ProLogium to List in $3.8 Billion SPAC Deal

The deal secures capital to scale fourth‑generation solid‑state battery production, finance a Dunkirk gigafactory, and target EVs plus adjacent markets including data centers, aerospace, robotics, defense.

Overview

  • ProLogium announced Wednesday that it will merge with Translational Development Acquisition Corp in a $3.8 billion SPAC transaction that will list the combined company on Nasdaq under the ticker PRLG.
  • The companies expect the merger to close in the second half of 2026 and have named Cohen & Company Markets, BTIG and Crédit Agricole CIB as advisers and placement agent.
  • ProLogium said the funds will be used to scale its fourth‑generation lithium‑ceramic solid‑state batteries and to build a new gigafactory in Dunkirk, France, with construction slated to begin later in 2026 and mass production targeted for the second quarter of 2029.
  • The firm, founded in 2006 and a pioneer in solid‑state cells, has shipped over 2.4 million cells since 2013 and says the technology offers higher energy density and improved safety compared with conventional lithium‑ion cells.
  • If executed, the plan could onshore advanced battery manufacturing in Europe, create local factory jobs and give ProLogium capital to push into non‑automotive markets such as data centers, aerospace, robotics and defense.
