Summary
New Mexico's largest electric utility and its private equity acquirer face regulatory challenges over the legality of a $400 million stock transaction completed mid-2025. PNM Resources' parent company TXNM Energy Inc. and Blackstone Infrastructure, which announced their $11.5 billion acquisition agreement in 2025, submitted formal responses this week to a state investigation questioning whether the stock sale complied with New Mexico's Public Utilities Act.
The investigation was triggered in February 2026 when New Mexico Attorney General Raúl Torrez and Prosperity Works, an Albuquerque-based anti-poverty nonprofit, filed complaints alleging the $400 million sale violated state law. The Public Utilities Act explicitly requires that stock sales occur "with the prior express authorization of the commission." Neither TXNM nor Blackstone obtained such pre-approval before executing the transaction, according to the complaint. In March, the Public Regulation Commission formally launched an investigation and instructed both parties to provide evidence of compliance by the deadline this week.
TXNM and Blackstone have argued the stock sale was operationally necessary, contending it supported the utility's ongoing operations while the broader merger awaited regulatory approval. This characterization frames the transaction as a routine financing measure rather than a material corporate action requiring commission authorization. However, state regulators must determine whether the transaction's substance and timing—occurring during the pendency of a transformative acquisition—triggers statutory requirements for prior approval.
The stock sale dispute represents a distinct layer of regulatory complexity atop existing opposition to the merger itself. Environmental advocates and other stakeholders have raised concerns throughout procedural filings and public hearings regarding the acquisition's broader implications. The outcome of the PRC investigation could create additional conditions on the merger or force restructuring of prior transactions, adding material uncertainty to the timeline and ultimate feasibility of Blackstone's acquisition of New Mexico's largest utility.
