• We are an innovative, commercial-stage biotechnology company that discovers and develops first-in-class protein and small-molecule therapeutics for large-market and orphan indications, with particular emphasis on complement-mediated diseases, cancers, and addictive or compulsive disorders.

• The lead product and 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. Our lead lectin pathway inhibitor YARTEMLEA® (narsoplimab-wuu…

• Clinical development of narsoplimab is anticipated to continue expanding the approved label in TA-TMA and to develop the drug in additional indications. Clinical development efforts have previously been directed to acute respiratory distress syndrome (“ARDS”), including severe acute COVID-19, which …

• 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 hematopoiet…

• Commercial distribution and sales of YARTEMLEA began in January 2026. Both adult and pediatric patients with TA-TMA are now receiving YARTEMLEA, including patients who have recently failed prior off-label C5- and C3-inhibitor regimens, in both hospital and outpatient settings.

• 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. As previously disclosed, in March 2025, the Company resubmitted to the U.…

• In June 2025, we submitted a Marketing Authorization Application (“MAA”) for narsoplimab for the treatment of TA-TMA in the European Union. The European Medicines Agency (“EMA”) completed validation of the narsoplimab MAA, which confirms that the submission is accepted and starts the formal review p…

• As with any BLA or MAA, there can be no guarantee that FDA or the EMA will complete their respective reviews within a given timeframe, or that the Company’s BLA or MAA will ultimately be approved.

• Our pipeline also includes 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 a program focused on development of an orally administered small-molecule MASP-2 inhibitor. In the first …

However, interest is calculated based on adjusted SOFR, subject to a 3.00% floor, plus 8.75% per annum. Therefore, we experience exposure to any adjustments in the adjusted SOFR. Our Ter…

The share repurchase program does not have a fixed expiration date, may be suspen…

The existence of a share repurchase program could also cause our stock price to be higher than it would be in the absence of such a program and could potentially reduce the market liquidity…
