Quarterly Highlights

Statement of Financial Condition

Loans

Loans held for investment increased $95.7 million or 1.99%, 7.99% annualized, from the linked quarter. Loan growth from the linked quarter was largely attributed to originations in the C&I, $69.9 million, and commercial real estate, $76.5 million, portfolios, offset by a $68.6 million reduction in the C&D portfolio. Year-to-date loan growth through June 30, 2023, was $292.6 million, 6.35%, or 12.81% annualized.

The Dallas Fort Worth region produced 59.07% of net loan growth from the linked quarter based on unpaid principal balance, while the North Louisiana and Greater New Orleans regions produced 28.16% and 12.06%, respectively. Based on unpaid principal balances, Texas-based loans represent approximately 37% of the overall loan portfolio as of June 30, 2023.

Credit Quality

The ratios of nonperforming loans compared to loans held for investment and nonperforming assets compared to total assets remained stable from 0.36% and 0.29%, respectively, at March 31, 2023, to 0.36% and 0.30% at June 30, 2023.

Securities

The securities portfolio decreased $26.2 million or 2.90%, from the linked quarter. The decrease was the net impact of negative fair value adjustments, $14.9 million, and net security paydowns and maturities during the quarter. The securities portfolio, based on estimated fair value, represented 13.60% of total assets as of June 30, 2023.

Deposits

Deposits increased $208.3 million or 4.33%, 17.38% annualized, for the quarter ended June 30, 2023. The increase was primarily attributable to the $211.2 million growth in brokered deposits. Excluding the increase in brokered deposits, non brokered deposits remained stable with a decrease of $2.9 million or 0.06%, 0.26% annualized. Year-to-date deposit growth through June 30, 2023, was $194.1 million, 4.03% or 8.12% annualized. Excluding brokered deposits, year-to-date deposits decreased $17.1 million, 0.37% or 0.75% annualized through June 30, 2023, which includes a $40.9 million reduction in FIG deposits.

Noninterest-bearing deposits decreased $46.4 million or 3.14% and interest-bearing deposits increased $254.7 million or 7.65%, compared to the linked quarter. The net growth in interest-bearing deposits was attributable to growth in the certificate of deposit (CD) portfolio of $282.3 million compared to a decrease in transactional accounts of $27.6 million. Brokered deposits accounted for $211.2 million of the $282.3 million increase in the CD portfolio.

As of June 30, 2023, Business First held approximately 104,285 deposit accounts with an average balance of approximately $48,085, of which $1.9 billion or 38.12% were estimated to be uninsured by the FDIC. The average deposit balance excluding brokered deposits was $43,672 per account. Excluding public funds, which are secured by securities or Federal Home Loan Bank (FHLB) letters of credit, the unsecured deposit total was approximately $1.5 billion or 29.26% of total deposits.

Borrowings

Borrowings decreased $57.8 million, or 6.78%, from the linked quarter, these borrowings were replaced with lower cost brokered deposits. Business First repaid $10.0 million in Bank Term Funding Program (BTFP) borrowings and $33.0 million of Federal Home Loan Bank (FHLB) borrowings, which were largely short term. On May 1, 2023, Business First redeemed an $8.9 million tranche of outstanding subordinated debt, of which $5.7 million was extinguished as of June 30, 2023. This resulted in a $941,000 gain on extinguishment of debt.

Shareholders’ Equity

Accumulated other comprehensive income (AOCI) decreased $13.3 million due to negative after-tax fair value changes in the securities portfolio. Book value per common share nonetheless still increased to $20.87 at June 30, 2023, compared to $20.77 at March 31, 2023, due to strong second quarter earnings. On a non-GAAP basis, tangible book value per common share increased to $16.87 at June 30, 2023, compared to $16.73 at March 31, 2023.

Results of Operations

Net Interest Income

For the quarter ended June 30, 2023, net interest income totaled $53.3 million, compared to $52.7 million from the linked quarter. Loan and interest-earning asset yields of 6.54% and 5.84%, respectively, increased 20 basis points and 19 basis points, respectively, compared to 6.34% and 5.65% from the linked quarter. The increases were largely attributable to loan repricing and higher yields on new originations. Net interest margin and net interest spread were 3.63% and 2.75%, respectively, compared to 3.75% and 2.96%, respectively, for the linked quarter. Interest income for the quarter ended March 31, 2023, included $853,000 of additional loan discount accretion due to a large, acquired loan payoff and accelerated accretion from the purchased impaired portfolio. Overall cost of funds, which include noninterest-bearing deposits, increased from 1.97% to 2.31% or 34 basis points, from the linked quarter due largely to higher cost deposits.

Non-GAAP net interest income (excluding loan discount accretion of $2.1 million) totaled $51.3 million for the quarter ended June 30, 2023, compared to $49.8 million (excluding loan discount accretion of $2.9 million) from the linked quarter. Non-GAAP net interest margin and net interest spread (excluding loan discount accretion of $2.1 million) were 3.49% and 2.51%, respectively, for the quarter ended June 30, 2023, compared to 3.54% and 2.75% (excluding loan discount accretion of $2.9 million) for the linked quarter. Excluding loan discount accretion, loan yields increased 28 basis points from 6.09% to 6.37% and interest earnings asset yields increased 36 basis points from 5.44% to 5.70%, compared to the linked quarter.

Provision for Credit Losses

During the quarter ended June 30, 2023, Business First recorded a provision for credit losses of $538,000, compared to $3.2 million for the linked quarter. The current quarter reserve was impacted by loan growth in loan portfolios with lower estimated loss rates and lower reserves for unfunded commitments due to lower unfunded balances. The provision for credit losses for the quarter ended March 31, 2023, included the resolution of an acquired impaired lending relationship in March 2023, which resulted in a charge-off of $1.9 million.

Other Income

For the quarter ended June 30, 2023, other income increased $3.6 million or 42.56%, compared to the linked quarter. The net increase was largely attributable to a $2.6 million increase in equity investment income and a $941,000 gain on extinguishment of debt.

Other Expenses

For the quarter ended June 30, 2023, other expenses increased by $1.0 million, or 2.65%, compared to the linked quarter. The net increase was largely attributable to a $1.6 million increase in data processing charges, offset by a reduction of $837,000 in salary and employee benefits. The increase in data processing costs was partially attributable to $453,000 of rebates received during the first quarter and $715,000 in charges paid in the second quarter attributed to an error identified by our data processor in their billing system.

Return on Assets and Common Equity

Return to common shareholders on average assets and common equity, each on an annualized basis, were 1.18% and 13.99%, respectively, for the quarter ended June 30, 2023, compared to 0.91% and 10.73%, respectively, for the linked quarter. Non-GAAP return to common shareholders on average assets and common equity, each on an annualized basis, were 1.13% and 13.50%, respectively, for the quarter ended June 30, 2022, compared to 0.91% and 10.81%, respectively, for the linked quarter.

Non-GAAP Financial Measures

This press release includes certain non-GAAP financial measures (e.g., referenced as “core” or “tangible”) intended to supplement, not substitute for, comparable GAAP measures. “Core” measures typically adjust income available to common shareholders for certain significant activities or transactions that, in management’s opinion, can distort period-to-period comparisons of Business First’s performance. Transactions that are typically excluded from non-GAAP “core” measures include realized and unrealized gains/losses on former bank premises and equipment, investment sales, acquisition-related expenses (including, but not limited to, legal costs, system conversion costs, severance and retention payments, etc.). “Tangible” measures adjust common equity by subtracting goodwill, core deposit intangibles, and customer intangibles, net of accumulated amortization. Management believes presentations of these non-GAAP financial measures provide useful supplemental information that is essential to a proper understanding of the operating results of Business First’s core business. These non-GAAP disclosures are not necessarily comparable to non-GAAP measures that may be presented by other companies. Reconciliations of non-GAAP financial measures to GAAP financial measures are provided at the end of the tables below.
