BRISBANE, Calif., Oct. 05, 2026 — Pacira BioSciences, Inc. (NASDAQ: PCRX), the industry leader in its commitment to deliver innovative, non-opioid pain therapies to transform the lives of patients, today announced a strategic partnership with Molteni Farmaceutici to expand access to opioid-sparing postsurgical pain management across European markets. Through this partnership, Molteni Farmaceutici will receive exclusive rights to distribute and commercialize EXPAREL® (bupivacaine liposome injectable suspension), Pacira’s long-acting, local analgesic for postsurgical pain management, within the licensed territories.

“We are excited to announce another strategic partnership that advances our 5x30 growth strategy and reinforces our commitment to expanding patient access to best-practice opioid-sparing postsurgical pain management,” said Frank D. Lee, chief executive officer of Pacira BioSciences. “With Molteni Farmaceutici’s longstanding leadership in pain management and extensive distribution network across Europe, they are ideally positioned to unlock EXPAREL’s full potential in key European markets.”

“This agreement is highly complementary with Molteni’s strategic priorities, and represents an important step in Molteni’s international growth and expansion strategy, while adding an innovative and differentiated medicine to our portfolio. We believe EXPAREL represents a compelling opportunity to address the significant unmet need for effective postsurgical pain management across Europe,” said Gianluca Corbinelli, chief executive officer at Molteni Farmaceutici. “We look forward to bringing this important treatment to more patients and healthcare providers across the region.”

Under the terms of the agreement, Pacira will receive an undisclosed upfront payment, a supply price, and royalties on future commercial sales by Molteni Farmaceutici in licensed territories. Pacira will manufacture EXPAREL. Molteni Farmaceutici will lead regulatory, market access, and commercialization activities across the licensed territories, leveraging its established leadership and proven track record in pain management. Molteni Farmaceutici plans to launch EXPAREL sequentially, beginning with Italy, Germany, Austria, and Poland, and pursue approval in Switzerland. The first commercial sale is expected in 2027.

This partnership reflects the companies’ shared commitment to improving postsurgical pain management by combining Pacira’s differentiated product with Molteni Farmaceutici’s strong commercial execution capabilities and deep understanding of local European markets.

About EXPAREL****® (bupivacaine liposome injectable suspension)

EXPAREL is indicated to produce postsurgical local analgesia via infiltration in patients aged 6 years and older, and postsurgical regional analgesia via an interscalene brachial plexus block in adults, a sciatic nerve block in the popliteal fossa in adults, and an adductor canal block in adults. The safety and effectiveness of EXPAREL have not been established to produce postsurgical regional analgesia via other nerve blocks besides an interscalene brachial plexus nerve block, a sciatic nerve block in the popliteal fossa, or an adductor canal block. The product combines bupivacaine with multivesicular liposomes, a proven product delivery technology that delivers medication over a desired time period. EXPAREL represents the first and only multivesicular liposome local anesthetic that can be utilized in the peri- or postsurgical setting. By utilizing the multivesicular liposome platform, a single dose of EXPAREL delivers bupivacaine over time, providing significant reductions in cumulative pain scores with up to a 78 percent decrease in opioid consumption; the clinical benefit of the opioid reduction was not demonstrated. Additional information is available at www.EXPAREL.com.

Important Safety Information about EXPAREL for Patients

EXPAREL should not be used in obstetrical paracervical block anesthesia. In studies in adults where EXPAREL was injected into a wound, the most common side effects were nausea, constipation, and vomiting. In studies in adults where EXPAREL was injected near a nerve, the most common side effects were nausea, fever, and constipation. In the study where EXPAREL was given to children, the most common side effects were nausea, vomiting, constipation, low blood pressure, low number of red blood cells, muscle twitching, blurred vision, itching, and rapid heartbeat. EXPAREL can cause a temporary loss of feeling and/or loss of muscle movement. How much and how long the loss of feeling and/or muscle movement depends on where and how much of EXPAREL was injected and may last for up to 5 days. EXPAREL is not recommended to be used in patients younger than 6 years old for injection into the wound, for patients younger than 18 years old, for injection near a nerve, and/or in pregnant women. Tell your health care provider if you or your child has liver disease, since this may affect how the active ingredient (bupivacaine) in EXPAREL is eliminated from the body. EXPAREL should not be injected into the spine, joints, or veins. The active ingredient in EXPAREL can affect the nervous system and the cardiovascular system; may cause an allergic reaction; may cause damage if injected into the joints; and can cause a rare blood disorder.
