Old Second Bancorp, Inc. (OSBC) - Canvas Business Model: Value Propositions

You're looking at the core offerings Old Second Bancorp, Inc. (OSBC) puts on the table for its customers and the market as of late 2025. It's a blend of traditional local service backed by specialized, high-yield capabilities.

Full-service community banking with a regional footprint

Old Second Bancorp, Inc. delivers full-service banking, including customary consumer and commercial products. This is anchored by Old Second National Bank, headquartered in Aurora, Illinois. As of September 30, 2025, the pro forma size reflected total assets of approximately $7.0 billion, with total deposits reaching $5.7 billion and total loans at $5.2 billion. The regional footprint includes operations in Kane, Kendall, DeKalb, DuPage, LaSalle, Cook, and Will Counties in Illinois, with 53 locations as of December 31, 2024.

The value proposition here is comprehensive service delivery:

• Customary consumer and commercial products and services.
• Electronic banking, including web and mobile banking.
• Safe deposit operations and corporate cash management.

Specialized lending products, including the new powersport loan segment

The loan portfolio is significantly enhanced by strategic acquisitions, bringing in specialized, higher-yielding assets. The new powersport loan segment, integrated through the Bancorp Financial acquisition, is a key differentiator. The acquired portfolio from Evergreen Bank Group showed strong yields, with powersports loans recording an average rate of 9.48% on Fourth Quarter 2024 originations. Total loans increased by $1.27 billion from the previous quarter, primarily due to the acquisition of $1.19 billion in loans with Bancorp Financial.

High Net Interest Margin (TE) of 5.05% in Q3 2025

A major financial value proposition is the bank's strong profitability on its lending activities relative to interest paid on deposits. For the third quarter of 2025, the tax equivalent net interest margin (TE) was 5.05%. This represented a 20 basis point increase from the second quarter of 2025 and a 41 basis point increase compared to the third quarter of 2024. Net interest and dividend income for Q3 2025 reached $82.8 million.

Here's a quick look at the margin performance:

Metric	Q3 2025 Value	Change from Q2 2025
Tax Equivalent Net Interest Margin (TE)	5.05%	+20 basis points
Net Interest and Dividend Income	$82.8 million	+28.9%

Dedicated Sponsor Finance division for middle-market companies

O2 Sponsor Finance, a division of Old Second National Bank, provides cash flow-based loans nationally to lower middle-market businesses. This division focuses on supporting private equity sponsors, independent sponsors, and family offices. Since 2005, the team has executed leveraged buyouts with over 100 private equity sponsors, closing more than $4.0 billion in loan commitments in the lower middle market. Target businesses typically have between $2 million and $10 million in EBITDA and revenues between $10 million and $100 million.

O2 Sponsor Finance offers specific products for these transactions:

• Senior Secured Credit Facilities.
• Term Loans.
• Revolving Lines of Credit.
• Delayed Draw Term Loans.

Comprehensive wealth management and trust services

Old Second Bancorp, Inc. extends its services beyond traditional lending and deposits to include fiduciary and advisory roles. The Bank provides trust services and wealth management services for individual, corporate, and not-for-profit clients. Richard A. Gartelmann, Jr. serves as Executive Vice President, Wealth Management. These services complement the core banking offerings, providing clients with a full spectrum of financial planning and asset stewardship.

Old Second Bancorp, Inc. (OSBC) - Canvas Business Model: Customer Relationships

You're looking at how Old Second Bancorp, Inc. keeps its customers engaged following the major integration of the Evergreen Bank Group, which finalized its systems conversion on October 20, 2025. The bank's foundation rests on deep, local connections.

Personal, relationship-based service through branch staff

The physical footprint is central to the relationship model. Following the acquisition and integration of Bancorp Financial's subsidiary, Old Second National Bank now operates across 55 locations throughout the Chicagoland area as of October 20, 2025. This expansion across Cook, DeKalb, DuPage, Kane, Kendall, LaSalle, and Will counties reinforces the commitment to community-centered service. The emphasis remains on relationships with individual customers and small to medium-sized businesses supported by branch staff.

Dedicated relationship managers for commercial and wealth clients

For commercial and higher-value clients, the model shifts from general branch support to focused attention. While the exact count of dedicated relationship managers isn't public, the structure supports this by segmenting services for commercial, industrial, and real estate lending opportunities. This structure is designed to maintain the high-touch service expected by these segments, which form a stable, loyal core deposit base.

Self-service digital and mobile banking platforms

The relationship strategy is augmented by modern digital access. Customers now have full access to Old Second's robust online and mobile banking platforms. This self-service layer provides convenience and flexibility for routine financial management, complementing the in-person service.

Here's a quick look at the scale and recent growth impacting the customer base and service delivery:

Metric	Value/Date	Context
Total Banking Locations (Post-Integration)	55 (October 2025)	Includes all former Evergreen Bank Group branches
Pro Forma Assets (Post-Merger Estimate)	$7.1 billion	Estimate following the merger agreement
Wealth Management Income Growth (QoQ)	$412,000 increase	Q3 2025 vs. Q2 2025
Core Business Segment	Community Banking	The single operating segment evaluated

High-touch advisory model for trust and wealth services

The trust and wealth management segment operates on a high-touch advisory model. This includes trust administration and services for personal and corporate trusts, plus employee benefit plan administration. The focus on advisory services is concrete: wealth management income saw a $412,000 increase in the third quarter of 2025 over the second quarter of 2025, driven by growth in advisory and estate planning. This growth in fee-based income confirms the traction of this specialized relationship approach. The bank also utilizes River Street Advisors, LLC, formed in May 2010, to provide investment advisory/management services.

If onboarding for new commercial clients takes longer than expected post-integration, relationship retention risk rises.

The physical network is anchored by the Old Second National Bank, which, following the July 1, 2025, merger with Bancorp Financial, Inc., operates 56 locations across Chicago's downtown, west, and south suburban markets as of the third quarter of 2025.

• Total Deposits as of September 30, 2025: $5.76 billion.

O2 Sponsor Finance direct origination team

The O2 Sponsor Finance division acts as a specialized channel, directly originating loans to lower middle market businesses across the United States, often in partnership with private equity sponsors. This team focuses on cash flow-based loans for leveraged buyouts, refinances, and recapitalizations. The division had a very busy second-half of 2025 with significant new financing activity reported as of December 1, 2025.

The division actively supports transactions, such as providing senior secured credit facilities for the acquisition of EventLink Group in December 2025 and Formula Corp in September 2025.

ATMs and third-party payment networks

While Old Second Bancorp, Inc. provides an extensive variety of services, specific, current figures for the total number of proprietary ATMs or the extent of their participation in third-party payment networks as of late 2025 are not explicitly detailed in the recent Q3 2025 financial disclosures. The bank's general service offering includes customary consumer products, which implicitly rely on standard ATM and payment infrastructure.

Old Second Bancorp, Inc. (OSBC) - Canvas Business Model: Customer Segments

You're looking at the customer base for Old Second Bancorp, Inc. (OSBC) right after integrating Bancorp Financial, which closed July 1, 2025. This combination significantly expanded their footprint across the Chicago area.

The combined entity, as of March 31, 2025, on a proforma basis, managed total assets of approximately $6.98 billion, with total loans reaching $5.09 billion, supported by $5.95 billion in deposits across 56 locations in the downtown, west, and south suburban Chicago market.

• The loan portfolio includes consumer lending, which saw growth post-acquisition.

Small-to-mid-sized businesses (SMBs) and commercial real estate investors

This group drives a significant portion of the commercial loan book. The loan portfolio composition shows growth in commercial and industrial (C&I) and commercial real estate-investor and construction portfolios. The acquisition from Bancorp Financial also introduced a new powersport loan segment.

Portfolio Segment (as of 06/30/2025 or Q3 2025 context)	Loan Balance Reference (in millions)	Latest Total Loans (09/30/2025)
Total Loans (Proforma 03/31/2025)	$5,090	-

The loan-to-deposit ratio stood at 91.4% as of September 30, 2025.

High-net-worth individuals utilizing wealth and trust services

This segment is served through trust services and wealth management offerings. While the absolute Assets Under Management (AUM) isn't explicitly stated for Q3 2025, the wealth management income saw a notable increase.

• Wealth management income increased by $412,000 in Q3 2025 compared to Q2 2025.
• Wealth management balances reported for Q2 2025 were $3,103 million.

Old Second Bancorp, Inc. (OSBC) - Canvas Business Model: Cost Structure

The Cost Structure for Old Second Bancorp, Inc. (OSBC) in late 2025 is heavily influenced by the recent acquisition of Bancorp Financial, Inc. and its subsidiary, Evergreen Bank Group, which closed on July 1, 2025. Noninterest expense for the third quarter of 2025 reached $63.2 million, representing a 60.7% increase compared to the third quarter of 2024. This period saw a net provision for credit losses of $19.7 million, which included the impact of the Bancorp Financial day two purchase accounting adjustments.

Here's a quick look at some key third quarter 2025 expense metrics:

Cost Component	Q3 2025 Amount	Comparison to Q2 2025
Noninterest Expense	$63.2 million	Increase of 45.5%
Net Provision for Credit Losses	$19.7 million	Increase from $2.5 million
Salaries and Employee Benefits Increase (QoQ)	$12.8 million	Primarily due to acquisition payouts

Interest expense on deposits and borrowings saw a notable increase following the acquisition. Compared to the third quarter of 2024, total interest expense increased by $5.8 million. Quarter-over-quarter, interest expense on average interest-bearing liabilities rose by $10.3 million from the second quarter of 2025, driven by higher deposit and borrowing balances assumed in the merger.

Personnel and compensation costs are now spread across an expanded footprint. Following the integration completion on October 20, 2025, former Evergreen customers gained access to Old Second's network of 55 locations across the Chicagoland area. The third quarter 2025 noninterest expense included a $12.8 million increase in salaries and employee benefits compared to the linked quarter, with $8.4 million of that increase directly attributable to change in control, retention, and severance payouts related to the Bancorp Financial acquisition. This reflects the immediate cost of integrating the larger workforce.

You should track these cost drivers closely:

• Acquisition-related noninterest expense, including transaction costs.
