Most Popular Narrative: 3.1% Undervalued
With TXNM Energy last closing at $58.88 versus a narrative fair value around $60.79, the widely followed view suggests a small valuation gap that hinges on future growth and regulation playing out as expected.
Approval and timely cost recovery of over $546 million in capital improvements through resiliency plans and transmission upgrades will boost the regulated rate base, driving predictable increases in EBITDA and net income via scheduled rate hikes.
Legislative support for prebuilding infrastructure and the introduction of rate mechanisms (like the unified tracker and resilience recovery tools) will reduce regulatory lag, improve earnings stability, and mitigate risks from large capital deployment, supporting earnings growth.
Curious what kind of revenue path and margin lift would need to line up for that valuation to hold? The narrative leans on steady top line progress, fatter profitability, and a future earnings multiple that has to stay supportive. The specific mix behind that fair value might surprise you.
Result: Fair Value of $60.79 (UNDERVALUED)

However, that story can change quickly if regulatory decisions limit cost recovery on large grid projects, or if extreme weather and wildfire risks hit earnings and cash flow harder than expected.

Another View: DCF Flips The Story
While the narrative fair value of $60.79 points to a 3.1% undervaluation, the SWS DCF model paints a very different picture. On this approach, TXNM at $58.88 sits well above an estimated future cash flow value of $33.64, which screens as overvalued instead of cheap.
For you as an investor, that gap highlights a key tension. One framework leans on earnings and multiples, the other on cash flows, and they are not pointing in the same direction. Which set of assumptions do you trust more for a regulated utility facing heavy grid investment and regulatory oversight?
Look into how the SWS DCF model arrives at its fair value.
