Third quarter GAAP EPS was $0.34 compared to $0.35 in 2024. Third quarter adjusted EPS of $0.45, excluding $0.10 of merger-related costs, compared to $0.35 in the same period in 2024, benefited from new rates and rider recovery of $0.21 per share, which more than offset higher financing and depreciation costs and unfavorable weather.
Year-to-date GAAP EPS was $2.58 compared to $2.52 in the same period in 2024. Year-to-date adjusted EPS of $2.68, excluding $0.11 of merger-related costs, compared to $2.52 in the same period in 2024 benefited from new rates and rider recovery of $0.68 per share, along with favorable weather, which more than offset higher operating expenses, financing and depreciation costs.
“Our team delivered strong financial and operational results while successfully advancing key regulatory and growth initiatives,” said Linn Evans, president and CEO of Black Hills Corp. “We completed our planned debt and equity financings for the year, maintaining strong credit quality and liquidity. In Nebraska, we secured a settlement for our natural gas rate review and are preparing to file a new Arkansas gas rate review by year-end. We also plan to file an electric rate review in South Dakota during the first quarter of 2026 – our first in more than a decade.
“Our $4.7 billion five-year capital plan prioritizes core customer needs for safety, reliability, and growth. By year-end, our 260-mile Ready Wyoming transmission expansion project will be complete, enabling a more reliable, interconnected grid to serve our customers. In 2026, our 99 MW Lange II generation project in South Dakota will replace aging infrastructure with advanced generation technology.
“Our five-year plan includes 500 MW of data center demand by 2029, driven by continued Microsoft expansion and Meta’s new AI data center, which will transition from construction power to permanent service later this year. We are also actively negotiating with high-quality partners, expanding our data center load pipeline to more than 3 GW from our previously disclosed pipeline of more than 1 GW. This would drive significant earnings growth incremental to our current plan through our innovative data center tariff and strategic investments in new transmission and generation."
Merger with NorthWestern Energy Group, Inc.
Black Hills Corp. and NorthWestern Energy announced a tax-free, all-stock merger on Aug. 19, 2025. In October 2025, the companies filed joint applications for approval of the transaction with regulatory commissions in Montana, Nebraska and South Dakota. The companies anticipate filing an application with the Federal Energy Regulatory Commission (FERC) in the fourth quarter of 2025. The transaction is expected to close in the second half of 2026, subject to the satisfaction or waiver of certain closing conditions.
“We are advancing our proposed merger with NorthWestern Energy to create a premier Midwest utility presence with enhanced scale, resilience, and opportunities for growth as a combined company,” said Linn Evans, president and CEO of Black Hills Corp. “Our joint regulatory filings underscore the transaction’s substantial benefits for our customers and stakeholders.”
THIRD-QUARTER 2025 HIGHLIGHTS AND RECENT UPDATES
Electric Utilities
- During the third quarter, Wyoming Electric continued construction of its 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. The project is expected to maintain long-term cost stability for customers, enhance system resiliency and access to power markets, support local economic growth and facilitate development of Wyoming’s strong wind and solar natural resources.
- During the third quarter, South Dakota Electric commenced construction of its 99-megawatt, $280 million Lange II gas-fired generation project. The new facility is expected to be completed and in service during the second half of 2026. The addition of these resources will replace generation resources planned for retirement and support updated planning reserve margin requirements.
- In 2024, Colorado Electric received approval from the Colorado Public Utilities Commission (CPUC) of a portfolio of projects resulting from a competitive bidding process to pursue its Colorado Clean Energy Plan to reduce emissions 80% by 2030 off a 2005 baseline. The projects included a 50-megawatt utility-owned battery storage project, a 200-megawatt solar power purchase agreement, and a 100-megawatt utility-owned solar project. On Oct. 8, 2025, the company filed a settlement for its request for a certificate of public convenience and necessity for the battery storage project and anticipates approval by year-end. On Oct. 29, 2025, the CPUC recommended continuing negotiations on the 200-megawatt solar power purchase agreement and recommended no further action on the 100-megawatt utility-owned solar project.
Gas Utilities
- On Oct. 7, Nebraska Gas filed for approval from the Nebraska Public Service Commission of a unanimous settlement agreement for its rate review filed May 1, 2025. The settlement, pending commission approval, includes $23.9 million of new annual revenue based on a capital structure of 51% equity and 49% debt, and a return on equity of 9.85%. The settlement also provides renewal of a five-year system safety and integrity rider, an insurance cost recovery tracker, and a two-year weather normalization pilot program. The settlement allows for final rates on Jan. 1, 2026, replacing interim rates that were effective on Aug. 1, 2025.
- On July 24, Kansas Gas received approval from the Kansas Corporation Commission of a settlement agreement for its rate review request seeking approval to recover approximately $118 million of system investments and increased operations and maintenance costs driven by inflation and operational needs to serve customers. The black box settlement provides approximately $10.8 million of new annual revenue, with new rates effective Aug. 1, 2025. The settlement provides the renewal of the company's safety and integrity rider and allows for a new insurance cost tracker with deferred accounting treatment. It also includes approval for the company to file an abbreviated case during the first quarter of 2026 that includes the addition of capital placed in service through Dec. 31, 2025.
Corporate and Other
- On Oct. 28, Black Hills’ board of directors approved a quarterly dividend of $0.676 per share payable on Dec. 1, 2025, to common shareholders of record at the close of business on Nov. 17, 2025. On an annualized basis, the dividend represents 55 consecutive years of increases, the second-longest track record in the electric and natural gas industry.
- On Oct. 2, Black Hills completed a public debt offering of $450 million, 4.55% senior unsecured notes due Jan. 31, 2031. Proceeds will be used to repay the $300 million aggregate principal amount of its notes due Jan. 15, 2026, at or before maturity. Any remaining net proceeds may be used for general corporate purposes.
- During the third quarter, the company issued a total of 2.6 million shares of new common stock for net proceeds of $154 million, including a block equity trade. Year to date, the company has issued a total of 3.7 million shares of new common stock for net proceeds of $220 million.
- During the third quarter, Black Hills maintained its solid investment-grade credit ratings by rating agencies covering the company.
- On Aug. 19, Moody's Ratings affirmed Black Hills' long-term issuer credit rating at Baa2 with a stable outlook
- On Aug. 19, S&P Global Ratings affirmed Black Hills' issuer credit rating at BBB+ with a stable outlook
REAFFIRMS 2025 ADJUSTED EARNINGS GUIDANCE SAME AS PRIOR GAAP GUIDANCE
Black Hills reaffirms its guidance for 2025 adjusted earnings per share available for common stock* to be in the range of $4.00 to $4.20, based on the following assumptions issued on Feb. 5, 2025:
- Normal weather conditions within our utility service territories
- Constructive and timely outcomes of utility regulatory dockets;
- Excludes mark-to-market adjustments;
- No unplanned outages at our generation facilities;
- Compounded annual growth rate of approximately 3.5% for operations and maintenance expense (excludes depreciation and amortization and taxes other than income taxes) off 2023 of $552 million
- Equity issuance between $215 million and $235 million; and
- An effective tax rate of approximately 13% for the full year.
* The 2025 adjusted earnings per share guidance shown above is a forward-looking, non-GAAP financial measure. The company is not able to provide comparable GAAP earnings per share 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 NorthWestern merger-related costs of $0.11 per share for the nine months ended Sept. 30, 2025, as well as additional NorthWestern merger-related costs the company expects to incur in the fourth quarter of 2025, in addition to any other unplanned items that may affect GAAP results during the remainder of 2025.
USE OF NON-GAAP FINANCIAL MEASURES
Adjusted Earnings and Adjusted EPS
As noted in this earnings release, in addition to presenting its earnings information in conformity with Generally Accepted Accounting Principles (GAAP), the company has provided 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.
The company’s management uses these non-GAAP financial measures as indicators for evaluating current periods and planning and forecasting future periods. The company also uses these non-GAAP measures when communicating with analysts and investors regarding our earnings results and outlook, as the company believes that these non-GAAP measures allow the company to more accurately compare its ongoing performance across periods. In providing adjusted earnings guidance, there could be differences between adjusted earnings and earnings prepared in accordance with GAAP as a result of our treatment of certain items, such as those described in the reconciliation below.
Limitations on the Use of Non-GAAP Measures
Non-GAAP measures have limitations as analytical tools and should not be considered in isolation or as a substitute for analysis of our results as reported under GAAP. Our presentation of these non-GAAP financial measures should not be construed as an inference that our future results will not be affected by unusual, non-routine, or non-recurring items. The company is not able to provide a forward-looking quantitative GAAP to Non-GAAP reconciliation for non-GAAP measures due to items that are not considered representative of the company's underlying operating performance that cannot be reasonably quantified, including merger-related costs and any other unplanned items that may affect GAAP results during the remainder of 2025.
Our non-GAAP measures may not be comparable to those of other companies. Non-GAAP measures should be used in addition to and in conjunction with results presented in accordance with GAAP. Non-GAAP measures should not be considered as an alternative to net income, operating income or any other operating performance measure prescribed by GAAP, nor should these measures be relied upon to the exclusion of GAAP financial measures. Our non-GAAP measures reflect an additional way of viewing our operations that we believe, when viewed with our GAAP results and the reconciliation to the corresponding GAAP financial measures, provide a more complete understanding of factors and trends affecting our business than could be obtained absent this disclosure. Management strongly encourages investors to review our financial information in its entirety and not rely on a single financial measure.

Three Months Ended Sept. 30, 2025, Compared to the Three Months Ended Sept. 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 $8.4 million of 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.

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 2025 earnings guidance, long-term growth target and our expectations for regulatory filings 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 2024 Annual Report on Form 10-K, Exhibit 99.4 to our Current Report on Form 8-K filed on Sept. 15, 2025, Item 1A of our forthcoming Quarterly Report on Form 10-Q for the quarter ended Sept. 30, 2025, 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.
