2. Thesis Layer

• Primary Secular Thesis: AI Infrastructure → Power / Grid / Electrical.
• Role & Directness: TXNM is a direct beneficiary of the power demand surge from data centers. As of the May 2025 earnings call, the company reported a 70.5% year-over-year increase in data center load in 2025 compared to 2024. Management explicitly noted the addition of 70 megawatts in Q1 2025 and an expected increase of another 150 megawatts from existing customers by year-end. This positions TXNM not merely as a passive utility, but as a critical infrastructure enabler for the AI boom.
• Secondary Secular Thesis: Energy Transition & Electrification → Grid & Transmission Modernization.
• Exposure: The company is executing a multi-year capital plan to modernize its grid. Management has committed to investing $750 million by 2030 for TNMP and has updated its Grid Modernization Plan to increase investments from $344 million to $367 million over the first six years. This dual exposure (AI power + Grid modernization) creates a robust structural tailwind, though the AI load growth is the more immediate revenue driver.

3. The Business

TXNM Energy, Inc. is a holding company operating two regulated electric utilities: PNM Resources (serving New Mexico) and TNMP (serving Texas). As of the latest filings, the company serves approximately 842,000 residential, commercial, and industrial customers.

• Revenue & Capital Dynamics:
• Rate Base Growth: The company is actively expanding its rate base to support new infrastructure. In the first quarter of 2025, the system resiliency plan was approved, allowing for the recovery of $546 million in capital improvements.
• Investment Trajectory: Management forecasts a significant ramp-up in capital intensity. Investments are expected to grow from $600 million in the current year to over $1 billion starting in 2028.
• Capacity Needs: The company forecasts a need for at least 500 megawatts of new capacity by 2030, driven by the independent monitoring process and customer demand.
• Regulatory Environment:
• PNM (New Mexico): The NMPRC approved a general rate increase on May 15, 2025. This includes a $105.0 million increase in retail revenues, with the first phase effective July 1, 2025, and the second phase effective April 1, 2026. The approval reflects a Return on Equity (ROE) of 9.45%.
• TNMP (Texas): In November 2025, TNMP filed a Base Rate Review with the PUCT requesting recovery of $2.8 billion of rate base, seeking an ROE of 10.4%.
• Merger Context: A merger agreement with Blackstone Infrastructure affiliates was signed on May 18, 2025. As of the February 2026 filing, the merger is expected to close in the second half of 2026, following a unanimous settlement with the PUCT on December 11, 2025.

4. Archetype and Conviction

• Archetype: Defensive Operator.
• Fit: TXNM fits the "Defensive Operator" archetype due to its regulated revenue model, which provides predictable cash flows and protection against economic downturns, combined with a clear, management-guided path to growth via capital expenditure.
• Conviction Stack:
• Thesis Strength: High. The convergence of AI-driven load growth and regulatory approval for rate increases provides a clear revenue visibility.
• Evidence Quality: Strong. The evidence base includes specific earnings transcripts (May 2025) and SEC filings (Feb 2026, May 2026) confirming rate approvals, capital plans, and load growth.
• Structural Quality: Moderate to High. The company is executing a "growth at a reasonable price" model within a regulated framework. The transition from $600M to >$1B in annual capex signals a shift from maintenance to expansion.
• Setup Readiness: Low (Technical). The current price of $57.06 with a sub-threshold ATR of 0.8% suggests the market is not yet pricing in a breakout. The setup is fundamentally sound but technically dormant.
• Rerating Potential: Moderate. The potential for a higher ROE (10.4% requested for TNMP vs. 9.45% approved for PNM) and the successful closure of the Blackstone merger could provide a valuation re-rating catalyst in the second half of 2026.

5. Invalidation, Strengthening, and Gaps

• What Would Invalidate:
• Regulatory Rejection: If the PUCT denies the TNMP rate base recovery request or significantly lowers the approved ROE below the requested 10.4%, the investment thesis regarding capital recovery would be weakened.
• Merger Failure: If the Blackstone Infrastructure merger does not close in the second half of 2026 as expected, or if financing conditions (though currently stated as non-existent) emerge, the strategic direction could shift.
• Load Stagnation: A significant slowdown in data center load growth (e.g., failure to add the projected 150 MW) would undermine the primary secular thesis.
• What Would Strengthen:
• Successful Merger Close: Confirmation of the merger closing in H2 2026 would validate the strategic partnership and likely unlock further capital efficiency.
• Accelerated Rate Recovery: If the PUCT approves the TNMP request with a higher ROE or faster implementation, it would directly boost earnings per share (EPS) guidance.
• New Data Center Announcements: Public announcements of new major data center projects in the service territories would validate the 500 MW capacity need forecast.
• Gaps in Evidence:
• Post-Merger Integration Plan: While the merger is expected to close, specific details on how the Blackstone partnership will alter the capital allocation strategy post-closing are not detailed in the provided evidence.
• 2026 Full-Year Guidance: The most recent earnings transcript is from May 2025. Specific full-year 2026 guidance or updated EPS targets for the current period (June 2026) are not explicitly provided in the evidence block, though the 2025 guidance ($2.74–$2.84) remains the anchor.

PRIVATE ANALYST CALL

Judgment: Buy Confidence: medium Key evidence: 70.5% year-over-year increase in data center load in 2025; NMPRC approval of $105M rate increase for PNM with 9.45% ROE; Merger with Blackstone Infrastructure expected to close in H2 2026. Key risks: Regulatory rejection of TNMP rate base recovery request; potential delays in the Blackstone merger closing; sub-threshold volatility (0.8% ATR) indicating lack of immediate price momentum. Sizing hint: Position size should reflect the defensive nature of the utility but be tempered by the technical lack of a confirmed breakout signal. Expected path: Management expects the merger to close in H2 2026, followed by the implementation of the second phase of the PNM rate increase in April 2026 and continued capital deployment toward the $1B+ annual capex target starting in 2028. Expected horizon: 12 to 18 months for the merger and rate implementation cycle to fully reflect in financials. Failure mode to watch: The PUCT denying the TNMP rate base recovery request or significantly reducing the approved ROE below the 10.4% target.
