NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(1) Significant Accounting Policies and Responsibility for Financial Statements
Financial Statement Preparation
In the opinion of management, the accompanying unaudited interim Condensed Consolidated Financial Statements reflect all normal and recurring accruals and adjustments that are necessary to present fairly the consolidated financial position at September 30, 2024 and December 31, 2023, and the consolidated results of operations, comprehensive income, and cash flows for the nine months ended September 30, 2024 and 2023. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could ultimately differ from those estimated. Weather causes the Company’s results of operations to be seasonal in nature and the results of operations presented in the accompanying Condensed Consolidated Financial Statements are not necessarily representative of operations for an entire year.
On August 2, 2024, PNM Resources, Inc. (“PNMR”) amended its Articles of Incorporation to change its name to TXNM Energy, Inc. (“TXNM”) and increase the number of authorized shares of the Company’s common stock from 120,000,000 to 200,000,000. The Notes to Condensed Consolidated Financial Statements include disclosures for TXNM, PNM, and TNMP. This report uses the term “Company” when discussing matters of common applicability to TXNM, PNM, and TNMP. Discussions regarding only TXNM, PNM, or TNMP are so indicated. Certain amounts in the 2023 Condensed Consolidated Financial Statements and Notes thereto have been reclassified to conform to the 2024 financial statement presentation.
These Condensed Consolidated Financial Statements are unaudited. Certain information and note disclosures normally included in the annual audited Consolidated Financial Statements have been condensed or omitted, as permitted under the applicable rules and regulations. Readers of these financial statements should refer to TXNM’s, PNM’s, and TNMP’s audited Consolidated Financial Statements and Notes thereto that are included in their respective 2023 Annual Reports on Form 10-K.
GAAP defines subsequent events as events or transactions that occur after the balance sheet date but before financial statements are issued or are available to be issued. Based on their nature, magnitude, and timing, certain subsequent events may be required to be reflected at the balance sheet date and/or required to be disclosed in the financial statements. The Company has evaluated subsequent events accordingly.
Principles of Consolidation
The Condensed Consolidated Financial Statements of each of TXNM, PNM, and TNMP include their accounts and those of subsidiaries in which that entity owns a majority voting interest. PNM also consolidates Valencia and ETBC I. See Note 6. PNM owns undivided interests in several jointly-owned power plants and records its pro-rata share of the assets, liabilities, and expenses for those plants. The agreements for the jointly-owned plants provide that if an owner were to default on its payment obligations, the non-defaulting owners would be responsible for their proportionate share of the obligations of the defaulting owner. In exchange, the non-defaulting owners would be entitled to their proportionate share of the generating capacity of the defaulting owner. There have been no such payment defaults under any of the agreements for the jointly-owned plants.
PNMR Services Company expenses, which represent costs that are primarily driven by corporate level activities, are charged to the business segments. These services are billed at cost and are reflected as general and administrative expenses in the business segments. Other significant intercompany transactions between TXNM, PNM, and TNMP include interest and income tax sharing payments, as well as equity transactions. See Note 15. All intercompany transactions and balances have been eliminated.
Dividends on Common Stock
Dividends on TXNM’s common stock are declared by the Board. The timing of the declaration of dividends is dependent on the timing of meetings and other actions of the Board. This has historically resulted in dividends attributable to the second quarter of each year being declared through the actions of the Board during the third quarter of the year. The Board declared dividends on common stock considered to be for the second quarter of $0.3875 per share in July 2024 and $0.3675 per share in August 2023, which are reflected as being in the second quarter within the Dividends Declared per Common Share on the TXNM Condensed Statement of Earnings. The Board declared dividends on common stock for the third quarter of $0.3875

TXNM did not make any cash equity contributions to TNMP in the three and nine months ended September 30, 2024. TXNM made zero and $55.0 million cash equity contributions to PNM in the three and nine months ended September 30, 2024. TXNM did not make any cash equity contributions to TNMP or PNM in the three and nine months ended September 30, 2023. Neither PNM nor TNMP declared or paid any cash dividends on their common stock to TXNM in the three and nine months ended September 30, 2024 and 2023.
New Accounting Pronouncements
Information concerning recently issued accounting pronouncements that have not yet been adopted by the Company is presented below. The Company does not expect difficulty in adopting these standards by their required effective dates.
Accounting Standards Update 2023-07 - Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures
In November 2023, the FASB issued ASU 2023-07 enhancing disclosures about significant segment expenses. Disclosure requirements of this update include disclosure, on an annual and interim basis, of significant segment expenses that are regularly provided to the Chief Operating Decision Maker (“CODM”) and included within each reported measure of segment profit or loss (collectively referred to as the “significant expense principle”); an amount for other segment items by reportable segment and a description of its composition; the title and position of the CODM and an explanation of how the CODM uses the reported measures in assessing segment performance and deciding how to allocate resources; and that a single reportable segment provides all the disclosures required by the amendments in this ASU and all existing segment disclosures in Topic 280. The amendment also clarifies that in addition to the measure most consistent with the measurement principles under GAAP, reporting of additional measures of a segment’s profit or loss used by the CODM in assessing segment performance and determining allocation of resources is allowed. ASU 2023-07 is effective for the Company for annual periods beginning January 1, 2024 and interim periods beginning January 1, 2025 with early adoption being permitted. ASU 2023-07 is to be applied retrospectively to all prior periods presented in the financial statements.
Accounting Standards Update 2023-09 - Income Taxes (Topic 740): Improvements to Income Tax Disclosures
In December 2023, the FASB issued ASU 2023-09 enhancing the transparency and decision usefulness of income tax disclosures. Disclosure requirements of this update include (on an annual basis) the disclosure of specific categories in the rate reconciliation and the inclusion of additional information for reconciling items that meet a quantitative threshold (if the effect of the reconciling item is equal to or greater than 5 percent of the amount computed by multiplying pre-tax income by the applicable statutory rate). The amendment also requires the disclosure (on an annual basis) of information about income taxes paid (net of refunds) including the disaggregation by federal, state, and foreign taxes as well as by individual jurisdiction. Additional requirements include the disclosure of income (loss) from continuing operations before income tax expense (benefit) disaggregated between foreign and domestic as well as income tax expense (benefit) from continuing operations disaggregated by federal, state, and foreign. ASU 2023-09 is effective for the Company beginning January 1, 2025 with early adoption being permitted. ASU 2023-09 is to be applied on a prospective basis with retrospective application permitted.

Non-GAAP Financial Measures
The Company defines utility margin as electric operating revenues less cost of energy. Cost of energy consists primarily of fuel and purchase power costs for PNM and costs charged by third-party transmission providers for TNMP. The Company believes that utility margin provides a more meaningful basis for evaluating operations than electric operating revenues since substantially all such costs are offset in revenues as fuel and purchase power costs are passed through to customers under PNM’s FPPAC and third-party transmission costs are passed on to consumers through TNMP’s transmission cost recovery factor. Utility margin is not a financial measure required to be presented and is considered a non-GAAP measure. PNM and TNMP do not intend for utility margin to represent any financial measure as defined by GAAP. However, the calculation of utility margin, as presented, most closely compares to gross margin as defined by GAAP. Reconciliations between utility margin and gross margin are presented below.

The Condensed Consolidated Statements of Earnings include pre-tax amounts reclassified from AOCI related to Unrealized Gains on Available-for-Sale Debt Securities in gains (losses) on investment securities, related to Pension Liability Adjustment in other (deductions), and related to Fair Value Adjustment for Cash Flow Hedges in interest charges. The income tax impacts of all amounts reclassified from AOCI are included in income taxes in the Condensed Consolidated Statements of Earnings.
(4) Earnings Per Share
Basic earnings per share is computed by dividing net earnings attributable to TXNM by the weighted average number of common shares outstanding during the period. Diluted earnings per share was computed by dividing net earnings attributable to TXNM by the diluted weighted average number of common shares outstanding during the period. Diluted earnings per share reflect the potential dilution that could occur if securities or other agreements to issue common stock were settled. TXNM applies the treasury stock method for restricted stock, the 2023 Forward Sale Agreements, and the 2024 Forward Sale Agreements. The if-converted method is applied in determining the potential dilutive effect of the conversion of outstanding Convertible Notes. For the three and nine months ended September 30, 2024, the Convertible Notes were excluded from the calculation of diluted EPS because the effects were antidilutive. Information regarding the computation of earnings per share is as follows:

(5) Electric Operating Revenues
TXNM is an investor-owned holding company with two regulated utilities providing electricity and electric services in New Mexico and Texas. TXNM’s electric utilities are PNM and TNMP. Additional information concerning electric operating revenue is contained in Note 4 of the Notes to Consolidated Financial Statements in the 2023 Annual Reports on Form 10-K.
Accounts Receivable and Allowance for Credit Losses
Accounts receivable consists primarily of trade receivables from customers. In the normal course of business, credit is extended to customers on a short-term basis. The Company estimates the allowance for credit losses on trade receivables based on historical experience and estimated default rates. Accounts receivable balances are reviewed monthly, adjustments to the allowance for credit losses are made as necessary and amounts that are deemed uncollectible are written off. In addition to the allowance for credit losses on trade receivables, the Company has evaluated other receivables for potential credit related losses. These balances include potential exposures for other non-retail utility services. In the three and nine months ended September 30, 2024 and 2023, there were no estimated credit losses related to these transactions.
Contract Balances
Performance obligations related to contracts with customers are typically satisfied when the energy is delivered and the customer or end-user utilizes the energy. Accounts receivable from customers represent amounts billed, including amounts under ARPs. For PNM, accounts receivable reflected on the Condensed Consolidated Balance Sheets, net of allowance for credit losses, includes $103.1 million at September 30, 2024 and $93.6 million at December 31, 2023 resulting from contracts with customers. All of TNMP’s accounts receivable results from contracts with customers.

Contract assets are an entity’s right to consideration in exchange for goods or services that the entity has transferred to a customer when that right is conditioned on something other than the passage of time (for example, the entity’s future performance). Upon the completion of the Western Spirit Line, PNM entered into a Transmission Service Agreement (“TSA”) with Pattern Wind under an incremental tariff rate approved by FERC. The terms of the agreement provide for a financing component that benefits the customer. As such, the revenue that PNM recognizes will be in excess of the consideration received at the beginning of the service term resulting in a contract asset. The balance of the contract asset is $29.6 million at September 30, 2024 and $22.1 million at December 31, 2023. This contract asset is presented in Other deferred charges on the Condensed Consolidated Balance Sheets.
Contract liabilities arise when consideration is received in advance from a customer before satisfying the performance obligations. Therefore, revenue is deferred and not recognized until the obligation is satisfied. Other utilities pay PNM and TNMP in advance for the joint-use of their utility poles. These revenues are recognized over the period of time specified in the joint-use contract, typically for one calendar year. Deferred revenues on these arrangements are recorded as contract liabilities. TXNM’s, PNM’s, and TNMP’s contract liabilities and related revenues are not material for any of the periods presented. The Company has no other arrangements with remaining performance obligations to which a portion of the transaction price would be required to be allocated.

Increases in revenue in 2024 compared to 2023, resulted from refunds under the SJGS abandonment settlement agreement recorded in 2023 (Note 12).
(6) Variable Interest Entities
How an enterprise evaluates and accounts for its involvement with variable interest entities focuses primarily on whether the enterprise has the power to direct the activities that most significantly impact the economic performance of a VIE. This evaluation requires continual reassessment of the primary beneficiary of a VIE. Additional information concerning PNM’s VIEs is contained in Note 10 of the Notes to Consolidated Financial Statements in the 2023 Annual Reports on Form 10-K.
Valencia
PNM has a PPA to purchase all of the electric capacity and energy from Valencia, a 155 MW natural gas-fired power plant near Belen, New Mexico, through May 2028. A third party built, owns, and operates the facility while PNM is the sole purchaser of the electricity generated. PNM is obligated to pay fixed operation and maintenance and capacity charges in addition to variable operation and maintenance charges under this PPA. For the three and nine months ended September 30,

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

2024, PNM paid $5.2 million and $15.3 million for fixed charges and $1.5 million and $2.0 million for variable charges. For the three and nine months ended September 30, 2023, PNM paid $5.1 million and $15.2 million for fixed charges and $1.4 million and $4.1 million for variable charges. PNM does not have any other financial obligations related to Valencia. The assets of Valencia can only be used to satisfy its obligations and creditors of Valencia do not have any recourse against PNM’s assets. During the term of the PPA, PNM has the option, under certain conditions, to purchase and own up to 50% of the plant or the VIE. The PPA specifies that the purchase price would be the greater of 50% of book value reduced by related indebtedness or 50% of fair market value.
PNM sources fuel for the plant, controls when the facility operates through its dispatch, and receives the entire output of the plant, which factors directly and significantly impact the economic performance of Valencia. Therefore, PNM has concluded that the third-party entity that owns Valencia is a VIE and that PNM is the primary beneficiary of the entity since PNM has the power to direct the activities that most significantly impact the economic performance of Valencia and will absorb the majority of the variability in the cash flows of the plant. As the primary beneficiary, PNM consolidates Valencia in its financial statements. Accordingly, the assets, liabilities, operating expenses, and cash flows of Valencia are included in the Condensed Consolidated Financial Statements of PNM although PNM has no legal ownership interest or voting control of the VIE. The assets and liabilities of Valencia are set forth below and are not shown separately on the Condensed Consolidated Balance Sheets. The owner’s equity and net income of Valencia are considered attributable to non-controlling interest.
Summarized financial information for Valencia is as follows:

Westmoreland San Juan Mining, LLC
As discussed in the subheading Coal Supply in Note 11, PNM and Westmoreland San Juan Mining, LLC (“WSJ LLC”), a subsidiary of Westmoreland Mining Holdings, LLC have agreements under which CCR disposal and mine reclamation services for SJGS will be provided.
TXNM issued $30.3 million in letters of credit to facilitate the issuance of reclamation bonds. The letters of credit support results in TXNM having a variable interest in WSJ LLC since TXNM is subject to possible loss in the event performance by TXNM is required under the letters of credit support. TXNM considers the possibility of loss under the letters of credit support to be remote since the purpose of posting the bonds is to provide assurance that WSJ LLC performs the required reclamation of the mine site in accordance with applicable regulations and the reclamation services agreement provides WSJ LLC the ability to recover the cost of reclamation. Additionally, much of the mine reclamation activities have been and will continue to be performed after the SJGS CSA expired on September 30, 2022. As discussed in Note 11, each of the SJGS participants has established and actively fund trusts to meet future reclamation obligations.

WSJ LLC is considered a VIE. TXNM’s analysis of its arrangements with WSJ LLC concluded that WSJ LLC has the ability to direct its reclamation services, which are the factors that most significantly impact the economic performance of WSJ LLC. Other than PNM being able to monitor reclamation activities, the reclamation services were solely under the control of WSJ LLC, including developing reclamation plans, hiring of personnel, and incurring operating and maintenance expenses. Neither TXNM nor PNM has any ability to direct or influence the reclamation activities. PNM’s involvement through the reclamation services agreement is a protective right rather than a participating right and WSJ LLC still has the power to direct the activities that most significantly impact the economic performance of WSJ LLC. If WSJ LLC performs reclamation services more efficiently than anticipated, its economic performance will improve. Conversely, if WSJ LLC does not perform reclamation services as efficiently as anticipated, its economic performance will be negatively impacted. Accordingly, TXNM believes WSJ LLC is the primary beneficiary and, therefore, WSJ LLC is not consolidated by either TXNM or PNM. The amounts outstanding under the letters of credit support continue to be TXNM’s maximum exposure to loss from the VIE at September 30, 2024.
ETBC I
ETBC I is a wholly-owned, special purpose, subsidiary of PNM that was formed in August 2023 for the limited purpose of purchasing, owning, and administering energy transition property, issuing Securitized Bonds, and performing related activities authorized by the NMPRC. On November 15, 2023, ETBC I issued Securitized Bonds and used the proceeds to purchase energy transition property from PNM. The energy transition property purchased includes the right to impose, bill, collect, and adjust a non-bypassable energy transition charge from all PNM retail customers until the Securitized Bonds are paid in full and all allowed financing costs have been recovered. The Securitized Bonds are secured by the energy transition property and cash collections from the Energy Transition Charges are the sole source of funds to satisfy the debt obligation. The bondholders have no recourse to PNM.
PNM acts as the servicer of the energy transition property on behalf of ETBC I and is responsible for metering, calculating, billing, and collecting the Energy Transition Charges. On behalf of ETBC I, PNM is required to remit all collections of the Energy Transition Charges to the trustee for the Securitized Bonds. PNM has the power to direct the activities that most significantly impact the economic performance of ETBC I and will absorb the majority of the variability in the cash flows of the entity. As the primary beneficiary, PNM consolidates ETBC I in its financial statements. Accordingly, the assets, liabilities, operating expenses, and cash flows of ETBC I are included in the Consolidated Financial Statements of PNM.
The following tables summarize the impact of ETBC I on PNM’s Financial Statements:

(7) Fair Value of Derivative and Other Financial Instruments
Additional information concerning energy related derivative contracts and other financial instruments is contained in Note 9 of the Notes to Consolidated Financial Statements in the 2023 Annual Reports on Form 10-K.
Fair value is defined as the price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Fair value is based on current market quotes as available and is supplemented by modeling techniques and assumptions made by the Company to the extent quoted market prices or volatilities are not available. External pricing input availability varies based on commodity location, market liquidity, and term of the agreement. Valuations of derivative assets and liabilities take into account nonperformance risk, including the effect of counterparties’ and the Company’s credit risk. The Company regularly assesses the validity and availability of pricing data for its derivative transactions. Although the Company uses its best judgment in estimating the fair value of these instruments, there are inherent limitations in any estimation technique.
Energy Related Derivative Contracts
Overview
The primary objective for the use of commodity derivative instruments, including energy contracts, options, swaps, and futures, is to manage price risk associated with forecasted purchases of energy and fuel used to generate electricity, as well as managing anticipated generation capacity in excess of forecasted demand from existing customers. PNM’s energy related derivative contracts manage commodity risk. PNM is required to meet the demand and energy needs of its customers. PNM may be exposed to market risk for the needs of its customers not covered under the FPPAC.
PNM has entered into agreements for the purchase and sale of power from third parties. On April 23, 2024, PNM entered into agreements to purchase a total of 150 MW from July 1, 2024 through July 31, 2024 and 100 MW from August 1, 2024 through August 30, 2024. The agreements were accounted for as derivative agreements and considered economic hedges under the NMPRC approved hedging plan covered by its FPPAC during the second quarter of 2024.
Agreements for the purchase of 85 MW from June through September 2023 as well as agreements for the sale of 50 MW from September 1, 2024 through December 31, 2024 were not considered derivatives because they qualified for a normal purchase, normal sale scope exception.
PNM’s operations are managed primarily through a net asset-backed strategy, whereby PNM’s aggregate net open forward contract position is covered by its forecasted excess generation capabilities or market purchases. PNM could be exposed to market risk if its generation capabilities were to be disrupted or if its load requirements were to be greater than anticipated. If all or a portion of load requirements were required to be covered as a result of such unexpected situations, commitments would have to be met through market purchases. TNMP does not enter into energy related derivative contracts.
Commodity Risk
Marketing and procurement of energy often involve market risks associated with managing energy commodities and establishing positions in the energy markets, primarily on a short-term basis. PNM routinely enters into various derivative instruments such as forward contracts, option agreements, and price basis swap agreements to economically hedge price and

volume risk on power commitments and fuel requirements and to minimize the effect of market fluctuations. PNM monitors the market risk of its commodity contracts in accordance with approved risk and credit policies.
Accounting for Derivatives
Under derivative accounting and related rules for energy contracts, PNM accounts for its various instruments for the purchase and sale of energy, which meet the definition of a derivative, based on PNM’s intent. During the nine months ended September 30, 2024 and the year ended December 31, 2023, PNM was not hedging its exposure to the variability in future cash flows from commodity derivatives through designated cash flow hedges. The derivative contracts recorded at fair value that do not qualify or are not designated for cash flow hedge accounting are classified as economic hedges. Economic hedges are defined as derivative instruments, including long-term power agreements, used to economically hedge generation assets, purchased power and fuel costs, and customer load requirements. Changes in the fair value of economic hedges are reflected in results of operations on the Condensed Consolidated Statements of Earnings and are classified between Electric operating revenues and Cost of energy according to the intent of the hedge. PNM also uses such instruments under an NMPRC approved hedging plan to manage fuel and purchased power costs related to customers covered by its FPPAC. Changes in the fair value of instruments covered by its FPPAC are recorded as Regulatory assets and Regulatory liabilities on the Condensed Consolidated Balance Sheets. The cash impacts of settled derivatives are recorded as operating activities or financing activities on the Condensed Consolidated Statement of Cash Flows consistent with the classification of the hedged transaction. PNM has no trading transactions.
Commodity Derivatives
PNM’s commodity derivative instruments that are recorded at fair value, all of which are accounted for as economic hedges and considered Level 2 fair value measurements, are presented in the following line items on the Condensed Consolidated Balance Sheets:

| Economic Hedges
| September 30, 2024 |  | December 31, 2023
| (In thousands)
Other current assets | $ | — |  |  | $ | 826 |
Other current liabilities | — |  |  | — |
Net | $ | — |  |  | $ | 826 |

Certain of PNM’s commodity derivative instruments in the above table are subject to master netting agreements whereby assets and liabilities could be offset in the settlement process. PNM does not offset fair value and cash collateral for derivative instruments under master netting arrangements and the above table reflects the gross amounts of fair value assets and liabilities for commodity derivatives.
As discussed above, PNM has NMPRC-approved guidelines for hedging arrangements to manage fuel and purchased power costs related to customers covered by its FPPAC. The table above includes no other current assets or other current liabilities related to these arrangements at September 30, 2024 and $0.8 million of other current assets and zero of other current liabilities at December 31, 2023 with changes in fair value recorded as Regulatory assets and Regulatory liabilities.
At September 30, 2024 and December 31, 2023, PNM had no amounts recognized for the legal right to reclaim cash collateral. However, amounts posted as cash collateral under margin arrangements were $0.1 million at September 30, 2024 and $0.2 million at December 31, 2023. These amounts are included in other current assets on the Condensed Consolidated Balance Sheets. At September 30, 2024 and December 31, 2023, obligations to return cash collateral were $0.2 million, which is included in other current liabilities on the Condensed Consolidated Balance Sheets.
The changes in the fair value of commodity derivative instruments that are considered economic hedges had no impact on PNM’s net earnings during the nine months ended September 30, 2024 and 2023. Commodity derivatives had no impact on OCI for any of the periods presented. Commodity contract volume positions are presented in MMBTU for gas related contracts and in MWh for power related contracts.

In connection with managing its commodity risks, PNM enters into master agreements with certain counterparties. If PNM is in a net liability position under an agreement, some agreements provide that the counterparties can request collateral if PNM’s credit rating is downgraded; other agreements provide that the counterparty may request collateral to provide it with “adequate assurance” that PNM will perform; and others have no provision for collateral.
The table below presents information about PNM’s contingent requirements to provide collateral under certain commodity contracts having an objectively determinable collateral provision, that are in net liability positions, and that are not fully collateralized with cash. Contractual liability represents those commodity derivative contracts recorded at fair value on the balance sheet, determined on an individual contract basis without offsetting amounts for individual contracts that are in an asset position and could be offset under master netting agreements with the same counterparty. Cash collateral posted under these contracts does not reflect letters of credit under the Company’s revolving credit facilities that may have been issued as collateral. Net exposure is the net contractual liability for all contracts, including those designated as normal purchase and normal sale, offset by existing collateral and by any offsets available under master netting agreements, including both assets and liability positions. At September 30, 2024 and December 31, 2023, PNM had zero contractual liability, zero posted cash collateral, and no such contracts in a net liability position.
Non-Derivative Financial Instruments
The carrying amounts reflected on the Condensed Consolidated Balance Sheets approximate fair value for cash, receivables, and payables due to the short period of maturity. Investment securities are carried at fair value. Investment securities consist of PNM assets held in the NDT for its share of decommissioning costs of PVNGS, a trust for PNM’s share of decommissioning costs at SJGS, and trusts for PNM’s share of final reclamation costs related to the coal mines serving SJGS and Four Corners. See Note 11. At September 30, 2024 and December 31, 2023, the fair value of investment securities included $386.8 million and $361.0 million for the NDT, $5.9 million and $12.3 million for the SJGS decommissioning trust, and $60.8 million and $71.1 million for the coal mine reclamation trusts.
PNM records a realized loss as an impairment for any available-for-sale debt security that has a fair value that is less than its carrying value. At September 30, 2024 and December 31, 2023, PNM had no available-for-sale debt securities for which carrying value exceeded fair value, where the impairments were considered to be “other than temporary” and included in AOCI rather than recognized in earnings. All gains and losses resulting from sales and changes in the fair value of equity securities are recognized immediately in earnings.
Gains and losses recognized on the Condensed Consolidated Statements of Earnings related to investment securities in the NDT, SJGS decommissioning, and coal mine reclamation trusts are presented in the following table:

Fair Value Disclosures
The Company determines the fair values of its derivative and other financial instruments based on the hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair value. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability.
For investment securities, Level 2 fair values are provided by fund managers utilizing a pricing service. For Level 2 fair values, the pricing provider predominantly uses the market approach using bid side market values based upon a hierarchy of information for specific securities or securities with similar characteristics. Fair values of Level 2 investments in mutual funds are equal to net asset value (“NAV”). For commodity derivatives, Level 2 fair values are determined based on market observable inputs, which are validated using multiple broker quotes, including forward price, volatility, and interest rate curves to establish expectations of future prices. Credit valuation adjustments are made for estimated credit losses based on the overall exposure to each counterparty. For the Company’s long-term debt, Level 2 fair values are provided by an external pricing service. The pricing service primarily utilizes quoted prices for similar debt in active markets when determining fair value. Management of the Company independently verifies the information provided by pricing services. Uncategorized investments include common/collective investment trusts, which are measured at NAV at the end of each reporting period. Audited financial statements are received for each fund and reviewed by the Company annually. Fair value for these collective investment trusts is measured using a practical expedient provided under GAAP that allows the NAV per share to be used as fair value for investments in certain entities that do not have readily determinable fair values and are considered to be investment companies. Investments valued using this practical expedient are not required to be presented within the GAAP fair value hierarchy.

(8) Stock-Based Compensation
TXNM has various stock-based compensation programs, which provide restricted stock awards, that are performance based and time based, under the Performance Equity Plan (“PEP”). Although certain PNM and TNMP employees are eligible to participate in the TXNM plans, PNM and TNMP do not have separate employee stock-based compensation plans. Performance stock awards awarded under the PEP are awarded for a three-year, overlapping performance period. Performance stock awards with performance periods ending before 2024 or after 2025 are subject to achieving both performance and market targets. Performance stock awards with performance periods ending from 2024 through 2025 do not include market targets. Other awards of restricted stock are only subject to time-based vesting requirements. Additional information concerning stock-based compensation under the PEP is contained in Note 12 of the Notes to Consolidated Financial Statements in the 2023 Annual Reports on Form 10-K.
Restricted stock under the PEP refers to awards of stock subject to vesting, performance, or market conditions rather than to shares with contractual post-vesting restrictions. Generally, the awards vest ratably over three years from the grant date of the award. However, awards with performance or market conditions vest upon satisfaction of those conditions. In addition, plan provisions provide that upon retirement, participants become 100% vested in certain stock awards. The vesting period for awards of restricted stock to non-employee members of the Board is one-year.
The stock-based compensation expense related to restricted stock awards without performance or market conditions to participants that are retirement eligible on the grant date is recognized immediately at the grant date and is not amortized. Compensation expense for other such awards is amortized over the shorter of the requisite vesting period or the period until the participant becomes retirement eligible. Compensation expense for performance-based shares is recognized ratably over the performance period as required service is provided and is adjusted periodically to reflect the level of achievement expected to be attained. Compensation expense related to market-based shares is recognized ratably over the measurement period, regardless of the actual level of achievement, provided the employees meet their service requirements. At September 30, 2024, TXNM had unrecognized expense related to stock awards of $6.2 million, which is expected to be recognized over an average of 1.6 years.
The grant date fair value for restricted stock and stock awards with internal TXNM performance targets is determined based on the market price of TXNM common stock on the date of the agreements reduced by the present value of future dividends that will not be received prior to vesting. The grant date fair value is applied to the total number of shares that are anticipated to vest, although the number of performance shares that ultimately vest cannot be determined until after the performance periods end. The grant date fair value of stock awards with market targets were determined using Monte Carlo simulation models, which provide grant date fair values that include an expectation of the number of shares to vest at the end of the measurement period.
The following table summarizes the weighted-average assumptions used to determine the awards grant date fair value:

|  | Nine Months Ended September 30,
Restricted Shares and Performance Based Shares |  | 2024 |  | 2023
Expected quarterly dividends per share |  | $ | 0.3875 |  |  | $ | 0.3675 |

Outstanding at September 30, 2024 | 252,920 |  |  | $ | 37.06 |  |  |  |  |

Included, as granted and released, in the table above are 80,492 previously awarded performance-based shares that were earned for the 2021 - 2023 performance measurement period and ratified by the Board in February 2024 (based upon achieving targets at above “target”, below “maximum” levels). Also included, as granted and released, are 7,167 of other RSAs for participants who retired and immediately vested plus a one-time sign-on RSA that immediately vested (discussed below). Excluded from the table above are 143,390, 148,098, and 219,249 shares for the three-year performance periods ending in 2024, 2025 and 2026 that will be awarded if all performance and market criteria are achieved at maximum levels and all executives remain eligible.
On December 4, 2023, the Company entered into retention agreements with its Chairman and Chief Executive Officer and its Senior Vice President and General Counsel under which they would be awarded a total of 26,766 and 8,922, respectively, of restricted stock rights if they remained employed through the award’s vesting date which is the earliest of 24 months from the grant date, the closing of the Merger, or six months following the termination of the Merger. Following the notice from Avangrid regarding the termination of the Merger Agreement as of December 31, 2023, these awards vested on June 30, 2024.
On December 4, 2023, the Company entered into a retention agreement with its President and Chief Operating Officer under which he would receive a retention bonus of $1.0 million to be paid in increments beginning in December 2023 and continuing each December until 2025. On April 8, 2024, pursuant to the retention agreement, the Board elected to convert the unvested portion of the retention bonus of $0.8 million into restricted stock rights whereby each share of restricted stock is equal to one share of Company common stock as of the first trading day after expiration of the then current black-out period. On May 3, 2024, subsequent to the expiration of the black-out period, 19,851 restricted stock rights were awarded that will vest in accordance with the original terms of the retention agreement.
On September 16, 2024, in connection with a one-time sign-on equity grant, the Company’s newly appointed General Counsel, Senior Vice President Regulatory and Public Policy, and Corporate Secretary was awarded 9,300 shares of restricted stock, of which 50% vested immediately and the remaining 50% will vest on the first anniversary of his start date, subject to continued employment through the vesting date.
The following table provides additional information concerning restricted stock activity, including performance-based and market-based shares:

|  | Nine Months Ended September 30,
Restricted Stock |  | 2024 |  | 2023
Weighted-average grant date fair value |  | $ | 33.51 |  |  | $ | 45.00 |
Total fair value of restricted shares that vested (in thousands) |  | $ | 7,976 |  |  | $ | 9,635 |

(9) Financing
The Company’s financing strategy includes both short-term and long-term borrowings. The Company utilizes short-term revolving credit facilities, as well as cash flows from operations, to provide funds for both construction and operating expenditures. Depending on market and other conditions, the Company will periodically sell long-term debt, enter into term loan arrangements, or equity arrangements and use the proceeds to reduce borrowings under the revolving credit facilities or

refinance other debt. Each of the Company’s revolving credit facilities, term loans, and other debt agreements contains a single financial covenant that requires the maintenance of a debt-to-capitalization ratio. For the TXNM agreements, this ratio must be maintained at less than or equal to 70%, and for the PNM and TNMP agreements, this ratio must be maintained at less than or equal to 65%. The Company’s revolving credit facilities, term loans, and other debt agreements generally also contain customary covenants, events of default, cross-default provisions, and change-of-control provisions. PNM must obtain NMPRC approval for any financing transaction having a maturity of more than 18 months. In addition, PNM files its annual informational financing filing and short-term financing plan with the NMPRC. Additional information concerning financing activities is contained in Note 7 of the Notes to Consolidated Financial Statements in the 2023 Annual Reports on Form 10-K.
On May 16, 2023, PNM filed a shelf registration statement that provides for the issuance of up to $650.0 million of SUNs that expires in May 2026.
On March 2, 2022, TXNM filed a shelf registration that provides for the issuance of various types of debt and equity securities. The TXNM shelf registration statement expires in March 2025.
Financing Activities
On May 6, 2024, TXNM entered into a distribution agreement with BofA Securities, Inc., Citigroup Global Markets, Inc., MUFG Securities Americas Inc., RBC Capital Markets, LLC, Scotia Capital (USA) Inc., and Wells Fargo Securities, LLC, as sales agents and Bank of America, N.A., Citibank, N.A., MUFG Securities EMEA plc, Royal Bank of Canada, The Bank of Nova Scotia, and Wells Fargo Bank, N.A., as forward purchasers, pursuant to which the Company may sell, from time to time, up to an aggregate sales amount of $100.0 million of its common stock, no par value, through the sales agents (the “TXNM 2024 ATM Program”). On August 5, 2024, subsequent to approval by shareholders to increase TXNM’s authorized shares, the Company amended the distribution agreement increasing the aggregate sales amount from $100.0 million to $300.0 million of its common stock, no par value, that may be sold under the TXNM 2024 ATM Program.
Sales of the shares made pursuant to the distribution agreement, if any, may be made in “at the market offerings” as defined in Rule 415 of the Securities Act. Actual sales will depend on a variety of factors to be determined by the Company, including (among others) market conditions, the trading price of TXNM’s common stock, capital needs and determinations by the Company of the appropriate sources of funding for the Company. TXNM did not receive any proceeds upon the execution of this agreement. The Company also may enter into forward stock purchase transactions, pursuant to the distribution agreement, in which forward purchasers may borrow from third parties and, through a sales agent acting as a forward seller, sell a number of shares equal to the number of shares of the Company’s common stock to hedge the agreement. Although the Company expects to settle any forward stock purchase transaction with fully physical settlement, except in certain specified circumstances, TXNM has the option to elect physical, cash, or net share settlement of the forward stock purchase transactions. The Company will not receive any proceeds from the sale of borrowed shares of common stock by a forward seller. The Company expects to receive proceeds from the sale of shares directly by sales agents or upon future physical settlement(s) in connection with the forward stock purchase transactions, in which latter case the Company will expect to receive, subject to certain adjustments, aggregate net cash proceeds at settlement equal to the number of shares underlying the relevant forward agreements, multiplied by the relevant forward sale price.
During the second quarter of 2024, TXNM entered into a forward sale agreement with a forward purchaser for the sale of 262,025 shares of common stock under the TXNM 2024 ATM Program (the “Q2 2024 Forward Sale Agreement”). The initial forward sale price of $37.77 per share is subject to adjustments based on a net interest rate factor and by future dividends paid on TXNM common stock as specified in the forward sale agreement.
During the third quarter of 2024, TXNM entered into forward sale agreements with forward purchasers for the sale of 2,196,926 shares of common stock under the TXNM 2024 ATM Program (the “Q3 2024 Forward Sale Agreements”, and together with the Q2 2024 Forward Sale Agreement, the “2024 Forward Sale Agreements”). The Q3 2024 Forward Sale Agreements have a weighted average initial forward sale price of $40.58 per share that is subject to adjustments based on a net interest rate factor and by future dividends paid on TXNM common stock as specified in the forward sale agreement.
TXNM did not initially receive any proceeds upon the execution of these agreements and, except in certain specified circumstances, has the option to elect physical, cash, or net share settlement of the forward sale agreements on or before a date that is 12 months from the agreement effective date. As of September 30, 2024, no shares have been settled under the 2024 Forward Sale Agreements.
On May 10, 2024, PNM entered into a $200.0 million term loan agreement (the “PNM 2024 Term Loan”), among PNM, the lenders party thereto and U.S. Bank National Association, as administrative agent. PNM used the proceeds of the PNM

2024 Term Loan to repay borrowings under the PNM Revolving Credit Facility, the PNM New Mexico Credit Facility, and for general corporate purposes. The PNM 2024 Term Loan bears interest at a variable rate, which was 6.11% at September 30, 2024, and must be repaid on or before November 10, 2025.
On June 10, 2024, TXNM issued $500.0 million aggregate principal amount of junior subordinated convertible notes due 2054 (the “Convertible Notes”) in a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act. The Convertible Notes are unsecured obligations of the Company and rank junior and subordinate in right of payment to the prior payment in full of the Company’s existing and future senior indebtedness. The Convertible Notes bear interest at a rate of 5.75% per year, payable semi-annually in arrears on June 1 and December 1, and mature on June 1, 2054, unless earlier converted, redeemed, or repurchased in accordance with their terms. On June 21, 2024, TXNM issued an additional $50.0 million aggregate principal amount of the Convertible Notes, pursuant to an overallotment option granted by TXNM to the initial purchasers of the $500.0 million Convertible Notes. Proceeds from the Convertible Notes were used to prepay $449.0 million of borrowings under the TXNM 2021 Delayed Draw Term Loan and $90.0 million of borrowings under the TXNM 2023 Term Loan, without penalty, and for other corporate purposes.
TXNM may not redeem the Convertible Notes prior to June 6, 2029, except upon the occurrence of certain tax events, rating agency events or treasury stock events (each, a “special event”). TXNM may redeem for cash all, but not less than all, of the Convertibles Notes upon the occurrence of a special event at any time, at its option, at a redemption price equal to 100% of the principal amount of the Convertible Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. In addition, TXNM may redeem for cash all or part (subject to certain limitations on partial redemptions) of the Convertible Notes, at its option, on or after June 6, 2029, at a redemption price equal to 100% of the principal amount of the convertible notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date, if the last reported sale price of TXNM’s common stock has been at least 130% of the conversion price of the convertible notes then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which TXNM provides notice of redemption. In each case, TXNM will not, and will not be permitted to, issue a notice of redemption, or specify a redemption date, during any interest deferral period.
Prior to the close of business on the business day immediately preceding December 1, 2053, the Convertible Notes will be convertible at the option of the holders only under certain conditions. On or after December 1, 2053 until the close of business on the second business day immediately preceding the maturity date, holders may convert all or any portion of their Convertible Notes at their option, at any time, at the conversion rate then in effect, irrespective of these conditions. Upon conversion of the Convertible Notes, TXNM will pay cash, or deliver an equal aggregate principal amount of a newly issued series of its nonconvertible junior subordinated notes with the same terms as the Convertible Notes (other than the conversion features and certain features in relation to redemption rights), in either case, up to the aggregate principal amount of the Convertible Notes being converted, and deliver shares of TXNM’s common stock in respect of the remainder, if any, of TXNM’s conversion obligation in excess of the aggregate principal amount of the Convertible Notes being converted.
The conversion rate for the Convertible Notes will initially be 22.4911 shares of TXNM’s common stock per $1,000 principal amount of the Convertible Notes, equivalent to an initial conversion price of $44.46 per share of common stock. The initial conversion price of the Convertible Notes represents a conversion premium of 17.5% above the last reported sale price of TXNM’s common stock on June 4, 2024. The conversion rate and the corresponding conversion price will be subject to adjustment by certain events such as increased dividends but will not adjust for any accrued or unpaid interest. In addition, following certain corporate events that occur prior to the maturity date of the Convertible Notes or if TXNM delivers a notice of a special event redemption, TXNM will, in certain circumstances, increase the conversion rate for a holder that elects to convert its Convertible Notes in connection with such a corporate event or such notice of special event redemption, as the case may be.
TXNM issued the Convertible Notes pursuant to an indenture (the “Convertible Notes Indenture”) dated as of June 10, 2024 between TXNM and Computershare Trust Company, N.A., as trustee. The Convertible Notes are subject to continuing compliance with the representations, warranties, and covenants set forth in the Convertible Notes Indenture, which include the customary covenants discussed above. In the event of a fundamental change, as defined in the Convertible Notes Indenture, TXNM may be required to repurchase, for cash, the aggregate principal amount of Convertible Notes plus accrued interest. TXNM may not redeem the Convertible notes prior to June 6, 2029 except upon the occurrence of a special event as defined in the Convertible Notes Indenture.
So long as no event of default with respect to the Convertible Notes has occurred and is continuing, TXNM may, at its option, defer interest payments on the Convertible Notes on one or more occasions for up to 20 consecutive semi-annual

In addition, during any deferral period, interest on deferred interest will accrue at the then-applicable interest rate on the Convertible Notes, compounded semi-annually, to the extent permitted by applicable law.

|  |  |  | Variable Rate |  | Established
Effective Date |  | Maturity Date |  | Debt Hedged |  | Fixed Rate
|  |  |  | (In millions) |  | (Percent)

A fair value gain of $1.8 million is included in Other current assets and a fair value loss of $2.1 million is included in Other deferred credits on the Condensed Consolidated Balance Sheets. The fair value was determined using Level 2 inputs under GAAP, including using forward SOFR curves under the mid-market convention to discount cash flows over the remaining term of the agreements.

The Company presents the service cost component of its net periodic benefit costs in administrative and general expenses and the non-service costs components in other income (deductions), net of amounts capitalized or deferred to regulatory assets and liabilities, on the Condensed Consolidated Statements of Earnings. PNM and TNMP receive a regulated return on the amounts funded for pension and OPEB plans in excess of accumulated periodic cost or income to the extent included in retail rates (a “prepaid pension asset”).
Additional information concerning pension and OPEB plans is contained in Note 11 of the Notes to Consolidated Financial Statements in the 2023 Annual Reports on Form 10-K.

PNM did not make any contributions to its pension plan trust in the three and nine months ended September 30, 2024 and 2023 and does not anticipate making any contributions to the pension plan in 2024 through 2028 based on current law, funding requirements, and estimates of portfolio performance. Funding assumptions were developed using a discount rate of 5.5%. Actual amounts to be funded in the future will be dependent on the actuarial assumptions at that time, including the appropriate discount rate. PNM may make additional contributions at its discretion. PNM did not make any cash contributions to the OPEB trust in the three and nine months ended September 30, 2024 and 2023, however, a portion of the disbursements attributable to the OPEB trust is paid by PNM and are therefore considered to be contributions to the OPEB plan. Payments by PNM on behalf of the PNM OPEB plan were zero and less than $0.1 million for the three and nine months ended September 30, 2024 and were less than $0.1 million and $0.1 million for the three and nine months ended September 30, 2023. These payments are expected to total $0.2 million in 2024 and $10.1 million for 2025-2028. Disbursements under the executive retirement program, which are funded by PNM and considered to be contributions to the plan, were $0.4 million and $0.9 million in the three and nine months ended September 30, 2024 and $0.4 million and $1.0 million in the three and nine months ended September 30, 2023 and are expected to total $1.2 million during 2024 and $4.4 million for 2025-2028.

TNMP did not make any contributions to its pension plan trust in the three and nine months ended September 30, 2024 and 2023 and does not anticipate making any contributions to the pension plan in 2024 through 2027 based on current law, funding requirements, and estimates of portfolio performance. In 2028, TNMP does anticipate making a contribution of $0.2 million based on current law, funding requirements, and estimates of portfolio performance. Funding assumptions were developed using a discount rate of 5.5%. Actual amounts to be funded in the future will depend on the actuarial assumptions at that time, including the appropriate discount rate. TNMP may make additional contributions at its discretion. TNMP did not make any contributions to the OPEB trust in the three and nine months ended September 30, 2024 and 2023 and does not expect to make contributions to the OPEB trust during the period 2024-2028. Disbursements under the executive retirement program, which are funded by TNMP and considered to be contributions to the plan, were zero and less than $0.1 million in the three and nine months ended September 30, 2024 and were zero in the three and nine months ended September 30, 2023 and are expected to total $0.1 million during 2024 and $0.2 million in 2025-2028.

With respect to some of the items listed below, the Company has determined that a loss is not probable or that, to the extent probable, cannot be reasonably estimated. In some cases, the Company is not able to predict with any degree of certainty the range of possible loss that could be incurred. The Company assesses legal and regulatory matters based on current information and makes judgments concerning their potential outcome, giving due consideration to the nature of the claim, the amount and nature of any damages sought, and the probability of success. Such judgments are made with the understanding that the outcome of any litigation, investigation, or other legal proceeding is inherently uncertain. The Company records liabilities for matters where it is probable a loss has been incurred and the amount of loss is reasonably estimatable. The actual outcomes of the items listed below could ultimately differ from the judgments made and the differences could be material. The Company cannot make any assurances that the amount of reserves or potential insurance coverage will be sufficient to cover the cash obligations that might be incurred as a result of litigation or regulatory proceedings. Except as otherwise disclosed, the Company does not expect that any known lawsuits, environmental costs, or commitments will have a material effect on its financial condition, results of operations, or cash flows.
Additional information concerning commitments and contingencies is contained in Note 16 of the Notes to Consolidated Financial Statements in the 2023 Annual Reports on Form 10-K.
Commitments and Contingencies Related to the Environment
Nuclear Spent Fuel and Waste Disposal
Nuclear power plant operators are required to enter into spent fuel disposal contracts with the DOE that require the DOE to accept and dispose of all spent nuclear fuel and other high-level radioactive wastes generated by domestic power reactors. Although the Nuclear Waste Policy Act required the DOE to develop a permanent repository for the storage and disposal of spent nuclear fuel by 1998, the DOE announced that it would not be able to open the repository by 1998 and sought to excuse its performance of these requirements. In November 1997, the DC Circuit issued a decision preventing the DOE from excusing its own delay but refused to order the DOE to begin accepting spent nuclear fuel. Based on this decision and the DOE’s delay, a number of utilities, including APS (on behalf of itself and the other PVNGS owners, including PNM), filed damages actions against the DOE in the Court of Federal Claims. The lawsuits filed by APS alleged that damages were incurred due to DOE’s continuing failure to remove spent nuclear fuel and high-level waste from PVNGS. APS and the DOE entered into a settlement agreement, subsequently extended, that established a process for the payment of claims for costs incurred through December 31, 2025. Under the settlement agreement, APS must submit claims annually for payment of allowable costs. PNM records estimated claims on a quarterly basis. The benefit from the claims is passed through to customers under the FPPAC.
PNM estimates that it will incur approximately $55.6 million (in 2023 dollars) for its share of the costs related to the on-site interim storage of spent nuclear fuel at PVNGS for the remaining term of the operating licenses. PNM accrues these costs as a component of fuel expense as the nuclear fuel is consumed. At September 30, 2024 and December 31, 2023, PNM had a liability for interim storage costs of $12.9 million and $11.0 million, which is included in other deferred credits.
PVNGS has sufficient capacity at its on-site Independent Spent Fuel Storage Installation (“ISFSI”) to store all of the nuclear fuel that will be irradiated during the initial operating license period, which ends in December 2027. Additionally, PVNGS has sufficient capacity at its on-site ISFSI to store a portion of the fuel that will be irradiated during the period of extended operation, which ends in November 2047. If uncertainties regarding the U.S. government’s obligation to accept and store spent fuel are not favorably resolved, APS will evaluate alternative storage solutions that may obviate the need to expand the ISFSI to accommodate all of the fuel that will be irradiated during the period of extended operation.
The Energy Transition Act
In 2019, the Governor signed into New Mexico state law Senate Bill 489, known as the Energy Transition Act (“ETA”). The ETA became effective as of June 14, 2019 and sets a statewide standard that requires investor-owned electric utilities to have specified percentages of their electric-generating portfolios be from renewable and zero-carbon generating resources. The ETA requires utilities operating in New Mexico to have renewable portfolios equal to 40% by 2025, 50% by 2030, 80% by 2040, and 100% zero-carbon energy by 2045. The ETA also allows for the recovery of undepreciated investments and decommissioning costs related to qualifying EGUs that the NMPRC has required be removed from retail jurisdictional rates, provided replacement resources to be included in retail rates have lower or zero-carbon emissions. The ETA requires the NMPRC to review and approve utilities’ annual renewable portfolio plans to ensure compliance with the RPS. Also pursuant to the ETA, the New Mexico Environmental Improvement Board adopted standards of performance that limit CO 2 emissions to no

more than 1,100 lbs. per MWh beginning January 1, 2023 for new and existing coal-fired EGUs with original installed capacities exceeding 300 MW.
The ETA provides for a transition from fossil-fuel generation resources to renewable and other carbon-free resources through certain provisions relating to the abandonment of coal-fired generating facilities. These provisions include the use of energy transition bonds, which are designed to be highly rated bonds that can be issued to finance certain costs of abandoning coal-fired facilities that are retired prior to January 1, 2023 for facilities operated by a “qualifying utility,” or prior to January 1, 2032 for facilities that are not operated by a qualifying utility. The amount of energy transition bonds that can be issued to recover abandonment costs is limited to the lesser of $375.0 million or 150% of the undepreciated investment of the facility as of the abandonment date. Proceeds provided by energy transition bonds must be used only for purposes related to providing utility service to customers and to pay energy transition costs (as defined by the ETA). These costs may include plant decommissioning and coal mine reclamation costs provided those costs have not previously been recovered from customers or disallowed by the NMPRC or by a court order. Proceeds from energy transition bonds may also be used to fund severances for employees of the retired facility and related coal mine and to promote economic development, education and job training in areas impacted by the retirement of the coal-fired facilities. Energy transition bonds must be issued under a NMPRC-approved financing order, are secured by “energy transition property,” are non-recourse to the issuing utility, and are repaid by a non-bypassable charge paid by all customers of the issuing utility. These customer charges are subject to an adjustment mechanism designed to provide for timely and complete payment of principal and interest due under the energy transition bonds.
The ETA also provides that utilities must obtain NMPRC approval of competitively procured replacement resources that shall be evaluated based on their cost, economic development opportunity, ability to provide jobs with comparable pay and benefits to those lost upon retirement of the facility, and that do not exceed emissions thresholds specified in the ETA. In determining whether to approve replacement resources, the NMPRC must give preference to resources with the least environmental impacts, those with higher ratios of capital costs to fuel costs, and those located in the school district of the abandoned facility. The ETA also provides for the procurement of energy storage facilities and gives utilities discretion to maintain, control, and operate these systems to ensure reliable and efficient service.
The ETA has had and will have a significant impact on PNM’s future generation portfolio, including PNM’s retirement of SJGS in 2022. PNM cannot predict the full impact of the ETA with respect to Four Corners or the outcome of its future generating resource abandonment and replacement resource filings with the NMPRC. See additional discussion in Note 12 of PNM’s Four Corners Abandonment Application.
The Clean Air Act
Regional Haze
Pursuant to the CAA, states are required to establish goals for improving visibility in national parks and wilderness areas (also known as Class I areas) and to develop long-term strategies for reducing emissions of air pollutants that cause visibility impairment in their own states and for preventing degradation in other states. States must establish a series of interim goals to ensure continued progress by adopting a new SIP every ten years. In the first SIP planning period, states were required to conduct Best Available Retrofit Technology (“BART”) determinations for certain covered facilities, including utility boilers, built between 1962 and 1977 that have the potential to emit more than 250 tons per year of visibility impairing pollution. For all future SIP planning periods, states must evaluate whether additional emissions reduction measures may be needed to continue making reasonable progress toward natural visibility conditions.
In 2017, EPA published revisions to the regional haze rule in the Federal Register that delayed the due date for the next cycle of SIPs from 2019 to 2021 and altered the planning process that states must employ in determining whether to impose “reasonable progress” emission reduction measures. EPA’s new rule was challenged by numerous parties, but the litigation was held in abeyance after EPA granted various petitions for reconsideration.
In 2018, EPA released a new guidance document on tracking visibility progress for the second planning period. EPA is allowing states discretion to develop SIPs that may differ from EPA’s guidance as long as they are consistent with the CAA and other applicable regulations. In 2019, EPA finalized the draft guidance that was previously released as a companion to the regional haze rule revisions, and EPA clarified that guidance in a memorandum issued in 2021. SIPs for the second planning period were due in July 2021, which deadline NMED was unable to meet. NMED is currently preparing its SIP for the second compliance period and has notified PNM that it will not be required to submit a regional haze four-factor analysis for SJGS since PNM retired its share of SJGS in 2022. On August 30, 2022, EPA published in the Federal Register an official “Finding of Failure to Submit” for states, including New Mexico, that have not yet submitted a round 2 regional haze SIP. This action by

EPA started a 2-year clock for it to issue a Federal Implementation Plan (“FIP”), which deadline has now passed. NMED petitioned the NM Environmental Improvement Board to adopt a proposed SIP and the public hearing of their proposal is scheduled for December 18, 2024. PNM submitted comments on the proposed SIP in response to a request for comments by NMED.
Carbon Dioxide Emissions
In 2015, EPA established standards to limit CO 2 emissions from power plants, including (1) Carbon Pollution Standards for new, modified, and reconstructed power plants; and (2) the Clean Power Plan for existing power plants.
Multiple states, utilities, and trade groups challenged both the Carbon Pollution Standards for new sources and the Clean Power Plan for existing sources in separate cases. Challengers successfully petitioned the US Supreme Court for a stay of the Clean Power Plan. However, before the DC Circuit could issue an opinion regarding either the Carbon Pollution Standards or the Clean Power Plan, the Trump Administration asked that the case be held in abeyance while the rules were reevaluated, which was granted.
In 2019, EPA repealed the Clean Power Plan, promulgated the ACE Rule, and revised the implementing regulations for all emission guidelines. EPA set the BSER for existing coal-fired power plants as heat rate efficiency improvements based on a range of “candidate technologies” that can be applied inside the fence line of an individual facility. The DC Circuit issued an order that granted motions by various petitioners, including industry groups and EPA, to dismiss the cases challenging the Clean Power Plan as moot due to EPA’s issuance of the ACE Rule.
The ACE Rule was also challenged, and on January 19, 2021, the DC Circuit issued an opinion in American Lung Association and American Public Health Association v. EPA, et al., vacating the ACE Rule. While the DC Circuit rejected the ACE Rule, it did not reinstate the Clean Power Plan. Rather, the DC Circuit granted an EPA motion asking the court to withhold issuance of the mandate with respect to the repeal of the Clean Power Plan until EPA responds to the court’s remand in a new rulemaking action.
Numerous parties sought review by the US Supreme Court, and on June 30, 2022, the Court held that the “generation shifting” approach in the Clean Power Plan exceeded the powers granted to EPA by Congress, though the Court did not address the related issue of whether Section 111 of the CAA only authorizes EPA to require measures that can be implemented entirely within the fence line at an individual source. Of broader significance in administrative law, the Court’s opinion expressly invoked the “major question” doctrine, which requires rules involving issues of “vast economic or political significance” to be supported by clear statutory authorization. In cases where there is no clear statement of authority, courts need not defer to the agency’s statutory interpretation on “major questions.” The decision sets legal precedent for future rulemakings by EPA and other federal regulatory agencies whereby the agencies’ authority may be limited based upon similar reasoning.
The litigation over the Carbon Pollution Standards remains held in abeyance but could be reactivated by the parties upon a determination by the court that reconsideration of the rule has concluded.
In 2023, EPA published in the Federal Register proposed regulatory actions under CAA sections 111(b) and (d) to replace the Clean Power Plan and the ACE Rule, and finalized the rules on May 9, 2024. The final rules include revised new source performance standards under Section 111(b) for all new natural gas-fired combustion turbines and emission guidelines under Section 111(d) requiring states to develop standards of performance for GHG emissions from existing fossil-fuel-fired electric steam generating units. In the final rules, EPA determined that the standards for existing coal- or gas-fired steam generating units must be based on the use of either CCS (long-term) or natural gas co-firing (medium-term), or exempt from the rule via early retirement, and the standards for new combustion turbines must be based on CCS (base load), efficient simple cycle design (intermediate load), or lower-emitting fuels (low load). Over a dozen states, several industry groups and some power companies and labor unions have filed challenges to the rule at the DC Circuit. On July 19, 2024, the DC Circuit ruled that petitioners had not met the stringent requirements for a stay of the rules. Attorney generals in 25 states sent an emergency appeal to the US Supreme Court asking it to stay the final rule. On October 16, 2024, the US Supreme Court denied the petitioners’ request for stay. The final rule will remain in effect pending resolution of the ongoing challenges in the DC Circuit and any subsequent appeal to the US Supreme Court. The DC Circuit has scheduled oral argument for December 6, 2024, and indicated that it will decide the challenges during its 2024 term.
Because the CAA 111 rule does not contain provisions for existing natural gas units, on March 26, 2024, EPA announced it was opening a non-regulatory docket and issued framing questions to gather input about ways to design a stronger,

more durable approach to GHG regulation of existing gas combustion turbines. The docket was open for public comment from March 26, 2024 to May 28, 2024 and the agency held a policy forum to bring stakeholders together to share ideas with EPA and others. The agency has indicated that it will re-propose emission guidelines for existing natural gas units in 2024.
In 2021, President Biden signed an extensive Executive Order aimed at addressing climate change concerns domestically and internationally. The order is intended to build on the initial climate-related actions the Biden Administration took on January 20, 2021. It addresses a wide range of issues, including establishing climate change concerns as an essential element of U.S. foreign and security policy, identifying a process to determine the U.S. INDC under the Paris Agreement, and establishing a Special Presidential Envoy for Climate that will sit on the National Security Council. On April 22, 2021, at the Earth Day Summit, as part of the U.S.’s re-entry into the Paris Agreement, President Biden unveiled the goal to cut U.S. emissions by 50% - 52% from 2005 levels by 2030, nearly double the GHG emissions reduction target set by the Obama Administration. The 2030 goal joins President Biden’s other climate goals which include a carbon pollution-free power sector by 2035 and a net-zero emissions economy by no later than 2050.
PNM’s review of the GHG emission reductions standards that have or may occur as a result of legislation or regulation under the Biden Administration is ongoing. We are currently determining what impact, if any, the final rules will have on our business, results of operation, and financial condition.
National Ambient Air Quality Standards (“NAAQS”)
The CAA requires EPA to set NAAQS for pollutants reasonably anticipated to endanger public health or welfare. EPA has set NAAQS for certain pollutants, including NOx, SO 2, ozone, and particulate matter.
NOx Standard – In 2018, EPA published the final rule to retain the current primary health-based NOx standards of which NO 2 is the constituent of greatest concern and is the indicator for the primary NAAQS. EPA concluded that the current 1-hour and annual primary NO 2 standards are requisite to protect public health with an adequate margin of safety. The rule became effective on May 18, 2018. The State of New Mexico has attained the current NOx NAAQS standards.
SO 2 Standard – In 2019, EPA announced its final decision to retain, without changes, the primary health-based NAAQS for SO 2. Specifically, EPA will retain the current 1-hour standard for SO 2, which is 75 parts per billion, based on the 3-year average of the 99th percentile of daily maximum 1-hour SO 2 concentrations.
In 2021, EPA published in the Federal Register the initial air quality designations for all remaining areas not yet designated under the 2010 SO 2 Primary NAAQS. All areas of New Mexico have been designated attainment/unclassifiable through four rounds of designations by EPA.
Ozone Standard – In 2015, EPA finalized the new ozone NAAQS and lowered both the primary and secondary 8-hour standard from 75 to 70 parts per billion. With ozone standards becoming more stringent, fossil-fueled generation units will come under increasing pressure to reduce emissions of NOx and volatile organic compounds since these are the pollutants that form ground-level ozone. On July 13, 2020, EPA proposed to retain the existing ozone NAAQS based on a review of the full body of currently available scientific evidence and exposure/risk information. EPA finalized its decision to retain the ozone NAAQS in a notice published on December 31, 2020 making it immediately effective. In response to lawsuits brought by states and environmental groups, on October 29, 2021, EPA filed a motion in the DC Circuit indicating it will reconsider the 2020 ozone NAAQS. On August 21, 2023, EPA announced an entirely new review of the ozone standard that will incorporate the work to date on the reconsideration, likely indicating a delay in the schedule for a decision on whether the standard should be revised. On January 3, 2024, EPA filed in the DC Circuit an unopposed motion for voluntary remand, without vacatur, of EPA’s final rule retaining the current ozone NAAQS. The filing was made in the consolidated cases challenging the 2020 ozone NAAQS rule.
During 2017 and 2018, EPA released rules establishing area designations for ozone. In those rules, San Juan County, New Mexico, where Four Corners is located, is designated as attainment/unclassifiable and only a small area in Doña Ana County, New Mexico is designated as marginal non-attainment. Although Afton Generating Station is located in Doña Ana County, it is not located within the small area designated as non-attainment for the 2015 ozone standard. The rule became effective May 8, 2018.
NMED has responsibility for bringing the small area in Doña Ana County designated as marginal/non-attainment for ozone into compliance and will look at all sources of NOx and volatile organic compounds. NMED has submitted the required

elements for the Sunland Park Ozone Non-attainment Area SIP. This includes a transportation conformity demonstration, a 2017 baseline emissions inventory and emissions statement, and an amendment to the state’s Non-attainment Permitting rules at 20.2.79 New Mexico Administrative Code to conform to EPA’s SIP Requirements Rule for 2015 Q3 NAAQS (i.e., “implementation rule”).
The SIP elements had staggered deadlines and were done in three submissions: (1) the transportation conformity demonstration was completed by the El Paso Metropolitan Planning Organization on behalf of New Mexico in 2019, which is responsible for transportation planning in that area, and the submission received concurrence from EPA and the Federal Highway Administration; (2) the emissions inventory and statement SIP was submitted to EPA in September 2020; and (3) the Non-attainment New Source Review SIP was submitted to EPA on August 10, 2021. On October 15, 2021, EPA proposed to approve New Mexico’s SIP to meet the emissions inventory and statement requirements of the CAA for the Sunland Park Ozone Non-Attainment Area.
PNM does not believe there will be material impacts to its facilities because of NMED’s non-attainment designation of the small area within Doña Ana County. Until EPA approves attainment designations for the Navajo Nation and releases a proposal to implement the revised ozone NAAQS, PNM is unable to predict what impact the adoption of these standards may have on Four Corners. With respect to EPA’s reconsideration of the 2020 decision to retain the 2015 ozone standards, EPA is statutorily obligated to complete its review of the ozone standards by December 2025. PNM cannot predict the outcome of this matter.
In 2019, EPA issued findings that several states, including New Mexico, had failed to submit interstate transport SIPs for the 2015 8-hour ozone NAAQS, triggering an obligation for EPA to issue a federal implementation plan within two years. In response, NMED submitted a Good Neighbor SIP on July 27, 2021 that demonstrates that there are no significant contributions from New Mexico to downwind problems in meeting the federal ozone standard. Nevertheless, when EPA failed to approve the SIP or issue a FIP within two years of the finding of failure to submit, multiple parties filed a deadline suit against EPA, resulting in a consent decree requiring EPA to issue a FIP or approve a SIP for New Mexico by a deadline of no later than June 1, 2024, which was later extended to August 30, 2024. On March 15, 2023, EPA Administrator Regan signed a final action imposing a FIP on multiple states but did not include a FIP for New Mexico because the most up to date modeling available at proposal confirmed the state did not contribute to downwind ozone nonattainment or maintenance areas. However, the updated modeling EPA used in the final rule indicated that New Mexico may be significantly contributing to one or more non-attainment or maintenance areas. In light of that modeling result, on February 16, 2024, the EPA published a proposed rule partially disapproving the SIPs for New Mexico and four other states (Arizona, Iowa, Kansas, Tennessee) and expanding the Good Neighbor FIP to apply to these states. In denying the NMED-submitted SIP, the EPA concluded that the SIP was incomplete and did not contain the necessary provisions to prohibit emissions from sources within the state from interfering with maintenance of the 2015 ozone NAAQS in downwind areas, specifically a maintenance-only receptor in the El Paso area. The FIP aspect of the proposed rule would require fossil fuel-fired power plants in these five states to participate in an allowance-based ozone season NOx emissions trading program beginning in 2025. Comments on the proposed rule were due May 16, 2024. PNM submitted company-specific comments on the proposal on the due date. EPA is targeting November 2024 for a final rule.
Of importance in considering the possibility of a Good Neighbor FIP for New Mexico, are the many court challenges to EPA’s earlier rulemaking disapproving SIPs and imposing a FIP on 23 states. Numerous courts of appeal have already determined that those challenges are likely to succeed and therefore issued stays of EPA’s SIP disapprovals for about half of the states subject to the FIP. In light of those stays, the US Supreme Court granted a stay of the Good Neighbor FIP on June 27, 2024, and EPA subsequently confirmed the stay applied to all 23 states subject to EPA’s review of the basis for the stay. This court and administrative activity may impact the viability of EPA’s multi-state trading program as to New Mexico. However, on September 4, 2024, EPA sent the final rule for New Mexico and four other states to the Office of Management and Budget indicating EPA plans to move forward with the expansion of the Good Neighbor FIP to New Mexico notwithstanding the stay for the original 23 states. EPA is under a consent decree with environmental non-governmental organizations to issue a final rule which either promulgates a FIP or approves a SIP for New Mexico by November 26, 2024.
PM Standard – In 2023, EPA published, in the Federal Register, a proposal to lower the annual fine PM standard to between 9-10 µg/m3 but retain the rest of its PM standards, including the current daily fine particulate matter standard, the daily coarse particulate matter standard, and the secondary PM standards. The final rule was published on March 6, 2024, lowering the primary annual PM 2.5 NAAQS to 9 ug/m3. The rule is effective May 6, 2024. States will have until March 2032 to attain compliance with the new standard. During the multi-year implementation process, EPA will designate attainment/nonattainment areas by March 6, 2026, and states will submit a State Implementation Plan to EPA by September 6, 2027. This

implementation process also applies to the Albuquerque-Bernalillo County Environmental Health Department who may combine efforts with NMED. Bernalillo County does not currently meet the 9 ug/m3 standard which may impact future air permitting activities at Rio Bravo and Reeves Generating Stations if the county is designated as nonattainment. Beginning May 6, 2024, the new standard became effective for conducting required modeling for permit applications and revisions. Although the lower standard is expected to result in new nonattainment areas throughout the country and could prompt additional PM control requirements, PNM cannot predict the impacts of the outcome of future rulemaking.
Cooling Water Intake Structures
In 2014, EPA issued a rule establishing national standards for certain cooling water intake structures at existing power plants and other facilities under the Clean Water Act to protect fish and other aquatic organisms by minimizing impingement mortality (the capture of aquatic wildlife on intake structures or against screens) and entrainment mortality (the capture of fish or shellfish in water flow entering and passing through intake structures).
To minimize impingement mortality, the rule provides operators of facilities, such as Four Corners, seven options for meeting Best Technology Available (“BTA”) standards for reducing impingement. The permitting authority must establish the BTA for entrainment on a site-specific basis, taking into consideration an array of factors, including endangered species and social costs and benefits. Affected sources must submit source water baseline characterization data to the permitting authority to assist in the determination. Compliance deadlines under the rule are tied to permit renewal and will be subject to a schedule of compliance established by the permitting authority.
In 2018, several environmental groups sued EPA Region IX in the U.S. Court of Appeals for the Ninth Circuit Court over EPA’s failure to timely reissue the Four Corners NPDES permit. The petitioners asked the court to issue a writ of mandamus compelling EPA Region IX to take final action on the pending NPDES permit by a reasonable date. EPA subsequently reissued the NPDES permit. The permit did not contain conditions related to the cooling water intake structure rule, as EPA determined that the facility has achieved BTA for both impingement and entrainment by operating a closed-cycle recirculation system. Several environmental groups filed a petition for review with EPA’s Environmental Appeals Board (“EAB”) concerning the reissued permit. The environmental groups alleged that the permit was reissued in contravention of several requirements under the Clean Water Act and did not contain required provisions concerning certain revised ELG, existing-source regulations governing cooling-water intake structures, and effluent limits for surface seepage and subsurface discharges from coal-ash disposal facilities. EPA withdrew the Four Corners NPDES permit in order to examine issues raised by the environmental groups. Withdrawal of the permit moots the appeal pending before the EAB. EAB thereafter dismissed the environmental groups’ appeal. EPA issued an updated NPDES permit in 2019. The permit was once again appealed to the EAB and was stayed before the effective date. Oral argument was heard on September 3, 2020. The EAB issued an order denying the petition for review on September 30, 2020. The denial was based on the EAB’s determination that the petitioners had failed to demonstrate that review of the permit was warranted on any of the grounds presented in the petition. Thereafter, the Regional Administrator of the EPA signed a notice of final permit decision, and the NPDES permit was issued on November 9, 2020. The permit became effective December 1, 2020 and will expire on November 30, 2025. On January 22, 2021, the environmental groups filed a petition for review of the EAB’s decision with the U.S. Court of Appeals for the Ninth Circuit. The September 2019 permit remains in effect pending this appeal. On March 21, 2022, EPA provided notice in the Federal Register of a proposed settlement agreement with the environmental groups. The parties subsequently executed the settlement agreement as of May 2, 2022. Under the settlement, the associated case was administratively closed through September 6, 2023, during which time a third-party consultant spent 12 months sampling discharges from Four Corners and EPA spent three months completing an analysis. On December 1, 2023, EPA issued a modification, effective December 31, 2023, to the NPDES permit issued on November 9, 2020. The modification applies to permit elements related to effluent discharge. PNM cannot predict whether the analysis under the settlement agreement will result in changes to the NPDES permit but does not anticipate that it will have a material impact on PNM’s financial position, results of operations, or cash flows.
Effluent Limitation Guidelines
In 2013, EPA published proposed revised wastewater ELG establishing technology-based wastewater discharge limitations for fossil fuel-fired electric power plants. EPA signed the final Steam Electric ELG rule in 2015. The final rule, which became effective on January 4, 2016, phased in the new, more stringent requirements in the form of effluent limits for arsenic, mercury, selenium, and nitrogen for wastewater discharged from wet scrubber systems and zero discharge of pollutants in ash transport water that must be incorporated into plants’ NPDES permits. The 2015 rule required each plant to comply between 2018 and 2023 depending on when it needs a new or revised NPDES permit.

The Steam Electric ELG rule was challenged in the U.S. Court of Appeals for the Fifth Circuit by numerous parties. In 2017, EPA signed a notice indicating its intent to reconsider portions of the rule, and the Fifth Circuit issued an order severing the issues under reconsideration and holding the case in abeyance as to those issues. However, the court allowed challenges to other portions of the rule to proceed. In 2019, the Fifth Circuit granted those challenges and issued an opinion vacating several portions of the rule, specifically those related to legacy wastewater and leachate, for which the court deemed the standards selected by EPA arbitrary and capricious.
In 2017, EPA published a final rule for postponement of certain compliance dates. The rule postponed the earliest date on which compliance with the ELG for these waste streams would be required from November 1, 2018 until November 1, 2020. In 2019, EPA published a proposed rule revising the original ELG while maintaining the compliance dates. In 2020, EPA published in the Federal Register the final Steam Electric ELG and Standards for the Steam Electric Power Generating Point Source Category, revising the final 2015 guidelines for both flue gas desulfurization wastewater and bottom ash transport water. The rule requires compliance with new limits as soon as possible on or after October 13, 2021, but no later than December 31, 2025.
In 2021, EPA published notice that it will undertake a supplemental rulemaking to revise the ELG after completing its review of the rules reconsidered in 2020. As part of this process, EPA will determine whether more stringent limitations and standards are appropriate. On March 29, 2023, EPA published the proposed ELG Rule in the Federal Register. The proposed rule includes stricter limitations on bottom ash transport water, flue gas desulfurization, and coal combustion residual leachate. Also included are flexibilities for coal-powered facilities that will soon decommission or repower. With this proposed rule EPA has extended the date of decommissioning or repowering from December 31, 2028, to December 31, 2032. Comments on the proposed rule were due May 30, 2023.
On May 9, 2024, EPA published a final rule to revise ELGs under the Clean Water Act for the Steam Electric Power Generating Point Source Category. This final supplemental rule updates the technology-based ELGs applicable to flue gas desulfurization wastewater, bottom ash transport water, and legacy wastewater at existing sources, and combustion residual leachate at new and existing sources.
Reeves Station discharges cooling tower blowdown to a publicly owned treatment plant and no longer holds an NPDES permit; therefore, it is expected that no requirements will be imposed.
See “Cooling Water Intake Structures” above for additional discussion of Four Corners’ current NPDES permit. Four Corners may be required to change equipment and operating practices affecting boilers and ash handling systems, as well as change its waste disposal techniques during the next NPDES permit renewal in 2023. PNM is unable to predict the outcome of these matters or a range of the potential costs of compliance.
Santa Fe Generating Station
PNM and NMED are parties to agreements under which PNM has installed a remediation system to treat water from a City of Santa Fe municipal supply well and an extraction well to address gasoline contamination in the groundwater at the site of PNM’s former Santa Fe Generating Station and service center. A 2008 NMED site inspection report states that neither the source nor extent of contamination at the site has been determined and that the source may not be the former Santa Fe Generating Station. During 2013 and 2014, PNM and NMED collected additional samples that showed elevated concentrations of nitrate and volatile organic compounds in some of the monitoring wells at the site. In addition, one monitoring well contained free-phase hydrocarbon products. PNM collected a sample of the product for “fingerprint” analysis. The results of this analysis indicated the product was a mixture of older and newer fuels. The presence of newer fuels in the sample suggests the hydrocarbon product likely originated from off-site sources. In 2015, PNM and NMED entered into a memorandum of understanding to address changing groundwater conditions at the site under which PNM agreed to continue hydrocarbon investigation under the supervision of NMED. Qualified costs are eligible for payment through the New Mexico Corrective Action Fund (“CAF”), which is administered by the NMED Petroleum Storage Tank Bureau. In 2019, PNM received notice from NMED that an abatement plan for the site is required to address concentrations of previously identified compounds, unrelated to those discussed above, found in the groundwater. NMED approved PNM’s abatement plan proposal, which covers field work and reporting.
Field work related to the investigation under both the CAF and abatement plan requirements was completed and activities and findings associated with the field work were presented in two separate reports and released to stakeholders in early 2020. Subsequent field work was completed in July 2020 and two reports were released supporting PNM’s contention

(Unaudited)
that off-site sources have impacted, and are continuing to impact, the local groundwater in the vicinity of the former Santa Fe Generating Station.
In 2021, NMED approved both the field work plans required for site characterization and associated work activities which were completed by the end of 2022 and a report was submitted to the NMED in 2023. Groundwater sampling for the abatement plan’s first semiannual work was completed in 2023, and the associated report was completed and submitted to the NMED. In addition, the work plan for the 2023 CAF work was completed and submitted to the NMED in July 2023. NMED approved this work plan in December 2023. The activities from the work plan include the installation of three monitoring wells and additional rounds of groundwater sampling and are anticipated to begin in late 2024.
The City of Santa Fe has stopped operating its well at the site, which is needed for PNM’s groundwater remediation system to operate. As a result, PNM has stopped performing remediation activities at the site. However, PNM’s monitoring and other abatement activities at the site are ongoing and will continue until the groundwater meets applicable federal and state standards or until the NMED determines remediation is not required, whichever is earlier. PNM is not able to assess the duration of this project or estimate the impact on its obligations if PNM is required to resume groundwater remediation activities at the site. PNM is unable to predict the outcome of these matters.
Coal Combustion Residuals Waste Disposal
CCRs consisting of fly ash, bottom ash, and gypsum generated from coal combustion and emission control equipment at SJGS are currently disposed of in the surface mine pits adjacent to the plant. SJGS does not operate any CCR impoundments or landfills. The NMMMD currently regulates mine reclamation activities at the San Juan mine, including placement of CCRs in the surface mine pits, with federal oversight by the OSM. APS disposes of CCRs in ponds and dry storage areas at Four Corners. Ash management at Four Corners is regulated by EPA and the New Mexico State Engineer’s Office.
EPA’s final coal ash rule, which became effective in 2015, included a non-hazardous waste determination for coal ash and sets minimum criteria for existing and new CCR landfills and surface impoundments. In 2016, the Water Infrastructure Improvements for the Nation Act (the “WIIN Act”) was signed into law to address critical water infrastructure needs in the U.S. and contains a number of provisions related to the CCR rules. Among other things, the WIIN Act allows, but does not require, states to develop and submit CCR permit programs for EPA approval, provides flexibility for states to incorporate EPA’s final rule for CCRs or develop other criteria that are at least as protective as EPA’s final rule, and requires EPA to approve state permit programs within 180 days of submission by the state. Because states are not required to implement their own CCR permit programs, EPA will implement the permit program in states that choose not to implement a program, subject to Congressional funding. Until permit programs are in effect, EPA has authority to directly enforce the CCR rule. For facilities located within the boundaries of Native American reservations, such as the Navajo Nation where Four Corners is located, EPA is required to develop a federal permit program regardless of appropriated funds.
In 2018, EPA published a rule that constitutes “Phase One, Part One” of its ongoing reconsideration and revision of the April 17, 2015, CCR rule. The final Phase One, Part One rule includes two types of revisions. The first revision extended the deadline to allow EGUs with unlined impoundments or that fail to meet the uppermost aquifer requirement to continue to receive coal ash until October 31, 2020. This deadline was again extended by subsequent amendments. The rule also authorized a “Participating State Director” or EPA to approve suspension of groundwater monitoring requirements and to issue certifications related to the location restrictions, design criteria, groundwater monitoring, remedy selection and implementation. The rule also modified groundwater protection standards for certain constituents, which include cobalt, molybdenum, lithium, and lead without a maximum contamination level.
In 2019, EPA published a second round of revisions, which are commonly referred to as the “Phase Two” revisions. Phase Two proposed revisions to reporting and accessibility to public information, the “CCR piles” and “beneficial use” definitions and the requirements for management of CCR piles. EPA has reopened and extended the Phase Two comment period several times. EPA has not yet finalized provisions in Phase Two related to beneficial use of CCR and CCR piles. This activity is on EPA’s long-term agenda, which means EPA has no plans to address these issues in the next 12 months.
Since promulgating its Phase Two proposal, EPA has finalized two other rules addressing various CCR rule provisions. In 2019, EPA promulgated its proposed Holistic Approach to Closure Part A (“Part A”), which proposed a new deadline of August 31, 2020, for companies to initiate closure of unlined CCR impoundments. In accordance with the DC Circuit Court of Appeals’ vacatur of portions of the CCR Rule, Part A also proposed changing the classification of compacted soil-lined or clay-lined surface impoundments from “lined” to “unlined”. In addition, Part A delineated a process for owners/operators to submit requests for alternative closure deadlines based on lack of alternate disposal capacity. EPA issued the final Part A, which

became effective on September 28, 2020. This rule finalized the classification of soil-lined and clay-lined surface impoundments as unlined, thus, triggering closure or retrofit requirements for those impoundments. The final Part A also gave operators of unlined impoundments until April 11, 2021 to cease receipt of waste at these units and initiate closure.
In 2020, EPA issued the proposed Holistic Approach to Closure Part B (“Part B”), which delineated the process for owners/operators to submit alternate liner demonstrations for clay-lined surface impoundments that could otherwise meet applicable requirements. Part B also proposed regulations addressing beneficial use for closure of surface impoundments. EPA issued the final Part B rule, which became effective on December 14, 2020. This rule did not include beneficial use of CCR for closure, which EPA explains will be addressed in subsequent rulemaking actions. On May 18, 2023, EPA published a proposed rule on the regulatory requirements for inactive surface impoundments at inactive facilities including groundwater monitoring, corrective action, closure, and post-closure care requirements for all CCR management units (regardless of how or when that CCR was placed), and several technical corrections to the existing regulations. Comments on the proposed rule were due July 17, 2023. EPA intends to issue other rulemakings and finalizing parts of previously proposed rules, including a final rule on remaining Part B issues regarding closure options and annual reporting. EPA has not set a date for final action on these remaining rulemakings.
On May 8, 2024, EPA published a final rule that extends federal CCR regulatory requirements to (1) inactive CCR surface impoundments at inactive utilities and (2) CCR management units (“CCRMU”), including CCR impoundments and landfills that closed prior to the effective date of the 2015 CCR rule, inactive CCR landfills, and other areas where CCR is managed directly on the land. EPA included deferral options for smaller CCRMU containing between one and 1,000 tons of CCR, CCRMU located beneath critical infrastructure or large buildings or structures vital to the continuation of current site activities, and CCRMU that closed prior to the effective date of the new rule. EPA also codified the controversial definitions of infiltration and liquids that are being litigated in the DC Circuit. SJGS does not have regulated CCR units under the 2015 federal CCR regulatory program but will be required to conduct the two-part CCRMU facility evaluation process as set forth in the rule.
In 2020, EPA published a proposed rule establishing a federal permitting program for the handling of CCR within the boundaries of Native American reservations and in states without their own federally authorized state programs. Permits for units within the boundaries of Native American reservations would be due 18 months after the effective date of the rule. The Spring 2024 Unified Agenda states the final rule for the federal permit will be published in October 2024. EPA is coordinating with the affected permits for the three facilities with CCR disposal units located on Native American lands. PNM cannot predict the outcome of EPA’s rulemaking activity or the outcome of any related litigation, and whether or how such a ruling would affect operations at Four Corners.
The CCR rule does not cover mine placement of coal ash. OSM is expected to publish a proposed rule covering mine placement in the future and will likely be influenced by EPA’s rule and the determination by EPA that CCRs are non-hazardous. PNM cannot predict the outcome of OSM’s proposed rulemaking regarding CCR regulation, including mine placement of CCRs, or whether OSM’s actions will have a material impact on PNM’s operations, financial position, or cash flows. Based upon the requirements of the final Part A CCR rule, PNM conducted a CCR assessment at SJGS and made minor modifications at the plant to ensure that there are no facilities that would be considered impoundments or landfills under the rule. PNM would seek recovery from its retail customers of all CCR costs for jurisdictional assets that are ultimately incurred.
Utilities that own or operate CCR disposal units, such as those at Four Corners, as indicated above, were required to collect sufficient groundwater sampling data to initiate a detection monitoring program. Four Corners completed the analysis for its CCR disposal units, which identified several units that needed corrective action or needed to cease operations and initiate closure by April 11, 2021. Work is ongoing. Four Corners continues to gather additional groundwater data and perform remedial evaluations and activities. At this time, PNM does not anticipate its share of the cost to complete these corrective actions to close the CCR disposal units, or to gather and perform remedial evaluations on groundwater at Four Corners, will have a significant impact on its operations, financial position, or cash flows.

Other Commitments and Contingencies
Coal Supply
Four Corners
APS purchases all of Four Corners’ coal requirements from NTEC, an entity owned by the Navajo Nation, under the Four Corners CSA that expires in 2031. The coal comes from reserves located within the Navajo Nation. The contract provides for pricing adjustments over its term based on economic indices and certain minimum payments that may be required if no deliveries of coal are taken. PNM’s share of the coal costs is being recovered through the FPPAC. See additional discussion of the Four Corners CSA in Note 17 of the Notes to Consolidated Financial Statements in the 2023 Annual Reports on Form 10-K.
Coal Mine Reclamation
As indicated under Coal Combustion Residuals Waste Disposal above, SJGS disposed of CCRs in the surface mine pits adjacent to the plant and Four Corners disposes of CCRs in ponds and dry storage areas.
Under the terms of the SJGS CSA, PNM and the other SJGS owners are obligated to compensate WSJ LLC for all reclamation costs associated with the supply of coal from the San Juan mine. PNM and Westmoreland have entered into an agreement under which mine reclamation services for SJGS would be provided. A mine reclamation cost study was completed in the first quarter of 2024 and PNM remeasured its liability, which resulted in an increase in overall reclamation costs of $20.9 million, due primarily to higher inflationary factors. As a result, PNM recorded the increase in the liability related to the underground mine of $17.0 million as a regulatory asset on the Condensed Consolidated Balance Sheets. Due to the NMPRC cap on the amount that can be collected from retail customers for final reclamation of the surface mines at $100.0 million, PNM was required to record $4.0 million of the increase related to the surface mine liability plus an additional $0.5 million, related to other costs, as a regulatory disallowance on the Condensed Consolidated Statements of Earnings for the three months ended March 31, 2024. In the third quarter of 2024, PNM and Westmoreland amended the mine reclamation services agreement to update the base rates for the costs of reclamation activities, which resulted in an increase in overall reclamation costs of $12.1 million. As a result, PNM recorded the increase in the liability related to the underground mine of $6.0 million as regulatory assets on the Condensed Consolidated Balance Sheets and the increase of $6.1 million related to the surface mine as a regulatory disallowance on the Condensed Consolidated Statements of Earnings for the three and nine months ended September 30, 2024.
PNM’s estimate of the costs necessary to reclaim the mine that serves SJGS is subject to many assumptions, including the timing of reclamation, generally accepted practices at the time reclamation activities occur, and current inflation and discount rates. PNM cannot predict the ultimate cost to reclaim the mine that serves SJGS and would seek to recover all costs related to reclaiming the underground mine from its customers but could be exposed to additional loss related to surface mine reclamation. In connection with certain mining permits relating to the operation of the San Juan mine, Westmoreland was required to post reclamation bonds of $118.7 million with the NMMMD. In order to facilitate the posting of reclamation bonds by sureties on behalf of Westmoreland, TXNM entered into the WFB LOC Facility under which letters of credit aggregating $30.3 million have been issued.
A coal mine reclamation study for the mine that serves Four Corners was issued in 2019. The study reflected operation of the mine through 2031, the term of the Four Corners CSA.
Based on the most recent estimates, PNM’s remaining payments as of September 30, 2024 for mine reclamation, in future dollars, are estimated to be $48.7 million for the surface mines at both SJGS and Four Corners and $65.0 million for the underground mine at SJGS. At September 30, 2024 and December 31, 2023, liabilities, in current dollars, of $42.2 million and $50.0 million for surface mine reclamation and $54.5 million and $26.2 million for underground mine reclamation were recorded in other deferred credits.
The SJGS owners are parties to a reclamation trust funds agreement to provide financial assurance for post-term coal mine reclamation obligations. The trust funds agreement requires each owner to enter into an individual trust agreement with a financial institution as trustee, create an irrevocable reclamation trust, and meet year-end funding targets set by funding curves that are approved by the SJGS ownership. PNM began using its mine reclamation trust to pay for final mine reclamation costs in April 2023. Because the trust agreement requires meeting specific funding targets at year end, it may be necessary for PNM to make additional contributions to meet those targets. PNM funded $2.7 million in 2023. The recently completed and approved mine reclamation cost study resulted in an update to the trust’s funding curves. Based on PNM’s reclamation trust

fund balance at September 30, 2024, and current funding curve targets, PNM anticipates contributing $25.1 million in 2024, $2.4 million in 2025, and $0.6 million in 2026.
Under the Four Corners CSA, PNM is required to fund its share of estimated final reclamation costs in annual installments into an irrevocable escrow account solely dedicated to the final reclamation cost of the surface mine at Four Corners. PNM contributed $3.2 million in 2024 and $0.2 million in 2023. PNM anticipates providing additional funding of $2.1 million in 2025 and $2.9 million in 2026.
PNM recovers from retail customers reclamation costs associated with the underground mine. However, the NMPRC capped the amount collected from retail customers for final reclamation of the surface mines at $100.0 million for both SJGS and Four Corners. If future estimates increase the liability for surface mine reclamation, the excess would be expensed at that time. The impacts of changes in New Mexico state law as a result of the enactment of the ETA and regulatory determinations made by the NMPRC may also affect PNM’s financial position, results of operations, and cash flows. PNM is currently unable to determine the outcome of these matters or the range of possible impacts.
SJGS Decommissioning
On November 9, 2021, the San Juan County Commission approved the Coal-Fired Electricity Generating Facility Demolition and Remediation Ordinance (“Ordinance 121”), requiring the full demolition of SJGS upon its complete and permanent closure. Ordinance 121 required the SJGS owners to submit a proposed demolition and remediation plan no later than three months after SJGS was retired. The SJGS owners submitted the decommissioning and remediation plan on December 28, 2022. In connection with restructuring of the SJGS ownership on December 31, 2017, PNM and the other SJGS owners entered into the San Juan Decommissioning and Trust Funds Agreement, which requires PNM to fund its ownership share of final decommissioning costs into an irrevocable trust. Under the agreement, PNM made an initial funding of $14.7 million in December 2022. The amount and timing of additional trust funding is subject to revised decommissioning cost studies and agreement among the SJGS owners. PNM began using its decommissioning trust to pay for demolition and decommissioning costs in October 2023. PNM has posted a surety bond in the amount of $46.0 million in connection with certain environmental decommissioning obligations and must maintain the bond or other financial assurance until those obligations are satisfied. The surety bond only represents a liability if the SJGS owners fail to deliver on its contractual liability. For information regarding the impact of Ordinance 121 on PNM’s SJGS decommissioning ARO see Note 15 of the Notes to Consolidated Financial Statements in the 2023 Annual Reports on Form 10-K.
PNM records its share of the SJGS decommissioning obligation as an ARO on its Condensed Consolidated Balance Sheets. Studies on the decommissioning costs of SJGS are performed periodically and revisions to the ARO liability are recorded. In the third quarter of 2022, a new decommissioning cost study was completed, which required PNM to remeasure its SJGS decommissioning ARO. The new study resulted in an estimated decrease to PNM’s share of the decommissioning obligation of $21.1 million, which was recorded in September 2022. Additional information concerning the Company’s SJGS decommissioning ARO is contained in Note 15 of the Notes to Consolidated Financial Statements in the 2023 Annual Reports on Form 10-K.
PVNGS Liability and Insurance Matters
Public liability for incidents at nuclear power plants is governed by the Price-Anderson Nuclear Industries Indemnity Act, which limits the liability of nuclear reactor owners to the amount of insurance available from both commercial sources and an industry-wide retrospective payment plan. The insurance limit is subject to an adjustment every five years based upon the aggregate percentage change in the CPI. The most recent adjustment took effect on January 1, 2024. As of that date, in accordance with this act, the PVNGS participants are insured against public liability exposure for a nuclear incident up to $16.3 billion per occurrence. PVNGS maintains the maximum available nuclear liability insurance in the amount of $500 million, which is provided by American Nuclear Insurers. The remaining $15.8 billion is provided through a mandatory industry-wide retrospective assessment program. If losses at any nuclear power plant covered by the program exceed the accumulated funds, PNM could be assessed retrospective premium adjustments. The maximum retrospective premium per reactor under the program for each nuclear liability incident is $165.9 million, subject to a maximum annual premium of $24.7 million per incident. Based on PNM’s ownership interest in the three Palo Verde units, PNM’s maximum retrospective premium per incident for all three units is $36.3 million, with a maximum annual payment limitation of $5.4 million, to be adjusted periodically for inflation.

The PVNGS participants maintain insurance for damage to, and decontamination of, property at PVNGS in the aggregate amount of $2.8 billion, a substantial portion of which must first be applied to stabilization and decontamination. These coverages are provided by Nuclear Electric Insurance Limited (“NEIL”). The primary policy offered by NEIL contains a sublimit of $2.25 billion for non-nuclear property damage. If NEIL’s losses in any policy year exceed accumulated funds, PNM is subject to retrospective premium adjustments of $5.1 million. The insurance coverages discussed in this and the previous paragraph are subject to certain policy conditions, sublimits, and exclusions.
(12) Regulatory and Rate Matters
The Company is involved in various regulatory matters, some of which contain contingencies that are subject to the same uncertainties as those described in Note 11. Additional information concerning regulatory and rate matters is contained in Note 17 of the Notes to Consolidated Financial Statements in the 2023 Annual Reports on Form 10-K.
PNM
New Mexico General Rate Case
2025 Rate Request
On June 14, 2024, PNM filed an application with the NMPRC for a general increase in retail electric rates. The proposed base rate changes would be implemented in two phases, with the first phase effective July 1, 2025 and the second phase effective January 1, 2026. Key aspects of PNM’s request include:
•Recovery on total rate base of $3.0 billion, based on a FTY with the 12 months ending June 30, 2026
•An increase of $174.3 million in retail revenues, comprised of a $92.2 million increase in base rates and a $82.1 million increase in revenues collected under PNM’s FPPAC
•Drivers of revenue deficiency:
◦Needed investments across distribution, transmission, and generation facilities to ensure safe, reliable delivery of electricity
◦Increased operations and maintenance expenses to meet operational needs, including wildfire risk mitigation
◦Costs associated with ESAs, previously approved by the NMPRC, necessary to serve our customers
◦ROE of 10.45%
◦Proposed capital structure of 52.5% equity
◦An increased cost of borrowing
◦Adjustments to Four Corners depreciation rates to recover remaining plant investments through July 2031, the expected abandonment date of the facility
•Proposed ratemaking treatment of ESAs to be recovered through PNM’s FPPAC beginning July 1, 2025
The NMPRC has suspended PNM’s advice notice in the case for the statutory suspension period, until July 15, 2025 and the hearing examiners set a procedural schedule with a hearing to begin February 17, 2025.
2024 Rate Change
On December 5, 2022, PNM filed an application with the NMPRC for a general increase in retail electric rates including recovery on total rate base of $2.7 billion based on a calendar year 2024 FTY, an increase of $63.8 million in retail non-fuel revenues, and an ROE 10.25%. The application also proposed ratemaking treatment of PVNGS Leased Interest and testimony supporting the prudence of PNM’s decisions to renew the five leases and repurchase 64.1 MW of PVNGS Unit 2 capacity.
On January 3, 2024, the NMPRC issued a final order authorizing PNM to implement an increase in non-fuel base rates of $15.3 million, effective for service beginning January 15, 2024. Major components of the difference compared to PNM’s application include:
•A ROE of 9.26%.
•A capital structure of 49.61% equity, 50.10% debt, and 0.29% preferred stock.
•Finding of imprudence regarding PNM’s decision to remain in Four Corners and a remedy for the imprudence resulting in a disallowance of $81.0 million to PNM’s total Four Corners net book value.

•Approval of $51.3 million of PNM’s requested $96.3 million regulatory asset for PVNGS undepreciated investments, but disallowance of a return on the remaining $45.0 million or any CWIP associated with it.
•Requiring that the $38.4 million regulatory liability associated with leased capacity at PVNGS after the Unit 1 lease expired on January 15, 2023, be returned to ratepayers over two years through a separate rate rider.
•The approval of new depreciation rates, reflecting shorter useful lives, of PNM’s gas plants with service lives and depreciable lives extending beyond January 1, 2045, which would include PNM’s La Luz and Luna generating stations.
•The approval of PNM’s TOD pilot program, with a requirement to make annual compliance filings and to adjust certain rate schedules.
For additional details related to the initial application, see Note 17 of the Notes to Consolidated Financial Statements in the 2023 Annual Reports on Form 10-K.
In the year ended December 31, 2023, PNM evaluated the outcome of the NMPRC final order in the 2024 Rate Change and recorded a regulatory disallowance of $55.5 million on the Consolidated Statement of Earnings and a corresponding reduction to Utility Plant, after accounting for previous impairments, to reflect the remedy adopted in the Final Order for Four Corners. In addition, PNM recorded a reduction to electric operating revenues of $38.4 million with a corresponding current regulatory liability of $19.2 million and a deferred regulatory liability of $19.2 million for the PVNGS rate refunds that will be returned to customers over a two-year period. PNM also recorded a regulatory disallowance of $8.2 million on the Consolidated Statement of Earnings and a corresponding reduction to Utility Plant for the disallowance of CWIP from PVNGS.
In March 2024, notice of appeals were separately filed with the NM Supreme Court by NEE and PNM, and a joint notice of appeal was filed by the NM Department of Justice, Bernalillo County, and ABCWUA. NEE’s appeal was subsequently consolidated with the joint notice of appeal. In the statements of issues submitted in the parties’ appellate dockets, PNM took issue with the NMPRC’s ruling on capital structure; other appellants primarily challenged the NMPRC rulings related to Four Corners and Palo Verde cost recovery. PNM cannot predict the outcome of this matter.
Renewable Energy Portfolio Standard
As discussed in Note 11, the ETA amends the REA including removal of diversity requirements and certain customer caps and exemptions relating to the application of the RPS under the REA. The REA provides for streamlined proceedings for approval of utilities’ renewable energy procurement plans, assures that utilities recover costs incurred consistent with approved procurement plans, and requires the NMPRC to establish a Reasonable Cost Threshold (“RCT”) for the procurement of renewable resources to prevent excessive costs being added to rates. The ETA sets a RCT of $60 per MWh, adjusted for inflation, using an average annual levelized resource cost basis. PNM makes renewable procurements consistent with the NMPRC approved plans and recovers certain renewable procurement costs from customers through the renewable energy rider billed on a KWh basis.
Included in PNM’s approved procurement plans are the following renewable energy resources:
•158 MW of PNM-owned solar-PV facilities
•A PPA through 2044 for the output of New Mexico Wind, having a current aggregate capacity of 200 MW, and a PPA through 2035 for the output of Red Mesa Wind, having an aggregate capacity of 102 MW
•A PPA through 2040 for 140 MW of output from La Joya Wind II
•A PPA through 2042 for the output of the Lightning Dock Geothermal facility with a capacity of 11 MW
•Solar distributed generation, aggregating 302.4 MW at September 30, 2024, owned by customers or third parties from whom PNM purchases any net excess output and RECs
The NMPRC has authorized PNM to recover certain renewable procurement costs through a rate rider billed on a per KWh basis. In its 2024 renewable energy procurement plan, which became effective on January 1, 2024, PNM proposed to collect $59.0 million for the year. PNM recorded revenues from the rider of $11.1 million and $41.7 million in the three and nine months ended September 30, 2024 and $13.0 million and $47.0 million in the three and nine months ended September 30, 2023. On June 3, 2024, PNM filed its renewable energy procurement plan for 2025 which proposes to collect $58.7 million for the year. PNM did not propose any new resource procurements, and the plan states that existing projects are anticipated to exceed the applicable RPS standards of 2025, despite the standard doubling. On September 11, 2024, a public hearing was held and on October 11, 2024, the hearing examiners issued a RD recommending approval of all PNM’s requests.

Under the renewable rider, if PNM’s earned rate of return on jurisdictional equity in a calendar year, adjusted for items not representative of normal operations, exceeds the NMPRC-approved rate by 0.5%, PNM is required to refund the excess to customers during May through December of the following year. PNM did not exceed such limitation in 2023.
Energy Efficiency and Load Management
Program Costs and Incentives/Disincentives
The New Mexico Efficient Use of Energy Act (“EUEA”) requires public utilities to achieve specified levels of energy savings and to obtain NMPRC approval to implement energy efficiency and load management programs. The EUEA requires the NMPRC to remove utility disincentives to implementing energy efficiency and load management programs and to provide incentives for such programs. The NMPRC has adopted a rule to implement this act. PNM’s costs to implement approved programs and incentives are recovered through a rate rider. During the 2019 New Mexico legislative session, the EUEA was amended to, among other things, include a decoupling mechanism for disincentives, preclude a reduction to a utility’s ROE based on approval of disincentive or incentive mechanisms, establish energy savings targets for the period 2021 through 2025, and require that annual program funding be 3% to 5% of an electric utility’s annual customer bills excluding gross receipt taxes, franchise and right-of-way access fees, provided that a customer’s annual cost does not exceed seventy-five thousand dollars.
On April 17, 2023, PNM filed an application for energy efficiency and load management programs to be offered in 2024, 2025, and 2026 (the “2024 Plan”). The 2024 Plan proposed to continue ten existing energy efficiency programs with modification and a total annual budget of $34.5 million in 2024, $35.4 million in 2025, and $36.5 million in 2026. The application also sought approval of an annual base incentive of 7.1% of the portfolio budget and a sliding scale that provides additional incentive for additional energy saved as a percentage of program cost, up to the maximum allowed by the energy efficiency rule which for PNM is 8.82%. On January 26, 2024, the hearing examiners in the case issued a RD. The RD largely approved PNM’s 2024 Plan but with modifications that include the pursuit of demand response resources, additional analysis in future filings, adjustments to certain energy efficiency programs, and modification of the incentive sliding scale cap to reflect a new maximum. On March 7, 2024, the NMPRC approved the RD in its entirety.
2020 Decoupling Petition
As discussed above, the legislature amended the EUEA to, among other things, include a decoupling mechanism for disincentives. On May 28, 2020, PNM filed a petition for approval of a rate adjustment mechanism that would decouple the rates of its residential and small power rate classes. Decoupling is a rate design principle that severs the link between the recovery of fixed costs of the utility through volumetric charges. On July 13, 2020, NEE, ABCWUA, the City of Albuquerque, and Bernalillo County filed motions to dismiss the petition on the grounds that approving PNM’s proposed rate adjustment mechanism outside of a general rate case would result in retroactive ratemaking and piecemeal ratemaking. The motions to dismiss also alleged that PNM’s proposed rate adjustment mechanism is inconsistent with the EUEA. On October 2, 2020, PNM requested an order to vacate the public hearing, scheduled to begin October 13, 2020, and staying the proceeding until the NMPRC decides whether to entertain a petition to issue a declaratory order resolving the issues raised in the motions to dismiss. On October 7, 2020, the hearing examiner approved PNM’s request to stay the proceeding and vacate the public hearing and required PNM to file a petition for declaratory order by October 30, 2020. On October 30, 2020, PNM filed a petition for declaratory order asking the NMPRC to issue an order finding that full revenue decoupling is authorized by the EUEA. On November 4, 2020, ABCWUA and Bernalillo County jointly filed a competing petition asking the NMPRC to issue a declaratory order on the EUEA’s requirements related to disincentives. On March 17, 2021, the NMPRC issued an order granting the petitions for declaratory order, commencing a declaratory order proceeding to address the petitions and appointing a hearing examiner to preside over the declaratory order proceeding.
On January 14, 2022, the hearing examiner issued a RD recommending the NMPRC find that the EUEA does not mandate the NMPRC to authorize or approve a full decoupling mechanism, defining full decoupling as limited to energy efficiency and load management measures and programs. The RD also states that a utility may request approval of a rate adjustment mechanism to remove regulatory disincentives to energy efficiency and load management measures and programs through a stand-alone petition, as part of the utility’s triennial energy efficiency application or a general rate case and that PNM is not otherwise precluded from petitioning for a rate adjustment mechanism prior to its next general rate case. Finally, the RD stated that the EUEA does not permit the NMPRC to reduce a utility’s ROE based on approval of a disincentive removal mechanism founded on removing regulatory disincentives to energy efficiency and load management measures and programs. The RD does not specifically prohibit a downward adjustment to a utility’s capital structure, based on approval of a disincentive removal mechanism. On April 27, 2022, the NMPRC issued an order adopting the RD in its entirety. On May 24, 2022, PNM filed a notice of appeal with the NM Supreme Court. The NM Supreme Court held oral arguments on November 13, 2023. On

May 13, 2024, the NM Supreme Court issued a decision finding that the EUEA allows a utility to propose full decoupling mechanisms. The NM Supreme Court did not address the second issue regarding a downward adjustment to a utility’s capital structure based on approval of disincentive removal mechanism. No declaratory order was issued by the NMPRC. This matter is now concluded.
Integrated Resource Plans
NMPRC rules require that investor-owned utilities file an IRP every three years. The IRP is required to cover a 20-year planning period and contain an action plan covering the first three years of that period. On September 14, 2022, the NMPRC adopted revisions to the IRP Rule. The new rule revamps and modernizes the planning process to accommodate increased stakeholder involvement. The IRP Rule establishes a collaborative facilitated process for a utility and stakeholders to agree on a statement of need for potential new or additional resources, as well as an action plan to guide procurement or development of resources to meet the stated need. A most-cost-effective portfolio of resources shall be derived from the statement of need analysis. The statement of need and action plan must be accepted before the utility begins the resource solicitation process pursuant to the IRP Rule. Following acceptance of the statement of need and action plan, a utility will provide the NMPRC and intervenors drafts of the request for proposals (“RFP”) and a timeline for issuing, receiving, evaluating, and ranking bids. The NMPRC will then appoint an Independent Monitor (“IM”) to oversee the RFP process, which allows for parties and the IM to comment on the RFP consistency with the IRP, after which the utility issues the RFP. Within 120 days of receiving bids the utility shall provide the IM with results including pricing and non-price evaluation criteria, ranking of bids, chosen portfolio and alternatives that also meet the needs; the IM then rules on the fairness of the RFP execution. Acceptance of the statement of need and action plan will not constitute a finding of prudency or pre-approval of costs associated with the additional resources. Following the RFP and IM processes, the utility may apply for approvals, and any costs incurred to implement the action plan will be considered in a general rate case and/or resource acquisition proceeding. On October 14, 2022, PNM and other investor-owned utilities filed motions for rehearing with the NMPRC. On October 26, 2022, the NMPRC issued an order partially granting and partially denying certain aspects of PNM’s and the other investor-owned utilities’ motions for rehearing. On November 2, 2022, the NMPRC adopted an amended IRP Rule. On December 2, 2022, PNM filed an appeal with the NM Supreme Court. Two other investor-owned utilities also separately filed appeals at the NM Supreme Court. On January 3, 2023, PNM and the two other investor-owned utilities filed statements of issues with the NM Supreme Court. Among other things, the investor-owned utilities question whether the IRP Rule exceeds the NMPRC authority by imposing unauthorized requirements on utilities and extending NMPRC jurisdiction through over-broad interpretation of the statutes and state that the IRP Rule is contrary to law in its provisions for NMPRC regulation of a utility’s resource procurement decision-making. On June 5, 2023, PNM and the other two investor-owned utilities filed their Joint Brief in Chief and request for oral arguments at the NM Supreme Court. The NM Supreme Court held oral arguments on May 13, 2024. PNM cannot predict the outcome of this matter.
2023 IRP
On December 15, 2023, PNM filed its 2023 IRP with a continued focus on a carbon-free energy system by 2040. The plan highlights the need for the significant sustained addition of resources over the next two decades, replacing retiring or expiring capacity, meeting concurrent load growth, while reducing the carbon intensity of PNM’s portfolio. On April 4, 2024, the NMPRC accepted PNM’s 2023 IRP. On May 2, 2024, the NMPRC issued an order appointing an independent monitor who will report the results of PNM’s 2023 IRP.
Abandonment Applications made under the ETA
SJGS Abandonment Application
In 2019, PNM filed a Consolidated Application for the Abandonment and Replacement of SJGS and Related Securitized Financing Pursuant to the ETA. In 2023, PNM, along with intervening parties, reached a unanimous settlement which was approved by the NMPRC. As a result, PNM recorded a $115.0 million reduction to electric operating revenues on TXNM’s and PNM’s Condensed Consolidated Statement of Earnings, for amounts previously recorded under PNM’s current retail rates and a corresponding current regulatory liability on TXNM’s and PNM’s Condensed Consolidated Balance Sheets at September 30, 2023. In addition, PNM recorded a regulatory disallowance of $2.3 million on TXNM’s and PNM’s Condensed Consolidated Statement of Earnings and a corresponding decrease to deferred regulatory assets on TXNM’s and PNM’s Condensed Consolidated Balance Sheets at September 30, 2023 to reflect PNM’s agreement to withdraw its request for regulatory assets associated with prefunding of ETA state administered funds and legal costs associated with this matter. Additional information is contained in Note 17 of the Notes to Consolidated Financial Statements in the 2023 Annual Reports on Form 10-K.

Four Corners Abandonment Application
In 2020, PNM entered into the Four Corners Purchase and Sale Agreement with NTEC, pursuant to which PNM agreed to sell its 13% ownership interest (other than certain transmission assets) in Four Corners to NTEC, contingent upon NMPRC approval. In connection with the sale, PNM would make payments of $75.0 million to NTEC for relief from its obligations under the coal supply agreement for Four Corners after December 31, 2024. PNM made an initial payment to NTEC of $15.0 million in November 2020, subject to refund with interest upon termination of the Four Corners Purchase and Sale Agreement prior to closing. Under the terms of the Four Corners Purchase and Sale Agreement, upon receipt of the NMPRC approval, PNM was expected to make a final payment of $60.0 million.
On January 8, 2021, PNM filed the Four Corners Abandonment Application, which sought NMPRC approval to exit PNM’s share of Four Corners as of December 31, 2024, and issuance of approximately $300 million of Securitized Bonds as provided by the ETA. On December 15, 2021, the NMPRC issued a final order denying approval of the Four Corners Abandonment Application and the corresponding request for issuance of securitized financing. On December 22, 2021, PNM filed a Notice of Appeal with the NM Supreme Court of the NMPRC decision to deny the application and on July 6, 2023, the NM Supreme Court affirmed the NMPRC decision concluding that the NMPRC reasonably and lawfully denied PNM’s application for abandonment. As a result of the NM Supreme Court's decision to uphold the NMPRC's denial, the Condensed Consolidated Statements of Earnings for the three and nine months ended September 30, 2023 reflect a regulatory disallowance of $3.7 million. On April 23, 2024, PNM filed an interim notice informing the NMPRC that PNM’s updated analysis indicates it is in the interest of customers for PNM to remain as a participant in Four Corners until the expiration of the current coal supply agreement in 2031. In August 2024, PNM and NTEC terminated the Four Corners Purchase and Sale Agreement and executed an agreement for the reimbursement of PNM’s initial $15.0 million payment with interest, to be paid in 2024.
Summer Peak Resource Adequacy
Beginning in 2021 PNM began providing notices of delays, as received from developers, and status updates to the NMPRC for the approved SJGS replacement resource projects as well as delays in replacement resources for the PVNGS leased capacity that expired in January 2023 and January 2024. PNM’s generation resources performed sufficiently with no challenges to resource adequacy during the 2023 and 2024 summer peak seasons. While some of the replacement resources have come online, other replacement resources have experienced additional developer delays and PNM entered into additional firm energy market purchases necessary to meet customer load during the 2024 summer season. See Note 7.
2026 Resource Application
On October 25, 2023, PNM filed an application with the NMPRC seeking approval of resources to be available for the 2026 summer peak. The application included a request for approval of a 100 MW solar PPA and three battery storage agreements of 100 MW, 100 MW, and 50 MW. In addition, PNM was seeking approval of a CCN for a 60 MW battery storage system to be owned by PNM. The resources were deemed necessary for PNM to safely and reliably meet its projected system load. A hearing was held on March 20 and 21, 2024. On May 3, 2024, the hearing examiner in the case issued a RD approving PNM’s requested resources. On May 30, 2024, the NMPRC approved the RD in its entirety. On July 9, 2024, a group of New Mexico legislators filed a petition with the NM Supreme Court requesting the court grant their motion for rehearing, which was denied on September 3, 2024. This matter is now concluded.
Grid Modernization Application
On October 3, 2022, in compliance with New Mexico Grid Modernization Statute, PNM filed its Grid Modernization Application with the NMPRC. The projects included in the Grid Modernization Application improve customers’ ability to customize their use of energy and ensure that customers, including low-income customers, are a top priority and will benefit consistent with the Grid Modernization Statute. PNM’s proposal to modernize its electricity grid through infrastructure and technology improvements also increases the efficiency, reliability, resilience, and security of PNM’s electric system. PNM’s application seeks approval of grid modernization investments of approximately $344 million for the first six years of a broader 11-year strategy. The proposed Grid Modernization Rider would recover capital costs, operating expenses, and taxes associated with the investments included in the Grid Modernization Application. PNM also requested authorization to create related regulatory assets and liabilities, permitting PNM to record costs incurred for the development and implementation of PNM’s plan between the requested approval of the application on July 1, 2023, and the implementation of the Grid Modernization Rider by September 1, 2023; undepreciated investments associated with legacy meters being replaced with AMI meters; and over- or under-collection of costs through the Grid Modernization Rider. In addition, PNM requested approval of the proposed

format of an Opt-Out Consent Form and proposed opt-out fees, which includes a one-time fee and a monthly fee. Following a hearing and subsequent briefs, on May 31, 2023, the NMPRC issued an order requiring the hearing examiner to direct PNM to file a cost benefit analysis as a supplement to the application. On November 22, 2023, PNM filed the required cost benefit analysis supporting PNM’s proposed Grid Modernization plan. A hearing was held in April 2024 and post-hearing briefs and response briefs were filed in June 2024. On August 16, 2024, the hearing examiner in the case issued a RD. The RD largely approved PNM’s application with minor modifications, including limiting to a return of its undepreciated costs of legacy meters and conditioned approval upon PNM accelerating the deployment schedule following a final order. On October 17, 2024, the NMPRC issued a final order adopting the RD but removed the accelerated deployment schedule.
The Community Solar Act
In 2021, the Community Solar Act established a program that allows for the development of community solar facilities and provides customers of a qualifying utility with the option of subscribing to community solar facilities, and in exchange would receive a bill credit from their utility, while the utility received energy from the community solar facility. The NMPRC was charged with administering the Community Solar Act program, establishing a total maximum capacity of 200 MW community solar facilities and allocating proportionally to the New Mexico electric investor-owned utilities and participating cooperatives, of which PNM was allocated 125 MW. On October 3, 2024, the NMPRC issued an order raising the total maximum capacity of community solar facilities by 300 MW, of which PNM was allocated 185 MW.
In 2022, PNM filed its initial Community Solar tariff and subsequently filed an updated Community Solar tariff under protest and filed a motion for clarification, suspension, and timely hearing on PNM’s Community Solar tariff. In 2023, the NMPRC suspended PNM’s Community Solar tariff and issued an order opening a new docket for two-phase proceedings. The first phase addressed issues concerning the proposed subscriber organization agreements and the proposed customer data forms. The second phase addressed all issues concerning proposed tariffs, agreements and forms that were not addressed in the first phase. In 2023, the NMPRC issued an order approving an uncontested stipulation on the first phase and PNM’s advice notice conforming to the stipulation became effective. A hearing for the second phase was held from January 17 through January 19, 2024. On August 30, 2024, the hearing examiner issued a RD. The RD recommended rejecting PNM’s proposed community solar rider and required PNM to refile the rider, approval of an accounting order to track certain costs in a regulatory asset, and included recommendations for various issues to be handled in a future rulemaking. PNM cannot predict the outcome of the pending matters.
Transportation and Electrification Program (TEP)
On June 1, 2023, PNM filed its 2024-2026 TEP with the NMPRC, requesting approval of a $37.1 million total three-year budget and continuation of the current TEP Rider. Approximately 22% of the budget, $8.0 million, will be dedicated to low-income customers. On February 2, 2024, the hearing examiners in the case issued a RD largely approving PNM’s 2024 Plan but with modifications to certain TEP programs. On February 23, 2024, the NMPRC approved the RD with additional modifications that reduced the three-year budget by $4.0 million, for a total revised budget of $32.9 million. The TEP rider became effective on April 26, 2024.
TNMP
Transmission Cost of Service Rates
TNMP can update its TCOS rates twice per year to reflect changes in its invested capital although updates are not allowed while a general rate case is in process. Updated rates reflect the addition and retirement of transmission facilities, including appropriate depreciation, federal income tax and other associated taxes, and the approved rate of return on such facilities. The following sets forth TNMP’s recent interim transmission cost rate increases:

Effective Date |  | Approved Increase in Rate Base |  | Annual Increase in Revenue
|  | (In millions)
May 12, 2023 |  | $ | 150.5 |  |  | $ | 19.4 |

Periodic Distribution Rate Adjustment
PUCT rules permit interim rate adjustments to reflect changes in investments in distribution assets. Historically, distribution utilities have been restricted to a single, annual periodic rate adjustment through a DCRF submitted between April 1 and April 8 of each year as long as the electric utility was not earning more than its authorized rate of return using weather-normalized data. However, the recent passage of Senate Bill 1015 now permits DCRF proceedings to be filed twice per year with a 60-day administrative deadline that can be extended for 15 days on good cause. Additionally, a DCRF may be filed during a pending rate case proceeding as long as that DCRF request is not filed until the 185th day after the rate case proceeding was initiated. The following sets forth TNMP’s recent interim distribution rate increases:

Effective Date |  | Approved Increase in Rate Base |  | Annual Increase in Revenue
|  | (In millions)
September 1, 2022 |  | $ | 95.7 |  |  | $ | 6.8 |

Energy Efficiency
TNMP recovers the costs of its energy efficiency programs through an energy efficiency cost recovery factor (“EECRF”), which includes projected program costs, under and over collected costs from prior years, rate case expenses, and performance bonuses (if programs exceed mandated savings goals). TNMP’s 2022 EECRF filing requested recovery of $7.3 million, including a performance bonus of $1.9 million, and became effective March 1, 2023. On May 26, 2023, TNMP filed its request to adjust the EECRF to reflect changes in costs for 2024. On September 28, 2023, the PUCT approved a unanimous stipulation, authorizing recovery of $6.6 million, including a performance bonus of $1.2 million based on TNMP’s energy efficiency achievements in the 2022 plan year. On May 31, 2024, TNMP filed its request to adjust the EECRF to reflect changes in costs for 2025. On October 24, 2024, the PUCT approved the total amount requested, authorizing recovery of $7.0 million, which includes a performance bonus of $1.3 million based on TNMP’s energy efficiency achievements in the 2023 plan year.
Hurricane Beryl
On July 8, 2024, Hurricane Beryl made landfall in the Texas Gulf Coast leaving approximately 116,000 customers in the TNMP service area without power. As of September 30, 2024, TNMP has incurred $47.2 million of costs, of which $28.6 million has been recorded in Utility Plant and $18.6 million has been recorded as a regulatory asset in Other Deferred Charges on the Condensed Consolidated Balance Sheets. TNMP will continue to track storm-related restoration costs to seek collection of such costs in a future regulatory proceeding.
System Resiliency Plan (“SRP”)
In 2023, the Texas Legislature enacted House Bill No, 2555 (“HB 2555”), permitting an electric utility to seek approval of, and cost recovery for, a system resiliency plan. On August 28, 2024, TNMP filed its first SRP with the PUCT designed to benefit customers through enhanced resiliency of its distribution system, as intended under HB 2555. The SRP includes approximately $600 million of capital investments and approximately $151 million of other related costs over three years and was developed using a comprehensive and data-driven approach which evaluated various types of resiliency events posing material risk to the safe and reliable operation of TNMP's distribution system. TNMP's service territory includes non-contiguous areas across different regions of Texas, ranging from small communities and rural areas to communities around large metropolitan areas, each with unique risks. Investments in the SRP are prioritized based on customer benefit, physical protection of infrastructure, foundational investments in operational and cybersecurity technologies, and wildfire risk reduction and are focused on lower-performing areas in the context of reliability. Eight different resiliency measures are outlined in the SRP with associated programs and infrastructure impacts to improve the system's ability to prevent, withstand, mitigate and/or more promptly recover from resiliency events: distribution system resiliency, distribution system protection modernization, vegetation management, wildfire mitigation, flood mitigation, enhanced operations system technology, cybersecurity, and

physical security resiliency. The SRP is subject to PUCT approval over 180 days as stated in Texas legislation. Recovery of investments and costs are permissible primarily through semi-annual DCRF filings, with deferral of depreciation and other certain expenses until recovery begins.
(13) Lease Commitments
The Company leases office buildings, vehicles, battery storage facilities, and other equipment. In addition, certain rights-of-way agreements are classified as leases. All of the Company’s leases with terms in excess of one year are recorded on the balance sheet by recording a present value lease liability and a corresponding right-of-use asset. Operating lease expense is recognized within operating expenses according to the use of the asset on a straight-line basis. Financing lease costs, which are comprised primarily of fleet and office equipment leases commencing after January 1, 2019, are recognized by amortizing the right-of-use asset on a straight-line basis and by recording interest expense on the lease liability. Financing lease right-of-use assets amortization is reflected in depreciation and amortization and interest on financing lease liabilities is reflected as interest charges on the Company’s Condensed Consolidated Statements of Earnings. See additional discussion of the Company’s leasing activities in Note 8 of the Notes to Consolidated Financial Statements in the 2023 Annual Reports on Form 10-K.
PVNGS
In 1985 and 1986, PNM entered into leases for its interest in PVNGS Unit 1 and 2. The leases initially were scheduled to expire in January 2015 for four Unit 1 leases and January 2016 for four Unit 2 leases. Following procedures set forth in the PVNGS leases, PNM notified four of the lessors under the Unit 1 leases and one lessor under the Unit 2 lease that it would elect to renew those leases on the expiration date of the original leases. The four Unit 1 leases expired in January 2023 and the one Unit 2 lease expired in January 2024. PNM has no further lease payments related to PVNGS Unit 1 or 2.
On April 5, 2021, PNM and Salt River Project entered into an Asset Purchase and Sale Agreement, pursuant to which PNM agreed to sell to Salt River Project certain PNM-owned assets and nuclear fuel necessary to the ongoing operation and maintenance of leased capacity in PVNGS Unit 1 and Unit 2. In January 2023, the Unit 1 leases expired, and PNM closed on the associated sale to Salt River Project, receiving payments of $33.7 million, of which $28.4 million was recorded as a reduction to Net utility plant on the Condensed Consolidated Balance Sheets and is presented as cash flows from investing activities on the Condensed Consolidated Statement of Cash Flows. In addition, $5.3 million was recorded as a reduction to materials, supplies, and fuel stock on the Condensed Consolidated Balance Sheets and is presented as cash flows from operating activities on the Condensed Consolidated Statement of Cash Flows. In January 2024, the Unit 2 leases expired, and PNM closed on the associated sale to Salt River Project, receiving payments of $3.4 million, of which $2.8 million was recorded as a reduction to Net utility plant on the Condensed Consolidated Balance Sheets and is presented as cash flows from investing activities on the Condensed Consolidated Statement of Cash Flows. In addition, $0.6 million was recorded as a reduction to Materials, supplies and fuel stock on the Condensed Consolidated Balance Sheets and is presented as cash flows from operating activities on the Condensed Consolidated Statement of Cash Flows.
Land Easements and Rights-of-Ways
Many of PNM’s electric transmission and distribution facilities are located on lands that require the grant of rights-of-way from governmental entities, Native American tribes, or private parties. PNM has completed several renewals of rights-of-way, the largest of which is a renewal with the Navajo Nation. PNM is obligated to pay the Navajo Nation annual payments of $6.0 million, subject to adjustment each year based on the Consumer Price Index, through 2029. PNM’s April 2024 payment for the amount due under the Navajo Nation right-of-way lease was $8.6 million, which included amounts due under the Consumer Price Index adjustment. Changes in the Consumer Price Index subsequent to January 1, 2019 are considered variable lease payments.
PNM has other prepaid rights-of-way agreements that are not accounted for as leases or recognized as a component of plant in service. PNM reflects the unamortized balance of these prepayments in other deferred charges on the Condensed Consolidated Balance Sheets and recognizes amortization expense associated with these agreements in the Condensed Consolidated Statement of Earnings over their term. As of September 30, 2024 and December 31, 2023, the unamortized balance of these rights-of-ways was $67.8 million and $56.2 million. PNM recognized amortization expense associated with these agreements of $1.1 million and $3.2 million in the three and nine months ended September 30, 2024 and $0.8 million and $2.6 million in the three and nine months ended September 30, 2023.

Fleet Vehicles and Equipment
Fleet vehicle and equipment leases commencing on or after January 1, 2019 are classified as financing leases. Fleet vehicle and equipment leases existing as of December 31, 2018 are classified as operating leases. The Company’s fleet vehicle and equipment lease agreements include non-lease components for insignificant administrative and other costs that are billed over the life of the agreement. At September 30, 2024, residual value guarantees on fleet vehicle and equipment leases are $0.7 million, $0.9 million, and $1.7 million for PNM, TNMP, and TXNM Consolidated.
Battery Storage Agreements
The Company has entered into various battery storage agreements for 20-year terms that have fixed payments over the life of the agreements. The Company accounts for these agreements as operating leases and records the initial lease liabilities with corresponding right-of-use assets. In addition, the Company has elected to separate lease components from non-lease components for battery storage agreements and accordingly, does not include non-lease components in the measurement of the lease liability or right-of-use asset. The non-lease components which are not included in the measurement of the lease liability or the corresponding right-of-use asset, comprise 25.5% of the value of the agreements.

The above table includes $11.8 million, $11.1 million, and $22.9 million for PNM, TNMP, and TXNM at September 30, 2024 for expected future payments on fleet vehicle and equipment leases that could be avoided if the leased assets were returned and the lessor is able to recover estimated market value for the equipment from third parties.
At September 30, 2024, the Company has various lease arrangements that have been executed but have not yet commenced, which are primarily related to battery storage agreements. The Company currently expects lease commencement dates in 2024, with lease terms expiring in 2045, and will recognize lease assets and liabilities upon lease commencement. The expected total fixed consideration to be paid for these arrangements, which includes non-lease payments, is approximately $1.1 billion over the 20-year terms of the agreements.
(14) Income Taxes
The Company makes an estimate of its anticipated effective tax rate for the year as of the end of each quarterly period within its fiscal year. In interim periods, income tax expense is calculated by applying the anticipated annual effective tax rate to year-to-date earnings before income taxes. Certain unusual or infrequently occurring items are excluded from the estimated annual rate calculation. Such items include regulatory disallowances and excess tax benefits or deficiencies related to stock awards. At September 30, 2024, TXNM, PNM, and TNMP estimated their effective income tax rates for the year ended

December 31, 2024 would be 15.44%, 14.66%, and 20.67%. The primary difference between the statutory income tax rates and the effective tax rates is the effect of the reduction in income tax expense resulting from the amortization of excess deferred federal income taxes.
During the nine months ended September 30, 2024, income tax expense calculated by applying the expected annual effective income tax rate to earnings before income taxes was further decreased by discrete items, including $2.7 million for the tax effects of regulatory disallowances at PNM and $19.5 million from the sale of NMRD at TXNM. Excess tax shortfalls related to stock awards increased tax expense by less than $0.1 million for TXNM, of which less than $0.1 million was allocated to PNM and less than $0.1 million was allocated to TNMP.
Beginning February 2018, PNM’s NM 2016 Rate Case reflected the reduction in the federal corporate income tax rate resulting from enactment of legislation commonly known as the Tax Cuts and Jobs Act (the “Tax Act”), including amortization of excess deferred federal income taxes. In accordance with the order in that case, PNM is returning the protected portion of excess deferred federal income taxes to customers over the average remaining life of plant in service as of December 31, 2017, and had been returning the unprotected portion of excess deferred federal income taxes to customers over a period of approximately twenty-three years. Pursuant to the final order in the PNM 2024 Rate Change, the remaining balance of $62.7 million of unprotected excess deferred income taxes is being returned over a five-year period. The approved settlement in the TNMP 2018 Rate Case includes a reduction in customer rates to reflect the impacts of the Tax Act beginning on January 1, 2019. TXNM, PNM, and TNMP will amortize federal excess deferred income taxes of $23.3 million, $20.7 million, and $2.6 million in 2024. See additional discussion of the impacts of the Tax Act in Note 18 of the Notes to Consolidated Financial Statements in the 2023 Annual Reports on Form 10-K.
(15) Related Party Transactions
TXNM, PNM, TNMP, and NMRD are considered related parties, as is PNMR Services Company, a wholly-owned subsidiary of TXNM that provides corporate services to TXNM and its subsidiaries in accordance with shared services agreements. These services are billed at cost on a monthly basis to the business units. In addition, PNM purchases renewable energy from certain NMRD-owned facilities at a fixed price per MWh of energy produced.

(16) Equity Method Investment
As discussed in Note 21 of the Company’s 2023 Annual Reports on Form 10-K, PNMR Development and AEP OnSite Partners created NMRD in September 2017 to pursue the acquisition, development, and ownership of renewable energy generation projects, primarily in the state of New Mexico. On February 27, 2024, PNMR Development and AEP Onsite Partners sold their respective interests in NMRD. PNMR Development received net proceeds of $117.0 million and recognized an after-tax gain of $4.4 million, which includes the recognition of deferred investment tax credits of $15.7 million.
In the nine months ended September 30, 2024 and 2023, PNMR Development and AEP OnSite Partners each made cash contributions to NMRD of $12.6 million and $25.8 million for its construction activities.
Until the sale closing on February 27, 2024, TXNM presented its share of net earnings from NMRD in Other income on the Condensed Consolidated Statements of Earnings. Summarized financial information for NMRD through the closing date of the sale is as follows:

(17) Goodwill
The excess purchase price over the fair value of the assets acquired and the liabilities assumed by TXNM for its 2005 acquisition of TNP Enterprises, Inc. and Subsidiaries (“TNP”) was recorded as goodwill and was pushed down to the businesses acquired. In 2007, the TNMP assets that were included in its New Mexico operations, including goodwill, were transferred to PNM. TXNM’s reporting units that currently have goodwill are PNM and TNMP.
The Company evaluates its goodwill for impairment annually at the reporting unit level or more frequently if circumstances indicate that the goodwill may be impaired. Application of the impairment test requires judgment, including the identification of reporting units, assignment of assets and liabilities to reporting units, and determination of the fair value of each reporting unit.
In certain circumstances an entity may perform a qualitative analysis to conclude that the goodwill of a reporting unit is not impaired. Under a qualitative assessment an entity considers macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, other relevant entity-specific events affecting a reporting unit, as well as whether a sustained decrease (both absolute and relative to its peers) in share price has occurred. An entity considers the extent to which each of the adverse events and circumstances identified could affect the comparison of a reporting unit’s fair value with its carrying amount. An entity places more weight on the events and circumstances that most affect a reporting unit’s fair value or the carrying amount of its net assets. An entity also considers positive and mitigating events and circumstances that may affect its determination of whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. An entity evaluates, on the basis of the weight of evidence, the significance of all identified events

and circumstances in the context of determining whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. A quantitative analysis is not required if, after assessing events and circumstances, an entity determines that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount.
In other circumstances, an entity may perform a quantitative analysis to reach the conclusion regarding impairment with respect to a reporting unit. An entity may choose to perform a quantitative analysis without performing a qualitative analysis and may perform a qualitative analysis for certain reporting units, but a quantitative analysis for others. The first step of the quantitative impairment test requires an entity to compare the fair value of the reporting unit with its carrying value, including goodwill. If, as a result of this analysis, the entity concludes there is an indication of impairment in a reporting unit having goodwill, the entity is required to perform the second step of the impairment analysis, determining the amount of goodwill impairment to be recorded. The amount is calculated by comparing the implied fair value of the goodwill to its carrying amount. This exercise would require the entity to allocate the fair value determined in step one to the individual assets and liabilities of the reporting unit. Any remaining fair value would be the implied fair value of goodwill on the testing date. To the extent the recorded amount of goodwill of a reporting unit exceeds the implied fair value determined in step two, an impairment loss would be reflected in results of operations.
TXNM periodically updates its quantitative analysis for both PNM and TNMP. The use of a quantitative approach in a given period is not necessarily an indication that a potential impairment has been identified under a qualitative approach.
When TXNM performs a quantitative analysis for PNM or TNMP, a discounted cash flow methodology is primarily used to estimate the fair value of the reporting unit. This analysis requires significant judgments, including estimations of future cash flows, which is dependent on internal forecasts, estimations of long-term growth rates for the business, and determination of appropriate weighted average cost of capital for the reporting unit. Changes in these estimates and assumptions could materially affect the determination of fair value and the conclusion of impairment.
When TXNM performs a qualitative or quantitative analysis for PNM or TNMP, TXNM considers market and macroeconomic factors including changes in growth rates, changes in the Weighted Average Cost of Capital (“WACC”), and changes in discount rates. TXNM also evaluates its stock price relative to historical performance, industry peers, and to major market indices, including an evaluation of TXNM’s market capitalization relative to the carrying value of its reporting units.
For its annual evaluations performed as of April 1, 2024, TXNM performed a quantitative analysis for the PNM reporting unit and a qualitative analysis for the TNMP reporting unit. The quantitative analysis, discussed above, indicated that the fair value of the PNM reporting unit, which has goodwill of $51.6 million, exceeded its carrying value by approximately 54%. The qualitative analysis, in addition to the typical considerations discussed above, considered changes in the Company’s expectations of future financial performance since the April 1, 2020 quantitative analysis and the previous qualitative analyses through April 1, 2023 performed for TNMP. This analysis considered events specific to TNMP such as the potential impacts of legal and regulatory matters discussed in Note 11 and Note 12. Based on an evaluation of these and other factors, the Company determined it was not more likely than not that the April 1, 2024 carrying values of PNM and TNMP exceeded their fair value. Since the April 1, 2024 annual evaluation, there have been no events or indications that the fair values of the reporting units with recorded goodwill have decreased below their carrying values.
For its annual evaluations performed as of April 1, 2023, TXNM performed a qualitative analysis for both the PNM and TNMP reporting units. In addition to the typical considerations discussed above, the qualitative analysis considered changes in the Company’s expectations of future financial performance since the April 1, 2018 quantitative analysis and the previous qualitative analyses through April 1, 2022 performed for PNM, as well as the April 1, 2020 quantitative analysis and the previous qualitative analyses through April 1, 2022 performed for TNMP. This analysis considered Company specific events such as the Merger, potential impacts of legal and regulatory matters discussed in Note 11 and Note 12, including potential outcomes in PNM’s San Juan Abandonment Application, PNM’s Four Corners Abandonment Application, and PNM’s PVNGS Leased Interest Abandonment Application. The April 1, 2018 quantitative evaluations indicated the fair value of the PNM reporting unit, which has goodwill of $51.6 million, exceeded its carrying value by approximately 19%. The April 1, 2020 quantitative evaluations indicated the fair value of the TNMP reporting unit, which has goodwill of $226.7 million, exceeded its carrying value by approximately 38%. Based on an evaluation of these and other factors, the Company determined it was not more likely than not that the April 1, 2023 carrying values of PNM and TNMP exceeded their fair value.

MD&A FOR TXNM
EXECUTIVE SUMMARY
Overview and Strategy
TXNM is a holding company with two regulated utilities serving approximately 831,000 residential, commercial, and industrial customers and end-users of electricity in New Mexico and Texas. TXNM’s electric utilities are PNM and TNMP. TXNM strives to create a clean and bright energy future for customers, communities, and shareholders. TXNM’s strategy and decision-making are focused on safely providing reliable, affordable, and environmentally responsible power built on a foundation of sustainability.
Recent Developments
System Resiliency Plan (“SRP”)
In 2023, the Texas Legislature enacted HB 2555, permitting an electric utility to seek approval of, and cost recovery for a system resiliency plan. On August 28, 2024, TNMP filed its first SRP with the PUCT designed to benefit customers through enhanced resiliency of its distribution system, as intended under HB 2555. The SRP includes approximately $600 million of capital investments and approximately $151 million of other related costs over three years. Investments in the SRP are prioritized based on customer benefit, physical protection of infrastructure, foundational investments in operational and cybersecurity technologies, wildfire risk reduction and are focused on lower-performing areas in the context of reliability. The SRP is subject to PUCT approval over 180 days as stated in Texas legislation.
2025 Rate Request
On June 14, 2024, PNM filed an application with the NMPRC for a general increase in retail electric rates. The application proposes an increase of $174.3 million in retail revenues which is comprised of a $92.2 million increase in base rates and a $82.1 million increase in revenues collected under PNM’s FPPAC and reflects an ROE of 10.45%. The proposed base rate changes would be implemented in two phases, with the first phase effective July 1, 2025 and the second phase effective January 1, 2026. The requested changes reflect recovery of needed investments across distribution, transmission, and generation facilities to ensure safe reliable delivery of electricity, increased operations and maintenance expenses to meet operational needs including wildfire risk mitigation, necessary costs to service customers associated with ESAs previously approved by the NMPRC, and adjustments to Four Corners depreciation rates to recover remaining plant investments through July 2031, the expected abandonment date of the facility.

Business Focus
To achieve its business objectives, focus is directed in key areas: Safe, Reliable and Affordable Power; Utility Plant and Strategic Investments; Environmentally Responsible Power; and Customer, Stakeholders, and Community Engagement. The Company works closely with its stakeholders to ensure that resource plans and infrastructure investments benefit from robust public dialogue and balance the diverse needs of our communities. Equally important is the focus of TXNM’s utilities on customer satisfaction and community engagement.
Safe, Reliable, and Affordable Power
Safety is the first priority of our business and a core value of the Company. TXNM utilizes a Safety Management System to provide clear direction, objectives and targets for managing safety performance and minimizing risks and empowers employees to “Be the Reason Everyone Goes Home Safe”.
TXNM measures reliability and benchmark performance of PNM and TNMP against other utilities using industry-standard metrics, including System Average Interruption Duration Index (“SAIDI”) and System Average Interruption Frequency Index (“SAIFI”). PNM’s and TNMP’s investment plans include projects designed to support reliability and reduce the amount of time customers are without power.
TXNM and its utilities are aware of the important roles they play in enhancing economic vitality in their service territories. Management believes that maintaining strong and modern electric infrastructure is critical to ensuring reliability and supporting economic growth. When contemplating expanding or relocating their operations, businesses consider energy affordability and reliability to be important factors. PNM and TNMP strive to balance service affordability with infrastructure investment to maintain a high level of electric reliability and to deliver a safe and superior customer experience. Investing in PNM’s and TNMP’s infrastructure is critical to ensuring reliability and meeting future energy needs. Both utilities have long-established records of providing customers with safe and reliable electric service.
PNM participates in the EIM, a real-time wholesale energy trading market operated by the CAISO, that enables participating electric utilities to buy and sell energy. The EIM aggregates the variability of electricity generation and load for multiple balancing authority areas and utility jurisdictions. In addition, the EIM facilitates greater integration of renewable resources through the aggregation of flexible resources by capturing diversity benefits from the expanding geographic footprint and the expanded potential uses for those resources. The NMPRC approved collection of PNM’s regulatory asset to recover the initial capital investments and implementation and ongoing costs necessary to participate in the EIM in the 2024 Rate Change final order. PNM passes the cost savings through to customers under PNM’s FPPAC.
PNM joined the Western Resource Adequacy Program (“WRAP”) in April 2023 to bolster PNM’s preparations for times of critical need. WRAP is a first-of-its-kind program in the West that adds a region-wide coordination between power providers for assessing and addressing resource adequacy. This step helps ensure regional resource availability is visible and coordinated in the event PNM customers are critically impacted by a resource emergency. WRAP is currently in the non-binding phases of the program, which is expected to continue through the summer of 2027.
On May 1, 2024, PNM filed its updated WMP and its PSPS Plan with the NMPRC. The plans enhance Company wildfire prevention efforts and identify conditions for preventive shutoffs. PNM’s WMP addresses the increasing severity and frequency of extreme weather events and increasing wildfire risk and is focused on situational awareness, field personnel safety practices and operational wildfire mitigation strategies to prevent the accidental ignition of wildfires. PNM’s PSPS Plan is designed to proactively de-energize electrical facilities in identified areas of extreme wildfire risk under certain conditions to reduce the potential of those electrical facilities becoming a wildfire ignition source or contributing to the spread of wildfires.
Utility Plant Investments
During the 2022 and 2023 periods, PNM and TNMP together invested $1.9 billion in utility plant, including transmission and distribution systems, substations, power plants, and nuclear fuel. Investment plans emphasize new investments in transmission and distribution infrastructure to support growing demand with grid reliability and resilience and to deliver clean energy. The Company has been improving the diversification of its rate base among regulatory jurisdictions, moving TNMP and FERC transmission rate base to over half of the consolidated rate base.
Investments at TNMP support the continued high growth across each region of its service territory. Economic growth across Texas continues to push the demands on TNMP’s system to new levels, including a new system peak in August 2024. Additionally, the Texas legislature in 2023 passed a series of bills aimed at encouraging investments to enhance grid reliability and resilience. The PUCT has developed, and continues to develop, rules associated with the new legislation. TNMP will submit filings for investments and recovery in accordance with these new rules in addition to the existing rate recovery mechanisms.

PNM has also experienced growing demand, including a new system peak recorded in 2023. PNM investments are aimed at advancing the infrastructure beyond its original architecture to a more flexible and redundant system accommodating growing amounts of intermittent and distributed generation resources and integrating evolving technologies that provide long-term customer value. New Mexico’s clean energy future depends on a reliable, resilient, secure grid to deliver an evolving mix of energy resources to customers. In addition, projects included in the approved Grid Modernization Application improve customers’ ability to customize their use of energy and modernize PNM’s electric grid through infrastructure and technology improvements. Under New Mexico legislation for grid modernization, the approved investments will be recovered under a rate rider.
At PNM, an increase in transmission investments also supports growing transmission demands across the system and are recovered through an annual FERC formula rate mechanism based on a usage-based system allocation.
See the subheading Capital Requirements included in the full discussion of Liquidity and Capital Resources below for additional discussion of the Company’s projected capital requirements.
Integrated Resource Plan
NMPRC rules require that investor-owned utilities file an IRP every three years. The IRP is required to cover a 20-year planning period and contain an action plan covering the first three years of that period. On December 15, 2023, PNM filed its 2023 IRP with a continued focus on a carbon-free energy system by 2040. The plan highlights the need for the significant sustained addition of resources over the next two decades, replacing retiring or expiring capacity, meeting concurrent load growth, while reducing the carbon intensity of PNM’s portfolio. On April 4, 2024, the NMPRC accepted PNM’s 2023 IRP. See Note 12.
Superior Customer Experience
The Company strives to deliver a superior customer experience. In 2024, PNM continues in-person engagements with residential and business customers through customer advisory councils. These engagements have helped PNM to build and improve customer relationships and have provided PNM with valuable customer insights to gauge customer interest levels towards programs and services to be highly customer centric. Additionally, PNM continues to focus its efforts to enhance the customer experience through customer service improvements, including enhanced digital payment options, strategic customer outreach, and improved communications. These efforts are supported by market research to understand the varying needs of customers, identifying and establishing valued services and programs, and proactively communicating and engaging with customers. In 2024, PNM and the electric utility industry continue to experience a decline in customer satisfaction as measured by J.D. Power. However, PNM did achieve improvements in overall JD Power performance ranking among the overall industry and in the west mid-size region.
With reliability being the primary role of a transmission and distribution service provider in Texas’ deregulated market, TNMP continues to focus on keeping end-users updated about interruptions and to encourage consumer preparation when severe weather is forecasted. In both 2021 and 2022, TNMP provided 30-person teams in support of other utilities that experienced significant damage to their transmission and distribution system as a result of Hurricane Ida and Hurricane Ian. TNMP has been honored by the Edison Electric Institute, the association representing all US investor-owned electric companies, eight times since 2012 for its assistance to out-of-state utilities affected by hurricanes. TNMP has also been honored three times since 2008 for hurricane response in its own territory.
PNM continues to focus on addressing energy affordability by promoting participation in utility programs among households with high energy burden to offset high bills. PNM has implemented efforts to increase participation in low income energy efficiency programs, providing additional aid through the PNM Good Neighbor Fund, partnering with state agencies to make it easier to access funding, improving access to clean energy through expanded outreach and communication, and the implementation of low income transportation electrification programs. As a result of these communication efforts, 2,682 families in need have received emergency assistance through the PNM Good Neighbor Fund for the nine months ended September 30, 2024.
Environmentally Responsible Power
TXNM has a long-standing record of environmental stewardship. PNM’s environmental focus is in three key areas:
•Developing strategies to provide reliable and affordable power while transitioning to a 100% carbon-free generating portfolio by 2040
•Preparing PNM’s system to meet New Mexico’s increasing renewable energy requirements as cost-effectively as possible
•Increasing energy efficiency participation

Table of Contents
TXNM’s corporate website (www.txnmenergy.com) includes a dedicated section providing key environmental and other information related to PNM’s and TNMP’s operations, including information that collectively demonstrates the Company’s commitment to sustainability. This information highlights plans for PNM to be coal-free no later than 2031 and to achieve a carbon-free generating portfolio by 2040.
PNM has a Chief Sustainability Officer responsible for developing and implementing the Company’s business strategy and positions on environmental and sustainability policy issues and is charged with establishing organization-wide policies, strategies, goals, objectives and programs that advance sustainability and ensure compliance with regulations. The role serves as the Company’s primary contact with various regulatory and stakeholder agencies on environmental matters. In addition, the role leads environmental justice work, incorporating impacts to tribal, worker and affected communities and advancing ESG reporting.
PNM’s grid modernization plan is a major step forward to providing reliable, affordable and sustainable energy. As part of that plan, PNM will promote energy equity where technology like smart meters and distribution upgrades will be provided to low-income areas first in order to allow customers to gain insights into their energy usage in order to improve affordability and create fairer access to energy.
PNM has announced an agreement partnering with Sandia National Laboratories in research and development projects focused on energy resiliency, clean energy, and national security. The partnership demonstrates TXNM’s commitment to sustainability and its support of projects that further its carbon-free generation goals and plans for a reliable, resilient, and secure grid to deliver New Mexico’s clean energy future. PNM also recently joined the Electric Power Research Institute (“EPRI”) Climate READi (Resilience and Adaptation) Initiative, a three-year initiative to develop a comprehensive and consistent approach to physical climate risk and facilitate the analysis and application of appropriate climate data among all stakeholders to enhance the planning, design and operation of a resilient power system. In addition, PNM’s Time-of-Day pilot approved in the 2024 Rate Change final order incentivizes customers, through price signals, to use energy during the day when renewable generation is abundant.
The Infrastructure Investment and Jobs Act, also commonly known as the Bipartisan Infrastructure Law (“BIL”), was signed into law in 2021. This act represents a “once-in-a-generation” investment designed to modernize and upgrade America’s infrastructure. The BIL includes historic investments to upgrade the transmission and distribution systems to improve reliability and resilience, and to facilitate the deployment of more affordable and cleaner energy across the country. PNM participates in various grants including:
•A joint submission with Sandia National Laboratories on a project application to DOE for the Flexible and Innovative Transformer Technologies program. The program is for modular, hierarchical, Solid State Transformer control architecture that utilizes distributed control across individual minimal complexity, minimal component-count, AC-AC converter modules and acts as a drop-in replacement for traditional transformers. PNM is anticipating matching expected costs incurred by Sandia National Laboratories of $0.4 million;
•A $2.0 million grant awarded to the National Renewable Energy Laboratory through DOE, for a project called Protection of Inverter Dependent Transmission Systems. The project seeks to further understand the behavior of the transmission grid in response to faults in high inverter-based resource (“IBR”) scenarios and to develop technologies and protection system design strategies to maintain transmission grid reliability. PNM is anticipating a $2.0 million matching contribution, which includes providing transmission system network modeling and data, participating in gap analysis related to IBR modeling for fault study and protection design, and providing field data.
In October 2024, PNM was awarded two grants from the DOE. The first was for the Grid Resilience and Innovation Partnerships (“GRIP”) program. The award will improve grid stability and reduce customers’ electricity bills through smart grid technology, data aggregation software, and financial incentives. PNM will enable Virtual Power Plant (“VPP”) control on PNM’s power grid, enhance PNM’s control systems to integrate VPP, deploy distribution and behind-the-meter assets to enable a pilot area, and enable a VPP program between PNM and third party VPP aggregators for five substations. The grant is in partnership with the Pueblo of Santa Ana, ensuring that benefits reach disadvantaged communities in line with the objectives of the Justice 40 Initiative. The second grant awarded was in the Advanced Reliability and Resiliency Operations for Wind and Solar (“ARROWS”) program. GridBeyond Ltd, as principal grantee, will receive $3.9 million in DOE funding and PNM will provide the in-kind, $3.9 million local match. The program aims to boost confidence in renewable power investments using GridBeyond Ltd artificial intelligence (“AI”) powered distributed energy resource management system technology. The AI-powered system will be used to forecast, optimize, and control resources such as wind, solar, and batteries on PNM’s power grid in real-time, and enable GridBeyond Ltd to collect, analyze, and quantify the overall energy savings to determine how successful PNM is able to integrate these resources against a backdrop of variable renewable power output and storage.
The Inflation Reduction Act of 2022 (the “IRA”) provides benefits for TXNM and its customers by extending and enhancing clean energy incentives such as the investment tax credit and production tax credit. As the Company continues its transition away from carbon emitting sources, these credits will reduce the cost of renewable investments. In addition, the IRA includes a new production tax credit for existing nuclear facilities that is expected to create an added benefit for PNM’s
80

ownership in the carbon-free PVNGS. Other IRA provisions will encourage transportation electrification with new electric vehicle credits and added incentives for vehicle charging infrastructure.
Electric Vehicles
TXNM is building upon its goal of 100% carbon-free generation by 2040 with plans for additional emissions reductions through the electrification of its vehicle fleet. Growing the number of electric vehicles within the Company’s fleet will benefit the environment and lower fuel costs furthering the commitment to sustainability. Under the commitment, existing fleet vehicles will be replaced as they are retired with an increasing percentage of electric vehicles. The goals call for 25% of all light duty fleet purchases to be electric by 2025 and 50% to be electric by 2030.
To demonstrate TXNM’s commitment to increase the electrification of vehicles in its service territory, PNM implemented its first TEP in 2022, and received approval of its 2024-2026 TEP effective April 26, 2024. TEP supports customer adoption of electric vehicles by addressing barriers to adoption. PNM’s TEP program budget provides both residential and non-residential customers funding towards the purchase of chargers and/or behind-the-meter infrastructure, as well as customer education and outreach on EV-specific electricity rates to encourage charging during off-peak periods. Over 25% of the program budget is dedicated to low- and moderate-income customers to plan for an equitable transition to an electrified transportation sector.
PNM participates in the National Electric Highway Coalition, which plans to build fast-charging ports along major U.S. travel corridors. The coalition, with approximately 50 investor-owned electric companies is committed to providing EV fast charging ports that will allow the public to drive EVs with confidence throughout the country’s major roadways. To support this initiative, PNM’s TEP program includes the installation of a charging network along major roadways in New Mexico.
Renewable Energy
PNM’s utility-owned solar capacity, as well as solar, wind, and geothermal renewable procurements in service as of September 30, 2024, have a total net generation capacity of 1,647 MW in addition to 232 MW of utility-owned battery storage and battery storage agreements. In addition to PNM’s owned solar facilities, PNM also has a customer distributed solar generation program that represented 302.4 MW at September 30, 2024. The NMPRC has approved plans for PNM to procure energy and RECs from additional resources to serve retail customers and a data center located in PNM’s service territory, including the portfolio to replace SJGS and the PVNGS Leased Interest Abandonment Application. PNM’s approved resource plans have a generation capacity of 1,810 MW and are expected to be in operation before summer 2026. The majority of these resources are key means for PNM to meet the RPS and related regulations that require PNM to achieve prescribed levels of energy sales from renewable sources, including those set by the ETA, without exceeding cost requirements. For additional discussion of the ETA and 2026 Resource Application see Notes 11 and 12.
PNM will continue to procure renewable resources while balancing the impact to customers’ electricity costs in order to meet New Mexico’s escalating RPS and carbon-free resource requirements.
Energy Efficiency
Energy efficiency plays a significant role in helping to keep customers’ electricity costs low while meeting their energy needs and is one of the Company’s approaches to supporting environmentally responsible power. PNM’s and TNMP’s energy efficiency and load management portfolios continue to achieve robust results. In 2023, incremental energy saved as a result of new participation in PNM’s portfolio of energy efficiency programs was 92 GWh. This is equivalent to the annual consumption of approximately 12,781 homes in PNM’s service territory. PNM’s load management and annual energy efficiency programs also help lower peak demand requirements. In 2023, TNMP’s incremental energy saved as a result of new participation in TNMP’s energy efficiency programs is estimated to be approximately 17 GWh. This is equivalent to the annual consumption of approximately 2,296 homes in TNMP’s service territory. TNMP’s high-performance homes residential new construction energy efficiency program has earned the Energy Star Partner of the Year award for 8 years, including 6 years receiving the Sustained Excellence Award, recognizing long-term commitment to fighting climate change and protecting public health through energy efficiency. For information on PNM’s and TNMP’s energy efficiency filing with the NMPRC and PUCT see Note 12.
Water Conservation and Solid Waste Reduction
PNM continues its efforts to reduce the amount of fresh water used to make electricity (about 45% more efficient than in 2005). Continued growth in PNM’s fleet of solar and wind energy sources, energy efficiency programs, and innovative uses of air-cooling technology have contributed to this reduction. Water usage has continued to decline as PNM has substituted less fresh-water-intensive generation resources to replace SJGS. As the Company moves forward with its mission to achieve 100% carbon-free generation by 2040, it expects that more significant water savings will be gained. Shutting down SJGS in 2022 and Four Corners in 2031 will allow the Company to reach our goals for reduced freshwater use at 80% by 2035 and 90% by 2040 from 2005 levels. Focusing on responsible stewardship of New Mexico’s scarce water resources improves PNM’s water-

resilience in the face of persistent drought and ever-increasing demands for water to spur the growth of New Mexico’s economy.
In addition to the above areas of focus, the Company is working to reduce the amount of solid waste going to landfills through increased recycling and reduction of waste. In 2023, 20 of the Company’s 21 facilities met or exceeded the solid waste diversion goal of a 65% diversion rate. The Company expects to continue to do well in this area in the future.
Stakeholder and Community Engagement
The Company is committed to fostering relationships with its customers, stakeholders, and communities. Through outreach, collaboration, and various community-oriented programs, the Company has demonstrated a commitment to building productive relationships with stakeholders, including customers, community partners, regulators, intervenors, legislators, and shareholders. Local relationships and one-on-one communications remain two of the most valuable ways both PNM and TNMP connect with their stakeholders. Both companies maintain long-standing relationships with governmental representatives and key electricity consumers to ensure that these stakeholders are updated on Company investments and initiatives. Key electricity consumers also have dedicated Company contacts that support their important service needs.
The Company utilizes a number of communications channels and strategic content to serve and engage its many stakeholders. PNM’s website provides the details of major regulatory filings, including general rate requests, as well as the background on PNM’s efforts to maintain reliability, keep prices affordable, and protect the environment. TNMP’s website provides information on customized energy efficiency programs and TNMP rates, in addition to other community outreach information. The Company’s website is also a resource for information about PNM’s operations and community outreach efforts, including plans for building a sustainable energy future for New Mexico and to transition to a carbon-free generating portfolio by 2040. PNM also leverages social media in communications with customers on various topics such as education, outage alerts, safety, customer service, and PNM’s community partnerships in philanthropic projects. As discussed above, TXNM’s corporate website includes a dedicated section providing additional information regarding the Company’s commitment to sustainability.
During the three years ended December 31, 2023, corporate giving contributed $12.5 million to civic, educational, environmental, tribal communities, low income, and economic development organizations. During 2023, corporate giving has maintained a strategic focus on these pillars and continues to highlight corporate citizenship through active involvement with sponsorships demonstrating TXNM’s commitment to the community. In 2023, this corporate giving included $1.0 million to support New Mexico high school students and their ability to participate in electric trade programs. In the third quarter of 2023, TXNM shareholders donated $0.6 million to a newly created PNM Summer Heat Bill Help Fund which delivered crucial relief to low and moderate income customers struggling to pay their electric bills during the record-breaking 2023 summer heatwave and $0.5 million was given to the PNM Good Neighbor Fund.
Additionally, the PNM Resources Foundation (the “Foundation”) has provided an annual average of $1.4 million in grant funding over the past three years across New Mexico and Texas. In 2023, the Foundation celebrated its 40th year of serving community needs highlighting education, inclusion, the environment and community vitality and awarded $0.7 million to 44 organizations in New Mexico and Texas. Throughout 2024, the Foundation has focused on grants for nontraditional pathways to education and grants for the environment. These grants help nonprofits innovate or sustain programs to grow and develop their mission, develop and implement environmental programs, and provide educational opportunities. The Foundation continues to expand its matching and volunteer grant programs and the annual amount of matching donations available to each of its employees. The Foundation has also approved an increase to the amount awarded to employees, through the employee crisis management fund, who have been affected by the wildfires, floods and hurricanes. In response to the South Fork and Salt wildfires that have caused devastation in the Ruidoso and Mescalero Apache Tribe communities, PNM and the Foundation have donated to the Ruidoso Fire Emergency Action Fund, hosted by the Community Foundation of Southern New Mexico. PNM is also collaborating with community foundations to help support the effort and direct funds where they are most needed. In September 2024, TNMP sent employees to assist in restoring power to those communities impacted by Hurricane Helene. To support our team members impacted by Hurricane Beryl, the Foundation has increased the employee crisis fund, which is available to help our employees with financial support for catastrophic emergencies and basic living needs during times of crises. In addition, the Company donated $25,000 to aid our customers in storm relief in the hard-hit communities.
The Company is also committed to supporting the communities it serves in New Mexico and Texas. This support extends beyond corporate giving and financial donations from the Foundation to also include collaborations on community projects, low-income customer assistance programs, and employee volunteerism.
TXNM recognizes its responsibility to support programs and organizations that enrich the quality of life across its service territories and seeks opportunities to further demonstrate its commitment in these areas as needs arise. In response to community needs, TXNM partners with other corporate funders to support nonprofits and small businesses. While its service territory does not include the Navajo Nation, PNM’s operations include generating facilities and employees in this region. The PNM Navajo Nation Workforce Training Scholarship Program provides support for Navajo tribal members and encourages the

pursuit of education and training in existing and emerging jobs in the communities in which they live. PNM has invested in paid summer college engineering internship programs for American Indian students available in the greater Albuquerque area, established the PNM Pueblo Education Scholarship Endowment to invest in higher education for Native American Indian students, and supported the development of an entrepreneur complex located in Albuquerque and operated by the Indian Pueblo Cultural Center, owned by the 19 pueblo nations of New Mexico. PNM continues to partner with the Navajo Nation in the Light up Navajo project, piloted in 2019 and modeled as a mutual aid project to connect Navajo homes without electricity to the power grid. PNM is one of 42 utilities across 16 states to participate in improving the quality of life for families by bringing electricity to over 700 homes since inception of the project. PNM has also partnered with New Mexico universities to enhance intern programs and developed a business coalition model to drive economic development through intern partnerships. PNM continues to partner with key nonprofit organizations to initiate funding and action for programs focused on diversity, equity and inclusion.
Employee volunteers are the lifeblood of a healthy corporate culture. Community giving through volunteers’ time and effort is at the heart of employee engagement. Throughout 2024, the Company held large-scale volunteer events, working alongside nonprofits, schools, and vulnerable communities throughout New Mexico and Texas. More than 600 employees in both states participated in the annual “Day of Service”, a workday event encouraging employee volunteerism and serving more than 50 organizations. Throughout the year, employees volunteer their time generously through independent volunteer activities and board participation. Employees strengthen community resilience by giving at least 9,000 volunteer hours each year to support the health, safety, and well-being of diverse communities.
Financial Focus
Earning Authorized Returns on Regulated Businesses
TXNM’s success in accomplishing its financial objectives is highly dependent on two key factors: fair and timely regulatory treatment for its utilities and the utilities’ strong operating performance. The Company has multiple strategies to achieve favorable regulatory treatment, all of which have as their foundation a focus on the basics: safety, operational excellence, and customer satisfaction, while engaging stakeholders to build productive relationships. Both PNM and TNMP seek cost recovery for their investments through general rate cases, periodic cost of service filings, and various rate riders. See Note 12.
Fair and timely rate treatment from regulators is crucial to PNM and TNMP in earning their allowed returns and critical for TXNM to achieve its financial objectives. TXNM believes that earning allowed returns is viewed positively by credit rating agencies and that improvements in the Company’s ratings could lower costs to utility customers.
The rates PNM and TNMP charge customers are subject to traditional rate regulation by the NMPRC, FERC, and the PUCT. Additional information about rate filings is provided in Note 17 of the Notes to Consolidated Financial Statements in the 2023 Annual Reports on Form 10-K.
State Regulation and Legislation
TNMP
In the 2023 Texas Legislative session several bills were passed to support utility reliability and resiliency by encouraging and protecting utility infrastructure investments. The bill with the largest near-term financial impact to TNMP is the DCRF legislation that adds a second filing per year and shortens the regulatory timeframe for the proceedings. Other bills include system resiliency and temporary mobile generation, which provide opportunities for added investment in TNMP’s service territory and reduce uncertainty around rate recovery. Another bill directs ERCOT to develop reliability plans for the Permian Basin which could result in the need for additional investments in the West Texas service territory. Additionally, the Damaging Critical Infrastructure Bill helps protect TNMP’s investments in response to criminal offenses damaging critical infrastructure facilities. These pieces of legislation demonstrate that Texas continues to encourage utility investment and prioritizes timely rate recovery. TNMP will look to prioritize investments aligned with these measures that improve the quality of service for current and future customers.
The regulatory framework in Texas strongly encourages investments into the grid by providing timely recovery through rate mechanisms outside of general rate cases. The PUCT has approved mechanisms that allow TNMP to recover capital invested in transmission and distribution projects without having to file a general rate case. The PUCT also approved rate riders that allow TNMP to recover amounts related to energy efficiency and third-party transmission costs. In August 2024, TNMP filed its first resiliency plan under the new rules implementing the legislation passed in 2023. An independent evaluation and development of a system resiliency plan covering three years is required in the filing. Under the rules, TNMP may choose to recover the associated capital investments under the existing TCOS and DCRF rules. The rules also allow for recovery of certain O&M costs, such as vegetation management expenditures that exceed the amount authorized for recovery in

base rates. See Note 12. TNMP also has approximately 276,000 advanced meters across its service territory, the costs of which are being recovered through base rates.
PNM
The Energy Transition Act (“ETA”)
The ETA requires utilities operating in New Mexico to have renewable portfolios equal to 40% by 2025, 50% by 2030, 80% by 2040, and 100% zero-carbon energy by 2045. The ETA also allows for the recovery of undepreciated investments and decommissioning costs related to qualifying EGUs that the NMPRC has required be removed from retail jurisdictional rates, provided replacement resources to be included in retail rates have lower or zero-carbon emissions. The ETA provides for a transition from fossil-fueled generating resources to renewable and other carbon-free resources by allowing utilities to issue securitized bonds, or “energy transition bonds,” related to the retirement of certain coal-fired generating facilities to qualified investors. See additional discussion of the ETA in Notes 11 and 12 and the issuance of Securitized Bonds in Note 7 of the Notes to Consolidated Financial Statements in the 2023 Annual Reports on Form 10-K.
2024 Rate Change
In December 2022, PNM filed the 2024 Rate Change with the NMPRC. The application proposed an increase of $63.8 million in base non-fuel revenues. The requested increase is based on a calendar year 2024 FTY and reflects an ROE of 10.25%. On January 3, 2024, the NMPRC issued a final order authorizing PNM to implement an increase in non-fuel base rates of $15.3 million, effective for service beginning January 15, 2024. Major components of the final order, included:
•A ROE of 9.26%
•A capital structure of 49.61% equity, 50.10% debt, and 0.29% preferred stock
•Finding of imprudence regarding PNM’s decision to remain in Four Corners and a remedy for the imprudence resulting in a disallowance of $81.0 million to PNM’s total Four Corners net book value.
•Approval of $51.3 million of PNM’s requested $96.3 million regulatory asset for PVNGS undepreciated investments, but disallowance of a return on the remaining $45.0 million or any CWIP associated with it.
The final order also requires that the regulatory liability associated with leased capacity at PVNGS after the Unit 1 lease expired on January 15, 2023, be returned to ratepayers over two years through a rate rider. In addition, the NMPRC approved new depreciation rates for specific gas plants, reflecting shorter useful lives, approval of PNM’s TOD pilot program, and ordered PNM to update the remedy associated with Four Corners. See Note 12.
Grid Modernization Application
On October 3, 2022, in compliance with New Mexico Grid Modernization Statute, PNM filed its Grid Modernization Application with the NMPRC. The projects included in the Grid Modernization Application improve customers’ ability to customize their use of energy and ensure that customers, including low-income customers, are a top priority and will benefit from the electricity grid consistent with the Grid Modernization Statute. PNM’s proposal to modernize its electricity grid through infrastructure and technology improvements also increases the efficiency, reliability, resilience, and security of PNM’s electric system. PNM’s application seeks approval of grid modernization investments of approximately $344 million for the first six years of a broader 11-year strategy. The proposed Grid Modernization Rider would recover capital costs, operating expenses, and taxes associated with the investments included in the Grid Modernization Application. On August 16, 2024, the hearing examiner in the case issued a RD. The RD largely approved PNM’s application with minor modifications, including limiting to a return of its undepreciated costs of legacy meters and conditioned approval upon PNM accelerating the deployment schedule following a final order. On October 17, 2024, the NMPRC issued a final order adopting the RD but removed the accelerated deployment schedule. See Note 12.
2026 Resource Application
On October 25, 2023, PNM filed an application with the NMPRC seeking approval of resources to be available for the 2026 summer peak. The application included a request for approval of a 100 MW solar PPA and three battery storage agreements of 100 MW, 100 MW, and 50 MW. In addition, PNM was seeking approval of a CCN for a 60 MW battery storage system to be owned by PNM. The resources were deemed necessary for PNM to safely and reliably meet its projected system load. On May 30, 2024, the NMPRC approved PNM’s requested resources in its entirety.

Table of Contents
PNM Rate Riders and other
The NMPRC has approved PNM recovering fuel costs through the FPPAC, as well as rate riders for renewable energy, energy efficiency, and the TEP. These mechanisms allow for more timely recovery of investments. PNM’s Grid Modernization Application includes proposals for installation and deployment of advanced metering infrastructure investments and recovery under a rate rider permitted by New Mexico legislation. See Note 12.
FERC Regulation
Rates PNM charges wholesale transmission customers are subject to traditional rate regulation by FERC. Rates charged to wholesale electric transmission customers, other than customers on the Western Spirit Line, are based on a formula rate mechanism pursuant to which rates for wholesale transmission service are calculated annually in accordance with an approved formula. The formula includes updating cost of service components, including investment in plant and operating expenses, based on information contained in PNM’s annual financial report filed with FERC, as well as including projected transmission capital projects to be placed into service in the following year. The projections included are subject to true-up. Certain items, including changes to return on equity and depreciation rates, require a separate filing to be made with FERC before being included in the formula rate.
Delivering At or Above Industry-Average Earnings and Dividend Growth
TXNM’s financial objective to deliver at or above industry-average earnings and dividend growth enables investors to realize the value of their investment in the Company’s business. Earnings growth is based on ongoing earnings, which is a non-GAAP financial measure that excludes from GAAP earnings certain non-recurring, infrequent, and other items that are not indicative of fundamental changes in the earnings capacity of the Company’s operations. TXNM uses ongoing earnings to evaluate the operations of the Company and to establish goals, including those used for certain aspects of incentive compensation, for management and employees.
TXNM targets a dividend payout ratio in the 50% to 60% range of its ongoing earnings. TXNM expects to provide at or above industry-average dividend growth in the near-term. The Board will continue to evaluate the dividend on an annual basis, considering sustainability and growth, capital planning, and industry standards.
The Board approved the following increases in the indicated annual common stock dividend:

Approval Date |  | Percent Increase
December 2022 |  | 5.8%
December 2023 |  | 5.4%

Maintaining Investment Grade Credit Ratings
The Company is committed to maintaining investment grade credit ratings in order to reduce the cost of debt financing and to help ensure access to credit markets, when required. On January 15, 2024, S&P revised TXNM, PNM, and TNMP’s outlook to stable from positive. See the subheading Liquidity included in the full discussion of Liquidity and Capital Resources below for the specific credit ratings for TXNM, PNM, and TNMP. All of the credit ratings issued by both Moody’s and S&P on the Company’s debt continue to be investment grade.
Economic Factors
TNMP – In the three and nine months ended September 30, 2024, TNMP experienced an increase of 4.3% and 2.3% in volumetric weather normalized retail load compared to 2023. Weather normalized demand-based load, excluding retail transmission consumers increased 2.6% and decreased 0.9% in the three and nine months ended September 30, 2024 compared to 2023.
PNM – In the three and nine months ended September 30, 2024, PNM experienced an increase of 0.9% and 0.7% in weather normalized residential load. Weather normalized commercial load experienced an increase of 0.4% and 0.3% compared to 2023. In addition, PNM experienced an increase in industrial load of 15.5% and 11.1% compared to 2023.
The Company is closely monitoring the impacts on the capital markets of other macroeconomic conditions, including actions by the Federal Reserve to address inflationary concerns or other market conditions, and geopolitical activity. The Company has not experienced, nor does it expect significant negative impacts to customer usage at PNM and TNMP resulting from these economic impacts. However, if current economic conditions worsen, the Company may be required to implement additional measures such as reducing or delaying operating and maintenance expenses and planned capital expenditures.

Results of Operations
Net earnings attributable to TXNM were $226.4 million, or $2.50 per diluted share in the nine months ended September 30, 2024 compared to $138.0 million, or $1.60 per diluted share in 2023. Among other things, earnings in the nine months ended September 30, 2024 benefited from rate relief approved in PNM’s 2024 Rate Change, higher transmission and distribution rates at TNMP, higher volumetric load at TNMP, higher weather normalized retail load at PNM, and increased performance on PNM’s NDT, coal mine reclamation and SJGS decommissioning investment securities. In addition, rate credits as a result of the SJGS abandonment settlement agreement decreased earnings in 2023 compared to 2024. These increases were partially offset by increased operational and maintenance expense, including higher employee related, outside services and vegetation management expenses at PNM, increased depreciation and amortization approved in PNM’s 2024 Rate Change and increased plant in service at PNM and TNMP, regulatory disallowance at PNM related to San Juan Coal Mine reclamation remeasurement, lower transmission margin at PNM, capacity arrangements at PNM, milder weather at TNMP and PNM, and higher interest charges at PNM, TNMP and Corporate and Other. Additional information on factors impacting results of operations for each segment is discussed below under Results of Operations.
Liquidity and Capital Resources
As of September 30, 2024, TXNM, PNM, and TNMP have revolving credit facilities with capacities of $300.0 million, $440.0 million, and $200.0 million. Total availability for TXNM on a consolidated basis was $468.8 million at October 25, 2024. The Company utilizes these credit facilities and cash flows from operations to provide funds for both construction and operational expenditures. TXNM also has intercompany loan agreements with each of its subsidiaries. For additional details regarding the Company’s revolving credit facilities see Note 9.
TXNM projects that its consolidated capital requirements, consisting of construction expenditures and dividends, will total $6.9 billion for 2024 - 2028, including amounts expended through September 30, 2024. These construction expenditures include TNMP’s investments to support continued high growth in system demand across TNMP’s service territories and growing encouragement for infrastructure investments from the Texas legislature to support grid reliability and resilience. PNM’s capital initiatives for investments in transmission and distribution infrastructure to deliver clean energy, enhance customer satisfaction, and increase grid resilience. Construction expenditures also include investments proposed in PNM’s Grid Modernization Application and TNMP’s SRP.
To fund capital spending requirements to meet growth that balances earnings goals, credit metrics and liquidity needs, the Company has entered into a number of other financing arrangements. A complete listing of current financing arrangements is contained in Note 9 and Note 7 of the Notes to Consolidated Financial Statements in the 2023 Annual Reports on Form 10-K.
After considering the effects of these financings and the Company’s short-term liquidity position as of October 25, 2024, the Company has consolidated maturities of long-term and short-term debt aggregating approximately $880.0 million through October 2025. In addition to internal cash generation, the Company anticipates that it will be necessary to obtain additional long-term financing in the form of debt refinancing, new debt issuances, and/or new equity in order to fund its capital requirements during the 2024-2028 period. The Company currently believes that its internal cash generation, existing credit arrangements, and access to public and private capital markets will provide sufficient resources to meet the Company’s capital requirements for at least the next twelve months. As of September 30, 2024 and October 25, 2024, the Company was in compliance with its debt covenants.

Segment Information
The following discussion is based on the segment methodology that TXNM’s management uses for making operating decisions and assessing performance of its various business activities. See Note 2 for more information on TXNM’s operating segments.
TNMP
Non-GAAP Financial Measures
TNMP defines utility margin as electric operating revenues less cost of energy, which consists of costs charged by third-party transmission providers. TNMP believes that utility margin provides a more meaningful basis for evaluating operations than electric operating revenues since all third-party transmission costs are passed on to consumers through a transmission cost recovery factor. Utility margin is not a financial measure required to be presented and is considered a non-GAAP measure. TNMP does not intend for utility margin to represent any financial measure as defined by GAAP however, the calculation of utility margin, as presented, most closely compares to gross margin as defined by GAAP. Reconciliations between utility margin and gross margin are presented below.

PNM
Non-GAAP Financial Measures
PNM defines utility margin as electric operating revenues less cost of energy, which consists primarily of fuel and purchase power costs. PNM believes that utility margin provides a more meaningful basis for evaluating operations than electric operating revenues since substantially all fuel and purchase power costs are offset in revenues as those costs are passed through to customers under PNM’s FPPAC. Utility margin is not a financial measure required to be presented and is considered a non-GAAP measure. PNM does not intend for utility margin to represent any financial measure as defined by GAAP however, the calculation of utility margin, as presented, most closely compares to gross margin as defined by GAAP.
Reconciliations between utility margin and gross margin are presented below.

(1) Includes special service contract for a large customer. Energy is provided by PNM for renewable energy resources to match the energy and capacity requirements of the customer. PNM purchases renewable energy which is passed through to the customer under a rate rider. A special service rate is applied to customer’s energy consumption in those hours of the month when their consumption exceeds the energy production from the renewable resources.
(2) PNM purchases energy for a large customer on the customer’s behalf and delivers the energy to the customer’s location through PNM’s transmission system. PNM charges the customer for the cost of the energy as a direct pass through to the customer with only a minor impact in utility margin resulting from providing ancillary services.
(3) Includes sales for resale activity resulting from PNM’s participation in the EIM.

Financing Activities
See Note 7 of the Notes to Consolidated Financial Statements in the 2023 Annual Reports on Form 10-K and Note 9 for additional information concerning the Company’s financing activities. PNM must obtain NMPRC approval for any financing transaction having a maturity of more than 18 months. In addition, PNM files its annual informational financing filing and short-term financing plan with the NMPRC.
The Company’s ability to access the credit and capital markets at a reasonable cost is largely dependent upon its:
•Ability to earn a fair return on equity
•Results of operations
•Ability to obtain required regulatory approvals
•Conditions in the financial markets
•Credit ratings
The Company is closely monitoring the impacts on the capital markets of other macroeconomic conditions, including actions by the Federal Reserve to address inflationary concerns or other market conditions, and geopolitical activity. The Company currently believes it has adequate liquidity but cannot predict the effects of any of these macroeconomic conditions on the global, national, or local economy, including the Company’s ability to access capital in the financial markets, or on the Company’s financial position, results of operations, and cash flows.
Each of the Company’s revolving credit facilities and term loans contain a single financial covenant that requires the maintenance of a debt-to-capitalization ratio. For the TXNM agreements, this ratio must be maintained at less than or equal to 70%, and for the PNM and TNMP agreements, this ratio must be maintained at less than or equal to 65%. The Company’s revolving credit facilities, term loans, and other debt agreements generally also contain customary covenants, events of default, cross-default provisions, and change-of-control provisions. The Company is in compliance with its debt covenants.
On March 28, 2024, TNMP entered into the TNMP 2024 Bond Purchase Agreement for the sale of $285.0 million aggregate principal amount of four series of TNMP first mortgage bonds. TNMP issued the first two series on March 28, 2024, consisting of $32.0 million at a 5.26% interest rate, due March 28, 2029, and $85.0 million at a 5.55% interest rate, due March 28, 2036. The third and fourth series were issued on July 1, 2024, consisting of $40.0 million at a 5.65% interest rate, due July 1, 2039, and $128.0 million at a 5.79% interest rate, due July 1, 2054. The proceeds were used to repay $80.0 million of 4.03% TNMP FMBs, to repay borrowings under the TNMP Revolving Credit Facility, to fund capital expenditures, and for other corporate purposes.
In May 2024, TXNM entered into the TXNM 2024 ATM Program pursuant to which TXNM may sell, from time to time, up to an aggregate amount of $100.0 million of its common stock. In August 2024, subsequent to approval by shareholders to increase TXNM’s authorized shares, the Company increased the aggregate sales amount from $100.0 million to $300.0 million of its common stock, no par value, that may be sold under the TXNM 2024 ATM Program. During the second quarter of 2024, TXNM entered into a forward sales agreement with a forward purchaser relating to the sale of 262,025 shares of common stock, under the TXNM 2024 ATM Program. The initial forward sale price of $37.77 per share is subject to adjustments based on a net interest rate factor and by future dividends paid on TXNM common stock. During the third quarter of 2024, TXNM entered into forward sales agreements with forward purchasers relating to the sale of 2,196,926 shares of common stock, under the TXNM 2024 ATM Program. The Q3 2024 Forward Sale Agreements have a weighted average initial forward sale price of $40.58 per share that is subject to adjustments based on a net interest rate factor and by future dividends paid on TXNM common stock. TXNM did not receive any proceeds upon the execution of this agreement and, except in

certain specified circumstances, has the option to elect physical, cash, or net share settlement of the forward sale agreement on or before a date that is 12 months from the agreement effective dates. Refer to Note 9 for information regarding the initial forward sale price, the Company's settlement options and related accounting treatment. As of September 30, 2024, no shares have been settled under the 2024 Forward Sales Agreements.
On May 10, 2024, PNM entered into the $200.0 million PNM 2024 Term Loan. PNM used the proceeds of the PNM 2024 Term Loan to repay borrowings under the PNM Revolving Credit Facility, the PNM New Mexico Credit Facility, and for other corporate purposes. The PNM 2024 Term Loan bears interest at a variable rate, which was 6.11% at September 30, 2024, and must be repaid on or before November 10, 2025.
On June 10, 2024, TXNM issued $500.0 million aggregate principal amount of Convertible Notes in a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act. The Convertible Notes bear interest at a rate of 5.75% per year, payable semi-annually in arrears on June 1 and December 1 and mature on June 1, 2054, unless earlier converted, redeemed, or repurchased in accordance with their terms. On June 21, 2024, TXNM issued an additional $50.0 million aggregate principal amount of the Convertible Notes, pursuant to an overallotment option granted by TXNM to the initial purchasers of the $500.0 million Convertible Notes. Proceeds from the Convertible Notes were used to prepay $449.0 million of borrowings under the TXNM 2021 Delayed Draw Term Loan and $90.0 million of borrowings under the TXNM 2023 Term Loan, without penalty, and for other corporate purposes. See Note 9 for details related to the conversion rate and conditions for such conversion.
At December 31, 2023, PNM had outstanding $37.0 million of 3.00% PCRBs and $125.0 million of 1.15% PCRBs issued by the City of Farmington, New Mexico with a mandatory remarketing date of June 1, 2024 and final maturities of June 2040 and $36.0 million of 3.00% PCRBs issued by Maricopa County, Arizona with a mandatory remarketing date of June 1, 2024 and a final maturity of January 2038. On June 3, 2024, PNM remarketed these PCRBs aggregating $198.0 million to new investors at 3.875% with a mandatory tender date of June 1, 2029.
TXNM has entered into multiple hedging arrangements, with maturity dates of December 31, 2024 and December 31, 2025. See Note 9 for the related effective dates and terms of each arrangement. All of these hedging agreements establish a fixed rate for the indicated amount of variable rate debt, above which a customary spread is applied, which is subject to change if there is a change in TXNM’s credit rating. These hedge agreements have been accounted for as cash flow hedges.
Capital Requirements
TXNM’s total capital requirements consist of construction expenditures and cash dividend requirements for TXNM common stock and PNM preferred stock.
Key activities in TXNM’s current construction program include:
•Investments in transmission and distribution infrastructure
•Upgrading generation resources and delivering clean energy
•Purchasing nuclear fuel
Projected capital requirements, including amounts expended through September 30, 2024, are:

| 2024 |  | 2025-2028 |  | Total
| (In millions)
Construction expenditures | $ | 1,216.3 |  |  | $ | 5,026.9 |  |  | $ | 6,243.2 |
Dividends on TXNM common stock | 139.8 |  |  | 559.3 |  |  | 699.1 |
Dividends on PNM preferred stock | 0.5 |  |  | 2.1 |  |  | 2.6 |
Total capital requirements | $ | 1,356.6 |  |  | $ | 5,588.3 |  |  | $ | 6,944.9 |

The construction expenditure estimates are under continuing review and subject to ongoing adjustment, as well as to Board review and approval. The construction expenditures above include TNMP’s investments to support continued high growth in system demand across TNMP’s service territories and growing encouragement for infrastructure investments from the Texas legislature to support grid reliability and resilience. PNM’s capital initiatives include investments in transmission and distribution infrastructure to deliver clean energy, enhance customer satisfaction, and increase grid resilience. Construction expenditures also include investments proposed in PNM’s Grid Modernization Application and TNMP’s SRP. These investments provide for a more resilient, reliable, efficient, and decarbonized electric system. Not included in the table above are incremental expenditures for new customer growth in New Mexico and Texas, and other transmission and renewable energy expansion in New Mexico. The ability of TXNM to pay dividends on its common stock is dependent upon the ability of PNM and TNMP to pay dividends to TXNM. See Note 6 of the Notes to the Consolidated Financial Statements in the 2023 Annual

Reports on Form 10-K for a discussion of regulatory and contractual restrictions on the payment of dividends by PNM and TNMP.
During the nine months ended September 30, 2024, TXNM met its capital requirements and construction expenditures through cash generated from operations, as well as its liquidity arrangements and the borrowings discussed in Financing Activities above.
In addition to the capital requirements for construction expenditures and dividends, the Company has long-term debt and term loans that must be paid or refinanced at maturity. PNM has $3.4 million and $3.5 million in scheduled payments due for the ETBC I Securitized Bonds in February and August 2025. PNM also has $104.0 million and $250.0 million of SUNs that are due in May and August 2025. TXNM has $51.0 million outstanding under the TXNM 2021 Delayed Draw Term Loan that matures in May 2025. See Note 9 for additional information about the Company’s long-term debt and equity arrangements. The Company may also enter into new arrangements similar to the existing agreements, borrow under the revolving credit facilities, or issue new long-term debt or equity in the public or private capital markets, or a combination of these sources. The Company has from time to time refinanced or repurchased portions of its outstanding debt before scheduled maturity. Depending on market conditions, the Company may refinance other debt issuances or make additional debt repurchases in the future.
Liquidity
TXNM’s liquidity arrangements include the $300.0 million TXNM Revolving Credit Facility, the $400.0 million PNM Revolving Credit Facility, and the $200.0 million TNMP Revolving Credit Facility. On April 1, 2024, TXNM and PNM amended their respective revolving credit facilities, extending their maturity to March 30, 2029, with two one-year extension options that, if exercised, would extend the maturity to March 2031, subject to approval by a majority of the lenders. PNM also has the $40.0 million PNM New Mexico Credit Facility with a maturity of May 20, 2026. On April 1, 2024, TNMP entered into its new $200.0 million Revolving Credit Facility that has a maturity of March 30, 2029 with two one-year extension options that, if exercised, would extend the maturity to March 2031, subject to approval by a majority of the lenders. Variable interest rates under the TXNM, PNM, and TNMP revolving credit facilities are based on SOFR. The Company believes the terms and conditions of these facilities are consistent with those of other investment grade revolving credit facilities in the utility industry. The Company expects that it will be able to extend or replace these credit facilities under similar terms and conditions prior to their expirations.
The revolving credit facilities and the PNM New Mexico Credit Facility provide short-term borrowing capacity. The revolving credit facilities also allow letters of credit to be issued. Letters of credit reduce the available capacity under the facilities. The Company utilizes these credit facilities and cash flows from operations to provide funds for both construction and operational expenditures. The Company’s business is seasonal with more revenues and cash flows from operations being generated in the summer months. In general, the Company relies on the credit facilities to be the initial funding source for construction expenditures. Accordingly, borrowings under the facilities may increase over time. Depending on market and other conditions, the Company will periodically issue long-term debt and use the proceeds to reduce the borrowings under the credit facilities or refinance other debt. Information regarding the range of borrowings for each facility is as follows:

|  | Three Months Ended September 30, 2024 |  | Nine Months Ended September 30, 2024
Range of Borrowings |  | Low |  | High |  | Low |  | High
|  | (In millions)
PNM: |  |  |  |  |  |  |  |
PNM Revolving Credit Facility |  | $ | 28.5 |  |  | $ | 159.9 |  |  | $ | — |  |  | $ | 178.2 |
PNM New Mexico Credit Facility |  | 20.0 |  |  | 40.0 |  |  | — |  |  | 40.0 |
TNMP Revolving Credit Facility |  | 20.0 |  |  | 97.5 |  |  | 11.2 |  |  | 100.6 |
TXNM Revolving Credit Facility |  | 150.0 |  |  | 222.0 |  |  | 31.1 |  |  | 222.0 |

At September 30, 2024, the weighted average interest rates were 6.39% for the PNM Revolving Credit Facility, 6.20% for the PNM New Mexico Credit Facility, 5.96% for the TNMP Revolving Credit Facility, and 6.58% for the TXNM Revolving Credit Facility.
The Company currently believes that its capital requirements for at least the next twelve months can be met through internal cash generation, existing, extended, or new credit arrangements, and access to public and private capital markets as discussed above and in Note 9. The Company anticipates that it will be necessary to obtain additional long-term financing to fund its capital requirements and to balance its capital structure during the 2024-2028 period. This could include new debt and/or equity issuances. To cover the difference in the amounts and timing of internal cash generation and cash requirements, the Company intends to use short-term borrowings under its current and future liquidity arrangements or other short-term loans. Market conditions, such as rising interest rates, may raise the cost of borrowing under the Company’s current and future
102

liquidity arrangements or other variable debt. In addition, if market conditions worsen, the Company may not be able to access the capital markets or renew credit facilities when they expire. Should that occur, the Company would seek to improve cash flows by reducing capital expenditures and exploring other available alternatives.
As of October 25, 2024, ratings on the Company’s securities were as follows:

Contingent Provisions of Certain Obligations
As discussed in the 2023 Annual Reports on Form 10-K, TXNM, PNM, and TNMP have a number of debt obligations and other contractual commitments that contain contingent provisions. Some of these, if triggered, could affect the liquidity of the Company. In the unlikely event that the contingent requirements were to be triggered, TXNM, PNM, or TNMP could be required to provide security, immediately pay outstanding obligations, or be prevented from drawing on unused capacity under certain credit agreements. The contingent provisions also include contractual increases in the interest rate charged on certain of the Company’s short-term debt obligations in the event of a downgrade in credit ratings. The Company believes its financing arrangements are sufficient to meet the requirements of the contingent provisions. No conditions have occurred that would result in any of the above contingent provisions being implemented.

OTHER ISSUES FACING THE COMPANY
Climate Change Issues
Background
For the past several years, management has identified multiple risks and opportunities related to climate change, including the impacts of climate change and severe weather events, potential environmental regulation, technological innovation, and availability of fuel and water for operations, as among the most significant risks facing the Company. Accordingly, these risks are overseen by the Board in order to facilitate more integrated risk and strategy oversight and planning. Board oversight includes understanding the various challenges and opportunities presented by these risks, including the financial consequences that might result from enacted and potential federal and/or state regulation of GHG; plans to mitigate these risks; and the impacts these risks may have on the Company’s strategy. In addition, the Board approves certain procurements of grid modernization technologies and replacement resources.
Management is also responsible for assessing significant risks, developing and executing appropriate responses, and reporting to the Board on the status of risk activities. For example, management periodically updates the Board on the implementation of corporate environmental policy, and the Company’s environmental management systems, including the promotion of energy efficiency programs, and the use of renewable resources. The Board is also informed of the Company’s practices and procedures to assess the impacts of operations on the environment. The Board considers issues associated with climate change, the Company’s GHG exposures, and the financial consequences that might result from enacted and potential federal and/or state regulation of GHG. Management has published, with Board oversight, a Climate Change Report available at https://www.txnmenergy.com/esg-commitment/environment/climate_change_report.aspx that details the Company’s efforts to transition to a carbon-free generating portfolio by 2040.
As part of management’s continuing effort to monitor climate-related risks and assess opportunities, the Company has advanced its understanding of climate change by participating in the “2 Degree Scenario” planning by participating in the

Table of Contents
Electric Power Research Institute (“EPRI”) Understanding Climate Scenarios & Goal Setting Activities program. The program focused on characterizing and analyzing the relationship of individual electric utility company’s carbon emissions and global temperature goals. Activities include analyzing the scientific understanding of global emissions pathways that are consistent with limiting global warming and providing insight to assist companies in developing approaches to climate scenario planning. As PNM expands its sustainability efforts, EPRI’s environmental and climate analysis programs have also been useful in gaining a better understanding of energy and environmental policy and regulations, advanced clean energy technologies, decarbonization trends and climate impacts. In 2022, PNM joined EPRI’s Climate READi program which is a strategic initiative convening a global collaborative of electric utilities, thought leaders, scientific researchers and other key stakeholders to strengthen the power sector’s collective approach to managing climate risk to the power system. The program is a three-year initiative, through work across three concurrent workstreams, and PNM will benefit from the development of a first-of-its-kind comprehensive framework for managing physical climate risk and investment prioritization.
The Company cannot anticipate or predict the potential long-term effects of climate change or climate change related regulation on its results of operations, financial position, or cash flows.
Greenhouse Gas Emissions Exposures
In 2023, GHG emissions associated with PNM’s interests in its fossil-fueled generating plants included approximately 2.7 million metric tons of CO 2, which comprises the vast majority of PNM’s GHG emissions.
As of September 30, 2024, approximately 36% of PNM’s generating capacity, including resources owned, leased, under PPAs or battery storage agreements, all of which is located within the U.S., consisted of coal or gas-fired generation that produces GHG emissions. As PNM shifts its generation to cleaner energy resources, the Company’s output of GHG emissions continues to decrease. Many factors affect the amount of GHG emitted, including total electricity sales, plant performance, economic dispatch, and the availability of renewable resources. For example, wind generation performance from PNM’s largest single renewable energy resource, New Mexico Wind, varies each year as a result of highly seasonal wind patterns and annual wind resource variability. Similarly, if PVNGS experienced prolonged outages or if PNM’s entitlement from PVNGS were reduced, PNM might be required to utilize other power supply resources such as gas-fired generation, which could increase GHG emissions.
PNM has several programs underway to reduce or offset GHG emissions from its generation resource portfolio, thereby reducing its exposure to climate change regulation. PNM shutdown SJGS Units 2 and 3 as part of its strategy to address the regional haze requirements of the CAA. The shutdown of SJGS Units 2 and 3 resulted in a reduction of GHG emissions for the entire station of approximately 54% for 2018, reflecting a reduction of 32% of GHG emissions from the Company’s owned interests in SJGS, below 2005 levels. PNM shut down the remaining SJGS Units 1 and 4 on June 30, 2022 and September 30, 2022, respectively, resulting in additional reductions GHG emissions. Retiring PNM’s share of SJGS in 2022 resulted in a GHG emissions reduction from 2021 levels of 67% of PNM’s GHG emissions based upon 2021 GHG emissions from generation.
PNM’s utility-owned solar capacity, as well as solar, wind, and geothermal renewable procurements in service as of September 30, 2024 have a total net generation capacity of 1,647 MW in addition to 232 MW of utility-owned battery storage and battery storage agreements. The NMPRC has approved plans for PNM to procure energy and RECs from additional resources to serve retail customers and a data center located in PNM’s service territory, including the portfolio to replace SJGS and the PVNGS Leased Interest Abandonment Application. PNM’s approved resource plans have a generation capacity of 1,810 MW and are expected to be in operation before summer 2026. The majority of these resources are key means for PNM to meet the RPS and related regulations that require PNM to achieve prescribed levels of energy sales from renewable sources, including those set by the ETA, without exceeding cost requirements. Approval of these renewable energy and battery resources supports PNM’s transition to a carbon-free portfolio by 2040. These estimates are subject to change due to underlying variables, including changes in PNM’s generation portfolio, supplier’s ability to meet contractual in-service dates and complex relationships between several factors. See additional discussion of these resources in Notes 11 and 12.
PNM also has a customer distributed solar generation program that represented 302.4 MW at September 30, 2024. PNM’s distributed solar programs will generate an estimated 604.8 GWh of emission-free solar energy available this year to offset PNM’s annual production from fossil-fueled electricity generation. Under the Community Solar Act PNM will receive approximately 310 MW of capacity to provide customers the option of accessing solar energy, which includes PNM’s allocated portion from the NMPRC’s October 2024 order. PNM has offered its customers a comprehensive portfolio of energy efficiency and load management programs since 2007. PNM’s cumulative savings from these programs was approximately 7,454 GWh of electricity through 2023. Over the next 20 years, PNM projects energy efficiency and load management programs will provide the equivalent of approximately 12,900 GWh of electricity savings, which will avoid approximately 220,000 tons of CO 2 based upon projected emissions from PNM’s portfolio of resources. These estimates are subject to change because of the uncertainty of many of the underlying variables, including changes in PNM’s generation portfolio, demand for electricity, energy efficiency, and complex relationships between those variables.
105

Table of Contents
Because of PNM’s dependence on fossil-fueled generation, legislation or regulation that imposes a limit or cost on GHG could impact the cost at which electricity is produced. While PNM expects to recover any such costs through rates, the timing and outcome of proceedings for cost recovery are uncertain. In addition, to the extent that any additional costs are recovered through rates, customers may reduce their usage, relocate facilities to other areas with lower energy costs, or take other actions that ultimately could adversely impact PNM.
Other Climate Change Risks
PNM’s generating stations are located in the arid southwest. Access to water for cooling for some of these facilities is critical to continued operations. Forecasts for the impacts of climate change on water supply in the southwest range from reduced precipitation to changes in the timing of precipitation. In either case, PNM’s generating facilities requiring water for cooling will need to mitigate the impacts of climate change through adaptive measures. Current measures employed by PNM generating stations include the use of sustainable, less variable groundwater supplies, and investments in technologies such as air cooling and cooling water recycling. These types of actions will continue to be important to sustain operations.
PNM’s service areas occasionally experience periodic high winds and severe thunderstorms. TNMP has operations in the Gulf Coast area of Texas, which experiences periodic hurricanes and other extreme weather conditions. In addition to potentially causing physical damage to Company-owned facilities, which disrupts the ability to transmit and/or distribute energy, weather and other events of nature can temporarily reduce customers’ usage and demand for energy. In addition, other events influenced by climate change, such as wildfires, could disrupt Company operations or result in third-party claims against the Company. PNM has enhanced its wildfire prevention efforts and maintains a wildfire mitigation plan and a public safety power shutoff plan. TNMP has also developed a wildfire mitigation plan. However, both PNM and TNMP remain at risk for wildfires outside of their control and the resulting damages in their service areas.
EPA Regulation
In 2007, the US Supreme Court held that EPA has the authority to regulate GHG emissions under the CAA, and in 2009, EPA released its endangerment finding for GHG from new motor vehicles, stating that the atmospheric concentrations of six key greenhouse gases (CO 2, methane, nitrous oxides, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride) endanger the public health and welfare. These actions triggered new GHG permitting requirements for stationary sources, including the energy industry, under the Prevention of Significant Deterioration (“PSD”) and Title V program, although the US Supreme Court held the CAA does not authorize EPA to require a source to obtain a PSD permit solely on the basis of its potential GHG emissions.
EPA also determined that its finding of endangerment requires it to issue performance standards under Section 111 of the CAA to regulate GHG emissions from new and existing stationary sources, including fossil fuel fired electric generating units. Accordingly, in 2015, EPA issued Carbon Pollution Standards for new, modified, and reconstructed power plants (under Section 111(b)) and the Clean Power Plan for existing power plants (under Section 111(d)).
EPA’s Carbon Pollution Standards for new sources (those constructed after January 8, 2014) established separate standards for gas and coal-fired units deemed achievable through the application of what EPA determined to be the BSER demonstrated for each type of unit: efficient natural gas combined cycle technology for gas units, and partial carbon capture and sequestration for coal units. The Clean Power Plan established numeric “emission standards” for existing electric generating units based on emission reduction opportunities that EPA deemed achievable using technical assumptions for three “building blocks”: efficiency improvements at coal-fired EGUs, displacement of affected EGUs with renewable energy, and displacement of coal-fired generation with natural gas-fired generation. EPA used those “emission standards” to set state emission reduction goals that formed the basis of a trading program that relied on “generation shifting” to reduce emissions from the power sector as a whole.
Multiple states, utilities, and trade groups challenged both the Carbon Pollution Standards for new sources and the Clean Power Plan for existing sources in separate cases, and the challengers successfully petitioned the US Supreme Court for a stay of the Clean Power Plan. However, before the DC Circuit could issue an opinion regarding either the Carbon Pollution Standards or the Clean Power Plan, President Trump took office and his administration asked the court to hold both cases in abeyance while the rules were re-evaluated, which the court granted.
In 2019, EPA repealed the Clean Power Plan, promulgated the ACE Rule, and revised the implementing regulations for all emission guidelines issued under CAA Section 111(d). EPA set the BSER for existing coal-fired power plants as heat rate efficiency improvements based on a range of “candidate technologies” to be applied inside the fence-line of an individual facility. The ACE Rule was also challenged, and on January 19, 2021, the DC Circuit issued an opinion in American Lung Association and American Public Health Association v. EPA, et al. vacating the ACE Rule. While the D.C. Circuit rejected the ACE Rule, it did not reinstate the Clean Power Plan. Rather, the DC Circuit granted an EPA motion asking the court to withhold issuance of the mandate with respect to the repeal of the Clean Power Plan until EPA responds to the court’s remand in a new rulemaking action.

Table of Contents
Numerous parties sought review by the US Supreme Court and on June 30, 2022, the Court held that the “generation shifting” approach in the Clean Power Plan exceeded the powers granted to EPA by Congress, though the Court did not address the related issue of whether Section 111 of the CAA only authorizes EPA to require measures that can be implemented entirely within the fence line at an individual source. Of broader significance in administrative law, the Court’s opinion expressly invoked the major question doctrine, which requires rules involving issues of “vast economic or political significance,” to be supported by clear statutory authorization. In cases where there is no clear statement of authority, courts need not defer to the agency’s statutory interpretation on “major questions.” The decision sets legal precedent for future rulemakings by EPA and other federal regulatory agencies whereby the agency’s authority may be limited based upon similar reasoning.
The litigation over the Carbon Pollution Standards remains held in abeyance but could be reactivated by the parties upon a determination by the court that reconsideration of the rule has concluded.
In 2023, EPA published in the Federal Register proposed regulatory actions under CAA sections 111(b) and (d) to replace the Clean Power Plan and the ACE Rule, and finalized the rules on May 9, 2024. The final rules include revised new source performance standards under Section 111(b) for all new natural gas-fired combustion turbines and emission guidelines under Section 111(d) requiring states to develop standards of performance for GHG emissions from existing fossil-fuel-fired electric steam generating units. In the final rules, EPA determined that the standards for existing coal- or gas-fired steam generating units must be based on the use of either CCS (long-term) or natural gas co-firing (medium-term), or exempt from the rule via early retirement, and the standards for new combustion turbines must be based on CCS (base load), efficient simple cycle design (intermediate load), or lower-emitting fuels (low load). Over a dozen states, several industry groups and some power companies and labor unions have filed challenges to the rule at the DC Circuit. On July 19, 2024, the DC Circuit ruled that petitioners had not met the stringent requirements for a stay of the rules. Attorney generals in 25 states sent an emergency appeal to the US Supreme Court asking it to stay the final rule. On October 16, 2024, the US Supreme Court denied the petitioners’ request for stay. The final rule will remain in effect pending resolution of the ongoing challenges in the DC Circuit and any subsequent appeal to the US Supreme Court. The DC Circuit has scheduled oral argument for December 6, 2024, and indicated that it will decide the challenges during its 2024 term.
On March 26, 2024, EPA announced it was opening a non-regulatory docket and issued framing questions to gather input about ways to design a stronger, more durable approach to GHG regulation of existing gas combustion turbines. The docket was open for public comment from March 26 to May 28, 2024 and the agency held a policy forum to bring shareholders together to share ideas with EPA and others. The agency has indicated that it plans to issue a new proposal by December 2024.
In 2021, President Biden signed an executive order “Protecting Public Health and the Environment and Restoring Science to Tackle the Climate Crisis,” which instructs agency heads to review all Trump Administration actions for inconsistency with the Biden Administration’s policy “to listen to the science; to improve public health and protect our environment; to ensure access to clean air and water; to limit exposure to dangerous chemicals and pesticides; to hold polluters accountable, including those who disproportionately harm communities of color and low-income communities; to reduce greenhouse gas emissions; to bolster resilience to the impacts of climate change; to restore and expand our national treasures and monuments; and to prioritize both environmental justice and the creation of the well-paying union jobs necessary to deliver on these goals.” Agency heads were directed to consider suspending, revising or rescinding any action that is inconsistent with the stated policy. Within 30 days of the executive order, agency heads submitted to the United States Office of Management and Budget (“OMB”) a preliminary list of those actions being considered for suspension, revision or rescission that would be completed by December 31, 2021, and would be subject to OMB review. Within 90 days of the executive order, agency heads submitted to OMB an updated list of such actions that would be completed by December 31, 2025.
Federal Legislation
President Biden has indicated that climate change is a top priority for his administration. On April 22, 2021, at the Earth Day Summit, as part of the U.S.’ re-entry into the Paris Agreement, President Biden unveiled the goal to cut U.S. emissions by 50% - 52% from 2005 levels by 2030, nearly double the GHG emissions reduction target set by the Obama Administration. The 2030 goal joins President Biden’s other climate goals which include a carbon pollution-free power sector by 2035 and a net-zero emissions economy by no later than 2050.
In 2022, President Biden signed the IRA providing nearly $370 billion in climate action over the next decade. The legislation is aimed at reducing carbon emissions by investing in a variety of efforts, including tax credits for renewables, battery storage, carbon capture, and electric vehicle sales.
State and Regional Activity
Pursuant to New Mexico law, each utility must submit an IRP to the NMPRC every three years to evaluate renewable energy, energy efficiency, load management, distributed generation, and conventional supply-side resources on a consistent and comparable basis. The IRP is required to take into consideration risk and uncertainty of fuel supply, price volatility, and costs of anticipated environmental regulations when evaluating resource options to meet supply needs of the utility’s customers. The
107

Table of Contents
NMPRC requires that New Mexico utilities factor a standardized cost of carbon emissions into their IRPs using prices ranging between $8 and $40 per metric ton of CO 2 emitted and escalating these costs by 2.5% per year. Under the NMPRC order, each utility must analyze these standardized prices as projected operating costs. Reflecting the evolving nature of this issue, the NMPRC order states that these prices may be changed in the future to account for additional information or changed circumstances. Although these prices may not reflect the costs that ultimately will be incurred, PNM is required to use these prices for purposes of its IRP. PNM’s 2023 filing has a continued focus on a carbon-free energy system by 2040. The plan highlights the need for the significant sustained addition of resources over the next two decades, replacing retiring or expiring capacity, meeting concurrent load growth, while reducing the carbon intensity of PNM’s portfolio. See Note 12.
The ETA was signed into New Mexico state law and became effective in 2019. The ETA, among other things, requires that investor-owned utilities obtain specified percentages of their energy from renewable and carbon-free resources. The ETA requires utilities operating in New Mexico to have renewable portfolios equal to 40% by 2025, 50% by 2030, 80% by 2040, and 100% zero-carbon energy by 2045. Under the ETA provisions, PNM will also be required to meet a generation emission standard of no more than 400 lbs. of CO 2 per MWh beginning in 2023 and not more than 200 lbs. per MWh beginning in 2032. PNM takes this requirement into account in its resource planning, and it is expected that the standards will be met with the approved resource retirements and replacements. The ETA provides for a transition from fossil-fuel generating resources to renewable and other carbon-free resources by allowing investor-owned utilities to issue securitized bonds, or “energy transition bonds,” related to the retirement of coal-fired generating facilities to qualified investors. See additional discussion of the ETA in Note 11.
The ETA has a significant impact on PNM’s future generation portfolio. In 2022, in compliance with the ETA, the NMED announced a new rulemaking, Carbon Dioxide Emission Standards for Electric Generating Facilities, to develop carbon emission standards for new and existing electric coal-fired generating facilities. In 2022, the rule was passed which adopts new carbon emission standards for new and existing coal-fired power plants.
In 2020, the NMPRC approved PNM’s San Juan abandonment application and for the issuance of Securitized Bonds consistent with the requirements of the ETA and in 2023 PNM issued Securitized Bonds. PNM cannot predict the full impact of the ETA with respect to Four Corners. See additional discussion of PNM’s Four Corners Abandonment Application in Note 12.
International Accords
The United Nations Framework Convention on Climate Change (“UNFCCC”) is an international environmental treaty that was negotiated at the 1992 United Nations Conference on Environment and Development (informally known as the Earth Summit) and entered into force in March 1994. The objective of the treaty is to “stabilize greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system.” Parties to the UNFCCC, including the U.S., have been meeting annually in Conferences of the Parties (“COP”) to assess progress in meeting the objectives of the UNFCCC.
In 2015, the Paris Agreement was finalized during the 2015 COP. The aim of the Paris Agreement is to limit global temperature rise to two degrees Celsius above pre-industrial levels. The agreement, which was agreed to by approximately 200 parties, requires that countries submit INDCs. INDCs reflect national targets and actions that arise out of national policies and elements relating to oversight, guidance and coordination of actions to reduce emissions by all countries. In November 2014, then President Obama announced the United States’ commitment to reduce GHG, on an economy-wide basis, by 26%-28% from 2005 levels by the year 2025. The U.S. INDC was part of an overall effort by the former administration to have the U.S. achieve economy-wide reductions of around 80% by 2050. The former administration’s GHG reduction target for the electric utility industry was a key element of its INDC and was based on EPA’s GHG regulations for new, existing, and modified and reconstructed sources at that time. Thresholds for the number of countries necessary to ratify or accede to the Paris Agreement and total global GHG percentage were achieved on October 5, 2016 and the Paris Agreement entered into force on November 4, 2016. In 2017, President Trump announced that the U.S. would withdraw from the Paris Agreement. As a result of the President’s notice to the United Nations, the U.S. officially withdrew from the Paris Agreement on November 4, 2020. On January 20, 2021, President Biden signed an instrument that will allow the United States to rejoin the Paris Agreement on Climate Change. The instrument was deposited with the United Nations on January 21, 2021, and the United States officially became a party to the Agreement on February 19, 2021.
PNM has calculated GHG reductions that would result from scenarios that capture PNM’s retirement of its share of the SJGS in 2022 and assume exiting Four Corners in 2031 and PNM has set a goal to have a 100% carbon-free generating portfolio by 2040. While the Company has not conducted an independent 2 Degree Scenario analysis, our commitment to becoming 100% carbon-free by 2040 produces a carbon emissions reduction pathway that tracks within the ranges of climate scenario pathways that are consistent with limiting the global warming average to less than 2 degrees Celsius. In addition, as an investor-owned utility operating in the state of New Mexico, PNM is required to comply with the ETA, which requires utilities’ generating portfolio be 100% carbon-free by 2045. The requirements of the ETA and the Company’s goal compare favorably to the U.S. INDC of 50% to 52% carbon emissions reduction by 2030 and the Biden Administration’s goal of net-zero carbon

Table of Contents
emissions economy-wide by 2050. On April 1, 2020, the NMPRC approved PNM’s application to retire its share of SJGS in 2022.
PNM will continue to monitor the United States’ participation in the Paris Agreement and other parties’ involvement in these types of international accords, but the potential impact that such accords may have on the Company cannot be determined at this time.
Assessment of Legislative/Regulatory Impacts
The Company has assessed, and continues to assess, the impacts of climate change legislation and regulation on its business. This assessment is ongoing and future changes arising out of the legislative or regulatory process could impact the assessment significantly. PNM’s assessment includes assumptions regarding specific GHG limits; the timing of implementation of these limits; the possibility of a market-based trading program, including the associated costs and the availability of emission credits or allowances; the development of emission reduction and/or renewable energy technologies; and provisions for cost containment. Moreover, the assessment assumes various market reactions such as the price of coal and gas and regional plant economics. These assumptions are, at best, preliminary and speculative. However, based upon these assumptions, the enactment of climate change legislation or regulation could, among other things, result in significant compliance costs, including large capital expenditures by PNM, and could jeopardize the Company’s reputation as well as the economic viability of certain generating facilities. The ultimate consequences of increased stakeholder scrutiny related to climate change and environmental regulation could lead to increased costs to customers and affect results of operations, cash flows, and financial condition if the incurred costs are not fully recovered through regulated rates. Higher rates could also contribute to reduced usage of electricity. PNM’s assessment process is evolving and is too speculative at this time for a meaningful prediction of the long-term financial impact.
Transmission Issues
At any given time, FERC has various notices of inquiry and rulemaking dockets related to transmission issues pending. Such actions may lead to changes in FERC administrative rules or ratemaking policy but have no time frame in which action must be taken or a docket closed with no further action. Further, such notices and rulemaking dockets do not apply strictly to PNM but will have industry-wide effects in that they will apply to all FERC-regulated entities. PNM monitors and often submits comments taking a position in such notices and rulemaking dockets or may join in larger group responses. PNM often cannot determine the full impact of a proposed rule and policy change until the final determination is made by FERC and PNM is unable to predict the outcome of these matters.
Other Matters
See Notes 11 and 12 herein and Notes 16 and 17 of the Notes to Consolidated Financial Statements in the 2023 Annual Reports on Form 10-K for a discussion of commitments and contingencies and rate and regulatory matters.
CRITICAL ACCOUNTING POLICIES AND ESTIMATES
The preparation of financial statements in accordance with GAAP requires Company management to select and apply accounting policies that best provide the framework to report the results of operations and financial position for TXNM, PNM, and TNMP. The selection and application of those policies requires management to make difficult, subjective, and/or complex judgments concerning reported amounts of revenue and expenses during the reporting period and the reported amounts of assets and liabilities at the date of the financial statements. As a result, there exists the likelihood that materially different amounts would be reported under different conditions or using different assumptions.
As of September 30, 2024, there have been no significant changes with regard to the critical accounting policies disclosed in TXNM’s, PNM’s, and TNMP’s 2023 Annual Reports on Forms 10-K. The policies disclosed included regulatory accounting, impairments, decommissioning and reclamation costs, pension and other postretirement benefits, accounting for contingencies, and income taxes.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
The Company manages the scope of its various forms of market risk through a comprehensive set of policies and procedures with oversight by senior level management through the Risk Management Committee (“RMC”). The Board’s Finance Committee sets the risk limit parameters. The RMC has oversight over the risk control organization. The RMC is assigned responsibility for establishing and enforcing the policies, procedures, and limits and evaluating the risks inherent in proposed transactions on an enterprise-wide basis.
111

Table of Contents
The RMC’s responsibilities include:
•Establishing policies regarding risk tolerance levels and activities in each of the business segments
•Approving new types of derivatives entered into for marketing and hedging
•Reviewing and approving hedging risk activities
•Establishing policies regarding counterparty credit exposure and limits
•Authorizing and delegating transaction limits
•Reviewing and approving controls and procedures for derivative activities
•Reviewing and approving models and assumptions used to calculate mark-to-market and market risk exposure
•Proposing risk limits to the Board’s Finance Committee for its approval
•Reporting to the Board’s Audit and Finance Committees on these activities
To the extent an open position exists, fluctuating commodity prices, interest rates, equity prices, and economic conditions can impact financial results and financial position, either favorably or unfavorably. As a result, the Company cannot predict with certainty the impact that its risk management decisions may have on its businesses, operating results, or financial position.
Commodity Risk
Information concerning accounting for derivatives and the risks associated with commodity contracts is set forth in Note 7, including a summary of the fair values of mark-to-market energy related derivative contracts included in the Condensed Consolidated Balance Sheets. During the nine months ended September 30, 2024, and the year ended December 31, 2023, the Company had no commodity derivative instruments designated as cash flow hedging instruments.
Commodity contracts that meet the definition of a derivative are recorded at fair value on the Condensed Consolidated Balance Sheets. In the nine months ended September 30, 2024 and 2023, the effects of mark-to-market commodity derivative instruments had no impact to PNM’s net earnings and $0.8 million of fair value losses and $6.5 million of fair value gains have been recorded as a regulatory asset. All of the fair values as of September 30, 2024 and December 31, 2023, were determined based on prices provided by external sources other than actively quoted market prices. The net mark-to-market amounts as of September 30, 2024 were zero.
The Company manages risks associated with market fluctuations by utilizing various commodity instruments that may qualify as derivatives, including futures, forwards, options, and swaps. PNM uses such instruments to hedge its exposure to changes in the market prices of electricity and natural gas. PNM also uses such instruments under an NMPRC approved hedging plan to manage fuel and purchased power costs related to customers covered by its FPPAC.
Credit Risk
The Company is exposed to credit risk from its retail and wholesale customers, as well as the counterparties to derivative instruments. The Company conducts counterparty risk analysis across business segments and uses a credit management process to assess the financial conditions of counterparties. The following table provides information related to credit exposure by the credit worthiness (credit rating) and concentration of credit risk for wholesale counterparties, all of which will mature in less than two years.

Schedule of Credit Risk Exposure
September 30, 2024
Rating (1) | Credit Risk Exposure(2) |  | Number of Counter-parties >10% |  | Net Exposure of Counter-parties >10%
| (Dollars in thousands)
External ratings: |  |  |  |  |

Non-investment grade | — |  |  | — |  | — |
Total | $ | 2,873 |  |  |  |  | $ | 2,612 |

(1)The rating “Investment Grade” is for counterparties, or a guarantor, with a minimum S&P rating of BBB- or Moody’s rating of Baa3. The category “Internal Ratings – Investment Grade” includes those counterparties that are internally rated as investment grade in accordance with the guidelines established in the Company’s credit policy.
(2)The Credit Risk Exposure is the gross credit exposure, including long-term contracts, forward sales, and short-term sales. The gross exposure captures the amounts from receivables/payables for realized transactions, delivered and
112

Table of Contents
unbilled revenues, and mark-to-market gains/losses. Gross exposures can be offset according to legally enforceable netting arrangements but are not reduced by posted credit collateral. At September 30, 2024, TXNM held $0.2 million of cash collateral to offset its credit exposure.
Net credit risk for the Company’s largest counterparty as of September 30, 2024, was $1.6 million.
Other investments have no significant counterparty credit risk.
Interest Rate Risk
The majority of PNM’s and TNMP’s long-term debt is fixed-rate debt, which does not expose earnings to adverse changes in market interest rates. PNM and TNMP earnings are exposed to adverse changes in market interest rates when long-term debt must be refinanced, repriced or redeemed. TXNM’s debt and the revolving credit facilities of PNM and TNMP are exposed to interest rate risk to the extent variable interest rates continue to rise. The Company periodically makes plans to reduce its variable interest rate exposures through various instruments including fixed rate debt and equity and hedging arrangements like those executed by TXNM in 2022 and 2023, and otherwise expects that it will be able to extend or replace variable rate debt under similar terms and conditions prior to their expirations. Variable interest rates under the TXNM, PNM, and TNMP revolving credit facilities and term loans are based on SOFR.
At October 25, 2024, variable rate debt balances and weighted average interest rates were as follows:

Variable Rate Debt |  | Weighted Average Interest Rate |  | Balance Outstanding |  | Capacity
|  |  |  | (In thousands)
Short-term Debt: |  |  |  |  |  |
TXNM Revolving Credit Facility |  | 6.44 | % |  | $ | 173,600 |  |  | $ | 300,000 |
PNM Revolving Credit Facility |  | 6.14 |  |  | 182,000 |  |  | 400,000 |
PNM New Mexico Credit Facility |  | — |  |  | — |  |  | 40,000 |
TNMP Revolving Credit Facility |  | 5.80 |  |  | 112,500 |  |  | 200,000 |
|  |  |  | $ | 468,100 |  |  | $ | 940,000 |
Long-term Debt: |  |  |  |  |  |
TXNM 2021 Delayed-Draw Term Loan |  | 5.90 | % |  | $ | 51,000 |  |  |
TXNM 2023 Term Loan |  | 6.30 |  |  | 410,000 |  |  |
PNM 2024 Term Loan |  | 5.80 |  |  | 200,000 |  |  |
|  |  |  | $ | 661,000 |  |  |

The investments held by PNM in trusts for decommissioning and reclamation had an estimated fair value of $453.5 million at September 30, 2024, of which 15.7% were fixed-rate debt securities that subject PNM to risk of loss of fair value with increases in market interest rates. If interest rates were to increase by 50 basis points from their levels at September 30, 2024, the decrease in the fair value of the fixed-rate securities would be 1.1%, or $0.8 million.
PNM does not directly recover or return through rates any losses or gains on the securities, including equity investments discussed below, in the trusts for decommissioning and reclamation. However, the overall performance of these trusts does enter into the periodic determinations of expense and funding levels, which are factored into the rate making process to the extent applicable to regulated operations. PNM is at risk for shortfalls in funding of obligations due to investment losses, including those from the equity market risks discussed below, to the extent not ultimately recovered through rates charged to customers.
Equity Market Risk
The investments held by PNM in trusts for decommissioning and reclamation include certain equity securities at September 30, 2024. These equity securities expose PNM to losses in fair value should the market values of the underlying securities decline. Equity securities comprised 55.8% of the securities held by the trusts as of September 30, 2024. A hypothetical 10% decrease in equity prices would reduce the fair values of these funds by $25.3 million.
ITEM 4. CONTROLS AND PROCEDURES
Evaluation of disclosure controls and procedures
As of the end of the period covered by this quarterly report, each of TXNM, PNM, and TNMP conducted an evaluation, under the supervision and with the participation of its management, including its Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934). Based upon this evaluation, the Chief Executive Officer and the
113

Chief Financial Officer of each of TXNM, PNM, and TNMP concluded that the disclosure controls and procedures are effective.
Changes in internal controls over financial reporting
There have been no changes in each of TXNM’s, PNM’s, and TNMP’s internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934) during the quarter ended September 30, 2024, that have materially affected, or are reasonably likely to materially affect, each of TXNM’s, PNM’s, and TNMP’s internal control over financial reporting.

ITEM 1A. RISK FACTORS
As of the date of this report, there have been no material changes with regard to the Risk Factors disclosed in TXNM’s, PNM’s, and TNMP’s Annual Reports on Form 10-K for the year ended December 31, 2023, except as set forth below.
The impact of wildfires could negatively affect PNM’s and TNMP’s results of operations.
PNM and TNMP have large networks of electric transmission and distribution facilities. Weather conditions including severe drought, high winds, and the natural vegetation in the U.S. Southwest region and certain parts of Texas, could contribute to wildfires in or near PNM’s and TNMP’s service territories. The risk of wildfires could result in higher maintenance costs, increased insurance premiums, and the inability to maintain adequate insurance coverage. PNM and TNMP take proactive steps to mitigate wildfire risk. However, wildfire risk is always present and PNM and TNMP could be held liable for damages incurred as a result of wildfires caused, or allegedly caused, by their transmission and distribution systems. In addition, wildfires could cause damage to PNM’s and TNMP’s assets that could result in loss of service to customers or make it difficult to supply power in sufficient quantities to meet customer needs. Wildfire avoidance measures, such as intentional power interruptions, also may lead to customer claims for lost service, business interruption, and other injuries.
Failure to adequately address the risk of wildfires could also result in civil liability arising out of government enforcement actions or private claims. These actions could also result in reputational harm, which may cause stock price decreases, increased insurance premiums or the inability to maintain adequate insurance coverage, or cause certain investors and financial institutions not to purchase the Company’s debt securities or otherwise provide the Company with capital or credit on favorable terms, which may cause the cost of capital to increase. In addition, TXNM and its operating subsidiaries may underestimate the costs of litigation due to the uncertainty inherent in these matters. These events could have negative impacts on the Company’s financial position, results of operations, and cash flows.
TXNM and its subsidiaries’ substantial indebtedness could adversely affect its financial condition.
TXNM and its subsidiaries currently have a significant amount of indebtedness, including the Convertible Notes. This significant amount of indebtedness could limit TXNM’s ability to obtain additional financing for working capital, capital expenditures, acquisitions, debt service requirements, stock repurchases or other purposes. It may also increase TXNM’s vulnerability to adverse economic, market and industry conditions, limit its flexibility in planning for, or reacting to, changes in its business operations or to its industry overall, and place TXNM at a disadvantage in relation to its competitors that have lower debt levels. Any or all of the above events and/or factors could have an adverse effect on TXNM’s results of operations and financial condition.
114

Servicing TXNM and its subsidiaries’ debt requires a significant amount of cash, and it may not have sufficient cash flow from its business to pay its substantial debt.
TXNM and its subsidiaries’ ability to make scheduled payments of the principal of, to pay interest on or to refinance, its indebtedness, including the Convertible Notes, depends on its future performance, which is subject to economic, financial, competitive and other factors beyond its control. TXNM’s business may not continue to generate cash flow from operations in the future sufficient to service its debt and make necessary capital expenditures. If TXNM is unable to generate such cash flow, TXNM may be required to adopt one or more alternatives, such as selling assets, restructuring debt or obtaining additional equity capital on terms that may be onerous or highly dilutive. TXNM’s ability to refinance its indebtedness will depend on the capital markets and its financial condition at such time. TXNM may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on its debt obligations.
Despite TXNM’s current consolidated debt levels, TXNM and its subsidiaries may still incur substantially more debt or take other actions which would intensify the risks discussed above.
Despite TXNM’s current consolidated debt levels, TXNM and its subsidiaries may be able to incur substantial additional debt in the future, subject to the restrictions contained in its debt instruments, some of which may be senior indebtedness or secured debt. TXNM is not restricted under the terms of the Convertible Notes Indenture from incurring additional debt, securing existing or future debt, recapitalizing its debt or taking a number of other actions. TXNM’s Credit Agreement restricts its ability to incur additional indebtedness, including secured indebtedness, but if the TXNM Credit Agreement matures or is repaid, TXNM may not be subject to such restrictions under the terms of any subsequent indebtedness.
The conditional conversion feature of the Convertible Notes, if triggered, may adversely affect TXNM’s financial condition and operating results.
In the event the conditional conversion feature of the Convertible Notes is triggered, holders of Convertible Notes will be entitled to convert the Convertible Notes at any time during specified periods at their option. If one or more holders elect to convert their Convertible Notes, to the extent TXNM is required to pay cash to settle a portion of its conversion obligation, it could adversely affect TXNM’s liquidity. In addition, even if holders do not elect to convert their Convertible Notes, to the extent TXNM is required to pay cash to settle a portion of its conversion obligations, TXNM would be required under applicable accounting rules to reclassify all or a portion of the outstanding principal of the Convertible Notes as a current rather than long-term liability, which would result in a material reduction of its net working capital.
The accounting method for the Convertible Notes could have a material effect on TXNM’s reported financial results.
In August 2020, the Financial Accounting Standards Board issued Accounting Standards Update No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06”), which amends the accounting standards for convertible debt instruments that may be settled entirely or partially in cash upon conversion. ASU 2020-06 eliminates requirements to separately account for liability and equity components of such convertible debt instruments and eliminates the ability to use the treasury stock method for calculating diluted earnings per share for convertible instruments whose principal amount may be settled using shares. Instead, ASU 2020-06 requires (i) the entire amount of the security to be presented as a liability on the balance sheet and (ii) application of the “if-converted” method for calculating diluted earnings per share. Under the “if-converted” method, diluted earnings per share will generally be calculated assuming that all the Convertible Notes were converted solely into shares of common stock at the beginning of the reporting period, unless the result would be anti-dilutive, which could adversely affect TXNM’s diluted earnings per share. However, if the principal amount of the convertible debt security, such as the Convertible Notes, being converted is required to be paid in cash and only the excess is permitted to be settled in shares, the if-converted method will produce a similar result as the “treasury stock” method prior to the adoption of ASU 2020-06 for such convertible debt security.
ASU 2020-06 became effective for TXNM as of the start of fiscal year end 2022 and as such TXNM did not bifurcate the liability and equity components of the Convertible Notes on its balance sheet and TXNM used the if-converted method of calculating diluted earnings per share. To the extent TXNM is required to pay cash to settle the principal amount of the Convertible Notes upon conversion, with only the excess permitted to be settled in shares of TXNM’s common stock, the application of the if-converted method will produce a similar result as the treasury stock method prior to the adoption of ASU 2020-06. The effect of the treasury stock method is that the shares issuable upon conversion of such Convertible Notes are not included in the calculation of diluted earnings per share except to the extent that the conversion value of such Convertible Notes exceeds their principal amount. The requirement that the principal amount of the Convertible Notes upon conversion must be paid in cash could adversely affect TXNM’s liquidity.
TXNM cannot be sure whether other changes may be made to the current accounting standards related to the Convertible Notes, or otherwise, that could have a material effect on its reported financial results.
115

The fundamental change repurchase feature of the Convertible Notes may delay or prevent an otherwise beneficial attempt to acquire TXNM.
Certain provisions in the indenture governing the Convertible Notes may make it more difficult or expensive for a third party to acquire TXNM. For example, the Convertible Notes Indenture requires TXNM, subject to certain exceptions, to repurchase the Convertible Notes for cash upon the occurrence of a fundamental change (as defined in the Convertible Notes Indenture) and, in certain circumstances, to increase the conversion rate for a holder that converts its Convertible Notes in connection with a make-whole fundamental change (as defined in the Convertible Notes Indenture). A takeover of TXNM may trigger the requirement that TXNM repurchase the Convertible Notes and/or increase the conversion rate, which could make it more costly for a potential acquirer to engage in such takeover. Such additional costs may have the effect of delaying or preventing a takeover of TXNM that would otherwise be beneficial to investors.
ITEM 5. OTHER INFORMATION
During the three months ended September 30, 2024, no director or officer (as defined by Rule 16a-1(f) of the Exchange Act) of the Company adopted or terminated a “Rule 10b5-1 trading arrangement” or “non-Rule 10b5-1 trading arrangement,” as each term is defined in Item 408(a) of Regulation S-K.
