"The need for resilient, efficient power across the defense sector continues to grow," said Abdul Subhani. "Hyliion's technology has already generated strong interest from the U.S. military, and I believe it can play an important role in strengthening our nation's energy resilience and supporting next-generation defense capabilities. I'm excited to help the company deepen its engagement across the defense community."

"As demand for the KARNO™ technology continues to grow across defense applications, Abdul's experience at the intersection of technology and national security will be invaluable," said Thomas Healy, Founder and Chief Executive Officer of Hyliion. "His insight and relationships will help strengthen our engagement across the defense community as we continue expanding our military business."

Hyliion has rapidly expanded its defense business, securing multiple contracts with the U.S. Navy while advancing a growing pipeline of military opportunities. The Company expects to secure an additional $40–50 million of military contracts during 2026. Subhani's appointment further strengthens Hyliion's ability to support this growth as the Company expands deployment of the KARNO technology across defense and national security applications.
