Group14 Raises ~$169M Series D Extension for Spain Battery Plant

Group14 Technologies, the Woodinville, Washington-based maker of silicon battery materials, has closed a €150 million (about $169 million) Series D equity extension. The funding came from a new investor the company did not name, and no valuation was disclosed.

The extension brings Group14's total Series D round to more than $665 million. Securities.io reported that the original Series D closed on August 20, 2025, at $463 million, led by SK, Inc.

BAM-4 Brings SCC55 to Spain

As part of the deal, Group14 has committed to expanding its SCC55 production into Europe. The company selected Sagunto, Spain, for its next industrial-scale manufacturing module, BAM-4, with an initial capacity of 10 GWh.

"To truly transform the energy economy, battery material producers must be located where the batteries are made," said Rick Luebbe, CEO and co-founder of Group14 Technologies.

Luebbe said the Spain expansion reflects a strategy of building near key customer hubs and maintaining secure, localized supply chains, and that BAM-4 gives the company a springboard for Europe while it grows across the U.S. and Asia.

A 40 GWh Footprint Across Three Continents

Spain joins a network of battery active materials factories. BAM-1, a commercial-pilot facility in Woodinville that has operated since 2021, has delivered SCC55 to more than 150 customers. Two modules at BAM-2 in Moses Lake, Washington, totaling 20 GWh, are expected to start producing in 2027. One 10 GWh module at BAM-3 in Sangju, Korea, is operational and scaling.

Including BAM-4, Group14 puts its near-term manufacturing footprint at 40 GWh.

What SCC55 Does

Group14 describes itself as the world's leading manufacturer and supplier of advanced silicon battery materials. SCC55 is Group14's flagship silicon-carbon battery material. The company says it delivers higher energy density and faster charging and works with any battery chemistry. Group14 cites commercial traction in smartphones, drones, hypercars and eVTOL aircraft, and says its technology is backed by a global portfolio of more than 200 patents.

The Spain plant is meant to put that material closer to where European batteries are made.

Why It Matters

Battery materials have become a supply chain and geography question as much as a chemistry one. Group14's argument, stated plainly by Luebbe, is that materials producers have to sit next to the cell makers they supply, and this round is the money to act on that in Europe.

The structure is also notable. Rather than open a new lettered round, Group14 extended its Series D with a single unnamed investor and raised in euros, for a plant in Spain. It now has capacity planned or running in Washington state, South Korea and Spain. That spread lets the company pitch regional supply to automakers and electronics makers on each continent, a growing priority as buyers weigh trade and logistics risk.

For a U.S. company, the larger near-term volume still sits at home. The Moses Lake modules account for half of the 40 GWh target and are not slated to produce until 2027, so execution there will shape how quickly the expanded footprint becomes real output.
