Xencor delivered a substantial revenue and earnings beat for the third quarter 2026, primarily driven by a $25.0 million milestone from Astellas and robust royalty streams from Alexion and Incyte. The company reported a net income of $39.4 million, a sharp reversal from the prior year's loss, while expanding its cash runway into 2029.
