Detailed Financial Performance
NorthWestern Energy Group delivered a robust financial performance for Q2 2026. Net income rose to \$25.0 million (\$0.40 per diluted share), compared to \$21.2 million (\$0.35 per diluted share) in Q2 2025. The increase was primarily driven by new rates and higher retail volumes, partially offset by higher operating, administrative, and general costs, including \$3.3 million in merger-related expenses, as well as increased costs from additional ownership in Colstrip Units 3 and 4, higher depreciation, and interest expense.
Adjusted non-GAAP net income for Q2 2026 was \$31.1 million (\$0.50 per diluted share), reflecting adjustments for unfavorable weather, merger costs, and unrecovered Colstrip Avista expenses.
Merger with Black Hills Corporation: Strategic and Price-Sensitive Updates
NorthWestern Energy’s all-stock merger of equals with Black Hills Corporation is progressing steadily. The new combined entity will be named Bright Horizon Energy. As of July 2026, the merger has secured regulatory approvals from the Federal Energy Regulatory Commission (FERC), Nebraska Public Service Commission, and South Dakota Public Utilities Commission. The only outstanding approval is from the Montana Public Service Commission (MPSC), where a final hearing was held in May 2026 and a decision is pending.
The companies anticipate closing the transaction by year-end 2026, subject to remaining conditions. During the first half of 2026, NorthWestern incurred \$6.7 million in merger-related costs. The timing and outcome of the Montana approval, as well as the integration process, are likely price-sensitive events that could impact share value.
2026 and Long-Term Outlook: Guidance and Capital Investments
- 2026 non-GAAP EPS guidance is reaffirmed at \$3.68–\$3.83 per share, assuming normal weather, exclusion of merger costs, PCCAM waivers, and a 14–18% tax rate.
- Long-term EPS and rate base growth are expected at 4%–6% from a 2024 baseline.
- Capital plan: \$683 million for 2026 and \$3.2 billion for 2026–2030, supporting rate base growth and system reliability.
- Funding for capital expenditures will utilize cash flows, credit, debt, and, for South Dakota investments, equity issuances starting in 2027.
Dividend Policy Update
The Board declared a \$0.67 per share dividend, payable September 1, 2026, adjusting payment timing to align with the pending merger. NorthWestern maintains a long-term payout ratio target of 60–70%.
Strategic and Regulatory Developments
Montana Rate Review
The MPSC’s December 2025 order approved a partial settlement and temporarily suspended the 90/10 PCCAM cost sharing. However, a portion of the Yellowstone County Generating Station (YCGS) capital costs was disallowed, leading to a \$30.9 million non-cash charge. NorthWestern has filed for reconsideration, which could affect 2026 results.
Large New Load Tariff Rule (LNL Rule)
NorthWestern filed for MPSC approval of a new tariff to govern electric service for large new loads (data centers, etc.), including a framework for agreements and protections for existing customers. For loads over 50 MW, MPSC review is required before service begins.
Data Center Agreements
Agreements with Sabey Data Centers, Atlas Power Holdings, and Quantica Infrastructure are in place, with a projected 150 MW load by late 2027 and potential growth to over 1,500 MW by 2030. Execution of these agreements is pending further regulatory review.
Colstrip Acquisitions
- Acquired Avista’s (222 MW) and Puget’s (370 MW) interests in Colstrip Units 3 & 4 for \$0, effective January 1, 2026.
- Operating costs for these assets are not yet in base rates. Avista costs are subject to a temporary PCCAM waiver (approved on an interim basis), but power prices were insufficient to recover operating costs in H1 2026.
- Puget interests are currently contracted out through late 2027, with FERC-approved cost-based rates. MPSC commissioners have appealed the FERC decision, and NorthWestern is intervening in the case.
South Dakota Generation and Transmission Investments
NorthWestern plans a 131 MW natural gas facility in Aberdeen, SD (~\$300 million), responding to new SPP reliability requirements. \$42.3 million in turbine milestone payments recorded as of June 30, 2026.
The company is also progressing on a 10% (300 MW) stake in the North Plains Connector transmission project (Grid United), with construction targeted for 2028–2032, subject to regulatory approvals. Additional transmission development in Montana is being explored.
South Dakota Wildfire Legislation
Senate Bill 36, effective March 2026, protects utilities from certain liabilities related to wildfire damages, provided they have valid mitigation plans. NorthWestern expects to file its plan in Q3 2026.
Financing and Liquidity Update
- April 2026: Issued \$150 million South Dakota First Mortgage Bonds (5.51% due 2036); proceeds used to redeem existing bonds, pay down credit facility, and for general purposes.
- May 2026: Entered \$225 million secured term loan, maturing November 2027, secured by Montana First Mortgage Bonds.
- Liquidity: \$339.2 million as of June 30, 2026 (\$4.2 million cash, \$335 million credit facility).
Financial Table Summaries
- Q2 2026 Revenues: \$392.6 million (Electric: \$324.3M; Gas: \$68.3M)
- Operating Expenses: \$328.4 million (excl. fuel/purchased supply: \$238.6M)
- Operating Income: \$64.2 million
- Interest Expense: \$40.3 million (up from \$36.3M in Q2 2025)
- Net Income: \$25.0 million
Notably, utility margin rose 13.2% year-over-year, with electric margin up 14.4% and natural gas up 8%.
Risk Factors and Forward-Looking Statements
The company cautions that actual outcomes may differ due to risks including: the timing and outcome of the pending merger, regulatory and legal proceedings, ability to recover Colstrip costs, large load customer attraction and regulatory approval, market and weather volatility, supply chain constraints, and other external events. The pending merger remains a key price-sensitive catalyst.
Upcoming Events
NorthWestern will host an investor earnings webinar on July 30, 2026, at 3:30 p.m. ET. Registration details and earnings materials are available on the company website.
Conclusion
NorthWestern Energy’s Q2 2026 results reflect resilient earnings, robust capital planning, and significant strategic progress, notably the pending merger with Black Hills Corporation and major infrastructure and customer growth initiatives.
