Old National Bancorp (ONB) Company Overview

What does Old National Bancorp do?

Old National Bancorp is the Nasdaq-listed holding company for Old National Bank, a regional banking franchise rooted in Evansville, Indiana. The company serves consumers, small businesses, middle-market companies, municipalities, nonprofits, and affluent households across a broad Midwestern and Southeastern footprint. Its core offering is conventional banking—deposits, commercial and consumer loans, treasury management, mortgages, and payment services—supplemented by wealth management and capital-markets capabilities. The company’s official profile describes Old National as a top-25 U.S. banking company and, after its 2025 combination with Bremer Financial, approximately a $73 billion-asset institution.

Why does the franchise matter?

Regional banks live or die by the quality and stability of their funding base. Old National’s relevance comes from combining community-bank relationships with enough scale to support specialized commercial lending, treasury services, wealth advice, technology investment, and regulatory infrastructure. The company says it is the fifth-largest commercial bank headquartered in the Midwest on a pro forma basis as of May 6, 2026. That scale is not merely a ranking: it affects the breadth of products the bank can offer, the cost of compliance, the ability to spread technology spending across a larger customer base, and the capacity to retain commercial clients as their needs become more complex. The official company overview also links the modern institution to a banking history beginning in 1834, which supports brand recognition and local trust in markets where deposits are relationship-driven.

How does Old National Bancorp make money?

Old National’s economics are built around the spread between what it earns on loans and securities and what it pays for deposits and wholesale funding. This net interest income is the dominant revenue source. Fee income from wealth management, capital markets, mortgage banking, service charges, cards, and other banking activities adds diversification, but it remains secondary to spread income. In the first quarter of 2026, fully taxable-equivalent net interest income was $580.4 million, while total noninterest income was $122.3 million. That means roughly four-fifths of quarterly revenue before the credit provision came from the interest spread.

What drives the spread?

The key variables are loan growth, asset yields, deposit mix, deposit pricing, securities reinvestment, and the shape of the interest-rate curve. Old National ended Q1 2026 with $49.7 billion of loans and $55.7 billion of deposits. Its loan-to-deposit ratio was 89%, indicating that deposits funded most lending while leaving room for securities and other liquidity sources. The company reported a 3.55% fully taxable-equivalent net interest margin, down 10 basis points sequentially, as lower asset yields outweighed the benefit of loan growth and cheaper funding. Deposit costs fell to 1.72%, while interest-bearing deposit costs declined to 2.24%.

Which fee lines improve revenue quality?

Fee revenue matters because it can reduce dependence on interest rates, but it is not equally stable. Wealth-management fees are generally recurring and linked to assets under management, while capital-markets and mortgage fees can be more cyclical. In Q1 2026, management said strong wealth fees were offset by seasonally lower bank fees and weaker capital-markets and mortgage fees. Researchers should therefore separate recurring relationship fees from transaction-sensitive revenue rather than treating all noninterest income as equally durable.

What did the latest quarter show?

The quarter ended March 31, 2026 showed a bank with solid loan growth, strong profitability, lower funding costs, and manageable but visible credit costs. Old National reported $229.6 million of net income applicable to common shareholders, or $0.59 per diluted share. Adjusted net income was $237.7 million, or $0.61 per diluted share. The difference reflected $7.3 million of merger-related charges and $3.4 million of expense tied to distribution of excess pension assets.

Why did operating efficiency improve?

Reported noninterest expense was $364.7 million and adjusted noninterest expense was $354.0 million. The adjusted efficiency ratio reached 45.7%, compared with 46.0% in Q4 2025, as Old National realized the full targeted Bremer cost savings and maintained expense discipline. For a bank, a lower efficiency ratio means fewer operating costs are required to generate each dollar of revenue. The Q1 result therefore indicates meaningful operating leverage even though net interest income dipped. The official first-quarter 2026 earnings release provides the detailed GAAP and adjusted reconciliations.

How did mergers reshape Old National’s strategy?

Old National’s modern form is the result of repeated expansion through bank combinations. Mergers increased deposits, loans, geographic reach, and fee capabilities, but they also created integration risk, goodwill, restructuring charges, and a larger regulatory burden. The strategic question is not whether the company can become larger; it is whether acquired relationships and cost savings can produce durable per-share returns without weakening credit discipline.

What did Bremer change financially?

The Bremer transaction closed May 1, 2025 and explains much of the year-over-year jump in Old National’s balance sheet. Assets rose from $53.6 billion at year-end 2024 to $72.2 billion at year-end 2025; loans rose from $36.3 billion to $48.8 billion; deposits increased from $40.8 billion to $55.1 billion; banking centers expanded from 280 to 346; and full-time-equivalent employees rose from 4,066 to 4,971. Those figures show why comparisons across 2025 require care: much of the growth was acquisition-driven rather than purely organic. The merger agreement and transaction mechanics are documented in Old National’s official Bremer merger filing.

How strong are deposits, credit quality, and capital?

For a regional bank, financial strength is better judged through funding, credit, capital, and liquidity than through revenue growth alone. Old National’s Q1 2026 balance sheet showed $55.7 billion of deposits funding $49.7 billion of loans, a loan-to-deposit ratio of 89%. Total borrowed funds were $7.8 billion, and total shareholders’ equity was $8.5 billion. The bank’s preliminary common equity Tier 1 ratio was 11.11%, Tier 1 capital ratio was 11.56%, total capital ratio was 13.71%, and tangible common equity to tangible assets was 7.67%.

What do the credit metrics say?

Net charge-offs were $32.0 million in Q1 2026, equal to 0.26% of average loans on an annualized basis. Excluding purchased-credit-deteriorated loans that carried acquisition-date allowances, the ratio was 0.19%. Loans 30 or more days past due were 0.24% of total loans, while nonaccrual loans were 1.03%. The allowance for credit losses, including unfunded commitments, represented 1.22% of end-of-period loans. None of those metrics eliminates downside risk, but together they show a loan book that remained controlled after several acquisitions.

What gives Old National a competitive advantage?

Old National’s strongest advantage is not a patented product. It is the combination of local relationships, a broad deposit franchise, commercial banking expertise, and enough scale to fund technology and specialized services. Deposits are often sticky because customers use linked operating accounts, treasury-management tools, payroll services, credit lines, and personal banking. That creates switching costs that are operational rather than contractual. The larger franchise can also offer clients capital-markets support, wealth advice, and more sophisticated risk management without abandoning local coverage.

Where does scale create value?

Scale spreads fixed investments over more customers and transactions. Cybersecurity, regulatory reporting, data infrastructure, digital banking, fraud controls, treasury platforms, and specialist lenders are expensive capabilities. A $73 billion-asset bank can justify those investments more easily than a small community institution. It can also underwrite larger commercial relationships and retain clients that might otherwise migrate to national banks. However, scale only becomes an advantage when integration is disciplined; duplicated systems, cultural friction, or customer attrition can erase merger benefits.

Who are the main competitors?

Old National competes simultaneously with national banks, large regional institutions, local community banks, credit unions, mortgage lenders, wealth managers, fintech platforms, and nonbank commercial lenders. In many Midwestern markets, relevant competitors include U.S. Bancorp, Fifth Third Bancorp, Huntington Bancshares, KeyCorp, Regions Financial, BMO, and numerous local banks. National banks may have greater technology and product budgets; community banks can compete on intimacy and speed; fintechs can target narrow products with low overhead. Old National’s positioning is therefore a middle path: broader products than a small bank, but a more local relationship model than the largest national institutions.

Who owns Old National stock, and why does governance matter?

Old National has a conventional one-share, one-vote common-stock structure. As of the March 20, 2026 proxy record date, 386.3 million common shares were outstanding. The company identified three holders above 5%: Otto Bremer Trust, BlackRock, and FMR. The trust became a major shareholder through the Bremer transaction, which gives the ownership profile an unusual strategic dimension: one of the acquired bank’s legacy owners remained a substantial economic stakeholder after closing.

How are incentives and capital returns connected?

The 2026 board slate contained 12 directors, and James Ryan served as chairman and chief executive officer. The proxy emphasizes executive stock ownership and performance-linked compensation, which is intended to connect management with per-share outcomes. Capital allocation provides a practical test. Old National repurchased 3.9 million shares during Q1 2026 and separately disclosed a February 2026 repurchase of 1.9 million shares from Otto Bremer Trust for approximately $50.0 million. Buybacks can improve per-share metrics when made below intrinsic value, but they also compete with loan growth, technology spending, acquisitions, and capital buffers. The 2026 proxy statement is the primary official source for ownership, board composition, and compensation governance.

Which KPIs best explain performance?

A useful bank analysis focuses on a small number of linked metrics. Net interest margin measures spread economics. Deposit cost reveals funding pressure. Loan growth shows whether the bank can deploy capital. Credit metrics indicate whether growth is creating future losses. Efficiency measures the operating cost of producing revenue. Capital ratios show the loss-absorption cushion, while tangible book value tracks common equity after removing goodwill and other intangibles.

How should students connect the metrics?

The metrics form a chain. Deposit gathering influences funding cost; funding cost and asset yield determine net interest margin; margin and fee revenue determine revenue; expenses determine pre-provision profit; credit losses then reduce earnings; and retained earnings rebuild capital. For example, Q1 2026’s 10-basis-point NIM decline would normally pressure earnings, but loan growth, stronger reported fee income, lower adjusted expenses, and share repurchases helped diluted EPS rise to $0.59. A single KPI therefore rarely explains the whole quarter.

What risks could weaken Old National’s outlook?

The largest risks are interconnected. Interest-rate shifts can compress margin or reduce securities values. Economic weakness can reduce loan demand and increase charge-offs. Deposit competition can force the bank to pay more for funding. Acquisitions can create integration problems or expose the company to underestimated credit marks. Cybersecurity and vendor failures can disrupt operations and damage trust. Regulatory changes can increase capital, liquidity, compliance, or resolution-planning costs.

Which risk is most important now?

The most immediate analytical tension is balancing loan growth and capital returns against the need to protect credit and capital through a changing rate and economic cycle. Old National grew period-end loans by $970.9 million in Q1 2026, an 8.0% annualized pace, while repurchasing 3.9 million shares. That combination can create attractive per-share growth when underwriting remains sound, but it leaves less room for error if credit losses rise faster than expected. The company’s 2025 Form 10-K details the broader interest-rate, credit, liquidity, operational, regulatory, cybersecurity, and merger-related risk framework.

Why does Old National matter for valuation?

A bank DCF or residual-income analysis should begin with normalized earnings power rather than headline revenue growth. Old National’s valuation depends on sustainable net interest income, recurring fee revenue, credit costs, expense efficiency, capital requirements, and the rate at which tangible book value compounds. The Bremer transaction complicates historical comparisons because it added a large block of assets, deposits, loans, goodwill, branches, and shares. Analysts should therefore distinguish organic growth from acquisition effects and reported results from adjusted figures.

Which assumptions drive intrinsic value?

The 2025 annual baseline provides useful context: net income applicable to common shareholders was $653.1 million, diluted EPS was $1.79, full-year fully taxable-equivalent net interest income was $2.09 billion, noninterest income was $466.5 million, and the annual NIM was 3.54%. The year-end balance sheet held $72.2 billion of assets, $48.8 billion of loans, and $55.1 billion of deposits. Those figures are available in the company’s full-year 2025 results. A defensible model should use normalized post-integration expenses and credit costs rather than simply annualizing the strongest quarter.

What should students and investors monitor next?

The next phase of the Old National story is about proving that scale creates durable per-share value. The company has largely moved beyond announcing the Bremer combination and into demonstrating customer retention, organic loan growth, stable deposits, disciplined credit, and sustainable cost savings. The following indicators provide a concise monitoring dashboard.

What is the key takeaway?

Old National’s official investor-relations site and SEC filing page provide the next earnings releases, quarterly reports, ownership filings, and governance updates needed to test that conclusion.
