SANTA CLARA, Calif., and HOLLAND, Mich., Oct. 30, 2025 /PRNewswire/ — In an assignment for the benefit of creditors, Tiger Group today announced a major two-day online auction (Nov. 12-13) of assets from sodium-ion battery manufacturer Natron Energy.
The assets, many of which are either new or minimally used, were originally valued at approximately $74 million. They come from Natron Energy’s closed R&D and processing facility in Santa Clara, California, and sodium-ion manufacturing plant in Holland, Michigan. Taken together, the two buildings comprise more than 250,000 square feet.
“Tiger is pleased to have been selected to perform the liquidation of prominent manufacturer Natron Energy, which changed the way the world looks at critical power and industrial batteries for high-powered applications like AI, data centers, peak shaving and power-quality management,” said Tiger Group Senior Director of Business Development Jonathan Holiday. “The availability of this immaculate equipment is a rare opportunity.”
