TXNM: Ascending Triangle detected on 24 Sep 2026

TXNM is forming an ascending triangle with price consolidating between $58.16 support and $58.70 resistance, just 1.3% below the 52-week high. The pattern structure scores 13.0/15, indicating solid support and resistance definition, but volume (7.5/12) and breakout quality (9.0/13) are modest, reflecting below-average volume confirmation (0.94x relative volume). The overall score of 61.5/98 and win probability of 54.77% suggest a mediocre setup. RSI at 57.88 shows neutral momentum—neither overbought nor oversold. A breakout above $58.70 would target $60.67 conservatively, representing a 3.9% upside move.

TNMP's base rate review was approved on July 30, 2026, with final rates implemented on September 13, 2026, providing recent regulatory tailwind. On May 29, 2026, PNM filed its 2029-2032 Resource Portfolio Application with the NMPRC seeking approval of 800 MW of wind, 240 MW of solar, and 610 MW of battery storage—a major growth catalyst. PNM expects to file its 2026 IRP on or before September 1, 2026. However, TXNM does not plan to issue 2026 earnings guidance during pendency of the proposed Blackstone Infrastructure transaction. The pending $11.5 billion acquisition creates uncertainty, though TNMP is supporting a 28% increase in system peak demand and PNM delivered 80% carbon-free energy in 2025.

A successful breakout above $58.70 resistance would confirm upside momentum toward the conservative target of $60.67, a 3.9% gain. Volume confirmation is required—a daily close above resistance on above-average volume (>1.7M shares) strengthens the signal. The pattern invalidates decisively if price closes below the key support level of $58.16; failure to hold support would suggest a false breakout. With a 54.77% win probability, this is a marginal opportunity—slightly better than a coin flip but lacking the strength of higher-scoring patterns.

Significant regulatory uncertainty clouds this setup: the Blackstone acquisition is progressing through regulatory approval with no 2026 earnings guidance issued. The utilities sector is in bearish regime (score -0.81), creating headwinds. Volume is concerning—at 0.94x relative volume, the pattern lacks conviction and liquidity. Beta of 0.05 shows extremely low volatility, typical for utilities but limiting upside explosive potential. An IRP filing scheduled before September 1, 2026 could trigger volatility. Regulatory rejection or material delays to the Blackstone deal would be major downside catalysts; the company is already pending federal and state approvals after a prior failed Avangrid merger attempt.
