Rhea-AI Filing Summary

Black Hills Corp. reported first-quarter 2026 net income available for common stock of $131.0 million and diluted EPS of $1.73, down from $1.87 a year earlier, mainly reflecting mild winter weather and higher financing and depreciation costs. Adjusted EPS was $1.79 versus $1.87, excluding $0.05 per share of merger-related costs. Revenue was $780.7 million compared with $805.2 million in 2025, with weather reducing results by $0.18 per share but partially offset by new rates, riders, and lower operations and maintenance expenses.

The company reaffirmed 2026 adjusted EPS guidance of $4.25 to $4.45, based on normal weather, constructive regulatory outcomes, equity issuance of $50–$70 million, and an effective tax rate of about 14%. Black Hills highlighted progress on its tax-free, all-stock merger with NorthWestern Energy, including shareholder approvals, settlements with intervenors in multiple states, completion of the Hart-Scott-Rodino waiting period, and an expected closing in the second half of 2026, subject to remaining conditions. It also emphasized a growing data center pipeline of more than 3 GW, including a prospective 1.8 GW project in Wyoming backed by $201 million in refundable customer contributions to reserve generation equipment.

Operationally, Wyoming Electric served a new all-time peak load of 393 MW, marking 20 consecutive years of demand growth in the Cheyenne region. Construction continued on key projects, including the 99-MW, $280 million Lange II gas-fired generation facility in South Dakota and a 50-MW battery storage project in Colorado, along with a new power purchase agreement for up to 200 MW of solar energy. Multiple electric and gas utilities pursued rate reviews seeking new annual revenue in several states. The board declared a quarterly dividend of $0.703 per share, extending the company’s record to 56 consecutive years of dividend increases, and the company issued 0.6 million new common shares for net proceeds of $41 million under its at-the-market program.

Insights

Modest weather-driven EPS pressure but guidance and merger plans remain intact.

Black Hills Corp. delivered softer first-quarter 2026 results, with revenue of $780.7 million versus $805.2 million a year earlier and GAAP diluted EPS of $1.73 versus $1.87. Management attributed $0.18 per share of headwind to mild winter weather and cited higher financing and depreciation costs.

Non-GAAP adjusted EPS was $1.79 compared with $1.87, reflecting $4.6 million in merger-related costs. Despite this, the company reaffirmed its 2026 adjusted EPS guidance range of $4.25 to $4.45 per share, assuming normal weather, constructive regulatory outcomes, equity issuance between $50 million and $70 million, and an effective tax rate of about 14%. This indicates management’s confidence in underlying utility fundamentals.

The pending tax-free, all-stock merger with NorthWestern Energy Group, Inc. advanced through shareholder approvals, regulatory settlements in several states, and completion of the Hart-Scott-Rodino waiting period, with closing expected in the second half of 2026 subject to remaining conditions. Parallel investments in the $280 million, 99-MW Lange II plant, a 50-MW battery project, and a more than 3 GW data center pipeline, including a prospective 1.8 GW project supported by $201 million in customer contributions, underscore a long-term growth focus balanced against continued rate review activity across states.

adjusted EPS financial
"First-quarter adjusted EPS of $1.79, excluding $0.05 of after-tax merger-related costs"
Adjusted earnings per share (adjusted eps) is a measure of a company's profit per share that has been modified to exclude certain one-time or unusual items, such as costs from restructuring or asset sales. It provides a clearer picture of the company’s core performance by removing events that may distort the usual earnings. Investors use adjusted eps to better understand a company's ongoing profitability and compare it more accurately over time.
contributions in aid of construction financial
"The customer has provided $201 million in refundable contributions in aid of construction"
Contributions in aid of construction are one-time payments from customers, developers, or governments that cover part of the cost to build infrastructure—such as power lines, pipelines, or roads—that a utility or infrastructure company would otherwise pay for. Think of it like neighbors chipping in to pave a shared driveway: it reduces the company’s upfront spending, can lower future rates or fees for other customers, and changes reported assets and cash flow, so investors watch it for its impact on capital needs and future earnings.
rate review regulatory
"filed a rate review request with the South Dakota Public Utilities Commission seeking approval"
Rate review is a regulatory check where an insurer, utility, or other regulated service provider submits proposed price or premium increases to a government agency for examination and possible approval or modification. It matters to investors because the outcome determines how much revenue the company can charge customers, affecting earnings, profit margins and demand; think of it like a landlord asking the city for permission to raise rents, with regulators able to limit or reshape the increase.
weather normalization mechanism regulatory
"Nebraska Gas received NPSC approval to develop a two-year pilot program for a weather normalization mechanism"
Hart-Scott-Rodino Act regulatory
"The waiting period was completed under the Hart-Scott-Rodino Act on April 20, 2026"
A U.S. antitrust law that requires parties to large mergers and acquisitions to notify federal regulators and wait a set period before closing the deal, so authorities can check whether the transaction would unfairly reduce competition. For investors, the process is like notifying a referee before a major team trade: it can reveal objections, trigger investigations, delay or block a deal, and therefore affect transaction timing, value and deal risk.
non-GAAP financial measures financial
"the company has presented non-GAAP Adjusted earnings and Adjusted EPS"
Non-GAAP financial measures are numbers companies use to show their financial performance that exclude certain expenses or income. They help investors see how the company might perform without one-time costs or other unusual items, giving a different perspective from official reports. However, since they can be adjusted, they don’t always tell the full story and should be looked at alongside standard financial figures.

During the three months ended March 31, 2026, Black Hills incurred costs of $0.05 per share, related to the pending merger with NorthWestern Energy. See additional details in the GAAP-to-Non-GAAP reconciliation table in the Use of Non-GAAP Financial Measures section below. Minor differences may result due to rounding.

 

First-quarter GAAP EPS was $1.73 compared to $1.87 in the same period in 2025. First-quarter adjusted EPS of $1.79, excluding $0.05 of after-tax merger-related costs, compared to $1.87 in the same period in 2025. Financial results included $0.18 per share of weather impacts from mild winter temperatures, and higher financing and depreciation costs, which were partially offset by new rates and rider recovery and lower operations and maintenance expenses.

 

“I'm proud of the strong operational performance by our team and progress on our strategic initiatives in 2026 to date, providing us confidence in reaffirming our full-year earnings guidance,” said Linn Evans, president and CEO of Black Hills Corp. “We maintained our solid financial position and executed on our capital plan for our customers, including ongoing construction of our 99-MW Lange II generation project in Rapid City that is expected to begin serving customers in the fourth quarter. During the first quarter, we also requested our first rate review in more than a decade for our South Dakota Electric utility, seeking recovery of our investments and costs to serve our customers safely and reliably.

 

“Our data center pipeline of more than 3 GW includes 600 MW by 2030 in our five-year financial plan primarily driven by Microsoft’s expansion of existing operations and Meta’s new AI data center. In addition, we continue to make progress toward definitive agreements to serve other large-load projects, including a 1.8 GW data center, which would be additive to our current plan. We are also excited about Microsoft's recognition of the value of Wyoming and our decades-long relationship, and their recently announced intention to invest in 3,200 acres of additional land for future data center expansion in Cheyenne, which would provide upside potential to our growth pipeline.

 

“Our customer-focused strategy has positioned us to consistently and innovatively deliver safe, reliable, and affordable energy while supporting the needs of our customers and communities for growth. We are confident in our ability to deliver earnings in the upper half of our 4% to 6% long-term EPS growth target, and we look forward to an even stronger energy future for all our stakeholders as a larger, premier Midwest utility following our merger with NorthWestern Energy,” concluded Evans.

 

 


Merger with NorthWestern Energy Group, Inc.

 

Black Hills Corp. and NorthWestern Energy announced a tax-free, all-stock merger on Aug. 19, 2025, which was approved by shareholders of both companies on April 2, 2026. During the first quarter, the companies continued to seek joint approval of the transaction from regulatory commissions in Montana, Nebraska and South Dakota, reaching settlements with certain intervenors in all three states to date. The waiting period was completed under the Hart-Scott-Rodino Act on April 20, 2026, satisfying a U.S. antitrust condition to closing, and the initial public comment period regarding the joint application with the Federal Energy Regulatory Commission closed on Jan. 20, 2026, with a decision expected by mid-2026. The transaction is expected to close in the second half of 2026, subject to the satisfaction or waiver of certain closing conditions.

 

FIRST-QUARTER 2026 HIGHLIGHTS AND RECENT UPDATES

 

Electric Utilities

 

On April 22, Wyoming Electric entered into an agreement to procure long lead-time generation equipment with a prospective data center customer seeking to construct a 1.8 GW data center to be served under Wyoming Electric’s Large Power Contract Service Tariff. The customer has provided $201 million in refundable contributions in aid of construction to date in support of milestone payments to secure generation equipment. The company continues to negotiate several additional definitive agreements with the prospective customer.

 

On March 18, South Dakota Electric filed a rate review request with the Wyoming Public Service Commission seeking approval to recover critical investments since its last rate review in 2014. The rate review requested $5 million of new annual revenue based on a capital structure of 53% equity and 47% debt and a return on equity of 10.5%. The company is seeking new rates in the first quarter of 2027.

 

On March 12, South Dakota enacted wildfire liability legislation, effective July 1, 2026, which provides material liability protections for a utility that complies with its published wildfire mitigation plan. South Dakota Electric plans to file its wildfire mitigation plan with the South Dakota Public Utilities Commission in the second half of 2026.

 

On Feb. 19, South Dakota Electric filed a rate review request with the South Dakota Public Utilities Commission seeking approval to recover critical investments since its last rate review in 2014. The rate review requested $51 million of new annual revenue based on a capital structure of 53% equity and 47% debt and a return on equity of 10.5%. The company is seeking interim rates to be effective 180 days after filing, with new rates to be finalized in the first quarter of 2027.

 

During the first quarter, South Dakota Electric continued construction of its 99 MW, $280 million Lange II gas-fired generation project. The new facility is expected to be completed and in service during the fourth quarter of 2026 to replace generation resources planned for retirement and support updated reserve margin requirements.

 

On Jan. 23, Wyoming Electric recorded a new winter and all-time customer peak load of 393 megawatts, surpassing the previous all-time peak of 379 MW on June 20, 2025. The new peak represents an increase of 4% over the prior all-time peak and 20 consecutive years of increasing electric demand in the Cheyenne, Wyoming region.

 

During the first quarter of 2026, construction continued on Colorado Electric’s 50-MW battery storage project. The project was approved in 2025 by the Colorado Public Utilities Commission in support of the Colorado Clean Energy Plan. Construction was commenced in 2025, and the project is expected to be completed by year-end 2027. On Feb. 18, 2026, Colorado Electric executed a PPA with a third party to purchase up to 200 MW of solar energy upon construction of a new renewable generation facility, which is expected to be completed in mid-2029.

 

Gas Utilities

 

On March 2, Kansas Gas filed an abbreviated rate review request with the Kansas Corporation Commission seeking $2.4 million in new annual revenue for additional capital placed in service through Dec. 31, 2025. The authorized returns for the additional investment recovery were previously approved during the July 2025 rate review. The capital structure and return on equity were approved under a black box settlement agreement.

 

On Dec. 5, 2025, Arkansas Gas filed a rate review request with the Arkansas Public Service Commission seeking approval to recover approximately $147 million of system investments for its natural gas pipeline infrastructure since its last general rate filing in 2023. The rate review requested $29 million of new annual revenue based on a capital structure of 50.2% equity and 49.8% debt and a return on equity of 10.5%. The company is seeking final rates in the second half of 2026.

 

Corporate and Other

 

On April 28, Black Hills’ board of directors approved a quarterly dividend of $0.703 per share payable on June 1, 2026, to common shareholders of record at the close of business on May 15, 2026. On an annualized basis, the dividend represents 56 consecutive years of increases, the second-longest track record in the electric and natural gas industry.

 

During the first quarter, the company issued a total of 0.6 million shares of new common stock under its at-the-market equity offering program for net proceeds of $41 million.

2026 ADJUSTED EARNINGS GUIDANCE REAFFIRMED

 

Black Hills reaffirms its guidance for 2026 adjusted EPS* to be in the range of $4.25 to $4.45, based on the following assumptions:

 

Normal weather conditions within our utility service territories;
Constructive and timely outcomes of utility regulatory dockets;
Excludes merger-related costs;
Excludes mark-to-market adjustments;
Increase in operations and maintenance expense (excludes merger-related costs, depreciation and amortization, and taxes other than income taxes) of approximately 3.5% off 2025 of $580 million;
Equity issuance between $50 million and $70 million; and
An effective tax rate of approximately 14% for the full year.

 

This guidance excludes the expected merger with NorthWestern Energy, which is expected to close in the second half of 2026.

 

* The 2026 Adjusted EPS guidance shown above is a forward-looking, non-GAAP financial measure. The company is not able to provide comparable GAAP EPS guidance due to items that are not considered representative of the company's underlying operating performance that cannot be reasonably quantified for the full-year period. These items include merger-related costs the company expects to incur in 2026, in addition to any other unplanned items that may affect GAAP results in 2026.

3


USE OF NON-GAAP FINANCIAL MEASURES

 

As noted in this earnings release, in addition to presenting its earnings information in conformity with Generally Accepted Accounting Principles (GAAP), the company has presented non-GAAP Adjusted earnings and Adjusted EPS, which reflect adjustments for expenses, gains and losses that the company believes do not reflect ongoing core operating performance, such as costs related to the pending merger with NorthWestern. The company’s management uses non-GAAP measures for financial planning and analysis, for reporting of results to the Board of Directors, in determining performance-based compensation and communicating its earnings outlook to analysts and investors. Non-GAAP financial measures are intended to supplement investors’ understanding of our performance and should not be considered alternatives for financial measures presented in accordance with GAAP. Our non-GAAP measures may not be comparable to those of other companies.

Three Months Ended March 31, 2026, Compared to the Three Months Ended March 31, 2025

 

Electric Utilities’ operating income increased $5.6 million primarily due to new rates from the Colorado Electric rate review and rider recovery from Wyoming Electric's recently completed Ready Wyoming project, partially offset by unfavorable weather and lower residential and commercial customer usage;
Gas Utilities’ operating income decreased $5.0 million primarily due to unfavorable weather, partially offset by new rates and rider recovery driven by the Kansas Gas and Nebraska Gas rate reviews and lower operating expenses; and
Corporate and Other operating loss increased $3.7 million primarily due to costs related to the pending merger with NorthWestern.

CAUTION REGARDING FORWARD-LOOKING STATEMENTS

 

This press release includes “forward-looking statements” as defined by the Securities and Exchange Commission. We make these forward-looking statements in reliance on the safe harbor protections provided under the Private Securities Litigation Reform Act of 1995. All statements, other than statements of historical facts, included in this press release that address activities, events or developments that we expect, believe or anticipate will or may occur in the future are forward-looking statements. This includes, without limitations, our 2026 earnings guidance, long-term growth target and our expectations for regulatory approvals for and the closing of the merger with NorthWestern Energy. These forward-looking statements are based on assumptions which we believe are reasonable based on current expectations and projections about future events and industry conditions and trends affecting our business. However, whether actual results and developments will conform to our expectations and predictions is subject to a number of risks and uncertainties that, among other things, could cause actual results to differ materially from those contained in the forward-looking statements, including without limitation, the risk factors described in Item 1A of Part I of our 2025 Annual Report on Form 10-K and other reports that we file with the SEC from time to time, and the following:

 

The accuracy of our assumptions on which our earnings guidance and long-term growth target is based;
Our ability to obtain adequate cost recovery for our utility operations through regulatory proceedings and favorable rulings on periodic applications to recover costs for capital additions, plant retirements and decommissioning, fuel, transmission, purchased power, and other operating costs and the timing in which new rates would go into effect;
Our ability to complete our capital program in a cost-effective and timely manner;
Our ability to execute on our strategy;
Our ability to successfully execute our financing plans;
The effects of changing interest rates;
Our ability to achieve our greenhouse gas emissions intensity reduction goals;
The impact of future governmental regulation;
Our ability to overcome the impacts of supply chain disruptions on availability and cost of materials;
The effects of inflation, tariffs and volatile energy prices;
Our ability to obtain sufficient insurance coverage at reasonable costs and whether such coverage will protect us against significant losses;
The expected timing and likelihood of completion and our ability to realize the anticipated benefits of the proposed merger with NorthWestern Energy Group, Inc., including the timing, receipt and terms and conditions of any required governmental and regulatory approvals of the proposed acquisition that could reduce anticipated benefits or give rise to the termination of the merger; and
Other factors discussed from time to time in our filings with the SEC.

 

New factors that could cause actual results to differ materially from those described in forward-looking statements emerge from time-to-time, and it is not possible for us to predict all such factors, or the extent to which any such factor or combination of factors may cause actual results to differ from those contained in any forward-looking statement. We assume no obligation to update publicly any such forward-looking statements, whether as a result of new information, future events or otherwise.
