Not-for-profit, member-owned WPPI measures success by the satisfaction of our members. Delivering value is how we earn that success. In turn, our members measure success by how well they meet the needs of their customers and invest in the long-term vitality of their communities. That shared focus continues to guide our work. A Proven Model, Thoughtfully Applied The joint action model that defines WPPI has endured because it is designed for long-term responsibility. For more than four decades, members have governed, directed and invested in this organization together. That continuity provides stability, while thoughtful application of the model enables responsiveness to changing industry conditions and community expectations. In 2025, WPPI continued to carry out this responsibility with intention. Long-term planning, portfolio diversity and careful decision-making remained central to how the membership fulfilled its shared obligations. These efforts reflect stewardship over time, rather than a focus on any single year or outcome. Strong Leadership WPPI’s strength is grounded in the active role members play in shaping the organization. Participation in governance, committee leadership and strategic discussion remains high, reflecting confidence in the joint action model and commitment to its continued success. Member engagement also extends beyond WPPI. Local leaders serve in national public power roles, including on the American Public Power Association’s Policy Makers Council. Their involvement helps ensure that local perspectives inform broader policy conversations affecting public power communities across the country. Supporting Members’ Daily Work Alongside power supply and advocacy, joint action shows up in frequent, practical ways through shared programs and services that support members’ daily operations. These shared programs and services position WPPI staff and technology to collaborate and work directly with member utilities. Through local distribution system support, customer-facing tools, operational guidance and technical systems, members interact with WPPI programs and services many times each day. Those ongoing relationships, responsiveness and focus on local needs are key drivers of members’ strong satisfaction with WPPI. In 2025, this work included significant emphasis on training and education, supporting members as they build industry, technical and customer service expertise amid ongoing change. From The Chair And The President & Ceo 4 2025 ANNUAL REPORT WPPI ENERGY Page 5 of 63 Local Impact While WPPI operates at a scale reflecting the combined strength of 51 utilities, its purpose remains local. Through joint action, WPPI supports member investments in education, economic development, customer engagement and other local priorities. Decisions about how those resources are used remain firmly in local hands, reflecting the needs and values of each community served. For the Long Term WPPI’s role is to manage shared resources, programs and services for members consistently and transparently. In 2025, this included continued attention to long-term planning, transmission ownership and a diverse power supply portfolio that supports competitiveness and predictability over time. The progress we made during the year reflects an ongoing commitment to fulfilling responsibilities, within a framework shaped and governed by the membership. This approach allows WPPI to remain steady and adaptable as the electric industry continues to evolve. Strength You Can Rely On The WPPI membership’s enduring strength does not rest on any single year’s accomplishment or result. It rests on local ownership, active member leadership, and a shared long-term commitment. This is the strength members have built together and it is strength they can continue to rely on as they serve their communities today and into the future.

For WPPI Energy and its members, joint action is how those principles are strengthened and sustained. By working together, WPPI member utilities share resources and expertise in ways that would not be possible alone. This collaborative model supports reliable power supply, disciplined cost management and thoughtful planning that keeps community needs at the center of every decision. In 2025, that approach continues to deliver measurable value. Member utilities rely on WPPI’s long-term power supply strategy, coordinated planning and shared services to navigate an increasingly complex energy landscape. Clear, timely communication and strong staff support help members make confident, informed decisions for their communities. Satisfied, Engaged Members That value is reflected directly in member feedback. In the most recent member satisfaction survey, WPPI received a 97 percent satisfaction rating from member leaders, the highest score in the organization’s history . Member leaders cited the importance of clear communication, the benefits of joint action and confidence in WPPI’s planning, services and staff support. Members also expressed strong alignment with WPPI’s strategic direction, reinforcing the strength of WPPI as a member-driven organization. Member feedback reinforces how joint action delivers value in practice, reflecting confidence in WPPI’s communication, long-term planning and staff support. That engagement is not static. It evolves as member needs evolve. Through active governance, advisory groups and day-to-day collaboration, WPPI members continue to shape shared priorities that balance affordability, reliability and responsible resource stewardship. The result is a partnership built on trust, transparency and a shared commitment to serving local communities well. WHAT MEMBERS SAY WPPI’s clear and timely communication helps us stay informed and confident as we make decisions for our utility and community. WPPI’s long-term approach to power supply gives us confidence in both today’s reliability and tomorrow’s planning. The collaborative benefits of joint action and the support from WPPI staff help our utility succeed. 7 WPPI ENERGY 2025 ANNUAL REPORT Page 8 of 63 SMART ENERGY PROVIDER RECOGNITION WPPI member utilities currently holding the Smart Energy Provider designation include: 1.

That support is reflected in the number of WPPI members recognized through the American Public Power Association’s Smart Energy Provider (SEP) program. The SEP designation recognizes public power utilities nationwide for excellence in smart energy planning, energy efficiency and distributed energy programs, environmental and sustainability initiatives and customer communication. Twenty-nine WPPI member utilities hold the designation, representing roughly one-fifth of all SEP-recognized public power utilities nationwide. This level of recognition reflects the leadership of WPPI member utilities themselves. By participating in joint planning, adopting shared programs and leveraging pooled expertise, members implement advanced energy initiatives that meet rigorous national standards while remaining locally governed and community-focused. For many utilities, especially smaller systems, joint action reduces the cost and complexity of delivering the kinds of smart energy programs APPA’s SEP designation recognizes. The strong national presence of WPPI members among SEP designees demonstrates how local leadership, supported through joint action, produces results that stand out across the public power industry. 8 2025 ANNUAL REPORT WPPI ENERGY Page 9 of 63 19 22 8 9 6 4 25 1 18 16 27 7 15 28 5 26 24 29 21 14 11 3 17 13 2 20 12 2310 Page 10 of 63 26 2 2 2 33 6 9 3 5 1 1 1 2 5 49 5 1 8 1 13 1/circumflex.case 6 6 STATE REPRESENTATION OF SMART ENERGY PROVIDER DESIGNATED UTILITIES Page 11 of 63 26 2 2 2 33 6 9 3 5 1 1 1 2 5 49 5 1 8 1 13 1/circumflex.case 6 6 Nationwide Designated Utilities Numbers include SEP Utilities designations in 2023, 2024 and 2025. ^Guam is a U.S. island territory in Micronesia *Source: www.PublicPower.org/SEP Page 12 of 63 NEW RICHMOND UTILITIES YEARS FOR A CENTURY AND MORE WPPI Energy is proud to recognize member utilities celebrating significant milestone anniversaries in 2025.

The person or entity holding that REC is entitled to claim all of the environmental benefits of the associated renewable electricity generation. WPPI holds some, but not all, of the RECs associated with the electricity it receives from renewable sources. WPPI uses RECs (by retiring them within a REC tracking system) in connection with certain WPPI and member programs and to comply with state renewable energy standards. WPPI also sells some RECs, the revenues from which help lower the wholesale costs for WPPI members. The area of the chart labeled “Renewables” represents the portion of electricity received from renewable sources for which WPPI received and has not sold the associated RECs. These RECs may in the future be used by WPPI to comply with regulatory requirements, retired for other purposes or sold to third parties as described above. The portion of the chart labeled “Renewables, No RECs” represents the portion of electricity received from renewable sources for which WPPI did not purchase the associated RECs in the first instance, or for which the associated RECs have been sold. 26 2025 ANNUAL REPORT WPPI ENERGY Page 27 of 63 FUEL DIVERSITY IN A MORE COMPLEX RESOURCE ENVIRONMENT The regional generation mix continues to evolve as utilities respond to environmental objectives, reliability requirements and growing electricity demand. For WPPI, coal represented approximately 35 percent of the fuel mix in 2025, compared to 62 percent in 2010. Three baseload units in which WPPI holds ownership interests are anticipated to transition away from coal by 2035. Natural gas remains an essential dispatchable resource when intermittent renewable generation cannot meet demand. Wholesale market dynamics and regional resource planning underscore the continued importance of flexible generation in supporting reliability and resource adequacy within the Midcontinent Independent System Operator.

Among them were more than 40 representatives from approximately 25 WPPI member communities who traveled to meet directly with their U.S. Senators and House members to discuss critical policy matters aimed at keeping power costs affordable and maintaining robust grid reliability. WPPI members met directly with U.S. Sens. Ron Johnson and Tammy Baldwin of Wisconsin, Gary Peters of Michigan and Joni Ernst of Iowa. They also met with U.S. Reps. Jack Bergman of Michigan; Scott Fitzgerald, Glenn Grothman, Mark Pocan, Tom Tiffany and Tony Wied of Wisconsin; and Mariannette Miller-Meeks of Iowa, who serves on the House Energy and Commerce Committee. The group also met with staff for U.S. Sens. Chuck Grassley of Iowa and Elissa Slotkin of Michigan and for U.S. Rep. Derrick Van Orden of Wisconsin. Key discussion topics included highlighting policy proposals or ideas aimed at keeping power costs affordable while maintaining robust grid reliability and streamlining the energy generation permitting process. Attendees also discussed the importance of federal funding for both disaster response and the Low Income Heating Assistance Program. WPPI members met with U.S. Rep. Mariannette Miller-Meeks of Iowa during the American Public Power Association Legislative Rally in Washington, D.C. Miller-Meeks serves on the House Energy and Commerce Committee, which oversees key federal energy policy. WPPI staff and Michigan members met with U.S. Sen. Gary Peters during the Legislative Rally to discuss federal energy policy priorities affecting public power communities. As he prepares to retire from the Senate after serving since 2015, the WPPI membership expresses thanks to Peters for his years of public service. 42 2025 ANNUAL REPORT WPPI ENERGY Page 43 of 63 SPEAKING WITH ONE VOICE Local leadership engagement remains central to WPPI’s advocacy strategy. Through the Public Power Advocates network, member officials and utility leaders stay informed on legislative and regulatory developments and engage directly with policymakers on issues that affect their communities. When utility representatives and local elected and appointed officials share their perspectives, policymakers gain a clearer understanding of how energy policy decisions affect the customers and communities served by public power. Speaking with one voice strengthens the ability of WPPI’s 51 member utilities to preserve local authority, protect critical financing tools and support policy environments that enable long-term planning and cost competitiveness. Rally attendees also met with U.S. Rep. Scott Fitzgerald of Wisconsin during the American Public Power Association Legislative Rally in Washington, D.C. Before his election to the U.S. Congress, Fitzgerald served more than two decades in the Wisconsin State Senate, including many years as Majority Leader, where he worked with municipal utilities and other local leaders on issues affecting local utility customers. 43 WPPI ENERGY 2025 ANNUAL REPORT Page 44 of 63 CITY UTILITIES OF RICHLAND CENTER strengthening local economies Page 45 of 63 READ MORE I’m proud to represent this community in a way where everybody knows they can reach out to me directly when they start making project plans or if they just have a general question. As fire chief and utility manager for Richland Center, I speak to most residents regularly either in an official capacity or just being a citizen myself. So I’m glad that not only do local business leaders want to invest in our city and its people, but that when they have ideas, they want to talk to me about them. – Utility Manager Scott Gald WPPIENERGY.ORG/ STRENGTHENING-LOCAL- ECONOMIES 45 WPPI ENERGY 2025 ANNUAL REPORT Page 46 of 63 financial strength WPPI Energy’s strategic and consistent cost control, long-range planning and strong governance all position WPPI to continue supporting its members through industry change while maintaining competitive power costs and ensuring the capacity to invest when it matters most. Page 47 of 63 Wholesale Power Cost Performance We remain focused on operating our resources as cost- effectively as possible. Energy sales to members totaled approximately 5.1 million megawatt-hours (MWh) in 2025, an increase of 2.3 percent from the prior year. The actual average wholesale power cost was $78.72 per MWh, 5.4 percent above 2024 actual and 1.6 percent below the 2025 budget. In real terms, WPPI members paid less for wholesale power in 2025 than they did in 2012, when adjusted for inflation. This performance reflects the long-term discipline of the membership’s power supply strategy. 1 Source: U.S. Bureau of Labor Statistics, CPI-U, base year 2012. 2024 2025202320222021202020162012 2013 2014 2015 2017 2018 2019 90 80 70 60 50 $ per megawatt-hour ($/MWh) 76.7575.88 71.08 70.28 71.25 75.42 82.50 76.11 74.67 78.72 72.59 71.89 64.99 63.12 76.9176.92 78.66 77.57 76.92 75.80 76.29 75.14 63.21 63.90 64.61 57.35 54.57 56.11 Actual Adjusted for inflation 1 WHOLESALE COST OF POWER TO MEMBER UTILITIES Cost Recovery Secured by Member Contracts, Wholesale Rate WPPI’s financial strength is anchored by long-term power supply contracts with members, which extend through 2055 for 99.8% of the membership’s existing load. Together with WPPI’s wholesale rate design, which includes monthly cost adjustments, these all-requirements agreements ensure the comprehensive and timely recovery of wholesale costs. Long-term member contracts are the foundation of WPPI’s investment capacity and cost recovery. 47 WPPI ENERGY 2025 ANNUAL REPORT Page 48 of 63 Capacity for Strategic Investment While WPPI holds all-requirements member contracts through 2055 for 99.8% of our existing load, our long-term debt does not extend past 2037. These secure, long-lasting revenues and strong borrowing capacity position us well to fund future generation and transmission investments. Debt Reduction, Growing Equity To prepare for anticipated future generation and transmission investments, WPPI over the last decade has executed an intentional, sustained initiative to reduce debt and increase equity. As of December 31, 2025, total par outstanding was $220.8 million. WPPI’s equity ratio stood at 62.1%. 48 2025 ANNUAL REPORT WPPI ENERGY Page 49 of 63 With secure long-term revenue, ample debt capacity and a strong equity position, we are well-positioned to take on new generation and transmission investments that will benefit WPPI members. $ MILLIONS400 200 2024 202520232022202120202016 2017 2018 2019 342.5 411.4 388.0 324.3 305.4 290.5 273.6 252.6 237.5 220.8 100 75 50 25 2024 202520232022202120202016 2017 2018 2019 57% 64% 61% 54% 52% 49% 47% 43% 41% 43% 36% 39% 46% 48% 51% 53% 57% 59% 38% 62% OUTSTANDING PRINCIPAL DEBT TO EQUITY RATIO Debt Equity 49 WPPI ENERGY 2025 ANNUAL REPORT Page 50 of 63 financial summary Page 51 of 63 OPERATING REVENUES LONG-TERM BOND RATINGS 2025 $ MILLIONS 500 600 200 100 300 400 2024 2025202320222021 472.4 509.2 443.5 436.9 473.3 A1A+ A 51 WPPI ENERGY 2025 ANNUAL REPORT Page 52 of 63 58.3% Purchased power 18.2% Transmission 8.5% Fuel expense 4.3% Operation and maintenance 5.7% Customer service and administrative and general 3.9% Depreciation and amortization 1.1% Taxes 2025 OPERATING EXPENSES 52 2025 ANNUAL REPORT WPPI ENERGY Page 53 of 63 See our complete financial statements online at www.wppienergy.org SUMMARY STATEMENTS OF NET POSITION December 31, 2025 2024 ASSETS Current assets $ 145.3 $ 151.3 Non-current assets 304.9 281.6 Capital assets, net 314.0 326.3 Total assets 764.2 759.2 Deferred Outflows of Resources 9.4 12.0 LIABILITIES Current liabilities 55.8 51.8 Non-current liabilities 10.6 10.9 Long-term debt, net 217.2 236.7 Total liabilities 283.6 299.4 Deferred Inflows of Resources 101.6 99.1 NET POSITION $ 388.4 $ 372.6 SUMMARY STATEMENTS OF REVENUES, EXPENSES AND CHANGES IN NET POSITION Year ended December 31, 2025 2024 Operating revenues $ 473.3 $ 436.9 Operating expenses 473.8 435.0 Operating income (loss) (0.5) 1.8 Non-operating revenues (expenses), net 19.5 19.2 Future recoverable costs (3.3) (4.0) Change in net position 15.8 17.1 Net position, beginning of year 372.6 355.5 NET POSITION, END OF YEAR $ 388.4 $ 372.6 (in $ Millions) (in $ Millions) 53 WPPI ENERGY 2025 ANNUAL REPORT Page 54 of 63 Page 55 of 63 Page 56 of 63 1425 Corporate Center Drive Sun Prairie, WI 53590-9109 Ph: (608) 834-4500 wppienergy.org ©2026 Printed on recycled paper Page 57 of 63 2024 POWER SUPPLY RESOURCES Owned Generation Fuel Capacity (MW) South Fond du Lac Units 1 & 4 Gas 154 Boswell Unit 4 Coal 117 Elm Road Generating Station Coal 106 Island Street Peaking Plant Gas 52 Worthington Wind Turbines Wind 2 Power Purchase Agreements Fuel Capacity (MW) Bishop Hill III Wind Energy Center Wind 132 WPS System Energy 50 Point Beach Nuclear Nuclear 117 Point Beach Solar Solar 99 Nelson Energy Center Gas 90 Butler Ridge Wind 54 Top of Iowa II Wind 50 Member-Owned Generation Gas, Oil 45.2 Barton I Wind 30 Forward Wind Energy Center Wind 27.5 Kimberly Hydro Hydroelectric 2.1 Richland Center Renewable Energy Biogas 1.8 Jefferson Solar Solar 1 Community Solar Gardens Solar 0.6 2025 FUEL MIX 35.0% Coal 20.9%Nuclear 10.3% Renewables 19.1% Natural Gas 14.7% Renewables: No RECs1 2025 POWER SUPPLY RESOURCES AVERAGE POWER COST TO MEMBERS AT A GLANCE Member-owned, not-for-profit WPPI Energy serves 51 locally owned electric utilities. 1425 Corporate Center Drive | Sun Prairie, WI 53590 | 608-834-4500 | wppienergy.org The Joint Action Advantage Together, WPPI members have built a reliable, competitive and responsible power supply.

The person or entity holding that REC is entitled to claim all of the environmental benefits of the associated renewable electricity generation. WPPI holds some, but not all, of the RECs associated with the electricity it receives from renewable sources. WPPI uses RECs (by retiring them within a REC tracking system) in connection with certain WPPI and member programs and to comply with state renewable energy standards. WPPI also sells some RECs, the revenues from which help lower the wholesale costs for WPPI members. The area of the chart labeled “Renewables” represents the portion of electricity received from renewable sources for which WPPI received and has not sold the associated RECs. These RECs may in the future be used by WPPI to comply with regulatory requirements, retired for other purposes or sold to third parties as described above. The portion of the chart labeled “Renewables, No RECs” represents the portion of electricity received from renewable sources for which WPPI did not purchase the associated RECs in the first instance, or for which the associated RECs have been sold.

Long-Term Utility Success Your WPPI wholesale power agreement is key to how your utility delivers reliable electric service, competitive costs and local control. A Legacy of Long-Term Planning Over decades, members have made long-term commitments, extending their contracts as needs evolved. Their decisions built the diverse resources that power your community today. WPPI MEMBERS Page 60 of 63 June 25, 2026 2 Long-Term Decisions. Strong Results. WPPI is the low-cost leader for powering local communities. Member utilities provide highly competitive electric rates. Meeting Future Needs Future needs are already visible. Some are reflected in the lighter portions of this capacity needs chart. The same long-term planning approach that positioned your utility for success in the past continues to identify and plan for the needs ahead. Extending the agreement helps preserve continued access to cost-effective long-term wholesale power for your community. Page 61 of 63 June 25, 2026 3 Why Extend Now ? WPPI is actively pursuing opportunities to continue serving your community’s needs. These and other beneficial solutions are not possible without a member agreement end date that is sufficient to back the needed financing and contracts. Transmission Investment WPPI's ownership interest in American Transmission Co. (ATC) provides returns that help lower wholesale power costs for your community. As the regional grid build- out unfolds, future ATC investments will require financing beyond what WPPI’s margin alone can support. The extension will help preserve WPPI's ability to finance future ATC investments and continue receiving returns that help offset your community’s wholesale power costs.

A Record of Success • WPPI is the low-cost leader for powering local communities. • Overall WPPI member rates are very competitive compared to utilities in the region. • Together WPPI members have achieved a diverse, low-cost power supply. Your Community and WPPI • Your WPPI wholesale power agreement is key to how your utility provides electric service at competitive costs. • The need for additional, cost-effective resources to power WPPI member communities is visible now. • WPPI is actively pursuing electric generating resource options, transmission system investments and financial transactions for this purpose. Why Extend Now? • The current 2055 end date of the WPPI member agreement falls short of the typical 30 years needed for securing the most cost-effective long-term solutions to meet your community’s energy needs. • The request is for an 18-year extension of the current 2055 end date. • An 18-year extension is not new for WPPI members. Your previous extension was also 18 years. What if WPPI and Members Do Not Extend? The existing agreement continues through 2055. Members would have no rights to WPPI’s power supply or services beyond that term.
