Notes to Financial Statements (UNAUDITED)

In the opinion of management, the accompanying unaudited financial statements contain all adjustments necessary to present fairly, in accordance with GAAP, the financial position of SPS as of ~~March 31,~~June 30, 2021 and Dec. 31, 2020; the results of its operations, including the components of net income ~~comprehensive income, cash flows~~ and changes in stockholder’s equity for the three and six months ended ~~March 31,~~June 30, 2021 and 2020; and its cash flows for the six months ended June 30, 2021 and 2020.

All adjustments are of a normal, recurring nature, except as otherwise disclosed. Management has also evaluated the impact of events occurring after ~~March 31,~~June 30, 2021 up to the date of issuance of these financial statements. These statements contain all necessary adjustments and disclosures resulting from that evaluation. The Dec. 31, 2020 balance sheet information has been derived from the audited 2020 financial statements included in the SPS Annual Report on Form 10-K for the year ended Dec. 31, 2020.

These notes to the financial statements have been prepared pursuant to the rules and regulations of the SEC for Quarterly Reports on Form 10-Q. Certain information and note disclosures normally included in financial statements prepared in accordance with GAAP on an annual basis have been condensed or omitted pursuant to such rules and regulations. For further information, refer to the financial statements and notes thereto included in the SPS Annual Report on Form 10-K for the year ended Dec. 31, 2020, filed with the SEC on Feb. 17, 2021. Due to the seasonality of SPS’ electric sales, interim results are not necessarily an appropriate base from which to project annual results.


1. Summary of Significant Accounting Policies

The significant accounting policies set forth in Note 1 to the financial statements in the SPS Annual Report on Form 10-K for the year ended Dec. 31, 2020 appropriately represent, in all material respects, the current status of accounting policies and are incorporated herein by reference.

Credit Losses — In 2016, the FASB issued Financial Instruments - Credit Losses, Topic 326 (ASC Topic 326), which changes how entities account for losses on receivables and certain other assets. The guidance requires use of a current expected credit loss model, which may result in earlier recognition of credit losses than under previous accounting standards.

SPS implemented the guidance using a modified-retrospective approach, recognizing an immaterial cumulative effect charge (after tax) to retained earnings on Jan. 1, 2020. The Jan. 1, 2020 adoption of ASC Topic 326 did not have a significant impact on SPS’ financial statements.

4. Borrowings and Other Financing Instruments

Short-Term Borrowings

SPS meets its short-term liquidity requirements primarily through the issuance of commercial paper and borrowings under its credit facility and the money pool.

Money Pool — Xcel Energy Inc. and its utility subsidiaries have established a money pool arrangement that allows for short-term investments in and borrowings between the utility subsidiaries. Xcel Energy Inc. may make investments in the utility subsidiaries at market-based interest rates; however, the money pool arrangement does not allow the utility subsidiaries to make investments in Xcel Energy Inc.

7. Fair Value of Financial Assets and Liabilities

Fair Value Measurements

Accounting guidance for fair value measurements and disclosures provides a single definition of fair value and requires disclosures about assets and liabilities measured at fair value. A hierarchical framework for disclosing the observability of the inputs utilized in measuring assets and liabilities at fair value is established by this guidance.

•Level 1 — Quoted prices are available in active markets for identical assets or liabilities as of the reporting date. The types of assets and liabilities included in Level 1 are highly liquid and actively traded instruments with quoted prices.

•Level 2 — Pricing inputs are other than quoted prices in active markets, but are either directly or indirectly observable as of the reporting date. The types of assets and liabilities included in Level 2 are typically either comparable to actively traded securities or contracts, or priced with models using highly observable inputs.

•Level 3 — Significant inputs to pricing have little or no observability as of the reporting date. The types of assets and liabilities included in Level 3 are those valued with models requiring significant management judgment or estimation.

Specific valuation methods include:

Cash equivalents — The fair values of cash equivalents are generally based on cost plus accrued interest; money market funds are measured using quoted net asset value.

Interest rate derivatives — The fair values of interest rate derivatives are based on broker quotes that utilize current market interest rate forecasts.

Commodity derivatives — The methods used to measure the fair value of commodity derivative forwards and options utilize forward prices and volatilities, as well as pricing adjustments for specific delivery locations and are generally assigned a Level 2 classification. When contractual settlements relate to inactive delivery locations or extend to periods beyond those readily observable on active exchanges or quoted by brokers, the significance of the use of less observable ~~forecasts of forward prices and volatilities~~inputs on a valuation is evaluated, and may result in Level 3 classification.

Electric commodity derivatives held by SPS include transmission congestion instruments, generally referred to as FTRs, purchased from SPP. FTRs purchased from ana RTO are financial instruments that entitle or obligate the holder to monthly revenues or charges based on transmission congestion across a given transmission path. The value of an FTR is derived from and designed to offset, the cost of transmission congestion. In addition to overall transmission load, congestion is also influenced by the operating schedules of power plants and the consumption of electricity pertinent to a given transmission path. Unplanned plant outages, scheduled plant maintenance, changes in the relative costs of fuels used in generation, weather and overall changes in demand for electricity can each impact the operating schedules of the power plants on the transmission grid and the value of an FTR.

If forecasted costs of electric transmission congestion increase or decrease for a given FTR path, the value of that particular FTR instrument will likewise increase or decrease. Given the limited observability of ~~important~~certain inputs to the value of FTRs between auction processes, including expected plant operating schedules and retail and wholesale demand, fair value measurements for FTRs have been assigned a Level 3. Non-trading monthly FTR settlements are expected to be recovered through fuel and purchased energy cost recovery mechanisms, and therefore changes in the fair value of the yet to be settled portions of most FTRs are deferred as a regulatory asset or liability. Given this regulatory treatment and the limited magnitude of FTRs relative to the electric utility operations of SPS, the numerous unobservable quantitative inputs pertinent to the value of FTRs are ~~insignificant~~immaterial to the financial statements of SPS.

Derivative Instruments Fair Value Measurements

SPS enters into derivative instruments, including forward contracts, for trading purposes and to manage risk in connection with changes in interest rates and electric utility commodity prices.

Interest Rate Derivatives — SPS may enter into various instruments that effectively fix the interest payments on certain floating rate debt obligations or effectively fix the yield or price on a specified benchmark interest rate for an anticipated debt issuance for a specific period. These derivative instruments are generally designated as cash flow hedges for accounting purposes. As of ~~March 31,~~June 30, 2021, accumulated other comprehensive loss related to interest rate derivatives included immaterial net losses expected to be reclassified into earnings during the next 12 months as the related hedged interest rate transactions impact earnings, including forecasted amounts for unsettled hedges, as applicable.

Wholesale and Commodity Trading Risk — SPS conducts various wholesale and commodity trading activities, including the purchase and sale of electric capacity, energy and energy-related instruments, including derivatives. SPS is allowed to conduct these activities within guidelines and limitations as approved by its risk management committee, comprised of management personnel not directly involved in the activities governed by this policy. Sharing of any margins is determined through state regulatory proceedings as well as the operation of the FERC approved joint operating agreement.

Commodity Derivatives — SPS enters into derivative instruments to manage variability of future cash flows from changes in commodity prices in its electric utility operations. This could include the purchase or sale of energy or energy-related products and FTRs.

Consideration of Credit Risk and Concentrations — SPS continuously monitors the creditworthiness of counterparties to its interest rate derivatives and commodity derivative contracts prior to settlement, and assesses each counterparty’s ability to perform on the transactions set forth in the contracts. Impact of credit risk was immaterial to the fair value of unsettled commodity derivatives presented on the balance sheets.

SPS’ most significant concentrations of credit risk with particular entities or industries are contracts with counterparties to its wholesale, trading and non-trading commodity activities.

At ~~March 31,~~June 30, 2021, 2 of the 8 most significant counterparties for these activities, comprising ~~$17~~$13 million, or ~~38%~~36%, of this credit exposure, had investment grade credit ratings from S&P Global Ratings, Moody’s Investor Services or Fitch Ratings. NaN of the 8 most significant counterparties, comprising ~~$27~~$24 million, or ~~61%~~64%, of this credit exposure, were not rated by external ~~rating~~ratings agencies, but based on SPS’ internal analysis, had credit quality consistent with investment grade. NaN of these significant counterparties, comprising an immaterial amount of this credit exposure, had credit quality less than investment grade, based on internal analysis. NaN of these significant counterparties are municipal or cooperative electric entities, RTOs or other utilities.

Impact of Derivative Activities on Income and Accumulated Other Comprehensive Loss — There were 0 gains or immaterial losses related to interest rate derivatives reclassified from accumulated other comprehensive loss into earnings for the three and six months ended ~~March 31,~~June 30, 2021 and 2020, respectively.

Changes in the fair value of FTRs resulting in pre-tax net gains of $2$8 million and ~~immaterial gains~~$10 million recognized for the three and six months ended ~~March 31,~~June 30, 2021, ~~and 2020,~~ respectively, which were reclassified as regulatory assets or liabilities. There were $3 million of pre-tax net losses recognized for the three and six months ended June 30, 2020, respectively, which were reclassified as a regulatory assets or liabilities. The classification as a regulatory asset or liability is based on expected recovery of FTR settlements through fuel and purchased energy cost recovery mechanisms.

FTR settlement losses of $4 million and gains of $3$11 million were recognized for the three and six months ended ~~March 31,~~June 30, 2021, respectively, and were recorded to electric fuel and purchased power. Settlement gains of $2 million and $5 million were recognized for the three and six months ended June 30, 2020, respectively and were recorded to electric fuel and ~~purchased~~purchases power. These derivative settlement gains and losses are shared with electric customers through fuel and purchased energy cost-recovery mechanisms, and reclassified out of income as regulatory assets or liabilities, as appropriate.

SPS had 0 derivative instruments designated as fair value hedges during the three and six months ended ~~March 31,~~June 30, 2021 and 2020.

Recurring Fair Value Measurements — SPS’ derivative assets and liabilities measured at fair value on a recurring basis:

9. Commitments and Contingencies

The following includes commitments, contingencies and unresolved contingencies that are material to ~~SPS’s~~SPS’ financial position.

Legal

SPS is involved in various litigation matters in the ordinary course of business. The assessment of whether a loss is probable or is a reasonable possibility, and whether the loss or a range of loss is estimable, often involves a series of complex judgments about future events. Management maintains accruals for losses probable of being incurred and subject to reasonable estimation. Management is sometimes unable to estimate an amount or range of a reasonably possible loss in certain situations, including but not limited to when (1) the damages sought are indeterminate, (2) the proceedings are in the early stages, or (3) the matters involve novel or unsettled legal theories.

In such cases, there is considerable uncertainty regarding the timing or ultimate resolution of such matters, including a possible eventual loss.

For current proceedings not specifically reported herein, management does not anticipate that the ultimate liabilities, if any, would have a material effect on SPS’ financial statements. ~~Unless otherwise required by GAAP, legal~~Legal fees are generally expensed as incurred.

~~Rate Matters and Other~~

SPP OATT Upgrade Costs — Costs of transmission upgrades may be recovered from other SPP customers whose transmission service depends on capacity enabled by the upgrade under the SPP OATT. SPP had not been charging its customers for these upgrades, even though the SPP OATT had allowed SPP to do so since 2008. In 2016, the FERC granted SPP’s request to recover these previously unbilled charges and SPP subsequently billed SPS approximately $13 million.

In July 2018, SPS’ appeal to the D.C. Circuit over the FERC rulings granting SPP the right to recover previously unbilled charges was remanded to the FERC. In February 2019, the FERC reversed its 2016 decision and ordered SPP to refund charges retroactively collected from its transmission customers, including SPS, related to periods before September 2015.

In March 2020, SPP and Oklahoma Gas & Electric separately filed petitions for review of the FERC’s orders at the D.C. Circuit. SPS has intervened in both appeals in support of the FERC. Any refunds received by SPS are expected to be given back to SPS customers through future rates.

Table of Contents

In October 2017, SPS filed a separate related complaint asserting SPP assessed upgrade charges to SPS in violation of the SPP OATT. In March 2018, the FERC issued an order denying the SPS complaint. SPS filed a request for rehearing in April 2018. The FERC issued a tolling order granting a rehearing for further consideration in May 2018. If SPS’ complaint results in additional charges or refunds, SPS will seek to recover or refund the amount through future SPS customer rates. In October 2020, SPS filed a petition for review of the FERC’s March 2018 order and May 2018 tolling order at the D.C. Circuit. This appeal is stayed pending the outcome of the separate appeal initiated in 2020 by Oklahoma Gas & Electric and SPP.

~~Table of Contents~~

SPP Filing to Assign GridLiance Facilities to SPS Rate Zone — In August 2018, SPP filed a request with the FERC to amend its OATT to include the costs of the GridLiance High Plains, LLC facilities in the SPS rate zone. In a previous filing, the FERC determined that some of these facilities did not qualify as transmission facilities under the SPP OATT. SPP’s proposed tariff changes resulted in an increase in the annual transmission revenue requirement of $10 million per year, with $6 million allocated to SPS’ retail customers. The remaining $4 million would be paid by other wholesale loads in the SPS rate zone. On March 16, 2020, GridLiance also filed additional rate increases for 2020 which would raise their annual revenue requirement to $14 million, with approximately $9 million allocated to SPS’ retail customers. ~~The hearing portion of this proceeding was concluded on Sept. 11, 2020.~~

The initial post-hearing brief was filed on Oct. 27, 2020 and the Administrative Law Judge’s decision on this case is expected on May 3, 2021. The FERC will then rule on the judge’s decision and either sustain it, overturn it, or order further proceedings. SPS has incurred approximately $17 million in associated charges as of March 31, 2021. In August 2020, FERC issued an order on a question certified by the hearing judge for the FERC’s review, in which FERC made certain findings in SPS’ favor regarding the legal standard that applies to the ongoing hearing proceeding. In November 2020, FERC denied GridLiance’s request for rehearing of the August 2020 order. In December 2020, GridLiance filed a petition for review at the D.C. Circuit of the August 2020 and November 2020 orders on the certified question.

The hearing portion of this proceeding was concluded in September 2020. The initial post-hearing brief was filed in October 2020. On June 3, 2021, the Administrative Law Judge issued a recommended decision, subject to FERC approval, that supports that the GridLiance facilities are transmission facilities and eligible for rate recovery under the SPP OATT. The FERC will then rule on the judge’s decision and either sustain it, overturn it, or order further proceedings. SPS has incurred approximately $19 million in associated charges as of June 30, 2021.

Contract Termination — SPS and ~~Lubbock Power & Light are parties to~~LP&L have a 25-year, 170 MW partial requirements contract. In ~~October 2020, Lubbock Power & Light initiated discussions with~~May 2021, SPS ~~concerning the interpretation of contractual terms related to early termination~~ and ~~default. If the parties are unable to reach resolution,~~LP&L finalized a settlement which would terminate the contract ~~calls~~upon LP&L’s move from the SPP to the ERCOT (expected in 2023) or, absent a move by LP&L to ERCOT, upon LP&L’s election. The settlement agreement requires LP&L to pay SPS $78 million (lump sum or annual installments), to the benefit of SPS’ remaining customers. LP&L would remain obligated to pay for SPP transmission charges associated with LP&L’s load in SPP. The settlement agreement is subject to approval by the ~~matter to proceed to arbitration. The amount of any damages depends on multiple factors~~PUCT and ~~is currently unknown.~~FERC.

FERC NOPR on ROE Incentive Adders — In April 2021, the FERC issued a NOPR proposing to limit collection of ROE incentive adders for RTO membership to the first three years after an entity begins participation in an RTO. If adopted as a final rule, following a comment period expected to be complete by the end of 2021 or 2022, ~~NSP-Minnesota, NSP-Wisconsin and~~ SPS would prospectively discontinue charging their current 0.5% ROE incentive adders. Amounts related to a discontinuance of the adder would ultimately be offset by an increase in retail ~~rates.~~rates, following future rate cases.

Environmental

Manufactured Gas Plant, Landfill and Disposal Sites — SPS is ~~currently~~ remediating a former disposal site. SPS has recognized its best estimate of costs/liabilities that will result from final resolution of these issues, however, the outcome and timing is unknown. In addition, there may be insurance recovery and/or recovery from other potentially responsible parties, offsetting a portion of costs incurred.

Leases

SPS evaluates contracts that may contain leases, including PPAs and arrangements for the use of office space and other facilities, vehicles and equipment. A contract contains a lease if it conveys the exclusive right to control the use of a specific asset.

Components of lease expense:


		Three Months Ended March 31					Three Months Ended June 30

VIEs

Under certain PPAs, SPS purchases power from IPPs for which SPS is required to reimburse fuel costs, or to participate in tolling arrangements under which SPS procures the natural gas required to produce the energy that it purchases. These specific PPAs create a variable interest in the IPP.

SPS had approximately 1,197 MW of capacity under long-term PPAs at both ~~March 31,~~June 30, 2021 and Dec. 31, 2020 with entities that have been determined to be VIEs. SPS concluded that these entities are not required to be consolidated in its financial statements because it does not have the power to direct the activities that most significantly impact the entities’ economic performance. The PPAs have expiration dates through 2041.

ITEM 2 — MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Discussion of financial condition and liquidity for SPS is omitted per conditions set forth in ~~general instructions~~General Instructions H(1)(a) and (b) of Form 10-Q for wholly owned subsidiaries. It is replaced with management’s narrative analysis of the results of operations set forth in ~~general instructions~~General Instruction H(2)(a) of Form 10-Q for wholly owned subsidiaries (reduced disclosure format).

Non-GAAP Financial Measures

The following discussion includes financial information prepared in accordance with GAAP, as well as certain non-GAAP financial measures such as, electric margin and ongoing earnings.

Generally, a non-GAAP financial measure is a measure of a company’s financial performance, financial position or cash flows that excludes (or includes) amounts that are adjusted from measures calculated and presented in accordance with GAAP.

~~Table of Contents~~

SPS’ management uses non-GAAP measures for financial planning and analysis, for reporting of results to the Board of Directors, in determining performance-based compensation, and communicating its earnings outlook to analysts and investors. Non-GAAP financial measures are intended to supplement investors’ understanding of our performance and should not be considered alternatives for financial measures presented in accordance with GAAP. These measures are discussed in more detail below and may not be comparable to other companies’ similarly titled non-GAAP financial measures.

Electric Margin

Electric margin is presented as electric revenues less electric fuel and purchased power expenses. Expenses incurred for electric fuel and purchased power are generally recovered through various regulatory recovery mechanisms. As a result, changes in these expenses are generally offset in operating revenues.

Management believes electric margins provide the most meaningful basis for evaluating our operations because they exclude the revenue impact of fluctuations in these expenses.

These margins can be reconciled to operating income, a GAAP measure, by including other operating revenues, O&M expenses, DSM expenses, depreciation and amortization and taxes (other than income taxes).


Results of Operations

SPS’ net income was approximately ~~$58~~$126 million for the ~~three~~six months ended ~~March 31,~~June 30, 2021 compared with approximately ~~$43~~$114 million for the prior year, reflecting higher electric margin ~~(regulatory outcomes in Texas~~(capital investment recovery and ~~New Mexico)~~regulatory outcomes), partially offset by increased ~~depreciation.~~depreciation and O&M expenses.

Electric Margin

Electric revenues and fuel and purchased power expenses tend to vary with changing retail and wholesale sales requirements and unit cost changes in fuel and purchased power. Changes in fuel or purchased power costs can impact earnings as the fuel and purchased power cost recovery mechanisms of the Texas and New Mexico jurisdictions may not allow for complete recovery of all expenses.

Electric revenues and margin:


		Three Months Ended March 31					Six Months Ended June 30
(Millions of Dollars)	(Millions of Dollars)	2021		2020		(Millions of Dollars)	2021		2020

Electric margin	Electric margin	$	241	$	207	Electric margin	$	487	$	432

(a)The increase in revenue and electric fuel and purchased power is primarily due to Winter Storm Uri, resulting in higher fuel prices, as well as additional long-term energy and SPP market purchases.

Non-Fuel Operating Expense and Other Items

Depreciation and Amortization — Depreciation and amortization increased ~~$19~~$33 million, or ~~32.2%~~26.8%, year-to-date. The increase was primarily due to the Sagamore wind farm being placed in service in December 2020, in addition to system expansion. The increase is also due to new FERC transmission rates applied in March 2020 and implementation of new depreciation rates in both New Mexico and Texas as part of regulatory outcomes in 2020.

O&M Expenses — O&M expenses increased $14 million, or 10.9%, year-to-date. The increase was primarily due to expenses related to new wind farms and software infrastructure & security costs, partially offset by continuous improvement initiatives. Timing impacts also occurred throughout 2020 due to cost control initiatives to mitigate the adverse impact of COVID-19 on sales.

AFUDC, Equity and Debt — AFUDC decreased $8$17 million for the first ~~quarter~~six months of 2021, primarily due to construction of the Sagamore wind farm and various transmission construction projects during 2020.

Income Taxes — Income tax benefit increased ~~$12~~$26 million for the first ~~quarter~~six months of 2021. The increase was primarily driven by an increase in wind PTCs. Wind PTCs are largely credited to customers (recorded as a reduction to revenue) and do not have a material impact on net income.

See Note 6 to the financial statements for further information.

Winter Storm Uri

In ~~mid-February~~February 2021, the central portion of the United States experienced a major winter storm (Winter Storm Uri). Extreme cold temperatures impacted certain operational assets as well as the availability of renewable generation across the region. The cold weather also affected the country’s supply and demand for natural gas. These factors contributed to extremely high market prices for natural gas and electricity. ~~Despite the extreme conditions, SPS’ customers experienced minimal disruptions as a result~~

Supply Chain and Capital Expenditures

SPS’ ability to meet customer energy requirements, respond to storm-related disruptions and execute our capital expenditure program are dependent on maintaining an efficient supply chain. Overall, as a result of COVID-19, manufacturing processes have experienced disruptions related to scarcity of raw materials and interruptions in production and shipping. These disruptions have been further exacerbated by inflationary pressures, storms and labor shortages. The Company continues to monitor the availability of materials and seek alternative suppliers as necessary.

~~Table of Contents~~


Public Utility Regulation

The FERC and state and local regulatory commissions regulate SPS. SPS is subject to rate regulation by state utility regulatory agencies, which have jurisdiction with respect to the rates of electric distribution companies in New Mexico and Texas.

Rates are designed to recover plant investment, operating costs and an allowed return on investment. SPS requests changes in utility rates through commission filings. Changes in operating costs can affect SPS’ financial results, depending on the timing of rate case filings and implementation of final rates. Other factors affecting rate filings are new investments, sales, conservation and DSM efforts, and the cost of capital.

In addition, the regulatory commissions authorize the ROE, capital structure and depreciation rates in rate proceedings. Decisions by these regulators can significantly impact SPS’ results of operations.

Except to the extent noted below, the circumstances set forth in Public Utility Regulation included in Item 7 of SPS’ Annual Report on Form 10-K for the year ended Dec. 31, 2020 and in Item 2 of SPS’ Quarterly Report on F o rm 10-Q for the quarterly period ended March 31, 2021, appropriately represent, in all material respects, the current status of public utility regulation and are incorporated herein by reference.

Additional Information:

2021 New Mexico Electric Rate Case — In January 2021, SPS filed an electric rate case with the NMPRC seeking an increase in base rates of approximately $88 million. SPS' net rate increase to New Mexico customers is expected to be approximately $48 million, or 10%, as a result of the offsetting fuel cost reductions and PTCs from the Sagamore wind project. PTCs are ~~being~~ credited to customers through the fuel clause. In June 2021, SPS revised its requested base rate increase to $84 million.

The request iswas based on a historic test year ended Sept. 30, 2020, including expected capital additions through Feb. 28, 2021, a ROE of 10.35%, an equity ratio of 54.72% and a retail rate base of approximately $1.9 billion.

~~The request~~In June 2021, SPS and various parties filed an uncontested comprehensive stipulation, which includes:

•Base rate revenue increase of $62 million.

•ROE of 9.35% for purposes of filings related to (1) the Hale and Sagamore wind projects; and (2) reconciliation of the settlement revenue requirement.

•Equity ratio of 54.72%.

•Increase in depreciation expense of $6 million. This includes a change in the ~~effect of approximately 400 MW of reduced peak load in 2021 from a wholesale transmission customer and changes to depreciation~~depreciable lives of ~~SPS’~~the Tolk ~~coal-fired~~ power plant ~~(from 2037~~ to ~~2032)~~2032 and ~~the~~ coal handling assets at the Harrington facility ~~(to 2024).~~

~~The procedural schedule is expected~~ to ~~be as follows:~~

•~~Staff and intervenor testimony — May 17, 2021.~~2024.

•~~Rebuttal testimony — June 9, 2021.~~

•~~Deadline to file stipulation — June 23, 2021.~~

•~~Public~~A public hearing ~~or hearing on stipulation —~~is scheduled for July 26 - Aug. 6, 2021.

•~~End of nine month suspension — Nov. 3, 2021.~~

A NMPRC decision and implementation of final rates is anticipated in the fourth quarter of 2021.

2021 Texas Electric Rate Case — In February 2021, SPS filed an electric rate case with the PUCT and its municipalities ~~with original rate jurisdiction~~ seeking an increase in base rates of approximately $143 million. SPS' net rate increase to Texas customers is expected to be approximately $74 million, or 9.2%, as a result of the offsetting $69 million in fuel cost reductions and PTCs from the Sagamore wind project.

The request is based on ana ROE of 10.35%, an equity ratio of 54.60% ~~(based on actual capital structure)~~, a ~~Texas retail~~ rate base of approximately $3.3 billion and a historic test year based on the 12-month period ended Dec. 31, 2020.

The request includes the effect of losing approximately 400 MW from a wholesale transmission customer and changes to depreciation lives of SPS’ Tolk power plant (from 2037 to 2032) and ~~the~~ coal handling assets ofat the Harrington facility (to 2024).

~~The procedural~~Procedural schedule is expected to be as follows:

•Intervenor testimony — Aug. 13, 2021.

•Staff testimony — Aug. 20, 2021.

•Rebuttal testimony — Sept. 15, 2021.

•Public hearing — Oct. 18 - Oct. 28, 2021.

The PUCT set current rates as temporary as of March 15, 2021. Once final rates are approved, a surcharge will be requested from March 15, 2021 through the effective date of new base rates. A PUCT decision is expected in the first quarter of 2022.

~~Texas State ROFR Litigation —~~ In May 2019, the Governor signed a ROFR bill into law, which grants incumbent utilities a ROFR to build transmission infrastructure when it directly interconnects to the utility’s existing facility. In June 2019, a complaint was filed in the United States District Court for the Western District of Texas claiming the new ROFR law to be unconstitutional. In February 2020, the federal court complaint was dismissed by the district court. In March 2020, the district court ruling was appealed to the Fifth Circuit. A decision is pending.

New Mexico ~~FPPCAC Continuation~~Integrated Resource Plan — In ~~December 2020, the Hearing Examiner recommended~~July 2021, SPS filed an IRP with the NMPRC, ~~approve SPS’ request for~~as required every three years. SPS is forecasting sufficient resources through 2025. A projected capacity deficit was identified totaling approximately 174 MW in 2031, increasing to 4,194 MW by 2041.

Table of Contents

SPS has provided a number of alternatives, including a proposed portfolio of resources incorporating the ~~continued use~~addition of ~~the FPPCAC~~wind generation, solar generation, firm and the reconciliation of its fuel costs for the reporting period (September 2015 through June 2019). Additionally, the Hearing Examiner recommended the NMPRC deny the proposed Annual Deferred Fuel Balance True-Up. The proposed true-up is designed to maintain the Deferred Fuel and Purchased Power balance within a bandwidth of plus or minus 5% of annual New Mexico fueldispatchable peaking generation, and purchased power ~~costs. In February 2021,~~agreements. SPS will continue to evaluate other options including energy storage and emerging technologies, taking into consideration cost-effectiveness. The IRP is subject to public comment and potential public hearings and will ultimately be reviewed by the NMPRC ~~approved the Hearing Examiner’s recommended decision without modification.~~for approval.

Environmental

~~Environmental Regulation~~Affordable Clean Energy

In July 2019, the EPA adopted the Affordable Clean Energy rule, which requires states to develop plans by 2022 for greenhouse gas reductions from coal-fired power plants. In January 2021, the U.S. Court of Appeals for the D.C. Circuit issued a decision vacating and remanding the Affordable Clean Energy rule. That decision, if not successfully appealed or reconsidered, would allow the EPA to proceed with alternate regulation of coal-fired power plants. If the new rules require additional investment, SPS believes, based on prior state commission practices, that the cost of these initiatives or replacement generation would be recoverable through rates.

Emerging Regulation

New regulations and legislation are being considered to regulate PFAS in drinking water, water discharges, commercial products, wastes, and other areas. PFAS are man-made chemicals found in many consumer products that can persist and accumulate in the environment. These chemicals have received heightened attention by environmental regulators. Increased regulation of PFAS and other emerging contaminants at the federal, state, and local level could have a potential adverse effect on our operations but at this time, it is uncertain what impact, if any, there will be on our results of operations, financial condition or cash flows. SPS will continue to monitor these regulatory developments and their potential impact on its operations


ITEM 4 — CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

SPS maintains a set of disclosure controls and procedures designed to ensure that information required to be disclosed in reports that it files or submits under the Securities Exchange Act of 1934 is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms.

~~Table of Contents~~

In addition, the disclosure controls and procedures ensure that information required to be disclosed is accumulated and communicated to management, including the CEO and CFO, allowing timely decisions regarding required disclosure.

As of ~~March 31,~~June 30, 2021, based on an evaluation carried out under the supervision and with the participation of SPS’ management, including the CEO and CFO, of the effectiveness of its disclosure controls and procedures, the CEO and CFO have concluded that SPS’ disclosure controls and procedures were effective.

Internal Control Over Financial Reporting

No changes in SPS’ internal control over financial reporting occurred during the most recent fiscal quarter that materially affected, or are reasonably likely to materially affect, SPS’ internal control over financial reporting.

PART II — OTHER INFORMATION


ITEM 1 — LEGAL PROCEEDINGS

Management is sometimes unable to estimate an amount or range of a reasonably possible loss in certain situations, including but not limited to, when (1) the damages sought are indeterminate, (2) the proceedings are in the early stages or (3) the matters involve novel or unsettled legal theories. In such cases, there is considerable uncertainty regarding the timing or ultimate resolution of such matters, including a possible eventual loss.

See Note 9 to the financial statements and Part I Item 2 for further information.


ITEM 1A — RISK FACTORS

SPS’ risk factors are documented in Item 1A of Part I of its Annual Report on Form 10-K for the year ended Dec. 31, 2020, which is incorporated herein by reference. There have been no material changes from the risk factors previously disclosed in the Form 10-K.
