Third Quarter 2021 Operating Results

Net Interest Income

Net interest income was $128.6 million for third quarter 2021 compared to $132.0 million for third quarter 2020 and $129.3 million for second quarter 2021. The decrease in net interest income from the prior year was driven by decreased earnings on assets due to lower yields and accretion, offset by overall decreased funding costs for the year over year period. The slight decrease from the linked quarter was due primarily to a shift in interest-earning assets from loans to securities and interest-bearing balances as well as lower overall yields and lower accretion, offset by a decrease in interest expense due to lower rates paid on deposit accounts and the payoff of $40 million in subordinated debentures in third quarter 2021. The third quarter 2021 includes $4.0 million in acquired loan accretion compared to $5.2 million in second quarter 2021 and $7.2 million in third quarter 2020. In addition, we recognized net PPP fees of $4.0 million in third quarter 2021 compared to $5.1 million in second quarter 2021 and $4.6 million in third quarter 2020 with total fees left to be recognized of $6.5 million as of September 30, 2021.
The average balance of total interest-earning assets grew by $2.0 billion and totaled $17.0 billion for the quarter ended September 30, 2021 compared to $14.9 billion for the quarter ended September 30, 2020 and increased $471.9 million from $16.5 billion for the quarter ended June 30, 2021. The increase for both periods is primarily due to the continued growth of average interest bearing cash balances over the past year, increasing $1.7 billion from prior year and $356.4 million from the linked quarter and also due to continued increases in average taxable securities. Offsetting these changes is a net decrease in average loan balances, due primarily to the forgiveness of Paycheck Protection Program (PPP) loans. Average PPP loans, net of fees decreased to $368.3 million in third quarter 2021, from $701.8 million in second quarter 2021 and $808.9 million in third quarter 2020.
The yield on interest-earning assets was 3.37% for third quarter 2021 compared to 4.04% for third quarter 2020 and 3.54% for second quarter 2021. The overall asset yield is down for both periods due to the continued increase in lower-yielding interest bearing cash balances mentioned above as well as lower loans and securities yields for the year over year period. The average loan yield, net of all accretion decreased six basis points from the linked quarter compared to a 14 basis point decrease from the prior year.
The cost of interest-bearing liabilities, including borrowings, was 0.54% for third quarter 2021 compared to 0.77% for third quarter 2020 and 0.60% for second quarter 2021. The decrease from the prior year and linked quarter is primarily due to lower rates offered on our deposit products as well as rate decreases on other borrowings and trust preferred securities.
The net interest margin was 3.01% for third quarter 2021 compared to 3.52% for third quarter 2020 and 3.14% for second quarter 2021. The net interest margin excluding all loan accretion was 2.91% for third quarter 2021 compared to 3.32% in third quarter 2020 and 3.02% for second quarter 2021. The decrease in net interest margin from the prior year was primarily due to the lower asset yields, increased liquidity and a decrease of $3.2 million in loan accretion income, offset by the lower cost of funds on interest bearing liabilities. The 11 basis point decrease in the net interest margin excluding all loan accretion from the linked quarter is primarily a result of excess liquidity which negatively impacted the margin by seven (7) basis points but also due to lower loan and securities yields, offset by slightly lower cost of funds of interest bearing liabilities for the quarter.

Noninterest Income

Total noninterest income decreased $8.3 million compared to third quarter 2020 and increased $970 thousand compared to second quarter 2021.
The decrease from the prior year primarily reflects a decrease of $8.7 million in mortgage banking revenue while the linked quarter change reflects an increase of $745 thousand in mortgage banking revenue.
Mortgage banking revenue was lower in third quarter 2021 compared to prior year due to decreased volumes and margins resulting from rate increases in 2021. It was also impacted by continued volatility in the market during the quarter, which resulted in fair value losses on our derivative hedging instruments of $1.0 million compared to third quarter 2020 gain of $982 thousand and $700 thousand loss for second quarter 2021.

Noninterest Expense

Total noninterest expense increased $7.2 million compared to third quarter 2020 and increased $2.6 million compared to second quarter 2021.
The net increase in noninterest expense compared to third quarter 2020 is due primarily to increases of $4.3 million in salaries and benefits expenses, $1.7 million in professional fees and $1.5 million in other noninterest expense.
The increase from the linked quarter is primarily due to an increase of $2.7 million in salaries and benefits expenses.
The increase in salaries and benefits from the prior year is due primarily to $4.3 million in higher salaries, bonus and insurance expense related to additional headcount in addition to $1.0 million higher contract labor costs related to PPP and various ongoing departmental and bank-wide infrastructure projects, offset by $1.5 million lower mortgage commissions and incentives due to lower mortgage production for the year over year period. In addition, deferred salaries expense was $450 thousand lower this quarter due to the PPP loans and other COVID-related modifications that occurred during third quarter 2020 and reduced overall salary expense for that period.
The increase in professional fees from the prior year is primarily due to increased consulting expenses related to the various infrastructure projects discussed above. In addition, the Company recognized approximately $1.1 million in consulting expenses related to PPP forgiveness expenses during the quarter, which is not expected to recur. The increase in other noninterest expense from the prior year is due to increases of $543 thousand in charitable contributions and $430 thousand in business meals, entertainment and travel expenses primarily due to returning to work in second quarter 2021.
The linked quarter change for salaries and benefits is also reflective of higher salaries and bonus expenses of $1.4 million, primarily related to executive and senior positions added or replaced during the quarter, including signing bonuses for these positions. In addition, approximately $240 thousand in non-recurring PPP bonuses were paid during the quarter and contract labor costs were $550 thousand higher than the linked quarter due to various infrastructure projects discussed above. Also, deferred salary costs were $890 thousand lower in the current quarter as loan origination activity, including the remaining PPP Round 2 loans, were higher in the linked quarter.

Provision for Credit Losses

The Company recorded no provision for credit losses for third quarter 2021, compared to $7.6 million provision expense for third quarter 2020 and negative provision for credit losses of $6.5 million for second quarter 2021. The components of provision for credit losses in the current quarter is comprised of a $4.4 million credit provision on loans offset by a $4.4 million provision expense on off-balance sheet exposures. The zero provision in third quarter 2021 and credit provision in second quarter 2021 was primarily related to changes in the portfolio mix and improvements to the economic forecast during 2021 offset by charge-offs and specific reserves taken during the respective periods. Provision expense was elevated in the third quarter 2020 primarily due to general provision expense for economic factors related to COVID-19.
The allowance for credit losses on loans was $150.3 million, or 1.31% of total loans held for investment, net of mortgage warehouse purchase loans, at September 30, 2021, compared to $87.5 million, or 0.75% at September 30, 2020 and compared to $154.8 million, or 1.34% at June 30, 2021. The dollar and percentage increase from the prior year is primarily due to the Current Expected Credit Losses (CECL) transition adjustment while the change from the linked quarter is due primarily to improvements in the economic forecast as mentioned above.
The allowance for credit losses on off-balance sheet exposures was $6.1 million at September 30,2021 compared to $1.7 million at June 30, 2021. The increase from the linked quarter was primarily due to higher remaining expected utilization on increased unfunded commitments related to growth in the Company's construction loan and energy portfolios.

Income Taxes

Federal income tax expense of $12.6 million was recorded for the third quarter 2021, an effective rate of 19.4% compared to tax expense of $16.1 million and an effective rate of 21.1% for the prior year quarter and tax expense of $15.5 million and an effective rate of 21.0% for the linked quarter. The lower effective tax rate for the third quarter 2021 was primarily a result of 2020 provision to return adjustment and current period adjustment related to state income taxes.

Third Quarter 2021 Balance Sheet Highlights

Loans

Total loans held for investment, net of mortgage warehouse purchase loans, were $11.5 billion at September 30, 2021 compared to $11.6 billion at June 30, 2021 and $11.7 billion at September 30, 2020. PPP loans totaled $243.9 million, $490.5 million and $826.0 million as of September 30, 2021, June 30, 2021 and September 30, 2020, respectively. Loans excluding PPP loans increased $129.7 million, or 4.6% on an annualized basis, during third quarter 2021.
Average mortgage warehouse purchase loans decreased slightly to $838.5 million for the quarter ended September 30, 2021 from $850.5 million at June 30, 2021, and decreased from $894.9 million for the quarter ended September 30, 2020, a decrease of $56.4 million, or 6.3% year over year. The change from the prior year is reflective of lower volumes related to mortgage rate increases and shorter hold times for the year over year period.

Asset Quality

Total nonperforming assets increased to $82.8 million, or 0.44% of total assets at September 30, 2021, compared to $53.1 million or 0.29% of total assets at June 30, 2021, and increased from $43.2 million, or 0.25% of total assets at September 30, 2020.
Total nonperforming loans increased to $82.7 million, or 0.72% of total loans held for investment at September 30, 2021, compared to $52.5 million, or 0.45% at June 30, 2021 and $41.4 million, or 0.36 % at September 30, 2020.
The increase in nonperforming loans and nonperforming assets from the linked quarter is primarily due to two commercial relationships totaling $17.8 million and one commercial real estate loan totaling $11.7 million being added to nonaccrual during the quarter.
The increase in nonperforming loans and nonperforming assets from the prior year is primarily due to the nonaccruals mentioned above and other nonaccrual net additions of $20.5 million as well as net additions of $7.1 million in PCD loans added related to our January 1, 2021 CECL adoption, offset by net reductions of $15.7 million in loans past due 90 days and still accruing and net dispositions of other real estate owned of $1.6 million for the year over year period.
Charge-offs were 0.00% annualized in the third quarter 2021 compared to 0.13% annualized in the linked quarter and 0.01% annualized in the prior year quarter. Charge-offs were higher in second quarter 2021 due to two commercial loan charge-offs totaling $2.4 million.

Deposits, Borrowings and Liquidity

Total deposits were $15.5 billion at September 30, 2021 compared to $15.1 billion at June 30, 2021 and compared to $13.8 billion at September 30, 2020. The increase in deposits from the linked quarter is due to organic growth of $460.4 million , or 12.1% annualized for the quarter while deposits for the year over year period increased $1.7 billion, or 12.5%. Noninterest bearing deposits increased $279.1 million from June 30, 2021 and $726.4 million from September 30, 2020.
Total borrowings (other than junior subordinated debentures) were $631.7 million at September 30, 2021, a decrease of $49.3 million from June 30, 2021 and a decrease of $48.8 million from September 30, 2020. The linked quarter and annual changes reflect a $25.0 million reduction of short-term FHLB advances and a $40.0 million redemption of subordinated debentures offset by a $15.5 million draw on the Company's line of credit.

Capital

The Company continues to be well capitalized under regulatory guidelines. At September 30, 2021, its 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 11.06%, 8.94%, 11.46% and 13.64%, respectively, compared to 11.14%, 9.03%, 11.55%, and 14.23%, respectively, at June 30, 2021 and 10.24%, 9.15%, 10.66%, and 13.29%, respectively at September 30, 2020.

The Company urges you to consider all of these risks, uncertainties and other factors carefully in evaluating all such forward-looking statements made by the Company. 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. Any forward-looking statement made in this prospectus or made by the Company in any report, filing, document or information incorporated by reference in this prospectus, speaks only as of the date on which it is made. The Company undertakes no obligation to update any such forward-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 prospectus 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.
