Second Quarter 2026 Highlights

Curtis Griffith, South Plains’ Chairman and Chief Executive Officer, commented, “We delivered a strong second quarter highlighted by solid profitability, stable credit quality and the successful integration of Bank of Houston, which has strengthened our position in Houston, one of Texas’ most attractive banking markets. As I prepare to retire as Chief Executive Officer at year-end, I am incredibly proud of what our employees have accomplished and the Company we have built together over the past four decades. The Bank is in a position of strength, and our leadership transition reflects years of thoughtful planning designed to ensure continuity for our customers, employees and shareholders. I remain highly confident in South Plains’ future and believe Cory is the right leader to guide the organization as we continue to grow earnings, deepen customer relationships and build on the culture that has been central to our success. I look forward to continuing to serve as Chairman of South Plains and City Bank as Cory and our talented leadership team build on our momentum and execute the next phase of our growth strategy.”

Cory Newsom, South Plains’ President, added, “I am honored by the Board’s confidence and am excited to lead South Plains into its next chapter. Our second quarter results demonstrate the strength of our relationship-based banking model, disciplined credit culture and proven growth strategy. Looking ahead, we remain focused on expanding our lending platform in high-growth Texas markets, attracting experienced bankers who fit our culture, optimizing the Bank of Houston acquisition and pursuing disciplined growth opportunities that enhance long-term shareholder value. With a strong balance sheet, healthy loan pipeline and exceptional team, we believe South Plains is well positioned for continued success.”

Results of Operations, Quarter Ended June 30, 2026

Net Interest Income

Net interest income was $50.3 million for the second quarter of 2026, compared to $42.9 million for the first quarter of 2026 and $42.5 million for the second quarter of 2025. Net interest margin, calculated on a tax-equivalent basis, was 4.00% for the second quarter of 2026, compared to 4.04% for the first quarter of 2026 and 4.07% for the second quarter of 2025. The average yield on loans was 6.81% for the second quarter of 2026, compared to 6.83% for the first quarter of 2026 and 6.99% for the second quarter of 2025. The average cost of deposits was 208 basis points for the second quarter of 2026, which is 11 basis points higher than the first quarter of 2026 and 6 basis points lower than the second quarter of 2025. The increase from the first quarter of 2026 was due to the higher cost of deposits on the Bank of Houston acquired deposits.

Interest income was $75.0 million for the second quarter of 2026, compared to $62.6 million for the first quarter of 2026 and $64.1 million for the second quarter of 2025. Interest income in the second quarter of 2026 increased $12.4 million compared to the first quarter of 2026 and increased $10.9 million compared to the second quarter of 2025. These increases were primarily due to the acquisition of BOH’s approximately $667 million of interest-earning assets.

Interest expense was $24.7 million for the second quarter of 2026, compared to $19.8 million for the first quarter of 2026 and $21.6 million for the second quarter of 2025. Interest expense in the second quarter of 2026 increased $4.9 million compared to the first quarter of 2026 and increased $3.1 million compared to the second quarter of 2025. These increases were mainly attributable to the acquisition of BOH’s approximately $611 million of interest-bearing liabilities, with the year-over-year comparison being partially offset by interest-bearing deposit growth in the first quarter of 2026.

Noninterest Income and Noninterest Expense

Noninterest income was $14.1 million for the second quarter of 2026, compared to $11.3 million for the first quarter of 2026 and $12.2 million for the second quarter of 2025. The increase from the first quarter of 2026 was primarily due to an increase of $929 thousand in mortgage banking revenues, mainly as a result of improved mortgage originations during the quarter, and an increase of $894 thousand in bank card services and interchange revenue, mainly as a result of continued growth in customer card usage and incentives received during the period. Additionally, there was an $801 thousand loss in a Small Business Investment Company (“SBIC”) investment that lowered other noninterest income in the first quarter of 2026. The increase in noninterest income for the second quarter of 2026 as compared to the second quarter of 2025 was primarily due to an increase of $1.2 million in mortgage banking revenues, mainly as a result of the change in the fair value adjustment of the mortgage servicing rights assets – a write-up of $515 thousand in the second quarter of 2026 compared to a write-down of $156 thousand in the second quarter of 2025 – based on interest rate changes during the respective quarters.

Noninterest expense was $39.9 million for the second quarter of 2026, compared to $35.5 million for the first quarter of 2026 and $33.5 million for the second quarter of 2025. The $4.3 million increase from the first quarter of 2026 primarily resulted from an increase of $2.7 million in core operating expenses related to the recent acquisition and higher incentive-based compensation expense. There was approximately $1.1 million of acquisition-related expenses in the second quarter of 2026, of which $710 thousand was for personnel expenses, compared to $1.5 million in the first quarter of 2026, of which $1.2 million was for professional services. The $6.3 million increase in noninterest expense for the second quarter of 2026 as compared to the second quarter of 2025 was largely the result of the $2.7 million increase in core operating expenses related to the recent acquisition, annual salary adjustments and new lenders hired, and $1.1 million in acquisition-related expenses.

Loan Portfolio and Composition

Loans held for investment were $3.77 billion as of June 30, 2026, compared to $3.10 billion as of March 31, 2026 and $3.10 billion as of June 30, 2025. The increase of $667.3 million during the second quarter of 2026 as compared to the first quarter of 2026 occurred as a result of $631.9 million in loans from the recent acquisition and $35.4 million of organic loan growth during the quarter. The organic growth was net of two loan payoffs totaling $37.5 million during the quarter. As of June 30, 2026, loans held for investment increased $671.9 million as compared to June 30, 2025, primarily as a result of acquisition growth noted above.

Deposits and Borrowings

Deposits totaled $4.64 billion as of June 30, 2026, compared to $4.03 billion as of March 31, 2026 and $3.74 billion as of June 30, 2025. Deposits increased by $613.0 million in the second quarter of 2026 from March 31, 2026. Deposits increased by $901.7 million at June 30, 2026 as compared to June 30, 2025. Noninterest-bearing deposits were $1.15 billion as of June 30, 2026, compared to $1.03 billion as of March 31, 2026 and $998.8 million as of June 30, 2025. Noninterest-bearing deposits represented 24.8% of total deposits as of June 30, 2026. The quarterly and year-over-year change in total deposits was primarily due to $595.6 million in deposits from the recent acquisition. Additionally, the year-over-year change had $288.6 million in organic growth broadly across the deposit portfolio.

Asset Quality

The Company recorded a provision for credit losses in the second quarter of 2026 of $350 thousand, compared to $260 thousand in the first quarter of 2026 and $2.5 million in the second quarter of 2025. The decrease in provision for the year-over-year comparison was largely attributable to activity in the second quarter of 2025 which included an increase in specific reserves, increased loan balances, and several credit quality downgrades.

The ratio of allowance for credit losses to loans held for investment was 1.41% as of June 30, 2026, compared to 1.44% as of March 31, 2026 and 1.45% as of June 30, 2025.

The ratio of nonperforming assets to total assets was 0.19% as of June 30, 2026, compared to 0.13% as of March 31, 2026 and 0.25% as of June 30, 2025. Annualized net charge-offs were 0.06% for the second quarter of 2026, compared to 0.04% for the first quarter of 2026 and 0.06% for the second quarter of 2025.

Capital

Book value per share increased to $33.43 at June 30, 2026, compared to $30.90 at March 31, 2026. The change was primarily driven by the issuance of 2.8 million shares for the BOH acquisition at $41.90 per share. The increase was also the result of $15.7 million of net income after dividends paid during the second quarter of 2026. The ratio of tangible common equity to tangible assets (non-GAAP) stayed essentially flat at 10.47% at June 30, 2026.

These non-GAAP financial measures include Tangible Book Value Per Share, Tangible Common Equity to Tangible Assets, and Pre-Tax, Pre-Provision Income. The Company believes these non-GAAP financial measures provide both management and investors a more complete understanding of the Company’s financial position and performance. These non-GAAP financial measures are supplemental and are not a substitute for any analysis based on GAAP financial measures.

We classify a financial measure as being a non-GAAP financial measure if that financial measure excludes or includes amounts, or is subject to adjustments that have the effect of excluding or including amounts, that are included or excluded, as the case may be, in the most directly comparable measure calculated and presented in accordance with GAAP as in effect from time to time in the United States in our statements of income, balance sheets or statements of cash flows. Not all companies use the same calculation of these measures; therefore, this presentation may not be comparable to other similarly titled measures as presented by other companies.
