Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Operations and Summary of Significant Accounting Policies	1. Description of Operations and Summary of Significant Accounting Policies Description of Operations Innoviva, Inc. (and where context requires, together with its subsidiaries referred to as “Innoviva”, the “Company”, or “we” and other similar pronouns) is a company with a portfolio of royalties and innovative healthcare assets. Our royalty portfolio contains respiratory assets partnered with Glaxo Group Limited (“GSK”), including RELVAR®/BREO® ELLIPTA® (fluticasone furoate/vilanterol, “FF/VI”) and ANORO® ELLIPTA® (umeclidinium bromide/ vilanterol, “UMEC/VI”), and up until July 2022, TRELEGY® ELLIPTA® (the combination FF/UMEC/VI). We sold our 15% ownership interest in Theravance Respiratory Company, LLC (“TRC”) on July 20, 2022, and are no longer entitled to receive royalties on sales of TRELEGY® ELLIPTA® products. Under the Long-Acting Beta2 Agonist (“LABA”) Collaboration Agreement, Innoviva is entitled to receive royalties from GSK on sales of RELVAR®/BREO® ELLIPTA® as follows: 15% on the first $3.0 billion of annual global net sales and 5% for all annual global net sales above $3.0 billion; and royalties from the sales of ANORO® ELLIPTA®, which tier upward at a range from 6.5% to 10%. We expanded our portfolio of royalties and innovative healthcare assets through the acquisition of Entasis Therapeutics Holdings Inc. (“Entasis”) on July 11, 2022 and the acquisition of La Jolla Pharmaceutical Company (“La Jolla”) on August 22, 2022. Our commercial and marketed products include GIAPREZA® (angiotensin II), approved to increase blood pressure in adults with septic or other distributive shock, and XERAVA® (eravacycline) for the treatment of complicated intra-abdominal infections in adults. Our development pipeline includes medicines for the treatment of bacterial infections, such as our lead asset sulbactam-durlobactam (“SUL-DUR”). As such, we have a wholly owned robust infectious disease and hospital operating platform, as well as other assets in these areas, such as a large equity stake in Armata Pharmaceuticals, a leader in bacteriophage development with potential use across a range of infectious and other serious diseases. We also have economic interests in other healthcare companies. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information. Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. The unaudited condensed consolidated financial statements have been prepared on the same basis as audited consolidated financial statements and, in our opinion, include all adjustments, consisting of all normal recurring adjustments, necessary for the fair presentation of our financial position, results of operations, comprehensive income and cash flows. The interim results are not necessarily indicative of the results of operations to be expected for the year ending December 31, 2023, or any other periods. The accompanying unaudited condensed consolidated financial statements include the accounts of Innoviva, our wholly-owned subsidiaries, and certain variable interest entities (“VIEs”) for which we are the primary beneficiary. All intercompany balances and transactions have been eliminated in consolidation. For consolidated entities where we own or are exposed to less than 100% of the economics, we record net income attributable to noncontrolling interest in our unaudited condensed consolidated statements of income equal to the percentage of the economic or ownership interest retained in such entities by the respective noncontrolling parties. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2022 filed with the Securities and Exchange Commission (“SEC”) on February 28, 2023, and as amended on March 20, 2023. Presentation Reclassification Amounts in equity and long-term investments and changes in fair value of equity and long-term investments, net, reported in the Company's comparative financial statements have been reclassified to conform to the current year presentation. These reclassifications had no net effect on the net income or net cash flows as previously reported. Factors Affecting Comparability Our historical financial condition and results of operations for the periods presented may not be comparable, either between periods or going forward due to the factors below and as discussed in Note 5, “Consolidated Entities and Acquisitions”. • Accounting consolidation of Entasis on February 17, 2022 and purchase of remaining noncontrolling interest in Entasis on July 11, 2022; • Sale of our 15% ownership interest in Theravance Respiratory Company, LLC (“TRC”) on July 20, 2022, and • Acquisition of La Jolla on August 22, 2022. Use of Management’s Estimates The preparation of unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the unaudited condensed consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. Management evaluates its significant accounting policies and estimates on an ongoing basis. We base our estimates on historical experience and other relevant assumptions that we believe to be reasonable under the circumstances. These estimates also form the basis for making judgments about the carrying values of assets and liabilities when these values are not readily apparent from other sources. Concentrations of Credit Risk and of Significant Suppliers and Partner Our financial instruments that are exposed to concentrations of credit risk consist primarily of cash and cash equivalents and equity and long-term investments. Although we deposit our cash with multiple financial institutions, our deposits, at times, may exceed federally insured limits. We are dependent on third-party manufacturers to supply active pharmaceutical ingredients (“API”) and drug products for research and development and commercial programs. These programs could be adversely affected by significant interruption in the supply of API or drug products. Currently, we derive most of our revenues from GSK and our near-term success depends in large part on GSK’s ability to successfully develop and commercialize the products in the respiratory programs partnered with GSK. Our near-term success depends in large part upon the performance by GSK of its commercial obligations under the GSK Agreements and the commercial success of RELVAR®/BREO® ELLIPTA® and ANORO® ELLIPTA®. If GSK does not devote sufficient resources to the commercialization or development of these products, is unsuccessful in its efforts, or chooses to reprioritize its commercial programs, our business would be materially harmed. GSK is responsible for all clinical and other product development, regulatory, manufacturing and commercialization activities for products developed under the GSK Agreements, including RELVAR®/BREO® ELLIPTA® and ANORO® ELLIPTA®. Our quarterly royalty revenues may fluctuate due to a variety of factors, many of which are outside of our control. Our royalty revenues under the GSK Agreements may not meet our analysts’ or investors’ expectations due to a number of important factors. We also started recognizing revenue from product sales as a result of our acquisition of La Jolla. Hospitals and other healthcare organizations generally purchase our products through a network of specialty distributors. These specialty distributors, which are located in the U.S., are considered our customers for accounting purposes. We do not believe that the loss of one of these distributors would significantly impact our ability to distribute our products, as we expect that sales volume would be absorbed by new or remaining distributors. Three of our customers each account for 32%, 31% and 30%, respectively, of our net product sales for the three months ended March 31, 2023. These same customers account for 38%, 23% and 36%, respectively, of our receivables from net product sales, which are included in “Accounts receivables, net” in our unaudited consolidated balance sheet as of March 31, 2023. Refer to Item 1A. “Risk Factors” disclosed in our Annual Report on Form 10-K for the year ended December 31, 2022. Segment Reporting We operate in a single segment, which is to provide capital return to stockholders by maximizing the potential value of our portfolio of royalties and innovative healthcare assets. Our Chief Operating Decision Maker (“CODM”) is our Chief Executive Officer. The CODM allocates resources and evaluates the performance of Innoviva at the consolidated level using information about our revenues, operating results and other key financial data as needed. Our revenues are generated primarily from our collaborative arrangements and royalty payments from GSK, located in Great Britain. Refer to Note 3, “Revenue Recognition”, for more information on our revenues for the periods presented. We also generate revenue from net sales of GIAPREZA® and XERAVA®. Our long-term assets are located within the United States. Variable Interest Entities The primary beneficiary of a variable interest entity (“VIE’) is required to consolidate the assets and liabilities of the VIE. When we obtain a variable interest in another entity, we assess at the inception of the relationship and upon occurrence of certain significant events whether the entity is a VIE and, if so, whether we are the primary beneficiary of the VIE based on our power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and our obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE. To assess whether we have the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance, we consider all the facts and circumstances, including our role in establishing the VIE and our ongoing rights and responsibilities. This assessment includes identifying the activities that most significantly impact the VIE’s economic performance and identifying which party, if any, has power over those activities. In general, the parties that make the most significant decisions affecting the VIE (management and representation on the Board of Directors) and have the right to unilaterally remove those decision-makers are deemed to have the power to direct the activities of a VIE. To assess whether we have the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE, we consider all of our economic interests that are deemed to be variable interests in the VIE. This assessment requires us to apply judgment in determining whether these interests, in the aggregate, are considered potentially significant to the VIE. Business Combination When we acquire an entity in a business combination, we recognize the fair value of all assets acquired, liabilities assumed, and any non-controlling interest in the acquiree and establish the acquisition date as the fair value measurement point. We recognize and measure goodwill as of the acquisition date, as the excess of the fair value of the consideration paid over the fair value of the identified net assets acquired. Acquisition-related expenses and related restructuring costs are expensed as incurred. Several valuation methods may be used to determine the fair value of assets acquired and liabilities assumed. For intangible assets, we typically use the income method. This method starts with a forecast of all of the expected future net cash flows for each asset. These cash flows are then adjusted to present value by applying an appropriate discount rate that reflects the risk factors associated with the cash flow streams. Some of the more significant estimates and assumptions inherent in the income method or other methods include the amount and timing of projected future cash flows, the discount rate selected to measure the risks inherent in the future cash flows and the assessment of the asset’s life cycle and the competitive trends impacting the asset, including consideration of any technical, legal, regulatory, or economic barriers to entry. Determining the useful life of an intangible asset also requires judgment as different types of intangible assets will have different useful lives and certain assets may even be considered to have indefinite useful lives. Cash and Cash Equivalents We consider all highly liquid investments purchased with a maturity of three months or less on the date of purchase to be cash equivalents. Cash equivalents are carried at cost, which approximates fair value. Accounts Receivable Accounts receivable are recorded net of estimates for prompt-pay discounts, chargebacks, returns and rebates. Allowances for prompt-pay discounts and chargebacks are based on contractual terms. We estimate the allowance for credit losses based on existing contractual payment terms, actual payment patterns of customers and individual customer circumstances. Inventory Inventory is stated at the lower of cost or estimated net realizable value on a first in, first out basis. We periodically analyze inventory levels and write down inventory as cost of products sold when the following occurs: inventory has become obsolete, inventory has a cost basis in excess of its estimated net realizable value, or inventory quantities are in excess of expected product sales. Goodwill and Intangible Assets Goodwill is recognized as the excess of the purchase consideration of an acquired entity over the fair value assigned to assets acquired and liabilities assumed in a business combination. Goodwill and intangible assets with an indefinite useful life are not amortized and are tested for impairment at least annually on the first day of December of each year or more frequently if indicators for potential impairment exist or whenever events or changes in circumstances indicate that the asset’s carrying asset amount may not be recoverable. Intangible assets with definite useful lives are amortized on a straight-line basis over their respective remaining useful lives and are tested for impairment only if indicators for potential impairment exist or whenever events or changes in circumstances indicate that the asset’s carrying amount may not be recoverable. Significant judgment may be involved in determining if an indicator of impairment has occurred. Operating Leases Right-of-use assets represent our right to use an underlying asset over the lease term and include any lease payments made prior to the lease commencement date and are reduced by lease incentives. Lease liabilities represent the present value of the total lease payments over the lease term, calculated using an estimated incremental borrowing rate. Lease expense is recognized on a straight-line basis over the expected lease term. Equity and Long-Term Investments We invest from time to time in equity and debt securities of private or public companies. If we determine that we have control over these companies under either voting or VIE models, we consolidate them in our unaudited condensed consolidated financial statements. If we determine that we do not have control over these companies under either voting or VIE models, we then determine if we have an ability to exercise significant influence via voting interests, board representation or other business relationships. We may account for the investments where we exercise significant influence using either an equity method of accounting or at fair value by electing the fair value option under Accounting Standards Codification (“ASC”) Topic 825, Financial Instruments. If the fair value option is applied to an investment that would otherwise be accounted for under the equity method, we apply it to all our financial interests in the same entity (equity and debt, including guarantees) that are eligible items. All gains and losses from fair value changes, unrealized and realized, are presented as changes in fair values of equity method investments, net, and changes in fair values of equity and long-term investments, net, within the unaudited condensed consolidated statements of income. If we conclude that we do not have an ability to exercise significant influence over an investee, we may elect to account for the security without a readily determinable fair value using the measurement alternative method under ASC 321, Investments - Equity Securities. This measurement alternative method allows us to measure the equity investment at its cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. We also invest in ISP Fund LP, which investments consist of money market funds, trading and equity and debt securities in the healthcare, pharmaceutical and biotechnology industries. Pursuant to the Partnership Agreement entered in December 2020, we became a limited partner of this partnership, and our contributions are subject to a 36-month lock-up period which restriction prevents us from having control and access to the contributions and related investments. These investments are classified as long-term investments in the unaudited condensed consolidated balance sheets. Revenue Recognition We apply the guidance on principal versus agent considerations under ASC Topic 606, Revenue from Contracts with Customers, to determine the appropriate treatment for the transactions between us and third parties. The classification of transactions under our arrangements is determined based on the nature and contractual terms of the arrangement along with the nature of the operations of the participants. Any consideration related to activities in which we are considered the principal, which includes being in control of the good or service before such good or service is transferred to the customer, are accounted for as product sales. Revenue is recognized when our customer obtains control of promised goods or services, in an amount that reflects the consideration which we expect to receive in exchange for those goods or services. Revenue is recognized through a five-step process: (i) identify the contract with the customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price for the contract; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue as a performance obligation is satisfied. Royalty Revenue We recognize the royalty revenue on net sales of products with respect to which we have contractual royalty rights in the period in which the royalties are earned. The net sales reports provided by our partner are based on its methodology and assumptions to estimate rebates and returns, which it monitors and adjusts regularly in light of contractual and legal obligations, historical trends, past experience and projected market conditions. Our partner may make significant adjustments to its sales based on actual results recorded, which could cause our royalty revenue to fluctuate. We conduct periodic royalty audits to evaluate the information provided by our partner. Royalties are recognized net of amortization of capitalized fees associated with any approval and launch milestone payments made to GSK. Revenue from Product Sales Revenue from product sales is recognized when our customers obtain control of the product and is recorded at the transaction price, net of estimates for variable consideration consisting of chargebacks, discounts, returns and rebates. Variable consideration is estimated using the expected-value amount method, which is the sum of probability-weighted amounts in a range of possible consideration amounts. Actual amounts of consideration ultimately received may differ from our estimates. If actual results vary materially from our estimates, we will adjust these estimates, which will affect revenue from product sales and earnings in the period such estimates are adjusted. These items may include: • Chargebacks: Chargebacks are discounts we provide to distributors in the event that the sales prices to end users are below the distributors’ acquisition price. This may occur due to a direct contract with a health system, a group purchasing organization (“GPO”) agreement or a sale to a government facility. Chargebacks are estimated based on known chargeback rates and recorded as a reduction of revenue on delivery to our customers. • Discounts: We offer customers various forms of incentives and consideration, including prompt-pay and other discounts. We estimate discounts primarily based on contractual terms. These discounts are recorded as a reduction of revenue on delivery to our customers. • Returns: We offer customers a limited right of return, generally for damaged or expired product. We estimate returns based on an internal analysis, which includes actual experience. The estimates for returns are recorded as a reduction of revenue on delivery to our customers. • Rebates: We participate in Medicaid rebate programs, which provide assistance to certain low-income patients based on each individual state’s guidelines regarding eligibility and services. Under the Medicaid rebate programs, we pay a rebate to each participating state, generally within three months after the quarter in which product was sold. Additionally, we may offer customer incentives and consideration in the form of volume-based or other rebates. The estimates for rebates are recorded as a reduction of revenue on delivery to our customers. We continue to assess our estimates of variable consideration as we accumulate additional historical data and will adjust these estimates accordingly. License Revenue At the inception of a licensing arrangement that includes development and regulatory milestone payments, we evaluate whether the milestones are considered probable of being achieved and estimate the amount to be included in the transaction price. We generally include these milestone payments in the transaction price when they are achieved because there is considerable uncertainty in the research and development processes that trigger receipt of these payments under our agreements. Similarly, we include approval milestone payments in the transaction price once the product is approved by the applicable regulatory agency. Research and Development Expenses Research and development expenses are recognized in the period that services are rendered or goods are received. Research and development expenses consist of salaries and benefits, laboratory supplies, facilities and other overhead costs, research-related manufacturing costs, contract service and clinical-related service costs performed by third party research organizations, research institutions and other outside service providers. Non-refundable prepayments for goods or services that will be used or rendered for future research and development activities are deferred and capitalized. Such amounts are recognized as an expense as the related goods are delivered or the related services are performed. We also utilize significant judgment and estimates to record accruals for estimated ongoing research costs based on the progress of the studies and progress of research manufacturing activities. Interest Expense on Deferred Royalty Obligation Interest expense related to the deferred royalty obligation is recognized over the expected repayment term of the deferred royalty obligation using the effective interest method. The assumptions used in determining the expected repayment term of the deferred royalty obligation require us to make estimates that could impact the effective interest rate. Each reporting period, we estimate the expected repayment term of the deferred royalty obligation based on forecasted net sales of GIAPREZA®. Changes in interest expense resulting from changes in the effective interest rate, if any, are recorded on a prospective basis. Refer to Note 11, “Debt” for more information.

Description of Operations and Summary of Significant Accounting Policies

1. Description of Operations and Summary of Significant Accounting Policies

Description of Operations

Innoviva, Inc. (and where context requires, together with its subsidiaries referred to as “Innoviva”, the “Company”, or “we” and other similar pronouns) is a company with a portfolio of royalties and innovative healthcare assets. Our royalty portfolio contains respiratory assets partnered with Glaxo Group Limited (“GSK”), including RELVAR®/BREO® ELLIPTA® (fluticasone furoate/vilanterol, “FF/VI”) and ANORO® ELLIPTA® (umeclidinium bromide/ vilanterol, “UMEC/VI”), and up until July 2022, TRELEGY® ELLIPTA® (the combination FF/UMEC/VI). We sold our 15% ownership interest in Theravance Respiratory Company, LLC (“TRC”) on July 20, 2022, and are no longer entitled to receive royalties on sales of TRELEGY® ELLIPTA® products. Under the Long-Acting Beta2 Agonist (“LABA”) Collaboration Agreement, Innoviva is entitled to receive royalties from GSK on sales of RELVAR®/BREO® ELLIPTA® as follows: 15% on the first $3.0 billion of annual global net sales and 5% for all annual global net sales above $3.0 billion; and royalties from the sales of ANORO® ELLIPTA®, which tier upward at a range from 6.5% to 10%.

We expanded our portfolio of royalties and innovative healthcare assets through the acquisition of Entasis Therapeutics Holdings Inc. (“Entasis”) on July 11, 2022 and the acquisition of La Jolla Pharmaceutical Company (“La Jolla”) on August 22, 2022. Our commercial and marketed products include GIAPREZA® (angiotensin II), approved to increase blood pressure in adults with septic or other distributive shock, and XERAVA® (eravacycline) for the treatment of complicated intra-abdominal infections in adults. Our development pipeline includes medicines for the treatment of bacterial infections, such as our lead asset sulbactam-durlobactam (“SUL-DUR”). As such, we have a wholly owned robust infectious disease and hospital operating platform, as well as other assets in these areas, such as a large equity stake in Armata Pharmaceuticals, a leader in bacteriophage development with potential use across a range of infectious and other serious diseases. We also have economic interests in other healthcare companies.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information. Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. The unaudited condensed consolidated financial statements have been prepared on the same basis as audited consolidated financial statements and, in our opinion, include all adjustments, consisting of all normal recurring adjustments, necessary for the fair presentation of our financial position, results of operations, comprehensive income and cash flows. The interim results are not necessarily indicative of the results of operations to be expected for the year ending December 31, 2023, or any other periods.

The accompanying unaudited condensed consolidated financial statements include the accounts of Innoviva, our wholly-owned subsidiaries, and certain variable interest entities (“VIEs”) for which we are the primary beneficiary. All intercompany balances and transactions have been eliminated in consolidation. For consolidated entities where we own or are exposed to less than 100% of the economics, we record net income attributable to noncontrolling interest in our unaudited condensed consolidated statements of income equal to the percentage of the economic or ownership interest retained in such entities by the respective noncontrolling parties. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2022 filed with the Securities and Exchange Commission (“SEC”) on February 28, 2023, and as amended on March 20, 2023.

Presentation Reclassification

Amounts in equity and long-term investments and changes in fair value of equity and long-term investments, net, reported in the Company's comparative financial statements have been reclassified to conform to the current year presentation. These reclassifications had no net effect on the net income or net cash flows as previously reported.

Factors Affecting Comparability

Our historical financial condition and results of operations for the periods presented may not be comparable, either between periods or going forward due to the factors below and as discussed in Note 5, “Consolidated Entities and Acquisitions”.

•

Accounting consolidation of Entasis on February 17, 2022 and purchase of remaining noncontrolling interest in Entasis on July 11, 2022;

•

Sale of our 15% ownership interest in Theravance Respiratory Company, LLC (“TRC”) on July 20, 2022, and

•

Acquisition of La Jolla on August 22, 2022.

Use of Management’s Estimates

The preparation of unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the unaudited condensed consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. Management evaluates its significant accounting policies and estimates on an ongoing basis. We base our estimates on historical experience and other relevant assumptions that we believe to be reasonable under the circumstances. These estimates also form the basis for making judgments about the carrying values of assets and liabilities when these values are not readily apparent from other sources.

Concentrations of Credit Risk and of Significant Suppliers and Partner

Our financial instruments that are exposed to concentrations of credit risk consist primarily of cash and cash equivalents and equity and long-term investments. Although we deposit our cash with multiple financial institutions, our deposits, at times, may exceed federally insured limits.

We are dependent on third-party manufacturers to supply active pharmaceutical ingredients (“API”) and drug products for research and development and commercial programs. These programs could be adversely affected by significant interruption in the supply of API or drug products.

Currently, we derive most of our revenues from GSK and our near-term success depends in large part on GSK’s ability to successfully develop and commercialize the products in the respiratory programs partnered with GSK. Our near-term success depends in large part upon the performance by GSK of its commercial obligations under the GSK Agreements and the commercial success of RELVAR®/BREO® ELLIPTA® and ANORO® ELLIPTA®. If GSK does not devote sufficient resources to the commercialization or development of these products, is unsuccessful in its efforts, or chooses to reprioritize its commercial programs, our business would be materially harmed. GSK is responsible for all clinical and other product development, regulatory, manufacturing and commercialization activities for products developed under the GSK Agreements, including RELVAR®/BREO® ELLIPTA® and ANORO® ELLIPTA®. Our quarterly royalty revenues may fluctuate due to a variety of factors, many of which are outside of our control. Our royalty revenues under the GSK Agreements may not meet our analysts’ or investors’ expectations due to a number of important factors.

We also started recognizing revenue from product sales as a result of our acquisition of La Jolla. Hospitals and other healthcare organizations generally purchase our products through a network of specialty distributors. These specialty distributors, which are located in the U.S., are considered our customers for accounting purposes. We do not believe that the loss of one of these distributors would significantly impact our ability to distribute our products, as we expect that sales volume would be absorbed by new or remaining distributors. Three of our customers each account for 32%, 31% and 30%, respectively, of our net product sales for the three months ended March 31, 2023. These same customers account for 38%, 23% and 36%, respectively, of our receivables from net product sales, which are included in “Accounts receivables, net” in our unaudited consolidated balance sheet as of March 31, 2023.

Refer to Item 1A. “Risk Factors” disclosed in our Annual Report on Form 10-K for the year ended December 31, 2022.

Segment Reporting

We operate in a single segment, which is to provide capital return to stockholders by maximizing the potential value of our portfolio of royalties and innovative healthcare assets. Our Chief Operating Decision Maker (“CODM”) is our Chief Executive Officer. The CODM allocates resources and evaluates the performance of Innoviva at the consolidated level using information about our revenues, operating results and other key financial data as needed. Our revenues are generated primarily from our collaborative arrangements and royalty payments from GSK, located in Great Britain. Refer to Note 3, “Revenue Recognition”, for more information on our revenues for the periods presented. We also generate revenue from net sales of GIAPREZA® and XERAVA®. Our long-term assets are located within the United States.

Variable Interest Entities

The primary beneficiary of a variable interest entity (“VIE’) is required to consolidate the assets and liabilities of the VIE. When we obtain a variable interest in another entity, we assess at the inception of the relationship and upon occurrence of certain significant events whether the entity is a VIE and, if so, whether we are the primary beneficiary of the VIE based on our power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and our obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE.

To assess whether we have the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance, we consider all the facts and circumstances, including our role in establishing the VIE and our ongoing rights and responsibilities. This assessment includes identifying the activities that most significantly impact the VIE’s economic performance and identifying which party, if any, has power over those activities. In general, the parties that make the most significant decisions affecting the VIE (management and representation on the Board of Directors) and have the right to unilaterally remove those decision-makers are deemed to have the power to direct the activities of a VIE.

To assess whether we have the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE, we consider all of our economic interests that are deemed to be variable interests in the VIE. This assessment requires us to apply judgment in determining whether these interests, in the aggregate, are considered potentially significant to the VIE.

Business Combination

When we acquire an entity in a business combination, we recognize the fair value of all assets acquired, liabilities assumed, and any non-controlling interest in the acquiree and establish the acquisition date as the fair value measurement point. We recognize and measure goodwill as of the acquisition date, as the excess of the fair value of the consideration paid over the fair value of the identified net assets acquired. Acquisition-related expenses and related restructuring costs are expensed as incurred.

Several valuation methods may be used to determine the fair value of assets acquired and liabilities assumed. For intangible assets, we typically use the income method. This method starts with a forecast of all of the expected future net cash flows for each asset. These cash flows are then adjusted to present value by applying an appropriate discount rate that reflects the risk factors associated with the cash flow streams. Some of the more significant estimates and assumptions inherent in the income method or other methods include the amount and timing of projected future cash flows, the discount rate selected to measure the risks inherent in the future cash flows and the assessment of the asset’s life cycle and the competitive trends impacting the asset, including consideration of any technical, legal, regulatory, or economic barriers to entry. Determining the useful life of an intangible asset also requires judgment as different types of intangible assets will have different useful lives and certain assets may even be considered to have indefinite useful lives.

Cash and Cash Equivalents

We consider all highly liquid investments purchased with a maturity of three months or less on the date of purchase to be cash equivalents. Cash equivalents are carried at cost, which approximates fair value.

Accounts Receivable

Accounts receivable are recorded net of estimates for prompt-pay discounts, chargebacks, returns and rebates. Allowances for prompt-pay discounts and chargebacks are based on contractual terms. We estimate the allowance for credit losses based on existing contractual payment terms, actual payment patterns of customers and individual customer circumstances.

Inventory

Inventory is stated at the lower of cost or estimated net realizable value on a first in, first out basis. We periodically analyze inventory levels and write down inventory as cost of products sold when the following occurs: inventory has become obsolete, inventory has a cost basis in excess of its estimated net realizable value, or inventory quantities are in excess of expected product sales.

Goodwill and Intangible Assets

Goodwill is recognized as the excess of the purchase consideration of an acquired entity over the fair value assigned to assets acquired and liabilities assumed in a business combination. Goodwill and intangible assets with an indefinite useful life are not amortized and are tested for impairment at least annually on the first day of December of each year or more frequently if indicators for potential impairment exist or whenever events or changes in circumstances indicate that the asset’s carrying asset amount may not be recoverable. Intangible assets with definite useful lives are amortized on a straight-line basis over their respective remaining useful lives and are tested for impairment only if indicators for potential impairment exist or whenever events or changes in circumstances indicate that the asset’s carrying amount may not be recoverable. Significant judgment may be involved in determining if an indicator of impairment has occurred.

Operating Leases

Right-of-use assets represent our right to use an underlying asset over the lease term and include any lease payments made prior to the lease commencement date and are reduced by lease incentives. Lease liabilities represent the present value of the total lease payments over the lease term, calculated using an estimated incremental borrowing rate. Lease expense is recognized on a straight-line basis over the expected lease term.

Equity and Long-Term Investments

We invest from time to time in equity and debt securities of private or public companies. If we determine that we have control over these companies under either voting or VIE models, we consolidate them in our unaudited condensed consolidated financial statements. If we determine that we do not have control over these companies under either voting or VIE models, we then determine if we have an ability to exercise significant influence via voting interests, board representation or other business relationships.

We may account for the investments where we exercise significant influence using either an equity method of accounting or at fair value by electing the fair value option under Accounting Standards Codification (“ASC”) Topic 825, Financial Instruments. If the fair value option is applied to an investment that would otherwise be accounted for under the equity method, we apply it to all our financial interests in the same entity (equity and debt, including guarantees) that are eligible items. All gains and losses from fair value changes, unrealized and realized, are presented as changes in fair values of equity method investments, net, and changes in fair values of equity and long-term investments, net, within the unaudited condensed consolidated statements of income.

If we conclude that we do not have an ability to exercise significant influence over an investee, we may elect to account for the security without a readily determinable fair value using the measurement alternative method under ASC 321, Investments - Equity Securities. This measurement alternative method allows us to measure the equity investment at its cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer.

We also invest in ISP Fund LP, which investments consist of money market funds, trading and equity and debt securities in the healthcare, pharmaceutical and biotechnology industries. Pursuant to the Partnership Agreement entered in December 2020, we became a limited partner of this partnership, and our contributions are subject to a 36-month lock-up period which restriction prevents us from having control and access to the contributions and related investments. These investments are classified as long-term investments in the unaudited condensed consolidated balance sheets.

Revenue Recognition

We apply the guidance on principal versus agent considerations under ASC Topic 606, Revenue from Contracts with Customers, to determine the appropriate treatment for the transactions between us and third parties. The classification of transactions under our arrangements is determined based on the nature and contractual terms of the arrangement along with the nature of the operations of the participants. Any consideration related to activities in which we are considered the principal, which includes being in control of the good or service before such good or service is transferred to the customer, are accounted for as product sales.

Revenue is recognized when our customer obtains control of promised goods or services, in an amount that reflects the consideration which we expect to receive in exchange for those goods or services. Revenue is recognized through a five-step process: (i) identify the contract with the customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price for the contract; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue as a performance obligation is satisfied.

Royalty Revenue

We recognize the royalty revenue on net sales of products with respect to which we have contractual royalty rights in the period in which the royalties are earned. The net sales reports provided by our partner are based on its methodology and assumptions to estimate rebates and returns, which it monitors and adjusts regularly in light of contractual and legal obligations, historical trends, past experience and projected market conditions. Our partner may make significant adjustments to its sales based on actual results recorded, which could cause our royalty revenue to fluctuate. We conduct periodic royalty audits to evaluate the information provided by our partner. Royalties are recognized net of amortization of capitalized fees associated with any approval and launch milestone payments made to GSK.

Revenue from Product Sales

Revenue from product sales is recognized when our customers obtain control of the product and is recorded at the transaction price, net of estimates for variable consideration consisting of chargebacks, discounts, returns and rebates. Variable consideration is estimated using the expected-value amount method, which is the sum of probability-weighted amounts in a range of possible consideration amounts. Actual amounts of consideration ultimately received may differ from our estimates. If actual results vary materially from our estimates, we will adjust these estimates, which will affect revenue from product sales and earnings in the period such estimates are adjusted. These items may include:

•

Chargebacks: Chargebacks are discounts we provide to distributors in the event that the sales prices to end users are below the distributors’ acquisition price. This may occur due to a direct contract with a health system, a group purchasing organization (“GPO”) agreement or a sale to a government facility. Chargebacks are estimated based on known chargeback rates and recorded as a reduction of revenue on delivery to our customers.

•

Discounts: We offer customers various forms of incentives and consideration, including prompt-pay and other discounts. We estimate discounts primarily based on contractual terms. These discounts are recorded as a reduction of revenue on delivery to our customers.

•

Returns: We offer customers a limited right of return, generally for damaged or expired product. We estimate returns based on an internal analysis, which includes actual experience. The estimates for returns are recorded as a reduction of revenue on delivery to our customers.

•

Rebates: We participate in Medicaid rebate programs, which provide assistance to certain low-income patients based on each individual state’s guidelines regarding eligibility and services. Under the Medicaid rebate programs, we pay a rebate to each participating state, generally within three months after the quarter in which product was sold. Additionally, we may offer customer incentives and consideration in the form of volume-based or other rebates. The estimates for rebates are recorded as a reduction of revenue on delivery to our customers.

We continue to assess our estimates of variable consideration as we accumulate additional historical data and will adjust these estimates accordingly.

License Revenue

At the inception of a licensing arrangement that includes development and regulatory milestone payments, we evaluate whether the milestones are considered probable of being achieved and estimate the amount to be included in the transaction price. We generally include these milestone payments in the transaction price when they are achieved because there is considerable uncertainty in the research and development processes that trigger receipt of these payments under our agreements. Similarly, we include approval milestone payments in the transaction price once the product is approved by the applicable regulatory agency.

Research and Development Expenses

Research and development expenses are recognized in the period that services are rendered or goods are received. Research and development expenses consist of salaries and benefits, laboratory supplies, facilities and other overhead costs, research-related manufacturing costs, contract service and clinical-related service costs performed by third party research organizations, research institutions and other outside service providers. Non-refundable prepayments for goods or services that will be used or rendered for future research and development activities are deferred and capitalized. Such amounts are recognized as an expense as the related goods are delivered or the related services are performed. We also utilize significant judgment and estimates to record accruals for estimated ongoing research costs based on the progress of the studies and progress of research manufacturing activities.

Interest Expense on Deferred Royalty Obligation

Interest expense related to the deferred royalty obligation is recognized over the expected repayment term of the deferred royalty obligation using the effective interest method. The assumptions used in determining the expected repayment term of the deferred royalty obligation require us to make estimates that could impact the effective interest rate. Each reporting period, we estimate the expected repayment term of the deferred royalty obligation based on forecasted net sales of GIAPREZA®. Changes in interest expense resulting from changes in the effective interest rate, if any, are recorded on a prospective basis. Refer to Note 11, “Debt” for more information.
