Organization and Significant Accounting Policies [Abstract] | |
Organization and Significant Accounting Policies | 1. Organization and Significant Accounting Policies Basis of Presentation In our consolidated financial statements we included the accounts of Ionis Pharmaceuticals, Inc. and the consolidated results of our subsidiary, Akcea Therapeutics, Inc. and its wholly owned subsidiaries (“we”, “us” or “our”). We formed Akcea in December 2014. In July 2017, Akcea completed an initial public offering, or IPO, which reduced our ownership of Akcea’s common stock below 100 percent. In October 2020, we completed a merger transaction with Akcea such that following the completion of the merger, Akcea became our wholly owned subsidiary. We will refer to this transaction as the Akcea Merger throughout the remainder of this document. We reflected changes in our ownership percentage in our financial statements as an adjustment to noncontrolling interest in the period the changes occurred . Organization and Business Activity We incorporated in California on January 10, 1989. In conjunction with our IPO, we reorganized as a Delaware corporation in April 1991. We were organized principally to develop human therapeutic medicines using antisense technology. In December 2015, we changed our name from Isis Pharmaceuticals, Inc. to Ionis Pharmaceuticals, Inc. Use of Estimates We prepare our consolidated financial statements in conformity with accounting principles generally accepted in the U.S. that require us to make estimates and assumptions that affect the amounts reported in our consolidated financial statements and accompanying notes. Actual results could differ from our estimates. Revenue Recognition We generally recognize revenue when we have satisfied all contractual obligations and are reasonably assured of collecting the resulting receivable. We are often entitled to bill our customers and receive payment from our customers in advance of recognizing the revenue. In the instances in which we have received payment from our customers in advance of recognizing revenue, we include the amounts within deferred revenue in our consolidated balance sheets. At contract inception, we analyze our collaboration arrangements to assess whether such arrangements involve joint operating activities performed by parties that are both active participants in the activities and exposed to significant risks and rewards dependent on the commercial success of such activities and therefore within the scope of ASC Topic 808, Collaborative Arrangements ASC does not address the recognition and measurement of collaborative arrangements and instead refers companies to use other authoritative accounting literature. For collaboration arrangements within the scope of ASC that contain multiple elements, we determine which elements of the collaboration reflect a vendor-customer relationship and therefore are within the scope of ASC , Revenue from Contracts with Customers . When we determine elements of a collaboration do not reflect a vendor-customer relationship, we consistently apply the reasonable and rational policy election we made by analogizing to authoritative accounting literature We evaluate the income statement classification for presentation of amounts due from or owed to other participants associated with multiple activities in a collaboration arrangement based on the nature of each separate activity. For example, in our eplontersen collaboration with AstraZeneca, we recognize funding received from AstraZeneca for co-development activities as revenue; while we recognize cost sharing payments to and from AstraZeneca associated with co-commercialization activities and co-medical affairs activities as SG&A expense and research and development expense, respectively. Steps to Recognize Revenue For elements of our contractual relationships that we account for under ASC 606, we use a five-step process to determine the amount of revenue we should recognize and when we should recognize it. The five-step process is as follows: 1. Identify the contract Accounting rules require us to first determine if we have a contract with our partner, including confirming that we have met each of the following criteria: ● We and our partner approved the contract and we are both committed to perform our obligations; ● We have identified our rights, our partner’s rights and the payment terms; ● We have concluded that the contract has commercial substance, meaning that the risk, timing, or amount of our future cash flows is expected to change as a result of the contract; and ● We believe collectability of the consideration is probable. 2. Identify the performance obligations We next identify our performance obligations, which represent the distinct goods and services we are required to provide under the contract. We frequently enter into a collaboration agreement in which we provide our partner with an option to license a medicine in the future. We may also provide our partner with an option to request that we provide additional goods or services in the future, such as active pharmaceutical ingredient, or API. We evaluate whether these options are material rights at the inception of the agreement. If we determine an option is a material right, we will consider the option a separate performance obligation. Historically, we have concluded that the options we grant to license a medicine in the future or to provide additional goods and services as requested by our partner are not material rights because these items are contingent upon future events that may not occur and are not priced at a significant discount. When a partner exercises its option to license a medicine or requests additional goods or services, then we identify a new performance obligation for that item In some cases, we deliver a license at the start of an agreement. If we determine that our partner has full use of the license and we do not have any additional material performance obligations related to the license after delivery, then we consider the license to be a separate performance obligation. Refer to the section titled, Eplontersen Collaboration with AstraZeneca 3. Determine the transaction price We then determine the transaction price by reviewing the amount of consideration we are eligible to earn under the collaboration agreement, including any variable consideration. Under our collaboration agreements, consideration typically includes fixed consideration in the form of an upfront payment and variable consideration in the form of potential milestone payments, license fees and royalties. At the start of an agreement, our transaction price usually consists of only the upfront payment. We do not typically include any payments we may receive in the future in our initial transaction price because the payments are not probable and are contingent on certain future events. We reassess the total transaction price at each reporting period to determine if we should include additional payments in the transaction price. Milestone payments are our most common type of variable consideration. We recognize milestone payments using the most likely amount method because we will either receive the milestone payment or we will not, which makes the potential milestone payment a binary event. The most likely amount method requires us to determine the likelihood of earning the milestone payment. We include a milestone payment in the transaction price once it is probable we will achieve the milestone event. Most often, we do not consider our milestone payments probable until we or our partner achieve the milestone event because the majority of our milestone payments are contingent upon events that are not within our control and/ or are usually based on scientific progress which is inherently uncertain. 4. Allocate the transaction price Next, we allocate the transaction price to each of our performance obligations. When we have to allocate the transaction price to more than performance obligation, we make estimates of the relative stand-alone selling price of each performance obligation because we do not typically sell our goods or services on a stand-alone basis. We then allocate the transaction price to each performance obligation based on the relative stand-alone selling price. We do not reallocate the transaction price after the start of an agreement to reflect subsequent changes in stand-alone selling prices. We may engage a party, independent valuation specialist to assist us with determining a stand-alone selling price for collaborations in which we deliver a license at the start of an agreement. We estimate the stand-alone selling price of these licenses using valuation methodologies, such as the relief from royalty method. Under this method, we estimate the amount of income, net of taxes, for the license. We then discount the projected income to present value. The significant inputs we use to determine the projected income of a license could include ● Estimated future product sales; ● Estimated royalties we may receive from future product sales; ● Estimated contractual milestone payments we may receive; ● Estimated expenses we may incur; ● Estimated income taxes; and ● A discount rate. We typically estimate the selling price of research and development, or R&D, services by using our internal estimates of the cost to perform the specific services. The significant inputs we use to determine the selling price of our R&D services include: ● The estimated number of internal hours we will spend performing these services; ● The estimated cost of work we will perform; ● The estimated cost of work that we will contract with third parties to perform; and ● The estimated cost of API we will use. For purposes of determining the stand-alone selling price of the R&D services we perform and the API we will deliver, accounting guidance requires us to include a markup for a reasonable profit margin. 5. Recognize revenue We recognize revenue in of ways, over time or at a point in time. We recognize revenue over time when we are executing on our performance obligation over time and our partner receives benefit over time. For example, we recognize revenue over time when we provide R&D services. We recognize revenue at a point in time when our partner receives full use of an item at a specific point in time. For example, we recognize revenue at a point in time when we deliver a license or API to a partner. For R&D services that we recognize over time, we measure our progress using an input method. The input methods we use are based on the effort we expend or costs we incur toward the satisfaction of our performance obligation. We estimate the amount of effort we expend, including the time we estimate it will take us to complete the activities, or costs we incur in a given period, relative to the estimated total effort or costs to satisfy the performance obligation. This results in a percentage that we multiply by the transaction price to determine the amount of revenue we recognize each period. This approach requires us to make numerous estimates and use significant judgement. If our estimates or judgements change over the course of the collaboration, they may affect the timing and amount of revenue that we recognize in the current and future periods. Amendments to Agreements From time to time we amend our collaboration agreements. When this occurs, we are required to assess the following items to determine the accounting for the amendment: 1) If the additional goods and/or services are distinct from the other performance obligations in the original agreement; and 2) If the goods and/or services are sold at a stand-alone selling price. If we conclude the goods and/or services in the amendment are distinct from the performance obligations in the original agreement and at a stand-alone selling price, we account for the amendment as a separate agreement. If we conclude the goods and/or services are not distinct and are sold at a stand-alone selling price, we then assess whether the remaining goods or services are distinct from those already provided. If the goods and/or services are distinct from what we have already provided, then we allocate the remaining transaction price from the original agreement and the additional transaction price from the amendment to the remaining goods and/or services. If the goods and/or services are not distinct from what we have already provided, we update the transaction price for our single performance obligation and recognize any change in our estimated revenue as a cumulative-effect adjustment. Multiple agreements From time to time, we may enter into separate agreements at or near the same time with the same partner. We evaluate such agreements to determine whether we should account for them individually as distinct arrangements or whether the separate agreements should be combined and accounted for together. We evaluate the following to determine the accounting for the agreements: ● Whether the agreements were negotiated together with a single objective; ● Whether the amount of consideration in one contract depends on the price or performance of the other agreement; or ● Whether the goods and/or services promised under the agreements are a single performance obligation. Our evaluation involves significant judgment to determine whether a group of agreements might be so closely related that accounting guidance requires us to account for them as a combined arrangement. Refer to Part IV, Item 15, Note 7, Collaborative Arrangements and Licensing Agreements Our Revenue Sources The following are sources of revenue and when we typically recognize revenue. Commercial Revenue: SPINRAZA royalties and Licensing and other royalty revenue We earn commercial revenue primarily in the form of royalty payments on net sales of SPINRAZA. We recognize royalty revenue, including royalties from SPINRAZA sales, in the period in which the counterparty sells the related product and recognizes the related revenue, which in certain cases may require us to estimate our royalty revenue Commercial Revenue: TEGSEDI and WAYLIVRA revenue, net In January 2021 and April 2021, we entered into distribution agreements with Swedish Orphan Biovitrum AB, or Sobi, in which Sobi began commercializing TEGSEDI and WAYLIVRA in Europe and TEGSEDI in North America, respectively. Under our agreements, we are responsible for supplying finished goods inventory to Sobi and Sobi is responsible for selling each medicine to the end customer. As a result of these agreements, we earn a distribution fee on net sales from Sobi for each medicine. Under our collaboration agreement with PTC Therapeutics International Limited, or PTC, PTC is responsible for commercializing TEGSEDI and WAYLIVRA in Latin America and Caribbean countries. Under our agreement, we started receiving royalties from PTC for TEGSEDI sales in December 2021. Prior to the second quarter of 2021 in North America, we sold TEGSEDI through exclusive distribution agreements with third-party logistics companies, or 3PLs, that took title to TEGSEDI. The 3PLs then distributed TEGSEDI to a specialty pharmacy and a specialty distributor, which we collectively refer to as wholesalers, who then distributed TEGSEDI to health care providers and patients. In the United States, or U.S., we had a single 3PL as our sole customer and in Canada we also had a single 3PL as our sole customer. Prior to 2021 in Europe, we sold TEGSEDI and WAYLIVRA to hospitals and pharmacies, which were our customers, using 3PLs as distributors. Under our distribution agreements with Sobi we concluded that our performance obligation is to provide services to Sobi over the term of the agreement, which includes supplying finished goods inventory to Sobi. We are also responsible for maintaining the marketing authorization for TEGSEDI and WAYLIVRA in major markets and for leading the global commercial strategy for each medicine. We view this performance obligation as a series of distinct activities that are substantially the same. Therefore, we recognize as revenue the price Sobi pays us for the inventory when we deliver the finished goods inventory to Sobi. We also recognize distribution fee revenue based on Sobi’s net sales of TEGSEDI and WAYLIVRA. Under our agreements with Sobi, Sobi does not generally have a right of return. Prior to our distribution agreements with Sobi, we recognized TEGSEDI and WAYLIVRA commercial revenue in the period when our customer obtained control of our products, which occurred at a point in time upon transfer of title to the customer. We classified payments to customers or other parties in the distribution channel for services that were distinct and priced at fair value as selling, general and administrative, or SG&A, expenses in our consolidated statements of operations. We classified payments to customers or other parties in the distribution channel that did not meet those criteria as a reduction of revenue, as discussed further below. We excluded from revenues taxes collected from customers relating to TEGSEDI and WAYLIVRA commercial revenue and remitted these amounts to governmental authorities. Research and development revenue under collaboration agreements We enter into collaboration agreements to license and sell our technology on an exclusive or non-exclusive basis. Our collaboration agreements typically contain multiple elements, or performance obligations, including technology licenses or options to obtain technology licenses, R&D services and manufacturing services. We provide details about our collaboration agreements in Note 7, Collaborative Arrangements and Licensing Agreements Upfront payments: When we enter into a collaboration agreement and receive an upfront payment, we typically record the entire upfront payment as deferred revenue if our only performance obligation is for R&D services we will provide in the future. We amortize the upfront payment into revenue as we perform the R&D services. Milestone payments: We include additional consideration in the transaction price when it is probable. We typically include milestone payments for R&D services in the transaction price when they are achieved. We include these milestone payments when they are achieved because typically there is considerable uncertainty in the research and development processes that trigger these payments. Similarly, we include approval milestone payments in the transaction price once the medicine is approved by the applicable regulatory agency. We will recognize sales-based milestone payments in the period in which we achieve the milestone under the sales-based royalty exception allowed under accounting rules. We recognize milestone payments that relate to an ongoing performance obligation over our period of performance. For example, when we achieve a milestone payment from a partner for advancing a clinical study under a collaboration agreement, we add the milestone payment to the transaction price if the milestone relates to an ongoing R&D services performance obligation and recognize revenue related to the milestone payment over our estimated period of performance. If we have partially completed our performance obligation, then we record a cumulative-effect adjustment in the period we add the milestone to the transaction price. Conversely, we recognize in full those milestone payments that we earn based on our partners’ activities when our partner achieves the milestone event and we do not have a performance obligation. License fees: We generally recognize as revenue the total amount we determine to be the relative stand-alone selling price of a license when we deliver the license to our partner. This is because our partner has full use of the license and we do not have any additional performance obligations related to the license after delivery. Sublicense fees: We recognize sublicense fee revenue in the period in which a party, who has already licensed our technology, further licenses the technology to another party because we do not have any performance obligations related to the sublicense. Eplontersen Collaboration with AstraZeneca In December 2021, we entered into a joint development and commercialization agreement with AstraZeneca to develop and commercialize eplontersen for the treatment of transthyretin amyloidosis, or ATTR. We are jointly developing and preparing to commercialize eplontersen with AstraZeneca in the U.S. We granted AstraZeneca exclusive rights to commercialize eplontersen outside the U.S., except certain countries in Latin America. Under the terms of the agreement, we received a $200 million upfront payment in 2021. We evaluated our eplontersen collaboration under ASC 808 and identified four material components: (i) the license we granted to AstraZeneca in 2021, (ii) the co-development activities that we and AstraZeneca are performing, (iii) the co-commercialization activities that we and AstraZeneca are performing and (iv) the co-medical affairs activities that we and AstraZeneca are performing. We determined that we had a vendor-customer relationship within the scope of ASC 606 for the license we granted to AstraZeneca and as a result we had one performance obligation. For our sole performance obligation, we determined the transaction price was the $200 million upfront payment we received. We recognized the upfront payment in full in 2021 because we did not have any remaining performance obligations after we delivered the license to AstraZeneca. We also concluded that the co-development activities, the co-commercialization activities and the co-medical affairs activities are within the scope of ASC 808 because we and AstraZeneca are active participants exposed to the risks and benefits of the activities under the collaboration and therefore do not have a vendor-customer relationship. AstraZeneca is currently responsible for 55 percent of the costs associated with the ongoing global Phase 3 development program. Because we are leading the Phase 3 development program, we made an accounting policy election to recognize as non-customer revenue the cost-share funding from AstraZeneca, net of our share of AstraZeneca’s development expenses, in the same period we incur the related development expenses. As AstraZeneca is responsible for the majority of the commercial and medical affairs costs in the U.S. and all costs associated with bringing eplontersen to market outside the U.S., we made an accounting policy election to recognize cost-share funding we receive from AstraZeneca related to commercial and medical affairs activities as reductions of our SG&A expense and R&D expense, respectively. Contracts Receivable Our contracts receivable balance represents the amounts we have billed our partners or customers and that are due to us unconditionally for goods we have delivered or services we have performed. When we bill our partners or customers with payment terms based on the passage of time, we consider the contracts receivable to be unconditional. We typically receive payment within one quarter of billing our partner or customer As of December 31, 2022, approximately 82.5 percent of our contracts receivables were from one significant customer. As of December 31, 2021, approximately 93.8 percent of our contracts receivables were from two significant customers. Unbilled SPINRAZA Royalties Our unbilled SPINRAZA royalties represent our right to receive consideration from Biogen in advance of when we are eligible to bill Biogen for SPINRAZA royalties. We include these unbilled amounts in other current assets in our consolidated balance sheets. Deferred Revenue We are often entitled to bill our customers and receive payment from our customers in advance of our obligation to provide services or transfer goods to our partners. In these instances, we include the amounts in deferred revenue in our consolidated balance sheets. Cost of Sales Our cost of sales is comprised of costs related to our commercial revenue, including manufacturing costs, transportation and freight costs and indirect overhead costs associated with the manufacturing and distribution of our products. We also may include certain period costs related to manufacturing services and inventory adjustments in cost of sales. Research, Development and Patent Expenses Our research, development and patent expenses include wages, benefits, facilities, supplies, external services, clinical trial and manufacturing costs, patents and other expenses that are directly related to our research and development operations. We expense research and development costs as we incur them. When we make payments for research and development services prior to the services being rendered, we record those amounts as prepaid assets in our consolidated balance sheets and we expense them as the services are provided. A portion of the costs included in research and development expenses are costs associated with our partner agreements. In 2022, 2021 and 2020, patent expenses were $4.7 million, $5.3 million and $4.1 million, respectively. Income Taxes We account for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in our financial statements or tax returns. In addition, deferred tax assets are recorded for the future benefit of utilizing net operating losses and research and development credit carryforwards. We record a valuation allowance when necessary to reduce our net deferred tax assets to the amount expected to be realized. We apply the authoritative accounting guidance prescribing a threshold and measurement attribute for the financial recognition and measurement of a tax position taken or expected to be taken in a tax return. We recognize liabilities for uncertain tax positions based on a two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step requires us to estimate and measure the tax benefit as the largest amount that is more than 50 percent likely to be realized upon ultimate settlement. We are required to use significant judgment in evaluating our uncertain tax positions and determining our provision for income taxes. Although we believe our reserves are reasonable, we can provide no assurance that the final tax outcome of these matters will not be different from that which we have reflected in our historical income tax provisions and accruals. We adjust these reserves for changing facts and circumstances, such as the closing of a tax audit or the refinement of an estimate. To the extent that the final tax outcome of these matters is different than the amounts recorded, such differences may impact the provision for income taxes in the period in which we make such determination. We are also required to use significant judgment in determining any valuation allowance recorded against our deferred tax assets. In assessing the need for a valuation allowance, we consider all available evidence, including scheduled reversal of deferred tax liabilities, past operating results, the feasibility of tax planning strategies and estimates of future taxable income. We base our estimates of future taxable income on assumptions that are consistent with our plans. The assumptions we use represent our best estimates and involve inherent uncertainties and the application of our judgment. Should actual amounts differ from our estimates, the amount of our tax expense and liabilities we recognize could be materially impacted. We record a valuation allowance to reduce the balance of our net deferred tax assets to the amount we believe is more-likely-than-not to be realized. We do not provide for a U.S. income tax liability and foreign withholding taxes on undistributed foreign earnings of our foreign subsidiaries. Basic and Diluted Net Loss per Share Basic net loss per share We compute basic net loss per share by dividing the total net loss attributable to our common stockholders by our weighted-average number of common shares outstanding during the period. For the years ended December 31, 2022 and 2021, we did not have to consider Akcea results separately in our calculation because we owned 100 percent of Akcea for the entire period. Our basic net loss per share for the years ended December 31, 2022 and 2021 was $1.90 and $0.20, respectively. For the year ended December 31, 2020, we calculated total net loss attributable to our common stockholders using our net loss for Ionis on a stand-alone basis plus our share of Akcea’s net loss for the period. To calculate the portion of Akcea’s net loss attributable to our ownership, we multiplied Akcea’s net loss per share by the weighted average shares we owned in Akcea. As a result of this calculation, our total net loss available to Ionis common stockholders for the calculation of net loss per share was different than net loss attributable to Ionis Pharmaceuticals, Inc. common stockholders in our consolidated statements of operations. We calculated our basic net loss per share for the year ended December 31, 2020 as follows (in thousands, except per share amounts): Year Ended December 31, 2020 Weighted Average Shares Owned in Akcea Akcea s Net Loss Per Share Basic Net Loss Per Share Calculation Akcea’s net loss in the pre-merger period attributable to our ownership 77,095 $ (1.45 ) $ (111,775 ) Akcea’s net loss in the post-merger period attributable to our ownership (85,987 ) Akcea’s total net loss attributable to our ownership $ (197,762 ) Ionis’ stand-alone net loss (246,702 ) Net loss available to Ionis common stockholders $ (444,464 ) Weighted average shares outstanding 139,612 Basic net loss per share $ (3.18 ) Diluted net loss per share For the years ended December 31, 2022, 2021 and 2020, we incurred a net loss; therefore, we did not include dilutive common equivalent shares in the computation of diluted net loss per share because the effect would have been anti-dilutive. Common stock underlying the following would have had an anti-dilutive effect on net loss per share: ● 0.125 percent convertible senior notes, or Notes; ● Note hedges related to the Notes; ● 1 percent convertible senior notes, or Notes; ● Dilutive stock options; ● Unvested restricted stock units, or RSUs; ● Unvested performance restricted stock units, or PRSUs; and ● Employee Stock Purchase Plan, or ESPP. For the years ended December 31, 2022 and 2021, common stock underlying the following would also have had an anti-dilutive effect on net loss per share: ● 0 percent convertible senior notes, or Notes; and ● Note hedges related to the Notes. Additionally as of December 31, 2022 and 2021, we had warrants related to our 0 percent and 0.125 percent Notes outstanding. We will include the shares issuable under these warrants in our calculation of diluted earnings per share when the average market price per share of our common stock for the reporting period exceeds the strike price of the warrants. Stock-Based Compensation Expense 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 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 recognize compensation expense for stock options granted, 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. Stock Options and Stock Purchase Rights: We use the Black-Scholes model to estimate the fair value of stock options granted and stock purchase rights under our ESPP. 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 vol |

Investments | 2. Investments The following table summarizes the contract maturity of the available-for-sale securities we held as of December 31, 2022: One year 70 % After one year two years 28 % After two years three and a half years 2 % Total 100 % As illustrated above, at December 31, 2022, 98 percent of our available-for-sale securities had a maturity of less than two years. All of our available-for-sale securities are available to us for use in our current operations. As a result, we 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. At December 31, 2022, we had an ownership interest of less than 20 percent . The following is a summary of our investments (in thousands): Amortized Gross Unrealized Estimated December 31, 2022 Cost Gains Losses Fair Value Available-for-sale securities: Corporate debt securities (1) $ 513,790 $ 23 $ (4,365 ) $ 509,448 Debt securities issued by U.S. government agencies 133,585 — (1,829 ) 131,756 Debt securities issued by the U.S. Treasury (1) 512,655 23 (5,124 ) 507,554 Debt securities issued by states of the U.S. and political subdivisions of the states 57,484 18 (686 ) 56,816 Other municipal debt securities 6,008 — (14 ) 5,994 Total securities with a maturity of one year or less 1,223,522 64 (12,018 ) 1,211,568 Corporate debt securities 227,631 14 (10,143 ) 217,502 Debt securities issued by U.S. government agencies 34,339 — (1,040 ) 33,299 Debt securities issued by the U.S. Treasury 245,030 — (4,109 ) 240,921 Debt securities issued by states of the U.S. and political subdivisions of the states 18,314 116 (329 ) 18,101 Total securities with a maturity of more than one year 525,314 130 (15,621 ) 509,823 Total available-for-sale securities $ 1,748,836 $ 194 $ (27,639 ) $ 1,721,391 Equity securities: Total equity securities included in other current assets (2) $ 11,897 $ — $ (1,358 ) $ 10,539 Total equity securities included in deposits and other assets (3) 23,115 17,257 — 40,372 Total equity securities $ 35,012 $ 17,257 $ (1,358 ) $ 50,911 Total available-for-sale and equity securities $ 1,783,848 $ 17,451 $ (28,997 ) $ 1,772,302 Amortized Gross Unrealized Estimated December 31, 2021 Cost Gains Losses Fair Value Available-for-sale securities: Corporate debt securities (1) $ 383,870 $ 728 $ (226 ) $ 384,372 Debt securities issued by U.S. government agencies 48,493 19 (18 ) 48,494 Debt securities issued by the U.S. Treasury (1) 45,424 — (64 ) 45,360 Debt securities issued by states of the U.S. and political subdivisions of the states 134,770 45 (37 ) 134,778 Total securities with a maturity of one year or less 612,557 792 (345 ) 613,004 Corporate debt securities 382,000 331 (2,644 ) 379,687 Debt securities issued by U.S. government agencies 72,935 — (561 ) 72,374 Debt securities issued by the U.S. Treasury 137,635 139 (500 ) 137,274 Debt securities issued by states of the U.S. and political subdivisions of the states 39,909 1 (224 ) 39,686 Other municipal debt securities 6,136 — (37 ) 6,099 Total securities with a maturity of more than one year 638,615 471 (3,966 ) 635,120 Total available-for-sale securities $ 1,251,172 $ 1,263 $ (4,311 ) $ 1,248,124 Equity securities: Total equity securities included in other current assets (2) $ 11,897 $ 7,145 $ (837 ) $ 18,205 Total equity securities included in deposits and other assets (3) 15,615 16,707 — 32,322 Total equity securities $ 27,512 $ 23,852 $ (837 ) $ 50,527 Total available-for-sale and equity securities $ 1,278,684 $ 25,115 $ (5,148 ) $ 1,298,651 ________________ (1) Includes investments classified as cash equivalents in our consolidated balance sheets. (2) Our equity securities included in other current assets consisted of our investments in publicly traded companies. We recognize publicly traded equity securities at fair value. In the year ended December 31, 2022, we recognized a $7.7 million unrealized non-cash loss in our consolidated statements of operations related to a decrease in the fair value of our investments in publicly traded companies. (3) Our equity securities included in deposits and other assets consisted of our investments in privately held companies. We recognize our private company equity securities at in our consolidated balance sheets. The following is a summary of our investments we considered to be temporarily impaired at (in thousands). All of these investments have less than 12 months of temporary impairment. 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. We believe it is more likely than not that we will be able to hold our debt securities to maturity. Therefore, we anticipate full recovery of our debt securities’ amortized cost basis at maturity.

Fair Value Measurements [Abstract] | |
Fair Value Measurements | 3. Fair Value Measurements We use a three-tier fair value hierarchy to prioritize the inputs used in our fair value measurements. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets for identical assets, which includes our money market funds and treasury securities classified as available-for-sale securities and our investment in equity securities in publicly traded biotechnology companies; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable, which includes our fixed income securities and commercial paper classified as available-for-sale securities; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring us to develop our own assumptions. We classify most of our securities as Level 2. We obtain the fair value of our Level 2 investments from our custodian bank or from a professional pricing service. We validate the fair value of our Level 2 investments by understanding the pricing model used by the custodian banks or professional pricing service provider and comparing that fair value to the fair value based on observable market prices. The following tables present the major security types we held at December 31, 2022 and 2021 that we regularly measure and carry at fair value At December 31, 2022 Quoted Prices in Active Markets (Level 1) Significant Other Observable Inputs (Level 2) Cash equivalents (1) $ 211,655 $ 211,655 $ — Corporate debt securities (3) 726,950 — 726,950 Debt securities issued by U.S. government agencies (2) 165,055 — 165,055 Debt securities issued by the U.S. Treasury (2) 748,475 748,475 — Debt securities issued by states of the U.S. and political subdivisions of the states (2) 74,917 — 74,917 Other municipal debt securities (2) 5,994 — 5,994 Publicly traded equity securities included in other current assets (4) 10,539 10,539 — Total $ 1,943,585 $ 970,669 $ 972,916 At December 31, 2021 Quoted Prices in Active Markets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Cash equivalents (1) $ 541,199 $ 541,199 $ — $ — Corporate debt securities (2) 764,059 — 764,059 — Debt securities issued by U.S. government agencies (2) 120,868 — 120,868 — Debt securities issued by the U.S. Treasury (2) 182,634 182,634 — — Debt securities issued by states of the U.S. and political subdivisions of the states (5) 174,464 — 174,464 — Other municipal debt securities (2) 6,099 — 6,099 — Publicly traded equity securities included in other current assets (4) 18,205 3,875 — 14,330 Total $ 1,807,528 $ 727,708 $ 1,065,490 $ 14,330 ________________ (1) Included in cash and cash equivalents in our consolidated balance sheets.

Convertible Notes Our 0.125% Notes and 0% Notes had a fair value of $498.9 million and $587.3 million at December 31, 2022, respectively. We determine the fair value of our notes based on quoted market prices for these notes, which are Level 2 measurements because the notes do not trade regularly. |

Long-Term Obligations and Commitments | 4. Long-Term Obligations and Commitments The carrying value of our long-term obligations was as follows (in thousands): December 31, 2022 2021 0 percent $ 622,242 $ 619,119 0.125 percent 544,504 542,314 Lease liabilities 186,156 22,058 Mortgage debt 8,998 60,054 Other obligations 7,295 7,505 Total $ 1,369,195 $ 1,251,050 Less: current portion (7,535 ) (3,526 ) Total Long-Term Obligations $ 1,361,660 $ 1,247,524 Convertible Debt and Call Spread 0 Percent Convertible Senior Notes and Call Spread In April 2021, we completed a $632.5 million offering of convertible senior notes. We used a portion of the net proceeds from the issuance of the 0% Notes to repurchase $247.9 million in principal of our 1% Notes for $257.0 million. At December 31, 2022, we had the following 0% Notes outstanding (in millions except interest rate and price per share data): 0% Notes Outstanding principal balance $ 632.5 Unamortized debt issuance costs $ 10.3 Maturity date April 2026 Interest rate 0 percent Effective interest rate 0.5 percent Conversion price per share $ 57.84 Effective conversion price per share with call spread $ 76.39 Total shares of common stock subject to conversion 10.9 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 0% Notes by increasing the effective conversion price on our 0% Notes. We increased our effective conversion price to $76.39 with the same number of underlying shares as our 0% 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 0% Notes, our note hedges are subject to adjustment. Additionally, our note hedges are exercisable upon conversion of the 0% Notes. The note hedges will expire upon maturity of the 0% Notes, or April 2026. The note hedges and warrants are separate transactions and are not part of the terms of our 0% Notes. The holders of the 0% Notes do not have any rights with respect to the note hedges and warrants. 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 consolidated balance sheets. Refer to Part IV, Item 15, Note 1, Organization and Significant Accounting Policies 0.125 Percent Convertible Senior Notes and Call Spread 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. At December 31, 2022, we had the following 0.125% Notes outstanding with interest payable semi-annually (in millions except interest rate and price per share data): 0.125% Notes Outstanding principal balance $ 548.8 Unamortized debt issuance costs $ 4.3 Maturity date December 2024 Interest rate 0.125 percent Effective interest rate 0.5 percent Conversion price per share $ 83.28 Effective conversion price per share with call spread $ 123.38 Total shares of common stock subject to conversion 6.6 In conjunction with the issuance of our Notes in December 2019, 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 . We increased our effective conversion price to $ with the same number of underlying shares as our Notes. The call spread cost us $ million, of which $ million was for the note hedge purchase, offset by $ million we received for selling the warrants. Similar to our , our note hedges are subject to adjustment. Additionally, our note hedges are exercisable upon conversion of the . The note hedges will expire upon maturity of the , or December 2024. The note hedges and warrants are separate transactions and are not part of the terms of our . The holders of the do not have any rights with respect to the note hedges and warrants. 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 consolidated balance sheets. Refer to Part IV, Item 15, Note 1, Organization and Significant Accounting Policies 1 Percent Convertible Senior Notes In April 2021, we repurchased $247.9 million in aggregate principal amount of our 1% Notes in privately negotiated transactions. As a result of the repurchase, we recognized an $8.6 million loss on early retirement of debt in the second quarter of 2021, reflecting the early retirement of a significant portion of our 1% Notes. The loss on the early retirement of our debt is the difference between the amount paid to retire our 1% Notes and the net carrying balance of the liability at the time that we retired the debt. We paid the remaining principal balance of our 1% Notes with $62.0 million of cash at maturity in November 2021. Other Terms of Convertible Senior Notes The 0% and 0.125% Notes are convertible under certain conditions, at the 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 100 percent of the principal amount of the notes to be purchased, plus any accrued and unpaid interest. The 1% Notes were subject to similar terms. Our total interest expense for our outstanding senior convertible notes for the years ended December 31, 2022, 2021 and 2020 included $5.3 million, $4.9 million and $3.2 million, respectively, of non-cash interest expense related to the amortization of debt issuance costs for our convertible notes. Financing Arrangements Operating Facilities In July 2017, we purchased the building that houses our primary R&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 primary R&D facility mortgage had an interest rate of 3.88 percent. Our manufacturing facility mortgage has an interest rate of 4.20 percent. During the first five years of both mortgages, we were only required to make interest payments. We began making principal payments in 2022. Our manufacturing facility mortgage matures in August 2027. We repaid our primary R&D facility mortgage in October 2022 in conjunction with a sale and leaseback transaction. 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&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 outstanding mortgage debt on our primary R&D facility of $51.3 million. Debt Maturity Schedules Annual convertible and mortgage debt maturities, including fixed and determinable interest, at December 31, 2022 are as follows (in thousands): 2023 $ 1,281 2024 550,107 2025 595 2026 633,095 2027 447 Thereafter 8,708 Total debt and mortgage maturities $ 1,194,233 Less: Current portion included in other current liabilities (151 ) Less: Fixed and determinable interest (3,526 ) Less: Debt issuance costs (14,831 ) Total long-term debt $ 1,175,725 Royalty Revenue Monetization 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 agreements 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 for lipoprotein(a), or Lp(a), driven cardiovascular disease. Royalty Pharma’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. We will begin accounting for the royalty monetization agreement in the first quarter of 2023. |
Long-Term Obligations and Commitments | Operating Leases Carlsbad Leases We lease a facility adjacent to our manufacturing facility that has laboratory and office space that we use to support our manufacturing facility. We lease this space under a non-cancelable operating lease. In May 2020, we exercised our option to extend our lease, extending our lease term from June 2021 to August 2026. We have one remaining option to extend the lease for an additional five-year period. We also lease additional office spaces in Carlsbad. We lease these spaces under non-cancelable operating leases. In September 2022, we exercised our option to extend one of these leases, extending our term from January 2023 to May 2027. We have no remaining options to extend this lease. Our other office space lease in Carlsbad has an initial term ending in 2023. As discussed above in the section titled, Financing Arrangements Oceanside Lease 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 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’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’s construction is complete and we are able to begin constructing tenant improvements. Boston Leases We entered into an operating lease agreement for office space located in Boston, Massachusetts which commenced in August 2018. We are leasing this space under a non-cancelable operating lease with an initial term ending after 123 months and an option to extend the lease for an additional five-year term. Under the lease agreement, we received a three-month free rent period. In January 2022, we entered into a sublease agreement for our office space located in Boston, Massachusetts. The sublease commencement date was in January 2022 when the office space was ready for our tenant’s occupancy. We are subleasing this space under a non-cancelable operating sublease with a sublease term ending 83 months following the sublease commencement date with no option to extend the sublease. Under the sublease agreement we provided a seven-month free rent period, which commenced on January 6, 2022. We will receive lease payments over the sublease term totaling $9.6 million. We entered into an operating lease agreement for another office space located in Boston, Massachusetts which commenced in November 2021. We are leasing this space under a non-cancelable operating lease with an initial term ending 91 months following the lease commencement date and an option to extend the lease for an When we determined our lease term for our operating lease right-of-use assets and lease liabilities for these leases, we did not include the extension options for these leases in the original lease term because it was not reasonably certain we would exercise those extension options. Amounts related to our operating leases were as follows (dollar amounts in millions): At December 31, 2022 Right-of-use operating lease assets $ 181.5 Operating lease liabilities $ 186.2 Weighted average remaining lease term 13.8 years Weighted average discount rate 6.9 % During the years ended December 31, 2022, 2021, and 2020 we paid $4.0 million, $3.3 million and $3.8 million of lease payments, which were included in operating activities in our consolidated statements of cash flows.

Stockholders' Equity [Abstract] | |
Stockholders' Equity | 5. Stockholders Equity Preferred Stock We are authorized to issue up to 15 million shares of “blank check” Preferred Stock. As of December 31, 2022, there were no shares of Preferred Stock outstanding. We have designated Series C Junior Participating Preferred Stock but have no issued or outstanding shares as of December 31, 2022. Common Stock At December 31, 2022 and 2021, we had 300 million shares of common stock authorized, of which 142.1 million and 141.2 million were issued and outstanding, respectively. As of December 31, 2022, total common shares reserved for future issuance were 43.2 million. During the years ended December 31, 2022, 2021 and 2020, we issued 1.2 million, 1.1 million and 1.7 million shares of common stock, respectively, for stock option exercises, vesting of restricted stock units, and ESPP purchases. We received net proceeds from these transactions of $6.4 million, $11.6 million and $52.0 million in 2022, 2021 and 2020, respectively. Share Repurchase Program In September 2019, our board of directors approved a share repurchase program of up to $125 million of our common stock. In 2019, we repurchased 535,000 shares for $34.4 million. In the first quarter of 2020, we repurchased an additional 1.5 million shares for $90.5 million. Stock Plans 1989 Stock Option Plan In June 1989, our Board of Directors adopted, and the stockholders subsequently approved, a stock option plan that, as amended, provides for the issuance of non-qualified and incentive stock options for the purchase of up to 20.0 million shares of common stock to our employees, directors, and consultants. The plan expires in January 2024. The 1989 Plan does not allow us to grant stock bonuses or restricted stock awards and prohibits us from repricing any options outstanding under the plan unless our stockholders approve the repricing. Options vest over a four-year period, with 25percent exercisable at the end of one year from the date of the grant and the balance vesting ratably, on a monthly basis, thereafter and have a term of seven years. At December 31, 2022, a total of 12 thousand options were outstanding, of which options to purchase 12 thousand shares were exercisable, and 65 thousand shares were available for future grant under the 1989 Plan. 2011 Equity Incentive Plan In March 2011, our Board of Directors adopted, and the stockholders subsequently approved, a stock option plan that provides for the issuance of stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards, and performance cash awards to our employees, directors, and consultants. In June 2015, May 2017 and June 2019, after receiving approval from our stockholders, we amended our 2011 Equity Incentive Plan, or 2011 Plan, 2011 Plan. The amendment increased the total number of shares of common stock authorized for issuance under the 2011 Plan from million to million and added a fungible share counting ratio whereby the share reserve will be reduced by shares for each share of common stock issued pursuant to a full value award (i.e., RSU or PRSU) and increased by shares for each share of common stock returning from a full value award. Under the 2011 Plan, we may issue a stock award with additional acceleration of vesting and exercisability upon or after a change in control. In the absence of such provisions, no such acceleration will occur. In addition, we implemented a change of control and severance benefit plan that provides for change of control and severance benefits to our executive officers, including our chief executive officer and chief financial officer, and vice presidents. If one of our executive officers or vice presidents is terminated or resigns for good reason during the period that begins three months before and ends twelve months following a change in control of the company, the impacted employee’s stock options and RSUs vesting will accelerate for options and RSUs outstanding as of the termination date. 2020 Equity Incentive Plan In connection with the Akcea Merger in October 2020, we assumed the unallocated portion of the available share reserve under the Akcea 2015 Equity Incentive Plan. In December 2020, we amended and restated the Akcea 2015 equity plan, including renaming the plan as the Ionis Pharmaceuticals, Inc. 2020 Equity Incentive Plan, or 2020 Plan. The 2020 Plan provided for the issuance of up to million shares of our Common Stock to our employees, directors and consultants who were employees of Akcea prior to the Akcea Merger. In the second quarter of 2021, our Compensation Committee approved an amendment to the 2020 Plan. The amendment decreased the total number of shares of common stock authorized for issuance under the 2020 Plan from approximately million to million. We assumed the 2020 Plan in connection with Ionis’ reacquisition of all of the outstanding shares of Akcea Therapeutics, Inc. as part of the Akcea Merger. The plan expires in December 2025. The 2020 Plan does not allow us to reduce the exercise price of any outstanding stock options or stock appreciation rights or cancel any outstanding stock options or stock appreciation rights that have an exercise price or strike price greater than the current fair market value of the common stock in exchange for cash or other stock awards unless our stockholders approve such action. Currently we anticipate awarding only stock options and RSU awards to our eligible employees, directors and consultants. Options vest over a four-year period, with 25 percent exercisable at the end of one year from the date of the grant and the balance vesting ratably, on a monthly basis, thereafter and have a term of seven years. Options granted after December 31, 2021 have a term of ten years. We have granted restricted stock unit awards to our employees under the 2020 Plan which vest annually over a four-year period. At December 31, 2022, a total of 0.3 million options were outstanding, of which 61 thousand were exercisable, 0.1 million restricted stock unit awards were outstanding, and 1.2 million shares were available for future grant under the 2020 Plan. Under the 2020 Plan, we may issue a stock award with additional acceleration of vesting and exercisability upon or after a change in control. In the absence of such provisions, no such acceleration will occur. Corporate Transactions and Change in Control under 2011 and 2020 Plans In the event of certain significant corporate transactions, our Board of Directors has the discretion to take one or more of the following actions with respect to outstanding stock awards under the 2011 and 2020 Plans: ● arrange for assumption, continuation, or substitution of a stock award by a surviving or acquiring entity (or its parent company); ● arrange for the assignment of any reacquisition or repurchase rights applicable to any shares of our common stock issued pursuant to a stock award to the surviving or acquiring corporation (or its parent company); ● accelerate the vesting and exercisability of a stock award followed by the termination of the stock award; ● arrange for the lapse of any reacquisition or repurchase rights applicable to any shares of our common stock issued pursuant to a stock award; ● cancel or arrange for the cancellation of a stock award, to the extent not vested or not exercised prior to the effective date of the corporate transaction, in exchange for cash consideration, if any, as the Board, in its sole discretion, may consider appropriate; and ● arrange for the surrender of a stock award in exchange for a payment equal to the excess of (a) the value of the property the holder of the stock award would have received upon the exercise of the stock award, over (b) any exercise price payable by such holder in connection with such exercise. 2002 Non-Employee Directors’ Stock Option Plan In September 2001, our Board of Directors adopted, and the stockholders subsequently approved, an amendment and restatement of the 1992 Non-Employee Directors’ Stock Option Plan, which provides for the issuance of non-qualified stock options and restricted stock units to our non-employee directors. The name of the resulting plan is the 2002 Non-Employee Directors’ Stock Option Plan, or the 2002 Plan. In June 2015, after receiving approval from our stockholders, we amended our 2002 Plan to increase the total number of shares reserved for issuance from 1.2 million to 2.0 million. In June 2020, after receiving approval from our stockholders, we further amended our 2002 Plan. The amendments included: ● An increase to the total number of shares reserved for issuance under the plan from million to million shares; ● A reduction to the amount of the automatic awards under the plan; ● A revision to the vesting schedule of new awards granted; and ● An extension of the term of the plan. Options under this plan expire 10 years from the date of grant. At December 31, 2022, a total of 0.9 million options were outstanding, of which 0.8 million were exercisable, 0.1 million restricted stock unit awards were outstanding, and 0.6 million shares were available for future grant under the 2002 Plan. Employee Stock Purchase Plan In June 2009, our Board of Directors adopted, and the stockholders subsequently approved, the amendment and restatement of the ESPP and we reserved an additional 150,000 shares of common stock for issuance thereunder. In each of the subsequent years until 2019, we reserved an additional 150,000 shares of common stock for the ESPP resulting in a total of 3.2 million shares authorized under the plan as of December 31, 2022. The ESPP permits full-time employees to purchase common stock through payroll deductions (which cannot exceed 10percent of each employee’s compensation) at the lower of 85percent of fair market value at the beginning of the purchase period or the end of each purchase period. Under the amended and restated ESPP, employees must hold the stock they purchase for a minimum of six months from the date of purchase. During 2022, employees purchased and we issued to employees 0.1 million shares under the ESPP at a weighted average price of $28.57 per share. At December 31, 2022, there were 0.5 million shares available for purchase under the ESPP. Stock Option Activity The following table summarizes the stock option activity under our stock plans for the year ended December 31, 2022 (in thousands, except per share and contractual life data): Number of Shares Weighted Average Exercise Price Per Share Average Remaining Contractual Term (Years) Aggregate Intrinsic Value Outstanding at December 31, 2021 14,089 $ 54.04 Granted 2,864 $ 34.78 Exercised (123 ) $ 29.35 Cancelled/forfeited/expired (1,860 ) $ 53.96 Outstanding at December 31, 2022 14,970 $ 50.57 4.01 $ 12,243 Exercisable at December 31, 2022 10,285 $ 53.74 2.56 $ 1,651 The weighted-average estimated fair values of options granted were $18.66, $24.35 and $29.43 for the years ended December 31, 2022, 2021 and 2020, respectively. The total intrinsic value of options exercised during the years ended December 31, 2022, 2021 and 2020 were $1.4 million, $2.5 million and $15.5 million, respectively, which we determined as of the date of exercise. The amount of cash received from the exercise of stock options was $3.6 million, $8.5 million and $43.7 million for the years ended December 31, 2022, 2021 and 2020, respectively. For the year ended December 31, 2022, the weighted-average fair value of options exercised was $40.71. As of December 31, 2022, total unrecognized compensation cost related to non-vested stock options was $41.1 million. We expect to recognize this cost over a weighted average period of 1.1 years.

Significant components of our deferred tax assets and liabilities as of December 31, 2022 and 2021 are as follows (in thousands): Year Ended December 31, 2022 2021 Deferred Tax Assets: Net operating loss carryovers $ 87,802 $ 85,600 Tax credits 277,436 269,538 Deferred revenue 85,700 104,330 Stock-based compensation 86,983 86,611 Intangible and capital assets 104,649 92,542 Convertible debt 34,384 45,681 Interest expense limitation — 6,996 Capitalized research and development expenses 119,635 — Long-term lease liabilities 45,612 5,119 Other 15,813 9,929 Total deferred tax assets $ 858,014 $ 706,346 Deferred Tax Liabilities: Fixed assets (4,475 ) (3,303 ) Right-of-use assets (44,504 ) (4,159 ) Other (313 ) (1,111 ) Net deferred tax asset $ 808,722 $ 697,773 Valuation allowance (808,722 ) (697,773 ) Total net deferred tax assets and liabilities $ — $ — We evaluate our deferred tax assets regularly to determine whether adjustments to the valuation allowance are appropriate due to changes in facts or circumstances, such as changes in expected future pre-tax earnings, tax law, interactions with taxing authorities and developments in case law. In making this evaluation, we rely on our recent history of pre-tax earnings. Our material assumptions are our forecasts of future pre-tax earnings and the nature and timing of future deductions and income represented by the deferred tax assets and liabilities, all of which involve the exercise of significant judgment. Although we believe our estimates are reasonable, we are required to use significant judgment in determining the appropriate amount of valuation allowance recorded against our deferred tax assets. Our valuation allowance increased by $111 million from December 31, 2021 to December 31, 2022. The increase was primarily related to increases in our deferred tax asset for capitalized research and development expenses. At December 31, 2022, we had federal and state, primarily California, tax net operating loss carryforwards of $242.8 million and $461.3 million, respectively. Our federal tax loss carryforwards are available indefinitely. Our California tax loss carryforwards will begin to expire in 2031. At December 31, 2022, we also had federal and California research and development tax credit carryforwards of $224.9 million and $110.7 million, respectively. Our federal research and development tax credit carryforwards will begin to expire in 2035. Our California research and development tax credit carryforwards are available indefinitely. Utilization of the net operating loss and tax credit carryforwards may be subject to an annual limitation due to the ownership change limitations provided by the Internal Revenue Code of 1986, as amended, and similar state provisions. The annual limitation may result in the expiration of net operating losses and credits before utilization. We analyze filing positions in all U.S. federal, state and foreign jurisdictions where we file income tax returns, and all open tax years in these jurisdictions to determine if we have any uncertain tax positions on any of our income tax returns. We recognize the impact of an uncertain tax position on an income tax return at the largest amount that the relevant taxing authority is more-likely-than not to sustain upon audit. We do not recognize uncertain income tax positions if they have less than 50 percent likelihood of the applicable tax authority sustaining our position. The following table summarizes our gross unrecognized tax benefits (in thousands): Year Ended December 31, 2022 2021 2020 Beginning balance of unrecognized tax benefits $ 55,085 $ 54,163 $ 69,784 Decrease for prior period tax positions (267 ) (695 ) (24,154 ) Increase for prior period tax positions 259 263 7,023 Increase for current period tax positions 1,490 1,354 1,510 Ending balance of unrecognized tax benefits $ 56,567 $ 55,085 $ 54,163 Included in the balance of unrecognized tax benefits at December 31, 2022, 2021 and 2020 was $6.2 million, $6.2 million and $6.4 million respectively, that if we recognized, could impact our effective tax rate, subject to our remaining valuation allowance. We estimate that it is reasonably possible that the balance of our gross unrecognized tax benefits may decrease by approximately $15.0 million within the next 12 months due to the lapse of statute of limitations on underlying tax positions primarily related to tax credits. We recognize interest and/or penalties related to income tax matters in income tax expense. During the years ended December 31, 2022, 2021 and 2020, we recognized $0.8 million, $0.5 million and $0.3 million, respectively, of accrued interest and penalties related to gross unrecognized tax benefits. We are subject to taxation in the U.S. and various state and foreign jurisdictions. The tax years 2018 through 2021 remain open to examination by major taxing jurisdictions, primarily federal and California, although net operating loss and credit carryforwards generated prior to 2018 may still be adjusted upon examination by the Internal Revenue Service or state tax authorities if they have been used in an open period or are used in a future period. We do not provide for a U.S. income tax liability and foreign withholding taxes on undistributed foreign earnings of our foreign subsidiaries as we consider those earnings to be permanently reinvested. It is not practicable for us to calculate the amount of unrecognized deferred tax liabilities associated with these earnings |

Collaborative Arrangements and Licensing Agreements [Abstract] | |
Collaborative Arrangements and Licensing Agreements | 7. Collaborative Arrangements and Licensing Agreements Strategic Partnership Biogen We have several strategic collaborations with Biogen focused on using antisense technology to advance the treatment of neurological disorders. These collaborations combine our expertise in creating antisense medicines with Biogen’s expertise in developing therapies for neurological disorders. We developed and licensed to Biogen SPINRAZA, our approved medicine to treat people with spinal muscular atrophy, or SMA. We and Biogen are currently developing numerous investigational medicines to treat neurodegenerative diseases under these collaborations, including medicines in development to treat people with ALS, SMA, AS, AD Spinal Muscular Atrophy Collaborations SPINRAZA In January 2012, we entered into a collaboration agreement with Biogen to develop and commercialize SPINRAZA. From inception through , we earned more than $ billion in total revenue under our SPINRAZA collaboration, including more than $ billion in revenue from SPINRAZA royalties and more than $ million in R&D revenue. We are receiving tiered royalties ranging from to on net sales of SPINRAZA. We have exclusively in-licensed patents related to SPINRAZA from Cold Spring Harbor Laboratory and the University of Massachusetts. We pay Cold Spring Harbor Laboratory and the University of Massachusetts a low single digit royalty on net sales of SPINRAZA. Biogen is responsible for all global development, regulatory and commercialization activities and costs for SPINRAZA. We completed our performance obligations under our collaboration in 2016 In January 2023, we entered into a royalty purchase agreement with Royalty Pharma in which 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. Royalty Pharma’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, which Novartis is developing. Refer to Part IV, Item 15, Note 4, Long-Term Obligations and Commitments New antisense medicines for the treatment of SMA In December 2017, we entered into a collaboration agreement with Biogen to new antisense medicines for the treatment of SMA . Biogen has the option to license therapies arising out of this collaboration following the completion of preclinical studies. Upon licensing, Biogen will be responsible for global development, regulatory and commercialization activities and costs for such therapies . Under the collaboration agreement, we received a upfront payment in the fourth quarter of 2017 . In December 2021, we earned a $ million license fee payment when Biogen exercised its option to license ION306. We will receive development and regulatory milestone payments from Biogen if new medicines, including ION306, advance towards marketing approval. Over the term of the collaboration, we are eligible to receive up to $1.2 billion, which is comprised of a $25 million upfront payment, up to $110 million in license fees, up to $80 million in development milestone payments, up to $180 million in regulatory milestone payments, up to $800 million in sales milestone payments and other payments, including up to $555 million if Biogen advances ION306, which includes up to $45 million in development milestone payments, up to $110 million in regulatory milestone payments and up to $400 million in sales milestone payments. In addition, we are eligible to receive tiered royalties from the mid-teens to on net sales. for the initiation of a Phase 3 trial under this collaboration. At the commencement of this collaboration, we identified one performance obligation, which was to perform R&D services for Biogen. We determined the transaction price to be the $25 million upfront payment we received when we entered into the collaboration. We allocated the transaction price to our single performance obligation. In the fourth quarter of 2019, we completed our R&D services performance obligation under this collaboration. In the fourth quarter of 2021, we identified another performance obligation upon Biogen’s license of ION306 because the license we granted to Biogen is distinct from our other performance obligations. We recognized the $60 million license fee for ION306 as revenue at that time because Biogen had full use of the license without any continuing involvement from us. Additionally, we did not have any further performance obligations related to the license after we delivered it to Biogen. Biogen is solely responsible for the costs and expenses related to the development, manufacturing and potential future commercialization of ION306 following the option exercise. We do not have any remaining performance obligations under this collaboration. Neurology Collaborations 2018 Strategic Neurology In April 2018, we and Biogen entered into a strategic collaboration to develop novel antisense medicines for a broad range of neurological diseases and entered into a Stock Purchase Agreement, or SPA. As part of the collaboration, Biogen gained exclusive rights to the use of our antisense technology to develop therapies for these diseases for years. We are responsible for the identification of antisense drug candidates based on selected medicines Biogen will have the option to license the selected medicine If Biogen exercises its option to license a medicine, it will assume global development, regulatory and commercialization responsibilities and costs for that medicine. In the quarter of , we received Over the term of our collaboration, w e are eligible to receive up to $ million, which is comprised of a $ million license fee, up to $ million in development milestone payments and up to $ million in regulatory milestone payments for each medicine that achieves marketing approval. up to the on net sales. W under this collaboration. At the commencement of this collaboration, we considered that the collaboration agreement and SPA were negotiated concurrently and in contemplation of one another. Based on these facts and circumstances, we concluded that we should evaluate the provisions of the agreements on a combined basis. W We determined our transaction price to be $ million, comprised of $ million from the upfront payment and $ million for the premium paid by Biogen for its purchase of our common stock. From inception through December 31, 2022, we have included $616 million in payments in the transaction price for our R&D services performance obligation under this collaboration, including $ million of milestone payments we achieved in 2021 and $ million of milestone payments we achieved in 2020. These milestone payments did not create new performance obligations because they are part of our original R&D services performance obligation. Therefore, we included these amounts in our transaction price for our R&D services performance obligation in the period we achieved the milestone payment. We are recognizing revenue for our R&D services performance obligation as we perform services based on our effort to satisfy our performance obligation relative to our total effort expected to satisfy our performance obligation. We currently estimate we will satisfy our performance obligation at the end of the contractual term in June 2028. 2013 Strategic Neurology In September 2013, we and Biogen entered into a long-term strategic relationship focused on applying antisense technology to advance the treatment of neurodegenerative diseases. As part of the collaboration, Biogen gained exclusive rights to the use of our antisense technology to develop therapies for neurological diseases and has the option to license medicines resulting from this collaboration. We will usually be responsible for drug discovery and early development of antisense medicines and Biogen has the option to license antisense medicines after Phase 2 proof-of-concept. In October 2016, we expanded our collaboration to include additional research activities we will perform. If Biogen exercises its option to license a medicine, it will assume global development, regulatory and commercialization responsibilities and costs for that medicine. We are currently advancing five investigational medicines in development under this collaboration, including a a a Under the terms of the agreement, we received an upfront payment of $100 million and are eligible to receive milestone payments, license fees and royalty payments for all medicines developed under this collaboration, with the specific amounts dependent upon the modality of the molecule advanced by Biogen. Under this collaboration, we received a $35 million license fee payment when Biogen licensed tofersen from us in 2018. Over the term of the collaboration for tofersen, we are eligible to receive nearly $110 million, which is comprised of the $35 million license fee received in 2018, up to $18 million in development milestone payments and up to $55 million in regulatory milestone payments. For each of the other antisense molecules that are chosen for drug discovery and development under this collaboration, we are eligible to receive up to approximately $260 million, which is comprised of a $70 million license fee, up to $60 million in development milestone payments, including amounts related to the cost of clinical trials, and up to $130 million in regulatory milestone payments. In addition, we are eligible to receive tiered royalties up to the mid-teens on net sales from any antisense medicines developed under this collaboration. From inception through December 31, 2022, we have received more than $300 million in payments under this collaboration. We will achieve the next payment of $16 million if the FDA approves Biogen’s NDA filing of tofersen. At the commencement of our 2013 strategic neurology collaboration, we identified one performance obligation, which was to perform R&D services for Biogen. At inception, we determined the transaction price to be the $100 million upfront payment we received and allocated it to our single performance obligation. As we achieve milestone payments for our R&D services, we include these amounts in our transaction price for our R&D services performance obligation. We recognized revenue for our R&D services performance obligation based on our effort to satisfy our performance obligation relative to our total effort expected to satisfy our performance obligation . research and development services and recognized the remaining revenue related to this performance obligation. Under this collaboration, we have also generated additional payments that we concluded were not part of our R&D services performance obligation. We recognized each of these payments in full in the respective quarter we generated the payment because we did not have any performance obligations for the respective payment. For example, in the third quarter of 2022, we earned a million milestone payment when the FDA accepted Biogen’s NDA filing of tofersen, which we recognized in full because we did not have any performance obligations related to this milestone payment. 2012 Neurology In December 2012, we and Biogen entered into a collaboration agreement to develop and commercialize novel antisense medicines to treat neurodegenerative diseases. We are responsible for the development of each of the medicines through the completion of the initial Phase 2 clinical study for such medicine. Biogen has the option to license a medicine from each of the programs through the completion of the first Phase 2 study for each program. Under this collaboration, Biogen is conducting the IONIS-MAPT Rx Under the terms of the agreement, we received an upfront payment of $ million. Over the term of the collaboration, we are eligible to receive up to $ million, which is comprised of a $ million license fee, up to $ million in development milestone payments per program and up to $ million in regulatory milestone payments per program, plus a mark-up on the cost estimate of the Phase 1 and 2 studies. In addition, we are eligible to receive tiered royalties up to the mid-teens on net sales of any medicines resulting from each of the programs. From inception through , we have received nearly $ million in payments under this collaboration, including nearly $ million in milestone payments we received from Biogen for advancing ION582 and a $ million milestone payment we received from Biogen when Biogen advanced Rx during 2022. We will achieve the next payment of up to $ Under our collaboration, we determined we had a performance obligation to perform R&D services. We allocated $40 million in total payments to the transaction price for our R&D services performance obligation. In the third quarter of 2019, we completed our R&D services performance obligation when we designated a development candidate and Biogen accepted the development candidate. We recognized revenue as we performed services based on our effort to satisfy our performance obligation relative to the total effort expected to satisfy our performance obligation. When we commenced development for IONIS-MAPT Rx Rx Rx Rx In the fourth quarter of 2019, we identified another performance obligation upon Biogen’s license of IONIS-MAPT Rx Rx Rx In the fourth quarter of 2022, we achieved $ million in milestone payments when Biogen advanced ION582. for ION582. During the years ended December 31, 2022, 2021 and 2020, we earned the following revenue from our relationship with Biogen (in millions, except percentage amounts): Year Ended December 31, 2022 2021 2020 SPINRAZA royalties (commercial revenue) $ 242.3 $ 267.8 $ 286.6 R&D revenue 124.4 161.0 122.0 Total revenue from our relationship with Biogen $ 366.7 $ 428.8 $ 408.6 Percentage of total revenue 62 % 53 % 56 % Our , and included deferred revenue of $ million and $ million, respectively, related to our relationship with Biogen. Joint Development and Commercialization Arrangement AstraZeneca Eplontersen Collaboration In December 2021, we entered into a joint development and commercialization agreement with AstraZeneca to develop and commercialize eplontersen for the treatment of ATTR. We are jointly developing and preparing to commercialize eplontersen with AstraZeneca in the U.S. We granted AstraZeneca exclusive rights to commercialize eplontersen outside the U.S., except certain countries in Latin America. Over the term of the collaboration, we are eligible to receive up to $3.6 billion, which is comprised of a $200 million upfront payment, up to $485 million in development and approval milestone payments and up to $2.9 billion in sales milestone payments. The agreement also includes territory-specific development, commercial and medical affairs cost-sharing provisions. In addition, we are eligible to receive up to mid-20 percent royalties for sales in the U.S. and tiered royalties up to the high teens for sales outside the U.S. We evaluated our eplontersen collaboration under ASC 808 and identified four material components: (i) the license we granted to AstraZeneca in 2021, (ii) the co-development activities that we and AstraZeneca will perform, (iii) the co-commercialization activities that we and AstraZeneca will perform and (iv) the co-medical affairs activities that we and AstraZeneca will perform. We determined that we had a vendor-customer relationship within the scope of ASC 606 for the license we granted to AstraZeneca and as a result we had one performance obligation. For our sole performance obligation, we determined the transaction price was the $200 million upfront payment we received. We recognized the upfront payment in full in 2021 because we did not have any remaining performance obligations after we delivered the license to AstraZeneca. We also concluded that the co-development activities, the co-commercialization activities and the co-medical affairs activities are within the scope of ASC 808 because we and AstraZeneca are active participants exposed to the risks and benefits of the activities under the collaboration. AstraZeneca is currently responsible for 55 percent of the costs associated with the ongoing global Phase 3 development program. Because we are leading the Phase 3 development program, we recognize as revenue the 55 percent of cost-share funding AstraZeneca is responsible for in the same period we incur the related development expenses. As AstraZeneca is responsible for the majority of the commercial and medical affairs costs in the U.S. and all costs associated with bringing eplontersen to market outside the U.S., we recognize cost-share funding we receive from AstraZeneca related to these activities as a reduction of our commercial and medical affairs expenses. We will achieve the next payment of up to $50 million upon the first regulatory approval under this collaboration. From inception through December 31, 2022, we have received nearly $260 million in payments under this collaboration. Research and Development Partners AstraZeneca In addition to our collaboration for eplontersen, we have a collaboration with AstraZeneca focused on the treatment of cardiovascular, renal and metabolic diseases. In July 2015, we and AstraZeneca formed a collaboration to discover and develop antisense therapies for treating cardiovascular, renal and metabolic diseases. Under our collaboration, AstraZeneca has licensed multiple medicines from us, including medicines in development to treat people with ATTR amyloidosis, a genetically associated form of kidney disease and NASH Over the term of the collaboration, we are eligible to receive up to $5.8 billion, which is comprised of a $65 million upfront payment, up to $290 million in license fees, up to $1.1 billion in development milestone payments, up to $2.9 billion in regulatory milestone payments and up to $1.5 billion in sales milestone payments. In addition, we are eligible to receive tiered royalties up to the low teens on net sales from any product that AstraZeneca successfully commercializes under this collaboration agreement. We will achieve the next payment of $10 million under this collaboration if AstraZeneca advances a medicine under this collaboration . At the commencement of this collaboration, we identified one performance obligation, which was to perform R&D services for AstraZeneca. We determined the transaction price to be the $65 million upfront payment we received and we allocated it to our single performance obligation. We recognized revenue for our R&D services performance obligation as we performed services based on our effort to satisfy this performance obligation relative to our total effort expected to satisfy our performance obligation. We completed our performance obligation in Under this collaboration, we have also generated additional payments that we concluded were not part of our R&D services performance obligation. We recognized each of these payments in full in the respective quarter we generated the payment because the payments were distinct and we did not have any performance obligations for the respective payment. For example, in the fourth quarter of 2021, we earned a $30 million license fee when AstraZeneca licensed a target for a metabolic disease. We recognized the license fee as revenue at that time because AstraZeneca had full use of the license without any continuing involvement from us. Additionally, we did not have any further performance obligations related to the license after we delivered it to AstraZeneca. During the years ended December 31, 2022, 2021 and 2020, we earned the following revenue from our relationship with AstraZeneca (in millions, except percentage amounts): Year Ended December 31, 2022 2021 2020 R&D revenue $ 79.2 $ 254.6 $ 88.0 Percentage of total revenue 13 % 31 % 12 % We did not have any deferred revenue from our relationship with AstraZeneca at December 31, 2022 and 2021. GSK In March 2010, we entered into a 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 two medicines targeting hepatitis B virus, or HBV: bepirovirsen and IONIS-HBV-L Rx Over the term of the collaboration, we are eligible to receive nearly $260 million, which is comprised of a $25 million license fee, up to $42.5 million in development milestone payments, up to $120 million in regulatory milestone payments and up to $70 million in sales milestone payments if GSK successfully develops bepirovirsen. In addition, we are eligible to receive tiered royalties up to the low-teens on net sales of bepirovirsen. From inception through December 31, 2022, we have received more than $50 million in payments under the HBV program collaboration. We completed our R&D services performance obligations under our collaboration in the first quarter of 2015. We do not have any remaining performance obligations under our collaboration with GSK; however, we can still earn additional payments and royalties as GSK advances the HBV program. In January 2023, we earned a $ million milestone when GSK initiated a Phase 3 study of bepirovirsen. We will achieve the next payment of $ million if the FDA accepts an NDA filing of bepirovirsen for review. During the years ended December 31, 2022, 2021 and 2020, we earned the following revenue from our relationship with GSK (in millions, except percentage amounts): Year Ended December 31, 2022 2021 2020 R&D revenue $ — $ — $ 0.2 Percentage of total revenue — — — We did not have any deferred revenue from our relationship with GSK at December 31, 2022 and 2021. Novartis In January 2017, we initiated a collaboration with Novartis to develop and commercialize pelacarsen and olezarsen. When Novartis decided to not exercise its option for Over the term of the collaboration, we are eligible to receive up to $900 million, which is comprised of a $75 million upfront payment, a $150 million license fee, a $25 million development milestone payment, up to $290 million in regulatory milestone payments and up to $360 million in sales milestone payments. From inception through , we have received nearly $ million in payments under this collaboration. We will achieve the next payment of up to $ million if Novartis advances regulatory activities for pelacarsen. In conjunction with this collaboration, we entered into a SPA with Novartis. As part of the SPA, Novartis purchased 1.6 million shares of our common stock for $100 million in the first quarter of 2017. At the commencement of this collaboration, we identified four separate performance obligations: ● R&D services for pelacarsen; ● R&D services for olezarsen; ● API for pelacarsen; and ● API for olezarsen. We determined that the R&D services for each medicine and the API for each medicine were distinct performance obligations. We determined our transaction price to be $108.4 million, comprised of the following: ● $75 million from the upfront payment; ● $28.4 million for the premium paid by Novartis for its purchase of our common stock at a premium in the first quarter of 2017; and ● $5.0 million for the potential premium Novartis would have paid if they purchased our common stock in the future. We allocated the transaction price based on the estimated stand-alone selling price of each performance obligation as follows: ● $ million for the R&D services for pelacarsen; ● $40.1 million for the R&D services for olezarsen ● $1.5 ● $2.8 We completed our R&D services performance obligations for olezarsen and pelacarsen We recognized revenue related to the R&D services for pelacarsen and olezarsen performance obligations as we performed services . During the years ended December 31, 2022, 2021 and 2020, we earned the following revenue from our relationship with Novartis (in millions, except percentage amounts): Year Ended December 31, 2022 2021 2020 R&D revenue $ 0.2 $ 25.5 $ 1.0 Percentage of total revenue — 3 % — We did not have any deferred revenue from our relationship with Novartis at December 31, 2022 and 2021. As described in the Biogen SPINRAZA Long-Term Obligations and Commitments Roche Huntington’s Disease In April 2013, we formed an alliance with Hoffmann-La Roche Inc and F. Hoffmann-La Roche Ltd, collectively Roche, to develop treatments for HD based on our antisense technology. Under the agreement, we discovered and developed tominersen, an investigational medicine targeting HTT protein. We developed tominersen through completion of our Phase 1/2 clinical study in people with early-stage HD. In the fourth quarter of 2017, upon completion of the Phase 1/2 study, Roche exercised its option to license tominersen. Roche is responsible for all global development, regulatory and commercialization activities and costs for tominersen. Over the term of the collaboration, we are eligible to receive up to $395 million, which is comprised of a $30 million upfront payment, a $45 million license fee, up to $70 million in development milestone payments, up to $170 million in regulatory milestone payments and up to $80 million in sales milestone payments as tominersen advances. In addition, we are eligible to receive up to $136.5 million in milestone payments for each additional medicine successfully developed. We are also eligible to receive tiered royalties up to the mid-teens on net sales of any product resulting from this alliance. From inception through December 31, 2022, we have received more than $150 million in payments under this collaboration. We will achieve the next payment of $17.5 million if Roche advances a medicine under this collaboration. At the commencement of this collaboration, we identified one performance obligation, which was to perform R&D services for Roche. We determined the transaction price to be the $30 million upfront payment we received and allocated it to our single performance obligation. As we achieved milestone payments for our R&D services, we included these amounts in our transaction price for our R&D services performance obligation. We recognized revenue for our R&D services performance obligation over our period of performance, which ended in the third quarter of 2017. Under this collaboration, we have also generated additional payments that we concluded were not part of our R&D services performance obligation. We recognized each of these payments in full in the respective quarter in which we generated the payment because the payments were distinct and we did not have any performance obligations for the respective payment. In 2019, we earned $35 million in milestone payments when Roche advanced tominersen under this collaboration. In March 2021, Roche decided to discontinue dosing in the Phase 3 GENERATION HD1 study of tominersen in patients with manifest HD based on the results of a pre-planned review of data from the Phase 3 study conducted by an unblinded iDMC. In January 2023, Roche initiated the Phase 2, GENERATION HD2, study of tominersen in patients with prodromal or early manifest HD. Roche is focusing on early-stage and younger patients based on the post-hoc analyses from the GENERATION HD1 study that suggested tominersen may benefit these patient groups. We do not have any remaining performance obligations related to tominersen under this collaboration with Roche; however, we can still earn additional payments and royalties as Roche advances tominersen. IONIS-FB-L Rx for Complement-Mediated Diseases In October 2018, we entered into a collaboration agreement with Roche to develop IONIS-FB-L Rx IONIS-FB-L Rx second After positive data from a Phase 2 clinical study, licensed IONIS-FB-L Rx in July 2022 for $ million. As a result, Roche is responsible for global development, regulatory and commercialization activities, and costs for IONIS-FB-L Rx , except for the open label Phase 2 study in patients with IgAN and the Phase 2 study in patients with GA, both of which we are conducting and funding. In July 2022, we amended our IONIS-FB-L Rx collaboration agreement with Roche. The amendment changed future potential milestone payments we could receive under the collaboration. We determined there were no changes that would require adjustments to revenue we previously recognized. Over the term of the collaboration, we are eligible to receive more than $ million, which is comprised of a $ million upfront payment, a $ million license fee, up to $ million in development milestones, up to $ million in regulatory milestones and up to $ million in sales milestone payments. In addition, we are also eligible to receive tiered royalties from the high teens to on net sales. We will achieve the next payment of up to $ million if Roche advances IONIS-FB-L Rx under this collaboration. At the commencement of this collaboration, we identified one performance obligation, which was to perform R&D services for Roche. We determined the transaction price to be the $75 million upfront payment we received and allocated it to our single performance obligation. We are recognizing revenue for our R&D services performance obligation as we perform services based on our effort to satisfy our performance obligation relative to our total effort expected to satisfy our performance obligation. currently estimate we will satisfy our performance obligation in During the years ended December 31, 2022, 2021 and 2020, we earned the following revenue from our relationship with Roche (in millions, except percentage amounts): Year Ended December 31, 2022 2021 2020 R&D revenue $ 67.2 $ 17.2 $ 5.9 Percentage of total revenue 11 % 2 % 1 % Our , and included deferred revenue of $ million and $ million related to our relationship with Roche, respectively. Commercialization Partnerships Swedish Orphan Biovitrum AB (Sobi) We began commercializing TEGSEDI and WAYLIVRA in Europe in January 2021 and TEGSEDI in North America in April 2021 through distribution agreements with Sobi. Under our agreements, we are responsible for supplying finished goods inventory to Sobi and Sobi is responsible for selling each medicine to the end customer. In exchange, we earn a distribution fee on net sales from Sobi for each medicine. PTC Therapeutics In August 2018, we entered into an exclusive license agreement with PTC Therapeutics to commercialize TEGSEDI and WAYLIVRA in Latin America and certain Caribbean countries. Under the license agreement, we are eligible to receive royalties from PTC in the mid- range on net sales for each medicine. . Technology Enhancement Collaborations Bicycle License Agreement In December 2020, we entered into a collaboration agreement with Bicycle and obtained an option to license its peptide technology to potentially increase the delivery capabilities of our LICA medicines. In July 2021, we paid $42 million when we exercised our option to license Bicycle’s technology, which included an equity investment in Bicycle. As part of our stock purchase, we entered into a lockup agreement with Bicycle that restricted our ability to trade our Bicycle shares for one year. In 2021, we recorded a $7.2 million equity investment for the shares we received in Bicycle. We recognized the remaining $34.8 million as R&D expense in 2021. From inception through December 31, 2022, we have paid Bicycle $46.6 million under this collaboration agreement. Metagenomi License Agreement In November 2022, we entered into a collaboration and license agreement with Metagenomi to research, develop and commercialize investigational medicines for up to four initial genetic targets, and, upon the achievement of certain development milestones, four additional genetic targets using gene editing technologies. As a result, we paid $80 million to license Metagenomi’s technologies. We recorded the $80 million payment as R&D expense in 2022 upon receiving a license from Metagenomi for intellectual property that is in research with no current alternate use. We will also pay Metagenomi certain fees for the selection of genetic targets, and contingent on the achievement of certain development, regulatory and sales events, milestone payments and royalties. In addition, we will reimburse Metagenomi for certain of its costs in conducting its research and drug discovery activities under the collaboration. Other Agreements Alnylam Pharmaceuticals, Inc. Under the terms of our agreement with Alnylam, we co-exclusively (with ourselves) licensed to Alnylam our patent estate relating to antisense motifs and mechanisms and oligonucleotide chemistry for double-stranded RNAi thera |

Legal Proceedings | 9. Legal Proceedings 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. On August 5, 2021, purported former stockholders of Akcea filed an action in the Delaware Court of Chancery captioned John Makris, et al. v. Ionis Pharmaceuticals, Inc., et al., C.A. No. 2021-0681, or the Delaware Action. The plaintiffs in the Delaware Action asserted claims against (i) former members of Akcea’s board of directors; and (ii) Ionis, or collectively, the Defendants. The plaintiffs asserted putatively direct claims on behalf of a purported class of former Akcea stockholders. The plaintiffs in the Delaware Action asserted that the Defendants breached their fiduciary duties in connection with the October 2020 take-private transaction that Ionis and Akcea entered into, in which Akcea became a wholly-owned subsidiary of Ionis. We believe this lawsuit is without merit. However, the outcome of this lawsuit or any other lawsuit that may be filed challenging the October 2020 take-private transaction is uncertain. Accordingly, on June 3, 2022, the parties reached an agreement in principle to settle the Delaware Action for $ million. A Stipulation and Agreement of Compromise, Settlement and Release, or the Stipulation and Settlement Agreement reflecting the terms of the proposed settlement was executed and filed with the Delaware Court of Chancery on July 5, 2022. On October 11, 2022, the Delaware Court of Chancery entered an Order and Final Judgment, or the Order, approving the Stipulation and Settlement Agreement in full after determining that the Stipulation and Settlement Agreement was fair, reasonable, and adequate. The Order provides for the full settlement, satisfaction, compromise and release of all claims that were asserted in the Delaware Action. The Order contains no admission of wrongdoing on the part of any of the Defendants. We recorded a net settlement expense of $ million within other expense in the accompanying consolidated statements of operations in 2022. On , 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. . , or the Shumacher Action. The complaint names Ionis’ 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’ fees and costs, and such other relief as deemed just and proper by the court. On , 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. On , 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. . , 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 , and . On , the Cohen Action Plaintiff filed a motion to consolidate the related Cohen Action and Shumacher Action. On , the Court denied the motion to consolidate in favor of the settlement pending in the Shumacher Action. On , Ionis filed a Form -K disclosing the pending settlement and attaching the Notice of Pendency of Settlement of Action. On , 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. We and our Board have denied, and continue to deny, any and all allegations of wrongdoing or liability asserted in the Shumacher and Cohen Actions. |

Basis of Presentation | Basis of Presentation In our consolidated financial statements we included the accounts of Ionis Pharmaceuticals, Inc. and the consolidated results of our subsidiary, Akcea Therapeutics, Inc. and its wholly owned subsidiaries (“we”, “us” or “our”). We formed Akcea in December 2014. In July 2017, Akcea completed an initial public offering, or IPO, which reduced our ownership of Akcea’s common stock below 100 percent. In October 2020, we completed a merger transaction with Akcea such that following the completion of the merger, Akcea became our wholly owned subsidiary. We will refer to this transaction as the Akcea Merger throughout the remainder of this document. We reflected changes in our ownership percentage in our financial statements as an adjustment to noncontrolling interest in the period the changes occurred . |
Use of Estimates | Use of Estimates We prepare our consolidated financial statements in conformity with accounting principles generally accepted in the U.S. that require us to make estimates and assumptions that affect the amounts reported in our consolidated financial statements and accompanying notes. Actual results could differ from our estimates. |
Revenue Recognition | Revenue Recognition We generally recognize revenue when we have satisfied all contractual obligations and are reasonably assured of collecting the resulting receivable. We are often entitled to bill our customers and receive payment from our customers in advance of recognizing the revenue. In the instances in which we have received payment from our customers in advance of recognizing revenue, we include the amounts within deferred revenue in our consolidated balance sheets. At contract inception, we analyze our collaboration arrangements to assess whether such arrangements involve joint operating activities performed by parties that are both active participants in the activities and exposed to significant risks and rewards dependent on the commercial success of such activities and therefore within the scope of ASC Topic 808, Collaborative Arrangements ASC does not address the recognition and measurement of collaborative arrangements and instead refers companies to use other authoritative accounting literature. For collaboration arrangements within the scope of ASC that contain multiple elements, we determine which elements of the collaboration reflect a vendor-customer relationship and therefore are within the scope of ASC , Revenue from Contracts with Customers . When we determine elements of a collaboration do not reflect a vendor-customer relationship, we consistently apply the reasonable and rational policy election we made by analogizing to authoritative accounting literature We evaluate the income statement classification for presentation of amounts due from or owed to other participants associated with multiple activities in a collaboration arrangement based on the nature of each separate activity. For example, in our eplontersen collaboration with AstraZeneca, we recognize funding received from AstraZeneca for co-development activities as revenue; while we recognize cost sharing payments to and from AstraZeneca associated with co-commercialization activities and co-medical affairs activities as SG&A expense and research and development expense, respectively. Steps to Recognize Revenue For elements of our contractual relationships that we account for under ASC 606, we use a five-step process to determine the amount of revenue we should recognize and when we should recognize it. The five-step process is as follows: 1. Identify the contract Accounting rules require us to first determine if we have a contract with our partner, including confirming that we have met each of the following criteria: ● We and our partner approved the contract and we are both committed to perform our obligations; ● We have identified our rights, our partner’s rights and the payment terms; ● We have concluded that the contract has commercial substance, meaning that the risk, timing, or amount of our future cash flows is expected to change as a result of the contract; and ● We believe collectability of the consideration is probable. 2. Identify the performance obligations We next identify our performance obligations, which represent the distinct goods and services we are required to provide under the contract. We frequently enter into a collaboration agreement in which we provide our partner with an option to license a medicine in the future. We may also provide our partner with an option to request that we provide additional goods or services in the future, such as active pharmaceutical ingredient, or API. We evaluate whether these options are material rights at the inception of the agreement. If we determine an option is a material right, we will consider the option a separate performance obligation. Historically, we have concluded that the options we grant to license a medicine in the future or to provide additional goods and services as requested by our partner are not material rights because these items are contingent upon future events that may not occur and are not priced at a significant discount. When a partner exercises its option to license a medicine or requests additional goods or services, then we identify a new performance obligation for that item In some cases, we deliver a license at the start of an agreement. If we determine that our partner has full use of the license and we do not have any additional material performance obligations related to the license after delivery, then we consider the license to be a separate performance obligation. Refer to the section titled, Eplontersen Collaboration with AstraZeneca 3. Determine the transaction price We then determine the transaction price by reviewing the amount of consideration we are eligible to earn under the collaboration agreement, including any variable consideration. Under our collaboration agreements, consideration typically includes fixed consideration in the form of an upfront payment and variable consideration in the form of potential milestone payments, license fees and royalties. At the start of an agreement, our transaction price usually consists of only the upfront payment. We do not typically include any payments we may receive in the future in our initial transaction price because the payments are not probable and are contingent on certain future events. We reassess the total transaction price at each reporting period to determine if we should include additional payments in the transaction price. Milestone payments are our most common type of variable consideration. We recognize milestone payments using the most likely amount method because we will either receive the milestone payment or we will not, which makes the potential milestone payment a binary event. The most likely amount method requires us to determine the likelihood of earning the milestone payment. We include a milestone payment in the transaction price once it is probable we will achieve the milestone event. Most often, we do not consider our milestone payments probable until we or our partner achieve the milestone event because the majority of our milestone payments are contingent upon events that are not within our control and/ or are usually based on scientific progress which is inherently uncertain. 4. Allocate the transaction price Next, we allocate the transaction price to each of our performance obligations. When we have to allocate the transaction price to more than performance obligation, we make estimates of the relative stand-alone selling price of each performance obligation because we do not typically sell our goods or services on a stand-alone basis. We then allocate the transaction price to each performance obligation based on the relative stand-alone selling price. We do not reallocate the transaction price after the start of an agreement to reflect subsequent changes in stand-alone selling prices. We may engage a party, independent valuation specialist to assist us with determining a stand-alone selling price for collaborations in which we deliver a license at the start of an agreement. We estimate the stand-alone selling price of these licenses using valuation methodologies, such as the relief from royalty method. Under this method, we estimate the amount of income, net of taxes, for the license. We then discount the projected income to present value. The significant inputs we use to determine the projected income of a license could include ● Estimated future product sales; ● Estimated royalties we may receive from future product sales; ● Estimated contractual milestone payments we may receive; ● Estimated expenses we may incur; ● Estimated income taxes; and ● A discount rate. We typically estimate the selling price of research and development, or R&D, services by using our internal estimates of the cost to perform the specific services. The significant inputs we use to determine the selling price of our R&D services include: ● The estimated number of internal hours we will spend performing these services; ● The estimated cost of work we will perform; ● The estimated cost of work that we will contract with third parties to perform; and ● The estimated cost of API we will use. For purposes of determining the stand-alone selling price of the R&D services we perform and the API we will deliver, accounting guidance requires us to include a markup for a reasonable profit margin. 5. Recognize revenue We recognize revenue in of ways, over time or at a point in time. We recognize revenue over time when we are executing on our performance obligation over time and our partner receives benefit over time. For example, we recognize revenue over time when we provide R&D services. We recognize revenue at a point in time when our partner receives full use of an item at a specific point in time. For example, we recognize revenue at a point in time when we deliver a license or API to a partner. For R&D services that we recognize over time, we measure our progress using an input method. The input methods we use are based on the effort we expend or costs we incur toward the satisfaction of our performance obligation. We estimate the amount of effort we expend, including the time we estimate it will take us to complete the activities, or costs we incur in a given period, relative to the estimated total effort or costs to satisfy the performance obligation. This results in a percentage that we multiply by the transaction price to determine the amount of revenue we recognize each period. This approach requires us to make numerous estimates and use significant judgement. If our estimates or judgements change over the course of the collaboration, they may affect the timing and amount of revenue that we recognize in the current and future periods. Amendments to Agreements From time to time we amend our collaboration agreements. When this occurs, we are required to assess the following items to determine the accounting for the amendment: 1) If the additional goods and/or services are distinct from the other performance obligations in the original agreement; and 2) If the goods and/or services are sold at a stand-alone selling price. If we conclude the goods and/or services in the amendment are distinct from the performance obligations in the original agreement and at a stand-alone selling price, we account for the amendment as a separate agreement. If we conclude the goods and/or services are not distinct and are sold at a stand-alone selling price, we then assess whether the remaining goods or services are distinct from those already provided. If the goods and/or services are distinct from what we have already provided, then we allocate the remaining transaction price from the original agreement and the additional transaction price from the amendment to the remaining goods and/or services. If the goods and/or services are not distinct from what we have already provided, we update the transaction price for our single performance obligation and recognize any change in our estimated revenue as a cumulative-effect adjustment. Multiple agreements From time to time, we may enter into separate agreements at or near the same time with the same partner. We evaluate such agreements to determine whether we should account for them individually as distinct arrangements or whether the separate agreements should be combined and accounted for together. We evaluate the following to determine the accounting for the agreements: ● Whether the agreements were negotiated together with a single objective; ● Whether the amount of consideration in one contract depends on the price or performance of the other agreement; or ● Whether the goods and/or services promised under the agreements are a single performance obligation. Our evaluation involves significant judgment to determine whether a group of agreements might be so closely related that accounting guidance requires us to account for them as a combined arrangement. Refer to Part IV, Item 15, Note 7, Collaborative Arrangements and Licensing Agreements Our Revenue Sources The following are sources of revenue and when we typically recognize revenue. Commercial Revenue: SPINRAZA royalties and Licensing and other royalty revenue We earn commercial revenue primarily in the form of royalty payments on net sales of SPINRAZA. We recognize royalty revenue, including royalties from SPINRAZA sales, in the period in which the counterparty sells the related product and recognizes the related revenue, which in certain cases may require us to estimate our royalty revenue Commercial Revenue: TEGSEDI and WAYLIVRA revenue, net In January 2021 and April 2021, we entered into distribution agreements with Swedish Orphan Biovitrum AB, or Sobi, in which Sobi began commercializing TEGSEDI and WAYLIVRA in Europe and TEGSEDI in North America, respectively. Under our agreements, we are responsible for supplying finished goods inventory to Sobi and Sobi is responsible for selling each medicine to the end customer. As a result of these agreements, we earn a distribution fee on net sales from Sobi for each medicine. Under our collaboration agreement with PTC Therapeutics International Limited, or PTC, PTC is responsible for commercializing TEGSEDI and WAYLIVRA in Latin America and Caribbean countries. Under our agreement, we started receiving royalties from PTC for TEGSEDI sales in December 2021. Prior to the second quarter of 2021 in North America, we sold TEGSEDI through exclusive distribution agreements with third-party logistics companies, or 3PLs, that took title to TEGSEDI. The 3PLs then distributed TEGSEDI to a specialty pharmacy and a specialty distributor, which we collectively refer to as wholesalers, who then distributed TEGSEDI to health care providers and patients. In the United States, or U.S., we had a single 3PL as our sole customer and in Canada we also had a single 3PL as our sole customer. Prior to 2021 in Europe, we sold TEGSEDI and WAYLIVRA to hospitals and pharmacies, which were our customers, using 3PLs as distributors. Under our distribution agreements with Sobi we concluded that our performance obligation is to provide services to Sobi over the term of the agreement, which includes supplying finished goods inventory to Sobi. We are also responsible for maintaining the marketing authorization for TEGSEDI and WAYLIVRA in major markets and for leading the global commercial strategy for each medicine. We view this performance obligation as a series of distinct activities that are substantially the same. Therefore, we recognize as revenue the price Sobi pays us for the inventory when we deliver the finished goods inventory to Sobi. We also recognize distribution fee revenue based on Sobi’s net sales of TEGSEDI and WAYLIVRA. Under our agreements with Sobi, Sobi does not generally have a right of return. Prior to our distribution agreements with Sobi, we recognized TEGSEDI and WAYLIVRA commercial revenue in the period when our customer obtained control of our products, which occurred at a point in time upon transfer of title to the customer. We classified payments to customers or other parties in the distribution channel for services that were distinct and priced at fair value as selling, general and administrative, or SG&A, expenses in our consolidated statements of operations. We classified payments to customers or other parties in the distribution channel that did not meet those criteria as a reduction of revenue, as discussed further below. We excluded from revenues taxes collected from customers relating to TEGSEDI and WAYLIVRA commercial revenue and remitted these amounts to governmental authorities. Research and development revenue under collaboration agreements We enter into collaboration agreements to license and sell our technology on an exclusive or non-exclusive basis. Our collaboration agreements typically contain multiple elements, or performance obligations, including technology licenses or options to obtain technology licenses, R&D services and manufacturing services. We provide details about our collaboration agreements in Note 7, Collaborative Arrangements and Licensing Agreements Upfront payments: When we enter into a collaboration agreement and receive an upfront payment, we typically record the entire upfront payment as deferred revenue if our only performance obligation is for R&D services we will provide in the future. We amortize the upfront payment into revenue as we perform the R&D services. Milestone payments: We include additional consideration in the transaction price when it is probable. We typically include milestone payments for R&D services in the transaction price when they are achieved. We include these milestone payments when they are achieved because typically there is considerable uncertainty in the research and development processes that trigger these payments. Similarly, we include approval milestone payments in the transaction price once the medicine is approved by the applicable regulatory agency. We will recognize sales-based milestone payments in the period in which we achieve the milestone under the sales-based royalty exception allowed under accounting rules. We recognize milestone payments that relate to an ongoing performance obligation over our period of performance. For example, when we achieve a milestone payment from a partner for advancing a clinical study under a collaboration agreement, we add the milestone payment to the transaction price if the milestone relates to an ongoing R&D services performance obligation and recognize revenue related to the milestone payment over our estimated period of performance. If we have partially completed our performance obligation, then we record a cumulative-effect adjustment in the period we add the milestone to the transaction price. Conversely, we recognize in full those milestone payments that we earn based on our partners’ activities when our partner achieves the milestone event and we do not have a performance obligation. License fees: We generally recognize as revenue the total amount we determine to be the relative stand-alone selling price of a license when we deliver the license to our partner. This is because our partner has full use of the license and we do not have any additional performance obligations related to the license after delivery. Sublicense fees: We recognize sublicense fee revenue in the period in which a party, who has already licensed our technology, further licenses the technology to another party because we do not have any performance obligations related to the sublicense. Eplontersen Collaboration with AstraZeneca In December 2021, we entered into a joint development and commercialization agreement with AstraZeneca to develop and commercialize eplontersen for the treatment of transthyretin amyloidosis, or ATTR. We are jointly developing and preparing to commercialize eplontersen with AstraZeneca in the U.S. We granted AstraZeneca exclusive rights to commercialize eplontersen outside the U.S., except certain countries in Latin America. Under the terms of the agreement, we received a $200 million upfront payment in 2021. We evaluated our eplontersen collaboration under ASC 808 and identified four material components: (i) the license we granted to AstraZeneca in 2021, (ii) the co-development activities that we and AstraZeneca are performing, (iii) the co-commercialization activities that we and AstraZeneca are performing and (iv) the co-medical affairs activities that we and AstraZeneca are performing. We determined that we had a vendor-customer relationship within the scope of ASC 606 for the license we granted to AstraZeneca and as a result we had one performance obligation. For our sole performance obligation, we determined the transaction price was the $200 million upfront payment we received. We recognized the upfront payment in full in 2021 because we did not have any remaining performance obligations after we delivered the license to AstraZeneca. We also concluded that the co-development activities, the co-commercialization activities and the co-medical affairs activities are within the scope of ASC 808 because we and AstraZeneca are active participants exposed to the risks and benefits of the activities under the collaboration and therefore do not have a vendor-customer relationship. AstraZeneca is currently responsible for 55 percent of the costs associated with the ongoing global Phase 3 development program. Because we are leading the Phase 3 development program, we made an accounting policy election to recognize as non-customer revenue the cost-share funding from AstraZeneca, net of our share of AstraZeneca’s development expenses, in the same period we incur the related development expenses. As AstraZeneca is responsible for the majority of the commercial and medical affairs costs in the U.S. and all costs associated with bringing eplontersen to market outside the U.S., we made an accounting policy election to recognize cost-share funding we receive from AstraZeneca related to commercial and medical affairs activities as reductions of our SG&A expense and R&D expense, respectively. |
Contracts Receivable | Contracts Receivable Our contracts receivable balance represents the amounts we have billed our partners or customers and that are due to us unconditionally for goods we have delivered or services we have performed. When we bill our partners or customers with payment terms based on the passage of time, we consider the contracts receivable to be unconditional. We typically receive payment within one quarter of billing our partner or customer As of December 31, 2022, approximately 82.5 percent of our contracts receivables were from one significant customer. As of December 31, 2021, approximately 93.8 percent of our contracts receivables were from two significant customers. |
Unbilled SPINRAZA Royalties | Unbilled SPINRAZA Royalties Our unbilled SPINRAZA royalties represent our right to receive consideration from Biogen in advance of when we are eligible to bill Biogen for SPINRAZA royalties. We include these unbilled amounts in other current assets in our consolidated balance sheets. |
Deferred Revenue | Deferred Revenue We are often entitled to bill our customers and receive payment from our customers in advance of our obligation to provide services or transfer goods to our partners. In these instances, we include the amounts in deferred revenue in our consolidated balance sheets. |
Cost of Sales | Cost of Sales Our cost of sales is comprised of costs related to our commercial revenue, including manufacturing costs, transportation and freight costs and indirect overhead costs associated with the manufacturing and distribution of our products. We also may include certain period costs related to manufacturing services and inventory adjustments in cost of sales. |
Research, Development and Patent Expenses | Research, Development and Patent Expenses Our research, development and patent expenses include wages, benefits, facilities, supplies, external services, clinical trial and manufacturing costs, patents and other expenses that are directly related to our research and development operations. We expense research and development costs as we incur them. When we make payments for research and development services prior to the services being rendered, we record those amounts as prepaid assets in our consolidated balance sheets and we expense them as the services are provided. A portion of the costs included in research and development expenses are costs associated with our partner agreements. In 2022, 2021 and 2020, patent expenses were $4.7 million, $5.3 million and $4.1 million, respectively. |
Income Taxes | Income Taxes We account for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in our financial statements or tax returns. In addition, deferred tax assets are recorded for the future benefit of utilizing net operating losses and research and development credit carryforwards. We record a valuation allowance when necessary to reduce our net deferred tax assets to the amount expected to be realized. We apply the authoritative accounting guidance prescribing a threshold and measurement attribute for the financial recognition and measurement of a tax position taken or expected to be taken in a tax return. We recognize liabilities for uncertain tax positions based on a two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step requires us to estimate and measure the tax benefit as the largest amount that is more than 50 percent likely to be realized upon ultimate settlement. We are required to use significant judgment in evaluating our uncertain tax positions and determining our provision for income taxes. Although we believe our reserves are reasonable, we can provide no assurance that the final tax outcome of these matters will not be different from that which we have reflected in our historical income tax provisions and accruals. We adjust these reserves for changing facts and circumstances, such as the closing of a tax audit or the refinement of an estimate. To the extent that the final tax outcome of these matters is different than the amounts recorded, such differences may impact the provision for income taxes in the period in which we make such determination. We are also required to use significant judgment in determining any valuation allowance recorded against our deferred tax assets. In assessing the need for a valuation allowance, we consider all available evidence, including scheduled reversal of deferred tax liabilities, past operating results, the feasibility of tax planning strategies and estimates of future taxable income. We base our estimates of future taxable income on assumptions that are consistent with our plans. The assumptions we use represent our best estimates and involve inherent uncertainties and the application of our judgment. Should actual amounts differ from our estimates, the amount of our tax expense and liabilities we recognize could be materially impacted. We record a valuation allowance to reduce the balance of our net deferred tax assets to the amount we believe is more-likely-than-not to be realized. We do not provide for a U.S. income tax liability and foreign withholding taxes on undistributed foreign earnings of our foreign subsidiaries. |
Basic and Diluted Net Loss per Share | Basic and Diluted Net Loss per Share Basic net loss per share We compute basic net loss per share by dividing the total net loss attributable to our common stockholders by our weighted-average number of common shares outstanding during the period. For the years ended December 31, 2022 and 2021, we did not have to consider Akcea results separately in our calculation because we owned 100 percent of Akcea for the entire period. Our basic net loss per share for the years ended December 31, 2022 and 2021 was $1.90 and $0.20, respectively. For the year ended December 31, 2020, we calculated total net loss attributable to our common stockholders using our net loss for Ionis on a stand-alone basis plus our share of Akcea’s net loss for the period. To calculate the portion of Akcea’s net loss attributable to our ownership, we multiplied Akcea’s net loss per share by the weighted average shares we owned in Akcea. As a result of this calculation, our total net loss available to Ionis common stockholders for the calculation of net loss per share was different than net loss attributable to Ionis Pharmaceuticals, Inc. common stockholders in our consolidated statements of operations. We calculated our basic net loss per share for the year ended December 31, 2020 as follows (in thousands, except per share amounts): Year Ended December 31, 2020 Weighted Average Shares Owned in Akcea Akcea s Net Loss Per Share Basic Net Loss Per Share Calculation Akcea’s net loss in the pre-merger period attributable to our ownership 77,095 $ (1.45 ) $ (111,775 ) Akcea’s net loss in the post-merger period attributable to our ownership (85,987 ) Akcea’s total net loss attributable to our ownership $ (197,762 ) Ionis’ stand-alone net loss (246,702 ) Net loss available to Ionis common stockholders $ (444,464 ) Weighted average shares outstanding 139,612 Basic net loss per share $ (3.18 ) Diluted net loss per share For the years ended December 31, 2022, 2021 and 2020, we incurred a net loss; therefore, we did not include dilutive common equivalent shares in the computation of diluted net loss per share because the effect would have been anti-dilutive. Common stock underlying the following would have had an anti-dilutive effect on net loss per share: ● 0.125 percent convertible senior notes, or Notes; ● Note hedges related to the Notes; ● 1 percent convertible senior notes, or Notes; ● Dilutive stock options; ● Unvested restricted stock units, or RSUs; ● Unvested performance restricted stock units, or PRSUs; and ● Employee Stock Purchase Plan, or ESPP. For the years ended December 31, 2022 and 2021, common stock underlying the following would also have had an anti-dilutive effect on net loss per share: ● 0 percent convertible senior notes, or Notes; and ● Note hedges related to the Notes. Additionally as of December 31, 2022 and 2021, we had warrants related to our 0 percent and 0.125 percent Notes outstanding. We will include the shares issuable under these warrants in our calculation of diluted earnings per share when the average market price per share of our common stock for the reporting period exceeds the strike price of the warrants. |
Stock-Based Compensation Expense | Stock-Based Compensation Expense 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 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 recognize compensation expense for stock options granted, 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. Stock Options and Stock Purchase Rights: We use the Black-Scholes model to estimate the fair value of stock options granted and stock purchase rights under our ESPP. 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. The expected term of stock options granted represents the period of time that we expect them to be outstanding. Historically, we estimated the expected term of options granted based on historical exercise patterns. In 2021, our Compensation Committee approved an amendment to the 2011 Equity Incentive Plan, or 2011 Plan, and the 2020 Equity Incentive Plan, or 2020 Plan, that increased the contractual term of stock options granted under these plans from seven years to ten years for stock options granted on January 1, 2022 and thereafter. We determined that we are unable to rely on our historical exercise data as a basis for estimating the expected life of stock options granted to employees following this change because the contractual term changed and we have no other means to reasonably estimate future exercise behavior. We therefore used the simplified method for determining the expected life of stock options granted to employees in the year ended December 31, 2022. Under the simplified method, we calculate the expected term as the average of the time-to-vesting and the contractual life of the options. As we gain additional historical information, we will transition to calculating our expected term based on our historical exercise patterns. RSU’s: 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 employees vest annually over a four-year period. The RSUs we granted to our board of directors prior to June 2020 vest annually over a four-year period. RSUs granted to our board of directors after June 2020 fully vest after one year. PRSU’s: Beginning in 2020, we added PRSU awards to the compensation for our Chief Executive Officer, Dr. Brett Monia. Beginning in 2022, we added PRSU awards to the compensation for our other Section 16 officers. Under the terms of the grants, one third 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. We are recognizing the grant date fair value of these awards as stock-based compensation expense using the accelerated multiple-option approach over the vesting period.

Noncontrolling Interest in Akcea Therapeutics, Inc. | Noncontrolling Interest in Akcea Therapeutics, Inc. Since Akcea’s IPO in July 2017 and prior to the Akcea Merger in October 2020, the shares of Akcea’s common stock third parties owned represented an interest in Akcea’s equity that we did not control. During this period our ownership ranged from to . However, as we maintained overall control of Akcea through our voting interest, we reflected the assets, liabilities and results of operations of Akcea in our consolidated financial statements. Since Akcea’s IPO in July 2017 and through the closing of the Akcea Merger, we reflected the noncontrolling interest attributable to other owners of Akcea’s common stock on a separate line in our statements of operations and a separate line within stockholders’ equity in our consolidated balance sheets. In addition, through the closing of the Akcea Merger, we recorded a noncontrolling interest adjustment to account for the stock options Akcea granted, which if exercised, would have diluted our ownership in Akcea. This adjustment was a reclassification within stockholders’ equity from additional paid-in capital to noncontrolling interest in Akcea equal to the amount of stock-based compensation expense Akcea had recognized. Additionally, w |
Accumulated Other Comprehensive Loss | Accumulated Other Comprehensive Loss Accumulated other comprehensive loss is comprised of unrealized gains and losses on investments, net of taxes and currency translation adjustments. The following table summarizes changes in accumulated other comprehensive loss for the years ended December 31, 2022, 2021 and 2020 (in thousands): Year Ended December 31, 2022 2021 2020 Beginning balance accumulated other comprehensive loss $ (32,668 ) $ (21,071 ) $ (25,290 ) Unrealized gains (losses) on securities, net of tax (1) (24,395 ) (11,486 ) 3,729 Currency translation adjustment (417 ) (111 ) 617 Adjustments to other comprehensive loss from purchase of noncontrolling interest of Akcea Therapeutics, Inc. — — (127 ) Net other comprehensive income (losses) for the year (24,812 ) (11,597 ) 4,219 Ending balance accumulated other comprehensive loss $ (57,480 ) $ (32,668 ) $ (21,071 ) ________________ (1) We did not have tax expense included in our other comprehensive loss for the years ended December 31, 2022, 2021 and 2020. |
Concentration of Credit Risk | Concentration of Credit Risk Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash equivalents, short-term investments and receivables. We place our cash equivalents and short-term investments with reputable financial institutions. We primarily invest our excess cash in commercial paper and debt instruments of the U.S. Treasury, financial institutions, corporations, and U.S. government agencies with strong credit ratings and an investment grade rating at or above A-1, P-1 or F-1 by Moody’s, Standard & Poor’s, or S&P, or Fitch, respectively. We have established guidelines relative to diversification and maturities that maintain safety and liquidity. We periodically review and modify these guidelines to maximize trends in yields and interest rates without compromising safety and liquidity. |
Fair Value Measurements | Fair Value Measurements We have estimated the fair value of our financial instruments. The amounts reported for cash, accounts receivable, accounts payable and accrued expenses approximate the fair value because of their short maturities. We report our investment securities at their estimated fair value based on quoted market prices for identical or similar instruments. |
Cash, Cash Equivalents and Investments | Cash, Cash Equivalents and Investments We consider all liquid investments with maturities of three months or less when we purchase them to be cash equivalents. Our short-term investments have initial maturities of greater than three months from date of purchase. We classify our short-term debt investments as “available-for-sale” and carry them at fair market value based upon prices on the last day of the fiscal period for identical or similar items. We record unrealized gains and losses on debt securities as a separate component of comprehensive income (loss) and include net realized gains and losses in gain (loss) on investments in our consolidated statements of operations. We use the specific identification method to determine the cost of securities sold. We also have equity investments of less than 20 percent ownership in publicly and privately held biotechnology companies that we received as part of a technology license or partner agreement. At December 31, 2022, we held equity investments in three publicly traded companies and eight privately held companies. We are required to measure and record our equity investments at fair value and to recognize the changes in fair value in our consolidated statements of operations. We account for our equity investments in privately held companies at their cost minus impairments, plus or minus changes resulting from observable price changes in orderly transactions for the identical or similar investment of the same issuer. |
Inventories | Inventories We reflect our inventory in our consolidated balance sheets at the lower of cost or net realizable value under the first-in, first-out method, or FIFO. We capitalize the costs of raw materials that we purchase for use in producing our medicines because until we use these raw materials, they have alternative future uses, which we refer to as clinical raw materials. We include in inventory raw material costs for medicines that we manufacture for our partners under contractual terms and that we use primarily in our clinical development activities and drug products. We can use each of our raw materials in multiple products and, as a result, each raw material has future economic value independent of the development status of any single medicine. For example, if one of our medicines failed, we could use the raw materials for that medicine to manufacture our other medicines. We expense these costs as R&D expenses when we begin to manufacture API for a particular medicine if the medicine has not been approved for marketing by a regulatory agency. Our raw materials- commercial inventory includes API for our commercial medicines. We capitalize material, labor and overhead costs as part of our raw materials- commercial inventory. We review our inventory periodically and reduce the carrying value of items we consider to be slow moving or obsolete to their estimated net realizable value based on forecasted demand compared to quantities on hand. We consider several factors in estimating the net realizable value, including shelf life of our inventory, alternative uses for our medicines in development and historical write-offs. Our inventory consisted of the following (in thousands): December 31, 2022 2021 Raw materials: Raw materials- clinical $ 17,061 $ 14,507 Raw materials- commercial 2,699 4,139 Total raw materials 19,760 18,646 Work in process 2,109 5,770 Finished goods 164 390 Total inventory $ 22,033 $ 24,806 |
Property, Plant and Equipment | Property, Plant and Equipment We carry our property, plant and equipment at cost and depreciate it on the straight-line method over its estimated useful life, which consists of the following (in thousands): Estimated Useful December 31, Lives (in years) 2022 2021 Computer software, laboratory, manufacturing and other equipment 3 to 10 $ 74,351 $ 72,802 Building, building improvements and building systems 15 to 40 41,158 144,046 Land improvements 20 - 10,077 Leasehold improvements 5 to 15 28,357 20,144 Furniture and fixtures 5 to 10 9,575 10,591 153,441 257,660 Less accumulated depreciation (87,716 ) (102,653 ) 65,725 155,007 Land 8,569 23,062 Total $ 74,294 $ 178,069 In October 2022, we sold the facilities and related land at our headquarters for net proceeds of $202.6 million in connection with a sale and leaseback transaction. In connection with the sale of these real estate assets, we de-recognized the related land and improvements, building and building improvements, which resulted in a net gain of $150.1 million that we reported in other income (expense) in our consolidated statements of operations. We depreciate our leasehold improvements using the shorter of the estimated useful life or remaining lease term. We evaluate long-lived assets, which include property, plant and equipment, for impairment on at least a quarterly basis and whenever events or changes in circumstances indicate that we may not be able to recover the carrying amount of such assets. |
Estimated Liability for Clinical Development Costs | Estimated Liability for Clinical Development Costs We have numerous medicines in preclinical studies and/or clinical trials at clinical sites throughout the world. On at least a quarterly basis, we estimate our liability for preclinical and clinical development costs we have incurred and services that we have received but for which we have not yet been billed and maintain an accrual to cover these costs. These costs primarily relate to third-party clinical management costs, laboratory and analysis costs, toxicology studies and investigator grants. We estimate our liability using assumptions about study and patient activities and the related expected expenses for those activities determined based on the contracted fees with our service providers. The assumptions we use represent our best estimates of the activity and expenses at the time of our accrual and involve inherent uncertainties and the application of our judgment. Upon settlement, these costs may differ materially from the amounts accrued in our consolidated financial statements. Our historical accrual estimates have not been materially different from our actual amounts. |
Convertible Debt | Convertible Debt We account for each of our convertible debt instruments as a single unit of accounting, a liability, because we concluded that the conversion features do not require bifurcation as a derivative under ASC 815-15 and we did not issue our convertible debt instruments at a substantial premium. We record debt issuance costs as contra-liabilities in our consolidated balance sheets at issuance and amortize them over the contractual term of the convertible debt instrument using the effective interest rate. balances of our convertible senior notes presented in our consolidated balance sheets represent the principal balance of each convertible debt instrument less debt issuance costs. As of December 31, 2022, we had two outstanding convertible senior notes, our 0% Notes, which mature in April 2026, and our 0.125% Notes, which mature in December 2024. Refer to Part IV, Item 15, Note 4, Long-Term Obligations and Commitments |
Call Spread | Call Spread In conjunction with the issuance of our 0% Notes and 0.125% Notes in April 2021 and December 2019, respectively, we entered into call spread transactions, which were comprised of purchasing note hedges and selling warrants. We account for the note hedges and warrants as separate freestanding financial instruments and treat each instrument as a separate unit of accounting. We determined that the note hedges and warrants do not meet the definition of a liability using the guidance contained in ASC Topic 480; therefore, we account for the note hedges and warrants using the Derivatives and Hedging – Contracts in Entity’s Own Equity |
Leases | Leases We determine if an arrangement contains a lease at inception. We currently only have operating leases. We recognize a right-of-use operating lease asset and associated short- and long-term operating lease liability in our consolidated balance sheets for operating leases greater than one year. Our right-of-use assets represent our right to use an underlying asset for the lease term and our lease liabilities represent our obligation to make lease payments arising from the lease arrangement. We recognize our right-of-use operating lease assets and lease liabilities based on the present value of the future minimum lease payments we will pay over the lease term. As our leases do not provide an interest rate implicit in the lease, we use our incremental borrowing rate, based on the information available as of the lease inception date or at the lease option extension date in determining the present value of future payments. We recognize rent expense for our minimum lease payments on a straight-line basis over the expected term of our lease. Our leases do not include material variable or contingent lease payments. We recognize period expenses, such as common area maintenance expenses, in the period we incur the expense. |
Segment Information | Segment Information In 2021, we began operating as a single segment, Ionis operations, because our chief decision maker reviews operating results on an aggregate basis and manages our operations as a single . |
Recently Adopted Accounting Standards | Recently Adopted Accounting Standards In June 2022, the Financial Accounting Standards Board, or FASB, issued clarifying guidance on fair value measurement of equity securities subject to contractual trading restrictions. The guidance clarifies that contractual trading restrictions are not considered part of the unit of account of equity securities and therefore, are not considered when measuring the fair value of equity securities. This update is effective for interim and annual periods beginning January 1, 2024 on a prospective basis. Early adoption of this guidance is permitted at an interim or annual period. We early adopted this new guidance in the third quarter of 2022. This guidance did not have a material impact on our consolidated financial statements. We do not expect any other recently issued accounting standards to have a material impact to our financial results. |

Temporarily Impaired Investments | The following is a summary of our investments we considered to be temporarily impaired at (in thousands). All of these investments have less than 12 months of temporary impairment. 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. We believe it is more likely than not that we will be able to hold our debt securities to maturity. Therefore, we anticipate full recovery of our debt securities’ amortized cost basis at maturity.
