This October 27, 2025 report presents a deep-dive analysis of Old Second Bancorp, Inc. (OSBC), examining its business model, financials, past performance, future growth, and fair value. Our evaluation benchmarks OSBC against six competitors, including Wintrust Financial Corporation (WTFC) and First Busey Corporation (BUSE), with all insights distilled through the investment philosophy of Warren Buffett and Charlie Munger.
Mixed outlook for Old Second Bancorp.
The bank has grown significantly through a major acquisition, boosting its balance sheet and core income.
However, a massive $19.65 million provision for potential loan losses recently caused net income to fall by 57%.
Operational efficiency has also worsened considerably, a key concern for its traditional community banking model.
The stock appears fairly valued based on expected earnings, but past shareholder dilution to fund growth is a notable risk.
Future performance will likely depend more on disciplined cost control than on expansion in its competitive market.
Investors should monitor for improved profitability and efficiency before considering this stock.
US: NASDAQ
Old Second Bancorp, Inc. (OSBC) operates a straightforward, relationship-focused community banking model. Headquartered in Aurora, Illinois, the company provides a comprehensive range of banking and financial services primarily to individuals, small-to-medium-sized businesses, and local municipalities across the Chicago metropolitan area, including the affluent collar counties. Its core business involves gathering deposits from the local community through its network of branches and using those funds to originate loans. The bank's main revenue streams are generated from the interest rate spread between its loans and deposits (net interest income) and, to a lesser extent, from fees for services like wealth management, deposit accounts, and mortgage banking (noninterest income). OSBC's primary product lines can be categorized into commercial lending, residential lending, wealth management, and deposit services, which together account for the vast majority of its revenue and operations.
The most significant contributor to OSBC's revenue is its commercial lending operation, which is the primary driver of its net interest income. This segment includes commercial and industrial (C&I) loans to businesses for working capital and expansion, owner-occupied commercial real estate (CRE) loans, and non-owner-occupied CRE loans for investors. As of year-end 2023, these commercial loans collectively represented over 75% of the bank's total loan portfolio, with non-owner-occupied CRE alone comprising a substantial 38%. The market for commercial lending in the Chicago area is mature and intensely competitive, with OSBC facing off against giant money-center banks like JPMorgan Chase, super-regional players like Wintrust Financial, and numerous other community banks. Competitors like Wintrust are significantly larger and offer a more diversified product set, while others like Byline Bancorp have a more specialized focus on government-guaranteed lending. OSBC's target customers are local business owners and real estate developers who value personalized service and quick decision-making from bankers who understand the local market. The stickiness of these relationships is moderate to high, as switching banks involves significant effort and the loss of an established relationship. The competitive moat for this product line is narrow, built almost entirely on local knowledge and customer relationships rather than scale or cost advantages. The heavy concentration in CRE, particularly non-owner-occupied properties, represents a key vulnerability, as this sector is sensitive to economic downturns and interest rate fluctuations.
Wealth management services represent OSBC's most differentiated and arguably strongest product line, contributing a significant and stable source of fee income. Through its Old Second Wealth Management division, the bank offers trust, investment management, and retirement planning services to high-net-worth individuals and institutions. In the first quarter of 2024, wealth management fees were $4.5 million, accounting for nearly a third of the bank's total noninterest income, a much more stable and high-margin revenue source than lending. The market for wealth management is also competitive, populated by independent registered investment advisors (RIAs), brokerage firms like Edward Jones, and the private banking arms of large national banks. However, OSBC's long-standing presence in its communities gives its trust department a powerful legacy advantage. Customers are typically affluent individuals and families within the bank's geographic footprint, and their relationships with wealth advisors are built on deep trust, often spanning generations. This creates very high switching costs, as clients are reluctant to move complex financial plans and personal trust to a new, unproven advisor. This high degree of customer stickiness gives the wealth management business a durable, albeit local, competitive moat that is difficult for competitors to replicate and provides a valuable source of diversified, high-quality earnings.
On the other side of the balance sheet, OSBC's deposit services are the foundation of its lending operations. The bank gathers funds through a standard suite of products, including noninterest-bearing checking accounts, savings accounts, money market accounts, and certificates of deposit (CDs). These deposits are sourced from the same retail and commercial customers that utilize the bank's lending and wealth services. The competition for low-cost core deposits is fierce, coming from every conceivable angle: national banks with huge marketing budgets, other community banks, local credit unions, and online-only banks offering high-yield savings accounts. OSBC's primary advantage in this area is its physical branch network, which provides convenience and a sense of security for many local depositors. As of the first quarter of 2024, noninterest-bearing deposits made up ~28% of total deposits, a decent but not exceptional figure that represents a source of very cheap funding. The stickiness of these deposit customers is moderate; while many people are hesitant to go through the hassle of switching their primary checking account, they are increasingly willing to move savings to capture higher yields elsewhere. Therefore, OSBC's moat in deposit gathering is modest, relying on its local brand and physical presence to maintain a stable, albeit not the lowest-cost, funding base.
In conclusion, Old Second Bancorp's business model is that of a quintessential community bank, with a moat that is narrow and geographically constrained. Its core lending business is a necessary but undifferentiated operation that thrives on local relationships but faces constant competitive pressure and is exposed to concentration risk in commercial real estate. The bank's resilience is significantly enhanced by its strong wealth management division, which serves as a critical diversifier, generating stable, high-margin fee income from a very sticky customer base. This division represents the company's most defensible competitive advantage.
Overall, the durability of OSBC's business model depends heavily on the economic health of the Chicago suburbs and its ability to defend its relationship-based turf against larger, better-capitalized rivals. While the bank is a well-established local institution, it lacks the scale, niche focus, or cost advantages that would constitute a wide moat. Its long-term success will hinge on prudently managing its real estate exposure while continuing to grow its high-quality wealth management business. The business model appears resilient enough to navigate normal economic cycles but could face challenges in a severe regional downturn due to its geographic and loan portfolio concentrations.
A review of Old Second Bancorp's recent financial statements reveals a bank in transition, likely due to a significant acquisition that closed between the second and third quarters of 2025. This is evidenced by the substantial jump in total assets from $5.7 billion to $7.0 billion and the corresponding increase in loans, deposits, and goodwill. On the income statement, this expansion drove strong top-line growth, with net interest income rising to $82.8 million in Q3 2025. However, this positive development was completely overshadowed by significant negative trends. Most notably, the provision for credit losses surged to $19.65 million from just $2.5 million in the prior quarter, suggesting a major reassessment of credit risk in the newly combined loan portfolio.
Profitability metrics have deteriorated sharply as a result. Net income fell to $9.9 million in Q3 from $21.8 million in Q2, and the return on assets dropped to a weak 0.62%. The bank's efficiency also suffered, with the efficiency ratio (costs as a percentage of revenue) climbing to over 66% in the latest quarter, a significant decline from the more favorable 57.8% in the prior quarter and 56.1% for the full year 2024. This was driven by a large increase in noninterest expenses, particularly salaries, which is typical after an acquisition but highlights a key challenge for management to control costs and realize expected synergies.
The balance sheet, while larger, shows some signs of stability. The loan-to-deposit ratio stands at a reasonable 90.1%, indicating that loan growth is adequately funded by core deposits. The tangible common equity to total assets ratio is solid at 10.18%, suggesting a decent capital buffer against potential losses. However, the massive increase in provisions for loan losses is a significant red flag that cannot be ignored. Until the bank demonstrates it can manage the credit quality of its expanded loan book and control its higher cost base, its financial foundation appears riskier than it did previously, despite its larger scale.
Over the last five fiscal years (FY2020–FY2024), Old Second Bancorp underwent a significant transformation, primarily driven by a large acquisition that closed in 2022. This event reshaped the bank's performance profile, leading to a much larger balance sheet and higher baseline earnings, but also introduced significant volatility into its historical metrics. Before the acquisition, OSBC was a smaller bank with modest performance. Post-acquisition, the bank's scale and profitability metrics improved, but its track record remains marked by the lumpiness of this inorganic growth rather than steady, organic execution.
Analyzing growth and profitability, the bank's revenue surged from $118.8 million in FY2020 to $271.8 million in FY2024, with a massive 84% jump in FY2022 alone. This was accompanied by a 47% increase in shares outstanding, a key detail for investors. Consequently, EPS growth has been erratic, with figures over the last five years of -29%, +129%, +36%, and -7%. While the absolute EPS level is higher, this inconsistency is a weakness. Profitability has improved, with Return on Equity (ROE) moving from below 10% to a range of 13-17% in recent years. However, its Return on Assets (ROA) of around 1.1% and efficiency ratio consistently above 60% are metrics that, according to peer comparisons, lag more efficient regional banks like Mercantile Bank or Lakeland Financial.
From a cash flow and shareholder return perspective, the record is also mixed. The company has generated consistently positive and growing operating cash flow, rising from $26 million in 2020 to $131.5 million in 2024, which is a sign of a healthy core operation. Capital returns, however, tell two different stories. On one hand, the dividend per share has grown aggressively, from just $0.04 in 2020 to $0.21 in 2024, all while maintaining a very low and safe payout ratio (typically under 15%). On the other hand, the significant share issuance in 2022 for the acquisition heavily diluted existing shareholders, and share buybacks have been minimal since. This prioritizes growth through acquisition over direct per-share returns to existing owners.
In conclusion, OSBC's historical record shows a management team capable of executing a large, transformative acquisition to build scale. The bank is more profitable today than it was five years ago. However, the performance is not one of consistent, best-in-class execution. The track record is defined by inorganic leaps rather than steady improvement, and its operational efficiency has not yet caught up to high-quality peers. This history suggests a company that has grown but has yet to prove it can be a top-tier operator.
The regional and community banking industry is undergoing a period of significant transformation, with the next 3-5 years expected to be defined by consolidation, technological adoption, and a fierce battle for low-cost deposits. The market is mature, with overall loan growth projected to track nominal GDP, likely in the 2-4% range annually. Key shifts driving this change include: 1) Increased regulatory scrutiny following the 2023 banking failures, which raises compliance costs and favors larger institutions with more resources. 2) The persistent shift to digital banking, which pressures banks to invest heavily in technology to meet customer expectations and reduces the traditional advantage of physical branches. 3) An altered interest rate environment, where higher rates have made customers more price-sensitive, leading to intense competition for deposits and compressing net interest margins. Catalysts for demand in the Midwest could include reshoring of manufacturing and government infrastructure spending, which would boost commercial loan demand. However, competitive intensity remains incredibly high. While high capital and regulatory requirements make starting a new bank difficult, existing players, including large national banks, aggressive super-regionals, and nimble fintechs offering specialized services, create a challenging environment for smaller community banks like Old Second.
The industry's structure is trending towards fewer, larger players. The number of community banks in the U.S. has been declining for decades, a trend expected to continue due to the powerful forces of scale. Larger banks can spread the high fixed costs of technology and compliance over a broader asset base, giving them a significant cost advantage. They can also offer a wider array of products and services. This dynamic makes mergers and acquisitions a primary growth strategy for banks of Old Second's size. To survive and thrive, community banks must either develop a defensible niche, achieve superior operational efficiency, or become adept acquirers. For Old Second, its geographic focus in the competitive Chicago suburbs means it must excel at relationship banking to defend its turf while seeking opportunistic M&A to build scale and enhance shareholder value over the next 3-5 years.
Commercial lending, particularly Commercial Real Estate (CRE), is Old Second's largest product line, accounting for the bulk of its interest income. Currently, usage is high, with commercial loans representing over 75% of its portfolio. However, consumption is constrained by several factors: higher interest rates make new development projects less financially viable, economic uncertainty tempers business expansion plans, and intense competition from other banks for the most creditworthy borrowers limits pricing power. Over the next 3-5 years, growth in this segment is expected to be selective. The non-owner-occupied CRE portion, especially office and some retail properties, may see a decrease in demand due to post-pandemic shifts in work and shopping habits. Growth will likely shift towards industrial properties, multi-family housing, and owner-occupied real estate. A primary catalyst for growth would be a stabilization of interest rates and a clear recovery in the regional economy. The market for commercial loans in the Chicago metropolitan area is vast, estimated to be well over $100 billion, but OSBC's share is small. The bank's growth will depend more on taking market share than on overall market expansion. Customers choose between OSBC and competitors like Wintrust Financial or Byline Bancorp based on relationships, speed of execution, and loan structure. OSBC can outperform when its local knowledge and relationship-based approach win over a local business owner, but it is likely to lose share to larger players like Wintrust on larger deals or to those who can offer more competitive pricing due to a lower cost of funds. A key future risk is a downturn in the local CRE market, which is a high probability. This would directly impact consumption by causing a freeze in new lending, higher credit losses, and potentially force the bank to take write-downs, directly hitting its earnings and capital.
Wealth management stands out as Old Second's most promising growth engine. This division currently provides a stable and high-margin source of fee income. Its growth is primarily limited by the geographic reach of the bank and the intense competition from a fragmented field of independent Registered Investment Advisors (RIAs), brokerage firms, and the private banking arms of national giants. Over the next 3-5 years, consumption of wealth management services is set to increase significantly. The primary driver is demographics, as the baby boomer generation continues to retire and requires wealth transfer and retirement income planning. Old Second is well-positioned to capture this by cross-selling wealth services to its existing affluent banking customers. The national wealth management market is a multi-trillion dollar industry, and even capturing a small additional share within its existing footprint can move the needle for OSBC. We can estimate a target for Assets Under Management (AUM) growth in the 5-8% annual range. Customers in this space choose advisors based on trust, personal connection, and perceived expertise. OSBC's century-long history and local brand give it an edge in building that trust, especially with clients who prefer an integrated relationship with their bank. It will outperform when it successfully leverages its banking relationships. However, it may lose clients seeking more sophisticated alternative investment products or a globally recognized brand, who might gravitate towards a larger firm like Morgan Stanley. The number of smaller advisory firms is expected to decrease due to consolidation, driven by rising technology and compliance costs. A key risk for OSBC is a severe equity market downturn (high probability), which would reduce AUM-based fees even if clients are retained. Another is the departure of key wealth advisors who could take a substantial book of business with them (medium probability).
Deposit services form the funding base for the bank's lending operations. Currently, the environment is defined by intense competition and a significant mix shift. Customers are actively moving funds from noninterest-bearing accounts to higher-yielding products like certificates of deposit (CDs) and money market accounts. This is a major constraint, as it directly increases the bank's cost of funds. As of early 2024, Old Second's noninterest-bearing deposits fell to ~28% of total deposits, and this proportion will likely continue to shrink over the next 1-2 years. In the coming 3-5 years, the trend of customers demanding higher returns on their cash is expected to persist. The portion of low-cost transaction accounts will likely stabilize at a lower level, while the bank will have to compete on price for savings and time deposits. Growth in deposits will likely be slow, perhaps 1-3% annually, and will come from deepening relationships with commercial clients through treasury management services and offering competitive digital tools for consumers. Customers choose their deposit institution based on a combination of interest rates, fees, digital convenience, and physical branch access. Old Second is losing on rate-sensitive retail savings to online-only banks like Ally but can win commercial operating accounts where relationships and specialized services matter more. The biggest risk is continued deposit cost pressure (high probability), which will squeeze the bank's net interest margin and profitability. A 50 basis point increase in the cost of deposits could reduce net interest income by over 10% if not offset by higher asset yields.
Looking ahead, Old Second's future growth trajectory will be heavily influenced by its M&A strategy. Having successfully integrated the transformative acquisition of West Suburban Bancorp in 2021, which nearly doubled its asset size, management has a proven playbook. The Chicago banking market remains fragmented, presenting numerous potential targets for consolidation. An accretive acquisition could provide a step-change in earnings per share, expand the bank's geographic reach within the Chicago suburbs, and allow it to spread its technology and overhead costs over a larger base. Without M&A, the bank's growth will be confined to low-single-digit organic loan growth, which is unlikely to excite investors. Therefore, the bank's ability to identify, execute, and integrate another strategic acquisition will be the single most important catalyst for shareholder value creation over the next five years. Furthermore, continued investment in digital capabilities is not optional but essential to defend its existing customer base and attract the next generation of clients. Failure to keep pace on the technology front would lead to a slow erosion of its franchise.
An analysis of Old Second Bancorp, Inc. (OSBC) suggests the stock is currently trading within a range that can be considered fair value, though not without risks. A triangulated fair value estimate places the stock's value between $17.00 and $20.00, with a midpoint of $18.50. With the current price trading almost exactly at this midpoint, there appears to be limited immediate upside, classifying the stock as Fairly Valued and making it a candidate for a watchlist.
The primary valuation method for a bank involves comparing its multiples to peers. OSBC’s trailing P/E ratio of 12.56x is in line with the regional bank industry average, but its forward P/E ratio of 8.78x is more compelling, indicating market expectations for strong earnings growth. For banks, the Price-to-Tangible Book Value (P/TBV) is a crucial metric. OSBC’s P/TBV stands at 1.37x, which is favorable compared to the broader regional bank sector where averages can be higher. Applying a peer-average P/TBV multiple of 1.4x to OSBC’s tangible book value suggests a fair value of approximately $18.91.
From a cash-flow perspective, OSBC offers a dividend yield of 1.51%, which is lower than many regional banks. However, its dividend is very safe, with a low payout ratio of 16.92% and strong recent growth of 19.05%, signaling significant room for future increases. A simple Gordon Growth Model, which values a company based on its future dividends, estimates the stock's value around $18.38. This cash flow-based valuation reinforces the idea that the stock is currently trading near its intrinsic value.
Combining the multiples and yield-based approaches provides a consistent picture. The multiples approach suggests a value near $19, while the dividend-based model points to a value around $18.40. Weighting the asset-based P/TBV multiple most heavily, as is standard for bank valuation, a fair value range of $17.00 to $20.00 seems appropriate. The current price falls squarely within this range, supporting the conclusion that Old Second Bancorp is fairly valued at present.
Bill Ackman's investment thesis for the banking sector centers on simple, high-quality franchises with dominant market positions and superior profitability, or clear turnaround situations he can influence. Old Second Bancorp would not appeal to Ackman as it fits neither category; it is a small, undifferentiated community bank with average performance metrics, including a Return on Average Assets (ROAA) of around 1.1% and an efficiency ratio above 60%, which lag behind top-tier peers. The key risk is its lack of a durable competitive moat in a market that increasingly favors scale and efficiency, making it difficult to generate the high returns on capital that Ackman seeks. OSBC's management uses cash for standard loan growth and dividends, but its returns on that reinvested capital are unexceptional, and its dividend yield is modest compared to some peers, indicating a capital allocation strategy that creates little standout value for shareholders. Therefore, in 2025, Ackman would decisively avoid the stock. If forced to select leaders in the space, he would prefer Wintrust Financial (WTFC) for its scale and brand dominance, Lakeland Financial (LKFN) for its best-in-class profitability, and Byline Bancorp (BY) for its unique SBA lending moat. A change in his view would require a major catalyst, such as an acquisition by a superior operator, which could unlock value through operational improvements.
Warren Buffett's investment thesis for banks focuses on simple, understandable businesses with durable competitive advantages, often seen through low-cost deposits, consistent high returns on assets, and trustworthy management. Old Second Bancorp (OSBC) would be seen as an understandable community bank, but it would not meet his high bar for quality. Its lack of a dominant moat in the competitive Chicago market, coupled with merely average profitability (Return on Average Assets of ~1.1%) and efficiency (efficiency ratio above 60%), places it far behind best-in-class peers. Management's capital allocation focuses on reinvesting for growth and paying a modest dividend (yield ~2%), a standard approach that is less attractive when returns are not top-tier. Given its geographic concentration in Illinois and lack of scale, Buffett would view it as a fair company at a fair price, not the wonderful company he seeks, and would therefore avoid the stock. If forced to invest in the sector, he would prefer dominant, higher-return institutions like Wintrust Financial (WTFC) for its scale, Lakeland Financial (LKFN) for its ~1.4% ROAA, or Mercantile Bank (MBWM) for its sub-55% efficiency ratio. The key takeaway for retail investors is that OSBC is a solid but unremarkable bank that lacks the exceptional economic engine of a true Buffett-style investment. Buffett would likely only become interested if the price fell to a significant discount to its tangible book value, offering an undeniable margin of safety.
Charlie Munger would view Old Second Bancorp as a standard, undifferentiated community bank that fails to meet his high bar for exceptionalism. Munger’s approach to banking prioritizes simple, disciplined institutions with durable, low-cost deposit franchises and a culture of risk avoidance, leading to superior, long-term returns on equity. OSBC, with a respectable but average Return on Average Assets (ROAA) of around 1.1% and an efficiency ratio often above 60%, would be seen as a competent but mediocre operator. For context, ROAA shows how well a bank uses its assets to make money, and top-tier banks exceed 1.3%; the efficiency ratio shows how much it costs to generate a dollar of revenue, where lower is better, and elite banks are near 50%. Munger would contrast OSBC with higher-quality peers that demonstrate superior operational skill and stronger competitive moats, making them far more attractive long-term investments even at higher valuations. If forced to choose the best banks in this space, Munger would likely favor Lakeland Financial (LKFN) for its consistent top-tier profitability (ROAA >1.4%), Mercantile Bank (MBWM) for its incredible operational efficiency (ratio <55%), and perhaps Byline Bancorp (BY) for its unique and defensible moat in high-margin SBA lending. For retail investors, the takeaway is that while OSBC is a solid bank, Munger’s philosophy teaches that it's better to pay a fair price for a wonderful business than a low price for a fair one; OSBC falls into the latter category. Munger's decision might change if OSBC demonstrated a clear, sustained improvement in its efficiency and profitability metrics, pushing its returns into the top quartile of its peers, or if a market panic offered it at a deep discount to its tangible book value.
Old Second Bancorp, Inc. operates as a classic community-focused bank in the highly competitive Chicagoland area. Its strategy revolves around building deep, long-term relationships with small-to-medium-sized businesses and local individuals, a model that fosters loyalty and provides a stable deposit base. The bank primarily earns money from the spread between the interest it receives on loans and the interest it pays on deposits. This traditional approach means its performance is heavily influenced by local economic conditions, the interest rate environment, and its ability to manage credit risk within its loan portfolio. Compared to the broader banking industry, OSBC is a small player, which presents both opportunities and challenges.
The company's main competitive advantage is its entrenched position in its local communities. Having operated for over 150 years, it possesses significant brand recognition and a granular understanding of its markets, allowing it to make credit decisions that larger, more centralized banks might avoid. This community-centric model results in strong asset quality, as evidenced by a consistently low ratio of non-performing loans. However, this focus also limits its geographic diversification, making it more vulnerable to economic downturns in its specific Illinois markets than competitors with a wider footprint.
A key challenge for Old Second Bancorp is its scale. With approximately $6.2 billion in assets, it is significantly smaller than many regional competitors. This smaller size can result in a higher efficiency ratio, meaning it costs more to generate a dollar of revenue. For instance, while larger peers might operate with efficiency ratios in the low 50s, OSBC's is often higher, pressuring its profitability. Furthermore, smaller banks have less capacity to invest in the cutting-edge digital technology and marketing that customers increasingly demand, potentially putting them at a long-term disadvantage against both large national banks and nimble fintech startups.
Ultimately, OSBC is positioned as a steady, traditional banking institution. It doesn't typically exhibit the high growth of banks in faster-growing markets or the premium profitability of larger, more efficient operations. Instead, it offers a relatively conservative risk profile and a consistent, if modest, return. Its competitive standing hinges on its ability to leverage its local market knowledge to maintain loan quality and customer relationships, while carefully managing expenses to compete against a wide array of larger and more technologically advanced financial institutions.
Wintrust Financial Corporation (WTFC) is a much larger and more diversified financial holding company also headquartered in the Chicago area, making it a direct and formidable competitor to Old Second Bancorp. With over $50 billion in assets, WTFC dwarfs OSBC in scale, allowing it to offer a broader range of services, including commercial banking, wealth management, and specialty financing like insurance premium financing. This size and diversification give WTFC significant advantages in terms of operational efficiency, brand recognition, and lending capacity. While both banks compete for commercial and retail customers in the same geographic market, they operate on different levels, with OSBC focusing on a more traditional, smaller-scale community banking model and WTFC acting as a super-regional powerhouse.
In terms of Business & Moat, WTFC has a clear advantage. Brand: WTFC's brand is significantly stronger across the Chicago metropolitan area, supported by a larger marketing budget and high-profile sponsorships, leading to a much higher deposit market share of over 4.5% compared to OSBC's sub-1% share. Switching Costs: Both benefit from high switching costs typical of banking, but WTFC enhances this by bundling services like wealth management and treasury services for its commercial clients. Scale: WTFC's asset base of over $50 billion versus OSBC's $6.2 billion provides massive economies of scale, leading to better pricing from vendors and a lower cost of funds. Network Effects: WTFC's larger network of branches and ATMs (~175 locations vs. OSBC's ~50) creates a modest network effect for retail customers. Regulatory Barriers: Both face high regulatory hurdles, which is a draw. Winner: Wintrust Financial Corporation wins decisively due to its overwhelming scale and stronger brand recognition in their shared core market.
From a Financial Statement perspective, WTFC demonstrates superior performance. Revenue Growth: WTFC has consistently shown stronger revenue growth, driven by both organic loan growth and strategic acquisitions, with a 5-year average revenue growth rate around 8%, while OSBC's has been closer to 5%. Margins/Profitability: WTFC consistently posts a better efficiency ratio (cost to generate revenue), often in the mid-50% range, compared to OSBC's, which is typically above 60%. This efficiency drives stronger profitability, with WTFC's Return on Average Assets (ROAA) hovering around 1.3%, superior to OSBC's 1.1%. A higher ROAA means a company is better at converting its assets into profit. Balance Sheet: Both maintain solid capital ratios, but WTFC's larger, more diversified loan book is arguably less risky than OSBC's more concentrated portfolio. Dividends: Both offer dividends, but WTFC has a more consistent history of dividend growth. Winner: Wintrust Financial Corporation is the clear winner due to its superior profitability, efficiency, and growth.
Looking at Past Performance, WTFC has delivered stronger returns for shareholders. Growth: Over the past five years, WTFC has compounded earnings per share (EPS) at a faster rate than OSBC, reflecting its successful acquisition strategy and broader service offering. Margin Trend: WTFC has better managed its Net Interest Margin (NIM) through various rate cycles due to its sophisticated treasury management and diverse funding sources. TSR: Consequently, WTFC's Total Shareholder Return (TSR) over the last 3- and 5-year periods has outpaced OSBC's. Risk: While both are well-managed, WTFC's larger size and diversification provide a better risk profile, which is reflected in its higher credit ratings from agencies. Winner: Wintrust Financial Corporation wins on all counts: growth, margin management, shareholder returns, and risk profile.
For Future Growth, WTFC again holds the edge. Revenue Opportunities: WTFC's specialty finance businesses, such as insurance premium financing and commercial equipment leasing, provide growth avenues that are independent of the local Chicago economy, a diversifier OSBC lacks. Cost Efficiency: WTFC's ongoing investments in technology and process automation should allow it to continue improving its efficiency advantage. Market Demand: While both are tied to the Midwest economy, WTFC has a greater ability to acquire smaller banks to expand its footprint and enter new markets. Consensus estimates for WTFC's forward earnings growth are generally higher than for OSBC. Winner: Wintrust Financial Corporation has a more robust and diversified path to future growth.
In terms of Fair Value, OSBC often trades at a discount, which may attract value-oriented investors. Valuation: OSBC typically trades at a lower Price-to-Tangible Book Value (P/TBV) multiple, often around 1.2x, compared to WTFC's premium multiple of 1.6x or higher. P/TBV is a key metric for banks, comparing the stock price to the hard assets of the company. Justification: This valuation gap is justified by WTFC's superior financial performance; investors are willing to pay more for its higher profitability (Return on Tangible Common Equity often >15% vs. OSBC's ~12-14%) and more reliable growth. Dividend Yield: The dividend yields are often comparable, but WTFC's lower payout ratio suggests its dividend is safer and has more room to grow. Winner: Old Second Bancorp is the better value on a pure metrics basis, but WTFC's premium is arguably warranted by its higher quality.
Winner: Wintrust Financial Corporation over Old Second Bancorp, Inc. WTFC is the clear winner due to its superior scale, profitability, and diversification. Its key strengths are a dominant market position in Chicago, a highly efficient operation (efficiency ratio ~55%), and multiple revenue streams beyond traditional banking, which drive a robust ROAA of ~1.3%. OSBC's primary weakness is its lack of scale, which results in lower efficiency and profitability compared to WTFC. While OSBC is a solid community bank with good credit quality, its primary risk is its concentration in the Illinois economy and its inability to compete with the marketing power and product breadth of a rival like WTFC. The verdict is supported by WTFC's consistently higher returns on equity and stronger long-term shareholder returns.
First Busey Corporation (BUSE) is a regional bank holding company with a significant presence in Illinois, Missouri, and Florida, making it a relevant peer for Old Second Bancorp. With over $12 billion in assets, BUSE is roughly twice the size of OSBC, providing it with greater scale and geographic diversification. Both companies operate a community-focused banking model centered on commercial and retail lending, but BUSE's operations span multiple states, offering it protection from a downturn in a single local economy. This comparison highlights the strategic differences between a purely local player (OSBC) and a multi-state regional bank (BUSE).
Analyzing their Business & Moat, BUSE has a slight edge. Brand: Both banks have strong local brands in their core markets, but BUSE's brand extends across a wider geography. BUSE's deposit share in its key Illinois markets is comparable to OSBC's in its respective areas. Switching Costs: High for both, as is typical for core banking relationships. Scale: BUSE's $12 billion asset base gives it an advantage over OSBC's $6.2 billion, enabling greater lending limits and better operational leverage. Network Effects: BUSE's larger, multi-state footprint (~60 branches vs. OSBC's ~50) provides a slightly better network for customers who travel or do business across the Midwest. Regulatory Barriers: A draw, as both operate under the same stringent banking regulations. Winner: First Busey Corporation, primarily due to its superior scale and valuable geographic diversification.
In a Financial Statement Analysis, the two companies are closely matched, with BUSE having a small advantage. Revenue Growth: Both companies have relied on a mix of organic growth and acquisitions, with similar low-single-digit revenue growth rates in recent years. Margins/Profitability: Their key profitability metrics are often very close. Both typically report a Net Interest Margin (NIM) in the 3.0% - 3.3% range and a Return on Average Assets (ROAA) around 1.0% - 1.1%. BUSE, however, often achieves a slightly better efficiency ratio (~58-60% vs OSBC's ~60-62%) due to its larger scale. Balance Sheet: Both are well-capitalized with solid tangible common equity ratios above 8%. Asset quality is also strong at both institutions, with non-performing asset ratios typically below 0.60%. Dividends: BUSE generally offers a higher dividend yield. Winner: First Busey Corporation, by a narrow margin, due to slightly better efficiency and a more attractive dividend profile.
Their Past Performance shows a very competitive history. Growth: Over the last five years, both banks have used acquisitions to fuel growth, resulting in somewhat lumpy but comparable EPS growth trajectories. Neither has been a high-growth standout. Margin Trend: Both have seen their Net Interest Margins compressed during periods of low interest rates and expand during hiking cycles, with no clear long-term winner in margin management. TSR: Total Shareholder Return for both stocks has been cyclical and often tracks the broader regional bank index, with performance leadership trading back and forth over various 1-, 3-, and 5-year periods. Risk: Their risk profiles are similar, characterized by conservative underwriting and low loan losses. Winner: This category is a draw, as neither has established a sustained performance advantage over the other.
The Future Growth outlook is marginally better for BUSE. Revenue Opportunities: BUSE's presence in Florida provides exposure to a faster-growing demographic and economic environment than OSBC's exclusive focus on Illinois. This is a significant long-term advantage. Cost Efficiency: Both banks are focused on managing costs, but BUSE's larger scale gives it more opportunities to leverage technology investments across a broader asset base. Market Demand: While the Midwest offers stable, slow-growth opportunities, BUSE's ability to allocate capital to its Florida markets gives it a distinct edge. Winner: First Busey Corporation, as its geographic diversification, particularly its Florida footprint, offers a more compelling long-term growth story.
From a Fair Value standpoint, both banks often trade at similar valuations. Valuation: Both OSBC and BUSE typically trade at a Price-to-Tangible Book Value (P/TBV) multiple in the 1.1x to 1.4x range and a Price-to-Earnings (P/E) ratio of around 9x to 11x. Any valuation difference between them is usually minor. Quality vs. Price: Given their similar profitability and risk profiles, neither typically commands a significant premium over the other. The choice often comes down to an investor's preference for BUSE's higher dividend yield and geographic diversification versus OSBC's pure-play focus on the Chicago suburbs. Dividend Yield: BUSE consistently offers a more attractive dividend yield, often above 4%, compared to OSBC's yield which is typically closer to 2%. Winner: First Busey Corporation is arguably the better value, primarily because you are not paying a premium for a more diversified business model and a significantly higher dividend yield.
Winner: First Busey Corporation over Old Second Bancorp, Inc. BUSE emerges as the winner due to its larger scale, valuable geographic diversification, and more generous dividend yield, all without commanding a significant valuation premium. Its key strengths are its solid footing in the stable Midwest combined with a growth engine in Florida, and a strong dividend yield often exceeding 4%. OSBC's primary weakness in this comparison is its complete reliance on the Illinois economy, which presents a concentration risk. While OSBC is a well-run bank with a strong local franchise, BUSE offers a similar quality profile but with a better risk-reward proposition for investors seeking income and modest growth. The verdict is supported by BUSE's ability to offer a similar profitability profile while providing diversification that OSBC lacks.
Byline Bancorp, Inc. (BY) is another Chicago-based commercial bank and a direct competitor to Old Second Bancorp. With assets of approximately $9 billion, Byline is larger than OSBC and has carved out a niche for itself in serving small and medium-sized businesses in the Chicago area. It is also one of the top Small Business Administration (SBA) lenders in the country, which provides a specialized, high-margin revenue stream. This focus on government-guaranteed lending differentiates its business model from OSBC's more traditional commercial and consumer lending approach, making for an interesting head-to-head comparison of strategy within the same geographic market.
In the Business & Moat assessment, Byline Bancorp holds a distinct advantage. Brand: Both have recognizable brands in Chicago, but Byline has cultivated a stronger reputation specifically among small businesses. Switching Costs: High for both, but Byline's expertise in the complexities of SBA lending creates a stickier relationship with those specific clients. Scale: Byline's $9 billion asset base provides a scale advantage over OSBC's $6.2 billion. Network Effects: Not a significant factor for either. Other Moats: Byline's greatest moat is its specialized expertise and high-ranking status as a national SBA lender (a top 5 SBA 7(a) lender nationally). This is a durable competitive advantage that is difficult to replicate and provides a fee-income stream that OSBC lacks. Regulatory Barriers: A draw for both. Winner: Byline Bancorp, Inc., due to its larger scale and, most importantly, its powerful, specialized moat in government-guaranteed lending.
Reviewing their Financial Statements, Byline often demonstrates stronger profitability. Revenue Growth: Byline's revenue growth has historically been more robust, aided by gains on the sale of the guaranteed portion of its SBA loans. This can, however, make revenue more volatile than OSBC's interest-income-driven model. Margins/Profitability: Byline typically generates a higher Return on Average Assets (ROAA), often in the 1.2% to 1.4% range, compared to OSBC's 1.1%. This is a direct result of the high margins on its specialized lending activities. Its efficiency ratio is also generally better than OSBC's. Balance Sheet: Both banks maintain strong capital levels. However, Byline's loan book has a unique composition due to the government-guaranteed portion of its SBA loans, which carries zero risk weighting, arguably making its balance sheet more capital-efficient. Winner: Byline Bancorp, Inc. is the winner due to its superior profitability metrics, driven by its high-margin niche business.
An analysis of Past Performance reveals Byline's more dynamic, though potentially more volatile, results. Growth: Byline has achieved a higher EPS CAGR over the last five years, reflecting the success of its SBA lending platform. Margin Trend: Byline's Net Interest Margin (NIM) is comparable to OSBC's, but its noninterest income is a much larger percentage of total revenue, providing a different performance driver. TSR: Byline's Total Shareholder Return has generally outperformed OSBC's over the last 3- and 5-year periods, as investors have rewarded its higher profitability. Risk: The risk profiles differ; OSBC's is a traditional credit risk model, while Byline's includes exposure to the volumes and premiums in the SBA market, which can be cyclical. However, its underwriting has been strong. Winner: Byline Bancorp, Inc. wins based on its superior historical growth and shareholder returns.
Looking at Future Growth prospects, Byline appears to have more distinct drivers. Revenue Opportunities: Byline's national SBA platform is a key growth engine that is not dependent on the Chicago economy. It can continue to grow this business line regardless of local conditions. OSBC's growth, in contrast, is tethered to loan demand in its specific Illinois markets. Cost Efficiency: Both are focused on managing expenses, but Byline's larger scale and specialized platforms may offer better long-term efficiency potential. Market Demand: Demand for SBA loans is counter-cyclical, potentially providing Byline with a buffer during economic downturns that OSBC lacks. Winner: Byline Bancorp, Inc. has a clearer and more diversified path to future growth thanks to its national lending platform.
In terms of Fair Value, Byline often trades at a premium, which seems justified. Valuation: Byline typically trades at a higher P/TBV multiple (e.g., 1.4x-1.6x) compared to OSBC (1.2x-1.4x). Its P/E ratio is often similar or slightly higher. Quality vs. Price: The premium valuation for Byline is justified by its superior profitability (higher ROAA and ROATCE) and unique growth engine in SBA lending. Investors are paying for a higher-quality and differentiated business model. Dividend Yield: The dividend yields are generally low for both, as they prioritize retaining capital for growth. Winner: Old Second Bancorp could be considered the better value for a price-sensitive investor, but Byline Bancorp represents better value for an investor willing to pay for higher quality and growth (a GARP-style investment).
Winner: Byline Bancorp, Inc. over Old Second Bancorp, Inc. Byline is the definitive winner due to its specialized and profitable business moat, superior financial metrics, and more robust growth outlook. Its key strength is its national SBA lending platform, which generates high-margin fee income and diversifies its revenue away from the local Chicago economy, driving a strong ROAA of over 1.2%. OSBC's weakness in this matchup is its traditional, undifferentiated business model that is entirely dependent on its local market. While OSBC is a stable bank, Byline's strategy has proven to deliver superior profitability and shareholder returns. The verdict is supported by Byline's differentiated competitive advantage, which translates directly into better financial results.
Mercantile Bank Corporation (MBWM) is a bank holding company headquartered in Michigan, making it a good regional peer for Old Second Bancorp, representing a similar Midwestern economic exposure but in a different state. With approximately $5 billion in assets, MBWM is slightly smaller than OSBC but operates a very similar business model focused on commercial and retail banking. Mercantile is known for its strong commercial real estate lending and consistent, disciplined operational performance. This comparison provides insight into how OSBC stacks up against a similarly sized, well-run community bank in a neighboring state.
Regarding Business & Moat, the two banks are very evenly matched. Brand: Both possess strong, long-standing brands within their respective core markets (Western/Central Michigan for MBWM, suburban Chicago for OSBC). Switching Costs: A draw, as both benefit from the inherent stickiness of customer banking relationships. Scale: The banks are very close in size (~$5B for MBWM vs. ~$6B for OSBC), meaning neither has a meaningful scale advantage over the other. Network Effects: Limited for both, with branch networks (~45 for MBWM, ~50 for OSBC) that are critical locally but don't create broad network effects. Regulatory Barriers: A draw. Winner: This category is a draw. Both are classic community banks whose moat is derived from their deep local market knowledge and customer relationships rather than overwhelming scale or unique products.
Their Financial Statements reveal that Mercantile Bank is a more efficient and profitable operator. Revenue Growth: Both have posted similar low-to-mid-single-digit revenue growth in recent years, driven by steady loan portfolio expansion. Margins/Profitability: This is where MBWM stands out. It consistently generates a much better efficiency ratio, often below 55%, while OSBC's is typically above 60%. This cost control translates directly to a superior bottom line, with MBWM's Return on Average Assets (ROAA) frequently exceeding 1.4%, significantly higher than OSBC's 1.1%. Balance Sheet: Both are well-capitalized with strong asset quality. MBWM has a higher concentration in commercial real estate, which could be a risk, but it has managed this portfolio exceptionally well historically. Winner: Mercantile Bank Corporation is the decisive winner due to its significantly higher profitability, driven by excellent operational efficiency.
Looking at Past Performance, Mercantile has been the more consistent performer. Growth: While top-line growth has been similar, MBWM's superior efficiency has allowed it to grow its earnings per share (EPS) at a more consistent and slightly faster rate than OSBC over the last five years. Margin Trend: MBWM has shown more skill in protecting its Net Interest Margin (NIM) and, more importantly, has steadily improved its efficiency ratio over time. TSR: Reflecting its stronger profitability, MBWM's Total Shareholder Return has generally been superior to OSBC's over 3- and 5-year timelines. Risk: Both have excellent credit risk management track records. Winner: Mercantile Bank Corporation wins due to its stronger and more consistent profitability and shareholder returns.
For Future Growth, the outlook is comparable for both banks. Revenue Opportunities: Both operate in mature, slow-growth Midwestern economies. Growth for both will likely come from gaining market share and deepening customer relationships rather than a booming economic backdrop. Neither has a clear advantage in market-driven growth. Cost Efficiency: MBWM already operates at a high level of efficiency, so further gains may be incremental. OSBC has more room for improvement, which could be a source of earnings growth if it can successfully execute cost-saving initiatives. Market Demand: Loan demand is expected to be modest in both Michigan and Illinois. Winner: This category is a draw. Neither bank has a standout growth catalyst, with future success depending on execution.
From a Fair Value perspective, Mercantile often commands a premium valuation for its higher quality. Valuation: MBWM tends to trade at a higher P/TBV multiple (1.4x-1.6x) and P/E ratio (9x-11x) compared to OSBC (P/TBV of 1.2x-1.4x, P/E of 9x-10x). Quality vs. Price: The premium for MBWM is justified by its best-in-class profitability. Investors are willing to pay more for its impressive ROAA (>1.4%) and efficiency ratio (<55%). It is a clear case of paying a fair price for a high-quality company. Dividend Yield: Both offer comparable dividend yields, typically in the 2-3% range. Winner: Old Second Bancorp is cheaper on a relative basis, but Mercantile Bank Corporation likely represents better value when its superior profitability is factored in. It is a classic quality-at-a-fair-price stock.
Winner: Mercantile Bank Corporation over Old Second Bancorp, Inc. Mercantile Bank is the winner because it is a demonstrably more profitable and efficient bank operating a very similar business model. Its key strength is its exceptional operational management, which produces a top-tier efficiency ratio of under 55% and a powerful ROAA that often exceeds 1.4%. OSBC's main weakness in this comparison is its relatively inefficient operations, which prevent it from matching MBWM's profitability despite its larger size. While both are solid, well-managed community banks, MBWM's superior financial results have led to better long-term returns for shareholders. The verdict is supported by the significant and persistent gap in profitability and efficiency between the two banks.
Lakeland Financial Corporation (LKFN) is the holding company for Lake City Bank, based in Indiana. With over $6.5 billion in assets, it is very similar in size to Old Second Bancorp and provides a strong comparison of operational execution between two Midwestern community banks. Lakeland Financial has a reputation for being a high-quality, conservative institution with a strong track record of organic growth and consistent profitability. Its focus is solely on the state of Indiana, making it a pure-play on that state's economy, just as OSBC is a pure-play on its northern Illinois markets.
In a Business & Moat analysis, Lakeland Financial has a slight edge due to market dominance. Brand: Lake City Bank is a dominant brand in its northern Indiana markets, often holding the #1 or #2 deposit market share in the counties it serves. OSBC has a solid brand but faces a much more fragmented and competitive banking landscape in the Chicago suburbs. Switching Costs: A draw, as both benefit from sticky customer deposits. Scale: The two banks are nearly identical in asset size (~$6.5B), so neither has a scale advantage. Network Effects: Not significant for either. Regulatory Barriers: A draw. Winner: Lakeland Financial Corporation, due to its more dominant competitive position within its chosen markets, which provides better pricing power and a more stable deposit base.
Financially, Lakeland Financial has historically been a superior performer. Revenue Growth: LKFN has a long history of delivering consistent high-single-digit organic loan growth, often outpacing OSBC's growth rate. Margins/Profitability: LKFN is a top performer in profitability. Its Return on Average Assets (ROAA) is consistently high, often 1.4% or more, and its efficiency ratio is excellent, typically in the low 50% range. This compares very favorably to OSBC's ROAA of ~1.1% and efficiency ratio of >60%. Balance Sheet: LKFN is known for its pristine asset quality and conservative underwriting, and it maintains very strong capital ratios. Dividends: LKFN has an exceptional track record of annual dividend increases. Winner: Lakeland Financial Corporation is the clear winner, showcasing best-in-class profitability, efficiency, and consistent organic growth.
Looking at Past Performance, Lakeland's history is one of steady excellence. Growth: LKFN has a multi-decade track record of positive earnings, compounding EPS at an impressive rate for a community bank through disciplined organic growth, not acquisitions. Margin Trend: It has demonstrated an ability to protect its margins better than most peers through various interest rate cycles. TSR: As a result of its premium performance, LKFN's Total Shareholder Return has significantly outperformed OSBC and the broader regional bank index over most long-term periods. Risk: LKFN is considered a lower-risk bank due to its conservative culture and consistent performance, often reflected in a premium valuation. Winner: Lakeland Financial Corporation wins decisively based on its stellar long-term track record of growth, profitability, and shareholder returns.
For Future Growth, Lakeland's outlook is based on continuing its proven strategy. Revenue Opportunities: LKFN's growth strategy is simple: continue to take market share in the growing commercial and industrial loan space within Indiana. Its strong reputation and commercial banking expertise are its key drivers. OSBC's growth is similarly tied to winning business in its local market. Cost Efficiency: LKFN is already highly efficient, so its focus is on maintaining that edge through technology and disciplined expense management. Market Demand: Indiana's economy is heavily tied to manufacturing and logistics, offering steady growth opportunities. Winner: Lakeland Financial Corporation, because its historical execution provides more confidence that it can achieve its future growth targets organically.
Regarding Fair Value, Lakeland Financial consistently trades at a significant premium, and for good reason. Valuation: LKFN almost always trades at one of the highest P/TBV multiples in the community bank sector, often above 2.0x, and a P/E ratio in the 12x-15x range. This is substantially higher than OSBC's valuation. Quality vs. Price: This is the definition of a premium valuation for a premium company. Investors have long been willing to pay up for LKFN's superior and consistent profitability (ROATCE often >18%), pristine balance sheet, and reliable growth. Dividend Yield: Its dividend yield is typically lower than OSBC's, as its higher stock price outweighs its strong dividend growth. Winner: Old Second Bancorp is the cheaper stock by a wide margin, but Lakeland Financial Corporation is widely considered one of the highest-quality community banks in the nation, making its premium justifiable for quality-focused investors.
Winner: Lakeland Financial Corporation over Old Second Bancorp, Inc. Lakeland is the decisive winner, representing a best-in-class example of a high-performing community bank. Its key strengths are its dominant market share in its Indiana footprint, consistently elite profitability metrics (ROAA >1.4%, efficiency ratio ~52%), and a long-term record of disciplined organic growth. OSBC's primary weakness in this comparison is its average profitability and efficiency, which simply cannot match LKFN's top-tier performance. While an investor must pay a significant valuation premium for LKFN, its historical performance suggests it is one of the few banks that has earned it. The verdict is supported by nearly every key performance metric, from profitability and efficiency to long-term shareholder returns.
Midland States Bancorp, Inc. (MSBI) is another Illinois-based community bank that serves as a relevant peer to Old Second Bancorp. With approximately $7.5 billion in assets, MSBI is slightly larger and has a more diversified business model that includes a sizable wealth management division. Its geographic footprint extends beyond Illinois into Missouri. The presence of a significant fee-generating wealth management business is a key strategic difference from OSBC's almost exclusive focus on traditional banking services. This comparison will highlight the benefits and drawbacks of a more diversified revenue stream.
Analyzing their Business & Moat, Midland States Bancorp has a modest advantage. Brand: Both have established brands in their respective Illinois markets. Switching Costs: High for both, but MSBI's wealth management arm adds another layer of stickiness for its high-net-worth clients, as integrated banking and wealth services are difficult to disentangle. Scale: MSBI's larger asset base ($7.5B vs. OSBC's $6.2B) provides a slight scale advantage. Other Moats: MSBI's wealth management business, with over $4 billion in assets under administration, provides a valuable, capital-light, fee-based revenue stream. This diversification is a key competitive advantage that OSBC lacks. Regulatory Barriers: A draw. Winner: Midland States Bancorp, Inc., due to its larger scale and, more importantly, its diversified business model which includes a significant wealth management operation.
From a Financial Statement perspective, the results are often comparable, with different drivers. Revenue Growth: MSBI's revenue can be more stable due to the recurring nature of its wealth management fees, which are less sensitive to interest rate fluctuations than OSBC's net interest income. Margins/Profitability: Both banks typically report similar ROAA (~1.0-1.1%) and efficiency ratios (~60-65%). While MSBI's wealth business helps the top line, it also comes with its own operating expenses. Neither bank has demonstrated a clear, sustained advantage in core profitability over the other. Balance Sheet: Both are well-capitalized with solid credit quality metrics. Winner: This category is a draw. MSBI's diversification has not translated into consistently superior profitability compared to OSBC's more focused model.
Their Past Performance shows similar, cyclical returns. Growth: Both companies have used M&A to supplement organic growth, leading to periods of expansion followed by consolidation. Their long-term EPS growth rates have been comparable. Margin Trend: Both have seen their Net Interest Margins fluctuate with interest rate cycles. MSBI's overall margin is supported by its fee income, which has provided a buffer when lending margins were compressed. TSR: Total Shareholder Return for both stocks has been similar over most 3- and 5-year periods, often tracking the performance of other small-cap Midwestern banks. Neither has been a breakout performer. Risk: MSBI's diversified model arguably carries a slightly lower risk profile due to its less reliance on net interest income. Winner: This category is a draw, as neither has delivered meaningfully better results or returns over the long term.
For Future Growth, MSBI's diversified model offers more levers to pull. Revenue Opportunities: MSBI can grow by expanding its wealth management business, either organically by gathering assets or through acquisitions of registered investment advisor (RIA) firms. This is a growth avenue entirely unavailable to OSBC. Growth in its traditional banking business faces the same slow-growth Midwest economic headwinds as OSBC. Cost Efficiency: Both banks are focused on improving efficiency, and both have room for improvement. Market Demand: The demand for wealth management services is a secular tailwind driven by an aging population, giving MSBI a growth driver independent of loan demand. Winner: Midland States Bancorp, Inc., as its wealth management division provides a distinct and attractive path for future growth.
In terms of Fair Value, the market typically values these two banks very similarly. Valuation: MSBI and OSBC tend to trade at nearly identical P/TBV (1.1x-1.3x) and P/E (9x-11x) multiples. The market does not seem to assign a significant premium for MSBI's diversified business model. Quality vs. Price: Given that their profitability metrics are often aligned, the similar valuations seem appropriate. Dividend Yield: MSBI often provides a more generous dividend yield, which can make it more attractive to income-focused investors. Winner: Midland States Bancorp, Inc. is arguably the better value, as an investor gets the benefit of a diversified business model and a higher dividend yield at essentially the same valuation as OSBC.
Winner: Midland States Bancorp, Inc. over Old Second Bancorp, Inc. MSBI wins this comparison by a narrow margin. The victory is based on its more diversified business model and better dividend yield, which are available at a valuation that is typically no more expensive than OSBC's. Its key strength is the combination of a traditional community bank with a substantial wealth management business, which provides a stable fee-income stream and an additional avenue for growth. OSBC's main weakness here is its singularity; its fate is tied almost entirely to the fortunes of traditional lending in one geographic area. While both banks have produced similar financial results in the past, MSBI's strategic diversification makes it a slightly less risky and more attractive long-term investment. The verdict is supported by the fact that MSBI offers more strategic options without a corresponding premium in its stock price.
Based on industry classification and performance score:
Old Second Bancorp operates a traditional community banking model focused on the competitive Chicago suburban market. Its primary strength lies in its established wealth management division, which provides stable, high-margin fee income and represents its most durable competitive advantage. However, the bank's moat is narrow overall, limited by intense competition and a significant concentration in commercial real estate loans, which carries elevated risk. The investor takeaway is mixed, as the bank's stable local franchise is offset by its lack of scale and exposure to a potentially volatile loan segment.
The bank's strong and stable wealth management business provides a high-quality source of fee income, diversifying its revenue away from interest rate-sensitive lending.
Noninterest income provides a crucial buffer when lending margins are squeezed. In the first quarter of 2024, Old Second's noninterest income represented 19.7% of its total revenue, a healthy contribution for a community bank. More importantly, the quality of this income is high. Wealth management fees, which are stable and recurring, contributed $4.5 million, or about 32% of the total noninterest income. This is a significant strength compared to peers that rely more heavily on volatile sources like mortgage banking income ($0.9 million for OSBC). This strong contribution from a high-margin, relationship-driven business like wealth management is a key differentiator and a sign of a more resilient business model.
Old Second demonstrates a healthy mix of consumer and business deposits with minimal reliance on volatile brokered funds, indicating a well-managed and diversified funding base.
A stable bank is not overly reliant on a single source of deposits. Old Second appears to have a balanced deposit composition, drawing from a mix of retail consumers, small businesses, and public funds from local municipalities. The bank does not rely heavily on brokered deposits, which are considered less stable, "hot money" that can leave quickly in search of higher rates. This diversified mix reduces concentration risk and makes the bank less vulnerable to sudden shifts in a particular customer segment. By cultivating a broad base of local depositors, OSBC ensures a more resilient funding profile capable of weathering different economic environments. This prudent management of its deposit sources is a clear strength.
The bank lacks a distinct lending niche and carries a heavy concentration in non-owner-occupied commercial real estate, which increases its risk profile.
While expertise in a specific lending area can create a competitive advantage, Old Second's loan portfolio appears more generalist and carries notable concentration. As of the end of 2023, non-owner-occupied commercial real estate (CRE) accounted for 38% of the total loan portfolio. This is a significant exposure to a single, economically sensitive asset class that is currently facing headwinds from higher interest rates and changing usage patterns (e.g., office space). While the bank also has a solid C&I and owner-occupied CRE book (~38% combined), the lack of a specialized, defensible niche and the heavy weighting toward investor CRE suggests a higher-risk strategy rather than a differentiated, moat-worthy franchise. This concentration makes the bank's earnings more vulnerable to a downturn in the commercial property market.
The bank maintains a decent but declining base of low-cost deposits, though its overall funding costs are rising in line with the industry, limiting its competitive edge.
A bank's strength often comes from a loyal, low-cost deposit base. As of the first quarter of 2024, Old Second's noninterest-bearing deposits—the cheapest funding source for a bank—stood at 28.3% of total deposits. While this provides a benefit, this percentage is roughly in line with the peer average and has been declining as customers seek higher yields. The bank's cost of total deposits was 2.64%, reflecting the broader industry trend of rising funding costs. Furthermore, with an estimated 33% of deposits being uninsured as of year-end 2023, there is a moderate risk of outflows if depositor confidence wanes. Because OSBC does not exhibit a significantly lower cost of funds or a stickier deposit base than its competitors, it doesn't possess a strong advantage in this area.
Old Second's branch network provides a solid local presence, but its efficiency in gathering deposits per branch is average for its peer group.
Old Second Bancorp operates a network of 58 branches primarily located in Chicago's western suburbs. With approximately $6.0 billion in total deposits, the bank has about $103 million in deposits per branch. This figure is broadly in line with the average for many community banks of its size but does not suggest a significant scale or efficiency advantage. A strong branch network in a specific geography can create a mini-moat by providing convenience for customers and acting as a hub for relationship-based banking. However, without superior deposit-gathering efficiency per location, the network is more of a necessary operational footprint than a distinct competitive strength. The lack of significant branch optimization or industry-leading metrics indicates an average, but not standout, physical presence.
Old Second Bancorp's recent financial health presents a mixed picture, heavily influenced by a likely acquisition. While net interest income grew a strong 36.6% year-over-year in the latest quarter, profitability was severely impacted by a massive $19.65 million provision for credit losses, causing net income to fall by 57%. The balance sheet has expanded significantly to nearly $7 billion in assets, but this growth comes with higher expenses and potential credit risks. For investors, the takeaway is mixed; the bank is growing, but the sharp increase in loan loss provisions and worsening efficiency raise significant concerns about near-term earnings quality and integration risk.
The bank maintains a solid capital position with a healthy tangible equity ratio and a reasonable loan-to-deposit ratio, though crucial data on regulatory capital and uninsured deposits is unavailable.
Old Second Bancorp appears to have a sufficient capital and liquidity foundation. The tangible common equity to total assets ratio was 10.18% as of Q3 2025, a strong level that provides a solid cushion to absorb potential losses. This is a key measure of a bank's ability to withstand financial stress without relying on intangible assets like goodwill. The loan-to-deposit ratio stood at 90.1%, which is within a healthy range, indicating the bank is not overly aggressive in its lending relative to its deposit funding base and has capacity for further growth.
However, a complete analysis is hampered by the absence of key regulatory metrics like the CET1 ratio and Tier 1 leverage ratio, which are standard measures of capital adequacy. Additionally, there is no information provided on the level of uninsured deposits, a critical liquidity risk factor for any bank. While the available metrics are positive, the lack of these essential data points prevents a full-throated endorsement. Based on the strength of the tangible equity and a conservative loan funding profile, the bank passes, but investors should seek more clarity on regulatory capital levels.
A massive and sudden increase in the provision for credit losses to nearly `$20 million` in the latest quarter raises serious concerns about deteriorating credit quality or risks within the loan portfolio.
The bank's credit quality is a major area of concern. In Q3 2025, Old Second Bancorp set aside $19.65 million as a provision for credit losses. This is a dramatic increase from just $2.5 million in the previous quarter and $12.75 million for the entire 2024 fiscal year. Such a large provision is a significant red flag, suggesting that management either anticipates future loan defaults or has identified emerging problems within its loan book, possibly related to its recent acquisition. This single expense item was the primary reason for the 57% drop in the company's net income for the quarter.
In response to this risk, the bank has increased its reserves. The allowance for credit losses as a percentage of gross loans rose to 1.42% from 1.08% in the prior quarter. While building reserves is a prudent step, the sheer size of the provision needed to get there is alarming. Without data on nonperforming loans or net charge-offs, it is difficult to know if this provision is proactive or reactive to existing problems. Regardless, the magnitude of the provision signals heightened credit risk and justifies a failing grade for this factor.
The bank's earnings are showing significant sensitivity to interest rates, as a sharp increase in interest expense outpaced the growth in interest income, leading to a recent drop in profitability.
Old Second Bancorp's sensitivity to interest rates is evident in its latest quarterly results. Total interest expense more than doubled from $11 million in Q2 2025 to $21.3 million in Q3 2025. This rapid increase in funding costs, particularly interest paid on deposits, squeezed the bank's profitability despite growth in total interest income. This suggests that the bank's liabilities, like deposits, are repricing faster than its assets, which is a common challenge in a rising rate environment.
Furthermore, the balance sheet shows an accumulated other comprehensive loss (listed as ComprehensiveIncomeAndOther) of -$32.3 million, which represents unrealized losses on its investment securities portfolio. This amounts to about 4.5% of the bank's tangible common equity ($711.5 million), indicating a manageable but noteworthy impact on its capital from interest rate movements. Given the sharp rise in funding costs and its direct negative impact on net income, the bank's current asset/liability management appears challenged. The lack of data on the mix of variable-rate loans makes a full assessment difficult, but the current earnings trend justifies a cautious view.
The bank achieved strong growth in its core net interest income, which rose over 36% year-over-year, demonstrating its ability to grow its primary revenue stream despite rising interest costs.
Old Second Bancorp's core earnings power from its lending and investing activities shows strength, even in a challenging interest rate environment. The bank's net interest income (NII) — the difference between what it earns on assets and pays on liabilities — grew 36.6% year-over-year to $82.8 million in Q3 2025. This robust growth, likely aided by its recent acquisition, indicates a positive expansion of its core revenue engine. This growth in NII is the fundamental driver of a bank's profitability, making this a significant positive point.
However, this growth is not without challenges. The bank's cost of funding is rising quickly, with total interest expense jumping from $11 million to $21.3 million in a single quarter. This indicates pressure on the net interest margin (NIM), which is the key profitability measure for a bank's spread. While the NIM percentage is not provided, the dollar growth of NII is strong enough to suggest the bank is successfully navigating the environment, at least on the top line. Because growing NII is the primary goal, and the bank is succeeding there, this factor earns a passing grade.
The bank's efficiency has significantly worsened, with the efficiency ratio climbing to over `66%` in the last quarter due to a sharp increase in operating expenses following a likely acquisition.
Old Second Bancorp's cost control has weakened considerably. The efficiency ratio, which measures noninterest expense as a percentage of revenue, jumped to a poor 66.2% in Q3 2025. This is a substantial deterioration from the much healthier 57.8% in Q2 2025 and 56.1% for fiscal year 2024. For community banks, an efficiency ratio below 60% is typically considered good, so the latest figure is well into inefficient territory. A higher ratio means the bank is spending more to generate each dollar of revenue, which directly hurts profitability.
The primary driver was a surge in total noninterest expense to $63.2 million from $43.4 million in the prior quarter. A large part of this was a jump in salaries and employee benefits, which is a common consequence of an acquisition. While some increase in costs is expected with expansion, the immediate impact on efficiency has been severe. The bank now faces the challenge of integrating its new operations and controlling costs to bring its efficiency back to a more profitable level. Until that improvement is demonstrated, the bank fails on this measure.
Old Second Bancorp's past performance is a story of transformative but inconsistent growth. The bank roughly doubled in size over the last five years, driven by a major acquisition in 2022, which significantly increased its earnings power. However, this growth was not smooth, leading to volatile earnings per share (EPS) and significant shareholder dilution. While profitability, measured by Return on Assets (ROA) of around 1.1%, has improved, it still lags more efficient peers. The investor takeaway is mixed; the bank has successfully scaled up, but its historical operational efficiency and earnings consistency are subpar compared to top-tier competitors.
The bank successfully doubled its loan and deposit base over the past five years, primarily through a large acquisition, while prudently managing its loan-to-deposit ratio.
Old Second Bancorp has demonstrated significant balance sheet growth over the analysis period. Gross loans increased from $2.0 billion in FY2020 to nearly $4.0 billion by FY2024, and total deposits grew from $2.5 billion to $4.8 billion. The vast majority of this growth occurred in FY2022 as a result of an acquisition, transforming OSBC into a larger community bank.
Despite this rapid, inorganic expansion, the bank appears to have managed its balance sheet prudently. The loan-to-deposit ratio—a key measure of a bank's liquidity—has fluctuated but remained in a reasonable range, moving from 80% in 2020 to 84% in 2024. This indicates the bank is not being overly aggressive in its lending relative to its core deposit funding. Successfully integrating a large acquisition and managing the combined balance sheet is a historical strength.
While the bank's net interest income has grown substantially with its larger balance sheet, its operational efficiency has been a persistent weakness, consistently lagging more profitable peers.
Over the past five years, Old Second's Net Interest Income (NII)—the profit from its core lending business—grew significantly from $91.8 million in FY2020 to $241.6 million in FY2024, driven by its acquisition. This shows the bank successfully scaled its primary revenue engine. Its Net Interest Margin (NIM), or the profitability of its loan book, is described in peer comparisons as being adequate and in line with competitors like First Busey.
The primary weakness in this area is the bank's efficiency ratio, a key measure of operational performance that shows expenses as a percentage of revenue. Peer analyses repeatedly highlight that OSBC's efficiency ratio is typically above 60%. This is noticeably weaker than high-performing competitors like Mercantile Bank (<55%) and Lakeland Financial (low 50%). A lower efficiency ratio is better, and OSBC's historically higher ratio means it costs them more to generate a dollar of revenue, which has been a consistent drag on its profitability compared to peers.
While earnings per share (EPS) are significantly higher than five years ago, the year-over-year growth path has been extremely volatile and inconsistent, undermining confidence in its predictability.
Old Second's EPS track record is a clear weakness from a consistency standpoint. Over the last five fiscal years, annual EPS growth has been a rollercoaster: -29.35% in 2021, followed by a +129.23% surge in 2022 after its acquisition, then +35.57% in 2023, and a dip of -7.43% in 2024. This pattern shows a lack of smooth, predictable growth that investors typically value in a bank's past performance.
The acquisition in 2022 clearly reset the bank's earnings power to a higher level, with EPS of $1.90 in 2024 being double the $0.94 from 2020. However, the erratic path to get there makes it difficult to assess management's ability to deliver steady organic growth. High-quality peers like Lakeland Financial are noted for delivering consistent growth, which stands in stark contrast to OSBC's lumpy and unpredictable earnings history.
The bank's provision for loan losses has remained at manageable levels over the past five years, suggesting a history of stable and disciplined credit underwriting without significant issues.
A review of Old Second's income statements shows a stable credit history. The provision for credit losses, which is money set aside to cover potential bad loans, has been managed well. As a percentage of total loans, provisions were approximately 0.52% in 2020 during the height of pandemic uncertainty and have since moderated, running between 0.17% and 0.41% in the last three years. These levels are not indicative of any systemic credit quality problems.
While specific data on net charge-offs (actual loan losses) and non-performing loans (loans at risk of default) is not provided, the provisioning trend is a good proxy for credit health. The levels are consistent with a bank that has maintained disciplined underwriting standards both before and after its major acquisition. Peer comparisons also note that OSBC's asset quality is solid and in line with competitors, supporting the conclusion of a stable credit performance.
OSBC has a strong record of growing its dividend from a low base with a safe payout ratio, but shareholder returns were significantly impacted by a massive, dilutive share issuance for an acquisition in 2022.
Over the past five years, Old Second Bancorp has aggressively grown its dividend per share from $0.04 in FY2020 to $0.21 in FY2024. This growth is supported by a very conservative dividend payout ratio, which has remained low, recently at just 11% of earnings. This indicates the dividend is well-covered by profits and has significant room to grow further. This is a clear positive for income-seeking investors.
However, the company's overall capital return history is marred by a major share issuance in FY2022, where the number of shares outstanding jumped by 47% to fund an acquisition. This action significantly diluted the ownership stake of existing shareholders. While acquisitions can create long-term value, such a large dilution is a direct cost to shareholders' per-share value. Since then, share repurchases have been minimal and not nearly enough to offset this event. The substantial dilution overshadows the positive dividend story.
Old Second Bancorp's future growth appears modest and is likely to be driven by disciplined acquisitions and the expansion of its strong wealth management business. The bank faces significant headwinds from intense competition in the Chicago market and pressure on its net interest margin as funding costs rise. Its heavy concentration in commercial real estate poses a risk in the current economic environment, potentially limiting aggressive loan growth. Compared to larger, more diversified competitors like Wintrust, OSBC's growth path is narrower. The overall investor takeaway is mixed, as the stability from its fee income is offset by limited organic growth prospects and sector-specific risks.
The outlook for loan growth is muted, constrained by a cautious approach to the risky commercial real estate market and intense competition for quality loans.
Management has not provided aggressive loan growth guidance, and the bank's significant concentration in commercial real estate (~38% in non-owner-occupied CRE) warrants a conservative stance. In the current economic climate of higher interest rates and uncertainty in the office sector, expanding this portfolio aggressively would be imprudent. Growth will likely be in the low single digits, focused on C&I and select, high-quality CRE projects. Without a clear catalyst or a strong pipeline in a less risky loan category, the outlook for meaningful organic loan growth over the next few years is limited.
With a proven history of successful, transformative M&A and solid capital levels, the bank is well-positioned to pursue future acquisitions as a primary driver of growth.
Old Second's 2021 acquisition of West Suburban Bancorp was a defining strategic move that demonstrated its capability to execute and integrate large-scale transactions. This history is the strongest indicator of its future growth strategy. The bank maintains healthy capital ratios, including a Common Equity Tier 1 (CET1) ratio comfortably above regulatory requirements, providing the financial flexibility to pursue another significant acquisition or continue opportunistic share buybacks. While no new deals have been announced, M&A remains the most plausible path for Old Second to achieve meaningful growth in earnings and shareholder value, making its capital position and M&A track record a distinct strength.
The bank maintains an average branch network efficiency and has not articulated a clear strategy for optimization or digital growth, suggesting a reactive rather than proactive approach to evolving customer behavior.
Old Second operates 58 branches, yielding approximately $103 million in deposits per branch. This metric is unremarkable and falls within the average range for community banks of its size, indicating no significant scale advantage or superior efficiency in its physical footprint. The company has not announced specific, measurable targets for branch consolidation, cost savings from optimization, or growth in digital user adoption. In an era where competitors are actively rationalizing their branch networks to fund technology investments, Old Second's apparent lack of a forward-looking optimization plan is a weakness that could lead to a higher cost structure relative to peers over time.
The bank's net interest margin (NIM) is facing significant pressure from rapidly rising deposit costs, which are expected to outpace the repricing of its assets.
Like most banks, Old Second is experiencing the negative effects of a higher interest rate environment on its funding costs. Its cost of total deposits rose to 2.64% in Q1 2024, and this trend is expected to continue as customers shift money into higher-yielding accounts. The bank's loan portfolio, with a substantial portion in fixed-rate commercial real estate, may not reprice upward quickly enough to offset this pressure. Without specific guidance indicating a stable or expanding NIM, the most likely scenario is continued margin compression over the next several quarters, which will act as a headwind to net interest income growth.
The bank's strong wealth management division provides a significant and stable source of high-quality fee income, offering a reliable growth driver that diversifies earnings away from lending.
Noninterest income represents a healthy ~20% of Old Second's total revenue, but its quality is more important than its quantity. The wealth management division is the crown jewel, contributing nearly a third ($4.5 million in Q1 2024) of this fee income. This revenue is recurring, high-margin, and less cyclical than income from lending or mortgage banking. This strong foundation in a sticky, relationship-driven business provides a clear and promising avenue for future growth as the bank cross-sells services to its existing client base. This focus on expanding a stable fee-generating business is a key positive for the bank's future earnings quality.
Based on its current valuation metrics, Old Second Bancorp, Inc. (OSBC) appears to be fairly valued. The stock trades at an attractive forward P/E ratio of 8.78x, suggesting anticipated earnings growth. Key valuation indicators such as its Price-to-Tangible Book Value (P/TBV) of 1.37x and a dividend yield of 1.51% are reasonable within the regional banking sector. However, significant recent share dilution presents a notable concern. The overall takeaway for investors is neutral; while the forward valuation is appealing, the dilution risk suggests a watchlist approach may be prudent.
The stock trades at a Price-to-Tangible Book Value of 1.37x, a key metric for banks, which is a reasonable valuation that appears justified by the company's historical profitability.
For banks, the Price-to-Tangible Book Value (P/TBV) ratio is often more important than the P/E ratio because it compares the stock price to the actual hard assets the bank holds. With a latest tangible book value per share of $13.51, OSBC’s P/TBV is 1.37x. This valuation is quite reasonable for the sector. While the highest-quality banks can trade at P/TBV ratios of 2.3x or more, a valuation below 1.5x is often seen as attractive, provided the bank is generating adequate returns. OSBC’s return on equity (ROE) was a solid 13.66% for the last full fiscal year. Although the ROE dropped to 4.98% in the most recent quarter due to a large provision for loan losses, its historical profitability supports the current P/TBV multiple. This factor earns a "Pass" as the valuation is sensible relative to its asset base.
The company’s historical Return on Equity of 13.66% adequately supports its Price-to-Book multiple of 1.13x, suggesting a proper alignment between profitability and valuation.
A bank's valuation, measured by its Price-to-Book (P/B) ratio, should be justified by its ability to generate profits from its equity, measured by Return on Equity (ROE). A higher ROE typically warrants a higher P/B multiple. OSBC's P/B ratio is 1.13x (based on a book value per share of $16.46). Its ROE for the 2024 fiscal year was strong at 13.66%. A bank that can generate a 13%+ return on its equity is generally considered to be creating value for shareholders, which supports a P/B ratio above 1.0x. The recent drop in quarterly ROE to 4.98% is a point of concern, but it was driven by a significant one-time loan loss provision. Assuming the bank's profitability reverts to its historical norm, the current P/B multiple is well-aligned with its earnings power. The current 10-Year Treasury yield of around 4.0% provides a baseline for risk-free returns, and OSBC's ROE comfortably exceeds this benchmark.
The stock's forward P/E ratio of 8.78x is attractive, sitting below its trailing P/E of 12.56x and industry averages, suggesting that the current price does not fully reflect expected near-term earnings growth.
The Price-to-Earnings (P/E) ratio is a key indicator of whether a stock is cheap or expensive relative to its earnings power. OSBC's trailing twelve-month (TTM) P/E ratio of 12.56x is reasonable, aligning with the industry average for regional banks which is around 11.7x to 13.5x. The more important metric here is the forward P/E ratio, which uses estimated future earnings. OSBC’s forward P/E is a much lower 8.78x. This significant drop from the trailing P/E implies that analysts expect the company's earnings per share to grow substantially in the next fiscal year. This valuation is attractive compared to peer averages. The market appears to be offering the stock at a discount to its future earnings potential, making this a clear "Pass".
While the dividend is well-covered and growing, significant shareholder dilution from a large increase in shares outstanding results in a poor overall capital return yield.
OSBC offers a dividend yield of 1.51%, which is modest compared to the regional banking average. However, the dividend's safety is a strong positive, demonstrated by a very low payout ratio of 16.92%. This low ratio indicates that earnings comfortably cover the dividend payments, providing a cushion and potential for future increases. Indeed, the dividend grew by an impressive 19.05% in the last year. The negative aspect of this factor is the substantial increase in shares outstanding. In the most recent quarter, the share count grew by 17.14%, leading to a negative buyback yield (dilution) of -4.68%. This level of dilution is a significant cost to existing shareholders, as it reduces their ownership percentage and claim on future earnings. This high rate of share issuance overrides the positives of the dividend, leading to a "Fail" for this factor.
OSBC's key valuation multiples, including a forward P/E of 8.78x and a P/TBV of 1.37x, appear favorable when compared to general industry benchmarks for regional banks.
This factor assesses how OSBC stacks up against its direct competitors on key metrics. The bank’s trailing P/E of 12.56x is in line with the industry. Its forward P/E of 8.78x suggests it is cheaper than many peers based on future earnings estimates. The P/TBV ratio of 1.37x also compares favorably to the sector median, which has been trending higher. While its dividend yield of 1.51% is below the peer average, its low beta of 0.8 suggests lower-than-market volatility. Overall, the snapshot indicates that OSBC is not expensive relative to its peers, especially when considering its forward earnings potential. Therefore, it passes this relative check.
The primary macroeconomic risk for Old Second Bancorp is its sensitivity to interest rates and the health of the U.S. economy, particularly in its home market of Illinois. If interest rates remain elevated, the bank will continue to face high costs for deposits as it competes with high-yield savings accounts and money market funds. This pressure can squeeze its net interest margin (NIM), which is a key measure of bank profitability. Furthermore, a potential economic slowdown or recession would directly impact the ability of its local customers and businesses to repay their loans, leading to an increase in credit losses and hurting the bank's bottom line. Because the bank's operations are geographically concentrated, it lacks the diversification to offset a downturn specific to the Chicagoland region.
From an industry perspective, Old Second operates in a fiercely competitive environment. It contends with money-center banks like JPMorgan Chase and Bank of America, which have vast resources, national brand recognition, and advanced digital platforms that can attract younger customers. At the same time, nimble fintech companies are chipping away at traditional banking services like payments and personal loans. This competitive landscape forces OSBC to continuously invest in technology to remain relevant, which can be costly for a smaller institution. Additionally, the regulatory environment for banks remains stringent, especially after the regional bank turmoil in 2023. Increased capital requirements or compliance costs could limit the bank's ability to lend and grow in the future.
Company-specific risks are centered on Old Second's loan portfolio. Like many regional banks, OSBC has a notable exposure to Commercial Real Estate (CRE) loans. The CRE market, especially for office and some retail properties, faces significant headwinds from the rise of remote work and e-commerce, combined with the difficulty of refinancing maturing loans at much higher interest rates. A decline in property values or an increase in borrower defaults within this portfolio represents the single most significant risk to the bank's asset quality. While OSBC's growth has been supported by acquisitions, such as the 2021 purchase of West Suburban Bancorp, future M&A activity carries integration risk and there is no guarantee that suitable targets will be available to fuel further expansion.
