Independent Bank Group Reports

Second Quarter Financial Results

McKINNEY, Texas, July 23, 2018 /GlobeNewswire/ -- Independent Bank Group, Inc. (NASDAQ: IBTX), the holding company for Independent Bank, today announced net income of $29.6 million, or $1.02 per diluted share, for the quarter ended June 30, 2018 compared to $18.1 million, or $0.65 per diluted share, for the quarter ended June 30, 2017 and $29.0 million, or $1.02 per diluted share, for the quarter ended March 31, 2018.

For 2018, net income and earnings per share were positively impacted by the 14% reduction of the corporate U.S. statutory federal tax rate from 35% to 21% as a result of the enactment of the Tax Cuts and Jobs Act (TCJA), which became effective January 1, 2018.

Highlights

• Adjusted (non-GAAP) net income was $32.2 million, or $1.11 per diluted share, compared to $29.2 million, or $1.03 per diluted share, for first quarter 2018

• Adjusted (non-GAAP) return on average assets increased to 1.41% and adjusted (non-GAAP) efficiency ratio improved to 49.5%

• Strong organic growth of 18.5% of loans held for investment for the quarter (annualized) and 16.6% year to date

• Continued strong credit quality metrics with nonperforming assets of 0.17%

• Closed the Integrity Bancshares acquisition on June 1, 2018 and announced the acquisition of Guaranty Bancorp on May 22, 2018

Independent Bank Group Chairman and CEO David R. Brooks said, “Our second quarter performance reflects the continuation of our growing profitability metrics and strong loan growth reported in the first quarter. Despite some headwinds related to deposit costs, we had another record quarter for earnings, return on assets and return on equity.” Brooks continued, “We continue to build out our footprint in Houston and Colorado with strategic acquisitions, including the completion of the Integrity acquisition in June and the announcement of the Guaranty transaction in May. These acquisitions reflect the continuing execution of our planned strategy to grow the company through the acquisition of premier franchises in dynamic markets."

Second Quarter2018 Operating Results

Net Interest Income

• Net interest income was $78.9 million for second quarter2018 compared to $69.5 million for second quarter2017 and $74.0 million for first quarter 2018. The increase in net interest income from the previous year and linked quarter was due to increased average earning asset balances resulting from organic growth and the acquisition of Integrity Bancshares, as well as increased loan accretion.

• The average balance of total interest-earning assets grew by $642.0 million and totaled $8.0 billion at June 30, 2018 compared to $7.3 billion at June 30, 2017 and grew $467.4 million compared to $7.5 billion at March 31, 2018. The increase from the prior year and linked quarter is due primarily to organic growth as well as $224.8 million in average earning assets acquired in the Integrity transaction.

• The yield on interest-earning assets was 4.89% for second quarter2018 compared to 4.38% for second quarter2017 and 4.77% for first quarter 2018. The increase from the prior year and linked quarter is due primarily to higher rates on interest-earning assets due to continued increases in the Fed Funds rate during these periods. In addition, the increase from the linked quarter is due to loans and taxable securities acquired in the Integrity transaction, which had higher effective interest rates.

• The cost of interest bearing liabilities, including borrowings, was 1.27% for second quarter2018 compared to 0.77% for second quarter2017 and 1.05% for first quarter 2018. The increase from the prior year and linked quarter is primarily due to higher rates offered on our deposits, primarily commercial money market accounts and certificates of deposit, resulting both from market competition in addition to general increases in interest rates on deposit products tied to Fed Funds rates and short-term FHLB advances.

• The net interest margin was 3.97% for second quarter2018 compared to 3.81% for second quarter2017 and 4.00% for first quarter 2018. The adjusted (non-GAAP) net interest margin, which excludes purchased loan accretion, was 3.93% for second quarter2018

1

compared to 3.78% for second quarter2017 and 3.96% for first quarter 2018. The increase in the net interest margin from the prior year is primarily due to the multiple increases in the Fed Funds target rate over the year as well as earning assets shifting from cash to loans. The decrease from the linked quarter is primarily related to the aforementioned changes in our deposit rates increasing at a faster pace than our interest earning asset rates.

Noninterest Income

• Total noninterest income decreased $862 thousand compared to second quarter2017 and increased $678 thousand compared to first quarter 2018.

• The decrease from the prior year is due primarily to a $1.4 million decrease in mortgage banking revenue, offset by an $857 thousand increase in other noninterest income, primarily increases in correspondent bank earnings credits of $584 thousand and mortgage warehouse purchase fee income of $460 thousand. The decrease in mortgage banking revenue is reflective of the decrease in market demand related to the increase in interest rates for the year over year period.

• The increase from the linked quarter reflects increases of $195 thousand in mortgage banking revenue and $285 thousand in other noninterest income, primarily due to higher earnings credits offset by a $214 thousand decrease in loss on sale of securities.

Noninterest Expense

• Total noninterest expense decreased $2.2 million compared to second quarter2017 and increased $4.2 million compared to first quarter 2018.

• The decrease in expense compared to second quarter2017 is due primarily to decreases of $489 thousand in FDIC assessment and $2.2 million in acquisition expenses, offset by an increase in other noninterest expense of $1.3 million primarily due to higher deposit-related expenses as well as an increase in charitable contributions for the year over year period. The decrease in FDIC assessment expense is related to the improvement of certain Bank capital ratios used in the assessment calculation. Acquisition expenses were elevated in second quarter 2017 due to retention bonuses paid and professional fees incurred related to the Carlile transaction, which closed on April 1, 2017.

• The increase from the linked quarter is primarily related to increases of $1.6 million in salaries and benefits, $354 thousand in occupancy and $2.9 million in acquisition-related expenses offset by a decrease in other noninterest expense of $527 thousand. The increase in salaries and occupancy expense for the second quarter is primarily due to signing bonuses, additional headcount and branch locations related to the Integrity acquisition. The higher level of acquisition expense from the linked quarter is primarily due to professional fees incurred related to the completion of the Integrity Bancshares acquisition in addition to accrued termination and conversion-related expenses related to the transaction and professional fees related to the Guaranty transaction.

Provision for Loan Losses

• Provision for loan loss was $2.7 million for second quarter2018, an increase of $258 thousand compared to $2.5 million for second quarter2017 and was unchanged compared to the first quarter 2018. Provision expense is primarily reflective of organic loan growth as well as charge-offs or specific reserves taken during the respective period.

• The allowance for loan losses was $43.3 million, or 0.58% of total loans, at June 30, 2018, compared to $35.9 million, or 0.59% of total loans at June 30, 2017, and compared to $42.0 million, or 0.64% of total loans, at March 31, 2018. The dollar increases from prior periods are primarily due to additional general reserves for organic loan growth. The decrease in the allowance for loan losses as a percentage of loans from prior periods reflects that loans acquired in the Integrity transaction were recorded at fair value without an allowance at acquisition date.

Income Taxes

• Federal income tax expense of $7.5 million was recorded for the quarter ended June 30, 2018, an effective rate of 20.2% compared to tax expense of $8.6 million and an effective rate of 32.1% for the quarter ended June 30, 2017 and tax expense of $6.8 million and an effective rate of 19.0% for the quarter ended March 31, 2018. The lower tax rate in first and second quarter 2018 is primarily due to the reduction of the corporate U.S. statutory federal income tax rate from 35% to 21% as a result of the TCJA. The increase from the linked quarter is due to $723 thousand of nondeductible acquisition expenses incurred during the period.

Second Quarter2018 Balance Sheet Highlights:

Loans

• Total loans held for investment, net of mortgage warehouse purchase loans, were $7.5 billion at June 30, 2018 compared to $6.5 billion at March 31, 2018 and $6.1 billion at June 30, 2017. Loans held for investment grew by $952.3 million for the quarter, or 14.6%, $651.8 million of which was acquired in the Integrity acquisition, and $300.6 million of which was organic loan growth. Loans held for investment increased $1.4 billion from June 30, 2017, or 22.2%, $651.8 of which was acquired in the Integrity acquisition, offset by $104.3 million in loans sold with the branch sales in third and fourth quarter 2017, and $813.3 million of which was organic growth. Loans have grown organically 16.6%, annualized, from December 31, 2017. Organic loan growth for the second quarter was 18.5% on an annualized basis.

• Average mortgage warehouse purchase loans were $124.0 million at June 30, 2018 compared to $114.4 million at March 31, 2018, representing an increase of $9.5 million, or 8.3% for the quarter, and compared to $107.1 million at June 30, 2017, an increase of $16.8 million, or 15.7% year over year. The change from the linked quarter and prior year quarter is reflective of mortgage loan market activity during the respective periods.

• Commercial real estate (CRE) loans were $3.9 billion at June 30, 2018 compared to $3.5 billion at March 31, 2018 and $3.2 billion at June 30, 2017, or 51.4%, 52.4% and 51.6% of total loans, respectively.

Asset Quality

• Total nonperforming assets decreased to $16.9 million, or 0.17% of total assets at June 30, 2018, from $20.5 million, or 0.23% of total assets at March 31, 2018, and decreased from $26.1 million, or 0.30% of total assets at June 30, 2017.

• Total nonperforming loans decreased to $12.6 million, or 0.17% of total loans at June 30, 2018, from $14.9 million, or 0.23% of total loans at March 31, 2018, and decreased from $14.5 million, or 0.24% of total loans at June 30, 2017.

• The net decrease in the dollar amount of nonperforming assets and nonperforming loans from the linked quarter is primarily due to dispositions of a $1.6 million nonaccrual commercial real estate loan and three commercial nonaccrual loans totaling $1.9 million offset by the addition of two loans placed on nonaccrual status totaling $1.0 million, as well as the disposition of $1.2 million of other real estate during the quarter.

• The decrease in the dollar amount of nonperforming assets from the prior year is primarily due to dispositions in other real estate owned totaling $6.5 million, of which $4.5 million was obtained in the Carlile acquisition, in addition to the above mentioned pay-offs of nonaccrual loans in second quarter 2018. The decrease in nonperforming loans from the prior year is primarily due to the above mentioned nonaccrual dispositions in addition to a $1.3 million residential real estate pay-down and a troubled debt restructured loan pay-off totaling $778 thousand, offset by $4.4 million in additional nonaccrual loans.

• Charge-offs were 0.08% annualized in the second quarter 2018 compared to 0.01% annualized in the linked quarter and less than 0.01% annualized in the prior year quarter. The increase in the second quarter 2018 charge-offs was a result of a $342 thousand charge-off on the commercial real estate nonaccrual loan and a $998 thousand charge-off on the commercial nonaccrual loans mentioned above.

Deposits and Borrowings

• Total deposits were $7.5 billion at June 30, 2018 compared to $6.8 billion at March 31, 2018 and compared to $6.7 billion at June 30, 2017. The increase in deposits for both periods is primarily due to $593 million in deposit accounts acquired in the Integrity transaction and organic growth.

• Total borrowings (other than junior subordinated debentures) were $887.7 million at June 30, 2018, an increase of $270.1 million from March 31, 2018 and an increase of $303.4 million from June 30, 2017. The change in the linked quarter reflects the use of short term FHLB advances as needed for liquidity as well as $60 million of FHLB advances from the Integrity acquisition. The change in the prior year is due to aforementioned change in FHLB advances and the issuance of $29.3 million, net of issuance costs, of 5.0% fixed to floating rate subordinated debentures issued in fourth quarter 2017.

Capital

• Book value and tangible book value per common share (non-GAAP) increased to $50.49 and $25.23, respectively, at June 30, 2018 compared to $47.76 and $24.37, respectively, at March 31, 2018 and compared to $45.33 and $21.71, respectively, at June 30, 2017. The increase from prior year is due to the retention of earnings, the additional capital from the Integrity acquisition in second quarter 2018 and the issuance of common stock in fourth quarter 2017. The increase from the linked quarter is due to the retention of earnings and the Integrity acquisition.

• Independent Bank Group is well capitalized under regulatory guidelines. At June 30, 2018, our 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 9.31%, 9.71%, 9.67% and 11.85%, respectively, compared to 9.59%, 9.18%, 10.00%, and 12.48%, respectively at March 31, 2018. The decrease in the risk-weighted ratios from March 31, 2018 is primarily due to increased asset levels resulting from the Integrity acquisition and organic loan growth.

Forward-Looking Statements

The numbers as of and for the quarter ended June 30, 2018 are unaudited. From time to time, our comments and releases may contain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995 (the “Act”). Forward-looking statements can be identified by words such as “believes,” “anticipates,” “expects,” “forecast,” “guidance,” “intends,” “targeted,” “continue,” “remain,” “should,” “may,” “plans,” “estimates,” “will,” “will continue,” “will remain,” variations on such words or phrases, or similar references to future occurrences or events in future periods; however, such words are not the exclusive means of identifying such statements. Examples of forward-looking statements include, but are not limited to: (i) projections of revenues, expenses, income or loss, earnings or loss per share, and other financial items; (ii) statements of plans, objectives, and expectations of the Company or its management or Board of Directors; (iii) statements of future economic performance; and (iv) statements of assumptions underlying such statements. Forward-looking statements are based on the Company's current expectations and assumptions regarding its business, the economy, and other future conditions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks, and changes in circumstances that are difficult to predict. The Company's actual results may differ materially from those contemplated by the forward-looking statements, which are neither statements of historical fact nor guarantees or assurances of future performance. Many possible events or factors could affect our future financial results and performance and could cause such results or performance to differ materially from those expressed in forward looking statements. These factors include, but are not limited to, the following: (1) the Company’s ability to sustain its current internal growth rate and total growth rate; (2) changes in geopolitical, business and economic events, occurrences and conditions, including changes in rates of inflation or deflation, nationally, regionally and in the Company’s target markets, particularly in Texas and Colorado; (3) worsening business and economic conditions nationally, regionally and in the Company’s target markets, particularly in Texas and Colorado, and the geographic areas in those states in which the Company operates; (4) the Company’s dependence on its management team and its ability to attract, motivate and retain qualified personnel; (5) the concentration of the Company’s business within its geographic areas of operation in Texas and Colorado; (6) changes in asset quality, including increases in default rates and loans and higher levels of nonperforming loans and loan charge-offs; (7) concentration of the loan portfolio of Independent Bank, before and after the completion of acquisitions of financial institutions, in commercial and residential real estate loans and changes in the prices, values and sales volumes of commercial and residential real estate; (8) the ability of Independent Bank to make loans with acceptable net interest margins and levels of risk of repayment and to otherwise invest in assets at acceptable yields and presenting acceptable investment risks; (9) inaccuracy of the assumptions and estimates that the managements of Independent Bank and the financial institutions that it acquires make in establishing reserves for probable loan losses and other estimates; (10) lack of liquidity, including as a result of a reduction in the amount of sources of liquidity, that the Company currently has; (11) material increases or decreases in the amount of deposits held by Independent Bank or other financial institutions that the Company acquires and the cost of those deposits; (12) the Company’s access to the debt and equity markets and the overall cost of funding its operations; (13) regulatory requirements to maintain minimum capital levels or maintenance of capital at levels sufficient to support the Company’s anticipated growth; (14) changes in market interest rates that affect the pricing of the loans and deposits of each of Independent Bank and the financial

institutions that the Company acquires and the net interest income of each of Independent Bank and the financial institutions that the Company acquires; (15) fluctuations in the market value and liquidity of the securities the Company holds for sale, including as a result of changes in market interest rates; (16) effects of competition from a wide variety of local, regional, national and other providers of financial, investment and insurance services; (17) the institution and outcome of, and costs associated with, litigation and other legal proceedings against one of more of the Company, Independent Bank and financial institutions that the Company acquires or to which any of such entities is subject; (18) the occurrence of market conditions adversely affecting the financial industry generally; (19) the impact of recent and future legislative and regulatory changes, including changes in banking, securities and tax laws and regulations and their application by the Company’s regulators, and changes in federal government policies; (20) changes in accounting policies and practices, as may be adopted by the bank regulatory agencies, the Financial Accounting Standards Board, the SEC and the Public Company Accounting Oversight Board, or PCAOB, as the case may be; (21) governmental monetary and fiscal policies; (22) changes in the scope and cost of FDIC insurance and other coverage; (23) the effects of war or other conflicts, acts of terrorism (including cyber attacks) or other catastrophic events, including storms, droughts, tornadoes, hurricanes and flooding, that may affect general economic conditions; (24) the Company’s actual cost savings resulting from previous or future acquisitions are less than expected, it is unable to realize those cost savings as soon as expected, or it incurs additional or unexpected costs; (25) the Company’s revenues after previous or future acquisitions are less than expected; (26) the liquidity of, and changes in the amounts and sources of liquidity available to, us, before and after the acquisition of any financial institutions that the Company acquires; (27) deposit attrition, operating costs, customer loss and business disruption before and after the Company’s completed acquisitions, including, without limitation, difficulties in maintaining relationships with employees, may be greater than the Company expected; (28) the effects of the combination of the operations of financial institutions that the Company acquired in the recent past or may acquire in the future with the Company’s operations and the operations of Independent Bank, the effects of the integration of such operations being unsuccessful, and the effects of such integration being more difficult, time-consuming or costly than expected or not yielding the cost savings that the Company expects; (29) the impact of investments that the Company or Independent Bank may have made or may make and the changes in the value of those investments; (30) the quality of the assets of financial institutions and companies that the Company has acquired in the recent past or may acquire in the future being different than the Company determined or determine in its due diligence investigation in connection with the acquisition of such financial institutions and any inadequacy of loan loss reserves relating to, and exposure to unrecoverable losses on, loans acquired; (31) the Company’s ability to continue to identify acquisition targets and successfully acquire desirable financial institutions to sustain its growth, to expand its presence in its markets and to enter new markets; (32) technology-related changes are harder to make or are more expensive than expected; (33) attacks on the security of, and breaches of, the Company or Independent Bank’s digital information systems, the costs the Company or Independent Bank incur to provide security against such attacks and any costs and liability the Company or Independent Bank incurs in connection with any breach of those systems; (34) the potential impact of technology and “FinTech” entities on the banking industry generally, and (35) our success at managing the risks involved in the foregoing items; and (36) the other factors that are described in the Company’s Annual Report on Form 10-K filed on February 27, 2018, under the heading “Risk Factors,” and other reports and statements filed by the Company with the SEC. Any forward-looking statement made by the Company in this release speaks only as of the date on which it is made. Factors or events that could cause the Company’s actual results to differ may emerge from time to time, and it is not possible for the Company to predict all of them. The Company undertakes no obligation to publicly update any forward-looking statement, whether as a result of new information, future developments or otherwise, except as may be required by law.

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 loan losses and the effect of goodwill, core deposit intangibles 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.

Exhibit 99.2 Second Quarter 2018 Earnings Release Presentation July 24, 2018

Safe Harbor Statement From time to time, our comments and releases may contain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995 (the “Act”). Forward-looking statements can be identified by words such as “believes,” “anticipates,” “expects,” “forecast,” “guidance,” “intends,” “targeted,” “continue,” “remain,” “should,” “may,” “plans,” “estimates,” “will,” “will continue,” “will remain,” variations on such words or phrases, or similar references to future occurrences or events in future periods; however, such words are not the exclusive means of identifying such statements. Examples of forward-looking statements include, but are not limited to: (i) projections of revenues, expenses, income or loss, earnings or loss per share, and other financial items; (ii) statements of plans, objectives, and expectations of Independent Bank Group or its management or Board of Directors; (iii) statements of future economic performance; and (iv) statements of assumptions underlying such statements. Forward-looking statements are based on Independent Bank Group’s current expectations and assumptions regarding its business, the economy, and other future conditions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks, and changes in circumstances that are difficult to predict. Independent Bank Group’s actual results may differ materially from those contemplated by the forward-looking statements, which are neither statements of historical fact nor guarantees or assurances of future performance. Many possible events or factors could affect our future financial results and performance and could cause such results or performance to differ materially from those expressed in forward looking statements. These factors include, but are not limited to, the following: (1) The Company’s ability to sustain its current internal growth rate and total growth rate; (2) changes in geopolitical, business and economic events, occurrences and conditions, including changes in rates of inflation or deflation, nationally, regionally and in the Company’s target markets, particularly in Texas and Colorado; (3) worsening business and economic conditions nationally, regionally and in the Company’s target markets, particularly in Texas and Colorado, and the geographic areas in those states in which the Company operates; (4) the Company’s dependence on its management team and its ability to attract, motivate and retain qualified personnel; (5) the concentration of the Company’s business within its geographic areas of operation in Texas and Colorado; (6) changes in asset quality, including increases in default rates and loans and higher levels of nonperforming loans and loan charge-offs; (7) concentration of the loan portfolio of Independent Bank, before and after the completion of acquisitions of financial institutions, in commercial and residential real estate loans and changes in the prices, values and sales volumes of commercial and residential real estate; (8) the ability of Independent Bank to make loans with acceptable net interest margins and levels of risk of repayment and to otherwise invest in assets at acceptable yields and presenting acceptable investment risks; (9) inaccuracy of the assumptions and estimates that the managements of Independent Bank and the financial institutions that it acquires make in establishing reserves for probable loan losses and other estimates; (10) lack of liquidity, including as a result of a reduction in the amount of sources of liquidity, that the Company currently has; (11) material increases or decreases in the amount of deposits held by Independent Bank or other financial institutions that the Company acquires and the cost of those deposits; (12) the Company’s access to the debt and equity markets and the overall cost of funding its operations; (13) regulatory requirements to maintain minimum capital levels or maintenance of capital at levels sufficient to support the Company’s anticipated growth; (14) changes in market interest rates that affect the pricing of the loans and deposits of each of Independent Bank and the financial institutions that the Company acquires and the net interest income of each of Independent Bank and the financial institutions that the Company acquires; (15) fluctuations in the market value and liquidity of the securities the Company holds for sale, including as a result of changes in market interest rates; (16) effects of competition from a wide variety of local, regional, national and other providers of financial, investment and insurance services; (17) the institution and outcome of, and costs associated with, litigation and other legal proceedings against one of more of the Company, Independent Bank and financial institutions that the Company acquires or to which any of such entities is subject; (18) the occurrence of market conditions adversely affecting the financial industry generally; (19) the impact of recent and future legislative and regulatory changes, including changes in banking, securities and tax laws and regulations and their application by the Company’s regulators, and changes in federal government policies; (20) changes in accounting policies and practices, as may be adopted by the bank regulatory agencies, the Financial Accounting Standards Board, the SEC and the Public Company Accounting Oversight Board, or PCAOB, as the case may be; (21) governmental monetary and fiscal policies; (22) changes in the scope and cost of FDIC insurance and other coverage; (23) the effects of war or other conflicts, acts of terrorism (including cyber attacks) or other catastrophic events, including storms, droughts, tornadoes, hurricanes and flooding, that may affect general economic conditions; (24) the Company’s actual cost savings resulting from previous or future acquisitions are less than expected, it is unable to realize those cost savings as soon as expected, or it incurs additional or unexpected costs; (25) the Company’s revenues after previous or future acquisitions are less than expected; (26) the liquidity of, and changes in the amounts and sources of liquidity available to, us, before and after the acquisition of any financial institutions that the Company acquires; (27) deposit attrition, operating costs, customer loss and business disruption before and after the Company’s completed acquisitions, including, without limitation, difficulties in maintaining relationships with employees, may be greater than the Company expected; (28) the effects of the combination of the operations of financial institutions that the Company acquired in the recent past or may acquire in the future with the Company’s operations and the operations of Independent Bank, the effects of the integration of such operations being unsuccessful, and the effects of such integration being more difficult, time-consuming or costly than expected or not yielding the cost savings that the Company expects; (29) the impact of investments that the Company or Independent Bank may have made or may make and the changes in the value of those investments; (30) the quality of the assets of financial institutions and companies that the Company has acquired in the recent past or may acquire in the future being different than the Company determined or determine in its due diligence investigation in connection with the acquisition of such financial institutions and any inadequacy of loan loss reserves relating to, and exposure to unrecoverable losses on, loans acquired; (31) the Company’s ability to continue to identify acquisition targets and successfully acquire desirable financial institutions to sustain its growth, to expand its presence in its markets and to enter new markets; (32) technology-related changes are harder to make or are more expensive than expected; (33) attacks on the security of, and breaches of, the Company or Independent Bank’s digital information systems, the costs the Company or Independent Bank incur to provide security against such attacks and any costs and liability the Company or Independent Bank incurs in connection with any breach of those systems; (34) the potential impact of technology and “FinTech” entities on the banking industry generally, and (35) our success at managing the risks involved in the foregoing items; and (36) the other factors that are described in the Company’s Annual Report on Form 10-K filed on February 27, 2018, under the heading “Risk Factors”, and other reports and statements filed by the Company with the SEC. Any forward-looking statement made by the Company in this release speaks only as of the date on which it is made. Factors or events that could cause the Company’s actual results to differ may emerge from time to time, and it is not possible for the Company to predict all of them. The Company undertakes no obligation to publicly update any forward-looking statement, whether as a result of new information, future developments or otherwise, except as may be required by law. 2
