Summary
The New Mexico Public Regulation Commission has opened a formal investigation into whether Blackstone Infrastructure and TXNM Energy (parent company of the state's largest utility PNM) violated state law by executing a $400 million stock sale without obtaining prior regulatory approval. The transaction, which transferred stock from TXNM to a Blackstone affiliate in June 2025, preceded Blackstone's $11.5 billion acquisition bid for PNM announced the previous May.
According to the New Mexico Department of Justice, the stock sale violated the state Public Utilities Act, which charges the PRC with overseeing equity transactions by utilities. Under state statute, transactions executed without prior approval may be deemed void and of no effect. The timing of the stock transfer—executed one month after the acquisition announcement—prompted questions about whether the private equity firm was attempting to secure a financial position before formal regulatory scrutiny could be applied to the broader acquisition. In recent filings, the state Attorney General Raúl Torrez's office explicitly argued that the stock sale should be declared null and void, while PNM and Blackstone have sought either retroactive approval or a determination that no violation occurred.
PRC hearing examiners issued an order requiring both PNM and the Blackstone affiliate to defend their positions by April 6. The order explicitly states it "initiates a formal investigation" and should not be interpreted as a final determination on the question of legality. Both companies have denied wrongdoing, with a Blackstone spokesperson asserting that the stock sale did not confer control over PNM operations. However, advocacy organizations including Prosperity Works and New Energy Economy characterized the regulatory order as validation of their concerns, with New Energy Economy's executive director Mariel Nanasi calling it "a significant victory for the rule of law and for the people of New Mexico."
The investigation represents a critical juncture in Blackstone's bid to acquire New Mexico's largest utility, as the outcome could impact the broader acquisition's regulatory pathway and establish precedent for how the PRC oversees financial transactions by utilities during pending acquisition proceedings.
