• Weather represented an $0.11 headwind in 2025 when compared to normal conditions.

Risks

• The Crusoe and Tallgrass project, being of significant magnitude, is complex and involves multiple parties, requiring thoughtful structuring and negotiation of project contracts to manage operational and financial risk.
• The need for generation and transmission infrastructure to serve 600 megawatts of data center demand could be accelerated if large load requests reach that level sooner than expected.
• The merger with NorthWestern Energy requires securing all necessary regulatory approvals to finalize.

Future Outlook

Black Hills Corporation anticipates achieving earnings growth in the upper half of its 4% to 6% long-term target, with 2026 adjusted EPS guidance of $4.25 to $4.45 per share, representing 6% year-over-year growth. The company expects significantly lower equity needs for 2026 and projects data center demand to contribute over 10% of consolidated EPS starting in 2028. The strategic merger with NorthWestern Energy is expected to finalize in the second half of 2026, creating a stronger, more competitive utility with increased scale and new opportunities. The company continues to pursue additional data center pipeline demand that could be additive to its five-year plan and contribute upside to earnings.
