2020 YEAR END EARNINGS REPORT

•2020 earnings per share were $2.79 compared with $2.64 per share in 2019.

•Xcel Energy reaffirms 2021 EPS earnings guidance of $2.90 to $3.00 per share.

MINNEAPOLIS — Xcel Energy Inc. (NASDAQ: XEL) today reported 2020 GAAP and ongoing earnings of $1.47 billion, or $2.79 per share, compared with $1.37 billion, or $2.64 per share in the same period in 2019.

“Xcel Energy had a strong year despite the challenges brought on by COVID-19,” said Ben Fowke, chairman and CEO. “We achieved major milestones while keeping our employees and customers safe and are well positioned for the coming year and beyond.”

“I’m proud of the support we provided our communities, committing nearly $20 million to short and long-term corporate giving. Our $750 million plan to repower several wind farms in Minnesota was approved, which is expected to result in substantial customer savings and jobs creation. In Colorado, we received approval for an electric vehicle plan and are excited about the related opportunities. We also announced the early retirement of the Hayden and Craig coal plants and plans to convert our Harrington facility to natural gas. These achievements move us closer to achieving our goals of an 80% carbon reduction by 2030 and delivering 100% carbon-free electricity by 2050.”

XCEL ENERGY INC. AND SUBSIDIARIES

Notes to Investor Relations Earnings Release (Unaudited)

Due to the seasonality of Xcel Energy’s operating results, quarterly financial results are not an appropriate base from which to project annual results.

Non-GAAP Financial Measures

The following discussion includes financial information prepared in accordance with generally accepted accounting principles (GAAP), as well as certain non-GAAP financial measures such as ongoing return on equity (ROE), electric margin, natural gas margin, ongoing earnings and ongoing diluted EPS. 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. Xcel Energy’s 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.

Ongoing ROE

Ongoing ROE is calculated by dividing the net income or loss of Xcel Energy or each subsidiary, adjusted for certain

nonrecurring items, by each entity’s average stockholder’s equity.

Electric and Natural Gas Margins

Electric margin is presented as electric revenues less electric fuel and purchased power expenses. Natural gas margin is presented as natural gas revenues less the cost of natural gas sold and transported. Expenses incurred for electric fuel and purchased power and the cost of natural gas are generally recovered through various regulatory recovery mechanisms. As a result, changes in these expenses are generally offset in operating revenues. Management believes electric and natural gas 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, cost of sales - other, operating and maintenance (O&M) expenses, conservation and demand side management (DSM) expenses, depreciation and amortization and taxes (other than income taxes).

Earnings Adjusted for Certain Items (Ongoing Earnings and Ongoing Diluted EPS)

GAAP diluted EPS reflects the potential dilution that could occur if securities or other agreements to issue common stock (i.e., common stock equivalents) were settled. The weighted average number of potentially dilutive shares outstanding used to calculate Xcel Energy Inc.’s diluted EPS is calculated using the treasury stock method. Ongoing earnings reflect adjustments to GAAP earnings (net income) for certain items. Ongoing diluted EPS is calculated by dividing the net income or loss of each subsidiary, adjusted for certain items, by the weighted average fully diluted Xcel Energy Inc. common shares outstanding for the period. Ongoing diluted EPS for each subsidiary is calculated by dividing the net income or loss of such subsidiary, adjusted for certain items, by the weighted average fully diluted Xcel Energy Inc. common shares outstanding for the period.

We use these non-GAAP financial measures to evaluate and provide details of Xcel Energy’s core earnings and underlying performance. We believe these measurements are useful to investors to evaluate the actual and projected financial performance and contribution of our subsidiaries. For the three and twelve months ended Dec. 31, 2020 and 2019, there were no such adjustments to GAAP earnings and therefore GAAP earnings equal ongoing earnings for these periods.

Note 1. Earnings Per Share Summary

Xcel Energy’s 2020 earnings were $2.79 per share compared to $2.64 per share in 2019, primarily reflecting higher electric margin (largely due to regulatory outcomes which recover capital investment), higher allowance for funds used during construction (AFUDC) and lower O&M expenses, which offset increased depreciation, interest expense and declining sales primarily due to the impacts of COVID-19.

Summarized diluted EPS for Xcel Energy:

	Three Months Ended Dec. 31				Twelve Months Ended Dec. 31
Diluted Earnings (Loss) Per Share	2020		2019		2020		2019
NSP-Minnesota	$	0.23	$	0.24	$	1.12	$	1.04
PSCo	0.25		0.25		1.11		1.11
SPS	0.10		0.09		0.56		0.51
NSP-Wisconsin	0.04		0.03		0.20		0.15
Equity earnings of unconsolidated subsidiaries	0.01		0.01		0.05		0.05

Total (a)	$	0.54	$	0.56	$	2.79	$	2.64

(a) Amounts may not add due to rounding.

NSP-Minnesota — Earnings increased $0.08 per share for 2020, reflecting higher electric margin (riders, wholesale transmission revenue and a sales true-up mechanism, which recovers lower sales due to COVID-19) and lower O&M expenses, partially offset by increased depreciation and lower natural gas margin.

PSCo — Earnings were flat for 2020, reflecting higher electric margin (wholesale transmission revenue and regulatory outcomes offset lower sales due to COVID-19), increased AFUDC and higher natural gas margin, offset by additional depreciation and taxes (other than income taxes).

SPS — Earnings increased $0.05 per share for 2020, reflecting higher electric margin (wholesale transmission revenue and regulatory outcomes offset lower sales due to COVID-19) and lower O&M expenses, partially offset by increased depreciation, interest expense and taxes (other than income taxes).

NSP-Wisconsin — Earnings increased $0.05 per share for 2020, reflecting higher electric margin (regulatory outcomes offset lower sales due to COVID-19) and lower O&M expenses, partially offset by increased depreciation and lower natural gas margin.

Xcel Energy Inc. and Other — Primarily includes financing costs at the holding company.

Note 2. Regulated Utility Results

Estimated Impact of Temperature Changes on Regulated Earnings — Unusually hot summers or cold winters increase electric and natural gas sales, while mild weather reduces electric and natural gas sales. The estimated impact of weather on earnings is based on the number of customers, temperature variances, the amount of natural gas or electricity historically used per degree of temperature and excludes any incremental related operating expenses that could result due to storm activity or vegetation management requirements. As a result, weather deviations from normal levels can affect Xcel Energy’s financial performance to the extent there is not a decoupling or sales true-up mechanism in the state.

Degree-day or Temperature-Humidity Index (THI) data is used to estimate amounts of energy required to maintain comfortable indoor temperature levels based on each day’s average temperature and humidity. Heating degree-days (HDD) is the measure of the variation in the weather based on the extent to which the average daily temperature falls below 65° Fahrenheit. Cooling degree-days (CDD) is the measure of the variation in the weather based on the extent to which the average daily temperature rises above 65° Fahrenheit. Each degree of temperature above 65° Fahrenheit is counted as one CDD, and each degree of temperature below 65° Fahrenheit is counted as one HDD. In Xcel Energy’s more humid service territories, a THI is used in place of CDD, which adds a humidity factor to CDD. HDD, CDD and THI are most likely to impact the usage of Xcel Energy’s residential and commercial customers. Industrial customers are less sensitive to weather.

6

Normal weather conditions are defined as either the 10, 20 or 30-year average of actual historical weather conditions. The historical period of time used in the calculation of normal weather differs by jurisdiction, based on regulatory practice. To calculate the impact of weather on demand, a demand factor is applied to the weather impact on sales. Extreme weather variations, windchill and cloud cover may not be reflected in weather-normalized estimates.

(a) Higher residential sales and lower commercial and industrial (C&I) sales were primarily attributable to COVID-19. The increase in residential sales was partially driven by more customers working from home.

Weather-normalized and leap-year adjusted electric sales growth (decline) — year-to-date (excluding leap day)

•PSCo — Residential sales rose based on an increased number of customers and higher use per customer. The decline in C&I sales was primarily due to COVID-19, particularly within the manufacturing and service industries, partially offset by an increase in the energy sector.

•NSP-Minnesota — Residential sales rose based on an increased number of customers and higher use per customer. The decline in C&I sales was primarily due to COVID-19, particularly within the energy, manufacturing and services sectors.

•SPS — Residential sales rose based on an increased number of customers and higher use per customer. The decline in C&I sales was primarily due to COVID-19, particularly within the energy and manufacturing sectors.

•NSP-Wisconsin — Residential sales rose based on an increased number of customers and higher use per customer. The decline in C&I sales was primarily due to COVID-19, particularly within the energy and manufacturing sectors.

Weather-normalized and leap-year adjusted natural gas sales growth (decline) — year-to-date (excluding leap day)

•Higher natural gas sales reflect an increase in the number of customers combined with higher residential customer use, partially offset by lower C&I customer use.

Electric Margin — Electric revenues and fuel and purchased power expenses are impacted by fluctuations in the price of natural gas, coal and uranium. However, these fluctuations have minimal impact on margin due to fuel recovery mechanisms. In addition, electric customers receive a credit for PTCs generated, which reduce electric revenue and margin (offset by lower tax expense).

Natural Gas Margin — Natural gas expense varies with changing sales and cost of natural gas. However, fluctuations in the cost of natural gas has minimal impact on margin due to cost recovery mechanisms.

Natural gas revenues and margin:

	Three Months Ended Dec. 31				Twelve Months Ended Dec. 31
(Millions of Dollars)	2020		2019		2020		2019
Natural gas revenues	$	554	$	544	$	1,636	$	1,868

Total increase (decrease) in natural gas margin	$	18	$	(3)

O&M Expenses — O&M expenses decreased $14 million, or 0.6%, for 2020, largely reflecting management actions to reduce costs to offset the impact of lower sales from COVID-19. Significant changes are as follows:

(Millions of Dollars)	Three Months Ended Dec. 31, 2020 vs. 2019		Twelve Months Ended Dec. 31, 2020 vs. 2019
Distribution	$	(7)	$	(47)

Employee benefits	11		12
Texas rate case deferral	3		8
Other (net)	8		3
Total increase (decrease) in O&M expenses	$	42	$	(14)

•Distribution declined due to cost mitigation/continuous improvement efforts and timing of maintenance, partially offset by increased storm impacts.

•Generation was lower from timing of maintenance and overhauls at power plants and cost mitigation/continuous improvement efforts, partially offset by an increase in maintenance expenses from wind expansion.

•Transmission declined due to cost mitigation/continuous improvement initiatives.

•Minnesota payment plan credit program represents a commitment to fund customer programs as agreed to in the NSP-Minnesota rate case stay-out.

•Information technology costs increased due to higher spending on network and other infrastructure costs.

•Employee benefits increased due primarily to postretirement costs and other long-term benefits, partially offset by lower deferred compensation expense.

Depreciation and Amortization — Depreciation and amortization increased $183 million, or 10.4%, year-to-date. The increase was primarily driven by the Hale, Cheyenne Ridge, Foxtail, Blazing Star I, Lake Benton, Sagamore, Crowned Ridge, Community Wind North and Jeffers wind facilities going into service, as well as normal system expansion. In addition, new depreciation rates were implemented in Colorado, New Mexico and Texas in 2020, increasing expense.

Taxes (Other than Income Taxes) — Taxes (other than income taxes) increased $43 million, or 7.6%, year-to-date. The increase was primarily due to higher property taxes in Colorado and Texas (net of deferred amounts).

Other Income (Expense) — Other income (expense) decreased $22 million year-to-date. The decrease was largely due to the performance of rabbi trust investments, primarily offset in O&M expenses.

9

AFUDC, Equity and Debt — AFUDC increased $43 million year-to-date. The increase was primarily due to various wind projects under construction.

Interest Charges — Interest charges increased $67 million, or 8.7%, year-to-date. The increase was largely due to higher debt levels to fund capital investments, partially offset by lower long-term and short-term interest rates.

Income Taxes — Effective income tax rate:

	Three Months Ended Dec. 31						Twelve Months Ended Dec. 31
	2020		2019		2020 vs 2019		2020		2019		2020 vs 2019

Other (net)	0.8		(0.4)		1.2		(0.9)		(0.5)		(0.4)
Effective income tax rate	(11.6)	%	2.3	%	(13.9)	%	(0.4)	%	8.5	%	(8.9)	%

(a) Regulatory differences for income tax primarily relate to the credit of excess deferred taxes to customers. Income tax benefits associated with this credit are generally offset by corresponding revenue reductions.

Income taxes decreased $37 million for the fourth quarter. The decrease was primarily driven by an increase in wind PTCs and lower pretax earnings. Wind PTCs are credited to customers (recorded as a reduction to revenue) and do not have a material impact on net income.

Income taxes decreased $134 million year-to-date. The decrease was primarily driven by an increase in wind PTCs and an increase in plant-related regulatory differences.

Note 4. Rates and Regulation

Minnesota Relief and Recovery— In 2020, the Minnesota Public Utilities Commission (MPUC) opened a docket and invited utilities in the state to submit potential projects that would create jobs and help jump start the economy to offset the impacts of COVID-19. NSP-Minnesota’s proposal included the following:

•Repower 651 MW of owned wind projects (capital investment of $750 million) as well as certain wind projects under PPAs.

•Acquire 120 MW repowered wind farm and buy-out of an existing PPA for $210 million.

•Add solar facilities of 460 MW with an incremental investment of $550 million.

•Accelerate certain grid investment.

•Provide $150 million of incremental electric vehicle (EV) rebates.

In December 2020, The MPUC verbally approved the repowering of owned wind projects and 20 MW of wind projects under PPAs. These projects are estimated to save customers approximately $160 million over the next 25 years. The MPUC is expected to address the solar, the PPA wind repowering acquisition and the EV proposal in the second half of 2021.

NSP-Minnesota 2020 Electric Rate Case — In November 2020, NSP-Minnesota filed an electric rate case seeking a $597 million revenue increase over three years with the MPUC. The rate case is based on a requested ROE of 10.2% and a 52.5% equity ratio. NSP-Minnesota also filed a stay-out alternative in which it would withdraw its rate case filing.

In December 2020, the MPUC verbally approved the stay-out alternative petition, which includes the extension of the sales, capital and property tax true-up mechanisms and delays any increase to the Nuclear Decommissioning Trust annual accrual until Jan. 1, 2022.

Additionally, NSP-Minnesota agreed to not seek recovery of incremental COVID-19 related bad debt expense and committed to fund $17.5 million in a Residential Payment Plan Credit Program or other similar customer relief programs, as directed by the MPUC. NSP-Minnesota also agreed to an earnings test in which all earnings above an ROE of 9.06% in 2021 would be refunded to customers.

2020 North Dakota Electric Rate Case — In November 2020, NSP-Minnesota filed a request with the North Dakota Public Service Commission for an overall increase in annual retail electric revenues of approximately $22 million, or an increase of 10.8%. The request is driven by ongoing investments in carbon-free electrical generation, distribution and transmission infrastructure. The rate filing is based on a 2021 forecast test year and includes a requested ROE of 10.2%, electric rate base of approximately $677 million and an equity ratio of 52.50%. In addition, interim rates, subject to refund, of approximately $16 million were implemented on Jan. 5, 2021.

PSCo 2020 Natural Gas Rate Case — In October 2020, the CPUC approved a comprehensive settlement, resulting in a net rate increase of $77 million. This increase reflects a $94 million increase in base rate revenue, partially offset by $17 million of costs previously recovered through the Pipeline Integrity rider. Rates will be implemented on April 1, 2021 (retroactive to November 2020).

PSCo Wildfire Protection Rider —In 2020, PSCo requested to establish a rider to recover incremental costs associated with system investments to reduce wildfire risk. The rider would be effective in June 2021 and continue through 2025. The Office of Consumer Counsel and CPUC Staff are supportive of the wildfire mitigation program, but oppose rider recovery and instead recommend deferral of certain costs with recovery in a future rate case. A CPUC decision is expected in the second quarter of 2021.

Wildfire Protection capital investment is projected to be approximately $325 million. Forecasted annual revenue requirements from 2021 through 2025:

(Millions of Dollars)	2021		2022		2023		2024		2025
Forecasted annual revenue requirements	$	17	$	24	$	29	$	32	$	34

PSCo Transportation Electrification Plan (TEP) — In January 2021, the CPUC approved PSCo's TEP, which authorizes rider recovery of new electric vehicle utility programs for the residential, commercial, multi-family and public charging sectors. The approval establishes utility-owned charging infrastructure and chargers and amortization of rebates for electric vehicles. The TEP approval authorizes approximately $110 million in spending with flexibility up to approximately $138 million over three years.

13

SPS — New Mexico 2021 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 offsetting fuel cost reductions and PTCs attributable to the Sagamore wind project. A NMPRC decision and implementation of final rates is anticipated in the fourth quarter of 2021.

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

In addition, the request includes the reduction of approximately 400 MW wholesale peak load in 2021 and changes to depreciation lives of SPS’ Tolk coal-fired power plant (from 2037 to 2032) and the coal handling assets at the Harrington facility (to 2024).

SPS’ base rate request:

(Millions of Dollars)
Sagamore wind project investment	$	38
Other plant investment	40
Allocator changes due to load growth	9
Depreciation rate change (including Tolk)	3
Other, net	(2)
Total rate request	88
Fuel cost reductions and PTCs	(40)
Net rate increase	$	48

Note 5. Coal Plant Closures

Xcel Energy has a goal to reduce carbon emissions 80% by 2030 (over 2005 levels) and ultimately deliver 100% carbon-free electricity to customers by 2050. The following actions were recently announced to support these initiatives:

•A proposal to close the Hayden coal plant in Colorado, retiring Unit 2 by the end of 2027 and Unit 1 in 2028 (totaling 233 MW of capacity for Xcel Energy). Further details on the early closure will be included in an electric resource plan to be filed with the CPUC in March 2021.

•Retire the Craig generating station in Colorado, with Unit 1 closing in 2025 and Unit 2 closing in 2028 (totaling 82 MW of capacity for Xcel Energy).

•Convert the Harrington generating station in Texas (three units with 1,018 MW of capacity) to natural gas by Jan. 1, 2025.

Note 6. Earnings Guidance and Long-Term EPS and Dividend Growth Rate Objectives

Xcel Energy 2021 Earnings Guidance — Xcel Energy’s 2021 GAAP and ongoing earnings guidance is a range of $2.90 to $3.00 per share.(a)

Key assumptions as compared with 2020 levels unless noted:

•Constructive outcomes in all rate case and regulatory proceedings.

•Modest impacts from COVID-19.

•Normal weather patterns for the remainder of the year.

•Weather-normalized retail electric sales are projected to increase ~1%.

•Weather-normalized retail firm natural gas sales are projected to be relatively flat.

•Capital rider revenue is projected to increase $105 million to $115 million (net of PTCs). The change reflects the deferral of advanced grid costs, which were denied rider recovery. PTCs are credited to customers, through capital riders, fuel clause or base rates and results in a reduction to electric margin.

•O&M expenses are projected to be relatively flat.

•Depreciation expense is projected to increase approximately $195 million to $205 million.

•Property taxes are projected to increase approximately $45 million to $55 million.

•Interest expense (net of AFUDC - debt) is projected to increase $0 million to $10 million.

•AFUDC - equity is projected to decline approximately $45 million to $55 million.

•ETR is projected to be ~(9%). The ETR reflects benefits of PTCs which are credited to customers through electric margin and will not have a material impact on net income.

(a)     Ongoing earnings is calculated using net income and adjusting for certain nonrecurring or infrequent items that are, in management’s view, not reflective of ongoing operations. Ongoing earnings could differ from those prepared in accordance with GAAP for unplanned and/or unknown adjustments. Xcel Energy is unable to forecast if any of these items will occur or provide a quantitative reconciliation of the guidance for ongoing EPS to corresponding GAAP EPS.

Long-Term EPS and Dividend Growth Rate Objectives —Xcel Energy expects to deliver an attractive total return to our shareholders through a combination of earnings growth and dividend yield, based on the following long-term objectives:

•     Deliver long-term annual EPS growth of 5% to 7% based off of a 2020 base of $2.78 per share, which represents the mid-point of the original 2020 guidance range of $2.73 to $2.83 per share.

•    Deliver annual dividend increases of 5% to 7%.

•     Target a dividend payout ratio of 60% to 70%.

•     Maintain senior secured debt credit ratings in the A range.
