South Plains (SPFI) Q2 2026 earnings review
M&A Execution Supercharges Revenue, But Margin Dilution Creeps In
South Plains delivered a transformative Q2, characterized by the successful integration of the Bank of Houston (BOH). This single transaction catalyzed a 30% YoY jump in Net Income to $19.0 million and pushed total loans to $3.77 billion. The long-term organic strategy also bore fruit, generating $35.4 million in net organic loan growth despite $37.5 million in strategic payoffs. However, the top-line explosion masks an underlying margin headwind: BOH's funding base is noticeably more expensive, driving total deposit costs up 11 bps sequentially and slightly compressing the Net Interest Margin to 4.00%.
🐂 Bull Case
The addition of $631.9M in loans and $595.6M in deposits from BOH immediately accreted to the bottom line, driving EPS up from $0.85 sequentially to $0.96.
After quarters of elevated payoffs stunting net loan growth, the company generated $35.4M in organic loan growth this quarter, proving the aggressive lender hiring strategy is yielding results.
🐻 Bear Case
The cost of average deposits spiked 11 bps sequentially to 208 bps, directly attributed to the higher-cost deposit base acquired from BOH.
Noninterest expense jumped $4.3M sequentially. Even stripping out $1.1M in M&A costs, core operating expenses surged $2.7M due to annual salary adjustments and new hires.
⚖️ Verdict: 🟢
Bullish. Management successfully integrated a major acquisition while simultaneously reversing the organic loan contraction trend. If they can extract funding synergies from BOH to stabilize margins, the earnings runway is highly attractive.
Key Themes
Bank of Houston Integration Validates M&A Strategy
The April 1st closing of the BOH acquisition was the undisputed catalyst for the quarter, adding approximately $667 million in interest-earning assets. This drove a massive acceleration in total loans held for investment, surging from $3.10 billion to $3.77 billion sequentially. The immediate jump in top-line interest income validates management's thesis that strategic consolidation in the Texas market can rapidly scale the balance sheet.
Organic Loan Growth Trend Reversing Positively
For the past year, aggressive organic loan production was continuously offset by elevated, planned multifamily payoffs. This quarter marks a Reversing trend: despite $37.5 million in large loan payoffs, the bank managed to post $35.4 million in net organic growth. This confirms that the heavily invested strategy of hiring up to 20% more experienced lenders in high-growth Texas markets is beginning to outpace portfolio runoff.
Bank Card Services and Noninterest Income Acceleration
A specific product bright spot was the acceleration in noninterest income, up $2.8 million sequentially. This was heavily driven by specific adoption in Bank Card Services and interchange revenue, which grew by $894 thousand. Management attributes this to continued growth in customer card usage and incentive optimization, highlighting successful digital product adoption alongside traditional lending.
Macro Pressures on Mortgage Reversing Favorable
Despite a tough macro environment for originations, mortgage banking revenues accelerated, jumping $929 thousand sequentially and $1.2 million YoY. This was aided by a favorable $515 thousand MSR fair value write-up (driven by interest rate volatility) but also by tangibly improved origination volumes.
NIM Compression Contradicts Headline Revenue Surge
While total interest income exploded to $75.0 million, the underlying profitability of those assets decelerated. The tax-equivalent Net Interest Margin (NIM) compressed from 4.04% to 4.00% QoQ. This explicitly contradicts the purely bullish top-line narrative, demonstrating that the newly acquired BOH assets came with a significantly heavier liability burden.
Deposit Costs Accelerating Due to M&A
The macro environment for deposits remains intensely competitive, but the bank's M&A actions directly worsened their funding profile this quarter. The average cost of deposits jumped 11 bps sequentially to 2.08%, entirely attributed by management to the higher cost of BOH acquired deposits. The optimization of this specific liability pool is the most critical hurdle for future margin expansion.
Core Operating Expenses Surging
The aggressive hiring strategy and M&A integration are significantly inflating the cost base. Noninterest expense accelerated to $39.9 million. Beyond the $1.1 million in one-time M&A costs, core operating expenses spiked by $2.7 million sequentially. With the efficiency ratio tracking upward, the bank must prove these new hires can generate sufficient revenue to cover their escalating compensation.
Other KPIs
Stable to improving relative to historicals. While slightly up sequentially from $260k, it represents a massive deceleration from the $2.5 million provision recorded in 25Q2, underscoring stable overall credit quality even as the loan book scales dramatically.
Stable, but warrants monitoring. This metric ticked up from 0.13% in 26Q1 but remains down from 0.25% in 25Q2. The absorption of the BOH portfolio will require strict credit discipline to ensure this metric does not revert to an accelerating trend.
Stable sequentially (down slightly from $29.65 in Q1) due to the issuance of 2.8 million shares at $41.90 for the BOH acquisition. However, it reflects impressive 11% YoY growth from $26.70 in 25Q2.
Guidance
Management abstained from providing explicit numerical guidance in the Q2 press release, emphasizing a qualitative focus on integrating the BOH acquisition. The stated priority is optimizing the higher-cost deposit base acquired from BOH to relieve margin pressure, and letting the newly deployed lender teams ramp up production.
Key Questions
BOH Deposit Repricing Timeline
With the BOH acquisition driving a clear 11 bps sequential increase in the average cost of deposits, what is the specific timeline and strategy to reprice these funds downward, and when can we expect NIM expansion to resume?
Core Expense Run-Rate
Core operating expenses grew $2.7M sequentially independent of direct M&A charges. As you finalize your aggressive lender hiring initiative, is $40M an appropriate run-rate for quarterly noninterest expense, or are there post-integration cost synergies yet to be realized?
Organic Growth Targets
Now that you have achieved positive net organic loan growth ($35.4M) despite ongoing strategic payoffs, do you expect this velocity to accelerate in the second half of 2026 as recent hires fully mature their books?
Credit Quality Post-M&A
NPAs ticked up sequentially to 0.19%. Were any specific portfolios within the newly acquired $632M BOH loan book responsible for this slight degradation, or is this merely standard baseline seasoning?
