<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;"><b>Sunnyvale, Calif.</b>&nbsp;&#8211;<b> July 16, 2025 -</b>&nbsp;<u>BioCardia, Inc.</u>&nbsp;[Nasdaq: BCDA], a global leader in cellular and cell-derived therapeutics for the treatment of cardiovascular and pulmonary diseases, announced today that Henry Ford Health in Detroit, Michigan is now enrolling patients with ischemic HFrEF in the Company&#8217;s ongoing pivotal CardiAMP HF II trial.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family: &quot;Times New Roman&quot;; font-size: 10pt; font-variant: normal; margin: 0pt;">&#8220;The CardiAMP HF cell therapy trials are important for patients with ischemic heart failure in need of new therapies,&#8221; said Gerald Koenig, M.D., Director of the Cardiac Catheterization Laboratory, Henry Ford West Bloomfield Hospital, and Principal Investigator of CardiAMP HF II for Henry Ford Health System.&nbsp;&#8220;Together with the other investigators in this trial, we hope to confirm the promising results in the CardiAMP HF trial and enable our patients early access to this novel investigational autologous cell therapy.&#8221;</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;">The CardiAMP HF II trial is a confirmatory trial of autologous bone marrow derived mononuclear cell therapy for patients suffering from ischemic heart failure. The investigational therapy is intended to promote microvascular repair, reduce fibrosis, and increase capillary density. Patients who qualify for the study have cells harvested the day of the procedure, processed at their bedside, and delivered in the same procedure using minimally invasive catheter delivery systems. At the end of the procedure, nothing is left behind other than high doses of the patients&#8217; own cells adjacent to damaged zones in their hearts.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;">&#8220;We are delighted to continue our partnership with Dr. Koenig and the world class cardiovascular clinical research team at Henry Ford Health in CardiAMP HF II,&#8221; said Peter Altman, PhD, BioCardia&#8217;s CEO. &#8220;We share the common mission of enhancing therapies to treat cardiovascular disease. The results from our completed TABMMI, TACHFT, and CardiAMP HF trials underlie the potential to improve the lives of patients with heart failure and the families who care for them.&#8221;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;"><b>About the CardiAMP Heart Failure II Study</b></p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;">CardiAMP HF II is a 250-patient randomized multicenter procedure placebo-controlled study of the CardiAMP autologous cell therapy as a one-time treatment for patients with ischemic HFrEF on guideline directed medical therapy having elevated NTproBNP. The study is intended to confirm the safety and efficacy results in these patients observed in the CardiAMP HF study. The CardiAMP HF II study uses a similar three-tier composite primary outcome measure to CardiAMP HF, with tier 1 all cause death, tier 2 nonfatal major adverse cardiac events, and with tier 3 using a validated quality of life patient self-assessment instrument. In CardiAMP HF, this composite efficacy endpoint was achieved with statistical significance in the patients with elevated NTproBNP that are the focus of the CardiAMP HF II study.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;">According to the Centers for Disease Control and Prevention, about 6.2 million adults in the U.S. over 20 years old have heart failure. It is the cause of an estimated one in eight deaths in U.S., and each year, there are approximately 960,000 new cases of heart failure diagnosed, according to the American Heart Association. Current treatments for heart failure include lifestyle changes, medications, and certain devices or surgical procedures. While improving quality of life and longevity for many, these treatments often fail to halt the progression of the disease, and some patients do not respond well, experience adverse effects from medications, or have complications from invasive procedures, often requiring ongoing and more aggressive interventions.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;">Granted FDA Breakthrough designation, CardiAMP Cell Therapy uses a patient&#8217;s own bone marrow cells delivered to the heart in a minimally invasive, catheter-based procedure to stimulate the body&#8217;s natural healing response to increase capillary density, reduce tissue fibrosis, and ultimately treat microvascular dysfunction. The mechanisms that lead to microvascular dysfunction, including fibrotic, inflammatory, apoptotic, and endothelial dysfunction, are all targets of CardiAMP cell therapy, largely through production of growth factors, cytokines, chemokines, and other factors that directly counteract each of these mechanisms.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt;">The CardiAMP clinical development for heart failure is supported by the Maryland Stem Cell Research Fund and is reimbursed by Centers for Medicare and Medicaid Services (CMS). CAUTION - Limited by United States law to investigational use.</p>
