TXNM: Ascending Triangle detected on 28 Sep 2026

TXNM is forming an ascending triangle at $58.52, bracketed between key support at $58.01 and resistance at $58.71. The pattern shows modest structure (12.5/15), weak breakout momentum (9.0/13), and anemic volume confirmation (7.5/12), yielding an overall score of 61.0 with 54.64% win probability. The measured move target is $60.88, representing a 4.0% move. Volume is tracking below average at 77% of the 20-day mean, while RSI sits neutrally at 60.59—not overbought but lacking decisive breakout conviction. The stock remains 1% below its 52-week high, yet has only gained 3.2% over three months.

TXNM and Blackstone Infrastructure extended their acquisition termination date to May 31, 2027, with closing anticipated in the first half of 2027, pending regulatory approvals including NMPRC and federal sign-off. In July 2026, the PUCT approved TNMP's $2.8 billion rate base settlement with a 9.65% return on equity, with final rates implemented September 13, 2026. On May 29, 2026, PNM filed a 2029-2032 resource portfolio application seeking 800 MW wind, 240 MW solar, 610 MW battery storage, and exit from Four Corners by 2031, addressing projected 40% customer demand growth through 2032. The pattern is forming amid regulatory clarity—near-term rate recovery certainty combined with longer-term M&A execution uncertainty.

A successful breakout above $58.71 resistance would target $60.88 (4.0% move) on the measured-move basis. Volume confirmation is critical—the current 1.45M shares trades 22% below the 20-day average, signaling weak conviction. Historical win probability is 54.64%, barely above a coin flip, meaning breakouts succeed just over half the time. The invalidation level sits at key support of $58.01; a close below this level would negate the setup and suggest a reversal or consolidation extension.

The bearish sector regime (-0.81 score) is a headwind—utilities broadly face headwinds. The Blackstone acquisition, while extended to May 31, 2027, introduces regulatory overhang that could suppress near-term technical performance if approval risks emerge. Volume is a critical weakness: at 77% of average, the breakout lacks institutional participation needed for conviction. With beta of only 0.06, TXNM is deeply defensive, meaning it will underperform in risk-on rallies but may also resist breakout momentum. RSI at 60.59 shows room to run before overbought, but the tight range ($0.70 between support and resistance) offers minimal reward-to-risk. No material earnings catalyst is visible until regulatory filings continue. Short-term pattern quality scores remain modest—structure, volume, and breakout all scored in the bottom half of their ranges.
