Webcast today, May 4, 2022, at 11:30 a.m. Eastern Time

CARLSBAD, Calif., May 4, 2022 - Ionis Pharmaceuticals, Inc. (Nasdaq: IONS) today reported financial results for the first quarter of 2022 and recent business achievements.

"We are off to a strong start this year highlighted by progress in our rich late- and mid-stage pipeline. We remain on track for data from the NEURO-TTRansform study of eplontersen in patients with hereditary ATTR polyneuropathy by mid-year. Assuming positive data, we plan to file for regulatory approval by the end of this year. We recently increased the size and duration of our CARDIO-TTRansform study of eplontersen in patients with ATTR cardiomyopathy. Our aim is to generate even more robust data and ensure a highly positive study outcome to successfully compete in this growing and dynamic market," said Brett P. Monia, Ph.D., chief executive officer of Ionis. "We also reported positive data from two potential best-in-class medicines. In the Phase 2b ETESIAN study, ION449, our investigational medicine targeting PCSK9, demonstrated robust LDL-C and PCSK9 reductions in statin-treated patients with hypercholesterolemia. ION449 was generally well tolerated in this study. Additional positive data from the Phase 2 study of donidalorsen demonstrated significant improvements in quality of life in people with hereditary angioedema. Looking ahead, we expect to provide additional key mid-stage data readouts and updates on our technology advancements. These upcoming catalysts, together with our recent achievements, position us well to continue to drive substantial growth and value for all stakeholders."

First Quarter 2022 Summary Financial Results

On track to achieve 2022 financial guidance, based on the following first quarter results:

•

$142 million in total revenues

•

$173 million of operating expenses on a non-GAAP basis(1) and $199 million on a GAAP basis

•

$39 million net loss on a non-GAAP basis(1) and $65 million on a GAAP basis

•

$2.1 billion of cash and short-term investments

"A key element of Ionis' financial strength is our ability to generate substantial revenue from multiple diverse sources on a sustained basis. Our first quarter financial results in which revenues grew more than 25 percent year over year were an excellent example of this. We generated revenues from our marketed products, including SPINRAZA, and from numerous partnered medicines as they advanced. Our first quarter financial results also reflect our investments in our rich late-stage pipeline and in activities to prepare for our launches of eplontersen, olezarsen and donidalorsen," said Elizabeth L. Hougen, chief financial officer of Ionis. "We are on track to meet our 2022 financial guidance. With $2.1 billion of cash, we are well capitalized with the resources we need to continue investing in our large agenda to drive substantial future growth."

First Quarter 2022 Financial Results

Revenue

Ionis' revenue was comprised of the following (amounts in millions):

The Company's revenue in the first quarter of 2022 increased more than 25 percent compared to the same period last year. The increase was driven by significant partner payments across multiple partnered programs, including $20 million from AstraZeneca for its share of the global Phase 3 program costs for eplontersen. Since Ionis is conducting the ongoing Phase 3 program for eplontersen, Ionis recognizes revenue for the reimbursements it receives from AstraZeneca for development expenses in the same period Ionis recognizes the related development expenses. Refer to the detailed table of costs and reimbursements for the eplontersen collaboration provided later in this release. The Company also earned $40 million from Biogen for advancing several neurology disease programs.

The Company successfully completed the transition of its TEGSEDI and WAYLIVRA operations in the EU and North America to Sobi in the first and second quarters of 2021, respectively. The decrease in TEGSEDI and WAYLIVRA revenue in the first quarter of 2022 compared to the same period last year was due to the shift from product sales to distribution fees based on net sales generated by Sobi. As part of the transition, Ionis restructured its commercial operations in 2021 resulting in substantial cost savings.

Operating Expenses

Ionis is advancing a large late-stage pipeline and as a result, its non-GAAP operating expenses increased in the first quarter of 2022 compared to the same period in 2021. Higher R&D expenses were driven by the expanded number of Phase 3 studies the Company is conducting, which doubled over the course of 2021 from three to six studies. Lower SG&A expenses were largely due to the substantial savings Ionis achieved from integrating Akcea and restructuring its commercial operations. These savings were offset in part by the investments Ionis made in advancing its go-to-market activities for its near-term commercial opportunities.

4

Net Loss

Ionis' net loss in the first quarter of 2022 decreased compared to the same period in 2021 primarily related to the changes in revenue and operating expenses, as discussed above.

Balance Sheet

As of March 31, 2022 and December 31, 2021, Ionis had cash, cash equivalents and short-term investments of $2.1 billion. Ionis' debt obligations and working capital did not change significantly from December 31, 2021 to March 31, 2022.

*

In October 2020, Ionis completed a merger transaction with Akcea such that following the completion of the merger Akcea became a wholly owned subsidiary of Ionis. Additionally, in December 2020 and April 2021, Ionis restructured its European operations and its North American TEGSEDI operations, respectively, as a result of entering into distribution agreements with Sobi. The Company excluded these costs from its non-GAAP amounts for the applicable periods.

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 costs related to the Akcea merger and restructured commercial operations and the related tax effects. Compensation expense related to equity awards are non-cash. Costs related to the Akcea merger and restructured commercial operations included: severance costs, retention costs and other costs related to commercial operations. Ionis has regularly reported non-GAAP measures for operating results as non-GAAP results. 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.

Summary of the Financial Impacts of the Eplontersen Collaboration with AstraZeneca

For the Three Months Ended, March 31, 2022

Ionis' financial results for the first quarter of 2022 reflected the cost-sharing provisions related to its eplontersen collaboration with AstraZeneca to develop and commercialize eplontersen for the treatment of ATTR. Under the terms of the collaboration agreement, AstraZeneca is paying 55 percent of the costs associated with the ongoing global Phase 3 development program. Because Ionis is leading and conducting the Phase 3 development program, Ionis is recognizing the 55 percent of cost-share funding AstraZeneca is responsible for as R&D revenue in the same period Ionis incurs the related development expenses. Ionis will receive $20 million from AstraZeneca related to development expenses Ionis incurred in the first quarter of 2022.

As AstraZeneca is responsible for the majority of the medical affairs and commercial costs in the U.S. and all costs associated with bringing eplontersen to market outside the U.S., Ionis is recognizing cost-share funding it receives from AstraZeneca related to these activities as a reduction of its medical affairs (R&D expenses) and commercialization expenses (SG&A expenses). In the first quarter of 2022, Ionis recognized $0.4 million and $0.2 million of medical affairs expenses and commercialization expenses for eplontersen, respectively, net of cost-share funding from AstraZeneca. Ionis expects its medical affairs and commercialization expenses to increase as this collaboration progresses.
