NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)
Note 1 – Organization, Basis of Presentation and Liquidity
Zogenix, Inc., and subsidiaries (also referred to as Zogenix, we, our or us) is a global biopharmaceutical company committed to developing and commercializing therapies with the potential to transform the lives of patients and their families living with rare diseases. Our first rare disease therapy, Fintepla (fenfluramine) oral solution, has been approved by the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) for the treatment of seizures associated with Dravet syndrome, a rare, devastating, severe lifelong epilepsy. Fintepla is also currently under development in Japan. We also have two late-stage development programs underway: one for Fintepla for the treatment of seizures associated with Lennox-Gastaut syndrome (LGS), a rare childhood-onset epilepsy, and another for MT1621, an investigational novel substrate enhancement therapy for the treatment of TK2 deficiency, a rare genetic disorder.
We operate as a single operating segment engaged in the research, development and commercialization of pharmaceutical products, and our headquarters are located in Emeryville, California.
Basis of Presentation
The accompanying condensed consolidated financial statements have been prepared pursuant to generally accepted accounting principles in the United States (GAAP) for interim financial reporting and the rules and regulations of the Securities and Exchange Commission (SEC). The condensed consolidated financial statements do not include all of the information and note disclosures required by GAAP for complete financial statements and should therefore be read in conjunction with the consolidated financial statements and related notes included in our 2020 Annual Report on Form 10-K (2020 Form 10-K), which was filed with the SEC on March 1, 2021. In the opinion of management, these condensed consolidated financial statements reflect all adjustments, which are normal and recurring in nature, necessary for a fair statement of our financial position, results of operations and cash flows for the periods indicated. The results of operations for any interim period are not necessarily indicative of results of operations for any future period.
The accompanying condensed consolidated financial statements include the accounts of Zogenix, Inc. and its wholly-owned subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation.
Liquidity
As of June 30, 2021, our cash, cash equivalents and marketable securities totaled $393.3 million. Excluding gains from two discrete business divestitures, we have incurred significant net losses and negative cash flows from operating activities since inception, resulting in an accumulated deficit of $1.4 billion as of June 30, 2021. We expect to continue to incur significant operating losses and negative cash flows from operations to support the sales and marketing of Fintepla for Dravet syndrome in the U.S. and Europe, potential commercialization of Fintepla for LGS, as well as continuing to advance our clinical programs. Additionally, we are obligated to make future milestone payments that are contingent upon the successful achievement of certain development, regulatory and sales-based milestone events related to Fintepla and MT1621. Historically, we have relied primarily on the proceeds from equity and convertible debt offerings to finance our operations. Until such time, if ever, we can generate a sufficient amount of revenue to finance our cash requirements, we may need to continue to rely on additional financing to achieve our business objectives. However, we may not be able to secure such financing in a timely manner or on favorable terms, if at all, and this risk could be exacerbated by the impact of the ongoing COVID-19 pandemic on global economic conditions. Failure to raise sufficient capital when needed could require us to significantly delay, scale back or discontinue one or more of our product development programs or commercialization efforts or other aspects of our business plans, and our operating results and financial condition would be adversely affected.
Note 2 – Accounting Policies
Use of Estimates
The preparation of our condensed consolidated financial statements requires us to make estimates, judgments and assumptions that may affect the reported amounts of assets, liabilities, equity, revenues and expenses and related disclosure of contingent assets and liabilities. On an ongoing basis we evaluate our estimates, judgments and methodologies. We base our estimates on historical experience and on various other assumptions that we believe are reasonable, the results of which form the basis for making judgments about the
ZOGENIX, INC. | Q2 2021 Form 10-Q | 6
carrying values of assets, liabilities and equity and the amount of revenues and expenses. Actual results may differ from those estimates.
Significant Accounting Policies
The significant accounting policies and estimates used in the preparation of the accompanying condensed consolidated financial statements are described in Note 2, Summary of Significant Accounting Policies to the consolidated financial statements in our 2020 Form 10-K. There have been no material changes in our significant accounting policies during the six months ended June 30, 2021.
Recently Issued Accounting Pronouncements Not Yet Adopted
Account Standard Update (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) (ASU 2020-06) simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible debt instruments with cash conversion features. Specifically, ASU 2020-06 removes the existing guidance that we currently follow for our convertible senior notes, which requires entities to account for cash conversion features in equity separately from the host contract. These amendments are expected to result in more freestanding financial instruments qualifying for equity classification and, as a result, not accounted for as derivatives, as well as fewer embedded features requiring separate accounting from the host contract. In addition, ASU 2020-06 eliminates the treasury stock method when calculating diluted earnings per share for convertible instruments that can be settled in whole or in part with equity and requires the use of the if-converted method. Early adoption is permitted, but no earlier than the fiscal year beginning after December 15, 2020. The standard can be applied using a full or modified retrospective approach.
ASU 2020-06 will be effective for us as of January 1, 2022. When effective, we expect the accounting for our convertible senior notes as a single unit of account will: i) increase the carrying value of our convertible notes to be closer to its outstanding principal balance, ii) decrease our interest expense over the expected life of the financial instrument, and iii) result in the debt instrument’s effective interest rate to be closer to the stated coupon rate. In addition, the use of the more favorable treasury stock method, which allows an entity with a stated policy of settling convertible instruments with a combination of cash and shares to exclude shares issuable upon conversion that it expects to settle with cash when calculating diluted earnings per share, is no longer permitted. Even if we have the intent and ability to settle conversions by paying the conversion value in cash up to the principal amount being converted and any excess in shares, the adoption of ASU 2020-06 will require that we presume such instruments will be settled by issuance of shares (the “if-converted method”). As a result, our diluted earnings per share under ASU 2020-06 may be lower than if we were able to apply the treasury stock method when calculating the dilutive effect of our Notes in earnings per share. We are currently assessing the impact the adoption of this new standard will have on our consolidated financial statements and related disclosures
Note 3 – Product Revenue and Concentration of Credit Risks
Net Product Sales
Fintepla is distributed in the U.S. through an exclusive arrangement with a specialty distributor, who is our customer. The specialty distributor subsequently resells our product through its related specialty pharmacy provider to patients and health care providers. Separately, we have or may enter into payment arrangements with various third-party payers including pharmacy benefit managers, private healthcare insurers and government healthcare programs who provide coverage and reimbursement for our products that have been proscribed to a patient.
We distribute Fintepla in Europe (currently, in Germany and France) through a third-party logistics provider (3PL) for distribution to pharmacies in those countries. The pharmacies are our customers, who subsequently resell our product directly to patients and health care providers.
For the three months ended June 30, 2021, total net product sales generated from Fintepla was $17.5 million and consisted of $15.5 million from sales in the United States, with the remainder from sales in Germany and France. For the six months ended June 30, 2021, total net product sales generated from Fintepla was $29.9 million and consisted of $26.9 million from sales in the United States, with the remainder from sales in Germany and France. Fintepla was approved by the FDA in June 2020 and the EMA in December 2020.
We record product revenue at the net sales price (transaction price), which includes estimates of consideration payable to our customers and third-party payers for which reserves are established and that result from government rebates, chargebacks, co-pay assistance, prompt-payment discounts and other allowances that are offered under arrangements between us, our customers, and third-party payers related to the sales of Fintepla.

We generally invoice our customers and recognize revenue once our performance obligations are satisfied, at which point payment is unconditional. Accordingly, our arrangements with customers did not give rise to contract assets or liabilities during the six months ended June 30, 2021.
Concentration of Credit Risk and Major Customers
As is common in the pharmaceutical industry for products treating rare diseases, Fintepla is distributed through exclusive arrangements with a specialty distributor in the U.S. and through a 3PL who distributes to pharmacy providers throughout Germany. As a result, our accounts receivable balance at June 30, 2021 is highly concentrated with our U.S. customer, which accounted for over 80% of the balance and over 80% of net product revenue for the three and six months ended June 30, 2021. Accounts receivable are stated net of an allowance that reflects our current estimate of credit losses expected to occur over the life of the receivable. Estimates of our allowance for credit losses consider a number of factors including existing contractual payment terms, individual customer circumstances, historical payment patterns of our customers, a review of the local economic environment and its potential impact on expected future customer payment patterns. As of June 30, 2021 and December 31, 2020, we believe that the allowances for doubtful accounts, if any, are adequate based on our analysis of the specific business circumstances and expectations of collection for each of the underlying accounts.
Note 4 – Collaboration Arrangement
Nippon Shinyaku Co., Ltd
In March 2019, we entered into an agreement (Shinyaku Agreement) with Nippon Shinyaku Co., Ltd. (Shinyaku) for the exclusive distribution of Fintepla in Japan for the treatment of Dravet syndrome and LGS. No development rights or intellectual property licenses were transferred. As part of the Shinyaku Agreement, we are responsible for completing the global clinical development and all regulatory approval activities for Fintepla to support the submission of new drug applications in Japan for Dravet syndrome and LGS. Upon regulatory approval of Fintepla in Japan, Shinyaku will act as our exclusive distributor for Fintepla and will be responsible for the commercialization activities including the promotion, marketing, sale and distribution of Fintepla in Japan.
Shinyaku has agreed to support development and regulatory approval of Fintepla in Japan by actively participating in the design of non-clinical, clinical and manufacturing requirements needed for regulatory submission, actively planning and participating in product labeling decisions and discussions with the Japanese Ministry of Health, Labor and Welfare (MHLW) and obtained distribution exclusivity through the payment of an initial fixed consideration. The collaborative activities under the Shinyaku Agreement prior to regulatory approval are within the scope of the accounting guidance related to collaborative arrangements.
Pursuant to the terms of the agreement, Shinyaku agreed to make aggregate fixed payments of $20.0 million in scheduled installments over a two-year period from the date of the agreement. As of June 30, 2021, all fixed consideration has been received. In addition, we can earn up to $66.0 million from Shinyaku for the achievement of certain regulatory milestones for the treatment of Dravet syndrome and LGS. At contract inception and through June 30, 2021, the regulatory milestone variable consideration was fully constrained as the achievement of the events tied to these regulatory milestone payments was highly dependent on factors outside our control.
We can earn up to an additional $42.5 million tied to the achievement of certain net sales milestones by Shinyaku through the term of the agreement, which generally expires in 2045. Shinyaku will only become a customer and subject to revenue from contracts from customers accounting guidance after regulatory approval of Fintepla in Japan occurs and Shinyaku places purchase orders with us. To date, Shinyaku has not provided us with any purchase orders and thus no revenue has been recognized for the supply of Fintepla.
ZOGENIX, INC. | Q2 2021 Form 10-Q | 8
For the three and six months ended June 30, 2021, collaboration revenue under this arrangement was $1.3 million and $2.6 million, respectively, as compared to the same periods in 2020 of $1.0 million and $2.3 million, respectively. As of June 30, 2021, the deferred revenue balance of $9.7 million was classified as either current or net of current portion in the accompanying condensed consolidated balance sheets based on the period over which the collaboration revenue is expected to be recognized. We expect to recognize collaboration revenue related to these collaborative activities through the end of 2023.
Note 5 – Strategic License Agreement
Tevard Collaboration, Option and License Agreement
In October 2019, we entered into an option agreement with Tevard Biosciences (Tevard), a privately-held company focused on advancing novel gene therapies and other genetic epilepsies. In December 2020, we exercised the option on Tevard’s Dravet syndrome program and entered into a collaboration, option and license agreement with Tevard (the Tevard Agreement) and will be responsible for funding preclinical studies and clinical development for this program. The financial terms of the Tevard Agreement included an upfront payment of $5.2 million. In connection with the transaction, we also purchased a convertible promissory note issued by Tevard in the amount of $5.0 million. The note matures in December 2022 and carries interest at 3.5% per year. The note will automatically convert into equity securities issued by Tevard upon the occurrence of an equity financing transaction at a conversion price equal to the price paid per share by other investors of the financing transaction.
For the three and six months ended June 30, 2021, costs incurred to reimburse Tevard’s Dravet syndrome program of $0.8 million and $1.6 million were recorded as research and development expense. For the three and six months ended June 30, 2020, option maintenance fees of $1.5 million and $3.0 million incurred prior to our opt-in of Tevard’s Dravet syndrome program in December 2020 were immediately expensed to acquired in-process research and development costs.
At the inception of the agreement and through June 30, 2021, Tevard is a variable interest entity in which we held variable interests through our licensed Dravet syndrome program and convertible promissory note. We determined that we are not the primary beneficiary of Tevard as we do not have voting control or other forms of power to direct activities that most significantly impact Tevard’s economic performance.
At each reporting period, we evaluate the note receivable for current expected credit loss by considering factors such as historical experience, market data, issuer-specific factors, and current economic conditions. As of June 30, 2021, no provision for current expected credit losses was deemed necessary based on the expected timing of an equity financing that would result in the automatic conversion of the note to equity securities of Tevard and their existing cash on hand was sufficient to meet their operating requirements prior to the consummation of a financing transaction.
As of June 30, 2021, we do not have any current legal or contractual obligations to provide financing to Tevard and our maximum exposure to future loss is limited to the $5.0 million note receivable. While we have committed to fund the Dravet syndrome development program for Tevard’s early discovery activities, our obligation to fund these efforts is contingent upon continued involvement in the program and/or the lack of any adverse events which could cause the discontinuance of the program. Our exposure to future losses is limited as we have the unilateral right to terminate the agreement with 180 days advanced notice.

As of June 30, 2021, all marketable securities held have maturity dates within one year or less. We regularly review our available-for-sale marketable securities in an unrealized loss position and evaluate the current expected credit loss by considering factors such as historical experience, market data, issuer-specific factors, and current economic conditions. As of June 30, 2021, the aggregate difference between the amortized cost and fair value of each security in an unrealized loss position was de minimis. Since any provision for expected credit losses for a security held is limited to the amount the fair value is less than its amortized cost, no allowance for expected credit loss was deemed necessary at June 30, 2021.
See Note 7 for further information regarding the fair value of our financial instruments.
ZOGENIX, INC. | Q2 2021 Form 10-Q | 10
Note 7 – Fair Value Measurements
Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. A three-level valuation hierarchy has been established under GAAP for disclosure of fair value measurements. The valuation hierarchy is based on the transparency of inputs to the valuation of an asset or liability as of the measurement date. The three levels are defined as follows:
Level 1:Observable inputs such as quoted prices in active markets;
Level 2:Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and
Level 3:Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.
The following tables summarize assets and liabilities recognized or at fair value on a recurring basis as of June 30, 2021 and December 31, 2020:

(1)Fair value is determined by taking into consideration valuations obtained from third-party pricing services. The third-party pricing services utilize industry standard valuation models, for which all significant inputs are observable, either directly or indirectly, to estimate fair value. These inputs include reported trades of and broker/dealer quotes on the same or similar securities; issuer credit spreads; benchmark securities; and other observable inputs.
Contingent Consideration Liability
As of June 30, 2021, our contingent consideration liability consisted of sales-based milestones for Fintepla, which resulted from our 2014 acquisition of Brabant. The maximum amount of future contingent consideration (undiscounted) that we could be required to pay was $40.0 million.
The following table provides a reconciliation of our contingent consideration liability measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the three and six months ended June 30, 2021 and 2020 (in thousands):

(1)As of June 30, 2021 and 2020, outstanding obligations related to achieved milestones for the periods presented of $4.5 million and $15.0 million, respectively, were no longer contingent. As a result, the amounts have been reclassified from contingent consideration to accrued and other current liabilities on the condensed consolidated balance sheets.
For the three and six months ended June 30, 2021, the increases to the estimated fair value of the contingent consideration liability primarily reflects the interest component of contingent consideration related to the passage of time.
The following table summarizes the significant unobservable inputs used in the fair value measurement of our contingent consideration liability as of June 30, 2021.

(1)Unobservable inputs were weighted by the relative fair value of each sales-based milestone payment.
Fair Value Disclosures
Some of our financial instruments are not measured at fair value on a recurring basis but are recorded at amounts that approximate fair value due to their short-term nature. Such financial assets and financial liabilities include accounts receivable, note receivable, certain other current assets, accounts payable and accrued liabilities.
Convertible Senior Notes
As of June 30, 2021 and December 31, 2020, the estimated fair value of our convertible senior notes due 2027 was approximately $245.9 million and $260.5 million, respectively, and was determined based on a binomial lattice model with Level 2 inputs. When determining the estimated fair value of our Notes, we utilize a binomial lattice model which incorporates the terms and conditions of our convertible senior notes and market-based risk measurements that are indirectly observable, such as credit risk. The lattice model produces an estimated fair value based on changes in the price of the underlying common stock price over successive periods of time. An estimated yield based on comparable non-convertible debt instruments in the market is used to discount the cash flows.

Note 10 – Convertible Senior Notes
In September and October 2020, we issued $230.0 million aggregate principal amount of 2.75% convertible senior notes due 2027 (the Notes) and realized net proceeds of $222.5 million. The Notes are governed by an indenture (Indenture), dated as of September 28, 2020, between Zogenix and U.S. Bank National Association, as trustee. Under the Indenture, the Notes are senior, unsecured obligations of Zogenix, are equal in right of payment with its future senior, unsecured indebtedness of Zogenix, and structurally subordinated to all indebtedness and liabilities of its subsidiaries. Interest is payable semi-annually in arrears on April 1 and October 1 of each year, beginning on April 1, 2021 at a rate of 2.75% per year. The Notes mature on October 1, 2027, unless earlier repurchased, redeemed or converted. The Indenture contains customary terms and covenants and may become due and payable upon the occurrence of an event of default, but does not contain any financial covenants. As of June 30, 2021, we were in compliance with all covenants under the Indenture.
ZOGENIX, INC. | Q2 2021 Form 10-Q | 13
The Notes are convertible, subject to certain conditions described below, into shares of our common stock at an initial conversion rate of 41.1794 shares per $1,000 principal amount of the Notes, which represents an initial conversion price of approximately $24.28 per share, subject to adjustments upon the occurrence of certain events. Certain corporate events described in the Indenture may increase the conversion rate for holders who elect to convert their Notes upon the occurrence of certain corporate events. We also may choose to repurchase outstanding Notes through open-market transactions, including through a Rule 10b5-1 trading plan to facilitate open-market repurchases, or otherwise, from time to time.
Holders may convert the Notes in multiples of $1,000 principal amount at any time prior to October 1, 2027, but only in the following circumstances:
•during any calendar quarter ending after December 31, 2020, if our closing stock price exceeds 130% of the conversion price on each of at least 20 trading days of the last 30 consecutive trading days of the immediately preceding calendar quarter;
•during the five consecutive business day period after any 10 consecutive trading day period in which the Notes’ trading price is less than 98% of the product of our closing stock price times the conversion rate; or
•the occurrence of certain corporate events, such as a change of control, merger, default or liquidation.
In addition, holders may also convert their Notes at their option at any time beginning on July 1, 2027 until the close of business on the second scheduled trading day immediately before the maturity date for the Notes, without regard to the foregoing circumstances.
Upon conversion, we will pay or deliver, as the case may be, cash, shares of our common stock or a combination thereof at our election.
We may not redeem the Notes prior to October 7, 2024. On or after October 7, 2024, the Notes are redeemable for cash, in whole or in part (subject to minimum redemption amounts), at our option at any time, and from time to time, before the 40th scheduled trading day immediately before October 1, 2027, at a cash redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, but only if our closing stock price exceeds 130% of the conversion price on (1) each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on, and including, the trading day immediately before the date we send the related redemption notice; and (2) the trading day immediately before the date we send such notice. In addition, calling any Note for redemption will constitute a make-whole fundamental change (as defined in the Indenture) with respect to that Note, in which case the conversion rate applicable to the conversion of that Note will be increased in certain circumstances if it is converted after it is called for redemption.
In accounting for the issuance of the Notes, we separated the Notes between a liability component and an equity component utilizing applicable accounting guidance for convertible instruments that may be settled with a combination of cash and shares, at our election. This resulted in the recognition of $152.1 million as the liability component of the Notes. The carrying amount of the equity component of approximately $77.9 million, representing the conversion option, was determined by deducting the fair value of the liability component from the principal amount of the Notes. The difference between the principal amount of the Notes and the liability component (the debt discount) is amortized to interest expense using the effective interest method over the expected term of the Notes. The equity component of the Notes is included in additional paid-in capital in the condensed consolidated balance sheets. In accounting for debt issuance costs, we allocated the total amount incurred of $7.5 million to the liability and equity components using the same proportions as the principal amount of the Notes. Debt issuance costs attributable to the liability component of $4.9 million were recorded as debt discount and are being amortized to interest expense over the expected term of the Notes. Debt issuance costs attributable to the equity component of approximately $2.6 million were netted with the equity component within our condensed consolidated stockholders' equity.
The equity component balance of $75.3 million, net of allocated issuance costs, is not remeasured as long as the conversion option of the Notes continues to meet the conditions for equity classification. As of June 30, 2021, there have been no changes to the net carrying value of the equity component balance since the date of issuance of the Notes.

For the three and six months ended June 30, 2021, the effective interest rate on the liability component of the Notes was 9.9%, which remained unchanged from the date of issuance. The unamortized debt discount and issuance costs of $76.4 million as of June 30, 2021 will be amortized over the estimated remaining term of approximately 6.3 years. We had no interest expense for the same periods in 2020 as we had no borrowings.
During the three months ended June 30, 2021, the closing price of our common stock did not exceed 130% of the applicable conversion price of our Notes on at least 20 of the last 30 consecutive trading days of the quarter; furthermore, no other conditions allowing holders of the Notes to convert were met as of June 30, 2021. Therefore, the Notes are not convertible for the three months ending September 30, 2021 and are classified as long-term debt. Should the closing price conditions be met in a future quarter, the Notes will be convertible at the holders’ option during the immediately following quarter. Based on the closing price of our common stock of $17.28 per share on June 30, 2021, the if-converted value of the Notes was less than the outstanding principal balance.
Note 11 – Common Stock and Stock-Based Compensation
Increase in Authorized Shares of Common Stock
In May 2021, our stockholders approved an amendment to our Fifth Amended and Restated Certificate of Incorporation to increase the total number of authorized shares of our common stock from 100,000,000 to 200,000,000 shares. The increase in the authorized common shares was effected pursuant to a Certificate of Amendment of our Fifth Amended and Restated Certificate of Incorporation filed with the State of Delaware on May 28, 2021 and was effective as of such date.
2010 Equity Incentive Award Plan
Under our 2010 Equity Incentive Award Plan, as amended and restated effective May 22, 2019 (the Prior 2010 Plan), the aggregate number of shares with respect to which awards may be granted was 11,500,000 shares. The various types of awards that may be granted include stock options, stock appreciation rights, restricted stock units, restricted stock and other stock-based awards, any of which may be performance-based.
In May 2021, our board of directors adopted, and our stockholders approved, an amendment and restatement of the Prior 2010 Plan. The 2010 Equity Incentive Award Plan, as amended and restated effective May 27, 2021 (the 2010 Plan), increased the aggregate number of shares authorized for issuance under the plan from 11,500,000 to 16,000,000 shares, and an extension of the expiration date of the Prior 2010 Plan from March 2029 to May 2031. At June 30, 2021, approximately 6.9 million shares were available for future issuance under our 2010 Plan.
2021 Employment Inducement Equity Incentive Award Plan
In May 2021, our board of directors approved the adoption of the Zogenix, Inc. 2021 Employment Inducement Equity Incentive Award Plan (2021 Inducement Plan), pursuant to which we reserved 1,000,000 shares of our
ZOGENIX, INC. | Q2 2021 Form 10-Q | 15
common stock (subject to customary adjustments in the event of a change in capital structure). The 2021 Inducement Plan provides for the grant of non-statutory stock options, restricted stock units and other incentive awards and was adopted without stockholder approval pursuant to Rule 5635(c)(4) of the Nasdaq Listing Rules.
The terms and conditions of the 2021 Inducement Plan are substantially similar to our 2010 Plan, but with such other terms and conditions intended to comply with the Nasdaq inducement award rules. In accordance with Rule 5635(c)(4) of the Nasdaq Listing Rules, the only persons eligible to receive grants of equity awards under the 2021 Inducement Plan are individuals who were not previously a Zogenix employee or director, or following a bona fide period of non-employment, as an inducement material to such persons entering into employment with us.
At June 30, 2021, no grants have been made from the 2021 Inducement Plan and 1,000,000 shares were available for future issuance.

For the six months ended June 30, 2021, we granted approximately 492,000 PSUs to employees and executive officers. The PSUs are subject to vesting based on various performance conditions including achievement of certain regulatory milestones, net product revenue targets and the number of patients on reimbursed therapy, subject to continued service by the employee. Compensation expense related to equity-based awards with performance conditions and terms that provide for a graded vesting schedule is recognized over the requisite service period on a straight-line basis for each separately vesting tranche of the award, and is based on the expected satisfaction of the performance conditions at each reporting date. For performance conditions associated with regulatory milestones, we determined the outcome is not probable of being achieved unless and until the occurrence of the event. As a result, compensation expense will only be recognized, at a point in time, when regulatory approval occurs. We expect stock-based compensation will fluctuate from period to period based on the timing of achievement of regulatory milestones and such fluctuations may be material. For performance conditions associated with the net product revenue and the number of patients receiving reimbursed therapy, we determined the outcome is probable of being achieved and stock-based compensation expense is recognized commencing at the grant date over the implicit service period.

Note 12 – Net Loss Per Share
Basic net loss per share is calculated by dividing net loss by the weighted average number of shares outstanding for the period. Diluted net loss per share is calculated by dividing net loss by the weighted average number of shares of common stock and potential dilutive common stock equivalents outstanding during the period if the effect is dilutive. Our potentially dilutive shares of common stock include outstanding stock options, restricted stock units, warrants to purchase common stock and rights under our Notes.
A reconciliation of the numerators and denominators used in computing net loss per share is as follows (in thousands, except per share amounts):

Note 13 - Income Taxes
We record a tax provision or benefit for interim periods using an estimated annual effective tax rate. This rate is applied to the current year-to-date pre-tax income or loss to determine the income tax provision or benefit allocated to the interim period. The income tax effects of unusual or infrequent items including a change in the valuation allowance as a result of a change in judgment about the realizability of the related deferred tax asset are excluded from the estimated annual effective tax rate and are required to be discretely recognized in the interim period they occur.
For the three and six months ended June 30, 2021, there was no provision for income taxes as we incurred pretax losses and as of June 30, 2021, we maintained a full valuation allowance against our net deferred tax assets.
For the three and six months ended June 30, 2020, we recognized an income tax benefit of $17.4 million on pretax loss of $70.7 million and $96.5 million, respectively, related to the completion of our in-process research program upon approval of Fintepla for marketing by the FDA. Until June 2020, our net deferred tax liability was related to book and tax basis differences for our indefinite-lived Fintepla IPR&D intangible asset that was acquired through the October 2014 acquisition of Brabant Pharma Limited. Previously, this deferred tax liability was not considered to be a source of income for purposes of establishing our deferred tax asset valuation allowance due to the uncertainty associated with the timing of reversals for this temporary tax difference. Upon FDA approval of Fintepla in June 2020, the indefinite-lived asset was reclassified to a finite-lived intangible asset and was subject to amortization over its estimated useful life. Because the detail scheduling of the timing of reversal for this temporary tax difference became available, the deferred tax liability associated with this finite-lived intangible asset was considered to be a source of income when assessing the realizability of our deferred tax assets as of June 30, 2020. We therefore recorded a $17.4 million income tax benefit for the three and six months ended June 30, 2020 with a corresponding reduction to our valuation allowance on deferred tax assets. The income tax benefit recognized for the three and six months ended June 30, 2020 included the effects of foreign exchange differences on remeasurement of the deferred tax liability. An immaterial portion of the adjustment for foreign exchange differences was related to prior periods.
Note 14 – United Kingdom (U.K.) Research and Development (R&D) Tax Relief Scheme
We conduct extensive research and development activities that benefit from U.K.’s small and medium-sized enterprises (SMEs) R&D tax relief scheme. Under this tax relief scheme, a SME can make an election (i) to receive an enhanced U.K. tax deduction on its eligible R&D activities or, when an SME entity is in a net operating loss position, or (ii) to surrender net operating losses that arise from its eligible R&D activities in exchange for a cash payment from the U.K. tax authorities. As the tax incentives may be received without regard to an entity’s actual tax liability, they are not subject to accounting for income taxes. Amounts recognized by us for cash payment claims under the SME R&D tax relief scheme are recorded as a component of other income after an election for tax relief has been made by submitting a claim for a discrete tax year and collectability is deemed probable and reasonably assured.
In December 2019, we elected to surrender net operating losses by submitting claims to receive cash payments of $9.9 million and $9.8 million related to our 2017 and 2018 tax years, respectively. Upon approval of our submitted claims by the U.K. tax authorities in the first quarter of 2020, we recorded income of $19.7 million as a component of other income on the condensed consolidated statement of operations. For our 2019 and 2020 tax years, we have not yet decided whether to seek tax relief by surrendering some of our losses for a tax credit cash rebate claim or electing to receive enhanced U.K. tax deductions on our eligible research and development

activities. Under the U.K.’s tax legislation, there is a two-year window after the end of a tax year to seek relief under this tax relief scheme.
Note 15 – Subsequent Events
On July 21, 2021, we received a letter dated July 20, 2021, notifying us that Apotex Inc. (Apotex) submitted an ANDA to the FDA for a generic version of 2.2 mg base/ml Fintepla (fenfluramine hydrochloride) that contains Paragraph IV certifications with respect to two of our patents covering Fintepla, U.S. Patent Nos. 10,603,290, expiration date August 2, 2037; and 10,452,815, expiration date October 22, 2039. These patents are listed in the FDA’s list of Approved Drug Products with Therapeutic Equivalence Evaluations, commonly referred to as the Orange Book, for Fintepla. The certifications allege these patents are invalid or will not be infringed by the manufacture, use or sale of Apotex’s fenfluramine hydrochloride oral solution, 2.2 mg base/ml product. In the United States, approved ANDA generic drugs are usually interchangeable with the branded innovator drug. We anticipate initiating litigation against Apotex over the validity and infringement of the patents covering Fintepla.
