Allison Transmission Holdings Inc. saw profits rise 57 percent, to $58 million, in the first quarter, the Indianapolis-based manufacturer announced Monday.
The earnings announcement was Allison’s first since it raised $600 million in a March initial public offering.
Revenue for the quarter was $602 million, up 16 percent from the same quarter a year ago. Sales were driven by a stronger North American truck market and increased demand around the world for commercial vehicles, both on-highway and off-highway uses, the company said.
Growth in Allison’s largest market segment, North American on-highway, drove sales up 34 percent, from $164 million a year ago to $219 million.
The truck market helped offset declines in military-related sales and in hybrid transit buses.
Allison shares fell 31 cents early Tuesday morning, to $21.59 each. The shares are down about 7 percent since the IPO.
