Marathon Bancorp, Inc. is a Maryland corporation formed in December 2020 to serve as the mid‑tier holding company for Marathon Bank following the bank’s mutual holding company reorganization and public offering. The company does not conduct independent banking operations; its primary purpose is to own and support Marathon Bank as a wholly owned subsidiary. Marathon Bancorp is authorized to pursue additional activities permitted for bank holding companies, such as acquiring other banking or financial services firms, and it is subject to regulation and examination by the Federal Reserve Board and the Wisconsin Department of Financial Institutions.

Marathon Bancorp generates revenue from the earnings on the net proceeds it retained from its initial public offering and from dividends received from Marathon Bank. The company does not own or lease property or maintain a separate workforce; it relies on the premises, equipment and officers of Marathon Bank for its administrative functions. Consequently, its cash flow depends entirely on the investment income from its held proceeds and the dividend distributions from its subsidiary bank.

Marathon Bancorp’s position in the financial services industry derives from its ownership of Marathon Bank, a Wisconsin‑chartered savings bank that operates in the Marquette, Ozaukee, Milwaukee and Waukesha county regions. Marathon Bank competes with other community banks, regional banks, credit unions and larger financial institutions that offer similar deposit and lending products. Its competitive advantages include a community‑oriented business model, personalized service and a strategic focus on growing commercial and multifamily real estate loans to improve asset yields. The bank’s strong capital ratios and its status as “well capitalized” under regulatory standards further support the holding company’s standing within the sector.

Marathon Bancorp’s customers are its shareholders, which consist of Marathon MHC holding approximately 55 percent of the outstanding shares and public investors owning the remaining 45 percent. The company does not serve retail or commercial clients directly; its economic relationship with end‑users is mediated through Marathon Bank’s deposit and loan relationships with individuals, businesses and organizations in its market areas.
