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”) that are subject to risks and uncertainties and are made pursuant to the safe harbor provisions of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. 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 the Company's 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;

(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 and 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;

(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, the Company, 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;
