The upside is a business-model transition, not just another data release. If Beam turns
risto-cel into its first launch and keeps
BEAM-302 on a credible
registrational path, investors can value it as a multi-asset rare-disease company instead of a single-modality science project. That supports a meaningful
rerating, but I stop short of a hypergrowth case because most value still runs through two hard clinical and regulatory gates.
