Robust cash position of $297M (FY 2025) provides runway for 3+ years of R&D-heavy operations despite current losses

Deep pipeline with 16 active trials across 3 Phase 3 programs (erosive esophagitis, H. pylori infection, non-erosive GERD) de-risks single-product dependency

Watch Out For

Extreme revenue concentration (100% VOQUEZNA) with only $55M revenue in FY 2025 leaves zero margin for commercialization missteps or competitive pressure
Company losing $334M annually (FY 2025) on $34M R&D spend and $297M cash—at current burn rate, cash runway is <3 years without revenue acceleration or financing
Zero active job postings indicate either hiring freeze or minimal headcount growth; limited near-term career advancement visibility in a 51-200 person organization
