IONSHIGH SIGNALOPPORTUNITY10-K

Ionis transitioned to a fully integrated commercial-stage biotechnology company with seven marketed medicines including two new independent commercial launches.

The company has achieved a significant commercial milestone by expanding from six to seven marketed medicines, adding DAWNZERA as the first and only approved RNA-targeted prophylactic therapy for hereditary angioedema. This represents a meaningful evolution from their previous single independent commercial launch to now having two independent commercial operations, demonstrating enhanced commercial capabilities and diversified revenue potential.
