South Plains Financial Completes BOH Holdings Merger, Expanding to $744M in Assets

South Plains Financial, Inc. ($SPFI) has successfully completed its merger with BOH Holdings, Inc., a significant consolidation in the regional banking sector that expands the combined entity's asset base and market presence. The transaction, finalized on April 1, 2026, marks a strategic growth milestone for the NASDAQ-listed bank holding company as it integrates BOH's subsidiary Bank of Houston into its existing City Bank operations. The merger brings approximately $744 million in total assets from BOH as of the December 31, 2025 measurement date into the South Plains fold, creating a more robust financial institution positioned for enhanced operational efficiency and market reach.

Merger Details and Structural Integration

The transaction was executed through a clean operational merger structure designed to minimize disruption to customer relationships and banking services. Under the merger framework:

• BOH Holdings, Inc. was merged into South Plains Financial, Inc.
• Bank of Houston, BOH's principal banking subsidiary, was merged into City Bank, South Plains' existing banking subsidiary
• The combined entity continues operating under the South Plains Financial parent company name
• City Bank remains the designated banking subsidiary for the consolidated operations
• BOH's asset base of $744 million (as of December 31, 2025) was integrated into the combined institution

This structural approach allows South Plains to maintain operational continuity while consolidating regulatory oversight, technology infrastructure, and administrative functions. The use of City Bank as the surviving banking entity provides naming consistency and allows the company to leverage existing customer relationships and banking infrastructure across both acquired and legacy operations.

Market Context and Banking Consolidation Trends

The completion of the South Plains-BOH merger reflects broader consolidation trends reshaping the regional banking landscape. As larger financial institutions face heightened regulatory scrutiny and capital requirements following recent banking sector volatility, mid-sized regional banks are increasingly pursuing strategic combinations to achieve scale economies and operational efficiencies.

The regional banking sector has experienced significant M&A activity, driven by several key factors:

• Regulatory pressure on smaller institutions to maintain robust capital ratios and compliance infrastructure
• Technology investment requirements that benefit from scale and combined resources
• Deposit competition intensifying as digital banking and fintech alternatives grow
• Interest rate environment creating margin pressures for traditional banking models
• Customer consolidation trends favoring banks with broader geographic and service footprints

South Plains' acquisition of BOH's $744 million asset base positions the combined institution within a competitive segment of the banking market where scale provides meaningful advantages. The integration of Bank of Houston's customer base and loan portfolio strengthens South Plains' competitive position in Texas markets while potentially creating cross-selling opportunities and operational synergies through consolidated back-office functions.

Investor Implications and Strategic Benefits

For $SPFI shareholders, the BOH merger completion represents the realization of a growth strategy aimed at building a stronger, more diversified regional bank. The transaction delivers several potential benefits to investors:

Operational Synergies: The consolidation of banking subsidiaries eliminates duplicate overhead functions, from information technology to compliance and risk management. These cost reductions typically flow through to improved net interest margins and operational efficiency ratios over time.

Revenue Diversification: The integration of Bank of Houston's customer base and loan portfolio reduces South Plains' dependence on any single market or product line. Enhanced geographic diversification in Texas markets provides more stable earnings across economic cycles.

Scale Advantages: The combined $744 million in assets strengthens the institution's ability to invest in technology infrastructure, enhance digital banking capabilities, and compete for larger commercial clients requiring multi-state banking relationships.

Capital Efficiency: Larger banks typically operate with lower regulatory capital ratios relative to assets, allowing more efficient deployment of shareholder capital for growth initiatives or shareholder returns.

However, investors should monitor integration execution closely. Merger success depends on seamless operational integration, retention of key talent from both institutions, and preservation of customer relationships. Any significant customer attrition, technology integration challenges, or unexpected integration costs could pressure near-term profitability and return on assets metrics.

Forward-Looking Considerations

With the merger now complete, South Plains Financial enters a critical integration phase spanning the next 12-24 months. Management must execute on integration plans while maintaining business momentum and customer service standards. Key metrics investors should monitor include:

• Loan portfolio quality and credit metrics from the combined institution
• Deposit growth and retention rates post-integration
• Net interest margin trends as funding costs normalize
• Efficiency ratio improvements from anticipated cost synergies
• Return on assets and return on equity performance relative to peer benchmarks

The completed BOH Holdings merger strengthens South Plains Financial's market position and asset base as regional banking consolidation continues. Success in integrating Bank of Houston's operations and customer relationships will be critical to realizing the strategic and financial benefits that justified the transaction for shareholders.
