(In thousands, except where otherwise noted)

1. Organization and Summary of Significant Accounting Policies

The Company

AcelRx Pharmaceuticals, Inc., or the Company, or AcelRx, was incorporated in Delaware on July 13, 2005 as SuRx, Inc. The Company subsequently changed its name to AcelRx Pharmaceuticals, Inc. The Company’s operations are based in Hayward, California.

AcelRx is a specialty pharmaceutical company focused on the development and commercialization of innovative therapies for use in medically supervised settings. DSUVIA® (known as DZUVEO® in Europe) and Zalviso® are both focused on the treatment of acute pain, and each utilize sufentanil, delivered via a non-invasive route of sublingual administration, exclusively for use in medically supervised settings. On November 2, 2018, the U.S. Food and Drug Administration, or FDA, approved DSUVIA for use in adults in a certified medically supervised healthcare setting, such as hospitals, surgical centers, and emergency departments, for the management of acute pain severe enough to require an opioid analgesic and for which alternative treatments are inadequate. The commercial launch of DSUVIA in the United States occurred in the first quarter of 2019. In June 2018, the European Commission, or EC, granted marketing approval of DZUVEO for the management of acute moderate to severe pain in adults in medically monitored settings. AcelRx is further developing a distribution capability and commercial organization to continue to market and sell DSUVIA in the United States. In geographies where AcelRx decides not to commercialize products by itself, the Company may seek to out-license commercialization rights. The Company currently intends to commercialize and promote DSUVIA/DZUVEO outside the United States with one or more strategic partners, and, in July 2021, entered into a License and Commercialization Agreement with Laboratoire Aguettant, or Aguettant, for Aguettant to commercialize DZUVEO in the European Union, Norway, Iceland, Liechtenstein, Andorra, Vatican City, Monaco, Switzerland and the United Kingdom, or the DZUVEO Agreement. Zalviso was approved in Europe and was commercialized by Grünenthal GmbH, or Grünenthal, through May 12, 2021 (see Termination of Grünenthal Agreements below). In July 2022, the European Marketing Authorization for Zalviso was withdrawn. In July 2021, the Company also entered into a separate License and Commercialization Agreement with Aguettant pursuant to which the Company obtained the exclusive right to develop and, subject to FDA approval, commercialize in the United States (i) an ephedrine pre-filled syringe containing 10 ml of a solution of 3 mg/ml ephedrine hydrochloride for injection, and (ii) a phenylephrine pre-filled syringe containing 10 ml of a solution of 50 mcg/ml phenylephrine for injection.

On January 7, 2022, the Company acquired Lowell Therapeutics, Inc., or Lowell, a privately held company (see Note 4. “Asset Acquisition” below), and, as a result acquired Niyad™, a regional anticoagulant for the dialysis circuit during continuous renal replacement therapy for acute kidney injury patients in the hospital, that the Company plans to study under an investigational device exemption, or IDE, and which has received Breakthrough Device Designation status from the FDA. While not approved for commercial use in the United States, the active drug component of Niyad, nafamostat, has been approved in Japan and South Korea as a regional anticoagulant for the dialysis circuit, disseminated intravascular coagulation, and acute pancreatitis. Niyad is a lyophilized formulation of nafamostat, a broad-spectrum, synthetic serine protease inhibitor, with anticoagulant, anti-inflammatory, and potential anti-viral activities. The second intended indication for Niyad is as a regional anticoagulant for the dialysis circuit for chronic kidney disease patients undergoing intermittent hemodialysis in dialysis centers. In addition, the Company acquired LTX-608, a proprietary nafamostat formulation for direct IV infusion that it intends to develop for the treatment of acute respiratory distress syndrome, or ARDS, and disseminated intravascular coagulation, or DIC.

Termination of Grünenthal Agreements

On December 16, 2013, AcelRx and Grünenthal entered into a Collaboration and License Agreement, or the License Agreement, which was amended effective July 17, 2015, and September 20, 2016, or the Amended License Agreement, which granted Grünenthal rights to commercialize the Zalviso PCA system, or the Product, in the 28 European Union, or EU, member states, at the time of the agreement, plus Switzerland, Liechtenstein, Iceland, Norway and Australia (collectively, the Zalviso Territory) for human use in pain treatment within, or dispensed by, hospitals, hospices, nursing homes and other medically supervised settings, (collectively, the Field). In September 2015, the EC granted marketing approval for the marketing authorization application, or MAA, previously submitted to the EMA, for Zalviso for the management of acute moderate-to-severe post-operative pain in adult patients. On December 16, 2013, AcelRx and Grünenthal entered into a Manufacture and Supply Agreement, or the MSA, and together with the License Agreement, the Agreements. Under the MSA, the Company exclusively manufactured and supplied the Product to Grünenthal for the Field in the Zalviso Territory. On July 22, 2015, the Company and Grünenthal amended the MSA, or the Amended MSA, effective as of July 17, 2015. The Amended MSA and the Amended License Agreement are referred to as the Grünenthal Agreements.

On May 18, 2020, the Company received a notice from Grünenthal that it had exercised its right to terminate the Grünenthal Agreements, effective November 13, 2020. The terms of the Grünenthal Agreements were extended to May 12, 2021 to enable Grünenthal to sell down its Zalviso inventory, a right it had under the Grünenthal Agreements. The rights to market and sell Zalviso in the Zalviso Territory reverted back to the Company on May 12, 2021. In July 2022, the European Marketing Authorization for Zalviso was withdrawn.

Termination of Royalty Monetization

On September 18, 2015, the Company sold the majority of the royalty rights and certain commercial sales milestones it was entitled to receive under the Amended License Agreement with Grünenthal to PDL BioPharma, Inc., or PDL, in a transaction referred to as the Royalty Monetization. On August 31, 2020, PDL announced it sold its royalty interest for Zalviso to SWK Funding, LLC, or SWK. On May 31, 2022, the Company entered into a Termination Agreement with SWK to fully terminate the Royalty Monetization for which the Company paid cash consideration of $0.1 million. Neither PDL nor SWK retains any further interest in the Royalty Monetization. Accordingly, effective May 31, 2022, the Royalty Monetization is no longer reflected on the Company’s consolidated financial statements or other records as a sale of assets to PDL or SWK, and all security interests and other liens of every type held by the parties to the Royalty Monetization have been terminated and automatically released without further action by any party. The $84.1 million gain on extinguishment of the liability related to the sale of future royalties is recognized in the condensed consolidated statements of operations as other income.

Liquidity and Going Concern

The condensed consolidated financial statements for the three and nine months ended September 30, 2022 were prepared on the basis of a going concern, which contemplates that the Company will be able to realize assets and discharge liabilities in the normal course of business. The termination of the Royalty Monetization resulted in net income for the nine months ended September 30, 2022; however, before this, the Company had incurred recurring operating losses and negative cash flows from operating activities since inception and expects to continue to incur operating losses and negative cash flows in the future. These conditions raise substantial doubt about the Company’s ability to continue as a going concern. Considering the Company’s current cash resources and its current and expected levels of operating expenses for the next twelve months, management expects to need additional capital to fund its planned operations prior to the 12 month anniversary of the date this Quarterly Report on Form 10-Q is filed with the United States Securities and Exchange Commission, or the SEC. Management may seek to raise such additional capital through public or private equity offerings, including under the Controlled Equity Offering^SM Sales Agreement, or the ATM Agreement, with Cantor Fitzgerald & Co., or Cantor, debt securities, monetize or securitize certain assets, refinance its loan agreement, enter into product development, license or distribution agreements with third parties, or divest DSUVIA in the United States, DZUVEO in Europe, or any of the Company’s product candidates. While management believes its plans to raise additional funds will alleviate the conditions that raise substantial doubt about the Company’s ability to continue as a going concern, these plans are not entirely within the Company’s control and cannot be assessed as being probable of occurring. Additional funds may not be available when the Company needs them on terms that are acceptable to the Company, or at all. If adequate funds are not available, the Company may be required to further reduce its workforce, reduce the scope of, or cease, the commercial launch of DSUVIA, or delay the development of its regulatory filing plans for its product candidates in advance of the date on which the Company’s cash resources are exhausted to ensure that the Company has sufficient capital to meet its obligations and continue on a path designed to preserve stockholder value. In addition, if additional funds are raised through collaborations, strategic alliances or licensing arrangements with third parties, the Company may have to relinquish rights to its technologies, future revenue streams or product candidates, or to grant licenses on terms that may not be favorable to the Company.

Reverse Stock Split

On September 23, 2022, at a special meeting of stockholders, the Company's stockholders authorized the Company’s Board of Directors to effect a reverse stock split of all outstanding shares of common stock in a range of 1-for-10 to 1-for-30. The Board of Directors subsequently approved a reverse stock split with a ratio of 1-for-20, or the Reverse Stock Split. On October 25, 2022, following the filing of a certificate of amendment to the Company’s amended and restated certificate of incorporation, every 20 shares of the Company's common stock that were issued and outstanding automatically converted into one outstanding share of common stock. The Reverse Stock Split affected all shares of common stock outstanding immediately prior to the effective time of the Reverse Stock Split, as well as the number of shares of common stock available for issuance under the Company's equity incentive and employee stock purchase plans. Outstanding stock options, restricted stock units and warrants were proportionately reduced and the respective exercise prices, if applicable, were proportionately increased. The Reverse Stock Split affected all holders of common stock uniformly and did not affect any stockholder's percentage of ownership interest. The par value of the Company's common stock remained unchanged at $0.001 per share and the number of authorized shares of common stock remained the same after the Reverse Stock Split.

As the par value per share of the Company's common stock remained unchanged at $0.001 per share, the change in the common stock recorded at par value has been reclassified to additional paid-in-capital on a retroactive basis. All references to shares of common stock, stock options, restricted stock units and warrants and per share data for all periods presented in the accompanying condensed consolidated financial statements and notes thereto have been adjusted to reflect the Reverse Stock Split on a retroactive basis.

Principles of Consolidation

The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and the rules and regulations of the SEC. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included.

Operating results for the three and nine months ended September 30, 2022, are not necessarily indicative of the results that may be expected for the year ending December 31, 2022, or any future period. The condensed consolidated balance sheet as of December 31, 2021, was derived from the Company’s consolidated audited financial statements as of December 31, 2021, included in the Company’s Annual Report on Form 10-K filed with the SEC on March 10, 2022. These condensed consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2021, which includes a broader discussion of the Company’s business and the risks inherent therein.

Reclassifications 

Certain prior year amounts in the consolidated financial statements have been reclassified to conform to the current year's presentation. In particular, the restricted cash classified as “Cash and cash equivalents” has been reclassified to “Restricted cash, net of current portion” in the condensed consolidated balance sheets as of December 31, 2021 and in the condensed consolidated statement of cash flows as of December 31, 2021, September 30, 2021 and December 31, 2020. See “—Cash, Cash Equivalents and Restricted Cash” below.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States, or GAAP, requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Management evaluates its estimates on an ongoing basis including critical accounting policies. Estimates are based on historical experience and on various other market-specific and other relevant assumptions that the Company believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ from those estimates.

Cash, Cash Equivalents and Restricted Cash

The Company considers all highly liquid investments with an original maturity (at date of purchase) of three months or less to be cash equivalents. Cash and cash equivalents consist of cash on deposit with banks.

On May 30, 2019, the Company entered into a Loan Agreement with Oxford Finance LLC, or Oxford, or the Lender. The Loan Agreement requires that the Company always maintain unrestricted cash of not less than $5.0 million in accounts subject to control agreements in favor of the Lender, tested monthly as of the last day of the month. The Company has classified these unrestricted funds as restricted cash on the condensed consolidated balance sheets.

The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the condensed consolidated balance sheets that sum to the total of the same such amounts in the condensed consolidated statement of cash flows:

Restructuring Costs

The Company's restructuring costs consist of employee termination benefit costs. Liabilities for costs associated with the cost reduction plan are recognized when the liability is incurred and are measured at fair value. One-time termination benefits are expensed at the date the Company notifies the employee, unless the employee must provide future service, in which case the benefits are expensed ratably over the future service period.

In May 2022, the Company initiated a reorganization that eliminated approximately 40% of its employees, primarily within the commercial organization. For the nine months ended September 30, 2022, the Company incurred approximately $0.5 million in employee termination benefits related to this restructuring, all of which has been paid. This headcount reduction was completed in the second quarter of 2022. No additional expenses are anticipated in connection with this cost reduction plan.

Significant Accounting Policies

The Company’s significant accounting policies are detailed in its Annual Report on Form 10-K for the year ended December 31, 2021. There have been no significant changes to the Company’s significant accounting policies during the nine months ended September 30, 2022, from those previously disclosed in its 2021 Annual Report on Form 10-K, except as follows:

Acquisitions

The Company evaluates acquisitions of assets and other similar transactions to assess whether or not the transaction should be accounted for as a business combination or asset acquisition by first applying a screen test to determine whether substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets. If so, the transaction is accounted for as an asset acquisition. If not, further determination is required as to whether or not the Company has acquired inputs and processes that have the ability to create outputs, which would meet the definition of a business. Significant judgment is required in the application of the screen test to determine whether an acquisition is a business combination or an acquisition of assets.

Acquisitions meeting the definition of business combinations are accounted for using the acquisition method of accounting, which requires that the purchase price be allocated to the net assets acquired at their respective fair values. In a business combination, any excess of the purchase price over the estimated fair values of the net assets acquired is recorded as goodwill.

For asset acquisitions, a cost accumulation model is used to determine the cost of an asset acquisition. Direct transaction costs are recognized as part of the cost of an asset acquisition. The Company also evaluates which elements of a transaction should be accounted for as a part of an asset acquisition and which should be accounted for separately. The cost of an asset acquisition, including transaction costs, is allocated to identifiable assets acquired and liabilities assumed based on a relative fair value basis. Goodwill is not recognized in an asset acquisition. Any difference between the cost of an asset acquisition and the fair value of the net assets acquired is allocated to the non-monetary identifiable assets based on their relative fair values. When a transaction accounted for as an asset acquisition includes an in-process research and development, or IPR&D, asset, the IPR&D asset is only capitalized if it has an alternative future use other than in a particular research and development project. For an IPR&D asset to have an alternative future use: (a) the Company must reasonably expect that it will use the asset acquired in the alternative manner and anticipate economic benefit from that alternative use, and (b) the Company’s use of the asset acquired is not contingent on further development of the asset subsequent to the acquisition date (that is, the asset can be used in the alternative manner in the condition in which it existed at the acquisition date). Otherwise, amounts allocated to IPR&D that have no alternative use are expensed. Asset acquisitions may include contingent consideration arrangements that encompass obligations to make future payments to sellers contingent upon the achievement of future financial targets. Contingent consideration is not recognized until all contingencies are resolved and the consideration is paid or probable of payment, at which point the consideration is allocated to the assets acquired on a relative fair value basis.

Net Income (Loss) per Share of Common Stock

Basic and diluted net income (loss) per common share, or EPS, are calculated in accordance with the provisions of FASB ASC Topic 260, Earnings per Share.

The Company’s Series A Redeemable Convertible Preferred Stock issued during the quarter ended September 30, 2022, met the definition of a participating security given their rights to participate in dividends if declared on common stock, which requires the Company to apply the two-class method to compute both basic and diluted net income or loss per share. The two-class method is an earnings allocation formula that treats participating securities as having rights to earnings that would otherwise have been available to common stockholders. In addition, as these securities are participating securities, the Company is required to calculate diluted net income or loss per share under the if-converted method in addition to the two-class method and utilize the most dilutive result. In periods where there is a net loss, no allocation of undistributed net loss to the Series A Redeemable Convertible Preferred stockholders is performed as the holders of these securities are not contractually obligated to participate in the Company’s losses.

For additional information regarding the net income (loss) per share, see Note 14 “Net Income (Loss) per Share of Common Stock”.

Recently Issued Accounting Pronouncements

Recently issued accounting pronouncements whose adoption may impact the Company are detailed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021. There have been no significant changes to recently issued accounting pronouncements whose adoption may impact the Company during the nine months ended September 30, 2022, from those previously disclosed in the Company’s 2021 Annual Report on Form 10-K.

2. Investments and Fair Value Measurement

Investments

The Company classifies its marketable securities as available-for-sale and records its investments at fair value. Available-for-sale securities are carried at estimated fair value based on quoted market prices or observable market inputs of almost identical assets, with the unrealized holding gains and losses included in accumulated other comprehensive income (loss). Marketable securities which have maturities beyond one year as of the end of the reporting period are classified as non-current.

The table below summarizes the Company’s cash, cash equivalents, restricted cash and short-term investments (in thousands):

There were no other-than-temporary impairments for these securities at September 30, 2022 or December 31, 2021. No gross realized gains or losses were recognized on the available-for-sale securities and, accordingly, there were no amounts reclassified out of accumulated other comprehensive income (loss) to earnings during the three and nine months ended September 30, 2022 and 2021.

As of September 30, 2022, and December 31, 2021, the contractual maturity of all investments held was less than one year.

Fair Value Measurement

The Company’s financial instruments consist of Level I and II assets and Level III liabilities. Money market funds are highly liquid investments and are actively traded. The pricing information on these investment instruments are readily available and can be independently validated as of the measurement date. This approach results in the classification of these securities as Level 1 of the fair value hierarchy. For Level II instruments, the Company estimates fair value by utilizing third party pricing services in developing fair value measurements where fair value is based on valuation methodologies such as models using observable market inputs, including benchmark yields, reported trades, broker/dealer quotes, bids, offers and other reference data. Such Level II instruments typically include U.S. treasury, U.S. government agency securities and commercial paper. As of September 30, 2022, and December 31, 2021, the Company held a contingent put option liability associated with the Loan Agreement with Oxford, determined to be a Level III instrument. The Company’s estimate of fair value of the contingent put option liability was determined by using a risk-neutral valuation model, wherein the fair value of the underlying debt facility is estimated both with and without the presence of the default provisions, holding all other assumptions constant. The resulting difference between the two estimated fair values is the estimated fair value of the default provisions, or the contingent put option. Changes to the estimated fair value of this liability is recorded in interest income and other income, net in the condensed consolidated statements of operations. The fair value of the underlying debt facility is estimated by calculating the expected cash flows in consideration of an estimated probability of default and expected recovery rate in default and discounting such cash flows back to the reporting date using a risk-free rate.

The following table sets forth the fair value of the Company’s financial assets and liabilities by level within the fair value hierarchy (in thousands):

The following tables set forth a summary of the changes in the fair value of the Company’s Level III financial liabilities for the three and nine months ended September 30, 2022 and 2021 (in thousands):

There were no transfers between Level I, Level II or Level III of the fair value hierarchy during the three and nine months ended September 30, 2022 and 2021.

3. Inventories, net

Inventories consist of raw materials, work in process and finished goods and are stated at the lower of cost or net realizable value and consist of the following (in thousands):

The Company did not record any inventory impairment charges for the three and nine months ended September 30, 2022. The Company recorded inventory impairment charges of $0.1 million and $0.2 million for the three and nine months ended September 30, 2021, respectively, primarily related to DSUVIA and Zalviso component parts inventory.

4. Asset Acquisition

On January 7, 2022, the Company closed its acquisition of Lowell and acquired the product nafamostat, and the associated patents and historical know-how. The acquisition was valued at approximately $32.5 million plus cash acquired of $3.5 million and certain other adjustments. All options to purchase capital stock and all shares of Lowell capital stock issued and outstanding immediately before the effective time of the merger were cancelled in exchange for the right to receive (i) 450,477 shares of AcelRx common stock issued at a five day daily volume weighted average price of $11.46 per share as of January 7, 2022, or the Acquisition Date, valued at $5.2 million on closing, (ii) cash in the amount of $3.5 million, (iii) 69,808 shares of AcelRx common stock to be held back to satisfy any potential indemnification and other obligations of Lowell and its securityholders valued at $0.8 million, (iv) $0.5 million cash and stock paid for sellers’ transaction costs and (v) up to $26.0 million of contingent consideration payable in cash or stock at AcelRx's option, upon the achievement of regulatory and sales-based milestones.

The shares issued in the merger were issued in a private placement pursuant to the exemption from registration under Section 4(a)(2) of the Securities Act of 1933, as amended, or the Securities Act, including Rule 506 of Regulation D promulgated under the Securities Act, or Regulation D, without general solicitation as a transaction not involving any public offering.

The merger has been accounted for as an asset acquisition of a single IPR&D asset that has an alternative future use. The initial measurement of the asset purchased of $8.8 million was based on the purchase cost of $12.4 million including (i) $6.0 million common stock fair value on the closing date (issued and held back on the acquisition date), (ii) $0.5 million seller’s costs paid by the Company, (iii) $3.5 million cash and (iv) approximately $2.5 million of transaction costs less purchase price allocated to cash acquired of $3.5 million. Due to the nature of regulatory and sales-based milestones, the contingent consideration of up to $26.0 million was not included in the initial cost of the assets purchased as they are contingent upon events that are outside the Company’s control, such as regulatory approvals and issuance of patents, and are not considered probable until notification is received. However, upon achievement or anticipated achievement of each milestone, the Company shall recognize the related, appropriate payment as an additional cost of the acquired IPR&D asset. As of September 30, 2022, none of the contingent events has occurred.

The following table summarizes the total consideration for the acquisition and the value of the IPR&D asset acquired (in thousands):

⁽¹⁾ Recorded as Other long-term liabilities in the condensed consolidated balance sheets.

⁽²⁾ Recorded as In-process research and development asset in the condensed consolidated balance sheets.

The IPR&D asset will be initially accounted for as an indefinite-lived asset, and as a long-lived asset, it will be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. If the IPR&D asset achieves regulatory approval and the asset life is determined to be finite, the asset’s useful life will be estimated, and the asset will be amortized over its remaining useful life. No impairment losses were recorded on the IPR&D asset during the three and nine months ended September 30, 2022.

5. Property and Equipment, Net

Property and equipment, net consist of the following (in thousands):

The Company has decided to realign its cost structure from a focus on commercialization to a focus on advancing its recently acquired late-stage development pipeline, namely the pre-filled syringes and Niyad product candidates. As a result, the Company has also decided to not focus any development resources on Zalviso in the United States, and does not expect to resubmit the Zalviso NDA in the foreseeable future. In addition, due to the termination of the agreements with Grünenthal for Zalviso in Europe and the related withdrawal of the Marketing Authorization in Europe in July 2022, the Company does not expect any revenues from Zalviso in Europe in the foreseeable future. Accordingly, the Company determined that it is no longer probable that it will realize the future economic benefit associated with the costs of the Zalviso-related purchased equipment and manufacturing-related facility improvements the Company has made at its contract manufacturer and, therefore, recorded a non-cash impairment charge of $4.9 million to the Zalviso-related assets for the nine months ended September 30, 2022. The impairment charge was recorded as operating expense in the condensed consolidated statement of operations. Depreciation and amortization expense was $0.2 million and $0.7 million for the three and nine months ended September 30, 2022, respectively, and $0.3 million and $0.8 million for the three and nine months ended September 30, 2021, respectively.

6. Revenue from Contracts with Customers

The following table summarizes revenue from contracts with customers for the three and nine months ended September 30, 2022 and 2021, into categories that depict how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors (in thousands):

For additional details on the Company’s accounting policy regarding revenue recognition, refer to Note 1 “Organization and Summary of Significant Accounting Policies - Revenue from Contracts with Customers” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021.

Product Sales

The Company’s commercial launch of DSUVIA in the United States occurred in the first quarter of 2019. Zalviso was sold in Europe by the Company’s collaboration partner, Grünenthal, through May 12, 2021, at which time, due to the termination of the Grünenthal Agreements, the rights to market and sell Zalviso in Europe reverted back to the Company. In July 2022, the European Marketing Authorization for Zalviso was withdrawn. DZUVEO sales in Europe by the Company’s collaboration partner, Aguettant, have recently commenced.

Contract and Other Collaboration

Contract and other collaboration revenue includes revenue under the Grünenthal Agreements related to research and development services, non-cash royalty revenue related to the Royalty Monetization and royalty revenue for sales of Zalviso in Europe and license revenue recognized under the DZUVEO Agreement. For the three and nine months ended September 30, 2022, the Company did not record any contract and other collaboration revenue.

Contract Liabilities

A contract liability of $1.2 million was recorded on the condensed consolidated balance sheets as deferred revenue as of September 30, 2022, $0.1 million of which represented the current portion, for the portion of the upfront fee received under the DZUVEO Agreement allocated to the material right for discounted price on future optional product supply which has not yet been satisfied. The material right contract liability will be recognized over the period the discount on future product supply is made available.

The following table presents changes in the Company’s contract liability for the nine months ended September 30, 2022 and 2021 (in thousands):

⁽¹⁾ Deferred revenue under the DZUVEO Agreement with Aguettant.

7. Long-Term Debt

Loan Agreement with Oxford

On May 30, 2019, the Company entered into the Loan Agreement with Oxford. Under the Loan Agreement, the Lender made a term loan to the Company in an aggregate principal amount of $25.0 million, or the Loan, which was funded on May 30, 2019. The Loan Agreement requires that the Company always maintain unrestricted cash of not less than $5.0 million in accounts subject to control agreements in favor of the Lender, tested monthly as of the last day of the month.

In connection with the Loan Agreement, on May 30, 2019, the Company issued warrants to the Lender and its affiliates, or the Warrants, which are exercisable for an aggregate of 8,833 shares of the Company’s common stock with a per share exercise price of $56.60. The Warrants have been classified within stockholders’ deficit and accounted for as a discount to the loan by allocating the gross proceeds on a relative fair value basis.

As of September 30, 2022 and December 31, 2021, the accrued balance due under the Loan Agreement with Oxford was $7.4 million and $13.3 million, respectively. Interest expense related to the Loan Agreement was $0.2 million, $0.1 million of which represented amortization of the debt discount, and $0.9 million, $0.3 million of which represented amortization of the debt discount, for the three and nine months ended September 30, 2022, respectively, while such interest expense was $0.5 million, $0.1 million of which represented amortization of the debt discount, and $1.7 million, $0.5 million of which represented amortization of the debt discount for the three and nine months ended September 30, 2021, respectively.

Non-Interest Bearing Payments for the Construction of Leasehold Improvements

In August 2019, the Company entered into a Site Readiness Agreement, or SRA, with Catalent Pharma Solutions, LLC, or Catalent, in contemplation of entering into a commercial supply agreement for its product DSUVIA at a future date. Under the SRA, the Company is building out a suite within Catalent’s production facility in Kansas City. If additional equipment and facility modifications are required to meet the Company’s product needs, the Company may be required to contribute to the cost of such additional equipment and facility modifications. The Company has determined that it is the owner of the leasehold improvements related to the build-out which are being paid in four annual installments of $0.5 million each. As of September 30, 2022 and December 31, 2021, the accrued balance under the SRA was $0.5 million, and $1.7 million of these leasehold improvements had been capitalized. The effective interest rate related to the payments at September 30, 2022 was 14%. The leasehold improvements are recorded as property and equipment, net, in the condensed consolidated balance sheets.

8. Leases

Office Lease

On March 26, 2021, the Company entered into a Sublease Agreement to sublet space for its new corporate headquarters. The Sublease Agreement commencement date was April 1, 2021. The Sublease Agreement is for a period of two years and three months with monthly rental payments of $17,000, including one month of abated rent.

9. Liability Related to Sale of Future Royalties

On September 18, 2015, the Company entered into the Royalty Monetization with PDL for which it received gross proceeds of $65.0 million. Under the Royalty Monetization, PDL was to receive 75% of the European royalties under the Amended License Agreement with Grünenthal, as well as 80% of the first four commercial milestones worth $35.6 million (or 80% of $44.5 million), up to a capped amount of $195.0 million over the life of the arrangement.

The Company periodically assessed the expected royalty and milestone payments using a combination of historical results, internal projections and forecasts from external sources. To the extent such payments were greater or less than the Company’s initial estimates or the timing of such payments is materially different than its original estimates, the Company prospectively adjusted the amortization of the liability and the effective interest rate. Grünenthal notified the Company that it was terminating the Amended License Agreement effective November 13, 2020. On August 31, 2020, PDL sold its royalty interest for Zalviso to SWK Funding, LLC, or SWK, under the Royalty Monetization. The terms of the Grünenthal Agreements were extended to May 12, 2021 to enable Grünenthal to sell down its Zalviso inventory. The rights to market and sell Zalviso in the Zalviso Territory reverted back to the Company on May 12, 2021.

On May 31, 2022, the Company entered into a Termination Agreement with SWK to fully terminate the Royalty Monetization for which the Company paid cash consideration of $0.1 million, and neither PDL nor SWK retains any further interest in the Royalty Monetization. Accordingly, effective May 31, 2022, the Royalty Monetization is no longer reflected on the Company’s consolidated financial statements or other records as a sale of assets to PDL or SWK and all security interests and other liens of every type held by the parties to the Royalty Monetization have been terminated and automatically released without further action by any party. The $84.1 million gain on extinguishment of the liability related to the sale of future royalties is recognized in the condensed consolidated statements of operations as other income.

The effective interest income rate for nine-month period ended September 30, 2022, was approximately 3.2%. The effective interest income rate for the nine-month period ended September 30, 2021, was approximately 3.6%.

The following table shows the activity within the liability account related to the sale of future royalties for the nine months ended September 30, 2022 and the period from inception on September 18, 2015 to September 30, 2022 (in thousands):

As mentioned above, the Royalty Monetization was terminated on May 31, 2022.

10. Commitments and Contingencies

Litigation

On June 8, 2021, a securities class action complaint was filed in the U.S. District Court for the Northern District of California against the Company and two of its officers. The plaintiff is a purported stockholder of the Company. The complaint alleges that defendants violated Sections 10(b) and 20(a) of the Exchange Act and SEC Rule 10b-5 by making false and misleading statements and omissions of material fact about the Company’s disclosure controls and procedures with respect to its marketing of DSUVIA. The complaint seeks unspecified damages, interest, attorneys’ fees, and other costs. On December 16, 2021, the Court appointed co-lead plaintiffs. Plaintiffs’ amended complaint was filed on March 7, 2022. The amended complaint names the Company and three of its officers and continues to allege that defendants violated Sections 10(b) and 20(a) of the Exchange Act and SEC Rule 10b-5 by making false and misleading statements and omissions of material fact about the Company’s disclosure controls and procedures with respect to its marketing of DSUVIA. The amended complaint also alleges a violation of Section 20A of the Exchange Act against the individual defendants for alleged insider trading. On September 1, 2022, the Court held oral hearings on the Company’s motion to dismiss the amended complaint with prejudice that was filed on July 21, 2022. On September 28, 2022, the Court issued a formal written opinion, or the Opinion, dismissing all of the plaintiff’s claims against the Company and the named defendants. Plaintiffs have been granted 60 days leave to amend their complaint and resubmit on or before November 28, 2022.

On July 6, 2021, a purported shareholder derivative complaint was filed in the U.S. District Court for the Northern District of California. The complaint names ten of the Company’s officers and directors and asserts state and federal claims based on the same alleged misstatements as the shareholder class action complaint. On September 30, 2021, October 26, 2021, and November 17, 2021, three additional purported shareholder derivative complaints were filed in the U.S. District Court for the Northern District of California. The complaints name nine of the Company’s officers and directors and also assert state and federal claims based on the same alleged misstatements as the shareholder class action complaint. All four complaints seek unspecified damages, attorneys’ fees, and other costs. On December 6, 2021, the Court entered an order consolidating all four actions and staying the consolidated action pending the outcome of any motion to dismiss the securities class action. Please see “Part II., Item 1A. Risk Factors—Risks of a General Nature—Litigation may substantially increase our costs and harm our business.”

The Company believes that these lawsuits are without merit and intends to vigorously defend against them. Given the uncertainty of litigation, the preliminary stage of the cases, and the legal standards that must be met for, among other things, class certification and success on the merits, the Company cannot estimate the reasonably possible loss or range of loss that may result from these actions.

11. Stockholders’ Equity

Preferred Stock

On August 3, 2022, the Company entered into a securities purchase agreement with Lincoln Park Capital Fund, LLC, or LPC or the Purchaser, pursuant to which the Company issued, in a private placement transaction, 3,000 shares of Series A Redeemable Convertible Preferred Stock, par value $0.001 per share, with $100 per share stated value, together with a warrant to purchase up to an aggregate of 81,150 shares of common stock at an exercise price of $4.07 per share (see Note 12 “Warrants”), for $0.3 million. The transaction price of $0.3 million was allocated to the Series A Redeemable Convertible Preferred Stock and warrants based on their relative fair values. The Series A Redeemable Convertible Preferred Stock was initially recorded at $0.1 million separately from stockholders’ equity in the Company’s condensed consolidated balance sheets due to the shares being redeemable based on based on contingent events outside of the Company’s control.

The Series A Redeemable Convertible Preferred Stock was convertible, at the option of the holders, into shares of common stock at a conversion price of approximately $3.70 per share, subject to adjustment and beneficial ownership limitations set forth in the Certificate of Designation. The Company had the option to redeem the Series A Redeemable Convertible Preferred Stock for cash at 105% of the Stated Value on the date of and for 15 days following the Reverse Stock Split, subject to the Purchaser’s right to convert the shares prior to such redemption. The Purchaser has the right to require the Company to redeem the shares of Series A Redeemable Convertible Preferred Stock for cash at 110% of the Stated Value of such shares commencing after the Company’s right to redeem expires. The Series A Redeemable Convertible Preferred Stock must be redeemed for cash at 110% of the Stated Value upon a delisting event. As a result, the Series A Redeemable Convertible Preferred Stock was recorded separately from stockholders’ equity because it was redeemable upon the occurrence of redemption events that were considered not solely withing the Company’s control. As such, during the three months ended September 30, 2022, the Company recognized approximately $0.2 million in deemed dividends related to the Series A Redeemable Convertible Preferred Stock in the condensed consolidated statements of operations and comprehensive loss and the condensed consolidated statements of changes in redeemable convertible preferred stock and stockholders’ equity (deficit).

As of September 30, 2022 the Company’s intent was to redeem the Series A Redeemable Convertible Preferred Stock at its election therefore, the Series A Redeemable Convertible Preferred Stock was remeasured to the expected redemption value of $0.3 million, with a “deemed dividend” of $0.2 million recorded and impacts earnings per share.

The holders of the Series A Redeemable Convertible Preferred Stock was entitled to certain registration rights, rights for approval of increases in the authorized shares of such series, and to dividends paid on common stock on an as-if converted basis. The Series A Redeemable Convertible Preferred stock had no voting rights, other than the right to (i) vote exclusively on the Reverse Stock Split and any proposal to adjourn any meeting of stockholders called for the purpose of voting on the Reverse Stock Split and (ii) to 1,000,000 votes per each share of Series A Redeemable Convertible Preferred Stock, to vote together with the common stock, as a single class; to the extent cast on the Reverse Stock Split in the same proportion as shares of common stock. In addition, in the event of any liquidation, dissolution, or winding-up of the Company, the holders of the Series A Redeemable Convertible Preferred Stock are entitled to receive 110% the preferred stock’s Stated Value plus any declared but unpaid dividends before any payment is made to holders of common stock.

On October 11, 2022, the Company and LPC entered into the Securities Redemption Agreement whereby on October 12, 2022, the Company redeemed for cash at a price equal to 105% of the Stated Value per share all 3,000 outstanding shares of Series A Redeemable Convertible Preferred Stock for $0.3 million. As a result, all shares of such series were retired and are no longer outstanding. On October 25, 2022, the Company filed a certificate of elimination to its amended and restated certificate of incorporation which (i) eliminated the previous designation of 3,000 shares of Series A Redeemable Convertible Preferred Stock from the Company’s amended and restated certificate of incorporation and (ii) caused such shares of Series A Redeemable Convertible Preferred Stock to resume their status as authorized but unissued and non-designated shares of preferred stock.

14. Net Income (Loss) per Share of Common Stock

The Company’s basic net income (loss) per share of common stock is calculated by dividing the net income (loss) allocable to common shareholders by the weighted average number of shares of common stock outstanding for the period. The diluted net income (loss) per share of common stock is computed by giving effect to all potential common stock equivalents outstanding for the period determined using the more dilutive of the 1) treasury stock method, if-converted method, or contingently issuable share method, as applicable, or 2) the two-class method. For purposes of this calculation, options to purchase common stock, RSUs, and warrants to purchase common stock were considered to be common stock equivalents. In periods with a reported net loss, common stock equivalents are excluded from the calculation of diluted net loss per share of common stock if their effect is antidilutive.

The following table sets forth the computation of the Company’s basic and diluted net income (loss) per share of common stock during the three and nine months ended September 30, 2022 and 2021 (in thousands, except for share and per share amounts):
