FORWARD-LOOKING INFORMATION
This Quarterly Report on Form 10-Q includes “forward-looking statements” as defined by the SEC. Forward-looking statements are all statements other than statements of historical fact, including without limitation those statements that are identified by the words “anticipates,” “estimates,” “expects,” “intends,” “plans,” “predicts” and similar expressions, and include statements concerning plans, objectives, goals, strategies, future events or performance, and underlying assumptions and other statements that are other than statements of historical facts. We make these forward-looking statements in reliance on the safe harbor protections provided under the Private Securities Litigation Reform Act of 1995. These forward-looking statements are based on assumptions which we believe are reasonable based on current expectations and projections about future events and industry conditions and trends affecting our business. However, whether actual results and developments will conform to our expectations and predictions is subject to a number of risks and uncertainties that, among other things, could cause actual results to differ materially from those contained in the forward-looking statements, including without limitation, the risk factors described in Item 1A of Part I of our 2021 Annual Report on Form 10-K, Part II, Item 1A of this Quarterly Report on Form 10-Q and other reports that we file with the SEC from time to time, and the following:
•Our ability to obtain adequate cost recovery for our utility operations through regulatory proceedings and favorable rulings on periodic applications to recover costs for capital additions, plant retirements and decommissioning, fuel, transmission, purchased power, and other operating costs and the timing in which new rates would go into effect;
•Our ability to complete our capital program in a cost-effective and timely manner;
•Our ability to execute on our strategy;
•Our ability to successfully execute our financing plans;
•Our ability to achieve our greenhouse gas emissions intensity reduction goals;
•Board of Directors’ approval of any future quarterly dividends;
•The impact of future governmental regulation;
•Our ability to overcome the impacts of supply chain disruptions on availability and cost of materials;
•The effects of inflation and volatile energy prices; and
•Other factors discussed from time to time in our filings with the SEC.
New factors that could cause actual results to differ materially from those described in forward-looking statements emerge from time-to-time, and it is not possible for us to predict all such factors, or the extent to which any such factor or combination of factors may cause actual results to differ from those contained in any forward-looking statement. We assume no obligation to update publicly any such forward-looking statements, whether as a result of new information, future events or otherwise.

Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to such rules and regulations; however, we believe that the footnotes adequately disclose the information presented. These Condensed Consolidated Financial Statements should be read in conjunction with the consolidated financial statements and the notes included in our 2021 Annual Report on Form 10-K.
Segment Reporting
Our reportable segments are based on our method of internal reporting, which is generally segregated by differences in products and services. All of our operations and assets are located within the United States. We conduct our operations through the Electric Utilities and Gas Utilities segments. In the fourth quarter of 2021, we integrated our power generation and mining businesses within the Electric Utilities segment. The alignment is consistent with the current way our CODM evaluates the performance of the business and makes decisions related to the allocation of resources. Comparative periods presented reflect this change.
For further information regarding our segment reporting, see Note 12.
Use of Estimates and Basis of Presentation
The information furnished in the accompanying Condensed Consolidated Financial Statements reflects certain estimates required and all adjustments, including accruals, which are, in the opinion of management, necessary for a fair presentation of the March 31, 2022, December 31, 2021 and March 31, 2021 financial information. Certain lines of business in which we operate are highly seasonal, and our interim results of operations are not necessarily indicative of the results of operations to be expected for an entire year.
Recently Issued Accounting Standards
Facilitation of the Effects of Reference Rate Reform on Financial Reporting, ASU 2020-04
In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which was subsequently amended by ASU 2021-01. The standard provides relief for companies preparing for discontinuation of interest rates, such as LIBOR, and allows optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. The amendments in this update are elective and are effective upon the ASU issuance through December 31, 2022. We are currently evaluating whether we will apply the optional guidance as we assess the impact of the discontinuance of LIBOR on our current arrangements but do not expect it to have a material impact on our financial position, results of operations and cash flows.

__________
(a) Timing of Winter Storm Uri incremental cost recovery and associated carrying costs vary by jurisdiction and some jurisdictions are still subject to pending applications with the respective utility commission. See further information below.
(b) Recovery of costs, but we are not allowed a rate of return.
(c) In addition to recovery or repayment of costs, we are allowed a return on a portion of this amount or a reduction in rate base.
Regulatory Activity
Except as discussed below, there have been no other significant changes to our Regulatory Matters from those previously disclosed in Note 2 of the Notes to the Consolidated Financial Statements in our 2021 Annual Report on Form 10-K.
Winter Storm Uri
In February 2021, a prolonged period of historic cold temperatures across the central United States, which covered all of our Utilities’ service territories, caused a substantial increase in heating and energy demand and contributed to unforeseeable and unprecedented market prices for natural gas and electricity. As a result of Winter Storm Uri, we incurred significant incremental fuel, purchased power and natural gas costs.
Our Utilities submitted Winter Storm Uri cost recovery applications in our state jurisdictions seeking to recover $546 million of these incremental costs through separate tracking mechanisms over a weighted-average recovery period of 3.5 years. These incremental cost estimates are subject to adjustments as final decisions are issued by the respective utility commissions. In these applications, we seek approval to recover carrying costs. For the three months ended March 31, 2022 and 2021, $2.3 million and $0, respectively, of carrying costs were accrued and recorded to a regulatory asset.

Table of Contents
On January 27, 2022, Kansas Gas received approval from the KCC for their Winter Storm Uri cost recovery settlement with final rates implemented in February 2022. In March 2022, Colorado Electric and Colorado Gas received approval from the CPUC for their respective Winter Storm Uri cost recovery settlements with final rates implemented in April 2022.
To date, Colorado Electric, Colorado Gas, Iowa Gas, Kansas Gas, Nebraska Gas and South Dakota Electric received commission approval of their Winter Storm Uri cost recovery applications. Additionally, Arkansas Gas and Wyoming Gas received approval for interim cost recovery subject to a final decision on carrying costs and recovery periods at a later date. For the three months ended March 31, 2022, our Utilities collected $73 million of Winter Storm Uri incremental costs and carrying costs from customers. As of March 31, 2022, we estimate that our remaining Winter Storm Uri regulatory asset has a weighted-average recovery period of 3.1 years.
TCJA
As part of Kansas Gas’s 2021 rate review settlement agreement, Kansas Gas will deliver $3.0 million of TCJA and state tax reform benefits to customers, annually, for three years starting in 2022 (approximately $9.1 million of total benefits expected to be delivered). For the three months ended March 31, 2022, Kansas Gas delivered $0.8 million of TCJA-related bill credits to customers.
These bill credits, which resulted in a reduction of revenue, were offset by a reduction in income tax expense and resulted in a minimal impact to Net income for the three months ended March 31, 2022.
Arkansas Gas
On December 10, 2021, Arkansas Gas filed a rate review with the APSC seeking recovery of significant infrastructure investments in its 7,200-mile natural gas pipeline system. The rate review requests $22 million in new annual revenue with a capital structure of 50.9% equity and 49.1% debt and a return on equity of 10.2%. The request seeks to finalize rates in the fourth quarter of 2022.
(3) Commitments, Contingencies and Guarantees
There have been no significant changes to commitments, contingencies and guarantees from those previously disclosed in Note 3 of our Notes to the Consolidated Financial Statements in our 2021 Annual Report on Form 10-K except for those described below.
Power Sales Agreement
On May 3, 2022, South Dakota Electric entered into an agreement with MDU to provide MDU capacity and energy up to a maximum of 50 MW in excess of Wygen III ownership. This agreement, which has similar terms and conditions as South Dakota Electric’s existing agreement with MDU expiring on December 31, 2023, is effective on January 1, 2024 and will expire on December 31, 2028.
GT Resources, LLC v. Black Hills Corporation, Case No. 2020CV30751 (U.S. District Court for the City and County of Denver, Colorado)
On April 13, 2022, a jury awarded $41 million for claims made by GT Resources, LLC (“GTR”) against BHC and two of its subsidiaries (Black Hills Exploration and Production, Inc. and Black Hills Gas Resources, Inc.), which ceased oil and natural gas operations in 2018 as part of BHC’s decision to exit the exploration and production business. The claims involved a dispute over a 2.3 million-acre concession award in Costa Rica which was acquired by a BHC subsidiary in 2003. GTR retained rights to receive a royalty interest on any hydrocarbon production from the concession upon the occurrence of contingent events. GTR contended that BHC and its subsidiaries failed to adequately pursue the opportunity and failed to transfer the concession to GTR. We believe we have meritorious defenses to the verdict and intend to appeal the verdict. At this time, we believe that the liability related to this matter, if any, is not reasonably estimable.
Power Purchase Agreement
On February 19, 2021, Colorado Electric entered into an agreement with TC Colorado Solar, LLC (TC Solar) to purchase up to 200 MW of renewable energy upon construction of a new solar facility, to be owned by TC Solar. This agreement relates to a new solar facility to be constructed and would expire 15 years after construction completion. On January 31, 2022, TC Solar provided notice of its intent to terminate the PPA. We disputed TC Solar's right to termination and, pursuant to the agreement, entered resolution negotiations to amend certain contract terms with TC Solar, which are ongoing.

(7) Risk Management and Derivatives
Market and Credit Risk Disclosures
Our activities in the energy industry expose us to a number of risks in the normal operations of our businesses. Depending on the activity, we are exposed to varying degrees of market risk and credit risk.
Market Risk
Market risk is the potential loss that may occur as a result of an adverse change in market price, rate or supply. We are exposed but not limited to, the following market risks:
•Commodity price risk associated with our retail natural gas and wholesale electric power marketing activities and our fuel procurement for several of our gas-fired generation assets, which include market fluctuations due to unpredictable factors such as the COVID-19 pandemic, weather (Winter Storm Uri), market speculation, inflation, pipeline constraints, and other factors that may impact natural gas and electric supply and demand; and
•Interest rate risk associated with future debt, including reduced access to liquidity during periods of extreme capital markets volatility, such as the 2008 financial crisis and the COVID-19 pandemic.
Credit Risk
Credit risk is the risk of financial loss resulting from non-performance of contractual obligations by a counterparty.
We attempt to mitigate our credit exposure by conducting business primarily with high credit quality entities, setting tenor and credit limits commensurate with counterparty financial strength, obtaining master netting agreements and mitigating credit exposure with less creditworthy counterparties through parental guarantees, cash collateral requirements, letters of credit and other security agreements.
18

Table of Contents
We perform ongoing credit evaluations of our customers and adjust credit limits based upon payment history and the customers’ current creditworthiness, as determined by review of their current credit information. We maintain a provision for estimated credit losses based upon historical experience, changes in current market conditions, expected losses and any specific customer collection issue that is identified.
Derivatives and Hedging Activity
Our derivative and hedging activities included in the accompanying Condensed Consolidated Balance Sheets, Condensed Consolidated Statements of Income and Condensed Consolidated Statements of Comprehensive Income are detailed below and in Note 8.
The operations of our Utilities, including natural gas sold by our Gas Utilities and natural gas used by our Electric Utilities’ generation plants or those plants under PPAs where our Electric Utilities must provide the generation fuel (tolling agreements), expose our utility customers to natural gas price volatility. Therefore, as allowed or required by state utility commissions, we have entered into commission approved hedging programs utilizing natural gas futures, options, over-the-counter swaps and basis swaps to reduce our customers’ underlying exposure to these fluctuations. These transactions are considered derivatives, and in accordance with accounting standards for derivatives and hedging, mark-to-market adjustments are recorded as Derivative assets or Derivative liabilities on the accompanying Condensed Consolidated Balance Sheets, net of balance sheet offsetting as permitted by GAAP.
For our regulated Utilities’ hedging plans, unrealized and realized gains and losses, as well as option premiums and commissions on these transactions, are recorded as Regulatory assets or Regulatory liabilities in the accompanying Condensed Consolidated Balance Sheets in accordance with the state regulatory commission guidelines. When the related costs are recovered through our rates, the hedging activity is recognized in the Condensed Consolidated Statements of Income.
We use wholesale power purchase and sale contracts to manage purchased power costs and load requirements associated with serving our electric customers. Periodically, certain wholesale energy contracts are considered derivative instruments due to not qualifying for the normal purchase and normal sales exception to derivative accounting. Changes in the fair value of these commodity derivatives are recognized in the Condensed Consolidated Statements of Income.
We buy, sell and deliver natural gas at competitive prices by managing commodity price risk. As a result of these activities, this area of our business is exposed to risks associated with changes in the market price of natural gas. We manage our exposure to such risks using over-the-counter and exchange traded options and swaps with counterparties in anticipation of forecasted purchases and sales during time frames ranging from April 2022 through December 2024. A portion of our over-the-counter swaps have been designated as cash flow hedges to mitigate the commodity price risk associated with deliveries under fixed price forward contracts to deliver gas to our Choice Gas Program customers. The gain or loss on these designated derivatives is reported in AOCI in the accompanying Condensed Consolidated Balance Sheets and reclassified into earnings in the same period that the underlying hedged item is recognized in earnings. Effectiveness of our hedging position is evaluated at least quarterly.
The contract or notional amounts and terms of the electric and natural gas derivative commodity instruments held at our Utilities are composed of both long and short positions. We had the following net long positions as of:

| March 31, 2022 |  | December 31, 2021 |  |
| Notional Amounts (MMBtus) |  | Maximum Term (months) (a) |  | Notional Amounts (MMBtus) |  | Maximum Term (months) (a) |  |  |  |
Natural gas futures purchased | — |  |  | 0 |  | 590,000 |  |  | 3 |  |  |  |
Natural gas options purchased, net | — |  |  | 0 |  | 3,100,000 |  |  | 3 |  |  |  |
Natural gas basis swaps purchased | — |  |  | 0 |  | 870,000 |  |  | 3 |  |  |  |
Natural gas over-the-counter swaps, net (b) | 2,750,000 |  |  | 33 |  | 4,570,000 |  |  | 34 |  |  |  |
Natural gas physical contracts, net (c) | 4,181,531 |  |  | 21 |  | 16,416,677 |  |  | 24 |  |  |  |

__________
(a) Term reflects the maximum forward period hedged.
(b) As of March 31, 2022, 410,000 MMBtus of natural gas over-the-counter swaps purchases were designated as cash flow hedges.
(c) Volumes exclude derivative contracts that qualify for the normal purchases and normal sales exception permitted by GAAP.
We have certain derivative contracts which contain credit provisions. These credit provisions may require the Company to post collateral when credit exposure to the Company is in excess of a negotiated line of unsecured credit. At March 31, 2022, the Company posted $0.3 million related to such provisions, which is included in Other current assets on the Condensed Consolidated Balance Sheets.

Total | $ | (154) |  | $ | 886 |  |  | $ | 1,541 |  | $ | (744) |

As of March 31, 2022, $1.8 million of net losses related to our interest rate swaps and commodity derivatives are expected to be reclassified from AOCI into earnings within the next 12 months. As market prices fluctuate, estimated and actual realized gains or losses will change during future periods.
Derivatives Not Designated as Hedge Instruments
The following table summarizes the impacts of derivative instruments not designated as hedge instruments on our Condensed Consolidated Statements of Income for the three months ended March 31, 2022 and 2021. Note that this presentation does not reflect the expected gains or losses arising from the underlying physical transactions; therefore, it is not indicative of the economic profit or loss we realized when the underlying physical and financial transactions were settled.

As discussed above, financial instruments used in our regulated Gas Utilities are not designated as cash flow hedges. However, there is no earnings impact because the unrealized gains and losses arising from the use of these financial instruments are recorded as Regulatory assets or Regulatory liabilities. The net unrealized losses included in our Regulatory asset accounts related to these financial instruments in our Gas Utilities were $0.2 million and $2.6 million as of March 31, 2022 and December 31, 2021, respectively. For our Electric Utilities, the unrealized gains and losses arising from these derivatives are recognized in the Condensed Consolidated Statements of Income.
(8) Fair Value Measurements
We use the following fair value hierarchy for determining inputs for our financial instruments. Our assets and liabilities for financial instruments are classified and disclosed in one of the following fair value categories:
Level 1 — Unadjusted quoted prices available in active markets that are accessible at the measurement date for identical unrestricted assets or liabilities. Level 1 instruments primarily consist of highly liquid and actively traded financial instruments with quoted pricing information on an ongoing basis.
Level 2 — Pricing inputs include quoted prices for identical or similar assets and liabilities in active markets other than quoted prices in Level 1, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability and inputs that are derived principally from or corroborated by observable market data by correlation or other means.
Level 3 — Pricing inputs are generally less observable from objective sources. These inputs reflect management’s best estimate of fair value using its own assumptions about the assumptions a market participant would use in pricing the asset or liability.
Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the placement within the fair value hierarchy levels. We record transfers, if necessary, between levels at the end of the reporting period for all of our financial instruments.
Transfers into Level 3, if any, occur when significant inputs used to value the derivative instruments become less observable, such as a significant decrease in the frequency and volume in which the instrument is traded, negatively impacting the availability of observable pricing inputs. Transfers out of Level 3, if any, occur when the significant inputs become more observable, such as when the time between the valuation date and the delivery date of a transaction becomes shorter, positively impacting the availability of observable pricing inputs.
Recurring Fair Value Measurements
Derivatives
The commodity contracts for our Utilities segments are valued using the market approach and include forward strip pricing at liquid delivery points, exchange-traded futures, options, basis swaps and over-the-counter swaps and options (Level 2) for wholesale electric energy and natural gas contracts. For exchange-traded futures, options and basis swap assets and liabilities, fair value was derived using broker quotes validated by the exchange settlement pricing for the applicable contract. For over-the-counter instruments, the fair value is obtained by utilizing a nationally recognized service that obtains observable inputs to compute the fair value, which we validate by comparing our valuation with the counterparty. The fair value of these swaps includes a credit valuation adjustment based on the credit spreads of the counterparties when we are in an unrealized gain position or on our own credit spread when we are in an unrealized loss position. For additional information, see Note 1 of our Notes to the Consolidated Financial Statements in our 2021 Annual Report on Form 10-K.

(a) As of December 31, 2021, $2.4 million of our commodity derivative assets and $1.8 million of our commodity derivative liabilities, as well as related gross collateral amounts, were subject to master netting agreements.
Pension and Postretirement Plan Assets
Fair value measurements also apply to the valuation of our pension and postretirement plan assets. Current accounting guidance requires employers to annually disclose information about the fair value measurements of their assets of a defined benefit pension or other postretirement plan. The fair value of these assets is presented in Note 13 to the Consolidated Financial Statements included in our 2021 Annual Report on Form 10-K.
Other Fair Value Measures
The carrying amount of cash and cash equivalents, restricted cash and equivalents and short-term borrowings approximates fair value due to their liquid or short-term nature. Cash, cash equivalents and restricted cash are classified in Level 1 in the fair value hierarchy. Notes payable consist of commercial paper borrowings and are not traded on an exchange; therefore, they are classified as Level 2 in the fair value hierarchy.

__________
(a) Long-term debt is valued based on observable inputs available either directly or indirectly for similar liabilities in active markets and therefore is classified in Level 2 in the fair value hierarchy. Carrying amount of long-term debt is net of deferred financing costs.
(9) Other Comprehensive Income
We record deferred gains (losses) in AOCI related to interest rate swaps designated as cash flow hedges, commodity contracts designated as cash flow hedges and the amortization of components of our defined benefit plans. Deferred gains (losses) for our commodity contracts designated as cash flow hedges are recognized in earnings upon settlement, while deferred gains (losses) related to our interest rate swaps are recognized in earnings as they are amortized.

(11) Income Taxes
Income Tax Expense and Effective Tax Rates
Three Months Ended March 31, 2022 Compared to the Three Months Ended March 31, 2021
Income tax expense for the three months ended March 31, 2022 was $14.5 million compared to $0.5 million reported for the same period in 2021. For the three months ended March 31, 2022, the effective tax rate was 10.7% compared to 0.5% for the same period in 2021. The higher effective tax rate is primarily due to $7.6 million of prior year tax benefits from Colorado Electric TCJA-related bill credits to customers (which were offset by reduced revenue).
(12) Business Segment Information
Our CODM reviews financial information presented on an operating segment basis for purposes of making decisions and assessing financial performance. Our CODM assesses the performance of our operating segments based on operating income.
For the first nine months of 2021, we had reported four operating segments: Electric Utilities, Gas Utilities, Power Generation and Mining. In the fourth quarter of 2021, we changed our operating segments to align with the revised manner in which our CODM reviews our financial performance and allocates resources. Our power generation and mining businesses, which were previously presented as separate operating segments, are now part of our Electric Utilities segment. This change aligns with our vertically integrated business model for our Electric Utilities. Comparative periods presented reflect this change.
Our operating segments are equivalent to our reportable segments.
Segment information was as follows (in thousands):

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following discussions should be read in conjunction with the Notes contained herein and Management's Discussion and Analysis of Financial Condition and Results of Operations appearing in the 2021 Form 10-K.
Executive Summary
We are a customer-focused energy solutions provider that invests in our communities’ safety, sustainability and growth with a mission of Improving Life with Energy and a vision to be the Energy Partner of Choice. The Company’s core mission— and our primary focus — is to provide safe, reliable and cost-effective electric and natural gas service to 1.3 million utility customers in over 800 communities in eight states, including Arkansas, Colorado, Iowa, Kansas, Montana, Nebraska, South Dakota and Wyoming.
Recent Developments
Winter Storm Uri
In February 2021, a prolonged period of historic cold temperatures across the central United States, which covered all of our Utilities’ service territories, caused a substantial increase in heating and energy demand and contributed to unforeseeable and unprecedented market prices for natural gas and electricity. As a result of Winter Storm Uri, we incurred significant incremental natural gas and fuel costs.
In 2021, our Utilities submitted cost recovery applications with the utility commissions in our state jurisdictions to recover incremental costs associated with Winter Storm Uri. To date, we have received final commission approval for all of our Winter Storm Uri cost recovery applications with the exception of Arkansas Gas and Wyoming Gas (which are both approved for interim cost recovery). See Note 2 of the Notes to Condensed Consolidated Financial Statements for further information.
Macroeconomic Trends
We are monitoring emerging macroeconomic trends including inflationary pressures on the prices of commodities, materials, outside services and employee costs; supply chain constraints; and a competitive and tightening labor market. To date, we have experienced limited net impacts from these trends. However, the situation remains fluid and it is difficult to predict.
We have seen an increase in commodity energy costs that had an effect on customer bills. Our utilities have regulatory mechanisms that allow them to pass prudently incurred costs of energy through to the customer, which mitigates our exposure. Customer billing rates are adjusted periodically to reflect changes in our cost of energy.
We are proactively managing through increased costs of materials and supply chain disruptions to achieve our forecasted capital investment targets. We have already contracted a significant majority of the materials needed for our 2022 capital program. We have also evaluated each of our forecasted projects and will prioritize depending on future constraints. Project delays may occur if costs rise significantly or if materials are not available.
We are faced with increased competition for employee and contractor talent in the current labor market. To date, we have seen increased employee costs related to attraction and retention of talent offset by decreases in headcount compared to the prior year.
More detailed discussion of the future uncertainties can be found in “Risk Factors” section in Part I, Item 1A of our 2021 Annual Report on Form 10-K.
Business Segment Recent Developments
Electric Utilities
•On February 23, 2022, Wyoming Electric set a new winter peak load of 262 MW, surpassing the previous winter peak of 252 MW set on January 5, 2022.
•On February 15, 2022, Wyoming Electric submitted a request to the WPSC seeking approval for a CPCN to construct an estimated 260-mile transmission expansion project. As proposed, the approximately $260 million transmission expansion project, known as Ready Wyoming, would provide customers long-term price stability and greater flexibility as power markets develop in the Western States. If approved, construction of the project would take place in multiple phases or segments spanning 2023 through 2025 and would interconnect South Dakota Electric’s and Wyoming Electric’s transmission systems.
28

Table of Contents
•On January 26, 2022, Colorado Electric agreed to join SPP’s Western Energy Imbalance Service Market. Colorado Electric will join the market in April 2023 and will continue to study long-term solutions for joining or developing an organized wholesale market. The expansion allows the utilities to participate in a real-time market to dispatch energy at lower costs.
•In January 2022, South Dakota Electric placed in service a $19 million, 54-mile, 230 kV electric transmission line from Rapid City to Spearfish, South Dakota. The second leg of this transmission line rebuild project, an 85-mile segment from Spearfish to Gillette, Wyoming, is expected to be in service by the end of 2023.
•On January 5, 2022, South Dakota Electric and Wyoming Electric set new winter peak loads. Wyoming Electric’s new winter peak load of 252 MW surpasses the previous peak of 247 MW set in December 2019. South Dakota Electric’s new winter peak of 327 MW surpasses the previous winter peak of 326 MW set in February 2021.
Gas Utilities
•See Note 2 of the Notes to Condensed Consolidated Financial Statements for recent rate review activity for Arkansas Gas.
Corporate and Other
•On April 13, 2022, a jury awarded $41 million for claims made by GT Resources, LLC (“GTR”) against BHC and two of its subsidiaries (Black Hills Exploration and Production, Inc. and Black Hills Gas Resources, Inc.), which ceased oil and natural gas operations in 2018 as part of BHC’s decision to exit the exploration and production business. The claims involved a dispute over a 2.3-million-acre concession award in Costa Rica which was acquired by a BHC subsidiary in 2003. We believe we have meritorious defenses to the verdict and intend to appeal the verdict. See additional information in Note 3 of the Notes to Condensed Consolidated Financial Statements.
Results of Operations
Certain lines of business in which we operate are highly seasonal, and revenue from, and certain expenses for, such operations may fluctuate significantly among quarterly periods. Demand for electricity and natural gas is sensitive to seasonal cooling, heating and industrial load requirements. In particular, the normal peak usage season for our Electric Utilities is June through August while the normal peak usage season for our Gas Utilities is November through March. Significant earnings variances can be expected between the Gas Utilities segment’s peak and off-peak seasons. Due to this seasonal nature, our results of operations for the three months ended March 31, 2022 and 2021, and our financial condition as of March 31, 2022 and December 31, 2021, are not necessarily indicative of the results of operations and financial condition to be expected as of or for any other period or for the entire year.
In the fourth quarter of 2021, we integrated our power generation and mining businesses within the Electric Utilities segment. The alignment is consistent with the current way our CODM evaluates the performance of the business and makes decisions related to the allocation of resources. Comparative periods presented reflect this change. See further segment information in Note 1 2 of the Notes to Condensed Consolidated Financial Statements.
Segment information does not include inter-company eliminations and all amounts are presented on a pre-tax basis unless otherwise indicated. Minor differences in amounts may result due to rounding.

Three Months Ended March 31, 2022 Compared to Three Months Ended March 31, 2021
The variance to the prior year included the following:
•Electric Utilities’ operating income increased $11 million primarily due to prior year impacts related to Colorado Electric’s TCJA-related bill credits to customers (which were offset by reduced income tax expense), increased off-system energy sales, and prior year impacts related to Winter Storm Uri partially offset by higher operating expenses;
•Gas Utilities’ operating income increased $21 million primarily due to new rates and rider recovery, prior year impacts from Winter Storm Uri, favorable mark-to-market adjustments on wholesale commodity contracts and customer growth partially offset by higher operating expenses;
•Corporate and Other expenses decreased $2.2 million primarily due to an allocation of a 2020 employee cost true-up in the first quarter of 2021, which was offset in our business segments;
•Interest expense increased $0.9 million due to higher debt balances; and
•Income tax expense increased $14 million driven by higher pre-tax income and a higher effective tax rate due to prior year tax benefits from Colorado Electric TCJA-related bill credits.
Segment Operating Results
A discussion of operating results from our business segments follows.
Non-GAAP Financial Measure
The following discussion includes financial information prepared in accordance with GAAP, as well as another financial measure, Electric and Gas Utility margin, that is considered a “non-GAAP financial measure.” Generally, a non-GAAP financial measure is a numerical measure of a company’s financial performance, financial position or cash flows that excludes (or includes) amounts that are included in (or excluded from) the most directly comparable measure calculated and presented in accordance with GAAP. Electric and Gas Utility margin (revenue less cost of sales) is a non-GAAP financial measure due to the exclusion of operation and maintenance expenses, depreciation and amortization expenses, and property and production taxes from the measure.
Electric Utility margin is calculated as operating revenue less cost of fuel and purchased power. Gas Utility margin is calculated as operating revenue less cost of natural gas sold. Our Electric and Gas Utility margin is impacted by the fluctuations in power and natural gas purchases and other fuel supply costs. However, while these fluctuating costs impact Electric and Gas Utility margin as a percentage of revenue, they only impact total Electric and Gas Utility margin if the costs cannot be passed through to our customers.

Our Electric and Gas Utility margin measure may not be comparable to other companies’ Electric and Gas Utility margin measures. Furthermore, this measure is not intended to replace operating income as determined in accordance with GAAP as an indicator of operating performance.

Three Months Ended March 31, 2022 Compared to the Three Months Ended March 31, 2021:
Electric Utility margin increased as a result of the following:

| (in millions)
Prior year TCJA-related bill credits (a) | $ | 9.3 |
Off-system energy sales and transmission services | 3.7 |
Prior year Winter Storm Uri impacts (b) | 3.6 |
New rates and rider recovery | 1.7 |
Mark-to-market on wholesale energy contracts | 1.5 |
Customer load growth | 1.3 |
Lower pricing on new Wygen I PPA | (2.5) |
Weather | (0.2) |
Other | 0.6 |
Total increase in Electric Utility margin | $ | 19.0 |

__________
(a) In February 2021, Colorado Electric delivered TCJA-related bill credits to its customers. These bill credits were offset by a reduction in income tax expense and resulted in a minimal impact to Net income.
(b) As a result of Winter Storm Uri, we incurred a $3.2 million negative impact to our regulated wholesale power margins due to higher fuel costs and $2.1 million of incremental fuel costs that are not recoverable through our fuel cost recovery mechanisms partially offset by $1.7 million of increased Electric Utility margin realized under Black Hills Wyoming’s Economy Energy PSA.
31

Table of Contents
Operations and maintenance expense increased primarily due to higher cloud computing licensing costs and higher maintenance costs related to planned spring outages at the Gillette, Wyoming energy complex.
Depreciation and amortization increased primarily due to a higher asset base driven by prior year capital expenditures.

Three Months Ended March 31, 2022 Compared to the Three Months Ended March 31, 2021
Operating Activities:
Net cash provided by (used in) operating activities was $650 million higher than the same period in 2021. The variance to the prior year was primarily attributable to:
•Cash earnings (net income plus non-cash adjustments) were $37 million higher for the three months ended March 31, 2022 compared to the same period in the prior year primarily due to increased Electric and Gas Utility margins driven by new rates and rider recovery and prior year impacts from Winter Storm Uri.
37

Table of Contents
•Net inflows from changes in certain operating assets and liabilities were $611 million higher, primarily attributable to:
◦Cash inflows increased by $637 million as a result of changes in our regulatory assets and liabilities primarily driven by prior year incremental fuel, purchased power and natural gas costs due to Winter Storm Uri, current year recovery of a portion of Winter Storm Uri incremental and carrying costs from customers, and higher recoveries of gas and fuel cost adjustments driven by higher commodity prices;
◦Cash inflows decreased by $41 million as a result of changes in accounts receivable and other current assets primarily driven by higher pass-through revenues reflecting higher commodity prices partially offset by lower natural gas in storage inventories; and
◦Cash outflows decreased by $15 million as a result of decreases in accounts payable and accrued liabilities primarily driven by payment timing of natural gas and power purchases and other working capital requirements.
•Cash inflows increased by $2.0 million for other operating activities.
Investing Activities:
Net cash used in investing activities was $8 million lower than the same period in 2021. The variance to the prior year was primarily attributable to:
•Capital expenditures of $137 million for the three months ended March 31, 2022 compared to $146 million for the same period in the prior year. Lower current year expenditures were driven by lower programmatic safety, reliability and integrity spending at our Gas and Electric Utilities; and
•Cash outflows increased by $1.1 million for other investing activities.
Financing Activities:
Net cash used in financing activities was $658 million higher than the same period in 2021. The variance to the prior year was primarily attributable to:
•Cash inflows decreased $659 million due to short-term and long-term repayments in excess of borrowings. This decrease was primarily driven by $600 million of net borrowings from our term loan in the prior year;
•Cash inflows increased $3.8 million due to higher issuances of common stock; and
•Cash outflows increased $3.0 million due to increased dividends paid on common stock.
