Atlanta, GA

H-E Parts International, a global leader in the manufacturing,
servicing and marketing of aftermarket parts and components for mining, crushing and heavy construction
equipment, announces the acquisition of Mackay, Australia – based Dyno Power Pty. Ltd., one of Australia’s
leading independent high-horsepower diesel engine and transmission remanufacturers. From its state-of-the-art
facility, Dyno Power adds critical expertise, technologies and services to H-E Parts global aftermarket parts and
support offering.

“Dyno Power adds a critical product line to our Australian operations,” says Steve McBrayer, CEO of H-E Parts.
“Dyno is recognized for its commitment to quality and is a natural fit within H-E Parts. We are very proud to see
them joining our ranks. The addition of Dyno Power coupled with our recent acquisition of COR Cooling allows
H-E Parts to offer our Australian customers unrivaled rebuild and repair capabilities.”

H-E Parts will greatly benefit from Dyno Power’s Mackay facilities as well as their team of technicians and diesel
engine mechanics. “Joining H-E Parts will enable Dyno Power to deliver a broader product offering to our
expanding customer base in addition to bringing engine and transmission rebuilding capabilities to the H-E Parts
customers” says Paul Shackleton, former owner of Dyno Power.

Ian Olivieri, COO Australia for H-E Parts, says, “Our customers have been constantly asking H-E Parts for diesel
engine and transmission remanufacturing services”. The acquisition of Dyno Power will result in a significant
upgrade in the value we bring to our customers here in Australia and fits well with our Seattle based B&G
Machine Inc. engine rebuilding technology that the group acquired in 2013. The combination of our expanded
diesel technology, the recent acquisition of COR Cooling and our existing wheel end and suspension component
businesses, H-E Parts will now be able to offer a full dive line repair concept to our haul truck customers. H-E
Parts has become the only independent company offering such a comprehensive set of remanufactured solutions
to help miners lower operating costs and improve the performance of their fleet.”
