Amprius Recognized by TIME as One of America's Top GreenTech Companies for 2026

Amprius was honored by TIME and Statista as one of America's Top GreenTech Companies 2026, recognizing its overall innovation, environmental impact, and financial strength. The Company is among the top 250 companies selected from more than 3,500 evaluated worldwide, reflecting its continued growth and expansion across commercial applications as demand increases in its core markets, including aviation, defense, and advanced mobility.

"This recognition from TIME is meaningful because it brings together companies that are not just developing new technologies, but actually improving how energy is used and delivered," said Tom Stepien, CEO of Amprius. "At Amprius, we are laser-focused on creating batteries that push performance while also reducing the energy required to operate them. That combination is what drives real sustainability-focused progress, and we are proud to be included in this group."

The Company's inclusion in TIME's Top GreenTech Companies reflects its continued progress across innovation and commercial execution. Amprius' strong Q4 and full-year 2025 fiscal results demonstrated robust revenue growth, improving margins, and rising demand across its core markets. The Company also recently announced its first U.S.-based manufacturing partner, marking a significant milestone in expanding capacity and strengthening its domestic supply chain, further positioning Amprius as a leader in sustainable energy solutions.

Amprius continues to advance high-performance energy solutions that improve efficiency and reduce energy intensity. This approach was also recognized at the CES Innovation Awards in January of this year. Together, these developments reflect the combination of innovation, climate-focused impact, and growing market adoption that define Amprius' selection in this year's Top GreenTech Companies.
