Generac acquires North Dakota mobile heater manufacturer

Waukesha-based Generac Holdings Inc., a designer and manufacturer of generators and other small engine powered products, has acquired Bismarck, N.D.-based MAC Inc. and its related entities.

MAC is a leading manufacturer of premium-grade commercial and industrial mobile heaters in the U.S. and Canada. It has about 100 employees.

“The acquisition of MAC is an exciting development for Generac as it further expands our growing mobile products platform by adding a strong brand of industrial heaters and increases our access to the projected long term up-cycle in the oil and gas market,” said Aaron Jagdfeld, president and chief executive officer of Generac. “In addition to gaining immediate access to a broad lineup of mobile heating equipment that is essential to colder climate oil & gas and construction sites, this acquisition creates cross-selling opportunities with our existing mobile products distribution.”

The MAC management team will continue to lead the company, and the MAC product brand will be retained and will join Generac’s family of brands. The purchase agreements were executed and the transaction simultaneously closed last week. The purchase price and terms of the transaction were not announced.

“We’ve worked hard to build MAC into a great company, and we believe that partnering with Generac best positions our organization for continued growth,” said Michael Seifert, president and chief executive officer of MAC Inc. “We are excited to be joining the Generac team, and we see many synergies for both companies as a result of this transaction.”

MAC primarily serves the oil & gas and construction markets, as well as other industrial sectors through national equipment rental companies and independent dealers. MAC’s line of flameless, indirect-fired and hydronic surface heaters are recognized as some of the safest, most reliable and efficient machines in the market.
