TXNM Energy, formerly known as PNM Resources, is making headlines as it explores a significant acquisition in the U.S. utilities sector. This move comes as infrastructure investors show growing interest in utilities, spurred by surging energy demand from data center expansions, industrial growth, and the electrification of transportation and buildings.
TXNM Energy currently serves over 800,000 customers across New Mexico and Texas, boasting a market capitalization of around $5 billion. As energy needs continue to rise, TXNM is positioning itself to leverage this growth, making it an attractive target for potential buyers.
Negotiations for the deal are currently underway, and while a formal agreement could materialize in the coming weeks, it will be subject to regulatory review and broader market conditions. This cautious approach reflects the complexities of the utilities sector, where regulatory hurdles can significantly impact transaction outcomes.

This isn’t TXNM’s first foray into large-scale acquisitions. In 2020, the company was involved in a proposed $4.3 billion acquisition by Iberdrola’s U.S. subsidiary, Avangrid. However, that deal faced opposition from New Mexico regulators, who blocked it on public interest grounds. Since then, TXNM has been exploring alternative strategic options and has reportedly attracted interest from investment firm KKR.
The potential TXNM deal is part of a broader trend of consolidation in the U.S. power sector. Recent announcements highlight this wave of activity, including NRG Energy‘s $12 billion acquisition of LS Power’s gas generation and demand response platform, CPower. Earlier this year, Constellation Energy Corp. also agreed to acquire Calpine Corp. in a massive $29 billion deal, which includes debt.
As TXNM Energy navigates these negotiations, the outcome could shape the future landscape of the U.S. utilities sector. With rising energy demands and ongoing consolidation, TXNM’s strategic moves will be closely watched by industry stakeholders. The evolving dynamics of the market suggest that this potential acquisition could be a significant step in meeting the energy needs of tomorrow.
