RESPONSIBLY POWERING A BRIGHTER TOMORROW As an electric cooperative, Associated’s employees and

$1B+ invested in reducing air emissions since 2005

rural members live where we generate electricity and take pride in caring for the air we breathe, water we drink and land we farm. Accountability to each other, and the resources we all depend on, is the foundation of Associated’s strong culture of compliance, safety, innovation and environmental stewardship.

Balanced generation fleet shrinks carbon footprint

36.4% decrease in carbon emissions since 2005

In the push and pull between the competing priorities of reliable, affordable and responsible power, Associated remains committed to managing a balanced generation fleet that decreases environmental impact while meeting members’ power supply needs.

Associated’s diverse generation fleet of coal, natural gas, liquid fuel, wind and hydropower resources allows for optionality that enables the co-op to take advantage of weather and lower carbon dioxide (CO₂) emissions.

Overall, our CO₂ emissions per megawatt-hour produced has been reduced by more than a third since 2005, thanks to alternative generation resources, plant heat rate improvements and a shift to natural gas generation.

$115M invested to meet Coal Combustion Residuals and Effluent Limitations Guidelines issued by the EPA since 2015

Looking to the future, Associated’s long-range environmental planning is key to continued environmental stewardship as demand for energy increases. When forming our long-term investment and development plans, a range of carbonreduction scenarios are evaluated and prioritized for compliance with all federal and state regulations. Currently, Associated is constructing two new natural gas peaking units, one in Missouri and one in Oklahoma, to reliably power member needs. The new simple-cycle units will comply with all emissions requirements, be capable of burning a blend of up to 30% hydrogen if viable and economical, and have selective catalytic reducers installed to reduce nitrogen oxide emissions.

Associated’s alternative generation legacy continues At Associated’s formation in 1961, hydropower from manmade reservoirs was a key source of affordable, responsible power for member-owners.

Today, hydropower generated by federal dams in Missouri, Oklahoma, Arkansas and Texas remains a vital alternative generation resource in Associated’s portfolio. Hydropower’s role as a low-cost, carbonfree resource generated 5% of member energy needs in 2024, with Associated contracting purchases of available hydropower from the U.S. Department of Energy’s Southwestern Power Administration.

Another important alternative resource – wind energy – has been part of the Associated generation mix since the 2000s. Associated solidified its role as a national wind energy leader by helping to bring the first utility-scale wind farm to Missouri in 2007, thanks to long-term purchase agreements and the cooperative’s strong high-voltage transmission system. Associated buys the output from eight wind farms located in Missouri, Kansas and Oklahoma, totaling 1,240 MW of contracted wind energy. In 2024, wind energy generated 17% of member energy needs.

Technology reduces air emissions As technology continues to advance, Associated remains vigilant to invest in proven technologies that allow the cooperative to reduce its environmental impact. Associated’s air quality improvements cost more than $45 million annually, including fixed and operating costs, to achieve significant results.

Associated was one of the first utilities in the country to construct selective catalytic reduction equipment on large cyclone units, reducing nitrogen oxide emissions by about 86% since 1994. The cooperative is proud of its efforts to install low nitrogen oxide burners, use “over- fire air” technologies at its coal units and convert to low-sulfur coal. Collectively, these actions have reduced mercury emissions by 93% since 2008 and lowered sulfur dioxide emissions by nearly 95% over the last 30 years.

Protecting water quality Water is a vital resource for power plant operations and Associated is committed to ensuring the quality of the water we use. At all of our plants, Associated fully complies with the Clean Water Act, which requires water and discharge permits, and Effluent Limitation Guidelines, which regulates the use of water in industrial and commercial facilities.

Primarily a cooling source, water used for generating electricity for our members comes from the Mississippi River; groundwater wells; purchased water supplies; and Thomas Hill Reservoir, which we built for our power plant.

Bottom left: Ryan Dawson, chemical lab technician, tests water quality at Thomas Hill Energy Center, a key component of Associated’s environmental commitment and maintenance efforts.

06

One of Associated’s largest generating units can use about 330,000 gallons of water per minute on a hot day, with the bulk of water used to cool and condense steam used to generate electricity. Associated removes corrosive minerals that could damage equipment from the water we consume, then returns 99% of all water to the source after its use in as good or better condition than when it was withdrawn from the river or lake.

Additionally, Associated’s efforts to safely manage coal ash at the New Madrid and Thomas Hill power plants led to all ash ponds, which were previously used to manage byproducts from power generation, to be either closed or in the process of closing. To further decrease environmental impact, these plants converted to dry handling and disposal of coal ash in accordance with federal and state regulations, reducing water supply needs and protecting groundwater.

Award-winning conservation of habitat and wildlife Associated is a national leader in mine reclamation, transforming hundreds of acres of old mining pits into pasture, woods and water benefiting fish and wildlife. Reclamation efforts have been twice recognized by the U.S. Department of the Interior for innovative and successful mine reclamation and restoration of the Bee Veer Mine near Macon, Missouri. Nearby, Associated annually leases its 4,950-acre Thomas Hill Reservoir and surrounding 4,381 acres to the Missouri Department of Conservation (MDC), partnering with the agency to manage the area for fish, wildlife and recreation.

Another successful partnership with MDC takes flight each spring: a peregrine falcon restoration program. Once on the endangered species list, peregrine falcons are again thriving in Missouri, thanks in part to efforts by Associated.

Additionally, Associated manages its cooperative-owned acreage with an eye on conservation. Pollinator plots at Thomas Hill Energy Center and Nodaway Power Plant, seeded with locally sourced native seed mix, enhance biodiversity and support pollinator populations in northern Missouri. And true to our rural roots, Associated leases land to more than 40 farmers for crop production, haying and pasture ground, furthering our responsible use of natural resources on behalf of members.

POWER WITH PURPOSE At Associated, our members empower the cooperative to be a force for good across the rural Midwest.

1.12 OSHA recordable incident rate in 2024, tied for all-time record

Whether it’s generating safe and affordable electricity, giving back to area non-profits, activating volunteer efforts or driving economic growth, Associated is committed to caring for its members and employees while improving the lives of our home communities.

Together, we’re generating power with purpose.

Focused on reliable, affordable electricity The need for low-cost power supply rural member-consumers could depend on was the driving force behind Associated’s creation as an electric cooperative in 1961. Today, our members continue to

$281M in member rate discounts from 2019-2024

authorize Associated to prioritize reliable, affordable energy.

In 2024, the bi-annual member satisfaction survey results for Associated’s member systems showed reliability was the most important attribute of electricity (56%), followed by affordability (40%) and zero carbon and/ or renewable resources (4%). In grading their local distribution cooperative, members ranked an overall score of 83 on the 100-point scale of the American Customer Satisfaction Index (ACSI®), nine points higher than the national average for investor-owned utilities and eight points higher than municipal utilities.

Associated never forgets the rural members we serve, who are largely working families of modest means. 49% of Associated’s memberconsumers are older than age 55, with 22% having a household income

just an expectation – it’s a necessity. Associated’s diverse generation fleet helps the cooperative select the lowest-cost generation resource to keep costs competitive. In 2024, Associated’s average member rate was $56/

Additionally, everyday member-consumers can receive assistance to control energy costs through the Take Control & Save program, a suite of energy efficiency services and rebates. Since 2008, Associated and member systems have invested more than $74 million to offer high-efficiency heat pump water heater rebates, commercial energy audits and a business lighting rebate program.

Investing in rural economies benefits member communities Affordable, reliable power supply is a catalyst for attracting regionwide economic growth. Doing all we can to showcase our home region – and benefits of doing business here – is a key role Associated plays for member systems.

Associated’s Power4Progress program provides resources to develop, lead or participate in activities that increase electric load and provide economic/community growth or sustainability within the service territory. Support includes key accounts, residential development loan programs, commercial development, USDA rural economic development loan assistance and more. Since 2023, the program’s initiatives have facilitated nearly $1 million in investments within our service territory.

Safety is the top priority Generating electricity safely is an obligation Associated has to its members and local communities. In everything we do, safety is our foremost focus. In 2024, Associated’s safety culture shined as employees tied the cooperative’s all-time safety record, posting an OSHA Recordable Incident Rate (RIR) of 1.12, below the industry standard of 1.5.

Associated prioritizes reducing all employee injuries, with a special focus on soft tissue injuries, through a program called Safety in Motion and warn of complacency, rushing and fatigue with a Safe Start program.

All employees complete multiple safety training sessions annually, and weekly meetings with employees identify hazards and communicate requirements, helping reduce the potential for injuries. Extra attention is also paid to tracking near-miss events, identifying and measuring the potential for serious injury or fatalities, for improvement.

When accidents occur, emergency response teams (ERT) at New Madrid Power Plant and Thomas Hill Energy Center are the unsung heroes of Associated. Twenty-five of these employees at both locations put their lives on the line to safeguard the people, plant operations and communities they call home. Members serve for three years and are forged through highly technical and extensive training, with several also serving as volunteer firefighters and sharing knowledge with local fire departments.

Associated further serves as a safety resource for member systems, helping member cooperatives comply with state and federal environmental, health and safety regulations like spill prevention, control and countermeasure plans, PCBs (polychlorinated biphenyl management), stormwater pollution prevention plans and land disturbance permits, air emissions from mobile/small sources and Tier II chemical reporting.

Workforce development, amplifying employee value Associated’s more than 700 employees are the cooperative’s greatest asset.

We leverage the talents and contributions of every individual, encouraging personal responsibility, teamwork and quick action for the benefit of members.

Associated’s success begins with effective leadership programs that encourage the development of a diverse, inclusive workforce through training designed to build awareness of perceptions, biases and value of diversity. Leadership bench strength is enhanced by a talent review and succession planning process.

To help employees reach their fullest potential, Associated invests in training opportunities, individualized employee career planning and resources to help employees at work and in their personal lives. Listening to employee concerns and areas for improvement is also a priority. To monitor employee engagement, Associated launched a continuous listening survey program, which yielded a 74% participation rate in 2024 and ranked Associated in the top 10% of the Energy and Utilities category.

Best-in-class benefits are another vital element of Associated’s employee experience, attracting and retaining top talent. The cooperative’s holistic well-being initiative, EmPower, offers programs, resources and incentives to employees based on four dimensions of well-being: health, wellness, wealth and harmony. Other benefits include paid time off, medical leave, education assistance, parental leave, life insurance and health savings accounts.

To further support employees, Associated created employee resource groups based on shared characteristics or life experiences. WATT (Women Amplifying Their Talents) supports women looking to amplify their talents and build their careers. VOLT (Vets Organized to Learn Together) enhances the employee experience for veteran employee and job seekers.

Associated’s employee assistance program (EAP) provides confidential resources, including support and counseling services to help employees and families resolve issues affecting the quality of life at home or work.

Giving back to local communities Wherever they live and work, Associated and its employees give back to the communities we call home. Employee-led contributions committees review grant requests monthly and enable Associated to give back thousands of dollars to local charities. In 2024, Associated contributed more than $100,000 to over 50 nonprofit organizations for worthwhile efforts across our service territory.

Associated is also proud to be among the largest partners of United Way of

the Ozarks, directly helping to improve the lives of thousands of children, adults and families through the services of their diverse member agencies.

Associated was named the United Way of the Ozarks’ Corporate Humanitarian of the Year after employees raised nearly $90,000 for the charity in 2024.

Cooperatives recognize the power of volunteerism and the gift of time, too. Associated’s nonunion employees are awarded time off annually to volunteer for community nonprofits. Together, employees generously give time to grassroots efforts that benefit food banks, children’s hospitals, foster homes and other nonprofits helping those in need.

LED BY OUR MEMBERS-FIRST MISSION Associated works diligently to serve our cooperative system, but with a distinct advantage: Our memberowners lead the company. Associated’s grassroots,

6 G&T cooperative member-owners

bottom-up governance ensures member-consumers are represented in all decisions, one of the many benefits of being an electric cooperative member. Power supply – by members for members – is Associated’s greatest strength, ensuring reliable, affordable and responsible electricity is always prioritized.

Three-tiered structure serves member energy needs

51 local distribution cooperatives served

The Associated system is a unique three-tiered system of electric cooperatives, united by the common purpose of serving member-consumers with reliable, affordable and responsible electricity.

The first tier is comprised of 51 local distribution cooperatives in Missouri, southern Iowa and northeast Oklahoma. These distribution cooperatives provide electric service directly to more than 935,000 member meters, including businesses, farms and households representing 2.1 million people.

At the second tier are the six regional G&T cooperative-owners responsible for transmitting power generated by Associated to the 51 distribution cooperatives.

The G&Ts serve six geographical areas across the service area and oversee

the operation, construction and maintenance of the high-voltage transmission system built by member investment.

In 1961, the G&Ts formed the system’s third tier with the creation of Associated, which was subsequently given responsibilities for generation and power procurement, leaving transmission as the primary responsibility of Associated’s six owner G&Ts. Together, this collaborative system of G&Ts and distribution cooperatives brings efficiency through specialization to meet daily power needs. The entire threetiered system benefits from economies of scale and, since each tier can react quickly to changes, the overall competitiveness of the system is improved.

Member-led leadership guides Associated Cooperatives are democratic organizations controlled by their members, who actively participate in setting policies and making decisions. Representatives (directors/trustees) are elected among the membership and are accountable to them. In distribution cooperatives, members have equal voting rights (one member, one vote); G&T cooperatives are organized in a democratic manner.

Associated’s six G&T cooperative-owners each send two directors to serve on the Associated board of directors, typically the G&T manager and a director from the G&T’s board. Associated’s board meets monthly with the executive team to review, discuss and approve issues. The board determines the strategic direction for Associated, tests the cooperative’s business strategy, approves key investment decisions and sets the wholesale power supply rate to ensure Associated meets its financial responsibilities and stays focused on its member-driven mission.

Our 12-member board is sized to act quickly to seize opportunities, assess risks and represent member-consumer interests. Board and management have proven their ability to quickly initiate and implement action to mitigate challenges. Enterprise risk management, including the key elements of environmental, social and governance priorities, are overseen by senior management and independent board committees.

Safeguarding cybersecurity, systems and facilities Associated’s cybersecurity and physical security department leads a comprehensive effort to monitor physical and cyber threat activity 24/7, 365, with the ability to respond rapidly to threats.

Associated deploys industry best practices to assess risks and mitigate threats, including sophisticated endpoint detection and response tools on servers and workstations; strong physical and digital access control program audited on a routine basis; a quantitative and qualitative risk-based approach for measuring cyber risk; adherence to all federal Critical Infrastructure Protection (CIP) compliance regulations for both physical and cybersecurity; and regular maintenance of a comprehensive business continuity plan.

To better monitor and protect member cooperatives throughout the threetiered system, Associated established a cybersecurity umbrella program called Cyber Dome. A first-of-its-kind solution, Cyber Dome scaled Associated’s internal cybersecurity tools and operations center to also safeguard our

member-owners, reducing cyber risk and offering sophisticated protection, detection and response capabilities to cooperatives at a fraction of the cost.

The end goal: ensure safe, reliable, affordable power for member systems.

Culture of compliance Associated participates in and is regulated by the North American Electric Reliability Corp. (NERC), a not-for-profit international regulatory authority whose mission is to assure the effective and efficient reduction of risks to the reliability and security of the electric grid.

NERC develops and enforces reliability standards; annually assesses seasonal and long-term reliability; monitors the bulk power system through system awareness; and educates, trains and certifies industry personnel.

NERC’s area of responsibility spans the continental United States, Canada and the northern portion of Baja California, Mexico. NERC is the Electric Reliability Organization (ERO) for North America, subject to oversight by the Federal Energy Regulatory Commission (FERC) and governmental authorities in Canada. NERC’s jurisdiction includes users, owners and operators of the bulk power system, which serves nearly 400 million people.

Commitment to transparent, ethical reporting As part of its compliance activities, Associated has a well-earned reputation of responsiveness to regulatory authorities, industry groups, member-owners and the general public. Most importantly, Associated prioritizes transparent, ethical reporting and information-sharing.

Areas of special attention include NERC and OSHA filings, financial

10,288 miles of member-owned transmission, one of America’s largest integrated transmission systems

rating agency meetings with Standard & Poor’s, Moody’s and Fitch, and comprehensive operational and annual reports with financial statements.

Additionally, Associated regularly informs member systems with board meeting recaps, newsletters, financial/operational summaries and industry news.

Associated’s Annual Meeting of Members, held in Branson, Missouri, each summer, provides an in-person touchpoint to educate members, report on cooperative performance and conduct business on behalf of memberconsumers. Associated also visits member system cooperatives’ annual
