Xencor (NASDAQ: XNCR) posts deeper Q1 2026 loss amid royalty dispute and Zenas write-down
Xencor (NASDAQ: XNCR) reported a significantly wider loss in Q1 2026, with revenue dropping to $4.5 million from $32.7 million year-over-year. This was primarily due to a lack of repeating Incyte milestones, reduced Ultomiris royalty revenue, and a $51.9 million unrealized loss on its equity stake in Zenas BioPharma. The company is also engaged in a royalty dispute with Alexion concerning Ultomiris U.S. payments, leading to a reversal of $6.6 million in previously recorded royalties.
