New York – November 4, 2022 – AEA Investors’ Small Business Private Equity team announced today that its fund has closed the acquisition of Rees Scientific, Inc. alongside rollover investment from the Company’s employees. Established in 1982 and headquartered in Trenton, New Jersey, Rees is the largest provider of automated environmental monitoring solutions to the high-end life sciences market. Rees’ continuous environmental monitoring systems are integral to customers as they serve as a failsafe to protect the most sensitive and expensive (or in some cases, irreplaceable) assets within life sciences, including tissue samples, cell and gene therapy drugs, biologics, organs and blood.

Rees represents an exciting opportunity to invest in the large and growing life sciences instrumentation and measurement space, which has been an area of focus for AEA SBPE. The Company’s differentiated service network, industry leading product offering supported by proprietary software and long-term customer relationships with highly recurring revenue make Rees a highly attractive asset.
