Organization and Basis of Presentation
Organization and Basis of Presentation	Note 1—Organization and Basis of Presentation General Omeros Corporation (“Omeros,” the “Company” or “we”) is a clinical-stage biopharmaceutical company committed to discovering, developing and commercializing small-molecule and protein therapeutics for large-market as well as orphan indications targeting immunologic diseases, including complement-mediated diseases and cancers related to dysfunction of the immune system, as well as addictive and compulsive disorders. We marketed our first drug product, OMIDRIA^® (phenylephrine and ketorolac intraocular solution) 1% / 0.3% for use during cataract surgery or intraocular lens replacement in the United States (the “U.S.”) until we sold OMIDRIA and related business assets on December 23, 2021 (see “Sale of OMIDRIA Assets” below for additional information). Our drug candidate narsoplimab, targeting mannan-binding lectin-associated serine protease-2 (“MASP-2”) and the lectin pathway of complement, is the subject of a biologics license application (“BLA”) pending before the U.S. Food and Drug Administration (“FDA”) for the treatment of hematopoietic stem cell transplant-associated thrombotic microangiopathy (“HSCT-TMA”). On October 18, 2021, we announced the receipt of a Complete Response Letter (“CRL”) from FDA indicating that the BLA could not be approved as submitted. In November 2022, we received the decision by FDA’s Office of New Drugs (“OND”) denying our appeal of the CRL. Although our appeal was denied, the decision proposes a path forward for resubmission of the BLA based on survival data from the completed pivotal trial versus a historical control group, with or without an independent literature analysis. Clinical development of narsoplimab also includes programs focused on complement-mediated disorders, including immunoglobulin A (“IgA”) nephropathy, atypical hemolytic uremic syndrome (“aHUS”) and COVID-19. Our pipeline of investigational agents also includes: our long-acting MASP-2 inhibitor OMS1029, which is currently in a Phase 1 clinical trial, and OMS906, our inhibitor of mannan-binding lectin-associated serine protease 3 (“MASP-3”) targeting the alternative pathway of complement, which has completed a Phase 1 clinical trial and is being advanced into clinical programs for paroxysmal nocturnal hemoglobinuria (“PNH”) and complement 3 (“C3”) glomerulopathy. Basis of Presentation Our condensed consolidated financial statements include the financial position and results of operations of Omeros and our wholly owned subsidiaries. All inter-company transactions have been eliminated. The accompanying condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). Certain prior year amounts in the condensed consolidated balance sheets, statements of operations, statements of stockholders’ equity (deficit) and statements of cash flows and the notes to the condensed consolidated financial statements have been reclassified in the condensed consolidated financial statements to conform to the current year presentation. Sale of OMIDRIA Assets On December 23, 2021, we completed the sale of OMIDRIA and certain related assets and liabilities to Rayner Surgical Inc. (“Rayner”) pursuant to an Asset Purchase Agreement dated December 1, 2021 (the “Asset Purchase Agreement”). We received a payment of $126.0 million at closing and receive royalty payments on worldwide sales of OMIDRIA and potentially a $200.0 million milestone payment if separate payment for OMIDRIA is secured in the U.S. for a continuous period of at least four years before January 1, 2025. As a result of the divestiture, the results of OMIDRIA operations (e.g., revenues and operating costs) are included in discontinued operations in our condensed consolidated statements of operations and comprehensive loss for all periods presented (see “Note 3 – Discontinued Operations”). Risks and Uncertainties As of September 30, 2022, we had cash, cash equivalents and short-term investments of $221.0 million and outstanding accounts receivable of $13.9 million. Our loss for the quarter ended September 30, 2022 was $17.5 million. Included in our loss for the quarter was a $29.0 million noncash benefit related to the revaluation of our OMIDRIA contract royalty asset, which was partially offset by $4.6 million of noncash operating expenses. Our loss for the nine months ended September 30, 2022 was $81.3 million and included $30.5 million of noncash benefit related to the revaluation of our OMIDRIA contract royalty asset along with differences between actual and estimated royalties in the third quarter, which was partially offset by $12.5 million of noncash operating expenses. We plan to continue to fund our operations for the next twelve months with our existing cash and investments, our current accounts receivable, and our portion of OMIDRIA royalties. There is also the potential for us to receive a $200.0 million milestone related to achievement of long-term OMIDRIA separate payment if, prior to January 1, 2025, separate payment for OMIDRIA is secured under Medicare Part B for at least four continuous years. If FDA approval is granted for narsoplimab for HSCT-TMA, we expect that sales of narsoplimab will also provide funds for our operations. We have a sales agreement through which we may, from time to time, offer and sell shares of our common stock in an “at the market” equity offering for aggregate sales proceeds of up to $150.0 million. Should it be determined to be strategically advantageous, we could pursue debt financings as well as public and private offerings of our equity securities, similar to those we have previously completed, or other strategic transactions, which may include licensing a portion of our existing technology. Management believes the assets on hand along with our portion of expected OMIDRIA royalties to be received are adequate to finance our operations at least through November 9, 2023. Accordingly, the accompanying condensed consolidated financial statements have been prepared on a going-concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Significant items subject to such estimates include OMIDRIA contract royalty asset valuation, stock-based compensation expense, and accruals for clinical trials and manufacturing of drug product. We base our estimates on historical experience and on various other factors, including the impact of the COVID-19 pandemic, that we believe are reasonable under the circumstances; however, actual results could differ from these estimates.
