<div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">We measure stock-based compensation expense for equity-classified awards, principally related to stock
    options, RSUs, PRSUs and stock purchase rights under our ESPP based on the estimated fair value of the award on the date of grant. We recognize the value of the portion of the award that we ultimately expect to vest as stock-based compensation expense
    over the requisite service period in our condensed consolidated statements of operations. We reduce stock-based compensation expense for estimated forfeitures at the time of grant and revise in subsequent periods if actual forfeitures differ from those
    estimates. We use the Black-Scholes model to estimate the fair value of stock options granted and stock purchase rights under our ESPP.</div>

<div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">On the grant date, we use our stock price and assumptions regarding a number of variables to determine the estimated fair
    value of stock-based payment awards. These variables include, but are not limited to, our expected stock price volatility over the term of the awards, and actual and projected employee stock option exercise behaviors.</div>

    accelerated multiple-option approach. Under the accelerated multiple-option approach (also known as the graded-vesting method), we recognize compensation expense over the requisite service period for each separately vesting tranche of the award as
    though the award were in substance multiple awards, which results in the expense being front-loaded over the vesting period.</div>

    evaluate the status of each legal matter and assess our potential financial exposure. If we consider the potential loss from any legal proceeding to be probable and we can reasonably estimate the amount, we accrue a liability for the estimated loss.
    The outcome of any proceeding is not determinable in advance. Therefore, we are required to use significant judgment to determine the probability of a loss and whether the amount of the loss is reasonably estimable. Our assessment of a potential
    liability and the amount of accruals we recorded are based only on the information available to us at the time. As additional information becomes available, we reassess the potential liability related to the legal proceeding and may revise our

<div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">On January 19, 2022, a purported stockholder of Ionis filed a stockholder derivative complaint in the Delaware Court of
    Chancery captioned Leo Shumacher, et al. v. Joseph Loscalzo, et al., C.A. No. 2022-0059, or the Shumacher Action. The complaint names Ionis&#8217; board of directors, or the Board, as defendants and names Ionis as a nominal defendant. The Shumacher Action
    Plaintiff asserts a breach of fiduciary duty claim against the Board for awarding and receiving allegedly excessive compensation. The Shumacher Action Plaintiff also asserts an unjust enrichment claim against the non-executive directors as a result of
    the compensation they received. The complaint seeks, among other things, damages, restitution, attorneys&#8217; fees and costs, and such other relief as deemed just and proper by the court. On March 18, 2022, Ionis and the Board moved to dismiss the
    complaint. On May 24, 2022, the parties entered into a Stipulation and Agreement of Compromise, Settlement and Release.</div>

<div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">On May 25, 2022, another purported stockholder of Ionis filed a stockholder derivative complaint also in the Delaware
    Court of Chancery captioned Robert S. Cohen, et al. v. Joseph Loscalzo, et al., C.A. No. 2022-0453, or the Cohen Action. The complaint names the Board as defendants and names Ionis as a nominal defendant. The Cohen Action Plaintiff asserts claims for
    breach of fiduciary duty, unjust enrichment, aiding and abetting breaches of fiduciary duty, and waste against the Board for awarding and receiving allegedly excessive non-executive director compensation for the years 2018, 2019, and 2020. On June 2,
    2022, the Cohen Action Plaintiff filed a motion to consolidate the related Cohen Action and Shumacher Action. On July 5, 2022, the Court denied the motion to consolidate in favor of the settlement pending in the Shumacher Action.</div>

<div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">On July 18, 2022, Ionis filed a Form 8-K disclosing the pending settlement and attaching the Notice of Pendency of
    Settlement of Action. On September 21, 2022, the Court held a hearing to consider whether the terms of the settlement should be approved, at which hearing the Cohen Action plaintiff objected to the settlement. At the conclusion of the hearing, the
    Court declined to approve the settlement and directed the parties to meet and confer on the issue of the scope of the release. On February 7, 2023, the parties entered into an Amended Stipulation and Agreement of Compromise, Settlement and Release,
    which folded the Cohen Action into the settlement, or the Revised Settlement. The settlement did not have a material impact on our condensed consolidated financial statements. On April 24, 2023, the Court issued an Order and Final Judgment approving
    the Revised Settlement and dismissing the Shumacher and Cohen Actions, and all claims contained therein, with prejudice. The Order does not contain any admission of wrongdoing by any defendant.</div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">We were founded over 30 years ago to deliver innovative medicines for diseases with great medical need. Today, we are
    building on our advancements in RNA-targeted therapeutics to move us closer to achieving our vision to be the leader in genetic medicines. We believe our medicines have the potential to pioneer new markets, change standards of care and transform the
    lives of people with devastating diseases. We currently have four marketed medicines: QALSODY, SPINRAZA, TEGSEDI and WAYLIVRA. On April 25, 2023, the U.S. Food and Drug Administration, or FDA, granted Biogen accelerated approval of QALSODY for the
    treatment of superoxide dismutase 1 amyotrophic lateral sclerosis, or SOD1-ALS. Additionally, the FDA accepted our New Drug Application, or NDA, of eplontersen for polyneuropathy caused by hereditary TTR amyloidosis, or ATTRv-PN. Eplontersen&#8217;s
    Prescription Drug User Fee Act, or PDUFA, date is December 22, 2023. We also have a rich innovative late- and mid-stage pipeline primarily focused on our leading cardiovascular and neurology franchises. For the second consecutive quarter, we expanded
    our late-stage pipeline with the start of Roche&#8217;s Phase 3 study of IONIS-FB-L<sub>Rx</sub> in patients with immunoglobulin A nephropathy, or IgAN, in the second quarter of 2023. Prior to this, GSK initiated a Phase 3 program of bepirovirsen in the
    first quarter of 2023.</div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">We believe our substantial and sustainable revenue and strong balance sheet enable us to continue investing in our
    commercial readiness efforts for multiple late-stage programs and our innovative pipeline. By continuing to focus on these priorities, we believe we are well positioned to drive future growth and to deliver increasing value for patients and
    shareholders.</div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">Our revenue increased in the second quarter and first half of 2023 compared to the same periods in 2022 because of
    increased payments from partnered programs. We believe our substantial and sustainable revenue is an important source of funding that supports our investments to bring potentially transformational medicines to the market.</div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">Commercial revenue for the second quarter and first half of 2023 included $61 million and $111 million from SPINRAZA
    royalties, respectively. Global SPINRAZA product sales of $437 million and $880 million were essentially flat for the second quarter and first half of 2023, respectively, compared to the same periods in 2022, reflecting SPINRAZA&#8217;s resilience against
    emerging competition. Our commercial revenue in the second quarter and first half of 2023 also included royalties from the U.S. launch of QALSODY.</div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">Our financial results for the three and six months ended&#160;June 30, 2023 and 2022 reflected the cost-sharing provisions related to our collaboration with AstraZeneca to develop and commercialize eplontersen for the treatment of ATTR. Under the terms of
    the collaboration agreement, AstraZeneca is currently paying 55 percent of the costs associated with the ongoing global Phase 3 development program. Because we are leading and conducting the Phase 3 development program, we are recognizing as R&amp;D
    revenue the 55 percent of cost-share funding AstraZeneca is responsible for, net of our share of AstraZeneca&#8217;s development expenses, in the same period we incur the related development expenses.</div>

  <div><br />
  </div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">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., we are recognizing cost-share funding we receive from AstraZeneca related to these activities as a reduction of our medical affairs and commercialization expenses, which we classify as
    R&amp;D and selling, general and administrative, or SG&amp;A expenses, respectively. We expect our medical affairs and commercialization expenses to increase as eplontersen advances toward the market under our collaboration with AstraZeneca.</div>

    increased compared to the same periods in 2022. Our R&amp;D expenses increased as we advanced our pipeline, which included an increase in the costs associated with our clinical studies as most of our Phase 3 studies were either fully enrolled or
    approaching full enrollment at the end of June 2023. Our SG&amp;A expenses increased due to expenses related to our go-to-market activities for eplontersen, olezarsen and donidalorsen.

    indications we may be studying. Furthermore, as we obtain results from trials, we may elect to discontinue clinical trials for certain drug candidates in certain indications in order to focus our resources on more promising drug candidates or
    indications. Our Phase 1 and Phase 2 programs are clinical research programs that fuel our Phase 3 pipeline. When our medicines are in Phase 1 or Phase 2 clinical trials, they are in a dynamic state in which we may adjust the development strategy for
    each medicine. Although we may characterize a medicine as &#8220;in Phase 1&#8221; or &#8220;in Phase 2,&#8221; it does not mean that we are conducting a single, well-defined study with dedicated resources. Instead, we allocate our internal resources on a shared basis across
    numerous medicines based on each medicine&#8217;s particular needs at that time. This means we are constantly shifting resources among medicines. Therefore, what we spend on each medicine during a particular period is usually a function of what is required
    to keep the medicines progressing in clinical development, not what medicines we think are most important. For example, the number of people required to start a new study is large, the number of people required to keep a study going is modest and the
    number of people required to finish a study is large. However, such fluctuations are not indicative of a shift in our emphasis from one medicine to another and cannot be used to accurately predict future costs for each medicine. Because we always have
    numerous medicines in preclinical and varying stages of clinical research, the fluctuations in expenses from medicine to medicine, in large part, offset one another. If we partner a medicine, it may affect the size of a trial, its timing, its total
    cost and the timing of the related costs.</div>

    proceeds to repurchase $434.1 million in principal of our 0.125% Notes. As a result, we recorded an $11.3 million gain on early retirement of debt, which reflects the difference between the amount we paid to repurchase a portion of our 0.125% Notes and
    the net carrying balance of the liability at the time that we repurchased the debt. Refer to Part I, Item 1, Note 12, <span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; font-style: italic;">Convertible Debt</span>, in the

    expenditures over five years pursuant to Internal Revenue Code, or IRC, Section 174. Additionally, we expect to reflect the royalty purchase agreement with Royalty Pharma as a taxable sale, requiring us to include the proceeds from the sale, net of
    currently deductible issuance costs, as taxable income in 2023. The resulting tax liability is partially offset by the utilization of our R&amp;D tax credits.</div>

  </div>

  <div style="text-align: justify; text-indent: 36pt; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">In July 2017, we purchased the building that houses our primary R&amp;D facility for $79.4 million and our manufacturing facility for
    $14.0 million. We financed the purchase of these two facilities with mortgage debt of $60.4 million in total. Our manufacturing facility mortgage, which has an interest rate of 4.20 percent, matures in August 2027.</div>

  <div><br />
  </div>

  <div style="text-align: justify; text-indent: 36pt; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">In October 2022, we concurrently entered into two purchase and sale agreements with a real estate investor. Under the agreements, we sold
    and leased back the facilities at our headquarters location in Carlsbad, California and will sell, subject to meeting certain closing conditions, two lots of undeveloped land adjacent to our headquarters. We sold the facilities at our headquarters,
    which includes our primary R&amp;D facility, for a total purchase price of $263.4 million and we expect to receive total proceeds of $33.0 million upon the close of the sale of the two lots. We used a portion of the sale proceeds to extinguish our
    mortgage debt on our primary R&amp;D facility of $51.3 million.</div>

  <div><br />
  </div>

  <div style="text-align: justify; text-indent: 36pt; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">In October 2022, we entered into a build-to-suit lease agreement to lease a development chemistry and manufacturing facility in Oceanside,
    California. The lessor will develop and construct a 217,000-square-foot building, composed of manufacturing space, office space, research and development space and warehouse space. We will design and construct tenant improvements to customize the
    facility&#8217;s interior space. We will lease the facility for an initial term of 20 years and 3 months with options to extend the lease for two additional terms of 10 years each. The lease will commence when the lessor&#8217;s construction is complete and we are
    able to begin constructing tenant improvements. Under the lease, the lessor was to commence grading of the land upon which our building is to be constructed on or before July 31, 2023. Because the lessor did not commence grading of the land on or
    before July 31, 2023, we sent a notice of termination to the lessor on August 1, 2023. If the lessor does not commence grading of the land by August 31, 2023, the lease will terminate. We do not believe the potential termination of the lease will
    impact our ability to successfully commercialize our medicines.</div>

  </div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">We are exposed to changes in interest rates primarily from our investments in certain short-term investments. We primarily
    invest our excess cash in highly liquid short-term investments of the U.S. Treasury and reputable financial institutions, corporations, and U.S. government agencies with strong credit ratings. We typically hold our investments for the duration of the
    term of the respective instrument. We do not utilize derivative financial instruments, derivative commodity instruments or other market risk sensitive instruments, positions or transactions to manage exposure to interest rate changes. Accordingly, we
    believe that, while the securities we hold are subject to changes in the financial standing of the issuer of such securities, we are not subject to any material risks arising from changes in interest rates, foreign currency exchange rates, commodity
    prices, equity prices or other market changes that affect market risk sensitive instruments.</div>

  </div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">We are also exposed to changes in foreign currency exchange rates as we have foreign subsidiaries with functional
    currencies other than the U.S. dollar. We translate our subsidiaries&#8217; functional currencies into our reporting currency, the U.S. dollar. As a result, our financial position, results of operations and cash flows can be affected by market fluctuations
    in the foreign currencies to U.S. dollar exchange rate, which are difficult to predict. A hypothetical 10 percent change in foreign exchange rates during any of the periods presented would not have had a material impact on our condensed consolidated
    financial statements.</div>

  </div>

  <div style="text-align: justify; font-family: 'Times New Roman', Times, serif; font-size: 10pt; font-weight: bold;">We have limited experience as a company in commercializing medicines and we will have to invest significant resources to develop our
    capabilities. If we are unable to establish effective marketing, sales, market access, distribution, and related functions, or enter into agreements with third parties to commercialize our medicines, we may not be able to generate revenue from our
    medicines.</div>

  <div>
    <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">We currently rely on third parties for the commercialization of our marketed medicines, have limited experience as a
      company in commercializing medicines and will have to invest significant financial and management resources to develop the infrastructure required to successfully commercialize our medicines. There are significant risks involved in building and
      managing a sales organization, including our ability to hire, retain and incentivize qualified individuals, generate sufficient sales leads, provide adequate training to sales and marketing personnel, and effectively manage a geographically dispersed
      sales and marketing team. We will also need to scale-up existing internal support functions to aid our commercialization efforts, in particular, regulatory affairs and medical affairs. Any failure to effectively build or maintain the infrastructure
      required to successfully commercialize our medicines, including our sales, marketing, market access, distribution, and related capabilities, or scale-up our existing support functions, could adversely impact the revenue we generate from our
      medicines. In addition, if we choose to rely on third parties to assist us in commercializing our medicines, we may not be able to enter into collaborations or hire consultants or external service providers on acceptable financial terms, or at all.
      If we continue to engage third parties to assist us in the commercialization of our medicines, our product revenues and profitability may be lower than if we commercialized such medicines ourselves.</div>

  <div style="text-align: justify; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt; font-weight: bold;">If the market does not accept our medicines, including QALSODY, SPINRAZA, TEGSEDI, WAYLIVRA, eplontersen and our other
    medicines in development, we are not likely to generate substantial revenues or become consistently profitable.</div>

  </div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">Even if our medicines are authorized for marketing, our success will depend upon the medical community, patients and
    third-party payers accepting our medicines as medically useful, cost-effective, safe and convenient. Even when the FDA or foreign regulatory authorities authorize our or our partners&#8217; medicines for commercialization, doctors may not prescribe our
    medicines to treat patients. Furthermore, we and our partners may not successfully commercialize additional medicines.</div>

      or our partners may sell our medicines in the future, if we or our partners cannot agree with the government or other third-party payers regarding the price we can charge for our medicines, we may not be able to sell our medicines in that market.
      Similarly, cost control initiatives by governments or third-party payers could decrease the price received for our medicines or increase patient coinsurance to a level that makes our medicines, including QALSODY, SPINRAZA, TEGSEDI, WAYLIVRA and
      eplontersen, and our medicines in development, economically unviable. </span>If the pricing of any of our medicines decreases for any reason, it will reduce our revenue for such medicine. For example, Biogen has in the past disclosed that SPINRAZA
    revenue decreased in part due to lower pricing in the U.S. and certain rest-of-world markets.</div>

  </div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">For example, TEGSEDI requires periodic blood and urine monitoring and is available in the U.S. only through a risk
    evaluation and mitigation strategy (&#8220;REMS&#8221;) program. In addition, the product label for TEGSEDI in the U.S. has a boxed warning for thrombocytopenia and glomerulonephritis. Our main competitors in the U.S. market for TEGSEDI are patisiran and
    vutrisiran, both marketed by Alnylam Pharmaceuticals, Inc. Neither patisiran nor vutrisiran has a boxed warning nor does either require use of a REMS program. Additionally, the product label for WAYLIVRA in the European Union, or EU, requires regular
    blood monitoring. In each case, these label requirements have negatively affected our ability to attract and retain patients for these medicines. If we or our partner cannot effectively maintain patients on TEGSEDI or WAYLIVRA, including due to
    limitations or restrictions on the ability to conduct periodic blood and urine monitoring of our patients as a result of the COVID-19 pandemic, we may not be able to generate substantial revenue from TEGSEDI or WAYLIVRA sales.</div>

      adequate coverage and payment rates for our medicines, including </span><span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; font-weight: bold; color: #000000;">QALSODY</span><span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; color: #000000;">,</span><span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; font-weight: bold;"> SPINRAZA, TEGSEDI, WAYLIVRA and eplontersen, and our medicines in development, our revenue will be

  <div><br />
  </div>

  <div style="text-align: justify; text-indent: 36pt; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">In both domestic and foreign markets, sales of our current and future products will depend in part upon the availability of coverage and
    reimbursement from third-party payers. The majority of patients in the U.S. who would fit within our target patient populations for our medicines have their healthcare supported by a combination of Medicare coverage, other government health programs
    such as Medicaid, managed care providers, private health insurers and other organizations. Coverage decisions may depend upon clinical and economic standards that disfavor new medicines when more established or lower cost therapeutic alternatives are
    already available or subsequently become available. Assuming coverage is approved, the resulting reimbursement payment rates might not be enough to make our medicines affordable. Even if favorable coverage status and adequate reimbursement rates are
    attained, less favorable coverage policies and reimbursement rates may be implemented in the future. Accordingly, <span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; color: #000000;">QALSODY,</span> SPINRAZA, TEGSEDI, WAYLIVRA
    and eplontersen, and our medicines in development, will face competition from other therapies and medicines for limited financial resources. We or our partners may need to conduct post-marketing studies to demonstrate the cost-effectiveness of any
    future products to satisfy third-party payers. These studies might require us to commit a significant amount of management time and financial and other resources. In addition, third-party payers may never consider our future products as cost-effective
    and adequate third-party coverage and reimbursement might not be available to enable us to maintain price levels sufficient to realize an appropriate return on investment in product development.</div>

  <div><br />
  </div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">Third-party payers, whether foreign or domestic, or governmental or commercial, are developing increasingly sophisticated
    methods of controlling healthcare costs. In addition, in the U.S., no uniform policy of coverage and reimbursement for medicines exists among third-party payers. Therefore, coverage and reimbursement for medicines can differ significantly from payer to
    payer. For example, the Affordable Care Act, or ACA, was passed in March 2010, and substantially changed the way healthcare is financed by both governmental and private insurers and continues to significantly impact the U.S. pharmaceutical industry.
    There have been judicial and Congressional challenges to certain aspects of the ACA, as well as efforts to repeal or replace certain aspects of the ACA. It is unclear how future litigation and healthcare reform measures will impact the ACA and our
    business.</div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">Further, we believe that future coverage, reimbursement and pricing will likely be subject to increased restrictions both
    in the U.S. and in international markets. In the U.S., recent health reform measures have resulted in reductions in Medicare and other healthcare funding, and there have been several recent U.S. Congressional inquiries, legislation and executive orders
    designed to, among other things, reduce drug prices, increase competition (including by enhancing support for generic and biosimilar drugs), lower out-of-pocket drug costs for patients, curtail spread pricing practices by pharmacy benefit managers, and
    foster scientific innovation to promote better health care and improved health. In addition, the Inflation Reduction Act of 2022, or the IRA, among other things, allows the U.S. Department of Health and Human Services, or HHS, to negotiate the price of
    certain single-source drugs covered under Medicare and imposes rebates under Medicare Part B and Medicare Part D. In an effort to curb Medicare patients&#8217; out-of-pocket costs for prescription drugs, the Part D redesign legislation requires manufacturers
    to contribute to the catastrophic coverage phase for Part D drugs as discounts through a manufacturer discount program. Furthermore, any reduction in reimbursement from Medicare and other government programs may result in a similar reduction in
    payments from private payers. Our future product sales may be subject to additional discounts from list price in the form of rebates and discounts provided to covered entities under the Public Health Service Act 340B drug pricing program. Changes to
    the 340B program or to Medicare or Medicaid programs at the federal or state level, including outcomes of ongoing litigation in our industry, may impact our product prices and rebate liability. Further, in February 2023, in response to President
    Biden&#8217;s executive order released in October 2022, the Secretary of the U.S. Department of HHS selected three new models for testing by the Centers for Medicare &amp; Medicaid Services Innovation Center to help lower the high cost of drugs, promote
    accessibility to life-changing drug therapies and improve quality of care. It is unclear whether or how these selected models or similar policy initiatives will impact prescription drug pricing in the future.</div>

  </div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">At the state level, legislatures have increasingly passed legislation and implemented regulations designed to control
    pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage
    importation from other countries and bulk purchasing. Third-party coverage and reimbursement for medicines may not be available or adequate in either the U.S. or international markets, which would negatively affect the potential commercial success of
    our products, our revenue and our profits.</div>

    50 countries. Specifically, SPINRAZA faces competition from onasemnogene abeparvovec, a gene therapy product that was approved in the U.S. in May 2019 and in the EU in May 2020 for the treatment of SMA, as well as risdiplam, an oral product for the
    treatment of SMA that was approved in the U.S. in August 2020 and in the EU in March 2021. Biogen has in the past disclosed that SPINRAZA revenue decreased due to a reduction in demand as a result of increased competition and that future sales of

  <div style="text-align: justify; text-indent: 39.6pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">In addition, when approved, the FDA or a foreign regulatory authority may condition approval on the performance of
    post-approval clinical studies or patient monitoring, which could be time consuming and expensive. For example, in connection with the conditional marketing approval for WAYLIVRA in the EU, we are required to conduct a post-authorization safety study
    to evaluate the safety of WAYLIVRA on thrombocytopenia and bleeding in FCS patients taking WAYLIVRA. If the results of such post-marketing studies are not satisfactory, the FDA, EC or other foreign regulatory authorities may withdraw marketing
    authorization or may condition continued marketing on commitments from us or our partners that may be expensive and time consuming to fulfill.</div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">We have entered into a collaborative arrangement with AstraZeneca to develop and commercialize eplontersen. Under the
    terms of the collaboration agreement, we and AstraZeneca will co-develop and co-commercialize eplontersen in the U.S. and AstraZeneca will have the sole right to commercialize eplontersen in all other countries, except for certain Latin American
    countries. Prior to co-commercializing eplontersen in the U.S., we will need to negotiate a co-commercialization agreement with AstraZeneca to govern the parties&#8217; performance of co-commercialization, which agreement will include a commercial plan and
    budget. As a company we do not have experience with co-commercialization arrangements. We also do not have control over the amount and timing of resources that AstraZeneca devotes to our collaboration, particularly outside of the U.S. If the
    co-commercialization arrangement for eplontersen is not successful for any reason, eplontersen may not meet our commercial objectives and our revenues for eplontersen may be limited.</div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">In addition, a Joint Steering Committee, or JSC, having equal membership from us and AstraZeneca, and various
    subcommittees oversee and coordinate the development, manufacturing, commercialization and other exploitation activities for eplontersen in the U.S. by mutual agreement. If any subcommittee cannot reach unanimous agreement on any matter within its
    respective scope of authority, such matter may be referred to the JSC for resolution. If the JSC cannot come to a mutual agreement on any particular matter, this could delay our ability to develop or commercialize eplontersen.</div>

  <div style="text-align: justify; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt; font-weight: bold;">If we are not successful in expanding our manufacturing capabilities or cannot manufacture our medicines or contract with
    a third party to manufacture our medicines at costs that allow us to charge competitive prices to buyers, we cannot market our products profitably.*</div>

  <div><br />
  </div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">To successfully commercialize any of our medicines, we need to optimize and manage large-scale commercial manufacturing
    capabilities either on a standalone basis or through a third-party manufacturer. As our drug development and commercial pipeline increases and matures, we will have a greater need for clinical trial and commercial manufacturing capacity. To that end,
    in 2022 we entered into a lease agreement (&#8220;Lease&#8221;) with a lessor to construct a new manufacturing facility in Oceanside, California to expand our manufacturing infrastructure. However, because the lessor missed a key milestone under the Lease, we sent
    a notice of termination to the lessor on August 1, 2023. If the lessor does not achieve the key milestone by August 31, 2023, the Lease will terminate. While it remains important to expand our manufacturing infrastructure in the future, we believe our
    current capabilities and those we obtain through third-party manufacturers will support our manufacturing needs while we secure a suitable alternative for our manufacturing facility.&#160; When we do secure a suitable alternative, we will incur substantial
    expenditures to build the new manufacturing facility and, following its completion, will likely need to hire and train additional staff to operate the facility. If we are not successful in executing this expansion, it could limit our ability to meet
    our manufacturing requirements and commercial objectives in the future and we will not realize the value of our investment in the expansion.</div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">In addition, we have limited experience manufacturing pharmaceutical products of the chemical class represented by our
    medicines, called oligonucleotides, on a commercial scale for the systemic administration of a medicine. There are a small number of suppliers for certain capital equipment and raw materials that we use to manufacture our medicines, and some of these
    suppliers will need to increase their scale of production to meet our projected needs for commercial manufacturing. Further, we must continue to improve our manufacturing processes to allow us to reduce our drug costs. We or our partners may not be
    able to manufacture our medicines at a cost or in quantities necessary to make commercially successful products.</div>

  </div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">Manufacturers, including us, must adhere to the FDA&#8217;s cGMP regulations and similar regulations in foreign countries, which
    the applicable regulatory authorities enforce through facilities inspection programs. We, our partners and our contract manufacturers may not comply or maintain compliance with cGMP, or similar foreign regulations. Non-compliance could significantly
    delay or prevent receipt of marketing authorizations for our medicines, including authorizations for QALSODY, SPINRAZA, TEGSEDI, WAYLIVRA and eplontersen, and our medicines in development, or could result in enforcement action after authorization that
    might limit the commercial success of our medicines, including QALSODY, SPINRAZA, TEGSEDI, WAYLIVRA and eplontersen, and our medicines in development.</div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">We rely on third-party manufacturers to supply the drug substance and drug product for TEGSEDI and drug product for
    WAYLIVRA. Any delays or disruption to our own or third-party commercial manufacturing capabilities, including any interruption to our supply chain as a result of the COVID-19 pandemic or the ongoing war between Russia and Ukraine, could limit the

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">We cannot guarantee that any of our medicines will be considered safe and effective or will be approved for
    commercialization. In addition, it is possible that QALSODY, SPINRAZA, TEGSEDI and WAYLIVRA may not be approved in additional markets or for additional indications. We and our partners must conduct time-consuming, extensive and costly clinical studies
    to demonstrate the safety and efficacy of each of our medicines before they can be approved or receive additional approvals for sale. We and our partners must conduct these studies in compliance with FDA regulations and with comparable regulations in
    other countries.</div>

  <div><br />
  </div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">We and our partners may not obtain necessary regulatory approvals on a timely basis, if at all, for our medicines. It is
    possible that regulatory agencies will not approve our medicines for marketing or QALSODY, SPINRAZA, TEGSEDI or WAYLIVRA in additional markets or for additional indications. If the FDA or another regulatory agency believes that we or our partners have
    not sufficiently demonstrated the safety or efficacy of any of our medicines, including QALSODY, SPINRAZA, TEGSEDI and WAYLIVRA, or our medicines in development, the agency will not approve the specific medicine or will require additional studies,
    which could be time consuming and expensive and delay or harm commercialization of the medicine. For example, in August 2018 we received a complete response letter from the FDA regarding the new drug application for WAYLIVRA in which the FDA determined
    that the safety concerns identified with WAYLIVRA in our clinical development program outweighed the expected benefits of triglyceride lowering in patients with FCS. We also received a Non-W from Health Canada for WAYLIVRA in November 2018.</div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">In addition, our current medicines, including QALSODY, SPINRAZA, TEGSEDI, WAYLIVRA and eplontersen are chemically similar
    to each other. As a result, a safety observation we encounter with one of our medicines could have, or be perceived by a regulatory authority to have, an impact on a different medicine we are developing. This could cause the FDA or other regulators to
    ask questions or take actions that could harm or delay our ability to develop and commercialize our medicines or increase our costs. For example, the FDA or other regulatory agencies could request, among other things, additional information or
    commitments before we can start or continue a clinical study, protocol amendments, increased safety monitoring, additional product labeling information, and post-approval commitments. This happened in connection with the conditional marketing approval
    for WAYLIVRA in the EU, as the EC is requiring us to conduct a post-authorization safety study to evaluate the safety of WAYLIVRA on thrombocytopenia and bleeding in FCS patients taking WAYLIVRA. We have ongoing post-marketing studies for WAYLIVRA and
    TEGSEDI and an EAP for WAYLIVRA. Adverse events or results from these studies or the EAPs could negatively impact our pending or future marketing approval applications for WAYLIVRA and TEGSEDI in patients with FCS or ATTRv-PN, respectively, or the
    commercial opportunity for WAYLIVRA or TEGSEDI.</div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">Any failure or delay in our clinical studies, including the studies of QALSODY, bepirovirsen, donidalorsen, eplontersen,
    IONIS-FB-L<sub>Rx,</sub> olezarsen, pelacarsen and ulefnersen, could reduce the commercial potential or viability of our medicines.</div>

  <div style="text-align: justify; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt; font-weight: bold;">We depend on third parties to conduct clinical studies for our medicines and any failure of those parties to fulfill their

  </div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">We depend on independent clinical investigators, contract research organizations and other third-party service providers
    to conduct our clinical studies for our medicines and expect to continue to do so in the future. For example, we use clinical research organizations, such as Icon Clinical Research Limited, Medpace, Inc., Parexel International Corporation, Syneos
    Health, Inc. and Thermo Fisher Scientific Inc. for the clinical studies for our medicines, including donidalorsen, eplontersen, olezarsen and ulefnersen. We rely heavily on these parties for successful execution of our clinical studies, but do not
    control many aspects of their activities. For example, the investigators are not our employees, but we are responsible for ensuring that such investigators conduct each of our clinical studies in accordance with the general investigational plan and
    approved protocols for the study. Third parties may not complete activities on schedule or may not conduct our clinical studies in accordance with regulatory requirements or our stated protocols. For example, some of our key vendors are experiencing
    labor shortages, which could impact their ability to perform services for us for certain of our clinical trials. The failure of these third parties to carry out their obligations, including as a result of delays or disruptions caused by the COVID-19
    pandemic, or a termination of our relationship with such third parties, could delay or prevent the development, marketing authorization and commercialization of our medicines or additional marketing authorizations for TEGSEDI and WAYLIVRA.</div>

    in Russia and surrounding countries that may be impacted by the ongoing war between Russia and Ukraine and could result in difficulties enrolling or completing our clinical trials in such areas on schedule. Furthermore, the U.S. and its European allies
    have imposed significant sanctions against Russia, including regional embargoes, full blocking sanctions, and other restrictions targeting major Russian financial institutions. The U.S. government has also indicated it will consider imposing additional
    sanctions and other similar measures in the future. Our ability to conduct clinical trials in Russia may become restricted under applicable sanctions laws, which would require us to identify alternative trial sites, and could increase our costs and
    delay the clinical development of certain of our medicines.</div>

    key development resources. We plan to continue to rely on additional collaborative arrangements to develop and commercialize some of our unpartnered medicines. However, we may not be able to negotiate favorable collaborative arrangements for these drug
    programs. If we cannot continue to secure additional collaborative partners, our revenues could decrease and the development of our medicines could suffer.</div>

  <div style="text-align: justify; text-indent: 40.8pt; margin-top: 12pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">In the U.S., under the Orphan Drug Act, the FDA may designate a medicine as an orphan drug if it is
    intended to treat a rare disease or condition affecting fewer than 200,000 individuals in the U.S. Orphan drug designation does not convey any advantage in, or shorten the duration of, the regulatory review and approval process, but it can provide
    financial incentives, such as tax advantages and user-fee waivers, as well as longer regulatory exclusivity periods. The FDA has granted orphan drug designation to eplontersen for the treatment of patients with transthyretin-mediated amyloidosis and to
    ION582 for the treatment of patients with Angelman syndrome. The FDA and EMA have granted orphan drug designation to TEGSEDI for the treatment of patients with ATTRv-PN, to WAYLIVRA for the treatment of patients with FCS, and to tominersen for the
    treatment of patients with HD. In addition, the EMA has granted orphan drug designation to WAYLIVRA for the treatment of patients with FPL. Even if approval is obtained on a medicine that has been designated as an orphan drug, we may lose orphan drug
    exclusivity if the FDA or EMA determines that the request for designation was materially defective or if we cannot assure sufficient quantity of the applicable medicine to meet the needs of patients with the rare disease or condition, or if a
    competitor is able to gain approval for the same medicine in a safer or more effective form or that makes a major contribution to patient care. If we lose orphan drug exclusivity on any of our medicines, we may face increased competition and lose
    market share for such medicine.</div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">Many of our medicines are undergoing clinical studies or are in the early stages of research and development. Most of our
    programs will require significant additional research, development, manufacturing, preclinical and clinical testing, marketing authorizations, preclinical activities and commitment of significant additional resources prior to their successful
    commercialization. In addition, as we commercialize more medicines on our own, we will need to invest significant financial resources to continue developing the infrastructure required to successfully commercialize our medicines, including the
    build-out of a new manufacturing facility. All of these activities will require significant cash. As of June 30, 2023, we had cash, cash
    equivalents and short-term investments equal to $2.4 billion. If we or our partners do not meet our goals to successfully commercialize our
    medicines, including QALSODY, SPINRAZA, TEGSEDI and WAYLIVRA, or to license certain medicines and proprietary technologies, we will need additional funding in the future. Our future capital requirements will depend on many factors such as:</div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">Because drug discovery and development require substantial lead-time and money prior to commercialization, our expenses
    have generally exceeded our revenue since we were founded in January 1989. As of June 30, 2023, we had an accumulated deficit of approximately
    $1.6 billion and stockholders&#8217; equity of approximately $0.4 billion. Most of our historical losses resulted from costs incurred in connection with our research and development programs and from selling, general and administrative costs associated
    with our operations. Most of our income has historically come from collaborative arrangements, including commercial revenue from royalties and R&amp;D revenue, with additional income from research grants and the sale or licensing of our patents, as
    well as interest income. We will now and continuing into the foreseeable future need to invest significant financial resources to develop capabilities to commercialize medicines on our own and expect that our income in the future will be driven
    primarily by commercial sales. If we do not earn substantial revenue from commercial sales, we may incur additional operating losses in the future, which could restrict our ability to successfully develop additional medicines or sustain future
    profitability.</div>

    million we received at closing, this agreement makes available to us up to an additional $625 million in milestone payments. However, these additional milestone payments are subject to satisfaction of certain conditions related to the regulatory
    approval or commercial sales of pelacarsen, in certain cases by specific deadlines. Should we not satisfy such conditions by the applicable deadlines, or if we fail to meet our obligations or default under this agreement, the actual amount of
    additional payments to us could be substantially less than the maximum amounts available thereunder.</div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">Our success depends to a significant degree upon whether we can continue to develop, secure and maintain intellectual
    property rights to proprietary products and services. However, we may not receive issued patents on any of our pending patent applications in the U.S. or in other countries and we may not be able to obtain, maintain or enforce our patents and other
    intellectual property rights, any of which could impact our ability to compete effectively. In addition, the scope of any of our issued patents may not be sufficiently broad to provide us with a competitive advantage. Furthermore, other parties may
    successfully challenge, invalidate or circumvent our issued patents or patents licensed to us so that our patent rights do not create an effective competitive barrier or revenue source.</div>

  <div style="text-align: justify; text-indent: 36pt; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">We cannot be certain that the U.S. Patent and Trademark Office, or U.S. PTO, and courts in the U.S. or the patent offices and courts in

    medicines in development as patentable. Method-of-use patents protect the use of a product for the specified method. This type of patent does not prevent a competitor from making and marketing a product that is identical to our product for an
    indication that is outside the scope of the patented method. Moreover, even if competitors do not actively promote their product for our targeted indications, physicians may prescribe these products off-label. Although off-label prescriptions may
    infringe or contribute to the infringement of method-of-use patents, the practice is common and such infringement is difficult to prevent, even through legal action.</div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">From time to time, we have to defend our intellectual property rights. If we are involved in an intellectual property
    dispute, we may need to litigate to defend our rights or assert them against others. Disputes can involve arbitration, litigation or proceedings declared by the U.S. PTO or the International Trade Commission or foreign patent authorities. Even if
    resolved in our favor, litigation or other legal proceedings relating to intellectual property claims may cause us to incur significant expenses and could distract our technical and management personnel from their normal responsibilities. In addition,
    there could be public announcements of the results of hearings, motions or other interim proceedings or developments and if securities analysts or investors perceive these results to be negative, it could have a substantial adverse effect on the price

    may have to discontinue an important product or product line, alter our products and processes, pay license fees or cease certain activities. We may not be able to obtain a license to needed intellectual property on favorable terms, if at all. There
    are many patents issued or applied for in the biotechnology industry, and we may not be aware of patents or patent applications held by others that relate to our business. This is especially true since patent applications in the U.S. are filed

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">Our business exposes us to potential product liability risks that are inherent in the testing, manufacturing, marketing
    and sale of therapeutic products, including potential product liability claims related to QALSODY, SPINRAZA, TEGSEDI and WAYLIVRA, and our medicines in development. We have clinical study insurance coverage and commercial product liability insurance
    coverage. However, this insurance coverage may not be adequate to cover claims against us, or be available to us at an acceptable cost, if at all. Regardless of their merit or eventual outcome, product liability claims may result in decreased demand
    for our medicines, injury to our reputation, withdrawal of clinical study volunteers and loss of revenues. Thus, whether or not we are insured, a product liability claim or product recall may result in losses that could be material.</div>

  </div>

  <div style="text-align: justify; text-indent: 36pt; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">We are dependent on the principal members of our management and scientific staff, and as we move towards commercializing medicines on our
    own, we will become increasingly dependent on the principal members of our commercial team. We do not have employment agreements with any of our employees that would prevent them from leaving us. The loss of our management, key scientific or commercial
    employees might slow the achievement of important research and development or commercial goals. It is also critical to our success that we recruit and retain qualified scientific personnel to perform research and development work and that we recruit
    and retain qualified marketing, sales, market access, distribution, and related personnel to commercialize our medicines. We may not be able to attract and retain skilled and experienced&#160; personnel on acceptable terms because of intense competition for
    experienced personnel among many pharmaceutical and health care companies, universities and non-profit research institutions. In addition, failure to succeed in clinical studies may make it more challenging to recruit and retain qualified personnel.</div>

      research organizations upon whom we rely. For example, some physician and hospital policies that were put in place as a result of the COVID-19 pandemic restricted in-person access by third parties, which in some cases impacted our commercialization
      efforts for TEGSEDI and WAYLIVRA. In addition, in December 2021, Novartis announced that enrollment for the Phase 3 HORIZON study had been delayed due to the COVID-19 pandemic.</span>&#160;<span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; color: #000000;">The COVID-19 pandemic continues to evolve, and while we believe we have not experienced material adverse effects to our business as a result of the COVID-19 pandemic, the ultimate impact of the COVID-19 pandemic or a
      similar health epidemic is highly uncertain.</span></div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">In recent years, extreme weather events and changing weather patterns have become more common. As a result, we are
    potentially exposed to varying natural disaster or extreme weather risks such as hurricanes, tornadoes, fires, droughts, floods, or other events that may result from the impact of climate change on the environment. The potential impacts of climate
    change may also include increased operating costs associated with additional regulatory requirements and investments in reducing energy, water use and greenhouse gas emissions. In addition, we currently manufacture most of our research and clinical
    supplies in a manufacturing facility located in Carlsbad, California. We manufacture the finished drug product for TEGSEDI and WAYLIVRA at third-party contract manufacturers. Biogen manufactures the finished drug product for SPINRAZA and QALSODY. The
    facilities and the equipment we, our partners and our contract manufacturers use to research, develop and manufacture our medicines would be costly to replace and could require substantial lead time to repair or replace. Our facilities or those of our
    partners or contract manufacturers may be harmed by natural disasters or other events outside our control, such as earthquakes, war, civil or political unrest, deliberate acts of sabotage, terrorism or industrial accidents such as fire and explosion,
    whether due to human or equipment error, and if such facilities are affected by a disaster or other event, our development and commercialization efforts would be delayed. Although we possess property damage and business interruption insurance coverage,
    this insurance may not be sufficient to cover all of our potential losses and may not continue to be available to us on acceptable terms, or at all. In addition, our development and commercialization activities could be harmed or delayed by a shutdown
    of the U.S. government, including the FDA.</div>

  <div><br />
  </div>

  <div style="text-align: justify; font-family: 'Times New Roman', Times, serif; font-size: 10pt; font-weight: bold;">We are dependent on information technology systems, infrastructure and data, which exposes us to data security risks.</div>

  <div><br />
  </div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">We are dependent upon our own and third-party information technology systems, infrastructure and data, including mobile
    technologies, to operate our business. The multitude and complexity of our computer systems may make them vulnerable to service interruption or destruction, disruption of data integrity, malicious intrusion, or random attacks. Likewise, data privacy or
    security incidents or breaches by employees or others may pose a risk that sensitive data, including our intellectual property, trade secrets or personal information of our employees, patients, customers or other business partners may be exposed to
    unauthorized persons or to the public. Cyber-attacks are increasing in their frequency, sophistication and intensity, with third-party phishing and social engineering attacks in particular increasing during the COVID-19 pandemic. In addition, the
    number and frequency of cybersecurity events globally may be heightened during times of geopolitical tension or instability between countries, including, for example, the ongoing war between Russia and Ukraine, as a result of which several companies
    (not including us) have reported recent cybersecurity events.</div>

  <div><br />
  </div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">Cyber-attacks could include the deployment of harmful malware, denial-of-service, social engineering and other means to
    affect service reliability and threaten data confidentiality, integrity and availability. Our business partners face similar risks and any security breach of their systems could adversely affect our security posture. A security breach or privacy
    violation that leads to disclosure or modification of or prevents access to patient information, including personally identifiable information or protected health information, could harm our reputation, compel us to comply with federal and state breach
    notification laws and foreign law equivalents, subject us to financial penalties and mandatory and costly corrective action, require us to verify the correctness of database contents and otherwise subject us to litigation or other liability under laws
    and regulations that protect personal data, any of which could disrupt our business and result in increased costs or loss of revenue. Moreover, the prevalent use of mobile devices that access confidential information increases the risk of data security
    breaches, which could lead to the loss of confidential information, trade secrets or other intellectual property. While we have invested, and continue to invest, in the protection of our data and information technology infrastructure, our efforts may
    not prevent service interruptions or identify breaches in our systems that could adversely affect our business and operations and result in the loss of critical or sensitive information, which could result in financial, legal, business or reputational
    harm to us.</div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">For planning purposes, we estimate and may disclose the timing of a variety of clinical, regulatory and other milestones,
    such as when we anticipate a certain medicine will enter clinical trials, when we anticipate completing a clinical study, or when we anticipate filing an application for, or obtaining, marketing authorization, or when we or our partners plan to
    commercially launch a medicine. We base our estimates on present facts and a variety of assumptions, many of which are outside of our control, including the impacts of the COVID-19 pandemic. If we do not achieve milestones in accordance with our or our
    investors&#8217; or securities analysts&#8217; expectations, including milestones related to QALSODY, SPINRAZA, TEGSEDI, WAYLIVRA, bepirovirsen, donidalorsen, eplontersen, IONIS-FB-L<sub>Rx,</sub> olezarsen, pelacarsen and ulefnersen, the price of our securities

  <div style="text-align: justify; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt; font-weight: bold;">If the price of our securities continues to be highly volatile, this could make it harder to liquidate your investment and
    could increase your risk of suffering a loss.</div>

  <div><br />
  </div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">The market price of our common stock, like that of the securities of many other biopharmaceutical companies, has been and
    is likely to continue to be highly volatile. These fluctuations in our common stock price may significantly affect the trading price of our securities. During the 12 months preceding June 30, 2023, the market price of our common stock ranged from $48.82 to $32.69 per share. Many factors can affect the market price of our securities, including, for example, fluctuations in our operating results, announcements
    of collaborations, clinical study results, technological innovations or new products being developed by us or our competitors, the commercial success of our approved medicines, governmental regulation, marketing authorizations, changes in payers&#8217;
    reimbursement policies, developments in patent or other proprietary rights and public concern regarding the safety of our medicines.</div>

  <div><br />
  </div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">Broad market factors may materially harm the market price of our common stock irrespective of our operating performance.
    For example, the COVID-19 pandemic, the ongoing war between Russia and Ukraine and measures taken in response thereto and the recent failure of Silicon Valley Bank caused significant disruptions of global financial markets and resulted in increased
    volatility in the trading price of our common stock. In addition, industry factors may materially harm the market price of our common stock. Nasdaq, and the market for biotechnology companies in particular, have historically experienced extreme price
    and volume fluctuations that have often been unrelated or disproportionate to the operating performance of the particular companies affected. The trading prices and valuations of these stocks, and of ours, may not be predictable. A loss of investor
    confidence in the market for biotechnology or pharmaceutical stocks or the stocks of other companies that investors perceive to be similar to us, the opportunities in the biotechnology and pharmaceutical market or the stock market in general, could
    depress our stock price regardless of our business, prospects, financial conditions or results of operations.</div>

  <div style="text-align: justify; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt; font-weight: bold;">Provisions in our certificate of incorporation, convertible notes documents, call spread hedge transaction documents and
    Delaware law may prevent stockholders from receiving a premium for their shares.*</div>

  <div><br />
  </div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">Our certificate of incorporation provides for classified terms for the members of our board of directors. Our certificate
    also includes a provision that requires at least 66 2/3 percent of our voting stockholders to approve a merger or certain other business transactions with, or proposed by, any holder of 15 percent or more of our voting stock, except in cases where
    certain directors approve the transaction or certain minimum price criteria and other procedural requirements are met.</div>

  <div><br />
  </div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">Our certificate of incorporation also requires that any action required or permitted to be taken by our stockholders must
    be taken at a duly called annual or special meeting of stockholders and may not be taken by written consent. In addition, only our board of directors, chairperson of the board or chief executive officer can call special meetings of our stockholders. We
    have in the past, and may in the future, implement a stockholders&#8217; rights plan, also called a poison pill, which could make it uneconomical for a third party to acquire our company on a hostile basis. In addition, our board of directors has the
    authority to fix the rights and preferences of, and issue shares of preferred stock, which may have the effect of delaying or preventing a change in control of our company without action by our stockholders.</div>

  <div><br />
  </div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">The provisions of our convertible senior notes could make it more difficult or more expensive for a third party to acquire
    us. Upon the occurrence of certain transactions constituting a fundamental change, holders of the notes will have the right, at their option, to require us to repurchase all of their notes or a portion of their notes, which may discourage certain types
    of transactions in which our stockholders might otherwise receive a premium for their shares over the then-current market prices.</div>

  <div><br />
  </div>

  <div style="text-align: justify; text-indent: 36pt; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"><span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; color: #000000;">In June 2023, we completed a $575 million
      offering of 1.75% Notes and used a portion of the net proceeds from the issuance of the 1.75% Notes to repurchase $434.1 million of our 0.125% Notes for $420.4 million. In April 2021, we completed a $632.5 million offering of 0% Notes and used a
      portion of the net proceeds from the issuance of the 0% Notes to repurchase $247.9 million of our 1% Notes for $257.0 million. </span><span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif;">In December 2019, we entered into
      privately negotiated exchange and/or subscription agreements with certain new investors and certain holders of our existing 1% Notes to exchange $375.6 million of our 1% Notes for $439.3 million of our 0.125% Notes, and to issue $109.5 million of our
      0.125% Notes. Additionally, in connection with the pricing of our 0% Notes and 0.125% Notes, we entered into call spread transactions in which we purchased note hedges and sold warrants. </span><span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; color: #000000;">Terminating or unwinding the call spread transactions could require us to make substantial payments to the counterparties under those agreements or may increase our stock price. The costs or any increase in
      stock price that may arise from terminating or unwinding such agreements could make an acquisition of our company significantly more expensive to the purchaser.</span></div>

  </div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">These provisions, as well as Delaware law, including Section 203 of the Delaware General Corporation Law, and other of our
    agreements, may discourage certain types of transactions in which our stockholders might otherwise receive a premium for their shares over then-current market prices, and may limit the ability of our stockholders to approve transactions that they think
    may be in their best interests.</div>

  <div><br />
  </div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">Future sales of substantial amounts of our common stock in the public market, or the perception that such sales could
    occur, could adversely affect trading prices of our securities. For example, we may issue approximately 23.0 million shares of our common stock upon conversion of our 1.75% Notes, 0% Notes and 0.125% Notes, up to 10.9 million shares in connection with
    the warrant transactions we entered into in connection with the issuance of our 0% Notes, and up to 6.6 million shares in connection with the warrant transactions we entered into in connection with the issuance of our 0.125% Notes, in each case subject
    to customary anti-dilution adjustments. The addition of any of these shares into the public market may have an adverse effect on the price of our securities.</div>

  <div><br />
  </div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">In addition, pursuant to the call spread transactions we entered into in connection with the pricing of our 0% Notes and
    0.125% Notes, the counterparties are likely to modify their hedge positions from time to time at or prior to the conversion or maturity of the notes by purchasing and selling shares of our common stock, other of our securities, or other instruments,
    including over-the-counter derivative instruments, that they may wish to use in connection with such hedging, which may have a negative effect on the conversion value of those notes and an adverse impact on the trading price of our common stock. The
    call spread transactions are expected generally to reduce potential dilution to holders of our common stock upon any conversion of our 0% Notes or 0.125% Notes or offset any cash payments we are required to make in excess of the principal amount of the
    converted 0% Notes or 0.125% Notes, as the case may be. However, the warrant transactions could separately have a dilutive effect to the extent that the market value per share of our common stock exceeds the applicable strike price of the warrants.</div>

  <div style="text-align: justify; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt; font-weight: bold;">Negative conditions in the global credit markets and financial services and other industries may adversely affect our

      experienced extreme volatility and disruptions recently, including as a result of the ongoing COVID-19 pandemic</span>&#160;<span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; color: #000000;">and war between Russia and Ukraine and
      measures taken in response thereto, and more recently, the failure of Silicon Valley Bank. These disruptions can result in severely diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth, increases
      in unemployment rates and uncertainty about economic stability. There can be no assurance that further deterioration in credit and financial markets and confidence in economic conditions will not occur. If the current equity and credit markets
      deteriorate, it may make any necessary debt or equity financing more difficult, more costly and more dilutive. Failure to secure any necessary financing in a timely manner and on favorable terms could have a material adverse effect on our operations,
      growth plans, financial performance or stock price. In addition, our insurance carriers and insurance policies covering all aspects of our business may become financially unstable or may not be sufficient to cover any or all of our losses and may not
      continue to be available to us on acceptable terms, or at all. Furthermore, due to the rapidly rising inflation rate, we may experience significantly increased costs of goods and services for our business.</span></div>

    contractors and other partners) will comply with anti-bribery laws. In particular, we do not control the actions of manufacturers and other third-party agents, although we may be liable for their actions. Violation of these laws may result in civil or

    addition, if we cannot continue to comply with the requirements of Section 404 in a timely manner, we might be subject to sanctions or investigation by regulatory authorities, such as the SEC, the Public Company Accounting Oversight Board, or PCAOB, or

  <div style="text-align: left; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt; font-style: italic; font-weight: bold;">Risks related to taxes</div>

  <div><br />
  </div>

  <div style="text-align: justify; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt; font-weight: bold;">Our ability to use our net operating loss carryovers and certain other tax attributes may be limited.</div>

  <div><br />
  </div>

  <div style="text-align: justify; text-indent: 36pt; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">Under the Internal Revenue Code of 1986, as amended, or the Code, a corporation is generally allowed a deduction for net operating losses,
    or NOLs, carried over from a prior taxable year. Under the Code, we can carry forward our NOLs to offset our future taxable income, if any, until such NOLs are used or expire. The same is true of other unused tax attributes, such as tax credits.</div>

  <div><br />
  </div>

  <div style="text-align: justify; text-indent: 36pt; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">Under the current U.S. federal income tax law, U.S. federal NOLs generated in taxable years beginning after December 31, 2017 may be
    carried forward indefinitely, but the deductibility of such U.S. federal NOLs is limited to 80 percent of taxable income. It is uncertain if and to what extent various states will conform to current U.S. federal income tax law, and there may be periods
    during which states suspend or otherwise limit the use of NOLs for state income tax purposes.</div>

  <div><br />
  </div>

  <div style="text-align: left; text-indent: 36pt; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">In addition, under Sections 382 and 383 of the Code, and corresponding provisions of state law, if a corporation undergoes an &#8220;ownership
    change,&#8221; which is generally defined as a greater than 50 percentage-point cumulative change, by value, in its equity ownership over a three-year period, the corporation&#8217;s ability to use its pre-change NOL carryforwards and other pre-change tax
    attributes to offset its post-change income or taxes may be limited. We may experience ownership changes in the future as a result of subsequent shifts in our stock ownership, some of which may be outside of our control. If an ownership change occurs
    and our ability to use our NOL carryforwards or other tax attributes is materially limited, it would harm our future operating results by effectively increasing our future tax obligations. As a result of the Akcea Merger, we are subject to the separate
    return limitation year, or SRLY, rules. Under the SRLY rules, our utilization of Akcea&#8217;s pre-merger NOL and tax credit carryforwards is limited to the amount of income that Akcea contributes to our consolidated taxable income. The Akcea pre-merger tax
    attributes cannot be used to offset any of the income that Ionis contributes to our consolidated taxable income. In addition, at the state level, there may be periods during which the use of net operating losses is suspended or otherwise limited, which
    could accelerate or permanently increase state taxes owed.</div>

  <div style="text-align: justify; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt; font-weight: bold;">Our future taxable income could be impacted by changes in tax laws, regulations and treaties.</div>

  <div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">A change in tax laws, treaties or regulations, or their interpretation, of any country in which we operate could

  </div>

  <div style="text-align: justify; font-family: 'Times New Roman', Times, serif; font-size: 10pt; font-weight: bold;">We could be subject to additional tax liabilities.</div>

  <div><br />
  </div>

  <div style="text-align: justify; text-indent: 36pt; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">We are subject to U.S. federal, state, local and foreign income taxes, sales taxes in the U.S., withholding taxes and transaction taxes in
    foreign jurisdictions. Significant judgment is required in evaluating our tax positions and our worldwide provision for taxes. During the ordinary course of business, there are many activities and transactions for which the ultimate tax determination
    is uncertain. In addition, our tax obligations and effective tax rates could be adversely affected by changes in the relevant tax, accounting and other laws, regulations, principles and interpretations, including those relating to income tax nexus, by
    recognizing tax losses or lower than anticipated earnings in jurisdictions where we have lower statutory rates and higher than anticipated earnings in jurisdictions where we have higher statutory rates, by changes in foreign currency exchange rates, or
    by changes in the valuation of our deferred tax assets and liabilities. We may be audited in various jurisdictions, and such jurisdictions may assess additional taxes, sales taxes and value-added taxes against us. Although we believe our tax estimates
    are reasonable, the final determination of any tax audits or litigation could be materially different from our historical tax provisions and accruals, which could have a material adverse effect on our operating results or cash flows in the period for
    which a determination is made.</div>

    monetize a portion of our future SPINRAZA and pelacarsen royalties we are entitled to under our arrangements with Biogen and Novartis, respectively.

    future royalties as a liability, net of transaction costs. We record royalty payments made to Royalty Pharma as a reduction of the liability and amortize the transaction costs over the estimated life of the royalty stream. We account for the associated
    interest expense under the effective interest rate method, while continuing to recognize the full amount of royalty revenue in the period in which the counterparty sells the related product and recognizes the related revenue.</div>

<div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">We calculate the liability related to the sale of future royalties, effective interest rate and the related interest
    expense using our current estimate of anticipated future royalty payments under the arrangement, which we periodically reassess based on internal projections and information from our partners who are responsible for commercializing the medicines. If
    there is a material change in our estimate, we will prospectively adjust the liability related to the sale of future royalties, effective interest rate and the related interest expense.</div>

      Biogen focused on using antisense technology to advance the treatment of neurological disorders. We developed and licensed to Biogen SPINRAZA, our approved medicine to treat people with spinal muscular atrophy, or SMA. Under our 2013 strategic
      neurology collaboration, Biogen developed QALSODY (tofersen), our recently approved medicine to treat people with superoxide dismutase 1 amyotrophic lateral sclerosis, or SOD1-ALS. Under our collaborations, we and Biogen are currently developing
      numerous investigational medicines to treat neurodegenerative diseases in addition to SMA and SOD1-ALS, including medicines in development to treat people with </span>amyotrophic lateral sclerosis, or ALS<span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; color: #000000;">, Angelman Syndrome, Alzheimer&#8217;s disease</span><sub style="color: #000000;">&#160;</sub><span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; color: #000000;">and Parkinson&#8217;s disease.
      In addition to these medicines, our collaborations with Biogen include a substantial research pipeline that addresses a broad range of neurological diseases. From inception through </span>June 30, 2023<span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; color: #000000;">, we have received more than $</span>3.6<span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; color: #000000;"> billion in payments from our Biogen collaborations.</span></div>

<div style="text-align: justify; text-indent: 36pt; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">In the second quarter of 2023, we earned a $16
    million milestone payment from Biogen when the FDA approved Biogen&#8217;s New Drug Application, or NDA, for QALSODY. We recognized this milestone payment as R&amp;D revenue in full in the second quarter of 2023 because we did not have any remaining
    performance obligations related to the milestone payment. Under our collaboration agreement with Biogen, we are eligible to receive tiered royalties ranging from 11 percent to 15 percent on sales of QALSODY. Following the NDA approval in April
    2023, we began earning royalties from QALSODY sales, which we recognize as other commercial revenue in our condensed consolidated statements of operations. We will achieve the next milestone payment for QALSODY of $20 million if the European Medicines Agency approves Biogen&#8217;s Marketing Authorization Application filing of QALSODY.</div>

    since purchase rather than underlying credit deterioration for any of the issuers. We believe it is more likely than not that we will be able to hold our debt securities with declines in value to maturity. Therefore, we intend to hold these securities
    to maturity and anticipate full recovery of our debt securities&#8217; amortized cost basis at maturity.</div>

<div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">We measure stock-based compensation expense for equity-classified awards, principally related to stock
    options, RSUs, PRSUs and stock purchase rights under our ESPP based on the estimated fair value of the award on the date of grant. We recognize the value of the portion of the award that we ultimately expect to vest as stock-based compensation expense
    over the requisite service period in our condensed consolidated statements of operations. We reduce stock-based compensation expense for estimated forfeitures at the time of grant and revise in subsequent periods if actual forfeitures differ from those
    estimates. We use the Black-Scholes model to estimate the fair value of stock options granted and stock purchase rights under our ESPP.</div>

<div><br/>
  </div>

<div style="display:none;"><br/></div>
<div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">On the grant date, we use our stock price and assumptions regarding a number of variables to determine the estimated fair
    value of stock-based payment awards. These variables include, but are not limited to, our expected stock price volatility over the term of the awards, and actual and projected employee stock option exercise behaviors.</div>

<div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">We recognize compensation expense for stock options, RSUs, PRSUs and stock purchase rights under the ESPP using the
    accelerated multiple-option approach. Under the accelerated multiple-option approach (also known as the graded-vesting method), we recognize compensation expense over the requisite service period for each separately vesting tranche of the award as

    spread over the three years following the date of grant (i.e., the one-year period commencing on the date of grant and ending on the first anniversary of the date of grant, the two-year period commencing on the date of grant and ending on the second anniversary of the date of grant and the three-year period commencing on the date of grant and ending on the third anniversary of the date of grant) based on our relative total shareholder return, or TSR, as compared to a peer group of
    companies, and as measured, in each case, at the end of the applicable performance period. Under the terms of the grants, no number of PRSUs is
    guaranteed to vest and the actual number of PRSUs that will vest at the end of each performance period may be anywhere from zero percentto 150 percent of the target number depending on our relative TSR.</div>

<div style="text-align: justify; text-indent: 36pt; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">We determined the fair value of the PRSUs using a Monte Carlo model because the performance target is based on our relative TSR, which
    represents a market condition. The weighted-average grant date fair value of PRSUs granted to our executive officers for the six months ended&#160;June 30, 2023 and 2022 were $58.99 and $42.28 per share, respectively.</div>

    total unrecognized estimated stock-based compensation expense related to non-vested stock options, RSUs and PRSUs was $50.5 million, $70.7 million and $8.4 million, respectively. Our
    actual expenses may differ from these estimates because we will adjust our unrecognized stock-based compensation expense for future forfeitures, including any PRSUs that do not vest. We expect to recognize the cost of stock-based compensation expense
    related to our non-vested stock options, RSUs and PRSUs over a weighted average amortization period of 1.3 years, 1.6 years and 1.9 years, respectively.</div>

    expenditures over five years pursuant to Internal Revenue Code, or IRC, Section 174. Additionally, we expect to reflect the royalty purchase agreement with Royalty Pharma as a taxable sale, requiring us to include the proceeds from the sale, net of
    currently deductible issuance costs, as taxable income in 2023. The resulting tax liability is partially offset by the utilization of our R&amp;D tax credits.</div>

<div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">In January 2023, we entered into a royalty purchase agreement with Royalty Pharma to monetize a portion of our future
    SPINRAZA and pelacarsen royalties we are entitled to under our arrangements with Biogen and Novartis, respectively. As a result, we received an upfront payment of $500 million and we are eligible to receive up to $625 million in additional milestone
    payments. Under the terms of the agreement, Royalty Pharma will receive 25 percent of our SPINRAZA royalty payments from 2023 through 2027,
    increasing to 45 percent of royalty payments in 2028, on up to $1.5 billion in annual sales. In addition, Royalty Pharma will receive 25 percent of
    any future royalty payments on pelacarsen, our medicine in development to treat patients with elevated lipoprotein(a), or Lp(a), and cardiovascular disease. Royalty Pharma&#8217;s royalty interest in SPINRAZA will revert to us after total SPINRAZA royalty
    payments to Royalty Pharma reach either $475 million or $550 million, depending on the timing and occurrence of FDA approval of pelacarsen.</div>

    million, which we are amortizing over the estimated life of the arrangement using the effective interest rate method. We recognize royalty revenue in the period in which the counterparty sells the related product and recognizes the related revenue. We
    record royalty payments made to Royalty Pharma as a reduction of the liability.</div>

<div style="text-align: justify; text-indent: 36pt; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">In conjunction with the April 2021 offering, we entered into a call spread transaction, which was comprised of purchasing note hedges and
    selling warrants, to minimize the impact of potential economic dilution upon conversion of our <span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif;">0%</span> Notes by increasing the effective conversion price on our <span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif;">0%</span> Notes. We increased our effective conversion price to $76.39
    with the same number of underlying shares as our <span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif;">0%&#160;</span>Notes.
    The call spread cost us $46.9 million, of which $136.7
    million was for the note hedge purchase, offset by $89.8 million we received for selling the warrants. Similar to our <span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif;">0%</span> Notes, our note hedges are subject to adjustment. Additionally, our note hedges
    are exercisable upon conversion of the <span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif;">0%</span> Notes. The note
    hedges will expire upon maturity of the <span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif;">0%</span> Notes, or April
    2026. The note hedges and warrants are separate transactions and are not part of the terms of our <span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif;">0%</span> Notes. The holders of the <span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif;">0%</span> Notes do not have any rights with respect to the note hedges and warrants.</div>

    financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2022 for our Call Spread accounting policy. We

<div style="text-align: justify; text-indent: 36pt; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">As discussed above, in June 2023, we repurchased $434.1 million of our 0.125% Notes. As a result, the remaining principal balance of our
    0.125% Notes was $114.8 million as of
    June 30, 2023. Additionally, we recorded a $11.3
    million gain on the early retirement of debt, which we recorded as other income in our condensed consolidated statements of operations. The gain on the early retirement of our debt is the difference between the amount paid to repurchase our 0.125% Notes and the net carrying balance of the liability at the time that we completed the repurchase.</div>

<div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">From time to time, we are involved in legal proceedings arising in the ordinary course of our business. Periodically, we
    evaluate the status of each legal matter and assess our potential financial exposure. If we consider the potential loss from any legal proceeding to be probable and we can reasonably estimate the amount, we accrue a liability for the estimated loss.
    The outcome of any proceeding is not determinable in advance. Therefore, we are required to use significant judgment to determine the probability of a loss and whether the amount of the loss is reasonably estimable. Our assessment of a potential
    liability and the amount of accruals we recorded are based only on the information available to us at the time. As additional information becomes available, we reassess the potential liability related to the legal proceeding and may revise our
    estimates.</div>

<div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">On January 19, 2022, a purported stockholder of Ionis filed a stockholder derivative complaint in the Delaware Court of
    Chancery captioned Leo Shumacher, et al. v. Joseph Loscalzo, et al., C.A. No. 2022-0059, or the Shumacher Action. The complaint names Ionis&#8217; board of directors, or the Board, as defendants and names Ionis as a nominal defendant. The Shumacher Action
    Plaintiff asserts a breach of fiduciary duty claim against the Board for awarding and receiving allegedly excessive compensation. The Shumacher Action Plaintiff also asserts an unjust enrichment claim against the non-executive directors as a result of
    the compensation they received. The complaint seeks, among other things, damages, restitution, attorneys&#8217; fees and costs, and such other relief as deemed just and proper by the court. On March 18, 2022, Ionis and the Board moved to dismiss the
    complaint. On May 24, 2022, the parties entered into a Stipulation and Agreement of Compromise, Settlement and Release.</div>

<div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">On May 25, 2022, another purported stockholder of Ionis filed a stockholder derivative complaint also in the Delaware
    Court of Chancery captioned Robert S. Cohen, et al. v. Joseph Loscalzo, et al., C.A. No. 2022-0453, or the Cohen Action. The complaint names the Board as defendants and names Ionis as a nominal defendant. The Cohen Action Plaintiff asserts claims for
    breach of fiduciary duty, unjust enrichment, aiding and abetting breaches of fiduciary duty, and waste against the Board for awarding and receiving allegedly excessive non-executive director compensation for the years 2018, 2019, and 2020. On June 2,
    2022, the Cohen Action Plaintiff filed a motion to consolidate the related Cohen Action and Shumacher Action. On July 5, 2022, the Court denied the motion to consolidate in favor of the settlement pending in the Shumacher Action.</div>

<div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">On July 18, 2022, Ionis filed a Form 8-K disclosing the pending settlement and attaching the Notice of Pendency of
    Settlement of Action. On September 21, 2022, the Court held a hearing to consider whether the terms of the settlement should be approved, at which hearing the Cohen Action plaintiff objected to the settlement. At the conclusion of the hearing, the
    Court declined to approve the settlement and directed the parties to meet and confer on the issue of the scope of the release. On February 7, 2023, the parties entered into an Amended Stipulation and Agreement of Compromise, Settlement and Release,
    which folded the Cohen Action into the settlement, or the Revised Settlement. The settlement did not have a material impact on our condensed consolidated financial statements. On April 24, 2023, the Court issued an Order and Final Judgment approving
    the Revised Settlement and dismissing the Shumacher and Cohen Actions, and all claims contained therein, with prejudice. The Order does not contain any admission of wrongdoing by any defendant.</div>

<div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">In January 2023, we entered into a royalty purchase agreement with Royalty Pharma Investments, or Royalty Pharma, to
    monetize a portion of our future SPINRAZA and pelacarsen royalties we are entitled to under our arrangements with Biogen and Novartis, respectively. Refer to Note 11, <span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; font-style: italic;">Liability Related to Sale of Future Royalties</span>, for further details on the agreement.</div>

    future royalties as a liability, net of transaction costs. We record royalty payments made to Royalty Pharma as a reduction of the liability and amortize the transaction costs over the estimated life of the royalty stream. We account for the associated
    interest expense under the effective interest rate method, while continuing to recognize the full amount of royalty revenue in the period in which the counterparty sells the related product and recognizes the related revenue.</div>

<div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">We calculate the liability related to the sale of future royalties, effective interest rate and the related interest
    expense using our current estimate of anticipated future royalty payments under the arrangement, which we periodically reassess based on internal projections and information from our partners who are responsible for commercializing the medicines. If
    there is a material change in our estimate, we will prospectively adjust the liability related to the sale of future royalties, effective interest rate and the related interest expense.</div>

<div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">We measure stock-based compensation expense for equity-classified awards, principally related to stock
    options, RSUs, PRSUs and stock purchase rights under our ESPP based on the estimated fair value of the award on the date of grant. We recognize the value of the portion of the award that we ultimately expect to vest as stock-based compensation expense
    over the requisite service period in our condensed consolidated statements of operations. We reduce stock-based compensation expense for estimated forfeitures at the time of grant and revise in subsequent periods if actual forfeitures differ from those
    estimates. We use the Black-Scholes model to estimate the fair value of stock options granted and stock purchase rights under our ESPP.</div>

<div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">On the grant date, we use our stock price and assumptions regarding a number of variables to determine the estimated fair
    value of stock-based payment awards. These variables include, but are not limited to, our expected stock price volatility over the term of the awards, and actual and projected employee stock option exercise behaviors.</div>

<div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">We recognize compensation expense for stock options, RSUs, PRSUs and stock purchase rights under the ESPP using the
    accelerated multiple-option approach. Under the accelerated multiple-option approach (also known as the graded-vesting method), we recognize compensation expense over the requisite service period for each separately vesting tranche of the award as
    though the award were in substance multiple awards, which results in the expense being front-loaded over the vesting period.</div>

An operating segment is a component of an enterprise: (a) that engages in business activities from which it may earn revenues and incur expenses (including revenues and expenses relating to transactions with other components of the same enterprise), (b) whose operating results are regularly reviewed by the enterprise's chief operating decision maker to make decisions about resources to be allocated to the segment and assess its performance, and (c) for which discrete financial information is available. An operating segment may engage in business activities for which it has yet to earn revenues, for example, start-up operations may be operating segments before earning revenues.</p></div>

&lt;div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;In January 2023, we entered into a royalty purchase agreement with Royalty Pharma Investments, or Royalty Pharma, to
    monetize a portion of our future SPINRAZA and pelacarsen royalties we are entitled to under our arrangements with Biogen and Novartis, respectively. Refer to Note 11, &lt;span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; font-style: italic;"&gt;Liability Related to Sale of Future Royalties&lt;/span&gt;, for further details on the agreement.&lt;/div&gt;

&lt;div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;Under our agreement with Royalty Pharma, we record upfront payments and milestone payments we receive from the sale of
    future royalties as a liability, net of transaction costs. We record royalty payments made to Royalty Pharma as a reduction of the liability and amortize the transaction costs over the estimated life of the royalty stream. We account for the associated
    interest expense under the effective interest rate method, while continuing to recognize the full amount of royalty revenue in the period in which the counterparty sells the related product and recognizes the related revenue.&lt;/div&gt;

&lt;div&gt;&lt;br/&gt;

&lt;div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;We calculate the liability related to the sale of future royalties, effective interest rate and the related interest
    expense using our current estimate of anticipated future royalty payments under the arrangement, which we periodically reassess based on internal projections and information from our partners who are responsible for commercializing the medicines. If
    there is a material change in our estimate, we will prospectively adjust the liability related to the sale of future royalties, effective interest rate and the related interest expense.&lt;/div&gt;

From inception through &lt;/span&gt;June 30, 2023&lt;span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; color: #000000;"&gt;, we have received nearly $&lt;/span&gt;610&lt;span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; color: #000000;"&gt; million from these collaborations.&lt;/span&gt;&lt;/div&gt;

      commercialize eplontersen with AstraZeneca in the U.S. In addition, we granted AstraZeneca exclusive rights to commercialize eplontersen outside the U.S. In the second quarter of 2023, we earned a $&lt;/span&gt;20&lt;span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; color: #000000;"&gt; million license fee payment when we licensed rights to Latin America for eplontersen
      to AstraZeneca. We recognized the upfront payment in full in the second quarter of 2023 because AstraZeneca had full use of the license without any continuing involvement from us. &lt;/span&gt;We will achieve the next payment of up to $50 million upon the first regulatory approval under this collaboration.&lt;/div&gt;

      renal and metabolic diseases, AstraZeneca has licensed multiple medicines from us. AstraZeneca is responsible for global development, regulatory and commercialization activities and costs for each of the medicines it has licensed from us. In the
      second quarter of 2023, &lt;/span&gt;we achieved a $20 million milestone payment when AstraZeneca initiated a Phase 2b study for ION839, an
    investigational ligand-conjugated antisense, or LICA, medicine designed to inhibit the production of patatin-like phospholipase domain-containing 3, or PNPLA3, protein. We recognized these milestone payments as R&amp;amp;D revenue in full in the second
    quarter of 2023 because we did not have any remaining performance obligations related to the milestone payments. We will achieve the next payment of up to $30
    million if AstraZeneca licenses a medicine under this collaboration&lt;span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; color: #000000;"&gt;.&lt;/span&gt;&lt;/div&gt;

      Biogen focused on using antisense technology to advance the treatment of neurological disorders. We developed and licensed to Biogen SPINRAZA, our approved medicine to treat people with spinal muscular atrophy, or SMA. Under our 2013 strategic
      neurology collaboration, Biogen developed QALSODY (tofersen), our recently approved medicine to treat people with superoxide dismutase 1 amyotrophic lateral sclerosis, or SOD1-ALS. Under our collaborations, we and Biogen are currently developing
      numerous investigational medicines to treat neurodegenerative diseases in addition to SMA and SOD1-ALS, including medicines in development to treat people with &lt;/span&gt;amyotrophic lateral sclerosis, or ALS&lt;span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; color: #000000;"&gt;, Angelman Syndrome, Alzheimer&#x2019;s disease&lt;/span&gt;&lt;sub style="color: #000000;"&gt;&#160;&lt;/sub&gt;&lt;span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; color: #000000;"&gt;and Parkinson&#x2019;s disease.
      In addition to these medicines, our collaborations with Biogen include a substantial research pipeline that addresses a broad range of neurological diseases. From inception through &lt;/span&gt;June 30, 2023&lt;span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; color: #000000;"&gt;, we have received more than $&lt;/span&gt;3.6&lt;span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; color: #000000;"&gt; billion in payments from our Biogen collaborations.&lt;/span&gt;&lt;/div&gt;

&lt;div style="text-align: justify; text-indent: 36pt; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;In the second quarter of 2023, we earned a $16
    million milestone payment from Biogen when the FDA approved Biogen&#x2019;s New Drug Application, or NDA, for QALSODY. We recognized this milestone payment as R&amp;amp;D revenue in full in the second quarter of 2023 because we did not have any remaining
    performance obligations related to the milestone payment. Under our collaboration agreement with Biogen, we are eligible to receive tiered royalties ranging from 11 percent to 15 percent on sales of QALSODY. Following the NDA approval in April
    2023, we began earning royalties from QALSODY sales, which we recognize as other commercial revenue in our condensed consolidated statements of operations. We will achieve the next milestone payment for QALSODY of $20 million if the European Medicines Agency approves Biogen&#x2019;s Marketing Authorization Application filing of QALSODY.&lt;/div&gt;

      collaboration with GSK using our antisense drug discovery platform to discover and develop new medicines against targets for serious and rare diseases, including infectious diseases and some conditions causing blindness. Our collaboration with GSK
      currently includes bepirovirsen, our medicine in development targeting hepatitis B virus, or HBV. We designed this medicine to reduce the production of viral proteins associated with HBV infection. In the third quarter of 2019, following positive
      Phase 2 results, GSK licensed our HBV program. GSK is responsible for all global development, regulatory and commercialization activities and costs for the HBV program&lt;/span&gt;. From inception through June 30, 2023, we have received more than $105 million in an upfront
    payment and payments related to the HBV program.&lt;/div&gt;

&lt;div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;In the first quarter of 2023, we earned a $15 million milestone payment when GSK initiated a Phase 3 program of bepirovirsen. We recognized this milestone payment as R&amp;amp;D revenue in full in the first quarter of 2023 because we did not
    have any remaining performance obligations related to the milestone payment. We will achieve the next payment of $15 million if the FDA accepts
    an NDA filing of bepirovirsen for review.&lt;/div&gt;

    categorize all of these securities as current assets even though the stated maturity of some individual securities may be one year or more beyond the balance sheet date.&lt;/div&gt;

    we had an equity ownership interest of less than 20 percent in seven private companies and three public companies with which we conduct business.&lt;/div&gt;

&lt;div style="text-align: justify; text-indent: 36pt; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;We believe that the decline in value of these securities is temporary and is primarily related to the change in market interest rates
    since purchase rather than underlying credit deterioration for any of the issuers. We believe it is more likely than not that we will be able to hold our debt securities with declines in value to maturity. Therefore, we intend to hold these securities
    to maturity and anticipate full recovery of our debt securities&#x2019; amortized cost basis at maturity.&lt;/div&gt;

&lt;div style="text-align: left; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt; font-weight: bold;"&gt;9. Stock-based Compensation Expense&lt;/div&gt;

&lt;div&gt;&lt;br/&gt;
  &lt;/div&gt;

&lt;div style="display:none;"&gt;&lt;br/&gt;&lt;/div&gt;
&lt;div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;We measure stock-based compensation expense for equity-classified awards, principally related to stock
    options, RSUs, PRSUs and stock purchase rights under our ESPP based on the estimated fair value of the award on the date of grant. We recognize the value of the portion of the award that we ultimately expect to vest as stock-based compensation expense
    over the requisite service period in our condensed consolidated statements of operations. We reduce stock-based compensation expense for estimated forfeitures at the time of grant and revise in subsequent periods if actual forfeitures differ from those
    estimates. We use the Black-Scholes model to estimate the fair value of stock options granted and stock purchase rights under our ESPP.&lt;/div&gt;

&lt;div&gt;&lt;br/&gt;
  &lt;/div&gt;

&lt;div style="display:none;"&gt;&lt;br/&gt;&lt;/div&gt;
&lt;div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;On the grant date, we use our stock price and assumptions regarding a number of variables to determine the estimated fair
    value of stock-based payment awards. These variables include, but are not limited to, our expected stock price volatility over the term of the awards, and actual and projected employee stock option exercise behaviors.&lt;/div&gt;

&lt;div&gt;&lt;br/&gt;
  &lt;/div&gt;

&lt;div style="display:none;"&gt;&lt;br/&gt;&lt;/div&gt;
&lt;div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;We recognize compensation expense for stock options, RSUs, PRSUs and stock purchase rights under the ESPP using the
    accelerated multiple-option approach. Under the accelerated multiple-option approach (also known as the graded-vesting method), we recognize compensation expense over the requisite service period for each separately vesting tranche of the award as
    though the award were in substance multiple awards, which results in the expense being front-loaded over the vesting period.&lt;/div&gt;

&lt;div&gt;&lt;br/&gt;
  &lt;/div&gt;

&lt;div style="display:none;"&gt;&lt;br/&gt;&lt;/div&gt;
&lt;div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;For the six months ended&#160;June 30, 2023 and 2022, we used the
    following weighted-average assumptions in our Black-Scholes calculations:&lt;/div&gt;

&lt;div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;The fair value of RSUs is based on the market price of our common stock on the date of grant. The RSUs we have granted to

The RSUs we granted after June 2020 to our board of directors fully vest after one year.

&lt;div style="text-align: justify; text-indent: 36pt; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;Beginning in 2020, we added PRSU awards to the compensation for our Chief Executive Officer, Dr. Brett Monia. In 2022, we added PRSU

&lt;div style="text-align: justify; text-indent: 36pt; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;Under the terms of the PRSUs we granted in 2020 through 2022, &lt;span style="-sec-ix-hidden:Fact_3ea144f70898401099a1731ad0c7e39f"&gt;&lt;span style="-sec-ix-hidden:Fact_b531c97d5a394e3f8a5454ecd82ddb93"&gt;&lt;span style="-sec-ix-hidden:Fact_b2b6dbe875764e78b9cce0b8464216dd"&gt;one third&lt;/span&gt;&lt;/span&gt;&lt;/span&gt; of the PRSUs may vest at the end of three separate performance periods
    spread over the three years following the date of grant (i.e., the one-year period commencing on the date of grant and ending on the first anniversary of the date of grant, the two-year period commencing on the date of grant and ending on the second anniversary of the date of grant and the three-year period commencing on the date of grant and ending on the third anniversary of the date of grant) based on our relative total shareholder return, or TSR, as compared to a peer group of
    companies, and as measured, in each case, at the end of the applicable performance period. Under the terms of the grants, no number of PRSUs is
    guaranteed to vest and the actual number of PRSUs that will vest at the end of each performance period may be anywhere from zero percentto 150 percent of the target number depending on our relative TSR.&lt;/div&gt;

&lt;div&gt;&lt;br/&gt;
  &lt;/div&gt;

&lt;div style="display:none;"&gt;&lt;br/&gt;&lt;/div&gt;
&lt;div style="text-align: justify; text-indent: 36pt; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;Under the terms of the PRSUs we granted in 2023, 100 percent of the PRSUs may vest at the end of the three-year performance period
    based on our relative TSR as compared to a peer group of companies and as measured at the end of the performance period. Under the terms of the grants, no
    number of PRSUs is guaranteed to vest and the actual number of PRSUs that will vest at the end of each performance period may be anywhere from zero
    to 200 percent of the target number depending on our relative TSR.&lt;/div&gt;

&lt;div style="text-align: justify; text-indent: 36pt; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;We determined the fair value of the PRSUs using a Monte Carlo model because the performance target is based on our relative TSR, which
    represents a market condition. The weighted-average grant date fair value of PRSUs granted to our executive officers for the six months ended&#160;June 30, 2023 and 2022 were $58.99 and $42.28 per share, respectively.&lt;/div&gt;

    actual expenses may differ from these estimates because we will adjust our unrecognized stock-based compensation expense for future forfeitures, including any PRSUs that do not vest. We expect to recognize the cost of stock-based compensation expense
    related to our non-vested stock options, RSUs and PRSUs over a weighted average amortization period of 1.3 years, 1.6 years and 1.9 years, respectively.&lt;/div&gt;

&lt;div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;We measure stock-based compensation expense for equity-classified awards, principally related to stock
    options, RSUs, PRSUs and stock purchase rights under our ESPP based on the estimated fair value of the award on the date of grant. We recognize the value of the portion of the award that we ultimately expect to vest as stock-based compensation expense
    over the requisite service period in our condensed consolidated statements of operations. We reduce stock-based compensation expense for estimated forfeitures at the time of grant and revise in subsequent periods if actual forfeitures differ from those
    estimates. We use the Black-Scholes model to estimate the fair value of stock options granted and stock purchase rights under our ESPP.&lt;/div&gt;

&lt;div&gt;&lt;br/&gt;
  &lt;/div&gt;

&lt;div style="display:none;"&gt;&lt;br/&gt;&lt;/div&gt;
&lt;div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;On the grant date, we use our stock price and assumptions regarding a number of variables to determine the estimated fair
    value of stock-based payment awards. These variables include, but are not limited to, our expected stock price volatility over the term of the awards, and actual and projected employee stock option exercise behaviors.&lt;/div&gt;

&lt;div&gt;&lt;br/&gt;
  &lt;/div&gt;

&lt;div style="display:none;"&gt;&lt;br/&gt;&lt;/div&gt;
&lt;div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;We recognize compensation expense for stock options, RSUs, PRSUs and stock purchase rights under the ESPP using the
    accelerated multiple-option approach. Under the accelerated multiple-option approach (also known as the graded-vesting method), we recognize compensation expense over the requisite service period for each separately vesting tranche of the award as
    though the award were in substance multiple awards, which results in the expense being front-loaded over the vesting period.&lt;/div&gt;

&lt;div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;Beginning in 2022, the Tax Cuts and Jobs Act of 2017, or TCJA, requires taxpayers to amortize research and development
    expenditures over five years pursuant to Internal Revenue Code, or IRC, Section 174. Additionally, we expect to reflect the royalty purchase agreement with Royalty Pharma as a taxable sale, requiring us to include the proceeds from the sale, net of
    currently deductible issuance costs, as taxable income in 2023. The resulting tax liability is partially offset by the utilization of our R&amp;amp;D tax credits.&lt;/div&gt;

&lt;div&gt;&lt;br/&gt;
  &lt;/div&gt;

&lt;div style="display:none;"&gt;&lt;br/&gt;&lt;/div&gt;
&lt;div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;We recorded income tax expense of $7.8 million and $19.2 million for the three and six months ended&#160;June 30, 2023, respectively, compared to $2.3 million and $3.4 million for the same periods
    in 2022, respectively. The increase in income tax expense for the three months and six months ended&#160;June 30, 2023, compared to the same periods in 2022, relates primarily to the impact of the Royalty Pharma transaction.&lt;/div&gt;

&lt;div style="text-align: left; font-family: 'Times New Roman', Times, serif; font-size: 10pt; font-weight: bold;"&gt;11. Liability Related to Sale of Future Royalties&lt;/div&gt;

&lt;div&gt;&lt;br/&gt;
  &lt;/div&gt;

&lt;div style="display:none;"&gt;&lt;br/&gt;&lt;/div&gt;
&lt;div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;In January 2023, we entered into a royalty purchase agreement with Royalty Pharma to monetize a portion of our future
    SPINRAZA and pelacarsen royalties we are entitled to under our arrangements with Biogen and Novartis, respectively. As a result, we received an upfront payment of $500 million and we are eligible to receive up to $625 million in additional milestone
    payments. Under the terms of the agreement, Royalty Pharma will receive 25 percent of our SPINRAZA royalty payments from 2023 through 2027,
    increasing to 45 percent of royalty payments in 2028, on up to $1.5 billion in annual sales. In addition, Royalty Pharma will receive 25 percent of
    any future royalty payments on pelacarsen, our medicine in development to treat patients with elevated lipoprotein(a), or Lp(a), and cardiovascular disease. Royalty Pharma&#x2019;s royalty interest in SPINRAZA will revert to us after total SPINRAZA royalty
    payments to Royalty Pharma reach either $475 million or $550 million, depending on the timing and occurrence of FDA approval of pelacarsen.&lt;/div&gt;

&lt;div&gt;&lt;br/&gt;
  &lt;/div&gt;

&lt;div style="display:none;"&gt;&lt;br/&gt;&lt;/div&gt;
&lt;div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;We recorded the upfront payment of $500 million as a liability related to the sale of future royalties, net of transaction costs of $10.4
    million, which we are amortizing over the estimated life of the arrangement using the effective interest rate method. We recognize royalty revenue in the period in which the counterparty sells the related product and recognizes the related revenue. We
    record royalty payments made to Royalty Pharma as a reduction of the liability.&lt;/div&gt;

&lt;div&gt;&lt;br/&gt;
  &lt;/div&gt;

&lt;div style="display:none;"&gt;&lt;br/&gt;&lt;/div&gt;
&lt;div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;We determine the effective interest rate used to record interest expense under this agreement based on an estimate of
    future royalty payments to Royalty Pharma. As of June 30, 2023, the estimated effective interest rate under the agreement was 13.5 percent.&lt;/div&gt;

&lt;div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;There are numerous factors, most of which are not within our control, that could materially impact the amount and timing
    of royalty payments from Biogen and Novartis, and result in changes to our estimate of future royalty payments to Royalty Pharma. Such factors include, but are not limited to, the commercial sales of SPINRAZA, the regulatory approval and commercial
    sales of pelacarsen, competing products or other significant events. &lt;/div&gt;

&lt;div style="text-align: justify; text-indent: 36pt; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;In conjunction with the April 2021 offering, we entered into a call spread transaction, which was comprised of purchasing note hedges and
    selling warrants, to minimize the impact of potential economic dilution upon conversion of our &lt;span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif;"&gt;0%&lt;/span&gt; Notes by increasing the effective conversion price on our &lt;span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif;"&gt;0%&lt;/span&gt; Notes. We increased our effective conversion price to $76.39
    with the same number of underlying shares as our &lt;span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif;"&gt;0%&#160;&lt;/span&gt;Notes.
    The call spread cost us $46.9 million, of which $136.7
    million was for the note hedge purchase, offset by $89.8 million we received for selling the warrants. Similar to our &lt;span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif;"&gt;0%&lt;/span&gt; Notes, our note hedges are subject to adjustment. Additionally, our note hedges
    are exercisable upon conversion of the &lt;span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif;"&gt;0%&lt;/span&gt; Notes. The note
    hedges will expire upon maturity of the &lt;span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif;"&gt;0%&lt;/span&gt; Notes, or April
    2026. The note hedges and warrants are separate transactions and are not part of the terms of our &lt;span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif;"&gt;0%&lt;/span&gt; Notes. The holders of the &lt;span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif;"&gt;0%&lt;/span&gt; Notes do not have any rights with respect to the note hedges and warrants.&lt;/div&gt;

&lt;div&gt;&lt;br/&gt;
  &lt;/div&gt;

&lt;div style="display:none;"&gt;&lt;br/&gt;&lt;/div&gt;
&lt;div style="text-align: justify; text-indent: 36pt; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;We recorded the amount we paid for the note hedges and the amount we received for the warrants in additional paid-in capital in our
    condensed consolidated balance sheets. Refer to Part IV, Item 15, Note 1, &lt;span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; font-style: italic;"&gt;Organization and Significant Accounting Policies&lt;/span&gt;, of our audited
    financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2022 for our Call Spread accounting policy. We
    reassess our ability to continue to classify the note hedges and warrants in shareholders&#x2019; equity at each reporting period.&lt;/div&gt;

&lt;div style="text-align: justify; text-indent: 36pt; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;As discussed above, in June 2023, we repurchased $434.1 million of our 0.125% Notes. As a result, the remaining principal balance of our
    0.125% Notes was $114.8 million as of
    June 30, 2023. Additionally, we recorded a $11.3
    million gain on the early retirement of debt, which we recorded as other income in our condensed consolidated statements of operations. The gain on the early retirement of our debt is the difference between the amount paid to repurchase our 0.125% Notes and the net carrying balance of the liability at the time that we completed the repurchase.&lt;/div&gt;

      transaction, which was comprised of purchasing note hedges and selling warrants, to minimize the impact of potential economic dilution upon conversion of our &lt;/span&gt;0.125% Notes by increasing the effective conversion price on our 0.125% Notes&lt;span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; color: #000000;"&gt;. We increased our effective conversion price to $&lt;/span&gt;123.38&lt;span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; color: #000000;"&gt; with the same number of underlying shares as our &lt;/span&gt;0.125%&lt;span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; color: #000000;"&gt; Notes. The call spread cost us $&lt;/span&gt;52.6&lt;span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; color: #000000;"&gt; million, of which $&lt;/span&gt;108.7&lt;span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; color: #000000;"&gt; million was for the note hedge purchase, offset by $&lt;/span&gt;56.1&lt;span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; color: #000000;"&gt; million we received for selling the warrants. Similar to our &lt;/span&gt;0.125%
    Notes&lt;span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; color: #000000;"&gt;, our note hedges are subject to adjustment.

The note hedges will expire upon maturity of the

      hedges and warrants are separate transactions and are not part of the terms of our &lt;/span&gt;0.125% Notes&lt;span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; color: #000000;"&gt;. The holders of the &lt;/span&gt;0.125% Notes&lt;span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; color: #000000;"&gt; do not have any rights with respect to the note hedges and warrants. Following the repurchase of $&lt;/span&gt;434.1&lt;span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; color: #000000;"&gt; million of our &lt;/span&gt;0.125%&lt;span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; color: #000000;"&gt; Notes in June 2023, the note hedges and warrants remain outstanding.&lt;/span&gt;&lt;/div&gt;

      option of the note holders. We can settle conversions of the notes, at our election, in cash, shares of our common stock or a combination of both. We may not redeem the notes prior to maturity, and we do not have to provide a sinking fund for them.
      Holders of the notes may require us to purchase some or all of their notes upon the occurrence of certain fundamental changes, as set forth in the indentures governing the notes, at a purchase price equal to &lt;/span&gt;100 percent&lt;span style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; color: #000000;"&gt; of the principal amount of the notes to be

&lt;div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;From time to time, we are involved in legal proceedings arising in the ordinary course of our business. Periodically, we
    evaluate the status of each legal matter and assess our potential financial exposure. If we consider the potential loss from any legal proceeding to be probable and we can reasonably estimate the amount, we accrue a liability for the estimated loss.
    The outcome of any proceeding is not determinable in advance. Therefore, we are required to use significant judgment to determine the probability of a loss and whether the amount of the loss is reasonably estimable. Our assessment of a potential
    liability and the amount of accruals we recorded are based only on the information available to us at the time. As additional information becomes available, we reassess the potential liability related to the legal proceeding and may revise our
    estimates.&lt;/div&gt;

&lt;div&gt;&lt;br/&gt;
  &lt;/div&gt;

&lt;div style="display:none;"&gt;&lt;br/&gt;&lt;/div&gt;
&lt;div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;On January 19, 2022, a purported stockholder of Ionis filed a stockholder derivative complaint in the Delaware Court of
    Chancery captioned Leo Shumacher, et al. v. Joseph Loscalzo, et al., C.A. No. 2022-0059, or the Shumacher Action. The complaint names Ionis&#x2019; board of directors, or the Board, as defendants and names Ionis as a nominal defendant. The Shumacher Action
    Plaintiff asserts a breach of fiduciary duty claim against the Board for awarding and receiving allegedly excessive compensation. The Shumacher Action Plaintiff also asserts an unjust enrichment claim against the non-executive directors as a result of
    the compensation they received. The complaint seeks, among other things, damages, restitution, attorneys&#x2019; fees and costs, and such other relief as deemed just and proper by the court. On March 18, 2022, Ionis and the Board moved to dismiss the
    complaint. On May 24, 2022, the parties entered into a Stipulation and Agreement of Compromise, Settlement and Release.&lt;/div&gt;

&lt;div&gt;&lt;br/&gt;
  &lt;/div&gt;

&lt;div style="display:none;"&gt;&lt;br/&gt;&lt;/div&gt;
&lt;div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;On May 25, 2022, another purported stockholder of Ionis filed a stockholder derivative complaint also in the Delaware
    Court of Chancery captioned Robert S. Cohen, et al. v. Joseph Loscalzo, et al., C.A. No. 2022-0453, or the Cohen Action. The complaint names the Board as defendants and names Ionis as a nominal defendant. The Cohen Action Plaintiff asserts claims for
    breach of fiduciary duty, unjust enrichment, aiding and abetting breaches of fiduciary duty, and waste against the Board for awarding and receiving allegedly excessive non-executive director compensation for the years 2018, 2019, and 2020. On June 2,
    2022, the Cohen Action Plaintiff filed a motion to consolidate the related Cohen Action and Shumacher Action. On July 5, 2022, the Court denied the motion to consolidate in favor of the settlement pending in the Shumacher Action.&lt;/div&gt;

&lt;div&gt;&lt;br/&gt;
  &lt;/div&gt;

&lt;div style="display:none;"&gt;&lt;br/&gt;&lt;/div&gt;
&lt;div style="text-align: justify; text-indent: 36pt; color: #000000; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;On July 18, 2022, Ionis filed a Form 8-K disclosing the pending settlement and attaching the Notice of Pendency of
    Settlement of Action. On September 21, 2022, the Court held a hearing to consider whether the terms of the settlement should be approved, at which hearing the Cohen Action plaintiff objected to the settlement. At the conclusion of the hearing, the
    Court declined to approve the settlement and directed the parties to meet and confer on the issue of the scope of the release. On February 7, 2023, the parties entered into an Amended Stipulation and Agreement of Compromise, Settlement and Release,
    which folded the Cohen Action into the settlement, or the Revised Settlement. The settlement did not have a material impact on our condensed consolidated financial statements. On April 24, 2023, the Court issued an Order and Final Judgment approving
    the Revised Settlement and dismissing the Shumacher and Cohen Actions, and all claims contained therein, with prejudice. The Order does not contain any admission of wrongdoing by any defendant.&lt;/div&gt;
