ALLETE, Inc. 2021 Form 10-K 6 Item 1. Business Overview. Part I ALLETE is a leader in the nation’s clean-energy transformation. Our businesses and dedicated employees deliver sustainable energy solutions that mitigate climate change, build thriving communities, help customers reach their sustainability goals and drive value for shareholders. ALLETE’s largest business, Minnesota Power, recently reached a milestone of providing 50 percent renewable energy, and envisions delivering 100 percent carbon-free energy to customers by 2050—a vision grounded in a steadfast commitment to climate, customers and community through its EnergyForward strategy. ALLETE Clean Energy, our second-largest business, is positioned at the heart of society’s clean-energy transformation and owns, operates and is developing more than 1,300 megawatts of wind energy generation across eight states – helping some of the largest companies in the country reduce their carbon footprint. In February 2021, Minnesota Power filed its latest IRP with the MPUC, which outlines its clean-energy transition plans through 2035. These plans include expanding its renewable energy supply to 70 percent by 2030, achieving coal-free operations at its facilities by 2035, and investing in a resilient and flexible transmission and distribution grid. Minnesota Power has also set a target to achieve an 80 percent reduction in carbon emissions by 2035 compared to 2005 levels. As part of these plans, Minnesota Power anticipates adding approximately 400 MW of new wind and solar energy resources, retiring Boswell Unit 3 by 2030 and transforming Boswell Unit 4 to be coal-free by 2035. Minnesota Power’s plans recognize that advances in technology will play a significant role in completing its transition to carbon-free energy supply, reliably and affordably. A final decision on the IRP is expected in second half of 2022. In recent years, Minnesota Power has transformed its energy supply from more than a 95 percent reliance on coal to become a leader in the nation’s clean- energy transformation. Since 2013, the company has closed or converted seven of its nine coal-fired units and added nearly 900 megawatts of renewable energy sources. Additionally, Minnesota Power has been a leader in energy conservation, surpassing the state’s conservation goals each year for the past decade. ALLETE is also committed to earning a financial return that rewards our shareholders, allows for reinvestment in our businesses, and sustains growth. ALLETE is predominately a regulated utility through Minnesota Power, SWL&P, and an investment in ATC. ALLETE’s strategy is to remain predominately a regulated utility while also investing in ALLETE Clean Energy and our Corporate and Other businesses to complement its regulated businesses, balance exposure to the utility’s industrial customers, and provide potential long-term earnings growth. The ongoing COVID-19 pandemic has resulted in widespread impacts on the global economy and on our employees, customers, contractors, and suppliers. There is considerable uncertainty regarding the length of time for which COVID-19 will continue, if new variants will emerge or the extent and duration of measures to try to contain the virus. Additional disclosures in this Form 10-K regarding the impacts of the ongoing COVID-19 pandemic are located in Item 1A. Risk Factors and Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations. Regulated Operations includes our regulated utilities, Minnesota Power and SWL&P, as well as our investment in ATC, a Wisconsin-based regulated utility that owns and maintains electric transmission assets in portions of Wisconsin, Michigan, Minnesota and Illinois. Minnesota Power provides regulated utility electric service in northeastern Minnesota to approximately 150,000 retail customers. Minnesota Power also has 15 non-affiliated municipal customers in Minnesota. SWL&P is a Wisconsin utility and a wholesale customer of Minnesota Power. SWL&P provides regulated utility electric, natural gas and water service in northwestern Wisconsin to approximately 15,000 electric customers, 13,000 natural gas customers and 10,000 water customers. Our regulated utility operations include retail and wholesale activities under the jurisdiction of state and federal regulatory authorities. (See Note 4. Regulatory Matters.) ALLETE Clean Energy focuses on developing, acquiring, and operating clean and renewable energy projects. ALLETE Clean Energy currently owns and operates, in seven states, more than 1,300 MW of nameplate capacity wind energy generation that is contracted under PSAs of various durations. In addition, ALLETE Clean Energy currently has approximately 200 MW of wind energy facilities under contract to be sold to others. ALLETE Clean Energy also engages in the development of wind energy facilities to operate under long-term PSAs or for sale to others upon completion. ALLETE, Inc. 2021 Form 10-K 7 Overview (Continued) U.S. Water Services provided integrated water management for industry by combining chemical, equipment, engineering and service for customized solutions to reduce water and energy usage, and improve efficiency.

In 2021, industrial customers represented 47 percent of total regulated utility kWh sales. Our industrial customers are primarily in the taconite mining, paper, pulp and secondary wood products, and pipeline industries. The ongoing COVID-19 pandemic and related governmental responses has led to a disruption of economic activity, and could result in an extended disruption of economic activity. This disruption resulted in reduced sales and revenue from industrial customers in 2020 as many industrial customers operated at reduced levels or were temporarily closed or idled during 2020. Sales to our industrial customers in 2021 were similar to levels prior to the COVID-19 pandemic; however, further disruption of economic activity or an extended disruption of economic activity may lead to additional adverse impacts on our industrial customers including reduced production or the temporary idling or indefinite shutdown of facilities, which would result in lower sales and revenue from these customers. Industrial Customer Kilowatt-hours Sold Year Ended December 31 Millions Taconite Paper, Pulp and Secondary Wood Products Pipelines and Other Industrial Total Industrial Customer Kilowatt-hours Sold 2021 5,281 702 1,213 7,196 % 73 10 17 100 2020 4,296 752 1,144 6,192 % 69 12 19 100 2019 5,039 1,014 1,224 7,277 % 69 14 17 100 Six taconite facilities served by Minnesota Power made up approximately 80 percent of 2020 iron ore pellet production in the U.S. according to data from the Minnesota Department of Revenue 2021 Mining Tax Guide. These taconite facilities were owned by Cliffs and USS Corporation at the end of the 2021. (See Large Power Customer Contracts.) Sales to taconite customers represented 5,281 million kWh, or 73 percent of total industrial customer kWh sales in 2021. Taconite, an iron‑bearing rock of relatively low iron content, is abundantly available in northern Minnesota and an important domestic source of raw material for the steel industry. Taconite processing plants use large quantities of electric power to grind the iron-bearing rock, and agglomerate and pelletize the iron particles into taconite pellets. Minnesota Power’s taconite customers are capable of producing approximately 41 million tons of taconite pellets annually. Taconite pellets produced in Minnesota are primarily shipped to North American steel making facilities that are part of the integrated steel industry, which continue to lead the world in environmental performance among steelmaking countries. According to the U.S. Department of Energy, steel production in the U.S. is the most energy efficient of any major steel producing country. Steel produced from these North American facilities is used primarily in the manufacture of automobiles, appliances, tubular applications for all industries, and in the construction industry. Steel is also a critical component of the clean energy transformation underway today. The demand for more renewable energy and the need for additional infrastructure to transport green energy from the point of generation to the end user both require steel. Historically, less than 10 percent of Minnesota taconite production has been exported outside of North America. ALLETE, Inc. 2021 Form 10-K 9 REGULATED OPERATIONS (Continued) Industrial Customers (Continued) There has been a general historical correlation between U.S. steel production and Minnesota taconite production. The American Iron and Steel Institute, an association of North American steel producers, reported that U.S. raw steel production operated at approximately 82 percent of capacity in 2021 (68 percent in 2020 and 80 percent in 2019). The World Steel Association, an association of steel producers, national and regional steel industry associations, and steel research institutes representing approximately 85 percent of world steel production, projected U.S. steel consumption in 2022 will increase by approximately 6 percent compared to 2021. The following table reflects Minnesota Power’s taconite customers’ production levels for the past ten years: Minnesota Power Taconite Customer Production Year 2021* 2020 2019 2018 2017 2016 2015 2014 2013 2012 Tons (Millions) 39 30 37 39 38 28 31 39 37 39 Source: Minnesota Department of Revenue 2021 Mining Tax Guide for years 2012 - 2020. * Preliminary data from the Minnesota Department of Revenue. Minnesota Power’s taconite customers may experience annual variations in production levels due to such factors as economic conditions, short-term demand changes or maintenance outages. We estimate that a one million ton change in Minnesota Power’s taconite customers’ production would impact our annual earnings per share by approximately $0.04, net of expected power marketing sales at current prices. Changes in wholesale electric prices or customer contractual demand nominations could impact this estimate. Minnesota Power proactively sells power in the wholesale power markets that is temporarily not required by industrial customers to optimize the value of its generating facilities. Long-term reductions in taconite production or a permanent shut down of a taconite customer may lead Minnesota Power to file a general rate case to recover lost revenue. In addition to serving the taconite industry, Minnesota Power serves a number of customers in the paper, pulp and secondary wood products industry, which represented 702 million kWh, or 10 percent of total industrial customer kWh sales in 2021. Minnesota Power also has an agreement to provide steam for one paper and pulp customer for use in the customer’s operations. The four major paper and pulp mills we serve reported operating at lower levels in 2021 compared to 2020. Verso Corporation indefinitely idled its paper mill in Duluth, Minnesota, which it subsequently sold to ST Paper in May 2021. (See Outlook – Regulated Operations – Industrial Customers and Prospective Additional Load – Paper, Pulp and Secondary Wood Products – Verso Corporation and ST Paper.) Large Power Customer Contracts. Minnesota Power had eight Large Power Customer contracts as of December 31, 2021, each serving requirements of 10 MW or more of customer load; however, Minnesota Power and Verso Corporation mutually agreed to resolve the outstanding commitments under the contract in January 2022. The customers as of December 31, 2021 consisted of six taconite facilities owned by Cliffs and USS Corporation as well as four paper and pulp mills. Certain facilities with common ownership are served under combined contracts. ALLETE, Inc. 2021 Form 10-K 10 REGULATED OPERATIONS (Continued) Large Power Customer Contracts (Continued) Large Power Customer contracts require Minnesota Power to have a certain amount of generating capacity available. In turn, each Large Power Customer is required to pay a minimum monthly demand charge that covers the fixed costs associated with having this capacity available to serve the customer, including a return on common equity. Most contracts allow customers to establish the level of megawatts subject to a demand charge on a three to four- month basis and require that a portion of their megawatt needs be committed on a take-or-pay basis for at least a portion of the term of the agreement. In addition to the demand charge, each Large Power Customer is billed an energy charge for each kWh used that recovers the variable costs incurred in generating electricity. Five of the Large Power Customer contracts have interruptible service which provides a discounted demand rate in exchange for the ability to interrupt the customers during system emergencies. Minnesota Power also provides incremental production service for customer demand levels above the contractual take-or-pay levels. There is no demand charge for this service and energy is priced at an increment above Minnesota Power’s cost. Incremental production service is interruptible. All contracts with Large Power Customers continue past the contract termination date unless the required advance notice of cancellation has been given. The required advance notice of cancellation varies from two to four years. Such contracts reduce the impact on earnings that otherwise would result from significant reductions in kWh sales to such customers. Large Power Customers are required to take all of their purchased electric service requirements from Minnesota Power for the duration of their contracts. The rates and corresponding revenue associated with capacity and energy provided under these contracts are subject to change through the same regulatory process governing all retail electric rates. (See Regulatory Matters – Electric Rates.) Minnesota Power, as permitted by the MPUC, requires its taconite-producing Large Power Customers to pay weekly for electric usage based on monthly energy usage estimates. These customers receive estimated bills or make weekly prepayments based on Minnesota Power’s estimate of the customer’s energy usage, forecasted energy prices and fuel adjustment clause estimates. Minnesota Power’s taconite‑producing Large Power Customers have generally predictable energy usage on a week-to-week basis and any differences that occur are trued-up the following month.

In 2021, residential and commercial customers represented 16 percent of total regulated utility kWh sales. Municipal Customers. In 2021, municipal customers represented 4 percent of total regulated utility kWh sales. Minnesota Power’s wholesale electric contracts with 15 non-affiliated municipal customers in Minnesota have termination dates ranging from 2024 through 2037, with a majority of contracts effective through 2029. Two of the wholesale contracts include a termination clause requiring a three-year notice to terminate. (See Note 4. Regulatory Matters.) Other Power Suppliers. The Company also enters into off-system sales with Other Power Suppliers. These sales are at market‑based prices into the MISO market on a daily basis or through bilateral agreements of various durations. Our PSAs are detailed in Note 8. Commitments, Guarantees and Contingencies, with additional disclosure provided in the following paragraphs. Basin PSAs. Minnesota Power had an agreement to sell 100 MW of capacity and energy to Basin for a ten-year period which expired in April 2020. Minnesota Power has two additional agreements to sell capacity to Basin at fixed prices. (See Note 8. Commitments, Guarantees and Contingencies.) Minnkota Power PSA. Minnesota Power has a PSA with Minnkota Power where Minnesota Power is selling a portion of its entitlement from Square Butte to Minnkota Power, resulting in Minnkota Power’s net entitlement increasing and Minnesota Power’s net entitlement decreasing until Minnesota Power’s share is eliminated at the end of 2025. Of Minnesota Power’s 50 percent output entitlement, it sold approximately 28 percent to Minnkota Power in 2021 (28 percent in 2020 and in 2019). Minnkota Power’s net entitlement increases to approximately 32 percent in 2022, 37 percent in 2023, 41 percent in 2024, 46 percent in 2025 and 50 percent in 2026. (See Power Supply – Long-Term Purchased Power.) Silver Bay Power PSA. In 2016, Minnesota Power and Silver Bay Power entered into a PSA through 2031. Silver Bay Power supplies approximately 90 MW of load to Northshore Mining, an affiliate of Silver Bay Power, which had previously been served predominately through self-generation by Silver Bay Power. Minnesota Power now supplies the full energy requirements for Silver Bay Power. Seasonality The operations of our industrial customers, which make up a large portion of our electric sales, are not typically subject to significant seasonal variations. (See Electric Sales / Customers.) As a result, Minnesota Power is generally not subject to significant seasonal fluctuations in electric sales; however, Minnesota Power and SWL&P electric and natural gas sales to other customers may be affected by seasonal differences in weather. In general, peak electric sales occur in the winter and summer months with fewer electric sales in the spring and fall months. Peak sales of natural gas generally occur in the winter months. Additionally, our regulated utilities have historically generated fewer sales and less revenue when weather conditions are milder in the winter and summer. Power Supply In order to meet its customers’ electric requirements, Minnesota Power utilizes a mix of its own generation and purchased power. As of December 31, 2021, approximately 50 percent of Minnesota Power’s power supply was provided by renewable energy sources. This was enabled by the completion of the 250 MW Nobles 2 wind energy facility in December 2020 and the GNTL in June 2020, which is used to deliver 250 MW of hydroelectric energy from Manitoba Hydro. Minnesota Power’s remaining operating coal-fired facilities are Boswell Units 3 and 4, which Minnesota Power proposed in its latest IRP to retire by 2030 and be coal-free by 2035, respectively. (See Regulatory Matters.) The following table reflects Minnesota Power’s generating capabilities as of December 31, 2021, and total electrical supply for 2021. Minnesota Power had an annual net peak load of 1,557 MW on July 26, 2021.

Minnesota Power purchases low-sulfur, sub-bituminous coal from the Powder River Basin region located in Montana and Wyoming. Coal consumption in 2021 for electric generation at Minnesota Power’s coal-fired generating stations was 2.7 million tons (2.2 million tons in 2020; 2.5 million tons in 2019). As of December 31, 2021, Minnesota Power had coal inventories of 0.4 million tons (0.8 million tons as of December 31, 2020). Minnesota Power has coal supply agreements providing for the purchase of a significant portion of its coal requirements through December 2022. In 2022, Minnesota Power expects to obtain coal under these coal supply agreements and in the spot market. Minnesota Power continues to explore other future coal supply options and believes that adequate supplies of low-sulfur, sub-bituminous coal will continue to be available. Minnesota Power also has coal transportation agreements in place for the delivery of a significant portion of its coal requirements through December 2024. The costs of fuel and related transportation costs for Minnesota Power’s generation are recoverable from Minnesota Power’s utility customers through the fuel adjustment clause. Coal Delivered to Minnesota Power Year Ended December 31 Average Price per Ton Average Price per MBtu 2021 $39.51 $2.18 2020 $34.94 $1.93 2019 $35.31 $1.94 Long-Term Purchased Power. Minnesota Power has contracts to purchase capacity and energy from various entities, including output from certain coal, wind, hydro and solar generating facilities. Our PPAs are detailed in Note 8. Commitments, Guarantees and Contingencies, with additional disclosure provided in the following paragraph. Square Butte PPA. Under the PPA with Square Butte that extends through 2026, Minnesota Power is entitled to 50 percent of the output of Square Butte’s 455 MW coal-fired generating unit. (See Note 8. Commitments, Guarantees and Contingencies.) BNI Energy mines and sells lignite coal to Square Butte. This lignite supply is sufficient to provide fuel for the anticipated useful life of the generating unit. Square Butte’s cost of lignite consumed in 2021 was approximately $1.94 per MBtu ($1.75 per MBtu in 2020; $1.88 per MBtu in 2019). (See Electric Sales / Customers – Minnkota Power PSA.) Manitoba Hydro. Minnesota Power has three long-term PPAs with Manitoba Hydro. Under the first PPA, Minnesota Power is purchasing surplus energy through April 2022. This energy-only agreement primarily consists of surplus hydro energy on Manitoba Hydro’s system that is delivered to Minnesota Power on a non-firm basis. Under this agreement, Minnesota Power will purchase at least one million MWh of energy over the contract term. The second PPA provides for Minnesota Power to purchase 250 MW of capacity and energy from Manitoba Hydro through May 2035. The third PPA provides for Minnesota Power to purchase up to 133 MW of energy from Manitoba Hydro through June 2040. Transmission and Distribution We have electric transmission and distribution lines of 500 kV (232 miles), 345 kV (241 miles), 250 kV (466 miles), 230 kV (715 miles), 161 kV (43 miles), 138 kV (130 miles), 115 kV (1,248 miles) and less than 115 kV (6,390 miles). We own and operate 159 substations with a total capacity of 10,086 megavoltamperes. Some of our transmission and distribution lines interconnect with other utilities. Great Northern Transmission Line. As a condition of the 250 MW long-term PPA entered into with Manitoba Hydro, construction of additional transmission capacity was required. As a result, Minnesota Power constructed the GNTL, an approximately 220‑mile 500-kV transmission line between Manitoba and Minnesota’s Iron Range that was proposed by Minnesota Power and Manitoba Hydro in order to strengthen the electric grid, enhance regional reliability and promote a greater exchange of sustainable energy. In June 2020, Minnesota Power placed the GNTL into service with project costs of approximately $310 million incurred by Minnesota Power. Total project costs, including those costs contributed by a subsidiary of Manitoba Hydro, totaled approximately $660 million. The 250 MW PPA with Manitoba Hydro commenced when the GNTL was placed into service. ALLETE, Inc. 2021 Form 10-K 14 REGULATED OPERATIONS (Continued) Investment in ATC Our wholly-owned subsidiary, ALLETE Transmission Holdings, owns approximately 8 percent of ATC, a Wisconsin-based utility that owns and maintains electric transmission assets in portions of Wisconsin, Michigan, Minnesota and Illinois. We account for our investment in ATC under the equity method of accounting. As of December 31 2021, our equity investment in ATC was $154.5 million ($149.0 million as of December 31, 2020). (See Note 5. Equity Investments.) ATC’s authorized return on equity is 10.02 percent, or 10.52 percent including an incentive adder for participation in a regional transmission organization, based on a 2020 FERC order that granted rehearing of a 2019 FERC order. These FERC orders are subject to various outstanding legal challenges related to the refund period ordered by the FERC. If these legal challenges are successful, ATC may be required to provide refunds to its customers of up to approximately $65 million of which our share would be approximately $5 million pre-tax. In addition, the FERC issued a Notice of Proposed Rulemaking in April 2021 proposing to limit the 50 basis point incentive adder for participation in a regional transmission organization to only the first three years of membership in such an organization. If this proposal is adopted, our equity in earnings from ATC would be reduced by approximately $1 million pre-tax annually. ATC’s 10-year transmission assessment, which covers the years 2021 through 2030, identifies a need for between $3.5 billion and $4.2 billion in transmission system investments. These investments by ATC, if undertaken, are expected to be funded through a combination of internally generated cash, debt and investor contributions. As opportunities arise, we plan to make additional investments in ATC through general capital calls based upon our pro rata ownership interest in ATC. Properties Our Regulated Operations businesses own office and service buildings, an energy control center, repair shops, electric plants, transmission facilities and storerooms in various localities in Minnesota, Wisconsin and North Dakota. All of the electric plants are subject to mortgages, which collateralize the outstanding first mortgage bonds of Minnesota Power and SWL&P. Most of the generating plants and substations are located on real property owned by Minnesota Power or SWL&P, subject to the lien of a mortgage, whereas most of the transmission and distribution lines are located on real property owned by others with appropriate easement rights or necessary permits from governmental authorities. WPPI Energy owns 20 percent of Boswell Unit 4. WPPI Energy has the right to use our transmission line facilities to transport its share of Boswell generation. (See Note 3. Jointly-Owned Facilities and Assets.) Regulatory Matters We are subject to the jurisdiction of various regulatory authorities and other organizations. Regulatory matters and proceedings are detailed in Note 4. Regulatory Matters, with a summary included in the following paragraphs. Electric Rates. All rates and contract terms in our Regulated Operations are subject to approval by applicable regulatory authorities. Minnesota Power and SWL&P design their retail electric service rates based on cost of service studies under which allocations are made to the various classes of customers as approved by the MPUC or the PSCW. Nearly all retail sales include billing adjustment clauses, which may adjust electric service rates for changes in the cost of fuel and purchased energy, recovery of current and deferred conservation improvement program expenditures and recovery of certain transmission, renewable and environmental investments. Minnesota Public Utilities Commission. The MPUC has regulatory authority over Minnesota Power’s retail service area in Minnesota, retail rates, retail services, capital structure, issuance of securities and other matters. Minnesota Power’s current retail rates are based on a 2018 MPUC retail rate order that allows for a 9.25 percent return on common equity and a 53.81 percent equity ratio. The resolution of Minnesota Power’s 2020 general rate case did not change the allowed return on equity or equity ratio. (See 2020 Minnesota General Rate Case.) As authorized by the MPUC, Minnesota Power also recognizes revenue under cost recovery riders for transmission and renewable investments. 2020 Minnesota General Rate Case. In November 2019, Minnesota Power filed a retail rate increase request with the MPUC seeking an average increase of approximately 10.6 percent for retail customers. The rate filing sought a return on equity of 10.05 percent and a 53.81 percent equity ratio. On an annualized basis, the requested final rate increase would have generated approximately $66 million in additional revenue. In December 2019 orders, the MPUC accepted the filing as complete and authorized an annual interim rate increase of $36.1 million beginning January 1, 2020. ALLETE, Inc. 2021 Form 10-K 15 REGULATED OPERATIONS (Continued) Regulatory Matters (Continued) In April 2020, Minnesota Power filed a request with the MPUC that proposed a resolution of Minnesota Power’s 2020 general rate case. Key components of our proposal included removing the power marketing margin credit in base rates and reflecting actual power marketing margins in the fuel adjustment clause effective May 1, 2020; refunding to customers interim rates collected through April 2020; increasing customer rates 4.1 percent compared to the 5.8 percent increase reflected in interim rates; and a provision that Minnesota Power would not file another rate case until at least November 1, 2021, unless certain events occur. In a June 2020 order, the MPUC approved Minnesota Power’s petition and proposal to resolve and withdraw the general rate case. Effective May 1, 2020, customer rates were set at an increase of 4.1 percent with the removal of the power marketing margin credit from base rates. Actual power marketing margins will be reflected in the fuel adjustment clause. Reserves for interim rates of $11.7 million were recorded in the second quarter of 2020 and refunded in the third and fourth quarters of 2020. 2022 Minnesota General Rate Case. On November 1, 2021, Minnesota Power filed a retail rate increase request with the MPUC seeking an average increase of approximately 18 percent for retail customers. The rate filing seeks a return on equity of 10.25 percent and a 53.81 percent equity ratio. On an annualized basis, the requested final rate increase would generate approximately $108 million in additional revenue. In orders dated December 30, 2021, the MPUC accepted the filing as complete and authorized an annual interim rate increase beginning January 1, 2022, with approximately $80 million expected to be collected in cash and approximately $8 million of interim rates for residential customers deferred with a final determination on recovery at the end of the rate case. Minnesota Power Land Sales. In August 2020, Minnesota Power filed a petition with the MPUC for approval to sell land that surrounds several reservoirs on its hydroelectric system and is no longer required to maintain its operations. The land has an estimated value of approximately $100 million, and Minnesota Power proposed to credit ratepayers the net proceeds from the sales in a future rate case or through its renewable resources rider to mitigate future rate increases. In an order dated November 18, 2021, the MPUC authorized the land sales and directed the net proceeds to be refunded to ratepayers subject to certain conditions and required compliance filings. 2021 Integrated Resource Plan. On February 1, 2021, Minnesota Power filed its latest IRP with the MPUC, which outlines its clean-energy transition plans through 2035. These plans include expanding its renewable energy supply to 70 percent by 2030, achieving coal-free operations at its facilities by 2035, and investing in a resilient and flexible transmission and distribution grid. Minnesota Power has also set a target to achieve an 80 percent reduction in carbon emissions by 2035 compared to 2005 levels. As part of these plans, Minnesota Power anticipates adding approximately 400 MW of new wind and solar energy resources, retiring Boswell Unit 3 by 2030 and transforming Boswell Unit 4 to be coal-free by 2035. Minnesota Power’s plans recognize that advances in technology will play a significant role in completing its transition to carbon-free energy supply, reliably and affordably. A final decision on the IRP is expected in the second half of 2022. Minnesota Power has a vision to deliver 100 percent carbon-free energy to customers by 2050, continuing its commitment to climate, customers and communities through its EnergyForward strategy. This vision builds on Minnesota Power’s recent achievement of now providing 50 percent renewable energy to its customers. Public Service Commission of Wisconsin. The PSCW has regulatory authority over SWL&P’s retail sales of electricity, natural gas and water, issuances of securities and other matters. SWL&P’s current retail rates are based on a December 2018 order that allows for a return on equity of 10.4 percent and a 55.0 percent equity ratio. The PSCW had directed SWL&P to file its next general rate case in 2020; however, the PSCW granted an extension request made by SWL&P to delay filing its next general rate case until on or before December 20, 2022. SWL&P requested the extension primarily due to impacts of the COVID-19 pandemic. North Dakota Public Service Commission. The NDPSC has jurisdiction over site and route permitting of generation and transmission facilities in North Dakota. Federal Energy Regulatory Commission. The FERC has jurisdiction over the licensing of hydroelectric projects, the establishment of rates and charges for transmission of electricity in interstate commerce, electricity sold at wholesale (including the rates for Minnesota Power’s municipal and wholesale customers), natural gas transportation, certain accounting and record‑keeping practices, certain activities of our regulated utilities and the operations of ATC. FERC jurisdiction also includes enforcement of NERC mandatory electric reliability standards. Violations of FERC rules are subject to enforcement action by the FERC including financial penalties up to $1 million per day per violation. ALLETE, Inc. 2021 Form 10-K 16 REGULATED OPERATIONS (Continued) Regional Organizations Midcontinent Independent System Operator, Inc. Minnesota Power, SWL&P and ATC are members of MISO, a regional transmission organization. While Minnesota Power and SWL&P retain ownership of their respective transmission assets, their transmission networks are under the regional operational control of MISO. Minnesota Power and SWL&P take and provide transmission service under the MISO open access transmission tariff. In cooperation with stakeholders, MISO manages the delivery of electric power across 15 states and the Canadian province of Manitoba. North American Electric Reliability Corporation. The NERC has been certified by the FERC as the national electric reliability organization. The NERC ensures the reliability of the North American bulk power system. The NERC oversees six regional entities that establish requirements, approved by the FERC, for reliable operation and maintenance of power generation facilities and transmission systems. Minnesota Power is subject to these reliability requirements and can incur significant penalties for non‑compliance. Midwest Reliability Organization (MRO). Minnesota Power and ATC are members of the MRO, one of the six regional entities overseen by the NERC. The MRO's primary responsibilities are to: ensure compliance with mandatory reliability standards by entities who own, operate or use the interconnected, international bulk power system; conduct assessments of the grid's ability to meet electricity demand in the region; and analyze regional system events. The MRO region spans the Canadian provinces of Saskatchewan and Manitoba, and all or parts of 16 states. Minnesota Legislation Renewable Energy. Minnesota law requires 25 percent of electric utilities’ applicable retail and municipal energy sales in Minnesota to be from renewable energy sources by 2025. Minnesota law also requires Minnesota Power to meet interim milestones including 20 percent by 2020. The law allows the MPUC to modify or delay meeting a milestone if implementation will cause significant ratepayer cost or technical reliability issues. If a utility is not in compliance with a milestone, the MPUC may order the utility to construct facilities, purchase renewable energy or purchase renewable energy credits. Minnesota Power has exceeded the interim milestone requirements to date. As of December 31, 2021, approximately 50 percent of Minnesota Power’s power supply was provided by renewable energy sources. (See Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Outlook – EnergyForward.) Minnesota Solar Energy Standard. Minnesota law requires at least 1.5 percent of total retail electric sales, excluding sales to certain customers, to be generated by solar energy. At least 10 percent of the 1.5 percent mandate must be met by solar energy generated by or procured from solar photovoltaic devices with a nameplate capacity of 40 kW or less and community solar garden subscriptions. Minnesota Power has met both parts of the solar mandate to date. Competition Retail electric energy sales in Minnesota and Wisconsin are made to customers in assigned service territories. As a result, most retail electric customers in Minnesota do not have the ability to choose their electric supplier. Large energy users of 2 MW and above that are located outside of a municipality are allowed to choose a supplier upon MPUC approval. Minnesota Power served 8 Large Power Customers under contracts of at least 10 MW in 2021, none of which have engaged in a competitive rate process. (See Electric Sales / Customers.) No other large commercial or small industrial customers in Minnesota Power’s service territory have sought a provider outside Minnesota Power’s service territory. Retail electric and natural gas customers in Wisconsin do not have the ability to choose their energy supplier. In both states, however, electricity may compete with other forms of energy. Customers may also choose to generate their own electricity, or substitute other forms of energy for their manufacturing processes. In 2021, 4 percent of total regulated utility kWh sales were to municipal customers in Minnesota. These customers have the right to seek an energy supply from any wholesale electric service provider upon contract expiration. Minnesota Power’s wholesale electric contract with the Nashwauk Public Utilities Commission was extended in 2020 and is effective through December 31, 2037. Minnesota Power’s wholesale electric contracts with 14 non-affiliated municipal customers are effective through varying dates ranging from 2024 through 2029. (See Electric Sales / Customers.) ALLETE, Inc. 2021 Form 10-K 17 REGULATED OPERATIONS (Continued) Competition (Continued) The FERC has continued with its efforts to promote a competitive wholesale market through open-access electric transmission and other means. As a result, our electric sales to Other Power Suppliers and our purchases to supply our retail and wholesale load are made in a competitive market. Franchises Minnesota Power holds franchises to construct and maintain an electric distribution and transmission system in 95 cities. The remaining cities, villages and towns served by Minnesota Power do not require a franchise to operate. SWL&P serves customers under electric, natural gas or water franchises in 1 city and 14 villages and towns. ALLETE CLEAN ENERGY ALLETE Clean Energy focuses on developing, acquiring, and operating clean and renewable energy projects. ALLETE Clean Energy currently owns and operates, in seven states, more than 1,300 MW of nameplate capacity wind energy generation that is contracted under PSAs of various durations. In addition, ALLETE Clean Energy currently has approximately 200 MW of wind energy facilities under contract to be sold to others. ALLETE Clean Energy also engages in the development of wind energy facilities to operate under long-term PSAs or for sale to others upon completion. (See Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Outlook – ALLETE Clean Energy.) ALLETE Clean Energy believes the market for renewable energy in North America is robust, driven by several factors including environmental regulation, tax incentives such as the extension of production tax credit and investment tax credits, societal expectations and continual technology advances. State renewable portfolio standards, state or federal regulations to limit GHG emissions and the extension of production tax credit and investment tax credits are examples of environmental regulation or public policy that we believe will drive renewable energy development. ALLETE Clean Energy’s strategy includes the safe, reliable, optimal and profitable operation of its existing facilities. This includes a strong safety culture, the continuous pursuit of operational efficiencies at existing facilities and cost controls. ALLETE Clean Energy generally acquires facilities in liquid power markets and its strategy includes the exploration of PSA extensions upon expiration of existing contracts, production tax credit requalification of existing facilities or the sale of facilities. ALLETE, Inc. 2021 Form 10-K 18 ALLETE CLEAN ENERGY (Continued) ALLETE Clean Energy manages risk by having a diverse portfolio of assets, which includes PSA expiration, technology and geographic diversity. The current operating portfolio is subject to typical variations in seasonal wind with higher wind resources typically available in the winter months. The majority of its planned maintenance leverages this seasonality and is performed during lower wind periods. ALLETE Clean Energy’s current operating portfolio is as follows: Region East Midwest South West Wind Energy Facility Armenia Mountain Chanarambie/Viking PSA 1 (a) PSA 2 Lake Benton Storm Lake I Storm Lake II PSA 1 PSA 2 Other Caddo PSA 1 PSA 2 PSA 3 Diamond Spring PSA 1 PSA 2 PSA 3 Condon Glen Ullin South Peak Capacity MW 101 98 PSA MW 100% PSA Expiration 2024 104 108 77 17 303 303 50 106 80 12% 88% 100% 100% 90% 10% 100% 26% 66% 7% 58% 25% 16% 100% 100% 100% 2023 2023 2028 2027 2022 2032 2028 2034 2034 2034 2035 2032 2035 2022 2039 2035 (a) The PSA expiration assumes the exercise of four one-year renewal options that ALLETE Clean Energy has the sole right to exercise. The majority of ALLETE Clean Energy’s wind operations are located on real property owned by others with easement rights or necessary consents of governmental authorities. One of ALLETE Clean Energy’s wind energy facilities is encumbered by liens against its assets securing financing. ALLETE Clean Energy’s Glen Ullin, South Peak, Diamond Spring and Caddo wind energy facilities are subject to tax equity financing structures. (See Note 1. Operations and Significant Accounting Policies.) U.S. WATER SERVICES U.S. Water Services provided integrated water management for industry by combining chemical, equipment, engineering and service for customized solutions to reduce water and energy usage, and improve efficiency. In March 2019, the Company sold U.S. Water Services to a subsidiary of Kurita Water Industries Ltd. pursuant to a stock purchase agreement for approximately $270 million in cash, net of transaction costs and cash retained. The Company recognized a gain on the sale of U.S. Water Services of $13.2 million after-tax in 2019. ALLETE used the proceeds from the sale of U.S. Water Services to reinvest in growth initiatives at our Regulated Operations and ALLETE Clean Energy. CORPORATE AND OTHER BNI Energy BNI Energy is a supplier of lignite coal in North Dakota, producing approximately 4 million tons annually and has an estimated 650 million tons of lignite coal reserves. Two electric generating cooperatives, Minnkota Power and Square Butte, consume virtually all of BNI Energy’s production of lignite under cost-plus fixed fee coal supply agreements extending through December 31, 2037. (See Item 1. Business – Regulated Operations – Power Supply – Long- Term Purchased Power and Note 8. Commitments, Guarantees and Contingencies.) The mining process disturbs and reclaims between 200 and 250 acres per year. Laws require that the reclaimed land be at least as productive as it was prior to mining. As of December 31, 2021, BNI Energy’s total reclamation liability is estimated at $70.7 million and is included in Other Non-Current Liabilities on the Consolidated Balance Sheet. These costs are included in the cost-plus fixed fee contract, for which an asset reclamation cost receivable was included in Other Non-Current Assets on the Consolidated Balance Sheet. The asset reclamation obligation is guaranteed by surety bonds and a letter of credit. (See Note 8. Commitments, Guarantees and Contingencies.) ALLETE, Inc. 2021 Form 10-K 19 CORPORATE AND OTHER (Continued) Investment in Nobles 2 Our subsidiary, ALLETE South Wind, owns a 49 percent equity interest in Nobles 2, the entity that owns and operates a 250 MW wind energy facility in southwestern Minnesota pursuant to a 20-year PPA with Minnesota Power. As of December 31, 2021, our equity investment in Nobles 2 was $163.5 million ($152.2 million at December 31, 2020). (See Note 5. Equity Investments.) South Shore Energy South Shore Energy, ALLETE’s non-rate regulated, Wisconsin subsidiary, is developing NTEC, an approximately 600 MW proposed combined-cycle natural gas-fired generating facility to be built in Superior, Wisconsin, which will be jointly owned by Dairyland Power Cooperative, Basin and South Shore Energy. Minnesota Power is expected to purchase approximately 20 percent of the facility's output starting in 2025 pursuant to a capacity dedication agreement. Construction of NTEC is subject to obtaining additional permits from local, state and federal authorities. The total project cost is estimated to be approximately $700 million, of which South Shore Energy’s portion is expected to be approximately $150 million. South Shore Energy’s portion of NTEC project costs incurred through December 31, 2021, is approximately $5 million. On October 1, 2021, South Shore Energy sold a portion of its undivided ownership interest in NTEC for approximately $20 million representing reimbursement of current costs plus a fee for prior development costs and risks incurred. Following the transaction, South Shore Energy now owns a 20 percent undivided ownership interest in NTEC, Basin owns a 30 percent undivided ownership interest in NTEC and Dairyland Power Cooperative continues to own a 50 percent undivided ownership interest in NTEC. The closing of the transaction resulted in the recognition of an approximately $8.5 million after-tax gain recorded in Corporate and Other in the fourth quarter of 2021, related to prior development costs and risks incurred. ALLETE Properties ALLETE Properties represents our legacy Florida real estate investment. ALLETE Properties’ major project in Florida is Town Center at Palm Coast, which consists of approximately 500 acres of land as well as various residential units and non-residential square footage. In addition to the Town Center at Palm Coast project, ALLETE Properties has approximately 500 acres of other land available for sale. (See Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Outlook – Corporate and Other – ALLETE Properties.) Seller Financing. ALLETE Properties occasionally provides seller financing to qualified buyers. As of December 31, 2021, outstanding finance receivables were $7.6 million, net of reserves, with maturities through 2026. These finance receivables accrue interest at market-based rates and are collateralized by the financed properties. Regulation. A substantial portion of our development properties in Florida are subject to federal, state and local regulations, and restrictions that may impose significant costs or limitations on our ability to develop the properties. Much of our property is vacant land and some is located in areas where development may affect the natural habitats of various protected wildlife species or in sensitive environmental areas such as wetlands. Non-Rate Base Generation and Miscellaneous Corporate and Other also includes other business development and corporate expenditures, unallocated interest expense, a small amount of non-rate base generation, approximately 4,000 acres of land in Minnesota, and earnings on cash and investments. As of December 31, 2021, non-rate base generation consists of 29 MW of natural gas and hydro generation at Rapids Energy Center in Grand Rapids, Minnesota, which is primarily dedicated to the needs of one customer, UPM Blandin. ALLETE, Inc. 2021 Form 10-K 20 ENVIRONMENTAL MATTERS Our businesses are subject to regulation of environmental matters by various federal, state and local authorities. A number of regulatory changes to the Clean Air Act, the Clean Water Act and various waste management requirements have been promulgated by both the EPA and state authorities over the past several years. Minnesota Power’s facilities are subject to additional requirements under many of these regulations. Minnesota Power is reshaping its generation portfolio, over time, to reduce its reliance on coal, has installed cost-effective emission control technology, and advocates for sound science and policy during rulemaking implementation. We consider our businesses to be in substantial compliance with currently applicable environmental regulations and believe all necessary permits have been obtained. We anticipate that with many state and federal environmental regulations and requirements finalized, or to be finalized in the near future, potential expenditures for future environmental matters may be material and require significant capital investments. Minnesota Power has evaluated various environmental compliance scenarios using possible outcomes of environmental regulations to project power supply trends and impacts on customers. We review environmental matters on a quarterly basis. Accruals for environmental matters are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated based on current law and existing technologies. Accruals are adjusted as assessment and remediation efforts progress, or as additional technical or legal information becomes available. Accruals for environmental liabilities are included in the Consolidated Balance Sheet at undiscounted amounts and exclude claims for recoveries from insurance or other third parties. Costs related to environmental contamination treatment and cleanup are expensed unless recoverable in rates from customers. (See Note 8. Commitments, Guarantees and Contingencies.) HUMAN CAPITAL MANAGEMENT The Company’s key human capital management objectives are to attract, recognize and retain high quality talent, align with strategic business objectives and support the Company’s values. To support these objectives, the Company’s programs are designed to develop talent; reward and support employees through competitive compensation programs and benefit plans; enhance the Company’s culture through efforts aimed at making the workplace more engaging, safe and inclusive; and acquire talent and leverage internal opportunities to create a high-performing, diverse workforce. Our management and Board of Directors play key roles in reviewing and overseeing our human capital practices. As of December 31, 2021, ALLETE had 1,365 employees, of which 1,340 were full-time. Minnesota Power and SWL&P have an aggregate of 469 employees covered under collective bargaining agreements, of which most are members of the International Brotherhood of Electrical Workers (IBEW) Local 31. The current labor agreements with IBEW Local 31 expire on April 30, 2023 for Minnesota Power and January 31, 2024 for SWL&P. BNI Energy has 127 employees that are members of IBEW Local 1593. The current labor agreement with IBEW Local 1593 expires on March 31, 2023. Integrity. Integrity is a foundational, shared value at ALLETE, is important to ALLETE’s business and operations, and enables our success. The Company has a written Code of Ethics that applies to all of our employees. Health and Safety. The success of our business is fundamentally connected to the well-being of our people. We continue to respond to the COVID-19 pandemic by taking steps to mitigate the potential risks to us posed by its transmission and have implemented company-wide business continuity plans in response to the pandemic. These plans guide our response, business continuity, and the precautionary measures we are taking on behalf of employees and the public. ALLETE, Inc. 2021 Form 10-K 21 HUMAN CAPITAL MANAGEMENT (Continued) Zero Injury Culture. Our journey to Zero Injury starts with a culture that is open and transparent. We encourage all employees to report injuries, near misses, and good catches, so that we can learn and share with others throughout the Company in an effort to improve safety performance. Leaders have regular safety conversations with employees, where the data learned from the conversations is examined, shared with the ALLETE safety strategy team and used to improve the Company’s safety programs. To monitor progress, the Company uses leading and lagging indicators to analyze injury trends, safety participation and other data to make better decision on safety practices. Talent Attraction, Retention and Development. For more than a century, ALLETE has been successful because of our ability to attract and retain high- quality people who demonstrate our shared values. We engage in workforce planning, and succession planning, while building a robust talent pipeline and monitoring turnover. We recognize and support the growth and development of our employees and offer opportunities to participate in internal and external learning programs. Our internal talent development programs provide employees with the resources they need to develop proficiency in their role, help achieve their career goals and build leadership skills. We are focusing initiatives on programs to expand the diversity of new hires and updating on-the-job trainings—including apprenticeships and scholarships aimed at bridging opportunity gaps—as we recognize the importance of a strong talent pipeline. In addition to role specific training, targeted training also includes respect in the workplace, cyber awareness, safety, integrity and leadership development. Compensation and Benefits. Our competitive compensation package gives employees flexibility, choices and opportunities. Competitive compensation is important for the Company to attract and retain a qualified workforce to successfully manage our business and achieve our business objectives. We also strive to ensure pay equity amongst diverse employees performing equal or substantially similar work. Periodically, we review the median pay of our male and female employees as well as employees from diverse backgrounds. Diversity, Equity and Inclusion. Increasing staff diversity enriches our workforce culture at ALLETE. Our employees are operating in an increasingly diverse society. In order to be accountable to our employees and stakeholders, we strive to have a workforce that reflects the diversity of the communities we serve, promotes inclusivity and is equitable. At ALLETE, we want to ensure that we have a workplace culture where we treat each other with fairness, dignity and respect. The Company has a respect in the workplace initiative, which includes education as well as ongoing discussions focused on building respectful relationships and managing bias. We continue our efforts in crafting a framework to strengthen ALLETE’s diversity, equity and inclusion efforts in the areas of: workforce, supply chain and ALLETE as a community citizen. In 2021, ALLETE took tangible steps toward advancing diversity, equity and inclusion by continuing to raise awareness, furthering intentional external relationships/partnerships, increasing supplier diversity, focus on underrepresented groups through grants/scholarships and other Company and employee giving. Yellow Ribbon Program. ALLETE and its subsidiaries are dedicated to supporting veterans, military members and their families. An employee effort grew out of that spirit of commitment to veterans and led the state of Minnesota to designate ALLETE/Minnesota Power and ALLETE Clean Energy as Yellow Ribbon Companies. The mission of ALLETE’s Yellow Ribbon Program is to contribute to the Company’s unique culture by proactively recruiting and retaining the best and supporting an environment in which military-connected employees can thrive.

Risk Factors The risks and uncertainties discussed below could materially affect our business operations, financial position, results of operations and cash flows, and should be carefully considered by stakeholders. The risks and uncertainties in this section are not the only ones we face; additional risks and uncertainties that we are not presently aware of, or that we currently consider immaterial, may also affect our business operations, financial position, results of operations and cash flows. Accordingly, the risks described below should be carefully considered together with other information set forth in this report and in future reports that we file with the SEC. Regulated Operations Risks Our results of operations could be negatively impacted if our taconite, paper and pipeline customers experience an economic downturn, incur work stoppages, fail to compete effectively, experience decreased demand, fail to economically obtain raw materials, fail to renew or obtain necessary permits, or experience a decline in prices for their product. Minnesota Power’s Large Power Customers (see Item 1. Business – Regulated Operations – Electric Sales / Customers) and Silver Bay Power accounted for 32 percent of our 2021 consolidated operating revenue (29 percent in 2020 and 30 percent in 2019) and 37 percent of Regulated Operations operating revenue (34 percent in 2020 and 36 percent in 2019). Minnesota Power’s taconite customers, which are currently owned by only two entities at the end of 2021, accounted for approximately 28 percent of consolidated operating revenue and 32 percent of Regulated Operations operating revenue in 2021. These customers are involved in cyclical industries that by their nature are adversely impacted by economic downturns and are subject to strong competition in the marketplace. The North American paper and pulp industry also faces declining demand due to the impact of electronic substitution for print and changing customer needs. As a result, certain paper and pulp customers have reduced their existing operations or idled facilities in recent years and have pursued or are pursuing product changes in response to declining demand. Additionally, the taconite industry could be impacted by changing technology in the steel industry such as the adoption of electric arc furnaces for steelmaking, which could result in declining demand for taconite and the electricity used during its production. Minnesota Power also serves two pipeline customers that accounted for 2 percent of our 2021 consolidated operating revenue (2 percent in 2020 and in 2019) and 2 percent of Regulated Operations revenue in 2021 (3 percent in 2020 and 3 percent in 2019). These customers are involved in an industry that is seeing increased environmental pressure for construction of new or expanded pipeline infrastructure for the transportation of fossil fuels. Changes in regulatory rulings or permit proceedings could result in changes to operations of the pipeline network in our service territory. Accordingly, if our industrial customers experience an economic downturn, incur a work stoppage (including strikes, lock-outs or other events), fail to compete effectively, experience decreased demand, fail to economically obtain raw materials, fail to renew or obtain necessary permits, or experience a decline in prices for their product, there could be adverse effects on their operations and, consequently, this could have a negative impact on our results of operations as we are unable to remarket at similar prices the energy that would otherwise have been sold to such customers. These customers have also been impacted by the ongoing COVID-19 pandemic. (See Entity-wide Risks.) We may not be able to successfully implement our strategic objectives of growing load at our utilities if current or potential industrial or municipal customers are unable to successfully implement expansion plans, including the inability to obtain necessary governmental permits and approvals. As part of our long-term strategy, we pursue new wholesale and retail loads in and around our service territories. Currently, there are several companies in northeastern Minnesota that are in the process of developing natural resource-based projects that represent long-term growth potential and load diversity for our Regulated Operations businesses. These projects may include construction of new facilities and restarts of old facilities, both of which require permitting and approvals to be obtained before the projects can be successfully implemented. If a project does not obtain any necessary governmental (including environmental) permits and approvals or if these customers are unable to successfully implement expansion plans, our long-term strategy and thus our results of operations could be adversely impacted. ALLETE, Inc. 2021 Form 10-K 24 Item 1A. Risk Factors (Continued) Regulated Operations Risks (Continued) Our businesses, investments and customers are subject to an extensive legal and regulatory framework under federal and state laws as well as regulations imposed by other organizations that may have a negative impact on our business and results of operations. Our businesses, investments and customers are subject to an extensive legal and regulatory framework imposed under federal and state law including regulations administered by the FERC, MPUC, MPCA, PSCW, NDPSC and EPA as well as regulations administered by other organizations including the NERC. These laws and regulations relate to allowed rates of return, capital structure, financings, rate and cost structure, acquisition and disposal of assets and facilities, construction and operation of generation, transmission and distribution facilities (including the ongoing maintenance and reliable operation of such facilities), recovery of purchased power costs and capital investments, approval of integrated resource plans and present or prospective wholesale and retail competition, renewable portfolio standards that require utilities to obtain specified percentages of electric supply from eligible renewable generation sources, among other things. Energy policy initiatives at the state or federal level could increase renewable portfolio standards or incentives for distributed generation, municipal utility ownership, or local initiatives could introduce generation or distribution requirements that could change the current integrated utility model. Our transmission systems and electric generation facilities are subject to the NERC mandatory reliability standards, including cybersecurity standards. Compliance with these standards may lead to increased operating costs and capital expenditures which are subject to regulatory approval for recovery. If it was determined that we were not in compliance with these mandatory reliability standards or other statutes, rules and orders, we could incur substantial monetary penalties and other sanctions, which could adversely affect our results of operations. These laws and regulations significantly influence our operations and may affect our ability to recover costs from our customers. We are required to have numerous permits, licenses, approvals and certificates from the agencies and other organizations that regulate our business. We believe we have obtained the necessary permits, licenses, approvals and certificates for our existing operations and that our business is conducted in accordance with applicable laws; however, we are unable to predict the impact on our operating results from the future regulatory activities of any of these agencies and other organizations. Changes in regulations, timing of approvals, the adoption of new regulations or the expansion of jurisdiction by these agencies and other organizations could have an adverse impact on our business and results of operations. Our ability to obtain rate adjustments to maintain reasonable rates of return depends upon regulatory action under applicable statutes and regulations, and we cannot provide assurance that rate adjustments will be obtained or reasonable authorized rates of return on capital will be earned. Minnesota Power and SWL&P, from time to time, file general rate cases with, or otherwise seek cost recovery authorization from, federal and state regulatory authorities. If Minnesota Power and SWL&P do not receive an adequate amount of rate relief in general rate cases, including if rates are reduced, if increased rates are not approved or recovered on a timely basis, if fuel adjustment clause recoveries or cost recovery for other items are not granted at the requested level, or costs are otherwise unable to be recovered through rates, we may experience an adverse impact on our financial position, results of operations and cash flows. We are unable to predict the impact on our business and results of operations from future legislation or regulatory activities of any of these agencies or organizations. Our regulated operations present certain environmental risks that could adversely affect our financial position and results of operations, including effects of environmental laws and regulations, physical risks associated with climate change and initiatives designed to reduce the impact of GHG emissions. We are subject to extensive environmental laws and regulations affecting many aspects of our past, present and future operations, including air quality, water quality and usage, waste management, reclamation, hazardous wastes, avian mortality and natural resources. These laws and regulations, or new laws and regulations that may be passed, can result in increased capital expenditures and increased operating and other costs as a result of compliance, remediation, containment and monitoring obligations, particularly with regard to laws relating to emissions, coal ash and water discharge at generating facilities. These laws and regulations could restrict the output of some existing facilities, limit the use of some fuels in the production of electricity, require the installation of additional pollution control equipment, require participation in environmental emission allowance trading, and lead to other environmental considerations and costs, which could have an adverse impact on our business, operations and results of operations. ALLETE, Inc. 2021 Form 10-K 25 Item 1A. Risk Factors (Continued) Regulated Operations Risks (Continued) These laws and regulations generally require us to obtain and comply with a wide variety of environmental licenses, permits, inspections and other approvals. Violations of these laws and regulations could expose us to regulatory and legal proceedings, disputes with, and legal challenges by, governmental authorities and private parties, as well as potential significant civil fines criminal penalties and other sanctions. Existing environmental regulations may be revised and new environmental regulations may be adopted or become applicable to us. Revised or additional regulations which result in increased compliance costs or additional operating restrictions, particularly if those costs are not fully recoverable from customers, could have an adverse effect on our results of operations. There is significant uncertainty regarding if and when new laws, regulations or administrative policies will be adopted to reduce or limit GHG and the impact any such laws or regulations would have on us. In 2021, our operating coal-fired generating facilities consisted of the 355 MW Boswell Unit 3 and the 468 MW Boswell Unit 4. (See Outlook – EnergyForward.) Any future limits on GHG emissions at the federal or state level, or action taken by regulators, before these facilities are retired or become coal-free may require us to incur significant capital expenditures and increases in operating costs, or could result in early closure of coal-fired generating facilities, stranded assets, an impairment of assets, denial of full recovery of decommissioning costs in excess of amounts previously collected, or otherwise adversely affect our results of operations, particularly if resulting expenditures and costs are not fully recoverable from customers. Our regulated operations may be adversely impacted by the physical and financial risks associated with climate change. See Entity-wide Risks for additional discussion of risks related to GHG and climate change. We cannot predict the amount or timing of all future expenditures related to environmental matters because of uncertainty as to applicable regulations or requirements. There is also uncertainty in quantifying liabilities under environmental laws that impose joint and several liability on all potentially responsible parties. Violations of certain environmental statutes, rules and regulations could expose ALLETE to third party disputes and potentially significant monetary penalties, as well as other sanctions for non‑compliance. The operation and maintenance of our regulated electric generation and transmission facilities are subject to operational risks that could adversely affect our financial position, results of operations and cash flows. The operation of generating facilities involves many risks, including start-up operational risks, breakdown or failure of facilities, the dependence on a specific fuel source, inadequate fuel supply, availability of fuel transportation, and the impact of unusual or adverse weather conditions or other natural events, as well as the risk of performance below expected levels of output or efficiency. A significant portion of our facilities contain older generating equipment, which, even if maintained in accordance with good engineering practices, may require significant capital expenditures to continue operating at peak efficiency. Generation and transmission facilities and equipment are also likely to require periodic upgrades and improvements due to changing environmental standards and technological advances. We could be subject to costs associated with any unexpected failure to produce or deliver power, including failure caused by breakdown, forced outage or limited availability of fuel or fuel transportation, as well as the repair of damage to facilities due to breakdown, storms, natural disasters, wars, sabotage, terrorist acts and other catastrophic events. This could also lead to requiring additional purchased power to meet requirements of serving our retail load, which for Minnesota Power is subject to recovery under the fuel adjustment clause. Should these costs be denied or are otherwise unable to be recovered, our financial position, results of operations and cash flows could be adversely impacted. Our ability to successfully and timely complete capital repairs or improvements to existing regulated facilities or other capital projects is contingent upon many variables. We expect to incur significant capital expenditures in making capital repairs or improvements to our existing electric generation and transmission facilities and in the development and construction of new electric generation and transmission facilities. Should any such efforts be unsuccessful, not completed in a timely manner or if there are increases in the costs for or limited availability of key materials, supplies, labor and services, we could be subject to additional costs or impairments which could have an adverse impact on our financial position, results of operation and cash flows. ALLETE, Inc. 2021 Form 10-K 26 Item 1A. Risk Factors (Continued) Regulated Operations Risks (Continued) Our regulated electric generating operations may not have access to adequate and reliable transmission and distribution facilities necessary to deliver electricity to our customers. We depend on our own transmission and distribution facilities, as well as facilities owned by other utilities, to deliver the electricity produced and sold to our customers, and to other energy suppliers. If transmission capacity is inadequate, our ability to sell and deliver electricity may be limited. We may have to forgo sales or may have to buy more expensive wholesale electricity that is available in the capacity-constrained area. In addition, any infrastructure failure that interrupts or impairs delivery of electricity to our customers could negatively impact the satisfaction of our customers, which could have an adverse impact on our business and results of operations. The price of electricity may be volatile and fuel may be volatile and availability may be limited. Volatility in market prices for electricity and volatility and limited availability of fuel could adversely impact our financial position and results of operations and may result from: severe or unexpected weather conditions and natural disasters; seasonality; changes in electricity usage; transmission or transportation constraints, inoperability or inefficiencies; availability of competitively priced alternative energy sources; changes in supply and demand for energy; changes in power production capacity; outages at our generating facilities or those of our competitors; availability of fuel and transportation of fuel; changes in production and storage levels of natural gas, lignite, coal, crude oil and refined products; • • • • • • • • • • • wars, sabotage, terrorist acts or other catastrophic events; and • federal, state, local and foreign energy, environmental, or other regulation and legislation. Volatility in market prices for our fuel and purchase power costs impacts our sales to retail, municipal and Other Power Suppliers. Fluctuations in our fuel and purchased power costs related to our retail and municipal customers are passed on to customers through the fuel adjustment clause; however, our results of operations and cash flows may be adversely impacted if increased fuel adjustment clause rates are not approved or recovered on a timely basis, if cost recovery is not granted at the requested level, or costs are otherwise unable to be recovered through the fuel adjustment clause. Wholesale prices for electricity have also declined in recent years primarily due to low natural gas prices, the extension of renewable tax credits and additional renewable generation commencing operations. If there are reductions in demand from current customers, we lose retail customers, or we lose municipal customers that do not renew existing contracts, we will market any available power to Other Power Suppliers in an effort to mitigate any earnings impact. Sales to Other Power Suppliers are sold at market-based prices into the MISO market on a daily basis or through bilateral agreements of various durations. Due to wholesale prices for electricity being below our rates for retail and municipal customers, we do not expect that our power marketing efforts would fully offset the reduction in earnings resulting from the lower demand from existing customers or the loss of customers. (See Item 1. Business – Regulated Operations – Electric Sales / Customers.) ALLETE, Inc. 2021 Form 10-K 27 Item 1A. Risk Factors (Continued) Regulated Operations Risks (Continued) Demand for energy may decrease. Our results of operations are impacted by the demand for energy in our service territories, our municipal customers and other power suppliers. There could be lower demand for energy due to a loss of customers as a result of economic conditions, customers constructing or installing their own generation facilities, higher costs and rates charged to customers, eligible municipal and other power suppliers choosing an alternative energy provider, or loss of service territory or franchises. Further, energy conservation and technological advances that increased energy efficiency may temporarily or permanently reduce the demand for energy products. In addition, we are impacted by state and federal regulations requiring mandatory conservation measures, which reduce the demand for energy products. Continuing technology improvements and regulatory developments may make customer and third party-owned generation technologies such as rooftop solar systems, WTGs, microturbines and battery storage systems more cost effective and feasible for of our customers. If customers utilize their own generation, demand for energy from us would decline. There may not be future economic growth opportunities that would enable us to replace the lost energy demand from these customers. Therefore, a decrease in demand for energy could adversely impact our financial position, results of operations and cash flows. ALLETE Clean Energy / Corporate and Other Risks The inability to successfully manage and grow ALLETE Clean Energy and our Corporate and Other businesses could adversely affect our results of operations. The Company's strategy includes adding customers, new geographies, and growth through acquisitions or project development with long-term PSAs in place for the output or to be sold upon completion. This strategy depends, in part, on the Company’s ability to successfully identify and evaluate acquisition or development opportunities and consummate acquisitions on acceptable terms. The Company may compete with other companies for these acquisition and development opportunities, which may increase the Company’s cost of making acquisitions and the Company may be unsuccessful in pursuing these acquisition opportunities. Other companies may be able to pay more for acquisitions and may be able to identify, evaluate, bid for and purchase a greater number of assets than the Company’s financial or human resources permit. New laws and regulations promoting renewable energy generation may result in increased competition. Our ALLETE Clean Energy business is experiencing return pressures from increased competition, and lower forward price curves, as a growing amount of investment capital is being directed into wind generation opportunities. In addition, current and potential new project developments can be negatively affected by a lower ALLETE stock price, which may result in such projects not being accretive, or otherwise unable to satisfy our financial objectives criteria to proceed. Additionally, tax law changes may adversely impact the economic characteristics of potential acquisitions or investments. Any reductions or modifications to, or the elimination of, governmental incentives or policies that support renewable energy or the imposition of additional taxes or other assessments on renewable energy, could result in, among other items, the lack of a satisfactory market for the development or financing of new renewable energy projects and reduced project returns on future projects. If the Company is unable to execute its strategy of growth through acquisitions, project development for others, or the addition of new customers and geographies, it may impede our long-term objectives and business strategy. Acquisitions are subject to uncertainties. If we are unable to successfully integrate and manage future acquisitions or strategic investments, this could have an adverse impact on our results of operations. Our actual results may also differ from our expectations due to factors such as the ability to obtain timely regulatory or governmental approvals, integration and operational issues and the ability to retain management and other key personnel. ALLETE, Inc. 2021 Form 10-K 28 Item 1A. Risk Factors (Continued) ALLETE Clean Energy / Corporate and Other Risks (Continued) The generation of electricity from wind and solar energy facilities depends heavily on suitable meteorological conditions. Although our electric generation facilities are located in diverse geographic regions to reduce the potential impact that may be caused by unfavorable weather in a particular region, suitable meteorological conditions are variable and difficult to predict. If wind or solar conditions are unfavorable or meteorological conditions are unsuitable, electricity generation and revenue from wind and solar energy facilities may be substantially below our expectations. The electricity produced, production tax credits received, and revenues generated by a wind or solar energy facility are highly dependent on suitable wind conditions and associated weather conditions, which are variable and beyond our control. We base our decisions about which wind and solar projects to build or acquire as well as our electricity generation estimates, in part, on the findings of long-term wind and other meteorological studies conducted on the project site and its region; however, the unpredictable nature of wind and solar conditions, weather and meteorological conditions can result in material deviations from these studies and our expectations. Furthermore, components of our systems could be damaged by severe weather, such as hailstorms, lightning or tornadoes. In addition, replacement and spare parts for key components may be difficult or costly to acquire or may be unavailable. Unfavorable wind and solar conditions, weather or changes to meteorological patterns could impair the effectiveness of our electric generation facility assets, reduce their output beneath their rated capacity or require shutdown of key equipment, impeding operation of our wind energy facilities or lead to an impairment of assets. The construction, operation and maintenance of our electric generation facilities or investment in facilities are subject to operational risks that could adversely affect our financial position, results of operations and cash flows. The construction and operation of generating facilities involves many risks, including the performance by key contracted suppliers and maintenance providers; increases in the costs for or limited availability of key materials, supplies, labor and services; start-up operations risks; breakdown or failure of facilities; curtailment of facilities by counterparties; the dependence on the availability of wind resources; or the impact of unusual, adverse weather conditions or other natural events, as well as the risk of performance below expected levels of output or efficiency. Some of our facilities contain older generating equipment, which even if maintained in accordance with good engineering practices, may require significant capital expenditures to continue operating at peak efficiency. We could be subject to costs associated with any unexpected failure to produce and deliver power, including failure caused by breakdown or forced outage, as well as the repair of damage to facilities due to storms, natural disasters, wars, sabotage, terrorist acts and other catastrophic events. The price of electricity may be volatile, which may impact results of operations at ALLETE Clean Energy wind energy facilities under contracts with customer and industrial (C&I) customers. Unusual, adverse weather conditions or other natural events can cause volatility in market prices for electricity and adversely affect our financial position, results of operations and cash flows. ALLETE Clean Energy’s power sales agreements with its three C&I customers at its Diamond Spring wind energy facility are contracts for differences where power is delivered to the market, and a fixed price is paid by the customers to ALLETE Clean Energy, and differences between the market price and the fixed price are paid to or received from the customers. One of these power sales agreements settles with the customer based on day-ahead electricity prices, while deliveries to the market are settled based on real-time electricity prices. This settlement provision can and has resulted in an adverse impact to the Company when market prices are extremely volatile as happened in February 2021 during an extreme winter weather event in the southwest United States. This winter weather event caused extreme volatility, with large differences in the day-ahead and real-time market prices; the settlement provision resulted in an approximately $5 million after-tax negative impact related to the Diamond Spring wind energy facility in 2021. As contracts with counterparties expire, we may not be able to replace them with agreements on similar terms or divest the related assets at a profit. ALLETE Clean Energy is party to PSAs which expire in various years between 2022 and 2039. These PSA expirations are prior to the end of the estimated useful lives of the respective wind energy facilities. If, for any reason, ALLETE Clean Energy is unable to enter into new agreements with existing or new counterparties on similar terms once the current agreements expire, sell energy in the wholesale market resulting in similar revenue, or enter into a contract to sell the facility at a profit, our financial position, results of operations and cash flows could be adversely affected, which includes potential impairment of property, plant and equipment. ALLETE, Inc. 2021 Form 10-K 29 Item 1A. Risk Factors (Continued) ALLETE Clean Energy / Corporate and Other Risks (Continued) Counterparties to turbine and other generation supply, service and maintenance, or power sale agreements may not fulfill their obligations. Our businesses are party to turbine and other generation supply agreements, service and maintenance agreements, and PSAs under various durations with a limited number of creditworthy counterparties. If, for any reason, any of the counterparties under these agreements do not fulfill their related contractual obligations, and we are unable to mitigate non-performance by a key supplier or maintenance provider or remarket PSA energy resulting in similar revenue, our financial position, results of operations and cash flows could be adversely affected. BNI Energy may be adversely impacted by its exposure to customer concentration, and environmental laws and regulations. BNI Energy sells lignite coal to two electric generating cooperatives, Minnkota Power and Square Butte, and could be adversely impacted if these customers were unable or unwilling to fulfill their related contractual obligations, or change the way in which they operate their generating facilities. In addition, BNI Energy and its customers may be adversely impacted by existing or new environmental laws and regulations which could have an adverse effect on our financial position, results of operations and cash flows. In addition, insurance companies have decreased the available coverage for policy holders in the mining industry, impacting the availability of coverage, and leading to higher deductibles and premiums. Real estate market conditions where our legacy Florida real estate investment is located may deteriorate. The Company’s strategy related to the real estate assets of ALLETE Properties incorporates the possibility of a bulk sale of its entire portfolio, in addition to sales over time, however, adverse market conditions could impact the timing of land sales, which could result in little to no sales, while still incurring operating expenses such as community development district assessments and property taxes, resulting in net operating losses at ALLETE Properties. Furthermore, weak market conditions could put the properties at risk for an impairment charge. An impairment charge would result in a non-cash charge to earnings that could have an adverse effect on our results of operations. Entity-wide Risks We could be materially adversely affected by health epidemics, pandemics and other outbreaks, such as the ongoing COVID-19 pandemic. The ongoing COVID-19 pandemic has resulted in widespread impacts on the global economy and on our employees, customers, contractors, and suppliers. There is considerable uncertainty regarding the length of time for which COVID-19 will continue, if new variants will emerge or the extent and duration of measures to try to contain the virus. We are responding to the COVID-19 pandemic by taking steps to mitigate the potential risks to us posed by its transmission and have implemented company-wide business continuity plans in response to the pandemic. These plans guide our emergency response, business continuity, and the precautionary measures we are taking on behalf of employees and the public. We have taken additional precautions for our employees who work in the field and for employees who continue to work in our facilities, and we have implemented work from home policies where appropriate. We continue to implement physical and cyber-security measures to ensure that our systems remain functional in order to both serve our operational needs with a remote workforce and keep them running to ensure uninterrupted service to our customers. The ongoing COVID-19 pandemic and related federal and state government responses has led to a disruption of economic activity, and could result in an extended disruption of economic activity. Further disruption of economic activity or an extended disruption of economic activity may lead to additional adverse impacts on our taconite, paper, pulp and secondary wood products, and pipeline customers’ operations including reduced production or the temporary idling or indefinite shutdown of facilities, which would result in lower sales and revenue from these customers. ALLETE, Inc. 2021 Form 10-K 30 Item 1A. Risk Factors (Continued) Entity-wide Risks (Continued) The Company is monitoring the capital markets and has access to liquidity to enable us to operate our businesses and fund capital projects; however, a disruption in capital markets could lead to increased borrowing costs or adversely impact our ability to access capital markets or other financing sources. If we are not able to access capital on acceptable terms in sufficient amounts and when needed, or at all, the ability to maintain our businesses or to implement our business plans would be adversely affected. In addition, the performance of capital markets impacts the values of the assets that are held in trust to satisfy future obligations under our pension and other postretirement benefit plans. A decline in the market value of these assets would increase the funding requirements under our benefit plans and future costs recognized for the benefit plans if the asset market values do not recover. The Company is also monitoring supply chains for key materials, supplies, labor and services for our operations and large capital projects. The pandemic could result in a disruption to our supply chains which could adversely impact our operations and capital projects. There has been some impact on our supply chains as to the availability of and price for materials, supplies and services to date. In addition, disruptions in our supply chains or a lack of available financing could jeopardize our ability to complete certain capital projects in time to qualify them for production tax credits. We will continue to monitor developments affecting our workforce, operations and customers, and we will take additional precautions that we determine are necessary in order to mitigate the impacts of the COVID-19 pandemic. Despite our efforts to manage these impacts to the Company, their ultimate impact also depends on factors beyond our control, including the duration and severity of this pandemic as well as governmental and third-party actions taken to contain its spread and mitigate its public health effects. As a result, we cannot predict the ultimate impact of the COVID-19 pandemic and whether it will have a material impact on our liquidity, financial position, results of operations and cash flows. We rely on access to financing sources and capital markets. If we do not have access to capital on acceptable terms or are unable to obtain capital when needed, our ability to execute our business plans, make capital expenditures or pursue other strategic actions that we may otherwise rely on for future growth would be adversely affected. We rely on access to financing sources and the capital markets, on acceptable terms and at reasonable costs, as sources of liquidity for capital requirements not satisfied by our cash flows from operations. Market disruptions or a downgrade of our credit ratings may increase the cost of borrowing or adversely affect our ability to access and finance in the capital markets or to access other financing sources such as tax equity financing. Such disruptions or causes of a downgrade could include but are not limited to: weakening of the Company’s cash flow metrics; a loss of, or a reduction in sales to, our taconite, paper and pipeline customers if we are unable to offset the related lost margins; weaker operating performance; adverse regulatory outcomes; disproportionate increase in the contribution to net income from ALLETE Clean Energy and our Corporate and Other businesses as compared to that from our Regulated Operations; deteriorating economic or capital market conditions; or volatility in commodity prices. If we are not able to access capital on acceptable terms in sufficient amounts and when needed, or at all, the ability to maintain our businesses or to implement our business plans would be adversely affected. A deterioration in general economic conditions, an inflationary environment or supply chain disruptions may have adverse impacts on our financial position, results of operations and cash flows. If economic conditions deteriorate, we experience an inflationary environment or supply chains are disrupted on a national or regional level, it may have a negative impact on the Company’s financial position, results of operations and cash flows as well as on our customers. This impact may include volatility and unpredictability in the demand for the products and services offered by our businesses, the loss of existing customers, tempered growth strategies, customer production cutbacks, customer bankruptcies and increases in costs for or limited availability of key materials, supplies, labor and services for our operations and capital projects. An uncertain economy could also adversely affect expenses including pension costs, interest costs, and uncollectible accounts, or lead to reductions in the value of certain real estate and other investments. ALLETE, Inc. 2021 Form 10-K 31 Item 1A. Risk Factors (Continued) Entity-wide Risks (Continued) Our businesses, investments and customers are subject to extensive state and federal legislation and regulation, compliance with which could have an adverse effect on our businesses. Our businesses, investments and customers are subject to, and affected by, extensive state and federal legislation and regulation. If it was determined that our businesses failed to comply with applicable laws and regulations, we could become subject to fines or penalties or be required to implement additional compliance measures or actions, the cost of which could be material. Adoption of new laws, rules, regulations, principles, or practices by federal and state agencies, or changes to or a failure to comply with current laws, rules, regulations, principles, or practices and their interpretations, could have an adverse effect on our financial position, results of operations and cash flows. The inability to attract and retain a qualified workforce including, but not limited to, executive officers, key employees and employees with specialized skills, could have an adverse effect on our operations. The success of our business heavily depends on the leadership of our executive officers and key employees to implement our business strategy. The inability to maintain a qualified workforce including, but not limited to, executive officers, key employees and employees with specialized skills, may negatively affect our ability to service our existing or new customers, or successfully manage our business or achieve our business objectives. Personnel costs may increase due to competitive pressures, inflation or terms of collective bargaining agreements with union employees. Market performance and other changes could decrease the value of pension and other postretirement benefit plan assets, which may result in significant additional funding requirements and increased annual expenses. The performance of the capital markets impacts the values of the assets that are held in trust to satisfy future obligations under our pension and other postretirement benefit plans. We have significant obligations to these plans and the trusts hold significant assets. These assets are subject to market fluctuations and will yield uncertain returns, which may fall below our projected rates of return. A decline in the market value of the pension and other postretirement benefit plan assets would increase the funding requirements under our benefit plans if asset returns do not recover. Additionally, our pension and other postretirement benefit plan liabilities are sensitive to changes in interest rates. As interest rates decrease, the liabilities increase, potentially increasing benefit expense and funding requirements. Our pension and other postretirement benefit plan costs are generally recoverable in our electric rates as allowed by our regulators or through our cost-plus fixed fee coal supply agreements at BNI Energy; however, there is no certainty that regulators will continue to allow recovery of these rising costs in the future. We are exposed to significant reputational risk. The Company could suffer negative impacts to its reputation as a result of operational incidents, violations of corporate compliance policies, regulatory violations, or other events which may result in negative customer perception and increased regulatory oversight, each of which could have an adverse effect on our financial position, results of operations and cash flows. We are subject to physical and financial risks associated with climate change and other catastrophic events, such as natural disasters and acts of war. Catastrophic events at or near Company facilities and equipment on which the Company depends upon or that otherwise impact the Company such as fires, wildfires, including the impact to Company facilities and operations or potential liability if caused by Company equipment, earthquakes, explosions, and floods, severe weather, such as ice storms, hailstorms, or tornadoes or similar occurrences, as well as acts of war, could adversely affect the Company’s facilities, operations, financial position, results of operations and cash flows. Although the Company has contingency plans and employs crisis management to respond and recover operations in the event of a severe disruption resulting from a catastrophic event, these measures may not be successful. Furthermore, despite these measures, if a catastrophic event were to occur, our financial position, results of operations and cash flows could be adversely affected. ALLETE, Inc. 2021 Form 10-K 32 Item 1A. Risk Factors (Continued) Entity-wide Risks (Continued) The scientific community generally accepts that emissions of GHG are linked to global climate change. Physical risks of climate change, such as more frequent, longer duration or more extreme weather events, changes in temperature and precipitation patterns, changes to ground and surface water availability, and other related phenomena, could affect some, or all, of our operations. Severe weather or other natural disasters could be destructive, which could result in increased costs or limit the availability of key materials, supplies, labor and services. An extreme weather event can also directly affect our capital assets, causing disruption in service to customers due to facility outages, downed wires and poles or damage to other operating equipment. Climate-related risks that could adversely affect our financial position and results of operations include effects of environmental- or economic-based laws, regulations, incentives or initiatives designed to reduce the quantity or impact of GHG emissions. This includes the risk of laws or regulations that create mandates that do not allow for a transition that protects the safety, reliability or affordability of energy for our customers, are implemented before cost- effective technology is developed and regulatory policy is established, or require the electric sector to decarbonize faster than other sectors and ahead of our current goal to deliver 100 percent carbon-free energy to customers by 2050. Additionally, restrictions on land use, wildlife impacts, and other environmental regulations could affect the siting, construction and operation of new or existing generation and transmission facilities needed to transition to lower-carbon generation sources. These all have the potential to adversely affect our business and operations. We are vulnerable to acts of terrorism or cybersecurity attacks. Our operations may be targets of terrorist activities or cybersecurity attacks, which could disrupt our ability to provide utility service at our regulated utilities, develop or operate our renewable energy projects at ALLETE Clean Energy, or operate our other businesses. The impacts may also impair the fulfillment of critical business functions, negatively impact our reputation, subject us to litigation or increased regulation, or compromise sensitive, confidential and other data. There have been cybersecurity attacks on U.S. energy infrastructure in the past and there may be such attacks in the future. Our generation, transmission and distribution facilities, information technology systems and other infrastructure facilities and systems could be direct targets of, or otherwise be materially adversely affected by such activities. Hacking, computer viruses, terrorism, theft and sabotage could impact our systems and facilities, or those of third parties on which we rely, which may disrupt our operations. Our businesses require the continued operation of sophisticated custom-developed, purchased, and leased information technology systems and network infrastructure as well as the collection and retention of personally identifiable information of our customers, shareholders and employees. Although we maintain security measures designed to prevent cybersecurity incidents and protect our information technology and control systems, network infrastructure and other assets, our technology systems, or those of third parties on which we rely, may be vulnerable to disability, failures or unauthorized access due to hacking, viruses, acts of war or terrorism as well as other causes. If those technology systems fail or are breached and not recovered in a timely manner, we may be unable to perform critical business functions including effectively maintaining certain internal controls over financial reporting, our reputation may be negatively impacted, we may become subject to litigation or increased regulation, and sensitive, confidential and other data could be compromised. If our business were impacted by terrorist activities or cybersecurity attacks, such impacts could have an adverse effect on our financial position, results of operations and cash flows. We maintain insurance against some, but not all, of the risks and uncertainties we face. We maintain insurance against some, but not all, of the risks and uncertainties we face. The occurrence of these risks and uncertainties, if not fully covered by insurance, could have a material effect on our financial position, results of operations and cash flows. ALLETE, Inc. 2021 Form 10-K 33 Item 1A. Risk Factors (Continued) Entity-wide Risks (Continued) Government challenges to our tax positions, as well as tax law changes and the inherent difficulty in quantifying potential tax effects of our operations and business decisions, could adversely affect our results of operations and liquidity. We are required to make judgments regarding the potential tax effects of various financial transactions and our ongoing operations in order to estimate our obligations to taxing authorities. The obligations, which include income taxes and taxes other than income taxes, involve complex matters that ultimately could be litigated. We also estimate our ability to use tax benefits, including those in the form of carryforwards and tax credits that are recorded as deferred tax assets on our Consolidated Balance Sheet. A disallowance of some or all of these tax benefits could have an adverse impact on our financial position, results of operations and cash flows. We are currently utilizing, and plan to utilize in the future, our carryforwards and tax credits to reduce our income tax obligations. If we cannot generate enough taxable income in the future to utilize all of our carryforwards and tax credits before they expire, we may incur adverse charges to earnings. If federal or state tax authorities deny any deductions or tax credits, negatively change existing tax laws or policies, or fail to extend or renew policies beneficial to the Company, such as those for renewable energy production tax credits, our financial position, results of operations and cash flows may be adversely impacted. Item 1B. Unresolved Staff Comments None. Item 2. Properties A discussion of our properties is included in Item 1. Business and is incorporated by reference herein. Item 3. Legal Proceedings Discussions of material regulatory and environmental proceedings are included in Note 4. Regulatory Matters and Note 8. Commitments, Guarantees and Contingencies, and are incorporated by reference herein. We are involved in litigation arising in the normal course of business. Also in the normal course of business, we are involved in tax, regulatory and other governmental audits, inspections, investigations and other proceedings that involve state and federal taxes, safety, and compliance with regulations, rate base and cost of service issues, among other things. We do not expect the outcome of these matters to have a material effect on our financial position, results of operations or cash flows. Minnesota Power has been named in a lawsuit where a contractor performing work at one of its facilities experienced an injury and subsequently filed a lawsuit seeking compensatory damages. Litigation related to this injury is ongoing. At this time, a loss is considered reasonably possible; however, we do not deem it probable, and we are unable to estimate a loss or range of loss related to the litigation at this time. Item 4. Mine Safety Disclosures The Dodd-Frank Wall Street Reform and Consumer Protection Act (Dodd-Frank Act) requires issuers to include in periodic reports filed with the SEC certain information relating to citations or orders for violations of standards under the Federal Mine Safety and Health Act of 1977 (Mine Safety Act). Information concerning mine safety violations or other regulatory matters required by Section 1503(a) of the Dodd-Frank Act and this Item are included in Exhibit 95 to this Form 10-K.

A quarterly dividend of $0.65 per share on our common stock is payable on March 1, 2022, to the shareholders of record on February 15, 2022. The timing and amount of future dividends will depend upon earnings, cash requirements, the financial condition of the Company, applicable government regulations and other factors deemed relevant by the ALLETE Board of Directors. As of February 1, 2022, there were approximately 20,000 common stock shareholders of record. Performance Graph. The following graph compares ALLETE’s cumulative Total Shareholder Return on its common stock with the cumulative return of the S&P 500 Index and the Philadelphia Utility Index. The S&P 500 Index is a capitalization-weighted index of 500 stocks designed to measure performance of the broad domestic economy through changes in the aggregate market value of 500 stocks representing all major industries. Because this composite index has a broad industry base, its performance may not closely track that of a composite index comprised solely of electric utilities. The Philadelphia Utility Index is a capitalization-weighted index of 20 utility companies involved in the generation of electricity. The calculations assume a $100 investment on December 31, 2016, and reinvestment of dividends.

Our business, financial condition or results of operations could suffer if the risks are realized. The trends and results for the year ended December 31, 2021, may not be indicative of future results that may be expected due to uncertainty regarding the COVID-19 pandemic. This pandemic has resulted in widespread impacts on the global economy and on our employees, customers, contractors, and suppliers. There is considerable uncertainty regarding the length of time for which COVID-19 will continue, if new variants will emerge or the extent and duration of measures to try to contain the virus. Additional disclosures in this Form 10-K regarding the impacts of the ongoing COVID-19 pandemic are located in Item 1A. Risk Factors. Overview Basis of Presentation. We present three reportable segments: Regulated Operations, ALLETE Clean Energy and U.S. Water Services. Our segments were determined in accordance with the guidance on segment reporting. We measure performance of our operations through budgeting and monitoring of contributions to consolidated net income by each business segment. Regulated Operations includes our regulated utilities, Minnesota Power and SWL&P, as well as our investment in ATC, a Wisconsin-based regulated utility that owns and maintains electric transmission assets in portions of Wisconsin, Michigan, Minnesota and Illinois. Minnesota Power provides regulated utility electric service in northeastern Minnesota to approximately 150,000 retail customers. Minnesota Power also has 15 non-affiliated municipal customers in Minnesota. SWL&P is a Wisconsin utility and a wholesale customer of Minnesota Power. SWL&P provides regulated utility electric, natural gas and water service in northwestern Wisconsin to approximately 15,000 electric customers, 13,000 natural gas customers and 10,000 water customers. Our regulated utility operations include retail and wholesale activities under the jurisdiction of state and federal regulatory authorities. (See Note 4. Regulatory Matters.) ALLETE Clean Energy focuses on developing, acquiring, and operating clean and renewable energy projects. ALLETE Clean Energy currently owns and operates, in seven states, more than 1,300 MW of nameplate capacity wind energy generation that is contracted under PSAs of various durations. In addition, ALLETE Clean Energy currently has approximately 200 MW of wind energy facilities under contract to be sold to others. ALLETE Clean Energy also engages in the development of wind energy facilities to operate under long-term PSAs or for sale to others upon completion. U.S. Water Services provided integrated water management for industry by combining chemical, equipment, engineering and service for customized solutions to reduce water and energy usage, and improve efficiency. In March 2019, the Company sold U.S. Water Services to a subsidiary of Kurita Water Industries Ltd. Corporate and Other is comprised of BNI Energy, our coal mining operations in North Dakota; our investment in Nobles 2, an entity that owns and operates a 250 MW wind energy facility in southwestern Minnesota; South Shore Energy, our non-rate regulated, Wisconsin subsidiary developing NTEC, an approximately 600 MW proposed combined-cycle natural gas-fired generating facility; ALLETE Properties, our legacy Florida real estate investment; other business development and corporate expenditures; unallocated interest expense; a small amount of non-rate base generation; approximately 4,000 acres of land in Minnesota; and earnings on cash and investments. ALLETE, Inc. 2021 Form 10-K 36 Overview (Continued) ALLETE is incorporated under the laws of Minnesota. Our corporate headquarters are in Duluth, Minnesota. Statistical information is presented as of December 31, 2021, unless otherwise indicated. All subsidiaries are wholly-owned unless otherwise specifically indicated. References in this report to “we,” “us” and “our” are to ALLETE and its subsidiaries, collectively. 2021 Financial Overview The following net income discussion summarizes a comparison of the year ended December 31, 2021 to the year ended December 31, 2020. The trends and results for the year ended December 31, 2021 may not be indicative of future results due to uncertainty regarding the COVID-19 pandemic. (See Overview.) Net income attributable to ALLETE in 2021 was $169.2 million, or $3.23 per diluted share, compared to $174.2 million, or $3.35 per diluted share, in 2020. Net income in 2021 included South Shore Energy’s sale of a portion of its interest in NTEC to Basin Electric Cooperative. The closing of the transaction between South Shore Energy and Basin resulted in the recognition of an approximately $8.5 million after-tax gain, or $0.16 per share, related to prior development costs and risks incurred. Net income in 2021 also included an approximately $5 million after-tax, or $0.10 per share, negative impact related to ALLETE Clean Energy’s Diamond Spring wind energy facility due to an extreme winter storm event in the southwest United States in February 2021. This winter storm event caused volatility in power prices in the regional power market resulting in losses being incurred under one of the facility’s power sales agreements during portions of the winter storm event. Additionally, net income in 2021 included a $3.6 million after-tax, or $0.07 per share, charge resulting from the MPUC’s decision to order refunds in Minnesota Power’s fuel adjustment clause filing covering the period July 2018 through December 2019. Net income in 2020 included margins of $10.2 million after-tax, or $0.20 per share, in Regulated Operations for sales under a 100 MW PSA which expired in April 2020. Net income in 2020 also included reserves for interim rates of $8.3 million after-tax, or $0.16 per share, for the refund of interim rates collected between January 1, 2020, and April 30, 2020. Earnings per share dilution in 2021 was $0.03 due to additional shares of common stock outstanding as of December 31, 2021. Regulated Operations net income attributable to ALLETE was $129.1 million in 2021, compared to $136.3 million in 2020. Net income at Minnesota Power was lower than 2020 primarily due to: lower margins from Other Power Suppliers resulting primarily from the expiration of a PSA; higher operating and maintenance, property tax and depreciation expenses; and a reserve for refunds resulting from the MPUC’s decision to order refunds in Minnesota Power’s fuel adjustment clause filing covering the period July 2018 through December 2019. These negative impacts were partially offset by increased earnings related to the GNTL; and higher kWh sales to retail and municipal customers. Net income in 2020 also included reserves for interim rates of $8.3 million after-tax for the refund of interim rates collected between January 1, 2020, and April 30, 2020. Net income at SWL&P was lower than 2020 primarily due to higher operating expenses. Our after-tax equity earnings in ATC were lower compared to 2020 primarily due to period over period changes in ATC’s estimate of a refund liability related to the FERC decision on MISO return on equity complaints in 2020. ALLETE Clean Energy net income attributable to ALLETE was $26.3 million in 2021 compared to $29.9 million in 2020. Net income in 2021 included an approximately $5 million after-tax negative impact related to ALLETE Clean Energy’s Diamond Spring wind energy facility due to an extreme winter storm event in the southwest United States in February 2021 as well as lower wind resources at other wind energy facilities. These negative impacts were partially offset by expense management efforts. Corporate and Other net income attributable to ALLETE was $13.8 million in 2021 compared to $8.0 million in 2020. Net income in 2021 included South Shore Energy’s sale of a portion of its interest in NTEC to Basin Electric Cooperative which resulted in the recognition of an approximately $8.5 million after-tax gain related to prior development costs and risks incurred, higher earnings from our investment in Nobles 2 which commenced operations in December 2020 and higher land sales at ALLETE Properties. These increases were partially offset by higher expenses. ALLETE, Inc. 2021 Form 10-K 37 2021 Compared to 2020 (See Note 13. Business Segments for financial results by segment.) Regulated Operations Year Ended December 31 Millions Operating Revenue – Utility Fuel, Purchased Power and Gas – Utility Transmission Services – Utility Operating and Maintenance Depreciation and Amortization Taxes Other than Income Taxes Operating Income Interest Expense Equity Earnings Other Income Income Before Income Taxes Income Tax Benefit Net Income Attributable to ALLETE 2021 2020 $1,227.9 562.4 75.3 216.0 170.7 60.9 142.6 (57.3) 21.3 5.9 112.5 (16.6) $129.1 $987.3 358.6 67.0 200.9 166.9 50.7 143.2 (58.5) 22.3 9.9 116.9 (19.4) $136.3 Operating Revenue – Utility increased $240.6 million from 2020 primarily due to higher fuel adjustment clause recoveries, higher kWh sales, increased transmission-related revenue related to the GNTL, higher cost recovery rider revenue and higher FERC formula-based rates. Revenue in 2020 also included reserves for the refund of interim rates collected between January 1, 2020, and April 30, 2020. Fuel adjustment clause revenue increased $121.3 million due to higher fuel and purchased power costs attributable to retail and municipal customers. (See Fuel, Purchased Power and Gas – Utility.) These increases were partially offset by a $5 million charge resulting from the MPUC’s decision to order refunds in Minnesota Power’s fuel adjustment clause filing covering the period July 2018 through December 2019. (See Note 4. Regulatory Matters.) Revenue from kWh sales increased $67.6 million from 2020 primarily due to higher sales to commercial and industrial customers as well as other power suppliers. These increases were partially offset by lower revenue related to the expiration of a 100 MW PSA in April 2020. Sales to commercial and industrial customers increased primarily due to improving business conditions related to the COVID-19 pandemic and its impact on customer operations. Many commercial and industrial customers operated at reduced levels or were temporarily closed or idled during 2020 as a result of the COVID-19 pandemic and related governmental responses while business conditions improved in 2021. These higher sales to commercial and industrial customers were partially offset by lower sales to and demand revenue from Verso Corporation which indefinitely idled its paper mill in Duluth, Minnesota in 2020. (See Outlook – Regulated Operations – Industrial Customers and Prospective Additional Load.) Sales to other power suppliers, which are sold at market-based prices into the MISO market on a daily basis or through PSAs of various durations, increased primarily due to additional kWh sales made to mitigate the uncertainty of customers’ energy needs and potential load loss due to the COVID-19 pandemic. Kilowatt-hours Sold Millions Regulated Utility Retail and Municipal Residential Commercial Industrial Municipal Total Retail and Municipal Other Power Suppliers Total Regulated Utility Kilowatt-hours Sold 2021 2020 Quantity Variance % Variance 1,135 1,359 7,196 590 10,280 5,102 15,382 1,134 1,306 6,192 584 9,216 4,039 13,255 1 53 1,004 6 1,064 1,063 2,127 0.1 4.1 16.2 1.0 11.5 26.3 16.0 ALLETE, Inc. 2021 Form 10-K 38 2021 Compared to 2020 (Continued) Regulated Operations (Continued) Revenue from electric sales to taconite customers accounted for 33 percent of regulated operating revenue in 2021 (30 percent in 2020). Revenue from electric sales to paper, pulp and secondary wood product customers accounted for 5 percent of regulated operating revenue in 2021 (5 percent in 2020). Revenue from electric sales to pipelines and other industrial customers accounted for 9 percent of regulated operating revenue in 2021 (9 percent in 2020). Transmission-related revenue increased $17.7 million primarily due to recovery of GNTL expenses resulting from the GNTL being placed into service in June 2020. Revenue in 2020 included reserves of $11.7 million for the refund of interim rates collected between January 1, 2020, and April 30, 2020. (See Note 2. Regulatory Matters.) Cost recovery rider revenue increased $9.0 million primarily due to fewer production tax credits recognized by Minnesota Power. If production tax credits are recognized at a level below those assumed in Minnesota Power’s base rates, an increase in cost recovery rider revenue is recognized to offset the impact of lower production tax credits on income tax expense. Revenue from wholesale customers under FERC formula-based rates increased $5.2 million primarily due to higher rates. Operating Expenses increased $241.2 million, or 29 percent, from 2020. Fuel, Purchased Power and Gas – Utility expense increased $203.8 million, or 57 percent, from 2020 primarily due to higher purchased power prices, kWh sales and fuel costs. Fuel and purchased power expense related to our retail and municipal customers is recovered through the fuel adjustment clause. Transmission Services – Utility expense increased $8.3 million, or 12 percent, from 2020 primarily due to higher MISO-related expense. Operating and Maintenance expense increased $15.1 million, or 8 percent, from 2020 primarily due to an increase in contract and professional services and materials purchased for generation facilities and higher vegetation management expenses. In addition, 2021 included higher labor and benefit expenses as compared to 2020. Depreciation and Amortization expense increased $3.8 million, or 2 percent, from 2020 primarily due to additional property, plant and equipment in service resulting from the GNTL being placed into service in June 2020. Taxes Other than Income Taxes increased $10.2 million, or 20 percent, from 2020 primarily due to higher property tax expense resulting from the GNTL being placed into service in June 2020 as well as higher estimated taxable market values. Other Income decreased $4.0 million from 2020 primarily due to lower pension and other postretirement plan non-service credits. (See Note 1. Operations and Significant Accounting Policies.) Income Tax Benefit decreased $2.8 million from 2020 primarily due to fewer production tax credits in 2021 compared to 2020, partially offset by lower pre-tax income.

Year Ended December 31, Production and Operating Revenue Millions Wind Energy Regions East Midwest South West Total Production and Operating Revenue 2021 2020 kWh Revenue kWh Revenue 236.6 882.9 1,009.8 823.2 2,952.5 $21.4 32.2 11.2 22.1 $86.9 262.2 902.0 169.1 777.5 2,110.8 $23.5 32.2 3.9 20.0 $79.6 Cost of Sales increased $3.0 million from 2020 due to a reserve for an anticipated loss on sale of ALLETE Clean Energy’s project to repower and sell its Northern Wind project. (See Outlook – ALLETE Clean Energy.) Operating and Maintenance expense increased $4.1 million, or 11 percent, from 2020 primarily due to operating and maintenance expenses related to the South Peak and Diamond Spring wind energy facilities as well as expense related to the Caddo wind energy facility which commenced operations in December 2021. These increases were offset by expense management efforts. Depreciation and Amortization expense increased $11.3 million, or 30 percent, from 2020 primarily due to additional property, plant and equipment in service related to the South Peak and Diamond Spring wind energy facilities. Taxes Other Than Income Taxes increased $3.8 million from 2020 primarily due to higher property tax expense related to the Diamond Spring wind energy facility. Income Tax Benefit decreased $2.5 million from 2020 primarily due to less production tax credits generated in 2021. ALLETE, Inc. 2021 Form 10-K 40 2021 Compared to 2020 (Continued) ALLETE Clean Energy (Continued) Net Loss Attributable to Non-Controlling Interest increased $13.0 million from 2020 primarily due to net losses attributable to non-controlling interest for the Diamond Spring wind energy facility. Corporate and Other Operating Revenue increased $2.2 million, or 2 percent, from 2020 primarily due to higher land sales at ALLETE Properties in 2021, partially offset by lower revenue at BNI Energy, which operates under cost-plus fixed fee contracts, as a result of lower expenses and fewer tons sold in 2021 compared to 2020. Net Income Attributable to ALLETE was $13.8 million in 2021 compared to $8.0 million in 2020. Net income in 2021 included South Shore Energy’s sale of a portion of its interest in NTEC to Basin Electric Cooperative which resulted in the recognition of an approximately $8.5 million after-tax gain related to prior development costs and risks incurred, higher earnings from our investment in Nobles 2 which commenced operations in December 2020 and higher land sales at ALLETE Properties. These increases were partially offset by higher expenses. Net income at BNI Energy was $7.5 million in 2021 compared to net income of $7.3 million in 2020. Net income at ALLETE Properties was $1.9 million in 2021 compared to net income of $0.4 million in 2020. Income Taxes – Consolidated For the year ended December 31, 2021, the effective tax rate was a benefit of 24.3 percent (benefit of 32.4 percent for the year ended December 31, 2020). The effective tax rate for 2021 was a lower benefit primarily due to fewer production tax credits generated in 2021. (See Note 10. Income Tax Expense.) 2020 Compared to 2019 The comparison of the results of operations for the years ended December 31, 2020 and 2019 is included in Management's Discussion in the Annual Report on Form 10-K for the year ended December 31, 2020. Critical Accounting Policies The preparation of financial statements and related disclosures in conformity with GAAP requires management to make various estimates and assumptions that affect amounts reported in the Consolidated Financial Statements. These estimates and assumptions may be revised, which may have a material effect on the Consolidated Financial Statements. Actual results may differ from these estimates and assumptions. These policies are discussed with the Audit Committee of our Board of Directors on a regular basis. We believe the following policies are most critical to our business and the understanding of our results of operations. Regulatory Accounting. Our regulated utility operations are subject to accounting standards for the effects of certain types of regulation. These standards require us to reflect the effect of regulatory decisions in our financial statements. Regulatory assets represent incurred costs that have been deferred as they are probable for recovery in customer rates. Regulatory liabilities represent obligations to make refunds to customers and amounts collected in rates for which the related costs have not yet been incurred. The Company assesses quarterly whether regulatory assets and liabilities meet the criteria for probability of future recovery or deferral. This assessment considers factors such as, but not limited to, changes in the regulatory environment and recent rate orders to other regulated entities under the same jurisdiction. If future recovery or refund of costs becomes no longer probable, the assets and liabilities would be recognized in current period net income or other comprehensive income. (See Note 4. Regulatory Matters.) ALLETE, Inc. 2021 Form 10-K 41 Critical Accounting Policies (Continued) Pension and Postretirement Health and Life Actuarial Assumptions. We account for our pension and other postretirement benefit obligations in accordance with the accounting standards for defined benefit pension and other postretirement plans. These standards require the use of several important assumptions, including the expected long-term rate of return on plan assets, the discount rate and mortality assumptions, among others, in determining our obligations and the annual cost of our pension and other postretirement benefits. In establishing the expected long-term rate of return on plan assets, we determine the long-term historical performance of each asset class and adjust these for current economic conditions while utilizing the target allocation of our plan assets to forecast the expected long-term rate of return. Our pension asset allocation as of December 31, 2021, was approximately 49 percent equity securities, 48 percent fixed income and 3 percent real estate. Our postretirement health and life asset allocation as of December 31, 2021, was approximately 70 percent equity securities, 29 percent fixed income and 1 percent private equity. Equity securities consist of a mix of market capitalization sizes with domestic and international securities. In 2021, we used weighted average expected long-term rates of return of 6.50 percent in our actuarial determination of our pension expense and 5.85 percent in our actuarial determination of our other postretirement expense. The actuarial determination uses an asset smoothing methodology for actual returns to reduce the volatility of varying investment performance over time. We review our expected long-term rate of return assumption annually and will adjust it to respond to changing market conditions. A one-quarter percent decrease in the expected long-term rate of return would increase the annual expense for pension and other postretirement benefits by approximately $2.0 million, pre-tax. The discount rate is computed using a bond matching study which utilizes a portfolio of high quality bonds that produce cash flows similar to the projected costs of our pension and other postretirement plans. In 2021, we used weighted average discount rates of 2.87 percent and 2.70 percent in our actuarial determination of our pension and other postretirement expense, respectively. We review our discount rates annually and will adjust them to respond to changing market conditions. A one-quarter percent decrease in the discount rate would increase the annual expense for pension and other postretirement benefits by approximately $1.7 million, pre-tax. The mortality assumptions used to calculate our pension and other postretirement benefit obligations as of December 31, 2021, considered a modified PRI- 2012 mortality table and MP-2021 mortality projection scale. (See Note 11. Pension and Other Postretirement Benefit Plans.) Impairment of Long-Lived Assets. We review our long-lived assets for indicators of impairment in accordance with the accounting standards for property, plant and equipment on a quarterly basis. In accordance with the accounting standards for property, plant and equipment, if indicators of impairment exist, we test our long‑lived assets for recoverability by comparing the carrying amount of the asset to the undiscounted future net cash flows expected to be generated by the asset. Cash flows are assessed at the lowest level of identifiable cash flows. The undiscounted future net cash flows are impacted by trends and factors known to us at the time they are calculated and our expectations related to: management’s best estimate of future sales prices; holding period and timing of sales; method of disposition; and future expenditures necessary to maintain the operations. Taxation. We are required to make judgments regarding the potential tax effects of various financial transactions and our ongoing operations to estimate our obligations to taxing authorities. These tax obligations include income taxes and taxes other than income taxes. Judgments related to income taxes require the recognition in our financial statements of the largest tax benefit of a tax position that is “more-likely-than-not” to be sustained on audit. Tax positions that do not meet the “more-likely-than-not” criteria are reflected as a tax liability in accordance with the accounting standards for uncertainty in income taxes. We record a valuation allowance against our deferred tax assets to the extent it is more-likely-than-not that some portion or all of the deferred tax assets will not be realized. We are subject to income taxes in various jurisdictions. We make assumptions and judgments each reporting period to estimate our income tax assets, liabilities, benefits and expenses. Judgments and assumptions are supported by historical data and reasonable projections. Our assumptions and judgments include the application of tax statutes and regulations, and projections of future federal taxable income, state taxable income, and state apportionment to determine our ability to utilize NOL and credit carryforwards prior to their expiration. Significant changes in assumptions regarding future federal and state taxable income or a change in tax rates could require new or increased valuation allowances which could result in a material impact on our results of operations. ALLETE, Inc. 2021 Form 10-K 42 Outlook ALLETE is an energy company committed to earning a financial return that rewards our shareholders, allows for reinvestment in our businesses, and sustains growth. The Company has a long-term objective of achieving consolidated average annual earnings per share growth within a range of 5 percent to 7 percent. ALLETE is predominately a regulated utility through Minnesota Power, SWL&P, and an investment in ATC. ALLETE’s strategy is to remain predominately a regulated utility while investing in ALLETE Clean Energy and its Corporate and Other businesses to complement its regulated businesses, balance exposure to the utility’s industrial customers, and provide potential long-term earnings growth. ALLETE expects net income from Regulated Operations to be approximately 75 percent of total consolidated net income in 2022. Over the next several years, the contribution of ALLETE Clean Energy and our Corporate and Other businesses to net income is expected to increase as ALLETE grows these operations. ALLETE expects its businesses to provide regulated, contracted or recurring revenues, and to support sustained growth in net income and cash flow. Regulated Operations. Minnesota Power’s long-term strategy is to be the leading electric energy provider in northeastern Minnesota by providing safe, reliable and cost-competitive electric energy, while complying with environmental permit conditions and renewable energy requirements. Keeping the cost of energy production competitive enables Minnesota Power to effectively compete in the wholesale power markets and minimizes retail rate increases to help maintain customer viability. As part of maintaining cost competitiveness, Minnesota Power intends to reduce its exposure to possible future carbon and GHG legislation by reshaping its generation portfolio, over time, to reduce its reliance on coal. Minnesota Power has a goal of delivering 100 percent carbon-free energy by 2050. (See EnergyForward.) We will monitor and review proposed environmental regulations and may challenge those that add considerable cost with limited environmental benefit. Minnesota Power will continue to pursue customer growth opportunities and cost recovery rider approvals for transmission, renewable and environmental investments, as well as work with regulators to earn a fair rate of return. Regulatory Matters. Entities within our Regulated Operations segment are under the jurisdiction of the MPUC, FERC, PSCW and NDPSC. See Note 4. Regulatory Matters for discussion of regulatory matters within these jurisdictions. 2022 Minnesota General Rate Case. On November 1, 2021, Minnesota Power filed a retail rate increase request with the MPUC seeking an average increase of approximately 18 percent for retail customers. The rate filing seeks a return on equity of 10.25 percent and a 53.81 percent equity ratio. On an annualized basis, the requested final rate increase would generate approximately $108 million in additional revenue. In orders dated December 30, 2021, the MPUC accepted the filing as complete and authorized an annual interim rate increase beginning January 1, 2022, with approximately $80 million expected to be collected in cash and approximately $8 million of interim rates for residential customers deferred with a final determination on recovery at the end of the rate case. Minnesota Power Land Sales. In August 2020, Minnesota Power filed a petition with the MPUC for approval to sell land that surrounds several reservoirs on its hydroelectric system and is no longer required to maintain its operations. The land has an estimated value of approximately $100 million, and Minnesota Power proposed to credit ratepayers the net proceeds from the sales in a future rate case or through its renewable resources rider to mitigate future rate increases. In an order dated November 18, 2021, the MPUC authorized the land sales and directed the net proceeds to be refunded to ratepayers subject to certain conditions and required compliance filings. Wisconsin General Rate Case. SWL&P expects to file its next general rate case in 2022. The PSCW granted an extension request made by SWL&P to delay filing its next general rate case until on or before December 20, 2022. SWL&P requested the extension primarily due to impacts of the COVID-19 pandemic. ALLETE, Inc. 2021 Form 10-K 43 Outlook (Continued) Industrial Customers and Prospective Additional Load Industrial Customers. Electric power is one of several key inputs in the taconite mining, paper, pulp and secondary wood products, pipeline and other industries. Approximately 47 percent of our regulated utility kWh sales in 2021 (47 percent in 2020 and 54 percent in 2019) were made to our industrial customers. We expect industrial sales of approximately 6.5 million MWh in 2022 (7.2 million MWh in 2021 and 6.2 million in 2020). (See Item 1. Business – Regulated Operations – Electric Sales / Customers.) Taconite. Minnesota Power’s taconite customers are capable of producing up to approximately 41 million tons of taconite pellets annually. Taconite pellets produced in Minnesota are primarily shipped to North American steel making facilities that are part of the integrated steel industry, which continue to lead the world in environmental performance among steelmaking countries. According to the U.S. Department of Energy, steel production in the U.S. is the most energy efficient of any major steel producing country. Steel produced from these North American facilities is used primarily in the manufacture of automobiles, appliances, tubular applications for all industries, and in the construction industry. Steel is also a critical component of the clean energy transformation underway today. Meeting the demand for more renewable energy and the need for additional infrastructure to transport green energy from the point of generation to the end user both require steel. Historically, less than 10 percent of Minnesota taconite production has been exported outside of North America. There has been a general historical correlation between U.S. steel production and Minnesota taconite production. The American Iron and Steel Institute, an association of North American steel producers, reported that U.S. raw steel production operated at approximately 82 percent of capacity in 2021 (68 percent in 2020 and 80 percent in 2019). The World Steel Association, an association of steel producers, national and regional steel industry associations, and steel research institutes representing approximately 85 percent of world steel production, projected U.S. steel consumption in 2022 will increase by approximately 6 percent compared to 2021. Minnesota Power’s taconite customers may experience annual variations in production levels due to such factors as economic conditions, short-term demand changes or maintenance outages. We expect taconite production from our taconite customers of approximately 35 million tons in 2022. We estimate that a one million ton change in Minnesota Power’s taconite customers’ production would impact our annual earnings per share by approximately $0.04, net of expected power marketing sales at current prices. Changes in wholesale electric prices or customer contractual demand nominations could impact this estimate. Minnesota Power proactively sells power in the wholesale power markets that is temporarily not required by industrial customers to optimize the value of its generating facilities. Long-term reductions in taconite production or a permanent shut down of a taconite customer may lead Minnesota Power to file a general rate case to recover lost revenue. USS Corporation. In April 2020, USS Corporation stated it would idle its Keetac facility in Keewatin, Minnesota, in response to the sudden and dramatic decline in business conditions resulting from the COVID-19 pandemic. In addition, in May 2020, USS Corporation announced that production was expected to be temporarily reduced at its Minntac Plant in Mountain Iron, Minnesota. USS Corporation resumed normal production at its Minntac Plant beginning in late July 2020 and resumed operations at its Keetac facility in December 2020. In October 2021, USS Corporation announced that it will be increasing its blast furnace operating rates at its Gary, Indiana steel mill through the installation of a 500,000 ton per year pig iron caster. When completed in early 2023, the pig iron produced from Minnesota iron ore would be used at USS Corporation’s Big River steel making facility in Osceola, Arkansas. USS Corporation has the capability to produce approximately 15 million and 5 million tons annually at its Minntac and Keetac plants, respectively. Cliffs. In December 2020, Cliffs announced that it had completed the previously announced acquisition of substantially all of the operations of ArcelorMittal USA LLC and its subsidiaries. Cliffs had stated that upon closure of the acquisition Cliffs would be the largest flat-rolled steel producer and the largest iron ore pellet producer in North America. The acquisition included ArcelorMittal’s Minorca mine in Virginia, Minnesota, and its ownership share of Hibbing Taconite in Hibbing, Minnesota, which are both large industrial customers of Minnesota Power. Cliffs is now Minnesota Power’s largest customer. The acquisition has increased customer concentration risk for the Company and could lead to further capacity consolidation for both steel blast furnaces and the related Minnesota iron ore production. Cliffs completed construction of a hot briquetted iron production plant in Toledo, Ohio, in 2020, which has utilized direct reduced-grade pellets from Northshore Mining. In October 2021, Cliffs indicated it plans to move direct reduced-grade pellet production to its Minorca mine and that Northshore Mining would become a “swing facility” due to the higher royalty rates at that mine. (See Northshore Mining.). ALLETE, Inc. 2021 Form 10-K 44 Outlook (Continued) Industrial Customers and Prospective Additional Load (Continued) Northshore Mining. In April 2020, Cliffs announced that, based on market conditions, it would be temporarily idling Northshore Mining. Cliffs idled production at Northshore Mining in April 2020 and resumed normal production at the facility in August 2020. On February 11, 2022, Cliffs announced that with the use of additional scrap in its basic oxygen furnaces, iron ore needs are not as high as before. When determining where to adjust production, Cliffs decided to idle all production at its Northshore mine. Cliffs anticipated that the Northshore mine will be temporarily idled for approximately four months during 2022. Cliffs also indicated that going forward it will be limiting the tonnage of iron ore pellets sold to third parties. Northshore Mining has the capability to produce approximately 6 million tons annually. Minnesota Power has a PSA through 2031 with Silver Bay Power, which provides the majority of the electric service requirements for Northshore Mining. (See Silver Bay Power and Cliffs.) Silver Bay Power. In 2016, Minnesota Power and Silver Bay Power entered into a PSA through 2031. Silver Bay Power supplies approximately 90 MW of load to Northshore Mining, an affiliate of Silver Bay Power, which had previously been served predominately through self-generation by Silver Bay Power. Starting in 2016, Minnesota Power supplied Silver Bay Power with at least 50 MW of energy and Silver Bay Power had the option to purchase additional energy from Minnesota Power as it transitioned away from self-generation. In the third quarter of 2019, Silver Bay Power ceased self-generation and Minnesota Power began supplying the full energy requirements for Silver Bay Power. Hibbing Taconite. In April 2020, ArcelorMittal announced that Hibbing Taconite in Hibbing, Minnesota, would idle production due to the COVID-19 pandemic. Hibbing Taconite resumed normal production in August 2020. Hibbing Taconite’s current mineable ore reserves are expected to be exhausted in 2025. Cliffs, which in December 2020 became majority owner and resumed management of Hibbing Taconite, has stated that it has a plan to extend the mine life of Hibbing Taconite with ore reserves already under control of Cliffs. There are ample ore reserves in northeastern Minnesota that could supply operations for decades to come, and Minnesota Power’s taconite customers routinely develop and extend their mine plans to optimize assets. Hibbing Taconite has the capability to produce approximately 8 million tons annually. Minnesota Sulfate Wild Rice Water Quality Standard. On April 29, 2021, the EPA identified rivers and lakes in Minnesota in which wild rice grows that have sulfate levels that exceed Minnesota’s sulfate limit for wild rice waters. On September 1, 2021, three additional wild rice waters with sulfate levels that exceed Minnesota’s sulfate limit were identified. The EPA directed the MPCA to add these rivers and lakes to its list of impaired waters which can be used to set limits in discharge permits for industrial activities such as mining. Minnesota Power’s taconite customers could be adversely impacted if they are required to significantly reduce sulfate discharges. Paper, Pulp and Secondary Wood Products. The North American paper and pulp industry faces declining demand due to the impact of electronic substitution for print and changing customer needs. As a result, certain paper and pulp customers have reduced their existing operations in recent years and have pursued or are pursuing product changes in response to the declining demand. We expect operating levels in 2022 at the major paper and pulp mills we serve to be lower than in 2021 as several customers operated at higher than normal levels in 2021. Verso Corporation and ST Paper. In June 2020, Verso Corporation indefinitely idled its paper mill in Duluth, Minnesota (Duluth Mill). Verso Corporation stated the decision was due to the accelerated decline in graphic paper demand resulting from the COVID-19 pandemic and has disclosed it is considering options for the Duluth Mill, including marketing for a sale. On January 29, 2021, Verso Corporation provided notice of termination for its contract. Minnesota Power and Verso Corporation mutually agreed to resolve the outstanding commitments under the contract in January 2022. In May 2021, Verso Corporation announced the completion of the sale of the Duluth Mill to ST Paper LLC (ST Paper). ST Paper has stated it plans to convert the Duluth Mill to produce tissue. In January 2022, Minnesota Power entered into an electric service agreement with ST Paper, subject to MPUC approval, that would begin Large Power customer service with a minimum term of 6-years upon start-up of operations, which is anticipated in 2023. The agreement will qualify as a Large Power customer contract as we expect to serve requirements of at least 10 MW of customer load. Pipeline and Other Industries. Cenovus Energy. In 2018, a fire at Cenovus Energy’s refinery in Superior, Wisconsin, which was owned by Husky Energy at that time, disrupted operations at the facility. Under normal operating conditions, SWL&P provides approximately 14 MW of average monthly demand to the refinery in addition to water service. The facility remains at minimal operations, and the refinery is not expected to resume normal operations until 2023. ALLETE, Inc. 2021 Form 10-K 45 Outlook (Continued) Industrial Customers and Prospective Additional Load (Continued) Prospective Additional Load. Minnesota Power is pursuing new wholesale and retail loads in and around its service territory. Currently, several companies in northeastern Minnesota continue to progress in the development of natural resource-based projects that represent long-term growth potential and load diversity for Minnesota Power. We cannot predict the outcome of these projects. PolyMet. PolyMet is planning to start a new copper-nickel and precious metal (non-ferrous) mining operation in northeastern Minnesota. In 2015, PolyMet announced the completion of the final EIS by state and federal agencies, which was subsequently published in the Federal Register and Minnesota Environmental Quality Board Monitor. The Minnesota Department of Natural Resources (DNR) and the U.S. Army Corps of Engineers have both issued final Records of Decision, finding the final EIS adequate. PolyMet was issued all necessary permits to construct and operate its new mining operation; however, of the more than 20 permits issued to build and operate the mine, three permits remain on hold pending legal or regulatory action, which is expected to continue during 2022. Minnesota Power could supply between 45 MW and 50 MW of load under a 10-year power supply contract with PolyMet that would begin upon start-up of operations. EnergyForward. Minnesota Power is executing EnergyForward, its strategy assuring reliability, protecting affordability and further improving environmental performance. The plan includes completed and planned investments in wind, solar, natural gas and hydroelectric power, construction of additional transmission capacity, the installation of emissions control technology and the idling and retirement of certain coal-fired generating facilities. Minnesota Power has a vision to deliver 100 percent carbon-free energy to customers by 2050, continuing its commitment to climate, customers and communities through its EnergyForward strategy. This vision builds on Minnesota Power’s recent achievement of now providing 50 percent renewable energy to its customers. 2021 Integrated Resource Plan. On February 1, 2021, Minnesota Power filed its latest IRP with the MPUC, which outlines its clean-energy transition plans through 2035. These plans include expanding its renewable energy supply to 70 percent by 2030, achieving coal-free operations at its facilities by 2035, and investing in a resilient and flexible transmission and distribution grid. Minnesota Power has also set a target to achieve an 80 percent reduction in carbon emissions by 2035 compared to 2005 levels. As part of these plans, Minnesota Power anticipates adding approximately 400 MW of new wind and solar energy resources, retiring Boswell Unit 3 by 2030 and transforming Boswell Unit 4 to be coal-free by 2035. Minnesota Power’s plans recognize that advances in technology will play a significant role in completing its transition to carbon-free energy supply, reliably and affordably. A final decision on the IRP is expected in the second half of 2022. In recent years, Minnesota Power has transformed its energy supply from more than a 95 percent reliance on coal to become a leader in the nation’s clean- energy transformation. Since 2013, the company has closed or converted seven of its nine coal-fired units and added nearly 900 megawatts of renewable energy sources. Additionally, Minnesota Power has been a leader in energy conservation, surpassing the state’s conservation goals each year for the past decade. Nemadji Trail Energy Center. In 2017, Minnesota Power submitted a resource package to the MPUC which included requesting approval of a natural gas capacity dedication and other affiliated-interest agreements for NTEC, an approximately 600 MW proposed combined-cycle natural gas-fired generating facility to be built in Superior, Wisconsin, which will be jointly owned by Dairyland Power Cooperative, Basin and South Shore Energy, ALLETE’s non- rate regulated, Wisconsin subsidiary. Minnesota Power is expected to purchase approximately 20 percent of the facility's output starting in 2025 pursuant to the capacity dedication agreement. Renewable Energy. Minnesota Power continues to execute its renewable energy strategy and recently reached its goal of supplying 50 percent of its energy by renewable energy sources. Minnesota Power also has a goal of delivering 100 percent carbon-free energy by 2050. (See EnergyForward.) Minnesota Power has approved cost recovery riders for certain renewable investments and expenditures as well as investments and expenditures related to compliance with the Minnesota Solar Energy Standard. The cost recovery riders allow Minnesota Power to charge retail customers on a current basis for the costs of certain renewable and solar investments and expenditures plus a return on the capital invested. (See Note 4. Regulatory Matters.) ALLETE, Inc. 2021 Form 10-K 46 Outlook (Continued) EnergyForward (Continued) Wind Energy. Minnesota Power’s wind energy facilities consist of Bison (497 MW) located in North Dakota, and Taconite Ridge (25 MW) located in northeastern Minnesota. Minnesota Power also has two long-term wind energy PPAs with an affiliate of NextEra Energy, Inc. to purchase the output from Oliver Wind I (50 MW) and Oliver Wind II (48 MW) located in North Dakota. Minnesota Power uses the 465-mile, 250-kV DC transmission line that runs from Center, North Dakota, to Duluth, Minnesota, to transport wind energy from North Dakota while gradually phasing out coal-based electricity delivered to its system over this transmission line from Square Butte’s lignite coal- fired generating unit. Minnesota Power is currently pursuing a modernization and capacity upgrade of its DC transmission system to continue providing reliable operations and additional system capabilities. Nobles 2 PPA. Minnesota Power has a long-term PPA with Nobles 2 that provides for Minnesota Power to purchase the energy and associated capacity from a 250 MW wind energy facility in southwestern Minnesota through 2040. The agreement provides for the purchase of output from the facility at fixed energy prices. There are no fixed capacity charges, and Minnesota Power will only pay for energy as it is delivered. (See Corporate and Other – Investment in Nobles 2.) Manitoba Hydro. Minnesota Power has three long-term PPAs with Manitoba Hydro. Under the first PPA, Minnesota Power is purchasing surplus energy through April 2022. This energy-only agreement primarily consists of surplus hydro energy on Manitoba Hydro’s system that is delivered to Minnesota Power on a non-firm basis. Under this agreement, Minnesota Power will purchase at least one million MWh of energy over the contract term. The second PPA provides for Minnesota Power to purchase 250 MW of capacity and energy from Manitoba Hydro through May 2035. The third PPA provides for Minnesota Power to purchase up to 133 MW of energy from Manitoba Hydro through June 2040. (See Note 8. Commitments, Guarantees and Contingencies.) Solar Energy. Minnesota Power’s solar energy supply consists of Camp Ripley, a 10 MW solar energy facility at the Camp Ripley Minnesota Army National Guard base and training facility near Little Falls, Minnesota, and a community solar garden in northeastern Minnesota, which is comprised of a 1 MW solar array owned and operated by a third party with the output purchased by Minnesota Power and a 40 kW solar array that is owned and operated by Minnesota Power. SWL&P also plans to construct a 470 kW solar array in 2022 as part of a community solar garden in Superior, Wisconsin, which was approved by the PSCW in October 2020. In June 2020, Minnesota Power filed a proposal with the MPUC to accelerate its plans for purchasing solar energy from approximately 20 MW of solar energy projects in Minnesota which was approved in a June 2021 order. These solar energy projects will be constructed and owned through an ALLETE subsidiary with an estimated investment of $40 million. Construction of these solar energy projects is expected to commence in 2022. Transmission. We continue to make investments in transmission opportunities that strengthen or enhance the transmission grid or take advantage of our geographical location between sources of renewable energy and end users. These include the GNTL, investments to enhance our own transmission facilities, investments in other transmission assets (individually or in combination with others) and our investment in ATC. See Item 1. Business – Regulated Operations and Note 8. Commitments, Guarantees and Contingencies. Duluth Loop Reliability Project. On October 21, 2021, Minnesota Power submitted an application for a certificate of need for the Duluth Loop Reliability Project. This transmission project was proposed to enhance reliability in and around Duluth, Minnesota. The project includes the construction of a new 115- kV transmission line; construction of an approximately one-mile extension of an existing 230-kV transmission line; and upgrades to several substations. The Duluth Loop Reliability Project is expected to be completed and in service by 2025, subject to MPUC approval, with an estimated cost of $50 million to $70 million. ALLETE Clean Energy. ALLETE Clean Energy will pursue growth through acquisitions or project development. ALLETE Clean Energy is targeting acquisitions of existing operating portfolios which have a mix of long-term PSAs in place and/or available for repowering and recontracting. Further, ALLETE Clean Energy will evaluate actions that will lead to the addition of complimentary clean energy products and services. At this time, ALLETE Clean Energy expects acquisitions or development of new facilities will be primarily wind, solar, energy storage or storage ready facilities across North America. ALLETE Clean Energy is also targeting the development of new facilities up to 300 MW each, which will have long-term PSAs in place for the output or may be sold upon completion. ALLETE, Inc. 2021 Form 10-K 47 Outlook (Continued) ALLETE Clean Energy (Continued) Portions of our ALLETE Clean Energy business are experiencing return pressures that are impacting our earnings per share growth from increased competition, and lower forward price curves, as a growing amount of investment capital is being directed into wind generation opportunities. In addition, current and potential new project developments can be negatively affected by a lower ALLETE stock price, which may result in such projects not being accretive, or otherwise unable to satisfy our financial objectives criteria to proceed. In response to these market pressures, we are actively evaluating additional growth opportunities to deliver more comprehensive clean energy solutions for customers at ALLETE Clean Energy, which may include solar, storage solutions, and related energy infrastructure investments and services. We believe that the renewable energy industry is entering a new phase of growth and that we are well-positioned to serve customers and drive future growth at ALLETE. ALLETE Clean Energy will continue to optimize its existing wind energy facility portfolio, seek development of its remaining safe harbor inventory of tax credit qualified turbines, and explore other renewable energy opportunities to expand its service offerings to further enhance its growth and profitability. Federal production tax credit qualification is important to the economics of project development, and ALLETE Clean Energy has invested in equipment to meet production tax credit safe harbor provisions which provides an opportunity to seek development of its remaining safe harbor production tax credit qualified equipment through 2025 based on the most recent PTC safe harbor extension by the IRS. ALLETE Clean Energy has completed its investment of approximately $80 million for production tax credit requalification of approximately 470 WTGs at its Storm Lake I, Storm Lake II, Lake Benton and Condon wind energy facilities. We anticipate annual production tax credits relating to these projects of approximately $17 million to $22 million annually through 2027 and decreasing thereafter through 2030. Disruptions in our supply chains or a lack of available financing resulting from the ongoing COVID- 19 pandemic, if they occur, could jeopardize our ability to complete certain capital projects in time to qualify them for production tax credits. To date we have not experienced disruptions in our supply chains related to the COVID-19 pandemic. In March 2020, ALLETE Clean Energy acquired the rights to the approximately 300 MW Caddo wind development project in Oklahoma from Apex Clean Energy. The Caddo wind project is fully contracted to sell wind power under long-term power sales agreements; construction was completed and tax equity funding of $62.0 million of cash, net of issuance costs, was received in the fourth quarter of 2021 with an additional $183.0 million of cash, net of issuance costs, received in January 2022. Also in January 2022, ALLETE Clean Energy acquired a portion of the non-controlling interest for its Caddo wind energy facility for approximately $30 million. On February 4, 2021, ALLETE Clean Energy entered into a purchase and sale agreement with a subsidiary of Xcel Energy Inc. to sell a 100 MW wind energy facility for approximately $185 million. ALLETE Clean Energy will repower its Northern Wind project, consisting of its 98 MW Chanarambie and Viking wind energy facilities located in southwest Minnesota, as part of the transaction. Construction is expected to begin in 2022 with the Northern Wind project expected to continue operating until the second quarter of 2022. At a hearing in June 2021, the MPUC approved the sale, which is expected to close in late 2022, subject to completion of construction and receipt of permits. ALLETE Clean Energy has experienced inflationary increases and significant cost pressures related to this project and as a result now anticipates a loss on sale of the project, which resulted in an approximately $2 million after-tax charge in the fourth quarter of 2021. In May 2021, ALLETE Clean Energy announced that it acquired the rights to the approximately 92 MW Red Barn wind development project and the approximately 68 MW Whitetail renewable development project in southwestern Wisconsin. ALLETE Clean Energy also signed an asset sale agreement for the completed Red Barn wind project with Wisconsin Public Service Corporation and Madison Gas and Electric Company. At a hearing in January 2022, the PSCW approved the sale of the Red Barn wind project, which is expected to close in 2023, subject to completion of construction and receipt of permits. ALLETE, Inc. 2021 Form 10-K 48 Outlook (Continued) ALLETE Clean Energy (Continued) ALLETE Clean Energy manages risk by having a diverse portfolio of assets, which includes PSA expiration, technology and geographic diversity. The current operating portfolio is subject to typical variations in seasonal wind with higher wind resources typically available in the winter months. The majority of its planned maintenance leverages this seasonality and is performed during lower wind periods. ALLETE Clean Energy’s current operating portfolio is as follows: Region East Midwest South West Wind Energy Facility Armenia Mountain Chanarambie/Viking PSA 1 (a) PSA 2 Lake Benton Storm Lake I Storm Lake II PSA 1 PSA 2 Other Caddo PSA 1 PSA 2 PSA 3 Diamond Spring PSA 1 PSA 2 PSA 3 Condon Glen Ullin South Peak Capacity MW 101 98 PSA MW 100% PSA Expiration 2024 104 108 77 17 303 303 50 106 80 12% 88% 100% 100% 90% 10% 100% 26% 66% 7% 58% 25% 16% 100% 100% 100% 2023 2023 2028 2027 2022 2032 2028 2034 2034 2034 2035 2032 2035 2022 2039 2035 (a) The PSA expiration assumes the exercise of four one-year renewal options that ALLETE Clean Energy has the sole right to exercise. Non-cash amortization to revenue recognized by ALLETE Clean Energy relates to the amortization of differences between contract prices and estimated market prices on assumed PSAs. As part of wind energy facility acquisitions, ALLETE Clean Energy assumed various PSAs that were above or below estimated market prices at the time of acquisition; the resulting differences between contract prices and estimated market prices are amortized to revenue over the remaining PSA term. Non-cash amortization is expected to be approximately $7 million in 2022, $5 million in 2023, $6 million annually in 2024 through 2027, and decreasing thereafter through 2032. Corporate and Other. BNI Energy. In 2021, BNI Energy sold 3.9 million tons of coal (4.2 million tons in 2020) and anticipates 2022 sales will be similar to 2021. BNI Energy operates under cost-plus fixed fee agreements extending through December 31, 2037. Investment in Nobles 2. Our subsidiary, ALLETE South Wind, owns a 49 percent equity interest in Nobles 2, the entity that owns and operates a 250 MW wind energy facility in southwestern Minnesota pursuant to a 20-year PPA with Minnesota Power. We account for our investment in Nobles 2 under the equity method of accounting. (See Note 5. Equity Investments.) ALLETE, Inc. 2021 Form 10-K 49 Outlook (Continued) Corporate and Other (Continued) South Shore Energy. South Shore Energy, ALLETE’s non-rate regulated, Wisconsin subsidiary, is developing NTEC, an approximately 600 MW proposed combined-cycle natural gas-fired generating facility to be built in Superior, Wisconsin, which will be jointly owned by Dairyland Power Cooperative, Basin and South Shore Energy. Minnesota Power is expected to purchase approximately 20 percent of the facility's output starting in 2025 pursuant to a capacity dedication agreement. Construction of NTEC is subject to obtaining additional permits from local, state and federal authorities. The total project cost is estimated to be approximately $700 million, of which South Shore Energy’s portion is expected to be approximately $150 million. South Shore Energy’s portion of NTEC project costs incurred through December 31, 2021, is approximately $5 million. On October 1, 2021, South Shore Energy sold a portion of its undivided ownership interest in NTEC for approximately $20 million representing reimbursement of current costs plus a fee for prior development costs and risks incurred. Following the transaction, South Shore Energy now owns a 20 percent undivided ownership interest in NTEC, Basin owns a 30 percent undivided ownership interest in NTEC and Dairyland Power Cooperative continues to own a 50 percent undivided ownership interest in NTEC. The closing of the transaction resulted in the recognition of an approximately $8.5 million after-tax gain recorded in Corporate and Other in the fourth quarter of 2021, related to prior development costs and risks incurred. ALLETE Properties. Our strategy incorporates the possibility of a bulk sale of the entire ALLETE Properties portfolio. Proceeds from a bulk sale would be strategically deployed to support growth initiatives at our Regulated Operations and ALLETE Clean Energy. ALLETE Properties also continues to pursue sales of individual parcels over time and will continue to maintain key entitlements and infrastructure. Income Taxes ALLETE’s aggregate federal and multi-state statutory tax rate is approximately 28 percent for 2021. ALLETE also has tax credits and other tax adjustments that reduce the combined statutory rate to the effective tax rate. These tax credits and adjustments historically have included items such as production tax credits, excess deferred taxes, non-controlling interests in subsidiaries, as well as other items. The annual effective rate can also be impacted by such items as changes in income before income taxes, state and federal tax law changes that become effective during the year, business combinations, tax planning initiatives and resolution of prior years’ tax matters. We expect our effective tax rate to be a benefit of approximately 5 percent for 2022 primarily due to federal production tax credits as a result of wind energy generation and non-controlling interests in subsidiaries. We also expect that our effective tax rate will be lower than the combined statutory rate over the next 10 years due to production tax credits attributable to our wind energy generation. ALLETE, Inc. 2021 Form 10-K 50 Liquidity and Capital Resources Liquidity Position. ALLETE is well-positioned to meet its liquidity needs; however, the Company is monitoring capital markets and other financing sources in light of the ongoing COVID-19 pandemic. (See Item 1A. Risk Factors.) A disruption in capital markets could lead to increased borrowing costs or adversely impact our ability to access capital markets or other financing sources. If we are not able to access capital on acceptable terms in sufficient amounts and when needed, or at all, the ability to maintain our businesses or to implement our business plans would be adversely affected. As of December 31, 2021, we had cash and cash equivalents of $45.1 million, $240.8 million in available consolidated lines of credit, 2.1 million original issue shares of common stock available for issuance through a distribution agreement with Lampert Capital Markets and a debt-to-capital ratio of 40 percent. Capital Structure. ALLETE’s capital structure for each of the last three years is as follows: As of December 31 Millions ALLETE Equity Non-Controlling Interest in Subsidiaries Short-Term and Long-Term Debt (a) % 2021 $2,413.1 533.2 1,986.4 $4,932.7 49 11 40 100 2020 % 2019 % $2,294.6 505.6 1,806.4 $4,606.6 50 11 39 100 $2,231.9 — 1,622.6 $3,958.2 56 3 41 100 (a) Excludes unamortized debt issuance costs. Cash Flows. Selected information from ALLETE’s Consolidated Statement of Cash Flows is as follows: Year Ended December 31 Millions Cash, Cash Equivalents and Restricted Cash at Beginning of Period Cash Flows from (used for) Operating Activities Investing Activities Financing Activities Change in Cash, Cash Equivalents and Restricted Cash Cash, Cash Equivalents and Restricted Cash at End of Period 2021 $65.2 263.5 (485.2) 204.2 (17.5) $47.7 2020 $92.5 299.8 (812.8) 485.7 (27.3) $65.2 2019 $79.0 246.9 (342.7) 109.3 13.5 $92.5 Operating Activities. Cash from operating activities was lower in 2021 compared to 2020. Cash from operating activities in 2021 included lower net income and higher payments for inventories compared to 2020, and was negatively impacted by the timing of recovery and refund of the fuel adjustment clause. Cash from operating activities was higher in 2020 compared to 2019. Cash from operating activities in 2019 included the refund of Minnesota Power’s provisions for interim rates and tax reform, and the impact of U.S. Water Services prior to its sale. Cash from operating activities in 2020 included lower collections of accounts receivable due to timing. Investing Activities. Cash used for investing activities was lower in 2021 compared to 2020. Cash used for investing activities in 2021 reflected lower additions to property, plant and equipment and lower payments for equity method investments compared to 2020. Cash used for investing activities in 2020 was higher compared to 2019. Cash used for investing activities in 2020 included higher additions to property, plant and equipment and additional payments for equity method investments compared to 2019. Cash used for investing activities in 2019 included proceeds received from the sale of U.S. Water Services. Financing Activities. Cash from financing activities was lower in 2021 compared to 2020 primarily due to lower proceeds from non-controlling interest in subsidiaries and higher repayments of short-term and long-term debt in 2021. These decreases were partially offset by higher proceeds from the issuance of common stock and higher proceeds from the issuance of short-term and long-term debt in 2021. ALLETE, Inc. 2021 Form 10-K 51 Liquidity and Capital Resources (Continued) Cash Flows (Continued) Cash from financing activities was higher in 2020 compared to 2019 primarily due to higher proceeds from the issuance of long-term debt and proceeds from a tax equity financing (non-controlling interest in subsidiaries) in 2020. These increases were partially offset by higher repayments of long-term debt in 2020. Working Capital. Additional working capital, if and when needed, generally is provided by consolidated bank lines of credit and the issuance of securities, including long-term debt, common stock and commercial paper. As of December 31, 2021, we had consolidated bank lines of credit aggregating $432.0 million ($407.0 million as of December 31, 2020), most of which expire in January 2025. We had $31.5 million outstanding in standby letters of credit and $159.7 million outstanding draws under our lines of credit as of December 31, 2021 ($22.3 million in standby letters of credit and no outstanding draws as of December 31, 2020). We also have other credit facility agreements in place that provide the ability to issue up to $100.0 million in standby letters of credit. As of December 31, 2021, we had $91.2 million outstanding in standby letters of credit under these agreements. In January 2022, ALLETE Clean Energy received approximately $183.0 million from final closing of tax equity funding for the Caddo wind energy facility. The proceeds from the funding were used to pay down a portion of outstanding draws on our lines of credit. In addition, as of December 31, 2021, we had 3.1 million original issue shares of our common stock available for issuance through Invest Direct and 2.1 million original issue shares of common stock available for issuance through a distribution agreement with Lampert Capital Markets. (See Securities.) The amount and timing of future sales of our securities will depend upon market conditions and our specific needs. Securities. We entered into a distribution agreement with Lampert Capital Markets, in 2008, as amended most recently in 2020, with respect to the issuance and sale of up to an aggregate of 13.6 million shares of our common stock, without par value, of which 2.1 million shares remain available for issuance as of December 31, 2021. For the year ended December 31, 2021, 0.8 million shares of common stock were issued under this agreement resulting in net proceeds of $51.0 million (none in 2020 and 2019). During the year ended December 31, 2021, we issued 0.3 million shares of common stock through Invest Direct, the Employee Stock Purchase Plan and the Retirement Savings and Stock Ownership Plan, resulting in net proceeds of $18.9 million (0.4 million shares for net proceeds of $18.1 million in 2020; 0.2 million shares for net proceeds of $1.9 million in 2019). See Note 9. Common Stock and Earnings Per Share for additional detail regarding ALLETE’s equity securities. Financial Covenants. See Note 7. Short-Term and Long-Term Debt for information regarding our financial covenants. Pension and Other Postretirement Benefit Plans. Management considers various factors when making funding decisions, such as regulatory requirements, actuarially determined minimum contribution requirements and contributions required to avoid benefit restrictions for the defined benefit pension plans. For the year ended December 31, 2021, we contributed $10.3 million in cash to the defined benefit pension plans. We do not expect to make any contributions to our defined benefit pension plans in 2022, and we do not expect to make any contributions to our other postretirement benefit plans in 2022. (See Note 9. Common Stock and Earnings Per Share and Note 11. Pension and Other Postretirement Benefit Plans.) Off-Balance Sheet Arrangements. Off-balance sheet arrangements are discussed in Note 8. Commitments, Guarantees and Contingencies. ALLETE, Inc. 2021 Form 10-K 52 Liquidity and Capital Resources (Continued) Contractual Obligations and Commercial Commitments. ALLETE has contractual obligations and other commitments that will need to be funded in the future, in addition to its capital expenditure programs. Material contractual obligations and other commitments are as follows: Long-Term Debt. ALLETE has material long-term debt obligations, including long-term debt due within one year. These obligations include the principal amount of bonds, notes and loans which are recorded on the Consolidated Balance Sheet, plus interest. (See Note 7. Short-Term and Long‑Term Debt.) Pension and Other Postretirement Benefit Plans. Pension and other postretirement benefit plan obligations include the current estimate of future benefit payments. Pension contributions are dependent on several factors including realized asset performance, future discount rate and other actuarial assumptions, Internal Revenue Service and other regulatory requirements, and contributions required to avoid benefit restrictions for the pension plans. Funding for the other postretirement benefit plans is impacted by realized asset performance, future discount rate and other actuarial assumptions, and utility regulatory requirements. Our obligations are estimates and will change based on actual market performance, changes in interest rates and any changes in governmental regulations. (See Note 11. Pension and Other Postretirement Benefit Plans.) Operating Lease Obligations. ALLETE has certain operating lease obligations for the minimum payments required under various lease agreements which are recorded on the Consolidated Balance Sheet. (See Note 1. Operations and Significant Accounting Policies.) Easement Obligations. ALLETE has easement obligations for the minimum payments required under our land easement agreements at our wind energy facilities. (See Note 8. Commitments, Guarantees and Contingencies.) PPA Obligations. PPA obligations represent our Square Butte, Manitoba Hydro and other PPAs. (See Note 8. Commitments, Guarantees and Contingencies.) Other Purchase Obligations. ALLETE has other purchase obligations covering our minimum purchase commitments under coal supply and rail contracts, and long-term service agreements for wind energy facilities. (See Note 8. Commitments, Guarantees and Contingencies.) Credit Ratings. Access to reasonably priced capital markets is dependent in part on credit and ratings. Our securities have been rated by S&P and by Moody’s. Rating agencies use both quantitative and qualitative measures in determining a company’s credit rating. These measures include business risk, liquidity risk, competitive position, capital mix, financial condition, predictability of cash flows, management strength and future direction. Some of the quantitative measures can be analyzed through a few key financial ratios, while the qualitative ones are more subjective. Our current credit ratings are listed in the following table: Credit Ratings Issuer Credit Rating Commercial Paper First Mortgage Bonds (a) Not rated by S&P. S&P BBB A-2 (a) Moody’s Baa1 P-2 A2 The disclosure of these credit ratings is not a recommendation to buy, sell or hold our securities. Ratings are subject to revision or withdrawal at any time by the assigning rating organization. Each rating should be evaluated independently of any other rating. Common Stock Dividends. ALLETE is committed to providing a competitive dividend to its shareholders while at the same time funding its growth. ALLETE’s long-term objective is to maintain a dividend payout ratio similar to our peers and provide for future dividend increases. Our targeted payout range is between 60 percent and 70 percent. In 2021, we paid out 78 percent (74 percent in 2020; 65 percent in 2019) of our per share earnings in dividends. On February 3, 2022, our Board of Directors declared a dividend of $0.65 per share, which is payable on March 1, 2022, to shareholders of record at the close of business on February 15, 2022. ALLETE, Inc. 2021 Form 10-K 53 Capital Requirements ALLETE’s projected capital expenditures for the years 2022 through 2026 are presented in the following table. Actual capital expenditures may vary from the projections due to changes in forecasted plant maintenance, regulatory decisions or approvals, future environmental requirements, base load growth, capital market conditions or executions of new business strategies. Projected capital expenditures exclude amounts for projects that will be sold to third parties upon completion.

(See Outlook – ALLETE Clean Energy.) (b) Our portion of estimated capital expenditures for construction of NTEC, an approximately 600 MW proposed combined-cycle natural gas-fired generating facility to be built in Superior, Wisconsin, which will be jointly owned by Dairyland Power Cooperative, Basin and South Shore Energy. We are well positioned to meet our financing needs due to adequate operating cash flows, available additional working capital and access to capital markets. We will finance capital expenditures from a combination of internally generated funds, debt and equity issuance proceeds. We intend to maintain a capital structure with capital ratios near current levels. (See Capital Structure.) Environmental and Other Matters Our businesses are subject to regulation of environmental matters by various federal, state and local authorities. A number of regulatory changes to the Clean Air Act, the Clean Water Act and various waste management requirements have been promulgated by both the EPA and state authorities over the past several years. Minnesota Power’s facilities are subject to additional requirements under many of these regulations. Minnesota Power is reshaping its generation portfolio, over time, to reduce its reliance on coal, has installed cost-effective emission control technology, and advocates for sound science and policy during rulemaking implementation. (See Note 8. Commitments, Guarantees and Contingencies.) ALLETE, Inc. 2021 Form 10-K 54 Market Risk Securities Investments. Available-for-Sale Securities. As of December 31, 2021, our available-for-sale securities portfolio consisted primarily of securities held in other postretirement plans to fund employee benefits. INTEREST RATE RISK We are exposed to risks resulting from changes in interest rates as a result of our issuance of variable rate debt. We manage our interest rate risk by varying the issuance and maturity dates of our fixed rate debt, limiting the amount of variable rate debt, and continually monitoring the effects of market changes in interest rates. We may also enter into derivative financial instruments, such as interest rate swaps, to mitigate interest rate exposure. The following table presents the long-term debt obligations and the corresponding weighted average interest rate as of December 31, 2021: Interest Rate Sensitive Financial Instruments Long-Term Debt Fixed Rate – Millions Average Interest Rate – % Variable Rate – Millions Average Interest Rate – % Expected Maturity Date 2022 2023 2024 2025 2026 Thereafter Total Fair Value $89.8 3.7 $124.7 1.0 $89.7 5.8 $74.4 3.9 — — — — $213.9 3.4 $172.8 2.8 $77.2 3.3 — — $1,143.9 4.1 $1,688.9 4.0 $1,895.1 — — $297.5 2.0 $297.5 Interest rates on variable rate long-term debt are reset on a periodic basis reflecting prevailing market conditions. Based on the variable rate debt outstanding as of December 31, 2021, an increase of 100 basis points in interest rates would impact the amount of pre-tax interest expense by $3.0 million. This amount was determined by considering the impact of a hypothetical 100 basis point increase to the average variable interest rate on the variable rate debt outstanding as of December 31, 2021. COMMODITY PRICE RISK Our regulated utility operations incur costs for power and fuel (primarily coal and related transportation) in Minnesota, and power and natural gas purchased for resale in our regulated service territory in Wisconsin. Minnesota Power’s exposure to price risk for these commodities is significantly mitigated by the current ratemaking process and regulatory framework, which allows recovery of fuel costs in excess of those included in base rates or distribution of savings in fuel costs to ratepayers. SWL&P’s exposure to price risk for natural gas is significantly mitigated by the current ratemaking process and regulatory framework, which allows the commodity cost to be passed through to customers. We seek to prudently manage our customers’ exposure to price risk by entering into contracts of various durations and terms for the purchase of power and coal and related transportation costs (Minnesota Power) and natural gas (SWL&P). POWER MARKETING Minnesota Power’s power marketing activities consist of: (1) purchasing energy in the wholesale market to serve its regulated service territory when energy requirements exceed generation output; and (2) selling excess available energy and purchased power. From time to time, Minnesota Power may have excess energy that is temporarily not required by retail and municipal customers in our regulated service territory. Minnesota Power actively sells any excess energy to the wholesale market to optimize the value of its generating facilities. We are exposed to credit risk primarily through our power marketing activities. We use credit policies to manage credit risk, which includes utilizing an established credit approval process and monitoring counterparty limits. Recently Adopted Accounting Pronouncements.

Opinions on the Financial Statements and Internal Control over Financial Reporting Report of Independent Registered Public Accounting Firm We have audited the accompanying consolidated balance sheets of ALLETE, Inc. and its subsidiaries (the “Company”) as of December 31, 2021 and December 31, 2020, and the related consolidated statements of income, of comprehensive income, of equity and of cash flows for each of the three years in the period ended December 31, 2021, including the related notes and financial statement schedule listed in the index appearing under Item 15(a)(2) (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2021 and December 31, 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO. Basis for Opinions The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control Over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions. Definition and Limitations of Internal Control over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. ALLETE, Inc. 2021 Form 10-K 66 Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Critical Audit Matters The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates. Accounting for the Effects of Regulatory Matters As described in Note 4 to the consolidated financial statements, the Company’s regulated utility operations are subject to accounting standards for the effects of certain types of regulation. As of December 31, 2021, there was $512 million of regulatory assets and $545 million of regulatory liabilities recorded. Regulatory assets represent incurred costs that have been deferred as they are probable for recovery in customer rates. Regulatory liabilities represent obligations to make refunds to customers and amounts collected in rates for which the related costs have not yet been incurred. Management assesses quarterly whether regulatory assets and liabilities meet the criteria for probability of future recovery or deferral. As disclosed by management, these standards require the Company to reflect the effect of regulatory decisions in its financial statements. This assessment considers factors such as, but not limited to, changes in the regulatory environment and recent rate orders to other regulated entities under the same jurisdiction. If future recovery or refund of costs becomes no longer probable, the assets and liabilities would be recognized in current period net income or other comprehensive income. The principal consideration for our determination that performing procedures relating to the Company’s accounting for the effects of regulatory matters is a critical audit matter is the significant judgment by management in determining the recoverability of costs; this in turn led to a high degree of auditor judgment, subjectivity and effort in performing procedures and evaluating audit evidence obtained related to the recoverability of costs. Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to management’s implementation of new regulatory orders, changes to existing regulatory orders, and assessing the recoverability of costs. These procedures also included, among others, evaluating (i) the reasonableness of management’s assessment of impacts arising from correspondence with regulators and changes in laws and regulations, (ii) management’s judgments related to the recoverability of regulatory assets and the establishment of regulatory liabilities, and (iii) the sufficiency of the disclosures in the consolidated financial statements. Testing the regulatory assets and liabilities involved considering the provisions and formulas outlined in rate orders, other regulatory correspondence, and application of relevant regulatory precedents. /s/ PricewaterhouseCoopers LLP Minneapolis, Minnesota February 16, 2022 We have served as the Company’s auditor since 1963.

References in this report to “we,” “us,” and “our” are to ALLETE and its subsidiaries, collectively. We prepare our financial statements in conformity with GAAP. These principles require management to make informed judgments, best estimates, and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses. Actual results could differ from those estimates. Subsequent Events. The Company performed an evaluation of subsequent events for potential recognition and disclosure through the time of the financial statements issuance. Principles of Consolidation. Our Consolidated Financial Statements include the accounts of ALLETE, all of our majority‑owned subsidiary companies and variable interest entities of which ALLETE is the primary beneficiary. All material intercompany balances and transactions have been eliminated in consolidation. Variable Interest Entities. The accounting guidance for “Variable Interest Entities” (VIE) is a consolidation model that considers if a company has a variable interest in a VIE. A VIE is a legal entity that possesses any of the following conditions: the entity’s equity at risk is not sufficient to permit the legal entity to finance its activities without additional subordinated financial support, equity owners are unable to direct the activities that most significantly impact the legal entity’s economic performance (or they possess disproportionate voting rights in relation to the economic interest in the legal entity), or the equity owners lack the obligation to absorb the legal entity’s expected losses or the right to receive the legal entity’s expected residual returns. Entities are required to consolidate a VIE when it is determined that they have a controlling financial interest in a VIE and therefore, are the primary beneficiary of that VIE, as defined by the accounting guidance for “Variable Interest Entities.” In determining whether ALLETE is the primary beneficiary of a VIE, management considers whether ALLETE has the power to direct the most significant activities of the VIE and is obligated to absorb losses or receive the expected residual returns that are significant to the VIE. The accounting guidance for VIEs applies to certain ALLETE Clean Energy wind energy facilities and our investment in Nobles 2. (See Tax Equity Financing.) Business Segments. We present three reportable segments: Regulated Operations, ALLETE Clean Energy and U.S. Water Services. Our segments were determined in accordance with the guidance on segment reporting. We measure performance of our operations through budgeting and monitoring of contributions to consolidated net income by each business segment. Regulated Operations includes our regulated utilities, Minnesota Power and SWL&P, as well as our investment in ATC, a Wisconsin-based regulated utility that owns and maintains electric transmission assets in portions of Wisconsin, Michigan, Minnesota and Illinois. Minnesota Power provides regulated utility electric service in northeastern Minnesota to approximately 150,000 retail customers. Minnesota Power also has 15 non-affiliated municipal customers in Minnesota. SWL&P is a Wisconsin utility and a wholesale customer of Minnesota Power. SWL&P provides regulated utility electric, natural gas and water service in northwestern Wisconsin to approximately 15,000 electric customers, 13,000 natural gas customers and 10,000 water customers. Our regulated utility operations include retail and wholesale activities under the jurisdiction of state and federal regulatory authorities. ALLETE Clean Energy focuses on developing, acquiring, and operating clean and renewable energy projects. ALLETE Clean Energy currently owns and operates, in seven states, more than 1,300 MW of nameplate capacity wind energy generation that is contracted under PSAs of various durations. In addition, ALLETE Clean Energy currently has approximately 200 MW of wind energy facilities under contract for sale to others. ALLETE Clean Energy also engages in the development of wind energy facilities to operate under long-term PSAs or for sale to others upon completion. U.S. Water Services provided integrated water management for industry by combining chemical, equipment, engineering and service for customized solutions to reduce water and energy usage, and improve efficiency. In March 2019, the Company sold U.S. Water Services to a subsidiary of Kurita Water Industries Ltd. pursuant to a stock purchase agreement for approximately $270 million in cash, net of transaction costs and cash retained. ALLETE, Inc. 2021 Form 10-K 73 NOTE 1. OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (Continued) Corporate and Other is comprised of BNI Energy, our investment in Nobles 2, South Shore Energy, ALLETE Properties, other business development and corporate expenditures, unallocated interest expense, a small amount of non-rate base generation, approximately 4,000 acres of land in Minnesota, and earnings on cash and investments. BNI Energy mines and sells lignite coal to two North Dakota mine-mouth generating units, one of which is Square Butte. In 2021, Square Butte supplied 50 percent (227.5 MW) of its output to Minnesota Power under long-term contracts. (See Note 8. Commitments, Guarantees and Contingencies.) Our investment in Nobles 2 represents a 49 percent equity interest in Nobles 2, the entity that owns and operates a 250 MW wind energy facility in southwestern Minnesota pursuant to a 20-year PPA with Minnesota Power. South Shore Energy, ALLETE’s non-rate regulated, Wisconsin subsidiary, is developing NTEC, an approximately 600 MW proposed combined-cycle natural gas-fired generating facility to be built in Superior, Wisconsin, which will be jointly owned by Dairyland Power Cooperative, Basin and South Shore Energy. Minnesota Power is expected to purchase approximately 20 percent of the facility's output starting in 2025 pursuant to a capacity dedication agreement. Construction of NTEC is subject to obtaining additional permits from local, state and federal authorities. The total project cost is estimated to be approximately $700 million, of which South Shore Energy’s portion is expected to be approximately $150 million. South Shore Energy’s portion of NTEC project costs incurred through December 31, 2021, is approximately $5 million. On October 1, 2021, South Shore Energy sold a portion of its undivided ownership interest in NTEC for approximately $20 million representing reimbursement of current costs plus a fee for prior development costs and risks incurred. Following the transaction, South Shore Energy now owns a 20 percent undivided ownership interest in NTEC, Basin owns a 30 percent undivided ownership interest in NTEC and Dairyland Power Cooperative continues to own a 50 percent undivided ownership interest in NTEC. The closing of the transaction resulted in the recognition of an approximately $8.5 million after-tax gain recorded in Corporate and Other in the fourth quarter of 2021, related to prior development costs and risks incurred. ALLETE Properties represents our legacy Florida real estate investment. Our strategy incorporates the possibility of a bulk sale of the entire ALLETE Properties portfolio. Proceeds from a bulk sale would be strategically deployed to support growth at our Regulated Operations and ALLETE Clean Energy. ALLETE Properties continues to pursue sales of individual parcels over time and will continue to maintain key entitlements and infrastructure. Cash, Cash Equivalents and Restricted Cash. We consider all investments purchased with original maturities of three months or less to be cash equivalents. As of December 31, 2021, and 2020, restricted cash amounts included in Prepayments and Other on the Consolidated Balance Sheet include collateral deposits required under an ALLETE Clean Energy loan agreement. The December 31, 2019 amount also includes deposits required under tax equity financing agreements. The restricted cash amounts included in Other Non-Current Assets represent collateral deposits required under an ALLETE Clean Energy loan agreement and PSAs. The December 31, 2020 and 2019 amounts also include deposits required under tax equity financing agreements. The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the Consolidated Balance Sheet that aggregate to the amounts presented in the Consolidated Statement of Cash Flows.

(b) Amount reclassified to Current Liabilities resulting from the exercise of an option to buy out a non-controlling interest. Accounts Receivable. Accounts receivable are reported on the Consolidated Balance Sheet net of an allowance for doubtful accounts. The allowance is based on our evaluation of the receivable portfolio under current conditions, overall portfolio quality, review of specific situations and such other factors that, in our judgment, deserve recognition in estimating losses. Accounts Receivable As of December 31 Millions Trade Accounts Receivable Billed Unbilled Less: Allowance for Doubtful Accounts Total Accounts Receivable 2021 2020 $100.8 24.7 1.8 $123.7 $93.5 20.9 2.5 $111.9 Concentration of Credit Risk. We are subject to concentration of credit risk primarily as a result of accounts receivable. Minnesota Power sells electricity to eight Large Power Customers. Receivables from these customers totaled $7.8 million as of December 31, 2021 ($10.3 million as of December 31, 2020). Minnesota Power does not obtain collateral to support utility receivables, but monitors the credit standing of major customers. In addition, Minnesota Power, as permitted by the MPUC, requires its taconite-producing Large Power Customers to pay weekly for electric usage based on monthly energy usage estimates, which allows us to closely manage collection of amounts due. Minnesota Power’s taconite customers, which are currently owned by two entities at the end of 2021, accounted for approximately 32 percent of Regulated Operations operating revenue and approximately 28 percent of consolidated operating revenue in 2021 (29 percent of Regulated Operations operating revenue and 25 percent of consolidated operating revenue in 2020). In 2019, a single entity accounted for approximately 14 percent of Regulated Operations operating revenue and 12 percent of consolidated operating revenue. Long-Term Finance Receivables. Long-term finance receivables relating to our real estate operations are collateralized by property sold, accrue interest at market-based rates and are net of an allowance for doubtful accounts. We assess delinquent finance receivables by comparing the balance of such receivables to the estimated fair value of the collateralized property. If the fair value of the property is less than the finance receivable, we record a reserve for the difference. We estimate fair value based on recent property tax assessed values or current appraisals. Available-for-Sale Securities. Available-for-sale debt and equity securities are recorded at fair value. Unrealized gains and losses on available-for-sale debt securities are included in accumulated other comprehensive income (loss), net of tax. Unrealized gains and losses on available-for-sale equity securities are recognized in earnings. We use the specific identification method as the basis for determining the cost of securities sold. Inventories – Net. Inventories are stated at the lower of cost or net realizable value. Inventories in our Regulated Operations segment are carried at an average cost or first-in, first-out basis. Inventories in our ALLETE Clean Energy segment and Corporate and Other businesses are carried at an average cost, first-in, first-out or specific identification basis.

OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (Continued) Inventories – Net As of December 31 Millions Fuel (a) Materials and Supplies Construction of Wind Energy Facilities (b) Total Inventories – Net 2021 $18.7 56.1 22.9 $97.7 2020 $23.1 51.1 — $74.2 (a) Fuel consists primarily of coal inventory at Minnesota Power. (b) Project costs related to ALLETE Clean Energy’s Northern Wind and Red Barn wind projects which are expected be sold in late 2022 and 2023, respectively. (See Other Current Liabilities.) Property, Plant and Equipment. Property, plant and equipment are recorded at original cost and are reported on the Consolidated Balance Sheet net of accumulated depreciation. Expenditures for additions, significant replacements, improvements and major plant overhauls are capitalized; maintenance and repair costs are expensed as incurred. Gains or losses on property, plant and equipment for Corporate and Other operations are recognized when they are retired or otherwise disposed. When property, plant and equipment in our Regulated Operations and ALLETE Clean Energy segments are retired or otherwise disposed, no gain or loss is recognized in accordance with the accounting standards for component depreciation except for certain circumstances where the retirement is unforeseen or unexpected. Our Regulated Operations capitalize AFUDC, which includes both an interest and equity component. AFUDC represents the cost of both debt and equity funds used to finance utility plant additions during construction periods. AFUDC amounts capitalized are included in rate base and are recovered from customers as the related property is depreciated. Upon MPUC approval of cost recovery, the recognition of AFUDC ceases. (See Note 2. Property, Plant and Equipment.) We believe that long-standing ratemaking practices approved by applicable state and federal regulatory commissions allow for the recovery of the remaining book value of retired plant assets. Minnesota Power’s 2015 IRP contained steps in Minnesota Power’s EnergyForward plan including the economic idling of Taconite Harbor Units 1 and 2 in 2016, and the ceasing of coal-fired operations at Taconite Harbor in 2020. As of December 31, 2021, Taconite Harbor had a net book value of approximately $45 million. The MPUC order for the 2015 IRP also directed Minnesota Power to retire Boswell Units 1 and 2, which occurred in the fourth quarter of 2018. As part of the 2016 general retail rate case, the MPUC allowed recovery of the remaining book value of Boswell Units 1 and 2 through 2022. In its latest IRP filing, Minnesota Power proposed retiring Boswell Unit 3 by 2030 and transforming Boswell Unit 4 to be coal-free by 2035. Boswell Unit 3 and Unit 4 have a net book value of approximately $245 million and $435 million, respectively, as of December 31, 2021. (See Note 4. Regulatory Matters.) We do not expect to record any impairment charge as a result of these operating changes at Taconite Harbor and Boswell. In addition, we expect to be able to continue depreciating these assets for at least their established remaining useful lives; however, we are unable to predict the impact of regulatory outcomes resulting in changes to their established remaining useful lives. Impairment of Long-Lived Assets. We review our long-lived assets for indicators of impairment in accordance with the accounting standards for property, plant and equipment on a quarterly basis. This includes our property, plant and equipment (see Property, Plant and Equipment) and land inventory. Land inventory is accounted for as held for use and is recorded at cost, unless the carrying value is determined not to be recoverable in accordance with the accounting standards for property, plant and equipment, in which case the land inventory is written down to estimated fair value. In accordance with the accounting standards for property, plant and equipment, if indicators of impairment exist, we test our long‑lived assets for recoverability by comparing the carrying amount of the asset to the undiscounted future net cash flows expected to be generated by the asset. Cash flows are assessed at the lowest level of identifiable cash flows. The undiscounted future net cash flows are impacted by trends and factors known to us at the time they are calculated and our expectations related to: management’s best estimate of future use; sales prices; holding period and timing of sales; method of disposition; and future expenditures necessary to maintain the operations. We continue to monitor changes in the broader energy markets along with wind resource expectations that could indicate impairment at ALLETE Clean Energy wind energy facilities upon contract expirations. A continued decline in energy prices or lower wind resource expectations could result in a future impairment. In 2021, 2020, and 2019, there were no indicators of impairment for our property, plant, and equipment or land inventory. As a result, no impairment was recorded in 2021, 2020 or 2019. ALLETE, Inc. 2021 Form 10-K 76 NOTE 1. OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (Continued) Derivatives. ALLETE is exposed to certain risks relating to its business operations that can be managed through the use of derivative instruments. ALLETE may enter into derivative instruments to manage those risks including interest rate risk related to certain variable-rate borrowings and commodity price risk related to sales to retail and municipal customers as well as other power suppliers. We have determined that either these agreements are not derivatives, or, if they are derivatives, the agreements qualify for the normal purchases and normal sales exception to derivative accounting guidance; therefore, derivative accounting is not required. Accounting for Stock-Based Compensation. We apply the fair value recognition guidance for share-based payments. Under this guidance, we recognize stock-based compensation expense for all share-based payments granted, net of an estimated forfeiture rate. (See Note 12. Employee Stock and Incentive Plans.)

OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (Continued) Leases. We determine if a contract is, or contains, a lease at inception and recognize a right-of-use asset and lease liability for all leases with a term greater than 12 months. Our right-of-use assets and lease liabilities for operating leases are included in Other Non-Current Assets, Other Current Liabilities and Other Non- Current Liabilities, respectively, in our Consolidated Balance Sheet. We currently do not have any finance leases. Right-of-use assets represent our right to use an underlying asset for the lease term and lease liabilities represent the obligation to make lease payments arising from the lease. Operating lease right-of-use assets and lease liabilities are recognized at the commencement date based on the estimated present value of lease payments over the lease term. As our leases do not provide an explicit rate, we determine the present value of future lease payments based on our estimated incremental borrowing rate using information available at the lease commencement date. The operating lease right-of-use asset includes lease payments to be made during the lease term and any lease incentives, as applicable. Our leases may include options to extend or buy out the lease at certain points throughout the term, and if it is reasonably certain at lease commencement that we will exercise that option, we include those rental payments in our calculation of the right-of-use asset and lease liability. Lease and rent expense is recognized on a straight-line basis over the lease term. Leases with a term of 12 months or less are not recognized on the Consolidated Balance Sheet. The majority of our operating leases are for heavy equipment, vehicles and land with fixed monthly payments which we group into two categories: Vehicles and Equipment; and Land and Other. Our largest operating lease is for the dragline at BNI Energy which includes a termination payment at the end of the lease term if we do not exercise our purchase option. The amount of this payment is $3 million and is included in our calculation of the right-of-use asset and lease liability recorded. None of our other leases contain residual value guarantees.

We review environmental matters on a quarterly basis. Accruals for environmental matters are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated based on current law and existing technologies. Accruals are adjusted as assessment and remediation efforts progress, or as additional technical or legal information becomes available. Accruals for environmental liabilities are included in the Consolidated Balance Sheet at undiscounted amounts and exclude claims for recoveries from insurance or other third parties. Costs related to environmental contamination treatment and cleanup are expensed unless recoverable in rates from customers. (See Note 8. Commitments, Guarantees and Contingencies.) Revenue. Contracts with Customers – Utility includes sales from our regulated operations for generation, transmission and distribution of electric service, and distribution of water and gas services to our customers. Also included is an immaterial amount of regulated steam generation that is used by customers in the production of paper and pulp. Contracts with Customers – Non-utility includes sales of goods and services to customers from ALLETE Clean Energy, U.S. Water Services and our Corporate and Other businesses. Other – Non-utility is the non-cash adjustments to revenue recognized by ALLETE Clean Energy for the amortization of differences between contract prices and estimated market prices for PSAs that were assumed during the acquisition of various wind energy facilities. Revenue Recognition. Revenue is recognized upon transfer of control of promised goods or services to our customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. Revenue is recognized net of allowance for returns and any taxes collected from customers, which are subsequently remitted to the appropriate governmental authorities. We account for shipping and handling activities that occur after the customer obtains control of goods as a cost rather than an additional performance obligation thereby recognizing revenue at time of shipment and accruing shipping and handling costs when control transfers to our customers. We have a right to consideration from our customers in an amount that corresponds directly with the value to the customer for our performance completed to date; therefore, we may recognize revenue in the amount to which we have a right to invoice. ALLETE, Inc. 2021 Form 10-K 79 NOTE 1. OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (Continued) Revenue (Continued) Nature of Revenue Streams Utility Residential and Commercial includes sales for electric, gas or water service to customers, who have implied contracts with the utility, under rates governed by the MPUC, PSCW or FERC. Customers are billed on a monthly cycle basis and revenue is recognized for electric, gas or water service delivered during the billing period. Revenue is accrued for service provided but not yet billed at period end. Performance obligations with these customers are satisfied at time of delivery to customer meters and simultaneously consumed. Municipal includes sales to 15 non-affiliated municipal customers in Minnesota under long-term wholesale electric contracts. All wholesale electric contracts include a termination clause requiring a three-year notice to terminate. These contracts have termination dates ranging through 2037, with a majority of contracts effective through 2029. Performance obligations with these customers are satisfied at the time energy is delivered to an agreed upon municipal substation or meter. Industrial includes sales recognized from contracts with customers in the taconite mining, paper, pulp and secondary wood products, pipeline and other industries. Industrial sales accounted for approximately 47 percent of total regulated utility kWh sales for the year ended December 31, 2021. Within industrial revenue, Minnesota Power had eight Large Power Customer contracts, each serving requirements of 10 MW or more of customer load as of December 31, 2021. These contracts automatically renew past the contract term unless a four-year advanced written notice is given. Large Power Customer contracts have earliest termination dates ranging from 2025 through 2029. In January 2021, Verso Corporation provided notice of termination for its contract. Minnesota Power and Verso Corporation mutually agreed to resolve the outstanding commitments under the contract in January 2022. We satisfy our performance obligations for these customers at the time energy is delivered to an agreed upon customer substation. Revenue is accrued for energy provided but not yet billed at period end. Based on current contracts with industrial customers, we expect to recognize minimum revenue for the fixed contract components of approximately $50 million per annum through 2025, $15 million in 2026, and $30 million in total thereafter, which reflects the termination notice period in these contracts. When determining minimum revenue, we assume that customer contracts will continue under the contract renewal provision; however, if long-term contracts are renegotiated and subsequently approved by the MPUC or there are changes within our industrial customer class, these amounts may be impacted. Contracts with customers that contain variable pricing or quantity components are excluded from the expected minimum revenue amounts. Other Power Suppliers includes the sale of energy under a long-term PSA with one customer as well as MISO market and liquidation sales. The expiration date of this PSA is 2028. Performance obligations with these customers are satisfied at the time energy is delivered to an agreed upon delivery point defined in the contract (generally the MISO pricing node). The current contract with one customer contains variable pricing components that prevent us from estimating future minimum revenue. Other Revenue includes all remaining individually immaterial revenue streams for Minnesota Power and SWL&P, and is comprised of steam sales to paper and pulp mills, wheeling revenue and other sources. Revenue for steam sales to customers is recognized at the time steam is delivered and simultaneously consumed. Revenue is recognized at the time each performance obligation is satisfied. CIP Financial Incentive reflects certain revenue that is a result of the achievement of certain objectives for our CIP financial incentives. This revenue is accounted for in accordance with the accounting standards for alternative revenue programs which allow for the recognition of revenue under an alternative revenue program if the program is established by an order from the utility’s regulatory commission, the order allows for automatic adjustment of future rates, the amount of revenue recognized is objectively determinable and probable of recovery, and the revenue will be collected within 24 months following the end of the annual period in which it is recognized. CIP financial incentives are recognized in the period in which the MPUC approves the filing, which is typically mid-year. ALLETE, Inc. 2021 Form 10-K 80 NOTE 1. OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (Continued) Revenue (Continued) Non-utility ALLETE Clean Energy Long-term PSA revenue includes all sales recognized under long-term contracts for production, curtailment, capacity and associated renewable energy credits from ALLETE Clean Energy wind energy facilities. Expiration dates of these PSAs range from 2022 through 2039. Performance obligations for these contracts are satisfied at the time energy is delivered to an agreed upon point, or production is curtailed at the request of the customer, at specified prices. Revenue from the sale of renewable energy credits is recognized at the same time the related energy is delivered to the customer when sold to the same party. Sale of Wind Energy Facility includes revenue recognized for the design, development, construction, and sale of a wind energy facility to a customer. Performance obligations for these types of agreements are satisfied at the time the completed project is transferred to the customer at the commercial operation date. Revenue from the sale of a wind energy facility is recognized at the time of asset transfer. Other is the non-cash adjustments to revenue recognized by ALLETE Clean Energy for the amortization of differences between contract prices and estimated market prices on assumed PSAs. As part of wind energy facility acquisitions, ALLETE Clean Energy assumed various PSAs that were above or below estimated market prices at the time of acquisition; the resulting differences between contract prices and estimated market prices are amortized to revenue over the remaining PSA term. U.S. Water Services In 2019, ALLETE completed the sale of U.S. Water Services. Prior to the sale, ALLETE recognized revenue under the point-in-time, contract and capital project streams. Point-in-time revenue was recognized for purchases by customers for chemicals, consumable equipment or related maintenance and repair services as the customer’s usage and needs changed over time. Contract revenue included monthly revenue from contracts with customers to provide chemicals, consumable equipment and services to meet customer needs during the contract period at a fixed monthly price. Capital Project revenue was recognized at the time of sale when equipment and other components were assembled to create a water treatment system for a customer. Corporate and Other Long-term Contract encompasses the sale and delivery of coal to customer generation facilities. Revenue is recognized on a monthly basis at the cost of production plus a specified profit per ton of coal delivered to the customer. Coal sales are secured under long-term coal supply agreements extending through 2037. Performance obligations are satisfied during the period as coal is delivered to customer generation facilities. Other primarily includes revenue from BNI Energy unrelated to coal, the sale of real estate from ALLETE Properties, and non‑rate base steam generation that is sold for use during production of paper and pulp. Performance obligations are satisfied when control transfers to the customer. Payment Terms Payment terms and conditions vary across our businesses. Aside from taconite-producing Large Power Customers, payment terms generally require payment to be made within 15 to 30 days from the end of the period that the service has been rendered. In the case of its taconite-producing Large Power Customers, as permitted by the MPUC, Minnesota Power requires weekly payments for electric usage based on monthly energy usage estimates. These customers receive estimated bills based on Minnesota Power’s estimate of the customers’ energy usage, forecasted energy prices and fuel adjustment clause estimates. Minnesota Power’s taconite-producing Large Power Customers have generally predictable energy usage on a weekly basis and any differences that occur are trued-up the following month. Due to the timing difference of revenue recognition from the timing of invoicing and payment, the taconite- producing Large Power Customers receive credit for the time value of money; however, we have determined that our contracts do not include a significant financing component as the period between when we transfer the service to the customer and when they pay for such service is minimal. ALLETE, Inc. 2021 Form 10-K 81 NOTE 1. OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (Continued) Revenue (Continued) Assets Recognized From the Costs to Obtain a Contract with a Customer We recognize as an asset the incremental costs of obtaining a contract with a customer if we expect the benefit of those costs to be longer than one year. We expense incremental costs when the asset that would have resulted from capitalizing these costs would have been amortized in one year or less. As of December 31, 2021, we have $23.3 million of assets recognized for costs incurred to obtain contracts with our customers ($25.5 million as of December 31, 2020). Management determined the amount of costs to be recognized as assets based on actual costs incurred and paid to obtain and fulfill these contracts to provide goods and services to our customers. Assets recognized to obtain contracts are amortized on a straight-line basis over the contract term as a non- cash reduction to revenue. We recognized $2.7 million of non-cash amortization for the year ended December 31, 2021 ($2.6 million for the year end December 31, 2020). Unamortized Discount and Premium on Debt. Discount and premium on debt are deferred and amortized over the terms of the related debt instruments using a method which approximates the effective interest method. Tax Equity Financings. Certain subsidiaries of ALLETE have entered into tax equity financings that include forming limited liability companies (LLC) with third-party investors for certain wind projects. Tax equity financings have specific terms that dictate distributions of cash and the allocation of tax attributes among the LLC members, who are divided into two categories: the sponsor and third-party investors. ALLETE subsidiaries are the sponsors in these tax equity financings. The distributions of cash and allocation of tax attributes in these financings generally differ from the underlying percentage ownership interests in the related LLC, with a disproportionate share of tax attributes (including accelerated depreciation and production tax credits) allocated to third-party investors in order to achieve targeted after-tax rates of return, or target yield, from project operations, and a disproportionate share of cash distributions made to the sponsor. The target yield and other terms vary by tax equity financing. Once the target yield has been achieved, a “flip point” is recognized. In addition, tax equity financings typically provide that cash distributions can be temporarily increased to the third-party investors in order to meet cumulative distribution thresholds. After the flip point, tax attributes and cash distributions are both typically disproportionately allocated to the sponsor. Tax equity financings include affirmative and negative covenants that are similar to what a project lender would require in a project financing, such as financial reporting, insurance, maintenance and prudent operator standards. Most covenants are no longer applicable once the flip point occurs and any other obligations of the third-party investor have been eliminated. The third-party investors’ portions of equity ownership in tax equity LLCs are recorded as non-controlling interest in subsidiaries on the Consolidated Balance Sheet and earnings allocated to third-party investors are recorded as net loss attributable to non-controlling interest on the Consolidated Statement of Income. Non-Controlling Interest in Subsidiaries. Non-controlling interest in subsidiaries represents the portion of equity ownership, net income (loss), and comprehensive income (loss) in subsidiaries that is not attributable to equity holders of ALLETE. These amounts as of and for the years ended December 31, 2021 and 2020, related to the tax equity financings for ALLETE Clean Energy’s 106 MW Glen Ullin, 80 MW South Peak, 303 MW Diamond Spring and 303 MW Caddo wind energy facilities as well as ALLETE’s equity investment in the 250 MW Nobles 2 wind energy facility. For those wind projects with tax equity financings where the economic benefits are not allocated based on the underlying ownership percentage interests, we have determined that the appropriate methodology for calculating the non-controlling interest in subsidiaries balance is the hypothetical liquidation at book value (HLBV) method. The HLBV method is a balance sheet approach which reflects the substantive economic arrangements in the tax equity financing structures. ALLETE, Inc. 2021 Form 10-K 82 NOTE 1. OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (Continued) Non-Controlling Interest in Subsidiaries (Continued) Under the HLBV method, amounts reported as non-controlling interest in subsidiaries on the Consolidated Balance Sheet represent the amounts the third- party investors would hypothetically receive at each balance sheet reporting date under the liquidation provisions of the LLC agreements, assuming the net assets of the wind projects were liquidated at amounts determined in accordance with GAAP and distributed to the third-party investor and sponsor. The resulting non-controlling interest in subsidiaries balance in these projects is reported as a component of equity on the Consolidated Balance Sheet. The results of operations for these projects attributable to non-controlling interest under the HLBV method is determined as the difference in non- controlling interest in subsidiaries on the Consolidated Balance Sheet at the start and end of each reporting period, after taking into account any capital transactions between the projects and the third-party investors. Factors used in the HLBV calculation include GAAP income, taxable income (loss), tax attributes such as accelerated depreciation and production tax credits, capital contributions, cash distributions, and the target yield specified in the corresponding LLC agreement. Changes in these factors could have a significant impact on the amounts that third-party investors and sponsors would receive upon a hypothetical liquidation. The use of the HLBV method to allocate income to the non-controlling interest in subsidiaries may create variability in our results of operations as the application of the HLBV method can drive variability in net income or loss attributable to non-controlling interest in subsidiaries from period to period.

We account for income taxes using the liability method in accordance with GAAP for income taxes. Under the liability method, deferred income tax assets and liabilities are established for all temporary differences in the book and tax basis of assets and liabilities, based upon enacted tax laws and rates applicable to the periods in which the taxes become payable. Due to the effects of regulation on Minnesota Power and SWL&P, certain adjustments made to deferred income taxes are, in turn, recorded as regulatory assets or liabilities. Federal investment tax credits have been recorded as deferred credits and are being amortized to income tax expense over the service lives of the related property. In accordance with GAAP for uncertainty in income taxes, we are required to recognize in our financial statements the largest tax benefit of a tax position that is “more‑likely‑than‑not” to be sustained on audit, based solely on the technical merits of the position as of the reporting date. The term “more‑likely‑than‑not” means more than 50 percent likely. (See Note 10. Income Tax Expense.) Excise Taxes. We collect excise taxes from our customers levied by governmental entities. These taxes are stated separately on the billing to the customer and recorded as a liability to be remitted to the governmental entity. We account for the collection and payment of these taxes on a net basis. ALLETE, Inc. 2021 Form 10-K 83 NOTE 2.

PROPERTY, PLANT AND EQUIPMENT (Continued) Asset Retirement Obligations. We recognize, at fair value, obligations associated with the retirement of certain tangible, long‑lived assets that result from the acquisition, construction, development or normal operation of the asset. Asset retirement obligations (AROs) relate primarily to the decommissioning of our coal-fired and wind energy facilities, and land reclamation at BNI Energy. AROs are included in Other Non-Current Liabilities on the Consolidated Balance Sheet. The associated retirement costs are capitalized as part of the related long-lived asset and depreciated over the useful life of the asset. Removal costs associated with certain distribution and transmission assets have not been recognized, as these facilities have indeterminate useful lives. Conditional asset retirement obligations have been identified for treated wood poles and remaining polychlorinated biphenyl and asbestos-containing assets; however, the period of remediation is indeterminable and removal liabilities have not been recognized. Long-standing ratemaking practices approved by applicable state and federal regulatory authorities have allowed provisions for future plant removal costs in depreciation rates. These plant removal cost recoveries are classified either as AROs or as a regulatory liability for non-AROs. To the extent annual accruals for plant removal costs differ from accruals under approved depreciation rates, a regulatory asset has been established in accordance with GAAP for AROs. (See Note 4.

While Minnesota Power operates the plant, certain decisions about the operations of Boswell Unit 4 are subject to the oversight of a committee on which it and WPPI Energy, the owner of the remaining 20 percent, have equal representation and voting rights. Each owner must provide its own financing and is obligated to its ownership share of operating costs. Minnesota Power’s share of operating expenses for Boswell Unit 4 is included in Operating Expenses on the Consolidated Statement of Income. ALLETE, Inc. 2021 Form 10-K 85 NOTE 3.

Entities within our Regulated Operations segment file for periodic rate revisions with the MPUC, PSCW or FERC. As authorized by the MPUC, Minnesota Power also recognizes revenue under cost recovery riders for transmission, renewable and environmental investments and expenditures. (See Transmission Cost Recovery Rider, Renewable Cost Recovery Rider, Solar Cost Recovery Rider and Environmental Improvement Rider.) Revenue from cost recovery riders was $38.9 million in 2021 ($29.9 million in 2020; $31.8 million in 2019). 2020 Minnesota General Rate Case. In November 2019, Minnesota Power filed a retail rate increase request with the MPUC seeking an average increase of approximately 10.6 percent for retail customers. The rate filing sought a return on equity of 10.05 percent and a 53.81 percent equity ratio. On an annualized basis, the requested final rate increase would have generated approximately $66 million in additional revenue. In December 2019 orders, the MPUC accepted the filing as complete and authorized an annual interim rate increase of $36.1 million beginning January 1, 2020. In April 2020, Minnesota Power filed a request with the MPUC that proposed a resolution of Minnesota Power’s 2020 general rate case. Key components of our proposal included removing the power marketing margin credit in base rates and reflecting actual power marketing margins in the fuel adjustment clause effective May 1, 2020; refunding to customers interim rates collected through April 2020; increasing customer rates 4.1 percent compared to the 5.8 percent increase reflected in interim rates; and a provision that Minnesota Power would not file another rate case until at least November 1, 2021, unless certain events occur. In a June 2020 order, the MPUC approved Minnesota Power’s petition and proposal to resolve and withdraw the general rate case. Effective May 1, 2020, customer rates were set at an increase of 4.1 percent with the removal of the power marketing margin credit from base rates. Actual power marketing margins will be reflected in the fuel adjustment clause. Reserves for interim rates of $11.7 million were recorded in the second quarter of 2020 and refunded in the third and fourth quarters of 2020. 2022 Minnesota General Rate Case. On November 1, 2021, Minnesota Power filed a retail rate increase request with the MPUC seeking an average increase of approximately 18 percent for retail customers. The rate filing seeks a return on equity of 10.25 percent and a 53.81 percent equity ratio. On an annualized basis, the requested final rate increase would generate approximately $108 million in additional revenue. In orders dated December 30, 2021, the MPUC accepted the filing as complete and authorized an annual interim rate increase beginning January 1, 2022, with approximately $80 million expected to be collected in cash and approximately $8 million of interim rates for residential customers deferred with a final determination on recovery at the end of the rate case. ALLETE, Inc. 2021 Form 10-K 86 NOTE 4. REGULATORY MATTERS (Continued) Electric Rates (Continued) Minnesota Power Land Sales. In August 2020, Minnesota Power filed a petition with the MPUC for approval to sell land that surrounds several reservoirs on its hydroelectric system and is no longer required to maintain its operations. The land has an estimated value of approximately $100 million, and Minnesota Power proposed to credit ratepayers the net proceeds from the sales in a future rate case or through its renewable resources rider to mitigate future rate increases. In an order dated November 18, 2021, the MPUC authorized the land sales and directed the net proceeds to be refunded to ratepayers subject to certain conditions and required compliance filings. FERC-Approved Wholesale Rates. Minnesota Power has wholesale contracts with 15 non-affiliated municipal customers in Minnesota and SWL&P. Three of the wholesale contracts include a termination clause requiring a three-year notice to terminate. Minnesota Power’s wholesale electric contract with the Nashwauk Public Utilities Commission was extended in October 2020 and is effective through December 31, 2037. The wholesale electric service contract with SWL&P is effective through February 28, 2025. Under the agreement with SWL&P, no termination notice has been given. The rates included in these two contracts are set each July 1 based on a cost-based formula methodology, using estimated costs and a rate of return that is equal to Minnesota Power’s authorized rate of return for Minnesota retail customers. The formula-based rate methodology also provides for a yearly true-up calculation for actual costs incurred. Minnesota Power’s wholesale electric contracts with 13 other municipal customers were extended in January 2022 and are effective through 2029. These contracts are based on fixed prices for capacity and energy. The base energy charge for each year is adjusted annually for updated fuel and purchased power costs. The wholesale electric contract with one other municipal customer is effective through 2024. The capacity charge is determined using a cost-based formula methodology with limits on the annual change from the previous year’s capacity charge. The base energy charge for each year of the contract term is set each January 1, subject to monthly adjustment, and is determined using a cost-based formula methodology. Transmission Cost Recovery Rider. Minnesota Power has an approved cost recovery rider in place to charge retail customers on a current basis for certain transmission investments and expenditures, including a return on the capital invested. Current customer billing rates are based on a December 2020 order. In December 2020, Minnesota Power filed a petition seeking MPUC approval to update customer billing rates for additional investments made for the GNTL. On December 28, 2021, Minnesota Power submitted its annual factor filing seeking MPUC approval to further update customer billing rates under the transmission cost recovery rider. Renewable Cost Recovery Rider. Minnesota Power has an approved cost recovery rider in place to charge retail customers on a current basis for the costs of certain renewable investments and expenditures, including a return on the capital invested. Current customer billing rates for the renewable cost recovery rider were approved by the MPUC in a December 2020 order. On February 2, 2022, Minnesota Power submitted its 2022 renewable factor filing. Upon approval of the filing, Minnesota Power will be authorized to include updated billing rates on customer bills. Solar Cost Recovery Rider. In June 2020, Minnesota Power filed a petition seeking MPUC approval of a customer billing rate for solar costs related to investments and expenditures for meeting the state of Minnesota’s solar energy standard, which was approved by the MPUC in an order dated April 20, 2021. New customer billing rates for the solar cost recovery rider were implemented on June 1, 2021. On October 21, 2021, Minnesota Power submitted its 2022 solar factor filing. Upon approval of the filing, Minnesota Power will be authorized to include updated billing rates on customer bills. Environmental Improvement Rider. Minnesota Power has an approved environmental improvement rider for investments and expenditures related to the implementation of the Boswell Unit 4 mercury emissions reduction plan completed in 2015. Updated customer billing rates for the environmental improvement rider were approved by the MPUC in a November 2018 order. On January 19, 2021, Minnesota Power filed a petition seeking MPUC approval to end the environmental improvement rider, which was approved in an order dated April 20, 2021. The environmental improvement rider ended effective October 1, 2021. Electric Vehicle Charging Infrastructure Petition. On April 8, 2021, Minnesota Power filed a petition seeking approval to install and own DC fast charger stations for electric vehicles across its service territory, implement accompanying rates for those stations, and track and recover investments and expenses for the project. In an order dated October 22, 2021, the MPUC approved Minnesota Power’s petition. ALLETE, Inc. 2021 Form 10-K 87 NOTE 4. REGULATORY MATTERS (Continued) Electric Rates (Continued) Fuel Adjustment Clause. The costs of fuel and related transportation costs for Minnesota Power’s generation as well as costs of purchased power for Minnesota Power are recoverable from Minnesota Power’s utility retail customers through the fuel adjustment clause (FAC). The FAC for Minnesota electric utilities is a monthly budgeted, forward-looking process with annual prudence review and true-up to actual allowed costs. In May 2020, Minnesota Power filed its fuel adjustment forecast for 2021, which was approved by the MPUC in a December 2020 order, subject to the annual prudence review and true-up filing in 2022. During 2021, Minnesota Power incurred higher fuel and purchased power costs than those forecasted in its May 2020 filing, which resulted in the recognition of an approximately $56 million regulatory asset as of December 31, 2021. Minnesota Power will make its annual true-up filing and a significant events filing in March 2022 requesting recovery of these under-collected fuel adjustment clause recoveries. In March 2020, Minnesota Power filed its FAC report covering the period July 2018 through December 2019. In a September 2020 order, the MPUC referred the review of Minnesota Power’s forced outage costs during the period of the report, which totaled approximately $8 million, to an administrative law judge (ALJ) for a contested case hearing to recommend to the MPUC if any of those costs should be returned to customers. On August 11, 2021, the ALJ recommended that Minnesota Power refund approximately $5 million to ratepayers. Minnesota Power submitted exceptions to the ALJ’s report to the MPUC stating that it disagreed with the ALJ’s recommendation and that no refund should be made as the Company operated its facilities in accordance with good utility practice. At a hearing on January 13, 2022, the MPUC agreed with the ALJ’s recommendation and ordered the refund of approximately $5 million to ratepayers, which was recorded as a reserve as of December 31, 2021. COVID-19 Related Deferred Accounting. In a March 2020 order, the PSCW authorized public utilities, including SWL&P, to defer expenditures incurred by the utility resulting from its compliance with state government or regulator orders during Wisconsin’s declared public health emergency for COVID- 19. In a May 2020 order, the MPUC required Minnesota Power along with other regulated electric and natural gas service providers in Minnesota to track cost and revenue impacts resulting from the COVID-19 pandemic with review for recovery in a future rate proceeding. As of December 31, 2021, Minnesota Power has not deferred any costs or lost revenue, and SWL&P has deferred an immaterial amount of costs. Minnesota Power submitted a petition in November 2020 to the MPUC requesting authority to track and record as a regulatory asset lost large industrial customer revenue resulting from the idling of USS Corporation’s Keetac plant and Verso Corporation’s paper mill in Duluth, Minnesota. In an order dated May 13, 2021, the MPUC denied Minnesota Power’s request. 2018 Wisconsin General Rate Case. SWL&P’s current retail rates are based on a December 2018 order by the PSCW that allows for a return on equity of 10.4 percent and a 55.0 percent equity ratio. The PSCW had directed SWL&P to file its next general rate case in 2020; however, the PSCW granted an extension request made by SWL&P to delay filing its next general rate case until on or before December 20, 2022. SWL&P requested the extension primarily due to impacts of the COVID-19 pandemic. Integrated Resource Plan. In a 2016 order, the MPUC approved Minnesota Power’s 2015 IRP with modifications. The order accepted Minnesota Power’s plans for the economic idling of Taconite Harbor Units 1 and 2 and the ceasing of coal-fired operations at Taconite Harbor in 2020, directed Minnesota Power to retire Boswell Units 1 and 2, required an analysis of generation and demand response alternatives to be filed with a natural gas resource proposal, and required Minnesota Power to conduct requests for proposal for additional wind, solar and demand response resource additions. Minnesota Power retired Boswell Units 1 and 2 in the fourth quarter of 2018. 2021 Integrated Resource Plan. On February 1, 2021, Minnesota Power filed its latest IRP with the MPUC, which outlines its clean-energy transition plans through 2035. These plans include expanding its renewable energy supply, achieving coal-free operations at its facilities by 2035, and investing in a resilient and flexible transmission and distribution grid. As part of these plans, Minnesota Power anticipates adding approximately 400 MW of new wind and solar energy resources, retiring Boswell Unit 3 by 2030 and transforming Boswell Unit 4 to be coal-free by 2035. Minnesota Power’s plans recognize that advances in technology will play a significant role in completing its transition to carbon-free energy supply, reliably and affordably. A final decision on the IRP is expected in the second half of 2022. ALLETE, Inc. 2021 Form 10-K 88 NOTE 4. REGULATORY MATTERS (Continued) Nemadji Trail Energy Center. In 2017, Minnesota Power submitted a resource package to the MPUC which included requesting approval of a natural gas capacity dedication and other affiliated-interest agreements for NTEC, an approximately 600 MW proposed combined-cycle natural gas-fired generating facility to be built in Superior, Wisconsin, which will be jointly owned by Dairyland Power Cooperative, Basin and South Shore Energy, ALLETE’s non- rate regulated, Wisconsin subsidiary. Minnesota Power is expected to purchase approximately 20 percent of the facility's output starting in 2025 pursuant to the capacity dedication agreement. (See Note 1. Operations and Significant Accounting Policies.) In a January 2019 order, the MPUC approved Minnesota Power’s request for approval of the NTEC natural gas capacity dedication and other affiliated-interest agreements. In 2019, the Minnesota Court of Appeals reversed and remanded the MPUC’s decision to approve certain affiliated-interest agreements. On April 21, 2021, the Minnesota Supreme Court reversed the Minnesota Court of Appeal’s decision by ruling that the MPUC is not required to conduct a review under the Minnesota Environmental Policy Act before approving affiliated-interest agreements that govern construction and operation of a Wisconsin power plant by a Minnesota utility, and remanded the case back to the Minnesota Court of Appeals for review of remaining issues on appeal. On August 23, 2021, the Minnesota Court of Appeals affirmed the decision by the MPUC to approve certain affiliated-interest agreements. Conservation Improvement Program. Minnesota requires electric utilities to spend a minimum of 1.5 percent of gross operating revenues, excluding revenue received from exempt customers, from service provided in the state on energy CIPs each year. On April 1, 2021, Minnesota Power submitted its 2020 consolidated filing detailing Minnesota Power’s CIP program results and requesting a CIP financial incentive of $2.4 million based upon MPUC procedures, which was recognized in the third quarter of 2021 upon approval by the MPUC in an order dated September 7, 2021. In 2020, a CIP financial incentive of $2.4 million was recognized in the third quarter upon approval by the MPUC of Minnesota Power’s 2019 CIP consolidated filing. CIP financial incentives are recognized in the period in which the MPUC approves the filing. In July 2020, Minnesota Power submitted its CIP triennial filing for 2021 through 2023 to the MPUC and Minnesota Department of Commerce, which outlines Minnesota Power’s CIP spending and energy-saving goals for those years. Minnesota Power’s CIP investment goals are $10.7 million for 2022 and $10.9 million for 2023. MISO Return on Equity Complaint. MISO transmission owners, including ALLETE and ATC, have an authorized return on equity of 10.02 percent, or 10.52 percent including an incentive adder for participation in a regional transmission organization based on a 2020 FERC order that granted rehearing of a 2019 FERC order. These FERC orders are subject to various outstanding legal challenges related to the refund period ordered by the FERC. Minnesota Solar Energy Standard. Minnesota law requires at least 1.5 percent of total retail electric sales, excluding sales to certain customers, to be generated by solar energy. At least 10 percent of the 1.5 percent mandate must be met by solar energy generated by or procured from solar photovoltaic devices with a nameplate capacity of 40 kW or less and community solar garden subscriptions. Minnesota Power has met both parts of the solar mandate to date. In May 2020, the MPUC issued a notice requesting all regulated gas and electric utilities provide a list of all ongoing, planned, or possible investments that support Minnesota’s energy policy objectives and aid economic recovery in Minnesota, among other items. In June 2020, Minnesota Power filed proposal with the MPUC to accelerate its plans for purchasing solar energy from approximately 20 MW of solar energy projects in Minnesota which was approved in a June 2021 order. These solar energy projects will be constructed and owned through an ALLETE subsidiary with an estimated investment of $40 million. Construction of these solar energy projects is expected to commence in 2022. Regulatory Assets and Liabilities. Our regulated utility operations are subject to accounting standards for the effects of certain types of regulation. Regulatory assets represent incurred costs that have been deferred as they are probable for recovery in customer rates. Regulatory liabilities represent obligations to make refunds to customers and amounts collected in rates for which the related costs have not yet been incurred. The Company assesses quarterly whether regulatory assets and liabilities meet the criteria for probability of future recovery or deferral. With the exception of the regulatory asset for Boswell Units 1 and 2 net plant and equipment, no other regulatory assets are currently earning a return. The recovery, refund or credit to rates for these regulatory assets and liabilities will occur over the periods either specified by the applicable regulatory authority or over the corresponding period related to the asset or liability.

These FERC orders are subject to various outstanding legal challenges related to the refund period ordered by the FERC. If these legal challenges are successful, ATC may be required to provide refunds to its customers of up to approximately $65 million of which our share would be approximately $5 million pre-tax. In addition, the FERC issued a Notice of Proposed Rulemaking in April 2021 proposing to limit the 50 basis point incentive adder for participation in a regional transmission organization to only the first three years of membership in such an organization. If this proposal is adopted, our equity in earnings from ATC would be reduced by approximately $1 million pre-tax annually. ALLETE, Inc. 2021 Form 10-K 91 NOTE 5.

NOTE 6. FAIR VALUE Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). We utilize market data or assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market corroborated, or generally unobservable. We primarily apply the market approach for recurring fair value measurements and endeavor to utilize the best available information. Accordingly, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. These inputs, which are used to measure fair value, are prioritized through the fair value hierarchy. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). The three levels of the fair value hierarchy are as follows: Level 1 — Quoted prices are available in active markets for identical assets or liabilities as of the reported date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis. This category includes primarily equity securities. Level 2 — Pricing inputs are other than quoted prices in active markets, but are either directly or indirectly observable as of the reported date. The types of assets and liabilities included in Level 2 are typically either comparable to actively traded securities or contracts, such as treasury securities with pricing interpolated from recent trades of similar securities, or priced with models using highly observable inputs, such as commodity options priced using observable forward prices and volatilities. This category includes deferred compensation and fixed income securities. Level 3 — Significant inputs that are generally less observable from objective sources. The types of assets and liabilities included in Level 3 are those with inputs requiring significant management judgment or estimation, such as the complex and subjective models and forecasts used to determine the fair value. ALLETE, Inc. 2021 Form 10-K 92 NOTE 6. FAIR VALUE (Continued) The following tables set forth by level within the fair value hierarchy, our assets and liabilities that were accounted for at fair value on a recurring basis as of December 31, 2021, and December 31, 2020. Each asset and liability is classified based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement requires judgment, which may affect the valuation of these assets and liabilities and their placement within the fair value hierarchy levels. The estimated fair value of Cash and Cash Equivalents listed on the Consolidated Balance Sheet approximates the carrying amount and therefore is excluded from the recurring fair value measures in the following tables.

For the years ended December 31, 2021 and 2020, there were no transfers in or out of Levels 1, 2 or 3. Fair Value of Financial Instruments. With the exception of the item listed in the following table, the estimated fair value of all financial instruments approximates the carrying amount. The fair value for the item listed in the following table was based on quoted market prices for the same or similar instruments (Level 2). ALLETE, Inc. 2021 Form 10-K 93 NOTE 6.

Carrying Amount Fair Value $1,986.4 $1,806.4 $2,192.6 $2,122.0 Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis. Non-financial assets such as equity method investments, goodwill, intangible assets, and property, plant and equipment are measured at fair value when there is an indicator of impairment and recorded at fair value only when an impairment is recognized. Equity Method Investments. The aggregate carrying amount of our equity investments was $318.0 million as of December 31, 2021 ($301.2 million as of December 31, 2020). The Company assesses our equity investments in ATC and Nobles 2 for impairment whenever events or changes in circumstances indicate that the carrying amount of our investments may not be recoverable. For the years ended December 31, 2021 and 2020, there were no indicators of impairment. (See Note 5. Equity Investments.) Property, Plant and Equipment. The Company assesses the impairment of property, plant, and equipment whenever events or changes in circumstances indicate that the carrying amount of property, plant, and equipment assets may not be recoverable. (See Note 1. Operations and Significant Accounting Policies.) For the years ended December 31, 2021, and 2020, there was no impairment of property, plant, and equipment. We believe that long-standing ratemaking practices approved by applicable state and federal regulatory commissions allow for the recovery of the remaining book value of retired plant assets. Minnesota Power’s 2015 IRP contained steps in Minnesota Power’s EnergyForward plan including the economic idling of Taconite Harbor Units 1 and 2 in 2016, and the ceasing of coal-fired operations at Taconite Harbor in 2020. As of December 31, 2021, Taconite Harbor had a net book value of approximately $45 million. The MPUC order for the 2015 IRP also directed Minnesota Power to retire Boswell Units 1 and 2, which occurred in the fourth quarter of 2018. As part of the 2016 general retail rate case, the MPUC allowed recovery of the remaining book value of Boswell Units 1 and 2 through 2022. In its latest IRP filing, Minnesota Power proposed retiring Boswell Unit 3 by 2030 and transforming Boswell Unit 4 to be coal-free by 2035. Boswell Unit 3 and Unit 4 have a net book value of approximately $245 million and $435 million, respectively, as of December 31, 2021. (See Note 4. Regulatory Matters.) We do not expect to record any impairment charge as a result of these operating changes at Taconite Harbor and Boswell. In addition, we expect to be able to continue depreciating these assets for at least their established remaining useful lives; however, we are unable to predict the impact of regulatory outcomes resulting in changes to their established remaining useful lives. NOTE 7. SHORT-TERM AND LONG-TERM DEBT Short-Term Debt. As of December 31, 2021, total short-term debt outstanding was $214.2 million ($203.7 million as of December 31, 2020), and consisted of long-term debt due within one year and included $0.2 million of unamortized debt issuance costs. As of December 31, 2021, we had consolidated bank lines of credit aggregating $432.0 million ($407.0 million as of December 31, 2020), most of which expire in January 2025. We had $31.5 million outstanding in standby letters of credit and $159.7 million outstanding draws under our lines of credit as of December 31, 2021 ($22.3 million in standby letters of credit and no outstanding draws as of December 31, 2020). ALLETE, Inc. 2021 Form 10-K 94 NOTE 7. SHORT-TERM AND LONG-TERM DEBT (Continued) Long-Term Debt. As of December 31, 2021, total long-term debt outstanding was $1,763.2 million ($1,593.2 million as of December 31, 2020) and included $8.8 million of unamortized debt issuance costs. The aggregate amount of long-term debt maturing in 2022 is $214.5 million; $89.7 million in 2023; $74.4 million in 2024; $386.7 million in 2025; $77.2 million in 2026; and $1,143.9 million thereafter. Substantially all of our regulated electric plant is subject to the lien of the mortgages collateralizing outstanding first mortgage bonds. The mortgages contain non-financial covenants customary in utility mortgages, including restrictions on our ability to incur liens, dispose of assets, and merge with other entities. Minnesota Power is obligated to make financing payments for the Camp Ripley solar array totaling $1.4 million annually during the financing term, which expires in 2027. Minnesota Power has the option at the end of the financing term to renew for a two‑year term, or to purchase the solar array for approximately $4 million. Minnesota Power anticipates exercising the purchase option when the term expires. On March 25, 2021, ALLETE entered into a $150 million unsecured term loan agreement (Term Loan). An additional draw of $35 million through the exercise of an accordion feature was made during the second quarter of 2021. As of September 30, 2021, we have borrowed the full amount of $185 million. The Term Loan is due March 24, 2022, and may be repaid at any time. Interest is payable monthly at a rate per annum equal to LIBOR plus 0.75 percent. Proceeds from the Term Loan were used for general corporate purposes. On September 1, 2021, ALLETE issued $100 million of its First Mortgage Bonds (Bonds) to certain institutional buyers in the private placement market. The Bonds, which bear interest at 2.79 percent, will mature in September 2031 and pay interest semi-annually in March and September of each year, commencing on March 1, 2022. ALLETE has the option to prepay all or a portion of the Bonds at its discretion, subject to a make-whole provision. The Bonds are subject to additional terms and conditions which are customary for these types of transactions. Proceeds from the sale of the Bonds were used to fund utility capital investment and for general corporate purposes. The Bonds were sold in reliance on an exemption from registration under Section 4(a)(2) of the Securities Act of 1933, as amended, to institutional accredited investors. In January 2022, ALLETE Clean Energy received approximately $183.0 million from final closing of tax equity funding for the Caddo wind energy facility. The proceeds from the funding were used to pay down a portion of outstanding draws on our lines of credit. ALLETE, Inc. 2021 Form 10-K 95 NOTE 7.

SHORT-TERM AND LONG-TERM DEBT (Continued) Long-Term Debt (Continued) Financial Covenants. Our long-term debt arrangements contain customary covenants. In addition, our lines of credit and letters of credit supporting certain long-term debt arrangements contain financial covenants. Our compliance with financial covenants is not dependent on debt ratings. The most restrictive financial covenant requires ALLETE to maintain a ratio of indebtedness to total capitalization (as the amounts are calculated in accordance with the respective long-term debt arrangements) of less than or equal to 0.65 to 1.00, measured quarterly. As of December 31, 2021, our ratio was approximately 0.41 to 1.00. Failure to meet this covenant would give rise to an event of default if not cured after notice from the lender, in which event ALLETE may need to pursue alternative sources of funding. Some of ALLETE’s debt arrangements contain “cross-default” provisions that would result in an event of default if there is a failure under other financing arrangements to meet payment terms or to observe other covenants that would result in an acceleration of payments due. ALLETE has no significant restrictions on its ability to pay dividends from retained earnings or net income. As of December 31, 2021, ALLETE was in compliance with its financial covenants. NOTE 8.

(See Power Purchase Agreements.) (c) Consists of long-term service agreements for wind energy facilities and minimum purchase commitments under coal and rail contracts. Power Purchase and Sales Agreements. Our long-term PPAs have been evaluated under the accounting guidance for variable interest entities. We have determined that either we have no variable interest in the PPAs, or where we do have variable interests, we are not the primary beneficiary; therefore, consolidation is not required. These conclusions are based on the fact that we do not have both control over activities that are most significant to the entity and an obligation to absorb losses or receive benefits from the entity’s performance. Our financial exposure relating to these PPAs is limited to our capacity and energy payments. These agreements have also been evaluated under the accounting guidance for derivatives. We have determined that either these agreements are not derivatives, or, if they are derivatives, the agreements qualify for the normal purchases and normal sales exception to derivative accounting guidance; therefore, derivative accounting is not required. Square Butte PPA. Minnesota Power has a PPA with Square Butte that extends through 2026 (Agreement). Minnesota Power is obligated to pay its pro rata share of Square Butte’s costs based on its entitlement to the output of Square Butte’s 455 MW coal‑fired generating unit. Minnesota Power’s output entitlement under the Agreement is 50 percent for the remainder of the Agreement, subject to the provisions of the Minnkota Power PSA described in the following table. Minnesota Power’s payment obligation will be suspended if Square Butte fails to deliver any power, whether produced or purchased, for a period of one year. Square Butte’s costs consist primarily of debt service, operating and maintenance, depreciation and fuel expenses. As of December 31, 2021, Square Butte had total debt outstanding of $222.6 million. Annual debt service for Square Butte is expected to be approximately $45.5 million annually through 2023, $30.5 million in 2024, $26.6 million in 2025, and $40.1 million in 2026, of which Minnesota Power’s obligation is 50 percent. Fuel expenses are recoverable through Minnesota Power’s fuel adjustment clause and include the cost of coal purchased from BNI Energy under a long-term contract.

COMMITMENTS, GUARANTEES AND CONTINGENCIES (Continued) Power Purchase and Sales Agreements (Continued) Minnesota Power’s cost of power purchased from Square Butte during 2021 was $82.4 million ($79.5 million in 2020; $82.7 million in 2019). This reflects Minnesota Power’s pro rata share of total Square Butte costs based on the 50 percent output entitlement. Included in this amount was Minnesota Power’s pro rata share of interest expense of $5.8 million in 2021 ($7.1 million in 2020; $8.3 million in 2019). Minnesota Power’s payments to Square Butte are approved as a purchased power expense for ratemaking purposes by both the MPUC and the FERC.

(b) Minnesota Power is selling a portion of its entitlement from Square Butte to Minnkota Power, resulting in Minnkota Power’s net entitlement increasing and Minnesota Power’s net entitlement decreasing until Minnesota Power’s share is eliminated at the end of 2025. Of Minnesota Power’s 50 percent output entitlement, it sold to Minnkota Power approximately 28 percent in 2021 (28 percent in 2020 and in 2019). (See Square Butte PPA.) (c) Silver Bay Power supplies approximately 90 MW of load to Northshore Mining, an affiliate of Silver Bay Power, which had previously been served predominately through self-generation by Silver Bay Power. Minnesota Power now supplies the full energy requirements for Silver Bay Power. (d) The energy pricing escalates at a fixed rate annually and is adjusted for changes in a natural gas index. ALLETE, Inc. 2021 Form 10-K 98 NOTE 8. COMMITMENTS, GUARANTEES AND CONTINGENCIES (Continued) Coal, Rail and Shipping Contracts. Minnesota Power has coal supply agreements providing for the purchase of a significant portion of its coal requirements through December 2022. Minnesota Power also has coal transportation agreements in place for the delivery of a significant portion of its coal requirements through December 2024. The costs of fuel and related transportation costs for Minnesota Power’s generation are recoverable from Minnesota Power’s utility customers through the fuel adjustment clause. Environmental Matters. Our businesses are subject to regulation of environmental matters by various federal, state and local authorities. A number of regulatory changes to the Clean Air Act, the Clean Water Act and various waste management requirements have been promulgated by both the EPA and state authorities over the past several years. Minnesota Power’s facilities are subject to additional requirements under many of these regulations. Minnesota Power is reshaping its generation portfolio, over time, to reduce its reliance on coal, has installed cost-effective emission control technology, and advocates for sound science and policy during rulemaking implementation. We consider our businesses to be in substantial compliance with currently applicable environmental regulations and believe all necessary permits have been obtained. We anticipate that with many state and federal environmental regulations and requirements finalized, or to be finalized in the near future, potential expenditures for future environmental matters may be material and require significant capital investments. Minnesota Power has evaluated various environmental compliance scenarios using possible outcomes of environmental regulations to project power supply trends and impacts on customers. We review environmental matters on a quarterly basis. Accruals for environmental matters are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated based on current law and existing technologies. Accruals are adjusted as assessment and remediation efforts progress, or as additional technical or legal information becomes available. Accruals for environmental liabilities are included in the Consolidated Balance Sheet at undiscounted amounts and exclude claims for recoveries from insurance or other third parties. Costs related to environmental contamination treatment and cleanup are expensed unless recoverable in rates from customers. Air. The electric utility industry is regulated both at the federal and state level to address air emissions. Minnesota Power’s thermal generating facilities mainly burn low-sulfur western sub-bituminous coal. All of Minnesota Power’s coal-fired generating facilities are equipped with pollution control equipment such as scrubbers, baghouses and low NO technologies. Under currently applicable environmental regulations, these facilities are substantially compliant with emission requirements. X Cross-State Air Pollution Rule (CSAPR). The CSAPR requires certain states in the eastern half of the U.S., including Minnesota, to reduce power plant emissions that contribute to ozone or fine particulate pollution in other states. The CSAPR does not require installation of controls but does require facilities have sufficient allowances to cover their emissions on an annual basis. These allowances are allocated to facilities from each state’s annual budget, and can be bought and sold. Based on our review of the NO and SO allowances issued and pending issuance, we currently expect generation levels and emission rates will result in continued compliance with the CSAPR. The EPA’s CSAPR Update Rule issued on March 15, 2021, to revise the 2016 CSAPR Update does not apply to the state of Minnesota and is therefore not currently projected to affect Minnesota Power’s CSAPR compliance. The State of Minnesota has not been identified in litigation as a culpable upwind emission source to downwind states, and previous EPA air quality modeling has demonstrated that Minnesota is not a significant contributor to downwind air quality attainment challenges. Minnesota Power will continue to monitor ongoing CSAPR rulemakings and compliance implementation. X 2 National Ambient Air Quality Standards (NAAQS). The EPA is required to review the NAAQS every five years. If the EPA determines that a state’s air quality is not in compliance with the NAAQS, the state is required to adopt plans describing how it will reduce emissions to attain the NAAQS. Minnesota Power actively monitors NAAQS developments and compliance costs for existing standards or proposed NAAQS revisions are not currently expected to be material. The EPA is currently reviewing the secondary NAAQS for NOx and SO , as well as particulate matter. On June 10, 2021, the EPA announced it will reconsider the December 2020 final rule retaining the 2012 particulate matter NAAQS annual standard, with a proposed rulemaking anticipated in late 2022 and final action expected in early 2023. The EPA also stated it would complete reconsideration of the December 2020 Ozone NAAQS by the end of 2023. 2 ALLETE, Inc. 2021 Form 10-K 99 NOTE 8. COMMITMENTS, GUARANTEES AND CONTINGENCIES (Continued) Environmental Matters (Continued) Climate Change. The scientific community generally accepts that emissions of GHG are linked to global climate change which creates physical and financial risks. Physical risks could include, but are not limited to: increased or decreased precipitation and water levels in lakes and rivers; increased or other changes in temperatures; and changes in the intensity and frequency of extreme weather events. These all have the potential to affect the Company’s business and operations. We are addressing climate change by taking the following steps that also ensure reliable and environmentally compliant generation resources to meet our customers’ requirements: Expanding renewable power supply for both our operations and the operations of others; Providing energy conservation initiatives for our customers and engaging in other demand side management efforts; Improving efficiency of our generating facilities; Supporting research of technologies to reduce carbon emissions from generating facilities and carbon sequestration efforts; Evaluating and developing less carbon intensive future generating assets such as efficient and flexible natural gas‑fired generating facilities; • • • • • • Managing vegetation on right-of-way corridors to reduce potential wildfire or storm damage risks; and • Practicing sound forestry management in our service territories to create landscapes more resilient to disruption from climate-related changes, including planting and managing long-lived conifer species. EPA Regulation of GHG Emissions. In 2019, the EPA finalized several separate rulemakings regarding regulating carbon emissions from electric utility generating units. These rulemakings included repealing the Clean Power Plan (CPP) and adopting the Affordable Clean Energy Rule under Section 111(d) of the Clean Air Act (CAA) to regulate CO emissions at existing coal-fired power plants. The CPP was first announced as a proposed rule under Section 111(d) of the CAA for existing power plants entitled “Carbon Pollution Emission Guidelines for Existing Stationary Sources: Electric Generating Units”. The Affordable Clean Energy Rule established emissions guidelines for states to use when developing plans to limit CO coal-fired power plants. The EPA also published regulations for the state implementation of the Affordable Clean Energy Rule and other Section 111(d) rules. Affected facilities for Minnesota Power included Boswell Units 3 and 4, and Taconite Harbor Units 1 and 2, which are currently economically idled. 2 2 On January 19, 2021, the D.C. Circuit issued an opinion vacating the Affordable Clean Energy Rule and remanded the Affordable Clean Energy Rule back to the EPA for further consideration, consistent with the D.C. Circuit’s finding that the EPA erred in interpreting the CAA, pending rehearing or appeal. Four petitions were subsequently granted for review by the U.S. Supreme Court on October 29, 2021, with a decision expected in mid-2022. The EPA also indicated that it intends to issue a proposed rule in mid-2022 and a final rule in mid-2023 with a new set of emission guidelines for states to follow in submitting state plans to establish and implement standards of performance for GHG emissions from existing fossil fuel-fired electric generating units. Minnesota Power will continue to monitor any related guidelines and rulemakings issued by the EPA or state regulatory authorities. On April 22, 2021, the Biden Administration announced a goal to reach 100 percent carbon pollution-free electricity by 2035 as part of the Nationally Determined Contributions pledge, which is part of an international effort to limit global warming. At this time, no specific regulatory pathway to achieve these reductions has been proposed. Minnesota Power will continue to monitor these developments. Minnesota had already initiated several measures consistent with those called for under the now repealed CPP and vacated Affordable Clean Energy Rule. Minnesota Power continues implementing its EnergyForward strategic plan that provides for significant emission reductions and diversifying its electricity generation mix to include more renewable and natural gas energy. We are unable to predict the GHG emission compliance costs we might incur as a result of a replacement for the Affordable Clean Energy Rule or other future laws, regulations or administrative policies; however, the costs could be material. Minnesota Power would seek recovery of additional costs through a rate proceeding. ALLETE, Inc. 2021 Form 10-K 100 NOTE 8. COMMITMENTS, GUARANTEES AND CONTINGENCIES (Continued) Environmental Matters (Continued) Additionally on January 13, 2021, the EPA issued a rulemaking to apply CO emission New Source Performance Standards (NSPS) to new, modified and 2 reconstructed fossil fuel-fired electric generating units under Section 111(b) of the CAA. In April 2021, the EPA requested and was allowed to voluntarily vacate and remand the Significant Contribution Finding determination criteria related to this NSPS. The EPA intends to issue a proposed rule in mid-2022 and a final rule by mid-2023. Minnesota Power is monitoring the NSPS final rule and any further Section 111(b) developments including their potential impact to the Company. The Company’s proposed combined-cycle natural gas-fired generating facility, NTEC, is expected to meet these NSPS requirements. Water. The Clean Water Act requires NPDES permits be obtained from the EPA (or, when delegated, from individual state pollution control agencies) for any wastewater discharged into navigable waters. We have obtained all necessary NPDES permits, including NPDES storm water permits for applicable facilities, to conduct our operations. Steam Electric Power Generating Effluent Limitations Guidelines. In 2015, the EPA issued revised federal effluent limitation guidelines (ELG) for steam electric power generating stations under the Clean Water Act. It set effluent limits and prescribed BACT for several wastewater streams, including flue gas desulphurization (FGD) water, bottom ash transport water and coal combustion landfill leachate. In 2017, the EPA announced a two-year postponement of the ELG compliance date of November 1, 2018, to November 1, 2020, while the agency reconsidered the bottom ash transport water and FGD wastewater provisions. On April 12, 2019, the U.S. Court of Appeals for the Fifth Circuit vacated and remanded back to the EPA portions of the ELG that allowed for continued discharge of legacy wastewater and leachate. On October 13, 2020, the EPA published a final ELG Rule allowing re-use of bottom ash transport water in FGD scrubber systems with limited discharges related to maintaining system water balance. The rule sets technology standards and numerical pollutant limits for discharges of bottom ash transport water and FGD wastewater. Compliance deadlines depend on subcategory, with compliance generally required as soon as possible, beginning after October 13, 2021, but no later than December 31, 2025, or December 31, 2028, in some specific cases. The rule also established new subcategories for retiring high-flow and low-utilization units, and established a voluntary incentives program for FGD wastewater. In accordance with the January 2021 Executive Order 13990, the EPA was mandated to conduct a review of actions and polices taken during the prior administration, including the 2020 ELG Rule. On September 14, 2021, the EPA published a notice of availability for preliminary effluent guidelines program plan. In the plan, the EPA confirmed the agency is initiating a rulemaking process to strengthen wastewater pollution limitations from FGD and bottom ash transport water discharges while the 2020 ELG Rule remains in effect. The EPA is expected to publish a proposed rule in the fall of 2022. The ELG's potential impact on Minnesota Power operations is primarily at Boswell. Boswell currently discharges bottom ash contact water through its NPDES permit, and also has a closed-loop FGD system that does not discharge to surface waters, but may do so in the future. With Boswell’s planned conversion to dry FGD handling and storage, ongoing FGD water generation will be reduced, and the majority of FGD waters will be legacy waters to be dewatered from existing impoundments. Re-use and onsite consumption for the majority of FGD waters is planned at Boswell. Under the new ELG rule, most bottom ash transport water discharge to surface waters must cease no later than December 31, 2025, except for small discharges needed to retain water balance. The majority of bottom ash transport water will either need to be re-used in a closed-loop process or routed to a FGD scrubber. At Boswell, the bottom ash handling systems are planned to be converted to a dry process, which will eliminate the discharge of bottom ash transport water. The EPA’s additional reconsideration of legacy wastewater discharge requirements has the potential to reduce timelines for dewatering Boswell’s existing ponds. The EPA has withdrawn its separate action regarding the 2015 leachate and legacy wastewater ELGs and intends to consolidate that reconsideration with the 2020 bottom ash transport water and FGD ELG reconsideration. A proposed rule is expected in late 2022. ALLETE, Inc. 2021 Form 10-K 101 NOTE 8. COMMITMENTS, GUARANTEES AND CONTINGENCIES (Continued) Environmental Matters (Continued) At this time, we estimate that the planned dry conversion of bottom ash handling and storage at Boswell in response to the CCR revisions requiring closure of clay-lined impoundments, as well as other water re-use practices, will reduce or eliminate the need for additional significant compliance costs for ELG bottom ash water and FGD requirements. Compliance costs we might incur related to other ELG waste streams (e.g., legacy leachate) or other potential future water discharge regulations cannot be estimated; however, the costs could be material, including costs associated with wastewater treatment and re- use. Minnesota Power would seek recovery of additional costs through a rate proceeding. Permitted Water Discharges – Sulfate. In 2017, the MPCA released a draft water quality standard in an attempt to update Minnesota’s existing 10 mg/L sulfate limit for waters used for the production of wild rice with the proposed rulemaking heard before an administrative law judge (ALJ). In 2018, the ALJ rejected significant portions of the proposed rulemaking and the MPCA subsequently withdrew the rulemaking. The existing 10 mg/L limit remains in place, but the MPCA is currently prohibited under state law from listing wild rice waters as impaired or requiring sulfate reduction technology. In April 2021, the MPCA’s proposed list of impaired waters submitted pursuant to the Clean Water Act was partially rejected by the EPA due to the absence of wild rice waters listed for sulfate impairment. The EPA subsequently proposed a list of 30 wild rice waters in a separate listing process on April 29, 2021, followed by a list of three additional wild rice waters proposed separately on September 1, 2021. A final impaired waters listing is expected to follow, which could subsequently be used to set sulfate limits in discharge permits for power generation facilities and municipal and industrial customers, including paper and pulp facilities, and mining operations. At this time we are unable to determine the specific impacts these developments may have on Minnesota Power operations, if any. Minnesota Power would seek recovery of additional costs through a rate proceeding. Solid and Hazardous Waste. The Resource Conservation and Recovery Act of 1976 regulates the management and disposal of solid and hazardous wastes. We are required to notify the EPA of hazardous waste activity and, consequently, routinely submit reports to the EPA. Coal Ash Management Facilities. Minnesota Power produces the majority of its coal ash at Boswell, with small amounts of ash generated at Hibbard Renewable Energy Center. Ash storage and disposal methods include storing ash in clay-lined onsite impoundments (ash ponds), disposing of dry ash in a lined dry ash landfill, applying ash to land as an approved beneficial use, and trucking ash to state permitted landfills. Coal Combustion Residuals from Electric Utilities (CCR). In 2015, the EPA published the final rule regulating CCR as nonhazardous waste under Subtitle D of the Resource Conservation and Recovery Act (RCRA) in the Federal Register. The rule includes additional requirements for new landfill and impoundment construction as well as closure activities related to certain existing impoundments. Costs of compliance for Boswell and Laskin are expected to be incurred primarily over the next 15 years and be between approximately $65 million and $120 million. Compliance costs for CCR at Taconite Harbor are not expected to be material. Minnesota Power would seek recovery of additional costs through a rate proceeding. Minnesota Power continues to work on minimizing costs through evaluation of beneficial re-use and recycling of CCR and CCR-related waters. In 2017, the EPA announced its intention to formally reconsider the CCR rule under Subtitle D of the RCRA. In March 2018, the EPA published the first phase of the proposed rule revisions in the Federal Register. In 2018, the EPA finalized revisions to elements of the CCR rule, including extending certain deadlines by two years, the establishment of alternative groundwater protection standards for certain constituents and the potential for risk-based management options at facilities based on site characteristics. In 2018, a U.S. District Court for the District of Columbia decision vacated specific provisions of the CCR rule. The court decision resulted in a change to the status of three existing clay-lined impoundments at Boswell that must now be considered unlined. The EPA proposed additional rule revisions in 2019 to address outstanding issues from litigation and closure timelines for unlined impoundments, respectively. The first of these rules, CCR Part A Rule, was finalized in September 2020. The Part A Rule revision requires unlined impoundments to cease disposal of waste as soon as technically feasible but no later than April 11, 2021. This deadline has continued to toll as the EPA did not make any variance application determinations by that date. Minnesota Power sought EPA approval to extend the closure date for the two active Boswell impoundments in November 2020 through a variance application, and continues to operate the impoundments pending a final determination by the EPA. On January 11, 2022, the EPA issued a number of Part A and Part B variance application completeness determinations. The Boswell application was deemed complete; an approval or denial of the application is expected in mid-2022. ALLETE, Inc. 2021 Form 10-K 102 NOTE 8. COMMITMENTS, GUARANTEES AND CONTINGENCIES (Continued) Environmental Matters (Continued) Additionally, the EPA released a proposed Part B rulemaking in 2020 that addressed options for beneficial reuse of CCR materials, alternative liner demonstrations, and other CCR regulatory revisions. Portions of the Part B Rule addressing alternative liner equivalency standards were finalized in November 2020. According to the EPA’s regulatory agenda, finalization of the remainder of the proposed Part B Rule is expected in late 2022. Expected compliance costs at Boswell due to the court decision and subsequent rule revisions are reflected in our estimate of compliance costs for the CCR rule noted previously. Minnesota Power would seek recovery of additional costs through a rate proceeding. Other Environmental Matters Manufactured Gas Plant Site. We are reviewing and addressing environmental conditions at a former manufactured gas plant site located in Superior, Wisconsin, and formerly operated by SWL&P. SWL&P has been working with the Wisconsin Department of Natural Resources (WDNR) in determining the extent and location of contamination at the site and surrounding properties. As of December 31, 2021, we have recorded a liability of approximately $18 million for remediation costs at this site after further refining the scope of work and cost estimates as well as incorporating detailed design components specific to the site in 2021 (approximately $7 million as of December 31, 2020); however, SWL&P continues to work with the WDNR on the extent of contamination which may result in additional remediation costs being identified. SWL&P has also recorded an associated regulatory asset as we expect recovery of these remediation costs to be allowed by the PSCW. Remediation costs are expected to be incurred through 2023. Other Matters We have multiple credit facility agreements in place that provide the ability to issue standby letters of credit to satisfy our contractual security requirements across our businesses. As of December 31, 2021, we had $134.7 million of outstanding letters of credit issued, including those issued under our revolving credit facility. Regulated Operations. As of December 31, 2021, we had $10.9 million outstanding in standby letters of credit at our Regulated Operations which are pledged as security for MISO and state agency agreements as well as energy facilities under development. ALLETE Clean Energy. ALLETE Clean Energy’s wind energy facilities have PSAs in place for their output and expire in various years between 2022 and 2039. As of December 31, 2021, ALLETE Clean Energy has $87.4 million outstanding in standby letters of credit, the majority of which are pledged as security under these PSAs and PSAs for wind energy facilities under development. Corporate and Other. BNI Energy. As of December 31, 2021, BNI Energy had surety bonds outstanding of $71.2 million related to the reclamation liability for closing costs associated with its mine and mine facilities. Although its coal supply agreements obligate the customers to provide for the closing costs, additional assurance is required by federal and state regulations. BNI Energy’s total reclamation liability is currently estimated at $70.7 million. BNI Energy does not believe it is likely that any of these outstanding surety bonds will be drawn upon. Investment in Nobles 2. Nobles 2 wind energy facility requires standby letters of credit as security for certain contractual obligations. As of December 31, 2021, ALLETE South Wind has $12.5 million outstanding in standby letters of credit, related to our portion of the security requirements relative to our ownership in Nobles 2. South Shore Energy. As of December 31, 2021, South Shore Energy had $23.9 million outstanding in standby letters of credit pledged as security in connection with the development of NTEC. South Shore Energy does not believe it is likely that any of these outstanding letters of credit will be drawn upon. ALLETE Properties. As of December 31, 2021, ALLETE Properties had surety bonds outstanding and letters of credit to governmental entities totaling $2.0 million primarily related to development and maintenance obligations for various projects. The estimated cost of the remaining development work is $1.0 million. ALLETE Properties does not believe it is likely that any of these outstanding surety bonds or letters of credit will be drawn upon. ALLETE, Inc. 2021 Form 10-K 103 NOTE 8. COMMITMENTS, GUARANTEES AND CONTINGENCIES (Continued) Other Matters (Continued Community Development District Obligations. In 2005, the Town Center District issued $26.4 million of tax-exempt, 6.0 percent capital improvement revenue bonds. The capital improvement revenue bonds are payable over 31 years (by May 1, 2036) and are secured by special assessments on the benefited land. To the extent that ALLETE Properties still owns land at the time of the assessment, it will incur the cost of its portion of these assessments, based upon its ownership of benefited property. As of December 31, 2021, we owned 30 percent of the assessable land in the Town Center District (48 percent as of December 31, 2020). As of December 31, 2021, ownership levels, our annual assessments related to capital improvement and special assessment bonds for the ALLETE Properties project within the district is approximately $1.8 million. As we sell property at this project, the obligation to pay special assessments will pass to the new landowners. In accordance with accounting guidance, these bonds are not reflected as debt on our Consolidated Balance Sheet. Legal Proceedings. We are involved in litigation arising in the normal course of business. Also in the normal course of business, we are involved in tax, regulatory and other governmental audits, inspections, investigations and other proceedings that involve state and federal taxes, safety, and compliance with regulations, rate base and cost of service issues, among other things. We do not expect the outcome of these matters to have a material effect on our financial position, results of operations or cash flows. Minnesota Power has been named in a lawsuit where a contractor performing work at one of its facilities experienced an injury and subsequently filed a lawsuit seeking compensatory damages. Litigation related to this injury is ongoing. At this time, a loss is considered reasonably possible; however, we do not deem it probable, and we are unable to estimate a loss or range of loss related to the litigation at this time. NOTE 9.

The unrecognized tax benefit balance includes permanent tax positions which, if recognized would affect the annual effective income tax rate. In addition, the unrecognized tax benefit balance includes temporary tax positions for which the ultimate deductibility is highly certain but for which there is uncertainty about the timing of such deductibility. A change in the period of deductibility would not affect the effective tax rate but would accelerate the payment of cash to the taxing authority to an earlier period. The gross unrecognized tax benefits as of December 31, 2021, included $0.6 million of net unrecognized tax benefits which, if recognized, would affect the annual effective income tax rate. As of December 31, 2021, we had no accrued interest (none as of December 31, 2020, and 2019) related to unrecognized tax benefits included on the Consolidated Balance Sheet due to our NOL carryforwards. We classify interest related to unrecognized tax benefits as interest expense and tax-related penalties in operating expenses on the Consolidated Statement of Income. Interest expense related to unrecognized tax benefits on the Consolidated Statement of Income was immaterial in 2021, 2020 and 2019. There were no penalties recognized in 2021, 2020 or 2019. The unrecognized tax benefit amounts have been presented as reductions to the tax benefits associated with NOL and tax credit carryforwards on the Consolidated Balance Sheet. No material changes to unrecognized tax benefits are expected during the next 12 months. ALLETE and its subsidiaries file a consolidated federal income tax return as well as combined and separate state income tax returns in various jurisdictions. ALLETE has no open federal or state audits, and is no longer subject to federal examination for years before 2018 or state examination for years before 2017. ALLETE, Inc. 2021 Form 10-K 107 NOTE 11. PENSION AND OTHER POSTRETIREMENT BENEFIT PLANS We have noncontributory union, non-union and combined retiree defined benefit pension plans covering eligible employees. The combined retiree defined benefit pension plan was created in 2016, to include all union and non-union retirees from the existing plans as of January 1, 2016. The plans provide defined benefits based on years of service and final average pay. We contributed $10.3 million in cash to the plans in 2021 ($10.7 million in 2020; $10.4 million in 2019). We also have a defined contribution RSOP covering substantially all employees. The 2021 plan year employer contributions, which are made through the employee stock ownership plan portion of the RSOP, totaled $11.5 million ($11.2 million for the 2020 plan year; $10.8 million for the 2019 plan year). (See Note 9. Common Stock and Earnings Per Share and Note 12. Employee Stock and Incentive Plans.) The non-union defined benefit pension plan was frozen in 2018, and does not allow further crediting of service or earnings to the plan. Further, it is closed to new participants. The Minnesota Power union defined benefit pension plan is also closed to new participants, and the SWL&P union defined benefit pension plan was closed to new participants effective February 1, 2022. We have postretirement health care and life insurance plans covering eligible employees. In 2010, the postretirement health care plan was closed to employees hired after January 31, 2011, and the eligibility requirements were amended. In 2014, the postretirement life plan was amended to close the plan to non-union employees retiring after December 31, 2015, and in 2018, the postretirement life plan was amended to limit the benefit level for union employees retiring after December 31, 2018. The postretirement health and life plans are contributory with participant contributions adjusted annually. Postretirement health and life benefits are funded through a combination of Voluntary Employee Benefit Association trusts (VEBAs), established under section 501(c)(9) of the Internal Revenue Code, and irrevocable grantor trusts. In 2021, no contributions were made to the VEBAs (none in 2020; none in 2019) and no contributions were made to the grantor trusts (none in 2020; none in 2019). Management considers various factors when making funding decisions such as regulatory requirements, actuarially determined minimum contribution requirements and contributions required to avoid benefit restrictions for the pension plans. Contributions are based on estimates and assumptions which are subject to change. We do not expect to make any contributions to the defined benefit pension plans in 2022, and we do not expect to make any contributions to the defined benefit postretirement health and life plans in 2022. Accounting for defined benefit pension and other postretirement benefit plans requires that employers recognize on a prospective basis the funded status of their defined benefit pension and other postretirement plans on their balance sheet and recognize as a component of other comprehensive income, net of tax, the gains or losses and prior service costs or credits that arise during the period but are not recognized as components of net periodic benefit cost. The defined benefit pension and postretirement health and life benefit expense (credit) recognized annually by our regulated utilities are expected to be recovered (refunded) through rates filed with our regulatory jurisdictions. As a result, these amounts that are required to otherwise be recognized in accumulated other comprehensive income have been recognized as a long-term regulatory asset (regulatory liability) on the Consolidated Balance Sheet, in accordance with the accounting standards for the effect of certain types of regulation applicable to our Regulated Operations. The defined benefit pension and postretirement health and life benefit expense (credits) associated with our other operations are recognized in accumulated other comprehensive income.

In establishing the expected long-term rate of return on plan assets, we determine the long-term historical performance of each asset class, adjust these for current economic conditions, and utilizing the target allocation of our plan assets, forecast the expected long-term rate of return. The discount rate is computed using a bond matching study which utilizes a portfolio of high quality bonds that produce cash flows similar to the projected costs of our pension and other postretirement plans. The Company utilizes actuarial assumptions about mortality to calculate the pension and postretirement health and life benefit obligations. The mortality assumptions used to calculate our pension and other postretirement benefit obligations as of December 31, 2021, considered a modified PRI-2012 mortality table and MP-2021 mortality projection scale.

The defined benefit pension plans have adopted a dynamic asset allocation strategy (glide path) that increases the invested allocation to fixed income assets as the funding level of the plan increases to better match the sensitivity of the plan’s assets and liabilities to changes in interest rates. This is expected to reduce the volatility of reported pension plan expenses. The postretirement health and life plans’ assets are diversified to achieve strong returns within managed risk. Equity securities are diversified among domestic companies with large, mid and small market capitalizations, as well as investments in international companies. The majority of debt securities are made up of investment grade bonds.

Fair Value Pension Postretirement Health and Life (a) 49 % 49 % 1 % 1 % 100 % 60 % 37 % — 3 % 100 % Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). We utilize market data or assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market corroborated, or generally unobservable. We primarily apply the market approach for recurring fair value measurements and endeavor to utilize the best available information. Accordingly, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. These inputs, which are used to measure fair value, are prioritized through the fair value hierarchy. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement).

The federal subsidy is reflected in the premiums charged to us by the insurance company. NOTE 12. EMPLOYEE STOCK AND INCENTIVE PLANS Employee Stock Ownership Plan. We sponsor an ESOP within the RSOP. Eligible employees may contribute to the RSOP plan as of their date of hire. The dividends received by the ESOP are distributed to participants. Dividends on allocated ESOP shares are recorded as a reduction of retained earnings. ESOP employer allocations are funded with contributions paid in either cash or the issuance of ALLETE common stock at the Company’s discretion. We record compensation expense equal to the cash or current market price of stock contributed. ESOP compensation expense was $11.5 million in 2021 ($11.2 million in 2020; $10.8 million in 2019). According to the accounting standards for stock compensation, unallocated shares of ALLETE common stock held and purchased by the ESOP were treated as unearned ESOP shares and not considered outstanding for earnings per share computations. All ESOP shares have been allocated to participants as of December 31, 2021, 2020 and 2019. Stock-Based Compensation. Stock Incentive Plan. Under our Executive Long-Term Incentive Compensation Plan (Executive Plan), share-based awards may be issued to key employees through a broad range of methods, including non-qualified and incentive stock options, performance shares, performance units, restricted stock, restricted stock units, stock appreciation rights and other awards. There are 0.7 million shares of ALLETE common stock reserved for issuance under the Executive Plan, of which 0.7 million of these shares remain available for issuance as of December 31, 2021. ALLETE, Inc. 2021 Form 10-K 117 NOTE 12. EMPLOYEE STOCK AND INCENTIVE PLANS (Continued) Stock-Based Compensation (Continued) The following types of share-based awards were outstanding in 2021, 2020 or 2019: Performance Shares. Under the performance share awards, the number of shares earned is contingent upon attaining specific market and performance goals over a three-year performance period. Market goals are measured by total shareholder return relative to a group of peer companies while performance goals are measured by earnings per share growth. In the case of qualified retirement, death, or disability during a performance period, a pro rata portion of the award will be earned at the conclusion of the performance period based on the market goals achieved. In the case of termination of employment for any reason other than qualified retirement, death, or disability, no award will be earned. If there is a change in control, a pro rata portion of the award will be paid based on the greater of actual performance up to the date of the change in control or target performance. The fair value of these awards incorporates the probability of meeting the total shareholder return goals. Compensation cost is recognized over the three-year performance period based on our estimate of the number of shares which will be earned by the award recipients. Restricted Stock Units. Under the restricted stock unit awards, shares for participants eligible for retirement vest monthly over a three-year period. For participants not eligible for retirement, shares vest at the end of the three-year period. In the case of qualified retirement, death or disability, a pro rata portion of the award will be earned. In the case of termination of employment for any reason other than qualified retirement, death or disability, no award will be earned. If there is a change in control, a pro rata portion of the award will be earned. The fair value of these awards is equal to the grant date fair value. Compensation cost is recognized over the three-year vesting period based on our estimate of the number of shares which will be earned by the award recipients. Employee Stock Purchase Plan (ESPP). Under our ESPP, eligible employees may purchase ALLETE common stock at a 5 percent discount from the market price; we are not required to apply fair value accounting to these awards as the discount is not greater than 5 percent. RSOP. The RSOP is a contributory defined contribution plan subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended, and qualifies as an employee stock ownership plan and profit sharing plan. The RSOP provides eligible employees an opportunity to save for retirement. The following share-based compensation expense amounts were recognized in our Consolidated Statement of Income for the periods presented. Share-Based Compensation Expense Year Ended December 31 Millions Performance Shares Restricted Stock Units Total Share-Based Compensation Expense Income Tax Benefit 2021 $2.0 1.0 $3.0 $0.9 2020 $2.2 0.9 $3.1 $0.9 2019 $2.3 0.8 $3.1 $0.9 There were no capitalized share-based compensation costs during the years ended December 31, 2021, 2020 or 2019. As of December 31, 2021, the total unrecognized compensation cost for the performance share awards and restricted stock units not yet recognized in our Consolidated Statement of Income was $1.8 million and $0.9 million, respectively. These amounts are expected to be recognized over a weighted-average period of 1.7 years and 1.6 years, respectively. ALLETE, Inc. 2021 Form 10-K 118 NOTE 12.

(2) the sum of: (a) the alternate benchmark rate that has been selected by the Administrative Agent and the Borrower as the replacement for the then-current Benchmark for the applicable Corresponding Tenor giving due consideration to (i) any selection or recommendation of a replacement benchmark rate or the mechanism for determining such a rate by the Relevant Governmental Body or (ii) any evolving or then-prevailing market convention for determining a benchmark rate as a replacement for the then-current Benchmark for dollar-denominated syndicated 744315352 11074672 3 ALLETE CREDIT AGREEMENT credit facilities at such time in the United States and (b) the related Benchmark Replacement Adjustment. If the Benchmark Replacement as determined pursuant to clause (1) or (2) above would be less than the Floor, the Benchmark Replacement will be deemed to be the Floor for the purposes of this Agreement and the other Loan Documents. “Benchmark Replacement Adjustment” means, with respect to any replacement of the then-current Benchmark with an Unadjusted Benchmark Replacement for any applicable Interest Period and Available Tenor for any setting of such Unadjusted Benchmark Replacement, the spread adjustment, or method for calculating or determining such spread adjustment, (which may be a positive or negative value or zero) that has been selected by the Administrative Agent and the Borrower for the applicable Corresponding Tenor giving due consideration to (i) any selection or recommendation of a spread adjustment, or method for calculating or determining such spread adjustment, for the replacement of such Benchmark with the applicable Unadjusted Benchmark Replacement by the Relevant Governmental Body on the applicable Benchmark Replacement Date and/or (ii) any evolving or then-prevailing market convention for determining a spread adjustment, or method for calculating or determining such spread adjustment, for the replacement of such Benchmark with the applicable Unadjusted Benchmark Replacement for dollar-denominated syndicated credit facilities at such time. “Benchmark Replacement Conforming Changes” means, with respect to any Benchmark Replacement and/or any Term Benchmark Loan, any technical, administrative or operational changes (including changes to the definition of “Alternate Base Rate,” the definition of “Business Day,” the definition of “U.S. Government Securities Business Day,” the definition of “Interest Period,” timing and frequency of determining rates and making payments of interest, timing of Credit Requests or prepayment, conversion or continuation notices, length of lookback periods, the applicability of breakage provisions, and other technical, administrative or operational matters) that the Administrative Agent decides may be appropriate to reflect the adoption and implementation of such Benchmark and to permit the administration thereof by the Administrative Agent in a manner substantially consistent with market practice (or, if the Administrative Agent decides that adoption of any portion of such market practice is not administratively feasible or if the Administrative Agent determines that no market practice for the administration of such Benchmark exists, in such other manner of administration as the Administrative Agent decides is reasonably necessary in connection with the administration of this Agreement and the other Loan Documents). “Benchmark Replacement Date” means, with respect to any Benchmark, the earliest to occur of the following events with respect to such then-current Benchmark: (1) in the case of clause (1) or (2) of the definition of “Benchmark Transition Event,” the later of (a) the date of the public statement or publication of information referenced therein and (b) the date on which the administrator of such Benchmark (or the published component used in the calculation thereof) permanently or indefinitely ceases to provide all Available Tenors of such Benchmark (or such component thereof); or (2) in the case of clause (3) of the definition of “Benchmark Transition Event,” the first date on which such Benchmark (or the published component used in the calculation thereof) has been determined and announced by the regulatory supervisor for the administrator of such Benchmark (or such component thereof) to be no longer representative; provided, that such non- representativeness will be determined by reference to the most recent statement or publication referenced in such clause (3) and even if any Available Tenor of such Benchmark (or such component thereof) continues to be provided on such date.

Each such Credit Request shall be irrevocable (except as otherwise provided in Section 3.4) and shall specify the following information in compliance with Section 2.2: (i) (ii) the aggregate amount of the requested Borrowing; the date of such Borrowing, which shall be a Business Day; (iii) whether such Borrowing is to be an ABR Borrowing or a Term Benchmark Borrowing; 744315352 11074672 23 ALLETE CREDIT AGREEMENT (iv) in the case of a Term Benchmark Borrowing, the initial Interest Period to be applicable thereto, which shall be a period contemplated by the definition of the term “Interest Period”; and (v) the location and number of the Borrower’s account to which funds are to be disbursed, which shall comply with the requirements of Section 2.4. (b) If no election as to the Type of Borrowing is specified, then the requested Borrowing shall be an ABR Borrowing. If no Interest Period is specified with respect to any requested Term Benchmark Borrowing, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration. Promptly following receipt of a Credit Request in accordance with this Section, the Administrative Agent shall advise each Lender of the details thereof and of the amount of such Lender’s Loan to be made as part of the requested Borrowing. Section 1.4. Funding of Borrowings. (a) Each Lender shall make each Loan to be made by it hereunder on the proposed date thereof by wire transfer of immediately available funds by 2:00 p.m. to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders. Subject to Section 5.2, the Administrative Agent will make such Loans available to the Borrower by promptly crediting or otherwise transferring the amounts so received, in like funds, to an account of the Borrower designated by the Borrower in the applicable Credit Request, provided that ABR Loans made to finance the reimbursement of an LC Disbursement as provided in Section 2.9(e) shall be remitted by the Administrative Agent to the applicable Issuing Bank. (b) Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Borrowing (or purchase of participations pursuant to Section 2.9(e)) that such Lender will not make available to the Administrative Agent such Lender’s share of such Borrowing (or the amount of its participation), the Administrative Agent may assume that such Lender has made such share available on such date in accordance with Section 2.4(a) or Section 2.9(e) and may, in reliance upon such assumption, make available to the Borrower or the applicable Issuing Bank, as applicable, a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the Administrative Agent, then the applicable Lender and the Borrower (and, if applicable, the applicable Issuing Bank) severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower or such Issuing Bank, as applicable, to but excluding the date of payment to the Administrative Agent, at (i) in the case of such Lender or an Issuing Bank, the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation or (ii) in the case of the Borrower, the interest rate that would be otherwise applicable to such Borrowing (or such participating interest). Any payment by the Borrower or an Issuing Bank, however, shall be without prejudice to its rights against the applicable Lender. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s Loan included in such Borrowing (or participation in the applicable LC Disbursement). Section 1.5. Termination, Reduction and Increase of Commitments. (a) Unless previously terminated, the Commitments shall terminate on the Maturity Date. For the avoidance of doubt, the Commitment of the Second Amendment Declining Lender shall terminate on the Initial Maturity Date and the total Commitments hereunder shall be reduced by the Commitment of the Second Amendment Declining Lender so terminated on such date except to the extent that the Borrower has required the Second Amendment Declining Lender to assign its rights under this Agreement to one or more Eligible Assignees that have agreed to extend their respective Commitments to terminate on the Maturity Date in accordance with Section 2.8. 744315352 11074672 24 ALLETE CREDIT AGREEMENT (b) The Borrower may at any time terminate, or from time to time reduce, the Commitments, provided that the Borrower shall not terminate or reduce the Commitments if, after giving effect to any concurrent prepayment or repayment of the Loans in accordance with Section 2.7, the sum of the Credit Exposures would exceed the total Commitments and each such reduction of the Commitments shall be in the amount of $5,000,000 or a higher integral multiple of $1,000,000. (c) The Borrower shall notify the Administrative Agent of any election to terminate or reduce the Commitments under paragraph (b) of this Section at least three Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly following receipt of any notice, the Administrative Agent shall advise the Lenders of the contents thereof. Each notice delivered by the Borrower pursuant to this Section shall be irrevocable, provided that a notice of termination of the Commitments delivered by the Borrower may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by the Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied. Each reduction, and any termination, of the Commitments shall be permanent and each reduction of the Commitments shall be made ratably among the Lenders in accordance with their respective Commitments. (d) The Borrower may at any time and from time to time prior to the Maturity Date, at its sole cost, expense and effort, request any one or more of the Lenders to increase its Commitment (the decision to increase the Commitment of a Lender to be within the sole and absolute discretion of such Lender), or any other Person reasonably satisfactory to the Administrative Agent and the Issuing Banks to provide a new Commitment, by submitting to the Administrative Agent and the Issuing Banks an Increase Supplement duly executed by the Borrower and each such Lender or other Person, as the case may be, together with such other documentation and deliveries as the Administrative Agent shall reasonably require (which may include copies of resolutions authorizing such increase and/or opinion of counsel). If such Increase Supplement is in all respects reasonably satisfactory to the Administrative Agent and the Issuing Banks, the Administrative Agent shall execute such Increase Supplement and the Administrative Agent shall deliver a copy thereof to the Borrower and each such Lender or other Person, as the case may be. Upon execution and delivery of such Increase Supplement by the Administrative Agent and the Issuing Banks, (i) in the case of each such Lender (an “Increasing Lender”), its Commitment shall be increased to the amount set forth in such Increase Supplement, (ii) in the case of each such other Person (a “New Lender”), such New Lender shall become a party hereto and have the rights and obligations of a Lender under the Loan Documents and its Commitment shall be as set forth in such Increase Supplement; provided that: (A) immediately after giving effect thereto, the sum of all increases (other than any increase in any Lender’s Commitment in order to replace another Lender pursuant to Section 3.8(b)) in the aggregate Commitments made pursuant to this Section 2.5(d) shall not exceed the sum of (x) $150,000,000 plus (y) the amount of the Commitment of each Lender that becomes a Defaulting Lender; (B) each such increase of the aggregate Commitments shall be in an amount not less than $10,000,000 or a higher integral multiple of $5,000,000; (C) if Loans would be outstanding immediately after giving effect to any such increase, then simultaneously with such increase (1) each such Increasing Lender, each New Lender and each other Lender shall be deemed to have entered into an Assignment and Assumption, pursuant to which each such other Lender shall have assigned to each such Increasing Lender and each such New Lender a portion of its Commitment, Loans and LC Exposure necessary to reflect proportionately the Commitments as adjusted in accordance with this paragraph (d), and (2) in connection with such assignment, each such Increasing Lender and each such New Lender shall pay to the Administrative Agent, for the account of each such other Lender, such amount as shall be necessary to reflect the assignment to it of Loans, and in connection with such master assignment each such other Lender may treat the 744315352 11074672 25 ALLETE CREDIT AGREEMENT assignment of Term Benchmark Borrowings as a prepayment of such Term Benchmark Borrowings for purposes of Section 3.6; (D) each such other Person shall have delivered to the Administrative Agent and the Borrower all forms, if any, that are required to be delivered by such other Person pursuant to Section 3.7; and (E) the Borrower shall have delivered to the Administrative Agent sufficient copies for each Lender of a certificate of a Financial Officer demonstrating pro forma compliance with the terms of this Agreement through the Maturity Date and the Administrative Agent shall have received such certificates and other items as it shall reasonably request in connection with such increase. Section 1.6. Repayment of Loans; Evidence of Debt. (a) The Borrower hereby unconditionally promises to pay to the Administrative Agent for the account of each Lender the then unpaid principal amount of each Loan on the Maturity Date. For the avoidance of doubt, on the Initial Maturity Date, the Borrower shall make prepayments of the outstanding Loans and provide such cash collateral (or make such other arrangements satisfactory to the applicable Issuing Bank) with respect to the outstanding Letters of Credit as shall be required such that, after giving effect to the termination of the Commitment of the Second Amendment Declining Lender pursuant to Section 2.5(a), the aggregate Credit Exposure less the face amount of any Letter of Credit supported by any such cash collateral (or other satisfactory arrangements) so provided does not exceed the aggregate amount of Commitments after giving effect to such Commitment termination. Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the debt of the Borrower to such Lender resulting from each Loan made by such Lender, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder. (b) (c) The Administrative Agent shall maintain accounts in which it shall record the amount of each Loan made hereunder, the Type thereof and the Interest Period, if any, applicable thereto, the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and the amount of any sum received by the Administrative Agent hereunder for the account of the Lenders and each Lender’s share thereof. (d) The entries made in the accounts maintained pursuant to paragraph (b) or (c) of this Section shall be prima facie evidence of the existence and amounts of the obligations recorded therein, provided that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Loans in accordance with the terms of this Agreement. (e) Any Lender may request that its Loans be evidenced by a Note. In such event, the Borrower shall prepare, execute and deliver to such Lender a Note payable to the order of such Lender. Thereafter, the Loans evidenced by such Note and interest thereon shall at all times (including after any assignment pursuant to Section 10.4) be represented by a Note payable to the order of the payee named therein or any Eligible Assignee pursuant to Section 10.4, except to the extent that any such Lender or Eligible Assignee subsequently returns any such Note for cancellation and requests that such Loans once again be evidenced as described in paragraphs (b) and (c) above. Section 1.7. Prepayment of Loans. Borrowing in whole or in part, subject to the requirements of this Section. (a) Voluntary Prepayments. The Borrower shall have the right at any time and from time to time to prepay any 744315352 11074672 26 ALLETE CREDIT AGREEMENT (b) Prepayments Resulting from the Reduction of the Total Commitments. In the event of any partial reduction or termination of the Commitments, then at or prior to the date of such reduction or termination, the Administrative Agent shall notify the Borrower and the Lenders of the sum of the Credit Exposures after giving effect thereto and if such sum would exceed the total Commitments after giving effect to such reduction or termination, then the Borrower shall, on the date of such reduction or termination, prepay Borrowings in an amount sufficient to eliminate such excess. (c) Notice of Prepayment; Application of Prepayments. The Borrower shall notify the Administrative Agent by telephone (confirmed by facsimile) of any prepayment hereunder, (i) in the case of a prepayment of a Term Benchmark Borrowing, not later than 11:30 a.m. three Business Days before the date of prepayment or (ii) in the case of prepayment of an ABR Borrowing, not later than 11:30 a.m. on the date of the prepayment. Each such notice shall be irrevocable and shall specify the prepayment date and the principal amount of each Borrowing or portion thereof to be prepaid, provided that, if a notice of prepayment is given in connection with a conditional notice of termination of the Commitments as contemplated by Section 2.5, then such notice of prepayment may be revoked if such notice of termination is revoked in accordance with Section 2.5. Promptly following receipt of any such notice relating to a Borrowing, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any Borrowing shall be in an integral multiple of $1,000,000 and not less than $5,000,000 (or, if the outstanding principal balance of the applicable Borrowing is less than such minimum amount, then such lesser outstanding principal balance); provided that if, as a result of any ABR Borrowing to reimburse an LC Disbursement pursuant to Section 2.9(e), the aggregate principal amount of all ABR Borrowings is not an integral multiple of $1,000,000, then any prepayment of ABR Borrowings shall be in an amount that will cause the aggregate principal amount of all ABR Borrowings to be an integral multiple of $1,000,000. Each prepayment of a Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing. Prepayments shall be accompanied by accrued interest to the extent required by Section 3.1 and, if applicable, shall be subject to the provisions of Section 3.6. Notwithstanding any provision of this Section 2.7(c) to the contrary, if any Lender becomes a Defaulting Lender, then the provisions of Section 2.11 shall apply for so long as such Lender is a Defaulting Lender. Section 1.8. Extension of Maturity Date. After November 23, 2021, the Borrower may, on one occasion during the term of this Agreement, request an extension of the Maturity Date for an additional one-year period by submitting a request for extension (an “Extension Request”) to the Administrative Agent (which shall promptly advise each Lender) not more than 75 days or less than 30 days prior to the effective date of the proposed extension (the “Extension Effective Date”). In response to such request, each Lender shall, not later than 20 days prior to the applicable Extension Effective Date, notify the Administrative Agent whether it is willing (in its sole and complete discretion) to extend the scheduled Maturity Date for an additional one-year period (and any Lender that fails to give such notice to the Administrative Agent shall be deemed to have elected not to extend the scheduled Maturity Date). The Administrative Agent will notify the Borrower of the Lenders’ decisions no later than 15 days prior to such Extension Effective Date. If Lenders holding more than 50% of the Commitments elect to extend the scheduled Maturity Date, then on such Extension Effective Date the Commitments of such Lenders shall be extended for an additional one-year period; provided that (i) no Default exists on such Extension Effective Date and (ii) all representations and warranties are true and correct on such Extension Effective Date, as though made as of such Extension Effective Date (or, if any such representation or warranty is expressly stated to have been made as of a specific date, as of such specific date). No Lender shall be required to consent to any Extension Request and any Lender that elects, or is deemed to have elected, not to extend the scheduled Maturity Date (a “Declining Lender”) will have its Commitment terminated on the then existing scheduled Maturity Date (without regard to any extension by other Lenders). The Borrower may, at its sole expense and effort, upon notice to any Declining Lender and the Administrative Agent, require any Declining Lender to assign and delegate its rights and obligations under this Agreement to an Eligible Assignee selected by the Borrower and willing to accept such assignment (in accordance with, and subject to, the restrictions and consents otherwise required for assignments generally). 744315352 11074672 27 ALLETE CREDIT AGREEMENT Section 1.9. Letters of Credit. (a) General. Subject to the terms and conditions set forth herein, the Borrower may request the issuance of Letters of Credit denominated in dollars as the applicant thereof for the support of its or its Subsidiaries’ obligations, in a form acceptable to the Administrative Agent and the applicable Issuing Bank, at any time and from time to time during the period from the Effective Date to the tenth Business Day preceding the last day of the Availability Period; provided that (i) the aggregate amount of the Credit Exposure of all Lenders shall not exceed the total Commitments and (ii) the aggregate amount of all LC Exposure shall not at any time exceed $100,000,000. In the event of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of any form of letter of credit application or other agreement submitted by the Borrower to, or entered into by the Borrower with, an Issuing Bank relating to any Letter of Credit, the terms and conditions of this Agreement shall control. (b) Notice of Issuance; Amendment; Renewal; Extension; Certain Conditions. To request the issuance of a Letter of Credit (or the amendment, renewal or extension of an outstanding Letter of Credit), the Borrower shall hand deliver or facsimile (or transmit by electronic communication, pursuant to arrangements for doing so approved by the applicable Issuing Bank) to the applicable Issuing Bank and the Administrative Agent (not later than three Business Days before the requested date of issuance, amendment, renewal or extension) a Credit Request requesting the issuance of a Letter of Credit, or identifying the Letter of Credit to be amended, renewed or extended, and specifying the date of issuance, amendment, renewal or extension (which shall be a Business Day), the date on which such Letter of Credit is to expire (which shall comply with paragraph (c) of this Section), the amount of such Letter of Credit, the name and address of the beneficiary thereof and such other information as shall be necessary to prepare, amend, renew or extend such Letter of Credit. If requested by an Issuing Bank, the Borrower also shall submit a letter of credit application on such Issuing Bank’s standard form in connection with any request for a Letter of Credit. A Letter of Credit shall be issued, amended, renewed or extended only if (and, upon issuance, amendment, renewal or extension of each Letter of Credit, the Borrower shall be deemed to represent and warrant that), after giving effect to such issuance, amendment, renewal or extension, (i) (x) the aggregate undrawn amount of all outstanding Letters of Credit issued by the Issuing Bank at such time plus (y) the aggregate amount of all LC Disbursements made by the Issuing Bank that have not yet been reimbursed by or on behalf of the Borrower at such time shall not exceed its Letter of Credit Commitment, (ii) the LC Exposure shall not exceed the total Letter of Credit Commitments, (iii) the total Credit Exposures shall not exceed the total Commitments. The Borrower may, at any time and from time to time, reduce the Letter of Credit Commitment of any Issuing Bank with the consent of such Issuing Bank; provided that the Borrower shall not reduce the Letter of Credit Commitment of any Issuing Bank if, after giving effect of such reduction, the conditions set forth in clauses (i) and (ii) above shall not be satisfied. (c) Expiration Date. Each Letter of Credit shall expire at or prior to the close of business on the earlier of (i) the date that is one year after the date of the issuance of such Letter of Credit (or, in the case of any renewal or extension thereof, one year after such renewal or extension), and (ii) the date that is ten Business Days prior to the Maturity Date, provided that any Letter of Credit may provide for the automatic renewal thereof for any period (unless the applicable Issuing Bank elects not to extend) so long as such period ends at least ten Business Days prior to the Maturity Date or if the Borrower shall have deposited cash collateral with the Administrative Agent to the extent required by Section 2.9(j) for such Letter of Credit, not later than the first anniversary of the Maturity Date. (d) Participations. By the issuance of a Letter of Credit (or an amendment to a Letter of Credit increasing the amount thereof) and without any further action on the part of the applicable Issuing Bank or the Lenders, such Issuing Bank hereby grants to each Lender and each Lender hereby acquires from such Issuing Bank, a participation in such Letter of Credit equal to such Lender’s Applicable Percentage of the aggregate amount available to be drawn under such Letter of Credit. In consideration and in furtherance of the foregoing, each such Lender hereby absolutely and unconditionally agrees to pay to the Administrative Agent, for the account of such Issuing Bank, such 744315352 11074672 28 ALLETE CREDIT AGREEMENT Lender’s Applicable Percentage of each LC Disbursement made by such Issuing Bank and not reimbursed by the Borrower on the date due as provided in paragraph (e) of this Section, or of any reimbursement payment required to be refunded to the Borrower for any reason. Each such Lender acknowledges and agrees that its obligation to acquire participations pursuant to this paragraph in respect of Letters of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including any amendment, renewal or extension of any Letter of Credit or the occurrence and continuance of a Default or reduction or termination of the Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever. (e) Reimbursement. If any Issuing Bank shall make an LC Disbursement in respect of a Letter of Credit, then such Issuing Bank shall promptly notify the Borrower of such LC Disbursement and the Borrower shall reimburse such LC Disbursement by paying to the Administrative Agent, for the account of such Issuing Bank, an amount equal to such LC Disbursement and any accrued interest thereon (collectively, the “Unreimbursed Amount”) by not later than (i) if the Borrower shall have received notice of such LC Disbursement prior to 11:00 a.m. on such date, 2:00 p.m. on such date, or (ii) otherwise, 2:00 p.m. on the Business Day immediately following the day that the Borrower receives such notice. If the Borrower fails to reimburse an Issuing Bank in full for an LC Disbursement prior to the time required pursuant to the preceding sentence, then such Issuing Bank may (and the Borrower authorizes such Issuing Bank to) request, on behalf of the Borrower by notice to the Administrative Agent (which shall promptly advise each Lender), that the Lenders fund an ABR Borrowing in an amount equal to the Unreimbursed Amount, without regard to the minimum and integral multiple requirements in Section 2.2(c), and each Lender shall make its Loan as part of such ABR Borrowing (by wire transfer of immediately available funds to the account most recently designated by the Administrative Agent for such purpose by notice to the Lenders) not later than (x) if such Lender shall have received notice of such Borrowing from the Administrative Agent prior to 12:00 noon on such date, 2:00 p.m. on such date or (y) otherwise, 2:00 p.m. on the Business Day immediately following the day that such Lender receives such notice; provided that if the conditions precedent to a Borrowing specified in Section 5.2 are not satisfied, then the request by the Issuing Bank shall be deemed to be a request for the funding of the Lenders’ participations in such Unreimbursed Amount and the amounts made available by the Lenders to the Administrative Agent as provided above shall constitute the Lenders’ funding of their respective participations in such Unreimbursed Amount. The Administrative Agent will make the proceeds of such Loans or participations, as applicable, available to the applicable Issuing Bank by promptly crediting or otherwise transferring the amounts so received, in like funds, to such Issuing Bank for the purpose of repaying in full the LC Disbursement and all accrued interest thereon. Any Lender that fails to make the proceeds of its Loan or its participation available to the Administrative Agent in accordance with the provisions of this Section 2.9(e) shall pay interest thereon, for the account of the applicable Issuing Bank, for each day from and including the date such amount is due to but excluding the date such amount is received by the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation. (f) Obligations Absolute. The Borrower’s obligations to reimburse LC Disbursements as provided in paragraph (e) of this Section shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever and irrespective of any lack of validity or enforceability of any Letter of Credit or any Loan Document, or any term or provision therein, any draft or other document presented under a Letter of Credit proving to be forged, fraudulent, insufficient or invalid in any respect or any statement therein being untrue or inaccurate in any respect, payment by any Issuing Bank under a Letter of Credit against presentation of a draft or other document that does not comply with the terms of such Letter of Credit, any amendment or waiver of or any consent to departure from all or any of the provisions of any Letter of Credit or any Loan Document, the existence of any claim, set-off, defense or other right that the Borrower, any other party guaranteeing, or otherwise obligated with, such Borrower, any Subsidiary or other Affiliate thereof or any other Person may at any time have against the beneficiary under any Letter of Credit, any Credit Party or any other Person, whether in connection with this Agreement, any other Loan Document or any other related or unrelated agreement or transaction, or any other act or omission to act or delay of any kind of any Credit Party 744315352 11074672 29 ALLETE CREDIT AGREEMENT or any other Person or any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section, constitute a legal or equitable discharge of, or provide a right of set-off against, the Borrower’s obligations hereunder. Neither any Credit Party nor any of their respective Related Parties shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of any Issuing Bank; provided that the foregoing shall not be construed to excuse an Issuing Bank from liability to the Borrower to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by the Borrower to the extent permitted by applicable law) suffered by the Borrower that are caused by any Issuing Bank’s failure to exercise care when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the part of any Issuing Bank (as finally determined by a court of competent jurisdiction), such Issuing Bank shall be deemed to have exercised care in each such determination. In furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to documents presented which appear on their face to be in substantial compliance with the terms of a Letter of Credit, any Issuing Bank may, in its sole discretion, either accept and make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit. (g) Disbursement Procedures. Each Issuing Bank shall, promptly following its receipt thereof, examine all documents purporting to represent a demand for payment under a Letter of Credit. Each Issuing Bank shall promptly notify the Administrative Agent and the Borrower by telephone (confirmed by telecopy or electronic mail) of such demand for payment and whether the Issuing Bank has made or will make an LC Disbursement thereunder; provided that any failure to give or delay in giving such notice shall not relieve the Borrower of its obligation to reimburse the applicable Issuing Bank and the Lenders with respect to any such LC Disbursement. (h) Interim Interest. If any Issuing Bank shall make any LC Disbursement, then, unless the Borrower shall reimburse such LC Disbursement in full on the date such LC Disbursement is made, the unpaid amount thereof shall bear interest, for each day from and including the date such LC Disbursement is made to but excluding the date that the Borrower reimburses such LC Disbursement, at the rate per annum then applicable to ABR Loans; provided that, if the Borrower fails to reimburse such LC Disbursement when due pursuant to paragraph (e) of this Section, then Section 3.1(b) shall apply. Interest accrued pursuant to this paragraph shall be for the account of the applicable Issuing Bank, except that interest accrued on and after the date of payment by any Lender pursuant to paragraph (e) of this Section to reimburse the applicable Issuing Bank shall be for the account of such Lender to the extent of such payment. (i) Replacement and Resignation of an Issuing Bank. (i) An Issuing Bank may be replaced at any time by written agreement among the Borrower, the Administrative Agent, the replaced Issuing Bank and the successor Issuing Bank. The Administrative Agent shall notify the Lenders of any such replacement of an Issuing Bank. At the time any such replacement shall become effective, the Borrower shall pay all unpaid fees accrued for the account of the replaced Issuing Bank pursuant to Section 3.3(b). From and after the effective date of any such replacement, (x) the successor Issuing Bank shall have all the rights and obligations of Issuing Banks under this Agreement with respect to Letters of Credit to be issued thereafter and (y) references herein to the term “Issuing Bank” shall be deemed to refer to such successor or to any previous Issuing Banks, or to such successor and all previous Issuing Banks, as the context shall require. After the replacement of an Issuing Bank hereunder, the replaced Issuing Bank shall remain a party hereto and shall continue to have all the rights and obligations of an Issuing Bank under this Agreement with respect to Letters of 744315352 11074672 30 ALLETE CREDIT AGREEMENT Credit issued by it prior to such replacement, but shall not be required to issue additional Letters of Credit. (ii) Subject to the appointment and acceptance of a successor Issuing Bank, any Issuing Bank may resign as an Issuing Bank at any time upon 30 days’ prior written notice to the Administrative Agent, the Borrower and the Lenders, in which case, such resigning Issuing Bank shall be replaced in accordance with Section 2.9(i) above. (j) Cash Collateral. In the event that (i) an Event of Default shall occur and be continuing or (ii) any Letter of Credit has an expiry date on or after the tenth Business Day prior to the Maturity Date (or any LC Disbursements remain unreimbursed on or after such date), the Borrower shall deposit with the Administrative Agent in immediately available funds on the Business Day on which it receives notice from the Administrative Agent or Required Lenders demanding the deposit of cash collateral in the case of clause (i), or no later than the tenth Business Day prior to the Maturity Date in the case of clause (ii), an amount equal to the Required Deposit Amount, which amount shall be held by the Administrative Agent for the benefit of the Lenders as cash collateral pursuant to a cash collateral agreement in form and substance satisfactory to the Administrative Agent and the applicable Issuing Banks to secure the Borrower’s reimbursement obligations with respect to LC Disbursements; provided that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Event of Default described in paragraph (i) or (j) of Article 8. Such deposit shall be held by the Administrative Agent as collateral for the payment and performance of the obligations of the Borrower under this Agreement. The Administrative Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account. Such deposit shall not bear interest, nor shall the Administrative Agent be under any obligation whatsoever to invest the same, provided that, at the request of the Borrower, such deposit shall be invested by the Administrative Agent in direct short term obligations of, or short term obligations the principal of and interest on which are unconditionally guaranteed by, the United States of America, in each case maturing no later than the expiry date of the Letter of Credit giving rise to the relevant LC Exposure. Interest or profits, if any, on such investments shall accumulate in such account. Moneys in such account shall be applied by the Administrative Agent to reimburse the applicable Issuing Bank for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrower for the LC Exposure at such time or, if the maturity of the Loans has been accelerated (but subject to the consent of Required Lenders), be applied to satisfy other obligations of the Borrower under this Agreement. If the Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, such amount (to the extent not applied as aforesaid) shall be returned to the Borrower within three Business Days after all Events of Default have been cured or waived.

Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its office at 10 S. Dearborn, Chicago, Illinois, or such other office as to which the Administrative Agent may notify the other parties hereto, 744315352 11074672 31 ALLETE CREDIT AGREEMENT except that payments pursuant to Sections 3.3(b) (with respect to the fronting fee and other amounts payable to the Issuing Banks), 3.3(c), 3.5, 3.6, 3.7 and 10.3 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments hereunder shall be made in dollars. (b) Each Borrowing, each payment or prepayment of principal of any Borrowing, each payment of interest on the Loans, each payment of fees, each reduction of the Commitments and each conversion of any Borrowing to or continuation of any Borrowing as a Borrowing of any Type shall be allocated pro rata among the Lenders in accordance with their respective applicable Commitments (or, if such Commitments shall have expired or been terminated, in accordance with the respective principal amounts of their outstanding Loans). Each Lender agrees that in computing such Lender’s portion of any Borrowing to be made hereunder, the Administrative Agent may, in its discretion, round each Lender’s percentage of such Borrowing to the next higher or lower whole dollar amount. If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal of Loans, unreimbursed LC Disbursements, interest, fees and commissions then due hereunder, such funds shall be applied first, towards payment of interest, fees and commissions then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest, fees and commissions then due to such parties and second, towards payment of principal of Loans and unreimbursed LC Disbursements then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal of Loans and unreimbursed LC Disbursements then due to such parties. (c) If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of, or interest on, any of its Loans or participations in LC Disbursements resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and participations in LC Disbursements and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans and participations in LC Disbursements of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of, and accrued interest on, their respective Loans and participations in LC Disbursements, provided that if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and the provisions of this paragraph shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in LC Disbursements to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation. (d) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the applicable Credit Parties hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to such Credit Parties the amount due. In such event, if the Borrower has not in fact made such payment, then each such Credit Party severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Credit Party with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the 744315352 11074672 32 ALLETE CREDIT AGREEMENT greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

(d) In the event that the Administrative Agent, the Borrower and each Issuing Bank agree that a Defaulting Lender has adequately remedied all matters that caused such Lender to be a Defaulting Lender, then the LC Exposure of the Lenders shall be readjusted to reflect the inclusion of such Lender’s Commitments and on such date such Lender shall purchase at par such of the Loans of the other Lenders as the Administrative Agent shall determine may be necessary in order for such Lender to hold such Loans in accordance with its Applicable Percentage, and all cash collateral and accrued interest thereon held by the Administrative Agent or the applicable Issuing Banks shall be returned to the Borrower forthwith.

(a) (b) The Person serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent, and such Person and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate thereof as if it were not the Administrative Agent hereunder. (c) As to any matters not expressly provided for herein and in the other Loan Documents (including enforcement or collection), the Administrative Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the written instructions of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary, pursuant to the terms in the Loan Documents), and, unless and until revoked in writing, such instructions shall be binding upon each Lender and each Issuing Bank; provided, however, that the Administrative Agent shall not be required to take any action that (i) the Administrative Agent in good faith believes exposes it to liability unless the Administrative Agent receives an indemnification and is exculpated in a manner satisfactory to it from the Lenders and the Issuing Banks with respect to such action or (ii) is contrary to this Agreement or any other Loan Document or applicable law, including any action that may be in violation of the automatic stay under any requirement of law relating to bankruptcy, insolvency or reorganization or relief of debtors or that may effect a forfeiture, modification or termination of property of a Defaulting Lender in violation of any requirement of law relating to bankruptcy, insolvency or reorganization or relief of debtors; provided, further, that the Administrative Agent may seek clarification or direction from the Required Lenders prior to the exercise of any such instructed action and may refrain from acting until such clarification or direction has been provided.

(d) In performing its functions and duties hereunder and under the other Loan Documents, the Administrative Agent is acting solely on behalf of the Lenders and the Issuing Banks (except in limited circumstances expressly provided for herein relating to the maintenance of the Register), and its duties are entirely mechanical and administrative in nature. Without limiting the generality of the foregoing: (i) the Administrative Agent does not assume and shall not be deemed to have assumed any obligation or duty or any other relationship as the agent, fiduciary or trustee of or for any Lender or Issuing Bank other than as expressly set forth herein and in the other Loan Documents, regardless of whether a Default or an Event of Default has occurred and is continuing (and it is understood and agreed that the use of the term “agent” (or any similar term) herein or in any other Loan Document with reference to the Administrative Agent is not intended to connote any fiduciary duty or other implied (or express) obligations arising under agency doctrine of any applicable law, and that such term is used as a matter of market custom and is intended to create or reflect only an administrative relationship between contracting parties); additionally, each Lender agrees that it will not assert any claim against the Administrative Agent based on an alleged breach of fiduciary duty by the Administrative Agent in connection with this Agreement and/or the transactions contemplated hereby; and (ii) nothing in this Agreement or any Loan Document shall require the Administrative Agent to account to any Lender for any sum or the profit element of any sum received by the Administrative Agent for its own account; (e) The Administrative Agent may perform any of its duties and exercise its rights and powers hereunder or under any other Loan Document by or through any one or more sub-agents appointed by the Administrative Agent.

(b) The Administrative Agent shall be deemed not to have knowledge of any Default unless and until written notice thereof (stating that it is a “notice of default”) is given to the Administrative Agent by the Borrower, a Lender or an Issuing Bank, and the Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with any Loan Document, (ii) the contents of any certificate, report or other document delivered thereunder or in connection therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth in any Loan Document or the occurrence of any Default, (iv) the sufficiency, validity, enforceability, effectiveness or genuineness of any Loan Document or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article 5 or elsewhere in any Loan Document, other than to confirm receipt of items (which on their face purport to be such items) expressly required to be delivered to the Administrative Agent or satisfaction of any condition that expressly refers to the matters described therein being acceptable or satisfactory to the Administrative Agent.

Section 1.3. Posting of Communications; Limitation of Liability. The Borrower agrees that the Administrative Agent may, but shall not be obligated to, make any Communications available to the Lenders and the Issuing Banks by posting the Communications on IntraLinks™, DebtDomain, SyndTrak, ClearPar or any other electronic platform chosen by the Administrative Agent to be its electronic transmission system (the “Approved Electronic Platform”). (a) (b) Although the Approved Electronic Platform and its primary web portal are secured with generally-applicable security procedures and policies implemented or modified by the Administrative Agent from time to time (including, as of the Effective Date, a user ID/password authorization system) and the Approved Electronic Platform is secured through a per-deal authorization method whereby each user may access the Approved Electronic Platform only on a deal-by-deal basis, each of the Lenders, each of the Issuing Banks and the Borrower acknowledges and agrees that the distribution of material through an electronic medium is not necessarily secure, that the Administrative Agent is not responsible for approving or vetting the representatives or contacts of any Lender that are added to the Approved Electronic Platform, and that there may be confidentiality and other risks associated with such distribution. Each of the Lenders, each of the Issuing Banks and the Borrower hereby approves distribution of the Communications through the Approved Electronic Platform and understands and assumes the risks of such distribution. (c) THE APPROVED ELECTRONIC PLATFORM AND THE COMMUNICATIONS ARE PROVIDED “AS IS” AND “AS AVAILABLE”. THE APPLICABLE PARTIES DO NOT WARRANT THE ACCURACY OR COMPLETENESS OF THE COMMUNICATIONS, OR THE ADEQUACY OF THE APPROVED ELECTRONIC PLATFORM AND EXPRESSLY DISCLAIM LIABILITY FOR ERRORS OR OMISSIONS IN THE APPROVED ELECTRONIC PLATFORM AND THE COMMUNICATIONS. NO WARRANTY OF ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT OF THIRD PARTY RIGHTS OR FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS, IS MADE BY THE APPLICABLE PARTIES IN CONNECTION WITH THE COMMUNICATIONS OR THE APPROVED ELECTRONIC PLATFORM. IN NO EVENT SHALL THE ADMINISTRATIVE AGENT, THE SOLE LEAD ARRANGER AND SOLE BOOKRUNNER OR ANY OF THEIR RESPECTIVE RELATED PARTIES (COLLECTIVELY, “APPLICABLE PARTIES”) HAVE ANY LIABILITY TO ANY LENDER, ANY ISSUING BANK OR ANY OTHER PERSON OR ENTITY FOR DAMAGES OF ANY KIND, INCLUDING DIRECT OR INDIRECT, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES, LOSSES OR EXPENSES (WHETHER IN TORT, CONTRACT OR OTHERWISE) 744315352 11074672 60 ALLETE CREDIT AGREEMENT ARISING OUT OF THE BORROWER’S OR THE ADMINISTRATIVE AGENT’S TRANSMISSION OF COMMUNICATIONS THROUGH THE INTERNET OR THE APPROVED ELECTRONIC PLATFORM. NO CREDIT PARTY NOR ANY OF THEIR RESPECTIVE RELATED PARTIES SHALL BE LIABLE TO THE BORROWER FOR ANY USE BY OTHERS OF INFORMATION OR OTHER MATERIALS (INCLUDING, WITHOUT LIMITATION, ANY PERSONAL DATA) OBTAINED THROUGH TELECOMMUNICATIONS, ELECTRONIC OR OTHER INFORMATION TRANSMISSION SYSTEMS (INCLUDING THE ELECTRONIC PLATFORM) EXCEPT TO THE EXTENT SUCH LIABILITIES ARE FOUND IN A FINAL JUDGMENT BY A COURT OF COMPETENT JURISDICTION TO HAVE ARISEN FROM SUCH PARTY’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. “Communications” means, collectively, any notice, demand, communication, information, document or other material provided by or on behalf of the Borrower pursuant to any Loan Document or the transactions contemplated therein which is distributed by the Administrative Agent, any Lender or any Issuing Bank by means of electronic communications pursuant to this Section, including through an Approved Electronic Platform. (d) Each Lender and each Issuing Bank agrees that notice to it (as provided in the next sentence) specifying that Communications have been posted to the Approved Electronic Platform shall constitute effective delivery of the Communications to such Lender for purposes of the Loan Documents. Each Lender and Issuing Bank agrees (i) to notify the Administrative Agent in writing (which could be in the form of electronic communication) from time to time of such Lender’s or Issuing Bank’s (as applicable) email address to which the foregoing notice may be sent by electronic transmission and (ii) that the foregoing notice may be sent to such email address. Each of the Lenders, each of the Issuing Banks and the Borrower agrees that the Administrative Agent may, but (except as may be required by applicable law) shall not be obligated to, store the Communications on the Approved Electronic Platform in accordance with the Administrative Agent’s generally applicable document retention procedures and policies. (e) notice or other communication pursuant to any Loan Document in any other manner specified in such Loan Document. (f) Nothing herein shall prejudice the right of the Administrative Agent, any Lender or any Issuing Bank to give any Section 1.4. The Administrative Agent Individually. With respect to its Commitment, Loans, Letter of Credit Commitments and Letters of Credit, the Person serving as the Administrative Agent shall have and may exercise the same rights and powers hereunder and is subject to the same obligations and liabilities as and to the extent set forth herein for any other Lender or Issuing Bank, as the case may be. The terms “Issuing Banks”, “Lenders”, “Required Lenders” and any similar terms shall, unless the context clearly otherwise indicates, include the Administrative Agent in its individual capacity as a Lender, Issuing Bank or as one of the Required Lenders, as applicable. The Person serving as the Administrative Agent and its Affiliates may accept deposits from, lend money to, own securities of, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of banking, trust or other business with, the Borrower, any Subsidiary or any Affiliate of any of the foregoing as if such Person was not acting as the Administrative Agent and without any duty to account therefor to the Lenders or the Issuing Banks.

(a) The Administrative Agent may resign at any time by giving 30 days’ prior written notice thereof to the Lenders, the Issuing Banks and the Borrower, whether or not a successor Administrative Agent has been appointed. Upon any such resignation, the Required Lenders shall have the right to appoint a successor Administrative Agent. If no successor Administrative Agent shall have been so appointed by the Required Lenders, and shall have accepted such appointment, within 30 days 744315352 11074672 61 ALLETE CREDIT AGREEMENT after the retiring Administrative Agent’s giving of notice of resignation, then the retiring Administrative Agent may, on behalf of the Lenders and the Issuing Banks, appoint a successor Administrative Agent, which shall be a bank with an office in New York, New York or an Affiliate of any such bank. In either case, such appointment shall be subject to the prior written approval of the Borrower (which approval may not be unreasonably withheld and shall not be required while an Event of Default has occurred and is continuing). Upon the acceptance of any appointment as Administrative Agent by a successor Administrative Agent, such successor Administrative Agent shall succeed to, and become vested with, all the rights, powers, privileges and duties of the retiring Administrative Agent. Upon the acceptance of appointment as Administrative Agent by a successor Administrative Agent, the retiring Administrative Agent shall be discharged from its duties and obligations under this Agreement and the other Loan Documents. Prior to any retiring Administrative Agent’s resignation hereunder as Administrative Agent, the retiring Administrative Agent shall take such action as may be reasonably necessary to assign to the successor Administrative Agent its rights as Administrative Agent under the Loan Documents. (b) Notwithstanding paragraph (a) of this Section, in the event no successor Administrative Agent shall have been so appointed and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its intent to resign, the retiring Administrative Agent may give notice of the effectiveness of its resignation to the Lenders, the Issuing Banks and the Borrower, whereupon, on the date of effectiveness of such resignation stated in such notice, (i) the retiring Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents; and (ii) the Required Lenders shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent; provided that (A) all payments required to be made hereunder or under any other Loan Document to the Administrative Agent for the account of any Person other than the Administrative Agent shall be made directly to such Person and (B) all notices and other communications required or contemplated to be given or made to the Administrative Agent shall directly be given or made to each Lender and each Issuing Bank. Following the effectiveness of the Administrative Agent’s resignation from its capacity as such, the provisions of this Article and Section 10.3, as well as any exculpatory, reimbursement and indemnification provisions set forth in any other Loan Document, shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring Administrative Agent was acting as Administrative Agent.

(a) Each Lender represents that it is engaged in making, acquiring or holding commercial loans in the ordinary course of its business and that it has, independently and without reliance upon the Administrative Agent, the Sole Lead Arranger and Sole Bookrunner or any other Lender, or any of the Related Parties of any of the foregoing, and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement as a Lender, and to make, acquire or hold Loans hereunder. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent, the Sole Lead Arranger and Sole Bookrunner or any other Lender, or any of the Related Parties of any of the foregoing, and based on such documents and information (which may contain material, non-public information within the meaning of the United States securities laws concerning the Borrower and its Affiliates) as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder. (b) Each Lender, by delivering its signature page to this Agreement on the Effective Date, or delivering its signature page to an Assignment and Assumption or any other Loan Document pursuant to which it shall become a Lender hereunder, shall be deemed to have acknowledged receipt of, and consented to and approved, each Loan Document and each other document required to be delivered to, or be approved by or satisfactory to, the Administrative Agent or the Lenders on the Effective Date. 744315352 11074672 62 ALLETE CREDIT AGREEMENT Section 1.7.

(b) In addition, unless sub-clause (i) in the immediately preceding clause (a) is true with respect to a Lender or such Lender has not provided another representation, warranty and covenant as provided in sub-clause (iv) in the immediately preceding clause (a), such Lender further (x) represents and warrants, as of the date such Person became a Lender party hereto, to, and (y) covenants, from the date such Person became a Lender party hereto to the date such Person ceases being a Lender party hereto, for the benefit of, the Administrative Agent and the Sole Lead Arranger and Sole Bookrunner and their respective Affiliates, and not, for the avoidance of doubt, to or for the benefit of the Borrower, that none of the Administrative Agent or any of their respective Affiliates is a fiduciary with respect to the assets of such Lender (including in connection with the reservation or exercise of any rights by the Administrative Agent under this Agreement, any Loan Document or any documents related to hereto or thereto). (c) The Administrative Agent and the Sole Lead Arranger and Sole Bookrunner hereby inform the Lenders that each such Person is not undertaking to provide investment advice or to give advice in a fiduciary capacity, in connection with the transactions contemplated hereby, and that such Person has a financial interest in the transactions contemplated hereby in that such Person or an Affiliate thereof (i) may receive interest or other payments with respect to the Loans, the Letters of Credit, the Commitments, this Agreement and any other Loan Documents (ii) may recognize a gain if it extended the Loans, the Letters of Credit or the Commitments for an amount less than the amount being paid for an interest in the Loans, the Letters of Credit or the Commitments by such Lender or 744315352 11074672 63 ALLETE CREDIT AGREEMENT (iii) may receive fees or other payments in connection with the transactions contemplated hereby, the Loan Documents or otherwise, including structuring fees, commitment fees, arrangement fees, facility fees, upfront fees, underwriting fees, ticking fees, agency fees, administrative agent or collateral agent fees, utilization fees, minimum usage fees, letter of credit fees, fronting fees, deal-away or alternate transaction fees, amendment fees, processing fees, term out premiums, banker’s acceptance fees, breakage or other early termination fees or fees similar to the foregoing.

Section 1.17. CoBank Equity and Security. (a) So long as CoBank (or its Affiliate) is a Lender hereunder, the Borrower will (i) maintain its status as an entity eligible to borrow from CoBank and (ii) acquire equity in CoBank in such amounts and at such times as CoBank may require in accordance with CoBank’s Bylaws and Capital Plan, except that the maximum amount of equity that the Borrower may be required to purchase in CoBank in connection with the Loans made by CoBank (or its affiliate) may not exceed the maximum amount permitted by the Bylaws and the Capital Plan at the time this Agreement is entered into. The Borrower acknowledges receipt of a copy of (x) CoBank’s most recent annual report, and if more recent, CoBank’s latest quarterly report, (y) CoBank’s Notice to Prospective Stockholders and (iii) CoBank’s Bylaws and Capital Plan, which describe the nature of all of the Borrower’s cash patronage, stock and other equities in CoBank acquired in connection with its patronage loan from CoBank (or its Affiliate) (the “CoBank Equities”) as well as capitalization requirements, and agrees to be bound by the terms thereof. (b) Each party hereto acknowledges that CoBank’s Bylaws and Capital Plan shall govern (i) the rights and obligations of the parties with respect to the CoBank Equities and any patronage refunds or other distributions made on account thereof or on account of the Borrower’s patronage with CoBank, (ii) the Borrower’s eligibility for patronage distributions from CoBank (in the form of CoBank Equities and cash) and (iii) patronage distributions, if any, in the event of a sale of a participation interest. CoBank reserves the right to assign or sell participations in all or any part of its (or its Affiliate’s) Commitments or outstanding Loans hereunder on a non-patronage basis. 744315352 11074672 75 ALLETE CREDIT AGREEMENT (c) Each party hereto acknowledges that CoBank has a statutory first lien pursuant to the Farm Credit Act of 1971 (as amended from time to time) on all CoBank Equities that the Borrower may now own or hereafter acquire, which statutory lien shall be for CoBank’s (or its Affiliate’s) sole and exclusive benefit. The CoBank Equities shall not constitute security for the obligations due to any other Lender. To the extent that any of the Loan Documents create a Lien on the CoBank Equities or on patronage accrued by CoBank for the account of the Borrower (including, in each case, proceeds thereof), such Lien shall be for CoBank’s (or its Affiliate’s) sole and exclusive benefit and shall not be subject to pro rata sharing hereunder. Neither the CoBank Equities nor any accrued patronage shall be offset against the obligations hereunder, except that, in the event of an Event of Default, CoBank may elect, solely at its discretion, to apply the cash portion of any patronage distribution or retirement of equity to amounts owed to CoBank or its Affiliate under this Agreement, whether or not such amounts are currently due and payable. The Borrower acknowledges that any corresponding tax liability associated with such application is the sole responsibility of the Borrower. CoBank shall have no obligation to retire the CoBank Equities upon any Default or any other default by the Borrower, or at any other time, either for application to the Loans or other obligations under this Agreement or otherwise. Section 1.18. Acknowledgement and Consent to Bail-In of Affected Financial Institutions. Notwithstanding anything to the contrary in any Loan Document or in any other agreement, arrangement or understanding among any such parties, each party hereto acknowledges that any liability of any Affected Financial Institution arising under any Loan Document may be subject to the Write-Down and Conversion Powers of the applicable Resolution Authority and agrees and consents to, and acknowledges and agrees to be bound by: liabilities arising hereunder which may be payable to it by any party hereto that is an EEA Financial Institution; and (a) the application of any Write-Down and Conversion Powers by the applicable Resolution Authority to any such (b) the effects of any Bail-In Action on any such liability, including, if applicable: (i) a reduction in full or in part or cancellation of any such liability; (ii) a conversion of all, or a portion of, such liability into shares or other instruments of ownership in such Affected Financial Institution, its parent entity, or a bridge institution that may be issued to it or otherwise conferred on it, and that such shares or other instruments of ownership will be accepted by it in lieu of any rights with respect to any such liability under this Agreement or any other Loan Document; or (iii) the variation of the terms of such liability in connection with the exercise of the Write-Down and Conversion Powers of the applicable Resolution Authority.

This document includes the terms of the ALLETE and Affiliated Companies Supplemental Executive Retirement Plan II. The purpose of SERP II is to provide eligible Employees an opportunity to elect to defer compensation. SERP II also provides eligible Employees a supplemental Retirement Benefit designed to compensate for annual compensation limits and maximum benefit limitations imposed by the Code on Retirement Plans maintained by the Company. SERP II is a successor to the ALLETE and Affiliated Companies Supplemental Executive Retirement Plan (“SERP I”). On December 31, 2004, the Company froze SERP I with respect to all deferrals and vested accrued Retirement Benefits (if any). On January 1, 2005, the Company established SERP II to govern (a) amounts initially deferred after December 31, 2004 and investment earnings thereon; (b) Retirement Benefit accruals after December 31, 2004; and (c) accrued but unvested SERP I Retirement Benefits as of December 31, 2004. From January 1, 2005 to the effective date hereof, the Company operated and administered the Plan in all material respects in good faith compliance with the applicable requirements of Section 409A, the final and proposed Treasury Regulations, IRS Notice 2005-1, and all other IRS guidance. The Company amended and restated SERP II in its entirety, effective January 1, 2009, to comply with Section 409A. The Company intends that SERP II constitute an unfunded deferred compensation plan for a select group of management or highly compensated employees within the meaning of ERISA sections 201(2), 301(a)(3) and 401(a)(1). All provisions of SERP II shall be interpreted and administered to the extent possible in a manner consistent with the stated intentions. Effective January 20, 2009, the Company amended SERP II to narrow the salary-grade eligibility requirements to receive an Annual Make-Up Award for employees who first became eligible to participate in SERP II after September 30, 2006. Effective January 1, 2011, the Company amended SERP II to incorporate any compensation recovery policy adopted by the Company and to provide that certain benefits may be subject to forfeiture for Misconduct. Effective January 1, 2015, the Company amended SERP II to reflect the reduction to the Flexible Dollar Makeup in connection with amendments to the ALLETE and Affiliated Companies Flexible Compensation Plan that eliminate the life insurance percentage (age-rated) flexible dollars benefit commencing with the Plan Year that begins on January 1, 2015. Effective January 1, 2019, the Company hereby amends SERP II to and to narrow the salary-grade eligibility requirements to defer compensation, to reflect the discontinuation of additional non-elective 162(m) Deferrals beginning with the Plan Year that commences on January 1, 2019, to freeze credited service as of December 31, 2018, for 2  Exhibit 10(f)5 all Participants eligible for a SERP II Retirement Benefit, and to modify the amount of the Annual Make-up Award. Effective January 1, 2021, the Company hereby amends SERP II to freeze final average earnings for Retirement Benefit purposes as of the earlier of a Participant’s Separation from Service or December 31, 2021, and to clarify the Salary used to determine Annual Make-up Awards. Capitalized terms, unless otherwise defined herein, shall have the meaning provided in Appendix A. 1.2 Compensation Recovery Policy. All amounts payable to Participants in accordance with this Plan are subject to, and the Company hereby incorporates into this SERP II, the terms of any compensation recovery policy or policies established and amended by the Company from time to time (“Compensation Recovery Policy”). ARTICLE 2 Section 409A Plans and Organization 1.1 Section 409A Plans. The provisions of SERP II include terms and conditions applicable to the following 409A Plans: 1.1.1 An elective account balance plan for Employees for purposes of Elective Deferrals; 1.1.2 A non-elective account balance plan for Employees for purposes of Non-Elective Deferrals; and 1.1.3 A non-account balance plan for Employees. 1.2 Organization. Except as otherwise provided in this section or in a specific section, all provisions of the Plan apply to all amounts deferred under any Article of the Plan. 1.1.1 The provisions of Article 5 apply only for purposes of identifying employees eligible to receive an Annual Make- Up Award and the amount of the award, if any. 1.1.2 The provisions of Articles 6 and 7 apply only to the extent that SERP II provides for Employees’ Elective Deferrals, or Non-Elective Deferrals or both, which, for purposes of Section 409A, represent the elective and non- elective account balance plans identified in subsections 2.1.1 and 2.1.2, respectively. 1.1.3 The provisions of Article 8 apply only to the extent that SERP II provides for Retirement Benefits, which represent the non-account balance plan identified in subsection 2.1.3. 1.3 Section 409A Compliance. To the extent that any provision of the Plan would cause a conflict with the requirements of Section 409A, or would cause the administration of the Plan to fail to satisfy Section 409A, such provision shall be deemed null and void to the extent permitted by applicable law. Nothing herein shall be construed as a guarantee of any particular tax treatment to a Participant. 3  Exhibit 10(f)5 1.1 1.2 1.3 1.4 1.5 1.1 1.2 ARTICLE 3 Administration Administrator. The Administrator shall administer the Plan or may delegate any of its duties to such other person or persons from time to time as it may designate. Members of the Employee Benefit Plans Committee may participate in SERP II; however, any individual serving on the Employee Benefit Plans Committee shall not vote or act on any matter relating solely to himself or herself. Duties. The Administrator has the authority to construe and interpret all provisions of the Plan and, to the extent permitted by Section 409A, the Administrator is authorized to remedy any errors, inconsistencies or omissions, to resolve any ambiguities, to adopt rules and practices concerning the administration of the Plan, and to make any determinations and calculations necessary or appropriate hereunder. The Company shall pay all expenses and liabilities incurred in connection with Plan administration. Agents. The Administrator may engage the services of accountants, attorneys, actuaries, investment consultants, and such other professional personnel as are deemed necessary or advisable to assist in fulfilling the Administrator’s responsibilities. The Administrator, the Company and the Board may rely upon the advice, opinions or valuations of any such persons. Binding Effect of Decisions. The decision or action of the Administrator with respect to any question arising out of or in connection with the administration, interpretation and application of the Plan and the rules and regulations promulgated hereunder shall be final, conclusive and binding upon all persons having any interest in the Plan. Neither the Administrator, its delegates, nor the Board shall be personally liable for any good faith action, determination or interpretation with respect to the Plan, and each shall be fully protected by the Company in respect of any such action, determination or interpretation. Employer Information. To enable the Administrator to perform its duties, each Employer shall supply full and timely information to the Administrator on all matters relating to the compensation of its Participants, the date and circumstances of the Participant’s death, Disability or Separation from Service, and other pertinent information as the Administrator may reasonably require. ARTICLE 4 Participation Eligibility and Commencement of Participation. Eligible Employees may participate in the Plan, except to the extent provided in Section 8.1 regarding eligibility for Retirement Benefits. Each Plan Year, the Administrator shall notify Eligible Employees of their eligibility to participate in the Plan during the following Plan Year. An Eligible Employee shall become a Participant either upon the initial submission of an election form on which the Eligible Employee has elected Elective Deferrals or upon first receiving an allocation of Non-Elective Deferrals. Special Rule for Initial Participation. Within 30 days after the date an individual first becomes an Eligible Employee, the individual may elect to commence participating with respect to compensation to be paid for services performed after the election is filed. This election relating to initial participation in the Plan is available only to Participants who do not participate in any Aggregated Plans. If an Employee whose participation in the Plan is terminated again becomes an Eligible Employee, he or she may elect to defer pursuant 4  Exhibit 10(f)5 1.3 1.1 1.2 to this Section only if the Employee was ineligible to defer compensation in this Plan and all other Related Company elective account balance plans, within the meaning of Section 409A, for the 24 months preceding the date on which the Participant again became eligible to participate in this Plan. Termination of Participation. If the Administrator determines in good faith that a Participant is no longer an Eligible Employee, the Participant shall cease active participation in the Plan on the last day of the Plan Year during which the Participant ceased to be an Eligible Employee, and the terms of this Plan shall continue to govern Participant’s Account until the Participant’s Account is paid in full. ARTICLE 5 Annual Make-Up Award Eligibility. An Employee who: (i) was a Participant as of September 30, 2006, (ii) has continuously remained an Employee in ALLETE management salary grade SA-SM, and (iii) has continuously participated in the ALLETE Executive Annual Incentive Plan or been eligible to receive a Bonus shall be eligible to receive an Annual Make-up Award. Any other Employee shall be eligible to receive an Annual Make-up Award if the Employee: (i) initially becomes, or again becomes, a Participant after September 30, 2006, (ii) is in ALLETE management salary grade SG-SM, and (iii) participates in the ALLETE Executive Annual Incentive Plan or is eligible to receive a Bonus. Amount of Annual Make-Up Award. Commencing with the Plan Year that begins on January 1, 2019, the Annual Make-Up Award shall equal the product of 13% and an amount equal to the sum of: (a) the total of the Participant’s Annual Incentive Award and other awards (to the extent included in calculations for the Retirement Plans) for such year, and (b) the Participant’s Salary in excess of the Code section 401(a)(17) limitation in effect for the Plan Year. 1.3 Payment. Except to the extent deferred in accordance with this Plan, the Annual Make-Up Award for any year shall be paid between January 1 and March 15 of the year following the year to which the award relates. 1.4 Forfeiture of Annual Make-Up Award. Notwithstanding any other term or provision of this Article 5, if a Participant engages in Misconduct, the Participant shall forfeit or repay, as necessary, any Annual Make-Up Award payable on account of the period during which the Misconduct occurred and any subsequent period. In addition, notwithstanding any other term or provison of this Article 5, if a Partipant has a Separation from Service that is not also a Retirement, the Participant shall forfeit any Annual Make-Up Award that has not yet been paid to the Participant. 5  Exhibit 10(f)5 1.1 Elective Deferrals. ARTICLE 6 SERP II Account Balance Plan for Employees 1.1.1 Eligibility. Beginning with the Plan year that commences on January 1, 2019, only employees in ALLETE management salary grade SG-SM will be eligible to elect to make elective deferrals in accordance with this Article 6. 1.1.2 Deferral Elections. For each Plan Year, an eligible Participant may elect to defer some or all of Salary, Bonus, and, if eligible, an Annual Make-up Award, Severance Pay, and Other Awards. Elections are effective on a calendar year basis and become irrevocable no later than the date specified by the Administrator, but in any event before the beginning of the Plan Year to which the elections relate. An eligible Participant’s elections will become effective only if the forms required by the Administrator have been properly completed and signed by the Participant, timely delivered to the Administrator, and accepted by the Administrator. An eligible Participant who fails to file elections before the required date will be treated as having elected not to defer any amounts for the following Plan Year. For any Plan Year the Administrator may, in its sole discretion, decide not to allow one or more Participants to defer certain types of compensation. 1.1.3 Special Rule for Performance-Based Compensation. The Administrator, in its complete and sole discretion, may allow a Participant to revise a deferral election with respect to a Bonus if the Administrator determines that the Bonus is performance-based compensation within the meaning of Section 409A and the election becomes irrevocable no later than the earlier of: (a) six months preceding the end of the performance period to which the Bonus relates; or (b) the date as of which the Bonus has become readily ascertainable, within the meaning of Section 409A. 1.1.4 Special Rule for Severance Pay. An eligible Participant may elect to defer all or a portion of Severance Pay by filing with the Administrator an irrevocable deferral election no later than the date the Participant obtains a legally binding right to the Severance Pay. 1.1.5 Cancellation of Deferral Election due to Disability. If an eligible Participant becomes disabled, the Administrator may, in its sole discretion, cancel the Participant’s deferral election, with respect to amounts to be deferred on or after the cancellation, by the end of the year during which the Participant becomes disabled, or, if later, the 15 day of the third month following the date on which the Participant becomes disabled.

The Administrator shall notify the Claimant, in language calculated to be understood by the Claimant: 1.1.1 That the claim has been allowed in full; or 1.1.2 That the claim has been denied, in whole or in part, and such notice must set forth: (a) Specific reasons for the decision; 17  Exhibit 10(f)5 (b) (c) (d) (e) Specific reference(s) to the pertinent Plan provisions upon which the decision was based; A statement that Claimant is entitled to reasonable access to, and copies of, all documents, records or other information relevant to the claim upon request and free of charge; A statement regarding the Claimant’s right to initiate an action pursuant to section 502(a) of ERISA; and Such other matters as the Administrator deems relevant. 1.1.3 In the case of a claim for disability benefits, the notice shall set forth: (a) Whether the Administrator’s denial relied upon any specific rule, guideline, protocol or scientific or clinical judgment; and (b) The following statement: “You and your Plan may have other voluntary alternative dispute resolution options, such as mediation. One way to find out what may be available is to contact your local U.S. Department of Labor Office and your State insurance regulatory agency.” 1.5 Other Remedies. A Claimant’s compliance with the foregoing procedures is a mandatory prerequisite to a Claimant’s right to pursue any other remedy with respect to any claim relating to this Plan. ARTICLE 12 Amendment or Termination The Company hereby reserves the right to amend, modify, or terminate any one or more of the 409A Plans, at any time by action of the Board, with or without prior notice. No amendment or termination shall reduce any Participant’s Account or Retirement Benefit without the written consent of the affected Participant. Notwithstanding anything herein to the contrary, to the extent consistent with Section 409A, the Board may terminate the Plan and distribute to each Participant the Participant’s Account and the Participant’s Retirement Benefit, if any, in a lump sum; provided that all distributions (i) commence no earlier than the date that is twelve (12) months following the termination date (or any earlier date that would comply with Section 409A) and (ii) are completed by the date that is twenty-four (24) months following the termination date (or any later date that would comply with Section 409A). In addition, payments may be accelerated upon termination of any 409A Plan only if, to the extent required under Section 409A, (i) the Company terminates all Aggregated Plans, and (ii) for three years following the date of termination of the 409A Plan, the Company does not adopt any new arrangement that would have been an Aggregated Plan of the terminated 409A Plan. ARTICLE 13 Miscellaneous Provisions 1.1 Unsecured General Creditor. Participants and their Beneficiaries, heirs, successors and assigns shall have no legal or equitable rights, interests or claims in any property or assets of an Employer.

An Employer’s liability for benefits shall be defined only by the Plan. An Employer shall have no obligation to a Participant except as expressly provided in the Plan. Nonassignability.

Incompetency. If the Administrator determines that a distribution under this Plan is to be paid to a minor, a person declared incompetent or to a person incapable of handling the disposition of that person’s property, the Administrator may direct such distribution to be paid to the guardian, legal representative or person having the care and custody of such minor, incompetent or incapable person. The Administrator may require proof of majority, competence, capacity, guardianship, or status as a legal representative as it may deem appropriate prior to distribution of a payment. Any distribution shall be a payment for the account of the Participant and the Participant’s Beneficiary, as the case may be, and shall be a complete discharge of any liability for such payment amount. Tax Withholding. To the extent required by the law in effect at the time of any distribution, the Participant’s Employer shall withhold from any payments to a Participant hereunder any taxes required to be withheld by the federal or any state or local government, in amounts and in a manner to be determined in the sole discretion of the Employer(s).

The Plan shall be governed by, construed and administered in accordance with the applicable provisions of ERISA, and any other applicable Federal law, including Section 409A, and to the extent not preempted by Federal law, this Plan shall be governed by, construed and administered in accordance with the laws of the State of Minnesota, other than its laws respecting choice of law. 1.12 1.13 Invalid or Unenforceable Provisions. If any provision of this Plan shall be held invalid or unenforceable, such invalidity or unenforceability shall not affect any other provisions hereof and the Administrator may elect in its sole discretion to construe such invalid or unenforceable provisions in a manner that conforms to applicable law or as if such provisions, to the extent invalid or unenforceable, had not been included. Successors. This Plan shall bind any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business or assets of the Company, in the same manner and to the same extent that the Company would be obligated under this Plan if no succession had taken place. In the case of any transaction in which a successor would not by the foregoing provision or by operation of law be bound by this Plan, the Company shall require such successor expressly and unconditionally to assume and agree to perform the obligations of the Company and each Employer under this Plan, in the same manner and to the same extent that the Company and each Employer would be required to perform if no such succession had taken place. 20  Exhibit 10(f)5 APPENDIX A “162(m) Deferrals” means the portion of a Participant’s Annual Incentive Award for a Plan Year ending on or before December 31, 2018, that the Company reasonably anticipates is not deductible by the application of Code section 162(m). “409A Plan” means one of the separate non-qualified deferred compensation arrangements described in Section 2.1. “Account” means the Company’s bookkeeping entry representing a Participant’s Deferrals, and such other accounts or sub-accounts as the Administrator deems necessary or appropriate. “Administrator” means the Employee Benefit Plans Committee appointed by the Board or delegates of the Employee Benefit Plans Committee. “Aggregated Plans” means, with respect to any 409A Plan, that plan and all other non-qualified deferred compensation plans which must be aggregated with that plan in accordance with the plan aggregation rules of Section 409A. “Annual Incentive Award” means the annual award received by a Participant under the ALLETE Executive Annual Incentive Plan or any predecessor or successor plan. “Basic Compensation” shall have the meaning prescribed in Retirement Plan A except:(1) Basic Compensation shall be calculated without regard to the limitation on compensation imposed by Code section 401(a)(17); and (2) for Retirement Benefit purposes, only compensation earned through December 31, 2021 shall be considered. “Beneficiary” means one or more persons, trusts, estates or other entities, designated in accordance this Plan, that are entitled to receive Plan benefits upon the death of a Participant. “Board” means the Board of Directors of the Company. “Bonus” means any incentive compensation, including Annual Incentive Awards, that is payable to the Participant in addition to the Participant’s Salary. “Change in Control” means the earliest of: the date any one Person, or more than one Person acting as a group (as the term “group” is used in Treasury Regulations section 1.409A-3(i)(5)(v)(B)), acquires ownership of stock of the Company that, together with stock previously held by the acquirer, constitutes more than fifty (50%) percent of the total fair market value or total voting power of Company stock. If any one Person, or more than one Person acting as a group, is considered to own more than fifty (50%) percent of the total fair market value or total voting power of Company stock, the acquisition of additional stock by the same Person or Persons acting as a group does not cause a Change in Control. An increase in the percentage of stock owned by any one Person, or Persons acting as a group, as a result of a transaction in which Company acquires its stock in exchange for property, is treated as an acquisition of stock; 21  Exhibit 10(f)5 (b) the date any one Person, or more than one Person acting as a group (as the term “group” is used in Treasury Regulations section 1.409A-3(i)(5)(v)(B)), acquires (or has acquired during the twelve (12) month period ending on the date of the most recent acquisition by that Person or Persons) ownership of Company stock possessing at least thirty (30%) percent of the total voting power of Company stock; (c) the date a majority of the members of the Company’s board of directors is replaced during any twelve (12) month period by directors whose appointment or election is not endorsed by a majority of the members of the board of directors prior to the date of appointment or election; or (d) the date any one Person, or more than one Person acting as a group (as the term “group” is used in Treasury Regulations section 1.409A-3(i)(5)(v)(B)), acquires (or has acquired during the twelve (12) month period ending on the date of the most recent acquisition by that Person or Persons) assets from the Company that have a total gross fair market value equal to at least forty (40%) percent of the total gross fair market value of all the Company’s assets immediately prior to the acquisition or acquisitions. For this purpose, “gross fair market value” means the value of the corporation’s assets, or the value of the assets being disposed of, without regard to any liabilities associated with these assets. In determining whether a Change in Control occurs, the attribution rules of Code section 318 apply to determine stock ownership. The stock underlying a vested option is treated as owned by the individual who holds the vested option, and the stock underlying an unvested option is not treated as owned by the individual who holds the unvested option. The term “Person” used in this definition means any individual, corporation (including any non-profit corporation), general, limited or limited liability partnership, limited liability company, joint venture, estate, trust, firm, association, organization or other entity or any governmental or quasi-governmental authority, organization, agency or body. “Claimant” shall have the meaning set forth in Section 11.1. “Code” means the Internal Revenue Code of 1986, as it may be amended from time to time. “Company” means ALLETE, Inc., a Minnesota Corporation, and any successor to all, or substantially all, of the Company’s assets or business. “Credited Service” shall have the meaning prescribed in the Retirement Plan A. “Deferrals” means Elective Deferrals and Non-Elective Deferrals. “Disability” or “Disabled” when used with an initial capital letter, means a physical or mental condition in which the Participant is: unable to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment that can be expected to result in death or can be expected to last for a continuous period of not less than twelve (12) months; 22  Exhibit 10(f)5 by reason of any medically determinable physical or mental impairment which can be expected to result in death or can be expected to last for a continuous period of not less than twelve (12) months, receiving income replacement benefits for a period of not less than three (3) months under the Employer’s accident and health plan; determined to be totally disabled by the Social Security Administration; or disabled pursuant to an Employer-sponsored disability insurance arrangement provided that the definition of disability applied under such disability insurance program complies with the foregoing definition of Disability. When the term “disability” (without an initial capital letter) is used in the Plan, it shall have the meaning prescribed in the definition of “Separation from Service.” “Distribution Event” means, with respect to Article 6, a Specified Year, a Separation from Service, death, Disability or the Administrator’s determination regarding the occurrence of an Unforeseeable Emergency and, with respect to Article 8, Retirement, Disability or solely with respect to a Participant who vests after becoming Disabled, the earlier of death or attainment of age 65. “Elective Deferrals” means any portion of a Participant’s Salary, Bonus, Severance Pay, Annual Make-up Award or Other Award that a Participant irrevocably elects to defer. “Eligible Employee” means an Employee in management salary grades SA-SM, who has been notified in writing by the Administrator of eligibility to participate in the Plan. “Eligible Surviving Spouse” shall have the meaning prescribed in Retirement Plan A. “Employee” means a person who is a common-law employee of any Related Company. “Employer(s)” means the Company and any Related Company (now in existence or hereafter formed or acquired) that have been selected by the Administrator to participate in the Plan. “ERISA” means the Employee Retirement Income Security Act of 1974, as it may be amended from time to time. “IRS” means the Internal Revenue Service. “Misconduct” means the occurrence of either or both of the following, as determined in its sole discretion by either the Executive Compensation Committee of the Company’s Board of Directors with respect to Section 16 Officers of the Company, or the Administrator with respect to any other Participant: (a) an act or omission by the Participant involving dishonesty in connection with his or her responsibilities as an employee of the Company; or (b) the Participant’s conviction of, or entry of a plea of nolo contendere to, any felony or a misdemeanor involving moral turpitude, provided that a misdemeanor motor vehicle violation will not constitute a crime of moral turpitude unless it involves driving while 23  Exhibit 10(f)5 impaired within the scope of employment or another serious driving offense committed within the scope of employment. For purposes of clarifying the foregoing definition, Misconduct can occur regardless of whether the Company discovers the Misconduct before or after the Participant’s Separation from Service and regardless of whether the Participant has a Separation from Service on account of the Misconduct. “Non-Elective Deferrals” means 162(m) Deferrals and the Annual Make-up Award credited to the Account of any Participant whose Salary exceeds the Code section 401(a)(17) limit. “Other Award” means an award, other than an Annual Incentive Award or Severance Pay, that a Participant may defer at the Administrator’s discretion. “Participant” means any Eligible Employee (i) who has elected to defer amounts under the Plan, (ii) who is eligible to receive a Retirement Benefit or (iii) whose compensation, or a portion thereof, was deferred as a Non-Elective Deferral. “Plan” means SERP II. “Plan Year” means a period beginning on January 1 of each calendar year and continuing through December 31 of such calendar year. “Related Company” means the Company and all persons with whom the Company would be considered a single employer under Code section 414(b) (employees of controlled group of corporations), and all persons with whom such person would be considered a single employer under Code section 414(c) (employees of partnerships, proprietorships, etc., under common control); provided that in applying Code sections 1563(a)(1), (2), and (3) for purposes of determining a controlled group of corporations under Code section 414(b), the language “at least 50 percent” is used instead of “at least 80 percent” each place it appears in Code sections 1563(a)(1), (2), and (3), and in applying Treasury Regulations section 1.414(c)-2 for purposes of determining trades or businesses (whether or not incorporated) that are under common control for purposes of Code section 414(c), “at least 50 percent” is used instead of “at least 80 percent” each place it appears in Treasury Regulations section 1.414(c)-2. “Retirement” means Separation from Service, for reasons other than death, on or after attaining both 50 years of age and 10 years of Vesting Service. “Retirement Benefit” means the benefit payable pursuant to Article 8. “Retirement Plans” mean the Minnesota Power and Affiliated Companies Retirement Plan A and Minnesota Power and Affiliated Companies Retirement Plan B, as amended from time to time. “Retirement Savings and Stock Ownership Plan” or “RSOP” means the Minnesota Power and Affiliated Companies Retirement Savings and Stock Ownership Plan, as amended from time to time. “Salary” means the Participant’s earnings during a calendar year, before any reduction pursuant to Code sections 125, 132(f)(4), or 401(k) and this Plan.

A Participant shall not be considered to separate from service during a bona fide leave of absence for less than six (6) months or longer if the Participant retains a right to reemployment with any Related Company by contract or statute. With respect to disability leave, a Participant shall not be considered to separate from service for 29 months unless the Participant otherwise terminates employment or is terminated by all Related Companies. For purposes of determining whether a Separation from Service has occurred on account of a disability, a Participant shall be disabled if the Participant is suffering from any medically determinable physical or mental impairment resulting in the Participant’s inability to perform the duties of his position or any substantially similar position, if such impairment can be expected to result in death or can be expected to last for a continuous period of 6 months. “SERP II” means the ALLETE and Affiliated Companies Supplemental Executive Retirement Plan II, as amended from time to time. “Severance Pay” means the cash payment(s) to a Participant payable in connection with his Separation from Service in accordance with the terms of a severance arrangement that is the subject of bona fide, arm’s length negotiations between a Related Company and the Participant at the time of the Separation from Service. “Specified Year” means a calendar year during which a Participant has elected to receive a distribution of Elective Deferrals. “Specified Employee” means an Employee who is subject to the six-month delay rule described in Code section 409A(2) (B)(i).

Further terms and conditions of the Grant are set forth in Annex A hereto, which is an integral part of this Grant. Any term, provision or condition applicable to the Restricted Stock Units set forth in the Plan and not set forth herein is hereby incorporated by reference. To the extent any provision hereof is inconsistent with a Plan provision, the Plan provision will govern. YOU SHOULD CAREFULLY READ AND REVIEW THE TERMS AND CONDITIONS SET FORTH IN THIS GRANT, INCLUDING ANNEX A HERETO, WHICH CONTAINS IMPORTANT INFORMATION, INCLUDING MANDATORY CLAIMS AND ARBITRATION PROCEDURES. You will be deemed to have accepted this Grant on the Date of Grant, and all its associated terms and conditions, including the mandatory claims and arbitration procedures set forth in Annex A, unless you notify the Company of your non-acceptance of the Grant by contacting the Director – Human Resources, in writing within sixty (60) days of the Date of Grant. IN WITNESS WHEREOF, ALLETE has caused this Grant to be executed by its Chair, President and Chief Executive Officer as of the date and year first above written. ALLETE By: Chair, President & CEO Attachment: Annex A Exhibit 10(i)17 ANNEX A TO ALLETE EXECUTIVE LONG-TERM INCENTIVE COMPENSATION PLAN RESTRICTED STOCK UNIT GRANT The grant of restricted stock units (each, a “RSU”) under the ALLETE Executive Long-Term Incentive Compensation Plan (the “Plan”), evidenced by the Grant to which this is annexed, is subject to the following additional terms and conditions: 1. Form and Timing of Payment. Subject to the provisions hereof, each RSU will be paid in the form of one share of ALLETE common stock (each, a “Share”), plus accrued Dividend Equivalents. Shares will be deposited into your ALLETE Invest Direct plan account. Except as otherwise provided in sections 3 and 4, below, payment will be made during the period ending sixty days after the end of the vesting period; provided, however, the Participant will not be permitted, directly or indirectly, to designate the taxable year of the distribution. Payment will be subject to withholding Shares equal in value to the minimum amount of tax required to be withheld by law. 2. Dividend Equivalents. You will receive Dividend Equivalents in connection with the RSUs granted. Dividend Equivalents will be calculated and credited to you at the time the underlying RSUs are paid. Dividend Equivalents will be in the form of additional RSUs, which will be added to the number of RSUs subject to the grant, and will equal the number of Shares (including fractional Shares) that could have been purchased on applicable dividend payment dates, based on the closing ALLETE common stock price as reported in the consolidated transaction reporting system on that date, with cash dividends that would have been paid on the underlying RSUs, if such RSUs were Shares. Dividend Equivalents will only become payable if and to the extent the underlying RSUs vest and become payable. 3. Payment Upon Retirement, Death or Disability; Forfeiture Upon Other Termination of Employment, Default on Certain Agreements or Unsatisfactory Job Performance. 3.1 Subject to Section 3.4 below, if during the vesting period you (i) Retire, (ii) die while employed by a Related Company, or (iii) become Disabled, a portion of the unvested RSUs subject to the Grant will vest and be paid to you (or your beneficiary or estate) during the period ending sixty days after such event; provided, however, you will not be permitted, directly or indirectly, to designate the taxable year of the distribution. Except as otherwise provided in Section 4, payment pursuant to this Section 3.1 will be prorated, after giving effect to accumulated Dividend Equivalents, based on the number of whole calendar months within the vesting period that had elapsed as of the date of Retirement, death or Disability in relation to the number of calendar months in the vesting period. For purposes of this calculation, you will be credited with a whole month if you were employed on the 15 of the month. th 3.2 Except as otherwise provided in Section 4, if during the vesting period or prior to payment of all RSUs you have a Separation from Service for any reason other than those specified in Section 3.1 above, all unvested or unpaid RSUs subject to the Grant (and related Dividend Equivalents) will be forfeited on the date of such Separation from Service. 3.3 If during the vesting period or prior to payment of all RSUs you are demoted, you default on any written agreement with a Related Company related to a restrictive employment covenant (such as confidentiality, non-disclosure, non-competition, non-solicitation, or the like), or if ALLETE determines, in its sole discretion, that your job performance is unsatisfactory, ALLETE may cancel or amend your 2 Exhibit 10(i)17 grant relating to any unpaid RSUs, resulting in the forfeiture of some portion or all of your unpaid RSUs (and related Dividend Equivalents). 3.4 Notwithstanding anything herein to the contrary, if you become entitled to a payment of the RSUs by reason of your Retirement and if you are a Specified Employee on the date of such Retirement, payment shall not be made until the earlier of: (i) the expiration of the six-month period beginning on the date of your Retirement, or (ii) the date of your death. The payment to which a Specified Employee would otherwise be entitled during this six-month period shall be paid, together with Dividend Equivalents that have accrued during this six-month delay, during the seventh month following the date of the Participant’s Retirement, or, if earlier, the date of the Participant’s death. 4. Change in Control. Upon a Change in Control, unless the Committee provides otherwise prior to the Change in Control, outstanding unvested RSUs shall be prorated (as described below) and such prorated RSUs shall immediately vest and be payable to you during the period ending sixty days after the Change in Control. The RSUs will not be subject to proration and immediately vest, however, if and to the extent that the Grant is, in connection with the Change in Control, fully assumed by the successor corporation or parent thereof; in such case, the RSUs shall be prorated and immediately vest upon your termination of employment by the successor corporation for reasons other than cause within 18 months following the Change in Control and be payable to the Participant during the period ending sixty days after the termination of employment. Any payment on account of or in connection with a Change in Control will be prorated, after giving effect to the accumulation of Dividend Equivalents, based on the number of whole calendar months within the vesting period that had elapsed as of the date of the Change in Control or termination of employment, as applicable, in relation to the number of calendar months in the vesting period. For purposes of this calculation, you will be credited with a whole month if you were employed on the 15 of the month. In no event will you be permitted, directly or indirectly, to designate the taxable year of the distribution on account of or in connection with a Change in Control. th 5. Compensation Recovery Policy. The Grant is subject to the terms of any compensation recovery policy or policies established by ALLETE as may be amended from time to time (“Compensation Recovery Policy”). ALLETE hereby incorporates into the Grant the terms of the Compensation Recovery Policy. 6. Section 409A Compliance. This Grant is intended to comply with Section 409A or an exemption thereunder, and, accordingly, to the maximum extent permitted, the Plan and the Grant shall be interpreted and administered in compliance therewith. Notwithstanding any other provision of the Grant, payments provided pursuant to the Grant may only be made upon an event and in a manner that complies with Section 409A or an applicable exemption. Any payments pursuant to the Grant that may be excluded from Section 409A as a short-term deferral shall be excluded from Section 409A to the maximum extent possible. To the extent that any provision of the Grant would cause a conflict with the requirements of Section 409A or would cause the administration of the Grant to fail to satisfy Section 409A, such provision shall be deemed null and void to the extent permitted by applicable law. Nothing herein shall be construed as a guarantee of any particular tax treatment. ALLETE makes no representation that the Grant complies with Section 409A and in no event shall ALLETE be liable for the payment of any taxes and penalties that you may incur under Section 409A. 7.

General Procedures. 4 Exhibit 10(i)17 1. Arbitration Rules. The arbitration hearing will be conducted under the AAA Commercial Arbitration Rules (as amended or revised from time to time by AAA) (hereinafter the “AAA Rules”), before one AAA arbitrator who is from the Large, Complex Case Panel and who has experience with matters involving executive compensation and equity compensation plans. The AAA Rules and the terms and procedures set forth here may conflict on certain issues. To the extent that the procedures set forth here conflict with the AAA Rules, the procedures set forth here shall control and be applied by the arbitrator. Notwithstanding the amount of the claim, the Procedures for Large, Complex Commercial Disputes shall not apply. 2. Substantive Law. The arbitrator shall apply the substantive law (and the laws of remedies, if applicable), of Minnesota or federal law, or both, depending upon the claim. Except to the extent required by applicable law, the Claimant shall keep any arbitration decision or award strictly confidential and not disclose to anyone other than his or her spouse, attorney, or tax advisor. 3. Authority. The arbitrator shall have jurisdiction to hear and rule on prehearing disputes and is authorized to hold prehearing conferences by telephone or in person as the arbitrator deems necessary. The arbitrator will have the authority to hear a motion to dismiss and/or a motion for summary judgment by any party and in doing so shall apply the standards governing such motions under the Federal Rules of Civil Procedure. 4. Pre-Hearing Procedures. Each party may take the deposition of not more than one individual and the expert witness, if any, designated by another party. Each party will have the right to subpoena witnesses in accordance with the Federal Arbitration Act, Title 9 of the United States Code. Additional discovery may be had only if the arbitrator so orders, upon a showing of substantial need. 5. Fees and Costs. Administrative arbitration fees and arbitrator compensation shall be borne equally by the parties, and each party shall be responsible for its own attorney’s fees, if any; provided, however, that the Committee will authorize payment by the Company of all administrative arbitration fees, arbitrator compensation and attorney’s fees if the Committee concludes that a Claimant has substantially prevailed on his or her claims. Unless prohibited by statute, the arbitrator shall assess attorney’s fees against a party upon a showing that such party’s claim, defense or position is frivolous, or unreasonable, or factually groundless. If either party pursues a claim by any means other than those set forth in this Article, the responding party shall be entitled to dismissal of such action, and the recovery of all costs and attorney’s fees and losses related to such action, unless prohibited by statute. a. Interstate Commerce and the Federal Arbitration Act. The Company is involved in transactions involving interstate commerce, and the employee’s employment with the Company involves such commerce. Therefore, the Federal Arbitration Act, Title 9 of the United States Code, will govern the interpretation, enforcement, and all judicial proceedings regarding the arbitration procedures in this Section. 8. Ratification of Actions. By receiving the Grant or other benefit under the Plan, you and each person claiming under or through you shall be conclusively deemed to have indicated your acceptance and ratification of, and consent to, any action taken under the Plan or the Grant by ALLETE, the Board, or the Committee. 9. No Impact on Other Benefits. The Grant or payment on account thereof shall not be taken into account in determining any benefits under any severance, retirement, welfare, insurance or other benefit 5 Exhibit 10(i)17 plan of ALLETE or any affiliate except to the extent otherwise expressly provided in writing in such other plan or an agreement thereunder. 10. Notices. Any notice hereunder to ALLETE shall be addressed to ALLETE, 30 West Superior Street, Duluth, Minnesota 55802, Attention: Director – Human Resources, and any notice hereunder to you shall be directed to your address as indicated by ALLETE’s records, subject to the right of either party to designate at any time hereafter in writing some other address. 11. Governing Law and Severability. To the extent not preempted by the Federal law, the Grant will be governed by and construed in accordance with the laws of the State of Minnesota, without regard to its conflicts of law provisions. In the event any provision of the Grant shall be held illegal or invalid for any reason, the illegality or invalidity shall not affect the remaining parts of the Grant, and the Grant shall be construed and enforced as if the illegal or invalid provision had not been included. 12. Definitions. Capitalized terms not otherwise defined herein shall have the meanings given them in the Plan. The following definitions apply to the Grant and this Annex A: 12.1 “Claims Administrator” means ALLETE’s Chief Executive Officer, unless the claimant is (or is acting on behalf of) an ALLETE executive officer (within the meaning of Exchange Act Rule 3b-7), in which case the Claims Administrator is the Executive Compensation Committee of the Board of Directors. 12.2 “Change in Control” means the earliest of: i. ii. iii. iv. the date any one Person, or more than one Person acting as a group (as the term “group” is used in Treasury Regulations section 1.409A-3(i)(5)(v)(B)), acquires ownership of stock of the Company that, together with stock previously held by the acquirer, constitutes more than fifty (50%) percent of the total fair market value or total voting power of Company stock. If any one Person, or more than one Person acting as a group, is considered to own more than fifty (50%) percent of the total fair market value or total voting power of Company stock, the acquisition of additional stock by the same Person or Persons acting as a group does not cause a Change in Control. An increase in the percentage of stock owned by any one Person, or Persons acting as a group, as a result of a transaction in which Company acquires its stock in exchange for property, is treated as an acquisition of stock; the date any one Person, or more than one Person acting as a group (as the term “group” is used in Treasury Regulations section 1.409A-3(i)(5)(v)(B)), acquires (or has acquired during the twelve (12) month period ending on the date of the most recent acquisition by that Person or Persons) ownership of Company stock possessing at least thirty (30%) percent of the total voting power of Company stock; the date a majority of the members of the Company’s board of directors is replaced during any twelve (12) month period by directors whose appointment or election is not endorsed by a majority of the members of the board of directors prior to the date of appointment or election; or the date any one Person, or more than one Person acting as a group (as the term “group” is used in Treasury Regulations section 1.409A-3(i)(5)(v)(B)), acquires (or has acquired during the twelve (12) month period ending on the date of the most recent acquisition by that Person or Persons) assets from the Company that have a total gross fair market value equal to at least forty (40%) percent of the total gross fair market value of all the Company’s assets immediately prior to the acquisition or acquisitions. For this purpose, “gross fair market value” means the value of the 6 Exhibit 10(i)17 corporation’s assets, or the value of the assets being disposed of, without regard to any liabilities associated with these assets. In determining whether a Change in Control occurs, the attribution rules of Code section 318 apply to determine stock ownership. The stock underlying a vested option is treated as owned by the individual who holds the vested option, and the stock underlying an unvested option is not treated as owned by the individual who holds the unvested option. The term “Person” used in this definition means any individual, corporation (including any non-profit corporation), general, limited or limited liability partnership, limited liability company, joint venture, estate, trust, firm, association, organization or other entity or any governmental or quasi-governmental authority, organization, agency or body. 12.3 “Code” means the Internal Revenue Code of 1986, as it may be amended from time to time. 12.4 “Disability” or “Disabled” means a physical or mental condition in which the Participant is: i. ii. iii. iv. unable to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment that can be expected to result in death or can be expected to last for a continuous period of not less than twelve (12) months; by reason of any medically determinable physical or mental impairment which can be expected to result in death or can be expected to last for a continuous period of not less than twelve (12) months, receiving income replacement benefits for a period of not less than three (3) months under the Employer’s accident and health plan; determined to be totally disabled by the Social Security Administration; or disabled pursuant to an Employer-sponsored disability insurance arrangement provided that the definition of disability applied under such disability insurance program complies with the foregoing definition of Disability. 12.5 “Related Company” means the ALLETE, Inc. and all persons with whom the ALLETE, Inc. would be considered a single employer under Code section 414(b) (employees of controlled group of corporations), and all persons with whom such person would be considered a single employer under Code section 414(c) (employees of partnerships, proprietorships, etc., under common control); provided that in applying Code sections 1563(a)(1), (2), and (3) for purposes of determining a controlled group of corporations under Code section 414(b), the language “at least 50 percent” is used instead of “at least 80 percent” each place it appears in Code sections 1563(a)(1), (2), and (3), and in applying Treasury Regulations section 1.414(c)-2 for purposes of determining trades or businesses (whether or not incorporated) that are under common control for purposes of Code section 414(c), “at least 50 percent” is used instead of “at least 80 percent” each place it appears in Treasury Regulations section 1.414(c)-2. 12.6 “Retirement” or “Retires” means Separation from Service, for reasons other than death or Disability, on or after attaining normal retirement age or early retirement age as defined in the most applicable qualified retirement plan sponsored by the Related Company that employed the Participant immediately preceding the Separation from Service, without regard to whether the Participant is a participant in such plan, or if the employer Related Company does not sponsor such retirement plan, on or after attaining Normal Retirement Age or Early Retirement Age as defined in the ALLETE and Affiliated Companies Retirement Plan A, without regard to whether the Participant is a participant under the ALLETE and Affiliated Companies Retirement Plan A. 12.7 “Section 409A” means Section 409A of the Code and Treasury Regulations section 1.409A-1 et seq., as they both may be amended from time to time, or other guidance issued by the Treasury Department and Internal Revenue Service thereunder. 7 Exhibit 10(i)17 12.8 “Separation from Service” means that the Participant terminates employment within the meaning of Treasury Regulations section 1.409A-1(h) and other applicable guidance with all Related Companies. Whether a termination of employment has occurred is determined under the facts and circumstances, and a termination of employment shall occur if all Related Companies and the Participant reasonably anticipate that no further services shall be performed after a certain date or that the level of bona fide services the Participant shall perform after such date (as an employee or an independent contractor) shall permanently decrease to no more than 20 percent of the average level of bona fide services performed (whether as an employee or an independent contractor) over the immediately preceding 36-month period (or the full period of services to the Related Companies if the Participant has been providing services to the Related Companies less than 36 months). A Participant shall not be considered to separate from service during a bona fide leave of absence for less than six (6) months or longer if the Participant retains a right to reemployment with any Related Company by contract or statute. With respect to disability leave, a Participant shall not be considered to separate from service for 29 months unless the Participant otherwise terminates employment or is terminated by all Related Companies. 12.9 “Specified Employee” means an Participant who is subject to the six-month delay rule described in Code section 409A(2)(B)(i), determined in accordance with guidelines adopted by the Board from time to time as permitted by Section 409A of the Code and Treasury Regulations section 1.409A-1 et seq., as they both may be amended from time to time, and other guidance issued by the Treasury Department and Internal Revenue Service thereunder. 8 Exhibit 10(i)18 ALLETE EXECUTIVE LONG-TERM INCENTIVE COMPENSATION PLAN PERFORMANCE SHARE GRANT [Effective 2022] [Eligible Executive Employees] Name In accordance with the terms of ALLETE’s Executive Long-Term Incentive Compensation Plan, as amended (the "Plan"), and as determined by and through the Executive Compensation Committee of ALLETE’s Board of Directors, ALLETE hereby grants to you (the "Participant") Performance Shares, as set forth below, subject to the terms and conditions set forth in this Grant, including Annex A and Annex B hereto and all documents incorporated herein by reference: Number of Performance Shares Granted: # [#]–Total Shareholder Return Metric # [#]–Compound Annual Growth Rate Metric # Date of Grant: February 1, 2022 Performance Period: January 1, 2022 through December 31, 2024 Performance Goals: See Annex B This Grant is made in accordance with the Plan. Further terms and conditions of the Grant are set forth in Annex A hereto and Performance Goals are set forth in Annex B hereto, both of which are integral parts of this Grant. Any term, provision or condition applicable to the Performance Shares set forth in the Plan and not set forth herein is hereby incorporated by reference. To the extent any provision hereof is inconsistent with a Plan provision, the Plan provision will govern. YOU SHOULD CAREFULLY READ AND REVIEW THE TERMS AND CONDITIONS SET FORTH IN THIS GRANT, INCLUDING ANNEX A HERETO, WHICH CONTAINS IMPORTANT INFORMATION, INCLUDING MANDATORY CLAIMS AND ARBITRATION PROCEDURES. You will be deemed to have accepted this Grant on the Date of Grant and all its associated terms and conditions, including the mandatory claims and arbitration procedures set forth in Annex A, unless you notify the Company of your non-acceptance of the Grant by contacting the Director – Human Resources, in writing within sixty (60) days of the Date of Grant. IN WITNESS WHEREOF, ALLETE has caused this Grant to be executed by its Chair, President and Chief Executive Officer as of the date and year first above written. ALLETE By: Chair, President & CEO Attachments: Annex A and Annex B Exhibit 10(i)18 ANNEX A TO ALLETE EXECUTIVE LONG-TERM INCENTIVE COMPENSATION PLAN PERFORMANCE SHARE GRANT The Performance Share Grant to which this is annexed is subject to the following additional terms and conditions: 1. Dividend Equivalents. You will receive Dividend Equivalents with respect to Performance Shares that are earned and payable. Dividend Equivalents are calculated and credited to you after the Performance Period has ended. The Dividend Equivalents will be in the form of additional Performance Shares, which will be added to the number of Performance Shares earned, and will equal the number of Shares (including fractional Shares) that could have been purchased on applicable dividend payment dates, based on the closing ALLETE common stock price as reported in the consolidated transaction reporting system on that date, with cash dividends that would have been paid on underlying Performance Shares, if such Performance Shares were Shares. Dividend Equivalents will only become payable if and to the extent the underlying Performance Shares are earned and become payable. 2. Satisfaction of Goals. Performance Shares remain unearned unless and until Performance Goals are achieved. After the Performance Period has ended, the Executive Compensation Committee (the “Committee”) will determine the extent to which the Performance Goals have been met. You will not earn any Performance Shares if the threshold performance level has not been met. Subject to the provisions of Section 4 below and to provisions in the Plan for change in control, Performance Shares will be earned as follows: If the threshold level has been met, you will have earned 50% of the Performance Shares (as increased by the Dividend Equivalents). If the target level has been met, you will have earned 100% of the Performance Shares (as increased by the Dividend Equivalents). If the superior level has been met, you will have earned 200% of the Performance Shares (as increased by the Dividend Equivalents). Straight line interpolation will be used to determine earned awards based on achievement of goals between the threshold, target and superior levels. 3. Payment. Subject to the provisions of Section 4 below and to provisions in the Plan for Change in Control, Performance Shares (as increased by the Dividend Equivalents) shall be paid in full after the Committee has determined the extent to which Performance Goals have been met and within two and one half months after the end of the Performance Period. Payment shall be made, after withholding Performance Shares in an amount equal in value to the minimum amount of tax required to be withheld by law, by depositing ALLETE common stock into your Invest Direct account. Performance Share awards shall not vest until paid. 4. Payment Upon Death, Retirement or Disability; Forfeiture of Unvested Performance Shares Upon Demotion, Unsatisfactory Job Performance, Default on Certain Agreements or Other Separation from Service. 4.1 If during a Performance Period you (i) Retire, (ii) die while employed by a Related Company, or (iii) become Disabled, you (or your beneficiary or estate) will receive a payment of any Performance Shares (as increased by the Dividend Equivalents) after the end of the Performance Period in accordance with Section 3 above. The payment shall be prorated based upon the number of whole calendar months within the Performance Period which had elapsed as of the date of death, Retirement or Disability in relation to the number of calendar months in the full Performance Period. A whole month is counted in the calculation if you were in the position as of the 15 of the month. th Exhibit 10(i)15 4.2 If after the end of a Performance Period, but before any or all Performance Shares have been paid, you Retire, die or become Disabled, you (or your beneficiary or estate) will be entitled to full payout of all earned Performance Shares (as increased by the Dividend Equivalents) in accordance with Section 3 above. 4.3 If, prior to payment of all Performance Shares, you are demoted, you default on any written agreement with a Related Company related to a restrictive employment covenant (such as confidentiality, non-disclosure, non-competition, non- solicitation, or the like) or ALLETE determines, in its sole discretion, that your job performance is unsatisfactory, ALLETE reserves the right to cancel or amend your grant relating to any unpaid Performance Shares, with the result that some portion or all of your unpaid Performance Shares (and related Dividend Equivalents) will be forfeited. 4.4 If you have a Separation from Service for any reason other than those specified in subsection 4.1 above, all Performance Shares (and related Dividend Equivalents), to the extent not yet paid, shall be forfeited on the date of such Separation from Service, except as otherwise provided by the Committee. 5. Compensation Recovery Policy. The Grant is subject to the terms of any compensation recovery policy or policies established by ALLETE as may be amended from time to time (“Compensation Recovery Policy”). ALLETE hereby incorporates into the Grant the terms of the Compensation Recovery Policy. 6. Section 409A Compliance. This Grant is intended to comply with Section 409A of the Code (“Section 409A”) or an exemption thereunder, and, accordingly, to the maximum extent permitted, the Plan and the Grant shall be interpreted and administered in compliance therewith. Notwithstanding any other provision of the Grant, payments provided pursuant to the Grant may only be made upon an event and in a manner that complies with Section 409A or an applicable exemption. Any payments pursuant to the Grant that may be excluded from Section 409A as a short-term deferral shall be excluded from Section 409A to the maximum extent possible. To the extent that any provision of the Grant would cause a conflict with the requirements of Section 409A or would cause the administration of the Grant to fail to satisfy Section 409A, such provision shall be deemed null and void to the extent permitted by applicable law. Nothing herein shall be construed as a guarantee of any particular tax treatment. ALLETE makes no representation that the Grant complies with Section 409A and in no event shall ALLETE be liable for the payment of any taxes and penalties that you may incur under Section 409A. 7. Claims Procedure and Arbitration. The Grant is subject to the following claims procedures: 7.1 Mandatory Claims Procedures. If you or any person acting on your behalf (the “Claimant”) has any claim or dispute related in any way to the Grant or to the Plan, the Claimant must follow these claims procedures.

Enforceability. Judgment upon any award entered by an arbitrator may be entered in any court having jurisdiction over the parties. f. Waiver of Class, Collective, and Representative Actions. Any claim shall be heard without consolidation of such claims with any other person or entity.

Standard of Review. Any decision of an arbitrator on a claim shall be limited to determining whether the Claims Administrator’s decision or action was arbitrary or capricious or was unlawful. The arbitrator shall adhere to and apply the deferential standard of review set out in Conkright v. Frommert, 130 S. Ct. 1640 (2010), Metropolitan Life Insurance Co. v. Glenn, 554 U.S. 105 (2008), and Firestone Tire and Rubber Company v. Bruch, 489 U.S. 101 (1989), and shall accord due deference to the determinations, interpretations, and construction of the Plan document by the Claims Administrator. h. General Procedures. Arbitration Rules. The arbitration hearing will be conducted under the AAA Commercial Arbitration Rules (as 1. amended or revised from time to time by AAA) (hereinafter the “AAA Rules”), before one AAA arbitrator who is from the Large, Complex Case Panel and who has experience with matters involving executive compensation and equity compensation plans. The AAA Rules and the terms and procedures set forth here may conflict on certain issues. To the extent that the procedures set forth here conflict with the AAA Rules, the procedures set forth here shall control and be applied by the arbitrator. Notwithstanding the amount of the claim, the Procedures for Large, Complex Commercial Disputes shall not apply. 3 Exhibit 10(i)15 2. Substantive Law. The arbitrator shall apply the substantive law (and the laws of remedies, if applicable), of Minnesota or federal law, or both, depending upon the claim. Except to the extent required by applicable law, the Claimant shall keep any arbitration decision or award strictly confidential and not disclose to anyone other than his or her spouse, attorney, or tax advisor. 3.

If ALLETE’s TSR ranking is at the 50 percentile among the peer group (target performance), 100% of the weighted Performance Share Grant will be earned. If ALLETE’s TSR ranking is at the 30 percentile (threshold performance), 50% of the weighted Performance Share Grant will be earned. If TSR ranking is below threshold, no weighted Performance Shares will be earned. Straight-line interpolation will be used to determine earned awards based on the TSR ranking between threshold, target and superior. th th Peer Group: The integrated utility companies comprising Edison Electric Institute (EEI) Stock Index as of December 31, 2024 that have been in the EEI Stock Index for at least three years as of December 31, 2024 will constitute the peer group used to determine actual payout results. The table below lists the EEI Stock Index as of December 31, 2021, based on published information available as of that date: Alliant Energy Corporation Ameren Corporation American Electric Power Company Avangrid, Inc. Avista Corporation Black Hills Corporation CenterPoint Energy, Inc. CMS Energy Corporation Consolidated Edison, Inc. Dominion Energy, Inc. DTE Energy Company Duke Energy Corporation Edison International Entergy Corporation Evergy Inc. Eversource Energy Exelon Corporation FirstEnergy Corporation Hawaiian Electric Industries, Inc.

Otter Tail Corporation PG&E Corporation Pinnacle West Capital Corporation PNM Resources, Inc. Portland General Electric Company PPL Corporation Public Service Enterprise Group, Inc. Sempra Energy The Southern Company Unitil Corporation WEC Energy Group, Inc. Xcel Energy, Inc. Any Company that is no longer included in the EEI Stock Index as of December 31, 2024 due to corporate restructuring during the performance period (e.g., mergers, acquisitions, divestitures, spin-offs, etc.) will be excluded from the results calculation entirely. If a corporate restructuring during the performance period results in a company remaining in the EEI Stock Index following the transaction (and thus not Exhibit 10(i)18 being excluded from the results calculation entirely), from the point of the transaction forward, the results calculation will track only the entity that remains in the EEI Stock Index and ignore other entities, regardless of whether such other entities are publicly traded. Performance Share Award (CAGR metric): CAGR will be calculated by using the baseline pro forma Earnings per Share (EPS) for the year ending December 31 of the year prior to the beginning of the three-year performance period and the pro forma EPS at the end of the three-year performance period. Achievement will be weighted on CAGR performance in accordance with the following table: Compound Annual Growth Rate Superior [ ]% Target [ ]% Threshold [ ]% Payout Percentage (% of Target Award) 200% 100% 50% If CAGR percentage result is below threshold, no weighted Performance Shares will be earned. Straight-line interpolation will be used to determine earned awards based on the CAGR percentage result between threshold, target and superior. ALLETE, INC.

(NYSE: ALE) today reported 2021 earnings of $3.23 per share on net income of $169.2 million and operating revenue of $1.4 billion. Reported results from 2020 were $3.35 per share on net income of $174.2 million and operating revenue of $1.2 billion. Earnings in 2021 reflect an approximately 16 cent gain recorded in the fourth quarter of 2021 for the sale of a portion of the Nemadji Trail Energy Center by South Shore Energy, ALLETE’s non-rate regulated, Wisconsin subsidiary. This positive impact was partially offset by a 10 cent per share, negative impact related to ALLETE Clean Energy’s Diamond Spring wind energy facility due to the February extreme winter storm event. Additionally, net income in 2021 included a 7 cent per share charge resulting from the Minnesota Public Utilities Commission’s decision to order refunds in Minnesota Power’s fuel adjustment clause filing covering the period July 2018 through December 2019. “I am pleased with the Company’s 2021 financial results and strategic clean energy positioning as we launch 2022 from a position of strength,” said ALLETE Chair, President and CEO Bethany Owen, “ALLETE’s Sustainability in Action strategy will continue to capitalize on demand for clean energy, providing value to our customers, our communities and our investors, as well as opportunities for our employees.” ALLETE’s Regulated Operations segment, which includes Minnesota Power, Superior Water, Light and Power and the Company’s investment in the American Transmission Co., recorded net income of $129.1 million, compared to $136.3 million in 2020. Earnings reflect lower net income at Minnesota Power primarily due to: lower margins from the expiration of a power sales contract in 2020; higher operating and maintenance, property tax and depreciation expenses; and the reserve for refunds in Minnesota Power’s fuel adjustment clause filing. These negative impacts were partially offset by increased earnings related to the Great Northern Transmission Line; and higher kilowatt-hour sales to retail and municipal customers. Net income in 2020 also included the rate case resolution impact of $8.3 million after-tax. ALLETE Clean Energy recorded 2021 net income of $26.3 million compared to $29.9 million in 2020. Net income in 2021 included the impact related to ALLETE Clean Energy’s Diamond Spring wind energy facility due to an extreme winter storm event in the southwest United States in February 2021 as well as lower wind resources at other wind energy facilities. These negative impacts were partially offset by expense management efforts. Corporate and Other businesses, which include BNI Energy and ALLETE Properties, recorded net income of $13.8 million in 2021 compared to net income of $8 million in 2020. Net income in 2021 included South Shore Energy’s sale of a portion of its interest in NTEC to Basin Electric Cooperative which resulted in the recognition of an approximately $8.5 million after-tax gain related to prior development costs and risks incurred, higher earnings from our investment in Nobles 2 which commenced operations in December 2020 and higher net income from land sales at ALLETE Properties. These increases were partially offset by higher expenses.

ALE-CORP The statements contained in this release and statements that ALLETE may make orally in connection with this release that are not historical facts, are forward-looking statements. Actual results may differ materially from those projected in the forward-looking statements. These forward-looking statements involve risks and uncertainties and investors are directed to the risks discussed in documents filed by ALLETE with the Securities and Exchange Commission. ALLETE's press releases and other communications may include certain non-Generally Accepted Accounting Principles (GAAP) financial measures. A "non-GAAP financial measure" is defined as a numerical measure of a company's financial performance, financial position or cash flows that excludes (or includes) amounts that are included in (or excluded from) the most directly comparable measure calculated and presented in accordance with GAAP in the company's financial statements. Non-GAAP financial measures utilized by the Company include presentations of earnings (loss) per share. ALLETE's management believes that these non-GAAP financial measures provide useful information to investors by removing the effect of variances in GAAP reported results of operations that are not indicative of changes in the fundamental earnings power of the Company's operations. Management believes that the presentation of the non-GAAP financial measures is appropriate and enables investors and analysts to more accurately compare the company's ongoing financial performance over the periods presented.
