South Plains Financial (SPFI) Q1 2026 earnings review
Margin Expansion Shines as Transformational M&A Closes
South Plains Financial delivered a highly profitable Q1 2026, generating $14.5 million in net income ($0.85 EPS) and expanding its Net Interest Margin to a robust 4.04%. While management touted its 'organic growth strategy,' actual loan balances shrank by $41 million sequentially due to persistent multi-family payoffs. However, this organic stagnation is heavily overshadowed by the April 1st closing of the Bank of Houston (BOH) acquisition, which immediately bolts on $685 million in assets and fundamentally upgrades SPFI's scale and product capabilities across Texas. With deposit costs falling below 2% and asset quality reaching pristine levels, the bank enters its post-M&A integration phase from a position of exceptional balance sheet strength.
🐂 Bull Case
The successful closing of the BOH Holdings acquisition on April 1 adds $632M in loans and $596M in deposits, instantly solving the bank's organic loan growth struggles and expanding its Texas footprint.
Average cost of deposits dropped to 1.97%, down 22 bps year-over-year. A high concentration of noninterest-bearing deposits (25.7%) continues to act as a powerful anchor, allowing NIM to expand to 4.04%.
🐻 Bear Case
Despite ongoing lender hiring initiatives, total loans HFI contracted by 1.3% sequentially. A $29.7M multi-family payoff completely negated new production, exposing a persistent vulnerability in the legacy portfolio.
Noninterest expense jumped $2.5M sequentially to $35.5M. While $1.5M was tied to M&A, the remainder reflects rising personnel costs that will pressure efficiency ratios if organic top-line growth doesn't accelerate.
⚖️ Verdict: 🟢
Bullish. The legacy bank is highly profitable with pristine credit and an expanding margin. The BOH acquisition serves as a massive catalyst that instantly solves the organic growth bottleneck.
Key Themes
Transformational M&A Execution: Bank of Houston
Management executed its long-discussed M&A strategy by officially closing the BOH Holdings acquisition on April 1, 2026. This is a massive growth driver that instantly injects $685.0 million in total assets, $631.9 million in loans, and $595.6 million in deposits into the balance sheet for Q2. This fundamentally alters the bank's earnings trajectory and provides critical scale in competitive Texas metro markets.
Relentless Deposit Cost Management
Accelerating. SPFI's core deposit franchise remains its biggest competitive advantage. Average cost of deposits fell to 197 basis points in 26Q1, down from 201 bps in 25Q4 and 219 bps a year ago. Aided by $1.03 billion in noninterest-bearing deposits (25.7% of total), this disciplined funding base drove Net Interest Margin (TE) up to 4.04%.
Asset Quality Reaches Pristine Levels
Stable and excellent. Credit metrics are arguably the strongest they have been in recent history. Nonperforming assets to total assets plummeted to just 0.13% (down from 0.26% in Q4 and 0.58% a year ago). Net charge-offs were a negligible 0.04% annualized, allowing the bank to release earnings power by dropping its quarterly provision for credit losses to just $260,000.
Data Contradiction: 'Organic Growth' vs Loan Contraction
CEO Curtis Griffith touted the execution of their 'organic growth strategy,' yet the data shows total loans Held For Investment actually contracted by $41.0 million (-1.3%) sequentially. As seen in previous quarters (Q2'25, Q3'25), large multi-family property payoffs—specifically a $29.7 million early payoff this quarter—are chronically erasing new lender production.
Macroeconomic Chills and Loan Demand
Management explicitly cited the 'uncertain' near-term economic environment as a direct headwind to loan growth. With seasonal agricultural paydowns ($24.4 million) compounding the real estate payoffs, macro caution is preventing the legacy portfolio from achieving escape velocity prior to the BOH integration.
Volatility in Non-Core Revenue Products: SBIC and MSRs
Noninterest income results highlight reliance on volatile, specific financial products. Q1 saw an $801 thousand loss in a Small Business Investment Company (SBIC) fund due to poor underlying company performance. This was offset by a $250 thousand upward fair value adjustment on Mortgage Servicing Rights (MSRs)—a reversal from a $665 thousand write-down in Q4. This volatility masks the true run-rate of core fee generation.
Expense Base Steps Up
Noninterest expense accelerated to $35.5 million, up $2.5 million from Q4. While $1.5 million was directly tied to BOH acquisition professional services, the remaining $1.0 million increase was driven by annual salary adjustments and the new lender hiring initiative. Operating leverage will need to be monitored closely as BOH personnel are onboarded in Q2.
Other KPIs
Accelerating. TBVPS grew 13.8% year-over-year from $26.05 in 25Q1, and is up sequentially from $29.05. This was driven by robust retained earnings generation ($11.8 million in net income after dividends), proving the bank is successfully accreting capital while simultaneously funding cash acquisitions and dividends.
Accelerating. Deposits increased by $153.5 million (4.0%) sequentially, driven by broad-based organic growth across retail, commercial, and public funds. This massive influx of liquidity positions the bank perfectly to fund the new loans coming onto the books from the BOH acquisition without needing to tap wholesale borrowing.
Guidance
While forward numerical guidance was not explicitly provided for the legacy business, management quantified the Day 1 impact of the BOH acquisition. Adding $685M in assets to the Q1 base of $4.64B represents an immediate ~15% step-up in the bank's total asset base for the coming quarter.
The addition of $631.9 million in BOH loans will instantly reverse the bank's recent trend of sequential loan contraction, bringing the combined loan portfolio to roughly $3.73 billion and dramatically increasing the bank's core interest-earning asset base.
Key Questions
BOH Integration and Expense Run-Rate
With the Bank of Houston acquisition closing April 1, what is the expected consolidated quarterly expense run-rate going forward, and what specific cost synergies have been modeled for the back half of 2026?
Defending the Multi-Family Portfolio
The bank suffered another large ($29.7M) early payoff in the multi-family portfolio this quarter. Is the bank intentionally letting these credits walk to reduce CRE concentration, or are competitors simply offering refinancing terms that SPFI is unwilling to match?
Deposit Cost Floor
The average cost of deposits has successfully fallen below 2.00% (197 bps). Given current rate expectations, how much further room does management see to actively manage deposit costs down before risking core deposit flight?
SBIC Investment Visibility
The $801k loss in the SBIC investment was a surprise drag on noninterest income. What is the total carrying value of remaining SBIC investments, and should investors expect further volatility from this portfolio?
