Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Legal Proceedings From time to time, the Company has been and may again become involved in legal proceedings arising in the ordinary course of its business, including those related to its patents and intellectual property, product liability and government investigations. Except as described below, the Company is not presently a party to any legal proceedings that it believes to be material, and is not aware of any pending or threatened litigation against the Company which it believes could have a material adverse effect on its business, operating results, financial condition or cash flows. The Company is not in a position to assess the likelihood of any potential losses or adverse effect on its financial condition or to estimate the amount or range of potential losses, if any, from the following actions at this time. 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, Inc. and certain other defendants, seeking declaratory judgment with respect to certain terms of the merger agreement for the MyoScience Acquisition (the “MyoScience Merger Agreement”), specifically related to the achievement of certain milestone payments under the MyoScience Merger Agreement. In October 2020, Fortis filed an answer and counterclaim against the Company and Pacira CryoTech seeking to recover certain milestone payments under the MyoScience Merger Agreement. A trial was conducted in September 2023. In January 2025, the Court issued its decision, finding that the disputed milestones were not met and therefore granted judgment to the Company in full. In March 2025, the Company filed a motion to recover attorney fees, and the parties subsequently agreed to settle the amount of expenses owed to the Company, whereby Fortis agreed to pay the Company $5.2 million and waived its rights to appeal the decision. A final judgment and order was entered in April 2025. The $5.2 million payment received was accounted for as a recovery of losses and recorded against selling, general and administrative expense in the six months ended June 30, 2025 within the condensed consolidated statement of operations, consistent to where the previous expenses were recorded. eVenus Pharmaceutical Laboratories Litigations In October 2021, December 2021, April 2023 and May 2024, the Company received Notice Letters advising that eVenus Pharmaceutical Laboratories, Inc., or eVenus, of Princeton, New Jersey, submitted to the United States Food and Drug Administration, or FDA, an Abbreviated New Drug Application, or ANDA with a Paragraph IV certification seeking authorization for the manufacturing and marketing of a generic bupivacaine liposome injectable suspension in the U.S. prior to the expiration of certain of the Company’s U.S. patents. Beginning in November 2021, the Company filed various patent infringement suits against eVenus, its parent company (Jiangsu Hengrui Pharmaceuticals, Co. Ltd., or Jiangsu Hengrui) and Fresenius Kabi USA, LLC, or Fresenius, (together, the “ANDA filers”) in the U.S. District Court for the District of New Jersey asserting infringement of U.S. Patent No. 11,033,495 (the ‘495 patent) (21-cv-19829), U.S. Patent No. 11,179,336 (the ‘336 patent) (22-cv-00718), U.S. Patent No. 11,426,348 (the ‘348 patent) (23-cv-02367), U.S. Patent Nos. 11,819,574 (the ‘574 patent) and 11,819,575 (the ‘575 patent) (24-cv-06294), and U.S. Patent No. 11,925,706 (the ‘706 patent) (24-cv-07680). In December 2024, the Company filed a patent infringement suit against Fresenius and Jiangsu Hengrui in the Northern District of Illinois (24-cv-12416) asserting that the ANDA products will infringe U.S. Patent No. 12,156,940 (the ‘940 patent). Also in December 2024, the ANDA filers filed an action for declaratory judgment of non-infringement and invalidity with respect to the ‘940 patent in the District Court of New Jersey (24-cv-11014). On April 7, 2025, the Company, along with its operating subsidiary, Pacira Pharmaceuticals, Inc., entered into a settlement agreement with the ANDA filers with respect to the litigations noted above. Pursuant to the settlement agreement, the ANDA filers will be enjoined from marketing a generic bupivacaine liposome injectable suspension before the expiration of the patents-in-suit, except as provided for in the settlement agreement, as described below. In settlement of all outstanding claims in the litigations, the Company agreed to provide the ANDA filers with a license to the Company’s patents required to manufacture and sell certain volume-limited amounts of a generic bupivacaine liposome injectable suspension in the U.S. beginning on a confidential date that is sometime in early 2030. While the agreed-upon volume-limited percentages are confidential, they begin at a high single-digit percentage of the total volumes distributed in the U.S. market and increase gradually in each 12-month period following the volume-limited entry date until reaching a percentage in the low thirties in 2033 and increasing modestly in each of the next two 12-month periods before reaching a maximum percentage in the high thirties of the total volumes distributed in the U.S. for the final three years of the agreement. In addition, the Company has agreed to provide the ANDA filers with a license to its patents required to manufacture and sell an unlimited quantity of a generic bupivacaine liposome injectable suspension in the U.S. beginning on a confidential date in 2039. In addition, in recognition of the Company’s expected savings with respect to, among other things, the avoidance of fees, costs, time and resources associated with continuing the litigations, the Company paid the ANDA filers $7.0 million. This legal settlement cost was recorded within contingent consideration (gains) charges, acquisition-related expenses, restructuring and other in the six months ended June 30, 2025 in the Company’s condensed consolidated statement of operations. Argentum Request for Ex Parte Reexamination of ‘495 Patent On October 3, 2024, Argentum Pharmaceuticals LLC, or Argentum, filed a Request for Ex Parte Reexamination of the ‘495 patent. Specifically, Argentum alleged that claims 1, 7 and 8 of the ‘495 patent are obvious and cite to U.S. Patent No. 9,585,838 (the ‘838 patent) and the Physician’s Desk Reference in support of its allegation. In response, the Company submitted rebuttal evidence, certain claim amendments, and new claims. Claim 7 was withdrawn from the reexamination due to the finality of the judgment in the eVenus litigation, and claim 1 was canceled. The USPTO agreed with the Company’s position and issued a Notice of Intent to Issue Ex Parte Reexamination Certificate on June 23, 2025, which indicated the allowability of amended claim 8 and new claims 23-110. Claims 2-6 and 9-22 of the ‘495 Patent were not subject to reexamination. The Company expects the Reexamination Certificate to issue in the second half of the year. Securities Class Action On January 13, 2025, Leandro Alvarez filed a putative class action on behalf of Company shareholders between August 2, 2023 and August 8, 2024 against the Company and certain of its officers, in the District Court of New Jersey (25-cv-322). The complaint alleges that the Company made materially false and misleading statements and/or concealed material adverse facts concerning EXPAREL patents. The case is in the pleadings stage and the Company is unable to predict the outcome of this litigation at this time. Shareholder Derivative Action On June 16, 2025, a Shareholder Derivative suit, Young v. Lee, et al, was filed in the District of New Jersey (25-cv-11841). The complaint alleges that certain officers and members of the Company’s board of directors breached their fiduciary duties by making materially false and misleading statements and/or concealed material adverse facts concerning EXPAREL patents. The Company has not yet been served, and the Company is unable to predict the outcome of this litigation at this time. Research Development Foundation Pursuant to an agreement with the Research Development Foundation, or RDF, the Company was required to pay RDF a low single-digit royalty on the collection of revenues from certain products for as long as certain patents assigned to the Company under the agreement remain valid. RDF has the right to terminate the agreement for an uncured material breach by the Company, in connection with its bankruptcy or insolvency or if it directly or indirectly opposes or disputes the validity of the assigned patent rights. The Company’s ‘495 patent was issued on June 15, 2021. Thereafter, RDF asserted that the issuance of that patent extends the Company’s royalty obligations under the agreement until 2041. The Company believes that the royalty period under the agreement ended on December 24, 2021 with the expiration of the ‘838 patent. Because of the disagreement over the interpretation of the agreement, in December 2021, the Company filed a declaratory judgment lawsuit in the U.S. District Court for the District of Nevada (21-cv-02241). The lawsuit sought a declaration from the court that the Company owed no royalties to RDF with respect to its EXPAREL product after December 24, 2021. In August 2023, the U.S. District Court, District of Nevada granted the Company’s motion for partial summary judgment in respect to the Company’s claim for a declaration that it no longer owes royalties for EXPAREL made under its 45-liter batch manufacturing process as of December 24, 2021. A trial as to whether royalties were owed on EXPAREL made under the Company’s enhanced, larger-scale manufacturing process was conducted in September 2024. In April 2025, the Court issued judgment in favor of the Company. As a result, the low single-digit royalty that the Company had been paying RDF is eliminated, and the Company sought repayment of up to $23.1 million, plus interest, from RDF, representing the royalties that the Company paid to RDF under protest on the collection of revenues of EXPAREL that occurred after December 24, 2021. In June 2025, the U.S. District Court for the District of Nevada issued judgment in favor of the company declaring that RDF is required to repay Pacira $23.1 million in royalties on EXPAREL sales that were previously paid under protest. The Nevada Court also awarded Pacira an additional interest payment of $5.2 million in statutory interest on the royalties paid under protest. In July 2025, the Company received the $28.3 million cash payment and will recognize the amount in its condensed consolidated financial statements in the third quarter of 2025 when the cash related to the judgment was received by the Company. Other Commitments and Contingencies Johnson & Johnson MedTech In July 2025, the Company entered into a co-promotion agreement (the “J&J Agreement”), with Johnson & Johnson MedTech, or J&J MedTech, to market and promote the use of ZILRETTA for OA knee pain in the U.S. J&J MedTech’s specialized early intervention sales force will extend the reach of ZILRETTA beyond orthopedic practices, into multiple new physician specialties, including sports medicine, osteopathy, pain management and rheumatology. Under the J&J Agreement, J&J MedTech is the exclusive third-party co-promoter for ZILRETTA in the U.S. The initial term of the J&J Agreement extends through 2031 with an option to extend under mutual agreement. The Company will continue to recognize all revenue from sales of ZILRETTA. As compensation for its promotional efforts, for the first 12 months of the J&J Agreement the Company will pay J&J MedTech a minimum monthly commission. For the remaining term of the agreement, Pacira will pay a tier-based commission with higher commission percentages earned at higher annual ZILRETTA sales levels. J&J MedTech will receive a tiered commission ranging from low single digits to double digits. The Company and J&J MedTech have mutual termination rights under the J&J Agreement, subject to certain terms, conditions and advance notice requirements, provided that the Company or J&J MedTech generally may not terminate the J&J Agreement, without cause, within one year of the effective date of the J&J Agreement. The Company also has additional unilateral termination rights under certain circumstances. The J&J Agreement contains customary representations, warranties, covenants and confidentiality provisions, as well as mutual indemnification obligations. J&J MedTech is also subject to certain obligations and restrictions, including required compliance with certain laws and regulations and the Company’s policies, in connection with fulfilling their obligations under the J&J Agreement. Pediatric Trial Commitments The FDA, as a condition of EXPAREL approval, has required the Company to study EXPAREL for infiltration and as a brachial plexus block in pediatric patients. The Company was granted deferrals for the required pediatric trials until after the indications were approved in adults. Similarly, in Europe, the Company agreed with the European Medicines Agency, or EMA, on a Pediatric Investigation Plan as a prerequisite for submitting a Marketing Authorization Application (MAA) in the E.U. Despite the U.K.’s withdrawal from the E.U., the agreed pediatric plan is applicable in the U.K. The Company has received notification from both the FDA and EMA that its pediatric studies requirement had been waived for the indications of brachial plexus interscalene nerve block, lower extremity nerve block, sciatic nerve block in the popliteal fossa and adductor canal block indications to produce postsurgical regional analgesia in pediatric patients. The Company is still working with the FDA, EMA and Medicines and Healthcare Regulatory Agency (MHRA) to finalize the regulatory pathways for its remaining pediatric commitments. The Company has successfully completed Part 1 of a pediatric study in children aged two to less than six years of age. As a result, the Company is implementing Part 2 of the pediatric study in children aged six months to less than two years of age using the same dosage that was utilized in Part 1. Contingent Milestone Payments Refer to Note 10, Financial Instruments, for information on potential contingent milestone payments related to the Flexion Acquisition. PCRX-201 PCRX-201 (enekinragene inzadenovec) is a novel, locally administered gene therapy vector platform product candidate that boosts cellular production of the anti-inflammatory protein interleukin-1 receptor antagonist (IL-1Ra) for treating OA pain in the knee and was added to the Company’s portfolio as part of the Flexion Acquisition in November 2021. In 2017, in an agreement between The Baylor College of Medicine, or BCM, and GQ Bio, the Company (through the Flexion Acquisition) became the direct licensee of certain underlying BCM patents and other proprietary rights related to PCRX-201. The license agreement grants the Company an exclusive, royalty-bearing, world-wide right and license under its patent and other proprietary rights directly related to PCRX-201. The license agreement with BCM includes a low single-digit royalty on net product sales of PCRX-201. Milestone payments range from $0.1 million up to $0.6 million based on the completion of a Phase 1 FDA trial up to a Phase 3 clinical trial. In February 2024, the FDA granted a Regenerative Medicine Advanced Therapy (RMAT) designation to PCRX-201 for the treatment of OA pain of the knee. Purchase Obligations In July 2025, the Company entered into a non-cancelable contractual commitment of approximately $4.0 million and $5.5 million in 2025 and 2026, respectively.
