Q: TMDX is in the business of delivering viable human organs for transplant operations. Their technology markedly improves organ viability compared to the previous methodology of placing organs on ice. Future competitors must demonstrate via clinical trials that their technology is significantly better than that of TMDX. Seems like a decent moat. TMDX took on further debt to by a small airline to facilitate organ delivery which was being hampered by lack of reliable air transport. I would appreciate your expertise in determining if TMDX has a valid business model that warrants investment in their stock at its current price.
