QuantumScape (NYSE:QS) used its fourth-quarter and full-year 2025 earnings call to highlight progress on its solid-state battery commercialization roadmap, emphasizing the rollout of its Cobra manufacturing process, pilot-line buildout for QSE-5 cells, and expansion of its partner and customer base. Management also provided 2026 guidance for adjusted EBITDA loss and capital spending while reiterating a 'capital-light' licensing strategy.

Why it matters

QuantumScape's solid-state battery technology has the potential to significantly improve electric vehicle performance and charging times, addressing key barriers to widespread EV adoption. The company's progress in scaling up manufacturing and securing partnerships with major automakers is closely watched by the industry as it works toward commercialization.

The details

Key 2025 milestones included baselining the Cobra manufacturing process, shipping Cobra-based QSE-5 cells to Volkswagen, and expanding commercial engagements with two additional global automotive OEMs. The company also added Murata Manufacturing and Corning as partners in its manufacturing ecosystem. In 2026, QuantumScape aims to demonstrate scalable production on its Eagle pilot line, advance automotive commercialization, and explore new markets beyond electric vehicles.

  • In June 2025, QuantumScape integrated its 'breakthrough Cobra process' into its cell production baseline.
  • In September 2025, the Ducati V21L race bike powered by QSE-5 cells made its debut at IAA Mobility in Munich.
  • On February 4, 2026, QuantumScape held an inauguration event for its Eagle pilot production line.
