Black Hills Corp (BKH) Q4 2025 earnings review

Reliable Delivery Amidst Electric Margin Compression

Black Hills Corp delivered a solid 'meet' for FY25, landing Adjusted EPS of $4.10, exactly at the midpoint of guidance. While the headline story is one of stability—56 consecutive years of dividend increases and a 5% EPS growth rate—the underlying segment data reveals a divergence. Gas Utilities are carrying the load (Operating Income +18% YoY), masking a deterioration in Electric Utilities profitability (Operating Income -4.5% YoY) despite record peak loads. Management initiated robust 2026 guidance and highlighted a massive data center pipeline, but execution on the pending NorthWestern Energy merger and stabilizing electric margins remain critical watch points.

🐂 Bull Case

Data Center Pipeline Expansion

The data center narrative is shifting from concept to reality. Wyoming Electric hit a new all-time peak load (up 21% YoY) driven by this demand. The pipeline now exceeds 3 GW, with 600 MW included in the 5-year plan, utilizing capital-light tariffs that protect the balance sheet.

Gas Utility Outperformance

Gas Utilities are firing on all cylinders, with FY25 operating income up nearly $50M (+18% YoY). Regulatory execution is precise, with $67M in new rates/riders achieved for gas alone in 2025.

🐻 Bear Case

Electric Segment Stagnation

Despite the data center hype, Electric Utilities operating income fell 4.5% in FY25 ($222.5M vs $233.0M in FY24). Rising O&M and depreciation expenses are outpacing revenue gains, creating a drag on consolidated results.

Merger Overhang

The pending merger with NorthWestern Energy (expected close H2 2026) creates execution risk and noise in the financials ($0.12/share in merger costs for 2025). Regulatory approvals in multiple jurisdictions are required, potentially distracting management from core operations.

⚖️ Verdict: 🟢

Solid. Black Hills is a boringly reliable utility executing well on regulatory recovery and dividend growth. The deterioration in Electric margins is a concern, but the acceleration implied in 2026 guidance suggesting 6% growth offers a compelling offset.

Key Themes

DRIVER🟢🟢

Data Center & Peak Load Explosion

The physical demand for power in Wyoming is surging. Wyoming Electric recorded an all-time peak of 379 MW in 2025, a massive 21% jump over the 2024 peak. This validates the data center thesis. The company has a 3 GW pipeline and plans to serve 600 MW by 2030. Critically, this is being done via 'innovative tariffs' that require minimal capital investment, improving return on equity.

CONCERNNEW🟢

Electric Profitability Lagging Revenue

A concerning divergence has emerged. While Electric Utilities Revenue grew 7.6% in FY25 to $942.8M, Operating Income actually fell 4.5% to $222.5M. Management cites 'higher operating expenses, unplanned generation outages, and lower transmission services' as culprits. If the Data Center boom generates revenue but not profit due to rising costs, the thesis breaks.

THEME

Gas Utilities Carrying the Weight

The Gas segment is the current workhorse. FY25 Operating Income reached $320.8M, up from $271.3M in FY24. This was driven by successful rate reviews in Arkansas, Iowa, Kansas, and Nebraska. The company successfully converted capital investment into authorized recovery, proving the regulatory model works efficiently in these jurisdictions.

CONCERN

Rising Interest Expense

Interest expense remains a headwind, rising 10% YoY to $200.1M in FY25 (vs $181.7M). Higher rates on long-term debt and increased commercial paper borrowings are eating into the operational gains. With a $4.7B capital plan through 2030, financing costs will remain a critical lever.

DRIVERNEW🔴

Ready Wyoming Completion

The 260-mile Ready Wyoming transmission project was energized in Dec 2025. This $350M investment moves from construction to cash-flowing asset in 2026. $300M is recovered via a rider (immediate cash flow) and $50M via base rates. This is a key bridge to the accelerated 2026 guidance.

Other KPIs

FY25 Electric Utilities Operating Income$222.5 million

Reversing. Down from $233.0M in FY24. Despite a 21% increase in peak load in Wyoming and revenue growth, profitability slid due to O&M inflation and outage costs.

FY25 Cash from Operations (Implied)~$600-650M range

Stable. The company maintained FFO/Debt metrics at 14-15%. Liquidity is robust with $747M available on the revolver. Financing the $4.7B capex plan will require continued discipline.

Effective Tax Rate (2026 Guidance)~14%

Slightly higher than the ~13% realized in previous periods, creating a mild headwind for 2026 EPS conversion.

Guidance

2026 Adjusted EPS$4.25 - $4.45

Accelerating. The midpoint of $4.35 implies ~6% YoY growth, an acceleration from the 5% growth achieved in 2025 ($4.10). This aligns with the 'upper half of 4-6%' long-term target.

2026-2030 Capital Investment$4.7 billion

Stable. The plan is heavily weighted toward safety/reliability and customer growth. Includes minimal capital for the 600 MW data center load, protecting free cash flow.

2026 Equity Issuance$50 - $70 million

Decelerating. This is a positive signal. Equity needs are dropping significantly from the $220M issued in 2025, reducing dilution risk for shareholders.

Key Questions

Electric Margin Compression

With Wyoming peak loads up 21% and revenues up 7.6%, why did Electric Operating Income decline 4.5% in FY25? Are these 'unplanned outage' costs structural or one-time?

Merger Synergies vs. Costs

We see the $0.12/share in merger costs for 2025, but when will the financial synergies from the NorthWestern Energy combination begin to accrete to EPS, and is the H2 2026 close timeline at risk given regulatory scrutiny?

Data Center Monetization

You mention minimal capital investment for the 600 MW data center load. Can you clarify the margin profile of these 'innovative tariffs' compared to traditional rate-based returns?
