"Celebrating 100 years is a remarkable milestone, made possible by our team of talented employees — past and present — and we're excited to share our story with analysts, investors, stakeholders and customers," Kivisto said. "We are proud of what we've accomplished in our first century and are excited about the next 100 years."

About MDU Resources' 100 years
MDU Resources was incorporated on March 14, 1924, as a small utility serving rural communities along the Montana-North Dakota border. Over the past century, MDU Resources has grown into a corporation with operations across the United States.

Today, MDU Resources' utility operations serve nearly 1.2 million electric and natural gas customers across eight states. Its pipeline business has approximately 3,800 miles of regulated natural gas transmission lines and is home to the largest underground natural gas storage field in North America.

The company's success includes growing two businesses to be large enough to be spun off to stand on their own as publicly traded companies.

MDU Resources' construction materials subsidiary, Knife River Corporation, was spun off in 2023. MDU Resources' construction services subsidiary, MDU Construction Services Group, is expected to be spun off in late 2024.

While MDU Resources branched out into other industries, it has throughout its history remained committed to its core business of regulated energy delivery.

"The company has seen a lot of changes over the past 100 years, but our commitment to safely and reliably serving our customers and communities has remained constant," Kivisto said. 

Analyst and Investor Day
MDU Resources will host an Analyst and Investor Day at 10 a.m. EDT March 13 at the NYSE. During the event, executive management will provide updates on operational strategy, the corporation's financial outlook, and the expected tax-free spinoff of MDU Construction Services Group.

MDU Resources' 100th anniversary celebration will continue throughout 2024, and additional information can be found at Among the celebratory events, the MDU Resources Foundation, MDU Resources' philanthropic arm, will donate $10,000 each to 10 charities nominated by its employees.
