NEW HOPE, Pa., Nov. 10, 2026 (GLOBE NEWSWIRE) — Orchestra BioMed Holdings, Inc. (Nasdaq: OBIO, “Orchestra BioMed” or the “Company”), a biomedical innovation company accelerating high-impact technologies to patients through strategic collaborations with market-leading global medical device companies, today announced financial results for the third quarter ended September 30, 2026, and provided a business update on its two pivotal-stage investigational cardiovascular programs: Atrioventricular Interval Modulation Therapy (“AVIM Therapy”) for the treatment of uncontrolled hypertension, for which the Company has a strategic collaboration with Medtronic (NYSE: MDT) for the treatment of pacemaker-indicated patients, and Virtue® Sirolimus AngioInfusion™ Balloon (“Virtue SAB”) for the treatment of coronary artery disease.

David Hochman, Chairman and Chief Executive Officer of Orchestra BioMed, stated, “With the completion of enrollment of the BACKBEAT Trial, AVIM Therapy is nearing pivotal primary endpoint results. Alongside our collaborators at Medtronic, we now move to the completion of three-month follow-up in all patients, locking the primary endpoint database, and submitting a robustly powered data set for late-breaking presentation at HRS 2027 in May. We believe the results from the BACKBEAT Trial could set AVIM Therapy on a clear course to redefining the clinical impact of cardiac pacing and provide a powerful new therapeutic option for millions of higher-risk hypertensive patients who remain above blood pressure target despite medication.”

Hochman continued, “The third quarter also saw Virtue Sirolimus AngioInfusion™ Balloon advance in its own IDE pivotal, randomized trial. The Virtue^® Trial is testing Virtue SAB’s fundamentally different approach to arterial drug delivery, liquid infusion of SirolimusEFR™ directly into the vessel wall without the need for a fragile balloon coating. We are also grateful to our new and existing shareholders that participated in the oversubscribed public equity offering we closed yesterday. The net proceeds from our public offering along with the over $100 million we had at the end of the quarter provide funding through 2028. We are in a strong position to deliver key value-creating milestones for both pivotal stage programs and support Medtronic as they drive toward potential global commercialization of AVIM Therapy. We look forward to showcasing both of our high-impact therapeutic device platforms at our investor R&D Day this Thursday, where leading physician investigators will join us to examine the clinical and commercial potential of AVIM Therapy and Virtue SAB.”

Q3 2026 and Recent Business Highlights:

• Completed enrollment in the BACKBEAT Trial in collaboration with Medtronic. A total of 349 patients with uncontrolled hypertension and an implanted dual-chamber pacemaker were randomized across 92 sites in 15 countries. Orchestra BioMed and Medtronic intend to submit primary endpoint results for late-breaking presentation consideration at HRS 2027.
• Received written confirmation from FDA that Medtronic’s marketing submission for AVIM Therapy will be a PMA supplement. The submission is planned to be made promptly following presentation of the primary endpoint results of the BACKBEAT Trial, assuming positive trial results.
• Advanced site activation and patient enrollment in the Virtue Trial, the Company’s U.S. IDE pivotal trial comparing Virtue SAB head-to-head with the commercially available AGENT™ paclitaxel-coated balloon for coronary in-stent restenosis (“ISR”). The prospective, multicenter, randomized, single-blind, non-inferiority trial has a planned enrollment of approximately 740 patients, with an enrollment completion target date by the end of 2027.
  
• Virtue SAB mechanistic and clinical evidence presented at Transcatheter Cardiovascular Therapeutics 2026. On November 1, 2026, Allen Jeremias, MD, Co-Principal Investigator of the Virtue Trial, presented Virtue SAB’s differentiated mechanism of action for infusing a large liquid volume of submicron, particle-encapsulated SirolimusEFR™ directly into the vessel wall. Dr. Jeremias also outlined existing preclinical and clinical evidence and the pivotal IDE trial design.
• AVIM Therapy was featured in two sessions at HRX Live 2026 in Atlanta, including a sponsored roundtable on the Medtronic–Orchestra BioMed strategic collaboration and a panel exploring the expanding role of permanent cardiac pacing beyond bradycardia. The discussions highlighted AVIM Therapy’s mechanism of action, clinical evidence and potential in hypertensive heart disease. A recording of the roundtable is available on the Company’s website.
• Received a $6.1 million milestone payment on September 14, 2026, in connection with Haemonetics Corporation’s (NYSE: HAE) acquisition of Vivasure Medical Limited (“Vivasure”). Together with approximately $5 million received in January 2026, total cash proceeds received from the transaction are approximately $11 million. The FDA recently approved the PerQseal® Elite vascular closure system, originally developed by Vivasure, for large-bore arterial procedures.

Public Offering

On November 9, 2026, the Company closed an underwritten public offering of 17,250,000 shares of its common stock at a price to the public of $5.00 per share, resulting in net proceeds to the Company of approximately $80.5 million (including proceeds from the underwriters’ full exercise of their option to purchase additional shares), after deducting underwriting discounts and commissions and estimated offering expenses (the “Public Offering”).

R&D Day: Thursday, November 12, 2026

Company leadership, leading cardiologists and trial investigators will discuss the clinical and treatment burden associated with uncontrolled hypertension in pacemaker-indicated patients and restenosis in coronary stent interventions, the potential for AVIM Therapy and Virtue SAB to address these unmet needs, key upcoming clinical milestones and the commercial potential of AVIM Therapy and Virtue SAB. Physician speakers include Vivek Reddy, MD, Marat Fudim, MD, Dean Kereiakes, MD, and Allen Jeremias, MD.

Financial Results for the Third Quarter Ended September 30, 2026

• Cash and cash equivalents and Marketable securities totaled $101.9 million as of September 30, 2026, not including the $80.5 million in net proceeds from the Public Offering.
• Net cash used in operating activities and for the purchase of fixed assets was $19.9 million during the third quarter of 2026, compared with $14.9 million for the third quarter in 2025, with the primary drivers being increased research and development costs, including clinical trial activities, as well as personnel and consulting expenditures during the third quarter of 2026.
• Research and development expenses for the third quarter of 2026 were $17.7 million, compared with $14.0 million for the third quarter in 2025, which represents an increase of 26%. The increase was primarily due to additional costs associated with the ongoing BACKBEAT Trial and to advance the Virtue SAB program, including the Virtue Trial.
• Selling, general and administrative expenses for the third quarter of 2026 were $5.6 million, compared with $7.1 million for the third quarter of 2025, which represents a decrease of 21%. The decrease was primarily due to a decrease in legal and professional fees.
