— Ledger Desk · analyst thesis

Bull case

upside

Public via SPAC March 26, 2026 — $302M gross proceeds. Aurora is a modular networked photonic system with real-time error correction and 12 logical GKP qubits. First on-chip GKP state generation (June 2025). DARPA QBI Stage B Stage B. Negotiating up to C$390M additional Canadian funding for photonic/semiconductor manufacturing.

Bear case

downside

Stock dropped 67% premarket May 4, 2026 after filing to register 294M resale shares — execution risk is now public-market visible. Photonic loss budgets remain unforgiving. Direct competition from PsiQuantum with 10× the capital.

Ledger Score · Xanadu

The Ledger reads sceptical

Sole photonic Stage B advancer outside US2QC; loss budgets at scale remain the central technical question.
