Redwood Materials has laid off around 135 employees, or roughly 10% of its workforce, as it restructures to better accommodate its growing energy storage business, TechCrunch has learned.

The cuts come just five months after Redwood cut 5% of its workforce, and three months after it closed a $425 million funding round that boosted the battery-recycling company’s valuation to north of $6 billion, as TechCrunch previously reported.

It’s been a difficult time in the battery industry lately. Earlier this month, battery recycler Ascend Elements filed for Chapter 11 bankruptcy protection, citing “insurmountable” financial challenges. Some battery makers have also restructured or gone out of business as the automotive industry in the U.S. has backed away from its most optimistic and ambitious plans to transition to electric vehicles.

But Redwood Materials founder and CEO JB Straubel told employees that this fresh round of cuts is not a sign that the corporation is heading down the same path.

“Redwood today is the strongest it’s ever been,” Straubel wrote in an email to the workers who weren’t laid off, according to a copy viewed by TechCrunch. “The materials business is well on its way to profitability and has an exciting roadmap ahead.”

Straubel noted that Redwood “continue[s] to dominate the US battery recycling market” but also touted the company’s “great momentum” in its updated energy storage business. Redwood has recently proclaimed deals with Crusoe AI and, most recently, electric automaker Rivian to provide recycled batteries that can be used to power those companies’ facilities. The organization declined to comment beyond the contents of Straubel’s email.

In his message, Straubel wrote that “parts of the business have expanded faster than needed to support the direction” of Redwood. As a result, he stated Redwood is making cuts across multiple divisions, including the engineering and operations organizations, according to an employee who was granted anonymity to discuss the layoffs.

“We are confident that we can deliver on our critical projects with a smaller team that is more focused,” he wrote. “We have successfully adapted to changes in the economy that have bankrupted many of our competitors.” This also touches on aspects of user interface.

Straubel went on to write that he is “more excited than ever with our path ahead as we build the most integrated and cost-effective critical materials and energy storage business in the world.”

“This is a self-sustaining business and will continue to build this corporation more valuable over time. We have the team and the innovation to do what no other firm can,” he wrote.

Workers who were laid off were told by Redwood’s chief HR officer that the layoffs were made “to sharpen our focus, our work and the size of our teams to support the direction Redwood is going in the future,” which was viewed by TechCrunch.

Employees who were laid off are receiving severance and paid health benefits, according to Straubel, according to a copy of her email’s email, as well as “career transition assistance.”

“I am grateful to the approximately 135 employees who we say goodbye to today — they’ve all contributed to building Redwood,” he wrote.
