RMA Companies has acquired A.J. Edmond Company, a provider of inspection, sampling, and analytical services.
A.J. Edmond provides inspection, sampling, and laboratory testing for producers and resellers of solid fuels and petroleum byproducts. The company specializes in the analysis of raw materials such as petroleum coke, coal, biomass, anodes, cathodes, carbon, sulfur, and iron ore.
A.J. Edmond was founded in 1965 and today operates out of three laboratory facilities near Los Angeles in Long Beach, California (headquarters); near San Francisco in Concord, California; and near Portland in Longview, Washington.
RMA Companies is a national provider of testing, inspection, certification, and compliance (TICC) services to the transportation, healthcare, power, and water end markets. Specific areas of expertise include environmental consulting, geotechnical engineering, geophysics and subsurface imaging, and pavement engineering.

RMA, founded in 1962, has approximately 700 employees – engineers, geologists, inspectors, and technicians – and is headquartered in Rancho Cucamonga, California.
The acquisition of A.J. Edmond is RMA’s seventh acquisition since being formed by OceanSound in September 2021. The six earlier acquisitions were Arizona-based Western Technologies (December 2021), California-based CSI Services (February 2022), Oregon-based Northwest Geotech (December 2022), California-based C Below (January 2023), Washington-based GeoTest Services (February 2023), and, just last week, Florida-headquartered PRI (March 2023).
“A.J. Edmond is one of the leading providers of mechanical sampling and analytical testing services for petroleum and solid fuel byproducts,” said Ed Lyon, the CEO of RMA. Their strategic positioning in ports and refineries adds new clients in the petrochemical industry to supplement our range of laboratory testing services for critical infrastructure end-markets, following our previous acquisition of PRI. We look forward to providing these services and driving cross-sell opportunities across the RMA companies.”
New York City-based OceanSound makes control investments of $75 million to $300 million in North America-based technology and technology-enabled services companies serving the government and enterprise industries. Typical target companies will have enterprise values of $150 million to $750 million. The firm is led by Managing Partner and Co-Founder Joe Benavides alongside fellow Partners and Co-Founders Ted Coons and Jeff Kelly.
In February 2022, OceanSound closed its debut fund, OceanSound Partners Fund LP, with an above-target $780 million of committed capital.
