Black Hills Corporation (BKH) is trading higher as the market continues to reprice merger odds and expected strategic benefits following the April 2, 2026 shareholder votes that approved the all-stock combination with NorthWestern Energy. That approval removed a major gating item and shifted focus to regulatory timelines and potential deal conditions, with the companies still targeting a second-half 2026 close.

On April 2, 2026, shareholders of both Black Hills and NorthWestern Energy approved the merger proposals, a key step toward creating the combined utility planned to be named Bright Horizon Energy Corporation at closing. The transaction still requires federal and state approvals, including FERC and multiple state utility regulators, meaning incremental headlines on procedural schedules, settlements, and approval orders can move the stocks as investors handicap closing risk and timing.

For a regulated utility, deal momentum can matter because the investment case is often built around predictable earnings growth from regulated capital spending and rate recovery. Black Hills previously initiated 2026 adjusted EPS guidance of $4.25 to $4.45 (excluding merger-related costs), and merger progress can amplify optimism around longer-term growth, financing flexibility, and the ability to serve incremental load opportunities such as large customers and data-center demand.
