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 2023 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;

•
The effects of changing interest rates;

•
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;

•
Our ability to obtain sufficient insurance coverage at reasonable costs and whether such coverage will protect us against significant losses; 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.

(1)
Manage ment’s Statement

The unaudited Consolidated Financial Statements included herein have been prepared by Black Hills Corporation (together with our subsidiaries the “Company”, “us”, “we”, or “our”), pursuant to the rules and regulations of the SEC. 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 Consolidated Financial Statements should be read in conjunction with the consolidated financial statements and the notes included in our 2023 Annual Report on Form 10-K.

Use of Estimates and Basis of Presentation

The information furnished in the accompanying 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 September 30, 2024, December 31, 2023, and September 30, 2023, 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

Improvements to Reportable Segment Disclosures, ASU 2023-07

In November 2023, the FASB issued ASU 2023-07, Improvements to Reportable Segment Disclosures, which expands public entities’ segment disclosures by requiring disclosure of significant segment expenses that are regularly reviewed by the CODM and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment’s profit or loss and assets. ASU 2023-07 also allows, in addition to the measure that is most consistent with GAAP, the disclosure of additional measures of segment profit or loss that are used by the CODM in assessing segment performance and deciding how to allocate resources. ASU 2023-07 is effective for our Annual Report on Form 10-K for the fiscal year ended December 31, 2024, and subsequent interim periods, with early adoption permitted. We do not expect ASU 2023-07 to have an impact on our financial position, results of operations and cash flows; however, are currently evaluating the impact on our consolidated financial statement disclosures.

Improvements to Income Tax Disclosures, ASU 2023-09

In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures, which expands public entities’ annual disclosures by requiring disclosure of tax rate reconciliation amounts and percentages for specific categories, income taxes paid disaggregated by federal and state taxes, and income tax expense disaggregated by federal and state taxes jurisdiction. ASU 2023-09 is effective for our Annual Report on Form 10-K for the fiscal year ended December 31, 2025, with early adoption permitted. We do not expect ASU 2023-09 to have an impact on our financial position, results of operations and cash flows; however, are currently evaluating the impact on our consolidated financial statement disclosures.

Disaggregation of Income Statement Expenses, ASU 2024-03

In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses, which requires public entities to disclose, in the notes to financial statements, certain costs and expenses, such as purchases of inventory, employee compensation, and costs related to depreciation and amortization. ASU 2024-03 is effective for our Annual Report on Form 10-K for the fiscal year ended December 31, 2027, and subsequent interim periods, with early adoption permitted. We do not expect ASU 2024-03 to have an impact on our financial position, results of operations and cash flows; however, are currently evaluating the impact on our consolidated financial statement disclosures.

Comm itments, 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 2023 Annual Report on Form 10-K except as described below.

Manufactured Gas Plant

In 2008, we acquired whole and partial liabilities for former manufactured gas plant sites in Nebraska and Iowa, which were previously used to convert coal to natural gas. The acquisition provided for an insurance recovery, now valued at $1.5 million recorded in Other assets, non-current on our Consolidated Balance Sheets, which will be used to help offset remediation costs. During the nine months ended September 30, 2024, we increased our Iowa manufactured gas plant site remediation cost estimate by $7.4 million based on recent site investigations and remediation work completed, which resulted in a corresponding increase in our Accrued liabilities and Regulatory assets. As of September 30, 2024, we had an Accrued liability of $11.5 million and a Regulatory asset of $10.6 million on our Consolidated Balance Sheets for the remediation of the manufactured gas plant site in Iowa. The remediation cost estimate could change materially due to results of further investigations, actions of environmental agencies or the financial viability of other responsible parties.

Short-term Debt

Revolving Credit Facility and CP Program

On May 31, 2024, we amended and restated our corporate Revolving Credit Facility, maintaining total commitments of $750 million and extending the term through May 31, 2029, with two one-year extension options (subject to consent from lenders). This facility is similar to the former revolving credit facility, which includes an accordion feature that allows us, with the consent of the administrative agent, the issuing agents and each bank increasing or providing a new commitment, to increase total commitments up to $1.0 billion. Borrowings continue to be available under a base rate or various SOFR options. Based on our current credit ratings, the margins for base rate borrowings, SOFR borrowings and letters of credit will be 0.125%, 1.125%, and 1.125%, respectively, and a 0.175% commitment fee will be charged on unused amounts.

Our Revolving Credit Facility and CP Program, which are classified as Notes payable on the Consolidated Balance Sheets, had the following borrowings, outstanding letters of credit, and available capacity as of:

| September 30, 2024 |  | December 31, 2023 |
| (dollars in millions) |
Amount outstanding | $ | 17.5 |  | $ | - |
Letters of credit (a) | $ | 3.5 |  | $ | 3.7 |
Available capacity | $ | 729.0 |  | $ | 746.3 |
Weighted average interest rates |  | 4.93 | % | N/A |

(a)
Letters of credit are off-balance sheet commitments that reduce the borrowing capacity available on our corporate Revolving Credit Facility.

Revolving Credit Facility and CP Program borrowing activity was as follows:

| Nine Months Ended September 30, |
| 2024 |  | 2023 |
| (dollars in millions) |
Maximum amount outstanding (based on daily outstanding balances) | $ | 25.8 |  | $ | 548.7 |
Average amount outstanding (based on daily outstanding balances) | $ | 0.6 |  | $ | 109.2 |
Weighted average interest rates |  | 5.15 | % |  | 4.91 | %

Long-term Debt

On May 16, 2024, we completed a public debt offering of $450 million, 6.00% senior unsecured notes due January 15, 2035. Proceeds from the offering, which were net of $5.2 million of deferred financing costs, along with available cash and short-term borrowings under our existing facilities were used to repay all $600 million principal amount outstanding of our 1.04% senior unsecured notes on their August 23, 2024, maturity date and for other general corporate purposes.

Financial Covenants

Revolving Credit Facility

We were in compliance with all of our Revolving Credit Facility covenants as of September 30, 2024. We are required to maintain a Consolidated Indebtedness to Capitalization Ratio not to exceed 0.65 to 1.00. Subject to applicable cure periods, a violation of this covenant would constitute an event of default that entitles the lenders to terminate their remaining commitments and accelerate all principal and interest outstanding. As of September 30, 2024, our Consolidated Indebtedness to Capitalization Ratio was 0.55 to 1.00.

Wyoming Electric

Wyoming Electric was in compliance with all covenants within its financing agreements as of September 30, 2024. Wyoming Electric is required to maintain a debt to capitalization ratio of no more than 0.60 to 1.00. As of September 30, 2024, Wyoming Electric's debt to capitalization ratio was 0.52 to 1.00.

Risk Mana gement 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 weather, geopolitical events, pandemics, market speculation, recession, 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.

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.

We perform periodic 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 Consolidated Balance Sheets, Consolidated Statements of Income, and 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 enter 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 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 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 Consolidated Statements of Income.

To support our Choice Gas Program customers, 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 October 2024 through August 2026. 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 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.

(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 September 30, 2024, the Company post ed $0.5 million re lated to such provisions, which is included in Other current assets on the Consolidated Balance Sheets.

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. We had $3.2 million in net unrealized losses i ncluded in our Regulatory asset accounts related to these financial instruments in our Gas Utilities as of September 30, 2024, and the amount was $5.1 million as of December 31, 2023.

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.

22

Table of Contents

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 2023 Annual Report on Form 10-K.

The following tables set forth, by level within the fair value hierarchy, our gross assets and gross liabilities and related offsetting as permitted by GAAP that were accounted for at fair value on a recurring basis for derivative instruments.

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 2023 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.

The following table presents the carrying amounts and fair values of financial instruments not recorded at fair value on the Consolidated Balance Sheets as of:

| September 30, 2024 |  | December 31, 2023 |
| Carrying Amount |  | Fair Value |  | Carrying Amount |  | Fair Value |

(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.

Other Compr ehensive 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.

The following table details reclassifications out of AOCI and into Net income. The amounts in parentheses below indicate decreases to Net income in the Consolidated Statements of Income for the period, net of tax:

Inco me Taxes

Transfers of Production Tax Credits

In August 2022, President Biden signed H.R. 5376 into law, commonly known as the Inflation Reduction Act of 2022, or IRA. The IRA contains a tax credit transferability provision that allows us to transfer (e.g. sell) PTCs produced after December 31, 2022, to third parties. In June 2024, under this transferability provision, we entered into an agreement with a third party to sell $16.9 million of our 2023 generated PTCs. We elected to account for the net proceeds from the transfer of PTCs as a reduction to income taxes payable under the scope of ASC 740 Income Taxes. We included the discount from the sale of our tax credits as a component of income tax expense. This sale of tax credits is presented within operating activities in the Consolidated Statement of Cash Flows consistent with the presentation of cash taxes paid.

We expect to continue to explore the ability to efficiently monetize our tax credits through third party transferability agreements. We will also include any expected proceeds from the sale of tax credits in the evaluation of the realizability of deferred tax assets related to PTCs.

IRS Revenue Procedure 2023-15

On April 14, 2023, the IRS released Revenue Procedure 2023-15 Amounts paid to improve tangible property. The Revenue Procedure provides a safe harbor method of accounting that taxpayers may use to determine whether costs to repair, maintain, replace, or improve natural gas transmission and distribution property must be capitalized. The Revenue Procedure may be adopted in tax years ending after May 1, 2023. We intend to elect the safe harbor for tax year 2024. We do not expect the Revenue Procedure to have a material impact on our tax repairs deduction.

Income Tax Benefit (Expense) and Effective Tax Rates

Three Months Ended September 30, 2024, Compared to the Three Months Ended September 30, 2023

Income tax (expense) for the three months ended September 30, 2024, was $(2.9) million compared to $(7.4) million reported for the same period in 2023. For the three months ended September 30, 2024, the effective tax rate was 10.0% compared to 13.1% for the same period in 2023. The lower effective tax rate was primarily driven by favorable return-to-accrual adjustments.

Nine Months Ended September 30, 2024, Compared to the Nine Months Ended September 30, 2023

Income tax (expense) for the nine months ended September 30, 2024, was $(23.6) million compared to $(16.0) million reported for the same period in 2023. For the nine months ended September 30, 2024, the effective tax rate was 11.4% which compared to 7.6% for the same period in 2023. The higher effective tax rate was primarily driven by a prior year $8.2 million tax benefit from a Nebraska income tax rate decrease.

Business Segme nt Information

We conduct our business operations through two operating segments: Electric Utilities and Gas Utilities. Certain unallocated corporate expenses that support our operating segments are presented as Corporate and Other. Corporate and Other also includes business development activities that are not part of our operating segments and inter-segment eliminations. Our operating segments are equivalent to our reportable segments.

Our Chief Executive Officer, who is considered to be our CODM, reviews financial information presented on an operating segment basis for purposes of making decisions, allocating resources, and assessing financial performance. Our CODM assesses the performance of our operating segments based on operating income. Our CODM reviews capital expenditures by operating segment rather than any individual or total asset amount.

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 2023 Form 10-K.

Executive Summary

We are a customer-focused energy solutions provider with a mission of Improving Life with Energy for more than 1.3 million customers and 800+ communities we serve. Our aspiration is to be the trusted energy partner across our growing eight-state footprint, including Arkansas, Colorado, Iowa, Kansas, Montana, Nebraska, South Dakota, and Wyoming. Our strategy is centered on four critical priorities: Growth—to grow strategically and achieve strong financial performance, Operational Excellence—delivering safe, reliable and cost-effective energy to meet our customers’ needs, Transformation—be a simple and connected company positioned for growth, and People & Culture—retain and attract a talented, engaged and thriving team.

We conduct our business operations through two operating segments: Electric Utilities and Gas Utilities. Certain unallocated corporate expenses that support our operating segments are presented as Corporate and Other. We conduct our utility operations under the name Black Hills Energy predominantly in rural areas of the Rocky Mountains and Midwestern states. We consider ourself a domestic electric and natural gas utility company.

We have provided energy and served customers for 140 years, since the 1883 gold rush days in Deadwood, South Dakota. Throughout our history, the common thread that unites the past to the present is our commitment to serve our customers and communities. By being responsive and service focused, we can help our customers and communities thrive while meeting rapidly changing customer expectations.

Recent Developments

Environmental Matters - Power Plant Greenhouse Gas Regulations

In April 2024, the EPA published final rules addressing control of CO 2 emissions from the power sector. The rules regulate new natural gas generating units and provide emission guidelines for existing coal and certain natural gas generation. The rules create subcategories of coal units based on planned retirement date and subcategories of natural gas combustion turbines and combined cycle units based on utilization. The CO 2 control requirements vary by subcategory. We are currently evaluating the impact of these rules through our integrated resource plans and believe that costs incurred as a result of the new rules will be recoverable through our regulatory mechanisms.

Business Segment Recent Developments

Electric Utilities

•
See Note 2 of the Condensed Notes to Consolidated Financial Statements for recent rate review activity for Colorado Electric.

•
South Dakota Electric continues to pursue adding 100 MW of utility-owned, dispatchable natural gas generation by the second half of 2026. During the first quarter of 2025, South Dakota Electric expects to file for a permit to construct the project in South Dakota and request a CPCN in Wyoming.

•
Wyoming Electric continues construction on Ready Wyoming, which is on schedule and expected to be completed in multiple segments in 2024 and 2025.

•
On July 11, 2024, Wyoming Electric announced its partnership with Meta to provide power for its newest AI data center to be constructed in Cheyenne, Wyoming. Wyoming Electric will serve Meta under its Large Power Contract Service tariff and will procure customized energy resources essential to Meta's operations and sustainability objectives.

•
On April 17, 2024, Colorado Electric filed its 120-Day report with the CPUC recommending the addition of renewable energy resources to advance its Clean Energy Plan. The final composition of resources and timing is subject to review and approval by the CPUC, which is expected later this year.

Gas Utilities

•
See Note 2 of the Condensed Notes to Consolidated Financial Statements for recent rate review activity for Arkansas Gas, Colorado Gas, Iowa Gas, and Wyoming Gas.

•
In January 2024, Black Hills Energy Renewable Resources acquired a RNG production facility at a landfill in Dubuque, Iowa. The facility currently injects RNG into the natural gas distribution system serving Dubuque, which is owned and operated by Iowa Gas. This acquisition represents our entry into the production of RNG as a non-regulated business while leveraging our expertise in owning and operating regulated natural gas pipeline systems, including RNG interconnections. The RNG produced from the landfill facility captures methane that would otherwise vent into the atmosphere. It is delivered under long-term contracts to a third party that purchases the RNG and its related environmental attributes, in conformity with the EPA's Renewable Fuel Standard Program.

Corporate and Other

•
See Note 5 of the Condensed Notes to Consolidated Financial Statements for information regarding our ATM program activity and our May 16, 2024, debt offering.

•
On May 31, 2024, we amended and restated our corporate Revolving Credit Facility. See Note 5 of the Notes to Condensed Consolidated Financial Statements for further information.

•
During the second quarter of 2024, we published our 2023 Corporate Sustainability Report, highlighting our environmental, social and governance impacts and our progress on major projects and climate goals. We reported a 27% reduction in greenhouse gas emissions from our natural gas distribution system since 2022 and are on track to achieve our goal of net zero emissions by 2035. Additionally, we have reduced our electric utility greenhouse gas emissions by nearly one-third since 2005 and are on track to achieve our goals to reduce electric emissions intensity by 40% by 2030 and 70% by 2040 compared to 2005.

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 and nine months ended September 30, 2024, and 2023, and our financial condition as of September 30, 2024, and December 31, 2023, 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.

All amounts are presented on a pre-tax basis unless otherwise indicated. Minor differences in amounts may result due to rounding.

Segment Operating Results

A discussion of operating results from our business segments follows. Unless otherwise indicated, segment information does not include inter-segment eliminations.

Non-GAAP Financial Measures

The following discussion includes financial information prepared in accordance with GAAP and a “non-GAAP financial measure", Electric and Gas Utility margin. 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 September 30, 2024, Compared to the Three Months Ended September 30, 2023:

Electric Utility margin decreased as a result of the following:

| (in millions) |
New rates and rider recovery | $ | 4.2 |
Weather |  | 1.6 |
Retail customer growth and usage |  | 1.1 |
Prior Year Wygen I revenue recovery under business interruption insurance (a) |  | (5.0 | )
Off-system excess energy sales |  | (2.8 | )
Unplanned generation outages |  | (2.3 | )
Other |  | (1.1 | )
| $ | (4.3 | )

(a)
In 2021, Wygen I experienced an unplanned outage which resulted in lost revenue. A claim for these losses was submitted under our business interruption insurance policy. During the third quarter of 2023, we recovered $5.0 million from our business interruption insurance which was recognized as Revenue.

Operations and maintenance expense increased primarily due to a prior-year $3.9 million gain on sale of land, $3.2 million of costs related to unplanned generation outages, $1.6 million of higher office, facility and IT-related expenses, $1.4 million of higher insurance expense and $1.1 million of higher employee costs.

Depreciation and amortization increased primarily due to a higher asset base driven by current year and prior year capital expenditures.

Taxes - property and production was comparable to the same period in the prior year.

In 2021, Wygen I experienced an unplanned outage which resulted in lost revenue. A claim for these losses was submitted under our business interruption insurance policy. During the third quarter of 2023, we recovered $5.0 million from our business interruption insurance which was recognized as Revenue.

Operations and maintenance expense increased primarily due to a prior-year one-time $7.7 million gain on the sale of Northern Iowa Windpower assets, a prior-year $3.9 million gain on sale of land, $4.2 million of costs related to unplanned generation outages and $3.0 million of higher insurance expense, partially offset by $2.1 million of lower employee-related expenses driven by lower headcount. Other favorable variances, none of which were individually significant, comprised the remainder of the difference when compared to the same period in the prior year.

Depreciation and amortization increased primarily due to a higher asset base driven by current year and prior year capital expenditures.

Taxes - property and production was comparable to the same period in the prior year.

Net cash provided by operating activities was $189.9 million lower than the same period in 2023. The variance to the prior year was primarily attributable to:

•
Total earnings (net income plus non-cash adjustments) were $34.2 million higher for the nine months ended September 30, 2024, compared to the same period in the prior year primarily due to increased Electric and Gas Utility margins driven by new rates and increased rider revenues.

•
Net inflows from changes in certain operating assets and liabilities were $224.3 million lower, primarily attributable to:

•
Cash inflows decreased by $211.5 million as a result of changes in materials, supplies, fuel, accounts receivable, and other current assets primarily driven by fluctuations in commodity prices and weather conditions;

•
Cash outflows decreased by $124.7 million as a result of changes in accounts payable and accrued liabilities primarily driven by fluctuations in commodity prices, payment timing of natural gas and power purchases, and changes in other working capital requirements; and

•
