$11.5B acquisition positions TXNM Energy for long-term clean energy growth in New Mexico and Texas.
Customer protections remain intact: State-regulated rates, local management, and labor agreements preserved.
Blackstone funds deal with equity only, signaling financial discipline and confidence in infrastructure returns.
Blackstone Infrastructure has announced it will acquire TXNM Energy for $61.25 per share in cash, valuing the company at $11.5 billion, including net debt and preferred stock. The deal underscores growing investor appetite for stable, long-horizon infrastructure assets in high-growth U.S. energy markets.
TXNM Energy operates through subsidiaries PNM and TNMP, serving customers across New Mexico and Texas. The capital injection from Blackstone is expected to accelerate infrastructure investments, enabling both utilities to expand grid resilience and support clean energy transitions in their regions.
“Our successes at TXNM Energy have stemmed from a deliberate approach to investing in PNM and TNMP in a manner aligned with the priorities of our customers and communities,” said Pat Collawn, Chair and CEO of TXNM Energy. “We are excited to form this long-term partnership with Blackstone Infrastructure to build upon these successes.”
Key Terms of the Deal
Shareholders will receive $61.25 per share, a 23% premium to TXNM’s 30-day VWAP prior to the March 5, 2025 news leak.
No new debt will be used to fund the transaction; Blackstone will fully finance with equity, highlighting its long-term commitment and investment-grade approach.
An additional $400 million private equity placement at $50/share will support TXNM’s aggressive growth pipeline.
“We are long-term investors who back industry-leading companies using our perpetual capital to support economic development,” said Sean Klimczak, Global Head of Blackstone Infrastructure. “We look forward to creating win-win, growth-oriented investments across both states.”
Continued Local Control and Community Focus
The agreement emphasizes stability:
PNM and TNMP will remain locally managed, headquartered in New Mexico and Texas.
No job losses are expected; all union agreements will be honored.
Customers’ rates will stay regulated by state commissions (NMPRC and PUCT).
Stakeholder engagement will guide future commitments, with details to be submitted in regulatory filings by fall 2025.
