Amprius Technologies Appoints Ricardo C. Rodriguez as Chief Financial Officer

Amprius Technologies, Inc. (“Amprius” or the “Company”) (NYSE: AMPX), a leader in next-generation lithium-ion batteries with its Silicon Anode Platform, announced the appointment of Ricardo C. Rodriguez as Chief Financial Officer (CFO), effective immediately. As part of a planned transition and as previously disclosed, prior Company CFO Sandra Wallach is retiring and will support the Company in the short term.

Rodriguez brings more than two decades of leadership experience in finance, strategy, and operations across the automotive, mobility, and broader technology sectors. He most recently served as CFO and Treasurer of Aspen Aerogels (“Aspen”) (NYSE: ASPN), where he guided the company through a critical growth phase that included raising significant growth capital, expanding operations, and strengthening Aspen’s positioning as a leading electrification materials provider. Prior to that, he was Aspen’s Chief Strategy Officer, playing a central role in commercial expansion and long-term strategic planning.

“Ricardo is a proven financial and strategic leader with deep expertise in electrification and advanced technologies,” said Dr. Kang Sun, CEO of Amprius Technologies. “His proven track record of driving growth with financial discipline in high-performance markets will serve as a valuable guide as we expand our commercial reach, scale global manufacturing, and reinforce Amprius’ leadership in advanced battery technology.”

“I would also like to publicly thank Sandra Wallach for her service to Amprius over the last several years. Sandra’s contributions to our Company are many, including playing a pivotal role in our successful transition to becoming a public company as well as her ongoing dedication in acting as a true steward of capital for Amprius. We wish her all the best in well-deserved retirement.”

Rodriguez added: “I am honored to join this Company at such a pivotal inflection point in its journey. Amprius is at the forefront of redefining what is possible in electrification with its silicon anode technology. I greatly appreciate the opportunity to help advance our strategy and expand this breakthrough platform, powering the future of aviation, defense, and advanced mobility. I look forward to working closely with our finance and leadership teams as well as our global partners to build on Amprius’ momentum as we continue to efficiently scale our operations.”

Earlier in his career, Rodriguez was Corporate Strategy Director at Aptiv (NYSE: APTV), where he launched and built the company’s Vehicle Electrification Systems group. He also held senior roles at ClearMotion, GM’s OnStar division; Amazon; and Fiat Chrysler Automobiles (now Stellantis). He began his career in investment banking at Lazard, where he focused on automotive mergers and acquisitions and restructuring.

Rodriguez earned a BS in Mechanical Engineering from General Motors Institute/Kettering University and an MBA from Harvard Business School.
