Verdict history (4 calls)

Every verdict Biotech Distilled has published on Xencor, oldest first — the full history, never a selection. How calls are scored: the track record.

  1. Watch Xencor, Inc. (XNCR) — Scientific Deep Dive for XmAb819, XmAb942 and the XmAb Pipeline Diversified platform optionality at roughly cash EV, but no de-risked near-term value driver and the crown-jewel Ultomiris royalty in active dispute with Alexion.
  2. Speculative buy speculative UPDATE: Xencor (XNCR) - The Alexion Standoff Ends at $105 Million Alexion settled the disputed Ultomiris royalty at roughly full value ($105M cash), removing the single cleanest bear argument and restoring runway through 2028, while the ESMO oral for XmAb819 provides a dated podium catalyst.
  3. Speculative buy speculative UPDATE: Xencor (XNCR) - The Hearing Problem Nobody Was Modeling Balance sheet continues to strengthen without dilution and XmAb541 earned its first regulatory designation, but on-target hearing toxicity caps monotherapy exposure and the ESMO XmAb819 data remains the key re-rating event.
  4. Buy core UPDATE: Xencor (XNCR) - Madrid Delivers: The Dose-Response Is Real XmAb819 posted a clear dose-response with 30–45.5% confirmed ORR in heavily pretreated ccRCC including belzutifan-pretreated patients, a concrete regulatory path to a tivozanib-controlled pivotal, and runway extended into 2029 with no dilution.
