Old National Bancorp
Business Overview: Old National Bancorp (NASDAQ: ONB)
Executive Summary
Old National Bancorp is an Indiana-incorporated financial holding company and the parent of Old National Bank, a national bank founded in 1834 and headquartered in Evansville, Indiana, with its commercial and consumer banking leadership based in Chicago. Old National describes itself as the sixth-largest Midwestern-headquartered bank by asset size, operating roughly 258 banking centers across Illinois, Indiana, Iowa, Kentucky, Michigan, Minnesota, and Wisconsin.
With $49.1 billion in total assets at year-end 2023, Old National is a true super-regional bank built largely through acquisition, most recently the pending all-stock purchase of CapStar Financial (~$344 million, ~$3.3 billion in assets, expected to close in Q2 2024). The bank generates revenue primarily from net interest income on loans and investment securities, supplemented by wealth management, trust, treasury management, and capital markets fees.
1. Core Business Model & How They Work
Old National operates the standard regional-bank value chain: it gathers low-cost deposits across its Midwest branch footprint, deploys that funding into consumer and commercial loans and securities, and earns the spread (net interest income), while cross-selling fee-based wealth, treasury, and capital-markets services.
[ Deposit Gathering (Branches, Digital) ] ➡️ [ Loan Origination (Consumer/Commercial/CRE) ] ➡️ [ Net Interest Margin Capture ] ➡️ [ Fee Income (Wealth, Treasury, Capital Markets) ] ➡️ [ Periodic Bolt-On M&A (e.g., CapStar) ]Key Operational Drivers
- Branch-based deposit franchise: 258 banking centers anchored by strong share in Chicago (43.3% of deposits), Evansville (10.5%), Minneapolis-St. Paul (9.9%), Indianapolis (5.3%), and Milwaukee (3.5%).
- Disciplined M&A: Old National has grown into a super-regional bank largely through acquisitions, with CapStar Financial the latest example, while also divesting non-core businesses (it sold its health savings account custodial business in 2022 for a $90.7 million pre-tax gain).
- Diversified lending: a mix of commercial, commercial real estate, residential mortgage, home equity, consumer, and agricultural lending.
- Fee-income diversification: wealth management, trust, brokerage, capital markets, treasury management, and merchant services supplement interest income.

Banking Services- Consumer & Residential Banking: Home equity lines, residential mortgages, consumer loans, and deposit/digital banking products.
- Commercial & CRE Lending: Commercial and commercial real estate loans, agricultural loans, letters of credit, and lease financing — a segment the bank flags as a notable concentration risk.
- Wealth, Trust & Capital Markets Services: Wealth management, trust and investment advisory, brokerage, treasury management, merchant services, and foreign currency services.
3. Product Portfolio & Key Offerings
| Product/Service | Category | Purpose | Why It Matters |
|---|---|---|---|
| Commercial & CRE loans | Lending | Financing for Midwest businesses and real estate | Core earning-asset category; also a flagged concentration risk |
| Residential mortgage & home equity | Lending | Consumer home financing | Broad-based, relationship-building consumer product |
| Deposit accounts (checking, savings, money market, time deposits) | Funding | Low-cost funding base for loans | Chicago alone supplies 43.3% of total deposits |
| Wealth management & trust | Fee income | Investment advisory and fiduciary services | Diversifies revenue beyond interest-rate-sensitive banking |
| Treasury management & merchant services | Fee income | Cash management for business clients | Sticky, relationship-deepening commercial product |
4. Competitive Landscape
Old National competes against a broad range of financial services providers across its Midwest footprint:
- Commercial banks and thrifts of similar or larger size, including national banks with greater resources
- Credit unions, which often have tax and cost advantages
- Mortgage companies and consumer finance firms
- FinTechs and out-of-market digital lenders, which can originate loans without a physical branch presence
- Brokerages, insurers, and money market funds, competing for wealth and deposit dollars
The filing explicitly notes that some competitors are larger, better capitalized, or subject to fewer regulatory constraints, and that digital-only competitors are intensifying pressure on traditional deposit-gathering.
5. Strategic Strengths & Risks
Strengths (Moat Sources)
- A large, geographically concentrated branch network (258 centers) that anchors a low-cost, sticky deposit base, led by a dominant Chicago presence.
- Scale: at $49.1 billion in assets, Old National is large enough to absorb regulatory and technology costs that burden smaller community banks, while still being nimble enough to compete for regional relationships.
- Regulatory barriers to entry: maintaining financial holding company status requires staying "well capitalized" and "well managed," and acquisitions require Federal Reserve or OCC approval — barriers that protect incumbents more than they create a moat outright.
- A demonstrated ability to execute bank M&A (CapStar Financial) to add scale in attractive markets.
Risks
- Geographic/economic concentration in the Midwest, with a weighted-average population change of (0.7)% from 2020–2024 versus a 1.4% national average, signaling a slower-growth footprint than the national economy.
- Commercial real estate concentration, a sector facing broad industry scrutiny amid higher rates and post-pandemic office demand shifts.
- Merger integration and regulatory approval risk tied to the pending CapStar acquisition.
- Deposit concentration in Chicago (43.3%), which cuts both ways as a strength and a single-market risk.
- Regulatory cost pressure, including a $19.1 million FDIC special assessment and proposed CFPB overdraft and interchange-fee rules that could compress fee income.
- Holding-company dependence on bank dividends, a structural feature of the bank holding company model.
6. Financial Overview
| Metric | Value (period) | Strategic Context |
|---|---|---|
| Total assets | $49.1 billion (12/31/2023) | Super-regional scale; sixth-largest Midwestern-headquartered bank by Old National's own description |
| Net income | $449.5 million (nine months ended 9/30/2023) | Run-rate roughly $150 million/quarter, reflecting consistent profitability |
| Net interest income (GAAP) | $1.14 billion (nine months ended 9/30/2023) | Primary revenue driver; sensitive to rate environment and deposit costs |
| Efficiency ratio | ~51.9% (nine months ended 9/30/2023) | A sub-55% efficiency ratio is generally viewed as cost-efficient for a regional bank |
| Return on average assets (ROAA) | ~1.25% (nine months ended 9/30/2023) | Comfortably above the ~1.0% level often used as a profitability benchmark for banks |
| Net interest margin (FTE) | ~3.59% (nine months ended 9/30/2023) | Solid margin reflecting a favorable deposit mix, though sensitive to further rate moves |
| Total deposits | $37.3 billion (9/30/2023) | Core funding base for the loan portfolio |
| Total loans | $32.6 billion (9/30/2023) | Reflects a loan-to-deposit ratio of roughly 87%, leaving room for continued loan growth |
7. Summary Conclusion
Old National Bancorp is a well-capitalized, acquisitive Midwest super-regional bank whose moat rests on a large, geographically concentrated deposit franchise, scale-driven cost efficiency (sub-52% efficiency ratio), and the general regulatory barriers that protect incumbent banks. Its business model of gathering low-cost deposits, deploying them into diversified consumer and commercial loans, and layering on fee income from wealth and treasury services has produced consistent double-digit ROE-adjacent profitability. The biggest forward risks are its concentration in a slower-growing Midwest footprint and in commercial real estate lending, along with execution risk on the pending CapStar Financial integration — risks common to the regional banking sector rather than unique to Old National.
