Notes to Condensed Consolidated Financial Statements

(Unaudited)

In this Quarterly Report on Form 10-Q, all references to “Heron,” the “Company,” “we,” “us,” “our” and similar terms refer to Heron Therapeutics, Inc. and its wholly owned subsidiary, Heron Therapeutics B.V. Heron Therapeutics®, the Heron logo, ZYNRELEF®, APONVIE®, CINVANTI®, SUSTOL®, and Biochronomer® are our trademarks. All other trademarks appearing or incorporated by reference into this Quarterly Report on Form 10-Q are the property of their respective owners.

1. 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.

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

As of March 31, 2024, we had cash, cash equivalents and short-term investments of $71.5 million. Based on our current operating plan and projections, management believes that the Company's cash, cash equivalents and short-term investments will be sufficient to meet the Company's anticipated cash requirements for a period of at least one year from the date this Quarterly Report on Form 10-Q is filed with the U.S. Securities and Exchange Commission (“SEC”).

2. Basis of Presentation

The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and the requirements of the SEC for interim reporting. Accordingly, since they are interim statements, they do not include all of the information and disclosures required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three months ended March 31, 2024 are not necessarily indicative of the results that may be expected for other quarters or the year ending December 31, 2024. The condensed consolidated balance sheet as of December 31, 2023 has been derived from the audited financial statements as of that date. For more complete financial information, these condensed consolidated financial statements and the notes thereto should be read in conjunction with the audited financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2023, which was filed with the SEC on March 12, 2024.

Reclassification of Certain Expenses

The condensed consolidated statements of operations and comprehensive loss for the three months ended March 31, 2023 reflects reclassification of certain expenses from research and development to general and administrative expenses to align with the Company's presentation for the three months ended March 31, 2024 as a result of the restructuring implemented in 2023, the realignment of the Company's departments and the function of the expenses incurred. This presentation results in no change to total operating expenses, loss from operations or net loss and no pro forma financial information is necessary.

3. Accounting Policies

Principles of Consolidation

The accompanying condensed 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 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 condensed 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 condensed 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 income (loss) and realized gains and losses included in other income (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 within other income (expense), net.

Our bank and investment accounts have been placed under a control agreement in accordance with our Working Capital Line of Credit (see Note 9).

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 with respect to our cash, cash equivalents and short-term investments, however, any loss incurred or a lack of access to such funds could have a significant adverse impact on the Company's financial condition, results of operations and cash flows.

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.

ZYNRELEF, APONVIE, CINVANTI and SUSTOL (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 four major Customers, each of which comprised 10% or more of our product sales:


	Net Product Sales			Accounts Receivable
	Three Months Ended March 31, 2024			As of March 31, 2024
Customer A		38.0	%		37.0	%
Customer B		24.0	%		23.0	%
Customer C		20.0	%		20.0	%
Customer D		17.0	%		20.0	%
Total		99.0	%		100.0	%

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.

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.

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 condensed 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 elected the practical expedient to not separate lease and non-lease components.

Revenue Recognition

Revenue is recognized in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“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 five 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. We recognize revenue from Product sales when there is a transfer of control of the Product to our Customers. We typically determine transfer of control based on when the Product is delivered, and title passes to our Customers.

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 beginning three months prior to the product expiration date and up to 12 months after the 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 costs 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 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 GPO's 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 six months after the quarter in which the product was sold.

•

Prompt Pay Discounts—We may provide discounts on product sales to our Customers for prompt payment based on contractual terms.

We believe our estimated allowance for product returns and GPO discounts 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 rebates and administrative fees, Medicaid rebates and prompt pay discounts 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.

The following table provides disaggregated net product sales (in thousands):


	Three Months Ended March 31,
	2024		2023
CINVANTI net product sales	$	25,617	$	22,855
SUSTOL net product sales		3,615		2,983
ZYNRELEF net product sales		5,013		3,533
APONVIE net product sales		425		244
Total net product sales	$	34,670	$	29,615

The following table provides a summary of activity with respect to our product returns, distributor fees and discounts, rebates and administrative fees, which are included in other accrued liabilities on the condensed consolidated balance sheets (in thousands):


	Product Returns			Distributor Fees			Discounts, Rebates and Administrative Fees			Total

Payments/credits		(237	)		(6,085	)		(45,823	)		(52,145	)
Balance at March 31, 2024	$	2,841		$	4,989		$	30,842		$	38,672

Comprehensive Income (Loss)

Comprehensive income (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 income (loss) and represent the difference between our net loss and comprehensive loss for all periods presented.

Net Loss per Share

Basic net loss per share is calculated by dividing the net loss by the weighted-average number of shares of common stock outstanding for the period, including pre-funded warrants to purchase shares of common stock. Diluted net loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock 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 all periods presented in the unaudited condensed 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):


	March 31,
	2024		2023
Stock options outstanding		29,380		21,376
Restricted stock units outstanding		1,973		3,851
Warrants outstanding		298		8,548
Shares of common stock underlying convertible notes outstanding		9,819		9,819

Recent Accounting Pronouncements

From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies that we adopt as of the specified effective date. We have evaluated recently issued accounting pronouncements and do not believe any will have a material impact on our condensed consolidated financial statements or related financial statement disclosures.

In December 2023, the FASB issued Accounting Standards Update ("ASU") No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures ("ASU 2023-09"), to enhance income tax reporting disclosures and require disclosure of specific categories in the tabular rate reconciliation. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024, on

a prospective basis. Early adoption and retrospective application are permitted. We are currently evaluating the impact on our disclosures.

4. 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 and 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 such assets were as follows (in thousands):

We have not transferred any investment securities between the three levels of the fair value hierarchy, during the three months ended March 31, 2024 or March 31, 2023.

As of March 31, 2024, cash equivalents included $5.2 million of available-for-sale securities with contractual maturities of three months or less and short-term investments included $21.4 million of available-for-sale securities with contractual maturities of three months to one year. As of December 31, 2023, cash equivalents included $5.3 million of available-for-sale securities with contractual maturities of three months or less and short-term investments included $51.7 million of available-for-sale securities with contractual maturities of three months to one year. The money market funds as of March 31, 2024 and December 31, 2023 are included in cash and cash equivalents on the condensed consolidated balance sheets.

A company may elect to use fair value to measure accounts receivable, available-for-sale securities, accounts payable, guarantees and issued debt, among others. 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.

Financial instruments, including cash, 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. Our notes payable and convertible notes payable outstanding at March 31, 2024 and December 31, 2023 do not have a readily available ascertainable market value; however, their carrying value, which is measured at carrying value less unamortized debt issuance costs and debt discounts, is considered to approximate their fair value.

The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. We regularly monitor and evaluate the realizable value of our marketable securities. We did not recognize any impairment losses during the three months ended March 31, 2024 and 2023.

Unrealized gains and losses associated with our investments are reported in accumulated other comprehensive income (loss). Realized gains and losses associated with our investments, if any, are reported in the statements of operations and comprehensive loss. We did not recognize any realized gains or losses during the three months ended March 31, 2024 or March 31, 2023.

There were no such charges incurred during the three months ended March 31, 2024.

7. Leases

As of March 31, 2024, 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 five-year option to renew this lease on expiration applies only with respect to our remaining 28,275 square feet of laboratory and office space.

We also have an operating lease through which we sublease 5,840 square feet of office space in Cary, North Carolina, with a lease term that expires on April 30, 2025.

During the three months ended March 31, 2024, we recognized $0.7 million of operating lease expense and we paid $0.8 million for our operating leases.

8. Reorganizations

June 2023 Reorganization

In June 2023, 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 was $4.2 million, which primarily consists of severance payments to terminated employees. During the three months ended March 31, 2024, we paid $0.5 million of the total cash severance charges. As of March 31, 2024, we have completed payment of the cash severance charges.

Executive Officer Departures

During the second and third quarters of 2023, we also implemented changes to our executive leadership structure. In connection with these changes, we provided five executive officers with one-time severance payments upon termination, continued benefits for a specified period of time, and certain stock option modifications. The total expense for these activities was $13.4 million, $4.7 million of which was primarily for severance and $8.7 million of which was for non-cash, stock-based compensation expense, which was

recognized in 2023. During the three months ended March 31, 2024, we paid $0.1 million of the total cash severance charges. As of March 31, 2024, we have completed payment of the cash severance charges.

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

9. Long-Term Debt and Convertible Notes

Working Capital Facility Agreement

On August 9, 2023, we entered into a working capital facility agreement (the “Loan Agreement”) with Hercules Capital, Inc., as administrative agent and collateral agent, and the lenders party thereto (the “Lenders”). The Loan Agreement provides an aggregate principal amount of up to $50.0 million with tranched availability as follows: $25.0 million at closing (“tranche 1A”), $5.0 million available through December 15, 2024 (“tranche 1B”), and $20.0 million available from the earlier of: (1) the full draw of tranche 1B and (2) the expiration of tranche 1B, and available through December 15, 2025 (“tranche 1C”), and in the case of tranches 1B and 1C, subject to certain customary conditions to draw down.

The Loan Agreement has a term of four years, with a springing maturity date that is 91 days prior to the stated maturity of our Notes (as defined below) (if still outstanding at such time). The loans thereunder do not have any scheduled amortization payments and accrue interest at a floating rate equal to, as of closing, 9.95% per annum, payable in cash on a monthly basis and upon maturity or payoff. In addition, under the terms of the Loan Agreement, the loans also accrue paid-in-kind interest at a fixed-rate of 1.5% per annum which is due upon maturity or payoff.

In addition, in connection with the tranche 1A funding, we issued warrants to the Lenders to purchase up to 297,619 shares of our common stock at an exercise price of $1.68 per share (the "Lender Warrants"). The Lender Warrants are equal to 2.00% of the principal amount of loans funded by the Lenders (the “Warrant Coverage”). The Loan Agreement also requires that we issue additional warrants to the Lenders at the time of each draw down of tranches 1B and 1C with the same Warrant Coverage. Each Lender Warrant is exercisable for seven years from the date of issuance.

The Loan Agreement contains a minimum cash covenant, beginning on the closing date, requiring us to hold cash of no less than $8.5 million, if our market capitalization is less than $400 million. The Loan Agreement also contains customary representations and warranties and customary affirmative and negative covenants, including, among other things, restrictions on indebtedness, liens, investments, mergers, dispositions, prepayment of other indebtedness, and dividends and other distributions, subject to certain exceptions. We were in compliance with all covenants of the Loan Agreement as of March 31, 2024.

The Loan Agreement was accounted for in accordance with ASC Topic 470, Debt, ASC Topic 480, Distinguishing Liabilities from Equity, and ASC Topic 815, Derivatives and Hedging. The initial tranche 1A funding of $25.0 million and the Lender Warrants are accounted for as freestanding debt and equity financial instruments, respectively, as they are legally detachable and separately exercisable. The additional borrowings available under the Loan Agreement plus the additional warrants to purchase shares of our common stock, which would be issued concurrently, are accounted for as a single freestanding financial instrument that are not assets or obligations of ours; this financial instrument meets the loan commitment derivative scope exception and will be accounted for when and if we borrow additional tranches in the future. The initial funding of $25.0 million was recorded as a liability on the condensed consolidated balance sheets.

In connection with the Loan Agreement, we recognized the initial Lender Warrants at their relative fair value of $0.4 million, and we incurred debt issuance costs of $0.6 million, both of which were recorded as debt discounts. The debt discounts and the end of term fee, of $0.8 million, are being amortized and accreted into interest expense using the effective interest rate method over the term of the Loan Agreement, resulting in an effective interest rate of 14.5%. For the three months ended March 31, 2024, interest expense related to the Loan Agreement was $0.9 million, which included $0.6 million related to the stated interest rate, $0.1 million related to paid-in-kind interest, and $0.2 million related to the amortization of the debt discounts. As of March 31, 2024, the carrying value of

tranche 1A was $24.4 million, which is comprised of the $25.0 million principal amount outstanding, $0.2 million of accumulated paid-in-kind interest, less debt discounts of $0.8 million.

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 (the “Notes”). We received a total of $149.0 million, net of issuance costs, from the issuance of the 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 15 and December 15 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 common 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 condensed consolidated balance sheets.

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 condensed 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 three months ended March 31, 2024, interest expense related to the Notes was $0.6 million, which included $563,000 related to the stated interest rate and $52,000 related to the amortization of debt issuance costs. For the three months ended March 31, 2023, interest expense related to the Notes was $0.6 million, which included $563,000 related to the stated interest rate and $51,000 related to the amortization of debt issuance costs. As of March 31, 2024, the carrying value of the Notes was $149.5 million, which is comprised of the $150.0 million principal amount of the Notes outstanding, less debt issuance costs of $0.5 million.

10. Stockholders’ Deficit

2023 Private Placement

On July 21, 2023, we entered into a Securities Purchase Agreement (the “July 2023 Private Placement”) with Rubric Capital Management L.P., Velan Capital, Clearline Capital and Hercules Capital, Inc. (collectively, the “Purchasers”) whereby we sold 20.7 million shares of our common stock in a private placement at a purchase price of $1.37 per share. In addition, as a component of the July 2023 Private Placement, we sold 1.2 million pre-funded warrants to purchase shares of our common stock at a purchase price of $1.3699 per share (the "July 2023 Pre-Funded Warrants"). The July 2023 Pre-Funded Warrants have an exercise price of $0.0001 per share. The total net proceeds from the sale of the common stock and the July 2023 Pre-Funded Warrants is $29.8 million (net of $0.2 million in issuance costs). The July 2023 Private Placement closed on July 25, 2023. In August 2023, we filed a registration statement with the SEC to register for resale 21.9 million shares of our common stock. The registration statement was declared effective on August 31, 2023.

11. Equity Incentive Plan

Option Plan Activity

The following table summarizes the stock option activity for the three months ended March 31, 2024:


	Shares (in thousands)			Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term (Years)
Outstanding at December 31, 2023		24,575		$	7.06		5.60
Granted		6,331		$	2.17
Exercised		(40	)	$	1.88
Expired and forfeited		(1,486	)	$	10.35
Outstanding at March 31, 2024		29,380		$	5.85		7.23

We estimated the fair value of each option grant on the grant date using the Black-Scholes option pricing model and for market-based stock option grants using the Monte Carlo simulation model. The following are the weighted-average assumptions:


	For the Three Months Ended
	March 31,
	2024			2023
Risk-free interest rate		4.2	%		3.7	%
Dividend yield		0.0	%		0.0	%
Volatility		79.7	%		63.9	%
Expected life (years)		4			6

We estimated the fair value of each purchase right granted under our 1997 Employee Stock Purchase Plan, as amended, at the beginning of each new offering period using the Black-Scholes option pricing model. There were no new offering periods during the three months ended March 31, 2024.

The following table summarizes the restricted stock unit activity (“RSUs”) for the three months ended March 31, 2024:


	Shares (in thousands)			Weighted-Average Grant Date Fair Value
Outstanding at December 31, 2023		1,405		$	4.43
Granted		949		$	2.16
Released		(125	)	$	2.56
Expired and forfeited		(256	)	$	3.85
Outstanding at March 31, 2024		1,973		$	3.09

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.

Stock-Based Compensation

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


	Three Months Ended March 31,
	2024		2023
General and administrative	$	1,878	$	3,532
Sales and marketing		796		2,679
Research and development		701		1,736
Total stock-based compensation expense	$	3,375	$	7,947

As of March 31, 2024, there was $21.3 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 three years.

12. Income Taxes

Deferred income tax assets and liabilities are recognized for temporary differences between financial statements and income tax carrying values using tax rates in effect for the years such differences are expected to reverse. Due to uncertainties surrounding our ability to generate future taxable income and consequently realize such deferred income tax assets, a full valuation allowance has been established. We continue to maintain a full valuation allowance against our deferred tax assets as of March 31, 2024.

The impact of an uncertain income tax position on the income tax return must be recognized at the largest amount that is more likely than not to be sustained upon audit by the relevant tax authority. An uncertain income tax position will be recognized when it is more likely than not of being sustained. The disclosures regarding uncertain tax positions included in our Annual Report on Form 10-K for the year ended December 31, 2023, which was filed with the SEC on March 12, 2024, continue to be accurate for the three months ended March 31, 2024.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

Acute Care Product Portfolio

Our Acute Care Product Portfolio consists of ZYNRELEF, which is approved in the U.S. for the management of postoperative pain and APONVIE, which is approved in the U.S. for the prevention of postoperative nausea and vomiting.

ZYNRELEF

ZYNRELEF was initially approved by the FDA in May 2021, and we commenced commercial sales in the U.S. in July 2021. In each of December 2021 and January 2024, the FDA approved an expansion of ZYNRELEF's indication. ZYNRELEF is approved for small-to-medium open abdominal, lower extremity total joint arthroplasty, soft tissue and orthopedic surgical procedures including foot and ankle, and other procedures in which direct exposure to articular cartilage is avoided.

ZYNRELEF is a dual-acting local anesthetic that delivers a fixed-dose combination of the local anesthetic bupivacaine and a low dose of the nonsteroidal anti-inflammatory drug meloxicam. ZYNRELEF is the first and only modified-release local anesthetic to be classified by the FDA as an extended-release product because ZYNRELEF demonstrated in Phase 3 studies significantly reduced pain and significantly increased proportion of patients requiring no opioids through the first 72 hours following surgery compared to bupivacaine solution, the current standard-of-care local anesthetic for postoperative pain control.

In January 2024, we entered into a five-year distributor partnership with CrossLink Life Sciences, LLC (“Crosslink”) to expand the sales network supporting ZYNRELEF. Crosslink will be the lead partner in the U.S. to expand ZYNRELEF promotion for orthopedic indications. The partnership will launch in several phases, initially at a regional level, followed by an expanded national rollout. In total, we anticipate that approximately 650 representatives will be added to Heron’s sales network over 2024.

In March 2022, the Centers for Medicare and Medicaid Services (“CMS”) approved a 3-year transitional pass-through status of ZYNRELEF, which became effective on April 1, 2022, for separate reimbursement outside of the surgical bundle payment in the Hospital Outpatient Department (“HOPD”) setting of care. In addition, in December 2022, H.R. 2617, the omnibus spending bill was approved by Congress that includes a provision requiring CMS to pay for certain non-opioids outside the existing bundled payment for surgeries for the period January 1, 2025 through December 31, 2027.

APONVIE

APONVIE was approved by the FDA in September 2022 and became commercially available in the U.S. in March 2023. APONVIE is indicated for the prevention of postoperative nausea and vomiting (“PONV”) in adults. CMS granted pass-through payment status for APONVIE, effective April 1, 2023.

APONVIE is the first and only intravenous formulation of a substance P/neurokinin-1 (“NK1”) receptor antagonist indicated for PONV. Delivered via a single 30-second intravenous (“IV”) injection, APONVIE has demonstrated rapid achievement of therapeutic drug levels ideally suited for the surgical setting.

Oncology Care Product Portfolio

Our Oncology Care Product portfolio consists of SUSTOL and CINVANTI, which are both approved in the U.S. for the prevention of chemotherapy-induced nausea and vomiting.

SUSTOL

SUSTOL was approved by the FDA in August 2016, and we commenced commercial sales in the U.S. in October 2016.

SUSTOL is indicated in combination with other antiemetics in adults for the prevention of acute and delayed nausea and vomiting associated with initial and repeat courses of moderately emetogenic chemotherapy (MEC) or anthracycline and cyclophosphamide (AC) combination chemotherapy regimens. SUSTOL is an extended-release, injectable 5-hydroxytryptamine type 3 (“5-HT3”) receptor antagonist that utilizes our Biochronomer Technology to maintain therapeutic levels of granisetron for ≥5 days. The SUSTOL global Phase 3 development program was comprised of two, large, guideline-based clinical studies that evaluated SUSTOL’s efficacy and safety in more than 2,000 patients with cancer. SUSTOL’s efficacy in preventing nausea and vomiting was evaluated in both the acute phase (0–24 hours following chemotherapy) and the delayed phase (24–120 hours following chemotherapy).

SUSTOL is the first extended-release 5-HT3 receptor antagonist approved for the prevention of acute and delayed nausea and vomiting associated with both MEC and AC combination chemotherapy regimens. A standard of care in the treatment of breast cancer and other cancer types, AC regimens are among the most commonly prescribed HEC regimens, as defined by both the National Comprehensive Cancer Network (“NCCN”) and the American Society of Clinical Oncology (“ASCO”).

In February 2017, the NCCN included SUSTOL as a part of its NCCN Clinical Practice Guidelines in Oncology for Antiemesis Version 1.2017. The NCCN has given SUSTOL a Category 1 recommendation, the highest-level category of evidence and consensus, for use in the prevention of acute and delayed nausea and vomiting in patients receiving HEC or MEC regimens. The guidelines now identify SUSTOL as a “preferred” agent for preventing nausea and vomiting following MEC. Further, the guidelines highlight the unique, extended-release formulation of SUSTOL.

In January 2018, a product-specific billing code, or permanent J-code (“J-code”), for SUSTOL became available. The new J-code was assigned by CMS and has helped simplify the billing and reimbursement process for prescribers of SUSTOL.

CINVANTI

CINVANTI was approved by the FDA in November 2017, and we commenced commercial sales in the U.S. in January 2018. In each of February 2019 and October 2019, the FDA approved an expansion of CINVANTI of its administration and indication, respectively.

CINVANTI, in combination with other antiemetic agents, is indicated in adults for the prevention of acute and delayed nausea and vomiting associated with initial and repeat courses of highly emetogenic cancer chemotherapy (HEC) including high-dose cisplatin as a single-dose regimen, delayed nausea and vomiting associated with initial and repeat courses of moderately emetogenic cancer chemotherapy (MEC) as a single-dose regimen, and nausea and vomiting associated with initial and repeat courses of MEC as a 3-day regimen.

CINVANTI is an IV formulation of aprepitant, a substance NK1 receptor antagonist. CINVANTI is the first IV formulation to directly deliver aprepitant, the active ingredient in EMEND® capsules. Aprepitant (including its prodrug, fosaprepitant) is a single-agent NK1 receptor antagonist to significantly reduce nausea and vomiting in both the acute phase (0–24 hours after chemotherapy) and the delayed phase (24–120 hours after chemotherapy). CINVANTI is the first IV formulation of an NK1 receptor antagonist indicated for the prevention of acute and delayed nausea and vomiting associated with HEC and nausea and vomiting associated with MEC that is free of synthetic surfactants, including polysorbate 80.

NK1 receptor antagonists are typically used in combination with 5-HT3 receptor antagonists. The only other injectable NK1 receptor antagonist currently approved in the U.S. for both acute and delayed chemotherapy induced nausea and vomiting (“CINV”), EMEND® IV (fosaprepitant), contains polysorbate 80, a synthetic surfactant, which has been linked to hypersensitivity reactions, including anaphylaxis, and infusion site reactions. The CINVANTI formulation does not contain polysorbate 80 or any other synthetic surfactant. Our CINVANTI data has demonstrated the bioequivalence of CINVANTI to EMEND IV, supporting its efficacy for the prevention of both acute and delayed nausea and vomiting associated with HEC and nausea and vomiting associated with MEC. Results also showed CINVANTI was better tolerated in healthy volunteers than EMEND IV, with significantly fewer adverse events reported with CINVANTI.

In January 2019, a J-code for CINVANTI became available. The new J-code was assigned by CMS and has helped simplify the billing and reimbursement process for prescribers of CINVANTI.

Biochronomer Technology

Our proprietary Biochronomer Technology is designed to deliver therapeutic levels of a wide range of otherwise short-acting pharmacological agents over a period from days to weeks with a single administration. Our Biochronomer Technology consists of polymers that have been the subject of comprehensive animal and human toxicology studies that have shown evidence of the safety of the polymer. When administered, the polymers undergo controlled hydrolysis, resulting in a controlled, sustained release of the pharmacological agent encapsulated within the Biochronomer-based composition. Furthermore, our Biochronomer Technology is designed to permit more than one pharmacological agent to be incorporated, such that multimodal therapy can be delivered with a single administration.

Critical Accounting Estimates

The discussion and analysis of our financial condition and results of operations are based on our condensed consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles. 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 and the related reserves, accrued research and development expenses, 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.

Our critical accounting estimates include: revenue recognition, investments, inventory and the related reserves, accrued research and development expenses, income taxes, and stock-based compensation. There have been no material changes to our critical accounting estimates disclosures included in our 2023 Annual Report.

Results of Operations for the Three Months Ended March 31, 2024 and 2023

Net Product Sales

For the three months ended March 31, 2024 and March 31, 2023, net product sales were $34.7 million and $29.6 million, respectively.

Net Product Sales – Acute Care

For the three months ended March 31, 2024 and March 31, 2023, net product sales of ZYNRELEF were $5.0 million and $3.5 million, respectively. For the three months ended March 31, 2024 and March 31, 2023, net product sales of APONVIE were $0.5 million and $0.3 million, respectively. The increase in net product sales for both ZYNRELEF and APONVIE is attributed to an increase in the units sold in 2024 as compared to 2023.

Net Product Sales – Oncology Care

For the three months ended March 31, 2024 and March 31, 2023, net product sales of CINVANTI were $25.6 million and $22.8 million, respectively. For the three months ended March 31, 2024 and March 31, 2023, net product sales of SUSTOL were $3.6 million and $3.0 million, respectively. The increase in net product sales for both CINVANTI and SUSTOL is attributed to an increase in the units sold in 2024 as compared to 2023.

Cost of Product Sales

For the three months ended March 31, 2024 and March 31, 2023, cost of product sales was $8.4 million and $16.9 million, respectively. 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 three months ended March 31, 2023, cost of product sales also included charges of $5.3 million, resulting primarily from the write-off of short-dated ZYNRELEF inventory. There were no charges related to the write-off of inventory during the three months ended March 31, 2024. The remaining decrease in cost of product sales is attributed to a decrease in cost per units for CINVANTI and ZYNRELEF, as large-scale manufacturing was validated and approved in late 2022.

Research and Development Expense

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


	Three Months Ended March 31,
	2024		2023
ZYNRELEF-related costs	$	636	$	2,156
CINVANTI-related costs		471		824
APONVIE-related costs		202		693
SUSTOL-related costs		90		281
Personnel costs and other expenses		2,508		3,147
Stock-based compensation expense		701		1,736
Total research and development expense	$	4,608	$	8,837

For the three months ended March 31, 2024 and March 31, 2023, research and development expense was $4.6 million and $8.8 million, respectively. The decrease in research and development expense was primarily due to our decreased headcount and related costs as a result of the restructuring implemented in 2023, as well as a decrease in non-cash, stock-based compensation expense. The decrease is also due to decreases in costs related to ZYNRELEF and CINVANTI, as large-scale manufacturing was approved in 2022 and APONVIE as a result of the product becoming commercially available in March 2023.

General and Administrative Expense

For the three months ended March 31, 2024 and March 31, 2023, general and administrative expense was $15.0 million and $15.8 million, respectively. The decrease was primarily due to our decreased headcount and related costs as a result of the restructuring implemented in 2023.

Sales and Marketing Expense

For the three months ended March 31, 2024 and March 31, 2023, sales and marketing expense was $11.4 million and $21.2 million, respectively. The decrease was primarily due to our decreased headcount and related costs as a result of the restructuring implemented in 2023.

Other Income, Net

For the three months ended March 31, 2024 and March 31, 2023, other income, net was $1.6 million and $0.3 million, respectively. The increase is primarily attributed to a one time settlement gain contingency related to a legal dispute, during the three months ended March 31, 2024.

Restructuring Plans

See Note 8 to the condensed consolidated financial statements included in Item 1 of this Quarterly Report on Form 10-Q for discussion of the June 2023 Reorganization.

Liquidity and Capital Resources

The Company's short-term and long-term liquidity requirements primarily arise from funding (i) sales and marketing expenses, (ii) general and administrative expenses including salaries, bonuses and commissions, (iii) working capital requirements, and (iv) research and development expenses, and (v) payments related to our outstanding convertible notes. As of March 31, 2024, we had cash, cash equivalents and short-term investments of $71.5 million. Based on our current operating plan and projections, management believes that the Company's cash, cash equivalents and short-term investments will be sufficient to meet the Company's anticipated cash requirements for a period of at least the next twelve months from the date this Quarterly Report on Form 10-Q is filed with the SEC. Our future cash requirements and the adequacy of our available funds will depend on many factors, primarily including our ability to generate revenue and the scope and costs of our commercial and research and development activities.

Our net loss for the three months ended March 31, 2024 and March 31, 2023 was $3.2 million, or $0.02 per share, and $32.8 million, or $0.27 per share, respectively.

Our net cash used in operating activities for the three months ended March 31, 2024 and March 31, 2023 was $9.5 million, compared to $24.9 million. The decrease in net cash used in operating activities was primarily due to a decrease in net loss as a result of decreases in operating spend, partially offset by changes in working capital, specifically accounts receivable due to timing of collections, inventory as a result of write-offs incurred during Q1 2023 which did not reoccur during Q1 2024, accounts payable due to timing of payments and accrued payroll and employee liabilities due to reduced headcount.

Our net cash provided by investing activities for the three months ended March 31, 2024 and March 31, 2023 was $1.3 million, compared to $36.8 million. The decrease in cash provided by investing activities was primarily due to net maturities of short-term investments of $37.1 million for the three months ended March 31, 2023 compared to $1.3 million for the three months ended March 31, 2024.

Our net cash provided by financing activities for the three months ended March 31, 2024 was $0.01 million, compared to net cash used in financing activities of $0.2 million for the same period in 2023.

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

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Not required for smaller reporting companies.

ITEM 4. CONTROLS AND PROCEDURES

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports, filed or submitted under the Exchange Act, is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, including, without limitation, controls and procedures designed to ensure that information required to be disclosed in such reports is accumulated and communicated to our management, including our principal executive officer, principal financial officer, and principal accounting officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable and not absolute assurance of achieving the desired control objectives. In reaching a reasonable level of assurance, management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. In addition, the design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, a control may become inadequate because of changes in conditions or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

Our management, with the participation of our principal executive officer, principal financial officer and principal accounting officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act), as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on the foregoing, our principal executive officer, principal financial officer, and principal accounting officer concluded that our disclosure controls and procedures were effective as of such time.

There were no changes in our internal control over financial reporting that occurred during the quarter covered by this Quarterly Report on Form 10-Q that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

Except as discussed below, there are no material changes from the legal proceedings previously disclosed in our most recently filed Annual Report on Form 10-K for the year ended December 31, 2023.

On August 4, 2023, the Company received a Notice Letter from Mylan Pharmaceuticals Inc. (“Mylan”) advising that Mylan had submitted an ANDA to the FDA seeking approval to manufacture, use or sell a generic version of CINVANTI (“Mylan’s ANDA for a generic version of CINVANTI”) in the U.S. prior to the expiration of U.S. Patent Nos.: 9,561,229, 9,808,465, 9,974,742, 9,974,793, 9,974,794, 10,500,208, 10,624,850, 10,953,018, and 11,173,118 (the “CINVANTI Patents”), which are listed in the FDA’s Approved Drug Products with Therapeutic Equivalence Evaluations (the “Orange Book”). The Notice Letter alleges that the CINVANTI Patents are invalid, unenforceable and/or will not be infringed by the commercial manufacture, use or sale of the generic product described in Mylan’s ANDA for a generic version of CINVANTI. On September 15, 2023, the Company filed a complaint for patent infringement of the CINVANTI Patents against Mylan in the U.S. District Court for the District of Delaware in response to the filing of Mylan’s ANDA for a generic version of CINVANTI. The complaint seeks, among other relief, equitable relief enjoining Mylan from infringing the CINVANTI Patents. The parties are currently conducting fact discovery. A five-day bench trial is scheduled for May 19, 2025. The Company intends to vigorously enforce its intellectual property rights relating to CINVANTI. As a result of filing our complaint for patent infringement, the FDA may not approve Mylan’s ANDA for a generic version of CINVANTI until the earlier of February 4, 2026 or resolution of the litigation.

On December16, 2023, the Company received a Notice Letter from Mylan advising that Mylan had submitted an ANDA to the FDA seeking approval to manufacture, use or sell a generic version of APONVIE in the U.S. (“Mylan’s ANDA for a generic version of APONVIE”) prior to the expiration of the APONVIE patents, which are listed in the Orange Book. The Notice Letter alleges that the APONVIE Patents are invalid, unenforceable and/or will not be infringed by the commercial manufacture, use or sale of the generic product described in Mylan’s ANDA for a generic version of APONVIE. On January 11, 2024, the Company filed a complaint for patent infringement of the APONVIE Patents against Mylan in the U.S. District Court for the District of Delaware in response to Mylan filing an ANDA for a generic version of APONVIE. The complaint seeks, among other relief, equitable relief enjoining Mylan from infringing the APONVIE Patents. On January 26, 2024, the Court consolidated this litigation concerning Mylan’s ANDA for a generic version of APONVIE with the previously-filed litigation concerning Mylan’s ANDA for a generic version of CINVANTI. Accordingly, a five-day bench trial is scheduled for May 19, 2025. The Company intends to vigorously enforce its intellectual property rights relating to APONVIE. As a result of filing our complaint for patent infringement, the FDA may not approve Mylan’s ANDA for a generic version of APONVIE until the earlier of June 16, 2026 or resolution of the litigation.

On December 12, 2023, the Company received a Notice Letter from Slayback Pharma LLC (“Slayback”) advising that Slayback had submitted an NDA under Section 505(b)(2) of the Federal Food, Drug, and Cosmetic Act to the FDA seeking approval to manufacture, use or sell a generic version of CINVANTI in the U.S. (“Slayback’s NDA”) prior to the expiration of the CINVANTI patents, which are listed in the Orange Book. The Notice Letter alleges that the CINVANTI Patents are invalid, unenforceable and/or will not be infringed by the commercial manufacture, use or sale of the generic product described in Slayback’s NDA. On January 24, 2024, the Company filed a complaint for patent infringement of the CINVANTI Patents against Slayback and a related entity in the U.S. District Court for the District of New Jersey in response to Slayback’s NDA filing. The complaint seeks, among other relief, equitable relief enjoining Slayback from infringing those patents. The parties are currently providing their pleadings for the case. The Company intends to vigorously enforce its intellectual property rights relating to CINVANTI. As a result of filing our complaint for patent infringement, the FDA may not approve Slayback's NDA until the earlier of June 12, 2026 or resolution of the litigation.

CO-PROMOTION AGREEMENT

THIS CO-PROMOTION AGREEMENT (the “Agreement”) is dated this 5th day of January, 2024, but effective as of January 1, 2024 (the “Effective “Date”) by and between Heron Therapeutics, Inc., a Delaware corporation (hereinafter called “Heron”) and Crosslink Network, LLC, a Georgia limited liability company (hereinafter called “Co-Promoter”) (Heron and Co-Promoter sometimes hereinafter referred to individually as a “Party” and collectively as the “Parties”).

WITNESSETH:

WHEREAS, the Parties hereto desire to enter into this Agreement upon the terms hereinafter set forth so as to promote the sale of ZYNRELEF® (bupivacaine and meloxicam) extended-release solution (the “Product”) for all of the Product’s current and future FDA approved indications involving surgical procedures performed within the Territory (as hereinafter defined). For purposes hereof, the term “Product” includes all subsequent FDA approved enhancements or improvements made by Heron to the Product including without limitation enhancements and improvements to the method of dosing or delivery of the Product (e.g., Heron’s proposed pre-filled syringe delivery mechanism).

NOW, THEREFORE, in consideration of the premises and the mutual covenants herein contained and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties hereby covenant and agree as follows:

APPOINTMENT OF CO-PROMOTER

For the Term (as hereinafter defined) of this Agreement, Heron appoints Co-Promoter as its exclusive co-promoter (with the exception of sales personnel directly employed by Heron and with respect to geographic regions where Co-Promoter has not granted rights or intends to grant rights prior to the first anniversary of this Agreement to any of its affiliated Sub-Promoters referenced in Section 2.02 below) for the sale of the Product within the United States (the “Territory”) for all of the Product’s current and future FDA approved indications and Co-Promoter hereby accepts this appointment, all subject to the terms and conditions of this Agreement.

CO-PROMOTER’S RESPONSIBILITIES

2.01

Co-Promoter agrees to act, through itself and its Sub-Promoters (as defined in Section 2.02 below), as the exclusive promoter of the Product within the Territory; to diligently pursue a sales program to promote and sell the Product; and to develop and increase the demand for the Product. Co-Promoter also agrees to (a) meet with Heron to jointly prepare a quarterly business and promotion plan at least [***] prior to start of each calendar quarter period commencing on April 1, 2024, (b) provide periodic information

updates on market conditions and trends relating to the Product and forecasts on potential business opportunities, (c) participate with Heron in trade shows in the Territory, and (d) provide for transmission of sales bulletins, advertising literature and other information (as provided by Heron) to actual or potential customers of Heron. Such responsibilities shall be accomplished through prompt and efficient customer and potential customer services, the provision of adequate and timely sales effort, and the maintenance of a close working relationship with Heron’s management.

2.02

Co-Promoter shall be permitted to engage the services of independent contractors (“Sub-Promoters”) to promote the sale of the Product with respect to portions of the Territory, but only after each such Sub-Promoter has been presented to Heron for review and approval, which approval shall not be unreasonably withheld. In facilitating Heron’s review of any potential Sub-Promoter, Co-Promoter shall provide Heron with the proposed form of contract between Co-Promoter and Sub-Promoter containing, among other things, all material economic terms between Co-Promoter and the potential Sub-Promoter. Unless Co-Promoter and Heron agree otherwise in writing, Co-Promoter shall remain exclusively responsible for the servicing of all Sub-Promoter accounts and for all of the actions of each such Sub-Promoter; provided, however, notwithstanding any provision in this Agreement to the contrary, Co-Promoter may cure any potential breach of this Agreement resulting directly from the actions of a Sub-Promoter by either terminating its agreement with such Sub-Promoter within [***] of receiving notice of such breach from Heron or taking such other action with such Sub-Promoter as is acceptable to Heron to avoid breach or termination of this Agreement. Co-Promoter shall remain exclusively responsible for compensating any such Sub-Promoter. Although Heron shall have to right at any time during the Term to engage non-employed personnel to promote the Products with respect to geographic regions within the Territory that are not covered by Co-Promoter and/or any of its Sub-Promoters, Heron shall only be permitted to do so within [***] following the Effective Date in the manner provided in Section 1 above, and with respect to any such engagement desired by Heron following the first anniversary of the Effective Date, only after Heron has provided at least [***] advance written notice to Co-Promoter of the territory to be covered by such engagement to ensure that such engagement does not conflict with any pre-existing agreements between Co-Promoter and/or any of its Sub-Promoters or interfere with any then ongoing discussions between Co-Promoter and any prospective Sub-Promoter(s) relating to the grant of rights to promote the Products with respect to any portion of such territory to be covered by such engagement.

2.03

Co-Promoter shall be responsible for all aspects of the management of any sales representatives retained by Co-Promoter, including, without limitation, all matters relating to the recruiting, hiring, supervising, training (except as otherwise provided herein), equipping/outfitting (including vehicle leasing, laptops, sample bags and similar equipment), reimbursement for expenses and compensating (including compensation, incentives, benefits, supplies, discretionary spending funds, equipment, travel, food and lodging) such sales representatives. All employees and agents of Co-Promoter are its sole employees and agents and nothing contained herein shall be construed to make them the employees or agents of Heron. Notwithstanding the designation of “Co-Promoter”, it is understood that Co-Promoter is an independent

-2-

contractor and not an employee or agent of Heron and that nothing herein contained shall be deemed to constitute the Parties as partners or joint venturers and that there are no rights conferred upon Co-Promoter by this Agreement to contract for, or on behalf of, or otherwise obligate Heron, in any manner.

2.04

Co-Promoter will and shall require any Sub-Promoter to maintain complete and accurate records of all activities carried out by Co-Promoter or Sub-Promoter, as the case may be, and each of their respective employees and representatives relating to the performance of Co-Promoter’s services hereunder for the duration of Term and for three (3) years thereafter.

6.02

Co-Promoter covenants and agrees, and will require each of its Sub-Promoters to covenant and agree in writing, that, during the Term of this Agreement and for [***] following expiration or termination of this Agreement (or in the case of a Sub-Promoter, during the term of Sub-Promoter’s agreement with Co-Promoter and for [***] following expiration or termination of such agreement with Co-Promoter), Co-Promoter or each such Sub-Promoter, as the case may be, will not, within the Territory (or in the case of a Sub-Promoter, within the territory assigned to such Sub-Promoter pursuant to its agreement with Co-Promoter), without the express written consent of Heron: (a) promote, sell or distribute any Competing Product (as defined below) of any other person, corporation or other entity which is in competition with the Product it is representing hereunder or (b) act as a promoter, distributor or agent for any other person, corporation, or other entity with respect to any Competing Product which is in competition with the Product it is representing hereunder. Co-Promoter acknowledges and agrees that the provisions of this Section 6.02 are a key inducement for Heron to enter into this Agreement, and any breach of such provisions by Co-Promoter or any Sub-Promoter would constitute a material breach of this Agreement; provided, however, as stated in Section 2.02 above, Co-Promoter may cure any potential material breach of this Section 6.02 resulting directly from the actions of a Sub-Promoter by either terminating its agreement with such Sub-Promoter within thirty (30) days of receiving notice of such breach from Heron or taking such other action with such Sub-Promoter as is acceptable to Heron to avoid breach or termination of this Agreement; and provided, further, however, any breach of this Section 6.02 relating to the actions of a Sub-Promoter during the twelve (12) month period following the termination of such Sub-Promoter’s agreement with Co-Promoter shall not be deemed a breach of this Agreement if Co-Promoter is complying with its obligations under Section 6.04 below. In addition and notwithstanding any provision in this Agreement to the contrary, in no event shall Co-Promoter be deemed in material breach of this Section 6.02 if Co-Promoter is required pursuant to its relationship with [***] to begin selling any Competing Product in the Territory; however, in such event, each of Co-Promoter and Heron shall have the right to elect to terminate this Agreement pursuant to the provisions

of Section 8.02(g) below (in the case of termination by Co-Promoter) or Section 8.02(h) below (in the case of termination by Heron).

6.03

Co-Promoter agrees that any breach of this Article 6 by Co-Promoter or its Sub-Promoters may cause irreparable harm to Heron and that damages would be difficult to calculate and, therefore, specifically agrees that the provisions of this Article 6 may be enforced by injunctive relief and that Heron may seek the same in any court of competent jurisdiction; provided, however, nothing herein shall be construed as prohibiting Heron from also pursuing any other remedies available at law or in equity, including the recovery of damages.

All actions on the part of such Party, the board of directors or managers of such Party and the equity holders or members of such Party necessary for (a) the authorization, execution, delivery and performance by such Party of this Agreement, and (b) the consummation of the transactions contemplated hereby, have been duly taken. This Agreement is legally valid and binding on such Party, enforceable against such Party in accordance with its terms (except in all cases as such enforceability may in the future be limited by applicable bankruptcy, insolvency, reorganization, moratorium, or similar

-14-

laws affecting the enforcement of creditors’ rights generally and except that the availability of the equitable remedy of specific performance or injunctive relief is subject to the discretion of the court before which any proceeding may be brought);

9.01.3

None of the execution and delivery of this Agreement, the consummation of the transactions provided for herein or contemplated hereby, or the fulfillment by such Party of the terms hereof or thereof, will (with or without notice or passage of time or both): (a) conflict with or result in a breach of any provision of the certificate of incorporation, by-laws, operating agreement or other governing documents of such Party, (b) result in a default, constitute a default under, give rise to any right of termination, cancellation or acceleration, or require any consent or approval (other than approvals that have been obtained) under any of the terms, conditions, or provision of any material note, bond, mortgage, indenture, loan, arrangement, license, agreement, lease or other instrument or obligation to which such Party is a party or by which its assets may be bound, or (c) violate any law or regulation applicable to such Party or any of its assets;

9.01.4

There is no action, suit, proceeding or investigation pending or, to such Party’s knowledge, currently threatened, against such Party that questions the validity of this Agreement or the right of such Party to enter into this Agreement, or to consummate the transactions contemplated hereby, nor does such Party have knowledge that there is any basis for the foregoing. Such Party is not a Party or subject to the provisions of any order, writ, injunction, judgment or decree of any Governmental Authority, which would adversely affect its rights or obligations hereunder or the transactions contemplated hereby.

-15-

9.02

In addition to those representations and warranties of Co-Promoter set forth above, Co-Promoter further represents, warrants and covenants to Heron as follows:

9.02.1

Co-Promoter has, and will at all times during the Term of this Agreement have, in all material respects, the requisite expertise, experience and skill to promote the Product and that it shall cause the services to be performed hereunder by all affiliates, employees and/or agents or Sub-Promoters of Co-Promoter to be performed, in all material respects, in a competent, efficient and professional manner; and

9.02.2

Neither Co-Promoter nor any person employed or retained by Co-Promoter or any Sub-Promoter in connection with any work to be performed for or on behalf of Heron has been debarred under Section 306(a) or (b) of the Food Drug and Cosmetic Act, 21 U.S.C. § 301 et seq. as it may be amended from time to time and no debarred person will in the future be employed by Co-Promoter or any Sub-Promoter in connection with any work to be performed for or on behalf of Heron. If at any time after execution of this Agreement, Co-Promoter becomes aware that Co-Promoter or any person employed by Co-Promoter or any Sub-Promoter in connection with any work to be performed for or on behalf of Heron becomes or is in the process of being debarred, Co-Promoter shall so notify Heron immediately in writing and immediately take steps to prevent such person from performing any of the services contemplated by this Agreement, it being understood that if appropriate and prompt disciplinary action is taken and there is no material adverse effect on Heron or its operations as a result of such person’s actions, then Co-Promoter shall be deemed to have cured any potential breach of this Agreement caused by such person’s actions.

9.03

EXCEPT AS OTHERWISE EXPRESSLY PROVIDED IN THIS AGREEMENT, NO PARTY MAKES ANY OTHER REPRESENTATIONS OR WARRANTIES, INCLUDING FITNESS FOR PURPOSE INTENDED OR MERCHANTABILITY, WHETHER EXPRESS OR IMPLIED.

10.

DISPUTES

Any dispute, controversy or claim initiated by either Party arising out of, resulting from or relating to this Agreement, or the performance by either Party of its obligations under this Agreement (other than bona fide third party actions or proceedings filed or instituted in an action or proceeding by a third party against a Party), whether before or after termination of this Agreement, shall be finally resolved by binding arbitration. Any such arbitration shall be conducted under the Commercial Arbitration Rules of the American Arbitration Association by a panel of three arbitrators appointed in accordance with such rules with the arbitration taking place in North Carolina. The method and manner of discovery in any such arbitration proceeding shall be governed by the laws of the State of Delaware. The arbitrators shall have the authority to grant injunctions and/or specific performance and to allocate between the Parties the costs of arbitration in such equitable manner as they determine. Judgment upon the award so

-16-

rendered may be entered in any court having jurisdiction or application may be made to such court for judicial acceptance of any award and an order of enforcement, as the case may be. In no event shall a demand for arbitration be made after the date when institution of a legal or equitable proceeding based upon such claim, dispute or other matter in question would be barred by the applicable statute of limitations. Notwithstanding the foregoing, either Party shall have the right, without waiving any right or remedy available to such Party under this Agreement or otherwise, to seek and obtain from any court of competent jurisdiction any interim or provisional relief that is necessary or desirable to protect the rights or property of such Party, pending the selection of the arbitrators hereunder or pending the arbitrators’ determination of any dispute, controversy or claim hereunder.

11.

GENERAL PROVISIONS

11.01

No failure or delay of one of the Parties to insist upon strict performance of any of its rights or powers under this Agreement shall operate as a waiver thereof, nor shall any other single or partial exercise of such right or power preclude any other further exercise of any rights or remedies provided by law.

11.02

It is expressly recognized by Heron and Co-Promoter that this Agreement is based upon Heron’s reliance on senior management of Co-Promoter and, therefore, Co-Promoter may not assign or transfer this Agreement, or delegate its obligations under this Agreement, without prior written approval of Heron. Any change of control, merger, spin-off or other corporate reorganization of or involving Co-Promoter shall constitute an assignment for purposes of this Section 11.02. Heron may assign its interest in this Agreement to an Affiliate or in connection with a merger or sale of substantially all of its business or that portion of its business pertaining to the subject matter of this Agreement, whether by merger, sale of stock, sale or licensing of assets or otherwise. The term “Affiliate” as used in this Agreement means, with respect to a Party, any other natural person or legal entity, including, without limitation, any business, corporation, company, association, limited liability company, partnership, limited partnership, joint venture, trust or other legal entity (each, a “Person”), that is now, or in the future, directly or indirectly Controlling, Controlled by or under common Control with such Party, where “Control” and derivative terms mean the possession, directly, or indirectly, of the power to direct or cause the direction of the management and policies of a Party or a Person, whether through the ownership of voting securities, by contract or otherwise. Notwithstanding the foregoing and except as otherwise stated in Section 2.02, Co-Promoter may engage the services of independent contractors to promote the sale of Product with respect to portions of the Territory, but only after each such independent contractor has been presented to Heron for approval, which approval shall not be unreasonably withheld.

11.03

THIS AGREEMENT, INCLUDING EXHIBITS A, B AND C ATTACHED HERETO AND INCORPORATED HEREIN AS AN INTEGRAL PART OF THIS AGREEMENT, CONSTITUTES THE ENTIRE AGREEMENT OF THE PARTIES WITH RESPECT TO THE SUBJECT MATTER HEREOF, AND SUPERSEDES ALL PREVIOUS AGREEMENTS BY AND BETWEEN HERON AND CO-PROMOTER

-17-

AS WELL AS ALL PROPOSALS, ORAL OR WRITTEN, AND ALL NEGOTIATIONS, CONVERSATIONS OR DISCUSSIONS HERETOFORE HAD BETWEEN THE PARTIES RELATED TO THIS AGREEMENT. CO-PROMOTER ACKNOWLEDGES THAT IT HAS NOT BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY ANY REPRESENTATIONS OR STATEMENTS, ORAL OR WRITTEN, NOT EXPRESSLY CONTAINED HEREIN.

11.04

No modification of this Agreement shall be binding on either Party unless it is in writing and signed by both Parties. If any provision of this Agreement is or becomes invalid, illegal or unenforceable in any respect, it shall be ineffective to the extent of such invalidity, illegality or unenforceability and the remaining provisions of this Agreement shall remain in effect. If the terms and conditions of this Agreement are materially altered as a result of the applicability of this Section 11.04, the Parties shall negotiate such altered terms and conditions so as to achieve the original intent of the Parties to the extent legally permissible.

11.05

No liability shall result from delay in performance or nonperformance caused by extraordinary circumstances beyond the reasonable control of the Party affected, including, but not limited to, acts of God, fire, flood, war, embargo, terrorism, pandemic, any United States government regulation, labor trouble or shortage thereof or inability to obtain material equipment or transport (each, a “Force Majeure Event”). In the event a Party is unable to perform its obligations under this Agreement for more than [***] because of any Force Majeure Event, the other Party may terminate this Agreement, in whole but not in part, upon written notice to such Party. In the event Co-Promoter’s performance hereunder is delayed by a Force Majeure Event, Heron’s compensation obligations under this Agreement shall be suspended until Co-Promoter’s performance resumes, except with respect to fees incurred prior to Co-Promoter’s performance being so delayed by the applicable Force Majeure Event.

11.06

All notices and other communications given or made pursuant to this Agreement by a Party shall be in writing and shall be deemed effectively given upon the earlier of actual receipt by the other Party or: (a) personal delivery to the Party to be notified, (b) when sent, if sent by electronic mail during normal business hours of the recipient, and if not sent during normal business hours, then on the next business day, (c) five (5) days after having been sent by registered or certified mail, return receipt requested, postage prepaid, or (d) one (1) business day after the business day of deposit with a nationally recognized overnight courier, freight prepaid, specifying next business day delivery, with written verification of receipt. Any notice required pursuant to this Agreement shall be in writing and shall be sent to the other Party as follows:

Neither Party may publicly disclose the existence or terms or any other matter of fact regarding this Agreement and any ancillary agreements without the prior written consent of the other Party, which consent shall not be unreasonably withheld or delayed; provided, however, that either Party may make such a disclosure and provide a copy of this Agreement and any ancillary agreements to the extent required by applicable law or by the requirements of any nationally recognized securities exchange, quotation system or over-the-counter market on which such Party has its securities listed or traded. In the event that such disclosure is required as aforesaid, the disclosing Party shall make reasonable efforts to provide the other Party with notice beforehand and to coordinate with the other Party with respect to the timing of any such disclosure. Notwithstanding the foregoing, either Party may disclose to a third party the existence or terms or any other matter of fact regarding this Agreement and any ancillary agreements and provide a copy of this Agreement and any ancillary agreements without the prior written consent of the other Party: (a) pursuant to, and in accordance with, any existing contractual

-19-

obligations with such party; or (ii) if such third party is an investor or a prospective investor, purchaser, partner, lender, or other potential financing source, Sub-Promoter or potential Sub-Promoter (or a representative of any of the foregoing) who is obligated to keep such information confidential.

11.08

Except as set forth in Sections 2.12 and 3.03, the Parties do not intend this Agreement to create any third party beneficiaries.

11.09

Neither Heron nor Co-Promoter (which for the purposes of this Article 11 shall include their respective Affiliates, directors, managers, officers, employees, consultants, equity holders, representatives and agents) shall have any liability to the other for any punitive damages, special, consequential or indirect damages, relating to or arising from the loss of commercial or business opportunity, revenue or profit, in connection with or arising out of this Agreement, even if such damages may have been foreseeable; provided that such limitation shall not apply in the case of (a) fraud, (b) gross negligence or intentional misconduct, (c) any damages (including, without limitation, the types enumerated in this Section 11.09) claimed by or paid to a third party in connection with a third party claim, or (d) breach of Articles 6, 7, or 9.

11.10

Each Party shall act in good faith in its performance of this Agreement and shall: (a) not unreasonably delay or withhold the giving of any consent, decision or approval that is either requested or reasonably required by the other Party in order to perform its responsibilities and/or obligations under this Agreement; and (b) do such other acts and things the other Party may reasonably request for the purpose of carrying out the intent of this Agreement.

11.11

In performing its obligations under this Agreement, Co-Promoter and its Sub-Promoters, Affiliates, employees and agents (a) shall not offer to make, make, promise, authorize or accept any payment or giving anything of value, including but not limited to bribes, either directly or indirectly to any public official, regulatory authority or anyone else for the purpose of influencing, inducing or rewarding any act, omission or decision in order to secure an improper advantage, or obtain or retain business and (b) shall comply with all applicable anti-corruption and anti-bribery laws and regulations; provided, however, in no event shall the foregoing language be interpreted to prohibit any actions undertaken by Co-Promoter and its Sub-Promoters, Affiliates, employees and agents that are in compliance with the PhRMA Code. Co-Promoter and its Sub-Promoters, Affiliates, employees, agents, consultants and permitted subcontractors shall not make any payment or provide any gift to a third party in connection with Co-Promoter’s performance of its obligations hereunder except as may be expressly permitted in this Agreement without first identifying the intended third-party recipient to Heron and obtaining Heron’s prior written approval. Co-Promoter shall notify Heron immediately upon becoming aware of any breach of obligations under this Section. Co-Promoter (and any individual(s) provided by Co-Promoter to perform Services hereunder, including Sub-Promoters) shall participate in any anti-corruption training reasonably required by Heron.

11.12

Equal Opportunity Compliance. This contractor and subcontractor shall abide by the requirements of 41 CFR 60-1.4(a), 60-300.5(a) and 60-741.5(a). These regulations prohibit discrimination against qualified individuals based on their status as protected veterans or individuals with disabilities, and prohibit discrimination against all individuals based on their race, color, religion, sex, sexual orientation, gender identity or national origin. Moreover, these regulations require that covered prime contractors and subcontractors take affirmative action to employ and advance in employment individuals without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, disability or veteran status.

11.13

This Agreement may be executed in any number of counterparts, in the original or by electronic means (including, without limitation, via DocuSign or by exchange of electronic signature pages, including .PDF), each of which will be deemed an original and all of which taken together will be deemed to constitute one and the same instrument.

Basis of Presentation	2. Basis of Presentation The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and the requirements of the SEC for interim reporting. Accordingly, since they are interim statements, they do not include all of the information and disclosures required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three months ended March 31, 2024 are not necessarily indicative of the results that may be expected for other quarters or the year ending December 31, 2024. The condensed consolidated balance sheet as of December 31, 2023 has been derived from the audited financial statements as of that date. For more complete financial information, these condensed consolidated financial statements and the notes thereto should be read in conjunction with the audited financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2023, which was filed with the SEC on March 12, 2024. Reclassification of Certain Expenses The condensed consolidated statements of operations and comprehensive loss for the three months ended March 31, 2023 reflects reclassification of certain expenses from research and development to general and administrative expenses to align with the Company's presentation for the three months ended March 31, 2024 as a result of the restructuring implemented in 2023, the realignment of the Company's departments and the function of the expenses incurred. This presentation results in no change to total operating expenses, loss from operations or net loss and no pro forma financial information is necessary.
