Quarterly Report for Quarter Ending September 30, 2025 (Form 10-Q)

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussions should be read in conjunction with the Notes contained herein and Management's Discussion and Analysis of Financial Condition and Results of Operations appearing in our 2024 Annual Report on Form 10-K.

Executive Summary

We are a customer-focused energy solutions provider with a mission of Improving Life with Energyfor more than 1.35 million customers and 800+ communities we serve. Our aspiration is to be the trusted energy partner across our growing eight-state footprint, including Arkansas, Colorado, Iowa, Kansas, Montana, Nebraska, South Dakota, and Wyoming. Our strategy is centered on four priorities: People & Culture-build a team that wins together, Operational Excellence-relentlessly deliver on our commitment to serve our customers, Transformation-be a simple and connected company and Growth-grow to be a dominant long-term energy provider.

We conduct our business operations through two operating segments: Electric Utilities and Gas Utilities. Certain unallocated corporate expenses that support our operating segments are presented as Corporate and Other. We conduct our utility operations under the name Black Hills Energy predominantly in rural areas of the Rocky Mountains and Midwestern states. We consider ourselves a domestic electric and natural gas utility company.

We have provided energy and served customers for 141 years, since the 1883 gold rush days in Deadwood, South Dakota. Throughout our history, the common thread that unites the past to the present is our commitment to serve our customers and communities. By being responsive and service focused, we can help our customers and communities thrive while meeting rapidly changing customer expectations.

Recent Developments

Pending Merger with NorthWestern

On August 18, 2025, we entered into the Merger Agreement with NorthWestern and Merger Sub. See Note 14of the Condensed Notes to Consolidated Financial Statements for further discussion about the pending Merger.

One Big Beautiful Bill Act

See Note 11of the Condensed Notes to Consolidated Financial Statements for discussion surrounding the OBBBA.

Trade Tariffs

Trade tariffs have been enacted over the last several months through presidential executive orders affecting products exported by several U.S. trading partners, and retaliatory tariffs have been imposed by some of these trading partners. While some tariffs scheduled to take effect were temporarily suspended, broad tariffs remain in effect with the possibility of additional tariffs being imposed. We are currently unable to predict the impact that recently imposed and possible future tariffs may have on our business. Trade tariffs have not had a material impact on our operations or financial performance to date. We are closely monitoring the impacts of trade tariffs and the potential effect they may have on our financial position, results of operations, or cash flows.

Business Segment Recent Developments

Electric Utilities

See Note 2of the Condensed Notes to Consolidated Financial Statements for recent rate review activity for Colorado Electric.
On March 6, 2025, the state of Wyoming enacted comprehensive wildfire mitigation legislation (HB0192), effective July 1, 2025. The legislation provides material liability protections for a utility that complies with its commission-approved wildfire mitigation plan. The legislation provides a utility a presumption of meeting an appropriate level of operating care for compliance with an approved wildfire mitigation plan. We plan to file our wildfire mitigation plan with the WPSC in the fourth quarter of 2025.
In 2024, we published our formal WMP, which is an overview of our three-layered approach to manage wildfire risks driven by asset-based risk assessments that include asset programs, integrity programs and operational response. On June 30, 2025, we established our Emergency PSPS program across all three of our electric utilities to promote customer safety and mitigate wildfire risk. In establishing the Emergency PSPS program, we engaged with wildfire experts and key stakeholders including customers, community and local agencies, regulators and community leaders.
In the first half of 2025, Wyoming Electric set four new all-time peak loads, including an all-time peak of 379 MW on June 20, 2025. Prior to 2025, the previous all-time peak was 314 MW set on January 11, 2024.
In 2024, Colorado Electric received CPUC approval for the addition of 350 MW of new renewable generation resources in support of its Clean Energy Plan, which included a 50-MW utility-owned battery storage project, a 200-MW solar PPA and a 100-MW utility-owned solar project. On October 8, 2025, Colorado Electric filed a settlement with the CPUC for its request for a CPCN for the 50-MW battery storage project and anticipates a decision by year-end. On October 29, 2025, the CPUC recommended continuing negotiations on the 200-MW solar PPA but recommended no further action on the 100-MW utility-owned solar project.
On March 28, 2025, South Dakota Electric filed a CPCN with the WPSC for the Lange II project, which was approved in June 2025. The new facility began construction in the third quarter of 2025 and is anticipated to be in service in the second half of 2026.
During the third quarter of 2025, Wyoming Electric continued construction of its approximately 260-mile, $350 million Ready Wyoming electric transmission expansion project. The project is on track and expected to be completed and in service by year-end 2025.

Gas Utilities

See Note 2of the Condensed Notes to Consolidated Financial Statements for recent rate review activity for Iowa Gas, Kansas Gas and Nebraska Gas.

Corporate and Other

See Note 5of the Condensed Notes to Consolidated Financial Statements for information regarding our corporate Revolving Credit Facility, October 2, 2025, debt offering and ATM program activity.
During the second quarter of 2025, we published our 2024 Corporate Sustainability Report, highlighting our environmental, social and governance impacts and our progress on major projects and climate goals.
On January 17, 2025, Fitch affirmed BHC's long-term issuer rating at BBB+ with a negative outlook. Following the affirmation, the parties jointly withdrew the rating. See Liquidity and Capital Resourcessection below for additional information on our credit ratings.

Results of Operations

Certain lines of business in which we operate are highly seasonal, and revenue from, and certain expenses for, such operations may fluctuate significantly among quarterly periods. Demand for electricity and natural gas is sensitive to seasonal cooling, heating and industrial load requirements. In particular, the normal peak usage season for our Electric Utilities is June through August while the normal peak usage season for our Gas Utilities is November through March. Significant earnings variances can be expected between the Gas Utilities segment's peak and off-peak seasons. Due to this seasonal nature, our results of operations for the three and nine months ended September 30, 2025, and 2024, and our financial condition as of September 30, 2025, and December 31, 2024, are not necessarily indicative of the results of operations and financial condition to be expected as of or for any other period or for the entire year.

All amounts are presented on a pre-tax basis unless otherwise indicated. Minor differences in amounts may result due to rounding.

Includes inter-segment eliminations.

Three Months Ended September 30, 2025, Compared to the Three Months Ended September 30, 2024

Electric Utilities' operating income decreased $2.7 million primarily due to milder weather and higher operating expenses partially offset by new rates and rider recovery;
Gas Utilities' operating income increased $9.9 million primarily due to new rates and rider recovery driven by the Arkansas Gas, Kansas Gas, and Nebraska Gas rate reviews and lower operating expenses partially offset by the unfavorable margin impacts of wet summer weather on Nebraska irrigation loads;
Corporate and Other operating loss increased $4.3 million primarily due to NorthWestern merger-related costs partially offset by an unallocated favorable true-up of operating expenses; and
Interest expense, net, increased $4.2 million primarily due to higher CP Program borrowings and lower interest income on lower cash and cash equivalents balances partially offset by higher AFUDC debt driven by construction work-in-progress balances related to the Lange II and Ready Wyoming projects.

Nine Months Ended September 30, 2025, Compared to the Nine Months Ended September 30, 2024:

Electric Utilities' operating income decreased $10.3 million primarily due to higher operating expenses, unplanned generation outages, lower transmission services revenues and unfavorable weather partially offset by new rates and rider recovery;
Gas Utilities' operating income increased $43.1 million primarily due to new rates and rider recovery driven by the Arkansas Gas, Iowa Gas, Kansas Gas, and Nebraska Gas rate reviews and favorable weather partially offset by higher operating expenses;
Corporate and Other operating loss increased $6.5 million primarily due to NorthWestern merger-related costs;
Interest expense, net, increased $17.7 million due to higher interest rates on long-term debt, higher CP Program borrowings and lower interest income on lower cash and cash equivalents balances partially offset by higher AFUDC debt driven by construction work-in-progress balances related to the Lange II and Ready Wyoming projects;
Other income, net, increased $2.8 million primarily due to higher AFUDC equity driven by construction work-in-progress balances related to the Lange II and Ready Wyoming projects;
Income tax expense increased $2.9 million primarily due to higher pre-tax income; and
Net income attributable to non-controlling interest decreased $3.1 million due to lower net income from Black Hills Colorado IPP primarily driven by current year unplanned generation outages.

Segment Operating Results

A discussion of operating results from our business segments follows. Unless otherwise indicated, segment information does not include inter-segment eliminations.

Non-GAAP Financial Measures

The following discussion includes financial information prepared in accordance with GAAP and a "non-GAAP financial measure", Electric and Gas Utility margin. Generally, a non-GAAP financial measure is a numerical measure of a company's financial performance, financial position or cash flows that excludes (or includes) amounts that are included in (or excluded from) the most directly comparable measure calculated and presented in accordance with GAAP. We define Electric and Gas Utility margin as operating revenue less cost of fuel, purchased power and cost of natural gas sold. Electric and Gas Utility margin is a non-GAAP financial measure due to the exclusion of operation and maintenance expenses determined to be directly attributable to revenue-producing activities, depreciation and amortization expenses, and taxes other than income taxes from the measure.

We believe that Gas and Electric Utility margin provides a useful basis for evaluating our segment operating results since our Utilities have regulatory mechanisms that allow them to pass prudently incurred costs of energy through to the customer in current rates. As a result, management uses Gas and Electric Utility margin internally when assessing the financial performance of our operating segments as this measure excludes the majority of revenue fluctuations caused by changes in these costs of energy. Similarly, the presentation of Gas and Electric Utility margin is intended to supplement investors' understanding of operating performance.

Our Electric and Gas Utility margin measure may not be comparable to other companies' Electric and Gas Utility margin measures. The following table includes a reconciliation of Electric and Gas Utility margin to Gross margin, the most directly comparable GAAP measure:

Other income (expense), net, was comparable to the same period in the prior year.
Income tax (expense) was comparable to the same period in the prior year. For the three months ended September 30, 2025, the effective tax rate was 13.5%, compared to 10.0% for the same period in 2024. The higher effective tax rate was primarily driven by non-deductibility of certain NorthWestern merger-related expenses.

Nine Months Ended September 30, 2025, Compared to the Nine Months Ended September 30, 2024:

Interest expense, net, increased due to higher interest rates on long-term debt, higher CP Program borrowings and lower interest income on lower cash and cash equivalents balances partially offset by higher AFUDC debt driven by construction work-in-progress balances related to the Lange II and Ready Wyoming projects.
Other income, net, increased primarily due to higher AFUDC equity driven by construction work-in-progress balances related to the Lange II and Ready Wyoming projects;
Income tax (expense) was comparable to the same period in the prior year. For the nine months ended September 30, 2025, the effective tax rate was 12.2%, which was comparable to 11.4% for the same period in 2024.

Nine Months Ended September 30, 2025, Compared to the Nine Months Ended September 30, 2024

Total earnings (net income plus non-cash adjustments) were $21.6 million higher for the nine months ended September 30, 2025, compared to the same period in the prior year primarily as a result of increased Electric and Gas Utility margins due to new rates and rider recovery partially offset by higher operating expenses, NorthWestern merger-related costs and higher financing costs.
Net inflows from changes in certain operating assets and liabilities were $86.1 million lower, primarily attributable to:
o
Cash inflows decreased by approximately $63.0 million as a result of changes in accounts receivable and other current assets primarily driven by fluctuations in commodity prices;
o
Cash outflows increased by approximately $8.6 million as a result of increases in accounts payable and other current liabilities primarily driven by fluctuations in commodity prices, remediation costs for our manufactured gas plant site in Iowa and changes in other working capital requirements; and
o
Cash inflows decreased by approximately $14.5 million as a result of changes in our regulatory assets and liabilities primarily due to lower recoveries of our Winter Storm Uri regulatory asset as recovery is now complete in several of our jurisdictions.
Cash outflows decreased $3.7 million from other operating activities primarily due to lower costs from cloud computing arrangements.

Cash outflows increased by $4.7 million for other investing activities primarily due to higher AFUDC debt driven construction work-in-progress balances related to the Lange II and Ready Wyoming projects.

Dividends paid on common stock increased $11.0 million due to the increased dividend rate per share and increased number of common shares outstanding;
Cash inflows increased $37.6 million due to increased issuances of common stock;
Net cash outflows decreased $124.7 million primarily as a result of net repayment activity under our CP Program and the prior year repayment of $600 million, 1.04% senior unsecured notes on their August 2024 maturity date partially offset by prior year proceeds from the May 2024, debt offering of $450 million, 6.00% senior unsecured notes;
Distributions to non-controlling interests decreased $7.3 million due to lower net income from Black Hills Colorado IPP primarily driven by unplanned generation outages; and
Cash outflows decreased $5.7 million from other financing activities primarily due to prior year financing costs from the May 2024 debt offering.
