Exhibit 99.1


Ionis reports second quarter 2024 financial results

WAINUATM U.S. launch progressing well; approved in Canada; EU approval decision expected this year
 
Olezarsen PDUFA December 19, 2024 for FCS
 
Positive Phase 3 donidalorsen data for HAE; preparing U.S. and EU regulatory submissions
 
On track to achieve 2024 financial guidance
 
CARLSBAD, Calif., August 1, 2024 – Ionis Pharmaceuticals, Inc. (Nasdaq: IONS) (the “Company”), today reported financial results for the second quarter of 2024.
 
“Over the first half of this year, we continued to deliver on our goal to bring a steady cadence of medicines to people with serious diseases. The WAINUA launch for hereditary ATTR polyneuropathy (ATTRv-PN) continues to progress well with AstraZeneca. QALSODY is now approved in the EU, expanding the number of patients who can benefit from the first approved treatment for a genetic form of ALS. And we are well positioned for our first independent launch with olezarsen, which was accepted for Priority Review with a December FDA action date for people with familial chylomicronemia syndrome (FCS), a serious and rare disease with no approved treatments in the U.S. Additionally, we completed enrollment in our Phase 3 olezarsen program for the much larger severe hypertriglyceridemia (sHTG) patient population, keeping us on track for data in the second half of next year. And based on recent positive Phase 3 results, we believe donidalorsen, our second planned independent U.S. launch, is positioned to be a preferred choice for people with hereditary angioedema (HAE),” said Brett P. Monia, Ph.D., chief executive officer of Ionis. “We also advanced our next wave of potentially transformational medicines, including announcing plans to independently advance ION582 into a Phase 3 study next year, based on positive data in Angelman syndrome; this program is poised to become the cornerstone of our robust wholly owned neurology pipeline. Our recent achievements, together with multiple upcoming catalysts, position Ionis to deliver next-level value for all stakeholders.”

Operating expenses increased in the second quarter and first half of 2024 compared to the same periods last year, reflecting continued strategic investments in late-stage development, including WAINUA for ATTR cardiomyopathy and olezarsen for sHTG, and commercialization efforts for WAINUA, olezarsen and donidalorsen

Second Quarter 2024 Financial Results

“Ionis is at a critical inflection point. We have achieved important development and regulatory milestones for WAINUA, olezarsen and donidalorsen, all of which have significant potential to help patients in need. In parallel, we continue to advance our next wave of potentially transformational medicines,” said Elizabeth L. Hougen, chief financial officer of Ionis. “To drive next-level of value creation for all stakeholders, we remain focused on strategically investing our capital to fully unlock the potential of our promising near-and longer-term portfolio. Our investments are focused on go-to-market preparations for our upcoming planned olezarsen and donidalorsen launches. And with our increased confidence in the potential of WAINUA and olezarsen to address broader patient populations, we are planning additional investments to scale our capabilities in line with the significant potential that these important medicines represent. Additionally, we are investing in our next wave of medicines, including pre-commercialization activities and Phase 3 development for ION582 for Angelman syndrome, which we plan to start in the first half of next year. We expect our investments today and in the years ahead will position Ionis for sustainable growth for years to come.

Commercial revenue in the second quarter and first half of 2024 included a new source of royalty revenue with the launch of WAINUA in the U.S. in late January 2024. Ionis’ commercial revenue in the second quarter and first half of 2024 also included royalties from the net sales of QALSODY, which Biogen launched in the U.S. in the second quarter of 2023 and in the EU in the second quarter of 2024.

R&D revenue in the second quarter and first half of 2024 increased compared to the same periods last year primarily due to the amortization of upfront payments from the new collaborations with Roche and Novartis that Ionis entered into during the second half of last year. In addition, license fees increased year over year as a result of new collaborations Ionis entered into during the second quarter of 2024, including the expanded donidalorsen licensing agreement with Otsuka, which now includes the Asia-Pacific region in addition to Europe. These increases were partially offset by the decrease in WAINUA joint development revenue, which decreased as development activities relating to ATTRv-PN wound down with the launch of WAINUA for this indication.

Operating Expenses
 
Ionis’ operating expenses increased in the second quarter and first half of 2024 compared to the same periods in 2023, consistent with expectations. SG&A expenses increased year over year primarily due to the launch of WAINUA in the U.S. and launch preparation activities for olezarsen and donidalorsen, including establishing the field team for olezarsen. R&D expenses decreased in the second quarter and were essentially flat in the first half of 2024 compared to the same periods last year as several late-stage studies have ended.

Balance Sheet

As of June 30, 2024, Ionis’ cash, cash equivalents and short-term investments decreased to $2.1 billion compared to $2.3 billion at December 31, 2023. The Company plans to continue deploying its capital resources toward growth opportunities, and as previously guided, projects to end 2024 with $1.7 billion in cash, cash equivalents and short-term investments. Ionis’ working capital also decreased over the same period primarily due to the Company’s lower cash and short-term investments balance. We expect to make increased strategic investments in the years ahead, with a focus on late-stage programs, wholly owned assets, and our next wave of innovative medicines.

Webcast

Management will host a conference call and webcast to discuss Ionis’ second quarter 2024 results at 11:30 a.m. Eastern time on Thursday, August 1, 2024.

Reconciliation of GAAP to Non-GAAP Basis
 
As illustrated in the Selected Financial Information in this press release, non-GAAP operating expenses, non-GAAP loss from operations, and non-GAAP net loss were adjusted from GAAP to exclude compensation expense related to equity awards and the related tax effects. Compensation expense related to equity awards are non-cash. These measures are provided as supplementary information and are not a substitute for financial measures calculated in accordance with GAAP. Ionis reports these non-GAAP results to better enable financial statement users to assess and compare its historical performance and project its future operating results and cash flows. Further, the presentation of Ionis’ non-GAAP results is consistent with how Ionis’ management internally evaluates the performance of its operations.
