Black Hills Corporation

Black Hills Corp. is a South Dakota-based regulated utility company that serves electric and natural gas customers across the Rocky Mountain and Midwest regions of the United States. It operates through two core segments: Electric Utilities, which generate, transmit and distribute power, and Gas Utilities, which transport and distribute natural gas. The company also has a smaller non-regulated services business, including energy supply and home service offerings, that supports its regulated customer base. Black Hills is organized around long-term utility infrastructure, with assets such as generation, transmission lines, gas pipelines, storage sites and distribution networks. In 2025, the company announced an all-stock merger with NorthWestern, which would expand its scale and footprint if completed.

Customers

Black Hills serves residential, commercial, industrial and municipal utility customers, with a strong concentration in rural communities across the Rocky Mountains and Midwest. Its electric utility customers are located in Colorado, Montana, South Dakota and Wyoming, while its gas utility customers are spread across Arkansas, Colorado, Iowa, Kansas, Nebraska and Wyoming. The company also sells natural gas supply to retail customers under the Nebraska and Wyoming Choice Gas Program and provides non-regulated service plans to regulated customers. Industrial and large-load customers matter in the electric business because they can materially affect load growth and tariff revenue, while weather-sensitive residential and small business customers are important in the gas business. The pending merger with NorthWestern would further broaden the customer base and increase the scale of the combined utility platform.

Residential utility customers

Households buying electric and natural gas delivery for everyday heating, cooling and essential service reliability.

Commercial and municipal customers

Businesses, schools and public entities buying regulated utility service and infrastructure access for continuity and local service quality.

Industrial and large-load customers

Larger electric users that buy power service and can materially influence load growth, tariff revenue and system planning.

Choice Gas retail customers

Nebraska and Wyoming customers that buy gas supply through the Choice Gas Program because they want supply options tied to regulated delivery.

Non-regulated service customers

Regulated utility customers purchasing add-on protection, comfort and home service products for convenience and equipment support.

Strategy

Black Hills describes its strategy around four priorities: People & Culture, Operational Excellence, Transformation and Growth. The company is trying to be a trusted energy partner across a larger eight-state footprint while keeping the business simple and connected, which is important in a regulated utility model where execution and reliability drive customer and regulator confidence. Growth is tied to long-lived capital investment in electric and gas infrastructure, while operational excellence is meant to improve service quality and control operating costs. The announced merger with NorthWestern is a major strategic step that would increase scale, broaden the service territory and potentially improve long-term operating leverage if approvals are obtained. The company also continues to invest in integrated generation, transmission, distribution and gas infrastructure to support regulated growth and customer service.

People & CultureShort term

Utility performance depends on skilled field, operations and customer-service teams that can safely run critical infrastructure.

Operational ExcellenceShort term

Reliable service, outage management and cost control are essential in a regulated utility where performance affects customer satisfaction and allowed returns.

TransformationMedium term

Simplifying systems and processes can reduce complexity, improve decision-making and support integration of future acquisitions.

GrowthMedium term

Long-term value creation in utilities comes from expanding the rate base and customer footprint through regulated investment and strategic combinations.

Geography

Black Hills is a domestic U.S. utility with operations concentrated in eight states: Arkansas, Colorado, Iowa, Kansas, Montana, Nebraska, South Dakota and Wyoming. Its electric utilities are centered in Colorado, South Dakota and Wyoming, while its gas utilities span Arkansas, Colorado, Iowa, Kansas, Nebraska and Wyoming. The company says it operates predominantly in rural areas of the Rocky Mountains and Midwestern states, which shapes load density, infrastructure needs and service economics. The 2025 merger agreement with NorthWestern is intended to create a larger utility footprint across the same broader regional corridor. Geography matters because weather, population density, regulatory regimes and state-level approvals all directly affect demand, capital spending and allowed returns.

Risks

Black Hills faces the typical risks of a regulated utility, including weather-driven demand variability, regulatory delays, capital intensity and the need to recover large infrastructure investments through approved rates. The company specifically highlights operational limitations, higher compliance and engineering costs, supply chain challenges, workforce constraints and public opposition, all of which can delay projects or raise operating costs. Cybersecurity is a material risk because the business depends on electronic control systems and network infrastructure to generate and deliver energy; a disruption could interrupt service and create liability, repair and reputational costs. Climate-related physical and transition risks also matter because extreme weather can affect demand, asset reliability and maintenance needs, while decarbonization trends can pressure generation and fuel choices. The pending NorthWestern merger adds execution and regulatory approval risk, and the combined company could face goodwill impairment risk if expected synergies or fair values do not materialize.

Accounting

Judgemental items
Regulatory assets and cost recovery

Utility accounting depends on whether costs can be recovered through future rates, which affects asset values and earnings timing.

Impact: Can change reported assets, liabilities and earnings recognition timing

Seasonality and weather normalization

Gas volumes and some electric revenues vary with heating degree days and seasonal demand patterns.

Impact: Creates quarter-to-quarter volatility and affects comparability

Customer receivables and credit losses

The company must estimate collectability of utility bills and related service receivables.

Impact: Affects bad-debt expense and operating cash flow

Goodwill impairment

The company reported a large goodwill balance and the merger could increase it further.

Impact: Could create material non-cash charges if assumptions weaken

Acquisition accounting for NorthWestern merger

The transaction will require fair value measurement of acquired assets and liabilities and recognition of goodwill.

Impact: May materially affect future balance sheet and earnings
