Mesoblast Ltd (MESO) shares rallied Friday after the biotech company delivered impressive revenue numbers for its flagship cell therapy, demonstrating that niche treatments can still generate meaningful commercial traction.
The Revenue Story
Mesoblast reported $35.1 million in gross revenue from Ryoncil (remestemcel-L-rknd) for the quarter ending December 31, 2025. That's a 60% increase from the September quarter, which is the kind of sequential growth that gets investors excited.
Ryoncil holds a unique position in the market. It's the first mesenchymal stromal cell therapy ever approved by the FDA, and it remains the only FDA-approved treatment for children under 12 suffering from steroid-refractory acute graft-versus-host disease. That's a serious condition that affects pediatric patients who've undergone bone marrow transplants, and until Ryoncil came along, there weren't many good options.
What makes this particularly interesting is where the company is headed next. Ryoncil is now advancing through trials as a second-line treatment option for adults with the same condition. The adult market is roughly three times larger than the pediatric segment, which means the revenue opportunity could expand considerably if the trials succeed and the FDA grants approval.
Financial Positioning
The revenue growth comes at a time when Mesoblast has been working to strengthen its balance sheet. The company recently locked in a $125 million financing facility with its largest shareholder, reducing its cost of capital and providing more flexibility for commercial partnerships and ongoing development efforts.
