The earnings call summary and Q&A indicate strong financial performance and optimistic guidance, particularly with increased revenue guidance and global expansion. The management's confidence in product launches and pipeline development, alongside positive reception from payers and no significant barriers, suggest a positive outlook. Although some uncertainties exist, such as CMS reimbursement changes, the overall sentiment remains positive with growth prospects in multiple areas.
TTR franchise revenues $724 million, 135% year-over-year growth. Growth largely attributable to the AMVUTTRA CM launch in the U.S., achieving total TTR revenues of $543 million, representing 194% year-over-year growth. The broader balance uptake in the second full quarter of launch drove an approximate doubling of TTR cardiomyopathy revenue compared to the prior quarter.
Total net product revenues $851 million, up 103% year-over-year. Growth driven by strong performance of the TTR franchise and the AMVUTTRA ATTR-CM launch.
Rare disease portfolio sales $127 million, up 14% versus Q3 2024. Growth driven largely by ongoing patient demand.
Collaboration revenue $352 million, representing a $294 million increase compared with last year. Increase primarily due to revenue recognized under collaboration and license agreement with Roche, including $300 million of milestone revenue.
Royalty revenue $46 million, doubling compared with last year. Growth driven by higher LEQVIO sales as Novartis continues to grow the product globally.
Gross margin on product sales 77% for the quarter, compared with 80% in Q3 2024. Decrease driven by increased royalties on AMVUTTRA as higher revenues resulted in an increase in the royalty rate.
Non-GAAP R&D expenses $310 million, increased 23% compared to last year. Increase driven by costs associated with the initiation of multiple Phase III clinical studies.
Non-GAAP SG&A expenses $263 million, increased 35% compared to last year. Increase driven by increased headcount and investments in support of the AMVUTTRA ATTR cardiomyopathy launch in the U.S.
Non-GAAP operating income $476 million, representing a $507 million increase compared with last year. Growth driven by strong top line results in product sales and revenue from collaborations.
Cash, cash equivalents, and marketable securities $2.7 billion, similar to the end of 2024. Cash impacted by refinancing activities, including issuance of new convertible notes and repurchase of convertible senior notes.
