Aspen Aerogels Wins General Motors’ 2025 Supplier of the Year for EV Thermal Tech

Aspen Aerogels, Inc. (NYSE: ASPN) said it has been named General Motors’ 2025 Supplier of the Year, a distinction presented as part of GM’s 34th annual Supplier of the Year awards. The company tied the recognition to what it calls its contribution to GM’s electric-vehicle thermal management strategy, an area aimed at keeping batteries and power electronics within safe operating temperatures.

In its announcement, Aspen described aerogel-based materials as engineered insulation designed to address thermal runaway challenges in the EV market. Aerogel, in general terms, is an extremely lightweight solid material with strong insulating properties, and it is used in vehicle systems where heat control can affect performance and safety.

Aspen’s President and Chief Executive Officer Don Young said the award adds to an “Overdrive Award” Aspen previously received from GM, framing the new honor as recognition of an ongoing working relationship with the automaker and “the dedication” of the Aspen team. He also linked the company’s work to advancing battery performance as automakers accelerate electrification.

GM’s purchasing and supply chain leadership also commented in the announcement. GM’s Shilpan Amin, senior vice president and the automaker’s global chief procurement and supply chain officer, said Supplier of the Year highlights partnerships across the product development cycle and that suppliers that “lean in” on new technology and execution help GM move faster and deliver vehicles aligned with customer needs.

The supplier award program described by Aspen recognizes 103 suppliers across 14 countries. GM’s selection process, as outlined in the company’s release, weighs performance in areas including safety, innovation, execution, resilience, customer support, and alignment to GM’s strategic priorities. Aspen said the program also distinguishes suppliers that exceed expectations with an Overdrive Award.

The announcement positions Aspen as a materials technology company focused on sustainability and electrification solutions. On its investor relations site, Aspen says its aerogel technology is built around an “Aerogel Technology Platform” and that its installed base of aerogel materials is more than $1 billion, with a global intellectual property portfolio. The company also states that it supports electric vehicle adoption and energy efficiency through its products and engineering solutions.

What remains unclear is how the Supplier of the Year award specifically maps to particular GM vehicle programs, plant sites, or contract values. Aspen did not disclose the size of any related GM agreement, the exact product lines used on specific models, or whether the award is tied to new business in 2025 versus performance on existing supply. For investors and industry watchers, the next step would be to watch for more granular details in Aspen’s subsequent earnings materials and in any GM disclosures around its sourcing strategies.
