Analysis · CRBU · Life Sciences
Caribou is discontinuing both of its lead allogeneic CAR-T programs — vispa-cel and CB-011 — and launching a strategic alternatives process that could end in a sale or wind-down. The company cites an inability to secure financing for allogeneic CAR-T development. With $113.8M in cash as of June 30, 2026, and restructuring charges of $15M-$19M, the company is effectively acknowledging its standalone path is no longer viable. The CFO's departure is tied to execution of a strategic deal, signaling the board is actively pursuing a transaction. This is a thesis-altering event for a clinical-stage biotech: the pipeline is being abandoned and the company is for sale.
