&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;MESOBLAST REPORTS RYONCIL® NET REVENUES OF US$30.3M AND IMPROVED NET OPERATING CASH SPEND FOR THE QUARTER TO US$4.1 MILLION Achieved Patient Recruitment Target in Pivotal Phase 3 Trial for Chronic Low Back Pain Activity Report for Quarter Ended March 31, 2026 (Appendix 4C) New York, USA: April 29 and Melbourne, Australia: April 30, 2026: Mesoblast Limited (ASX:MSB; Nasdaq:MESO), global leader in allogeneic cellular medicines for inflammatory diseases, today provided highlights of its recent activities for the third fiscal quarter ended March 31, 2026. "We've had a busy and exciting March quarter marked by a series of major achievements. Ryoncil® revenues are now approaching US$100 million since last year's launch, we have substantially improved our net operating cash spend, our pivotal trial in inflammatory back pain has successfully achieved its patient recruitment target, and we have bolstered our long-term leadership in the field by acquiring genetically modified technology for precision-enhanced cell therapy products," said Dr. Silviu Itescu, Mesoblast Chief Executive. FINANCIAL HIGHLIGHTS FOR QUARTER ENDED MARCH 31, 20261 • Ryoncil® gross sales for the quarter were US$35.3 million, and net revenues were US$30.3 million.1 • Strong sales in February and March offset holiday seasonality in January. • Revenue generated during this first year of Ryoncil® launch approaches US$100 million. • Net operating cash spend for the quarter was US$4.1 million. The reduction in net operating cash spend was driven by receipts of US$34.6 million and tight control of operating expenses. • Mesoblast had US$122 million of cash at March 31, 2026. OPERATIONAL HIGHLIGHTS • Achieved patient recruitment target in pivotal phase 3 trial of second-generation product rexlemestrocel-L for chronic low back pain (CLBP). • Held inaugural R&D day on April 8th in New York. A replay of the event is available here and presentation materials here. • At the R&D day Mesoblast highlighted its label extension strategy for Ryoncil® in adult and pediatric rare diseases, provided an update on near- and mid-term blockbuster opportunities in inflammatory back pain and heart failure, showcased leadership in allogeneic cell therapy innovation, and outlined commercial strategies for continued revenue growth. • The trial for label extension of our flagship product Ryoncil® in adults with SR-aGvHD was cleared to begin by FDA, by data safety monitoring board (DSMB), and by central institutional review board (IRB) with first sites to be activated this quarter. • FDA granted Investigational New Drug (IND) clearance to proceed directly to a registrational trial evaluating Ryoncil® in Duchenne's muscular dystrophy (DMD), which affects approximately 15,000 children in the U.S. • In addition, at the R&D day, Mesoblast unveiled next generation mesenchymal stromal cell (MSC) strategies including announcing the acquisition of an exclusive worldwide license to a patented chimeric antigen receptor (CAR) technology platform for precision-enhanced augmentation of therapeutic MSC products. • This CAR technology provides Mesoblast with an immediate opportunity to generate products with even greater potency for ulcerative colitis or Crohn's disease. In addition, Mesoblast plans to use CAR-MSC engineered to express CD19 on their surface to induce remission in Lupus Nephritis and other B cell autoimmune diseases where durable, effective and safe immunomodulation is highly desirable.

About Mesoblast Mesoblast (the Company) is a world leader in developing allogeneic (off-the-shelf) cellular medicines for the treatment of severe and life-threatening inflammatory conditions. The therapies from the Company's proprietary mesenchymal lineage cell therapy technology platform respond to severe inflammation by releasing anti-inflammatory factors that counter and modulate multiple effector arms of the immune system, resulting in significant reduction of the damaging inflammatory process. Mesoblast's Ryoncil® (remestemcel-L-rknd) for the treatment of steroid-refractory acute graft versus host disease (SR-aGvHD) in pediatric patients 2 months and older is the first FDA-approved mesenchymal stromal cell (MSC) therapy. Please see the full Prescribing Information at www.ryoncil.com. Mesoblast is committed to developing additional cell therapies for distinct indications based on its remestemcel-L and rexlemestrocel-L allogeneic stromal cell technology platforms. Ryoncil® is being developed for additional inflammatory diseases including SR-aGvHD in adults and biologic-resistant inflammatory bowel disease. Rexlemestrocel-L is being developed for heart failure and chronic low back pain. The Company has established commercial partnerships in Japan, Europe and China. About Mesoblast intellectual property: Mesoblast has a strong and extensive global intellectual property portfolio, with over 1,000 granted patents or patent applications covering mesenchymal stromal cell compositions of matter, methods of manufacturing and indications. These granted patents and patent applications provide commercial protection extending through to at least 2044 in all major markets.
