respectively. Within the US, management noted that 100% of previously identified

PKU centers of excellence have now prescribed Sephience (in addition to other

liberalization, but also cognitive and QoL benefits. Management noted a

discontinuation rate of ~20%, which is believed to be near steady state (and

somewhat below management's expectations heading into the launch). The focus for

the US launch going forward will be on achieving deeper penetration into each

center of excellence. Momentum is continuing to build ex-US as well, with JPN sales

ramping in 2Q reflecting similarly broad uptake and pricing on par with the US. In

leveraging early access programs in Latin America and the Middle East. Management
