On August 4, 2023, 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 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 private letter ruling regarding the tax-free status of the separation. MDU will distribute at least 80.1% of outstanding shares of Knife River Holdings to MDU shareholders as of a yet-to-be-determined record date, and the company is expected to trade on the NYSE under the ticker “KNF.” MDU will retain up to 19.9% of KNF shares, which the company intends to dispose of via a debt exchange, distribution to shareholders, or in a sale for cash. The separation will be completed on May 31, 2023, after the market close, with shareholders of record as of May 22, 2023, receiving one share of KNF for every four shares of MDU held.
The company describes itself as “a regulated energy delivery and construction materials and services business.” MDU, as it currently stands, operates two main businesses: Regulated Energy Delivery, and Construction Materials and Services. The regulated energy business generates, transmits, and distributes electricity as well as provides transportation, distribution, and storage services for natural gas. The construction materials business mines and markets aggregates and related products, including concrete and asphalt, as well as providing related contracting services. Additionally, the company participates in contracting services for the construction of specialty electrical and mechanical transmission and distribution systems.
Subsequent to the Knife River spin announcement, MDU announced, on November 3, 2022, that management authorized a strategic review that would separate the current Construction Services business from the regulated energy delivery businesses (Natural Gas, Electric, and Pipelines segments). The strategic review is expected to be completed in 2Q 2023.
Given what appears to be the first step in fully separating the regulated businesses from non-regulated, we expect that following the spin-off of Knife River, shares of the regulated business would begin to be re-rated to more closely approximate the underlying utility operators, while Knife River would be comparable to other aggregate and construction services companies. Notably, if the company does end up separating the regulated businesses fully (via another spin-off or through another method such as a sale), the parent MDU company would significantly reduce its earnings volatility, which may attract a more dividend-focused investor base, while Knife River and the third company would attract more industrial/cyclical industry focused investor base.
On a pre-spin, sum-of-the-parts basis, we assign a fair value estimate of $32 per share to MDU Resources. On a post-spin basis, we value shares of Knife River at $28 per share and MDU Resources at $25 per share. Given limited upside to our fair value estimate, we rate shares of MDU at NEUTRAL prior to the Knife River spin-off.
