This 10-Q provides the detailed financial results for Q1 2026, confirming the negative trends highlighted in the concurrent 8-K. The company's net loss widened significantly to $128.9 million from $48.4 million in the prior year, driven by a sharp decline in collaboration and royalty revenue and a substantial $51.9 million unrealized loss on its equity investment in Zenas BioPharma. A key negative development is Alexion's dispute over U.S. Ultomiris royalties, leading to a $6.6 million reduction in recognized revenue and creating uncertainty around a significant future revenue stream. While the company maintains a cash runway into 2028 and reported positive clinical progress for some pipeline assets, the dramatic increase in cash burn and the royalty dispute present material financial headwinds. Investors should monitor the resolution of the Alexion dispute and the company's ability to manage its cash burn.
