MGE is a wholly owned subsidiary of MGE Energy and represents a majority of its assets, liabilities, revenues, expenses, and operations. Thus, all information contained in this report relates to, and is filed by, MGE Energy.

Forward-Looking Statements

This report, and other documents filed by MGE Energy and MGE with the Securities and Exchange Commission (SEC) from time to time, contain forward-looking statements that reflect management's current assumptions and estimates regarding future performance and economic conditions—especially as they relate to economic conditions, future load growth, revenues, expenses, capital expenditures, financial resources, regulatory matters, and the scope and expense associated with future environmental regulation. These forward-looking statements are made pursuant to the provisions of the Private Securities Litigation Reform Act of 1995. Words such as "believe," "expect," "anticipate," "estimate," "could," "should," "intend," "will," and other similar words, and words relating to goals, targets and projections, generally identify forward-looking statements. Both MGE Energy and MGE caution investors that these forward-looking statements are subject to known and unknown risks and uncertainties that may cause actual results to differ materially from those projected, expressed, or implied.

The factors that could cause actual results to differ materially from the forward-looking statements made by a registrant include: (a) those factors discussed in the registrants' 2021 Annual Report on Form 10-K : Item 1A. Risk Factors, Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations, as updated by Part I, Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations in this report, and Item 8. Financial Statements and Supplementary Data – Note 16, as updated by Part I, Item 1. Financial Statements – Note 8 in this report, and (b) other factors discussed herein and in other filings made by that registrant with the SEC.

Readers are cautioned not to place undue reliance on these forward-looking statements, which apply only as of the date of this report. MGE Energy and MGE undertake no obligation to release publicly any revision to these forward-looking statements to reflect events or circumstances after the date of this report, except as required by law.

MGE Energy, Inc., and Madi son Gas and Electric Company

Notes to Conso lidated Financial Statements (unaudited)

September 30, 2022

Summary of Significa nt Accounting Policies – MGE Energy and MGE.

Basis of Presentation.

This report is a combined report of MGE Energy and MGE. References in this report to "MGE Energy" are to MGE Energy, Inc. and its subsidiaries. References in this report to "MGE" are to Madison Gas and Electric Company.

MGE Power Elm Road and MGE Power West Campus own electric generating assets and lease those assets to MGE. Both entities are variable interest entities under applicable authoritative accounting guidance. MGE is considered the primary beneficiary of these entities as a result of contractual agreements. As a result, MGE has consolidated MGE Power Elm Road and MGE Power West Campus. See Footnote 3 of Notes to Consolidated Financial Statements under Item 8, Financial Statements and Supplementary Data, of MGE Energy's and MGE's 2021 Annual Report on Form 10-K (the 2021 Annual Report on Form 10-K ).

The accompanying consolidated financial statements as of September 30, 2022, and during the three and nine months ended, are unaudited but include all adjustments that MGE Energy and MGE management consider necessary for a fair statement of their respective financial statements. All adjustments are of a normal, recurring nature except as otherwise disclosed. The year-end consolidated balance sheet information was derived from the audited balance sheet appearing in the 2021 Annual Report on Form 10-K but does not include all disclosures required by accounting principles generally accepted in the United States of America. These notes should be read in conjunction with the financial statements and the notes on pages 61 through 115 of the 2021 Annual Report on Form 10-K .

Cash, Cash Equivalents, and Restricted Cash.

The following table presents the components of total cash, cash equivalents, and restricted cash on the consolidated balance sheets.


	MGE Energy				MGE
	September 30,		December 31,		September 30,		December 31,
(In thousands)	2022		2021		2022		2021
Cash and cash equivalents	$	10,615	$	17,438	$	4,475	$	6,401
Restricted cash		651		847		651		847
Receivable - margin account		1,969		550		1,969		550
Cash, cash equivalents, and restricted cash	$	13,235	$	18,835	$	7,095	$	7,798

Cash Equivalents

All highly liquid investments purchased with an original maturity of three months or less are considered to be cash equivalents.

Restricted Cash

MGE has certain cash accounts that are restricted to uses other than current operations and designated for a specific purpose. MGE's restricted cash accounts include cash held by trustees for certain employee benefits and cash deposits held by third parties. These are included in "Other current assets" on the consolidated balance sheets.

Receivable – Margin Account

Cash amounts held by counterparties as margin collateral for certain financial transactions are recorded as Receivable – margin account in "Other current assets" on the consolidated balance sheets. The costs being hedged are fuel for electric generation, purchased power, and cost of gas sold.

Property, Plant, and Equipment.

Columbia.

An asset that will be retired in the near future and substantially in advance of its previously expected retirement date is subject to abandonment accounting. In the second quarter of 2021, the operator of Columbia received approval from MISO to retire Columbia Units 1 and 2. The co-owners initially intended to retire Unit 1 by the end of 2023 and Unit 2 by the end of 2024. In June 2022, the target retirement date for both Units was updated to June 2026 after consideration by the owners of supply chain disruptions impacting the completion dates of current and planned renewable generation projects and the impact of those delays upon energy supply availability, reliability and cost. The postponement is not expected to affect MGE's goal to achieve 80% carbon reduction by 2030. Final timing and retirement dates are subject to change depending on operational, regulatory, and other factors. As of September 30, 2022, early retirement of Columbia was probable.

The net book value of our ownership share of this generating unit was $ 150.9 million as of September 30, 2022. This amount was classified as plant to be retired within "Property, plant, and equipment, net" on the consolidated balance sheets. Assets for Columbia Unit 1 and Unit 2 are currently included in rate base, and MGE continues to depreciate them on a straight-line basis using the composite depreciation rates approved by the PSCW that included retirement dates of 2029 for Unit 1 and 2038 for Unit 2. MGE is currently seeking approval from the PSCW in its 2023 electric rate case limited reopener to revise the depreciation schedule for Columbia Unit 2 to 2029 to align with Unit 1. See Footnote 9 for further details on MGE's rate proceedings.

If it becomes probable that regulators will disallow full recovery or a return on the remaining net book value of a generating unit that is either abandoned or probable of being abandoned, an impairment loss would be required. An impairment loss would be recorded to the extent that the remaining net book value of the generating unit exceeds the present value of the amount expected to be recovered from ratepayers. No impairment was recorded as of September 30, 2022 .

New Ac counti ng Standards - MGE Energy and MGE.

MGE Energy and MGE reviewed FASB authoritative guidance recently issued, none of which are expected to have a material impact on their consolidated results of operations, financial condition, or cash flows.

Investme nt in ATC and ATC Holdco - MGE Energy and MGE.

ATC owns and operates electric transmission facilities primarily in Wisconsin. MGE received an interest in ATC when it, like other Wisconsin electric utilities, contributed its electric transmission facilities to ATC as required by Wisconsin law. That interest is presently held by MGE Transco, a subsidiary of MGE Energy. ATC Holdco was formed by several members of ATC, including MGE Energy, to pursue electric transmission development and investments outside of Wisconsin. The ownership interest in ATC Holdco is held by MGEE Transco, a subsidiary of MGE Energy.

MGE Transco and MGEE Transco have accounted for their investments in ATC and ATC Holdco, respectively, under the equity method of accounting. Equity earnings from investments are recorded as "Other income" on the consolidated statements of income of MGE Energy. MGE Transco recorded the following amounts related to its investment in ATC:


	Three Months Ended				Nine Months Ended
	September 30,				September 30,
(In thousands)	2022		2021		2022		2021
Equity earnings from investment in ATC	$	1,473	$	2,500	$	6,543	$	7,333
Dividends received from ATC		2,005		1,942		5,964		5,842
Capital contributions to ATC		536		—		2,319		—

ATC Holdco was formed in December 2016. ATC Holdco's transmission development activities have been suspended for the near term.

In October 2022, MGE Transco made a $ 0.4 million capital contribution to ATC.

ATC's summarized financial data is as follows:


	Three Months Ended						Nine Months Ended
	September 30,						September 30,
(In thousands)	2022			2021			2022			2021

Earnings before members' income taxes	$	37,628		$	66,894		$	172,734		$	197,378

MGE receives transmission and other related services from ATC. During the three and nine months ended September 30, 2022, MGE recorded $ 7.9 million and $ 23.6 million, respectively, for transmission services compared to $ 8.0 million and $ 24.0 million for comparable periods in 2021. MGE also provides a variety of operational, maintenance, and project management work for ATC, which is reimbursed by ATC. As of September 30, 2022, and December 31, 2021, MGE had a receivable due from ATC of $ 4.6 million and $ 7.0 million, respectively. The receivable is primarily related to transmission interconnection activities at Badger Hollow and Paris solar generation sites. MGE will be reimbursed for these costs after the new generation assets are placed into service.

Taxes - MGE E nergy and MGE.

Effective Tax Rate.

The consolidated income tax provision differs from the amount computed by applying the statutory federal income tax rate to income before income taxes, as follows:

(a)

Included are impacts of the 2017 Tax Act for the regulated utility for excess deferred taxes recognized using a normalization method of accounting in recognition of IRS rules that restrict the rate at which the excess deferred taxes may be returned to utility customers. For the three months ended September 30, 2022 and 2021, MGE recognized $ 1.0 million and $ 0.7 million, respectively. For the nine months ended September 30, 2022 and 2021, MGE recognized $ 2.9 million and $ 2.0 million, respectively. Included in the 2021 rate settlement was a one-time return to customers of the electric portion of excess deferred taxes related to the 2017 Tax Act not restricted by IRS normalization rules. For the three and nine months ended September 30, 2021, MGE recognized $ 3.3 million and $ 9.9 million, respectively. Included in the 2022 and 2023 rate settlement was a net collection from customers of the gas portion of deficient deferred taxes related to the 2017 Tax Act not restricted by IRS normalization rules. For the three and nine months ended September 30, 2022, MGE recognized $ 0.3 million and $ 1.0 million, respectively.

Pensi on and Other Postretirement Plans - MGE Energy and MGE.

MGE maintains qualified and nonqualified pension plans, health care, and life insurance benefits and defined contribution 401(k) benefit plans for its employees and retirees.

The components of net periodic benefit cost, other than the service cost component, are recorded in "Other income, net" on the consolidated statements of income. The service cost component is recorded in "Other operations and maintenance" on the consolidated statements of income. MGE has regulatory treatment and recognizes regulatory assets or liabilities for timing differences between when net periodic benefit costs are recovered and when costs are recognized.

As approved by the PSCW, MGE is allowed to defer differences between actual employee benefit plan costs and costs reflected in current rates. The deferred costs may be recovered or refunded in MGE's next rate filing. During the three and nine months ended September 30, 2022, MGE recovered $ 0.2 million and $ 0.8 million of pension and other postretirement costs, respectively, compared to approximately $ 0.3 million and $ 3.9 million for the comparable periods in 2021. The recovery of these costs reduced the amount previously deferred and has not been reflected in the table above.

During the three and nine months ended September 30, 2022 , MGE deferred and recorded as a regulatory liability $ 0.3 million and $ 1.1 million, respectively, of savings from employee benefit plan costs compared to $ 2.8 million and $ 5.4 million for the comparable periods in 2021. During the three and nine months ended September 30, 2022, MGE refunded in rates $ 1.0 million and $ 3.1 million, respectively, of savings from 2021 employee benefit plan costs. The deferred savings has not been reflected in the table above.

Equity and Fi nancing Arrangements.

Common Stock - MGE Energy.

MGE Energy sells shares of its common stock through its Direct Stock Purchase and Dividend Reinvestment Plan (the Stock Plan). Those shares may be newly issued shares or shares that are purchased in the open market by an independent agent for participants in the Stock Plan. Sales of newly issued shares under the Stock Plan are covered by a shelf registration statement that MGE Energy filed with the SEC.

During the three and nine months ended September 30, 2022 and 2021 , MGE Energy issued no new shares of common stock under the Stock Plan.

Dilutive Shares Calculation - MGE Energy.

As of September 30, 2022, 10,331 shares were included in the calculation of diluted earnings per share related to nonvested equity awards. See Footnote 7 for additional information on share-based compensation awards.

Long-Term Debt Iss uance - MGE Energy and MGE.

On November 1, 2022, MGE entered into a private placement Note Purchase Agreement in which it committed to issue $ 25 million of new long-term debt (Series A), carrying an interest rate of 5.43 % per annum over its 10-year life, $ 15 million of new long-term debt (Series B), carrying an interest rate of 5.43 % per annum over its 10-year life, and $ 35 million of new long-term debt (Series C), carrying an interest rate of 5.53 % per annum over its 12-year life. Funding will occur on December 1, 2022 for Series A and on February 28, 2023 for Series B and Series C. The proceeds of the debt financing will be used to assist with capital expenditures and other corporate obligations. The covenants of this debt are substantially consistent with MGE's existing unsecured long-term debt.

Share-Based C ompensation - MGE Energy and MGE.

During the three and nine months ended September 30, 2022, MGE recorded $ 0.6 million in compensation benefit and $ 0.1 million in compensation expense, respectively, related to share-based compensation awards under the 2006 Performance Unit Plan, the 2020 Performance Unit Plan, the 2013 Director Incentive Plan, and the 2021 Long-Term Incentive Plan (2021 Plan) compared to $ 0.3 million and $ 1.6 million in compensation expense for the comparable periods in 2021.

In January 2022, cash payments of $ 1.8 million were distributed related to awards that were granted in 2019 under the 2013 Director Incentive Plan, and in 2017 under the 2006 Performance Unit Plan.

In February 2022, MGE issued 10,395 performance units and 15,931 restricted stock units under the 2021 Plan to eligible employees and non-employee directors.

MGE recognizes stock-based compensation expense on a straight-line basis over the requisite service period. Awards classified as equity awards are measured based on their grant-date fair value. Awards classified as liability awards are recorded at fair value each reporting period. The performance units can be paid out in either cash, shares of common stock or a combination of cash and stock and are classified as a liability award. The restricted stock units will be paid out in shares of common stock, and therefore are classified as equity awards.

Commitmen ts and Contingencies.

Environmental - MGE Energy and MGE.

In February 2021, MGE and the other co-owners of Columbia announced plans to retire that facility. The co-owners intend to retire Unit 1 and Unit 2 by June 2026. Final timing and retirement dates are subject to change depending on operational, regulatory, and other factors. Effects of environmental compliance requirements discussed below will depend upon the final retirement dates approved and compliance requirement dates.

MGE Energy and MGE are subject to frequently changing local, state, and federal regulations concerning air quality, water quality, land use, threatened and endangered species, hazardous materials handling, and solid waste disposal. These regulations affect the manner in which operations are conducted, the costs of operations, as well as capital and operating expenditures. Several of these environmental rules are subject to legal challenges, reconsideration and/or other uncertainties. Regulatory initiatives, proposed rules, and court challenges to adopted rules could have a material

effect on capital expenditures and operating costs. Management believes compliance costs will be recovered in future rates based on previous treatment of environmental compliance projects.

These initiatives, proposed rules, and court challenges include:

•

The EPA's promulgated water Effluent Limitations Guidelines (ELG) and standards for steam electric power plants which focus on the reduction of metals and other pollutants in wastewater from new and existing power plants.

In July 2021, the PSCW approved a Certificate of Authority (CA) application filed by MGE and the other owners of Columbia. The CA application commits to close Columbia ' s wet pond system (as described in further detail in the CCR section below). By committing to close the wet pond system, Columbia will be in compliance with ELG requirements.

The Elm Road Units must satisfy the ELG rule's requirements no later than December 2023, as determined by the permitting authority. In December 2021, the PSCW approved a CA application for installation of additional wastewater treatment equipment to comply with the ELG Rule. MGE's share of the costs to comply with the rule is estimated to be approximately $ 4 million. Construction began in March 2022 and will extend into 2023.

•

The EPA's cooling water intake rules require cooling water intake structures at electric power plants to meet best technology available (BTA) standards to reduce the mortality from entrainment (drawing aquatic life into a plant's cooling system) and impingement (trapping aquatic life on screens).

Blount's WPDES permit assumes that the plant meets BTA standards for the duration of the permit, which expires in 2023. Before the next permit renewal, MGE is required to complete an entrainment study and recommend a BTA along with alternative technologies considered. MGE completed the entrainment study in 2021 and submitted the results to the WDNR. The WDNR will make the final BTA determination and include any BTA requirements in Blount's next permit renewal, which is expected to be completed by the end of 2022 and effective in 2023. Management believes that the BTA determination at Blount will not be material for MGE.

Columbia's river intakes are subject to this rule. Columbia's operator received a permit in 2019 requiring studies of intake structures to be submitted to the WDNR by November 2023 to help determine BTA. BTA improvements may not be required given that the owners are planning to retire both units by June of 2026. MGE will continue to work with Columbia's operator to evaluate all regulatory requirements applicable to the planned retirements.

MGE does not expect this rule to have a material effect on its existing plants.

•

Greenhouse Gas (GHG) reduction guidelines and approval criteria established under the Clean Air Act for states to use in developing plans to control GHG emissions from fossil fuel-fired electric generating units (EGUs), including existing and proposed regulations governing existing, new or modified fossil-fuel generating units.

In October 2021, as part of the Biden administration's Unified Agenda, the EPA announced its intention to issue a new rule to reduce greenhouse gas emissions from existing fossil fuel-fired EGUs. In June 2022, the U.S. Supreme Court held that the Clean Air Act does not authorize the EPA to regulate GHG emissions using generation shifting (e.g., shifting from coal to natural gas and/or renewable generation sources). MGE will continue to evaluate greenhouse gas rule developments, including any new EPA actions towards rule development, and any further court decisions on the EPA ' s authority to regulate greenhouse gases.

•

The EPA's rule to regulate ambient levels of ozone through the 2015 Ozone National Ambient Air Quality Standards (NAAQS).

The Elm Road Units are located in Milwaukee County, Wisconsin, a nonattainment area. In October 2022, the EPA reclassified Milwaukee County from "marginal" to "moderate" nonattainment under the 2015 ozone NAAQS. The Wisconsin Department of Natural Resources (WDNR) must develop a State Implementation Plan (SIP) for the area, and this reclassification will result in more stringent SIP requirements for both constructing new development and modifying or expanding existing plants in the area. The deadline for moderate classified areas to meet attainment standards is August 2024. MGE will continue to monitor the WDNR's SIP development and the extent to which the requirements will impact the Elm Road Units. At this time, the operator of the Elm Road Units does not expect that the 2015 Ozone NAAQS will have a material effect on its existing plants based on final designations.

•

Rules regulating nitrogen oxide (NO x ) and sulfur dioxide (SO 2 ) emissions, including the Cross State Air Pollution Rule (CSAPR) and Clean Air Visibility Rule.

The EPA's CSAPR and its progeny are a suite of interstate air pollution transport rules designed to reduce ozone and fine particulate (PM2.5) ambient air levels in areas that the EPA has determined as being significantly impacted by pollution from upwind states. This is accomplished in the CSAPR through a reduction in SO 2 and NO x from qualifying fossil-fuel fired power plants in upwind "contributing" states. NO x and SO 2 contribute to fine particulate pollution and NO x contributes to ozone formation in downwind areas. Reductions are generally achieved through a cap-and-trade system. Individual plants can meet their caps through reducing emissions and/or buying allowances on the market.

In April 2022, the EPA published a proposed Federal Implementation Plan (FIP) to address state obligations under the Clean Air Act "good neighbor" provisions for the 2015 Ozone NAAQS. This proposed rule impacts 26 states, including Wisconsin, and is designed to both revise the current NO x CSAPR ozone season cap-and-trade obligations for fossil-fuel generated power plants and add NO x limitations for certain industries in specified states. For Wisconsin, the proposed rule includes revisions to the current obligations for fossil-fuel power generation as well as the new limitations for certain industries.

If finalized, the proposed rule would be effective beginning with the 2023 ozone season and start with emissions budgets that can be achieved with what the EPA has defined as immediately available measures, including consistently operating emissions controls already installed at power plants. In 2026, additional obligations would go into effect, including potential daily emissions limits and technology upgrades to coal-fired power plants without existing emission controls. Wisconsin would need to submit a SIP to meet its obligations or accept the EPA's proposed FIP.

MGE has met its current CSAPR obligations through a combination of reduced emissions through pollution control (e.g., SCR installation at Columbia), and owned, received, and purchased allowances. MGE expects the rule, if finalized as written, to impact our fossil-fueled generation assets. However, we will not know the impact of this rule with any certainty until it is finalized. We will continue to monitor rule developments.

•

The EPA's Coal Combustion Residuals (CCR) Rule.

The CCR rule regulates as a solid waste coal ash from burning coal for the purpose of generating electricity and defines what ash use activities would be considered generally exempt beneficial reuse of coal ash. The CCR rule also regulates landfills, ash ponds, and other surface impoundments used for coal combustion residuals by regulating their design, location, monitoring, and operation. The CCR rule requires owners or operators of coal-fired power plants to stop transporting CCR and non-CCR wastewater to unlined surface impoundments. In addition, regulated entities must initiate impoundment closure as soon as feasible and in no event later than April 2021, unless the EPA grants an extension. A site-specific extension to initiate closure of the primary ash pond at Columbia by December 31, 2022 was requested. The EPA has not formally approved the extension.

In July 2021, the PSCW approved a CA application filed by MGE and the other owners of Columbia to install technology required to cease bottom ash transport water discharges rather than extend the longevity of the ash ponds. Construction of the coal combustion residuals system that will replace the unlined surface impoundment is undergoing final testing. Construction is expected to be completed by the end of 2022. MGE's share of the costs of the project is expected to be approximately $ 4 million.

Review of the Elm Road Units has indicated that the costs to comply with the CCR rule are not expected to be significant.

Legal Matters - MGE Energy and MGE.

MGE is involved in various legal matters that are being defended and handled in the normal course of business. MGE accrues for costs that are probable of being incurred and subject to reasonable estimation. The accrued amount for these matters is not material to the financial statements. MGE does not expect the resolution of these matters to have a material adverse effect on its consolidated results of operations, financial condition, or cash flows.

Certain environmental groups filed petitions against the PSCW regarding MGE's two most recent rate settlements. MGE has intervened in the petitions in cooperation with the PSCW. See Footnote 9.a. for more information regarding this matter.

Pur chase Contracts - MGE Energy and MGE.

MGE Energy and MGE have entered into various commodity supply, transportation, and storage contracts to meet their obligations to deliver electricity and natural gas to customers. Management expects to recover these costs in future customer rates. The following table shows future commitments related to purchase contracts as of September 30, 2022:


(In thousands)	2022		2023		2024		2025		2026		Thereafter

(a)

Total coal commitments for the Columbia and Elm Road Units, including transportation. Fuel procurement for MGE's jointly owned Columbia and Elm Road Units is handled by WPL and WEPCO, respectively, who are the operators of those facilities.

(b)

MGE's natural gas transportation and storage contracts require fixed monthly payments for firm supply pipeline transportation and storage capacity. The pricing components of the fixed monthly payments for the transportation and storage contracts are established by FERC but may be subject to change.

(c)

These commitments include market-based pricing.

(d)

Operational commitments for solar and wind facilities.

Rate Proceedings.


	Rate increase	Return on Common Equity	Common Equity Component of Regulatory Capital Structure	Effective Date
Approved 2021 settlement (a)
Electric	— %	9.8 %	55.8 %	1/1/2021
Gas	4.00 %	9.8 %	55.8 %	1/1/2021
Approved 2022/2023 settlement (b)
Electric	8.81 %	9.8 %	55.6 %	1/1/2022
Gas	2.15 %	9.8 %	55.6 %	1/1/2022
Gas	0.96 %	9.8 %	55.6 %	1/1/2023
Proposed limited 2023 reopener (c)
Electric	4.38 %	9.8 %	55.6 %	1/1/2023

(a)

The electric rate settlement included an increase in rate base but the associated rate increase was primarily offset by lower fuel and purchased power costs and a one-time $ 18.2 million return to customers of the portion of excess deferred taxes related to the 2017 Tax Act not restricted by IRS normalization rules. The gas rate increase covered infrastructure costs and technology improvements. The settlement agreement also included escrow accounting treatment for pension and other postretirement benefit costs, bad debt expense, and customer credit card fees. Escrow accounting treatment allows MGE to defer any difference between estimated costs in rates and actual costs incurred until a future rate filing. Any difference would be recorded as a regulatory asset or regulatory liability.

(b)

The electric and gas rate increases were driven by an increase in rate base including our investments in Badger Hollow I and a new customer information system. Also driving the requested electric increase were higher fuel and purchased power costs as well as the completion in 2021 of the one-time return of the electric excess deferred tax credit related to the 2017 Tax Act not restricted by IRS normalization rules. Included in the electric residential rate is a reduction in the customer charge.

(c)

The electric rate increase is driven by generation assets including our investments in Badger Hollow II (solar), Paris (solar and battery), Red Barn (wind), and West Riverside (natural gas). In addition, the reopener request includes a reduction in fuel costs, which MGE has partially offset with the recovery of deferred 2021 fuel costs. Changes in the fuel forecast are updated in the limited reopener filing prior to the final PSCW approval. The reopener also revises the depreciation schedule for Columbia Unit 2 and shared equipment to 2029 to align with the depreciation schedule for Columbia Unit 1. PSCW approval of the 2023 limited reopener is pending. A final order is expected before the end of the year.

Sierra Club and Vote Solar have filed petitions with the Dane County Circuit Court seeking review of the PSCW decision approving MGE's two most recent rate settlements (2021 and 2022/2023). The PSCW is named as the responding party; MGE is not named as a party. The petitions challenge the process the PSCW used to approve the portion of the settlements relating to electric rates and the electric customer fixed charge that does not vary with usage. The requested relief is unclear. The revenue requirement approved by the PSCW in the settlements have not been challenged. The PSCW is expected to vigorously defend its approval of the rate case settlements. MGE has intervened in the proceedings to further defend the PSCW's decision.

Fu el Rules.

Fuel rules require Wisconsin utilities to defer electric fuel-related costs that fall outside a symmetrical cost tolerance band around the amount approved for a utility in its annual fuel proceedings. Any over- or under-recovery of the actual costs is determined in the following year and is then reflected in future billings to electric retail customers. The fuel rules bandwidth is set at plus or minus 1 % . The electric fuel-related costs are subject to an excess revenues test. Excess revenues are defined as revenues in the year in question that provide MGE with a greater return on common equity than authorized by the PSCW in MGE's latest rate order. The recovery of under-collected electric fuel-related costs would be reduced by the amount that exceeds the excess revenue test. These costs are subject to the PSCW's annual review of fuel costs completed in the year following the deferral. The following table summarized deferred electric fuel-related costs:


	Fuel Costs ( in millions )	Refund or Recovery Period
2019 deferred fuel savings	$( 1.5 ) (a)	January 2021 through December 2021
2020 deferred fuel savings	$( 3.2 ) (a)	October 2021
2021 deferred fuel costs	3.3 (a)	January 2023 through December 2023 (b)
2022 deferred fuel costs	$ 4.4	(c)

(a)

There was no change to the recovery (refund) in the fuel rules proceedings from the amount MGE deferred .

(b)

In August 2022, the PSCW issued a final decision in the 2021 fuel rules proceedings for MGE to include the recovery of these costs as part of the 2023 electric limited reopener.

(c)

These costs will be subject to the PSCW's annual review of 2022 fuel costs, expected to be completed in 2023.

Derivati ve and Hedging Instruments - MGE Energy and MGE.

Purpose.

As part of its regular operations, MGE enters into contracts, including options, swaps, futures, forwards, and other contractual commitments, to manage its exposure to commodity prices. To the extent that these contracts are derivatives, MGE assesses whether or not the normal purchases or normal sales exclusion applies. For contracts to which this exclusion cannot be applied, the derivatives are recognized in the consolidated balance sheets at fair value. MGE's financial commodity derivative activities are conducted in accordance with its electric and gas risk management program, which is approved by the PSCW and limits the volume MGE can hedge with specific risk management strategies. The maximum length of time over which cash flows related to energy commodities can be hedged is four years . If the derivative qualifies for regulatory deferral, the derivatives are marked to fair value and are offset with a corresponding regulatory asset or liability depending on whether the derivative is in a net loss or net gain position, respectively. The deferred gain or loss is recognized in earnings in the delivery month applicable to the instrument. Gains and losses related to hedges qualifying for regulatory treatment are recoverable in gas rates through the PGA or in electric rates as a component of the fuel rules mechanism.

Notional Amounts.

The gross notional volume of open derivatives is as follows:

Financial Statement Presentation.

MGE purchases and sells exchange-traded and over-the-counter options, swaps, and future contracts. These arrangements are primarily entered into to help stabilize the price risk associated with gas or power purchases. These transactions are employed by both MGE's gas and electric segments. Additionally, as a result of the firm transmission agreements that MGE holds on electricity transmission paths in the MISO market, MGE holds financial transmission rights (FTRs). An FTR is a financial instrument that entitles the holder to a stream of revenues or charges based on the differences in hourly day-ahead energy prices between two points on the transmission grid. The fair values of these instruments are offset with a corresponding regulatory asset/liability depending on whether they are in a net loss/gain position. Depending on the nature of the instrument, the gain or loss associated with these transactions will be reflected as cost of gas sold, fuel for electric generation, or purchased power expense in the delivery month applicable to the instrument. As of September 30, 2022, and December 31, 2021, the fair value of exchange traded derivatives and FTRs exceeded their cost basis by $ 5.2 million and $ 2.8 million, respectively.

MGE was a party to a purchased power agreement that provided MGE with firm capacity and energy during a base term from June 1, 2012, through May 31, 2022. The agreement was accounted for as a derivative contract and was recognized at its fair value on the consolidated balance sheets. However,

the derivative qualified for regulatory deferral and was recognized with a corresponding regulatory asset or liability depending on whether the fair value was in a loss or gain position. The actual cost was recognized in purchased power expense in the month of purchase.

The following table summarizes the fair value of the derivative instruments on the consolidated balance sheets. All derivative instruments in this table are presented on a gross basis and are calculated prior to the netting of instruments with the same counterparty under a master netting agreement as well as the netting of collateral. For financial statement purposes, instruments are netted with the same counterparty under a master netting agreement as well as the netting of collateral.

PPA		( 2,642	)		—			( 759	)		—

MGE's commodity derivative contracts, FTRs, and PPA are subject to regulatory deferral. These derivatives are marked to fair value and are offset with a corresponding regulatory asset or liability. Realized gains and losses are deferred on the consolidated balance sheets and are recognized in earnings in the delivery month applicable to the instrument. As a result of the treatment described above, there are no unrealized gains or losses that flow through earnings.

Certain counterparties extend MGE a credit limit. If MGE exceeds these limits, the counterparties may require collateral to be posted. As of September 30, 2022, and December 31, 2021 , no counterparties were in a net liability position.

Nonperformance of counterparties to the non-exchange traded derivatives could expose MGE to credit loss. However, MGE enters into transactions only with companies that meet or exceed strict credit guidelines, and it monitors these counterparties on an ongoing basis to mitigate nonperformance risk in its portfolio. As of September 30, 2022 , no counterparties had defaulted.

Fair Value of Fin ancial Instruments - MGE Energy and MGE.

Fair value is defined as the price that would be received to sell an asset or would be paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. The accounting standard clarifies that

fair value should be based on the assumptions market participants would use when pricing the asset or liability including assumptions about risk. The standard also establishes a three-level fair value hierarchy based upon the observability of the assumptions used and requires the use of observable market data when available. The levels are:

Level 1 - Pricing inputs are quoted prices within active markets for identical assets or liabilities.

Level 2 - Pricing inputs are quoted prices within active markets for similar assets or liabilities; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations that are correlated with or otherwise verifiable by observable market data.

Level 3 - Pricing inputs are unobservable and reflect management's best estimate of what market participants would use in pricing the asset or liability.

Fair Value of Financial Assets and Liabilities Recorded at the Carrying Amount.

The carrying amount of cash, cash equivalents, and outstanding commercial paper approximates fair market value due to the short maturity of those investments and obligations. The estimated fair market value of long-term debt is based on quoted market prices for similar financial instruments. Since long-term debt is not traded in an active market, it is classified as Level 2. The estimated fair market value of financial instruments are as follows:


	September 30, 2022				December 31, 2021
(In thousands)	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Long-term debt (a)	$	619,794	$	549,585	$	623,449	$	729,914

(a)

Includes long-term debt due within one year. Excludes debt issuance costs and unamortized discount of $ 3.9 million and $ 4.3 million as of September 30, 2022, and December 31, 2021 , respectively.

(b)

No collateral was posted against derivative positions as of September 30, 2022 .

(c)

As of December 31, 2021 MGE received collateral of $ 1.3 million from counterparties under a master netting agreement for outstanding exchange traded derivative positions. The fair value of the derivative asset disclosed in this table has not been reduced for the collateral received.

Investments include exchange-traded investment securities valued using quoted prices on active exchanges and are therefore classified as Level 1.

The deferred compensation plan allows participants to defer certain cash compensation into a notional investment account. These amounts are included within other deferred liabilities in the consolidated balance sheets. The notional investments earn interest based upon the semiannual rate of U.S. Treasury Bills having a 26 -week maturity increased by 1 % compounded monthly with a minimum annual rate of 7 %, compounded monthly. The notional investments are based upon observable market data, however, since the deferred compensation obligations themselves are not exchanged in an active market, they are classified as Level 2.

Derivatives include exchange-traded derivative contracts, over-the-counter transactions, a purchased power agreement, and FTRs. Most exchange-traded derivative contracts are valued based on unadjusted quoted prices in active markets and are therefore classified as Level 1. A small number of exchange-traded derivative contracts are valued using quoted market pricing in markets with insufficient volumes and are therefore considered unobservable and classified as Level 3. Transactions done with an over-the-counter party are on inactive markets and are therefore classified as Level 3. These transactions are valued based on quoted prices from markets with similar exchange-traded transactions. FTRs are priced based upon monthly auction results for identical or similar instruments in a closed market with limited data available and are therefore classified as Level 3.

The purchased power agreement, with a term ended May 2022, (see Footnote 10 ) was valued using an internal pricing model and therefore was classified as Level 3. See the 2021 Annual Report on Form 10-K for details on the internal pricing model and significant unobservable inputs.

(d)

MGE's exchange-traded derivative contracts, over-the-counter party transactions, purchased power agreement, and FTRs are subject to regulatory deferral. These derivatives are therefore marked to fair value and are offset in the financial statements with a corresponding regulatory asset or liability.

Item 2. Man agement's Discussion and Analysis of Financial Condition and Results of Operations.

General

MGE Energy is an investor-owned public utility holding company operating through subsidiaries in five business segments:

•

Regulated electric utility operations, conducted through MGE,

•

Regulated gas utility operations, conducted through MGE,

•

Nonregulated energy operations, conducted through MGE Power and its subsidiaries,

•

Transmission investments, representing our equity investment in ATC and ATC Holdco, and

•

All other, which includes corporate operations and services.

Our principal subsidiary is MGE, which generates and distributes electric energy, distributes natural gas, and represents a majority portion of our assets, liabilities, revenues, and expenses. MGE generates, purchases, and distributes electricity to approximately 159,000 customers in Dane County, Wisconsin, including the city of Madison, and purchases and distributes natural gas to approximately 169,000 customers in the Wisconsin counties of Columbia, Crawford, Dane, Iowa, Juneau, Monroe, and Vernon.

Our nonregulated energy operations own interests in electric generating capacity that is leased to MGE. The ownership/leasing structure was adopted under applicable state regulatory guidelines for MGE's participation in these generation facilities, consisting principally of a stable return on the equity investment in the new generation facilities over the term of the related leases. The nonregulated energy operations include an ownership interest in two coal-fired generating units in Oak Creek, Wisconsin and a partial ownership of a cogeneration project on the UW-Madison campus. A third party operates the units in Oak Creek, and MGE operates the cogeneration project. Due to the nature of MGE's participation in these facilities, the results of MGE Energy's nonregulated operations are also consolidated into MGE's consolidated financial position and results of operations under applicable accounting standards.

Executive Overview

Our primary focus today and for the foreseeable future is our core utility customers at MGE as well as creating long-term value for our shareholders. MGE continues to face the challenge of providing its customers with reliable power at competitive prices. MGE works on meeting this challenge by investing in more efficient generation projects, including renewable energy sources. As we work toward achieving 80% carbon reduction by 2030 (from 2005 levels), MGE continues to examine and pursue opportunities to reduce the proportion that coal generation represents in its generation mix, as evidenced by its most recent announcements of the retirement of Columbia (a coal generation plant), the planned change in the Elm Road Units fuel source from coal to natural gas, and its growing ownership of renewable generation sources. MGE will continue to focus on growing earnings while controlling operating and fuel costs. MGE's goal is to provide safe and efficient operations in addition to providing customer value. We believe it is critical to maintain a strong credit rating consistent with financial strength in MGE in order to accomplish these goals.

We principally earn revenue and generate cash from operations by providing electric and natural gas utility services, including electric power generation and electric power and gas distribution. The earnings and cash flows from the utility business are sensitive to various external factors, including:

•

Weather, and its impact on customer sales,

•

Economic conditions, including current business activity and employment and their impact on customer demand,

•

Regulation and regulatory issues, and their impact on the timing and recovery of costs,

•

Energy commodity prices, including natural gas prices,

•

Equity price risk pertaining to pension related assets,

•

Credit market conditions, including interest rates and our debt credit rating,

•

Environmental laws and regulations, including adopted and pending environmental rule changes,

•

Impacts on activity arising from COVID-19 and its variants, including government restrictions on activity,

increased employee health and welfare costs, precautions for dealing with members of the public, and supply chain disruptions, and

•

Other factors listed in "Item 1A. Risk Factors" in our 2021 Annual Report on Form 10-K .

During the three months ended September 30, 2022, MGE Energy's earnings were $33.7 million or $0.93 per share compared to $34.9 million or $0.97 per share during the same period in the prior year. MGE's earnings during the three months ended September 30, 2022, were $27.2 million compared to $27.4 million during the same period in the prior year.

During the nine months ended September 30, 2022, MGE Energy's earnings were $89.9 million or $2.49 per share compared to $92.7 million or $2.56 per share during the same period in the prior year. MGE's earnings during the nine months ended September 30, 2022, were $68.5 million compared to $70.8 million during the same period in the prior year.

MGE Energy's net income was derived from our business segments as follows:


	Three Months Ended				Nine Months Ended
(In millions)	September 30,				September 30,
Business Segment:	2022		2021		2022		2021
Electric Utility	$	27.6	$	27.8	$	55.2	$	60.0
Gas Utility		(0.4)		(0.2)		12.8		11.6
Nonregulated Energy		5.6		5.4		16.5		15.9
Transmission Investments		1.1		1.8		4.8		5.4
All Other		(0.2)		0.1		0.6		(0.2)
Net Income	$	33.7	$	34.9	$	89.9	$	92.7

Our net income during the three and nine months ended September 30, 2022, compared to the same periods in the prior year primarily reflects the effects of the following factors:

Electric Utility

An increase in electric investments contributed to earnings for 2022. Timing of 2021 depreciation and other operations and maintenance costs contributed to higher earnings in 2021. Depreciation and operations and maintenance costs increased during the remainder of 2021 and into 2022 after significant capital projects were completed. The new customer information system went live in September 2021 and Badger Hollow I was completed in November 2021. MGE received approval to recover 100% AFUDC during construction of these projects.

Gas Utility

An increase in gas investments contributed to increased earnings for 2022. Higher gas retail sales resulting from colder weather in the first half of 2022 contributed to higher earnings for the nine months ended September 30, 2022. Heating degree days (a measure for determining the impact of weather during the heating season) increased by approximately 7% in the first nine months of 2022 compared to the same period in the prior year.

Transmission Investments

In September 2022, our share of ATC's earnings reflected an estimated possible loss of approximately $0.8 million, inclusive of interest and net of tax, related to the August 2022 developments in the MISO transmission owners complaints on authorized return on equity. See additional information in " Other Matters " below.

The following developments affected the first nine months of 2022:

2022/2023 Rate Settlement Agreement: In December 2021, the PSCW approved a settlement agreement for MGE's 2022 rate case. The settlement agreement provides for an 8.81% increase to electric rates and a 2.15% increase to gas rates for 2022. As part of that settlement agreement, the PSCW approved a 0.96% increase in 2023 gas rates and a potential 2023 electric rate change to be addressed through a limited rate case reopener. See " Other Matters " below for additional information on the 2022/2023 rate case settlement.

Utility Solar: Large solar generation projects were recently completed or are under construction, as shown in the following table. Incurred costs are reflected in "Property, plant, and equipment, net" for projects placed in service, or "Construction work in progress" for projects under construction on the consolidated balance sheets.


Project	Ownership Interest	Share of Generation	Share of Estimated Costs (a)	Costs Incurred as of September 30, 2022 (a)	Estimated Date of Commercial Operation
Red Barn	10%	9.16MW	$18 million	$0.6 million	Early 2023
Badger Hollow II	33%	50 MW	$76 million	$46.8 million (b)(c)	First Half of 2023
Paris	10%	31 MW	$51 million	$21.8 million (b)	2023 (d)

(a)

Excluding AFUDC.

(b)

MGE received specific approval to recover 100% AFUDC on Badger Hollow II and Paris. After tax, MGE recognized $1.9 million and $0.3 million of AFUDC equity through September 30, 2022, on Badger Hollow II and Paris, respectively, during construction. AFUDC has been excluded from the costs incurred in the table above.

(c)

Deferred Fuel Costs: MGE has under-recovered fuel costs through the nine months ended September 30, 2022. As of September 30, 2022, MGE had deferred $4.4 million of 2022 fuel costs. Coal transportation constraints resulted in reduced generation at Columbia, which required MGE to purchase power in the market at higher cost. We may continue to see increased fuel costs in the near term because of these coal transportation constraints. These costs will be subject to the PSCW's annual review of 2022 fuel costs, expected to be completed during 2023. See Footnote 9.b. of the Notes to Consolidated Financial Statements in this Report for further information regarding fuel cost proceedings.

In the near term, several items may affect us, including:

2021 Annual Fuel Proceeding: MGE under-recovered fuel costs in 2021. As of December 31, 2021, MGE had deferred $3.3 million of 2021 fuel costs. In August 2022, the PSCW issued a final decision in the 2021 fuel rules proceedings for MGE to include the recovery of these costs as part of the 2023 electric limited rate case reopener. There was no change to the costs to be recovered in the fuel rule proceedings from the amount MGE deferred in the previous year.

2023 Electric Limited Rate Case Reopener: In April 2022, MGE filed with the PSCW a proposed electric limited rate case reopener. The limited rate case reopener proposes a 4.38% increase to electric rates for 2023. See " Other Matters " below for additional information on the 2023 electric limited rate case reopener.

ATC Return on Equity: As discussed in " Other Matters " below, ATC's authorized ROE, which is used in calculating its rates and revenues, is the subject of a challenge before FERC. A decrease in ATC's ROE could result in lower equity earnings and distributions from ATC in the future. We derived approximately 5.1% and 5.7% of our net income during the nine months ended September 30, 2022 and 2021, respectively, from our investment in ATC.

Environmental Initiatives: There are proposed legislative rules and initiatives involving matters related to air emissions, water effluent, hazardous materials, and greenhouse gases, all of which affect generation plant capital expenditures and operating costs as well as future operational planning. Legislation and rulemaking addressing climate change and related matters could significantly affect the costs of owning and operating fossil-fueled generating plants. We would expect to seek and receive recovery of any such costs in rates. However, it is difficult to estimate the amount of such costs due to the uncertainty as to the timing and form of any legislation or rules, and the scope and time of the recovery of costs in rates, which may occur after those costs have been incurred and paid.

Future Generation – 80% carbon reduction target by 2030 (from 2005 levels): MGE has outlined initiatives to achieve our raised target.

•

Transitioning away from coal. Columbia: In February 2021, MGE, along with the other plant co-owners, announced plans to retire the two-unit coal-fired Columbia generating plant near Portage, Wisconsin. MGE currently owns 19% of the facility. The co-owners initially intended to retire Unit 1 by the end of

2023 and Unit 2 by the end of 2024. In June 2022, the target retirement date for both Units was updated to June 2026 after consideration by the owners of supply chain disruptions impacting the completion dates of current and planned renewable generation projects and the impact of those delays upon energy supply availability, reliability and cost. The postponement is not expected to affect MGE's goal to achieve 80% carbon reduction by 2030. Final timing and retirement dates for Units 1 and 2 are subject to change depending on operational, regulatory, and other factors. MGE continues to evaluate additional investments to replace the generation from Columbia while maintaining electric service reliability. These investments include cost-effective, clean energy projects to help achieve MGE's carbon reduction goals.

Elm Road Units: In November 2021, MGE announced plans to end the use of coal as a primary fuel at the Elm Road Units and transition the plant to natural gas. MGE is a minority owner of Elm Road, owning 8.33%. The approximately 1,230 MW coal-fired plant is co-owned by WEC Energy Group, whose subsidiary serves as operator, and by WPPI Energy, Inc. Transition plans and costs will be subject to PSCW approval. MGE's remaining use of coal is expected to be further reduced as the Elm Road Units transition to natural gas. By the end of 2030, MGE expects coal to be used only as a backup fuel at the Elm Road Units. This transition will help MGE meet its 2030 carbon reduction goals. By 2035, MGE expects that the Elm Road Units will be fully transitioned away from coal, which will eliminate coal as an internal generation source for MGE.

•

Growing renewable generation. MGE is seeking to acquire a joint interest in several renewable generation projects. See the 2022-2025 capital expenditures forecast included under " Liquidity and Capital Resources " below for information on these projects.

•

Natural gas as a fuel source. West Riverside: MGE is seeking approval for a sale and purchase of ownership interest in West Riverside. See the 2022-2025 capital expenditures forecast included under " Liquidity and Capital Resources " below for information on West Riverside.

Solar Procurement Disruptions – Import Regulations: In June 2021, the U.S. Customs and Border Protection (CBP) issued a Withhold Release Order (WRO) against silica-based products made by Hoshine Silicon Industry Co. Ltd., a company located in China's Xinjiang Uyghur Autonomous Region. As a result of this WRO, CBP is holding many solar panels imported into the United States until importers can prove that the panels do not contain materials originating from this region. The Uyghur Forced Labor Protection Act, a federal law that became effective on June 21, 2022, further established that all goods mined, produced, or manufactured wholly or in part in Xinjiang or by certain defined entities are prohibited from U.S. importation. MGE is currently assessing the potential impact of these disruptions on current and future solar projects which may result in an increase in costs or delays in construction timelines. In the event that such disruptions cause costs to exceed the levels approved for specific projects, we expect to file a notification with the PSCW and expect to request recovery of any increases in MGE’s next rate proceeding.

Solar Procurement Disruptions – Solar Tariff Investigation: In March 2022, the U.S. Department of Commerce (USDOC) announced a solar tariff investigation on solar panels from four Southeast Asian countries. This investigation could result in additional tariffs on solar panels. In June 2022, the USDOC issued a 24-month exemption from tariffs for solar panel and module imports from these four countries. MGE is currently assessing the potential impact of these disruptions on current and future solar projects which may result in an increase in costs or delays in construction timelines. In the event that such disruptions cause costs to exceed the levels approved for specific projects, we expect to file a notification with the PSCW and expect to request recovery of any increases in MGE’s next rate proceeding.

COVID-19 Update: MGE Energy continues to provide safe and reliable service to our customers despite the challenges presented by the COVID-19 and its variants. We have operated continuously throughout the pandemic and suffered no material disruptions in service or employment. We continue to monitor potential disruptions or constraints in materials and supplies from key suppliers and as well as macroeconomic trends, such as inflation. We could experience increased costs and delays in our ability to perform certain maintenance and capital project activities. We cannot estimate with any degree of certainty the actual impact of COVID-19 and associated governmental regulations may have on future results of operations, financial position, and liquidity. See Item 1A. "Risk Factors" "Pandemic virus or diseases, including COVID-19, could have a material adverse effect on our business, financial condition and liquidity" in our 2021 Annual Report on Form 10-K for a description of risk.

The following discussion is based on the business segments as discussed in Footnote 14 of the Notes to Consolidated Financial Statements in this Report.

•

Rate changes. In December 2021, the PSCW authorized MGE to increase 2022 rates for retail electric customers by approximately 8.81%. Rates charged to retail customers during the three months ended September 30, 2022 were $7.8 million higher than those charged during the same period in the prior year. See Footnote 9 of the Notes to Consolidated Financial Statements in this Report for further information on rate increase. Any increase in rates associated with fuel or purchase power costs are generally offset in fuel and purchased power costs and do not have a significant impact on net income.

•

Sales to the market. Sales to the market typically occur when MGE has more generation and purchases in the MISO market than are needed for its customer demand. The excess electricity is then sold to other utilities or power marketers in the MISO market. During the three months ended September 30, 2022, sales were made at higher market prices and partially offset by decreased market volume compared to the same period in the prior year, reflecting a decrease in sales. The revenue generated from these sales is included in fuel rules monitored costs. See fuel rules discussion in Footnote 9 of the Notes to Consolidated Financial Statements.

•

Revenue subject to refund. For cost recovery mechanisms, any over-collection of revenues resulting from costs authorized to be collected from customers in rates exceeding actual costs is recorded as a reduction of revenue in the period incurred, as the over-collection is expected to be refunded to customers in a subsequent period. In the year the over-collection is refunded, rates are reduced and offset as revenue

subject to refund. There is no net income impact in the year the costs are refunded.

•

Residential volume. During the three months ended September 30, 2022, residential sales decreased by approximately 4% compared to the same period in the prior year. This decrease was driven by a shift in usage patterns reflecting a reduction in remote work associated with the COVID-19 pandemic.

Electric fuel and purchased power


	Three Months Ended September 30,
(In millions)	2022		2021		$ Change
Fuel for electric generation	$	21.0	$	18.5	$	2.5
Purchased power		9.6		8.6		1.0

The $2.5 million increase in fuel for electric generation was due to an approximately 29% increase in the average cost offset by an approximately 12% decrease in internal generation. Coal transportation constraints resulted in reduced generation at Columbia, which required MGE to purchase power in the market at higher cost.

The $1.0 million increase in purchased power was due to an approximately 40% increase in market purchases as a result of lower internal generation.

Fuel and purchased power costs are generally offset by electric revenue and do not have a significant impact on net income. MGE expects to seek and receive recovery of fuel and purchased power costs outside the fuel rules bandwidth in customer rates. See Footnote 9 of the Notes to Consolidated Financial Statements in this Report for further information on the fuel rules bandwidth.

Gas deliveries and revenues

The following table compares MGE's gas revenues and gas therms delivered by customer class for each of the periods indicated:

The average retail rate per therm for the three months ended 2022, increased approximately 19% compared to 2021, reflecting a $5.7 million increase in natural gas commodity costs (recovered through the PGA).

•

Volume. For 2022, retail gas deliveries increased approximately 6% compared to the same period in the prior year primarily related to favorable weather conditions in September 2022.

Cost of gas sold

A $5.7 million increase in cost of gas sold driven by higher cost per therm of gas. Average cost per therm increased approximately 62%. MGE recovers the cost of natural gas in its gas segment through the PGA as described under gas deliveries and revenue above.

Consolidated operations and maintenance expenses

During the three months ended September 30, 2022, operations and maintenance expenses increased $0.7 million, compared to the same period in the prior year. The following contributed to the net change:


(In millions)
Increased customer accounts costs	$	0.5
Increased electric production expenses		0.4
Increased transmission costs		0.3
Decreased other expenses		(0.5	)
Total	$	0.7

Consolidated depreciation expense

Electric depreciation expense increased $1.7 million and gas depreciation expense increased $0.7 million during the three months ended September 30, 2022, compared to the same period in the prior year. MGE placed Badger Hollow I in service in November 2021. The timing of the in-service date contributed to the increase in electric depreciation expense. The new customer information system went live in September 2021, which increased depreciation expense for both electric and gas in 2022.

Nonregulated Energy Operations - MGE Energy and MGE

The nonregulated energy operations are conducted through MGE Energy's subsidiaries: MGE Power Elm Road (the Elm Road Units) and MGE Power West Campus (WCCF), which have been formed to own and lease electric generating capacity to assist MGE. During the three months ended September 30, 2022 and 2021, net income at the nonregulated energy operations segment was $5.6 million and $5.4 million, respectively.

Transmission Investment Operations - MGE Energy

The transmission investment segment holds our interest in ATC and ATC Holdco, and its income reflects our equity in the earnings of those investments. ATC Holdco was formed in December 2016 to pursue transmission development opportunities that typically have long development and investment lead times before becoming operational. ATC Holdco's transmission development activities have been suspended for the near term. During the three months ended September 30, 2022 and 2021, other income at the transmission investment segment primarily reflects ATC's operations and was $1.5 million and $2.5 million, respectively. In August 2022, the U.S. Court of Appeals for the D.C. Circuit vacated the underlying FERC orders regarding methodology for setting authorized return on equity resulting in an additional estimated possible loss. See Footnote 3 of the Notes to Consolidated Financial Statements in this Report and " Other Matters " below for additional information concerning ATC and summarized financial information regarding ATC.

Consolidated Income Taxes - MGE Energy and MGE

In 2022, the effective electric tax rate increased as a result of the return of electric excess deferred taxes related to the 2017 Tax Act not governed by IRS normalization rules in 2021. These costs were recorded as a regulatory liability in the year of remeasurement. See Footnote 4 of the Notes to Consolidated Financial Statements in this Report for the effective tax rate reconciliation.

Noncontrolling Interest, Net of Tax - MGE

Noncontrolling interest, net of tax, reflects the accounting required for MGE Energy's interest in MGE Power Elm Road (the Elm Road Units) and MGE Power West Campus (WCCF). MGE Energy owns 100% of MGE Power Elm Road and MGE Power West Campus. They are not owned by MGE. Due to the contractual agreements for these projects with MGE, the entities are considered VIEs with respect to MGE and their results are consolidated with those of MGE, the primary beneficiary of the VIEs. The following table shows MGE Energy's noncontrolling interest, net of tax, reflected on MGE's consolidated statement of income:

Rate changes. In December 2021, the PSCW authorized MGE to increase 2022 rates for retail gas customers by approximately 2.15%.

MGE recovers the cost of natural gas in its gas segment through the purchased gas adjustment clause (PGA). Under the PGA, MGE is able to pass through to its gas customers the cost of gas. Changes in PGA recoveries affect revenues but do not change net income in view of the pass-through treatment of the costs. Payments for natural gas increased driving higher rates during the nine months ended September 30, 2022.

The average retail rate per therm for the nine months ended 2022, increased approximately 26% compared to 2021, reflecting a $42.9 million increase in natural gas commodity costs (recovered through the PGA).

•

Volume. For 2022, retail gas deliveries increased approximately 13% compared to the same period in the prior year primarily related to favorable weather conditions in the current year.

•

Other. Other revenues increased primarily related to increase in gas customers in 2022 increasing revenue recorded for fixed customer charge compared to the same period in the prior year.

Cost of gas sold

The $42.9 million increase in cost of gas sold was driven by higher cost per therm of gas. Average cost per therm increased approximately 56%. An increase in volume of approximately 12% also contributed to the increase in cost. MGE recovers the cost of natural gas in its gas segment through the PGA as described under gas deliveries and revenue above.

Consolidated operations and maintenance expenses

During the nine months ended September 30, 2022, operations and maintenance expenses increased $6.1 million, compared to the same period in the prior year. The following contributed to the net change:

Increased administration and general costs are primarily related to increase in pension and OPEB service costs.

•

Increased customer accounts costs are related to increased costs associated with the new customer information system, which went live in September 2021.

•

Decreased electric production expenses are primarily related to lower Columbia costs. A $2.6 million additional expense was recorded in 2021 for Columbia inventory obsolescence and employee severance reserves associated with the Columbia retirement. MGE expects to request PSCW approval for regulatory recovery of these costs at a future date. The decrease in costs is offset by increased maintenance costs for Blount, Saratoga, Two Creeks, and Badger Hollow I.

Consolidated depreciation expense

Electric depreciation expense increased $5.7 million and gas depreciation expense increased $2.2 million during the nine months ended September 30, 2022, compared to the same period in the prior year. MGE placed Badger Hollow I in service in November 2021. The timing of the in-service date contributed to the increase in electric depreciation expense.

Cash Flows

The following summarizes cash flows for MGE Energy and MGE during the nine months ended September 30, 2022 and 2021:


	MGE Energy				MGE
(In thousands)	2022		2021		2022		2021
Cash provided by (used for):
Operating activities	$	144,282	$	141,297	$	141,786	$	135,451
Investing activities		(137,219)		(118,347)		(134,089)		(115,591)
Financing activities		(12,663)		1,656		(8,400)		31,930

Cash Provided by Operating Activities

MGE Energy

MGE Energy's consolidated net cash provided by operating activities is derived mainly from the electric and gas operations of its principal subsidiary, MGE.

Cash provided by operating activities during the nine months ended September 30, 2022, was $144.3 million, an increase of $3.0 million when compared to the same period in the prior year.

MGE Energy's net income decreased $2.8 million during the nine months ended September 30, 2022, when compared to the same period in the prior year.

MGE Energy's federal and state taxes paid decreased $3.0 million during the nine months ended September 30, 2022, when compared to the prior year.

Working capital accounts (excluding prepaid and accrued taxes) resulted in $17.7 million in cash used for operating activities during the nine months ended September 30, 2022. Working capital accounts were impacted by increased gas inventory driven by the increase in cost of gas and decreased other current liabilities, partially offset by decreased unbilled revenues.

Working capital accounts (excluding prepaid and accrued taxes) resulted in $9.1 million in cash used for operating activities during the nine months ended September 30, 2021. Actual purchased gas costs were $6.3 million higher than the amount collected in rates primarily due to the extreme cold weather experienced in the U.S. in February 2021. These costs were deferred as a regulatory asset and recovered throughout 2021. In addition, working capital accounts were impacted by increased accounts receivable and increased inventories, partially offset by increased other current liabilities, decreased unbilled revenues, and increased accounts payable.

Hosted software asset expenditures during the nine months ended September 30, 2022, were $0.5 million. This amount represents a decrease of $2.5 million of cash used when compared to the prior year.

MGE

Cash provided by operating activities during the nine months ended September 30, 2022, was $141.8 million, an increase of $6.3 million when compared to the same period in the prior year.

Net income decreased $3.0 million during the nine months ended September 30, 2022, when compared to the same period in the prior year.

MGE's federal and state taxes paid decreased $4.2 million during the nine months ended September 30, 2022, when compared to the prior year.

Working capital accounts (excluding prepaid and accrued taxes) resulted in $15.3 million in cash used for operating activities during the nine months ended September 30, 2022. Working capital accounts were impacted by increased gas inventory driven by the increase in cost of gas and decreased current liabilities, partially offset by decreased unbilled revenues.

Hosted software asset expenditures during the nine months ended September 30, 2022, were $0.5 million. This amount represents a decrease of $2.5 million of cash used when compared to the prior year.

Capital Requirements and Investing Activities

MGE Energy

MGE Energy's cash used for investing activities increased $18.9 million during the nine months ended September 30, 2022, when compared to the same period in the prior year.

Capital expenditures during the nine months ended September 30, 2022, were $133.4 million. This amount represents an increase of $19.3 million from the expenditures made in the same period in the prior year. This increase primarily reflects the increase of expenditures for Badger Hollow II and Paris.

Proceeds from the sale of investments decreased $0.8 million during the nine months ended September 30, 2022, when compared to the same period in the prior year.

MGE

MGE's cash used for investing activities increased $18.5 million during the nine months ended September 30, 2022, when compared to the same period in the prior year.

Capita l Expenditures

The following table shows MGE Energy's forecasted capital expenditures for 2022 through 2025:


	Forecasted
(In thousands)	2022 (a)		2023		2024		2025
Electric	$	138,200	$	181,000	$	185,100	$	174,400
Gas		25,300		26,200		25,600		23,200
Utility plant total		163,500		207,200		210,700		197,600
Nonregulated		7,700		7,900		7,800		6,100
MGE Energy total	$	171,200	$	215,100	$	218,500	$	203,700

(a)

Includes actual capital expenditures already incurred in 2022 and estimated capital expenditures for the remainder of the year.

Forecasted capital expenditures are based upon management's assumptions with respect to future events, including the timing and amount of expenditures associated with environmental compliance initiatives, legislative and regulatory action, supply chain and market disruptions, customer demand and support for electrification and renewable energy resources, energy conservation programs, load growth, the timing of any required regulatory approvals, and the adequacy of rate recovery. Actual events may differ materially from these assumptions and result in material changes to those forecasted amounts.

MGE is targeting at least 80% carbon reduction from electric generation by 2030 (from 2005 levels) and net-zero carbon electricity by 2050. Solar, wind, and battery storage projects are a major step toward deep decarbonization and greater use of clean energy sources in pursuit of our goal. MGE continues to evaluate solar, wind, and battery

storage projects that align with its goals as legacy fossil fuel-fired facilities are retired. The target early retirement date for Columbia is June 2026. MGE has included forecasted capital expenditures for the years 2022 through 2025 for projects to replace Columbia's generation. Additional replacement capital expenditures are expected to continue beyond 2025.

Our forecasted capital expenditures reflect the following significant renewable projects that are proposed or currently under construction:


Project	Source	Ownership Interest	Share of Generation/ Battery Storage	Share of Estimated Costs (c)	Estimated Date of Commercial Operation
Red Barn (a)	Wind	10%	9.16MW	$18 million (e)	Early 2023
Badger Hollow II (a)	Solar	33%	50 MW	$76 million (d)(e)	First Half of 2023
Paris (a)	Solar/Battery	10%	31 MW	$51 million (d)(e)	2023 (f)
Darien (b)	Solar/Battery	10%	25MW/7.5MW	$45 million (d)	2024 (f)
Koshkonong (b)	Solar/Battery	10%	30MW/16.5MW	$65 million (d)	2025 (f)

(a)

Approved by the PSCW.

(b)

Pending approval by the PSCW. There is no certainty that this project will be approved by the PSCW.

(c)

Excluding AFUDC.

(d)

Requested, in the case of projects pending PSCW approval, or received, in the case of Badger Hollow II and Paris, approval to recover 100% AFUDC.

(e)

See Footnote 12 of Notes to Consolidated Financial Statements in the Report for information on costs incurred.

(f)

Battery storage timing to be determined.

In 2022, MGE notified the PSCW of increases in projected costs at Badger Hollow II and Paris. The main drivers were increases in the costs of key commodities, labor, and solar modules resulting from supply chain and market disruptions. See Footnote 12 of Notes to Consolidated Financial Statements in this Report for more information on these projects. Furthermore, solar procurement disruptions have also shifted construction timelines for Darien and Koshkonong. Projected completion dates of these projects are one year later than originally anticipated. MGE continues to assess the potential impact of these disruptions on current and future solar projects which may result in an increase in costs or delays in construction timelines. See further information on procurement disruptions discussed earlier under "Executive Overview."

West Riverside: In 2016, MGE entered into an agreement with WPL under which MGE may acquire up to 50 MW of capacity in a gas-fired generating plant constructed by WPL at its West Riverside Energy Center in Beloit, Wisconsin, during the five-year period following the in-service date of the plant. The plant was placed in service in May 2020. In January 2022, MGE, along with joint applicants, filed an application with the PSCW requesting approval for a sale and purchase of ownership interests in West Riverside. If approved, MGE's share of West Riverside will be 25 MW at a purchase price of approximately $25 million. The closing and actual transfer of ownership is expected to occur in March 2023. MGE also retains the option to purchase an additional 25 MW of capacity from West Riverside until May 2025. MGE currently expects to exercise this option in a future period.

Electric and Gas Distribution: In 2022 through 2025, electric and gas capital expenditures include investment in enhanced metering solutions to provide customers with more timely and detailed energy use information. Investments in advanced metering infrastructure will provide additional benefits including outage and demand response and automated meter reading capabilities. Forecasted capital expenditures in those years is approximately $24 million.

Cash Used for/Provided by Financing Activities

MGE Energy

Cash used for MGE Energy's financing activities was $12.7 million during the nine months ended September 30, 2022, compared to cash proceeds of $1.7 million for the same period in the prior year.

During the nine months ended September 30, 2022, dividends paid were $42.8 million compared to $40.8 million in the prior year. The increase reflected a higher dividend rate per share ($1.183 vs. $1.128).

During the nine months ended September 30, 2021, MGE borrowed $100.0 million of senior unsecured notes which was used to assist with financing additional capital expenditures and other corporate obligations. There were no long-term debt borrowings during the nine months ended September 30, 2022.

During the nine months ended September 30, 2022, net short-term debt borrowings were $34.5 million, compared to $52.5 million of repayments in the same period in the prior year.

MGE

During the nine months ended September 30, 2022, cash used for MGE's financing activities was $8.4 million, compared to cash proceeds of $31.9 million for the same period in the prior year.

Cash dividends to parent (MGE Energy) were $21.0 million during the nine months ended September 30, 2022. There were no cash dividends to parent in the same period in the prior year.

Distributions to parent from noncontrolling interest, which represent distributions from MGE Power Elm Road and MGE Power West Campus to MGE Energy, were $17.5 million during the nine months ended September 30, 2022, compared to $10.5 million in the same period in the prior year.

During the nine months ended September 30, 2022, net short-term debt borrowings were $34.5 million, compared to $52.5 million of repayments in the same period in the prior year.

Capitalization Ratios

MGE Energy's capitalization ratios were as follows:


	MGE Energy
	September 30, 2022	December 31, 2021
Common shareholders' equity	62.1%	62.2%
Long-term debt (a)	35.6%	37.5%
Short-term debt	2.3%	0.3%

(a)

Includes the current portion of long-term debt.

Credit Ratings

MGE Energy's and MGE's access to the capital markets, including, in the case of MGE, the commercial paper market, and their respective financing costs in those markets, may depend on the credit ratings of the entity that is accessing the capital markets.

None of MGE Energy's or MGE's borrowing is subject to default or prepayment as a result of a downgrading of credit ratings, although a downgrading of MGE's credit ratings would increase fees and interest charges under both MGE Energy's and MGE's credit agreements.

Environmental Matters

See the discussion of environmental matters included in the 2021 Annual Report on Form 10-K , as updated by Footnote 8.a. of Notes to Consolidated Financial Statements in this Report.

Othe r Matters

Rate Matters

In December 2021, the PSCW approved a settlement agreement for MGE's 2022 rate case. The settlement agreement provides for an 8.81% increase to electric rates and a 2.15% increase to gas rates for 2022. As part of that settlement agreement, the PSCW approved a 0.96% increase in 2023 gas rates and a potential 2023 electric rate change to be addressed through a limited rate case reopener.

In April 2022, MGE filed with the PSCW a limited rate reopener proposing a 4.38% increase to electric rates for 2023.

Details related to MGE's 2022/2023 approved settlement agreement and pending electric limited reopener:


(Dollars in thousands)	Authorized Average Rate Base (a)		Authorized Average CWIP (b)		Authorized Return on Common Equity (c)	Common Equity Component of Regulatory Capital Structure	Effective Date
Electric (2022 Test Period)	$	1,044,362	$	19,976	9.8%	55.63%	1/1/2022
Gas (2022 Test Period)	$	299,319	$	11,410	9.8%	55.63%	1/1/2022
Electric (2023 Test Period) (d)	$	1,159,155	$	19,976	9.8%	55.63%	1/1/2023
Gas (2023 Test Period)	$	312,270	$	8,228	9.8%	55.63%	1/1/2023

(a)

Average rate base amounts reflect MGE's allocated share of rate base and do not include construction work in progress (CWIP) or a cash working capital allowance and were calculated using a forecasted 13-month average for the test periods. The PSCW provides a return on selected CWIP and a cash working capital allowance by adjusting the percentage return on rate base.

(b)

50% of the forecasted 13-month average CWIP for the test periods which earns an AFUDC return. Projects eligible to earn 100% AFUDC are excluded from this balance and discussed further in the Management Discussion and Analysis of Financial Condition and Results of Operations - Executive Overview section.

(c)

Authorized returns on common equity may not be indicative of actual returns earned or projections of future returns, as actual returns will be affected by the volume of electricity or gas sold.

(d)

Pending approval by the PSCW.

See Footnote 9 of Notes to Consolidated Financial Statements in this Report for further discussion of rate proceedings.

ATC

MISO transmission owners, including ATC, are involved in two complaints filed at FERC by several parties challenging that the base ROE in effect for MISO transmission owners, including ATC, was no longer just and reasonable. Each complaint provided for a 15-month statutory refund period: November 12, 2013 through February 11, 2015 (the "First Complaint Period") and February 12, 2015 through May 11, 2016 (the "Second Complaint Period").

In May 2020, FERC issued an order further refining the methodology for setting authorized ROE. This refined methodology increased the authorized ROE from 9.88% to 10.02%. This base ROE is effective for the First Complaint Period and for all periods following September 2016. This order also dismissed the second complaint. Accordingly, no refunds were ordered for the Second Complaint Period.

As a result of the May 2020 FERC order, our share of ATC's earnings reflected a $0.6 million reduction of our reserve. Additionally, our share of ATC's earnings reflected the derecognition of a possible refund related to the Second Complaint Period as ATC considered such a refund to be no longer probable. However, due to pending requests for rehearing, a loss related to the 2015 complaint remains possible. Our share of the estimated refund for the Second Complaint Period is approximately $2.3 million. MGE has not recorded a possible loss for the Second Complaint Period.

Several petitions for review of FERC’s prior orders were filed with the U.S. Court of Appeals for the D.C. Circuit (the "Court") and an oral argument was held in November 2021. In August 2022, the Court ruled that four of the five

arguments made by the complaining parties were unpersuasive. However, the Court agreed that FERC’s decision to reintroduce a risk-premium model into its ROE methodology was arbitrary and capricious. The Court vacated the underlying orders for the First Complaint Period and remanded to FERC for further proceedings. In September 2022, our share of ATC's earnings reflected an estimated possible loss of approximately $0.8 million, inclusive of interest and net of tax, for a possible additional refund for the First Complaint Period and for the period following the Second Complaint Period. Although the Court agreed that FERC was correct to use the base ROE established in the first complaint to adjudicate the second, and that FERC was right to dismiss the second complaint, the second complaint was also remanded for FERC to reopen proceedings. Any reduction in ATC's ROE could result in lower equity earnings and distributions from ATC in the future.

We derived approximately 5.1% and 5.7% of our net income during the nine months ended September 30, 2022 and 2021, respectively, from our investment in ATC.

Inflation Reduction Act

In August 2022, the Inflation Reduction Act (IRA) was signed into law. Among other provisions, the IRA: extends current PTC and ITC for renewable technologies (e.g., wind and solar); restores full value of the PTC and ITC for qualifying facilities placed into service after 2021 that satisfy prevailing wage and apprenticeship requirements; creates a PTC for solar, clean hydrogen and nuclear; establishes an ITC for energy storage, microgrids, and interconnection facilities; and allows companies to monetize or sell credits to unrelated parties. In addition, the IRA created a new corporate alternative minimum tax (AMT). MGE Energy does not expect to be subject to the AMT in the near term. Implementation of IRA provisions is subject to the issuance of additional guidance by the U.S. Treasury Department. While the final impact cannot be determined at this time, the IRA is not expected to have a material impact on MGE Energy and MGE for the year ending December 31, 2022.

Adoption of Accounting Principles and Recently Issued Accounting Pronouncements

See Footnote 2 of Notes to Consolidated Financial Statements in this Report for discussion of new accounting pronouncements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

There were no material changes to the market risks disclosed in Item 7A. Quantitative and Qualitative Disclosures About Market Risk in our 2021 Annual Report on Form 10-K , except as noted below.

Equity Price Risk - Pension-Related Assets

MGE currently funds its liabilities related to employee benefits through trust funds. These funds, which include investments in debt and equity securities, are managed by various third-party investment managers. Changes in the market value of these investments can have an impact on the future expenses related to these liabilities. The value of employee benefit plan assets has declined by approximately 23% during the nine months ended September 30, 2022.

Item 4. Controls and Procedures.

During the third quarter of 2022, each registrant's management, including the principal executive officer and principal financial officer, evaluated its disclosure controls and procedures related to the recording, processing, summarization, and reporting of information in its periodic reports that it files with the SEC. These disclosure controls and procedures have been designed to ensure that material information relating to that registrant, including its subsidiaries, is accumulated and made known to that registrant's management, including these officers, by other employees of that registrant and its subsidiaries as appropriate to allow timely decisions regarding required disclosure, and that this information is recorded, processed, summarized, evaluated, and reported, as applicable, within the time periods specified in the SEC's rules and forms. The evaluations take into account changes in the internal and external operating environments that may impact those controls and procedures. Due to the inherent limitations of control systems, not all misstatements may be detected. These inherent limitations include the realities that judgments in decision making can be faulty and breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. Also, MGE Energy does not control or manage certain of its unconsolidated entities and thus, its access and ability to apply its procedures to those entities is more limited than is the case for its consolidated subsidiaries.

As of September 30, 2022, each registrant's principal executive officer and principal financial officer concluded that its disclosure controls and procedures were effective. Each registrant intends to strive continually to improve its disclosure controls and procedures to enhance the quality of its financial reporting.

During the quarter ended September 30, 2022, there were no changes in either registrant's internal controls over financial reporting that materially affected, or are reasonably likely to affect materially, that registrant's internal control over financial reporting.

PART II. O THER INFORMATION.

None.

Item 4. Mine Sa fety Disclosures.

Not applicable to MGE Energy and MGE.

Item 5. Other Inf ormation.

Expected Issuance of Notes

On November 1, 2022, MGE entered into a private placement Note Purchase Agreement in which it committed to issue $25 million of 5.43% senior notes, Series A, due December 1, 2032, $15 million of 5.43% senior notes, Series B, due February 15, 2033, and $35 million of 5.53% senior notes, Series C, due February 15, 2035. Funding will occur on December 1, 2022 for Series A notes and on February 28, 2023 for Series B notes and Series C notes. The proceeds of the notes will be used to assist with capital expenditures and other corporate obligations.

The Series A, Series B, and Series C notes are redeemable at any time at MGE's option at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued interest to the redemption date and a make-whole premium (not less than zero) equal to the excess, if any, of the discounted present value of the remaining scheduled payments of principal and interest on the notes to be redeemed over the principal amount of the notes to be redeemed, except that no make-whole premium is due on a note that is redeemed during the 90-day period immediately preceding and ending on its maturity date. Following a change in control event, MGE must offer to prepay the notes at a price equal to 100% of the principal amount of the notes, plus accrued interest to the date of prepayment, but without any make-whole premium. The prepayment offer expires if not accepted by a holder of notes within a defined period. A change in control event is deemed to have occurred if MGE does not have an investment grade rating for its senior, unsecured, long-term indebtedness from at least two of Standard & Poor's Rating Services, Moody's Investors Service or any other nationally recognized statistical rating agency, within 90 days after an acquisition of beneficial ownership of 30% or more of the outstanding voting stock of MGE Energy, Inc. by one person, or two or more persons acting in concert.

Events of default under the Note Purchase Agreement include failures to pay principal, make-whole premium or interest on the notes; defaults in the performance of various covenants; cross-defaults to specified other indebtedness; failure to pay specified judgments; and certain bankruptcy-related events; subject to any applicable cure periods. The Note Purchase Agreement requires MGE to maintain a ratio of its consolidated indebtedness to consolidated total capitalization not to exceed a maximum of 65%. Both consolidated indebtedness and consolidated total capitalization are determined in accordance with generally accepted accounting principles, except that amounts included within MGE's indebtedness and capitalization from "variable interest entities" as a result of the application of FASB Interpretation No. 46, Consolidation of Variable Interest Entities – an Interpretation of ARB No. 51, as modified, are excluded.

The Note Purchase Agreement also restricts MGE from issuing "Priority Debt" in an amount exceeding 20% of its consolidated assets. MGE has agreed not to use the capacity to issue Priority Debt to grant a lien to secure its principal credit facility indebtedness without simultaneously providing that the notes be equally and ratably secured with the principal credit facility indebtedness so long as such indebtedness is so secured. Priority Debt is defined as any indebtedness of MGE secured by liens other than specified liens permitted by the Note Purchase Agreement and certain unsecured indebtedness of certain subsidiaries. Principal credit facility indebtedness means the indebtedness under MGE's Amended and Restated Credit Agreements dated as of February 7, 2019, with the lenders party thereto and JPMorgan Chase Bank, N.A., as Administrative Agent, and with the lenders party thereto and US Bank National Association, as Administrative Agent, or, in each case, any replacement credit agreement, including amendments and restatements.
