TXNM is a holding company that owns and operates two regulated electric utilities, PNM and TNMP, providing electricity services in New Mexico and Texas. The company serves approximately 844,000 residential, commercial, and industrial customers across its service territories. TXNM’s vision is to create a clean and bright energy future while delivering reliable, affordable, and environmentally responsible power. Its strategy emphasizes safe and reliable operations, utility plant investments, superior customer experience, environmentally responsible power, and active stakeholder and community engagement. In May 2025, TXNM entered into a merger agreement with affiliates of Blackstone Infrastructure, with the transaction expected to close in the second half of 2026 pending regulatory approvals. The company’s operations are guided by core values of safety, caring, and integrity, and it seeks to earn authorized returns on its regulated businesses while maintaining investment grade credit ratings.
TXNM generates revenue primarily through the regulated sale of electricity and related utility services to its customers. PNM, as a vertically integrated utility in New Mexico, earns revenue from electricity generation, transmission, and distribution, with rates approved by the New Mexico Public Regulation Commission and including fuel cost recovery through its FPPAC mechanism. TNMP, operating in Texas’ deregulated market, provides transmission and distribution services to retail electric providers and collects revenue based on tariffs set by the Public Utility Commission of Texas. Additional revenue streams include renewable energy credits, energy efficiency program incentives, and participation in wholesale markets such as the Western Energy Imbalance Market. The company’s revenue is also influenced by regulatory rate cases, legislative measures like HB 5247 in Texas, and the recovery of investments through approved rate riders for grid modernization, transportation electrification, and other initiatives.
The company operates through the following segments:
• PNM: This segment provides electricity generation, transmission, and distribution services as a vertically integrated utility in New Mexico.
• TNMP: This segment provides transmission and distribution services to retail electric providers in Texas under a regulated tariff.
• Corporate and Other: This segment includes holding company functions and shared services that support the utility subsidiaries.
TXNM positions itself as a regulated utility committed to a sustainable energy future while maintaining reliable and affordable service. Its competitive advantages include a proactive grid modernization plan that enhances resilience and integrates distributed generation, a strong focus on customer satisfaction through improved outage communications and assistance programs, and investment grade credit ratings that support cost effective access to capital. The company’s pursuit of a carbon-free generating portfolio by 2040, backed by plans to retire coal-fired units and expand renewable resources, differentiates it from many peers still reliant on fossil fuel generation. While TXNM operates in competitive markets alongside other investor-owned and municipal utilities, its emphasis on sustainability, community engagement, and regulatory collaboration provides a distinct market stance.
TXNM serves a diverse customer base consisting of approximately 844,000 residential, commercial, and industrial accounts in New Mexico and Texas. The residential segment includes single family and multi family homes, while the commercial segment serves businesses ranging from small retailers to large industrial facilities. The industrial segment supports manufacturing, mining, and other energy intensive operations. Notable among its customers is the Meta data center located in PNM’s service territory, which receives electricity under a specialized rate arrangement. Additionally, TXNM provides service to numerous governmental entities, tribal communities, and educational institutions through its standard tariffs and targeted programs such as low-income assistance and renewable energy incentives.

Investment Thesis
▲ Bull case
TXNM Energy's core regulated utilities TNMP and PNM demonstrate robust long-term growth fundamentals driven by structural shifts in energy demand and infrastructure investment, which the market is underestimating amid transaction-focused noise. TNMP's service territory in Texas is experiencing sustained high growth in system demand due to population influx, industrial expansion, and data center proliferation—trends reinforced by Texas legislative initiatives supporting grid reliability and resilience. This is evidenced by TNMP's updated five-year capital investment plan projecting $4.926 billion in expenditures from 2026-2030, with annual spending rising from $762 million in 2026 to a peak of $1.098 billion in 2028 before stabilizing above $1 billion through 2030, reflecting confidence in enduring demand rather than temporary stimulus. Concurrently, PNM's plan allocates $4.94 billion over the same period, with spending accelerating to $1.5 billion in 2029 to support New Mexico's clean energy transition under the Energy Transition Act, including grid modernization, renewable integration, and battery storage projects like the recently approved $78 million for distribution storage at solar facilities. These investments are not speculative but are tied to enforceable state mandates and customer growth forecasts—PNM projects a 40% increase in electricity demand by 2032—creating a durable revenue stream through regulated rate base expansion, which is forecasted to grow from $7.6 billion in 2026 to $13.6 billion by 2030 across both utilities. The market fixates on the Blackstone transaction timing but overlooks that this capital plan was independently developed and approved as part of normal forecasting, meaning growth investments will proceed regardless of transaction outcome, providing downside protection and intrinsic value appreciation through rate base accretion.
The regulatory settlements recently secured by TNMP and PNM reveal hidden earnings stability and de-risked cash flow generation that the market is ignoring due to preoccupation with merger uncertainty. TNMP's comprehensive settlement in its Texas base rate review—approved by the PUCT with broad stakeholder support including Walmart, Data Center Coalition, and municipal groups—locks in a $2.8 billion rate base as of June 30, 2025, preserves the 9.65% ROE and 45% equity ratio, and includes $20.5 million in Hurricane Beryl restoration cost recovery over five years via rate riders, all while offsetting higher O&M costs through depreciation rate adjustments. This settlement, subject only to PUCT approval (with interim rates effective May 22, 2026), ensures predictable earnings without reliance on interim capital mechanisms. Similarly, PNM's NMPRC-approved $165 million economic development projects under New Mexico Senate Bill 170 allow cost deferral until customer benefits materialize, reducing near-term earnings volatility, while its grid modernization plan recovery rider—effective April 15, 2026—secures $7 million in year-one revenue requirement for smart meters and two-way grid communication, directly supporting operational efficiency and outage reduction. These mechanisms create a floor for ongoing earnings, as seen in Q1 2026 where ongoing EPS of $0.21 exceeded GAAP EPS of $0.03 due to excluded non-cash items like unrealized investment losses ($16.9 million) and merger costs ($5.6 million). The market fails to recognize that ongoing earnings power—driven by regulated rate base growth and cost recovery mechanisms—is structurally improving, with TNMP's ongoing Q1 EPS rising to $0.30 from $0.24 year-over-year and PNM's ongoing EPS recovering to $0.01 from a prior-year loss, signaling operational resilience masked by GAAP noise.
TXNM Energy's capital allocation strategy reflects a deliberate shift toward sustainable, customer-funded infrastructure that enhances long-term value creation, a nuance lost in the market's fixation on the Blackstone premium. The company's updated five-year plan prioritizes investments that directly support regulatory objectives: TNMP's spending aligns with Texas legislative grid resilience mandates, while PNM's allocations target clean energy compliance (80% carbon-free in 2025, targeting 100% by 2031), economic development, and grid modernization—all of which are recoverable through regulated rates. This is underscored by the fact that PNM's second phase of its $105 million rate increase (implemented April 1, 2026) explicitly supports wildfire prevention, grid upgrades, and energy storage, and its recent NMPRC approval for 30 MW of distribution battery storage ($78 million) addresses hosting-capacity limits at solar facilities, enabling further renewable integration without costly grid upgrades. Critically, these investments are not discretionary but are driven by enforceable state policies and customer demand growth—PNM's 40% demand forecast by 2032 and TNMP's response to Texas legislative infrastructure bills—meaning they represent inevitable, rate-based capex rather than speculative spending. The market misinterprets the elevated capital plan as financial risk, but in regulated utilities, higher approved rate base directly translates to higher authorized earnings via the ROE applied to rate base; with TNMP and PNM's combined rate base projected to reach $13.6 billion by 2030 (up from $7.6 billion in 2026) and stable ROEs around 9.65%, the implied earnings power from rate base growth alone could support ongoing EPS expansion independent of transaction outcomes, offering a compounding value driver the market is presently discounting.

TXNM Energy faces material execution risk in completing the Blackstone Infrastructure transaction, which the market is underpricing despite clear regulatory hurdles remaining, creating significant downside if the deal fails to close. While FERC and PUCT have approved the transaction, critical approvals from the Nuclear Regulatory Commission (NRC) and New Mexico Public Regulation Commission (NMPRC) are still pending, and the company's own disclosures explicitly warn that the closing is subject to "satisfaction or waiver of the remaining customary closing conditions," including receipt of these state and federal approvals. The NMPRC, in particular, has historically scrutinized utility transactions for impacts on rates and service quality, and although the Blackstone deal includes ring-fencing commitments, there is no guarantee of timely or unconditional approval—especially given New Mexico's strong regulatory oversight of PNM, which serves as the state's largest electric utility. Furthermore, the safe harbor statements across all recent filings repeatedly highlight risks such as the potential for termination fees, shareholder dissent (despite prior approval), legal challenges from opposition groups, and disruption to management focus during the pendency—all of which could delay or derail the transaction. If the deal collapses, TXNM would not only lose the $61.25 per share premium but could face a severe valuation reset to standalone utility multiples, especially given its ongoing earnings volatility and the market's likely reassessment of its standalone growth prospects without Blackstone's committed capital. The market appears to be pricing in a near-certain close, but the binary nature of this outcome presents asymmetric risk that is not adequately reflected in current valuations.
Underlying operational weaknesses in TXNM's utility operations, particularly at PNM, are being obscured by strong ongoing earnings metrics and transaction optimism, revealing deteriorating fundamentals that could persist regardless of the Blackstone deal's outcome. While ongoing earnings showed resilience in Q1 2026 ($23.8 million vs $18.1 million year-over-year), GAAP earnings collapsed to $3.7 million from $8.9 million, driven by a $16.9 million unrealized loss on investment securities—a figure that has more than doubled from $8.2 million in Q1 2025 and reflects growing exposure to market volatility in the company's investment portfolio. This trend is worsening, as evidenced by the full-year 2025 GAAP net earnings of $151.4 million versus ongoing earnings of $238.9 million, a $87.5 million gap largely attributable to a $58.8 million pension settlement charge and $43.1 million in merger costs—non-recurring items that, while excluded from ongoing earnings, signal underlying balance sheet stress and costly corporate actions. More concerningly, PNM's GAAP performance continues to deteriorate: its ongoing EPS was just $0.01 in Q1 2026 versus $0.09 in Q1 2025, and its GAAP EPS turned negative at ($0.14) versus $0.01 a year earlier, despite ongoing earnings showing stability. This divergence suggests PNM is increasingly reliant on non-core adjustments to mask weak regulated earnings, potentially due to rising O&M costs, regulatory lag in rate case recoveries, or underperformance in its renewable transition initiatives. The market's focus on ongoing earnings ignores that GAAP reflects true economic profitability, and the widening gap between GAAP and ongoing metrics indicates deteriorating core operations that could undermine long-term value even if the transaction closes, as Blackstone would inherit these operational challenges.
TXNM Energy's aggressive capital expenditure plan, while framed as growth-supportive, introduces significant financial risk and potential rate base overhang that the market is overlooking, particularly given the company's declining free cash flow trajectory and reliance on external financing. The consolidated five-year capital plan totals $10.215 billion from 2026-2030, with peak spending of $2.621 billion in 2029—levels that require substantial incremental financing beyond internal cash generation. Although the company cites regulatory recovery mechanisms, the scale of investment implies sustained pressure on cash flows, especially as ongoing earnings growth has been modest: ongoing EPS rose only from $0.19 in Q1 2025 to $0.21 in Q1 2026, a mere 10.5% increase despite massive capex escalation. This imbalance is exacerbated by the fact that TNMP and PNM's rate base growth forecasts ($7.6B to $13.6B by 2030) assume timely and full recovery of all expenditures through rates, but regulatory lag, potential disallowances, or shifting policy environments (e.g., changes in ROE authorization or equity ratio requirements) could delay or impair earnings translation. Worse, the company has already issued shares for $800 million in mid-2025 and another $105 million in March 2026 to fund operations, diluting existing shareholders while deploying capital whose returns are not yet realized. If regulatory recovery falls short of expectations—or if customer growth fails to meet PNM's 40% demand forecast by 2032—the company could be left with stranded assets or sub-optimal returns on its $10.2 billion investment, transforming a growth narrative into a value-destroying overinvestment scenario that the market is currently ignoring in its enthusiasm for the Blackstone premium.
