South Plains Financial (SPFI) Q1 2026: BOH Acquisition Adds $632M Loans, Sets Stage for Margin Optimization
South Plains Financial’s first quarter was defined by the completed Bank of Houston acquisition, disciplined credit management, and a sharpened focus on organic loan growth in Texas. Management emphasized margin stability and cost of funds optimization while integrating BOH, with tangible early progress on deposit mix and liquidity. Looking forward, SPFI’s ability to maintain credit quality and deliver on loan growth targets amid macro headwinds will be the critical investor watchpoint.
Summary
- BOH Integration Drives Scale: Bank of Houston acquisition expands Houston presence and introduces $632M in loans, with cost synergies and balance sheet optimization underway.
- Loan Growth Guidance Intact: Despite multifamily payoffs and seasonal ag trends, management remains confident in achieving low to mid-single-digit organic loan growth for 2026.
- Margin Focus Amid Macro Uncertainty: Leadership prioritizes net interest margin (NIM) preservation and cost of funds management as inflation and rate volatility persist.
Performance Analysis
SPFI posted a resilient first quarter, highlighted by strong profitability, stable net interest margin, and meaningful non-interest income contribution. The completed Bank of Houston (BOH) acquisition added $632 million in loans and $596 million in deposits, with integration progressing on schedule and initial steps taken to reduce non-core funding costs. Core net interest margin (NIM) for the consolidated bank was 4.02% pro forma, with management emphasizing a steady approach to margin preservation rather than chasing short-term gains. Deposit growth was robust in Q1, up 4% sequentially, supported by balanced inflows across retail, commercial, and public funds, though some outflows are expected in Q2 due to tax seasonality.
Loan balances contracted by $41 million quarter-over-quarter, primarily reflecting the anticipated payoff of a large multifamily credit and seasonal paydowns in agriculture. Unfunded loan commitments grew, driven by recent lender hires, particularly in construction lending. Non-interest income, at 21% of revenues, was stable, with mortgage banking showing resilience despite a challenging rate environment. Credit quality improved, with non-performing loans and net charge-offs both declining, while the allowance for credit losses remained steady at 1.44% of loans. Non-interest expense rose due to acquisition-related costs and annual compensation adjustments.
- Deposit Mix Shift: Non-interest-bearing deposits held at 25.7% of total, supporting funding cost discipline as BOH integration proceeds.
- Loan Yield Resilience: Yields held steady at 6.83%, aided by portfolio mix and exception-based pricing, despite some repricing headwinds from Fed actions.
- Mortgage Banking Stability: The mortgage business remained profitable, with management focused on maintaining operational efficiency and readiness for volume recovery when rates decline.
SPFI’s capital position remains robust, with tangible book value per share rising and the board authorizing a 17-cent quarterly dividend for the 28th consecutive quarter. The quarter’s results underscore management’s commitment to organic growth, disciplined M&A, and shareholder returns.

Strategic Positioning
1. BOH Acquisition and Integration
The Bank of Houston deal is central to SPFI’s 2026 strategy. The transaction brings scale in Houston, a key Texas market, and initial integration steps have focused on reducing brokered and high-cost funding. Management expects the core conversion in early May, aiming for a smooth customer and employee transition. The deal is projected to be 11% accretive to earnings by 2027, with a tangible book value earn-back under three years, underscoring its strategic and financial rationale.
2. Organic Growth and Talent Acquisition
SPFI’s organic growth hinges on targeted hiring of experienced lenders in Dallas, Houston, and Midland. About half of the planned hiring is complete, with new bankers contributing to a healthy loan pipeline, especially in construction and owner-occupied segments. The bank’s community focus and product breadth position it as a preferred partner amid ongoing Texas banking consolidation.
3. Margin and Cost of Funds Discipline
Management is prioritizing cost of funds optimization by gradually replacing non-core and expensive deposits with core relationships, particularly in Houston. While opportunities exist to lower BOH’s funding costs, the impact on group-wide margin will be incremental. Net interest margin stability is the guiding principle, with leadership resisting aggressive tactics that could erode long-term profitability.
4. Credit Quality and Risk Management
SPFI maintains a conservative credit profile, with improving asset quality and a measured approach to loan growth. The bank avoids higher-risk specialized lending, focusing on sectors where it has deep expertise. Multifamily exposures are typically short-term, with payoffs anticipated and replaced through strong client relationships. Energy exposure remains under 5% of the portfolio and is concentrated in C&I servicing, not upstream risk.
5. Non-Interest Income Diversification
Mortgage banking continues to be a positive contributor, with management focused on efficiency and readiness for a market rebound. Non-interest income remains a key pillar, representing 21% of revenues, and leadership is committed to expanding this stream to reduce reliance on spread income.
Key Considerations
Q1 2026 was a pivotal quarter for SPFI, with the BOH acquisition setting the stage for scale, while operational discipline and credit conservatism remain at the forefront. The following considerations frame the bank’s outlook:
Key Considerations:
- Houston Market Expansion: BOH integration provides a larger footprint in a growth market, but successful deposit and loan retention will be critical for realizing projected synergies.
- Cost of Funds Pressure: While steps are underway to reduce non-core funding, competitive deposit pricing in Texas could limit near-term improvement.
- Loan Growth Execution: Multifamily payoffs and ag seasonality are headwinds, but a robust pipeline and new hires support guidance for low to mid-single-digit growth.
- Credit Quality Vigilance: Conservative underwriting and sector discipline help limit risk, but macro volatility and energy price swings warrant ongoing monitoring.
- Non-Interest Income Focus: Mortgage banking remains stable, but meaningful upside depends on rate declines and housing market recovery.
Risks
SPFI faces several risks as it scales: Elevated energy prices and geopolitical uncertainty could pressure Texas economic activity and limit loan growth. Intense deposit competition may constrain cost of funds improvement, especially as BOH’s funding mix transitions. Multifamily and ag loan payoffs could challenge organic growth targets if not offset by new business. Integration missteps or customer attrition post-acquisition could erode projected synergies. Management’s conservative approach mitigates some risks, but macro and competitive dynamics remain material variables.
Forward Outlook
For Q2 2026, SPFI expects:
- Deposit growth to be flat to down due to seasonal tax outflows, with a return to growth in the second half of the year (excluding acquisition impact).
- Cost of funds to remain steady, barring further Fed rate action, with incremental improvement as non-core funding is replaced.
For full-year 2026, management reaffirmed guidance:
- Low to mid-single-digit organic loan growth, with confidence in the pipeline despite early-year payoffs.
Management highlighted disciplined M&A, ongoing hiring, and a focus on margin and credit quality as central to delivering on full-year targets.
- Deposit and loan retention in Houston post-BOH integration will be closely watched.
- Macro headwinds, including inflation and energy price volatility, remain key external variables.
Takeaways
SPFI’s Q1 2026 results reflect a bank in transition, balancing scale from M&A with organic discipline and margin vigilance.
- BOH Integration Sets Foundation: Early steps to optimize funding and integrate teams are progressing, but long-term success depends on relationship retention and synergy realization.
- Margin and Credit Quality Drive Stability: Management’s focus on NIM preservation and conservative lending underpins profitability and risk management.
- Loan Growth and Non-Interest Income Remain Key Levers: Execution on hiring and pipeline conversion, along with mortgage banking resilience, will determine SPFI’s ability to deliver on 2026 targets.
Conclusion
South Plains Financial enters the remainder of 2026 with increased scale, a disciplined approach to integration, and a clear focus on margin and credit quality. The BOH acquisition is a catalyst for future growth, but execution on deposit retention, loan growth, and cost of funds optimization will determine the ultimate value delivered to shareholders.
Industry Read-Through
SPFI’s Q1 underscores several broader banking themes: Regional banks expanding through disciplined M&A, especially in high-growth markets like Texas, are prioritizing relationship retention and funding mix optimization over rapid balance sheet expansion. Deposit competition remains intense, and cost of funds management is a central battleground as rate volatility persists. Community banks with strong local teams and conservative credit cultures are well-positioned, but must balance growth aspirations with risk discipline as macro headwinds and sector consolidation continue. Mortgage banking stability in a tough rate environment signals the value of scale and operational efficiency for non-interest income streams.
