Overview
Old National Bank is an American regional banking brand with roots dating to 1834. It is operated by Old National Bancorp, a bank holding company headquartered in Chicago, Illinois, and Evansville, Indiana. The organization has grown through a combination of organic expansion, branch purchases, bank acquisitions, and mergers, becoming one of the largest banking companies headquartered in Indiana and a significant regional financial institution in the United States. The bank’s service footprint extends across Illinois, Indiana, Iowa, Kentucky, Michigan, Minnesota, North Dakota, Tennessee, and Wisconsin. Its network has included nearly 200 retail branches and approximately 250 banking centers, although the exact count changes as acquisitions are integrated and branch networks are rationalized. The institution’s regional model combines community-oriented retail banking with commercial banking, wealth management, trust, investment, and retirement services. For individual customers, Old National offers transaction and deposit accounts, savings products, certificates of deposit, consumer lending, residential mortgages, and related digital and branch-based banking services. Small businesses receive deposit accounts, lending, cash-management, and other financial support. Commercial and institutional clients can use checking and savings products, commercial loans and credit lines, corporate cards, treasury management, merchant services, capital-markets capabilities, and other specialized banking services. Wealth-management activities include investment, fiduciary, trust, and retirement-related products and advice. Old National’s growth accelerated in the 1990s and 2000s through a series of acquisitions. It purchased First United Savings Bank in 1995 and Workingmens Capital Holdings in 1996. In 2009, former Charter One branches in Indiana were converted to the Old National brand after Old National acquired Charter One’s Indiana operations. The bank subsequently expanded through transactions involving Monroe Bancorp, failed-bank deposits from Integra Bank, Bank of America branches in Indiana and Michigan, and several community banks in Indiana and Michigan. The institution broadened its Wisconsin and Minnesota presence through the acquisitions of AnchorBank in 2016, Anchor Bank of Minnesota in 2017, and KleinBank branches in 2018. Its most consequential recent combination was the 2021 merger with First Midwest Bancorp. The combined organization retained the Old National name and maintained a dual headquarters structure in Chicago and Evansville. In 2024, CapStar Financial Holdings combined its operations with Old National, making CapStar Bank a division of Old National Bank. Old National also announced an agreement in 2024 to acquire Minnesota-based Bremer Bank; the reference material states that the transaction was completed in October 2025 and produced a combined institution valued at approximately $70 billion. The brand operates in a competitive regional-banking environment shaped by deposit gathering, commercial-credit demand, interest-rate changes, digital banking adoption, regulatory requirements, and consolidation among community and middle-market banks. Its positioning emphasizes a broad regional platform while preserving local-market banking relationships. The Louisville branch shooting in April 2023, in which five employees were killed and other people were injured, became a major event associated with the brand and generated extensive public attention. Despite this tragedy, Old National remains an active regional bank with a diversified portfolio of consumer, commercial, and wealth-management services.
History
Old National Bank traces its origins to 1834 and developed from an Evansville-centered institution into a multistate regional banking organization. Its expansion has generally followed the pattern of American community and regional banking: strengthening its home-market franchise, entering adjacent states, purchasing branches or smaller banks, and broadening its product set beyond traditional deposits and loans. The bank’s acquisition program became particularly visible in the 1990s. In November 1995, Old National acquired Greencastle-based First United Savings Bank in an all-stock transaction reported at $18 million. In 1996, it acquired Bloomington-based Workingmens Capital Holdings, including Workingmens Federal Savings Bank, in a stock transaction whose value was not disclosed in the reference material. These deals expanded the organization’s Indiana presence and reinforced its position as a consolidator of local banking institutions. Old National continued expanding during the financial-sector restructuring that followed the global financial crisis. In 2009, branches of Charter One’s Indiana bank operations adopted the Old National name after Old National acquired those operations. In January 2011, the company acquired Bloomington-based Monroe Bancorp and its Monroe Bank subsidiary for $90 million in stock. Later in 2011, following the closure of Integra Bank by the Federal Deposit Insurance Corporation, Old National received the transfer of Integra’s deposit accounts, except for certain brokered deposits. In 2012, Old National purchased 24 Bank of America retail branches in Indiana and Michigan. The organization then completed several community-bank acquisitions in 2014, including Tower Bank in Fort Wayne, Indiana; United Bank in Ann Arbor, Michigan; Lafayette Savings Bank in Lafayette, Indiana; and Founders Bank & Trust in Grand Rapids, Michigan. These transactions expanded both its geographic coverage and its access to commercial and consumer customers in Indiana and Michigan. The next phase of growth reached Wisconsin and Minnesota. In May 2016, Old National acquired AnchorBank, described in the reference material as Wisconsin’s third-largest bank based in the state, in a transaction valued at approximately $461 million. In August 2017, Old National agreed to acquire Minnesota-based Anchor Bank. That transaction was expected to add 17 locations in the Twin Cities and one in Mankato, together with approximately $1.7 billion in deposits and $2.1 billion in assets. In 2018, KleinBank announced that its 21 locations in Minnesota’s western Minneapolis suburbs would be acquired by Old National, further expanding the company’s Twin Cities-area presence. A defining corporate event occurred in 2021, when Old National merged with First Midwest Bancorp. The combined company retained the Old National name and maintained headquarters in both Chicago and Evansville. The merger increased the scale of the organization and strengthened its position in commercial banking and middle-market finance while preserving a broad community-banking footprint. In 2023, an employee of the bank carried out a mass shooting at the Louisville branch, killing five employees and injuring eight other people, including a police officer. The event was one of the most serious tragedies in the bank’s history and prompted public mourning and national attention. Old National continued its consolidation strategy in the following years. In 2024, CapStar Financial Holdings combined its operations with those of Old National, with CapStar Bank becoming a division of Old National Bank. Also in 2024, Old National announced the planned purchase of Minnesota-based Bremer Bank for approximately $1.4 billion. The supplied reference material reports that the transaction was finalized in October 2025 and resulted in a combined bank valued at roughly $70 billion. Today, Old National operates as a diversified regional banking platform. Its activities span retail deposits, consumer and residential lending, small-business finance, commercial credit, treasury and payment services, capital markets, wealth management, investment, trust, and retirement services. Its history reflects the continuing consolidation of Midwestern banking, with the Old National brand serving as the customer-facing identity across an increasingly broad network.
