David Hochman, Chairman and Chief Executive Officer of Orchestra BioMed stated, “We continued to make meaningful advancements across our late-stage cardiovascular pipeline during the first quarter. Along with the achievement of recently announced important regulatory, clinical and financing milestones, we are pleased to provide clarity on the expected timeline for the BACKBEAT Trial highlighting objectives for enrollment completion, late-breaking clinical trial presentation, and plans for potential regulatory submissions by our strategic collaborator Medtronic. With increasingly strong momentum continuing in the BACKBEAT Trial and the AVIM Therapy program, and great progress for the Virtue Trial and Virtue SAB, our team is excited about the significant value inflection points that lie ahead for Orchestra BioMed.” Q1 2026 and Recent Business Highlights: Provided overall update on the BACKBEAT Trial timeline, targeting enrollment completion by the end of the third quarter of 2026 and announced plans with Medtronic to pursue presentation of primary endpoint data as a late-breaking clinical trial presentation at a major cardiovascular conference in the second quarter of 2027, assuming primary endpoints are met. The updated timeline is supported by FDA approval of a reduction in sample size for the BACKBEAT Trial to a target total of 284 evaluable randomized subjects, with a total enrollment target of 316 patients accounting for potential loss to follow-up. FDA granted AVIM Therapy a second FDA Breakthrough Device Designation (“BDD”) specific to patients with uncontrolled hypertension despite the use of anti-hypertensive medications, and an indication for a pacemaker. The BDDs granted to AVIM Therapy collectively apply to indications that encompass both the broader population of patients with uncontrolled hypertension despite medication and increased cardiovascular risk, as well as the specific pacemaker-indicated population with uncontrolled hypertension being evaluated in the BACKBEAT Trial, representing a U.S. population of over 7.7 million patients.BDD can support enhanced reimbursement pathways, including potential eligibility for New Technology Add-on Payment and Transitional Pass-Through payment, which can facilitate broader, more timely patient access and provider adoption. Received $35 million in strategic capital under previously disclosed agreements with Medtronic and Ligand (Nasdaq: LGND). Received $20 million from Medtronic as payment for a secured subordinated promissory note convertible to capped prepaid revenue share, fulfilling Medtronic’s previously disclosed funding commitment. This brings Medtronic’s total capital contribution to Orchestra BioMed to nearly $82 million including prior equity investments, supporting the planned completion of the BACKBEAT Trial.Received $15 million tranche payment from Ligand associated with the previously disclosed Royalty Purchase Agreement, bringing total capital received from Ligand to $40 million to date in exchange for tiered royalty interest in certain future AVIM Therapy and Virtue SAB revenue, as well as an equity investment. Presented AVIM Therapy clinical and mechanistic data at HRS 2026, including pre-randomization data from the MODERATO II pilot study in which AVIM Therapy demonstrated a mean immediate reduction in office systolic blood pressure of 13.2 mmHg upon activation, with 97% of patients achieving a 5 mmHg or greater blood pressure reduction upon AVIM Therapy activation.Advanced site activation and patient enrollment in the Virtue Trial, a multi-center, prospective, randomized head-to-head IDE registrational clinical trial comparing Virtue SAB with the commercially available AGENT™ paclitaxel-coated balloon for the treatment of coronary in-stent restenosis. Financial Results for the First Quarter Ended March 31, 2026 Cash and cash equivalents and Marketable securities totaled $94.4 million as of March 31, 2026. On May 1, 2026, we received $35 million, which includes $20 million from Medtronic and $15 million from Ligand pursuant to the terms of agreements with those parties.Net cash used in operating activities and for the purchase of fixed assets was $22.4 million during the first quarter of 2026, compared with $16.7 million for the first quarter in 2025, with the primary drivers being increased research and development costs, including clinical trial activities, as well as personnel and consulting expenditures, which include non-recurring payments, during the first quarter of 2026.Revenue for the first quarter of 2026 was $0.1 million, compared with $0.9 million for the first quarter in 2025. The decrease was primarily due to the elimination of recognized revenue from our prior distribution agreement with Terumo, which was terminated in October 2025.Research and development expenses for the first quarter of 2026 were $15.8 million, compared with $13.5 million for the first quarter in 2025, which represents an increase of 17%. 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 first quarter of 2026 were $6.4 million, compared with $6.3 million for the first quarter of 2025, which represents an increase of 2%. The increase was primarily due to an increase in professional fees.Net loss attributable to common stockholders for the first quarter of 2026 was $20.7 million, or ($0.33) per share, compared with a net loss attributable to common stockholders of $18.8 million, or ($0.49) per share, for the first quarter of 2025, which represents an increase of 10%.

About AVIM Therapy AVIM Therapy is an investigational therapy compatible with standard dual-chamber pacemakers designed to substantially and persistently lower blood pressure. It has been evaluated in pilot studies in patients with hypertension who are also indicated for a pacemaker. MODERATO II, a double-blind, randomized pilot study, showed that patients treated with AVIM Therapy experienced net reductions of 8.1 mmHg in 24-hour ambulatory systolic blood pressure (aSBP) and 12.3 mmHg in office systolic blood pressure (oSBP) at six months when compared to control patients. In addition to reducing blood pressure, clinical results using AVIM Therapy demonstrate improvements in cardiac function and hemodynamics. The BACKBEAT (BradycArdia paCemaKer with atrioventricular interval modulation for Blood prEssure treAtmenT) global pivotal trial is evaluating the safety and efficacy of AVIM Therapy in lowering blood pressure in patients who have systolic blood pressure above target despite anti-hypertensive medication and who are indicated for or have recently received a dual-chamber cardiac pacemaker. AVIM Therapy has been granted two Breakthrough Device Designations by the FDA for the treatment of uncontrolled hypertension in patients who have increased cardiovascular risk. About Virtue SAB Virtue SAB is designed to deliver a proprietary extended-release formulation of sirolimus, SirolimusEFR™ through a non-coated microporous AngioInfusion™ Balloon that protects the drug in transit to consistently deliver a large liquid dose overcoming certain limitations of drug-coated balloons. SirolimusEFR delivered by Virtue SAB has been shown in published preclinical series involving hundreds of arterial deliveries to achieve sustained tissue levels well above the known required therapeutic tissue concentration for inhibiting restenosis (1 ng/mg tissue) for the entire critical healing period of approximately 30 days. Virtue SAB demonstrated positive three-year clinical data in coronary ISR in the SABRE study, a multi-center prospective, independent core lab-adjudicated pilot clinical study of 50 patients conducted in Europe. Virtue SAB has been granted Breakthrough Device Designation by the FDA for specific indications relating to coronary ISR, coronary small vessel disease and peripheral artery disease below-the-knee.
