Ionis Pharmaceuticals Achieves Q2 Growth with Surprise Profit
Ionis Pharmaceuticals Reports Unexpected Q2 Profit
Ionis Pharmaceuticals Inc. (NASDAQ: IONS) surprised the market by reporting adjusted second-quarter earnings of 85 cents, a significant contrast to an adjusted loss of $35 million in the same quarter last year.
Strong Revenue Growth and Analyst Expectations
This robust performance greatly exceeded analysts' expectations, who had predicted a consensus adjusted loss of 52 cents. Additionally, Ionis showcased remarkable resilience with a revenue increase of 10%, amounting to $132 million in the first quarter of 2025, surpassing an anticipated $125.32 million, largely influenced by heightened commercial sales.
Doubling of Revenues Through Strategic Launches
Ionis' revenue more than doubled compared to the previous year, reaching $452 million against the consensus estimate of $282.95 million. This growth is attributed to the successful launch of Tryngolza, alongside augmented royalties and research and development (R&D) revenues.
Launch of Tryngolza and Its Market Impact
Tryngolza (olezarsen), recognized as the first treatment aimed at familial chylomicronemia syndrome, generated impressive net product sales of $19 million in its second quarter on the market and $26 million in sales during the first half of 2025. The sale figures reflect the positive reception and early success of the drug.
Regulatory Advancements for Tryngolza
The drug's positive opinion from the Committee for Medicinal Products for Human Use sets a favorable stage for its approval in Europe, with a European Commission decision anticipated later in the year.
Additional Revenue Streams and Product Success
Moreover, Wainua (eplontersen), intended for treating polyneuropathy of hereditary transthyretin-mediated amyloidosis, accrued sales of $44 million, contributing $10 million in royalty revenue for the same quarter.
Ions' Spinraza (nusinersen), a critical treatment for spinal muscular atrophy, achieved global sales of $393 million, leading to a $54 million increase in royalty income.
Future Milestones for Spinraza
The higher dosage of nusinersen is currently undergoing review for marketing approval in both the U.S. and the EU, with an upcoming PDUFA date of September 22, 2025.
CEO Comments and Fiscal Guidance
Ionis CEO Elizabeth Hougen stated, "For the second time this year, we are significantly raising our financial guidance for 2025 due to a notably improved outlook, reflecting strong revenue performance and the early success of Tryngolza."
Additionally, the second quarter results prominently featured substantial revenue accrued from the licensing of sapablursen, a medication beyond their core focuses.
Updated Financial Outlook for Ionis
Ionis has modified its fiscal 2025 sales guidance range from $725 million-$750 million to $825 million-$850 million, contrasting with a consensus estimate of $754.67 million, highlighting anticipated Tryngolza sales of $75 million-$80 million.
Looking ahead, Ionis expects an adjusted operating loss of $300 million-$325 million compared to earlier guidance of below $375 million. The company currently holds approximately $2 billion in cash and short-term investments, an increase from the earlier expectation of about $1.9 billion.
