Business Overview: OP Bancorp (Nasdaq: OPBK)

---

Executive Summary

OP Bancorp is a California-based bank holding company headquartered in Los Angeles. Its wholly owned subsidiary, Open Bank, is a California state-chartered community bank originally founded in 2005 as First Standard Bank, rebranded as Open Bank in 2010, with the holding company formed in 2016.

Open Bank is a relationship-driven community bank built around small and medium-sized businesses, their owners, and retail customers, with a particular focus on the Korean-American community. It operates twelve full-service branches concentrated in Los Angeles and Orange Counties, with single branches in Santa Clara, CA, Carrollton, TX, and Las Vegas, NV, plus five loan production offices spanning Pleasanton (CA), Atlanta (GA), Aurora (CO), Lynnwood (WA), and Fairfax (VA) — a geographic footprint that follows Korean-American business communities across the country far beyond what its branch count alone would suggest.

OP Bancorp matters less for its size — at roughly $2.7 billion in total assets it is a small-cap community bank — than for its position as a scaled, well-capitalized alternative within a tight-knit ethnic-banking niche, competing for the same depositor and borrower relationships as larger Korean-American-focused peers while differentiating on service and local decision-making.

1. Core Business Model & How They Work

Like any community bank, Open Bank's economics are a straightforward spread business: it gathers low-cost deposits, deploys them into higher-yielding loans, and earns the difference (net interest income), supplemented by fee income from loan sales and service charges.

[ Deposit Gathering ] ➡️ [ Funding Pool (core + wholesale) ] ➡️ [ Loan Origination & Underwriting ] ➡️ [ Net Interest Income ] ➡️ [ Fee Income (SBA loan sales, service charges) ] ➡️ [ Net Income ]

Key Operational Drivers

1. Relationship & Community Banking: Open Bank competes on local decision-making, personal service, and deep familiarity with the Korean-American small-business community rather than on scale or product breadth.
2. Deposit Funding: Core deposits (demand, savings, money market, time deposits) gathered through branches, online, and mobile banking are supplemented with wholesale funding, including brokered deposits, when needed to fund loan growth.
3. SBA Lending as a Fee Engine: As an SBA Preferred Lender, Open Bank originates SBA 7(a) and 504 loans, sells the guaranteed portion of 7(a) loans into the secondary market for gain-on-sale income, and retains servicing rights — a capital-efficient way to grow fee income without carrying full credit risk on its balance sheet.
4. Organic, De Novo Growth: The company has historically grown through opening new branches and loan production offices rather than acquisitions, though it says it may consider M&A opportunistically.
5. Community Reinvestment: Through the Open Stewardship Foundation (established 2011), OP Bancorp has committed to donating 10% of consolidated after-tax net income annually to local nonprofits — roughly $22.1 million donated since inception through year-end 2025, supporting more than 250 organizations. This reinforces the brand loyalty that underpins its deposit-gathering ability in its core community.

3. Competitive Landscape

Open Bank operates in a highly competitive, crowded Southern California banking market and explicitly positions itself as "an alternative to larger Korean-American financial institutions" in its own SEC filings.

Direct Peers

• Hanmi Financial Corporation (Hanmi Bank) — the largest Korean-American-focused bank holding company, with a much larger branch network and balance sheet; the dominant incumbent Open Bank is positioned against.
• PCB Bancorp (PCB Bank) — a closely comparable Los Angeles-based, Korean-American-focused community bank of similar scale, competing for many of the same small-business and SBA relationships.
• RBB Bancorp (Royal Business Bank) — broader Asian-American focus (Chinese-American as well as Korean-American) with a wider multi-state footprint.

Broader Competition

• Large national and regional banks, credit unions, brokerages, mortgage and finance companies, insurers, and online/digital financial firms — many with far greater scale and lower funding costs, per the company's own 10-K.
• The bank states it competes primarily on relationships, local knowledge, responsiveness, risk management, and operational efficiency rather than price or breadth of product.

4. Strategic Strengths & Risks

Strengths (The Moat)

• Niche Community Relationships: Decades of embedded trust within the Korean-American small-business community in Los Angeles and Orange County are difficult for a generic regional bank to replicate quickly.
• SBA Lending Expertise: SBA Preferred Lender status and an established gain-on-sale infrastructure give Open Bank a differentiated, fee-generating niche that smaller community banks often lack.
• Geographic Diversification of Loan Production: Loan production offices in Atlanta, Aurora (Denver), Lynnwood (Seattle), and Fairfax (DC-area) let the bank follow dispersed Korean-American business communities nationally without the fixed cost of full branches.
• Capital Strength: As of year-end 2025, Open Bank's capital ratios (Total capital 13.30%, Tier 1 leverage 9.91% at the bank level) sit comfortably above "well-capitalized" regulatory minimums, providing a cushion through credit cycles.

Risks

• Interest Rate / Margin Compression Risk: Net interest margin, while improving (2.96% in 4Q24 to 3.25% in 4Q25), remains sensitive to deposit cost competition and Fed rate moves; a one-time $739K accrual adjustment on a Federal Reserve account compressed 2Q2026 NIM to 3.08%, illustrating the line's volatility.
• Credit Concentration in CRE/C&I and Geography: Loan quality metrics have been drifting modestly worse — nonperforming loans to gross loans rose from 0.40% (4Q24) to 0.76% (2Q2026), and criticized loans to gross loans rose from 1.00% to 1.46% over a similar period — worth watching given concentration in CRE and small-business lending in a narrow geographic and ethnic customer base.
• Customer Concentration Risk: Deliberate focus on the Korean-American community, while a strength in normal times, means local economic or demographic shifts in that community could disproportionately affect growth and deposit retention relative to a broadly diversified bank.
• Trademark Dependency: Open Bank's use of the "Open Bank" name in the U.S. rests on a perpetual coexistence agreement with Spain's Open Bank S.A., which holds the underlying U.S. trademark; a dispute could, in theory, force a costly rebrand.
• Scale Disadvantage vs. Larger Peers: Competing against Hanmi Financial and other larger regional players with greater resources and lower funding costs caps Open Bank's pricing power on both the loan and deposit sides.

6. Summary Conclusion

OP Bancorp is a straightforward, well-run community bank whose real competitive edge is not scale but niche depth: decades of relationship banking within the Korean-American small-business community in Los Angeles, reinforced by genuine SBA lending expertise and a branch/loan-production footprint that has quietly followed that community to Texas, Nevada, and several other states. Its financial performance — improving NIM, ROA near or above 1%, and ROE in the low teens — reflects a bank executing its niche strategy competently rather than one with any structural cost or scale advantage over larger rivals like Hanmi Financial.

The clearest forward risk is less about any single product and more about concentration: a loan book still leaning on CRE and small-business C&I credit, a deposit base reliant on continued trust within one ethnic community, and a brand name whose use depends on a trademark-sharing agreement with an unrelated Spanish bank. None of these is an imminent threat, but together they define the boundaries of how far Open Bank's relationship-driven moat can realistically extend before it collides with larger, better-capitalized competitors in the same niche.
