Heron Pipeline US FDA Approved for postsurgical analgesia for up to 72 hours* ZYNRELEF™ (bupivacaine and meloxicam) extended-release solution Acute Care CINV: Chemotherapy-induced nausea and vomiting. SUSTOL® (granisetron) extended-release injection is indicated in combination with other antiemetics in adults for the prevention of acute and delayed nausea and vomiting associated with initial and repeat courses of moderately emetogenic chemotherapy (MEC) or anthracycline and cyclophosphamide (AC) combination chemotherapy regimens. CINVANTI® (aprepitant) injectable emulsion, in combination with other antiemetic agentsis indicated in adults for the prevention of acute and delayed nausea and vomiting associated with initial and repeat courses of highly emetogenic cancer chemotherapy (HEC) including high-dose cisplatin as a single-dose regimen, delayed nausea and vomiting associated with initial and repeat courses of moderately emetogenic cancer chemotherapy (MEC) as a single-dose regimen, and nausea and vomiting associated with initial and repeat courses of MEC as a 3-day regimen. CINVANTI has not been studied for treatment of established nausea and vomiting. ZYRNELEF (bupivacaine and meloxicam) extended-release solution is indicated in adults for soft tissue or periarticular instillation to produce postsurgical analgesia for up to 72 hours after bunionectomy, open inguinal herniorrhaphy, and total knee arthroplasty. Safety and efficacy have not been established in highly vascular surgeries, such as intrathoracic, large multilevel spinal, and head and neck procedures. Under Investigation for Postoperative Pain HTX-034 (bupivacaine/meloxicam/aprepitant) HTX-034 and HTX-019 are investigational new drugs and are not approved by the FDA SUSTOL® (granisetron) extended-release injection Oncology Care US FDA Approved for CINV Prevention* HTX-019 (aprepitant) injectable emulsion

In 2020, drug overdoses were linked to more than 90,000 deaths the highest number ever recorded in a single year.3 Why Approval of ZYNRELEF is so Important Postoperative Opioids Can Be a Doorway to Addiction > 2 million Americans may become persistent opioid users annually after surgery. 1 More than 50 million surgical procedures happen in the United States.1 67% of patients filled an opioid prescription between 30 days before through 14 days after surgery.2* In addition, most patients take fewer opioids than the amount prescribed after surgery, resulting in excess opioid pills that are accessible to others.4 80% of patients report unused opioid tablets4 Up to 77% of opioid pills remain inside the home in unsecured locations4 51% of nonmedical users of opioids received them from friends and family5 References: 1.

Indication ZYNRELEF is indicated in adults for soft tissue or periarticular instillation to produce postsurgical analgesia for up to 72 hours after bunionectomy, open inguinal herniorrhaphy, and total knee arthroplasty. Limitations of Use Safety and efficacy have not been established in highly vascular surgeries, such as intrathoracic, large multilevel spinal, and head and neck procedures. ZYNRELEF Approved Indications and Limitations of Use

ZYNRELEF is first modified-release local anesthetic to be classified by FDA as an “extended-release” product ZYNRELEF only product to demonstrate superiority to immediate release bupivacaine HCL for 72 hours 72-hour duration in the indication statement Registrational studies in clinical data section in indicated procedures include pain curves showing 72-hour duration of activity and superiority to standard of care Focus is on opioid-free results in clinical data section as both statistically superior and clinically meaningful Standard NSAID class warnings included, with modifications due to single-dose local application allowing for additional NSAID use in multimodal analgesia (MMA) with monitoring Unique Labeling Attributes for ZYNRELEF Extended-Release Solution

Rather than approving a broad indication based on 1 soft tissue and 1 bony surgical model, FDA approved other modified-release local anesthetics for specific indications based on positive randomized, controlled trials in specific surgical procedures starting in 2020. Heron sought advice from FDA throughout development to discuss requirements for a broad label for ZYNRELEF, the only modified-release local anesthetic to demonstrate superiority to bupivacaine solution Based on these discussions with FDA, Heron believed that the studies submitted in the ZYNRELEF NDA would be sufficient to obtain a broad indication One week prior to PDUFA, FDA informed Heron more PK and safety data would be required to support additional surgical procedures Heron has multiple studies in process intended to support expanded labelling FDA Approach to Modified-Release Local Anesthetics Changed Following Withdrawal of Guidance on Analgesic Indications

Strategic Imperative #2 Raise the bar with ZYNRELEF’s superior value proposition to expedite access

ZYNRELEF’s Unprecedented Value Proposition *Medicare Reimbursement only, pass-through status is for 3 years. GPO = Group Purchasing Organization. HOPD = Hospital Outpatient Department. ZYNRELEF Go-to-Market Strategy Comparison

a. Heron will apply for transitional pass-through status for ZYNRELEF. Typically, pass-through status is for 3 years. b. Exparel (bupivacaine liposome injectable suspension) is a trademark of Pacira Pharmaceuticals, Inc. c. ZYNRELEF will be reimbursed at WAC + 3% until ASP is established. d. Effective January 1, 2019, ASCs are reimbursed at ASP + 6% for non-opioid postoperative pain management drugs, like ZYNRELEF, when administered during a surgical procedure. HOPD: hospital outpatient department. AWP: average wholesale price. ASP: average selling price. ASC: ambulatory surgical center. WAC: wholesale acquisition cost. Heron will apply for a J-code to facilitate separate reimbursement with expected grant date of January 1, 2022 Like all new products, until CMS assigns a permanent code, commercial payers will require a miscellaneous code (J3490 or C9399) for ZYNRELEF Heron Connect helps customers navigate coding and reimbursement for ZYNRELEF Medicare: ZYNRELEF Is Reimbursed Separately in HOPD and ASC Heron will apply for a C-Code with expected grant date of October 1, 2021 Commercial Reimbursement Varies by Payer ZYNRELEF Reimbursement & Pricing Creates Economic Benefits Across All Settings of Care

ZYNRELEF’s Significant Economic Benefits Designed to Support Rapid Share Conversion and Broad Access *Comparing WAC acquisition cost to NCR reimbursement under Medicare/Exparel NCR assumes ASCs purchasing at WAC. †Medicare NCRs are shown based on estimated ASP reimbursement for ZYNRELEF and Exparel Q2’21 published ASP reimbursement. WAC: wholesale acquisition cost. NCR: net cost recovery. HOPD: hospital outpatient department. ASC: ambulatory surgical center. **DRG Research Pricing Research 2018 and Mock P&T Research 2019 ZYNRELEF Economic Benefit vs. Exparel* 340B accounts: >$415 (400 mg to 266 mg) and >$223 (200 mg to 133 mg) HOPD accounts: >$354 (400 mg to 266 mg) and >$192 (200 mg to 133 mg) Research has shown all customer segments were more sensitive to and favored acquisition cost over reimbursement** Does not include additional cost of bupivacaine to admix with Exparel to achieve efficacy
