Aspen Aerogels, Inc. (NYSE: ASPN) ("Aspen", the "Company"), a technology leader in aerogel-based sustainability and electrification solutions, has been named an Overdrive Award winner as part of GM's 30th Annual Supplier of the Year awards. Aspen's award for Launch Excellence recognizes the Company's key role in GM's thermal propagation strategy. Aspen's industry leading PyroThin^® thermal barrier aerogel technology is integrated into GM's Ultium battery platform. 

"We are deeply honored to receive this prestigious recognition from GM," said Aspen President and CEO Don Young. "The Aspen team values our deep and productive relationship with GM, and we are particularly proud to play an important role in the Ultium battery platform.

GM celebrated honorees at an awards ceremony in Phoenix, Arizona, earlier this week.

"This year's Supplier of the Year event was special not only because it's the 30th anniversary of the program, but because it provided us with the opportunity to recognize our suppliers for persevering through one of the most challenging years the industry has ever faced," said Shilpan Amin, GM vice president, Global Purchasing and Supply Chain.

About Aspen Aerogels' PyroThin® Thermal Barriers

PyroThin^® is an ultrathin, lightweight, high-temperature thermal insulation and fire barrier engineered to mitigate thermal runaway propagation at cell-to-cell, module, and pack barrier level. PyroThin's flexible and robust format accommodates a lithium-ion battery's daily breathing and progressive swelling as it ages. Even at the end-of-life, PyroThin has sufficient thermal resistance to mitigate thermal propagation. Use of PyroThin thermal barriers in lithium-ion battery packs helps automotive manufacturers meet critical safety goals without sacrificing drive range. PyroThin's aerogel technology evolved from more than two decades of thermal protection development in energy infrastructure, chemical processing, and transportation applications, including internal combustion engine and electric vehicle platforms.
