INDEPENDENT BANK GROUP, INC. REPORTS SECOND QUARTER FINANCIAL RESULTS AND DECLARES QUARTERLY DIVIDEND

July 24, 2024

McKINNEY, Texas, July 24, 2024 -- Independent Bank Group, Inc. (NASDAQ: IBTX) today announced net loss of $493.5 million, or $11.89 per diluted share, for the quarter ended June 30, 2024, which was significantly impacted by $518.0 million of goodwill impairment recognized as a result of the Company's stock price trading below book value and the announced merger with SouthState Corporation. Goodwill impairment is a non-cash charge and has no impact on cash flows, liquidity, (non-GAAP) tangible equity, or regulatory capital. Excluding the goodwill impairment charge and other non-recurring items, adjusted (non-GAAP) net income for the quarter ended June 30, 2024 was $24.9 million, or $0.60 per diluted share.

The Company also announced that its Board of Directors declared a quarterly cash dividend of $0.38 per share of common stock. The dividend will be payable on August 19, 2024 to stockholders of record as of the close of business on August 5, 2024.

Highlights

•Pending acquisition by SouthState Corporation announced on May 20, 2024

•Net interest margin expanded by 5 basis points to 2.47% compared to 2.42% in linked quarter

•Loan yields expanded by 10 basis points to 6.03%

•Continued healthy credit metrics with nonperforming asset ratio of 0.35% and last twelve months' net charge-off to average total loans ratio of 0.03%

•Total capital ratio grew by 7 basis points to 11.75%, and (non-GAAP) tangible common equity (TCE) ratio grew by 10 basis points to 7.72%

"During the quarter, we were pleased to see the anticipated expansion of our net interest margin as increases in loan yields began to outpace deposit cost pressures. We are encouraged by strong economic tailwinds across Texas and Colorado. Importantly, our loan portfolio remains bolstered by resilient credit quality across product types," said Independent Bank Group Chairman & CEO David R. Brooks. "We look forward to remaining disciplined and focused on the execution of all our key strategic initiatives as we work toward the completion of our pending merger with SouthState Corporation. We are very excited to join SouthState, a company whose culture, business model, and credit discipline matches ours."

Second Quarter 2024 Balance Sheet Highlights

Loans

•Total loans held for investment, excluding mortgage warehouse purchase loans, were $14.0 billion at June 30, 2024 compared to $14.1 billion at March 31, 2024 and $13.6 billion at June 30, 2023. Loans held for investment, excluding mortgage warehouse purchase loans, decreased $72.1 million, or 2.1% on an annualized basis, during second quarter 2024.

•Average mortgage warehouse purchase loans were $538.5 million for the quarter ended June 30, 2024 compared to $455.7 million for the quarter ended March 31, 2024, and $413.2 million for the quarter ended June 30, 2023, an increase of $82.8 million, or 18.2% from the linked quarter and an increase of $125.3 million, or 30.3% year over year.

Asset Quality

•Nonperforming assets totaled $64.9 million, or 0.35% of total assets at June 30, 2024, compared to $65.1 million or 0.34% of total assets at March 31, 2024, and $60.5 million, or 0.32% of total assets at June 30, 2023.

•Nonperforming loans totaled $56.1 million, or 0.40% of total loans held for investment at June 30, 2024, compared to $56.3 million, or 0.40% at March 31, 2024 and $37.9 million, or 0.28% at June 30, 2023.

•The decrease in nonperforming loans for the linked quarter was primarily due to $906 thousand in charge-offs on one commercial relationship offset by individually insignificant net additions of nonperforming loans. The year over year period reflects $18.2 million in net additions primarily related to a $13.0 million commercial real estate loan added to nonaccrual in fourth quarter 2023 and a $2.0 million commercial relationship added in first quarter 2024.

•The changes in nonperforming assets for the linked quarter and prior year reflects the nonperforming loan changes discussed above. In addition, the prior year change also includes reductions of $13.8 million in other real estate owned.

•Net charge-offs were 0.10% annualized in the second quarter 2024 compared to 0.00% annualized in the linked quarter and (0.03)% annualized in the prior year quarter. The elevated level of charge-offs in second quarter 2024 was due primarily to the commercial relationship mentioned above as well as charge-offs totaling $2.6 million related to a single-family construction relationship.

Deposits, Borrowings and Liquidity

•Total deposits were $15.8 billion at June 30, 2024 compared to $15.7 billion at March 31, 2024 and $14.9 billion at June 30, 2023.

•Total borrowings (other than junior subordinated debentures) were $427.1 million at June 30, 2024, a decrease of $69.8 million from March 31, 2024 and a decrease of $753.1 million from June 30, 2023. The linked quarter change reflects the payoff of a $70.0 million BTFP advance. The year over year change primarily reflects reductions of $875.0 million in short-term FHLB advances and $33.8 million in line of credit borrowings, offset by a $155.0 million BTFP advance taken in first quarter 2024.

Capital

•The Company continues to be well capitalized under regulatory guidelines. At June 30, 2024, the estimated common equity Tier 1 to risk-weighted assets, Tier 1 capital to average assets, Tier 1 capital to risk-weighted assets and total capital to risk-weighted asset ratios were 9.69%, 8.76%, 10.03% and 11.75%, respectively, compared to 9.60%, 8.91%, 9.94%, and 11.68%, respectively, at March 31, 2024 and 9.78%, 8.92%, 10.13%, and 11.95%, respectively at June 30, 2023.

Second Quarter 2024 Operating Results

Net Interest Income

•Net interest income was $105.1 million for second quarter 2024 compared to $113.6 million for second quarter 2023 and $103.0 million for first quarter 2024. The decrease from the prior year was primarily due to the increased funding costs on our deposit products, including brokered deposits due to the interest rate environment over the period offset to a lesser extent by increased earnings on average loan balances. The increase from the linked quarter was primarily due to increased earnings on loans offset to a lesser extent by increased deposit funding costs for the quarter. The second quarter 2024 includes $1.0 million in acquired loan accretion compared to $870 thousand in second quarter 2023 and $753 thousand in first quarter 2024.

•The average balance of total interest-earning assets grew by $298.6 million and totaled $17.1 billion for the quarter ended June 30, 2024 compared to $16.8 billion for the quarter ended June 30, 2023 and decreased minimally by $9.9 million from $17.1 billion for the quarter ended March 31, 2024. The increase from the prior year is primarily due to an increase in average loans of $608.0 million due to organic growth primarily occurring in the second half of 2023 offset by decreases in average securities and interest-bearing cash balances.

•The yield on interest-earning assets was 5.62% for second quarter 2024 compared to 5.14% for second quarter 2023 and 5.53% for first quarter 2024. The increase in asset yield compared to the prior year and linked quarter is primarily a result of increases in the benchmark rates over the last year. The average loan yield, net of acquired loan accretion was 6.00% for the current quarter, compared to 5.51% for prior year quarter and 5.91% for the linked quarter.

•The cost of interest-bearing liabilities, including borrowings, was 4.16% for second quarter 2024 compared to 3.37% for second quarter 2023 and 4.11% for first quarter 2024. The increase from the prior year is reflective of higher funding costs, primarily on deposit products as a result of Fed Funds rate increases in 2023 offset by decreased costs on FHLB advances, primarily due to lower holdings based on liquidity needs resulting in a shift in funding sources during the year-over-year period. The linked quarter change also reflects a slight increase in funding costs on deposits. Both period funding costs were negatively impacted by the shift from non-interest bearing deposits into interest-bearing products as well as an increase in higher cost brokered deposits for the respective periods.

•The net interest margin was 2.47% for second quarter 2024 compared to 2.71% for second quarter 2023 and 2.42% for first quarter 2024. The net interest margin excluding acquired loan accretion was 2.45% for second quarter 2024 compared to 2.69% for second quarter 2023 and 2.40% for first quarter 2024. The decrease in net interest margin from the prior year was primarily due to the increased funding costs on deposits, offset by a reduction in funding costs on FHLB advances and higher earnings on loans due to organic growth and rate increases for the respective periods. The linked quarter change positively reflects the increased rates earned on fixed rate loans, which have reset at a faster pace than the offsetting increase in deposit funding costs for the quarter.

Noninterest Income

•Total noninterest income decreased $662 thousand compared to second quarter 2023 and increased $563 thousand compared to first quarter 2024.

•The decrease from the prior year quarter primarily reflects a $708 thousand decrease in mortgage banking revenue due to lower volumes resulting from rate increases for the year over year period.

•The increase from the linked quarter primarily reflects a $469 thousand increase in other noninterest income, comprised of net increases in various miscellaneous income streams.

Noninterest Expense

•Total noninterest expense increased $521.2 million compared to second quarter 2023 and increased $518.4 million compared to first quarter 2024. Adjusted noninterest expense (non-GAAP) increased $2.7 million compared to second quarter 2023 and $1.2 million compared to first quarter 2024. As previously explained, a goodwill impairment charge of $518.0 million was recognized in second quarter 2024, in addition to $2.3 million in merger-related expenses and a $645 thousand credit true-up to the additional FDIC special assessment accrued in first quarter 2024.

•As a result of entering into a merger agreement with SouthState Corporation along with continued stock price volatility in the banking sector during the quarter, the Company determined such events triggered an interim goodwill assessment. As required by GAAP, the Company recorded impairment to goodwill as its estimated fair value of equity, which is equal to the implied valuation of the merger transaction based upon the conversion ratio to SouthState's stock price, was less than book value as of June 30, 2024.

3

•The increase in adjusted noninterest expense (non-GAAP) in second quarter 2024 compared to the prior year is due primarily to increases of $2.1 million in salaries and benefits and $620 thousand in other noninterest expense offset by a $484 thousand decrease in professional fees.

•The increase from the linked quarter primarily reflects increases of $1.7 million in salaries and benefits expense and $820 thousand in other noninterest expense offset by decreases of $586 thousand in FDIC assessment, as adjusted, and $508 thousand in professional fees.

•The increase in salaries and benefits from the prior year is due primarily to $2.9 million higher combined salaries and bonus expenses compared to the prior year quarter offset by $386 thousand in lower contract labor costs and $670 thousand in lower employee insurance expenses. The linked quarter change reflects higher salaries, bonus and stock amortization expenses of $3.1 million due to a full quarter of salary increases and equity compensation expenses granted as part of the merit process that occurred in mid first quarter, offset by $859 thousand in lower employee insurance costs and $491 thousand lower payroll taxes, which are seasonably higher in the first quarter.

•The decrease in professional fees from the prior year and linked quarter was primarily due to lower consulting fees due to less active projects and lower audit and tax-related expenses.

•The increase in other noninterest expense from the prior year and linked quarter was primarily due to operational losses related to increased check and debit card fraud. The decrease in adjusted FDIC assessment compared to the linked quarter was due to improvements in the quarterly assessment's liquidity stress rates.

Provision for Credit Losses

•The Company recorded zero provision for credit losses for second quarter 2024, compared to provision expense of $220 thousand for second quarter 2023 and provision reversal of $3.2 million for the linked quarter. Provision expense (reversal) during a given period is generally dependent on changes in various factors, including economic conditions, credit quality and past due trends, as well as loan growth or decline and charge-offs or specific credit loss allocations taken during the respective period.

•The allowance for credit losses on loans was $145.3 million, or 1.04% of total loans held for investment, net of mortgage warehouse purchase loans, at June 30, 2024, compared to $147.8 million, or 1.08% at June 30, 2023 and compared to $148.4 million, or 1.06% at March 31, 2024.

•The allowance for credit losses on off-balance sheet exposures was $3.5 million at June 30, 2024 compared to $4.9 million at June 30, 2023, compared to $4.1 million at March 31, 2024. Changes in the allowance for unfunded commitments are generally driven by the remaining unfunded amount and the expected utilization rate of a given loan segment.

Income Taxes

•Federal income tax expense of $5.1 million was recorded for the second quarter 2024, an effective rate of (1.0)% compared to federal tax expense of $8.7 million and an effective rate of 20.8% for the prior year quarter and income tax expense of $6.5 million and an effective rate of 21.2% for the linked quarter. The decrease in the effective tax rate from the linked quarter was predominately due to the goodwill impairment charge, of which $512.4 million is not deductible for tax purposes. Excluding the goodwill impairment and other non-deductible expenses, the estimated tax rate for the second quarter is 20.5%.

As a result of these and other matters, including changes in facts, assumptions not being realized or other factors, the actual results relating to the subject matter of any forward-looking statement may differ materially from the anticipated results expressed or implied in that forward-looking statement.

looking statement, whether as a result of new information, future developments or otherwise, except as may be required by law. A forward-looking statement may include a statement of the assumptions or bases underlying the forward-looking statement. The Company believes that these assumptions or bases have been chosen in good faith and that they are reasonable. However, the Company cautions you that assumptions as to future occurrences or results almost always vary from actual future occurrences or results, and the differences between assumptions and actual occurrences and results can be material. Therefore, the Company cautions you not to place undue reliance on the forward-looking statements contained in this filing or incorporated by reference herein.

Non-GAAP Financial Measures

In addition to results presented in accordance with GAAP, this press release contains certain non-GAAP financial measures. These measures and ratios include "adjusted net income," "adjusted earnings," "tangible book value," "tangible book value per common share," "adjusted efficiency ratio," "tangible common equity to tangible assets," "adjusted net interest margin," "return on tangible equity," "adjusted return on average assets" and "adjusted return on average equity" and are supplemental measures that are not required by, or are not presented in accordance with, accounting principles generally accepted in the United States. We consider the use of select non-GAAP financial measures and ratios to be useful for financial operational decision making and useful in evaluating period-to-period comparisons. We believe that these non-GAAP financial measures provide meaningful supplemental information regarding our performance by excluding certain expenditures or assets that we believe are not indicative of our primary business operating results. We believe that management and investors benefit from referring to these non-GAAP financial measures in assessing our performance and when planning, forecasting, analyzing and comparing past, present and future periods.

We believe that these measures provide useful information to management and investors that is supplementary to our financial condition, results of operations and cash flows computed in accordance with GAAP; however we acknowledge that our financial measures have a number of limitations relative to GAAP financial measures. Certain non-GAAP financial measures exclude items of income, expenditures, expenses, assets, or liabilities, including provisions for credit losses and the effect of goodwill, other intangible assets and income from accretion on acquired loans arising from purchase accounting adjustments, that we believe cause certain aspects of our results of operations or financial condition to be not indicative of our primary operating results. All of these items significantly impact our financial statements. Additionally, the items that we exclude in our adjustments are not necessarily consistent with the items that our peers may exclude from their results of operations and key financial measures and therefore may limit the comparability of similarly named financial measures and ratios. We compensate for these limitations by providing the equivalent GAAP measures whenever we present the non-GAAP financial measures and by including a reconciliation of the impact of the components adjusted for in the non-GAAP financial measure so that both measures and the individual components may be considered when analyzing our performance.

A reconciliation of our non-GAAP financial measures to the comparable GAAP financial measures is included at the end of the financial statements tables.
