Importantly, we added two new sources of commercial revenue with TRYNGOLZA product revenue from Ionis’ first independent launch and WAINUA royalties,” said Elizabeth L. Hougen , chief financial officer, Ionis. “In 2025, we will continue to invest in go-to-market activities for TRYNGOLZA for FCS and scale our resources to support our next planned launches, including donidalorsen for hereditary angioedema later this year. At the same time, we are investing in our next wave of medicines, including Phase 3 development and pre-commercialization activities for ION582 for Angelman syndrome. These important investments position Ionis to deliver substantial and growing product revenue; and when combined with increasing royalty revenue from anticipated partner launches, provides us with a clear path to achieve sustained positive cash flow.” Revenue Ionis’ revenue was comprised of the following: Three months ended Year ended December 31 , December 31 , 2024 2023 2024 2023 Revenue: (amounts in millions) Commercial revenue: SPINRAZA royalties $ 64 $ 62 $ 216 $ 240 WAINUA royalties 10 - 20 - Other commercial revenue: TEGSEDI and WAYLIVRA revenue, net 8 9 34 35 Other revenue 4 8 23 34 Total commercial revenue 86 79 293 309 Research and development revenue: Amortization from upfront payments 27 76 132 125 Milestone payments 30 11 106 101 License fees 34 92 71 117 Other services 6 - 24 10 Collaborative agreement revenue 97 179 333 353 WAINUA joint development revenue 44 67 79 126 Total research and development revenue 141 246 412 479 Total revenue $ 227 $ 325 $ 705 $ 788 Commercial revenue for the year ended December 31, 2024 included new sources of commercial revenue with the launch of WAINUA in the U.S. in late January 2024 and the launch of TRYNGOLZA in the U.S. in late December 2024 . SPINRAZA product sales in the U.S. increased slightly in 2024 compared to 2023. SPINRAZA product sales outside of the U.S. were impacted from an annual order from a single country that did not recur in 2024. R&D revenue decreased for the year ended December 31, 2024 compared to 2023 primarily due to the decrease in WAINUA joint development revenue as development activities relating to ATTRv-PN wound down with the launch of WAINUA. Operating Expenses Ionis’ operating expenses increased slightly for the year ended December 31, 2024 compared to 2023. SG&A expenses increased year over year primarily due to the launches of WAINUA and TRYNGOLZA, and advancing launch preparation activities for donidalorsen. R&D expenses were flat year over year. Balance Sheet As of December 31, 2024 , Ionis’ cash, cash equivalents and short-term investments were $2.3 billion , consistent with December 31, 2023 . In September 2024 , Ionis generated gross proceeds of $500 million from a public offering of its common stock. Ionis’ working capital increased as of December 31, 2024 , compared to December 31, 2023 primarily from the Company’s lower current liabilities as a result of lower deferred contract revenue. 2025 Financial Guidance The Company’s 2025 financial guidance reflects its evolution to a fully integrated commercial-stage biotechnology company independently launching its first medicine, TRYNGOLZA, and advancing commercialization efforts for multiple additional upcoming planned launches. As a result, the Company expects to earn substantial revenue from numerous diverse sources, with a shift toward increasing commercial revenue. Additionally, the Company expects a modest increase in its non-GAAP operating expenses in line with its plan to invest in the Company’s independent launches and advance its wholly owned pipeline of innovative medicines. The Company expects that these investments will enable Ionis to deliver accelerating value. Full Year 2025 Guidance Revenue > $600 million Operating loss on a non-GAAP basis < $495 million Cash, cash equivalents and short-term investments ~$1.7 billion Webcast Management will host a conference call and webcast to discuss Ionis’ fourth quarter and full year 2024 results at 11:30 a.m. Eastern time on Wednesday, February 19, 2025 .

Plans Required to Cover Treatment for SOD1-ALS ARLINGTON, Va., Dec. 11, 2024 /PRNewswire/ -- The Centers for Medicare & Medicaid Services (CMS) has announced a first-of-its-kind directive requiring Medicare Advantage plans to approve coverage for Qalsody, a treatment for people living with genetic SOD1-ALS. This decision reflects the ALS Association's commitment to ensuring that people living with ALS have access to promising ALS treatments without delay. "This is a victory for the entire ALS community," said Calaneet Balas, president and CEO of the ALS Association. "It's critical that FDA-approved treatments are made accessible rather than being labeled as 'experimental.' We are grateful to everyone in our community who helped make this day happen." Balas added: "We hope this sends a message to the entire rare disease community and pharmaceutical industry that new treatments can be developed and made accessible to those who will benefit from them. We need to ensure more ALS treatments are developed and approved that will help everyone living with ALS." The ALS Association played a key role in the historic CMS directive by participating and advocating for the research, approval, and accessibility of Qalsody for people living with ALS. In 2004, the ALS Association was the first to fund research into ALS-specific antisense oligonucleotide (ASO) technology, investing over $1.3 million in groundbreaking studies that laid the foundation for the development of Qalsody. This early commitment supported preclinical studies, safety trials, and the first-in-human phase 1 trial, which established SOD1 as a viable therapeutic target. In 2023, Qalsody became the first gene-based therapy approved for ALS, thanks in part to the ALS Association's efforts, including a united push from the ALS community for FDA accelerated approval. This new CMS directive provides precedent for state regulators to issue similar actions for other private insurers. According to the Valor study published in 2022, Qalsody, which was developed specifically to target the RNA produced by mutated SOD1 genes, has demonstrated significant promise in clinical trials and real-world studies. In the phase 3 VALOR trial, Qalsody reduced levels of mutated SOD1 proteins in cerebral spinal fluid by 35% within eight weeks and decreased bloodstream levels of neurofilament light chain (NfL)—a key biomarker of neurodegeneration—by 50% within 12-16 weeks. These biological changes translated into measurable clinical benefits, including slower disease progression, improved respiratory function, and enhanced quality of life after 52 weeks of treatment. Real-world data has since validated these findings, with some patients stabilizing or even experiencing improvements in motor function and quality of life. When insurance companies began denying access to Qalsody, labeling it as "experimental," the ALS Association took decisive action, working directly with CMS to launch an investigation into these unjust denials. By presenting evidence of widespread insurance rejections and demonstrating the critical need for immediate intervention. In addition to working with CMS, the ALS Association actively engaged policymakers, held strategic meetings with state and federal legislators, and served as a staunch advocate for patients, ensuring their voices were heard and their rights to life-changing treatment were upheld. The ALS Association urges anyone previously denied Qalsody by their Medicare Advantage plan to contact their ALS specialist immediately to begin the process of securing access to this critical treatment. For more information on the CMS directive visit als.org About the ALS Association The ALS Association is the largest ALS organization in the world. The ALS Association funds global research collaborations, assists people with ALS and their families through its nationwide network of care and certified clinical care centers, and advocates for better public policies for people with ALS. The ALS Association is working to make ALS a livable disease while urgently searching for new treatments and a cure. For more information about the ALS Association, visit our website at . About ALS Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease that affects nerve cells in the brain and spinal cord. Over the course of the disease, people lose the ability to move, to speak, and eventually, to breathe. The disease is always fatal, usually within five years of diagnosis. Few treatment options exist, resulting in a high unmet need for new therapies to address functional deficits and disease progression.
