TXNM Energy's stock experienced a significant pre-market surge of 5.26% on Monday, driven by a positive analyst rating from Mizuho Securities. The energy company's shares were boosted after analyst Anthony Crowdell reiterated a "Hold" rating, reflecting confidence in the company's growth prospects.

While a "Hold" rating may not seem overly bullish, Crowdell's analysis highlighted TXNM Energy's strong capital expenditure growth and favorable market valuation. These factors likely contributed to the pre-market rally, as investors responded positively to the analyst's assessment.

TXNM Energy's pre-market gains suggest that investors are optimistic about the company's future performance, buoyed by the analyst's endorsement of its growth strategy and financial positioning. However, the extent to which the stock can sustain its momentum during regular trading hours remains to be seen.
