Old National Bancorp (ONB), a Midwest-focused regional bank with a footprint spanning 15 states, has been on a transformative journey over the past decade, marked by strategic acquisitions that supercharged its scale. Trading at levels that leave room for appreciation—analyst price targets pencil in roughly 1% to 21% upside from the most recent close—the stock reflects a market still digesting post-merger integration and lingering caution from the 2023 regional banking turbulence. Yet, beneath the surface, ONB’s fundamentals paint a picture of resilient growth, improving per-share metrics, and a leadership team navigating higher-for-longer interest rates with discipline. The 2022 merger with First Midwest Bank was a pivotal chapter, doubling revenue overnight and positioning ONB as a top-25 U.S. bank by assets, but it also introduced margin pressures and dilution that the company is steadily resolving.
The Merger Catalyst: Revenue Rocket Fuel Amid Integration Headwinds
ONB’s story truly accelerates in 2022, when revenue exploded from $853 million in 2021 to $1.85 billion (+117%), driven by the First Midwest acquisition. This wasn’t just additive; it reflected synergies in branch networks and loan portfolios, boosting employees from 2,374 to 3,967 (+67%) and revenue per employee from $359,000 to $467,000 (+30%). By 2024, revenue hit $2.96 billion, up another 16% from 2023’s $2.54 billion, underscoring operational leverage. Revenue per share tells a similar tale of efficiency gains, climbing from $5.16 in 2021 to $9.55 in 2024 (+85%), even as shares outstanding swelled post-merger from 165 million to 309 million (+87%).
However, this growth came with trade-offs. Gross margin dipped sharply from 95% in 2021 to 72% in 2023 and 64% in 2024, a 33% relative decline, likely tied to merger-related expenses, deposit cost inflation during the Fed’s rate-hiking cycle, and the 2023 banking scares that spiked funding costs industry-wide. Earnings before taxes (EBT) held steady, rising from $339 million in 2021 to $680 million in 2024 (+101%), but EBT margin compressed to 23% in 2024 from peaks near 40%, highlighting the importance of net interest margins (NIM) in banking—where every basis point counts toward profitability amid volatile rates. Net income followed suit, peaking at $582 million in 2023 before a 2024 dip to $539 million (-7%), possibly reflecting one-time charges, yet ROE remained robust at 9.1% in 2024, down slightly from 11.1% but still above pre-merger levels of 9.3% in 2021.
Stock price action mirrored this evolution unevenly. Annual highs trended upward—from $21 in 2021 to $24 in 2024 (+14%)—but lows fluctuated, dipping to $11-15 amid 2020 COVID fears and 2023’s SVB/Signature Bank fallout, which hammered regional lenders on unrealized losses in bond portfolios. ONB’s shares held firmer than peers, with 2024 highs at $24 (+18% from 2023 highs), signaling investor confidence in its deposit-rich franchise (critical for liquidity during stress).
Valuation: Cheap on Fundamentals, Room to Re-Rate
ONB trades at discounts that scream value, especially post-merger. The trailing PE ratio hovered in the low teens—12.9 in 2024, up from 8.8 in 2023—reasonable for a bank with mid-teens EPS growth, as it balances growth against cyclical risks. Why does PE matter here? It gauges how much investors pay for each dollar of earnings; ONB’s sub-13x multiple versus historical banks’ 15x average suggests undervaluation, particularly with EPS forecasted to jump to $1.79 in 2025 (+6% from 2024’s $1.68) and $2.59 in 2026 (+45%). PS ratio compressed from 3.5 in 2021 to 2.3 in 2024 (-34%), a boon as revenue scales faster than market cap, while PB ratio stabilized around 1.1x, aligning book value per share growth from $18.24 in 2021 to $20.49 in 2024 (+12%).
Free cash flow per share offers another lens: it surged to $2.84 in 2022 post-merger before moderating to $1.92 in 2024, supporting dividends (yield ~3-4% historically) and buybacks. EV/FCF around 19x reflects a healthy balance, not distressed. Compared to stock performance, multiples contracted as prices lagged revenue—e.g., PS fell while highs rose modestly—implying the market hasn’t fully credited merger synergies yet.
Balance Sheet Fortress in a Stormy Sector
ONB’s capital stack is a storyteller’s dream of prudent expansion. Shareholders’ equity ballooned from $3.01 billion in 2021 to $6.34 billion in 2024 (+111%), outpacing total debt’s rise from $2.62 billion to $5.14 billion (+96%). Net debt grew but remains manageable at 62% of equity, with ROIC at 4.2% in 2024 (down from 5% peak but above 3% pre-merger), measuring how efficiently invested capital generates returns—key for banks funding loans. Working capital swings negative (typical for deposit-heavy models) stabilized post-2023 at -$3.15 billion, bolstered by $622 million in 2024 operating cash flow (+20% from 2023).
ROA and ROE—vital efficiency metrics—stayed consistent: ROA ~1%, ROE 9-11%, outperforming smaller peers strained by 2023’s rate shocks. The First Midwest deal, closed amid post-COVID M&A frenzy, diversified deposits (now ~$45B+), cushioning ONB during the March 2023 liquidity crunch when rivals faltered.
Insider Signals: Cautious but Not Alarming
Insider activity has been muted, with zero buys across recent months and only two notable sells: the President/COO offloading 67,343 shares in May 2025 (part of a planned 10b5-1 transaction) and the General Counsel selling 30,000 shares in February 2026. Total sell proceeds topped $2.2 million, but no frantic dumping—common in diversified exec compensation strategies. Absent buys, it tempers enthusiasm, yet aligns with a board focused on integration over personal accumulation. Correlationally, sells coincided with price stability, not panic.
Charting the Horizon: Analyst Optimism Meets Execution Risks
Looking ahead, analysts forecast revenue acceleration to $3.74 billion in 2025 (+26% from 2024), tapering to $2.91 billion in 2026 (possibly conservative modeling), with net income rebounding to $999 million in 2026 (+85% from 2024) and $1.07 billion in 2027 (+7%). EPS climbs to $2.83 by 2027 (+68% from 2024), fueled by NIM expansion as rates peak and deposits reprice. Shares dilute further to 390 million, but book value per share hits $23.37 in 2025 (+14%), supporting PB stability.
Price targets cluster with the low end just 1% above recent levels, average implying 13% upside, and high at 21%—a consensus betting on 10%+ EPS growth and dividend hikes. Risks loom: prolonged high rates could squeeze margins further (EBT margin dips to 23% in 2024), recession might hike provisions, or regulatory scrutiny post-New York Community Bancorp’s woes could weigh. Yet, ONB’s culture—rooted in community banking with tech investments—positions it well. Leadership, under CEO Jim Sandgren since 2010, has delivered 10%+ CAGR in EPS pre-merger; post-deal execution could unlock that again.
In narrative terms, ONB is the underdog regional that’s bulked up without losing its edge. Stock price has traced a volatile but upward arc (+30% from 2020 lows to recent highs), lagging revenue tripling but poised to catch up if ROE sustains 10%+ and buybacks resume (capex/share minimal at -0.09). For patient investors, it’s a tale of merger magic maturing into compound returns—watch NIM recovery and insider buying as plot twists.
