This 10-K filing reveals a pivotal year for Omeros, marked by two highly significant positive developments. The FDA approval of YARTEMLEA (narsoplimab-wuug) as the first and only approved therapy for TA-TMA is a transformational event, transitioning the company to a commercial stage with sales commencing in January 2026. Concurrently, the strategic partnership with Novo Nordisk, involving the sale of global rights to zaltenibart for a $240 million upfront payment and potential future milestones up to $1.8 billion, substantially strengthens Omeros's financial position and validates its MASP-3 program. These events collectively led to a dramatic reduction in net loss and improved liquidity, with the company now expecting to fund operations for over 12 months. The approval of a new $100 million share repurchase program further signals management's confidence in the company's future prospects and capital management strategy, even as it continues to utilize ATM and direct offerings for capital.
