Translational Development Acquisition Corp. Ordinary Shares

Mercedes-Benz AG and ProLogium Holding Inc. have signed a joint testing agreement giving Mercedes-Benz priority access to ProLogium's latest Gen4 Superfluidized Inorganic Next-Generation Lithium Ceramic Battery cells. Under the agreement, the Gen4 technology will undergo extensive electrical, thermal and safety testing at Mercedes-Benz's dedicated facilities and specialized external testing institutes, with results used to assess its suitability for potential use in future vehicles. The Gen4 platform aims to combine five core advantages: intrinsic safety, high performance, high energy density, scalable manufacturing and competitive cost structure, with a safety architecture integrating a non-flammable inorganic electrolyte, ceramic separator technology and ProLogium's proprietary active safety mechanism. The deal builds on a partnership of nearly ten years, during which Mercedes-Benz became a strategic investor in ProLogium and holds a Director on its Board, and follows ProLogium's May 2026 definitive business combination agreement with Translational Development Acquisition Corp. under which it is expected to list on Nasdaq under the proposed ticker symbol PRLG. ProLogium's Taoke Gigafactory in Taiwan has completed GWh-scale manufacturing validation, while its planned Dunkirk Gigafactory in France, which broke ground on its first phase in February 2026, is designed to reach 4.0 GWh of annual capacity in phase one and up to 44.0 GWh at full build-out.
