Everyone here has a story. For many of us, cancer is personal. It has touched our families, our friends, and our lives. That is what makes the work we do matter so deeply.

The technology, the platform, and the real-world impact are tangible. Some of our own family members have been treated on Mevion systems. That makes it easy to show up every day.

As we look back on 2025, we’re proud of what this year represents for Mevion - progress, partnership, and purpose.

From new proton therapy installs expanding access to advanced cancer care, to new partnerships that continue to push innovation forward, this year was defined by momentum. A major milestone came with the FDA 510(k) clearance of the MEVION S250-FIT™ system, reinforcing our commitment to delivering compact, efficient, and patient-centric proton therapy solutions.

We were also honored to welcome impactful delegate visits to our headquarters, where we shared firsthand how U.S.-based innovation and manufacturing are shaping the future of cancer treatment. These moments underscored the importance of collaboration between industry, community, and leadership.

Above all, 2025 reflected the continued growth and advancement of proton therapy and the role we all play to make it more accessible, more practical, and more powerful for providers and patients worldwide.

Thank you to our customers, partners, and the Mevion team for making this year one to remember. Here’s to advancing access in the year ahead. 🚀
