026 Notes in full upon maturity.

At the Market Sales Agreement
Current report
We have a sales agreement to sell shares of our common stock from time to time, through an “at the market” (“ATM”) equity offering program. During the year ended December 31, 2025, we sold 4.4 million shares of common stock pursuant to our ATM program, generating $19.0 million in net proceeds at an average price per share of $4.51. On November 14, 2025, the Company filed a shelf registration statement and prospectus supplement renewing the ATM program for an aggregate offering price up to $150.0 million, and as of the date of this annual report, we have $150.0 million in shares of our common stock available to sell under our ATM program.
Current report
Registered Direct Offering
Current report
On July 28, 2025, we issued and sold 5,365,853 shares of our common stock in a registered direct offering to entities managed by Polar Asset Management Partners at a price of $4.10 per share, representing a 14% premium to the closing price of our common stock on the date of the definitive agreement for the purchase of shares. We received $20.3 million in cash proceeds net of offering expenses.

Alternative Pathway / MASP-3
Previous report
Our pipeline of clinical-stage complement-targeted therapeutic candidates also includes zaltenibart (OMS906), a proprietary, patented monoclonal antibody targeting MASP-3, the key activator of the alternative pathway of complement. We believe zaltenibart has the potential to treat a wide range of alternative pathway-related diseases and that its attributes favorably differentiate zaltenibart from other marketed and in-development alternative pathway inhibitors.
Previous report
Clinical development of zaltenibart is currently focused on PNH and C3G. We have initiated our Phase 3 clinical development program for zaltenibart in PNH and have an ongoing Phase 2 clinical trial evaluating zaltenibart in C3G. For more information, see Part I, Item 1 in this Annual Report on Form 10-K under the heading “Complement Inhibitor Programs:MASP-3 Program –Alternative Pathway Disorders”.

Preclinical Programs - Oncology Platform
Previous report
We are developing a portfolio of signaling-driven immunomodulators, oncotoxins, and an adoptive T-cell technology combined with an immunostimulator that, unlike other cellular therapy approaches requires no cellular engineering, may reduce manufacturing costs and timelines, and may maintain an enhanced anti-cancer immune response through subsequent repetitive and simple therapeutic administrations.
Previous report
Our oncology development program is operating in stealth mode as we continue to confirm our results and to generate new data which we expect will contribute to our intellectual property position. For more information, see Part I, Item 1 in this Annual Report on Form 10-K under the heading “Preclinical Programs and Platforms:Oncology Platform”.
Previous report
On December 23, 2021, we sold our commercial product, OMIDRIA, to Rayner. Rayner paid us $126.0 million at the closing and we retained all outstanding accounts receivable, accounts payable and accrued expenses as of the closing date.

Payment on Maturity of 2023 Notes
Previous report
On June 3, 2024 (the “Closing Date”), we, with certain subsidiaries, as guarantors, entered into the Credit Agreement with Athyrium and Highbridge as lenders (together with additional lenders from time to time, the “Lenders”) and Wilmington Savings Fund Society, FSB, as administrative agent and collateral agent. The Credit Agreement provides for a senior secured term loan facility initially of up to $92.1 million consisting of (i) the Initial Term Loan of $67.1 million, which was fully funded on the Closing Date, and (ii) a $25.0 million Delayed Draw Term Loan, which may be drawn once in full upon notice delivered on or prior to June 3, 2025, conditioned on receipt of FDA approval of narsoplimab in TA-TMA within 30 days of the notice. We do not expect that FDA approval of narsoplimab will be obtained within a timeframe that would permit the Delayed Draw Term Loan to be drawn absent an amendment to, or waiver of, this condition. Proceeds of the Delayed Draw Term Loan, if borrowed, must be used to fund the commercialization of narsoplimab and to pay transaction costs associated with the Delayed Draw Term Loan. The Initial Term Loan has no original issue discount, while the Delayed Draw Term Loan, if drawn, would be issued with an original issue discount of 3.00%.
Previous report
In 2024, we used the $67.1 million Initial Term Loan, along with $21.7 million of cash on hand to repurchase from the Lenders $118.1 million aggregate principal amount of the 2026 Notes (the “2026 Note Repurchase Transaction”). The principal amount retired in the 2026 Note Repurchase Transaction represented a 55% reduction of the outstanding principal balance of the 2026 Notes at a purchase price of approximately 75% of par value.
Previous report
We are permitted under the Credit Agreement to repurchase additional outstanding 2026 Notes for cash in open market or privately negotiated transactions, subject to certain limitations described below. Additionally, until the earlier of November 1, 2025 and the date the we elect to draw under the Delayed Draw Term Loan, we, at our sole discretion, may exchange up to $14.9 million aggregate principal amount of outstanding 2026 Notes for cash and additional term loan amounts, with the holders of such notes becoming Lenders under the Credit Agreement (any such additional term loans, together with the Initial Term Loan and the Delayed Draw Term Loan, the “Loans”). We also retain all potential future value of the capped call purchased in connection with the issuance of the 2026 Notes covering all shares underlying the original 2026 Notes.
Previous report
All indebtedness outstanding under the Credit Agreement is guaranteed by certain of our direct and indirect subsidiaries, other than certain foreign subsidiaries that are not material (we and the guarantors, collectively, the “Credit Parties”). Pursuant to a Pledge and Security Agreement, dated June 3, 2024, the indebtedness under the Credit Agreement is secured by a first-priority security interest in and lien on substantially all tangible and intangible property of the Credit Parties, subject to customary exceptions, and excluding royalty interests in OMIDRIA and certain related rights.
Previous report
The Credit Agreement contains certain customary default provisions, representations and warranties and affirmative and negative covenants, including a covenant for the Credit Parties to maintain at all times unrestricted cash, cash equivalents and short-term investments of at least $25.0 million in accounts subject to control agreements, and a covenant limiting the use of cash for open market or privately negotiated repurchases of any outstanding 2026 Notes to: (i) an initial amount not exceeding $25.0 million, which may be increased by up to an additional $10.0 million subject to the satisfaction of certain conditions; (ii) an unlimited amount, if the amount of Loans outstanding at the time of repurchase does not exceed $38.5 million; and (iii) an additional amount not to exceed 50% of the net cash proceeds from an equity offering, provided that we offer to prepay an equal amount of Loans with the net cash proceeds of such offering.
Previous report
The Loans accrue interest at an adjusted term secured overnight financing rate, (“adjusted term SOFR”) (with a 3.00% floor) plus 8.75% per annum, payable quarterly. We may choose to pay up to 50% of any quarterly interest payment in kind by adding the portion of such interest payment to the outstanding principal amount of Loans using a quarterly interest rate of adjusted term SOFR (with a 3.00% floor) plus 10.25% per annum. A default interest rate of an additional 3.00% per annum would apply on all outstanding obligations after the occurrence and during the continuance of certain specified events of default.
Previous report
The Credit Agreement with a four-year term has a scheduled maturity date of June 3, 2028 (unless all Loans become due and payable at an earlier date, whether by acceleration or otherwise). If on November 1, 2025, (i) the aggregate principal amount of the 2026 Notes outstanding that is not held by the Lenders is equal to or greater than $38.5 million and (ii) we have not made nor delivered notice that we expect to make certain voluntary or mandatory prepayments under the Credit Agreement of at least $20.0 million in the aggregate, then we would be required to prepay the Loans in the amount necessary to achieve the $20.0 million prepayment requirement. We expect to prepay the $20.0 million in November 2025 along with a $1.0 million prepayment penalty and have reflected this consideration in our consolidated balance sheet. All mandatory prepayments are subject to the prepayment premiums as described below.
Previous report
We may elect to prepay Loans, in whole or in part, in cash, subject to (i) during the first year of such Loans, a make-whole premium plus 5.00% of the aggregate principal amount of Loans subject to prepayment (unless the prepayment is made in contemplation of a change of control, in which case only the make-whole premium would be payable); (ii) during the second year, a 5.00% prepayment premium; and (iii) during the third year, a 3.00% prepayment premium. The Credit Agreement requires mandatory prepayments of Loans in an amount equal to 60% of the net cash proceeds (excluding research and development and certain other milestone payments) received by the Credit Parties from asset sales and licenses, provided that if an asset sale or license involving narsoplimab occurs while any Delayed Draw Term Loans are outstanding, mandatory prepayments must be in an amount equal to 100% of the net cash proceeds from such sale. Mandatory prepayments are also required: (i) from insurance recoveries on loss of property that are not otherwise reinvested in other assets of the Credit Parties; (ii) from indebtedness incurred by any of the Credit Parties other than as permitted by the Credit Agreement; (iii) in the event of a change of control and (iv) in respect of 25% of the amount of any Milestone Payment received from DRI its affiliates on the basis of net sales of OMIDRIA.
Previous report
As of December 31, 2024, we had cash, cash equivalents and short-term investments of $90.1 million available to fund operations and to service debt.
Previous report
Clinical research and development expenses increased $4.8 million between 2023 and 2022. The $16.5 million increase in OMS906 development costs was due to an increase in manufacturing and Phase 2 clinical trial costs and a $5.0 million development milestone paid in 2023 under a technology license agreement. The $3.6 million increase in OMS1029 expense was primarily due to costs associated with initiation of human trials and other clinical development costs in the transition from preclinical to clinical development status in the third quarter of 2022. These increases were offset by decreased narsoplimab manufacturing costs during 2023.
Previous report
Our selling, general and administrative expenses are expected to be higher than in 2024. The magnitude of the anticipated increase in selling, general and administrative expenses for 2025 will be highly dependent on whether narsoplimab receives U.S. regulatory approval for treatment of TA-TMA. If narsoplimab is approved in 2025, we expect to hire a field sales force and initiate commercial launch activities which will increase our selling, general and administrative expenses.
Previous report
Interest expense increased $8.1 million in 2023 compared to 2022 primarily due to interest incurred from our OMIDRIA royalty obligation.
Previous report
Interest and other income principally includes $8.4 million of interest earned on our investments, $1.6 million earned on sublease rental income and $1.3 million of NIDA grant income. The $5.0 million decrease in interest and other income between 2024 and 2023 was primarily due to holding lower average cash and investment balances than in the prior year. The $12.3 million increase in interest and other income between 2023 and 2022 was a result of receiving the $200.0 million Milestone Payment from Rayner in February 2023 and investing those funds.
Previous report
Gain on Early Extinguishment of Convertible Senior Notes
Previous report
As of December 31, 2024, we had cash, cash equivalents and short-term investments of $90.1 million. Our cash used in operations for the year ended December 31, 2024 was $148.8 million and included a net loss for the year of $156.8 million. Pursuant to a covenant in the Credit Agreement, we must maintain $25.0 million of unrestricted cash, cash equivalents and short-term investments at all times.
Previous report
In recent years, we have incurred net losses from continuing operations and negative cash flows from operations. The recurring losses, in combination with our cash and investment balances as of December 31, 2024, expected repayment of a portion of the borrowings under our secured credit facility on or prior to November 1, 2025 and maturity of our 2026 Notes on February 15, 2026, raise substantial doubt about our ability to continue as a going concern through one year from the issuance of the Company's consolidated financial statements. As we currently do not have an ongoing source of revenue sufficient to cover our operating costs, we will need to raise additional capital to accomplish our business plan. We have a sales agreement to sell shares of our common stock, from time to time, in an “at the market” equity offering facility through which we may offer and sell shares of our common stock equaling an amount up to $150.0 million. Our Delayed Draw Term Loan of $25.0 million may be drawn once in full upon notice delivered on or prior to June 3, 2025, conditioned on receipt of FDA approval of narsoplimab in TA-TMA within 30 days of the notice; however, we do not expect that FDA approval of narsoplimab will be obtained within the timeframe that would permit us to draw the Delayed Draw Term Loan absent an amendment to, or a waiver of, this condition. Proceeds of the Delayed Draw Term Loan, if available, may only be used towards any related transaction costs and for commercialization of narsoplimab efforts of TA-TMA.
Previous report
If these capital resources, for any reason, are needed but inaccessible, it would have a significant negative impact on our financial condition. For purposes of determining available capital resources, potential future royalty and/or milestone receipts are excluded. Should it be necessary, we plan to manage our operating expenses and reduce our projected cash requirements by delaying clinical trials, reducing selected research and development efforts, or implementing other restructuring activities.
Previous report
Net cash provided by operating activities for the year ended December 31, 2023 increased by $161.2 million compared to the same period in 2022. This increase was primarily due to collecting the $200.0 million Milestone Payment from Rayner in February 2023 and a $15.3 million increase in accounts payable and accrued expenses in 2023. This increase was partially offset by a $26.7 million change in the remeasurement of the OMIDRIA contract royalty asset, $8.7 million related to the accretion of interest on U.S. government treasury bills and a $4.1 million gain on the early extinguishment of a portion of our 2026 Notes.
Previous report
Net cash provided by investing activities increased $155.0 million during 2023 compared to 2022 driven by collection of the $200.0 million Milestone Payment from Rayner we received in February 2023.
Previous report
Net cash used in financing activities decreased $230.3 million during 2023 compared to the prior year. The decrease was primarily due to receiving $125.0 million in 2022 in connection with selling a portion of our OMIDRIA royalties to DRI and extinguishing $95.0 million of our 2023 Notes. In addition, we paid $4.9 million to retire $9.1 million par value of our 2026 Notes and repurchased $4.7 million of our common stock through a stock repurchase program in 2023.

Previous wording
The lead product candidate in our pipeline of complement-targeted therapeutics is narsoplimab (OMS721), a proprietary, patented human monoclonal antibody targeting MASP-2, the key activator of the lectin pathway of complement. Clinical development of narsoplimab is currently focused primarily on TA-TMA and development efforts are also directed to COVID-19, ARDS and PASC. We are also developing OMS1029, our long-acting antibody targeting MASP-2 which we expect will be well-suited to indications requiring long-term, chronic administration. In addition, we are advancing our orally administered small-molecule MASP-2 inhibitor through IND-enabling studies. For more information, see Part I, Item 1 in this Annual Report on Form 10-K under the heading “Complement Inhibitor Programs:MASP-2 Program –Lectin Pathway Disorders”.

Our lead lectin pathway inhibitor YARTEMLEA® (narsoplimab-wuug) is FDA-approved and commercially available in the U.S. for the treatment of TA-TMA in adult and pediatric patients aged two years and older. An MAA for YARTEMLEA in TA-TMA is currently under review by the EMA. Clinical development of narsoplimab is anticipated to continue to expand the approved label in TA-TMA and to develop the drug in additional indications. Clinical development efforts have previously been directed to ARDS, including severe acute COVID-19, which can result in PASC. We are also developing OMS1029, our long-acting antibody targeting MASP-2, which we expect will be well-suited to indications requiring long-term, chronic administration. In addition, we have directed efforts towards the development of small-molecule inhibitors of MASP-2, designed for oral administration. For more information, see Part I, Item 1 in this Annual Report on Form 10-K under the heading “Complement Inhibitor Programs:MASP-2 Program –Lectin Pathway Disorders”.

Our PDE7 inhibitor program, which we refer to as OMS527, comprises multiple PDE7 inhibitor compounds and is based on our discoveries of previously unknown links between PDE7 and any addiction or compulsive disorder, and between PDE7 and any movement disorders. In April 2023, we were awarded a grant from the National Institute on Drug Abuse, part of the National Institutes of Health, to develop our lead orally administered PDE7 inhibitor compound, for which we have successfully completed a Phase 1 study, for the treatment of cocaine use disorder (“CUD”). With NIDA funding, we successfully completed preclinical cocaine interaction/toxicology studies to assess safety of the OMS527 compound when co-administered with cocaine. Based on the successful outcome of the preclinical studies, we have initiated, and NIDA has confirmed availability of grant funding for, an in-patient, placebo-controlled clinical study evaluating the safety and effectiveness of OMS527 in adults with CUD who receive concurrent intravenous cocaine. For more information, see Part I, Item 1 in this Annual Report on Form 10-K under the heading “Other Clinical Programs:PDE7 Inhibitor Programs–* OMS527*”.

On February 1, 2024, we sold an expanded interest in our future OMIDRIA royalties to DRI and received $115.5 million in cash consideration, which we recorded as an addition to the OMIDRIA royalty obligation. The amended and restated royalty purchase agreement with DRI (the “Amendment”) eliminated the previously existing annual caps on royalty payments after January 1, 2024, and provides that DRI receives all royalties on U.S. net sales of OMIDRIA payable between January 1, 2024 and December 31, 2031. In addition to the cash consideration received at closing, the Amendment also entitles us to receive two milestone payments of up to $27.5 million each, payable in January 2026 and January 2028, respectively, based on achievement of certain thresholds for U.S. net sales of OMIDRIA. All royalties earned on OMIDRIA sales within the U.S. through December 31, 2031 are remitted by Rayner to an escrow account established by Omeros, from which payments are made to DRI. We retain the rights to receive all royalties payable by Rayner on any net sales of OMIDRIA outside the U.S. as well as royalties on global net sales of OMIDRIA payable from and after December 31, 2031, including royalties on U.S. OMIDRIA net sales. To date, international royalties have not been significant. DRI has no recourse to our assets other than its interest in OMIDRIA royalties. Interest expense on the OMIDRIA royalty obligation is recorded as a component of continuing operations. See Part II, Item 8, “Note 8 – OMIDRIA Royalty Obligation” to our Consolidated Financial Statements in this Annual Report on Form 10-K for additional information.

Our research and development expenses can be divided into three categories: direct external expenses, which include clinical research and development and preclinical research and development activities; internal overhead and other expenses; and stock-based compensation expense. Direct external expenses consist primarily of expenses incurred pursuant to agreements with third-party manufacturing organizations prior to receiving regulatory approval for a product candidate, CROs, clinical trial sites, collaborators, licensors and consultants. Preclinical research and development includes costs prior to beginning Phase 1 studies in human subjects. Internal overhead and other expenses primarily consist of costs for personnel, overhead, rent, utilities and depreciation. Our accounting policy is to expense all manufacturing costs related to product candidates until regulatory approval is reasonably assured in either the U.S. or European Union.

Clinical research and development expenses increased $0.5 million between 2024 and 2023. The change primarily relates to $16.1 million of TA-TMA drug manufacturing costs in anticipation of our BLA and $2.1 million in zaltenibart clinical trials expense and associated costs to manufacture drug supply. These costs are partially offset by a $15.5 million reduction in IgA nephropathy expenses with the closing out of the program and a $2.2 million reduction in OMS1029 expenses primarily due to the completion of one of our single ascending dose studies.

Previous wording
Preclinical research and development expenses increased $1.3 million in 2024 compared to 2023, primarily due to increased preclinical oncology research and cocaine addiction work during 2024. The cocaine addiction work is being funded by a grant from NIDA, with associated grant revenue included in other income. The $2.1 million decrease in 2023 over 2022 in preclinical research and development expenses was primarily due to the migration of OMS1029 from preclinical to clinical research and development status during the third quarter of 2022, offset by an increase in preclinical oncology work during 2023.

We expect our overall research and development costs in 2025 to be slightly higher than in 2024, driven by increases in zaltenibart clinical trial costs associated with Phase 3 trials in PNH and C3G, a milestone payment under an existing licensing agreement, and drug manufacturing costs, which we expect to be partially offset by decreases in narsoplimab drug manufacturing and clinical trial costs. Our accounting policy is to expense all manufacturing costs related to product candidates until regulatory approval is reasonably assured in either the U.S. or Europe.
Current wording
We expect our overall research and development costs in 2026 to be lower than in 2025. This anticipated decrease is primarily attributable to reduced clinical trial costs for zaltenibart as these program costs will be incurred by Novo Nordisk in connection with the APLA and the Transition Services Agreement, the absence of development milestone payments under our existing licensing agreement related to zaltenibart, and reduced spend on overall drug manufacturing. Our accounting policy is to expense all manufacturing costs related to product candidates until regulatory approval is reasonably assured in either the U.S. or Europe.

We have rights to receive future royalties from Rayner on OMIDRIA net sales at royalty rates that vary based on geography and certain regulatory contingencies. Therefore, future OMIDRIA royalties are treated as variable consideration. To measure the OMIDRIA contract royalty asset, we used the expected value approach which is the discounted sum of probability-weighted royalty payments we would receive using a range of potential outcomes, to the extent that it is probable that a significant reversal in the amount of cumulative income recognized will not occur. Our calculations take the net present value of the sum to arrive at the OMIDRIA contract royalty asset stated on the balance sheet. We revalued the contract royalty asset to reduce the applicable royalty percentage from 50% to 30%, as required under the Asset Purchase Agreement following the occurrence of the Milestone Event triggering the $200.0 million Milestone Payment in 2022. Royalties earned will be recorded as a reduction to the OMIDRIA contract royalty asset. The amount recorded in discontinued operations in future periods will reflect interest earned on the outstanding OMIDRIA contract royalty asset and any amounts received different from the expected royalties recorded at closing. The OMIDRIA contract royalty asset is subject to changes in net sales of OMIDRIA. All else being equal, a 10% decrease or increase in net sales results in a $15.3 million change in value of the OMIDRIA contract royalty asset, resulting in a potential OMIDRIA contract royalty asset valued within the range of $138.0 million to $168.7 million. Changes in net sales could occur due to various risks such as competitors entering the market, changes in the standard of care for cataract patients and loss of separate payment status for OMIDRIA. In determining the value of the OMIDRIA contract royalty asset, we have considered all of these factors. The OMIDRIA contract royalty asset will be re-measured periodically using the expected value approach based on actual results and future expectations. Any required adjustment to the OMIDRIA contract royalty asset will be recorded in discontinued operations.

We currently earn a royalty rate of 15% on net ex-U.S. sales. Royalties earned are recorded as a reduction to the OMIDRIA contract royalty asset.
Previous wording
To the extent our estimates of future royalties are less than previous estimates, we will adjust the carrying amount of the royalty obligation to the present value of the revised estimated cash flows, discounted at the original effective interest rate utilizing the cumulative catch-up method. The adjustment would be recognized as a component of net income (loss) from continuing operations. Our estimate of cash flows from future royalties is derived from the contract royalty asset accounting described above.
Current wording
To the extent our estimates of future royalties are less than previous estimates, we will adjust the carrying amount of the royalty obligation to the present value of the revised estimated cash flows, discounted at the original effective interest rate utilizing the cumulative catch-up method. Any remeasurement adjustment is recognized as a component of interest expense in net loss from continuing operations. Our estimate of cash flows from future royalties is derived from the contract royalty asset accounting described above.
Previous wording
Transactions involving contemporaneous exchanges of cash between the same debtor and creditor in connection with the issuance of a new debt obligation and satisfaction of an existing debt obligation by the debtor are first evaluated as to whether they qualify as a troubled debt restructuring (“TDR”) under ASC Topic 470-60,Debt - Troubled Debt Restructuring by Debtors (“ASC 470-60”). ASC 470-60 requires debt modifications to be evaluated if (1) the borrower is experiencing financial difficulty, and (2) the lender grants the borrower a concession. If both conditions are met under TDR accounting, we would record as the carrying value of the new debt any repurchased old debt less any cash paid. No gain on restructuring is recognized unless the carrying value of the new debt exceeds the undiscounted cash flows of the new debt. Any cancellation of debt income is amortized over the term of the new debt. We determined that the Initial Term Loan qualified as a TDR. Therefore, we amortized as debt premium the cancellation of debt income from the partial repurchase of the 2026 Notes against the Initial Term Loan. If a TDR is determined to not have occurred, we evaluate the modification in accordance with ASC Topic 470-50-40,Debt - Modifications and Extinguishments, which requires modification of debt instruments to be evaluated to assess whether the modifications are considered “substantial”. In instances where our future cash flows change more than 10%, we record our debt at fair value based on factors available to us for similar borrowings and use the extinguishment accounting method. We extinguished the 2023 Notes at maturity. The partial repurchase of the 2026 Notes in 2023 was deemed to be a modification whereby we were able to recognize a $4.1 million gain on debt extinguishment.

DRI has no recourse to our assets other than its interest in OMIDRIA royalties. Interest expense on the OMIDRIA royalty obligation is recorded as a component of continuing operations. See Part II, Item 8, “Note 9 – OMIDRIA Royalty Obligation” to our Consolidated Financial Statements in this Annual Report on Form 10-K for additional information.

Contractual interest expense is comprised of cash interest paid during the year and the net change in accrued interest. Amortization of debt discounts, premiums and issuance costs are reflected as non-cash interest expense. Debt discounts on the 2026 Notes and 2029 Notes are accretive whereas the premium on the Term Loan is deducted from contractual interest expense.

The OMIDRIA contract royalty asset is subject to changes in net sales of OMIDRIA. All else being equal, a 10% decrease or increase in net sales results in a $12.2 million change in value of the OMIDRIA contract royalty asset, resulting in a potential OMIDRIA contract royalty asset valued within the range of $109.6 million to $134.0 million. Changes in net sales could occur due to various risks such as competitors entering the market, changes in the standard of care for cataract patients and loss of separate payment status for OMIDRIA. In determining the value of the OMIDRIA contract royalty asset, we have considered all of these factors. The OMIDRIA contract royalty asset is remeasured periodically using the expected value approach based on actual results and future expectations. The royalties earned and any remeasurement adjustments are recorded in discontinued operations.
