USBC, Inc. divested its legacy non-invasive sensor technology business to Particle Acquisition Corporation, an entity controlled by former Chairman and CEO Ronald P. Erickson. The transaction closed on March 27, 2026, for a nominal cash consideration of $1.00 plus the assumption of all related business liabilities, including a Seattle office lease. USBC retains a 10% revenue share on future net revenue from covered products for up to five years post-first commercial sale. The company will receive an acquisition share payment ranging from 5% to 35% if the buyer is acquired within five years. USBC provided a short-term secured promissory note of up to $450,000 to fund the buyer's operating expenses. The divestiture is not expected to have a material financial impact on USBC's financial statements.
