ALERT: MDU Resources Group to Spin-Off Knife River
On August 4, 2022, before the market open, MDU Resources Group Inc. (NYSE: MDU) announced that the company plans to separate its aggregates-based, vertically integrated construction materials and contracting provider, Knife River Corp., into a standalone, publicly traded company via a tax-free spin-off. The separation is expected to be completed in 2023. The completion of the spin-off is subject to customary closing conditions such as final Board approval, an effectiveness declaration of the company’s Form 10 filing by the SEC, and a likely a private letter ruling regarding the tax-free status of the separation.
MDU, as it currently stands, operates two main businesses: Regulated Energy Delivery, and Construction Materials and Services. The company generated $5.7 billion in revenue and $860 million in EBITDA from continuing operations in 2021. Within the two businesses, MDU reports under five distinct segments: Electric, Natural Gas Distribution, Pipeline, Construction Materials and Contracting, and Construction Services.
Electric provides retail electric service to residential, commercial, industrial, and municipal customers located in Montana, North Dakota, Wyoming, and South Dakota via 15 electric generating units. The segment generated $349 million in revenue (6.1% of total revenue) and $66.3 million in operating income (12.3% of consolidate operating income) in 2021.
Natural Gas Distribution sells retail natural gas to residential, commercial, and industrial customers across eight north west and northern plains states including Washington, Oregon, Idaho, Montana, Wyoming, North and South Dakota, and Minnesota. The segment generated $971.4 million in revenue (17.1% of total revenue) and $89.2 million in operating income (16.5% of consolidate operating income) in 2021.
Pipeline owns and operates regulated and non-regulated pipelines and interconnecting pipelines across Montana, Wyoming, North and South Dakota, and Minnesota, as well as underground storage facilities. The segment generated $82.9 million in revenue (1.5% of total revenue) and $48.1 million in operating income (8.9% of consolidate operating income) in 2021.
Construction Materials and Contracting, operating as Knife River, mines, processes, and sells aggregates, such as crushed stone, sand, and gravel, used in construction. Additionally, the company produces and sells asphalt mix and ready-mix concrete. Knife River operates in 13 states, most of which MDU operates its regulated energy business in, as well as Alaska, California, and Texas. The segment generated $2.2 billion in revenue (39.2% of total revenue) and $191.1 million in operating income (35.4% of consolidate operating income) in 2021.
Construction Services operates in over 40 states and provides “a full spectrum of construction services through its electrical and mechanical and transmission and distribution specialty contracting services across the country.” Services are provided to a range of customers including utilities, manufacturing, transportation, and governments, amongst others. Services include construction and maintenance of electrical and communication wiring infrastructure, fire suppression systems, and overhead and underground electrical, gas and communications infrastructure. The segment generated $2.1 billion in revenue (36.1% of total revenue) and $145.8 million in operating income (27% of consolidate operating income) in 2021.
PRELIMINARY VALUATION
MDU currently trades at 8.7x its consensus 2023 EBITDA estimate. Following the separation, Knife River could more aptly be compared to cement and aggregate peer such as Vulcan Materials Co. (NYSE: VMC) and Martin Marietta Materials Inc. (NYSE: MLM), which each trade at 13.6x their respective 2023 EBITDA consensus The parent company will more apply be compared to regional electric and gas utilities, which trade at approximately 12x the average 2023 consensus estimate, transmission and distribution peers that trade at approximately 10.7x their 2023 consensus EBITDA estimate, and infrastructure construction peers, which trade in a wide range of 6x – 25x, yet on average trade at 13.2x.
On managements conference call, it was noted that the company expects the parent company to see revenue growth in the 5%-8% annual range on average moving forward, driven by increased rate base and growth in the customer base. Growth expectations for the spin company were not disclosed. Assuming modest growth of 2% at Knife River, and stable operating margins of 9.0% (roughly the average over the past three years), when incorporating historical depreciation and amortization, we estimate that the spin company would generate $314 million in EBITDA in 2023. Assuming 5% annual revenue growth for the parent company, and 9.5% operating margin (in line with 2021), the company would generate $560 million in EBITDA in 2023.
Applying 13x to the spin company EBITDA estimate and 11x to the parent company’s EBITDA estimate, incorporating current net debt of $3.0 billion and 203.4 million shares outstanding, we assign a preliminary, sum-of-the-parts, fair value estimate of $36 per share to MDU.
