Exhibit 99 MDU Resources Earnings Increase BISMARCK, ND - January 25, 2001 - MDU Resources Group, Inc. (NYSE:MDU) announced financial results for the year ended December 31, 2000, showing consolidated earnings of $110.3 million, or $1.80 per common share, diluted, compared to $83.3 million, or $1.52 per common share, diluted, for 1999. Revenues, which exceeded $1 billion for the first time in 1999, totaled nearly $1.9 billion, a 46 percent increase over those of a year ago. "Our 2000 results are outstanding and reflect our focused growth strategy and the diligent work of our employees," said Martin A. White, president and chief executive officer of MDU Resources. "Our company has changed dramatically in the past few years and these changes are obvious in our earnings. Only ten years ago, more than one-half of our earnings came from our utility business. Today approximately 20 percent of our earnings come from our electric and natural gas distribution businesses. The remainder of our earnings comes largely from the business lines that we have grown during the last decade, including the construction materials and mining, natural gas and oil production and utility services businesses. Unlike the utility, which now serves portions of five states in the northern Great Plains, collectively these nonutility segments do business throughout most of the United States. In addition to the outstanding financial performance our growth produced, a number of operational goals were also achieved, setting the stage for further growth." At the natural gas and oil production segment, earnings of $38.6 million were more than double when compared to 1999 earnings. Natural gas and oil production increased a combined 15 percent from a year ago, the result of aggressive drilling programs in existing fields and production from coal bed natural gas and other properties acquired in late 1999 and early 2000. In addition, significantly higher energy prices at the wellhead contributed to the earnings growth. Realized natural gas and oil prices averaged 50 percent higher for the year. Increased depreciation, depletion and amortization costs, as well as higher operating expenses due largely to acquisitions, somewhat offset the gains. At the construction materials and mining segment, earnings increased 47 percent to $30.1 million. The increase resulted from acquisitions made since the comparable period last year and record sales volumes of cement, aggregates and ready-mixed concrete. These results were partially offset by increased energy costs and higher interest expense. Depreciation, depletion and amortization and selling, general and administrative costs increased as well. Earnings from coal operations also increased largely due to the absence in 2000 of a $5.6 million after-tax charge to 1999's earnings, the result of the resolution of a coal arbitration proceeding. The previously announced sale of coal properties is still subject to various closing conditions. Electric earnings increased 11 percent to $17.7 million largely due to increased retail sales demand and continued strong wholesale electric sales at higher margins. These increases were partially offset by higher maintenance costs and depreciation expense. Earnings from the utility services segment totaled $8.6 million, an increase of 32 percent over last year. The improvement was the result of earnings from companies acquired since the comparable period last year as well as increased work loads in the Rocky Mountain region, primarily related to fiber optic projects, combined with increases in engineering services. The increases were somewhat offset by decreased construction activity for utilities on the West Coast. In early January 2001, the company acquired the Capital Electric construction companies, based in Kansas City, Missouri. This acquisition broadens the geographical scope of utility services and complements existing businesses. Earnings from the company's natural gas distribution segment increased from $3.2 million to $4.8 million. The increase was largely the result of higher retail sales due to weather in the fourth quarter which was 46 percent colder than a year ago. Earnings from the recently acquired Great Plains Natural Gas Co. and higher service and repair margins also contributed to the increase. These increases were somewhat offset by higher depreciation expense. The earnings at this segment did not benefit from high natural gas prices as gas costs are passed through at cost from producer to the end-use customer. Earnings at the pipeline and energy services segment of $10.5 million were half those of the comparable period last year. An asset impairment totaling $3.9 million after-tax at one of our energy services businesses contributed to the decreased earnings. Also contributing to the earnings decline were the effects of adjustments made to income in both 1999 and 2000 resulting from the resolution of outstanding regulatory and tax issues. The resolution in late 2000 of a 1995 general rate proceeding resulted in a credit to income of $6.7 million after-tax, $3.3 million less than similar credits to income in 1999. Lower operating margins from energy services and increased operation and maintenance expenses also contributed to the decline. Increased volumes transported by the pipeline at higher average rates and increased gathering revenues somewhat offset these declines.

Many of these highlighted points are "forward-looking statements." There is no assurance that the company's projections, including estimates for growth and increases in revenues and earnings, will in fact be achieved. Please refer to the various important factors listed at the end of this document under the heading "Safe Harbor for Forward- looking Statements" that could cause actual future results to differ materially from the company's targeted growth, revenue and earnings projections. MDU Resources Group, Inc. - - Based on our current expectations, the company anticipates that its three to five year compound annual earnings per share growth rate from operations will be in the general range of 10 to 12 percent. - - Earnings per share, diluted, from operations for 2001 are projected in the $1.95 to $2.05 range. - - The company expects the percentage of 2001 earnings per share from operations by quarter to be in the following approximate ranges: - First Quarter - 13 to 18 percent - Second Quarter - 20 to 25 percent - Third Quarter - 35 to 40 percent - Fourth Quarter - 22 to 27 percent - - The company expects to issue and sell equity from time to time to keep its debt at the nonregulated businesses at no more than 40 percent of total capitalization. - - The company invested over $529 million in growth and ongoing capital expenditures during 2000, using a combination of debt and equity sources, and internally generated funds. Of that total, over $285 million was for acquisitions. - - The company anticipates investing approximately $340 million in growth and ongoing capital expenditures during 2001, including potential future acquisitions. - - At December 31, 2000, the company had a goodwill balance of $91.4 million, net of accumulated amortization. Based on existing operations, annual goodwill amortization expense is expected to be approximately $4 million. Electric - - Owns or contracts for approximately 500 megawatts of electricity, owns and operates approximately 3,100 miles of transmission lines and over 4,000 miles of distribution lines. - - Set a peak record for on-system electric usage on August 11, 2000. This system peak demand of 432 megawatts was approximately a 3 percent increase over 1999's peak. - - Due to growing electric demand, a gas-fired 40-megawatt electric plant may be added in the three to five year planning horizon. Natural Gas Distribution - - Annual natural gas throughput for 2001 is expected to be approximately 56 million decatherms, with about 40 million decatherms from sales and 16 million from transportation. - - The number of natural gas retail customers at existing operations is expected to grow by approximately 1.5 to 2 percent on an annual basis over the next three to five years. - - Earnings are expected to increase from the growth in sales of new value-added products and services such as appliance repair contracts and home security systems. Utility Services - - Offers a full line of services to strengthen the nation's electric, gas and communications networks. - - Operations are divided into four regions covering the United States. Currently this segment is licensed to do business in 39 states. - - This segment is growing both internally and through acquisitions of utility services companies that are well managed, have excellent reputations and are growth-driven. - - Revenues for the utility services segment are expected to exceed $300 million in 2001. - - This business segment's goal is to achieve compound annual revenue and earnings growth rates of approximately 20 to 25 percent over the next five years. Pipeline and Energy Services - - This business segment's pipeline and storage services cover seven states in the Rocky Mountains and Upper Midwest. - - Two pipeline projects related to the company's coal bed natural gas drilling program in the Powder River Basin of Wyoming and Montana were completed in 2000. The two projects provide the pipeline company the ability to move approximately 40 percent more coal bed natural gas through its system than has historically been transported, as well as enabling additional deliveries to other pipeline systems. The largest project involved building a 75-mile, nonregulated pipeline through the heart of the basin, to move gas produced from throughout the Powder River Basin to interconnecting pipeline systems, including the company's own transmission system. - - In 2001, Williston Basin's natural gas throughput is expected to increase by approximately 9 percent. - - This segment continues business development activities looking for assets and resources that add value to existing operations through further vertical integration of its natural gas delivery and storage systems. Natural Gas and Oil Production - - During 2000, the company-operated portion of this segment's natural gas and oil production business drilled 291 developmental wells in the Powder River Basin of Wyoming and Montana and 75 developmental wells in our other operated properties located in Montana. Of the 366 wells drilled, 363 were successful. During the same time frame, the company's non-operated portion of this segment's natural gas and oil production business participated in drilling a total of 90 wells, of which 72 were successful. - - The 2001 drilling program is projected to include over 500 wells, 90 percent of which are expected to be drilled on operated properties and the emphasis will continue to be on natural gas. The 2001 drilling program is expected to be the single largest drilling program in our history. - - Combined natural gas and oil production in 2000 totaled 40.5 Bcf equivalents - a daily average of 111,000 Mcf equivalents. For the month of December, combined production averaged 128,300 Mcf equivalents per day, which was 22 percent higher than January 2000. - - Combined natural gas and oil production at this business segment is expected to be 30 to 40 percent higher in 2001 than in 2000. - - Proved natural gas and oil reserves at December 31, 2000, are over 400 Bcf equivalents, of which approximately 77 percent are natural gas. - - The company's estimates for natural gas prices in the Rocky Mountain region are in the range of $2.50 to $3.00 per Mcf during 2001. The company's estimates for natural gas prices on the NYMEX for 2001 are in the range of $3 to $4 per Mcf. - - The company's 2001 estimates for NYMEX crude oil prices are in the range of $23 to $26 per barrel. - - This business segment has entered into hedging arrangements for a portion of its 2001 production. The company has entered into swap agreements and fixed price forward sales representing approximately one-fourth of 2001 estimated annual natural gas production. Natural gas swap prices range from $4.57 to $4.60 per Mcf based on NYMEX and $4.04 to $4.44 per Mcf for Rocky Mountain gas sales. In addition, approximately one-third of 2001 estimated annual oil production is hedged at NYMEX prices ranging from $28.65 to $29.22 per barrel. Construction Materials and Mining - - At December 31, 2000, the construction materials and mining business estimates it had 890 million tons of economically recoverable aggregate reserves. These reserves are strategically located and represent more than a 40-year supply at current consumption levels. - - Excluding the effects of potential future acquisitions, aggregate, asphalt and ready-mixed concrete volumes are expected to increase by approximately 15 percent, 32 percent and 13 percent, respectively, in 2001. - - Since 1992, this business segment has grown from $45 million in annual revenues to $631 million in 2000. This segment expects to achieve compound annual revenue and earnings growth rates of approximately 10 to 20 percent over the next five years. - - Earnings are expected to increase from a combination of acquisitions and by optimizing both synergies and improvements at existing operations.
