Second Quarter Financial Results

Net income for First Busey Corporation (“First Busey” or the “Company”) was $29.4 million for the second quarter of 2023, or $0.52 per diluted common share, compared to $36.8 million, or $0.65 per diluted common share, for the first quarter of 2023, and $29.8 million, or $0.53 per diluted common share, for the second quarter of 2022. Adjustments to net income for the second quarter of 2023 were immaterial, and there were no adjustments to net income for the first quarter of 2023. Adjusted net income1 was $30.1 million, or $0.54 per diluted common share, for the second quarter of 2022. Annualized return on average assets and annualized return on average tangible common equity1 were 0.96% and 13.90%, respectively, for the second quarter of 2023. Net income includes net losses on securities of $2.1 million for the second quarter of 2023, $0.6 million for the first quarter of 2023, and $1.7 million for the second quarter of 2022. Excluding these securities losses, which are largely unrealized, net income1 for the second quarter of 2023 would have been $31.0 million, resulting in diluted EPS1 of $0.55.

Pre-provision net revenue1 was $39.5 million for the second quarter of 2023, compared to $47.9 million for the first quarter of 2023 and $39.6 million for the second quarter of 2022. Adjusted pre-provision net revenue1 was $42.1 million for the second quarter of 2023, compared to $49.5 million for the first quarter of 2023 and $41.3 million for the second quarter of 2022. Pre-provision net revenue to average assets1 was 1.30% for the second quarter of 2023, compared to 1.58% for the first quarter of 2023, and 1.27% for the second quarter of 2022. Adjusted pre-provision net revenue to average assets1 was 1.38% for the second quarter of 2023, compared to 1.64% for the first quarter of 2023 and 1.33% for the second quarter of 2022.

The decline in pre-provision net revenue in the second quarter, compared to the first quarter, was primarily the result of a $7.2 million decrease in net interest income, which is the result of deposits migrating into higher cost offerings along with an increase in short-term borrowings as we progress through the current tightening cycle that began in the first quarter of 2022. Net interest margin declined from 3.13% in the first quarter of 2023 to 2.86% in the second quarter of 2023.

Our fee-based businesses continue to add revenue diversification. Excluding net securities gains and losses2, noninterest income of $30.1 million accounted for 27.7% of total operating revenue3 during the second quarter of 2023, compared to $32.5 million which accounted for 27.4% of total operating revenue for the first quarter of 2023 and $32.7 million which accounted for 30.1% of total operating revenue for the second quarter of 2022. Beginning on July 1, 2022, we became subject to the Durbin Amendment of the Dodd-Frank Act. The impact of these rules in the second quarter of 2023 was a $2.4 million reduction in fee income. Excluding the impact from the Durbin Amendment, fees for customer services were up 0.8% from the second quarter of 2022.

During 2023, and over the last several years, we have been purposeful in our efforts to rationalize our expense base given our economic outlook and our view on the future of banking. The impact of these efforts are reflected in our operating results. During a time of decades-high inflation, we have effectively managed our noninterest expense. Noninterest expense was $69.2 million in the second quarter of 2023, compared to $70.4 million in the first quarter of 2023 and $69.1 million in the second quarter of 2022. Adjusted core expense2 was $64.0 million in the second quarter of 2023, compared to $66.1 million in the first quarter of 2023 and $64.4 million in the second quarter of 2022. As we enter the second half of 2023, we expect to continue prudently managing our expenses. These efforts are helping to offset some of the inflationary pressures that exist today while allowing us to invest back into other parts of our company.

First Busey’s Conservative Banking Strategy

First Busey’s financial strength is built on a sound business strategy of conservative banking. That focus will not change now or in the future.

The Company's growth trend for portfolio loans continued during the second quarter of 2023, albeit at a moderate pace. Loans are being originated at attractive spreads while not compromising on our prudent underwriting standards. Loan growth was $21.5 million in the second quarter of 2023, compared to growth of $58.1 million in the first quarter of 2023 and $224.9 million in the second quarter of 2022. Over the last four quarters, the Company has generated $307.5 million in portfolio loan growth, equating to a year-over-year growth rate of 4.1%. Our loan to deposit ratio ended the quarter at 77.6%. We continue to believe that the economic outlook has deteriorated over the last twelve months. Given this outlook, we expect loan growth for the remainder of the year is likely to slow compared to our previous expectations and we intend to remain conservative in our underwriting and granting of credit.

The quality of our core deposit franchise is a critical value driver of our institution. Despite recent turmoil experienced in certain sectors of the banking industry, we have seen relative stability in our deposit franchise. Our granular deposit base continues to position us well, as our estimated uninsured deposits4 percentage is 26%, and 97.0% of our deposits are core deposits2. Furthermore, non-interest bearing deposits at June comprise 30.7% of our total deposits. As of June 30, 2023, our retail deposit base was comprised of more than 255,000 accounts with an average balance of $21 thousand and an average tenure of 16.3 years. Our commercial deposit base was comprised of more than 33,000 accounts with an average balance of $101 thousand and an average tenure of 12.2 years. Furthermore, we have sufficient on- and off-balance sheet liquidity to manage deposit fluctuations and the liquidity needs of our customers.

Asset quality remains strong by both historical and current industry trends. Non-performing assets were 0.13% of total assets for both the first and second quarter of 2023, compared to 0.15% for the second quarter of 2022. Furthermore, we saw a quarter-over-quarter decline in total classified assets from $103.9 million to $81.9 million in the second quarter of 2023. The Company’s results for the second quarter of 2023 include a provision expense of $0.6 million for credit losses and a provision expense of $0.3 million for unfunded commitments. The total allowance for credit losses was $91.6 million at June 30, 2023, representing 1.17% of total portfolio loans outstanding, and 580.80% of non-performing loans. The Company recorded net charge offs of $0.7 million in the second quarter of 2023, which equates to 0.04% of average loans on an annualized basis. As of June 30, 2023, our commercial real estate loan portfolio of investor-owned office properties within Central Business District5areas remains low at $10.5 million. Our credit performance continues to reflect our highly diversified, conservatively underwritten loan portfolio, which has been originated predominantly to established customers with tenured relationships with our company.

3 Operating revenue consists of net interest income plus noninterest income, net of securities gains and losses.

4 Estimated uninsured deposits consist of account balances in excess of the $250 thousand FDIC insurance limit, less intercompany accounts and collateralized accounts (including preferred deposits).

5 Central Business District areas within Busey’s footprint include downtown St. Louis, downtown Indianapolis, and downtown Chicago.

The strength of our balance sheet is also reflected in our capital foundation. In the second quarter, our tangible common equity ratio6increased to 7.18% while our Common Equity Tier 1 and Total Capital to Risk Weighted Assets ratios increased to 12.35% and 16.56%, respectively7. In fact, our regulatory capital ratios continue to provide a buffer of more than $470 million above levels required to be designated well-capitalized.

Community Banking

First Busey’s goal of being a strong community bank begins with outstanding associates. The Company is humbled to be named among the 2022 Best Banks to Work For by American Banker, the 2022 Best Places to Work in Money Management by Pensions and Investments, the 2023 Best Places to Work in Illinois by Daily Herald Business Ledger, and the 2023 Best Companies to Work For in Florida by Florida Trend magazine.

As we enter the second half of 2023, we are cognizant of the evolving economic outlook and remain focused on balance sheet strength, profitability, and growth, in that order. With our strong capital position, an attractive core funding base, and a sound credit foundation, we remain confident that we are well positioned. We are grateful for the opportunities to earn the business of our customers, based on the contributions of our talented associates and the continued support of our loyal shareholders.

Balance Sheet Growth

Our balance sheet remains a source of strength. Total assets were $12.21 billion as of June 30, 2023, compared to $12.34 billion as of March 31, 2023, and $12.36 billion as of June 30, 2022. Portfolio loans were $7.81 billion at June 30, 2023, compared to $7.78 billion at March 31, 2023, and $7.50 billion at June 30, 2022. During the second quarter of 2023, Busey Bank experienced our ninth consecutive quarter of core loan8 growth, albeit at a moderating pace, of $21.6 million. Growth was driven by our central, Florida, and northern regions. Overall growth was tempered by the reduction of $22.0 million of classified assets and a $58.0 million decline in line utilization during the quarter. As has been our practice, we remain steadfast in our conservative approach to underwriting and disciplined approach to pricing, particularly given our outlook for the economy in the coming quarters. This posture will impact loan growth in subsequent quarters.

Average portfolio loans were $7.76 billion for the second quarter of 2023, compared to $7.71 billion for the first quarter of 2023 and $7.38 billion for the second quarter of 2022. Average interest-earning assets were $11.13 billion for the second quarter of 2023, compared to $11.18 billion for the first quarter of 2023, and $11.45 billion for the second quarter of 2022.

Total deposits were $10.06 billion at June 30, 2023, compared to $9.80 billion at March 31, 2023, and $10.40 billion at June 30, 2022. Average deposits were $9.85 billion for the second quarter of 2023, compared to $9.91 billion for the first quarter of 2023 and $10.51 billion for the second quarter of 2022. Deposit growth in the second quarter of 2023 over the first quarter of 2023 was primarily related to increases in public funds and largely occurred in the last month of the quarter. Deposit fluctuations over the last several quarters were driven by a number of elements, including (1) anticipated seasonal factors, including ordinary course public fund flows and fluctuations in the normal course of business operations of certain core commercial customers, (2) the macroeconomic environment, including prevailing interest rates and anticipated future Federal Open Market Committee (“FOMC”) rate moves, as well as inflationary pressures, (3) depositors moving some funds to accounts at competitors offering above-market rates, including state-sponsored investment programs that provide rates in excess of where we can borrow in the wholesale marketplace, and (4) deposits moving within the Busey ecosystem from the bank to our wealth management group. Core deposits8 accounted for 97.0% of total deposits as of June 30, 2023. Cost of deposits was 1.09% in the second quarter of 2023, which represents a 49 basis point increase from the first quarter of 2023. Excluding time deposits, the Company’s cost of deposits was 0.81% in the second quarter of 2023, a 32 basis point increase from March 31, 2023.

Short term borrowings decreased to $212.0 million as of June 30, 2023, compared to $615.9 million as of March 31, 2023. Average short term borrowings increased to $443.8 million in the second quarter of 2023, compared to $424.3 million in the first quarter of 2023. We have sufficient on- and off-balance sheet liquidity9to manage deposit fluctuations and the liquidity needs of our customers. As of June 30, 2023, our available sources of on- and off-balance sheet liquidity totaled $6.24 billion. To help offset some of the impact of rising costs associated with increased borrowings, we increased deposit campaigns starting in the first quarter of 2023 to attract term funding and savings accounts at a lower rate than our marginal cost of funds. In addition, we instituted a company-wide incentive campaign to drive new customer account openings. Our time deposit campaigns generated increased traction and production throughout the quarter and we expect to continue to implement prudent and measured strategies to generate deposit growth. Furthermore, our balance sheet liquidity profile continues to be aided by the cash flows we expect from our relatively short-duration securities portfolio. Those cash flows were approximately $99.7 million in the second quarter and are expected to be $186.7 million over the remaining balance of 2023.

Asset Quality

Credit quality continues to be exceptionally strong. Loans 30-89 days past due totaled $5.2 million as of June 30, 2023, compared to $5.5 million as of March 31, 2023, and $5.2 million as of June 30, 2022. Non-performing loans were $15.8 million as of June 30, 2023, compared to $15.2 million as of March 31, 2023, and $17.5 million as of June 30, 2022. Continued disciplined credit management resulted in non-performing loans as a percentage of portfolio loans of 0.20% as of both June 30, 2023, and March 31, 2023, and 0.23% as of June 30, 2022. Non-performing assets were 0.13% of total assets for both the first and second quarter of 2023, compared to 0.15% in the second quarter of 2022. Our total classified assets declined from $103.9 million at March 31, 2023, to $81.9 million at June 30, 2023. The quarter over quarter decline in classified assets is largely attributable to a pay-off from a single borrower in the skilled nursing industry.

9 On- and off-balance sheet liquidity is comprised of cash and cash equivalents, debt securities excluding those pledged as collateral, brokered deposits, and First Busey’s borrowing capacity through its revolving credit facility, the FHLB, the Federal Reserve Bank, and federal funds purchased lines.

7

Net charge-offs were $0.7 million for the second quarter of 2023, $0.8 million for the first quarter of 2023, and $1.1 million for the second quarter of 2022. Our ratio of net charge-offs to average loans was 0.04% during the second quarter of 2023 and 0.03% over the last twelve months10. The allowance as a percentage of portfolio loans was 1.17% as of June 30, 2023, compared to 1.18% as of both March 31, 2023, and June 30, 2022. The allowance as a percentage of non-performing loans was 580.80% as of June 30, 2023, compared to 602.91% as of March 31, 2023, and 507.36% as of June 30, 2022.

The Company maintains a well-diversified loan portfolio and, as a matter of policy and practice, limits concentration exposure in any particular loan segment.

Net Interest Margin11 and Net Interest Income

Net interest margin was 2.86% for the second quarter of 2023, compared to 3.13% for the first quarter of 2023 and 2.68% for the second quarter of 2022. Excluding purchase accounting accretion, adjusted net interest margin11 was 2.84% for the second quarter of 2023, compared to 3.12% in the first quarter of 2023 and 2.66% in the second quarter of 2022. Net interest income was $78.7 million in the second quarter of 2023, compared to $85.9 million in the first quarter of 2023 and $75.9 million in the second quarter of 2022.

The FOMC raised rates by 25 basis points during the second quarter of 2023, and by a total of 500 basis points since the onset of the current FOMC tightening cycle that began in the first quarter of 2022. Rising rates initially have a positive impact on net interest margin, as assets, in particular commercial loans, reprice more quickly and to a greater extent than liabilities. As deposit and funding costs increase in response to the tightening rate cycle, some of the net interest margin expansion is reversed, which we began to experience in the first quarter of 2023. Components of the 27 basis point decrease in net interest margin during the second quarter of 2023 include:

•Increased loan portfolio income contributed +18 basis points

•Increases in the cash and securities portfolio yield contributed +2 basis points

•Increased non-maturity deposit funding costs contributed -23 basis points

•Increased time deposit funding costs contributed -20 basis points

•Increased borrowing costs contributed -3 basis points

•Increased net interest expense on cash flow hedges contributed -1 basis points

Based on our most recent Asset Liability Management Committee (“ALCO”) model, a 100 basis point parallel rate shock is expected to increase net interest income by 2.2% over the subsequent twelve-month period. Market competition for deposits has increased in recent months and deposit betas are likely to increase going forward, which is factored into our ALCO model. The Company continues to evaluate off-balance sheet hedging and balance sheet restructuring strategies as well as embedding rate protection in our asset originations to provide stabilization to net interest income in lower rate environments. We are committed to protecting our quality core deposit franchise and are in regular contact with our customers to proactively address their needs and concerns. Stress on liquidity resulting from the continued drain of stimulus driven inflows has impacted the banking industry. Our deposit base, particularly non-interest bearing deposits, has experienced balance attrition, but time deposit specials and retail incentive campaigns have provided sufficient funding flows to limit operational borrowings to a minimal level. As a result, deposit beta expectations have increased marginally as rotation into these higher cost of fund products has accelerated as the tightening cycle advances. Since the onset of the current FOMC tightening cycle that began in the first quarter of 2022, our cumulative interest-bearing non-maturity deposit beta has been 24.5%. Our cycle-to-date total deposit beta has been 20.3% through June 30, 2023. Deposit betas are calculated based on an average federal funds rate of 5.16% during the second quarter of 2023, which is a 47 basis point increase over the first quarter of 2023 average federal funds rate of 4.69%.

Noninterest Income

Noninterest income was $28.0 million for the second quarter of 2023, as compared to $31.8 million for the first quarter of 2023 and $31.0 million for the second quarter of 2022. Revenues from wealth management fees and payment technology solutions activities represented 70.7% of the Company’s noninterest income for the quarter ended June 30, 2023, providing a balance to spread-based revenue from traditional banking activities.

Wealth management fees were $14.6 million for the second quarter of 2023, compared to $14.8 million for the first quarter of 2023 and $14.1 million for the second quarter of 2022. The Wealth Management operating segment generated net income of $4.9 million in both the first and second quarter of 2023, compared to $5.1 million in the second quarter of 2022. First Busey’s Wealth Management division ended the second quarter of 2023 with $11.48 billion in assets under care, compared to $11.21 billion at the end of the first quarter of 2023 and $11.45 billion at the end of the second quarter of 2022. Our portfolio management team continues to produce solid results in the face of very volatile markets, and has outperformed its blended benchmark12 over the last twelve months.

Payment technology solutions revenue from FirsTech was $5.2 million for the second quarter of 2023, compared to $5.3 million for the first quarter of 2023 and $4.9 million for the second quarter of 2022. Excluding intracompany eliminations, FirsTech generated revenue of $5.6 million during the second quarter of 2023, compared to $5.7 million in the first quarter of 2023 and $5.4 million in the second quarter of 2022. The FirsTech operating segment generated net income of $0.2 million in the second quarter of 2023, an insignificant amount of net losses in the first quarter of 2023 and net income of $0.4 million in the second quarter of 2022. The Company continues to make strategic investments in FirsTech to enhance future growth, including further upgrades to the product and engineering teams to build an application programming interface ("API") cloud-based platform to provide for fully integrated payment capabilities, as well as the continued development of our BaaS platform.

Fees for customer services were $7.2 million for the second quarter of 2023, compared to $6.8 million in the first quarter of 2023 and $9.6 million in the second quarter of 2022. Year-over-year declines are attributable primarily to the impact of the Durbin Amendment on interchange revenue and, to a lesser extent, modifications implemented to overdraft and non-sufficient funds fee structures. The impact from the Durbin Amendment reduced fees for customer service by $2.4 million in the second quarter of 2023.

Net securities losses were $2.1 million for the second quarter of 2023, which were comprised of $0.2 million of realized net losses and $1.9 million of unrealized net losses on equity securities.

Other noninterest income was $1.7 million in the second quarter of 2023, a decrease from $3.6 million in the first quarter of 2023 and from $3.0 million in the second quarter of 2022. Fluctuations between the first quarter of 2023 and the second quarter of 2023 were primarily the result of decreases in swap origination fee income and venture capital investment values.

Operating Efficiency

Noninterest expense was $69.2 million in the second quarter of 2023, compared to $70.4 million in the first quarter of 2023 and $69.1 million for the second quarter of 2022. The efficiency ratio13 was 60.87% for the quarter ended June 30, 2023, compared to 56.93% for the quarter ended March 31, 2023, and 60.56% for the quarter ended June 30, 2022. The adjusted core efficiency ratio13was 58.55% for the quarter ended June 30, 2023, compared to 55.59% for the quarter ended March 31, 2023 and 59.01% for the quarter ended June 30, 2022. The Company remains focused on expense discipline.

Noteworthy components of noninterest expense are as follows:

•Salaries, wages, and employee benefits expenses were $39.9 million in the second quarter of 2023, compared to $40.3 million in the first quarter of 2023 and $38.1 million in the second quarter of 2022. Total full-time equivalents numbered 1,477 as of June 30, 2023, compared to 1,473 as of March 31, 2023, and 1,493 as of June 30, 2022.

•Data processing expense was $5.9 million in the second quarter of 2023, compared to $5.6 million in the first quarter of 2023 and $5.4 million in the second quarter of 2022. The increase was related to expenses for FirsTech transaction volume and continued Company-wide investments in technology enhancements, as well as inflation-driven price increases.

•Professional fees were $1.0 million in the second quarter of 2023, compared to $2.1 million in the first quarter of 2023 and $1.6 million in the second quarter of 2022. The quarter over quarter decrease is primarily attributable to audit and accounting fees which generally run higher during the first quarter of each year, as well as recapture of legal expenses related to the payoff of a large classified asset in the second quarter of 2023.

•Amortization expense was $2.7 million in both the first and second quarter of 2023, compared to $3.0 million in the second quarter of 2022.

•FDIC insurance expense was $1.5 million in both the first and second quarter of 2023, compared to $1.2 million in the second quarter of 2022, as a result of an FDIC final rule to increase the initial base deposit insurance assessment rate applicable to all FDIC-insured depository institutions by two basis points beginning in 2023.

•Other operating expenses were $10.2 million for the second quarter of 2023, compared to $9.8 million in the first quarter of 2023 and $11.6 million in the second quarter of 2022. The year-over-year decrease is attributable to multiple items, including expense discipline in business development and marketing expenses.

The Company's effective tax rate for the second quarter of 2023 was 20.3%, which was lower than the combined federal and state statutory rate of approximately 28.0% due to tax exempt interest income, such as municipal bond interest, bank owned life insurance income, and investments in various federal and state tax credits.

Beginning in 2024, the Company intends to adopt ASU 2023-02, which allows entities to elect to account for equity investments made primarily for the purpose of receiving income tax credits using the proportional amortization method, regardless of the tax credit program through which the investment earns income tax credits, if certain conditions are met. The proportional amortization method results in the cost of the investment being amortized in proportion to the income tax credits and other income tax benefits received, with the amortization of the investment and the income tax credits being presented net in the income statement as a component of income tax expense as opposed to being presented on a gross basis on the income statement as a component of noninterest expense and income tax expense.

Capital Strength

The Company's strong capital levels, coupled with its earnings, have allowed First Busey to provide a steady return to its stockholders through dividends. On July 28, 2023, the Company will pay a cash dividend of $0.24 per common share to stockholders of record as of July 21, 2023. The Company has consistently paid dividends to its common stockholders since the bank holding company was organized in 1980.

As of June 30, 2023, the Company continued to exceed the capital adequacy requirements necessary to be considered “well-capitalized” under applicable regulatory guidelines. The Company’s Common Equity Tier 1 ratio is estimated14 to be 12.35% at June 30, 2023, compared to 12.18% at March 31, 2023, and 11.77% at June 30, 2022. Our Total Capital to Risk Weighted Assets ratio is estimated14 to be 16.56% at June 30, 2023, compared to 16.40% at March 31, 2023, and 16.58% at June 30, 2022.

The Company’s tangible common equity15was $850.9 million at June 30, 2023, compared to $845.3 million at March 31, 2023, and $801.9 million at June 30, 2022. Tangible common equity represented 7.18% of tangible assets at June 30, 2023, compared to 7.05% at March 31, 2023, and 6.68% at June 30, 2022. The Company’s tangible book value per common share15 increased from $15.14 at March 31, 2023, to $15.25 at June 30, 2023. The ratios of tangible common equity to tangible assets15 and tangible book value per common share have been impacted by the fair market valuation adjustment of the Company’s securities portfolio as a result of the current rate environment, which is reflected in the accumulated other comprehensive income (loss) (“AOCI”) component of shareholder’s equity.

14 Capital ratios for the second quarter of 2023 are not yet finalized, and are subject to change.

Non-GAAP Financial Information

This earnings release contains certain financial information determined by methods other than U.S. Generally Accepted Accounting Principles (“GAAP”). Management uses these non-GAAP measures, together with the related GAAP measures, in analysis of the Company’s performance and in making business decisions, as well as for comparison to the Company’s peers. The Company believes the adjusted measures are useful for investors and management to understand the effects of certain non-recurring noninterest items and provide additional perspective on the Company’s performance over time.

A reconciliation to what management believes to be the most directly comparable GAAP financial measures—specifically, net interest income, total noninterest income, net security gains and losses, and total noninterest expense in the case of pre-provision net revenue, adjusted pre-provision net revenue, pre-provision net revenue to average assets, and adjusted pre-provision net revenue to average assets; net income in the case of adjusted net income, adjusted diluted earnings per share, adjusted return on average assets, average tangible common equity, return on average tangible common equity, and adjusted return on average tangible common equity; net interest income in the case of adjusted net interest income and adjusted net interest margin; net interest income, total noninterest income, and total noninterest expense in the case of adjusted noninterest expense, noninterest expense excluding non-operating adjustments, adjusted core expense, efficiency ratio, adjusted efficiency ratio, and adjusted core efficiency ratio; total stockholders’ equity in the case of tangible book value per common share; total assets and total stockholders’ equity in the case of tangible common equity and tangible common equity to tangible assets; portfolio loans in the case of core loans and core loans to portfolio loans; total deposits in the case of core deposits and core deposits to total deposits; and portfolio loans and total deposits in the case of core loans to core deposits—appears below.

These non-GAAP disclosures have inherent limitations and are not audited. They should not be considered in isolation or as a substitute for operating results reported in accordance with GAAP, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other companies. Tax effected numbers included in these non-GAAP disclosures are based on estimated statutory rates or effective rates as appropriate.

Special Note Concerning Forward-Looking Statements

3 32Q23 Earnings Investor Presentation First Busey Corporation | Ticker: BUSE Non-GAAP Financial Information This presentation contains certain financial information determined by methods other than U.S. Generally Accepted Accounting Principles (“GAAP”). Management uses these non-GAAP measures, together with the related GAAP measures, in analysis of the Company’s performance and in making business decisions, as well as for comparison to the Company’s peers. The Company believes the adjusted measures are useful for investors and management to understand the effects of certain non-recurring noninterest items and provide additional perspective on the Company’s performance over time. A reconciliation to what management believes to be the most directly comparable GAAP financial measures—specifically, net interest income, total noninterest income, net security gains and losses, and total noninterest expense in the case of pre-provision net revenue, adjusted pre-provision net revenue, pre-provision net revenue to average assets, and adjusted pre-provision net revenue to average assets; net income in the case of adjusted net income, adjusted diluted earnings per share, adjusted return on average assets, average tangible common equity, return on average tangible common equity, and adjusted return on average tangible common equity; net interest income in the case of adjusted net interest income and adjusted net interest margin; net interest income, total noninterest income, and total noninterest expense in the case of adjusted noninterest expense, noninterest expense excluding non-operating adjustments, adjusted core expense, efficiency ratio, adjusted efficiency ratio, and adjusted core efficiency ratio; total stockholders’ equity in the case of tangible book value per common share; total assets and total stockholders’ equity in the case of tangible common equity and tangible common equity to tangible assets; portfolio loans in the case of core loans and core loans to portfolio loans; total deposits in the case of core deposits and core deposits to total deposits; and portfolio loans and total deposits in the case of core loans to core deposits—appears in the appendix of this presentation. These non-GAAP disclosures have inherent limitations and are not audited. They should not be considered in isolation or as a substitute for operating results reported in accordance with GAAP, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other companies. Tax effected numbers included in these non-GAAP disclosures are based on estimated statutory rates or effective rates as appropriate.
