NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

NOTE 1—DESCRIPTION OF BUSINESS

Pacira BioSciences, Inc. and its subsidiaries (collectively, the “Company” or “Pacira”) is the therapeutic area leader in non-opioid pain management with a stated corporate mission of providing non-opioid pain management options to as many patients as possible and redefining the role of opioids for rescue therapy only. The Company’s long-acting, local analgesic, EXPAREL® (bupivacaine liposome injectable suspension), was commercially launched in the United States, or U.S., in April 2012 and approved in select European countries and the United Kingdom, or U.K., in November 2021. EXPAREL utilizes the Company’s proprietary multivesicular liposome, or pMVL, drug delivery technology that encapsulates drugs without altering their molecular structure and releases them over a desired period of time. In November 2021, the Company acquired Flexion Therapeutics, Inc., or Flexion (the “Flexion Acquisition”), and added ZILRETTA® (triamcinolone acetonide extended-release injectable suspension) to its product portfolio. ZILRETTA is the first and only extended-release, intra-articular (meaning in the joint) injection indicated for the management of osteoarthritis, or OA, knee pain. In April 2019, the Company added iovera°® to its commercial offering with the acquisition of MyoScience, Inc., or MyoScience (the “MyoScience Acquisition”). The iovera° system is a handheld cryoanalgesia device used to deliver a precise, controlled application of cold temperature to targeted nerves.

Pacira is subject to risks common to companies in similar industries and stages, including, but not limited to, competition from larger companies, reliance on revenue from three products, reliance on a limited number of wholesalers, reliance on a limited number of manufacturing sites, new technological innovations, dependence on key personnel, reliance on third-party service providers and sole source suppliers, protection of proprietary technology, compliance with government regulations and risks related to cybersecurity.

The Company is managed and operated as a single business focused on the development, manufacture, marketing, distribution and sale of non-opioid pain management and regenerative health solutions. The Company is managed by a single management team, and consistent with its organizational structure, the Chief Executive Officer—who is the Company’s chief operating decision maker—manages and allocates resources at a consolidated level. Effective January 2, 2024, the Company appointed a new Chief Executive Officer. Consistent with the Company’s predecessor chief operating decision maker, the Company views its business as one reportable operating segment to evaluate its performance, allocate resources, set operational targets and forecast its future financial results.

NOTE 2—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation and Principles of Consolidation

These interim condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America, or GAAP, and in accordance with the rules and regulations of the United States Securities and Exchange Commission (the “SEC”), for interim reporting. Pursuant to these rules and regulations, certain information and footnote disclosures normally included in complete annual financial statements have been condensed or omitted. Therefore, these interim condensed consolidated financial statements should be read in conjunction with the audited annual consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 (the “2023 Annual Report”).

The condensed consolidated financial statements at June 30, 2024, and for the three and six-month periods ended June 30, 2024 and 2023, are unaudited, but include all adjustments (consisting of only normal recurring adjustments) which, in the opinion of management, are necessary to present fairly the financial information set forth herein in accordance with GAAP. The condensed consolidated balance sheet at December 31, 2023 is derived from the audited consolidated financial statements included in the Company’s 2023 Annual Report. The condensed consolidated financial statements as presented reflect certain reclassifications from previously issued financial statements to conform to the current year presentation. The accounts of wholly-owned subsidiaries are included in the condensed consolidated financial statements. Intercompany accounts and transactions have been eliminated in consolidation.

The results of operations for these interim periods are not necessarily indicative of results that may be expected for any other interim periods or for the full year.

Concentration of Major Customers

The Company sells EXPAREL through a drop-ship program under which orders are processed through wholesalers (including AmerisourceBergen Health Corporation, Cardinal Health, Inc. and McKesson Drug Company), but shipments of the product are sent directly to individual accounts, such as hospitals, ambulatory surgery centers and individual physicians. The table below includes the percentage of revenues comprised by the Company’s three largest wholesalers in each period presented:


	Three Months Ended June 30,		Six Months Ended June 30,
	2024	2023	2024	2023
Largest wholesaler	34%	33%	35%	32%
Second largest wholesaler	22%	24%	23%	24%
Third largest wholesaler	19%	20%	19%	21%
Total	75%	77%	77%	77%

Recent Accounting Pronouncements Not Adopted as of June 30, 2024

In November 2023, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, 2023-07, Segment Reporting (Topic 280), Improvements to Reportable Segment Disclosures. The ASU amendment improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses on an interim and annual basis. The new segment disclosure requirements apply for entities with a single reportable segment. The ASU’s amendments are effective for fiscal years beginning after December 15, 2023 and interim periods thereafter, with early adoption permitted. The ASU amendment will require adoption on a retrospective basis. The Company is currently evaluating the impact of adopting ASU 2023-07 on its consolidated financial statements.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740), Improvements to Income Tax Disclosures. The ASU amendment addresses investor requests for more transparency about income tax information through improvements to income tax disclosures primarily related to the rate reconciliation and income taxes paid information. The ASU’s amendments are effective for fiscal years beginning after December 15, 2024 and may be adopted on a prospective or retrospective basis. The Company is currently evaluating the impact of adopting ASU 2023-09 on its consolidated financial statements.

Royalty revenues are related to a collaborative licensing agreement from the sale of its bupivacaine liposome injectable suspension for veterinary use. The Company does not consider revenue from sources other than sales of EXPAREL and ZILRETTA to be material sources of its consolidated revenue. As such, the following disclosure is limited to revenue associated with net product sales of EXPAREL and ZILRETTA.

Net Product Sales

The Company sells EXPAREL through a drop-ship program under which orders are processed through wholesalers based on orders of the product placed by end-users, namely hospitals, ambulatory surgery centers and healthcare provider offices. EXPAREL is delivered directly to the end-user without the wholesaler ever taking physical possession of the product. The Company primarily sells ZILRETTA to specialty distributors and specialty pharmacies, who then subsequently resell ZILRETTA to physicians, clinics and certain medical centers or hospitals. The Company also contracts directly with healthcare providers and intermediaries such as group purchasing organizations, or GPOs. Product revenue is recognized when control of the promised goods are transferred to the customer, in an amount that reflects the consideration the Company expects to be entitled to in exchange for transferring those goods. EXPAREL and ZILRETTA revenue is recorded at the time the products are transferred to the customer.

Revenues from sales of products are recorded net of returns allowances, prompt payment discounts, service fees, government rebates, volume rebates and chargebacks. These reserves are based on estimates of the amounts earned or to be claimed on the related sales. These amounts are treated as variable consideration, estimated and recognized as a reduction of the transaction price at the time of the sale, using the most likely amount method, except for returns, which is based on the expected

Table of Contents

value method. The Company includes these estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized for such transaction will not occur, or when the uncertainty associated with the variable consideration is resolved.

Chargebacks for fees and discounts represent the estimated obligations resulting from contractual commitments to sell products to Department of Veteran Affairs hospitals, participating GPO members, 340B qualified entities and other contracted customers at prices lower than the list price. The 340B Drug Discount Program is a U.S. federal government program that requires participating drug manufacturers to provide outpatient drugs to eligible health care organizations and covered entities at reduced prices. Customers claim the difference between the amount invoiced and the discounted selling price through a chargeback issued by a wholesaler. Reserves are established in the same period that the related revenue is recognized, resulting in a reduction of product revenue and trade receivables, net. Chargeback amounts are determined at the time of sale and the Company generally issues credits for such amounts within weeks of receiving notification from a wholesaler. Reserves for chargebacks consist of anticipated credits the Company expects to issue based on expected units sold and chargebacks that customers have claimed for which credits have not yet been issued.

The calculation for some of these items requires management to make estimates based on sales data, historical return data, contracts, statutory requirements and other related information that may become known in the future. The adequacy of these provisions is reviewed on a quarterly basis.

Accounts Receivable

The majority of accounts receivable arise from product sales and represent amounts due from wholesalers, hospitals, ambulatory surgery centers, specialty distributors, specialty pharmacies and individual physicians. Payment terms generally range from zero to four months from the date of the transaction, and accordingly, there is no significant financing component.

Performance Obligations

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account in Accounting Standards Codification, or ASC, 606. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied.

At contract inception, the Company assesses the goods promised in its contracts with customers and identifies a performance obligation for each promise to transfer to the customer a good that is distinct. When identifying individual performance obligations, the Company considers all goods promised in the contract regardless of whether explicitly stated in the customer contract or implied by customary business practices. The Company’s contracts with customers require it to transfer an individual distinct product, which represents a single performance obligation. The Company’s performance obligation with respect to its product sales is satisfied at a point in time, which transfers control upon delivery of EXPAREL and ZILRETTA to its customers. The Company considers control to have transferred upon delivery because the customer has legal title to the asset, physical possession of the asset has been transferred, the customer has significant risks and rewards of ownership of the asset and the Company has a present right to payment at that time.

2028 Term Loan A Facility

On March 31, 2023, the Company entered into a credit agreement (as amended to date, the “TLA Credit Agreement”) with JPMorgan Chase Bank, N.A., as administrative agent, and certain lenders, to refinance the indebtedness outstanding under the Company’s then-existing TLB Credit Agreement (as defined and discussed below). The term loan issued under the TLA Credit Agreement (the “TLA Term Loan”) was issued at a 0.30% discount and provides for a single-advance term loan A facility in the principal amount of $150.0 million, which is secured by substantially all of the Company’s and any subsidiary guarantor’s assets. Subject to certain conditions, the Company may, at any time, on one or more occasion, add one or more new classes of term facilities and/or increase the principal amount of the loans of any existing class by requesting one or more incremental term facilities. The net proceeds of the TLA Term Loan were approximately $149.6 million after deducting an original issue discount of $0.4 million.

Pacira BioSciences, Inc. | Q2 2024 Form 10-Q | Page 16

Table of Contents

On May 8, 2024, the Company, JPMorgan Chase Bank, N.A., as administrative agent, and certain lenders entered into a first amendment (the “First TLA Amendment”) to the TLA Credit Agreement. The First TLA Amendment, among other things, (i) permits the Company’s $150.0 million share repurchase program and (ii) this offering, including the Capped Call Transactions as described below.

The total debt composition of the TLA Term Loan is as follows (in thousands):


	June 30,		December 31,
	2024		2023
Term loan A facility maturing March 2028	$	110,938	$	116,563
Deferred financing costs	(861)		(988)
Discount on debt	(326)		(373)
Total debt, net of debt discount and deferred financing costs	$	109,751	$	115,202

The TLA Term Loan matures on March 31, 2028 and the TLA Credit Agreement requires quarterly repayments of principal in the amount of $2.8 million which commenced on June 30, 2023, increasing to $3.8 million commencing March 31, 2025, with a remaining balloon payment of approximately $85.3 million due at maturity. Due to voluntary principal prepayments made, the Company is not required to make further principal payments until June 2026, although the Company retains the option to do so.

The TLA Credit Agreement requires the Company to, among other things, maintain (i) a Senior Secured Net Leverage Ratio (as defined in the TLA Credit Agreement), determined as of the last day of each fiscal quarter, of no greater than 3.00 to 1.00 and (ii) a Fixed Charge Coverage Ratio (as defined in the Credit Agreement), determined as of the last day of each fiscal quarter, of no less than 1.50 to 1.00. The TLA Credit Agreement requires the Company to maintain an unrestricted cash and cash equivalents balance of at least $300.0 million ($500.0 million less a $200.0 million prepayment in the six months ended June 30, 2024) less any additional prepayments of the 2025 Notes (as defined below) at any time from 91 days prior to the maturity date through the earlier of (i) the latest maturity date of the 2025 Notes and (ii) the date on which there is no outstanding principal amount of the 2025 Notes. The TLA Credit Agreement also contains customary affirmative and negative covenants, financial covenants, representations and warranties, events of default and other provisions. As of June 30, 2024, the Company was in compliance with all financial covenants under the TLA Credit Agreement.

The Company may elect to borrow either (i) alternate base rate borrowings or (ii) term benchmark borrowings or daily simple SOFR (as defined in the TLA Credit Agreement) borrowings. Each term loan borrowing that is an alternate base rate borrowing bears interest at a rate per annum equal to (i) the Alternate Base Rate (as defined in the TLA Credit Agreement), plus (ii) a spread based on the Company’s Senior Secured Net Leverage Ratio ranging from 2.00% to 2.75%. Each term loan borrowing that is a term benchmark borrowing or daily simple SOFR borrowing bears interest at a rate per annum equal to (i) the Adjusted Term SOFR Rate or Adjusted Daily Simple SOFR (as each is defined in the Credit Agreement), plus (ii) a spread based on the Company’s Senior Secured Net Leverage Ratio ranging from 3.00% to 3.75%. During the six months ended June 30, 2024, the Company made $5.6 million voluntary principal prepayments. During the year ended December 31, 2023, the Company made a scheduled principal payment of $2.8 million as well as $30.6 million of voluntary principal prepayments. As of June 30, 2024, borrowings under the TLA Term Loan consisted entirely of term benchmark borrowings at a rate of 8.43%.

2026 Term Loan B Facility

In December 2021, the Company entered into a term loan credit agreement (the “TLB Credit Agreement”) with JPMorgan Chase Bank, N.A., as administrative agent and the initial lender. The term loan issued under the TLB Credit Agreement (the “TLB Term Loan”) was issued at a 3.00% discount and allowed for a single-advance term loan B facility in the principal amount of $375.0 million, which was secured by substantially all of the Company’s and each subsidiary guarantor’s assets. The net proceeds of the TLB Term Loan were approximately $363.8 million after deducting an original issue discount of $11.2 million.

On March 31, 2023, the Company used the $149.6 million of net borrowings under the TLA Credit Agreement and cash on hand to repay the $296.9 million then-outstanding principal under the TLB Credit Agreement and concurrently terminated the TLB Credit Agreement, which resulted in a $16.9 million loss on early extinguishment of debt. The Company incurred a prepayment fee of 2.00% of the outstanding principal balance of the TLB Term Loan in connection with the termination.

Convertible Senior Notes Due 2029

In May 2024, the Company completed a private placement of $287.5 million in aggregate principal amount of its 2.125% convertible senior notes due 2029, or 2029 Notes, and entered into an indenture with Computershare Corporate Trust, N.A., or 2029 Indenture, with respect to the 2029 Notes. The 2029 Notes accrue interest at a fixed rate of 2.125% per year, payable semiannually in arrears on May 15th and November 15th of each year. The 2029 Notes mature on May 15, 2029.

The total debt composition of the 2029 Notes is as follows (in thousands):


	June 30,
	2024
2.125% convertible senior notes due May 2029	$	287,500
Deferred financing costs	(9,106)

Total debt, net of deferred financing costs	$	278,394

Holders may convert the 2029 Notes prior to the close of business on the business day immediately preceding November 15, 2028, only if certain circumstances are met, including, but not limited to, if during the previous calendar quarter, the last reported sales price of the Company’s common stock was greater than 130% of the conversion price then applicable for at least 20 out of the last 30 consecutive trading days of the quarter. During the quarter ended June 30, 2024, the conditions for conversion were not met.

On or after November 15, 2028, until the close of business on the second scheduled trading day immediately preceding May 15, 2029, holders may convert their 2029 Notes at any time.

Upon conversion, holders will receive the principal amount of their 2029 Notes and any excess conversion value, calculated based on the per share volume-weighted average price for each of the 50 consecutive trading days during the observation period (as more fully described in the 2029 Indenture). For the principal, the Company will settle in cash per the terms of the 2029 Notes. For any excess conversion value, holders may receive cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock, at the Company’s option. The initial conversion rate for the 2029 Notes is 25.2752 shares of common stock per $1,000 principal amount, which is equivalent to an initial conversion price of $39.56 per share of the Company’s common stock. The conversion rate will be subject to adjustment in some events but will not be adjusted for any accrued and unpaid interest. The initial conversion price of the 2029 Notes represents a premium of approximately 32.5% to the closing sale price of $29.86 per share of the Company’s common stock on the Nasdaq Global Select Market on May 9, 2024, the date that the Company priced the private offering of the 2029 Notes.

As of June 30, 2024, the 2029 Notes had a market price of $996 per $1,000 principal amount. In the event of conversion, holders would forgo all future interest payments, any unpaid accrued interest and the possibility of further stock price appreciation. Upon the receipt of conversion requests, the settlement of the 2029 Notes will be paid pursuant to the terms of the 2029 Indenture. In the event that all of the 2029 Notes are converted, the Company would be required to repay the $287.5 million in principal value in cash, whereas any conversion premium would be required to be repaid in any combination of cash and shares of its common stock (at the Company’s option).

Prior to the close of business on the business day immediately preceding November 15, 2028, the 2029 Notes are convertible only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on June 30, 2024 (and only during such calendar quarter), if the last reported sale price of the Common Stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is equal to or greater than 130% of the conversion price on each applicable trading day; (2) during the five business-day period after any five consecutive trading-day period (the “measurement period”) in which the trading price per $1,000 principal amount of the 2029 Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day; (3) upon the occurrence of specified corporate events; or (4) upon a Company redemption. On or after November 15, 2028, until the close of business on the second scheduled trading day immediately preceding May 15, 2029, holders of the 2029 Notes may convert all or a portion of their 2029 Notes, at any time. Upon conversion, the 2029 Notes will be settled by paying or delivering, as applicable, cash or a combination of cash and shares of the Company’s common stock, based on the applicable conversion rate. No sinking fund is provided for the 2029 Notes.

On or after May 17, 2027 and on or before the 50th scheduled trading day immediately before the maturity date, the Company may redeem for cash all or part of the 2029 Notes if (i) the 2029 Notes are “freely tradable” (as defined in the 2029 Indenture) and any accrued and unpaid additional interest has been paid as of the date the Company sends the related notice of the redemption and (ii) the last reported sales price of the Company’s common stock exceeds 130% of the conversion price then

Pacira BioSciences, Inc. | Q2 2024 Form 10-Q | Page 18

Table of Contents

in effect for (1) each of at least 20 trading days (whether or not consecutive) during any 30 consecutive trading days ending on, and including, the trading day immediately before the date the Company sends the related notice of the redemption; and (2) the trading day immediately before the date the Company sends such notice. The redemption price of each 2029 Note to be redeemed will be the principal amount of such 2029 Note, plus accrued and unpaid interest, if any. In addition, calling any 2029 Notes for redemption will constitute a make-whole fundamental change, in which case the conversion rate applicable to those 2029 Notes, if converted in connection with the redemption, will be increased in certain circumstances. Upon the occurrence of a “make-whole fundamental change” (as defined in the 2029 Indenture), subject to a limited exception for certain cash mergers, holders may require the Company to repurchase all or a portion of their 2029 Notes for cash at a price equal to 100% of the principal amount of the 2029 Notes to be repurchased plus any accrued and unpaid interest.

While the 2029 Notes are currently classified on the Company’s condensed consolidated balance sheet at June 30, 2024 as long-term debt, the future convertibility and resulting balance sheet classification of this liability is monitored at each quarterly reporting date and is analyzed dependent upon market prices of the Company’s common stock during the prescribed measurement periods. In the event that the holders of the 2029 Notes have the election to convert the 2029 Notes at any time during the prescribed measurement period, the 2029 Notes would then be considered a current obligation and classified as such.

On May 9, 2024, in connection with the pricing of the 2029 Notes, and on May 10, 2024, in connection with the exercise in full by the initial purchasers of the 2029 Notes (the “Initial Purchasers”) of their option to purchase additional 2029 Notes, the Company entered into privately negotiated capped call transactions (the “Capped Call Transactions”) with certain of the Initial Purchasers of the 2029 Notes and/or their respective affiliates and/or other financial institutions (the “Option Counterparties”). The Capped Call Transactions are expected to cover, subject to anti-dilution adjustments substantially similar to those applicable to the 2029 Notes, the number of shares of the Company’s common stock underlying the 2029 Notes.

The Capped Call Transactions are expected to reduce the potential dilution to the Company’s common stock upon any conversion of the 2029 Notes and/or offset any potential cash payments the Company is required to make in excess of the principal amount of converted 2029 Notes, as the case may be, upon any conversion of the 2029 Notes, with such reduction and/or offset subject to a cap. The cap price of the Capped Call Transactions will initially be approximately $53.75 per share, representing a premium of approximately 80% over the closing price of $29.86 per share of the Company’s common stock on May 9, 2024, and is subject to certain adjustments under the terms of the Capped Call Transactions. The capped call was recorded as a reduction to additional paid-in capital at its cost of $26.7 million.

The Capped Call Transactions are separate transactions entered into by the Company with the Option Counterparties, are not part of the terms of the 2029 Notes and will not affect any holder’s rights under the 2029 Notes. Holders of the 2029 Notes will not have any rights with respect to the Capped Call Transactions.

In July 2020, the Company completed a private placement of $402.5 million in aggregate principal amount of its 0.750% convertible senior notes due 2025, or 2025 Notes, and entered into an indenture with Computershare Corporate Trust, N.A. (formerly Wells Fargo Bank, N.A.), or 2025 Indenture, with respect to the 2025 Notes. The 2025 Notes accrue interest at a fixed rate of 0.750% per year, payable semiannually in arrears on February 1st and August 1st of each year. The 2025 Notes mature on August 1, 2025.

In May 2024, the Company used part of the net proceeds from the issuance of the 2029 Notes to repurchase $200.0 million aggregate principal amount of the 2025 Notes in privately negotiated transactions at a discount for $191.4 million in cash (including accrued interest). The partial repurchase of the 2025 Notes resulted in a $7.5 million gain on early extinguishment of debt.

The total debt composition of the 2025 Notes is as follows (in thousands):


	June 30,		December 31,
	2024		2023
0.750% convertible senior notes due August 2025	$	202,500	$	402,500
Deferred financing costs	(1,345)		(3,906)

Total debt, net of deferred financing costs	$	201,155	$	398,594

Holders may convert the 2025 Notes at any time prior to the close of business on the business day immediately preceding February 3, 2025, only if certain circumstances are met, including, but not limited to, if during the previous calendar quarter, the last reported sales price of the Company’s common stock was greater than 130% of the conversion price then applicable for at least 20 out of the last 30 consecutive trading days of the quarter. During the quarter ended June 30, 2024, the conditions for conversion were not met.

Table of Contents

On or after February 3, 2025, until the close of business on the second scheduled trading day immediately preceding August 1, 2025, holders may convert their 2025 Notes at any time.

Upon conversion, holders will receive the principal amount of their 2025 Notes and any excess conversion value, calculated based on the per share volume-weighted average price for each of the 40 consecutive trading days during the observation period (as more fully described in the 2025 Indenture). For both the principal and excess conversion value, holders may receive cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock, at the Company’s option. The initial conversion rate for the 2025 Notes is 13.9324 shares of common stock per $1,000 principal amount, which is equivalent to an initial conversion price of $71.78 per share of the Company’s common stock. The conversion rate will be subject to adjustment in some events but will not be adjusted for any accrued and unpaid interest. The initial conversion price of the 2025 Notes represents a premium of approximately 32.5% to the closing sale price of $54.17 per share of the Company’s common stock on the Nasdaq Global Select Market on July 7, 2020, the date that the Company priced the private offering of the 2025 Notes.

As of June 30, 2024, the 2025 Notes had a market price of $938 per $1,000 principal amount. In the event of conversion, holders would forgo all future interest payments, any unpaid accrued interest and the possibility of further stock price appreciation. Upon the receipt of conversion requests, the settlement of the 2025 Notes will be paid pursuant to the terms of the 2025 Indenture. In the event that all of the 2025 Notes are converted, the Company would be required to repay the remaining $202.5 million in principal value and any conversion premium in any combination of cash and shares of its common stock (at the Company’s option).

Since August 1, 2023 (but, in the case of a redemption of less than all of the outstanding 2025 Notes, no later than the 40th scheduled trading day immediately before the maturity date), the Company may redeem for cash all or part of the 2025 Notes if the last reported sale price (as defined in the 2025 Indenture) of the Company’s common stock has been at least 130% of the conversion price then in effect for (i) each of at least 20 trading days (whether or not consecutive) during any 30 consecutive trading days ending on, and including, the trading day immediately before the date the Company sends the related notice of redemption and (ii) the trading day immediately before the date the Company sends such notice. The redemption price will equal the sum of (i) 100% of the principal amount of the 2025 Notes being redeemed, plus (ii) accrued and unpaid interest, including additional interest, if any, to, but excluding, the redemption date. In addition, calling the 2025 Notes for redemption will constitute a “make-whole fundamental change” (as defined in the 2025 Indenture) and will, in certain circumstances, increase the conversion rate applicable to the conversion of such notes if it is converted in connection with the redemption. No sinking fund is provided for the 2025 Notes.

While the 2025 Notes are currently classified on the Company’s condensed consolidated balance sheet at June 30, 2024 as long-term debt, the future convertibility and resulting balance sheet classification of this liability is monitored at each quarterly reporting date and is analyzed dependent upon market prices of the Company’s common stock during the prescribed measurement periods. In the event that the holders of the 2025 Notes have the election to convert the 2025 Notes at any time during the prescribed measurement period, the 2025 Notes would then be considered a current obligation and classified as such.

Convertible Senior Notes Due 2024 Assumed from the Flexion Acquisition

Prior to the Flexion Acquisition, in May 2017, Flexion issued an aggregate of $201.3 million principal amount of 3.375% convertible senior notes due 2024 (the “Flexion 2024 Notes”), pursuant to the indenture, dated as of May 2, 2017 (the “Original Flexion Indenture”), between Flexion and Computershare Corporate Trust, N.A. (formerly Wells Fargo Bank, N.A.), as trustee (the “Flexion Trustee”), as supplemented by the First Supplemental Indenture, dated as of November 19, 2021, between Flexion and the Flexion Trustee (the “First Supplemental Flexion Indenture” and, together with the Original Flexion Indenture, the “Flexion Indenture”). The Flexion 2024 Notes had a maturity date of May 1, 2024, were unsecured, and accrued interest at a rate of 3.375% per annum, payable semi-annually on May 1st and November 1st of each year. Upon the Flexion Acquisition, the principal was assumed and recorded at fair value by the Company.

On January 7, 2022, following the expiration of the offer to purchase, the Company accepted the $192.6 million aggregate principal amount of Flexion 2024 Notes that were validly tendered (and not validly withdrawn). No Flexion 2024 Notes were converted in connection with the Notice. The remaining principal of $8.6 million was repaid at maturity on May 1, 2024.

NOTE 9—FINANCIAL INSTRUMENTS

Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or be paid to transfer a liability in the principal or most advantageous market in an orderly transaction. To increase consistency and comparability in fair value measurements, the FASB established a three-level hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The three levels of fair value measurements are:

•Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs.

•Level 2: Observable prices that are based on inputs not quoted on active markets, but corroborated by market data.

•Level 3: Unobservable inputs that are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs.

The carrying value of financial instruments including cash and cash equivalents, accounts receivable and accounts payable approximate their respective fair values due to the short-term nature of these items. The fair value of the Company’s convertible senior notes and its TLA Term Loan are calculated utilizing market quotations from an over-the-counter trading market for these notes (Level 2). The fair value of the Company’s acquisition-related contingent consideration is reported at fair value on a recurring basis (Level 3). The carrying amounts of equity investments and convertible notes receivable without readily determinable fair values have not been adjusted for either an impairment or upward or downward adjustments based on observable transactions.

Acquisition-Related Contingent Consideration

The Company has recognized contingent consideration related to the Flexion Acquisition in the amount of $22.4 million and $24.7 million as of June 30, 2024 and December 31, 2023, respectively. The Company’s contingent consideration obligations are recorded at their estimated fair values and are revalued each reporting period if and until the related contingencies are resolved. The Company has measured the fair value of its contingent consideration using a probability-weighted discounted cash flow approach that is based on unobservable inputs and a Monte Carlo simulation. These inputs include, as applicable, estimated probabilities and the timing of achieving specified commercial and regulatory milestones, estimated forecasts of revenue and costs and the discount rates used to calculate the present value of estimated future payments. Significant changes may increase or decrease the probabilities of achieving the related commercial and regulatory events, shorten or lengthen the time required to achieve such events, or increase or decrease estimated forecasts.

Table of Contents

In November 2021, the Company completed the Flexion Acquisition, which provided for contingent consideration related to contingent value rights that were issued to Flexion shareholders and certain equity award holders which could aggregate up to a total of $372.3 million if certain regulatory and commercial milestones are met. The aggregate amount was initially $425.5 million prior to the Company’s September 2022 decision to formally discontinue further development of Flexion’s product candidate, PCRX-301. The Company’s obligation to make milestone payments is limited to those milestones achieved through December 31, 2030, and are to be paid within 60 days of the end of the fiscal quarter of achievement. During the three months ended June 30, 2024, the Company recognized a contingent consideration charge of $1.5 million primarily due to revisions to the latest discount rates. During the six months ended June 30, 2024, the Company recognized a contingent consideration gain of $2.3 million primarily due to an adjustment reflecting the probability of achieving the remaining Flexion regulatory milestone by the milestone expiration date. During the three and six months ended June 30, 2023, the Company recognized gains of $18.3 million and $6.6 million, respectively, due to adjustments to long-term forecasts which reduced the probability of meeting the sales-based contingent consideration milestones by December 31, 2030, the expiration date for achieving the milestones. The gains recognized during the six months ended June 30, 2023 were partially offset by a decrease in the assumed discount rate that is utilized in calculating the liability’s present value, based on a significant improvement in the Company’s incremental borrowing rate resulting from the TLA Credit Agreement entered into in March 2023. These adjustments were recorded within contingent consideration charges (gains), restructuring charges and other in the condensed consolidated statements of operations. At June 30, 2024, the weighted average discount rate was 8.5%.

The following table includes the key assumptions used in the valuation of the Company’s contingent consideration:


Assumption						Ranges Utilized as of June 30, 2024
Discount rates						7.8% to 9.1%
Probability of payment for remaining regulatory milestone						0%

The change in the Company’s contingent consideration recorded at fair value using Level 3 measurements is as follows (in thousands):

Available-for-Sale Investments

Short-term investments consist of asset-backed securities collateralized by credit card receivables, investment grade commercial paper and corporate, federal agency and government bonds with maturities greater than three months, but less than one year. Noncurrent investments consist of asset-backed securities collateralized by credit card receivables and contain maturities greater than one year but less than three years. Net unrealized gains and losses (excluding credit losses, if any) from the Company’s short-term investments are reported in other comprehensive income. At June 30, 2024 and December 31, 2023, all of the Company’s short-term and noncurrent investments are classified as available-for-sale investments and are determined to be Level 2 instruments, with the exception of U.S. government bonds, which are measured at fair value using standard industry models with observable inputs. The fair value of the commercial paper is measured based on a standard industry model that uses the three-month U.S. Treasury bill rate as an observable input. The fair value of the asset-backed securities and corporate bonds is principally measured or corroborated by trade data for identical issues in which related trading activity is not sufficiently frequent to be considered a Level 1 input or that of comparable securities. The fair value of U.S. government bonds is based on level 1 trading activity. At the time of purchase, all available-for-sale investments had an “A” or better rating by Standard & Poor’s.

At June 30, 2024, there were no investments available for sale that were materially less than their amortized cost.

The Company elects to recognize its interest receivable separate from its available-for-sale investments. At June 30, 2024 and December 31, 2023, the interest receivable from its available-for-sale investments recognized in prepaid expenses and other current assets was $0.2 million and $0.4 million, respectively.

Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, short-term and long-term available-for-sale investments and accounts receivable. The Company maintains its cash and cash equivalents with high-credit quality financial institutions. Such amounts may exceed federally-insured limits.

As of June 30, 2024, three wholesalers each accounted for over 10% of the Company’s accounts receivable, at 36%, 18% and 15%. At December 31, 2023, three wholesalers each accounted for over 10% of the Company’s accounts receivable, at 37%, 19% and 16%. For additional information regarding the Company’s wholesalers, see Note 2, Summary of Significant Accounting Policies. EXPAREL and ZILRETTA revenues are primarily derived from major wholesalers and specialty distributors that generally have significant cash resources. The Company performs ongoing credit evaluations of its customers as warranted and generally does not require collateral. Allowances for credit losses on the Company’s accounts receivable are maintained based on historical payment patterns, current and estimated future economic conditions, aging of accounts receivable and its write-off history. As of June 30, 2024, there were $0.2 million of allowances for credit losses on its accounts receivable associated with iovera°. As of December 31, 2023, the Company did not deem any allowances for credit losses on its accounts receivable necessary.

Share Repurchase Program

On May 7, 2024, the Company announced that its Board of Directors has approved a new share repurchase program, effective immediately, which authorizes the Company to repurchase up to an aggregate of $150.0 million of its outstanding common stock. Repurchases under this program may be made at management’s discretion on the open market or through privately negotiated transactions. The share repurchase program may be suspended or discontinued at any time by the Company and has an expiration date of December 31, 2026.

On May 9, 2024, concurrently with the pricing of the offering of the 2029 Notes, the Company entered into separate privately negotiated agreements with certain of the initial purchasers of the 2029 Notes or their respective affiliates and/or certain other financial institutions to repurchase 837,240 shares of the Company’s common stock for a total cost of $25.1 million, inclusive of $0.1 million of accrued excise tax. The repurchase occurred on May 10, 2024.

Repurchases of the Company’s common stock are accounted for at cost and recorded as treasury stock. The excise tax on repurchases of the Company’s common stock is recorded as a cost of acquiring treasury stock. Reissued treasury stock will be accounted for at average cost. Gains or losses on reissued treasury stock arising from the difference between the average cost and the fair value of the award will be recorded in additional paid-in capital.

The weighted average fair value of stock options granted during the six months ended June 30, 2024 was $13.42 per share. The fair values of stock options granted were estimated using the Black-Scholes option valuation model with the following weighted average assumptions:


Black-Scholes Weighted Average Assumption						Six Months Ended June 30, 2024
Expected dividend yield						None
Risk-free interest rate						4.00%
Expected volatility						40.80%
Expected term of options						5.25 years

Employee Stock Purchase Plan

The Company’s Amended and Restated 2014 Employee Stock Purchase Plan, or ESPP, features two six-month offering periods per year, running from January 1 to June 30 and July 1 to December 31. Under the ESPP, employees may elect to contribute after-tax earnings to purchase shares at 85% of the closing fair market value of the Company’s common stock on either the offering date or the purchase date, whichever is lesser. During the six months ended June 30, 2024, 56,077 shares were purchased and issued through the ESPP.

NOTE 12—NET INCOME PER SHARE

Basic net income per common share is calculated by dividing the net income attributable to common shares by the weighted average number of common shares outstanding during the period. Diluted net income per common share is calculated by dividing the net income attributable to common shares by the weighted average number of common shares outstanding plus dilutive potential common shares outstanding during the period.

Potential common shares include the shares of common stock issuable upon the exercise of outstanding stock options, the vesting of RSUs and the purchase of shares from the ESPP (using the treasury stock method), if applicable. Potential common shares associated with convertible senior notes are treated under the if-converted method. Adjustments are made to the diluted net income per common share calculation as if the Company had converted the convertible senior notes on the first day of each period presented. Adjustments to the numerator are made to add back the interest expense associated with the convertible senior notes on a post-tax basis. Adjustments to the denominator reflect the number of shares assumed to be convertible at the beginning of the period.

Potential common shares are excluded from the diluted net income per common share computation to the extent they would be antidilutive.

(1) During the three and six months ended June 30, 2024, there was $0.5 million and $2.7 million, respectively, of employee termination benefits related to share-based compensation excluded from the table above as they are non-cash and recorded against additional paid-in capital.

In June 2023, the Company implemented a restructuring plan in an effort to improve its operational efficiencies. The restructuring charges are predominantly related to one-time employee termination benefits through a reduction of headcount, such as severance and related costs. During the three and six months ended June 30, 2023, the Company recognized $0.9 million of restructuring charges.

Acquisition-Related Expenses

The Company recognized acquisition-related expenses of $0.2 million and $0.4 million during the three and six months ended June 30, 2024, respectively. The Company recognized acquisition-related expenses of $0.7 million and $1.2 million during the three and six months ended June 30, 2023, respectively. These costs primarily related to vacant and underutilized Flexion leases that were assumed from the Flexion Acquisition.

NOTE 15—COMMITMENTS AND CONTINGENCIES

From time to time, the Company has been and may again become involved in legal proceedings arising in the ordinary course of its business, including those related to its patents and intellectual property, product liability and government investigations. Except as described below, the Company is not presently a party to any legal proceedings that it believes to be material, and is not aware of any pending or threatened litigation against the Company which it believes could have a material adverse effect on its business, operating results, financial condition or cash flows.

MyoScience Milestone Litigation

In August 2020, the Company and its subsidiary, Pacira CryoTech, Inc. (“Pacira CryoTech”), filed a lawsuit in the Court of Chancery of the State of Delaware against Fortis Advisors LLC (“Fortis”), solely in its capacity as representative for the former securityholders of MyoScience, and certain other defendants, seeking declaratory judgment with respect to certain terms of the merger agreement for the MyoScience Acquisition (the “MyoScience Merger Agreement”), specifically related to the achievement of certain milestone payments under the MyoScience Merger Agreement. In addition, the Company and Pacira CryoTech sought general, special and compensatory damages against the other defendants related to breach of fiduciary duties in connection with the purported achievement of milestone payments under the MyoScience Merger Agreement, and breach of the MyoScience Merger Agreement and certain other agreements with the defendants. In October 2020, Fortis filed an answer and counterclaim against the Company and Pacira CryoTech seeking to recover certain milestone payments under the MyoScience Merger Agreement. The total remaining value of these milestones is $30.0 million, plus attorneys’ fees.

A trial was conducted in September 2023, and a decision is expected in the coming weeks. The Company is unable to predict the outcome of this action at this time.

eVenus Pharmaceutical Laboratories Litigations

In October 2021, the Company received a Notice Letter advising that eVenus Pharmaceutical Laboratories, Inc., or eVenus, of Princeton, New Jersey, submitted to the United States Food and Drug Administration, or FDA, an Abbreviated New Drug Application, or ANDA with a Paragraph IV certification seeking authorization for the manufacturing and marketing of a generic version of EXPAREL (266 mg/20 mL) in the U.S. prior to the expiration of U.S. Patent No. 11,033,495 (the ‘495 patent).

In November 2021, the Company filed a patent infringement suit against eVenus and its parent company in the U.S. District Court for the District of New Jersey (21-cv-19829) asserting infringement of the ‘495 patent. This triggered an

Pacira BioSciences, Inc. | Q2 2024 Form 10-Q | Page 30

Table of Contents

automatic 30-month stay of final approval of the eVenus ANDA which expired on July 1, 2024. On January 6, 2022, eVenus filed an Answer with counterclaims to the Complaint, alleging the ‘495 patent is invalid and/or not infringed through the manufacture, sale, or offer for sale of the product described in eVenus’s ANDA submission.

In December 2021, the Company received a second Notice Letter advising that eVenus submitted to the FDA an amendment to its ANDA with a Paragraph IV Certification seeking authorization for the manufacturing and marketing of a generic version of EXPAREL (133 mg/10 mL) in the U.S. prior to the expiration of the ‘495 patent. In the second Notice Letter, eVenus also advised that it submitted a Paragraph IV Certification to the FDA seeking authorization for the manufacturing and marketing of a generic version of EXPAREL (266 mg/20 mL and 133 mg/10 mL) in the U.S. prior to the expiration of U.S. Patent No. 11,179,336 (the ‘336 patent). eVenus further alleges in the Notice Letter that both the ‘495 patent and the ‘336 patent are invalid and/or not infringed.

In February 2022, the Company filed a second patent infringement suit against eVenus and its parent company in the U.S. District Court for the District of New Jersey (22-cv-00718) asserting that the 133 mg/10 mL ANDA product will infringe the ‘495 and ‘336 patents and that the 266 mg/20 mL ANDA product will infringe the ‘336 patent. This filing triggered a second automatic 30-month stay of final approval for the 133 mg/10 mL ANDA product which expired on July 1, 2024. The first and second patent infringement suits were consolidated.

In February 2023, eVenus filed its first amended answer to the first amended complaint, alleging patent invalidity, non-infringement and inequitable conduct. The Company has denied the allegations in eVenus’s first amended answer. The Company has subsequently voluntarily dismissed its claims with respect to the ‘336 Patent. The trial on the remaining claim was conducted in February 2024 with a decision expected in the coming days.

In April 2023, the Company filed a third patent infringement suit against eVenus, its parent company, and Fresenius Kabi USA, LLC, or Fresenius, in the U.S. District Court for the District of New Jersey (23-cv-2367) asserting that the 133 mg/10 mL and 266 mg/20 mL ANDA products will infringe U.S. Patent No. 11,426,348 (the ‘348 patent). In July 2023, eVenus filed its answer with claims for declaratory judgment, alleging patent invalidity, non-infringement and inequitable conduct with respect to the ‘348 patent as well as the Company’s other patents, U.S. Patent Nos. 11,278,494; 11,304,904; 11,311,486; 11,357,727 and 11,452,691. The parties have subsequently dismissed all patents other than the ‘348 patent from this litigation. This action is in the discovery stage.

In May 2024, the Company filed a fourth patent infringement suit against eVenus, its parent company and Fresenius in the U.S. District Court for the District of New Jersey (24-cv-6294) asserting that the 133 mg/10 mL and 266 mg/20 mL ANDA products will infringe U.S. Patent Nos. 11,819,574 and 11,819,575. This action is in the pleadings stage.

In July 2024, the Company filed a fifth patent infringement suit against eVenus, its parent company and Fresenius in the U.S. District Court for the District of New Jersey (24-cv-7680) asserting that the 133 mg/10 mL and 266 mg/20 mL ANDA products will infringe U.S. Patent No. 11,925,706. This action is in the pleadings stage.

The Company is unable to predict the outcome of these litigations at this time.

Research Development Foundation

Pursuant to an agreement with the Research Development Foundation, or RDF, the Company was required to pay RDF a low single-digit royalty on the collection of revenues from certain products, for as long as certain patents assigned to the Company under the agreement remain valid. RDF has the right to terminate the agreement for an uncured material breach by the Company, in connection with its bankruptcy or insolvency or if it directly or indirectly opposes or disputes the validity of the assigned patent rights. The Company’s ‘495 patent was issued on June 15, 2021. Thereafter, RDF asserted that the issuance of that patent extends the Company’s royalty obligations under the agreement until 2041. The Company believes that the royalty period under the agreement ended on December 24, 2021 with the expiration of its U.S. Patent No. 9,585,838. Because of the disagreement over the interpretation of the agreement, in December 2021, the Company filed a declaratory judgment lawsuit in the U.S. District Court for the District of Nevada (21-cv-02241). The lawsuit seeks a declaration from the court that the Company owes no royalties to RDF with respect to its EXPAREL product after December 24, 2021.

On August 8, 2023, the U.S. District Court, District of Nevada, granted the Company’s motion for partial summary judgment in respect to the Company’s claim for a declaration that it no longer owes royalties for EXPAREL made under the 45-liter manufacturing process as of December 24, 2021. As a result, the Company expects to receive $14.5 million from RDF, representing the royalties that the Company paid to RDF under protest after December 24, 2021 for EXPAREL made from the 45-liter manufacturing process. Once it becomes probable that the settlement amount will be received, the Company will record a settlement gain within other operating income (expense), net in the condensed consolidated statement of operations. In November 2023, the U.S. District Court, District of Nevada conducted a mediation that did not result in a settlement. During

Pacira BioSciences, Inc. | Q2 2024 Form 10-Q | Page 31

the pendency of the remaining lawsuit, the Company will continue to pay royalties associated with the 200-liter EXPAREL manufacturing process to RDF under protest. A trial is currently scheduled for September 2024. The Company is unable to predict the outcome of this action at this time.

Other Commitments and Contingencies

Pediatric Trial Commitments

The FDA, as a condition of EXPAREL approval, has required the Company to study EXPAREL for infiltration and as a brachial plexus block in pediatric patients. The Company was granted deferrals for the required pediatric trials until after the indications were approved in adults. Similarly, in Europe, the Company agreed with the European Medicines Agency, or EMA, on a Pediatric Investigation Plan as a prerequisite for submitting a Marketing Authorization Application (MAA) in the E.U. Despite the U.K.’s withdrawal from the E.U., the agreed pediatric plan is applicable in the U.K.

The Company received notification from the FDA in October 2023 that its pediatric studies requirement had been waived for the indication of brachial plexus interscalene nerve block to produce postsurgical regional analgesia in pediatric patients. The Company is still working with the FDA, EMA and Medicines and Healthcare Regulatory Agency (MHRA) to finalize the regulatory pathways for its remaining pediatric commitments.

Contingent Milestone Payments

Refer to Note 9, Financial Instruments, for information on potential contingent milestone payments related to the Flexion Acquisition.

PCRX-201

PCRX-201, a novel, intra-articular gene therapy product candidate that produces the anti-inflammatory protein interleukin-1 receptor antagonist (IL-1Ra) treating OA pain in the knee, was added to the Company’s portfolio as part of the Flexion Acquisition in November 2021. Prior to the Flexion Acquisition, in February 2017, Flexion entered into an agreement with GQ Bio Therapeutics GmbH to acquire the global rights to PCRX-201, a gene therapy product candidate. As part of the agreement, up to an aggregate of $56.0 million of payments could become due upon the achievement of certain development and regulatory milestones, including up to $4.5 million through initiation of a Phase 2 proof of concept clinical trial and, following successful proof of concept, up to an additional $51.5 million in development and global regulatory approval milestone payments.

In February 2024, the FDA granted a Regenerative Medicine Advanced Therapy (RMAT) designation to PCRX-201 for the treatment of OA pain of the knee.

NOTE 16—SUBSEQUENT EVENT

In July 2024, eVenus received FDA approval of a generic version of EXPAREL—the Company’s bupivacaine liposome injectable suspension product. This generic version of EXPAREL is part of multiple ongoing and pending patent infringement litigations, with a decision on the first case expected in the coming days.

Overview

Pacira is the therapeutic area leader in non-opioid pain management with a stated corporate mission of providing non-opioid pain management options to as many patients as possible and redefining the role of opioids for rescue therapy only. Our long-acting, local analgesic EXPAREL® (bupivacaine liposome injectable suspension) utilizes our unique pMVL drug delivery technology that encapsulates drugs without altering their molecular structure and releases them over a desired period of time. In the U.S., EXPAREL is a long-acting, non-opioid option proven to manage postsurgical pain. EXPAREL is the only product indicated for local analgesia via infiltration in patients aged six years and older and regional analgesia via interscalene brachial plexus nerve block, sciatic nerve block in the popliteal fossa and adductor canal block in adults. In Europe, EXPAREL is approved as a brachial plexus block or femoral nerve block for treatment of post-operative pain in adults, and as a field block for treatment of somatic post-operative pain from small- to medium-sized surgical wounds in adults and children aged six years and older. Since its initial approval in 2011, more than 14 million patients have been treated with EXPAREL. We drop-ship EXPAREL directly to end-users based on orders placed to wholesalers or directly to us, and there is no product held by wholesalers. With the acquisition of Flexion Therapeutics, Inc., or Flexion, in November 2021 (the “Flexion Acquisition”), we acquired ZILRETTA® (triamcinolone acetonide extended-release injectable suspension), the first and only extended-release, intra-articular, or IA, therapy that can provide major relief for osteoarthritis, or OA, knee pain for three months and has the potential to become an alternative to hyaluronic acid, platelet rich plasma injections or other early intervention treatments. With the acquisition of MyoScience, Inc., or MyoScience, in April 2019 (the “MyoScience Acquisition”), we acquired iovera°®, a handheld cryoanalgesia device used to deliver a precise, controlled application of cold temperature to targeted nerves, which we sell directly to end users. EXPAREL, ZILRETTA and iovera° are highly complementary products as long-acting, non-opioid therapies that alleviate pain.

We expect to continue to pursue the expanded use of EXPAREL, ZILRETTA and iovera° in additional procedures; progress our earlier-stage product candidate pipeline; advance regulatory activities for EXPAREL, ZILRETTA, iovera°, PCRX-201 and our other product candidates; invest in sales and marketing resources for EXPAREL, ZILRETTA and iovera°; expand and enhance our manufacturing capacity for EXPAREL, ZILRETTA and iovera°; invest in products, businesses and technologies; and support legal matters.

Global Economic Conditions

Direct and indirect effects of global economic conditions have in the past, and may continue to, negatively impact our business, financial condition and results of operations. Such impacts may include the effect of prolonged periods of inflation which could, among other things, result in higher costs for labor, raw materials and services; cause patients to defer or cancel medical procedures, thereby adversely impacting our revenues; and negatively impact our suppliers which could result in longer lead-times or the inability to secure a sufficient supply of materials. The current macroeconomic environment remains dynamic and subject to rapid and possibly material changes. Additional negative impacts may also arise that we are unable to foresee. The nature and extent of such impacts will depend on future developments, which are highly uncertain and cannot be predicted.

Recent Highlights

•In May 2024, we completed a private placement of $287.5 million in aggregate principal amount of 2.125% convertible senior notes due 2029, or 2029 Notes. We used part of the net proceeds from the issuance of the 2029 Notes to repurchase $200.0 million in aggregate principal amount of our 0.750% convertible senior notes due 2025, or 2025 Notes, in privately-negotiated transactions at a discount for $191.4 million in cash (including accrued interest). The partial repurchase of the 2025 Notes resulted in a $1.5 million proportional reduction of deferred financing costs and a $7.5 million gain on early extinguishment of debt. For more information, see Note 8, Debt, to our condensed consolidated financial statements included herein and “Liquidity and Capital Resources” below.

•In May 2024, we announced a new share repurchase program which authorizes us to repurchase up to an aggregate of $150 million of our outstanding common stock. Repurchases under the program may be made at management’s discretion on the open market or through privately negotiated transactions. The share repurchase program may be suspended or discontinued at any time by us and has an expiration date of December 31, 2026. Concurrently with the pricing of the offering of the 2029 Notes, we entered into separate privately negotiated agreements with certain of the initial purchasers of the 2029 Notes or their respective affiliates and/or certain other financial institutions to repurchase 837,240 shares of our common stock for $25.0 million.

•In July 2024, the Centers for Medicare and Medicaid Services, or CMS, issued its proposed Hospital Outpatient Prospective Payment System and Ambulatory Surgical Center Payment System rule for 2025. In the proposed rule, EXPAREL is one of six covered non-opioids—two of which are specific to ophthalmology— qualifying for separate Medicare reimbursement in both the ambulatory surgical center, or ASC, and hospital outpatient, or HOPD, settings, where EXPAREL will be reimbursed at 106% of the average sales price (also called “ASP + 6% reimbursement”). Pending finalization, this policy would go into effect beginning January 1, 2025. The proposed rule reflects impending implementation of the NOPAIN Act, which mandates separate CMS payment for qualifying non-opioid drugs and devices across HOPD and ASC settings. The law was passed as part of the Consolidated Appropriations Act of 2023.

EXPAREL

In the U.S., EXPAREL is currently indicated for local analgesia via infiltration in patients aged six years and older and regional analgesia via interscalene brachial plexus nerve block, sciatic nerve block in the popliteal fossa, and adductor canal block in adults. Safety and efficacy have not been established in other nerve blocks. In Europe, EXPAREL is approved as a brachial plexus block or femoral nerve block for treatment of post-operative pain in adults, and as a field block for treatment of somatic post-operative pain from small- to medium-sized surgical wounds in adults and children aged six years and older.

EXPAREL Label Expansion

•Expanding utilization in lower extremity nerve block indications. In February 2024, we launched EXPAREL in two key lower extremity nerve blocks—namely an adductor canal block and a sciatic nerve block in the popliteal fossa. We believe these two key nerve blocks will expand EXPAREL utilization within surgeries of the knee, lower leg, and foot and ankle procedures. The launch is supported by two successful head-to-head Phase 3 studies in which EXPAREL demonstrated four days of superiority to bupivacaine.

•Pediatrics. We have launched a Phase 1 pharmacokinetic study of EXPAREL as a single-dose post-surgical infiltration administration in patients under six years of age. If successful, we expect this study, followed by a Phase 3 registration study, will support expansion of the EXPAREL labels in the U.S., European Union, or E.U., and United Kingdom, or U.K. We are also discussing with the FDA, EMA and Medicines and Healthcare Products Regulatory Agency (MHRA) our regulatory strategy for EXPAREL administered as a nerve block in the pediatric setting. We received notification from the FDA in October 2023 that our pediatric studies requirement had been waived for the indication of brachial plexus interscalene nerve block to produce postsurgical regional analgesia in pediatric patients.

•Stellate ganglion block. Planning is underway for a multicenter EXPAREL Phase 3 registration program as a stellate ganglion block for preventing postoperative atrial fibrillation after cardiothoracic surgery. We worked with a steering committee of Key Opinion Leaders, or KOLs, in regional anesthesia and stellate ganglion blocks to design our program and we are awaiting FDA feedback on study design. We believe a stellate ganglion block utilizing EXPAREL will be critical in an unmet need with post-operative atrial fibrillation, or POAF. POAF is a common and costly complication after cardiothoracic surgery, occurring after up to 40% of cardiac procedures and 20% of thoracic procedures, and often results in an extended intensive care unit and/or hospital stay, as well as higher long-term risk. A stellate ganglion block is a sympathetic nerve block which can stabilize the heart. Since POAF typically occurs around the third day after surgery, a long-acting block with EXPAREL provided at the time of surgery may enhance current prophylactic measures.

Additionally, we initiated a second Phase 1 study of EXPAREL for intrathecal analgesia in June 2023.

EXPAREL Clinical Benefits

We believe EXPAREL can replace the use of bupivacaine delivered via elastomeric pumps as the foundation of a multimodal regimen for long-acting postsurgical pain management. Based on our clinical data, EXPAREL:

•provides long-lasting local or regional analgesia;

•is a ready-to-use formulation;

•expands easily with saline or lactated Ringer’s solution to reach a desired volume;

•can be administered for local analgesia via infiltration and for regional analgesia via field block, as well as brachial plexus nerve block, sciatic nerve block in the popliteal fossa and adductor canal block; and

•facilitates treatment of a variety of surgical sites.

We believe EXPAREL is a key component of long-acting postsurgical pain management regimens that reduce the need for opioids. Based on the clinical data from our Phase 3 and Phase 4 clinical studies as well as data from retrospective health outcomes studies, EXPAREL significantly reduces opioid usage while improving postsurgical pain management.

ZILRETTA

ZILRETTA is the first and only extended-release, intra-articular therapy for OA knee pain. ZILRETTA employs a proprietary microsphere technology combining triamcinolone acetonide, or TA, a commonly administered, immediate-release corticosteroid, with a poly lactic-co-glycolic acid, or PLGA, matrix to provide extended pain relief. PLGA is a proven extended-release delivery vehicle that is metabolized to carbon dioxide and water as it releases drug in the intra-articular space and is used in other approved drug products and surgical devices. The ZILRETTA microspheres slowly and continuously release triamcinolone acetonide into the knee to provide significant pain relief for 12 weeks, with some people experiencing pain relief through 16 weeks. ZILRETTA was approved by the FDA in October 2017 and launched in the U.S. shortly thereafter.

We believe ZILRETTA’s extended-release profile may also provide effective treatment for OA pain of the shoulder and we recently launched a Phase 3 registration study to evaluate the safety and efficacy of ZILRETTA for the management of OA pain of the shoulder. If the study is successful, we plan to seek approval to expand the ZILRETTA label to include OA pain of the shoulder.

ZILRETTA Clinical Benefits

ZILRETTA combines TA, a commonly administered steroid, with a proprietary, extended-release microsphere technology to administer extended therapeutic concentrations in the joint and persistent analgesic effect.

Based on the strength of its pivotal and other clinical trials, we believe that ZILRETTA represents an important treatment option for the millions of patients in the U.S. in need of safe and effective extended relief from OA knee pain. The pivotal Phase 3 trial showed that ZILRETTA significantly reduced OA knee pain for 12 weeks, with some people experiencing pain relief through 16 weeks. We believe that ZILRETTA has the potential to become the corticosteroid of choice given its safety and efficacy profile, and the fact that it is the first and only extended-release corticosteroid on the market. In September 2021, the American Association of Orthopaedic Surgeons, or AAOS, updated its evidence-based clinical practice guidelines, finding ZILRETTA can improve patient outcomes over traditional immediate-release corticosteroids.

iovera°

The iovera° system is a non-opioid handheld cryoanalgesia device used to deliver precise, controlled doses of cold temperature to targeted nerves. It is FDA 510(k) cleared in the U.S., has a CE mark in the E.U. and is cleared for marketing in Canada for the blocking of pain. We believe the iovera° system is highly complementary to EXPAREL and ZILRETTA as a non-opioid therapy that alleviates pain using a non-pharmacological nerve block to disrupt pain signals being transmitted to the brain from the site of injury or surgery. It is also indicated for the relief of pain and symptoms associated with arthritis of the knee for up to 90 days.

iovera° Clinical Benefits

There is a growing body of clinical data demonstrating success with iovera° treatment for a wide range of chronic pain conditions. Some of our strongest data relates directly to the improvement of OA pain of the knee. In a pivotal trial evaluating iovera° for knee OA pain, the majority of the patients suffering from OA pain of the knee experienced pain relief up to 150 days after being treated with iovera°.

Surgical intervention is typically a last resort for patients suffering from knee OA pain. Treatment with iovera° has also demonstrated effectiveness for managing pain associated with knee replacements. Specifically, findings demonstrated reductions in opioids, including:

•The daily morphine equivalent consumption in the per protocol group analysis was significantly lower at 72 hours (p<0.05), 6 weeks (p<0.05) and 12 weeks (p<0.05).

•Patients who were administered iovera° were far less likely to take opioids six weeks after surgery. The number of patients taking opioids six weeks after total knee arthroplasty, or TKA, in the control group was three times the number of patients taking opioids in the cryoanalgesia group (14 percent vs. 44 percent, p<0.01).

Pacira BioSciences, Inc. | Q2 2024 Form 10-Q | Page 36

Table of Contents

•Patients in the iovera° group demonstrated a statistically significant reduction in pain scores from their baseline pain scores at 72 hours (p<0.05) and at 12 weeks (p<0.05).

We believe these data validate iovera° as a clinically meaningful non-opioid alternative for patients with knee OA as well as those undergoing TKA, and that iovera° offers the opportunity to provide patients with non-opioid pain control well in advance of any necessary surgical intervention through a number of key product attributes:

•iovera° is safe and effective with immediate pain relief that can last for months as the nerve regenerates over time;

•iovera° is repeatable, with no diminishing effectiveness over time and repeat use;

•The iovera° technology does not risk damage to the surrounding tissue;

•iovera° is a convenient handheld device with a single-use procedure-specific Smart Tip; and

•iovera° can be delivered precisely using imaging guidance or an anatomical landmark.

A study published in 2021 that included 267 patients undergoing TKA (169 who underwent cryoneurolysis with iovera° compared to 98 patients who did not receive iovera° treatment) showed that patients who were treated with iovera° had 51% lower daily morphine milligram equivalents during their hospital stay and a 22% lower mean pain score versus those who were not. In addition, the iovera° group had greater function at discharge, a shorter length of hospital stay and received significantly fewer opioids, including discharge prescriptions at week 2 and week 6 after surgery.

In September 2021, the AAOS updated its evidence-based clinical practice guidelines, reporting that denervation therapy—including cryoneurolysis—may reduce knee pain and improve function in patients with symptomatic OA of the knee.

We are currently sponsoring a prospective, real-world registry called the Innovations in Genicular Outcomes Registry, or iGOR, which is a patient focused registry governed in collaboration with a steering committee of scientific experts that evaluates clinical, economic- and health-related patient-reported outcomes in patients who have received any treatment for knee OA pain, including TKA, for a minimum of 18 months. A unique feature of iGOR is that if patients receive additional treatments for OA, data capture resets so outcomes of their treatment journey can be followed over multiple years. Unlike in clinical studies, treatment decisions in iGOR are decided by physicians and patients in a shared decision-making manner rather than being driven by treatment assignment, so that outcomes are truly those from real-world applications. The iGOR registry is tracking outcomes of iovera°, ZILRETTA and EXPAREL, as well as comparator treatments. Early outcomes from iGOR have shown that patients who receive iovera° prior to TKA have less pain, improved function and improved sleep for six months after surgery versus patients who do not receive iovera°.

In addition, a pilot randomized control trial evaluating iovera° for the treatment of lower back pain showed that it had significantly greater improvements in pain and disability, and required fewer injections over a year, compared to patients who were treated with radiofrequency ablation. This data supports the development of a longer Smart Tip that is currently underway which would allow for broader use of iovera° for the treatment of lower back pain.

Beyond treatment for pain, observational data has been presented at multiple congresses showing effectiveness of iovera° for the treatment of upper limb spasticity over 90 days by targeting motor nerves. We currently have a pivotal trial underway to demonstrate the efficacy and safety of iovera° for treating spasticity.

The Osteoarthritis Market

OA is the most common form of arthritis. It is also called degenerative joint disease and occurs most frequently in the hands, hips and knees. With OA, the cartilage within a joint begins to break down and the underlying bone begins to change. These changes usually develop slowly and worsen over time. OA can cause pain, stiffness and swelling. In some cases, it also causes reduced function and disability—some people are no longer able to do daily tasks or work. According to the Centers for Disease Control and Prevention (CDC), OA affects over 32.5 million adults in the U.S.

The lifetime risk of developing symptomatic knee OA is 45 percent according to the Arthritis Foundation. The prevalence of symptomatic knee OA increases with each decade of life, with the annual incidence of knee OA being highest between age 55 and 64 years old. There are 14 million individuals in the U.S. who have symptomatic knee OA, and nearly two million are under the age of 45. Surgical intervention is typically a last resort for patients suffering from OA of the knee.

With ZILRETTA, we now offer clinicians the flexibility to individualize OA knee pain treatment with either ZILRETTA or a drug-free nerve block with iovera° based on patient factors and preference, physician training, site of care and reimbursement considerations.

Clinical Development Programs

PCRX-201

PCRX-201 is a novel, helper-dependent adenoviral vector expressing interleukin-1 receptor antagonist (IL-1Ra). After injection, the vector enters joint cells and turns them into factories to produce sustained therapeutic levels of IL-1Ra and inhibit the IL-1 pathway to manage pain and mitigate OA-related joint damage while remaining localized to the joint space. In a Phase 1 proof-of-concept study of patients with moderate to severe OA of the knee, PCRX-201 was well tolerated with improvements in knee pain observed across all doses. The study enrolled 72 patients in two three-dose cohorts: a co-administered IA steroid cohort and a cohort that did not receive a steroid. PCRX-201 was well tolerated, with efficacy observed through at least 52 weeks at all doses and cohorts. The highest level of efficacy was achieved in the co-administered steroid group, which showed a greater percentage of patients with at least a 50% improvement in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain and stiffness scores, as well as a meaningful improvement in (Knee Injury and Osteoarthritis Outcomes Score) KOOS functional assessment. The one-year data were presented at the Osteoarthritis Research Society International (OARSI) 2024 World Congress in April 2024. We now have two-year efficacy and safety data that we have submitted for presentation at a medical meeting later this year. Given the highly encouraging Phase 1 data, we are preparing to launch a second clinical study in knee OA.

In February 2024, the FDA granted PCRX-201 a Regenerative Medicine Advanced Therapy, or RMAT, designation. Established under the 21st Century Cures Act, RMAT designation is a dedicated program designed to expedite the development and review processes for promising therapies, including genetic therapies, that are intended to treat, modify, reverse or cure a serious or life-threatening disease or condition, and for which preliminary clinical evidence indicates that the drug or therapy has the potential to address an unmet medical need. PCRX-201 is the first gene therapy product candidate to receive RMAT designation for OA.

External Innovation

In parallel to our internal clinical programs, we are pursuing innovative acquisition targets that are complementary to EXPAREL, ZILRETTA and iovera° and are of great interest to the surgical and anesthesia audiences we are already calling on today. We are using a combination of strategic investments, in-licensing and acquisition transactions to buildout a pipeline of innovation to improve patients’ journeys along the neural pain pathway. The strategic investments we have made to support promising early-stage platforms are summarized below:

EXPAREL revenue increased 1% in both the three and six months ended June 30, 2024 versus 2023. Components of the increase included a 3% increase in gross vial volume in both the three and six months ended June 30, 2024 versus 2023, which was offset by a shift in vial mix. EXPAREL revenue was also impacted by a 1% increase in selling price per unit in both the three and six months ended June 30, 2024 versus 2023, related to a January 2024 price increase, net of increases in sales related allowances as a result of group purchasing organization contracting.

ZILRETTA revenue increased 5% and 6% in the three and six months ended June 30, 2024 versus 2023, primarily due to a 3% and 5% increase in net selling price per unit related to a January 2024 price increase and a 3% and 1% increase in kit volume, respectively.

Net product sales of iovera° increased 29% and 28% in the three and six months ended June 30, 2024 versus 2023, respectively, primarily due to increases of 29% and 32% in Smart Tip volume, partially offset by increased sales related allowances and accruals.

Bupivacaine liposome injectable suspension revenue increased more than 100% in both the three and six months ended June 30, 2024 versus 2023. Its related royalties also substantially increased in both the three and six months ended June 30, 2024 versus 2023 primarily due to the sales mix of vial sizes and the timing of orders placed for veterinary use.

The following tables provide a summary of activity with respect to our sales related allowances and accruals related to EXPAREL and ZILRETTA for the six months ended June 30, 2024 and 2023 (in thousands):

Total research and development expense increased 8% and 7% in the three and six months ended June 30, 2024 versus 2023, respectively.

Clinical and preclinical development expense increased 57% and 39% in the three and six months ended June 30, 2024 versus 2023, respectively, due to the start-up of and enrollment in a ZILRETTA shoulder trial, an EXPAREL intrathecal trial and an EXPAREL pediatric trial, and start-up activities in an iovera° spasticity trial. These increases were partially offset by the winding down of a PCRX-201 Phase 1 trial for knee OA as two-year follow-up visits of subjects were completed in November 2023. This Phase 1 trial remains on track for completion by November 2026, the last year of the follow-up period for the last patient dosed. In addition, toxicology studies for product candidates were completed in 2023.

Product development and manufacturing capacity expansion expense decreased 21% and 13% in the three and six months ended June 30, 2024 versus 2023, respectively, primarily attributable to the near-completion of pre-commercial scale-up activities of our EXPAREL manufacturing capacity at our Science Center Campus in San Diego, California, subsequently placed into service in July 2024. The FDA approved an sNDA for our 200-liter EXPAREL manufacturing suite in February 2024. This decrease is partially offset by ongoing product development costs related to PCRX-201 and an iovera° medial branch Smart Tip.

Regulatory and other expense increased 12% and 14% in the three and six months ended June 30, 2024 versus 2023, respectively, due to increased enrollment and additional sites related to an observational registry study which tracks patients’ symptoms and experience with pain management related to OA of the knee.

Stock-based compensation increased 12% and 4% in the three and six months ended June 30, 2024 versus 2023, respectively, primarily due to greater equity awards granted to personnel.

Selling, General and Administrative Expenses

Sales and marketing expenses primarily consist of compensation and benefits for our sales force and personnel that support our sales, marketing, medical and scientific affairs operations, expenses related to communicating the health outcome benefits of our products, investments in provider-level market access and patient reimbursement support and educational programs for our customers. General and administrative expenses consist of compensation and benefits for legal, finance, regulatory activities related to approved products and indications, compliance, information technology, human resources, business development, executive management and other supporting personnel. It also includes professional fees for legal, audit, tax and consulting services. Stock-based compensation expense relates to the costs of stock option grants, RSU awards and our ESPP.

Total selling, general and administrative expense increased 5% and 3% in the three and six months ended June 30, 2024 versus 2023, respectively.

Sales and marketing expense increased 4% in the three months ended June 30, 2024 versus 2023 and decreased 1% in the six months ended June 30, 2024 versus 2023. The three months increase was driven by investing in programs to drive awareness and education for our customers and enhance our marketing, market access and reimbursement teams and value creation for the implementation of separate Medicare reimbursement for EXPAREL at average sales price plus 6 percent in outpatient settings beginning in January 2025 as part of the NOPAIN Act. We expect investments in these programs to increase in the second half of 2024 as we launch our national campaign—Make the NOPAIN Pact—which targets hospital pharmacists, administrators, clinicians and revenue management teams and is focused on ensuring these audiences are ready for the commencement of the NOPAIN Act. These increases were partially offset by the impact of a February 2024 restructuring program. The six months decrease was attributable to the impact of the February 2024 restructuring program.

General and administrative expense increased 3% and 11% in the three and six months ended June 30, 2024 versus 2023, respectively. The three and six month increases were primarily driven by third-party management consulting to assess strategic opportunities and market assessments for our products, partially offset by lower legal fees for ongoing litigation. Incrementally, the six months increase also included compensatory costs associated with the transition to our new Chief Executive Officer effective January 2, 2024, which include compensation related to the current Chief Executive Officer and to the former Chief Executive Officer who remains employed by the Company in an advisory role.

For more information on our ongoing litigation, see Note 15, Commitments and Contingencies, to our condensed consolidated financial statements included herein.

Stock-based compensation increased 13% and 4% for the three and six months ended June 30, 2024 versus 2023, respectively, primarily due to greater equity awards granted to personnel.

Contingent Consideration Charges (Gains), Restructuring Charges and Other

The following table provides a summary of the costs related to the contingent consideration, acquisition-related charges and restructuring charges during the periods indicated, including percent changes (dollar amounts in thousands):


	Three Months Ended June 30,				% Increase / (Decrease)	Six Months Ended June 30,				% Increase / (Decrease)

	2024		2023			2024		2023
Flexion contingent consideration	$	1,509	$	(18,258)	N/A	$	(2,297)	$	(6,640)	(65)%
Restructuring charges	996		936		6%	6,531		936		100% +

Acquisition-related expenses	230		709		(68)%	404		1,198		(66)%

Total contingent consideration charges (gains), restructuring charges and other	$	2,735	$	(16,613)	N/A	$	4,638	$	(4,506)	N/A

Total contingent consideration charges (gains), restructuring charges and other for the three and six months ended June 30, 2024 included charges of $2.7 million and $4.6 million, respectively. Total contingent consideration charges (gains), restructuring charges and other for the three and six months ended June 30, 2023 included gains of $16.6 million and $4.5 million, respectively.

During the three months ended June 30, 2024, we recognized a contingent consideration charge of $1.5 million primarily due to revisions to the latest discount rates. During the six months ended June 30, 2024, we recognized a contingent consideration gain of $2.3 million primarily due to an adjustment reflecting the probability of achieving the remaining Flexion regulatory milestone by the milestone expiration date.

During the three and six months ended June 30, 2023, we recognized contingent consideration gains of $18.3 million and $6.6 million, respectively. These gains were primarily due to adjustments to long-term forecasts which reduced the probability of meeting the sales-based contingent consideration milestones for the Flexion Acquisition by the December 31, 2030 milestone expiration date. The gains recognized during the six months ended June 30, 2023 were partially offset by a decrease in the assumed discount rate that is utilized in calculating the liability’s present value, based on a significant improvement in our incremental borrowing rate.

During the three and six months ended June 30, 2024, we recognized restructuring charges of $1.0 million and $6.5 million, respectively, related to employee termination benefits, such as the acceleration of share-based compensation, severance, and, to a lesser extent, other employment-related termination costs, as well as contract termination costs. During the three and six months ended June 30, 2023, we implemented a restructuring plan in an effort to improve our operational efficiencies and recognized $0.9 million in one-time employee termination benefits through a reduction of headcount.

During the three and six months ended June 30, 2023, we recognized acquisition-related expenses of $0.7 million and $1.2 million, respectively, primarily related to severance and other employee related costs, legal and other professional fees, third-party services and other one-time charges associated with the Flexion Acquisition.

For more information, see Note 9, Financial Instruments and Note 14, Contingent Consideration Charges (Gains), Restructuring Charges and Other, to our condensed consolidated financial statements included herein.

Other Income (Expense), Net

The following table provides information regarding other income (expense), net during the periods indicated, including percent changes (dollar amounts in thousands):


	Three Months Ended June 30,				% Increase / (Decrease)	Six Months Ended June 30,				% Increase / (Decrease)

	2024		2023			2024		2023
Interest income	$	4,749	$	2,111	100% +	$	8,652	$	5,253	65%
Interest expense	(3,884)		(3,865)		—%	(7,200)		(13,454)		(46)%

Total other income (expense), net	$	8,344	$	(2,023)	N/A	$	8,772	$	(25,406)	N/A

Total other income, net was $8.3 million and $8.8 million in the three and six months ended June 30, 2024, respectively. Total other expense, net was $2.0 million and $25.4 million in the three and six months ended June 30, 2023, respectively.

The substantial increases in interest income in the three and six months ended June 30, 2024 versus 2023 were due to higher interest rates and overall investment balances.

The 46% decrease in interest expense during the six months ended June 30, 2024 versus 2023 was primarily driven by lower principal outstanding associated with the TLA Term Loan (as defined below) that was entered into on March 31, 2023 which replaced our then-outstanding TLB Term Loan (as defined below) that had a higher principal balance and interest rate.

In the three and six months ended June 30, 2024, we recognized a $7.5 million gain on early extinguishment of debt in conjunction with the repurchase of $200.0 million principal of our 2025 Notes. The partial repurchase of the 2025 Notes was completed with our net proceeds from the issuance of the 2029 Notes.

In the six months ended June 30, 2023, in conjunction with the entry into the TLA Credit Agreement, we incurred a $16.9 million loss on early extinguishment of debt as a result of the retirement of $287.5 million aggregate principal of our TLB Term Loan (as defined below).

For more information, see Note 8, Debt, to our condensed consolidated financial statements included herein.

Income Tax Expense

The following table provides information regarding our income tax expense during the periods indicated, including percent changes (dollar amounts in thousands):


	Three Months Ended June 30,						% Increase / (Decrease)	Six Months Ended June 30,						% Increase / (Decrease)

	2024			2023				2024			2023
Income tax expense	$	17,698		$	12,091		46%	$	22,359		$	5,153		100% +
Effective tax rate	48		%	32		%		45		%	45		%

The effective tax rates were 48% and 45% for the three and six months ended June 30, 2024, respectively. The effective tax rates were 32% and 45% for the three and six months ended June 30, 2023, respectively. Income tax expense represents the estimated annual effective tax rate applied to the year-to-date domestic operating results adjusted for certain discrete tax items.

The effective tax rates for the three and six months ended June 30, 2024 include costs related to non-deductible stock-based compensation, primarily related to expired stock options, and non-deductible executive compensation, partially offset by tax credits. The effective tax rates for the three and six months ended June 30, 2023 includes costs related to non-deductible stock-based compensation, a valuation allowance recorded against non-U.S. results and non-deductible executive compensation.

Liquidity and Capital Resources

Since our inception in 2006, we have devoted most of our cash resources to manufacturing, research and development and selling, general and administrative activities related to the development and commercialization of EXPAREL. In addition, we acquired ZILRETTA as part of the Flexion Acquisition in November 2021 and iovera° as part of the MyoScience Acquisition in April 2019. We are primarily dependent on the commercial success of EXPAREL and ZILRETTA. We have financed our operations primarily with the proceeds from the sale of convertible senior notes and other debt, common stock, product sales and collaborative licensing and milestone revenue. As of June 30, 2024, we had an accumulated deficit of $78.9 million, cash and cash equivalents and available-for-sale investments of $404.2 million and working capital of $539.5 million.

We expect that our cash and cash equivalents and available-for-sale investments on hand will be adequate to cover our short-term liquidity needs, and that we would be able to access other sources of financing should the need arise.

Summary of Cash Flows

The following table summarizes our cash flows from operating, investing and financing activities for the periods indicated (in thousands):


	Six Months Ended June 30,
Condensed Consolidated Statements of Cash Flows Data:	2024		2023
Net cash provided by (used in):
Operating activities	$	102,337	$	62,627
Investing activities	(30,745)		73,509
Financing activities	22,163		(153,465)
Net increase (decrease) in cash and cash equivalents	$	93,755	$	(17,329)

Operating Activities

During the six months ended June 30, 2024, net cash provided by operating activities was $102.3 million, compared to $62.6 million during the six months ended June 30, 2023. The increase of $39.7 million was attributable to increased revenue with favorable gross margins, lower interest paid and a $13.0 million payment made in the prior year for a termination fee relating to a licensing agreement.

Investing Activities

During the six months ended June 30, 2024, net cash used in investing activities was $30.7 million, which reflected $26.3 million of outflows from available-for-sale investment purchases (net of sales), as well as $4.4 million of capital expenditures for manufacturing product fill lines and for an EXPAREL capacity expansion project at our Science Center Campus in San Diego, California.

During the six months ended June 30, 2023, net cash provided by investing activities was $73.5 million, which reflected proceeds from $90.2 million of available-for-sale investment sales (net of purchases), partially offset by purchases of fixed assets of $10.0 million for fill lines for our products and equipment for an EXPAREL capacity expansion project at our Science Center Campus in San Diego, California and purchases of equity and debt investments of $6.8 million.

Financing Activities

During the six months ended June 30, 2024, net cash provided by financing activities was $22.2 million, which primarily consisted of $287.5 million in proceeds from the issuance of the 2029 Notes. We used the majority of the proceeds from the 2029 Notes to make a partial repurchase of the 2025 Notes in the amount of $191.0 million, enter into a capped call transaction for $26.7 million, repurchase $25.0 million of treasury stock, and pay debt issuance and financing costs of $9.4 million. Additionally, we paid the remaining $8.6 million of 3.375% convertible senior notes due 2024 assumed from the Flexion Acquisition (the “Flexion 2024 Notes”) upon their maturity and made $5.6 million of voluntary prepayments associated with the TLA Term Loan. See Note 8, Debt, to our condensed consolidated financial statements included herein for further discussion on the Flexion 2024 Notes, 2025 Notes, 2029 Notes, the capped call transaction and the TLA Term Loan. There was also $1.4 million of proceeds from the issuance of common stock through our ESPP.

Pacira BioSciences, Inc. | Q2 2024 Form 10-Q | Page 46

Table of Contents

During the six months ended June 30, 2023, net cash used in financing activities was $153.5 million, which consisted of a $296.9 million repayment of TLB Term Loan principal as well as a $5.8 million prepayment penalty in connection with the retirement of the TLB Term Loan facility, partially offset by the net proceeds from the TLA Term Loan of $149.6 million and the exercise of stock options of $1.9 million and $1.7 million from the issuance of common stock through our ESPP.

Debt

2028 Term Loan A Facility

On March 31, 2023, we entered into a credit agreement (as amended to date, the “TLA Credit Agreement”) to refinance the indebtedness outstanding under our TLB Credit Agreement (as defined and discussed below). The term loan issued under the TLA Credit Agreement (the “TLA Term Loan”) was issued at a 0.30% discount and provides for a single-advance term loan A facility in the principal amount of $150.0 million, which is secured by substantially all of our and any subsidiary guarantor’s assets and matures on March 31, 2028. We may elect to borrow either (i) alternate base rate borrowings or (ii) term benchmark borrowings or daily simple SOFR (as defined in the TLA Credit Agreement) borrowings. Each term loan borrowing which is an alternate base rate borrowing bears interest at a rate per annum equal to (i) the Alternate Base Rate (as defined in the TLA Credit Agreement), plus (ii) a spread based on our Senior Secured Net Leverage Ratio ranging from 2.00% to 2.75%. Each term loan borrowing which is a term benchmark borrowing or daily simple SOFR borrowing bears interest at a rate per annum equal to (i) the Adjusted Term SOFR Rate or Adjusted Daily Simple SOFR (as each is defined in the TLA Credit Agreement), plus (ii) a spread based on our Senior Secured Net Leverage Ratio ranging from 3.00% to 3.75%. During the six months ended June 30, 2024, we made voluntary principal prepayments of $5.6 million. During the year ended December 31, 2023, the Company made a scheduled principal payment of $2.8 million as well as $30.6 million of voluntary principal prepayments. Due to voluntary principal prepayments made, we are not required to make further principal payments until June 2026, although we retain the option to do so. As of June 30, 2024, borrowings under the TLA Term Loan consisted entirely of term benchmark borrowings at a rate of 8.43%.

The TLA Credit Agreement requires us to, among other things, maintain (i) a Senior Secured Net Leverage Ratio (as defined in the Credit Agreement), determined as of the last day of each fiscal quarter, of no greater than 3.00 to 1.00 and (ii) a Fixed Charge Coverage Ratio (as defined in the TLA Credit Agreement), determined as of the last day of each fiscal quarter, of no less than 1.50 to 1.00. The TLA Credit Agreement requires us to maintain an unrestricted cash and cash equivalents balance of at least $500.0 million less any prepayments of the 2025 Notes (as defined below) at any time from 91 days prior to the maturity date through the earlier of (i) the latest maturity date of the 2025 Notes and (ii) the date on which there is no outstanding principal amount of the 2025 Notes, which we expect to accomplish. The TLA Credit Agreement also contains customary affirmative and negative covenants, financial covenants, representations and warranties, events of default and other provisions. As of June 30, 2024, we were in compliance with all financial covenants under the TLA Credit Agreement. See Note 8, Debt, to our condensed consolidated financial statements included herein for further discussion.

2029 Convertible Senior Notes

In May 2024, we completed a private placement of $287.5 million in aggregate principal amount of our 2029 Notes, and entered into an indenture with respect to the 2029 Notes. The 2029 Notes accrue interest at a fixed rate of 2.125% per year, payable semiannually in arrears on May 15th and November 15th of each year. The 2029 Notes mature on May 15, 2029.

At June 30, 2024, all $287.5 million of principal was outstanding on the 2029 Notes. See Note 8, Debt, to our condensed consolidated financial statements included herein for further discussion.

2025 Convertible Senior Notes

In July 2020, we completed a private placement of $402.5 million in aggregate principal amount of our 2025 Notes, and entered into an indenture with respect to the 2025 Notes. The 2025 Notes accrue interest at a fixed rate of 0.750% per annum, payable semiannually in arrears on February 1st and August 1st of each year. The 2025 Notes mature on August 1, 2025.

In May 2024, we used part of the net proceeds from the issuance of the 2029 Notes to repurchase $200.0 million aggregate principal amount of the 2025 Notes in privately negotiated transactions at a discount for $191.4 million in cash (including accrued interest). The partial repurchase of the 2025 Notes resulted in a $7.5 million gain on early extinguishment of debt.

At June 30, 2024, the outstanding principal on the 2025 Notes was $202.5 million. See Note 8, Debt, to our condensed consolidated financial statements included herein for further discussion.

Future Capital Requirements

We believe that our existing cash and cash equivalents, available-for-sale investments and cash received from product sales will be sufficient to enable us to fund our operating expenses, capital expenditure requirements and payment of the interest and principal on our TLA Term Loan, 2025 Notes and 2029 Notes through the next 12 months. Our future use of operating cash and capital requirements will depend on many forward-looking factors, including, but not limited to:

•the cost and timing of the potential milestone payments to former Flexion stockholders, which could be up to an aggregate of $372.3 million if certain regulatory and commercial milestones are met. See Note 9, Financial Instruments, to our condensed consolidated financial statements included herein for more information;

•the impact of global economic conditions—including the impact of inflation—on our product, material and labor costs, supply chain, longer lead-times, an inability to secure a sufficient supply of materials, our operating expenses and our business strategy;

•the timing of and extent to which the holders of our 2025 Notes and 2029 Notes elect to convert their 2025 Notes and 2029 Notes, the timing of principal and interest payments on our TLA Term Loan and the timing and impact of increases to the variable interest rate on our TLA Term Loan borrowings in accordance with the terms of the TLA Credit Agreement;

•the costs and our ability to successfully continue to expand the commercialization of EXPAREL, ZILRETTA and iovera°;

•the cost and timing of expanding and maintaining our manufacturing facilities;

•the cost and timing of additional strategic investments, including additional investments under existing agreements;

•the costs related to legal and regulatory matters;

•the costs of performing additional clinical trials for our products, including the additional pediatric trials required by the FDA and EMA as a condition of the approval of EXPAREL;

•the costs for the development and commercialization of other product candidates;

•the costs and timing of future payments under our employee benefit plans, including but not limited to our cash long-term incentive plan and non-qualified deferred compensation plan;

•the timing and the number of shares of our common stock repurchased through our share repurchase program; and

•the extent to which we acquire or invest in products, businesses and technologies.

We may require additional debt or equity financing to meet our future operating and capital requirements. We have no committed external sources of funds, and additional equity or debt financing may not be available on acceptable terms, if at all. In particular, capital market disruptions or negative economic conditions may hinder our access to capital.

Critical Accounting Estimates

For a description of critical accounting policies that affect our significant judgments and estimates used in the preparation of our consolidated financial statements, refer to our 2023 Annual Report. There have been no significant changes to our critical accounting policies nor any recently issued accounting pronouncements that are expected to have a material impact on our financial results since December 31, 2023.

Contractual Obligations

There have been no material changes in our contractual obligations relating to our indebtedness, lease obligations and purchase obligations from those reported in our 2023 Annual Report. For more information on our contractual obligations and commercial commitments, see Part II, Item 7 in our 2023 Annual Report.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The primary objective of our cash equivalents and investment activities is to preserve principal while at the same time maximizing the income that we receive from our investments without significantly increasing risk. We invest in corporate bonds, commercial paper, asset-backed securities and U.S. Treasury and other government agency notes for purposes other than trading which are reported at fair value. These securities are subject to interest rate risk and credit risk. This means that a change in prevailing interest rates may cause the fair value of the investment to fluctuate. For example, if we hold a security that was issued with a fixed interest rate at the then-prevailing rate and the interest rate later rises, we expect that the fair value of our investment will decline. A hypothetical 100 basis point increase in interest rates would have reduced the fair value of our available-for-sale securities at June 30, 2024 by approximately $0.7 million.

The fair value of our 2025 Notes is impacted by both the fair value of our common stock and interest rate fluctuations. As of June 30, 2024, the estimated fair value of the 2025 Notes was $938 per $1,000 principal amount. See Note 8, Debt, to our condensed consolidated financial statements included herein for further discussion of our 2025 Notes, which bear interest at a fixed rate. At June 30, 2024, $202.5 million of principal remains outstanding on the 2025 Notes.

The fair value of our 2029 Notes is impacted by both the fair value of our common stock and interest rate fluctuations. As of June 30, 2024, the estimated fair value of the 2029 Notes was $996 per $1,000 principal amount. See Note 8, Debt, to our condensed consolidated financial statements included herein for further discussion of our 2029 Notes, which bear interest at a fixed rate. At June 30, 2024, $287.5 million of principal remains outstanding on the 2029 Notes.

The TLA Term Loan provides for a single-advance term loan in the principal amount of $150.0 million and is scheduled to mature on March 31, 2028. Each term loan borrowing that is a term benchmark borrowing or daily simple SOFR borrowing bears interest at a rate per annum equal to (i) the Adjusted Term SOFR Rate or Adjusted Daily Simple SOFR (as each is defined in the TLA Credit Agreement), plus (ii) a spread based on our Senior Secured Net Leverage Ratio ranging from 3.00% to 3.75%. At June 30, 2024, the outstanding principal on the TLA Term Loan was $110.9 million. As of June 30, 2024, borrowings under the TLA Term Loan consisted entirely of term benchmark borrowings at a rate of 8.43%. A hypothetical 100 basis point increase in interest rates would increase interest expense over the next 12 months by approximately $1.1 million, based on the balance outstanding for these borrowings as of June 30, 2024.

We have agreements with certain vendors and partners that operate in foreign jurisdictions. The more significant transactions are primarily denominated in the U.S. Dollar, subject to an annual adjustment based on changes in currency exchange rates.

Additionally, our accounts receivable are primarily concentrated with four large wholesalers of pharmaceutical products. In the event of non-performance or non-payment, there may be a material adverse impact on our financial condition, results of operations or net cash flow.

Item 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

As required by Rule 13a-15(b) under the Exchange Act, our management, including our Chief Executive Officer and our Chief Financial Officer, conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this report. As defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, disclosure controls and procedures are controls and other procedures which are designed to ensure that information required to be disclosed by us in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports we file or submit under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and our Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Based on that evaluation, our Chief Executive Officer and our Chief Financial Officer concluded that our disclosure controls and procedures were effective as of June 30, 2024.

Changes in Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting that occurred during the quarter ended June 30, 2024 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Pacira BioSciences, Inc. | Q2 2024 Form 10-Q | Page 49

Table of Contents

Inherent Limitations on Effectiveness of Controls

Our management, including the Chief Executive Officer and our Chief Financial Officer, does not expect that our disclosure controls or our internal control over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. The design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Further, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within our company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple errors or mistakes. Controls can also be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the controls. The design of any system of controls is based in part on 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. Projections of any evaluation of controls effectiveness to future periods are subject to risks. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures.

Item 1A. RISK FACTORS

You should carefully consider the factors discussed in Part I, Item 1A. “Risk Factors” in our 2023 Annual Report, which could materially affect our business, financial condition, cash flows or future results. There have been no material changes in our risk factors included in our 2023 Annual Report. The risks described in our 2023 Annual Report are not the only risks facing our Company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition or future results.

Item 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

Purchases of Equity Securities by the Registrant

The following table provides information on our share repurchases during the three months ended June 30, 2024:


	Issuer Purchases of Equity Securities

Total	837,240	$	29.86	837,240	$	125,000,000

(1) The average price paid per shares excludes $0.1 million of excise tax incurred on share repurchases for the three months ended June 30, 2024. The remaining authorization outstanding for repurchases of common stock also exclude the excise tax incurred.

(2) Our Board of Directors has authorized the repurchase of common stock under a share repurchase program adopted and announced in May 2024. The share repurchase program authorizes the Company to purchase up to an aggregate of $150.0 million of the Company’s outstanding common stock. Repurchases under this program may be made at management’s discretion on the open market or through privately negotiated transactions, including plans that comply with Rule 10b5-1 under the Exchange Act. The share repurchase program may be suspended or discontinued at any time by the Company and has an expiration date of December 31, 2026.

The timing of any repurchases and the actual number of shares repurchased will depend on a variety of factors, including our stock price, corporate and regulatory requirements, tax implications, restrictions under our debt obligations, other uses for capital, impacts on the value of remaining shares, and market and economic conditions.

Refer to Note 10, Stockholders’ Equity, to our condensed consolidated financial statements included herein for more information on our share repurchases.

DESCRIPTION OF BUSINESS	6 Months Ended
DESCRIPTION OF BUSINESS	Jun. 30, 2024
Organization, Consolidation and Presentation of Financial Statements [Abstract]
DESCRIPTION OF BUSINESS	DESCRIPTION OF BUSINESS Pacira BioSciences, Inc. and its subsidiaries (collectively, the “Company” or “Pacira”) is the therapeutic area leader in non-opioid pain management with a stated corporate mission of providing non-opioid pain management options to as many patients as possible and redefining the role of opioids for rescue therapy only. The Company’s long-acting, local analgesic, EXPAREL® (bupivacaine liposome injectable suspension), was commercially launched in the United States, or U.S., in April 2012 and approved in select European countries and the United Kingdom, or U.K., in November 2021. EXPAREL utilizes the Company’s proprietary multivesicular liposome, or pMVL, drug delivery technology that encapsulates drugs without altering their molecular structure and releases them over a desired period of time. In November 2021, the Company acquired Flexion Therapeutics, Inc., or Flexion (the “Flexion Acquisition”), and added ZILRETTA® (triamcinolone acetonide extended-release injectable suspension) to its product portfolio. ZILRETTA is the first and only extended-release, intra-articular (meaning in the joint) injection indicated for the management of osteoarthritis, or OA, knee pain. In April 2019, the Company added iovera°® to its commercial offering with the acquisition of MyoScience, Inc., or MyoScience (the “MyoScience Acquisition”). The iovera° system is a handheld cryoanalgesia device used to deliver a precise, controlled application of cold temperature to targeted nerves. Pacira is subject to risks common to companies in similar industries and stages, including, but not limited to, competition from larger companies, reliance on revenue from three products, reliance on a limited number of wholesalers, reliance on a limited number of manufacturing sites, new technological innovations, dependence on key personnel, reliance on third-party service providers and sole source suppliers, protection of proprietary technology, compliance with government regulations and risks related to cybersecurity. The Company is managed and operated as a single business focused on the development, manufacture, marketing, distribution and sale of non-opioid pain management and regenerative health solutions. The Company is managed by a single management team, and consistent with its organizational structure, the Chief Executive Officer—who is the Company’s chief operating decision maker—manages and allocates resources at a consolidated level. Effective January 2, 2024, the Company appointed a new Chief Executive Officer. Consistent with the Company’s predecessor chief operating decision maker, the Company views its business as one reportable operating segment to evaluate its performance, allocate resources, set operational targets and forecast its future financial results.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES From time to time, the Company has been and may again become involved in legal proceedings arising in the ordinary course of its business, including those related to its patents and intellectual property, product liability and government investigations. Except as described below, the Company is not presently a party to any legal proceedings that it believes to be material, and is not aware of any pending or threatened litigation against the Company which it believes could have a material adverse effect on its business, operating results, financial condition or cash flows. MyoScience Milestone Litigation In August 2020, the Company and its subsidiary, Pacira CryoTech, Inc. (“Pacira CryoTech”), filed a lawsuit in the Court of Chancery of the State of Delaware against Fortis Advisors LLC (“Fortis”), solely in its capacity as representative for the former securityholders of MyoScience, and certain other defendants, seeking declaratory judgment with respect to certain terms of the merger agreement for the MyoScience Acquisition (the “MyoScience Merger Agreement”), specifically related to the achievement of certain milestone payments under the MyoScience Merger Agreement. In addition, the Company and Pacira CryoTech sought general, special and compensatory damages against the other defendants related to breach of fiduciary duties in connection with the purported achievement of milestone payments under the MyoScience Merger Agreement, and breach of the MyoScience Merger Agreement and certain other agreements with the defendants. In October 2020, Fortis filed an answer and counterclaim against the Company and Pacira CryoTech seeking to recover certain milestone payments under the MyoScience Merger Agreement. The total remaining value of these milestones is $30.0 million, plus attorneys’ fees. A trial was conducted in September 2023, and a decision is expected in the coming weeks. The Company is unable to predict the outcome of this action at this time. eVenus Pharmaceutical Laboratories Litigations In October 2021, the Company received a Notice Letter advising that eVenus Pharmaceutical Laboratories, Inc., or eVenus, of Princeton, New Jersey, submitted to the United States Food and Drug Administration, or FDA, an Abbreviated New Drug Application, or ANDA with a Paragraph IV certification seeking authorization for the manufacturing and marketing of a generic version of EXPAREL (266 mg/20 mL) in the U.S. prior to the expiration of U.S. Patent No. 11,033,495 (the ‘495 patent). In November 2021, the Company filed a patent infringement suit against eVenus and its parent company in the U.S. District Court for the District of New Jersey (21-cv-19829) asserting infringement of the ‘495 patent. This triggered an automatic 30-month stay of final approval of the eVenus ANDA which expired on July 1, 2024. On January 6, 2022, eVenus filed an Answer with counterclaims to the Complaint, alleging the ‘495 patent is invalid and/or not infringed through the manufacture, sale, or offer for sale of the product described in eVenus’s ANDA submission. In December 2021, the Company received a second Notice Letter advising that eVenus submitted to the FDA an amendment to its ANDA with a Paragraph IV Certification seeking authorization for the manufacturing and marketing of a generic version of EXPAREL (133 mg/10 mL) in the U.S. prior to the expiration of the ‘495 patent. In the second Notice Letter, eVenus also advised that it submitted a Paragraph IV Certification to the FDA seeking authorization for the manufacturing and marketing of a generic version of EXPAREL (266 mg/20 mL and 133 mg/10 mL) in the U.S. prior to the expiration of U.S. Patent No. 11,179,336 (the ‘336 patent). eVenus further alleges in the Notice Letter that both the ‘495 patent and the ‘336 patent are invalid and/or not infringed. In February 2022, the Company filed a second patent infringement suit against eVenus and its parent company in the U.S. District Court for the District of New Jersey (22-cv-00718) asserting that the 133 mg/10 mL ANDA product will infringe the ‘495 and ‘336 patents and that the 266 mg/20 mL ANDA product will infringe the ‘336 patent. This filing triggered a second automatic 30-month stay of final approval for the 133 mg/10 mL ANDA product which expired on July 1, 2024. The first and second patent infringement suits were consolidated. In February 2023, eVenus filed its first amended answer to the first amended complaint, alleging patent invalidity, non-infringement and inequitable conduct. The Company has denied the allegations in eVenus’s first amended answer. The Company has subsequently voluntarily dismissed its claims with respect to the ‘336 Patent. The trial on the remaining claim was conducted in February 2024 with a decision expected in the coming days. In April 2023, the Company filed a third patent infringement suit against eVenus, its parent company, and Fresenius Kabi USA, LLC, or Fresenius, in the U.S. District Court for the District of New Jersey (23-cv-2367) asserting that the 133 mg/10 mL and 266 mg/20 mL ANDA products will infringe U.S. Patent No. 11,426,348 (the ‘348 patent). In July 2023, eVenus filed its answer with claims for declaratory judgment, alleging patent invalidity, non-infringement and inequitable conduct with respect to the ‘348 patent as well as the Company’s other patents, U.S. Patent Nos. 11,278,494; 11,304,904; 11,311,486; 11,357,727 and 11,452,691. The parties have subsequently dismissed all patents other than the ‘348 patent from this litigation. This action is in the discovery stage. In May 2024, the Company filed a fourth patent infringement suit against eVenus, its parent company and Fresenius in the U.S. District Court for the District of New Jersey (24-cv-6294) asserting that the 133 mg/10 mL and 266 mg/20 mL ANDA products will infringe U.S. Patent Nos. 11,819,574 and 11,819,575. This action is in the pleadings stage. In July 2024, the Company filed a fifth patent infringement suit against eVenus, its parent company and Fresenius in the U.S. District Court for the District of New Jersey (24-cv-7680) asserting that the 133 mg/10 mL and 266 mg/20 mL ANDA products will infringe U.S. Patent No. 11,925,706. This action is in the pleadings stage. The Company is unable to predict the outcome of these litigations at this time. Research Development Foundation Pursuant to an agreement with the Research Development Foundation, or RDF, the Company was required to pay RDF a low single-digit royalty on the collection of revenues from certain products, for as long as certain patents assigned to the Company under the agreement remain valid. RDF has the right to terminate the agreement for an uncured material breach by the Company, in connection with its bankruptcy or insolvency or if it directly or indirectly opposes or disputes the validity of the assigned patent rights. The Company’s ‘495 patent was issued on June 15, 2021. Thereafter, RDF asserted that the issuance of that patent extends the Company’s royalty obligations under the agreement until 2041. The Company believes that the royalty period under the agreement ended on December 24, 2021 with the expiration of its U.S. Patent No. 9,585,838. Because of the disagreement over the interpretation of the agreement, in December 2021, the Company filed a declaratory judgment lawsuit in the U.S. District Court for the District of Nevada (21-cv-02241). The lawsuit seeks a declaration from the court that the Company owes no royalties to RDF with respect to its EXPAREL product after December 24, 2021. On August 8, 2023, the U.S. District Court, District of Nevada, granted the Company’s motion for partial summary judgment in respect to the Company’s claim for a declaration that it no longer owes royalties for EXPAREL made under the 45-liter manufacturing process as of December 24, 2021. As a result, the Company expects to receive $14.5 million from RDF, representing the royalties that the Company paid to RDF under protest after December 24, 2021 for EXPAREL made from the 45-liter manufacturing process. Once it becomes probable that the settlement amount will be received, the Company will record a settlement gain within other operating income (expense), net in the condensed consolidated statement of operations. In November 2023, the U.S. District Court, District of Nevada conducted a mediation that did not result in a settlement. During the pendency of the remaining lawsuit, the Company will continue to pay royalties associated with the 200-liter EXPAREL manufacturing process to RDF under protest. A trial is currently scheduled for September 2024. The Company is unable to predict the outcome of this action at this time. Other Commitments and Contingencies Pediatric Trial Commitments The FDA, as a condition of EXPAREL approval, has required the Company to study EXPAREL for infiltration and as a brachial plexus block in pediatric patients. The Company was granted deferrals for the required pediatric trials until after the indications were approved in adults. Similarly, in Europe, the Company agreed with the European Medicines Agency, or EMA, on a Pediatric Investigation Plan as a prerequisite for submitting a Marketing Authorization Application (MAA) in the E.U. Despite the U.K.’s withdrawal from the E.U., the agreed pediatric plan is applicable in the U.K. The Company received notification from the FDA in October 2023 that its pediatric studies requirement had been waived for the indication of brachial plexus interscalene nerve block to produce postsurgical regional analgesia in pediatric patients. The Company is still working with the FDA, EMA and Medicines and Healthcare Regulatory Agency (MHRA) to finalize the regulatory pathways for its remaining pediatric commitments. Contingent Milestone Payments Refer to Note 9, Financial Instruments, for information on potential contingent milestone payments related to the Flexion Acquisition. PCRX-201 PCRX-201, a novel, intra-articular gene therapy product candidate that produces the anti-inflammatory protein interleukin-1 receptor antagonist (IL-1Ra) treating OA pain in the knee, was added to the Company’s portfolio as part of the Flexion Acquisition in November 2021. Prior to the Flexion Acquisition, in February 2017, Flexion entered into an agreement with GQ Bio Therapeutics GmbH to acquire the global rights to PCRX-201, a gene therapy product candidate. As part of the agreement, up to an aggregate of $56.0 million of payments could become due upon the achievement of certain development and regulatory milestones, including up to $4.5 million through initiation of a Phase 2 proof of concept clinical trial and, following successful proof of concept, up to an additional $51.5 million in development and global regulatory approval milestone payments. In February 2024, the FDA granted a Regenerative Medicine Advanced Therapy (RMAT) designation to PCRX-201 for the treatment of OA pain of the knee.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	Jun. 30, 2024
Accounting Policies [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation These interim condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America, or GAAP, and in accordance with the rules and regulations of the United States Securities and Exchange Commission (the “SEC”), for interim reporting. Pursuant to these rules and regulations, certain information and footnote disclosures normally included in complete annual financial statements have been condensed or omitted. Therefore, these interim condensed consolidated financial statements should be read in conjunction with the audited annual consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 (the “2023 Annual Report”). The condensed consolidated financial statements at June 30, 2024, and for the three and six-month periods ended June 30, 2024 and 2023, are unaudited, but include all adjustments (consisting of only normal recurring adjustments) which, in the opinion of management, are necessary to present fairly the financial information set forth herein in accordance with GAAP. The condensed consolidated balance sheet at December 31, 2023 is derived from the audited consolidated financial statements included in the Company’s 2023 Annual Report. The condensed consolidated financial statements as presented reflect certain reclassifications from previously issued financial statements to conform to the current year presentation. The accounts of wholly-owned subsidiaries are included in the condensed consolidated financial statements. Intercompany accounts and transactions have been eliminated in consolidation. The results of operations for these interim periods are not necessarily indicative of results that may be expected for any other interim periods or for the full year.
Concentration of Major Customers	Concentration of Major Customers The Company sells EXPAREL through a drop-ship program under which orders are processed through wholesalers (including AmerisourceBergen Health Corporation, Cardinal Health, Inc. and McKesson Drug Company), but shipments of the product are sent directly to individual accounts, such as hospitals, ambulatory surgery centers and individual physicians.
Recent Accounting Pronouncements Not Adopted as of June 30, 2024	Recent Accounting Pronouncements Not Adopted as of June 30, 2024 In November 2023, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, 2023-07, Segment Reporting (Topic 280), Improvements to Reportable Segment Disclosures. The ASU amendment improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses on an interim and annual basis. The new segment disclosure requirements apply for entities with a single reportable segment. The ASU’s amendments are effective for fiscal years beginning after December 15, 2023 and interim periods thereafter, with early adoption permitted. The ASU amendment will require adoption on a retrospective basis. The Company is currently evaluating the impact of adopting ASU 2023-07 on its consolidated financial statements. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740), Improvements to Income Tax Disclosures. The ASU amendment addresses investor requests for more transparency about income tax information through improvements to income tax disclosures primarily related to the rate reconciliation and income taxes paid information. The ASU’s amendments are effective for fiscal years beginning after December 15, 2024 and may be adopted on a prospective or retrospective basis. The Company is currently evaluating the impact of adopting ASU 2023-09 on its consolidated financial statements.
