Quarterly Report for Quarter Ending September 30, 2026 (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 2025 Annual Report on Form 10-K.

Executive Summary

We are a customer-focused energy solutions provider with a mission of Improving Life with Energy for more than 1.37 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 143 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. We anticipate the transaction closing by year-end 2026, subject to receipt of a satisfactory approval from the MPSC. See Note 14 of the Condensed Notes to Consolidated Financial Statements for further information regarding the pending Merger.

Google Data Center Project

In September 2026, the Company entered into long-term agreements with Google and other third-party partners to serve a planned data center project to be constructed in Cheyenne, Wyoming. The project is contracted to be served through a total resource mix of 2.7 GW, including reserve margins, and is expected to begin taking energy service in late 2027 and ramp to the data center's projected peak load by the end of 2030. We expect to provide up to 590 MW of grid-connected energy service through company-owned generation and market energy. In addition, we expect to manage the output of approximately 2.1 GW of third-party contracted resources through a privately managed microgrid under the Company's LPCS tariff.

To provide 590 MW of grid-connected service, the Company expects to invest approximately $1.8 billion to construct 564 MW (nameplate capacity) of new company-owned natural gas generation between 2027 and 2029 through a non-regulated affiliate, which will be located at the Company's existing CPGS facility. The remaining 26 MW is expected to be supplied through a combination of market energy purchases and retail utility service provided under the Company's applicable industrial tariff.

The Company expects to finance the approximately $1.8 billion of generation investment through a combination of project-generated cash flow and debt and equity instruments with a focus on earnings accretion while maintaining solid investment-grade credit ratings. In connection with the development of the project, the Company previously disclosed customer-funded refundable advances received pursuant to the parties' generation reservation agreement to support procurement of long-lead generation equipment. During the third quarter of 2026, the parties amended the generation reservation agreement to increase the permitted advances to $398.8 million and extend the repayment date to June 30, 2027. The Company expects to reimburse those advances by their June 30, 2027 maturity date.

The agreements include contractual protections throughout the 2048 contract term intended to prevent cost shifting to existing retail customers, including:

•
Cost pass-through mechanisms - protect customers from costs associated with the planned data center while protecting returns from inflation, interest rate volatility, and other cost pressures;
•
Stranded asset risk protection - provides for full recovery of all generation capital investment over the contract term, protecting customers against risk of stranded assets;
•
Early termination protection - safeguard customers and shareholders should the project terminate prior to the end of the agreements' term; and
•
Credit protections - strong collateral and financial assurance requirements back the data center's long-term commitments.

The Company has obtained or initiated key regulatory approvals for the project during 2026, including a substation CPCN approval, the filing of an industrial siting permit for the CPGS expansion, and approval of an air quality permit and an industrial siting permit for the CPGS expansion. Additionally, the Company is advancing transmission expansion opportunities through regulatory filings to serve this project and other regional large-load opportunities. See Business Segment Recent Developments section below with further details on these transmission expansion filings.

Business Segment Recent Developments

Electric Utilities

•
See Note 2 of the Condensed Notes to Consolidated Financial Statements for recent rate review activity for South Dakota Electric and Colorado Electric.
•
In 2026 to date, Wyoming Electric requested approval from the WPSC for a new LCTCAM tariff and CPCNs for two transmission expansion projects with total investment of $686 million to serve the growing energy needs of Wyoming Electric's large-load customers.
o
On June 19, 2026, Wyoming Electric filed a request with the WPSC to establish an LCTCAM tariff. The LCTCAM tariff provides a framework to directly recover transmission investment costs from LPCS customers who are served by, and benefit from, the transmission facilities. The proposed mechanism is designed to ensure that customers not directly served by those facilities are protected from bearing those costs. A WPSC decision is expected in the first quarter of 2027.
o
On September 1, 2026, Wyoming Electric filed a CPCN with the WPSC for its South Cheyenne Transmission Project. The $80 million project includes new substations and nearly 15 miles of transmission lines and upgrades to be in-service in multiple phases in late 2027 through 2028. Recovery is expected to be requested under the LCTCAM, which is currently pending with the WPSC. A WPSC decision on the South Cheyenne Transmission Project CPCN request is expected by mid-2027.
o
On November 2, 2026, Wyoming Electric filed a request with the WPSC for a CPCN for its Aeolus Transmission Project to expand transmission capacity across the Cheyenne region and key interconnection points. The $606 million project includes two new 230-kV transmission lines, with upgrade capabilities to 345-kV, spanning approximately 125 miles. Pending approval by the WPSC, completion of the project is expected by mid-2029. Recovery is expected to be requested under the LCTCAM, which is also pending approval from the WPSC. A WPSC decision on the Aeolus Transmission Project CPCN request is expected by mid-2027.
•
During the third quarter of 2026, South Dakota Electric continued with construction of its Lange II project which is anticipated to be in service by year-end 2026. The addition of these resources will replace generation facilities planned for retirement and support updated planning reserve margin requirements. On August 4, 2026, South Dakota Electric filed an application with the SDPUC for a PIPR rider which requests recovery of $320 million of Lange II project costs outside of a general rate review. If approved by the SDPUC, the rider is anticipated to be effective on December 1, 2026.
•
On September 11, 2026, Colorado Electric filed its 2026 Clean Energy Plan with the CPUC. The updated plan builds on Colorado Electric's 2022 Clean Energy Plan. The plan includes a 25-year planning horizon and reliably achieves Colorado's statutory requirement to reduce greenhouse gas emissions by 80% by 2030, based on 2005 levels. To meet these objectives, the plan proposes the addition of 100 MW of wind energy, 200 MW of battery energy storage systems and 125 MW of firm, dispatchable natural gas-fired generation.
•
On March 12, 2026, the state of South Dakota enacted comprehensive wildfire liability mitigation legislation (Senate Bill 36), effective July 1, 2026. The legislation provides material liability protections for a utility that complies with its published wildfire mitigation plan. On July 2, 2026, South Dakota Electric filed its WMP with the SDPUC. Under Senate Bill 36, a utility's WMP is valid and current if it is on file and all annual reports are timely filed with the SDPUC. In 2025, the state of Wyoming enacted similar legislation. In November 2025, Wyoming Electric filed its WMP with the WPSC, which was approved on July 9, 2026.
•
On June 30, 2026, Wyoming Electric submitted an IRP to the WPSC. The IRP, which is based on 20-year planning period including a near-term planning period through 2033, identified a near-term capacity shortfall of 95 MW beginning in 2027. Based on its forecasts and analysis, Wyoming Electric recommends the addition of natural gas-fired generation, battery storage assets and energy market purchases to meet the identified resource need. Wyoming Electric's IRP does not address any LPCS Tariff capacity needs, which are handled separately under customer-specific agreements.
•
In 2026, Wyoming Electric has set multiple all-time records for System Peak Demand driven by growth in large-load data center demand. The most recent all-time peak of 439 MW was set on July 20, 2026. Prior to 2026, the previous all-time peak was 379 MW set on June 20, 2025.
•
In 2025, Colorado Electric received CPUC approval for the addition of 250 MW of new renewable generation resources in support of its Clean Energy Plan, which included a 50-MW utility-owned battery storage project and a 200-MW solar PPA. During the fourth quarter of 2025, Colorado Electric commenced construction of the 50-MW battery storage project. The project is expected to be completed by year-end 2027. On February 18, 2026, Colorado Electric entered into a 200-MW solar PPA. See Note 3 of the Condensed Notes to Consolidated Financial Statements for additional information regarding the PPA.

Gas Utilities

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

Corporate and Other

•
See Note 5 of the Condensed Notes to Consolidated Financial Statements for information regarding recent financing activities.
•
During the second quarter of 2026, we published our 2025 Corporate Sustainability Report, highlighting our environmental, social and governance impacts and our progress on major projects and climate goals. We reported a 43% reduction in electric utility emissions intensity compared to 2005, driven by the addition of renewable and natural gas resources and the retirement of aging power plants. We also reduced natural gas utility emissions by 25% since 2022, including a 53% reduction from transfer stations, reflecting progress toward our net-zero by 2035 goal through expanded leak detection and repair efforts.

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, 2026, and 2025, and our financial condition as of September 30, 2026, and December 31, 2025, 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.

(a)
Includes inter-segment eliminations.

Three Months Ended September 30, 2026, Compared to the Three Months Ended September 30, 2025:

•
Electric Utilities' operating income increased $14.5 million primarily due to new rates driven by the South Dakota Electric rate review (interim rates effective August 2026) and rider recovery driven by Wyoming Electric's Ready Wyoming project, favorable weather and increased retail customer usage.
•
Gas Utilities' operating income increased $4.2 million primarily due to new rates and rider recovery driven by the Nebraska Gas rate review, increased retail customer usage, increased transportation volumes, and favorable weather partially offset by higher operating expenses.

Nine Months Ended September 30, 2026, Compared to the Nine Months Ended September 30, 2025:

•
Electric Utilities' operating income increased $31.4 million primarily due to new rates and rider recovery driven by the Colorado Electric and South Dakota Electric rate reviews and Wyoming Electric's Ready Wyoming project partially offset by higher operating expenses.
•
Gas Utilities' operating income increased $5.4 million primarily due to new rates and rider recovery driven by the Nebraska Gas and Kansas Gas rate reviews, increased transportation volumes and customer growth partially offset by unfavorable weather and higher operating expenses.
•
Corporate and Other operating loss increased $5.8 million primarily due to higher costs related to the pending Merger and the prior year consolidation of our Captive insurance cell.
•
Net interest expense increased $4.1 million primarily due to higher rates on higher debt balances.
•
Income tax expense increased $2.0 million due to higher pre-tax income partially offset by a lower effective tax rate primarily driven by increased current year tax benefits from federal PTCs associated with increased wind production.
•
Net income attributable to non-controlling interest increased $2.4 million due to higher net income from Black Hills Colorado IPP primarily driven by prior 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:

Operating loss was comparable primarily due to lower costs related to the pending Merger mostly offset by higher unallocated employee costs and the prior year consolidation of our Captive insurance cell.

Nine Months Ended September 30, 2026, Compared to the Nine Months Ended September 30, 2025:

•
Operating loss increased due to $11.7 million of current year costs related to the pending Merger compared to $8.4 million for the same period in 2025. The remaining variance is primarily driven by the prior year consolidation of our Captive insurance cell.

•
Income tax (expense) increased compared to the same period in the prior year primarily due to higher pre-tax income. For the three months ended September 30, 2026, the effective tax rate was 11.8%, which was lower compared to 13.4% for the same period in 2025. The lower effective tax rate was primarily driven by increased current year tax benefits from federal PTCs associated with increased wind production and the non-deductibility of certain prior year costs related to the pending Merger.

Nine Months Ended September 30, 2026, Compared to the Nine Months Ended September 30, 2025:

•
Interest expense, net, increased compared to the same period in the prior year primarily driven by higher debt balances partially offset by higher AFUDC debt driven by construction work-in-progress balances.
•
Other income, net, was comparable to the same period in the prior year.
•
Income tax (expense) increased compared to the same period in the prior year primarily due to higher pre-tax income. For the nine months ended September 30, 2026, the effective tax rate was 11.6%, which was lower compared to 12.2% for the same period in 2025. The lower effective tax rate was primarily driven by increased current year tax benefits from federal PTCs associated with increased wind production.

Future Financing Plans

We plan to fund our capital plan and strategic objectives by using cash generated from operating activities and various financing alternatives, which could include our Revolving Credit Facility, our CP Program, the issuance of common stock under our ATM or in a secondary offering, a term loan and refundable advances from customers. We plan to re-finance our $400 million, 3.15%, senior unsecured notes due January 15, 2027, at or before the maturity date.

As discussed in the Recent Developments section above, the Company expects to finance the approximately $1.8 billion of generation investment through a combination of project-generated cash flow and debt and equity instruments with a focus on earnings accretion while maintaining solid investment-grade credit ratings. Google has provided us with $398.8 million of refundable advances for the procurement of long lead-time equipment under the parties' generation reservation agreement. We expect to reimburse those advances by their June 30, 2027 maturity date.

•
Total earnings (net income plus non-cash adjustments) were $48.6 million higher than 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 financing costs.
•
Net inflows from changes in certain operating assets and liabilities were $0.3 million lower, primarily attributable to:
o
Cash inflows increased by $55.2 million as a result of changes in accounts receivable and other current assets primarily driven by fluctuations in commodity prices and weather, and receipt of an insurance loss recovery receivable related to a legal settlement in Colorado;
o
Cash outflows increased by $10.1 million as a result of changes in accounts payable and other current liabilities primarily driven by fluctuations in commodity prices, payment of a legal liability from settlement in Colorado and changes in other working capital requirements; and
o
Cash inflows decreased by $45.4 million as a result of changes in our regulatory assets and liabilities primarily due to lower recoveries of gas and fuel cost adjustments driven by fluctuations in commodity prices, and lower recoveries of our Winter Storm Uri regulatory asset as recovery is now complete in nearly all jurisdictions.
•
Cash outflows from other operating activities increased by $11.0 million primarily driven by settlement of contractor retainage balances from Wyoming Electric's completed Ready Wyoming project and higher costs from cloud computing arrangements.

The amount of any future cash dividends to be declared and paid, if any, will depend upon, among other things, our financial condition, funds from operations, the level of our capital expenditures, restrictions under our Revolving Credit Facility, and our future business prospects.
