MGIC: MGIC Investment : 2025 Corporate Sustainability Report

2025 Corporate Sustainability Report Introduction Governance and Leadership Our People Empowering Communities Environmental Management Appendix Letter From Our CEO 3 2025 CORPORATE SUSTAINABILITY REPORT At MGIC, we believe that sustainable, accessible homeownership is a cornerstone of financial security and strong communities. For decades, our product - private mortgage insurance (PMI) - has helped families purchase homes sooner than they otherwise could, allowing them to invest in their futures and build generational wealth. This mission is as important today as ever - especially as the path to homeownership remains challenging for many. Our role in the housing ecosystem carries a responsibility not just to homebuyers but also to the stakeholders who make our work possible - our co-workers, customers, shareholders, community partners and industry organizations. We succeed together, and that success is built on transparency, collaboration and a commitment to long-term impact. In the following pages, you will see how we bring this mindset to life. Over the past year, we have strengthened our leadership communication and transparency efforts internally, launched a new learning model to enhance professional growth for our co-workers, and deepened our investment in communities through monetary and in-kind donations. We also opened our corporate office doors to key nonprofit partners like Habitat for Humanity and Acts Housing, reinforcing our shared commitment to homeownership access for all. The need for solutions like ours is clear. On average, a household earning the national median income of $74,580 would need 27 years to save 20% plus closing costs for a median-priced home. MGIC makes homeownership achievable sooner - helping families make memories today rather than plans for tomorrow. None of this happens in isolation. Our engaged Board of Directors and corporate leadership help drive our vision, ensuring that MGIC's long-term sustainability is embedded in everything we do. Through their vision - and the collective efforts of our co-workers and partners - we remain focused on maximizing both the value we create for stakeholders and the impact we have on the communities we serve. Thank you for your continued partnership in this mission. Together, we are not just driving the path to homeownership - we are strengthening futures.

MGIC Investment Corporation (NYSE: MTG) is the parent company of Mortgage Guaranty Insurance Corporation (MGIC). We are a Wisconsin corporation, with long, proud roots in our community. We were founded in 1957 by Max Karl, a Milwaukee real estate attorney who invented the modern form of private mortgage insurance (PMI) to make the homebuying process less expensive for borrowers and less cumbersome than government-sponsored mortgage insurance for lenders. What is PMI Private mortgage insurance provides a critical component of the residential mortgage finance system by protecting mortgage lenders from credit losses. Through our PMI, we provide our customers, which include banks, mortgage bankers, mortgage brokers, credit unions, mortgage loan servicers, mortgage investors, and government-sponsored entities, with credit loss protection. MGIC insures a portion of the mortgage loan in the event of a default. This protection reduces (and, in some instances, eliminates) the losses our customers would experience if a homeowner were to default on a mortgage loan. 2025 CORPORATE SUSTAINABILITY REPORT How PMI Works Our core business has been designed to reduce barriers to homeownership by making it possible for a borrower to buy a home sooner, which is especially impactful for first-time homebuyers. Buying a home usually involves a challenging hurdle for many families: coming up with a sufficient down payment. MGIC's PMI allows borrowers to make a smaller down payment and shorten the time to homeownership. For the average borrower, it can take years to save for the typical 20% down payment. With MGIC's PMI, families can purchase homes with as little as 3% cash down, thus accelerating their access to homeownership. PMI Fast Facts Making Homeownership Possible Sooner Down payments as low as 3% Without PMI, it could take 27 years for a middle-class family to save up for a 20% down payment More than 800,000 borrowers used PMI to purchase a home or refinance a loan in 2023 64% of purchase loans with PMI went to first-time homebuyers Nearly 35% of borrowers had annual incomes below $75,000 U.S. Mortgage Insurers, MI in Your State Report, 2024. Overcoming the Homebuying Hurdle PMI allows a borrower to make a smaller down payment than lenders typically require.
