FREMONT, Calif. and WESTBURY, N.Y., May 12, 2022 /PRNewswire/ -- Amprius Technologies, Inc. ("Amprius"), the leader in lithium-ion batteries with its Si Nanowire Anode Platform, and Kensington Capital Acquisition Corp. IV ("Kensington") (NYSE: KCAC.U), a special purpose acquisition company, today announced a definitive agreement for a business combination that would result in Amprius becoming a publicly-listed company. Upon closing of the transaction, the combined company will be named Amprius Technologies, Inc. and its common stock will trade on the NYSE under the new ticker symbol "AMPX."

Founded in 2008, Amprius develops, manufactures, and sells ultra-high energy density lithium-ion batteries using its innovative, patent-protected silicon nanowire anode technology. Amprius batteries offer highest energy density for longer endurance and higher performance when compared to lithium-ion batteries that utilize graphite anodes. 

The market-leading performance of Amprius' 100% silicon anode battery is expected to accelerate the development of electric mobility, with the goal of making Amprius silicon nanowire anode technology a mainstream technology in the lithium-ion battery industry. Amprius batteries' high-energy and high-power capabilities are uniquely positioned to address the aviation, defense and electric vehicle markets. Amprius is currently delivering commercial batteries to the aviation and defense markets, with customers that include Airbus and AeroVironment. Having reached commercialization in the aviation and defense markets, Amprius is primed to make significant advancements, including, at the appropriate time, accessing additional markets including the automotive industry.

Dr. Kang Sun, Chief Executive Officer of Amprius, commented: "Today represents a significant milestone for Amprius. A merger with Kensington – who has extensive expertise and operating capabilities in the automotive and electric mobility sectors – will help us realize the full potential of our industry-disrupting technology. The superior performance of our silicon nanowire anode battery is unmatched in the commercial market. We believe Amprius will help power the mobility revolution and that the proceeds from this transaction, along with the partnership and support of Kensington's world-class team, will enable us to significantly scale our production capabilities to meet the overwhelming demand for our silicon nanowire anode batteries." 

Justin Mirro, Chairman and Chief Executive Officer of Kensington, added: "We are so impressed with Amprius and extremely pleased to announce our business combination with this great company. Amprius is already the market leader, and we are excited about combining their proven technology and commercialization with our manufacturing and public market experience to help the company meet demand. Amprius is truly advancing electric mobility today, and we are thrilled to support them in making the world better for generations to come."

Transaction Overview
The business combination values Amprius at an implied pro forma enterprise value of $939 million, assuming no redemptions by our public stockholders in connection with closing and the payment of estimated transaction expenses. The boards of directors of both Kensington and Amprius have approved the proposed transaction, which is expected to be completed in the second half of 2022, subject to, among other things, the approval by Kensington's stockholders and satisfaction or waiver of other conditions stated in the definitive documentation.
