MDU Resources Reports Second Quarter Earnings, Reaffirms 2018 Guidance
BISMARCK, N.D. — July 31, 2018 — MDU Resources Group, Inc. (NYSE: MDU) today reported second quarter earnings from continuing operations of $44.1 million, or 22 cents per share, compared to second quarter 2017 earnings from continuing operations of $43.8 million, or 22 cents per share. Including discontinued operations, MDU Resources reported second quarter earnings of $43.8 million, or 22 cents per share, compared to $40.6 million, or 21 cents per share, in 2017.
For the six months ended June 30, MDU Resources had earnings from continuing operations of $86.0 million, or 44 cents per share, compared to $79.3 million, or 40 cents per share, in 2017. Including discontinued operations, the company had earnings of $86.2 million, or 44 cents per share, compared to $77.8 million, or 40 cents per share, in 2017.
“We are pleased with our ongoing growth and solid operational execution,” said David L. Goodin, president and CEO of MDU Resources. “Our construction services business is experiencing an exceptional year, with to-date earnings nearly fifty percent higher than last year. We had a record combined backlog of $1.62 billion of work at our construction services and construction materials businesses at the end of the second quarter. We also recently announced our third construction materials acquisition of the year, and we continue to evaluate additional acquisition opportunities at both construction businesses.
“Our utility and pipeline businesses continue to successfully execute on several growth opportunities. Our two significant pipeline expansion projects underway this year are progressing on schedule and on budget, and we look forward to their completion later this year. With Bakken natural gas production at record levels, there is high demand for additional transportation capacity in the region. Construction also is progressing as expected on our wind farm expansion in southwestern North Dakota, with completion anticipated this fall, and on the 345-kilovolt transmission line partnership project from Ellendale, North Dakota, to Big Stone City, South Dakota. All our businesses are focused on growth, with significant opportunities ahead.”
Business Unit Highlights
Construction Materials and Services
The construction services business had earnings of $14.1 million in the second quarter, compared to $12.4 million for the same period in 2017. This business experienced tax benefits from the federal Tax Cuts and Jobs Act enacted in December. It also continued to see strong performance from its outside specialty contracting operations, including high demand for sales and rentals of the utility construction equipment it manufactures as well as electrical transmission, distribution and substation work. It also continues to perform a high volume of inside specialty contracting work, particularly for high-tech, health care and higher education customers. The construction services business had a record backlog of work at June 30 of $888 million, compared to $596 million in 2017.
Earnings at the construction materials business were $24.3 million in the second quarter, up from $21.2 million in the second quarter of 2017. The earnings increase reflects the benefits of federal tax reform. The company earlier this month announced that it acquired Molalla Redi-Mix and Rock Products Inc. south of Portland, Oregon, which is expected to be accretive to 2018 earnings. This acquisition follows two others this year, Teevin & Fischer Quarry LLC in northern Oregon acquired in April and Tri-City Paving Inc. in Little Falls,

Minnesota, acquired in June. The construction materials backlog of work at June 30 was $731 million, compared to $766 million in 2017.
Regulated Energy Delivery
The electric and natural gas utility earned $2.3 million in the second quarter, compared to $5.0 million in second quarter 2017. Electric sales volumes were approximately 5 percent higher compared to the same period last year, and natural gas sales volumes were approximately 2 percent higher. Earnings for the quarter reflect adjustments related to the Washington Utilities and Transportation Commission's recent decision on the company's natural gas rate case, including the effects of federal tax reform, as well as higher operating costs.
The pipeline and midstream business earned $5.7 million in the second quarter, up from $5.3 million in 2017. The company transported record volumes of natural gas through its system for the fourth consecutive quarter, partly due to completing two expansion projects in 2017 that increased capacity. Construction continues this summer on the 38-mile Valley Expansion project in eastern North Dakota and western Minnesota and the 13-mile Line Section 27 Expansion project in northwestern North Dakota. These projects, for which the company has customer commitments, are expected to add more than 200 million cubic feet per day of natural gas transportation capacity, bringing the company's total capacity to more than 1.8 billion cubic feet per day.
Guidance
MDU Resources reaffirmed that it expects earnings per share in the range of $1.25 to $1.45 in 2018, based on these assumptions:

• | Normal operating conditions and weather conditions, including precipitation and temperatures, across all service areas.

• | No significant acquisitions or divestitures.

• | Investing $672 million for capital projects.

• | Construction services revenues in the range of $1.45 billion to $1.60 billion and construction materials revenues in the range of $1.8 billion to $1.9 billion, with margins comparable to or slightly higher than 2017.

Corporate Strategy
MDU Resources’ strategy is to increase market share and profitability in its regulated energy delivery and construction materials and services businesses, while enhancing value through organic growth opportunities and strategic acquisitions of well-managed companies and properties. The company, on a consolidated basis, anticipates 5 to 8 percent long-term compound annual growth on earnings per share.

Non-GAAP Financial Measures
The company, in addition to presenting its earnings in conformity with GAAP, has provided non-GAAP financial measures of EBITDA by operating segment and EBITDA from continuing operations. The company believes that these non-GAAP financial measures are useful to investors in evaluating the company's financial performance and valuation, especially based on the diversity of the company's operations. The company's management uses the non-GAAP measures in conjunction with GAAP results when evaluating the company's operating results and calculating compensation packages.
The company presents EBITDA by operating segment and EBITDA from continuing operations on a consolidated basis in this press release. The company defines EBITDA as earnings attributable to the operating segment before interest, taxes, depreciation, depletion and amortization, and EBITDA from continuing operations as income from continuing operations before interest, taxes, depreciation, depletion and amortization. The company's management considers it a useful financial measure in evaluating the operating performance of the company as well as each operating segment due to the diverse operations performed at each segment. The company believes EBITDA and EBITDA from continuing operations are useful measures in providing meaningful information about operational efficiency compared to the company's peers by excluding the impacts of differences in tax jurisdictions and structures, debt levels and capital investment. The presentation of EBITDA and EBITDA from continuing operations also is provided for investment professionals who use such metrics in their analyses. The investment community often uses these metrics to assess the operating performance of a company’s business and to provide a consistent comparison of performance from period to period. Non-GAAP financial measures are not standardized; therefore, it may not be possible to compare such financial measures with other companies’ non-GAAP financial measures having the same or similar names. The presentation of this additional information is not meant to be considered a substitution for financial measures prepared in accordance with GAAP. The company strongly encourages investors to review the consolidated financial statements in their entirety and to not rely on any single financial measure.
The following table provides a reconciliation of consolidated GAAP earnings to EBITDA from continuing operations. The reconciliation for each operating segment's EBITDA is included with each operating segment's condensed income statement.

The earnings discussion that follows includes financial information prepared in accordance with GAAP, as well as another financial measure, adjusted gross margin, that is considered a non-GAAP financial measure as it relates to the company's electric and natural gas distribution segments. The presentation of adjusted gross margin is intended to be a helpful supplemental measure for investors’ understanding of the segments' operating performance. This non-GAAP measure should not be considered as an alternative to, or more meaningful than,
6

GAAP measures such as operating income (loss) or earnings (loss). The company's adjusted gross margin measure may not be comparable to other companies’ gross margin measures.
In addition to operating revenues and operating expenses, management also uses the non-GAAP measure of adjusted gross margin when evaluating the results of operations for the electric and natural gas distribution segments. Adjusted gross margin for the electric segment is calculated as operating revenue less cost of electric fuel and purchased power and certain taxes, other than income. Adjusted gross margin for the natural gas distribution segment is calculated as operating revenues less purchased natural gas sold and certain taxes, other than income. These taxes, other than income included as a reduction to adjusted gross margin relate to revenue taxes. These segments pass on to their customers the increases and decreases in the wholesale cost of power purchases, natural gas and other fuel supply costs in accordance with regulatory requirements. As such, the segments' revenues are directly impacted by the fluctuations in such commodities. Revenue taxes fluctuate with revenues as they are calculated as a percentage of revenues. Period over period, the segments' operating income (loss) is generally not impacted by the increase or decrease in revenues since the change is directly related to the increase or decrease in wholesale cost of power purchases, natural gas or other fuel supply costs, nor is it impacted by revenue taxes since it is a direct result of revenues. The company's management believes the adjusted gross margin is an adequate supplemental measure as these items are included in both operating revenues and operating expenses. The company's management also believes that adjusted gross margin and the remaining operating expenses that calculate operating income (loss) are useful in assessing the company's utility performance as management has the ability to influence control over the remaining operating expenses.
The electric segment's operating income was $13.0 million and $13.2 million for the three months ended June 30, 2018 and 2017, respectively. Operating income for the three months ended June 30, 2018 and 2017, is calculated as operating revenues of $78.5 million and $74.6 million, respectively, less operating expenses of $65.5 million and $61.4 million, respectively. For the three months ended June 30, 2018, operating income decreased by $200,000 due to higher operation and maintenance expense; depreciation, depletion and amortization expense; and higher electric fuel and purchase power costs in the quarter. Partially offsetting these higher costs were higher operating revenues driven by increased sales of 5 percent to all major customer classes offset in part by reserves against revenues in certain jurisdictions for anticipated refunds to customers of the lower income taxes due to the enactment of the TCJA. For the three months ended June 30, 2018 and 2017, the segment's operating income of $13.0 million and $13.2 million, respectively, is adjusted by adding back operation and maintenance expense of $31.1 million and $29.3 million, respectively; depreciation, depletion and amortization expense of $12.5 million and $11.4 million, respectively; and certain taxes, other than income of $3.7 million and $3.7 million, respectively, to calculate adjusted gross margin of $60.3 million and $57.6 million, respectively.
The electric segment's operating income was $31.2 million and $35.5 million for the six months ended June 30, 2018 and 2017, respectively. Operating income for the six months ended June 30, 2018 and 2017, is calculated as operating revenues of $165.9 million and $162.8 million, respectively, less operating expenses of $134.7 million and $127.3 million, respectively. For the six months ended June 30, 2018 and 2017, the segment's operating income of $31.2 million and $35.5 million, respectively, is adjusted by adding back operation and maintenance expense of $61.2 million and $57.9 million, respectively; depreciation, depletion and amortization expense of $25.1 million and $23.4 million, respectively; and certain taxes, other than income of $7.5 million and $7.0 million, respectively, to calculate adjusted gross margin of $125.0 million and $123.8 million, respectively.
The natural gas distribution segment's operating income (loss) was $(4.4) million and $900,000 for the three months ended June 30, 2018 and 2017, respectively. Operating income (loss) for the three months ended June 30, 2018 and 2017, is calculated as operating revenues of $129.5 million and $131.6 million, respectively, less operating expenses of $133.9 million and $130.7 million, respectively. For the three months ended June 30, 2018, operating income decreased by $5.3 million due to higher operation and maintenance expense, which includes a non-recurring expense related to the recently approved WUTC general rate case settlement; lower operating revenues largely resulting from reserves against revenues in certain jurisdictions for anticipated refunds to customers due to the enactment of the TCJA and lower purchased natural gas sold passed through to customers; and higher depreciation, depletion and amortization expense. For the three months ended June 30, 2018 and 2017, the segment's operating income (loss) of $(4.4) million and $900,000, respectively, is adjusted by adding back operation and maintenance expense of $42.5 million and $39.0 million, respectively; depreciation, depletion
7

and amortization expense of $17.7 million and $17.2 million, respectively; and certain taxes, other than income of $5.4 million and $5.1 million, respectively, to calculate adjusted gross margin of $61.2 million and $62.2 million, respectively.
The natural gas distribution segment's operating income was $44.2 million and $52.3 million for the six months ended June 30, 2018 and 2017, respectively. Operating income for the six months ended June 30, 2018 and 2017, is calculated as operating revenues of $462.2 million and $474.1 million, respectively, less operating expenses of $418.0 million and $421.8 million, respectively. For the six months ended June 30, 2018 and 2017, the segment's operating income of $44.2 million and $52.3 million, respectively, is adjusted by adding back operation and maintenance expense of $87.2 million and $80.0 million, respectively; depreciation, depletion and amortization expense of $35.4 million and $34.2 million, respectively; and certain taxes, other than income of $11.2 million and $10.2 million, respectively, to calculate adjusted gross margin of $178.0 million and $176.7 million, respectively.

The electric business reported earnings of $9.1 million in the second quarter of 2018, compared to $7.8 million for the same period in 2017. The increase in earnings reflects higher electric adjusted gross margins resulting from 5 percent higher retail sales volumes to all major customer classes. Partially offsetting the increase was higher operation and maintenance expense, largely from increased contract services and payroll-related costs, as well as higher depreciation, depletion and amortization expense.
The electric business's EBITDA increased $1.7 million in the second quarter of 2018, compared to 2017, primarily the result of higher electric retail sales margins offset in part by higher operation and maintenance expense, as previously discussed.

The natural gas distribution business reported a seasonal loss of $6.8 million in the second quarter of 2018, compared to a seasonal loss of $2.8 million for the same period in 2017. The decrease in earnings was driven by increased operation and maintenance expense reflecting certain adjustments related to the recent WUTC general rate case decision, including the effects of federal tax reform, and higher payroll-related costs. Also contributing to the decrease was higher depreciation, depletion and amortization expense due to increased plant additions.
The natural gas distribution business's EBITDA decreased $4.3 million in the second quarter 2018, compared to 2017, primarily the result of higher operation and maintenance expense.

The pipeline and midstream business reported earnings of $5.7 million in the second quarter of 2018, compared to $5.3 million in 2017. The increase reflects lower income taxes due to the enactment of the TCJA and higher nonregulated project revenues. Increased transportation revenues and volumes from new projects were more than offset by decreased storage related revenue and higher depreciation, depletion and amortization expense. Also offsetting the increase was higher operation and maintenance expense largely resulting from increased nonregulated project costs.
The pipeline and midstream business's EBITDA decreased $400,000 in the second quarter of 2018, compared to 2017, primarily from higher operation and maintenance expense, partially offset by higher nonregulated project revenues.

The construction services business reported earnings of $14.1 million in the second quarter of 2018, compared to $12.4 million for the same period in 2017. The increase in earnings was the result of lower income tax expense due to the enactment of the TCJA. Higher gross margins were the result of increased outside specialty contracting workloads, driven by customer demand for outside equipment sales and rentals, partially offset by lower inside specialty contracting workloads. Offsetting the increase in gross margins was higher selling, general and administrative expense, primarily from payroll-related costs, which resulted in a decrease to operating income.
The construction services business's EBITDA decreased $1.2 million in the second quarter of 2018, compared to 2017, as a result of higher selling, general and administrative expense.
