TXNM stock reversal shows New Mexico regulatory process working
New Mexico’s Public Regulation Commission ordered Blackstone Infrastructure and TXNM Energy (parent of Public Service Company of New Mexico) to unwind an unlawful $400 million stock transaction. The companies said they will reverse the deal as required and extend the acquisition timeline while continuing to seek regulatory approval on whether the acquisition is in the public interest.
How this was made

The 30-second read
Why it matters
The newest fact is that TXNM Energy plans to reverse the transaction exactly as ordered, while Blackstone extends the acquisition timeline, keeping the deal alive but extending regulatory and execution uncertainty.
Market read
For traders, the actionable update is the PRC-ordered unwind being implemented, which can affect deal timing, financing needs, and perceived regulatory risk ahead of the PRC’s remaining public-interest review.
What to watch
The article does not quantify the financial cost or timing of the unwind, nor does it provide new details on the PRC’s pending public-interest evaluation, which could dominate the ultimate outcome.
Background
New Mexico’s Public Regulation Commission voted to require Blackstone Infrastructure and TXNM Energy to unwind an unlawful $400 million stock transaction tied to acquiring the parent of Public Service Company of New Mexico.
Ticker impact
The PRC required TXNM Energy to unwind an unlawful $400 million stock transaction, and TXNM says it will reverse it before continuing acquisition review.
Near-term volatility risk around deal timing and regulatory uncertainty; longer-term direction depends on PRC public-interest review outcome.
The article describes a specific PRC-ordered corrective action (unwind) and an announced reversal plan, which is a concrete catalyst for deal mechanics and perceived regulatory risk.
