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 disorders including complement-mediated diseases, cancers, and 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). ​ The lead drug candidate in our pipeline of complement-targeted therapeutics is narsoplimab, a proprietary, patented human monoclonal antibody targeting mannan-binding lectin-associated serine protease 2 (“MASP-2”), the key activator of the lectin pathway of complement. Clinical development of narsoplimab is currently focused primarily on hematopoietic stem cell transplant-associated thrombotic microangiopathy (“HSCT-TMA”) and immunoglobulin A (“IgA”) nephropathy. Our pipeline of clinical-stage investigational agents also includes: our long-acting MASP-2 inhibitor, OMS1029, our inhibitor of mannan-binding lectin-associated serine protease-3 (“MASP-3”), OMS906, and our phophodiesterase 7 (“PDE7”) inhibitor, OMS527. Sale of OMIDRIA Assets On December 23, 2021, we closed on an Asset Purchase Agreement (the “Asset Purchase Agreement”) with Rayner Surgical Inc. (“Rayner”) for the sale of our commercial product OMIDRIA and certain related assets including inventory and prepaid expenses. Rayner paid us $126.0 million in cash at closing, and we retained all outstanding accounts receivable, accounts payable and accrued expenses as of the closing date. ​ Under the Asset Purchase Agreement, Omeros is entitled to receive a milestone payment of $200.0 million (the “Milestone Payment”) within 30 days following an event that establishes separate payment for OMIDRIA for a continuous period of at least four years when furnished in the ambulatory surgery center (“ASC”) setting. In December 2022, the milestone event occurred and we recorded a $200.0 million milestone receivable. We received the Milestone Payment together with accrued interest in February 2023. ​ As a result of the divestiture, the results of OMIDRIA operations (e.g., revenues and operating costs) have been reclassified to discontinued operations in our consolidated statements of operations and comprehensive income (loss) and excluded from continuing operations for all periods presented (See “Note 3 – Discontinued Operations”). ​ Basis of Presentation Our 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 consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). Liquidity and Capital Resources As of December 31, 2022, we had cash, cash equivalents and short-term investments of $194.9 million and outstanding accounts receivable of $213.2 million, substantially all of which have since been collected subsequent to year end. Our cash used in operations was $86.5 million and our net income for the year ended December 31, 2022 was $47.4 million, which included the $200.0 million Milestone Payment. In addition, the principal balance of $95.0 million outstanding on our 2023 convertible senior notes becomes due in November 2023. ​ Historically, we have incurred net losses from continuing operations and negative operating cash flows. We have not yet established an ongoing source of revenue sufficient to cover our operating costs and, therefore, could need to raise additional capital to accomplish our business plan and to retire our outstanding convertible senior notes due in 2026. We plan to continue to fund our operations for at least the next twelve months with our existing cash and investments and our accounts receivable. If FDA approval is granted for HSCT-TMA within the next twelve months, sales of narsoplimab may also provide funds for our operations. 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 aggregate amount 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. Segments We operate in one segment. Management uses cash flow as the primary measure to manage our business and does not segment our business for internal reporting or decision-making. 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 that we believe are reasonable under the circumstances; however, actual results could differ from these estimates.
