Company Overview

Old Second Bancorp, Inc. is a bank holding company headquartered in Aurora, Illinois, operating primarily through its wholly owned banking subsidiary, Old Second National Bank. The company operates in the U.S. regional banking industry and provides commercial banking, retail banking, treasury management, wealth management, and lending services. Its primary revenue drivers are net interest income generated from commercial and consumer lending activities, along with fee-based income from deposit services, trust operations, and wealth management offerings. The bank primarily serves small- to mid-sized businesses, commercial real estate clients, municipalities, and individual consumers across the Chicago metropolitan area and surrounding Midwestern markets.

The company traces its origins to 1871 with the founding of Old Second National Bank. Over time, it evolved from a community-focused bank into a broader regional banking institution through branch expansion and acquisitions. A major step in its growth strategy occurred with the acquisition of West Suburban Bancorp, Inc. in 2016, which significantly expanded its market presence in the greater Chicago area. Old Second Bancorp has positioned itself as a relationship-focused commercial bank with strong local market penetration, emphasizing conservative credit practices, community banking relationships, and middle-market commercial lending expertise.

Business Operations

Old Second Bancorp generates revenue primarily through its banking operations conducted by Old Second National Bank. Its principal operating activities include commercial and industrial lending, commercial real estate lending, residential mortgage lending, consumer lending, deposit gathering, and fee-based financial services. The company reports banking activities as its primary operating segment, with business lines spanning commercial banking, retail banking, treasury management, and fiduciary and wealth management services. Net interest income remains the dominant contributor to earnings, supported by loan portfolio growth and deposit franchise expansion.

The company’s operations are concentrated in Illinois, particularly within the Chicago metropolitan statistical area and suburban markets. Old Second controls a network of retail branches, commercial banking offices, digital banking platforms, and treasury management infrastructure. It also maintains trust and wealth management capabilities serving both retail and institutional customers. Strategic acquisitions and branch optimization efforts have supported operational scale, while partnerships with payment networks and technology vendors support digital banking, online treasury services, and customer transaction processing.

Strategic Position & Investments

Old Second Bancorp’s strategic direction has centered on disciplined commercial banking growth, balance sheet expansion, and selective acquisitions within attractive Midwestern banking markets. Management has emphasized commercial and industrial lending growth, commercial real estate lending discipline, and expansion of low-cost core deposits. The company has also invested in digital banking capabilities and treasury management services to strengthen client retention and compete more effectively with larger regional banking institutions.

The acquisition of West Suburban Bancorp, Inc. represented one of the company’s most significant strategic investments, materially increasing market share and branch density in suburban Chicago markets. Old Second has also pursued organic expansion through relationship banking teams and specialized lending capabilities. Public filings and investor communications indicate continued focus on capital management, asset quality, and operational efficiency rather than aggressive geographic diversification. Data regarding involvement in emerging technology sectors beyond standard banking digitization initiatives remains inconclusive based on available public sources.

Geographic Footprint

Old Second Bancorp operates primarily within the United States, with its core footprint concentrated in Illinois. The company’s headquarters are located in Aurora, Illinois, and its branch network serves communities throughout the greater Chicago metropolitan area, including suburban and regional commercial corridors. Its lending and deposit operations are focused largely on local and regional customers rather than international banking markets.

The company’s market presence is strongest across northeastern Illinois, where it maintains commercial banking relationships with middle-market businesses, municipalities, and retail customers. While Old Second does not maintain a significant international operational footprint, it participates in standard banking activities that may support customer transactions with national and international components. Public disclosures do not indicate material direct foreign operations or substantial international investment exposure.
