ANDOVER, Mass., Sept. 22, 2025 /PRNewswire/ -- TransMedics Group, Inc. ("TransMedics") (Nasdaq: TMDX), a medical technology company that is transforming organ transplant therapy for patients with end-stage lung, heart, and liver failure, today announced a strategic collaboration with Mercedes-Benz Group AG to deploy a first-of-its-kind fleet of modern, purpose-built Mercedes-Benz V-class vehicles dedicated exclusively to organ transportation across Italy.

The strategic collaboration supports TransMedics' broader commercial strategy to replicate its successful U.S. NOP™ in Europe by building a dedicated air and ground logistics network that complements the innovative TransMedics OCS™ perfusion platform and clinical services. The upcoming launch could lay the foundation for a broader, multi-country European transplant dedicated logistics network designed to expand access to donor organs and help more patients in need of transplantation.

As part of the collaboration, TransMedics will deploy and staff several dedicated Mercedes-Benz V-Class vehicles across four major Italian NOP hubs in Milan, Rome, Padua, and Bari. The vans are equipped with advanced safety specifications which meet stringent handling requirements of transplant logistics and provide a secure environment for the organs, physicians, and equipment during mission transport.

The initial Italian NOP hubs are expected to launch before the end of 2025. Each hub will be equipped with OCS Lung, Heart, and Liver Systems and staffed by an experienced team of clinical perfusionists. TransMedics aims to provide 24/7 technological, clinical, and logistical support to transplant centers, procurement organizations, and surgical teams to increase donor organ utilization for transplants across Italy. The Italian National Command Center will operate from TransMedics' NOP hub in Santa Giulia, Milan.

"This collaboration between TransMedics and Mercedes-Benz underscores our shared focus on delivering the highest-quality technology and services to save lives," said Waleed Hassanein, M.D., President, and Chief Executive Officer of TransMedics. "Our NOP initiative in Italy is a crucial first step towards expanding global access to our life-saving OCS technology to patients in need."

Dario Albano, Managing Director of Mercedes-Benz Vans Italia added, "We are proud to support TransMedics with our first-class vehicles engineered for professional, mission-critical operations. Together we aim to raise the bar for medical transport, enabling clinical teams to focus on what matters most—saving lives."
