NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. Description of Operations and Summary of Significant Accounting Policies

Description of Operations

Innoviva Inc. (referred to as “Innoviva”, the “Company”, or “we” and other similar pronouns) is a company with a portfolio of royalties and other healthcare assets. Our royalty portfolio contains respiratory assets partnered with Glaxo Group Limited (“GSK”), including RELVAR®/BREO® ELLIPTA® (fluticasone furoate/ vilanterol, “FF/VI”), ANORO® ELLIPTA® (umeclidinium bromide/ vilanterol, “UMEC/VI”) and TRELEGY® ELLIPTA® (the combination FF/UMEC/VI). 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%. Innoviva is also entitled to 15% of royalty payments made by GSK under its agreements originally entered into with us, and since assigned to Theravance Respiratory Company, LLC (“TRC”), including TRELEGY® ELLIPTA® and any other product or combination of products that may be discovered or developed in the future under the LABA Collaboration Agreement and the Strategic Alliance Agreement with GSK (referred to herein as the “GSK Agreements”), which have been assigned to TRC other than RELVAR®/BREO® ELLIPTA® and ANORO® ELLIPTA®.

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) for interim financial information. Accordingly, they do not include all of the information and notes required by US GAAP for complete financial statements. In our opinion, the unaudited consolidated financial statements have been prepared on the same basis as audited consolidated financial statements and include all adjustments, consisting of only 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, 2021 or any other period.

The accompanying unaudited consolidated financial statements include the accounts of Innoviva, our wholly-owned subsidiaries and certain variable interest entities 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 (loss) attributable to noncontrolling interest in our unaudited 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 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, 2020 filed with the Securities and Exchange Commission (“SEC”) on February 25, 2021 (“2020 Form 10-K”).

Variable Interest Entities

We evaluate our ownership, contractual and other interest in entities to determine if they are variable interest entities (“VIE”). We evaluate whether we have a variable interest in those entities and the nature and extent of those interests. Based on our evaluation, if we determine we are the primary beneficiary of a VIE, we consolidate the entity in our financial statements.

Equity Investments

We invest from time to time in equity securities of private or public companies. If we determine that we have control over these companies under either voting or VIE models, we include them in our 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.

9

We may account for the equity 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 and long-term investments, net on the 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 an equity security without a readily determinable fair value using the measurement alternative described in ASC Topic 825. This measurement alternative 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.

Revenue Recognition

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.

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 have the ability to 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.

Accounting Pronouncement Adopted by the Company

In December 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes”, which is intended to simplify various aspects related to accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2020, with early adoption permitted. We adopted ASU 2019-12 effective January 1, 2021. The adoption did not have a material impact on our consolidated financial statements.

In October 2020, the FASB issued ASU 2020-10, Codification Improvements. This ASU improves the codification by ensuring that all guidance that requires or provides an option for an entity to provide information in the notes to financial statements is codified in the disclosure section of the codification. The ASU also clarifies various topics in the codification so that entities can apply guidance more consistently. The ASU is effective for fiscal years beginning after December 15, 2020. We adopted ASU 2020-10 effective January 1, 2021. The adoption did not have a material impact on our consolidated financial statements.

Recently Issued Accounting Standards or Updates Not Yet Adopted

In August 2020, the FASB issued ASU 2020-06, Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which is intended to simplify the accounting for convertible instruments by removing certain separation models in Subtopic 470-20 for convertible instruments. The ASU is effective for fiscal years beginning after December 15, 2021, and for interim periods within those fiscal years with early adoption permitted. We are currently in the process of evaluating the effects of the provisions of ASU 2020-06 on our consolidated financial statements. 

2. Net Income Per Share

Basic net income per share attributable to Innoviva stockholders is computed by dividing net income attributable to Innoviva stockholders by the weighted-average number of shares of common stock outstanding. Diluted net income per share attributable to Innoviva stockholders is computed by dividing net income attributable to Innoviva stockholders by the weighted-average number of

10

shares of common stock and dilutive potential common stock equivalents then outstanding. Dilutive potential common stock equivalents include the assumed exercise, vesting and issuance of employee stock awards using the treasury stock method, as well as common stock issuable upon assumed conversion of our convertible subordinated notes due 2023 (the “2023 Notes”) using the if converted method.

Our convertible senior notes due 2025 (the “2025 Notes”) are convertible, based on the applicable conversion rate, into cash, shares of our common stock or a combination thereof, at our election. Our current intent is to settle the principal amount of the 2025 Notes in cash upon conversion. The impact of the assumed conversion premium to diluted net income per share is computed using the treasury stock method. As the average market price per share of our common stock as reported on The Nasdaq Global Select Market was lower than the initial conversion price of $17.26 per share, there was no dilutive effect of the assumed conversion premium for the three and nine months ended September 30, 2021 and 2020, respectively.

The following table shows the computation of basic and diluted net income per share for the three and nine months ended September 30, 2021 and 2020:

We also consolidate the financial results of ISP Fund LP (the “Partnership”), which is our partnership with Sarissa Capital Management LP (“Sarissa Capital”), as we have determined that the Partnership is a VIE and we are its primary beneficiary.

Theravance Respiratory Company, LLC

The primary source of revenue for TRC is the royalties generated from the net sales of TRELEGY® ELLIPTA® by GSK. As of September 30, 2021, TRC held equity investments in InCarda Therapeutics, Inc.

In May 2021, Strategic Partners received a distribution of $110.0 million from the Partnership to provide funding to Innoviva for a strategic repurchase of shares held by GSK. Pursuant to the letter agreement entered into between Strategic Partners, the Partnership and Sarissa Capital Fund GP LP on May 20, 2021, Strategic Partners is obligated to make additional capital contributions to the Partnership in an aggregate amount equal to the amount of the distribution ($110.0 million) prior to March 31, 2022.

5. Financial Instruments and Fair Value Measurements

Equity Investment in Armata

During the first quarter of 2020, Innoviva acquired 8,710,800 shares of common stock and an equal number of warrants of Armata Pharmaceuticals, Inc. (“Armata”) for $25.0 million in cash. Armata is a clinical stage biotechnology company focused on precisely targeted bacteriophage therapeutics for antibiotic-resistant infections.

On January 26, 2021, Innoviva Strategic Opportunities LLC (“ISO”), our wholly owned subsidiary, entered into a securities purchase agreement with Armata to acquire 6,153,847 shares of Armata common stock and warrants to purchase 6,153,847 additional shares of Armata common stock for approximately $20.0 million. The investment was closed in two tranches on January 26, 2021 and March 17, 2021. The investments support Armata’s ongoing advancement of its bacteriophage development programs. The additional investment in the first quarter of 2021 increased Innoviva and ISO’s combined ownership to 59.6% as of March 31, 2021. Armata entered into a voting agreement with the Company and ISO, pursuant to which the Company and ISO agreed not to vote or take any action by written consent with respect to any common shares held by the Company and ISO that represent, in the aggregate, more than 49.5% of the total number of shares of Armata’s common stock issued and outstanding as of the record date for voting on the matters related to election or removal of Armata’s board members. As of September 30, 2021, three of the eight members of Armata’s board of directors are also members of the board of directors of Innoviva. As of September 30, 2021 and December 31, 2020, we owned approximately 59.5% and 46.6%, respectively, of Armata’s common stock.

The investment in Armata provides Innoviva and ISO the ability to have significant influence, but not control over Armata’s operations. Based on our evaluation, we determined that Armata is a VIE, but Innoviva and ISO are not the primary beneficiary of the VIE. We continue to elect the fair value option to account for both Armata’s common stock and warrants. The fair value of Armata’s common stock is measured based on its closing market price. The warrants purchased in 2020 and 2021 have an exercise price of $2.87 and $3.25 per share, respectively. All warrants are exercisable immediately within five years from the issuance date of the warrants and include a cashless exercise option. We use the Black-Scholes-Merton pricing model to estimate the fair value of these warrants with the following input assumptions: Armata’s closing market price on the valuation date, the risk-free interest rate computed based on the U.S. Treasury yield, the remaining contractual term as the expected term, and the expected stock price volatility calculated based on the historical volatility of the common stock of Armata and its peer companies.

As of September 30, 2021, the fair values of Armata’s common stock and warrants were estimated at $53.8 million and $35.5 million, respectively. As of December 31, 2020, the fair values of Armata’s common stock and warrants were estimated at $26.0 million and $18.0 million, respectively. The total fair value of both financial instruments in the amount of $89.3 million and $44.0 million was recorded as equity and long-term investments on the consolidated balance sheets as of September 30, 2021 and December 31, 2020, respectively. During the three and nine months ended September 30, 2021, we recorded $11.6 million unrealized loss and $25.3 million unrealized gains, respectively, as changes in fair values of equity and long-term investments, net on the consolidated statements of income. During the three and nine months ended September 30, 2020, we recorded $12.4 million unrealized loss and $23.0 million unrealized gains, respectively, as changes in fair values of equity and long-term investments, net on the consolidated statements of income.

Equity Investment in Entasis

During the second quarter of 2020, we purchased 14,000,000 shares of common stock as well as warrants to purchase 14,000,000 additional shares of common stock of Entasis Therapeutics, Inc. (“Entasis”) for approximately $35.0 million in cash. Entasis is a clinical-stage biotechnology company focused on the discovery and development of novel antibacterial products.

During the third quarter of 2020, we purchased 4,672,897 shares of Entasis common stock as well as warrants to purchase 4,672,897 additional shares of its common stock for approximately $12.5 million in cash. Innoviva has a right to designate two members to Entasis’ board. As of September 30, 2021, no Innoviva designees are serving on Entasis’ six-member board.

On May 3, 2021, ISO entered into a securities purchase agreement with Entasis to acquire 10,000,000 shares of Entasis common stock and warrants to purchase 10,000,000 additional shares of Entasis common stock for approximately $20.0 million. The investment was closed in two tranches on May 3, 2021 and June 11, 2021. This investment supports the continued development of Entasis’ novel pipeline of pathogen-targeted antibacterial product candidates. As of September 30, 2021, we owned approximately 60.6% of Entasis’ common stock. As of December 31, 2020, we owned approximately 51.0% of Entasis’ common stock.

14

The investment in Entasis provides Innoviva the ability to have significant influence, but not control over Entasis’ operations. Based on our evaluation, we determined that Entasis is a VIE, but Innoviva is not the primary beneficiary of the VIE. We elected the fair value option to account for both Entasis’s common stock and warrants at fair value. The fair value of Entasis’ common stock is measured based on its closing market price at each balance sheet date. The warrants have an exercise price of $2.50 per share and $2.675 per share for those warrants acquired in the second and third quarter of 2020, respectively. The warrants acquired in the second quarter of 2021 have an exercise price of $2.00 per share. All of the warrants are exercisable immediately within five years from the issuance date of the warrants and include a cashless exercise option. We use the Black-Scholes-Merton pricing model to estimate the fair value of these warrants.

As of September 30, 2021, the fair values of Entasis’s common stock and warrants were estimated at $95.8 million and $70.4 million, respectively. As of December 31, 2020, the fair values of Entasis’s common stock and warrants were estimated at $46.1 million and $31.9 million, respectively. The total fair value of both financial instruments in the amount of $166.2 million and $78.0 million was recorded as equity and long-term investments on the consolidated balance sheets as of September 30, 2021 and December 31, 2020, respectively. During the three and nine months ended September 30, 2021, we recorded $34.9 million and $68.1 million unrealized gains as changes in fair values of equity and long-term investments, net on the consolidated statements of income. During the three and nine months ended September 30, 2020, we recorded $17.0 million unrealized loss and $16.3 million unrealized gain, respectively, as changes in fair values of equity and long-term investments, net on the consolidated statements of income.

Equity Investment in InCarda

During the third quarter of 2020, TRC purchased 20,469,432 shares of Series C preferred stock and warrants to purchase 5,117,358 additional shares of Series C preferred stock of InCarda Therapeutics, Inc. (“InCarda”) for $15.0 million. $0.8 million was incurred for investment due diligence costs and recorded as part of the equity investment on the consolidated balance sheets. InCarda is a privately held biopharmaceutical company focused on developing inhaled therapies for cardiovascular diseases. As of September 30, 2021, one of InCarda’s eight board members is designated by TRC. As of September 30, 2021 and December 31, 2020, TRC held 13.0% and 13.4%, respectively, of InCarda’s outstanding equity.

The investment in InCarda does not provide TRC the ability to control or have significant influence over InCarda’s operations. Based on our evaluation, we determined that InCarda is a VIE, but TRC is not the primary beneficiary of the VIE. We account for our investment in the Series C preferred shares in InCarda using the measurement alternative. Under the measurement alternative, the equity investment is initially recorded at its allocated cost, but the carrying value may be adjusted through earnings upon an impairment or when there is an observable price change involving the same or a similar investment with the same issuer. As of September 30, 2021 and December 31, 2020, we recorded $15.8 million from our investment in InCarda’s Series C preferred stock as equity and long-term investments on the consolidated balance sheets. There was no impairment or other change to the value of InCarda’s Series C preferred stock as of September 30, 2021 and December 31, 2020.

The warrants are recorded at fair value and subject to remeasurement at each balance sheet date. The warrants are exercisable immediately with an exercise price of $0.7328 per share. In September 2021, TRC and InCarda entered into an amendment to extend the expiration date of the warrants from October 6, 2021 to March 31, 2022. We use the Black-Scholes-Merton pricing model to estimate the fair value of the warrants with the following input assumptions: the exercise price of the warrants, the risk-free interest rate computed based on the U.S. Treasury yield, the remaining contractual term as the expected term, and the expected stock price volatility calculated based on the historical volatility of the common stock of its peer companies. As of September 30, 2021 and December 31, 2020, the fair value of InCarda’s warrants was estimated at $0.6 million and $1.1 million, respectively, and recorded as equity and long-term investments on the consolidated balance sheets. During the three and nine months ended September 30, 2021, we recorded $0.1 million unrealized gain and $0.6 million unrealized loss, respectively, as changes in fair values of equity and long-term investments, net on the consolidated statements of income.

Equity Investment in ImaginAb

On March 18, 2021, TRC entered into a securities purchase agreement with ImaginAb, Inc. to purchase 4,051,724 shares of ImaginAb Series C preferred stock for $4.7 million. On the same day, TRC also entered into a securities purchase agreement with one of ImaginAb’s common stockholders to purchase 4,097,157 shares of ImaginAb common stock for $1.3 million. ImaginAb is a privately held biotechnology company focused on clinically managing cancer and autoimmune diseases via molecular imaging. $0.4 million was incurred for investment due diligence costs and execution and recorded as part of the equity investment on the consolidated balance sheets. As of September 30, 2021, one of ImaginAb’s five board members is designated by TRC. As of September 30, 2021, TRC held 12.5% of ImaginAb equity ownership.

15

The investment in ImaginAb does not provide TRC the ability to control or have significant influence over ImaginAb’s operations. Based on our evaluation, we determined that ImaginAb is a VIE, but TRC is not the primary beneficiary of the VIE. Because ImaginAb’s equity securities are not publicly traded and do not have a readily determinable fair value, we have accounted for our investment in ImaginAb’s Series C preferred stock and common stock using the measurement alternative. Under the measurement alternative, the equity investment is initially recorded at its allocated cost, but the carrying value may be adjusted through earnings upon an impairment or when there is an observable price change involving the same or a similar investment with the same issuer. As of September 30, 2021, $6.4 million was recorded as equity and long-term investments on the consolidated balance sheets. There was no change to the value of our investment in ImaginAB’s equity securities as of September 30, 2021.

Convertible Senior Notes Due 2025

In accordance with accounting guidance for debt with conversion and other options, we separately account for the liability and equity components of the 2025 Notes by allocating the proceeds between the liability component and the embedded conversion option (“equity component”) due to our ability to settle the conversion obligation of the 2025 Notes in cash, common stock or a combination of cash and common stock, at our option. The carrying amount of the liability component was calculated by measuring the fair value of a similar liability that does not have an associated convertible feature using the income approach. The allocation was performed in a manner that reflected our non-convertible debt borrowing rate for similar debt. The equity component of the 2025 Notes was recognized as a debt discount and represents the difference between the proceeds from the issuance of the 2025 Notes and the fair value of the liability of the 2025 Notes on the date of issuance. The excess of the principal amount of the liability component over its carrying amount (“debt discount”) is amortized to interest expense using the effective interest method over the term of the 2025 Notes. The equity component is not remeasured as long as it continues to meet the conditions for equity classification.

Legal Proceedings

From time to time, the Company is involved in legal proceedings in the ordinary course of its business. Currently, we believe that no litigation or arbitration, either individually or in the aggregate, to which we are presently a party is likely to have a material adverse effect on our operating results or financial position.

9. Shareholders’ Equity

On May 20, 2021, the Company entered into a share repurchase agreement with GSK to buy back 32,005,260 shares of its common stock at $12.25 per share from GSK, representing all of the shares of common stock or other capital interests of Innoviva owned by GSK or its affiliates. The total consideration including related transaction fees was $394.1 million. The share repurchase closed on May 25, 2021, and the shares were transferred to the Company. These shares are recorded as treasury stock on the consolidated balance sheets.

10. Income Taxes

Provisional income tax expense for the three and nine months ended September 30, 2021 was $20.5 million and $65.6 million, respectively, compared to $8.9 million and $44.7 million for the same periods in 2020 respectively. The Company’s effective income tax rate for the nine months ended September 30, 2021 was 16.9%, compared to 17.0% for the same period in 2020. The income tax expense for the nine months ended September 30, 2021 and 2020 was determined based upon estimates of the Company’s effective income tax rates in various jurisdictions. Our effective income tax rate for the nine months ended September 30, 2021 was lower than the U.S. federal statutory income tax rate due primarily to non-deductible expenses, noncontrolling interest and state income taxes.

OVERVIEW

Executive Summary

Innoviva, Inc. (“Innoviva”, the “Company”, the “Registrant” or “we” and other similar pronouns) is a company with a portfolio of royalties and other healthcare assets. Our royalty portfolio contains respiratory assets partnered with Glaxo Group Limited (“GSK”), including RELVAR®/BREO® ELLIPTA® (fluticasone furoate/ vilanterol, “FF/VI”), ANORO® ELLIPTA® (umeclidinium bromide/ vilanterol, “UMEC/VI”) and TRELEGY® ELLIPTA® (the combination FF/UMEC/VI). 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%. Innoviva is also entitled to 15% of royalty payments made by GSK under its agreements originally entered into with us, and since assigned to Theravance Respiratory Company, LLC (“TRC”), including TRELEGY® ELLIPTA® and any other product or combination of products that may be discovered or developed in the future under the LABA Collaboration Agreement and the Strategic Alliance Agreement with GSK (referred to herein as the “GSK Agreements”), which have been assigned to TRC other than RELVAR®/BREO® ELLIPTA® and ANORO® ELLIPTA®.

Our company structure and organization are tailored to our focused activities of managing our respiratory assets partnered with GSK, optimizing our operations and augmenting capital allocation. Our revenues consist of royalties from our respiratory partnership agreements with GSK.

Collaborative Arrangements with GSK

LABA Collaboration

In November 2002, we entered into the LABA collaboration with GSK to develop and commercialize once-daily LABA products for the treatment of chronic obstructive pulmonary disorder (“COPD”) and asthma (the “LABA Collaboration Agreement”). For the treatment of COPD, the collaboration has developed three combination products:

RELVAR®/BREO® ELLIPTA® (“FF/VI”) (BREO® ELLIPTA® is the proprietary name in the U.S. and Canada and RELVAR® ELLIPTA® is the proprietary name outside the U.S. and Canada), a once-daily combination medicine consisting of a LABA, vilanterol (VI), and an inhaled corticosteroid (“ICS”), fluticasone furoate (“FF”),

ANORO® ELLIPTA® (“UMEC/VI”), a once-daily medicine combining a long-acting muscarinic antagonist (“LAMA”), umeclidinium bromide (“UMEC”), with a LABA, vilanterol (VI), and

TRELEGY® ELLIPTA® (the combination FF/UMEC/VI), a once-daily combination medicine consisting of an ICS, LAMA and LABA.

22

As a result of the launch and approval of RELVAR®/BREO® ELLIPTA® and ANORO® ELLIPTA® in the U.S., Japan and Europe, in accordance with the LABA Collaboration Agreement, we paid milestone fees to GSK totaling $220.0 million during the year ended December 31, 2014. The milestone fees paid to GSK were recognized as capitalized fees paid to a related party, which are being amortized over their estimated useful lives commencing upon the commercial launch of the products.

Critical Accounting Policies and Estimates

Our management’s discussion and analysis of our financial condition and results of operations is based on our financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”). The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the financial statements, as well as the reported revenue generated and expenses incurred during the reporting periods. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

As part of our capital allocation strategies, we invest from time to time in equity securities of private or public companies. We also enter into strategic partnerships in order to accelerate the execution of our strategy and enhance returns on our capital. If we determine that we have control over these companies or partnerships, we consolidate the financial statements of these companies or partnerships. If we determine that we do not have control over these companies or partnerships 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 equity 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 and long-term investments, net on the 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 an equity security without a readily determinable fair value using the measurement alternative as prescribed by ASC Topic 825. This measurement alternative 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 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 have the ability to 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.

There were no significant changes to our critical accounting policies and estimates. Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in Part II, Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2020 filed with the SEC on February 25, 2021 provides a more complete discussion of our critical accounting policies and estimates.

Total net revenue increased to $97.9 million and $284.2 million for the three and nine months ended September 30, 2021, compared to $88.7 million and $246.3 million, respectively, for the same periods a year ago, primarily due to favorable adjustments and the growth in prescriptions for our respiratory products.

Research & Development

Research and development (“R&D”) expenses attributable to Pulmoquine’s product development efforts were $0.4 million and $0.5 million for the three and nine months ended September 30, 2021. Research and development expenses of $1.0 million and $1.6 million for the three and nine months ended September 30, 2020 were attributable to Pulmoquine’s product development efforts.

General & Administrative

General and administrative expenses, as compared to the prior year periods, were as follows:

	Three Months Ended September 30,				Change						Nine Months Ended September 30,				Change

General and administrative expenses for the three months ended September 30, 2021 decreased compared to the same periods in 2020. General and administrative expenses for the nine months ended September 30, 2021 increased compared to the same periods in 2020 mainly due to business development related advisory service fees and legal expenses incurred for the arbitration initiated by Theravance Biopharma against the Company and TRC. The arbitration related legal fees were recognized in TRC’s statement of income.

Other Income, net and Interest Income

Other income, net and interest income, as compared to the prior year periods, were as follows:

The increase in other expense, net, for the three and nine months ended September 30, 2021 compared to the same periods a year ago was primarily due to the expenses incurred by ISP Fund LP. Interest income increased for the three and nine months ended September 30, 2021 compared to the same periods a year ago mainly due to favorable returns on investments managed by the ISP Fund LP.

Interest Expense

Interest expense, as compared to the prior year periods, was as follows:

	Three Months Ended September 30,				Change					Nine Months Ended September 30,				Change
(In thousands)	2021		2020		$		%			2021		2020		$		%
Interest expense	$	4,790	$	4,603	$	187		4	%	$	14,229	$	13,680	$	549		4	%

Interest expense includes the amortization of debt discount and issuance costs for our convertible notes. The increase in interest expense was mainly due to more debt discount and issuance costs being recognized through amortization.

Changes in Fair Values of Equity and Long-Term Investments

Changes in fair values of equity and long-term investments, as compared to the prior year periods, were as follows:

	Three Months Ended September 30,					Change			Nine Months Ended September 30,				Change
(In thousands)	2021		2020			$		%	2021		2020		$		%

Provision for Income Taxes

The provisional income tax expense for the three and nine months ended September 30, 2021 was $20.5 million and $65.6 million with an effective income tax rate of 16.9%, respectively, compared to $8.9 million and $44.7 million, respectively, with an effective income tax rate of 17.0% in the same period a year ago.

Net Income Attributable to Noncontrolling Interest

Net income attributable to noncontrolling interest, as compared to the prior periods, was as follows:

	Three Months Ended September 30,				Change			Nine Months Ended September 30,				Change
(In thousands)	2021		2020		$		%	2021		2020		$		%
Net income attributable to    noncontrolling interest	$	30,208	$	13,403	$	16,805	*	$	67,678	$	48,299	$	19,379		40	%

*Not Meaningful

This represents the 85% share of net income in Theravance Respiratory Company, LLC for Theravance Biopharma for the three and nine months ended September 30, 2021 and 2020. The increase was primarily due to the increase in the growth in prescriptions and market share for TRELEGY® ELLIPTA®.

Liquidity and Capital Resources

Liquidity

Since our inception, we have financed our operations primarily through private placements and public offerings of equity and debt securities and payments received under collaborative arrangements. For the nine months ended September 30, 2021, we

25

generated gross royalty revenues from GSK of $294.6 million. Net cash and cash equivalents totaled $135.1 million and receivables from GSK totaled $101.3 million as of September 30, 2021.

Adequacy of Cash Resources to Meet Future Needs

We believe that cash from projected future royalty revenues and our cash, cash equivalents and marketable securities will be sufficient to meet our anticipated debt service and operating needs for at least the next 12 months based upon current operating plans and financial forecasts. If our current operating plans and financial forecasts change, we may require additional funding sooner in the form of public or private equity offerings or debt financings. Furthermore, if in our view favorable financing opportunities arise, we may seek additional funding at any time. However, future financing may not be available in amounts or on terms acceptable to us, if at all. This could leave us without adequate financial resources to fund our operations as currently planned. In addition, from time to time we may restructure or reduce our debt, including through tender offers, redemptions, amendments, repurchases or otherwise, all allowable with the terms of our debt agreements.

Cash Flows

Cash flows, as compared to the prior year period, were as follows:

	Nine Months Ended September 30,
(In thousands)	2021			2020			Change
Net cash provided by operating activities	$	265,432		$	227,833		$	37,599

Net cash used in financing activities		(440,431	)		(27,280	)		(413,151	)

Cash Flows from Operating Activities

Net cash provided by operating activities for the nine months ended September 30, 2021 was $265.4 million, consisting primarily of our net income of $323.2 million, adjusted for net non-cash items such as $65.6 million of deferred income taxes, $10.4 million of depreciation and amortization, and $6.8 million of amortization of debt discount and issuance costs, partially offset by an increase of $132.5 million in the fair value of our equity and long-term investments, net and an increase in receivables from collaborative arrangements of $7.3 million.

Net cash provided by operating activities for the nine months ended September 30, 2020 was $227.8 million, consisting primarily of our net income of $218.8 million, adjusted for net non-cash items such as $44.7 million of deferred income taxes, $10.4 million of depreciation and amortization, partially offset by an increase of $39.2 million in the fair value of our equity investments and an increase of $12.7 million in receivables from collaborative arrangements.

Cash Flows from Investing Activities

Net cash provided by investing activities for the nine months ended September 30, 2021 of $63.6 million was primarily due to $110.0 million in distribution of equity and long-term investments from the ISP Fund LP, partially offset by $46.4 million investments in Armata, ImaginAb and Entasis.

Net cash provided by investing activities for the nine months ended September 30, 2020 of $0.5 million was primarily due to $86.0 million received from maturities of marketable securities, partially offset by $12.9 million in purchases of marketable securities and $72.5 million for our investments in Armata and Entasis.

Cash Flows from Financing Activities

Net cash used in financing activities for the nine months ended September 30, 2021 of $440.4 million was primarily due to $394.1 million used for our common stock repurchase from GSK and $46.4 million distributions to noncontrolling interest.

Net cash used in financing activities for the nine months ended September 30, 2020 of $27.3 million was primarily due to $28.0 million distributions to noncontrolling interest.

Item 3. Quantitative and Qualitative Disclosure about Market Risk

There have been no significant changes in our market risk or how our market risk is managed compared to those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2020.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures.

We conducted an evaluation as of September 30, 2021, under the supervision and with the participation of our management, of the effectiveness of the design and operation of our disclosure controls and procedures, which are defined under SEC rules as controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files under the Securities Exchange Act of 1934 (“Exchange Act”) is recorded, processed, summarized and reported within required time periods. Based upon that evaluation, our Chief Executive Officer and Chief Accounting Officer, concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance levels.

Limitations on the Effectiveness of Controls

Our management does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent all errors and all frauds. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefit of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within Innoviva have been detected. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Changes in Internal Control over Financial Reporting

There have been no material changes in our internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) during the quarter ended September 30, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

In May 2019, Theravance Biopharma, which is the owner of 85% of the economic interests in TRC, initiated arbitration against the Company and TRC, relating to a dispute as to the determination by Innoviva (as manager of TRC) to cause TRC to explore potential reinvestment opportunities for the royalty proceeds received by GSK into initiatives that Innoviva believes will increase the value of TRC and TRELEGY® ELLIPTA®. Theravance Biopharma alleged that, in causing TRC to not distribute substantially all royalty proceeds received from GSK, Innoviva breached the limited liability company operating agreement governing TRC (the “Operating Agreement”), as well as the fiduciary duties applicable to Innoviva as manager of TRC. The hearing in respect of the arbitration was conducted from July 23, 2019 through July 25, 2019. Post-arbitration oral argument was heard on August 14, 2019. On September 26, 2019, the arbitrator issued a final decision. The arbitrator ruled that Innoviva did not breach the Operating Agreement or its fiduciary duties by withholding royalties or pursuing reinvestment opportunities. Accordingly, the Company is permitted to continue to pursue development and commercialization initiatives. The arbitrator did conclude that Innoviva breached a provision of the Operating Agreement requiring Innoviva to deliver quarterly financial plans to Theravance Biopharma. However, the arbitrator concluded that this technical breach did not cause any damages to Theravance Biopharma and the arbitrator awarded limited injunctive relief to expand and clarify the disclosure obligations under the Operating Agreement related to the delivery of financial plans and the pursuit of investment opportunities (if those opportunities related to TRELEGY® ELLIPTA®). Finally, the arbitrator ruled that the Company is entitled to indemnification from TRC for 95% of its fees and expenses incurred in connection with the arbitration.

On September 30, 2019, the Company and TRC filed a Verified Complaint in the Court of Chancery of the State of Delaware (“Court of Chancery”) to confirm the arbitration award. The award was confirmed by the Court of Chancery on May 4, 2020.

On July 16, 2020, Innoviva and TRC initiated a lawsuit in the Court of Chancery against Theravance Biopharma, seeking a permanent injunction preventing Theravance Biopharma from interfering with Innoviva’s ability to cause TRC to reserve cash to pursue non-Trelegy related investments opportunities and a declaration that the arbitration award conclusively established that Innoviva, as manager of TRC, has such authority. The Court of Chancery directed the parties to obtain the arbitrator’s opinion as to whether the arbitration award addressed non-Trelegy related investment opportunities. On July 31, 2020, the arbitrator, while reiterating that Innoviva has broad authority as manager of TRC, found that this award did not specifically address this situation. Accordingly, on August 5, 2020, the parties stipulated to the dismissal of the Court of Chancery action.

On October 6, 2020, Theravance Biopharma initiated a new arbitration against the Company and TRC, challenging Innoviva’s authority as manager of TRC to cause TRC to pursue non-Trelegy related investment opportunities and again alleging that Innoviva is required to cause TRC to distribute substantially all royalty proceeds from GSK. The hearing in respect of the arbitration was conducted from February 16, 2021 through February 19, 2021. Post-arbitration oral argument was heard on March 8, 2021. On March 30, 2021, the arbitrator issued a final decision. The arbitrator ruled that Innoviva did not breach the Operating Agreement or its fiduciary duties by withholding royalties to pursue non-Trelegy-related investment opportunities. Additionally, the arbitrator ruled that the Company is entitled to indemnification from TRC for 100% of its fees and expenses reasonably incurred in connection with the arbitration.

On April 15, 2021, the Company filed a Verified Complaint in the Court of Chancery to confirm the arbitration award. On May 19, 2021, Theravance Biopharma submitted an answer to the Verified Complaint and filed a Motion to Modify the Arbitral Award, alleging that it contained a mathematical error. The parties filed a proposed stipulation to remand the motion to Chancellor Chandler for his consideration, which the Court of Chancery granted. On June 25, 2021, Innoviva submitted a brief to Chancellor Chandler in opposition to the motion and on July 15, 2021, Theravance Biopharma submitted a reply brief. On August 6, 2021, Chancellor Chandler issued a modified final award, which did not affect any of his ultimate conclusions. The modified award was confirmed by the Court of Chancery on September 16, 2021.

1. Description of Operations and Summary of Significant Accounting Policies

Description of Operations

Innoviva Inc. (referred to as “Innoviva”, the “Company”, or “we” and other similar pronouns) is a company with a portfolio of royalties and other healthcare assets. Our royalty portfolio contains respiratory assets partnered with Glaxo Group Limited (“GSK”), including RELVAR®/BREO® ELLIPTA® (fluticasone furoate/ vilanterol, “FF/VI”), ANORO® ELLIPTA® (umeclidinium bromide/ vilanterol, “UMEC/VI”) and TRELEGY® ELLIPTA® (the combination FF/UMEC/VI). 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%. Innoviva is also entitled to 15% of royalty payments made by GSK under its agreements originally entered into with us, and since assigned to Theravance Respiratory Company, LLC (“TRC”), including TRELEGY® ELLIPTA® and any other product or combination of products that may be discovered or developed in the future under the LABA Collaboration Agreement and the Strategic Alliance Agreement with GSK (referred to herein as the “GSK Agreements”), which have been assigned to TRC other than RELVAR®/BREO® ELLIPTA® and ANORO® ELLIPTA®.

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) for interim financial information. Accordingly, they do not include all of the information and notes required by US GAAP for complete financial statements. In our opinion, the unaudited consolidated financial statements have been prepared on the same basis as audited consolidated financial statements and include all adjustments, consisting of only 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, 2021 or any other period.

The accompanying unaudited consolidated financial statements include the accounts of Innoviva, our wholly-owned subsidiaries and certain variable interest entities 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 (loss) attributable to noncontrolling interest in our unaudited 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 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, 2020 filed with the Securities and Exchange Commission (“SEC”) on February 25, 2021 (“2020 Form 10-K”).

Variable Interest Entities

We evaluate our ownership, contractual and other interest in entities to determine if they are variable interest entities (“VIE”). We evaluate whether we have a variable interest in those entities and the nature and extent of those interests. Based on our evaluation, if we determine we are the primary beneficiary of a VIE, we consolidate the entity in our financial statements.

Equity Investments

We invest from time to time in equity securities of private or public companies. If we determine that we have control over these companies under either voting or VIE models, we include them in our 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 equity 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 and long-term investments, net on the 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 an equity security without a readily determinable fair value using the measurement alternative described in ASC Topic 825. This measurement alternative 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.

Revenue Recognition

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.

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 have the ability to 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.

Accounting Pronouncement Adopted by the Company

In December 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes”, which is intended to simplify various aspects related to accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2020, with early adoption permitted. We adopted ASU 2019-12 effective January 1, 2021. The adoption did not have a material impact on our consolidated financial statements.

In October 2020, the FASB issued ASU 2020-10, Codification Improvements. This ASU improves the codification by ensuring that all guidance that requires or provides an option for an entity to provide information in the notes to financial statements is codified in the disclosure section of the codification. The ASU also clarifies various topics in the codification so that entities can apply guidance more consistently. The ASU is effective for fiscal years beginning after December 15, 2020. We adopted ASU 2020-10 effective January 1, 2021. The adoption did not have a material impact on our consolidated financial statements.

Recently Issued Accounting Standards or Updates Not Yet Adopted

In August 2020, the FASB issued ASU 2020-06, Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which is intended to simplify the accounting for convertible instruments by removing certain separation models in Subtopic 470-20 for convertible instruments. The ASU is effective for fiscal years beginning after December 15, 2021, and for interim periods within those fiscal years with early adoption permitted. We are currently in the process of evaluating the effects of the provisions of ASU 2020-06 on our consolidated financial statements.

Net Income Per Share

Net Income Per Share

2. Net Income Per Share

Basic net income per share attributable to Innoviva stockholders is computed by dividing net income attributable to Innoviva stockholders by the weighted-average number of shares of common stock outstanding. Diluted net income per share attributable to Innoviva stockholders is computed by dividing net income attributable to Innoviva stockholders by the weighted-average number of

shares of common stock and dilutive potential common stock equivalents then outstanding. Dilutive potential common stock equivalents include the assumed exercise, vesting and issuance of employee stock awards using the treasury stock method, as well as common stock issuable upon assumed conversion of our convertible subordinated notes due 2023 (the “2023 Notes”) using the if converted method.

Our convertible senior notes due 2025 (the “2025 Notes”) are convertible, based on the applicable conversion rate, into cash, shares of our common stock or a combination thereof, at our election. Our current intent is to settle the principal amount of the 2025 Notes in cash upon conversion. The impact of the assumed conversion premium to diluted net income per share is computed using the treasury stock method. As the average market price per share of our common stock as reported on The Nasdaq Global Select Market was lower than the initial conversion price of $17.26 per share, there was no dilutive effect of the assumed conversion premium for the three and nine months ended September 30, 2021 and 2020, respectively.

The following table shows the computation of basic and diluted net income per share for the three and nine months ended September 30, 2021 and 2020:

Pulmoquine Therapeutics, Inc.

In April 2020, we purchased 5,808,550 shares of Series A preferred stock of Pulmoquine for $5.0 million in cash. These shares represent a majority voting interest in Pulmoquine. Pulmoquine is a biotechnology company focused on the research and development of an aerosolized formulation of hydroxychloroquine to treat respiratory infections. In August 2021, the directors and stockholders of Pulmoquine voted to cease and terminate all operations and activities of Pulmoquine as soon as practicable. In September 2021, we received a net distribution of $2.3 million in cash related to the voluntary dissolution of Pulmoquine. The dissolution will be finalized in the fourth quarter of 2021.

As of September 30, 2021 and December 31, 2020, Pulmoquine’s total assets, mainly attributable to cash and cash equivalents, were $0.2 million and $3.5 million, respectively. Pulmoquine does not generate revenue. Total operating expense was $0.5 million and $0.7 million for the three and nine months ended September 30, 2021 respectively. Total operating expense was $1.1 million and $1.7 million for the three and nine months ended September 30, 2020.

ISP Fund LP

In December 2020, Innoviva Strategic Partners LLC, our wholly owned subsidiary (“Strategic Partners”), contributed $300.0 million to ISP Fund LP (the “Partnership”) for investing in “long” positions in the healthcare, pharmaceutical and biotechnology sectors and became a limited partner. The general partner of the Partnership (“General Partner”) is an affiliate of Sarissa Capital.

In May 2021, Strategic Partners received a distribution of $110.0 million from the Partnership to provide funding to Innoviva for a strategic repurchase of shares held by GSK. Pursuant to the letter agreement entered into between Strategic Partners, the Partnership and Sarissa Capital Fund GP LP on May 20, 2021, Strategic Partners is obligated to make additional capital contributions to the Partnership in an aggregate amount equal to the amount of the distribution ($110.0 million) prior to March 31, 2022. The capital contributions will then be subject to a 36-month lock up period from the contribution date.

As of September 30, 2021, we continued to hold 100% of the economic interest of the Partnership. As of September 30, 2021 and December 31, 2020, total assets of the Partnership were $228.9 million and $299.3 million, respectively, of which all were attributable to equity and long-term investments. During the three and nine months ended September 30, 2021, the Partnership incurred $0.2 million and $1.5 million, respectively, of investment-related expenses, net of investment-related income. During the three and nine months ended September 30, 2021, the Partnership recorded net unrealized gains of $10.1 million and $30.6 million, respectively, and net realized gains of $10.5 million during the nine months ended September 30, 2021 as changes in fair values of equity and long-term investments, net on the consolidated statements of income.

Equity Investment in Armata

During the first quarter of 2020, Innoviva acquired 8,710,800 shares of common stock and an equal number of warrants of Armata Pharmaceuticals, Inc. (“Armata”) for $25.0 million in cash. Armata is a clinical stage biotechnology company focused on precisely targeted bacteriophage therapeutics for antibiotic-resistant infections.

On January 26, 2021, Innoviva Strategic Opportunities LLC (“ISO”), our wholly owned subsidiary, entered into a securities purchase agreement with Armata to acquire 6,153,847 shares of Armata common stock and warrants to purchase 6,153,847 additional shares of Armata common stock for approximately $20.0 million. The investment was closed in two tranches on January 26, 2021 and March 17, 2021. The investments support Armata’s ongoing advancement of its bacteriophage development programs. The additional investment in the first quarter of 2021 increased Innoviva and ISO’s combined ownership to 59.6% as of March 31, 2021. Armata entered into a voting agreement with the Company and ISO, pursuant to which the Company and ISO agreed not to vote or take any action by written consent with respect to any common shares held by the Company and ISO that represent, in the aggregate, more than 49.5% of the total number of shares of Armata’s common stock issued and outstanding as of the record date for voting on the matters related to election or removal of Armata’s board members. As of September 30, 2021, three of the eight members of Armata’s board of directors are also members of the board of directors of Innoviva. As of September 30, 2021 and December 31, 2020, we owned approximately 59.5% and 46.6%, respectively, of Armata’s common stock.

The investment in Armata provides Innoviva and ISO the ability to have significant influence, but not control over Armata’s operations. Based on our evaluation, we determined that Armata is a VIE, but Innoviva and ISO are not the primary beneficiary of the VIE. We continue to elect the fair value option to account for both Armata’s common stock and warrants. The fair value of Armata’s common stock is measured based on its closing market price. The warrants purchased in 2020 and 2021 have an exercise price of $2.87 and $3.25 per share, respectively. All warrants are exercisable immediately within five years from the issuance date of the warrants and include a cashless exercise option. We use the Black-Scholes-Merton pricing model to estimate the fair value of these warrants with the following input assumptions: Armata’s closing market price on the valuation date, the risk-free interest rate computed based on the U.S. Treasury yield, the remaining contractual term as the expected term, and the expected stock price volatility calculated based on the historical volatility of the common stock of Armata and its peer companies.

As of September 30, 2021, the fair values of Armata’s common stock and warrants were estimated at $53.8 million and $35.5 million, respectively. As of December 31, 2020, the fair values of Armata’s common stock and warrants were estimated at $26.0 million and $18.0 million, respectively. The total fair value of both financial instruments in the amount of $89.3 million and $44.0 million was recorded as equity and long-term investments on the consolidated balance sheets as of September 30, 2021 and December 31, 2020, respectively. During the three and nine months ended September 30, 2021, we recorded $11.6 million unrealized loss and $25.3 million unrealized gains, respectively, as changes in fair values of equity and long-term investments, net on the consolidated statements of income. During the three and nine months ended September 30, 2020, we recorded $12.4 million unrealized loss and $23.0 million unrealized gains, respectively, as changes in fair values of equity and long-term investments, net on the consolidated statements of income.

Equity Investment in Entasis

During the second quarter of 2020, we purchased 14,000,000 shares of common stock as well as warrants to purchase 14,000,000 additional shares of common stock of Entasis Therapeutics, Inc. (“Entasis”) for approximately $35.0 million in cash. Entasis is a clinical-stage biotechnology company focused on the discovery and development of novel antibacterial products.

During the third quarter of 2020, we purchased 4,672,897 shares of Entasis common stock as well as warrants to purchase 4,672,897 additional shares of its common stock for approximately $12.5 million in cash. Innoviva has a right to designate two members to Entasis’ board. As of September 30, 2021, no Innoviva designees are serving on Entasis’ six-member board.

On May 3, 2021, ISO entered into a securities purchase agreement with Entasis to acquire 10,000,000 shares of Entasis common stock and warrants to purchase 10,000,000 additional shares of Entasis common stock for approximately $20.0 million. The investment was closed in two tranches on May 3, 2021 and June 11, 2021. This investment supports the continued development of Entasis’ novel pipeline of pathogen-targeted antibacterial product candidates. As of September 30, 2021, we owned approximately 60.6% of Entasis’ common stock. As of December 31, 2020, we owned approximately 51.0% of Entasis’ common stock.

The investment in Entasis provides Innoviva the ability to have significant influence, but not control over Entasis’ operations. Based on our evaluation, we determined that Entasis is a VIE, but Innoviva is not the primary beneficiary of the VIE. We elected the fair value option to account for both Entasis’s common stock and warrants at fair value. The fair value of Entasis’ common stock is measured based on its closing market price at each balance sheet date. The warrants have an exercise price of $2.50 per share and $2.675 per share for those warrants acquired in the second and third quarter of 2020, respectively. The warrants acquired in the second quarter of 2021 have an exercise price of $2.00 per share. All of the warrants are exercisable immediately within five years from the issuance date of the warrants and include a cashless exercise option. We use the Black-Scholes-Merton pricing model to estimate the fair value of these warrants.

As of September 30, 2021, the fair values of Entasis’s common stock and warrants were estimated at $95.8 million and $70.4 million, respectively. As of December 31, 2020, the fair values of Entasis’s common stock and warrants were estimated at $46.1 million and $31.9 million, respectively. The total fair value of both financial instruments in the amount of $166.2 million and $78.0 million was recorded as equity and long-term investments on the consolidated balance sheets as of September 30, 2021 and December 31, 2020, respectively. During the three and nine months ended September 30, 2021, we recorded $34.9 million and $68.1 million unrealized gains as changes in fair values of equity and long-term investments, net on the consolidated statements of income. During the three and nine months ended September 30, 2020, we recorded $17.0 million unrealized loss and $16.3 million unrealized gain, respectively, as changes in fair values of equity and long-term investments, net on the consolidated statements of income.

Equity Investment in InCarda

During the third quarter of 2020, TRC purchased 20,469,432 shares of Series C preferred stock and warrants to purchase 5,117,358 additional shares of Series C preferred stock of InCarda Therapeutics, Inc. (“InCarda”) for $15.0 million. $0.8 million was incurred for investment due diligence costs and recorded as part of the equity investment on the consolidated balance sheets. InCarda is a privately held biopharmaceutical company focused on developing inhaled therapies for cardiovascular diseases. As of September 30, 2021, one of InCarda’s eight board members is designated by TRC. As of September 30, 2021 and December 31, 2020, TRC held 13.0% and 13.4%, respectively, of InCarda’s outstanding equity.

The investment in InCarda does not provide TRC the ability to control or have significant influence over InCarda’s operations. Based on our evaluation, we determined that InCarda is a VIE, but TRC is not the primary beneficiary of the VIE. We account for our investment in the Series C preferred shares in InCarda using the measurement alternative. Under the measurement alternative, the equity investment is initially recorded at its allocated cost, but the carrying value may be adjusted through earnings upon an impairment or when there is an observable price change involving the same or a similar investment with the same issuer. As of September 30, 2021 and December 31, 2020, we recorded $15.8 million from our investment in InCarda’s Series C preferred stock as equity and long-term investments on the consolidated balance sheets. There was no impairment or other change to the value of InCarda’s Series C preferred stock as of September 30, 2021 and December 31, 2020.

The warrants are recorded at fair value and subject to remeasurement at each balance sheet date. The warrants are exercisable immediately with an exercise price of $0.7328 per share. In September 2021, TRC and InCarda entered into an amendment to extend the expiration date of the warrants from October 6, 2021 to March 31, 2022. We use the Black-Scholes-Merton pricing model to estimate the fair value of the warrants with the following input assumptions: the exercise price of the warrants, the risk-free interest rate computed based on the U.S. Treasury yield, the remaining contractual term as the expected term, and the expected stock price volatility calculated based on the historical volatility of the common stock of its peer companies. As of September 30, 2021 and December 31, 2020, the fair value of InCarda’s warrants was estimated at $0.6 million and $1.1 million, respectively, and recorded as equity and long-term investments on the consolidated balance sheets. During the three and nine months ended September 30, 2021, we recorded $0.1 million unrealized gain and $0.6 million unrealized loss, respectively, as changes in fair values of equity and long-term investments, net on the consolidated statements of income.

Equity Investment in ImaginAb

On March 18, 2021, TRC entered into a securities purchase agreement with ImaginAb, Inc. to purchase 4,051,724 shares of ImaginAb Series C preferred stock for $4.7 million. On the same day, TRC also entered into a securities purchase agreement with one of ImaginAb’s common stockholders to purchase 4,097,157 shares of ImaginAb common stock for $1.3 million. ImaginAb is a privately held biotechnology company focused on clinically managing cancer and autoimmune diseases via molecular imaging. $0.4 million was incurred for investment due diligence costs and execution and recorded as part of the equity investment on the consolidated balance sheets. As of September 30, 2021, one of ImaginAb’s five board members is designated by TRC. As of September 30, 2021, TRC held 12.5% of ImaginAb equity ownership.

The investment in ImaginAb does not provide TRC the ability to control or have significant influence over ImaginAb’s operations. Based on our evaluation, we determined that ImaginAb is a VIE, but TRC is not the primary beneficiary of the VIE. Because ImaginAb’s equity securities are not publicly traded and do not have a readily determinable fair value, we have accounted for our investment in ImaginAb’s Series C preferred stock and common stock using the measurement alternative. Under the measurement alternative, the equity investment is initially recorded at its allocated cost, but the carrying value may be adjusted through earnings upon an impairment or when there is an observable price change involving the same or a similar investment with the same issuer. As of September 30, 2021, $6.4 million was recorded as equity and long-term investments on the consolidated balance sheets. There was no change to the value of our investment in ImaginAB’s equity securities as of September 30, 2021.

Convertible Senior Notes Due 2025

In accordance with accounting guidance for debt with conversion and other options, we separately account for the liability and equity components of the 2025 Notes by allocating the proceeds between the liability component and the embedded conversion option (“equity component”) due to our ability to settle the conversion obligation of the 2025 Notes in cash, common stock or a combination of cash and common stock, at our option. The carrying amount of the liability component was calculated by measuring the fair value of a similar liability that does not have an associated convertible feature using the income approach. The allocation was performed in a manner that reflected our non-convertible debt borrowing rate for similar debt. The equity component of the 2025 Notes was recognized as a debt discount and represents the difference between the proceeds from the issuance of the 2025 Notes and the fair value of the liability of the 2025 Notes on the date of issuance. The excess of the principal amount of the liability component over its carrying amount (“debt discount”) is amortized to interest expense using the effective interest method over the term of the 2025 Notes. The equity component is not remeasured as long as it continues to meet the conditions for equity classification.

Our outstanding 2025 Notes balances consisted of the following:

	September 30,			December 31,

Description of Operations and Summary of Significant Accounting Policies

Basis of Presentation

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) for interim financial information. Accordingly, they do not include all of the information and notes required by US GAAP for complete financial statements. In our opinion, the unaudited consolidated financial statements have been prepared on the same basis as audited consolidated financial statements and include all adjustments, consisting of only 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, 2021 or any other period.

The accompanying unaudited consolidated financial statements include the accounts of Innoviva, our wholly-owned subsidiaries and certain variable interest entities 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 (loss) attributable to noncontrolling interest in our unaudited 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 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, 2020 filed with the Securities and Exchange Commission (“SEC”) on February 25, 2021 (“2020 Form 10-K”).

Variable Interest Entities

Variable Interest Entities

We evaluate our ownership, contractual and other interest in entities to determine if they are variable interest entities (“VIE”). We evaluate whether we have a variable interest in those entities and the nature and extent of those interests. Based on our evaluation, if we determine we are the primary beneficiary of a VIE, we consolidate the entity in our financial statements.

Equity Investments

Equity Investments

We invest from time to time in equity securities of private or public companies. If we determine that we have control over these companies under either voting or VIE models, we include them in our 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 equity 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 and long-term investments, net on the 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 an equity security without a readily determinable fair value using the measurement alternative described in ASC Topic 825. This measurement alternative 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.

Revenue Recognition

Revenue Recognition

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.

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 have the ability to 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.

Accounting Pronouncement Adopted by the Company

Accounting Pronouncement Adopted by the Company

In December 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes”, which is intended to simplify various aspects related to accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2020, with early adoption permitted. We adopted ASU 2019-12 effective January 1, 2021. The adoption did not have a material impact on our consolidated financial statements.

In October 2020, the FASB issued ASU 2020-10, Codification Improvements. This ASU improves the codification by ensuring that all guidance that requires or provides an option for an entity to provide information in the notes to financial statements is codified in the disclosure section of the codification. The ASU also clarifies various topics in the codification so that entities can apply guidance more consistently. The ASU is effective for fiscal years beginning after December 15, 2020. We adopted ASU 2020-10 effective January 1, 2021. The adoption did not have a material impact on our consolidated financial statements.

Recently Issued Accounting Standards or Updates Not Yet Adopted

Recently Issued Accounting Standards or Updates Not Yet Adopted

In August 2020, the FASB issued ASU 2020-06, Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which is intended to simplify the accounting for convertible instruments by removing certain separation models in Subtopic 470-20 for convertible instruments. The ASU is effective for fiscal years beginning after December 15, 2021, and for interim periods within those fiscal years with early adoption permitted. We are currently in the process of evaluating the effects of the provisions of ASU 2020-06 on our consolidated financial statements.
