  Reported a net loss of $128.9 million for Q1 2026, significantly wider than $48.4 million in Q1 2025. Revenue declined sharply to $4.5 million from $32.7 million in the prior year period, partly due to a $6.6 million reduction from disputed royalties.

• Pipeline Advancement

  Provided updates on multiple clinical programs, including upcoming Phase 1 data for XmAb819 and XmAb541 in 2H26, and the initiation of a first-in-human study for XmAb412 in 3Q26.

Xencor's first-quarter financial results show a significant increase in net loss and a sharp decline in revenue year-over-year, partly driven by unrealized losses on an equity security. This financial underperformance could weigh on investor sentiment. However, the company provided extensive updates on its clinical pipeline, detailing progress for several key oncology and autoimmune programs, including XmAb819, XmAb541, XmAb942, and XmAb412, with multiple data presentations and study initiations planned for the second half of 2026 and 2027. Crucially, Xencor reaffirmed its financial guidance, projecting sufficient cash to fund operations into mid-2028, which provides a critical runway for a clinical-stage biopharmaceutical company. Investors will need to balance the immediate financial challenges against the long-term potential of the advancing pipeline and secure liquidity.
