The deal represents Caribou's third acquisition for Resonetics in precision micro-manufacturing over the past year, following investments in Medelec and STI Laser. Caribou also grows Resonetics in the medical devices sector. "Consistent with our initial investment thesis for Resonetics, the Caribou acquisition strategically enhances the company’s capabilities, geographic reach and customer portfolio," says Resonetics CEO Chip Hance. "We believe that the recent acquisitions combined with the company’s strong organic growth have established Resonetics as a leading supplier of specialized componentry for interventional medical device companies.” GTCR invested in Resonetics in 2018. Kirkland & Ellis and PwC advised GTCR.
