ProLogium Technology Announces $3.8 Billion Nasdaq Listing Via SPAC to Fund Solid-State Gigafactory in France

Taiwan-based solid-state battery developer ProLogium Technology announced on May 27, 2026 a merger with Translational Development Acquisition Corp (TDAC) to list on the Nasdaq under ticker PRLG, in a transaction valuing the combined company at approximately $3.8 billion. ProLogium is one of the few solid-state battery companies globally to have demonstrated any form of mass-production line — it claims to be the only company with a proven solid-state battery mass-production process — and its 4th-generation LMB (lithium-metal battery) cells achieved 360 Wh/kg in third-party testing. Proceeds from the SPAC listing will fund ProLogium's primary strategic asset: a gigafactory in Dunkirk, northern France, backed by €1.5 billion in combined French government and EU regional funding. The Dunkirk facility targets mass production ramp in Q2 2029 and is designed to supply European OEMs, positioning ProLogium as a potential European-based solid-state cell supplier — distinct from Asian manufacturers building in Europe. In addition to automotive applications, ProLogium is marketing its cells to data centers (where high energy density reduces rack space and UPS footprint), aerospace (eVTOL, drones), and humanoid robotics. The $3.8 billion valuation reflects significant premium over ProLogium's production capacity and revenue, consistent with the sector-wide bet that solid-state is the next dominant automotive battery chemistry. The SPAC route — chosen over a traditional IPO — allows ProLogium to present forward-looking financial projections to investors, a mechanism that facilitated previous high-profile battery IPOs (QuantumScape via Klein, Solid Power via DCRC). The Nasdaq listing would make ProLogium the second solid-state battery company publicly traded on a major US exchange after QuantumScape (QS).
