The $125M milestone is a realized cash event reinforcing the value of the Sanofi collaboration. Additional near-term catalysts include the mid-2027 $75M tech-transfer and the $225M US-launch milestone, plus ongoing royalties, which could support revenue visibility and valuation. However, regulatory and operational risks remain, including dependency on Sanofi's timelines and manufacturing partners.
