CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

NOTE 1—DESCRIPTION OF BUSINESS

Pacira BioSciences, Inc. and its subsidiaries (collectively, the “Company” or “Pacira”) is the industry leader in its commitment to non-opioid pain management and regenerative health solutions to improve patients’ journeys along the neural pain pathway. The Company’s long-acting, local analgesic, EXPAREL® (bupivacaine liposome injectable suspension), was commercially launched in the United States in April 2012 and approved by the European Commission in November 2020. EXPAREL utilizes DepoFoam®, a unique and proprietary delivery technology that encapsulates drugs without altering their molecular structure, and releases them over a desired period of time. In April 2019, the Company added iovera°® to its commercial offering with the acquisition of MyoScience, Inc., or MyoScience. The iovera° system is a handheld cryoanalgesia device used to deliver a precise, controlled application of cold temperature to only 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 two products, 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 and Chairman manages and allocates resources at a consolidated level. Accordingly, the Company views its business as one reportable segment to evaluate performance, allocate resources, set operational targets and forecast its future financial results.

Novel Coronavirus (COVID-19) Pandemic

During 2020 and thus far in 2021, the Company’s net product sales were negatively impacted by the global pandemic caused by a novel strain of coronavirus (COVID-19), which mandated significant postponement or suspension in the scheduling of elective surgical procedures resulting from public health guidance and government directives. Elective surgical restrictions began to lift on a state-by-state basis in April 2020; however, while many restrictions have since eased as COVID-19 vaccines become more widely available and administered to the general public, the Company still does not know how long it will take the elective surgical market to normalize, or if restrictions on elective surgical procedures will recur. The Company’s manufacturing sites are operational and have implemented new safety protocols and guidelines as recommended by federal, state and local governments. To date, there have been no material impacts to the Company’s supply chain. The situation remains dynamic and subject to rapid and possibly material changes. Additional negative impacts may also arise from the COVID-19 pandemic that the Company is unable to foresee. The nature and extent of such impacts will depend on future developments, which are highly uncertain and cannot be predicted.

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 (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, 2020.

The condensed consolidated financial statements at March 31, 2021, and for the three-month periods ended March 31, 2021 and 2020, 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, 2020 is derived from the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020. The condensed consolidated financial statements as presented reflect certain reclassifications from previously issued financial statements to conform to the

Pacira BioSciences, Inc. | Q1 2021 Form 10-Q | Page 9

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 doctors. The Company also sells EXPAREL directly to ambulatory surgery centers and physicians. The Company sells its bupivacaine liposome injectable suspension for veterinary use to a third-party licensee and sells iovera° directly to end users. The table below includes the percentage of revenues comprised by the Company’s three largest wholesalers in each period presented:

	Three Months Ended March 31,
	2021	2020
Largest wholesaler	32%	32%
Second largest wholesaler	29%	31%
Third largest wholesaler	27%	26%
Total	88%	89%

Recently Adopted Accounting Pronouncements

In December 2019, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, 2019-12, Income Taxes (Topic 740), Simplifying the Accounting for Income Taxes, which amended the approaches and methodologies in accounting for income taxes during interim periods and makes changes to certain income tax classifications. The new standard now allows for certain exceptions, including an exception to the use of the incremental approach for intra-period tax allocations, when there is a loss from continuing operations and income or a gain from other items, and to the general methodology for calculating income taxes in an interim period, when a year-to-date loss exceeds the anticipated loss for the year. The standard also requires franchise or similar taxes partially based on income to be reported as income tax and to reflect the effects of enacted changes in tax laws or rates in the annual effective tax rate computation from the date of enactment. Lastly, in any future acquisition, the Company would be required to evaluate when the step-up in the tax basis of goodwill is part of the business combination and when it should be considered a separate transaction. The standard became effective for the Company beginning January 1, 2021, and there were no material impacts to the consolidated financial statements upon adoption.

Recent Accounting Pronouncements Not Adopted as of March 31, 2021

In August 2020, the FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40), which limits the number of convertible instruments that require separate accounting to (i) those with embedded conversion features that are not clearly and closely related to the debt, that meet the definition of a derivative, and that do not qualify for the scope exception from derivative accounting and (ii) convertible debt instruments issued with substantial premiums for which the premiums are recorded as paid-in capital. In addition, the new guidance requires diluted earnings per share calculations to be prepared using the if-converted method, instead of the treasury stock method. The guidance must be applied in fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. The Company has the option to adopt the new guidance using a modified retrospective method of transition, which would then be applied to transactions outstanding at the time of adoption, or the full retrospective method. The Company is evaluating the impact from the adoption of ASU 2020-06 on its consolidated financial statements.

Pacira BioSciences, Inc. | Q1 2021 Form 10-Q | Page 10

NOTE 3—REVENUE

Revenue from Contracts with Customers

The Company’s sources of revenue include (i) sales of EXPAREL in the United States, or U.S.; (ii) sales of iovera° in the U.S.; (iii) sales of, and royalties on, its bupivacaine liposome injectable suspension for veterinary use in the U.S. and (iv) license fees and milestone payments. To date, there has been no revenue from sales of EXPAREL or iovera° in the European Union, or E.U. The Company does not consider revenue from sources other than sales of EXPAREL to be material to its consolidated revenue. As such, the following disclosure only relates to revenue associated with net EXPAREL product sales.

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. Product revenue is recognized when control of the promised goods are transferred to the customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for transferring those goods. EXPAREL revenue is recorded at the time the product is delivered to the end-user.

Revenues from sales of products are recorded net of returns allowances, prompt payment discounts, wholesaler service fees, 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 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. The calculation of some of these items requires management to make estimates based on sales data, historical return data, contracts 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 and doctors. Payment terms generally range from zero to 37 days 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 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.

Disaggregated Revenue

The following table represents disaggregated net product sales in the periods presented as follows (in thousands):

As of both March 31, 2021 and December 31, 2020, the Company had asset retirement obligations of $2.0 million, which are included in accrued expenses and other liabilities on its condensed consolidated balance sheet, for costs associated with returning leased spaces to their original condition upon the termination of certain lease agreements.

NOTE 6—LEASES

The Company leases all of its facilities, including its EXPAREL manufacturing facility in San Diego, California and its iovera° manufacturing facility in Fremont, California. These leases have remaining terms up to 9.4 years, some of which provide renewal options at the then-current market value. The Company also has an embedded lease with Thermo Fisher Scientific Pharma Services, for the use of their manufacturing facility in Swindon, England. A portion of the associated monthly base fees has been allocated to the lease component based on a relative fair value basis.

Pacira BioSciences, Inc. | Q1 2021 Form 10-Q | Page 12

NOTE 7—GOODWILL AND INTANGIBLE ASSETS

Goodwill

The Company’s goodwill results from the acquisition of Pacira Pharmaceuticals, Inc. (the Company’s California operating subsidiary) from SkyePharma Holding, Inc. (now a subsidiary of Vectura Group plc), or Skyepharma in March 2007 (the “Skyepharma Acquisition”), and the acquisition of MyoScience, Inc. (the “MyoScience Acquisition”) in April 2019.

There was no change in the carrying value of the Company’s goodwill during the three months ended March 31, 2021. The balance at both March 31, 2021 and December 31, 2020 was $99.5 million.

Pacira BioSciences, Inc. | Q1 2021 Form 10-Q | Page 13

The Skyepharma Acquisition occurred in March 2007, prior to the requirements to record contingent consideration at fair value under ASC 805-30. In connection with the Skyepharma Acquisition, the Company agreed to certain milestone payments for DepoBupivacaine products, including EXPAREL. As of March 31, 2021, the remaining milestone payments include: $4.0 million upon the first commercial sale in the United Kingdom, France, Germany, Italy or Spain; and $32.0 million when annual net sales collected reach $500.0 million (measured on a rolling quarterly basis). Any remaining milestone payments will be treated as additional costs of the Skyepharma Acquisition and, therefore, recorded as goodwill if and when each contingency is resolved.

In connection with the MyoScience Acquisition, the Company recorded goodwill totaling $37.5 million. The Company made a tax election that allows the acquired goodwill and intangible assets associated with the MyoScience Acquisition to be tax deductible.

Intangible Assets

Intangible assets, net, consist of the developed technology and customer relationships that were acquired in the MyoScience Acquisition and are summarized as follows (in thousands):

	Estimated Useful Life	March 31,		December 31,
		2021		2020
Developed technology	14 years	$	110,000	$	110,000
Customer relationships	10 years	90		90
Total intangible assets		110,090		110,090
Less: accumulated amortization		(15,536)		(13,569)
Intangible assets, net		$	94,554	$	96,521

Amortization expense on intangible assets for both the three months ended March 31, 2021 and 2020 was $2.0 million.

Assuming no changes in the gross carrying amount of these intangible assets, amortization expense will be $5.9 million for the remaining nine months of 2021, $7.9 million annually through 2032 and $2.2 million in 2033.

NOTE 8—DEBT

Convertible Senior Notes Due 2025

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, 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.

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

	March 31,		December 31,
	2021		2020
0.750% convertible senior notes due 2025	$	402,500	$	402,500
Deferred financing costs	(8,502)		(8,940)
Discount on debt	(76,660)		(80,530)
Total debt, net of debt discount and deferred financing costs	$	317,338	$	313,030

The net proceeds from the issuance of the 2025 Notes were approximately $390.0 million, after deducting commissions and the offering expenses paid by the Company. A portion of the net proceeds from the 2025 Notes was used by the Company to repurchase $185.0 million in aggregate principal amount of its outstanding 2.375% convertible senior notes due 2022 in privately-negotiated transactions for a total of $211.1 million of cash (including accrued interest).

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 under the following circumstances:

Pacira BioSciences, Inc. | Q1 2021 Form 10-Q | Page 14

(i) during any calendar quarter (and only during such calendar quarter), if the last reported sale price of the Company’s 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 greater than or equal to 130% of the conversion price on each applicable trading day;

(ii) during the five business day period immediately after any five consecutive trading day period (the “measurement period”) in which the trading price (as defined in the 2025 Indenture) per $1,000 principal amount of 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;

(iii) upon the occurrence of specified corporate events, including a merger or a sale of all or substantially all of the Company’s assets; or

(iv) if the Company calls the 2025 Notes for redemption, until the close of business on the business day immediately preceding the redemption date.

During the quarter ended March 31, 2021, none of these conditions for conversion were met.

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 March 31, 2021, the 2025 Notes had a market price of $1,200 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 $402.5 million in principal value and any conversion premium in any combination of cash and shares of its common stock (at the Company’s option).

Prior to August 1, 2023, the Company may not redeem the 2025 Notes. On or after 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.

If the Company undergoes a fundamental change, as defined in the 2025 Indenture, subject to certain conditions, holders of the 2025 Notes may require the Company to repurchase for cash all or part of their 2025 Notes at a repurchase price equal to 100% of the principal amount of the 2025 Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date. In addition, if a “make-whole fundamental change” (as defined in the 2025 Indenture) occurs prior to August 1, 2025, the Company will, in certain circumstances, increase the conversion rate for a holder who elects to convert its notes in connection with the make-whole fundamental change.

Pacira BioSciences, Inc. | Q1 2021 Form 10-Q | Page 15

The 2025 Notes are the Company’s general unsecured obligations that rank senior in right of payment to all of its indebtedness that is expressly subordinated in right of payment to the 2025 Notes, and equal in right of payment to the Company’s unsecured indebtedness. The 2025 Notes are also effectively junior in right of payment to any of the Company’s secured indebtedness to the extent of the value of the assets securing such indebtedness, and are structurally subordinated to any debt or other liabilities (including trade payables) of the Company’s subsidiaries.

While the 2025 Notes are currently classified on the Company’s consolidated balance sheet at March 31, 2021 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.

Under ASC 470-20, Debt with Conversion and Other Options, an entity must separately account for the liability and equity components of convertible debt instruments (such as the 2025 Notes) that may be settled entirely or partially in cash upon conversion in a manner that reflects the issuer’s economic interest cost. The liability component of the instrument is valued in a manner that reflects the market interest rate for a similar nonconvertible instrument at the date of issuance. The initial carrying value of the liability component of $314.7 million was calculated using a 5.78% assumed borrowing rate. The equity component of $87.8 million, representing the conversion option, was determined by deducting the fair value of the liability component from the par value of the 2025 Notes and is recorded in additional paid-in capital on the consolidated balance sheet at the issuance date. The equity component is treated as a discount on the liability component of the 2025 Notes, which is amortized over the five-year term of the 2025 Notes using the effective interest rate method. The equity component is not re-measured as long as it continues to meet the conditions for equity classification. A deferred tax liability was recognized in the amount of $20.5 million, with the offsetting amount recorded in additional paid-in capital.

The Company allocated the total transaction costs of approximately $12.5 million related to the issuance of the 2025 Notes to the liability and equity components of the 2025 Notes based on their relative values. Transaction costs attributable to the liability component are amortized to interest expense over the five-year term of the 2025 Notes, and transaction costs attributable to the equity component totaling $2.7 million are netted with the equity component in stockholders’ equity.

The 2025 Notes do not contain any financial or operating covenants or any restrictions on the payment of dividends, the issuance of other indebtedness or the issuance or repurchase of securities by the Company. The 2025 Indenture contains customary events of default with respect to the 2025 Notes, including that upon certain events of default, 100% of the principal and accrued and unpaid interest on the 2025 Notes will automatically become due and payable.

Convertible Senior Notes Due 2022

In March 2017, the Company completed a private placement of $345.0 million in aggregate principal amount of 2.375% convertible senior notes due 2022, or 2022 Notes, and entered into an indenture, or 2022 Indenture, with respect to the 2022 Notes. The 2022 Notes accrue interest at a fixed rate of 2.375% per year, payable semiannually in arrears on April 1st and October 1st of each year. The 2022 Notes mature on April 1, 2022. As discussed above, in July 2020, the Company used part of the net proceeds from the issuance of the 2025 Notes to repurchase $185.0 million aggregate principal amount of the 2022 Notes in privately-negotiated transactions for an aggregate of $211.1 million in cash (including accrued interest). The partial repurchase of the 2022 Notes resulted in an $8.1 million loss on early extinguishment of debt.

The total debt composition of the 2022 Notes is as follows (in thousands):

	March 31,		December 31,
	2021		2020
2.375% convertible senior notes due 2022	$	160,000	$	160,000
Deferred financing costs	(876)		(1,089)
Discount on debt	(7,477)		(9,263)
Total debt, net of debt discount and deferred financing costs	$	151,647	$	149,648

Holders may convert their 2022 Notes prior to October 1, 2021 only if certain circumstances are met, including if during the previous calendar quarter, the last reported sales price of the Company’s common stock was greater than or equal to 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 March 31, 2021, this condition for conversion was not met.

Pacira BioSciences, Inc. | Q1 2021 Form 10-Q | Page 16

On or after October 1, 2021, until the close of business on the second scheduled trading day immediately preceding April 1, 2022, holders may convert their 2022 Notes at any time.

Upon conversion, holders will receive the principal amount of their 2022 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 2022 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 2022 Notes is 14.9491 shares of common stock per $1,000 principal amount, which is equivalent to an initial conversion price of $66.89 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 2022 Notes represents a premium of approximately 37.5% to the closing sale price of $48.65 per share of the Company’s common stock on the Nasdaq Global Select Market on March 7, 2017, the date that the Company priced the private offering of the 2022 Notes.

As of March 31, 2021, the 2022 Notes had a market price of $1,216 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 stock price appreciation. Upon the receipt of conversion requests, the settlement of the 2022 Notes will be paid pursuant to the terms of the 2022 Indenture. In the event that all of the 2022 Notes are settled, the Company would be required to repay the remaining $160.0 million in principal value and any conversion premium in any combination of cash and shares of its common stock (at the Company’s option).

As of April 1, 2020, the Company may redeem for 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, all or part of the 2022 Notes if the last reported sale price (as defined in the 2022 Indenture) of the Company’s common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading-day period ending within five trading days prior to the date on which the Company provides notice of redemption. This condition was not met during the quarter ended March 31, 2021. The redemption price will equal the sum of (i) 100% of the principal amount of the 2022 Notes being redeemed, plus (ii) accrued and unpaid interest, including additional interest, if any, to, but excluding, the redemption date. In addition, calling the 2022 Notes for redemption will constitute a “make-whole fundamental change” (as defined in the 2022 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 2022 Notes.

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:

Pacira BioSciences, Inc. | Q1 2021 Form 10-Q | Page 17

•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 equity investment with a readily determinable fair value is calculated utilizing market quotations from a major American stock exchange (Level 1). The fair value of the Company’s convertible senior notes 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 amount of the investment without a readily determinable fair value has not been adjusted for either an impairment or upward or downward adjustments based on observable transactions. Certain assets and liabilities are measured at fair value on a non-recurring basis, including assets and liabilities acquired in a business combination and long-lived assets, which would be recognized at fair value if deemed impaired or if reclassified as assets held for sale. The fair value in these instances would be determined using Level 3 inputs.

At March 31, 2021, the carrying values and fair values of the following financial assets and liabilities was as follows (in thousands):

	Carrying Value		Fair Value Measurements Using
			Level 1		Level 2		Level 3
Financial Assets and Financial Liabilities Measured at Fair Value on a Recurring Basis:
Financial Assets:
Equity investment with readily determinable fair value	$	11,533	$	11,533	$	—	$	—

(1) The closing price of the Company’s common stock as reported on the Nasdaq Global Select Market was $70.09 per share on March 31, 2021, compared to a conversion price of $66.89 per share for the 2022 Notes and $71.78 per share for the 2025 Notes. The maximum conversion premium that could have been due on the 2022 Notes and 2025 Notes at March 31, 2021 was approximately 2.4 million and 5.6 million shares of the Company’s common stock, respectively. These figures assume no increases in the conversion rate for certain corporate events.

Equity and Debt Investments

At March 31, 2021 and December 31, 2020, the Company held an equity investment in TELA Bio, Inc., or TELA Bio, in its condensed consolidated balance sheets in the amounts of $11.5 million and $11.6 million, respectively. For the three months ended March 31, 2021 and 2020, the fair value of this publicly traded investment decreased by $0.1 million and $4.0 million, respectively, which was recorded in other, net in the condensed consolidated statement of operations. The fair values of TELA Bio at March 31, 2021 and December 31, 2020 were based on Level 1 inputs.

At March 31, 2021 and December 31, 2020, the Company held an equity investment of $1.2 million in GeneQuine Biotherapeutics GmbH, or GeneQuine, a privately held biopharmaceutical company headquartered in Hamburg, Germany. This investment has no readily determinable fair value and is recorded at cost minus impairment, if any, plus or minus observable price changes of identical or similar investments. In January 2021 the Company purchased a convertible note from GeneQuine in the amount of $1.2 million. There were no adjustments recognized in the GeneQuine investments during the three months ended March 31, 2021.The Company has the right to make additional investments in both equity and debt securities of $4.7 million predicated upon GeneQuine achieving certain prespecified near-term milestones.

Acquisition-related Contingent Consideration

In April 2019, the Company completed the MyoScience Acquisition pursuant to the terms of an Agreement and Plan of Merger, which provided for contingent milestone payments of up to an aggregate of $100.0 million upon the achievement of certain regulatory and commercial milestones. The Company’s obligation to make milestone payments is limited to those milestones achieved through December 31, 2023, and are to be paid within 60 days of the end of the fiscal quarter of achievement. As of March 31, 2021, the maximum potential remaining milestone payments are $58.0 million. The Company made no milestone payments during the three months ended March 31, 2021. In the three months ended March 31, 2020, the Company made a $5.0 million cash payment for the achievement of one regulatory milestone. A regulatory milestone in the amount of $10.0 million is payable during the second quarter of 2021. As of March 31, 2021 and December 31, 2020, the Company has recognized contingent consideration related to the MyoScience Acquisition in the amounts of $27.2 million and $28.3 million, 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. In the three month periods ended March 31, 2021 and 2020, the Company recognized $1.1 million and $3.9 million of gains, respectively, which have been included in acquisition-related gains in the condensed consolidated statements of operations. 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 rate 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. At March 31, 2021, the weighted average discount rate was 3.66% and the weighted average probability of success for regulatory milestones that have not yet been met was 34.7%.

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

Assumption	Ranges Utilized as of March 31, 2021
Discount rates	3.50% to 3.82%
Probabilities of payment for regulatory milestones	2% to 100%
Projected years of payment for regulatory and commercial milestones	2021 to 2023

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

	Contingent Consideration Fair Value
Balance at December 31, 2020	$	28,346

Investments

Short-term investments consist of asset-backed securities collateralized by credit card receivables, investment grade commercial paper and corporate and government bonds with maturities greater than three months, but less than one year. Long-term investments consist of asset-backed securities collateralized by credit card receivables and government bonds with 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 and long-term investments are reported in other comprehensive income (loss). At March 31, 2021, all of the Company’s short-term and long-term investments are classified as available-for-sale investments and are determined to be Level 2 instruments, 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. At the time of purchase, all short-term and long-term investments had an “A” or better rating by Standard & Poor’s.

At March 31, 2021, 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 March 31, 2021 and December 31, 2020, the interest receivable recognized in prepaid expenses and other current assets was $0.8 million and $1.6 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 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 March 31, 2021, three wholesalers each accounted for over 10% of the Company’s accounts receivable, at 35%, 27% and 26%. At December 31, 2020, three wholesalers each accounted for over 10% of the Company’s accounts receivable, at 36%, 28% and 23%. For additional information regarding the Company’s wholesalers, see Note 2, Summary of Significant Accounting Policies. EXPAREL revenues are primarily derived from major wholesalers 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 March 31, 2021 and December 31, 2020, the Company did not deem any allowances for credit losses on its accounts receivable necessary.

Employee Stock Purchase Plan

The Company’s 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 less. During the three months ended March 31, 2021, no shares were purchased and issued through the ESPP.

NOTE 12—NET INCOME (LOSS) PER SHARE

Basic net income (loss) per share is calculated by dividing the net income (loss) attributable to common shares by the weighted average number of common shares outstanding during the period. Diluted net income (loss) per common share is calculated by dividing the net income (loss) 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, the purchase of shares from the ESPP (using the treasury stock method) and the conversion of the excess conversion value on the 2022 Notes and 2025 Notes. As discussed in Note 8, Debt, the Company has the option to pay cash for the aggregate principal amount due upon the conversion of its 2022 Notes and 2025 Notes. Since it is the Company’s intent to settle the principal amount of its 2022 Notes and 2025 Notes in cash, the potentially dilutive effect of such notes on net income (loss) per share is computed under the treasury stock method. ASU 2020-06 will require the Company to use the if-converted method upon adoption; this new accounting pronouncement has not been adopted as of March 31, 2021.

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

The following table sets forth the computation of basic and diluted net income per share for the three months ended March 31, 2021 and 2020 (in thousands, except per share amounts):

NOTE 13—INCOME TAXES

Income (loss) before income taxes is as follows (in thousands):

	Three Months Ended March 31,
	2021		2020
Income (loss) before income taxes:
Domestic	$	15,933	$	9,821
Foreign	(3,209)		(1,264)
Total income before income taxes	$	12,724	$	8,557

For the three months ended March 31, 2021 and 2020, the Company had income tax expense of $2.4 million and $0.4 million, respectively. The income tax expense for the three months ended March 31, 2021 represents the estimated annual effective tax rate applied to the year-to-date domestic operating results adjusted for certain discrete tax benefits related to equity compensation. The income tax expense for the three months ended March 31, 2020 consisted primarily of state income taxes in jurisdictions where the availability of carryforward losses were either limited or fully utilized.

During the year ended December 31, 2020, the Company determined that there was sufficient positive evidence to conclude that it was more likely than not that domestic deferred taxes were realizable and, therefore, released the valuation allowance. The Company continues to maintain a full valuation allowance on its foreign net deferred tax balances.

NOTE 14—COMMERCIAL PARTNERS

Nuance Biotech Co. Ltd.

In June 2018, the Company entered an agreement with Nuance Biotech Co. Ltd., or Nuance, a China-based specialty pharmaceutical company, to advance the development and commercialization of EXPAREL in China. Under the terms of the agreement, the Company had granted Nuance the exclusive rights to develop and commercialize EXPAREL. In April 2021, Pacira and Nuance agreed to a mutual termination of the agreement due to the lack of a viable regulatory pathway that adequately safeguards the Company’s intellectual property against the risk of a generic product. Estimated dissolution costs of $3.0 million have been included in other operating expenses in the condensed consolidated statements of operations for the three months ended March 31, 2021.

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 patents, 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 “Merger Agreement”), specifically related to the achievement of certain milestone payments under the 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 Merger Agreement, and breach of the 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 Merger Agreement totaling $40.0 million, and attorneys’ fees. The Company believes that the counterclaim from Fortis is without merit and intends to vigorously defend against all claims. The Company is unable to predict the outcome of this action at this time.

Other Commitments and Contingencies

The United States Food and Drug Administration, or FDA, as a condition of EXPAREL approval, has required the Company to study EXPAREL in pediatric patients. The Company was granted a deferral for the required pediatric trials in all age groups for EXPAREL in the setting of wound infiltration and is conducting these pediatric trials as post-marketing requirements, as stated in the New Drug Application (NDA) approval letter for EXPAREL. Similarly, in Europe, the Company agreed with the European Medicines Agency, or EMA, on a Pediatric Investigation Plan, or PIP, as a prerequisite for submitting a Marketing Authorization Application (MAA) in the E.U. Despite the United Kingdom’s withdrawal from the E.U. (“Brexit”), the PIP will be applicable in the United Kingdom as well.

In December 2019, the Company announced positive results for its extended pharmacokinetic and safety study for local analgesia in children aged 6 to 17 undergoing cardiovascular or spine surgeries. Those positive results provided the foundation for a supplemental New Drug Application, or sNDA, and in March 2021, the Company announced that the FDA approved the submission of the sNDA seeking expansion of the EXPAREL label to include use in patients 6 years of age and older for single-dose infiltration to produce postsurgical local analgesia. The Company is working with both the FDA and EMA to harmonize its pediatric clinical studies as much as possible between the two regions.

NOTE 16—SUBSEQUENT EVENTS        

In April 2021, the Company made cash investments of $13.0 million in debt and equity securities of two separate pre-clinical stage biopharmaceutical companies. The Company intends to make an additional $7.0 million investment if and when certain events occur.

Overview

Pacira is the industry leader in our commitment to non-opioid pain management and regenerative health solutions to improve patients’ journeys along the neural pain pathway. EXPAREL, our long-acting, local analgesic was commercially launched in April 2012. EXPAREL utilizes DepoFoam, a unique and proprietary delivery technology that encapsulates drugs without altering their molecular structure and releases them over a desired period of time. EXPAREL is indicated in patients 6 years of age and older for single-dose infiltration to produce postsurgical local analgesia, and in adults as an interscalene brachial plexus nerve block to produce postsurgical regional analgesia in the U.S., and in the E.U. 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. Since its initial approval in 2011 for single-dose infiltration, more than eight million patients have been treated with EXPAREL. We drop-ship EXPAREL directly to the end-user based on orders

placed to wholesalers or directly to us, and there is no product held by wholesalers. In April 2019, we acquired iovera°, a handheld cryoanalgesia device used to deliver a precise, controlled application of cold temperature only to targeted nerves, which we sell directly to end users. The iovera° system is highly complementary to EXPAREL as a non-opioid therapy that alleviates pain by disrupting pain signals being transmitted to the brain from the site of injury or surgery.

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

Novel Coronavirus (COVID-19) Pandemic

Our net product sales were negatively impacted by the COVID-19 pandemic in 2020 and have continued to be thus far in 2021, due to the significant postponement or suspension in the scheduling of elective surgical procedures resulting from public health guidance and government directives. Elective surgery restrictions began to lift on a state-by-state basis in April 2020; however while many restrictions have since eased and COVID-19 vaccines become more widely available and administered to the general public, we still do not know how long it will take the elective surgery market to normalize, or if restrictions on elective procedures will recur. Our manufacturing sites are operational and have implemented new safety protocols and guidelines as recommended by federal, state and local governments. To date, there have been no material impacts to our supply chain. With the reopening of many states, the ability of our sales representatives to renew their in-person engagement efforts, in conjunction with remote efforts, has occurred across all sites of care, with more focus on physician offices and ambulatory surgery centers. Our offices have re-opened with strict safety and hygiene guidelines implemented, and we continue to support remote working as appropriate.

The situation remains dynamic and is subject to rapid and possibly material changes. It is not clear what the potential effects may be to our business going forward, including the impact on our revenues, results of operations or financial condition, particularly if these pandemic conditions persist or exacerbate over an extended period of time, including if states return to placing restrictions on elective surgical procedures or if patients are still reluctant to schedule an elective surgical procedure regardless of whether or not they have received a COVID-19 vaccine. Additional negative impacts may also arise from the COVID-19 pandemic 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, including the availability and efficacy of COVID-19 vaccines and the willingness of the general public to get vaccinated.

We will continue to actively monitor the situation and implement measures recommended by federal, state or local authorities, or that we determine are in the best interests of our patients, employees, partners, suppliers, shareholders and stakeholders. For a description of risks facing the Company that relate to the COVID-19 pandemic or any other future pandemic, epidemic or outbreak of contagious disease, see our Annual Report on Form 10-K for the year ended December 31, 2020.

Recent Highlights

•In December 2020, we made a €1.0 million initial investment in GeneQuine Biotherapeutics GmbH, or GeneQuine, a privately held biopharmaceutical company headquartered in Hamburg, Germany. In January 2021, we made an additional €1.0 million investment in the form of a convertible note. We will make an additional €4.0 million investment if and when GeneQuine achieves certain prespecified near-term milestones related to its lead gene therapy product candidate, GQ-303. Up to €2.5 million of our total investment will be in the form of a convertible note, which includes the investment made in January 2021.

• In March 2021, the FDA approved the submission of our sNDA seeking expansion of the EXPAREL label to include use in patients 6 years of age and older for single-dose infiltration to produce postsurgical local analgesia. With this approval, EXPAREL is the first and only FDA approved long-acting local analgesic for the pediatric population as young as age six.

• In April 2021, we made a cash investment of $3.0 million in a convertible note agreement with Spine BioPharma, LLC, or Spine BioPharma, a preclinical stage biopharmaceutical company developing a non-opioid solution to relieve pain and restore functionality. The investment will support the advancement of Spine BioPharma’s lead candidate, Remedisc™, a first-in-class therapeutic for the treatment of degenerative disc disease. We will make an additional $7.0 million investment if and when Spine BioPharma achieves certain prespecified milestones.

EXPAREL

In the U.S., EXPAREL is currently indicated in patients 6 years of age and older for single-dose infiltration to produce postsurgical local analgesia, and in adults as an interscalene brachial plexus nerve block to produce postsurgical regional analgesia. Safety and efficacy have not been established in other nerve blocks. In the E.U., EXPAREL is indicated 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.

Label Expansion

Pediatrics

In March 2021, the FDA approved our sNDA to expand the EXPAREL label to include use in patients 6 years of age and older for single-dose infiltration to produce postsurgical local analgesia. With this approval, EXPAREL is the first and only FDA approved long-acting local analgesic for the pediatric population as young as age six. The sNDA was based on the positive data from the Phase 3 PLAY study of EXPAREL infiltration in pediatric patients undergoing spinal or cardiac surgeries. Overall findings were consistent with the pharmacokinetic and safety profiles for adult patients with no safety concerns identified at a dose of 4 mg/kg. The PLAY study enrolled 98 patients to evaluate safety and the pharmacokinetics of EXPAREL for two patient groups: patients aged 12 to less than 17 years and patients aged 6 to less than 12 years. Per FDA guidance, the primary objectives of the PLAY study were to evaluate the pharmacokinetics and safety of EXPAREL.

We are also working with the FDA to finalize a regulatory pathway to expand the EXPAREL label for patients less than six years of age, as well as the administration of EXPAREL as a nerve block in the pediatric setting, and are working with both the FDA and the European Medicines Agency, or EMA, to harmonize our pediatric clinical studies as much as possible between the two regions.

Nerve Block in Lower Extremity Surgery

We recently completed enrollment in a Phase 3 study for nerve block in lower extremity surgeries (known as “STRIDE”) that compared an EXPAREL nerve block in lower extremity surgeries to a bupivacaine lower extremity nerve block in patients undergoing foot and ankle surgeries. We believe positive results from this study will support an sNDA submission seeking label expansion to include lower extremity nerve blocks. A filing strategy was agreed to with the FDA, and we intend to file a variation with the EMA. We believe the addition of this indication is significant as anesthesia-driven regional approaches using nerve and field blocks continue to expand as institutional protocols.

Global Expansion

We have defined a global expansion strategy for EXPAREL that we believe provides us with the opportunity to increase our revenue and leverage our fixed cost infrastructure. In the E.U., EXPAREL was granted marketing authorization in November 2020. We are planning to launch EXPAREL together with iovera° in targeted European countries during the third quarter of 2021. We do not intend to pursue a partnership to commercialize EXPAREL in Europe.

The European Commission decision is applicable to all 27 E.U. member states plus the United Kingdom, Iceland, Norway and Liechtenstein. Despite the United Kingdom’s withdrawal from the E.U. (“Brexit”), this approval is recognized by the United Kingdom Medicines and Healthcare products Regulatory Agency (MHRA).

In Canada, Health Canada has validated our New Drug Submission and we remain in labeling discussions.

In China, we had an agreement with Nuance Biotech Co. Ltd., or Nuance, a China-based specialty pharmaceutical company, for the development and commercialization of EXPAREL. In April 2021, we and Nuance agreed to a mutual termination of the agreement due to the lack of a viable regulatory pathway that adequately safeguards our intellectual property against the risk of a generic product.

Pacira BioSciences, Inc. | Q1 2021 Form 10-Q | Page 27

iovera°

The iovera° System

The iovera° system is highly complementary to EXPAREL as a novel cold technology that administers a non-pharmacological nerve block to safely and immediately deliver long-term, non-opioid pain control. The iovera° handheld device is 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. It is also indicated for the relief of pain and symptoms associated with arthritis of the knee for up to 90 days.

Our commercial strategy for iovera° focuses on two broad market segments. First, iovera° and EXPAREL for opioid-sparing pain management for the total knee arthroplasty, or TKA, patient, with iovera° being administered before surgery and EXPAREL administered during surgery. We are enrolling patients into our PREPARE study that will evaluate iovera° and EXPAREL for TKA. As many as 30% of presurgical patients with end-stage knee osteoarthritis use prescription opioids. With iovera°, our goal is to provide patients with several months of non-opioid pain control to allow them to prepare for surgery with an appropriate regimen. We also believe that EXPAREL plus iovera° for postsurgical pain control could support rapid functional recovery.

The second target market is iovera° for osteoarthritis patients who have failed conservative treatments, such as non-steroidal anti-inflammatory drugs or viscosupplementation, and are seeking drug-free, opioid-free, surgery-free pain management for several months. We are targeting patients who are seeking an active lifestyle, as well as patients who desire to delay surgery for personal or medical reasons.

Osteoarthritis of the Knee

There is a growing body of clinical data demonstrating success with the iovera° treatment for osteoarthritis of the knee. There are 14 million individuals in the U.S. who have symptomatic knee osteoarthritis, and nearly two million are under the age of 45. Surgical intervention is typically a last resort for patients suffering from osteoarthritis of the knee. In one study, the majority of the patients suffering from osteoarthritis of the knee experienced pain relief beyond 150 days after being treated with iovera°.

Preliminary findings demonstrated reductions in opioids, including:

•The daily morphine equivalent was significantly lower at 72 hours (p<0.05), 6 weeks (p<0.05) and 12 weeks (p<0.05), with an overall 35 percent reduction in daily morphine equivalents across the 12-week postoperative period in the iovera° treatment group.

•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 TKA in the control group was three times the number of patients taking opioids in the cryoanalgesia group (14% vs. 44%, p<0.01).

•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 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;

•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 ultrasound guidance or an anatomical landmark.

We believe the combination of iovera° and EXPAREL will become the preferred procedural solution that will empower patients and their healthcare providers to take control of the patients’ osteoarthritis journey, while minimizing the need for

Pacira BioSciences, Inc. | Q1 2021 Form 10-Q | Page 28

opioids. We will be investing in key clinical studies to demonstrate the synergy of iovera° and EXPAREL to manage pain while reducing or eliminating opioids.

Product Portfolio and Product Candidate Pipeline

Our current product portfolio and product candidate pipeline, along with anticipated milestones over the next 12 to 18 months, are summarized in the table below:

Pacira Innovation and Training Center of Tampa

In October 2020, we announced the grand opening of the Pacira Innovation and Training center of Tampa (the “PITT”). We designed this facility to help advance clinician understanding of the latest local, regional and field block approaches for managing pain. The PITT provides an unparalleled training environment for healthcare providers working to reduce or eliminate patient exposure to opioids. The PITT supports a full range of educational events to advance clinician understanding of the latest local, regional, and field block approaches for managing pain and reducing or eliminating exposure to opioids.

The PITT consists of approximately 10,000 square-feet of fully adaptable space and is equipped with state-of-the-art technology and audio/visual capabilities and features several distinct training spaces including a simulation lab equipped with seven ultrasound scanning stations; a lecture hall featuring a 4½-foot-tall by 24-foot-wide liquid crystal display video wall to

support live, virtual and even global presentations; and a green-screen broadcast studio designed to livestream content with single or multiple hosts.

In addition to our EXPAREL programs, we are hosting ongoing workshops to train new users on best practice techniques for iovera° administration at the PITT. Led by healthcare professionals, these labs include didactic lectures and hands-on trainings including live model nerve scanning and identification using ultrasound and peripheral nerve stimulation.

The PITT also serves as a venue for national anesthesia provider organizations to host their own workshops and training sessions.

Results of Operations

Comparison of the Three Months Ended March 31, 2021 and 2020

Revenues

Net product sales consist of sales of EXPAREL in the U.S., our bupivacaine liposome injectable suspension to Aratana Therapeutics, Inc., or Aratana, for veterinary use in the U.S. and sales of iovera° in the U.S. Licensing, milestone and royalty revenues are from our collaborative licensing agreements.

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

	Three Months Ended March 31,				% Increase / (Decrease)
	2021		2020
Net product sales:
EXPAREL	$	114,678	$	101,269	13%
Bupivacaine liposome injectable suspension	792		1,206		(34)%
Total EXPAREL / bupivacaine liposome injectable suspension net product sales	115,470		102,475		13%
iovera°	3,268		2,270		44%
Total net product sales	118,738		104,745		13%
Royalty revenue	289		939		(69)%
Total revenues	$	119,027	$	105,684	13%

EXPAREL revenue grew 13% in the three months ended March 31, 2021 versus 2020, primarily due to an increase in sales volume of 12% and a 4% increase in gross selling price per unit, partially offset by the sales mix of EXPAREL vial sizes. The demand for EXPAREL has generally continued to increase as a result of ambulatory surgery centers and anesthesiologists broadening the use of long-acting EXPAREL regional approaches as a foundation of multimodal opioid-minimization strategies that enable shifting inpatient procedures to 23-hour sites of care. EXPAREL utilization remained above the overall sharp decline in elective surgical procedures relative to pre-pandemic baseline levels, due to increased use in the outpatient setting. EXPAREL utilization in emergency procedures also continues to grow.

Bupivacaine liposome injectable suspension revenue and related royalties decreased 34% and 69%, respectively, in the three months ended March 31, 2021 versus 2020, as a result of the timing of orders placed by Aratana for veterinary use.

Net product sales of iovera° increased 44% in the three months ended March 31, 2021 versus 2020, primarily due to an increased iovera° sales force and the impact that the COVID-19 pandemic had on the first quarter of 2020. Thus far, we have seen the greatest iovera° demand as pain relief for patients in advance of TKA procedures and in chronic pain management, particularly for people with mild to severe osteoarthritis of the knee.

Any renewed government suspension of, or reluctance of patients to have, elective surgeries would impact our future sales of EXPAREL and iovera° during the ongoing COVID-19 pandemic.

The following tables provide a summary of activity with respect to our sales related allowances and accruals related to EXPAREL for the three months ended March 31, 2021 and 2020 (in thousands):

Balance at March 31, 2020	$	609	$	761	$	984	$	1,508	$	3,862

Total reductions to gross product sales from sales-related allowances and accruals were $7.1 million and $6.4 million, or 5.7% and 5.8% of gross product sales, for the three months ended March 31, 2021 and 2020, respectively. The overall decrease in sales-related allowances and accruals as a percentage of gross product sales was directly related to a slight decrease in discounting.

Cost of Goods Sold

Cost of goods sold primarily relates to the costs to produce, package and deliver our products to customers. These expenses include labor, raw materials, manufacturing overhead and occupancy costs, depreciation of facilities, royalty payments, quality control and engineering.

The following table provides information regarding our cost of goods sold and gross margin during the periods indicated, including percent changes (dollar amounts in thousands):

	Three Months Ended March 31,						% Increase / (Decrease)
	2021			2020
Cost of goods sold	$	31,349		$	29,732		5%
Gross margin	74		%	72		%

Gross margin increased two percentage points in the three months ended March 31, 2021 versus 2020. The most significant changes were one percentage point due to increased sales of lower cost quantities manufactured at our custom manufacturing suite in Swindon, England, and one percentage point due to a price increase.

Research and Development Expenses

Research and development expenses primarily consist of costs related to clinical trials and related outside services, product development and other research and development costs, including Phase 4 trials that we are conducting to generate new data for EXPAREL and iovera° and stock-based compensation expense. Clinical and preclinical development expenses include costs for clinical personnel, clinical trials performed by third-parties, toxicology studies, materials and supplies, database management and other third-party fees. Product development and manufacturing capacity expansion expenses include development costs for our products, which include personnel, equipment, materials and contractor costs for process development and product candidates, development costs related to significant scale-ups of our manufacturing capacity and facility costs for our research space. Regulatory and other expenses include regulatory activities related to unapproved products and indications, medical information expenses and related personnel. Stock-based compensation expense relates to the costs of stock option grants, awards of restricted stock units, or RSUs, and our employee stock purchase plan, or ESPP.

The following table provides a breakout of our research and development expenses during the periods indicated, including percent changes (dollar amounts in thousands):

Pacira BioSciences, Inc. | Q1 2021 Form 10-Q | Page 31

	Three Months Ended March 31,						% Increase / (Decrease)
	2021			2020
Clinical and preclinical development	$	8,020		$	6,359		26%
Product development and manufacturing capacity expansion	4,702			6,605			(29)%
Regulatory and other	2,051			1,669			23%
Stock-based compensation	1,106			1,186			(7)%
Total research and development expense	$	15,879		$	15,819		0%
% of total revenues	13		%	15		%

Total research and development expense remained flat in the three months ended March 31, 2021 versus 2020.

Clinical and preclinical development expense increased 26% in the three months ended March 31, 2021 versus 2020 due to ongoing enrollment in our iovera° and EXPAREL TKA (“PREPARE”) trial as well as continued and completed enrollment in our lower extremity nerve block (“STRIDE”) clinical trial. These increases were partially offset by the completion of our Phase 3 pediatric (“PLAY”) clinical trial, our Phase 4 C-Section (“CHOICE”) trial, as well as the completion of our clinical trial for pectoral field block in breast augmentation. In addition, we made the strategic decision to conclude enrollment in the spine (“FUSION”) study early due to protocol feasibility given the rapid evolution of medical practice for spinal procedures. The data from approximately 65 FUSION study subjects will be analyzed with the intent to create either a future study or registry for this patient population.

Product development and manufacturing capacity expansion expense decreased 29% in the three months ended March 31, 2021 versus 2020. These decreases are mainly due to our progress in constructing the significant scale-up of our manufacturing capacity at the Thermo Fisher Scientific Pharma Services, or Thermo Fisher, site in Swindon, England as the project advances from the development phase to the registration phase.

Regulatory and other expense increased 23% in the three months ended March 31, 2021 versus 2020 due to regulatory activities in support of our pediatric infiltration sNDA submission and activities related to an iovera° clinical data registry.

Stock-based compensation decreased by 7% in the three months ended March 31, 2021 versus 2020, primarily due to fewer equity awards outstanding for research and development personnel, partially offset by an increase in the average cost of equity grants.

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, commission payments to our marketing partners for the promotion and sale of EXPAREL and iovera°, expenses related to communicating the health outcome benefits of EXPAREL 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.

The following table provides information regarding our selling, general and administrative expenses during the periods indicated, including percent changes (dollar amounts in thousands):

	Three Months Ended March 31,						% Increase / (Decrease)
	2021			2020
Sales and marketing	$	27,102		$	27,912		(3)%
General and administrative	13,868			10,426			33%
Stock-based compensation	7,552			6,442			17%
Total selling, general and administrative expense	$	48,522		$	44,780		8%
% of total revenues	41		%	42		%

Pacira BioSciences, Inc. | Q1 2021 Form 10-Q | Page 32

Total selling, general and administrative expenses increased 8% in the three months ended March 31, 2021 versus 2020.

Sales and marketing expenses decreased 3% in the three months ended March 31, 2021 versus 2020. The 3% decrease was driven by the termination of our co-promotion agreement with DePuy Synthes Sales, Inc. and was partially offset by higher compensation due to an expanded sales force and pediatric launch expenses in anticipation of the March 2021 FDA approval of the sNDA for EXPAREL in infiltration for pediatric patients aged 6 and up. We are continuing our marketing investment in EXPAREL, which includes educational initiatives and programs related to the impact of opioids and postsurgical pain management and our national advocacy campaign designed to educate patients about non-opioid treatment options. Additionally, we have continued our investment in clinician training of the use of EXPAREL and iovera° at our PITT training facility in Tampa, Florida. We have also continued investing in marketing initiatives and customer outreach for iovera°.

General and administrative expenses increased 33% in the three months ended March 31, 2021 versus 2020 primarily due to an insurance recovery of $2.1 million received in early 2020 for legal expenditures related to a since-resolved Department of Justice inquiry and an increase in legal expenditures in support of other matters.

Stock-based compensation increased 17% in the three months ended March 31, 2021 versus 2020, primarily due to an increase in the average cost of equity grants, partially offset by fewer awards outstanding.

Amortization of Acquired Intangible Assets

The following table provides a summary of the amortization of acquired intangible assets during the periods indicated, including percent changes (dollar amounts in thousands):

	Three Months Ended March 31,				% Increase / (Decrease)
	2021		2020
Amortization of acquired intangible assets	$	1,967	$	1,967	—%

As part of the April 2019 acquisition of MyoScience (the “MyoScience Acquisition”), we acquired intangible assets consisting of developed technology and customer relationships, with estimated useful lives of 14 and 10 years, respectively. For more information, see Note 7, Goodwill and Intangible Assets, to our condensed consolidated financial statements included herein.

Acquisition-Related Gains, Product Discontinuation and Other

The following table provides a summary of the costs related to the MyoScience Acquisition, our DepoCyt(e) discontinuation activities and termination costs for our agreement with Nuance during the periods indicated, including percent changes (dollar amounts in thousands):

	Three Months Ended March 31,				% Increase / (Decrease)
	2021		2020
Acquisition-related gains	$	(1,127)	$	(3,739)	(70)%
Product discontinuation	—		31		(100)%
Other	3,000		—		N/A
Total acquisition-related gains, product discontinuation and other	$	1,873	$	(3,708)	N/A

As part of the MyoScience Acquisition, we recognized gains in the amount of $1.1 million and $3.7 million in the three months ended March 31, 2021 and 2020, respectively, primarily related to changes in the fair value of contingent consideration. See Note 9, Financial Instruments, to our condensed consolidated financial statements included herein, for information regarding the methods and key assumptions used in the fair value measurements of contingent consideration.

In June 2018, we entered into an agreement with Nuance, to advance the development and commercialization of EXPAREL in China. In April 2021, we agreed to a mutual termination of the agreement due to the lack of a viable regulatory pathway that adequately safeguards our intellectual property against the risk of a generic product. Estimated dissolution costs of $3.0 million have been included in other operating expenses in the condensed consolidated statements of operations for the three months ended March 31, 2021.

Other Income (Expense)

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

	Three Months Ended March 31,				% Increase / (Decrease)
	2021		2020
Interest income	$	415	$	1,589	(74)%
Interest expense	(6,971)		(6,022)		16%
Other, net	(157)		(4,104)		(96)%
Total other expense, net	$	(6,713)	$	(8,537)	(21)%

Total other expense, net decreased by 21% in the three months ended March 31, 2021 versus 2020, primarily due to lower unrealized losses on our equity investment in TELA Bio, Inc., which were $0.1 million during the three months ended March 31, 2021 and $4.0 million during the three months ended March 31, 2020. Further, our interest income decreased in the three months ended March 31, 2021 versus 2020 due to lower short-term interest rates. The increase in interest expense in the current period was primarily due to an increase in outstanding debt resulting from the issuance of $402.5 million aggregate principal of our 0.750% convertible senior notes due 2025, or 2025 Notes, in July 2020.

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 March 31,						% Increase / (Decrease)
	2021			2020
Income tax expense	$	2,355		$	398		100%+
Effective tax rate	19		%	5		%

For the three months ended March 31, 2021 and 2020, we recorded an income tax expense of $2.4 million and $0.4 million, respectively. The increased income tax expense was driven by the release of a full valuation allowance against domestic net deferred tax assets during the year ended December 31, 2020. The income tax expense for the three months ended March 31, 2021 represents the estimated annual effective tax rate applied to the year-to-date domestic operating results adjusted for certain discrete tax benefits related to equity compensation. The income tax expense for the three months ended March 31, 2020 consisted primarily of state income taxes in jurisdictions where the availability of carryforward losses were either limited or fully utilized.

Liquidity and Capital Resources

Since our inception in December 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 iovera° as part of the MyoScience Acquisition in April 2019. We are highly dependent on the commercial success of EXPAREL, which we launched in April 2012. We have financed our operations primarily with the proceeds from the sale of convertible senior notes, common stock, product sales and collaborative licensing and milestone revenue. As of March 31, 2021, we had an accumulated deficit of $243.5 million, cash and cash equivalents, short-term and long-term investments of $625.0 million and working capital of $488.2 million. We currently expect that our cash, short-term and long-term investments on hand will be adequate to cover any potential short-term liquidity needs, and that we would be able to access other sources of financing should the need arise.

On March 27, 2020, the Coronavirus Aid, Relief and Economic Security (CARES) Act was signed into law in response to the COVID-19 pandemic. The CARES Act, among other things, allowed for certain measures to increase liquidity for businesses such as the deferral of employer payroll taxes, a tax credit for retaining employees and other provisions. We benefited from the provision to defer the payment of certain employer payroll taxes in the amount of $2.8 million for the year ended December 31, 2020. One-half of these deferrals are due at each of December 31, 2021 and December 31, 2022.

Summary of Cash Flows

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

	Three Months Ended March 31,
Condensed Consolidated Statements of Cash Flows Data:	2021		2020
Net cash provided by (used in):
Operating activities	$	12,081	$	6,208
Investing activities	(55,664)		(28,566)
Financing activities	10,325		(1,281)
Net decrease in cash and cash equivalents	$	(33,258)	$	(23,639)

Operating Activities

During the three months ended March 31, 2021, net cash provided by operating activities was $12.1 million, compared to $6.2 million during the three months ended March 31, 2020. The increase of $5.9 million was primarily attributable to an increase in gross margin on a 13% increase in EXPAREL net product sales, partially offset by increased general and administrative expenses, largely associated with legal expenses.

Investing Activities

During the three months ended March 31, 2021, net cash used in investing activities was $55.7 million, which reflected $41.4 million of short-term and long-term investment purchases (net of maturities) and purchases of fixed assets of $13.1 million. Major fixed asset purchases included equipment for a new EXPAREL capacity expansion at our Science Center Campus in San Diego, California, and continuing expenditures for our expanding EXPAREL manufacturing capacity in Swindon, England. In addition, we purchased a $1.2 million convertible note from GeneQuine.

During the three months ended March 31, 2020, net cash used in investing activities was $28.6 million, which reflected $21.8 million of short-term and long-term investment purchases (net of maturities) and purchases of fixed assets of $6.7 million. Major fixed asset purchases included equipment for a new EXPAREL capacity expansion project at our Science Center Campus.

Financing Activities

During the three months ended March 31, 2021, net cash provided by financing activities was $10.3 million, which consisted entirely of proceeds from the exercise of stock options.

During the three months ended March 31, 2020, net cash used in financing activities was $1.3 million, which consisted of $4.7 million of contingent consideration payments made to MyoScience securityholders, partially offset by proceeds from the exercise of stock options of $3.5 million.

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, or 2025 Indenture, with respect to the 2025 Notes. The 2025 Notes accrue interest at a fixed rate of 0.750% per annum, payable in arrears on February 1 and August 1 of each year. The 2025 Notes mature on August 1, 2025. At March 31, 2021, the outstanding principal on the 2025 Notes was $402.5 million.

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. For both the principal and excess conversion value, holders may receive cash, shares of our common stock or a combination of cash and shares of our common stock, at our 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 approximately $71.78 per share of our common stock. The conversion rate will be subject to adjustment in some events but will not be adjusted for any accrued and unpaid interest.

Pacira BioSciences, Inc. | Q1 2021 Form 10-Q | Page 35

Prior to the close of business on the business day immediately preceding February 3, 2025, holders may convert the 2025 Notes under certain circumstances, including if during any given calendar quarter, our stock price closes at or above 130% of the conversion price then applicable during a period of at least 20 out of the last 30 consecutive trading days of the previous quarter.

While the 2025 Notes are currently classified on our consolidated balance sheet at March 31, 2021 as long-term debt, the future convertibility and resulting balance sheet classification of this liability will be monitored at each quarterly reporting date and will be analyzed dependent upon market prices of our common stock during the prescribed measurement periods. In the event that the holders of the 2025 Notes have the right 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.

On or after August 1, 2023, we may redeem for cash, shares of our common stock or a combination of cash and shares of our common stock, at our option, all or part of the 2025 Notes if the last reported sale price (as defined in the 2025 Indenture) of our common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading-day period ending within five trading days prior to the date on which we provide notice of redemption. This condition was not met during the quarter ended March 31, 2021.

See Note 8, Debt, to our condensed consolidated financial statements included herein for further discussion of the 2025 Notes.

2022 Convertible Senior Notes

In March 2017, we completed a private placement of $345.0 million in aggregate principal amount of our 2.375% convertible senior notes due 2022, or 2022 Notes, and entered into an indenture, or 2022 Indenture, with respect to the 2022 Notes. The 2022 Notes accrue interest at a fixed rate of 2.375% per annum, payable semiannually in arrears on April 1 and October 1 of each year. The 2022 Notes mature on April 1, 2022. At March 31, 2021, the outstanding principal on the 2022 Notes was $160.0 million. In July 2020, we used part of the net proceeds from the issuance of the 2025 Notes discussed above to repurchase $185.0 million aggregate principal of the 2022 Notes in privately-negotiated transactions for an aggregate of approximately $211.1 million in cash, including accrued interest.

On or after October 1, 2021, until the close of business on the second scheduled trading day immediately preceding April 1, 2022, holders may convert their 2022 Notes at any time. Upon conversion, holders will receive the principal amount of their 2022 Notes and any excess conversion value. For both the principal and excess conversion value, holders may receive cash, shares of our common stock or a combination of cash and shares of our common stock, at our option. The initial conversion rate for the 2022 Notes is 14.9491 shares of common stock per $1,000 principal amount, which is equivalent to an initial conversion price of approximately $66.89 per share of our common stock. The conversion rate will be subject to adjustment in some events but will not be adjusted for any accrued and unpaid interest.

Prior to the close of business on the business day immediately preceding October 1, 2021, holders may convert the 2022 Notes under certain circumstances, including if during any given calendar quarter, our stock price closes at or above 130% of the conversion price then applicable during a period of at least 20 out of the last 30 consecutive trading days of the previous quarter.

The holders of the 2022 Notes have the right to convert the 2022 Notes at any time on or after October 1, 2021, until the close of business on the second scheduled trading day immediately preceding April 1, 2022. Therefore, the 2022 Notes are considered a current obligation to the Company. While the 2022 Notes are currently classified on our consolidated balance sheet at March 31, 2021 as short-term debt, the future convertibility 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.

As of April 1, 2020, we may redeem for cash, shares of our common stock or a combination of cash and shares of our common stock, at our option, all or part of the 2022 Notes if the last reported sale price (as defined in the 2022 Indenture) of our common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading-day period ending within five trading days prior to the date on which we provide notice of redemption. This condition was not met during the quarter ended March 31, 2021.

See Note 8, Debt, to our condensed consolidated financial statements included herein for further discussion of the 2022 Notes.

Future Capital Requirements

We believe that our existing cash and cash equivalents, short-term and long-term investments and cash received from product sales will be sufficient to enable us to fund our operating expenses, capital expenditure requirements, payment of the principal on any conversions of our 2022 Notes and 2025 Notes, and to service our indebtedness 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 following:

•the impact of the COVID-19 pandemic, including the amounts and delays of suspended elective surgical procedures, clinical trials and general economic conditions;

•the costs and our ability to successfully continue to expand the commercialization of EXPAREL and iovera°, including outside of the U.S.;

•the cost and timing of expanding our manufacturing facilities for EXPAREL and other product candidates, including the construction of an additional manufacturing suite at Thermo Fisher’s facility in Swindon, England and an EXPAREL capacity expansion project at our Science Center Campus in San Diego, California;

•the cost and timing of potential remaining milestone payments to MyoScience security holders, which could be up to an aggregate of $58.0 million if certain regulatory and commercial milestones are met, which includes one milestone payment of $10.0 million which is payable in the second quarter of 2021;

•the cost and timing of potential milestone payments to SkyePharma Holding, Inc., which could be up to an aggregate of $36.0 million if certain milestones pertaining to net sales of DepoBupivacaine products, including EXPAREL, are met, or upon the first commercial sale in the United Kingdom, France, Germany, Italy or Spain;

We may require additional debt or equity financing to meet our future operating and capital requirements.

In particular, capital market disruptions or negative economic conditions, especially in light of the COVID-19 pandemic, may hinder our access to capital.

Off-Balance Sheet Arrangements

We do not have any material off-balance sheet arrangements as of March 31, 2021, nor do we have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities.

Critical Accounting Policies and Use of Estimates

See Note 2, Summary of Significant Accounting Policies, to our condensed consolidated financial statements included herein for a discussion of recently issued accounting pronouncements and their impact or future potential impact on our financial results, if determinable. 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 most recent Annual Report on Form 10-K for the year ended December 31, 2020.

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, 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 principal amount 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 March 31, 2021 by approximately $2.7 million.

We have an equity investment in the common stock of TELA Bio, which is publicly traded on the Nasdaq Global Select Market. TELA Bio is measured at fair value on a recurring basis. Changes in the price of its common stock will affect the value of our investment, and we could incur realized or unrealized losses on all or a part of the value of this investment. At March 31, 2021, the value of our investment in TELA Bio was $11.5 million, and a hypothetical 10% decrease in the market price would have caused a decrease in our carrying amount by $1.1 million. See Note 9, Financial Instruments, to our condensed consolidated financial statements included herein for additional information on our equity investments.

In July 2020, we issued $402.5 million in aggregate principal amount of our 2025 Notes, which mature in August 2025. Holders may convert their 2025 Notes prior to maturity under certain circumstances. Upon conversion, holders will receive the principal amount of the 2025 Notes and any excess conversion value in cash, shares of our common stock or a combination of cash and shares, at our option. The fair value of the 2025 Notes is impacted by both the fair value of our common stock and interest rate fluctuations. As of March 31, 2021, the estimated fair value of the 2025 Notes was $1,200 per $1,000 principal amount. See Note 8, Debt, to our condensed consolidated financial statements included herein for further discussion of the 2025 Notes. The 2025 Notes bear interest at a fixed rate. At March 31, 2021, all $402.5 million of principal remains outstanding on the 2025 Notes.

In March 2017, we issued $345.0 million in aggregate principal amount of our 2022 Notes, which mature in April 2022. In July 2020, we used part of the net proceeds from the issuance of the 2025 Notes discussed above to repurchase $185.0 million aggregate principal of the 2022 Notes in privately-negotiated transactions for an aggregate of approximately $211.1 million in cash, including accrued interest. Holders may convert their 2022 Notes prior to maturity under certain circumstances. Upon conversion, holders will receive the principal amount of the 2022 Notes and any excess conversion value in cash, shares of our common stock or a combination of cash and shares, at our option. The fair value of the 2022 Notes is impacted by both the fair value of our common stock and interest rate fluctuations. The 2022 Notes bear interest at a fixed rate. As of March 31, 2021, the estimated fair value of the 2022 Notes was $1,216 per $1,000 principal amount. See Note 8, Debt, to our condensed consolidated financial statements included herein for further discussion of the 2022 Notes. At March 31, 2021, $160.0 million of principal remains outstanding on the 2022 Notes.

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

Additionally, our accounts receivable are primarily concentrated with three 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 Chairman 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

Pacira BioSciences, Inc. | Q1 2021 Form 10-Q | Page 38

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 Chairman and our Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Based on that evaluation, our Chief Executive Officer and Chairman and our Chief Financial Officer concluded that our disclosure controls and procedures were effective as of March 31, 2021.

Changes in Internal Control over Financial Reporting

There has been no change in our internal control over financial reporting that occurred during the quarter ended March 31, 2021 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls

Our management, including the Chief Executive Officer and Chairman 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 error or mistake. 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.
