ProLogium

Founded in 2006, ProLogium Group is an energy innovation company focused on the research, development and manufacturing of next-generation lithium ceramic batteries. The Company holds more than 1,200 patents and patent applications worldwide, including granted patents and pending applications. In 2013, ProLogium successfully commercialized its solid-state battery technology, initially for use in smartphone charging accessories. Since 2013, the Company has delivered more than 2.4 million battery cells to partners and customers, including batteries used in in-vehicle audio systems, as well as approximately 10,000 automotive battery samples.

ProLogium has also built more than 13 years of manufacturing expertise and was among the first to successfully commercialize a high-efficiency roll-to-roll ceramic separator coating process. Its Taoke Gigafactory announced that it was the first commercial next-generation lithium ceramic battery gigafactory with a publicly demonstrated mass-production line, demonstrating that next-generation lithium ceramic batteries are no longer confined to the laboratory, but can be manufactured at scale as a commercially viable solution. ProLogium’s first GWh-scale gigafactory, the Taoke Gigafactory, is located in Taoyuan, Taiwan. In 2024, the Company established its first overseas R&D center in Paris-Saclay, France, providing customized technology support for the European market. Its second battery gigafactory, located in Dunkirk, France, held the groundbreaking ceremony for the first phase of construction in February 2026 and is now advancing through detailed design and construction. Upon completion of the first phase, the facility is designed to reach 4.0 GWh of annual designed production capacity, which is expected to be progressively achieved by 2030. The Dunkirk site has a maximum designed production capacity of up to 44.0 GWh and will work closely with ProLogium’s Paris-Saclay R&D center.

In May 2026, ProLogium entered into a definitive business combination agreement with Translational Development Acquisition Corp. (Nasdaq: TDAC) and has filed a registration statement on Form F-4 with the U.S. Securities and Exchange Commission. Under the current transaction structure, subject to completion of the business combination, receipt of applicable approvals and satisfaction of listing conditions, ProLogium is expected to list on Nasdaq under the proposed ticker symbol PRLG. For ProLogium, access to the U.S. public capital markets upon completion of the transaction represents more than a financing event; it is an important step in supporting the Company’s next phase of technology commercialization, global capacity expansion and industrial-scale development.
