Dual-listed Eroad, which specialises in GPS fleet-tracking systems, said it had gone into a trading halt while it raised funds to buy Auckland-based Coretex, for $157.7m.
The deal involves an additional payment of $30.6m, contingent on Coretex meeting certain performance milestones.
Eroad said it was conducting an underwritten conditional placement to raise $64.4m and a share purchase plan to raise $16.1m to partly fund the purchase.
Coretex has connected units in North America, Australia and New Zealand, with a focus on less than a truck load (LTL), refrigerated transport, construction, and waste and recycling.
