For Immediate Release

Investar Holding Corporation Announces 2023 Third Quarter Results 

BATON ROUGE, LA / ACCESSWIRE / October 19, 2023 / Investar Holding Corporation (“Investar”) (NASDAQ:ISTR), the holding company for Investar Bank, National Association (the “Bank”), today announced financial results for the quarter ended September 30, 2023. Investar reported net income of $2.8 million, or $0.28 per diluted common share, for the third quarter of 2023, compared to net income of $6.5 million, or $0.67 per diluted common share, for the quarter ended June 30, 2023, and net income of $7.3 million, or $0.73 per diluted common share, for the quarter ended September 30, 2022.

On a non-GAAP basis, core earnings per diluted common share for the third quarter of 2023 were $0.33 compared to $0.67 for the second quarter of 2023 and $0.71 for the third quarter of 2022. Core earnings exclude certain items including, but not limited to, loss on sale or disposition of fixed assets, net, severance and loan purchase expense (refer to the Reconciliation of Non-GAAP Financial Measures tables for a reconciliation of GAAP to non-GAAP metrics).

Strong Credit Quality

Investar has increased its focus on underwriting high quality credits that are less susceptible to effects from a potential economic downturn and continues to de-risk the portfolio by proactively exiting credit relationships that do not fit this strategy. As a result, credit quality has continued to improve as nonperforming loans were only $5.6 million, or 0.27% of total loans at September 30, 2023 compared to $7.0 million, or 0.34%, at June 30, 2023. 

Loan Purchase Agreement

Investar entered into a loan purchase agreement to acquire commercial and industrial revolving lines of credit with an unpaid principal balance of approximately $163 million in two tranches. The purchase of the first tranche, consisting of revolving lines of credit with an unpaid principal balance of approximately $36 million, was completed in the third quarter. The purchase of the second tranche, consisting of revolving lines of credit with an unpaid principal balance of approximately $127 million, closed in the fourth quarter. The revolving lines of credit are variable-rate and short-term in nature with varying renewal terms. 

Exit of Consumer Mortgage Origination Business

In an effort to focus more on its core business and optimize profitability, Investar made the strategic decision to exit its consumer mortgage origination business. Investar will retain and continue to service the existing consumer mortgage loan portfolio. Consumer mortgage loan products are generally long-term and fixed-rate and generally require a higher relative allowance for credit losses than other loan products. Consumer mortgage volumes have decreased to historical lows due to the combination of rising housing prices and interest rates and constriction of housing supply. As a result of this decision, Investar further optimized its workforce and will continue to dedicate resources to its more profitable business lines. The consumer mortgage portfolio was approximately $264.1 million at September 30, 2023 and is included in the 1-4 family loan category.

Investar’s President and Chief Executive Officer John D’Angelo commented: 

Finally, we continue to execute on the evaluation and optimization of our physical branch and ATM footprint. As a result of our ongoing review, we ceased operation of 14 ATMs which will result in future cost savings while maintaining uninterrupted service to our valued customers. 

As always, we remain focused on shareholder value and returning capital to shareholders. We repurchased 52,407 shares of our common stock during the third quarter well below tangible book value at an average price of $12.89 per share.

Third Quarter Highlights

Loans

Total loans were $2.10 billion at September 30, 2023, an increase of $18.2 million, or 0.9%, compared to June 30, 2023, and an increase of $97.3 million, or 4.9%, compared to September 30, 2022.

The following table sets forth the composition of the total loan portfolio as of the dates indicated (dollars in thousands).

Nonowner-occupied loans totaled $501.6 million at September 30, 2023, a decrease of $29.2 million, or 5.5%, compared to $530.8 million at June 30, 2023, and an increase of $37.1 million, or 8.0%, compared to $464.5 million at September 30, 2022. The decrease in nonowner-occupied loans compared to June 30, 2023 is primarily due to a reclassification of approximately $24.1 million nonowner-occupied loans to multifamily loans due to a change to the primary use of the property. The increase in nonowner-occupied loans compared to September 30, 2022 is due to organic growth.

Credit Quality

Nonperforming loans were $5.6 million, or 0.27% of total loans, at September 30, 2023, a decrease of $1.4 million compared to $7.0 million, or 0.34% of total loans, at June 30, 2023, and a decrease of $7.5 million compared to $13.1 million, or 0.65% of total loans, at September 30, 2022. The decrease in nonperforming loans compared to June 30, 2023 is mainly attributable to paydowns. Included in nonperforming loans are acquired loans with a balance of $1.9 million at September 30, 2023, or 35% of nonperforming loans.

On January 1, 2023, Investar adopted FASB ASC Topic 326 “Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments” Update No. 2016-13. The ASU, referred to as the Current Expected Credit Loss (“CECL”) standard, requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Upon adoption, Investar recorded a one-time, cumulative effect adjustment to increase the allowance for credit losses by $5.9 million and reduce retained earnings, net of tax, by $4.3 million.

The allowance for credit losses was $29.8 million, or 534.1% and 1.42% of nonperforming and total loans, respectively, at September 30, 2023, compared to $30.0 million, or 429.6% and 1.44% of nonperforming and total loans, respectively, at June 30, 2023, and $23.2 million, or 176.6% and 1.15% of nonperforming and total loans, respectively, at September 30, 2022. 

Investar recorded a negative provision for credit losses of $34,000 for the quarter ended September 30, 2023 compared to a negative provision for credit losses of $2.8 million and a provision for credit losses of $1.2 million for the quarters ended June 30, 2023 and September 30, 2022, respectively. The negative provision for credit losses in the quarter ended September 30, 2023 was primarily due to net recoveries. The negative provision for credit losses in the quarter ended June 30, 2023 was driven by net recoveries of $2.4 million, primarily attributable to recoveries on one loan relationship that became impaired in the third quarter of 2021 as a result of Hurricane Ida. The provision for credit losses for the quarter ended September 30, 2022 was due to organic loan growth.

Deposits

Total deposits at September 30, 2023 were $2.21 billion, an increase of $28.6 million, or 1.3%, compared to $2.18 billion at June 30, 2023, and an increase of $156.8 million, or 7.6%, compared to $2.05 billion at September 30, 2022. 

The following table sets forth the composition of deposits as of the dates indicated (dollars in thousands).

The increase in money market deposit accounts at September 30, 2023 compared to June 30, 2023 is primarily due to higher rates offered. The decrease in money market deposit accounts at September 30, 2023 compared to September 30, 2022 is primarily due to customers shifting into higher yielding interest-bearing deposit products as a result of rising interest rates. The increase in time deposits at September 30, 2023 compared to June 30, 2023 is primarily due to existing customer funds migrating from other deposit categories. The increase in time deposits at September 30, 2023 compared to September 30, 2022 is primarily due to organic growth and existing customer funds migrating from other deposit categories. Noninterest-bearing demand deposits and interest-bearing demand deposits decreased over the periods due to shifts by customers into higher yielding interest-bearing deposit products as a result of rising interest rates. Brokered time deposits increased to $197.7 million at September 30, 2023 from $153.4 million at June 30, 2023. Investar utilizes brokered time deposits, entirely in denominations of less than $250,000, to secure fixed cost funding and reduce short-term borrowings. At September 30, 2023, the balance of brokered time deposits remained below 10% of total assets, and the remaining weighted average duration is approximately 13 months with a weighted average rate of 5.02%. 

Stockholders’ Equity 

Stockholders’ equity was $208.7 million at September 30, 2023, a decrease of $9.6 million compared to June 30, 2023, and an increase of $3.0 million compared to September 30, 2022. The decrease in stockholders’ equity compared to June 30, 2023 is primarily attributable to an increase in accumulated other comprehensive loss due to a decrease in the fair value of the Bank’s available for sale securities portfolio, partially offset by net income for the quarter. The increase in stockholders’ equity compared to September 30, 2022 is primarily attributable to net income for the last twelve months, partially offset by an increase in accumulated other comprehensive loss due to a decrease in the fair value of the Bank’s available for sale securities portfolio and the cumulative effect adjustment as a result of the adoption of the CECL standard, reflected in retained earnings.

Net Interest Income

Net interest income for the third quarter of 2023 totaled $17.5 million, a decrease of $0.9 million, or 5.0%, compared to the second quarter of 2023, and a decrease of $6.0 million, or 25.6%, compared to the third quarter of 2022. Total interest income was $33.2 million, $32.4 million and $27.0 million for the quarters ended September 30, 2023, June 30, 2023 and September 30, 2022, respectively. Total interest expense was $15.7 million, $14.0 million and $3.5 million for the corresponding periods. Included in net interest income for the quarters ended September 30, 2023, June 30, 2023 and September 30, 2022 is $36,000, $47,000, and $0.1 million, respectively, of interest income accretion from the acquisition of loans. Also included in net interest income for each of the quarters ended September 30, 2023 and September 30, 2022 are interest recoveries of $0.1 million. There were no interest recoveries for the quarter ended June 30, 2023.

Investar’s net interest margin was 2.66% for the quarter ended September 30, 2023, compared to 2.82% for the quarter ended June 30, 2023 and 3.77% for the quarter ended September 30, 2022. The decrease in net interest margin for the quarter ended September 30, 2023 compared to the quarter ended June 30, 2023 was driven by a 28 basis point increase in the overall cost of funds, partially offset by a seven basis point increase in the yield on interest-earning assets. The decrease in net interest margin for the quarter ended September 30, 2023 compared to the quarter ended September 30, 2022 was driven by a 228 basis point increase in the overall cost of funds, partially offset by a 71 basis point increase in the yield on interest-earning assets.

The yield on interest-earning assets was 5.05% for the quarter ended September 30, 2023, compared to 4.98% for the quarter ended June 30, 2023 and 4.34% for the quarter ended September 30, 2022. The increase in the yield on interest-earning assets compared to the quarter ended June 30, 2023 was primarily attributable to a nine basis point increase in the yield on the loan portfolio, partially offset by a 10 basis point decrease in the yield on the taxable securities portfolio. The increase in the yield on interest-earning assets compared to the quarter ended September 30, 2022 was primarily driven by a 67 basis point increase in the yield on the loan portfolio and a 38 basis point increase in the yield on the taxable securities portfolio.

Exclusive of the interest income accretion from the acquisition of loans, interest recoveries, and accelerated fee income recognized due to the forgiveness or pay-off of Paycheck Protection Program (“PPP”) loans, adjusted net interest margin decreased to 2.64% for the quarter ended September 30, 2023, compared to 2.82% for the quarter ended June 30, 2023, and 3.72% for the quarter ended September 30, 2022. The adjusted yield on interest-earning assets was 5.03% for the quarter ended September 30, 2023 compared to 4.97% and 4.29% for the quarters ended June 30, 2023 and September 30, 2022, respectively. Refer to the Reconciliation of Non-GAAP Financial Measures table for a reconciliation of GAAP to non-GAAP metrics.

The cost of deposits increased 42 basis points to 2.73% for the quarter ended September 30, 2023 compared to 2.31% for the quarter ended June 30, 2023 and increased 237 basis points compared to 0.36% for the quarter ended September 30, 2022. The increase in the cost of deposits compared to the quarter ended June 30, 2023 resulted from both a higher average balance and an increase in rates paid on time deposits, a higher average balance of brokered time deposits, and an increase in rates paid on interest-bearing demand deposits and savings deposits. The increase in the cost of deposits compared to the quarter ended September 30, 2022 resulted from both a higher average balance and an increase in rates paid on time deposits, a higher average balance of brokered time deposits, and an increase in rates paid on interest-bearing demand deposits, partially offset by a lower average balance of interest-bearing demand deposits. 

The cost of short-term borrowings decreased 12 basis points to 4.97% for the quarter ended September 30, 2023 compared to 5.09% for the quarter ended June 30, 2023 and increased 257 basis points compared to 2.40% for the quarter ended September 30, 2022. Beginning in the second quarter of 2023, the Bank began utilizing the Federal Reserve’s Bank Term Funding Program (“BTFP”) to secure fixed rate funding for up to a one-year term and reduce short-term Federal Home Loan Bank (“FHLB”) advances, which are priced daily. The Bank utilized this source of funding due to its lower rate as compared to FHLB advances, the ability to prepay the obligations without penalty, and as a means to lock in funding. The decrease in the cost of short-term borrowings compared to the quarter ended June 30, 2023 resulted primarily from the reduction of short-term advances from the FHLB and the increased utilization of short-term repurchase agreements. The increase in the cost of short-term borrowings compared to the quarter ended September 30, 2022 resulted from an increase in the Federal Reserve’s federal funds rate, which drives the costs of short-term borrowings under the BTFP and short-term advances from the FHLB. 

The overall cost of funds for the quarter ended September 30, 2023 increased 28 basis points to 3.07% compared to 2.79% for the quarter ended June 30, 2023 and increased 228 basis points compared to 0.79% for the quarter ended September 30, 2022. The increase in the cost of funds for the quarter ended September 30, 2023 compared to the quarter ended June 30, 2023 resulted from both a higher average balance and an increase in the cost of deposits, partially offset by both a lower average balance and a decrease in the cost of short-term borrowings. The increase in the cost of funds for the quarter ended September 30, 2023 compared to the quarter ended September 30, 2022 resulted from both a higher average balance and an increase in the cost of deposits and both a higher average balance and an increase in the cost of short-term borrowings.

Noninterest Income

Noninterest income for the third quarter of 2023 totaled $1.6 million, a decrease of $0.4 million, or 20.9%, compared to the second quarter of 2023 and a decrease of $1.0 million, or 38.6%, compared to the third quarter of 2022.

The decrease in noninterest income compared to the quarter ended June 30, 2023 is driven by a $0.3 million increase in loss on sale or disposition of fixed assets and a $0.3 million decrease in other operating income, partially offset by a $0.1 million increase in the change in fair value of equity securities and a $0.1 million increase in service charges on deposit accounts. The decrease in other operating income is primarily attributable to a $0.2 million decrease in the change in the net asset value of other investments and a $0.1 million decrease in distributions from investments. 

The decrease in noninterest income compared to the quarter ended September 30, 2022 is mainly attributable to a $0.3 million increase in loss on sale or disposition of fixed assets and a $0.7 million decrease in other operating income. The decrease in other operating income is primarily attributable to a $0.4 million decrease in the change in the net asset value of other investments and a $0.3 million decrease in derivative fee income. 

Noninterest Expense

Noninterest expense for the third quarter of 2023 totaled $15.8 million, an increase of $0.5 million, or 3.5%, compared to the second quarter of 2023, and a decrease of $0.2 million, or 1.2%, compared to the third quarter of 2022. 

The increase in noninterest expense for the quarter ended September 30, 2023 compared to the quarter ended June 30, 2023 was primarily driven by a $0.1 million increase in salaries and employee benefits, a $0.2 million increase in professional fees, and a $0.2 million increase in other operating expenses. The increase in salaries and employee benefits is primarily due to severance related to Investar’s exit from its consumer mortgage origination business. Other operating expenses include, among other things, software expense, other real estate expense, FDIC assessments, bank security, and bank shares tax.

The decrease in noninterest expense for the quarter ended September 30, 2023 compared to the quarter ended September 30, 2022 is primarily a result of a $0.2 million decrease in depreciation and amortization and a $0.2 million decrease in occupancy, partially offset by a $0.1 million increase in salaries and employee benefits. The decreases in depreciation and amortization and occupancy are due to the sale of the Alice and Victoria, Texas branches in January 2023 and the closure of one branch location in the first quarter of 2023. The increase in salaries and employee benefits is primarily due to severance related to Investar’s exit from its consumer mortgage origination business.

Taxes

Investar recorded an income tax expense of $0.6 million for the quarter ended September 30, 2023, which equates to an effective tax rate of 17.4%, compared to effective tax rates of 18.7% and 18.9% for the quarters ended June 30, 2023 and September 30, 2022, respectively.

Basic and Diluted Earnings Per Common Share

Investar reported basic and diluted earnings per common share of $0.28 for the quarter ended September 30, 2023, compared to basic and diluted earnings per common share of $0.67 for the quarter ended June 30, 2023, and basic and diluted earnings per common share of $0.74 and $0.73, respectively, for the quarter ended September 30, 2022.
