Operating Income

+7% YoY (from $356.3M to $382.8M in Q1)

Net Income

+5% YoY (from $306.6M to $322.2M in Q1)

Net income modestly increased reflecting the combined effect of strong revenue growth and controlled expense increases. However, the lower margin expansion compared with revenues indicates that rising costs such as cost of sales continued to influence the bottom line, moderating the gains seen in the prior period. " "

Cost of Sales

+27% YoY (from $72.9M to $92.5M in Q1)

Cost of Sales escalated primarily due to higher royalty expenses and increased product costs driven by stronger Tyvaso DPI sales compared to Q1 2024. These costs increased as a direct result of the higher product volumes and pricing adjustments that were set in the prior period. " "

Research & Development Expenses

+43% YoY (from $104.1M to $149.0M in Q1)

R&D expenses surged as the company ramped up investments including milestone payments and increased spending on clinical trials and innovative projects. This reflects a strategic commitment to future growth and technology development that builds on earlier period spending. " "

SG&A Expenses

+18% YoY (from $144.4M to $170.1M in Q1)

SG&A expenses increased due to a combination of growth in headcount, higher marketing and consulting expenditures, and a significant rise in share-based compensation driven by an improved stock performance relative to Q1 2024. These factors underscore an aggressive approach to scaling operations based on previous period performance. " "
