(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 March 31, 2023 and December 31, 2022, and the consolidated results of operations, comprehensive income, and cash flows for the three months ended March 31, 2023 and 2022. 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.

The Notes to Condensed Consolidated Financial Statements include disclosures for PNMR, PNM, and TNMP. This report uses the term “Company” when discussing matters of common applicability to PNMR, PNM, and TNMP. Discussions regarding only PNMR, PNM, or TNMP are so indicated. Certain amounts in the 2022 Condensed Consolidated Financial Statements and Notes thereto have been reclassified to conform to the 2023 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 PNMR’s, PNM’s, and TNMP’s audited Consolidated Financial Statements and Notes thereto that are included in their respective 2022 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 PNMR, PNM, and TNMP include their accounts and those of subsidiaries in which that entity owns a majority voting interest. PNM also consolidates Valencia. 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 PNMR, PNM, and TNMP include interest and income tax sharing payments, as well as equity transactions, and interconnection billings. See Note 15. All intercompany transactions and balances have been eliminated.

Dividends on Common Stock

Dividends on PNMR’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. The Board declared dividends on common stock of $0.3675 per share in February 2023 and $0.3475 per share in February 2022, which are reflected as Dividends Declared per Common Share on the PNMR Condensed Consolidated Statement of Earnings.

PNMR did not make any cash equity contributions to PNM or TNMP in the three months ended March 31, 2023 and 2022. Neither PNM nor TNMP declared or paid any cash dividends to PNMR in the three months ended March 31, 2023 and 2022.

New Accounting Pronouncements

Information concerning a recently issued accounting pronouncement that has not yet been adopted by the Company is presented below. The Company does not expect difficulty in adopting this standard by its required effective date.

Accounting Standards Update 2022-03 - Fair Value Measurement (Topic 820): Fair Value Measurements of Equity Securities Subject to Contractual Sale Restrictions

In June 2022, the FASB issued ASU 2022-03 clarifying that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the security and, therefore, is not considered in measuring fair value. The amendment also clarifies that an entity cannot, as a separate unit of account, recognize and measure a contractual sale restriction. Disclosure requirements from the amendment include disclosure of the fair value of equity securities subject to contractual sale restrictions that are reflected in the balance sheet; the nature and remaining duration of the restriction(s); and the circumstances that could cause a lapse in the restriction(s). ASU 2022-03 is effective for the Company beginning January 1, 2024 with early adoption for both interim and annual periods being permitted. ASU 2022-03 is to be applied prospectively with any adjustments recognized in earnings and disclosed on the date of adoption.

(2) Segment Information

The following segment presentation is based on the methodology that management uses for making operating decisions and assessing performance of its various business activities. A reconciliation of the segment presentation to the GAAP financial statements is provided.

PNM

PNM includes the retail electric utility operations of PNM that are subject to traditional rate regulation by the NMPRC. PNM provides integrated electricity services that include the generation, transmission, and distribution of electricity for retail electric customers in New Mexico. PNM also includes the generation and sale of electricity into the wholesale market, which includes the asset optimization of PNM's jurisdictional capacity, as well as providing transmission services to third parties. FERC has jurisdiction over wholesale power and transmission rates.

TNMP

TNMP is an electric utility providing services in Texas under the TECA. TNMP’s operations are subject to traditional rate regulation by the PUCT. TNMP provides transmission and distribution services at regulated rates to various REPs that, in turn, provide retail electric service to consumers within TNMP’s service area. TNMP also provides transmission services at regulated rates to other utilities that interconnect with TNMP’s facilities.

Corporate and Other

The Corporate and Other segment includes PNMR holding company activities, primarily related to corporate level debt and PNMR Services Company. The activities of PNMR Development and the equity method investment in NMRD are also included in Corporate and Other. Eliminations of intercompany transactions are reflected in the Corporate and Other segment.

The following tables present summarized financial information for PNMR by segment. PNM and TNMP each operate in only one segment. Therefore, tabular segment information is not presented for PNM and TNMP.

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.

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 months ended March 31, 2023 and 2022, 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 $99.6 million at March 31, 2023 and $151.4 million at December 31, 2022 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 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 $14.5 million at March 31, 2023 and $11.9 million at December 31, 2022. This contract asset is presented in Other deferred charges on the Condensed Consolidated Balance Sheet.

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. Under its OATT, PNM accepts upfront consideration for capacity reservations requested by transmission customers, which requires PNM to defer the customer’s transmission capacity rights for a specific period of time. PNM recognizes the revenue of these capacity reservations over the period it defers the customer's capacity rights. 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. PNMR'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.

(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 variable interest entity (“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 2022 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 months ended March 31, 2023 and 2022, PNM paid $5.0 million and $4.8 million for fixed charges and $1.6 million and $0.1 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.

Westmoreland San Juan Mining, LLC

As discussed in the subheading Coal Supply in Note 11, PNM purchased coal for SJGS under the SJGS CSA. PNM and Westmoreland also entered into agreements under which CCR disposal and mine reclamation services for SJGS would be provided. In 2019, Westmoreland emerged from Chapter 11 bankruptcy as a privately held company owned and operated by a group of its former creditors. Under the reorganization, the assets of SJCC were sold to Westmoreland San Juan Mining, LLC (“WSJ LLC”), a subsidiary of Westmoreland Mining Holdings, LLC. As successor entity to SJCC, WSJ LLC assumed all rights and obligations of SJCC including obligations to PNM under the SJGS CSA and to PNMR under letter of credit support agreements.

PNMR issued $30.3 million in letters of credit to facilitate the issuance of reclamation bonds required in order for SJCC to mine coal to be supplied to SJGS. As discussed above, WSJ LLC assumed the rights and obligations of SJCC, including obligations to PNMR for the letters of credit. The letters of credit support results in PNMR having a variable interest in WSJ LLC since PNMR is subject to possible loss in the event performance by PNMR is required under the letters of credit support. PNMR 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 will 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. PNMR’s analysis of its arrangements with WSJ LLC concluded that WSJ LLC had the ability to direct its mining operations and reclamation services, which are the factors that most significantly impact the economic performance of WSJ LLC. Other than PNM being able to ensure that coal was supplied in adequate quantities and of sufficient quality to provide the fuel necessary to operate SJGS in a normal manner and monitoring of reclamation activities, the mining operations and reclamation services were solely under the control of WSJ LLC, including developing mining and reclamation plans, hiring of personnel, and incurring operating and maintenance expenses. Neither PNMR nor PNM had any ability to direct or influence the mining operation or reclamation activities. PNM’s involvement through the SJGS CSA and 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. The SJGS CSA required WSJ LLC to deliver coal to fuel SJGS in exchange for payment of a set price per ton, which escalated over time for inflation. The reclamation services agreement requires WSJ LLC to perform reclamation services at a base price per activity, which escalates over time for inflation. If WSJ LLC had been able to mine or performs reclamation services more efficiently than anticipated,

its economic performance would improve. Conversely, if WSJ LLC had not been able to mine or does not perform reclamation services as efficiently as anticipated, its economic performance would be negatively impacted. Accordingly, PNMR believes WSJ LLC is the primary beneficiary and, therefore, WSJ LLC is not consolidated by either PNMR or PNM. The amounts outstanding under the letters of credit support continue to be PNMR’s maximum exposure to loss from the VIE at March 31, 2023.

(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 2022 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 is exposed to market risk for the needs of its customers not covered under the FPPAC.

PNM has entered into several agreements to purchase power from third parties in order to ensure that customer demand during the 2023 summer peak load is met. Agreements for purchases totaling 85 MW from June 1, 2023 through September 30, 2023 were not considered derivatives because there was either no notional amount due to their unit-contingent nature or qualified for a normal purchase, normal sale scope exception. Agreements totaling 375 MW were accounted for as derivative agreements and are considered economic hedges, see the table below. For additional information related to 2023 summer peak resource adequacy, see Note 12.

In 2021, PNM entered into three agreements to purchase power from third parties at a fixed price in order to ensure that customer demand during the 2022 summer peak load period was met. Two of the agreements, the purchase of 85 MW from June through September 2022 and the purchase of 40 MW for the full year of 2022, were not considered derivatives because there were no notional amounts due to the unit-contingent nature of the agreements. The third agreement for the purchase of 150 MW firm power in June and September 2022 met the definition of an economic hedge described below and was accounted for accordingly.

PNM was exposed to market risk for its 65 MW interest in SJGS Unit 4, which was held as merchant plant as ordered by the NMPRC from January 1, 2018 until September 30, 2022. PNM entered into agreements to sell power from 36 MW of that capacity to a third party at a fixed price for the period January 1, 2018 through June 30, 2022, subject to certain conditions. Under these agreements, PNM was obligated to deliver 36 MW of power only when SJGS Unit 4 was operating. In May 2022, PNM executed a new agreement to sell 50 MW of that capacity to a third party for the period from July 1, 2022 through September 30, 2022 on a system-contingent basis. These agreements were not considered derivatives because there was no notional amount due to the unit-contingent nature of the transactions.

PNM and Tri-State had a hazard sharing agreement that expired in May 2022. Under this agreement, each party sold the other party 100 MW of capacity and energy from a designated generation resource on a unit contingent basis, subject to certain performance guarantees. The agreement was accounted for as a commodity derivative. In May 2022, PNM and Tri-State entered into another hazard sharing agreement that existed on a unit contingent basis through September 30, 2022, however this agreement did not include a performance guarantee. As a result, this agreement was not considered a derivative. Both the purchases and sales were made at the same market index price. This agreement served to reduce the magnitude of

(Unaudited)

each party’s single largest generating hazard and assist in enhancing the reliability and efficiency of their respective operations. PNM passed the sales and purchases through to customers under PNM’s FPPAC.

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 three months ended March 31, 2023 and the year ended December 31, 2022, 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 and are classified between 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 liabilities. 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:

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 $0.4 million of current assets and, $27.1 million of current liabilities related to these arrangements at March 31, 2023 and $9.8 million of current assets and

$19.2 million of current liabilities at December 31, 2022 with changes in fair value recorded as regulatory assets and regulatory liabilities.

At March 31, 2023 and December 31, 2022, PNM had no amounts recognized for the legal right to reclaim cash collateral. However, amounts posted as cash collateral under margin arrangements were $2.3 million at March 31, 2023 and $10.5 million at December 31, 2022. These amounts are included in other current assets on the Condensed Consolidated Balance Sheets. At March 31, 2023 and December 31, 2022, 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 three months ended March 31, 2023 and 2022. 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. The table below presents PNM's net buy (sell) volume positions:


	Economic Hedges
	MMBTU	MWh
March 31, 2023	—	651,375
December 31, 2022	—	432,200

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 requirement 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.

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 March 31, 2023 and December 31, 2022, the fair value of investment securities included $337.7 million and $325.3 million for the NDT, $14.8 million and $14.7 million for the SJGS decommissioning trust, and $78.8 million and $77.5 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 March 31, 2023 and December 31, 2022, PNM had no available-for-sale debt securities for which carrying value exceeds fair value and there are no impairments considered to be “other than temporary” that are included in AOCI and not recognized in earnings. All gains and losses resulting from sales and changes in the fair value of equity securities are recognized immediately in earnings.

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 and Level 3 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. 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. The valuation of Level 3 investments, when applicable, requires significant judgment by the pricing provider due to the absence of quoted market values, changes in market conditions, and the long-term nature of the assets. The Company has no Level 3 investments as of March 31, 2023 and December 31, 2022. Management of the Company independently verifies the information provided by pricing services. Items recorded at fair value by PNM on the Condensed Consolidated Balance Sheets are presented below by level of the fair value hierarchy along with gross unrealized gains on investments in available-for-sale debt securities:

(8) Stock-Based Compensation

PNMR has various stock-based compensation programs, which provide restricted stock awards under the Performance Equity Plan (“PEP”). Although certain PNM and TNMP employees participate in the PNMR plans, PNM and TNMP do not have separate employee stock-based compensation plans. Certain restricted stock awards are subject to achieving performance or market targets. Other awards of restricted stock are only subject to time vesting requirements. Restricted stock expected to be awarded under the PEP for performance periods ending after 2023 no longer have market targets. Additional information concerning stock-based compensation under the PEP is contained in Note 12 of the Notes to Consolidated Financial Statements in the 2022 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 March 31, 2023, PNMR had unrecognized expense related to stock awards of $8.3 million, which is expected to be recognized over an average of 2.4 years.

The grant date fair value for restricted stock and stock awards with internal PNMR performance targets is determined based on the market price of PNMR 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.

(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 or enter into term loan 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 PNMR 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 2022 Annual Reports on Form 10-K.

On March 2, 2022, PNMR filed a shelf registration that provides for the issuance of various types of debt and equity securities. The PNMR shelf registration statement expires in March 2025.

Financing Activities

On April 28, 2023, PNM entered into an agreement (the "PNM 2023 Note Purchase Agreement") with institutional investors for the sale and issuance of $200.0 million aggregate principal amount of two series of senior unsecured notes (the “PNM 2023 SUNs”) offered in private placement transactions. The PNM 2023 SUNs were issued on April 28, 2023. PNM issued $150.0 million of the PNM 2023 SUNs at 5.51%, due April 28, 2035, and another $50.0 million at 5.92%, due April 28, 2053. Proceeds from the PNM 2023 SUNs were used to repay borrowings under the PNM Revolving Credit Facility and the PNM New Mexico Credit Facility, funding of capital expenditures and for general corporate purposes. The PNM 2023 Note Purchase Agreement includes the customary covenants discussed above. In the event of a change of control, PNM will be required to offer to prepay the PNM 2023 SUNs at par. Although there are customary change of control provisions in the PNM debt agreements, the change of control provisions in these agreements, including the PNM 2023 Note Purchase Agreement, are not triggered by the closing of the Merger. PNM has the right to redeem any or all of the PNM 2023 SUNs prior to their maturities, subject to payment of a customary make-whole premium.

On April 28, 2023, TNMP entered into an agreement (the “TNMP 2023 Bond Purchase Agreement”) with institutional investors for the sale of $185.0 million aggregate principal amount of two series of TNMP first mortgage bonds (the “TNMP 2023 Bonds”) offered in private placement transactions. TNMP issued the first series of $130.0 million of the TNMP 2023 Bonds on April 28, 2023, at a 5.01% interest rate, due April 28, 2033. The second series of $55.0 million will be issued on or before July 28, 2023, at a 5.47% interest rate, due July 28, 2053. The proceeds were used to repay borrowings under the TNMP Revolving Credit Facility and for other corporate purposes. The TNMP 2023 Bonds are subject to continuing compliance with the representations, warranties and covenants set forth in the supplemental indenture governing the TNMP 2023 Bonds. The terms of the supplemental indentures governing the TNMP 2023 Bonds include the customary covenants discussed above. In the event of a change of control, TNMP will be required to offer to prepay the TNMP 2023 Bonds at par. However, the definition of change of control in the supplemental indentures governing the TNMP 2023 Bonds will not be triggered by the close of the Merger. TNMP has the right to redeem any or all of the TNMP 2023 Bonds prior to their maturity, subject to payment of a customary make-whole premium.

On November 10, 2022, PNMR entered into a distribution agreement with BofA Securities, Inc., MUFG Securities Americas Inc. and Wells Fargo Securities, LLC, as sales agents and Bank of America, N.A., MUFG Securities EMEA plc 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 price of $200.0 million of its common stock, no par value, through the sales agents (the “PNMR 2022 ATM Program”).

During the first quarter of 2023, PNMR entered into forward sale agreements with each of Bank of America, N.A. and Wells Fargo Bank, N.A. as forward purchasers relating to the sale of 504,452 shares and 528,082 shares of common stock, respectively, under the PNMR 2022 ATM Program (the “2023 Forward Sale Agreements”). The average initial forward sale price of $48.49 per share and $48.30 per share, respectively, are subject to adjustments based on a net interest rate factor and by future dividends paid on PNMR common stock as specified in the forward sale agreements. PNMR 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 dates.

The Company expects to receive proceeds from the sale of shares upon future physical settlement(s) of the 2023 Forward Sale Agreements, in which case the Company will deliver newly issued shares to the forward purchasers in exchange for cash in an amount equal to the number of shares delivered multiplied by the then-applicable forward sale price. PNMR also has the option to net settle the agreements in cash or shares of PNMR common stock. Under a net cash settlement, under which no PNMR common stock would be issued, PNMR would receive net proceeds for a decrease in the market value of PNMR's common stock relative to the then-applicable forward sales price per share, or would owe cash in the event of an increase in the market value of PNMR common stock. Under a net share settlement, PNMR would not receive any cash proceeds and may be required to deliver a sufficient number of shares of PNMR common stock to satisfy its obligation to the forward purchasers. The number of shares to be delivered to the forward purchasers would be based on the increase in the PNMR's common stock price relative to the then-applicable forward sales price per share. The forward sale agreements meet the derivative scope exception requirements for contracts involving an entity's own equity. Until settlement of the forward sale agreements, PNMR’s EPS dilution resulting from the agreements, if any, will be determined using the treasury stock method, which will result in dilution during periods when the average market price of PNMR stock during the reporting period is higher than the applicable forward sales price as of the end of that period. As of March 31, 2023, no shares have been settled under the 2023 Forward Sale Agreements.

On May 2, 2022, PNMR entered into two separate 20-month hedging agreements for $150.0 million and $200.0 million, to hedge an equal amount of its variable rate debt, whereby it effectively established a fixed interest rate of 2.65%. On May 20, 2022, PNMR entered into a third 19-month hedging agreement for $100.0 million to hedge an equal amount of its variable rate debt, whereby it effectively established a fixed interest rate of 2.52%. On September 30, 2022, PNMR entered into two additional 15-month hedging agreements for $100.0 million each, totaling $200.0 million, to hedge an equal amount of its variable rate debt, whereby it effectively established fixed interest rates of 4.17% and 4.18%. On October 31, 2022, PNMR entered into two additional 14-month hedging agreements for $100.0 million each, totaling $200.0 million, to hedge an equal amount of its variable rate debt, whereby it effectively established fixed interest rates of 4.66% and 4.65%. On March 15, 2023, PNMR entered into an approximately 6-month hedging arrangement, effective March 17, 2023, for $150.0 million to hedge an equal amount of its variable rate debt, whereby it effectively established a fixed interest rate of 4.57%. Also on March 15, 2023, PNMR entered into two separate 12-month hedging arrangements, effective January 1, 2024, for $150.0 million each, totaling $300.0 million to hedge an equal amount of its variable rate debt, whereby it effectively established fixed interest rate of 3.57% and 3.62%. On May 4, 2023, PNMR entered into three separate 12-month hedging arrangements, effective January 1, 2024, for $100.0 million each, totaling $300.0 million to hedge an equal part of its variable rate debt, whereby it effectively established fixed interest rates of 3.32%, 3.32%, and 3.38%. All of these hedging agreements establish the fixed rate indicated for the indicated amount of variable rate debt, above which a customary spread over SOFR is applied, which is subject to change if there is a change in PNMR's credit rating.

These hedge agreements are accounted for as cash flow hedges. The fair value of these hedges was a gain of $8.7 million at March 31, 2023, $8.4 million of which is included in Other current assets and $0.3 million of which is included in Other deferred charges 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.

On April 27, 2022, TNMP entered into an agreement (the "TNMP 2022 Bond Purchase Agreement") with institutional investors for the sale of $160.0 million aggregate principal amount of two series of TNMP first mortgage bonds (the "TNMP 2022 Bonds") offered in private placement transactions. TNMP issued the first series of $65.0 million of the TNMP 2022 Bonds on May 12, 2022, at a 4.13% interest rate, due May 12, 2052, and the second series of $95.0 million of the TNMP 2022 Bonds on July 28, 2022, at a 3.81% interest rate, due July 28, 2032. The proceeds were used to repay borrowings under the TNMP Revolving Credit Facility and for other corporate purposes. The TNMP 2022 Bonds are subject to continuing compliance with the representations, warranties and covenants set forth in the supplemental indenture governing the TNMP 2022 Bonds. The terms of the supplemental indentures governing the TNMP 2022 Bonds include the customary covenants discussed above. In the event of a change of control, TNMP will be required to offer to prepay the TNMP 2022 Bonds at par. However, the definition of change of control in the supplemental indentures governing the TNMP 2022 Bonds will not be triggered by the close of the Merger. TNMP has the right to redeem any or all of the TNMP 2022 Bonds prior to their maturity, subject to payment of a customary make-whole premium.

At March 31, 2023, variable interest rates were 5.84% on the PNMR 2021 Delayed-Draw Term Loan that matures in May 2025 and 5.60% on the PNM 2022 Delayed-Draw Term Loan that matures in February 2024.

Short-term Debt and Liquidity

Currently, the PNMR Revolving Credit Facility has a financing capacity of $300.0 million and the PNM Revolving Credit Facility has a financing capacity of $400.0 million. On May 20, 2022, both PNMR and PNM extended the facilities to October 31, 2024 with two one-year extension options that, if exercised, would extend the maturity through October 2026, subject to approval by a majority of the lenders. On January 26, 2023 PNMR and PNM exercised one of the one-year extension options in their respective agreements, extending their maturities through October 2025; provided that, effective November 1, 2024, the capacity of the PNMR Revolving Credit Facility will adjust to $285.0 million and the PNM Revolving Credit Facility will adjust to $380.0 million because one lender in each facility did not agree to the one-year extension through October 2025. Also on May 20, 2022, the $40.0 million PNM New Mexico Credit Facility was extended to May 20, 2026. On March 11, 2022, the TNMP Revolving Credit Facility, with a capacity of $75.0 million secured by $75.0 million aggregate principal amount of TNMP first mortgage bonds was amended to extend the maturity to September 23, 2024, with two one-year extension options that, if exercised, would extend the maturity to September 2026, subject to approval by a majority of the lenders. The amended TNMP Revolving Credit Facility also contained an accordion feature that would allow TNMP to increase the size of the revolver from $75.0 million to $100.0 million, subject to certain conditions. On May 13, 2022, TNMP exercised the accordion feature and increased the capacity of the TNMP Revolving Credit Facility to $100.0 million, secured by $100.0 million aggregate principal amount of TNMP first mortgage bonds. On January 26, 2023, TNMP exercised one of the one-year extension options on its credit facility, which extended the maturity to September 23, 2025. Variable interest rates under the PNMR, PNM, and TNMP revolving credit facilities are based on SOFR.

(10) Pension and Other Postretirement Benefit Plans

PNMR and its subsidiaries maintain qualified defined benefit pension plans, postretirement benefit plans providing medical and dental benefits, and executive retirement programs (collectively, the “PNM Plans” and “TNMP Plans”). PNMR maintains the legal obligation for the benefits owed to participants under these plans. The periodic costs or income of the PNM Plans and TNMP Plans are included in regulated rates to the extent attributable to regulated operations. 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 2022 Annual Reports on Form 10-K. Annual net periodic benefit cost for the plans is actuarially determined using the methods and assumptions set forth in that note and is recognized ratably throughout the year. Differences between TNMP's annual net periodic costs (income) and amounts included in its regulated rates are deferred to regulatory assets or liabilities, for recovery or refund in future rate proceedings.

PNM did not make any contributions to its pension plan trust in the three months ended March 31, 2023 and 2022 and does not anticipate making any contributions to the pension plan in 2023 through 2026 based on current law, funding requirements, and estimates of portfolio performance. In 2027 PNM does anticipate making a contribution of $0.4 million based on current law, funding requirements, and estimates of portfolio performance. Funding assumptions were developed using a discount rate of 5.8%. 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 months ended March 31, 2023 and 2022, 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 $0.8 million and $0.9 million for the three months ended March 31, 2023 and 2022. These payments are expected to total $0.2 million in 2023 and $9.0 million for 2024-2027. Disbursements under the executive retirement program, which are funded by PNM and considered to be contributions to the plan, were $0.1 million and $0.4 million in the three months ended March 31, 2023 and 2022 and are expected to total $1.3 million during 2023 and $4.5 million for 2024-2027.

(11) Commitments and Contingencies

Overview

There are various claims and lawsuits pending against the Company. In addition, the Company is subject to federal, state, and local environmental laws and regulations and periodically participates in the investigation and remediation of various sites. In addition, the Company periodically enters into financial commitments in connection with its business operations. Also, the Company is involved in various legal and regulatory proceedings in the normal course of its business. See Note 12. It is not possible at this time for the Company to determine fully the effect of all litigation and other legal and regulatory proceedings on its financial position, results of operations, or cash flows.

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 estimable. 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 2022 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. In August 2014, APS and the DOE entered into a settlement agreement that established a process for the payment of claims for costs incurred through December 31, 2019. APS has accepted the DOE's extensions of the settlement agreement for recovery of 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 to the extent applicable to NMPRC regulated operations.

PNM estimates that it will incur approximately $59.6 million (in 2019 dollars) for its share of the costs related to the on-site interim storage of spent nuclear fuel at PVNGS during the term of the operating licenses. PNM accrues these costs as a component of fuel expense as the nuclear fuel is consumed. At March 31, 2023 and December 31, 2022, PNM had a liability for interim storage costs of $11.6 million and $12.0 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

New Mexico state law Senate Bill 489, known as the Energy Transition Act (“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. The ETA also directs the New Mexico Environmental Improvement Board to adopt standards of performance that limit CO2 emissions to no more than 1,100 lbs. per MWh beginning January 1, 2023 for new or 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 and will have a significant impact on PNM’s future generation portfolio, including PNM’s retirement of SJGS in 2022 and the planned Four Corners exit in 2024 (subject to regulatory approval). PNM cannot predict the full impact of the ETA or the outcome of its pending and potential future generating resource abandonment and replacement resource filings with the NMPRC. See additional discussion in Note 12 of PNM’s SJGS and Four Corners Abandonment Applications.

The Clean Air Act

Regional Haze

In 1999, EPA developed a regional haze program and regional haze rules under the CAA. The rule directs each of the 50 states to address 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 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. If it was

(Unaudited)

demonstrated that the emissions from these sources caused or contributed to visibility impairment in any Class I area, BART must have been installed by the beginning of 2018. 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. The new rule delayed the due date for the next cycle of SIPs from 2019 to 2021, altered the planning process that states must employ in determining whether to impose “reasonable progress” emission reduction measures, and gave new authority to federal land managers to seek additional emission reduction measures outside of the states’ planning process. Finally, the rule made several procedural changes to the regional haze program, including changes to the schedule and process for states to file 5-year progress reports. EPA’s new rule was challenged by numerous parties. On January 19, 2018, EPA filed a motion to hold the case in abeyance in light of several letters issued by EPA on January 17, 2018 to grant various petitions for reconsideration of the 2017 rule revisions. EPA’s decision to revisit the 2017 rule is not a determination on the merits of the issues raised in the petitions.

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 April 7, 2022, EPA announced its intent to make findings by August 31, 2022 of the states that have failed to submit regional haze implementation plans for the second planning period and directed states to file their plans by August 15, 2022 to avoid inclusion in that finding. Despite that announcement, on April 13, 2022, four environmental groups sued EPA in the U.S. District Court for the Northern District of California seeking to compel EPA to issue a finding that 34 states failed to submit regional haze SIPs for the second planning period. 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 starts a 2-year clock for it to issue a Federal Implementation Plan (FIP). NMED’s current timeline indicates the proposed SIP will be submitted to EPA by October 2023.

Carbon Dioxide Emissions

In 2015, EPA established standards to limit CO2 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 filed petitions for review in the DC Circuit to challenge 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., finding that EPA misinterpreted the CAA when it determined that the language of Section 111 unambiguously barred consideration of emissions reduction options that were not applied at the source. As a result, the court vacated the ACE Rule and remanded the record back to the EPA for further consideration consistent with the court's opinion. While the DC Circuit rejected the ACE Rule, it did not reinstate the Clean Power Plan. EPA filed a motion seeking a partial stay of the mandate as to the repeal of the Clean Power Plan, to ensure the court’s order will not render effective the now out-of-date Clean Power Plan. On February 22, 2021, the U.S. Court of Appeals for the DC Circuit granted EPA’s motion, indicating that it would 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.

On October 29, 2021, the US Supreme Court granted four petitions for writs of certiorari of the D.C. Circuit's decisions, and on June 30, 2022, the US Supreme 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 fenceline at an individual source. Of broader significance in administrative law, the Court expressly invoked the major question doctrine as a basis for rejecting EPA's statutory interpretation. The basic principle of the major question doctrine is that, if an agency seeks to decide an issue of "vast economic or political significance," its action must be supported by clear statutory authorization. In cases where there is no authority, courts need not defer to the agency's statutory interpretation. 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 the Biden Administration is unlikely to finalize the revisions proposed in 2018 and that reconsideration of the rule has concluded.

EPA has commenced the rulemaking process under section 111 to establish new emission guidelines for CO2 emissions from existing power plants. The agency indicates that it plans to publish a draft rule in Spring 2023 and promulgating a final rule by Summer 2024.

On January 27, 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 may occur as a result of legislation or regulation under the Biden Administration and in response to the court's ruling on the ACE Rule is ongoing. PNM cannot predict the impact these standards may have on its operations or a range of the potential costs of compliance, if any.

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, SO2, ozone, and particulate matter.

NOx Standard – In 2018, EPA published the final rule to retain the current primary health-based NOx standards of which NO2 is the constituent of greatest concern and is the indicator for the primary NAAQS. EPA concluded that the current 1-hour and annual primary NO2 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.

SO2 Standard – In 2019, EPA announced its final decision to retain, without changes, the primary health-based NAAQS for SO2. Specifically, EPA will retain the current 1-hour standard for SO2, which is 75 parts per billion, based on the 3-year average of the 99th percentile of daily maximum 1-hour SO2 concentrations.

On March 26, 2021, EPA published in the Federal Register the initial air quality designations for all remaining areas not yet designated under the 2010 SO2 Primary NAAQS. This is EPA’s fourth and final set of actions to designate areas of the U.S. for the 2010 SO2 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. The Center for Biological Diversity filed a lawsuit on February 25, 2021, challenging the decision to retain the existing ozone standard. 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. In April 2022, EPA released an External Review Draft Policy Assessment for the

reconsideration of the ozone NAAQS, in which EPA Staff recommended that EPA retain the existing primary and secondary ozone NAAQS. On March 15, 2023, EPA published an updated draft policy assessment and indicated the revised assessment is being developed for consideration by the EPA Administrator in reaching a decision on the reconsideration of the December 2020 decision to retain the existing ozone NAAQS. The EPA anticipates issuing a proposed decision in this reconsideration in Spring 2024.

In 2015, EPA proposed a rule revising its Exceptional Events Rule, which outlines the requirements for excluding air quality data (including ozone data) from regulatory decisions if the data is affected by events outside an area’s control. The proposed rule is important in light of the more stringent ozone NAAQS final rule since western states like New Mexico and Arizona are subject to elevated background ozone transport from natural local sources, such as wildfires and stratospheric inversions, and transported via winds from distant sources in other regions or countries. EPA finalized the rule on October 3, 2016 and released related guidance in 2018 and 2019 to help implement its new exceptional events policy.

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.

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. In response, NMED published the Public Review Draft of the New Mexico 2013 NAAQS Good Neighbor SIP that demonstrates that there are no significant contributions from New Mexico to downwind problems in meeting the federal ozone standard. On March 15, 2023, EPA Administrator Regan signed a final action indicating that an updated analysis suggests New Mexico may be significantly contributing to one or more nonattainment or maintenance areas. The action, which has not yet been published does not make any final determinations with respect to the state but indicates EPA intends to address New Mexico’s interstate transport obligations in a subsequent action.

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, it is expected to be completed by the end of 2023. PNM cannot predict the outcome of this matter.

PM Standard – On January 30, 2020, EPA published in the Federal Register a notice announcing the availability of a final Policy Assessment for the Review of the NAAQS for Particulate Matter (the "PA"). The 2020 final PA was prepared as part of the review of the primary and secondary PM NAAQS. In the 2020 final PA, EPA recommended lowering the primary annual PM 2.5 standard to between 8 µg/m3 and 10 µg/m3. However, on April 30, 2020, EPA published a proposed rule to retain the current standards for PM due to uncertainties in the data relied upon in the 2020 final PA and EPA published a notice of that final action on December 18, 2020, making it immediately effective. On January 14, 2021, several states and New York City filed a petition for review in the DC Circuit, challenging EPA’s final rule retaining the current primary and secondary PM NAAQS and a similar lawsuit was filed by the Center for Biological Diversity in the DC Circuit. On June 10, 2021, EPA announced that it will reconsider the previous administration’s December 2020 decision to retain the current primary and secondary PM NAAQS and on October 8, 2021, EPA announced the release of a new draft PA stating that available scientific

evidence and technical information indicate that the current standards may not be adequate to protect public health and welfare, as required by the CAA. On June 1, 2022, EPA issued a new final PA that likewise indicates current standards may not be adequate and that available scientific evidence could support lowering the standards.

On January 27, 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. Although the proposal focuses on the range of 9-10 µg/m3, EPA requests comment on a range between 8-11 µg/m3, but that range does not include the current annual standard of 12 µg/m3, indicating EPA will not consider retaining the current standard. Comments on the proposal were due on or before March 28, 2023. EPA’s current regulatory agenda indicates EPA plans to finalize the proposal in August 2023. 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.

EPA has indicated that it is contemplating a December 31, 2023 compliance deadline. With respect to SJGS, no material changes will result given the shutdown of the plant in September of 2022.

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 will spend 12 months sampling discharges from Four Corners and EPA will spend three months completing an analysis. PNM cannot predict whether the analysis to be conducted 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.

On August 3, 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 8, 2023, EPA released the pre-publication version of its proposed ELG Rule. 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 are due 60 days after publication in the Federal Register.

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 that off-site sources have impacted, and are continuing to impact, the local groundwater in the vicinity of the former Santa Fe Generating Station.

PNM submitted work plans to NMED in January 2021 for review and approval. In December 2021, NMED approved both workplans and work activities were completed by the end of 2022 and a report was submitted to the NMED in the first quarter of 2023.

Groundwater sampling for the abatement plan’s first semiannual work commenced at the beginning of March 2023 and was completed in April 2023. The associated report is anticipated to be completed by June 2023. The work plan for the 2023 CAF work is currently under development.

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. EPA intends to issue several other rulemakings covering legacy ponds and finalizing parts of previously proposed rules, including a final rule in August 2023 on remaining Part B issues regarding closure options and annual reporting.

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. Per the Fall 2022 Regulatory Agenda EPA will issue a final rule in August 2023. 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 rule making 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 will need corrective action or will need to cease operations and initiate closure by April 11, 2021. As part of this assessment, Four Corners will continue to gather additional groundwater data and perform remedial evaluations. 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

SJGS

The Coal requirements for SJGS were supplied by WSJ LLC. Pricing under the SJGS CSA was primarily fixed, with adjustments to reflect changes in general inflation. Substantially all of SJGS's coal costs were passed through the FPPAC. See additional discussion of PNM’s SJGS Abandonment Application and summer peak resource adequacy in Note 12. See additional discussion of the SJGS CSA in Note 17 of the Notes to Consolidated Financial Statements in the 2022 Annual Reports on Form 10-K

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. PNM's share of the coal costs is being recovered

through the FPPAC. In connection with the exit of Four Corners, PNM would make payments totaling $75.0 million to NTEC for relief from its obligations under the coal supply agreements for Four Corners after December 31, 2024. PNM is not proposing to recover the $75.0 million from ratepayers and, if approved, would not be recovered through the FPPAC. See Note 12 for additional information on PNM's Four Corners Abandonment Application. See additional discussion of the Four Corners CSA in Note 17 of the Notes to Consolidated Financial Statements in the 2022 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. In 2020, a mine reclamation cost study was completed for the mine that serves SJGS. 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.

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. As discussed in Note 12, PNM remains responsible for its share of costs associated with mine reclamation under the Four Corners Purchase and Sale Agreement with NTEC. Under the agreement NTEC and PNM would complete a reclamation study in 2024 providing the final mine reclamation cost estimate on the date of ownership transfer. PNM will make its final reclamation payment to NTEC based on the reclamation study in 2024 and will have no further obligations regarding the mine reclamation after 2024. PNM determined that events and circumstances regarding Four Corners, including the Four Corners Purchase and Sale Agreement with NTEC and the Four Corners Abandonment Application and subsequent appeal of the NMPRC decision, indicated that it is more likely than not that PNM’s share of Four Corners coal mine reclamation obligation would be settled in 2024, rather than 2031.

Based on the most recent estimates, PNM’s remaining payments as of March 31, 2023 for mine reclamation, in future dollars, are estimated to be $64.5 million for the surface mines at both SJGS and Four Corners and $33.3 million for the underground mine at SJGS. At March 31, 2023 and December 31, 2022, liabilities, in current dollars, of $59.8 million and $62.6 million for surface mine reclamation and $28.4 million and $28.2 million for underground mine reclamation were recorded in other deferred credits.

The SJGS owners entered into a reclamation trust funds agreement to provide funding to compensate WSJ LLC for post-term 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 periodically deposit funds into the reclamation trust for the owner’s share of the mine reclamation obligation. Deposits, which are based on funding curves, must be made on an annual basis. PNM funded $10.0 million in 2022 and, based on PNM’s reclamation trust fund balance at March 31, 2023, the current funding curves indicate PNM’s required contributions to its reclamation trust fund would be zero in each of the years from 2023 through 2025.

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 $2.4 million in 2022, and anticipates providing additional funding of $2.1 million in each of the years from 2023 through 2025. As discussed above, under the terms of the Four Corners Purchase and Sale Agreement with NTEC, PNM will make its final reclamation payment to NTEC based on the reclamation study in 2024 and will have no further obligations regarding the mine reclamation.

PNM recovers from retail customers reclamation costs associated with the underground mine. However, the NMPRC has capped the amount that can be 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. See additional discussion regarding PNM’s SJGS and Four Corners Abandonment Applications in Note 12. PNM is currently unable to determine the outcome of these matters or the range of possible impacts.

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, PNMR entered into the WFB LOC Facility under which letters of credit aggregating $30.3 million have been issued.

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 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 PNM fails 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 2022 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 2022 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. In accordance with this act, the PVNGS participants are insured against public liability exposure for a nuclear incident up to $13.7 billion per occurrence. PVNGS maintains the maximum available nuclear liability insurance in the amount of $450 million, which is provided by American Nuclear Insurers. The remaining $13.2 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. Based on PNM’s current interest in each of the three PVNGS units, PNM's maximum potential retrospective premium assessment per incident for all three units is $31.2 million, with a maximum annual payment limitation of $4.7 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.

Navajo Nation Allottee Matters

In 2012, 43 landowners filed a notice of appeal with the Bureau of Indian Affairs (“BIA”) appealing a March 2011 decision of the BIA Regional Director regarding renewal of a right-of-way for a PNM transmission line. The landowners claim to be allottees, members of the Navajo Nation, who pursuant to the Dawes Act of 1887, were allotted ownership in land carved out of the Navajo Nation and allege that PNM is a rights-of-way grantee with rights-of-way across the allotted lands and are either in trespass or have paid insufficient fees for the grant of rights-of-way or both. The allottees generally allege that they were not paid fair market value for the right-of-way, that they were denied the opportunity to make a showing as to their view

(Unaudited)

of fair market value, and thus denied due process. The allottees filed a motion to dismiss their appeal with prejudice, which was granted in 2014. Subsequent to the dismissal, PNM received a letter from counsel on behalf of what appears to be a subset of the 43 landowner allottees involved in the appeal, notifying PNM that the specified allottees were revoking their consents for renewal of right of way on six specific allotments.

In 2015, PNM received a letter from the BIA Regional Director identifying ten allotments with rights-of-way renewals that were previously contested. The letter indicated that the renewals were not approved by the BIA because the previous consent obtained by PNM was later revoked, prior to BIA approval, by the majority owners of the allotments. It is the BIA Regional Director’s position that PNM must re-obtain consent from these landowners. PNM filed a condemnation action in the NM District Court regarding the approximately 15.49 acres of land at issue. The allottees filed a separate complaint against PNM for federal trespass. On December 1, 2015, the court ruled that PNM could not condemn two of the five allotments at issue based on the Navajo Nation’s fractional interest in the land. PNM filed a motion for reconsideration of this ruling, which was denied. In 2016, the Tenth Circuit granted PNM’s petition to appeal the December 1, 2015 ruling. Both matters have been consolidated. Oral argument before the Tenth Circuit was heard on January 17, 2017. In 2017, the Tenth Circuit affirmed the district court. PNM filed a motion for reconsideration en banc with the Tenth Circuit, which was denied. The NM District Court stayed the case based on the Navajo Nation’s acquisition of interests in two additional allotments and the unresolved ownership of the fifth allotment due to the owner’s death. PNM filed its petition for writ of certiorari with the US Supreme Court, which was denied. The underlying litigation continues in the NM District Court. In 2019, several individual allottees filed a motion for partial summary judgment on the issue of trespass. The Court held a hearing on the motion on June 18, 2019 and took the motion under advisement. In the fourth quarter of 2022, the parties executed a settlement agreement and the court, after a hearing on the matter, entered the stipulated order. The court has retained jurisdiction to ensure compliance with the settlement agreement. Under the settlement agreement, PNM made payments of $1.5 million to the landowners.

Texas Winter Storm

In mid-February 2021, Texas experienced a severe winter storm delivering the coldest temperatures in 100 years for many parts of the state. As a result, the ERCOT market was not able to deliver sufficient generation load to the grid resulting in significant, statewide outages as ERCOT directed transmission operators to curtail thousands of firm load megawatts. TNMP complied with ERCOT directives to curtail the delivery of electricity in its service territory and did not experience significant outages on its system outside of the ERCOT directed curtailments. Various regulatory and governmental entities are conducting, or have announced they may conduct, inquiries, investigations and other reviews of the Texas winter storm event. Entities that have announced that they plan to conduct or are conducting such inquiries, investigations and other reviews include FERC, NERC, Texas Reliability Entity Inc., ERCOT, the Texas Legislature, the Texas Attorney General, the PUCT, and the Galveston County District Attorney. Numerous lawsuits have been filed against various market participants relating to the power outages resulting from the Texas winter storm. TNMP has been named in 22 suits, some not in its service territory, asserting personal injury, wrongful death, and/or property damage. TNMP intends to vigorously defend itself against any claims that might be raised. Additionally, TNMP deferred bad debt expense from defaulting REPs to a regulatory asset which totaled $0.8 million at both March 31, 2023 and December 31, 2022, and will seek recovery in a general rate case. At this time, the Company cannot predict the outcome of such matters or the impact on the ERCOT market.

(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 2022 Annual Reports on Form 10-K.

PNMR

Merger Regulatory Proceedings

On October 20, 2020, PNMR, Avangrid, and Merger Sub entered into the Merger Agreement pursuant to which Merger Sub will merge with and into PNMR, with PNMR surviving the Merger as a wholly-owned subsidiary of Avangrid. Among other conditions, consummation of the Merger is subject to receipt of all required regulatory approvals. In 2021, five federal agencies and the PUCT completed their reviews and approved the Merger, with the NMPRC as the only regulatory agency yet to approve the Merger. The original application before the NMPRC was filed in November 2020. For additional information on the Merger regulatory proceedings, including supplemental regulatory filings that were required due to the Merger Agreement being amended in January 2022 and April 2023, see Note 17.

PNM

New Mexico General Rate Case

2024 Rate Change

On December 5, 2022, PNM filed an application with the NMPRC for a general increase in retail electric rates. The requested change primarily reflects investments in transmission and distribution infrastructure, largely offset by cost reductions resulting from PNM’s transition to lower-cost, clean generation resources. Key aspects of PNM’s request are:

•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

•ROE of 10.25%

•Rate adjustments to resolve revenue deficiencies, including:

◦Needed investments in transmission, distribution, and generation facilities for six years of operations, covering 2019 through 2024. In particular, PNM is focused on expanding and improving its aging infrastructure to provide the underlying infrastructure crucial to a successful energy transition and to support distribution generation.

◦Cost reductions from closing SJGS and the expiration of 114 MW leased PVNGS capacity.

◦Lower-cost replacements for SJGS and PVNGS using renewable energy purchases and battery storage systems. Some of these costs will be reflected in PNM’s requested base rates, while energy purchases will flow through PNM’s FPPAC.

◦Updated depreciation rates, including new terminal dates, for natural gas plants to align with the Company’s 2040 carbon-free portfolio goal.

◦Proposed customer-oriented services, such as fee-free payment options, and increased payment location options to address the needs of customers.

◦Increasing operating costs reflecting six years of inflation, including the impacts of today’s current high inflation and the expenses that come with providing quality electric service to customers. Distribution maintenance increases also are necessary to enhance vegetation management programs to protect lines and support wildfire mitigation efforts. PNM has endeavored to keep operating costs below inflationary levels.

◦Increased energy sales and customer loads since PNM’s last filing help cover the increased cost of doing business as PNM continues the energy transition.

◦Overall cost of capital based on PNM’s actual regulatory capital structure of 52% equity / 48% debt, reflecting the increase in the ROE that shareholders require to fund new investments in PNM’s system, which is partially offset by lower cost of debt.

•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 regarding PVNGS; see PVNGS Lease Abandonment Application below.

•Proposed return of the unamortized unprotected portion of excess deferred federal income taxes to customers over a five-year period, beginning when rates from the case go into effect.

•Time-of-Day pilot proposal with the objective of incentivizing customers, through price signals, to use energy during the day when renewable generation is abundant.

On December 14, 2022, the NMPRC suspended PNM’s advice notice in the case for a period of nine months and appointed hearing examiners. On January 6, 2023, the hearing examiners issued an order setting out a procedural schedule with a hearing to begin June 20, 2023. On February 3, 2023, the hearing examiners issued a recommended decision recommending extension of the statutory suspension period until January 4, 2024, which was adopted by the NMPRC on March 1, 2023. On March 10, 2023, the NMAG and WRA filed a motion for declaratory order with the NMPRC requesting that the NMPRC find that PNM no longer has legal authority to issue ETA bonds because the issuance of the bonds so far from the time of abandonment was not authorized by the Financing Order. On March 27, 2023, PNM filed a motion requesting the NMPRC dismiss or remove issues related to Four Corners regarding prudence for lack of jurisdiction because the matter is on appeal at the NM Supreme Court. On April 7, 2023, the hearing examiners issued an order vacating the remainder of the January 6, 2023 procedural order and set a new procedural schedule with a hearing to begin September 5, 2023.

On January 3, 2023, a joint motion and brief for accounting order was filed with the NMPRC. NM AREA, Staff, WRA, Bernalillo County, NEE, and CCAE (the “Joint Movants”) jointly filed the motion which asked that the NMPRC issue an accounting order for the purpose of requiring PNM to create a regulatory liability to track the costs associated with the

(Unaudited)

retirement of SJGS which are currently embedded in base rates. The Joint Movants requested that the NMPRC order PNM to track all costs associated with the running and management of SJGS totaling $98.3 million annually and requested that the accounting order require PNM to create a regulatory liability to track the SJGS costs from the time Unit 1 and Unit 4 were abandoned, July 1, 2022, and October 1, 2022, respectively, until the date new rates are put into effect, and for any other relief the NMPRC deems is just and reasonable. On February 3, 2023, the hearing examiners issued an order requiring PNM to create a pure accounting order regulatory liability that tracks cost of SJGS which are currently embedded in base rates. On February 6, 2023, PNM filed a motion to permit interlocutory appeal of the hearing examiners order requiring PNM to create a pure accounting order regulatory liability. On February 10, 2023, the hearing examiners issued an order denying PNM’s interlocutory appeal and clarified that the accounting order only required PNM to track the costs of SJGS. On February 14, 2023, NM AREA, Staff, WRA, ABCWUA, and CCAE filed a joint motion for clarification of the hearing examiners accounting order. On April 6, 2023, PNM filed a motion requesting the NMPRC dismiss or remove issues related to the SJGS show cause order for lack of jurisdiction because the matter is on appeal at the NM Supreme Court. For additional discussion on the retirement of SJGS and the associated accounting impacts see SJGS Abandonment Application discussion below. PNM is unable to 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 RCT for the procurement of renewable resources to prevent excessive costs being added to rates. The ETA sets a RCT of $60 per MWh 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 current capacity of 11 MW

•Solar distributed generation, aggregating 250.1 MW at March 31, 2023, 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 2023 renewable energy procurement plan, which became effective on January 1, 2023, PNM proposed to collect $61.0 million for the year. PNM recorded revenues from the rider of $18.6 million and $14.5 million in the three months ended March 31, 2023 and 2022.

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. On March 31, 2023, PNM filed an affidavit that provides documentation that PNM’s ROE for 2022 was 10.173%, exceeding a 10.075% return (9.575% allowed ROE plus 0.5%). PNM will refund the excess to customers effective May 1, 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 not exceed seventy-five thousand dollars.

On April 15, 2020, PNM filed an application for energy efficiency and load management programs to be offered in 2021, 2022, and 2023. The proposed program portfolio consists of twelve programs with a total annual budget of $31.4 million in 2021, $31.0 million in 2022, and $29.6 million in 2023. The application also sought approval of an annual base incentive of 7.1% of the portfolio budget if PNM were to achieve energy savings of at least 80 GWh in a year. The proposed incentive would increase if PNM is able to achieve savings greater than 94 GWh in a year. On October 28, 2020, the NMPRC issued an order approving PNM's proposed efficiency and load management program.

On April 15, 2022, PNM filed an advice notice which reconciles the actual 2021 energy efficiency profit incentive collections with the profit incentive authorized by the NMPRC resulting in an additional $0.3 million incentive to be collected through the energy efficiency rider during the remainder of 2022. The additional incentive was authorized for 2021 because annual energy savings for the year exceeded 94 GWh. PNM began collecting the incentive effective May 31, 2022.

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 proposes 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 10.73%. On April 26, 2023, the NMPRC appointed a hearing examiner. PNM is unable to predict the outcome of this matter.

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 November 24, 2020, the NMAG requested that the NMPRC deny both petitions for declaratory orders and instead address disincentives under the EUEA in a rulemaking. On March 17, 2021, the NMPRC issued an order granting the petitions for declaratory order, commencing a declaratory order proceeding to address the petitions, denying the NMAG’s request to initiate a rulemaking, and appointing a hearing examiner to preside over the declaratory order proceeding.

On January 14, 2022, the hearing examiner issued a recommended decision 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 recommended decision 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 recommended decision 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 recommended decision 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 recommended decision in its entirety. On May 24, 2022, PNM filed a notice of appeal with the NM Supreme Court. On June 23, 2022, PNM and other parties filed Statement of Issues with the NM Supreme Court. On

September 6, 2022, PNM and other parties filed Briefs in Chief with the NM Supreme Court. On October 21, 2022, NEE filed Answer Briefs with the NM Supreme Court. PNM cannot predict the outcome of this matter.

FPPAC Continuation Application

NMPRC rules require public utilities to file an application to continue using their FPPAC every four years. On June 17, 2022, PNM filed the required continuation application and requested that its FPPAC be continued without modification. On July 21, 2022, the NMPRC issued an order requiring Staff to file a response to PNM's application and set certain procedural dates. On August 4, 2022, Staff filed a response to PNM's application stating that while PNM’s filing demonstrates that PNM’s FPPAC meets the requirements of NMPRC rules, it would support a hearing if the NMPRC desires one. On January 27, 2023, the hearing examiner issued a recommended decision recommending that the FPPAC Continuation Application be consolidated into the 2024 Rate Change and on March 1, 2023, the NMPRC issued an order adopting the hearing examiner's recommended decision. The FPPAC Continuation Application is now consolidated into the 2024 Rate Change and the procedural schedule for this matter was vacated.

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 four years of that period. On September 14, 2022, the NMPRC adopted revisions to the IRP Rule. The final order 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 75 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 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 and on January 3, 2023, PNM and 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 jurisdictional 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. PNM cannot predict the outcome of this matter.

2023 IRP

On March 1, 2023, the NMPRC issued an order granting PNM’s Motion for Extension of time to file its 2023 IRP until December 15, 2023, and the deadline for commencing the facilitated stakeholder process was extended until June 15, 2023.

Abandonment Applications made under the ETA

As discussed in Note 11, the ETA provides for a transition from fossil-fueled generating resources to renewable and carbon-free resources by allowing utilities to issue energy transition bonds related to the retirement of certain coal-fired generating facilities, to qualified investors.

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 (the “SJGS Abandonment Application”). The SJGS Abandonment Application sought NMPRC approval to retire PNM’s share of SJGS after the coal supply and participation agreements end in 2022, for approval of replacement resources, and for the issuance of approximately $361 million of energy transition bonds (the “Securitized Bonds”). PNM’s request for the issuance of Securitized Bonds included approximately $283 million of forecasted undepreciated investments in SJGS at June 30, 2022, an estimated $28.6 million for plant decommissioning and coal mine reclamation costs, approximately $9.6 million in upfront financing costs, and approximately $20.0 million for job training and severance costs for affected employees. Proceeds from the Securitized Bonds would also be used to fund approximately $19.8 million for economic development in the Four Corners area. The NMPRC issued an order requiring the SJGS Abandonment Application be considered in two proceedings: one addressing SJGS abandonment and related financing, and the other addressing replacement resources.

In 2020, the NMPRC approved PNM’s proposed abandonment of SJGS, subject to approval of replacement resources, and approved PNM’s proposed financing order to issue Securitized Bonds up to $361 million and establish a rate rider to collect non-bypassable customer charges for repayment of the bonds, subject to bi-annual adjustments (the "Energy Transition Charge"). The NMPRC authorized an interim rate rider adjustment upon the start date of the Energy Transition Charge to provide immediate credits to customers for the full value of PNM’s revenue requirement related to SJGS until those reductions are reflected in base rates. The NMPRC also granted PNM authority to establish regulatory assets to recover costs that PNM will pay prior to the issuance of the Securitized Bonds, including costs associated with the bond issuances as well as for severances, job training, economic development, and workforce training. In addition, the NMPRC authorized PNM to record regulatory assets for certain other abandonment costs that are not specifically addressed under the provisions of the ETA to preserve its ability to recover the costs in a future general rate case, but the authority only extends to the deferral of the costs and is not approval of any ratemaking treatment. Later that year, the NMPRC authorized replacement resource for 650 MW of solar PPAs and 300 MW of battery storage.

On February 28, 2022, WRA and CCAE filed a joint motion for order to show cause and enforce financing order and supporting brief, which requested that the NMPRC order PNM to show cause why its rates should not be reduced at the time SJGS was abandoned. The NMPRC issued an order appointing hearing examiners to conduct a hearing and to issue a recommended decision to address the issues raised by the motion.

On June 17, 2022, the hearing examiners issued a recommended decision requesting the NMPRC issue an order that would require PNM to:

•Revise its rates to remove all of the costs of SJGS Unit 1 by issuing rate credits of $21.1 million on an annual basis, to customers by July 1, 2022

•Revise its rates again, to remove all costs of SJGS Unit 1, Unit 4, and common facilities by increasing the rate credits to $98.3 million on an annual basis, by October 1, 2022

•Transfer payments due and owing to the Indian Affairs Fund, Economic Development Assistance Fund, and the Displaced Workers Assistance Fund within 30 days of the abandonment of SJGS Unit 1

•Include (in its next rate case application) an explanation and defense of the prudence in the timing of the issuance of Securitized Bonds beyond the abandonment dates and what actions were taken to protect customers from interest rate increases occurring as well as the continued marketability of the Securitized Bonds issued

On June 29, 2022, the NMPRC issued its final order adopting and approving the recommended decision in its entirety with certain additions. The additions to the final order include requirements for PNM file a report, no later than October 15, 2022, that contains a record of all of its costs incurred in the show cause proceeding so that the prudence of those costs will be known and be subject to review in PNM's future rate case and that the prudency review shall include a compliance filing to enable a review of the prudence of PNM's decision to delay bond issuance beyond the dates of the SJGS abandonment. On June 29, 2022, PNM filed an Emergency Motion and Supporting Brief for Stay with the NMPRC, which was denied. On June 30, 2022, PNM filed a Notice of Appeal and an Emergency Motion for Partial Interim Stay of the NMPRC's Final Order with the NM Supreme Court. Subsequently, on July 25, 2022, PNM filed another emergency motion seeking an immediate and ongoing stay from the NM Supreme Court for the pendency of the appeal. In the interim, PNM began issuing rate credits effective July 31, 2022, and PNM made payments totaling $19.8 million to the Indian Affairs Fund, Economic Development Assistance Fund, and the Displaced Workers Assistance Fund. On September 2, 2022, the NM Supreme Court issued an order granting PNM's July 25, 2022 motion for partial stay and as a result PNM suspended issuing rate credits. On October 14, 2022,

PNM made its required compliance filing under the NMPRC's June 29, 2022 final order. On November 1, 2022, the NM Supreme Court issued an order continuing the partial stay of the rate credits during the pendency of the appeal. On November 15, 2022, PNM filed a supplemental compliance filing to its October 14, 2022 compliance filing. PNM cannot predict the outcome of this matter.

As required under GAAP, PNM evaluated the consequences of the NMPRC's June 29, 2022 order and the related NM Supreme Court appeal and order granting the stay, as well as the subsequent motions and the hearing examiners' accounting order filed in the 2024 Rate Change. Specifically, PNM assessed the likelihood PNM would be required to establish a regulatory liability for the benefit of the rate credits and the associated carrying charge during the pendency of the stay. These evaluations indicate that it is reasonably possible that PNM would be successful on the issues it was appealing and defending at the NMPRC, and therefore, no loss or regulatory liability has been recorded as of March 31, 2023. The amount of any such loss to be recorded would depend on the ultimate outcome of the appeal, however based on amounts currently included in base rates, discussed above, PNM estimates the potential loss as of March 31, 2023 to be $53.2 million.

Additional information concerning the SJGS Abandonment Application is contained in Note 17 of the Notes to Consolidated Financial Statements in the 2022 Annual Reports on Form 10-K.

Four Corners Abandonment Application

On November 1, 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. The sale is contingent upon NMPRC approval and is expected to close by the end of 2024. 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. Pursuant to the Four Corners Purchase and Sale Agreement, PNM would retain its current plant decommissioning and coal mine reclamation obligations. 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 is 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. PNM’s request for the issuance of Securitized Bonds included approximately $272 million of forecasted undepreciated investments in Four Corners at December 31, 2024, an estimated $4.6 million for plant decommissioning costs, an estimated $7.3 million in upfront financing costs, and an estimated $16.5 million for economic development in the Four Corners area.

On March 15, 2021, PNM filed an amended application and supplemental testimony for the approval of the abandonment and transfer of Four Corners and issuance of a financing order pursuant to the ETA and a motion to withdraw the January 8, 2021 Four Corners Application. The amended application and supplemental testimony provided additional information to support PNM's request to abandon its interest in Four Corners and transfer that interest to NTEC, and also provided additional detail explaining how the proposed sale and abandonment provides a net public benefit.

On November 12, 2021, the hearing examiner issued a recommended decision recommending approval of the Four Corners Abandonment Application and the corresponding request for issuance of securitized financing. On December 15, 2021, the NMPRC issued a final order rejecting the hearing examiner's recommended decision and denying approval of the Four Corners Abandonment Application and the corresponding request for issuance of securitized financing. In its order, the NMPRC concluded that PNM needed to conduct a review of the actual replacement resource portfolio and determined that the record was insufficient to determine the prudence of PNM’s investments in Four Corners. On December 22, 2021, PNM filed a Notice of Appeal with the NM Supreme Court of the NMPRC decision to deny the application. On January 21, 2022, PNM filed its Statement of Issues outlining the arguments for appeal asserting, among other things, that the NMPRC misinterpreted and improperly applied the ETA in concluding that the NMPRC needed to review the actual replacement resource portfolio before authorizing abandonment and that the NMPRC improperly deferred the issue of prudence with respect to certain of PNM’s investments in Four Corners, where other parties were given the opportunity to present evidence and failed to demonstrate PNM was imprudent in its decisions. On March 24, 2022, PNM filed its Brief in Chief and answer briefs were filed on May 9, 2022. On June 17, 2022, PNM filed its Consolidated Reply Brief and on March 28, 2023, the NM Supreme Court heard oral arguments on the appeal.

GAAP requires a loss be recognized when it is probable that a loss has been incurred and the amount of loss can be reasonably estimated. As of March 31, 2023, PNM evaluated the NMPRC order in the Four Corners Abandonment Application and determined it was reasonably possible that PNM would be successful in recovery of its undepreciated investment in a future proceeding. Therefore, no loss has been recorded.

The financial impact of an early exit of Four Corners and the NMPRC approval process is influenced by many factors outside of PNM’s control, including the overall political and economic conditions of New Mexico. See additional discussion of the ETA in Note 11. PNM cannot predict the outcome of these matters.

PVNGS Leased Interest Abandonment Application

On April 2, 2021, PNM filed the PVNGS Leased Interest Abandonment Application, an application for the sale and transfer of related assets, and approval to procure new resources. As discussed in Note 13, PNM had Leased Interest under five separate leases that were approved and certificated by the predecessor agency to the NMPRC in the 1980s. Four of the five leases for 104 MW of Leased Interest terminated in January 2023, while the remaining lease for 10 MW of Leased Interest terminates in January 2024. Associated with the Leased Interest are certain PNM-owned assets and nuclear fuel that are necessary for the ongoing operation and maintenance of the Leased Interest and integration of the Leased Interest generation to the transmission network. PNM determined that there will be net benefits to its customers to return the Leased Interest to the lessors in conformity with the leases, sell and transfer the related PNM-owned assets, and to replace the Leased Interest with new resources. In the application, PNM requested NMPRC authorization to decertify and abandon its Leased Interest and to create regulatory assets for the associated remaining undepreciated investments with consideration of cost recovery of the undepreciated investments in a future rate case. PNM also sought NMPRC approval to sell and transfer the PNM-owned assets and nuclear fuel supply associated with the Leased Interest to SRP, which has and will acquire the Leased Interest from the lessors upon termination of the existing leases. In addition, PNM sought NMPRC approval for a 150 MW solar PPA combined with a 40 MW battery storage agreement, and a stand-alone 100 MW battery storage agreement to replace the Leased Interest. To ensure system reliability and load needs are met in 2023, when a majority of the leases expire, PNM also requested NMPRC approval for a 300 MW solar PPA combined with a 150 MW battery storage agreement. PNM's application sought a six-month regulatory time frame.

On April 21, 2021, the NMPRC issued an order assigning a hearing examiner and stated PNM's request to abandon the Leased Interest does not have any statutory or rule time limitation and the six-month limit in which the NMPRC must issue an order regarding the request for approvals of the solar PPAs and battery storage agreements does not begin until after the NMPRC acts on the abandonment request. The NMPRC's April 21, 2021 order also stated that issues reserved to a separate proceeding in the NM 2015 Rate Case regarding the decision to permanently disallow recovery of certain future decommissioning costs related to PVNGS Units 1 and 2 shall be addressed in this case and PNM shall file testimony addressing the issue. On June 28, 2021, NEE and CCAE jointly filed a motion to dismiss a portion of the application claiming that since PNM's request to abandon the Leased Interest was filed after PNM had already provided irrevocable notice it would not acquire the Leased Interest, abandonment is no longer required. On July 28, 2021, the hearing examiner issued a recommended decision on NEE's and CCAE's joint motion to dismiss, recommending dismissal of PNM's requests for approval to abandon and decertify the Leased Interest; dismissal of PNM's request for approval to sell and transfer the related assets; and dismissal of PNM's request to create regulatory assets for the associated remaining undepreciated investments, but did not preclude PNM seeking recovery of the costs in a general rate case in which the test year period includes the time period in which PNM incurs such costs. The hearing examiner's recommended decision further provides that PNM's request for replacement and system reliability resources and the decision to permanently disallow recovery of certain future decommissioning costs related to PVNGS Units 1 and 2 should remain within the scope of this case.

On August 25, 2021, the NMPRC issued an order granting portions of the July 28, 2021 recommended decision that were not contested related to dismissal of PNM's request for approval to abandon and decertify the Leased Interest and dismissal of PNM's request for approval to sell and transfer the related assets. In addition, the order bifurcated the issue of approval for the two PPAs and three battery storage agreements into a separate docket so it may proceed expeditiously. On September 8, 2021, the NMPRC issued an order on the remaining issues in the recommended decision. The order found that PNM's request for a regulatory asset to record costs associated with obtaining an abandonment order should be dismissed. However, the requests for regulatory assets associated with the remaining undepreciated investments should be addressed at an evidentiary hearing. On September 20, 2021, ABCWUA, Bernalillo County, NEE, and the NMAG filed a joint motion to reconsider the September 8, 2021 NMPRC order. Also, on September 20, 2021, PNM filed a motion for rehearing of the September 8, 2021 order stating that certain requirements of the order would lead to compromising PNM's First Amendment

rights. On October 6, 2021, the NMPRC issued an order granting the motions for reconsideration and vacated the September 8, 2021 order, without specifically addressing issues raised in the motions.

On November 1, 2022, ABCWUA, Bernalillo County, CCAE, NEE, NM AREA, the NMAG, WRA, and Staff filed a joint motion for an accounting order to require PNM to track in a regulatory liability, all costs associated with the PVNGS Leased Interests that will be abandoned in January 2023 and January 2024 that are still being collected in rates, which PNM opposed. On November 18, 2022, the NMPRC issued its order on joint motion for an accounting order requiring PNM to establish a regulatory liability to track and account for, upon termination of the PVNGS leases, all costs currently borne by ratepayers associated with those leases during pendency of the 2024 Rate Change, subject to a determination of ratemaking treatment. In addition, PNM may establish a regulatory asset account to record undepreciated investment for improvements to the Unit 1 and Unit 2 Leased Interests upon termination of the leases, and to record cost differences in the proceeds from SRP for the sale of the PVNGS Leased Assets and the actual book value. Recovery of these items will be determined in the 2024 Rate Change. In the 2024 Rate Change, PNM must also address unresolved issues including whether PNM’s decision to renew the five leases and repurchase 64.1 MW of PVNGS Unit 2 capacity exposed ratepayers to additional financial liability beyond that to which they would otherwise have been exposed, and whether PNM should be denied recovery of future decommissioning expenses as a remedy for imprudence. See 2024 Rate Change discussion above.

PNM evaluated the consequences of the NMPRC's November 18, 2022 accounting order, as required under GAAP, and whether it should establish a regulatory liability in 2023 to account for revenue collected from ratepayers during the pendency of the 2024 Rate Change. In addition, PNM evaluated whether it should establish a regulatory asset account to record undepreciated investment for improvements to the Unit 1 and Unit 2 Leased Interests upon termination of the leases in January 2023 and 2024. Based on these evaluations PNM concluded that the accounting order was not tied to a specific rate order and does not change PNM's resources or obligations and those decisions will be determined in the 2024 Rate Change. Therefore, no loss or regulatory liability has been recorded as of March 31, 2023. The amount of any such loss to be recorded would depend on the ultimate outcome of the 2024 Rate Change, however based on amounts currently included in base rates, PNM estimates the potential loss as of March 31, 2023 to be $8.7 million. PNM does not consider a disallowance of all or part of the cost of the undepreciated leasehold improvements to be probable and reasonably estimable at this time, and in the first quarter of 2023 reclassified $88.2 million of undepreciated leasehold improvements, previously reflected in Net utility plant, to a deferred regulatory asset on PNMR's and PNM's Condensed Consolidated Balance Sheet at March 31, 2023.

The hearing on the two PPAs and three battery storage agreements was held on November 12 and 15, 2021 and December 3, 2021. On February 14, 2022, the hearing examiner issued a recommended decision recommending the NMPRC approve the 150 MW solar PPA combined with a 40 MW battery storage agreement, the stand-alone 100 MW battery storage agreement, and the 300 MW solar PPA combined with a 150 MW battery storage agreement. On February 16, 2022, the NMPRC adopted an order approving the recommended decision. On April 15, 2022, PNM made a compliance filing with the NMPRC in which it updated the NMPRC on the status of the PPAs and the battery storage agreements listed above. On June 16, 2022, PNM made a second compliance filing on the status of PPAs and battery storage agreements notifying the NMPRC that none of the developers of the two PPAs and three battery storage agreements have moved forward under the terms of the agreements approved by the NMPRC on February 16, 2022, and none of the replacement resource projects would be operational in 2023. All five projects will have significant delays and price increases as evidenced in the current alternative offers from the developers. PNM entered into amendments to the 300 MW solar PPA combined with a 150 MW battery storage agreement and proposed those amendments to the NMPRC for approval in a filing with the NMPRC on June 24, 2022. PNM determined the terms offered by the 150 MW solar PPA combined with a 40 MW battery storage agreement and the stand-alone 100 MW battery storage agreement are not satisfactory in comparison with other potential projects that might be utilized instead, and PNM did not support the proposed amendments to those agreements in the June 24, 2022 filing. No party filed objections following PNM's June 24, 2022 filing and pursuant to the NMPRC's February 16, 2022 order the 300 MW solar PPA combined with 150 MW battery storage agreement and the decision not to proceed with the other agreements, are deemed approved. On September 2, 2022, PNM entered into amendments to the 150 MW battery storage agreement to increase the capacity to 300 MW and proposed those amendments to the NMPRC for approval. On September 8, 2022, the NMPRC issued an order to extend the 10-day period for filing for an additional two days. No party filed objections within 12 days following PNM's September 2, 2022 filing and pursuant to the NMPRC's February 16, 2022 order the 300 MW solar battery storage agreement was deemed approved. PNM anticipates these facilities will be in service in 2024.

In addition to approval by the NMPRC, PNM and SRP received NRC approval for the transfer of the associated possessory licenses at the end of the term of each of the respective leases.

Summer Peak Resource Adequacy

Throughout 2021, 2022 and continuing into 2023, PNM provided notices of delays and status updates to the NMPRC for the approved SJGS replacement resource projects. All four project developers had notified PNM that completion of the projects would be delayed and no longer available for most, if any of the 2022 summer peak load period. While PNM experienced a new system peak retail load of 2,139 MW on July 19, 2022, PNM’s generation resources performed sufficiently with no significant challenges to resource adequacy during the 2022 summer peak season.

PNM faces similar concerns in the summer of 2023 as a result of continued delays in the SJGS replacement resources as well as delays in replacement resources for the PVNGS leased capacity that expired in January 2023. As discussed above, PNM has made a number of compliance filings with the NMPRC on the status of the SJGS and PVNGS leased capacity interest replacement resources. On January 30, 2023, PNM informed the NMPRC that it had provided written notice to one of the SJGS replacement resource developers for 100 MW solar PPA and a 30 MW battery storage agreement of an event of seller default and of early termination and as a result the project would not proceed. In the second half of 2022 and the first quarter of 2023, PNM entered into agreements totaling 420 MW of firm power purchases for the summer peak in 2023 and the purchase of 40 MW of firm capacity at PVNGS for all twelve months of 2023, providing PNM with a projected system reserve margin with a range of approximately 11.0% to 16.0% for the 2023 summer peak period. PNM continues to evaluate other potential firm power agreements with various providers, as well as all potential short-term resource options to address these resource adequacy concerns. PNM is unable to predict the outcome of this matter.

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. PNM's application requested NMPRC approval by July 1, 2023 for PNM's grid modernization plan in addition to approval of PNM's proposed Grid Modernization Rider by September 1, 2023. 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 methodology to determine PNM’s proposed cost-based opt-out fees, which includes a one-time fee and a monthly fee. A hearing was held on March 20, 2023 through March 24, 2023. Post-hearing briefs were filed April 20, 2023, with response briefs due May 10, 2023. PNM is unable to predict the outcome of this matter.

COVID-19 Regulatory Matters

In 2020, the NMPRC issued an order authorizing all public utilities regulated by the NMPRC to create a regulatory asset to defer incremental costs related to COVID-19, including increases to bad debt expense incurred during the period beginning March 11, 2020 through the termination of the Governor of New Mexico’s emergency executive order. The NMPRC order requires public utilities creating regulatory assets to pursue all federal, state, or other subsidies available, to record a regulatory liability for all offsetting cost savings resulting from the COVID-19 pandemic, and allows PNM to request recovery in future ratemaking proceedings. As a result, PNM has deferred costs related to COVID-19 of $5.7 million in regulatory assets on the Condensed Consolidated Balance Sheet at both March 31, 2023 and December 31, 2022. Although PNM is seeking recovery for the increase in bad debt expense resulting from COVID-19 through a regulatory asset in the 2024 Rate Change, it no longer intends to seek recovery of other incremental costs related to the pandemic. In addition, PNM has cost savings related to COVID-19 of $0.9 million in regulatory liabilities on the Condensed Consolidated Balance Sheets at both March 31, 2023 and December 31, 2022.

The Community Solar Act

In June 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 accessing solar energy produced by a community solar facility in accordance with the Community Solar Act. The NMPRC is charged with administering the Community Solar Act program, establishing a total maximum capacity of 200 MW community solar (applicable until November 2024) facilities and allocating proportionally to the New Mexico electric investor-owned utilities and participating cooperatives. As required under the Community Solar Act, the NMPRC opened a docket on May 12, 2021 to adopt rules to establish a community solar program no later than April 1, 2022. On June 15, 2021, the NMPRC issued an order which required utilities provide a notice to all future applicants and to any likely applicants that, until the effective date of the NMPRC's rules in this area the NMPRC's existing interconnection rules and manual remain in place until amended or replaced by the NMPRC, and further, that a place in a utility's applicant queue for interconnection does not and will not provide any advantage for selection as a community solar project. PNM has provided the required notices. On October 27, 2021, the NMPRC adopted an order issuing a NOPR starting the formal process for adoption of rules pursuant to the Community Solar Act. On March 30, 2022, the NMPRC issued an order that adopted a rule on the administration of the Community Solar Act program. The rule requires utilities to file proposed community solar tariffs with the NMPRC within 60 days from the publication of the rule. A number of motions for rehearing and requests for clarification were filed between April 7 and May 2, 2022. On May 18, 2022, the NMPRC issued an order partially granting motions for rehearing, reconsideration and clarification and staying implementation pending further rulemaking. On June 16, 2022, PNM requested clarification related to the existing interconnection queue, which would not delay implementation of the Community Solar Act program. On July 12, 2022, the NMPRC provided notice of publication of its final rule in the New Mexico Register, starting the 60-day clock for utilities to file their proposed community solar tariffs, forms, and other relevant agreements. On September 14, 2022, PNM filed Community Solar tariffs. On October 12, 2022, the NMPRC issued an order to suspend PNM's and two other investor-owned utilities tariffs and required the utilities to file information Staff has identified as necessary for a complete evaluation of the tariffs but did not appoint a hearing examiner or schedule a public hearing. Another investor-owned utility has filed an appeal with the NM Supreme Court seeking review of the NMPRC’s decisions. On November 16, 2022, PNM filed its Community Solar tariff which establishes the Community Solar bill credit to be applied to an eligible retail customer of PNM who is a subscriber to a community solar facility. On December 23, 2022, PNM filed an updated Community Solar tariff under protest and filed a motion for clarification, suspension, and timely hearing on PNM’s Community Solar tariff. On January 18, 2023, the NMPRC suspended PNM’s Community Solar tariff. On March 1, 2023, the NMPRC issued an Order Opening a New Docket for Two-Phase Proceedings. The first phase will address issues concerning the proposed subscriber organization agreements and the proposed customer data forms. The second phase will address all issues concerning proposed tariffs, agreements and forms that are not addressed in the first phase. PNM cannot predict the outcome of the pending matters.

Battery Energy Storage System Certificate of Public Convenience and Necessity ("CCN")

On May 3, 2023, PNM filed a CCN application with the NMPRC for two battery energy storage systems, 6 MW each, located on PNM's distribution system in Valencia and Bernalillo counties. PNM intends to construct, own, and operate these systems that will be interconnected to the distribution system on feeders that currently exceed their existing hosting capacity limits due to the high amount of solar production connected to them. The deployment of battery energy storage systems on these feeders at capacity will bring the power flow on the feeders back within design limits, potentially allowing a number of solar interconnection applications currently on hold to interconnect, which will in turn reduce carbon emissions and the need to curtail solar production in times of oversupply. PNM is requesting approval of the CCN application, with an estimated total cost of $25.8 million, by December 31, 2023 to support the proposed construction schedule and have the battery energy storage systems begin serving customers in June 2024.

FERC Order 864

In November 2019, FERC issued Order No. 864, which required public utility transmission providers with transmission formula rates to revise those rates to account for changes resulting from the Tax Cuts and Jobs Act of 2017 (the “Tax Act”). PNM had already made revisions to its formula rate to account for Tax Act changes, and, as a result of the Order, PNM proposed additional changes to its formula rate to implement the remaining requirements of the Order. In July 2022, FERC issued an order finding that PNM had predominantly complied with the requirements but set aside certain matters for settlement and hearing procedures. PNM is unable to determine the outcome of this matter.

TNMP

Transmission Cost of Service Rates

TNMP can update its transmission cost of service ("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)














September 20, 2021	$41.2	$6.3
March 25, 2022	$95.6	$14.2
September 22, 2022	$36.0	$5.3

On January 23, 2023, TNMP filed an application to further update its transmission rates, which would increase revenues by $19.4 million annually, based on an increase in rate base of $150.5 million. The application is pending before the PUCT.

Periodic Distribution Rate Adjustment

PUCT rules permit interim rate adjustments to reflect changes in investments in distribution assets. Distribution utilities may file for a periodic rate adjustment between April 1 and April 8 of each year as long as the electric utility is not earning more than its authorized rate of return using weather-normalized data. Utilities are limited to four periodic interim distribution rate adjustments between general rate cases. 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, 2021	$104.5	$13.5
September 1, 2022	$95.7	$6.8

On April 5, 2023, TNMP filed its 2023 DCRF that requested an increase in TNMP annual distribution revenue requirement of $14.8 million based on an increase in rate base of $157.0 million. The case is pending review by the PUCT.

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 2021 EECRF filing requested recovery of $7.2 million, including a performance bonus of $2.3 million, and became effective March 1, 2022. On May 27, 2022, TNMP filed its request to adjust the EECRF to reflect changes in costs for 2023. The total amount requested was $7.4 million, which includes a performance bonus of $1.9 million based on TNMP's energy efficiency achievements in the 2021 plan year. On August 24, 2022, a unanimous stipulation and settlement was filed with the PUCT to recover $7.3 million in 2023, including the performance bonus of $1.9 million. On October 6, 2022, the PUCT approved the unanimous stipulation.

(13) Lease Commitments

The Company leases office buildings, vehicles, and other equipment. In addition, PNM leases interests in PVNGS Units 1 and 2 and 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 2022 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 expires in January 2024. The annual lease payments during the renewal periods aggregate $1.6 million on the remaining PVNGS Unit 2 lease.

The terms of each of the extended leases do not provide for additional renewal options beyond their currently scheduled expiration dates. PNM had the option to purchase the assets underlying each of the extended leases at their fair market value or to return the lease interests to the lessors on the expiration dates. On June 11, 2020, PNM provided notice to the lessors and the NMPRC of its intent to return the assets underlying both the PVNGS Unit 1 and Unit 2 leases upon their expiration in January 2023 and 2024. Although PNM elected to return the assets underlying the extended leases, PNM retains certain obligations related to PVNGS, including costs to decommission the facility. PNM depreciates its capital improvements related to the extended leases using NMPRC approved rates through the end of the NRC license period for each unit, which expire in June 2045 for Unit 1 and in June 2046 for Unit 2. Upon expiration of the leases PNM will cease depreciation and as authorized by the NMPRC create a regulatory asset for the associated remaining undepreciated investments.

On April 5, 2021, PNM and SRP entered into an Asset Purchase and Sale Agreement, pursuant to which PNM agreed to sell to SRP certain PNM-owned assets and nuclear fuel necessary to the ongoing operation and maintenance of leased capacity in PVNGS Unit 1 and Unit 2, which SRP has agreed to acquire from the lessors upon termination of the existing leases. The proposed transaction between PNM and SRP received all necessary approvals, including NRC approval for the transfer of the associated possessory licenses to SRP at the end of the term of each of the respective leases. In January 2023, the Unit 1 leases expired, and PNM closed on the associated sale to SRP, 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. See Note 12 for information on other PVNGS matters including the PVNGS Leased Interest Abandonment Application which included PNM's request to create regulatory assets for the associated remaining undepreciated investments.

PNM is exposed to loss under the PVNGS lease arrangements upon the occurrence of certain events that PNM does not consider reasonably likely to occur. Under certain circumstances (for example, the NRC issuing specified violation orders with respect to PVNGS or the occurrence of specified nuclear events), PNM would be required to make specified payments to the lessors and take title to the leased interests. If such an event had occurred as of March 31, 2023, amounts due to the lessors under the circumstances described above would be up to $13.8 million, payable on July 15, 2023 in addition to the scheduled lease payments due on that date.

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 2023 payment for the amount due under the Navajo Nation right-of-way lease was $8.3 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 March 31, 2023 and December 31, 2022, the unamortized balance of

these rights-of-ways was $58.3 million and $54.6 million. PNM recognized amortization expense associated with these agreements of $0.9 million and $1.0 million in the three months ended March 31, 2023 and 2022.

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 March 31, 2023, residual value guarantees on fleet vehicle and equipment leases are $1.0 million, $1.2 million, and $2.1 million for PNM, TNMP, and PNMR Consolidated.

The above table includes $12.3 million, $12.8 million, and $25.1 million for PNM, TNMP, and PNMR at March 31, 2023 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 March 31, 2023, 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 2023 and 2024, with lease terms expiring in 2044, 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 $1.3 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, including excess tax benefits or tax deficiencies related to stock awards and taxes on Merger-related costs are excluded from the estimated annual effective tax

(Unaudited)

rate calculation. At March 31, 2023, PNMR, PNM, and TNMP estimated their effective income tax rates for the year ended December 31, 2023 would be 15.38%, 18.03%, and 14.14%. 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 three months ended March 31, 2023, income tax expense calculated by applying the expected annual effective income tax rate to earnings before income taxes was further reduced by excess tax benefits related to stock awards of $0.2 million for PNMR, of which $0.2 million was allocated to PNM and less than $0.1 million was allocated to TNMP.

Beginning February 2018, PNM’s NM 2016 Rate Case reflects 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 the unprotected portion of excess deferred federal income taxes to customers over a period of approximately twenty-three years. 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. PNMR, PNM, and TNMP will amortize federal excess deferred income taxes of $22.9 million, $14.3 million, and $8.6 million in 2023. See additional discussion of PNM’s NM 2016 Rate Case and TNMP’s 2018 Rate Case in Note 17 of the Notes to Consolidated Financial Statements in the 2022 Annual Reports on Form 10-K. See additional discussion of the impacts of the Tax Act in Note 18 of the Notes to Consolidated Financial Statements in the 2022 Annual Reports on Form 10-K.

(15) Related Party Transactions

PNMR, PNM, TNMP, and NMRD are considered related parties, as is PNMR Services Company, a wholly-owned subsidiary of PNMR that provides corporate services to PNMR 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, PNMR provides construction and operations and maintenance services to NMRD, a 50% owned subsidiary of PNMR Development. PNM purchases renewable energy from certain NMRD-owned facilities at a fixed price per MWh of energy produced. PNM also provides interconnection services to PNMR Development and NMRD.

(16) Equity Method Investment

As discussed in Note 21 of the Company's 2022 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. As of March 31, 2023, NMRD’s renewable energy capacity in operation was 135.1 MW. PNMR Development and AEP OnSite Partners each have a 50% ownership interest in NMRD. The investment in NMRD is accounted for using the equity method of accounting because PNMR’s ownership interest results in significant influence, but not control, over NMRD and its operations.

In the three months ended March 31, 2023, PNMR Development and AEP OnSite Partners each made cash contributions to NMRD of $11.5 million for its construction activities. In the three months ended March 31, 2022, neither PNMR Development nor AEP OnSite Partners made any cash contributions to NMRD for its construction activities.

PNMR presents its share of net earnings from NMRD in other income on the Condensed Consolidated Statements of Earnings. Summarized financial information for NMRD is as follows:

(17) Merger

The proposed Merger has been unanimously approved by the Boards of Directors of PNMR, Avangrid and Merger Sub and approved by PNMR shareholders at the Special Meeting of Shareholders held on February 12, 2021.

The Merger Agreement provided that it may be terminated by each of PNMR and Avangrid under certain circumstances, including if the Effective Time shall not have occurred by the January 20, 2022 End Date; however, either PNMR or Avangrid could extend the End Date to April 20, 2022 if all conditions to closing have been satisfied other than the obtaining of all required regulatory approvals. As discussed below, in December 2021, the NMPRC issued an order rejecting the stipulation agreement relating to the Merger. In January 2022, PNMR, Avangrid and Merger Sub entered into an Amendment to the Merger Agreement pursuant to which PNMR and Avangrid agreed to extend the End Date to April 20, 2023.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

On April 12, 2023, PNMR, Avangrid, and Merger Sub entered into Amendment No. 2 to the Merger Agreement whereby all of the parties agreed to extend the End Date to July 20, 2023.

The Merger is subject to certain regulatory approvals, including from the NMPRC. The Joint Applicants to the NMPRC application and a number of intervening parties had entered into an amended stipulation and agreement in the Joint Application for approval of Merger pending before the NMPRC. An evidentiary hearing was held in August 2021. On November 1, 2021, a Certification of Stipulation was issued by the hearing examiner, which recommended against approval of the amended stipulation. On December 8, 2021, the NMPRC issued an order adopting the Certification of Stipulation, rejecting the amended stipulation reached by the parties. On January 3, 2022, PNMR and Avangrid filed a notice of appeal with the NM Supreme Court. On February 2, 2022, PNMR and Avangrid filed a statement of issues outlining the argument for appeal. On April 7, 2022, PNMR and Avangrid filed their Brief in Chief with the NM Supreme Court. Answer briefs from the NMPRC were filed on June 14, 2022, and response briefs were filed on August 5, 2022. On March 8, 2023, PNM, Avangrid, and the NMPRC filed a motion with the NM Supreme Court to dismiss the appeal and remand the proceeding back to the NMPRC for further proceedings. The motion states that, once granted, PNM and Avangrid intend to file a motion for rehearing and/or reconsideration at the NMPRC. One party opposed the motion and certain other parties have sought clarification regarding the process that the NMPRC would implement on remand.

With respect to other regulatory proceedings related to the Merger, in 2021 PNMR received clearances for the Merger from the FTC under the HSR Act, CFIUS, the FCC, FERC, the PUCT, and the NRC. As a result of the delay in closing of the Merger due to the need to obtain NMPRC approval, PNMR and Avangrid were required to make a new filing under the HSR Act and request extensions of approvals previously received from the FCC and NRC. PNM has received approval from the FCC that runs through September 5, 2023, approval from the NRC that runs through May 25, 2024 and clearance under the HSR Act through March 10, 2024. No additional approvals are required from CFIUS, FERC or the PUCT.

Consummation of the Merger remains subject to the satisfaction or waiver of certain customary closing conditions, including, without limitation, the absence of any material adverse effect on PNMR, the receipt of required regulatory approval from the NMPRC, and the agreements relating to the divestiture of Four Corners being in full force and effect and all applicable regulatory filings associated therewith being made. The agreement relating to the divestiture of Four Corners has been entered into and is in full effect and related filings have been made with the NMPRC.

The Merger Agreement provides for certain customary termination rights. The Merger Agreement further provides that, upon termination of the Merger Agreement under certain specified circumstances (including if Avangrid terminates the Merger Agreement due to a change in recommendation of the Board or if PNMR terminates the Merger Agreement to accept a superior proposal (as defined in the Merger Agreement) and in either case prior to PNMR's shareholder having approved the Merger), PNMR will be required to pay Avangrid a termination fee of $130.0 million. In addition, the Merger Agreement provides that (i) if the Merger Agreement is terminated by either party due to a failure of a regulatory closing condition and such failure is the result of Avangrid’s breach of its regulatory covenants or (ii) Avangrid fails to effect the closing when all closing conditions have been satisfied and it is otherwise obligated to do so under the Merger Agreement, then, in either such case, upon termination of the Merger Agreement, Avangrid will be required to pay PNMR a termination fee of $184.0 million as the sole and exclusive remedy. Upon the termination of the Merger Agreement under certain specified circumstances involving a breach of the Merger Agreement, either PNMR or Avangrid will be required to reimburse the other party’s reasonable and documented out-of-pocket fees and expenses up to $10.0 million (which amount will be credited toward, and offset against, the payment of any applicable termination fee).

MD&A FOR PNMR

EXECUTIVE SUMMARY

Overview and Strategy

PNMR is a holding company with two regulated utilities serving approximately 817,000 residential, commercial, and industrial customers and end-users of electricity in New Mexico and Texas. PNMR’s electric utilities are PNM and TNMP. PNMR strives to create a clean and bright energy future for customers, communities, and shareholders. PNMR’s strategy and decision-making are focused on safely providing reliable, affordable, and environmentally responsible power built on a foundation of Environmental, Social and Governance (ESG) principles.

Recent Developments

Merger

On October 20, 2020, PNMR, Avangrid and Merger Sub entered into the Merger Agreement pursuant to which Merger Sub will merge with and into PNMR, with PNMR surviving the Merger as a wholly-owned subsidiary of Avangrid. Pursuant to the Merger Agreement, each issued and outstanding share of PNMR common stock at the Effective Time will be converted into the right to receive $50.30 in cash. The proposed Merger has been unanimously approved by the Boards of Directors of PNMR, Avangrid and Merger Sub and approved by PNMR shareholders at the Special Meeting of Shareholders held on February 12, 2021.

The Merger Agreement provided that it may be terminated by each of PNMR and Avangrid under certain circumstances, including if the Effective Time shall not have occurred by the January 20, 2022 End Date. On December 8, 2021, the NMPRC issued an order rejecting the stipulation agreement relating to the Merger. In light of the NMPRC ruling, on January 3, 2022, PNMR, Avangrid and Merger Sub entered into an Amendment to the Merger Agreement pursuant to which PNMR and Avangrid agreed to extend the End Date to April 20, 2023. On April 12, 2023, PNMR, Avangrid, and Merger Sub agreed to further extend the End Date to July 20, 2023. The Merger is subject to certain regulatory approvals, including from the NMPRC. For further discussion regarding the Merger, see Note 17.

Retirement of SJGS

After nearly half a century of reliable service and several years of planning towards its retirement, the last unit of the coal-fired SJGS has been removed from service, as PNM achieves significant progress towards its ESG goals for reducing carbon emissions from its generation portfolio. The four-unit, coal-fired SJGS, whose first unit was brought online in 1973, was reduced to two units at the end of 2017 with the retirement of Units 2 and 3. Unit 1 was retired in June 2022, and Unit 4 was retired in September 2022. Coal-fired generation now comprises less than 10% of resource portfolio capacity for PNM. Carbon-free generation comprises 55% of the Company’s 2.7-gigawatt capacity serving New Mexico customers, with additional renewable resources under development for implementation in the coming years. The Company previously published emissions goals for 2025 including a 60% reduction of carbon emissions from owned generation facilities based on 2005 levels. The retirement of SJGS achieves this interim goal and places the Company in position to reach its industry-leading goal of completely eliminating carbon emissions from its generation portfolio by 2040.

2024 Rate Change

In December 2022, PNM filed the 2024 Rate Change with the NMPRC. The application proposes 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%. The requested change primarily reflects investments in transmission and distribution infrastructure, largely offset by cost reductions resulting from PNM’s transition to lower-cost, clean generation resources including the retirement of the SJGS and expiration of leased capacity from PVNGS. The request also includes updated depreciation rates for natural gas plants to align with the Company’s 2040 carbon-free portfolio goal. See Note 12.

Financial and Business Objectives

PNMR is focused on achieving three key financial objectives:

•Earning authorized returns on regulated businesses

•Delivering at or above industry-average earnings and dividend growth

•Maintaining investment grade credit ratings

In conjunction with these objectives, PNM and TNMP are dedicated to:

•Maintaining strong employee safety, plant performance, and system reliability

•Delivering a superior customer experience

•Demonstrating environmental stewardship in business operations, including transitioning to an emissions-free generating portfolio by 2040

•Supporting the communities in their service territories

Earning Authorized Returns on Regulated Businesses

PNMR’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.

Fair and timely rate treatment from regulators is crucial to PNM and TNMP in earning their allowed returns and critical for PNMR to achieve its financial objectives. PNMR 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 2022 Annual Reports on Form 10-K.

The Energy Transition Act (“ETA”)

On June 14, 2019, Senate Bill 489, known as the ETA, became effective. 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 Note 11 and in Note 16 of the Notes to Consolidated Financial Statements in the 2022 Annual Reports on Form 10-K.

The ETA has and will have a significant impact on PNM’s future generation portfolio, including PNM’s retirement of SJGS in 2022 and the planned Four Corners exit in 2024 (subject to regulatory approval). PNM cannot predict the full impact of the ETA on potential future generating resource abandonment and replacement filings with the NMPRC.

State Regulation

SJGS Abandonment Application – As discussed in Note 12, in 2019, PNM filed the SJGS Abandonment Application

Table of Contents

with the NMPRC. The application included several replacement resource scenarios including PNM's recommended replacement scenario, which is consistent with PNM's goal of having a 100% emissions-free generating portfolio by 2040 and would have provided cost savings to customers while preserving system reliability.

The NMPRC issued an order requiring the SJGS Abandonment Application be considered in two proceedings: one addressing SJGS abandonment and related financing and the other addressing replacement resources but did not definitively indicate if the abandonment and financing proceedings would be evaluated under the requirements of the ETA. After several requests for clarification and legal challenges, in 2020, the NM Supreme Court ruled the NMPRC is required to apply the ETA to all aspects of PNM’s SJGS Abandonment Application, and that any previous NMPRC orders inconsistent with their ruling should be vacated.

In 2020, the NMPRC issued an order which authorized PNM to abandon SJGS by June 30, 2022, to issue Securitized Bonds of up to $361 million, and to establish the Energy Transition Charge. The NMPRC's order required an interim rate rider adjustment upon the start date of the Energy Transition Charge to provide immediate credits to customers for the full value of PNM’s revenue requirement related to SJGS until those reductions are reflected in base rates. In addition, PNM was granted authority to establish regulatory assets to recover costs that PNM will pay prior to the issuance of the Securitized Bonds, including costs associated with the bond issuances as well as for severances, job training, and economic development funds. Later that year, the NMPRC issued an order approving replacement resource selection criteria identified in the ETA that include PPAs for 650 MW of solar and 300 MW of battery storage.

On February 28, 2022, WRA and CCAE filed a joint motion for order to show cause and enforce financing order and supporting brief, which requested that the NMPRC order PNM to show cause why its rates should not be reduced at the time SJGS is abandoned, and to otherwise enforce the NMPRC’s April 1, 2020 final order.

On June 17, 2022, the hearing examiners issued a recommended decision requesting the NMPRC issue an order that would require PNM to:

•Revise its rates to remove all of the costs of SJGS Unit 1 by issuing rate credits of $21.1 million on an annual basis, to customers by July 1, 2022

•Revise its rates again, to remove all costs of SJGS Unit 1, Unit 4, and common facilities by increasing the rate credits to $98.3 million on an annual basis, by October 1, 2022

•Transfer payments due and owing to the Indian Affairs Fund, Economic Development Assistance Fund, and the Displaced Workers Assistance Fund within 30 days of the abandonment of SJGS Unit 1

On June 29, 2022, the NMPRC issued its final order adopting and approving the recommended decision in its entirety with certain additions. The additions to the final order include requirements for PNM to file a report no later than October 15, 2022, that contains a record of all of its costs incurred in the show cause proceeding so that the prudence of those costs will be known and be subject to review in PNM's future rate case and that the prudency review shall include a compliance filing to enable a review of the prudence of PNM's decision to delay issuance of the Securitized Bonds beyond the dates of the SJGS abandonment. On June 30, 2022, PNM filed a Notice of Appeal and an Emergency Motion for Partial Interim Stay of the NMPRC's Final Order with the NM Supreme Court. Subsequently, on July 25, 2022, PNM filed another emergency motion seeking an immediate and ongoing stay from the NM Supreme Court for the pendency of the appeal. In the interim, PNM began issuing rate credits effective July 31, 2022 and PNM made payments totaling $19.8 million to the Indian Affairs Fund, Economic Development Assistance Fund, and the Displaced Workers Assistance Fund. On September 2, 2022, the NM Supreme Court issued an order granting PNM's July 25, 2022 motion for partial stay and as a result PNM suspended issuing rate credits. On October 14, 2022, PNM made its required compliance filing under the NMPRC's June 29, 2022 final order. On November 1, 2022, the NM Supreme Court issued an order continuing the partial stay of the rate credits during the pendency of the appeal. See Notes 11 and 12.

Four Corners Abandonment Application - In early 2021, PNM filed the Four Corners Abandonment Application, which sought NMPRC approval to exit PNM’s 13% share of Four Corners as of December 31, 2024, and issuance of approximately $300 million of Securitized Bonds as provided by the ETA. PNM's filing provided background on the NMPRC's consideration of the prudence of PNM's investment in Four Corners explained how the proposed sale and abandonment provides a net public benefit. 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. See additional discussion of the ETA and PNM’s Four Corners Abandonment Application in Notes 11 and 12.

PNM enhanced its plan to exit Four Corners and emphasized its ESG strategy to reduce carbon emissions on March 12, 2021 with an announcement for additional plans allowing for seasonal operations at Four Corners beginning in the fall of 2023,

Table of Contents

subject to the necessary approvals, including PNM's Four Corners Abandonment Application at the NMPRC. The solution for seasonal operations ensures the plant will be available to serve each owners' customer needs during times of peak energy use while minimizing operations during periods of low demand. This approach would result in an estimated annual 20 to 25 percent reduction in carbon emissions at the plant and retains jobs and royalty payments for the Navajo Nation.

PVNGS Leased Interest Abandonment Application - On April 2, 2021, PNM filed the PVNGS Leased Interest Abandonment Application. In the application PNM requested NMPRC authorization to decertify and abandon its Leased Interest and to create regulatory assets for the associated remaining undepreciated investments with consideration of cost recovery of the undepreciated investments in a future rate case. PNM also sought NMPRC approval to sell and transfer the PNM-owned assets and nuclear fuel supply associated with the Leased Interest to SRP, which will be acquiring the Leased Interest from the lessors upon termination of the existing leases. In addition, PNM sought NMPRC approval for a 150 MW solar PPA combined with a 40 MW battery storage agreement, and a stand-alone 100 MW battery storage agreement to replace the Leased Interest. To ensure system reliability and load needs are met in 2023, when a majority of the leases expire, PNM also requested NMPRC approval for a 300 MW solar PPA combined with a 150 MW battery storage agreement.

On August 25, 2021, the NMPRC issued an order confirming PNM requires no further NMPRC authority to abandon the PVNGS Leased Interest and to sell and transfer the PNM-owned assets and nuclear fuel supply associated with the Leased Interest to SRP. The order bifurcated the issue of approval of the two PPAs and three battery storage agreements into a separate docket so it may proceed expeditiously and deferred a ruling on the other issues. On November 1, 2022, ABCWUA, Bernalillo County, CCAE, NEE, NM AREA, the NMAG, WRA, and Staff filed a Joint Motion for Accounting Order to require PNM to track in a regulatory liability, all costs associated with the PVNGS Leased Interests that will be abandoned in January 2023 and January 2024 that are still being collected in rates, which PNM opposes. On November 18, 2022, the NMPRC issued its order on Joint Motion for Accounting Order requiring PNM to establish a regulatory liability to track and account for, upon termination of the PVNGS leases, all costs currently borne by ratepayers associated with those leases during pendency of the 2024 Rate Change, subject to a determination of ratemaking treatment. In addition, PNM may establish a regulatory asset account to record undepreciated investment for improvements to the Unit 1 and Unit 2 Leased Interests upon termination of the leases, and to record cost differences in the proceeds from SRP for the sale of the PVNGS Leased Assets and the actual book value for which recovery of these costs will be determined in the 2024 Rate Change. The NMPRC order also states that in its general rate case PNM must address unresolved issues including whether PNM’s decision to renew the five leases and the repurchase of 64.1 MW in PVNGS Unit 2 capacity exposed ratepayers to additional financial liability beyond that to which they would otherwise would have been exposed, and whether PNM should be denied recovery of future decommissioning expenses as a remedy for imprudence. PNM is unable to predict the outcome of this matter.

On February 16, 2022, the NMPRC approved the two PPAs and three battery storage agreements. On June 16, 2022, PNM notified the NMPRC that none of the developers of the two PPAs and three battery storage agreements have moved forward under the terms of the agreements approved by the NMPRC, and none of the replacement resource projects would be operational in 2023. PNM entered into amendments to the 300 MW solar PPA combined with a 150 MW battery storage agreement and proposed those amendments to the NMPRC for approval in a filing with the NMPRC on June 24, 2022. PNM determined the terms offered by the 150 MW solar PPA combined with a 40 MW battery storage agreement and the stand-alone 100 MW battery storage agreement were not satisfactory in comparison with other potential projects that might be utilized instead, and PNM did not support the proposed amendments to those agreements in the June 24, 2022 filing. No party filed objections and the amendments to the 300 MW solar PPA combined with 150 MW battery storage agreement and the decision not to proceed with the other agreements, were deemed approved. On September 2, 2022, PNM entered into amendments to the 150 MW battery storage agreement to increase the capacity to 300 MW and proposed those amendments to the NMPRC for approval. No party filed objections and the 300 MW solar battery storage agreement was deemed approved. PNM anticipates these facilities will be in service in 2024. PNM continues to pursue additional resources to replace the PVNGS leases that were abandoned in January 2023 and will be abandoned in 2024. For additional information on PNM's Leased Interest and the associated abandonment application see Note 13 and Note 12, respectively.

Summer Peak Resource Adequacy - Throughout 2021, 2022 and continuing into 2023, PNM provided notices of delays and status updates to the NMPRC for the approved SJGS replacement resource projects. All four project developers had notified PNM that completion of the projects would be delayed and no longer available for most, if any of the 2022 summer peak load period. While PNM experienced a new system peak retail load of 2,139 MW on July 19, 2022, PNM’s generation resources performed sufficiently with no significant challenges to resource adequacy during the 2022 summer peak season.

Table of Contents

with a range of approximately 11.0% to 16.0% for the 2023 summer peak period. PNM continues to evaluate other potential firm power agreements with various providers, as well as all potential short-term resource options to address these resource adequacy concerns. PNM is unable to predict the outcome of this matter. See Note 12.

2020 Decoupling Petition – In 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. Later in 2020, PNM requested an order to vacate the public hearing and stay 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, which was approved and PNM subsequently filed a petition for declaratory order asking the NMPRC to issue an order finding that full revenue decoupling is authorized by the EUEA. On March 17, 2021, the NMPRC issued an order granting PNM's petition for declaratory order, commencing a proceeding to address petitions. On January 14, 2022, the hearing examiner issued a recommended decision recommending, among other things, that 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. On April 27, 2022, the NMPRC issued an order adopting the recommended decision in its entirety. On May 24, 2022, PNM filed a notice of appeal with the NM Supreme Court. See Note 12. PNM cannot predict the outcome of this matter.

PNM Solar Direct - In 2019, PNM filed an application with the NMPRC for approval of a program under which qualified governmental and large commercial customers could participate in a voluntary renewable energy procurement program. PNM proposed to recover costs of the program directly from subscribing customers through a rate rider. Under the rider, PNM would procure renewable energy from 50 MW of solar-PV facilities under a 15-year PPA. PNM had fully subscribed the entire output of the 50 MW facilities at the time of the filing. In March 2020, the hearing examiner issued a recommended decision recommending approval of PNM’s application that was subsequently approved by the NMPRC. These facilities began commercial operations in the second quarter of 2022.

The Community Solar Act - The Community Solar Act establishes a program that allows for the development of community solar facilities and provides customers of a qualifying utility with the option of accessing solar energy produced by a community solar facility in accordance with the Community Solar Act. The NMPRC is charged with administering the Community Solar Act program, establishing a total maximum capacity of 200 MW community solar facilities (applicable until November 2024) and allocating proportionally to the New Mexico electric investor-owned utilities and participating cooperatives. As required under the Community Solar Act, on March 30, 2022, the NMPRC issued an order that adopted a rule on the administration of the Community Solar Act program. See Note 12.

Advanced Metering – Currently, TNMP has approximately 268,000 advanced meters across its service territory. Beginning in 2019, the majority of costs associated with TNMP’s AMS program are being recovered through base rates. On July 14, 2021, TNMP filed a request with the PUCT to consider and approve its final reconciliation of the costs spent on the deployment of AMS from April 1, 2018 through December 31, 2018 of $9.0 million, and approve appropriate carrying charges until full collection. The PUCT approved substantially all costs on February 10, 2022. In 2020, TNMP filed an application with the PUCT for authorization to implement necessary technological upgrades of approximately $46 million to its AMS program by the second quarter of 2023, which the PUCT approved on January 14, 2021. TNMP is seeking recovery of the investment associated with the upgrade in its DCRF filing. PNM's Grid Modernization Application includes proposals for installation and deployment of advanced metering infrastructure investments. See Note 12.

Rate Riders and Interim Rate Relief – 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. 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.

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 described below, 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

PNMR’s financial objective to deliver at or above industry-average earnings and dividend growth enables investors to

Table of Contents

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. PNMR 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.

PNMR targets a dividend payout ratio in the 50% to 60% range of its ongoing earnings. PNMR 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.

Under the terms of the Merger Agreement, PNMR has agreed not to declare, set aside, make or pay any dividend or other distribution, payable in cash, stock, property or otherwise, with respect to any of its equity securities, or make any other actual, constructive or deemed distribution in respect of any equity securities (except (i) PNMR may continue the declaration and payment of planned regular quarterly cash dividends on PNMR common stock for each quarterly period ended after the date of the Merger Agreement, which for any fiscal quarter in 2023 shall not exceed $0.3675, with usual record and payment dates in accordance with past dividend practice, and (ii) for any cash dividend or cash distribution by a wholly-owned subsidiary of PNMR to PNMR or another wholly-owned subsidiary of PNMR).

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 February 10, 2022, Moody's downgraded TNMP's issuer rating from A3 to Baa1 and changed the outlook from negative to stable. See the subheading Liquidity included in the full discussion of Liquidity and Capital Resources below for the specific credit ratings for PNMR, 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.

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 PNMR’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. PNMR 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".

PNMR 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.

PNMR 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.

The Company continues to monitor developments related to the COVID-19 pandemic and implement safety measures as appropriate. The Company is also working with its suppliers to manage the impacts to its supply chain and remains focused on the integrity of its information systems and other technology systems used to run its business. However, the Company

cannot predict the extent or duration of the ongoing COVID-19 pandemic, its effects on the global, national or local economy, or on the Company's financial position, results of operations, and cash flows. The Company will continue to monitor developments related to COVID-19 and will remain focused on protecting the health and safety of its customers, employees, contractors, and other stakeholders, and on its objective to provide safe, reliable, affordable and environmentally responsible power. As discussed in Note 12, both PNM and TNMP suspended disconnecting certain customers for past due bills, waived late fees during the pandemic, and have been provided regulatory mechanisms to recover these and other costs resulting from COVID-19. See additional discussion below regarding the Company's customer, community, and stakeholder engagement in response to COVID-19.

On April 1, 2021, PNM joined and began participating in the EIM. The EIM is 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. PNM completed a cost-benefit analysis, which indicated participation in the EIM would provide substantial benefits to retail customers. In 2018, PNM filed an application with the NMPRC requesting, among other things, to recover initial capital investments and authorization to establish a regulatory asset to recover other expenses that would be incurred in order to join the EIM. The NMPRC approved the establishment of a regulatory asset but deferred certain rate making issues, including but not limited to issues related to implementation and ongoing EIM costs and savings, the prudence and reasonableness of costs to be included in the regulatory asset, and the period over which costs would be charged to customers until PNM’s next general rate case filing. PNM has experienced an aggregate of $69.5 million in cost savings to customers through participation in the EIM, which includes $22.4 million in the three months ended March 31, 2023. PNM passes the cost savings through to customers under PNM’s FPPAC.

To bolster PNM’s preparations for times of critical need, the Company has joined the Western Resource Adequacy Program ("WRAP"). 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 resources are prioritized for availability in the event New Mexico is critically impacted by a resource emergency.

Utility Plant and Strategic Investments

Utility Plant Investments – During the 2021 and 2022 periods, PNM and TNMP together invested $1.8 billion in utility plant, including substations, power plants, nuclear fuel, and transmission and distribution systems. New Mexico’s clean energy future depends on a reliable, resilient, secure grid to deliver an evolving mix of energy resources to customers. PNM has launched a capital initiative, which emphasizes new investments in its transmission and distribution infrastructure with three primary objectives: delivering clean energy, enhancing customer satisfaction and increasing grid resilience. Projects 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. In addition, projects included in the Grid Modernization Application improve customers’ ability to customize their use of energy and modernize PNM's electric grid through infrastructure and technology improvements. 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.

Strategic Investments – In 2017, PNMR Development and AEP OnSite Partners created NMRD to pursue the acquisition, development, and ownership of renewable energy generation projects, primarily in the state of New Mexico. Abundant renewable resources, large tracts of affordable land, and strong government and community support make New Mexico a favorable location for renewable generation. New Mexico is frequently characterized by its high potential for solar and wind capacity. PNMR Development and AEP OnSite Partners each have a 50% ownership interest in NMRD. Through NMRD, PNMR anticipates being able to provide additional renewable generation solutions to customers within and surrounding its regulated jurisdictions through partnering with a subsidiary of one of the United States’ largest electric utilities. As of March 31, 2023, NMRD’s renewable energy capacity in operation was 135.1 MW, which includes 130 MW of solar-PV facilities to supply energy to the Meta data center located within PNM’s service territory, 1.9 MW to supply energy to Columbus Electric Cooperative located in southwest New Mexico, 2.0 MW to supply energy to the Central New Mexico Electric Cooperative, and 1.2 MW of solar-PV facilities to supply energy to the City of Rio Rancho, New Mexico. In addition, the NMPRC approved PNM to enter into a 50 MW solar PPA to service the Meta data center, which will be owned by NMRD and is expected to be operational in 2023. PNMR Development, together with AEP OnSite Partners, has selected an adviser for the sale of NMRD. Proceeds resulting from the sale will support the funding of regulated capital investments.

the NMPRC's final order which adopted revisions to the IRP Rule. See additional discussion of the NMPRC adopted revision to the IRP Rule in Note 12.

In the second quarter of 2022, PNM initiated its 2023 IRP process which will cover the 20-year planning period from 2023 through 2043. Consistent with historical practice, PNM is receiving public input from interested parties as part of this process. On March 1, 2023, the NMPRC issued an order granting PNM’s Motion for Extension of time to file its 2023 IRP until December 15, 2023, and the deadline for commencing the facilitated stakeholder process was extended until June 15, 2023.

Environmentally Responsible Power

PNMR 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% emissions-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

PNMR’s corporate website (www.pnmresources.com) includes a dedicated section providing key environmental and other sustainability information related to PNM’s and TNMP’s operations and other information that collectively demonstrates the Company’s commitment to ESG principles. This information highlights plans for PNM to be coal-free by 2024 (subject to regulatory approval) and to achieve an emissions-free generating portfolio by 2040.

In February 2022, PNM named its first Chief Sustainability Officer. The Chief Sustainability Officer is 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.

In 2020, PNM announced an agreement to partner with Sandia National Laboratories in research and development projects focused on energy resiliency, clean energy, and national security. The partnership demonstrates PNMR's commitment to ESG principles and its support of projects that further its emissions-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 submitted a Time-of-Day pilot proposal in the 2024 Rate Change filing with the objective of incentivizing 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 on November 15, 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. In addition to the recent filing of PNM's Grid Modernization Application with the NMPRC, the Company is currently monitoring the release of grant opportunities by the U.S. Department of Energy and the State Energy, Minerals and Natural Resources Department, and has applied for funding to supplement the investment in the Grid Modernization Application.

On August 16, 2022, President Biden signed the Inflation Reduction Act of 2022 (the "IRA") into law. The IRA will provide significant benefits for PNMR 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 ownership in the carbon-free PVNGS. Other IRA provisions will encourage transportation electrification with new electric vehicle credits and added incentives in vehicle charging infrastructure. For many of the IRA provisions, additional clarification and detailed guidance from the IRS is still pending.

Electric Vehicles

PNMR is building upon its ESG goal of 100% emissions-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 ESG principles. 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 PNMR’s commitment to increase the electrification of vehicles in its service territory, PNM began to implement the TEP in 2022. 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.

In 2021, PNM announced that it will be joining 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 by the end of 2023.

Other Environmental Matters

Four Corners may be required to comply with environmental rules that affect coal-fired generating units, including regional haze rules and the ETA. On June 19, 2019, EPA repealed the Clean Power Plan, promulgated the ACE Rule, and revised the implementing regulations for all emission guidelines issued under the CAA Section 111(d). On January 19, 2021, the DC Circuit issued an opinion vacating and remanding the ACE Rule, holding that it was based on a misconstruction of Section 111(d) of the CAA, but stayed its mandate for vacatur of the repeal of the Clean Power Plan to ensure that the now-outdated rule would not become effective. The U.S. Supreme Court granted four petitions for certiorari seeking review of the DC Circuit’s decision, and ruled that EPA overstepped its authority under the Clean Power Plan by requiring generation shifting. Relying upon the Major Question Doctrine, the US Supreme Court found no clear statement in the CAA that would authorize EPA to force the power sector to shift from coal-fired power plants to gas-fired power plants and renewable energy resources. The ruling will have an impact on EPA's current drafting of a new rule to replace the ACE Rule, which is expected in Spring 2023.

Renewable Energy

PNM’s renewable procurements include utility-owned solar capacity, as well as solar, wind and geothermal energy purchased under PPAs. As of March 31, 2023, PNM has 158 MW of utility-owned solar capacity in operation. In addition, PNM purchases energy from a customer-owned distributed solar generation program that had an installed capacity of 250.1 MW at March 31, 2023. PNM also owns the 500 KW PNM Prosperity Energy Storage Project. The project was one of the first combinations of battery storage and solar-PV energy in the nation and involved extensive research and development of advanced grid concepts. The facility also was the nation’s first solar storage facility fully integrated into a utility’s power grid. PNM also purchases the output from New Mexico Wind, a 200 MW wind facility, and the output of Red Mesa Wind, an existing 102 MW wind energy center. PNM's 2020 renewable energy procurement plan was approved by the NMPRC in January 2020 and includes a PPA to procure 140 MW of renewable energy and RECs from La Joya Wind II that became operational in June 2021. Under the Solar Direct program discussed above, PNM procures renewable energy from 50 MW of solar-PV facilities under a 15-year PPA. The NMPRC approved the portfolio to replace the retirement of SJGS resulting in PNM executing solar PPAs of 550 MW combined with 270 MW of battery storage agreements. In addition, the PVNGS Leased Interest Abandonment Application approved by the NMPRC includes a 300 MW solar PPA combined with a 300 MW battery storage agreement. The majority of these renewable 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. See additional discussion of the ETA and PNM’s Abandonment Applications in Notes 11 and 12.

As discussed in Strategic Investments above, PNM is currently purchasing the output of 130 MW of solar capacity from NMRD that is used to serve the Meta data center which includes two 25-year PPAs to purchase renewable energy and RECs from an aggregate of approximately 100 MW of capacity from two solar-PV facilities constructed by NMRD to supply power to Meta, Inc. Additionally, PNM has entered into three separate 25-year PPAs to purchase renewable energy and RECs to be used by PNM to supply additional renewable power to the Meta data center. These PPAs include the purchase of power and RECs from two wind projects totaling 216 MW and a 50 MW solar-PV project which began commercial operations in June 2022. In addition, the NMPRC issued an order that will allow PNM to service the Meta data center for an additional 190 MW of solar PPA combined with 50 MW of battery storage and a 50 MW solar PPA.

Table of Contents

On May 3, 2023, PNM filed an application for a CCN for two battery energy storage systems, 6 MW each, located on PNM's distribution system in Valencia and Bernalillo counties. PNM intends to construct, own, and operate these systems that will be interconnected to the distribution system on feeders that currently exceed their existing hosting capacity limits due to the high amount of solar production connected to them. The deployment of battery energy storage systems on these feeders at capacity will bring the power flow on the feeders back within design limits, potentially allowing a number of solar interconnection applications currently on hold to interconnect, which will in turn reduce carbon emissions and the need to curtail solar production in times of oversupply. PNM is requesting approval of the CCN Application, with an estimated total cost of $25.8 million, by December 31, 2023 to support the proposed construction schedule and have the battery energy storage systems begin serving customers in June 2024.

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 2022, incremental energy saved as a result of new participation in PNM’s portfolio of energy efficiency programs was 104 GWh. This is equivalent to the annual consumption of approximately 14,935 homes in PNM’s service territory. PNM’s load management and annual energy efficiency programs also help lower peak demand requirements. In 2022, TNMP’s incremental energy saved as a result of new participation in TNMP’s energy efficiency programs is estimated to be approximately 15 GWh. This is equivalent to the annual consumption of approximately 2,082 homes in TNMP’s service territory. TNMP earned the 2023 Energy Star Partner of the Year - 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 exiting Four Corners in 2024 (subject to regulatory approval) 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 2022, 15 of the Company’s 22 facilities met the solid waste diversion goal of a 65% diversion rate. The Company expects to continue to do well in this area in the future.

Customer, Stakeholder, and Community Engagement

Another key element of the Company’s commitment to ESG principles is fostering relationships with its customers, stakeholders, and communities. The Company strives to deliver a superior customer experience. 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. In the third quarter of 2022, PNM made payments of $19.8 million to promote economic development in areas impacted by the retirement of SJGS. PNM continues to focus its efforts to enhance the customer experience through customer service improvements, including enhanced customer service engagement 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 2022, PNM and the electric utility industry as a whole, have experienced a decline in customer satisfaction as measured by J.D. Power. However, PNM remains focused on continuously improving its customers' experience at every touchpoint and placing greater focus on customer assistance through economic uncertainty.

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. 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 an emissions-free generating portfolio by 2040. PNM also

Table of Contents

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, PNMR's corporate website includes a dedicated section providing additional information regarding the Company’s commitment to ESG principles and other sustainability efforts.

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 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.

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.

Another demonstration of the Company's commitment to ESG principles is the Company’s tradition of supporting the communities it serves in New Mexico and Texas. This support extends beyond corporate giving and financial donations from the PNM Resources Foundation to also include collaborations on community projects, customer low-income assistance programs, and employee volunteerism.

During the three years ending December 31, 2022, corporate giving contributed $10.9 million to civic, educational, environmental, low income, and economic development organizations. In 2023, corporate giving will maintain this strategic focus and continue to highlight corporate citizenship through active involvement with sponsorships demonstrating PNM's commitment to the community. In addition, emergency relief funds in 2022 supported non-profits providing response to the fires in northern and southern New Mexico. Also in December 2022, PNM made donations totaling $150,000 to food banks across the state of New Mexico including tribal communities.

PNMR 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 COVID-19 community needs, PNMR donated to an Emergency Action Fund in partnership with key local agencies to benefit approximately ninety nonprofits and small businesses facing challenges due to lack of technology, shifting service needs, and cancelled fundraising events. 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 Coalition to Stop Violence Against Native Women. PNM also continues to partner in the Light up Navajo project, piloted in 2019 and modeled after mutual aid to connect homes without electricity to the power grid. PNM has partnered with New Mexico universities to enhance intern programs and developed a business coalition model to drive economic development through intern partnerships. PNM has also partnered with key local organizations to initiate funding for programs focused on diversity, equity and inclusion.

Another important outreach program is tailored for low-income customers and includes the PNM Good Neighbor Fund to provide customer assistance with their electric utility bills. COVID-19 has increased the needs of these customers along with customers who may not otherwise need to seek assistance. In addition to the suspension of residential customer disconnections from April 2020 through August 2021 and the expansion of customer payment plans, PNM responded with increased communications through media outlets and customer outreach to connect customers with nonprofit community service providers offering financial assistance, food, clothing, medical programs, and services for seniors. As a result of these communication efforts, 3,488 families in need received emergency assistance through the PNM Good Neighbor Fund during 2022. Additionally, PNM has worked closely with the New Mexico Department of Finance and Administration to implement strategies ensuring customers receive rent benefits, including utility bill assistance, from the Emergency Rental Assistance Program (“ERAP”). As a result of these efforts, the ERAP has paid over $8.7 million in customer arrears since the launch of the program in March 2021.

Additionally, as a part of corporate giving, on October 1, 2020, PNM introduced $2.0 million in funding for the COVID Customer Relief Programs which support income-qualified residential customers and small business customers who have been impacted by the financial challenges created by COVID-19 and have past due electric bills. Qualified customers that pay a portion of their past-due balance can receive assistance toward their remaining balance.

Employee volunteers are the lifeblood of a healthy corporate culture. Community giving through volunteers’ time and effort is at the heart of employee engagement. In 2022, the Company held large-scale volunteer events, working alongside

Table of Contents

nonprofits, schools, and vulnerable communities throughout New Mexico and Texas. Over 450 employees in both states participated in the “Day of Service”, a workday event encouraging employee volunteerism. Throughout 2022, employees volunteered and gave their time generously through their small group and independent volunteer activities and board participation. Volunteers strengthened community resilience by giving 9,171 volunteer hours to support the health, safety, and well-being of diverse communities.

In addition to the extensive engagement both PNM and TNMP have with nonprofit organizations in their communities, the PNM Resources Foundation provides nearly $1.2 million in grant funding each year across New Mexico and Texas. These grants help nonprofits innovate or sustain programs to grow and develop their mission, develop and implement environmental programs, and provide educational opportunities. Beginning in 2020 and ending in 2022, the PNM Resources Foundation funded grants with a three-year focus on decreasing homelessness, increasing access to affordable housing, reducing carbon emissions, and increasing community safety. The PNM Resources Foundation continued to expand its matching and volunteer grant programs and the annual amount of matching donations available to each of its employees was increased. PNM Resources Foundation awarded additional grants to non-profits providing relief for the fires in northern and southern New Mexico in the first half of 2022. The PNM Resources Foundation also approved an increase to the amount awarded to employees, through the employee crisis management fund, who have been affected by the wildfires. In December 2021, the PNM Resources Foundation was nominated for the Albuquerque Business First 2022 Philanthropy Award. In 2023, the Foundation will celebrate its 40th year of serving community needs highlighting education, inclusion, the environment and community vitality.

Economic Factors

PNM – In the three months ended March 31, 2023, PNM experienced an increase of 1.1% in weather normalized residential load. Weather normalized commercial load experienced an increase of 4.9% compared to 2022. In addition, PNM experienced a decrease in industrial load of 8.1% compared to 2022.

TNMP – In the three months ended March 31, 2023, TNMP experienced a decrease of 1.3% in volumetric weather normalized retail load compared to 2022. Weather normalized demand-based load, excluding retail transmission consumers increased 26.3% in the three months ended March 31, 2023 compared to 2022.

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 PNMR were $55.0 million, or $0.64 per diluted share in the three months ended March 31, 2023 compared to $16.0 million, or $0.19 per diluted share in 2022. Among other things, earnings in the three months ended March 31, 2023 benefited from higher weather normalized retail load at PNM, higher transmission margin at PNM and TNMP, higher demand-based load at TNMP, higher distribution rates at TNMP, increased performance on PNM's NDT, coal mine reclamation and SJGS decommissioning investment securities, and decreased operational and maintenance expense and depreciation at PNM primarily due to the retirement of SJGS and the disposition of the PVNGS Unit 1 Leased Interest. These increases were partially offset by milder weather at TNMP, higher employee related, outside services and vegetation management expenses at PNM and TNMP, increased depreciation and property taxes at TNMP due to increased plant in service, lower AMS carrying charges at TNMP, 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

PNMR and PNM have revolving credit facilities with capacities of $300.0 million and $400.0 million that expire in October 2025. Starting in November 2024, the revolving credit facilities will adjust to $285.0 million for PNMR and $380.0 million for PNM until October 2025, with a one-year extension option that, if exercised, would extend the maturity to October 2026, subject to approval by a majority of the lenders. Both facilities provide for short-term borrowings and letters of credit. In addition, PNM has a $40.0 million revolving credit facility that expires in May 2026, and TNMP has a $100.0 million revolving credit facility that expires in September 2025 with a one-year extension option that, if exercised, would extend the maturity to September 2026, subject to approval by a majority of the lenders. Total availability for PNMR on a consolidated basis was $705.8 million at April 28, 2023. The Company utilizes these credit facilities and cash flows from operations to provide funds for both construction and operational expenditures. PNMR also has intercompany loan agreements with each of its subsidiaries.

Table of Contents

PNMR projects that its consolidated capital requirements, consisting of construction expenditures and dividends, will total $5.2 billion for 2023 - 2027, including amounts expended through March 31, 2023. These construction expenditures include expenditures for PNM’s capital initiatives that 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 Grid Modernization Application.

As discussed in Note 9, in November 2022, PNMR entered into a distribution agreement, pursuant to which the Company may sell, from time to time, up to an aggregate sales price of $200.0 million of its common stock, no par value, through sales agents under the PNMR 2022 ATM Program. During the first quarter of 2023, PNMR entered into the 2023 Forward Sale Agreements relating to the sale of 504,452 shares and 528,082 shares of common stock, at an average initial forward sale price of $48.49 per share and $48.30 per share, respectively.

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 2022 Annual Reports on Form 10-K.

After considering the effects of these financings and the Company's short-term liquidity position as of April 28, 2023, the Company has consolidated maturities of long-term and short-term debt aggregating approximately $541.1 million through May 2024. 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 2023-2027 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 March 31, 2023 and April 28, 2023, the Company was in compliance with its debt covenants.

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) PNM purchases renewable energy for a large customer under a special service rate on the customer’s behalf and delivers the energy to the customer’s location. PNM charges the customer for the cost of the renewable energy as a direct pass through to the customer and includes the associated GWh in the table above.

(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) Decrease primarily reflects termination of agreements to sell power from SJGS Unit 4 in 2022, including energy related to merchant capacity of 65 MW and the 100 MW hazard sharing agreement with Tri-State.

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.

Financing Activities

See Note 7 of the Notes to Consolidated Financial Statements in the 2022 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 continuing to closely monitor developments and is taking steps to mitigate the potential risks related to COVID-19. The Company is also 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 extent or duration of the COVID-19 outbreak, 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 PNMR 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

Table of Contents

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 April 28, 2023, PNM entered into the PNM 2023 Note Purchase Agreement for the sale and issuance of $200.0 million aggregate principal amount of two series of senior unsecured notes offered in private placement transactions. PNM issued $150.0 million of the PNM 2023 SUNs at 5.51%, due April 28, 2035, and another $50.0 million at 5.92%, due April 28, 2053. Proceeds from the PNM 2023 SUNs were used to repay borrowings under the PNM Revolving Credit Facility and the PNM New Mexico Credit Facility, funding of capital expenditures and for general corporate purposes.

On April 28, 2023, TNMP entered into the TNMP 2023 Bond Purchase Agreement for the sale of $185.0 million aggregate principal amount of two series of TNMP first mortgage bonds offered in private placement transactions. TNMP issued the first series of $130.0 million of the TNMP 2023 Bonds on April 28, 2023, at a 5.01% interest rate, due April 28, 2033. The second series of $55.0 million will be issued on or before July 28, 2023, at a 5.47% interest rate, due July 28, 2053. The proceeds were used to repay borrowings under the TNMP Revolving Credit Facility and for other corporate purposes.

As discussed in Note 9, in November 2022, PNMR entered into the PNMR 2022 ATM Program. During the first quarter of 2023, PNMR entered into forward sale agreements with each of Bank of America, N.A. and Wells Fargo Bank, N.A. as forward purchasers relating to the sale of 504,452 shares and 528,082 shares of common stock, respectively, under the PNMR 2022 ATM Program. The average initial forward sale price of $48.49 per share and $48.30 per share, respectively, are subject to adjustments based on a net interest rate factor and by future dividends paid on PNMR common stock as specified in the forward sale agreements. PNMR 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 dates. Refer to Note 9 for information regarding The Company's settlement options and related accounting treatment. As of March 31, 2023, no shares have been settled under the 2023 Forward Sale Agreements.

On March 15, 2023, PNMR entered into an approximately 6-month hedging arrangement, effective March 17, 2023, for $150.0 million to hedge an equal amount of its variable rate debt, whereby it effectively established a fixed interest rate of 4.57%. On March 15, 2023, PNMR entered into two separate 12-month hedging arrangements, effective January 1, 2024, for $150.0 million each, totaling $300.0 million, to hedge an equal amount of its variable rate debt, whereby it effectively established fixed interest rates of 3.57% and 3.62%. On May 4, 2023, PNMR entered into three separate 12-month hedging arrangements, effective January 1, 2024, for $100.0 million each, totaling $300.0 million to hedge an equal part of its variable rate debt, whereby it effectively established fixed interest rates of 3.32%, 3.32%, and 3.38%. All of these hedging agreements establish the fixed rate indicated for the indicated amount of variable rate debt, above which a customary spread over SOFR is applied, which is subject to change if there is a change in PNMR's credit rating. These hedge agreements will also be accounted for as cash flow hedges.

expansion in New Mexico. The ability of PNMR to pay dividends on its common stock is dependent upon the ability of PNM and TNMP to pay dividends to PNMR. See Note 6 of the Notes to the Consolidated Financial Statements in the 2022 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 three months ended March 31, 2023, PNMR 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 $55.0 million of SUNs that mature in May 2023, and $130.0 million of PCRBs that mature in June 2023. 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

PNMR’s liquidity arrangements include the $300.0 million PNMR Revolving Credit Facility, the $400.0 million PNM Revolving Credit Facility, and the $100.0 million TNMP Revolving Credit Facility. In January 2023, both PNMR and PNM exercised a one-year extension option on their respective credit facilities, extending maturity through October 2025; provided that, effective November 1, 2024, the amount of the PNMR Revolving Credit Facility will adjust to $285.0 million and the amount of the PNM Revolving Credit Facility will adjust to $380.0 million because one lender in each facility did not agree to the one-year extension to October 2025. Both credit facilities contain an additional one-year extension option that, if exercised, would extend the maturity through October 2026, subject to approval by a majority of the lenders. PNM also has the $40.0 million PNM New Mexico Credit Facility through May 20, 2026. In January 2023, TNMP exercised a one-year extension option on the TNMP Revolving Credit Facility, extending the maturity to September 23, 2025, The TNMP Revolving Credit Facility contains an additional one-year extension option that, if exercised, would extend the maturity to September 23, 2026, subject to approval by a majority of the lenders. Variable interest rates under the PNMR, 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 sell 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:

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 2023-2027 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 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.

In addition to the above, PNMR has $30.3 million of letters of credit issued under the WFB LOC Facility. See Note 9. The above table excludes intercompany debt. As of April 28, 2023, PNM, TNMP, and PNMR Development had $6.2 million of borrowings from PNMR under their intercompany loan agreements and PNMR had no in intercompany borrowings from PNMR Development. The remaining availability under the revolving credit facilities at any point in time varies based on a number of factors, including the timing of collections of accounts receivables and payments for construction and operating expenditures.

PNMR has an automatic shelf registration that provides for the issuance of various types of debt and equity securities that expires March 2025. PNM has a shelf registration statement for up to $650.0 million of senior unsecured notes that expires in May 2023.

Other Material Cash Requirements

PNMR, PNM, and TNMP have contractual obligations for long-term debt, minimum lease payments, coal contracts, coal mine reclamation, nuclear decommissioning, SJGS plant decommissioning, pension and retiree medical contributions, and certain other long-term obligations. See MD&A – Other Material Cash Requirements in the 2022 Annual Reports on Form 10-K.

Contingent Provisions of Certain Obligations

As discussed in the 2022 Annual Reports on Form 10-K, PNMR, 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, PNMR, 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 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 environmental equipment, 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

100

Table of Contents

federal and/or state regulation of GHG. Management has published, with Board oversight, a Climate Change Report available at http://www.pnmresources.com/about-us/sustainability-portal.aspx, that details the Company’s efforts to transition to an emissions-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 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 2022, GHG associated with PNM’s interests in its fossil-fueled generating plants included approximately 4.8 million metric tons of CO2, which comprises the vast majority of PNM’s GHG.

As of March 31, 2023, approximately 45% of PNM’s generating capacity, including resources owned, leased, and under PPAs, all of which is located within the U.S., consisted of coal or gas-fired generation that produces GHG and reflects the retirement of SJGS. As PNM shifts its generation to cleaner energy resources the Company’s output of GHG 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.

PNM has several programs underway to reduce or offset GHG from its generation resource portfolio, thereby reducing its exposure to climate change regulation. As described in Note 16 of the Notes to Consolidated Financial Statements in the 2022 Annual Reports on Form 10-K, PNM received approval for the December 31, 2017 shutdown of 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 for the entire station of approximately 54% for 2018, reflecting a reduction of 32% of GHG from the Company’s owned interests in SJGS, below 2005 levels. In 2020, PNM received authorization for a June 2022 abandonment of SJGS Units 1 and 4. On February 17, 2022, PNM notified the NMPRC that PNM had acquired permission of the SJGS owners and coal mine to temporarily extend operation of SJGS Unit 4 until September 30, 2022. On June 30, 2022, SJGS Unit 1 shut down and on September 30, 2022, SJGS Unit 4 ceased operations. In addition, PNM has filed the Four Corners Abandonment Application with the NMPRC for approval to sell its ownership interest in Four Corners by the end of 2024, although the NMPRC denied PNM's abandonment of Four Corners on December 15, 2021. On December 22, 2021, PNM filed a Notice of Appeal with the NM Supreme Court of the NMPRC decision to deny the application. On January 21, 2022, PNM filed its Statement of Issues regarding the appeal and on March 24, 2022, PNM filed its Brief in Chief. On March 28, 2023, the NM Supreme Court heard oral arguments on the appeal. See additional discussion of the SJGS and Four Corners Abandonment in Note 12. Retiring PNM’s share of SJGS in 2022 resulted in a GHG reduction from 2021 levels of 67% and exiting participation in Four Corners would result in a total reduction of approximately 88% of PNM's GHG emissions based upon 2021 GHG emissions from generation.

As of March 31, 2023, PNM owns 158 MW of solar facilities in commercial operation. In addition, PNM purchases renewable power under long-term PPAs to serve New Mexico retail customers, including the data center located in PNM's service territory. At March 31, 2023, renewable energy procured under these agreements from wind, solar-PV, and geothermal facilities aggregated to 658 MW, 230 MW, and 11 MW. These agreements currently have expiration dates beginning in January 2035 and extending through May 2047. The NMPRC has approved PNM’s request to enter into additional PPAs for renewable energy for an additional 1,090 MW of energy from solar-PV facilities combined with 620 MW of battery storage agreements with an anticipated 400 MW of solar and 170 MW of battery storage expected to come online in 2023. The entire portfolio of replacement resources approved by the NMPRC in PNM’s SJGS Abandonment Application includes replacement of SJGS capacity with the procurement of 550 MW of solar PPAs combined with 270 MW of battery storage agreements. The PVNGS Leased Interest Abandonment Application approved by the NMPRC for replacement of 114 MW of PVNGS capacity and to ensure system reliability and load needs are met includes procurement of 300 MW of solar PPA combined with 300 MW

of battery storage agreements. In addition, the NMPRC issued an order that will allow PNM to service a data center for an additional 190 MW of solar PPA combined with 50 MW of battery storage with an operational date in 2024 and a 50 MW solar PPA expected to be operational in 2023. Approval of these renewable energy and battery resources should further reduce any exposure to GHG emissions risk. 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 250.1 MW at March 31, 2023. PNM’s distributed solar programs will generate an estimated 500.2 GWh of emission-free solar energy available this year to offset PNM’s annual production from fossil-fueled electricity generation. 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 6,686 GWh of electricity through 2022. Over the next 20 years, PNM projects energy efficiency and load management programs will provide the equivalent of approximately 1,155 GWh of electricity savings, which will avoid an estimated 1.0 million metric tons of CO2 based upon projected emissions from PNM’s system-wide 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.

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 such as air cooling, use of grey water, improved reservoir operations, and shortage sharing arrangements with other water users 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; however, PNM remains at risk for wildfires outside of its control and the resulting damages in its service areas.

EPA Regulation

In April 2007, the US Supreme Court held that EPA has the authority to regulate GHG under the CAA. This decision heightened the importance of this issue for the energy industry. In December 2009, EPA released its endangerment finding for GHG from new motor vehicles, stating that the atmospheric concentrations of six key greenhouse gases (CO2, methane, nitrous oxides, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride) endanger the public health and welfare of current and future generations. In May 2010, EPA released the final Prevention of Significant Deterioration (“PSD”) and Title V Greenhouse Gas Tailoring Rule to address GHG from stationary sources under the CAA permitting programs. The purpose of the rule was to “tailor” the applicability of two programs, the PSD construction permit and Title V operating permit programs, to avoid impacting millions of small GHG emitters. On June 23, 2014, the US Supreme Court found EPA lacked authority to “tailor” the CAA’s unambiguous numerical thresholds of 100 or 250 tons per year, and thus held EPA may not require a source to obtain a PSD permit solely on the basis of its potential GHG. However, the court upheld EPA’s authority to apply the PSD program for GHG to “anyway” sources - those sources that are required to comply with the PSD program for other non-GHG pollutants.

On June 25, 2013, then President Obama announced his Climate Action Plan, which outlined how his administration planned to cut GHG in the U.S., prepare the country for the impacts of climate change, and lead international efforts to combat and prepare for global warming. The plan proposed actions that would lead to the reduction of GHG by 17% below 2005 levels by 2020.

On August 3, 2015, EPA responded to the Climate Action Plan by issuing (1) the Carbon Pollution Standards for new, modified, and reconstructed power plants (under Section 111(b)); and (2) the Clean Power Plan for existing power plants (under Section 111(d)).

102

Table of Contents

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.

Multiple states, utilities, and trade groups filed petitions for review in the DC Circuit to challenge 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.

On June 19, 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. finding that EPA misinterpreted the CAA when it determined that the language of section 111 unambiguously barred consideration of emissions reductions options that were not applied at the source. As a result, the court vacated the ACE Rule and remanded the record to EPA for further consideration consistent with the court’s opinion. While the D.C. Circuit rejected the ACE Rule, it did not reinstate the Clean Power Plan. EPA filed a motion seeking a partial stay of the mandate as to the repeal of the Clean Power Plan, to ensure the court’s order will not render effective the now out-of-date Clean Power Plan. On February 22, 2021, the DC Circuit granted EPA’s motion, indicating that it would 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. On October 29, 2021, the US Supreme Court granted four petitions for certiorari seeking review of the DC Circuit’s decision vacating the ACE Rule and the repeal of the Clean Power Plan. Oral arguments in the US Supreme Court were held on February 28, 2022 and on June 30, 2022, the US Supreme Court ruled in the case. The Court held 6 to 3 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 also expressly invoked the major question doctrine as a basis for rejecting EPA's statutory interpretation. The basic principle of the major question doctrine is that, if an agency seeks to decide an issue of "vast economic or political significance," its action must be supported by clear statutory authorization. In cases where there is no authority, courts need not defer to the agency's statutory interpretation. 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. EPA has indicated it is developing a proposed rule under CAA Section 111(d) to establish guidelines for CO2 emissions from existing EGUs. EPA anticipates issuing a proposed rule for this action in Spring 2023, and promulgating a final rule by Summer 2024.

On January 20, 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. EPA is reconsidering the ACE Rule pursuant to this executive order.

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.’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

103

Table of Contents

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.

On August 16, 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, and carbon capture.

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 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 CO2 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. In its 2020 filing for Four Corners Abandonment, PNM analyzed resource portfolio plans for scenarios that assumed Four Corners will operate through 2031 and for scenarios that assumed PNM will exit Four Corners at the end of 2024. The key findings of the analysis include that exiting Four Corners in 2024 (subject to regulatory approval) would provide long-term economic benefits to PNM’s customers. See Note 12.

The ETA was signed into New Mexico state law and became effective on June 14, 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 CO2 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. 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, and other costs that have not yet been charged to 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 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. See additional discussion of the ETA in Note 11.

The ETA has a significant impact on PNM’s future generation portfolio. In compliance with the ETA, on June 15, 2022, 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. An informal comment period for the draft proposal ran from June 15, 2022 through June 29, 2022. On July 1, 2022, NMED requested the Environmental Improvement Board to docket the matter and set a schedule for pre-filed technical testimony which was filed on September 14, 2022, pre-filed rebuttal testimony which was filed on October 12, 2022, and a public hearing that was held on October 26 and 27, 2022. On October 28, 2022, the rule was passed which adopts new carbon emission standards for new and existing coal-fired power plants.

In February 2020, the hearing examiners assigned to the SJGS abandonment and financing proceedings issued recommended decisions recommending approval of PNM’s abandonment application and for the issuance of Securitized Bonds consistent with the requirements of the ETA. On April 1, 2020, the NMPRC approved the hearing examiners' recommendation to approve PNM's application to retire its share of SJGS in 2022 and for the issuance of Securitized Bonds. PNM has also requested approval of energy transition bonds for the Four Corners Abandonment costs of that transition away from coal-fired generation. On December 15, 2021, the NMPRC denied 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. PNM cannot predict the full impact of the ETA or the outcome of the NM Supreme Court decision with respect to the abandonment of Four Corners. See additional discussion of PNM’s SJGS and Four Corners Abandonment Applications 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.

On December 12, 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. On June 1, 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 includes PNM’s retirement of its share of the SJGS in 2022 and assumes exiting Four Corners in either 2024 or 2031 and PNM has set a goal to have a 100% emissions-free generating portfolio by 2040. While the Company has not conducted an independent 2 Degree Scenario analysis, our commitment to becoming 100% emissions-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 emissions economy-wide by 2050. On April 1, 2020, the NMPRC approved PNM’s application to retire its share of SJGS in 2022. PNM filed for abandonment of Four Corners on January 8, 2021. See Note 12.

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. See Notes 11 and 12. While PNM currently expects the retirement of SJGS in 2022 will provide savings to customers, 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

105

Table of Contents

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.

Financial Reform Legislation

The Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank Reform Act”), enacted in July 2010, includes provisions that will require certain over-the-counter derivatives, or swaps, to be centrally cleared and executed through an exchange or other approved trading facility. It also includes provisions related to swap transaction reporting and record keeping and may impose margin requirements on swaps that are not centrally cleared. The U.S. Commodity Futures Trading Commission (“CFTC”) has published final rules defining several key terms related to the act and has set compliance dates for various types of market participants. The Dodd-Frank Reform Act provides exemptions from certain requirements, including an exception to the mandatory clearing and swap facility execution requirements for commercial end-users that use swaps to hedge or mitigate commercial risk. PNM has elected the end-user exception to the mandatory clearing requirement. PNM expects to be in compliance with the Dodd-Frank Reform Act and related rules within the time frames required by the CFTC. However, as a result of implementing and complying with the Dodd-Frank Reform Act and related rules, PNM’s swap activities could be subject to increased costs, including from higher margin requirements. At this time, PNM cannot predict the ultimate impact the Dodd-Frank Reform Act may have on PNM’s financial condition, results of operations, cash flows, or liquidity.

Other Matters

See Notes 11 and 12 herein and Notes 16 and 17 of the Notes to Consolidated Financial Statements in the 2022 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 PNMR, 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 March 31, 2023, there have been no significant changes with regard to the critical accounting policies disclosed in PNMR’s, PNM’s, and TNMP’s 2022 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. 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 three months ended March 31, 2023, and the year ended December 31, 2022, 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 three months ended March 31, 2023 and 2022, the effects of mark-to-market commodity derivative instruments had no impact to PNM's net earnings and $17.2 million and $2.1 million of fair value losses have been recorded as a regulatory asset. All of the fair values as of March 31, 2023, were determined based on prices provided by external sources other than actively quoted market prices. The net mark-to-market amounts will settle by the end of 2023.

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
March 31, 2023
Rating (1)	Credit Risk Exposure(2)		Number of Counter-parties >10%	Net Exposure of Counter-parties >10%

Table of Contents

(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 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 March 31, 2023, PNMR held $0.2 million of cash collateral to offset its credit exposure.

Net credit risk for the Company’s largest counterparty as of March 31, 2023, was $7.0 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. PNMR'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 PNMR in May, September, October 2022 and March 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 PNMR, PNM, and TNMP revolving credit facilities and term loans are based on SOFR. At April 28, 2023, 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:
PNMR Revolving Credit Facility	6.47	%	$	88,200	$	300,000
PNM Revolving Credit Facility	6.15		26,400		400,000
PNM New Mexico Credit Facility	6.31		5,000		40,000
TNMP Revolving Credit Facility	5.85		11,500		100,000

			$	131,100	$	840,000
Long-term Debt:
PNMR 2021 Delayed-Draw Term Loan	6.05	%	$	1,000,000

PNM 2022 Term Loan	5.71		225,000


			$	1,225,000

The investments held by PNM in trusts for decommissioning and reclamation had an estimated fair value of $431.3 million at March 31, 2023, of which 56.6% 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 March 31, 2023, the decrease in the fair value of the fixed-rate securities would be 2.1%, or $5.1 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. The NMPRC ruled in the NM 2015 Rate Case that PNM would not be able to include future contributions made by PNM for decommissioning of PVNGS to the extent applicable to certain capacity purchased and leased by PNM in rates charged to retail customers. The NM Supreme Court ruled that the NMPRC’s decision to disallow recovery of such future contributions for decommissioning denied PNM due process and remanded the matter back to the NMPRC for further proceedings. 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 March 31, 2023. These equity securities expose PNM to losses in fair value should the market values of the underlying securities decline. Equity securities comprised 32.6% of the securities held by the trusts as of March 31, 2023. A hypothetical 10% decrease in equity prices would reduce the fair values of these funds by $14.1 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 PNMR, 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 Chief Financial Officer of each of PNMR, 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 PNMR’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 March 31, 2023, that have materially affected, or are reasonably likely to materially affect, each of PNMR’s, PNM’s, and TNMP’s internal control over financial reporting.
