RBB Bancorp is a bank holding company that owns and oversees its banking subsidiary Royal Business Bank and its asset management subsidiary RBB Asset Management Company. The company was formed in January 2011 and has grown through a combination of organic expansion and strategic acquisitions. Royal Business Bank operates as a full service bank that provides commercial and consumer banking products to customers in multiple states. RBB Asset Management Company was established in 2012 to hold and manage problem assets obtained from acquisitions, though it presently holds no significant problem assets and conducts limited activity. RBB Bancorp maintains its status as a minority depository institution, with at least 51% of its voting stock owned by minority individuals.
Revenue is derived mainly from interest income on loans and, to a lesser extent, from interest on investment securities. The loan portfolio includes single family residential mortgages, commercial real estate loans, construction and land development loans, commercial and industrial loans, and Small Business Administration loans. Noninterest income is generated from fees on deposit accounts, loan servicing charges, gains on loan sales, and wealth management services. As of December 31, 2025, the company reported total consolidated assets of $4.2 billion, gross consolidated loans of $3.3 billion, and deposits of $3.4 billion. Shareholders’ equity amounted to $523.4 million at the same date.
The company operates through the following segments.
• Royal Business Bank: Provides a full range of business and consumer banking products, including commercial real estate loans, construction and land development loans, commercial and industrial loans, SBA loans, residential mortgages, and deposit services to primarily Asian centric communities across multiple states.
• RBB Asset Management Company: Holds and manages problem assets acquired through acquisitions, although it currently has no significant problem assets or active operations.
RBB Bancorp operates in the Asian centric banking market where it competes with publicly traded banks, locally based banks, and subsidiaries of Taiwanese or Chinese banks. Its minority depository institution status grants access to FDIC technical assistance and underscores its commitment to serving minority communities. The bank’s loan portfolio is well diversified, with residential mortgages representing approximately 50.0% of total loans and commercial real estate accounting for about 39.3% as of December 31, 2025. Construction and land development loans make up roughly 4.7%, commercial and industrial loans about 4.2%, and Small Business Administration loans around 1.7% of the portfolio. Strong capital ratios that exceed the well capitalized thresholds under Basel III, a stable deposit base with 80.6% of relationships meeting stability criteria, and an experienced management team further enhance its competitive position.
The bank’s customers are primarily small to middle sized businesses and individuals. These customers are largely located in Asian centric communities served by branches in California, Nevada, New York, Illinois, New Jersey and Hawaii. In addition, the bank serves municipalities and other entities that seek traditional deposit, treasury management, and wealth management services.

Investment Thesis
▲ Bull case
RBB's residential mortgage portfolio represents a significant competitive advantage that remains underappreciated by the market. With $1.7 billion in well-secured non-QM mortgages concentrated in high-value markets like New York and California and an average LTV of just 54%, this portfolio provides exceptional credit quality and stability. The low LTV creates substantial equity cushions that protect against downturns, while the geographic concentration in resilient housing markets supports consistent performance. This segment generates reliable interest income with minimal credit risk, forming a durable foundation for earnings that is less sensitive to economic cycles than commercial lending. Management's disciplined underwriting in this area has produced a portfolio that outperforms many peers in risk-adjusted returns, yet the market continues to focus disproportionately on the bank's historical commercial credit challenges. As residential mortgage demand remains robust due to housing shortages in key markets, this segment offers predictable growth potential that could drive consistent mid-single-digit loan expansion even if commercial activity moderates. The portfolio's performance also enhances the bank's overall risk profile, potentially justifying a higher valuation multiple as investors recognize the reduced earnings volatility. Furthermore, the bank's ability to originate mortgages at yields 31 basis points above portfolio yield demonstrates pricing power in this segment, suggesting opportunities to further enhance profitability through selective growth in higher-margin residential products.
The resolution of nonperforming assets presents a substantial hidden catalyst that could meaningfully boost earnings beyond current expectations. Management revealed that 90% of nonperforming loans are concentrated in just four relationships, with three currently making payments under workout agreements and only one (a partially completed construction project) presenting significant complexity. This concentration implies that resolving these assets could quickly return over $50 million to earning asset status, directly increasing net interest income without requiring new loan origination. The bank has already reduced nonperforming loans by 45% and nonperforming assets by 34% year-over-year, demonstrating proven capability in workout management. With expectations that the majority of resolutions could occur in the first half of 2026, this process could provide an immediate and significant boost to profitability. Importantly, resolving these assets would also reduce the provision for credit losses, which totaled $600,000 in Q4 2025 primarily due to charge-offs and loan growth. As these problem assets are resolved, the bank could experience a dual benefit: higher interest income from returned earning assets and lower credit costs, potentially expanding net margins beyond what is currently modeled. The market appears to be pricing in only gradual improvement, but the concentrated nature of the problem suggests a faster-than-expected turnaround that could surprise to the upside.
RBB's deposit franchise shows signs of stabilizing and improving in ways that could support sustained margin expansion, contrary to near-term pessimism about rate sensitivity. While deposit betas have risen recently, management highlighted that 99.5% of the $1.7 billion in CDs will mature within the next 12 months, with 40% maturing in Q1 2026 alone. These CDs are currently priced in the high 3% range, while market rates have fallen to around 3%, creating a significant opportunity for repricing at lower costs as these instruments roll over. This dynamic suggests that deposit costs could decline more rapidly than anticipated, especially given the bank's success in growing interest-bearing nonmaturing deposits and retail relationships. The shift from traditional CDs to more flexible non-maturity products also provides strategic advantages in a falling rate environment, allowing for better asset-liability management. Combined with the bank's demonstrated ability to maintain loan yields (which actually increased 4 basis points year-over-year in Q4 despite Fed cuts), this sets the stage for meaningful net interest margin expansion. The current market focus on near-term margin pressure overlooks the powerful tailwind from the impending repricing of a massive, high-cost CD book, which could drive disproportionate improvement in profitability as 2026 progresses.
Capital flexibility represents an underleveraged strength that could drive shareholder returns and support growth initiatives. RBB ended 2025 with tangible book value per share at $26.42, up 7.8% for the year, while returning over $25 million to shareholders through dividends and repurchases (approximately 4% of outstanding shares). The bank maintains capital ratios well above regulatory minimums, indicating substantial excess capital that remains underutilized. Management explicitly linked future buyback activity to the resolution of subordinated debt, noting that rightsizing the $120 million sub debt eligible for redemption in April 2026 would create capacity for more aggressive share repurchases. This sequencing suggests that once the capital structure is optimized, the bank could significantly accelerate returns to shareholders. Additionally, the strong capital position provides a buffer for absorbing any unexpected credit losses while simultaneously funding growth initiatives, reducing the need to rely on costly wholesale funding. The ability to deploy excess capital through buybacks not only enhances earnings per share but also signals confidence in intrinsic value, potentially attracting long-term investors. With the subordinated debt repricing decision imminent, the pathway to increased capital return is clear and near-term, offering a tangible catalyst that the market may not be fully incorporating into current valuations.

RBB's loan growth momentum is showing signs of fragility that could persist into 2026, undermining the bank's ability to achieve its stated growth targets. Management acknowledged that fourth-quarter loan growth slowed to low single digits, attributing it to a combination of payoffs, lower demand, and deposit constraints exacerbated by a loan-to-deposit ratio near 99%. While the pipeline appears healthy, the reliance on loan sales to offset organic growth weakness raises concerns about sustainability, as selling loans converts potential interest income into one-time gains without contributing to long-term earnings power. The bank's commercial lending efforts face increasing competitive pressure, with peers offering 5-year fixed rates below 5.75% while RBB struggles to maintain yields above 6%, suggesting it may be losing market share on price-sensitive transactions. Furthermore, the emphasis on relationship-based lending, while valuable, may limit scalability in a rate-sensitive environment where borrowers are increasingly driven by cost. If deposit costs fail to decline as rapidly as hoped due to persistent competition for funds, the bank could find itself unable to fund loan growth at attractive margins, creating a self-reinforcing cycle where growth stalls not from lack of demand but from unprofitable pricing. This dynamic risks leaving RBB behind competitors who can grow more efficiently in the current rate environment.
The bank's deposit cost structure remains vulnerable to competitive pressures that could erode margins more severely than management anticipates. Despite expectations of declining costs from CD maturities, Lynn Hopkins acknowledged that 'competition remains intense' and recent rate cuts have not delivered the same pace of reduction in deposit costs as seen previously. The 30% deposit beta on interest-bearing products in the latest quarter — significantly lower than the 70% year-over-year figure — indicates that the bank is losing its ability to pass on rate cuts to depositors, likely due to aggressive pricing by competitors for retail deposits. With average demand deposits comprising only 16% of total deposits, the bank remains heavily reliant on rate-sensitive funding, and any failure to reduce costs could quickly reverse the modest margin improvements seen in recent quarters. The shift toward non-maturity interest-bearing products, while intended to increase flexibility, may actually increase beta in a falling rate environment if these products reprice more quickly than anticipated. Moreover, the bank's success in growing retail deposits has come at a cost, as evidenced by the declining trend in deposit costs not keeping pace with market rates. If this trend continues, the bank could face a scenario where asset yields fall faster than funding costs, compressing margins despite loan growth — a classic liability-sensitive outcome that would directly contradict management's expectations for NIM expansion.
Credit quality improvements, while real, may be overstated and susceptible to reversal, particularly given the unresolved complexities in the remaining problem loans. Although nonperforming loans decreased 45% year-over-year, 90% of the residual exposure is tied to just four relationships, with one — a partially completed construction project — representing half of the balance and expected to take the longest to resolve. This concentration creates significant idiosyncratic risk: if this single project encounters delays, cost overruns, or fails to meet revised work-out terms, it could trigger a disproportionate increase in nonperforming assets. Furthermore, the bank's reliance on borrowers making payments under workout agreements (three of the four relationships) introduces execution risk; any deterioration in these borrowers' financial conditions could quickly reverse progress. The provision for credit losses remained elevated at $600,000 in Q4 2025, driven by charge-offs and loan growth, suggesting that underlying credit stress may not be fully resolved. Management's optimism about resolving these assets in the first half of 2026 appears aggressive given the complexity of the construction project, and any delay would prolong the drag on earnings from both impaired assets and ongoing reserve requirements. The market may be underestimating the potential for these credit issues to linger or worsen, especially if broader economic conditions deteriorate unexpectedly.
Operating expenses pose a persistent headwind that could constrain profitability and limit the bank's ability to reinvest in growth, despite hopes for declines in legal and professional fees. While management expects some reduction in these costs as credit stabilizes, the run rate remains elevated at $18–$19 million per quarter, with first-quarter expenses expected to increase further due to seasonal taxes and salary adjustments. The acknowledgment that 'legal and professional has been maybe more elevated than past years' implies that these costs were anomalously high in 2025 due to workout activities, but even a return to prior levels may not translate to meaningful savings if other cost categories absorb the difference. More concerning is the admission that achieving mid- to high single-digit loan growth may require the same elevated expense levels seen in 2025, suggesting that the bank's cost structure is inherently inefficient relative to its revenue generation. The management transition noted as a one-time factor may also mask underlying inefficiencies, and the expectation that expenses will stabilize in the $18–$19 million range implies a fixed cost base that requires significant revenue growth just to maintain current profitability. Without material operating leverage, any slowdown in revenue growth would quickly translate to declining earnings, making the bank vulnerable to even modest setbacks in its core operations.
