ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

The following discussion and analysis of our financial condition and results of operations should be read together with our audited financial statements and the related notes and other financial information included elsewhere in this Annual Report on Form 10-K. Some of the information contained in this discussion and analysis or set forth elsewhere in this Annual Report on Form 10-K, including information with respect to our plans and strategy for our business, include forward-looking statements that involve risks and uncertainties. You should review the “Risk Factors” included in Item 1A of this Annual Report on Form 10-K for a discussion of important factors that could cause our actual results to differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis.

Introduction

Management’s discussion and analysis of financial condition and results of operations is provided as a supplement to the Consolidated Financial Statements and Notes, included in Item 8 of this Annual Report on Form 10-K, to help provide an understanding of our financial condition, the changes in our financial condition and our results of operations. Our discussion is organized as follows:

Overview. This section provides a general description of our business and operating expenses.

Critical accounting policies and estimates. This section contains a discussion of the accounting policies that we believe are important to our financial condition and results of operations and that require significant judgment and estimates on the part of management in their application. In addition, all of our significant accounting policies, including the critical accounting policies and estimates, are summarized in Note 2 to the Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K.

Results of operations. This section provides an analysis of our results of operations presented in the accompanying consolidated statements of operations and comprehensive loss by comparing the results for the year ended December 31, 2022 to the results for the year ended December 31, 2021.

Liquidity and capital resources. This section provides an analysis of our cash flows and a discussion of our outstanding commitments and contingencies that existed as of December 31, 2022. Included in this discussion is our financial capacity to fund our future commitments and a discussion of other financing arrangements.

Overview

We are a commercial-stage biotechnology company focused on improving the lives of patients by developing and commercializing therapeutic innovations that improve medical care. Our advanced science, patented technologies, and innovative approach to drug discovery and development have allowed us to create and commercialize a portfolio of products that aim to advance the standard of care for acute care and oncology patients.

CINVANTI® (aprepitant) injectable emulsion (“CINVANTI”) and SUSTOL® (granisetron) extended-release injection (“SUSTOL”) are both approved in the United States (“U.S.”) for the prevention of chemotherapy-induced nausea and vomiting. ZYNRELEF® (bupivacaine and meloxicam) extended-release solution (“ZYNRELEF”) is approved in the U.S., 31 European countries and Canada for the management of postoperative pain.

In September 2022, APONVIETM (aprepitant) injectable emulsion (“APONVIE”) was approved in the U.S. for the prevention of postoperative nausea and vomiting and became commercially available in the U.S. in March 2023. We are also developing HTX-034, an investigational agent, our next generation product candidate for the management of postoperative pain.

64

Net Product Sales

Net product sales include revenue recognized for sales of CINVANTI, SUSTOL and ZYNRELEF (collectively, our “Products”) to a limited number of specialty distributors and full line wholesalers (collectively, “Customers”), less applicable sales allowances. See the “Critical Accounting Policies and Estimates” section of this Annual Report on Form 10-K for further details on our revenue recognition policy.

Cost of Product Sales

Cost of product sales relates to the costs to produce, package and deliver our Products to our Customers. These costs include raw materials, labor, manufacturing and quality control overhead, and depreciation of equipment, as well as shipping and distribution costs. We expect cost of product sales to decrease in 2023, as large-scale manufacturing of ZYNRELEF and CINVANTI were validated in the fourth quarter of 2022. See the “Critical Accounting Policies and Estimates” section of this Annual Report on Form 10-K for further details on our inventory policy.

Research and Development Expense

All costs of research and development are expensed in the period incurred. Research and development expense primarily consists of salaries, stock-based compensation expense and other related costs for personnel in manufacturing, clinical and preclinical development, regulatory, quality and medical affairs. Other research and development expense includes professional fees paid to outside service providers and consultants, facilities costs and materials used in the clinical and preclinical trials and research and development.

At this time, due to the risks inherent in the clinical trial process, we are unable to estimate with any certainty the costs we will incur in the continued development of our product candidates. Other than costs for outsourced services associated with our clinical programs, we generally do not track research and development expense by project; rather, we track such expense by the type of cost incurred.

We expect research and development expense to decrease in 2023 because (i) APONVIE was approved in September 2022, (ii) we received U.S. Food and Drug Administration (“FDA”) approval for two manufacturing supplements to the New Drug Application (“NDA”) for ZYNRELEF to add a large-scale supplier of our proprietary polymer and to add larger-scale manufacturing of ZYNRELEF, (iii) larger-scale manufacturing of CINVANTI was validated in the fourth quarter of 2022, and (iv) we submitted a supplemental NDA for ZYNRELEF to further expand the indication statement in December 2022.

General and Administrative Expense

General and administrative expense primarily consists of salaries, stock-based compensation expense and other related costs for personnel in executive, finance and accounting, information technology, legal and human resource functions. Other general and administrative expense includes professional fees for legal, investor relations, accounting and other general corporate purposes, facility costs and insurance not otherwise included in research and development expense. We expect general and administrative expense in 2023 to remain comparable with 2022.

Sales and Marketing Expense

Sales and marketing expense primarily consists of salaries and related costs for personnel, stock-based compensation expense and other related costs for sales operations, marketing and market access. Other sales and marketing costs include professional fees and commercialization costs related to launch activities for ZYNRELEF, ongoing costs related to CINVANTI and SUSTOL, and launch preparation activities for APONVIE. We expect sales and marketing expense to decrease in 2023, as 2022 included one-time launch preparation costs for ZYNRELEF and the APONVIE launch will leverage our existing commercial organization in the acute care setting, with no additional field force and limited external spend.

65

Other Expense, Net

Other expense, net primarily consists of interest expense and the amortization of debt issuance costs related to our convertible notes payable, write-off of property and equipment, and income earned on our cash, cash equivalents and short-term investments.

Critical Accounting Policies and Estimates

A summary of the significant accounting policies is provided in Note 2 to our Consolidated Financial Statements.

The discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the U.S. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. We evaluate our estimates on an ongoing basis, including those related to revenue recognition, investments, inventory, accrued clinical liabilities, income taxes and stock-based compensation. We base our estimates on historical experience and on assumptions that we believe to be reasonable under the circumstances, the results of which form the basis of making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ materially from these estimates under different assumptions or conditions.

Management considers an accounting estimate to be critical if: it requires a significant level of estimation uncertainty, and changes in the estimate are reasonably likely to have a material effect on our financial condition or results of operations.

We believe the following critical accounting policies and estimates describe the most significant judgments and estimates used in the preparation of our consolidated financial statements.

Revenue Recognition

Product Sales

Our Products are distributed in the U.S. through a limited number of Customers that resell to healthcare providers and hospitals, the end users of our Products.

Revenue is recognized in an amount that reflects the consideration we expect to receive in exchange for our Products. To determine revenue recognition for contracts with customers, we perform the following 5 steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations of the contract(s); (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract(s); and (v) recognize revenue when (or as) we satisfy the performance obligations.

66

Product Sales Allowances

We recognize product sales allowances as a reduction of product sales in the same period the related revenue is recognized. Product sales allowances are based on amounts owed or to be claimed on the related sales. Such variable consideration includes estimates that take into consideration the terms of our agreements with Customers, historical product returns, rebates or discounts taken, the shelf life of the product and specific known market events, such as competitive pricing and new product introductions. If actual future results vary from our estimates, we may need to adjust these estimates, which could have an effect on product sales and earnings in the period of adjustment.

We believe our estimated allowances for distributor fees, group purchasing organization discounts, rebates and administrative fees and Medicaid rebates do not require a high degree of judgment because the amounts are settled within a relatively short period of time.

We believe our estimated allowance for product returns requires a high degree of judgment and is subject to change based on our experience and certain quantitative and qualitative factors. We allow our Customers to return product for credit for up to 12 months after its product expiration date. As such, there may be a significant period of time between the time the product is shipped and the time the credit is issued on returned product. We regularly monitor our estimates and record adjustments when return trends, contract terms or other significant events indicate that a change in estimates is appropriate. To date, our estimates have not differed materially from actual returns. However, subsequent changes in estimates may result in a material change to our product sales allowances, which could materially affect our results of operations and financial position.

Investments

We invest in various types of securities, including U.S. treasury bills and government agency obligations, corporate debt securities and commercial paper. These securities have been initially valued at the transaction price and subsequently valued utilizing a third-party service provider who assesses the fair value using inputs other than quoted prices that are observable either directly or indirectly, such as yield curve, volatility factors, credit spreads, default rates, loss severity, current market and contractual prices for the underlying instruments or debt, broker and dealer quotes, as well as other relevant economic measures. We perform certain procedures to corroborate the fair value of these holdings, and in the process, we apply judgment and estimates that if changed, could significantly affect our statements of financial positions. To date, our estimates have not differed materially from actual values. However, subsequent changes in estimates may result in a material change to the value of our cash equivalents and short-term investments, which could materially affect our results of operations and financial position.

Inventory

Inventory is stated at the lower of cost or estimated net realizable value on a first-in, first-out, or FIFO, basis. We periodically analyze our inventory levels and write down inventory that has become obsolete, inventory that has a cost basis in excess of its estimated realizable value and inventory quantities that are in excess of expected sales requirements as cost of product sales. The determination of whether inventory costs will be realizable requires estimates by management. If actual market conditions are less favorable than projected by management, additional write-downs of inventory may be required. Cost of product sales for the year ended December 31, 2022 included charges of $8.9 million, resulting primarily from the write-off of short-dated ZYNRELEF inventory. In addition, cost of product sales for the year ended December 31, 2021 included charges of $3.8 million, resulting from the write-off of short-dated SUSTOL inventory.

67

Accrued Research and Development Expenses

We estimate certain costs and expenses and accrue for these liabilities as part of our process of preparing financial statements. Examples of areas in which subjective judgment may be required include, among other things, costs associated with services provided by contract organizations for preclinical and clinical development, and manufacturing of our Products and product candidates. We accrue for costs incurred as the services are being provided by monitoring the status of the services provided, and the invoices received from our external service providers. In the case of clinical trials, we rely on estimates of the progress of the clinical trials and related expenses incurred. Changes to estimates are recorded to research and development expense in the period in which the facts that gave rise to the revision become known. To date, our estimates have not differed materially from the actual costs incurred. However, subsequent changes in estimates may result in a material change to our accruals, which could also materially affect our results of operations and financial position.

Income Taxes

We make certain estimates and judgments in determining income tax expense for financial statement purposes. These estimates and judgments occur in the calculation of certain deferred tax assets and liabilities, which arise from differences in the timing of recognition of revenue and expense for tax and financial statement purposes. As part of the process of preparing our consolidated financial statements, we are required to estimate our income taxes for each of the jurisdictions in which we operate. This process involves estimating our current tax exposure under the most recent tax laws and assessing temporary differences resulting from differing treatment of items for tax and financial statement purposes. At December 31, 2022, we established a valuation allowance to offset our deferred tax assets due to the uncertainty of realizing future tax benefits from our net operating loss carryforwards and other deferred tax assets. To date, our estimates have not materially changed. However, subsequent changes in estimates may result in a significant change to our deferred tax assets and liabilities, which could materially affect our results of operations and financial position.

Stock-based Compensation

We estimate the fair value of stock options granted using the Black-Scholes option pricing model. This fair value is then amortized over the requisite service periods of the awards. The Black-Scholes option pricing model requires the input of subjective assumptions, including each option’s expected life and price volatility of the underlying stock. Expected volatility is based on our historical stock price volatility. The expected life of employee stock options represents the average of the contractual term of the options and the weighted-average vesting period, as permitted under the simplified method. To date, our assumptions used in our calculation of stock-based compensation expense has not significantly changed. However, subsequent changes in our assumptions could impact our stock-based compensation expense, which could materially affect our net loss and net loss per share.

Results of Operations

Years Ended December 31, 2022 and 2021

Net Product Sales

For the year ended December 31, 2022, net product sales were $107.7 million, compared to $86.3 million for the same period in 2021.

Net Product Sales – Oncology Care

For the year ended December 31, 2022, net product sales of CINVANTI were $87.3 million, compared to $73.5 million for the same period in 2021. For the year ended December 31, 2022, net product sales of SUSTOL were $10.2 million, compared to $9.9 million for the same period in 2021.

Net Product Sales – Acute Care

For the year ended December 31, 2022, net product sales of ZYNRELEF were $10.2 million, which was net of $0.5 million in returns for short-dated product. Short-dated product returns were due to delays in obtaining initial FDA approval of ZYNRELEF. For the year ended December 31, 2021, net product sales of ZYNRELEF were $2.9 million, which was net of $45,000 in returns for short-dated product. We commenced commercial sales of ZYNRELEF in the U.S. in July 2021.

Cost of Product Sales

For the year ended December 31, 2022, cost of product sales was $54.9 million, compared to $46.0 million for the same period in 2021. Cost of product sales primarily included raw materials, labor and overhead related to the manufacturing of our Products, as well as shipping and distribution costs. For the year ended December 31, 2022, cost of product sales also included charges of $8.9 million, resulting primarily from the write-off of short-dated ZYNRELEF inventory. For the year ended December 31, 2021, cost of product sales also included charges of $3.8 million, resulting from the write-off of short-dated SUSTOL inventory.

Prior to FDA approval, $23.6 million of costs to manufacture ZYNRELEF were recorded to research and development expense in prior periods. We began capitalizing raw materials, labor and overhead related to the manufacturing of ZYNRELEF following FDA approval in May 2021.

We began capitalizing raw materials, labor and overhead related to the manufacturing of APONVIE following FDA approval in September 2022. There were no costs incurred prior to FDA approval for the commercial manufacturing of APONVIE.

Research and Development Expense

Research and development expense consisted of the following (in thousands):

December 31,

For the year ended December 31, 2022, research and development expense was $107.5 million, compared to $130.8 million for the same period in 2021. This decrease was primarily due to decreases in personnel and related costs of $11.5 million, as well as decreases in costs related to APONVIE, CINVANTI and HTX-034 of $5.3 million, $3.1 million and $2.5 million, respectively.

69

General and Administrative Expense

For the year ended December 31, 2022, general and administrative expense was $37.4 million, compared to $40.2 million for the same period in 2021. This decrease was primarily due to a reduction in facility-related costs as we subleased a portion of our leased space beginning in March 2022.

Sales and Marketing Expense

For the year ended December 31, 2022, sales and marketing expense was $82.5 million, compared to $87.2 million for the same period in 2021. This decrease was primarily due to a decrease in costs to support the ongoing commercialization of CINVANTI and SUSTOL, partially offset by an increase in costs to support the launch activities for ZYNRELEF.

Other Expense, Net

For the year ended December 31, 2022, other expense, net was $7.4 million, compared to $2.9 million for the same period in 2021. The increase was primarily due to the write-off of property and equipment at a third-party manufacturing site, partially offset by an increase in interest income earned on our short-term investments.

Restructuring Plans

See Note 7 to the Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K for discussion of the restructuring plans implemented in October 2021 and June 2022.

Liquidity and Capital Resources

We have incurred significant operating losses and negative cash flows from operations. As of December 31, 2022, we had an accumulated deficit of $1.8 billion and cash, cash equivalents and short-term investments of $84.9 million. In addition, our net loss for the year ended December 31, 2022 was $182.0 million. These factors raise substantial doubt regarding our ability to continue as a going concern for a period of one year after the date that the financial statements are issued, however, based on our current operating plan and projections, management believes that the Company’s existing cash, cash equivalents and short-term investments will be sufficient to meet the Company’s anticipated cash requirements for at least one year from the date this Annual Report on Form 10-K is filed with the U.S. Securities and Exchange Commission.

In order to meet our cash requirements, we may be required to obtain additional funds and if we are not able to obtain adequate funds, we may be required to delay, reduce the scope of, or eliminate activities to support our Products and reduce personnel and related costs, which could have a material adverse effect on our business.

Our capital requirements and liquidity for the next twelve months will depend on numerous factors, including but not limited to: the degree of commercial success of our Products; the impact of competitive products; the timing and cost to manufacture our Products; the costs associated with the U.S. commercial launch of ZYNRELEF and APONVIE; the time, cost and outcome involved in seeking a further expanded label for ZYNRELEF in the U.S.; our ability to establish and maintain strategic collaborations or partnerships for research, development, clinical testing, manufacturing and marketing of our Products and product candidates; and general market conditions. Management’s view of our liquidity relies on estimates and assumptions about the market opportunity for the expanded U.S. label of ZYNRELEF, which estimates and assumptions are subject to significant uncertainty.

We may not be able to raise sufficient additional capital when needed on favorable terms, or at all. If we are unable to obtain adequate funds, we may be required to curtail significantly or cease our operations. If we issue additional equity securities or securities convertible into equity securities to raise funds, our stockholders will suffer dilution of their investment, and such issuance may adversely affect the market price of our common stock.

70

Any new debt financing we enter into may involve covenants that restrict our operations. These restrictive covenants may include, among other things, limitations on borrowing and specific restrictions on the use of our assets, as well as prohibitions on our ability to create liens, pay dividends, redeem capital stock or make investments. In the event that additional funds are obtained through arrangements with collaborative partners, these arrangements may require us to relinquish rights to some of our technologies, product candidates or Products on terms that are not favorable to us or require us to enter into a collaboration arrangement that we would otherwise seek to develop and commercialize ourselves. If adequate funds are not available, we may default on our indebtedness, which could have a material adverse effect on our business.

Our net loss for the year ended December 31, 2022 was $182.0 million, or $1.67 per share, compared to a net loss of $220.7 million, or $2.24 per share for the same period in 2021.

Our net cash used in operating activities for the year ended December 31, 2022 was $146.9 million, compared to $203.4 million for the same period in 2021. The decrease in net cash used in operating activities was primarily due to changes in working capital, as well as a decrease in net loss.

Our net cash used for investing activities for the year ended December 31, 2022 was $3.3 million, compared to net cash provided by investing activities of $32.7 million for the same period in 2021. The decrease in cash provided by investing activities was primarily due to net purchases of short-term investments of $1.7 million for the year ended December 31, 2022, compared to net maturities of $35.7 million for the same period in 2021.

Our net cash provided by financing activities for the year ended December 31, 2022 was $75.1 million, compared to $156.0 million for the same period in 2021. The decrease in cash provided by financing activities was primarily due to net proceeds of $149.0 million from a convertible note financing received in May 2021, partially offset by net proceeds of $75.1 million received from a private placement in August 2022.

Historically, we have financed our operations, including technology and product research and development, primarily through sales of our common stock and debt financings.

Material Cash Requirements

As of December 31, 2022, we had an operating lease for 52,148 square feet of laboratory and office space in San Diego, California, with a lease term that expires on December 31, 2025. In October 2021, we entered into a sublease agreement to sublet 23,873 square feet of laboratory and office space. The space was delivered to the subtenant in March 2022. The sublease agreement expires on December 31, 2025 and is coterminous with the operating lease for the subleased space. As of December 31, 2022, we had total operating lease obligations of $9.1 million, with $3.0 million due in one year and $6.1 million due within two to three years.

At December 31, 2022, capital expenditures consisted of non-cancellable commitments for equipment at our third-party manufacturers. Total capital expenditures of $0.7 million were not included in our consolidated financial statements for the year ended December 31, 2022 and are due within one year. We intend to use our current financial resources to fund our commitments under the capital expenditure obligations.

At December 31, 2022, purchase obligations primarily consisted of non-cancellable commitments with third-party manufacturers in connection with the manufacturing of our Products. Total purchase obligations of $103.7 million were not included in our consolidated financial statements for the year ended December 31, 2022, with $38.7 million due in one year and $65.0 million due within two to three years. We intend to use our current financial resources to fund our commitments under these purchase obligations.

71

As of December 31, 2022, $150.0 million aggregate principal amount of the convertible notes were outstanding (see Note 8 to the Consolidated Financial Statements included in this Annual Report on Form 10-K). The convertible notes mature on May 26, 2026, unless earlier converted, redeemed or repurchased.

We enter into agreements with clinical sites and clinical research organizations for the conduct of our clinical trials and contract manufacturing organizations for the manufacture and supply of preclinical, clinical and commercial materials and drug product. We make payments to these clinical sites and clinical research organizations based in part on the number of eligible patients enrolled and the length of their participation in the clinical trials. In some of our agreements with contract manufacturing organizations, we are required to meet minimum purchase obligations. Under certain of these agreements, we may be subject to penalties in the event that we prematurely terminate these agreements. At this time, due to the variability associated with clinical site agreements, contract research organization agreements and contract manufacturing agreements, we are unable to estimate with certainty the future costs we will incur. We intend to use our current financial resources to fund our obligations under these commitments.

REport of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors

Heron Therapeutics, Inc.

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Heron Therapeutics, Inc. and subsidiaries (the “Company”) as of December 31, 2022 and 2021, and the related consolidated statements of operations and comprehensive loss, stockholders’ equity, and cash flows for each of the two years in the period ended December 31, 2022, and the related notes (collectively referred to as the “consolidated financial statements”).

In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2022, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the entity’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements; and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

74

Allowance for Product Returns

Description of the Matter

As discussed in Note 5 to the consolidated financial statements, the Company earns its revenue through the sale of its products, CINVANTI, SUSTOL and ZYNRELEF, to specialty distributors. Such revenue totaled $107.7 million for the year ended December 31, 2022. The amount of revenue recognized is net of product sales allowances for product returns, distributor fees, group purchase organization fees, discounts and rebates, and Medicare rebates, which totaled $181.1 million for the year ended December 31, 2022. The allowances are recorded in the same period that the related revenue is recognized and create variability in the consideration that the Company expects to receive. Management’s estimated allowance for product returns requires a high degree of judgment and is subject to change based on various quantitative and qualitative factors. Accordingly, extensive audit effort and a high degree of auditor judgment were needed to evaluate management’s estimates and assumptions used in the determination of product returns. Therefore, we identified management's allowance for product returns as a critical audit matter.

How We Addressed the Matter in Our Audit

We tested the effectiveness of internal control over financial reporting that relate to the Company’s processes for estimating product returns.

We evaluated the significant accounting policies relating to product returns, as well as management’s application of the policies, for appropriateness and reasonableness.

We selected a sample of customer transactions and performed the following procedures for each selection:

Obtained and read contract source documents and management’s contract analyses.

Evaluated whether the selected estimates were applied consistently across similar arrangements.

Tested the reasonableness of management’s assumptions by comparing them to historical data, peer group information, and, where available, subsequent product returns.

Where management used actual shipments and returns to estimate product returns, we tested the third-party reports used by management for completeness and accuracy.

Additionally, we tested the mathematical accuracy of management’s calculation of revenue, net of product sales allowances, including product returns, and the associated timing of revenue recognition, in the consolidated financial statements.

Assessment of the Company’s Ability to Continue as a Going Concern

Description of the Matter

As discussed in Note 1 to the consolidated financial statements, such financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The Company has identified conditions that raise substantial doubt about its ability to continue as a going concern and has concluded that such substantial doubt is alleviated as a result of consideration of their plans.

We identified management’s assessment of their ability to continue as a going concern as a critical audit matter. Significant auditor judgment was required to evaluate certain key assumptions regarding the cash flow projections, including revenue projections, operating expense projections, and the timing of cash flows.

75

How We Addressed the Matter in Our Audit

The primary procedures we performed to address this critical audit matter included:

obtaining an understanding of the Company's process for determining their ability to continue as a going concern, which included management's analysis over the inputs and assumptions used to forecast future cash flows in the going concern analysis,

evaluating the significant assumptions used in developing the financial projections,

evaluating the sensitivity to change of assumptions used, including revenue projections and operating expense projections, and

assessing management’s financial projections in the context of other audit evidence obtained during the audit and historical performance to determine whether it was contradictory to the conclusion reached by management.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Organization and Business

We are a commercial-stage biotechnology company focused on improving the lives of patients by developing and commercializing therapeutic innovations that improve medical care. Our advanced science, patented technologies, and innovative approach to drug discovery and development have allowed us to create and commercialize a portfolio of products that aim to advance the standard of care for acute care and oncology patients.

CINVANTI® (aprepitant) injectable emulsion (“CINVANTI”) and SUSTOL® (granisetron) extended-release injection (“SUSTOL”) are both approved in the United States (“U.S.”) for the prevention of chemotherapy-induced nausea and vomiting. ZYNRELEF® (bupivacaine and meloxicam) extended-release solution (“ZYNRELEF”) is approved in the U.S., 31 European countries and Canada for the management of postoperative pain.

In September 2022, APONVIETM (aprepitant) injectable emulsion (“APONVIE”) was approved in the U.S. for the prevention of postoperative nausea and vomiting and became commercially available in the U.S. in March 2023. We are also developing HTX-034, an investigational agent, our next-generation product candidate for the management of postoperative pain.

In accordance with Accounting Standards Codification (“ASC”) 205-40, Going Concern, we evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about our ability to continue as a going concern within one year after the date that the consolidated financial statements are issued. This evaluation initially does not take into consideration the potential mitigating effect of our plans that have not been fully implemented as of the date the financial statements are issued. When substantial doubt exists under this methodology, we evaluate whether the mitigating effect of its plans sufficiently alleviates substantial doubt about our ability to continue as a going concern. The mitigating effect of our plans, however, is only considered if both (1) it is probable that the plans will be effectively implemented within one year after the date that the financial statements are issued, and (2) it is probable that the plans, when implemented, will mitigate the relevant conditions or events that raise substantial doubt about our ability to continue as a going concern within one year after the date that the financial statements are issued.

We have incurred significant operating losses and negative cash flows from operations. As of December 31, 2022, we had an accumulated deficit of $1.8 billion and cash, cash equivalents and short-term investments of $84.9 million. In addition, our net loss for the year ended December 31, 2022 was $182.0 million. These factors raise substantial doubt regarding our ability to continue as a going concern for a period of one year after the date that the financial statements are issued, however, based on our current operating plan and projections, management believes that the Company’s existing cash, cash equivalents and short-term investments will be sufficient to meet the Company’s anticipated cash requirements for at least one year from the date this Annual Report on Form 10-K is filed with the U.S. Securities and Exchange Commission (“SEC”).

In order to meet our cash requirements, we may be required to obtain additional funds and if we are not able to obtain adequate funds, we may be required to delay, reduce the scope of, or eliminate activities to support our Products and reduce personnel and related costs, which could have a material adverse effect on our business.

Our capital requirements and liquidity for the next twelve months will depend on numerous factors, including but not limited to: the degree of commercial success of our Products; the impact of competitive products; the timing and cost to manufacture our Products; the costs associated with the U.S. commercial launch of ZYNRELEF and APONVIE; the time, cost and outcome involved in seeking a further expanded label for ZYNRELEF in the U.S.; our ability to establish and maintain strategic collaborations or partnerships for research, development, clinical testing, manufacturing and marketing of our Products and product candidates; and general market conditions. Management’s view of our liquidity relies on estimates and assumptions about the market opportunity for the expanded U.S. label of ZYNRELEF, which estimates and assumptions are subject to significant uncertainty.

We may not be able to raise sufficient additional capital when needed on favorable terms, or at all. If we are unable to obtain adequate funds, we may be required to curtail significantly or cease our operations. If we issue

81

additional equity securities or securities convertible into equity securities to raise funds, our stockholders will suffer dilution of their investment, and such issuance may adversely affect the market price of our common stock.

Any new debt financing we enter into may involve covenants that restrict our operations. These restrictive covenants may include, among other things, limitations on borrowing and specific restrictions on the use of our assets, as well as prohibitions on our ability to create liens, pay dividends, redeem capital stock or make investments. In the event that additional funds are obtained through arrangements with collaborative partners, these arrangements may require us to relinquish rights to some of our technologies, product candidates or Products on terms that are not favorable to us or require us to enter into a collaboration arrangement that we would otherwise seek to develop and commercialize ourselves. If adequate funds are not available, we may default on our indebtedness, which could have a material adverse effect on our business.

Summary of Significant Accounting Policies

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of Heron Therapeutics, Inc. and its wholly-owned subsidiary, Heron Therapeutics B.V., which was organized in the Netherlands in March 2015. Heron Therapeutics B.V. has no operations and no material assets or liabilities, and there have been no significant transactions related to Heron Therapeutics B.V. since its inception.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and disclosures made in the accompanying notes to the financial statements. Our significant accounting policies that involve significant judgment and estimates include revenue recognition, investments, inventory and the related reserves, accrued clinical liabilities, income taxes and stock-based compensation. Actual results could differ materially from those estimates.

Cash, Cash Equivalents and Short-term Investments

Cash and cash equivalents consist of cash and highly liquid investments with contractual maturities of three months or less from the original purchase date.

Short-term investments consist of securities with contractual maturities of greater than three months from the original purchase date. Securities with contractual maturities greater than one year are classified as short-term investments on the consolidated balance sheets, as we have the ability, if necessary, to liquidate these securities to meet our liquidity needs in the next 12 months. We have classified our short-term investments as available-for-sale securities in the accompanying consolidated financial statements. Available-for-sale securities are stated at fair market value, with net changes in unrealized gains and losses reported in other comprehensive loss and realized gains and losses included in other expense, net. The cost of securities sold is based on the specific identification method. Interest and dividends on securities classified as available-for-sale are included in interest income.

Fair Value of Financial Instruments

A company may elect to use fair value to measure accounts and loans receivable, available-for-sale and held-to-maturity securities, equity method investments, accounts payable, guarantees and issued debt. Other eligible items include firm commitments for financial instruments that otherwise would not be recognized at inception and non-cash warranty obligations where a warrantor is permitted to pay a third party to provide the warranty goods or services. If the use of fair value is elected, any upfront costs and fees related to the item such as debt issuance costs must be recognized in earnings and cannot be deferred. The fair value election is irrevocable and generally made on an instrument-by-instrument basis, even if a company has similar instruments that it elects not to measure based on fair value. Unrealized gains and losses on existing items for which fair value has been elected are reported as a cumulative adjustment to beginning retained earnings and any changes in fair value are recognized in earnings. We have elected to not apply the fair value option to our financial assets and liabilities.

82

Financial instruments, including cash and cash equivalents, receivables, inventory, prepaid expenses, other current assets, accounts payable and accrued expenses, are carried at cost, which is considered to be representative of their respective fair values because of the short-term maturity of these instruments. Short-term available-for-sale investments are carried at fair value (see Note 3). Our convertible notes outstanding at December 31, 2022 and 2021 do not have a readily available ascertainable market value, however, the carrying value is considered to approximate its fair value.

Concentration of Credit Risk

Cash, cash equivalents and short-term investments are financial instruments that potentially subject us to concentrations of credit risk. We deposit our cash in financial institutions. At times, such deposits may be in excess of insured limits. We have not experienced any losses in such accounts and believe we are not exposed to significant risk on our cash, cash equivalents and short-term investments.

We may also invest our excess cash in money market funds, U.S. government and agencies, corporate debt securities and commercial paper. We have established guidelines relative to our diversification of our cash investments and their maturities in an effort to maintain safety and liquidity. These guidelines are periodically reviewed and modified to take advantage of trends in yields and interest rates.

CINVANTI, SUSTOL and ZYNRELEF (collectively, our “Products”) are distributed in the U.S. through a limited number of specialty distributors and full line wholesalers (collectively, “Customers”) that resell to healthcare providers and hospitals, the end users of our Products.

The following table includes the percentage of net product sales and accounts receivable balances for our three major Customers, each of which comprised 10% or more of our net product sales:

Net ProductSales AccountsReceivable

83

Accounts Receivable, Net

Accounts receivable are recorded at the invoice amount, net of an allowance for credit losses. The allowance for credit losses reflects accounts receivable balances that are believed to be uncollectible. In estimating the allowance for credit losses, we consider: (1) our historical experience with collections and write-offs; (2) the credit quality of our Customers and any recent or anticipated changes thereto; (3) the outstanding balances and past due amounts from our Customers; and (4) reasonable and supportable forecast of economic conditions expected to exist throughout the contractual term of the receivable.

We offered extended payment terms to our Customers in connection with our product launch of ZYNRELEF in July 2021. In addition, we offered extended payment terms to our Customers in January 2021 when we reinstated the promotion and contracting of SUSTOL. These extended payment terms were offered in anticipation of the timing of reimbursement by government and commercial payers. Effective October 2021, we shortened payment terms to our ZYNRELEF and SUSTOL Customers.

As of December 31, 2022 and 2021, we determined that an allowance for doubtful accounts was not required. For the years ended December 31, 2022 and 2021, we did not have any material write-offs any accounts receivable balances.

Inventory

Inventory is stated at the lower of cost or estimated net realizable value on a first-in, first-out, or FIFO, basis. We periodically analyze our inventory levels and write down inventory that has become obsolete, inventory that has a cost basis in excess of its estimated realizable value and inventory quantities that are in excess of expected sales requirements as cost of product sales. The determination of whether inventory costs will be realizable requires estimates by management. If actual market conditions are less favorable than projected by management, additional write-downs of inventory may be required, which would be recorded as cost of product sales.

Property and Equipment

Property and equipment is stated at cost less accumulated depreciation and amortization. Depreciation is calculated on a straight-line basis over the estimated useful lives of the assets (generally 5 years). Leasehold improvements are stated at cost and amortized on a straight-line basis over the shorter of the estimated useful life of the asset or the lease term.

Impairment of Long-Lived Assets

If indicators of impairment exist, we assess the recoverability of the affected long-lived assets by determining whether the carrying value of such assets can be recovered through undiscounted future operating cash flows. If impairment is indicated, we measure the amount of such impairment by comparing the carrying value of the asset to the fair value of the asset and record the impairment as a reduction in the carrying value of the related asset with a corresponding charge to operating expenses. Estimating the undiscounted future operating cash flows associated with long-lived assets requires judgment and assumptions that could differ materially from actual results.

84

Leases

We determine if an arrangement is a lease or contains lease components at inception. Operating leases with an initial term greater than 12 months are recorded as lease liabilities with corresponding right-of-use (“ROU”) lease assets on the consolidated balance sheets. ROU lease assets represent our right to use the underlying assets over the lease term, and lease liabilities represent the present value of our obligation to make lease payments arising from the lease. Lease liabilities are recognized at the lease commencement based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. We use the implicit rate when readily determinable. The ROU lease assets equal the lease liabilities, less unamortized lease incentives, unamortized initial direct costs and the cumulative difference between rent expense and amounts paid under the lease. The lease term includes any option to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense is recognized on a straight-line basis over the lease term. We have lease agreements with both lease and non-lease components, which are generally accounted for separately.

Revenue Recognition

Revenue is recognized in accordance with the Financial Accounting Standards Board (the “FASB”) ASC Topic 606, Revenue from Contracts with Customers (“Topic 606”). Topic 606 is based on the principle that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.

Product Sales

Our Products are distributed in the U.S. through a limited number of Customers that resell to healthcare providers and hospitals, the end users of our Products.

Revenue is recognized in an amount that reflects the consideration we expect to receive in exchange for our Products. To determine revenue recognition for contracts with customers within the scope of Topic 606, we perform the following 5 steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations of the contract(s); (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract(s); and (v) recognize revenue when (or as) we satisfy the performance obligations.

Product Sales Allowances

We recognize product sales allowances as a reduction of product sales in the same period the related revenue is recognized. Product sales allowances are based on amounts owed or to be claimed on the related sales. Such variable consideration includes estimates that take into consideration the terms of our agreements with Customers, historical product returns, rebates or discounts taken, the shelf life of the product and specific known market events, such as competitive pricing and new product introductions. If actual future results vary from our estimates, we may need to adjust these estimates, which could have an effect on product sales and earnings in the period of adjustment. Our product sales allowances include:

Product Returns—We allow our Customers to return product for credit for up to 12 months after its product expiration date. As such, there may be a significant period of time between the time the product is shipped and the time the credit is issued on returned product.

Distributor Fees—We pay distribution service fees to our Customers based on a contractually fixed percentage of the wholesale acquisition cost and fees for data. These fees are paid no later than two months after the quarter in which product was shipped.

Group Purchasing Organization (“GPO”) Discounts and Rebates—We offer cash discounts to GPO members. These discounts are taken when the GPO members purchase product from our Customers, who

85

then charge back to us the discount amount. Additionally, we offer volume and contract-tier rebates to GPO members. Rebates are based on actual purchase levels during the quarterly rebate purchase period.

GPO Administrative Fees—We pay administrative fees to GPOs for services and access to data. These fees are based on contracted terms and are paid after the quarter in which the product was purchased by the GPOs’ members.

Medicaid Rebates—We participate in Medicaid rebate programs, which provide assistance to certain low-income patients based on each individual state’s guidelines regarding eligibility and services. Under the Medicaid rebate programs, we pay a rebate to each participating state, generally within three months after the quarter in which the product was sold.

We believe our estimated allowance for product returns requires a high degree of judgment and is subject to change based on our experience and certain quantitative and qualitative factors. We believe our estimated allowances for distributor fees, GPO discounts, rebates and administrative fees and Medicaid rebates do not require a high degree of judgment because the amounts are settled within a relatively short period of time.

Our product sales allowances and related accruals are evaluated each reporting period and adjusted when trends or significant events indicate that a change in estimate is appropriate. Changes in product sales allowance estimates could materially affect our results of operations and financial position.

Accrued Clinical Liabilities

We accrue clinical costs based on work performed, which relies on estimates of the progress of the trials and the related expenses incurred. Clinical trial related contracts vary significantly in duration, and may be for a fixed amount, based on the achievement of certain contingent events or deliverables, a variable amount based on actual costs incurred, capped at a certain limit or contain a combination of these elements. Revisions are recorded to research and development expense in the period in which the facts that give rise to the revision become known. Historically, revisions have not resulted in material changes to research and development expense; however, a modification in the protocol of a clinical trial or cancellation of a clinical trial could result in a material charge to our results of operations.

Research and Development Expense

All costs of research and development are expensed in the period incurred. Research and development expense primarily consists of personnel and related costs, stock-based compensation expense, fees paid to outside service providers and consultants, facilities costs and materials used in clinical and preclinical trials and research and development.

Patent Costs

We incur outside legal fees in connection with filing and maintaining our various patent applications. All patent costs are expensed as incurred and are included in general and administrative expense in the consolidated statements of operations and comprehensive loss.

Stock-Based Compensation Expense

We estimate the fair value of stock-based payment awards using the Black-Scholes option pricing model. This fair value is then amortized using the straight-line single-option method of attributing the value of stock-based compensation to expense over the requisite service periods of the awards. The Black-Scholes option pricing model requires the input of complex and subjective assumptions, including each option’s expected life and price volatility of the underlying stock.

86

As stock-based compensation expense is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Forfeitures are estimated based on historical data.

Warrants

We have issued warrants to purchase shares of our common stock in conjunction with certain equity financings or in exchange for services. The terms of the warrants were evaluated to determine the appropriate classification as equity or a liability.

Income Taxes

We recognize the impact of a tax position in our consolidated financial statements if the position is more likely than not to be sustained on examination and on the technical merits of the position. The total amount of unrecognized tax benefits, if recognized, would affect other tax accounts, primarily deferred taxes in future periods, and would not affect our effective tax rate, since we maintain a full valuation allowance against our deferred tax assets (see Note 12). We recognize interest and penalties related to income tax matters in income tax expense.

Comprehensive Loss

Comprehensive loss is defined as the change in equity during a period from transactions and other events and circumstances from non-owner sources. Net changes in unrealized gains and losses on available-for-sale securities are included in other comprehensive loss and represent the difference between our net loss and comprehensive net loss for both periods presented.

Net Loss per Share

Basic net loss per share is calculated by dividing the net loss by the weighted-average number of common shares outstanding for the period, without consideration of common stock equivalents. Diluted net loss per share is computed by dividing the net loss by the weighted-average number of common shares and common stock equivalents outstanding for the period determined using the treasury stock method. For purposes of this calculation, stock options, restricted stock units, warrants and shares of common stock underlying convertible notes are considered to be common stock equivalents and are included in the calculation of diluted net loss per share only when their effect is dilutive.

Because we have incurred a net loss for both periods presented in the consolidated statements of operations and comprehensive loss, the following common stock equivalents were not included in the computation of net loss per share because their effect would be anti-dilutive (in thousands):

December 31,

Restricted stock units outstanding 3,167 2,803

Warrants outstanding 8,548 —

Shares of common stock underlying convertible notes outstanding 9,819 9,819

Recent Accounting Pronouncements

Adopted in 2022

In August 2020, the FASB issued ASU No. 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 (“ASU 2020-06”). ASU 2020-06 simplifies the accounting for convertible instruments primarily by eliminating the existing cash conversion and beneficial conversion models within Subtopic 470-20, which will result in fewer embedded conversion options being accounted for separately from the debt host. ASU 2020-06 also amends and simplifies the calculation of earnings per share relating to convertible instruments. On January 1, 2022, we adopted the provisions of ASU 2020-06 using the modified retrospective approach, which did not have a material impact on our results of operations, cash flows, financial condition and related disclosures (see Note 8 for further details).

Fair Value Measurements

Fair value is defined as the exchange price that would be received for 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. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The FASB ASC Topic 820, Fair Value Measurements & Disclosures, establishes a fair value hierarchy which prioritizes the inputs used in measuring fair value as follows:

Level 1—Observable inputs such as quoted prices in active markets for identical assets or liabilities.

Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

We measure cash, cash equivalents and short-term investments at fair value on a recurring basis. The fair values of these such assets were as follows (in thousands):

As of December 31, 2022, cash equivalents included $1.5 million of available-for-sale securities with contractual maturities of three months or less and short-term investments included $69.5 million of available-for-sale securities with contractual maturities of three months to one year. As of December 31, 2021, cash equivalents included $4.5 million of available-for-sale securities with contractual maturities of three months or less and short-term investments included $67.0 million of available-for-sale securities with contractual maturities of three months to one year. The money market funds as of December 31, 2022 and 2021 are included in cash and cash equivalents on the consolidated balance sheets.

Commitments and Contingencies

Leases

As of December 31, 2022, we had an operating lease for 52,148 square feet of laboratory and office space in San Diego, California, with a lease term that expires on December 31, 2025. In October 2021, we entered into a sublease agreement to sublet 23,873 square feet of laboratory and office space. The space was delivered to the subtenant in March 2022. As a result of the sublease agreement, our one 5-year option to renew the lease on expiration applies only with respect to our remaining 28,275 square feet of laboratory and office space. During the year ended December 31, 2022, we paid $2.9 million for our operating lease.

Annual future minimum lease payments as of December 31, 2022 are as follows (in thousands):

Year ended December 31:

Thereafter —

Total future minimum lease payments 9,096

Less: discount (903 )

Total lease liabilities $ 8,193

Rent expense under all operating leases totaled $2.8 million and $3.7 million for the years ended December 31, 2022 and 2021, respectively.

Development Agreements

We enter into agreements with clinical sites and clinical research organizations for the conduct of our clinical trials and contract manufacturing organizations for the manufacture and supply of preclinical, clinical and commercial materials and drug product. We make payments to these clinical sites and clinical research organizations based in part on the number of eligible patients enrolled and the length of their participation in the clinical trials. In some of our agreements with contract manufacturing organizations, we are required to meet minimum purchase obligations. Under certain of these agreements, we may be subject to penalties in the event that we prematurely terminate these agreements. At this time, due to the variability associated with clinical site agreements, contract research organization agreements and contract manufacturing agreements, we are unable to estimate with certainty the future costs we will incur. We intend to use our current financial resources to fund our obligations under these commitments.

Purchase Obligations

At December 31, 2022, purchase obligations primarily consisted of non-cancellable commitments with third-party manufacturers in connection with the manufacturing of our commercial products. Total purchase obligations of $103.7 million were not included in our consolidated financial statements for the year ended December 31, 2022, with $38.7 million due in one year and $65.0 million due within two to three years.

7.

Reorganization

In June 2022, we implemented a restructuring plan under which we provided employees one-time severance payments upon termination, continuation of benefits for a specific period of time, outplacement services and certain stock award modifications. The total amount incurred for these activities is $5.4 million, $5.0 million of which is primarily for severance and $0.4 million of which is for non-cash, stock-based compensation expense related to stock award modifications. For the year ended December 31, 2022, we recognized $5.4 million of the total expense, $4.2 million of which was included in research and development expense, $1.0 million of which was included in sales and marketing expense, and $0.2 million of which was included in general and administrative expense. We anticipate that the cash payments due to terminated employees will be substantially completed in the first quarter of 2023. As of December 31, 2022, we have paid $4.1 million of the total cash severance charges.

93

In October 2021, we implemented a restructuring plan under which we provided employees one-time severance payments upon termination, continued benefits for a specific period of time, outplacement services and certain stock option modifications. The total expense for these activities was $1.4 million, $1.3 million of which was primarily for severance and $0.1 million of which was for non-cash, stock-based compensation expense related to stock option modifications. The total expense was recognized in the fourth quarter of 2021, with $1.2 million included in research and development expense and $0.2 million included in sales and marketing expense. As of December 31, 2022, we have paid $1.3 million of the total cash severance charges.

We have accounted for these expenses in accordance with the FASB ASC Topic 420, Exit or Disposal Cost Obligations.

Convertible Notes

Senior Unsecured Convertible Notes

In May 2021, we entered into a note purchase agreement with funds affiliated with Baker Bros. Advisors LP for a private placement of $150.0 million in Senior Unsecured Convertible Notes (“Notes”). We received a total of $149.0 million, net of issuance costs, from the issuance of these Notes.

The Notes were issued at par. The Notes bear interest at a rate of 1.5% per annum, payable in cash semi-annually in arrears on June 15th and December 15th of each year, beginning on December 15, 2021. The Notes mature on May 26, 2026, unless earlier converted, redeemed or repurchased.

The Notes will be subject to redemption at our option, between May 24, 2024 and May 24, 2025, but only if the last reported sale price per share of our common stock exceeds 250% of the conversion price for a specified period of time, or on or after May 24, 2025 if the last reported sale price per share of our common stock exceeds 200% of the conversion price for a specified period of time. The redemption price will be equal to the principal amount of the Notes to be redeemed, plus accrued and unpaid interest.

Upon conversion, we will settle the Notes in shares of our common stock. The initial conversion rate for the Notes is 65.4620 shares per $1,000 principal amount of the Notes (equivalent to an initial conversion price of $15.276 per share of common stock).

If a holder of the Notes converts upon a make-whole fundamental change or company redemption, the holder may be eligible to receive a make-whole premium through an increase to the conversion rate.

In May 2021, we filed a registration statement with the SEC to register for resale 12.4 million shares of our common stock underlying the Notes, including the maximum number of shares of common stock issuable under the make-whole premium.

The Notes were accounted for in accordance with ASC Subtopic 470-20, Debt with Conversion and Other Options (“ASC 470-20”) and ASC Subtopic 815-40, Contracts in Entity’s Own Equity (“ASC 815-40”). Under ASC 815-40, to qualify for equity classification (or non-bifurcation, if embedded), the instrument (or embedded feature) must be both (1) indexed to the issuer’s stock and (2) meet the requirements of the equity classification guidance. Based upon our analysis, it was determined that the Notes do contain embedded features indexed to our own stock, but do not meet the requirements for bifurcation, and therefore do not need to be separately accounted for as an equity component. Since the embedded conversion feature meets the equity scope exception from derivative accounting, and, also since the embedded conversion option does not need to be separately accounted for as an equity component under ASC 470-20, the proceeds received from the issuance of the Notes were recorded as a liability on the consolidated balance sheets.

94

We incurred issuance costs related to the Notes of $1.0 million, which we recorded as debt issuance costs and are included as a reduction to the Notes on the consolidated balance sheets. The debt issuance costs are being amortized to interest expense using the effective interest rate method over the term of the Notes, resulting in an effective interest rate of 1.6%. For the year ended December 31, 2022, interest expense related to the Notes was $2.5 million, which included $2.3 million related to the stated interest rate and $0.2 million related to the amortization of debt issuance costs. As of December 31, 2022, the carrying value of the Notes was $149.3 million, which is comprised of the $150.0 million principal amount of the Notes outstanding, less debt issuance costs of $0.7 million.

Senior Secured Convertible Notes

In April 2011, we entered into a securities purchase agreement for a private placement of up to $4.5 million in Senior Secured Convertible Notes (“Convertible Notes”) with certain investors, including Tang Capital Partners, LP. We received a total of $4.3 million, net of issuance costs, from the issuance of these Convertible Notes. The Convertible Notes bore interest at 6% per annum, payable quarterly in cash or in additional principal amount of Convertible Notes, at the election of the purchasers. The Convertible Notes matured on May 2, 2021.

The Convertible Notes contained an embedded conversion feature that was in-the-money on the issuance dates. Based on an effective fixed conversion rate of 1,250 shares for every $1,000 of principal and accrued interest due under the Convertible Notes, the total conversion benefit at issuance exceeded the loan proceeds. Therefore, a debt discount was recorded in an amount equal to the face value of the Convertible Notes on the issuance dates, and we amortized the resultant debt discount over the respective 10-year term of the Convertible Notes which ended in May 2021. For the year ended December 31, 2021 interest expense relating to the stated rate was $0.2 million and interest expense relating to the amortization of the debt discount was $0.8 million.

In May 2021, holders of the Convertible Notes exercised their right to convert the outstanding principal and accrued interest into shares, which resulted in the issuance of 9.8 million shares of common stock. Upon issuance of these shares, there were no remaining obligations under the Convertible Notes.

Stockholders’ Equity

2022 Private Placement

On August 8, 2022, we entered into an agreement to sell 16.1 million shares of our common stock in a private placement at a purchase price of $3.10 per share. In addition, as a component of the private placement, we agreed to sell 8.5 million pre-funded warrants to purchase shares of our common stock at a purchase price of $3.0999 per share. The pre-funded warrants have an exercise price of $0.0001 per share. The total net proceeds from the sale of the common stock and pre-funded warrants is $75.1 million (net of $1.4 million in issuance costs). In October 2022, we filed a registration statement with the SEC to register for resale 24.6 million shares of our common stock. The registration statement was declared effective on October 18, 2022.

Public Offering Warrants

In June 2014, as a component of our public offering, we sold 600,000 pre-funded warrants to purchase shares of our common stock. The pre-funded warrants have an exercise price of $0.01 per share and expire on June 30, 2021. During the year ended December 31, 2019, warrant holders exercised 132,130 warrants, which resulted in the issuance of 132,130 shares for net cash proceeds of $1,321. During the year ended December 31, 2020, warrant holders exercised 267,870 warrants, which resulted in the issuance of 267,870 shares for net cash proceeds of $2,679. In April 2021, warrant holders exercised 195,574 warrants using the cashless exercise provision, which resulted in the issuance of 195,461 shares and no cash proceeds. As of December 31, 2021, no warrants from the June 2014 public offering remain outstanding.

Equity Incentive Plans

Employee Stock Purchase Plan

In 1997, our stockholders approved our Employee Stock Purchase Plan (“ESPP”) at which time a maximum of 10,000 shares of common stock were available for issuance. In December 2007, May 2009, June 2011, May 2014, May 2015, June 2016, June 2017, June 2019, June 2021 and May 2022, our stockholders authorized increases in the number of shares reserved for issuance under the ESPP by 5,000, 10,000, 25,000, 25,000, 100,000, 100,000, 200,000, 300,000, 200,000 and 850,000 shares, respectively, for a total of 1,825,000 shares reserved at December 31, 2022. Under the terms of the ESPP, employees can elect to have up to a maximum of 10% of their base earnings withheld to purchase shares of our common stock. The purchase price of the stock is 85% of the lower of the closing prices for our common stock on either: (i) the first trading day in the enrollment period, as defined in the ESPP, in which the purchase is made, or (ii) the purchase date. The length of the enrollment period is 6 months. Enrollment dates are the first business day of May and November. Under the ESPP, we issued 406,421 and 175,228 shares in 2022 and 2021, respectively. The weighted-average exercise price per share of the purchase rights exercised during 2022 and 2021 was $3.55 and $12.21, respectively. As of December 31, 2022, 1,180,399 shares of common stock have been issued under the ESPP and 644,601 shares of common stock are available for future issuance.

Stock Option Plans

We currently have one stock option plan from which we can grant options and restricted stock awards to employees, officers, directors and consultants. In December 2007, the stockholders approved our 2007 Amended and Restated Equity Incentive Plan (“2007 Plan”) at which time a maximum of 150,000 shares of common stock were available for grant. In May 2010, June 2011, May 2014, May 2015, June 2016, June 2017, June 2019, June 2021 and May 2022, our stockholders approved amendments to our 2007 Plan to increase the maximum number of shares of common stock available for grant by 100,000, 4,500,000, 1,750,000, 4,300,000, 3,000,000, 5,000,000, 7,000,000, 2,000,000 and 2,900,000 shares of common stock, respectively, resulting in an aggregate of 30,700,000 shares of common stock authorized for issuance as of December 31, 2022. At December 31, 2022, there were 985,119 shares available for future grant under the 2007 Plan. Any shares that are issuable on exercise of options granted that expire, are cancelled or that we receive pursuant to a net exercise of options are available for future grant and issuance.

In 2014 and 2013, we granted options to certain employees outside of our stockholder approved stock option plans. All options to purchase our common stock were granted with an exercise price that equals fair market value of the underlying common stock on the grant dates and expire no later than 10 years from the date of grant. The options are exercisable in accordance with vesting schedules that generally provide for them to be fully vested and exercisable 4 years after the date of grant, provided, however, that we have also issued stock options awards that are subject to performance vesting requirements. All stock option grants issued outside of our stockholder approved plans have been registered on Form S-8 with the SEC.

96

In 2020, we began granting restricted stock units (“RSUs”) to employees and non-employee directors pursuant to the 2007 Plan. We satisfy such grants through the issuance of new shares upon vesting.

The following table summarizes the stock option plan activity:

For the year ended December 31, 2022, equity awards cancelled (included in options outstanding) consisted of 1,227,682 options forfeited with a weighted-average exercise price of $15.57 and 2,263,453 options expired with a weighted-average exercise price of $21.47.

As of December 31, 2022, options exercisable have a weighted-average remaining contractual term of 6.4 years. There were no option exercises during the year ended December 31, 2022. The total intrinsic value of stock option exercises, which is the difference between the exercise price and closing price of our common stock on the date of exercise, during the year ended December 31, 2021 was $0.7 million. As of December 31, 2022, there were no options outstanding and exercisable that were in-the-money. As of December 31, 2021, the total intrinsic value of options outstanding and exercisable was $1.7 million.

On December 31, 2022, we had reserved 23,916,746 shares of common stock for future issuance on exercise of outstanding options and vesting of outstanding restricted stock units granted under the 2007 Plan, as well as the non-plan grants.

Stock-Based Compensation

The following table summarizes stock-based compensation expense related to stock-based payment awards pursuant to our equity compensation arrangements (in thousands):

December 31,

Total stock-based compensation expense $ 42,980 $ 46,851

As of December 31, 2022, there was $51.9 million of total unrecognized compensation cost related to non-vested, stock-based payment awards granted under all of our equity compensation plans and all non-plan option grants. Total unrecognized compensation cost will be adjusted for future changes in estimated forfeitures. We expect to recognize this compensation cost over a weighted-average period of 1.9 years.

The fair value of RSUs is estimated based on the closing market price of our common stock on the date of the grant. RSUs generally vest quarterly over a four-year period.

We estimated the fair value of each option grant and ESPP purchase right on the date of grant using the Black-Scholes option pricing model with the following weighted-average assumptions:

Options:

December 31,

Risk-free interest rate 3.3 % 1.1 %

Dividend yield — % — %

Expected life (years) 6 6

98

ESPP:

December 31,

Risk-free interest rate 3.2 % 0.1 %

Dividend yield — % — %

Expected life (months) 6 6

The weighted-average fair value of options granted was $1.71 and $7.10 for the years ended December 31, 2022 and 2021, respectively.

The weighted-average fair value of shares purchased through the ESPP was $1.65 and $3.64 for the years ended December 31, 2022 and 2021, respectively.

The risk-free interest rate assumption is based on observed interest rates on U.S. Treasury debt securities with maturities close to the expected term of our employee and director stock options and ESPP purchases.

The dividend yield assumption is based on our history and expectation of dividend payouts. We have never paid dividends on our common stock, and we do not anticipate paying dividends in the foreseeable future.

We used our historical stock price to estimate volatility.

The expected life of employee and director stock options represents the average of the contractual term of the options and the weighted-average vesting period, as permitted under the simplified method. We have elected to use the simplified method, as we do not have enough historical exercise experience to provide a reasonable basis on which to estimate the expected term. The expected life for the ESPP purchase rights is 6 months, which represents the length of each purchase period.

11.

Employee Benefit Plan

We have a defined contribution 401(k) plan (“Plan”) covering substantially all of our employees. In the past three calendar years, we made matching cash contributions equal to 50% of each participant’s contribution during the Plan year up to a maximum amount equal to the lesser of 3% of each participant’s annual compensation or $9,150 and $8,700 for the years ended December 31, 2022 and 2021, respectively. Such amounts were recorded as expense in the corresponding years. We may also contribute additional discretionary amounts to the Plan as we determine. For the years ended December 31, 2022 and 2021, we contributed $1.4 million and $1.3 million, respectively, to the Plan. No discretionary contributions have been made to the Plan since its inception.

99

12.

Income Taxes

For the years ended December 31, 2022 and 2021, we did not record a provision for income taxes due to a full valuation allowance against our deferred tax assets.

The difference between the provision for income taxes and income taxes computed using the effective U.S. federal statutory rate is as follows (in thousands):

December 31,

Tax at statutory federal rate $ (38,225 ) $ (46,343 )

State tax, net of federal benefit (13,898 ) (8,683 )

Research and development credits (3,531 ) (4,173 )

Stock-based compensation expense 5,857 4,584

Employee retention credit adjustment (1,265 ) —

Provision for income taxes $ — $ —

Deferred income tax assets and liabilities arising from differences between accounting for financial statement purposes and tax purposes, less valuation allowance at year-end are as follows (in thousands):

December 31,

Deferred tax assets:

Section 174 capitalized research and development 20,903 —

Deferred tax liabilities:

Right-of-use lease assets (1,914 ) (2,420 )

Total gross deferred tax liabilities (1,914 ) (2,420 )

Net deferred tax assets $ — $ —

We have established a valuation allowance to offset net deferred tax assets as of December 31, 2022 and 2021 due to the uncertainty of realizing future tax benefits from such assets.

As of December 31, 2022, we had federal and state net operating loss (“NOL”) carryforwards of $1.3 billion and $891.7 million, respectively. The federal NOL carryforwards consist of $542.7 million generated before January 1, 2018, which will begin to expire in 2023, and $718.2 million that can be carried forward indefinitely, but are subject to the 80% taxable income limitation. The state NOL carryforwards will begin to expire in 2028.

As of December 31, 2022, we had federal and state research and development credit carryforwards of $49.3 million and $22.2 million, respectively. The federal research and development credit carryforwards will begin to expire in 2023. The state research and development credit carryforwards will be carried forward indefinitely.

100

Internal Revenue Code (“IRC”) Sections 382 and 383 place a limitation on the amount of taxable income that can be offset by NOL and credit carryforwards after a change in control (generally greater than 50% change in ownership within a three-year period) of a loss corporation. Generally, after a change in control, a loss corporation cannot deduct NOL and credit carryforwards in excess of the IRC Sections 382 and 383 limitation. State jurisdictions have similar rules. We have previously performed an analysis of IRC Sections 382 and 383 through 2018 and determined there were ownership changes in 2007, 2011 and 2013. We are currently in the process of updating our IRC Sections 382 and 383 analysis through 2021. The limitation in the federal and state NOL and research and development credit carryforwards that expire unused would reduce the deferred tax assets, which are fully offset by a valuation allowance.

We file U.S. and state income tax returns with varying statutes of limitations. The tax years from 2002 to 2022 remain open to examination due to the carryover of unused NOL carryforwards and tax credits.

A reconciliation of our unrecognized tax benefits is as follows (in thousands):

Year Ended December 31,

Balance at beginning of year $ 9,631 $ 7,406

Increase (decrease) for tax positions of prior years (200 ) 107

Increase based on tax positions related to current year 1,804 2,118

Due to our valuation allowance, the $11.2 million of unrecognized tax benefits would not affect the effective tax rate, if recognized. It is the Company’s practice to recognize interest and penalties related to income tax matters in income tax expense. As of December 31, 2022, we had no accrued interest and penalties related to uncertain tax positions. We do not expect any material changes to the estimated amount of liability associated with our uncertain tax positions within the next 12 months.

On March 27, 2020, the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”) was enacted and signed into law in response to the COVID-19 pandemic. The CARES Act includes changes to the tax provisions that benefits business such as the Employee Retention Credit (“ERC”). The ERC provides an eligible employer with a tax credit that is allowed against certain employment taxes. We qualified for federal government assistance through the ERC provisions for the period between January 1, 2021 and September 30, 2021. We recognize government grants when there is reasonable assurance of compliance with grant conditions and receipt of the credits. As of December 31, 2022, we expect one-time refunds totaling $6.0 million, which are included in the consolidated balance sheets as prepaid expenses and other current assets, as well as in the consolidated statements of operations and comprehensive loss as an offset to the related employee expenses within research and development, general and administrative, and sales and marketing expenses.

Beginning January 1, 2022, the Tax Cuts and Jobs Act (the “Tax Act”) eliminated the option to deduct researchand development expenditures in the current year and requires taxpayers to capitalize such expenses pursuant to IRC Section 174. The capitalized expenses are amortized over a 5-year period for domestic expenses and over a 15-year period for foreign expenses. As a result of this provision of the Tax Act, deferred tax assets related to capitalized research expenses increased by $21 million.

ITEM 9A. CONTROLS AND PROCEDURES.

(a)

Disclosure Controls and Procedures

Our management, with the participation of our principal executive and principal financial and accounting officers, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (“Exchange Act”)) as of December 31, 2022. Based on this evaluation, our principal executive and principal financial and accounting officers concluded that our disclosure controls and procedures were effective as of December 31, 2022.

(b)

Management Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rule 13a-15(f) and Rule 15d-15(f) promulgated under the Exchange Act as a process designed by, or under the supervision of, our principal executive and principal financial officers and effected by our Board of Directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the U.S. and includes those policies and procedures that:

pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets;

provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with accounting principles generally accepted in the U.S., and that receipts and expenditures are being made only in accordance with authorizations of our management and directors; and

provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. 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.

Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2022. In making this assessment, our management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control-Integrated Framework (2013).

Based on our assessment, management concluded that, as of December 31, 2022, our internal control over financial reporting was effective based on those criteria.

This Annual Report does not include an attestation report of the Company's registered public accounting firm due to the Company meeting the definition of a smaller reporting company and the established rules of the SEC related to smaller reporting companies.

(c)

Changes in Internal Control Over Financial Reporting

There have been no significant changes in our internal control over financial reporting that occurred during the period covered by this Annual Report on Form 10-K that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Filing HTML rendered to line-structured narrative text by the shipped reducer (datafeeds.edgar_fulltext.visible_text, keep_table_headers=True): scripts and inline-XBRL headers are dropped, and table content is reduced to its short label cells — numeric table data is not rendered and is therefore not counted. The same rendering is used for every year, so a year-over-year comparison is like for like.

The text is our rendering of the filing, not a facsimile: original pagination, typography and tables are not reproduced, and the numbers live in the financial statements (FA).

The outline locates item HEADINGS in this document. Only Items 1A and 7 have certified boundaries elsewhere in the terminal (the redline and the narrative-overlap number); every span here runs from one heading found to the next heading found.

How the outline was chosen. It is the longest chain of item headings that runs forward through both the document and the standard item order: 22 headings are on that chain and 16 further heading-shaped lines are not — the table-of-contents echo of every item, cross-references and exhibit-list mentions. Each entry's length is measured from its heading to the next heading on the chain.
