-- How ENTA’s Mavyret royalty is calculated
ENTA’s royalty rate on Mavyret sales from ABBV is tiered, as shown in the table in #msg-142808661. The royalty rate is applied to the 50% Glecaprevir component of Mavyret (a 2-drug combination). The royalty tiers reset at the start of each calendar year (like tax brackets), so ENTA’s royalty rate is highest in the fourth calendar quarter (ENTA’s fiscal* Q1) and is lowest during the first calendar quarter (ENTA’s fiscal* Q2).
