Industry Context

This merger represents a significant consolidation within the U.S. regulated utility sector, creating a larger, more geographically diverse entity. The trend towards larger utilities often aims to achieve economies of scale, enhance operational efficiency, and improve access to capital for infrastructure investments, particularly in the context of energy transition and grid modernization. The focus on a "pure-play utility platform" across contiguous states suggests a strategy to leverage regional synergies and regulatory consistency.

Comparison to Industry Standards

• The combined entity's estimated 2024 rate base of $11.4 billion positions it as a substantial regional player, though still smaller than national giants like NextEra Energy (over $70 billion rate base) or Duke Energy (over $60 billion rate base).
• The combined customer base of 2.14 million is comparable to mid-sized regional utilities such as Evergy (1.6 million customers) or Avangrid (3.3 million customers), indicating a significant footprint in its service territories.
• The 61% electric and 39% gas rate base mix is typical for diversified utilities, balancing different energy sources and customer demands, similar to companies like Xcel Energy or CenterPoint Energy.
• The 2.9 GW of owned generation capacity is a solid base for a regional utility, providing a degree of self-sufficiency, though many larger utilities are increasingly divesting generation or focusing on renewables.
