IONIS PHARMACEUTICALS, INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
September 30, 2019
(Unaudited)

1.  Basis of Presentation


We prepared the unaudited interim condensed consolidated financial statements for the three and nine months ended September 30, 2019 and 2018 on the same basis as the audited financial statements for the year ended December 31, 2018. We included all normal recurring adjustments in the financial statements, which we considered necessary for a fair presentation of our financial position at such dates and our operating results and cash flows for those periods. Results for the interim periods are not necessarily indicative of the results for the entire year. For more complete financial information, these financial statements, and notes thereto, should be read in conjunction with the audited financial statements for the year ended December 31, 2018 included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission, or SEC.


In the condensed consolidated financial statements, we included the accounts of Ionis Pharmaceuticals, Inc. and the consolidated results of our majority owned affiliate, Akcea Therapeutics, Inc. and its wholly owned subsidiaries. We formed Akcea in December 2014. In July 2017, Akcea completed an initial public offering, or IPO, and therefore, beginning in July 2017, we no longer owned 100 percent of Akcea. In the first quarter of 2019, we received 2.8 million shares of Akcea common stock as payment for the sublicense fee Akcea owed us when Novartis licensed AKCEA-APO(a)-LRx.. At September 30, 2019, our ownership was approximately 75 percent. In the fourth quarter of 2019, we expect to receive an additional 6.9 million shares of Akcea common stock as payment for the sublicense fee Akcea owes us for Pfizer’s license of AKCEA-ANGPTL3-LRx. We reflect changes in our ownership of Akcea in our financial statements in the period the change occurs. Refer to the section titled “Noncontrolling Interest in Akcea” in Note 2, Significant Accounting Policies, for further information related to our accounting for our investment in Akcea.


Unless the context requires otherwise, “Ionis”, “Company,” “we,” “our,” and “us” refers to Ionis Pharmaceuticals, Inc. and its majority owned affiliate, Akcea Therapeutics, Inc. and its wholly owned subsidiaries.

2.  Significant Accounting Policies


Revenue Recognition


Our Revenue Sources


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 in deferred revenue on our consolidated balance sheet.


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 will also recognize as commercial revenue future sales milestone payments and royalties we earn under our partnerships.



Commercial Revenue: Product sales, net



We added product sales from TEGSEDI to our commercial revenue in the fourth quarter of 2018 and we added product sales from WAYLIVRA to our commercial revenue in the third quarter of 2019. In the U.S., we distribute TEGSEDI through an exclusive distribution agreement with a third-party logistics company, or 3PL, that takes title to TEGSEDI. The 3PL is our sole customer in the U.S. The 3PL then distributes TEGSEDI to a specialty pharmacy and a specialty distributor, which we collectively refer to as wholesalers, who then distribute TEGSEDI to health care providers and patients. In Europe, prior to the third quarter of 2019 we distributed TEGSEDI through a non-exclusive distribution model with a 3PL that takes title to TEGSEDI. The 3PL was our sole customer in Europe. The 3PL in Europe then distributed TEGSEDI to hospitals and pharmacies. In the third quarter of 2019, we entered into a distribution arrangement with a 3PL and began to sell both TEGSEDI and WAYLIVRA directly to hospitals and pharmacies in Europe.



Research and development revenue under collaborative agreements


We often 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, research and development, or R&D, services, and manufacturing services.



We provide details about our collaboration agreements in Note 7, Collaborative Arrangements and Licensing Agreements, in our Annual Report on Form 10-K for the year ended December 31, 2018. Under each collaboration note we discuss our specific revenue recognition conclusions, including our significant performance obligations under each collaboration.

Steps to Recognize Revenue



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 is probable.


2.Identify the performance obligations



We next identify the distinct goods and services we are required to provide under the contract. Accounting rules refer to these as our performance obligations. We typically have only 1 performance obligation at the inception of a contract, which is to perform R&D services.



Often times we 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. These items are contingent upon future events that may not occur. 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.


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 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 are usually based on scientific progress. For example, in the first quarter of 2019, we earned $35 million in milestone payments from Roche when Roche dosed the first patient in the Phase 3 study of IONIS-HTTRx (RG6042). We did not consider these milestone payments probable until Roche achieved the milestone event because the dosing of a patient was a contingent event that was not within our control. We recognized the milestone payments in full in the period the milestone event was achieved because we did not have any remaining performance obligations related to the milestone payments.

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 one 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.


10



We may engage a third 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 on future product sales;
Contractual milestone payments;
Expenses we expect to incur;
Income taxes; and
A discount rate.


We typically estimate the selling price of 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 number of internal hours we estimate 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.


We do not reallocate the transaction price after the start of an agreement to reflect subsequent changes in stand-alone selling prices.

5.Recognize revenue



We recognize revenue in one of two 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. For example, in the third quarter of 2019, we updated our estimate of the total effort we expect to expend to satisfy our performance obligation under our 2013 Strategic Neurology collaboration with Biogen. As of September 30, 2019, we have completed a significant portion of the research and development services. We expect to complete the remainder of our services in 2020. As a result of our change in estimate, in the third quarter of 2019, we recorded a cumulative catch up adjustment of $16.5 million to decrease revenue. We expect to complete the remainder of our services in 2020. Refer to Note 7, Collaborative Arrangements and Licensing Agreements, for further discussion of the cumulative catch up adjustment we made.



The following are examples of when we typically recognize revenue based on the types of payments we receive.


Commercial Revenue: SPINRAZA royalties and Licensing and other royalty revenue



We recognize royalty revenue in the period in which the counterparty sells the related product, which in certain cases may require us to estimate our royalty revenue. We recognize royalties from SPINRAZA sales in the period in which Biogen records the sale of SPINRAZA.



Commercial Revenue: Product sales, net



We recognize product sales in the period when our customer obtains control of our products, which occurs at a point in time upon transfer of title to the customer. We classify payments to customers or other parties in the distribution channel for services that are distinct and priced at fair value as selling, general and administrative expenses in our condensed consolidated statements of operations. Otherwise, payments to customers or other parties in the distribution channel that do not meet those criteria are classified as a reduction of revenue, as discussed further below. We exclude from revenues taxes collected from customers relating to product sales and remitted to governmental authorities.


11



Reserves for Product sales


We record product sales at our net sales price, or transaction price. We include in our transaction price estimated reserves for discounts, returns, chargebacks, rebates, co-pay assistance and other allowances that we offer within contracts between us and our customers, wholesalers, health care providers and other indirect customers. We estimate our reserves using the amounts we have earned or what we can claim on the associated sales. We classify our reserves as a reduction of accounts receivable when we are not required to make a payment or as a current liability when we are required to make a payment. In certain cases, our estimates include a range of possible outcomes that are probability-weighted for relevant factors such as our historical experience, current contractual and statutory requirements, specific known market events and trends, industry data and forecasted customer buying and payment patterns. Overall, our reserves reflect our best estimates under the terms of our respective contracts. When calculating our reserves and related product sales, we only recognize amounts to the extent that we consider it probable that we would not have to reverse in a future period a significant amount of the cumulative sales we previously recognized. The actual amounts we receive may ultimately differ from our reserve estimates. If actual amounts in the future vary from our estimates, we will adjust these estimates, which would affect our net product sales in the respective period.



The following are the components of variable consideration related to product sales:

Chargebacks: In the U.S., we estimate obligations resulting from contractual commitments with the government and other entities to sell products to qualified healthcare providers at prices lower than the list prices charged to our U.S. customer. Our U.S. customer charges us for the difference between what it pays for the product and the selling price to the qualified healthcare providers. We also estimate the amount of chargebacks related to our estimated product remaining in the distribution channel at the end of the reporting period that we expect our customer to sell to healthcare providers in future periods. We record reserves for these chargebacks related to product sales to our U.S. customer during the reporting period.

Government rebates: We are subject to discount obligations under government programs, including Medicaid and Medicare programs in the U.S. and we record reserves for government rebates based on statutory discount rates and estimated utilization. We estimate Medicaid and Medicare rebates based on a range of possible outcomes that are probability-weighted for the estimated payer mix. We record these reserves as an accrued liability on our condensed consolidated balance sheet with a corresponding offset reducing our product sales in the same period we recognize the related sale. For Medicare, we also estimate the number of patients in the prescription drug coverage gap for whom we will owe an additional liability under the Medicare Part D program. On a quarterly basis, we update our estimates and record any adjustments in the period that we identify the adjustments.

Trade discounts: We provide customary invoice discounts on product sales to our U.S. customer for prompt payment. We record this discount as a reduction of product sales in the period in which we recognize the related product revenue.

Distribution services: We receive and pay for various distribution services from our U.S. and EU customers and wholesalers in the U.S. For services we receive that are either not distinct from the sale of the product or for which we cannot reasonably estimate the fair value, we classify the costs for such services as a reduction of product sales. To the extent that the services we receive are distinct from the sale of the product, we classify the costs for such services as selling, general and administration, or SG&A, expenses.

Product returns: Our U.S. customer has return rights and the wholesalers have limited return rights primarily related to the product’s expiration date. We estimate the amount of product sales that our customer may return. We record our return estimate as an accrued refund liability on our condensed consolidated balance sheet with a corresponding offset reducing our product sales in the same period we recognize the related sale. Based on our distribution model for product sales, contractual inventory limits with our customer and wholesalers and the price of the product, we believe we will have minimal returns. Our EU customers only take title to the product after they receive an order from a hospital or pharmacy and therefore they do not maintain excess inventory levels of our products. Accordingly, we have limited return risk in the EU and we do not estimate returns in the EU.

Other incentives: In the U.S., we estimate reserves for other incentives including co-payment assistance we provide to patients with commercial insurance who have coverage and reside in states that allow co-payment assistance. We record a reserve for the amount we estimate we will pay for co-payment assistance. We base our reserve on the number of estimated claims and our estimate of the cost per claim related to product sales that we have recognized as revenue. We record our other incentive reserve estimates as an accrued liability on our condensed consolidated balance sheet with a corresponding offset reducing our product sales in the same period we recognize the related sale.

Research and development revenue under collaboration agreements:



Upfront payments



When we enter into a collaboration agreement with 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. For example, under our collaboration agreement with Roche to develop IONIS-FB-LRx for the treatment of complement-mediated diseases, we received a $75 million upfront payment in the fourth quarter of 2018. We allocated the upfront payment to our single performance obligation, R&D services. We are amortizing the $75 million upfront payment using an input method over the estimated period of time we are providing R&D services.


Milestone payments



We are required to 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 there is considerable uncertainty in the research and development processes that trigger these payments under our collaboration agreements. 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, in the second quarter of 2019, we achieved a $7.5 million milestone payment from Biogen when we advanced a new target for an unidentified neurological disease under our 2018 strategic neurology collaboration. We added this payment to the transaction price and allocated it to our R&D services performance obligation. We are recognizing revenue related to this milestone payment over our estimated period of performance.



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. For example, in the third quarter of 2019, we recognized an $8 million milestone payment when Biogen initiated a Phase 1/2 study of IONIS-LRRK2Rx (BIIB094) for the treatment of people with Parkinson’s disease. We concluded that the milestone payment was not related to our R&D services performance obligation. Therefore, we recognized the milestone payment in full in the third quarter of 2019.



License fees



We generally recognize as revenue the total amount we determine to be the 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. For example, in the third quarter of 2019, we earned a $25 million license fee when GSK licensed our HBV program from us.


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. For example, in the second quarter of 2019, we earned a $20 million sublicense fee when Alnylam Pharmaceuticals sublicensed our technology to Regeneron Pharmaceuticals.


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 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 at their 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 adjustment.


13



For example, in May 2015, we entered into an exclusive license agreement with Bayer to develop and commercialize IONIS-FXIRx for the prevention of thrombosis. As part of the agreement, Bayer paid us a $100 million upfront payment. At the onset of the agreement, we were responsible for completing a Phase 2 study of IONIS-FXIRx in people with end-stage renal disease on hemodialysis and for providing an initial supply of API. In February 2017, we amended our agreement with Bayer to advance IONIS-FXIRx and to initiate development of IONIS-FXI-LRx, which Bayer licensed. As part of the 2017 amendment, Bayer paid us $75 million. We are also eligible to receive milestone payments and tiered royalties on gross margins of IONIS-FXIRx and IONIS-FXI-LRx. Under the 2017 amendment, we concluded we had a new agreement with 3 performance obligations. These performance obligations were to deliver the license of IONIS-FXI-LRx, to provide R&D services and to deliver API. We allocated the $75 million transaction price to these performance obligations. Refer to Note 7, Collaborative Arrangements and Licensing Agreements, for further discussion of our accounting treatment for our Bayer collaboration.


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.


For example, in the second quarter of 2018, we entered into 2 separate agreements with Biogen at the same time: a new strategic neurology collaboration agreement and a stock purchase agreement, or SPA. We evaluated the Biogen agreements to determine whether we should treat the agreements separately or combine them. We considered that the agreements 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.


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 contract receivable to be unconditional. We typically receive payment within one quarter of billing our partner or customer.


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 on our condensed consolidated balance sheet.


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 on our condensed consolidated balance sheet. During the three months ended September 30, 2019 and 2018, we recognized $30.3 million and $37.2 million of revenue from amounts that were in our beginning deferred revenue balance for each respective period. During the nine months ended September 30, 2019 and 2018, we recognized $103.5 million and $80.4 million of revenue from amounts that were in our beginning deferred revenue balance for each respective period. For further discussion, refer to our revenue recognition policy above.


Cost of Products Sold


Our cost of products sold includes 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 products sold. Prior to obtaining regulatory approval of TEGSEDI in July 2018 and WAYLIVRA in May 2019, we expensed a significant portion of the costs we incurred to produce the supply for each medicine we are using in the commercial launch as research and development expense. We previously expensed $0.2 million and $0.5 million of costs to produce our products related to the product sales revenue we recognized in the three and nine months ended September 30, 2019, respectively.

Noncontrolling Interest in Akcea Therapeutics, Inc.



Prior to Akcea’s IPO in July 2017, we owned 100 percent of Akcea. From the closing of Akcea’s IPO in July 2017 through mid-April 2018, we owned approximately 68 percent of Akcea. In the second, third and fourth quarters of 2018, we received additional shares of Akcea’s stock related to our license of TEGSEDI and AKCEA-TTR-LRx to Akcea, increasing our ownership percentage to approximately 75 percent. In the first quarter of 2019, we received 2.8 million shares of Akcea common stock as payment for the sublicense fee Akcea owed us when Novartis licensed AKCEA-APO(a)-LRx, increasing our ownership to approximately 76 percent at March 31, 2019. At September 30, 2019, our ownership in Akcea was approximately 75 percent. In the fourth quarter of 2019, we expect to receive an additional 6.9 million shares of Akcea common stock as payment for the sublicense fee Akcea owes us for Pfizer’s license of AKCEA-ANGPTL3-LRx. We reflect changes in our ownership of Akcea in our financial statements as an adjustment to noncontrolling interest in the period the change occurs. The shares third parties own represent an interest in Akcea’s equity that is not controlled by us. However, as we continue to maintain overall control of Akcea through our voting interest, we reflect the assets, liabilities and results of operations of Akcea in our condensed consolidated financial statements. We reflect the noncontrolling interest attributable to other owners of Akcea’s common stock in a separate line on the statement of operations and a separate line within stockholders’ equity in our condensed consolidated balance sheet. In addition, we record a noncontrolling interest adjustment to account for the stock options Akcea grants, which if exercised, will dilute our ownership in Akcea. This adjustment is 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.


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. 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 September 30, 2019, we held equity investments in 2 publicly held companies, ProQR Therapeutics N.V., or ProQR, and Antisense Therapeutics Limited, or ATL. We also held equity investments in 4 privately-held companies, Atlantic Pharmaceuticals Limited, Dynacure SAS, Seventh Sense Biosystems and Suzhou Ribo Life Science Co, Ltd.


Inventory Valuation



We reflect our inventory on our condensed consolidated balance sheet at the lower of cost or market 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. 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.


We obtained the first regulatory approval for TEGSEDI in July 2018 and in May 2019 for WAYLIVRA. At September 30, 2019, our physical inventory for TEGSEDI and WAYLIVRA included API that we produced prior to when we obtained regulatory approval. As such, this API has no cost basis as we had previously expensed the costs as R&D expenses.


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. We did 0t record any material inventory write-offs for the nine months ended September 30, 2019. Total inventory was $19.4 million and $8.6 million as of September 30, 2019 and December 31, 2018, respectively.

Leases



Topic 842 Adoption



In February 2016, the Financial Accounting Standards Board, or FASB, issued amended accounting guidance related to lease accounting. This guidance supersedes the lease requirements we previously followed in Accounting Standards Codification, or ASC, Topic 840, Leases, or Topic 840, and created a new lease accounting standard, Topic 842, Leases, or Topic 842. Under Topic 842, an entity will record on its balance sheet all leases with a term longer than one year. Further, an entity will record a liability with a value equal to the present value of payments it will make over the life of the lease (lease liability) and an asset representing the underlying leased asset (right-of-use asset). The new accounting guidance requires entities to determine if its leases are operating or financing leases. Entities will recognize expense for operating leases on a straight-line basis as an operating expense. If an entity determines a lease is a financing lease, it will record both interest and amortization expense and generally the expense will be higher in the earlier periods of the lease. We adopted Topic 842 on January 1, 2019 and adjusted our opening balance sheet on that date for our right-of-use operating lease assets and operating lease liabilities. At adoption, we recorded $13.5 million in right-of-use operating lease assets and $18.5 million in operating lease liabilities, of which we classified $2 million as a current liability. We adopted Topic 842 using the available practical expedients permitted under the transition guidance within the new standard, which among other things, allowed us to carry forward the historical lease classification of those leases we had in place as of January 1, 2019. The adoption did not have an impact on our condensed consolidated statement of operations.



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 on our condensed consolidated balance sheet 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. We determined the lease term at the inception of the lease, and in certain cases our lease term could include renewal options if we concluded we were reasonably certain that we will exercise the renewal option.



As our current leases do not provide an interest rate implicit in the lease, we used our or Akcea’s incremental borrowing rate, based on the information available on the date we adopted Topic 842 or as of the lease inception date in determining the present value of future payments. Our right-of-use operating lease asset also includes any lease payments we made and excludes any tenant improvement allowances we received. We recognize rent expense for our minimum lease payments on a straight-line basis over the expected term of our lease. We recognize period expenses, such as common area maintenance expenses, in the period we incur the expense.

Research, Development and Patent Expenses


Our research and development expenses include wages, benefits, facilities, supplies, external services, clinical trial and manufacturing costs 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 on our condensed consolidated balance sheet and we expense them as the services are provided.


We capitalize costs consisting principally of outside legal costs and filing fees related to obtaining patents. We amortize patent costs over the useful life of the patent, beginning with the date the United States Patent and Trademark Office, or foreign equivalent, issues the patent. We review our capitalized patent costs regularly to ensure that they include costs for patents and patent applications that have future value. We evaluate patents and patent applications that we are not actively pursuing and write off any associated costs.


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.


On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act of 2017, or the Tax Act. The Tax Act created a new requirement on global intangible low-taxed income, or GILTI, earned by foreign subsidiaries for tax years beginning on or after January 1, 2018. The GILTI provisions require foreign subsidiary earnings in excess of an allowable return on the foreign subsidiary’s assets to be included in our U.S. income tax return. Under U.S. GAAP, we are permitted to make an accounting policy election to either treat taxes due on future inclusions in U.S. taxable income related to GILTI as a current-period expense when incurred or to factor such amounts into our measurement of deferred taxes. We have made the election to account for GILTI as a component of current taxes incurred rather than as a component of deferred taxes.

16



Long-lived Assets



We evaluate long-lived assets, which include property, plant and equipment, right-of-use operating lease assets and patent costs acquired from third parties, 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.


Use of Estimates



The preparation of condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States requires us to make estimates and assumptions that affect the amounts reported in our condensed consolidated financial statements and accompanying notes. Actual results could differ from those estimates.


Basic and Diluted Net Income (Loss) Per Share


Basic net income (loss) per share



We compute basic net income (loss) per share by dividing the total net income (loss) attributable to our common stockholders by our weighted-average number of common shares outstanding during the period.



The calculation of total net income (loss) attributable to our common stockholders for the three and nine months ended September 30, 2019 and 2018 considered our net income 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 loss per share by the weighted average shares we owned in Akcea during the period. As a result of this calculation, our total net income (loss) available to Ionis common stockholders for the calculation of net income (loss) per share is different than net income (loss) attributable to Ionis Pharmaceuticals, Inc. common stockholders in the condensed consolidated statements of operations.


Our basic net income per share for the three months ended September 30, 2019, was calculated as follows (in thousands, except per share amounts):


Three months ended September 30, 2019

Dilutive net income (loss per share)


For the three and nine months ended September 30, 2019, we had net income available to Ionis common stockholders. As a result, we computed diluted net income per share using the weighted-average number of common shares and dilutive common equivalent shares outstanding during the period.


We calculated our diluted net income per share for the three months ended September 30, 2019 as follows (in thousands except per share amounts):

For the three and nine months ended September 30, 2019, the calculation excluded the 1 percent notes because the effect on diluted earnings per share was anti-dilutive.

18



For the three and nine months ended September 30, 2018, 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 from the following would have had an anti-dilutive effect on net loss per share:


1 percent convertible senior notes;
Dilutive stock options;
Unvested restricted stock units; and
Employee Stock Purchase Plan, or ESPP.


Convertible Debt



We account for convertible debt instruments that may be settled in cash upon conversion (including partial cash settlement) by separating the liability and equity components of the instruments in a manner that reflects our nonconvertible debt borrowing rate. We determine the carrying amount of the liability component by measuring the fair value of similar debt instruments that do not have the conversion feature. If no similar debt instrument exists, we estimate fair value by using assumptions that market participants would use in pricing a debt instrument, including market interest rates, credit standing, yield curves and volatilities. To determine the fair value of the debt component we are required to use accounting estimates and assumptions. These estimates and assumptions are judgmental in nature and could have a significant impact on the determination of the debt component, and the associated non-cash interest expense.



We assigned a value to the debt component of our convertible notes equal to the estimated fair value of similar debt instruments without the conversion feature, which resulted in us recording our debt at a discount. We are amortizing our debt issuance costs and debt discount over the life of the convertible notes as additional non-cash interest expense utilizing the effective interest method.


Segment Information



We have 2 operating segments, our Ionis Core segment and Akcea Therapeutics, our majority-owned affiliate. Akcea is a biopharmaceutical company focused on developing and commercializing medicines to treat patients with rare and serious diseases. We provide segment financial information and results for our Ionis Core segment and our Akcea Therapeutics segment based on the segregation of revenues and expenses that our chief decision maker reviews to assess operating performance and to make operating decisions. We allocate a portion of Ionis’ development, R&D support and general and administrative expenses to Akcea for work Ionis performs on behalf of Akcea.


Stock-based Compensation Expense



We measure stock-based compensation expense for equity-classified awards, principally related to stock options, restricted stock units, or RSUs, and stock purchase rights under our ESPP based on the estimated fair value of the award on the date of grant. We recognize the value of the portion of the award that we ultimately expect to vest as stock-based compensation expense over the requisite service period in our condensed consolidated statements of operations. We reduce stock-based compensation expense for estimated forfeitures at the time of grant and revise in subsequent periods if actual forfeitures differ from those estimates.


We use the Black-Scholes model to estimate the fair value of stock options granted and stock purchase rights under our ESPP. The expected term of stock options granted represents the period of time that we expect them to be outstanding. We estimate the expected term of options granted based on historical exercise patterns. For the nine months ended September 30, 2019 and 2018, we used the following weighted-average assumptions in our Black-Scholes calculations:


Ionis Employee Stock Options:

 
Nine Months Ended
September 30,
 
  2019  2018 
Risk-free interest rate  2.3%  2.3%

Risk-free interest rate  2.4%  1.8%
Dividend yield  0.0%  0.0%
Volatility  45.6%  47.3%
Expected life 6 months  6 months 


Ionis RSU’s:



The fair value of RSUs is based on the market price of our common stock on the date of grant. RSUs vest annually over a four-year period. The weighted-average grant date fair value of RSUs granted to employees for the nine months ended September 30, 2019 was $59.79 per share. The weighted-average grant date fair value of RSUs granted to our board of directors for the nine months ended September 30, 2019 was $64.65 per share.


In addition to our stock plans, Akcea has its own stock plan under which it grants stock options and RSUs and under which it derives its stock-based compensation expense. The following are the weighted-average Black-Scholes assumptions Akcea used under its plan for the nine months ended September 30, 2019 and 2018:



Akcea Employee Stock Options:

 
Nine Months Ended

The following table summarizes stock-based compensation expense for the three and nine months ended September 30, 2019 and 2018 (in thousands).


 
Three Months Ended
September 30,
  
Nine Months Ended

 2019  2018  2019  2018 
Cost of products sold $127  $  $383  $ 
Research, development and patent  23,744   18,780   71,935   57,698 
Selling, general and administrative  255   16,103   39,246   39,512 
Total non-cash stock-based compensation expense $24,126  $34,883  $111,564  $97,210 


In the third quarter of 2019, 3 Akcea executive officers terminated their employment and entered into separation agreements with Akcea. As a result, in the third quarter of 2019, Akcea reversed $19.1 million of stock-based compensation expense it had previously recognized related to the executive officers’ stock options and RSUs that were no longer going to vest.



As of September 30, 2019, total unrecognized estimated non-cash stock-based compensation expense related to non-vested stock options and RSUs was $143.9 million and $71.3 million, respectively. Our actual expenses may differ from these estimates because we will adjust our unrecognized non-cash stock-based compensation expense for future forfeitures. We expect to recognize the cost of non-cash stock-based compensation expense related to non-vested stock options and RSUs over a weighted average amortization period of 1.2 years and 1.6 years, respectively.


Amendment to Equity Plan


In June 2019, after receiving approval from our stockholders, we amended our 2011 Equity Incentive Plan to increase the total number of shares reserved for issuance under the plan from 16 million to 23 million shares.


Share Repurchase Program



In September 2019, our board of directors approved an initial share repurchase program of up to $125 million of our common stock. Our stock repurchase program has no expiration date. To date, we have 0t repurchased any shares of our common stock.


Impact of Recently Issued Accounting Standards



In June 2016, the FASB issued guidance that changes the measurement of credit losses for most financial assets and certain other instruments. If we have credit losses, this updated guidance requires us to record allowances for these instruments under a new expected credit loss model. This model requires us to estimate the expected credit loss of an instrument over its lifetime, which represents the portion of the amortized cost basis we do not expect to collect. The new guidance requires us to remeasure our allowance in each reporting period we have credit losses. The new standard is effective for annual and interim periods beginning after December 15, 2019. Early adoption is permitted for periods beginning after December 15, 2018. When we adopt the new standard, we will make any adjustments to beginning balances through a cumulative-effect adjustment to accumulated deficit on that date. We plan to adopt this guidance on January 1, 2020. We do not anticipate this guidance will have a significant impact on our condensed consolidated financial statements and disclosures.


In August 2018, the FASB issued clarifying guidance on how to account for implementation costs related to cloud-servicing arrangements. The guidance states that if these fees qualify to be capitalized and amortized over the service period, they need to be expensed in the same line item as the service expense and recognized in the same balance sheet category. The update can be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The updated guidance is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. We plan to adopt this guidance on January 1, 2020 on a prospective basis. We do not anticipate this guidance will have a significant impact on our condensed consolidated financial statements and disclosures.



In August 2018, the FASB updated its disclosure requirements related to Level 1, 2 and 3 fair value measurements. The update included deletion and modification of certain disclosure requirements and additional disclosure related to Level 3 measurements. The guidance is effective for fiscal years beginning after December 31, 2019 and early adoption is permitted. We adopted this updated guidance on January 1, 2019 and it did not have a significant impact on our disclosures.

21



In November 2018, the FASB issued clarifying guidance of the interaction between the collaboration accounting guidance and the new revenue recognition guidance we adopted on January 1, 2018 (Topic 606). Below is the clarifying guidance and how we will implement it (in italics):


1)When a participant is considered a customer in a collaborative arrangement, all of the associated accounting under Topic 606 should be applied
We will apply all of the associated accounting under Topic 606 when we determine a participant in a collaborative arrangement is a customer
2)Adds “unit of account” concept to collaboration accounting guidance to align with Topic 606. The “unit of account” concept is used to determine if revenue is recognized or if a contra expense is recognized from consideration received under a collaboration
We will use the “unit of account” concept when we receive consideration under a collaborative arrangement to determine when we recognize revenue or a contra expense
3)The clarifying guidance precludes us from recognizing revenue under Topic 606 when we determine a transaction with a collaborative partner is not a customer and is not directly related to the sales to third parties
When we conclude a collaboration partner is not a customer and is not directly related to the sales to third parties, we will not recognize revenue for the transaction


The updated guidance is effective for public entities for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. We plan to adopt this guidance on January 1, 2020. We are currently assessing the effects it could have on our condensed consolidated financial statements and disclosures.


3.  Investments


As of September 30, 2019, we had invested our excess cash primarily in 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.


The following table summarizes the contract maturity of the available-for-sale securities we held as of September 30, 2019:

One year or less  69%
After one year but within two years  22%
After two years but within three years  9%
Total  100%


As illustrated above, at September 30, 2019, 91 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 September 30, 2019, we had an ownership interest of less than 20 percent in 4 private companies and 2 public companies with which we conduct business. The privately-held companies are Atlantic Pharmaceuticals Limited, Dynacure SAS, Seventh Sense Biosystems and Suzhou Ribo Life Science Co, Ltd. The publicly-traded companies are ProQR and ATL.

The following is a summary of our investments we consider to be temporarily impaired at September 30, 2019. 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.

4.  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-held 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 the majority 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 September 30, 2019 and December 31, 2018 that we regularly measure and carry at fair value. At September 30, 2019 and December 31, 2018, our ProQR investment was subject to trading restrictions that extend to the fourth quarter of 2019; as a result, we included a lack of marketability discount in valuing this investment, which is a Level 3 input. The amount we owned in ProQR did not change from December 31, 2018 to September 30, 2019. The tables below segregate each security type by the level within the fair value hierarchy of the valuation techniques we utilized to determine the respective securities’ fair value (in thousands):

Convertible Notes


Our 1 percent notes had a fair value of $783.7 million at September 30, 2019. 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.

5.  Operating 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 with an initial term ending in June 2021 and an option to extend the lease for up to 2 five-year periods.



We also lease additional office space and we sublease a portion of this space to Akcea. We lease this space under a non-cancelable operating lease with an initial term ending in June 2023 and an option to extend the lease for 1 five-year period. The sublease with Akcea is eliminated in our condensed consolidated financial statements.



Akcea entered into an operating lease agreement for office space located in Boston, Massachusetts for its new corporate headquarters in the second quarter of 2018. The lease commencement date was in August 2018 and Akcea took occupancy in September 2018. Akcea is 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, Akcea received a three-month free rent period, which commenced on August 15, 2018, and a tenant improvement allowance up to $3.8 million. Akcea provided the lessor with a letter of credit to secure its obligations under the lease in the initial amount of $2.4 million, to be reduced to $1.8 million on the third anniversary of the rent commencement date and to $1.2 million on the fifth anniversary of the rent commencement date if Akcea meets certain conditions set forth in the lease at each such time.



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.

Amounts related to our operating leases were as follows (dollar amounts in millions):



 At September 30, 2019 
    
Right-of-use operating lease assets (1) $13.0 
Operating lease liabilities (2) $17.7 
Weighted average remaining lease term 8.3 years 
Weighted average discount rate  7.5%


(1)Included in deposits and other assets on our condensed consolidated balance sheet.


(2)Current portion of $2.1 million was included in current portion of long-term obligations on our condensed consolidated balance sheet, with the difference included in long-term obligations.


During the nine months ended September 30, 2019, we paid $2.9 million of rent payments, which was included in operating activities in our condensed consolidated statement of cash flows.


As of September 30, 2019, the payments for our operating lease liabilities are as follows (in thousands):


 Operating Leases 
Remainder of 2019 $801 
Years ending December 31,    
2020  3,282 
2021  3,019 
2022  2,781 
2023  2,520 
Thereafter  11,861 
Total minimum lease payments  24,264 
Less:    
Imputed interest  (6,533)
Total operating lease liabilities $17,731 


Rent expense was $0.8 million and $1.0 million for the three months ended September 30, 2019 and 2018, respectively. Rent expense was $2.7 million and $1.8 million for the nine months ended September 30, 2019 and 2018, respectively.


6.  Income Taxes


We recorded an income tax benefit of $14.9 million and an income tax expense of $9.2 million for the three and nine months ended September 30, 2019, compared to income tax expense of $0.5 million and $0.8 million for the same periods in 2018, respectively. The tax benefit recorded for the three months ended September 30, 2019 varies from what we would have recorded using the U.S. federal statutory rate primarily due to a state tax benefit resulting from our combined state tax filings with Akcea, estimated R&D and orphan drug credits, excess tax benefits related to share-based compensation and a benefit related to a change in the estimated tax value of Akcea shares we received in 2018. The increase in our income tax expense for the nine months ended September 30, 2019, compared to the same period in 2018, was primarily due to our expectation that we will generate U.S. federal and state taxable income in 2019. We expect to utilize our deferred tax assets to partially offset our U.S. federal taxable income.

7.  Collaborative Arrangements and Licensing Agreements


Below, we have included our collaborations with substantive changes during the first nine months of 2019 from those included in Note 6 of our audited financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2018.


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. In December 2017, we entered into a collaboration with Biogen to identify new antisense medicines for the treatment of SMA. We and Biogen are currently developing 8 medicines under collaborations, including medicines to treat people with ALS, Alzheimer’s disease and Parkinson’s disease. In addition to these medicines, our collaborations with Biogen include a substantial research pipeline that addresses a broad range of neurological diseases. From inception through September 2019, we have received $2.3 billion from our Biogen collaborations, including $1 billion we received from Biogen in the second quarter of 2018 for our 2018 strategic neurology collaboration.


During the three and nine months ended September 30, 2019 and 2018, we earned the following revenue from our relationship with Biogen (in millions, except percentage amounts):


 
Three Months Ended
September 30,
  
Nine Months Ended
September 30,
 
  2019  2018  2019  2018 
SPINRAZA royalties (commercial revenue) $81.7  $70.0  $211.9  $167.7 
R&D revenue  25.5   34.8   81.9   66.9 
Total revenue from our relationship with Biogen $107.2  $104.8  $293.8  $234.6 
Percentage of total revenue  64%  72%  47%  58%


Neurology Collaborations



2018 Strategic Neurology



In the second quarter of 2019, we achieved 2 $7.5 million milestone payments from Biogen when we advanced 2 new targets for unidentified neurological diseases under this collaboration. 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. We are recognizing revenue for our R&D services performance obligation based on the percentage of completion. From inception through September 2019, we have included $582 million in payments in the transaction price for our R&D services performance obligation under this collaboration. We currently estimate we will satisfy our performance obligation in June 2028.



We will achieve the next payment of $7.5 million if Biogen designates another target under this collaboration.



2013 Strategic Neurology



In the third quarter of 2019, we achieved an $8 million milestone payment when Biogen initiated a Phase 1/2 study of ION859 (IONIS-LRRK2Rx) for the treatment of people with Parkinson’s disease under this collaboration. We concluded that this milestone payment was not related to our R&D services performance obligation. Therefore, we recognized the $8 million milestone payment in full in the third quarter of 2019 because we do not have any performance obligations related to this payment.



From inception through September 2019, we have included $145 million in total payments in the transaction price for our R&D services performance obligation under this collaboration that we are recognizing over our estimated period of performance. We are recognizing revenue as we perform services based on our effort to satisfy our performance obligation relative to the total effort expected to satisfy our performance obligation. In the third quarter of 2019, we updated our estimate of the total effort we expect to expend to satisfy our performance obligation. As of September 30, 2019, we have completed a significant portion of the research and development services. We expect to complete the remainder of our services in 2020. As a result, we recorded a cumulative catch up adjustment of $16.5 million to decrease revenue in the third quarter of 2019. We will recognize this amount over the estimated remaining period we will perform services.
27



2012 Neurology



In the second quarter of 2019, we achieved a $7.5 million milestone payment from Biogen when we advanced IONIS-MAPTRx for Alzheimer’s disease under this collaboration. This milestone payment did not create a new performance obligation because it is part of our performance obligation to conduct development of IONIS-MAPTRx. Therefore, we included the $7.5 million milestone payment in our transaction price for our IONIS-MAPTRx development performance obligation. We are recognizing revenue for our IONIS-MAPTRx development performance obligation based on the percentage of completion. From inception through September 2019, we have included $25.5 million in the transaction price for our IONIS-MAPTRx development performance obligation. We currently estimate we will satisfy our performance obligation in September 2020.



We also have a separate performance obligation to perform R&D services under this collaboration. We have 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. Biogen’s decision to accept the development candidate was not within our control. We were recognizing 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. Because Biogen accepted the development candidate, we recognized $6.3 million of accelerated revenue in the third quarter of 2019.



We will achieve the next payment of up to $10 million if we advance a program under this collaboration.



During the nine months of 2019, we did not have any changes to our performance obligations or the timing in which we expect to recognize revenue under our Biogen collaborations, except as noted above.


Our condensed consolidated balance sheet at September 30, 2019 and December 31, 2018 included deferred revenue of $532.4 million and $580.9 million, respectively, related to our relationship with Biogen.

Research, Development and Commercialization Partners


Bayer



In May 2015, we entered into an exclusive license agreement with Bayer to develop and commercialize our programs targeting FXI for the treatment of clotting disorders. In October 2019, Bayer decided it would advance IONIS-FXI-LRx following positive clinical results and we earned a $10 million milestone payment. At September 30, 2019, we determined that it was not probable that we could earn this milestone payment. As such, we did not recognize any revenue associated with it during the third quarter of 2019. Bayer is now responsible for all global development, regulatory and commercialization activities and costs for the FXI program. From inception through September 2019, we have received over $175 million from our Bayer collaboration, not including the $10 million milestone payment we earned in the fourth quarter of 2019.  We will achieve the next payment of $20 million when Bayer initiates a Phase 3 study under the FXI program.


GSK



In March 2010, we entered into an alliance with GSK using our antisense drug discovery platform to discover and develop new drugs against targets for rare and serious diseases, including infectious diseases and some conditions causing blindness. Our collaboration with GSK includes 2 drugs targeting hepatitis B virus, or HBV: IONIS-HBVRx and IONIS-HBV-LRx, which we designed to reduce the production of viral proteins associated with HBV infection. In the third quarter of 2019, following positive Phase 2 results, GSK licensed our HBV program, for which we earned a $25 million license fee. From inception through September 2019, we have received more than $164 million in payments under our collaboration with GSK, not including the $25 million license fee, which we expect to receive in the fourth quarter of 2019. We will achieve the next payment of $15 million when GSK initiates a Phase 3 study for a drug under this program.



We identified a new performance obligation when we granted GSK the license of the HBV program and assignment of related intellectual property rights in the third quarter of 2019 because the license is distinct from our other performance obligations. We recognized the $25 million license fee for the HBV program as revenue at that time because GSK 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 GSK.


During the three and nine months ended September 30, 2019 and 2018, we earned the following revenue from our relationship with GSK (in millions, except percentage amounts):


 
Three Months Ended
September 30,
  
Nine Months Ended

  2019  2018  2019  2018 
R&D revenue $25.1  $0.1  $25.3  $1.5 
Percentage of total revenue  15%  0%  4%  0%


We did 0t have any deferred revenue from our relationship with GSK at September 30, 2019 or December 31, 2018.

Roche



We have 2 collaborations with Roche, 1 to develop treatments for Huntington's disease, or HD, and 1 to develop IONIS-FB-LRx for the treatment of complement-mediated diseases. In December 2017, upon completion of the Phase 1/2 study of IONIS-HTTRx, Roche exercised its option to license IONIS-HTTRx and is now responsible for the global development, regulatory and commercialization activities for IONIS-HTTRx. In October 2018, we entered into a collaboration agreement with Roche to develop IONIS-FB-LRx for the treatment of complement-mediated diseases. The first indication we plan to pursue is the treatment of patients with geographic atrophy, or GA, the advanced stage of dry age-related macular degeneration, or AMD. We are responsible for conducting a Phase 2 study in patients with dry AMD. In addition, we plan to evaluate the medicine for a severe and rare renal indication. Roche has the option to license IONIS-FB-LRx at the completion of these studies. Upon licensing, Roche will be responsible for all further global development, regulatory and commercialization activities and costs. From inception through June 2019, we have received over $220 million from our Roche collaborations, including $35 million in milestone payments we earned in the first quarter of 2019 when Roche dosed the first patient in a Phase 3 study for IONIS-HTTRx. We will achieve the next payment of $15 million if Roche advances IONIS-HTTRx.


During the three and nine months ended September 30, 2019 and 2018, we earned the following revenue from our relationship with Roche (in millions, except percentage amounts):


 
Three Months Ended
September 30,
  
Nine Months Ended
September 30,
 
  2019  2018  2019  2018 
R&D revenue $4.7  $1.8  $52.3  $5.4 
Percentage of total revenue  3%  1%  8%  1%


Our revenue in the first nine months of 2019 included $35 million of milestone payments we earned when Roche dosed the first patient in the Phase 3 study of IONIS-HTTRx in the first quarter of 2019. We recognized these milestone payments in full in the first quarter of 2019 because we do not have any performance obligations related to these milestone payments, as Roche is conducting the Phase 3 study of IONIS-HTTRx.



During the first nine months of 2019, we did not have any changes to our performance obligations or the timing in which we expect to recognize revenue under our Roche collaborations.


Our condensed consolidated balance sheet at September 30, 2019 and December 31, 2018 included deferred revenue of $56.7 million and $72.6 million, respectively, related to our relationship with Roche.


Akcea Collaborations



The following collaboration agreements relate to Akcea, our majority owned affiliate. Our consolidated results include all the revenue earned and cash received under this collaboration agreement. We reflect the noncontrolling interest attributable to other owners of Akcea’s common stock in a separate line on the statement of operations and a separate line within stockholders’ equity in our condensed consolidated balance sheet.



Novartis


In January 2017, we and Akcea initiated a collaboration with Novartis to develop and commercialize AKCEA-APO(a)-LRx and AKCEA-APOCIII-LRx. Under the collaboration agreement, Novartis has an exclusive option to further develop and commercialize AKCEA-APO(a)-LRx and AKCEA-APOCIII-LRx. Akcea is responsible for completing a Phase 2 program, conducting an end-of-Phase 2 meeting with the FDA and providing initial quantities of API for each medicine. If Novartis exercises an option for either of these medicines, Novartis will be responsible for all further global development, regulatory and co-commercialization activities and costs for such medicine. In the first quarter of 2019, Novartis licensed AKCEA-APO(a)-LRx. Novartis is responsible for conducting and funding all future development, regulatory and commercialization activities for AKCEA-APO(a)-LRx, including a global pivotal cardiovascular outcomes study, for which planning and initiation activities are underway. From inception through September 2019, we have received over $343 million from our Novartis collaboration, including $150 million we earned from Novartis in the first quarter of 2019 for the license of AKCEA-APO(a)-LRx. Akcea paid us $75 million as a sublicense fee in 2.8 million shares of Akcea common stock.



We identified a new performance obligation when we granted Novartis the license of AKCEA-APO(a)-LRx in the first quarter of 2019 because the license is distinct from our other performance obligations. We recognized the $150 million license fee for AKCEA-APO(a)-LRx as revenue at that time because Novartis 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 Novartis.



Novartis has the option to purchase additional API of AKCEA-APO(a)-LRx in the future at agreed upon terms and conditions under our collaboration agreement. We identified a new performance obligation when we delivered additional AKCEA-APO(a)-LRx API to Novartis in the third quarter of 2019 because the delivery of the API is distinct from our other performance obligations. We recognized $5.5  million in revenue for the API we sold to Novartis in the third quarter of 2019.

29



Akcea is responsible for the development activities under this collaboration. As such, Akcea is recognizing the associated revenue in its statement of operations, and we reflect all of Akcea’s revenue in our consolidated results. Akcea pays us sublicense fees for payments that it receives under the collaboration and we recognize those fees as revenue in our Ionis Core operating segment results and Akcea recognizes the fees as R&D expense. In our consolidated results, we eliminate this sublicense revenue and expense. Any cash Akcea receives is included in our condensed consolidated balance sheet.


During the three and nine months ended September 30, 2019 and 2018, we earned the following revenue from our relationship with Novartis (in millions, except percentage amounts):


 
Three Months Ended
September 30,
  
Nine Months Ended
September 30,
 
  2019  2018  2019  2018 
R&D revenue $8.5  $7.2  $176.3  $42.7 
Percentage of total revenue  5%  5%  28%  10%


During the first nine months of 2019, we did not have any changes to our performance obligations, except as noted above, or the timing in which we expect to recognize revenue under our Novartis collaboration.



Our condensed consolidated balance sheet at September 30, 2019 and December 31, 2018 included deferred revenue of $10.8 million and $28.8 million, respectively, related to our relationship with Novartis.


Pfizer



In October 2019, Akcea initiated a collaboration with Pfizer for the license of AKCEA-ANGPTL3-LRx to treat people with cardiovascular and metabolic diseases. Akcea is currently conducting a Phase 2 study of AKCEA-ANGPTL3-LRx for the treatment of non-alcoholic fatty liver disease, or NAFLD. Pfizer is responsible for all development and regulatory activities and costs beyond those associated with the ongoing Phase 2 study.



Under the terms of the agreement, Akcea will receive a $250 million upfront license fee, upon closing the transaction, including receiving Hart-Scott Rodino clearance. Akcea is also eligible to receive development, regulatory and sales milestone payments of up to $1.3 billion and tiered royalties in the mid-teens to low-20 percent range on annual worldwide net sales. Akcea has retained the rights to co-commercialize AKCEA-ANGPTL3-LRx in the U.S. and certain additional markets. The license fee, milestone payments and royalties will be split equally between us and Akcea. Upon receipt of the upfront payment from Pfizer, Akcea expects to pay us its $125 million sublicense fee in 6.9 million shares of Akcea common stock.

8.  Segment Information


We have 2 reportable segments, Ionis Core and Akcea Therapeutics. At September 30, 2019 we owned approximately 75 percent of Akcea. Segment income (loss) from operations includes revenue less operating expenses attributable to each segment.



In our Ionis Core segment we are exploiting our antisense technology to generate a broad pipeline of first-in-class and/or best-in-class medicines for us and our partners. Our Ionis Core segment generates revenue from a multifaceted partnering strategy.


Akcea is a biopharmaceutical company focused on developing and commercializing medicines to treat patients with rare and serious diseases. Akcea generates revenue from TEGSEDI and WAYLIVRA product sales and from its collaborations.


The following tables show our segment revenue and income (loss) from operations for the three and nine months ended September 30, 2019 and 2018 (in thousands), respectively.

ITEM 2.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

In this Report on Form 10-Q, unless the context requires otherwise, “Ionis,” “Company,” “we,” “our,” and “us,” means Ionis Pharmaceuticals, Inc. and its majority owned affiliate, Akcea Therapeutics, Inc.

Forward-Looking Statements

In addition to historical information contained in this Report on Form 10-Q, the Report includes forward-looking statements regarding our business and the therapeutic and commercial potential of SPINRAZA (nusinersen), TEGSEDI (inotersen), WAYLIVRA (volanesorsen) and our technologies and products in development, including the business of Akcea Therapeutics, Inc., our majority-owned affiliate. Any statement describing our goals, expectations, financial or other projections, intentions or beliefs, is a forward-looking statement and should be considered an at-risk statement. Such statements are subject to certain risks and uncertainties, particularly those inherent in the process of discovering, developing and commercializing drugs that are safe and effective for use as human therapeutics, and in the endeavor of building a business around such drugs. Our forward-looking statements also involve assumptions that, if they never materialize or prove correct, could cause our results to differ materially from those expressed or implied by such forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, those discussed in this report and described in additional detail in our annual report on Form 10-K for the year ended December 31, 2018, which is on file with the U.S. Securities and Exchange Commission and is available from us, and those identified within Part II Item 1A. Risk Factors of this Report. Although our forward-looking statements reflect the good faith judgment of our management, these statements are based only on facts and factors currently known by us. As a result, you are cautioned not to rely on these forward-looking statements.

Overview

We are a leader in discovering and developing RNA-targeted therapeutics with sustained and growing revenues. We have created an efficient and broadly applicable drug discovery platform leveraging our expertise in antisense oligonucleotide therapeutics that we believe has fundamentally changed medicine and transformed the lives of people with devastating and often deadly diseases. Our large, diverse and advanced pipeline of over 40 first-in-class and/or best-in-class medicines addresses diseases across a broad range of therapeutic areas, targeting small, medium and large patient populations.

We have three commercial medicines approved in major markets around the world, SPINRAZA, TEGSEDI and WAYLIVRA. We have two medicines in Phase 3 studies, IONIS-HTTRx, for Huntington’s disease, and tofersen, for SOD1-ALS. We also have the potential for two more medicines to begin Phase 3 studies this year and additional medicines to begin Phase 3 studies by the end of 2020. These medicines, along with the more than 30 additional medicines in our pipeline, represent multiple potential drivers of value for years to come. We believe our efficient drug discovery platform, coupled with our innovation-centric business model, provides us with the flexibility to determine the optimal development and commercialization strategy to maximize the commercial opportunity for each of our medicines and ensure that we continue to produce transformative medicines for patients who need them. We believe we are positioned to drive substantial value for patients and shareholders.

As of September 2019, SPINRAZA was approved in over 50 countries around the world, and our partner Biogen, who is responsible for global SPINRAZA commercial activities, reported that more than 9,300 patients were on SPINRAZA therapy. SPINRAZA was the first approved medicine for the treatment of SMA. SPINRAZA is the established foundation-of-care for patients of all ages and all SMA types with this progressive, debilitating and often fatal genetic disease. SPINRAZA has been recognized with several Prix Galien awards. Through September 30, 2019, we have earned more than $560 million in commercial revenues from royalties on sales of SPINRAZA.

TEGSEDI, a once weekly, self-administered subcutaneous medicine, was approved in 2018 in the U.S., EU and Canada for the treatment of polyneuropathy caused by hATTR in adult patients. hATTR is a debilitating, progressive, and fatal disease. Akcea, our majority-owned affiliate focused on developing and commercializing medicines to treat patients with rare and serious diseases, launched TEGSEDI in the U.S. and EU in late 2018. Our aim is to make TEGSEDI available globally. We plan to achieve this in part through Akcea’s exclusive license agreement with PTC to commercialize TEGSEDI in Latin America. In October 2019, TEGSEDI was approved in Brazil. PTC announced that it intends to start launching activities for TEGSEDI immediately in Brazil. In conjunction with the approval, we earned $4 million from PTC. We have earned more than $30 million in TEGSEDI product sales since launching late last year.

WAYLIVRA, a self-administered, subcutaneous medicine, received conditional marketing authorization in May 2019 from the European Commission, or EC, as an adjunct to diet in adult patients with genetically confirmed FCS and at high risk for pancreatitis. Akcea launched WAYLIVRA in the EU in the third quarter of 2019 and is also focused on regulatory discussions in the U.S. and Canada. Akcea is leveraging its existing commercial infrastructure in Europe to market WAYLIVRA. Akcea is continuing to conduct open-label extension and early access programs. We and Akcea also conducted a study of WAYLIVRA for the treatment of people with familial partial lipodystrophy, or FPL. This study is called the BROADEN study. People with FPL lack subcutaneous adipose tissue and have abnormal subcutaneous fat distribution causing increased incidence of potentially life-threatening pancreatitis, diabetes, extreme insulin resistance and increased liver fat. In August 2019, we and Akcea announced topline results from the BROADEN study. In the study, WAYLIVRA met its primary endpoint demonstrating a statistically significant reduction in triglyceride levels. WAYLIVRA also met an important secondary endpoint with a statistically significant reduction in liver fat. Additionally, WAYLIVRA demonstrated a good safety and tolerability profile in patients with FPL in the BROADEN study. We and Akcea are continuing to evaluate the data from this study and are assessing next steps.

In addition to commercializing TEGSEDI and WAYLIVRA, Akcea has four other clinical-stage medicines in its pipeline: AKCEA-APO(a)-LRx (TQJ230), AKCEA-ANGPTL3-LRx, AKCEA-APOCIII-LRx and AKCEA-TTR-LRx, each of which could potentially treat multiple patient populations. Moving these medicines into Akcea ensures our core focus remains on innovation while enabling us to retain substantial value from these medicines. As of September 2019, we owned approximately 75 percent of Akcea.


In October 2019, Akcea initiated a collaboration with Pfizer for the license of AKCEA-ANGPTL3-LRx to treat people with cardiovascular and metabolic diseases. Under the terms of the agreement, Akcea will receive a $250 million upfront license fee, upon closing the transaction, including receiving Hart-Scott Rodino clearance. Akcea is also eligible to receive development, regulatory and sales milestone payments of up to $1.3 billion and tiered royalties in the mid-teens to low-20 percent range on annual worldwide net sales. Akcea will pay us 50 percent of the license fee, milestone payments and royalties. Pfizer is responsible for all development and regulatory activities and costs beyond those associated with the ongoing Phase 2 study. Upon receipt of the upfront payment from Pfizer, Akcea expects to pay us its $125 million sublicense fee in 6.9 million shares of Akcea common stock.

We are continuously advancing our technology and pipeline to provide the most value to patients. We have a pipeline of over 40 medicines that, like SPINRAZA, TEGSEDI and WAYLIVRA, have the potential to transform the treatment of diseases with no adequate treatment today. These medicines range from treatments for rare diseases with small patient populations to more common diseases afflicting millions of patients. Our pipeline covers a broad spectrum of therapeutic areas, such as cardiometabolic diseases, neurodegenerative diseases, cancer, severe and rare diseases and others. We believe our large and diverse pipeline contains many near-, mid- and longer-term growth drivers for the company.

We have a distinct partnering strategy based on each specific medicine and the expertise and resources we and our potential partners may bring to a collaboration. We may also develop and commercialize some medicines through affiliates. In general, these are medicines, like TEGSEDI and WAYLIVRA, that can benefit from our internal expertise and infrastructure, have manageable development plans and costs, and have the potential for initial rare disease indications. For other medicines, we may establish collaborations to advance the medicine. We have alliances with a cadre of leading global pharmaceutical companies that are working alongside us in developing our medicines, advancing our technology, preparing to commercialize our medicines and selling our medicines. Our partners include the following companies, among others: AstraZeneca, Bayer, Biogen, GSK, Janssen, Novartis, Pfizer and Roche. Our partners bring resources and expertise that augment and build upon our internal capabilities. We have the potential to earn over $20 billion in future milestone payments and licensing fees from our existing partnerships.

Financial Highlights

The following is a summary of our financial results (in thousands):

  Three Months Ended  Nine Months Ended 
  September 30,  September 30, 
  2019  2018  2019  2018 
Total revenue $167,892  $145,395  $628,918  $407,559 
Total operating expenses $165,369  $163,967  $523,689  $479,716 
Income (loss) from operations $2,523  $(18,572) $105,229  $(72,157)
Net income (loss) $18,432  $(20,365) $99,304  $(87,747)
Net income (loss) attributable to Ionis Pharmaceuticals, Inc. common stockholders $26,163  $(4,559) $109,730  $(46,335)

Our revenue for the first nine months of 2019 increased more than 50 percent, compared to the same period in 2018, primarily due to a more than 25 percent increase in commercial revenue from SPINRAZA royalties and increasing R&D revenues including the $150 million license fee we earned from Novartis when it licensed AKCEA-APO(a)-LRx.

Our operating expenses for the first nine months of 2019 increased, compared to the same period in 2018, principally due to our investments in the global launches of TEGSEDI and WAYLIVRA.

During the first nine months of 2019 we received more than $480 million in payments from our partners, including $230 million from Biogen, $156 million from Novartis, $36 million from Roche and $22 million from Alnylam. This is compared to more than $1.3 billion received in the first nine months of 2018, which included $1 billion from Biogen for our 2018 strategic neurology collaboration. Already in the fourth quarter of 2019, we have generated $260 million in payments from Pfizer and Bayer. We believe our strong financial position should enable us to continue to execute on our corporate goals throughout 2019 and beyond.

Critical Accounting Policies

We prepare our condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States. As such, we make certain estimates, judgments and assumptions that we believe are reasonable, based upon the information available to us. These judgments involve making estimates about the effect of matters that are inherently uncertain and may significantly impact our quarterly or annual results of operations and financial condition. Each quarter, our senior management reviews the development, selection and disclosure of such estimates with our audit committee of our board of directors. In the following paragraphs, we describe the specific risks associated with these critical accounting policies and we caution that future events rarely develop exactly as one may expect, and that best estimates may require adjustment.

The significant accounting policies, which we believe are the most critical to aid in fully understanding and evaluating our reported financial results, require the following:

Assessing the propriety of revenue recognition and associated deferred revenue;
Valuing premiums received under our collaborations;
Determining the appropriate cost estimates for unbilled preclinical studies and clinical development activities; and
Accounting for income taxes.

There have been no material changes to our critical accounting policies and estimates from the information provided in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our Annual Report on Form 10-K for the year ended December 31, 2018.

Results of Operations

Revenue

Our revenue was as follows (in thousands):

Product sales, net  11,945      28,563    
Licensing and other royalty revenue  2,082   12,746   11,638   14,232 
Total commercial revenue  95,699   82,756   252,085   181,975 
R&D revenue:                
Amortization from upfront payments  23,918   31,066   99,263   92,185 
Milestone payments  11,981   26,194   64,013   44,583 
License fees  25,523   1,649   198,212   64,227

Total R&D revenue  72,193   62,639   376,833   225,584 
Total revenue $167,892  $145,395  $628,918  $407,559 

We significantly increased both commercial and R&D revenue in the first nine months of 2019, compared to the same period in 2018. Commercial revenue increased over 35 percent primarily due to increased SPINRAZA royalties and TEGSEDI product sales. We also added WAYLIVRA product sales in the third quarter of 2019.

Our R&D revenue substantially increased in the first nine months of 2019 compared to the same period in 2018 primarily due to the following:

$150 million we earned from Novartis when Novartis licensed AKCEA-APO(a)-LRx;
$35 million we earned from Roche when Roche enrolled the first patient in the Phase 3 study of IONIS-HTTRx in patients with Huntington's disease;
$25 million we earned from GSK when GSK licensed our HBV program; and
$20 million we earned from Alnylam when Alnylam licensed our technology to Regeneron.

We expect to recognize revenue related Pfizer’s license of AKCEA-ANGPTL3-LRx in the fourth quarter of 2019. We will also recognize $10 million of revenue from Bayer for advancing IONIS-FXI-LRx in our fourth quarter.

Operating Expenses

To analyze and compare our results of operations to other similar companies, we believe it is important to exclude non-cash compensation expense related to equity awards from our operating expenses. We believe non-cash compensation expense related to equity awards is not indicative of our operating results or cash flows from our operations. Further, we internally evaluate the performance of our operations excluding it.

Our operating expenses by segment were as follows (in thousands):

  
Three Months Ended
September 30,
  
Nine Months Ended
September 30,
 
  2019  2018  2019  2018 
Ionis Core $82,667  $65,512  $243,920  $213,114 
Akcea Therapeutics  65,569   71,518   256,105   182,188 
Elimination of intercompany activity  (6,993)  (7,946)  (87,900)  (12,796)
Subtotal  141,243   129,084   412,125   382,506 
Non-cash compensation expense related to equity awards  24,126   34,883   111,564   97,210 
Total operating expenses $165,369  $163,967  $523,689  $479,716 

Our operating expenses, excluding non-cash compensation expense related to equity awards, increased for both the three and nine months ended September 30, 2019, compared to the same periods last year principally due to our investment in the global launches of TEGSEDI and WAYLIVRA. Stock-based compensation expense increased in the first nine months of 2019, compared to the same period last year primarily due to the increase in the grant date fair value of Akcea stock options granted and from stock option grants made to new employees as Akcea continued to build out its organization. This increase was offset by a reversal of $19.1 million of stock-based compensation expense for three terminated executive officers in the third quarter of 2019. The stock-based compensation expense reversal related to amounts we previously recognized related to these executive officers’ stock option and RSU grants that were no longer going to vest.

Cost of Products Sold

Our cost of products sold consisted of manufacturing costs, including certain fixed costs, transportation and freight, indirect overhead costs associated with the manufacturing and distribution of TEGSEDI and WAYLIVRA (beginning in the third quarter of 2019) and certain associated period costs. We do not expect our fixed costs will increase in direct correlation to TEGSEDI and WAYLIVRA product sales. Prior to the regulatory approval of TEGSEDI and WAYLIVRA, we expensed as R&D expense a significant portion of the cost of producing TEGSEDI and WAYLIVRA that Akcea is using in the commercial launches. We expect cost of products sold to increase as we deplete these inventories.

Our cost of products sold by segment were as follows (in thousands):

  September 30, 2019 
  Three Months Ended  Nine Months Ended 
Ionis Core $  $ 
Akcea Therapeutics  2,275   10,247 
Elimination of intercompany activity  (1,435)  (7,256)
Subtotal  840   2,991 
Non-cash compensation expense related to equity awards  127   382 
Total cost of products sold $967  $3,373 

We began recognizing cost of products sold in the third quarter of 2018 when TEGSEDI was approved and in the second quarter of 2019 when WAYLIVRA was approved. We previously expensed $0.2 million and $0.5 million of costs to produce the amount of TEGSEDI and WAYLIVRA we sold in the three and nine months ended September 30, 2019, respectively. We recognized these costs in prior periods because we incurred these costs before we obtained regulatory approval. We did not have cost of products sold in the first nine months of 2018. Akcea includes the amortization for milestone payments it made to us related to the U.S. and European approvals of TEGSEDI in its cost of products sold. Akcea is recognizing this amortization over TEGSEDI’s remaining estimated patent life. We eliminate this amortization in our consolidated results. All amounts exclude non-cash compensation expense related to equity awards.

Research, Development and Patent Expenses

Our research, development and patent expenses consist of expenses for antisense drug discovery, antisense drug development, manufacturing and operations and R&D support expenses.

Antisense Drug Discovery

We use our proprietary antisense technology to generate information about the function of genes and to determine the value of genes as drug discovery targets. We use this information to direct our own antisense drug discovery research, and that of our partners. Antisense drug discovery is also the function that is responsible for advancing our antisense core technology.

As we continue to advance our antisense technology, we are investing in our drug discovery programs to expand our and our partners’ drug pipelines.

Our antisense drug discovery expenses are part of our Ionis Core business segment and were as follows (in thousands):

Total antisense drug discovery expenses $21,087  $18,854  $62,202  $55,174 

Antisense drug discovery expenses were slightly higher for the three and nine months ended September 30, 2019, compared to the same periods in 2018, due to expenses we incurred related to advancing our research programs. All amounts exclude non-cash compensation expense related to equity awards.

Total antisense drug development expenses $57,549  $54,337  $177,805  $174,111 

In the first quarter of 2019, we received 2.8 million shares of Akcea common stock as payment for the $75 million sublicense fee Akcea owed us when Novartis licensed AKCEA-APO(a)-LRx. Akcea recognized the $75 million sublicense fee in its R&D development expenses. We eliminated this expense in our consolidated results. We expect to receive 6.9 million shares of Akcea common stock as payment for the $125 million sublicense fee Akcea will owe us once the Pfizer license of AKCEA-ANGPTL3-LRx closes. We expect Akcea will recognize the $125 million sublicense fee in its R&D expenses in the fourth quarter of 2019. We will eliminate this expense in our consolidated results.

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

Manufacturing and Operations

Expenditures in our manufacturing and operations function consist primarily of personnel costs, specialized chemicals for oligonucleotide manufacturing, laboratory supplies and outside services. Our manufacturing and operations function is responsible for providing drug supplies to antisense drug development, Akcea and our collaboration partners. Our manufacturing procedures include testing to satisfy good laboratory and good manufacturing practice requirements.

R&D Support

In our research, development and patent expenses, we include support costs such as rent, repair and maintenance for buildings and equipment, utilities, depreciation of laboratory equipment and facilities, amortization of our intellectual property, informatics costs, procurement costs and waste disposal costs. We call these costs R&D support expenses.

Selling, General and Administrative Expenses

Selling, general and administrative expenses include personnel and outside costs associated with the pre-commercialization and commercialization activities for our medicines and costs to support our company, our employees and our stockholders including, legal, human resources, investor relations, and finance. Additionally, we include in selling, general and administrative expenses such costs as rent, repair and maintenance of buildings and equipment, depreciation and utilities costs that we need to support the corporate functions listed above. We also include fees we owe under our in-licensing agreements related to SPINRAZA.

In the third quarter of 2018, Akcea began recognizing cost of products sold expenses after the approval of TEGSEDI.

Akcea’s development and patent expenses increased for the nine months ended September 30, 2019, compared to the same period in 2018 as a result of the one-time $75 million sublicense fee it paid to Ionis in Akcea common stock for Ionis' portion of the license fee Akcea received from Novartis in the first quarter of 2019. Excluding this one-time sublicense fee, Akcea's development expenses decreased primarily because Akcea has transitioned all further development of AKCEA-APO(a)-LRx to Novartis. In the fourth quarter of 2019, we expect Akcea’s development expenses to increase as a result of the one-time $125 million sublicense fee Akcea expects to pay to Ionis once the Pfizer license of AKCEA-ANGPTL3-LRx closes. The sublicense fees Akcea pays Ionis are eliminated in our consolidated results.

Akcea’s SG&A expenses increased in the three and nine months ended September 30, 2019 compared to the same periods in 2018, primarily due to Akcea’s commercialization of TEGSEDI and WAYLIVRA. For each period presented, we allocated a portion of Ionis’ SG&A expenses to Akcea for work we performed on Akcea’s behalf. We include these allocated expenses in Akcea’s SG&A expenses in the table above. All amounts exclude non-cash compensation expense related to equity awards.

In the first quarter of 2019, we began sharing profits and losses for TEGSEDI with Akcea under our TTR licensing agreement. As Akcea is the principal for all commercial activities related to the TTR License Agreement, Akcea records all activities related to TEGSEDI on a gross basis in its statement of operations based on the nature of the activity, including revenues, cost of products sold and sales and marketing expenses. Ionis’ share of the net profit/loss from commercializing TEGSEDI is separately presented on Akcea’s statement of operations on the line titled “Profit (loss) share for TEGSEDI commercialization activities”. Since TEGSEDI is currently generating a loss, this represents the amount Ionis owes Akcea under the licensing agreement for its share of the net loss of TEGSEDI commercialization activities during the period. For the three and nine months ended September 30, 2019, our share of losses for TEGSEDI commercialization activities was $8.9 million and $29.4 million, respectively. With the launch of WAYLIVRA in the third quarter of 2019, Akcea will now pay Ionis royalties on WAYLIVRA product sales. We eliminate these amounts in our consolidated results.

All amounts exclude non-cash compensation expense related to equity awards.

Investment Income

Investment income for the three and nine months ended September 30, 2019 was $13.1 million and $39.0 million, respectively, compared to $10.0 million and $18.7 million for the same periods in 2018. The increase in investment income was primarily due to our significantly higher average cash balance during the first nine months of 2019 compared to the same period in 2018.

Income Tax Benefit (Expense)

We recorded an income tax benefit of $14.9 million and an income tax expense of $9.2 million for the three and nine months ended September 30, 2019, compared to income tax expense of $0.5 million and $0.8 million for the same periods in 2018, respectively. The tax benefit recorded for the three months ended September 30, 2019 varies from what we would have recorded using the U.S. federal statutory rate primarily due to a state tax benefit resulting from our combined state tax filings with Akcea, estimated R&D and orphan drug credits, excess tax benefits related to share-based compensation and a benefit related to a change in the estimated tax value of Akcea shares we received in 2018. The increase in our income tax expense for the nine months ended September 30, 2019, compared to the same period in 2018, was primarily due to our expectation that we will generate U.S. federal and state taxable income in 2019. We expect to utilize our deferred tax assets to partially offset our U.S. federal taxable income.

Net Income (Loss)

We had a net loss of $18.4 million and net income of $99.3 million for the three and nine months ended September 30, 2019, respectively, compared to a net loss of $20.4 million and $87.7 million for the same periods in 2018. Our net income was primarily due to increased revenue year-over-year.

Net Loss Attributable to Noncontrolling Interest in Akcea Therapeutics, Inc.

At September 30, 2019, we owned approximately 75 percent of Akcea. The shares of Akcea that third parties own represent an interest in Akcea's equity that we do not control. However, because we continue to maintain overall control of Akcea through our voting interest, we reflect the assets, liabilities and results of operations of Akcea in our consolidated financial statements. We reflect the noncontrolling interest attributable to other owners of Akcea's common stock in a separate line called “Net loss attributable to noncontrolling interest in Akcea” on our statement of operations. Our noncontrolling interest in Akcea on our statement of operations for the three and nine months ended September 30, 2019, was a loss of $7.7 million and $10.4 million, respectively, compared to $15.8 million and $41.4 million for the same periods in 2018.

Net Income (Loss) Attributable to Ionis Pharmaceuticals, Inc. Common Stockholders and Net Income (Loss) per Share

We had net income attributable to our common stockholders’ of $26.2 million for the three months ended September 30, 2019, compared to a net loss attributable to our common stockholders’ of $4.6 million for the same period in 2018. For the nine months ended September 30, 2019 we reported net income attributable to our common stockholders of $109.7 million, compared to a net loss attributable to our common stockholders of $46.3 million for the same period in 2018. The increase was primarily due to increases in revenue.

For the three months ended September 30, 2019, basic and diluted net loss per share were $0.19 and $0.18, respectively, compared to $0.03 for the same period in 2018. For the nine months ended September 30, 2019, basic and diluted net income per share were $0.81 and $0.79, respectively, compared to $0.33 for the same period in 2018.

Liquidity and Capital Resources

We have financed our operations primarily from research and development collaborative agreements. We also finance our operations from commercial revenue from SPINRAZA royalties and product sales. From our inception through September 30, 2019, we have earned approximately $3.8 billion in revenue. We have also financed our operations through the sale of our equity securities and the issuance of long-term debt. From the time we were founded through September 30, 2019, we have raised net proceeds of approximately $1.8 billion from the sale of our equity securities, not including the $182.4 million Akcea received in net proceeds from its IPO in July 2017. Additionally, we have borrowed approximately $1.4 billion under long-term debt arrangements to finance a portion of our operations over the same time period.
41


At September 30, 2019, we had cash, cash equivalents and short-term investments of $2.2 billion and stockholders’ equity of $1.5 billion. In comparison, we had cash, cash equivalents and short-term investments of $2.1 billion and stockholders’ equity of $1.2 billion at December 31, 2018. Our cash, cash equivalents and short-term investments increased in the first nine months of 2019 primarily from payments we received from Biogen, Novartis and Roche. We expect to receive $260 million in payments we generated from Pfizer and Bayer so far in the fourth quarter of 2019.

In September 2019, our board of directors approved an initial share repurchase program of up to $125 million of our common stock. Our stock repurchase program has no expiration date. To date, we have not repurchased any shares of our common stock. We plan to make stock repurchases under this program over time in open market transactions. We may consider additional share repurchases in the future as part of our overall capital allocation strategy.

At September 30, 2019, we had consolidated working capital of $2.2 billion compared to $1.9 billion at December 31, 2018. As of September 30, 2019, our debt and other obligations totaled $763.4 million compared to $763.9 million at December 31, 2018. The increase in our debt and other obligations is from the operating lease liability we added to our balance sheet when we adopted the new accounting guidance for leases on January 1, 2019.

The following table summarizes our contractual obligations as of September 30, 2019. The table provides a breakdown of when obligations become due. We provide a more detailed description of the major components of our debt in the paragraphs following the table:

Contractual Obligations Payments Due by Period (in millions) 
(selected balances described below) Total  Less than 1 year  1-3 years  3-5 years  After 5 years 
Convertible senior notes (principal and interest payable) $702.6  $6.9  $695.7  $  $ 
Building mortgage payments $78.8  $2.4  $4.9  $6.9  $64.6 
Other obligations (principal and interest payable) $1.0  $0.1  $0.1  $0.1  $0.7 
Operating leases $24.3  $3.3  $5.9  $5.0  $10.1 
Total $806.7  $12.7  $706.6  $12.0  $75.4 

Our contractual obligations consist primarily of our convertible debt. In addition, we also have facility mortgages, facility leases and other obligations. Due to the uncertainty with respect to the timing of future cash flows associated with our unrecognized tax benefits, we are unable to make reasonably reliable estimates of the period of cash settlement with the respective taxing authorities. Therefore, we have excluded our gross unrecognized tax benefits from our contractual obligations table above.

1 Percent Convertible Senior Notes

In November 2014, we completed a $500 million offering of convertible senior notes, which mature in 2021 and bear interest at 1 percent. We used a substantial portion of the net proceeds from the issuance of the 1 percent convertible senior notes to repurchase $140 million in principal of our 2¾ percent convertible senior notes. As a result, the principal balance of the 2¾ percent notes following the repurchase in November 2014 was $61.2 million.

In December 2016, we issued an additional $185.5 million of 1 percent convertible senior notes in exchange for the redemption of $61.1 million of our 2¾ percent convertible senior notes. At September 30, 2019, we had a nominal amount of our 2¾ percent convertible senior notes outstanding. At September 30, 2019, we had the following 1 percent convertible senior notes outstanding (amounts in millions except price per share data):

  
1 Percent Convertible
Senior Notes
 
Outstanding principal balance $685.5 
Original issue date ($500 million of principal) November 2014 
Additional issue date ($185.5 million of principal) December 2016 
Maturity date November 2021 
Interest rate 1 percent 
Conversion price per share $66.81 
Total shares of common stock subject to conversion  10.3 

Interest is payable semi-annually. The notes are convertible under certain conditions, at the option of the note holders. We 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 1 percent notes prior to maturity, and no sinking fund is provided for them. Holders of the 1 percent notes may require us to purchase some or all of their notes upon the occurrence of certain fundamental changes, as set forth in the indenture governing the 1 percent notes, at a purchase price equal to 100 percent of the principal amount of the notes to be purchased, plus accrued and unpaid interest.

Financing Arrangement

In June 2015, we entered into a five-year revolving line of credit agreement with Morgan Stanley Private Bank, National Association, or Morgan Stanley, which we amended in February 2016. Under the amended credit agreement, Morgan Stanley provided a maximum of $30 million of revolving credit for general working capital purposes. During the third quarter of 2019, we paid off our total outstanding borrowings of $12.5 million under the agreement and subsequently terminated the agreement.

Research and Development and Manufacturing Facilities

In July 2017, we purchased the building that houses our primary R&D facility for $79.4 million. We purchased our manufacturing facility in July 2017 for $14.0 million. We financed the purchase of our primary R&D facility and manufacturing facility, with mortgage debt of $51.3 million and $9.1 million, respectively. Our primary R&D facility mortgage has 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 are only required to make interest payments. Both mortgages mature in August 2027.

Other Obligations

In addition to contractual obligations, we had outstanding purchase orders as of September 30, 2019 for the purchase of services, capital equipment and materials as part of our normal course of business.

We plan to continue to enter into collaborations with partners to provide for additional revenue to us and we may incur additional cash expenditures related to our obligations under any of the new agreements we may enter into. We currently intend to use our cash, cash equivalents and short-term investments to finance our activities. However, we may also pursue other financing alternatives, like issuing additional shares of our common stock, issuing debt instruments, refinancing our existing debt, or securing lines of credit. Whether we use our existing capital resources or choose to obtain financing will depend on various factors, including the future success of our business, the prevailing interest rate environment and the condition of financial markets generally.

ITEM 3.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to changes in interest rates primarily from our long-term debt arrangements and, secondarily, investments in certain short-term investments. We primarily invest our excess cash in highly liquid short-term investments of the U.S. Treasury and reputable financial institutions, corporations, and U.S. government agencies with strong credit ratings. We typically hold our investments for the duration of the term of the respective instrument. We do not utilize derivative financial instruments, derivative commodity instruments or other market risk sensitive instruments, positions or transactions to manage exposure to interest rate changes. Accordingly, we believe that, while the securities we hold are subject to changes in the financial standing of the issuer of such securities, we are not subject to any material risks arising from changes in interest rates, commodity prices, equity prices or other market changes that affect market risk sensitive instruments.

We are also exposed to changes in foreign currency exchange rates as we have foreign subsidiaries with functional currencies other than the U.S. dollar. We translate our subsidiaries’ functional currencies into our reporting currency, the U.S. dollar. As a result, our financial position, results of operations and cash flows can be affected by market fluctuations in the foreign currencies to U.S. dollar exchange rate, which are difficult to predict. A hypothetical 10 percent change in foreign exchange rates during any of the periods presented would not have had a material impact on our consolidated financial statements. Our business strategy incorporates potentially significant international expansion, particularly related to TEGSEDI and WAYLIVRA, therefore we expect that the impact of foreign currency exchange rate fluctuations may become more substantial in the future.

ITEM 4.CONTROLS AND PROCEDURES

We maintain disclosure controls and procedures that are designed to ensure that information we are required to disclose in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. We design and evaluate our disclosure controls and procedures recognizing that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance and not absolute assurance of achieving the desired control objectives.

As of our most recently completed fiscal year and as of the end of the period covered by this Quarterly Report on Form 10-Q, we carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer. Based on our evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of September 30, 2019. There have been no significant changes in our internal controls or in other factors that could significantly affect internal controls subsequent to September 30, 2019.
43


We also performed an evaluation of any changes in our internal controls over financial reporting that occurred during our last fiscal quarter and that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting. We conducted this evaluation under the supervision of and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer. That evaluation did not identify any changes in our internal controls over financial reporting that occurred during our latest fiscal quarter and that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

PART II — OTHER INFORMATION

ITEM 1.LEGAL PROCEEDINGS

Not applicable.

 ITEM 1A.RISK FACTORS

Investing in our securities involves a high degree of risk. You should consider carefully the following information about the risks described below, together with the other information contained in this report and in our other public filings in evaluating our business. If any of the following risks actually occur, our business could be materially harmed, and our financial condition and results of operations could be materially and adversely affected. As a result, the trading price of our securities could decline, and you might lose all or part of your investment. We have marked with an asterisk those risk factors that reflect substantive changes from the risk factors included in our Annual Report on Form 10-K for the year ended December 31, 2018.

Risks Associated with our Ionis Core and Akcea Therapeutics Businesses

If the market does not accept our medicines, including SPINRAZA, TEGSEDI and WAYLIVRA, we are not likely to generate revenues or become consistently profitable.

Even if our medicines are authorized for marketing, including SPINRAZA, TEGSEDI and WAYLIVRA, our success will depend upon the medical community, patients and third-party payors accepting our medicines as medically useful, cost-effective and safe. Even when the FDA or foreign regulatory authorities authorize our or our partners’ medicines for commercialization, doctors may not prescribe our medicines to treat patients. We and our partners may not successfully commercialize additional medicines.

Additionally, in many of the markets where we may sell our medicines in the future, if we cannot agree with the government regarding the price we can charge for our medicines, then we may not be able to sell our medicines in that market. Similarly, cost control initiatives by governments or third-party payors could decrease the price received for our medicines or increase patient coinsurance to a level that makes our medicines, including SPINRAZA, TEGSEDI and WAYLIVRA, unaffordable.

The degree of market acceptance for our medicines, including SPINRAZA, TEGSEDI and WAYLIVRA, depends upon a number of factors, including the:

receipt and scope of marketing authorizations;
establishment and demonstration in the medical and patient community of the efficacy and safety of our medicines and their potential advantages over competing products;
cost and effectiveness of our medicines compared to other available therapies;
patient convenience of the dosing regimen for our medicines; and
reimbursement policies of government and third-party payors.

Based on the profile of our medicines, physicians, patients, patient advocates, payors or the medical community in general may not accept and/or use any medicines that we may develop.

For example, the product label for TEGSEDI in the U.S. has a boxed warning for thrombocytopenia and glomerulonephritis, requires periodic blood and urine monitoring, and TEGSEDI has a Risk Evaluation and Mitigation Strategy, or REMS, program. Our main competition in the U.S. market for TEGSEDI is ONPATTRO (patisiran), marketed by Alnylam Pharmaceuticals, Inc. Although ONPATTRO requires intravenous administration and pre-treatment with steroids, it does not have a boxed warning or REMS. Additionally, in the clinical studies with WAYLIVRA, declines in platelet counts were observed in many patients and some patients discontinued the studies because of platelet declines. The product label for WAYLIVRA requires periodic blood monitoring. In each case, these label requirements could negatively affect our ability to attract and retain patients for these medicines. We believe that the enhanced monitoring we have implemented to support early detection and management of these issues can help manage these safety issues so that patients can continue treatment. Since implementation of the enhanced monitoring, serious platelet events have been infrequent. While we believe we and Akcea can better maintain patients on TEGSEDI and WAYLIVRA through patient-centric commercial approaches where we plan to have greater involvement with physicians and patients, if we cannot effectively maintain patients on TEGSEDI or WAYLIVRA, we may not be able to generate substantial revenue from TEGSEDI or WAYLIVRA sales.
44


If we or our partners fail to compete effectively, our medicines, including SPINRAZA, TEGSEDI and WAYLIVRA, will not contribute significant revenues.*

Our competitors engage in drug discovery throughout the world, are numerous, and include, among others, major pharmaceutical companies and specialized biopharmaceutical firms. Other companies engage in developing antisense technology. Our competitors may succeed in developing medicines that are:

priced lower than our medicines;
reimbursed more favorably by government and other third-party payors than our medicines;
safer than our medicines;
more effective than our medicines; or
more convenient to use than our medicines.

These competitive developments could make our medicines, including SPINRAZA, TEGSEDI and WAYLIVRA, obsolete or non-competitive.

Certain of our partners are pursuing other technologies or developing other medicines either on their own or in collaboration with others, including our competitors, to treat the same diseases our own collaborative programs target. Competition may negatively impact a partner’s focus on and commitment to our medicines and, as a result, could delay or otherwise negatively affect the commercialization of our medicines, including SPINRAZA, TEGSEDI and WAYLIVRA.

Many of our competitors have substantially greater financial, technical and human resources than we do. In addition, many of these competitors have significantly greater experience than we do in conducting preclinical testing and human clinical studies of new pharmaceutical products, in obtaining FDA and other regulatory authorizations of such products and in commercializing such products. Accordingly, our competitors may succeed in obtaining regulatory authorization for products earlier than we do. Marketing and sales capability is another factor relevant to the competitive position of our medicines, and we will primarily rely on our partners and Akcea to provide this capability.

There are several pharmaceutical and biotechnology companies engaged in the development or commercialization of products against targets that are also targets of products in our development pipeline. For example, ZOLGENSMA (approved in the U.S. for the treatment of pediatric patients less than two years of age with SMA), risdiplam (RG7916), reldesemtiv and firdapse could compete with SPINRAZA, and ONPATTRO (approved in the U.S. and Europe for a similar indication as TEGSEDI), VYNDAQEL and VYNDAMAX (approved in the U.S. for patients with both hereditary and wild type ATTR cardiomyopathy and in the EU for stage 1 hATTR amyloidosis with polyneuropathy), AG10, CRX-1008 and vutrisiran could compete with TEGSEDI. Also, metreleptin and gemcabene could compete with WAYLIVRA, while laquinimod, OMS823, selistat, VX15, WVE-120101 and WVE-120102 could compete with IONIS-HTTRx. Furthermore, arimoclomol could potentially compete with tofersen.

Following approval, our medicines, including SPINRAZA, TEGSEDI and WAYLIVRA could be subject to regulatory limitations. *

Following approval of a medicine, we and our partners must comply with comprehensive government regulations regarding the manufacture, marketing and distribution of drug products. We or our partners may not obtain the labeling claims necessary or desirable to successfully commercialize our drug products, including SPINRAZA, TEGSEDI and WAYLIVRA.

The FDA and foreign regulatory bodies have the authority to impose significant restrictions on an approved drug product through the product label and on advertising, promotional and distribution activities. For example:

in the U.S., TEGSEDI’s label contains a boxed warning for thrombocytopenia and glomerulonephritis;
TEGSEDI requires periodic blood and urine monitoring;
in the U.S., TEGSEDI is available only through a Risk Evaluation and Mitigation Strategy, or REMS, program; and
WAYLIVRA will require periodic blood monitoring.

In addition, when approved, the FDA or a foreign regulatory authority may condition approval on the performance of post-approval clinical studies or patient monitoring, which could be time consuming and expensive. For example, in connection with the conditional marketing approval for WAYLIVRA in the EU, we are required to conduct a post-authorization safety study to evaluate the safety of WAYLIVRA on thrombocytopenia and bleeding in FCS patients taking WAYLIVRA. If the results of such post-marketing studies are not satisfactory, the FDA or a foreign regulatory authority may withdraw marketing authorization or may condition continued marketing on commitments from us or our partners that may be expensive and/or time consuming to fulfill.

If we or others identify side effects after any of our drug products are on the market, or if manufacturing problems occur subsequent to regulatory approval, we or our partners may lose regulatory approval, or we or our partners may need to conduct additional clinical studies and/or change the labeling of our drug products, including SPINRAZA, TEGSEDI and WAYLIVRA.
45


We depend on our collaboration with Biogen for the development and commercialization of SPINRAZA.

We have entered into a collaborative arrangement with Biogen to develop and commercialize SPINRAZA. We entered into this collaboration primarily to:

fund our development activities for SPINRAZA;
seek and obtain regulatory approvals for SPINRAZA; and
successfully commercialize SPINRAZA.

We are relying on Biogen to obtain additional regulatory approvals for SPINRAZA, and successfully commercialize SPINRAZA. In general, we cannot control the amount and timing of resources that Biogen devotes to our collaboration. If Biogen fails to further develop SPINRAZA, obtain additional regulatory approvals for SPINRAZA, or commercialize SPINRAZA, or if Biogen’s efforts are not effective, our business may be negatively affected.

Our collaboration with Biogen may not continue for various reasons. Biogen can terminate our collaboration at any time. If Biogen stops developing or commercializing SPINRAZA, we would have to seek or spend additional funding, and SPINRAZA’s commercialization may be harmed or delayed.

Our collaboration with Biogen may not result in the continued successful commercialization of SPINRAZA. If Biogen does not continue to successfully commercialize SPINRAZA, we will receive limited revenues for SPINRAZA.

If Akcea cannot optimize and maintain effective marketing and sales capabilities or enter into agreements with third parties to market and sell TEGSEDI and WAYLIVRA, we may not generate significant product revenue from TEGSEDI or WAYLIVRA.*

To successfully commercialize TEGSEDI and WAYLIVRA, Akcea must effectively manage its marketing, sales and distribution capabilities or make arrangements with third parties to perform these services. Akcea may not be successful in doing so. To commercialize TEGSEDI and WAYLIVRA in the initial indications Akcea is pursuing, Akcea will need to optimize and maintain a specialty sales force in each global region it expects to market TEGSEDI and WAYLIVRA, supported by case managers, reimbursement specialists, partnerships with specialty pharmacies, injection training, routine blood and urine monitoring and a medical affairs team. It will be expensive and time consuming for Akcea to maintain its own sales force and related compliance protocols to market TEGSEDI and WAYLIVRA. Akcea may never successfully optimize or manage this capability and any failure could preclude the successful commercialization of TEGSEDI and/or WAYLIVRA. Additionally, Akcea and its partners, if any, will have to compete with other companies to recruit, hire, train, manage and retain marketing and sales personnel.

Akcea incurred expenses prior to the launch of TEGSEDI and WAYLIVRA to integrate and manage the associated marketing and sales infrastructure. If regulatory requirements or other factors cause the commercial launch of TEGSEDI or WAYLIVRA to be less successful than expected, Akcea will have incurred expenses for having invested in these capabilities prior to realizing any significant revenue from sales of TEGSEDI or WAYLIVRA. Akcea’s sales force and marketing teams may not successfully commercialize TEGSEDI or WAYLIVRA.

Akcea may seek to further penetrate markets by expanding its sales force or through strategic partnerships with other pharmaceutical or biotechnology companies or third-party sales organizations. To the extent we and Akcea decide to rely on third parties to commercialize TEGSEDI or WAYLIVRA in a particular geographic market, such as the collaboration Akcea has with PTC Therapeutics to commercialize TEGSEDI and WAYLIVRA in Latin America, we may receive less revenue than if Akcea commercialized TEGSEDI or WAYLIVRA by itself. Further we would have less control over the sales efforts of any other third parties involved in commercializing TEGSEDI or WAYLIVRA.

Even though certain members of Akcea’s management team and other employees have experience commercializing drug products, Akcea has no prior experience marketing, selling or distributing drug products, and there are significant risks involved in building and managing a commercial infrastructure. If Akcea cannot effectively build and manage its distribution, medical affairs, market access, marketing and sales infrastructure, or find a suitable third party to perform such functions, the commercial launch and sales of TEGSEDI and WAYLIVRA may be delayed, less successful or precluded. Such events may result in decreased sales and lower revenue, which could have a material adverse effect on our business, prospects, financial condition and results of operations. In September 2019, Akcea announced several changes to its senior leadership team, including the departure of its Chief Executive Officer, President, and Chief Operating Officer and the appointment of two new Board members and an interim Chief Executive Officer. These transitions could impair Akcea’s ability to manage its business.

If government or other third-party payors fail to provide adequate coverage and payment rates for our medicines, including SPINRAZA, TEGSEDI and WAYLIVRA, our revenue will be limited.

In both domestic and foreign markets, sales of our current and future products will depend in part upon the availability of coverage and reimbursement from third-party payors. The majority of people in the U.S. who would fit within our target patient populations for our medicines have their healthcare supported by a combination of Medicare coverage, other government health programs such as Medicaid, managed care providers, private health insurers and other organizations. Coverage decisions may depend upon clinical and economic standards that disfavor new drug products when more established or lower cost therapeutic alternatives are already available or subsequently become available. Assuming coverage is approved, the resulting reimbursement payment rates might not be enough to make our medicines affordable.

Third-party payors, whether foreign or domestic, or governmental or commercial, are developing increasingly sophisticated methods of controlling healthcare costs. In addition, in the U.S., no uniform policy of coverage and reimbursement for drug products exists among third-party payors. Therefore, coverage and reimbursement for drug products can differ significantly from payor to payor. Further, we believe that future coverage and reimbursement will likely be subject to increased restrictions both in the U.S. and in international markets. For example, in the U.S., recent health reform measures have resulted in reductions in Medicare and other healthcare funding, and there have been several U.S. Congressional inquiries and proposed federal legislation designed to, among other things, reform government program reimbursement methodologies for drug products and bring more transparency to drug pricing. Third-party coverage and reimbursement for our products or medicines may not be available or adequate in either the U.S. or international markets, which would negatively affect the potential commercial success of our products, our revenue and our profits.

If Biogen cannot manufacture finished drug product for SPINRAZA or the post-launch supply of the active drug substance for SPINRAZA, SPINRAZA may not maintain commercial success.

Biogen is responsible for the long-term supply of both SPINRAZA drug substance and finished drug product. Biogen may not be able to reliably manufacture SPINRAZA drug substance and drug product to support the long-term commercialization of SPINRAZA. If Biogen cannot reliably manufacture SPINRAZA drug substance and drug product, SPINRAZA may not maintain commercial success, which will harm our ability to generate revenue.

If we or our partners fail to obtain regulatory approval for our medicines and additional approvals for SPINRAZA, TEGSEDI and WAYLIVRA, we or our partners cannot sell them in the applicable markets.*

We cannot guarantee that any of our medicines will be considered safe and effective, or will be approved for commercialization. In addition, we cannot guarantee that SPINRAZA, TEGSEDI and WAYLIVRA will be approved in additional markets or for additional indications. We and our partners must conduct time-consuming, extensive and costly clinical studies to show the safety and efficacy of each of our medicines before they can be approved for sale. We must conduct these studies in compliance with FDA regulations and with comparable regulations in other countries.

We and our partners may not obtain necessary regulatory approvals on a timely basis, if at all, for our medicines. It is possible that regulatory agencies will not approve our medicines for marketing or additional marketing authorizations for SPINRAZA, TEGSEDI or WAYLIVRA. If the FDA or another regulatory agency believes that we or our partners have not sufficiently demonstrated the safety or efficacy of any of our medicines, including SPINRAZA, TEGSEDI and WAYLIVRA, the agency will not approve the specific medicine or will require additional studies, which can be time consuming and expensive and which will delay or harm commercialization of the medicine. For example, Akcea received a CRL from the FDA and a preliminary notice of noncompliance withdrawal letter from Health Canada for WAYLIVRA. As result, Akcea may need to submit additional data to the FDA and Health Canada or conduct additional clinical studies before obtaining marketing authorization, which would be expensive and cause delays.

Failure to receive marketing authorization for our medicines, or failure to receive additional marketing authorizations for SPINRAZA, TEGSEDI or WAYLIVRA, or delays in these authorizations could prevent or delay commercial introduction of the medicine, and, as a result, could negatively impact our ability to generate revenue from product sales.

If the results of clinical testing indicate that any of our medicines are not suitable for commercial use, we may need to abandon one or more of our drug development programs.*

Drug discovery and development has inherent risks and the historical failure rate for drugs is high. Antisense medicines are a relatively new approach to therapeutics. If we cannot demonstrate that our medicines are safe and effective for human use, we may need to abandon one or more of our drug development programs.

In the past, we have invested in clinical studies of medicines that have not met the primary clinical end points in their Phase 3 studies. Similar results could occur in clinical studies for our medicines, including the study of WAYLIVRA in patients with FPL, the study of IONIS-HTTRx in patients with Huntington’s disease and the study of tofersen in adults with SOD1-ALS. If any of our medicines in clinical studies, including WAYLIVRA, IONIS-HTTRx and tofersen do not show sufficient efficacy in patients with the targeted indication, it could negatively impact our development and commercialization goals for these medicines and our stock price could decline.
47


Even if our medicines are successful in preclinical and human clinical studies, the medicines may not be successful in late-stage clinical studies.*

Successful results in preclinical or initial human clinical studies, including the Phase 2 results for some of our medicines in development, may not predict the results of subsequent clinical studies, including the study of WAYLIVRA in patients with FPL, the study of IONIS-HTTRx in patients with Huntington’s disease and the study of tofersen in adults with SOD1-ALS. There are a number of factors that could cause a clinical study to fail or be delayed, including:

the clinical study may produce negative or inconclusive results;
regulators may require that we hold, suspend or terminate clinical research for noncompliance with regulatory requirements;
we, our partners, the FDA or foreign regulatory authorities could suspend or terminate a clinical study due to adverse side effects of a medicine on subjects in the trial;
we may decide, or regulators may require us, to conduct additional preclinical testing or clinical studies;
enrollment in our clinical studies may be slower than we anticipate;
people who enroll in the clinical study may later drop out due to adverse events, a perception they are not benefiting from participating in the study, fatigue with the clinical study process or personal issues;
the cost of our clinical studies may be greater than we anticipate; and
the supply or quality of our medicines or other materials necessary to conduct our clinical studies may be insufficient, inadequate or delayed.

In addition, our current medicines, including SPINRAZA, TEGSEDI and WAYLIVRA, are chemically similar to each other. As a result, a safety observation we encounter with one of our medicines could have, or be perceived by a regulatory authority to have, an impact on a different medicine we are developing. This could cause the FDA and other regulators to ask questions or take actions that could harm or delay our ability to develop and commercialize our medicines or increase our costs. For example, the FDA or other regulatory agencies could request, among other things, any of the following regarding one of our medicines: additional information or commitments before we can start or continue a clinical study, protocol amendments, increased safety monitoring, additional product labeling information, and post-approval commitments. Similarly, we recently completed a study of WAYLIVRA in patients with FPL and we have an ongoing open-label extension study of WAYLIVRA in patients with FCS, an ongoing open-label extension study of TEGSEDI and expanded access programs for each medicine. Adverse events or results from these studies could negatively impact our current or planned marketing approval applications for WAYLIVRA or the commercial opportunity for each product.

Any failure or delay in the clinical studies, including the study of IONIS-HTTRx in patients with Huntington’s disease and the study of tofersen in adults with SOD1-ALS, could reduce the commercial potential or viability of our medicines.

If we cannot manufacture our medicines or contract with a third party to manufacture our medicines at costs that allow us to charge competitive prices to buyers, we cannot market our products profitably.

To successfully commercialize any of our medicines, we or our partner would need to establish large-scale commercial manufacturing capabilities either on our own or through a third-party manufacturer. We and Akcea will rely on third-party manufacturers to supply the drug substance and drug product for TEGSEDI and WAYLIVRA. In addition, as our drug development pipeline increases and matures, we will have a greater need for clinical trial and commercial manufacturing capacity. We have limited experience manufacturing pharmaceutical products of the chemical class represented by our medicines, called oligonucleotides, on a commercial scale for the systemic administration of a medicine. There are a small number of suppliers for certain capital equipment and raw materials that we use to manufacture our medicines, and some of these suppliers will need to increase their scale of production to meet our projected needs for commercial manufacturing. Further, we must continue to improve our manufacturing processes to allow us to reduce our drug costs. We may not be able to manufacture our medicines at a cost or in quantities necessary to make commercially successful products.

Also, manufacturers, including us, must adhere to the FDA’s current Good Manufacturing Practices regulations and similar regulations in foreign countries, which the applicable regulatory authorities enforce through facilities inspection programs. We and our contract manufacturers may not comply or maintain compliance with Good Manufacturing Practices, or similar foreign regulations. Non-compliance could significantly delay or prevent receipt of marketing authorization for our medicines, including authorizations for SPINRAZA, TEGSEDI and WAYLIVRA, or result in enforcement action after authorization that could limit the commercial success of our medicines, including SPINRAZA, TEGSEDI and WAYLIVRA.

48


We depend on third parties to conduct our clinical studies for our medicines and any failure of those parties to fulfill their obligations could adversely affect our development and commercialization plans.*

We depend on independent clinical investigators, contract research organizations and other third-party service providers to conduct our clinical studies for our medicines and expect to continue to do so in the future. For example, we use clinical research organizations, such as Icon Clinical Research Limited, INC Research Toronto, Inc. and Medpace for the clinical studies for our medicines, including TEGSEDI and WAYLIVRA. We rely heavily on these parties for successful execution of our clinical studies, but do not control many aspects of their activities. For example, the investigators are not our employees. However, we are responsible for ensuring that these third parties conduct each of our clinical studies in accordance with the general investigational plan and approved protocols for the study. Third parties may not complete activities on schedule or may not conduct our clinical studies in accordance with regulatory requirements or our stated protocols. The failure of these third parties to carry out their obligations or a termination of our relationship with these third parties could delay or prevent the development, marketing authorization and commercialization of our medicines or additional authorizations for SPINRAZA, TEGSEDI and WAYLIVRA.

Risks Associated with our Businesses as a Whole

We have incurred losses, and our business will suffer if we fail to consistently achieve profitability in the future.*

Because drug discovery and development requires substantial lead-time and money prior to commercialization, our expenses have generally exceeded our revenue since we were founded in January 1989. As of September 30, 2019, we had an accumulated deficit of approximately $0.9 billion and stockholders’ equity of approximately $1.5 billion. Most of our historical losses resulted from costs incurred in connection with our research and development programs and from selling, general and administrative costs associated with our operations. Most of our income has come from collaborative arrangements, including commercial revenue from royalties and R&D revenue, with additional income from research grants and the sale or licensing of our patents, as well as interest income. If we do not continue to earn substantial revenue, we may incur additional operating losses in the future. We may not successfully develop any additional products or achieve or sustain future profitability.

Our ability to use our net operating loss carryovers and certain other tax attributes may be limited.

Under the Internal Revenue Code of 1986, as amended, or the Code, a corporation is generally allowed a deduction for net operating losses, or NOLs, carried over from a prior taxable year. Under that provision, we can carryforward our NOLs to offset our future taxable income, if any, until such NOLs are used or expire. The same is true of other unused tax attributes, such as tax credits.

Under the Tax Cut and Jobs Act of 2017, or the Tax Act, federal net operating losses incurred in 2018 and in future years may be carried forward indefinitely, but the deductibility of such federal net operating losses is limited. It is uncertain if and to what extent various states will conform to the newly enacted federal tax law.

In addition, under Section 382 of the Code, and corresponding provisions of state law, if a corporation undergoes an “ownership change,” which is generally defined as a greater than 50 percent change, by value, in its equity ownership over a three-year period, the corporation’s ability to use its pre-change net operating loss carryforwards and other pre-change tax attributes to offset its post-change income or taxes may be limited. We may experience ownership changes in the future as a result of subsequent shifts in our stock ownership, some of which may be outside of our control. If an ownership change occurs and our ability to use our net operating loss carryforwards or other tax attributes is materially limited, it would harm our future operating results by effectively increasing our future tax obligations.

Since corporate partnering is a significant part of our strategy to fund the development and commercialization of our development programs, if any of our collaborative partners fail to fund our collaborative programs, or if we cannot obtain additional partners, we may have to delay or stop progress on our drug development programs.

To date, corporate partnering has played a significant role in our strategy to fund our development programs and to add key development resources. We plan to continue to rely on additional collaborative arrangements to develop and commercialize our unpartnered medicines. However, we may not be able to negotiate favorable collaborative arrangements for these drug programs. If we cannot continue to secure additional collaborative partners, our revenues could decrease and the development of our medicines could suffer.

Our corporate partners are developing and/or funding many of the medicines in our development pipeline. If any of these pharmaceutical companies stops developing and/or funding these medicines, our business could suffer and we may not have, or be willing to dedicate, the resources available to develop these medicines on our own.

Our collaborators can terminate their relationships with us under certain circumstances, many of which are outside of our control. For example, as part of a reprioritization of its pipeline and strategic review of its rare disease business, GSK declined its option on TEGSEDI and IONIS-FB-LRx.
49


Even with funding from corporate partners, if our partners do not effectively perform their obligations under our agreements with them, it would delay or stop the progress of our drug development and commercial programs.

In addition to receiving funding, we enter into collaborative arrangements with third parties to:

conduct clinical studies;
seek and obtain marketing authorization; and
manufacture, market and sell our medicines.

Once we have secured a collaborative arrangement to further develop and commercialize one of our drug development programs, such as our collaborations with AstraZeneca, Bayer, Biogen, GSK, Janssen, Novartis and Roche, these collaborations may not continue or result in commercialized medicines, or may not progress as quickly as we first anticipated.

For example, a collaborator such as AstraZeneca, Bayer, Biogen, GSK, Janssen, Novartis or Roche, could determine that it is in its financial interest to:

pursue alternative technologies or develop alternative products that may be competitive with the medicine that is part of the collaboration with us;
pursue higher-priority programs or change the focus of its own development programs; or
choose to devote fewer resources to our medicines than it does for its own medicines.

If any of these occur, it could affect our partner’s commitment to the collaboration with us and could delay or otherwise negatively affect the commercialization of our medicines, including SPINRAZA.

If we do not progress in our programs as anticipated, the price of our securities could decrease.

For planning purposes, we estimate and may disclose the timing of a variety of clinical, regulatory and other milestones, such as when we anticipate a certain medicine will enter the clinic, when we anticipate completing a clinical study, or when we anticipate filing an application for, or obtaining, marketing authorization. We base our estimates on present facts and a variety of assumptions. Many underlying assumptions are outside of our control. If we do not achieve milestones in accordance with our or our investors’ expectations, including milestones related to SPINRAZA, TEGSEDI and WAYLIVRA, the price of our securities could decrease.

If we cannot protect our patents or our other proprietary rights, others may compete more effectively against us.

Our success depends to a significant degree upon whether we can continue to develop and secure intellectual property rights to proprietary products and services. However, we may not receive issued patents on any of our pending patent applications in the U.S. or in other countries. In addition, the scope of any of our issued patents may not be sufficiently broad to provide us with a competitive advantage. Furthermore, other parties may successfully challenge, invalidate or circumvent our issued patents or patents licensed to us so that our patent rights do not create an effective competitive barrier or revenue source.

Intellectual property litigation could be expensive and prevent us from pursuing our programs.

From time to time we have to defend our intellectual property rights. If we are involved in an intellectual property dispute, we sometimes need to litigate to defend our rights or assert them against others. Disputes can involve arbitration, litigation or proceedings declared by the U.S. Patent and Trademark Office or the International Trade Commission or foreign patent authorities. Intellectual property litigation can be extremely expensive, and this expense, as well as the consequences should we not prevail, could seriously harm our business.

If a third party claims that our medicines or technology infringe its patents or other intellectual property rights, we may have to discontinue an important product or product line, alter our products and processes, pay license fees or cease certain activities. We may not be able to obtain a license to needed intellectual property on favorable terms, if at all. There are many patents issued or applied for in the biotechnology industry, and we may not be aware of patents or patent applications held by others that relate to our business. This is especially true since patent applications in the U.S. are filed confidentially for the first 18 months. Moreover, the validity and breadth of biotechnology patents involve complex legal and factual questions for which important legal issues remain.
50


If we fail to obtain timely funding, we may need to curtail or abandon some of our programs.*

Many of our medicines are undergoing clinical studies or are in the early stages of research and development. Most of our drug programs will require significant additional research, development, preclinical and/or clinical testing, marketing authorization and/or commitment of significant additional resources prior to their successful commercialization. As of September 30, 2019, we had cash, cash equivalents and short-term investments equal to approximately $2.2 billion. If we do not meet our goals to successfully commercialize our medicines, including SPINRAZA, TEGSEDI and WAYLIVRA, or to license our medicines and proprietary technologies, we will need additional funding in the future. Our future capital requirements will depend on many factors, such as the following:

successful commercialization for SPINRAZA, TEGSEDI and WAYLIVRA;
additional marketing approvals for WAYLIVRA and TEGSEDI;
the profile and launch timing of our medicines, including TEGSEDI and WAYLIVRA;
changes in existing collaborative relationships and our ability to establish and maintain additional collaborative arrangements;
continued scientific progress in our research, drug discovery and development programs;
the size of our programs and progress with preclinical and clinical studies;
the time and costs involved in obtaining marketing authorizations; and
competing technological and market developments, including the introduction by others of new therapies that address our markets.

If we need additional funds, we may need to raise them through public or private financing. Additional financing may not be available at all or on acceptable terms. If we raise additional funds by issuing equity securities, the shares of existing stockholders will be diluted and the price, as well as the price of our other securities, may decline. If adequate funds are not available or not available on acceptable terms, we may have to cut back on one or more of our research, drug discovery or development programs. Alternatively, we may obtain funds through arrangements with collaborative partners or others, which could require us to give up rights to certain of our technologies or medicines.

If our planned management transition is not successful our business could suffer.

In January 2020, Dr. Crooke, our founder and Chief Executive Officer, plans to transition from Chief Executive Officer to Executive Chairman of our Board of Directors. As Executive Chairman, Dr. Crooke will continue to be responsible for the activities of the board and will remain active in the company, providing strategic advice and continuing to participate in the scientific activities. Our board has selected Dr. Monia, who has been our Chief Operating Officer for the last year and a member of our team since our founding nearly 30 years ago, to serve as our Chief Executive Officer starting in January 2020. If this transition is not successful, our business could suffer.

The loss of key personnel, or the inability to attract and retain highly skilled personnel, could make it more difficult to run our business and reduce our likelihood of success.

We are dependent on the principal members of our management and scientific staff. We do not have employment agreements with any of our executive officers that would prevent them from leaving us. The loss of our management and key scientific employees might slow the achievement of important research and development goals. It is also critical to our success that we recruit and retain qualified scientific personnel to perform research and development work. We may not be able to attract and retain skilled and experienced scientific personnel on acceptable terms because of intense competition for experienced scientists among many pharmaceutical and health care companies, universities and non-profit research institutions. In addition, failure to succeed in clinical studies may make it more challenging to recruit and retain qualified scientific personnel.

If the price of our securities continues to be highly volatile, this could make it harder for you to liquidate your investment and could increase your risk of suffering a loss.*

The market price of our common stock, like that of the securities of many other biopharmaceutical companies, has been and is likely to continue to be highly volatile. These fluctuations in our common stock price may significantly affect the trading price of our securities. During the 12 months preceding September 30, 2019, the market price of our common stock ranged from $43.27 to $86.58 per share. Many factors can affect the market price of our securities, including, for example, fluctuations in our operating results, announcements of collaborations, clinical study results, technological innovations or new products being developed by us or our competitors, governmental regulation, marketing authorization, changes in payors’ reimbursement policies, developments in patent or other proprietary rights, public concern regarding the safety of our medicines and general market conditions.
51


We cannot guarantee that we will repurchase shares of common stock under our stock repurchase program or that we will repurchase shares of common stock at favorable prices.*

In September 2019, our board of directors authorized a program to repurchase up to $125 million of our common stock. We can provide no assurance that we will repurchase shares at favorable prices, if at all, as the amount and timing of share repurchases under such program are subject to capital availability and our determination that share repurchases are in the best interest of our shareholders and in compliance with all applicable laws and agreements. Our ability to repurchase shares will depend upon, among other factors, our financial condition, results of operations, cash balances and potential future capital requirements for strategic transactions. In addition, the share repurchase program could impact the trading price of our stock and increase volatility, and any announcement of a reduction in or discontinuance of repurchases by us under such program may result in a decrease in the trading price of our stock.

We are exposed to potential product liability claims, and insurance against these claims may not be available to us at a reasonable rate in the future or at all.

Our business exposes us to potential product liability risks that are inherent in the testing, manufacturing, marketing and sale of therapeutic products, including potential product liability claims related to SPINRAZA, TEGSEDI and WAYLIVRA. We have clinical study insurance coverage and commercial product liability insurance coverage. However, this insurance coverage may not be adequate to cover claims against us, or be available to us at an acceptable cost, if at all. Regardless of their merit or eventual outcome, product liability claims may result in decreased demand for our drug products, injury to our reputation, withdrawal of clinical study volunteers and loss of revenues. Thus, whether or not we are insured, a product liability claim or product recall may result in losses that could be material.

Because we use biological materials, hazardous materials, chemicals and radioactive compounds, if we do not comply with laws regulating the protection of the environment and health and human safety, our business could be adversely affected.

Our research, development and manufacturing activities involve the use of potentially harmful biological materials as well as materials, chemicals and various radioactive compounds that could be hazardous to human health and safety or the environment. We store most of these materials and various wastes resulting from their use at our facilities in Carlsbad, California pending ultimate use and disposal. We cannot completely eliminate the risk of contamination, which could cause:

interruption of our research, development and manufacturing efforts;
injury to our employees and others;
environmental damage resulting in costly clean up; and
liabilities under federal, state and local laws and regulations governing health and human safety, as well as the use, storage, handling and disposal of these materials and resultant waste products.

In such an event, we may be held liable for any resulting damages, and any liability could exceed our resources. Although we carry insurance in amounts and types that we consider commercially reasonable, we do not have insurance coverage for losses relating to an interruption of our research, development or manufacturing efforts caused by contamination, and the coverage or coverage limits of our insurance policies may not be adequate. If our losses exceed our insurance coverage, our financial condition would be affected.

If a natural or man-made disaster strikes our research, development or manufacturing facilities or otherwise affects our business, it could delay our progress developing and commercializing our medicines.

We manufacture our research and clinical supplies in a manufacturing facility located in Carlsbad, California. We manufacture the finished drug product for TEGSEDI and WAYLIVRA at third-party contract manufacturers. The facilities and the equipment we and our contract manufacturers use to research, develop and manufacture our medicines would be costly to replace and could require substantial lead time to repair or replace. Our facilities or our contract manufacturers may be harmed by natural or man-made disasters, including, without limitation, earthquakes, floods, fires and acts of terrorism; and if our facilities are affected by a disaster, our development and commercialization efforts would be delayed. Although we possess insurance for damage to our property and the disruption of our business from casualties, this insurance may not be sufficient to cover all of our potential losses and may not continue to be available to us on acceptable terms, or at all. In addition, our development and commercialization activities could be harmed or delayed by a shutdown of the U.S. government, including the FDA.

Provisions in our certificate of incorporation, other agreements and Delaware law may prevent stockholders from receiving a premium for their shares.

Our certificate of incorporation provides for classified terms for the members of our board of directors. Our certificate also includes a provision that requires at least 66 2/3 percent of our voting stockholders to approve a merger or certain other business transactions with, or proposed by, any holder of 15 percent or more of our voting stock, except in cases where certain directors approve the transaction or certain minimum price criteria and other procedural requirements are met.
52


Our certificate of incorporation also requires that any action required or permitted to be taken by our stockholders must be taken at a duly called annual or special meeting of stockholders and may not be taken by written consent. In addition, only our board of directors, chairman of the board or chief executive officer can call special meetings of our stockholders. We have in the past, and may in the future, implement a stockholders’ rights plan, also called a poison pill, which could make it uneconomical for a third party to acquire our company on a hostile basis. In addition, our board of directors has the authority to fix the rights and preferences of, and issue shares of preferred stock, which may have the effect of delaying or preventing a change in control of our company without action by our stockholders.

The provisions of our convertible senior notes could make it more difficult or more expensive for a third party to acquire us. Upon the occurrence of certain transactions constituting a fundamental change, holders of the notes will have the right, at their option, to require us to repurchase all of their notes or a portion of their notes, which may discourage certain types of transactions in which our stockholders might otherwise receive a premium for their shares over the then current market prices.

These provisions, as well as Delaware law, including Section 203 of the Delaware General Corporation Law, and other of our agreements, may discourage certain types of transactions in which our stockholders might otherwise receive a premium for their shares over then current market prices, and may limit the ability of our stockholders to approve transactions that they think may be in their best interests.

Future sales of our common stock in the public market could adversely affect the trading price of our securities.

Future sales of substantial amounts of our common stock in the public market, or the perception that such sales could occur, could adversely affect trading prices of our securities. For example, we may issue approximately 10.3 million shares of our common stock upon conversion of our convertible senior notes. The addition of any of these shares into the public market may have an adverse effect on the price of our securities.

Our business is subject to changing regulations for corporate governance and public disclosure that has increased both our costs and the risk of noncompliance.

Each year we are required to evaluate our internal controls systems in order to allow management to report on and our Independent Registered Public Accounting Firm to attest to, our internal controls as required by Section 404 of the Sarbanes-Oxley Act. As a result, we continue to incur additional expenses and divert our management’s time to comply with these regulations. In addition, if we cannot continue to comply with the requirements of Section 404 in a timely manner, we might be subject to sanctions or investigation by regulatory authorities, such as the SEC, the Public Company Accounting Oversight Board, or PCAOB, or The Nasdaq Global Select Market. Any such action could adversely affect our financial results and the market price of our common stock.

The SEC and other regulators have continued to adopt new rules and regulations and make additional changes to existing regulations that require our compliance. On July 21, 2010, the Dodd-Frank Wall Street Reform and Protection Act, or the Dodd-Frank Act, was enacted. There are significant corporate governance and executive compensation-related provisions in the Dodd-Frank Act that require the SEC to adopt, or where the SEC has adopted, additional rules and regulations in these areas such as “say on pay” and proxy access. Stockholder activism, the current political environment and the current high level of government intervention and regulatory reform may lead to substantial new regulations and disclosure obligations, which may lead to additional compliance costs and impact the manner in which we operate our business.

Changes in tax laws, regulations and treaties could affect our future taxable income.

A change in tax laws, treaties or regulations, or their interpretation, of any country in which we operate could materially affect us.

We could be subject to additional tax liabilities.

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

Negative conditions in the global credit markets and financial services and other industries may adversely affect our business.

The global credit markets, the financial services industry, the U.S. capital markets, and the U.S. economy as a whole have in the past experienced periods of substantial turmoil and uncertainty characterized by unprecedented intervention by the U.S. federal government and the failure, bankruptcy, or sale of various financial and other institutions. It is possible that a crisis in the global credit markets, the U.S. capital markets, the financial services industry or the U.S. economy may adversely affect our business, vendors and prospects, as well as our liquidity and financial condition. More specifically, our insurance carriers and insurance policies covering all aspects of our business may become financially unstable or may not be sufficient to cover any or all of our losses and may not continue to be available to us on acceptable terms, or at all.

We are dependent on information technology systems, infrastructure and data, which exposes us to data security risks.

We are dependent upon our own or third-party information technology systems, infrastructure and data, including mobile technologies, to operate our business. The multitude and complexity of our computer systems may make them vulnerable to service interruption or destruction, disruption of data integrity, malicious intrusion, or random attacks. Likewise, data privacy or security incidents or breaches by employees or others may pose a risk that sensitive data, including our intellectual property, trade secrets or personal information of our employees, patients, customers or other business partners may be exposed to unauthorized persons or to the public. Cyber-attacks are increasing in their frequency, sophistication and intensity. Cyber-attacks could include the deployment of harmful malware, denial-of-service, social engineering and other means to affect service reliability and threaten data confidentiality, integrity and availability. Our business partners face similar risks and any security breach of their systems could adversely affect our security posture. A security breach or privacy violation that leads to disclosure or modification of or prevents access to patient information, including personally identifiable information or protected health information, could harm our reputation, compel us to comply with federal and/or state breach notification laws and foreign law equivalents, subject us to mandatory corrective action, require us to verify the correctness of database contents and otherwise subject us to litigation or other liability under laws and regulations that protect personal data, any of which could disrupt our business and/or result in increased costs or loss of revenue. Moreover, the prevalent use of mobile devices that access confidential information increases the risk of data security breaches, which could lead to the loss of confidential information, trade secrets or other intellectual property. While we have invested, and continue to invest, in the protection of our data and information technology infrastructure, there can be no assurance that our efforts will prevent service interruptions, or identify breaches in our systems, that could adversely affect our business and operations and/or result in the loss of critical or sensitive information, which could result in financial, legal, business or reputational harm to us. In addition, our liability insurance may not be sufficient in type or amount to cover us against claims related to security breaches, cyber-attacks and other related breaches.
